Description

Technical Field

[0001] This invention relates to the field of wallpaper production technology, and in particular to a PVC wallpaper embossing device. Background Technology

[0002] During the production process, PVC wallpaper needs to be embossed with rollers to form three-dimensional patterns on the surface. The embossing quality directly determines the appearance and grade of the product. In continuous embossing operations, PVC material is prone to releasing plasticizers, small molecule additives and powder impurities when heated. These substances will adhere to and accumulate in large quantities in the grooves of the embossing roller. After long-term use, this will cause problems such as clogging, blurring of patterns and uneven pattern depth, which will seriously affect the embossing effect.

[0003] Currently, traditional embossing equipment generally uses fixed pattern embossing rollers. The material stuck in the grooves cannot be discharged by itself and can only be removed by disassembling and cleaning after stopping the machine. This not only affects production efficiency but also easily damages the pattern on the roller surface. Although some equipment is equipped with scraping devices, the scraping mechanism is in constant contact with the roller surface, which will wear down the raised patterns and scratch the roller surface during normal embossing, reducing the embossing accuracy and service life. At the same time, the existing unclogging methods can only clean the material stuck on the surface of the roller surface and cannot penetrate to the bottom of the groove to force the accumulated material out, resulting in incomplete unclogging and easy repeated clogging.

[0004] Furthermore, the unclogging structure of traditional embossing devices makes it difficult to simultaneously perform unclogging and normal embossing without stopping the machine, thus failing to meet the demands of efficient, continuous, and high-precision embossing production for PVC wallpaper. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] In view of the problems existing in the above and / or existing PVC wallpaper embossing devices, the present invention is proposed.

[0007] Therefore, the problem to be solved by the present invention is that the groove of the embossing roller is prone to material sticking and clogging, and the clogging is not completely cleared, and the scraping mechanism cannot complete the clogging without stopping the machine.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a PVC wallpaper embossing device, comprising a frame, an embossing roller rotatably connected to one side of the frame, a driving device disposed inside the embossing roller, a scraping mechanism disposed on the surface of the embossing roller, a plurality of embossing groove opening and closing blocks disposed inside the embossing roller, and a plurality of grooves for sliding of the embossing groove opening and closing blocks being formed on the surface of the embossing roller, the grooves constituting the texture of the embossing roller; An adjustment mechanism is provided inside the embossing roller. The adjustment mechanism is used to adjust the position of the embossing groove opening and closing block inside the embossing roller so that the adhesive material in the groove corresponding to the embossing groove opening and closing block is pushed out. The scraping mechanism is an elastic scraping mechanism, and the adjusting mechanism is linked to the scraping mechanism for control. When the adjusting mechanism drives the embossing groove opening and closing block to move to the surface of the embossing roller, the scraping mechanism closely fits the surface of the embossing roller and scrapes off the material adhering to the roller surface in real time. When the adjusting mechanism does not drive the embossing groove opening and closing block to move, the scraping mechanism simultaneously disengages from the surface of the embossing roller to avoid scratching the roller surface and ensure that the embossing pattern of the embossing roller is complete and clear.

[0009] In a preferred embodiment of the PVC wallpaper embossing device of the present invention, the embossing roller is provided with a support mechanism for supporting the embossing groove opening and closing block. The support mechanism includes a support frame fixed to one side of the frame, a support shaft fixed inside the support frame, a support leg fixed to one side of the embossing groove opening and closing block, a roller rotatably connected to the end of the support leg, a first spring fixed inside the embossing groove opening and closing block, the other end of the first spring fixed to the inner wall of the embossing roller, and the roller rolling on the surface of the support shaft.

[0010] In a preferred embodiment of the PVC wallpaper embossing device of the present invention, the adjusting mechanism includes an adjusting shaft rotatably connected to the support shaft, an extrusion seat slidingly within the adjusting shaft, a second spring disposed within the extrusion seat, an adjusting seat slidingly within the support shaft, an extrusion groove formed within the adjusting seat, the adjusting shaft located within the extrusion groove, an adjusting surface formed on the surface of the adjusting seat, and the adjusting surface being tangent to the arc surface of the support shaft.

