Description

Technical Field

[0001] The invention relates to the field of belt gear punching machines, in particular to automatic and continuous belt gear punching equipment. Background Art

[0002] The belt tooth punching machine is mainly used to punch teeth on both ends of the belt to facilitate the connection of the two ends of the belt together, making the belt connection in a circle, that is, the head and tail of the belt need to be connected together. The head and tail of the belt are generally hot-pressed and welded by a splicing machine to finally produce a belt with the head and tail connected.

[0003] There are several ways to punch teeth for belts in the prior art: 1. Straight teeth: punch multiple teeth at both ends of the belt, align these teeth one by one, and then connect them according to the welding process. It is usually suitable for occasions that do not need to bear extremely large loads or have specific requirements for the thickness of the belt; 2. Oblique teeth: punch multiple teeth set obliquely at both ends of the belt, align these teeth one by one, and then connect them according to the welding process. The oblique teeth set in this way can obtain a larger area of ​​the joint surface under the same width, which is suitable for occasions that require strong connection and high load capacity or have specific requirements for the width of the belt; 3. Double-layer teeth: first layer the two ends of the belt, and punch out two rows of teeth at a specific distance. When punching teeth, the bottom surface of one end of the belt is used as the upper layer, and the surface of the other end is used as the lower layer, so that the teeth can be correctly aligned in the subsequent melting process. The double-layer tooth joint can provide a stronger connection and better load distribution, which is suitable for occasions that bear large loads and require high transmission efficiency and have thicker belts.

[0004] The existing Chinese utility model patent with publication number CN214293485U discloses a wide-width tooth punching machine for industrial conveyor belts, including a conveyor belt laying platform, a conveyor belt tooth punching mechanism and two pressing mechanisms, the conveyor belt laying platform is installed between two vertical plates, a screw rod is rotatably installed between the two vertical plates, the conveyor belt tooth punching mechanism is slidably installed above the conveyor belt laying platform through two horizontal beams, the screw rod is located between the two horizontal beams, the pressing mechanism includes a pressing beam and a plurality of pressing plates, the conveyor belt tooth punching mechanism includes a cutting die and a cutting die telescopic mechanism, and a nut seat is provided on the cutting die telescopic mechanism. The utility model can realize the full width of the conveyor belt by slidingly installing the conveyor belt tooth punching mechanism between the two horizontal beams, and at the same time, the nut seat and the screw rod are matched to realize the axial translation of the cutting die telescopic mechanism along the screw rod, so as to realize the full width of the conveyor belt. Therefore, it can be applied to conveyor belts of various widths, has a wide range of applications, and can effectively improve the tooth punching efficiency and tooth punching accuracy of the conveyor belt.

[0005] However, in the above structure, the wide-width gear punching machine also has the following defects: 1. The movement of the belt needs to be controlled during the punching process, and the length needs to be measured manually while moving, resulting in low punching efficiency.

[0006] 2. Bevel teeth on belts require preliminary processing of the belts (both ends need to be cut into bevel edges), which makes the bevel teeth punching process more complicated. Moreover, the wide-width tooth punching machine cannot realize complex double-layer tooth punching processing operations (it is necessary to accurately control the height of the cutter's two cuts to avoid hitting the lower belt). The user needs to make additional processing for bevel teeth, which affects the tooth punching efficiency. When making double-layer teeth, it is necessary to purchase an additional double-layer tooth punching machine, which takes up the working area of ​​the factory.

[0007] 3. The wide-width gear punching machine adopts screw drive. This mechanism has a disadvantage. When the screw span is long, it will fall in the middle due to gravity, resulting in unsmooth operation. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide an automatic continuous belt toothing device in view of the deficiencies of the above-mentioned prior art. The toothing device can realize three processing methods: straight teeth, helical teeth and double-layer teeth, and controls the forward and backward movement of the belt through a traction mechanism to replace manual movement operations. At the same time, it can also realize length measurement and improve toothing efficiency. It adopts a gear rack mechanism for transmission and installs the rack on a reinforced tube to solve the problem of falling, thereby realizing stable toothing with ultra-long and wide width.

[0009] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an automatic continuous belt toothing device, comprising a frame, a belt laying platform arranged on one side of the frame, a toothing platform arranged on the frame, a belt toothing mechanism arranged above the toothing platform, and a toothing sliding mechanism for driving the belt toothing mechanism to slide along the X-axis direction of the frame, the belt toothing mechanism comprising a cutting die and a cutting die lifting mechanism for driving the cutting die to rise and fall along the Z-axis direction of the frame, a traction mechanism for moving the belt at the belt laying platform toward the Y-axis direction of the frame is provided at one end of the frame corresponding to the belt laying platform, the traction mechanism is used to pull the belt to the toothing platform to cooperate with the belt toothing mechanism for toothing, and send the toothed belt out from the end of the frame away from the belt laying platform.

