Description

Technical Field

[0001] The present invention relates to the technical field of cooling cycles, and more specifically, to a cooling cycle mechanism for extruded water pipe forming. Background Art

[0002] Cooling cycle refers to a process in which, through a certain device or system, a liquid or gas is used as a cooling medium to repeatedly exchange heat to keep the system temperature within a set range. Cooling cycles are widely used in various industrial, mechanical, electronic, and automotive fields to ensure that equipment, machines, or systems do not overheat during operation and prevent failures or damages caused by excessive temperature.

[0003] According to a publicly disclosed purification device for external circulation cooling water in extrusion (publication number: CN211111460U), it includes three barrels. The three barrels are placed on the same bottom plate. The lower end of the barrel is threadedly connected with a cover body. The upper ends of the three barrels are fixedly connected with water distribution pipes. The upper ends of the three water distribution pipes are fixedly connected with the same water inlet pipe. The front ends of the three barrels are fixedly communicated with communicating pipes. The front side of the bottom plate is fixedly connected with a water outlet pipe. The three communicating pipes are all communicated with the water outlet pipe. A purification mechanism for purifying water is provided inside the barrel. This invention has a good purification effect on cooling water and can produce while maintaining plastic masterbatch.

[0004] The components such as the barrels and water distribution pipes in the above application cooperate with each other to achieve a better purification effect. However, the above application cannot achieve the effect of cooling cycle. Therefore, we propose a cooling cycle mechanism for extruded water pipe forming.

[0005] Summary of the Invention The present invention proposes a cooling cycle mechanism for extruded water pipe forming, which solves the problem of a cooling cycle mechanism for extruded water pipe forming in the related art.

[0006] According to one aspect, at least one embodiment of the present disclosure provides a cooling cycle mechanism for extruded water pipe forming, including: a base, a bracket fixedly connected to the top of the base, a discharging device fixedly connected to the side of the bracket, a feeding groove opened on the top of the base, a sieve plate fixedly connected to the side of the feeding groove, and a cooling device arranged on the top of the base.

[0007] The cooling device comprises a fixed plate, the bottom of which is fixedly connected to the top of the base, the side of which is fixedly connected to a motor, the output shaft of the motor is fixedly connected to a threaded rod, the circumferential surface of the threaded rod is fixedly connected to a half gear, the top of the base is slidably connected to a rack, one end of the rack is fixedly connected to a striker, the top of the base is fixedly connected to a water pump box A, the top of the water pump box A is fixedly penetrated by a water inlet pipe, one end of the water pump box A is slidably connected to a force rod A, and the other end of the water pump box A is slidably connected to a perforated tube. Through the operation of the water pump box A, liquid flows into the cooling system and takes away the heat after adjustment. The design of the force rod A and the perforated tube can adjust the flow rate and flow of the coolant as needed to cope with different working conditions. The cooling device combines a mechanical transmission system driven by a motor with a liquid circulation system, which can effectively take away the heat during the forming of the water pipe while ensuring the precise adjustment of the system, so that the water pipe can be formed quickly, improve work efficiency, and increase production. .

[0008] The half gear is meshed with the rack, and a leather plug is inserted at the top of the water inlet pipe. The meshing of the half gear and the rack and the design of the leather plug work together to make the cooling system more efficient and flexible, and can adapt to different operating conditions while maintaining sealing and avoiding waste or leakage of coolant. The meshing between the half gear and the rack enables the mechanical system to achieve the conversion of rotational motion to linear motion through the drive of the motor.

[0009] For example, in a cooling circulation mechanism for extruded water pipe forming provided by at least one embodiment of the present disclosure, one end of the stress-bearing rod A is located on the displacement track of the impact rod. The linkage design of the stress-bearing rod A and the impact rod provides precise control capability for the cooling device, helping the system to automatically adjust the fluid flow and working state, thereby enhancing the efficiency and stability of the system.

[0010] The circumferential surface of the force-bearing rod A is fixedly connected with a return spring A, and one end of the return spring A is fixedly connected to one end of the water pump box A. The return spring A is connected to the water pump box A, and is mainly used to provide restoring force, shock absorption, and stable operation, to ensure that the equipment can return to its original position and maintain its normal function when subjected to external interference.

