Description
Technical Field
[0001] This utility model relates to the technical field of conveyor belt stripping devices, and in particular to a conveyor belt joint stripping machine. Background Technology
[0002] Conveyor belts mainly consist of an inner core layer and an outer skin layer. The outer skin layer is primarily made of materials such as rubber or plastic, while the inner core layer is mainly composed of nylon or polyester core fibers. When a conveyor belt tears or shows signs of wear, and the ends at the tear or wear area need to be reconnected, whether hot or cold bonding is used, the ends at the tear or wear area must be peeled off. Traditional peeling methods are mainly done manually. However, the inner core layer has good adhesion to rubber and plastic, which makes manual peeling of the belt ends extremely difficult. It usually requires at least 4 to 6 people to complete, and the process can take 4 to 6 hours. This is not only time-consuming but also extremely physically demanding for workers, easily leading to back injuries or falls, posing a certain safety hazard.
[0003] To reduce labor intensity and improve safety and efficiency, mechanical conveyor belt splice stripping machines have emerged on the market. However, in practical applications, these machines typically require specialized fixing devices to secure both the stripper and the conveyor belt to a reliable and robust base. This prevents equipment movement during the stripping process from affecting the stripping effect, limiting their use to repair shops with fixed devices and bases. This restricts their application to on-site belt stripping and repair, limiting their applicability. Therefore, a conveyor belt splice stripping machine with wider application scenarios is urgently needed. Utility Model Content
[0004] The purpose of this utility model is to solve the above-mentioned technical problems and provide a conveyor belt splice peeling machine. Since the winding device and the pressing mechanism are both set on the peeling platform, the tensile force on the conveyor belt and the winding device is the internal force of the conveyor belt splice peeling machine. Because there is no external force, the conveyor belt splice peeling machine will not move during the peeling process. Therefore, there is no need for additional fixing devices to fix the conveyor belt and the conveyor belt splice peeling machine. This makes the conveyor belt splice peeling machine usable not only in repair shops, but also at the conveyor belt application site or any open scene, effectively expanding the scope of application.
[0005] To achieve the above objectives, this utility model provides the following solution: This utility model discloses a conveyor belt splice peeling machine, including a peeling platform, a clamp, a traction rope, and a winding device for winding the traction rope. The winding device is installed on the peeling platform, and the peeling platform has a placement area adjacent to the winding device. The placement area is used to place the end of the conveyor belt to be repaired. The end to be repaired is divided into a peeling section and a pressing section along the length direction of the conveyor belt. The peeling section faces the winding device. One end of the peeling section adjacent to the pressing section has a skin layer clamping end. The clamp is used to clamp the skin layer clamping end. The traction rope is connected to the clamp. The peeling platform has a pressing mechanism for pressing the pressing section into the placement area.
[0006] In one embodiment, the peeling platform includes a rectangular support plate and a movable guide rail. The placement area is disposed on the rectangular support plate.

The extension direction of the movable guide rail is parallel to the width direction of the rectangular support plate. The winding device is movable along the movable guide rail.
[0007] In one embodiment, the winding device moves along the moving guide rail via traveling wheels.
[0008] In one embodiment, the winding device includes a winding wheel and a drive mechanism for driving the winding wheel to rotate, one end of the traction rope is fixed and wound around the winding wheel, and the other end of the traction rope is fixedly connected to the clamp.
[0009] In one embodiment, there is a preset vertical distance between the central axis of the take-up reel and the peeling section, and a preset horizontal distance between the central axis of the take-up reel and the end of the peeling section adjacent to the pressing section, wherein the preset vertical distance is less than the preset horizontal distance.
[0010] In one embodiment, the drive mechanism includes a reducer and a drive motor. The reducer is movably mounted on the moving guide rail. The housing of the drive motor is fixedly connected to the housing of the reducer. The motor shaft of the drive motor is coaxially fixedly connected to the input shaft of the reducer.
[0011] In one embodiment, a control box is mounted on the moving guide rail, and the control box is electrically connected to the drive motor.
[0012] In one embodiment, the control box is provided with a control handle, and the control handle is provided with a control button.
[0013] In one embodiment, the pressing mechanism includes a pressure bar and a handwheel. The placement area is provided with threaded holes, which are distributed on both sides of the placement area along the width direction of the rectangular support plate. The pressure bar is provided with through holes corresponding to the threaded holes. A threaded rod is coaxially fixedly connected to the handwheel. The threaded rod is used to pass through the through hole and be threadedly connected to the threaded hole. The threaded rod is provided with a downward pressing protrusion located above the through hole. The outer diameter of the downward pressing protrusion is larger than the diameter of the through hole.
