DETAILED DESCRIPTION

[0031] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0032] The material tray upper and lower material separation structure, such as Figure 1As shown, it includes a supporting cabinet 1 with a hollow interior. The supporting cabinet 1 body is welded with a hollow pipe and a metal plate. An opening is surrounded on one side of the supporting cabinet 1 and a cabinet door is hinged to close the opening. A symmetrically arranged fixed limit part and a sliding limit part are fixedly connected to the top surface of the supporting cabinet 1. A storage cavity 2 for stacked material trays to be placed is provided between the fixed limit part and the sliding limit part. The distance between the sliding limit part and the fixed limit part is adjustable. By adjusting the distance between the sliding limit part and the fixed limit part, the size of the storage cavity 2 can be stably adjusted, so that the storage cavity 2 can stably place stacked material trays of different sizes, making the storage cavity 2 more adaptable and thereby making the overall structure more adaptable. The adaptability is better. The support cabinet 1 is provided with a pushing structure for driving the material tray to move vertically. Under the action of the pushing structure, the material can be driven to move vertically into the storage chamber 2 or to move vertically out of the storage chamber 2. The pushing structure is provided with a symmetrically arranged feeding part for driving the material tray to pass into or out of the storage chamber 2. The distance between the two feeding parts is adjustable. This arrangement enables the feeding part to adapt to the stable feeding and transportation of material plates of different sizes by adjusting the distance. The pushing structure will send the material tray to or push away from the feeding part during the movement, so that the feeding part can send the outer material tray horizontally to the bottom of the storage chamber 2 or send the material tray out from the inside of the structure horizontally.

[0033] like Figure 1 and Figure 6 As shown, a material port 3 for the feeding plate to enter and exit the material storage chamber 2 is provided between the top side of the feeding portion and the fixed limiting portion and the sliding limiting portion. The vertical height of the material port 3 is adjustable. The material port 3 is used for the feeding plate to move in or out of the bottom of the material storage chamber 2 in the horizontal direction. The vertical height of the material port 3 is set to an adjustable structure, so that the overall structure can adapt to material trays of different thicknesses, making the overall structure more adaptable.

[0034] like Figure 1-Figure 3As shown, the fixed limiting part includes a fixed C-shaped support frame 4, which is fixed to the top surface of the support cabinet 1 by bolt locking, and the sliding limiting part includes a sliding C-shaped support frame 5. The fixed C-shaped support frame 4 and the top of the sliding C-shaped support frame 5 are fixedly connected with two symmetrically arranged L-shaped limiting rods 6, and the L-shaped limiting rods are fixed to the fixed C-shaped support frame 4 and the sliding C-shaped support frame 5 by bolt locking. A connecting block is fixed to the L-shaped limiting rod 6 by bolt locking, and the connecting block is fixed to the fixed C-shaped support frame 4 and the sliding C-shaped support frame 5 by bolt locking. The above-mentioned storage cavity 2 is surrounded by the four L-shaped limiting rods 6, and the inner corners of the four L-shaped limiting rods 6 face the storage cavity 2.The top of the fixed C-shaped support frame 4 and the sliding C-shaped support frame 5 are both fixedly connected with two symmetrically arranged first guide rails 7 by means of bolt locking. The two first guide rails 7 are both slidably connected with a first sliding seat 8. The top surfaces of the two adjacent first sliding seats 8 are fixedly connected with a first sliding plate 9 by means of bolt locking. With the help of the first sliding seat 8 and the first guide rail 7, the stable guidance and limitation of the sliding process of the first sliding plate 9 can be achieved, making the sliding process of the first sliding plate 9 more stable and smooth. The fixed C-shaped support frame 4 and the sliding C-shaped support frame 5 are both fixedly connected with a bolt locking method for driving the first sliding plate 9 to move The first telescopic driving member 10 that slides, the first telescopic driving member 10 is set as a pneumatic telescopic cylinder, the driving end of the first telescopic driving member 10 is fixedly connected with a short connecting plate connected to the first sliding plate 9 by means of bolt locking, and the top surface of the first sliding plate 9 is fixedly connected with a symmetrically arranged hinge seat 11 by means of bolt locking, and a separation block 12 is hinged on the hinge seat 11, and the rotation angle between the separation block 12 and the hinge seat 11 is set as an acute angle, and the separation block 12 is L-shaped as a whole and when it is not subjected to external force, the hinge seat 11 and the side wall of the separation block 12 are abutted and limited, so that the top surface of the separation block 12 is in a state parallel to the top surface of the hinge seat 11, toward The separation block 12 on the side of the material tray is provided with a chamfer. When the structure as a whole realizes the function of collecting materials, when the material tray passes the separation block 12 from bottom to top, it will rotate around its hinge point and realize stable giving way for the material tray to slide upward. When the material tray passes over the separation block 12, under the action of the gravity exerted on the separation block 12 itself, the separation block 12 will rotate around its hinge point and gradually reset. In the process of the separation block 12 gradually resetting, it will pass under the above-mentioned material tray that passes over it, and then in the process of the pushing structure sliding downward, the separation block 12 will realize the tightness and support of the material tray, so that the material tray sent upward by the pushing structure can be stably stacked and stored in the storage chamber 2. When the entire structure achieves its loading function, the stack of trays is placed into the storage chamber 2. The pusher structure applies an upward force to the stack of trays, driving the separation block 12 from below the bottom tray via the first telescopic drive member 10. When the pusher structure drives the joint between the bottom tray and the tray above it, the separation block 12, driven by the first telescopic drive member 10, can penetrate from the joint to the bottom side of the tray above the bottom plate. The pusher structure continues to move downward, allowing the separated tray to stably move to the bottom surface and contact the feeding section, allowing the feeding section to stably feed the tray, thus completing the material separation process of the entire structure.

Through the tightening between the first tightening screw 16 and the second guide rail 13, the stable limiting of the position of the first limit block 15, the second sliding seat 14 and the sliding C-shaped support frame 5 can be achieved, ensuring that the L-shaped limit rod after the adjustment position can be maintained in a stable position, thereby ensuring that the overall shape and state of the storage chamber 2 can be maintained stable.
