[0028] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and do not limit the utility model.

[0029] As shown in Figure 1 and Figure 2 In an embodiment, the synchronous belt conveying device 10 comprises a support assembly 1, a synchronous belt transmission assembly 2, a connecting assembly 3 and a driving assembly 4. The synchronous belt transmission assembly 2 is connected to the support assembly 1. The synchronous belt transmission assembly 2 comprises a driving wheel 21, a driven wheel 22 and a synchronous belt 23. The driving assembly 4 is connected to the support assembly 1 and connected to the driving wheel 21. The driving assembly 4 is used to drive the driving wheel 21 to rotate about its own axis. That is, the driving assembly 4 can provide driving force to the driving wheel 21, so that the driving wheel 21 can rotate about its own axis. The driven wheel 22 is connected to the support assembly 1 through the connecting assembly 3 and can rotate about its own axis relative to the support assembly 1. The synchronous belt 23 is arranged around and engaged with the driving wheel 21 and the driven wheel 22. The connecting assembly 3 is used to adjust the driven wheel 22 to loosen or tension the synchronous belt 23.

[0030] The synchronous belt 23 is sleeved and engaged with the driving wheel 21 and the driven wheel 22, which means that the synchronous belt 23 is sleeved on the outside of the driving wheel 21 and the outside of the driven wheel 22, and the synchronous belt 23 is engaged with the driving wheel 21 and the driven wheel 22.

[0031] When the driving assembly 4 drives the driving wheel 21, the driving wheel 21 can drive the synchronous belt 23 to rotate, and in turn drive the driven wheel 22 to rotate through the synchronous belt 23. When the synchronous belt 23 rotates, it can convey the material placed on the synchronous belt 23, so that the material can be conveyed by the synchronous belt conveying device 10.

[0032] In this embodiment, when the material is conveyed by the synchronous belt conveying device 10, the driving wheel 21 and the driven wheel 22 can tension the synchronous belt 23. When it is necessary to replace the synchronous belt 23, the driven wheel 22 can be adjusted to loosen the synchronous belt 23, so that the synchronous belt 23 can be conveniently taken off from the driving wheel 21 and the driven wheel 22. After the new synchronous belt 23 is sleeved on the driving wheel 21 and the driven wheel 22, the driven wheel 22 can be adjusted again to tension the synchronous belt 23.

[0033] It should be understood that the driving wheel 21 and the driven wheel 22 are synchronous wheels, and the driving wheel 21 and the driven wheel 22 are different shafts, and the axes of the driving wheel 21 and the driven wheel 22 are not perpendicular. In addition, the axes of the driving wheel 21 and the driven wheel 22 can be parallel, and the two are spaced apart in the radial direction of the driving wheel 21.

[0034] In addition, the driving assembly 4 can be connected to the support assembly 1, and after the driving wheel 21 is connected to the driving assembly 4, in addition to being able to rotate around its own axis, it can not produce other movements relative to the support assembly 1. For example, the driving assembly 4 can include a rotating motor, at this time, the shell of the rotating motor is fixed to the support assembly 1, the motor shaft of the rotating motor is connected with the driving wheel 21, and the motor shaft is coaxially arranged with the driving wheel 21. When the motor shaft rotates, the driving wheel 21 can be driven to rotate around its own axis. In addition, the driving assembly 4 can also include a speed reducer, at this time the motor shaft is connected with the input shaft of the speed reducer, and the output shaft of the speed reducer is connected with the driving wheel 21. When working, the torque of the rotating motor is first transmitted to the speed reducer, and then transmitted from the speed reducer to the driving wheel 21.

[0035] In an embodiment, the connecting assembly 3 can be switched between a first state and a second state; when the connecting assembly 3 is in the first state, the distance between the driving wheel 21 and the driven wheel 22 is fixed; when the connecting assembly 3 is in the second state, the driven wheel 22 can approach or move away from the driving wheel 21 to loosen or tighten the synchronous belt 23; and after the driven wheel 22 approaches or moves away from the driving wheel 21, the connecting assembly 3 can be switched to the first state to keep the distance between the driving wheel 21 and the driven wheel 22 fixed, so that the distance between the driving wheel 21 and the driven wheel 22 can be kept at the adjusted distance.

