[0030] The following description is used to disclose the present disclosure so that those skilled in the art can implement the present disclosure. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations. The basic principles of the present disclosure defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present disclosure.

[0031] Those skilled in the art should understand that, in the disclosure of the present invention, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0032] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0033] In the present disclosure, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or can communicate with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0034] When the conveyor belt device in the related art is used for conveying, usually multiple conveyor belts are arranged in an aligned manner along the conveying direction to convey materials, but a gap will be formed between two adjacent conveyor belts arranged in this way, and the materials are easily stuck in the above gap when being conveyed along the conveying direction, resulting in interference in the conveying of the materials. In addition, when the conveyor belt device is used to convey materials processed by a preceding device that requires an operating space on one side, for example, when conveying rubber materials output after mixing in an open mill, an operating space must be reserved on the side of the open mill close to the conveyor belt device for manual operation of the open mill. The operating space reserved on one side of the preceding device will make it inconvenient for the conveyor belt device to convey materials later.

[0035] In view of this, the present disclosure provides a conveyor belt device, when the conveyor belt device conveys materials, the materials are unlikely to be stuck, and the conveyor belt device can adapt to the working condition where an operating space needs to be reserved on one side of the previous device, such as the above-mentioned mixing mill.

[0036] The conveyor belt device of the embodiment of the present disclosure is arranged after the front-stage device. Optionally, the front-stage device can be the aforementioned open mill. The open mill can mix the rubber material and improve the mechanical properties of the rubber material. When the open mill is running, an operating space needs to be reserved on one side of the open mill for a person to stand on one side of the open mill to cooperate with the operation of the open mill to perform manual mixing operations such as kneading the rubber material or adding auxiliary materials, so that the open mill can mix the rubber material. The conveyor belt device is used to convey the material processed by the front-stage device, such as the above-mentioned rubber material. However, it can be understood that the materials that can be conveyed by the front-stage device and the conveyor belt device of the embodiment of the present disclosure include but are not limited to these, and other processing devices that need to reserve an operating space on one side and the materials formed by their processing can also be conveyed by the conveyor belt device of the present disclosure.

[0037] Figure 1 It is a schematic structural diagram of a conveyor belt device according to an embodiment of the present disclosure. Figure 2 is a cross-sectional schematic diagram of a conveyor belt device according to an embodiment of the present disclosure. Figure 1 and Figure 2 The conveyor belt device of the embodiment of the present disclosure includes a first conveyor frame 10, a second conveyor frame 20, a first transmission shaft 30, a second transmission shaft 40 and an endless conveyor belt 50.

[0038] The second conveyor frame 20 is arranged close to the preceding device relative to the first conveyor frame 10, that is, the second conveyor frame 20 is arranged upstream of the first conveyor frame 10. When the material output by the preceding device is conveyed, the material first passes through the second conveyor frame 20 and then passes through the first conveyor frame 10. The second conveyor frame 20 is swingably connected to the first conveyor frame 10 between a conveying position and an operating position.

[0039] Figure 3 FIG. 2 is a schematic diagram of the second conveying frame 20 of the embodiment of the present disclosure when it is located at the conveying position. Figure 3 When the second conveying frame 20 is in the conveying position, it is aligned with the first conveying frame 10 along the conveying direction.

[0040] Figure 4 FIG. 2 is a schematic diagram of the second conveying rack 20 of the embodiment of the present disclosure when it is in the operating position. Figure 4 When the second conveying rack 20 is in the operating position, an operating space 201 of the preceding-stage device is formed between the second conveying rack 20 and the preceding-stage device.

[0041] Optionally, the first conveying frame 10 is provided with a swing shaft 11 , and the second conveying frame 20 is connected to the first conveying frame 10 so as to be swingable around the swing shaft 11 .

[0042] Optionally, the swing of the second conveying frame 20 can be driven by a swing driving member 12. The swing driving member 12 is configured as a telescopic driving member, which is connected to the second conveying frame 20 to drive the second conveying frame 20 to swing when it is extended. Specifically, the telescopic driving member is configured as a cylinder, which is connected to the second conveying frame 20 to drive the second conveying frame 20 to swing upward when it is extended, and to drive the second conveying frame 20 to swing downward when it is shortened.

[0043] Therefore, before the preceding device is operated, when an operating space 201 needs to be reserved on one side of the preceding device, the second conveyor frame 20 swings to the operating position, thereby avoiding the operating space 201. When the preceding device outputs processed materials, the second conveyor frame 20 can swing to a position aligned with the first conveyor frame 10 along the conveying direction, so as to facilitate the subsequent conveying of materials.

