Currently, the spinning wheels on the market are mostly made of carbide or tool steel, and the surface is coated with a layer of low-friction material to improve wear resistance. However, during the use of the spinning wheel, heat is easily generated, which accelerates the wear of the surface coating and reduces the life of the spinning wheel, ultimately causing defects in the processed products and reducing the quality.

[0009] Through the above technical solution: the spring is connected between the rotating drum and the rotating column, so when the rotating drum rotates, the spring will be deformed by the tensile force and store energy, which gradually increases as the hose is pulled out. When the hose stops being pulled out, that is, there is no external force acting on the hose, the spring begins to release the previously stored rebound force, causing the rotating drum to rotate in the opposite direction, thereby reeling the hose back to its original shape, improving work efficiency and reducing the tediousness of manual operation.

[0011] A water inlet is fixedly connected to the middle of the top wall of the cooling box, a water injection nozzle is fixedly connected to the middle of the top wall of the water inlet, and a water injection cap is threadedly connected to the outer wall of the water injection nozzle.

[0012] Through the above technical solution: the required coolant can be easily injected into the cooling box through the water filling port and the water filling nozzle. The outer wall of the water filling nozzle is threaded and can be tightly connected with the water filling cover to ensure that the coolant in the cooling box will not leak when not in use.

[0015] Through the above technical solution: the limiting ring limits the position of the rotating ring so that it can only rotate within its range, and the two rotating rings are connected by a plastic connecting rope.

[0019] As a further description of the above technical solution:

[0020] A magnet sheet is fixedly connected to the middle portion of the left side of the cooling box.

[0021] Through the above technical solution: the magnet sheet allows the cooling box to be adsorbed at a desired location, but this location must be adsorbable by the magnet sheet, thereby achieving a quick and convenient connection and fixation effect.

[0022] As a further description of the above technical solution:

[0023] The bottom wall of the cooling box is equidistantly connected with a plurality of cooling fins.

[0024] Through the above technical solution: the heat sink is used to increase the contact area between the cooling box and the surrounding environment, so as to more effectively dissipate the heat in the cooling box to the external environment.

[0025] As a further description of the above technical solution:

[0026] The left side of the magnet sheet and the left sides of the plurality of fixing legs are in the same plane.

[0027] Through the above technical solution: since the left side of the magnet sheet and the left sides of the plurality of fixing legs are in the same plane, the cooling box will not be affected no matter which installation method is used.

[0030] 2. In the present invention, a spring is connected between the rotating drum and the rotating column. Therefore, when the rotating drum rotates, the spring will be deformed by the tensile force and store energy, which gradually increases as the hose is pulled out.

DETAILED DESCRIPTION

[0036] 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.

[0037] Reference Figure 1 and Figure 2The utility model provides an embodiment: a wear-resistant and low-friction spinning wheel, comprising a wheel disc 1 and a cooling box 5. The surface of the wheel disc 1 is covered with a wear-resistant and low-friction coating. The top wall of the wheel disc 1 is equidistantly provided with a plurality of engaging holes 3. The front and rear sides of the inner wall of the wheel disc 1 are provided with engaging grooves 4. The rear end of the left side of the outer wall of the wheel disc 1 is fixedly connected to a water inlet 6. The front end of the left side of the outer wall of the wheel disc 1 is fixedly connected to a water outlet 7. The right sides of the water inlet 6 and the water outlet 7 are both connected with a supply pipe 8. The two supply pipes 8 are connected to the cooling box 5. The right ends of the pipes 8 are connected to hollow cooling plates 9, and concave pipes 10 are connected between adjacent hollow cooling plates 9. The front and rear sides of the outer wall of the supply pipe 8 are connected to connecting pipes 11. The middle of the connecting pipe 11 is equidistantly connected to multiple annular ducts 12. Two hoses 13 are connected to the middle of the right side of the cooling box 5. The right end of the rear hose 13 is connected to the left side of the water inlet 6, and the right end of the front hose 13 is connected to the left side of the water outlet 7. A winding device 2 is provided at the front and rear ends of the right side of the cooling box 5.

