Description

Technical Field

[0001] This utility model relates to the field of resin coating equipment technology, specifically a forward and reverse integrated adhesive coating mechanism. Background Technology

[0002] In the roller coating method of resin, it is usually necessary to selectively switch between forward coating and reverse coating according to the actual process requirements. Forward coating means that the rotation speed of the coating roller is the same as the rotation direction of the substrate, while reverse coating means that the rotation direction of the coating roller is not the same as the rotation direction of the substrate.

[0003] In the existing technology, the traditional equipment for convex coating and reverse coating are two separate sets of equipment. In the actual roller coating method, whether the resin coating method is convex or reverse coating needs to be determined comprehensively based on the specific coating equipment, the form or density of the resin, the type of substrate, and the desired coating effect in order to achieve the best coating effect. Therefore, it is necessary to continue to develop an integrated device that can simultaneously meet the needs of convex and reverse coating of resin to meet the actual use requirements. Summary of the Invention

For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0026] Please see Figure 1-3This utility model provides a technical solution: The forward and reverse integrated glue coating mechanism provided by this utility model includes a support frame 5 and a four-roller assembly mechanism. The four-roller assembly mechanism includes three horizontally arranged rollers and a large glue roller 4 arranged opposite to them. The three horizontally arranged rollers include a middle fixed roller 3 and a first moving roller 1 and a second moving roller 2 arranged on its left and right sides. The middle fixed roller 3 is arranged opposite to the large glue roller 4 below. The first moving roller 1, the second moving roller 2 and the middle fixed roller 3 are all steel rollers and are equipped with heating sleeves. The surface of the large glue roller 4 is covered with silicone and is not equipped with a heating sleeve.

[0027] The first moving roller 1 is connected to the first moving roller gap adjustment mechanism, which controls the left and right lateral movement distance of the first moving roller 1; the second moving roller 2 is connected to the second moving roller 2 gap adjustment mechanism, which controls the left and right lateral movement distance of the second moving roller 2; the gap between the first moving roller 1 and the intermediate fixed roller 3, and the glue baffles 6 set on the front and rear sides of the support frame 5 form the first glue groove 7; the gap between the second moving roller 2 and the intermediate fixed roller 3, and the glue baffles 6 set on the front and rear sides of the support frame 5 form the second glue groove 8. The glue groove spacing can be selectively controlled according to the actual melt material and coating thickness requirements, and the spacing between the first moving roller 1, the second moving roller 2 and the intermediate fixed roller 3 can be adjusted. It is highly operable, meets various usage requirements, and has a wide range of applications.

[0028] A melting device matching the first glue tank 7 and the second glue tank 8 is provided on the support frame 5 located above the three rollers. The intermediate fixed roller 3, the first moving roller 1, and the second moving roller 2 are of equal length and outer diameter and are arranged horizontally and parallel to each other on the support frame 5. The two ends of the intermediate fixed roller 3 are rotatably limited and connected to the support frame 5 through fixed support seats 9. The support frame 5 is provided with slide rails that match the sliding support seats 10 at both ends of the first moving roller 1 and the second moving roller 2. The two ends of the first moving roller 1 and the second moving roller 2 respectively drive the sliding support seats 10 to move laterally left and right along the slide rails on the support frame 5 through the moving roller gap adjustment mechanism. The moving roller gap adjustment mechanism consists of a servo motor 17, a reducer, and a ball screw 11. One end of the ball screw 11 is laterally connected to the sliding support seat 10, and the other end is connected to the shaft of the servo motor 17 through the reducer. The ball screws 11 located at both ends of the same moving roller are controlled to move synchronously by the controller and the servo motor 17, driving the moving roller to move horizontally left and right.

[0029] The large rubber roller 4 is rotatably connected to the lower part of the support frame 5 at both ends via supports 12. The large rubber roller 4 is connected to a large rubber roller gap adjustment mechanism at both ends. The vertical cylinder telescopic rod of the large rubber roller gap adjustment mechanism is connected to the support 12. The controller controls the vertical cylinder telescopic rod at both ends to extend and retract vertically in sync, driving the large rubber roller 4 to move smoothly up or down. This achieves precise control of the distance between the large rubber roller 4 and the intermediate fixed roller 3, and controls the large rubber roller 4 to press onto the intermediate fixed roller 3. Depending on whether the adhesive is applied in the forward or reverse direction, the substrate is controlled to pass through the large rubber roller 4 and press onto the intermediate fixed roller 3 directly above it. This enables selective operation of the specific forward or reverse coating mode. The integrated structure design is ingenious, with a high degree of automation, and saves time and effort in operation.

