Description

Technical Field

[0001] This utility model relates to the field of edge trimming machine technology, specifically to a winding tension control device for an edge trimming machine. Background Technology

[0002] An edge trimming machine is a device used to cut and trim the edges of materials. Its main function is to cut and trim the edges of materials such as boards and paper to make them more beautiful and smooth. Edge trimming machines cut and trim materials by rotating saw blades or plywood blades, and can perform a variety of operations, such as angle cutting, chamfering and beveling, thereby improving processing efficiency and work quality.

[0003] Currently, before the existing take-up rollers can take up the fiberglass cloth, the paper core needs to be fixed to the side wall of the take-up roller. The working principle is: insert the paper core into the side wall of the take-up roller, drive the take-up roller to rotate at high speed, so that the cam mechanism inside the take-up roller drives the slider to push out, and the rubber pad on the side wall of the slider presses against the inner wall of the paper core, thereby fixing the paper core to the side wall of the take-up roller.

[0004] In the above-mentioned solution, the existing technology uses the force generated during rotation to push the slider out and fix the paper core. However, there is sometimes not enough friction between the slider and the paper core, which makes it easy for the paper core to slip, thus failing to guarantee the winding quality. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a winding tension control device for an edge trimming machine. By providing a fixing mechanism, the paper core can be fixed in the required position, solving the problem of paper core slippage in the prior art and ensuring that the winding quality is not affected.

[0006] The solution of this utility model to the aforementioned technical problem is:

[0007] A winding tension control device for an edge trimming machine includes a first frame and a second frame. Multiple conveying rollers are rotatably connected to the upper ends of the first frame and the second frame. An adjustable tension roller is provided inside the first frame. Two rotating wheels are symmetrically rotatably connected to the upper end of the second frame. A detachable winding roller is provided between the two rotating wheels. A fixing mechanism is provided inside the winding roller. A drive assembly is provided on one side of the second frame.

[0008] When the fiberglass cloth needs to be wound up, the winding roller is removed, and then the paper core is inserted into the side wall of the winding roller. The winding roller is then installed between the two rotating wheels. After adjusting the position of the paper core, the fixing mechanism is activated to fix the paper core in the required position. Then, the extended end of the fiberglass cloth, after passing through multiple conveying rollers and tension rollers, is wrapped around the side wall of the paper core. The drive assembly is then activated to drive the winding roller to rotate. The rotation of the winding roller drives the paper core to rotate, thereby winding up the fiberglass cloth. At the same time, the tension roller, which is equipped with adjustable tension, allows the tension of the fiberglass cloth to be adjusted as needed during winding.

[0009] By incorporating a fixing mechanism, the paper core can be fixed in the required position, solving the problem of paper core slippage in existing technologies and ensuring that the winding quality is not affected.

[0010] The utility model is further configured such that: the tension roller with adjustable tension includes two sliding plates symmetrically fixed at the bottom of the first frame, each end of the tension roller is rotatably connected to a pulley slidably connected in the sliding plate, a moving block is rotatably connected to the side wall of one of the pulleys, and a cylinder is fixed on the side wall of the first frame, with the output end of the cylinder fixed at the upper end of the moving block.

[0011] With the above technical solution, when it is necessary to adjust the tension of the fiberglass cloth during winding, the cylinder is activated to drive the moving block to move. The movement of the moving block drives the tension roller to move through the pulley, thereby adjusting the tension of the fiberglass cloth during winding as needed.

[0012] The utility model is further configured such that: the detachable take-up roller includes a slot fixed on the side wall of the rotating wheel, and each end of the take-up roller is fixed with a block that mates with the slot. A threaded rod that passes through the slot is fixed at the lower end of the block, and a nut is screwed onto the threaded rod.

[0013] With the above technical solution, when the take-up roller needs to be disassembled, the nut is turned and removed, so that the take-up roller can be removed. When the take-up roller needs to be installed, the locking block is inserted into the locking groove, and then the nut is screwed onto the threaded rod, and the nut is pressed against the bottom of the locking groove, so that the take-up roller can be fixed in the required position.

[0014] The utility model is further configured such that: the fixing mechanism includes a fixing component and a control component, the fixing component includes a plurality of clearance holes formed on the side wall of the take-up roller, a guide plate is fixed on each side of the clearance hole, and the same pressure plate is slidably connected between the two guide plates.

