Description

Technical Field

[0001] The utility model relates to the technical field of carton processing, in particular to a bending mechanism for carton processing. Background Art

[0002] Cartons are the most widely used packaging products. Depending on the materials used, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Commonly used cartons are three-layer and five-layer, and seven-layer are less used. Each layer is divided into lining paper, corrugated paper, core paper and face paper. The color and feel of each paper are different, and the papers produced by different manufacturers are also different.

[0003] When processing cartons, the cardboard needs to be bent by a bending mechanism for subsequent forming. However, the existing bending mechanism has a relatively simple limiting method for the bent cardboard, and generally only limits the position of the cardboard in one direction, resulting in poor fixing effect. It is easy to shift during bending, affecting the bending processing operation. When multiple parts of the cardboard need to be bent, the position of the cardboard needs to be manually adjusted, which is troublesome and affects work efficiency. For this reason, we propose a bending mechanism for carton processing. Utility Model Content

[0030] See also Figure 1-Figure 5 A bending mechanism for carton processing comprises a bottom plate 1 and a paperboard 14, a truncated table 13 is fixedly mounted on the upper end surface of the bottom plate 1, side plates 2 are fixedly connected to both side walls of the bottom plate 1, a top plate 3 is fixedly mounted on the outer side wall of one group of side plates 2 near the upper end, a limiting mechanism 23 is arranged on the bottom surface of the top plate 3, and an auxiliary mechanism 24 is arranged between the outer walls of the two groups of side plates 2; the limiting mechanism 23 comprises an electric telescopic rod 4 and a circular frame 6, the electric telescopic rod 4 is mounted on the bottom surface of the top plate 3, the circular frame 6 is movably arranged above the paperboard 14, the electric telescopic rod 4 is fixedly connected to a U-shaped connecting plate 5 at one end away from the top plate 3, and a U-shaped fixing plate 7 is fixedly connected to the outer wall of the circular frame 6 near the middle position.

[0031] Among them, the electric telescopic rod 4 extends, driving the U-shaped connecting plate 5 to move downward, which can drive the circular frame 6 connected by the U-shaped fixing plate 7 in the limiting mechanism 23 to move downward to a position where its bottom surface is close to the upper end surface of the paperboard 14, thereby vertically suppressing the position of the paperboard 14.

[0032] The U-shaped fixing plate 7 is fixedly connected to the U-shaped connecting plate 5, and a sliding rod 10 is fixedly installed between the two inner side walls of the circular frame 6. Slide blocks 11 are sleeved on the outside of the sliding rod 10 near the two ends. The bottom ends of the two groups of slide blocks 11 are fixedly connected to the clamping plates 12, and the outer side walls of the two groups of slide blocks 11 are fixedly connected to the racks 9. The top end of the U-shaped fixing plate 7 is rotatably connected to the connecting shaft 8, and the bottom end of the connecting shaft 8 is fixedly connected to the gear 25, and the gear 25 and the two groups of racks 9 are meshed with each other. A motor 1 is installed on the upper end surface of the U-shaped fixing plate 7, and the output end of the motor 1 is connected to one end of the connecting shaft 8. The connecting shaft 8 is driven by the motor 1 to rotate clockwise, which drives the two groups of racks 9 to transmit, so that the two groups of slide blocks 11 move along the sliding rod 10 at the same time, drive the two groups of clamping plates 12 to move and approach each other, and the cardboard 14 can be clamped and fixed in the horizontal position.

[0033] When in use, the cardboard 14 to be bent is placed on the upper end surface of the truncated table 13 arranged on the bottom plate 1, and the middle part of the cardboard 14 is opposite to the truncated table 13 and is placed vertically on the bottom plate 1. At this time, the U-shaped connecting plate 5 can be driven downward by the electric telescopic rod 14 installed on the bottom surface of the top plate 3, thereby driving the circular frame 6 connected by the U-shaped fixing plate 7 in the limiting mechanism 23 to move downward to a position where its bottom surface is close to the upper end surface of the cardboard 14, and the position of the cardboard 14 is vertically pressed to preliminarily limit its position on the truncated table 13, and then the connecting shaft 8 is driven to rotate clockwise by the motor 1 installed on the U-shaped fixing plate 7. Rotation can drive the two sets of racks 9 to transmit in opposite directions, thereby driving the two sets of sliders 11 to move along the slide rod 10 at the same time and approach each other, driving the two sets of clamping plates 12 to move and also approach each other until the outer walls of the two sets of clamping plates 12 are respectively close to the two side walls of the paperboard 14, so that the paperboard 14 can be clamped and fixed in the horizontal position, and its position can be further fixed. Through the above operation, the paperboard 14 to be bent can be fixed in the vertical and horizontal positions, effectively improving the fixing effect of the paperboard 14, and preventing it from moving and affecting the subsequent bending operation.

