The direction description in the embodiment, such as "upper", "lower", "top", "bottom", etc., is all with reference to the direction of the product in the actual use scene.

[0045] In this document, reference to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. As those skilled in the art will readily appreciate, the various embodiments described herein can be combined with one another.

[0046] At present, the laser non-destructive scribing machine is a cutting device for solar cell or photovoltaic module. The laser non-destructive scribing machine uses a laser to generate a high-energy laser beam, cuts the sheet material into the required size and shape by instantaneous heating, and realizes the scribing of the solar cell.

[0047] However, when laser scribing is performed, pure water is needed to cool the sheet material, so that the sheet material after scribing will have residual water. If the water on the surface of the sheet material cannot be dried in time, the execution of the next process will be affected.

[0048] To this end, an embodiment of the present application provides a conveying device.

[0049] Figure 1 A schematic structural diagram of the conveying device provided by the present application is shown.

[0050] As shown in Figure 1 , the conveying device comprises a conveying mechanism and a drying mechanism. The conveying mechanism is used for conveying sheet materials, and the drying mechanism is used for drying the sheet materials during the conveying process. Exemplarily, the sheet materials can be battery sheet raw materials such as silicon wafers, and the sheet materials can be processed through a wafer slicing process.

[0051] The conveying mechanism comprises a conveying table 10, a conveying belt 20, a driving assembly 30, a heating assembly 40, and a negative pressure assembly 50. The conveying table 10 is a basic support structure of the conveying mechanism. The conveying belt 20 is arranged on the conveying table 10, and a conveying area 21 is formed above the conveying belt 20. The conveying belt 20 is used for carrying and conveying the sheet materials located in the conveying area 21.

[0052] The driving assembly 30 is arranged on the conveying table 10 and connected to the conveying belt 20. Exemplarily, the sheet materials can be placed on the upper surface of the conveying belt 20. The driving assembly 30 can drive the conveying belt 20 to roll, so as to drive the sheet materials to move.

[0053] The heating assembly 40 is arranged on the conveying table 10 and located below the conveying area 21. The heating assembly 40 is used for increasing the temperature of the conveying area 21. In this way, the evaporation of the moisture on the surface of the sheet materials can be accelerated.

[0054] The drying mechanism comprises a support 60 and a drying assembly 70. The support 60 is used for supporting the drying assembly 70. The drying assembly 70 is connected to the support 60 and arranged above the conveying belt 20, so that the drying assembly 70 is located above the conveying area 21. The drying assembly 70 and the heating assembly 40 are distributed in an up-down manner with respect to the conveying area 21. The drying assembly 70 is used for drying the sheet materials.

[0055] The conveying belt 20 is provided with suction holes 22. The negative pressure assembly 50 is used for sucking the sheet materials through the suction holes 22 when the conveying belt 20 conveys the materials, so that the sheet materials are attached to the conveying belt 20, and the sheet materials are prevented from being separated from the conveying belt 20 during the conveying process.

[0056] When the conveying belt 20 transports the sheet material, the heating assembly 40 can heat the area around the periphery of the sheet material, and the drying assembly 70 can dry the sheet material in the transportation area 21, so that the moisture on the surface of the sheet material can be quickly evaporated, achieving the drying effect. In addition, the heating assembly 40 and the drying assembly 70 can heat and dry the sheet material from below and above, respectively, achieving comprehensive and rapid drying, so that the sheet material can be quickly put into the next process, improving the production efficiency.

[0057] Figure 2 A structural schematic diagram of the drying mechanism provided in the present application is shown.

[0058] As shown in Figure 1 and Figure 2 In some embodiments, the lower part of the support 60 has a receiving space, and the transportation platform 10 is located in the receiving space so that the transportation platform 10 passes through the support 60. The drying assembly 70 is fixed to the upper part of the support 60. In this way, the total occupied space of the support 60 and the transportation platform 10 can be reduced, and the space utilization rate can be improved.

[0059] In some embodiments, the drying assembly 70 includes a heat source 71 and a blowing piece 72. The heat source 71 is arranged on the upper part of the support 60, and the heat source 71 is located above the conveying belt 20, and the heating part of the heat source 71 is arranged downward. The blowing piece 72 is arranged on the upper part of the support 60, and the blowing piece 72 is located on the side of the heat source 71, and the air outlet of the blowing piece 72 is arranged to face the conveying belt 20. For example, the heat source 71 can be an infrared heater, which irradiates the sheet material with infrared rays to increase the surface temperature of the sheet material. The blowing piece 72 can be a wind knife.

