Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, specifically a multi-station cardboard box punching conveyor. Background Technology

[0002] Cardboard boxes are one of the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc. Most existing cardboard boxes have one or more holes, which are mostly punched using cardboard punching machines or corresponding laser punching equipment. The process involves manually placing the cardboard box in the designated position, and then the punching machine or laser punching device directly punches holes in the corresponding locations on the cardboard box.

[0003] Chinese Patent Publication No. CN 113978030 B discloses a multi-station perforation conveyor for cardboard boxes, including a base plate. The base plate is equipped with an extrusion rolling assembly, a transport assembly, a material conveying assembly, and a perforation assembly. The extrusion rolling assembly is used to extrude and straighten the cardboard boxes, the perforation assembly is used to perforate the cardboard, and then the transport assembly transports the perforated cardboard boxes outward.

[0004] When cardboard boxes are transported on transport components, the lack of protective restraints on the cardboard makes it easy for the cardboard to shift during transport, which reduces the accuracy of subsequent punching positions. In addition, the fixed spacing between the side protective plates and the rolling wheels in the aforementioned patent means that punching can only be performed on cardboard of the same specification. Utility Model Content

[0005] The purpose of this invention is to provide a multi-station perforation conveyor for cardboard boxes to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station perforation conveyor for cardboard boxes, comprising a support frame, a conveyor roller mounted on the support frame, a reduction motor fixedly mounted on the side of the support frame, the output end of the reduction motor being fixedly connected to a bidirectional lead screw, an mounting plate being provided on the outer side of the bidirectional lead screw, a rotating roller being provided on the side of the mounting plate, one end of the bidirectional lead screw being fixedly connected to a transmission wheel, the inner wall of the support frame being rotatably connected to one end of a second bidirectional lead screw, a base plate being provided below the second bidirectional lead screw, a movable plate being provided on the outer side of the second bidirectional lead screw, the top of the movable plate being fixedly connected to a limiting plate, one end of the second bidirectional lead screw being fixedly connected to a transmission wheel, the upper surface of the support frame being fixedly connected to a placement frame, a laser perforation tube being provided on one side of the placement frame, the top of the placement frame being fixedly connected to a fixed plate, a laser perforator being fixedly mounted on the top surface of the fixed plate, the support frame being fixedly connected to a collection box, a baffle being provided inside the collection box, and a transmission roller being mounted on the side of the support frame.

[0007] Preferably, the support frame is fixedly connected to the outside of the collection box via an L-shaped plate. The collection box is located below the laser-drilled tube. A rectangular through hole is opened on the side of the collection box, and the collection box slides with the outside of the baffle through the rectangular through hole.

[0008] Preferably, the two sides of the bidirectional lead screw are provided with opposite threads, the mounting plates are symmetrically distributed on both sides of the bidirectional lead screw, the mounting plates are threadedly connected to the outer side of the bidirectional lead screw through threaded holes, the mounting plates are slidably connected to the outer side of the guide rod through circular through holes, and the two ends of the guide rod are fixedly connected to the inner wall of the support frame.

[0009] Preferably, one end of the bidirectional lead screw extends to the outside of the support frame and is fixedly connected to the first transmission wheel, and the first transmission wheel is connected and fixedly connected to the second transmission wheel via a synchronous belt.

[0010] Preferably, the two sides of the bidirectional lead screw are provided with opposite threads, the movable plates are symmetrically distributed on both sides of the bidirectional lead screw, and the movable plates are connected to the outer threads of the bidirectional lead screw through threaded holes.

[0011] Preferably, a rectangular groove is formed on the upper surface of the base plate, and the base plate slides with the outer side of the movable plate through the rectangular groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a motor to rotate a bidirectional lead screw, which drives the mounting plates on both sides to move synchronously outside the guide rod. This allows for adjustment of the spacing of the rotating rollers to meet the punching needs of cardboard of different specifications. The waste generated during punching is collected in a collection box. When cleaning the collection box, the baffle can be pulled out of the collection box by using the handle, reducing the difficulty of cleaning.

