Description

Technical Field

[0001] This application relates to the field of chopsticks sorting and sorting technology, specifically to an integrated chopsticks sorting and sorting machine. Background Technology

[0002] Compared to other tableware, chopsticks are used directly in the mouth, making hygiene crucial. Especially in high-traffic areas like public canteens, a large number of chopsticks are used. To address the problems of inconsistent hygiene, high labor intensity, and low efficiency associated with traditional manual washing methods, various chopstick washing machines have emerged. However, the prolonged tumbling and friction during washing can easily lead to breakage. Therefore, before packaging, unqualified chopsticks need to be sorted, and manual sorting is prone to omissions. While sorting mechanisms are used, existing ones are complex, requiring pre-testing and subsequent sorting, necessitating high coordination between modules and increasing costs. Based on these issues, the applicant has previously applied for a chopstick defective screening device (2). (23159637U) Due to the possibility of chopsticks of different lengths during use, such as when eating hot pot, the length of serving chopsticks may be longer than that of adult chopsticks. Since this chopstick defective screening device can only be used for one type of standard chopstick at a time, either multiple screening devices are needed, taking up a lot of space, or multiple sizes of chopsticks need to be screened in batches (adjusting the spacing between the two end baffles and two sets of side belt conveyors according to the chopstick length), resulting in low work efficiency. Furthermore, both of these methods require chopsticks to be washed in batches according to length during cleaning, further reducing cleaning efficiency. Because chopsticks are prone to inconsistent tip orientation during collection and washing, direct handling can easily lead to contact with inconsistently oriented tips, causing contamination and potentially affecting the user's health. Utility Model Content

[0003] In view of this, this application provides an integrated chopsticks sorting and sorting machine to solve the technical problems of low efficiency and inconsistent orientation of chopsticks ends in existing single-specification chopsticks sorting devices, which can easily lead to safety issues during use.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A chopsticks sorting and organizing integrated machine includes a frame, and further includes two layers of chopsticks sorting devices arranged vertically. Each layer of chopsticks sorting devices has a chopsticks turning mechanism or a storage basket at its output end. The chopsticks sorting device includes a central belt conveyor mechanism inclined at the same angle on the frame and two sets of symmetrically arranged side belt conveyors. The central belt conveyor mechanism is located between the two sets of side belt conveyors. The discharge end drive wheel of the central belt conveyor mechanism and the feed end drive wheel of the side belt conveyor mechanism are coaxially arranged. A material drop channel is formed between the two sets of side belt conveyors. A chopsticks dropping hopper is provided at the material drop channel. The central conveyor belt of the central belt conveyor mechanism is provided with multiple first dividing baffles spaced apart, and the side conveyor belts of the side belt conveyor mechanism are provided with multiple second dividing baffles spaced apart. Both the first dividing baffles and the second dividing baffles extend along the width direction. In use, chopsticks of acceptable length located between two adjacent first dividing baffles are transferred to the corresponding two adjacent second dividing baffles and continue to be conveyed. Chopsticks that are shorter in length after being screened by the upper chopstick screening device fall along the corresponding chopstick dropping conveyor hopper onto the middle belt conveyor mechanism of the lower chopstick screening device. After being screened again, chopsticks that are broken and unqualified fall freely along the corresponding chopstick dropping conveyor hopper, thus completing the sorting.

[0005] Furthermore, the frame is equipped with one or two adjustable side plates for guiding the chopsticks to be transported. The adjustable side plates are located on the corresponding side of the central belt conveyor mechanism, so that the width of the chopsticks transport channel can be adjusted.

[0006] Furthermore, the spacing adjustment side plate is in the shape of a "|" flat strip or a "<" bent shape.

[0007] Furthermore, the side of the central belt conveyor is provided with a pallet flush with the conveying plane, and the spacing adjustment side plate is located above the pallet and extends to the side of the corresponding side belt conveyor.

