[0028] The utility model provides a conveying device for conveying objects, and in the process of conveying objects, it can prevent the objects from being caught in the joint gap of the conveying track 10, thereby ensuring smooth transmission. Specifically, Figure 1 , Figure 2 and Figure 4 As shown, the conveying device is formed by splicing at least two sections of conveying tracks 10, each section of the conveying track 10 includes an input end 10a and an output end 10b, the height of the input end 10a in the horizontal direction is lower than the height of the output end 10b, and the two sections of conveying tracks 10 are spliced along the transmission direction, wherein the output end 10b of the previous section of the conveying track 10 is located above the input end 10a of the next section of the conveying track 10, and the splicing is staggered. In this way, there is no horizontal gap between the two adjacent sections of the conveying track 10, and when the object is transmitted to the splicing position, it falls from the previous section of the conveying track 10 to the next section of the conveying track 10, and the object will not be rolled into the gap. The conveying device of this embodiment can prevent objects from being caught in the splicing gap, so that the transmission is smooth.
[0029] In this embodiment, the splicing methods of the adjacent two ends of the transmission track 10 include but are not limited to the following two:
[0030] In one implementation, the output end 10b of the previous section of the conveying track 10 is located above the input end 10a of the next section of the conveying track 10, so that the conveying surface of the conveying track 10 is inclined. Optionally, the projections of the output end 10b of the previous section of the conveying track 10 and the input end 10a of the next section of the conveying track 10 in the vertical direction partially overlap, so that the two conveying tracks 10 are compactly spliced. Alternatively, optionally, the end faces of the output end 10b of the previous section of the conveying track 10 and the input end 10a of the next section of the conveying track 10 are in the same vertical direction.
[0031] The implementation method has a simple structure and is easy to install.
[0032] In another possible implementation, Figure 2 As shown, the output end 10b of the conveying track 10 is provided with a first avoidance space, and the first avoidance space is located at the bottom of the output end 10b. The input end 10a of the adjacent conveying track 10 can be embedded in the first avoidance space to realize splicing the next section of the conveying track 10 on the output end 10b of the previous section of the conveying track 10.
[0033] In this implementation, an avoidance space is set at the output end 10b of the conveying track 10 for the adjacent conveying track 10 to be embedded, thereby achieving compact splicing, realizing the vertical misalignment between adjacent conveying tracks 10, and avoiding an increase in the overall height of the conveying track 10.
[0034] Alternatively, in one possible implementation, the input end 10a of the conveying track 10 is provided with a second avoidance space, and the second avoidance space is located at the top of the input end 10a. The output end 10b of the adjacent conveying track 10 can be overlapped on the second avoidance space to achieve splicing of the previous section of the conveying track 10 on the input end 10a of the next section of the conveying track 10.
[0035] In this implementation, an avoidance space is set at the input end 10a of the conveying track 10 for the adjacent conveying track 10 to be embedded, thereby achieving compact splicing, realizing the vertical misalignment between adjacent conveying tracks 10, and avoiding an increase in the overall height of the conveying track 10.
[0036] Alternatively, in one possible implementation, a first avoidance space is provided at the bottom of the output end 10b, a second avoidance space is provided at the top of the input end 10a, the input end 10a of the latter section of the conveying track 10 is embedded in the second avoidance space of the output end 10b of the former section of the conveying track 10, and the output end 10b of the former section of the conveying track 10 is embedded in the first avoidance space of the input end 10a of the latter section of the conveying track 10. The output end 10b and the input end 10a of the adjacent conveying tracks 10 are vertically staggered, and the embedded staggered arrangement does not increase the overall height of the conveying track 10, and the compact layout is achieved, and multiple sections of the conveying track 10 are compactly spliced and compact in appearance.
[0037] Optionally, the above-mentioned conveying track 10 can be implemented by the following structure.