[0011] In a preferred embodiment of the PVC wallpaper embossing device of the present invention, a limiting block is fixed on one side of the adjusting seat, and a sliding groove corresponding to the sliding of the limiting block is provided in the support shaft.

[0012] In a preferred embodiment of the PVC wallpaper embossing device of the present invention, the scraping mechanism includes an installation arm, a rotating shaft rotatably connected inside the installation arm, a support arm fixed to the surface of the rotating shaft, a support plate fixed to the end of the support arm, a scraper hinged to the surface of the support plate, a pressure plate fixed to the top of the support plate, a third spring fixed between the pressure plate and the scraper, and a torsion spring provided between the installation arm and the rotating shaft.

[0013] In a preferred embodiment of the PVC wallpaper embossing device of the present invention, an air supply pipe is fixed at the bottom of the support plate, and a plurality of air blowing pipes are provided on the surface of the air supply pipe.

[0014] In a preferred embodiment of the PVC wallpaper embossing device of the present invention, a driving mechanism is provided on the surface of the adjusting shaft, the driving mechanism includes an adjusting disc fixed to the surface of the adjusting shaft, and an adjusting rod is fixed on the surface of the adjusting disc.

[0015] In a preferred embodiment of the PVC wallpaper embossing device of the present invention, an adjusting arm is fixed to the surface of the rotating shaft, and a support plate is fixed to the surface of the adjusting plate.

[0016] In a preferred embodiment of the PVC wallpaper embossing device of the present invention, a rod is slidably disposed within the adjusting disc, two positioning holes are provided at the end of the support shaft, and a fourth spring is sleeved on the rod.

[0017] In a preferred embodiment of the PVC wallpaper embossing device of the present invention, the driving device includes a driving disk rotatably connected to the frame, the driving disk being fixed inside the embossing roller, and a driving wheel being fixed on the surface of the driving disk.

[0018] The beneficial effects of this invention are as follows: by adjusting the mechanism to drive the embossing groove opening and closing block to extend and rise along the groove, the adhering material in the embossing pattern can be forcibly pushed out. In conjunction with the scraping mechanism, air supply pipe and air blowing pipe, the triple cleaning of scraping and blowing can be achieved, which can completely solve the problem of material sticking and blocking the groove of the embossing roller, and significantly improve the cleaning effect and continuous production stability.

[0019] This invention enables the linkage switching between the adjustment mechanism and the scraping mechanism through a drive mechanism. In the unclogging mode, the scraper automatically adheres to the embossing roller, while in the normal embossing mode, the scraper synchronously detaches from the roller surface. This ensures reliable unclogging and avoids scratching the embossing pattern, thus balancing the unclogging function with the embossing quality. Attached Figure Description

