Description

Technical Field

[0001] This utility model relates to the field of printing equipment, and more specifically, to a paperboard printing device. Background Technology

[0002] A cardboard printing machine is a device specifically designed for printing on cardboard materials. It is widely used in the production of packaging, advertising, and various paper products. These machines are capable of printing high-quality patterns and text on cardboard and are commonly used to produce cartons, display racks, and other paper packaging products.

[0003] Existing cardboard printing machines include a conveyor belt and a printing head located above the conveyor belt. Cardboard is placed on the conveyor belt and conveyed. When the cardboard passes under the printing head, the printing head prints the pattern on the cardboard. Then the cardboard exits the printing machine with the conveyor belt. Usually, a trolley is placed under the cardboard printing machine. After the cardboard falls from the conveyor belt, it will fall onto the trolley. However, the position of the cardboard is prone to change during the fall, which may cause part of the cardboard to protrude from the edge of the trolley or even fall outside the trolley.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a paperboard printing device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cardboard printing device, including a printing machine, wherein the printing machine is provided with a conveyor belt and a printing head, a guide plate is provided on one side of the printing machine, a guide strip is provided on the guide plate along the length direction of the guide plate, a plurality of rollers are rotatably connected to the top surface of the guide strip, two sliding grooves are provided on the bottom surface of the guide plate along the width direction of the guide plate, and a limit plate is slidably connected in each of the two sliding grooves, and a rear plate is fixedly connected to the side of the two limit plates facing each other.

[0007] The present invention is further configured such that: a screw is provided in the sliding groove, one end of the screw is rotatably connected to the inner wall of the sliding groove, and the other end of the screw passes through the limiting plate and protrudes from the side of the guide plate, and the screw is threadedly connected to the limiting plate.

[0008] The present invention is further configured such that the guide plate is transparent at the position above the sliding groove.

[0009] The present invention is further configured such that: a sliding groove is provided on the bottom surface of the limiting plate, and an extension plate is slidably connected in the sliding groove.

[0010] The present invention is further configured such that: a groove with a T-shaped cross-section is provided on the inner wall of the slide, and an insert that is always located in the groove is fixedly connected to one side of the extension plate, and the maximum static friction between the insert and the groove is greater than the weight of the extension plate.

[0011] The present invention is further configured such that a handle groove is provided on the side of the extension plate facing away from the insert.

[0012] The present invention is further configured such that a throttle is fixedly connected to one end of the screw that protrudes from the guide plate.

[0013] In summary, this utility model has the following beneficial effects:

[0014] The guide plate helps the cardboard fall smoothly, and its support ensures that the cardboard reaches the designated collection area in the best possible condition. The rollers significantly reduce the friction between the cardboard and the guide strip, reducing resistance during movement. The two limiting plates prevent the cardboard from protruding from the left and right sides of the trolley, and the rear plate prevents it from protruding from the side of the trolley facing the printing machine. The limiting plates and rear plate ensure that the cardboard falling onto the trolley is not easily exposed outside the trolley, making it less likely for the cardboard to collide with other items when the trolley is pushed.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Paperboard printing equipment, such as Figure 1 and Figure 2As shown, the system includes a printing machine 1, which contains a conveyor belt 2 and a printing head. A guide plate 3 is located on one side of the printing machine 1, and guide strips 4 are arranged along the length of the guide plate 3. Multiple guide strips 4 are arranged in a linear array along the width of the guide plate 3. Several rollers are rotatably connected to the top surface of each guide strip 4. Two sliding grooves 5 are formed on the bottom surface of the guide plate 3 along its width. Limiting plates 6 are slidably connected to both sliding grooves 5. A rear plate 7 is fixedly connected to the side of each limiting plate 6 facing the printing machine 1. The rear plate 7 is flush with the side of the limiting plates 6 facing the printing machine 1. Before printing, the position of the trolley on the side of the printer is controlled according to the falling position of the cardboard. After adjusting the trolley position, the position of the two limiting plates 6 is controlled so that the downward projections of the limiting plates 6 and the rear plate 7 are both on the trolley. After the cardboard is printed by the printing head... The cardboard will be conveyed along the conveyor belt 2 to the guide plate 3. The guide plate 3 is tilted downwards, allowing the cardboard to fall along it. The guide plate 3 helps the cardboard fall smoothly, and its support ensures that the cardboard reaches the designated collection area in the best condition. The rollers can significantly reduce the friction between the cardboard and the guide strip 4, reducing the resistance of the cardboard during movement. After falling from the guide plate 3, the cardboard will fall between two limiting plates 6. The setting of the two limiting plates 6 prevents the cardboard from being exposed on the left and right sides of the cart. The setting of the rear plate 7 prevents the cardboard from being exposed on the side of the cart facing the printing machine 1. Since the side of the cart facing away from the printing machine 1 is the pull rod on the cart, the cardboard falling on the cart is also unlikely to be exposed on the side of the cart facing away from the printing machine 1. The setting of the limiting plates 6 and the rear plate 7 ensures that the cardboard falling on the cart is not easily exposed outside the cart, so that the cardboard is less likely to collide with other items when people push the cart.

[0021] like Figure 2 and Figure 3As shown, a screw 8 is provided in the sliding groove 5. One end of the screw 8 is rotatably connected to the inner wall of the sliding groove 5, and the other end of the screw 8 passes through the limiting plate 6 and protrudes from the side of the guide plate 3. The screw 8 is threadedly connected to the limiting plate 6. Both sliding grooves 5 have screws 8. The sliding grooves 5 have a guiding and limiting function on the upper end of the limiting plate 6. When people rotate the screw 8, the limiting plate 6 can be moved along the length of the sliding groove 5. The screw 8 has a self-locking function so that the limiting plate 6, after moving, is not easy to continue sliding in the sliding groove 5. The design allows the positions of the two limiting plates 6 to accommodate trolleys of different widths. The guide plate 3, located above the sliding groove 5, is transparent, allowing its position to be directly observed from above. This ensures that the cardboard falls between the two limiting plates 6. The bottom surface of the limiting plate 6 has a sliding groove, within which an extension plate 9 is slidably connected. The extension plate 9 can slide up and down along the height of the limiting plate 6. The extension plate 9 is used to abut the trolley, ensuring that there is no space for the cardboard to fall between the trolley and the limiting plate 6.

[0022] like Figure 3 As shown, a T-shaped groove 10 is formed on the inner wall of the chute. An insert 11, which is always located within the groove 10, is fixedly connected to one side of the extension plate 9. The maximum static friction between the insert 11 and the groove 10 is greater than the weight of the extension plate 9. The length of the groove 10 is set along the height of the limiting plate 6. The cross-section of the extension plate 9 is L-shaped, so that the extension plate can not only block the gap between the limiting plate 6 and the trolley, but also block the gap between the rear plate 7 and the trolley. In this embodiment, there are two grooves 10, which are located on the limiting plate 6 and the rear plate 7, respectively. The cross-section of the extension plate 9 is T-shaped, which increases the contact area with the insert 11. The inner wall of the groove 10 is relatively rough, which increases the friction between the inner wall of the groove 10 and the insert 11. This ensures that the extension plate 9 can only slide along the groove under the action of external force. A handle groove 12 is provided on the side of the extension plate 9 facing away from the insert 11. The handle groove 12 provides a force point for people to slide the extension plate 9, making it convenient for people to slide the extension plate 9. A throttle 13 is fixedly connected to the end of the screw 8 that protrudes from the guide plate 3. The throttle 13 provides a force point for people to turn the screw 8, making it convenient for people to turn the screw 8.
