Description

Technical Field

[0001] The utility model relates to the technical field of sandpaper production equipment, in particular to a glue coating structure. Background Art

[0002] In the production process of sandpaper, glue coating equipment is required to coat glue on the sandpaper base before entering the subsequent process. In the prior art, the glue coating equipment generally includes a plurality of tensioning rollers, which are used to tension the base (i.e., the base cloth of the sandpaper, on which the abrasive particles are attached to form the sandpaper), and a glue coating roller, which is located below the tensioning roller, and the base passes between the glue coating roller and a tensioning roller located at a lower position. A glue tank is also provided below the glue coating roller, which is filled with glue. The glue coating roller is partially located in the glue tank, and the glue is attached to the roller surface during rotation, and then the glue moves upward with the rotation, and then transferred to the base. As the glue is consumed, the glue attached to the roller surface will change after the glue becomes less (the glue is replenished after it becomes less, and then returns to the initial state of more glue), resulting in a large difference in the amount of glue at different times, and ultimately making the base of the same batch unevenly coated. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a glue coating structure, which solves the problem in the prior art that the glue changes in the glue tank lead to uneven glue coating on the base layer of the same batch.

[0004] According to an embodiment of the utility model, a glue coating structure includes an upper pressing roller and a glue coating roller located below the upper pressing roller, a gap is arranged between the upper pressing roller and the glue coating roller for the base layer to pass through, and the base layer is in close contact with the roller surface of the upper pressing roller and in contact with the roller surface of the glue coating roller; it also includes a glue tank, and a flow stabilizing component is arranged between the glue tank and the glue tank to stabilize the glue liquid level in the glue tank.

[0005] In the above embodiment, glue is added to the glue tank through the glue tank, and at the same time, a flow stabilizing component is provided between the glue tank and the glue tank to stabilize the liquid level in the glue tank, thereby reducing the variation range of the glue in the glue tank, thereby making the amount of glue on the glue coating roller relatively less variable. Therefore, the glue on the base layer after coating is more uniform, thus solving the problem of uneven glue coating on the base layer of the same batch caused by the variation of the glue in the glue tank in the prior art.

[0006] Furthermore, the flow stabilizing component includes a liquid receiving box and a floating plate located below the liquid receiving box and moving up and down relative to the liquid receiving box. A lower liquid hole is also provided at the bottom of the liquid receiving box, and when the floating plate is against the liquid receiving box, the floating plate covers the lower liquid hole. A connecting pipe is connected between the liquid receiving box and the glue tank.

[0007] Furthermore, a sliding hole is provided at the bottom of the liquid receiving box, the lower liquid hole includes a plurality of holes surrounding the sliding hole, the floating plate is fixedly connected to a sliding column and the sliding column is in sliding contact with the sliding hole, and the sliding column is also fixedly connected to a limiting plate located in the liquid receiving box.

[0008] Furthermore, the lower liquid hole is a frustum-shaped structure, and a plurality of plugs which can be respectively inserted into each lower liquid hole are fixedly connected to the floating plate.

[0009] Furthermore, the liquid receiving box is fixedly connected with a buckle plate, and the buckle plate is buckled with the upper end of the side wall of the glue tank.

[0010] Furthermore, a rubber coating layer is fixedly disposed around the rubber coating roller, and a grid pattern is arranged on the outer wall of the rubber coating layer.

[0011] Furthermore, it also includes a first tensioning roller and a second tensioning roller located obliquely above both sides of the upper pressure roller.

[0012] Furthermore, it also includes a third tensioning roller located below the second tensioning roller.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] By setting a flow stabilization component between the glue tank and the glue trough, the liquid level in the glue trough tends to be stable, reducing the change range of the glue in the glue trough, so that the amount of glue on the glue coating roller changes less relatively, so the glue on the base layer after coating is more uniform, solving the problem of uneven glue coating on the base layer of the same batch due to changes in the glue in the glue trough in the prior art.

