Description

Technical Field

[0001] The utility model relates to the technical field of color box production equipment, in particular to a paper pushing mechanism which is convenient for fixing paperboard. Background Art

[0002] Color boxes are the most widely used packaging products. They come in various specifications and models and are assembled from colored cardboard. During the processing of cartons, the cardboard needs to be cut to meet the production of cartons of different shapes. When cutting the cardboard, the neatly stacked cardboard generally needs to be pushed to the bottom of the cutting device for cutting through a paper pushing mechanism.

[0003] According to a disclosed paper pushing mechanism for color box processing (publication number: CN212603663U), in the above application, a tooth block is arranged on the bottom surface of the slide plate, and a transmission belt is arranged on the bottom surface of the groove. The movement of the transmission belt will drive the slide plate to move, and the box plate can be transmitted to the bottom of the cutting device. After the cutting is completed, the slide plate can be removed together with the box plate, and the new slide plate together with the box plate can be directly placed on the workbench.

[0004] However, in actual use of the above-mentioned device, when the cardboard is placed on the slide and moves with it, the cardboard is limited only by the pressing device on the top. At this time, the cardboard still has a certain degree of freedom in the horizontal direction and can move. When the transmission speed of the conveyor belt is fast, the cardboard will have a large inertia. As the conveyor belt stops quickly, part of the cardboard will move due to inertia, resulting in deviation, making it impossible to align the entire cardboard pile, affecting the subsequent cutting. In view of this, we propose a paper pushing mechanism that is convenient for fixing the cardboard. Utility Model Content

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a paper pushing mechanism that is convenient for fixing cardboard, comprising a processing table 1, a conveyor belt 2 is arranged on the upper surface of the processing table 1, a cutting machine 3 is arranged at the right end of the processing table 1, a lifting plate 4 is fixedly installed on the upper surface of the conveyor belt 2, when the conveyor belt 2 is started, the lifting plate 4 can be driven to perform linear motion in the left and right directions, when the conveyor belt 2 drives the cardboard placed above the lifting plate 4 to move to the bottom of the cutting machine 3, the cutting machine 3 can cut the edges and corners of the cardboard, and a fixing component is arranged above the lifting plate 4.

[0024] The fixing assembly includes: a fixing plate 501, a groove 503 and an L-shaped placement frame 507. The fixing plate 501 is fixedly installed with the upper surface of the lifting plate 4. The front and rear ends of the upper surface of the fixing plate 501 are provided with guide plates 502 in a mirror structure. The upper end of the guide plate 502 is arranged in a structure inclined toward the outside of the fixing plate 501. The distance between the two guide plates 502 is the same as the width of the cardboard. When the cardboard is placed from above the guide plate 502 into between the two guide plates 502 for placement and limiting, the guide plate 502 can guide the movement of the cardboard, so that the cardboard can be placed downward along the inclined surface of the guide plate 502, which is convenient for the staff to perform the placement operation.

[0025] An air pump 506 is fixedly installed at the right end of the fixing plate 501, a groove 503 is opened at the center of the upper surface of the fixing plate 501, a limit plate 504 is fixedly installed at the center of the inner bottom surface of the groove 503, an air bag 505 is fixedly installed at the right end of the inner bottom surface of the groove 503, the left output end of the air pump 506 is fixedly connected to the right side surface of the air bag 505, and the air pump 506 can be started to inflate or evacuate the inside of the air bag 505. When the air bag 505 is inflated, it will expand upwards. The L-shaped placement frame 507 is hinged on the groove At the inner left end of the groove 503, the bottom surface of the L-shaped placement frame 507 is in contact with the upper surfaces of the limiting plate 504 and the airbag 505. The inner bottom surface of the L-shaped placement frame 507 and the upper surface of the fixing plate 501 are located in the same horizontal plane. The limiting plate 504 can limit the L-shaped placement frame 507 so that the L-shaped placement frame 507 can remain horizontally placed without external interference. When the airbag 505 is inflated, it will push the L-shaped placement frame 507 upward, so that the L-shaped placement frame 507 flips upward around the hinge.

[0026] After placing the cardboard inside the L-shaped placement rack 507, start the air pump 506 to supply air to the airbag 505, so that the airbag 505 expands and pushes the L-shaped placement rack 507 upward, causing the L-shaped placement rack 507 to rotate slightly upward. At this time, the cardboard placed on the L-shaped placement rack 507 will also tilt to the lower left, thereby preventing part of the cardboard from moving to the right due to inertia when the conveyor belt 2 is started to drive the cardboard to move to the right, resulting in the entire cardboard pile being unable to be stably aligned, affecting the subsequent cutting effect.

[0027] An extension plate 508 is fixedly installed on the upper surface of the L-shaped placement rack 507, and an electric telescopic rod 509 is fixedly installed on the bottom surface of the extension plate 508. A pressing plate 510 is fixedly installed on the bottom end of the electric telescopic rod 509. When the cardboard is placed into the L-shaped placement rack 507, the electric telescopic rod 509 can be started to drive the pressing plate 510 to move downward to fix the cardboard, so that the cardboard remains stable during the movement, further avoiding deviation and falling.

[0028] A moving groove 601 is provided on the left surface of the fixed plate 501, and an elastic member 602 is fixedly installed on the right inner wall surface of the moving groove 601, and a pushing plate 603 is fixedly installed on the left end of the elastic member 602. The size of the bottom end of the pushing plate 603 is adapted to the size of the moving groove 601. After the cardboard is pushed and cut, the staff can move the pushing plate 603 to the right to push the cardboard to the right, so that the right end of the cardboard is exposed from the fixed plate 501, which is convenient for the staff to take the cardboard. In the process of moving the pushing plate 603, the pushing plate 603 will squeeze the elastic member 602, so that the elastic member 602 is compressed to generate elastic potential energy. After the cardboard is pushed, when the staff releases the pushing plate 603, the pushing plate 603 will move and reset under the action of the elastic potential energy of the elastic member 602, which is convenient for the next use.

[0029] In the present invention, when in use, the cardboard is passed through the right end of the extension plate 508, and after passing through the guide limit of the guide plate 502, it enters the interior of the L-shaped placement rack 507, and then the air pump 506 is started to supply air to the inside of the airbag 505, so that the airbag 505 expands and pushes the right end of the L-shaped placement rack 507 upward, so that the cardboard placed in the L-shaped placement rack 507 is tilted, thereby avoiding that when the conveyor belt 2 is started to drive the cardboard to move to the right, part of the cardboard moves to the right under the action of inertia, resulting in the cardboard pile being unable to align, affecting the subsequent cutting effect. After placement is completed, the electric telescopic rod 509 can be started to drive the pressing plate 510 to move downward to fix the cardboard and limit it, so that the cardboard remains stable during the movement. After cutting is completed, the electric telescopic rod 509 can be started to drive the pressing plate 510 to move upward to release the limit on the cardboard, and then the cardboard is pushed to the right by moving the push plate 603, which is convenient for the staff to take the cardboard.

[0030] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
