Description

Technical Field

[0001] The utility model relates to the technical field of winding machines, in particular to an intelligent tension regulating device for a winding machine. Background Art

[0002] Winding machines are mainly used for winding hose lines, nylon, polyester cords, polyester ropes, high-tech fibers, coated yarns, artificial grass yarns, lithium-ion battery production, coated glass fibers, monofilaments, multifilament flat yarns (monofilament or multi-end line spindles), staggered spindles and other fields. The tension of the winding machine needs to be adjusted through the tension adjustment device when in use.

[0003] As disclosed in the application number 202220605508.4, a tension adjustment device for a winding machine is disclosed. The utility model inserts the support plate into the rectangular slot, then inserts the T-shaped block into the T-shaped slot, and then pushes the connecting plate to move in the direction of the support plate, the connecting plate drives the locking block and the connecting block to move to the right, the locking block is stuck in the locking slot, and the T-shaped block is fixed in the T-shaped slot. At the same time, the connecting block drives the pushing plate to move to the right, and the pushing plate drives the clamping block to be stuck to the right into the clamping slot, and the support plate is fixed in the rectangular slot to complete the assembly, which is convenient for assembly and saves time and effort during assembly. However, the tension adjustment device of the winding machine directly pulls the movable adjustment roller body when adjusting the tension. The material itself has tensioning force during adjustment. The sudden pulling adjustment will produce instantaneous tension changes, which are very likely to cause the material to tear and break, affecting the normal transportation of the material. In addition, the roller body is also fixedly installed, which is not convenient for disassembly and maintenance.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an intelligent tension adjustment device for a winding machine is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide an intelligent tension adjustment device for a winding machine to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an intelligent tension adjustment device for a winding machine, comprising a mounting plate, a connecting block is provided on the front side of the mounting plate, a damping spring rod is fixedly installed on the inner surface of the connecting block, a movable block is fixedly installed on the upper end of the damping spring rod, fixed blocks are fixedly installed on the left and right sides of the surface of the mounting plate, shafts are rotatably provided on the front sides of the surfaces of the fixed block and the movable block, rollers are sleeved on the surface of the shaft, connecting mechanisms are provided on the upper and lower sides of the front surface of the shaft, and positioning grooves are provided on the upper and lower sides of the front inner surface of the roller.

[0007] Preferably, the damping spring rod is composed of a damper and a telescopic spring, and the connecting end of the movable block and the damping spring rod is located inside the groove body of the connecting block and slides.

[0008] Preferably, the connecting mechanism includes a constriction groove provided on the upper and lower sides of the front surface of the shaft, and a thrust spring is fixedly installed on the inner surface of the constriction groove.

[0009] Preferably, the connecting mechanism further comprises a bevel block fixedly mounted on the opposite end of the thrust spring, and the height of the bevel block is smaller than the depth of the positioning groove.

[0010] Preferably, a groove is provided in the middle of the front side of the surface of the mounting plate, and a lead screw is rotatably provided on the inner surface of the groove.

[0011] Preferably, the upper end of the lead screw passes through the mounting plate and is provided with a drive motor, and the surface of the lead screw is threadedly connected with a propulsion seat.

[0012] Preferably, the left, right and rear surfaces of the propulsion seat are in sliding contact with the inner surface of the groove, and the front end of the propulsion seat is fixed to the connecting block.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The utility model is provided with a groove, a lead screw, a drive motor, a propulsion seat and a connecting block. The drive motor drives the lead screw to rotate. Under the limit of the groove, the propulsion seat moves up and down, thereby driving the connecting block to move up and down, which can drive the middle roller to adjust up and down, thereby flexibly adjusting the position of the middle roller. In conjunction with the rollers at fixed positions on the left and right sides, the tension during the winding process can be automatically adjusted.

