DETAILED DESCRIPTION

[0022] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0023] The plywood double-sided rubber rolling device of the present application is described below in combination with the drawings.

[0024] As Figures 1-5 shown, the plywood double-sided rubber rolling device of the present application can include two side frames 10 and an upper die set 20 and a lower die set 30 between the two side frames 10.

[0025] The upper die set 20 is connected to the side frame 10 through a lifting part 40, and the lifting part 40 is provided with two, one between each side frame 10 and the upper die set 20, and the lifting part 40 can include a spring 41 and a sliding block 42, wherein the side frame 10 is provided with a sliding groove 11, the sliding block 42 is slidably arranged in the corresponding sliding groove 11, and the sliding block 42 is connected to the upper die frame 21, and the spring 41 is vertically arranged and its two ends are respectively connected to the sliding block 42 and the inner wall of the sliding groove 11.

[0026] It should be noted that the upper die set 20 described in this embodiment can be precisely adjusted in height according to the specific height of the plate to be rubberized 80. The built-in spring 41 is designed ingeniously to ensure that the upper roller assembly can moderately press the plate 80 on the lower roller assembly, which not only realizes the stable conveying of the plate 80, but also ensures that the plate 80 can be evenly treated by double-sided rubber rolling during conveying.

[0027] The upper die set 20 can include an upper die frame 21, an upper roller assembly and two moving pieces 24. The upper roller assembly is movably arranged on the upper die frame 21 by a first driving mechanism 50. The upper roller assembly can include two first conveying rollers 23 and an upper glue roller 22 arranged between the two first conveying rollers 23. The upper glue roller 22 and the two first conveying rollers 23 are arranged transversely side by side, and a plurality of annular grooves 221 are longitudinally distributed on the outer side of the upper glue roller 22. The two moving pieces 24 are symmetrically arranged on both sides of the upper die frame 21 by an adjusting mechanism 60. One side of the moving piece 24 is formed with a containing groove 241 for containing glue. The upper glue roller 22 is in sliding contact with the opening side wall of the containing groove 241. Two side edge rollers 242 are movably arranged on one side of the moving piece 24.

[0028] It should be noted that the moving piece 24 and the upper glue roller 22 described in this embodiment are in close sliding fit. The glue on the outer side of the upper glue roller 22 will enter the plurality of annular grooves 221. Once the width of the containing groove 241 is adjusted, with the continuous rotation of the upper glue roller 22, the annular grooves 221 located inside the containing groove 241 and adjacent to the edge of the moving piece 24 play a key role. They can effectively block and limit the glue attached to the outer edge of the upper glue roller 22, significantly reducing the unnecessary spreading of the glue to both sides during rotation, ensuring the accurate control of the glue covering width of the upper glue roller 22, and further ensuring the accuracy of the glueing of the plate 80.

[0029] It should be noted that the adjusting mechanism 60 described in this embodiment can control the moving piece 24 to move close to or away from each other, thereby realizing the accurate adjustment of the width of the containing groove 241.

[0030] The lower die set 30 can include a lower die frame 31 and a lower roller assembly. The top surface of the lower die frame 31 is formed with a glue groove 311. The lower roller assembly is movably arranged on the lower die frame 31 by a second driving mechanism 70. The lower roller assembly can include a lower glue roller 32 and two second conveying rollers 33 arranged on both sides of the lower glue roller 32 respectively. The lower glue roller 32 is located directly below the upper glue roller 22 and is located in the glue groove 311. The second conveying rollers 33 are located directly below the corresponding first conveying rollers 23. It should be noted that when the upper glue roller 22 rotates, the glue in the containing groove 241 described in this embodiment can be uniformly attached to the outer surface of the upper glue roller 22 and be accurately transferred to the top surface of the plate 80 with the rotation of the upper glue roller 22.

[0031] Similarly, during the rotation of the lower glue roller 32, the glue in the glue groove 311 described in this embodiment can also be uniformly attached to the outer surface of the lower glue roller 32 and be accurately transferred to the bottom surface of the plate 80 with the rotation of the lower glue roller 32.

[0032] It should be noted that the first drive mechanism 50 described in this embodiment can drive the upper roller assembly to rotate synchronously, and the second drive mechanism 70 described in this embodiment can drive the lower roller assembly to rotate synchronously, thereby ensuring the coordination and efficiency of the entire gluing process.

