Description

Technical Field

[0001] The utility model relates to the technical field of rolling sorting and transporting equipment, in particular to a differential rotation structure. Background Art

[0002] Rolling sorting and transporting equipment is a mechanical device specially used for material classification and transportation. Its core lies in the use of regular arrangement of bead chains or bead strings to achieve accurate sorting of different materials. Currently, rolling sorting and transporting equipment is often used in the screening of fruits and vegetables to screen the size of fruits and vegetables.

[0003] During rolling sorting, the primary goal is to capture a 360-degree panoramic image of the material. Only by capturing images of the entire material's circumference can the algorithm accurately identify the material. Because the bead chain moves at such high speeds, traditional manufacturers use a large synchronous wheel to drive the bead chain, which rotates in conjunction with a rack fixed to the machine frame, to achieve 360-degree rotation of the material within the imaging area. This reduces the material's rotation speed within the imaging area and thus matches the frequency of the images.

[0004] However, due to the large difference in rotation speed between the particularly large synchronous wheel and the bead chain, the outer diameter of the self-rotating synchronous wheel at the end of the bead string is relatively large, and it needs to be staggered left and right with the adjacent wheel. The structure is complex and occupies a large width. In addition, the forward speed of the host during equipment operation will be adjusted according to the state of the material, and the fixed wheel diameter cannot match the speed range of the host. As a result, at some host speeds, the shooting angle of the material cannot meet 360 degrees, thereby reducing the sorting accuracy. Therefore, we need to propose a differential rotation structure to solve the above problems, so that it can freely control the rotation speed of the bead string in the required area, thereby meeting the requirements of shooting or other areas for the rotation speed of the material to improve the sorting accuracy. Utility Model Content

[0005] The purpose of the present utility model is to provide a differential rotation structure that can freely control the rotation speed of the beads in the required area, thereby meeting the requirements of the material rotation speed in shooting or other areas, so as to improve the sorting accuracy and solve the problems raised in the background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a differential rotation structure, comprising: a differential rotation structure body mounted on a rolling sorting and transporting device, the differential rotation structure body comprising a transmission mechanism having teeth on a transmission surface, a support mechanism, and a drive mechanism for driving the transmission mechanism, wherein the support mechanism is located inside the transmission mechanism;

[0007] A bead chain mechanism is used for sorting and transporting materials, wherein the bead chain mechanism is provided with a bead synchronization wheel capable of engaging with a transmission mechanism.

[0009] The inclined surface of the wear-resistant support bar helps the toothed synchronous belt pass over the wear-resistant support bar and reduces the damage to the toothed synchronous belt caused by sharp corners. The wear-resistant support bar supports the toothed synchronous belt, and the middle part of the toothed synchronous belt is occupied by the frame body, which effectively prevents the entry of abnormal materials, protects the belt from damage, and ensures stable transmission of the transmission mechanism.

[0010] Preferably, the transmission mechanism includes a driving pulley, a driven pulley and a toothed synchronous belt, the driving pulley and the driven pulley are respectively located at both ends of the frame, and the driving pulley and the driven pulley are rotatably connected to the connecting plate through a rotating shaft, and the toothed synchronous belt is sleeved on the driving pulley and the driven pulley;

[0011] The double-wheel structure of the driving pulley and the driven pulley makes the drive of the transmission mechanism simple. The rotation of the driving pulley drives the toothed synchronous belt to move in a circle, and the toothed synchronous belt drives multiple bead strings to rotate, so as to perform rolling sorting on the materials.

[0012] Preferably, two connecting plates are fixed to both ends of the frame, the two connecting plates are symmetrically arranged, and both ends of the rotating shaft are rotatably connected to the connecting plates through bearings;

[0013] The driving pulley and the driven pulley are supported by the connecting plate, thereby improving the installation stability of the driving pulley and the driven pulley.

[0014] Preferably, the driving mechanism includes a driving motor, the output shaft of the driving motor is key-connected to one end of the rotating shaft on the driving pulley, and the base of the driving motor is connected to the frame of the rolling sorting and transporting equipment;

[0015] The active motor drives the active pulley to rotate. This direct drive method reduces the probability of structural damage. During adjustment, the speed of the active motor is controlled to achieve speed regulation, thereby controlling the rotation speed of the bead string.