[0010] By adopting the above technical scheme, a traction mechanism with Y-axis control is set up to realize the forward and backward movement of the belt, replacing the manual movement operation, and the length measurement work can also be realized. In addition, the automatic helical tooth punching operation can be realized by simultaneously controlling the tooth punching sliding mechanism to move the cutting die laterally along the X-axis and controlling the Y-axis to move the belt forward and backward. When in use, the worker only needs to position the belt on the laying platform, and the traction mechanism will pull the belt to the tooth punching platform along the Y-axis direction. The belt tooth punching mechanism will drive the cutting die to perform Z-axis lifting and tooth punching on the belt end on the lower tooth punching platform, and drive the cutting die to slide gradually along the X-axis laterally to automatically punch teeth through the tooth punching sliding mechanism. After one end is fully toothed, the belt is pulled to the end through the traction mechanism, and teeth are re-punched at the end, realizing automatic continuous tooth punching without manual intervention, improving production efficiency and processing accuracy, simplifying the helical tooth punching process, and reducing the difficulty of helical tooth punching.

[0011] The above-mentioned automatic continuous belt toothing equipment can be further configured as follows: the traction mechanism includes a first traction component arranged between the belt laying platform and the toothing platform and a belt traction motor driving the first traction component to rotate, the first traction component includes two first traction rollers relatively set up on the frame and rotating, and a feed gap for the belt to pass through is provided between the first traction rollers.

[0012] By adopting the above technical solution, the traction mechanism is configured as two first traction rollers that are relatively set and rotated, and then a belt traction motor is set to drive one of the first traction rollers to rotate, so that the belt is pulled to the toothing platform through the feeding gap between the two first traction rollers, thereby realizing stable automated Y-axis belt feeding.

[0013] The above-mentioned automatic continuous toothing equipment with belts can be further configured as follows: the traction mechanism also includes a second traction assembly arranged at one end of the toothing platform away from the first traction assembly, the second traction assembly includes two second traction rollers relatively set up and rotating on the frame, a discharge gap for the belt to pass through is provided between the second traction rollers, the first traction assembly and the second traction assembly are respectively arranged at both ends of the toothing platform, and the belt traction motor drives the first traction assembly and the second traction assembly to rotate synchronously through a synchronous belt transmission structure, a sprocket transmission structure or a gear transmission structure.

[0014] By adopting the above technical scheme, a second traction assembly is arranged at the other end of the tooth punching platform, so that the second traction roller forms a discharge gap for the belt to pass through, and the belt traction motor drives the first traction assembly and the second traction assembly to rotate synchronously at the same time, so that the belt at the tooth punching platform can be clamped by the second traction assembly at the other end after the teeth are punched at one end, so as to stably punch the teeth at the end, and at the same time, the belt with completed teeth is stably sent out of the frame through the second traction assembly, so as to realize stable automatic belt feeding.

[0015] The above-mentioned automatic continuous tooth punching equipment can be further configured as follows: the synchronous belt transmission structure includes a motor synchronous wheel arranged on the belt traction motor, an active synchronous wheel and a feed driven synchronous wheel coaxially arranged on one of the first traction rollers, and a discharge driven synchronous wheel arranged on one of the second traction rollers, an active synchronous belt is wound between the motor synchronous wheel and the active synchronous wheel, and a driven synchronous belt is wound between the feed driven synchronous wheel and the discharge driven synchronous wheel.

[0016] By adopting the above technical solution, the belt traction motor preferably uses a synchronous belt transmission structure for transmission. The motor synchronous wheel on the belt traction motor drives the active synchronous wheel on one of the first traction rollers to rotate through the active synchronous belt, and links the feed driven synchronous wheel to rotate, so that it drives the discharging driven synchronous wheel on one of the second traction rollers to rotate through the driven synchronous belt, thereby ensuring the synchronization of belt traction and improving the tooth punching accuracy.

[0017] The above-mentioned belt automatic continuous tooth-beating equipment can be further configured as follows: a gap adjustment mechanism is provided above the tooth-beating platform corresponding to the frame, and the gap adjustment mechanism includes an upper traction frame arranged above the tooth-beating platform, a gap adjustment cylinder arranged on the frame, and a rotatable adjustment rotating shaft arranged on the frame, the first traction roller and the second traction roller above the first traction assembly and the second traction assembly are installed on the upper traction frame, and the first traction roller and the second traction roller below are driven by a synchronous belt transmission structure. The output end of the gap adjustment cylinder is provided with a small torque arm, one end of the small torque arm is fixedly connected to the adjusting rotating shaft, and the other end is connected to the gap adjustment cylinder, and large torque arms are respectively provided at two ends of the upper traction frame corresponding to the adjusting rotating shaft, one end of the large torque arm is fixedly connected to the adjusting rotating shaft, and the other end is connected to the upper traction frame, and the upper traction frame is driven to rise and fall along the Z-axis direction through the gap adjustment cylinder, thereby controlling the width of the feeding gap and the discharging gap.

