Description

Technical Field

[0001] The utility model relates to the technical field of paper feeding devices, in particular to a paper feeding device with a cardboard positioning mechanism. Background Art

[0002] Cardboard, also known as board paper, is a thick paper sheet made by processing various pulp and composed of interwoven fibers. The difference between cardboard and paper is usually distinguished by basis weight and thickness. Generally, cardboard with a basis weight exceeding 250 g / m2 and a thickness greater than 0.5 mm is called cardboard.

[0003] During the processing of cardboard, it is necessary to convey the cardboard. The traditional cardboard paper feeding device is usually a conveyor belt. Multiple cardboard sheets are placed on the conveyor belt in batches manually, and the cardboard is conveyed to a specific position by the conveyor belt.

[0004] However, when multiple cardboard sheets are placed on the conveyor belt in batches manually for conveyance, it is difficult to keep multiple cardboard sheets in a horizontal position on the conveyor belt during manual operation, which easily leads to the phenomenon that multiple cardboard sheets placed on the conveyor belt are conveyed obliquely, and the cardboard cannot be conveyed neatly. Content of the Utility Model

[0005] The purpose of the utility model is to provide a paper feeding device with a cardboard positioning mechanism aiming at the defects and deficiencies of the prior art.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions: A paper feeding device with a cardboard positioning mechanism includes a frame, a conveyor belt arranged on the frame for conveying cardboard, a driving mechanism arranged between the conveyor belt and the frame for controlling the conveyor belt to convey cardboard, and further includes two fixed seats symmetrically arranged at the left and right ends of the frame respectively, two inclined seats symmetrically arranged on the two fixed seats respectively for placing cardboard and allowing the cardboard to slide onto the conveyor belt after being placed, and two limiting plates arranged between the two inclined seats and the two mounting plates respectively for limiting the left and right ends of the cardboard when the cardboard is placed on the two inclined seats. The two fixed seats are close to each other, the two limiting plates are close to each other, and the two inclined seats are close to each other.

[0007] Further improvement is: Installation openings are formed on the two inclined seats, and a plurality of rotating wheels are rotatably arranged in the installation openings on the two inclined seats.

[0008] Further improvement is: The inclination angle of the inclined seat is 5° - 25°.

[0009] Further improvements are as follows: Two auxiliary limiting plates for limiting the left and right ends of the cardboard are provided on the two limiting plates when the cardboard slides from the inclined seat onto the conveyor belt. The two auxiliary limiting plates are flush with the limiting plates, and the two auxiliary limiting plates are arranged at the front end of the limiting plates.

[0010] Further improvements are as follows: A driving mechanism for driving the limiting plate to drive the inclined seat to move left or right is provided between the two fixed seats and the two limiting plates.

[0011] Further improvements are as follows: The driving mechanism includes two driving through holes respectively formed through the two fixed seats, two driving screws respectively threadedly connected to the two fixed seats and located in the driving through holes. One end of the two driving screws is located on one side of the fixed seat and abuts against the limiting plate. Guide members for maintaining the horizontal movement of the limiting plate left or right are respectively provided between the two limiting plates and the two fixed seats. The other end of the driving screw is located on the other side of the fixed seat. At least four tension springs for pulling the limiting plate to abut against one end of the driving screw are respectively provided between the two limiting plates and the two fixed seats.

[0012] Further improvements are as follows: The guide members include two guide slots respectively formed on the two fixed seats and symmetrically arranged front and back, and guide rods with one end provided on each limiting plate and the other end slidably engaged with the guide slots. The guide slots and the guide rods are arranged horizontally.

[0013] Further improvements are as follows: Driving handwheels for facilitating the manual control of the forward or reverse rotation of the driving screws are provided at the other ends of the two driving screws.

[0014] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows: When it is necessary to place multiple cardboard sheets on the conveyor belt in batches for conveying, the cardboard sheets are placed on the two inclined seats, and the cardboard sheets slide from the inclined seats onto the conveyor belt. At this time, the limiting plates can limit the left and right ends of the cardboard sheets, so that the cardboard sheets slide onto the conveyor belt at a certain position, and it is not easy to cause the phenomenon that multiple cardboard sheets placed on the conveyor belt are inclined during conveying. The positions of multiple cardboard sheets placed on the conveyor belt can be continuously positioned, and the cardboard sheets can be conveyed neatly.

[0015] Further effects: The rotating wheel can reduce the friction between the cardboard sheet and the inclined seat when the cardboard sheet is placed on the inclined seat, so that the cardboard sheet can slide from the inclined seat onto the conveyor belt more quickly.

[0016] Further effects: When the cardboard sheet slides from the inclined seat onto the conveyor belt, the auxiliary limiting plates can continuously limit the left and right sides of the cardboard sheet, further preventing the cardboard sheet from tilting on the conveyor belt during sliding.

[0017] Further effect: When the two driving screws rotate forward, one end of each of the two driving screws pushes the two limiting plates to drive the two inclined seats to approach each other, and the tension springs are gradually stretched to generate elastic potential energy, and the limiting plates are kept pulled to abut against one end of the driving screws; when the two driving screws rotate in reverse, the two tension springs gradually release the elastic potential energy, so that as the driving screws move, the two limiting plates are gradually pulled respectively to drive the two inclined seats to move away from each other, so that the distance between the two inclined seats can be adjusted according to the width of the support plate.

[0018] Further effect: When the driving screw pushes the limiting plate to move left and right, the guide rod slides left or right in the guide slot, which can prevent the phenomenon of deviation or inclination during the movement of the limiting plate driving the inclined seat.

[0027] The inclination angle of the inclined seat 5 is 5° - 25°. The larger the inclination angle, the greater the sliding speed of the cardboard on the inclined seat 5.

[0028] Two auxiliary limiting plates 9 for limiting the left and right ends of the cardboard when the cardboard slides from the inclined seat 5 onto the conveyor belt 2 are arranged on the two limiting plates 6. The two auxiliary limiting plates 9 are flush with the limiting plates 6, and the two auxiliary limiting plates 9 are arranged at the front ends of the limiting plates 6.
