Embodiment 1

[0043] The embodiment of the present application discloses a packaging bag making machine. refer to figure 1 and figure 2 , the packaging bag making machine includes a fixed seat 1, a supporting traction mechanism, a heat-sealing mechanism and a cutting mechanism. The platform 2 is reciprocally lifted and lowered. The lower surface of the hot pressing platform 2 is provided with a plurality of parallel and elongated hot pressing molds 3 . The hot pressing platform 2 is provided with a cooling assembly for cooling the hot pressing molds 3 .

[0044] refer to figure 2 and image 3 , the upper end surface of the fixed seat 1 is provided with a semi-heat insulation sheet 4 directly below the hot pressing die 3, the semi-heat insulating sheet 4 is made of flexible material and completely covers a plurality of hot pressing dies 3, and the semi-heat insulating sheet 4 is set as non-woven fabric One of heat-resistant fabrics such as knitted fabrics and cotton fabrics. In the emb...

Embodiment 2

[0059] The embodiment of the present application discloses a packaging bag making machine, referring to Figure 4 , the difference with Embodiment 1 is that: the drive assembly includes a stepper motor 22 fixed on one of the supports 31, the output end of the stepper motor 22 is coaxially fixed with one of the installation rods 5, and the installation rod 5 rotates Connected to the fixed seat 1, the semi-insulation sheet 4 is tensioned and wrapped in a ring shape on the arcuate peripheral walls of the two installation rods 5, and the arcuate peripheral walls of the installation rods 5 are covered with a rubber layer (not shown in the figure ).

[0060] When the stepper motor 22 drives its output end to rotate, it drives one of the installation rods 5 to rotate, and when the installation rod 5 is stepping and rotating, the other installation rod 5 is driven to step and rotate through the tensioned and coated semi-insulation sheet 4, so that the hot pressing mold 3. Contact wit...

Abstract

This application relates to a packaging bag making machine, which relates to the field of packaging production equipment, which includes a fixed seat, a supporting traction mechanism, a heat-sealing mechanism and a cutting mechanism. , the fixed seat is provided with a lifting assembly for driving the hot pressing table to and fro. Cooling assembly for cooling down; the upper end surface of the fixed seat is provided with a semi-heat insulation sheet directly below the hot pressing die, and the half heat insulating sheet is made of flexible material and completely covers multiple hot pressing dies. The application has the protection of the packaging bag by setting the semi-heat insulation sheet, which can effectively avoid the probability of the packaging bag being scalded when the production line is replaced and debugged, and effectively improves the production efficiency when the product line is replaced.

Description

technical field [0001] The present application relates to the field of packaging production equipment, in particular to a packaging bag making machine. Background technique [0002] At present, when packaging products, plastic packaging bags are mostly used. Generally, the packaging bags are sealed on three sides, and the other side is sealed or equipped with a self-sealing strip after the product is loaded. However, the production of plastic packaging bags requires To the bag making machine, the conventional bag making machine generally unwinds the plastic packaging film, cuts it into upper film and lower film, and then heat-presses the upper film and lower film to seal the edges, and after the three sides are heat-pressed and bonded respectively Trimming and trimming are also required, resulting in the final production of plastic bales-bags that are open on one side. [0003] The existing patent announcement number is the Chinese patent CN111564600A, which proposes a high...
