Description

Technical Field

[0001] The present invention relates to the technical field of button sewing machines, in particular to a full-automatic pneumatic button sewing machine. Background Art

[0002] In coal mining and transportation operations, conveyor belts, as core material transport equipment, are responsible for the continuous transportation of bulk cargo such as coal and ore. The reliability and efficiency of their joint connections are directly related to the safe and stable operation of coal mine production lines and overall operational efficiency. Broken or loose conveyor belt joints can not only disrupt material transportation but also cause serious accidents such as belt deviation, tearing, and even equipment damage, resulting in significant losses to coal mine production. Therefore, improving the quality and speed of conveyor belt joint bonding has become a key requirement for technological upgrades in the coal mining industry.

[0003] Currently, the binding of metal U-joints (belt buckles) for coal mine conveyor belts relies primarily on traditional manual pneumatic buckle machines. This equipment uses a human lever principle, with the operator repeatedly applying pressure to secure the buckle. However, this traditional method has the following significant drawbacks:

[0004] Traditional manual buckle-stitching machines require operators to continuously apply force and repeatedly adjust the lever position to gradually tighten the buckle. For example, a single buckle-stitching cycle for a one-meter-wide conveyor belt joint takes an average of approximately 15 minutes, requiring multiple people to coordinate and control the conveyor belt position and buckle-stitching rhythm. Given the high-yield and high-efficiency production model of coal mines, this inefficient buckle-stitching method has become a bottleneck restricting capacity expansion.

[0005] Repeated manual pressure exerts significant physical strain on operators, especially during long periods of continuous work. This can easily lead to occupational hazards such as muscle fatigue, joint strain, and even lumbar spine injuries. Furthermore, high-intensity labor reduces operators' attention span and reaction speed, increasing the risk of operational errors.

[0006] The amount of manual pressure applied is affected by the operator's physical strength, experience, and emotional fluctuations, making it difficult to guarantee uniform and consistent buckling every time. Insufficient pressure can lead to a loose connection between the buckle and the conveyor belt, reducing joint strength. Excessive pressure can deform the buckle or damage the conveyor belt, potentially leading to safety accidents such as belt breakage and material spillage.

[0007] To address these issues, the industry has recently attempted to improve button fastening efficiency through semi-automated improvements, such as introducing electric power assist devices or optimizing lever structures. However, these modifications still require manual intervention in key steps (such as buckle positioning and pressure adjustment), failing to completely eliminate core issues such as high labor intensity and poor quality consistency. Furthermore, the increased operational complexity of semi-automated equipment requires higher operator skills, further limiting its widespread adoption. Summary of the Invention

[0008] In view of the above situation, in order to overcome the defects of the existing technology, the present invention provides a fully automatic pneumatic button sewing machine, which effectively solves the problems of low efficiency, high labor intensity, unstable binding quality and rapid equipment wear when traditional manual pneumatic button sewing machines are used for binding metal U-shaped joints of coal mine conveyor belts.

[0040] The present invention proposes a fully automatic pneumatic button sewing machine: it includes a support frame 101, which serves as the main frame of the equipment and is welded with high-strength alloy steel. A slide rail 102 is provided on the top of the support frame 101, and the surface is quenched to improve wear resistance. Scale marks and multiple through holes are provided on both sides of the slide rail 102, which are convenient for operators to quickly locate the conveyor belt joint position and perform button sewing operations. A shell 104 is provided on the top of the slide rail 102, and a quick interface for an air pressure pipe is provided on the top of the shell 104. Two positioning plates 106 are provided inside the shell 104, and the two positioning plates 106 are arranged symmetrically front to back. The positioning plates 106 can provide support for the internal structure. A positioning block 204 is provided on the left side of the interior of the positioning plate 106, and the positioning block 204 cooperates with the slide rail 102. The positioning block 204 is slidably connected to the slide rail 102, which is convenient for disassembly and docking of the equipment.