[0011] One end of the water pump box A is fixedly connected to a spring, and one end of the spring is located on the displacement track of the striker. The spring is designed to push the rack to reset when the rack is not subjected to the force brought by the rotation of the half gear, so that the striker can repeatedly push the force-bearing rod A According to another aspect, at least one embodiment of the present disclosure further provides a cooling circulation mechanism problem for extrusion water pipe forming, including: a circulation device is arranged on the circumferential surface of the threaded rod, the circulation device includes a threaded sleeve, the threaded sleeve is threadedly connected to the circumferential surface of the threaded rod, a limiting rod is fixedly connected to the side surface of the fixed plate, an L-shaped push rod is fixedly connected to the circumferential surface of the threaded sleeve, a placement groove is formed at the top of the base, a water pump box B is fixedly connected to the top of the placement groove, a force-receiving rod B is piston-slidingly connected to one end of the water pump box B, a water inlet pipe is fixedly connected to the other end of the water pump box B, a diversion plate is fixedly connected to the top of the water inlet pipe, and a water delivery pipe is piston-slidingly connected to one end of the water pump box B. The design of this device is to make the water sprayed by the water pump box A after cooling flow into the water pump box B, and then the water pump box B conveys the collected water to the water pump box A again for reuse, so that the water resources can be recycled multiple times, improving the utilization rate of resources and reducing the waste of resources.

[0012] For example, in a cooling circulation mechanism for extrusion water pipe forming provided by at least one embodiment of the present disclosure, it further includes: the other end of the water delivery pipe is fixedly connected to the bottom of the water pump box A, a rotating shaft is rotatably connected to the inner side surface of one end of the water delivery pipe, a closing plate is fixedly connected to the circumferential surface of the rotating shaft, a top rod is fixedly connected to the inner side surface of the water delivery pipe, and one end of the top rod is located on the displacement track of the closing plate. Through the connection between the top rod and the closing plate, it is ensured that the closing plate can move along a predetermined track, thereby adjusting and controlling the opening and closing of the water flow.

[0013] A return spring B is fixedly connected to the circumferential surface of the force-receiving rod B, one end of the force-receiving rod B is located on the displacement track of the L-shaped push rod, a sliding groove is formed at the top of the base, the L-shaped push rod is slidably connected to the sliding groove, and the circumferential surface of the threaded sleeve is slidably connected to the circumferential surface of the limiting rod. The function of the return spring B is to provide a restoring force to ensure that the system can reset after being acted on by an external force; the combination of the L-shaped push rod and the sliding groove ensures that the L-shaped push rod moves along a certain track; the sliding connection between the threaded sleeve and the limiting rod provides an adjustment and limiting function. The design purpose of the entire system is to ensure the precise operation and automatic reset function of the mechanical equipment.

[0014] A screen plate descaling device is arranged on the circumferential surface of the threaded rod. The screen plate descaling device includes a sliding sleeve. The circumferential surface of the sliding sleeve is threadedly connected to the circumferential surface of the threaded rod. A connecting rod is fixedly connected to the circumferential surface of the sliding sleeve. One end of the connecting rod is fixedly connected to a brush rod, and a brush is fixedly connected to the bottom of the brush rod. The function of this device is to drive the sliding sleeve to move axially along the threaded rod through the rotation of the threaded rod, thereby driving the connecting rod and the brush rod. The brush at the bottom of the brush rod cleans the screen plate to remove dirt or deposits on it. This structure is mainly used to realize the automatic descaling function of the screen plate, ensure that the screen plate can work effectively for a long time, and avoid blockage or fouling affecting the screening effect.

[0015] The top of the screen plate is located on the displacement track of the brush. The circumferential surface of the sliding sleeve is slidably connected to the circumferential surface of the limiting rod. This design ensures precise control during the cleaning process, avoids abnormal movement of the equipment, and improves the cleaning effect.