[0030] The glue melting device includes a glue melting grate 13 and a glue melting hot plate 14, which are arranged vertically opposite each other on a glue melting support frame 15. The two ends of the glue melting hot plate 14 are hinged to the glue melting support frame 15 via pivots, and the tilt angle and locking limit are adjustable via baffles on the front and rear sides of the glue melting hot plate 14 and bolts passing through the glue melting support frame 15. A slide rail and a slider are also provided on the support frame 5. The glue melting device includes a glue melting support frame 15, and a slider matching the slide rail is installed at the bottom of the glue melting support frame 15. The glue melting device can move laterally left and right along the slide rail via the glue melting support frame 15 and the slider.

[0031] The glue grate 13 and the glue hot plate 14 are mounted on the same base with a slide rail and can move laterally left and right along the slide rail. Their positions above the three steel rollers can be adjusted according to the actual situation. The relative position of the glue melting device and the glue tank can be selectively moved to the position above the first glue tank 7 or the second glue tank 8 according to the specific forward and reverse coating mode of the glue application to meet the actual use requirements.

[0032] In practical use: Place the solid resin block on the melting grate 13. The melting grate 13 is used to heat the solid resin block. After the resin block is heated and melted, it drips onto the melting hot plate 14 below for further heating. The tilt angle of the melting hot plate 14 can be adjusted arbitrarily. This can adjust the time the resin stays on it, or the resin can be selected to flow into the first glue tank 7 or the second glue tank 8 by reversing its angle. It is convenient to use and highly flexible.

[0033] Each of the four rollers is equipped with an independent power system. Each power system individually controls the required speed and direction of each roller, making it convenient to switch the direction of each roller according to the required direction when applying the colloid in the forward or reverse direction. The switching is convenient and the operation is easy.

[0034] The specific operations for different glue application modes are as follows:

[0035] Forward painting mode: such as Figure 2As shown, the melting device moves above the first glue tank 7, and the melting hot plate 14 is adjusted to an angle that meets the actual requirements of the glue material and process. Each of the four rollers is equipped with an independent power system, which controls the first moving roller 1 to rotate clockwise, the middle fixed roller 3 to rotate counterclockwise, and the large glue roller 4 to rotate clockwise. The second moving roller 2 does not participate in the work at this time and has no contact with the middle fixed roller 3.

[0036] The intermediate fixed roller 3 rotates at a higher speed than the first moving roller 1. The gap between the first moving roller 1 and the intermediate fixed roller 3 is adjusted by the gap adjustment mechanism of the first moving roller, controlling the amount of glue on the intermediate fixed roller 3. Release paper 16 on the large glue roller 4 is pressed onto the intermediate fixed roller 3 by the vertical cylinder extension rod of the large glue roller gap adjustment mechanism. Under the drive of the large glue roller 4, the glue on the intermediate fixed roller 3 is transferred to the release paper 16, completing the glue coating process. The direction of movement of the release paper 16 is the same as the direction of movement of the steel roller surface.

[0037] Reverse painting mode: such as Figure 3 As shown, the melting device moves above the second glue tank 8, and the melting hot plate 14 is adjusted to an angle into the second glue tank 8 according to the actual glue material and process requirements. Each of the four rollers is equipped with an independent power system, which controls the second moving roller 2 to rotate counterclockwise, the intermediate fixed roller 3 to rotate clockwise, and the large glue roller 4 to rotate clockwise. The first moving roller 1 does not participate in the operation and has no contact with the intermediate fixed roller 3.

[0038] The intermediate fixed roller 3 rotates at a higher speed than the second moving roller 2. The gap between the second moving roller 2 and the intermediate fixed roller 3 is adjusted by the gap adjustment mechanism of the second moving roller, controlling the amount of glue on the intermediate fixed roller 3. Release paper 16 on the large glue roller 4 is driven by the vertical cylinder extension rod of the large glue roller gap adjustment mechanism to press against the intermediate fixed roller 3. Driven by the large glue roller 4, the release paper 16 transfers the glue on the intermediate fixed roller 3 onto the paper, completing the glue coating process. The direction of movement of the release paper 16 is opposite to the direction of movement of the steel roller surface.

[0039] In summary, the forward and reverse integrated glue coating mechanism of this utility model has an ingenious structural design. By selectively combining and rotating the first moving roller 1, the second moving roller 2, the middle fixed roller 3, and the large glue roller 4 in the four-roller combination mechanism, the forward and reverse glue coating modes can be selectively switched on one machine. The operation is time-saving and labor-saving, significantly improving work efficiency and meeting the actual glue coating needs.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
