Description

Technical Field

[0001] The utility model belongs to the technical field of paper production, in particular to a glue adding device used for waterproofing and moisture-proofing paper. Background Art

[0002] During the production process of paper, in order to prevent the paper from absorbing water or getting damp and to make the paper waterproof and moisture-proof, a treatment process is added to the surface of the paper. Glue is mainly applied to the surface of the paper. After the glue is added, the paper is protected by the glue. The existing equipment for applying glue to paper has achieved double-sided gluing of paper. For example, patent application No. 202220471350.6 discloses a gluing device for paper surface treatment, including a frame, a gluing roller, an extrusion roller and a glue box. The two sets of gluing rollers are set up so that after the first set of gluing rollers applies glue to the back of the paper, the paper passes around the second set of extrusion rollers so that the front side of the paper abuts against the second set of gluing rollers, thereby achieving gluing on both sides of the paper. The paper is then wound around the third guide roller and transported to the next workstation, so that the uniformity of the gluing on the paper can be improved, the waterproofness of the paper can be improved, the chance of water permeability of the paper during writing can be reduced, and subsequent writing work is convenient.

[0003] Although the above-mentioned solution for gluing paper can achieve double-sided gluing of paper, the solution has the following defects: first, the paper needs to be wound on two sets of gluing rollers and multiple guide rollers, which not only makes the equipment structure more dispersed and the equipment larger, but also, for some smaller-sized papers, their size is not enough to be wound on two sets of gluing rollers, making it inconvenient to be used for smaller-sized papers, resulting in a smaller scope of application of the equipment. Secondly, the distance between the squeezing roller and the gluing roller is fixed, resulting in it being only applicable to papers of a specific thickness, and it is inconvenient to be used for gluing papers of different thicknesses, further limiting the scope of application of the equipment. Utility Model Content

[0004] In order to solve the problems existing in the prior art, the utility model provides a gluing device for waterproofing and moisture-proofing paper. The first and second rubber rollers cooperate to not only apply glue to the surfaces of both sides of the paper, but also are suitable for smaller-sized paper, thereby improving the applicability of the equipment. The lower glue box is driven to move by the electric push rod 1, thereby adjusting the distance between the first and second rubber rollers, making it convenient for the equipment to apply glue to paper of different thicknesses, further improving the applicability of the equipment. In addition, the structure of the entire solution of the equipment is relatively centralized and integrated, which can reduce the volume of the equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] The top of described rubber roller is positioned at lower glue box, and the bottom of described rubber roller is positioned at lower glue box, and the bottom of described rubber roller is positioned at lower glue box.

[0007] Furthermore, a bracket is fixedly connected to the rear side of the mounting plate, the bracket is U-shaped, the upper gear is located inside the bracket, the side of the bracket is fixedly connected to a motor, and the output shaft of the motor is fixedly connected to the shaft end of the rubber roller 2.

[0008] Furthermore, a limiting block is fixedly connected to the front side of the mounting plate, and the limiting block is located above the gluing box.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] 1. The upper glue box is driven to move by the electric push rod 2, so that the glue roller 2 can adhere to glue when rotating. With the help of two gear transmissions, the glue roller 1 rotates in the opposite direction with the glue roller 2 and adheres to glue. Therefore, the cooperation between the glue rollers 1 and 2 can not only apply glue to the surfaces of both sides of the paper, but also be applicable to smaller-sized paper, thereby improving the scope of application of the equipment. The lower glue box is driven to move by the electric push rod 1, thereby adjusting the distance between the glue rollers 1 and 2, making it easy for the equipment to apply glue to papers of different thicknesses, further improving the scope of application of the equipment. In addition, the structure of the entire solution of this equipment is relatively centralized and integrated, which can reduce the volume of the equipment compared with the existing equipment with a more dispersed structure.

[0011] 2. The motor installed on the bracket is used to drive the first rubber roller to rotate, and the limit block is used to limit the movement position of the glue box to avoid the glue box moving too far away from the second rubber roller, which will cause the bristles to be unable to contact the second rubber roller and cause the glue to flow directly.