[0060] When the conveying belt 20 transports the sheet material, the heat source 71 can heat the sheet material to increase the surface temperature of the sheet material, and at the same time, the blowing piece 72 can blow air to the sheet material to increase the air flow speed on the surface of the sheet material, thereby accelerating the evaporation of the moisture on the surface of the sheet material.

[0061] In some embodiments, the heat source 71 is arranged in a first direction, and the first direction is parallel to the length direction of the conveying belt 20. For example, the first direction is the X-axis direction in the figure. In this way, when the sheet material is transported below the heat source 71, the heat source 71 can continuously heat the sheet material.

[0062] In some embodiments, the heat source 71 has a plurality of heat sources 71, and the plurality of heat sources 71 are distributed in a second direction. The second direction has an included angle with the first direction, for example, the second direction is parallel to the width direction of the conveying belt 20, and the second direction is the Y-axis direction in the figure.

[0063] Exemplarily, the number of the heat sources 71 is 2, and the two heat sources 71 can heat the sheet material at the same time, increase the heating area, and improve the heating uniformity, so as to achieve better drying effect.

[0064] In some embodiments, the blowing pieces 72 are provided in multiple groups, and the blowing pieces 72 in each group are arranged on opposite sides of the heat source 71, so that the heat source 71 is located between the blowing pieces 72 in the multiple groups, and the air outlets of the blowing pieces 72 are obliquely arranged towards the conveying belt 20. In this way, the blowing pieces 72 in the multiple groups can blow air from the two sides of the sheet material respectively, so as to improve the air flow effect.

[0065] In some embodiments, each group of blowing pieces 72 includes a plurality of blowing pieces 72, and the blowing pieces 72 in each group are arranged at intervals along the first direction. Exemplarily, the number of the blowing pieces 72 in each group is 2, and the two blowing pieces 72 are arranged at intervals along the first direction. In this way, when the sheet material is transported below the heat source 71, the blowing pieces 72 can continuously blow air, so as to achieve the effect of overall blowing.

[0066] In some embodiments, the drying assembly 70 further includes a drying temperature measuring piece 73. The drying temperature measuring piece 73 is arranged on the upper portion of the support 60, the drying temperature measuring piece 73 is located above the conveying belt 20, and the detection end of the drying temperature measuring piece 73 is arranged towards the conveying belt 20. Exemplarily, the drying temperature measuring piece 73 can be a non-contact temperature measuring sensor, which can detect the surface temperature of the sheet material and feed back the surface temperature of the sheet material, so as to monitor the surface temperature of the sheet material and achieve better heating effect.

[0067] In some embodiments, the drying temperature measuring piece 73 is provided in multiple numbers, and the multiple drying temperature measuring pieces 73 are arranged at intervals. Exemplarily, the number of the drying temperature measuring pieces 73 is 2, and the two drying temperature measuring pieces 73 are arranged on opposite sides of the heat source 71, and each drying temperature measuring piece 73 is arranged between the two blowing pieces 72 in each group. In this way, the multiple drying temperature measuring pieces 73 can form multiple detection points, so as to reduce the interference caused by the excessively high or low temperature at individual positions, and improve the temperature detection accuracy.

[0068] In some embodiments, the support 60 includes a column 61, a cross bar 62, a first longitudinal bar 63, and a second longitudinal bar 64. The column 61 extends along the vertical direction. The cross bar 62 is arranged at the top end of the column 61, and extends along the second direction. The first longitudinal bar 63 is slidably connected to the cross bar 62 along the second direction, and extends along the first direction. The second longitudinal bar 64 is slidably connected to the column 61 along the vertical direction, and extends along the first direction.

[0069] The heat source 71 is arranged on the first longitudinal rod 63. In this way, as the first longitudinal rod 63 extends along the second direction, the position of the heat source 71 in the second direction can be adjusted, so that the heat source 71 can be directly opposite the sheet-shaped material for drying, improving the drying efficiency and improving the applicability of the heat source 71 to different width drying scenarios.

[0070] The blowing member 72 is rotatably connected to the second longitudinal rod 64, and the rotation axis of the blowing member 72 is parallel to the horizontal direction. In this way, as the second longitudinal rod 64 extends along the first direction, the position of the blowing member 72 in the first direction can be adjusted, and by rotating the blowing member 72, the blowing angle of the blowing member 72 can be adjusted to achieve better drying effect and improve the applicability of the blowing member 72 to different width or height drying scenarios.

