They are characterized by convenient construction and low cost, and are widely used in homes, offices and other settings.

[0003] In existing self-adhesive floor sticker production processes, a film needs to be applied to the floor sticker. During the application process, a pressure roller is used to bond the film to the floor sticker. However, due to limitations in the hardness and pressure uniformity of the pressure roller, existing application equipment cannot completely eliminate residual gas between the film layer and the floor sticker, resulting in air bubbles between the film layer and the floor sticker, which affects the quality of the floor sticker application. Utility Model Content

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] See Figures 1-4 This embodiment provides a self-adhesive flooring film pressing structure, including a frame 1, a conveying mechanism 2, a defoaming mechanism 3, and a pressing mechanism 4. The conveying mechanism 2, the defoaming mechanism 3, and the pressing mechanism 4 are all located within the frame 1. The conveying mechanism 2 is used to move the flooring film after it has been applied into the defoaming mechanism 3 and the pressing mechanism 4 in sequence. The defoaming mechanism 3 and the pressing mechanism 4 respectively perform bubble removal and pressing operations on the flooring film.

[0022] This invention uses a conveying mechanism 2 to transport floor stickers, and a defoaming mechanism 3 and a pressing mechanism 4 to successively perform defoaming and pressing operations on the floor stickers, thereby eliminating residual gas between the film layer and the floor stickers, removing air bubbles between the film layer and the floor stickers, and improving the film quality of the floor stickers.

[0023] See Figure 3 The defoaming mechanism 3 includes a first lead screw motor 31, a drive motor 32, and a scraper 33. The first lead screw motor 31 is fixed inside the frame 1. A first slider 34 is slidably arranged on the lower side of the first lead screw motor 31. The first slider 34 is driven to move up and down by the first lead screw motor 31. The drive motor 32 is fixed on the first slider 34. The scraper 33 is fixed on the rotating shaft of the drive motor 32 and is located on the upper side of the conveying mechanism 2.

[0024] When the defoaming mechanism 3 is working, the first slider 34 is driven downward by the first lead screw motor 31, which causes the drive motor 32 and scraper 33 to move downward. At this time, the floor sticker after film application is placed on the conveying mechanism 2, and the lower surface of the scraper 33 abuts against the film layer of the floor sticker. The drive motor 32 drives the scraper 33 to rotate and apply uniform pressure to the film layer, thereby facilitating the expulsion of air bubbles between the film layer and the floor sticker and improving the film application quality of the floor sticker.

[0025] See Figure 4The scraper 33 is disc-shaped, and its diameter is greater than the length of the diagonal of the floor sticker. The lower side of the scraper 33 is provided with a plurality of scraping strips 35 at equal intervals around its circumference. The straight line of the scraping strips 35 does not intersect with the rotation axis of the disc. An elastic pressing member 36 is fixed at the center of the lower side of the disc. The pressing member 36 contacts the inner end of the scraping strips 35, and the upper and lower thickness of the pressing member 36 is greater than the upper and lower thickness of the scraping strips 35.

[0026] When the scraper 33 is driven to rotate by the drive motor 32 ( Figure 4 The scraper 33 rotates counterclockwise. Since the angle between the inner end of the scraper 35 and its direction of movement is obtuse, when the scraper 35 contacts an air bubble, it provides a force pointing outwards from the scraper 33. Therefore, the scraper 35 drives the air bubble to gradually move outwards from the edge of the floor sticker until it is expelled. When the scraper 33 presses down on the film and floor sticker, the pressing element 36 first contacts the film. If an air bubble exists on the underside of the pressing element 36, it can move outwards under the pressure of the pressing element 36 until the pressing element 36 deforms and the scraper 35 adheres to the film. The rotation of the scraper 35 then expels the air bubble, achieving the effect of eliminating air bubbles. This invention removes air bubbles by driving the scraper 33 to rotate, which has the advantage of simple structure. At the same time, compared with the existing method of using scrapers or pressure rollers to reciprocate and press the film layer to eliminate air bubbles, the scraper 33 in this invention eliminates air bubbles faster, thereby improving the efficiency of air bubble elimination.

[0027] See Figure 2 The conveying mechanism 2 includes a synchronous belt 21, synchronous pulleys 22, and a servo motor 23. There are two synchronous pulleys 22, which are symmetrically arranged in the frame 1. The servo motor 23 is fixed in the frame 1 and drives the synchronous pulley 22 located on the left to rotate. The synchronous belt 21 is sleeved on the two synchronous pulleys 22. The synchronous belt 21 is located below the defoaming mechanism 3 and the pressing mechanism 4. Two limit blocks 24 are provided on the synchronous belt 21.

[0028] In this invention, the distance between the two limiting blocks 24 is adapted to the left and right width of the floor sticker. By placing the floor sticker between the two limiting blocks 24, the limiting blocks 24 limit the floor sticker, reducing the probability of the floor sticker moving during the bubble removal and pressing process. At the same time, the servo motor 23 can control the rotation angle of the synchronous wheel 22 more precisely, thereby controlling the rotation distance of the synchronous belt 21, so that the floor sticker can move precisely below the defoaming mechanism 3 and the pressing mechanism 4, ensuring the normal operation of the bubble removal and pressing process.

[0029] See Figure 3The pressing mechanism 4 includes a second lead screw motor 41 and a pressure plate 42. The second lead screw motor 41 is fixed inside the frame 1. A second slider 43 is slidably arranged on the lower side of the second lead screw motor 41. The second slider 43 is driven to move up and down by the second lead screw motor 41. The pressure plate 42 is fixed on the second slider 43 and is located on the upper side of the conveying mechanism 2.

[0030] In this invention, the area of ​​the pressure plate 42 should be larger than the area of ​​the floor sticker. When the pressing mechanism 4 is working, the second slider 43 is driven to move downward by the second lead screw motor 41, so that the pressure plate 42 moves downward and the lower surface of the pressure plate 42 abuts against the film layer of the floor sticker. The pressure plate 42 is further driven to move downward by the second lead screw motor 41 to press the film layer, thereby achieving the pressing effect of the film layer and the floor sticker.

[0031] See Figure 2 The inner side of the synchronous belt 21 is provided with a support plate 25, which is fixed inside the frame 1. The lower side of the synchronous belt 21 located above the synchronous pulley 22 is in contact with the upper side of the support plate 25.

[0032] The timing belt 21 is supported by the support plate 25, which reduces the possibility of deformation of the timing belt 21 when the scraper 33 and the pressure plate 42 press the film layer, thus reducing the adhesion effect between the scraper 33 and the pressure plate 42 and the film layer, and ensuring the quality of bubble elimination and pressing operation.

[0033] See Figure 1 , Figure 2 The frame 1 has a hollow box structure. The left and right sides of the frame 1 are respectively provided with an openable feed port 11 and a discharge port 12. The feed port 11 and the discharge port 12 are located on the left and right sides of the synchronous belt 21, respectively. A vacuum pump 13 is fixed at the upper end of the frame 1. The vacuum pump 13 is connected to the internal cavity of the frame 1.

[0034] The positions of the inlet 11 and outlet 12 facilitate the placement and removal of the floor stickers onto the synchronous belt 21. By operating the vacuum pump 13, the air pressure inside the frame 1 is lower than the external atmospheric pressure. Under the action of negative pressure, it is easy for bubbles to be discharged from the membrane layer, thereby improving the working efficiency of the defoaming mechanism 3.

[0035] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
