Description

Technical Field

[0001] This utility model relates to the field of belt processing technology, specifically to a clamping device for belt processing. Background Technology

[0002] A belt, also known as a waist belt, is a strap-shaped accessory used to tighten clothing and secure garments, combining practicality and decoration. During belt manufacturing, the leather needs to be cut into sections. This cutting process requires clamping devices to hold the leather in place during movement, ensuring its stable feeding into the cutting machinery.

[0003] In the prior art, a Chinese patent document with publication number CN221501136U and publication date of August 9, 2024 was proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a clamping device for belt production and processing, including a frame; a fixed shell is fixedly installed on the top of the frame, a transmission mechanism is rotatably installed at both ends inside the frame, a connecting mechanism is fixedly installed at one end of the top of the fixed shell, a clamping mechanism is fixedly installed at the bottom of the connecting mechanism, and an auxiliary mechanism is fixedly installed at the center of the top of the frame.

[0004] To solve the problem of belt clamping during processing, the existing technology uses an electric push rod. The telescopic end of the electric push rod can drive the clamping mechanism at the bottom to move to the top of the belt, and then make the clamping roller abut against the top of the belt. The transmission mechanism then uses this method to transport the belt. However, this method cannot position the two sides of the belt, which makes the belt prone to tilting during transport and causes inaccurate cutting. Utility Model Content

[0005] The purpose of this invention is to provide a clamping device for belt processing to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A clamping device for belt processing includes a processing table, on both sides of the top of the processing table a supporting vertical plate is fixedly installed, and on all four sides of the bottom of the processing table a fixing leg is fixedly installed. A bracket is fixedly installed at the front right side of the supporting vertical plate.

[0008] The top of the processing table is provided with a clamping unit, and the front end of the top of the processing table is provided with a guide unit.

[0009] The clamping unit includes a limiting groove formed on the top of the processing table, and a limiting rod is fixedly installed on the inner wall of the limiting groove. The limiting rod can limit the adjustment of the spacing of the clamping plates.

[0010] A further improvement of this utility model is that: a fixing block is welded to both sides at the bottom center of the processing table, and a support frame is fixedly installed at the bottom center of the processing table.

[0011] A further improvement of this utility model is that a bidirectional motor is fixedly installed inside the support frame, and lead screws are fixedly installed on both output ends of the bidirectional motor. The other end of the lead screw is rotatably installed on the inner side of the fixed block. The model of the bidirectional motor is: MINASA6.

[0012] A further improvement of this utility model is that: a moving bracket is threaded onto the outer surface of the lead screw, a clamping plate is fixedly installed on the top of the moving bracket, and a roller is rotatably connected inside the clamping plate, which can reduce the friction on both sides when conveying by belt.

[0013] A further improvement of the present invention is that the guiding unit includes a guide wheel disposed at the front end of the top of the processing table, and a friction layer is fixedly sleeved on the outer surface of the guide wheel.

[0014] A further improvement of this utility model is that a servo motor is fixedly installed inside the bracket, and a drive rod is fixedly installed on the output end of the servo motor. The other end of the drive rod extends inside the guide wheel. The model of the servo motor is 1FT7087-7SF71-1CG1.

[0015] A further improvement of this utility model is that an electric telescopic rod is fixedly installed on both sides of the top rear end of the supporting vertical plate, and a cutting blade is fixedly installed on the top of the electric telescopic rod.

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0017] 1. This utility model provides a clamping device for belt processing. By setting a bidirectional motor to start running, the output ends on both sides drive the lead screw to rotate synchronously. The rotation of the lead screw causes the moving bracket to drive the clamping plate to follow the movement. Thus, the two sets of clamping plates can move relative to each other or in opposite directions at the same time, thereby achieving clamping and limiting of both sides of the belt and improving the accuracy of belt processing.

[0018] 2. This utility model provides a clamping device for belt processing. By setting a servo motor connected to the guide wheel through a drive rod, the guide wheel is driven to rotate. The friction layer on the outer surface of the guide wheel can increase the friction with the belt surface, ensuring that the belt is stably pulled during the conveying process.

