Description

Technical Field

[0001] This utility model relates to a fiber crushing discharge hopper structure. Background Technology

[0002] Fireproof boards and other sheet structures made from blended fibers require crushing of the fibers before processing. The crushed fibers fall from the hopper onto a conveyor belt, where they are then woven into fiber cloth using various mixing and weaving equipment. This fiber cloth is then stacked and pressed. During the fiber crushing and discharge process, due to entanglement between the fibers, the fibers emerge as a clump after the hopper opens, making it difficult to discharge in a measured quantity and hindering subsequent fiber mixing. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a fiber crushing discharge hopper structure that can disperse the agglomerated fibers into small clusters during the discharge process.

[0004] To achieve this objective, the structure adopted in this utility model is: a fiber crushing discharge hopper structure, including a discharge frame, the top opening of the discharge frame facing the crusher, and discharge claws symmetrically arranged at the bottom of the discharge frame. The discharge claws are connected to the bottom of the discharge frame through a connecting shaft. A cylinder is provided on the discharge frame and connected to the discharge claws. Each discharge claw has a blade on its edge.

[0005] The bottom of the discharge claw is inclined upwards towards the two discharge claws to form a slope. The two discharge claws have an opening on the opposite side. When the two discharge claws are combined, they form a container with an opening at the top. The left discharge claw is called the left discharge claw, and the right discharge claw is called the right discharge claw. The left discharge claw has a left blade on the edge of its slope, and the right discharge claw has a right blade on the edge of its slope. When the left discharge claw and the right discharge claw are combined, the left blade and the right blade are combined vertically.

[0006] When the left and right discharge claws separate, the distance between the left and right blades gradually decreases from one end to the other.

[0007] A baffle is installed on each of the left and right sides of the discharge rack, and an anti-collision strip is installed on each side of each discharge claw. The anti-collision strips are located on both sides of the baffle.

[0008] An observation door is provided on the side of the discharge rack, and the observation door is connected to the discharge rack by a hinge.

[0009] Its beneficial effects are: The structure of this utility model is reasonable and ingenious. After the fiber is broken, it enters from the top of the discharge rack and accumulates on the two discharge claws. When the material is discharged, the two discharge claws open and close under the action of the cylinder. When the discharge claws open, the fiber clumps fall down. When the discharge claws close, the blades cut the fiber clumps, so that the fiber falls into smaller clumps on the feeding belt, which makes it easier to quantitatively feed and mix with the fiber.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0015] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; a fixed connection can be welding or adhesive bonding. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0017] like Figure 1 , Figure 2The fiber crushing discharge hopper structure shown includes a discharge frame 1. The top opening of the discharge frame 1 faces the crusher, and the bottom opening expands to both sides in a trumpet shape. Inside the trumpet-shaped expansion at the bottom of the discharge frame 1, two discharge claws 3 are symmetrically arranged on both sides. The top side of each discharge claw 3 is connected to the discharge frame 1 via a connecting shaft. The discharge claw 3 can rotate around the connecting shaft. A cylinder is provided on both sides of each discharge claw 3 on the discharge frame 1. The cylinder is connected to the discharge claw 3. The piston rod of the cylinder pushes and pulls to open and close the two discharge claws 3. Each discharge claw 3 has a blade on its edge. During the opening and closing of the discharge claw 3, the internal fiber clumps fall and are cut. Thus, the fibers stored in the discharge claw 3 after being discharged from the crusher are divided as they fall, making the fiber clumps more dispersed on the conveyor belt, which is convenient for subsequent quantitative feeding and fiber mixing.

[0018] The bottom of the discharge claw 3 slopes upwards towards the space between the two discharge claws 3, forming an inclined surface. This allows the falling fibers to be pushed as close as possible to the space between the two discharge claws 3, minimizing the amount of fiber in the middle of the discharge claws and preventing large clumps of fiber from accumulating and hindering their fall after the discharge claws 3 separate. The two discharge claws 3 have openings on opposite sides, forming a container with an open top when they are joined together. Figure 3 As shown, the left discharge claw is the left discharge claw 31, and the right discharge claw is the right discharge claw 32. The left discharge claw 31 has a left blade 33 on its inclined edge, and the right discharge claw 32 has a right blade 34 on its inclined edge. When the left discharge claw 31 and the right discharge claw 32 are combined, the left blade 33 and the right blade 34 are combined vertically. In this way, when the two discharge claws are closed, the left blade 33 and the right blade 34 form a shearing force, which is beneficial to cutting the fiber clump.

[0019] When the left discharge claw 31 and the right discharge claw 32 separate, the distance between the left blade 33 and the right blade 34 gradually decreases from one end to the other, making shearing easier and reducing the pressure on the cylinder.

[0020] A baffle 5 is provided on each of the left and right sides of the discharge rack 1. A collision protection strip 4 is provided on each of the two sides of each discharge claw 3. The collision protection strip 4 is located on both sides of the baffle 5. A proximity switch is provided on the collision protection strip 4. When the discharge claw 3 is closing, the proximity switch is triggered after the collision protection strip 4 touches the baffle 5, so that the cylinder stops moving and avoids excessive closing or loose closing.

[0021] An observation door 2 is provided on the side of the discharge rack 1. The observation door 2 is connected to the discharge rack 1 by a hinge, and the inside of the discharge gripper 3 can be inspected through the observation door 2.

[0022] Based on the above description and inspired by this utility model, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
