However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example 1

[0027] Reference Figures 1 to 5 , is the first embodiment of the utility model, which provides a production and cutting device for high-strength cover rubber of flame-retardant conveyor belts for coal mines, comprising:

[0028] The support mechanism 100 includes a hollow shell 101, and brake wheels 102 are fixed to the four corners of the bottom of the hollow shell 101 by bolts;

[0029] A clamping mechanism 200 is fixedly provided in the inner cavity of the hollow shell 101 , and a cutting mechanism 300 used in conjunction with the clamping mechanism 200 is fixedly installed on the top of the hollow shell 101 .

[0030] Specifically, the clamping mechanism 200 includes a first motor 201 adapted to be mounted on the bottom of the hollow housing 101 , and an output end of the first motor 201 extends to the inner cavity of the hollow housing 101 .

[0031] Among them, a plurality of elliptical holes are opened at the bottom of the inner surface of the hollow shell 101 to discharge the waste generated during the cutting process without causing any impact on the bidirectional screw rod 203.

[0032] Furthermore, a first bevel gear 202 is fixedly installed at the output end of the first motor 201, a bidirectional screw rod 203 is rotatably connected to the inner wall of the hollow shell 101, a second bevel gear 204 is fixedly sleeved in the middle of the outer surface of the bidirectional screw rod 203, and a symmetrical long rod 205 is threadedly connected to the outer surface of the bidirectional screw rod 203.

[0033] Among them, the second bevel gear 204 is engaged with the first bevel gear 202, and the long rod 205 is located in the inner cavity of the hollow shell 101. The two long rods 205 are driven by the threads on the outer side of the bidirectional screw rod 203 to move toward each other evenly, thereby stabilizing the conveyor belt in the middle part of the top of the hollow shell 101 for better cutting of the conveyor belt.

[0034] Furthermore, a number of connecting blocks 206 are fixedly installed on the upper surface of the long rod 205, and the top of the connecting block 206 is fixedly connected to the clamping plate 207 by bolts. A number of hollow plates 208 are fixedly provided at the bottom of the inner surface of the hollow shell 101 and are evenly distributed at the bottom of the inner surface of the hollow shell 101. Holes 209 are opened on the upper surface of the hollow shell 101.

[0035] The connecting blocks 206 are evenly arranged on the top of the long rods 205 , the long rods 205 are slidably connected to the plurality of long rods 205 , and the connecting blocks 206 are slidably connected to the holes 209 .

[0036] When in use, the conveyor belt to be cut is placed in the middle part relative to the cutting mechanism 300 and the hollow shell 101. At this time, the first motor 201 is controlled to run, and the output end of the first motor 201 drives the first bevel gear 202 to rotate, and the first bevel gear 202 drives the second bevel gear 204 to rotate, and the second bevel gear 204 drives the bidirectional screw rod 203 to rotate on the inner wall of the hollow shell 101. With the assistance of multiple hollow plates 208, the bidirectional screw rod 203 drives the two symmetrical long rods 205 to move toward each other through the outer thread, and the long rods The rod 205 drives the multiple connecting blocks 206 on its top to move in the hole 209, thereby driving the clamping plates 207 to move. Since the clamping plates 207 are distributed at the four corners of the top of the hollow shell 101, and every two are symmetrical, with the cooperation of the multiple clamping plates 207, the conveyor belt located at the top of the hollow shell 101 is clamped, so that the conveyor belt and the cutting mechanism 300 form a vertical relationship. At this time, the brake wheels 102 at the four corners of the bottom of the hollow shell 101 are braked, and finally the conveyor belt is cut by the action of the cutting mechanism 300.

[0037] In summary, through the action of the clamping mechanism 200, the conveyor belt can be fixed and maintained in a vertical state with the cutting mechanism 300, so that the incision is ensured to be flush during the cutting process, which facilitates the splicing of the conveyor belt, thereby improving the efficiency of subsequent conveyor belt connection. Under the action of the cutting mechanism 300, the conveyor belt with a harder texture can be cut, thereby improving the efficiency of conveyor belt cutting.

[0038] Example 2

[0039] Reference Figure 4 and 5 , which is the second embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a cutting mechanism 300 that can cut a conveyor belt with a relatively hard texture.

[0040] Specifically, the cutting mechanism 300 includes fixed side plates 301 fixedly installed on both sides of the upper surface of the hollow shell 101 and symmetrically distributed. A second motor 302 is adapted to be installed on one side of the fixed side plate 301. The output end of the second motor 302 is fixedly connected to a one-way screw rod 303. The outer surface of the one-way screw rod 303 is threadedly connected to a slider 304. A slide rod 305 is fixedly installed on one side of the fixed side plate 301.

[0041] Among them, the one-way screw rod 303 is rotatably connected to the inside of the fixed side plate 301, the sliding rod 305 is fixedly installed on the opposite side of the two fixed side plates 301 and is symmetrically distributed, the slider 304 is slidably connected to the outside of the sliding rod 305, and the slider 304 is slidably connected to the outside of the two sliding rods 305. Therefore, under the action of the two sliding rods 305, when the slider 304 moves, the slider 304 is kept moving stably, thereby ensuring that the incision is flush.

[0042] Furthermore, a telescopic cylinder 306 is adapted to be installed on the lower surface of the slider 304, and the output end of the telescopic cylinder 306 is fixedly connected to a fixed plate 307 by bolts. A cutting motor 308 used in conjunction with the clamping mechanism 200 is adapted to be installed on the lower surface of the fixed plate 307, and a protective cover 309 is fixedly provided on one side of the fixed plate 307.

[0043] Among them, the protective cover 309 is located on the top of the cutting piece at the output end of the cutting motor 308, and the protective cover 309 is located on the top of the blade at the output end of the cutting motor 308, so during the cutting process, it prevents debris from splashing into the mouth and nose of the staff, and does not affect the cutting operation of the conveyor belt.

[0044] When in use, after placing the conveyor belt to be cut on the opposite side of the hollow shell 101 and the cutting motor 308, the operation of the cutting motor 308 is controlled first, and the output end of the cutting motor 308 drives the cutting blade on one side to rotate, and then the operation of the second motor 302 is controlled again, and the output end of the second motor 302 drives the one-way screw rod 303 to rotate, and the one-way screw rod 303 drives the slider 304 to move with the assistance of the slide rod 305, first moving the slider 304 to the end away from the second motor 302, and finally controlling the operation of the telescopic cylinder 306, the telescopic cylinder 306 pushes the fixed plate 307 downward, and the fixed plate 307 drives the cutting motor 308 to move, thereby cutting the conveyor belt. After cutting a hole, the second motor 302 is controlled to rotate in the opposite direction, thereby moving the slider 304 to the side of the second motor 302, thereby driving the cutting motor 308 to cut the conveyor belt.

[0045] In summary, through the action of the cutting mechanism 300, the conveyor belt with a harder texture can be cut, thereby reducing the labor intensity of manual labor. Using this mechanism, the conveyor belt can be easily cut to the required length. At the same time, with the cooperation of the clamping mechanism 200, the cutting port can be kept flush, thereby improving the cutting quality of the conveyor belt.
