Description

Technical Field

[0001] The utility model relates to the technical field of screening and sieving, in particular to a conveyor belt used in a visual selection machine. Background Art

[0002] As is known, visual screening machines in the screening and sieving field usually utilize conveyor rollers of a conveying device to drive a conveyor belt to convey materials to be screened. The visual recognition mechanism in the visual screening machine identifies the materials on the conveyor belt to identify the quality, shape, type and other characteristics of the materials, and then locates the plane position of the identified materials. Based on the positioning information and the conveying speed of the conveyor belt, the injection mechanism can remove the identified materials to be removed by injecting airflow.

[0003] However, the conveyor belt of the conveying device in the prior art, when used in the visual selection machine, has at least the following effects on the positioning and identification of materials: the conveyor belt may produce lateral movement and longitudinal speed fluctuations during operation, thereby causing the material to move relative to the conveyor belt (such as rolling, translation), which will not only result in inaccurate positioning of the material, but also may cause the image taken by the identification mechanism to be blurred (if the recording equipment in the identification mechanism shoots the material in relative motion, the captured image may be blurred). Utility Model Content

[0004] In view of the above problems existing in the prior art, the purpose of the utility model is to provide a conveyor belt for a visual selection machine to solve the problems in the prior art.

[0031] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Unless otherwise defined, the technical terms or scientific terms used in the present invention shall have the usual meanings understood by persons with ordinary skills in the field to which the present invention belongs. The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" and the like mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" and the like are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0033] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0034] The embodiment of the utility model discloses a visual selection machine conveyor belt, which is used to convey materials, and the materials may be soybeans, dates, peanut kernels, walnuts, etc. When the materials are conveyed along the conveyor belt, an identification mechanism takes pictures of the materials and determines the quality and size of the materials by analyzing the photographed images. Subsequently, the materials are graded and sorted by means of rejection using mechanisms such as airflow injection devices.

[0035] like Figures 1 to 5 As shown, the conveyor belt includes a belt body 10, on which a plurality of hole features 20 are arranged. The hole features 20 are used to receive materials falling on the belt body 10 to limit the movement of the materials relative to the belt body 10. In this way, when the conveyor belt moves laterally and / or generates speed fluctuations in the conveying direction, the materials will not move relative to the conveyor belt due to inertia. The specific reason is that the bottom area of ​​the material sinks into the hole features 20, and the circumferential areas of the edges of the ports of the hole features 20 support the material, thereby limiting the movement of the material relative to the belt body 10.

[0036] Because the material is limited by the hole feature 20, the material can be stably transported by the conveyor belt, and the material will not move relative to the conveyor belt. Therefore, inaccurate positioning will not result, and the probability of blurring of the picture taken by the identification mechanism is greatly reduced, which is conducive to accurate screening of the material.

[0037] In some preferred structures, such as Figure 5 As shown, a conical slope 22 is machined on the periphery of each hole feature 20, and the conical slope 22 is used to guide the material falling on the belt body 10. Specifically, after the material falls on the front end of the conveyor belt, the material can automatically move to the hole feature 20 by applying vibration and be received by the hole feature 20. The conical slope 22 cooperates with the vibration to enable the material to smoothly move to the hole feature 20 and be received by the hole feature 20.

[0038] In some more preferred structures, such as Figure 5 As shown, a blunting portion 21 is processed at the edge of the port of each hole feature 20. Specifically, the blunting portion 21 can be a chamfer or a rounded corner. In this way, for materials with fragile surfaces, after the hole feature 20 receives the material, the edge of the hole feature 20 can significantly reduce the contact stress on the hole feature 20 due to the processing of the blunting portion 21, thereby significantly reducing the damage to the surface of the material.

[0039] In some more preferred structures, all hole features 20 are arranged in a matrix; all hole features 20 are arranged in multiple columns along the width direction of the belt body 10, and the hole features 20 in two adjacent columns are staggered with each other. In this way, more hole features 20 can be arranged on the belt body 10 to accommodate materials while ensuring that there is no interference between adjacent materials.

[0040] The hole feature 20 can be a blind hole that does not penetrate the belt body 10 in the thickness direction, or a through hole that penetrates the belt body 10 in the thickness direction. If the particle size of the material is smaller than the thickness of the belt body 10, it is not necessary to make the hole feature 20 penetrate the belt body 10.

[0041] The cross-section of the hole feature 20 can be of various shapes, for example, Figure 2 As shown, it can be a circular hole, such as Figure 3 , Figure 4 As shown, it can be an oblong hole, for example, or it can be an elliptical hole, a polygonal hole, etc.

[0042] If it is an oblong hole or an elliptical hole, based on the requirements for material arrangement, the oblong hole is arranged in a manner that the long diameter is consistent with the conveying direction of the belt body 10, or the oblong hole is arranged in a manner that the long diameter is consistent with the width direction of the belt body 10. For example, if it is required that jujubes are conveyed in a manner that the long diameter is consistent with the conveying direction of the belt body 10, the oblong hole is arranged in a manner that the long diameter is consistent with the conveying direction of the belt body 10; if it is required that jujubes are conveyed in a manner that the long diameter is consistent with the width direction of the belt body 10, the oblong hole is arranged in a manner that the long diameter is consistent with the conveying direction of the belt body 10.

[0043] In some preferred structures, such as Figure 5 As shown, a negative suction platform 30 is provided below the belt body 10 in the area corresponding to the identification mechanism of the visual selection machine, for sucking gas toward the hole feature 20. By sucking gas into the hole feature 20, the material can be adsorbed, so that the material is combined with the hole feature 20 with a certain pre-tightening force, so that the material passes through the identification mechanism in a more stable posture.

[0044] The belt body 10 can be an ordinary non-transparent belt body 10, or a transparent belt body 10. The belt body 10 is configured as a transparent belt body 10 so that the two identification mechanisms can photograph and identify the upper and lower surfaces of the material from the upper and lower directions of the belt body 10.

[0045] In addition, although exemplary embodiments have been described in the present invention, the scope includes any and all embodiments based on the present invention with equivalent elements, modifications, omissions, combinations (e.g., various embodiments intersecting schemes), adaptations or changes. The elements in the claims will be interpreted broadly based on the language adopted in the claims, and are not limited to the examples described in this specification or during the implementation of this application, and the examples will be interpreted as non-exclusive.
