Description

Technical Field

[0001] This utility model relates to the field of slitting machines, and in particular to a synchronous belt production slitting machine. Background Technology

[0002] Synchronous belt slitting machines are mechanical equipment used to cut and process synchronous belts. They mainly use rotary cutting to cut the whole synchronous belt into finished synchronous belts and are widely used in synchronous belt production.

[0003] The patent document with publication number "CN219669723U" discloses "a slitting machine with a wide range of applications and simple operation, including a machine base, an unwinding shaft rotatably mounted on the machine base, a guide roller group mounted above the unwinding shaft, a conveyor roller group, a cutter assembly mounted on the conveyor roller group, a take-up shaft mounted below the cutter assembly, and a take-up assembly." Although it has the effect of "the present invention cuts the edge strips of the roll material on the unwinding shaft through the cutter assembly and then takes the cut roll material back through the take-up shaft, and the cut edge strips enter the take-up hole and are blown out from the take-up tube by the blower," when using the slitting machine, the thickness of the synchronous belt produced is different, and the gap of the pressure rollers needs to be adjusted every time production is carried out. The repeated adjustment makes the production process cumbersome and cannot be used for synchronous belt slitting quickly and efficiently. Moreover, after the gap of the pressure rollers is adjusted, it is not possible to maintain constant pressure, which also makes it impossible to continuously and stably use synchronous belt slitting processing. Utility Model Content

[0004] The main objective of this invention is to provide a synchronous belt production slitting machine that can effectively solve the technical problems raised in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A synchronous belt slitting machine includes a mounting frame, a slitting mounting rod, slitting blades, a take-up roller, and a guide roller. The slitting mounting rod and the take-up roller are rotatably mounted above the front end of the mounting frame, with the slitting mounting rod located to one side of the take-up roller. Multiple slitting blades are fixedly sleeved on the outer side of the slitting mounting rod. The guide roller is movably mounted at the front end of the mounting frame and below the take-up roller. Two drive motors are fixedly mounted on the lower inner side of the mounting frame. Two drive rods are movably mounted on the upper inner side of the mounting frame. A drive pulley is fixedly mounted at the rear end of each drive rod. A drive belt is movably mounted on one end of the shaft of each drive motor and the outer side of the drive pulley. A transmission structure is provided at the bottom inner side of the mounting frame. A linkage rod is movably mounted at the front upper end of the mounting frame. A pressure roller structure is provided at the front end of the mounting frame below the slitting mounting rod.

[0007] As a further embodiment of this utility model, the drive motor drives the drive pulley and drive rod to rotate via a drive belt, and the front ends of the two drive rods are fixedly connected to the slitting mounting rod and the take-up roller.

[0008] As a further embodiment of this utility model, the transmission structure includes a transmission rod, transmission bevel teeth, a transmission pulley, a linkage pulley, and a transmission belt. The linkage pulley is movably installed on the inner bottom of the mounting frame, the transmission rod is movably installed on the inner side of the mounting frame and located on one side of the drive motor, the two transmission bevel teeth are respectively fixedly installed on the upper end of the transmission rod and the outer side of the drive rod, the transmission pulley is fixedly installed on the lower end of the transmission bevel teeth, and the transmission belt is movably installed on the outer side of the transmission pulley and the linkage pulley.

[0009] As a further embodiment of this utility model, the upper end of the transmission rod is located on one side of the drive rod, the two transmission bevel teeth are meshed and connected, and the lower end of the linkage rod is fixedly connected to the linkage pulley.

[0010] As a further embodiment of this utility model, the pressure roller structure includes a pressure roller support plate, a threaded ring, a lifting mounting groove, a pressure roller mounting seat, a slitting pressure roller, a guide mounting block, and a buffer spring. The pressure roller support plate is movably installed at the front end of the mounting frame, the threaded ring is fixedly installed in the middle of the pressure roller support plate, the lifting mounting groove is opened at the rear end of the pressure roller support plate, the pressure roller mounting seat is movably installed in the lifting mounting groove at the rear end of the pressure roller support plate, the slitting pressure roller is movably installed at the front end of the pressure roller mounting seat, the guide mounting block is fixedly installed at the rear end of the pressure roller support plate, and the buffer spring is fixedly installed between the guide mounting block and the pressure roller mounting seat.

[0011] As a further embodiment of this utility model, the slitting pressure roller is located below the slitting mounting rod, the upper end of the linkage rod passes through the pressure roller bracket plate and is threadedly connected to the threaded ring, and the pressure roller mounting seat moves up and down around the lifting mounting groove.

[0012] Compared with the prior art, the present invention has the following advantages: by the synchronous rise of the slitting pressure roller, when the slitting mounting rod and the slitting blade slit the synchronous belt, the slitting pressure roller is simultaneously driven to move upward to press the synchronous belt, which eliminates the trouble of adjusting the gap when slitting the synchronous belt, and allows for faster and more efficient slitting of the synchronous belt.

[0013] The elastic buffer of the slitting pressure roller causes the buffer spring to contract when the upward pressure of the slitting pressure roller is too great. Finally, after the linkage rod moves to the upper limit of the threaded ring, the rebound of the buffer spring ensures that the slitting pressure roller always moves upward, maintaining the pressure on the synchronous belt and enabling more continuous and stable synchronous belt slitting.