[0038] As an optional embodiment, reference Figure 2 and Figure 4The conveying track 10 includes a first conveying shaft 11, a second conveying shaft 12 and a conveyor belt 15. The conveyor belt 15 is arranged on the first conveying shaft 11 and the second conveying shaft 12. The conveyor belt 15 moves on the first conveying shaft 11 and the second conveying shaft 12 to realize the conveying, and then realizes the conveying of objects on the conveyor belt 15. In this embodiment, the first conveying shaft 11 is located at the input end 10a, and the second conveying shaft 12 is located at the output end 10b, that is, the end of the conveyor belt 15 corresponding to the first conveying shaft 11 is the input end 10a, and the end of the conveyor belt 15 corresponding to the second conveying shaft 12 is the output end 10b. The object enters from the input end 10a and falls onto the conveyor belt 15, and is conveyed to the output end 10b by the conveyor belt 15. The object is outputted from the output end 10b, so that the object leaves the conveyor belt 15.
[0039] Based on the structure of the transmission track 10, the output end 10b is higher than the input end 10a in the horizontal direction, including but not limited to the following methods:
[0040] In one possible implementation, the diameter of the second conveyor shaft 12 is greater than the diameter of the first conveyor shaft 11, the conveyor belt 15 is sleeved on the first conveyor shaft 11 and the second conveyor shaft 12, and the conveying surface of the conveyor belt 15 is inclined so that the output end 10b is higher than the input end 10a in the horizontal direction.
[0041] When the object is transferred from the input end 10a to the output end 10b, it falls from the output end 10b into the input end 10a of the next transfer track 10.
[0042] This implementation method has a simple structure.
[0043] As in another possible implementation, the diameters of the first transmission shaft 11 and the second transmission shaft 12 are the same, and by setting the first transmission shaft 11 and the second transmission shaft 12 at different fixed positions, the output end 10b is horizontally higher than the input end 10a. For example, the height of the axis of the second transmission shaft 12 in the horizontal direction is higher than the axis of the first transmission shaft 11, so that the height of the output end 10b in the horizontal direction is higher than the height of the input end 10a. It can be seen that in this implementation, the inclination angle of the transmission surface of the conveyor belt 15 can be determined according to the installation positions of the first transmission shaft 11 and the second transmission shaft 12.
[0044] Compared with the above implementation, the first transmission shaft 11 and the second transmission shaft 12 can be set as the same shaft in this implementation, which can reduce the cost of setting a large diameter shaft, and can reduce the diameter of the transmission shaft to reduce the overall height of the transmission track 10. In addition, this implementation adjusts the installation position of the second transmission shaft 12 and the inclination angle of the transmission surface of the transmission track 10, so as to adjust the inclination angle according to the length of the transmission track 10 to adapt to the requirements of transmission tracks 10 of different lengths.
[0045] Optionally, for a conveying device in the form of a conveyor belt 15, a first avoidance space can be set at the bottom of the output end 10b in the following manner: the conveying track 10 also includes a first idler wheel 14, the first idler wheel 14 is set between the second conveying shaft 12 and the first conveying shaft 11, close to the second conveying shaft 12, the first idler wheel 14 is set at the bottom of the output end 10b, and is located below the conveyor belt 15, the first idler wheel 14 changes the position of the conveyor belt 15 at the output end, so that the conveyor belt 15 at the bottom of the output end 10b avoids to form a first avoidance space. In this way, the input end 10a of the next section of the conveying track 10 is embedded in the first avoidance space and is not affected by the conveyor belt 15.
[0046] Optionally, the conveying track 10 further includes two baffles 16, which are arranged on both sides of the conveying direction of the conveyor belt 15. The first conveying shaft 11 and the second conveying shaft 12 are both mounted on the baffles 16 and are located at different positions of the baffles 16. The baffle 16 is provided with a first notch on one side of the output end 10b, forming a first escape space at the output end 10b; the baffle 16 is provided with a second notch at one end of the input end 10a, forming a second escape space at the input end 10a. The first notch faces downward, and the second notch faces upward, so that the first escape space is formed at the bottom of the output end 10b and the second escape space is formed at the top of the input end 10a.