[0071] For example, the plurality of columns 61 are distributed on both sides of the transportation table 10, and the lower ends of the plurality of columns 61 form a containing space. In the example of the present application, the columns 61 are four, two of which are distributed on one side of the transportation table 10, and the other two are distributed on the other side of the transportation table 10.

[0072] For example, the plurality of cross rods 62 are distributed along the first direction, and the two ends of the cross rod 62 are respectively connected to the two columns 61 located on both sides of the transportation table 10. In the example of the present application, the number of cross rods 62 is 2, one of which is located at one end of the transportation table 10 and connected to the adjacent two columns 61, and the other is located at the other end of the transportation table 10 and connected to the adjacent two columns 61.

[0073] For example, the number of first longitudinal rods 63 is consistent with the number of heat sources 71, and the two ends of the first longitudinal rod 63 are respectively slidably connected to the cross rod 62 through the first connecting member 65, so that the first longitudinal rod 63 can move along the length direction of the cross rod 62. For example, the number of first longitudinal rods 63 is 2, and the two first longitudinal rods 63 are distributed along the second direction.

[0074] For example, the first connecting member 65 is a bolt pipe clamp, which is fixedly connected to the end of the first longitudinal rod 63 and clamped on the cross rod 62. By adjusting the bolt of the bolt pipe clamp, the clamping tightness of the bolt pipe clamp can be adjusted, when the bolt pipe clamp is loosened, the first longitudinal rod 63 and the bolt pipe clamp can slide along the cross rod 62; when the bolt pipe clamp is tightened, the first longitudinal rod 63, the bolt pipe clamp and the cross rod 62 are fixed.

[0075] For example, the number of second longitudinal rods 64 is the same as the number of sets of blower components 72. Both ends of the second longitudinal rods 64 are slidably connected to the column 61 via second connectors 66, allowing the second longitudinal rods 64 to move along the length of the column 61. For example, there are two second longitudinal rods 64, distributed on both sides of the transport platform 10.

[0076] For example, the second connector 66 is a bolt clamp, which is fixedly connected to the end of the second longitudinal rod 64 and clamps the column 61. The clamping tightness of the bolt clamp can be adjusted by adjusting the bolt. When the bolt clamp is loosened, the second longitudinal rod 64 and the bolt clamp can slide along the column 61; when the bolt clamp is tightened, the second longitudinal rod 64, the bolt clamp and the column 61 are fixed.

[0077] For example, the second longitudinal rod 64 is provided with a fan bracket 67, the number of fan brackets 67 being the same as the number of blower components 72. The fan brackets 67 are bolted to the second longitudinal rod 64, and the blower components 72 are rotatably connected to the fan brackets 67, so that the blower components 72 can rotate with the second longitudinal rod 64. A damping shaft is provided between the blower component 72 and the fan bracket 67, so that the blower component 72 can be positioned at a specified rotation angle.

[0078] For example, the second longitudinal bar 64 is provided with support plates 68. The number of support plates 68 is the same as the number of drying temperature measuring elements 73. One end of the support plate 68 is bolted to the second longitudinal bar 64, and the other end of the support plate 68 extends towards the first longitudinal bar 63. The drying temperature measuring element 73 is bolted to the end of the support plate 68 near the first longitudinal bar 63. In this way, the drying temperature measuring element 73 can be located directly above the transport table 10.

[0079] In the example of this application, multiple wind turbine supports 67 are spaced apart along the length of the second longitudinal bar 64, and support plates 68 are located between multiple wind turbine supports 67 to avoid positional interference between multiple support structures 60 and improve space utilization.

[0080] Figure 3 A schematic diagram of the transport platform with a cover plate provided in this application. Figure 4 This is a schematic diagram illustrating the coordination between the transport platform and the conveyor belt provided in this application.

[0081] like Figure 3 and Figure 4 As shown, in some embodiments, the transport platform 10 is provided with a guide groove 11, which extends along a first direction. A guide strip 23 is provided on the inner side of the conveyor belt 20, which is in close contact with the transport platform 10, and the guide strip 23 is embedded in the guide groove 11.

