[0023] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0024] According to an embodiment of the present invention, a rolling and flipping mechanism is provided. Figures 1 to 4 , including: a rolling assembly 20, the rolling assembly 20 includes a roller for supporting materials, the roller is rotatably arranged to drive the material to rotate; a flipping assembly 30, the flipping assembly 30 includes a flipping shaft 31 arranged at a distance from the roller, the flipping shaft 31 is connected to the roller, and the flipping shaft 31 is rotatably arranged to drive the roller to flip around the flipping shaft 31, so that the material on the roller falls.

[0025] By setting up the rolling component 20, the material can be driven to rotate on the roller, and the flipping component 30 can be used to drive the roller to flip around the flip axis 31, so that the material on the roller falls off the roller, completing the sorting or unloading of the material. The rolling and flipping mechanism in this embodiment can realize the material rotation function and unloading and sorting function with one mechanism, without the need to set up an additional unloading mechanism, simplifying the equipment structure, saving the equipment installation space, and solving the technical problems of complex structure and large space occupation of the sorting equipment in the related technology.

[0026] When the rolling and flipping mechanism in this embodiment is applied to the sorting equipment of sample tubes, the rolling component 20 can drive the material to rotate, so that the sorting equipment can identify and classify the material. After the identification is completed, the material can be discharged according to the type of material identified. By setting the sorting bin below the rolling component 20, the flipping component 30 drives the roller to flip around the flipping axis 31, so that the material falls directly into the sorting bin, completing the transfer or discharge of the material, thereby simplifying the structure of the sorting equipment, reducing the space occupied by the equipment, making the equipment structure integrated, and the installation modular.

[0027] In the rolling and flipping mechanism of this embodiment, see Figure 2 The flip assembly 30 includes a push rod 32 fixedly connected to the flip shaft 31; and a flip driving component 33. The output end 34 of the flip driving component 33 is retractably arranged so as to abut against the push rod 32 to drive the push rod 32 and the flip shaft 31 to rotate. With this arrangement, the flip driving component 33 is extended to abut against the output end 34 of the push rod 32, thereby automatically pushing the push rod 32, causing the push rod 32 to rotate, thereby driving the flip shaft 31 to rotate, thereby achieving automatic control.

[0028] In the rolling and flipping mechanism of this embodiment, see Figure 1The flip assembly 30 includes a connecting member 35 that extends through the flip shaft 31. The roller passes through the connecting member 35 and is movably connected to the connecting member 35. The connecting member 35 includes at least two connecting members 35, which are spaced apart along the extension direction of the roller. This arrangement connects the flip shaft 31 and the roller as a single unit. As the flip shaft 31 rotates, the connecting member 35 drives the roller to flip along with it. The roller is fixed only by the connecting member 35, and the driven rolling gear mounted on the roller can also flip along with the roller.

[0029] Specifically, the roller is movably connected to the connecting component 35 , that is, the roller is rotatably connected to the connecting component 35 , so that the roller can rotate, thereby completing the rotation function of the roller.

[0030] It is understandable that a bearing may be installed in the mounting hole of the connecting component 35 and the roller may be fixed by the bearing so that the roller can rotate.

[0031] In some embodiments, there are two connecting components 35 , which are respectively located at two ends of the roller.

[0032] In the rolling and flipping mechanism of this embodiment, see Figure 1 The rolling assembly 20 includes a first roller group 21 and a second roller group 22 arranged opposite to each other, each of the first roller group 21 and the second roller group 22 includes at least one roller, the flip shaft 31 includes a first flip shaft 311 connected to the first roller group 21 and a second flip shaft 312 connected to the second roller group 22; the flip assembly 30 includes a first driving gear 361 and a second driving gear 362 that are meshed with each other, the first driving gear 361 is fixedly sleeved on the first flip shaft 311, and the second driving gear 362 is fixedly sleeved on the second flip shaft 312.

[0033] By setting the first driving gear 361 and the second driving gear 362 that mesh with each other, torque can be transmitted to multiple driving gears, that is, when the first driving gear 361 obtains torque, it can drive the second driving gear 362 to rotate together, thereby driving the first roller group 21 and the second roller group 22 to complete the flipping at the same time. The first roller group 21 and the second roller group 22 are arranged relative to each other, and the material can fall from the middle of the first roller group 21 and the second roller group 22, thereby improving the falling efficiency of the material.

[0034] It can be understood that each roller group can include multiple rollers arranged in parallel, and the multiple rollers can be rotated simultaneously through the linkage of the driving structure. The design of multiple rollers can increase the bearing area of ​​the rolling assembly 20 and increase the amount of material that can be carried.

[0035] In the rolling and flipping mechanism of this embodiment, see Figure 1The push rod 32 is fixedly mounted on the first drive gear 361, so that the push rod 32 drives the first drive gear 361 and the first flip shaft 311 to rotate, and the first drive gear 361 drives the second drive gear 362 and the second flip shaft 312 to rotate. With the above arrangement, the first drive gear 361 obtains a rotational torque by rotating the push rod 32, and then the first drive gear 361 drives the second drive gear 362 to rotate together.

[0036] In the rolling and flipping mechanism of this embodiment, see Figure 2 The flip assembly 30 includes a return spring 37, the extension direction of which is aligned with the extension and retraction direction of the output end 34 of the drive component; and a return lever 38, one end of which is fixedly mounted on the second drive gear 362 and the other end of which is connected to the return spring 37. The return spring 37 and return lever 38 enable the second drive gear 362 and the first drive gear 361 to be quickly reset, returning the rolling assembly 20 to its initial state.

