Description

Technical Field

[0001] This utility model relates to the field of silicone sealant production technology, specifically to a cleaning device for silicone sealant production cylinders. Background Technology

[0002] Silicone sealant is a type of ointment that hardens into a tough, rubber-like solid upon contact with moisture in the air. During production, silicone sealant is temporarily stored in a container to facilitate subsequent processing steps.

[0003] According to the silicone sealant production cylinder cleaning device disclosed in Chinese Patent Publication No. CN218797950U, this patent uses a roller cleaning mechanism to scrape off the cured silicone sealant on the inner wall of the silicone sealant production cylinder, and a brush cleaning mechanism to clean the residual silicone sealant on the inner wall of the cylinder. An electric push rod drives the sliding sleeve to move up and down, thereby driving the roller cleaning mechanism and the brush cleaning mechanism to move up and down to clean the silicone sealant production cylinder, thus achieving a better cleaning effect and improving work efficiency.

[0004] Because silicone adhesive has a certain degree of stickiness, when brushing it for cleaning, a large amount of silicone adhesive will adhere to its surface and interior. Since silicone adhesive hardens upon contact with air, the brush will also become covered in silicone adhesive, making it difficult to clean. If not cleaned, the brush covered in silicone adhesive will lose its original brushing and cleaning ability, thus affecting the actual cleaning effect. In response to this problem, this application makes targeted improvements based on the characteristics of silicone adhesive and provides a silicone adhesive production cylinder cleaning device to solve the above problems.

[0023] 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.

[0024] Please see Figures 1 to 3This utility model provides a technical solution: a cleaning device for a silicone sealant production cylinder, including a cylinder body 1, a reciprocating screw 2 fixedly installed on the inner bottom wall of the cylinder body 1, and a cleaning component 300 installed on the outer side of the reciprocating screw 2; through the cooperation between the reciprocating screw 2 on the inner side of the cylinder body 1 and the cleaning component 300, the cylinder containing silicone sealant can be effectively cleaned. The silicone sealant on the inner wall of the cylinder can be effectively scraped off by the annular scraping method, and the silicone sealant on the inner wall can be further scraped by the annular shovel structure, thereby achieving a comprehensive and effective scraping cleaning effect, and it is also easy to clean the cleaning structure with silicone sealant attached, which greatly reduces the difficulty of cleaning and improves the practicality of the silicone sealant production cylinder cleaning device.

[0025] In this embodiment, the cleaning component 300 is a structure used to clean the silicone sealant cartridge.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the cleaning assembly 300 includes a reciprocating cylinder 301 threaded to the outside of the reciprocating screw 2, five connecting rods 302 fixed to the outside of the reciprocating cylinder 301, an annular frame 303 fixed between the outside of the five connecting rods 302, an annular scraper 304 fixed to the bottom of the annular frame 303, several fixing rods 305 fixed to the bottom of the annular frame 303, and a sloping scraper 306 fixed to the side of the fixing rods 305 away from the reciprocating cylinder 301; a power mechanism for driving the reciprocating cylinder 301 to rotate is installed between the tops of the five connecting rods 302.

[0027] The power mechanism includes a mounting box 307 fixed between the tops of the five connecting rods 302, a servo motor 308 fixedly mounted on the bottom wall of the mounting box 307, a drive gear 309 fixedly mounted on the output shaft of the servo motor 308, and a driven gear 310 fixedly mounted on the outside of the reciprocating cylinder 301; a liquid level sensor 311 is fixedly mounted on the bottom of the first connecting rod 302 on the left.

[0028] It should be noted that the top and bottom of the mounting box 307 are both penetrated by the top of the reciprocating cylinder 301, allowing the mounting box 307 to rotate on the outside of the reciprocating cylinder 301. The outer side of the drive gear 309 and the outer side of the driven gear 310 mesh with each other, allowing the servo motor 308 to drive the driven gear 310 to rotate through the drive gear 309, thereby causing the reciprocating cylinder 301 to rotate. The reciprocating screw 2 is fixed, thus enabling the reciprocating cylinder 301 to perform reciprocating lifting and lowering motion on the outside of the reciprocating screw 2.

