[0052] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0053] like Figure 1-3 As shown, a pipe cooling device comprises:

[0054] A cooling water tank 100, wherein a pipe outlet is provided on the cooling water tank 100;

[0055] A vacuum cooling box 200, which is installed at one end of the cooling water tank 100 away from the pipe outlet;

[0056] A weak vacuum chamber is provided in the vacuum cooling box 200, the weak vacuum chamber is connected to the cooling water tank 100, and a pipe inlet is provided on the weak vacuum chamber;

[0057] The pipe conveying mechanism is arranged in the cooling water tank 100 and the vacuum cooling box 200;

[0058] The pipe conveying mechanism includes three sets of roller groups 300 arranged in parallel;

[0059] The roller assembly 300 is suitable for conveying the pipe to move between the cooling water tank 100 and the vacuum cooling box 200;

[0060] The pipe reciprocating mechanism is installed in the cooling water tank 100 and the vacuum cooling box 200;

[0061] The pipe reciprocating mechanism is suitable for driving the pipe to switch to the roller groups 300 in different rows.

[0062] In this embodiment, if Figure 2-3 As shown, the pipe first enters the vacuum cooling box 200 from the pipe inlet of the weak vacuum chamber, and the pipe is transported to the cooling water trough 100 under the guidance of the roller group 300 of the pipe conveying mechanism, and then moves to the pipe reciprocating mechanism near the pipe outlet. Then, the pipe is brought to another roller group 300 moving toward the pipe inlet by the pipe reciprocating mechanism, and the pipe is transported to the vacuum cooling box 200 by the roller group 300. When it reaches the pipe reciprocating mechanism near the pipe inlet, the pipe is again brought to another roller group 300 moving toward the pipe outlet by the pipe reciprocating mechanism, and enters the cooling water trough 100 and finally goes out from the pipe outlet of the cooling water trough 100. This continuous process allows the pipe to move back and forth in the cooling water trough 100 and the vacuum cooling box 200, so that the pipe is cooled multiple times in a length of the cooling water trough 100, thereby increasing the effective cooling distance and improving the pipe production speed. In some embodiments, the number of roller groups 300 is not limited to three groups and can be set according to specific needs.

[0063] Specifically, Figure 1-2 As shown, the vacuum cooling box 200 is also connected to a vacuum pump 210 and a circulating water pump 220;

[0064] The vacuum pump 210 is connected to the weak vacuum chamber through a pipeline and is suitable for evacuating the weak vacuum chamber;

[0065] The circulating water pump 220 is also connected to the weak vacuum chamber through a pipeline and is suitable for circulating the cooling water in the weak vacuum chamber.

[0066] In this embodiment, if Figure 1As shown, the vacuum pump 210 is connected to the inside of the weak vacuum chamber through a pipeline, and can evacuate the weak vacuum chamber to reach a set negative pressure range; the circulating water pump 220 is also connected to the inside of the weak vacuum chamber through a pipeline, and can circulate and suck and discharge the cooling water in the weak vacuum chamber, so that the cooling water flows and circulates in the weak vacuum chamber to fully cool the pipe. During operation, the vacuum pump 210 and the circulating water pump 220 are started synchronously, the vacuum pump 210 evacuates the weak vacuum chamber, and the circulating water pump 220 allows the cooling water to flow and circulate therein. The cooperation of the two can speed up the circulation speed of the cooling water and improve the cooling efficiency. At the same time, the vacuum environment also reduces the boiling point of the cooling water and enhances its cooling capacity, thereby achieving rapid and efficient cooling of the pipe.

[0067] Specifically, Figure 1-2 As shown, the cooling water tank 100 further includes a circulating water supply component, which is suitable for circulating and replenishing the cooling water in the cooling water tank 100;

[0068] The circulating water supply component can be structured as follows:

[0069] A water storage tank 110, wherein cooling water is stored in the water storage tank 110;

[0070] A water supply pump is connected to the water storage tank 110 and the cooling water tank 100 through pipelines. The water supply pump is suitable for replenishing cooling water into the cooling water tank 100 through the water storage tank 110.