[0037] Specifically, when the second drive gear 362 rotates, it drives the reset rod 38 to rotate together, thereby stretching the reset spring 37. When the push rod 32 no longer abuts against the output end 34 of the flip drive component 33, the reset rod 38 is pulled by the reset spring 37 to rotate the reset rod 38, thereby driving the second drive gear 362 to rotate, so that the second drive gear 362, the first drive gear 361 and the rolling assembly 20 return to their initial state.

[0038] Specifically, the output end 34 of the driving component is provided with a roller to reduce friction during pushing.

[0039] In the rolling and flipping mechanism of this embodiment, see Figure 3 The rolling assembly 20 includes a rolling drive component 23; a driving rolling gear 24, which is drivingly connected to the rolling drive component 23; and a driven rolling gear 25, which is sleeved on the rolling shaft and meshes with the driving rolling gear 24. The driven rolling gear 25 and the driving rolling gear 24 drive the rolling shaft to rotate.

[0040] Specifically, the rolling drive component 23 includes a motor, a synchronous belt and a synchronous belt pulley, which transmits the torque transmitted by the motor to the active rolling gear 24 through the synchronous belt and the synchronous belt pulley. By setting the synchronous belt and the synchronous belt pulley, the motor can be set at a position away from the active rolling gear 24 and the roller, thereby avoiding key structures such as the driving structure of the flipping component.

[0041] In the rolling and flipping mechanism of this embodiment, see Figure 3The first roller assembly 21 includes a first roller 211, and the second roller assembly 22 includes a second roller 221. The driven rolling gear 25 includes a first driven rolling gear 251 and a second driven rolling gear 252. The first driven rolling gear 251 is fixedly mounted on the first roller 211, and the second driven rolling gear 252 is fixedly mounted on the second roller 221. The first driven rolling gear 251 and the second driven rolling gear 252 are spaced apart. With this arrangement, the driving rolling gear 24 simultaneously drives the first and second driven rolling gears 251, 252 to rotate, thereby causing the first and second rollers 211, 221 to simultaneously drive the material to rotate.

[0042] Preferably, each roller set comprises one roller.

[0043] Specifically, the first driven rolling gear 251 and the second driven rolling gear 252 are arranged at intervals, which can prevent the first driven rolling gear 251 and the second driven rolling gear 252 from getting stuck with each other during the flipping of the first roller 211 and the second roller 221, thereby ensuring that the flipping process can be completed smoothly.

[0044] It can be understood that during the flipping of the first roller 211 and the second roller 221, the first driven rolling gear 251 and the second driven rolling gear 252 are both away from the driving rolling gear 24. When the flipping is completed, the first driven rolling gear 251 and the second driven rolling gear 252 are reset to engage with the driving rolling gear 24.

[0045] It is understandable that the first roller 211 and the second roller 221 are turned downward, and the driving rolling gear 24 is disposed above the first driven rolling gear 251 and the second driven rolling gear 252 .

[0046] In the rolling and flipping mechanism of this embodiment, see Figure 2 The rolling and flipping mechanism includes a flip sensor 39. A flip sensing portion 321 is provided at the end of the push rod 32 away from the first driving gear 361. The flip sensing portion 321 is provided corresponding to the flip sensor 39. The flip sensor 39 is used to sense the position of the push rod 32. Among them, the flip sensor 39 includes multiple flip sensors 39, and the multiple flip sensors 39 are arranged at intervals along the rotation trajectory of the push rod 32.

[0047] Specifically, there are two flip sensors 39, which are respectively located at the initial position and the maximum stroke position of the push rod 32. When the push rod 32 reaches the maximum stroke position, the roller reaches the maximum flip stroke, the material on the roller meets the conditions for falling, and the push rod 32 and the flip shaft 31 can stop rotating.

[0048] By providing two flip sensors 39, the stroke and movement status of the push rod 32 can be monitored, thereby achieving further control and completing the automated sorting of the sorting equipment.

[0049] In the rolling and flipping mechanism of this embodiment, see Figure 4 The first drive gear 361 or the second drive gear 362 includes a first fixing hole 363 and a second fixing hole 364. The first fixing hole 363 is used to fix the push rod 32, and the second fixing hole 364 is used to fix the reset rod 38. The first fixing hole 363 and the second fixing hole 364 are symmetrically arranged on the first drive gear 361 or the second drive gear 362. This arrangement ensures the symmetry between the first fixing hole 363 and the second fixing hole 364, thereby achieving universality and interchangeability between the first drive gear 361 and the second drive gear 362, and improving assembly and installation efficiency.

[0050] Specifically, the first fixing hole 363 and the second fixing hole 364 each include two holes to prevent the push rod 32 and the reset rod 38 from rotating relative to each other.

[0051] The working process of the rolling and flipping mechanism in this embodiment is as follows:

[0052] The output end 34 of the flip driving component 33 extends out to push the push rod 32, causing the push rod 32 to rotate. The rotation of the push rod 32 drives the first driving gear 361 to rotate, thereby driving the second driving gear 362 to rotate together. The first flip shaft 311 and the second flip shaft 312 rotate at the same time, driving the first roller 211 and the second roller 221 to flip together, thereby causing the materials on the first roller 211 and the second roller 221 to fall into the sorting bin. When the output end 34 of the flip driving component 33 stops pushing the push rod 32, the reset rod 38 is pulled by the reset spring 37 to rotate the reset rod 38, thereby driving the second driving gear 362 to rotate, causing the second driving gear 362, the first driving gear 361 and the rolling assembly 20 to return to the initial state.
