Description

Technical Field

[0001] The invention relates to a traction cooling device, belonging to the technical field of conveyor lines. Background Art

[0002] During the cooling operation of the traction roller, a cylindrical cover is provided at each end. The function of the cylindrical cover is to limit the spraying range of the cooling water. During the cooling process of the traction roller, the cylindrical covers provided at both ends can limit the spraying range of the cooling water. After the cooling water enters the cylindrical cover, it will directly spray on the connecting shaft connecting the traction roller and the motor. By cooling the connecting shaft, it prevents the heat from being transferred to the motor through the traction roller and the connecting shaft when the traction roller pulls high-temperature materials, thereby protecting the motor. However, the connecting shaft currently adopts a solid structure, and the cooling water can only contact its surface. The interior cannot come into contact with the cooling water, resulting in the cooling effect of the connecting shaft being difficult to meet actual needs, and the risk of heat being transferred to the motor still exists. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the present invention aims to provide a traction cooling device to solve the problems raised in the above background technology.

[0004] The top end face of said sliding arm is fixedly provided with a toothed connecting strip which is cooperatively connected with said toothed connecting strip.

[0005] Specifically, a circular plate is provided on the side of the connecting plate away from the blind plate, the connecting shaft passes through the circular plate, and there is a gap between the circular plate and the connecting plate, the circular plate is connected and fixed to the cylinder cover, and an edge ring plate is installed on the side of the cylinder cover away from the circular plate, the edge ring plate is sleeved on the blind plate, the inner diameter of the edge ring plate is larger than the outer diameter of the blind plate, two thin tubes are installed at the lower position of the outer surface of the cylinder cover, the two spaces formed by the two water retaining ring plates and the circular plate and the edge ring plate are respectively communicated with the two thin tubes, and a collecting pipe for connecting the cooling water return pipe is installed at the lower end of the drain pipe, one end of the collecting pipe is closed, and the end of the thin tube away from the cylinder cover is connected to the collecting pipe.

[0006] Specifically, a guide ring plate is sleeved on the blind plate and fixedly connected to the blind plate. The guide ring plate is arranged between the edge ring plate and a water retaining ring plate. The outer diameter of the guide ring plate is smaller than the inner diameter of the cylinder cover.

[0007] Specifically, an inner ring is installed in the middle of the side of the connecting disk facing the connecting shaft, and an outer ring is sleeved on the inner ring. The inner diameter of the outer ring is the same as the outer diameter of the inner ring. The outer ring is installed in the circular ring plate, and the inner and outer rings are arranged concentrically with the connecting shaft.

[0008] Specifically, the shaft is provided with a plurality of oblong openings penetrating the shaft at equal intervals in a ring shape, and the oblong openings are arranged along the length direction of the shaft.

[0009] Specifically, a plurality of spiral blades are installed in an annular shape at equal intervals on the outer surface of the shaft rod. The spiral blades are arranged along the length direction of the shaft rod. The oblong opening and the spiral blades are both arranged between two water retaining ring plates.

[0010] Specifically, three first plug sleeves are installed in a ring shape and equidistantly on one side of the blind plate facing the connecting disk, and three second plug sleeves are installed in a ring shape and equidistantly on one side of the connecting disk facing the blind plate. The two ends of the shaft are respectively inserted into the first plug sleeve and the second plug sleeve.

[0011] Specifically, a gear box is installed on the outer side of one of the brackets, the output end of the gear box is connected to a connecting shaft, and a motor is installed on the side of the gear box away from the bracket, and the output shaft of the motor is connected to the input end of the gear box.

[0012] Beneficial effects of the present invention: 1. Three shafts are used to connect the blind plate and the connecting plate. Therefore, when the motor is working, the motor drives the traction roller to rotate through the structure formed by the gear box, connecting shaft, connecting plate, shaft and blind plate. As a result, the gaps between the three shafts are larger. At the same time, the diameter of the shaft is small. Therefore, after the cooling water is poured on the shaft, compared with the connecting shaft with a larger outer diameter, the heat taken away by the cooling water per unit time is increased, thereby improving the effect of preventing the heat on the traction roller from being transferred to the motor.

[0013] 2. Three shafts arranged equidistantly in a ring are inserted between the connecting plate and the blind plate. An oblong opening is opened on the shaft and spiral blades are installed. After the cooling water flows into the cylinder cover through the water outlet of the water distribution pipe, it is guided by the spiral blades to form a spiral water flow on the surface of the shaft. That is, the spiral blades on the outer surface of the shaft rotate with the traction roller, pushing the cooling water to flow spirally along the shaft, increasing the contact time between the cooling water and the shaft. At the same time, the water enters the interior of the shaft through the oblong opening to achieve double-sided cooling of the shaft inside and outside. Compared with the traditional solid structure, the cooling efficiency is improved, and efficient cooling of the connecting shaft and motor protection are achieved. It is suitable for high-temperature material traction scenarios and provides reliable guarantee for the long-term and stable operation of the conveyor line equipment.

