Description

Technical Field

[0001] This utility model relates to the field of cooling, specifically to a cooling device for UV adhesive production. Background Technology

[0002] UV adhesive is a type of adhesive that can cure rapidly under ultraviolet (UV) irradiation. It is widely used in many industries such as electronics, optics, medical equipment, and automobile manufacturing for bonding and sealing various materials. Temperature control is a very important factor in the production process of UV adhesive. If the temperature during the production process is too high, it may cause the UV adhesive to cure prematurely or affect its performance. Therefore, cooling devices play a crucial role in the production process of UV adhesive.

[0003] Chinese utility model patent CN213300585U discloses a cooling device for UV adhesive production. The reactor is located at the top of a cooling tower, with two bases respectively located on the ground on the front and back sides of the cooling tower. There are two fixed columns fixed to the two bases, and two stabilizing blocks with their lower ends connected to the upper ends of the two fixed columns respectively. The cooling device designed in this patent improves the cooling effect by indirectly controlling the flow rate of the coolant through spiral cooling pipes and temperature and pressure sensors. However, this device has certain limitations. Although the four spiral cooling pipes are vertically arranged inside the reactor and connected to the annular pipe, because they are static fixed structures, the contact surface with the UV adhesive may be relatively small. This limits the heat exchange efficiency, and the heat in the central area of ​​the reactor is difficult to dissipate, easily forming a local high-temperature zone, which affects the cooling performance of the entire system. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a cooling device for UV adhesive production, which achieves efficient and continuous cooling of UV adhesive.

[0005] The technical solution is as follows: A cooling device for UV adhesive production includes a base plate and a reaction vessel. The base plate serves as the supporting carrier for the cooling device, and the reaction vessel is fixedly installed on the base plate. An inlet for adding UV adhesive to be cooled is provided on the upper side wall of the reaction vessel, and an outlet for discharging cooled UV adhesive is provided at the bottom of the reaction vessel. The device also includes: a rotating shaft rotatably installed inside the reaction vessel, the rotating shaft being a hollow shaft with its lower end connected to a connecting pipe at the bottom of the reaction vessel; a cover plate, snapped into the top opening of the reaction vessel; a connecting frame rotatably installed on the upper part of the inner wall of the reaction vessel, the top of the connecting frame being connected to a connecting pipe, the connecting pipe rotating upwards and passing through the cover plate; the rotating shaft and the connecting frame being fixedly connected, the connecting frame being a three-way bifurcated hollow frame and not directly connected to the rotating shaft; and three sets of heat dissipation pipes, arranged on the rotating shaft and located below the connecting frame. The reactor consists of three sets of heat dissipation pipes, each with multiple pipes vertically spaced and connected to the rotating shaft. The three sets of heat dissipation pipes correspond to three branching points of the connecting frame. A first connecting pipe connects the connecting frame and the uppermost heat dissipation pipe, located on the heat dissipation pipe at a point away from the rotating shaft. A second connecting pipe connects adjacent heat dissipation pipes within the same set. A support is fixed to the outer wall of the reactor, and a drive mechanism is installed on the support to rotate the connecting pipe. A circulating cooling assembly is installed on the outer wall of the reactor. This assembly circulates cooling water to the connecting pipe to cool the UV adhesive. The drive mechanism drives the connecting frame, rotating shaft, and heat dissipation pipes to rotate within the reactor via the connecting pipe. The circulating cooling assembly continuously supplies cooling water from the top into the connecting pipe, allowing heat exchange between the cooling water and the UV adhesive, thus cooling the UV adhesive.

[0006] Furthermore, the connecting pipes between adjacent heat dissipation pipes in the same group are arranged at varying distances from the rotating shaft. Cooling water can flow downwards through the connecting pipes and fill each heat dissipation pipe, allowing the cooling water in the internal pipes of the reactor to fully contact the UV adhesive. This ensures that the cooling water in the pipes can fully contact the UV adhesive and efficiently remove the heat from the UV adhesive in the reactor, thereby improving the cooling efficiency of the UV adhesive.

[0007] Furthermore, the driving component includes a motor and a belt assembly. The motor is fixedly mounted on the bracket, and the output shaft of the motor is connected to the connecting pipe via the belt assembly. The motor drives the connecting pipe to rotate via the belt assembly, causing the connecting frame, rotating shaft, and heat dissipation pipe to rotate inside the reactor. This, combined with the cooling water flowing through the rotating shaft and heat dissipation pipe, increases the heat exchange area between the cooling water and the UV adhesive, achieving efficient cooling of the UV adhesive.

