Description

Technical Field

[0001] This utility model relates to the technical field of belt splicing equipment, specifically to an automatic telescopic feeding punch splicing integrated machine. Background Technology

[0002] Belt splicing machines, also known as belt jointing machines, hot presses, or hot melt machines, are devices that heat-press two belts together to create a seamless connection between two independent belt segments. Common types include PU polyurethane industrial belt splicers, water-cooled fixed industrial belt splicing machines with supports, and PVC conveyor belt splicing machines. They primarily utilize high temperature, pressure, and cooling technology to melt and join lightweight plastic belt joints such as PVC, PU, ​​and PE. Pneumatic hot presses also employ two heating plates simultaneously, utilizing automatic temperature control, pressurized airbags, and an automatic rapid cooling system to meet the physical characteristics and process requirements of various belt materials. Their unique heating design ensures that the processed products have smooth, flexible, and durable joints. Air-cooled belt splicing machines, on the other hand, are compact, small in size, stable in operation, and easy to use, producing smooth and aesthetically pleasing belts with no obvious traces at the joints, improving both appearance and strength. The price of belt splicing machines varies depending on the specifications and type, ranging from several hundred yuan to tens of thousands of yuan.

However, this technology can only connect different belts and cannot connect the two ends of a single belt, so its applicability is limited. Therefore, this technology still has some room for improvement. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an automatic telescopic feeding punching and connecting machine that addresses the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic telescopic feeding punching and connecting machine, including a frame and a conveying device disposed within the frame, wherein the frame is provided with a connecting mechanism above the conveying device, characterized in that: the frame is provided with lifting clamping mechanisms on both sides of the connecting mechanism, and a rotating device is provided on one side of the clamping structure to enable the material to rotate and fold to the connecting mechanism.

[0006] By adopting the above technical solution, the machine frame is equipped with lifting clamping mechanisms on both sides of the connecting mechanism, which can clamp and position both ends of the material. Furthermore, a rotating device is provided on one side of the clamping structure, which can cause the material to rotate and fold to the connecting mechanism, thereby realizing automated bending processing of the material, increasing the scope of application, reducing manual intervention, and improving production efficiency.

[0007] The aforementioned automatic telescopic feeding punching and connecting machine can be further configured as follows: the conveying device includes a fixed conveying end and a movable conveying end that can reciprocate along the length of the conveying device on one side of the fixed conveying end; the clamping mechanism includes a lower clamping plate that is initially set at the bottom of the movable conveying end of the frame; the lower clamping plate is hinged to an upper clamping plate at both ends; a first driving source is provided on one side of the upper clamping plate; and a transmission component is provided between the first driving source and the upper plate to enable the first driving source to control the clamping state of the upper clamping plate.

[0008] Using the above technical solution, the conveying device consists of a fixed conveying end and a movable conveying end that can reciprocate along the length of the conveying device. In the initial state, the lower clamping plate is set at the bottom of the movable conveying end, and the upper clamping plates are hinged at both ends. The upper clamping plate is equipped with a first drive source on one side and the clamping state of the upper clamping plate is controlled by the transmission component. During processing, the material of the conveying device is transported to the clamping plate at the end, and one end of the material is clamped. After clamping, the movable conveying section is retracted to avoid interference with the clamping of the other end. When the movable conveying end is retracted to one end, the clamping plate on the other side clamps the other end of the material. The clamping plates at both ends are then raised to the level of the connecting mechanism. The clamping plates at both ends rotate and fold the toothed ends into the connecting mechanism for processing, thus completing automated production.

[0009] The aforementioned automatic telescopic feeding punching and connecting machine can be further configured such that: the transmission component includes a transmission gear located at the hinge of the upper clamping plate, the first driving source is a telescopic cylinder, and the first driving source is provided with a transmission rack at the telescopic end, wherein the transmission rack meshes with the transmission gear.

[0010] Using the above technical solution, the transmission component adopts a transmission gear set at the hinge of the upper clamping plate, which works in conjunction with the telescopic cylinder as the first driving source and the transmission rack at its telescopic end. When the telescopic cylinder extends or retracts, it drives the transmission rack to move. Since the transmission rack meshes with the transmission gear, the linear motion of the transmission rack can be smoothly converted into the rotation of the transmission gear, thereby realizing the opening and closing action of the upper clamping plate, so that the upper clamping plate can quickly and stably clamp or release the material.

