An adjustable gap paint surface roller pressure equalization structure

Abstract

This utility model discloses an adjustable gap roller pressure equalization structure for paint coating, relating to the field of paint coating technology. It includes a roller brush mechanism comprising a mirror roller and a coating roller. The utility model uses a movable base to drive an electric telescopic rod, thereby adjusting the distance between the mirror roller and the coating roller. In this way, when cleaning the area between the coating roller and the mirror roller, the mirror roller can squeeze the coating sleeve, preventing water from flowing out and facilitating surface cleaning. A limiting baffle can partially block the water flow, reducing its speed and facilitating cleaning. Subsequently, the mirror roller can be moved away from the coating sleeve to quickly expel the water. Simultaneously, because the distance is adjustable, a hand can be inserted between the mirror roller and the coating sleeve for cleaning, eliminating the need to drive the coating roller to rotate for cleaning. This makes it more convenient to use, reduces energy consumption, and avoids the need for excessive force to rotate the coating roller, reducing cleaning difficulty.

Description

Technical Field

[0001] This utility model relates to the field of paint application technology, and in particular to a roller pressure equalization structure for paint surfaces with adjustable gap. Background Technology

[0002] Paint is a chemical mixture that can firmly cover the surface of an object, serving protective, decorative, marking, and other special purposes. It is named after the fact that people initially used vegetable oil as the main raw material for paint production. Paint generally consists of four parts: film-forming substances, fillers (pigments and fillers), solvents, and additives. The composition may vary slightly depending on performance requirements; for example, varnishes do not contain pigments and fillers, and powder coatings may not contain solvents. The application methods for paint also vary depending on the application scenario, with spraying and brushing being the most common methods.

[0003] In existing technologies, paint application is mostly done using brush rollers, which are then applied by a roller coating machine. However, the distance between the brush roller and the mirror roller in the roller coating machine is fixed and cannot be adjusted. This makes it inconvenient to clean the connection between the mirror roller and the brush roller after use, and it is also inconvenient to discharge the wastewater generated during cleaning. Utility Model Content

[0004] The purpose of this invention is to solve the problem that in the existing technology, paint brushing is mostly done using a brush roller, which is then processed by a roller coating machine. However, the distance between the brush roller and the mirror roller in the roller coating machine is fixed and cannot be adjusted. This makes it inconvenient to clean the connection between the mirror roller and the brush roller after use, and it is also inconvenient to discharge the wastewater generated during cleaning. Therefore, this invention proposes a paint roller pressure equalization structure with adjustable gap.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable gap paint roller pressure equalization structure, comprising a roller brush mechanism, the roller brush mechanism comprising a mirror roller and a coating roller, both ends of the mirror roller and the coating roller being provided with side frames, the shaft of the coating roller being rotatably connected to the side frame, a first groove being opened on one side of the side frame, a movable seat being slidably connected inside the first groove, the shaft of the mirror roller being rotatably connected to the movable seat, a side plate being fixedly connected to one side of the side frame, the middle of the side plate being used to install an electric telescopic rod, an installation sleeve being fixedly connected to the middle of one side of the movable seat, the output end of the electric telescopic rod being fixedly connected to the installation sleeve, a first gear being fixedly connected to the shaft of the coating roller, a second gear being fixedly connected to the shaft of the mirror roller, limiting baffles being fixedly connected to both ends of the mirror roller, a third gear meshing on the outer surfaces of the first gear and the second gear, the two third gears meshing with each other, and a coating sleeve being fixedly connected to the outer surface of the coating roller.

[0006] Preferably, a movable frame is fixedly connected to the middle of the side frame, and a second sliding groove is opened inside the movable frame, with a first sliding frame slidably connected inside the second sliding groove.

[0007] Preferably, the first sliding frame has a third sliding groove inside, and the second sliding frame is slidably connected inside the third sliding groove.

[0008] Preferably, one end of the second sliding frame is fixedly connected to an inner plate, and the third gear is rotatably connected to the inner plate.