[0008] Furthermore, the chopstick turning mechanism includes a moving channel with two parallel slots on the bottom surface of the moving channel. A chain drive mechanism is installed in the slots. The side of the moving channel has an inclined first feeding channel. As the chopsticks move with the chain drive mechanism, due to the uneven weight distribution at both ends of the chopsticks, the chopsticks with handles close to the first feeding channel will be collected along the first feeding channel, while the remaining chopsticks will be collected using the second feeding channel.

[0009] Furthermore, the drive wheels of both the center belt conveyor and the side belt conveyor are sprockets, and the center and side conveyor belts are plastic chain plates.

[0010] Furthermore, the tilt angle of the mid-position belt conveyor mechanism ranges from 30° to 60°.

[0011] Furthermore, the discharge end drive wheel of the center belt conveyor has the same specifications as the feed end drive wheel of the side belt conveyor.

[0012] Furthermore, a storage bin is provided on the frame, and the chopsticks falling along the storage bin will fall onto the middle belt conveyor mechanism of the upper chopsticks screening device.

[0013] Furthermore, a guide plate is provided between the two sets of side belt conveyor mechanisms that work together, near the discharge end. The guide plate is used to guide the screened chopsticks to the chopstick turning mechanism or into the storage basket.

[0014] Furthermore, the gap between the two sets of side belt conveyor mechanisms is adjustable.

[0015] Furthermore, the lower edges of both the storage bin and the chopstick conveyor hopper are equipped with flexible lip plates that fit into the corresponding middle conveyor belt.

[0016] As can be seen from the above technical solution, the advantages of this utility model are: 1. In this application, a two-layer chopsticks sorting device is used to sort chopsticks of two different lengths in one go, which makes the work efficient and allows chopsticks to be cleaned in two different lengths at the same time, which also improves the cleaning efficiency of chopsticks. 2. In this application, a method is provided in which chopsticks are carried out by a central belt conveyor mechanism to be laid out and transported in sequence for sorting. The sorting is carried out by the difference between the distance between two sets of side belt conveyors and the length of the chopsticks. The method has high work efficiency, long sorting station, high sorting accuracy, and simple structure.

[0017] 3. The central belt conveyor and the side belt conveyor in this application are inclined, and gravity is used to make the chopsticks always distributed along the width of the conveyor belt during the conveying process, so that the chopsticks are neatly arranged and the sorting accuracy is high.

[0018] 4. Both the central conveyor belt and the side conveyor belt in this application are equipped with partition baffles, which can accurately drive the chopsticks to be transported continuously and reliably.

[0019] 5. In this application, a chopstick turning mechanism is used to reorganize the sorted chopsticks according to their orientation, so that the large and small ends of the collected chopsticks are in the same direction, which is hygienic and safe to use, and the sorting efficiency is high.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and their descriptions are used to explain this application, but are not intended to limit it.

[0033] refer to Figures 1 to 10 ,like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a chopsticks sorting and sorting integrated machine, including a frame 1 and two layers of chopsticks sorting devices arranged vertically on the frame 1. The upper chopsticks sorting device is used for sorting long chopsticks, and the lower chopsticks sorting device is used for sorting short chopsticks. It can simultaneously sort chopsticks 100 of mixed lengths, resulting in high work efficiency and a small footprint. Each layer of chopsticks sorting device has a chopsticks turning mechanism 10 or a storage basket at its output end. With the chopsticks turning mechanism 10 installed, the sorted chopsticks can be turned around and then stored. The automatic chopsticks can be turned around and sorted automatically. When the storage basket is set up, the chopsticks (100) after screening can be directly stored. Alternatively, a guide channel can be set between the chopstick screening device and the storage basket to adapt to the placement of the storage basket. A chopstick conveying hopper 9 is set between the two layers of chopstick screening devices to realize the linkage of the two layers of chopstick screening devices. This facilitates the synchronous screening of two specifications of chopsticks 100, resulting in high work efficiency. Compared with the double-parallel setting device, it occupies less space and can wash two length specifications of chopsticks 100 at the same time, which will also improve the washing efficiency of chopsticks 100.

