Description

Technical Field

[0001] This utility model relates to the field of paper gasket pressing and molding technology, specifically to a pressing and molding structure for a pressure-resistant paper gasket. Background Technology

[0002] During packaging and transportation, compression-resistant paper pads can effectively absorb and disperse external impact forces, reducing the risk of damage to items due to collisions and vibrations. For example, in the packaging of fragile items such as electronic products and glass products, they can play a good cushioning and protection role. They need to be pressed and formed by a compression-resistant paper pad forming device to give the paper pads high compression resistance and the ability to withstand a certain weight of pressure without deformation.

[0003] For example, Chinese patent application CN216658358U shows a technical solution including a crossbeam and a column. The column and the crossbeam are welded to form a rectangular frame. A base plate is welded between the bottom crossbeams of the rectangular frame. A forming mold is fixed in the middle of the base plate. A partition plate is provided above the forming mold and inside the frame. A top cover plate is welded to the top crossbeam of the rectangular frame. A double cylinder is provided in the middle of the top cover plate. A horizontal plate is fixedly connected to the output end of the double cylinder. The horizontal plate has four equally spaced threaded holes, and a pressing mechanism is threadedly connected to each threaded hole. This technical solution integrates a guide bushing inside the partition plate and connects it to the center of the pressing rod, which limits the left and right swaying of the pressing rod during the pressing process. This allows the pressing mechanism to achieve precise alignment with the forming area, improving the pressing efficiency and other technical effects.

[0004] However, the following problems still exist in this technical solution: the mold diameter is limited to one type of compression-resistant paper gasket, which restricts its use. Utility Model Content

[0005] The purpose of this invention is to provide a compression molding structure for a pressure-resistant paper gasket. The pressing plate and the holding cylinder can be disassembled by a disassembly mechanism for easy replacement, so as to facilitate the compression molding of paper gaskets of different diameters. The paper gasket can also be pushed out of the bottom plate by a feeding mechanism for easy collection, thereby solving the above-mentioned shortcomings in the technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a compression molding structure for a pressure-resistant paper gasket, comprising a base plate, a pressing plate on the top of the base plate, two holding cylinders on the top of the base plate, and a disassembly mechanism on the top of the base plate for facilitating the disassembly of the pressing plate and the holding cylinders.

[0007] Preferably, the disassembly mechanism includes two support plates located on the top of the base plate, with the two support plates respectively located on one side of the two containers. Both the support plates and the containers have two first threaded holes, and the two connected first threaded holes are internally threaded with the same first bolt for disassembling the pressing plate.

[0008] Preferably, the top of the base plate is provided with a lifting mechanism for driving the pressing plate to rise and fall. The lifting mechanism includes a support frame located on the top of the base plate, a threaded cylinder passing through the support frame, the threaded cylinder being movably connected to the support frame via a bearing, and a threaded rod being threadedly connected inside the threaded cylinder. The pressing plate is located at the bottom of the threaded rod and is used to drive the pressing plate to rise and fall.

Gears are provided through both the rotating shaft and the outside of the threaded cylinder, and the two gears mesh with each other. The bottom end of the rotating shaft passes through the support frame and extends out of the bottom of the support frame. A first motor is fixedly provided at the bottom end of the rotating shaft for driving the threaded cylinder to rotate.

[0010] Preferably, a limiting cylinder is fixedly provided on the top of the pressing plate. The limiting cylinder is adapted to the bottom end of the threaded rod. A second threaded hole is provided on both the limiting cylinder and the threaded rod. The two connected second threaded holes are internally threaded with the same second bolt for disassembling the container.

[0011] Preferably, the top of the base plate is provided with a feeding mechanism for feeding the pressed paper pads. The feeding mechanism includes a fixed plate on the support frame, two electric push rods are provided through the fixed plate, the front ends of the two electric push rods are fixed with the same push plate, and a feeding plate is fixed on the front side of the base plate for feeding the pressed paper pads.

[0012] Preferably, the top of the base plate is provided with a moving mechanism for moving the two containers. The moving mechanism includes a bidirectional threaded rod inside the base plate. Both ends of the bidirectional threaded rod are threadedly connected to limit plates. The top of the limit plates passes through the base plate and extends beyond the top of the base plate. The top of the limit plates is fixedly connected to the bottom of the containers. One end of the bidirectional threaded rod passes through the base plate and extends beyond one side of the base plate. The bidirectional threaded rod is movably connected to the base plate through a bearing. A second motor is fixedly provided at one end of the bidirectional threaded rod for moving the two containers.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. Rotate the first bolt to unscrew it from the first threaded hole, then pull the container to remove it from the support plate. Next, rotate the second bolt to unscrew it from the second threaded hole, and pull the pressing plate to remove it from the bottom of the threaded rod. The pressing plate and the container can be disassembled through the disassembly mechanism for easy replacement, so as to press and form paper gaskets of different diameters.