[0036] That is, in the present embodiment, the connecting assembly 3 adjusts the driven wheel 22 by locking or loosening the driven wheel 22. Specifically, when the connecting assembly 3 is in the first state, the driven wheel 22 is locked; when the connecting assembly 3 is in the second state, the driven wheel 22 is loosened.

[0037] When the material needs to be conveyed by the synchronous belt conveying device 10, the connecting assembly 3 is switched to the first state, so that the distance between the driven wheel 22 and the driving wheel 21 is fixed, so that the synchronous belt 23 can be kept in tension. When the synchronous belt 23 needs to be replaced, the connecting assembly 3 can be switched to the second state, at this time, the driven wheel 22 can be moved close to the driving wheel 21 to loosen the synchronous belt 23, so that the synchronous belt 23 can be conveniently taken off from the driving wheel 21 and the driven wheel 22. After the new synchronous belt 23 is sleeved on the driving wheel 21 and the driven wheel 22, the driven wheel 22 can be moved away from the driving wheel 21 to tension the synchronous belt 23, and then the connecting assembly 3 is switched to the first state, so that the distance between the driving wheel 21 and the driven wheel 22 can be kept at the adjusted size, and the synchronous belt 23 can be kept in tension.

[0038] In addition, the distance between the driving wheel 21 and the driven wheel 22 can refer to the maximum distance, the minimum distance or the average distance between the two. Moreover, the distance between the driving wheel 21 and the driven wheel 22 can also refer to the distance between the axes of the two.

[0039] It should be understood that when the connecting assembly 3 is in the first state, the driven wheel 22 can not produce other movements relative to the support assembly 1 except that it can rotate around its own axis relative to the support assembly 1. Of course, when the connecting assembly 3 is in the first state, the driven wheel 22 can also be able to produce other movements relative to the support assembly 1 except that it can rotate around its own axis relative to the support assembly 1, as long as the distance between the driving wheel 21 and the driven wheel 22 can be kept unchanged during the process, for example, the driven wheel 22 can move around the axis of the driving wheel 21 relative to the support assembly 1 in addition to being able to rotate around its own axis relative to the support assembly 1.

[0040] As shown in Figure 1 and Figure 2 In an embodiment, the support assembly 1 is provided with a connecting hole 11; the connecting assembly 3 includes a locking piece 31 and a locking nut 32, the locking piece 31 is connected to the connecting hole 11 and penetrates the driven wheel 22; the locking nut 32 is threadedly matched with the locking piece 31; when the connecting assembly 3 is in the first state, the locking piece 31 and the locking nut 32 press the driven wheel 22 on the support assembly 1; when the connecting assembly 3 is in the second state, the locking piece 31 and the locking nut 32 loosen the driven wheel 22 and the support assembly 1, and the locking piece 31 can move close to or away from the driving wheel 21. In this way, the support assembly 1 can be conveniently switched between the first state and the second state, so that the synchronous belt 23 can be conveniently replaced.

[0041] As shown in Figure 1 and Figure 2As shown, in an embodiment, the support assembly 1 comprises a support plate 12, the connecting hole 11 is arranged on the support plate 12 and penetrates the support plate 12 along the axis of the driven wheel 22; the locking member 31 comprises a stud 311 and a stopper 312, the stud 311 is arranged in the connecting hole 11, and the stopper 312 is connected to the stud 311 and located on the side of the support plate 12 away from the driven wheel 22; the locking nut 32 is located on the side of the driven wheel 22 away from the support plate 12.

[0042] When the connecting assembly 3 is in the first state, the locking nut 32 presses the driven wheel 22 against the support plate 12, at this time, the stopper 312 abuts against the support plate 12, and the stopper 312 and the locking nut 32 press the driven wheel 22 and the support plate 12 together, and the stopper 312, the support plate 12, the driven wheel 22 and the locking nut 32 abut against each other in turn. Thus, the locking member 31 and the driven wheel 22 are prevented from moving relative to the support plate 12, so that the distance between the driving wheel 21 and the driven wheel 22 can be kept fixed.

[0043] When the connecting assembly 3 is in the second state, any two of the stopper 312, the support plate 12, the driven wheel 22 and the locking nut 32 can not abut against each other, so that the stud 311 can move in the connecting hole 11 to drive the stopper 312, the support plate 12, the driven wheel 22 and the locking nut 32 to move closer to or away from the driving wheel 21 at the same time.