[0014] In one embodiment, the clamp is a self-locking clamp.
[0015] The present invention achieves the following technical advantages over the prior art:
[0016] In this utility model of a conveyor belt splice peeling machine, since both the winding device and the pressing mechanism are located on the peeling platform, the conveyor belt is pressed tightly onto the peeling platform. When peeling is performed using traction ropes and clamps, the tensile force on the conveyor belt and the tensile force on the winding device are both internal forces of the conveyor belt splice peeling machine. The conveyor belt splice peeling machine does not generate external forces. Therefore, the conveyor belt splice peeling machine will not move during the peeling process, and there is no need for additional fixing devices to fix the conveyor belt splice peeling machine and the conveyor belt. As a result, it can be used not only in repair shops, but also at the conveyor belt application site or any other open scene, effectively expanding the scope of application.

[0025] 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 analyzed and obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] The purpose of this invention is to provide a conveyor belt splice peeling machine to solve the problems existing in the prior art. Since the winding device and the pressing mechanism are both set on the peeling platform, when the conveyor belt is pressed on the peeling platform and peeled using the traction rope and clamps, the tensile force on the conveyor belt and the tensile force on the winding device are both internal forces of the conveyor belt splice peeling machine. Therefore, the conveyor belt splice peeling machine as a whole will not move, and there is no need for external force to fix the conveyor belt splice peeling machine. As a result, it can be used not only in repair shops, but also at the conveyor belt application site or any open scene, effectively expanding the scope of application.
[0027] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] like Figures 1 to 6As shown, this embodiment provides a conveyor belt splice peeling machine, including a peeling platform, a traction rope 6, a clamp 7, and a winding device. The winding device is installed on the peeling platform and is used to wind up the traction rope 6. The peeling platform has a placement area adjacent to the winding device, which is used to place the end of the conveyor belt to be repaired. The end of the conveyor belt to be repaired is divided into a peeling section and a pressing section along the length of the conveyor belt. The peeling section faces the winding device, and a skin layer clamping end 14 is provided at one end of the peeling section adjacent to the pressing section. The clamp 7 is used to clamp the skin layer clamping end 14, and the traction rope 6 is connected to the clamp 7. A pressing mechanism is provided on the peeling platform to press the pressing section into the placement area. When the winding device winds up the traction rope 6, the clamp 7 can pull the skin layer clamping end 14, tearing it away from the pressing section of the peeling section, until the skin layer 13 where the skin layer clamping end 14 is located is peeled off from the inner core layer 12. Since the winding device and the clamping mechanism are both located on the stripping platform, the tensile force on the conveyor belt and the tensile force on the winding device are both internal forces of the conveyor belt splice stripper. Therefore, when stripping the outer layer 13, the conveyor belt splice stripper will not move as a whole, and there is no need for external force to fix the conveyor belt splice stripper. As a result, it can be used not only in repair shops, but also at the application site or in any open environment, effectively expanding the scope of application.
[0029] Workflow:
[0030] First, place the end of the conveyor belt to be repaired on the placement area, with the peeling section (length should not exceed 1000mm, 300mm is optimal to allow for gaps in later vulcanization repair) facing the winding device. Use the clamping mechanism to press the clamping section of the conveyor belt to be repaired. Then, using a tool, peel off a portion of the raised corner from the skin layer 13 (rubber or plastic vulcanized layer) at one end of the peeling section adjacent to the clamping section to form a skin layer clamping end 14 (the length of the skin layer clamping end 14 is usually 20mm). The width of the skin layer clamping end 14 peeled off each time should not be too large. Several skin layer clamping ends 14 are sequentially peeled off along the width of the conveyor belt. This allows the entire skin layer 13 on the peeling section to be torn off in strips, resulting in less resistance compared to tearing the entire sheet at once. Then, the clamping ends 14 are held in place by the clamp 7, and the winding device is activated. The winding device winds up the traction rope 6, which pulls the clamp 7, tearing the skin layer clamping ends 14 until a whole strip is detached from the inner core layer 12. The above steps are repeated to tear off the next strip until the entire skin layer 13 of the peeling section is peeled off, allowing subsequent repair processes to proceed. Preferably, the winding device winds up the traction rope 6 at a uniform speed.