[0034] In this application, the chopsticks sorting device includes a central belt conveyor 2 inclined at the same angle on a frame 1 and two sets of symmetrically arranged side belt conveyors 4. The central belt conveyor 2 is located between the two sets of side belt conveyors 4. The discharge end drive wheel of the central belt conveyor 2 is coaxially arranged with the inlet end drive wheel of the side belt conveyor 4. A material drop channel is formed between the two sets of side belt conveyors 4. A chopsticks dropping hopper 9 is provided at the material drop channel. Multiple first dividing baffles 22 are provided on the central conveyor belt 21 of the central belt conveyor 2 at intervals. Multiple second dividing baffles 42 are provided on the side conveyor belts 41 of the side belt conveyors 4 at intervals. Both the first dividing baffles 22 and the second dividing baffles 42 extend along the width direction. The arrangement of the first dividing baffles 22 and the second dividing baffles 42 can prevent the chopsticks 100 from automatically slipping during the lifting process. The inclined arrangement of the conveyor device can prevent the chopsticks 100 from automatically slipping during the lifting process. All chopsticks 100 are arranged parallel to each other relative to the dividing baffles, so that the chopsticks 100 are perpendicular to the conveying direction of the central conveyor belt 21 during the conveying process. By adjusting the position, it is ensured that chopsticks 100 of qualified length can be conveyed to the side belt conveyor mechanism 4, reducing the possibility of chopsticks 100 being missorted. The width of the central conveyor belt 21 of the central belt conveyor mechanism 2 is smaller than the length of the chopsticks 100 to be screened in the current layer, so that the two ends of the chopsticks 100 extend out of the central conveyor belt 21 during the conveying process. The gap between the two sets of side belt conveyor mechanisms 4 is smaller than the length of the chopsticks 100 to be screened in the current layer, ensuring that the two ends of the chopsticks 100 in the current layer can be placed on the side conveyor belt 41 of the corresponding side belt conveyor mechanism 4. When the chopsticks 100 are conveyed by the two sets of side belt conveyor mechanisms 4, they are suspended in the middle. Chopsticks 100 of unqualified length will fall along the channel between the two sets of side belt conveyor mechanisms 4.

[0035] In this application, the driving mechanisms of the central belt conveyor 2 and the side belt conveyor 4 can be driven independently by corresponding driving mechanisms 6 or driven by the same driving mechanism 6. When different driving mechanisms 6 are used, the corresponding driving mechanism 6 is poweredly connected to the drive wheel of the central belt conveyor 2, and the drive wheel is located near the feeding end of the central belt conveyor 2. The corresponding driving mechanism 6 is poweredly connected to the drive wheel of the side belt conveyor 4, and the drive wheel is located near the discharging end of the side belt conveyor 4. The drive wheels of the two sets of side belt conveyors 4 are coaxially arranged through corresponding linkage shafts 5. When the same driving mechanism 6 is used, the transmission wheel at the discharging end of the central belt conveyor 2 and the drive wheel at the side belt conveyor 4 are connected to the drive wheel of the side belt conveyor 4. The feed end drive wheel of the 4 is coaxially set through the corresponding linkage shaft 5. The driven wheels of the two sets of side belt conveyor mechanisms 4 are coaxially set through the corresponding linkage shaft 5. The drive mechanism 6 is poweredly connected to the feed end drive wheel or the corresponding linkage shaft 5 of the middle belt conveyor mechanism 2. The same drive mechanism 6 is used for driving, so that the middle belt conveyor mechanism 2 and the side belt conveyor mechanism 4 have high synchronization. The drive wheel of the middle belt conveyor mechanism 2 and the drive wheel of the side belt conveyor mechanism 4 have the same specifications. Since the conveying surfaces of the middle belt conveyor mechanism 2 and the side belt conveyor mechanism 4 are located on the same plane, the chopsticks 100 are transferred smoothly from the middle belt conveyor mechanism 2 to the side belt conveyor mechanism 4, so that the screening reliability is high.

[0036] In this application, a storage bin 3 is provided on the frame 1, and the chopsticks 100 falling along the storage bin 3 will fall onto the middle belt conveyor mechanism 2 of the upper chopstick screening device.

