Description

Technical Field

[0001] This utility model relates to the field of adhesive tape residue scraping technology, and in particular to an adhesive residue scraping mechanism. Background Technology

[0002] Adhesive tape consists of two parts: a substrate and an adhesive. After the tape is processed and formed, the substrate coated with adhesive is compressed into a roll one by one. During this process, some of the adhesive on the substrate is squeezed out and solidifies at both ends of the formed roll. Since the residual adhesive on the end face of the roll will affect the use of the tape, it needs to be scraped off.

[0003] A search revealed patent CN219442589U, which discloses "a device for scraping off residual adhesive from adhesive tape." The device includes a frame, a scraping assembly, and a clamping assembly. The scraping assembly comprises a crossbar and two scrapers. The crossbar is horizontally positioned, with both ends of its long side connected to the frame. The two scrapers are respectively positioned at both ends of the long side of the crossbar, with their blades facing each other and capable of contacting the end face of the film roll. The scrapers are connected to the crossbar. The clamping assembly is connected to the frame and is used to clamp the film roll. This device uses the clamping assembly to hold and fix the film roll, ensuring the scraper blades contact the end face of the film roll. External force drives the film roll to rotate, causing the scrapers to simultaneously scrape off residual adhesive from both ends of the film roll, thereby improving work efficiency.

[0004] Existing technology uses a squeegee to scrape off excess adhesive from the end face of the film roll by rotating the roll. However, there is a lot of adhesive between the tapes during the rolling process, and if the tape is continued to be squeezed after rolling, the excess adhesive between the tapes will continue to flow out to the end face, requiring the squeegee to scrape it off multiple times, which can easily damage the tape and is inconvenient to use. Summary of the Invention

[0005] The purpose of this invention is to provide a residual adhesive scraping mechanism that greatly reduces the frequency of scraper use, reduces damage to the tape caused by the scraper, avoids incomplete adhesive removal, and improves adhesive removal efficiency.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a residual adhesive scraping mechanism, comprising: a mounting frame, a movable plate located below the mounting frame, and two scrapers arranged opposite each other at the bottom of the movable plate, and a plurality of electric telescopic rods arranged between the top of the movable plate and the top of the mounting frame;

[0007] A first guide rod and a second guide rod are rotatably connected to the moving plate on opposite sides of the two scrapers, and an elastic element is provided between the first guide rod and the second guide rod. A first extrusion roller is rotatably installed between the two first guide rods, and a second extrusion roller is rotatably installed between the two second guide rods. The first extrusion roller and the second extrusion roller are arranged in parallel. When the first extrusion roller and the second extrusion roller move in opposite directions, the elastic element is in an extended state.

[0008] The following are further improvements to the above technical solution:

[0009] 1. In the above scheme, a sliding groove is respectively opened on the two inner walls opposite to the mounting bracket, and a slider that is slidably connected to the sliding groove is fixedly installed at the end of the movable plate.

[0010] 2. In the above scheme, the electric telescopic rod is fixedly installed on the top of the mounting frame.

[0011] 3. In the above scheme, the first guide rod and the second guide rod are rotatably mounted on the fixed block at the bottom of the movable plate.

[0012] 4. In the above scheme, a threaded rod is installed on the top of the scraper, and the threaded rod is threadedly connected to the moving plate.

[0013] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0014] This utility model relates to a residual adhesive scraping mechanism. A movable plate is positioned below a mounting frame, with two scrapers positioned opposite each other at the bottom of the movable plate. Several electrically operated telescopic rods are located between the top of the movable plate and the top of the mounting frame. A first guide rod and a second guide rod are rotatably connected to the movable plate on opposite sides of the two scrapers. An elastic element is positioned between the first and second guide rods. A first extrusion roller is rotatably mounted between the two first guide rods, and a second extrusion roller is rotatably mounted between the two second guide rods. The movable plate is driven downwards by the electrically operated telescopic rods, causing the first and second extrusion rollers to move opposite each other along the surface of the roll material to be processed. Under the tension of the elastic element, the first and second extrusion rollers maintain close contact with the roll material, thus facilitating the extrusion of excess adhesive from inside the roll material. This excess adhesive is then scraped away by the scrapers. This achieves complete removal of excess adhesive from the tape in a single scraping operation, significantly reducing the frequency of scraper use, minimizing damage to the tape, preventing incomplete adhesive removal, and improving adhesive removal efficiency.

[0019] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0020] Example 1: A residual adhesive scraping mechanism includes: a mounting frame 1, a movable plate 5 located below the mounting frame 1, and two scrapers 7 arranged opposite each other at the bottom of the movable plate 5. A plurality of electric telescopic rods 2 are arranged between the top of the movable plate 5 and the top of the mounting frame 1. The height of the scrapers is adjusted by threaded rods, and then the electric telescopic rods are controlled to drive the movable plate to move. The movable plate moves along the slide groove of the mounting frame by a slider.

