Description

Technical Field

[0001] The utility model relates to the technical field of visual selection, in particular to a conveying device and a visual selection machine. Background Art

[0002] As is known, in a visual selection machine in the visual selection field, a conveyor belt is usually driven by a conveying roller of a conveying device to convey materials to be screened (such as walnuts with husks). A visual recognition mechanism in the visual selection machine recognizes the materials on the conveyor belt to identify features such as the quality, shape, and type of the materials. Then, the planar position of the recognized materials is located. Based on the position information and the movement information of the conveyor belt, a rejection mechanism rejects the recognized materials that need to be rejected.

[0003] Generally, a vibrating mechanism is further provided at the rear end of the conveying device. A discharging component of the vibrating mechanism and the conveyor belt are configured with a certain height difference, and an inclined feeding chute is provided between the front end of the discharging component and the conveyor belt. The materials discharged from the front end of the discharging component fall along the feeding chute and land on the conveyor belt.

[0004] However, there are the following problems when the materials fall onto the conveyor belt via the feeding chute:

[0005] Under the action of gravity, when the materials fall onto the conveyor belt along the feeding chute in a rolling manner or a combination of rolling and sliding, the materials may undergo lateral movement and, due to the lateral movement, finally come to rest (land) in the edge area of the conveyor belt, or even roll out of the conveyor belt from the edge. The materials located in the edge area may be difficult to be recognized by the recognition mechanism and difficult to be rejected by the rejection mechanism, and the materials rolling out of the conveyor belt will cause material loss. Summary of the Utility Model

[0006] In view of the above problems existing in the prior art, the purpose of the present utility model is to provide a conveying device and a visual selection machine to solve the problems in the prior art.

[0007] To achieve the above purpose, the present utility model adopts the following solutions.

[0008] A conveying device includes: a conveying roller and a conveyor belt installed on the conveying roller. The conveying device further includes a pressing component; wherein:

[0009] The pressing component is arranged in the rear section of the conveyor belt and in front of the vibrating mechanism of the visual selection machine;

[0010] The squeezing member has side walls that are symmetrically arranged on both sides in the width direction of the conveyor belt. The two side walls squeeze the conveyor belt so that a limiting groove with a lower middle and higher sides is formed on the conveyor belt. The limiting groove is used to guide the material that falls from the vibrating mechanism onto the conveyor belt to rest in the middle region in the width direction of the conveyor belt.

[0011] Preferably, the two symmetrically arranged side walls of the squeezing member are inclined outward in the width direction of the conveyor belt.

[0012] Preferably, roller bodies are installed on the two symmetrically arranged side walls of the squeezing member, and the side walls squeeze the conveyor belt by contacting the side edges of the conveyor belt through the roller surfaces of the roller bodies.

[0013] Preferably, at least two roller bodies arranged in parallel are installed on each side wall.

[0014] Preferably, a plurality of the squeezing members are arranged at intervals along the conveying direction of the conveyor belt.

[0015] Preferably, there are a plurality of conveyor belts, and the plurality of conveyor belts are arranged side by side on the conveyor rollers; the squeezing member is provided in the rear section of each conveyor belt.

[0016] The present utility model also discloses a visual selection machine, including: an identification mechanism, a rejection mechanism, and a vibrating mechanism. It is characterized in that the visual selection machine further includes the above-mentioned conveying device; the vibrating mechanism is located at the rear end of the conveyor belt of the conveying device, and the squeezing member of the conveying device is arranged in the rear section of the conveyor belt and in front of the vibrating mechanism.

[0017] Preferably, an inclined material dropping chute is arranged between the front end of the material discharging member of the vibrating mechanism and the conveyor belt.

[0018] Compared with the prior art, the advantages of the conveying device and the visual selection machine provided by the present utility model are:

[0019] The conveying device provided by the present utility model is configured with a squeezing member. Thus, if a certain material discharged from the material discharging member and passing through the material dropping chute generates a lateral offset during the process of falling onto the conveyor belt, the limiting groove with higher sides and lower middle will correct the lateral movement of the material to guide the material to finally rest in the middle of the conveyor belt. This can not only effectively reduce the probability of the material rolling off the conveyor belt, but also has a centering effect on the material, which is beneficial to improving the recognition accuracy of the recognition mechanism and the rejection accuracy of the rejection mechanism.

[0031] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted in this utility model.