[0037] Specifically, a gap matching the diameter of the chopsticks 100 is left between the lower surface of the storage bin 3 and the upper surface of the intermediate conveyor belt 21 of the intermediate belt conveyor mechanism 2. This gap ensures that the first dividing baffle 22 can pass through while the chopsticks 100 cannot, that is, the height of the first dividing baffle 22 is less than the width of the chopsticks 100. When the intermediate conveyor belt 21 moves, it will pick up several chopsticks 100 when passing the first dividing baffle 22 of the storage bin 3, and it can ensure that only one layer of chopsticks 100 is laid on the intermediate conveyor belt 21 during the conveying process, avoiding the defect of the upper layer being unable to be sorted due to stacking, so as to achieve a high sorting accuracy. Preferably, the storage box 3 includes a rear baffle perpendicular to the central conveyor belt 21 and side baffles connected to both sides of the rear baffle. The side baffles are connected to the frame 1. A storage cavity is formed between the rear baffle, the side baffles and the central conveyor belt 21. The gap between the storage box 3 and the central conveyor belt 21 is also the gap between the rear baffle and the upper conveying surface of the central conveyor belt 21. When the central conveyor belt 21 moves, it will drive the chopsticks 100 located in the storage cavity to move upward. By using the inclined setting of the central conveyor belt 21, the chopsticks 100 exceeding the corresponding height will automatically fall into the storage cavity, so that only one layer of chopsticks 100 remains on the central conveyor belt 21, making the screening reliable.

[0038] In this application, the frame 1 is provided with one or two spacing adjustment side plates 11 for guiding the conveying of chopsticks 100. The spacing adjustment side plates 11 are located on the corresponding side of the central belt conveyor 2 and extend to the side of the corresponding side belt conveyor 4. The one-sided spacing adjustment side plate 11, the frame and the central belt conveyor 2 cooperate to form a U-shaped chopstick conveying channel, or the two-sided spacing adjustment side plates 11 and the central belt conveyor 2 cooperate to prevent the chopsticks 100 from falling off during the movement along the chopstick conveying channel. The setting of the spacing adjustment side plates 11 makes... The width of the chopstick conveying channel is adjustable to accommodate chopsticks 100 of various lengths. The spacing adjustment side plate 11 abuts against the corresponding ends of the chopsticks 100 to automatically guide and align the corresponding ends of the chopsticks 100. When the width of the side belt conveyor 4 is large, the length of the corresponding end of the chopsticks 100 resting on the side belt conveyor 4 can be determined by the guidance of the spacing adjustment side plate 11, ensuring that the other end of the chopsticks 100 of the correct length can be reliably resting on the other side belt conveyor 4.

[0039] like Figure 2 As shown, the spacing adjustment side plate 11 is in the shape of a "|" flat strip or a "<" bent shape.

[0040] When the width of the storage box 3 matches the length of the chopsticks 100, the spacing adjustment side plate 11 is in the shape of a "|" flat strip and one end is connected to the corresponding side baffle of the storage box 3 to form an extension of the side baffle, ensuring that the chopsticks 100 will not move along the width direction during the conveying process along the chopsticks conveying channel.

[0041] When the width of the storage bin 3 is greater than the length of the chopsticks 100, or when the chopsticks conveyed to the storage bin 3 by the upper chopstick conveying device 40 are off-center, the spacing adjustment side plate 11 is bent into a "<" shape, and the guide slope section 113 of the spacing adjustment side plate 11 is located on the side of the central belt conveyor 2. When using a single-sided spacing adjustment side plate 11, the position of the chopsticks 100 on the central belt conveyor 2 is adjusted and one end of the chopsticks 100 is aligned; when using a double-sided spacing adjustment side plate 11, the position of the chopsticks 100 on the central belt conveyor 2 is adjusted and one end of the chopsticks 100 is aligned. At the same time, the other end of the chopsticks 100 of the corresponding length is made to abut against the other spacing adjustment side plate 11. By aligning one end of all the chopsticks 100 before screening, it is ensured that when all the chopsticks 100 move to the side belt conveyor 4, one end can be placed on the corresponding side belt conveyor 4. Screening is carried out by using the length difference. The other end of the chopsticks 100 with the correct length can be placed on the other side belt conveyor 4, while the other end of the chopsticks 100 with the incorrect length cannot be placed on the other side belt conveyor 4 and will fall along the channel between the two sets of side belt conveyors 4.

