Position adjusting system of sealing and cutting machine

Abstract

The invention discloses a position adjusting system of a sealing and cutting machine. The separation stroke of an upper sealing and cutting piece and a lower sealing and cutting piece is adjusted andcontrolled through a programmable controller, a sensor and an encoder; the width position of a translation mechanism of a conveying table is adjusted and controlled through the programmable controllerand the encoder; a conveying mechanism is started or stopped in a delayed manner through the programmable controller and the sensor, so that the front and back allowances of products and films are adjusted and controlled; and the adjusting efficiency of the sealing and cutting machine is integrally improved, and the automation level and the production efficiency are improved.

Description

technical field [0001] The invention relates to the field of product packaging, and more specifically relates to a position adjustment system of a sealing and cutting machine. Background technique [0002] In the film sealing and packaging machine in the prior art, the double-folded film is sent to the film device through the film feeding device. The film device has a first conveying device, and the film device opens the film on the upper and lower sides of the first conveying device to form a U. shape, the first conveying device transports the product to be packaged, and the film is driven by the film conveying device behind; the film and the product are sent to the second conveying device behind, and the sealing and cutting mechanism set by the second conveying device performs "L" on the film. "Shape sealing and cutting, after the sealing and cutting, the film is separated from the film conveying device, and the products in it are output by the second conveying device. ...

AI Technical Summary

Problems solved by technology

In the prior art, the stopper on one side is fixed, and the stopper corresponds to the position of the rear sealing and cutting mechanism to ensure the accuracy of the position when the product is transported to the second conveying device at the rear. The first conveying device and the stopper on the other side together The film casing device adjusts the width through the translation of the driving mechanism. The current translation machine adopts the method of screw slider to adjust, but it adopts the manual driving method, which is laborious and inefficient during adjustment, which prolongs the time of shutting down and debugging. , is not conducive to the rapid sealing and packaging

[0006] 3. There is a time difference between the conveying of the film and the product. The entire film is driven to start and stop by the film conveying device. The products are conveyed at intervals on the first conveying device. When the previous product is in place, start the film conveying device to synchronize the film and the product. Advance to the second conveying device for sealing and cutting; at this time, the film conveying device is in a stopped state, the first conveying device runs until the next product is in place, and the film conveying device is started to make the film and the product advance synchronously

At present, in the industry, two sensors are installed to detect the front end and the rear end of the product. When the front end is in place, the second conveying device and the film conveying device are started to make the product and the film move synchronously. At this time, the front margin and the rear end are determined. Stop the second conveying device and the film conveying device when they are in place, and the product stops to determine the remaining margin; because different products have different sizes and specifications, the margin to be left will be different; the above method uses translation to adjust the position of the sensor To adjust the size of the margin, manpower is required to disassemble and move the position of the sensor. The adjustment accuracy is high and the efficiency is low, which prolongs the time of shutdown and debugging, which is not conducive to the rapid sealing and packaging.

[0007] In the prior art, the sealing and cutting machine uses PLC technology to control the start and stop of each conveying device, sealing and cutting mechanism, and driving mechanism, but it does not solve the above three problems well.