[0015] 2. The utility model provides a damping spring rod and a movable block. When the middle roller moves up and down, the material has a certain tension, which will press the movable block downward to squeeze the damping spring rod, or the damping spring rod will push the movable block upward. In the process of adjusting the tension, the middle roller can provide a certain prestress buffer for the tension. When the middle roller is pulled up to increase the tension, the material can be prevented from being broken by the instantaneous upward pulling force. When the middle roller moves down to release the tension, the material can be supported to avoid the material from sinking and dragging in the middle. This fully ensures the safety and stability of the material during tension adjustment.

[0016] 3. The utility model is provided with a connecting mechanism, a gathering groove, a thrust spring, a bevel block and a positioning groove, and the roller is inserted into the shaft rod. The bevel block can be pushed by the bevel block to squeeze the thrust spring and retract into the gathering groove. When the bevel block is flush with the positioning groove, it will extend under the action of the thrust spring and be inserted into the positioning groove, so that the roller can be positioned and assembled. However, at this time, the bevel block is not fully inserted into the positioning groove. The front and rear sides of the bevel block are relative to the opening edge of the positioning groove by the bevel. Therefore, manual force is applied to move the roller, and the bevel block can also be pushed to retract by the bevel from the back side to complete the disassembly. However, during use, the roller will rotate due to the material moving force, and the shaft rod will also rotate. At this time, centrifugal force will be generated, and the centrifugal force will cause the thrust spring to further expand and extend outward, thereby pushing the bevel block completely into the positioning groove. At this time, the bevel block will be relative to the edge of the positioning groove in a flat position, thereby preventing it from falling off. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1-Figure 3As shown, an intelligent tension adjustment device for a winding machine includes a mounting plate 1, a connecting block 6 is provided on the front side of the mounting plate 1, a damping spring rod 7 is fixedly installed on the inner surface of the connecting block 6, a movable block 8 is fixedly installed on the upper end of the damping spring rod 7, fixed blocks 9 are fixedly installed on the left and right sides of the surface of the mounting plate 1, and a shaft 10 is rotatably provided on the front sides of the surfaces of the fixed block 9 and the movable block 8, a roller 11 is sleeved on the surface of the shaft 10, a connecting mechanism 12 is provided on the upper and lower sides of the front surface of the shaft 10, and a positioning groove 13 is provided on the upper and lower sides of the inner surface of the roller 11; the damping spring rod 7 is composed of a damper and a telescopic spring, and the connecting end of the movable block 8 and the damping spring rod 7 is located in the groove body of the connecting block 6 and slides.

[0023] By adopting the above technical solution, when the middle roller 11 moves up and down, the material has a certain tensioning force, which will press the movable block 8 downward to squeeze the damping spring rod 7, or the damping spring rod 7 will push the movable block 8 upward; during the tensioning process, the middle roller 11 can perform a certain prestressed buffering of the tensioning force. When the middle roller 11 is pulled up to increase the tension, the instantaneous upward pulling force can be avoided to cause the material to break. When the middle roller 11 moves down to release the tension, it can ensure that the material is supported to avoid the situation where the material sinks and drags in the middle.

[0024] Furthermore, the connecting mechanism 12 includes a converging groove 1201 provided on the upper and lower sides of the front surface of the shaft 10, and a thrust spring 1202 is fixedly installed on the inner surface of the converging groove 1201; the connecting mechanism 12 also includes a bevel block 1203 fixedly installed on the opposite end of the thrust spring 1202, and the height of the bevel block 1203 is less than the depth of the positioning groove 13.

[0025] By adopting the above technical solution, the roller 11 is inserted into the shaft 10, and the inclined surface can push the inclined head block 1203 to squeeze the thrust spring 1202 to retract into the convergence groove 1201. When the inclined head block 1203 is flush with the positioning groove 13, it will extend under the action of the thrust spring 1202 and insert into the positioning groove 13, so that the roller 11 can be positioned and assembled.

[0026] The bevel block 1203 is inserted into the positioning slot 13 by means of the thrust spring 1202, but is not completely inserted into the positioning slot 13. The front and rear sides of the bevel block 1203 are both inclined and face the edges of the opening of the positioning slot 13. Therefore, by manually applying force to move the roller 11, the bevel block 1203 can be retracted by means of the inclined surfaces from the rear side, thereby completing the disassembly.

