Description

Technical Field

[0001] This application relates to the field of blood recycling technology, specifically a blood recycling tank shell clamping and rotating device. Background Technology

[0002] Blood salvage is a technique that uses specialized equipment to collect, process, and reinfuse blood that flows out of a patient during or after surgery. It is mainly used to reduce allogeneic blood transfusions and their associated risks, and has important application value in clinical surgery.

[0003] In the field of medical device manufacturing, the clamping and rotation of blood recycling canister shells is a critical process. Currently, the industry commonly uses manual operation or simple mechanical clamps, which have significant drawbacks: traditional dual-drive cylinder spacing adjustment relies on manual slide rails, making dynamic synchronous adjustment impossible; furthermore, the rotation direction of the clamping components is fixed, requiring manual handling and adjustment of the shell's posture when processing at multiple angles, resulting in low efficiency and safety hazards. Therefore, there is an urgent need for an efficient and precise clamping and rotation device to meet production requirements. To this end, a blood recycling canister shell clamping and rotation device is provided. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a blood recycling tank shell clamping and rotating device with precise cylinder spacing adjustment and multi-angle rotation functions.

[0005] To achieve the above objectives, this application provides the following technical solution: a blood recycling tank shell clamping and rotating device, comprising a rotating assembly, a clamping assembly, and a driving cylinder. The clamping assembly is disposed on the upper end of the rotating assembly, and the driving cylinder is disposed on the upper end of the clamping assembly. Two sets of driving cylinders are symmetrically arranged on the upper end of the clamping assembly. Each set of clamping assemblies has a replacement mechanism at its opposite ends, and each set of replacement mechanisms has a clamping block at its opposite ends. The rotating assembly includes a support base, and a forward and reverse motor is disposed inside the support base. The output end of the forward and reverse motor is rotatably connected to the upper end of the support base, and the output end of the forward and reverse motor is fixedly connected to a rotating... The disc, the clamping assembly includes a dual-axis motor, the dual-axis motor is fixedly connected inside the turntable, both ends of the output shaft of the dual-axis motor are fixedly connected to threaded columns, the two sets of threaded columns are rotatably connected to the turntable at the opposite end, the surfaces of the two sets of threaded columns are threaded with threaded caps, the upper ends of the two sets of threaded caps are fixedly connected to connecting rods, the upper surface of the turntable has a limit groove, the connecting rods are movably connected inside the limit groove, the upper surface of the turntable is fixedly connected to a support platform, the upper surfaces of the two sets of connecting rods are fixedly connected to movable shells, the movable shells and the support platform are interlocked, and the two sets of drive cylinders are fixedly connected to the upper surfaces of the two sets of movable shells.

[0006] With the above scheme, two sets of drive cylinders are symmetrically distributed on the upper end of the clamping assembly. The spacing is synchronously adjusted by the threaded column driven by the dual-axis motor to ensure that the clamping force is evenly distributed and to avoid deformation caused by the eccentric force on the shell. The forward and reverse motors drive the turntable to achieve rotation at any angle, which can meet the multi-angle processing needs of the shell, reduce manual handling procedures, and improve production efficiency.

[0007] Furthermore, a first groove is formed on the lower surface of the turntable, and a second groove is formed on the upper surface of the support base. Rolling balls are tumblingly connected inside the first and second grooves. Multiple sets of rolling balls are provided and are evenly distributed inside the first and second grooves.

[0008] With the above solution, the turntable and the support base are connected by rolling balls, which reduces the rotational friction torque and ensures smooth and uninterrupted operation when driven by the forward and reverse motors.

[0009] Furthermore, the replacement mechanism includes a U-shaped limiting sleeve. Two sets of the U-shaped limiting sleeves are fixedly connected to the opposite ends of the two sets of driving cylinders. A locking block is movably connected inside the U-shaped limiting sleeve. The upper end of the U-shaped limiting sleeve has a first through hole and a third through hole. The inside of the locking block has a second through hole and a fourth through hole. A first locking rod passes through the first through hole and the second through hole. A second locking rod passes through the third through hole and the fourth through hole. The lower surface inside the U-shaped limiting sleeve has a first locking groove and a second locking groove. The lower end of the first locking rod passes through the first locking groove. The lower end of the second locking rod passes through the second locking groove. A movable plate is fixedly connected to the upper ends of the first locking rod and the upper surface of the first locking rod. A spring passes through the upper surface of the first locking rod. The upper end of the spring is fixedly connected to the lower surface of the movable plate. The lower end of the spring is fixedly connected to the upper surface of the U-shaped limiting sleeve. A handle is provided on the upper surface of the movable plate. Two sets of clamping blocks are fixedly connected to the opposite ends of the two sets of locking blocks.

[0010] The above solution utilizes a replacement mechanism consisting of a U-shaped limiting sleeve, a locking block, and a spring. By pulling the handle, the clamping block can be replaced without tools, which improves efficiency compared to the traditional bolt connection method and can quickly adapt to different sized shells.

[0011] Furthermore, the dual-axis motor is a servo motor.

[0012] The above scheme uses a servo motor to drive the threaded column to rotate, which in turn drives the drive cylinder to move synchronously through the threaded cap, resulting in high positioning accuracy.

[0013] Furthermore, the clamping block is made of high-strength nylon.

[0014] The above solution utilizes high-strength nylon material, which has high hardness and wear resistance, preventing scratches on the metal shell surface and making it suitable for medical-grade surface requirements.