[0011] The aforementioned automatic telescopic feeding punching and connecting machine can be further configured such that: the rotating device includes a rotating shaft fixedly installed at both ends of the lower clamping plate, and a second driving source is connected to any end of the rotating shaft. The second driving source can drive the clamped material to rotate to the connecting mechanism through the rotating shaft.

[0012] By adopting the above technical solution, the rotating device can rotate the clamped material to the connecting mechanism to connect and process the two ends of the material by means of rotating shafts fixedly installed at both ends of the lower clamping plate and connecting one end of the rotating shaft to the second drive source.

[0013] The aforementioned automatic telescopic feeding punching and connecting machine can be further configured as follows: the frame is provided with movable guide rails on both sides of the lower clamping plate, the movable guide rails are slidably provided with sliders, the end of the movable guide rail on either side is provided with a third driving member, the third driving member can drive the slider to move vertically back and forth, a connecting plate is provided on one side of the slider, a base plate is installed on the connecting plate, the base plate is vertically arranged on the connecting plate to form an L shape, a fixing member is provided on the rotating shaft, a rotating bearing is provided between the fixing member and the rotating shaft, and the fixing member and the base plate are connected by a mounting plate.

[0014] Using the above technical solution, movable guide rails are set on both sides of the lower clamping plate of the frame, and sliders are slidably set on the guide rails. With the cooperation of the third driving component at the end, the sliders can be driven to move vertically back and forth. When the clamping plates at both ends are clamped, the third driving component drives the material to move to the horizontal height of the connecting mechanism for processing. The fixed component sleeved on the rotating shaft is connected to the rotating shaft through a rotating bearing, which not only ensures that the rotating shaft can rotate smoothly, but also ensures the stability and reliability of the rotating device during operation.

[0015] The aforementioned automatic telescopic feeding punching and connecting machine can be further configured such that: the fixed conveying end includes a plurality of conveying plates arranged along the extension direction of the frame, a plurality of fixed rollers are provided between the conveying plates, and a fixed plate is provided at the top between the conveying plates.

[0016] The above technical solution employs several conveying plates arranged along the extension direction of the frame, which provide stable support for the material conveying. Several fixed rollers arranged between the conveying plates effectively reduce the friction between the material and the conveying device, allowing the material to slide more smoothly on the conveying end, improving conveying efficiency and reducing energy consumption. The fixed plates arranged at the top between the conveying plates further enhance the stability and rigidity of the conveying end structure, preventing the conveying plates from deforming or shaking during material conveying, thereby ensuring the stability and reliability of material conveying.

[0017] The aforementioned automatic telescopic feeding punching and connecting machine can be further configured as follows: the movable conveying end includes several shaft seats disposed between the conveying plates, several movable shafts are inserted inside the shaft seats, a fourth driving member is provided at the end of the movable shaft, a movable block is sleeved on the movable shaft, a slide rail is provided between the conveying plates, the slide rail extends in the direction of the connecting structure, a slide plate is slidably connected to the slide rail, a movable plate is provided between the slide plates, a movable roller is provided at the bottom of the movable plate, the movable plate is fixedly connected to the movable block to enable the fourth driving member to drive the movable plate to move axially back and forth, and a transmission belt is sleeved on the outer periphery of the movable plate, the fixed plate, the movable roller, and the fixed roller.

[0018] Using the above technical solution, the fourth driving component drives the moving shaft to rotate, thereby driving the moving block to move. The sliding connection between the slide rail and the sliding plate, and the fixed connection between the moving plate and the moving block, ensure that the moving plate can move axially back and forth along the slide rail. Under normal conditions, the moving plate is in an extended state and abuts against the lower clamping plate on one side, while the lower clamping plate on the other side is placed below the moving plate. When one end of the material is transported to the abutting lower clamping plate for clamping, the moving plate is also equipped with a sensor to detect the end of the material. When the sensor detects the end of the material, the moving plate begins to retract, retracting to the side of the clamping plate originally placed below the moving plate. The clamping plate then clamps the material to fix both ends, and the clamping plates at both ends then move up and down and rotate for processing.

