Description

Technical Field

[0001] The utility model relates to the field of packaging box manufacturing equipment, in particular to a packaging box paperboard collecting and sorting equipment. Background Art

[0002] In the packaging box manufacturing industry, the collection and sorting of cardboard is an important link. High-quality cardboard collection and sorting can not only improve the efficiency of subsequent processing, but also ensure the quality of the final product. In this process, it is necessary to ensure a certain degree of neatness of the cardboard to facilitate subsequent die-cutting, folding and other process flows. The Chinese utility model patent in the prior art: CN208666698U, a paper collection device of a printing press, provides a relevant technical solution, which discloses a paper sorting tooth row at the rear end of the paper collection table and side sorting cardboards on both sides, and performs three-sided swing sorting on the pile of paper on the paper collection table, effectively sorting the pile of paper on the paper collection table, which is conducive to improving the efficiency of subsequent transportation and the quality of paper die-cutting. For packaging box cardboard, our company currently uses the equipment of the above patent. However, during use, the equipment has some problems. One of the most important problems is that the edge of the cardboard is easily damaged. Specifically, when the paper sorting tooth row performs the swinging back and forth paper patting action, due to its relatively rigid action, it will cause repeated pressure on the edge of the cardboard, which may cause the edge of the cardboard to wear or even break under long-term action. This not only reduces the aesthetics of the cardboard, but also affects the effect of subsequent processing (such as die-cutting and folding). Summary of the invention

[0003] Purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a packaging box cardboard collection and sorting device to solve the problem of edge damage during cardboard collection.

[0004] The technical scheme of the utility model comprises: a frame, a central axis is rotatably connected to the frame, a plurality of straight-line arranged paper-feeding teeth are fixedly installed on the central axis, a swing piece and a rotating active cam are installed on the frame; the outer peripheral contour of the active cam comprises an arc contour with a gradually increasing diameter and a radial surface contour, the radial surface contour is arranged along the radial direction of the active cam and is connected end to end with the maximum diameter position and the minimum diameter position of the arc contour; one end of the swing piece is hinged to the frame, and the other end is connected to the frame through a compression tension spring; an input pressure arm and an output pressure arm are respectively convexly provided on two opposite side directions of the swing piece, the input pressure arm contacts the outer peripheral contour of the active cam and is closely attached to the active cam through the compression tension spring; a power storage cam and a release cam are fixedly installed on the central axis, the release cam is connected to the frame through a release tension spring, and the power storage cam has a lug, the lug is matched with the output pressure arm to overcome the elastic force of the release tension spring under the drive of the output pressure arm.

[0005] By adopting the above technical solution, the active cam drives the swinging member to swing, so that the output pressure arm drives the power storage cam to overcome the elastic force of the release spring to store energy until the output pressure arm is separated from the power storage cam. At this time, the release cam uses the release spring to release the stored energy, and drives the paper sorting teeth to sort the cardboard in an elastic patting manner. Through the improved swinging method of the paper sorting teeth, the damage to the edge of the cardboard caused by the rigid paper patting action in the traditional device is avoided. The power storage and release process is softer, and the improved sorting action is smoother and more controllable, reducing the direct pressure on the edge of the cardboard, thereby reducing damage to the edge of the cardboard; in addition, the sorting force and speed can be adjusted according to the specifications of the cardboard (such as thickness, hardness, etc.), and the parameters of the release spring can be adjusted. It can easily adapt to cardboards of different specifications without affecting the overall performance of the equipment, enhancing the adaptability of the equipment to different cardboard materials, thereby expanding the scope of application of the equipment.

[0006] In a possible design, a soft spring pad is installed on the contact surface between the paper handling tooth row and the paperboard.

[0007] With the above design, the soft spring pad can provide a buffering effect when the paper sorting teeth row contacts the cardboard, reduce the pressure and friction on the edge of the cardboard caused by the rigid contact, and effectively avoid edge wear or breakage. Moreover, through the buffering effect of the soft spring pad, the cardboard can move more smoothly when being sorted, reduce the misalignment between the cardboards, thereby improving the neatness of the cardboard stacking and thus improving the sorting quality.

DETAILED DESCRIPTION

[0014] like Figure 1-5 The packaging box cardboard collecting and sorting device shown in the figure comprises a frame 1 and a paper receiving platform 2. The frame 1 is rotatably connected with a central shaft 3. A plurality of linearly arranged paper sorting teeth rows 4 are fixedly mounted on the central shaft 3. The paper sorting teeth rows 4 are located beside the paper receiving platform 2. The paper receiving platform 2 receives the cardboard 21 conveyed by the previous process. The frame 1 is equipped with a pendulum 6 and a rotating active cam 5. The active cam 5 is driven by a motor to rotate around its center. The outer contour of the active cam 5 includes an arc contour 51 and a radial surface contour 52. The arc contour 51 is in a gradually changing arc shape with a gradually increasing diameter, so that the outer contour size of the active cam 5 gradually increases. The radial surface contour 52 is arranged along the radial direction passing through the center of the active cam 5, and the radial surface contour 52 is respectively connected end to end with the maximum diameter position and the minimum diameter position of the arc contour 51; one end of the pendulum 6 is hinged to the frame 1, and the other end is connected to the frame 1 through a compression spring 61; an input pressure arm 62 and an output pressure arm 63 are respectively convexly provided on two opposite sides of the swing direction of the pendulum 6, and the input pressure arm 62 is in contact with the outer contour of the active cam 5 and is tightly pressed against the outer contour of the active cam 5 through the tension of the compression spring 61. A power storage cam 7 and a release cam 8 are fixedly mounted on the central shaft 3. The release cam 8 is connected to the frame 1 via a release tension spring 81. The outer contour of the power storage cam 7 has a raised lug 71. The lug 71 abuts against the output pressure arm 63 to overcome the elastic force of the release tension spring 81 driven by the output pressure arm 63. The working motion process is: first, the motor drives the active cam 5 to rotate, and under the action of the elastic tension of the compression spring 61, the input pressure arm 62 of the swing member 6 is pressed against the outer contour of the active cam 5, and the input pressure arm 62 gradually swings to one side along the trajectory of the contact arc contour 51, and then returns to its original position instantly after passing through the radial surface contour 52; secondly, during the swinging process of the swing member 6, the output pressure arm 63 gradually presses against the lug 71 of the power storage cam 7, and drives the power storage cam 7 to rotate a certain angle. At this time, the release spring 81 is tightened and expanded through the release cam 8, so that the central axis 3 can store energy, and the paper sorting tooth row 4 will also be forced to swing away from the paper receiving table 2; finally, the output pressure arm 63 returns quickly due to the input pressure arm 62 passing through the radial contour, and is out of contact with the lug 71. The central axis 3 is released under the tension of the release spring 81, and the paper sorting tooth row 4 returns and swings, thereby elastically beating and arranging the cardboard 21 on the paper receiving table 2. In addition, according to the thickness and hardness of the paperboard 21 , the parameters of the release spring 81 can be adjusted, and a suitable release spring 81 can be selected to prevent the paperboard 21 from being damaged.

[0015] A soft spring pad 41 is pasted and installed on the contact surface between the paper-feeding tooth row 4 and the paperboard 21. The soft spring pad 41 serves as the main contact position of the paperboard 21 and plays a certain buffering role, reducing the pressure and friction caused by rigid contact on the edge of the paperboard 21, and further avoiding edge wear or breakage.
