DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-3 This application is described in further detail.

[0035] The embodiment of the present application discloses a vacuum cooling device for a medical cannula.

[0036] Reference Figure 1 and Figure 2 The vacuum cooling device includes a base 1, a cooling box 2, an auxiliary component 3 and an air pump 4. The base 1 is arranged in a rectangular box shape, and the cooling box 2 is installed on the upper side of the base 1. The cooling box 2 is also arranged in a rectangular box shape, and a rectangular cooling water trough 21 is provided on the upper side of the cooling box 2. The cooling water trough 21 is used to contain cooling water. At the same time, the cooling box 2 is provided with a feed hole 22 and a discharge hole 23 at both ends of the cooling water trough 21. The feed hole 22 is aligned with the discharge end of the extrusion molding machine (not shown in the figure) to realize the feeding of the sleeve. The discharge hole 23 is located in the same straight line as the feed hole 22 to discharge the cooled sleeve.

[0037] The auxiliary component 3 includes a cover plate 31 and a vent pipe 32. The cover plate 31 is rotatably connected to the upper side of the cooling box 2. The cover plate 31 is rotated to move the cover plate 31 away from the cooling water tank 21 to open the cooling water tank 21, or the cover plate 31 is covered on the cooling water tank 21 to close the cooling water tank 21. The vent pipe 32 is fixedly connected to the upper side of the cover plate 31. The air pump 4 is fixedly connected to the base 1, and the air pump 4 is connected to the upper end of the vent pipe 32 through a bellows (not shown in the figure).

[0038] In actual application, cooling water is added to the cooling water tank 21. The way of adding water can be to open the cover plate 31 and add it directly to the cooling water tank 21, or to pump the cooling water into the cooling water tank 21 through a water pump, which is not limited in this application. By rotating the cover plate 31, the cover plate 31 is covered on the cooling water tank 21, and the vacuum pump 4 is turned on at the same time. The vacuum pump 4 evacuates air from the cooling water tank 21 through the vent pipe 32, so that the cooling water tank 21 is in a vacuum state. At this time, the extruded sleeve enters the cooling water tank 21 from the feed hole 22 and is cooled under the action of the cooling water. After cooling, it leaves the cooling water tank 21 from the discharge hole 23. In this process, the sleeve is cooled in a vacuum state, which can ensure that the air content in each part of the sleeve is consistent as much as possible, and avoid the problem of flattening or irregular shape as much as possible, thereby improving the production quality of the sleeve.

[0039] In some embodiments, the cover plate 31 is made of glass, that is, the cover plate 31 is relatively transparent, and the internal conditions of the cooling water tank 21 can be observed through the cover plate 31, thereby facilitating the observation of the cooling work of the sleeve.

[0040] Reference Figure 2 and Figure 3 In some embodiments, the auxiliary component 3 further includes a sealing rubber ring 33, which is arranged in a rectangular ring shape and is fixedly connected to the upper side of the cooling box 2, so that the cover plate 31 abuts against the upper side of the sealing rubber ring 33 to ensure the sealing between the cover plate 31 and the cooling box 2, thereby ensuring that the cooling water tank 21 is stably in a vacuum state as much as possible to improve the production quality of the sleeve. At the same time, when the cover plate 31 abuts against the sealing rubber ring 33, there is a gap between the cover plate 31 and the cooling box 2, so as to facilitate the rotation of the cover plate 31 covering the cooling water tank 21.

[0041] In some embodiments, the auxiliary component 3 further includes a support ring 34, which is fixedly connected to the upper side of the cooling box 2, and is arranged along the circumference of the sealing rubber ring 33 and is located on the inner side of the sealing rubber ring 33, and the support ring 34 is lower than the sealing rubber ring 33. The sealing rubber ring 33 is fixedly connected to the support ring 34 by bolts and nuts to achieve the fixation and support of the sealing rubber ring 33, and to avoid excessive deformation of the sealing rubber ring 33 as much as possible, thereby further ensuring that the cooling water tank 21 is stably in a vacuum state, and also facilitating the installation and removal of the sealing rubber ring 33.

