[0024] An anti-slip coating is provided on the fixing and moving block 106 to enhance the fixing effect of the fixing and moving block 106 on the bamboo chopsticks 100.

[0025] It also includes a brush plate 202; the brush plate 202 is arranged on the conveyor belt 2; the surface of the bamboo chopsticks 100 to be screened is cleaned by the brush plate 202 to prevent the bamboo chips remaining on the surface of the bamboo chopsticks 100 from affecting the detection of the visual sensor 108.

[0026] The brush plate 202 and the conveyor belt 2 are detachably connected. When the cleaning effect of the brush plate 202 decreases, the brush plate 202 is removed and replaced.

[0027] A handle is arranged on the collection box 4 for facilitating manual pulling of the collection box 4.

[0028] The working process of this batch processing and rapid self-checking and screening equipment for bamboo chopsticks is as follows: Place the present invention on the right side of the bamboo chopstick production equipment; as Figure 2 shown, the bamboo chopstick production equipment discharges the bamboo chopsticks 100 one by one at the same speed as the conveying speed of the clamping and fixing assembly. At this time, the electromagnet 201 on the left part of the conveyor belt 2 is energized to generate magnetic suction. The electromagnet 201 adsorbs the iron cylinder 10601, causing the fixed moving block 106 to be transformed into the contracted state as shown in the rightmost figure at this time. The bamboo chopsticks 100 are discharged by the bamboo chopstick production equipment and move to the clamping block 105. Stop energizing the electromagnet 201 on the left part of the conveyor belt 2, and the fixed moving block 106 is transformed into the state as shown in the leftmost figure. The two clamping and fixing assemblies on the front and rear conveyor belts cooperate with each other to clamp and fix both ends of the bamboo chopsticks 100, and the connected part at the top of the bamboo chopsticks 100 is located on the front clamping and fixing assembly. Figure 3 After the bamboo chopsticks 100 are clamped and fixed by the clamping and fixing assembly, they are conveyed by the conveyor belt 2 and conveyed from the left side of the conveyor belt 2 to the lower left. When the bamboo chopsticks 100 are conveyed past the brush plate 202, the brush plate 202 cleans the bamboo chips on its surface. During the process of the bamboo chopsticks 100 passing through the brush plate 202, the electric rotating shaft 102 rotates, driving the first driving part 103 and the parts thereon to rotate together. The clamping and fixing assembly drives the bamboo chopsticks 100 to rotate, allowing the brush plate 202 to brush the surface of the bamboo chopsticks 100. The bamboo chopsticks 100 continue to be conveyed. When they are conveyed below the visual sensor 108, the clamping and fixing assembly continues to drive the bamboo chopsticks 100 to rotate. The visual sensor 108 detects the surface condition of the bamboo chopsticks 100. If there are obvious defects on the surface of the bamboo chopsticks 100, the electromagnet 201 below the visual sensor 108 is energized to generate magnetic suction, adsorbing the iron cylinder 10601, causing the fixed moving block 106 to be transformed into the state as shown in the rightmost figure. Figure 3 Release the fixation of the bamboo chopsticks 100, and let the bamboo chopsticks 100 fall downward to the first collection area 4001.

[0029] After the bamboo chopsticks 100 are clamped and fixed by the clamping and fixing assembly, they are conveyed by the conveyor belt 2 and conveyed from the left side of the conveyor belt 2 to the lower left. When the bamboo chopsticks 100 are conveyed past the brush plate 202, the brush plate 202 cleans the bamboo chips on its surface. During the process of the bamboo chopsticks 100 passing through the brush plate 202, the electric rotating shaft 102 rotates, driving the first driving part 103 and the parts thereon to rotate together. The clamping and fixing assembly drives the bamboo chopsticks 100 to rotate, allowing the brush plate 202 to brush the surface of the bamboo chopsticks 100. The bamboo chopsticks 100 continue to be conveyed. When they are conveyed below the visual sensor 108, the clamping and fixing assembly continues to drive the bamboo chopsticks 100 to rotate. The visual sensor 108 detects the surface condition of the bamboo chopsticks 100. If there are obvious defects on the surface of the bamboo chopsticks 100, the electromagnet 201 below the visual sensor 108 is energized to generate magnetic suction, adsorbing the iron cylinder 10601, causing the fixed moving block 106 to be transformed into the state as shown in the rightmost figure. Figure 3 Release the fixation of the bamboo chopsticks 100, and let the bamboo chopsticks 100 fall downward to the first collection area 4001.

