Description

Technical Field

[0001] The utility model relates to the technical field of fan coil units, in particular to an automatic box gluing machine for packaging boxes. Background Art

[0002] Folder gluer is an automated packaging equipment, which is mainly used to automate the folding and gluing process of paper boxes to achieve efficient packaging of paper boxes. In the packaging and printing industry, it is the last process of packaging box processing. It mainly folds and glues the printed and die-cut cardboard, thus replacing the manual gluing method, reducing labor costs and improving efficiency.

[0003] At present, when using the folder gluer, intermittent processing is often encountered, which may be a break in the middle or a delay in feeding. During this process, the paint wheel may be stuck with paint. Once solidified, it may cause damage to the paper box. The existing improvement method is to design the paint wheel into a structure that is easy to disassemble. For example, a folder gluer disclosed in patent number CN214056629U cleans and replaces the disassembled paint wheel to ensure that the paint wheel remains clean, so that no solidified paint is left on the paint wheel, and the paint effect is guaranteed.

[0004] However, the investigation found that this design method still has certain shortcomings and room for improvement. The paint wheel is installed through an elastic snap-on method, which makes it not stable enough. There may be slight shaking between the paint wheel and the motor shaft, which may affect the paper box. At the same time, when processing is required and glue solidification is found, it needs to be cleaned after removal, which undoubtedly wastes processing time and delays work efficiency.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and an automatic box gluing machine for packaging boxes is proposed. Utility Model Content

Specific implementation mode

[0027] The following further describes in detail the implementation mode of the present utility model in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0028] As Figures 1 - 8 shown, it includes two transport platforms 1, a conveyor belt 11 is installed between the transport platforms 1, a support plate 12 is fixed on the side wall of one transport platform 1, a box pasting rack 13 is connected to the top of the support plate 12 in a lifting manner, a coating wheel 14 is rotatably connected to one side of the box pasting rack 13, two synchronization heads 16 are rotatably arranged on the inner wall of the box pasting rack 13, and a drive belt 17 is connected between the synchronization heads 16. The synchronization head 16 at the upper end is butted against the rotating shaft of the coating wheel 14, and a spline 18 is fixed on one side of the synchronization head 16 at the lower end. The cleaning box 2 and the paste box 3 are installed on the top of the transport platform 1 through the moving component 4. A chemical fiber brush 21 is installed on the rotating shaft of the inner wall of the cleaning box 2, and the rotating shaft of the chemical fiber brush 21 passes through the cleaning box 2 and is butted against the spline 23. The external spline 23 is engaged with the spline sleeve 22. The spline sleeve 22 can be sleeved outside the spline 18 through translation to form an engagement. The box pasting rack 13 is designed in an inverted "U" shape and one end is designed shorter. The coating wheel 14 is installed on the shorter end face. One side of the longer end face of the box pasting rack 13 is provided with a motor 15, and the motor shaft of the motor 15 is butted against the synchronization head 16 at the upper end. The bottom surface of the end of the box pasting rack 13 where the motor 15 is installed is fixed on the lifting plate 110, and two electric push rods 19 are connected between the bottom surface of the lifting plate 110 and the support plate 12.

[0029] As described above, by designing an upgradable box gluing rack 13, a synchronizer 16, a drive belt 17, a spline one 18, a cleaning box 2, a chemical fiber brush 21, a spline sleeve 22 and a spline two 23, when performing box gluing processing, at the beginning, the glue box 3 is located below the coating wheel 14, and the cleaning box 2 is located on one side of the glue box 3. Then, two electric push rods 19 are started to drive the lifting plate 110 to move, and the box gluing rack 13 on the support plate 12 is lowered. The coating wheel 14 moves downward to enter the glue box 3 and contact the glue. Then, during operation, the paper box is transported on the conveyor belt 11. The first motor 15 is started to drive the coating wheel 14 to rotate through the synchronizer 16. A pressing wheel is installed on the side wall of the box gluing rack 13 above the coating wheel 14. Then, the edge of the glue of the paper box will pass between the coating wheel 14 and the pressing wheel to complete gluing. When the work is interrupted for special reasons and it is found that the glue on the coating wheel 14 has solidified when restarting work, the box gluing rack 13 is raised, and the cleaning box 2 and the glue box 3 are translated together on the top of the transport table 1 through the moving assembly 4. At this time, the cleaning box 2 is located below the coating wheel 14. The coating wheel 14 is lowered into it and is in contact with the bristles of the chemical fiber brush 21. Then, the spline sleeve 22 engaged with the outside of the spline two 23 is pulled outwards. The spline sleeve 22 is sleeved on the spline one 18. At this time, the spline two 23, the spline one 18 and the rotating shaft of the chemical fiber brush 21 rotate synchronously. Finally, the first motor 15 is started, and the two synchronizers 16 rotate in the same direction together through the drive belt 17. The spline one 18 rotates, so that the chemical fiber brush 21 and the coating wheel 14 rotate in the same direction and at the same speed. However, the top of the chemical fiber brush 21 and the bottom of the coating wheel 14 rotate in opposite directions. This enables the chemical fiber brush 21 to brush off the hardened glue on the coating wheel 14 when they come into contact, completing automatic cleaning. After the cleaning is completed, the glue box 3 is moved below the coating wheel 14. In this way, there is no need to design unstable detachable elastic buckles and other structures to install the coating wheel 14, nor to remove it for manual cleaning, effectively improving the work efficiency and the stability of box gluing.

