Description

Technical Field

[0001] The utility model relates to the field of film production, in particular to an easy-tear line imprinting device used for film production. Background Art

[0002] The film is a thin, soft, transparent sheet made of plastic, adhesive, rubber or other materials. After the film is produced and processed, in order to facilitate tearing of the film, a tear line will be embossed on the surface of the film, so corresponding embossing equipment is required.

[0003] In actual use, the existing film tear line stamping equipment often uses a serrated blade to press the film, so that the film surface forms an easy tear line. However, when the serrated blade is pressed, the film is not cut thoroughly, which affects the subsequent tearing effect, and the processing quality of the easy tear line is average. Therefore, we propose an easy tear line stamping equipment for film production. Utility Model Content

[0004] The utility model aims to provide a tear line imprinting device for film production, which solves the problems raised in the background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tear line imprinting device for film production, comprising a frame, a lifting plate is provided in the inner cavity of the frame, electric push rods are fixed on both sides of the top of the frame, the push rods of the electric push rods pass through the top of the frame and are fixedly connected to the top of the lifting plate, a plurality of evenly distributed electric heating blocks are fixed at the middle of the bottom of the lifting plate, pressure plates are provided on both sides of the bottom of the lifting plate, and limiting rods are fixed at the four corners of the top of the pressure plate, the limiting rods movably pass through the lifting plate, and the outer wall of the limiting rod is provided with a spring, and the two ends of the spring are respectively fixedly connected to the lifting plate and the pressure plate.

[0006] By adopting the above technical solution, when the film is processed with an easy-tear line, the film is passed through the frame, and the electric push rod is started to drive the lifting plate down, so that the electric heating block is pressed on the surface of the film to perform perforation on the film, thereby forming a plurality of circular holes distributed in a straight line, thereby forming an easy-tear line.

[0007] As a preferred embodiment of the utility model, smoke collecting hoods are fixed on both sides of the bottom of the pressing plate corresponding to the electric heating block, and the top of the smoke collecting hood is connected to an external smoke extraction pipe.

[0008] By adopting the above technical solution, when the film is perforated by the electric heating block, negative pressure is generated by the external smoke exhaust pipe, so that the harmful gas can be extracted by the smoke collection hood for centralized treatment, thereby avoiding harm to surrounding workers.

[0009] As a preferred embodiment of the utility model, a matching rubber pad is fixedly glued to the bottom of the pressing plate.

[0010] By adopting the above technical solution and setting the rubber pad, stability is ensured when pressure is applied to the film.

[0011] As a preferred embodiment of the present invention, mounting plates are fixed to both side walls of the frame, and mounting holes are provided on both sides of the surface of the mounting plates.

[0012] By adopting the above technical solution and setting the mounting holes, it is convenient to install and fix the entire device.

[0013] As a preferred embodiment of the utility model, both side walls of the inner cavity of the frame are provided with limit slide grooves, the inner cavity of the limit slide grooves is plugged with an adaptive limit slider, and the outer wall of the limit slider is fixedly connected to the end face of the lifting plate.

[0014] By adopting the above technical solution, when the lifting plate is being lifted, the limiting slider slides in the limiting slide groove, thereby limiting the lifting trajectory of the lifting plate, thereby ensuring the lifting stability of the lifting plate.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] The easy-tear line stamping device for film production of the technical solution of the present application has a plurality of evenly distributed electric heating blocks fixed at the middle of the bottom of the lifting plate, so that when the easy-tear line is processed on the film, the lifting plate descends so that the electric heating blocks are stamped on the surface of the film, so that a plurality of holes distributed in a straight line are formed on the surface of the film, thereby forming an easy-tear line, thereby improving the processing quality of the easy-tear line;

[0017] After the lifting plate descends, the pressing plate will press on the surface of the film, thereby applying pressure to the film on both sides of the film's tear line processing area, thereby ensuring the stability of the film and preventing film wrinkles from affecting the tear line processing quality;

[0018] Smoke hoods are installed on both sides of the bottom of the lifting plate. The harmful gases generated when the electric heating block is hot-melt holes in the film can be extracted using an external smoke extraction pipe, thereby preventing the diffusion of harmful gases from causing harm to on-site workers.