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1, referring to Figures 1-11 This is the first embodiment of the present invention. This embodiment provides a PVC wallpaper embossing device. The PVC wallpaper embossing device includes a frame 1. An embossing roller 2 is rotatably connected to one side of the frame 1. The embossing roller 2 can be arranged in pairs to emboss PVC wallpaper, or a smooth support roller can be used to support the PVC wallpaper. A driving device 3 is provided inside the embossing roller 2. The driving device 3 is used to drive the embossing roller 2 to rotate. A scraping mechanism 4 is provided on the surface of the embossing roller 2. The scraping mechanism 4 is used to scrape off the adhesive on the surface of the embossing roller 2. A plurality of embossing groove opening and closing blocks 2-1 are provided inside the embossing roller 2. The embossing groove opening and closing blocks 2-1 slide inside the embossing roller 2. A plurality of grooves 2-2 are opened on the surface of the embossing roller 2 for the sliding of the embossing groove opening and closing blocks 2-1. The plurality of grooves 2-2 constitute the texture of the embossing roller 2. An adjustment mechanism 5 is provided inside the embossing roller 2. The adjustment mechanism 5 is used to adjust the position of the embossing groove opening and closing block 2-1 inside the embossing roller 2, so that the adhesive in the groove 2-2 corresponding to the embossing groove opening and closing block 2-1 is pushed out. The scraping mechanism 4 is an elastic scraping mechanism that can closely adhere to the surface of the embossing roller 2. The adjusting mechanism 5 and the scraping mechanism 4 are linked for control. When the adjusting mechanism 5 drives the embossing groove opening and closing block 2-1 to move to the surface of the embossing roller 2, the end face of the embossing groove opening and closing block 2-1 coincides with the cylindrical surface of the embossing roller 2, and the scraping mechanism 4 closely adheres to the surface of the embossing roller 2 to scrape off the sticky material on the roller surface in real time. When the adjusting mechanism 5 does not drive the embossing groove opening and closing block 2-1 to move, the scraping mechanism 4 simultaneously disengages from the surface of the embossing roller 2 to avoid scratching the roller surface and ensure that the embossing pattern of the embossing roller 2 is complete and clear.

[0037] Example 2, refer to Figures 1-11 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the embossing roller 2 is provided with a support mechanism 6 for supporting the embossing groove opening and closing block 2-1. The support mechanism 6 includes a support frame 61 fixed to one side of the frame 1, and a support shaft 62 fixed inside the support frame 61, so that the support shaft 62 remains stationary when the embossing roller 2 rotates. A support leg 63 is fixed to one side of the embossing groove opening and closing block 2-1, and a roller 64 is rotatably connected to the end of the support leg 63. A first spring 65 is fixed inside the embossing groove opening and closing block 2-1, and the other end of the first spring 65 is fixed to the inner wall of the embossing roller 2. The first spring 65 is in a compressed state and is used to push the embossing groove opening and closing block 2-1 into the embossing roller 2, so that the roller 64 rolls on the surface of the support shaft 62. At this time, the roller 64 rolls on the cylindrical surface of the support shaft 62, so that each embossing groove opening and closing block 2-1 is at the same distance from the surface of the embossing roller 2.

[0039] The embossing groove opening and closing blocks 2-1 are fixedly connected by connecting seats 66, so that multiple embossing groove opening and closing blocks 2-1 can move up and down synchronously.

[0040] The adjusting mechanism 5 includes an adjusting shaft 51 rotatably connected to the support shaft 62. A pressing seat 52 slides within the adjusting shaft 51. A second spring 54 is installed within the pressing seat 52 and is in a compressed state to push the pressing seat 52. Multiple adjusting seats 55 slide within the support shaft 62. Each adjusting seat 55 has a pressing groove 55-1. The adjusting shaft 51 is located within the pressing groove 55-1. The pressing seat 52 pushes the pressing groove 55-1, thereby driving the adjusting seat 55 to move. The surface of the adjusting seat 55 is... An adjustment surface 55-2 is provided, which is tangent to the arc surface of the support shaft 62. When the adjustment seat 55 moves out of the support shaft 62, so that the adjustment surface 55-2 and the arc surface of the support shaft 62 are tangent, the roller 64 can move from the arc surface of the support shaft 62 to the adjustment surface 55-2, thereby causing the support leg 63 to push the embossing groove opening and closing block 2-1, so that the end face of the embossing groove opening and closing block 2-1 coincides with the cylindrical surface of the embossing roller 2. At this time, the scraping mechanism 4 closely fits the surface of the embossing roller 2 and scrapes off the sticky material on the roller surface in real time.

[0041] A limiting block 55-3 is fixed on one side of the adjusting seat 55, and a sliding groove 62-1 corresponding to the sliding of the limiting block 55-3 is opened in the support shaft 62, so that the adjusting seat 55 stops moving when it moves to the position where the adjusting surface 55-2 and the arc surface of the support shaft 62 are tangent.

