An anti-scald device for a heat-sealing packaging machine

Abstract

This utility model relates to the field of heat-sealing equipment technology, and in particular to an anti-scalding device for heat-sealing packaging machines. The technical solution includes a pair of handles and a pair of heat-sealing plates, as well as a pair of transparent covers that are closed and connected to the heat-sealing plates. A second rotating block is fixedly connected to the center of one of the heat-sealing plates. This utility model utilizes the cooperation of the handles, transparent covers, abutting mechanism, and pulling mechanism. When using the anti-scalding device, pressing the handle causes the arc-shaped groove of the clamping block to abut against the conical block, driving the pull rope to cause the triangular abutting block on the insert plate to abut against the limiting groove of the transparent cover, thus opening the transparent cover to expose the heat-sealing plate for sealing. Releasing the handle causes the return spring to immediately close the transparent cover, and the triangular abutting block re-engages into the limiting groove, preventing the operator from touching the heat-sealing plate. This avoids the problem of burns caused by contact with high-temperature surfaces due to exposed heat-sealing plates and insufficient protection in hand-operated sealing machines, resulting from improper manual pressing, thus ensuring operational safety.

Description

Technical Field

[0001] This utility model relates to the field of heat sealing equipment technology, and in particular to an anti-scalding device for heat sealing packaging machines. Background Technology

[0002] Heat-sealing packaging machines are a general term for equipment that uses heat to seal packaging materials, and they are widely used in many industries such as food, pharmaceuticals, and daily necessities. Currently, hand-operated pliers sealing machines, as a type of heat-sealing packaging machine, pose certain safety hazards during operation. Because the heat source of its heat-sealing plate is exposed, and most lack sufficient insulation or protective structures, operators need to manually press the pliers arms, which brings their fingers close to the heated area. If the fingers are not properly positioned, applied unevenly, or touched before the equipment has cooled down, they can easily come into contact with the hot surface, leading to burns. Utility Model Content

[0003] The purpose of this utility model is to address the problem that current hand-operated pliers sealing machines are heat-sealing packaging machines, where the heat source of the heat-sealing plate is exposed and lacks sufficient heat insulation protection during operation. This requires manually pressing the pliers arm to bring the fingers close to the heating area, and improper positioning, uneven force, or touching the hot surface before the equipment has cooled down can easily lead to burns. Therefore, this utility model proposes an anti-scalding device for heat-sealing packaging machines.

[0004] The technical solution of this utility model is as follows: A scalding protection device for a heat-sealing packaging machine, comprising a pair of handles and a pair of heat-sealing plates, and further comprising: a pair of transparent covers, which are closedly connected to the heat-sealing plates; a second rotating block is fixedly connected to the middle of one heat-sealing plate, and a first rotating block is fixedly connected to the middle of the other heat-sealing plate; the first and second rotating blocks are rotatably connected alternately; a connecting plate is fixedly connected to one end of each handle, and the connecting plate is fixedly connected to the corresponding end of the first and second rotating blocks; an actuating mechanism, which is provided on the first and second rotating blocks to open the transparent cover; and a pulling mechanism installed on the connecting plate that drives the actuating mechanism to open by pressing the handle.

[0005] Optionally, the abutting mechanism includes a limiting port in the middle of the transparent cover to lock the corresponding first rotating block and second rotating block. The transparent cover has a limiting groove. The first rotating block and the second rotating block are fixedly connected to a sleeve. The sleeve is slidably connected to an insert plate. One end of the insert plate is fixedly connected to a triangular abutment that is locked into the limiting groove. The middle of the limiting port is provided with a pair of return springs. One end of the return spring is fixedly connected to the inner wall of the limiting port, and the other end of the return spring is fixedly connected to the corresponding first rotating block and second rotating block.

[0006] Optionally, a locking block is fixedly connected to the end of the triangular abutment block away from the insert plate.