[0082] Exemplarily, the upper and lower surfaces of the conveying table 10 are provided with guide grooves 11 recessed in the surfaces of the conveying table 10. The conveying table 10 is provided with driving rollers 12 at two ends thereof, and the two ends of the conveying belt 20 are connected to the two driving rollers 12 respectively. The circumferential side of the driving roller 12 is provided with a positioning groove 121 corresponding to the guide groove 11.

[0083] During the movement of the conveying belt 20 relative to the conveying table 10, the guide strips 23 on the inner side of the conveying belt 20 can move in the guide grooves 11 and the positioning grooves 121, thereby guiding the rolling of the conveying belt 20 and preventing the conveying belt 20 from deviating, and improving the conveying stability.

[0084] Figure 5 A structural schematic view of the conveying table provided in the present application is shown. Figure 6 A structural schematic view of the conveying mechanism provided in the present application is shown.

[0085] As shown in Figure 4 , Figure 5 and Figure 6 , in some embodiments, the upper surface of the conveying table 10 is provided with a negative pressure cavity 13, and the cavity opening of the negative pressure cavity 13 is upwardly arranged. The conveying table 10 is further provided with a cover plate 14. The cover plate 14 is arranged on the cavity opening of the negative pressure cavity 13, and the cover plate 14 is provided with air permeation holes 141, is close to the inner side of the conveying table 10, and the air permeation holes 141 can be communicated with the suction holes 22. A negative pressure assembly 50 is connected to the negative pressure cavity 13, and the negative pressure assembly 50 is used for forming negative pressure in the negative pressure cavity 13.

[0086] During the conveying of the sheet material by the conveying belt 20, the negative pressure cavity 13 is formed with negative pressure by the negative pressure assembly 50, and when the part of the conveying belt 20 with the suction holes 22 moves through the cover plate 14, the negative pressure cavity 13 can suck the sheet material on the conveying belt 20 through the air permeation holes 141 and the suction holes 22, so as to make the sheet material adhere to the conveying belt 20, and avoid the sheet material from being separated from the conveying belt 20 due to factors such as shaking and blowing during the conveying process.

[0087] Exemplarily, the negative pressure cavity 13 has a plurality of negative pressure cavities 13, wherein a plurality of negative pressure cavities 13 spaced apart along the second direction form a group, and a plurality of groups of negative pressure cavities 13 are spaced apart along the first direction. In this way, the plurality of negative pressure cavities 13 are divided into a plurality of units, so as to facilitate the regulation of the negative pressure. Correspondingly, the cover plate 14 has a plurality of cover plates 14, wherein a plurality of cover plates 14 spaced apart along the second direction form a group, and a plurality of groups of cover plates 14 are spaced apart along the first direction. In the example of the present application, the negative pressure cavity 13 has a total of six groups, each group has two negative pressure cavities 13, and each negative pressure cavity 13 is configured with a corresponding cover plate 14.

[0088] In some embodiments, the adsorption holes 22 extend along a first direction, and the vent holes 141 extend along a second direction. For example, the conveyor belt 20 is provided with a plurality of adsorption holes 22, which are formed in multiple rows. The multiple rows of adsorption holes 22 are spaced apart along the second direction, and the plurality of adsorption holes 22 in each row are spaced apart along the first direction. Each cover plate 14 is provided with a plurality of vent holes 141, which are spaced apart along the first direction.

[0089] During the movement of the conveyor belt 20, each adsorption hole 22 can pass through multiple air vents 141. In this way, multiple adsorption holes 22 can be cross-matched with multiple air vents 141, which can improve the adsorption stability of sheet materials and thus improve the transportation stability.

[0090] In some embodiments, the upper surface of the transport platform 10 is provided with a mounting groove 15, which communicates with the guide groove 11. A cover plate 14 is disposed in the mounting groove 15 and is bolted to the transport platform 10. Thus, the mounting groove 15 provides space for accommodating and positioning the cover plate 14, facilitating its installation.

[0091] For example, the mounting groove 15 extends entirely along the second direction so that the same mounting groove 15 can accommodate multiple cover plates 14. Specifically, two cover plates 14 of the same group are disposed in the same mounting groove 15, and the opposite sides of the two cover plates 14 are flush with the two side walls of the guide groove 11, so that a guide space 142 corresponding to the guide groove 11 is formed between the two cover plates 14 of the same group, and the guide strip 23 is embedded in the guide space 142.

[0092] In this way, multiple cover plates 14 can work with guide grooves 11 to guide the conveyor belt 20, avoid positional interference between the cover plates 14 and guide strips 23, and improve space utilization.

