Description

Technical Field

[0001] This utility model relates to the field of biological sample processing equipment technology, specifically to a calf fibrin shaker device. Background Technology

[0002] In the production and processing of calf serum and related biological products, defibrinogen removal is a crucial pretreatment step. If the fibrinogen in freshly collected calf blood is not removed in a timely and sufficient manner, it is very easy to coagulate, which directly affects the extraction yield of subsequent effective components and the purity of the product. The efficiency and effect of defibrinogen removal by shaking are directly related to the capacity and quality of the entire production line. Early defibrinization processes mostly relied on manual hand-held blood storage containers to be shaken repeatedly. This was not only labor-intensive and limited in the amount that could be processed per batch, but also resulted in significant differences in the shaking force, frequency, and amplitude among different operators. Consequently, the defibrinization effect varied from batch to batch, making it difficult to meet the standardization requirements of large-scale production. With the increasing automation of production, various mechanical shaking tables are gradually replacing manual labor. The motor drives the carrier platform to make regular movements, which causes the blood in the container to shake synchronously to complete the removal of fibers. This reduces labor costs to a certain extent and improves the stability of the operation. Currently, one of the most widely used types of shaking equipment uses a slide rail and a transmission mechanism to drive the platform to make a linear reciprocating motion. The structure is relatively simple and the operation is relatively stable. However, this single linear shaking method results in a relatively simple flow pattern of blood inside the container, limited shear force and turbulence effects inside the liquid, and a slow fibrin release rate. The overall processing efficiency improvement is limited and it is difficult to meet the production needs of high capacity. Some shakers use a rack and pinion transmission structure to drive the carrying platform to swing in an arc around a fixed axis. Compared with linear reciprocating equipment, this increases the shaking amplitude of the container. They are also equipped with an adjustable lateral clamping structure to accommodate containers of different sizes. However, these devices are essentially still single-dimensional oscillating motions. The movement trajectory of blood in the container is relatively fixed, which cannot fully break up the flow stratification of the liquid. Therefore, the effect on improving the efficiency of fibrin removal is not significant. Moreover, this type of clamping structure can only rigidly limit the container from the side and can only restrict the horizontal displacement of the container. If a multi-dimensional compound shaking condition is used, the container is very likely to move up and down or even slip off the platform, which poses certain operational safety hazards. Therefore, it is impossible to further improve the processing efficiency by increasing the dimension of motion. Utility Model Content

At the same time, through the fixing components that combine lateral elastic clamping and L-shaped pressure plate pressing up and down, the fixing stability of the container and the safety of equipment operation under multi-dimensional shaking conditions are improved, ensuring the efficient and stable operation of calf blood defibrinating.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: like Figure 1 , 2 As shown in Figure 3, a calf blood fibrin shaker device includes a base 1. A circular slide rail 2 is provided on the upper part of the base 1. Two sliders 3 are symmetrically slidably connected on the circular slide rail 2. Support rods 4 are fixedly connected to the corresponding sliders 3. A rotating plate 5 is fixedly supported on the upper end of the two support rods 4.

The cylinders of the telescopic rods 12 are respectively fixedly connected to the rotating plate 5. Multiple fixing components for fixing the calf blood container are provided on the upper part of the swing plate 11.

[0016] like Figure 1 , 2As shown in Figure 3, the fixing assembly includes a positioning plate 14 fixedly connected to the swing plate 11. A sliding plate 15 is provided on the symmetrical side of the positioning plate 14. A sliding block 16 is fixedly connected to the lower part of the sliding plate 15. The sliding block 16 is slidably connected to the sliding groove 17 opened on the swing plate 11. A tension spring 18 is provided between the sliding block 16 and the sliding groove 17. Several rubber bands 19 for wrapping around the calf blood container are respectively connected between the left and right sides of the sliding plate 15 and the positioning plate 14.

[0017] like Figure 1 , 2 As shown in Figure 3, the sliding plate 15 and the positioning plate 14 are respectively provided with cavities 20. An L-shaped pressure plate 21 is slidably connected in the cavity 20. The horizontal section of the L-shaped pressure plate 21 extends toward the center of the fixing component and is used to press the small blood container from above. A spring is connected between the cavity 20 and the corresponding L-shaped pressure plate 21.

[0018] like Figure 1 , 3 As shown, the drive motor 9 is fixed to the upper part of the base 1 via a bracket.

