Description

Technical Field

[0001] This utility model relates to the technical field of tape coating, and in particular to a coating device for tape backing. Background Technology

[0002] In tape processing, a coating device is used to apply adhesive to the tape backing. A current tape production coating device (publication number: CN219723564U) operates via a first motor that drives a threaded rod to rotate. A first slider and a second slider are connected by threads along the outer edge of the threaded rod. The rotation of the threaded rod simultaneously moves the first and second sliders. The threads on the inner walls of the first and second sliders are in opposite directions, causing them to move closer together. A first guide roller and a second guide roller are rotatably connected to the inner walls of the first and second sliders, respectively, allowing adjustment of the distance between them. This facilitates limiting and guiding the coating of different thicknesses, improving the device's working efficiency.

[0003] Although adhesive tape can be used for coating, the excess adhesive on the tape is not easily recycled after scraping it off with a scraper, resulting in unnecessary waste of adhesive. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a coating device for adhesive tape backing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A coating device for adhesive tape backing includes a housing, a coating roller rotatably connected to the housing, a scraper connected to the housing, a filter plate installed on the scraper, a frame provided in the housing, a first roller rotatably connected to one end and the other end of the housing, two sets of second rollers rotatably connected to the frame, the two sets of second rollers respectively fitting into contact with corresponding first rollers, and spring telescopic rods connected to the four corners of the housing, with multiple sets of spring telescopic rods connected to the frame.

[0007] Preferably, a crank is rotatably connected to the housing, and the crank is rotatably connected to a rod body via a connecting shaft, the rod body being slidably connected to the frame.

[0008] Preferably, a motor is installed in the housing, and the output end of the motor is connected to the coating roller.

[0009] Preferably, both the coating roller and the corresponding first roller body are connected to grooved wheels, and the two sets of grooved wheels are driven by belts.

[0010] Preferably, a valve body is connected to the housing.

[0011] Preferably, a handle is connected to the crank.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Through the coordination between the set box, coating roller, scraper and filter screen, when the coating roller applies the glue in the box to the tape backing cloth, the scraper can scrape off the excess glue on the tape backing cloth, and at the same time scrape off the glue part on the roller that has come into contact with the tape backing cloth. The glue falling from these two places will pass through the filter screen at the scraper for solid-liquid separation, which prevents the impurities carried on the tape from mixing with the scraped glue, contaminating the glue in the box and affecting its use. At the same time, the glue can be recycled and reused, which can avoid glue waste.

[0014] 2. By coordinating the frame, spring telescopic rod, second roller, first roller, rod, and curved rod, the entire frame can be lifted by using the curved rod to drive the rod to slide at the frame. This facilitates the separation of the second roller from the first roller and makes it easy to place the tape liner between the second roller and the first roller, making installation relatively simple.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figures 1 to 5 A coating device for adhesive tape backing includes a housing 1, the interior of which holds adhesive. A coating roller 2 is rotatably connected to the housing 1. When the coating roller 2 rotates, it carries the adhesive from the housing 1 and coats it onto the adhesive tape backing. A scraper 3 is connected to the housing 1, and a filter plate 4 is installed on the scraper 3. A frame 5 is provided at the housing 1. A first roller 6 is rotatably connected to one end and the other end of the housing 1. When the coating roller 2 coats the adhesive tape backing, one end of the scraper 3 can lift the adhesive tape backing. While scraping off excess glue, the glue on the coating roller 2 can also be scraped off and filtered through the filter plate 4 at the scraper 3, flowing back into the box 1 for collection and reuse. Two sets of second rollers 8 are rotatably connected to the frame 5, and the two sets of second rollers 8 are respectively attached to the corresponding first rollers 6. Spring telescopic rods 7 are connected to the four corners of the box 1. The spring telescopic rods 7 provide the force for the first rollers 6 and second rollers 8 to adhere. Multiple sets of spring telescopic rods 7 are connected to the frame 5.

[0023] In this embodiment, a crank 14 is rotatably connected to the housing 1, and a rod 13 is rotatably connected to the crank 14 via a connecting shaft. The rod 13 is slidably connected to the frame 5. When the crank 14 drives the rod 13 to move, the rod 13 can lift the frame 5, so that the first roller 6 and the second roller 8 can be de-attached, facilitating the installation of the adhesive tape backing. A motor 9 is installed in the housing 1. The model of the motor 9 is selected according to the actual working requirements. The output end of the motor 9 is connected to the coating roller 2. The coating roller 2 and the corresponding first roller 6 are both connected to grooved wheels 10. The two sets of grooved wheels 10 are driven by a belt 11, so that the coating roller 2 and a set of first rollers 6 can rotate synchronously, thereby conveying the adhesive tape backing. A valve body 12 is connected to the housing 1, and the valve body 12 is used to discharge the glue in the housing 1. A handle 15 is connected to the crank 14.

[0024] The working principle of this embodiment is as follows: When in use, the glue is placed in the box 1. After placement, the handle 15 is held to drive the crank 14 to rotate. When the rod 13 slides at the frame 5, the frame 5 can be lifted. At this time, the tape liner passes between multiple sets of first rollers 6 and second rollers 8 and comes into contact with the scraper 3 and coating roller 2. After contact, the first rollers 6 and second rollers 8 can clamp and transport the tape liner using the spring telescopic rod 7. The motor 9 is connected to an external power supply and drive device. The motor 9 will drive the transmission of two sets of grooved pulleys 10 and belts 11, rotating one set of first rollers 6 and coating roller 2. The tape liner can then be transported. The coating roller 2 can then carry the glue in the box 1 to coat the tape liner. The scraper 3 will scrape off the residual glue on the coating roller 2 and the excess glue on the tape liner. The glue will fall at the scraper 3 and pass through the filter plate 4 for solid-liquid separation, and then flow back into the box 1 for recycling.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