[0007] Optionally, the pulling mechanism includes a conical block disposed in the middle of one end of the handle. One end of the conical block is fixedly connected to an H-shaped sliding plate that holds a pair of connecting plates. Each connecting plate has a through hole, and a rotating rod is rotatably connected inside each through hole. Each connecting plate is provided with a pull rope. One end of the pull rope is fixedly connected to a corresponding insert plate, and the other end of the pull rope moves through the through hole and is fixedly connected to the conical block.

[0008] Optionally, each of the rotating rods has a groove in the middle to hold the insert plate.

[0009] Optionally, a clamping block is fixedly connected to the end of the handle near the connecting plate, and an arc-shaped groove is provided on the end of the clamping block away from the handle to abut against the conical block.

[0010] Optionally, a pair of clamping plates for holding the transparent cover are fixedly connected to both outer walls of the first and second rotating blocks.

[0011] Optionally, the middle part of each clamp is provided with a plurality of ball bearings arranged in a linear pattern.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention utilizes a combination of a handle, a transparent cover, a stop mechanism, and a pull mechanism. When using the anti-scalding device, pressing the handle causes the arc-shaped groove of the clamping block to abut against the conical block, pulling the rope to cause the triangular stop block on the insert plate to abut against the limiting groove of the transparent cover, thus opening the transparent cover to expose the heat-sealing plate for sealing. Releasing the handle causes the return spring to immediately close the transparent cover, and the triangular stop block re-engages in the limiting groove, preventing the operator from touching the heat-sealing plate. This avoids the problem of burns caused by exposed heat-sealing plates and insufficient protection in hand-operated sealing machines, resulting from improper manual pressing and contact with high-temperature surfaces, thus ensuring operational safety.

[0025] Example

[0026] like Figures 1 to 4 As shown, this utility model proposes an anti-scalding device for a heat-sealing packaging machine, including a pair of handles 1 and a pair of heat-sealing plates 6. A resistance wire is embedded inside the heat-sealing plate 6. When energized, the resistance wire heats up, causing the plate to heat up through heat conduction, achieving heat sealing upon contact with the packaging material. It is also often equipped with a temperature controller, using a thermocouple sensor to monitor the temperature and maintain the heat-sealing plate within a set temperature range, ensuring stable sealing quality. A pair of transparent covers 5 are closed and connected on the heat-sealing plate 6. The transparent covers 5 are made of high-temperature resistant transparent plastic (such as polycarbonate PC), which has good transparency and high-temperature resistance, can withstand the high-temperature environment near the heat-sealing plate, and facilitates observation of the sealing operation. A second rotating block 4 is fixedly connected to the middle of one heat-sealing plate 6, and a first rotating block 3 is fixedly connected to the middle of the other heat-sealing plate 6. The first rotating block 3 and the second rotating block 4 are alternately rotatably connected. A connecting plate 2 is fixedly connected to one end of each handle 1, and the connecting plate 2 is fixedly connected to the corresponding end of the first rotating block 3 and the second rotating block 4.

[0027] Among them, such as Figures 1 to 3As shown, the first rotating block 3 and the second rotating block 4 are provided with abutment mechanisms to open the transparent cover 5. The abutment mechanisms include limiting openings 51 in the middle of the transparent cover 5 that lock the corresponding first rotating block 3 and the second rotating block 4. Each transparent cover 5 has a limiting groove 52. Each first rotating block 3 and the second rotating block 4 is fixedly connected to a retaining sleeve 342, which provides a sliding track for the insert plate 349. Each retaining sleeve 342 is slidably connected to an insert plate 349. One end of the insert plate 349 is fixedly connected to a triangular abutment 341 that engages in the limiting groove 52. The triangular abutment 341 is fixed to one end of the insert plate 349 and engages in the limiting groove 52 of the transparent cover 5, restricting or releasing the position of the transparent cover 5. Each of the triangular abutments 341 has a locking block 348 fixedly connected to the end away from the insert plate 349. The locking block 348 is fixed to the end of the triangular abutment 341 away from the insert plate 349, enhancing the locking stability of the triangular abutment 341 and limiting the opening size of the pair of transparent covers 5. A pair of return springs 53 are provided in the middle of each limiting port 51. The return springs 53 are located in the middle of the limiting port 51, with one end connected to the inner wall of the limiting port 51 and the other end connected to the first rotating block 3 and the second rotating block 4. Releasing the handle causes the transparent cover 5 to return to its closed position. One end of the return spring 53 is fixedly connected to the inner wall of the limiting port 51, and the other end of the return spring 53 is fixedly connected to the corresponding first rotating block 3 and second rotating block 4.

