Description

Technical Field

[0001] The utility model relates to the technical field of bag-making machinery, in particular to an internal pressing plate of a bag-making machine and a sealing and cutting mechanism of a bag-making machine. Background Art

[0002] At present, when mechanical equipment makes bags of degradable materials or plastic products, a copper knife structure is used to heat the bags for the sealing and cutting process. There are also many external pressing plates in the market. Installing the external pressing plate outside will make it inconvenient to install the high-temperature cloth. Each time the high-temperature cloth is installed, the external pressing plate needs to be removed, and after the high-temperature cloth is installed, the pressing plate needs to be reinstalled. Repeated disassembly is very troublesome, and many users cannot guarantee the accuracy during installation. In addition, in the prior art, the copper knife seals first, and then the middle cutting knife cuts the product while pressing the product. Because the copper knife has a certain temperature and needs to seal the product, under the action of its own temperature and the downward cutting force of the middle cutting knife, the pressed product is easily disconnected from the sealing position by the downward pressure of the blade, resulting in the middle cutting knife being unable to cut the product and causing waste products. Therefore, it is necessary to design a new pressing plate structure to solve the above technical problems. Summary of the Utility Model

[0003] Therefore, the utility model provides an internal pressing plate and a sealing and cutting mechanism of a bag-making machine to solve the above problems in the prior art.

The cutting blade of the cutter cuts the product in the middle of the pressing plate. When producing the product, the pressing plate first presses the product, then the cutter cuts the product, and then the outer copper knife seals the product. No stretching is generated to the product during the production process, effectively preventing the product from being torn off at the sealing position. The whole pressing plate is installed in a built-in manner, and the pressing plate does not need to be removed when replacing the high-temperature cloth, which is more convenient to use.

[0015] According to the second aspect of the utility model, a bag-making machine sealing and cutting mechanism uses the built-in pressing plate described in the first aspect, and further includes a copper knife, a cutter and a hot cloth reversing roller. The copper knife is arranged outside the pressing plate;

[0016] The cutter is arranged in the cutter receiving groove, and the cutting edge of the cutter is slightly lower than the bottom of the pressing plate;