[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] In an exemplary embodiment, Figure 1 , 2 As shown, this embodiment provides a glue coating structure, which includes an upper pressing roller 1 and a glue coating roller 2 located below the upper pressing roller 1, a gap is arranged between the upper pressing roller 1 and the glue coating roller 2 for a base layer 3 to pass through, and the base layer is in close contact with the roller surface of the upper pressing roller 1 and in contact with the roller surface of the glue coating roller 2; it also includes a glue tank 4, and a roller surface portion of the glue coating roller 2 is located in the glue tank 4; it also includes a glue tank 5, and a flow stabilizing component is arranged between the glue tank 5 and the glue tank 4 to stabilize the glue liquid level in the glue tank 4.

[0024] In the above embodiment, glue is added to the glue tank 4 through the glue tank 5, and a flow stabilizing component is provided between the glue tank 5 and the glue tank 4 to stabilize the liquid level in the glue tank 4, thereby reducing the variation of the glue in the glue tank 4, thereby making the amount of glue on the glue coating roller 2 relatively change less, so that the glue on the base layer 3 after coating is more uniform, thereby solving the problem of uneven glue coating on the base layer 3 of the same batch caused by the change of the glue in the glue tank 4 in the prior art; specifically, the glue coating structure also includes a first tensioning roller 6 and a second tensioning roller 7 located obliquely above both sides of the upper pressure roller 1, and a third tensioning roller 8 located below the second tensioning roller 7. , the base layer 3 passes through the first tensioning roller 6, bypasses the upper pressure roller 1, the third tensioning roller 8, and the second tensioning roller 7 in sequence, passes between the upper pressure roller 1 and the glue coating roller 2, and the glue on the glue coating roller 2 is transferred to the base layer 3; more specifically, the flow stabilizing component includes a liquid receiving box 9 and a floating plate 10 located below the liquid receiving box 9 and moving up and down relative to the liquid receiving box 9. The bottom of the liquid receiving box 9 is also provided with a lower liquid hole 11, and when the floating plate 10 is against the liquid receiving box 9, the floating plate 10 covers the lower liquid hole 11. A connecting pipe 12 is connected between the liquid receiving box 9 and the glue tank 5. The glue in the glue tank 5 is introduced into the glue tank through the connecting pipe 12, and then passes through the lower liquid hole 11 After entering the glue tank 4, when the glue liquid level in the glue tank 4 contacts the floating plate 10, the glue liquid continues to increase, and the floating plate 10 rises accordingly, and then contacts the bottom of the liquid receiving box 9, thereby covering the lower liquid hole 11 to cut off the glue liquid flow, and then as the coating progresses, the glue liquid will decrease, and the floating plate 10 moves down, and the glue liquid will then be replenished to the glue tank 4 through the lower liquid hole 11, and this reciprocating process keeps the amount of glue liquid within a very small fluctuation range, thereby ensuring uniform glue coating; further, a sliding hole is provided at the bottom of the liquid receiving box 9, and the lower liquid hole 11 includes a plurality of sliding holes surrounding the sliding hole, and the floating plate 10 is fixedly connected to a sliding column 13 and the sliding column 13 is connected to the sliding column 13 The movable hole is in sliding contact, and the sliding column 13 is also fixedly connected to a limit plate 14 located in the liquid receiving box 9. The limit plate 14 is larger than the sliding hole, so that the sliding column 13 will not be separated from the sliding hole, and at the same time does not cover the lower liquid hole 11, thereby ensuring the normal flow of the glue liquid; in more detail, the lower liquid hole 11 is a frustum-shaped structure, and the floating plate 10 is fixedly connected to a plurality of plugs 15 that can be respectively inserted into each lower liquid hole 11, so that as the floating plate 10 moves downward, the plugs 15 are gradually pushed out of the lower liquid hole 11, and the lower liquid hole 11 can continuously supply the glue liquid to flow out during the process; in particular, the provided floating plate 10 can be made of a lighter material, such as a foam board, a plastic board, etc.

[0026] like Figure 1 , 3As shown in FIG. 4 , a rubber coating layer 17 is fixedly wrapped around the rubber coating roller 2 , and a grid pattern 18 is arranged on the outer wall of the rubber coating layer 17 , so that the glue can be better adhered to the rubber coating layer 17 and then transferred to the base layer 3 .

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
