Description

Technical Field

[0001] This utility model relates to the field of warping machine technology, specifically to a tension adjustment device for a warping machine. Background Technology

[0002] As is well known, a warping machine is a device that winds multiple warp yarns parallel to each other on a warp beam according to specified lengths and widths. The tension regulating device is one of the core components of the warping machine. Its function is to control the tension of the warp yarns to ensure that the tension is uniform during the winding process, thus avoiding problems such as uneven winding of the warp beam, yarn breakage, or a decline in the quality of subsequent weaving caused by uneven tension.

[0003] However, in most warping machines on the market, when the tension adjustment device is idle, the conveyor roller is often directly exposed to the external environment without effective protection measures. In this case, the conveyor roller is very easy to suffer surface damage or structural deformation due to accidental collisions with external objects. Especially in scenarios where multiple equipment are operating in the workshop or materials are frequently handled, the risk of collisions increases significantly. Once the conveyor roller is damaged, its surface roughness will change, resulting in uneven friction during yarn transmission, which will affect the tension stability during the warping process. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, this utility model provides a tension adjustment device for a warping machine.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a tension adjustment device for a warping machine, comprising a base plate, an adjustment mechanism, and a protective mechanism. The adjustment mechanism includes a vertical block, a first sliding component, a frame, a movable block, a conveying roller, a guide groove, a limiting frame, a cylinder, a connecting plate, and an electromagnet. The vertical block is disposed on the top of the base plate. The frame is connected to the vertical block via the first sliding component. One end of the movable block is hinged to the inner wall of the frame. One end of the conveying roller is connected to the other end of the movable block via a bearing. The guide groove is formed on the side of the vertical block. The end of the limiting frame extends into the guide groove, and the inner wall of the limiting frame contacts the other end of the conveying roller. One end of the cylinder is connected to the connecting plate, and the other end of the cylinder passes through the limiting frame and extends into the conveying roller. One end of the electromagnet is fixedly connected to the connecting plate, and the other end of the electromagnet attracts the limiting frame. The protective mechanism includes a second sliding component and a protective shell. The protective shell is connected to the base plate via the second sliding component.

[0008] To facilitate operation of the equipment, the present invention is improved by providing a controller on the front of the base plate, the controller being electrically connected to the first sliding component and the controller being electrically connected to the second sliding component.

[0009] To improve stability, this utility model is improved by providing two electromagnets, which are arranged symmetrically.

[0010] To improve stability, this invention is improved by having the guide groove match the end of the frame.

[0012] To improve the connection effect, the present invention is improved by welding the upright block to the base plate.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a tension adjustment device for a warping machine, which has the following advantages:

[0015] This tension adjustment device for warping machines achieves dual optimization of precise tension control and equipment protection through the coordinated design of the adjustment mechanism and the protective mechanism. In the adjustment mechanism, the first sliding component drives the frame to rise and fall, and in conjunction with the hinged structure of the movable block and the conveyor roller, the yarn tension can be adjusted in real time by moving the conveyor roller up and down. The matching design of the limit frame and the guide groove ensures the axial stability of the conveyor roller and avoids slippage. Two symmetrically arranged electromagnets ensure that the limit frame fits the conveyor roller with balanced adsorption force, and the redundant design improves fault tolerance. The protective mechanism drives the protective shell to slide and fit through the second sliding component, isolating the conveyor roller from contact with the outside when the equipment is idle, preventing collision damage and extending the life of the components. In addition, the anti-slip pad at the bottom of the base plate enhances the stability of the equipment placement, and the welded connection between the upright block and the base plate ensures structural rigidity. This structure solves the problem of insufficient protection in traditional devices, reduces maintenance costs, and ensures long-term reliable operation of the equipment. Attached Figure Description