[0019] The aforementioned automatic telescopic feeding punching and connecting machine can be further configured as follows: the frame is provided with a truss and a worktable, the connecting mechanism includes a lifting cylinder passing through the truss, an upper mold machine is fixedly installed at the end of the lifting cylinder, a lower mold machine is fixedly installed on the top of the worktable, and the frame is provided with a storage cavity below the worktable for storing materials after the moving plate retracts towards the fixed plate.

[0020] Using the above technical solution, the lifting cylinder installed in the truss drives the upper mold machine, which cooperates with the lower mold machine fixed on the top of the workbench. The two side clamps are raised and lowered to the horizontal position of the lower mold machine to realize the connection and processing of materials. When the moving plate retracts towards the fixed plate, the material can be stored in the storage cavity, which enables the equipment to process long materials and avoids the edges from peeling at both ends during material processing due to excessive length, thus ensuring the quality and stability of processing.

[0021] The aforementioned automatic telescopic feeding punching and connecting machine can be further configured as follows: the top of the conveyor plate is provided with several fixed frames, the fixed frames are provided with connecting shafts, the other end of the connecting shaft is provided with a connector, the other end of the connector is provided with a guide plate, the guide plate is placed on the surface of the transmission belt, the conveyor plate is provided with pressure roller seats at the moving plate, pressure roller shafts are rotatably connected between the pressure roller seats, and several pressure rollers are sleeved on the pressure roller shafts.

[0022] By adopting the above technical solution, the fixed frame set on the top of the conveyor plate, as well as the connecting shaft, connector and guide plate that pass through it, can accurately guide the material on the transmission belt. The pressure roller can apply appropriate pressure to the material on the transmission belt to ensure that there is sufficient friction between the material and the transmission belt. At the same time, after the moving plate retracts, the pressure roller can press the edge of the material, ensuring that the material will not fall off due to its own weight, and enhancing the stability of the clamping plate.

[0023] The aforementioned automatic telescopic feeding punching and connecting machine can be further configured such that: a punching machine is provided on one side of the frame at the fixed conveying end, a winding machine is provided on one side of the punching machine, and an opening for material to pass through is provided on the side of the frame facing the winding machine.

[0024] By adopting the above technical solution, a toothing machine is set on the side of the frame located at the fixed conveying end, which prompts the material to be toothed before being connected, thus realizing the close connection between the feeding and toothing processes. The opening for material to pass through is set on the side of the frame facing the coiler, so that the material can smoothly enter the toothing machine for toothing and then be transferred from the coiler to the fixed conveying end for connection processing.

[0025] The beneficial effects of this utility model are as follows: The frame is provided with lifting clamping mechanisms on both sides of the connecting mechanism, and a rotating device is provided on one side of the clamping structure, which can cause the material to rotate and fold to the connecting mechanism, thereby realizing the automated bending processing of the material.

