Description

Technical Field

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

[0002] Synchronous belts are transmission components that combine the advantages of chain, gear, and belt drives. They consist of a reinforcing layer, a toothed layer, and a fabric covering. The reinforcing layer is typically made of materials such as fiberglass or steel wire, providing high strength and low elongation. The toothed layer is made of polyurethane or rubber, with equidistant teeth on the inner side, allowing for precise meshing with the grooves on the pulleys to achieve slip-free synchronous transmission. They are widely used in CNC machine tools, textile machinery, printers, and other equipment. During the manufacturing process, a slitting device is used to cut the synchronous belt into equal-sized pieces.

[0003] In daily work, we have found that adjusting the position of the cutting blades in the actual operation of the synchronous belt slitting machine is a significant problem due to its cumbersome nature. In the existing equipment, each cutting blade is independently equipped with a binding and fixing structure. During adjustment, each cutting blade must be loosened one by one. The binding device of a single cutting blade must be released before it can be moved to the target position. After the position is determined, the binding structure of each cutting blade must be tightened again to ensure that it is firmly fixed. The entire process requires operation on all cutting blades one by one, which is repetitive and time-consuming. Especially when multiple cutting blades need to be adjusted at the same time, the operation efficiency is extremely low. Utility Model Content

The steps are repetitive and time-consuming, especially when the positions of multiple cutting blades need to be adjusted at the same time, resulting in extremely low operating efficiency. Therefore, a synchronous belt slitting machine is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a synchronous belt slitting machine, comprising a machine body, a synchronous pulley, a limiting pulley, a limiting sleeve, and a cutting device. The synchronous pulley is disposed in the machine body and driven by a motor. The limiting pulley is disposed in the machine body. The limiting sleeve is mounted on the surface of the machine body.

Through the above-mentioned components, the pad and the protrusions fit together to adhere to the protrusion, which can improve the overall stability.

[0010] Preferably, a handle is fixedly connected to the surface of the protrusion. Through the above-mentioned components, the protrusion and the cutting part can be moved by the handle, thereby improving the overall ease of use.

[0011] Preferably, the surface of the mounting bracket is provided with graduations to improve the accuracy of adjustment.

[0012] Preferably, the connecting assembly includes protruding plates fixed on both sides of the mounting bracket, a plurality of positioning rods are fixedly connected to the surface of the limiting sleeve, the positioning rods are inserted into the inner wall of the protruding plates, two clamping plates are slidably connected to the inner wall of the limiting sleeve, the clamping plates are inserted into the inner wall of the protruding plates, a second screw is rotatably connected to the inner wall of the limiting sleeve, the second screw is threadedly connected to the inner wall of the two clamping plates, and a second knob is fixedly connected to one end of the second screw.

[0013] Preferably, both screw one and screw two are bidirectional screws.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, by setting up a cutting device, multiple sets of cutting parts can be synchronously fixed through the cooperation of screw one and two extrusion plates. During adjustment, simply slide the cutting part to the target position, rotate knob one and screw one to drive the two extrusion plates to move along the guide rod, clamp the protrusions of all cutting parts, and complete the positioning of all cutting blades at one time. There is no need to operate one by one, which greatly reduces the adjustment steps, reduces the operation intensity, and significantly improves the adjustment efficiency.

[0016] 2. In this utility model, by setting an anti-slip part, which is composed of a pad and multiple protrusions, the friction between the extrusion plate and the protrusion can be improved, thus ensuring the overall stability.

[0017] 3. By setting up connecting components, the interaction between knob two, screw two, clamping plate, protruding plate and positioning rod facilitates quick assembly and disassembly of the mounting bracket, improving overall usability. Attached Figure Description

[0025] Please see Figure 1 - Figure 5This utility model provides a technical solution: a synchronous belt slitting machine, including a machine body 1, a synchronous wheel 2, a limiting wheel 3, a limiting sleeve 4 and a cutting device 5. The synchronous wheel 2 is disposed in the machine body 1 and driven by a motor. The limiting wheel 3 is disposed in the machine body 1. The limiting sleeve 4 is mounted on the surface of the machine body 1 and the cutting device 5 is disposed on the surface of the limiting sleeve 4.