[0015] With the above technical solution, when it is necessary to fix the paper core, the control component is activated, which simultaneously drives multiple pressure plates to move outward and press the pressure plates against the inner wall of the paper core, thereby fixing the paper core.

[0016] The utility model is further configured such that: the control component includes a first motor fixed inside the take-up roller, a lead screw fixed to the output end of the first motor, a drive block screwed onto the lead screw, and multiple connecting rods rotatably connected to the side wall of the drive block, the multiple connecting rods being arranged in correspondence with multiple pressure plates, and the ends of the connecting rods being rotatably connected to the side wall of the pressure plates.

[0017] With the above technical solution, when it is necessary to move multiple pressure plates at the same time, the first motor is started, which drives the lead screw to rotate. The rotation of the lead screw drives the drive block to move. At the same time, under the action of multiple connecting rods, multiple pressure plates can be moved at the same time.

[0018] The utility model is further configured such that: the drive assembly includes a second motor fixed to the bottom of the second frame, a first pulley fixed to the output end of the second motor, a second pulley fixed to the protruding end of the rotating wheel passing through the second frame, and a belt installed between the first pulley and the second pulley.

[0019] With the above technical solution, when it is necessary to drive the take-up roller to rotate, the second motor is started, which drives the first pulley to rotate. The rotation of the first pulley drives the second pulley to rotate through the belt. The rotation of the second pulley drives the rotating wheel to rotate, thereby driving the take-up roller to rotate.

[0020] The utility model is further configured such that two sets of fixing mechanisms are symmetrically arranged.

[0021] The above technical solution improves the fixation effect on the paper core, ensuring that the paper core will not slip.

[0022] The beneficial effects of this utility model are:

[0023] Compared with existing technologies, this technology incorporates a fixing mechanism that secures the paper core in the desired position, solving the problem of paper core slippage that often occurs in existing technologies and ensuring that the winding quality is not affected.

[0024] The fixing mechanism is provided in two sets, which improves the fixing effect on the paper core. Attached Figure Description

[0031] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0032] The following is for reference Figures 1 to 5 This utility model will now be described.

[0033] A winding tension control device for an edge trimming machine includes a first frame 1 and a second frame 2. Multiple conveying rollers 3 are rotatably connected to the upper ends of the first frame 1 and the second frame 2. An adjustable tension roller 4 is provided inside the first frame 1. Two rotating wheels 5 are symmetrically rotatably connected to the upper end of the second frame 2. A detachable winding roller 6 is provided between the two rotating wheels 5. A fixing mechanism is provided inside the winding roller 6. A drive assembly is provided on one side of the second frame 2.

[0034] When the fiberglass cloth needs to be wound up, the winding roller 6 is removed, and then the paper core is inserted into the side wall of the winding roller 6. The winding roller 6 is then installed between the two rotating wheels 5. After adjusting the position of the paper core, the fixing mechanism is activated to fix the paper core in the required position. Then, the extended end of the fiberglass cloth after passing through multiple conveying rollers 3 and tension rollers 4 is wound around the side wall of the paper core. Then, the drive assembly is activated to drive the winding roller 6 to rotate. The rotation of the winding roller 6 drives the paper core to rotate, thereby winding up the fiberglass cloth. At the same time, the tension roller 4, which is equipped with adjustable tension, allows the tension of the fiberglass cloth to be adjusted as needed during winding.

[0035] By incorporating a fixing mechanism, the paper core can be fixed in the required position, solving the problem of paper core slippage in existing technologies and ensuring that the winding quality is not affected.

[0036] The adjustable tension roller 4 includes two sliding plates 7 symmetrically fixed at the bottom of the first frame 1. Each end of the tension roller 4 is rotatably connected to a pulley 8 that is slidably connected in the sliding plate 7. A moving block 9 is rotatably connected to the side wall of one of the pulleys 8. A cylinder 10 is fixed on the side wall of the first frame 1. The output end of the cylinder 10 is fixed to the upper end of the moving block 9.

[0037] When it is necessary to adjust the tension of the fiberglass cloth during winding, the cylinder 10 is activated, which drives the moving block 9 to move. The movement of the moving block 9 drives the tension roller 4 to move through the pulley 8, so that the tension of the fiberglass cloth during winding can be adjusted as needed.