[0030] A ring plate 27 is fixed to the outer wall of the end of the spline two 23 close to the cleaning box 2. A small screw rod 26 is fixed to one side of the ring plate 27. A threaded ring block 28 is threadedly connected to the small screw rod 26. A square block 25 is fixed to the bottom of the spline sleeve 22. The square block 25 is passed through by the small screw rod 26 and they do not contact each other.

[0031] As described above, in terms of optimizing the operation stability of the chemical fiber brush 21, the square block 25 moves together with the spline sleeve 22. When cleaning, the spline sleeve 22 moves and is sleeved on the spline one 18. To prevent it from disengaging, the ring plate 27 can be pinched by hand, and the threaded ring block 28 on the small screw rod 26 is rotated to make it fit with the square block 25, so that the spline sleeve 22 cannot be reset, and the spline sleeve 22 is kept in stable engagement with the spline two 23 and the spline one 18. It should be noted that at this time, the spline sleeve 22 is in contact with the side wall of the synchronizer 16.

[0032] A scraper 24 is fixed to the inner wall of the cleaning box 2, and the scraper 24 is in contact with the top of the chemical fiber brush 21. On one side of the cleaning box 2, there is a socket below the scraper 24, and a filter plate 29 is inserted into the socket. At one end of the filter plate 29, two plug blocks are symmetrically fixed. The plug blocks can be inserted into the sockets opened on the inner wall of the cleaning box 2. The cleaning box 2 is filled with clean water and the water level is below the filter plate 29. Three electric heating tubes 212 are arranged below the water level inside the cleaning box 2. A micro pump 210 is installed on the side wall of the cleaning box 2. The water inlet pipe of the micro pump 210 is inserted into the cleaning box 2, and the outlet pipe 211 of the micro pump 210 is located above the cleaning box 2.

[0033] In the above, in the further optimization of cleaning, during the cleaning process, the scraper 24 is convenient for scraping off the glue adhered to the chemical fiber brush 21 due to cleaning. The electric heating tubes 212 are started at the beginning of the work to increase the water temperature. The micro pump 210 is started. The outlet pipe 211 is located above the cleaning box 2, and during cleaning, it is located on one side of the coating wheel 14. Then the hot water sprayed out will fall on the coating wheel 14. The glue is softened by the hot water, making the glue easier to remove, improving the cleaning efficiency. At the same time, some of the water sprayed out will also fall on the chemical fiber brush 21, making the glue on the brush easier to fall off. The sewage can be filtered through the filter plate 29. It should be noted that for tiny particles such as colloids, the filtering effect of the filter screen is poor, but it can still play a certain filtering role and can meet the use requirements in actual applications, avoiding the glue-containing sewage from flushing directly into the water. At the same time, there is a drain pipe on one side of the lower end of the cleaning box 2.

[0034] The moving component 4 includes a second motor 41 installed in the recess on the top of a transport table 1. The second motor 41 is connected to a lead screw 42 on the inner wall of the transport table 1. A moving block 43 is threadedly connected to the lead screw 42. The top of the moving block 43 is connected to the cleaning box 2 and the paste box 3 through two convex blocks. On the top of the transport table 1 where the moving component 4 is installed, a cover plate 111 is nailed at the recess, and there are openings on the cover plate 111 for the two convex blocks on the top of the moving block 43 to pass through, and the two convex blocks slide in the openings.

[0035] In the above, by designing the moving component 4, when adjusting the positions of the cleaning box 2 and the paste box 3 for cleaning or pasting the box, start the second motor 41 to make the lead screw 42 rotate, and the moving block 43 can move back and forth, and then can conveniently and efficiently drive the cleaning box 2 and the paste box 3 to move, which is very convenient. The cover plate 111 is convenient for limiting the two convex blocks and can be disassembled for maintaining the internal lead screw 42 or the second motor 41, which is very practical. It should be noted that the cleaning box 2 and the paste box 3 are installed with moving wheels at the bottom, which are convenient for support and movement.

[0036] The embodiments of the present utility model are given for purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to better explain the principles of the present utility model and its practical applications, and to enable those of ordinary skill in the art to understand the present utility model so as to design various embodiments with various modifications suitable for specific purposes.
