Description

Technical Field

[0001] The invention relates to the field of color sorting and packaging, and specifically to an integrated intelligent color selection and intelligent packaging device for producing bamboo chopsticks. Background Art

[0002] Chopsticks are long and thin sticks that are held between the fingers to pick up food or other things. They are mostly used as tableware. They are made of bamboo, wood, ivory, bone, metal, etc., and have different shapes, such as square or round. Bamboo chopsticks are increasingly being used as the preferred eating utensil in the catering industry because of their light weight, easy transportation, low cost, safety and hygiene.

[0003] In order to improve the quality of bamboo chopsticks, they are first color-sorted before packaging, and those with poor color are removed. This requires spreading the chopsticks out and then selecting and marking them with visual equipment and removing the marked individuals with the help of a gripping mechanism. In addition, the chopsticks are integrated and sorted before subsequent packaging, which results in the overall production line being too long, increasing the floor space and significantly reducing production efficiency, affecting the control of overall production costs.

[0004] Therefore, a new type of intelligent color selection and intelligent packaging integrated equipment for bamboo chopstick production is needed to solve the above problems. Summary of the invention

A friction plate is fixed on the frame and protrudes from the bottom of the material belt groove from the groove on the lower side of the visual color sorting mechanism, and both ends of the friction plate are chamfered.

[0009] As a further solution of the present invention: the edge of one side of the material belt through groove close to the material distribution hopper is rounded.

[0010] As a further solution of the present invention: a press rod extending to the top of the friction plate is fixed on the frame, the surface of the press rod is a smooth surface with lower friction force than the friction plate, and the material strip passes between the friction plate and the press rod.

[0011] As a further solution of the present invention: the pressing rod is composed of two sections of rod structures which are staggered in the conveying direction of the spreading conveyor belt.

[0012] As a further solution of the present invention: a protruding limiting strip is distributed circumferentially on one end of the material belt close to the material distribution hopper, the limiting strip is located within the lateral range of the material discharge hopper, and the limiting strip is half the height of the groove of the material belt.

[0015] As a further solution of the present invention: the distribution hopper includes a circulation hopper and a waste hopper. The circulation hopper has an opening at the top and is fixed at a position 60° obliquely below the material spreading conveyor belt. The tail end is connected to the storage hopper through a loading belt. A waste hopper is fixed on the side wall of the circulation hopper.

[0029] The present embodiment provides an integrated intelligent color selection and intelligent packaging equipment for bamboo chopstick production, comprising a material spreading conveyor belt 1 with grooves corresponding to the shape of bamboo chopsticks on the surface, a discharging hopper 2 is fixed above one end of the material spreading conveyor belt 1 for discharging the bamboo chopsticks, a visual color selection mechanism 3 facing vertically downward at the tail end of the discharging hopper 2 is provided to color-select and mark the bamboo chopsticks on the material spreading conveyor belt 1, a speed-adjustable pushing mechanism 6 is fixed to one side of the material spreading conveyor belt 1 to push out the marked bamboo chopsticks laterally, a high and low position dividing hopper 4 is provided on the other side of the material spreading conveyor belt 1 to divert the pushed out bamboo chopsticks, and the low position part is fed into the pushing mechanism 6 through the feeding belt 514, a packaging mechanism 8 is fixed to one side of the end of the material spreading conveyor belt 1, and a discharging push rod 7 is fixed to the opposite side of the packaging mechanism 8 to feed the packaging mechanism 8; The pusher with intact bamboo chopsticks in stock can be used to push out and replace the marked defective bamboo chopsticks among the evenly spread bamboo chopsticks. While the bamboo chopsticks are being spread out and sorted, the defective bamboo chopsticks can be color sorted and removed, which reduces the floor space occupied by the equipment and improves the color sorting efficiency.

[0030] Among them, the material spreading conveyor belt 1 includes a frame 11, a driving motor 12, a driving shaft 13 and a material belt 14. The driving shaft 13 driven by the driving motor 12 is rotatably arranged at both ends of the frame 11. The outer side of the driving shaft 13 is sleeved with the material belt 14. The surface of the material belt 14 has grooves corresponding to bamboo chopsticks, and the two ends of the groove are open structures to facilitate the lateral pushing out and replacement of the bamboo chopsticks.

[0031] Specifically, there are through grooves distributed along the circumferential direction of the material belt 14 on the material belt 14, and the material belts 14 on both sides of the through groove are connected by a groove structure. A friction plate 15 is fixed on the frame 11 and extends out from the bottom of the groove of the material belt 14 at the groove on the lower side of the visual color sorting mechanism 3, and both ends of the friction plate 15 are chamfered; As a result, when the bamboo chopsticks pass through the lower side of the visual color sorting mechanism 3, they come into contact with the friction plate 15 and generate axial rotation through friction, so that the visual color sorting mechanism 3 can perform full-angle color sorting on the bamboo chopsticks.

