Description

Technical Field

[0001] This utility model relates to the field of paper packaging box processing technology, and in particular to a paper packaging box processing, packing and pressing mechanism. Background Technology

[0002] Paper packaging boxes refer to commodity packaging made primarily of paper or cardboard. Due to their advantages such as being environmentally friendly, recyclable, and relatively low-cost, they are widely used in various industries. The main types of paper packaging boxes include corrugated cardboard boxes and single-layer cardboard boxes. Corrugated cardboard boxes, with their excellent compression resistance and cushioning properties, have become an indispensable part of logistics and transportation.

[0003] After the paper packaging boxes are produced, multiple paper packaging boxes need to be stacked and packaged. In order to pack the paper packaging boxes more tightly and without taking up too much space, a pressing mechanism is used to press down on the paper packaging boxes during stacking and packaging to ensure the packaging effect. However, the existing pressing mechanism mostly uses hydraulic cylinders and other pushing mechanisms to press the paper packaging boxes. However, the pressure in the single vertical direction can only compress the stacking space of the paper packaging boxes. When stacking paper packaging boxes, misalignment between adjacent paper packaging boxes is inevitable. During packaging, the outward protruding paper packaging boxes are easily deformed or even damaged by the external force during packaging.

[0004] Therefore, a paper packaging box processing, packing, and pressing mechanism is proposed. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the single pressing direction and the tendency for paper packaging boxes to be damaged during the packing process due to misalignment. Therefore, this invention proposes a paper packaging box processing and packing pressing mechanism.

[0006] In view of this, the present invention provides a paper packaging box processing and packing pressing mechanism, including a U-shaped seat with the opening facing downward, support plates vertically installed on both sides of the bottom of the U-shaped seat, a rectangular frame below the support plates, and a pushing mechanism vertically installed at the top center of the frame, the pushing mechanism being fixed on the support plate.

[0007] The frame has slots at both ends and corresponding lead screws above the slots. The two lead screws are connected to a bidirectional motor at one end, and the bidirectional motor is fixed to the inner wall of the frame by a bracket. The other end of the lead screws is rotatably mounted on the inner wall of the frame. A strip plate is threaded onto the lead screws, and the other end of the strip plate passes through the slot.

[0008] Preferably, strip-shaped mounting holes are provided at both ends of the top of the U-shaped base.

[0009] Preferably, a first guide shaft is provided parallel to the side of the pushing mechanism, one end of the first guide shaft is fixed to the top of the frame, and the other end of the first guide shaft slides through the support plate.

[0010] Preferably, a second guide shaft is provided parallel to the bottom of the frame, the end of the second guide shaft slides through the bottom of the strip plate, and a limit plate is installed on the end of the second guide shaft.

[0011] Preferably, pressure rollers are provided at the bottom of both sides of the frame, and the ends of the pressure rollers are rotatably connected to the ends of the frame.

[0012] Preferably, slide rails are installed on both sides of the strip groove, and a groove corresponding to the slide rail is opened on the side of the strip plate, so that the strip plate can be slidably connected to the slide rail through the groove.

[0013] Preferably, a reinforcing plate is installed on the top of the support plate, with one side of the reinforcing plate fixed to the U-shaped seat and the other side of the reinforcing plate fixed to the support plate.

[0014] Compared with the prior art, this utility model provides a paper packaging box processing, packing and pressing mechanism, which has the following beneficial effects:

[0015] 1. This utility model uses two opposing strip plates that move relative to each other under the operation of a lead screw. This allows the frame to press down on the stacked paper packaging boxes while simultaneously straightening the sides of the boxes, thus preventing misalignment during packing and damage to the edges of the boxes.

[0016] 2. This utility model uses two sets of pressing mechanisms arranged on both sides of the packaging position, which can simultaneously press the two ends of the paper packaging box when packaging, thereby improving the pressing effect of the pressing mechanism on the paper packaging box, and also making the packaging and binding position of the paper packaging box tighter, thus improving the binding effect of the binding rope on the paper packaging box when packaging.

[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] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Please see Figures 1 to 4 A paper packaging box processing and packing pressing mechanism includes a U-shaped base 1 with its opening facing downwards. Both ends of the top of the U-shaped base 1 have strip-shaped mounting holes 2. In use, the U-shaped base 1 can be removed and placed on a paper packaging box packing machine (such as...). Figure 4 On the crossbeam (pointed to by the middle arrow A), the bolt can be taken and passed through the mounting hole 2 to fasten the U-shaped seat 1 to the crossbeam, thereby fastening the U-shaped seat 1 to the crossbeam.

[0025] like Figure 1 and Figure 2 As shown, support plates 3 are vertically installed on both sides of the bottom of the U-shaped base 1, and a reinforcing plate 16 is installed on the top of the support plate 3. One side of the reinforcing plate 16 is fixed to the U-shaped base 1, and the other side of the reinforcing plate 16 is fixed to the support plate 3, providing additional connection support between the support plate 3 and the U-shaped base 1, thereby strengthening the stress strength of the support plate 3.