[0028] In addition, such as Figures 1 to 3 As shown, a pulling mechanism is installed on the connecting plate 2, which is activated by pressing the handle 1 to drive the actuation mechanism. The pulling mechanism includes a conical block 346 located in the middle of one end of the handle 1. The conical block 346 is located in the middle of one end of the handle 1 and moves after being pressed by the arc groove 12 of the clamping block 11, thereby driving the H-shaped sliding plate 347 and the pull rope 345. One end of the conical block 346 is fixedly connected to an H-shaped sliding plate 347 that holds a pair of connecting plates 2. Each connecting plate 2 has a through hole 343, and a rotating rod 344 is rotatably connected inside the through hole 343. The rotating rod 344 is rotatably connected inside the through hole 343, and its groove holds the insert plate 349, assisting the pull rope in pulling the insert plate. The middle of each rotating rod 344 has a groove that holds the insert plate 349. The groove is the position that restricts the sliding of the pull rope 345 and prevents it from sliding left and right inside the through hole 343. Each connecting plate 2 is equipped with a pull rope 345, which connects the conical block 346 and the insert plate 349, transmitting the pulling force of the conical block 346 and pulling the insert plate 349 to slide. One end of the pull rope 345 is fixedly connected to the corresponding insert plate 349, and the other end of the pull rope 345 moves through the through hole 343 and is fixedly connected to the conical block 346.

[0029] It is worth noting that, such as Figure 3As shown, a clamping block 11 is fixedly connected to one end of the handle 1 near the connecting plate 2. The clamping block 11 is fixed to one end of the handle 1 near the connecting plate 2, and its arc-shaped groove 12 is used to abut against the conical block 346. The end of the clamping block 11 away from the handle 1 is provided with an arc-shaped groove 12 that abuts against the conical block 346. The arc-shaped groove 12 is formed on the clamping block 11, contacts the conical block 346, and guides its movement.

[0030] Furthermore, such as Figure 1 and Figure 4 As shown, a pair of clamping plates 7 are fixedly connected to the outer walls of both sides of the first rotating block 3 and the second rotating block 4 to clamp the transparent cover 5. The clamping plates 7 are fixed to both sides of the first rotating block 3 and the second rotating block 4, clamping the transparent cover 5 and guiding its movement. The middle of each clamping plate 7 is provided with multiple ball bearings 71 arranged in a linear pattern. The ball bearings 71 are fixed to both sides of the first rotating block 3 and the second rotating block 4, clamping the transparent cover 5 and guiding its movement.

[0031] In this embodiment, when using the anti-scalding device of the heat-sealing packaging machine, pressing a pair of handles 1 causes the arc-shaped groove 12 of the clamping block 11 to abut against the conical block 346, causing it to drive the H-shaped sliding plate 347 to lock onto a pair of connecting plates 2. The conical block 346 also drives a pair of pull ropes 345 to pull the insert plate 349 to slide within the sleeve 342. The triangular abutment 341 at one end of the insert plate 349 then abuts against the limiting groove 52 of the transparent cover 5, causing the pair of transparent covers 5 to open due to the clamping of the clamping plate 7. This exposes the heat-sealing plate 6 for sealing. When the handles 1 are released, the return spring 53 contracts, the transparent cover 5 closes again, and the triangular abutment 341 re-engages into the limiting groove 52, preventing the operator from touching the heat-sealing plate 6 and thus providing anti-scalding protection during operation. The ball bearings 71 on the clamping plate 7 can reduce friction when the transparent cover 5 moves. The transparent cover 5 is fitted onto the first rotating block 3 and the second rotating block 4 through the limiting port 51 to achieve stable opening and closing action.

[0032] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