[0031] In one embodiment, the peeling platform includes a rectangular support plate 2 and a moving guide rail 1, with a placement area disposed on the rectangular support plate 2. The moving guide rail 1 is fixedly connected to one of the length ends of the rectangular support plate 2. The extension direction of the moving guide rail 1 is parallel to the width direction of the rectangular support plate 2. A clamping mechanism is disposed on the other length end of the rectangular support plate 2. A winding device can move along the moving guide rail 1. In use, the end of the conveyor belt to be repaired is placed on the placement area, with the length direction of the conveyor belt as parallel as possible to the length direction of the rectangular support plate 2. This allows the winding device to move along the width direction of the conveyor belt as it moves along the moving guide rail 1. Based on the position of the peeled skin layer clamping end 14 on the conveyor belt in the width direction of the conveyor belt, the winding device can be moved so that the traction rope 6 of the winding device corresponds to the position of the skin layer clamping end 14. Maintaining the length direction of the traction rope 6 perpendicular to the width direction of the conveyor belt as much as possible facilitates pulling the skin layer clamping end 14, applying tension, and ensuring smooth tearing. Furthermore, during the winding process, as the winding device winds up the traction rope 6 and the traction rope 6 pulls the outer skin clamping end 14, the pulling force also acts on the winding device. Therefore, during the pulling process, when the pulling angle fluctuates slightly, the winding device will move along the moving guide rail 1, passively adjusting the force angle according to the change in the peeling angle. In addition, the length direction of the conveyor belt does not necessarily have to be parallel to the length direction of the rectangular support plate 2; it can also be used at a slight angle.
[0032] In one embodiment, the winding device moves along the movable guide rail 1 via a slider, that is, the slider is slidably connected to the movable guide rail.
[0033] In one embodiment, the winding device moves along the moving guide rail 1 via a traveling wheel. Compared to a slider, the traveling wheel rolls along the moving guide rail 1, resulting in less resistance and making it easier to move the winding device.
[0034] In one embodiment, the winding device includes a winding reel 5 and a drive mechanism. The drive mechanism drives the winding reel 5 to rotate. One end of the traction rope 6 is fixed and wound around the winding reel 5, and the other end of the traction rope 6 is fixedly connected to the clamp 7. By rotating the winding reel 5, the traction rope 6 can be wound up, pulling the clamp 7.
[0035] In one embodiment, the central axis of the winding wheel 5 has a preset vertical distance from the stripping section. The central axis of the winding wheel 5 has a preset horizontal distance from one end of the stripping section adjacent to the pressing section. The preset vertical distance is less than the preset horizontal distance, so that the vertical angle α between the traction rope 6 and the placement area of the rectangular support plate 2 is always less than 45°, and the force application angle is conducive to stripping.
[0036] In one embodiment, the drive mechanism includes a drive motor 3 and a reducer 4. The reducer 4 is movably mounted on the moving guide rail 1, meaning it can move along the guide rail 1, specifically via a slider or a traveling wheel. The housing of the drive motor 3 is fixedly connected to the housing of the reducer 4. The motor shaft of the drive motor 3 is coaxially fixedly connected to the input shaft of the reducer 4, and the output shaft of the reducer 4 is coaxially fixedly connected to the winding reel 5, allowing the drive motor 3 and the winding reel 5 to move with the reducer 4. When the motor shaft of the drive motor 3 rotates forward or backward, it drives the input shaft of the reducer 4 to rotate forward or backward, which in turn drives the winding reel 5 to rotate forward or backward via the output shaft of the reducer 4, thus achieving the winding and unwinding of the traction rope 6.
[0037] In one embodiment, a control box 8 is mounted on the movable guide rail 1. The control box 8 is electrically connected to the drive motor 3 and has control buttons. The control box 8 controls the start, forward and reverse rotation, and speed settings of the drive motor 3.
[0038] In one embodiment, the control box 8 is provided with a control handle 9, and the control handle 9 is provided with control buttons for controlling the start, forward rotation, reverse rotation and speed gear of the drive motor 3.
[0039] In one embodiment, the clamping mechanism includes a clamping bar 10 and a handwheel 11. Threaded holes are provided on the placement area, distributed on both sides of the placement area along the width direction of the rectangular support plate 2. A through hole is provided on the clamping bar 10, corresponding to the threaded hole. A threaded rod is coaxially fixedly connected to the handwheel 11, passing through the through hole and threadedly connected to the threaded hole. The threaded rod has a downward pressing protrusion located above the through hole, the outer diameter of which is larger than the diameter of the through hole. When the handwheel 11 is rotated to loosen the threaded rod, the downward pressing protrusion moves upward. At this time, the clamping bar 10 is lifted by hand, creating a gap between the clamping bar 10 and the rectangular support plate 2 for the conveyor belt to pass through. Then, the threaded rod is tightened, causing the downward pressing protrusion to move downward, pressing the clamping bar 10 against the clamping section of the conveyor belt, thus fixing the conveyor belt. Alternatively, you can unscrew the handwheel 11 and the threaded rod, remove the pressure bar 10, place the conveyor belt directly onto the rectangular support plate 2, and then reinstall the pressure bar 10 and the handwheel 11 to tighten the conveyor belt.