[0015] 2. Turn on the electric push rod and use it to move the push plate. The movement of the push plate can push the pressed paper pads out from the bottom plate. The pressed paper pads can slide out along the feed plate for easy collection. Attached Figure Description

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figure 1-6 The compression molding structure of a compression-resistant paper gasket shown includes a base plate 1, a pressing plate 2 on the top of the base plate 1, two holding cylinders 3 on the top of the base plate 1, and a disassembly mechanism 4 on the top of the base plate 1 to facilitate the disassembly of the pressing plate 2 and the holding cylinders 3.

[0030] like Figure 5 As shown, the top of the base plate 1 is provided with a lifting mechanism 5 that drives the pressing plate 2 to rise and fall. The lifting mechanism 5 includes a support frame 501 located on the top of the base plate 1. A threaded cylinder 502 is provided through the support frame 501. The threaded cylinder 502 is movably connected to the support frame 501 through a bearing. A threaded rod 503 is threadedly connected inside the threaded cylinder 502. The pressing plate 2 is located at the bottom of the threaded rod 503.

[0031] like Figure 5 As shown, the top of the support frame 501 is movably connected to the rotating shaft 504 via a bearing. Gears 505 are provided through the outside of both the rotating shaft 504 and the threaded cylinder 502. The two gears 505 mesh with each other. The bottom end of the rotating shaft 504 passes through the support frame 501 and extends out of the bottom of the support frame 501. A first motor 506 is fixedly provided at the bottom end of the rotating shaft 504.

[0032] First, place the paper pad inside the two container cylinders 3. Then, start the first motor 506. The first motor 506 can drive the rotating shaft 504 to rotate. Under the action of the two gears 505, the rotating shaft 504 can drive the threaded cylinder 502 to rotate. The rotation of the threaded cylinder 502 can drive the threaded rod 503 to move downward. The threaded rod 503 is used to move the pressing plate 2 into the two container cylinders 3. The pressing plate 2 is used to press and shape the paper pad.

[0033] like Figure 3As shown, the top of the base plate 1 is provided with a moving mechanism 7 that drives the two container cylinders 3 to move.

The top of the limit plates 702 passes through the base plate 1 and extends out of the top of the base plate 1. The top of the limit plates 702 is fixedly connected to the bottom of the container cylinders 3.

The bidirectional threaded rod 701 is movably connected to the base plate 1 through a bearing. A second motor 703 is fixedly provided at one end of the bidirectional threaded rod 701.

[0034] Start the second motor 703, which drives the bidirectional threaded rod 701 to rotate. The rotation of the bidirectional threaded rod 701 can drive the limiting plate 702 to move. The limiting plate 702 can drive the container cylinder 3 to move, separating the two container cylinders 3, so that the pressed paper pad falls to the top of the base plate 1.

[0035] like Figure 6 As shown, the bottom plate 1 is provided with a feeding mechanism 6 for feeding the pressed paper pads. The feeding mechanism 6 includes a fixed plate 601 on the support frame 501. Two electric push rods 602 are provided through the fixed plate 601.

[0036] Turn on the electric push rod 602, and use the electric push rod 602 to drive the push plate 603 to move. The movement of the push plate 603 can push the pressed paper pad out from the base plate 1. The pressed paper pad can slide out along the feed plate 604 for easy collection.

[0037] like Figure 4 , 5 As shown, the disassembly mechanism 4 includes two support plates 401 on the top of the base plate 1. The two support plates 401 are respectively located on one side of the two containers 3. The support plates 401 and the containers 3 each have two first threaded holes 402. The two connected first threaded holes 402 are threaded with the same first bolt 403. The top of the pressing plate 2 is fixedly provided with a limiting cylinder 404. The limiting cylinder 404 is adapted to the bottom end of the threaded rod 503. The limiting cylinder 404 and the threaded rod 503 each have second threaded holes 405. The two connected second threaded holes 405 are threaded with the same second bolt 406.

[0038] Rotate the first bolt 403 to unscrew it from the first threaded hole 402, then pull the container 3 to remove it from the support plate 401. Next, rotate the second bolt 406 to unscrew it from the second threaded hole 405, and pull the pressing plate 2 to remove it from the bottom of the threaded rod 503. The pressing plate 2 and the container 3 can be disassembled through the disassembly mechanism 4 for easy replacement, so as to press and form paper gaskets of different diameters.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
