[0018] This utility model provides, for example Figures 1 to 4 The adjustable edge-cutting device for rubber belt production shown includes a worktable 1, which is a U-shaped table. Both ends of the worktable 1 are fixed seats, and a guide rod 8 is horizontally placed between the two fixed seats, with the guide rod 8 fixedly connected to the two fixed seats.

[0019] Two sliding seats 7 are provided between the two far ends of the worktable 1. The guide rod 8 is a square rod that passes through the two sliding seats 7, and both sliding seats 7 are in a limiting sliding engagement with the guide rod 8.

[0020] A tensioning element for tensioning the rubber belt is installed on the top of each of the two sliding seats 7.

[0021] Specifically, the tensioning element includes a horizontal tensioning roller 10 arranged along the width of the rubber belt. A first motor 9 is fixedly mounted on the sliding seat 7, and the tensioning roller 10 is coaxially connected to the output shaft of the first motor 9.

[0022] A support plate, which is an inverted L-shaped plate, is fixedly installed on the workbench 1. Two electrically synchronized push rods 2 are fixedly installed on the top of the support plate. The telescopic shafts of the two electric push rods 2 are vertically downward and fixedly connected to the same horizontal movable plate 3.

[0023] A cutting mechanism is installed on the movable plate 3. The cutting mechanism is used to cut the edge of the rubber belt.

[0024] Specifically, the cutting mechanism includes two blade holders 17. A downward-facing groove is formed at the bottom of the movable plate 3 along the width of the rubber belt. A bidirectional threaded rod 15 is horizontally placed within the groove along the width of the rubber belt, and the bidirectional threaded rod 15 is rotatably connected to the movable plate 3. A second motor 16 is fixedly mounted on the movable plate 3, and the output shaft of the second motor 16 rotatably passes into the groove and is coaxially fixedly connected to the bidirectional threaded rod 15.

[0025] Two tool holders 17 are slidably installed into the groove, and a bidirectional threaded rod 15 passes through the two tool holders 17. The two tool holders 17 correspond one-to-one with the two threaded segments of the bidirectional threaded rod 15, and each tool holder 17 is threadedly connected to the corresponding threaded segment.

[0026] Each blade holder 17 has a blade 18 fixedly mounted at its bottom for cutting the rubber strip, with the rubber strip located between the two blades 18.

[0027] A transmission assembly is provided between the movable plate 3 and the two sliding seats 7. The transmission assembly is used to drive the two sliding seats 7 to slide closer to or further away from the guide rod 8.

[0028] Specifically, the transmission assembly includes two spring telescopic rods 6. Two first hinge seats 4 are fixedly mounted on the movable plate 3, and one second hinge seat 5 is fixedly mounted on each of the two sliding seats 7. The two first hinge seats 4 and the two second hinge seats 5 correspond one-to-one, and a spring telescopic rod 6 is hinged between each first hinge seat 4 and the corresponding second hinge seat 5.

[0029] A mounting frame 11 is fixedly installed on the workbench 1. A vertically mounted fixing rod 12 is fixed on the mounting frame 11. A fixing block 13 is fixedly installed on the fixing rod 12. A horizontally mounted support roller 14, which is arranged along the width direction of the rubber belt, is rotatably installed on the fixing block 13. The support roller 14 and two tensioning members are arranged in a triangular array in the vertical plane.

[0030] The rubber belt is sleeved on the support roller 14 and the two tension rollers 10, and the support roller 14 and the two tension rollers 10 roll and abut against the rubber belt.

[0031] It should be noted that, in order to accommodate more sizes or models of rubber belts, the fixing block 13 can be slidably installed on the fixing rod 12. The fixing block 13 is threaded with a fastening bolt, which is used to abut and limit the fixing rod 12, thereby facilitating adjustment and improving the adaptation range. This is existing technology and will not be described in detail here.

[0032] Working principle: First, the rubber belt to be cut is placed on the support roller 14 and the two tension rollers 10. The triangular array arrangement of the support roller 14 and the two tension rollers 10 in the vertical plane is used to achieve the initial support and positioning of the rubber belt. The support roller 14 and the two tension rollers 10 are in rolling contact with the rubber belt, which lays the foundation for subsequent smooth conveying and cutting.

[0033] Then, the electric push rod 2 on the support plate is activated. The telescopic shaft of the electric push rod 2 extends downward, driving the movable plate 3, which is fixedly connected to it, to move downward in the vertical direction. When the movable plate 3 moves downward, the two first hinge seats 4 at its bottom move downward synchronously. Through the hinged spring telescopic rod 6, the second hinge seat 5 on the corresponding sliding seat 7 is pulled, causing the two sliding seats 7 to slide along the guide rod 8 of the polygonal structure and move away from each other. As the distance between the two sliding seats 7 increases, the tensioning rollers 10 installed on the sliding seats 7 separate synchronously, thereby gradually tensioning the sleeved rubber belt until the required tension for trimming is reached. The spring telescopic rod 6 can buffer the force during the tensioning process to prevent the rubber belt from being damaged due to excessive tension. This process does not require a separate tensioning power source. Through the linkage between the downward movement of the movable plate 3 and the transmission component, the trimming mechanism approaches and the rubber belt is tensioned synchronously, simplifying the structure and reducing energy consumption.

[0034] Next, according to the design width requirements of the rubber belt, the second motor 16 on the movable plate 3 is started. The output shaft of the second motor 16 drives the bidirectional threaded rod 15, which is coaxially fixed to it, to rotate in the slide groove of the movable plate 3. Since the two cutter holders 17 are respectively threadedly connected to the two threaded sections of the bidirectional threaded rod 15, and the cutter holders 17 are limited and slidingly engaged with the slide groove, the rotation of the bidirectional threaded rod 15 will drive the two cutter holders 17 to slide in opposite directions along the slide groove, thereby adjusting the distance between the bottom blades 18 of the two cutter holders 17 so that the distance is consistent with the target cutting edge size of the rubber belt, ensuring that a precise trapezoidal cross section is formed after cutting, and avoiding damage to the internal reinforcing cord of the rubber belt.

[0035] After the tension and cutting edge spacing are adjusted, the first motors 9 on the two sliding seats 7 are started. The two first motors 9 are electrically synchronized, and the output shaft of the first motor 9 drives the tension roller 10, which is coaxially fixed to it, to rotate. Since the tension roller 10 is parallel to the support roller 14 and the rubber belt is in a taut state, the rotation of the tension roller 10 will drive the rubber belt to be conveyed at a constant speed along the rolling contact surface between the support roller 14 and the tension roller 10. During this process, the movable plate 3 maintains its current height, so that the two blades 18 are always close to the excess rubber on both sides of the rubber belt. As the rubber belt continues to be conveyed at a constant speed, the two blades 18 simultaneously perform double-sided precision cutting of the rubber belt, removing the excess rubber on the sides, and finally forming a smooth and precise trapezoidal cross-section product.

[0036] After the rubber belt has been fully conveyed, the edge trimming process is completed. The first motor 9 and the second motor 16 are turned off, and the telescopic shaft of the electric push rod 2 is retracted, causing the movable plate 3 to return to its original position. As the movable plate 3 moves upward, the spring telescopic rod 6 pushes the two sliding seats 7 closer together along the guide rod 8, and the tension rollers 10 move in sync, releasing the tension of the rubber belt. The trimmed rubber belt can then be removed, completing a single edge trimming operation.

[0037] It should be noted that the workbench 1 is fixedly equipped with a controller that controls the start, stop and shut down of all electric components, and also has a corresponding control circuit, which is existing technology and will not be described in detail in this embodiment.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