[0021] See attached Figure 1-6As shown, a gluing device for waterproofing and moisture-proofing paper includes a mounting plate 1, a motorized push rod 2 is fixedly connected to the bottom of the front side of the mounting plate 1, a lower glue box 3 is fixedly connected to the telescopic end of the motorized push rod 2, the top of the lower glue box 3 is provided with an opening, and the front and rear sides of the top of the lower glue box 3 are fixedly connected to support plates 4, a rubber roller 5 is rotatably connected between the two support plates 4, the lower side of the rubber roller 5 is located in the lower glue box 3, the front side of the mounting plate 1 is rotatably connected to a rubber roller 2 6 located above the rubber roller 5, and the front side of the mounting plate 1 is provided with a motorized push rod 2. The top is fixedly connected with an electric push rod 2 7, and the telescopic end of the electric push rod 2 7 is fixedly connected with a gluing box 8. The top and bottom of the gluing box 8 are provided with openings. The opening at the bottom of the gluing box 8 is arc-shaped and adapted to the curvature of the rubber roller 2 6. The bottom of the gluing box 8 is fixedly connected with a number of bristles. A through groove 9 is provided on the mounting plate 1 at the rubber roller 1 5, and the axial end of the rubber roller 1 5 passes through the through groove 9. The axial ends of the rubber roller 1 5 and the rubber roller 2 6 are fixedly sleeved with a gear 10 located on the rear side of the mounting plate 1, and the two gears 10 are engaged.

[0022] The rear side of the mounting plate 1 is fixedly connected to a bracket 11, which is U-shaped. The upper gear 10 is located inside the bracket 11, and the side of the bracket 11 is fixedly connected to a motor 12. The output shaft of the motor 12 is fixedly connected to the shaft end of the rubber roller 2 6.

[0023] The front side of the mounting plate 1 is fixedly connected to a limit block 13, which is located above the gluing box 8. The installation position of the limit block 13 is related to the length of the bristles, that is, after the gluing box 8 contacts the limit block, the bristles can still contact the rubber roller 2 6.

[0024] Working principle: In the present invention, before gluing, the distance between the rubber roller 1 5 and the rubber roller 2 6 is adjusted in advance according to the thickness of the paper. Specifically, the electric push rod 1 2 drives the lower glue box 3 to move, and the rubber roller 1 5 moves synchronously with the lower glue box 3 through the support plate 4 until the distance between the rubber roller 1 5 and the rubber roller 2 6 is adjusted appropriately. The appropriate standard is that after the paper is placed, both sides of the paper will be clamped by the rubber roller 1 5 and the rubber roller 2 6. It should be noted that the movement of the rubber roller 1 5 will drive a gear 10 to move. Therefore, the premise of the movable range is to ensure that the gear teeth of the two gears 10 are engaged and can still be in the engaged transmission state. There is glue in both the upper glue box 8 and the lower glue box 3. When processing the paper, the motor 12 is started to drive the rubber roller 2 6 to rotate, and the two gears 10 are used to transmit the rubber roller 1 5 in the opposite direction. The rubber roller 1 5 rotates in the opposite direction. During rotation, it contacts the glue in the lower glue box 3, so that glue is attached to the rubber roller 5, and the electric push rod 2 7 is started to drive the upper glue box 8 to move upward, and the bottom of the upper glue box 8 is no longer in contact with the rubber roller 2 6, and only the bristles are in contact with the rubber roller 2 6. At this time, the glue in the upper glue box 8 flows out from the lower opening, and the bristles are distributed at the edge of the opening to form a circle to block the glue, and then due to the existence of tension, the glue only contacts the surface of the rubber roller 2 6 and will not overflow from the gap between the bristles. In this way, glue will also be attached to the rotating rubber roller 2 6, and one end of the paper is inserted into the gap between the rubber roller 1 5 and the rubber roller 2 6. The paper moves to the other side with the traction of the rubber roller 1 5 and the rubber roller 2 6. During the movement, the surfaces of the upper and lower sides of the paper contact the glue on the rubber roller 1 5 and the rubber roller 2 6, so that double-sided gluing of the paper can be achieved.

[0025] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