[0042] When the structure requires it, the gap between the two sets of side belt conveyor mechanisms 4 can also be adjusted. The gap between the two sets of side belt conveyor mechanisms 4 can be adjusted according to the gap between the two sets of side belt conveyor mechanisms 4, which can be used to screen chopsticks 100 of various lengths. When it is necessary to use chopsticks 100 of a certain length, the usage requirements can be met by adjusting the gap between the two side plates 11 and the gap between the two sets of side belt conveyor mechanisms 4.

[0043] Specifically, such as Figure 8 As shown, the spacing adjustment side plate 11 has an ear plate 111 extending along the width direction. The ear plate 111 has a slot 112, and a corresponding bolt 30 passes through the slot 112 and connects to the frame 1. When adjustment is needed, loosen the bolt 30, move the spacing adjustment side plate 11 to the corresponding position, and then tighten the bolt 30. The position of the spacing adjustment side plate 11 is locked by the pressure of the bolt 30. Figure 9 As shown, the drive wheel of the side belt conveyor 4 is slidably mounted on the linkage shaft 5. The corresponding bolt 30 passes through the rim of the drive wheel and is connected to the corresponding screw hole 51 on the linkage shaft 5. When adjustment is required, the bolt 30 is loosened and the drive wheel is moved. After it is moved into place, the bolt 30 is connected to the corresponding screw hole 51. The drive wheel and the linkage shaft 5 are rotated and limited by a key structure.

[0044] In this application, the gap between the two sets of side belt conveyor mechanisms 4 of the upper chopsticks screening device is greater than the length of the chopsticks 100 screened by the lower chopsticks screening device, ensuring that shorter chopsticks 100 can be reliably filtered to the lower chopsticks screening device, thus making the reliability of screening chopsticks 100 according to length high.

[0045] In this application, in order to prevent the chopsticks 100 from accidentally falling during the lifting process of the middle belt conveyor mechanism 2, a tray 12 flush with its conveying plane is provided on the side of the middle belt conveyor mechanism 2, and the spacing adjustment side plate 11 is located above the tray 12.

[0046] In this application, such as Figure 10 As shown, in order to ensure that the material falling from the material drop channel can reliably enter the drop chopstick conveying hopper 9, the drop chopstick conveying hopper 9 has an inclined guide edge 91 inserted between two straight sections of the side conveyor belt 41. The falling material will reliably enter the drop chopstick conveying hopper 9 along the guide edge 91, avoiding the material from accidentally entering the side belt conveyor mechanism 4 and affecting its operation.

[0047] In this application, such as Figure 1 , Figure 2 and Figure 4As shown, when the chopstick turning mechanism 10 is set independently, a guide plate 7 is provided between the two sets of side belt conveyor mechanisms 4 that work together, near the discharge end. The outer end of the guide plate 7 extends to the corresponding chopstick turning mechanism 10 or the storage basket, and is used to open and guide the screened chopsticks 100 to the chopstick turning mechanism 10 or the storage basket. The inner end of the guide plate 7 extends to the corresponding chopstick dropping conveyor hopper 9, so that chopsticks 10 with unqualified length can reliably enter the chopstick dropping conveyor hopper 9.

[0048] The chopstick turning mechanism 10 includes a moving channel 101. Two parallel slots 102 are provided on the bottom surface of the moving channel 101. A chain drive mechanism 103 is installed within each slot 102. The concave shape of the chain links of the chain drive mechanism 103 forms a groove that mates with the chopsticks 100, thereby driving the chopsticks 100 to move with the chain drive mechanism 103. One side of the moving channel 101 has an inclined first feeding channel 104. The chopsticks 100 move along with the chain drive mechanism 103. Because the weight of the two ends of the chopsticks 100 is uneven, when the chopsticks 100 whose handles are close to the first material conveying channel 104 move to the first material conveying channel 104, the heavier end of the handle of the corresponding chopstick 100 is pressed down using the "seesaw" principle, so that the corresponding chopsticks 100 are collected along the first material conveying channel 104. The remaining chopsticks 100 are collected using the second material conveying channel 105, which is located on the other side of the moving channel 101 or at the discharge end.