[0027] During use, the roller 11 will rotate due to the material moving force, and the shaft 10 will also rotate, which will generate centrifugal force. The centrifugal force will cause the thrust spring 1202 to further expand and extend outward, thereby pushing the bevel block 1203 completely into the positioning groove 13. At this time, the bevel block 1203 will be in a flat position relative to the edge of the positioning groove 13, thereby preventing it from falling off and ensuring stable use.

[0028] Furthermore, a groove 2 is opened in the middle of the front side of the surface of the mounting plate 1, and a screw 3 is rotatably arranged on the inner surface of the groove 2; the upper end of the screw 3 passes through the mounting plate 1 and is installed with a drive motor 4, and the surface of the screw 3 is threadedly connected to a propulsion seat 5; the left, right and rear surfaces of the surface of the propulsion seat 5 are slidably fitted with the inner surface of the groove 2, and the front end of the propulsion seat 5 is fixed to the connecting block 6.

[0029] By adopting the above technical solution, the driving motor 4 drives the screw 3 to rotate, and under the limit of the groove 2, the propulsion seat 5 moves up and down, thereby driving the connecting block 6 to move up and down, thereby driving the middle roller 11 to move up and down, and cooperating with the rollers 11 in fixed positions on the left and right sides, the tension during the winding process can be automatically adjusted.

[0030] Working principle: When using the intelligent tension adjustment device of the winding machine, first, the roller 11 is inserted into the shaft 10, and the inclined surface can be used to push the inclined head block 1203 to squeeze the thrust spring 1202 to shrink into the convergence groove 1201. When the inclined head block 1203 is flush with the positioning groove 13, it will extend under the action of the thrust spring 1202 and insert into the positioning groove 13, so that the roller 11 can be positioned and assembled. However, at this time, the inclined head block 1203 is not fully inserted into the positioning groove 13. The front and rear sides of the inclined head block 1203 are relative to the opening edge of the positioning groove 13 by the inclined surface, so manual operation is required. The roller 11 can be moved by force, and the inclined surface can be used to push the inclined head block 1203 to shrink from the back side to complete the disassembly. Then the material is pulled around the left roller 11 from below, around the middle roller 11 from above, and around the right roller 11 from below, and finally the material is led out. As the material is pulled by the collecting equipment, the roller 11 will rotate under the material moving force, and the shaft 10 will also rotate. At this time, centrifugal force will be generated, and the centrifugal force will cause the thrust spring 1202 to further expand and extend outward, thereby pushing the inclined head block 1203 completely into the positioning groove 13. At this time, the inclined head block 12 03 will be in a flat position relative to the edge of the positioning groove 13 to prevent it from falling off. As the material is continuously wound and collected, the diameter of the roller collected at the rear side changes, and the tensioning force needs to be adjusted. The driving motor 4 drives the lead screw 3 to rotate. Under the limit of the groove 2, the propulsion seat 5 moves up and down, thereby driving the connecting block 6 to move up and down, and the middle roller 11 can be driven to adjust up and down, thereby flexibly adjusting the position of the middle roller 11. In combination with the rollers 11 fixed on the left and right sides, the tension in the winding process can be automatically adjusted. When the middle roller 11 moves up and down, the material has a certain The tensioning force will press down the movable block 8 to squeeze the damping spring rod 7, or the damping spring rod 7 will push the movable block 8 upward, so that the middle roller 11 can perform a certain prestressed buffer on the tensioning force during the tension adjustment process. When the middle roller 11 is pulled up to increase the tension, the instantaneous upward pulling force can be avoided to cause the material to break. When the middle roller 11 moves down to release the tension, it can ensure that the material is supported to avoid the situation where the material sinks and drags in the middle, thereby fully ensuring the safety and stability of the material during tension adjustment. This is the working principle of the intelligent tension adjustment device of the winding machine.
