Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical instrument production, and particularly relates to a virus sampling tube controllable feeding mechanism and a process thereof. BACKGROUND

[0002] The virus sampling tube is a centrifugal tube for microbial sampling and transportation. The overall outer contour of the virus sampling tube is close to a cylinder, and the shape is not very complex. The virus sampling tube is a product of large-scale production, and needs to be continuously circulated on an automatic production line.

[0003] In the existing mass production, the virus sampling tubes are pushed one by one, and the adjacent virus sampling tubes are in contact with each other, which is equivalent to continuous feeding. In order to facilitate specific processing requirements or to control the feeding quantity per unit time, a shut-off mechanism is generally required. The most common shut-off mechanism is to use a releasable insertion rod, which is inserted into the gap between the two sampling tubes at a moment, and all the upstream sampling tubes are limited, and the downstream sampling tubes continue to feed, but this shut-off method is relatively extensive. SUMMARY

[0004] Therefore, the subject group of the present application collects relevant data, evaluates and considers various aspects, and finally leads to the emergence of the quick assembly type light load bridge through continuous experiments and modifications of the subject group.

[0005] In order to solve the above technical problems, the present application relates to a virus sampling tube controllable feeding mechanism, which comprises: a vertical channel, a pair of parallel side plates form a vertical channel for the sampling tubes to pass through one by one; a valve block arranged on both sides of the vertical channel, the side plate has a hollow hole for exposing the valve block, the valve block itself penetrates a rotating shaft, and the valve block has a rotating freedom degree synchronous with the axis of the rotating shaft; a cylindrical block, the opposite surface of the valve block is provided with a concave curved groove, the cylindrical block is clamped in the concave curved groove, the circumferential surface of the cylindrical block is convex to the opening of the concave curved groove, the cylindrical block has a self-rotation freedom degree in the concave curved groove, the cylindrical block penetrates the hollow hole, and the two cylindrical blocks jointly hold one sampling tube; the axes of the rotating shaft, the sampling tube and the cylindrical block are horizontal and parallel; the valve blocks on both sides of the vertical channel are synchronously rotated and real-time mirror-symmetrical.

[0006] The beneficial effects of the above technical solution are: the mechanism can realize the feeding of the sampling tubes one by one, and change the feeding mode of the sampling tubes pushed one by one into a precise feeding mode. Thus, the output quantity of the sampling tubes per unit time is controlled, and the secondary precise operation on the sampling tubes is facilitated.

[0007] The main features are as follows: 1. The valve block using mirror image movement is used to control the release and clamping of the sampling tube. With the swing, some parts of the valve block are close to each other, and some parts are away from each other. These local positions are also dynamically switched, so the position away from each other can release the sampling tube, and the position close to each other is the clamping position of the sampling tube.

[0008] 2. The concave curved groove limits the position of the cylindrical block, but does not limit the self-rotation freedom of the cylindrical block. The self-rotating cylindrical block can follow the rotation when the sampling tube passes through, reducing the resistance and friction when the sampling tube passes through, ensuring smooth feeding each time, and reducing the wear of the sampling tube.

[0009] 3. The vertical channel guides the sampling tube, and the sampling tube is arranged in a row, which is convenient for subsequent feeding one by one.

[0010] 4. Due to the shape of the valve block, the sampling tube held by the cylindrical block can be released, but the second last sampling tube can be clamped and limited by the top of the valve block, and then all the sampling tubes above it are limited.

[0011] As a further improvement of the disclosed technical solution of the application, the opening width of the concave curved groove is smaller than the outer diameter of the cylindrical block.

[0012] The beneficial effects of the above technical solution are that the cylindrical block itself will not fall off.

[0013] As a further improvement of the disclosed technical solution of the application, the concave curved groove is located in the middle of the facing surfaces of the two valve blocks; when the facing surfaces of the two valve blocks on both sides of the vertical channel are parallel to each other, the distance between the cylindrical blocks on both sides of the vertical channel is smaller than the outer diameter of the sampling tube; the distance between the axes of the cylindrical blocks on both sides of the vertical channel is smaller than the distance between the axes of the shafts on both sides of the vertical channel, and the axis of the shaft is lower than the height of the axis of the cylindrical block.

