Description

Technical Field

[0001] This utility model mainly relates to the technical field of cam dividers, specifically an active heat dissipation device for cam dividers. Background Technology

[0002] A cam divider, also known as a cam indexer or intermittent divider in engineering, is a high-precision rotary device. Its main function is to convert continuous input motion into intermittent, predetermined output motion. Cam dividers are widely used in automation systems across various fields, including packaging, printing, electronics, pharmaceuticals, tobacco, and automotive manufacturing. For example, in automated production lines, cam dividers can be used in assembly, inspection, and packaging processes; in mechanical transmissions, they can serve as key components to convert between rotary and linear motion. However, cam dividers are prone to internal heat buildup under high loads, which can lead to internal damage over time.

[0003] According to application number 202220889546.7, the pressure-reducing and heat-dissipating cam divider includes a cam divider body, a pressure relief pipe connected to the top of the cam divider body, the pressure relief pipe communicating with the cam divider body, a connecting assembly connecting the pressure relief pipe and the cam divider body, an outer connecting pipe connected to the top of the pressure relief pipe, a tapered tube I fixedly connected to the inner cavity of the pressure relief pipe, a tapered tube II fixedly connected to the bottom of the inner cavity of the outer connecting pipe, a fixed pipe connected to the top of the tapered tube II, a plug extending into the inner cavity of the fixed pipe at the top of the fixed pipe, an elastic pressure-resistant assembly connected between the top of the plug and the outer connecting pipe, and a blocking assembly fixedly connected to the top of the tapered tube I at the inner cavity of the pressure relief pipe.

[0004] The aforementioned document describes a method that involves adding a pressure relief element. The pressure is released through the pressure relief pipe into the tapered tube, thus preventing the cam divider body from generating excessive heat. However, this heat dissipation method suffers from low efficiency and insufficient heat dissipation performance. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an active heat dissipation device for a cam divider to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An active cooling device for a cam divider includes a divider body with two isolation plates mounted on both sides. A dual-output shaft motor is mounted at the middle of one end of each isolation plate. Two input shafts are respectively provided at both ends of the divider body and rotatably mounted on the two isolation plates. Two input shafts are respectively provided at both ends of the dual-output shaft motor and rotatably mounted on the two isolation plates. A drive component connected to the input shaft on one side is provided on one input shaft, and a pump component is provided on the other input shaft. One end of the pump component is sealed and connected to an inlet component communicating with one end of the divider body, and the other end of the pump component is sealed and connected to an outlet component communicating with one side of the divider body. A cooling fan is mounted in the middle of the isolation plate on the other side.

[0008] Preferably, a first rotating sealing ring is installed on the top of the divider body to seal the bottom of the indexing plate, and a second sealing ring is installed on both sides of the divider body to seal the two input shafts. An inner cavity close to the indexing plate and the conjugate cam is opened inside the divider body.

[0009] Preferably, the driving component includes a first gear sleeved on the input shaft, and a second gear sleeved on the input shaft on the same side, wherein the first gear and the second gear are connected by a toothed belt.

[0010] Preferably, the pumping component includes an impeller sleeved on the input shaft, a pump casing mounted on the isolation plate is sleeved on the outside of the impeller, and a third sealing ring is installed at the connection between the input shaft and the pump casing.

[0011] Preferably, the liquid inlet component includes a plurality of first through holes that are laterally opened at one end of the divider body and connected to the inner cavity. The outer cover of the first through holes is fitted with the same number of first guide tubes. One end of the pump housing is provided with a liquid inlet. The liquid inlet is connected to all the first guide tubes through a liquid inlet pipe.

[0012] Preferably, the liquid outlet component includes a plurality of second through holes vertically opened on one side of the divider body and connected to the inner cavity. The outer cover of the second through holes is fitted with the same number of second guide pipes that penetrate the isolation plate. The other end of the pump housing is provided with a liquid outlet. The liquid outlet is connected to all the second guide pipes through a liquid outlet pipe. The second guide pipes and the liquid outlet pipes have multiple bends.

[0013] Preferably, the cooling fan is vertically mounted on the isolation plate, and a driven gear with a fixed connection to the fan blades is provided on one side of the input shaft on the same side of the cooling fan, and a drive gear plate that meshes with the driven gear is sleeved on one end of the input shaft on the same side.

[0014] In summary, this technical solution has the following main advantages:

[0015] This invention achieves circulating heat dissipation of the lubricating oil inside the divider body by designing a pumping component and a cooling fan. Under the action of the rotating indexing plate, the lubricating oil circulates inside the divider body through the inlet and outlet components, effectively carrying away the generated heat. At the same time, the high-speed rotation of the cooling fan further enhances the heat dissipation effect, making the entire heat dissipation process more efficient.