[0093] like Figure 1 and Figure 3 As shown, in some embodiments, the heating assembly 40 includes a plurality of heating elements 41, all of which are disposed on the transport platform 10 and are spaced apart along a first direction.

[0095] In this way, the conveying table 10 can accommodate the heating element 41 through the heating groove 16, and when the heating element 41 is working, the heating element 41 can increase the overall temperature of the conveying table 10, thereby playing a warming effect under the conveying area 21. In addition, the plurality of heating elements 41 are distributed along the length direction of the conveying table 10 to improve the heating uniformity.

[0096] As shown in Figure 3 and Figure 5 In the examples of the present application, the negative pressure cavity 13 is arranged between the plurality of heating grooves 16, that is, the plurality of groups of negative pressure cavities 13 and the plurality of heating grooves 16 are staggered and spaced apart along the first direction. In this way, space can be left between the two groups of negative pressure cavities 13 for the hollow arrangement of the conveying table 10 to form the heating groove 16, and space can be left between the two heating grooves 16 for the surface recess of the conveying table 10 to form the negative pressure cavity 13, so as to avoid interference between the negative pressure cavity 13 and the heating groove 16, and improve the space utilization.

[0097] In some embodiments, the conveying table 10 is provided with a heating and temperature measuring element 17 arranged at the side of the conveying table 10. The heating and temperature measuring element 17 is used to detect the temperature of the conveying table 10. For example, the heating and temperature measuring element 17 can be a thermocouple. The temperature of the conveying table 10 can be detected by the heating and temperature measuring element 17 and fed back to monitor the temperature of the conveying table 10, thereby achieving better heating effect.

[0099] As shown in Figure 5 , Figure 6 and Figure 7 In some embodiments, the side of the conveying table 10 is provided with a negative pressure pipe head 18 which is communicated with the negative pressure cavity 13. Each negative pressure cavity 13 is provided with a corresponding negative pressure pipe head 18, and the plurality of negative pressure pipe heads 18 are distributed on both sides of the conveying table 10. The negative pressure assembly 50 is connected to the negative pressure pipe head 18 through an air pipe.

[0100] In some embodiments, the negative pressure assembly 50 includes a negative pressure fan 51, a negative pressure main pipe 52 and a plurality of air suction pipe heads 53. The negative pressure main pipe 52 is connected to the air suction port of the negative pressure fan 51, the plurality of air suction pipe heads 53 are respectively connected to the negative pressure main pipe 52, and the plurality of air suction pipe heads 53 are respectively connected to the plurality of negative pressure pipe heads 18 through air pipes. In this way, the plurality of negative pressure pipe heads 18 can be integrated into the negative pressure main pipe 52 for air suction, and the docking between the plurality of negative pressure cavities 13 and the negative pressure assembly 50 is facilitated.

[0103] The driving roller 32 is rotationally connected to the support frame 31, and the conveying belt 20 is arranged around the driving roller 32. The passing roller 33 is rotationally connected to the support frame 31, and the conveying belt 20 is arranged around the passing roller 33. The tension roller 34 is spaced apart from the passing roller 33 along the first direction, and the tension roller 34 is rotationally connected to the support frame 31. The conveying belt 20 is arranged around the tension roller 34, and the tension roller 34 cooperates with the passing roller 33 to tension the conveying belt 20. The rotating driving member 35 is connected to the driving roller 32, and the rotating driving member 35 is used to drive the driving roller 32 to rotate to drive the conveying belt 20 to roll.

[0107] The adjusting member is exemplarily a top screw 37 arranged to extend in the first direction. The top screw 37 is threadedly connected to the support frame 31 and connected to the mounting bearing 36. Thus, by screwing the top screw 37, the top screw 37 is moved in the first direction, thereby adjusting the position of the mounting bearing 36 in the first direction. Specifically, the top screw 37 and the conveyor belt 20 can respectively apply force to the tensioning roller 34 in opposite directions to fix the position of the tensioning roller 34.

[0108] In some embodiments, a heat insulation member 19 is arranged between the support frame 31 and the conveying table 10. The heat insulation member 19 is exemplarily heat insulation bakelite. The conveying table 10 is provided with a recess on each side, and the heat insulation member 19 is embedded and fixed in the recess. The heat insulation member 19 can reduce heat transfer between the conveying table 10 and the support frame 31, preventing the heat of the heating member 41 from directly conducting to the support frame 31 and affecting the operation of the rotating driving member 35.