[0041] A cylinder 105 is provided on the right side of the interior of the positioning plate 106. The cylinder 105 is rigidly connected to the positioning plate 106 through a flange to ensure the stability of the pressing process. A clamping assembly is provided on the left side of the cylinder 105. An upper pressure block 205 is provided on the top left side of the clamping assembly. The upper pressure block 205 is made of Cr12MoV mold steel, and the surface is carburized and quenched. A pressure sensor is integrated on the top to monitor the pressing force in real time and feed it back to the PLC control system. A lower pressure block 208 is provided on the bottom left side of the clamping assembly. The end of the piston rod 302 of the cylinder 105 is connected to the clamping assembly through a floating joint. The right side of the clamping assembly and the inner wall of the positioning plate 106 are slidably matched through a linear bearing to reduce movement resistance. An upper pressing block 205 and a lower pressing block 208 are symmetrically arranged at the top and bottom of the left side of the clamping assembly to form a counter-extrusion structure. An auxiliary top block 211 is provided on the rear side of the lower pressing block 208. The outer sides of the lower pressing block 208 and the auxiliary top block 211 are connected to the positioning block 204. The auxiliary top block 211 can assist in positioning the movement of the equipment. Before nailing, its top is inserted into the interior of the slide rail 102 to prevent the equipment from slipping during nailing.

[0042] An adjusting box 212 is provided on the top right side of the positioning block 204. A rectangular adjusting box 212 is fixed to the top right side of the positioning block 204 by bolts. A control component is provided inside the adjusting box 212. A disc 310 is provided on the top of the control component. A pawl 406 is provided on the top of the disc 310. The pawl 406 is forged with high-strength aluminum alloy and has a wedge-shaped front end. A moving component is provided on the left side of the pawl 406 and an adjusting component is provided on the right side of the pawl 406. The control component drives the disc 310 to rotate back and forth, and drives the pawl 406 to move back and forth. The adjusting component adjusts the inclination angle of the pawl 406, and cooperates with the moving component to realize intermittent movement of the equipment back and forth, thereby reducing manual physical labor.

[0043] A clamping plate 108 is provided on the top of the support frame 101, and two locking handles 103 are provided on the top of the clamping plate 108. The two locking handles 103 are arranged symmetrically front to back, and the bottom of the locking handle 103 is threaded. Rotating the locking handle 103 can drive the clamping plate 108 to move downward, thereby clamping the belt.

[0044] The clamping assembly includes a cylindrical rod 201, a slide is provided on the outside of the cylindrical rod 201, and a frame 107 is slidably connected to the outside of the slide. The frame 107 can provide support for the movement of the slide to ensure the stability of the movement of the cylindrical rod 201. The cylindrical rod 201 is connected to the left side of the cylinder 105, and the piston rod 302 of the cylinder 105 is in an extended state. The cylindrical rod 201 is located at the rightmost end of the stroke. The front end of the cylindrical rod 201 is provided with a third connecting rod 206, and the bottom of the third connecting rod 206 is provided with a fourth connecting rod 207. The left side of the fourth connecting rod 207 is slidably connected to the lower pressure block 208. The middle part of the cylindrical rod 201 is provided with a first connecting rod 202, and the top of the first connecting rod 202 is provided with a second connecting rod 203. The left side of the second connecting rod 203 is slidably connected to the upper pressure block 205. When the cylinder 105 receives the command, the first connecting rod 202 and the third connecting rod 206 are driven to move to the left through the cylindrical rod 201. At the same time, the angle between the first link 202 and the third link 206 also changes, thereby driving the second link 203 to rotate downward around its rotating axis. Since the upper pressure block 205 can only move vertically, the upper pressure block 205 can move vertically downward. The third link 206 drives the fourth link 207 to rotate, thereby driving the lower pressure block 208 to move vertically upward and extend from the inside of the slide rail 102. The belt end can be fastened by the cooperation of 205 and the lower pressure block 208. A driven rod 209 is provided on the rear side of the cylindrical rod 201, and a swing rod 210 is provided at the bottom of the driven rod 209. The left side of the swing rod 210 is slidably connected to the auxiliary top block 211. The cylindrical rod 201 drives the driven rod 209 to move, and can simultaneously pull the swing rod 210 to rotate, driving the auxiliary top block 211 vertically upward by one end distance, inserting the top of the auxiliary top block 211 into the interior of the slide rail 102 to position the equipment.

[0045] The control component includes a rectangular tube 301, which is connected to the positioning block 204. A piston rod 302 is provided inside the rectangular tube 301, and the bottom of the piston rod 302 is fixedly connected to the auxiliary top block 211. When the auxiliary top block 211 moves up and down, it can drive the piston rod 302 to move inside the rectangular tube 301, discharge the gas inside the piston rod 302 or generate negative pressure inside the piston rod 302. A forked tube 303 is provided on the top of the piston rod 302, and a first solenoid valve 304 is provided at the bottom left side of the forked tube 303. A hollow tube 306 is provided on the right side of the first solenoid valve 304. The forked tube 303 can divert the discharged gas and circulate it separately according to specific circumstances. The first solenoid valve 304 can actively control whether there is gas circulation inside the hollow tube 306.

