Description

Technical Field

[0001] This utility model relates to the field of latex paint processing technology, and in particular to a latex paint mixing device. Background Technology

[0002] During the mixing of latex paint, a large amount of latex paint easily adheres to the surfaces of the agitator and drive shaft. Traditional cleaning methods require manual removal of the residual paint with tools after the machine is stopped. This is not only time-consuming and labor-intensive, but also results in some paint falling onto the ground or into equipment gaps, causing material waste and environmental pollution. In addition, if the residual paint is not cleaned in time, it can easily dry and harden on the equipment surface, affecting the subsequent mixing effect and increasing the motor load. Utility Model Content

[0003] The purpose of this invention is to provide a latex paint mixing device that solves the problem that traditional cleaning methods require manual shutdown and scraping of residual paint with tools, which is time-consuming and labor-intensive.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a latex paint mixing device, comprising a mixing tank, a lifting platform, an extension shaft mounted on the lifting platform, a mixing motor mounted at the front end of the extension shaft, a transmission shaft mounted on the mixing motor, and a stirrer mounted at the front end of the transmission shaft. The front end of the extension shaft is further provided with a guide plate, and a tank cover is provided below the guide plate. A guide post is provided on the tank cover, and the guide post is slidably connected to the guide plate. A mixing hole is provided at the center of the tank cover. The stirrer extends into the mixing tank through the mixing hole. A first scraper is provided below the mixing hole. The first scraper has a scraping hole coaxial with the mixing hole, and the scraping hole has the same diameter as the transmission shaft. A degumming baffle is provided on the outer side of the scraper, and a second scraper is provided inside the degumming baffle. The second scraper is slidably connected to the interior of the degumming baffle.

[0005] Furthermore, the first scraper includes a conical support cover with its top facing downwards and a conical guide cover with its top facing upwards located at the bottom of the conical support cover. An observation hole is provided on the circumferential surface of the conical support cover, and the scraper hole penetrates through the conical support cover and the conical guide cover.

[0006] Furthermore, the bottom end of the degumming baffle is lower than the bottom end of the conical guide cap.

[0007] Furthermore, the second scraper includes an annular scraper, a transmission rod, a guide plate, and a drive cylinder. The annular scraper is disposed on the inner wall of the degumming baffle and fits against the inner wall. The transmission rod is connected to the annular scraper and extends upward toward the bucket lid. The guide plate is slidably connected to the guide post. The drive cylinder is disposed on the bucket lid and located below the guide plate. The transmission rod is fixedly connected to the guide plate. The guide plate drives the transmission rod and the annular scraper to slide up and down.

[0008] Furthermore, a limiting bracket is provided above the bucket lid on the outer periphery of the stirring hole, and the limiting bracket is higher than the highest sliding point of the guide slide plate.

[0009] Furthermore, the diameter of the limiting bracket is the same as the diameter of the stirring motor, and the upper end of the limiting bracket is chamfered.

[0010] Furthermore, a limiting plate is provided at the bottom of the guide post.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Specifically, the relative motion difference created by the delayed ascent of the bucket lid due to its own weight allows the first scraper to actively scrape the surface of the transmission column during the initial rising phase of the agitator, effectively peeling off the attached latex paint. When the agitator rises into the delamination baffle, it is driven to rotate again, and the centrifugal force throws the latex paint on the agitator onto the delamination baffle. The second scraper inside the delamination baffle then cleans the latex paint inside the baffle, forming a dual cleaning mechanism of "throwing away + scraping off". This achieves the cleaning of residual latex paint on the transmission column and agitator surface. During the cleaning process, the peeled paint naturally falls back into the mixing bucket along the guide of the first and second scrapers. This avoids the material waste caused by traditional manual scraping, maintains the cleanliness of the equipment through a mechanical self-cleaning mechanism, reduces the operating resistance of the transmission system, and reduces equipment wear caused by paint curing, thus extending the overall maintenance cycle.

[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. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0020] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0021] like Figures 1 to 4As shown, this utility model provides a latex paint mixing device, including a mixing tank 1, a lifting platform 11, an extension shaft 12 mounted on the lifting platform 11, a mixing motor 13 mounted at the front end of the extension shaft 12, a transmission shaft 14 mounted on the mixing motor 13, and a stirrer 15 mounted at the front end of the transmission shaft 14. The structure and installation method of the mixing tank 1, lifting platform 11, mixing motor 13, transmission shaft 14, and stirrer 15 are all conventional equipment and methods in the field of building material raw material production, and will not be described in detail here. The main feature is that a steel circular guide plate 2 is mounted on the extension shaft. The guide plate 2 is sleeved on the mixing motor 13. The guide plate 2 is the same size as the mixing tank 1. Four mutually symmetrical mounting holes are opened on the guide plate 2, and guide posts 21 are installed in each of the four mounting holes. A tank cover 3 is installed at the bottom of the guide posts 21, realizing... The lid 3 is connected to the extension shaft and can slide on the guide post 21. The lid 3 is used to cover the mixing tank 1 during the production of latex paint to prevent debris from falling into the mixing tank 1. A stirring hole 31 is provided at the center of the lid 3. The diameter of the stirring hole 31 is larger than the diameter of the agitator 15, so that the agitator 15 can be inserted into the mixing tank 1 through the stirring hole 31. A first scraper 32 is provided on the bottom surface of the lid 3. The first scraper 32 is coaxial with the stirring hole 31. The first scraper 32 has a scraping hole 33 coaxial with the stirring hole 31. The scraping hole 33 has the same diameter as the drive shaft 14 of the agitator 15. A degumming baffle 34 is provided on the outside of the scraper. The degumming baffle 34 is a cylindrical baffle. A second scraper 4 is provided inside the degumming baffle 34. The second scraper 4 is slidably connected to the inside of the degumming baffle 34.