[0038] Specifically, the core component of the spinning wheel is the wheel disc 1. The top wall of the wheel disc 1 has a plurality of equidistant meshing holes 3, which help to position the wheel disc 1 with the workpiece during the spinning process. The inner wall of the wheel disc 1 is provided with a pair of engaging grooves 4 for fixing and supporting the wheel disc 1 to ensure its stability during high-speed rotation. The water inlet 6 and the water outlet 7 are connected to the hollow cooling plate 9 through the supply pipe 8. The hollow cooling plate 9 is distributed along the circumference of the inner wall of the wheel disc 1 and is connected by the concave pipe 10 to form a circle of cooling ring belt, forming a circulating cooling loop, ensuring that the cooling water can be evenly distributed and fully contact the inner wall of the wheel disc 1, so that the inner wall of the wheel disc 1 and the engaging groove 4 can be effectively cooled, and at the same time connected to the supply pipe 8 There is also a connecting pipe 11, which serves as a connecting channel to connect multiple annular ducts 12 in series. The annular duct 12 surrounds the meshing hole 3 in the wheel disc 1, which can increase the contact area with the meshing hole 3, so that the annular duct 12 can cool the meshing hole 3 to the maximum extent. The cooling box 5 is responsible for storing and circulating cooling water, and is connected to the water inlet 6 and the water outlet 7 through the hose 13 to form a closed cooling water circulation system, which can maintain a low friction coefficient and excellent wear resistance under high load and high-speed operation conditions. At the same time, the cooling system can effectively reduce the temperature of the wheel disc 1, prevent performance degradation or damage due to overheating, and thus extend the service life of the spinning wheel.

[0039] Reference Figure 1 and Figure 3The winding device 2 includes two brackets 201, and the adjacent sides of the two brackets 201 are fixedly connected to the rotating columns 202, and the adjacent sides of the two rotating columns 202 are fixedly connected to the springs 203. The adjacent ends of the two springs 203 are fixedly connected to the fixed blocks 204. The outer walls of the two rotating columns 202 are rotatably connected to the rotating drum 205, and the outer wall of the rotating drum 205 is fixedly connected to a plurality of dividing plates 206 at equal intervals. The top walls of the two fixed blocks 204 are fixedly connected to the top of the inner wall of the rotating drum 205.

[0040] Specifically, the two brackets 201 serve as a fixed basis. A rotating column 202 is fixed on the inner side of each bracket 201. The rotating column 202 enables the rotating drum 205 to rotate on the outer wall of the rotating column 202. A spring 203 is provided on one side of the two rotating columns 202. One end of the spring 203 is fixedly connected to the rotating column 202, and the other end is connected to the fixed block 204 and is connected to the top of the inner wall of the rotating drum 205 through the fixed block 204. When the rotating drum 205 rotates, the spring 203 and the fixed block 204 will move accordingly. When the hose 13 is pulled out, the rotating drum 205 will rotate with the movement of the hose 13. Since the spring 203 is connected between the drum 205 and the rotating column 202, when the drum 205 rotates, the spring 203 will be subjected to a tensile force, deformed and store energy. In this process, the force state of the spring 203 changes dynamically, and it gradually increases with the amount of the hose 13 pulled out. When the hose 13 stops being pulled out, that is, when there is no external force acting on the hose 13, the spring 203 begins to release the previously stored rebound force. This rebound force pushes the fixed block 204 and the drum 205 to rotate in opposite directions, thereby And make the rotating drum 205 return to its original position, because the rebound force of the spring 203 is uniform, the rotation of the rotating drum 205 is also stable, which helps to reel the hose 13 back to its original shape in an orderly manner. A plurality of dividing plates 206 are fixed at equal intervals on the outer wall of the rotating drum 205, which not only enhances the structural strength of the rotating drum 205, but also plays a role in separating the hoses 13, so that the hoses 13 can be arranged in an orderly manner during the reeling process, and the automatic reeling function of the hose 13 can be realized, thereby improving work efficiency and reducing the tediousness of manual operation.

[0041] Reference Figure 1 A water inlet 14 is fixedly connected to the middle of the top wall of the cooling box 5, a water injection nozzle 15 is fixedly connected to the middle of the top wall of the water inlet 14, and a water injection cover 16 is threadedly connected to the outer wall of the water inlet 14; the outer walls of the water inlet 14 and the water injection cover 16 are fixedly connected to two limiting rings 17, and the two upper limiting rings 17 and the two lower limiting rings 17 are rotatably connected to the adjacent rotating rings 18, and the outer walls of the two rotating rings 18 are fixedly connected to plastic connecting ropes 19; a plurality of heat sinks 23 are equidistantly connected to the bottom wall of the cooling box 5;

[0042] Specifically, there is a water inlet 14 in the middle of the top wall of the cooling box 5, through which the required coolant can be easily injected into the cooling box 5. The outer wall of the water inlet 15 is threaded and can be tightly connected to the water inlet cover 16 to ensure that the coolant in the cooling box 5 will not leak out when not in use. The outer walls of the water inlet 14 and the water inlet cover 16 are fixedly connected with a limiting ring 17, and a rotating ring 18 is provided between the two limiting rings 17. The limiting ring 17 limits the position of the rotating ring 18 so that it can only rotate within its range. The two rotating rings 18 are connected by a plastic connecting rope 19. This design enables the water inlet cover 16 to be fixed on the cooling box 5 when not in use and is not easy to lose. The heat sink 23 is used to increase the contact area between the cooling box 5 and the surrounding environment, thereby more effectively dissipating the heat in the cooling box 5 to the external environment.