[0071] In this embodiment, if Figure 1-2As shown, the water tank 110 stores cooling water for replenishment. During operation, the water supply pump is automatically or manually started to draw cooling water from the water tank 110 and replenish it into the cooling water tank 100 through the pipeline to ensure that the cooling water in the cooling water tank 100 is sufficient. The start of the water supply pump can be automatically controlled according to the level of the cooling water in the cooling water tank 100, or it can be manually controlled. When the cooling water level drops to the set low limit, the water supply pump automatically starts to replenish water to the cooling water tank 100; when the cooling water level rises to the set high limit, the water supply pump automatically stops. Stop water replenishment, which can ensure the recycling of cooling water and avoid waste of water resources. The cooling water tank 100 also includes inlet and outlet components, which are composed of inlet components and outlet components, and are mainly used for the entry of low-temperature water and the discharge of high-temperature water when the cooling water tank 100 is working. The inlet components mainly include inlet solenoid valves, inlet pipes, etc., and the cooling water is transported from the water tank into the cooling water tank 100 through the inlet pipe for cooling circulation; the outlet components mainly include overflow holes, heat exchangers, etc. The high-temperature cooling water in the cooling water tank 100 flows into another water storage tank 110 through the overflow holes, and returns to the water storage tank 110 through the pipeline after the heat exchange is completed. The setting of the inlet and outlet components can realize the recycling of cooling water, reduce operating costs, and facilitate the monitoring and adjustment of the cooling water temperature, thereby ensuring that a stable cooling environment is provided inside the cooling water tank 100.

[0072] Specifically, Figure 1-2 As shown, the pipe cooling device further includes a frame 400, and the cooling water tank 100 and the vacuum cooling box 200 are both fixedly mounted on the frame 400;

[0073] A rack moving mechanism is also provided between the cooling water tank 100 and the vacuum cooling box 200 and the rack 400, and the rack moving mechanism is suitable for adjusting the axis of the pipe inlet of the vacuum cooling box 200 to be aligned with the axis of the center of the pipe main machine.

[0074] In this embodiment, if Figure 1-2 As shown, the vacuum cooling box 200 can be fixedly mounted on the frame 400 by fasteners such as bolts. In order to allow the pipe to enter the cooling water trough 100 smoothly and unimpeded from the vacuum cooling box 200, a frame moving mechanism is also provided between the cooling water trough 100 and the vacuum cooling box 200 and the frame 400. The frame moving mechanism can move the frame 400 in a certain direction to adjust the central axis of the pipe inlet of the vacuum cooling box 200 to be aligned with the central axis of the pipe host.

[0075] Specifically, Figure 1 As shown, the rack moving mechanism can be structured as follows:

[0076] Guide rail 410;

[0077] Roller 420, roller 420 is mounted on the frame 400, and roller 420 is slidably matched with guide rail 410;

[0078] The frame 400 is adapted to slide along the guide rail 410 via the rollers 420 .

[0079] In this embodiment, if Figure 1 As shown, the rack moving mechanism adopts the sliding cooperation structure of the roller 420 and the guide rail 410 on the ground to realize the movement of the rack 400. The guide rail 410 is pre-installed on the ground, and its axial direction is consistent with the direction in which the rack 400 needs to move. The roller 420 is installed at the bottom of the rack 400 and realizes sliding cooperation with the ground guide rail 410. When in use, the rack 400 is pushed by an external force, and the roller 420 will roll along the guide rail 410, driving the rack 400 to move to the set position as a whole. The guide rail 410 plays a role of guiding and positioning, so that the moving direction and distance of the rack 400 can be accurately controlled. The rack moving mechanism is simple and reliable, and the fine adjustment of the rack 400 can be achieved through simple push-pull operations.

[0080] Specifically, Figure 1-3 As shown, a height adjustment mechanism 450 is further provided between the cooling water tank 100 and the rack 400. The height adjustment mechanism 450 may be of the following structure:

[0081] A lead screw support, the lead screw support is fixed on the frame 400;

[0082] An adjusting screw, wherein the adjusting screw is arranged on a screw support;

[0083] A nut seat, the nut seat is fixed to the bottom of the cooling water tank 100;

[0084] The adjusting screw is suitable for rotating through the nut seat to drive the adjusting screw and the cooling water tank 100 to rise and fall in height, so as to adjust the relative position between the cooling water tank 100 and the vacuum cooling box 200.

[0085] In this embodiment, if Figure 2-3 As shown, in order to accurately adjust the height position of the cooling water tank 100, the adjusting screw is rotated, and the adjusting screw moves axially in the nut seat, driving the cooling water tank 100 to rise and fall as a whole, thereby accurately adjusting the height relationship between the cooling water tank 100 and the vacuum cooling box 200, and achieving accurate alignment of the two. The height adjustment mechanism 450 has a compact structure, and the height of the cooling water tank 100 can be smoothly adjusted through a simple rotation operation, meeting the positioning requirements during installation and commissioning.

[0086] Specifically, Figure 1-3 As shown, the pipe reciprocating mechanism can be structured as follows:

[0087] An active transmission component 500 is installed in the cooling water tank 100 and is disposed close to the pipe outlet;

[0088] A driven traction component 510, which is installed in the vacuum cooling box 200 and is disposed close to the pipe inlet;

[0089] The active transmission component 500 is adapted to change the moving direction of the tube to the roller group 300 in the adjacent row when the tube on the roller group 300 moves close to the tube outlet;

[0090] The driven traction component 510 is adapted to cooperate with the active transmission component 500 to change the moving direction of the tube to the roller set 300 in the adjacent row when the tube approaches the tube entrance.

