Description

Technical Field

[0001] The utility model relates to the technical field of pedal sealing machines, and particularly relates to a pressing plate device for a pedal sealing machine. Background Art

[0002] The pedal sealing machine uses films such as PE, PVC, and POF as materials, wraps them around products or packages, and then cuts corners and seals them. It is widely used in the sealing and packaging of industries such as light industry, cultural supplies, arts and crafts, candies, hardware, and electrical components. There are certain drawbacks in the existing pedal sealing machines during use. After long-term use, the pressing plate is constantly subjected to hot and cold alternation, which easily causes serious damage and needs to be frequently replaced. The pressing strip is connected by bolts, making disassembly and assembly inconvenient. When the user steps on the pedal to press down the pressing plate, the product is sealed by using the fusibility of the film when it encounters high temperature. However, the film on the product is not completely cooled after sealing, which is likely to cause burns. Therefore, we propose a pressing plate device for a pedal sealing machine.

Limiting plates 303 are movably installed at both side positions on the upper surface of the second mounting plate 301. There are two groups of limiting plates 303, and the limiting plates 303 can slide back and forth on the second mounting plate 301. Push plates 302 are fixedly installed on the upper surfaces of the limiting plates 303. A second screw hole 304 is provided at the middle position on the upper surface of the second mounting plate 301. The first mounting structure 2 and the second mounting structure 3 are installed by embedding the limiting plates 303 inside the embedding grooves 205 and behind the embedding blocks 202. The handle 204 is embedded and installed inside the first screw hole 203 and the second screw hole 304. Threads are provided on the surface of the handle 204. The support rod 1 is fixedly installed on the rear surfaces of the fixed plates 206 respectively. The pressing plate body 4 includes a U-shaped groove 401, a slider 402, a pressing strip 403, a connecting plate 404, a sliding groove 405, and a through hole 406. Connecting plates 404 are embedded and installed on both side surfaces of the U-shaped groove 401. Sliding grooves 405 are provided at the front and rear adjacent surfaces of the connecting plates 404. There are four groups of sliding grooves 405 in total. Sliders 402 are embedded and installed inside the sliding grooves 405. The pressing strip 403 is fixedly connected between the sliders 402. Through holes 406 are provided at the middle positions of the adjacent surfaces of the connecting plates 404. The cooling structure 5 includes an airbag 501 and an air tube 502.

The cooling structure 5 is installed by embedding the airbag 501 inside the U-shaped groove 401 and above the pressing strip 403. The air tubes 502 are embedded and installed inside the through holes 406.

[0023] The implementation principle of the pressing plate device for a pedal-operated sealing machine in this application is as follows: During use, the worker steps on the pedal to drive the support rod 1 to drive the pressing plate main body 4 to press down, so as to perform the sealing work. The support rod 1 and the second installation structure 3 can be disassembled by the first installation structure 2, and after sealing, the cooling structure 5 is used for cooling treatment; when it is necessary to disassemble the pressing plate main body 4, remove the handle 204 inside the first screw hole 203 and the second screw hole 304, and lift the first installation plate 201 upward, so that the embedded block 202 is away from the embedded groove 205. At this time, the push plate 302 can be pulled forward, so that the limiting plate 303 moves inside the embedded groove 205, and thus the limiting plate 303 can be taken out from the inside of the embedded groove 205. At this time, the first installation plate 201 and the second installation plate 301 can be separated; when performing the sealing work, the U-shaped groove 401 presses down and makes the heating wire and the film embedded into the inside of the U-shaped groove 401. The connecting plate 404 moves upward under the extrusion action, so that the slider 402 moves inside the sliding groove 405 and squeezes the airbag 501. The air inside the airbag 501 is discharged through the air pipe 502 inside the through hole 406. When the U-shaped groove 401 is lifted, the pressing strip 403 moves downward under its own gravity, so that the surrounding air enters the airbag 501 through the air pipe 502, thereby accelerating the air flow speed below the pressing strip 403 and achieving the purpose of quickly cooling the film.
