[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. A conveyor belt cutting machine disclosed by the present utility model can effectively avoid the situation of conveyor belt sliding or loosening during the cutting process by setting the clamping device, improving the clamping stability; the distance between the two clamping devices at both ends of the guiding beam limits the width of the conveyor belt.

Detailed implementation manner

[0030] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments provided by the present utility model without creative efforts fall within the protection scope of the present utility model.

[0031] An embodiment of the present utility model provides a conveyor belt cutting machine, refer to Figures 1 to 6As shown in the figure, the cutting machine at least includes a frame 1 and a plurality of guide beams 2. The guide beams 2 are arranged on the frame 1. At both ends of each guide beam 2, a clamping device 3 is respectively provided. The clamping device 3 reciprocates along the length direction of the guide beam 2. The clamping device 3 includes a sliding member 301, a fixing member 303, a first pressing plate 304 and a driving assembly 305. One end of the sliding member 301 is mounted on the guide beam 2, and a connecting plate 302 is provided at the other end of the sliding member 301. One end of the fixing member 303 is connected to the sliding member 301, and the other end of the fixing member 303 is connected to the guide beam 2. The first pressing plate 304 is arranged opposite to the guide beam 2. The driving assembly 305 is rotatably connected to the connecting plate 302. One end of the driving assembly 305 is connected to the first pressing plate 304, and the driving assembly 305 drives the first pressing plate 304 to reciprocate up and down. Based on the synergistic effect of the clamping device 3 and the guide beam 2, the clamping device 3 on the guide beam 2 can adapt to conveyor belts of different widths through the movement of the sliding member 301, and the sliding member 301 is fixed at a suitable position through the fixing member 303 to achieve width adjustment. The driving assembly 305 drives the first pressing plate 304 to move up and down by rotation, so as to adjust the height between the first pressing plate 304 and the guide beam 2 to adapt to conveyor belts of different thicknesses, ensuring that the conveyor belt can be firmly clamped stably during the cutting process. By setting the clamping device 3, the sliding or loosening of the conveyor belt during the cutting process is effectively avoided, greatly improving the stability of clamping. By adjusting the clamping device 3, conveyor belts of different widths and thicknesses can be adapted to ensure the smoothness during the cutting process, thereby avoiding the problem of skewed cutting seams during the cutting process and improving the cutting accuracy and quality.

[0032] In some embodiments, as Figure 1 shown, the number of the guide beams 2 is 2, which are respectively arranged on both sides of the frame 1. At both ends of each guide beam 2, a clamping device 3 is respectively provided, so that the four clamping devices 3 respectively clamp the positions of the four corners of the conveyor belt, making the conveyor belt clamped more firmly.

[0033] Furthermore, the conveyor belt cutting machine further includes a moving device 4. The moving device 4 is slidably connected to the frame 1. The moving device 4 includes a vehicle body 401, a speed reducer 402, a driving sprocket 403, a driven sprocket 404, and a rack 407. The speed reducer 402 is arranged on the vehicle body 401, and the driving sprocket 403 is connected to the speed reducer 402. The driven sprocket 404 is connected to the driving sprocket 403, and the driven sprocket 404 is arranged on a driven shaft 405. Gears 406 are provided at both ends of the driven shaft 405. The rack 407 is arranged on the frame 1, and the rack 407 meshes with the gears 406. Through the cooperation of the vehicle body 401, the gears 406, the rack 407, the driving sprocket 403, and the driven sprocket 404, the vehicle body 401 can reciprocate along the length direction of the frame 1. The speed reducer 402 drives the driving sprocket 403 to rotate, thereby driving the driven sprocket 404, the driven shaft 405, and the gears 406 to rotate. The meshing of the gears 406 with the rack 407 enables the vehicle body 401 to move on the frame 1, so that the cutting device 5 can move along the width direction of the conveyor belt to achieve intermittent cutting. The design of the moving device 4 enables the conveyor belt cutting machine to efficiently perform the cutting operation. Through the reciprocating movement of the moving device 4, the cutting of the conveyor belt can be quickly and accurately completed, greatly improving the work efficiency. In addition, the structural design of the moving device 4 ensures the moving stability of the cutting device 5 and further improves the cutting accuracy.

