Description

Technical Field

[0001] This utility model relates to the field of synchronous belt production equipment technology, and more specifically, to an automatic tooth-counting cutting system for synchronous belts. Background Technology

[0002] Synchronous belts, also known as toothed synchronous belts or timing belts, are similar to common belt drives such as V-belts and flat belts, and are a type of flexible transmission. Synchronous toothed belts use steel wire rope or fiberglass rope as the reinforcing layer, covered with polyurethane or neoprene rubber. The inner circumference of the belt is toothed to mesh with toothed pulleys. Because the reinforcing layer deforms little under load, it maintains a constant circumferential pitch, thus preventing relative slippage between the belt and pulleys and ensuring synchronous transmission with a constant transmission ratio. They can also be used for low-speed transmissions requiring synchronization.

[0003] To adapt to the transmission needs of different equipment, the size and number of teeth of the timing belt vary at different locations. When manufacturing timing belts, it is necessary to first cut a section with the corresponding number of teeth from the raw material belt, and then join the two ends together. Currently, in the workshop production process, only manual tooth counting and manual cutting can be used, which results in low processing efficiency and unreliable production quality.

[0004] Currently, there are synchronous belt automatic tooth counting devices on the market, such as the patent document with patent number CN202110887965.7 entitled "A Tooth Counting Machine". The device specifically includes: a base, a tooth counting platform, a lifting device, and a protective cover. The tooth counting platform is installed on the top of the base, and a handle is installed on the tooth counting platform. The protective cover is installed on the top of the base above the tooth counting platform, and an insert plate is inserted into the protective cover. The lifting device is connected to the side of the base away from the tooth counting platform. The upper surface of the base is provided with a coding machine component and a side pressure roller on both sides of the protective cover. An operation box is installed on the base on one side of the coding machine component.

[0005] However, the aforementioned equipment can only mark the number of teeth after counting them; the timing belt must then be removed and cut separately, which is cumbersome and requires significant automation. Therefore, it is necessary to develop equipment that can automatically complete both the tooth counting and cutting processes. Utility Model Content

[0006] To address the lack of automated custom production equipment for synchronous belts capable of automatically completing tooth counting and cutting processes, and the low efficiency of custom tooth cutting for synchronous belts, we provide an automated tooth counting and cutting system for synchronous belts.

[0007] The automatic tooth-counting cutting system with synchronous belts includes a tooth-counting assembly, a cutting platform, and an industrial control module. The tooth-counting assembly includes a synchronous pulley horizontally arranged on the central shaft. The synchronous pulley is detachably sleeved on the output shaft of a servo motor. A lifting driver is connected to the servo motor. A support roller is provided below the synchronous pulley. The cutting platform is located behind the synchronous pulley in the pushing direction. The cutting platform includes a flat pad, a cutting pressure plate is provided above the flat pad, and a lifting push rod is connected to the top of the cutting pressure plate. A cutting channel is provided between the flat pad and the cutting pressure plate. The servo motor, the lifting driver, and the lifting push rod are all electrically connected to the industrial control module.

[0008] Furthermore, the servo motor is slidably sleeved on the lifting guide rail, and the output shaft of the servo motor is connected in series with a horizontal rotating shaft through a coupling. A rotary bearing is sleeved on the horizontal rotating shaft, and a synchronous pulley is connected in series to the front end of the horizontal rotating shaft.

[0009] Furthermore, the surface of the support roller is covered with a soft padding layer, and both ends of the support roller are rotatably connected with seated bearings.

[0010] Furthermore, a guide groove is provided between the tooth counting assembly and the cutting platform, and a width adjustment side plate is provided on the side of the guide groove. The bottom of the width adjustment side plate is connected to the width adjustment screw by a nut.

[0011] Furthermore, the bottom of the width-adjusting side plate is slidably fitted with an adjusting guide rail.

[0012] Furthermore, a drive component is connected in series on the width-adjusting lead screw. The drive component includes an adjustment handle and a lead screw motor. The adjustment handle is oriented in the same direction as the industrial control module.

[0013] Furthermore, a lower cutting die is detachably mounted on the flat pad, and an upper cutting die is detachably mounted on the bottom of the cutting pressure plate, with the lower cutting die and the upper cutting die engaging with each other.

[0014] Furthermore, positioning guide posts are provided at the four corners of the lower cutting die, and positioning sleeves are provided at the bottom of the upper cutting die corresponding to the positioning guide posts. The top of the positioning guide posts is spherical.

[0015] Furthermore, a guide column is installed on the flat pad, and a linear bearing is installed on the cutting plate corresponding to the guide column, with the linear bearing slidably sleeved on the guide column.

[0016] Furthermore, the industrial control module has a display screen and operation buttons on its front side.

[0033] like Figures 1 to 5As shown, this embodiment provides a synchronous belt automatic tooth counting cutting system, including a tooth counting assembly, a cutting platform 2, and an industrial control module 3. The tooth counting assembly includes a synchronous belt pulley 1 horizontally arranged on the central shaft. The synchronous belt pulley 1 is detachably sleeved on the output shaft of a servo motor 101. A lifting driver 102 is connected to the servo motor 101. A support roller 4 is arranged below the synchronous belt pulley 1. The cutting platform 2 is arranged on the rear side of the synchronous belt pulley 1 in the pushing direction. The cutting platform 2 includes a flat pad 201. A cutting pressure plate 202 is arranged above the flat pad 201. A lifting push rod 203 is connected to the top of the cutting pressure plate 202. A cutting channel 204 is arranged between the flat pad 201 and the cutting pressure plate 202. The servo motor 101, the lifting driver 102, and the lifting push rod 203 are all electrically connected to the industrial control module 3.