[0049] like Figure 5 and Figure 6 As shown, when the chopstick turning mechanism 10 is linked with the side belt conveyor 4, the drive sprocket of the chain drive mechanism 103 of the chopstick turning mechanism 10 is connected to the linkage shaft 5 at the output end of the side belt conveyor 4, and one end of the moving channel 101 extends to the space between the two side belt conveyors 4.

[0050] In this application, the drive wheels of the central belt conveyor 2 and the side belt conveyor 4 are preferably sprockets. Compared with belt conveying, the sprockets make the operation of the central conveyor belt 21 and the side conveyor belt 41 reliable and prevent slippage, thus ensuring the reliable conveying of chopsticks 100. The central conveyor belt 21 and the side conveyor belt 41 are made of plastic chain plates or stainless steel chain plates.

[0051] In this application, the preferred tilt angle of the center belt conveyor 2 and the side belt conveyor 4 is 30° to 60°.

[0052] In actual use, the optimal tilt angle of the middle belt conveyor 2 is 45°, and the chopsticks 100 can automatically adjust and align themselves during the climbing conveying process by utilizing their own weight.

[0053] Preferably, in this application, the discharge end drive wheel of the center belt conveyor 2 and the feed end drive wheel of the side belt conveyor 4 have the same specifications.

[0054] In the embodiments of this application, multiple first partition baffles 22 are evenly distributed along annular intervals on the central conveyor belt 21, and multiple second partition baffles 42 are evenly distributed along annular intervals on the side conveyor belt 41. During the conveying process, chopsticks 100 located between two adjacent first partition baffles 22 can be transferred to the corresponding two adjacent second partition baffles 42. The distance between two adjacent first partition baffles 22 is the same as the distance between two adjacent second partition baffles 42, ensuring that chopsticks 100 located between two adjacent first partition baffles 22 can be completely transferred to the corresponding two adjacent second partition baffles 42, avoiding the situation where the second partition baffles 42 lift up the chopsticks 100.

[0055] In this application, the height of the second dividing baffle 42 is at least 1 cm higher than the width of the chopsticks 100. Preferably, the height of the second dividing baffle 42 is 2.5 cm.

[0056] In order to prevent chopsticks 100 from falling along the gap between the storage box 3 / drop chopstick conveying hopper 9 and the corresponding middle conveyor belt 21, the height of the first partition baffle 22 is less than the thickness of chopsticks 100, so as to ensure that chopsticks 100 can be lifted during the operation of the middle conveyor belt 21 but will not slip along the gap.

[0057] When the height of the first dividing baffle 22 is equal to or slightly greater than the thickness of the chopsticks 100, the height of the first dividing baffle 22 is related to the angle of the intermediate belt conveyor mechanism 2. The chopsticks 100 being lifted can be distributed in a single layer. To prevent the chopsticks 100 from falling along the gap between the storage box 3 / drop chopstick conveying hopper 9 and the corresponding intermediate conveyor belt 21, the lower edges of the storage box 3 and the drop chopstick conveying hopper 9 are provided with flexible lip plates 200 that fit against the corresponding intermediate conveyor belt 21. During the operation of the intermediate conveyor belt 21, when the first dividing baffle 22 reaches the flexible lip plate 200, it will lift the side of the flexible lip plate 200 that abuts against the conveying surface. After passing the flexible lip plate 200, the side of the flexible lip plate 200 that abuts against the conveying surface will automatically fall down and fit against the conveying surface of the middle conveyor belt 21, preventing the chopsticks 100 from falling along the gap. The repeated contact and separation between the flexible lip plate 200 and the multiple spaced first partition baffles 22 will generate vibration, which will cause the chopsticks 100 entering the storage box 3 / chopstick conveying hopper 9 to be vibrated. During the vibration, the chopsticks 100 are straightened, that is, the chopsticks 100 are quickly adjusted to the same direction as the width direction of the middle conveyor belt 21, which has a sorting effect on the chopsticks 100, so that the chopsticks 100 can be conveyed in a short time, making the chopstick conveying efficiency high and stable.