[0025] See also Figure 1-3 The utility model provides a technical solution: an easy-tear line stamping device for film production, comprising a frame 1, an inner cavity of the frame 1 is provided with a lifting plate 2, electric push rods 3 are fixed on both sides of the top of the frame 1, the push rods of the electric push rods 3 pass through the top of the frame 1 and are fixedly connected to the top of the lifting plate 2, and a plurality of evenly distributed electric heating blocks 21 are fixed at the middle of the bottom of the lifting plate 2. When the film is processed with an easy-tear line, the film is passed through the frame 1, and the electric push rods 3 are started to drive the lifting plate 2 to descend, so that the electric heating blocks 21 are pressed on the surface of the film to perform perforations on the film, thereby forming a plurality of round holes distributed in a straight line, and then forming an easy-tear line;

[0026] Furthermore, mounting plates 11 are fixed to both side walls of the frame 1, and mounting holes 12 are provided on both sides of the surface of the mounting plates 11. The arrangement of the mounting holes 12 facilitates the installation and fixing of the entire device.

[0027] Furthermore, both side walls of the inner cavity of the frame 1 are provided with limit slide grooves 13, and the inner cavity of the limit slide grooves 13 is plugged with an adapted limit slider 14, and the outer wall of the limit slider 14 is fixedly connected to the end surface of the lifting plate 2. When the lifting plate 2 is lifted or lowered, the limit slider 14 slides in the limit slide groove 13, thereby limiting the lifting trajectory of the lifting plate 2, thereby ensuring the lifting stability of the lifting plate 2;

[0028] like Figure 1 and 2As shown; pressing plates 22 are arranged on both sides of the bottom of the lifting plate 2, and limiting rods 23 are fixed at the four corners of the top of the pressing plate 22. The limiting rods 23 are movable and penetrate the lifting plate 2, and the outer wall of the limiting rods 23 is sleeved with springs 24. The two ends of the spring 24 are respectively fixedly connected to the lifting plate 2 and the pressing plate 22. When the lifting plate 2 descends and the electric heating block 21 is used to emboss and open a hole in the film, the pressing plate 22 will first press on the surface of the film. At this time, the pressing plate 22 will compress the spring 24, thereby applying pressure to the film, thereby ensuring the stability of the film, and then ensuring the accuracy of the opening;

[0029] Furthermore, a matching rubber pad is fixedly glued to the bottom of the pressing plate 22, and the setting of the rubber pad ensures stability when applying pressure to the film;

[0030] like Figure 1 and 2 As shown; smoke hoods 25 are fixed on both sides of the bottom of the pressing plate 22 corresponding to the electric heating block 21, and the top of the smoke hood 25 is connected to an external smoke extraction pipe. When the electric heating block 21 is used to perforate the film, the external smoke extraction pipe is used to generate negative pressure, so that the smoke hood 25 can be used to extract the harmful gas for centralized treatment, thereby avoiding harm to the surrounding staff.

[0031] The implementation principle of the easy-tear line stamping equipment for film production in the present application is as follows: first, the device is installed at the film processing location, and then the film is passed through the frame 1. When the film is processed with the easy-tear line, the electric push rod 3 is started to drive the lifting plate 2 to descend, so that the electric heating block 21 is pressed on the surface of the film to perform ironing on the film, thereby forming a plurality of circular holes distributed in a straight line, and then forming an easy-tear line. When the lifting plate 2 descends and the electric heating block 21 is used to stamp and open holes in the film, the pressing plate 22 will first press on the surface of the film. At this time, the pressing plate 22 will compress the spring 24, thereby applying pressure to the film, thereby ensuring the stability of the film, and then ensuring the accuracy of the opening. At the same time, when the electric heating block 21 is used to iron holes in the film, negative pressure is generated by an external smoke exhaust pipe, so that the harmful gas generated can be extracted by the smoke collection hood 25 for centralized treatment, thereby avoiding harm to surrounding staff.