[0030] The bamboo chopsticks 100 are clamped and driven to continue to be transported. When they are transported close to the fixed plate 109, the electric shaft 102 drives the first driving member 103 and the parts thereon to rotate so that the through slot 10501 faces upward. It should be noted that the through slot 10501 is directly opposite to the gap between the bamboo chopsticks 100. When the bamboo chopsticks 100 are located directly above the fixed plate 109, the output end of the second driving member 111 is driven to move downward, so that it drives the extrusion block 112 to move downward. The extrusion block 112 passes through the through slot 10501 and is inserted into the gap at the end of the bamboo chopsticks 100. The second electric slider 110 is driven to drive the second driving member 111 and the parts thereon to move forward. It should be noted that after the extrusion block 112 is inserted into the bamboo chopsticks 100, the movable distance is set between 3mm and 7mm after being tested with bamboo chopsticks 100 that meet the specifications. This range can ensure that the bamboo chopsticks 100 are not too loose after being cut, which may cause the bamboo chopsticks 100 to break easily, and ensure that they can be easily separated during use, while at the same time, the loose connection will not affect the user experience or cause safety hazards. If the distance that the extrusion block 112 can move after being inserted into the bamboo chopsticks 100 is too short, or the extrusion block 112 is inserted into the bamboo chopsticks 100 and moves within a limited distance, after the output end of the second driving member 111 drives the extrusion block 112 to move upward, when the micro camera finds that the bamboo chopsticks 100 cannot return to their original state after being squeezed by the extrusion block 112, the electromagnet 201 under the fixed plate 109 is energized to generate a magnetic attraction, adsorb the iron cylinder 10601, and drive the fixed moving block 106 to be transformed into Figure 3 In the state shown on the right, the bamboo chopsticks 100 are released from being fixed, and fall into the second collecting area 4002. It should be noted that when the squeezing block 112 is inserted into the bamboo chopsticks 100, the burrs and debris stuck in the bamboo chopsticks 100 can be cleaned through the blowing holes 11201.

[0031] When the bamboo chopsticks 100 are transported to the area where the extrusion assembly is located, the iron cylinder 10601 is located on the side of the extrusion bar 114 away from the bamboo chopsticks 100. As the clamping and fixing assembly is being transported, the iron cylinder 10601 is gradually squeezed by the extrusion bar 114 and gradually transformed into Figure 3 The middle state shown, at this time the clamping fixing assembly can only fix the standard length of bamboo chopsticks 100, shorter than the standard length of bamboo chopsticks 100 are dropped downward to the third collection area 4003; The bamboo chopsticks 100 continue to be transported. When the bamboo chopsticks 100 are located above the fourth collecting area 4004, the iron cylinder 10601 is gradually squeezed by the squeezing strip 114 and transformed into Figure 3 In the state shown on the right, the bamboo chopsticks 100 are dropped into the fourth collecting area 4004. At this point, all the bamboo chopsticks 100 are collected by the collecting frame 4, and the screening of the bamboo chopsticks 100 is completed. Then, the clamping and fixing components are transformed into the following state: Figure 3 The state shown on the first right continues to be transmitted, and other bamboo chopsticks 100 are clamped and screened again.

[0032] According to the above work process, we can know that the present invention has the following effects: Compared with the existing screening method of manually observing the surface of the bamboo chopsticks 100 as shown in Figure 8 , the present invention clamps the bamboo chopsticks 100 through the clamping and fixing component, and drives the bamboo chopsticks 100 to pass through the vision sensor 108 on the conveyor belt 2 through the clamping and fixing component, so as to detect the surface of the bamboo chopsticks 100, realizing the efficient and accurate identification of the surface defects of the bamboo chopsticks 100, realizing the full automation and high efficiency of the detection process, and greatly improving the efficiency of the overall production process and the quality control level.

[0033] During the conveying process of the bamboo chopsticks 100 on the conveyor belt 2, through multiple automatic detection processes such as passing through the vision sensor 108 and the extrusion block 112 to detect the tightness of the connection of the bamboo chopsticks 100, it is ensured that only the bamboo chopsticks 100 that meet the quality standards and length requirements can pass the screening, effectively improving the stability and reliability of the product quality.

[0034] By arranging the vision sensor 108, the extrusion block 112 and the extrusion strip 114 in the conveying order, and making the first collection area 4001, the second collection area 4002 and the third collection area 4003 correspond to them respectively, different types of defective bamboo chopsticks 100 are collected in different areas. Finally, the size of the bamboo chopsticks 100 is detected, so that the bamboo chopsticks 100 without defective quality problems but only with non-conforming sizes can be used as defective products or as materials for splicing bamboo chopsticks, reducing waste and improving the utilization rate of raw materials.

[0035] The additional technical effects of the present invention are as follows: Among them, as shown in Figure 1 , a handle is provided on the collection box 4, which is convenient for manually pulling out the collection box 4 containing the bamboo chopsticks 100.

[0036] Although the present invention has been described with reference to the exemplary embodiments, it should be understood that the present invention is not limited to the disclosed exemplary embodiments.