[0016] The working principle and beneficial effects of the present invention are as follows: 1. In the present invention, through the cooperation of components such as a motor, a threaded rod, a semi-gear, a water pump box A, and a rack, when the motor is started, the motor drives the threaded rod to rotate. The rotation of the threaded rod drives the semi-gear to rotate. The rotation of the semi-gear drives the rack to move horizontally. The horizontal movement of the rack drives the impact rod to move horizontally. The horizontal movement of the impact rod pushes the force-receiving rod A. The force-receiving rod A pushes the coolant in the water pump box A to be ejected through the hole pipe to quickly cool the surface of the water pipe, thereby achieving the effect of rapid cooling and rapid forming of the water pipe, improving work efficiency and increasing output.

[0017] 2. In the present invention, through the cooperation of components such as a motor, a threaded rod, a threaded sleeve, a limiting rod, and a water pump box B, when the motor is started, the motor drives the threaded rod to rotate. The rotation of the threaded rod drives the threaded sleeve to move horizontally under the restriction of the limiting rod. The horizontal movement of the threaded sleeve drives the L-shaped impact rod to move horizontally. The coolant ejected from the water pump box A falls onto the drainage plate through the screen plate and flows into the water pump box B through the drainage plate. The L-shaped impact rod pushes the force-receiving rod B. The force-receiving rod B moves the piston to push the water collected in the water pump box B through the water delivery pipe. The water flow pushes the closing plate, and the closing plate rotates and opens through the rotating shaft, allowing the water to flow into the water pump box A, thereby realizing the circulation of the coolant, enabling the water resource to be recycled multiple times, improving the utilization rate of resources, and reducing the waste of resources.

[0018] 3. In the present invention, through the cooperation of components such as a motor, a threaded rod, a sliding sleeve, and a brush rod, when the motor is started, the motor drives the threaded rod to rotate. The rotation of the threaded rod drives the sliding sleeve to move horizontally under the restriction of the limiting rod. The horizontal movement of the sliding sleeve drives the connecting rod to move horizontally. The horizontal movement of the connecting rod drives the brush rod to move horizontally. The horizontal movement of the brush rod drives the brush to move horizontally, and the brush moves horizontally to remove dirt from the sieve plate, thereby ensuring that the sieve plate can work effectively for a long time and avoiding blockage or fouling from affecting the screening effect.

[0025] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0026] Embodiment 1 As Figures 1 to 7 shown, it shows a cooling circulation mechanism for extrusion water pipe forming in an embodiment of the present disclosure, including: a base 1, a bracket 2 is fixedly connected to the top of the base 1, a discharging device 3 is fixedly connected to the side of the bracket 2, a feeding groove 5 is opened on the top of the base 1, a sieve plate 7 is fixedly connected to the side of the feeding groove 5, and a cooling device 4 is arranged on the top of the base 1; The cooling device 4 includes a fixed plate 41, the bottom of the fixed plate 41 is fixedly connected to the top of the base 1, the side of the fixed plate 41 is fixedly connected to a motor 42, the output shaft of the motor 42 is fixedly connected to a threaded rod 43, the circumferential surface of the threaded rod 43 is fixedly connected to a half gear 44, the top of the base 1 is slidably connected to a rack 45, one end of the rack 45 is fixedly connected to a striker 46, the top of the base 1 is fixedly connected to a water pump box A47, the top of the water pump box A47 is fixedly penetrated by a water inlet pipe 48, one end of the water pump box A47 is slidably connected to a force rod A49, and the other end of the water pump box A47 is slidably connected to a perforated tube 410. Through the operation of the water pump box A47, liquid flows into the cooling system and takes away heat after adjustment. The design of the stress-bearing rod A49 and the hole tube 410 can adjust the flow rate and flow of the coolant as needed to cope with different working conditions. The cooling device 4 is combined with a mechanical transmission system driven by a motor 42 and a liquid circulation system. While ensuring precise adjustment of the system, it can effectively take away the heat during the forming of the water pipe, so that the water pipe can be quickly formed, thereby improving work efficiency and increasing production.

[0027] In some examples, the half gear 44 is meshed with the rack 45, and a leather plug 411 is inserted into the top of the water inlet pipe 48. The meshing of the half gear 44 and the rack 45 and the design of the leather plug 411 work together to make the cooling system more efficient and flexible, and can adapt to different operating conditions while maintaining sealing and avoiding waste or leakage of coolant. The meshing between the half gear 44 and the rack 45 enables the mechanical system to achieve the conversion of rotational motion to linear motion through the drive of the motor 42.