[0043] Reference Figure 1 The front and rear ends of the left side of the cooling box 5 are fixedly connected to two fixing legs 20, and the inner walls of the multiple fixing legs 20 are each provided with fixing holes 21; a magnet piece 22 is fixedly connected to the middle of the left side of the cooling box 5; the left side of the magnet piece 22 is in the same plane as the left sides of the multiple fixing legs 20;

[0044] Specifically, the fixing legs 20 and the fixing holes 21 allow the cooling box 5 to be installed in an appropriate position by means of bolts or other fasteners, ensuring its stability and position fixation. The magnet sheet 22 allows the cooling box 5 to be adsorbed at a certain position where it is desired to be fixed by means of the magnet sheet 22, but this position must be adsorbed by the magnet sheet 22, thereby achieving a quick and convenient connection and fixing effect. Since the left side of the magnet sheet 22 is in the same plane as the left sides of the multiple fixing legs 20, the cooling box 5 will not be affected no matter which method is used to install it.

[0045] Working principle: The core component of the spinning wheel is the wheel disc 1. The top wall of the wheel disc 1 has multiple equidistant meshing holes 3, which help to position the wheel disc with the workpiece during the spinning process. The inner wall of the wheel disc 1 is provided with a pair of engaging grooves 4 for fixing and supporting the wheel disc 1 to ensure its stability during high-speed rotation. The water inlet 6 and the water outlet 7 are connected to the hollow cooling plate 9 through the supply pipe 8. The hollow cooling plate 9 is distributed along the circumference of the inner wall of the wheel disc 1 and is connected through the concave pipe 10 to form a circle of cooling belt, forming a circulating cooling loop to ensure that the cooling water can be evenly distributed and fully contact the wheel disc. The inner wall portion of the disc 1 enables the inner wall of the wheel disc 1 and the engaging groove 4 to be effectively cooled. At the same time, a connecting pipe 11 is connected to the supply pipe 8. The connecting pipe 11 serves as a connecting channel to connect multiple annular ducts 12 in series. The annular ducts 12 surround the meshing holes 3 in the wheel disc 1, which can increase the contact area with the meshing holes 3, so that the annular ducts 12 can cool the meshing holes 3 to the maximum extent. The cooling box 5 is responsible for storing and circulating cooling water, and is connected to the water inlet 6 and the water outlet 7 through the hose 13 to form a closed cooling water circulation system.

[0046] In addition, the two brackets 201 serve as a fixed basis. A rotating column 202 is fixed on the inner side of each bracket 201. The rotating column 202 enables the rotating drum 205 to rotate on the outer wall of the rotating column 202. A spring 203 is provided on one side of the two rotating columns 202. One end of the spring 203 is fixedly connected to the rotating column 202, and the other end is connected to the fixed block 204 and is connected to the top of the inner wall of the rotating drum 205 through the fixed block 204. When the rotating drum 205 rotates, the spring 203 and the fixed block 204 will move accordingly. When the hose 13 is pulled out, the rotating drum 205 will rotate with the movement of the hose 13. Since the spring 203 is connected between the drum 205 and the rotating column 202, when the drum 205 rotates, the spring 203 will be subjected to a tensile force, deformed and store energy. In this process, the stress state of the spring 203 changes dynamically, and it gradually increases with the amount of the hose 13 pulled out. When the hose 13 stops being pulled out, that is, there is no external force acting on the hose 13, the spring 203 begins to release the previously stored rebound force. This rebound force will push the fixed block 204 and the drum 205 to rotate in opposite directions, thereby causing the drum 205 to return to its original position. A plurality of partition plates 206 are equidistantly fixed on the outer wall of the drum 205, which not only enhances the structural strength of the drum 205, but also serves to separate the hoses 13, so that the hoses 13 can be arranged in an orderly manner during the winding process, thereby realizing the automatic winding function of the hose 13.
