Description

Technical Field

[0001] The utility model relates to the technical field of kraft paper processing, in particular to a glue spraying device for kraft paper processing. Background Art

[0002] Kraft paper is a tough, durable paper that gets its name from its appearance and some physical properties that are similar to cowhide. It is widely used in many fields due to its high strength, high toughness and good water resistance.

[0003] During the processing of kraft paper, glue spraying is required to improve its waterproof, moisture-proof, oil-proof and other functions to meet the needs of various packaging protection fields. Gluing is a process of evenly coating adhesive on kraft paper. The type of adhesive can be selected according to actual needs, such as water-based glue, pressure-sensitive adhesive, hot melt adhesive, etc. Through gluing, kraft paper can more effectively protect the packaging items, increase the added value of the product, and broaden its application field, which requires a glue spraying device.

[0004] According to the announcement number: CN209735841U, a glue spraying device for processing waterproof kraft paper is disclosed, including a carrier plate, both sides of the bottom of the carrier plate are fixedly connected with support legs, the bottom of the inner side of the support leg is laterally fixedly connected with a cross plate, both sides of the top of the carrier plate are fixedly connected with support plates, and the top of the support plate is fixedly connected with a fixed plate. The utility model solves the problem that the nozzle height of the existing glue spraying device is fixed and cannot be adjusted according to the size of the paper by setting the carrier plate, support legs, cross plates, support plates, fixed plates, glue tanks, connecting pipes, glue pumps, hoses, sleeves, limit blocks, sleeve rods, slots, lifting plates, nozzles, frames, clamping rods, sliders, slides, springs, pull rods and conveying devices. The glue spraying device for processing waterproof kraft paper has the advantage of adjustable nozzle height, improves the glue spraying efficiency of kraft paper, and shortens the production cycle of kraft paper.

[0005] Based on the search of the above patents and in combination with the equipment in the prior art, it was found that when used, the above equipment can solve the problem that the height of the nozzle of the existing spraying device is fixed and the height of the nozzle cannot be adjusted according to the size of the paper, which reduces the spraying efficiency of kraft paper and prolongs the production cycle of kraft paper.

[0006] However, in actual use, the above-mentioned equipment adopts a block and a slot to adjust the height of the nozzle to adapt to different heights. After a period of time, the block and the slot are worn out, resulting in the nozzle being not stable enough when spraying glue. In addition, the above-mentioned equipment can only spray glue on one side of kraft paper, but not on both sides, thereby reducing work efficiency and having certain limitations. For this reason, we propose a new glue spraying device for kraft paper processing. Utility Model Content

[0026] As a technical optimization scheme of the utility model, by setting a feeding mechanism 8, when the operator needs to spray glue on kraft paper, the operator inserts the kraft paper roll into the surface of the discharge rod 83, and then the operator wraps one end of the kraft paper around the surface of the receiving rod 84. The operator rotates the receiving rod 84 to drive the kraft paper roll on the surface of the discharge rod 83 to be wound and fed, so that the glue spraying head 6 can stably perform the glue spraying work.

A limiting assembly 75 is provided on the front side of the connecting plate 71.

[0037] The working principle and use process of the utility model are as follows: during use, when the operator needs to perform glue spraying, the operator first inserts the kraft paper roll into the surface of the feeding rod 83, and then the operator passes one end of the kraft paper through the inner side of the limiting rod 9 and then winds it around the surface of the receiving rod 84, so that the kraft paper is suspended and parallel to a straight line. The operator starts the glue suction pump 3, so that the input end of the glue suction pump 3 extracts the glue inside the glue barrel 2 to the output end, and the output end diverts the glue through the three-way joint 4 and then transports it to the inside of the connecting hose 5, and then the glue inside the connecting hose 5 is transported to the inside of the glue spraying head 6, and then the glue spraying head 6 sprays glue on the kraft paper, and the operator rotates the receiving rod 84 to drive The kraft paper roll on the surface of the discharge rod 83 is wound and fed, so that the glue spraying head 6 can stably perform the glue spraying work, which ensures double-sided glue spraying and improves the glue spraying efficiency. When the operator needs to spray glue on kraft papers of different specifications, the operator rotates the bidirectional screw rod 73 forward or reversely to drive the connecting block 72 to move closer to or away from each other, and then the movable connecting block 72 drives the connecting plate 71 to move through the limiting rod 752 and the limiting hole 751, so that the movable connecting plate 71 drives the glue spraying head 6 to move the kraft paper closer to or away from each other, thereby completing the adjustment of the glue spraying of kraft papers of different specifications, and improving the convenience of adjustment for the operator.

After a period of time, the wear between the card block and the card slot is large, resulting in the nozzle being not stable enough when spraying glue, and the above-mentioned equipment can only spray glue on one side of the kraft paper, and cannot spray glue on both sides, thereby reducing the work efficiency and having certain limitations.