[0026] Specifically, the cutting device 5 includes a mounting bracket 51 located on one side of the limiting sleeve 4. The mounting bracket 51 and the cutting device 5 are connected by a connecting component 6. Multiple sets of cutting parts 52 for slid cutting are slidably connected to the inner wall of the mounting bracket 51. Protrusions 53 are fixedly connected to the surface of the cutting parts 52. A guide rod 510 is fixedly connected to the surface of the mounting bracket 51. Two extrusion plates 59 are slidably connected to the surface of the guide rod 510. A screw 56 is rotatably connected to the inner wall of the mounting bracket 51. The screw 56 is threadedly connected to the inner wall of the two extrusion plates 59. A knob 55 is fixedly connected to one end of the screw 56. A scale 511 is opened on the surface of the mounting bracket 51 to facilitate the improvement of adjustment accuracy.

[0027] In this embodiment: multiple cutting pieces 52 can be slid in the mounting bracket 51 to adjust their positions. After adjustment, screw 56 can be rotated to control the movement of two extrusion plates 59 and clamp them on the protrusion 53, thereby positioning the cutting blade and facilitating quick adjustment of the cutting size.

[0028] Specifically, the cutting component 52 includes an upper slider 521 and a lower slider 523 that are slidably connected to the inner wall of the mounting bracket 51, and a blade body 522 is fixedly connected between the upper slider 521 and the lower slider 523.

[0029] Specifically, the surface of the extrusion plate 59 is fixedly connected with multiple anti-slip parts, which are arranged at equal intervals. Each anti-slip part includes a pad 57 fixed to the surface of the extrusion plate 59, and the surface of the pad 57 is fixedly connected with multiple protrusions 58.

[0030] In this embodiment: when the extrusion plate 59 is used in conjunction with the anti-slip part for extrusion clamping, the pad 57 and the protrusion 58 are attached to the protrusion 53, which can improve the overall stability.

[0031] Specifically, a handle 54 is fixedly connected to the surface of the protrusion 53, which can be used to move the protrusion 53 and the cutting part 52, thereby improving the overall ease of use.

[0032] Specifically, the connecting component 6 includes protruding plates 61 fixed on both sides of the mounting bracket 51, multiple positioning rods 65 fixedly connected to the surface of the limiting sleeve 4, the positioning rods 65 being inserted into the inner wall of the protruding plate 61, two clamping plates 62 being slidably connected to the inner wall of the limiting sleeve 4, the clamping plates 62 being inserted into the inner wall of the protruding plate 61, a screw 63 being rotatably connected to the inner wall of the limiting sleeve 4, the screw 63 being threadedly connected to the inner wall of the two clamping plates 62, and a knob 64 being fixedly connected to one end of the screw 63.

[0033] In this embodiment: by inserting the positioning rod 65 into the inner wall of the protruding plate 61, and then rotating the second knob 64 and the second screw 63, the locking plate 62 is controlled to be locked into the inner wall of the protruding plate 61, thus completing the installation of the mounting bracket 51 and facilitating subsequent replacement operations.

[0034] Specifically, both screw 1 (56) and screw 2 (63) are bidirectional screws.

[0035] Working principle: In use, firstly, multiple cutting pieces 52 are slid in the mounting bracket 51 according to the requirements, and precise adjustment is achieved according to the scale 511. After adjustment, the knob 55 and screw 56 are rotated. Screw 56 controls the movement of two extrusion plates 59. The extrusion plates 59, together with the shims 57 and protrusions 58, press against the protrusions 53 to position the multiple adjusted cutting pieces 52. Then, the timing belt to be cut is inserted into the limiting sleeve 4. The blades 522 in the cutting pieces 52 pre-cut the timing belt. After cutting, the timing belt is placed on the timing wheel 2, and the limiting wheel 3 restricts it. The motor drives the timing wheel 2 to rotate, thereby driving the timing belt to move and realize the cutting operation. When it is necessary to remove the mounting bracket 51, simply rotate the knob 64 and screw 63. Screw 63 can drive the clamping plate 62 to move out of the inner wall of the protrusion plate 61 one by one. Then, the protrusion plate 61 is pulled out from the positioning rod 65 to complete the removal operation.