[0013] 2. This utility model also limits the conveying of cardboard through the limiting plates on both sides, ensuring that the cardboard is conveyed smoothly and centrally, improving the accuracy of cardboard punching. The rotation of the bidirectional lead screw one causes the transmission wheel one to drive the transmission wheel two to rotate synchronously, which in turn drives the bidirectional lead screw two to rotate, causing the moving plates on both sides to move synchronously with the limiting plates. Thus, the limiting plates can be adjusted to accommodate cardboard of different specifications, improving the linkage effect of the overall structure. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 This utility model provides a technical solution: a multi-station perforation conveyor for cardboard boxes, including a support frame 1, conveyor rollers 2 mounted on the side of the support frame 1, connecting chains mounted on the conveyor rollers 2, adjacent conveyor rollers 2 being connected and fixed together by connecting chains, the connecting chains being connected to a servo motor, the servo motor driving the connecting chains and conveyor rollers 2 to rotate, thereby conveying the cardboard on the surface, the side of the support frame 1 being connected and fixed to a reduction motor 3 by fixing bolts, the output end of the reduction motor 3 being welded and fixed to a bidirectional lead screw 4, the bidirectional lead screw 4 having opposite threads on both sides, and mounting plates 5 symmetrically distributed on both sides of the bidirectional lead screw 4. Mounting plate 5 is threaded to the outer side of the double-acting screw 4 via a threaded hole. Mounting plate 5 is slidably connected to the outer side of the guide rod 7 via a circular through hole. The two ends of the guide rod 7 are welded and fixed to the inner wall of the support frame 1. The rotation of the double-acting screw 4 by the reduction motor 3 drives the mounting plates 5 on both sides to move towards each other, thereby adjusting the spacing of the rotating rollers 6 to meet the transportation needs of cardboard of different specifications. The rotating rollers 6 are installed in the placement frame, which is welded and fixed to the side of the mounting plate 5. One end of the rotating roller 6 is equipped with a rotating shaft, which is rotatably connected to the placement frame. The other end of the rotating roller 6 is connected to a transmission belt, which causes the rotating roller 6 to rotate and transport the cardboard. One end of the bidirectional lead screw 4 extends to the outside of the support frame 1 and is welded and fixed to the transmission wheel 8. The transmission wheel 8 is connected and fixed to the transmission wheel 13 via a synchronous belt. The bidirectional lead screw 9 has opposite threads on both sides. The movable plates 11 are symmetrically distributed on both sides of the bidirectional lead screw 9. The movable plates 11 are threaded to the outside of the bidirectional lead screw 9 via threaded holes. When the bidirectional lead screw 4 rotates, it drives the transmission wheel 13 to rotate synchronously through the transmission wheel 8, thereby allowing the rotating roller 6 and the limiting plate 12 to be adjusted synchronously. This allows for synchronous adjustment of the cardboard specifications, enhancing the actual use effect. The bottom plate 10 is welded and fixed to the inner wall of the support frame 1 at both ends. A rectangular groove is opened on the upper surface of the bottom plate 10. The bottom plate 10 slides with the outer side of the moving plate 11 through the rectangular groove. The groove limits the movement of the moving plate 11, ensuring that the moving plates 11 on both sides move synchronously, thereby conveying the cardboard in the center. The top of the movable plate 11 is welded and fixed to the limiting plate 12. One end of the bidirectional lead screw 9 is welded and fixed to the transmission wheel 13. The upper surface of the support frame 1 is welded and fixed to the placement frame 14. A laser drilling tube 15 is installed on one side of the placement frame 14. The top of the placement frame 14 is welded and fixed to the fixing plate 16. The top surface of the fixing plate 16 is connected and fixed to the laser drilling machine 17. A transmission roller 20 is installed on the side of the support frame 1. Several lamp tubes are installed on the laser drilling tube 15. The aperture of the lamp tubes can be different or adjusted and replaced according to actual use. The support frame 1 is welded and fixed to the outside of the collection box 18 by an L-shaped plate. The collection box 18 is located below the laser-drilled tube 15. A rectangular through hole is opened on the side of the collection box 18, and the collection box 18 slides with the outside of the baffle 19 through the rectangular through hole. Working principle: In use, the cardboard is placed on the surface of the conveyor roller 2. The controller and drive device cause the conveyor roller 2 to rotate and transport the cardboard. During the cardboard transport process, the limiting plates 12 on both sides limit the cardboard to ensure that the cardboard is transported smoothly and centrally, avoiding deviation. When the cardboard moves to below the laser punching tube 15, the laser punching machine 17 punches holes in the cardboard. Then, the rotating roller 6 transports the cardboard to the transmission roller 20 to complete the punching. When it is necessary to punch holes in cardboard of different specifications, the bidirectional lead screw 4 can be rotated by the geared motor 3, so that the mounting plates 5 on both sides move towards each other outside the guide rod 7. The rotating roller 6 can be adjusted according to the width of the cardboard. The rotation of the bidirectional lead screw 4 will drive the transmission wheel 8 to rotate. The transmission wheel 8 uses a synchronous belt to make the bidirectional lead screw 9 and the transmission wheel 13 rotate synchronously. The rotation of the bidirectional lead screw 9 causes the moving plates 11 on both sides to move in the slide groove at the top of the base plate 10, realizing the synchronous adjustment of the limiting plates 12 on both sides, ensuring that the cardboard is centered and limited.
