DETAILED DESCRIPTION

[0023] like Figures 1-6 As shown, the utility model provides a technical solution: a drip-proof glue coating device, comprising a shell 1, a handle 3 is fixedly connected to the bottom surface of the shell 1, a bracket 4 is fixedly connected to the top surface of the shell 1, a rotating shaft 5 passes through and is rotatably connected to the inner side of the bracket 4, a glue coating roller 6 passes through and is fixedly connected to the rotating shaft 5, and a control part 2 for preventing glue from dripping is arranged inside the shell 1, and the control part 2 comprises: an active cavity 21, a U-shaped frame 22, a scraper strip 23, a connecting column 24, a connecting rod 25, an anti-slip plate 26, a spring 27, a pull rod 28, a hinged rod 29, a linkage block 210, a turntable 211, a lever 212, a rotating rod 213, a slide groove rod 214, a lifting column 215, a resistance block 216, a scroll spring 217, a rotating sleeve 218, and an active groove 219.

[0024] The movable cavity 21 is opened on the inner side of the housing 1. The inner side of the movable cavity 21 penetrates and is slidably connected with a U-shaped frame 22. A scraping strip 23 is fixedly connected to the inner side of the U-shaped frame 22. When the linkage block 210 is driven by the lifting column 215 to move downward, it will pull the hinge rod 29, and the hinge rod 29 will abut against the inner side of the movable cavity 21, causing both ends of the hinge rod 29 to rotate to a certain extent and pulling the pull rod 28, so that the pull rod 28 pulls the U-shaped frame 22, and further makes the scraping strip 23 on the inner side of the U-shaped frame 22 fit the surface of the glue applicator roller 6. A pull rod 28 is fixedly connected to the surface of the U-shaped frame 22. One end of the pull rod 28 away from the U-shaped frame 22 penetrates and is hinged with a hinge rod 29. One end of the hinge rod 29 away from the pull rod 28 penetrates and is hinged with a linkage block 210. The lifting column 215 limits the abutting block 216. Then when the chute rod 214 rotates, it will drive the lifting column 215 to move downward through the abutting block 216, and further make the lifting column 215 drive the linkage block 210 to move downward together by a certain distance. When the linkage block 210 is driven by the lifting column 215 to move downward, it will pull the hinge rod 29. A lifting column 215 is fixedly connected to the bottom surface of the linkage block 210. An abutting block 216 is fixedly connected to the inner side of the lifting column 215, and the lifting column 215 penetrates the handle 3 and is slidably connected. A turntable 211 penetrates and is rotatably connected to the inner wall of the handle 3. A rotating rod 213 penetrates the surface of the turntable 211. The rotating rod 213 is fixedly connected to the turntable 211. A chute rod 214 is fixedly connected to the top surface of the turntable 211. The abutting block 216 fixedly connected to the inner side of the lifting column 215 penetrates the chute on the surface of the chute rod 214. When the turntable 211 rotates, it will drive the rotating rod 213 and the chute rod 214 to rotate together. When the rotating rod 213 rotates, it will contract the scroll spring 217. At the same time, when the chute rod 214 rotates, the chute on its surface abuts against the abutting block 216. Since the lifting column 215 penetrates the handle 3 and is slidably connected, the lifting column 215 limits the abutting block 216.

[0025] The surface of the rotating rod 213 is fixedly connected with a volute spring 217. When the U-shaped frame 22 is pulled by the pull rod 28, the connecting column 24 will be driven to move together, thereby compressing the spring 27. After the painting is completed, the rotating sleeve 218 is released, and the contracted volute spring 217 will drive the rotating rod 213 to reverse. At the same time, the compressed spring 27 will also push the connecting column 24 to reset the U-shaped frame 22. The end of the volute spring 217 away from the rotating rod 213 is fixedly connected to the inner wall of the handle 3. The number of the U-shaped frame 22 is two groups, and the two groups of U-shaped frames 22 are symmetrically arranged with the center line of the housing 1 as the symmetry axis. The surface of the U-shaped frame 22 is fixedly connected with a connecting column 24, and the inner side of the connecting column 24 is penetrated and slidably connected with a connecting rod 25. The two ends of the connecting rod 25 respectively penetrate the connecting column 24 symmetrically arranged on the inner side of the U-shaped frame 22, and the two ends of the connecting rod 25 are fixedly connected with an anti-slip plate 26, and a spring 27 is fixedly connected between the anti-slip plate 26 and the inner wall of the connecting column 24. A movable groove 219 is provided on the surface of the handle 3, and a lever 212 is fixedly connected to the side of the turntable 211. A rotating sleeve 218 is fixedly connected to the end of the lever 212 away from the turntable 211. The rotating sleeve 218 is penetrated by the handle 3 and is rotatably connected. One hand grasps the handle 3, and the other hand grasps the rotating sleeve 218 and rotates the rotating sleeve 218, so that the rotating sleeve 218 drives the lever 212 to rotate, and the lever 212 will turn the turntable 211.

[0026] Based on the above embodiment, when in use, the glue coating roller 6 is inserted into the container for storing glue so that the surface of the glue coating roller 6 is fully adhered to the glue. If the glue is too viscous or too much, it may drip during the brushing process. At this time, one hand can grasp the handle 3, and the other hand can grasp the rotating sleeve 218 and rotate the rotating sleeve 218, so that the rotating sleeve 218 drives the lever 212 to rotate, and the lever 212 will toggle the turntable 211. When the turntable 211 rotates, it will drive the rotating rod 213 and the sliding groove rod 214 to rotate together. When the rotating rod 213 rotates, the spiral spring 217 will be contracted. At the same time, when the sliding groove rod 214 rotates, the sliding groove on the surface of the sliding groove rod 214 contacts the contact block 216. Since the lifting column 215 passes through the handle 3 and is slidably connected, the lifting column 215 limits the contact block 216. Then, when the sliding groove rod 214 rotates, the lifting column 215 will be driven to move downward through the contact block 216, and the lifting column 215 further drives the linkage block 2 10 moves downward for a certain distance, and when the linkage block 210 is driven by the lifting column 215 to move downward, the hinged rod 29 is pulled, and the hinged rod 29 contacts the inner side of the active cavity 21, so that both ends of the hinged rod 29 rotate to a certain extent and pull the pull rod 28, so that the pull rod 28 pulls the U-shaped frame 22, and then the scraper 23 on the inner side of the U-shaped frame 22 is attached to the surface of the glue coating roller 6, so that when the glue coating roller 6 pushes the roller brush upward, the scraper 23 located below The glue on the surface of the glue coating roller 6 will be scraped to the inner side of the shell 1 to prevent it from dripping downwards. When the U-shaped frame 22 is pulled by the pull rod 28, the connecting column 24 will be driven to move together, thereby compressing the spring 27. After the coating is completed, the rotating sleeve 218 is released, and the contracted spiral spring 217 will drive the rotating rod 213 to reverse. At the same time, the compressed spring 27 will also push the connecting column 24 to reset the U-shaped frame 22, and then the scraper strip 23 will no longer fit the glue coating roller 6, so that the glue coating roller 6 is easy to clean.

[0027] The glue scraped by the scraper strip 23 above will adhere to the scraper strip 23 to a certain extent. During the coating process of the glue coating roller 6, the glue on the surface is reduced, and the glue attached to the scraper strip 23 above the glue coating roller 6 and the glue scraped to the inside of the shell 1 can replenish the glue on the surface of the glue coating roller 6 to a certain extent, avoiding waste.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
