Description

Technical Field

[0001] This utility model relates to the field of adhesive application equipment technology, and in particular to an adhesive application equipment for gluing irregularly shaped boxes. Background Technology

[0002] Irregularly shaped boxes are a type of paper box that serves as a protective packaging for products. In essence, irregularly shaped boxes are paper boxes, and during their production and processing, adhesive is applied to the surface of the cardboard (such as decorative and support layers) to bond and combine different types of cardboard together.

[0003] Current gluing devices for gluing cardboard boxes have a fixed length of gluing roller. However, the width of the cardboard for irregularly shaped boxes varies. When gluing narrower cardboard, glue is wasted on the rollers where it does not contact the cardboard, and dust from the environment easily adheres to the rollers, affecting subsequent gluing operations. When gluing wider cardboard, it is often impossible to glu the entire cardboard in one go, requiring adjustments and repeated gluing operations, which is cumbersome, inflexible, and impractical.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Please refer to Figures 1 to 5 Example 1:

[0027] This utility model proposes a gluing device for gluing irregularly shaped boxes, including: a conveying assembly 1 and a gluing assembly; the conveying assembly 1 includes a conveyor belt 101, a mounting bracket 102 and a lifting push rod 103, the mounting bracket 102 is fixedly installed on the side of the conveyor belt 101, and the lifting push rod 103 is fixedly installed on the top of the mounting bracket 102; the gluing assembly consists of a main gluing mechanism 2 and a secondary gluing mechanism 3;

[0028] The main glue application mechanism 2 includes a mounting base 201, a glue supply seat a202, a main glue application roller 203, and a drive motor 204. The mounting base 201 is fixedly installed at the bottom end of the lifting push rod 103, and the glue supply seat a202 is fixedly installed inside the mounting base 201. The main glue application roller 203 is rotatably connected to the bottom of the mounting base 201, and the drive motor 204 is fixedly installed on the side of the mounting base 201. The auxiliary glue application mechanism 3 includes an extension push rod 301, a glue supply seat b302, and an extension... The glue-applying roller 303 and drive shaft 304, and the extension push rod 301 are fixedly installed on the side of the mounting base 201. One end of the push rod of the extension push rod 301 is fixedly installed on the side of the glue supply seat b302. The glue supply seat b302 is inserted into the bottom of the mounting base 201, and the extension glue-applying roller 303 is rotatably connected to the bottom of the glue supply seat b302. The drive shaft 304 is rotatably connected to the side of the mounting base 201. The main glue-applying roller 203 and the extension glue-applying roller 303 are separated from each other and do not contact each other.

[0029] The drive motor 204's shaft is connected to the main coating roller 203's shaft, and the main coating roller 203 and drive shaft 304 are connected via a sprocket and chain drive. The extended coating roller 303 has a synchronization groove 3031 inside, and one side of the drive shaft 304 has a regular polygonal cross-section. The polygonal section of the drive shaft 304 is inserted into the synchronization groove 3031. In use, the conveyor belt 101 can transport the cardboard, and when the cardboard passes under the coating assembly, the coating assembly can apply glue to the cardboard surface. The lifting push rod 103 can control the height of the coating assembly, so that when the cardboard passes under the coating assembly... When the paper is in use, the lifting push rod 103 can move down to bring the main gluing roller 203 and the extended gluing roller 303 into contact with the paperboard surface, thereby realizing the gluing operation on the paperboard. The main gluing roller 203 and the extended gluing roller 303 can rotate synchronously to assist in the conveying of the paperboard and avoid jamming. The drive motor 204 can drive the main gluing roller 203 to rotate. When the main gluing roller 203 rotates, it can drive the drive shaft 304 to rotate through the sprocket chain. When the drive shaft 304 rotates, it can drive the extended gluing roller 303 to rotate through the synchronization groove 3031. The main gluing roller 203 and the extended gluing roller 303 can rotate synchronously and in the same direction, thereby assisting in the paper conveying operation and ensuring stable operation.

[0030] Both glue supply seats a202 and b302 are equipped with glue supply channels 3021. They are connected to external glue supply equipment via pipes. Glue supply seat a202 applies glue to the body of the main coating roller 203, while glue supply seat b302 applies glue to the body of the extended coating roller 303. During use, the effective coating width of the coating assembly can be adjusted by the extension push rod 301. When the extension push rod 301 extends or retracts, it moves the glue supply seat b302 and the extended coating roller 303, thus changing the positional relationship between them. When the main coating roller 203 and the extended coating roller 303 are used flush, the coating width is at its minimum. When they are used alternately, the coating width is extended, allowing for coating operations on paperboards of different widths. This provides flexibility and convenient adjustment.

