Description

Technical Field

[0001] This utility model relates to the field of sorting equipment technology, specifically to an automatic material sorting device for food processing. Background Technology

[0002] In the pet food processing industry, the requirements for product quality are increasing. The selection of material size is a basic process. The size of the material has an important impact on the palatability and digestibility of pets. If the size of the material is too large, it will cause pets to have difficulty eating, chewing and digesting, thus affecting product quality.

[0003] In the past, manual sorting was a common method for sorting materials by size in pet food processing. However, manual sorting could not keep up with the pace of large-scale production. Current methods mostly use sieves, which utilize sieves with different aperture sizes to sort materials, allowing materials smaller than the sieve aperture to pass through while retaining those larger. However, sieves are not effective at sorting irregularly shaped materials, which can get stuck in the sieve holes, causing inaccurate sorting and affecting the stability of product quality.

[0004] Therefore, this utility model proposes an automatic material sorting device for food processing to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic material sorting device for food processing, which solves the problem in the prior art that the screens are not effective at screening irregularly shaped materials, resulting in inaccurate screening and affecting the stability of product quality.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An automatic material sorting device for food processing includes a conveying device and a screening device, with the screening device positioned above the conveying device. The conveying device includes a conveyor belt, a first drive motor, and a support frame. The conveyor belt is mounted on the support frame, and the first drive motor is connected to the drive roller of the conveyor belt and fixedly connected to the support frame. Multiple support rollers are evenly connected to the support frame, and the support rollers are in contact with the bottom surface of the conveyor belt.

[0012] Furthermore, the conveyor belt is provided with side guards on both sides, the side guards are connected to the support frame, and the surface of the conveyor belt is uniformly provided with multiple anti-slip protrusions.

[0013] By adopting the above technical solution, the side guards are connected to the support frame, which can effectively prevent materials from slipping off both sides of the conveyor belt during the conveying process; multiple anti-slip protrusions are evenly distributed on the surface of the conveyor belt, which increases the friction between the material and the conveyor belt and prevents the material from slipping during the conveying process.

[0014] Furthermore, the feed end of the conveyor belt is provided with a feeding disc, which is rotatably connected to the support frame. The drive shaft of the third drive motor is coaxially connected to the feeding disc, and the third drive motor is fixedly connected to the support frame.

[0015] By adopting the above technical solution, the material entering the conveyor belt can be evenly dispersed, so that the material is evenly distributed on the conveyor belt.

[0016] Furthermore, a cleaning brush is provided at the bottom of the conveyor belt, the cleaning brush is rotatably connected to the support frame, and a cleaning box is provided at the bottom of the cleaning brush, the cleaning box being connected to the support frame.

[0017] By adopting the above technical solution, the conveyor belt can be cleaned, and the cleaned debris and dirt fall into the cleaning box below.

[0018] Furthermore, the outer side of the conveying device and the screening device is provided with a protective shell, and the protective shell is connected to an observation window and a maintenance door.

[0019] By adopting the above technical solutions, the hygiene quality of the food processing environment can be guaranteed, and the internal operation of the equipment can be observed at any time through the observation window.

[0029] like Figure 1-4 As shown, an automatic material sorting device for food processing includes a conveying device and a screening device. The screening device is positioned above the conveying device. The conveying device includes a conveyor belt 1, a first drive motor 6, and a support frame 5. The conveyor belt 1 is mounted on the support frame 5. The first drive motor 6 is connected to the drive roller of the conveyor belt 1 and is fixedly connected to the support frame 5. Multiple support rollers 7 are evenly connected to the support frame 5, and the support rollers 7 are in contact with the bottom surface of the conveyor belt 1. Side rails 2 are provided on both sides of the conveyor belt 1 and are connected to the support frame 5. Multiple anti-slip protrusions 3 are evenly distributed on the surface of the conveyor belt 1. The support rollers 7 abut against the bottom surface of the conveyor belt 1, providing auxiliary support and ensuring the stability of the conveyor belt 1 during operation. Simultaneously, the side rails 2 on both sides of the conveyor belt 1, connected to the support frame 5, effectively prevent materials from slipping off the sides of the conveyor belt 1 during conveying. The evenly distributed anti-slip protrusions 3 on the surface of the conveyor belt 1 increase the friction between the material and the conveyor belt 1, preventing material slippage during conveying. The outer side of the conveying device and the screening device is provided with a protective shell 24, and the protective shell 24 is connected with an observation window 25 and a maintenance door 26.

