Abstract
Description
Technical Field
[0001] This utility model relates to the field of foam board cutting, and in particular to a polyethylene foam board cutting device with adjustable cutting size. Background Technology
[0002] Polyethylene foam is made primarily of polyethylene resin, with the addition of foaming agents, crosslinking agents, and other additives. It is a very important cushioning material. When using polyethylene foam boards, their shape needs to be processed according to requirements, and they need to be cut into structures that meet the requirements.
[0003] When cutting polyethylene foam boards, heating wires are generally used for heating and cutting. Pre-drawing the cutting line is cumbersome, and the foam board lacks auxiliary support during cutting, making it prone to deformation under stress, which affects the quality of the cut and is not conducive to the cutting and processing of polyethylene foam boards. Utility Model Content
[0004] In view of this, the present invention provides a polyethylene foam board cutting device with adjustable cutting size. The main technical problem to be solved is that the cutting size of the polyethylene foam board can be adjusted during cutting, while the polyethylene foam board is supported at the same time.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a polyethylene foam board cutting device with adjustable cutting size, comprising a base plate, a first movable groove formed on the surface of the base plate, a first movable block movably connected inside the first movable groove, a rotating plate movably connected to the top of the first movable block, a cutting groove formed on the surface of the rotating plate, a scale fixedly connected to the side of the rotating plate, a second movable groove formed on the lower surface of the rotating plate, a second movable block movably connected inside the second movable groove, a pressure plate fixedly connected to the top of the second movable block, the pressure plate being located above the rotating plate, a fixing frame fixedly connected to the upper surface of the base plate, the fixing frame having a "7" shaped structure, and a heating wire fixedly connected between the fixing frame and the base plate.
[0006] By adopting the above technical solution, when using the device, the polyethylene foam board to be cut is placed on the rotating plate, the position of the pressure plate is adjusted, and the cutting size of the polyethylene foam board can be determined according to the scale on the side of the rotating plate. Then, the rotating plate is pushed towards the heating wire to complete the cutting of the polyethylene foam board. By rotating the rotating plate and adjusting its angle, the polyethylene foam board can be made to contact the heating wire at an angle, which increases the contact area between the polyethylene foam board and the heating wire. This allows the upper and middle areas of the heating wire to also contact the polyethylene foam board, making full use of the heat from the upper and middle areas of the heating wire, improving the cutting efficiency of the polyethylene foam board, and avoiding prolonged use of the lower heating wire for cutting, which can cause local overheating of the heating wire, excessive melting of the foam, and the formation of "molten material adhesion," resulting in stringing or burrs during cutting.
[0007] As a further description of the above technical solution:
[0008] A connecting block is fixedly connected to the top of the first movable block, and the bottom of the rotating plate is mounted on the connecting block by connecting screws.
[0009] By adopting the above technical solution, the rotating plate can rotate around the connecting block to adjust the angle. After the adjustment is completed, the rotating plate is locked and fixed by the connecting screws.
[0010] As a further description of the above technical solution:
[0011] A baffle is fixedly connected to the outer surface of the rotating plate, and the baffle is perpendicular to the upper surface of the rotating plate.
[0012] By adopting the above technical solution, the bottom of the polyethylene foam board is supported.
[0013] As a further description of the above technical solution:
[0014] The lower surface of the rotating plate is fixedly connected to a foot, which is located above the cutting groove.
[0015] By adopting the above technical solution, it is easy to place the rotating plate horizontally for use.
[0016] As a further description of the above technical solution:
[0017] The heating wire is located inside the cutting groove.
[0018] By adopting the above technical solution, it is convenient to cut polyethylene foam boards with heating wire.
[0019] As a further description of the above technical solution:
[0020] The pressure plate is located to the right of the heating wire, and the upper surface of the pressure plate is marked with scale markings.
[0021] By adopting the above technical solution, it is easy to determine the cutting dimensions of polyethylene foam boards.
