Abstract
Description
Technical Field
[0001] This utility model relates to the field of thickness control equipment technology, and in particular to a coating thickness control device for a coating machine. Background Technology
[0002] Coating machines are mainly used for surface coating processes of films, paper, etc. This machine coats a roll of substrate with a layer of adhesive, paint or ink with a specific function, and then dries and rewinds it. It uses a special multi-functional coating head to achieve various forms of surface coating. During the coating process, the coating thickness requirements for different materials or plastic films are different. Therefore, coating thickness control equipment is often needed to adjust and control the coating thickness.
[0003] Existing adhesive coating thickness control equipment uses a scraper fixed to a frame with screws. The frame position is then adjusted by a screw inside the guide rail, causing the frame to move the scraper left and right and adjust the distance between the scraper and the glue roller. When the glue roller rotates, it carries the glue in the glue tank. The scraper then removes excess glue from the surface of the glue roller, allowing the glue to reach the specified thickness and be applied to the fabric, thus controlling the adhesive coating thickness.
[0004] However, when the squeegee removes the glue, some glue may adhere to the squeegee surface and solidify. This solidified glue will then scrape off the glue on the glue roller surface, resulting in uneven glue coverage on the glue roller surface and affecting the glue coating quality. Utility Model Content
[0005] The technical problem this invention aims to solve is that when the scraper removes glue, some glue may adhere to the scraper surface and solidify, causing the solidified glue to scrape off the glue on the glue roller surface, resulting in uneven glue coverage on the glue roller surface and affecting the glue coating quality.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a coating thickness control device for a coating machine, comprising: a guide rail, the guide rail being disposed on a glue storage tank, wherein a glue dispensing roller is provided inside the glue storage tank; a scraper, the scraper being movably mounted on the guide rail via a frame, wherein the guide rail drives the frame to move by an internal screw, wherein the scraper and the frame are fixed by screws; and a scraping assembly, the scraping assembly being mounted on the scraper, wherein the scraping assembly moves in contact with the surface of the scraper to scrape off the glue adhering to its surface.
[0007] Preferably, the scraping assembly includes: a threaded rod, which is rotatably mounted on the scraper via a bearing bracket, wherein the threaded rod is driven by a motor; a threaded rod, the inner wall of which is threadedly connected to the surface of the threaded rod, wherein the threaded rod is placed inside a slide rail and slides left and right; and a scraper blade, wherein the scraper blade is fixed to the threaded rod and adheres to the surface of the scraper to scrape off the adhering glue.
[0008] The effect achieved by the above-mentioned components is as follows: By setting up the scraper assembly, the motor is first started to drive the threaded rod to rotate, which causes the threaded rod to move left and right along the inside of the slide rail. This causes the threaded rod to move the scraper blade left and right, so that the scraper blade moves left and right against the scraper surface and scrapes off the glue, thereby cleaning the scraper surface. At the same time, during the use of the scraper, the scraper blade is moved to the edge of the scraper to avoid the scraper blade affecting the scraping of glue off the surface of the glue roller. This reduces the situation where some glue adheres to the scraper surface and solidifies, causing the solidified glue to scrape off the glue surface of the glue roller, resulting in uneven glue coverage on the glue roller surface and affecting the glue coating quality. This improves the convenience of cleaning the scraper surface.
[0009] Preferably, the surface of the scraper is an isosceles triangle, wherein the pointed end of the scraper is on the side away from the screw hole rod.
[0010] The effect achieved by the above components is that by setting the surface of the scraper blade to an isosceles triangle, the scraper blade surface has a slope, which can guide the adhering glue and let it drip naturally, reducing the amount of glue adhering to the scraper blade surface.
[0011] Preferably, the scraper assembly further includes: a scraper bar, which is fixed to the scraper blade, wherein the surface of the scraper bar is triangular and fits against the surface of the scraper blade.
[0012] The effect achieved by the above-mentioned components is that by setting up the scraper, the scraper can scrape off the glue that is sticky or solidified on the scraper, thereby further improving the cleaning effect on the scraper surface.
[0013] Preferably, the scraper assembly further includes a rubber ring, wherein the rubber ring is symmetrically fixed to the screw hole rod, separating the screw hole rod from the bearing bracket on which the threaded rod is mounted.