[0044] In the embodiment, the connecting hole 11 is arranged to penetrate the support plate 12, which facilitates the cooperation of the support plate 12 with the connecting assembly 3 and the driven wheel 22, thereby facilitating the replacement of the synchronous belt 23.

[0045] In an embodiment, the stud 311 and the stopper 312 are in an integrated structure, at this time, they can constitute a bolt. Of course, in other embodiments, the stopper 312 can also be a nut which is threadedly connected to the stud 311.

[0046] In an embodiment, the connecting hole 11 is an elongated hole which extends along the arrangement direction of the driving wheel 21 and the driven wheel 22. The stud 311 can move in the connecting hole 11 along the length direction of the connecting hole 11.

[0047] In an embodiment, the driving assembly 4 can also be connected to the support plate 12. Moreover, in the axial direction of the driving wheel 21, the driving wheel 21 and the driven wheel 22 are located on the same side of the support plate 12, and the driving assembly 4 can be connected to the side of the support plate 12 away from the driven wheel 22, at this time, the support plate 12 can be provided with an avoiding hole which penetrates the support plate 12, and the driving shaft (such as the motor shaft of a motor or the output shaft of a speed reducer) of the driving assembly 4 can pass through the support plate 12 from the avoiding hole and be connected to the driving wheel 21.

[0048] AsFigure 2 As shown in the figure, in an embodiment, the driven wheel 22 comprises a fixed part 221 and a rotating part 222, the fixed part 221 is sleeved on the locking piece 31, and the locking piece 31 and the locking nut 32 can press the fixed part 221 on the support assembly 1; the rotating part 222 is sleeved on the fixed part 221 and can rotate relative to the fixed part 221 around the axis of the driven wheel 22; the synchronous belt 23 is wound on the rotating part 222 and engages with the rotating part 222.

[0049] Wherein, the rotation of the driven wheel 22 around its own axis means the rotation of the movable part around its own axis. The axis of the driven wheel 22 is the axis of the movable part. The pressing of the locking piece 31 and the locking nut 32 on the driven wheel 22 on the support assembly 1 actually means the pressing of the fixed part 221 on the support assembly 1.

[0050] In addition, the fixed part 221 and the rotating part 222 can both be circular ring structures, and they can be coaxially arranged, and a bearing can be arranged between them. Moreover, the driven wheel 22 can be designed by using an existing synchronous wheel.

After assembly, the driving wheel 21 and the two driven wheels 22 are all located in the synchronous belt 23 and engage with the synchronous belt 23. The two driven wheels 22 can adjust and fix the distance between them and the driving wheel 21 through the connecting assemblies 3 connected thereto, so that the synchronous belt 23 can be adjusted from both ends of the synchronous belt transmission assembly 2 to loosen and tension.

[0052] As shown in the figure, Figure 1 In an embodiment, multiple synchronous belt transmission assemblies 2 are provided, and each synchronous belt transmission assembly 2 is arranged along the axial direction of the driving wheel 21; the multiple synchronous belt transmission assemblies 2 have a first assembly 24 and at least one second assembly 25; the synchronous belt conveying device 10 further comprises a connecting shaft 5 and a shaft coupling 6; the driving wheel 21 of the first assembly 24 is connected to the driving assembly 4; the driving wheel 21 of each second assembly 25 is connected to the connecting shaft 5; the shaft coupling 6 connects the connecting shaft 5 and the driving assembly 4 and is located between the driving wheel 21 of the first assembly 24 and the connecting shaft 5; the connecting shaft 5 is detachably connected to the support assembly 1. In this way, when conveying materials, each synchronous belt transmission assembly 2 can support the materials, thereby improving the support effect on the materials.

[0053] Wherein, "multiple" means more than or equal to two, and the meaning of the word "multiple" in each embodiment is the same. In addition, the first assembly 24 and the second assembly 25 are both synchronous belt transmission assemblies 2.

[0054] When it is necessary to replace the timing belt 23 of the first component 24, the coupling 6 can be disassembled and the distance between the driven pulley 22 and the driving pulley 21 of the first component 24 can be adjusted to loosen the timing belt 23 of the first component 24, and then the timing belt 23 of the first component 24 can be removed.
