Description

Technical Field

[0001] This utility model relates to the field of shearing machines, specifically a belt shearing machine. Background Technology

[0002] Currently, belts are a crucial component of transmission systems. In conventional belt production, workers manually pull the belt from the drum onto a worktable. The worktable has a reference point and a central folding pulley. The worker holds the belt's end and walks along the worktable from one side of the reference point until the belt is wrapped around the central folding pulley. Then, the worker pulls the belt back until the end aligns with the reference point, indicating the required length has been reached. The belt is then cut at the designated location, completing the belt shearing. However, manual production is prone to belt tension issues, leading to errors in the shearing length and increased scrap rates. Furthermore, manual shearing can only produce one belt length; when different sizes are needed, the reference point or central folding pulley must be readjusted, resulting in low production efficiency. Therefore, the applicant proposes a belt shearing machine solution suitable for automated belt production, thereby improving production efficiency. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] refer to Figures 1 to 6 As shown, a belt shearing machine includes a frame 1 with a worktable 101. The frame 1 has a feeding mechanism 2 for feeding a belt A onto the worktable 101 and a clamping mechanism 3 for clamping the head end of the belt A on the discharge side of the worktable 101. The worktable 101 also has a pulling mechanism 4 for folding the belt A back and pulling it away from the discharge side. Furthermore, the frame 1 has a cutting mechanism 5 for cutting the belt A to a measured length. The cutting mechanism 5 is arranged in front of the feeding mechanism 2 along the feeding direction. A cutting fixing mechanism 6 is provided between the feeding mechanism 2 and the cutting mechanism 5 to clamp the belt A before cutting it. A step reading mechanism 7 is provided behind the feeding mechanism 2 to measure the length of the belt A.

[0023] This belt shearing machine can automatically feed, stretch, measure, and cut belt A, improving the automation level of belt A shearing. It can also quickly adapt to produce belts of different sizes, increasing the production efficiency of belt A shearing. The belt measurement is accurate with little error, significantly reducing the scrap rate. In addition, belt A is measured by folding back, which can reduce the length of the worktable by half, which is conducive to the miniaturization of the belt shearing machine and saves factory space resources.

[0024] The frame 1 is also provided with a measuring reference plate 8 for limiting the head end of the belt A, and the measuring reference plate 8 is located on the rear side of the clamping mechanism 3.

[0025] The feeding mechanism 2 includes a feeding fixed seat 21, a sliding seat 22 is slidably connected to the feeding fixed seat 21, a movable pressing wheel 23 and a servo motor 24 for driving the movable pressing wheel 23 to rotate are connected to the sliding seat 22, and a fixed pressing wheel 26 opposite to the movable pressing wheel 23 is provided on the other side of the feeding fixed seat 21. In addition, a pressure spring 25 is provided between one side of the sliding seat 22 and the feeding fixed seat 21. The movable pressure wheel 23 and the fixed pressure wheel 26 can be elastically clamped by the pressure spring 25, so that when the belt is pulled outward, the belt A can be tightened to prevent the belt A from becoming loose. An adjusting screw 27 is also provided on one side of the sliding seat 22. The adjusting screw 27 abuts against one end of the pressure spring 25. Adjusting the position of the adjusting screw 27 changes the pressure between the movable pressure roller 23 and the fixed pressure roller 26, so as to avoid the movable pressure roller 23 and the fixed pressure roller 26 being clamped too tightly or too loosely, resulting in unsatisfactory tensioning efficiency.

[0026] The clamping mechanism 3 includes a clamping base plate 31, on which a fixed clamping plate 32, a movable clamping block 33, and a clamping cylinder 34 are provided to drive the movable clamping block 33 to move back and forth relative to the fixed clamping plate 32. A clamping opening 301 is formed between the fixed clamping plate 32 and the movable clamping block 33.

[0027] The material pulling mechanism 4 includes a material pulling motion device mounted on the frame 1 and a pulling wheel 41 mounted on the worktable 101. The moving end of the material pulling motion device is provided with a wheel axle 42 extending out of the worktable 101. The pulling wheel 41 is rotatably connected to the wheel axle 42, and the wheel surface of the pulling wheel 41 is provided with a limiting wheel groove 411 for limiting the belt A. The limiting wheel groove 411 can prevent the belt from detaching from the pulling wheel 41 during the pulling process.

