[0045] Embodiment 1:

[0046] See also Figure 1-7 The present invention provides a blood bag tube sealing machine with a pulp separation function, comprising a frame 1, and also comprising

[0047] The pulp separation clamp structure 2 comprises a base 21, a squeezing plate 1 22, a squeezing plate 23 and a driving mechanism 24. The base 21 is mounted on one side of the frame 1.

[0049] Sealing machine structure 3; including an upper template 31, a lower template 32 and an adjusting frame 33, wherein the lower template 32 is fixedly mounted on the top of the frame 1, the adjusting frame 33 is arranged above the upper template 31, the upper template 31 is movably mounted on the adjusting frame 33, and a regulating mechanism 34 is arranged on the adjusting frame 33, and the regulating mechanism 34 is used to control the upper template 31 to move on the adjusting frame 33, and heat sealing heads are embedded in the opposite sides of the upper template 31 and the lower template 32, and the heat sealing heads are electrically connected to the high-frequency transmitter, and the high-frequency transmitter is controlled by the controller, and a pressure sensor is also arranged on the upper template 31, and the pressure sensor is installed at the pressure application part of the upper template 31 and the lower template 32, and the pressure sensor is connected to the controller, and the controller is installed on the other side of the frame 1, and a photoelectric element is also arranged on the upper template 31, and the photoelectric element is arranged close to the pressure sensor;

[0050] The pressure sensor is installed at the pressure application part of the upper template 31 and the lower template 32. The pressure sensor is connected to the controller. The controller controls the regulating mechanism 34 to adjust the pressure of the upper template 31. The controller is installed on one side of the frame 1.

[0051] The cutting mechanism 4 comprises a cutting knife 41 and a cylinder 42, wherein the cylinder 42 is installed at the center of the adjusting frame 33, the telescopic end of the cylinder 42 is connected to the cutting knife 41, the cutting knife 41 is arranged above the upper template 31, and a knife groove 35 for the cutting knife 41 to pass through is provided in the center of the upper template 31, the opposite surfaces of the upper template 31 and the lower template 32 are symmetrically provided with mounting grooves, the heat sealing head is installed in the mounting groove, the heat sealing head is annular, the pressure sensor is embedded in the center of the annular heat sealing head of the upper template 31, and the knife groove 35 is provided between the two heat sealing heads.

[0052] The driving mechanism 24 includes two one-way screws 241, a driving motor 242 and a pulley group 243. The two one-way screws 241 are symmetrically installed between the bearing seat 5 and the extrusion plate 23 at one end away from the frame 1, and are threadedly connected to the extrusion plate 1 22. Supports are installed on the extrusion plate 23 and the bearing seat 5. The two ends of the one-way screw 241 are respectively connected to the extrusion plate 23 and the bearings on the bearing seat 5. The pulley group 243 is connected to the outer wall of the bearing seat 5 and to the two bearings on the bearing seat 5. The driving motor 242 is connected to one of the sprockets in the pulley group 243.