[0014] The effect achieved by the above components is that by setting a rubber ring, the rubber ring can separate the threaded rod from the bearing bracket surface on which the threaded rod is installed, thereby reducing the collision and wear between the threaded rod and the bearing bracket.
[0015] Preferably, it further includes: a collection component, the collection component comprising: a rectangular frame fixed to the side of the scraper away from the scraper; and a collection box inserted inside the rectangular frame to store the glue scraped off by the scraper.
[0016] The effect achieved by the above components is as follows: By setting up the collection component, the collection box is first manually inserted into the rectangular frame, so that the collection box is fixed to the inner wall of the rectangular frame through friction. When the scraper scrapes off the glue adhering to the scraper surface, the glue falls along the scraper surface into the collection box inside the rectangular frame for storage. This achieves rapid collection of scraped glue, which is convenient for centralized processing in the future. It also reduces the situation where scraped glue falls into the glue storage tank, causing different degrees of curing of the glue inside the glue storage tank, resulting in uneven glue application and affecting the quality of glue application.
[0017] Preferably, the collection assembly further includes a handle, wherein the handle is fixed to the collection box, and the inner side of the handle has a plurality of protrusions.
[0018] The effect achieved by the above-mentioned components is that by setting handles, a point of leverage can be provided for personnel to manually move the collection box, thereby improving the convenience of manually moving the collection box.
[0019] Preferably, the collection assembly further includes a rubber strip, wherein the rubber strip is uniformly fixed to the side of the collection box.
[0020] The effect achieved by the above components is as follows: by setting the rubber strip, the rubber strip can be inserted into the rectangular frame along with the collection box, and by squeezing the inner wall of the rectangular frame, the friction between the collection box and the inner wall of the rectangular frame is increased, thereby improving the stability of the collection box when inserted into the rectangular frame.
[0021] The beneficial effects of this utility model are:
[0022] By setting up a scraper assembly, the glue adhering to the scraper surface can be scraped off, reducing the amount of glue adhering to the scraper surface and solidifying. This would prevent the solidified glue from scraping off the glue roller surface, resulting in uneven glue coverage on the glue roller surface and affecting the glue coating quality. This also improves the convenience of cleaning the scraper surface. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] Figure 1-5 The coating thickness control device of the coating machine shown includes: a guide rail 1, which is disposed on a glue storage tank 4, wherein a glue supply roller 5 is provided inside the glue storage tank 4; a scraper 3, which is movably mounted on the guide rail 1 via a frame 2, wherein the guide rail 1 drives the frame 2 to move by an internal screw, and the scraper 3 is fixed to the frame 2 by screws; and a scraping assembly 6, which is mounted on the scraper 3, wherein the scraping assembly 6 moves against the surface of the scraper 3 to scrape off the glue adhering to its surface.
[0033] Figure 3 and Figure 4The scraping assembly 6 shown includes: a threaded rod 61, which is rotatably mounted on the scraper 3 via a bearing bracket, and is driven by a motor; a threaded rod 63, the inner wall of which is threadedly connected to the surface of the threaded rod 61, and which slides left and right inside the slide rail 62; and a scraper 64, which is fixed to the threaded rod 63 and scrapes off the adhering glue by adhering to the surface of the scraper 3. By setting up the scraping assembly 6, the motor is first started to drive the threaded rod 61 to rotate, which causes the threaded rod 61 to drive the threaded rod 63 to move left and right along the inside of the slide rail 62. The screw rod 63 drives the scraper 64 to move left and right, causing the scraper 64 to move left and right against the surface of the scraper 3 and scrape off the glue, thereby cleaning the surface of the scraper 3. At the same time, during the use of the scraper 3, the scraper 64 is moved to the edge of the scraper 3 to avoid the scraper 64 affecting the scraping of glue off the surface of the glue roller 5. This reduces the situation where some glue adheres to the surface of the scraper 3 and solidifies, causing the solidified glue to be scraped off the surface of the glue roller 5, resulting in uneven glue coverage on the surface of the glue roller 5 and affecting the glue coating quality. This improves the convenience of cleaning the surface of the scraper 3.