[0032] Furthermore, the edge of one side of the through slot of the material belt 14 close to the material distribution hopper 4 is rounded to prevent the replaced bamboo chopsticks from lateral conflict with the through slot structure when being pushed out.

[0033] Furthermore, a pressing rod 17 extending to the top of the friction plate 15 is fixed on the frame 11, and the surface of the pressing rod 17 is a smooth surface with a lower friction force than the friction plate 15, and the material strip 14 passes between the friction plate 15 and the pressing rod 17; The pressing rod 17 is used to limit the upper part of the bamboo chopsticks, so as to prevent the friction force of the bamboo chopsticks from being too small to cause circumferential rotation after the bamboo chopsticks are lifted up by the friction plate 15.

[0034] Furthermore, the pressing rod 17 is composed of two rod structures staggered in the conveying direction of the spreading conveyor belt 1 to avoid the pressing rod 17 structure from continuously shielding a certain point on the axial direction of the bamboo chopsticks and preventing the color selection mark from being affected.

[0035] Specifically, a protruding limiting strip 16 is distributed in an annular direction at one end of the material belt 14 close to the material distribution hopper 4. The limiting strip 16 is located in the lateral range of the material discharge hopper 2, and the limiting strip 16 is one-half of the height of the groove of the material belt 14. By setting the limiting strip 16, the movement of the pusher pushing out the intact chopsticks to replace the marked chopsticks is limited to avoid excessive pushing out.

[0036] Furthermore, the height of the discharging push rod 7 is higher than the limiting strip 16 to avoid the discharging push rod 7 from colliding with the end surface of the limiting strip 16 during discharging.

[0037] The pushing mechanism 6 includes a storage hopper 61, a hydraulic cylinder 62 and a material changing push rod 63. A groove corresponding to the shape of a bamboo chopstick is provided at the bottom of the storage hopper 61. A hole is opened on one side of the groove, and a hydraulic cylinder 62 is fixed on the other side. A material changing push rod 63 is provided in the hydraulic cylinder 62 and extends along the direction of the groove. The material changing push rod 63 is arranged parallel to the groove of the material spreading conveyor belt 1. By setting the groove at the bottom of the discharge hopper and the telescopic material replacement push rod 63 on one side, and by controlling the telescopic state of the material replacement push rod 63, the filling and pushing or empty pushing processing of the corresponding groove position can be realized, thereby realizing the replacement and pushing or empty pushing processing of the bamboo chopsticks on the material spreading conveyor belt 1.

[0038] Specifically, the material distribution hopper 4 includes a circulation hopper 41 and a waste hopper 42. The circulation hopper 41 has an opening at the top and is fixed at a position 60° obliquely below the material spreading conveyor belt 1. The tail end is connected to the storage hopper 61 through a feeding belt 514. A waste hopper 42 is fixed on the side wall of the circulation hopper 41. The waste hopper 42 semi-shiels the opening above the circulation hopper 41. The distance between the edge of the waste hopper 42 and the material spreading conveyor belt 1 is greater than half the width of the material spreading conveyor belt 1. By adjusting the relative positions of the circulation hopper 41 and the waste hopper 42 and controlling the pushing force during pushing, the intact bamboo chopsticks and the marked bamboo chopsticks can be pushed into the circulation hopper 41 and the waste hopper 42 for circulation filling and selection and discharge.

[0039] When implementing the technical solution recorded in this embodiment, the processed bamboo chopsticks are fed into the discharge hopper 2, and fit into the grooves on the material belt 14 of the material spreading conveyor belt 1 one by one, and the bamboo chopsticks are spread out. Driven by the material spreading conveyor belt 1, the bamboo chopsticks move to the lower side of the visual color sorting mechanism 3, and rotate circumferentially under the friction force of the friction plate 15. The visual color sorting mechanism 3 marks the bamboo chopsticks with surface defects. When the marked bamboo chopsticks move to the pusher position, the material replacement push rod 63 in the pusher corresponding to the marked bamboo chopstick is retracted from the initial position of the shielding groove. , the corresponding groove is filled with bamboo chopsticks with intact surfaces. After filling, the material replacement push rod 63 at this position and its adjacent position on the left is pushed out horizontally, and the marked bamboo chopsticks are replaced by bamboo chopsticks with intact surfaces. At the same time, the intact bamboo chopsticks in the groove on the left side of the replacement position are also pushed out of the material spreading conveyor 1. By controlling the lateral pushing speed, the intact bamboo chopsticks enter the circulation bucket 41 and the storage bucket 61 for replenishment of replacement bamboo chopsticks, while the marked bamboo chopsticks enter the waste bucket 42 for discharge. Subsequently, the bamboo chopsticks after color sorting are pushed into the packaging machine by the discharging push rod 7 for packaging.