[0014] 3. Under the restriction of the two water-retaining ring plates, the cooling water splashing on the shaft is limited to a certain range. When part of the cooling water diffuses from the internal space of the water-retaining ring plate, under the restriction of the side ring plate and the circular ring plate, the splashed water will flow into the collecting pipe connected to the cooling water return pipe through the capillary tube, preventing the cooling water from splashing outside the cylinder cover at will, which is conducive to maintaining the cleanliness of the working environment.

DETAILED DESCRIPTION

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] See also Figures 1-8 The present invention provides a technical solution: a traction cooling device, comprising a connecting beam 1, brackets 4 are installed at both ends of the connecting beam 1, a horizontally arranged traction roller 2 is provided between the two brackets 4, blind plates 18 are installed at both ends of the traction roller 2, and connecting shafts 13 are provided on the backs of the two blind plates 18. The connecting shaft 13 is connected to the bracket 4 through a bearing seat 9, and a connecting disk 14 is installed at one end of the connecting shaft 13 close to the blind plate 18. Three shaft rods 19 arranged in an annular shape and at equal distances are provided between the connecting disk 14 and the blind plate 18. Three first plug sleeves 20 are installed in an annular shape and at equal distances on the side of the blind plate 18 facing the connecting disk 14. On one side, three second plug-in sleeves 24 are installed in a circular shape and at equal intervals, so that the two ends of the shaft 19 are respectively inserted into the first plug-in sleeve 20 and the second plug-in sleeve 24, so that the shaft 19 is plugged into the connecting disk 14 and the blind plate 18. A gear box 5 is installed on the outer side of a bracket 4, and the output end of the gear box 5 is connected to a connecting shaft 13. A motor 6 is installed on the side of the gear box 5 away from the bracket 4, and the output shaft of the motor 6 is connected to the input end of the gear box 5. When the motor 6 is working, the motor 6 drives the traction roller 2 to rotate through the structure formed by the gear box 5, the connecting shaft 13, the connecting disk 14, the shaft 19 and the blind plate 18, thereby providing power for the transmission of high-temperature items.

[0018] See Figures 1-9A barrel cover 3 is provided between the blind plate 18 and the connecting plate 14. The connecting plate 14 and the blind plate 18 are both provided inside the barrel cover 3. Two symmetrically arranged water retaining ring plates 17 are installed inside the barrel cover 3. The end of the shaft rod 19 passes through the water retaining ring plate 17. A pipe joint 8 for connecting the cooling water supply pipe is installed at the upper position of the outer surface of the barrel cover 3. A water distribution pipe 22 is installed at one end of the pipe joint 8 inside the barrel cover 3. A plurality of water outlet holes 26 are evenly opened at the lower position of the outer surface of the water distribution pipe 22. A drain pipe 11 is installed at the lower position of the outer surface of the barrel cover 3. Three shaft rods 19 are used to connect the blind plate 18 and the connecting plate 14. When the motor 6 is working, the power is transmitted to the connecting shaft 13 through the gear box 5, and then the traction roller 2 is driven to rotate through the transmission structure formed by the connecting plate 14, the shaft rod 19 and the blind plate 18. Since the three shaft rods 19 are arranged in a circular shape with equal spacing, a large gap is formed between each other, and the diameter of the shaft rod 19 is smaller than that of the traditional connecting shaft 13. When cooling water is applied to shafts 19, the smaller diameter allows for a relatively larger surface area per unit area, ensuring more complete contact with the cooling water. The larger gaps between shafts 19 facilitate the circulation of cooling water and heat exchange. Compared to conventional connecting shafts 13 with larger outer diameters, this structure significantly increases the amount of heat removed by the cooling water per unit time, effectively preventing heat from the traction roller 2 from being transferred to the motor 6 through the connecting structure, thereby enhancing protection for the motor 6.