[0009] Preferably, a No. 1 slot is provided at the lower end of both the No. 2 sliding frame and the No. 3 sliding groove, and a spring is fixedly connected between the upper and lower No. 1 slots.

[0010] Preferably, a cleaning mechanism is provided between the two side frames. The cleaning mechanism includes a cleaning frame, a scraping frame is slidably connected inside the cleaning frame, and a fastening magnet is fixedly connected to the middle of one end of the scraping frame.

[0011] Preferably, a second slot is provided in the middle of the cleaning frame, and an electromagnet is fixedly connected inside the second slot. Rubber teeth are fixedly connected to both sides of the middle of one side of the scraping frame. The rubber teeth are parallel to the coating roller, and the rubber teeth on both sides of the scraping frame are staggered.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, the movable seat drives the electric telescopic rod to adjust the distance between the mirror roller and the coating roller. In this way, when cleaning the area between the coating sleeve and the mirror roller, the mirror roller can be squeezed to prevent water from flowing out, thus facilitating surface cleaning. The limiting baffle can partially block the water flow, reducing the speed of water flow and making cleaning easier. Subsequently, the mirror roller can be moved away from the coating sleeve to quickly discharge the water. At the same time, because the distance is adjustable, the hand can be inserted into the area between the mirror roller and the coating sleeve for cleaning, thus eliminating the need to drive the coating roller to rotate for cleaning. This makes it more convenient to use, reduces energy consumption, and avoids the need for large-force rotation of the coating roller, reducing the difficulty of cleaning.

[0014] 2. In this utility model, the inner plate and side frame, along with springs, ensure that the No. 3 gear is always engaged with the No. 1 and No. 2 gears by the pull of the springs when the mirror roller moves, thus ensuring transmission stability. This method is infinitely adjustable to any distance, and its simple structure and low manufacturing cost make it convenient to use. The scraper and rubber teeth scrape the surface of the coating sleeve to prevent paint from clumping. After roller brushing, the paint deep within the coating sleeve can still be squeezed to prevent clumping and ensure uniform roller pressure. The electromagnet allows the scraper to be pushed to squeeze the coating sleeve or retracted into the cleaning frame by controlling the electrode direction and magnetic attraction. This makes it convenient to use and allows for adjustable squeezing force. Attached Figure Description

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1-6As shown, this utility model provides a roller pressure equalization structure for an adjustable gap paint surface, including a roller brush mechanism. The roller brush mechanism includes a mirror roller 1 and a coating roller 2. Both the mirror roller 1 and the coating roller 2 have side frames 4 at their ends. The shaft of the coating roller 2 is rotatably connected to the side frame 4. A first groove 12 is formed on one side of the side frame 4. A movable seat 13 is slidably connected inside the first groove 12. The shaft of the mirror roller 1 is rotatably connected to the movable seat 13. A side plate 14 is fixedly connected to one side of the side frame 4. The middle of the side plate 14 is... For the installation of the electric telescopic rod, a mounting sleeve 15 is fixedly connected to the middle of one side of the movable seat 13. The output end of the electric telescopic rod is fixedly connected to the mounting sleeve 15. A first gear 6 is fixedly connected to the shaft of the coating roller 2. A second gear 11 is fixedly connected to the shaft of the mirror roller 1. Restriction baffles 5 are fixedly connected to both ends of the mirror roller 1. A third gear 23 meshes with the outer surfaces of the first gear 6 and the second gear 11. The two third gears 23 mesh with each other. A coating sleeve 3 is fixedly connected to the outer surface of the coating roller 2.