[0028] One end of the stress rod A49 is located on the displacement track of the striker 46. The linkage design of the stress rod A49 and the striker 46 provides precise control capability for the cooling device 4, helping the system to automatically adjust the fluid flow and working state, thereby enhancing the efficiency and stability of the system.

[0029] The circumferential surface of the force-bearing rod A49 is fixedly connected with a return spring A412, and one end of the return spring A412 is fixedly connected to one end of the water pump box A47. The return spring A412 is connected to the water pump box A47, and is mainly used to provide restoring force, shock absorption, and stable operation, ensuring that the equipment can return to its original position and maintain its normal function when subjected to external interference.

[0030] One end of the water pump box A47 is fixedly connected with a spring 413, and one end of the spring 413 is located on the displacement track of the striker 46. The design of the spring 413 is to push the rack 45 to reset when the rack 45 is not subjected to the force brought by the rotation of the half gear 44, so that the striker 46 can repeatedly push the force-bearing rod A49.

[0031] For example, Figures 1 to 7As shown, the starting motor 42 is started, and the motor 42 drives the threaded rod 43 to rotate. The rotation of the threaded rod 43 drives the half gear 44 to rotate. The rotation of the half gear 44 drives the rack 45 to move horizontally. The horizontal movement of the rack 45 drives the impact rod 46 to move horizontally. The horizontal movement of the impact rod 46 pushes the force-bearing rod A49. The force-bearing rod A49 pushes the coolant in the water pump box A47 to spray out through the hole pipe 410, quickly cooling the surface of the water pipe. When the water pump box A47 is operating, the closing plate 611 at one end of the water delivery pipe 69 is in a closed state under the action of the ejector rod 612, and the coolant cannot flow out of the water delivery pipe 69. When the force on the force-bearing rod A49 disappears, the return spring A412 drives the force-bearing rod A49 to return horizontally through its own elastic force. When the part of the half gear 44 without teeth rotates to the position of the rack 45, the spring 413 pushes the impact rod 46, and the impact rod 46 drives the rack 45 to return horizontally.

[0032] Embodiment 2 As Figures 1 to 7 shown, it shows a cooling circulation mechanism for extrusion water pipe forming in another embodiment of the present disclosure. Its technical solution is generally the same as that of Embodiment 1, so only the differences will be described in detail, including: a circulation device 6 is arranged on the circumferential surface of the threaded rod 43. The circulation device 6 includes a threaded sleeve 61. The threaded sleeve 61 is threadedly connected to the circumferential surface of the threaded rod 43. A limiting rod 62 is fixedly connected to the side surface of the fixing plate 41. An L-shaped push rod 63 is fixedly connected to the circumferential surface of the threaded sleeve 61. A placement groove 64 is opened at the top of the base 1. A water pump box B65 is fixedly connected to the top of the placement groove 64. A force-bearing rod B66 is slidably connected to one end of the water pump box B65 by a piston. A water inlet pipe 67 is fixedly connected to the other end of the water pump box B65. A diversion plate 68 is fixedly connected to the top of the water inlet pipe 67. A water delivery pipe 69 is slidably connected to one end of the water pump box B65 by a piston. The design of this device is to make the water sprayed by the water pump box A47 after cooling flow into the water pump box B65, and then the water collected by the water pump box B65 is transported to the water pump box A47 again for reuse, so that the water resources can be recycled multiple times, improving the utilization rate of resources and reducing waste of resources.

[0033] In some examples, it further includes: the other end of the water delivery pipe 69 is fixedly connected to the bottom of the water pump box A47. A rotating shaft 610 is rotatably connected to the inner side surface of one end of the water delivery pipe 69. A closing plate 611 is fixedly connected to the circumferential surface of the rotating shaft 610. A ejector rod 612 is fixedly connected to the inner side surface of the water delivery pipe 69. One end of the ejector rod 612 is located on the displacement track of the closing plate 611. Through the connection between the ejector rod 612 and the closing plate 611, it is ensured that the closing plate 611 can move along a predetermined track, thereby adjusting and controlling the opening and closing of the water flow.