[0091] In this embodiment, if Figure 1-3 As shown, the friction between the active transmission component 500 and the outer wall of the pipe is used to actively change the movement direction of the pipe on the roller group 300, and then the pipe is turned again by cooperating with the active transmission component 500 in the driven traction component 510 to realize the cyclic movement of the pipe between the cooling water tank 100 and the vacuum cooling box 200.

[0092] Specifically, Figure 2-3 As shown, the active transmission component 500 may have the following structure:

[0093] A driving assembly, the driving assembly is installed in the cooling water tank 100;

[0094] A driving roller connected to the driving assembly;

[0095] The driving roller is suitable for being driven by the driving assembly, contacting the outer circumferential surface of the pipe, and driving the pipe to surround the driving roller, thereby changing the movement direction of the pipe on the roller assembly 300.

[0096] In this embodiment, if Figure 1-3 As shown, the driving assembly in the active transmission component 500 can specifically be a driving motor and a reducer. The driving motor drives the driving roller to rotate through the reducer. The outer cylindrical surface of the driving roller is in close contact with the outer wall of the pipe. When the driving roller rotates, the friction force drives the pipe to move in a circular direction, thereby changing the movement direction of the pipe between the roller groups 300. For example, when the pipe is about to move from the roller group 300 at the pipe entrance to the pipe exit direction, the driving roller 503 rotates to drive the pipe to move away from the roller group 300 in the pipe exit direction.

[0097] Specifically, Figure 1-3 As shown, the driven traction component 510 may have the following structure:

[0098] A driven steering wheel, the driven steering wheel is rotatably mounted in the vacuum cooling box 200;

[0099] When the pipe driven by the active transmission component 500 moves to the position of the driven steering wheel, the pipe contacts the driven steering wheel and drives the driven steering wheel to rotate. The driven steering wheel is suitable for changing the movement direction of the pipe to the next roller group 300.

[0100] In this embodiment, if Figure 2-3 As shown, the driven steering wheel may specifically include a steering wheel and a steering wheel bearing. The steering wheel may be rotatably installed around the steering wheel bearing in the vacuum cooling box 200. When the pipe driven by the driving assembly moves to the steering wheel position, the outer wall of the pipe contacts the steering wheel and drives the steering wheel to rotate. Through the traction of the steering wheel, the movement direction of the pipe is changed, and the pipe is guided to the next roller group 300 to continue moving, so as to realize the reciprocating movement of the pipe in the cooling water tank 100 and the vacuum cooling box 200, so as to achieve the purpose of sufficient cooling. The setting of the steering wheel can simplify the structure, and its rotation and guiding function can change the movement direction of the pipe relatively smoothly, which is beneficial to reduce the stress of the pipe and ensure its outer diameter size and wall thickness accuracy.

[0101] Specifically, Figure 1 As shown, the rotation speed of the active transmission component 500 is the same as the moving speed of the pipe entering from the pipe inlet.

[0102] In this embodiment, if Figure 1-2As shown, in order to avoid the problem of uneven tension in the pipe during the cyclic motion, the rotation speed of the active transmission component 500 needs to be synchronized with the moving speed of the pipe entering from the pipe inlet. If the rotation speed of the drive component is not synchronized with the moving speed of the pipe, the pipes on both sides of the active transmission component 500 will have inconsistent tension. The pipe on the side with less tension will float in the cooling water, affecting normal movement; the pipe on the side with greater tension will be stretched and deformed, affecting the dimensional accuracy of the pipe. In order to solve this problem, the rotation speed of the drive component can be detected and controlled by a frequency conversion speed regulation device to keep the rotation speed of the drive component consistent with the entering movement speed of the pipe. This can effectively reduce the change in force on the pipe during the cyclic motion and ensure the dimensional accuracy of the outer diameter and wall thickness of the pipe. The main pipes of the utility model are small precision tubes such as medical tubes. In the precision tube production line, considering that the outer diameter of this type of pipe is generally small, generally around 2 in diameter 0mm or less, the production line speed is relatively fast, generally more than 50 meters per minute, and the site of manufacturers of precision small tubes such as medical tubes is not very long, so the site issue is always the primary consideration. This embodiment realizes more than 100 cooling of the pipe in a cooling water trough of a certain length, increases the effective cooling distance, and improves the production speed of the product. Compared with the traditional overall occupied length of 14 meters, this embodiment only needs 6.7 meters, saving the length of 2 cooling water troughs 100, greatly shortening the site occupied distance, and saving the equipment manufacturing cost. The cooling water trough 100 generally adopts immersion cooling.

[0103] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
