Description

Technical Field

[0001] The utility model relates to the technical field of screening and sieving, in particular to a conveyor belt, a conveyor roller and a conveyor device on a double-sided recognition and 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 has at least the following effects on the positioning and identification of materials when used in the visual selection machine:

[0004] 1. The conveyor belt is prone to lateral deviation or movement, resulting in inaccurate lateral positioning of the material.

[0005] 2. When the conveying device is used in a double-sided recognition visual selection machine and the conveyor belt needs to be configured as a transparent conveyor belt (the double-sided recognition visual selection machine uses at least two sets of recognition mechanisms to face the outer surface and inner surface of the conveyor belt to identify materials, and the lower recognition mechanism needs to identify materials from below the material through the belt body of the conveyor belt), the transparent conveyor belt is in contact with the roller surface of the conveyor roller over the entire width, resulting in a decrease in transparency, which in turn affects the lower recognition mechanism to identify materials from below the material. Utility Model Content

[0006] In view of the above problems existing in the prior art, the purpose of the present invention is to provide a conveyor belt, a conveyor roller and a conveyor device to solve the problems in the prior art.

[0007] In order to achieve the above purpose, the utility model adopts the following scheme.

[0008] A conveyor belt, comprising a belt body, wherein the belt body is configured to be transparent, and the conveyor belt further comprises at least two edge pads; wherein:

[0009] The two edge pads are respectively attached to the side areas on the inner side of the belt body in the width direction, so that the conveyor belt contacts the roller surface of the conveyor roller through the two edge pads, and the belt body has a non-contact area that does not contact the roller surface of the conveyor roller.

[0010] Preferably, the conveyor belt further comprises a middle pad strip, which is attached to the middle portion of the inner side of the belt body in the width direction, so that the conveyor belt contacts the roller surface of the conveyor roller through the middle pad strip and the two edge belt bodies; wherein:

[0011] A positioning strip is formed at the middle portion of the inner side of the middle cushion strip in the width direction, and the positioning strip cooperates with the conveying roller to limit the lateral displacement of the conveying belt.

[0012] Preferably, the cross section of the positioning strip is trapezoidal.

[0013] Preferably, the middle pad and the side pad have the same thickness.

[0014] The utility model also discloses a conveying roller, which is used to cooperate with the above-mentioned conveying belt; wherein:

[0015] A circumferentially extending positioning groove is provided on the outer peripheral surface of the middle area of ​​the conveying roller. When the conveying roller drives the conveying belt to run, the positioning strip of the middle pad strip of the conveying belt cooperates with the positioning groove to limit the lateral displacement of the conveying belt.

[0016] The utility model also discloses a conveying device, comprising the conveying belt and the conveying roller.

[0017] Compared with the prior art, the conveyor belt, conveyor roller and conveyor device provided by the utility model have the following advantages:

[0018] On the one hand, the belt body between the side pads and the middle pads is formed into a non-contact area that does not contact the roller surface of the conveyor roller, so that the transparency of this area will not be affected or will be less affected by the conveyor roller because it will not contact the roller surface of the conveyor roller. Therefore, when the material is conveyed by this part of the area, the identification mechanism below the double-sided visual selection machine can clearly identify the material from below the material through the belt body; on the other hand, when the conveyor roller drives the conveyor belt, the positioning strip on the middle pad of the conveyor belt cooperates with the positioning groove of the conveyor roller to prevent the conveyor belt from moving horizontally during operation, thereby preventing the conveyor belt from lateral movement or deviation.

"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.

[0030] 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.

[0031] The embodiment of the utility model discloses a conveying device, such as Figures 1 to 4 As shown, the conveying device includes a conveying belt and a conveying roller, and the conveying roller is used to drive the conveying belt to operate; the conveying device provided by the utility model is particularly suitable for a double-sided visual selection machine with at least two sets of identification mechanisms.

[0032] Each conveyor belt includes a belt body, two side pads, and a middle pad; the belt body is made of a transparent flexible material, the two side pads are respectively attached and fixed to the two side areas on the inner side of the belt body in the width direction, for example, the side pads can be bonded and fixed to the side areas by a colloid, and the middle pad is attached and fixed to the middle area on the inner side of the belt body in the width direction, and the thickness of the middle pad is substantially equal to that of the side pad; a protruding positioning strip is formed in the middle of the inner side of the middle pad in the width direction, preferably, the positioning strip is integrally formed with the middle pad, and the positioning strip can have a variety of shapes, for example, a rectangular or semicircular cross-section, preferably, the cross-section of the positioning strip is a trapezoid.

[0033] like Figure 3 Combined with Figure 2 As shown, each conveyor roller can drive multiple conveyor belts at the same time. A circumferentially extending positioning groove is provided on the outer peripheral surface of the conveyor roller at the axial position corresponding to the middle area in the width direction of the conveyor belt. The cross-section of the positioning groove matches the cross-section of the positioning strip on the above-mentioned middle pad strip.

[0034] When the conveyor roller rotates to drive the conveyor belt to run, the conveyor belt contacts the roller surface of the conveyor roller with the help of the edge pads and the middle pads arranged on the inner side of the belt body. In this way, the belt body between the edge pads and the middle pads forms a non-contact area that does not contact the roller surface of the conveyor roller. Therefore, the transparency of this area will not be affected or will be less affected by the conveyor roller because it will not contact the roller surface of the conveyor roller. Therefore, by using this part of the area to convey materials, the identification mechanism below the double-sided visual sorting machine can clearly identify the materials from below the materials through the belt body.

[0035] On the other hand, when the conveyor roller drives the conveyor belt, the positioning strip on the middle pad of the conveyor belt cooperates with the positioning groove of the conveyor roller to prevent the conveyor belt from moving laterally during operation, thereby preventing the conveyor belt from moving laterally or deviating.

[0036] 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.
