[0028] like Figure 2-3 The stirring device 3 includes a stirring shaft 31 and stirring blades 32. The stirring blades 32 are located in the stirring chamber 1 and are fixed on the stirring shaft 31. The left end of the stirring shaft 31 extends out and is located in the transmission chamber 5.

[0029] like Figure 3-4 The screw assembly 4 includes a screw shaft 41 and two screws 42, with the screw shaft 41 and the two screws 42 being connected in a transmission manner; the main body of the feed hopper 2 is a cylindrical chamber, such as... Figure 3 The left end of the feed hopper 2 is detachable, and the right end is connected to the discharge pipe 21. The two screws 42 of the screw device 4 are detached from the left end of the feed hopper 2 and installed in the feed hopper 2. The cross-sectional dimension of the discharge pipe 21 is smaller than that of the feed hopper 2, so as to form a sunken space in the feed hopper 2 below the two screws 42. The feed trough 22 is fixedly installed in the sunken space. The feed trough 22 is located below the two screws 42 and is elongated. Figure 4 The upper surface of the guide trough 22 is a double arc-shaped groove, which is adapted to the two screws 42. A 2mm gap is maintained between the edges of the two screws 42 and the double arc-shaped groove. The lower surface of the guide trough 22 is an arc surface. The lower surface of the guide trough 22 is attached to and fixedly installed with the inner wall of the sinking space of the guide hopper 10.

[0030] like Figure 3 Two screws 42 extend to the right into the discharge pipe 21, and the screw shaft 41 is located in the transmission chamber 5. (See also...) Figure 5 The discharge pipe 21 and two screws 42 are included. The cross-section of the discharge pipe 21 is set to an "8" shape that matches the overall outline of the two screws 42.

[0031] like Figure 6-7 The transmission chamber 5 includes a shaft end mounting plate 51, a shaft end hinge plate 52, a shaft end connecting plate 53, a power end mounting plate 54, a power end hinge plate 55, and a power end connecting plate 56.

[0032] Reference Figure 1 The shaft end connecting plate 53 and the power end connecting plate 56 can be opened and connected by locking buckle 57. When locking buckle 57 fixes the power end connecting plate 56 and the shaft end connecting plate 53, the shaft end mounting plate 51, shaft end hinge plate 52, shaft end connecting plate 53, power end mounting plate 54, power end hinge plate 55, and power end connecting plate 56 together form a fixed box. When locking buckle 57 is released, the power end connecting plate 56 separates from the shaft end connecting plate 53, and the joint between the power end mounting plate 54, power end hinge plate 55, and power end connecting plate 56 and the shaft end hinge plate 52 rotates to form a box that can be flipped open.

[0033] like Figure 7 The shaft end mounting plate 51, shaft end hinge plate 52, and shaft end connecting plate 53 are fixedly mounted on the base 8. The left end of the stirring shaft 31 passes through the shaft end mounting plate 51, and the left end of the screw shaft 41 also passes through the shaft end mounting plate 51.

[0034] like Figure 3 , 6 -7. The transmission mechanism 6 and the power mechanism 7 are mounted on the power end mounting plate 54. The power mechanism 7 includes a drive motor 71 and a reducer 72. The output shaft of the drive motor 71 is connected to the reducer 72. The transmission mechanism 6 includes a first output shaft 61, a second output shaft 62, a drive wheel 63, and a driven wheel 64. The drive wheel 63 is fixed on the first output shaft 61, and the driven wheel 64 is fixed on the second output shaft 62. The reducer 72 is connected to the first output shaft 61. The drive wheel 63 and the driven wheel 64 are sprockets. The drive wheel 63 drives the driven wheel 64 to rotate through the chain 63.

[0035] The first output shaft 61 is connected to the stirring shaft 31 of the stirring device 3 via an openable first coupling structure, and the second output shaft 62 is connected to the screw shaft 41 of the screw device 4 via an openable second coupling structure.

