Description

Technical Field

[0001] This utility model relates to the field of medical device manufacturing technology, and more specifically, it relates to a sampling tube delivery device. Background Technology

[0002] In the production of medical devices, the transport and handling of sampling tubes is an important daily task. However, existing transport equipment often has the problem of unstable clamping, which can easily cause the sampling tubes to shake or fall off, affecting work efficiency and potentially leading to safety hazards such as sample leakage.

[0003] Furthermore, in practical applications, there may be height differences between different workstations. Traditional fixed-angle conveying devices cannot adapt to this situation and require additional auxiliary equipment for transfer, which increases the number of operation steps, reduces work efficiency, and also increases the risk of sample contamination and damage.

[0005] In view of the problems existing in the prior art, this utility model provides a sampling tube conveying device to solve the technical problem mentioned in the background art that existing conveying equipment often has unstable clamping.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sampling tube conveying device, comprising a base frame, on which a conveying mechanism is mounted, the conveying mechanism comprising an adjusting mechanism, support plates, conveying rollers, a conveyor belt, a motor, a driving wheel, and a driven wheel. The adjusting mechanism is mounted on the base frame. Two sets of support plates are provided, and two sets of conveying rollers are rotatably mounted between the two sets of support plates. The conveyor belt is located outside the conveying rollers, the motor is mounted outside the support plates, and the driving wheel is mounted at the motor output end. The driven wheel is installed at one end of the conveyor roller and meshes with the driving wheel. The conveyor belt is provided with multiple sets of clamping mechanisms. Each clamping mechanism includes a clamping sleeve, an inclined slide groove, an inclined slider, an arc plate, a compression spring, a clamping plate, and a pushing mechanism. The clamping sleeve is installed on the outside of the conveyor belt. Multiple sets of inclined sliders are provided on the inner wall of the clamping sleeve. The inclined sliders slide in multiple sets of inclined slide grooves. The arc plate is installed on the inner side of multiple sets of inclined sliders. Multiple sets of compression springs are provided on the inner side of multiple sets of arc plates. The clamping plate is installed on the top of multiple sets of compression springs.

[0008] The present invention is further configured such that the adjusting mechanism includes a support frame, a hinge rod, a support shaft, a push shaft, a connecting block, a hinge block, a screw, and a throttle. The support frame is mounted on a base frame. Multiple sets of hinge rods are provided, with both ends rotatably connected to the support plate and the support frame. The support shaft and the push shaft are rotatably mounted between the multiple sets of hinge rods. The connecting block is rotatably mounted on the push shaft. The hinge block is mounted on the support frame. The screw is threadedly connected to the hinge block and the connecting block. The throttle is mounted on the bottom end of the screw.

[0009] The present invention is further configured such that the pushing mechanism includes a sliding sleeve, a sliding rod, a sliding sleeve, a push plate, a guide rod, and a connecting spring. The sliding sleeve is slidably mounted on the outer wall of the clamping sleeve. Multiple sets of sliding rods are provided and mounted on the inner wall of the sliding sleeve. The sliding sleeve is slidably mounted on the outer wall of multiple sets of sliding rods. The push plate is mounted on the bottom end of multiple sets of sliding sleeves.

[0039] In this embodiment, the motor 31 drives the drive wheel 32 to rotate, which in turn drives the conveyor roller 29 to rotate through meshing with the driven wheel 33, thereby driving the conveyor belt 30 to run. The support plate 28 provides stable support for the entire conveying system, ensuring that the conveyor belt 30 runs smoothly. By rotating the throttle 15, the screw 14 is driven to rotate between the hinge block 13 and the connecting block 12, pushing the connecting block 12 to move. The connecting block 12 drives the push shaft 11 to move. Through the linkage of multiple sets of hinge rods 9, the angle of the support plate 28 can be adjusted. The support shaft 10 ensures the stability of the adjustment process. The sampling tube is placed in the clamping sleeve 2. The sliding block 4 is controlled by the push mechanism to slide in the inclined slide groove 3, driving the arc plate 5 to move. The compression spring 6 is compressed to generate clamping force. The sampling tube is fixed by the clamping plate 7. The soft pad 22 protects the sampling tube from damage.

[0040] More specifically, when the inclined slider 4 needs to be manipulated, the sliding sleeve 16 is pulled by multiple sets of first tension springs 23 and second tension springs 24 to slide on the outer wall of the clamping sleeve 2, which drives the slide rod 17 to move. The sliding sleeve 18 slides on the slide rod 17, and the sliding sleeve 18 adjusts the push plate 19 to abut against the bottom surface of the inclined slider 4. The push plate 19, through the cooperation of the guide rod 20 and the inclined surface, pushes the inclined slider 4 and simultaneously squeezes the push spring 27. When it is necessary to release, the sliding sleeve 16 is pulled downward by the pull rod 25, and the multiple sets of first tension springs 23 and second tension springs 24 are pulled up. The sliding sleeve 16 drives the push plate 19 to release the contact with the inclined slider 4 through the slide rod 17 and the sliding sleeve 18. The multiple sets of push springs 27 push the inclined slider 4 to unfold outward along the inclined slide groove 3, thereby driving the multiple sets of clamping plates 7 to release the clamping of the sampling tube.

[0041] In summary, during the use or operation of the overall equipment: the motor 31 drives the drive wheel 32 to rotate, which in turn drives the conveyor roller 29 to rotate through meshing with the driven wheel 33, thereby driving the conveyor belt 30 to run. The support plate 28 provides stable support for the entire conveying system, ensuring the smooth operation of the conveyor belt 30. By rotating the throttle 15, the screw 14 is driven to rotate between the hinge block 13 and the connecting block 12, pushing the connecting block 12 to move. The connecting block 12 drives the push shaft 11 to move. Through the linkage of multiple sets of hinge rods 9, the angle of the support plate 28 can be adjusted. The support shaft 10 ensures the stability of the adjustment process. The sampling tube is placed in the clamping sleeve 2. The sliding block 4 is controlled by the push mechanism to slide in the inclined slide groove 3, driving the arc plate 5 to move. The compression spring 6 is compressed to generate clamping force. The sampling tube is fixed by the clamping plate 7. The soft pad 22 protects the sampling tube from damage.

[0042] When the inclined slider 4 needs to be operated, the sliding sleeve 16 is pulled by multiple sets of first tension springs 23 and second tension springs 24 to slide on the outer wall of the clamping sleeve 2, which drives the slide rod 17 to move. The sliding sleeve 18 slides on the slide rod 17. The sliding sleeve 18 adjusts the push plate 19 to abut against the bottom surface of the inclined slider 4. The push plate 19 pushes the inclined slider 4 and squeezes the push spring 27 at the same time through the cooperation of the guide rod 20 and the inclined surface. When it is necessary to release, the sliding sleeve 16 is pulled downward by the pull rod 25 and the multiple sets of first tension springs 23 and second tension springs 24 are pulled up. The sliding sleeve 16 drives the push plate 19 to release the abutment against the inclined slider 4 through the slide rod 17 and the sliding sleeve 18. The multiple sets of push springs 27 push the inclined slider 4 to unfold outward along the inclined slide groove 3, thereby driving the multiple sets of clamping plates 7 to release the clamping of the sampling tube.
