Description

Technical Field

[0001] The utility model relates to the technical field of rolling sorting and transporting equipment, in particular to a self-rotating material sorting structure. Background Technique

[0002] In the production of materials with a circular or approximately circular cross-section, such as in fruit and vegetable sorting, rolling sorting and transporting equipment is usually used to screen the produced materials. Rolling sorting and transporting realizes the pits for sorting materials through the regular arrangement of bead chains or bead strings.

[0003] For example, in the prior art with the application number 201811064386.7, a disclosed fruit and vegetable screening machine includes a conveying mechanism, an image acquisition device, a fruit and vegetable turning mechanism, a plurality of sorting channels, an ejecting device and a central control system. The central control system includes an intelligent recognition module. The conveying mechanism includes a plurality of conveying units, and each conveying unit transports a single fruit and vegetable. The ejecting device includes a plurality of ejecting groups corresponding to the plurality of channels. When the conveying unit moves below the image acquisition device, the fruit and vegetable turning mechanism drives the fruit and vegetable in the conveying unit to rotate. The image acquisition device acquires an image of the fruit and vegetable and sends the acquired image information to the intelligent recognition module for recognition. The central control system classifies the fruit and vegetables in each conveying unit according to the recognition result and controls the corresponding ejecting unit to make a delayed ejecting action according to the classification result, thereby screening and classifying the fruit and vegetables and improving the production efficiency.

[0004] However, under the traditional structure, the bead chain or bead string usually does not rotate automatically during the feeding process, so that the feeding direction and position of the material cannot be sorted out. However, due to the irregular size of the sorted material, after randomly falling into the pit, there are often situations where there are multiple materials in a single pit or there are empty pits, thus reducing the sorting efficiency of the equipment. Therefore, we need to propose a self-rotating material sorting structure to solve the above problems, so that the material can rotate at a high speed during feeding, and the direction and position of the material can be sorted out through the rotation of the material. Content of the Utility Model

[0005] The purpose of the utility model is to provide a self-rotating material sorting structure. Through the cooperation of a chain transmission mechanism, a self-rotating component and a bead string, when the bead string moves driven by the chain transmission mechanism, the self-rotating component can rotate each bead string, forcing the material to rotate at a high speed, and sorting out the direction and position of the material through the rotation of the material. Under the rotation, the material can easily jump from one pit to another nearby pit to solve the problems raised in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: a self-rotating material sorting structure, including: a frame located at the feeding place of the rolling sorting and transporting equipment, and a plurality of bead strings for material transmission are installed at the upper end of the frame;

[0007] A chain drive mechanism for driving a bead string to move on a rolling sorting and transporting device. Chain drive mechanisms are installed on both sides inside the frame, and both ends of multiple groups of bead strings are respectively connected to the chain drive mechanisms.

[0008] A self-rotation assembly for causing multiple groups of bead strings to rotate. The self-rotation assembly is installed inside the frame, and when the chain drive mechanism performs a driving operation, the self-rotation assembly drives the bead strings to rotate.

[0009] Preferably, multiple groups of bead strings are arranged at equal intervals. Each group of bead strings includes a core shaft. An axle sleeve is rotatably connected to the outer wall of the core shaft, and a number of beads with mutually abutting ends are sleeved outside the axle sleeve.

[0010] While the transmission gear meshes with the toothed plate and rotates, it can drive the axle sleeve to rotate around the core shaft, so as to achieve the purpose of the self-rotation of the bead string.

[0011] Preferably, the chain drive mechanism includes a transmission chain distributed inside the rolling sorting device and a plurality of driving sprockets uniformly installed on the side wall of the rolling sorting device. The transmission chain is sleeved on the plurality of driving sprockets, and a motor is installed at one end of the driving sprocket.

[0012] The motor drives the driving sprocket to rotate, and the engagement between the driving sprocket and the transmission chain drives the transmission chain to perform circular movement, so as to drive the bead string to move to different positions on the rolling sorting and transporting device by using the movement of the transmission chain.

[0013] Preferably, the transmission chain is an annular structure formed by sequentially hinging a plurality of chain plates through pin shafts, and a through hole for one end of the core shaft to pass through is formed on the pin shaft. A retaining block is clamped and installed at one end of the core shaft passing through the through hole.