[0014] The beneficial effects of the above technical solution are that the positions of the cylindrical block and the shaft are considered, so that the valve block can be close to or away from each other during the swing. The cylindrical blocks on both sides realize line contact with the sampling tube.

[0015] As a further improvement of the disclosed technical solution of the application, the inner wall of the concave curved groove is coated with lubricating oil, the bottom of the valve block is provided with a countersunk hole communicating with the concave curved groove, a bolt is arranged in the countersunk hole, and the end of the bolt is in contact with the outer wall of the cylindrical block.

[0016] The beneficial effect of the above technical scheme is that the lubricating oil can reduce the resistance of the cylindrical block when it rotates by itself. The countersunk hole and the bolt are a kind of rich design, which is convenient for later debugging. When the resistance of the cylindrical block when it rotates by itself is too small in some cases, it may cause the sampling tube to fall too smoothly. When more than one sampling tube falls at the same time, the bolt in the countersunk hole is used to press the cylindrical block, thereby increasing the resistance of the cylindrical block when it rotates by itself.

[0017] As a further improvement of the disclosed technical scheme, the top of a side plate is provided with an upwardly extending upper pressing plate, the vertical downward projection of which intersects with both side plates; the outer wall of the sampling tube is in contact with the lower surface of the upper pressing plate.

[0018] The beneficial effect of the above technical scheme is that the upper pressing plate is used to guide the horizontally conveyed sampling tube to be conveniently vertically conveyed into the vertical channel.

[0019] As a further improvement of the disclosed technical scheme, a downwardly extending discharging inclined plate is arranged below the vertical channel, the outer wall of the sampling tube is in contact with the upper surface of the discharging inclined plate, and the upper pressing plate and the discharging inclined plate extend to the same side of the vertical channel.

[0020] The beneficial effect of the above technical scheme is that the discharging inclined plate is used to guide the finally falling sampling tubes to flow onto another lower assembly line one by one.

[0021] As a further improvement of the disclosed technical scheme, the two ends of the two shafts are connected through the oppositely extending connecting rods, the two connecting rods at the same end are connected through the pin shaft; the one shaft is vertically fixed with a downwardly extending swing rod, the bottom end of the swing rod is fixed with a linear cylinder, and the linear cylinder is horizontally telescopic and drives the swing rod to periodically swing.

[0022] The beneficial effect of the above technical scheme is that the connecting rods connected through the pin shaft can ensure that the two shafts mirror rotate. The linear motion of the linear cylinder can be converted into the rotation of the swing rod with the top end thereof as the center.

[0023] As a further improvement of the disclosed technical scheme, the shafts are penetrated by end plates, each end plate is provided with two circular holes for the shafts to penetrate; the lower surface of the linear cylinder is fixed with a bottom plate, and the relative positions of the end plates and the bottom plate are fixed.

[0024] The beneficial effect of the above technical scheme is that the circular holes of the end plates are convenient for erecting the shafts, and the bottom plate and the end plates can be understood as part of the rack.

[0025] As a further improvement of the disclosed technical scheme, bearings are sleeved on the shafts, one side of the bearings is in contact with the end plates; C-shaped clamps are also sleeved on the shafts, the top end of the swing rod is fixed with the C-shaped clamps through a plurality of screws; the number of valve blocks is four.

[0026] The beneficial effect of the above technical scheme is that the C-shaped clamp expands the radial dimension and increases the fixing points, so that the fixed parts on the rotating shaft are synchronous rotation and will not be loose, especially for transmitting the rotation angle of the swing rod.

[0027] As a further improvement of the disclosed technical scheme, a process includes the controllable sampling tube supply mechanism as mentioned above, and the process steps are as follows: step one, a single column of sampling tubes is inserted into the vertical channel, and the adjacent sampling tubes in the vertical channel are in contact with each other; step two, the valve block makes a swing motion with the respective bottoms close to each other until the spacing between the two cylindrical blocks is not less than the outer diameter of the sampling tube; step three, after a sampling tube falls off between the cylindrical blocks, the valve block swings in the opposite direction until the two valve blocks are parallel to each other, and then returns to step two and circulates.

[0028] The beneficial effect of the above technical scheme is that the process matched with the mechanism, the self-rotation angle of the valve block is not large, and the sampling tube can be controlled to fall one by one at a speed within such a not large self-rotation angle.