[0038] The detachable take-up roller 6 includes a slot 11 fixed on the side wall of the rotating wheel 5. Each end of the take-up roller 6 is fixed with a locking block 12 that mates with the slot 11. The lower end of the locking block 12 is fixed with a threaded rod 13 that passes through the slot 11. A nut 14 is screwed onto the threaded rod 13.

[0039] When the take-up roller 6 needs to be disassembled, rotate the nut 14 to remove the nut 14, thereby removing the take-up roller 6. When the take-up roller 6 needs to be installed, insert the locking block 12 into the locking groove 11, and then screw the nut 14 onto the threaded rod 13, and press the nut 14 against the bottom of the locking groove 11, thereby fixing the take-up roller 6 in the required position.

[0040] The fixing mechanism includes a fixing component and a control component. The fixing component includes multiple clearance holes 601 formed on the side wall of the take-up roller 6. A guide plate 15 is fixed on each side of the clearance hole 601, and the same pressure plate 16 is slidably connected between the two guide plates 15.

[0041] When it is necessary to fix the paper core, the control component is activated, which simultaneously moves multiple pressure plates 16 outward and presses the pressure plates 16 against the inner wall of the paper core, thereby fixing the paper core.

[0042] The control assembly includes a first motor 17 fixed inside the take-up roller 6. A lead screw 18 is fixed to the output end of the first motor 17. A drive block 19 is screwed onto the lead screw 18. Multiple connecting rods 20 are rotatably connected to the side wall of the drive block 19. The multiple connecting rods 20 are arranged one-to-one with multiple pressure plates 16. The ends of the connecting rods 20 are rotatably connected to the side wall of the pressure plates 16.

[0043] When multiple pressure plates 16 need to be moved simultaneously, the first motor 17 is started, which drives the lead screw 18 to rotate. The rotation of the lead screw 18 drives the drive block 19 to move. At the same time, under the action of multiple connecting rods 20, multiple pressure plates 16 can be moved simultaneously.

[0044] The drive assembly includes a second motor 21 fixed to the bottom of the second frame 2, a first pulley 22 fixed to the output end of the second motor 21, a second pulley 23 fixed to the protruding end of the rotating wheel 5 passing through the second frame 2, and a belt 24 installed between the first pulley 22 and the second pulley 23.

[0045] When it is necessary to drive the take-up roller 6 to rotate, the second motor 21 is started, which drives the first pulley 22 to rotate. The rotation of the first pulley 22 drives the second pulley 23 to rotate through the belt 24. The rotation of the second pulley 23 drives the rotating wheel 5 to rotate, thereby driving the take-up roller 6 to rotate.

[0046] There are two sets of fixed mechanisms arranged symmetrically.

[0047] It improves the fixation of the paper core, ensuring that the paper core will not slip.

[0048] Working principle:

[0049] When the fiberglass cloth needs to be wound up, remove the nut 14 to disassemble the winding roller 6. Then, insert the paper core into the side wall of the winding roller 6, insert the locking blocks 12 at both ends of the winding roller 6 into the locking slots 11, and screw the nut 14 onto the threaded rod 13 to fix the winding roller 6 in the desired position. After adjusting the position of the paper core, start the first motor 17 to drive the lead screw 18 to rotate. The rotation of the lead screw 18 drives the drive block 19 to move. At the same time, under the action of multiple connecting rods 20, multiple pressure plates 16 are moved outward and pressed against the inner wall of the paper core, thereby fixing the paper core in the desired position. Then, the fiberglass cloth... After passing through multiple conveyor rollers 3 and tension rollers 4 in sequence, the extended end is wrapped around the side wall of the paper core. Then, the second motor 21 is started, which drives the first pulley 22 to rotate. The rotation of the first pulley 22 drives the second pulley 23 to rotate through the belt 24. The rotation of the second pulley 23 drives the rotating wheel 5 to rotate, which in turn drives the winding roller 6 to rotate. The rotation of the winding roller 6 drives the paper core to rotate, thus winding up the fiberglass cloth. When it is necessary to adjust the tension of the fiberglass cloth during winding, the cylinder 10 is started, which drives the moving block 9 to move. The movement of the moving block 9 drives the tension roller 4 to move through the pulley 8, so that the tension of the fiberglass cloth during winding can be adjusted as needed.

[0050] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