[0046] A connecting plate 307 is provided inside the hollow tube 306, a rack 308 is provided on the left side of the connecting plate 307, a gear 309 is provided on the rear side of the rack 308, and the top of the gear 309 is connected to the disc 310. When the first solenoid valve 304 is opened and gas enters the inside of the hollow tube 306, the connecting plate 307 can be pushed to move backward, pulling the rack 308 to move backward, and the rack 308 drives the meshing gear 309 to rotate, thereby driving the disc 310 to rotate, realizing the movement of the pawl 406 from front to back. Conversely, when the gas inside the hollow tube 306 is extracted, the pawl 406 can be moved from front to back.

[0047] The adjustment component includes a moving rod 401, the left side of the moving rod 401 is connected to the rack 308, the side of the rack 308 is fixedly connected to the moving rod 401, and a moving frame 402 is provided on the top of the moving rod 401. When the rack 308 moves, the moving rod 401 and the moving frame 402 can be driven to move. A sealing tube 407 is provided on the top of the moving frame 402, and an electromagnet 403 is provided on the right side of the inside of the sealing tube 407. The electromagnet 403 can actively control the change of the magnetic pole. A fixed magnet 404 is provided on the left side of the inside of the sealing tube 407. When the magnetic pole of the electromagnet 403 changes, it can actively push the fixed magnet 404 in the sealing tube 407. The fixed magnet 404 can move left and right, a spring is provided between the electromagnet 403 and the fixed magnet 404, a slider 405 is provided on the left side of the fixed magnet 404, the slider 405 is slidably connected to the inside of the pawl 406, the slider 405 can slide inside the pawl 406, and the fixed magnet 404 can move with the movement of the pawl 406, so that the angle of the corresponding pawl 406 can be controlled, and a second solenoid valve 305 is provided on the rear side of the sealing tube 407, and the rear side of the second solenoid valve 305 is connected to the bifurcated tube 303. The air intake inside the sealing tube 407 can also be changed by controlling the on-off condition of the second solenoid valve 305, thereby changing the extended length of the fixed magnet 404.

[0048] A second ratchet 502 is provided on the left side of the pawl 406, and a first ratchet 501 is provided on the top of the second ratchet 502. A first electric push rod 503 is provided on the left side of the first ratchet 501, and a second electric push rod 504 is provided on the left side of the second ratchet 502. The first electric push rod 503 and the second electric push rod 504 are connected to the slide rail 102. The extension and contraction amount of the first electric push rod 503 is controlled to change the position of the first ratchet 501, and the extension and contraction amount of the second electric push rod 504 is controlled to change the position of the second ratchet 502, thereby switching the pawl 406 to cooperate with the first ratchet 501 and the first ratchet 501 respectively.

[0049] When the pawl 406 moves from front to back, since the direction of the first ratchet 501 matches the moving direction of the pawl 406, the pawl 406 will mesh with the first ratchet 501. After meshing, the pawl 406 applies a backward force to the first ratchet 501, and the first ratchet 501 is fixed on the relevant parts of the device, thereby driving the device as a whole to move backward. After the pawl 406 completes the cooperation with the first ratchet 501 and moves the device backward, the position of the pawl 406 needs to be adjusted so that it is located at the rear position close to the second ratchet 502. When the pawl 406 moves from back to front, since the direction of the second ratchet 502 matches the moving direction, the pawl 406 will mesh with the second ratchet 502. After meshing, the pawl 406 applies a forward force to the second ratchet 502, and the second ratchet 502 is fixed on the device, driving the device as a whole to move forward.

