Description

Technical Field

[0001] This utility model relates to the field of cardboard processing technology, specifically a cardboard edge flattening and trimming device. Background Technology

[0002] When assembling cardboard boxes, the edges of the cardboard need to be flattened. This flattening process allows the cardboard box to withstand greater forces from one direction, which helps improve the structural strength and durability of the box.

[0003] Currently, when flattening the edges of cardboard boxes, workers determine the edges and place them under the flattening device to wait for the flattening. However, some cardboard boxes have relatively long edges, so workers need to manually move them after each flattening, which is dangerous and labor-intensive. In addition, the current flattening process is a one-time compression, resulting in a very poor overall flattening effect and failing to effectively flatten the edges of the cardboard boxes.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-4 As shown, this utility model provides a carton edge flattening and trimming device, including a base plate 1, a placement plate 11 slidably mounted on the upper surface of the base plate 1, a bracket 12 in an inverted L-shape fixed at one end of the upper surface of the base plate 1, a mounting plate 13 fixed at the top of the bracket 12, two vertically arranged movable plates 14 arranged inside the mounting plate 13, a rectangular groove 15 penetrating through the middle end of the movable plate 14, an arc-shaped groove 16 formed at the diagonal of the rectangular groove 15, and a Y-shaped rotating plate 17 at the middle end of the rectangular groove 15, the top of the rotating plate 17 being able to engage with the rectangular groove. 15 The side walls abut each other. The upper and lower ends of the movable plate 14 are fixed with top rods 19. The top rod 19 located below is fixed with a U-shaped top plate 2. The two ends of the top plate 2 movably pass through the top of the bracket 12 and are jointly fixed with a pressure plate 21. The two sides of the placement plate 11 are fixed with sliding plates 3. The sliding plates 3 are slidably inserted into the side wall of the base plate 1. The sliding plate 3 near the bracket 12 passes through the base plate 1 and the lower surface is fixed with a slider 31. The side wall of the base plate 1 near the slider 31 is equipped with a rotating screw 32. The bottom of the slider 31 is threaded on the screw 32.

[0018] The top plate 2 is fitted with a return spring 22 at both ends above the bracket 12. The return spring 22 can assist the top plate 2 to move upward after it moves downward, waiting for it to be pressed down again.

[0019] A horizontally arranged rotating shaft 18 is fixedly provided at the middle end of the rotating plate 17. Both ends of the rotating shaft 18 rotate on the mounting plate 13. A drive motor 23 is fixedly installed at one end of the mounting plate 13. The output end of the drive motor 23 is coaxially fixed on the rotating shaft 18. The drive motor 23 can directly drive the rotating shaft 18 to rotate the rotating plate 17, which is convenient for the staff to operate.

[0020] The top rod 19 located on the movable plate 14 is installed through the movable plate 14, which ensures that the movable plate 14 can move stably up and down in the vertical direction.

[0021] A support block 33 is fixed to the side wall of the base plate 1 near the end of the lead screw 32. One end of the lead screw 32 is rotatably mounted on the support block 33. A connecting shaft 34 is rotatably mounted on the side wall of the support block 33. A half-face gear 35 is fixed on the connecting shaft 34. A full gear 36 that meshes with the half-face gear 35 is fixed to the end of the lead screw 32 near the connecting shaft 34. When the half-face gear 35 drives the full gear 36 to rotate, it can intermittently drive the lead screw 32 to rotate. This allows the lead screw 32 to drive the slider 31 and the slide plate 3 to move the placement plate 11 a certain distance when the pressure plate 21 moves upward. This allows the carton board placed on the placement plate 11 to automatically pass under the pressure plate 21 and be flattened under the action of the placement plate 11. The rotating shaft 18 is connected to the connecting shaft 34 by a belt 37. Specifically, the rotating shaft 18 and the connecting shaft 34 are connected by a pulley and the belt 37. The two are linked, which reduces the installation of electrical equipment and increases the overall size of the device.

[0022] Two symmetrically arranged long rods 4 are movably inserted on the side of the placement plate 11 away from the belt 37. A vertical plate 41 is fixed at the end of the two long rods 4 away from the placement plate 11. The long rods 4 and the vertical plate 41 can be arranged along the length of the cardboard boxes placed on the placement plate 11, so as to better adapt to cardboard boxes of different specifications.

[0023] Working principle: During use, the operator can place the edge of the cardboard box to be flattened on the placement plate 11 and abut against the bracket 12. At this time, the pressing plate 21 is at its highest point, and the half-gear 35 and the full gear 36 are completely disengaged. Figure 1 and 4As shown, starting the drive motor 23 can drive the rotating shaft 18 to rotate clockwise. At this time, the rotating shaft 18 drives the rotating plate 17 to rotate clockwise. When the rotating plate 17 rotates, one end of the rotating plate 17 will abut against the bottom of the rectangular groove 15. At this time, the rotating plate 17 will push the movable plate 14 to move downward, so that the pressing plate 21 flattens the cardboard on the placement plate 11. As the end of the rotating plate 17 rotates into the arc groove 16, the half-face gear 35 will mesh with the full gear 36. As the rotating plate 17 continues to rotate, the other end of the rotating plate 17 will abut against the side wall above the rectangular groove 15. At this time, the rotating plate 17 will push the movable plate 14 upward. At the same time, the half-face gear 35 will drive the full gear 36 to move upward. When the lead screw 32 rotates, during the upward movement of the pressure plate 21, the rotating lead screw 32 drives the slide plate 3 and the slider 31 to move the placement plate 11 and the upper cardboard board by a certain displacement. After the above operation, when the rotating shaft 18 rotates, it can push the movable plate 14 to move up and down repeatedly. This allows the top rod 19 at the bottom of the movable plate 14 to push the top plate 2 to drive the pressure plate 21 to repeatedly flatten the edge of the lower cardboard board, making the cardboard box flat and improving the flattening efficiency of the cardboard box. At the same time, during the upward movement of the pressure plate 21, the placement plate 11 can intermittently move the cardboard board, eliminating the need for manual movement by the staff, greatly improving the operating efficiency, reducing the workload of the staff, and providing safety for the staff.

[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