[0031] The mounting base 201 has a sealing baffle 2011 inside, which is inserted into the glue supply channel 3021 of the glue supply base b302. When the main coating roller 203 and the extended coating roller 303 are used flush, the sealing baffle 2011 completely blocks the glue supply channel 3021 of the glue supply base b302. In use, the glue supply bases a202 and b302 can supply glue to the roller bodies of the main coating roller 203 and the extended coating roller 303 respectively for coating. The main coating roller 203 is located on one side of the discharge direction, and the extended coating roller 303 is located on one side of the feed direction. This design allows the main coating roller 203 and the extended coating roller 303 to be used flush and prevents slippage. The glue supply channel 3021 of the glue supply base b302... When 21 is completely blocked, the extended coating roller 303 will not receive glue, thus avoiding repeated glue application to the paperboard by the main coating roller 203 and the extended coating roller 303. When the main coating roller 203 and the extended coating roller 303 are used alternately, the part of the glue supply channel 3021 of the glue supply seat b302 that is wider than the main coating roller 203 will automatically open. This part will not be blocked by the blocking baffle 2011, so the glue can be applied to the outside of the extended coating roller 303 through this part for glue application. In other words, when extended, the extended coating roller 303 will only receive glue on the roller body located outside the main coating roller 203. This ensures complete glue application to the paperboard while avoiding repeated glue application to the paper, resulting in stable operation.

[0032] The glue supply seat b302 has a T-shaped track block 3022 on its top, and the mounting base 201 has a track groove 2012 inside. The track block 3022 is inserted into the track groove 2012. The track groove 2012 can limit the movement trajectory of the glue supply seat b302 during movement adjustment through the track block 3022, thereby avoiding the phenomenon of device jamming and failure, and ensuring stable use.

[0033] The working principle of this embodiment is as follows: The conveyor belt 101 can realize the conveying operation of the cardboard. When the cardboard passes the bottom of the gluing assembly, the gluing assembly can perform a gluing operation on the surface of the cardboard. The lifting push rod 103 can control the working height of the gluing assembly. So when the cardboard passes the bottom of the gluing assembly, the lifting push rod 103 can move down to make the main gluing roller 203 and the extended gluing roller 303 abut against the surface of the cardboard, thereby realizing the gluing operation of the cardboard. The main gluing roller 203 and the extended gluing roller 303 can rotate synchronously to assist the conveying of the cardboard and avoid jamming. The drive motor 204 can drive the main gluing roller 203 to rotate. When the main coating roller 203 rotates, it drives the drive shaft 304 to rotate via a sprocket and chain. The drive shaft 304, in turn, drives the extended coating roller 303 to rotate via a synchronous groove 3031. The main coating roller 203 and the extended coating roller 303 rotate synchronously and in the same direction, thus assisting in the paper feeding operation. The effective coating width of the coating assembly can be adjusted via the extension push rod 301. When the extension push rod 301 extends or retracts, it moves the glue supply seat b302 and the extended coating roller 303, thereby changing the positional relationship between the main coating roller 203 and the extended coating roller 303. When the main coating roller 203 and the extended coating roller 303 are used flush... At this point, the coating width is at its minimum. When the main coating roller 203 and the extended coating roller 303 are used alternately, the coating width can be extended, thereby enabling coating operations on paperboards of different widths. Glue supply seats a202 and b302 can supply glue to the roller bodies of the main coating roller 203 and the extended coating roller 303 respectively for coating. The main coating roller 203 is located on one side of the discharge direction, and the extended coating roller 303 is located on one side of the feed direction. This design allows the main coating roller 203 and the extended coating roller 303 to be used flush. The glue supply channel 3021 of the glue supply seat b302 is completely blocked, and the extended coating roller 303 will not receive glue. To ensure proper glue supply and prevent repeated gluing operations on the paperboard by the main gluing roller 203 and the extended gluing roller 303, when the main gluing roller 203 and the extended gluing roller 303 are used alternately, the portion of the glue supply channel 3021 of the glue supply seat b302 that is wider than the main gluing roller 203 will automatically open. This portion will not be blocked by the blocking baffle 2011, allowing the glue to be applied to the outside of the extended gluing roller 303 through this portion. In other words, when the extended roller is used, the extended gluing roller 303 will only receive glue on the roller body located outside the main gluing roller 203. This ensures complete gluing operations on the paperboard while avoiding repeated gluing operations on the paper.