[0014] The through hole facilitates the core shaft to be movably inserted into the through hole. The retaining block can be disassembled according to actual use requirements to disassemble, maintain and clean the bead string. Through the setting of the retaining block, the core shaft is prevented from falling off the transmission chain, and by using the insertion of the core shaft into the through hole, it is convenient to select and install different numbers of bead strings according to actual use requirements.

[0015] Preferably, the self-rotation assembly includes a toothed plate, a connecting plate, and a plurality of transmission gears respectively installed at one end of the bead string. The plurality of transmission gears are all meshed on the toothed plate, and both ends of the toothed plate are connected to the frame through the connecting plate.

[0016] By using the engagement between the toothed plate and the multiple gears, the multiple gears passing through the toothed plate can rotate synchronously, so that multiple bead strings can rotate independently. It is a simple physical meshing drive, can be cleaned arbitrarily, is made of food-grade plastic, and does not require lubrication.

[0017] Preferably, the side surface of the bead is trapezoidal, the beads sleeved on the outer wall of the mandrel are arranged symmetrically in pairs, and one end of the transmission gear is fixed to the shaft sleeve;

[0018] When the transmission gear passes through the toothed plate, it can rotate by using the teeth on the transmission gear and the toothed plate. While the transmission gear rotates, it drives the shaft sleeve to rotate, so that the shaft sleeve drives the external beads to rotate, enabling the beads to rotate self - sufficiently.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] 1. Through the cooperation of the chain drive mechanism, the self - rotation component and the bead string, when the bead string moves driven by the chain drive mechanism, each bead string can be rotated self - sufficiently by the self - rotation component. When feeding materials, the self - rotating bead string forces the materials to rotate at high speed. By the self - rotation of the materials, the direction and position of the materials are sorted. Under self - rotation, the materials can easily jump from one pit to another nearby pit, realizing automatic material sorting, thus improving the sorting efficiency of the materials.

[0021] 2. By rotating the materials self - sufficiently during feeding, the major axis of the materials will be parallel to the bead string and the minor axis will be perpendicular to the advancing direction due to the self - rotation of the materials. When the materials reach the shooting area, it is easy to obtain 360 - degree panoramic photos of the materials, which is beneficial for 360 - degree angle shooting during visual recognition in the later stage of the rolling sorting and transportation equipment.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-5 , the present utility model provides a technical solution: a self-rotating material sorting structure, including: a frame 1 at the feeding position of the rolling sorting and transporting device, and a plurality of bead strings 2 for material transmission are installed at the upper end of the frame 1;

[0030] The rolling sorting and transporting device identifies and classifies materials through the regular arrangement of beads in a bead chain or bead string. These beads can be arranged according to colors, sizes or other characteristics to form a specific pattern or sequence, which determines the movement path of the materials and the final classification. For example, in a row of beads, beads of different colors represent different classifications. When the material passes through, it will move along with the beads of the corresponding color or size to achieve automatic classification.

[0031] The plurality of bead strings 2 are arranged at equal intervals. Each bead string 2 includes a mandrel 22. The outer wall of the mandrel 22 is rotatably connected with a bushing. A plurality of beads 21 with mutually abutted ends are sleeved outside the bushing. When the mandrel 22 rotates by meshing with a toothed plate 31 through a transmission gear 33, the bushing can be driven to rotate around the mandrel 22 as the axis, so as to achieve the purpose of the self-rotation of the bead string 2.

[0032] A chain drive mechanism for driving the bead string 2 to move on the rolling sorting and transporting device. Chain drive mechanisms are installed on both sides inside the frame 1, and both ends of the plurality of bead strings 2 are respectively connected to the chain drive mechanism, so as to facilitate driving the bead string 2 to move on the rolling sorting and transporting device through the chain drive mechanism;

[0033] The chain drive mechanism includes a transmission chain 4 distributed inside the rolling sorting device and a plurality of drive sprockets 5 uniformly installed on the side wall of the rolling sorting device. The transmission chain 4 is sleeved on the plurality of drive sprockets 5. One end of the drive sprocket 5 is installed with a motor. The drive sprocket 5 is driven to rotate by the motor, and the transmission chain 4 is driven to perform circular movement by the meshing of the drive sprocket 5 and the transmission chain 4, so as to drive the bead string 2 to move to different positions on the rolling sorting and transporting device by the movement of the transmission chain 4.