[0019] like Figure 1 , 2 As shown, one end of the tension spring 18 is connected and fixed to the sliding block 16, and the other end is connected and fixed to the side wall of the slide groove 17 near the positioning plate 14.

[0020] like Figure 1 , 3 As shown, the telescopic rod 12 adopts any one of electric push rod, pneumatic cylinder or hydraulic cylinder. The two telescopic rods 12 also include an automatic control system. The automatic control system includes a PLC controller 13. The PLC controller 13 is electrically connected to the drive motor 9 and the telescopic rod 12 respectively, and is used to control the forward and reverse rotation cycle of the drive motor 9 and the extension and retraction frequency of the telescopic rod 12.

[0021] like Figure 1 , 3 As shown, the back of the sliding plate 15 is provided with a handle 22 to facilitate its movement.

[0022] like Figure 1 , 3 As shown, the rotating shaft 6 is rotatably connected to the base 1 through a bearing seat, and the bearing seat is fixedly installed on the upper middle part of the base 1.

[0023] like Figure 1 , 3 As shown, the piston rod end of the telescopic rod 12 is hinged to the lower part of the swing plate 11, and the cylinder end of the telescopic rod 12 is fixedly connected to the upper surface of the rotating plate 5.

[0024] The implementation principle of the calf fibrin shaker device in this application is as follows: In use, first place the containers of calf blood one by one into the fixing components on the upper part of the swing plate 11. Before placing, pull the handle 22 on the back of the sliding plate 15 to make the sliding block 16 slide outward along the slide groove 17 and stretch the tension spring 18. After the container is placed between the positioning plate 14 and the sliding plate 15, release the handle 22. The tension spring 18 rebounds and drives the sliding plate 15 to return to its original position. With the help of the surrounding rubber band 19, the container is elastically clamped from the side. Then, pull the L-shaped pressure plate 21 upward. The spring in the cavity 20 will generate a rebound force. When the horizontal section of the L-shaped pressure plate 21 is close to the upper edge of the container, the L-shaped pressure plate 21 will be pressed down from the top and fixed under the action of the spring rebound force. Through the dual constraints of lateral clamping and upper and lower pressing, it is ensured that the container will not move or slip during multi-dimensional shaking, which is suitable for the fixing requirements of complex shaking conditions. After the container is fixed, the forward and reverse rotation cycle of the drive motor 9 and the extension and retraction frequency of the telescopic rod 12 are set by the PLC controller 13. After the equipment is started, the drive motor 9 drives the drive wheel 8 to rotate, and through gear meshing, it drives the driven wheel 7 to rotate synchronously with the rotating shaft 6, thereby driving the rotating plate 5 to rotate around the axis of the rotating shaft 6 in a circumferential motion. The circular slide rail 2 on the upper part of the base 1 works in conjunction with the slider 3 and the support rod 4 to provide uniform and stable rotational support for the rotating plate 5, ensuring smooth and stable rotation. The rotating shaft 6 is rotatably connected to the base 1 through the bearing seat, which can effectively withstand radial and axial loads and improve the structural reliability of the equipment operation. At the same time, the telescopic rods 12 on the left and right sides of the swing plate 11 extend and retract alternately, pushing the swing plate 11 to reciprocate pitching and swaying around the hinge axis between the two connecting plates 10. While the container rotates around the rotating plate 5, it also reciprocates and sways with the swing plate 11, forming a two-dimensional compound shaking effect of rotation and swaying. This causes complex turbulence and continuous shearing action in the calf blood inside the container, which fully breaks the liquid flow stratification, greatly accelerates the fibrin precipitation rate, and significantly improves the processing efficiency of fibrin removal. During operation, the rotation speed, swing amplitude and operating frequency can be flexibly adjusted by the PLC controller 13 according to the processing requirements of different batches of calf blood, so as to adapt to diverse production and processing needs. The entire operation process utilizes a multi-dimensional shaking structure that combines rotation and oscillation, fundamentally solving the problems of insufficient liquid turbulence and low fibrin removal efficiency in traditional single-dimensional shakers. Combined with a fixing assembly that integrates lateral elastic clamping and L-shaped pressure plates 21 for vertical clamping, it completely eliminates the safety hazard of container slippage under multi-dimensional shaking. This significantly improves processing efficiency while ensuring equipment operational stability, fully meeting the large-scale and standardized production and processing needs of the biopharmaceutical industry.
