First, the advantages of Shanghai Guangzhi granule packing machine

1. Advanced performance, high strength, low noise, compact structure, stable operation, convenient maintenance and long service life.

2, high degree of automation, the machine from vertical seal, slitting, horizontal sealing, filling and loading, batch number, cut easily cut, cut line, cross cut, until the output of the finished bag can be completed in one time.

3. Roller heat sealing, four-side sealing, high-speed multi-bag packaging, and the bag type is flat and exquisite, and the packaging efficiency is high.

4. The adjustment is quick and convenient. The bag length can be adjusted steplessly without changing the mold, and the actuators such as vertical seal, cross seal, filling, batch number, cross-line, cross-cut can be adjusted through the man-machine interface.

5. The filling metering is accurate, and the swinging feeding tube is equipped with a triangular adjustable measuring cup feeding mechanism, so that each column can be independently adjusted and measured. At the same time, the lifting vibration feeding device can be configured for materials with poor fluidity.

6. The whole machine adopts PLC automatic control, variable frequency stepless speed regulation, all actuators are driven by servo motor, which runs smoothly and synchronous positioning is very accurate.

7, using photoelectric tracking system to ensure the automatic version of the double-sided pattern of the packaging bag, and has an automatic counting function.

8. It has strong adaptability to the packaging material. The heat sealing roller has high-precision automatic temperature control function, which can adapt to various packaging film produced at home and abroad.

9. Applicability is strong. The cutting method can be used for both flat cutting and bag cutting, and optional ink wheel printer and various automatic alarm stop functions.

10, multi-row packaging machine generally small volume when the output is relatively large. The speed is relatively fast for the annual production of 30 million bags of granules in the pharmaceutical industry.

Second, the change of the standard method:

(1) Comparison of benchmarking methods

In the function of the granule packing machine, the benchmarking function is one of the important functions of the Zui. The quality of the benchmarking function determines the performance of the equipment, the accuracy of the benchmarking, the length of the benchmarking process, and determines the product quality and production cost. The following compares the differences between the old and new models.

Old-fashioned granule packing machine benchmarking method

1. Adjust the length of the bag: Before adjusting the mark, ensure that the length of the actual bag is the same as the length of the cursor point, in order to continue the following operations. When adjusting the handwheel of the stepless governor, the equipment must be in operation. When measuring the length of the bag, you must first let the device go through about 10 bags before measuring (the handwheel of the stepless governor adjusts the bag clockwise and the bag is shortened counterclockwise). When adjusting the bag length, you need to close the mark switch.

2. Manually adjust the benchmarking in the “Position Correction” of the man-machine interface, and correct the calibration to make the horizontal seal to the cursor point. (The jog master will adjust the alignment and negative repair when the horizontal seal is about to be sealed.)

3. Adjust the alignment target to align the cursor point. (The green light of the standard photoelectric head turns red)

4. Set the current angle at this time to the benchmark. The calibration accuracy of the rotary encoder is usually set to 2, and the calibration correction amount is usually set between 10 and 30 according to the speed of the calibration motor. The mechanical cam box must manually adjust the cam position and angle according to experience.

5. Turn on the benchmark switch and start the host to observe the running status of the target.

6. After the host is running, observe the change of the benchmark in the benchmark setting column in the man-machine interface. When the interface shows that the punctuation is normal, observe the actual cursor point. If the actual cursor point is above the horizontal seal, move the beaconed photo head forward (the actual cursor point is offset by how much the target photo head is shifted). The punctuation will move down, and then observe the interface display until the interface display and the actual cursor are normal. Conversely, if the actual cursor is below the horizontal seal, the target photohead should be moved backwards until the actual cursor point and interface display are normal.

7. If the interface is displayed in the running process, the normal display is converted and the repair time is longer than the normal time, indicating that the bag length is too short, and the bag length should be adjusted longer. On the other hand, if the calibration and normal conversion are displayed and the negative repair time is long, the length of the bag is too long, and the length of the bag should be shortened. If there is a direct change from positive repair to negative repair, the speed of the marked motor is too fast, and the speed of the marked motor should be slowed down (the value of the calibration correction is changed)

(2) Comparison of loading structure

The performance of the feeding mechanism is crucial in the production of the granule packing machine, which determines the quality of the product and the production efficiency.

Old-fashion loading methods are two

1. Pull-type cutting of toothed belt drive

The structure is slightly improved on the basis of the original surveying and mapping machine type. The original Korean model feeding method is the whole feeding metering plate, the pallet is single-pass independent type, and the improved type is the integral pallet. The single-track independent pallet has the disadvantages of high precision of parts processing and inconvenient maintenance of replacement parts, and the adjustment is also cumbersome. Although the improved type is changed to the overall pallet, it is convenient to replace and repair and adjust, but there are leakage powder, serious environmental pollution, and large frictional resistance. Especially when the sugar content in the material is high, the frictional resistance is larger, which may cause the transmission to be unstable. The noise of the whole machine is increased.

2, swinging cutting method

The structure draws on the cutting method of a certain Italian model. The original feeding method is the swinging double-side cutting, which requires the machining precision of the parts to be very high. This method can be independently adjusted in a single way, with high cutting speed and high efficiency, but the material requirements are also high (the particles must be uniform and the fluidity is good). The disadvantage is that the single-channel feeding is two sets of measurement on both sides. If the material is not ideal, when the one-side measurement is out of tolerance, the adjustment is very difficult. Under the operating state of the equipment, it is not easy to distinguish which side of the measurement is problematic. Adjustment errors can result in greater waste. In view of this problem, the improvement is the oscillating one-side blanking, the metering device on one side is eliminated, and the powder tray is used instead. Although the adjustment is convenient, there are still three main drawbacks: 1The swinging pipe is a funnel type, that is, the upper and the lower are small, and the material is slender through the pipeline, and the material will flow at the interface of the size of the pipe when flowing downward. The extrusion pressure is generated, and if the uniformity of the particles is not good, the measurement accuracy is greatly affected. 2 The movement track of the swinging pipe is an arc, and the gap with the measuring bucket must be adjusted properly, otherwise it will cause the error of the loading. 3. A certain amount of training is required for the operator.

3. Newly changed materials

The structure fully considers the shortcomings of the old-fashion loading mechanism, and is improved to the flat-type feeding. The movement track of the material pipe is a reciprocating linear type, the upper and lower positions of the material pipe are adjustable, the material is shortened through the pipeline, and the metering plate and the powder feeding plate are The gap can be adjusted to a minimum, so that the stacking tray accumulates very little material and the cleaning cycle becomes longer. Moreover, the diameter of the material tube is reasonable, the material circulation is smooth, and the measurement is more accurate.