[0034] See also Figure 1 , Figure 4 and Figure 5 The auxiliary mechanism 24 includes four groups of transverse grooves 27, and every two groups of transverse grooves 27 are respectively opened through the outer side walls of the two groups of side plates 2 near the bottom. The four groups of transverse grooves 27 are rotatably connected with threaded rods 16, and the four groups of threaded rods 16 are located inside the transverse grooves 27 and are sleeved with movable blocks 17.

[0035] One end of the four groups of movable blocks 17 are fixedly connected to a mounting shell 18, and a connecting block 19 is inserted inside the four groups of mounting shells 18. An electric telescopic rod 20 is installed at the top of the mounting shell 18, and one end of the electric telescopic rod 20 is fixedly connected to the connecting block 19. A U-shaped bearing plate 21 is fixedly connected between the outer walls of the two groups of mounting shells 18 and below the cardboard 14. A pressure strip 22 is fixedly connected between the outer walls of the two groups of connecting blocks 19 and above the cardboard 14. The pressure strip 22 is matched with the U-shaped bearing plate 21. When the cardboard 14 to be bent is placed on the truncated table 13, the cardboard 14 is located on the upper end surface of the U-shaped bearing plate 21, and the pressure strip 22 is located above the cardboard 14.

[0036] Motor 2 is installed on both outer side walls of the two groups of side plates 2, and the output end of motor 2 is connected to one end of the threaded rod 16. The upper and lower inner side walls of the transverse groove 27 are provided with limited long grooves 15. Limit blocks 26 are inserted inside the two groups of limited long grooves 15, and the two groups of limit blocks 26 are fixedly connected to the movable block 17 at one end away from the limit long grooves 15. A circular hole is penetrated through the outer side wall of the movable block 17, and a thread matching the threaded rod 16 is provided on the inner side wall of the circular hole. When motor 2 rotates forward, the two groups of movable blocks 17 can be driven to move along the two groups of threaded rods 16 respectively and approach each other. Similarly, when motor 2 is reversed, the two groups of movable blocks 17 can be moved away from each other. When the movable block 17 moves, the two groups of limit blocks 26 connected thereto follow it and move along the two groups of limit long grooves 15 respectively, so as to limit the moving position of the movable block 17 and prevent it from rotating on the threaded rod 16.

[0037] Specifically, after the position of the cardboard 14 to be bent is fixed, the four sets of threaded rods 16 can be driven to rotate by the four sets of motors 2, respectively, thereby driving the movable block 17 in the auxiliary mechanism 24 to move along the transverse groove 27, driving the mounting shell 18 to move, thereby driving the U-shaped carrier plate 21 and the pressure strip 22 installed thereon to move along the cardboard 14, and the U-shaped carrier plate 21 and the pressure strip 22 can be moved to the bending part of the cardboard 14. After the movement is completed, the connecting block 19 can be driven to move downward by the electric telescopic rod 20, thereby driving the pressure strip 22 to move downward toward the U-shaped carrier plate 21. The cardboard 14 is moved internally to bend the cardboard 14. Similarly, another set of pressure strips 22 can be used to cooperate with the U-shaped supporting plate 21 to bend the other end of the cardboard 14. Similarly, when it is necessary to bend other parts of the cardboard 14, the positions of the pressure strips 22 and the U-shaped supporting plate 21 on the cardboard 14 can be adjusted by the threaded rod 16 and the movable block 17 to perform bending processing on other positions on the cardboard 14. Through the above operations, there is no need to frequently adjust the position of the cardboard 14 manually, and the bending operation of multiple parts of the cardboard 14 to be bent can be completed, which effectively improves the work efficiency.
