Description

Technical Field

[0001] This utility model relates to the field of bag making technology, and in particular to an automatic bag making mechanism for kraft paper bags. Background Technology

[0002] When making kraft paper bags, a cutting mechanism is needed to cut rolls of kraft paper into segments. The cutting blades wear down gradually during use and require periodic disassembly and sharpening. Currently, the cutting blades are fixed with screws, requiring manual removal with a specific screwdriver each time, which is cumbersome. Therefore, there is an urgent need to develop an automated kraft paper bag making mechanism that facilitates the installation and disassembly of the cutting blades, saving manpower, to overcome the shortcomings of current applications and meet current needs. Utility Model Content

[0003] The purpose of this invention is to provide an automatic kraft paper bag making mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An automatic kraft paper bag making mechanism includes a worktable, a kraft paper feeding mechanism, an electric telescopic rod, a lifting plate, a cutting blade, and a quick-assembly / disassembly mechanism. The kraft paper feeding mechanism is installed on the right end of the worktable. A guide roller is rotatably connected to the left side of the kraft paper feeding mechanism on the worktable. An auxiliary conveying mechanism is installed to the left of the guide roller on the worktable. A cutting table is fixed to the left of the auxiliary conveying mechanism on the worktable. An electric telescopic rod is fixed to both sides of the cutting table, and the telescopic ends of the electric telescopic rods are fixed to the lifting plate. A connecting block is fixed to both sides of the cutting blade by screws. A quick-assembly / disassembly mechanism that inserts into the connecting blocks is installed on the lifting plate. The quick-assembly and disassembly mechanism includes: a bidirectional screw, a first external thread, a second external thread, a first threaded sleeve, a second threaded sleeve, a plug-in block, and a rotating handle. The bidirectional screw is rotatably connected to the upper side of the lifting plate. The left half of the bidirectional screw is provided with a first external thread, and a first threaded sleeve is installed on the outer side of the first external thread. The right half of the bidirectional screw is provided with a second external thread, and a second threaded sleeve is installed on the outer side of the second external thread. A plug-in block penetrating the lifting plate is fixed to the lower side of both the first and second threaded sleeves. The plug-in block is provided with a slot for locking the plug-in block. The first and second external threads have opposite directions of rotation. A rotating handle is fixed to the right end of the bidirectional screw.

[0006] Preferably, the plug-in block is slidably connected to the lifting plate, and the lifting plate is provided with a sliding groove for the movement of the plug-in block.

[0007] Preferably, the kraft paper feeding mechanism includes: a storage roller, a first motor, a first gear, and a second gear. The first motor is fixed on the worktable, the storage roller is rotatably connected to the worktable, the first gear is fixed on the output shaft of the first motor, and a second gear meshing with the first gear is provided on one side of the first gear. The second gear is fixed on the storage roller.

[0008] Preferably, the auxiliary conveying mechanism includes: a conveying roller, a third gear, and a second motor. Two conveying rollers are rotatably connected to the worktable, and a third gear is fixed on each conveying roller. The two third gears mesh with each other. The second motor is fixed on the worktable, and the output shaft of the second motor is fixed to the conveying roller.

[0009] The beneficial effects of this utility model are as follows: In use, the kraft paper on the storage roller passes under the guide roller and then between two conveying rollers. A first motor drives the storage roller to rotate, conveying the kraft paper outwards. A second motor drives the two conveying rollers to rotate, conveying the kraft paper forward to the cutting table. An electric telescopic rod moves the lifting plate and cutting blade up and down, cutting the kraft paper into segments. After a period of use, one hand rotates the handle to rotate the bidirectional screw, while the other hand holds the cutting blade. The rotation of the bidirectional screw causes the first and second threaded sleeves to move away from each other, moving two insert blocks out of their slots. This allows the cutting blade to be removed for grinding and repair. After grinding and repair, the insert blocks are inserted back into the slots to secure the cutting blade. In summary, this utility model facilitates the installation and removal of the cutting blade, makes grinding and repair easy, and saves manpower. Attached Figure Description

The system comprises a threaded sleeve 905, a plug-in block 906, and a rotating handle 907. A bidirectional screw 901 is rotatably connected to the upper side of the lifting plate 7. The left half of the bidirectional screw 901 has a first external thread 902, and a first threaded sleeve 904 is installed on the outer side of the first external thread 902. The right half of the bidirectional screw 901 has a second external thread 903, and a second threaded sleeve 905 is installed on the outer side of the second external thread 903. A through-hole is fixed to the lower side of both the first threaded sleeve 904 and the second threaded sleeve 905. The connecting block 906 passes through the lifting plate 7. The connecting block 801 is provided with a slot 802 for locking the connecting block 906. The connecting block 906 is slidably connected to the lifting plate 7. The lifting plate 7 is provided with a sliding groove 701 for moving the connecting block 906. The first external thread 902 and the second external thread 903 have opposite rotation directions, so that when the bidirectional screw 901 rotates, the first threaded sleeve 904 and the second threaded sleeve 905 move in opposite directions. The right end of the bidirectional screw 901 is fixed with a rotating handle 907.

[0021] The kraft paper feeding mechanism 2 includes: a storage roller 201, a first motor 202, a first gear 203, and a second gear 204. The storage roller 201 stores kraft paper. The first motor 202 is fixed on the workbench 1. The storage roller 201 is rotatably connected to the workbench 1. The first gear 203 is fixed on the output shaft of the first motor 202. A second gear 204 is provided on one side of the first gear 203 and meshes with it. The second gear 204 is fixed on the storage roller 201. In use, the first motor 202 drives the storage roller 201 to rotate, and the kraft paper is conveyed outward through the storage roller 201.

[0022] The auxiliary conveying mechanism 4 includes: a conveying roller 401, a third gear 402, and a second motor 403. Two conveying rollers 401 are rotatably connected to the worktable 1.

[0024] Working principle: In operation, the kraft paper on the storage roller 201 passes under the guide roller 3 and then between the two conveying rollers 401. The first motor 202 drives the storage roller 201 to rotate, conveying the kraft paper outwards. The second motor 403 drives the two conveying rollers 401 to rotate, conveying the kraft paper forward to the cutting table 5. The electric telescopic rod 6 drives the lifting plate 7 and the cutting blade 8 to move up and down, thus cutting the kraft paper into sections. After a period of use, one hand rotates the handle 907 to drive the bidirectional screw 901 to rotate, while the other hand holds the cutting tool 8. The rotation of the bidirectional screw 901 causes the first threaded sleeve 904 and the second threaded sleeve 905 to move away from each other. The first threaded sleeve 904 and the second threaded sleeve 905 drive the two plug-in blocks 906 to move out of the slot 802, so that the cutting tool 8 can be removed for grinding and repair. After grinding and repair, the plug-in blocks 906 are inserted into the slot 802 to fix the cutting tool 8.