[0053] When in use, the blood bag is placed on the receiving plate 25 between the squeezing plate 1 22 and the squeezing plate 2 23. The receiving plate 25 supports the blood bag to ensure the stability of the blood bag during the pulping process. The through holes on the blood bag are hung on the positioning pins 221 as needed. Before pulping, the pulping pipeline is placed on the lower template 32 so that the pipeline is located in the sealing area between the upper template 31 and the lower template 32. Then the driving motor 242 is turned on, and the power of the driving motor 242 is transmitted to the two one-way screws 241 through the pulley group 243. Since the pulley group 243 is connected to the two bearings on the bearing seat 5, the two one-way screws 241 rotate synchronously, and the one-way screw 241 and the squeezing plate 22 are connected. Threaded connection, when the one-way screw 241 rotates, the extrusion plate 1 22 moves along the axial direction of the screw toward the extrusion plate 2 23 under the action of the thread, thereby realizing the clamping operation of the blood bag, separating the blood in the blood bag, and squeezing the stratified serum through the hose to another empty blood bag. In this process, the operator can accurately adjust the extrusion force and the moving speed of the extrusion plate 1 22 according to the characteristics of the blood bag and the demand for slurry separation by controlling the speed and direction of the drive motor 242. When the photoelectric element detects the critical position of blood stratification, it triggers the host to control the heat sealing head to clamp the blood bag tube and simultaneously transmit a high-frequency signal to fuse the pipeline, thereby realizing intelligent separation and sealing of plasma. After completion, just pull the sealing groove tangent line with a little force to separate the connecting tube. The device can not only accurately control the timing and space of blood bag squeezing to ensure the separation of blood components, but also automatically complete the sealing and separation of blood bag tubes, improve the sealing quality of pipelines, and avoid pollution and waste of blood components. The regulating mechanism 34 is started. According to the material, specifications and other parameters of the pipeline, the controller controls the regulating mechanism 34 to adjust the position of the upper template 31 on the adjusting frame 33, so that the upper template 31 gradually approaches the lower template 32 until it contacts the pipeline. The heat sealing heads embedded in the opposite sides of the upper template 31 and the lower template 32 start to work to heat the pipeline. The pressure sensor monitors the application of the upper template 31 and the lower template 32 to the pipeline in real time. The pressure at the pressure part is adjusted, and the pressure data is transmitted to the controller. The controller adjusts the pressure applied by the upper template 31 in real time through the regulating mechanism 34 according to the preset pressure value to ensure that the pipeline completes the sealing operation at a suitable pressure and temperature. When the sealing is completed, the cylinder 42 is started. The cylinder 42 is installed in the center of the adjusting frame 33, and its telescopic end is connected to the cutting knife 41. The telescopic end of the cylinder 42 pushes the cutting knife 41 to move downward. The cutting knife 41 cuts the sealed pipeline through the knife groove 35 opened in the center of the upper template 31, so as to subsequently store and transport the blood products after slurry separation. In this embodiment, the device is driven by two one-way screws 241 and a pulley group 243.This design greatly reduces the number of parts and eliminates the complex considerations of differences in screw rotation directions, which not only reduces the difficulty of manufacturing and makes the production process simpler and more efficient, but also significantly shortens the production cycle and reduces production costs. For small blood stations or laboratories, this simple design can obtain reliable pulp separation equipment at a lower cost within a limited budget. During the pulp separation process, the unidirectional screw 241 can provide precise unidirectional extrusion force, and the operator can accurately control the movement trajectory and extrusion force of the extrusion plate 22 by controlling the drive motor 242.

[0054] In the existing sealing equipment, it is often difficult to accurately control the sealing pressure, resulting in uneven sealing quality. In this equipment, a pressure sensor is arranged on the upper template 31 of the sealing machine structure 3. The pressure sensor is installed at the pressure application part of the upper template 31 and the lower template 32 and is connected to the controller. The pressure sensor can monitor the sealing pressure in real time and transmit the pressure data to the controller. The controller accurately adjusts the pressure of the upper template 31 through the regulating mechanism 34 according to the preset pressure value. This closed-loop control method can ensure that the pipeline is always subjected to appropriate pressure during the sealing process, effectively improves the stability of the sealing quality, and reduces the problems of loose sealing and leakage caused by improper sealing pressure.

[0055] Since the sealing pressure can be accurately controlled, the device can flexibly adjust the sealing pressure through the controller according to the materials and specifications of different pipes. Compared with some sealing devices in the prior art that cannot adjust the pressure according to the characteristics of the pipe, the design can better adapt to the sealing needs of various pipes and improve the versatility of the equipment. In the existing equipment, the cutting and sealing functions are often separated, and the sealed pipe needs to be manually transferred to the cutting equipment for cutting, which is cumbersome and inefficient. The device integrates the cutting mechanism 4 into the sealing machine structure 3. When the sealing is completed, the cylinder 42 drives the cutting knife 41 to immediately cut the sealed pipe. This integrated design realizes the seamless connection between the cutting and sealing processes, greatly improves the work efficiency, reduces the manual operation links, and reduces the possibility of human errors. The cutting knife 41 is arranged above the upper template 31, and a knife groove 35 for the cutting knife 41 to pass through is opened in the center of the upper template 31, and the knife groove 35 is arranged between the two heat sealing heads. This design ensures that the cutting knife 41 can accurately cut the sealing part and avoids the influence of the cutting position deviation on the sealing quality of the pipe.