[0018] By adopting the above technical scheme, by setting a gap adjustment mechanism, the user can drive the small torque arm to rotate through the gap adjustment cylinder when punching teeth according to belts of different thicknesses. As the small torque arm rotates, the adjustment rotating shaft also rotates. Since the large torque arm is fixedly connected to the adjustment rotating shaft, the large torque arms at both ends will rotate around the adjustment rotating shaft. The rotation of the large torque arm drives the upper traction frame to rise and fall stably along the Z-axis direction without interfering with the punching of the cutting die. The upper traction frame is connected to the first traction roller and the second traction roller, so as to adjust the gap between these traction rollers and the belt. The first and second traction components are controlled to rotate by the belt traction motor below. The width adjustment of the feeding gap and the discharging gap can be achieved through the precise control of the gap adjustment cylinder, ensuring that there is an appropriate gap between the belt and the traction roller to avoid slipping or jamming of the belt during the tooth punching process. Once the required gap is reached, the cylinder stops moving, the upper traction frame and the traction roller assembly are fixed in a new position, and the belt tooth punching operation is ready. Preferably, the gap adjustment mechanism can also include a pressure sensor for real-time monitoring of the gap and fine-tuning to ensure precise control.

[0019] The above-mentioned belt automatic continuous tooth punching equipment can be further configured as follows: the cutting knife die lifting mechanism includes a cutting knife seat slidably mounted on the frame, a lifting mounting plate and a cutting knife Z-axis lifting motor arranged on the cutting knife seat, the cutting knife die is mounted on one end of the lifting mounting plate facing the tooth punching platform, the lifting mounting plate is slidably mounted on the cutting knife seat through a slider rail structure, a cutting knife lifting screw is provided at the cutting knife seat corresponding to the lifting mounting plate, the lifting mounting plate is threadedly connected to the cutting knife lifting screw through a screw slider, the cutting knife Z-axis lifting motor drives the cutting knife lifting screw to rotate through the cutting knife lifting synchronous belt, thereby controlling the cutting knife die to approach or move away from the tooth punching platform along the Z-axis direction of the frame.

[0020] By adopting the above technical scheme, the cutting die lifting mechanism realizes precise control of the cutting die along the Z-axis direction through the cutting die lifting screw and the cutting die Z-axis lifting motor. When in use, the cutting die Z-axis lifting motor rotates, and the cutting die lifting synchronous belt drives the cutting die lifting screw to rotate. Since the cutting die lifting screw is restricted in height change, the screw slider screwed to the outside of the cutting die lifting screw moves up and down along the Z-axis direction of the cutting seat, thereby controlling the cutting die to approach or move away from the tooth punching platform along the Z-axis direction of the frame, and teeth the belt on the tooth punching platform. The Z-axis height position of the cutting die is precisely controlled through the precise transmission of the cutting die Z-axis lifting motor and the cutting die lifting screw. In addition to meeting the requirements of ordinary single-layer tooth operations, double-layer tooth punching operations can be realized by changing the height of the cutting die each time, and multiple sets of tooth punching processes can be realized on one tooth punching equipment.

[0021] The above-mentioned automatic continuous tooth punching equipment for belts can be further configured as follows: the cutting knife mold includes a knife holder seat installed on a lifting mounting plate, a cutting knife arranged at the bottom of the knife holder seat and a pressing plate arranged below the knife holder seat, the pressing plate is provided with a clearance groove for the cutting knife to pass through, a plurality of positioning pins are arranged between the pressing plate and the knife holder seat, the knife holder seat is provided with a pressing hole for the positioning pins to pass through, and the positioning pins are each sleeved with a spring, one end of the spring is against the pressing plate, and the other end is against the knife holder seat, so that there is a gap between the cutting knife and the pressing plate.

[0022] By adopting the above technical solution, the clearance between the pressure plate and the tool holder is controlled by the positioning pin and the spring mechanism in the design of the cutting die, so that the cutting knife teeth are first flattened by the pressure plate before teeth are punched, thereby improving the quality of teeth punching.

[0023] The above-mentioned belt automatic continuous tooth punching equipment can be further configured as follows: the tooth punching sliding mechanism includes a rack arranged in the X-axis direction of the frame and an X-axis sliding motor arranged on the tool holder seat, the tool holder seat is slidably installed on the frame through a slider rail structure, the rack is arranged on one side of the frame, and a reinforcing tube supporting the rack is provided below, the rack portion extends out of the outside of the reinforcing tube, and an X-axis transmission gear meshing with the rack is provided after one end of the X-axis sliding motor passes through the tool holder seat, and the X-axis sliding motor drives the tool holder seat to slide along the X-axis direction.

