Description

Technical Field

[0001] The invention relates to the technical field of bag production, and in particular to a trimming device for bag production and processing. Background Art

[0002] Luggage is a general term for various bags used to carry things, including general shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, satchels, waist bags and various trolley cases, etc. Trolley cases, as a subdivision of luggage, refer to suitcases with a pull rod and wheels, which are widely used because of their convenience. Common trolley cases are mostly made of plastic materials. In order to improve the aesthetics of the case, the four corners of the case are usually set in an arc shape.

[0003] When processing the box, trimming equipment is required to trim the outer wall of the box to remove the excess material on the outer wall of the box. During the trimming process, the box is trimmed continuously by controlling the position of the trimming knife, and the trimming knife needs to always fit the box wall during the trimming process. Due to the arc structure of the four corners of the box, it is difficult for the trimming knife to always fit the outer wall of the box when it moves. When trimming the four corners of the box, manual adjustment of the position of the box and the trimming knife is required. The above operations will affect the smoothness of the trimming process and increase the trimming time of the box.

[0004] In order to ensure the quality of the box trimming during the trimming process, the box needs to be fixed by a fixing mechanism to prevent the box from moving. The fixing mechanism of existing trimming equipment usually directly presses and fixes the middle of the box.

In the initial state, the limit baffle 3 and the moving block 1 are both arranged close to the end of the guide slide bar 33 to avoid interference with the lifting path of the fixed box 4. The working principle is as follows: (1) Place the box 40 to be trimmed at the center of the workbench 28, start the expansion motor 36, and drive the drive gear 37 to rotate. The drive gear 37 engages with the saw teeth 38 on the slide plate 6. Under the action of the rotating drive gear 37, the slide plate 6 is driven to slide along the slide groove 5. The slide plate 6 drives the fixed plate 7 to move away from the side wall of the fixed box 4 until the fixed plate 7 moves to the top of the inner wall of the box 40. The fixed box 4 is driven downward by the pressing cylinder 29, and the fixed box 4 drives the fixed plate 7 to move downward synchronously with it. The fixed box 4 is pressed on the center of the box body 40, and the four groups of fixed plates 7 are pressed on the positions close to the four side walls of the box body 40 respectively. Under the cooperation of the fixed box 4 and the fixed plates 7, the boxes 40 of different sizes can be stably pressed and fixed. (2) After the box body 40 is fixed, the position adjustment motor is first started, and the position adjustment motor drives the position adjustment screw 32 to rotate. Under the driving of the position adjustment screw 32 and the cooperation of the guide slide 33, the moving block 1 is driven to the middle position of the guide slide 33; the limit adjustment motor 35 is started to rotate forward, and the limit adjustment motor 35 drives the limit adjustment screw 34 to rotate. Under the driving of the limit adjustment screw 34 and the guiding action of the guide slide 33, the limit baffle 3 is driven to move, and the limit baffle 3 is moved to the inner side of the side wall of the box body 40. The specific adjustment position of the limit baffle 3 is: when the moving block 1 moves to contact with the limit baffle 3, the trimming knife 2 just fits the outer wall of the box body 40; (3) Start the lifting cylinder 10, and the trimming knife 2 is driven down by the action of the lifting cylinder 10, so that the trimming knife 2 is in contact with the outer wall of the box body 40; start the position driving motor 31, and the position driving motor 31 drives the position adjusting screw 32 to rotate, and drives the moving block 1 to move under the driving action of the position adjusting screw 32 and the guiding action of the guide slide bar 33. When the moving block 1 moves to contact with the limit baffle 3, it means that it has moved to the corner of the box body 40; when the moving block 1 contacts with the limit baffle 3, the first proximity switch 18 and the second proximity switch 19 are driven at the same time, and the second proximity switch 19 controls the electromagnet 16 to be energized. The electromagnet 16 magnetically attracts the iron sheet 17, driving the first proximity switch 18 away from the limit baffle 3, thereby realizing the inching control of the proximity switch; When the proximity switch is inching controlled, the rotating motor 12 is driven to perform a short single-circle rotation, the rotating motor 12 drives the driving gear 20 to rotate, the driving gear 20 is meshed with the driven gear 21 to drive the rotating shaft 13 to rotate, the rotating shaft 13 drives the rotating plate 14 to rotate, the free end of the rotating plate 14 moves in an arc path, and the free end of the rotating plate 14 drives the trimming knife 2 to move in an arc path, so as to trim the corner arc of the box body 40; Through the above-mentioned trimming action, the box body 40 does not need to be manually adjusted, and the box body 40 can also be trimmed continuously.
