Technical Field

[0001] The utility model relates to the technical field of cutters, in particular to a cutter device for cutting plastics. Background Art

[0002] Plastic products are a general term for daily and industrial products made of plastic as the main raw material. They include products made from injection molding, blister molding and other processes using plastic as raw materials. Plastic is a type of synthetic polymer material with plasticity. After the plastic products on the production line are formed, they need to be cut into the required shape.

[0003] Among them, a cutter is required for cutting plastics. The cutters used in the prior art are all cut in the horizontal or vertical direction. The inclination angle of the cutter cannot be changed during the cutting process, which results in the inability to smoothly complete the arc cutting during cutting. In addition, due to the long cutting surface of the cutter, it will be impossible to effectively complete the fine cutting during the cutting process, for example, a shorter incision. In the case where the inclination angle of the cutter cannot be changed, it is impossible to effectively cut into a shorter incision. Therefore, there is an urgent need for a cutter device for cutting plastics and facilitating the change of the inclination angle of the cutter. Utility Model Content

[0020] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0021] Please refer to Figure 1-Figure 6 As shown, the utility model provides a cutter device for cutting plastics, including a cutter body 1, on which a mounting mechanism is detachably provided, a square block 121 is fixedly provided on the top surface of the mounting mechanism, and a power mechanism for driving the cutter body 1 to slide up and down is detachably provided on the periphery of the square block 121.

[0022] The power mechanism includes a telescopic adjustment plate 2 and a limit sleeve 221. The limit sleeve 221 is installed on the periphery of the square block 121 through positioning bolts. The limit sleeve 221 is movably connected to the bottom surface of one side of the telescopic adjustment plate 2.

[0023] A fixing block 21 is fixedly arranged on the top surface of the telescopic adjustment plate 2 corresponding to the upper part of the cutter body 1 , and an adjustment mechanism for driving the limiting sleeve block 221 to be in an inclined state is arranged between the side surface of the fixing block 21 and the side surface of the limiting sleeve block 221 .

[0024] In this case, a detachable mounting mechanism is provided on the cutter body 1, which facilitates the disassembly and assembly of the cutter body 1 itself for replacement, and a square block 121 is provided on the top surface of the mounting mechanism, which can be driven by a power mechanism to slide the square block 121 up and down, thereby realizing the up and down movement of the cutter body 1, which is convenient for cutting the plastic below.

[0025] By setting the telescopic adjustment plate 2 and the limiting sleeve block 221, it is convenient to adjust the distance of the cutter body 1 so as to cut different positions of the plastic. At the same time, a fixed block 21 is fixedly arranged on the top surface of the telescopic adjustment plate 2, and an adjustment mechanism is arranged between the fixed block 21 and the limiting sleeve block 221. The adjustment mechanism can drive the limiting sleeve block 221 to swing, so that the limiting sleeve block 221 is in an inclined state, so as to make one corner of the cutter body 1 contact with the plastic. At this time, the plastic is cut through one corner of the cutter body 1, which can complete the refined cutting work and cut a shorter incision, thereby improving the application range of the cutter and improving the use efficiency.

[0026] Among them, by adjusting the inclination of the cutter body 1, it is convenient to carry out fine processing of plastic and complete the engraving process, and the limiting sleeve block 221 and the square block 121 are fixed by positioning bolts to facilitate the disassembly of the cutter and convenient replacement with different types of cutters.

[0027] like Figure 1 and Figure 2As shown, the mounting mechanism includes a mounting plate 12, a screw and a nut. The mounting plate 12 is an L-shaped structure. One end of the screw is fixedly connected to the mounting plate 12, and the other end of the screw passes through the cutter body 1 and is threadedly connected to the nut. The square block 121 is fixedly set on the top surface of the mounting plate 12.

[0028] The cutter body 1 is installed on the mounting plate 12 by passing a screw through the cutter body 1 , and a hole for the screw to pass through is provided near the top surface of the cutter body 1 , and then a nut is threadedly connected to the outer periphery of the other end of the screw.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, the cutter body 1 is a square structure, and the side and bottom surfaces are cutters. A cutter groove 11 is provided on the top surface of the cutter body 1. A U-shaped heating wire 13 is inserted into the inner wall of the cutter groove 11 near the cutter. A cover plate is provided on the periphery of the heating wire 13 and is clamped on the top of the inner wall of the cutter groove 11.

[0030] The electric heating wire 13 is provided to heat the cutter body 1, so that the cutter body 1 can effectively soften the plastic when cutting the plastic, thereby ensuring the cutting stability, reducing the possibility of plastic breaking and bursting during forced cutting, and effectively ensuring that the plastic is cut into the desired shape.

[0031] The side and bottom surfaces of the cutter body 1 are arranged as cutters so as to cut the plastic during horizontal movement, thereby being able to cut the plastic at multiple angles and improving the cutting range.

[0032] like Figure 1 and Figure 2 As shown, the power mechanism also includes a hydraulic rod 23, which is fixedly arranged on the bottom surface of the telescopic end of the telescopic adjustment plate 2, and a power device for driving the hydraulic rod 23 to move horizontally and rotate is arranged at the bottom end of the hydraulic rod 23.

[0033] Among them, there are many power devices for driving the equipment to move horizontally and rotate in the prior art, so they are not drawn in the drawings in this application document. By driving the hydraulic rod 23, the plastic can be cut at various positions at any time.

[0034] like Figure 5 and Figure 6As shown, the adjustment mechanism includes a connecting support plate 3, a gear 31 and a driving motor 311. The connecting support plate 3 is a U-shaped structure, and the length of one end is smaller than the length of the other end. One end of the connecting support plate 3 is rotatably connected to the side wall of the limiting sleeve 221 through a rotating shaft, and the other end of the connecting support plate 3 is inserted into and passes through the fixed block 21. The top surface of the long end of the connecting support plate 3 is provided with a tooth opening that meshes with the gear 31. The gear 31 is rotatably set on the top surface of the fixed block 21. The gear 31 is fixedly connected to the power output end of the driving motor 311, and the driving motor 311 is fixedly set on the top surface of the fixed block 21.

[0035] An adjusting bead 22 is rotatably provided on the bottom surface of the limiting sleeve block 221 and one side of the telescopic adjusting plate 2 .

[0036] By starting the driving motor 311, the gear 31 can be driven to rotate, and the gear 31 is meshed with the toothed opening on the connecting support plate 3. The rotation of the gear 31 can drive the connecting support plate 3 to move horizontally. At this time, one end of the connecting support plate 3 can pull or push the limiting sleeve 221 to move. Under the limiting action of the adjusting bead 22, one end of the connecting support plate 3 is rotatably connected to the limiting sleeve 221 through a rotating shaft, so that the limiting sleeve 221 can swing up and down in a horizontal position, so as to adjust the inclination angle of the limiting sleeve 221, thereby changing the inclination angle of the cutter body 1, so as to carry out fine processing of the plastic, and cooperate with the hydraulic rod 23 and the power device to effectively engrave and process the plastic, thereby improving the application range of cutting.