[0028] The material pulling device includes a linear slide rail 43 arranged along the length of the worktable 101. The two ends of the linear slide rail 43 are respectively connected to a drive wheel 44 and a driven wheel 45. A transmission belt 46 is connected between the drive wheel 44 and the driven wheel 45. A material pulling motor 47 for driving the drive wheel 44 to rotate is provided on the linear slide rail 43. A slider seat 48 is slidably connected to the linear slide rail 43. The slider seat 48 is fixedly connected to the transmission belt 46. The wheel axle 42 is fixed on the slider seat 48.

[0029] The cutting mechanism 5 includes a cutting base plate 51, on which a support frame 52 and a guide seat 53 are provided. A stamping cylinder 54 is provided on the support frame 52, and a cutter 55 is connected to the piston shaft of the stamping cylinder 54. A feeding guide rail 56 passes through the guide seat 53, and a straight feeding channel 562 is defined within the feeding guide rail 56. A slit 531 is provided on the guide seat 53 at the position corresponding to the lower cutter position to block the straight feeding channel 562.

[0030] The cutting and fixing mechanism 6 includes a supporting vertical plate 61, which can form a measuring reference plate 8 for limiting the head end of the belt A. A fixing cylinder 62 is horizontally connected to the supporting vertical plate 61. A pressing block 63 is provided on the piston shaft of the fixing cylinder 62. A pressing inlet 561 corresponding to the pressing block 63 is provided on the feeding guide rail 56, which connects to the linear material guiding channel 562. The pressing block 63 passes through the pressing inlet 561 and presses against the belt A. Before the cutter 55 cuts the belt, the pressing block 63 presses the belt tightly to prevent the belt from pulling back after cutting, and also allows the belt to continue to be conveyed in the linear material guiding channel 562.

[0031] The step reading mechanism 7 includes a straightening fixing base 71, on which a fixed feeding wheel 72 and a movable feeding wheel 73 that moves back and forth relative to the fixed feeding wheel 72 are provided. A step reader 74 is connected to the bottom surface of the straightening fixing base 71, and the fixed feeding wheel 72 is fixedly connected to the drive shaft of the step reader 74. In addition, multiple sets of straightening wheels 75 are provided on the straightening fixing base 71 behind the fixed feeding wheel 72 and the movable feeding wheel 73. The belt is straightened by the multiple sets of straightening wheels 75 and then fed into the feeding mechanism 2.

[0032] Based on the above structure, the working principle of the belt shearing machine is as follows: 1. During initial operation, the belt on the belt drum is fed into the step reading mechanism 7 and the feeding mechanism 2. The belt is elastically clamped between the movable pressure wheel 23 and the fixed pressure wheel 26. The servo motor 24 drives the movable pressure wheel 23 to rotate, so that the belt is fed into the linear guide channel until the belt passes through the slit 531. Then, the stamping cylinder 54 drives the cutter 55 to cut into the slit 531 and cut the belt. The step reader 74 determines that the length is zero.

[0033] 2. During the actual shearing, the worker pulls the head end of belt A onto the workbench 101. During the pulling process, the step reader 74 will follow and record the length. Afterward, belt A is passed around the pulling wheel 41 and through the clamping port 301, so that the head end of belt A is pressed against the measuring reference plate 8. Then, the clamping cylinder 34 drives the clamping block 33 to move relative to the fixed clamping plate 32, thereby clamping the head end of belt A.

[0034] 3. When the material pulling motor 47 is working, the transmission belt 46 rotates between the driving wheel 44 and the driven wheel 45. At the same time, the transmission belt 46 drives the slider seat 48, the wheel axle 42 and the pulling wheel 41 to move away from the discharge side, thereby pulling the longer belt onto the worktable 101.

[0035] 4. When the step reader 74 measures the length of the belt pulled out by the fixed feeding wheel 72, the pulling motor 47 stops working, and then the fixed cylinder 62 works to drive the pressing block 63 to extend from the pressing inlet 561 into the linear guide channel and press the belt.

[0036] 5. The stamping cylinder 54 works again, driving the cutter 55 to cut into the slit 531 and cut the belt. Finally, the clamping mechanism 3 releases the head end of the belt, thus completing the shearing process of one belt. Then, the above steps 2-5 are repeated.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