[0021] A first guide rod 8 and a second guide rod 9 are rotatably connected to the moving plate 5 on opposite sides of the two scrapers 7, and an elastic element 11 is provided between the first guide rod 8 and the second guide rod 9. A first extrusion roller 12 is rotatably installed between the two first guide rods 8 and a second extrusion roller 13 is rotatably installed between the two second guide rods 9. The first extrusion roller 12 and the second extrusion roller 13 are arranged in parallel. When the first extrusion roller 12 and the second extrusion roller 13 move in opposite directions, the elastic element 11 is in an extended state.

[0022] During the movement of the moving plate, the first and second extrusion rollers at the bottom of the moving plate come into contact with the surface of the tape. As the moving plate moves downward, the first and second extrusion rollers roll along the surface of the tape and cause the first and second guide rods to unfold, while stretching the elastic element. At this time, under the elastic force of the elastic element, the first and second guide rods are driven to move closer to each other, so that the first and second extrusion rollers squeeze the tape and squeeze out the excess adhesive from both ends of the tape. Then, the residual adhesive at both ends of the tape is scraped off by a scraper.

[0023] A sliding groove 3 is provided on each of the two inner walls opposite to the mounting bracket 1, and a slider 4 that is slidably connected to the sliding groove 3 is fixedly installed at the end of the movable plate 5.

[0024] The aforementioned electric telescopic pole 2 is fixedly installed on the top of the mounting bracket 1.

[0025] The first guide rod 8 and the second guide rod 9 are each rotatably mounted on the fixed block 10 at the bottom of the movable plate 5.

[0026] A threaded rod 6 is installed on the top of the scraper 7, and the threaded rod 6 is threadedly connected to the movable plate 5.

[0027] Example 2: A residual adhesive scraping mechanism, comprising: a mounting frame 1, a movable plate 5 located below the mounting frame 1, and two scrapers 7 arranged opposite each other at the bottom of the movable plate 5, and a plurality of electric telescopic rods 2 arranged between the top of the movable plate 5 and the top of the mounting frame 1;

[0028] A first guide rod 8 and a second guide rod 9 are rotatably connected to the moving plate 5 on opposite sides of the two scrapers 7, and an elastic element 11 is provided between the first guide rod 8 and the second guide rod 9. A first extrusion roller 12 is rotatably installed between the two first guide rods 8 and a second extrusion roller 13 is rotatably installed between the two second guide rods 9. The first extrusion roller 12 and the second extrusion roller 13 are arranged in parallel. When the first extrusion roller 12 and the second extrusion roller 13 move in opposite directions, the elastic element 11 is in an extended state.

[0029] The moving plate is driven downward by an electric telescopic rod, causing the first and second extrusion rollers to move in opposite directions along the surface of the roll to be processed. Under the tension of the elastic element, the first and second extrusion rollers maintain close contact with the roll, which helps to squeeze out excess adhesive from inside the roll. The excess adhesive is then scraped off by a scraper, achieving complete removal of excess adhesive between the tapes in a single scraping process. This greatly reduces the frequency of scraper use, reduces damage to the tape, avoids incomplete adhesive removal, and improves adhesive removal efficiency.

[0030] A sliding groove 3 is provided on each of the two inner walls opposite to the mounting bracket 1, and a slider 4 that is slidably connected to the sliding groove 3 is fixedly installed at the end of the movable plate 5.

[0031] The aforementioned electric telescopic pole 2 is fixedly installed on the top of the mounting bracket 1.

[0032] The first guide rod 8 and the second guide rod 9 are each rotatably mounted on the fixed block 10 at the bottom of the movable plate 5.

[0033] The working principle is as follows:

[0034] In use, the height of the scraper is adjusted by the threaded rod, and then the electric telescopic rod is controlled to move the moving plate. The moving plate moves along the slide groove of the mounting frame via the slider. During the movement of the moving plate, the first and second extrusion rollers at the bottom of the moving plate contact the surface of the tape. As the moving plate moves down, the first and second extrusion rollers roll along the surface of the tape and cause the first and second guide rods to unfold, while stretching the elastic element. At this time, under the elastic force of the elastic element, the first and second guide rods are driven to move closer to each other, so that the first and second extrusion rollers squeeze the tape and squeeze out the excess adhesive from both ends of the tape. Then, the scraper removes the residual adhesive from both ends of the tape.

[0035] When the above-mentioned residual adhesive scraping mechanism is used, under the tension of the elastic element, the first and second extrusion rollers maintain close contact with the roll material, which helps to squeeze out the excess adhesive inside the roll material. The excess adhesive is then scraped off by the scraper, achieving complete removal of excess adhesive between the tapes in a single scraping process. This greatly reduces the frequency of scraper use, reduces damage to the tape from the scraper, avoids incomplete adhesive removal, and improves adhesive removal efficiency.

[0036] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