[0026] A rectangular frame 4 is provided below the support plate 3. A pushing mechanism 5 is vertically installed at the top center of the frame 4. The pushing mechanism 5 is fixed on the support plate 3. In actual use, the pushing mechanism 5 is one of a hydraulic cylinder, an electric push rod, or a pneumatic cylinder. After the stacked paper packaging boxes are placed on the packing machine, the pushing mechanism 5 will push the frame 4 down to press the paper packaging boxes, thereby pressing the paper packaging boxes together.

[0027] Furthermore, in order to make the lifting and lowering of the frame 4 more stable, a first guide shaft 15 is provided parallel to the side of the pushing mechanism 5. One end of the first guide shaft 15 is fixed to the top of the frame 4, and the other end of the first guide shaft 15 slides through the support plate 3 to guide the lifting and lowering of the frame 4, so that the frame 4 can always keep a straight line when lifting and lowering.

[0028] It should be noted that, since the paper packaging boxes need to be loaded and unloaded on the baling machine, in order to facilitate the movement of the paper packaging boxes on the baling machine, the support surface of the paper packaging boxes on the baling machine is composed of multiple rotating rollers arranged at intervals. After the frame 4 presses the paper packaging boxes, in order not to affect the loading and unloading of the paper packaging boxes, pressure rollers 12 are provided on both sides of the bottom of the frame 4. The ends of the pressure rollers 12 are rotatably connected to the ends of the frame 4, so that the pressure rollers 12 replace the bottom surface of the frame 4 to contact the paper packaging boxes. Under the rotation of the pressure rollers 12, the pressing effect on the paper packaging boxes is maintained, and the loading and unloading of the paper packaging boxes is not affected.

[0029] After the paper packaging box is pressed together by frame 4, as follows Figure 2 and Figure 3 As shown, strip grooves 6 are provided at the lower ends of both ends of the frame 4, and lead screws 7 are provided above the strip grooves 6. The two lead screws 7 are connected to a bidirectional motor 8 at their relatively close ends, and the bidirectional motor 8 is fixed to the inner wall of the frame 4 through a bracket. The other ends of the lead screws 7 are rotatably installed on the inner wall of the frame 4. Under the operation of the bidirectional motor 8, the lead screws 7 at both ends can be driven to rotate synchronously. A strip plate 9 is threaded onto the lead screw 7. The other end of the strip plate 9 is set through the strip groove 6. When the lead screw 7 rotates, it can drive the strip plates 9 located at both ends of the frame 4 to move relative to each other.

[0030] Specifically, after the U-shaped seat 1 is installed on the crossbeam of the packing machine, the bottom of the strip plate 9 will pass through the gap between the rollers of the packing machine. When the paper packaging box is placed on the roller, the two strip plates 9 on the same frame 4 are furthest apart. At this time, the paper packaging box is also located between the two strip plates 9. Therefore, after the frame 4 presses on the paper packaging box, the screw 7 will start to drive the strip plate 9 to move, so that the strip plate 9 leans against the side of the paper packaging box and relatively squeezes the two sides of the paper packaging box that are being packed and bound, so as to straighten the paper packaging box and prevent the packaging box from being misaligned, thus preventing damage due to insufficient stress during packing.

[0031] To ensure the stability of strip 9 during movement, such as Figure 1As shown, a second guide shaft 10 is provided parallel to the bottom of the frame 4. The end of the second guide shaft 10 slides through the bottom of the strip plate 9, providing guidance for the linear movement of the strip plate 9 and providing support for the bottom of the strip plate 9, reducing the possibility of bending of the strip plate 9 due to insufficient support when it comes into contact with the paper packaging box. At the same time, in order to prevent the second guide shaft 10 from slipping off the strip plate 9 when the two strip plates 9 are relatively far apart, a limit plate 11 is installed on the end of the second guide shaft 10. In actual use, the length of the second guide shaft 10 corresponds to the length of the frame 4. When the strip plate 9 moves, the limit plate 11 will limit the movement of the strip plate 9 on the second guide shaft 10 to prevent the strip plate 9 from detaching from the second guide shaft 10.

[0032] It should be noted that, in order to prevent the lead screw 7 from causing the strip plate 9 to deflect when it rotates, slide rails 13 are installed on both sides of the strip groove 6, and a groove 14 corresponding to the slide rail 13 is opened on the side of the strip plate 9, so that the strip plate 9 is slidably connected to the slide rail 13 through the groove 14, which limits the movement of the strip plate 9 on the lead screw 7, so that the strip plate 9 always moves in a straight line along the axis of the lead screw 7, ensuring that the force of the two strip plates 9 on the paper packaging box is always set relative to each other, thereby making the straightness of the paper packaging box more stable.

[0033] 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.
