Description

Technical Field

[0001] This utility model relates to the field of carton printing and conveying technology, specifically a conveying device for a carton printing machine. 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. Most cardboard boxes are printed with pictures or related information about the product, providing consumers with intuitive product information. This requires cardboard box printing machines to print relevant patterns or text on the cardboard boxes.

[0003] Chinese Patent CN221939698U discloses a feeding device for a carton printing machine, relating to the field of carton printing technology. It includes a base plate and a storage box. A fixing frame is fixedly installed on the top of the base plate. The output shaft of the first electric push rod is fixedly mounted on the printing machine. A tray is provided inside the storage box. A pressure plate is fixedly mounted on the output shaft of the second electric push rod, and the pressure plate is positioned directly above the tray. This invention, through the use of the tray and pressure plate, allows for a slower conveying speed, ensuring that the printed cartons fall smoothly into the storage box. The tray supports the printed cartons. Activating the second electric push rod pushes the pressure plate downwards to press the cartons, ensuring that multiple cartons are pressed together, thus improving the storage capacity and efficiency of the storage box. Lifting two pull rings raises the tray, ensuring that multiple cartons are lifted simultaneously, improving the efficiency and convenience of carton removal.

[0004] The aforementioned patent has some shortcomings: it involves placing materials onto a conveyor belt for transportation and printing during the transportation process. However, during use, when the printing press moves downwards to apply pressure to the materials for printing, the conveyor belt will sag downwards, leaving the bottom of the materials suspended in the air. The conveyor belt cannot support the bottom of the materials, leading to printing failure. Additionally, the process of the printing press moving downwards to apply pressure to the materials can deform them. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide a conveying device for a carton printing machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conveying device for a carton printing machine, comprising a machine base, a frame vertically installed on the top of the machine base, and a lifting plate provided inside the frame, with driving components provided at both ends of the lifting plate, a connecting plate installed inside the frame, and a bottom supporting component provided on the connecting plate;

[0007] The bottom support assembly includes a support plate and guide columns. The support plate is disposed within the frame, and guide columns are vertically installed at the bottom of the support plate. The bottoms of the guide columns slide through the connecting plate.

[0008] As a further embodiment of this utility model: the driving component includes a vertical plate, an active trapezoidal block and a passive trapezoidal block. The passive trapezoidal blocks are symmetrically arranged on the top of the connecting plate. The vertical plates are installed at both ends of the bottom of the lifting plate, and active trapezoidal blocks are installed on the side of the vertical plates that are close to each other. The active trapezoidal blocks are used to push the passive trapezoidal blocks.

[0009] As a further embodiment of this utility model: a guide rod is installed inside the frame, and a passive trapezoidal block is slidably installed through the guide rod.

[0010] As a further embodiment of this utility model: a reset spring is sleeved on the guide rod, and the reset spring is located between the two passive trapezoidal blocks.

[0011] As a further embodiment of this utility model: an electric push rod is vertically installed at the top of the frame, and a lifting plate is installed at the output end of the electric push rod, with the printing machine body installed at the bottom of the lifting plate.

[0012] As a further embodiment of this utility model: guide bodies are vertically and symmetrically installed on the top of the lifting plate, and the top of the guide bodies slides through the frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the conveying device of the carton printing machine is equipped with a pallet and a guide column. During the process of transporting the material to the bottom of the printing machine body for printing, the pallet moves up to the top of the conveyor belt and is located directly below the material. The pallet can support the material directly below, ensuring that the printing machine body can properly squeeze and print the material, thereby improving the printing yield and ensuring the effectiveness of printing.

[0014] In addition, the conveying device of this carton printing machine is also equipped with a vertical plate, an active trapezoidal block, and a passive trapezoidal block. The vertical plate is driven to move down by the downward lifting plate. During the downward movement of the vertical plate, the active trapezoidal block is driven to move down. The two downward moving active trapezoidal blocks can push the two passive trapezoidal blocks closer to each other. The two passive trapezoidal blocks pushing the two ends of the pallet push the pallet up to the top position inside the conveyor belt, thereby supporting the top of the conveyor belt and thus supporting the material transported at the top of the conveyor belt.

[0019] 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.

[0020] Please see Figure 1-3 The present invention provides a technical solution: a conveying device for a carton printing machine, including a machine base 1, a frame 3 vertically installed on the top of the machine base 1, and a lifting plate 5 provided inside the frame 3, with driving components provided at both ends of the lifting plate 5, a connecting plate 13 installed inside the frame 3, and a bottom lifting component provided on the connecting plate 13.