[0034] Figure 3 and Figure 4 The surface of the scraper 64 shown is an isosceles triangle, with the pointed end of the scraper 64 on the side away from the screw hole rod 63. By making the surface of the scraper 64 an isosceles triangle, the surface of the scraper 64 has a slope, which can guide the adhering glue and make it drip naturally, reducing the amount of glue adhering to the surface of the scraper 64. The scraper assembly 6 also includes a scraper 65, which is fixed to the scraper 64. The surface of the scraper 65 is triangular and fits against the surface of the scraper 3. By setting the scraper 65, the scraper 65 can scrape off the glue with strong adhesion or solidified glue on the scraper 3, further improving the cleaning effect on the surface of the scraper 3.
[0035] Figure 3 and Figure 4 The scraper assembly 6 shown also includes a rubber ring 66, which is symmetrically fixed to the screw hole rod 63, separating the screw hole rod 63 from the bearing bracket on which the threaded rod 61 is mounted. By setting the rubber ring 66, the rubber ring 66 can separate the screw hole rod 63 from the bearing bracket surface on which the threaded rod 61 is mounted, reducing the collision and wear between the screw hole rod 63 and the bearing bracket.
[0036] Figure 4 and Figure 5The document also includes a collection component 7, which comprises a rectangular frame 71 fixed to the side of the scraper 64 away from the scraper plate 3; and a collection box 72 inserted inside the rectangular frame 71 to store the glue scraped off by the scraper 64. By setting up the collection component 7, the collection box 72 is first manually inserted into the rectangular frame 71, so that the collection box 72 is fixed to the inner wall of the rectangular frame 71 by friction. When the scraper 64 scrapes off the glue adhering to the surface of the scraper plate 3, the glue falls along the surface of the scraper 64 into the collection box 72 inside the rectangular frame 71 for storage. This achieves rapid collection of the scraped glue, facilitating centralized processing in the future. It also reduces the amount of scraped glue falling into the glue storage tank 4, which could lead to uneven curing of the glue inside the glue storage tank 4, resulting in uneven glue application and affecting the quality of glue application.
[0037] Figure 4 and Figure 5 The collection component 7 shown also includes a handle 73, which is fixedly attached to the collection box 72. The handle 73 has multiple protrusions on its inner side. By setting the handle 73, a force point can be provided for personnel to manually move the collection box 72, improving the convenience of manually moving the collection box 72. The collection component 7 also includes a rubber strip 74, which is uniformly fixedly attached to the side of the collection box 72. By setting the rubber strip 74, the rubber strip 74 can be inserted into the rectangular frame 71 along with the collection box 72. By squeezing the inner wall of the rectangular frame 71, the friction between the collection box 72 and the inner wall of the rectangular frame 71 is increased, improving the stability of the collection box 72 inserted into the rectangular frame 71.
[0038] Working principle: First, the scraper 3 is fixed to the frame 2 with screws. Then, the position of the frame 2 is adjusted by the screw inside the guide rail 1, so that the frame 2 drives the scraper 3 to move left and right and adjust the distance between the scraper 3 and the glue roller 5. When the glue roller 5 is driven to rotate by the motor, it carries the glue in the glue storage tank 4. Then, the scraper 3 scrapes off the excess glue on the surface of the glue roller 5, so that the glue reaches the specified thickness and is applied to the fabric, thereby completing the control of the glue coating thickness.
[0039] First, start the motor to drive the threaded rod 61 to rotate, which in turn drives the threaded rod 63 to move left and right along the inside of the slide rail 62. This causes the threaded rod 63 to drive the scraper 64 to move left and right, so that the scraper 64 moves left and right against the surface of the scraper 3 and scrapes off the glue, thereby cleaning the surface of the scraper 3. At the same time, during the use of the scraper 3, the scraper 64 is moved to the edge of the scraper 3 to avoid the scraper 64 affecting the scraping of glue off the surface of the glue roller 5.
[0040] First, manually insert the collection box 72 into the rectangular frame 71. The collection box 72 is fixed by the friction generated by the multiple rubber strips 74 pressing against the inner wall of the rectangular frame 71. When the scraper 64 scrapes off the glue adhering to the surface of the scraper 3, the glue falls along the surface of the scraper 64 into the collection box 72 inside the rectangular frame 71 for storage, thereby achieving rapid collection of the scraped glue.
[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
