Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of sealant mixing technology, and more specifically to a mixing device for the production of water-based sealants. Background Technology
[0002] Water-based sealants are functional adhesive sealing materials that use water as a dispersion medium. They are environmentally friendly, safe, and easy to apply, and are widely used in construction, automotive, and electronics industries. The production of water-based sealants typically requires multiple functions, such as heating, stirring, high-speed dispersion, and vacuuming. Different types of water-based sealants, as well as different production scales and environments, have varying requirements for mixing equipment.
[0003] Traditional mixing devices add raw materials by simply adding them to the device and then stirring them. However, this method only achieves a basic stirring effect. The resulting mixture is sticky and tends to adhere to the inner wall of the mixing device, affecting its subsequent use. Furthermore, traditional mixing devices cannot effectively achieve product circulation and mixing; the stirring alone may not ensure uniform mixing, thus impacting product quality.
[0004] A search revealed that Chinese Patent Publication No. CN202210640709.2 discloses a high-strength silicone-free sealant mixing device, comprising: a base, on the top of which a mixing tank is mounted; an adjustment part located on one side of the base, used to adjust the stirring position of a stirring part; and a stirring part located inside the mixing tank, used to stir the sealant inside the mixing tank.
[0005] While the device in the aforementioned patent can adjust the mixing unit by moving the support plate up and down via a lead screw and slider during mixing, the range of vertical adjustment of the mixing unit within the mixing tank is limited. This can lead to stratification of the raw materials during mixing, hindering the efficient mixing of the sealant and thus affecting product quality. Utility Model Content

Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figure 1-7 In this embodiment of the present invention, a mixing device for producing water-based sealant includes a mixing cylinder 1; a stirring assembly 2 and a cooperating assembly 3 are respectively installed at the top and bottom of the mixing cylinder 1; wherein, the mixing cylinder 1 includes a cylinder body 10; a first feed pipe 11 and a second feed pipe 12 are integrally arranged on the cylinder body 10; a first solenoid valve 13 is provided between the first feed pipe 11 and the second feed pipe 12 and the cylinder body 10; the bottom of the first feed pipe 11 and the second feed pipe 12 are integrally arranged with a negative pressure pipe 15; a fourth solenoid valve 17 is fixedly installed on the connecting pipe between the second feed pipe 12 and the negative pressure pipe 15; a third solenoid valve 16 is also provided on the negative pressure pipe 15; the third solenoid valve 16 is located between the first feed pipe 11 and the second feed pipe 12.
[0029] The negative pressure pipe 15 is welded and fixed to the first circulation pipe 42 in the extraction assembly 4; a second solenoid valve 14 is fixedly installed at one end of the negative pressure pipe 15 near the first circulation pipe 42.
[0030] The stirring assembly 2 includes a top cover 20, which is fixedly installed with the cylinder 10. A drive motor 21 is fixedly installed on the top cover 20. The output shaft of the drive motor 21 is fixedly installed with the stirring shaft 22 via a coupling. The stirring shaft 22 is located inside the cylinder 10. Multiple sets of stirring blades 23 are fixedly installed on the stirring shaft 22. A scraper 24 is also fixedly installed at the bottom of the stirring shaft 22. The scraper 24 is bent. The surface of the scraper 24 is in contact with the inner wall of the conical cylinder 30 in the mating assembly 3.
[0031] By adopting the above technical solution, during use, the first feed pipe 11 and the second feed pipe 12 on the cylinder 10 are respectively matched with different material tanks. The negative pressure pump 41 enables the first feed pipe 11 and the second feed pipe 12 to be fed individually or simultaneously, thereby effectively ensuring the quality and efficiency of material addition. When feeding material through the first feed pipe 11 alone, the negative pressure pump 41 is connected to the negative pressure pipe 15 through the first circulation pipe 42, and the second solenoid valve 14 and the third solenoid valve 16 on the negative pressure pipe 15 are activated. When the second feed pipe 12 is opened, the fourth solenoid valve 17 between the second feed pipe 12 and the negative pressure pipe 15 is closed, and the first solenoid valve 13 on the first feed pipe 11 is opened. The negative pressure effect of the negative pressure pump 41 enables the material to be added into the cylinder 10 through the first feed pipe 11. Similarly, when adding material separately through the second feed pipe 12, the third solenoid valve 16 on the negative pressure pipe 15 is closed, and the fourth solenoid valve 17 between the second feed pipe 12 and the negative pressure pipe 15 is opened, thereby adding the corresponding material into the cylinder 10 through the second feed pipe 12.
[0032] In this embodiment, the conical cylinder 30 is fixedly installed at the bottom of the cylinder body 10; the bottom of the conical cylinder 30 is integrally provided with multiple support rods 31 and a discharge pipe 32; wherein, a discharge valve 33 is installed on the discharge pipe 32.
