Description

Technical Field

[0001] This application relates to the field of adhesive production technology, and in particular to a temperature control system in the adhesive preparation process. Background Technology

[0002] The production of adhesives or glues is a complex chemical process. From raw material preparation to finished product packaging, the entire production process requires precise temperature control and a stable heat source supply. Temperature control systems ensure that each production stage operates under optimal temperature conditions by providing a stable heat source, thereby guaranteeing the stability and consistency of product quality. Existing dispensing devices require adhesives or glues to flow at a suitable temperature during the manufacturing process, providing agile temperature regulation capabilities without damaging their molecular structure.

[0003] A reaction apparatus for the production of pressure-sensitive adhesives, patent number "CN221889902U", includes a tank, an inlet, and an outlet. The tank contains a stirring rod with a spiral band for lifting the material. The tank has a cooling water jacket for cooling, with multiple cooling water pipes extending into the tank. The cooling water jacket also contains multiple heating modules. Temperature sensors are located at the bottom and side walls of the tank. By using a cooling water jacket to cool the material inside the tank, heating modules to heat the material inside the tank, and temperature sensors to accurately detect the temperature inside the tank, the apparatus effectively controls and adjusts the internal temperature of the tank, thus solving the temperature control problem in pressure-sensitive adhesive reaction apparatuses.

[0004] Although the above-mentioned reaction device can control the temperature, the cooling water jacket and the heating module are set in close contact, which can easily cause thermal conflict when adjusting the temperature of the adhesive inside the tank. This will greatly reduce the effect and rate of both heating and cooling, resulting in excessive energy consumption. Utility Model Content

[0005] To address the issue of thermal conflict during temperature regulation inside the tank as described above, and to make the equipment more efficient in temperature control of adhesives or glues and improve energy utilization efficiency, this application provides a temperature control system for the adhesive preparation process.

[0006] The temperature control system for the adhesive preparation process provided in this application adopts the following technical solution:

[0007] A temperature control system for an adhesive preparation process includes a tank with an inlet and an outlet at the top and bottom, respectively. The tank has an inner wall and an outer wall, which together form a sandwich cavity. A spiral cooling pipe is wound around the sandwich cavity, and the cooling pipe is filled with flowing coolant. A rotating sleeve, which is hollow inside the tank and rotatably inserted along its axis, has one end extending out of the top side of the tank and has openings at both the top and bottom. A drive wheel is connected to the end of the rotating sleeve extending out of the tank. A rotating shaft is rotatably inserted inside the rotating sleeve. An AC motor connected to the rotating shaft is installed at the top of the tank. An auger adapted to the internal dimensions of the rotating sleeve is wound along the axis of the rotating shaft. A plurality of heating sleeves are spaced apart on the rotating shaft, and a plurality of heating strips are installed circumferentially on the heating sleeves.

[0008] Optionally, the number of heating bars on the rotating shaft and on the heating sleeves increases sequentially along the axis of the rotating shaft toward the top of the tank.

[0009] Optionally, the auger has a segmented structure, and the heating sleeves and the multiple segments of the auger are distributed in an alternating manner.

[0010] Optionally, a plurality of stirring blades are sleeved on the outer side of the rotating sleeve along the axis. The stirring blades include a central sleeve and a plurality of blades connected to the central sleeve at intervals along the circumference, and the plurality of blades have an angle between them and the radial plane in which the central sleeve is located.

[0011] Optionally, the rotating sleeve is equipped with a plurality of reciprocating components for driving the plurality of stirring blades to move up and down respectively. The reciprocating components include a plurality of positioning contacts that are spaced apart and connected to the inner side of the central sleeve. The plurality of positioning contacts on the same central sleeve are all located on the same radial plane. The outer wall of the rotating sleeve is provided with a wave-shaped groove along the circumference, and the plurality of positioning contacts are slidably disposed in the wave-shaped groove.

[0012] Optionally, a mounting ring is rotatably fitted on the rotating sleeve below each of the stirring blades, and a spring is installed on the mounting ring, with the top side of the spring connected to the central sleeve.

[0023] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0024] This application discloses a temperature control system in the adhesive preparation process.

[0025] Reference Figure 1 A temperature control system for an adhesive preparation process includes a tank 1 with an inlet 11 at the top and an outlet 12 at the bottom. The tank 1 has an inner wall and an outer wall, separated by a gap, forming a sandwich cavity 13. A cooling pipe 131 filled with coolant is installed on the tank 1 within the sandwich cavity 13 to cool the adhesive liquid inside the tank 1. A rotating sleeve 2 is rotatably inserted through the hollow interior of the tank 1 along its axis. One end of the rotating sleeve 2 extends to the top of the tank 1 and is connected to a drive wheel 21. The drive wheel 21 is connected to a drive component, which rotates the drive wheel 21 and the rotating sleeve 2 during operation.

