Abstract
Description
Technical Field
[0001] This utility model belongs to the field of paperboard printing and feeding technology, and in particular, it is a paperboard printing and feeding device. Background Technology
[0002] Currently, the printing industry is developing rapidly. In the printing industry, especially in the color printing industry with high quality requirements, the requirements for paperboard are getting higher and higher. Paperboard should be protected from damage during the transportation process to avoid affecting the printing effect.
[0003] Existing paperboard printing requires intermittent feeding of paperboard using a paperboard feeding device. However, the height of the discharge port in the existing feeding device is fixed, so it can only feed paperboard with the same thickness as the height of the discharge port. If thinner paperboard is fed, paperboard will be stacked during feeding. If the paperboard is too thick, it cannot be fed smoothly. Therefore, there is an urgent need for a paperboard printing feeding device to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide a paperboard printing feeding device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a cardboard printing feeding device, comprising two mounting plates for mounting the cardboard feeding mechanism, a drive roller, and a driven roller. Multiple support columns are fixedly mounted on the bottom of each of the two mounting plates. The drive roller and the driven roller are rotatably mounted between the two mounting plates. A conveyor belt is rotatably connected between the drive roller and the driven roller. Multiple feeding strips for cardboard feeding are fixedly mounted on the top surface of the conveyor belt. A feeding box is erected between the top surfaces of the two mounting plates, and two feeding ports are symmetrically opened on the side wall of the feeding box.
[0006] The top surfaces of both feeding ports are provided with mounting grooves, and a baffle plate is slidably installed inside the mounting groove. Multiple springs are fixedly installed on the top surface of the baffle plate, and the top surfaces of the multiple springs are fixedly installed on the inner wall of the mounting groove.
[0007] The side wall of the baffle plate is symmetrically and longitudinally provided with multiple limiting holes, and the side wall of the feeding box is provided with insertion holes. The insertion holes correspond to the limiting holes, and a plug rod is inserted into the inside of both the limiting holes and the insertion holes.
[0008] Preferably, a lever is fixedly connected to the side wall of the baffle plate, and a strip hole is opened on the side wall of the feeding box and communicates with the mounting groove.
[0009] Preferably, the lever fixedly installed on the side wall of the baffle plate slides through the strip hole and extends to the outside of the feed box.
[0010] Preferably, two limiting blocks are symmetrically fixedly connected to the side wall of the baffle plate, and two limiting grooves are symmetrically opened on the inner wall of the mounting groove.
[0011] Preferably, the limiting blocks fixedly connected to the side wall of the baffle plate are slidably connected to the inside of two limiting grooves opened in the inner wall of the mounting groove.
[0012] Preferably, the inner wall of the feeding box is provided with multiple longitudinally symmetrical strip grooves, and rollers are rotatably installed inside each of the multiple strip grooves.
[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0014] This cardboard printing feeding device benefits from the design of a baffle plate, spring, and insert rod in the feeding port. By adjusting the position of the insert rod in the limiting hole on the baffle plate, the height of the baffle plate can be adjusted. This allows the height of the baffle plate to be adjusted according to the thickness of the cardboard being fed, thereby increasing the applicability of the feeding box.
[0015] This cardboard printing feeding device benefits from the multiple feeding strips on the outside of the conveyor belt. The feeding strips are low in height, so they can feed cardboard of different thicknesses. The feeding strips are made of rubber, so they will not affect the bending of the conveyor belt when it rotates.
[0016] Compared with existing technologies, this paperboard printing feeding device can feed paperboards of different thicknesses by adjusting the height of the baffle plate, thereby improving the applicability of the device. Attached Figure Description

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0025] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.
[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.
