Description

Technical Field

[0001] This utility model relates to the field of belt processing technology, and in particular to a buckle sewing device for belt processing. Background Technology

[0002] As a common everyday accessory, belts are usually made of leather, fabric or synthetic materials and are equipped with buckles for adjusting length and securing. When sewing belts, sewing equipment is needed to sew the buckles. As one of the key components of a belt, the sewing process of the buckles directly affects the belt's lifespan, appearance and comfort.

[0003] However, existing buckle sewing devices for belt processing usually require manual intervention from workers to ensure the stability of the sewing process. Specifically, during the sewing process, due to the elasticity or softness of the belt material, the belt may shake or slide on the sewing machine's worktable. Such shaking can easily cause the buckle and belt to shift in position, thus affecting the sewing accuracy. To avoid this, workers usually need to operate the sewing equipment while manually pressing and fixing the belt to ensure that it does not become misaligned during sewing. However, this manual pressing method not only increases the complexity of the operation but also greatly increases the labor intensity of production, consuming a lot of time and energy. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Example 1, please refer to Figures 1 to 4This utility model provides a technical solution: a buckle sewing device for belt processing, including a processing table 1. A sewing machine 101 is arranged on the top left side of the processing table 1, and a positioning plate 102 is arranged on the top right side of the processing table 1. Two first sliding rods 103 are fixedly installed on both sides of the top of the positioning plate 102. Two movable parts 104 are slidably connected to the outer surfaces of the two first sliding rods 103. Bolts 105 are threadedly connected to the interior of the four movable parts 104. The four movable parts 104 are divided into two groups of two. Both gantry frames 106 are fixedly installed on top of each gantry frame 106. Lifting assemblies are installed inside each gantry frame 106. Each lifting assembly includes a forward rotating lead screw 107 and a slide groove 111. The rear outer surface of the forward rotating lead screw 107 is movably embedded in the rear inner wall of the gantry frame 106. A reverse rotating lead screw 108 is fixedly installed on the front side of the forward rotating lead screw 107. The front outer surface of the reverse rotating lead screw 108 is movably embedded in the front inner side of the gantry frame 106. A motor 109 is fixedly installed on the front side of the reverse rotating lead screw 108. The bottom of the motor 109 is fixedly installed on the gantry frame. At the top front side of 106, the outer surfaces of the forward-rotating lead screw 107 and the reverse-rotating lead screw 108 are threadedly connected to first sliders 110. A slide groove 111 is formed on the top side of the inner wall of the gantry frame 106. First hinges 112 are fixedly installed at the bottom of each of the two first sliders 110. The top outer surfaces of the two first sliders 110 are slidably connected to the inner surface of the slide groove 111. Support rods 113 are movably connected inside each of the two first hinges 112. Second hinges 114 are movably connected to the other ends of each of the two second hinges 114. A first clamping plate 115 is fixedly installed at the bottom of 14. The first clamping plate 115 is slidably connected to the inside of the gantry frame 106. A second slider 3 is fixedly installed at the bottom of the positioning plate 102. The second slider 3 is slidably connected to the inside of the processing table 1. An electric telescopic rod 301 is fixedly installed on the left side of the second slider 3. The other end of the electric telescopic rod 301 is fixedly installed on the bottom left side of the processing table 1. Two second sliding rods 302 are fixedly installed at the bottom of the processing table 1. The outer surface of the second slider 3 is slidably connected to the outer surface of the two second sliding rods 302.