[0021] The bottom support assembly includes a support plate 11 and guide posts 12. The support plate 11 is provided inside the frame 3, and the guide posts 12 are vertically installed at the bottom of the support plate 11. The bottom of the guide posts 12 slides through the connecting plate 13.

[0022] The drive assembly includes a vertical plate 6, an active trapezoidal block 7, and a passive trapezoidal block 8. The passive trapezoidal blocks 8 are symmetrically arranged on the top of the connecting plate 13. The vertical plates 6 are installed at both ends of the bottom of the lifting plate 5, and the active trapezoidal blocks 7 are installed on the side of the vertical plates 6 that are close to each other. The active trapezoidal blocks 7 are used to push the passive trapezoidal blocks 8.

[0023] Specifically, by activating the electric push rod 4, the lifting plate 5 is driven to move downward. The moving lifting plate 5 drives the vertical plate 6 to move downward. During the downward movement of the vertical plate 6, the active trapezoidal block 7 moves downward. The two moving active trapezoidal blocks 7 can push the two passive trapezoidal blocks 8 closer to each other. The two passive trapezoidal blocks 8 push the two ends of the pallet 11, thereby lifting the pallet 11 to the top position inside the conveyor belt 2 and supporting the top of the conveyor belt 2, thus supporting the material transported at the top of the conveyor belt 2.

[0024] The contact portions of the active trapezoidal block 7 and the passive trapezoidal block 8 are both chamfered. When the passive trapezoidal block 8 does not push the pallet 11, the two passive trapezoidal blocks 8 support the pallet 11. The contact portions of the passive trapezoidal block 8 and the pallet 11 are both chamfered.

[0025] Furthermore, a guide rod 9 is installed inside the frame 3, and a passive trapezoidal block 8 is slidably installed through the guide rod 9;

[0026] Specifically, during the reciprocating movement of the passive trapezoidal block 8, the guide rod 9 installed through the passive trapezoidal block 8 can guide the moving passive trapezoidal block 8, ensuring that the passive trapezoidal block 8 can move normally along the designed installation path.

[0027] Furthermore, a return spring 10 is sleeved on the guide rod 9, and the return spring 10 is located between the two passive trapezoidal blocks 8;

[0028] Specifically, when the active trapezoidal block 7 does not apply a pushing force to the passive trapezoidal block 8, the two passive trapezoidal blocks 8 are pushed away from each other by the reset spring 10, thereby resetting the passive trapezoidal blocks 8. At this time, the support plate 11 falls into the space between the two passive trapezoidal blocks 8 at a constant speed under gravity, and the guide post 12 can guide and restrict the support plate 11.

[0029] Furthermore, an electric push rod 4 is vertically installed at the top of the frame 3, and a lifting plate 5 is installed at the output end of the electric push rod 4. The printing machine body 15 is installed at the bottom of the lifting plate 5.

[0030] Specifically, by activating the electric push rod 4, the lifting plate 5 is moved down. The moving lifting plate 5 then moves the printing machine body 15 down to print the material transported on the top of the conveyor belt 2. During this process, the pallet 11 is simultaneously raised to support the bottom of the material. The pallet 11 and the printing machine body 15 are adjusted and coordinated to work synchronously.

[0031] Furthermore, guide bodies 14 are vertically and symmetrically installed on the top of the lifting plate 5, and the top of the guide bodies 14 slides through the frame 3;

[0032] Specifically, during the up-and-down movement of the lifting plate 5, the electric push rod 4, vertically installed at the top of the lifting plate 5, slides through the frame 3, thereby ensuring the stability of the printing press body 15 and the vertical plate 6 in their up-and-down movement.

[0033] Working principle: When using the conveyor device of this carton printing machine, the starting electric push rod 4 drives the lifting plate 5 to move downward. The moving lifting plate 5 drives the vertical plate 6 to move downward. During the downward movement of the vertical plate 6, the active trapezoidal block 7 moves downward. The two moving active trapezoidal blocks 7 can push the two passive trapezoidal blocks 8 closer to each other. The two approaching passive trapezoidal blocks 8 push the two ends of the pallet 11, thereby lifting the pallet 11 to the top position inside the conveyor belt 2, supporting the top of the conveyor belt 2, and thus supporting the material transported on the top of the conveyor belt 2. During this process, the moving lifting plate 5 drives the printing machine body 15 to move downward to print the material transported on the top of the conveyor belt 2.
