Description

Technical Field

[0001] This utility model relates to a heat shrink tubing shrinkage device, belonging to the field of medical device heat shrink technology. Background Technology

[0002] In the field of medical devices, heat shrink technology is widely used for insulation protection, corrosion prevention, marking, and connection fixing of tubular workpieces. This technology heats materials with heat shrink properties, causing them to shrink radially and thus tightly wrap around the surface of the workpiece. Currently, the traditional manual heat shrink gun method is widely used, but this method requires the operator to manually aim the heat shrink gun at the tubular workpiece for heating. This method is currently inefficient and prone to uneven heating, resulting in the heat shrink sleeve not being able to evenly cover the workpiece. Therefore, there is an urgent need for a heat shrink device that provides uniform heating and high efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a heat shrink tubing shrinking device that can inspect multiple tubular workpieces in a short time while ensuring that the heat shrink tubing can be uniformly heat-shrinked onto the tubular workpieces.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a heat shrink tubing shrinking device, comprising: a large disc, a small disc, and a reducer arranged in parallel and vertically spaced on a platform, wherein the central through hole of the large disc is fitted onto the central shaft of the reducer and connected to the rotating shaft cylinder of the reducer, and the central shaft of the reducer is embedded in the central through hole of the large disc and connected to the central area of ​​the small disc; The reducer mounted on the bracket is connected to a motor at the end away from the large disc. A heating mechanism is provided on the side of the small disc opposite to the large disc. Several circular bolts embedded in the through holes of the large disc are provided at intervals in the edge area of ​​the large disc and around the periphery of the small disc. The circular bolts are located at the front end of the large disc for mounting tubular workpieces. A heat shrink tubing is fitted onto the tubular workpiece. The hot air drying mechanism includes a hot air gun and a conical air duct connected to the air outlet of the hot air gun. A conical air shroud is fitted around the conical air duct. The opening of the conical air shroud is larger than the opening of the conical air duct and is located above the opening of the conical air duct, thereby forming a heat storage cavity between the conical air duct and the conical air shroud.

[0005] The following are further improvements to the above technical solution: 1. In the above scheme, a bearing is provided between the central shaft and the rotating cylinder.

[0006] 2. In the above scheme, two L-shaped brackets are provided at intervals between the side of the hanger opposite to the reducer and the platform.

[0007] 3. In the above scheme, the cone-shaped air duct is duckbill-shaped, and the cone-shaped air hood is duckbill-shaped.

[0008] 4. In the above scheme, the hot air gun is mounted on the side surface of the small disc via a support plate.

[0009] 5. In the above scheme, the opening length of the conical hood is greater than the length of the heat shrink tubing, and the opening width of the conical hood is greater than the diameter of the heat shrink tubing.

[0010] 6. In the above scheme, the opening of the conical hood has a constrained air outlet with one side arranged parallel to the axis of the hot air gun.

[0011] 7. In the above scheme, a CNC operation panel (15) is provided on the stage (1).

[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: 1. This utility model relates to a heat shrink tubing shrinking device, comprising a large disc, a small disc, and a reducer arranged parallel to each other and vertically on a platform. The central through hole of the large disc is fitted onto the central shaft of the reducer and connected to the rotating shaft of the reducer. The central shaft of the reducer is embedded in the central through hole of the large disc and connected to the central area of ​​the small disc. A motor is connected to the end of the reducer mounted on a bracket away from the large disc. A heating mechanism is provided on the side of the small disc opposite to the large disc. Several through holes embedded in the central through hole of the large disc are spaced apart around the periphery of the small disc. The circular pin with holes, located at the front end of the large disc, is used to mount tubular workpieces, which are fitted with heat-shrinkable tubing. The large disc drives the tubular workpieces to rotate circumferentially, while the heating mechanism sequentially heats the heat-shrinkable tubing fitted onto the tubular workpieces. When the heating mechanism heats one tubular workpiece, the large disc stops rotating. At this point, the operator can remove the other heated tubular workpieces and replace them with other tubular workpieces to be heat-shrinked, enabling the heat-shrinkable tubing shrinking device to efficiently inspect multiple tubular workpieces in a short time.

[0013] 2. The heat shrink tubing shrinking device of this utility model includes a heat drying mechanism comprising a hot air gun and a conical air duct connected to the air outlet of the hot air gun. A conical air shroud is fitted around the conical air duct, and the opening of the conical air shroud is larger than the opening of the conical air duct and is located above the opening of the conical air duct, thereby forming a heat storage cavity between the conical air duct and the conical air shroud. By setting the heat storage cavity to store the high-temperature gas blown out by the hot air gun, the temperature difference between the two ends and the center of the heat shrink tubing can be minimized as much as possible, ensuring that the heat shrink tubing can be uniformly heat-shrink onto the tubular workpiece.

Detailed Implementation

[0016] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0017] Example 1: A heat shrink tubing shrinking device includes: a large disc 2, a small disc 3, and a reducer 4 arranged in parallel and vertically spaced on a platform 1. The central through hole 201 of the large disc 2 is fitted onto the central shaft 41 of the reducer 4 and connected to the rotating shaft cylinder 42 of the reducer 4. The central shaft 41 of the reducer 4 is embedded in the central through hole 201 of the large disc and connected to the central area of ​​the small disc 3. The reducer 4 mounted on the bracket 5 is connected to a motor 6 at the end away from the large disc 2. A heating mechanism 9 is provided on the side of the small disc 3 opposite to the large disc 2. Several circular bolts 7 are provided at intervals around the edge of the large disc 2 and around the periphery of the small disc 3. These circular bolts 7 are located at the front end of the large disc 2 for mounting a tubular workpiece 100. A heat shrink tubing 101 is fitted onto this tubular workpiece 100. The hot air drying mechanism 9 includes a hot air gun 10 and a conical air duct 11 connected to the air outlet of the hot air gun 10. A conical air cover 12 is fitted around the conical air duct 11. The opening of the conical air cover 12 is larger than the opening of the conical air duct 11 and is located above the opening of the conical air duct 11, thereby forming a heat storage cavity 13 between the conical air duct 11 and the conical air cover 12.

