DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Example 1

[0021] Reference Figure 1-2 , an automatic sorting and rejecting device for hard food materials used in food processing, comprising a conveying box 1, a sorting slot 2 is provided on the upper end surface of the conveying box 1, and the bottom slot wall of the sorting slot 2 is inclined, a conveying belt 3 is provided on the inner bottom wall of the sorting slot 2, and the upper end surface of the conveying belt 3 has a plurality of grooves, so that the material can be prevented from tilting when being transported on the conveying belt 3, and a discharge port 12 corresponding to the conveying belt 3 is provided on the lower side slot wall of the sorting slot 2 close to the inner bottom wall, and an opening and closing mechanism is provided in the discharge port 12, and the discharge port 12 is connected with an external discharge hopper, so that unqualified materials discharged from the discharge port 12 can be uniformly discharged. Once the material is processed and collected, when the material is transmitted on the conveyor belt 3, the lower end of the material is opposite to the discharge port 12 under the action of gravity and is against the baffle 15 of the closing mechanism in the discharge port 12. The conveying box 1 is symmetrically installed with telescopic cylinders 4, and the output end of each telescopic cylinder 4 extends into the sorting slot 2 and is fixedly connected with a movable plate 5, and the movable plate 5 is located on the high side of the bottom wall of the sorting slot 2. A pressure plate 7 is elastically connected to the side surface of the movable plate 5 away from the telescopic cylinder 4 through a plurality of buffer springs 6. A control mechanism is provided in the conveying box 1, and the output end of the control mechanism is connected with the input end of the opening and closing mechanism.

[0022] In this embodiment, the opening and closing mechanism includes a slide groove 13 horizontally opened on the inner wall of the discharge port 12, and a baffle 15 cooperating with the discharge port 12 is elastically connected to the groove wall of the slide groove 13 through a conductive spring 14, and the baffle 15 is slidably connected to the slide groove 13 and the discharge port 12. The control mechanism includes a placement groove 8 vertically opened in the conveying box 1, and a moving contact 9 is slidably connected in the placement groove 8. A traction line 10 is fixedly connected between the moving contact 9 and the pressure plate 7. A static contact 11 cooperating with the moving contact 9 is provided on the inner wall of the placement groove 8, and the static contact 11 is located above the moving contact 9. The moving contact 9 and the static contact 11 are electrically connected to the two ends of the conductive spring 14 and an external power supply through wires respectively.

[0023] The functional principle of this embodiment can be explained through the following operation mode: the material is transmitted on the conveyor belt 3. When the material is facing the pressure plate 7, the conveyor belt 3 stops transmitting, and the telescopic cylinder 4 pushes the movable plate 5 and the pressure plate 7 to move toward the material, so that the pressure plate 7 and the material are against each other. At this time, the buffer spring 6 is in a compressed state. The telescopic cylinder 4 keeps for a period of time and then retracts the pressure plate 7 and the movable plate 5. After that, the qualified material continues to be sent to the next process by the conveyor belt 3; and for the material with unqualified length, when the pressure plate 7 and the movable plate 5 move toward the material, since the length of the unqualified material is less than the length of the marked material, although the stroke of the movable plate 5 is a fixed value, the pressure plate 7 will continue to move under the elastic force of the buffer spring 6. The pressing plate 7 continues to move toward the material, then compared with the qualified material, when detecting the unqualified material, the movement stroke of the pressing plate 7 toward the material is greater, then the pressing plate 7 drives the moving contact 9 to move higher in the placement slot 8 through the traction line 10, so that the moving contact 9 is in contact with the static contact 11 and is connected, then the conductive spring 14 is energized, and according to the knowledge of electromagnetics, since the directions of the currents passing through the coils in the conductive spring 14 are consistent, according to the characteristic that the adjacent coils with the same current direction will generate attraction, the conductive spring 14 will shrink rapidly, thereby releasing the blockade of the baffle 15 on the discharge port 12, and the unqualified material will fall into the discharge hopper through the discharge port, thereby realizing the sorting and removal of the unqualified material.

[0024] Example 2

[0025] Reference Figure 3 The difference between this embodiment and embodiment 1 is that: the moving contact 9 and the groove wall of the placement groove 8 are sealed and slidably connected, and the sealed space formed by the upper end surface of the moving contact 9 and the placement groove 8 is the driving area, and an air guide pipe 16 is connected to the top wall of the placement groove 8, and the other end of the air guide pipe 16 extends into the sorting groove 2 and faces the upper end surface of the conveyor belt 3, and an air intake pipe 17 is connected between the upper side of the groove wall of the placement groove 8 and the outside world, and a first one-way valve and a second one-way valve are respectively installed in the air guide pipe 16 and the air intake pipe 17. The first one-way valve only allows the gas or liquid in the driving area to be discharged into the sorting groove 2 through the air guide pipe 16, and the second one-way valve only allows the external gas or liquid to enter the driving area through the air intake pipe 17.

[0026] The functional principle of this embodiment can be explained through the following operation mode: each time the telescopic cylinder 4 drives the pressure plate 7 to move, the pressure plate 7 will drive the moving contact 9 to move upward through the traction line 10 to compress the driving area, and the gas in the driving area will be quickly blown toward the material to be detected through the air guide pipe 16, thereby assisting in removing dust or moisture on the material, which is highly practical. Moreover, since the inner bottom wall of the sorting trough 2 is inclined, it is easier to gather and discharge dust and moisture without polluting the work surface.

[0027] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