[0026] Reference Figure 2 and Figure 3 Furthermore, a rotating shaft 3 is rotatably installed inside the rotating sleeve 2, and an AC motor 31, which is connected to the rotating shaft 3 for transmission, is installed on the top of the tank body 1. An auger 32 is wound along the axis of the rotating shaft 3, and the auger 32 is adapted to the internal dimensions of the rotating sleeve 2. When the AC motor 31 drives the rotating shaft 3 to rotate, the rotating shaft 3 can drive the auger 32 to rotate, thereby transferring the adhesive liquid inside the tank body 1 from the bottom of the tank body 1 to the top of the tank body 1 within the rotating sleeve 2. Due to the liquid flow, the adhesive liquid that was originally located at the top of the tank body 1 will flow to the bottom of the tank body 1, thus forming a liquid circulation.

[0027] Several heating sleeves 33 are also spaced apart on the rotating shaft 3. Several heating strips 331 are installed on the heating sleeves 33 along the circumference. When the rotating shaft 3 rotates, the adhesive liquid flowing into the rotating sleeve 2 will be heated, and then the adhesive liquid in the tank 1 will be uniformly heated under the circulation.

[0028] For colloidal materials with slow heat transfer, this structure is more effective at heating through circulating flow.

[0029] Preferably, the cooling pipe 131 located in the interlayer cavity 13 is spirally wound on the side wall of the tank 1, and the coolant in the cooling pipe 131 is in a flowing state, thereby enabling the adhesive liquid in the tank 1 to be cooled quickly.

[0030] Reference Figure 3 and Figure 4 Furthermore, the number of heating bars 331 on the rotating shaft 3 and the heating sleeve 33 increases sequentially in the direction toward the top of the tank 1. This structure can provide a tiered heating effect when the adhesive liquid flows upward, avoiding excessive temperature difference during a single heating, which could damage the chemical structure of the adhesive liquid.

[0031] Reference Figure 4 Furthermore, the auger 32 has a segmented structure, with several heating sleeves 33 and multiple auger segments 32 arranged in an alternating pattern. This structure effectively increases the contact area between the adhesive liquid and the heating strip 331, thereby further improving energy utilization efficiency. Simultaneously, this structure also extends the time that some of the adhesive liquid remains in the position of the heating strip 331, improving overall heating efficiency.

[0032] Reference Figure 3 and Figure 5A plurality of stirring blades 4 are fitted along the axial direction on the outer wall of the rotating sleeve 2. When the rotating sleeve 2 rotates, it drives the stirring blades 4 to rotate, thereby stirring the adhesive liquid outside the rotating sleeve 2 inside the tank 1 and helping it to heat up quickly and evenly. The stirring blades 4 include a central sleeve 41 and a plurality of blades 42 connected to the central sleeve 41 at intervals along the circumference, and the plurality of blades 42 are at an angle to the radial plane in which the central sleeve 41 is located. That is, the plurality of blades 42 are all installed at an angle, thereby stirring the adhesive liquid to flow downward.

[0033] Reference Figure 5 and Figure 6 Furthermore, the rotating sleeve 2 is equipped with several reciprocating components 5 for driving the stirring blades 4 to move up and down. The number of reciprocating components 5 corresponds one-to-one with the number of stirring blades 4, and they are all located below the stirring blades 4. Specifically, each reciprocating component 5 includes several positioning contacts 51 spaced apart and connected to the inner side of the central sleeve 41, and the positioning contacts 51 on the same central sleeve 41 are all located on the same radial plane. The outer wall of the rotating sleeve 2 is provided with several wave-shaped grooves 52 that correspond one-to-one with the central sleeve 41, and the positioning contacts 51 on the same central sleeve 41 are all slidably connected in the same wave-shaped groove 52.

[0034] When the rotating sleeve 2 drives the stirring blade 4 to rotate, the positioning contact 51 will slide up and down in the wave ring groove 52 due to the resistance of the fluid, thereby driving the central sleeve 41 and several blades 42 to move up and down, providing a longitudinal stirring effect for the adhesive liquid, helping the adhesive liquid to flow smoothly and be heated evenly.

[0035] Reference Figure 3 and Figure 6 Furthermore, a mounting ring 53 is rotatably fitted on the rotating sleeve 2 below each stirring blade 4, and a spring 54 is installed on the mounting ring 53. The top side of the spring 54 abuts against the central sleeve 41, which makes the rotation of the central sleeve 41 more regular and can offset some of the resistance generated by the adhesive liquid on the stirring blade 4 when it flows, making the stirring blade 4 rotate more smoothly.

[0036] The implementation principle of a temperature control system in the adhesive preparation process according to an embodiment of this application is as follows:

[0037] This application drives the circulation of adhesive liquid inside the tank 1 by rotating the sleeve 2 and rotating the auger 32 that passes through the sleeve 2. At the same time, the heating strip 331 on the rotating shaft 3 located inside the sleeve 2 can circulate and heat the adhesive in combination with the above structure, and form a separated heating and cooling system with the cooling pipe 131 wound in the interlayer cavity 13 of the tank 1, thereby improving the heating and cooling capacity of the equipment and the energy utilization efficiency.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