[0019] 3. This utility model provides a clamping device for belt processing. By setting an electric telescopic rod, the bottom cutting blade is driven to descend vertically. When the cutting blade contacts the belt, it uses its sharp blade to complete the cutting action. After the cutting is completed, the electric telescopic rod retracts and the cutting blade returns to its original position, thereby achieving a rapid cutting effect. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0027] like Figure 1-5As shown, this utility model provides a clamping device for belt processing, including a processing table 1. Supporting vertical plates 2 are fixedly installed on both sides of the top of the processing table 1. Fixing legs 3 are fixedly installed around the bottom of the processing table 1. A bracket 4 is fixedly installed at the front right side of the supporting vertical plates 2. A clamping unit is provided on the top of the processing table 1, and a guiding unit is provided at the front top of the processing table 1. The clamping unit includes a limiting groove 11 formed on the top of the processing table 1, and a limiting rod 12 is fixedly installed on the inner wall of the limiting groove 11. Fixed blocks 13 are welded to both sides at the bottom center of the processing table 1. A bearing frame 14 is fixedly installed at the bottom center of the processing table 1. A bidirectional motor 15 is fixedly installed inside the bearing frame 14. A lead screw 16 is fixedly installed on both sides of the output end of the bidirectional motor 15. The other end of the lead screw 16 is rotatably installed on the inner side of the fixed block 13. A motion bracket 17 is threaded onto the outer surface of the lead screw 16. A clamping plate 18 is fixedly installed on the top of the motion bracket 17. A roller 19 is rotatably connected inside the clamping plate 18.

[0028] Furthermore, the bidirectional motor 15 starts to run, and its two output ends drive the lead screw 16 to rotate synchronously. The rotation of the lead screw 16 causes the motion bracket 17 to drive the clamping plate 18 to follow the movement. Thus, the two sets of clamping plates 18 can move relative to each other or in opposite directions at the same time, thereby achieving clamping and limiting of both sides of the belt. Example 2

[0029] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the guide unit includes a guide wheel 43 disposed at the front end of the top of the processing table 1, a friction layer 44 is fixedly sleeved on the outer surface of the guide wheel 43, a servo motor 41 is fixedly installed inside the bracket 4, a drive rod 42 is fixedly installed on the output end of the servo motor 41, and the other end of the drive rod 42 extends into the interior of the guide wheel 43.

[0030] Furthermore, the servo motor 41 is connected to the guide wheel 43 via the drive rod 42, thereby driving the guide wheel 43 to rotate. The friction layer 44 on the outer surface of the guide wheel 43 can increase the friction with the belt surface, ensuring that the belt is stably pulled during the conveying process. Example 3

[0031] like Figure 1-5 As shown, based on embodiments 1-2, this utility model provides a technical solution: preferably, an electric telescopic rod 21 is fixedly installed on both sides of the top rear end of the supporting vertical plate 2, and a cutting blade 22 is fixedly installed on the top of the electric telescopic rod 21.

[0032] Furthermore, the electric telescopic rod 21 drives the bottom cutting blade 22 to descend vertically. When the cutting blade 22 contacts the belt, it uses its sharp blade to complete the cutting action. After the cutting is completed, the electric telescopic rod 21 retracts and the cutting blade 22 returns to its original position.

[0033] The solution uses a PLC as the core control component. The PLC establishes a connection with the servo motor 41 and the bidirectional motor 15 through RS-485 communication. When it is necessary to start the servo motor 41 and the bidirectional motor 15, the PLC sends a start command to the servo motor 41 and the bidirectional motor 15 to start them.

[0034] The working principle of this clamping device used for belt processing will be explained in detail below.

[0035] like Figure 1-5 As shown, during use, the bidirectional motor 15 starts to run, and its output ends on both sides drive the lead screw 16 to rotate synchronously. The rotation of the lead screw 16 causes the motion bracket 17 to drive the clamping plate 18 to follow the movement. Thus, the two sets of clamping plates 18 can move relative to each other or in opposite directions at the same time, thereby achieving clamping and limiting of both sides of the belt. When the belt is placed on the processing table 1, the servo motor 41 is connected to the guide wheel 43 through the drive rod 42, thereby driving the guide wheel 43 to rotate. The friction layer 44 on the outer surface of the guide wheel 43 can increase the friction with the belt surface, ensuring that the belt is stably pulled during the conveying process. The electric telescopic rod 21 drives the bottom cutting blade 22 to descend vertically. When the cutting blade 22 contacts the belt, it uses its sharp blade to complete the cutting action. After the cutting is completed, the electric telescopic rod 21 retracts and the cutting blade 22 returns to its original position.

[0036] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
