Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cardboard box production and processing technology, specifically a folding device for cardboard box production and processing. Background Technology
[0002] Cardboard box manufacturing refers to the process of using raw materials through a series of processes to produce cardboard boxes for packaging, transporting, and storing goods. During manufacturing, cardboard boxes require crease treatment; different creases are pressed onto the surface of the box according to different requirements, facilitating subsequent folding. However, the crease rollers on existing cardboard box manufacturing crease devices are generally positioned in a fixed manner, resulting in uniform crease depths. This makes it difficult to adjust the crease depth according to actual needs, limiting their application. Utility Model Content
[0003] To overcome the above-mentioned defects, this utility model provides a crease device for carton production and processing, which solves the problem that the crease rollers in existing crease devices for carton production and processing are generally positioned in a fixed manner, resulting in equal crease depths, making it difficult to adjust the crease depth according to actual needs, and thus limiting its application range.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a crease device for carton production and processing, comprising a base plate, two supports fixedly connected to the top of the base plate, a conveyor belt assembly disposed between the two supports, a U-shaped frame fixedly connected to the top of the two supports, a motor fixedly connected to the U-shaped frame, a bidirectional lead screw fixedly connected to the output end of the motor, and the bidirectional lead screw being rotatably connected to the U-shaped frame via bearings;
[0005] A fixed rod is fixedly connected to the U-shaped frame. Two movable rods are threadedly connected to the bidirectional lead screw. The movable rods are slidably connected to the fixed rod. A connecting rod is hinged to the bottom of the movable rod. There are two connecting rods. A movable plate is hinged to the bottom of the two connecting rods. A U-shaped plate is fixedly connected to the bottom of the movable plate. A crease roller is rotatably connected to the U-shaped plate.
[0006] As a further embodiment of this utility model: a support plate is fixedly connected to the U-shaped frame, and the support plate is located at the bottom of the motor.
[0007] As a further embodiment of this utility model: two limiting grooves are provided on the U-shaped frame, and sliders are fixedly connected to both sides of the movable plate, and the sliders are slidably connected inside the limiting grooves.
[0008] As a further embodiment of this utility model: four self-locking casters are fixedly connected to the bottom of the base plate, and the four self-locking casters are evenly distributed on the bottom of the base plate.
[0009] As a further embodiment of this utility model: a handle is fixedly connected to the top of the base plate, and the handle has an arc surface design.
[0010] As a further embodiment of this utility model: the crease roller is located on top of the conveyor belt assembly, and the conveyor belt assembly is located on top of the base plate.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] 1. This crease-reducing device for cardboard box production comprises a crease roller, a moving plate, a connecting rod, a bidirectional lead screw, and a motor. In use, cardboard is placed on a conveyor belt assembly for transport. When the cardboard reaches below the crease roller, its height needs adjustment. At this point, the motor is started, driving the bidirectional lead screw to rotate. Because the threads on both sides of the bidirectional lead screw are in opposite directions, its rotation causes the two moving rods to move closer or further apart. When the two moving rods are closer, they push the moving plate downwards via the connecting rod. When the two moving rods are further apart, they pull the moving plate upwards via the connecting rod. The moving plate then moves the U-shaped plate and the crease roller, allowing the height of the crease roller to be adjusted according to actual needs. By adjusting the height of the crease roller, the crease depth can be adjusted as needed, expanding its application range.
[0013] 2. This crease-reducing device for cardboard box production and processing features a handle, a base plate, and self-locking casters. When the device needs to be moved, the handle is gripped to push the base plate, causing the casters to roll on the ground. When the base plate reaches the designated position, the casters lock, securing the base plate and completing the transfer. The self-locking casters transform the sliding friction between the base plate and the ground into rolling friction, reducing friction and making it easier for personnel to push the base plate, thus facilitating the transfer of the device.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a folding device for carton production and processing, including a base plate 1, two supports 2 fixedly connected to the top of the base plate 1, a conveyor belt assembly 3 arranged between the two supports 2, a U-shaped frame 4 fixedly connected to the top of the two supports 2, and a support plate 6 fixedly connected to the U-shaped frame 4. Because of the support plate 6, the support plate 6 can support the motor 5, thereby improving the stability of the motor 5. The support plate 6 is located at the bottom of the motor 5.
[0020] A motor 5 is fixedly connected to the U-shaped frame 4. A bidirectional lead screw 8 is fixedly connected to the output end of the motor 5. The bidirectional lead screw 8 is rotatably connected to the U-shaped frame 4 through bearings. A fixed rod 7 is fixedly connected to the U-shaped frame 4. Because of the fixed rod 7, when the moving rod 11 moves, the fixed rod 7 can limit the movement of the moving rod 11, thereby improving the stability of the movement of the moving rod 11. Two moving rods 11 are threadedly connected to the bidirectional lead screw 8. Two limiting grooves 17 are opened on the U-shaped frame 4. Because of the limiting grooves 17, when the moving plate 13 moves, the slider 14 will slide inside the limiting grooves 17. The limiting grooves 17 limit the movement of the slider 14 and the moving plate 13, thereby improving the stability of the movement of the moving plate 13. Slider 14s are fixedly connected to both sides of the moving plate 13, and the slider 14s are slidably connected inside the limiting grooves 17.
[0021] The movable rod 11 is slidably connected to the fixed rod 7. The bottom of the movable rod 11 is hinged to a connecting rod 12. There are two connecting rods 12. The bottom ends of the two connecting rods 12 are hinged to a movable plate 13. The bottom of the movable plate 13 is fixedly connected to a U-shaped plate 15. The bottom of the base plate 1 is fixedly connected to four self-locking casters 9. The self-locking casters 9 change the sliding friction between the base plate 1 and the ground into rolling friction, thereby reducing friction and making it easier for personnel to push the base plate 1, thus facilitating the transfer of the device. The four self-locking casters 9 are evenly distributed on the bottom of the base plate 1.
[0022] A crease roller 16 is rotatably connected to the U-shaped plate 15. The crease roller 16 is located on the top of the conveyor belt assembly 3, which is located on the top of the base plate 1. A handle 10 is fixedly connected to the top of the base plate 1. Because of the handle 10, a gripping point is provided, making it easy for personnel to hold the handle 10 and push the base plate 1, thus improving the ease of operation. The handle 10 has an arc surface design.
[0023] The working principle of this utility model is as follows:
[0024] In use, the cardboard is placed on the conveyor belt assembly 3 for conveying. When the cardboard is conveyed to the bottom of the crease roller 16, the height of the crease roller 16 needs to be adjusted. At this time, the motor 5 is started to drive the bidirectional lead screw 8 to rotate. Since the threads on both sides of the bidirectional lead screw 8 are opposite, when the bidirectional lead screw 8 rotates, the two moving rods 11 can move closer or further away from each other. When the two moving rods 11 move closer to each other, the moving rods 11 will push the moving plate 13 down through the connecting rod 12. When the two moving rods 11 move further away from each other, the moving rods 11 will pull the moving plate 13 up through the connecting rod 12. The moving plate 13 drives the U-shaped plate 15 and the crease roller 16 to move, so that the height of the crease roller 16 can be adjusted according to actual needs. By adjusting the height of the crease roller 16, the depth of the crease can be adjusted, and the pressure of the crease roller 16 on the cardboard can be used to form a crease on the cardboard.
[0025] When the device needs to be moved, hold the handle 10 and push the base plate 1. At this time, the self-locking caster 9 will roll on the ground. When the base plate 1 is pushed to the designated position, the self-locking caster 9 will lock and fix the base plate 1, thus completing the transfer of the device.