[0032] As Figure 1 shown, an embodiment of this utility model discloses a conveying device 100 and a vision sorter including the conveying device 100. The vision sorter further includes: an identification mechanism (not shown in the drawings), a rejection mechanism 300, and a vibrating mechanism (not shown in the drawings); the conveying device 100 includes front and rear arranged conveying rollers (not shown in the drawings), a conveyor belt 10 mounted on the conveying rollers, and a pressing member 20; the vibrating mechanism is located at the rear end of the conveyor belt 10 of the conveying device 100, and the vibrating mechanism has a material discharging member. There is a height difference between the material discharging member and the conveyor belt 10. Materials 400 such as walnut with skin are discharged from the front end of the material discharging member and fall onto the conveyor belt 10 by means of gravity. The forward movement of the conveyor belt 10 causes the materials 400 to be arranged at intervals on the conveyor belt 10. The identification mechanism is located above the conveyor belt 10 and is used to identify the materials 400 on the conveyor belt 10. The rejection mechanism 300 is located in front of (downstream of) the identification mechanism, and the rejection mechanism 300 performs a rejection operation on the materials 400 identified by the identification mechanism.

[0033] In some preferred structures, a plurality of conveyor belts 10 with smaller width dimensions are arranged between the conveying rollers. The plurality of conveyor belts 10 are arranged side by side, and each conveyor belt 10 is used to receive the materials 400 from the material discharging member and is responsible for conveying a row of materials 400. Correspondingly, both the identification mechanism and the rejection mechanism 300 include multiple groups corresponding one-to-one to the plurality of conveyor belts 10, and each group of the identification mechanism and the rejection mechanism 300 is responsible for identifying and rejecting the materials 400 on the corresponding conveyor belt 10.

[0034] In some preferred structures, a material dropping chute 200 inclined in the conveying direction is disposed between the front end of the material discharging member of the vibrating mechanism and each conveyor belt 10. The material 400 discharged from the front end of the material discharging member falls along the material dropping chute 200 and then lands on the conveyor belt 10, thereby preventing the material 400 from bouncing when it lands on the conveyor belt 10.

[0035] The key to the visual selection machine provided by the present utility model lies in: as Figure 1 and in combination with Figures 2 to 4 As shown, an extrusion member 20 is disposed in the rear section of the conveyor belt 10. Specifically, the extrusion member 20 has two side walls 21 arranged symmetrically. The two side walls 21 are located on both sides in the width direction of the conveyor belt 10, and the two side walls 21 extrude the conveyor belt 10 toward the inner side in the width direction of the conveyor belt 10, so that the conveyor belt 10 is deformed to form a limiting groove 11 with a lower middle part and higher two sides. In this way, if a certain material 400 discharged from the material discharging member and passing through the material dropping chute 200 has a lateral offset during the process of landing on the conveyor belt 10, the limiting groove 11 with higher two sides and lower middle part will correct the lateral movement of the material 400 to guide the material 400 to finally stop at the middle part of the conveyor belt 10, that is, to fall into the limiting groove 11. This can not only effectively reduce the probability of the material 400 rolling off the conveyor belt 10, but also has a centering effect on the material 400, which is beneficial to improving the recognition accuracy of the recognition mechanism and the rejection accuracy of the rejection mechanism 300.

[0036] In some preferred structures, as Figure 1 shown, if the conveying device 100 includes a plurality of conveyor belts 10 arranged side by side, an extrusion member 20 is arranged in the rear section of each conveyor belt 10. And, along the conveying direction of the conveyor belt 10, a plurality of extrusion members 20 are arranged at intervals in the rear area of each conveyor belt 10 to extend the length of the limiting groove 11 and improve the centering effect on the material 400.

[0037] In some preferred structures, roller bodies 22 are installed on the two side walls 21 of each extrusion member 20. Preferably, two roller bodies 22 arranged in parallel are installed on each side wall 21. The roller surface of the roller body 22 contacts the side edge of the conveyor belt 10, and the conveyor belt 10 is extruded by the roller body 22 to form the limiting groove 11. The advantage of setting the roller body 22 is that the roller body 22 rotates to adapt to the forward movement of the conveyor belt 10, thereby reducing the wear of the conveyor belt 10.

[0038] In some preferred structures, the two side walls 21 of each extrusion member 20 are inclined outward in the width direction of the conveyor belt 10, which is beneficial for the extrusion cooperation between the conveyor belt 10 and the extrusion member 20 and avoids jamming between the conveyor belt 10 and the extrusion member 20.