[0034] Furthermore, the conveyor belt cutting machine further includes a cutting device 5. The cutting device 5 is arranged on the moving device 4, and the moving device 4 drives the cutting device 5 to reciprocate. The cutting device 5 includes a shearing machine bed body 501, a fixed tool holder 502, a moving tool holder 504, and a first hydraulic cylinder 506. The fixed tool holder 502 is arranged below the shearing machine bed body 501 and is at the same height as the guiding beam 2. A fixed tool 503 is provided on the fixed tool holder 502. The moving tool holder 504 is arranged opposite to the fixed tool holder 502, and a moving tool 505 is provided on the moving tool holder 504. The piston rod of the first hydraulic cylinder 506 is connected to the moving tool holder 504, and the first hydraulic cylinder 506 drives the moving tool holder 504 to reciprocate up and down. Driven by the moving device 4, the cutting device 5 reciprocates in the width direction of the conveyor belt to achieve cutting along the width direction of the conveyor belt. The fixed tool holder 502 is at the same height as the guiding beam 2 to ensure the flatness during cutting. The first hydraulic cylinder 506 drives the moving tool holder 504 to move the moving tool holder 504 up and down, so as to perform cutting by using the shearing force between the fixed tool 503 and the moving tool 505. By providing a hydraulically driven cutting device 5, the problem of insufficient shearing force of traditional mechanical cutters during the cutting process is solved. The hydraulic cylinder provides a strong shearing force, ensuring that the cut surface is smooth and neat without adhesion phenomenon, greatly improving the quality and efficiency of conveyor belt cutting.

[0035] Further, the conveyor belt cutting machine further includes an auxiliary pressing device 6. The auxiliary pressing device 6 is arranged on the cutting device 5. The auxiliary pressing device 6 includes a plurality of second hydraulic cylinders 601 and a second pressing plate 602. The second hydraulic cylinders 601 are arranged on one side of the shearing machine bed 501. The second pressing plate 602 is connected to the piston rods of the plurality of second hydraulic cylinders 601. The plurality of second hydraulic cylinders 601 drive the second pressing plate 602 to move up and down reciprocally. Through the control of the plurality of second hydraulic cylinders 601, the auxiliary pressing device 6 performs an additional pressing process on the conveyor belt during the cutting process. The pressing force provided by the plurality of hydraulic cylinders ensures that the conveyor belt will not drift or displace during the cutting process, thereby keeping the cut surface neat and smooth. The reciprocating up and down movement of the second pressing plate 602 is driven by the second hydraulic cylinders 601 and is synchronized with the cutting process to ensure further improvement of the cutting quality. The setting of the auxiliary pressing device 6 effectively solves the problems of possible drift and uneven cut surface of the conveyor belt during the cutting process. Through secondary pressing, the positioning accuracy during the cutting process and the quality of the cut surface are ensured, making the cutting result more accurate and consistent. In addition, the operation of the auxiliary pressing device 6 is simple, and it can adapt to conveyor belts of different thicknesses and materials, further improving the applicability and operation convenience of the equipment.

[0036] Further, the conveyor belt cutting machine further includes two idler rollers 7, which are respectively arranged on the left and right sides of the frame 1. The idler rollers 7 are arranged at an interval from the guide beam 2 and are located on the side of the guide beam 2 away from the cutting device 5. The setting of the idler rollers 7 not only provides a stable supporting effect, but also effectively prevents the wear problem caused by the contact between the conveyor belt and the guide beam 2 or other components during the conveying process. This design prolongs the service life of the conveyor belt and further improves the smoothness and accuracy during the conveyor belt cutting process, ensuring the cutting quality.

[0037] Further, the driving assembly 305 includes a rotating shaft 3052 and a handwheel 3051. The rotating shaft 3052 is rotatably connected to the connecting plate 302. One end of the rotating shaft 3052 is connected to the first pressing plate 304, and the handwheel 3051 is connected to the other end of the rotating shaft 3052. The driving assembly 305 adjusts the height of the first pressing plate 304 through the cooperation of the rotating shaft 3052 and the handwheel 3051. When the handwheel 3051 rotates through the rotating shaft 3052, the other end of the rotating shaft 3052 moves up and down, thereby pushing the connected first pressing plate 304 to reciprocate up and down relative to the guiding beam 2. In this way, when adjusting the handwheel 3051, the operator can precisely adjust the position of the first pressing plate 304 to adapt to conveyor belts of different thicknesses and ensure the stability of the clamping device 3. This driving assembly 305 has a simple structure and is convenient to operate, enabling the operator to easily adjust the height of the pressing plate 304 by rotating the handwheel 3051. This design enables the conveyor belt cutting machine to quickly adapt to conveyor belts of different thicknesses, ensures stable pressing force during the cutting process, effectively avoids the problem of conveyor belt displacement during the cutting process, and improves the use efficiency and cutting quality of the cutting machine.