[0030] Furthermore, the screening device includes a vibrating screen 8 and a screening mesh 9. The vibrating screen 8 is connected above the support frame 5 by an elastic support member, which includes a spring 18 and a rubber pad 19. One end of the spring 18 is connected to the bottom of the vibrating screen 8, and the other end is connected to the support frame 5. The rubber pad 19 is connected between the spring 18 and the support frame 5. This not only supports the vibrating screen 8 but also effectively buffers the vibration generated during the operation of the vibrating screen 8, reducing the impact on other parts of the equipment. The screening mesh 9 is set inside the vibrating screen 8. A vibrating motor 10 is connected to the bottom of the vibrating screen 8. A guide plate 11 is provided inside the frame of the vibrating screen 8. The guide plate 11 is inclined and set at the lower end of the screening mesh 9. The lower end of the guide plate 11 is set at the end of the conveyor belt 1. A connecting frame 12 is slidably connected above the vibrating screen 8. The drive mechanism drives the connecting frame 12 to slide. A feeding roller 16 is rotatably connected to the connecting frame 12. A second drive motor 14 is coaxially connected to the feeding roller 16 and is fixedly connected to the connecting frame 12. The drive mechanism includes a stepper motor 17 and a lead screw 15. The stepper motor 17 and the lead screw 15 are coaxially connected. The connecting frame 12 is threadedly engaged with the lead screw 15. The lead screw 15 is rotatably connected to the vibrating screen 8. The stepper motor 17 is fixedly connected to the vibrating screen 8.

[0031] Furthermore, a material feeding end of the conveyor belt 1 is provided with a material feeding disc 20, which is rotatably connected to the support frame 5. The drive shaft of the third drive motor 21 is coaxially connected to the material feeding disc 20, and the third drive motor 21 is fixedly connected to the support frame 5. This allows the material entering the conveyor belt 1 to be evenly dispersed, ensuring that the material is evenly distributed on the conveyor belt 1.

[0032] Furthermore, a cleaning brush 22 is provided at the bottom of the conveyor belt 1. The cleaning brush 22 is rotatably connected to the support frame 5. A cleaning box 23 is provided at the bottom of the cleaning brush 22. The cleaning box 23 is connected to the support frame 5.

[0033] The working process of this utility model is as follows:

[0034] First, the vibrating motor 10 starts, driving the vibrating screen 8 to vibrate at high frequency. Under the action of vibration, the material is screened on the screening screen 9. Material with a size smaller than the mesh size of the screening screen 9 falls through the screening screen 9, while material with a size larger than the mesh size remains on the screening screen 9 for further screening. The guide plate 11, which is inclined below the screening screen 9, guides the screened material to the end of the conveyor belt 1, allowing it to fall smoothly onto the conveyor belt 1. At the same time, the stepper motor 17 connected to the vibrating screen 8 starts working, driving the lead screw 15 to rotate. Then, the connecting frame 12 is threadedly engaged with the lead screw 15, and the connecting frame 12 slides above the vibrating screen 8 along the direction of the lead screw 15. The second drive motor 14 on the connecting frame 12 starts, driving the material-shifting roller 16 to rotate, thus shifting the position of the material.

[0035] Simultaneously, the first drive motor 6 starts working, driving the drive roller of the conveyor belt 1 to rotate, which in turn drives the conveyor belt 1 to rotate. The material is conveyed forward under the drive of the conveyor belt 1. The surface of the conveyor belt 1 is provided with anti-slip protrusions 3, which increases the friction with the material and ensures that the material moves stably with the conveyor belt 1. At the same time, the side guards 2 on both sides prevent the material from slipping off the sides of the conveyor belt 1. Then, the third drive motor 21 drives the material feeding disc 20 to start rotating. The material enters the feeding end of the conveyor belt 1, and the material feeding disc 20 evenly disperses the material, making the material more evenly distributed on the conveyor belt 1, thus completing the automatic sorting of the material.

[0036] As the conveyor belt 1 continues to operate, it passes over the cleaning brush 22. The corresponding drive device drives the cleaning brush 22 to rotate, thereby cleaning the conveyor belt 1. The cleaned debris and dirt fall into the cleaning box 23 below. Throughout the operation of the equipment, the operator can observe the internal operation of the equipment at any time through the observation window 25 on the protective shell 24. If the equipment malfunctions, it can be repaired through the maintenance door 26.