[0058] In this application, the commonly used chopsticks 100 have length specifications of 240mm, 240.5mm, 270mm, and 270.2mm. The upper chopstick screening device is used to screen chopsticks with length specifications of 270mm and 270.2mm, and the lower chopstick screening device is used to screen chopsticks with length specifications of 240mm and 240.5mm.

[0059] Specifically, the preferred spacing between the two adjustable side plates 11 of the upper chopsticks screening device is 271mm or 272mm. A spacing of 271mm is used for conveying and screening chopsticks 100 with a length of 270mm, and a spacing of 272mm is used for conveying and screening chopsticks 100 with a length of 270.2mm. The spacing between the two adjustable side plates 11 is usually set to be 1-2mm larger than the length of the chopsticks 100 to avoid jamming due to uneven processing precision of the chopsticks 100, and to guide and limit the movement of the chopsticks 100; the two adjustable side plates 11 of the lower chopsticks screening device... The preferred spacing between the two adjustable side plates 11 is 241mm or 242mm. When the spacing between the two adjustable side plates 11 is 241mm, it is used for conveying and screening chopsticks 100 with a length of 240mm. When the spacing between the two adjustable side plates 11 is 241mm, it is used for conveying and screening chopsticks 100 with a length of 240mm. When the spacing between the two adjustable side plates 11 is 242mm, it is used for conveying and screening chopsticks 100 with a length of 240mm or 5mm. The spacing between the two adjustable side plates 11 is usually set to be 1-2mm larger than the length of the chopsticks 100 to avoid the chopsticks 100 getting stuck due to uneven processing precision, and to guide and limit the movement of the chopsticks 100.

[0060] In this application, the spacing between the two sets of side belt conveyor mechanisms 4 of the lower chopsticks screening device is preferably 230 mm, for screening chopsticks 100 with lengths of 240 mm and 240.5 mm; the spacing between the two sets of side belt conveyor mechanisms 4 of the upper chopsticks screening device is preferably 260 mm, for screening chopsticks 100 with lengths of 270 mm and 270.2 mm.

[0061] In the embodiments of this application, a receiving basket can be placed below the chopstick conveying hopper 9 located at the material discharge channel of the lower chopstick screening device to facilitate the collection of broken chopsticks 100.

[0062] In use, the chopsticks 100 located in the storage bin 3 fall onto the central belt conveyor 2 of the upper chopsticks sorting device. The central belt conveyor 2 drives the continuous transport of qualified chopsticks 100 located between two adjacent first dividing baffles 22. When the chopsticks 100 move to the tail of the central belt conveyor 2, the two ends of the qualified chopsticks 100 rest on the two sets of side belt conveyors 4 of the upper chopsticks sorting device. The side belt conveyors 4 drive the chopsticks 100 to continue forward until the chopsticks 100 are transported to the corresponding chopstick turning mechanism 10 for sorting. Because there is an opening between the two sets of side belt conveyors 4, the chopsticks that are not long enough will have their ends... Chopsticks 100 that cannot be mounted on the upper side belt conveyor 4 fall along the corresponding chopstick dropping hopper 9 to the middle belt conveyor 2 of the lower chopstick screening device. Similarly, the chopsticks 100 that fall onto the middle belt conveyor 2 of the lower chopstick screening device are re-screened and sorted. Chopsticks 100 that are broken and unqualified will fall freely along the corresponding chopstick dropping hopper 9 into the collection basket, thus achieving sorting. Using the above process, the sorting and packaging process does not require human intervention, is clean and hygienic, and the quality is controllable. Moreover, this application sorts and sorts by the length of the chopsticks in conjunction with the mechanical structure, which is highly automated, but the electrical control structure is simple, thus making the structure and working principle of this application simple.

[0063] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to the embodiments of this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
