Description

Technical Field

[0001] The utility model relates to the technical field of water transfer paper base paper coating, in particular to a high-speed rubber roller anti-spin device and a coating machine. Background Art

[0002] A coater is a device used to coat a layer of glue, paint or ink with specific functions on the surface of a substrate. It is mainly used for surface coating of films, paper or cloth, etc., which can change the performance, appearance or function of the substrate. Among them, the production process of water transfer paper requires the use of a coater, because the base paper needs to be continuously transported and coated with various layers of glue, such as a film-forming adhesive layer and a hydrosol layer, through the coater's rubber roller conveyor line.

[0003] In the process of applying glue by traditional coating machines, general manufacturers usually set the glue roller to a high speed in order to apply the newly prepared glue to the base paper in time to avoid long-term accumulation of the glue or the influence of temperature, which may lead to problems such as a decrease in the viscosity or smoothness of the glue applied to the base paper.

[0004] However, when the rubber roller rotates at a high speed (for example, 8000 rpm and above, where 8000 rpm means the rubber roller rotates 8000 times per minute), the two ends of the rubber roller with glue will throw the glue onto the adjacent rubber roller surface under the action of rotational inertia, indirectly causing an increase in the amount of glue on the adjacent rubber roller surface, which directly leads to uneven glue application to the base paper, resulting in uneven glue thickness on the base paper, which seriously affects the gluing quality of the base paper.

[0035] The present disclosure provides a high-speed rubber roller anti-swing device, comprising two rubber blocking components, each of which comprises a connecting bracket and a rubber blocking plate. One end of the connecting bracket of the two rubber blocking components is respectively located on both sides of the rubber roller transmission line of the coating machine and connected to the body of the coating machine, and the other end of the connecting bracket is formed with a connecting portion; the rubber blocking plate is provided with a positioning sleeve, and the positioning sleeve is movably sleeved on the connecting portion, and the end of the rubber blocking plate away from the connecting portion is formed with a rubber blocking drainage surface, and the rubber blocking drainage surface is used to be arranged toward the end circumferential contour of the rubber roller to shield the rubber liquid thrown out of the end of the rubber roller.

[0036] See also Figures 1 to 5In order to better understand the high-speed rubber roller anti-spinning device 10 of the present application, the high-speed rubber roller anti-spinning device 10 is further explained below:

[0037] An anti-spinning device 10 for a high-speed rubber roller in one embodiment includes two rubber blocking components 10a, each of which includes a connecting bracket 100 and a rubber blocking plate 200. One end of the connecting bracket 100 of the two rubber blocking components 10a is respectively located on both sides of the transmission line of the rubber roller 600 of the coating machine and is connected to the body 500 of the coating machine, and the other end of the connecting bracket 100 is formed with a connecting portion 110; the rubber blocking plate 200 is provided with a positioning sleeve 220, and the positioning sleeve 220 is movably sleeved on the connecting portion 110, and the end of the rubber blocking plate 200 away from the connecting portion 110 is formed with a rubber blocking drainage surface 210, and the rubber blocking drainage surface 210 is used to be arranged toward the end circumferential contour of the rubber roller 600 to shield the rubber liquid thrown out from the end of the rubber roller 600.

[0038] In this embodiment, a glue blocking assembly 10a is provided on each side of the transmission line of the rubber roller 600 of the coating machine, and one end of the connection bracket 100 of the glue blocking assembly 10a is connected to the body 500 of the coating machine, and the positioning sleeve 220 of the glue blocking plate 200 is movably sleeved on the connection portion 110 of the other end of the connection bracket 100, so that the glue blocking drainage surface 210 is arranged toward the end circumferential contour of the rubber roller 600. The glue blocking drainage surface 210 of the glue blocking plate 200 of the utility model effectively blocks the glue liquid thrown out from the end of the rubber roller 600, so that the glue liquid cannot be randomly splashed onto the surface of the corresponding rubber roller 600 nearby, thereby effectively ensuring that the amount of glue liquid attached to the surface of the rubber roller 600 is uniform, avoiding the problem of different glue thickness of the bottom paper 700, and thus effectively improving the glue coating quality of the bottom paper 700.