[0036] Specifically, the first coupling structure includes two interlocking claw-type connecting blocks 65, such as... Figure 8The claw-type connecting block 65 includes a claw seat 651 and three claw teeth 652. The claw seat 651 is cylindrical and has a circular hole 653 along its central axis. A keyway 654 is also provided at the circular hole 653. The first output shaft 61 and the stirring shaft 31 are respectively inserted into the circular holes 653 of the two claw-type connecting blocks 65. The claw teeth 652 are arranged on one end face of the claw seat 651. The three claw teeth 652 are evenly distributed with the center of the end face of the claw seat 651 as the center and the center of the arc of the end face of the claw seat 651 as the center. The angle occupied by each claw tooth 652 is less than 60 degrees.

[0037] like Figure 2 , 6 It also includes a wiring device 9, which includes a mounting plate 91, a junction box 92, and a wiring rod 93. The junction box 92 and the wiring rod 93 are fixedly mounted on the mounting plate 91, and the mounting plate 91 is hinged to the base 8. Figure 6 The mounting plate 91 rotates downwards away from the transmission chamber 5, facilitating the opening of the transmission chamber 5; as Figure 2 The mounting plate 91 is rotated upward and fixed. The mounting plate 91 is located outside the transmission chamber 5. On the one hand, it protects the transmission chamber 5. On the other hand, the wiring device 9 connects to the external power supply, control signal and feedback signal, so that the whole machine can operate stably.

[0038] like Figure 6-7 The transmission mechanism 6 and the power mechanism 7 are mounted on the power end mounting plate 54, thus forming a flip-up module that can be separated from the stirring shaft 31 and the screw shaft 41. During separation, the transmission mechanism 6 and the power mechanism 7 free up their original space, as shown in the reference image. Figure 6-7 In this state, the workers removed the screw assembly 4 entirely from the feed hopper 2 through the opening of the transmission chamber 5, and then installed a new screw assembly 4, combined with... Figure 3 The screws 42 of the screw assembly 4 are inserted into the guide hopper 2, with both screws 42 positioned above the double-arc groove of the guide channel 22. The right end of the screws 42 is located in the discharge pipe 21. Then, the screw assembly 4 is fixedly connected to the guide hopper 2, and the replacement of the screw assembly 4 is completed. Rotate the power end mounting plate 54, which drives the transmission mechanism 6 and the power mechanism 7 to rotate. (Refer to...) Figure 7 , Figure 1-3 The first output shaft 61 is connected to the stirring shaft 31 of the stirring device 3 through the first coupling structure, and the second output shaft 62 is connected to the screw shaft 41 of the screw device 4 through the second coupling structure. Finally, the locking buckle 57 is connected and locked, and the transmission chamber 5 forms a closed box for subsequent production work.

[0039] When working, refer to, for example Figure 1-3In this state, the power mechanism 7 is connected to the stirring device 3 and the screw device 4 via the transmission mechanism 6. The stirring blades 32 of the stirring device 3 rotate in the stirring chamber 1 to mix the materials in the stirring chamber 1. The materials enter the guide chamber 2 through the opening at the lower end of the stirring chamber 1. The materials are located on the double arc-shaped groove of the guide trough 22. The guide trough 22 in the stirring chamber 1 is used to prevent the materials from accumulating and hardening at the bottom of the stirring chamber 1. Hardened and deteriorated materials reduce the qualified rate of the output materials. The two screws 42 of the screw device 4 are matched with the double arc-shaped groove. The two screws 42 rotate to easily and conveniently transport the materials on the double arc-shaped groove through the discharge pipe 21. There are no dead corners in the guide chamber 2 where materials cannot be transported.

[0040] In summary, the present invention provides a feeder with an easy-to-replace twin-screw mechanism. The transmission chamber adopts a flip-open structure design. When the transmission chamber is closed, it connects the power mechanism to the mixing device and the screw device via the transmission mechanism. When the transmission chamber is opened, it separates the power mechanism, transmission mechanism, mixing device, and screw device, while creating space for easy replacement of the screw device. The entire machine has a stable and reliable structure, and the screw device replacement is simple and convenient for operators.

[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0042] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