[0020] like Figures 1-4 As shown, a synchronous belt slitting machine is provided. Please refer to it carefully. Figures 1-4 The system includes a mounting frame 1, a slitting mounting rod 2, slitting blades 3, a take-up roller 4, and a guide roller 5. The slitting mounting rod 2 and the take-up roller 4 are rotatably mounted above the front end of the mounting frame 1, with the slitting mounting rod 2 located on one side of the take-up roller 4. Multiple slitting blades 3 are fixedly sleeved on the outside of the slitting mounting rod 2. The guide roller 5 is movably mounted at the front end of the mounting frame 1 and located below the take-up roller 4. Two drive motors 6 are fixedly mounted on the lower inner side of the mounting frame 1, and two drive rods 9 are movably mounted on the upper inner side of the mounting frame 1. A drive pulley 8 is fixedly mounted at the rear end of the drive rods 9. A drive belt 7 is movably mounted on one end of the shaft of the drive motor 6 and the outside of the drive pulley 8. A transmission structure 10 is provided at the bottom inner side of the mounting frame 1. A linkage rod 16 is movably mounted at the front upper end of the mounting frame 1. A pressure roller structure 17 is provided at the front end of the mounting frame 1 below the slitting mounting rod 2.

[0021] Please refer to this carefully. Figures 1-3 The drive motor 6 drives the drive pulley 8 and drive rod 9 to rotate via the drive belt 7. The front ends of the two drive rods 9 are fixedly connected to the slitting mounting rod 2 and the take-up roller 4.

[0022] Specifically, the operation of the drive motor 6 drives the drive rod 9 to rotate, and the drive rod 9 in turn drives the slitting mounting rod 2 and the take-up roller 4 to rotate.

[0023] Please refer to this carefully. Figures 1-3 The transmission structure 10 includes a transmission rod 11, a transmission bevel gear 12, a transmission pulley 13, a linkage pulley 14, and a transmission belt 15. The linkage pulley 14 is movably mounted on the inner bottom of the mounting frame 1. The transmission rod 11 is movably mounted on the inner side of the mounting frame 1 and located on one side of the drive motor 6. The two transmission bevel gears 12 are respectively fixedly mounted on the upper end of the transmission rod 11 and the outer side of the drive rod 9. The transmission pulley 13 is fixedly mounted on the lower end of the transmission bevel gear 12. The transmission belt 15 is movably mounted on the outer side of the transmission pulley 13 and the linkage pulley 14.

[0024] Please refer to this carefully. Figures 1-3 The upper end of the transmission rod 11 is located on one side of the drive rod 9, and the two transmission bevel teeth 12 are meshed together. The lower end of the linkage rod 16 is fixedly connected to the linkage pulley 14.

[0025] Specifically, when the drive rod 9 rotates, it drives the transmission rod 11 to rotate through the transmission bevel gear 12. The transmission rod 11 then drives the linkage pulley 14 to rotate through the transmission pulley 13 and the transmission belt 15. Finally, the linkage pulley 14 drives the linkage rod 16 to rotate.

[0026] Please refer to this carefully. Figure 4 The pressure roller structure 17 includes a pressure roller support plate 18, a threaded ring 19, a lifting mounting groove 20, a pressure roller mounting seat 21, a slitting pressure roller 22, a guide mounting block 23, and a buffer spring 24. The pressure roller support plate 18 is movably installed at the front end of the mounting frame 1. The threaded ring 19 is fixedly installed in the middle of the pressure roller support plate 18. The lifting mounting groove 20 is opened at the rear end of the pressure roller support plate 18. The pressure roller mounting seat 21 is movably installed in the lifting mounting groove 20 at the rear end of the pressure roller support plate 18. The slitting pressure roller 22 is movably installed at the front end of the pressure roller mounting seat 21. The guide mounting block 23 is fixedly installed at the rear end of the pressure roller support plate 18. The buffer spring 24 is fixedly installed between the guide mounting block 23 and the pressure roller mounting seat 21.

[0027] Please refer to this carefully. Figure 4 The slitting pressure roller 22 is located below the slitting mounting rod 2. The upper end of the linkage rod 16 passes through the pressure roller bracket plate 18 and is threadedly connected to the threaded ring 19. The pressure roller mounting seat 21 moves up and down around the lifting mounting groove 20.

[0028] Specifically, when the synchronous belt is slitting, it is inserted between the slitting mounting rod 2 and the slitting pressure roller 22. The rotation of the slitting mounting rod 2 causes the slitting blade 3 to slit the synchronous belt and convey the synchronous belt to one side. The slitting synchronous belt passes around the guide roller 5 and wraps around the outside of the take-up roller 4. The take-up roller 4 then takes up the synchronous belt to complete the slitting of the synchronous belt.

[0029] The synchronous rotation of the linkage rod 16 via the transmission structure 10 causes the pressure roller support plate 18 to move upward through the threaded connection with the threaded ring 19, thereby causing the slitting pressure roller 22 to move upward. This allows the slitting mounting rod 2 and the slitting blade 3 to slit the synchronous belt while simultaneously causing the slitting pressure roller 22 to move upward and press the synchronous belt.

[0030] When the upward pressure of the slitting roller 22 is too great due to the elastic buffer of the slitting roller 22, the roller mounting seat 21 moves downward around the lifting mounting groove 20, which in turn presses the buffer spring 24 to retract. Finally, after the linkage rod 16 moves the threaded ring 19 to the upper limit, the rebound of the buffer spring 24 makes the slitting roller 22 always move upward, maintaining the pressure on the synchronous belt.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