[0056] Embodiment 2:

[0057] See also Figure 2-7In the first embodiment, since the unidirectional screw 241 is designed in the pulp separation clamp structure 2, in order to improve the use efficiency of the pulp separation clamp, the following further improvement is proposed. Different from the first embodiment, the driving mechanism 24 also includes a bidirectional screw 244, and the bidirectional screw 244 is symmetrically rotatably installed between the two bearing seats 5. One end of the bidirectional screw 244 passes through the extrusion plate 1 22 and the extrusion plate 2 23 and is connected and fixed to the bearing seat 5 through a bearing.

[0058] When in use, the driving motor 242 is turned on, and the power of the driving motor 242 is transmitted to the two bidirectional screws 244 through the pulley group 243. Since the pulley group 243 is connected to the two bearings on the bearing seat 5, the two bidirectional screws 244 rotate synchronously. The bidirectional screws 244 are threadedly connected with the extrusion plate 1 22 and the extrusion plate 23. When the bidirectional screws 244 rotate, the extrusion plate 1 22 and the extrusion plate 23 move relative to each other under the action of the threads. At the same time, guide blocks are also provided at the bottom of the extrusion plates 1 22 and the extrusion plates 23. The guide blocks slide along the base 21, so that The squeezing plate 1 22 and the squeezing plate 2 23 move more stably, thereby realizing the clamping operation of the blood bag and performing slurry processing on the blood in the blood bag. In this embodiment, the bidirectional screw 244 can make the squeezing plate 1 22 and the squeezing plate 2 23 move toward the middle of the blood bag simultaneously and symmetrically, ensuring that the squeezing force on the top and bottom of the blood bag is uniform. The bidirectional screw 244 drives the two squeezing plates to move synchronously. Compared with the unidirectional screw 241 driving one squeezing plate to move, the squeezing process of the blood bag can be completed faster in the same time. When blood samples are processed in batches at blood stations, this high efficiency advantage is obvious.

[0059] Embodiment three:

[0060] Please refer to Figure 1-3 Both ends of the bidirectional screw 244 and the unidirectional screw 241 are sleeved with compression springs 245, and the ends of the compression springs 245 are connected with movable pins, and the movable pins are connected to the bearing seat 5 or the bearing on the extrusion plate 23.

[0061] When the pulp separator is working, the bidirectional screw 244 or the unidirectional screw 241 rotates at high speed to drive the extrusion plate 1 22 or the extrusion plate 2 23 to extrude the blood bag. Vibration and impact force will be generated in this process. The compression spring 245, with its good elasticity, acts like a shock absorber to effectively absorb and buffer these vibration and impact energy. Compared with the traditional method of directly connecting the screw to the bearing seat 5, the impact of vibration on the equipment structure is greatly reduced, which makes the equipment more stable during operation and avoids problems such as loosening and displacement of components caused by vibration, thereby ensuring the stable operation of the equipment. When pulping, the liquid in the blood bag is unevenly distributed, and the force on the bidirectional screw 244 or the unidirectional screw 241 changes. The compression spring 245 can automatically adjust the elastic force according to the force, stably support the bidirectional screw 244 or the unidirectional screw 241, and avoid damage to components due to uneven force.

[0062] Embodiment 4:

[0063] Please refer to Figure 4 , Figure 7 A pipe guide groove 11 is provided on the top of the frame 1, and the lower template 32 is arranged at the center of the pipe guide groove 11. The width of the pipe guide groove 11 is consistent with the width of the upper template 31 and the lower template 32. Pipe clamps 12 are connected at both ends of the pipe guide groove 11, and the clamping center of the pipe clamp 12 is consistent with the center line of the pipe guide groove 11.