[0044] See also Figure 2 The first transmission shaft 30 is rotatably disposed on the first conveying frame 10. The second transmission shaft 40 is rotatably disposed on the second conveying frame 20. The annular conveyor belt 50 is sleeved outside the first transmission shaft 30 and the second transmission shaft 40 for conveying along the conveying direction.

[0045] Therefore, when the second conveying frame 20 is located at the conveying position and the first transmission shaft 30 and the second transmission shaft 40 rotate, the annular conveyor belt 50 can convey the material along the conveying direction, that is, the length direction of the annular conveyor belt 50, and in the above process, since the material is conveyed on the annular conveyor belt 50, the material is conveyed smoothly and is unlikely to get stuck during the conveying process.

[0046] Optionally, see Figure 1 and Figure 2 The conveyor belt device further includes a conveying drive assembly 60. The conveying drive assembly 60 includes a motor 61 and a driving wheel 62. The driving wheel 62 is rotatably disposed on the first conveying frame 10, and the driving wheel 62 is drivingly connected to the endless conveyor belt 50, the first transmission shaft 30 or the second transmission shaft 40, so as to drive the endless conveyor belt 50 to go around under the drive of the motor 61 for conveying.

[0047] In some examples, the driving wheel 62 is sleeved inside the endless conveyor belt 50 to drive the endless conveyor belt 50 to move around under the drive of the motor 61 .

[0048] In other examples, the driving wheel 62 is connected to the first transmission shaft 30 or the second transmission shaft 40 to drive the first transmission shaft 30 or the second transmission shaft 40 to rotate under the drive of the motor 61, and the rotation of the first transmission shaft 30 or the second transmission shaft 40 drives the circular conveyor belt 50 to revolve.

[0049] Therefore, when the motor 61 drives the driving wheel 62 to rotate, the rotation of the driving wheel 62 will drive the annular conveyor belt 50 to orbit along the circumference of the annular conveyor belt 50, so that the annular conveyor belt 50 drives the material to move along the conveying direction, so that the material is conveyed.

[0050] Optionally, see Figure 2 , the conveying drive assembly 60 further includes a first guide wheel 63 and / or a second guide wheel 64. The first guide wheel 63 is arranged between the driving wheel 62 and the first transmission shaft 30, and is located outside the endless conveyor belt 50, and is passed around by the endless conveyor belt 50. The second guide wheel 64 is arranged between the driving wheel 62 and the second transmission shaft 40, and is located outside the endless conveyor belt 50, and is passed around by the endless conveyor belt 50. Thus, the first guide wheel 63 can play a guiding, pulling and tensioning role between the first transmission shaft 30 and the driving wheel 62, and the second guide wheel 64 can play a guiding, pulling and tensioning role between the second transmission shaft 40 and the driving wheel 62, ensuring that the endless conveyor belt 50 can be smoothly passed around and is difficult to be loosened when passing around, and the overall structure is compact and occupies little space.

[0051] More preferably, the first guide wheel 63 and the second guide wheel 64 are arranged opposite to each other. Thus, the cooperation between the first guide wheel 63 and the second guide wheel 64 can play a role of clamping and limiting the endless conveyor belt 50, which is conducive to ensuring the stable operation of the endless conveyor belt 50 when it is circling.

[0052] Optionally, see Figure 1 The conveying drive assembly 60 further includes a driving wheel 65 and an annular transmission belt 66. The driving wheel 65 is rotatably disposed on the first conveying frame 10 and is connected to the motor 61. The annular transmission belt 66 is sleeved outside the driving wheel 65 and the driving wheel 62 to drive the driving wheel 62 to rotate under the drive of the motor 61. Therefore, when the motor 61 drives the driving wheel 65 to rotate, the driving wheel 65 drives the annular transmission belt 66 to go around, so that the annular transmission belt 66 drives the driving wheel 62 to rotate.

[0053] In some examples, when the material conveyed by the conveyor belt device is a sheet or strip material, for example, when the material conveyed by the conveyor belt device is a rubber strip and / or film formed after mixing and cutting in an open mixer, the conveyor belt device further includes a guide limiter 70. The guide limiter 70 is arranged at the input end of the endless conveyor belt 50, and forms at least one guide limiter opening 701, and the guide limiter opening 701 allows sheet and / or strip materials of a predetermined width to pass through in a predetermined posture. Thus, the guide limiter 70 can guide and limit sheet and / or strip materials whose width is less than or equal to the guide limiter opening 701, and can allow the sheet and / or strip materials to be introduced into the endless conveyor belt 50 in a manner in which the length direction is parallel or inclined to the conveying direction of the endless conveyor belt 50, and be conveyed away in this posture.