[0008] Furthermore, the circulating cooling assembly includes a circulating chiller and water pipes. The circulating chiller is installed on the outer wall of the reactor. The outlet of the circulating chiller is sealed and connected to the connecting pipe via a water pipe. The inlet of the circulating chiller is sealed and connected to the connecting pipe at the lower end of the rotating shaft via a water pipe. The water pipe does not rotate with the connecting pipe. The circulating chiller continuously provides cooling water to the cooling pipes inside the reactor through the water pipe.

[0009] Furthermore, an exhaust pipe is connected to the upper outer wall of the reactor, and a valve is installed on the exhaust pipe. The valve is used to control the opening and closing of the exhaust pipe. The exhaust pipe is used to discharge the hot air generated when the UV glue in the reactor is cooled, so as to avoid the heat at the top of the reactor being difficult to dissipate, which would cause uneven cooling of the UV glue in the upper and lower layers of the reactor.

[0010] Furthermore, it also includes an air pump and an air inlet pipe. The air pump is installed on the outer wall of the reactor and is connected to the inner top of the reactor through the air inlet pipe. The air pump continuously introduces external air into the reactor through the air inlet pipe, so that the introduced air quickly replaces the hot air generated when the UV adhesive is cooled inside the reactor, thereby further improving the cooling efficiency of the UV adhesive.

[0011] The beneficial effects are as follows: 1. Through the heat dissipation pipe layout and connecting pipe structure, the cooling water can fully and evenly contact the UV glue in the reactor. The connecting pipes between adjacent heat dissipation pipes in the same group are arranged with alternating distances from the rotating shaft to ensure that the cooling water can flow smoothly through each heat dissipation pipe and fill it, thereby achieving comprehensive heat exchange of the UV glue.

[0012] 2. This utility model can make the connecting frame, rotating shaft and heat dissipation pipe rotate continuously in the reactor through the design of the driving component. With the cooling water provided by the circulating cooling component, the contact area between the cooling water and the UV adhesive is greatly increased, which further enhances the speed and efficiency of heat transfer and achieves faster and more effective cooling of the UV adhesive.

[0013] 3. This utility model is equipped with an air inlet pipe, an air outlet pipe, and an air pump. The air pump continuously supplies fresh air into the reactor through the air inlet pipe, quickly replacing the hot air generated during the cooling process of the UV adhesive, maintaining a good heat exchange environment inside the reactor, helping to maintain stable pressure inside the reactor, and providing a more uniform and stable cooling condition for the UV adhesive.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0020] A cooling device for UV adhesive production, such as Figures 1-3As shown, the device includes a base plate 1 and a reactor 2. The base plate 1 serves as the supporting carrier for this cooling device. The reactor 2 is fixedly installed on the base plate 1. The upper side wall of the reactor 2 is provided with an inlet 12 for adding UV adhesive to be cooled, and the bottom of the reactor 2 is provided with an outlet 11 for discharging the cooled UV adhesive. The device also includes: a rotating shaft 5, rotatably installed inside the reactor 2, the rotating shaft 5 being a hollow shaft with its lower end connected to the bottom connecting pipe of the reactor 2; a cover plate 6, snapped into the top opening of the reactor 2; and a connecting frame 8, rotatably installed on the reactor 2. The upper part of the inner wall, the top of the connecting frame 8 is connected to the connecting pipe 81, the connecting pipe 81 rotates upward and passes through the cover plate 6, the rotating shaft 5 and the connecting frame 8 are fixedly connected, the connecting frame 8 is a hollow frame with three branches and is not directly connected to the rotating shaft 5; there are three sets of heat dissipation pipes 9, which are set on the rotating shaft 5 and located below the connecting frame 8. Each set of heat dissipation pipes 9 has multiple pipes and is vertically spaced and connected to the rotating shaft 5. The three sets of heat dissipation pipes 9 correspond to the three branches of the connecting frame 8; the connecting pipe 82 connects the connecting frame 8 and the uppermost heat dissipation pipe 9. Located on the heat dissipation pipe 9, away from the rotating shaft 5; connecting pipe 2 10, connecting adjacent heat dissipation pipes 9 in the same group. The distance between the connecting pipe 2 10 and the rotating shaft 5 of adjacent heat dissipation pipes 9 in the same group alternates. Cooling water can flow downward through the connecting pipe 2 10 and fill each heat dissipation pipe 9, so that the cooling water in the pipes inside the reactor 2 can fully contact the UV adhesive, and efficiently remove the heat of the UV adhesive in the reactor 2, improving the cooling efficiency of the UV adhesive; bracket 3, fixed on On the outer wall of the reactor 2, a drive component is provided on the support 3 for driving the connecting pipe 81 to rotate; a circulating cooling assembly is provided on the outer wall of the reactor 2. The circulating cooling assembly is used to circulate cooling water for cooling UV adhesive into the connecting pipe 81. The drive component drives the connecting frame 8, the rotating shaft 5 and the heat dissipation pipe 9 to rotate inside the reactor 2 through the connecting pipe 81. In conjunction with the circulating cooling assembly, cooling water is continuously circulated from the top into the connecting pipe 81, so that the circulated cooling water and the UV adhesive exchange heat and cool the UV adhesive.