[0050] During use: the cylinder 105 is extended and retracted to drive the upper pressing block 205 and the lower pressing block 208 to move inward at the same time through the clamping assembly to perform the buttoning operation. After the buttoning is extruded, the auxiliary top block 211 descends, the first solenoid valve 304 opens, and the gas enters the hollow tube 306, pushing the connecting plate 307 to move backward, pulling the rack 308 to move backward, driving the gear 309 to rotate, and then driving the disc 310 to rotate clockwise, so that the pawl 406 moves from front to back, the first solenoid valve 304 is closed, and the second solenoid valve 305 opens, negative pressure is generated in the sealing tube 407, the fixed magnet 404 moves inward, pulling the pawl 406 to release the engagement with the second ratchet 502, and the first solenoid valve 304 continues to open, driving the pawl 406 to move back and forth, cooperating with the movement of the fixed magnet 404, so that the pawl 406 intermittently engages with the second ratchet 502, and the upper pressing block 205 and the lower pressing block 208 approach each other. After nailing once, the device is driven to move a distance to the front side, and then the above operation is repeated to complete the fully automatic nailing operation.

[0051] The cylinder 105 drives the clamping assembly to drive the upper pressure block 205 and the lower pressure block 208 to move to achieve button fastening. The first solenoid valve 304, the second solenoid valve 305, the connecting plate 307, the rack 308, the gear 309, the disc 310 and other components cooperate to realize the reciprocating and intermittent movement of the pawl 406, driving the equipment to move forward automatically, realizing fully automatic button fastening operation, greatly improving production efficiency, reducing manual operation and reducing labor intensity. The pawl 406 intermittently cooperates with the second ratchet 502, driving the equipment forward a fixed distance after each button fastening, which can accurately control the spacing of the buttons, ensure the quality and consistency of the buttons, and meet the product's requirements for the button position. The auxiliary top block 211 descends when the button is fastened, and rises and inserts into the slide rail 102 when the equipment needs to be moved to position the equipment, ensuring the stability of the equipment during movement and avoiding the impact of the button fastening quality due to the shaking of the equipment.

[0052] When the shell 104 moves to the frontmost side, the first electric push rod 503 extends, driving the first ratchet 501 to extend; the second electric push rod 504 contracts, and the second ratchet 502 is hidden inside, controlling the clamping assembly to move slightly, driving the pawl 406 to move back and forth. Since the directions of the first ratchet 501 and the second ratchet 502 are opposite, and the pawl 406 now moves from back to front, the shell 104 is pulled to move automatically to the rear side, and no buttoning operation is performed; the clamping assembly can also be controlled to operate normally, and the place where the buttoning is completed can be reinforced for the second time.

[0053] When the housing 104 moves to the front, the first and second electric push rods 503 and 504 adjust the positions of the first and second ratchet teeth 501 and 502, allowing the pawl 406 to automatically drive the housing 104 to move backward, resetting the device and facilitating the next button-stitching operation. At the same time, a secondary reinforcement can be performed on the completed button-stitching area to further improve the firmness of the button and ensure product quality. This step provides two operating modes: one for device reset and the other for secondary reinforcement, increasing the operational flexibility of the device and allowing selection based on actual production needs to meet different production scenarios and quality requirements.

[0054] Specifically, the cylinder 105 drives the clamping assembly to drive the upper pressing block 205 and the lower pressing block 208 to move to achieve button fastening. The first solenoid valve 304, the second solenoid valve 305, the connecting plate 307, the rack 308, the gear 309, the disc 310 and other components cooperate to realize the reciprocating and intermittent movement of the pawl 406, driving the equipment to automatically move forward to achieve fully automatic button fastening, greatly improving production efficiency. The fully automatic button fastening operation reduces manual operation and reduces labor intensity. The pawl 406 intermittently cooperates with the second ratchet 502 to drive the equipment forward a fixed distance after each button fastening, which can accurately control the spacing of the buttons and meet the product's requirements for the button position, ensuring the quality and consistency of the buttons. The auxiliary top block 211 drops when the button is fastened. When the device is to be moved, it is lifted and inserted into the slide rail 102 to position the device to ensure the stability of the device during movement. Accurate positioning of the device can avoid affecting the quality of the button fastening due to shaking of the device. When the shell 104 moves to the front side, the positions of the first ratchet 501 and the second ratchet 502 are adjusted by the first electric push rod 503 and the second electric push rod 504, so that the pawl 406 can drive the shell 104 to move automatically to the rear side, thereby resetting the device and facilitating the start of the next button fastening operation. The place where the button is fastened can be reinforced for the second time to further improve the firmness of the button fastening. Two operation modes of device reset and secondary reinforcement are provided, which increase the operational flexibility of the device and can be selected according to actual production needs to meet different production scenarios and quality requirements.