[0047] Optionally, the conveyor track 10 further includes a flat belt support plate 17, which is located in the middle of the conveyor belt 15 and is used to support the conveying surface of the conveyor belt 15. Optionally, the conveyor belt 15 is a flat belt, and the flat belt support plate 17 is provided to support the conveyor belt 15, so that the conveying surface of the conveyor belt 15 is relatively stable. When applied to an embodiment in which the conveyor track 10 is longer, the flat belt support plate 17 provides support for the conveyor belt 15 to prevent the conveyor belt 15 from being concave in the middle due to the influence of gravity, thereby affecting the normal conveyance of objects.
[0048] Optionally, see Figure 5 In this embodiment, the inclination angle of the conveying surface between the input end 10a and the output end 10b is greater than 0 degrees and less than 45 degrees, and the inclination angle is selected according to the conveying length of the conveying device. In an optional embodiment, the inclination angle is preferably close to 1 degree.
[0049] Optionally, see Figure 1 , Figure 3 and Figure 4In this embodiment, at least one of the first conveying shaft 11 and the second conveying shaft 12 may be a driving shaft 13. Another driving shaft 13 may be provided to drive the conveyor belt 15 to move. For example, the conveying track 10 further includes a driving shaft 13, the driving shaft 13 is located between the first conveying shaft 11 and the second conveying shaft 12, the belt is installed on the first conveying shaft 11, the second conveying shaft 12 and the driving shaft 13, and the driving shaft 13 drives the conveyor belt 15 to move between the first conveying shaft 11 and the second conveying shaft 12 to achieve conveying objects.
[0050] The conveyor belt 15 is driven to move by the driving shaft 13 so that the conveyor belt 15 can move smoothly.
[0051] Optionally, the drive shaft 13 is driven by a drive assembly 20, which includes a motor 21, a motor fixing plate 22 and a synchronous pulley 23 assembly (a synchronous pulley 23 and a synchronous belt 24). The motor 21 is mounted on the motor fixing plate 22, and the output shaft of the motor 21 is connected to the synchronous pulley 23 assembly, and the synchronous pulley 23 assembly is connected to the drive shaft 13. The motor 21 drives the drive shaft 13 to rotate via the synchronous pulley 23 assembly.
[0052] Optionally, see Figure 1 and Figure 3 In this embodiment, the conveying track 10 also includes at least one second idler wheel 18, which is arranged near the driving shaft 13. The second idler wheel 18 is used to increase the contact area between the conveyor belt 15 and the driving shaft 13, increase the friction between the conveyor belt 15 and the driving shaft 13, thereby increasing the moving force of the conveyor belt 15, avoiding the conveyor belt 15 from slipping, and improving the stability of the conveyor belt 15.
[0053] Optionally, two second idler wheels 18 are included, and the two second idler wheels 18 are respectively located on both sides of the axis of the drive shaft 13, and the two second idler wheels 18 are located on the inner side of the conveyor belt 15, and the drive shaft 13 is located on the outer side of the conveyor belt 15. In an optional embodiment, the axial distance between the two second idler wheels 18 is smaller than the diameter of the drive shaft 13, so that under the action of the second idler wheels 18, the wrapping angle of the conveyor belt 15 on the drive shaft 13 is increased, thereby increasing the contact area.
[0054] The embodiment of the utility model is applied to a conveying device with a long conveying path. The conveying device needs to be spliced by multiple sections of conveying tracks 10. The conveyed objects include small objects such as small tubes, which are easy to get stuck in the splicing gaps between the conveying tracks 10.

The conveying device proposed in this embodiment includes at least two sections of conveying tracks 10, and the conveying tracks 10 are spliced in sequence along the conveying direction; each section of the conveying track 10 includes an input end 10a and an output end 10b, and the height of the output end 10b in the horizontal direction is higher than the height of the input end 10a, so that the input end 10a of each section of the conveying track 10 is located below the output end 10b of the adjacent conveying track 10. There is no horizontal gap between the conveying rails 10, and the connection positions between the conveying rails 10 are the output end 10b and the input end 10a which are displaced in height. The blood bag 30 falls from the output end 10b of the previous conveying rail 10 to the input end 10a of the next conveying rail 10, and then continues to be conveyed on the next conveying rail 10 without being stuck at the splicing position of the conveying rail 10, thereby ensuring smooth conveying of the conveying device.