[0019] See Figure 1-Figure 7 , a circular ring plate 7 is provided on the side of the connecting disk 14 away from the blind plate 18, and the connecting shaft 13 passes through the circular ring plate 7. There is a gap between the circular ring plate 7 and the connecting disk 14, the circular ring plate 7 is connected and fixed to the cylinder cover 3, and an edge ring plate 21 is installed on the side of the cylinder cover 3 away from the circular ring plate 7. The edge ring plate 21 is sleeved on the blind plate 18, and the inner diameter of the edge ring plate 21 is larger than the outer diameter of the blind plate 18. Two thin tubes 10 are installed at the lower position of the outer surface of the cylinder cover 3. The two spaces formed by the two water retaining ring plates 17 and the circular ring plates 7 and the edge ring plates 21 are respectively communicated with the two thin tubes 10, and the lower end of the drain pipe 11 is provided with a collection pipe 12 for connecting the cooling water return pipe. One end of the collection pipe 12 is closed, and the end of the thin tube 10 away from the cylinder cover 3 is connected to the collection pipe 12. Under the limiting action of the two water retaining ring plates 17, the cooling water sprinkled on the shaft rod 19 is strictly limited to a specific area inside the cylinder cover 3. When some cooling water diffuses from the interior of water retaining ring plate 17 due to the rotation of shaft 19 or the impact of water flow, the closed structure formed by side ring plate 21 and circular ring plate 7 effectively blocks the splashing water. The diffused cooling water flows through the capillary tube 10 on the outer surface of the hood 3 into the manifold 12, and then connects to the cooling water return pipe through the manifold 12, forming a complete water circulation path, completely preventing cooling water from splashing outside the hood 3 and maintaining a clean working environment.

[0020] Furthermore, a guide ring plate 27, fixedly mounted on the blind plate 18 and located between the edge ring plate 21 and one of the water retaining ring plates 17, has an outer diameter smaller than the inner diameter of the drum housing 3, forming an annular guide space. When cooling water splashes onto the surface of the blind plate 18, the guide ring plate 27 guides the water along its outer wall toward the bottom of the drum housing 3, preventing the water from spreading toward the traction roller 2 and avoiding sudden changes in the surface temperature of the traction roller 2 due to contact with the cooling water, further ensuring the stability and durability of the equipment.

[0021] See Figure 1-Figure 5 、 Figure 9 An inner ring 16 is installed in the middle position of the side of the connecting disk 14 facing the connecting shaft 13, and an outer ring 15 is sleeved on the inner ring 16. The inner diameter of the outer ring 15 is the same as the outer diameter of the inner ring 16. The outer ring 15 is installed in the circular ring plate 7. The inner ring 16 and the outer ring 15 are concentrically arranged with the connecting shaft 13. The structure formed by the inner ring 16, the outer ring 15 and the circular ring plate 7 supports the position of the barrel cover 3 without affecting the rotation of the connecting shaft 13. At the same time, after the pipe joint 8 is connected to the cooling water supply pipe and the collecting pipe 12 is connected to the cooling water return pipe, the cooling water supply pipe, the cooling water return pipe, the inner ring 16, the outer ring 15 and the circular ring plate 7 work together to limit the position of the barrel cover 3.

[0022] See Figure 5-Figure 8 The shaft 19 is provided with a plurality of oblong openings 25 equidistantly arranged in a circular pattern, penetrating the shaft 19. The oblong openings 25 are arranged along the length of the shaft 19. The outer surface of the shaft 19 is provided with a plurality of spiral blades 23 equidistantly arranged in a circular pattern, and the spiral blades 23 are arranged along the length of the shaft 19. The oblong openings 25 and the spiral blades 23 are both arranged between the two water retaining ring plates 17. The three shafts 19 equidistantly arranged in a circular pattern are inserted between the connecting plate 14 and the blind plate 18. The shaft 19 is provided with oblong openings 25 and is provided with spiral blades 23. After the cooling water is evenly poured into the cylinder cover 3 through the outlet holes 26 of the water distribution pipe 22, the spiral blades 23 on the outer surface of the shaft 19 rotate synchronously with the traction roller 2. With the guiding effect of the spiral rise angle, the cooling water is forced to form a spiral water flow close to the surface of the shaft 19. This spiral flow pattern extends the contact path between the cooling water and the shaft 19 from a linear spray to a spiral trajectory, increasing the contact time. At the same time, part of the cooling water penetrates into the interior through the oblong opening 25 on the shaft 19, forming a double-sided cooling mechanism of "external spiral flushing + internal convection heat exchange".

[0023] This cooling solution utilizes dynamic spiral water flow to enhance heat exchange. Combined with the hollow shaft's internal and external through-hole structure, it completely resolves the traditional solid shaft's inherent problem of surface cooling and internal heat storage. It is particularly well-suited for high-temperature traction applications such as film stretching and metal strip rolling. Even with material temperatures reaching 200°C, it can ensure continuous operation of conveyor line equipment for over 12 hours without overheating, providing reliable cooling support for long-term, stable industrial production.

[0024] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