[0042] The scraping mechanism 4 includes a mounting arm 41, a rotating shaft 42 rotatably connected inside the mounting arm 41, a support arm 43 fixed to the surface of the rotating shaft 42, a support plate 44 fixed to the end of the support arm 43, a scraper 45 hinged to the surface of the support plate 44, a pressure plate 46 fixed to the top of the support plate 44, and a third spring 47 fixed between the pressure plate 46 and the scraper 45. The third spring 47 is in a compressed state. A torsion spring is provided between the mounting arm 41 and the rotating shaft 42, so that the rotating shaft 42 drives the support arm 43 to press towards the embossing roller 2. This causes the support plate 44 at the end of the support arm 43 to press the scraper 45 through the pressure plate 46 and the third spring 47, so that the scraper 45 is tightly attached to the surface of the embossing roller 2, thereby scraping off the adhesive material pushed out by the embossing groove opening and closing block 2-1.

[0043] The bottom of the support plate 44 is fixed with an air supply pipe 48. The surface of the air supply pipe 48 is provided with multiple air blowing pipes 49. The multiple air blowing pipes 49, together with the arc-shaped structure of the scraper 45, can make the airflow at the inner wall of the scraper 45 move in the axial direction of the embossing roller 2, thereby blowing off the adhesive material scraped off by the scraper 45 and preventing the adhesive material from accumulating.

[0044] The middle part of the adjusting surface 55-2 is an arc-shaped surface with the same center as the embossing roller 2. When the roller 64 moves in this area, the end face of the embossing groove opening and closing block 2-1 and the cylindrical surface of the embossing roller 2 remain in the same state. In this way, when the end face of the embossing groove opening and closing block 2-1 passes the scraper 45, the sticky material pushed out by the embossing groove opening and closing block 2-1 can be scraped off.

[0045] When the roller 64 moves to the surface of the support shaft 62, the embossing groove opening and closing block 2-1 returns to its initial position, without affecting the embossing of the PVC wallpaper, so that scraping and embossing can be carried out simultaneously.

[0046] Example 3, referring to Figures 1-11 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0047] Specifically, a drive mechanism 7 is provided on the surface of the adjusting shaft 51. The drive mechanism 7 includes an adjusting disc 71 fixed to the surface of the adjusting shaft 51. An adjusting rod 72 is fixed on the surface of the adjusting disc 71. By pulling the adjusting rod 72, the adjusting disc 71 can be rotated, thereby driving the adjusting shaft 51 to rotate. When the adjusting shaft 51 rotates 180 degrees from its current state, the pressing seat 52 inside the adjusting shaft 51 can press the pressing groove 55-1 of the adjusting seat 55, thereby causing the adjusting seat 55 to retract into the support shaft 62. At this time, the roller 64 no longer contacts the adjusting seat 55.

[0048] Two adjusting arms 73 are fixed on the surface of the rotating shaft 42, and a support plate 74 is fixed on the surface of the adjusting plate 71. When the adjusting plate 71 rotates 180 degrees from the state shown in the figure, the support plate 74 can support the adjusting arms 73, thereby driving the rotating shaft 42 to deflect. This causes the rotating shaft 42 to drive the support arms 43 and the support plate 44 away from the embossing roller 2. Through the support plate 44 supporting the scraper 45, the scraper 45 can be kept away from the embossing roller 2, avoiding scratching the roller surface when not in use and ensuring that the embossing pattern of the embossing roller 2 is complete and clear.

[0049] A rod 75 slides inside the adjusting disc 71. Two positioning holes 62-2 are opened at the end of the support shaft 62. A fourth spring 76 is sleeved on the rod 75. Under the push of the fourth spring 76, the rod 75 is inserted into the positioning hole 62-2. When the adjusting disc 71 rotates 180 degrees, the rod 75 is inserted into the other positioning hole 62-2, thereby fixing the angle of the adjusting shaft 51 in the two states.