[0025] The specific settings and functions of this embodiment are described in detail below. The movable seat 13 drives the electric telescopic rod to adjust the distance between the mirror roller 1 and the coating roller 2. In this way, when cleaning the area between the coating sleeve 3 and the mirror roller 1, the mirror roller 1 can be pressed against the coating sleeve 3 to prevent water from flowing out, thus facilitating surface cleaning. The limiting baffle 5 can partially block the water flow, reducing the speed of water flow and facilitating cleaning. Subsequently, the mirror roller 1 can be moved away from the coating sleeve 3 to quickly discharge the water. At the same time, because the distance is adjustable, the hand can be inserted into the area between the mirror roller 1 and the coating sleeve 3 for cleaning, thus eliminating the need to drive the coating roller 2 to rotate for cleaning. This makes it more convenient to use, reduces energy consumption, and avoids the need for large-force rotation of the coating roller 2, reducing the difficulty of cleaning.

[0026] Example 2: Figures 1-6As shown, a movable frame 7 is fixedly connected to the middle of the side frame 4. A second sliding groove 16 is provided inside the movable frame 7. A first sliding frame 17 is slidably connected inside the second sliding groove 16. A third sliding groove 18 is provided inside the first sliding frame 17. A second sliding frame 24 is slidably connected inside the third sliding groove 18. An inner plate 8 is fixedly connected to one end of the second sliding frame 24. A third gear 23 is rotatably connected to the inner plate 8. A first locking slot 19 is provided at the lower ends of both the second sliding frame 24 and the third sliding groove 18. The two first locking slots 19 are connected... A spring is fixedly connected between the two side frames 4. A cleaning mechanism is provided between the two side frames 4. The cleaning mechanism includes a cleaning frame 9. A scraping frame 21 is slidably connected inside the cleaning frame 9. A fastening magnet 22 is fixedly connected to the middle of one end of the scraping frame 21. A second slot 20 is opened in the middle of the cleaning frame 9. An electromagnet 10 is fixedly connected inside the second slot 20. Rubber teeth 25 are fixedly connected to both sides of the middle of one side of the scraping frame 21. The rubber teeth 25 are parallel to the brush roller 2. The rubber teeth 25 on both sides of the scraping frame 21 are staggered.

[0027] The overall effect of this embodiment is that, through the setting of the inner plate 8 and the side frame 4, and in conjunction with the spring, the third gear 23 is always engaged with the first gear 6 and the second gear 11 by the pull of the spring when the mirror roller 1 moves, so as to ensure transmission stability. At the same time, this method can be infinitely adjusted to any distance. Moreover, this method has a simple structure, low manufacturing cost, and is easy to use. The scraping frame 21 and the rubber teeth 25 are used to scrape the surface of the coating sleeve 3 to avoid the paint from clumping on the surface of the coating sleeve 3. After the roller brushing, the paint deep in the coating sleeve 3 can still be squeezed to prevent clumping and ensure the uniformity of roller pressure. Through the setting of the electromagnet 10, the scraping frame 21 can be pushed to squeeze the coating sleeve 3 or put into the cleaning frame 9 by controlling the direction of the electrode and the magnetic attraction of the electrode. It is easy to use and the squeezing force is adjustable.

[0028] The usage and working principle of this device are as follows: During roller brush processing, the distance between the mirror roller 1 and the coating sleeve 3 is adjusted according to the roller brush requirements. The coating sleeve 3 then performs roller brush processing on the surface of the workpiece. During this process, the current of the electromagnet 10 is adjusted according to the processing parameters to adjust the magnetism. The direction of the magnetic poles is adjusted according to the current direction to move the scraping frame 21 toward the coating sleeve 3, causing the rubber teeth 25 to squeeze the coating sleeve 3 and scrape the surface of the coating sleeve 3. When cleaning is required, the mirror roller 1 is moved to the end according to the brushing requirements, leaving a large gap between it and the coating sleeve 3. The surfaces of the coating sleeve 3 and the mirror roller 1 are then cleaned. Alternatively, the mirror roller 1 can be pressed tightly against the coating sleeve 3 so that water flows between the mirror roller 1 and the coating sleeve 3 to facilitate deep brushing of the surface of the coating sleeve 3.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
