Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a low-temperature film heat sealing device that allows for quick replacement of film materials. Background Technology

[0002] In the packaging production process, heat sealing equipment needs to operate for extended periods, resulting in rapid film consumption and frequent film roll replacements. However, existing film roll disassembly and assembly mechanisms are cumbersome and time-consuming, severely impacting production efficiency. Therefore, a device capable of quickly replacing film materials is needed to save replacement time and ensure production progress. As consumers pay increasing attention to packaging quality and safety, heat sealing machines need to ensure sealing strength and aesthetics. Low-temperature heat sealing technology can reduce damage to film materials, improve sealing quality, and better adapt to temperature-sensitive packaging materials, such as certain food and pharmaceutical packaging materials. Consequently, the demand for low-temperature film heat sealing equipment is increasing daily.

[0003] With increasing environmental awareness, the packaging industry is paying more and more attention to sustainable development. Low-temperature sealing technology meets environmental protection requirements and can reduce energy consumption. At the same time, the application of biodegradable or recyclable packaging materials also requires corresponding low-temperature heat sealing devices to achieve good sealing effects. However, most existing low-temperature heat sealing devices use the method of placing the film material in the middle of two rollers and using a shell with buckles to fix the film material. When the film material needs to be replaced, it cannot be detected and replaced in time, resulting in incomplete sealing of some products, leading to a decline in product quality and reduced work efficiency. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a low-temperature membrane heat sealing device that allows for rapid membrane material replacement, aiming to improve the problem of the inability to quickly replace membrane materials in the prior art.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a low-temperature film heat-sealing device for quick film material replacement, comprising a bracket, a connecting plate 1 fixedly connected to the outer wall of the bracket, a contact ring fixedly connected to the outer wall of the connecting plate 1, a sliding groove formed on the outer wall of the contact ring, a sliding column 1 slidably connected to the inner wall of the sliding groove, a sliding column 2 fixedly connected to the outer wall of the sliding column 1, a locking block slidably connected to the inner wall of the sliding column 2, a connecting post 1 fixedly connected to the outer wall of the locking block, a retaining ring 1 slidably connected to the outer wall of the connecting post 1, a spring 1 fixedly connected to the outer wall of the retaining ring 1, a spring 2 fixedly connected to the outer wall of the retaining ring 1, a retaining ring 2 fixedly connected to the outer wall of the spring 2, a pushing rod fixedly connected to the inner wall of the retaining ring 2, a handle fixedly connected to the outer wall of the pushing rod, a sleeve slidably connected to the inner wall of the pushing rod, a hollow cylinder fixedly connected to the outer wall of the sleeve, and an automatic cleaning structure slidably connected to the inner wall of the bracket. The function of the automatic cleaning structure is to automatically remove film residue from the surface of the cutter.

[0006] As a further description of the above technical solution: The automatic cleaning structure includes a light rod 1, the outer wall of which is slidably connected to the inner wall of the bracket. A connecting block is slidably connected to the outer wall of the light rod 1. A connecting post 2 is fixedly connected to the inner wall of the connecting block. A knife handle 1 is fixedly connected to the outer wall of the connecting post 2. A hot cutting knife is fixedly connected to the outer wall of the knife handle 1. A knife handle 2 is fixedly connected to the outer wall of the hot cutting knife. A scraper 1 is fixedly connected to the outer wall of the knife handle 2. A pressing shell is slidably connected to the outer wall of the connecting post 2. A linear motor is fixedly connected to the inner wall of the pressing shell. The output end of the linear motor is fixedly connected to the scraper 2.

[0007] As a further description of the above technical solution: A workbench is fixedly connected to the outer wall of the bracket, and a support leg is fixedly connected to the outer wall of the workbench.

[0008] As a further description of the above technical solution: A support plate is fixedly connected to the outer wall of the workbench, and a stepper motor is fixedly connected to the top of the support plate.

[0009] As a further description of the above technical solution: The output end of the stepper motor is fixedly connected to a pulley, the outer wall of the pulley is rotatably connected to a belt, and the inner wall of the belt is rotatably connected to a roller.

[0010] As a further description of the above technical solution: The outer wall of the bracket is fixedly connected to a second connecting plate, and the inner wall of the second connecting plate is rotatably connected to a rotating column.

[0011] As a further description of the above technical solution: A cylinder is fixedly connected to the inner wall of the bracket, a membrane inlet is opened on the outer wall of the bracket, and a rotating rod is rotatably connected to the outer wall of the contact ring.

[0012] As a further description of the above technical solution: A waste box is fixedly connected to the outer wall of the pressing shell, a through hole is opened on the outer wall of the pressing shell, and a push spring is fixedly connected to the outer wall of the pressing shell.

[0013] This utility model has the following beneficial effects: In this invention, by pulling the handle outward, the push rod moves outward, which in turn moves the second retaining ring, causing the second spring to extend. This, in turn, pulls the first retaining ring outward, compressing the first spring, causing the first connecting column to move outward, and then the locking block to move outward, disengaging it from the contact ring. At this point, the sleeve can be pushed, causing the second sliding column to slide along the inner wall of the contact ring, thus allowing the membrane material to be replaced. After replacement, the sleeve is rotated back to its original position, causing the locking block to re-insert into the contact ring, fixing the hollow cylinder. This achieves the purpose of quickly replacing the membrane material, thereby improving product quality and increasing work efficiency.

[0014] In this invention, after heat sealing is completed, the hot cutting blade is lifted, the linear motor is started, and the scraper blade 2 slides left and right to scrape off the residue on the surface of the hot cutting blade. The cylinder is then started again, which moves the connecting block downward, which in turn moves the connecting column 2 downward, compressing the push spring and pushing the pressing shell downward. Once the pressing shell presses against the surface of the film material, the hot cutting blade continues to move downward, causing the blade handle 2 to move downward, which in turn moves the scraper blade 1 downward, scraping the residue scraped off the surface of the scraper blade 2 into the waste box, thus achieving automatic cleaning. The structure is simple and the working efficiency is high. Attached Figure Description
