Description

Technical Field

[0001] This application relates to the technical field of chopstick sorting, and particularly relates to a defective chopstick screening device. Background Art

[0002] Compared with other tableware, chopsticks are used in a direct-to-mouth manner, so the hygiene of using chopsticks is of great significance. Especially in places with a large number of diners such as public canteens, a large number of chopsticks are used. To solve the problems of difficult hygiene control, high manual work intensity, and low work efficiency caused by traditional manual cleaning methods, various chopstick cleaning machines have emerged. However, during the cleaning process, chopsticks need to be tumbled and rubbed for a long time, and broken chopsticks are likely to be produced during the cleaning process. Therefore, after cleaning, the chopsticks need to be sorted to remove unqualified chopsticks before packaging. Manual sorting is very prone to missed inspections, and sorting mechanisms are also used for sorting. However, the existing sorting mechanisms have complex structures. Usually, a detection mechanism is required for detection first, and then a sorting mechanism is used for sorting. Each module requires a high degree of cooperation during the working process, which increases the cost of the device. Summary of the Utility Model

[0003] In view of this, this application provides a defective chopstick screening device to solve the technical problems of the existing device with complex structure and high cost.

[0004] To achieve the above object, the present utility model provides the following technical solutions:

[0005] A defective chopstick screening device includes a frame, a middle-position belt conveyor mechanism and two groups of side-position belt conveyor mechanisms symmetrically arranged on the frame at the same angle and inclined. The inclination angle range of the middle-position belt conveyor mechanism is 30° to 60°. The middle-position belt conveyor mechanism is located between the two groups of side-position belt conveyor mechanisms. The driving wheel at the discharge end of the middle-position belt conveyor mechanism is coaxially arranged with the driving wheel at the feed end of the side-position belt conveyor mechanism. A plurality of first partition baffles are arranged at intervals on the middle-position conveyor belt of the middle-position belt conveyor mechanism, and a plurality of second partition baffles are arranged at intervals on the side-position conveyor belt of the side-position belt conveyor mechanism. Two end baffles for guiding the chopstick conveying are arranged on the frame. The chopsticks located between two adjacent first partition baffles conveyed by the middle-position conveyor belt are transferred to between two corresponding adjacent second partition baffles on the side-position conveyor belt and then continue to be conveyed. The chopsticks with unqualified lengths fall freely between the two groups of side-position belt conveyor mechanisms to achieve sorting.

[0006] Furthermore, a chopstick packaging machine is arranged at the discharge end of the side-position belt conveyor mechanism. The qualified chopsticks conveyed by the side-position belt conveyor mechanism will fall into the hopper of the chopstick packaging machine.

[0007] Furthermore, the driving wheels of the middle belt-type conveying mechanism and the side belt-type conveying mechanism are both sprocket wheels, and the middle conveyor belt and the side conveyor belt are plastic chain plates.

[0008] Furthermore, the inclination angle of the middle belt-type conveying mechanism is 45°.

[0009] Furthermore, a guide plate near the discharge end is provided between the two groups of side belt-type conveying mechanisms, and the lower end of the guide plate extends above the hopper of the chopstick packaging machine.

[0010] Furthermore, a defective product receiving funnel is provided between the two groups of side belt-type conveying mechanisms.

[0011] Furthermore, the driving wheel at the discharge end of the middle belt-type conveying mechanism and the driving wheel at the feeding end of the side belt-type conveying mechanism are coaxially arranged through a linkage shaft, and the driving wheel at the discharge end of the middle belt-type conveying mechanism and the driving wheel at the feeding end of the side belt-type conveying mechanism have the same specifications.

[0012] Furthermore, a storage box is provided on the frame, and the chopsticks falling from the storage box will fall onto the middle belt-type conveying mechanism.

[0013] Furthermore, the distance between the two end baffle plates is adjustable.

[0014] Furthermore, both the first partition baffle and the second partition baffle extend along the width direction of the middle conveyor belt.

[0016] 1. In this application, the middle belt-type conveying mechanism is provided to drive the chopsticks to be sequentially laid flat for conveying and waiting for sorting. The sorting is carried out by using the length difference between the distance between the two groups of side belt-type conveying mechanisms and the length of the chopsticks. The working efficiency is high, the sorting station is long, the sorting accuracy is high, and the structure is simple.