[0024] By adopting the above technical solution, the tooth punching sliding mechanism realizes the sliding of the tool holder along the X-axis direction through the rack and the X-axis sliding motor, thereby realizing automatic continuous tooth punching. By adopting the gear rack mechanism transmission, the rack is installed on the reinforced tube to solve the problem of falling, so that it can adapt to the ultra-wide belt tooth punching operation.

[0025] The above-mentioned automatic continuous belt tooth punching equipment can be further configured as follows: the belt laying platform is provided with a plurality of installation grooves along the X-axis direction, two belt positioning blocks are provided above the belt laying platform, the belt positioning blocks are fixedly connected to the installation grooves by fasteners, a step-type stopper is provided between the belt positioning block and the belt laying platform, a laying cavity for fixing the belt is formed between the belt positioning blocks on both sides, and the step-type stopper cooperates with the fastener to limit the thickness of the laying cavity.

[0026] By adopting the above technical scheme, the belt positioning block and the stepped stopper are used in combination to form a laying cavity which limits the width of the belt and the thickness of the belt, thereby stably laying the belt on the belt laying platform on the belt laying platform, thereby improving the stability of the Y-axis belt during conveying and avoiding belt deviation.

[0027] The above-mentioned automatic continuous tooth punching device can be further configured as follows: the frame is also provided with a control host, and the control host is used to control the operation of the belt traction motor, the X-axis sliding motor and the cutter Z-axis lifting motor.

[0028] By adopting the above technical solution, the belt traction motor, X-axis sliding motor and cutter Z-axis lifting motor are preferably servo motors. The control host controls the belt traction motor, X-axis sliding motor and cutter Z-axis lifting motor through a software program. Through CNC programming, the X\Y\Z 3-axis linkage operation can be accurately controlled, thereby improving operational convenience, realizing automatic control, and adapting to belt processing of different specifications and different toothing modes.

[0029] Beneficial effects of the present invention: 1. Improved automation: Through the automated traction mechanism and tooth punching mechanism, the belt can be automatically and continuously punched, which significantly reduces manual operation and labor intensity.

[0030] 2. Improve the efficiency of tooth punching: The equipment can automatically complete the conveying, positioning, tooth punching and sending of the belt, without the need for manual measurement while moving, which greatly improves the efficiency of the tooth punching operation.

[0033] 5. Solve the stability problem of long spans: Use gear rack transmission instead of ball screw to solve the falling problem under long spans and ensure the stable operation of the equipment.

[0034] 6. Simplify the bevel gear punching process: Bevel gear punching is achieved through automated control, which simplifies the cumbersome steps in the traditional bevel gear punching process and reduces the difficulty of bevel gear punching.

[0035] 7. Increase the usable area of ​​the workshop: Since the equipment can realize a variety of tooth punching methods, users do not need to purchase multiple devices for different tooth punching needs, thus reducing the occupied area.

Front bottom teeth punching: The cutting die lifting mechanism adjusts the cutting die to the bottom design height. The cutting die moves along the X-axis direction under the drive of the X-axis sliding motor and cooperates with the cutting die Z-axis lifting motor to punch the bottom straight teeth. 6. Belt positioning adjustment: The belt traction motor is started, and the belt is pulled in the Y-axis direction to the upper tooth punching height. The belt is correctly aligned through positioning adjustment for upper tooth punching; 7. Punching teeth on the front upper layer: The cutting die lifting mechanism adjusts the cutting die to the upper design height (there is a certain height difference relative to the bottom layer). At the same time, to avoid punching through the belt, the operator can put a waste belt between the bottom layer and the upper layer, and then move along the X-axis direction on the upper layer to cooperate with the Z-axis lifting motor to punch the upper teeth, forming a double-layer tooth structure; 8. Flip the front and back sides of the belt: lift the upper traction frame through the gap adjustment cylinder, then manually take out the belt with the front teeth and flip it over, and place the untoothed part at the tail end on the belt laying platform corresponding to the toothed platform, with the front and back sides opposite to each other: 9. Post-tooth punching operation: The belt traction motor is started, the first and second traction roller assemblies rotate, the flipped belt is transported to the tooth punching platform and the tooth punching operation of steps 5-7 is repeated to ensure that the double-layer teeth at the front and rear ends are closely connected; 10. Belt delivery: After the double-layer teeth are punched, lift the upper traction frame through the gap adjustment cylinder to take out the belt with the teeth punched.
