Description

Technical Field

[0001] The utility model mainly relates to the technical field of paper bag processing, in particular to a gluing tool for the bottom of a paper bag. Background Art

[0002] The paper bag processing process is usually divided into design, raw material preparation, printing, cutting, laminating, punching, bonding and stringing. During the bonding stage, workers generally use hot melt glue or handmade white glue to stick the edges and bottom of the paper bag together to ensure that there is no leakage.

[0003] However, in order to prevent the hot melt adhesive from spilling on the workbench, the workers generally squeeze out the glue by extrusion and then press it manually. However, this will lead to uneven coating, resulting in reduced strength of the paper bag and low bearing strength of the paper bag. Therefore, a coating tool that helps workers to evenly coat the bottom of the paper bag is needed to solve the above problem. Utility Model Content

[0004] The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology. It mainly provides a gluing tool for the bottom of a paper bag, which is used to solve the technical problem raised in the above background technology that at present, in order to avoid hot melt adhesive spilling on the workbench, the staff generally squeezes out the glue by extrusion and then presses it manually, but this situation will lead to uneven coating, resulting in a decrease in the strength of the paper bag and low bearing strength of the paper bag.

[0005] The utility model adopts the following technical solution to solve the above technical problems: a gluing tool for the bottom of a paper bag, comprising a bottom plate, the bottom plate is connected and fixed to a workbench, the top of the rear side of the bottom plate is connected and fixed to a driving box, the middle position of the front side of the driving box is rotatably connected to a laterally arranged glue roller, and guide plates are arranged on both sides of the driving box.

[0006] Preferably, a driving unit is arranged in the driving box, an output end of the driving unit is transmission-connected with a first gear, the first gear is meshed with a second gear, and the second gear is transmission-connected with a rubber roller.

[0007] Preferably, the rubber-attached roller includes a wire mesh ring, an inner ring at one end of the wire mesh ring close to the drive box is fixedly connected to an outer ring at one end of a first connecting tube, the other end of the first connecting tube is rotatably connected to one end of a second connecting tube, the outer ring of the first connecting tube is fixedly connected to the inner ring of the first gear, and the other end of the second connecting tube is connected to a rubber storage box.

[0008] Preferably, a silk screen is arranged on the outer ring of the steel wire mesh ring, one end of the silk screen is clamped with the inner ring of the fixing ring, and the other end of the silk screen is clamped with the inner ring of the sealing cover.

[0009] Preferably, a valve block is arranged in the second connecting pipe, the top of the valve block is connected and fixed to a connecting rod, and the connecting rod passes through the second connecting pipe and the driving box and is connected and fixed to the rotating torque.

[0010] Compared with the prior art, the beneficial effect of the utility model is that the first gear and the second gear are driven by the driving unit, so that the second gear drives the glue-attaching roller to rotate continuously, thereby improving the phenomenon that the glue-attaching roller has poor glue output and uneven glue application during the process of gluing paper bags.

[0011] When the screen printing screen needs to be replaced, in order to prevent glue from continuing to leak from the glue storage box, the valve block connected to it through the connecting rod is rotated by turning the rotating knob, so that the second connecting pipe can be closed, thereby preventing glue from leaking from the glue storage box. At the same time, the valve block is a pancake-shaped valve block, and the connecting pipe can be completely closed or opened by rotating it, and the amount of glue flow can be controlled at the same time.

[0019] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly connected by technicians in the technical field of the present invention. The terminology used in the specification of the present invention is for the purpose of describing specific embodiments and is not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0021] See also Figure 1 and Figure 2 , a gluing tool for the bottom of a paper bag, comprising a rectangular bottom plate 1, the bottom plate 1 is fixed to a workbench by bolts, the top of the rear side of the bottom plate 1 is fixed to a driving box 3 by bolts, the middle position of the front side of the driving box 3 is rotatably connected to a laterally arranged adhesive roller 2, the adhesive roller 2 is used to dispense adhesive and rotate, so that when a worker glues the bottom of the paper bag and the bottom plate of the paper bag, he only needs to slide on the adhesive roller 2 manually. Compared with the original manual foundation, this method is faster and more efficient, and the coating is more uniform, thereby improving the strength of the paper bag and the manufacturing efficiency. Guide plates are arranged on both sides of the driving box 3 4. Through the guide plate 4, the manual operation only needs to push the paper bag against the guide plate 4 and slide it over the glue-attaching roller 2, which is faster. A driving unit 31 is arranged in the driving box 3. The driving unit 31 can be a motor. The output end of the driving unit 31 is connected to the first gear 32 in transmission. The first gear 32 is meshed with the second gear 33. The second gear 33 is connected to the glue-attaching roller 2 in transmission. The first gear 32 and the second gear 33 are driven by the driving unit 31, so that the second gear 33 drives the glue-attaching roller 2 to rotate continuously, thereby improving the phenomenon that the glue-attaching roller 2 has a poor glue-discharging effect and the glue is unevenly applied during the process of gluing the paper bag.

[0022] The glue roller 2 includes a wire mesh ring 23, which plays a supporting role and can cause the glue to flow out slowly. The inner ring of one end of the wire mesh ring 23 close to the drive box 3 is fixedly connected to the outer ring of one end of the first connecting tube 25, and the other end of the first connecting tube 25 is rotatably connected to one end of the second connecting tube 26. The outer ring of the first connecting tube 25 is fixedly connected to the inner ring of the first gear 32, and the other end of the second connecting tube 26 is connected to the glue storage box 28. Glue can be continuously injected into the second connecting tube 26 and the first connecting tube 25 through the glue storage box 28, so that glue continuously flows into the wire mesh ring 23.

[0023] A silk screen 22 is arranged on the outer ring of the steel wire mesh ring 23 , one end of the silk screen 22 is clamped with the inner ring of the fixing ring 21 , and the other end of the silk screen 22 is clamped with the inner ring of the cover 24 . The silk screen 22 can prevent glue from dripping from the steel wire mesh ring 23 , and the glue flowing out of the steel wire mesh ring 23 is always printed on the silk screen 23 .

[0024] A valve block 27 is arranged in the second connecting pipe 26. The valve block 27 is in a pancake shape. The connecting pipe 26 can be completely closed or opened by rotating, and the amount of glue flow can be controlled at the same time. The top of the valve block 27 is connected and fixed to a connecting rod. The connecting rod passes through the second connecting pipe 26 and the driving box 3 and is connected and fixed to a rotating knob 271. When the silk screen 22 needs to be replaced, in order to prevent the glue from continuously leaking from the glue storage box 28, the rotating knob 271 is rotated to cause the valve block 27 connected to it by the connecting rod to rotate, so that the second connecting pipe 26 can be closed, thereby preventing the glue from leaking from the glue storage box 28.

[0025] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