Detailed implementation manners

[0023] To make the objectives, technical solutions and advantages of this application more clearly understood, the following further elaborates on this application in conjunction with the implementation manners and the drawings. Herein, the illustrative implementation manners of this application and their descriptions are used to explain this application, but not to limit this application.

[0024] Refer to Figures 1 to 2 as Figure 1As shown, this embodiment provides a defective chopstick screening device, comprising a frame 1 and a central belt conveyor mechanism 2 arranged on the frame 1 at the same angle and two groups of side belt conveyor mechanisms 4 arranged symmetrically, the inclination angle range of the central belt conveyor mechanism 2 is 30° to 60°, the central belt conveyor mechanism 2 is located between the two groups of side belt conveyor mechanisms 4, the discharging end drive wheel of the central belt conveyor mechanism 2 and the feeding end drive wheel of the side belt conveyor mechanism 4 are coaxially arranged, a central conveyor belt 21 of the central belt conveyor mechanism 2 is provided with a plurality of first dividing baffles 22 distributed at intervals, and a plurality of second dividing baffles 42 distributed at intervals are provided on the side conveyor belts 41 of the side belt conveyor mechanism 4, the width of the central conveyor belt 21 of the central belt conveyor mechanism 2 is less than the length of the chopsticks 100 so that the two ends of the chopsticks 100 are suspended during the conveying process, and the gap between the two groups of side belt conveyor mechanisms 4 is less than the length of the chopsticks 100. The length of 0 ensures that the two ends of the chopsticks 100 can be respectively placed on the side conveyor belts 41 of the corresponding side belt conveyor mechanism 4. The chopsticks 100 are in a suspended state in the middle when transported by two sets of side belt conveyor mechanisms 4. The frame 1 is provided with two end baffles 11 for guiding the transportation of chopsticks 100. The end baffles 11 are used to abut against the corresponding ends of the chopsticks 100 to form a transportation channel consistent with the length of the chopsticks 100 between the two end baffles 11, so as to prevent the chopsticks 100 from moving left and right during the transportation process, and automatically guide and align them. The chopsticks 100 transported by the middle conveyor belt 21 and located between the two adjacent first dividing baffles 22 are transferred to the corresponding two adjacent second dividing baffles 42 of the side conveyor belt 41 and then continue to be transported. The chopsticks 100 with unqualified lengths fall freely between the two sets of side belt conveyor mechanisms 4 to be sorted. The principle is simple, the structure is simple, the cost is low, and the sorting efficiency is high. The setting of the first partition baffle 22 and the second partition baffle 42 can prevent the chopsticks 100 from sliding down automatically. The inclined setting of the conveying device can make all the chopsticks 100 arranged in parallel and side by side, and the conveying direction of the chopsticks 100 and the median conveyor belt 21 are perpendicular to each other. By adjusting the position, the possibility of the chopsticks 100 being missorted is reduced. The two end baffles 11 cooperate with the median belt conveyor mechanism 2 to form a U-shaped channel, which can prevent the chopsticks 100 from falling during the process of the median belt conveyor mechanism 2.

[0025] In the present application, it is preferred that the transmission wheels of the middle belt conveyor mechanism 2 and the transmission wheels of the side belt conveyor mechanism 4 are both sprockets. Compared with belt conveyors, the sprockets enable the middle conveyor belt 21 and the side conveyor belts 41 to run reliably without slipping, thereby ensuring reliable transportation of the chopsticks 100. The middle conveyor belt 21 and the side conveyor belts 41 are plastic chain plates or stainless steel chain plates.

[0026] In the present application, the inclination angle of the median belt conveyor mechanism 2 is 45°, and the weight of the chopsticks 100 is used to enable the chopsticks 100 to automatically adjust and align during the climbing conveying process.