[0027] like Figures 1 to 4 The main structure of the paperboard printing feeding device shown is two mounting plates 1 for mounting the paperboard feeding mechanism, a drive roller 3 and a driven roller 4. Multiple support columns 2 are fixedly installed at the bottom of the two mounting plates 1. The drive roller 3 and the driven roller 4 are rotatably installed between the two mounting plates 1. A conveyor belt 5 is rotatably sleeved between the drive roller 3 and the driven roller 4. Multiple feed strips 6 are fixedly installed on the top surface of the conveyor belt 5. Thanks to the multiple feed strips 6 on the outside of the conveyor belt 5, the height of the feed strips 6 is low, so it can feed paperboards of different thicknesses. The feed strips 6 are made of rubber, so they will not affect the bending of the conveyor belt 5 when it rotates. A feed box 7 is set between the top surfaces of the two mounting plates 1. Two feed ports 8 are symmetrically opened on the side wall of the feed box 7.
[0028] The top surfaces of the two discharge ports 8 are provided with mounting grooves 9. A baffle plate 10 is slidably installed inside the mounting groove 9. Multiple springs 11 are fixedly installed on the top surface of the baffle plate 10. The top surfaces of the multiple springs 11 are fixedly installed on the inner wall of the mounting groove 9. Thanks to the setting of the springs 11, the baffle plate 10 can be effectively pushed downward, thereby facilitating the height adjustment of the baffle plate 10.
[0029] The side wall of the baffle plate 10 is symmetrically and longitudinally provided with multiple limiting holes, and the side wall of the feeding box 7 is provided with insertion holes. The insertion holes correspond to the limiting holes, and the insertion holes and the limiting holes are both inserted with insertion rods 12. Thanks to the setting of the baffle plate 10, spring 11 and insertion rods 12 in the feeding port 8, the height of the baffle plate 10 can be adjusted by adjusting the position of the insertion rods 12 inserted into the limiting holes on the baffle plate 10. This allows the height of the baffle plate 10 to be adjusted according to the thickness of the feeding paperboard, thereby improving the applicability of the feeding box 7.
[0030] A lever 13 is fixedly connected to the side wall of the baffle plate 10. A strip hole is opened on the side wall of the feed box 7 and communicates with the mounting groove 9. The lever 13 fixedly installed on the side wall of the baffle plate 10 slides through the strip hole and extends to the outside of the feed box 7. Thanks to the setting of the lever 13, the baffle plate 10 can be easily moved up or down, so as to quickly adjust the baffle plate 10.
[0031] Two limiting blocks 14 are symmetrically fixedly connected to the side wall of the baffle plate 10, and two limiting grooves are symmetrically opened on the inner wall of the mounting groove 9. The limiting blocks 14 fixedly connected to the side wall of the baffle plate 10 are slidably connected to the two limiting grooves opened on the inner wall of the mounting groove 9. Thanks to the setting of the limiting blocks 14, the sliding direction of the baffle plate 10 can be effectively limited, and the stability of the baffle plate 10 can be improved.
[0032] The inner wall of the feeding box 7 is symmetrically provided with multiple strip grooves 15. Rollers 16 are rotatably installed inside the multiple strip grooves 15. Thanks to the multiple rollers 16, the multiple cardboards in the feeding box 7 can be effectively guided, and the cardboard can be easily fed out.
[0033] Working principle
[0034] In use, the cardboard printing feeding device first places the cardboard stacked inside the feeding box 7. Then, the height of the baffle plate 10 is adjusted according to the thickness of the cardboard. First, the two insert rods 12 are pulled out of the limiting hole and the insertion hole. Then, the lever 13 is pushed, which drives the baffle plate 10 to move up or down, thereby adjusting the height of the feeding port 8 in the feeding box 7 to match the thickness of the cardboard, thus improving the applicability of the device. Then, the drive roller 3 is started, which drives the conveyor belt 5 and the driven roller 4 to rotate synchronously, thereby driving the feeding strip 6 to move. When it moves to the feeding port 8, it pushes the cardboard to move. The feeding strip 6 is set at intervals to realize intermittent feeding of the cardboard.
