Description

Technical Field

[0001] This utility model belongs to the technical field of winding equipment, specifically an automatic winding equipment for thermal resistance wire. Background Technology

[0002] Resistance temperature detectors (RTDs) are the core components of temperature sensors, which are based on the characteristic that the resistance of a metal changes with temperature. They are usually made of pure metal and work by utilizing the property that the resistance of a metal conductor increases linearly with temperature. By measuring the change in resistance, temperature can be accurately sensed.

[0003] A search revealed that the utility model patent with publication number CN212374596U discloses a device for tightly winding resistance wire. The background section mentions that existing resistance wire winding devices mostly use a motor-driven winding mechanism to complete the winding. This winding mechanism consists of a rotating shaft and a winding post. During the winding process, the resistance wire is prone to loosening, resulting in incomplete winding. Furthermore, the motor-driven winding mechanism has high operating costs. This device addresses this issue by designing a winding wheel. The winding wheel causes a turntable to slide to the right along a connecting rod and compress a spring. The end of the resistance wire is then placed in the groove of the winding wheel. Under the pushing force of the compressed spring's return, the turntable slides to the left along the connecting rod and rotates along the screw. The leftward rotation of the turntable simultaneously drives the winding wheel to rotate, achieving automatic winding without external power and thus reducing operating costs. However, in practical use, this device cannot fix winding wheels with different inner diameters, resulting in low flexibility. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems. This invention provides an automatic winding device for resistance wire, which has the advantage of being able to install winding wheels of different specifications.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic winding device for resistance wire, comprising a base plate, a support plate fixedly installed on the right side of the top of the base plate, a fixed cylinder fixedly sleeved inside the support plate, a collar movably sleeved on the left side of the outer surface of the fixed cylinder, a circular plate fixedly sleeved inside the collar, and three circular rods fixedly installed inside the circular plate. Each of the three circular rods has a movable block movably sleeved on its outer surface, and the outer surface of the movable block is movably connected to the inner surface of the circular plate. A fixed plate is fixedly connected to the left side of the movable block. A partition plate is fixedly sleeved inside the fixed cylinder, and a drive motor is fixedly installed on the right side of the partition plate.

[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] like Figures 1 to 6As shown, this utility model provides an automatic winding device for resistance wire, including a base plate 1, a support plate 2 fixedly installed on the right side of the top of the base plate 1, a fixed cylinder 3 fixedly sleeved inside the support plate 2, a collar 4 movably sleeved on the left side of the outer surface of the fixed cylinder 3, a circular plate 5 fixedly sleeved inside the collar 4, and three circular rods 6 fixedly installed inside the circular plate 5. Movable blocks 7 are movably sleeved on the outer surfaces of the three circular rods 6, and the outer surfaces of the movable blocks 7 are movably connected to the inner surface of the circular plate 5. A fixed plate 8 is fixedly connected to the left side of the movable blocks 7. A partition plate 9 is fixedly sleeved inside the fixed cylinder 3, and a drive motor 10 is fixedly installed on the right side of the partition plate 9. A threaded rod 11 is fixedly connected to the other end of the output shaft of the drive motor 10. A threaded sleeve 12 is fitted with a circular sleeve 12, and a mounting block 13 is movably fitted onto the outer surface of the circular sleeve 12. A hinge rod 14 is hinged to the inside of the side of the mounting block 13, and the other end of the hinge rod 14 is hinged to the right side of the moving block 7. The operator places the winding wheel on the outer surface of the three fixed plates 8, and then starts the drive motor 10, causing the threaded rod 11 to drive the circular sleeve 12 to move to the left, which in turn causes the circular sleeve 12 to drive the mounting block 13 to move to the left. This, in turn, pushes the three moving blocks 7 to move outward along the outer surface of the three circular rods 6 through the hinge rod 14, thereby causing the fixed plates 8 to move outward, which in turn supports the winding wheel. When the collar 4 rotates, it will drive the circular plate 5 to rotate, which will cause the hinge rod 14 to drive the mounting block 13 to rotate on the outer surface of the circular sleeve 12.