[0033] Specifically, when performing the double-sided roller gluing operation of the plate 80, the operator will first accurately place the plate 80 between the first conveying roller 23 and the second conveying roller 33. During this process, the first conveying roller 23 will drive the upper mold frame 21 to adjust upward according to the actual height of the plate 80, and at the same time, the sliding block 42 will exert a corresponding stretching force on the spring 41, and the plate 80 will be tightly clamped between the first conveying roller 23 and the second conveying roller 33 by the elastic force of the spring 41. Subsequently, the first conveying roller 23 and the second conveying roller 33 rotate synchronously, thereby smoothly conveying the plate 80.

[0034] As the plate 80 continues to move, it will enter the area composed of two side rollers 242. At this time, the operator will accurately control the two moving pieces 24 to move closer to each other by using the adjusting mechanism 60, until the two side rollers 242 are in close contact with the two sides of the plate 80, which not only ensures the stability of the plate 80 during conveying, but also accurately limits the plate 80 through the rotation of the side rollers 242.

[0035] During the movement of the moving piece 24, the width of the accommodating groove 241 will change accordingly, which can realize the accurate adjustment of the glue covering width of the gluing roller 22, thereby ensuring the accuracy of the gluing of the plate 80.

[0036] Finally, the plate 80 will enter the gluing area composed of the gluing roller 22 and the lower gluing roller 32. The gluing roller 22 is responsible for uniformly gluing the top surface of the plate 80, and the lower gluing roller 32 is responsible for the same operation for the bottom surface of the plate 80. After gluing is completed, the plate 80 will continue to be conveyed under the cooperation of another set of first conveying roller 23 and second conveying roller 33 until it completely moves out of the device.

[0037] In an embodiment of the present application, as shown in Figure 3 The adjusting mechanism 60 can include a third motor 61 and a bidirectional screw 62, wherein the bidirectional screw 62 is arranged on the upper mold frame 21 through the third motor 61, and the screw threads on the symmetrical two sides thereof are opposite in direction, and the two moving pieces 24 are respectively threadedly sleeved on the symmetrical two sides of the bidirectional screw 62. The moving piece 24 is slidably connected with the upper mold frame 21.

[0038] It should be noted that the third motor 61 described in this embodiment can drive the bidirectional screw 62 connected thereto to rotate forward or reverse after being started, and with the rotation of the bidirectional screw 62, the two moving pieces 24 will move closer or farther away according to the rotation direction of the screw.

[0039] In one embodiment of the present application, as shown in Figures 3-4 The first driving mechanism 50 can include a first motor 51, three first sprockets 52 and two first chains 53. The three first sprockets 52 are respectively arranged on the two first conveying rollers 23 and the gluing roller 22. The gluing roller 22 and the first conveying rollers 23 are connected through the first chains 53. The first chains 53 are meshed with the corresponding first sprockets 52. The first motor 51 is connected with one of the first sprockets 52.

[0040] The second driving mechanism 70 can include a second motor 71, three second sprockets 72 and two second chains 73. The three sprockets are respectively arranged on the two second conveying rollers 33 and the lower gluing roller 32. The lower gluing roller 32 and the second conveying rollers 33 are connected through the second chains 73. The second chains 73 are meshed with the corresponding second sprockets 72. The second motor 71 is connected with one of the second sprockets 72.

[0041] It should be noted that after the first motor 51 is started in this embodiment, it can drive the first sprocket 52 connected thereto to start rotating. This rotating action can be transmitted through the two first chains 53 to make the other two first sprockets 52 rotate synchronously and in the same direction, thereby driving the entire upper roller assembly into a working state.

[0042] Similarly, after the second motor 71 is started in this embodiment, it can drive the second sprocket 72 connected thereto to rotate. This rotating action can be transmitted through the two second chains 73 to make the other two second sprockets 72 rotate synchronously and in the same direction, thereby driving the entire lower roller assembly into a working state.

[0043] In summary, the plywood double-sided gluing device of the present application can adapt to gluing work on different widths and heights of the board. By moving the two moving members closer or farther apart, the distance between the two side rollers can be accurately adjusted, and the width of the accommodating groove can be correspondingly changed. This design, combined with the multiple annular grooves cleverly arranged on the outer side of the gluing roller, realizes accurate adjustment of the gluing roller's glue coverage width, thereby ensuring the accuracy of the board gluing.
