Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, and in particular to a flattening device for cardboard box processing. Background Technology

[0002] Cardboard boxes are a common type of packaging material, used for products such as food, electronics, and cosmetics. They are used in the production and sales process to enhance the product's appearance. During the production process, cardboard boxes need to be flattened, which requires the use of flattening devices.

[0003] A search revealed a cardboard box flattening device (publication number: CN218315523U) on the Chinese Patent Network. The device includes a housing with openings on both sides along its length. Cardboard boxes are placed on the bottom wall of the housing. Several straight toothed racks are fixedly connected to the top wall of the housing. Two vertical plates are installed inside the housing, and a limiting component is provided between the vertical plates and the inner wall of the housing. Through the cooperation of a motor, flattening rollers, gears, vertical plates, and separators, the device immediately flattens the next cardboard box after one has been flattened. Operators can replace the flattened boxes, allowing the device to continuously perform flattening operations, thereby improving the efficiency of cardboard box flattening.

[0004] While the application has some practical effects in actual use, it still has certain drawbacks. For example, the application requires two workers to actively step on foot pedals to limit and fix the cardboard box. After flattening, the cardboard box is manually removed for unloading. This flattening method not only increases labor costs, but also makes manual unloading slow, thus directly affecting the processing efficiency of the cardboard box. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1, referring to Figure 1-4A cardboard box flattening device includes a processing table 1, an industrial control host 2 fixedly connected to the left side of the processing table 1, a strip groove formed on the upper surface of the processing table 1, a first conveyor belt 3 and a second conveyor belt 4 arranged on the inner wall of the strip groove, a flattening assembly fixedly connected to the upper surface of the processing table 1, the flattening assembly including a support frame 5, a hydraulic cylinder 6 fixedly connected to the upper surface of the support frame 5, a pressing plate 7 fixedly connected to the output end of the hydraulic cylinder 6, sliding grooves formed on both the left and right sides of the support frame 5, and two first electric push rods 8 and 90mm rods fixedly connected to the front and back of the support frame 5 at positions corresponding to the sliding grooves, respectively. The second electric push rod 9 has two sliders 10 slidably connected to the inner wall of the slide groove. Each pair of left and right corresponding sliders 10 form a group. Each group of sliders 10 has a strip frame 11 fixedly connected to the opposite side. Each group of strip frames 11 has a moving groove on the opposite side. The upper surface of the strip frame 11 is fixedly connected to the first telescopic cylinder 12. The output end of the first telescopic cylinder 12 is fixedly connected to the movable block 13. The side of the movable block 13 is fixedly connected to the locking plate 14. The lower surface of the processing table 1 is fixedly connected to the second telescopic cylinder 15. The output end of the second telescopic cylinder 15 is fixedly connected to the support base frame 16.

[0024] The positions of the first conveyor belt 3 and the second conveyor belt 4 correspond to the positions of the support base 16. The industrial control host 2 is electrically connected to the hydraulic cylinder 6, the first electric push rod 8, the second electric push rod 9, the first telescopic cylinder 12, and the second telescopic cylinder 15, respectively. The output ends of the two first electric push rods 8 and the second electric push rod 9 are fixedly connected to two sets of sliders 10, respectively. The front and back of the support frame 5 are provided with round holes that are compatible with the output shafts of the first electric push rods 8 and the second electric push rods 9. The movable block 13 slides against the inner wall of the moving groove. The first telescopic cylinder 12 is connected, and the output end of the first telescopic cylinder 12 extends into the interior of the slide groove and is fixedly connected to the upper surface of the movable block 13. The strip frame 11 is slidably connected to the inner wall of the support frame 5, and the thickness of the strip frame 11 is less than the distance between the inner wall of the support frame 5 and the inner wall of the strip groove. The upper surface of the support base frame 16 is provided with a pressure groove, and the support base frame 16 is located between the first conveyor belt 3 and the second conveyor belt 4. The size of the pressure plate 7 is the same as the size of the inner wall of the pressure groove on the upper surface of the support base frame 16, and the position of the pressure plate 7 corresponds to the position of the pressure groove.

[0025] The first conveyor belt 3 can automatically transport the carton to the top of the support base 16. At this time, the four first telescopic cylinders 12 drive the locking plate 14 to descend to the bottom of the carton. The two first electric push rods 8, the second electric push rod 9 and the two sets of sliders 10 drive the two sets of strip frames 11 to move closer to each other. At this time, the four locking plates 14 can press the carton firmly on the support base 16 to ensure the stability of the carton during the flattening process.

[0026] Then, the hydraulic cylinder 6 drives the pressing plate 7 to descend. The pressing plate 7 can flatten the carton on the support base 16. After flattening, the two first telescopic cylinders 12 at the front end drive the two locking plates 14 at the front end to rise. At the same time, the two second electric push rods 9 drive the two strip frames 11 at the front end to move forward through the slider 10, so that the front of the support base 16 is unobstructed. The second telescopic cylinder 15 can drive the support base 16 to rise, so that the height of the pressing groove is higher than the height of the second conveyor belt 4. At this time, the two first telescopic cylinders 12 at the rear end drive the locking plates 14 to rise to the height of the pressing groove. At the same time, the two first electric push rods 8 drive the two strip frames 11 at the rear end to move forward through the slider 10, so that the two locking plates 14 at the rear end can automatically push the flattened carton in the pressing groove onto the second conveyor belt 4, completing the automated unloading operation.

[0027] Working principle: First, the carton is conveyed by the first conveyor belt 3. When the carton moves to the front end of the first conveyor belt 3, it first contacts the upper surface of the support base 16. Under the influence of the conveying force of the first conveyor belt 3, it eventually moves to a position above the support base 16. At this time, the four first telescopic cylinders 12 are activated, which drive the four locking plates 14 to descend through the four movable blocks 13. At the same time, the two first electric push rods 8 and the two second electric push rods 9 are activated, which drive the two sets of strip frames 11 to move closer to each other through the slider 10. At this time, the two sets of locking plates 14 can press the front and rear surfaces of the carton together, making the carton more stable on the support base 16. At the same time, the hydraulic cylinder 6 is activated and drives the pressing plate 7 to descend. The lowering and pressing plate 7 can cooperate with the support base 16 to automatically flatten the carton on the support base 16. After flattening, the two front first telescopic cylinders 12 and the second electric push rod 9 first drive the locking plate 14 back to its original position, so that there is no obstruction in front of the support base 16. Then, the second telescopic cylinder 15 drives the support base 16 to rise until it is higher than the height of the second conveyor belt 4. At the same time, the first electric push rod 8 and the first telescopic cylinder 12 cooperate to push the flattened carton on the support base 16 forward, so that the carton can be automatically pushed onto the second conveyor belt 4 to complete the automated unloading operation without the need for manual handling by the staff, which greatly improves the flattening efficiency of the carton.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