[0064] A buffer block 13 is detachably provided on the top of the lower template 32, a positioning groove 15 is provided on the pipeline guide groove 11, and the buffer block 13 is buckled on the positioning groove 15. A buffer block 2 is detachably provided on the upper template 31, and a clamping groove is symmetrically provided at the bottom of the upper template 31, and the buffer block 2 14 is slidably clamped in the clamping groove.

[0065] Before operation, the detachable buffer block 13 is connected to the positioning groove 15 of the pipe guide groove 11 by snapping, and the buffer block 2 14 is installed in the slot at the bottom of the upper template 31. At this time, the slurry distribution tube is passed through the pipe clamp 12 and the pipe guide groove 11 in turn, and the pipe clamp 12 at one end is passed through and connected to the empty blood bag, and then the slurry distribution tube is pre-clamped by the pipe clamp 12, so that the slurry distribution tube is close to the center of the pipe guide groove 11, and there is a movable space between the pipe clamp 12 and the slurry distribution tube, which is convenient for following movement when using the two-way screw 244. The slurry distribution tube is placed between the buffer blocks of the upper template 31 and the lower template 32. The staff first accurately adjusts the distance between the upper template 31 and the lower template 32 through the regulating mechanism 34 according to the material and specifications of the pipeline. Subsequently, the high-precision pressure sensor begins to monitor the sealing pressure of the mold on the pipeline in real time, and transmits the pressure data to the control system. The control system automatically adjusts the pressure of the mold through the motor and the transmission device according to the preset pressure value. At the same time, the new ceramic inside the upper and lower molds The heating plate starts to work to heat and seal the slurry distribution pipe. During the heating and sealing process, due to the softening of the pipe due to heat, some molten materials or other contaminants may be generated. When these contaminants drip under the action of gravity, they will be blocked by the detachable buffer block to prevent them from dripping on the machine body, thereby keeping the machine body clean and reducing the workload of equipment maintenance. When the sealing is completed, the buffer block can also assist the upper template 31 and the lower template 32 to separate from the sealed pipe, making the operation smoother, reducing the adhesion between the pipe and the template, and improving work efficiency. After a batch of pipe sealing operations are completed, the staff can easily remove the detachable buffer block from the mold, clean or replace it for next use. At the same time, the buffer block 14 set on the upper template 31 can also be used to scrape large debris generated by the lower cutting knife 41 when cutting. The buffer block is made of thermally conductive material, which can transfer the heat generated by the heat sealing head on the upper template 31 and the lower template 32 to the buffer block to facilitate heating and sealing the slurry distribution pipe.

[0067] Please refer to Figure 4The adjusting frame 33 includes four pillars 331, a movable plate 332 and a top seal 333. The four pillars 331 are symmetrically arranged on both sides of the pipeline guide groove 11 in pairs. The movable plate 332 is installed between the four pillars 331. The cylinder 42 is installed on the top of the movable plate 332. The telescopic end of the cylinder 42 passes through the movable plate 332 and is connected to the cutting knife 41. The upper template 31 is installed at the bottom of the movable plate 332 through a fixed column. The top seal 333 is installed on the top of the four pillars 331. The regulating mechanism 34 is installed in the top seal 333. The regulating mechanism 34 is connected with a screw group, which consists of four screw rods 335. Each of the pillars 331 is provided with the screw rod 335, and the movable plate 332 is movably connected with the screw rod 335.

[0068] The regulating mechanism 34 includes a control motor 341, a pay-off pulley 342 and a driving rope 343. A pay-off pulley 342 is provided on the top of each of the pillars 331, and the driving rope 343 is connected to each of the pay-off pulleys 342 in sequence to form a ring. The control motor 341 is fixedly installed on the top of the top seal 333, and the output end passes through the top seal 333 and is connected to one of the pay-off pulleys 342. Each of the pay-off pulleys 342 is connected to the screw rod 335. Each of the pillars 331 is provided with a slide groove 336 on the side facing the movable plate 332. A ball nut is connected to the movable plate 332, and the ball nut passes through the slide groove 336 and is connected to the screw rod 335.