The first fixed vertical plate 312 and the detachable vertical plate 313 are respectively located on opposite sides of the bottom plate 311 in the second direction.

[0111] In the example of the present application, the support frame 31 further comprises a second fixed vertical plate 314, a first baffle 315 and a second baffle 316.

The second fixed vertical plate 314 is located on the same side of the bottom plate 311 as the detachable vertical plate 313, and the overall plate formed by the second fixed vertical plate 314 and the detachable vertical plate 313 is arranged opposite to the first fixed vertical plate 312.

[0112] The first baffle 315 and the second baffle 316 are spaced apart in the first direction. The first baffle 315 is fixed between the bottom plate 311, the first fixed vertical plate 312 and the detachable vertical plate 313.

[0113] The first fixed vertical plate 312 and the second fixed vertical plate 314 are respectively hingedly fixed to the heat insulation members 19 on both sides of the conveying table 10, so that the support frame 31 is fixed relative to the conveying table 10 as a whole.

[0114] The dismounting vertical plate 313 is detachably fixed to the first baffle 315 through a dismounting member 3131, so that the dismounting vertical plate 313 and the bottom plate 311 are detachably fixed. In the example of the present application, the dismounting member 3131 can be a butterfly bolt. The upper end of the dismounting vertical plate 313 is also detachably fixed to the conveying table 10 through the dismounting member 3131, so as to improve the connection stability between the support frame 31 and the conveying table 10.

[0115] The passing roller 33 and the tension roller 34 are located at the upper part of the accommodating cavity, and the rotating driving member 35 and the driving roller 32 are located at the lower part of the accommodating cavity. One end of the passing roller 33 is connected to the first fixed vertical plate 312 through a rotating bearing, and the other end of the passing roller 33 is connected to the second fixed vertical plate 314 through a rotating bearing. In this way, the first fixed vertical plate 312 and the second fixed vertical plate 314 simultaneously support the passing roller 33.

[0117] As Figure 8 , Figure 9 and Figure 10 shown, the one end of the tension roller 34 is rotatably connected to the first fixed vertical plate 312, and the other end of the tension roller 34 is detachably rotatably connected to the dismounting vertical plate 313. Two mounting bearings 36 at the two ends of the tension roller 34 are respectively defined as a first mounting bearing 361 and a second mounting bearing 362. A tightening screw 37 corresponding to the first mounting bearing 361 is defined as a first tightening screw 371, and a tightening screw 37 corresponding to the second mounting bearing 362 is defined as a second tightening screw 372.

By screwing the first tightening screw 371, the first tightening screw 371 can drive the first mounting bearing 361 to move in the first sliding groove 3121.

[0119] The dismounting vertical plate 313 is provided with a second sliding groove 3132 on the side facing the first fixed vertical plate 312, the second sliding groove 3132 is arranged along the first direction, and the dismounting vertical plate 313 is provided with a second threaded hole, the second threaded hole is communicated with the second sliding groove 3132.

By screwing the second tightening screw 372, the second tightening screw 372 can drive the second mounting bearing 362 to move in the second sliding groove 3132. The tensioning roller 34 is provided with a connecting shaft close to one end of the dismounting vertical plate 313, the connecting shaft is inserted into the inner ring of the second mounting bearing 362.

[0120] As shown in Figure 6 , Figure 8 and Figure 10 , thus, when the dismounting vertical plate 313 is fixed to the bottom plate 311, the first fixed vertical plate 312 cooperates with the dismounting vertical plate 313 to support the tensioning roller 34. When the dismounting vertical plate 313 is dismounted from the bottom plate 311, the dismounting vertical plate 313 opens the accommodation cavity, at this time, the second mounting bearing 362 arranged on the dismounting vertical plate 313 can be separated from the connecting shaft at one end of the tensioning roller 34, so that the conveying belt 20 passing through the tensioning roller 34 can be taken out from the tensioning roller 34, which is convenient for the user to replace and maintain the conveying belt 20.

[0121] It can be understood that after the replacement and maintenance of the conveying belt 20 are completed, the dismounting vertical plate 313 can be reinstalled and fixed, and the inner ring of the second mounting bearing 362 is inserted into the connecting shaft at one end of the tensioning roller 34.

[0122] For example, one end of the driving roller 32 is rotatably connected to the first fixed vertical plate 312 through the outer bearing seat 38, and the other end of the driving roller 32 is rotatably connected to the dismounting vertical plate 313.