[0038] Further, the moving device 4 further includes two guiding brackets 408. The guiding brackets 408 are arranged on the vehicle body 401. Both ends of the driven shaft 405 pass through the two guiding brackets 408 and are connected to two gears 406 respectively. A plurality of guiding wheels 409 are arranged on the guiding brackets 408, and the guiding wheels 409 are in contact with the surface of the rack 407. The moving device 4 realizes the stable operation of the moving device 4 on the rack 1 through the cooperation of the guiding brackets 408 and the guiding wheels 409 arranged on the vehicle body 401. The guiding brackets 408 provide stable support for the driven shaft 405 and the gears 406, preventing them from shifting or shaking during operation. At the same time, the guiding wheels 409 are in contact with the surface of the rack 407, reducing the friction during movement through rolling, enabling the entire moving device 4 to move more smoothly along the rack 1. This design further improves the operation stability and accuracy of the moving device 4. Through the arrangement of the guiding brackets 408, the driven shaft 405 and the gears 406 can maintain accurate orbits during operation, avoiding deviation and vibration, thereby ensuring the accuracy of the movement of the cutting device 5 and the cutting quality. In addition, the use of the guiding wheels 409 reduces friction, lowers the energy consumption and operating noise of the cutting machine, and thus extends the service life of the cutting machine.

[0039] Further, the cutting device 5 further includes a mounting plate 507 and an induction plate 510. The mounting plate 507 is provided at the top of the shearing machine bed 501, and an upper limit switch 508 and a lower limit switch 509 are provided on the mounting plate 507; the induction plate 510 is connected to the moving tool holder 504, and the moving tool holder 504 drives the induction plate 510 to move up and down reciprocally. The cutting device 5 works in cooperation with the induction plate 510 and the limit switches 508 and 509 to control the up and down movement range of the moving tool holder 504. The induction plate 510 triggers the upper limit switch 508 and the lower limit switch 509 as the moving tool holder 504 moves, thereby controlling the action of the hydraulic cylinder 506 to ensure that the moving tool holder 504 reciprocates within a set range. This control method avoids excessive up and down movement of the moving tool holder 504, protects the cutting tool and the conveyor belt being cut, and at the same time ensures the cutting accuracy. By using the upper and lower limit switches 508 and 509 and the induction plate 510, the working range of the cutting device 5 is accurately controlled, avoiding excessive movement or misoperation of the moving tool holder 504, and extending the service life of the equipment. The upper and lower limit switches 508 and 509 ensure the safety and stability during the cutting process, preventing equipment damage or improper cutting that may be caused by the position of the moving tool holder 504 exceeding the predetermined range.

[0040] Further, the shearing angle between the fixed knife 503 and the moving knife 505 is an inclined angle. The shearing angle between the fixed knife 503 and the moving knife 505 is designed as an inclined angle, similar to a scissor structure, which enhances the shearing force and cutting accuracy and ensures that the cut surface is neat and free of adhesion. The scissor-like structure design further improves the cutting accuracy and avoids the common phenomenon of uneven edges in the traditional cutting process.

[0041] Further, the auxiliary pressing device 6 further includes a guide seat 603 and a guide shaft 604. The guide seat 603 is provided on one side of the shearing machine bed 501, and the guide shaft 604 passes through the guide seat 603 and is connected to the second pressing plate 602. The guide shaft 604 in the auxiliary pressing device 6 is accurately positioned through the guide seat 603 to ensure that the up and down movement path of the second pressing plate 602 always remains vertical. The cooperation between the guide shaft 604 and the guide seat 603 not only provides the stability of the movement of the second pressing plate 602, but also avoids the deviation or inclination of the pressing plate 602 during the movement, thereby ensuring that the conveyor belt is subjected to a uniform pressing force during the cutting process and further improving the cutting accuracy. Through the accurate positioning of the guide seat 603 and the guide shaft 604, the auxiliary pressing device 6 can provide a more stable pressing effect during the cutting process, preventing the pressing plate 602 from tilting or deviating. In this way, the conveyor belt can maintain a more accurate position during cutting, avoiding uneven or skewed cut surfaces, and improving the cutting quality and the reliability of the equipment.

[0042] The working process of the above conveyor belt cutting machine is as follows:

[0043] Convey the conveyor belt along the idler 7 to the guiding beam 2, and place the conveyor belt between the two clamping devices 3 of the guiding beam 2. Adjust the sliding member 301 and the fixing member 303 in the clamping device 3 according to the width and thickness of the conveyor belt, so that the conveyor belt is positioned at an appropriate position. Then, by rotating the handwheel 3051, adjust the height between the first pressing plate 304 and the guiding beam 2 to ensure that the conveyor belt is firmly clamped. Start the moving device 4, so that the moving device 4 drives the cutting device 5 to move along with the vehicle body 401, and perform intermittent cutting in the width direction of the conveyor belt. At the same time, during the cutting process, synchronously start the auxiliary pressing device 6, and drive the second pressing plate 602 to move up and down by multiple second hydraulic cylinders 601 to perform secondary pressing on the conveyor belt to prevent the conveyor belt from drifting or displacing during the cutting process. The moving device 4 drives the cutting device 5 to continue cutting until the conveyor belt is completely cut off, and the cutting process is completed.