[0027] In this application, the driving of the middle belt conveyor mechanism 2 and the side belt conveyor mechanism 4 can be driven independently by corresponding driving mechanisms 6 respectively or driven by the same driving mechanism 6. When using different driving mechanisms 6, the corresponding driving mechanism 6 is power-connected to the driving wheel of the middle belt conveyor mechanism 2, and the corresponding driving mechanism 6 is power-connected to the driving wheel of the corresponding side belt conveyor mechanism 4. When using the same driving mechanism 6, the transmission wheel at the discharge end of the middle belt conveyor mechanism 2 and the transmission wheel at the feed end of the side belt conveyor mechanism 4 are coaxially arranged through a linkage shaft 5. The slave transmission wheels of the two side belt conveyor mechanisms 4 are coaxially arranged through a linkage shaft 5, and the main transmission wheels of the two side belt conveyor mechanisms 4 are coaxially arranged through a synchronous shaft. The driving mechanism 6 is power-connected to the transmission wheel at the feed end of the middle belt conveyor mechanism 2 or the synchronous shaft. By using the same driving mechanism 6 for driving, the middle belt conveyor mechanism 2 and the side belt conveyor mechanism 4 have high synchronism. Among them, the transmission wheels of the middle belt conveyor mechanism 2 and the side belt conveyor mechanism 4 have the same specifications.

[0028] In the embodiment of this application, a chopstick packaging machine 9 is provided at the discharge end of the side belt conveyor mechanism 4. The qualified chopsticks 100 conveyed by the side belt conveyor mechanism 4 will fall into the hopper of the chopstick packaging machine 9. Among them, the chopstick packaging machine 9 is a packaging mechanism in the prior art, such as CN 217396908 U and CN 108082572 B.

[0029] In the embodiment of this application, a storage bin 3 is provided on the frame 1, and the chopsticks 100 falling from the storage bin 3 will fall onto the middle belt conveyor mechanism 2.

[0030] Specifically, a gap matching the diameter of the chopsticks 100 is left between the discharge port of the storage bin 3 and the upper surface of the middle conveyor belt 21 of the middle belt conveyor mechanism 2. The chopsticks 100 located in the gap are conveyed forward as the middle conveyor belt 21 works. In this way, it can be ensured that only one layer of chopsticks 100 can be laid on the middle conveyor belt 21 for conveying, avoiding the defect that the upper layer cannot be sorted due to stacking, and making the sorting accuracy high. Preferably, the storage bin 3 includes a lower baffle perpendicular to the middle conveyor belt 21 and side baffles connected to both sides of the lower baffle. The side baffles are connected to the frame 1. A storage cavity is formed between the lower baffle, the two side baffles and the middle conveyor belt 21. When the middle 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 middle 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 middle conveyor belt 21, making the screening reliable.

[0031] In the embodiments of the present application, multiple first partition baffles 22 are evenly distributed at intervals along the annular shape on the middle conveyor belt 21, and multiple second partition baffles 42 are evenly distributed at intervals along the annular shape on the side conveyor belt 41. During the conveying process, both the first partition baffle 22 and the second partition baffle 42 extend along the width direction of the middle conveyor belt 21. The chopsticks 100 located between two adjacent first partition baffles 22 can be transferred to between the corresponding two adjacent second partition baffles 42. When the middle conveyor belt 21 and the side conveyor belt 41 are horizontally arranged, by using the first partition baffle 22 and the second partition baffle 42, the middle conveyor belt 21 and the side conveyor belt 41 can also reliably drive the chopsticks 100 to move forward during the working process, and can prevent the chopsticks 100 from swinging back and forth, avoiding the qualified chopsticks 100 being accidentally removed due to the back-and-forth swing, resulting in waste of resources.

[0032] In the present application, the distance between two adjacent first partition baffles 22 is the same as the distance between two adjacent second partition baffles 42, ensuring that the chopsticks 100 located between two adjacent first partition baffles 22 can be completely transferred to between the corresponding two adjacent second partition baffles 42, and avoiding the situation where the second partition baffle 42 lifts the chopsticks 100.

[0033] In the present application, the height of the first partition baffle 22 is preferably 1 cm, and the height of the second partition baffle 42 is preferably 2.5 cm.

[0034] In the present application, the height of the first partition baffle 22 can also be equal to the width of the chopsticks 100, and the height of the second partition baffle 42 is 1 cm higher than the width of the chopsticks 100.