[0034] A return spring B613 is fixedly connected to the circumferential surface of the force-bearing rod B66. One end of the force-bearing rod B66 is located on the displacement trajectory of the L-shaped push rod 63. A sliding groove 614 is formed at the top of the base 1. The L-shaped push rod 63 is slidably connected to the sliding groove 614. The circumferential surface of the threaded sleeve 61 is slidably connected to the circumferential surface of the limiting rod 62. The function of the return spring B613 is to provide a restoring force to ensure that the system can reset after being subjected to an external force. The combination of the L-shaped push rod 63 and the sliding groove 614 ensures that the L-shaped push rod 63 moves along a certain trajectory. The sliding connection between the threaded sleeve 61 and the limiting rod 62 provides an adjustment and limiting function. The design purpose of the entire system is to ensure the precise operation and automatic reset function of the mechanical equipment.

[0035] For example, as Figures 1 to 7 shown, start the motor 42. The motor 42 drives the threaded rod 43 to rotate. The rotation of the threaded rod 43 drives the threaded sleeve 61 to move horizontally under the restriction of the limiting rod 62. The horizontal movement of the threaded sleeve 61 drives the L-shaped push rod 63 to move horizontally. The coolant sprayed by the water pump box A47 falls onto the diversion plate 68 through the sieve plate 7 and flows into the water pump box B65 through the diversion plate 68. The L-shaped push rod 63 pushes the force-bearing rod B66. The piston movement of the force-bearing rod B66 pushes the water collected in the water pump box B65 through the water delivery pipe 69. The water flow pushes the closing plate 611, and the closing plate 611 rotates and opens through the rotating shaft 610, enabling the water to flow into the water pump box A47 for recycling. When the force-bearing rod B66 loses the thrust, the return spring B613 drives the force-bearing rod B66 to reset horizontally through its own elastic force.

[0036] Embodiment 3 As Figures 1 to 7 shown, it shows a cooling circulation mechanism for extruded water pipe forming in another embodiment of the present disclosure. Its technical solution is substantially the same as that of Embodiment 2, so only the differences will be mainly described, including: a sieve plate descaling device 8 is arranged on the circumferential surface of the threaded rod 43. The sieve plate descaling device 8 includes a sliding sleeve 81. The circumferential surface of the sliding sleeve 81 is threadedly connected to the circumferential surface of the threaded rod 43. A connecting rod 82 is fixedly connected to the circumferential surface of the sliding sleeve 81. One end of the connecting rod 82 is fixedly connected to a brush rod 83. A brush 84 is fixedly connected to the bottom of the brush rod 83. The function of this device is to drive the sliding sleeve 81 to move axially along it through the rotation of the threaded rod 43, thereby driving the connecting rod 82 and the brush rod 83. The brush 84 at the bottom of the brush rod 83 cleans the sieve plate 7 to remove dirt or deposits on it. This structure is mainly used to realize the automatic descaling function of the sieve plate 7 to ensure that the sieve plate 7 can work effectively for a long time and avoid blockage or scale accumulation affecting the screening effect.

[0037] In some examples, it further includes: the top of the sieve plate 7 is located on the displacement track of the brush 84, and the circumferential surface of the sliding sleeve 81 is slidably connected to the circumferential surface of the limiting rod 62. This design ensures precise control during the cleaning process, avoids abnormal movement of the device, and improves the cleaning effect.

[0038] For example, as Figures 1 to 7 shown, start the motor 42, the motor 42 drives the threaded rod 43 to rotate, the rotation of the threaded rod 43 drives the sliding sleeve 81 to move horizontally under the restriction of the limiting rod 62, the horizontal movement of the sliding sleeve 81 drives the connecting rod 82 to move horizontally, the horizontal movement of the connecting rod 82 drives the brush rod 83 to move horizontally, the horizontal movement of the brush rod 83 drives the brush 84 to move horizontally, and the horizontal movement of the brush 84 removes dirt from the sieve plate 7.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
