The material suction assembly further comprises a anti-blocking cloth bag and an elastic element. The cloth bag wraps the elastic element. The cloth bag and the elastic element are installed below the air suction machine and inside the material suction cavity. After using the above technical solution, when adding material, first start the material suction assembly. When pouring the material, the material suction assembly will suck the material to prevent the material from diffusing out. Then cover the baffle and turn off the material suction assembly to allow the material to be stirred in the feeding barrel by the stirring assembly. This can greatly reduce the waste of material and reduce the loss.
[0005] However, the above-mentioned device still has the following defects:
[0006] Although the above-mentioned device can adsorb the powder through the material suction assembly, it needs to additionally increase the material suction electronic element, which undoubtedly increases the production cost.

[0015] The utility model has the advantages that:
[0016] 1. This utility model, through the combined action of an L-shaped slide rail, a cover plate, a spring chamber, and a compression spring, can reduce material waste. When the operator pushes material into the hopper from above, the external force pushes the cover plate to slide horizontally along the L-shaped slide rail, and the compression spring is compressed and stores energy.

Detailed Implementation
[0023] See Figures 1 to 4This utility model discloses a feeding device for a diffuser plate extruder, comprising a feed hopper 1, a mixing chamber 2, an L-shaped slide rail groove 3, a cover plate 4, a spring chamber 5, a compression spring 6, and a mixing assembly 7. The lower end of the feed hopper 1 is connected to the mixing chamber 2. The upper end of the feed hopper 1 is symmetrically provided with L-shaped slide rail grooves 3 on both sides. The two L-shaped slide rail grooves 3 are connected to a cover plate 4. The two ends of the cover plate 4 are embedded in the L-shaped slide rail grooves 3 by rollers to form a horizontal sliding degree of freedom. The ends of the L-shaped slide rail grooves 3 are provided with spring chambers 5. The spring chambers 5 are provided with compression springs 6. One end of the compression spring 6 is fixed to the end wall of the L-shaped slide rail groove 3, and the other end of the compression spring 6 is connected to the end wall of the cover plate 4. The mixing chamber 2 is provided with a mixing assembly 7 inside.
[0024] It should be noted that the L-shaped slide rail groove 3 in this application is a tapered guide groove (the width at the end narrows), which can automatically correct the position of the cover plate 4 and ensure that it is completely aligned with the opening of the feed hopper 1 when closed; and the edge of the cover plate 4 in this application is pre-embedded with a hollow silicone sealing strip (not shown in the figure), which is deformed by the pressure of the cover plate 4 when closed, filling the gap between the cover plate 4 and the feed hopper 1. At the same time, the cross-section of the hollow silicone sealing strip (not shown in the figure) is designed as a trapezoidal protrusion structure. When closed, the protrusion first contacts the edge of the feed hopper 1, and gradually flattens it as the pressure of the cover plate 4 increases, forming a progressive seal.
[0025] See Figure 1 The cover plate 4 has a transparent acrylic observation window 41 in the center, which makes it easy to observe the inside of the feed hopper 1.
[0026] See Figure 2 The spring chamber 5 is provided with a guide post 51, and the compression spring 6 is sleeved on the guide post 51. By setting the guide post 51, the extension and retraction trajectory of the compression spring 6 can be constrained, avoiding jamming caused by lateral load.
[0027] See Figure 3 The stirring assembly 7 includes a stirring shaft 71, a stirring rod 72, crushing teeth 73, and a secondary gear 74. The stirring shaft 71 is rotatably located in the center of the mixing tank 2. The stirring rod 72 is symmetrically arranged above the stirring shaft 71, and the crushing teeth 73 is symmetrically arranged below the stirring shaft 71. The bottom end of the stirring shaft 71 passes through the bottom of the mixing tank 2 and is rotatably connected to the secondary gear 74. When the secondary gear 74 rotates, it drives the stirring shaft 71 to rotate. The stirring shaft 71 drives the stirring rod 72 and the crushing teeth 73 to rotate, thereby efficiently mixing the materials.
[0028] See Figure 3The mixing tank 2 is provided with an L-shaped support plate 8 below it, and a motor 9 is provided below the L-shaped support plate 8. The output shaft of the motor 9 passes through the top of the L-shaped support plate 8 and is rotatably equipped with a main gear 10. The main gear 10 is meshed with the secondary gear 74. The input end of the motor 9 is connected to an external power source through an electric wire. When the motor 9 starts, it drives the output shaft to rotate, which in turn drives the main gear 10 to rotate, and the main gear 10 drives the secondary gear 74 to rotate.
[0029] See Figure 3 The inner wall of the mixing tank 2 is provided with several scrapers 11. By setting the scrapers 11, they can cooperate with the stirring rod 72 and the crushing teeth 73 to stir, thereby improving the mixing effect.
[0030] See Figure 1 and Figure 3 The bottom of the mixing tank 2 is provided with a feeding trough 12, and the feeding trough 12 is connected to a feeding pipe 13. After the material is well mixed in the mixing tank 2 by the mixing component 7, it can be transported from the feeding trough 12 to the extruder for processing through the feeding pipe 13.
[0031] The working process of this utility model:
[0032] In the operation of the feeding device of the diffuser plate extruder of this utility model, when the operator pushes the material into the feed hopper 1 from above, the external force pushes the cover plate 4 to slide horizontally along the L-shaped slide rail groove 3, and the compression spring 6 is compressed and stored energy. At this time, the cover plate 4 opens and the material falls into the feed hopper 1. When the external force is removed, the compression spring 6 releases its elasticity and pushes the cover plate 4 to slide back to the initial position, thereby realizing the automatic opening and closing of the cover plate 4. Then the material falls into the mixing tank 2 for mixing. Then the motor 9 is started, and the motor 9 drives the output shaft to rotate. The output shaft drives the main gear 10 to rotate, the main gear 10 drives the secondary gear 74 to rotate, and the secondary gear 74 drives the stirring shaft 71 to rotate. The stirring shaft 71 drives the stirring rod 72 and the crushing tooth 73 to rotate, thereby efficiently mixing the material. After the material is well mixed in the mixing tank 2 by the stirring assembly 7, it can be transported to the extruder for processing through the feeding pipe 13 on the feeding trough 12.
[0033] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.