[0040] In one embodiment, the clamp 7 is a self-locking clamp.
[0041] In one embodiment, the rectangular support plate 2 has a length of approximately 1800 mm and a width of approximately 1363 mm, making it suitable for conveyor belts with a width of 1000 mm or less. Of course, these parameters can be adjusted as needed and do not mean that only these parameters can be used.
[0042] In one embodiment, this conveyor belt splice stripping machine mainly consists of a moving guide rail 1, a rectangular support plate 2, a drive motor 3, a reducer 4, a winding wheel 5, a traction rope 6, clamps (fixtures 7), a control box 8, a control handle 9, a pressure bar 10, a handwheel 11, and more than a dozen other components. The small number of components meets production needs while being safe, economical, easy to operate, and suitable for any location. The equipment has a compact structure, and all components work well together. From the fixed conveyor belt to the stripping action, the entire process is smooth, greatly improving work efficiency. According to actual usage statistics, usually only two employees are needed to complete the stripping, one operating and one supervising. The completion time, based on statistics from multiple stripping operations, is between 20 and 30 minutes. It requires less physical exertion and poses fewer safety hazards. In contrast, traditional manual methods require 4 to 6 hours, resulting in a significant efficiency improvement.
[0043] In one embodiment, the rectangular support plate 2 can be made of scrap compressed plate, and the handwheel 11 can be composed of scrap valve handwheel, screw, and nut. The scrap valve handwheel is welded to the screw, and the nut is welded to the screw as a downward pressing protrusion. The moving guide rail 1 can be made of two channel steels with the grooves of the two channel steels facing each other. The two channel steels are fixedly connected by a connecting plate. The traveling wheel includes two bearings, which are clamped on the upper and lower sides of the upper flange of the channel steel. The bearings are double-end face sealed deep groove ball bearings. The channel steel can be [5# channel steel]. Its design allows the equipment to be directly applied to the belt itself without removing the entire belt, simplifying the maintenance process. When repairing a faulty or damaged belt, the equipment can be directly installed on the belt for repair, with minimal impact on the overall equipment. It is especially effective for repairing small-scale early wear of the belt and repairing single defects at fixed points. The drive motor 3 can be a 0.75kw four-pole motor, and the reducer 4 is a reducer with a speed ratio of 121:1, such as a disc reducer. The winding reel 5 is a concave traction winding reel with a diameter of 100mm. The traction rope 6 is made of 6mm diameter steel wire rope. The clamps are heavy-duty clamps, characterized by their locking jaws and high clamping force to prevent the clamped parts from loosening. The jaws also have multiple adjustable positions for clamping parts of different thicknesses and can be used as a wrench. The clamping bar 10 is made of U-shaped steel bar with two through holes on its web, fitted with two handwheels 11. The U-shaped steel bar is used with the opening facing downwards. The control box 8 of the drive motor 3 uses a double-interlocked control circuit box for forward and reverse inching, effectively preventing phase-to-phase short circuits during the forward and reverse switching of the drive motor 3. The control handle 9 is an aviation plug-type double handle used to start and stop the drive motor 3 during belt stripping. The aforementioned components are mostly common market items, easy to procure, and inexpensive. They are safe, economical, easy to operate, and suitable for any location. Furthermore, the equipment has a compact structure, with all components working well together. From the fixed conveyor belt to the stripping action, the entire process is smooth, greatly improving work efficiency. A detailed cost comparison table is shown below:
[0044]
[0045] Calculation method: Labor: Average hourly wage per person * Time * Number of people;
[0046] Output: Hourly output / ton * time * price / ton.
[0047] This conveyor belt splice stripper is simple in structure and easy to install. It can be directly installed on the faulty belt. For small-scale repairs of initial belt wear and single-point defect repairs, it does not require complicated equipment adjustments or large-scale belt disassembly and installation. It can quickly locate and repair the problem area, reduce the impact on the overall operation of the conveyor belt, improve the overall operational stability and reliability of the equipment, and reduce maintenance and time costs.
[0048] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