[0022] Specifically, when the elevator 11 descends, the lid 3 first covers the mixing tank 1. The elevator 11 continues to descend, and the agitator 15 extends into the mixing tank 1 through the mixing hole 31. The agitator 15 is driven to rotate by the mixing motor 13 to achieve mixing. After mixing is completed, the elevator 11 rises, driving the mixing motor 13 and the agitator 15 to rise synchronously. At this time, the lid 3 will rise with a delay due to its own weight. The agitator 15 and the mixing motor 13 rise first. During the rising process, the first scraper 32 actively scrapes the surface of the transmission column during the initial rising stage of the agitator 15, cleaning the latex paint adhering to the transmission column. When the agitator 15 rises into the degumming baffle 34, the agitator 15 is driven to rotate again. Centrifugal force throws the latex paint on the agitator 15 onto the degumming baffle 34. Plate 34 prevents latex paint from being flung onto the inner wall of the mixing tank 1 when the agitator 15 rotates. The inner wall of the mixing tank 1 is relatively large, and the paint still flows down the tank wall when scraping, making cleaning more difficult. This utility model uses a second scraper 4 inside the degumming baffle 34 to clean the latex paint inside the degumming baffle 34, forming a dual cleaning mechanism of "flickering + scraping". This achieves the cleaning of residual latex paint on the transmission column and the surface of the agitator 15. During the cleaning process, the peeled paint naturally falls back into the mixing tank 1 along the guide of the first scraper 32 and the second scraper 4. This not only avoids the material waste caused by traditional manual scraping, but also maintains the cleanliness of the equipment through a mechanical self-cleaning mechanism, reduces the operating resistance of the transmission system, and reduces equipment wear caused by paint curing, thus extending the overall maintenance cycle.

[0023] To prevent adhesive from adhering to the upper wall of the bucket lid 3 during the scraping of the drive shaft, the first scraper 32 includes a conical support cover 321 with its top facing downwards and a conical guide cover 322 with its top facing upwards located at the bottom of the conical support cover 321. An observation hole 323 is provided on the circumferential surface of the conical support cover 321, and the scraping hole 33 penetrates through the conical support cover 321 and the conical guide cover 322. Specifically, the conical support cover 321 with its top facing downwards is used for support, and the scraping hole 33 is located at the center of the conical support cover 321, allowing for proper scraping of the drive shaft 14. The position of the cone support cover 321 is not on the same plane as the upper surface of the lid 3, which can effectively prevent the glue from adhering to the upper surface of the lid 3. At the same time, in order to speed up the dripping of the glue after cleaning, a cone-shaped guide cover 322 with the top facing upward is set below the cone-shaped support cover 321. When scraping the glue on the drive shaft 14, the top space of the cone-shaped guide cover 322 is small, which has a good effect on the gathering of glue. The gathered glue has a larger self-weight, making it easier to drip. At the same time, an observation hole 323 is also provided on the circumference of the cone support cover 321, which allows the staff to directly observe the state of the glue in the mixing tank 1.

[0024] The bottom of the degumming baffle 34 is lower than the bottom of the conical guide cover 322; specifically, it ensures that the agitator 15 is inside the degumming baffle 34 when it is close to the conical guide cover 322, so as to prevent the glue from being splashed into the tank wall of the mixing tank 1 when cleaning the glue.

[0025] To accelerate the dripping of adhesive from the inner wall of the degumming baffle 34, a second scraper 4 is provided inside the degumming baffle 34. The second scraper includes an annular scraper 41, a transmission rod 42, a guide slide plate 43, and a drive cylinder 44. The annular scraper 41 is disposed on and adheres to the inner wall of the degumming baffle 34. The transmission rod 42 is connected to the annular scraper 41 and extends upward toward the bucket lid 3. The guide slide plate 43 is slidably connected to the guide post 21. The drive cylinder 44 is disposed on the bucket lid 3 and located below the guide slide plate 43. The transmission rod 42 is fixedly connected to the guide slide plate 43. The guide slide plate 43 drives the transmission rod 42 and the annular scraper 41 to slide up and down. Specifically, the guide slide plate 43 and the transmission rod 42 are driven by the drive cylinder 44, so that the annular scraper 41 can move from the top of the degumming baffle 34 to the bottom of the degumming baffle 34. During the sliding, the inner wall of the degumming baffle 34 is cleaned, which accelerates the dripping of glue and paint inside the degumming baffle 34. At the same time, the guide slide plate 43 installed on the guide post 21 can improve the stability of the movement of the annular scraper 41.

[0026] To prevent the stirring motor 13 from interfering with the guide slide plate 43, a limiting bracket 5 is provided on the outer periphery of the stirring hole 31 of the bucket cover 3. The limiting bracket 5 is higher than the highest sliding point of the guide slide plate 43. The diameter of the limiting bracket 5 is the same as the diameter of the stirring motor 13. The upper end of the limiting bracket 5 is provided with a chamfer 51. When the stirring motor 13 descends, it will abut against the limiting bracket 5. At this time, it can be seen that the stirrer 15 is already at the bottom of the stirring bucket 1, and the elevator 11 will no longer descend. The chamfer 51 at the top of the limiting bracket 5 is to achieve surface contact with the stirring motor 13. Surface contact is smoother than linear contact and causes less damage to the elevator 11.

[0027] In order to enable the lifting platform 11 to lift the bucket lid 3, a limit plate 22 is set at the top of the guide column 21. When the lifting platform 11 rises to the top of the guide column 21, the bucket lid 3 is lifted synchronously by the support of the limit plate 22, thus realizing the mechanical opening of the bucket lid 3 and reducing manual labor.

[0028] In addition to the preferred embodiments described above, the present invention has other embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection claimed by the present invention.