[0050] The drive device 3 includes a drive disk 31 rotatably connected to the frame 1. The drive disk 31 is fixed inside the embossing roller 2. Both ends of the embossing roller 2 are provided with drive disks 31. A drive wheel 32 is fixed on the surface of the drive disk 31. The drive wheel 32 can be a pulley or a gear, etc., used to drive the drive disk 31 to rotate, thereby driving the embossing roller 2 to rotate.

[0051] When in use, the PVC wallpaper is placed between the paired embossing rollers 2. The drive wheel 32 drives the drive disc 31 to rotate, thereby causing the embossing rollers 2 to rotate synchronously and perform continuous embossing on the PVC wallpaper.

[0052] When adhesive residue accumulates on the groove 2-2 on the surface of the embossing roller 2 and needs to be cleaned, rotate the adjusting rod 72 of the drive mechanism 7 to make the adjusting plate 71 drive the adjusting shaft 51 to rotate. The extrusion seat 52 inside the adjusting shaft 51 pushes the extrusion groove 55-1 of the adjusting seat 55 under the action of the second spring 54, so that the adjusting seat 55 extends outward along the slide groove 62-1 of the support shaft 62 until the adjusting surface 55-2 is tangent to the arc surface of the support shaft 62.

[0053] During the rotation of the embossing roller 2, the roller 64 at the bottom of the embossing groove opening and closing block 2-1 rolls from the cylindrical surface of the support shaft 62 to the adjustment surface 55-2, pushing the support leg 63 and the embossing groove opening and closing block 2-1 to move towards the surface of the embossing roller 2, so that the end face of the embossing groove opening and closing block 2-1 coincides with the cylindrical surface of the embossing roller 2, pushing the adhering material in the groove 2-2 outward, and realizing the forced discharge of the material accumulated inside the groove.

[0054] At the same time, after the adjusting disc 71 rotates, it releases the support of the adjusting arm 73. Under the action of the torsion spring, the rotating shaft 42 drives the support arm 43 and the support plate 44 to move closer to the embossing roller 2. Under the pressure of the third spring 47, the scraper 45 is tightly attached to the surface of the embossing roller 2 to scrape off the sticky material in real time. With the help of the air supply pipe 48 and the air blowing pipe 49, air is blown along the axial direction of the embossing roller 2 to blow off the scraped sticky material in time and avoid accumulation. This achieves the triple cleaning effect of internal ejection, external scraping and airflow purging.

[0055] During cleaning, only the end face of the embossing groove opening and closing block 2-1 near the scraper 45 coincides with the cylindrical surface of the embossing roller 2. The embossing groove opening and closing block 2-1 in the groove 2-2 below, which is used to emboss the PVC wallpaper, remains in its original position and does not affect the embossing of the PVC wallpaper.

[0056] When cleaning is completed and normal embossing operation is resumed, rotate the adjusting rod 72 again to reset the adjusting plate 71. The adjusting shaft 51 drives the pressing seat 52 to press the adjusting seat 55 in the opposite direction, and the adjusting seat 55 retracts into the support shaft 62. The roller 64 rolls again on the cylindrical surface of the support shaft 62, and the embossing groove opening and closing block 2-1 retracts into the embossing roller 2 under the action of the first spring 65.

[0057] At the same time, the support plate 74 on the adjustment plate 71 lifts the adjustment arm 73, causing the rotating shaft 42 to deflect, so that the support arm 43, the support plate 44 and the scraper 45 move away from the surface of the embossing roller 2 in sync, so as to avoid the scraper 45 scratching the roller surface pattern and ensure that the embossing pattern is complete and clear.

[0058] The insertion rod 75 is inserted into the corresponding positioning hole 62-2 under the action of the fourth spring 76, fixing the adjusting shaft 51 at the current working angle, so that the switching between the embossing mode and the unblocking mode is stable and reliable.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
