Detailed implementation mode

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0024] Please refer to Figures 1-4 , this embodiment provides a preparation device for acrylate pressure-sensitive adhesive, including a stirring tank 100. A driving motor 200 is fixedly connected to the top of the stirring tank 100. The output shaft of the driving motor 200 extends into the inner cavity of the stirring tank 100 and is connected with a hollow column 202. A cleaning component for cleaning the inner wall of the stirring tank 100 is arranged in the inner cavity of the hollow column 202. A preparation component for preparing acrylate pressure-sensitive adhesive is arranged on the surface of the hollow column 202 located in the inner cavity of the stirring tank 100;

[0025] Among them, the cleaning component includes a water tank 300 fixedly installed on one side surface of the stirring tank 100. A circulation pipe 102 is inserted into the mouth of the water tank 300. The other end of the circulation pipe 102 communicates with the inner cavity of the cavity 207. The drainage end of the water tank 300 communicates with a circulation pump 301. The water outlet end of the circulation pump 301 communicates with a water pipe 302. The other end of the water pipe 302 extends to the bottom of the stirring tank 100 and communicates with a water distribution pipe 302. One group of water distribution ends of the water distribution pipe 302 communicates with the inner cavity of the cavity 207. The other end of the water distribution pipe 302 communicates with a rotary joint 400. The rotary water outlet end of the rotary joint 400 communicates with the inner cavity of the hollow column 202. Water outlet holes 208 are formed on the surface of the hollow column 202. A closing component for closing the water outlet holes 208 is arranged on the inner wall of the hollow column 202. Through the setting of the cleaning component, when the circulation pump 301 and the driving motor 200 are started, the circulation pump 301 injects the solution into the inner cavity of the hollow column 202 and the cavity 207. The solution is rotated and flushed towards the inner wall of the stirring tank 100 through the water outlet holes 208, flushing the raw materials remaining on the surface of the stirring tank 100, and the solution injected into the cavity 207 keeps the stirring tank 100 at a relatively stable temperature, preventing the raw materials on the inner wall of the stirring tank 100 from solidifying, so as to facilitate the staff to clean the inner wall of the stirring tank 100. It is worth noting that the corresponding solution can be selected according to needs and injected into the cavity 207, which can improve the heating or cooling efficiency of the materials in the stirring tank 100. Moreover, the cavity 207 has a large contact area with the materials, and the excess solution flows back into the water tank 300 through the circulation pipe 102, so as to have a good circulating heating or cooling effect on the materials in the stirring tank 100.

[0026] Furthermore, the preparation component includes several groups of connecting rings 203 fixedly connected to the surface of the hollow column 202. Connecting plates 204 are fixedly connected to both sides of the connecting rings 203. One end of the connecting plates 204 on the same side is fixedly connected with an arc-shaped plate 205. Scraping plates 206 are fixedly connected to the opposite surfaces of the two arc-shaped plates 205. The top of the scraping plates 206 is closely attached to the inner wall of the top of the mixing tank 100. Through the arrangement of the arc-shaped plates 205 and the scraping plates 206, the driving motor 200 drives the connecting rings 203 on the surface of the hollow column 202 to rotate, and the connecting rings 203 drive the arc-shaped plates 205 and the scraping plates 206 to rotate along the inner wall of the mixing tank 100, so as to scrape off the residual raw materials on the surface of the mixing tank 100, improving the cleaning effect on the inner wall of the mixing tank 100.

[0027] Preferably, the closing component includes a limiting groove 404 opened in the column body of the hollow column 202 and corresponding to the water outlet hole 208. A blocking plate 401 is slidably connected to the inner cavity of the limiting groove 404. A hole 402 corresponding to the water outlet hole 208 is opened on the surface of the blocking plate 401. A connecting block 406 is fixedly connected to the surface of the blocking plate 401. One end of the connecting block 406 slidably penetrates through the inner wall of the hollow column 202 and is fixedly connected with a connecting disc 403. A spring 405 is fixedly connected to the top of the connecting disc 403. The other end of the spring 405 is fixedly connected to the top inner cavity of the hollow column 202. Through the arrangement of the connecting disc 403 and the spring 405, the circulating pump 301 injects the solution into the inner cavity of the hollow column 202, and the blocking plate closes the water outlet hole 208. When the solution in the hollow column 202 reaches a certain pressure, the connecting disc 403 is jacked up, so that the hole 402 on the surface of the blocking plate 401 coincides with the water outlet hole 208, thereby further increasing the water pressure of the sprayed solution and improving the flushing effect on the inner wall of the mixing tank 100.

[0028] It should be noted that a reinforcing rib 209 is fixedly connected to the bottom of the scraping plate 206, and the other end of the reinforcing rib 209 is fixedly connected to the surface of the arc-shaped plate 205, increasing the connection stability between the scraping plate 206 and the arc-shaped plate 205.

[0029] Furthermore, sealing bearings 201 are sleeved at the positions where the surface of the hollow column 202 contacts the tank body of the mixing tank 100, and the sealing bearings 201 are fixedly inserted into the tank body of the mixing tank 100, reducing the friction between the hollow column 202 and the tank body of the mixing tank 100.

[0030] Furthermore, a feed pipe 101 and a discharge pipe 103 are respectively connected to the top and bottom of the mixing tank 100. Valves 303 are connected between the two water distribution ends of the water distribution pipe 302 and the discharge pipe 103. Through the setting of the valves 303, it is convenient to close the water distribution ends of the water distribution pipe 302 and the discharge pipe 103 according to needs.

[0031] Working principle:

[0032] First, inject the solution into the water tank 300, then close the valve 303 at the discharge pipe 103 and the rotary joint 400, and then start the circulation pump 301 to continuously inject the solution into the cavity 207. At this time, the raw material for preparing the acrylic pressure-sensitive adhesive is injected into the inner cavity of the stirring tank 100 through the feed pipe 101, and the drive motor 200 is started. The drive motor 200 drives the connecting ring 203 on the surface of the hollow column 202 to rotate, and the connecting ring 203 drives the arc plate 205 to rotate along the inner wall of the stirring tank 100, so as to fully mix and stir the materials in the stirring tank 100. When the raw materials are mixed, open the valve 303 at the discharge pipe 103 to discharge the raw materials, then close the valve 303, and close the valve 303 at one end of the water divider for injecting the solution into the inner cavity, and open the rotary joint 400. The valve 303 at the adapter 400 is opened, and the circulation pump 301 and the drive motor 200 are started. The circulation pump 301 injects the solution into the inner cavity of the hollow column 202. When the solution in the hollow column 202 reaches a certain pressure, the connecting plate 403 is lifted upward, thereby driving the blocking plate 401 to slide upward along the limiting groove, and when the connecting plate 403 is close to the top inner wall of the hollow column 202, the hole 402 on the surface of the blocking plate 401 coincides with the water outlet 208, so that the solution is flushed toward the inner wall of the stirring tank 100 through the water outlet 208, and the inner wall of the stirring tank 100 is cleaned in cooperation with the arc plate 205 and the scraper 206, thereby improving the cleaning effect of the inner wall of the stirring tank 100. When the stirring tank 100 is cleaned, the valve 303 at the discharge pipe 103 is opened to discharge the solution.
