Technical Field

[0001] This utility model relates to the field of cardboard production technology, specifically a folding mechanism for cardboard box production. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. Cardboard boxes commonly have three or five layers, while seven-layer boxes are less common. Each layer consists of linerboard, corrugated paper, core paper, and face paper. Linerboard and face paper can be made of kraft paper or kraft paper, while the core paper is made of corrugated paper. The colors and textures of various types of paper are different, and the paper produced by different manufacturers is also different.

[0003] In the production process of cardboard boxes, we need to crease the cardboard. Currently, creases are usually made manually using special tools or by manually feeding the cardboard into a crease machine. In other words, the existing crease mechanism is not highly automated and is time-consuming and labor-intensive. Utility Model Content

[0019] 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.

[0020] Please see Figures 1-5 This utility model provides a technical solution, including a base 1, an auxiliary crease mechanism 2 connected to the top of the base 1, a baffle 3 connected to the top of the base 1, a conveyor belt 4 rotatably connected between the baffles 3, a placement plate 5 connected to the top of the base 1 behind the auxiliary crease mechanism 2, a support column 6 connected to the top of the base 1, a support plate 7 connected to one side of the top of the support column 6, a guide sliding groove 8 opened on one side of the support plate 7, a crease mechanism 9 slidably arranged inside the guide sliding groove 8, an upright box 10 connected to the top of the base 1, and a enclosure 11 connected to the top of the upright box 10.

[0021] The auxiliary crease mechanism 2 is located above the baffle 3. Its function is to ensure that the material is not obstructed when it moves on the conveyor belt, which helps to maintain the smooth flow of the material and reduce downtime or blockage caused by interference of the mechanism.

[0022] The auxiliary crease mechanism 2 includes a gantry frame 21 connected to the top of the base 1, a crossbar 22 connected between the gantry frames 21, a first support frame 23 connected to one side of the gantry frame 21, a first motor 24 connected to the top of the first support frame 23, a bidirectional lead screw 25 connected to the output end of the first motor 24, two sets of sliders 26 threaded on the surface of the bidirectional lead screw 25, and the top of the sliders 26 slidingly disposed inside the crossbar 22. A crease roller 27 is rotatably disposed at the bottom of the sliders 26. Its function is to drive the bidirectional lead screw 25 to rotate through the first motor 24, and the two sets of sliders 26 will move along the thread direction of the bidirectional lead screw 25 to achieve precise position control. The mobility of the sliders 26 on the bidirectional lead screw 25 enables the auxiliary crease mechanism 2 to handle materials of different widths.

[0023] A protective plate is connected to one side of the top of the placement plate 5, and the top of the placement plate 5 is at the same horizontal height as the conveyor belt 4. Its function is to ensure that the material conveyed from the conveyor belt 4 can be smoothly transferred to the placement plate 5, avoiding material deviation or tipping problems caused by height difference.

[0024] The crease mechanism 9 includes a second support frame 91 connected to one side of the support plate 7. A second motor 92 is connected to the top of the second support frame 91. A reducer 93 is connected to one side of the output end of the second motor 92. An arc plate 94 is connected to the top of the second support frame 91. The output end of the reducer 93 passes through the arc plate 94 and one side of the inner wall of the guide sliding groove 8, and a transmission plate 95 is connected to its surface. A connecting shaft 96 is connected to one side of the transmission plate 95. A transmission shaft 97 is rotatably mounted on the surface of the connecting shaft 96. One end of the transmission shaft 97 is rotatably mounted with... The clamping plate 98 has a sliding plate 99 connected to its bottom end, and the sliding plate 99 is slidably disposed inside the guide sliding groove 8. The bottom end of the sliding plate 99 is connected to a connecting rod 100, and the bottom end of the connecting rod 100 is connected to a crease knife 101. Its function is to drive the reducer 93 through the second motor 92, and then through the transmission plate 95, connecting shaft 96 and transmission shaft 97, to finally control the movement of the clamping plate 98 and the sliding plate 99, allowing precise control of the position and force of the crease knife 101, so as to ensure that accurate and consistent creases are formed on the material.

[0025] The top of the upright box 10 has a crease groove 111 corresponding to the crease knife 101. The function of the crease groove 111 is to enable the crease knife 101 to be accurately aligned with the predetermined position on the material during operation, so as to ensure the accuracy of the crease. The presence of the crease groove 111 can guide the crease knife 101 to form a more uniform and consistent crease on the material.

[0026] The upright box 10 is located directly below the crease mechanism 9. Its function is that the design of the upright box 10 being located directly below the crease mechanism 9 allows the material to be directly taken from the conveyor belt into the upright box 10 and then immediately creased.

[0027] Working principle: Cardboard box materials are placed on conveyor belt 4, which rotates between baffles 3, transporting the materials from one end to the other. During this process, the materials move smoothly, preparing for subsequent crease treatment. When the materials reach below the auxiliary crease mechanism 2, the first motor 24 starts, driving the bidirectional lead screw 25 to rotate. Since the slider 26 is threaded onto the bidirectional lead screw 25 and its top end slides inside the crossbar 22, the slider 26 moves along the axial direction of the bidirectional lead screw 25, determining the width of the crease. After the auxiliary crease treatment, the materials continue to move along the conveyor belt 4 and are finally placed on the placement plate 5. The placement plate 5 and the conveyor belt 4 are at the same horizontal level, ensuring a smooth transition of materials. At the same time, the presence of the guard plate prevents the materials from slipping during placement. Then, the operator puts the materials on the placement plate 5 into the upright box 10. The second motor 92 starts and, after being decelerated by the reducer 93, drives the transmission plate 95 to move along the arc plate 94 and the guide sliding groove 8. This movement causes the linkage of the connecting shaft 96, the transmission shaft 97, the clamping plate 98 and the sliding plate 99, which ultimately allows the crease knife 101 to perform precise crease treatment on the materials. After the crease treatment is completed, the materials can be taken out from the upright box 10 for subsequent processing or packaging.