[0042] Reference Figure 1 and Figure 2 In some embodiments, the auxiliary component 3 also includes a pressure gauge 35, which is fixedly connected to the upper side of the cover plate 31 and extends to the lower side of the cover plate 31 to detect the air pressure in the cooling water tank 21, so as to understand the air pressure in the cooling water tank 21 and ensure that the cooling water tank 21 is in a vacuum state.

[0043] In some embodiments, the auxiliary component 3 further includes an overflow pipe 36, which is fixedly connected to the bottom wall of the cooling water tank 21, and the lower end of the overflow pipe 36 extends to the bottom of the cooling box 2, so that the overflow pipe 36 is connected to the outside of the cooling box 2. When the cooling water in the cooling water tank 21 reaches a certain height, the cooling water flows out of the cooling water tank 21 from the overflow pipe 36, and the amount of cooling water is reduced under the condition that the sleeve can be cooled normally, and the air in the cooling water is prevented from affecting the vacuum state of the cooling water tank 21 as much as possible.

[0044] In some embodiments, the vacuum cooling device also includes a water collecting frame 5, which is fixedly connected to the upper side of the base 1, and the cooling box 2 is fixedly connected to the upper side of the water collecting frame 5, and there is a certain distance between the cooling box 2 and the water collecting frame 5. The cooling water flowing out of the overflow pipe 36 flows into the water collecting frame 5, so that the cooling water can be reused.

[0045] In some embodiments, the auxiliary component 3 also includes a support roller 37, which is rotatably connected to the cooling water trough 21. The support roller 37 is horizontally arranged and the axis of rotation is perpendicular to the length direction of the cooling water trough 21. The sleeve is overlapped on the support roller 37 to support the sleeve, and the support roller 37 rotates during the movement of the sleeve, thereby improving the stability of the movement of the sleeve.

[0046] In some embodiments, the number of the support rollers 37 is two, and the two support rollers 37 are spaced apart along the length direction of the cooling water tank 21 to further improve the stability of the movement of the sleeve.

[0047] In some embodiments, the number of cooling water troughs 21 and auxiliary components 3 are both multiple, and the number of cooling water troughs 21 and auxiliary components 3 is the same, so that each auxiliary component 3 is adapted to each cooling water trough 21. Among them, multiple cooling water troughs 21 are evenly spaced along the length direction of the cooling box 2, and the discharge hole 23 of each cooling water trough 21 is connected with the feed hole 22 of the adjacent cooling water trough 21, so that the sleeve is vacuum cooled multiple times, effectively ensuring that the air content in each part of the sleeve is consistent, effectively avoiding the problem of flattening or irregular shape, thereby further improving the production quality of the sleeve.

[0048] The implementation principle of this embodiment is as follows: in actual application, cooling water is added to the cooling water tank 21. The way of adding water can be to open the cover plate 31 and add it directly to the cooling water tank 21, or to pump the cooling water into the cooling water tank 21 through a water pump, which is not limited in this application. By rotating the cover plate 31, the cover plate 31 is covered on the cooling water tank 21, and the vacuum pump 4 is turned on at the same time. The vacuum pump 4 pumps air out of the cooling water tank 21 through the vent pipe 32, so that the cooling water tank 21 is in a vacuum state. At this time, the extruded sleeve enters the cooling water tank 21 from the feed hole 22 and is cooled under the action of the cooling water. After cooling, it leaves the cooling water tank 21 from the discharge hole 23. In this process, the sleeve is cooled in a vacuum state, which can ensure that the air content in each part of the sleeve is consistent as much as possible, and avoid the problem of flattening or irregular shape as much as possible, thereby improving the production quality of the sleeve.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