[0023] Among them, a limiting rod 15 is fixedly installed on the left side of the partition 9. There are two limiting rods 15, which are located at the front and rear sides of the threaded rod 11, respectively. The left end of the limiting rod 15 passes through the sleeve 12 and extends to the left side of the sleeve 12 and is movably sleeved with the inner wall of the sleeve 12. By setting the limiting rod 15, the limiting rod 15 can restrict the sleeve 12, prevent the sleeve 12 from rotating, and can move the sleeve 12 left and right without affecting it.

[0024] Each of the limiting rods 15 has a connecting plate 16 fixedly connected to its left end, and the right side of the connecting plate 16 is movably connected to the left end of the threaded rod 11. By setting the connecting plate 16, the connecting plate 16 can connect the two limiting rods 15, thereby making the limiting rods 15 more stable.

[0025] Among them, the outer surface of the fixing plate 8 is fixedly installed with an anti-slip pad 17, and the outer surface of the collar 4 is fixedly sleeved with a driven roller 18; by setting the anti-slip pad 17, the anti-slip pad 17 can play an anti-slip role, thereby making the winding wheel more stable to be supported and fixed.

[0026] The support plate 2 has a fixed sleeve with a power motor 19 located below the fixed cylinder 3. The other end of the output shaft of the power motor 19 is fixedly connected to a round shaft 20. The outer surface of the round shaft 20 is fixedly sleeved with a drive roller 21. The drive roller 21 is connected to the driven roller 18 through a transmission belt 22. When the power motor 19 is started, the round shaft 20 will drive the drive roller 21 to rotate, thereby driving the driven roller 18 to rotate through the transmission belt 22. This will cause the collar 4 to drive the round plate 5 to rotate, so that the supported winding wheel can rotate, thereby winding the thermal resistance wire.

[0027] A fixed box 23 is fixedly installed on the front side of the top of the base plate 1. A fixed motor 24 is fixedly installed on the right side of the fixed box 23. A lead screw 25 is fixedly connected to the other end of the output shaft of the fixed motor 24. The outer surface of the lead screw 25 is movably sleeved with the inner wall of the fixed box 23. A movable plate 26 is threadedly sleeved on the outer surface of the lead screw 25. The outer surface of the movable plate 26 is movably connected with the inner surface of the fixed box 23. When the fixed motor 24 is started, the lead screw 25 will drive the movable plate 26 to move along the inside of the fixed box 23.

[0028] The top of the movable plate 26 is fixedly connected to a vertical rod 27, and a guide cylinder 28 is fixedly installed on the top of the vertical rod 27. The operator passes the resistance wire through the guide cylinder 28, so that when the guide cylinder 28 moves left and right, it can drive the resistance wire to move left and right, so that the resistance wire can be wound more evenly.

[0029] Working principle and usage process of this utility model:

[0030] When the operator needs to wind the resistance wire, he first puts the winding wheel on the outer surface of the three fixed plates 8, and then starts the drive motor 10, so that the threaded rod 11 drives the round sleeve 12 to move to the left under the limiting action of the limiting rod 15. At this time, the round sleeve 12 will drive the mounting block 13 to move to the left, so that the hinge rod 14 pushes the moving block 7 to move along the outer surface of the round rod 6, so that the three moving blocks 7 can move outward at the same time, and then the three fixed plates 8 will support and fix the winding wheel from the inside.

[0031] Then, the operator passes one end of the resistance wire through the guide cylinder 28 and fixes it to the winding wheel. Then, the fixed motor 24 and the power motor 19 are started. The start of the fixed motor 24 will cause the lead screw 25 to drive the moving plate 26 to move, thereby driving the resistance wire to move left and right through the vertical rod 27 and the guide cylinder 28, so that the resistance wire can be evenly wound on the outer surface of the winding wheel. The start of the power motor 19 will cause the round shaft 20 to drive the drive roller 21 to rotate. The drive roller 21 drives the driven roller 18 to rotate through the cooperation of the transmission belt 22, thereby driving the round plate 5 to rotate through the collar 4, and thus causing the winding wheel to rotate, thereby winding the resistance wire.
