[0010] (III) Beneficial Effects Compared with the prior art, the present invention provides an automatic feed adjustment device for an extruder, which has the following advantages: This automatic feed adjustment device for extruder comprises an installation mechanism, a connecting mechanism, a storage mechanism, and an adjustment mechanism. The fixed frame and U-shaped plate are slidably connected to form the basic frame. The inclined surface of the wedge block engages with the vertical plate to form a self-locking structure. When the vertical plate is pressed down, the wedge block is compressed, pushing the U-shaped plate outwards. When the vertical plate reaches its lowest point, a telescopic spring provides a counter-force, ensuring the wedge block remains in close contact with the vertical plate, thus completing the installation of the storage mechanism. When disassembling the connecting mechanism and the storage mechanism, the U-shaped rod pulls down the U-shaped plate, causing the wedge block to move and releasing the fibers from the vertical plate, allowing the entire connecting frame to be moved upwards. This design separates the connecting pipe from the fixed cylinder, facilitating installation, disassembly, maintenance, and replacement. The frame and lifting plate are connected by a slide rail, and a fixed spring provides preload to keep the clamping block pressed against the horizontal plate. When the horizontal plate moves left or right to the set position, the specific position of the storage cylinder is adjusted. The position of the storage cylinder relative to the discharge hole of the connecting frame is adjusted as needed, thereby changing the size of the discharge hole. After adjustment, the clamping block automatically engages in the positioning groove of the horizontal plate under the action of the spring, thus achieving the left and right position of the storage cylinder. The design of the pull rod allows manual overcoming of the spring force to lift the lifting plate, quickly releasing the clamping state to adjust the position of the storage cylinder, achieving the purpose of adjustable feeding size.

[0021] The anti-clogging mechanism 9 includes a top frame 91. The top frame 91 is fixedly installed on the top of the storage cylinder 71. A motor frame 92 is fixedly installed on the top of the top frame 91. A rotary motor 93 is fixedly installed on the inner side of the motor frame 92. A rotating shaft 94 extending to the inner side of the storage cylinder 71 is fixedly installed at the output shaft of the rotary motor 93. A stirring rod 95 is fixedly installed on the outer side of the rotating shaft 94. A stirring blade 96 located at the bottom of the stirring rod 95 is fixedly installed on the outer side of the rotating shaft 94. When material is added into the storage cylinder 71, the rotary motor 93 of the anti-clogging mechanism 9 is activated. The rotating shaft 94 drives the stirring rod 95 to rotate, the material is turned over, and the stirring blade 96 scrapes away the material accumulated at the bottom, thus achieving the purpose of preventing clogging and facilitating user operation.

[0022] In use, place the operating table 1 on a horizontal working surface, start the motor 32 of the drive assembly 3 to run at low speed, check the coaxiality of the screw conveyor 33 and the conveying cylinder 22, and stop after confirming that there is no friction noise. Pull the pull rod 85 upward to compress the fixing spring 86 of the lifting plate 84 and drive the locking block 87 to disengage from the positioning groove of the horizontal plate 81. Hold the pull ring 82 and move the storage cylinder 71 left and right. Adjust it to the required position by the sliding guide of the limiting block 72 in the strip hole 63. Release the pull rod 85, and the locking block 87 will re-lock into the positioning groove under the action of the spring to complete the fixation. Add material to the storage cylinder 71 to no more than 80% of its volume, and start the rotation of the anti-blocking mechanism 9. Motor 93 drives shaft 94 to rotate stirring rod 95 and stirring blade 96. The material flowability is monitored through observation window. Motor 32 of drive assembly 3 is started. Screw conveyor 33 conveys material from feed pipe 23 of feed cylinder 22 to extruder inlet. The speed of motor 32 is adjusted by frequency converter to achieve feed rate adjustment of 0.5-15kg / min. When it is necessary to stop feeding, the motor speed can be reduced to below 5rpm instead of stopping completely to prevent material accumulation and blockage. The elasticity of extension spring 55 of mounting mechanism 5 is checked regularly. If the compression exceeds 30% of the original length, it needs to be replaced. When disassembling, all motors should be stopped and power should be disconnected first.

[0023] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0024] In summary, this automatic feeding adjustment device for an extruder, through the installation mechanism 5, connecting mechanism 6, storage mechanism 7, and adjusting mechanism 8, forms a basic frame by sliding connection between the fixed frame 51 and the U-shaped plate 52. The inclined surface of the wedge block 53 cooperates with the vertical plate 64 to form a self-locking structure. When the vertical plate 64 is pressed down, the wedge block 53 is squeezed and pushes the U-shaped plate 52 outward. When the vertical plate 64 moves to the bottom, the telescopic spring 55 provides a reverse elastic force to ensure that the wedge block 53 and the vertical plate 64 always maintain close contact, thus completing the installation of the storage mechanism 7. When disassembling the connecting mechanism 6 and the storage mechanism 7, the U-shaped plate 52 is pulled down by the U-shaped rod 54, which moves the wedge block 53, releasing the fiber of the wedge block 53 to the vertical plate 64. This allows the connecting frame 62 to be moved upward as a whole, separating the connecting pipe 61 from the fixed cylinder 4, achieving the purpose of convenient installation, disassembly, maintenance, and replacement. The frame 83 and The lifting plate 84 is connected by a slide rail, and the fixed spring 86 provides pre-tightening force to keep the locking block 87 pressed against the horizontal plate 81. When the horizontal plate 81 moves left or right to the set position, the specific position of the storage cylinder 71 is adjusted. According to the requirements, its position with the discharge hole of the connecting frame 62 is adjusted, thereby changing the size of the discharge hole. After the adjustment is completed, the locking block 87 automatically locks into the positioning groove of the horizontal plate 81 under the action of the spring, realizing the left and right position of the storage cylinder 71. The design of the pull rod 85 allows the lifting plate 84 to be lifted manually to overcome the spring force, quickly release the locking state to adjust the position of the storage cylinder 71, and realize the purpose of adjustable feeding size. This solves the problem that it is inconvenient to install and disassemble the device during use, which makes the operation inconvenient when the device needs to be maintained or replaced, increases the difficulty of operation for the staff, and makes it inconvenient to adjust the feeding size of the raw materials according to the actual processing situation.