[0054] Specifically, there are a plurality of guide limit openings 701, and the plurality of guide limit openings 701 are arranged at intervals along the width direction of the endless conveyor belt 50. It is understandable that the number and diameter of the guide limit openings 701 can be adaptively adjusted as needed.

[0055] Optionally, the guide limiter 70 includes a plurality of guide rollers 71. The plurality of guide rollers 71 are arranged at intervals along the width direction of the endless conveyor belt 50 to form a plurality of guide limit openings 701.

[0056] In some examples, when the preceding device is an open mixing mill, the material conveyed by the conveyor belt device is a rubber material, and the conveying direction is an inclined direction from bottom to top, the conveyor belt device further includes a rubber pressing member 80. The rubber pressing member 80 is disposed on the first conveyor frame 10 or the second conveyor frame 20, and the rubber pressing member 80 is disposed above the endless conveyor belt 50 at intervals. Thus, when the rubber material is conveyed by the endless conveyor belt 50, the rubber pressing member 80 can apply pressure to press the rubber material down on the endless conveyor belt 50, increase the contact area between the endless conveyor belt 50 and the rubber material, and improve the adhesion of the rubber material to the endless conveyor belt 50, so that when the endless conveyor belt 50 conveys the rubber material in a direction from bottom to top, the rubber material is difficult to slide off the endless conveyor belt 50, ensuring that the endless conveyor belt 50 can smoothly convey the rubber material.

[0057] Optionally, the rubber pressing member 80 can be turned upside down and arranged on the first conveying frame 10 or the second conveying frame 20. Therefore, when the endless conveyor belt 50 conveys rubber materials of different thicknesses, the rubber pressing member 80 can be turned upside down to increase the distance between the rubber pressing member 80 and the endless conveyor belt 50, or turned downside down to reduce the distance between the rubber pressing member 80 and the endless conveyor belt 50. Different distances can adapt to rubber materials of different thicknesses, so that the rubber pressing member 80 can exert downward pressure on rubber materials of different thicknesses, so that the rubber materials of different thicknesses can increase the adhesion force of the rubber materials attached to the endless conveyor belt 50.

[0058] Optionally, a flip shaft 21 is provided on the first conveyor frame 10 or the second conveyor frame 20. The glue pressing member 80 includes a glue pressing roller 82 and at least one flip arm 81. The flip arm 81 is disposed on the flip shaft 21 so as to be flippable up and down. The glue pressing roller 82 extends along the width direction of the endless conveyor belt 50, and is connected to the flip arm 81 so as to flip along with the flip arm 81. Specifically, there are two flip arms 81, and the two flip arms 81 are respectively connected to opposite ends of the glue pressing roller 82, and are respectively connected to the flip shaft 21.

[0059] Optionally, the rubber pressing roller 82 is rotatably disposed on the flip arm 81. Therefore, when the rubber pressing roller 82 applies downward pressure to the rubber material so that the rubber material being transported is closely attached to the endless conveyor belt 50, and the endless conveyor belt 50 can continue to transport the rubber material, the rubber pressing roller 82 can rotate so that the rubber material can be smoothly transported away from under the rubber pressing roller 82, thereby ensuring smooth transportation of the rubber material.

[0060] The present disclosure also provides an open mill system, which includes an open mill and the above-mentioned conveyor belt device. The conveyor belt device is arranged downstream of the open mill and is used to convey the rubber material mixed in the open mill away.

[0061] Optionally, the open mill system further comprises a subsequent device, which is arranged downstream of the conveyor belt device and is used to receive the rubber material conveyed by the conveyor belt device.

[0062] Specifically, the subsequent device may be another open mill, which is used to further mix and process the rubber material conveyed by the conveyor belt device.

[0063] It should be understood by those skilled in the art that the embodiments of the present disclosure described above and shown in the accompanying drawings are only examples and do not limit the present disclosure. The advantages of the present disclosure have been fully and effectively realized. The functions and structural principles of the present disclosure have been demonstrated and explained in the embodiments, and the embodiments of the present disclosure may be deformed or modified in any way without departing from the principles.