Detailed Implementation

[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0028] like Figure 1-4The present invention provides the following technical solution: an automatic telescopic feeding punching and connecting machine, including a frame 1 and a conveying device 2 disposed within the frame 1. A connecting mechanism 3 is provided above the conveying device 2 on the frame 1. Liftable clamping mechanisms 4 are provided on both sides of the connecting mechanism 3 on the frame 1. A rotating device 5 is provided on one side of the clamping structure to cause the material to rotate and fold to the connecting mechanism 3. By providing liftable clamping mechanisms 4 on both sides of the connecting mechanism 3 on the frame 1, the two ends of the material can be clamped and positioned. Furthermore, the rotating device 5 on one side of the clamping structure causes the material to rotate and fold to the connecting mechanism 3, thus realizing automated bending processing of the material, increasing the scope of application, reducing manual intervention, and improving production efficiency. The conveying device 2 includes... The conveying device 2 consists of a fixed conveying end 6 and a movable conveying end 7 that can reciprocate along the length of the conveying device 2, with one side of the fixed conveying end 6 being movable. The clamping mechanism 4 includes a lower clamping plate 8 initially positioned at the bottom of the movable conveying end 7, with upper clamping plates 9 hinged at both ends of the lower clamping plate 8. A first drive source 10 is provided on one side of the upper clamping plate 9. The first drive source 10 is connected to the upper plate via a transmission assembly, enabling the first drive source 10 to control the clamping state of the upper clamping plate 9. The conveying device 2 is composed of a fixed conveying end 6 and a movable conveying end 7 that can reciprocate along the length of the conveying device 2. In the initial state, the lower clamping plate 8 is positioned at the bottom of the movable conveying end 7, with the upper clamping plates 9 hinged at both ends. The first drive source 10 is provided on one side of the upper clamping plate 9 and is connected to the upper plate via a transmission assembly. The clamping state of the upper clamping plate 9 is controlled. During processing, the two pieces of material are transported to the end clamping plate by the conveying device, and one end of the material is clamped. After clamping, the moving conveyor section is retracted to avoid interference with the clamping of the other end. When the moving conveyor end 7 retracts to one end, the clamping plate on the other side clamps the other end of the material. The clamping plates at both ends are then raised to the level of the connecting mechanism 3. The toothed ends of the clamping plates at both ends are rotated and folded into the connecting mechanism 3 for processing, completing automated production. The transmission component includes a transmission gear 11 set at the hinge of the upper clamping plate 9. The first drive source 10 is a telescopic cylinder. The first drive source 10 is provided with a transmission rack 12 at the telescopic end. The transmission rack 12 meshes with the transmission gear 11. The transmission component adopts a transmission rack 11 set at the hinge of the upper clamping plate 9. The moving gear 11, in conjunction with the telescopic cylinder serving as the first drive source 10 and its telescopic end transmission rack 12, causes the transmission rack 12 to move when the telescopic cylinder extends or retracts. Since the transmission rack 12 meshes with the transmission gear 11, the linear motion of the transmission rack 12 is smoothly converted into the rotation of the transmission gear 11, thereby realizing the opening and closing action of the upper clamping plate 9. This allows the upper clamping plate 9 to quickly and stably clamp or release materials. The rotating device 5 includes rotating shafts 13 fixedly installed at both ends of the lower clamping plate 8. A second drive source 14 is connected to either end of the rotating shaft 13. The second drive source 14 can drive the clamped material to rotate to the connecting mechanism 3 via the rotating shaft 13. The rotating device 5 utilizes the rotating shafts 13 fixedly installed at both ends of the lower clamping plate 8.The rotating shaft 13 at one end is connected to the second drive source 14, enabling the clamped material to be rotated to the connecting mechanism 3 for connection processing during material conveying and processing.

