Description

Technical Field

[0001] This utility model relates to the field of food safety testing technology, and more specifically, to a foreign object removal mechanism. Background Technology

[0002] In the food processing industry, foreign object contamination has always been a key issue threatening food safety and product quality. During the planting, harvesting, transportation and storage of food raw materials, various foreign objects may be mixed in. During the processing, metal impurities generated by equipment wear and tear, dust and fibers in the operating environment may also enter the food. If they are not removed in time, they will not only harm consumers' health and cause food safety incidents, but also seriously affect the brand reputation of enterprises, and even lead to large-scale product recalls and economic losses.

[0003] However, in the process of removing foreign objects from food raw materials, existing technologies usually require workers to spread the materials evenly in order to observe the impurities. However, this greatly increases the labor intensity of workers, and the distribution of materials by workers is somewhat uneven. Therefore, a foreign object removal mechanism has been proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when removing foreign objects from food raw materials, workers usually need to spread the materials evenly in order to observe the impurities in the materials. However, this greatly increases the labor intensity of workers, and there is a certain problem of uneven distribution when workers spread the materials.

[0005] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a foreign object removal mechanism, comprising a device body. A feeding funnel is fixedly connected to the left side of the device body, and two partition plates are fixedly connected inside the feeding funnel. A vibrator is fixedly connected to the lower surface of the feeding funnel. A conveyor belt is installed inside the device body. A second motor is fixedly connected to one end of the device body, and a lead screw is fixedly connected to the output end of the second motor via a coupling. Two circumferentially distributed racks are installed inside the device body. A limiting post is fixedly connected to the inner top wall of the device body, and gears are rotatably connected to the outer surface of the limiting post. The gears mesh with the surfaces of the two racks. A linearly arranged material distribution plate is fixedly connected to the lower surface of each rack. One rack is sleeved on the outer surface of the lead screw. A sliding rod is fixedly connected inside the device body, and the outer surface of the sliding rod is slidably connected to the interior of the other rack. A debris removal mechanism is installed on the right side of the device body.

[0006] As a preferred technical solution of this application, the impurity removal mechanism includes a support frame, a negative pressure pump is fixedly connected to the upper surface of the support frame, a camera is fixedly connected to the middle position of the lower surface of the support frame, and two LED beads are fixedly connected to the support frame near the camera.

[0007] As a preferred technical solution of this application, a first motor is fixedly connected to the front of the support frame, and a threaded rod is fixedly connected to the output end of the first motor through a coupling.

[0008] As a preferred technical solution of this application, the outer surface of the threaded rod is threadedly connected to a fixing block, and the outer surface of the fixing block is slidably connected to the inside of the support frame.

[0009] As a preferred technical solution of this application, an electric telescopic rod is fixedly connected to the lower surface of the fixed block, and a fixed plate is fixedly connected to the output end of the electric telescopic rod.

[0010] As a preferred technical solution of this application, a suction device is fixedly connected to the lower surface of the fixed plate, and a corrugated pipe is fixedly connected to the upper surface of the fixed plate near the suction device.

[0011] As a preferred technical solution of this application, a material pipe is fixedly connected to the end of the corrugated pipe away from the fixed plate, and the end of the material pipe away from the corrugated pipe is fixedly connected to the surface of the negative pressure pump.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. In the solution of this application: during use, the material is initially dispersed by the built-in partition plate in the feeding hopper, and the vibrator accelerates the material to slide down. At the same time, the screw drives the rack to swing back and forth in the front and back direction and meshes with the gear to drive another rack to move, so that the two groups of feeding plates move back and forth synchronously, and the material on the conveyor belt is dispersed a second time, making the material more evenly dispersed and greatly reducing the labor intensity of workers.

[0015] 2. In the solution of this application: during use, the camera and external controller identify and lock the location of the impurities. Then, the first motor drives the threaded rod to move the fixed block back and forth, so that the suction device moves above the path of the impurities. When the material reaches directly below, the electric telescopic rod is activated to drive the suction device to move up and down, and cooperates with the negative pressure pump to suck up the impurities, so as to remove impurities at any position on the conveyor belt, improve the impurity removal accuracy and flexibility.

The partition plates 5 initially disperse the material falling into the feeding funnel 10. A vibrator 11 is fixedly connected to the lower surface of the feeding funnel 10. The vibrator 11 causes the feeding funnel 10 to vibrate, which causes the material inside the feeding funnel 10 to slide downwards. A conveyor belt 12 is installed inside the device body 1. A second motor 8 is fixedly connected to one end of the device body 1. The output end of the second motor 8 is fixedly connected to a lead screw 21 through a coupling. The second motor 8 drives the lead screw 21 to rotate. Two... The device body 1 has a rack 22 arranged in a circular pattern. A limiting post 6 is fixedly connected to the inner top wall of the device body 1. A gear 23 is rotatably connected to the outer surface of the limiting post 6. The gear 23 meshes with the surfaces of the two racks 22. The limiting post 6 limits the position of the gear 23, so that the gear 23 meshes with the two racks 22 and the two racks 22 move synchronously. A material distribution plate 9 arranged in a linear pattern is fixedly connected to the lower surface of each rack 22. One rack 22 is sleeved on the outer surface of the lead screw 21. The lead screw 21 drives one rack 22 to move back and forth in the front and back directions. A slide rod 24 is fixedly connected inside the device body 1. The outer surface of the slide rod 24 is slidably connected to the inside of the other rack 22. A cleaning mechanism is provided on the right side of the device body 1.