[0035] In the present application, when the distance between two end baffles 11 can be adjusted, one setting method of the end baffle 11 is that the end baffle 11 is located outside the corresponding side belt conveyor mechanism 4; another setting method of the end baffle 11 is that the end baffle 11 abuts against the top surface of the side conveyor belt 41, and multiple notch grooves are provided on the second partition baffle 42, and the end baffle can be inserted into the notch grooves.

[0036] In this application, the length specifications of the commonly used chopsticks 100 are 240 mm, 240.5 mm, 270 mm, and 270.2 mm. The preferred distance between the two end baffles 11 is 241 mm, 242 mm, 271 mm, and 272 mm. When the distance between the two end baffles 11 is 241 mm, it is used for the conveying and screening of the chopsticks 100 with a length of 240; when the distance between the two end baffles 11 is 241 mm, it is used for the conveying and screening of the chopsticks 100 with a length of 240 mm; when the distance between the two end baffles 11 is 242 mm, it is used for the conveying and screening of the chopsticks 100 with a length of 240.5 mm; when the distance between the two end baffles 11 is 271 mm, it is used for the conveying and screening of the chopsticks 100 with a length of 270 mm; when the distance between the two end baffles 11 is 272 mm, it is used for the conveying and screening of the chopsticks 100 with a length of 270.2 mm. The distance between the two end baffles 11 is usually set 1 - 2 mm larger than the length of the chopsticks 100, which can avoid the situation of jamming and immobility caused by uneven machining accuracy of the chopsticks 100, and can also guide and limit the movement of the chopsticks 100.

[0037] In this application, the preferred distance between the two side belt conveying mechanisms 4 is 230 mm and 260 mm. When the distance between the two side belt conveying mechanisms 4 is 230 mm, it is used for the screening of the chopsticks 100 with lengths of 240 mm and 240.5 mm; when the distance between the two side belt conveying mechanisms 4 is 260 mm, it is used for the screening of the chopsticks 100 with lengths of 270 mm and 270.2 mm.

[0038] In the embodiments of this application, different specifications of chopsticks 100 can be screened by fixing the gap between the two side belt conveying mechanisms 4 or by adjusting the gap between the two side belt conveying mechanisms 4 to screen the corresponding specifications of chopsticks 100 respectively. When the gap between the two side belt conveying mechanisms 4 needs to be adjusted, it can be achieved by moving the driving wheel of the side belt conveying mechanism 4 axially. The specific structure is that the driving wheel is slidably connected to the shaft, and the position of the driving wheel is locked by screwing and pressing.

[0039] In the embodiments of this application, a guide plate 7 near the discharge end is provided between the two side belt conveying mechanisms 4, and the lower end of the guide plate 7 extends above the hopper of the chopstick packaging machine 9. The guide plate 7 is used to ensure that the qualified chopsticks 100 on the two side belt conveying mechanisms 4 can reliably enter the hopper of the chopstick packaging machine 9.

[0040] In the embodiments of this application, a defective product receiving funnel 8 is provided between the two side belt conveying mechanisms 4, and a receiving basket can be placed below the defective product receiving funnel 8.

[0041] During use, the chopsticks 100 located in the storage bin 3 will fall onto the middle-position belt conveyor mechanism 2. The middle-position belt conveyor mechanism 2 operates to drive the continuous conveyance of the chopsticks 100. When the chopsticks 100 move to the tail of the middle-position belt conveyor mechanism 2, both ends of the chopsticks 100 are placed on two groups of side-position belt conveyor mechanisms 4. The side-position belt conveyor mechanisms 4 operate to drive the chopsticks 100 to continue moving forward. Since there is a hollow state between the two groups of side-position belt conveyor mechanisms 4, the defective chopsticks whose ends cannot be placed on the side-position belt conveyor mechanisms 4 will fall into the defective product receiving funnel 8. The qualified chopsticks 100 will fall into the hopper of the chopstick packaging machine 9 along the guide plate 7 and wait for packaging. The sorting and packaging processes do not require manual cooperation, are clean and hygienic, and the quality is controllable.

[0042] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the embodiments of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
