[0007] Preferably, the connecting assembly includes a rocker arm and a connecting arm, the rocker arm is mounted on an adjusting rod, and the connecting arm is connected to the free end of the adjusting rod, the free end of the connecting arm being hinged to the bottom of the feeding component;

[0008] The free end of the rocker arm is provided with a movable sliding hole with a waist-shaped cross section, and one end of the connecting arm is slidably connected in the movable sliding hole;

[0009] Multiple sets of L-shaped mounting seats are fixed on another set of mounting plates, and one end of the feeding component is hinged to the mounting seat.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: Reference Figure 1-6An automatic adjustment rejection mechanism for a collating machine is shown, comprising a conveyor body 1. A side plate 5, bolted to the outer wall of the conveyor body 1, can be opened for maintenance of the internal equipment. A primary waste conveying assembly 3 is located on the top surface of the conveyor body 1, and a secondary waste conveying assembly 4 is connected to the outlet of the primary waste conveying assembly 3. To quickly remove defective products from the production line, a feeding mechanism is provided on the conveyor body 1 (located below the inlet of the primary waste conveying assembly 3). To enhance the structural strength of the conveyor body 1, multiple mounting plates 2 are provided inside the conveyor body 1. Holes for the feeding mechanism to operate are provided on the top surface of the conveyor body 1, and the feeding mechanism is mounted on the mounting plates 2.

[0026] A feeding mechanism is also provided between the steering conveying assembly and the conveying body 1.

[0027] In one embodiment of this invention, the feeding mechanism comprises two sets of primary vertical plates 200 and one set of secondary vertical plates 201 on the outer wall of the mounting plate 2. A sleeve roller 7 is rotatably connected to the primary vertical plate 200. A set of electric telescopic cylinders 6 is provided on the outer wall of the primary vertical plate 200. The telescopic end of the electric telescopic cylinder 6 is slidably connected to the inside of the sleeve roller 7. To enable the sleeve roller 7 to rotate on the primary vertical plate 200 when the electric telescopic cylinder 6 is working, a flipping sliding hole 700 communicating with the outside is provided on the inner wall of the sleeve roller 7. The flipping sliding hole 700 is threaded. A protrusion is provided on the telescopic end of the electric telescopic cylinder 6, and the protrusion is slidably connected within the flipping sliding hole 700. When the electric telescopic cylinder 6 is working, the protrusion moves within the flipping sliding hole 700. The roller 7 rotates automatically due to the downward orientation of the protrusion. A coaxial cam 8 is provided on the end face of the roller 7. An adjusting rod 9 is rotatably connected to the secondary vertical plate 201. A torsion spring 10 for resetting is provided on the adjusting rod 9. A feeding component 13 is hinged in the hole. The feeding component 13 is hinged to the mounting base 14 (the mounting base 14 is L-shaped and is fixedly installed on another set of mounting plates 2). The adjusting rod 9 is connected to the feeding component 13 through a connecting assembly. A driven component connected to the cam 8 is provided at the end of the adjusting rod 9. Through the operation of the above structure, the roller 7 rotates and drives the cam 8 to work. With the cooperation of the driven component and the linkage component, the feeding component 13 is flipped, forming a bridge between the waste material and the primary waste material conveying assembly 3.

[0028] As one embodiment of this invention, the connecting assembly: the rocker arm 11 is fixedly mounted on the adjusting rod 9 by bolts, and the free end of the adjusting rod 9 is hinged to the bottom of the feeding component 13 via the connecting arm 12; in order to improve the flexibility of the connecting arm 12, a movable sliding hole 1100 with a waist-shaped cross section is provided at the free end of the rocker arm 11, and one end of the connecting arm 12 is slidably connected in the movable sliding hole 1100; the above structure improves the flexibility of the connecting assembly during operation.

[0029] As one embodiment of this example, the driven component: the rotating part 15 is L-shaped and is fixed to the adjusting rod 9 by bolts. A set of rotating wheels 16 is provided on the rotating part 15. The rotating wheels 16 are slidably connected to the cam 8. The rotating wheels 16 are rotatably connected to the rotating part 15. The purpose is to reduce the friction generated when the cam 8 contacts the rotating wheels 16. A set of telescopic motors 18 is provided above the rotating part 15. A set of connectors is rotatably connected to the end of the telescopic motors 18. The connectors are rotatably connected to the end of the limiting arm 17.

[0030] The limiting arm 17 has a Z-shaped cross-section, and the corner of the limiting arm 17 is rotatably connected to the conveying body 1 (e.g., Figure 3 As shown, the free end of the limiting arm 17 is slidably connected to the rotating part 15. Depending on the usage, it can be determined whether the limiting arm 17 limits the rotating part 15.

[0031] The working principle of this utility model is as follows: The conveyor body 1 transports books and other materials backward. When an unqualified book is detected by an optical sensor on the conveyor body 1, the electric telescopic cylinder 6 is activated. The telescopic end of the working electric telescopic cylinder 6 slides within the sleeve roller 7, and the protrusion at the telescopic end of the electric telescopic cylinder 6 moves within the flipping sliding hole 700, causing the sleeve roller 7 to flip on the primary vertical plate 200. This, in turn, drives the coaxial cam 8 to flip. With the assistance of the torsion spring 10, the adjusting rod 9 flips on the secondary vertical plate 201, causing the end of the adjusting rod 9 to... When the rotating part 15 drives the rotating wheel 16 to abut against the outer wall of the cam 8, the cam 8 drives the adjusting rod 9 to rotate in the opposite direction during the rotation process. The rotating adjusting rod 9 drives the coaxial rocker arm 11 to rotate upward, so that the connecting arm 12, which is slidably connected in the movable sliding hole 1100, moves upward. The upper part of the moving connecting arm 12 pushes the feeding part 13. The feeding part 13 rotates upward with the fixed seat 14 as the center, so that the books and other items pushed here come into contact with the primary waste conveying component 3, and are then sent to the secondary waste conveying component 4 for separation.

[0032] Through the design of the No. 1 telescopic motor 18, when working, its telescopic end drives the limiting arm 17 to rotate around another hinge point of the limiting arm 17, so that the limiting arm 17 can limit or release the limiting of the rotating part 15.

[0033] When internal maintenance of the equipment is required, open the side plate 5 on the side of the conveyor body 1 for observation and maintenance.