[0069] When in use, the motor 341 is controlled to drive the pay-off pulley 342 to rotate, and the other three pay-off pulleys 342 are driven to rotate under the action of the driving rope 343, and the screw rod 335 on each pillar 331 is driven to rotate, thereby driving the movable plate 332 to move vertically along the screw rod 335 to adjust the distance between the upper template 31 and the lower template 32.

[0070] After the equipment is started, the slurry pipe to be processed is placed in the pipe guide groove 11. At this time, the components of the adjustment frame 33 are in the initial state. When it is necessary to adjust the position of the upper template 31 to adapt to the height of different slurry pipes or adjust the sealing pressure, the control motor 341 is started, and the control motor 341 drives the wire-releasing pulley 342 connected thereto to rotate. Since the driving rope 343 forms a ring and is connected to each wire-releasing pulley 342 in sequence, the rotation of one wire-releasing pulley 342 will drive the other wire-releasing pulleys 342 to rotate synchronously through the driving rope 343, and the screw rod 335 connected to each wire-releasing pulley 342 will rotate synchronously. When the screw rod 335 rotates, the movable plate 332 connected to the screw rod 335 through the ball nut will Under the action of the screw rod 335, it moves up and down along the direction of the pillar 331, thereby driving the upper template 31 installed at the bottom of the movable plate 332 to rise or fall, and accurately adjust the distance between the upper template 31 and the lower template 32 to meet the sealing requirements of different slurry pipes. The synchronous transmission method can ensure that the movable plate 332 remains horizontal during the up and down movement, avoiding the tilt of the upper template 31 due to inconsistent lifting and lowering of various parts, thereby improving the accuracy of the position adjustment of the upper template 31. When sealing slurry pipes of different diameters, the distance between the upper template 31 and the lower template 32 can be more accurately controlled to ensure uniform sealing pressure, effectively improve the sealing quality, and reduce problems such as leakage caused by uneven sealing pressure.

[0071] Embodiment six:

[0072] Please refer to Figure 4-6 The adjustment component 6 includes a hollow guide rail 61 and a slider 62. The hollow guide rail 61 is fixedly mounted on the extrusion plate 23. The slider 62 is slidably connected to the hollow guide rail 61. The center of the slider 62 is fixedly connected to one end of the positioning pin 221. Locking mechanisms are provided on both sides of the slider 62. A locking groove 66 matching the locking mechanism is provided on the outer wall of the hollow guide rail 61.

[0073] The locking mechanism includes a butterfly handle 63, a fixed shaft 64 and a torsion spring 65. The fixed shaft 64 is fixedly installed on both sides of the slider 62. The butterfly handle 63 is rotatably installed on the fixed shaft 64. The torsion spring 65 is also sleeved on the fixed shaft 64. The fixed end of the torsion spring 65 is fixedly connected to the outer wall of the slider 62, and the movable end of the torsion spring 65 is tightly fixed to the outer wall of the butterfly handle 63. A locking block matching the locking groove 66 is provided on the side of the butterfly handle 63 close to the hollow guide rail 61.

[0074] Existing pulping equipment is often difficult to adapt to blood bags of various specifications. In this equipment, a plurality of positioning pins 221 are arranged on the squeezing plate 22, and each positioning pin 221 is connected to an adjustment component 6. Through the adjustment component 6, the operator can flexibly adjust the horizontal position of the positioning pin 221 on the squeezing plate 22 according to the different hanging hole positions on the blood bag. Specifically, the torsion spring 65 is squeezed by pinching the butterfly handle 63 and rotating it around the fixed shaft 64, so that the locking block is disengaged from the locking groove 66, thereby releasing the restriction on the slider 62, and pulling the positioning pin 221 to move along the hollow guide rail 61 to adjust the position. This design enables the equipment to adapt to blood bags of various specifications, greatly expanding the scope of application of the equipment, reducing the need to replace the pulping equipment or perform complex adjustments due to different specifications of blood bags, and improving work efficiency. The positioning pin 221 can firmly fix the blood bag on the squeezing plate 22, and effectively prevent the blood bag from shifting due to squeezing during the pulping process.