[0021] 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 obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 The tension adjustment device for the warping machine includes a base plate 1, an adjustment mechanism 2, and a protective mechanism 13. The adjustment mechanism 2 includes a vertical block 3, a first sliding assembly 4, a frame 5, a movable block 6, a conveying roller 7, a guide groove 8, a limiting frame 9, a cylinder 10, a connecting plate 11, and an electromagnet 12. The vertical block 3 is disposed on the top of the base plate 1. The frame 5 is connected to the vertical block 3 through the first sliding assembly 4. One end of the movable block 6 is hinged to the inner wall of the frame 5. One end of the conveying roller 7 is connected to the other end of the movable block 6 through a bearing. The guide groove 8 is formed in... On the side of the upright block 3, the end of the limiting frame 9 extends into the guide groove 8, the inner wall of the limiting frame 9 contacts the other end of the conveying roller 7, one end of the cylinder 10 is connected to the connecting plate 11, and the other end of the cylinder 10 passes through the limiting frame 9 and extends into the conveying roller 7. One end of the electromagnet 12 is fixedly connected to the connecting plate 11, and the other end of the electromagnet 12 attracts the limiting frame 9. The protective mechanism 13 includes a second sliding component 14 and a protective shell 15. The protective shell 15 is connected to the base plate 1 through the second sliding component 14.

[0023] Working principle: Place the equipment in the designated position, support it with the base plate 1, and connect it to the external mains power supply. Then, wind the conveying yarn onto the conveyor roller 7. Start the first sliding component 4 (composed of a slide groove, slider, threaded rod, motor, and coupling, etc.). The frame 5 slides on the vertical block 3 through this component, thereby driving the movable block to move up and down, which in turn causes the conveyor roller 7 (connected to the movable block 6 through a bearing) to move up and down. Since the two ends of the yarn are connected to the external feed roller and discharge roller respectively, the raising and lowering of the conveyor roller 7 will change the yarn tension, thereby achieving tension adjustment.

[0024] During this process, the limiting frame 9 extends into the guide groove 8 of the vertical block 3, and its inner wall contacts the other end of the conveyor roller 7, which only limits the axial movement of the conveyor roller 7 (to prevent it from moving). The cylinder 10 passes through the limiting frame 9 and extends into the conveyor roller 7, which will not hinder the conveyor roller 7 from rotating around the bearing. When the conveyor roller 7 moves up and down, the limiting frame 9 slides synchronously in the guide groove 8 to ensure that the conveyor roller 7 is stably displaced in the vertical direction.

[0025] When the equipment is not in use, follow these steps to activate the protective mechanism:

[0026] Turn off the electromagnet 12 to stop it from attracting the martensitic stainless steel limit frame 9.

[0027] Hold the limiting frame 9 and pull the connecting plate 11 to pull the cylinder 10 out of the conveying roller 7. At the same time, the limiting frame 9 descends in the guide groove 8 and disengages from the axial limit of the conveying roller 7.

[0028] Manually rotate the conveyor roller 7 to drive the movable block 6 to rotate 90° within the frame 5 (the inner wall of the frame 5 is provided with a round rod, and the movable block 6 is provided with a round hole, which is fitted onto the outer wall of the round rod, so that the movable block 6 can rotate around the round rod). Then you need to hold the conveyor roller 7.

[0029] Activate the first sliding assembly 4 to raise and lower the conveyor roller 7 to a position aligned with the axis of the protective shell 15;

[0030] Activate the second sliding assembly 14 (with the same structure as the first sliding assembly) to drive the protective shell 15 to slide along the base plate 1, so that it fits precisely on the outside of the conveyor roller 7, isolating it from external impacts and preventing the conveyor roller 7 from being damaged due to long-term exposure.

[0031] The surface of the conveyor roller 7 is plated with hard chrome or sprayed with a ceramic coating, which can improve wear resistance and corrosion resistance.