[0039] like Figures 1 to 4 As shown, in one embodiment, the anti-spin rubber device 10 for high-speed rubber rollers further includes a fixed base 300, and the fixed base 300 is connected to the machine body; the fixed base 300 is also connected to the connecting bracket 100. In one embodiment, the fixed base 300 and the connecting bracket 100 are detachably connected. In one embodiment, the fixed base 300 is provided with a connecting hanging hole 301 and a positioning notch 302; a positioning block 120 is convexly provided at one end of the connecting bracket 100, and one end of the connecting bracket 100 is movably inserted into the hanging hole 301, and the positioning block 120 is matched with the positioning notch 302.

[0040] It can be understood that in this embodiment, the fixed base 300 and the body 500 of the coater are detachably connected, specifically by screw connection; the positioning sleeve 220 is movably sleeved on the connecting portion 110, which facilitates the installation and disassembly and cleaning of the rubber baffle 200. Among them, in this embodiment, the connecting bracket 100 is cylindrical, and the positioning block 120 on the connecting bracket 100 matches the positioning notch 302, so as to effectively prevent one end of the connecting bracket 100 from rotating along the central axis of the hanging hole 301, ensuring that the rubber baffle 200 at the other end of the connecting bracket 100 accurately blocks the glue liquid thrown out by the end of the rubber roller 600.

[0041] In other embodiments, one end of the connecting bracket 100 can also be directly welded to the body 500 of the coater, so that the connection between the connecting bracket 100 and the body 500 of the coater is more stable.

[0042] Such as Figures 1 to 4 As shown, in one of the embodiments, a plurality of distance - determining holes 1101 are formed in the outer peripheral wall of the connecting portion 110, and the plurality of distance - determining holes 1101 are linearly distributed. The positioning sleeve 220 is provided with a long slot 2201 along the distribution path of the plurality of distance - determining holes 1101. The positioning sleeve 220 is movably sleeved on the connecting portion 110, so that the long slot 2201 communicates with the plurality of distance - determining holes 1101. The rubber baffle 200 includes a limiting member 230. One end of the limiting member 230 sequentially passes through the long slot 2201 and the corresponding distance - determining hole 1101, and the other end of the limiting member 230 is clamped to the connecting portion 110.

[0043] It can be understood that by passing one end of the limiting member 230 through the long slot 2201 and the corresponding distance - determining hole 1101 in sequence, the adjustable distance of the positioning sleeve 220 sleeved on the connecting portion 110 in the extending direction (such as Figure 1 the X - double - arrow indication in the figure) is realized, so as to realize the telescopic adjustment of the rubber baffle 200, enabling the rubber baffle and drainage surface 210 to more accurately block the glue liquid thrown out by the end of the rubber roller 600. In this way, it effectively prevents the glue liquid from splashing onto the surface of the nearby corresponding rubber roller 600, and further effectively ensures that the amount of glue liquid adhered to the surface of the rubber roller 600 is uniform, avoiding the problem of uneven glue thickness on the base paper 700.

[0044] Such as Figures 1 to 4 As shown, in one of the embodiments, the limiting member 230 is in a T - shape. In one of the embodiments, a plurality of positioning notches 2202 are sequentially formed in the outer peripheral wall of the positioning sleeve 220, and each positioning notch 2202 is aligned with the corresponding distance - determining hole 1101, and the other end of the limiting member 230 is arranged in the corresponding positioning notch 2202.

[0045] It can be understood that the user can sequentially pass one end of the limit member 230 through the long slot 2201 and the corresponding fixed-distance hole 1101, so that the other end of the limit member 230 is stuck in the corresponding positioning notch 2202, effectively avoiding the problem of connection shaking when the positioning sleeve 220 of the rubber baffle 200 is sleeved on the connecting portion 110, thereby improving the structural connection stability between the positioning sleeve 220 and the connecting portion 110. At the same time, the user can remove the limit member 230 to realize the separate disassembly of the rubber baffle 200, which is convenient for the user to clean the rubber baffle drainage surface 210.

[0046] As Figure 2 , Figure 4 and Figure 5 shown, in one embodiment, a threaded connection hole 101 is formed in the end face of the other end of the connecting bracket 100; the anti-throwing rubber device 10 for high-speed rotating rubber rollers further includes an anti-disengagement threaded limit member 400, and the threaded end of the anti-disengagement threaded limit member 400 is threadedly connected to the threaded connection hole 101.