[0021] like Figure 1 As shown, the driving components include a motor 4 and a belt assembly 7. The motor 4 is fixedly mounted on the bracket 3. The output shaft of the motor 4 is connected to the connecting pipe 81 through the belt assembly 7. The motor 4 drives the connecting pipe 81 to rotate through the belt assembly 7, causing the connecting frame 8, the rotating shaft 5, and the heat dissipation pipe 9 to rotate inside the reactor 2. In conjunction with the cooling water flowing through the rotating shaft 5 and the heat dissipation pipe 9, the heat exchange area between the cooling water and the UV adhesive is increased, achieving the effect of efficient cooling of the UV adhesive.

[0022] like Figure 1 and Figure 2As shown, the circulating cooling assembly includes a circulating chiller 13 and a water pipe 14. The circulating chiller 13 is installed on the outer wall of the reactor 2. The outlet of the circulating chiller 13 is sealed and connected to the connecting pipe 81 through the water pipe 14. The inlet of the circulating chiller 13 is sealed and connected to the connecting pipe at the lower end of the rotating shaft 5 through the water pipe 14. The water pipe 14 does not rotate with the connecting pipe 81. The circulating chiller 13 continuously provides cooling water to the cooling pipes inside the reactor 2 through the water pipe 14.

[0023] like Figure 4 As shown, an exhaust pipe 17 is connected to the upper outer wall of the reactor 2. A valve 18 is installed on the exhaust pipe 17. The valve 18 is used to control the opening and closing of the exhaust pipe 17. The exhaust pipe 17 is used to discharge the hot air generated when the UV glue inside the reactor 2 is cooled, so as to avoid the heat at the top of the reactor 2 being difficult to dissipate, resulting in uneven cooling effect of the UV glue in the upper and lower layers of the reactor 2. An air pump 15 is installed on the outer wall of the reactor 2. The air pump 15 is connected to the inner top of the reactor 2 through an air inlet pipe 16. The air pump 15 continuously introduces external air into the reactor 2 through the air inlet pipe 16, so that the introduced air quickly replaces the hot air generated when the UV glue inside the reactor 2 is cooled, further improving the cooling efficiency of the UV glue.

[0024] When using this cooling device to cool UV adhesive, the UV adhesive to be cooled is first added to the reactor 2 through the feed inlet 12. Simultaneously, the circulating cooling assembly starts operating, with the circulating chiller 13 generating cooling water, which is then sealed and connected to the connecting pipe 81 via the water pipe 14. The cooling water then enters the connecting frame 8 through the connecting pipe 81. The motor 4 is then activated; it is connected to the connecting pipe 81 via the belt assembly 7, thus driving the connecting pipe 81 to rotate. Since the connecting frame 8, the rotating shaft 5, and the heat dissipation pipes 9 are all fixedly connected to the connecting pipe 81, the entire structure rotates together with the connecting pipe 81 inside the reactor 2. After being distributed within the connecting frame 8, the cooling water reaches the uppermost heat dissipation pipe 9 through the first connecting pipe 82, and then flows through adjacent heat dissipation pipes 9 in the same group via the second connecting pipe 10 until all heat dissipation pipes 9 are filled, thus ensuring the cooling water... The system ensures full contact between the UV adhesive in the reactor 2, increasing the heat exchange area between them. This ensures that the cooling water can effectively flow downwards and exchange heat with the surrounding UV adhesive through the heat dissipation pipe 9. Simultaneously, the cooled UV adhesive, after carrying away heat, is discharged through the outlet 11 at the bottom of the reactor 2. The cooling water that has absorbed heat flows back to the circulating chiller 13 through the connecting pipe at the lower end of the rotating shaft 5, thus completing a cooling cycle. To ensure uniform temperature distribution inside the reactor 2, the upper outer wall of the reactor 2 is equipped with an air outlet pipe 17 with a valve 18 to discharge the hot air generated during the cooling process in a timely manner, avoiding uneven cooling of the upper and lower layers of UV adhesive inside the reactor 2. In addition, the air pump 15 continuously introduces external air into the reactor 2 through the air inlet pipe 16 to quickly replace the hot air generated during the cooling of the UV adhesive, further improving the cooling efficiency.
