Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing, and in particular to a cardboard box flattening device. 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 different types of paper are different, and the paper produced by different manufacturers also varies in color and texture.

[0003] Currently, most existing carton flattening devices use cylinders or push rod motors to push the pressure plate downwards, quickly flattening the carton in one go. However, the pressure plate in the existing technology does not have a buffering function. If the pressure of the pressure plate is too large, it can easily cause serious deformation or even damage to the carton, and the quality of the flattened carton cannot be guaranteed. Therefore, a buffering mechanism is added to the carton flattening device. For example, in the patent with patent number "202420521183.0" and patent name "A Carton Flattening Device", a spring and hydraulic rod are set between the pressure plate and the fixed plate to achieve a buffering effect. However, the inventor believes that this traditional vertical buffer component is mainly for buffering forces in the vertical direction. When the carton is subjected to lateral or oblique forces, the buffering effect of the vertical spring will be greatly reduced. For example, when the carton is subjected to a side collision or when there is a lateral reaction force due to uneven distribution of internal items, the vertical spring, because its main force direction is vertical, is difficult to effectively disperse and buffer these non-vertical forces, which may cause the equipment to shake or become unstable during operation. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a carton flattening device.

[0005] The cardboard box flattening device provided by this utility model adopts the following technical solution:

[0006] A carton flattening device includes a frame, a top plate, a hydraulic cylinder, a fixed plate, a pressure plate, and a buffer assembly. The top plate is mounted on the frame, the hydraulic cylinder is fixed to the top plate, the piston rod of the hydraulic cylinder passes through the top plate and is connected to the fixed plate, and the buffer assembly is disposed between the pressure plate and the fixed plate, the buffer assembly being disposed at an angle.

[0007] Preferably, the buffer assembly includes a connecting rod, a slider, a slide bar, and a spring. The pressure plate is provided with staggered grooves. Two sets of slide bars are provided, and the two sets of slide bars are staggered in the slide grooves. Each set of slide bars is provided with a set of two sliders. The spring is fitted onto the slide bar. One end of the spring is fixedly connected to the inner wall of the slide groove, and the other end of the spring abuts against the slider. One end of the connecting rod is hinged to the slider, and the other end of the connecting rod is hinged to the bottom of the fixed plate.

[0008] Preferably, the slider is provided with a connector, and the connecting rod is hinged to the connector.

[0009] Preferably, a fixing block is provided at the bottom of the fixing plate, and a second connector is provided on the fixing block, with one end of the connecting rod hinged to the second connector.

[0010] Preferably, the pressure plate is provided with a guide post, and the fixing plate is provided with a corresponding guide hole. The guide post passes through the guide hole, and a limit plate is provided at one end of the guide post that passes through the guide hole.

[0011] Preferably, a second spring is sleeved on the outside of the guide post, the upper part of the second spring abuts against the fixing plate, and the bottom of the second spring abuts against the pressure plate.

[0012] In summary, this utility model has at least one of the following beneficial technical effects:

[0013] 1. When the hydraulic cylinder pushes the fixed plate downward until the pressure plate squeezes the carton, the connecting rod pushes the slider to slide on the slide bar. The slider pushes the spring to deform, which plays a buffering role. The design of the inclined connecting rod can make the force more reasonably decomposed in the transmission process. When the pressure plate is subjected to a vertical upward reaction force, through the inclined connecting rod, this force can be effectively decomposed into a force that the transverse spring can withstand. This decomposition method makes the force transmission more in line with the force characteristics of the spring and improves the buffering efficiency.

[0014] 2. Spring 2 can act as a secondary buffer. When the carton material is hard or the thickness is uneven, a large reaction force is generated during the flattening process. The buffer component will first perform the main buffering, and Spring 2 will be compressed to provide additional buffering effect. This multi-stage buffering design can reduce the transmission of vibration and make the equipment more stable during operation. Attached Figure Description

[0021] This utility model discloses a carton flattening device. (Refer to...) Figure 1-2A carton flattening device includes a frame 1, a top plate 2, a hydraulic cylinder 3, a fixed plate 4, a pressure plate 5, and a buffer assembly 6. The top plate 2 is mounted on the frame 1, and the hydraulic cylinder 3 is fixed to the top plate 2. The piston rod of the hydraulic cylinder 3 passes through the top plate 2 and is connected to the fixed plate 4. A buffer assembly 6 is disposed between the pressure plate 5 and the fixed plate 4. The buffer assembly 6 is obliquely arranged and includes a connecting rod 61, a slider 62, a sliding rod 63, and a spring 64. The pressure plate 5 has staggered grooves 7. Two sets of sliding rods 63 are staggered within the grooves 7. Each set of sliding rods 63 has two sliders 62. The spring 64 is sleeved on the sliding rod 63, and one end of the spring 64 is fixedly connected to the inner wall of the groove 7. The other end of spring 64 abuts against slider 62. One end of connecting rod 61 is hinged to slider 62, and the other end of connecting rod 61 is hinged to the bottom of fixed plate 4. With this design, when hydraulic cylinder 3 pushes fixed plate 4 downward until pressure plate 5 squeezes the carton, connecting rod 61 pushes slider 62 to slide on slide rod 63. Slider 62 pushes spring 64 to deform, which plays a buffering role. The design of inclined connecting rod 61 can make the force more reasonably decomposed in the transmission process. When pressure plate 5 is subjected to vertical upward reaction force, through inclined connecting rod 61, this force can be effectively decomposed into a force that the transverse spring 64 can withstand. This decomposition method makes the force transmission more in line with the force characteristics of spring 64 and improves the buffering efficiency.

[0022] A connector 8 is provided on the slider 62, and the connecting rod 61 is hinged to the connector 8. A fixing block 9 is provided at the bottom of the fixing plate 4, and a connector 10 is provided on the fixing block 9. One end of the connecting rod 61 is hinged to the connector 10. A guide post 11 is provided on the pressure plate 5, and a guide hole is provided on the fixing plate 4. The guide post 11 passes through the guide hole, and a limit plate 13 is provided at the end of the guide post 11 that passes through the guide hole. A spring 12 is sleeved on the outside of the guide post 11. The upper part of the spring 12 abuts against the fixing plate 4, and the bottom of the spring 12 abuts against the pressure plate 5. With this design, the spring 12 can act as a secondary buffer. When the material of the carton is hard or the thickness is uneven, and a large reaction force is generated during the flattening process, the buffer assembly 6 will first perform the main buffering, and the spring 12 will be compressed to provide additional buffering effect. This multi-stage buffering design can reduce the transmission of vibration and make the equipment more stable during operation.