[0034] The industrial control module 3 can be a commercially available PLC or industrial control all-in-one machine, which will not be elaborated here. During equipment operation, the synchronous belt material is first placed on the support roller 4. Then, based on the thickness of the synchronous belt material, the lifting driver 102 is activated to press the synchronous belt pulley 1 onto the material, clamping the synchronous belt between the support roller 4 and the synchronous belt pulley 1. The synchronous belt pulley 1 is then rotated a certain number of teeth, outputting the required number of teeth of the synchronous belt material into the cutting channel 204. Subsequently, the cutting plate 202 presses down to cut the synchronous belt material into corresponding synchronous belt segments, which are then removed for further synchronous belt processing to obtain a synchronous belt with the customized number of teeth. It should be noted that since there is a gap when the synchronous belt material is output from the synchronous belt pulley 1 into the cutting channel 204, when setting the number of teeth, it is essential to ensure that the rotation stroke of the synchronous belt pulley 1 is the sum of the synchronous belt length and the gap.

[0035] The servo motor 101 is slidably sleeved on the lifting guide rail 103. The output shaft of the servo motor 101 is connected in series with a horizontal rotating shaft 105 via a coupling 104. A rotary bearing 106 is sleeved on the horizontal rotating shaft 105, and a synchronous pulley 1 is connected in series to the front end of the horizontal rotating shaft 105. The lifting guide rail 103 can improve the lifting stability of the servo motor 101; while the structure of the coupling 104, the horizontal rotating shaft 105, and the rotary bearing 106 can improve the running stability of the synchronous pulley 1.

[0036] The surface of the support roller 4 is covered with a soft padding layer, and both ends of the support roller 4 are rotatably connected to a seated bearing 401. The soft padding layer can be made of commercially available PU material, which has properties such as high elasticity, wear resistance, tear resistance, and impact resistance. In this embodiment, the support roller 4 directly uses a commercially available PU wheel, resulting in low component costs. The seated bearing 401 provides stable support for the support roller 4.

[0037] A guide groove 5 is provided between the tooth counting assembly and the cutting platform 2. An adjustable width side plate 501 is provided on the side of the guide groove 5, and the bottom of the adjustable width side plate 501 is connected to the adjustable width screw 503 via a nut 502. Since there is a certain distance between the tooth counting assembly and the cutting platform 2, the guide groove 5 is provided to ensure that the synchronous belt material pushed by the synchronous pulley 1 can accurately enter the cutting channel 204. Because the width of the synchronous belt material varies, the adjustable width side plate 501 with adjustable spacing is provided to accommodate synchronous belts of various widths.

[0038] The bottom of the adjustable side plate 501 is slidably fitted with an adjusting guide rail 504. The adjusting guide rail 504 ensures the smooth movement of the adjustable side plate 501 and provides support for the adjustable side plate 501.

[0039] A drive component is connected in series on the width-adjusting lead screw 503. The drive component includes an adjustment handle 6 and a lead screw motor. The adjustment handle 6 faces the same direction as the industrial control module 3 for easy manual operation. The lead screw motor can be connected to the industrial control module 3 to achieve automatic width adjustment.

[0040] A lower cutting die 701 is detachably mounted on the flat pad 201, and an upper cutting die 702 is detachably mounted on the bottom of the cutting pressure plate 202. The lower cutting die 701 and the upper cutting die 702 are interlocked. Since the width specifications of synchronous belts vary and the butt joint process includes different types such as hot vulcanization joints, detachable cutting dies are provided to adapt to different cutting needs.

[0041] The lower cutting die 701 has positioning guide pillars 703 at each of its four corners, and the lower cutting die 702 has a positioning sleeve 704 at its bottom corresponding to the positioning guide pillars 703. The top of the positioning guide pillars 703 is spherical. The positioning guide pillars 703 and the positioning sleeves 704 can ensure the alignment accuracy of the cutting die and avoid the deviation of the cut position.

[0042] A guide column 8 is installed on the flat pad 201, and a linear bearing 801 is installed on the cutting plate 202 corresponding to the guide column 8. The linear bearing 801 is slidably sleeved on the guide column 8. The guide column 8 can improve the running stability of the cutting plate 202.

[0043] The industrial control module 3 has a display screen 301 and operation buttons 302 on its front. Since the size and number of teeth of the timing belt need to be changed frequently, especially when the timing belt is used to replace equipment during production and maintenance, the size and number of teeth of the timing belt to be produced are determined according to the damage situation of the required equipment, which is highly random. Therefore, the display screen 301 and operation buttons 302 enable the staff to quickly set the required parameters.

[0044] The above description is a further detailed explanation of the present utility model in conjunction with specific preferred embodiments. It should not be assumed that the specific implementation of the present utility model is limited to these descriptions. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present utility model.