[0027] Furthermore, such as Figure 3 , Figure 4 As shown, the impurity removal mechanism includes a support frame 2. A negative pressure pump 4 is fixedly connected to the upper surface of the support frame 2. A camera 19 is fixedly connected to the middle position of the lower surface of the support frame 2. Two LED beads 20 are fixedly connected to the support frame 2 near the camera 19. The negative pressure pump 4 is used to generate negative pressure inside the material pipe 25 to facilitate the suction of impurity materials.

[0028] Furthermore, such as Figure 3 , Figure 4 As shown, a first motor 3 is fixedly connected to the front of the support frame 2. The output end of the first motor 3 is fixedly connected to a threaded rod 15 through a coupling. The first motor 3 drives the threaded rod 15 to rotate.

[0029] Furthermore, such as Figure 3 , Figure 4 As shown, a fixing block 13 is threadedly connected to the outer surface of the threaded rod 15. The outer surface of the fixing block 13 is slidably connected to the inside of the support frame 2. The threaded rod 15 and the fixing block 13 are driven by threaded transmission, so that the fixing block 13 can move back and forth.

[0030] Furthermore, such as Figure 3 , Figure 4As shown, an electric telescopic rod 14 is fixedly connected to the lower surface of the fixed block 13, and a fixed plate 16 is fixedly connected to the output end of the electric telescopic rod 14. The electric telescopic rod 14 drives the fixed plate 16 and the storage box 7 to move up and down.

[0031] Furthermore, such as Figure 3 , Figure 4 As shown, a suction device 17 is fixedly connected to the lower surface of the fixed plate 16, and a corrugated pipe 18 is fixedly connected to the upper surface of the fixed plate 16 near the suction device 17. The suction device 17 is used to suck up impurities.

[0032] Furthermore, such as Figure 3 , Figure 4 As shown, the end of the corrugated pipe 18 away from the fixed plate 16 is fixedly connected to the material pipe 25, and the end of the material pipe 25 away from the corrugated pipe 18 is fixedly connected to the surface of the negative pressure pump 4. The corrugated pipe 18 serves to connect the feeder 17 and the material pipe 25.

[0033] Furthermore, such as Figure 2 , Figure 4 As shown, a storage box 7 is fixedly connected to the back of the device body 1, and the output end of the negative pressure pump 4 is fixedly connected to the upper surface of the storage box 7. The storage box 7 is used to store impurity materials.

[0034] The foreign object removal mechanism provided by this utility model is used as follows: First, the material is fed into the feeding hopper 10. Then, the vibrator 11 is started, causing the feeding hopper 10 to vibrate. This causes the material inside the feeding hopper 10 to slide along the inclined surface of the bottom of the feeding hopper 10 onto the surface of the conveyor belt 12. The material is then divided by the separator 5, ensuring that it is evenly distributed on the surface of the conveyor belt 12. Next, the conveyor belt 12 is started, moving the material to the right. At this time, the second motor 8 is started, causing the second motor to... The machine 8 drives the lead screw 21 to rotate, causing the lead screw 21 to drive the rack 22 to move back and forth in the front and back direction, which in turn drives the distribution plate 9 to move back and forth in the front and back direction. The distribution plate 9 further disperses the material on the surface of the conveyor belt 12, making the material more evenly dispersed. At the same time, the rack 22 meshes with the surface of the gear 23, causing the gear 23 to rotate. The gear 23 meshes with another rack 22, which slides on the surface of the slide bar 24 and drives the distribution plate 9 at its bottom to move back and forth, simultaneously dispersing the material.

[0035] The dispersed material moves to the right, and the image captured by the camera 19 becomes clearer under the illumination of the LED 20. The camera 19 transmits the captured information to the external controller, which analyzes the location of the impurities and controls the start of the first motor 3. The first motor 3 drives the threaded rod 15 to rotate. The threaded rod 15 and the fixed block 13 are threadedly driven, moving the fixed block 13 to the path that the impurities are going to take. When the impurities reach directly below the suction device 17, the electric telescopic rod 14 is activated. The electric telescopic rod 14 drives the fixed plate 16 and the suction device 17 to move downward, so that the suction device 17 covers the impurities. At this time, the negative pressure pump 4 is activated. The negative pressure pump 4 creates negative pressure inside the material pipe 25, the bellows 18 and the suction device 17, sucking out the material and passing it into the storage box 7, thus removing impurities from the material.