[0033] In this embodiment, the extraction component 4 further includes a support base 40; a negative pressure pump 41 is fixedly installed on the support base 40; the discharge end of the negative pressure pump 41 is fixedly installed with the first circulation pipe 42; the other end of the first circulation pipe 42 is fixedly installed with the top cover 20.
[0034] By adopting the above technical solution, after the material is added, the drive motor 21 on the top cover 20 drives the stirring shaft 22 and stirring blade 23 to rotate at high speed, so as to achieve the effect of stirring and mixing the added material. During the stirring process, in the early stage of the formation of the sealant, the raw material may stick to the inner wall of the conical cylinder 30. In order to ensure the stirring and mixing effect, the scraper 24 at the bottom of the stirring shaft 22 scrapes up the material stuck to the inner wall of the conical cylinder 30, and the mixing and molding are achieved by stirring.
[0035] Furthermore, a second circulation pipe 43 is fixedly installed at the feed end of the negative pressure pump 41; the end of the second circulation pipe 43 away from the negative pressure pump 41 extends into the interior of the conical cylinder 30; wherein, a circulation switch 45 is fixedly installed on the second circulation pipe 43.
[0036] In this embodiment, a controller 44 is also fixedly installed on the support base 40 by a support rod; the controller 44 is electrically connected to multiple solenoid valves through wires.
[0037] By adopting the above technical solution, in order to ensure the mixing quality of the sealant and the working efficiency of the mixing device during the mixing process, the cooperation between the negative pressure pump 41 and the first circulation pipe 42 and the second circulation pipe 43 is used to achieve the effect of circulating the mixed material. During circulation, the second solenoid valve 14 at the end of the negative pressure pipe 15 near the first circulation pipe 42 is closed. The second circulation pipe 43 at the feed end of the negative pressure pump 41 draws the material inside the cylinder 10 into the negative pressure pump 41, and then the first circulation pipe 42 at the discharge end transmits the drawn material to the top of the cylinder 10, thereby effectively achieving the effect of circulating and mixing the material, thus effectively ensuring the mixing quality.
[0038] After the sealant is mixed, the discharge valve 33 on the discharge pipe 32 is opened by the controller 44 to transfer the mixed sealant to the next process.
[0039] The working principle of this utility model is as follows: the first feed pipe 11 and the second feed pipe 12 are respectively connected to different raw material tanks through connecting pipes. When material is added through the first feed pipe 11, the controller 44 opens the second solenoid valve 14 and the third solenoid valve 16 on the negative pressure pipe 15. At the same time, the first solenoid valve 13 on the first feed pipe 11 is opened. The negative pressure effect of the negative pressure pump 41 enables the material to be added into the cylinder 10 through the first feed pipe 11.
[0040] When material is added individually through the second feed pipe 12, the controller 44 opens the second solenoid valve 14 and the third solenoid valve 16 between the second feed pipe 12 and the negative pressure pipe 15, and opens the first solenoid valve 13 on the second feed pipe 12. Then, through the negative pressure effect of the negative pressure pump 41, the second feed pipe 12 is fed individually.
[0041] When the first feed pipe 11 and the second feed pipe 12 need to feed simultaneously, the two first solenoid valves 13, the second solenoid valve 14, the third solenoid valve 16 and the fourth solenoid valve 17 are all opened. Through the negative pressure effect, the effect of adding two or more raw materials at the same time is achieved.
[0042] During the material addition process, the drive motor 21 on the top cover 20 drives the stirring shaft 22 and stirring blade 23 to rotate, thereby mixing the added material. During the mixing process, the material at the bottom may settle and stick to the inner wall of the conical cylinder 30. As the stirring shaft 22 rotates, the scraper 24 rotates synchronously along the inner wall of the conical cylinder 30, thereby scraping up the stuck material, and then the stirring shaft 22 and stirring blade 23 will fully mix it.
[0043] During the mixing process, the controller 44 opens the circulation switch 45 on the second circulation pipe 43. Through the cooperation between the negative pressure pump 41, the first circulation pipe 42, and the second circulation pipe 43, the sealant inside the cylinder 10 is effectively extracted and circulated, thereby effectively ensuring the mixing quality of the sealant during mixing. At the same time, it can also effectively reduce the working time of the mixing device and improve production efficiency.
[0044] After the mixing is completed, the discharge valve 33 on the discharge pipe 32 is opened by the controller 44 to transfer the mixed sealant to the next process. During the discharge process, the scraper 24 is driven to rotate by the stirring shaft 22, which effectively ensures that the sealant on the inner wall of the conical cylinder 30 is completely discharged to avoid affecting the quality of the next mixing.
[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