[0029] In addition, the outer side of the annular scraper 304 and the inner side of the barrel body 1 are in contact with each other, and the outer side of the inclined scraper 306 and the inner side of the barrel body 1 are in contact with each other, so that the annular scraper 304 and the inclined scraper 306 can scrape and clean the inner side of the barrel body 1. The top of the connecting rod 302 is arc-shaped, which can reduce the area of ​​silicone sealant accumulating on its top.

[0030] It should also be noted that a cover 401 is detachably connected to the top of the barrel body 1. A feed pipe 402 is inserted through and fixed to the top of the cover 401. An inner splined cylinder 403 is fixed to the inner top wall of the cover 401. A limit plate 404 is fixedly installed at the top of the reciprocating screw 2. An outer splined shaft 405 is fixed to the top of the limit plate 404. A discharge pipe 406 is fixed to the bottom of the barrel body 1. The feed pipe 402 is located outside the mounting box 307. The circular motion trajectory of the liquid level sensor 311 is located between the mounting box 307 and the opposite side of the feed pipe 402, so that the silicone glue discharged from the feed pipe 402 will not directly contact the mounting box 307 and the liquid level sensor 311. The liquid level sensor 311 can maintain the liquid level of the silicone glue inside the barrel body 1 at a certain height, and the maximum height does not exceed the top of the inclined scraper 306, preventing a large amount of silicone glue from adhering to the liquid level sensor 311 and not affecting the internal structure of the mounting box 307.

[0031] In addition, the bottom of the inner spline cylinder 403 is open, and the inner side of the inner spline cylinder 403 is connected to the outer spline shaft 405, so that the reciprocating screw 2 can be connected to the inner spline cylinder 403 through the outer spline shaft 405. The inner spline cylinder 403 can limit its movement and keep it in a relatively stable vertical state. The cleaning component 300 can be cleaned by opening the cylinder cover 401. Since they are all plate-shaped or sheet-shaped structures, the adhesion depth and area of ​​silicone sealant can be reduced, making the cleaning of the cleaning component 300 relatively easy, or the inside of the barrel body 1 can be deeply rinsed and cleaned.

[0032] The working principle of the above embodiments is as follows:

[0033] When cleaning the barrel body 1 containing silicone sealant, the servo motor 308 is started, driving the drive gear 309 to rotate, causing the driven gear 310 to rotate, and the reciprocating cylinder 301 to move downward outside the reciprocating screw 2. The connecting rod 302 drives the annular frame 303 to move downward. Under the spiral downward scraping action of the inclined scraper 306, the silicone sealant on the inner wall of the barrel body 1 can be effectively scraped off. Under the annular scraping action of the annular scraper 304, the silicone sealant missed by the inclined scraper 306 can be further scraped off. Thus, the silicone sealant attached to the inner wall of the barrel body 1 can be effectively scraped off and accumulated at the bottom of the barrel body 1, and discharged through the discharge pipe 406.

[0034] Compared with existing technologies, this silicone sealant production cylinder cleaning device effectively cleans the cylinder containing silicone sealant through the coordinated use of the reciprocating screw 2 on the inner side of the cylinder body 1 and the cleaning component 300. The circular scraping action effectively removes the silicone sealant from the inner wall of the cylinder, and the circular scraper structure further scrapes away the remaining sealant, achieving a comprehensive and effective cleaning effect. It also easily cleans structures with attached silicone sealant, greatly reducing the difficulty of cleaning and improving the practicality of the silicone sealant production cylinder cleaning device. This solves the problem that existing silicone sealant production cylinder cleaning devices, when using brushes for cleaning, easily cause sticky silicone sealant to adhere to the outside and inside, affecting the cleaning effect.