[0047] It can be understood that in order to further enhance the structural connection stability between the positioning sleeve 220 and the connecting portion 110, in this embodiment, the threaded end of the anti-disengagement threaded limit member 400 is threadedly connected to the threaded connection hole 101 on the end face of the other end of the connecting bracket 100, so that the anti-disengagement threaded limit member 400 forms a movable limit on the positioning sleeve 220, effectively reducing the risk that the positioning sleeve 220 accidentally falls off from the connecting portion 110 and scratches the rubber roller 600.

[0048] Please refer to Figures 1 to 5 together. The present application also provides a coating machine, which includes at least two anti-throwing rubber devices 10 for high-speed rotating rubber rollers as described in any of the above embodiments. The two anti-throwing rubber devices 10 for high-speed rotating rubber rollers are sequentially arranged along the direction of the conveying base paper 700 of the coating machine; the coating machine further includes a machine body 500 and a plurality of rubber rollers 600; a rubber liquid storage tank 501 is formed in the machine body 500, and the rubber liquid storage tank 501 is used for placing rubber liquid. The plurality of rubber rollers 600 together form a rubber roller 600 conveying line to brush the base paper 700; the plurality of rubber rollers 600 are located above the rubber liquid storage tank 501, and the rotating shafts of the plurality of rubber rollers 600 are respectively rotatably connected to the machine body 500, and the rotating shafts of the plurality of rubber rollers 600 are also respectively connected to the power output shafts of the driving motors.

[0049] In one embodiment, the coater further includes a plurality of current collectors 800. Each current collector 800 is provided with a communicating current collecting groove 801 and a liquid outlet hole 802. One end of each current collector 800 penetrates through the machine body 500, and the other end of the current collector 800 extends below the rubber baffle 200, such that the notch of the current collecting groove 801 faces downward of the rubber baffle 200, and the liquid outlet hole 802 communicates with a glue liquid reflux tank (not shown in the figure).

[0050] In this embodiment, by providing a rubber baffle assembly 10a on each side of the conveying line of the rubber roller 600 of the coater, and connecting one end of the connecting bracket 100 of the rubber baffle assembly 10a to the machine body 500 of the coater, and the connecting portion 110 at the other end of the connecting bracket 100 is used to connect with the positioning sleeve 220 of the rubber baffle 200, so that the rubber baffle and drainage surface 210 is arranged around a partial end circumferential contour of the rubber roller 600. The rubber baffle and drainage surface 210 of the rubber baffle 200 of the present utility model can be effectively arranged to block according to the direction of the glue liquid thrown out by the forward or reverse rotation of the rubber roller 600, so that the glue liquid cannot splash randomly onto the surface of the corresponding nearby rubber roller 600, thereby effectively ensuring that the amount of glue liquid adhered to the surface of the rubber roller 600 is uniform, avoiding the problem of uneven glue thickness of the base paper 700, and thus effectively improving the glue coating quality of the base paper 700.

[0051] Furthermore, by extending the other end of the current collector 800 below the rubber baffle 200, such that the notch of the current collecting groove 801 faces downward of the rubber baffle 200, the glue liquid on the rubber baffle and drainage surface 210 flows back to the current collecting groove 801 by its own weight, and finally flows back to the glue liquid reflux tank (not shown in the figure) through the liquid outlet hole 802 for collection.

[0052] Compared with the prior art, the present utility model has at least the following advantages:

[0053] By providing a rubber baffle assembly on each side of the conveying line of the rubber roller of the coater, and connecting one end of the connecting bracket of the rubber baffle assembly to the machine body of the coater, and the positioning sleeve of the rubber baffle is movably sleeved on the connecting portion at the other end of the connecting bracket, so that the rubber baffle and drainage surface faces the end circumferential contour of the rubber roller. The rubber baffle and drainage surface of the rubber baffle of the present utility model can effectively block the glue liquid thrown out from the end of the rubber roller, so that the glue liquid cannot splash randomly onto the surface of the corresponding nearby rubber roller, thereby effectively ensuring that the amount of glue liquid adhered to the surface of the rubber roller is uniform, avoiding the problem of uneven glue thickness of the base paper, and thus effectively improving the glue coating quality of the base paper.