[0018] A bearing 43 is provided between the central shaft 41 and the rotating cylinder 42.

[0019] The central shaft 41 of the reducer 4 does not rotate, but the rotating shaft 42 of the reducer 4 can rotate.

[0020] The cone-shaped air duct 11 is duckbill-shaped, and the cone-shaped air hood 12 is duckbill-shaped.

[0021] The aforementioned hot air gun 10 is mounted to the side surface of the small disc 3 via a support plate 17.

[0022] The opening length of the conical hood 12 is greater than the length of the heat shrink tubing 101, and the opening width of the conical hood 12 is greater than the diameter of the heat shrink tubing 101.

[0023] A CNC operation panel 15 is provided on the aforementioned platform 1.

[0024] Example 2: A heat shrink tubing shrinking device, comprising: a large disc 2, a small disc 3 and a reducer 4 arranged in parallel and vertically spaced on a platform 1, wherein the central through hole 201 of the large disc 2 is fitted onto the central shaft 41 of the reducer 4 and connected to the rotating shaft cylinder 42 of the reducer 4, and the central shaft 41 of the reducer 4 is embedded in the central through hole 201 of the large disc and connected to the central area of ​​the small disc 3; The reducer 4 mounted on the bracket 5 is connected to a motor 6 at the end away from the large disc 2. A heating mechanism 9 is provided on the side of the small disc 3 opposite to the large disc 2. Several circular bolts 7 are provided at intervals around the edge of the large disc 2 and around the periphery of the small disc 3. These circular bolts 7 are located at the front end of the large disc 2 for mounting a tubular workpiece 100. A heat shrink tubing 101 is fitted onto this tubular workpiece 100. The hot air drying mechanism 9 includes a hot air gun 10 and a conical air duct 11 connected to the air outlet of the hot air gun 10. A conical air cover 12 is fitted around the conical air duct 11. The opening of the conical air cover 12 is larger than the opening of the conical air duct 11 and is located above the opening of the conical air duct 11, thereby forming a heat storage cavity 13 between the conical air duct 11 and the conical air cover 12.

[0025] A bearing 43 is provided between the central shaft 41 and the rotating cylinder 42.

[0026] The central shaft 41 of the reducer 4 does not rotate, but the rotating cylinder 42 of the reducer 4 can rotate. Two L-shaped brackets 8 are spaced apart between the side of the hanger 5 opposite to the reducer 4 and the platform 1. The L-shaped brackets 8 stably connect the hanger 5 and the platform 1, greatly reducing the shaking caused by the rotation of the large disc 2.

[0027] The cone-shaped air duct 11 is duckbill-shaped, and the cone-shaped air hood 12 is duckbill-shaped.

[0028] The aforementioned hot air gun 10 is mounted to the side surface of the small disc 3 via a support plate 17.

[0029] The opening of the conical hood 12 has a constrained air outlet 14 with one side arranged parallel to the axis of the hot air gun 10, which can make the hot air blown out by the hot air gun 10 more concentrated on the surface of the heat shrink tubing 101.

[0030] The working principle of this patent is as follows: First, the tubular workpiece 100 is fitted onto the circular plug 7 and the heat shrink sleeve 101 is fitted onto the tubular workpiece 100. Then, the motor 6 drives the large disc 2 to rotate through the reducer 4. When the tubular workpiece 100 on the large disc 2 is moved to the top of the heat drying mechanism 9, the large disc 2 stops rotating. At this time, the hot air blown out by the hot air gun 10 of the heat drying mechanism 9 passes through the conical air pipe 11 and the conical air cover 12 and evenly reaches the surface of the heat shrink sleeve 101 to heat shrink the heat shrink sleeve 101. While the heat drying mechanism 9 is working, if other circular plugs 7 are equipped with tubular workpieces that have been heat-shrinked, the operator can remove the tubular workpiece and install other tubular workpieces 100 to be heat-shrinked. When the heat drying mechanism 9 has finished heat-drying the current tubular workpiece, under the rotation of the large disc 2, another tubular workpiece 100 to be heat-shrinked moves to the top of the heat drying mechanism 9, and then the cycle continues.

[0031] When using the above-mentioned heat shrink tubing shrinking device, the large disc drives the tubular workpiece to rotate circumferentially, while the heating mechanism heats the heat shrink tubing fitted onto the tubular workpiece in sequence. When the heating mechanism heats one of the tubular workpieces, the large disc stops rotating. At this time, the operator can remove the other tubular workpieces that have been heated and replace them with other tubular workpieces to be heat-shrinked, so that the heat shrink tubing shrinking device can efficiently inspect multiple tubular workpieces in a short time.

[0032] Furthermore, by setting up a heat storage cavity to store the high-temperature gas blown out by the hot air gun, it can minimize the temperature difference between the two ends and the center of the heat shrink tubing, ensuring that the heat shrink tubing can be uniformly heat-shrink onto the tubular workpiece.

[0033] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