[0016] Preferably, the bead chain mechanism comprises a plurality of self-rotating bead strings, the plurality of bead strings are connected by a transmission chain, and one end of each bead string is provided with a bead synchronization wheel capable of engaging with a toothed synchronous belt;

[0017] When the toothed synchronous belt moves, the bead synchronous wheel is engaged with the toothed synchronous belt to drive the bead string to rotate, so that the material can be sorted when it is transmitted through the bead chain mechanism, thereby improving the material sorting efficiency.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The utility model cooperates with the bead chain mechanism through the differential rotation structure body composed of the transmission mechanism, the support mechanism and the driving mechanism.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-4The utility model provides a technical solution: a differential rotation structure, comprising: a differential rotation structure body 1 installed on a rolling sorting and transporting device, the differential rotation structure body 1 comprising a transmission mechanism with teeth on a transmission surface, a support mechanism, and a drive mechanism for driving the transmission mechanism, the support mechanism being located on the inner side of the transmission mechanism so that the middle part of the transmission mechanism is occupied by the support mechanism, effectively preventing the entry of abnormal materials and protecting the transmission mechanism from damage;

[0028] The rolling sorting and transporting equipment includes 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 appearance information of fruits and vegetables, and the intelligent recognition module identifies and classifies fruits and vegetables based on this information. The central control system controls the ejection device to push the fruits and vegetables into the corresponding sorting channel according to the classification results. This rolling sorting and transporting equipment is a prior art. For example, the patent application number is 201811064386.7, which discloses a fruit and vegetable screening machine. Its structure is the same as that of the rolling sorting and transporting equipment, so it will not be described in detail here.

[0029] The supporting mechanism includes a frame 11, a connecting plate 16 and wear-resistant support strips 14 located on both sides of the frame 11. Both ends of the wear-resistant support strips 14 are provided with inclined surfaces. The two ends of the frame 11 are connected to the side walls of the rolling sorting and transportation equipment through the connecting plates 16; the inclined surfaces help to make the toothed synchronous belt 15 pass over the wear-resistant support strips 14 and reduce the damage to the toothed synchronous belt 15 caused by sharp corners. The toothed synchronous belt 15 is supported by the wear-resistant support strips 14, and the middle part of the toothed synchronous belt 15 is occupied by the main body of the frame 11, which effectively prevents the entry of abnormal materials, protects the belt from damage, and ensures the stable transmission of the transmission mechanism.

[0030] The transmission mechanism includes a driving pulley 13, a driven pulley 12 and a toothed synchronous belt 15. The driving pulley 13 and the driven pulley 12 are respectively located at both ends of the frame 11, and the driving pulley 13 and the driven pulley 12 are rotatably connected to the connecting plate 16 through a rotating shaft 18. The toothed synchronous belt 15 is sleeved on the driving pulley 13 and the driven pulley 12. The double-wheel structure of the driving pulley 13 and the driven pulley 12 makes the driving of the transmission mechanism simple. The rotation of the driving pulley 13 drives the toothed synchronous belt 15 to move in a circle, so that the toothed synchronous belt 15 drives multiple bead strings 3 to rotate, so as to perform rolling sorting of the materials.

[0031] Two connecting plates 16 are fixed at both ends of the frame 11. The two connecting plates 16 are symmetrically arranged. The two ends of the rotating shaft 18 are rotatably connected to the connecting plates 16 through bearings. The connecting plates 16 support the driving pulley 13 and the driven pulley 12, thereby improving the installation stability of the driving pulley 13 and the driven pulley 12.

[0032] The driving mechanism includes an active motor 17, the output shaft of the active motor 17 is keyed to one end of the rotating shaft 18 on the active pulley 13, and the base of the active motor 17 is connected to the frame of the rolling sorting and transportation equipment. The active pulley 13 is driven to rotate by the active motor 17. This direct drive method reduces the probability of structural damage. During adjustment, speed regulation is achieved by controlling the speed of the active motor 17, thereby controlling the rotation speed of the bead string 3.

[0033] A bead chain mechanism for sorting and transmitting materials is provided with a bead synchronous wheel 2 that can engage with the transmission mechanism; the bead chain mechanism includes a plurality of bead strings 3 that can rotate, and the plurality of bead strings 3 are connected by a transmission chain 4. One end of each bead string 3 is provided with a bead synchronous wheel 2 that can engage with a toothed synchronous belt 15, so that when the toothed synchronous belt 15 moves, the bead synchronous wheel 2 is engaged with the toothed synchronous belt 15 to drive the bead string 3 to rotate, so that the material can be sorted when it is transmitted through the bead chain mechanism, thereby improving the sorting efficiency of the material. This equipment is suitable for sorting materials such as wooden sticks for pencils. The pencils are formed by clamping the pencil lead in the center of the wooden stick, and the wooden stick is used as the pencil body. The cross-section of the pencil body is circular or approximately circular.

[0034] During use, the active motor 17 drives the active pulley 13 to rotate, and the active pulley 13, the toothed synchronous belt 15 and the driven pulley 12 cooperate to make the toothed synchronous belt 15 move in a circle. While the toothed synchronous belt 15 moves in a circle, the toothed synchronous belt 15 is engaged with the bead synchronous wheel 2 to make the bead synchronous wheel 2 rotate through the movement of the toothed synchronous belt 15, thereby making the bead string 3 rotate, so as to facilitate automatic material sorting during material loading. Since the active motor 17 directly drives the active pulley 13, the moving speed of the toothed synchronous belt 15 can be adjusted by adjusting the speed of the active motor 17. Therefore, the differential rotation speed can be adjusted according to the actual material diameter and the forward speed of the active motor 17, thereby meeting the material rotation speed requirements of shooting or other areas.