[0034] The drive chain 4 is an annular structure formed by sequentially hinging a plurality of chain plates through a pin shaft. A through hole for one end of the core shaft 22 to pass through is provided on the pin shaft, so that the core shaft 22 is movably inserted into the through hole. The stopper can be disassembled according to actual use requirements to disassemble, maintain and clean the bead string 2. One end of the core shaft 22 passes through the through hole and is snap-fitted with a stopper. Through the setting of the stopper, the core shaft 22 is prevented from falling off the drive chain 4, and by using the insertion of the core shaft 22 into the through hole, it is convenient to select and install different numbers of bead strings 2 according to actual use requirements.

[0035] A self-rotation assembly 3 for rotating multiple bead strings 2. The self-rotation assembly 3 is installed inside the frame 1, and the self-rotation assembly 3 drives the bead strings 2 to rotate automatically when the chain drive mechanism is in transmission operation. When the bead strings 2 move normally, the bead strings 2 are rotated in the same direction. The bead strings 2 rotating at high speed will cause the material to be automatically sorted while being transported forward. For multiple material pits, due to the rotational movement of the material, ultimately only one material will remain in the most stable state and be transported forward, and the excess materials will jump to other empty pits by themselves;

[0036] The self-rotation assembly 3 includes a toothed plate 31, a connecting plate 32, and a plurality of drive gears 33 respectively installed at one end of the bead string 2. The plurality of drive gears 33 are all engaged with the toothed plate 31. Both ends of the toothed plate 31 are connected to the frame 1 through the connecting plate 32. By using the engagement of the toothed plate 31 with the multiple gears, the multiple gears passing through the toothed plate 31 can rotate synchronously, so that the multiple bead strings 2 can rotate independently. It is a simple physical meshing transmission, can be cleaned arbitrarily, and is made of food-grade plastic without lubrication.

[0037] The side surface of the bead 21 is trapezoidally arranged. The beads 21 sleeved on the outer wall of the core shaft 22 are arranged in pairs symmetrically, and the drive gear 33 is fixed to one end of the bushing. When the drive gear 33 passes through the toothed plate 31, it can rotate by using the teeth on the drive gear 33 and the toothed plate 31. While the drive gear 33 rotates, it drives the bushing to rotate, so that the bushing drives the external beads 21 to rotate, enabling the beads 21 to rotate automatically.

[0038] Through the cooperation of the chain drive mechanism, the self-rotation assembly 3 and the bead string 2, when the bead string 2 moves driven by the chain drive mechanism, each bead string 2 can be rotated by the self-rotation assembly 3. When feeding the material, the rotating bead string 2 is used to force the material to rotate at high speed. By the rotation of the material, the direction and position of the material are sorted. Under self-rotation, the material can easily jump from one pit to another nearby pit, realizing automatic sorting of the material, thereby improving the sorting efficiency of the material; in addition, the self-rotation of the material will make the long diameter of the material parallel to the bead string 2 and the short diameter perpendicular to the advancing direction. When the material reaches the shooting area, it is easy to obtain a 360-degree panoramic photo of the material, which is beneficial for 360-degree angle shooting during the visual recognition of the latter section of the rolling sorting and transportation equipment.

[0039] For example, when a rolling sorting and transporting device is used for fruit and vegetable screening, beads of different colors represent different classification categories. When fruits and vegetables pass through, they will move along with the beads of the corresponding color or size to achieve automatic classification. This classification method not only improves production efficiency but also ensures that each fruit and vegetable meets the quality standards. In addition, the rolling sorting and transporting device usually includes parts such as a conveying mechanism, an image acquisition device, a fruit and vegetable turning mechanism, a sorting system, and a central control system. Among them, the image acquisition device is used to obtain the apparent information of fruits and vegetables, and the intelligent recognition module identifies and classifies fruits and vegetables based on this information. The central control system then controls the ejecting device to eject the fruits and vegetables into the corresponding sorting channels according to the classification results. This rolling sorting and transporting device is prior art, such as a fruit and vegetable screening machine disclosed in the patent document with the application number 201811064386.7, so it will not be described in detail here.

[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