[0032] To facilitate equipment operation, a controller 16 is installed on the front of the base plate 1 in this embodiment. The controller 16 is electrically connected to the first sliding component 4 (composed of a sliding groove, a slider, a threaded rod, a drive motor, and a coupling, etc.) through a circuit. It can receive and process tension adjustment commands in real time and accurately control the lifting and lowering displacement of the frame 5. At the same time, the controller 16 and the second sliding component 14 (with the same structure as the first sliding component) form an electrical linkage. When the equipment needs to activate the protective function, the sliding engagement action of the protective shell 15 can be triggered by the controller 16 with one button, realizing the integrated intelligent control of the adjustment mechanism and the protective mechanism.

[0033] To improve the stability of the device operation, this embodiment is equipped with two electromagnets 12, which are arranged symmetrically. This symmetrical arrangement can prevent the limiting frame 9 from shifting or vibrating due to unilateral force through balanced adsorption force, ensuring that it is stably attached to the conveyor roller 7 in the guide groove 8. At the same time, the symmetrical structure can also make the conveyor roller 7 uniformly stressed during axial limiting. Combined with the matching structure of the guide groove 8 and the frame 5, it further reduces the lateral swaying of the conveyor roller 7 when it rises and falls. In addition, this redundant design can maintain the basic adsorption function of the other electromagnet when a single electromagnet fails, preventing the limiting frame 9 from accidentally falling off, effectively improving the stability and fault tolerance of the equipment operation.

[0034] To improve the stability and accuracy of the sliding process, the shape and size of the guide groove 8 are precisely matched with the end of the frame 5 in this embodiment. This matching design ensures that when the frame 5 moves up and down along the block 3 via the first sliding component 4, its end can form a stable limiting sliding pair in the guide groove 8. On the one hand, the inner wall of the guide groove 8 forms a lateral constraint on the end of the frame 5, avoiding lateral offset or shaking during the sliding process. On the other hand, the matching gap between the two is precisely designed to ensure that the frame 5 can slide smoothly, and to eliminate unnecessary degrees of freedom through the gap fit, so that the lifting trajectory of the conveyor roller 7 always remains vertical. This enables more precise displacement control during tension adjustment, effectively improving the stability of equipment operation and the accuracy of tension adjustment.

[0035] To improve the anti-slip effect when the equipment is placed, an anti-slip pad is fixedly connected to the bottom of the base plate 1 in this embodiment. The anti-slip pad is made of rubber with a high coefficient of friction and its anti-slip performance is enhanced by the following design: On the one hand, its bottom surface is provided with interlaced tooth-shaped or corrugated anti-slip patterns to increase the contact friction with the placement surface and effectively prevent the equipment from shifting due to vibration during the operation of the warping machine; on the other hand, the anti-slip pad is rigidly fixed to the bottom of the base plate 1 by high-strength adhesive or bolts to ensure that it will not fall off during long-term use. At the same time, the evenly distributed anti-slip pad structure can distribute the weight of the equipment to the entire contact plane, avoiding the risk of tilting caused by uneven local force. This design ensures that the equipment maintains a stable installation state under high-speed warping or frequent tension adjustment conditions, providing basic support for the accurate operation of the tension adjustment mechanism.

[0036] To improve the stability of the connection between the upright block 3 and the base plate 1, this embodiment adopts welding to achieve a rigid connection between the two. Specifically, the bottom of the upright block 3 and the top surface of the base plate 1 form a metal fusion joint through a continuous full welding process. Before welding, the contact surfaces are treated to remove rust and oil to ensure a clean welding interface. During the welding process, a symmetrical welding method is used, with multiple passes for uniform heating to reduce deformation caused by welding stress. After welding, the weld is ground smooth and coated with anti-rust paint to prevent corrosion of the welded parts. This welding connection method can withstand the dynamic load of the warping machine and the frequent lifting and lowering vibration of the adjustment mechanism. Compared with bolt connection or riveting, it eliminates the risk of loosening of the connecting parts, allowing the upright block 3 to always maintain vertical positioning accuracy, providing a solid support foundation for the stable operation of the first sliding component 4 and the frame 5, and ensuring the long-term reliable operation of the tension adjustment device from a structural perspective.
