Description

Technical Field

[0001] The utility model relates to the technical field of a deviation correction and adjustment mechanism for a bag-making machine, in particular to a deviation correction and adjustment mechanism for a bag-making machine. Background Art

[0002] A bag making machine refers to a machine that produces bags from plastic film. During the production process, the film needs to be fed into the machine through conveyor rollers. During the conveying process, it is necessary to ensure that the film does not deviate, otherwise it will directly lead to the inability to carry out correct production. For this reason, a square correction structure needs to be established.

[0003] According to the "A Bag Making Machine Deviation Adjustment Mechanism" with the announcement number "CN219903572U", it is capable of adjusting the distance between the two deviation-correcting cylinders by setting a slider, a second screw, a threaded block and a connecting rod, so that the device can be applied to bag-making materials of different thicknesses and improve the applicability of the device, and can also ensure that the deviation-correcting cylinder is in close contact with the bag-making materials, improve the friction between the deviation-correcting cylinder and the bag-making materials, and ensure the deviation-correcting effect; by setting the first screw, the threaded tube and the limit rod, the horizontal position of the deviation-correcting cylinder can be adjusted, thereby achieving deviation correction of the bag-making materials, and the vertical movement (i.e., adjusting the distance between the two deviation-correcting cylinders) and the horizontal movement of the deviation-correcting cylinder can be achieved through one driving member, which reduces the cost of use and is convenient for promotion. In summary, the beneficial effects of the utility model are: it can not only adjust the distance between the two deviation-correcting cylinders, improve the applicability of the device and ensure the deviation-correcting effect, but also adjust the horizontal position of the deviation-correcting cylinder, and the device only needs one driving member to operate, which reduces the cost of use.

[0004] Current deviation correction devices require multi-stage linkage to operate, and generally the conveyor rollers are directly set to an adjustable state to achieve the deviation correction function, which increases the use burden of the conveyor rollers. In addition, the skewed movement of the conveyor rollers will also increase the probability of deviation. For this reason, a deviation adjustment mechanism is established. Utility Model Content

[0006] The top of the sliding plate is provided with a screw threadedly connected to the bottom of the sliding plate, and the output end of the second motor is detachably connected to the bottom of the sliding plate.

The establishment of an independent adjustment structure can ensure the simplicity of the conveying roller function, and there is no need for multi-stage linkage. The components can move independently and cooperate with each other, which increases the convenience of equipment use and the flexibility of adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom side wall of the skateboard 10 is fixedly connected to the top of the displacement plate, and the two moving blocks 8 have the same structure. The lower edge of the side of the vertical plate 11 away from the card plate 13 is fixedly connected with a mounting plate 12, and the mounting plate 12 is inserted with screws. The vertical plate 11 is detachably connected to the top side wall of the skateboard 10 through the mounting plate 12 and the screws, and the top side wall of the skateboard 10 is evenly provided with corresponding screw holes. A slide groove 7 is provided on the middle side wall of the top of the holding plate 6, and a main screw 16 is rotatably connected to the bottom of the slide groove 7. A slider 17 is inserted with a thread on the main screw 16, and the slider 17 is fixedly connected to the bottom side wall of the moving block 8 through the top, and one end side wall of the holding plate 6 is detachably connected to the second motor 18, and the output end of the second motor 18 is detachably connected to one end of the main screw 16.

[0016] As a preferred technical effect of the present scheme, the film is passed through the middle of the two pairs of card plates 13 and through the two conveying rollers 2, and the conveying rollers 2 are started to convey the film. The film can be limited by the established card plates 13, thereby reducing the probability of the film running off track. When the film runs off track, it is only necessary to start the No. 2 motor 18 to drive the main screw 16 to rotate, and drive the two card plates 13 to move through the threaded connection relationship, thereby driving the film to move and adjust it to the correct position, without the need for multi-stage linkage, thereby increasing the convenience of adjustment.

[0017] A movable groove 19 is opened in one of the clamping plates 13, and a spring 20 is evenly fixedly connected to the top side wall in the movable groove 19.

The spring 20 can alleviate the amplitude of the film during transportation and reduce the probability of vibration deviation. In order to accurately and quickly know the deviation of the film, two positioners 5 are set to position the edges on both sides of the film, so that they can cooperate with the No. 2 motor 18 to realize automatic and timely adjustment and correction functions.

[0019] Specifically, when the utility model is used, according to the width size of the film, the two No. 1 motors 15 are started to drive the corresponding secondary screws 14 to rotate, and the two slides 10 are driven to move through the threaded connection until the two card plates 13 are adjusted to the corresponding positions, ensuring that the two sides of the film are located in the middle of the corresponding two card plates 13, and the vertical plate 11 can be installed at different positions of the top side wall of the slide plate 10 as needed, thereby increasing the adjustment range and flexibility, and the film can be pressed by the established springs 20, pressing plates 21 and balls 22 to ensure that the film passes smoothly from the middle of the two card plates 13, and the two sides of the film are positioned and detected by the two positioners 5. When an offset occurs, the No. 2 motor 18 is started to drive the main screw 16 to rotate, and then the slider 17 is driven to move together with the two moving blocks 8 through the principle of threaded connection, thereby driving the film back to the correct position, ensuring the subsequent smooth production.