A third driving member 17 is provided at the end of the movable guide rail 15 on either side, and the third driving member 17 can drive the slider 16 to move vertically and reciprocally. A connecting plate 18 is provided on one side of the slider 16, and a base plate 19 is mounted on the connecting plate 18. The base plate 19 is vertically mounted on the connecting plate 18 to form an L-shape. A fixing member 20 is sleeved on the rotating shaft 13, and a rotary bearing 21 is provided between the fixing member 20 and the rotating shaft 13. The fixing member 20 and the base plate 19 are connected by a mounting plate 22. Movable guide rails 15 are provided on both sides of the lower clamping plate 8 of the frame 1, and sliders 16 are slidably mounted on the guide rails. The slider 16, in conjunction with the third drive component 17 at the end, can drive the slider 16 to move vertically back and forth. When the clamping plates at both ends hold the material, the third drive component 17 drives the material to the horizontal height of the connecting mechanism 3 for processing. The fixing component 20 sleeved on the rotating shaft 13 is connected to the rotating shaft 13 through the rotating bearing 21, which not only ensures the smooth rotation of the rotating shaft 13, but also ensures the stability and reliability of the rotating device 5 during operation. The fixed conveying end 6 includes several conveying plates 23 arranged along the extension direction of the frame 1. Several fixed rollers 24 are provided between the conveying plates 23, and a fixing plate 25 is provided at the top between the conveying plates 23. The several conveying plates 23 arranged along the extension direction of the frame 1 provide stable support for the conveying of materials. The fixed rollers 24 arranged between the conveyor plates 23 effectively reduce the friction between the material and the conveying device 2, allowing the material to slide more smoothly on the conveying end, improving conveying efficiency and reducing energy consumption. The fixed plate 25 arranged at the top between the conveyor plates 23 further enhances the stability and rigidity of the conveying end structure, preventing the conveyor plates 23 from deforming or shaking during material conveying, thereby ensuring the stability and reliability of material conveying. The movable conveying end 7 includes several bearing seats 26 arranged between the conveyor plates 23, with several movable shafts 27 passing through the bearing seats 26. The ends of the movable shafts 27 are provided with fourth driving members 28, and movable blocks 29 are sleeved on the movable shafts 27. A slide rail 30 is provided between the conveyor plates 23, extending towards the connecting structure. A slide rail 30 is slidably connected to a slide plate 31. A movable plate 32 is provided between the slide plates 31. A movable roller 33 is provided at the bottom of the movable plate 32. The movable plate 32 is fixedly connected to the movable block 29, which enables the fourth driving member 28 to drive the movable plate 32 to move axially back and forth. A transmission belt 34 is sleeved around the movable plate, the fixed plate 25, the movable roller 33, and the fixed roller 24. The fourth driving member 28 drives the movable shaft 27 to rotate, thereby driving the movable block 29 to move. The sliding connection between the slide rail 30 and the slide plate 31, and the fixed connection between the movable plate 32 and the movable block 29, ensure that the movable plate 32 can move axially back and forth along the slide rail 30. Under normal conditions, the movable plate 32 is in an extended state and abuts against the lower clamping plate 8 on one side, while the lower clamping plate 8 on the other side is placed below the movable plate 32.When one end of the material is transported to the lower clamping plate 8 for clamping, a sensor is also provided on the moving plate 32 to detect the end of the material. When the sensor detects the end of the material, the moving plate 32 begins to retract, retracting to the side of the clamping plate originally located below the moving plate 32. The clamping plate then clamps the material to fix both ends. The clamping plates at both ends then move up and down and rotate for processing. The frame 1 is provided with a truss 35 and a worktable 36. The connecting mechanism 3 includes a lifting cylinder 37 passing through the truss 35. An upper mold machine 38 is fixedly installed at the end of the lifting cylinder 37. A lower mold machine 39 is fixedly installed on the top of the worktable 36. The frame 1 is located below the worktable 36 and has a moving plate 32 for fixing. After the plate 25 retracts, the storage cavity 40 for storing materials is connected to the truss 35. The lifting cylinder 37 drives the upper mold machine 38, which cooperates with the lower mold machine 39 fixed on the top of the worktable 36. The side clamps are raised and lowered to the horizontal position of the lower mold machine 39 to realize the connection and processing of materials. When the moving plate 32 retracts towards the fixed plate 25, the material can be stored in the storage cavity 40, which enables the equipment to process long materials and avoids the edges from peeling during processing due to the material being too long, thus ensuring the quality and stability of processing. The top of the conveyor plate 23 is provided with several fixed frames 41, and the fixed frames 41 are provided with connecting shafts 42. The other end of the connecting shafts 42 is provided with connecting parts 43, connecting... A guide plate 44 is provided at the other end of the plate 18. The guide plate 44 is placed on the surface of the transmission belt 34. The conveying plate 23 is provided with a pressure roller 47 seat 45 at the position of the moving plate 32. A pressure roller shaft 46 is rotatably connected between the pressure roller 47 seats 45. Several pressure rollers 47 are sleeved on the pressure roller shaft 46. The fixed frame 41 provided on the top of the conveying plate 23, as well as the connecting shaft 42, connecting piece 43 and guide plate 44 passing through it, can play a precise guiding role for the material on the transmission belt 34. The pressure rollers 47 can apply appropriate pressure to the material on the transmission belt 34 to ensure sufficient friction between the material and the transmission belt 34. At the same time, after the moving plate 32 retracts, the pressure rollers 47 can press the end of the material. The edges ensure that materials will not fall due to their own weight, enhancing the stability of the clamping plates. A toothing machine 48 is located on one side of the frame 1 at the fixed conveyor end 6, and a winding machine 49 is located on the other side of the toothing machine 48. An opening 50 for material passage is provided on the side of the frame 1 facing the winding machine 49. The toothing machine 48 on the side of the frame 1 facing the fixed conveyor end 6 ensures that the material undergoes toothing processing before connection, achieving a close connection between the feeding and toothing processes. The opening 50 on the side of the frame 1 facing the winding machine 49 allows the material to smoothly enter the toothing machine 48 for toothing processing, and then be transferred from the winding machine 49 to the fixed conveyor end 6 for connection processing.