[0032] In this embodiment, the operator can first assemble the buckle onto the belt and place it on top of the positioning plate 102. Then, using the reversing bolt 105, one end of the buckle is disengaged from the first slide rod 103. Next, the operator pushes the gantry frame 106, causing the movable part 104 to slide on the outer surface of the first slide rod 103 to adjust the position of the gantry frame 106. Once the position is adjusted, the operator can start the motor 109 via its power supply system. During operation, the motor 109 will drive the output shaft to the reversing lead screw 108, which in turn drives the forward lead screw 107. As the forward and reversing lead screws 107 and 108 rotate, they will cause the first slider 110 to slide relative to each other through the slide groove 111. When the slider 110 moves, it pulls the support rod 113 through the first hinge 112, causing it to flip through the second hinge 114. At the same time, the second hinge 114 presses down the first clamping plate 115, allowing it to fit against the top of the belt and buckle and fix them in place. Then, the operator can start the sewing machine 101 through the drive system of the sewing machine 101 on the processing table 1 to sew the belt and buckle. While the belt and buckle are being sewn, the operator can start the electric telescopic rod 301 through the power supply system of the electric telescopic rod 301. When it retracts, it pulls the second slider 3 to slide to the left on the outer surface of the second slide rod 302. Then, the second slider 3 pulls the belt and buckle to move to the left synchronously through the positioning plate 102.

[0033] Example 2, as Figures 5 to 6 As shown, the lifting assembly also includes a screw 2, which is threadedly connected to the top side of the inside of the gantry frame 106. The bottom of the screw 2 is movably connected to a second clamping plate 201, which is slidably connected to the inside of the gantry frame 106. Positioning posts 202 are fixedly installed on both sides of the top of the second clamping plate 201, and both positioning posts 202 are movably embedded in the inside of the gantry frame 106. A crank handle 203 is fixedly installed on the top of the screw 2.

[0034] In this embodiment, after the position of the gantry frame 106 is adjusted, the operator can turn the crank handle 203 to drive the screw 2 to rotate. When the screw 2 rotates, it can push the second clamping plate 201 downward, and at the same time, the second clamping plate 201 pulls the positioning column 202 to slide inside the gantry frame 106, so that the second clamping plate 201 can fit against the top of the belt and buckle and fix them.

[0035] Working principle: In use, the operator first assembles the buckle onto the belt and places it on top of the positioning plate 102. Then, using the reversing bolt 105, one end of the buckle disengages from the first slide rod 103. Next, the operator pushes the gantry frame 106, causing the movable part 104 to slide on the outer surface of the first slide rod 103 to adjust the position of the gantry frame 106. Once the position is adjusted, the operator can start the motor 109 via its power supply system. During operation, the motor 109 transmits power through its output shaft to the reversing screw 108, which in turn transmits power to the forward screw. 107. When the forward lead screw 107 and the reverse lead screw 108 rotate, they will drive the first slider 110 to slide in opposite directions through the slide groove 111. When the first slider 110 is moving, it will pull the support rod 113 through the first hinge 112, causing it to flip through the second hinge 114. At the same time, the first clamping plate 115 will be pressed down through the second hinge 114, so that it can fit against the top of the belt and buckle and fix them. Then, the operator can start the sewing machine 101 through the drive system of the sewing machine 101 on the processing table 1 to sew the belt and buckle. After the position of the gantry frame 106 is adjusted, the operator can turn the crank handle 203 to rotate the screw 2. When the screw 2 rotates, it pushes the second clamping plate 201 downwards. At the same time, the second clamping plate 201 pulls the positioning column 202 to slide inside the gantry frame 106, so that the second clamping plate 201 can fit against the top of the belt and buckle and fix them. Through the structure of the forward rotating screw 107 and the screw 2, the belt and buckle can be accurately fixed on the processing table 1, ensuring the precise alignment of the buckle and belt. This not only avoids the misalignment or asymmetry that may occur during manual operation, thus ensuring the accuracy of sewing, but also reduces the labor intensity of the workers and reduces human error. In use, when the belt and buckle are being sewn, the operator can activate the electric telescopic rod 301 through its power supply system. When the rod retracts, it pulls the second slider 3 to slide to the left on the outer surface of the second slider 302. The second slider 3 then pulls the belt and buckle to move to the left synchronously through the positioning plate 102. The structure of the electric telescopic rod 301 and the second slider 3 eliminates the need for the operator to manually move the belt and buckle, further reducing errors and instability caused by manual operation, improving production efficiency, and reducing the labor intensity of workers.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