[0022] By employing the above technical solution, the polyethylene foam board cutting equipment with adjustable cutting size of this utility model has at least the following beneficial effects:
[0023] 1. Compared with the prior art, this adjustable cutting size polyethylene foam board cutting equipment allows the polyethylene foam board to be cut to be placed on a rotating plate, the position of the pressure plate to be adjusted, and the cutting size of the polyethylene foam board to be determined according to the scale on the side of the rotating plate. Then, the rotating plate is pushed towards the heating wire to complete the cutting of the polyethylene foam board.
[0024] 2. Compared with existing technologies, this adjustable-size polyethylene foam board cutting equipment, by rotating the rotating plate and adjusting its angle, allows the polyethylene foam board to contact the heating wire at an angle. This increases the contact area between the polyethylene foam board and the heating wire, ensuring that the upper and middle areas of the heating wire also contact the polyethylene foam board. This fully utilizes the heat from the upper and middle areas of the heating wire, improving the cutting efficiency of the polyethylene foam board. It also avoids prolonged use of the lower heating wire for cutting, which can cause localized overheating of the heating wire, resulting in excessive melting of the foam and the formation of "molten material adhesion," leading to stringing or burrs during cutting.

[0031] Reference Figure 1-4 This utility model provides an adjustable-size polyethylene foam board cutting device, comprising a base plate 1, a first movable groove 2 on the surface of the base plate 1, a first movable block 3 movably connected inside the first movable groove 2, a rotating plate 5 movably connected to the top of the first movable block 3, a connecting block 4 fixedly connected to the top of the first movable block 3, the bottom of the rotating plate 5 being mounted on the connecting block 4 by connecting screws, the rotating plate 5 being able to rotate around the connecting block 4 to adjust its angle, and after adjustment, the rotating plate 5 being locked and fixed by connecting screws; a cutting groove 7 on the surface of the rotating plate 5, a scale 8 fixedly connected to the side of the rotating plate 5, a second movable groove 9 on the lower surface of the rotating plate 5, a second movable block 10 movably connected inside the second movable groove 9, a pressure plate 11 fixedly connected to the top of the second movable block 10, the pressure plate 11 being located above the rotating plate 5, and a fixing frame 13 fixedly connected to the upper surface of the base plate 1, the fixing frame 13 having a "7"-shaped structure. A heating wire 14 is fixedly connected between the fixed frame 13 and the base plate 1. In use, the polyethylene foam board to be cut is placed on the rotating plate 5, the position of the pressure plate 11 is adjusted, and the cutting size of the polyethylene foam board can be determined according to the scale 8 on the side of the rotating plate 5. Then, the rotating plate 5 is pushed towards the heating wire 14 to complete the cutting of the polyethylene foam board. By rotating the rotating plate 5 and adjusting the angle of the rotating plate 5, the polyethylene foam board can be made to contact the heating wire 14 in an inclined direction, which can increase the contact area between the polyethylene foam board and the heating wire 14, so that the middle and upper areas of the heating wire 14 can also contact the polyethylene foam board. This can make full use of the heat of the middle and upper areas of the heating wire 14, improve the cutting efficiency of the polyethylene foam board, and also avoid prolonged use of the lower heating wire 14 for cutting, which can cause the heating wire 14 to overheat and melt the foam excessively, forming "molten material adhesion", which will produce stringing or burrs during cutting.

The baffle 6 is perpendicular to the upper surface of the rotating plate 5 and serves to support the bottom of the polyethylene foam board. A foot 12 is fixedly connected to the lower surface of the rotating plate 5. The foot 12 is located above the cutting groove 7, which facilitates the horizontal placement of the rotating plate 5.
[0033] The heating wire 14 is located inside the cutting groove 7, which facilitates the cutting of the polyethylene foam board by the heating wire 14. The pressure plate 11 is located to the right of the heating wire 14. The upper surface of the pressure plate 11 is marked with scale marks to facilitate the determination of the cutting size of the polyethylene foam board.
[0034] Working principle: When using, place the polyethylene foam board to be cut on the rotating plate 5, adjust the position of the pressure plate 11, and determine the cutting size of the polyethylene foam board according to the scale 8 on the side of the rotating plate 5. Then push the rotating plate 5 towards the heating wire 14 to complete the cutting of the polyethylene foam board.