[0016] The heat dissipation efficiency of the device is closely related to the operating state of the main body of the divider. The output angular velocity of the dual-output shaft motor, the speed of the cooling fan, the speed of the impeller, and the speed of the conjugate cam are directly proportional to each other. This means that when the speed of the conjugate cam increases and the heat generation increases, the speed of the cooling fan will also increase accordingly, thereby enhancing the heat dissipation effect. This adaptive heat dissipation adjustment mechanism ensures that the device can maintain stable heat dissipation performance under different operating conditions. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example

[0026] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figures 4 and 6, an active cooling device for a cam divider includes a divider body 10. Two isolation plates 11 are installed on both sides of the divider body 10. A dual-output shaft motor 12 is installed at the middle of one end of each isolation plate 11. Two input shafts 13 are respectively provided at both ends of the divider body 10 and rotatably mounted on the two isolation plates 11. Two output shafts 14 are respectively provided at both ends of the dual-output shaft motor 12 and rotatably mounted on the two isolation plates 11. A drive component 15 connected to the output shaft 14 on one side of the input shaft 13 is provided, and a pump component 16 is provided on the other side of the input shaft 13. One end of the pump component 16 is sealed and connected to an inlet component 17 communicating with one end of the divider body 10, and the other end of the pump component 16 is sealed and connected to an outlet component 18 communicating with one side of the divider body 10. A cooling fan 19 is installed in the middle of the isolation plate 11 on the other side. A first rotating sealing ring 101 sealing the bottom of the indexing plate is installed on the top of the divider body 10. The two input shafts 13 are sealed with second rotating sealing rings 102 on both sides of the divider body 10. The divider body 10 has an inner cavity 103 close to the indexing plate and the conjugate cam. The liquid inlet component 17 includes a plurality of first through holes 171 that are opened laterally at one end of the divider body 10 and connected to the inner cavity 103. The outer cover of the first through holes 171 is fitted with the same number of first guide tubes 172. The pump housing 162 has a liquid inlet 173 at one end. The liquid inlet 173 connects to all the first guide tubes 172. The components are connected by an inlet pipe 174; the outlet component 18 includes a plurality of second through holes 181 vertically opened on one side of the divider body 10 and connected to the inner cavity 103. The outer cover of the second through holes 181 is equipped with the same number of second guide pipes 182 that penetrate the isolation plate 11. The other end of the pump housing 162 is provided with an outlet 183. The outlet 183 and all the second guide pipes 182 are connected by an outlet pipe 184. The second guide pipes 182 and the outlet pipes 184 have multiple bends.

[0027] In this embodiment, the internal structure of the divider body 10 is a conventional combination of an indexing plate and a conjugate cam, which will not be elaborated here. The lubricating oil inside the divider body 10 is a low-viscosity 0W30 type machine oil, which facilitates flow and heat dissipation due to its low viscosity. Due to the design of the inner cavity 103 close to the indexing plate and the conjugate cam, when the divider body 10 is in operation, the lubricating oil flows from multiple second through holes 181 into the second guide pipe 182 and the outlet pipe 184 into the pump housing 162 under the rotation of the indexing plate. Driven by the pumping component 16, it re-enters the conjugate cam in the inner cavity 103 through the inlet pipe 174, the first guide pipe 172 and the first through hole 171, and the heat is circulated out for heat dissipation through the lubricating oil.

[0028] Please refer to the attached document carefully. Figure 1 , 2 As shown in Figures 3 and 5, the drive component 15 includes a first gear 151 sleeved on the input shaft 13, and a second gear 152 sleeved on the output shaft 14 on the same side. The first gear 151 and the second gear 152 are connected by a toothed belt 153. The pump component 16 includes an impeller 161 sleeved on the input shaft 13. A pump housing 162 mounted on the isolation plate 11 is sleeved on the outside of the impeller 161. A third rotating seal ring 163 is installed at the connection between the input shaft 13 and the pump housing 162. The cooling fan 19 is vertically mounted on the isolation plate 11. The cooling fan 19 has a driven gear 191 with fixedly connected fan blades near the output shaft 14 on the same side. A drive gear 192 that meshes with the driven gear 191 is sleeved at one end of the output shaft 14 on the same side.

[0029] As described above, when the dual-output shaft motor 12 starts, the output shaft 14 on one side drives the input shaft 13 on the same side to rotate through the second gear 152, the toothed belt 153, and the first gear 151, thereby driving the divider body 10 to operate. At the same time, the input shaft 13 on the other side also rotates, driving the impeller 161 to rotate inside the pump housing 162, achieving the pumping effect. During this process, the third rotating seal ring 163 prevents leakage from the pump housing 162. The multi-layer bends of the second guide pipe 182 and the outlet pipe 184 increase their effective heat dissipation area, while the effective heat dissipation area is exposed to the cooling fan 19. On the other side, the number of gears on the drive gear 192 is much greater than the number of gears on the driven gear 191. During startup, the output shaft 14 on the other side of the dual-output shaft motor 12 drives the driven gear 191 to rotate through the drive gear 192, which in turn drives the cooling fan 19 to rotate at high speed, greatly improving the heat dissipation efficiency. At the same time, the output angular velocity of the dual-output shaft motor 12, the speed of the cooling fan 19, the speed of the impeller 161, and the speed of the conjugate cam are directly proportional to each other. The faster the speed of the conjugate cam, the faster the heat is generated, and the higher the corresponding heat dissipation efficiency, thus adapting to the heat dissipation requirements of the divider body 10 during operation.

[0030] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
