[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] This utility model provides an automatic calendar rack dispenser device, referring to... Figures 1 to 4As shown, the machine includes a frame 1, with a hopper 2 on the upper part of the frame 1. A material support plate 21 is horizontally parallel to each other on both sides of the bottom of the hopper 2. A vertically upward-facing side baffle plate 22 is provided on the outer side of each material support plate 21 along the front-rear direction. A vertically upward-facing front baffle post 23 is provided at the front end of each material support plate 21. A discharge gap is left between the lower end of the front baffle post 23 and the upper surface of the material support plate 21. The position of the front baffle post 23 is adjustable in the vertical direction. Before each operation, the front baffle post 23 is adjusted to a suitable height so that the discharge gap between the lower end of the baffle post 23 and the material support plate 21 only allows one piece of cardboard to pass through. A vertically upward-facing rear baffle post 24 is provided in the middle of each material support plate 21. The position of the rear baffle post 24 is adjustable in the front-rear direction to accommodate cardboard of different sizes. Below the hopper 2 is a pusher mechanism 3, which includes a linear guide rail 31, a pusher block 32, and a pusher cylinder 33. The linear guide rail 31 is located between and parallel to the two support plates 21. The pusher cylinder 33 is mounted on the frame 1, and the pusher block 32 is driven by the pusher cylinder 33 to reciprocate along the linear guide rail 31. This device can automatically deliver single sheets of cardboard. The storage and pushing parts of the equipment have a simple structure and low cost. The discharge gap at the front of the hopper 2 is adjustable, allowing only one sheet of cardboard to pass through each time. The cardboard is pushed from the bottom of the hopper 2, and material can be added at any time without stopping the machine, saving loading time and effectively improving processing efficiency.

[0020] To accommodate cardboard of different widths, in a preferred embodiment, at least one of the support plates 21 is a movable support plate 211, whose position is adjustable in the left-right direction along the horizontal plane. For details, please refer to [reference needed]. Figure 2 and Figure 3 As shown, a guide rod 11 is provided on the frame 1. The guide rod 11 is perpendicular to the movable material support plate 211 in the horizontal direction. In specific applications, there is a pair of guide rods 11, which are parallel to each other. A slider seat 12 is provided on the guide rod 11, and the movable material support plate 211 is mounted on the slider seat 12. When the slider seat 12 moves along the guide rod 11, the movable material support plate 211 moves left and right along the direction of the guide rod 11. A ball screw 13 parallel to the guide rod 11 is provided on the frame 1. The movable material support plate 211 is connected to the ball screw 13, and the movable material support plate 211 is driven by the ball screw 13 to move along the guide rod 11. The movement and positioning of the movable material support plate 211 by the ball screw 12 has good accuracy and stability.

[0021] In a preferred embodiment, the front end of the side baffle plate 22 is provided with an elongated first mounting hole 221 in the vertical direction, the front baffle post 23 is connected to the first mounting hole 211 by bolts, the middle part of the side baffle plate 22 is provided with an elongated second mounting hole 222 in the horizontal direction, and the rear baffle post 24 is connected to the second mounting hole 222 by bolts. Before each operation, the height of the front baffle post 23 and the front-rear position of the rear baffle post 24 are adjusted to a suitable position.

[0022] For the specific structure of this block 32, please refer to Figure 2 and Figure 3 As shown, the upper surface of the pusher block 32 has stepped portions 321 distributed front and back. The upper surface of the pusher block 32 is slightly higher than the upper surface of the support plate 21 on the rear side of the stepped portion 321, and slightly lower than the upper surface of the support plate 21 on the front side. Cardboard is stacked in the hopper 2, and the upper surface of the support plate 21 supports the bottom of the stack of cardboard. Driven by the pusher cylinder 33, the pusher block 32 moves from back to front. The stepped portion 321 of the pusher block 32 pushes the bottom cardboard forward through the discharge gap at the bottom of the front baffle 23. After being pushed out, it resets backward, and the action is repeated to push out cardboard one by one. In order to reduce the wear on the bottom surface of the cardboard when the pusher block 32 resets backward, in a preferred embodiment, the upper surface of the pusher block 32 has a downward curvature on both the front and rear sides of the stepped portion 321.

[0023] In summary, this utility model can effectively solve the problems of low efficiency of manual feeding of cardboard, complex structure and high cost of automatic feeding device, and has high utilization value and significance, and can be widely promoted and applied.

[0024] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