[0015] Furthermore, a set of wheels is fixedly connected to the lower surface of the support base, and brake pads are provided on the side of the set of wheels. There are four sets of wheels, which are arranged in a rectangular shape at the lower end of the support base.

[0016] With the above solution, the four sets of wheel support devices can move freely. Compared with the traditional fixed device, the station adjustment time is shortened and the brake pads are easy to fix.

[0017] Furthermore, a controller is fixedly connected to the front side of the support base. The controller includes a touch screen and physical buttons for inputting parameters and triggering action commands.

[0018] With the above solution, the touchscreen can store multiple sets of shell model parameters, which can be switched with one click when called, reducing the time spent on repeated input and improving the efficiency of model changeover.

[0019] Furthermore, the handle surface is provided with an elastic protective pad.

[0020] The above solution improves the comfort of manually replacing the clamping block by adding an elastic protective pad.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This blood recycling canister shell clamping and rotating device uses a dual-axis motor to drive a transmission structure of threaded columns and threaded caps, enabling precise adjustment of the distance between two sets of drive cylinders. Compared with the positioning error of traditional manual slide rails, it significantly improves the adaptability of shells of different diameters. The positive and negative motors in the support base drive the clamping components to rotate at any angle through a turntable, which can meet the multi-angle processing needs such as side welding and top spraying of the shell. It completely eliminates the process of manual handling and posture adjustment, reduces the risk of shell scratches caused by handling, and shortens the processing time. Through the replacement mechanism composed of U-shaped limit sleeve, card block and spring, the clamping block can be replaced without tools by pulling the handle. Compared with the traditional bolt connection method, the efficiency is improved and it can quickly adapt to shells of different sizes. Attached Figure Description

Inside the turntable 103, threaded caps 202 are threadedly connected to the surfaces of two sets of threaded columns 206. Connecting rods 203 are fixedly connected to the upper ends of the two sets of threaded caps 202. Limiting grooves 104 are formed on the upper surface of the turntable 103, and the connecting rods 203 are movably connected inside the limiting grooves 104. Support platforms 204 are fixedly connected to the upper surface of the turntable 103. Movable shells 205 are fixedly connected to the upper surfaces of the two sets of connecting rods 203. The movable shells 205 and the support platforms 204 are interlocked. Two sets of drive cylinders 3 are fixedly connected to the upper surfaces of the two sets of movable shells 205. The two sets of drive cylinders 3 are symmetrically distributed on the upper end of the clamping assembly 2. The threaded columns 206 are synchronously adjusted by the dual-axis motor 201 to ensure uniform distribution of clamping force and avoid deformation caused by eccentric force on the shell. The forward and reverse motors 102 drive the turntable 103 to achieve rotation at any angle, meet the multi-angle processing requirements of the shell, reduce manual handling procedures, and improve production efficiency.

[0032] Please see Figure 1 , Figure 3 and Figure 5The turntable 103 has a first groove 105 on its lower surface and a second groove 106 on its upper surface. Rolling balls 107 are rolled inside the first and second grooves 105 and 106, with multiple sets of rolling balls 107 evenly distributed within them. The replacement mechanism 4 includes a U-shaped limiting sleeve 401. Two sets of U-shaped limiting sleeves 401 are fixedly connected to the opposite ends of two sets of drive cylinders 3. The part is movably connected to a locking block 402. A first through hole 403 and a third through hole 410 are provided at the upper end of the U-shaped limiting sleeve 401.

The turntable 103 and the support base 101 are connected by a rolling ball 107 to reduce the rotational friction torque and ensure that the forward and reverse motors 102 drive smoothly without jamming. Through the replacement mechanism 4 composed of the U-shaped limiting sleeve 401, the locking blocks 402 and the spring 407, the clamping blocks 8 can be replaced without tools by pulling the handle 409. Compared with the traditional bolt connection method, the efficiency is improved and different sizes of shells can be quickly adapted.

[0033] Please see Figure 1 and Figure 2The dual-axis motor 201 is a servo motor. The clamping block 8 is made of high-strength nylon. A wheel set 5 is fixedly connected to the lower surface of the support base 101. Brake pads 6 are provided on the side of the wheel set 5. There are four sets of wheels 5, which are rectangularly arranged at the lower end of the support base 101. A controller 7 is fixedly connected to the front of the support base 101. The controller 7 includes a touch screen and physical buttons for inputting parameters and triggering action commands. An elastic protective pad is provided on the surface of the handle 409. The servo motor drives the threaded column 206 to rotate, which drives the drive cylinder 3 to move synchronously through the threaded cap 202. The positioning accuracy is high. The high-strength nylon material has high hardness and wear resistance, avoiding scratches on the surface of the metal shell. It is suitable for medical-grade surface requirements. The four sets of wheel sets 5 support the free movement of the device. Compared with the traditional fixed device, the station adjustment time is shortened. The brake pads 6 facilitate the fixing of the device. The touch screen can store more than one set of shell model parameters. When recalling, one-click switching is used to reduce repetitive input time and improve the efficiency of model changeover. The setting of the elastic protective pad improves the comfort of manual replacement of the clamping block 8.

[0034] In this embodiment, the transmission structure of the threaded column 206 and threaded cap 202 driven by the dual-axis motor 201 enables precise adjustment of the distance between the two sets of drive cylinders 3. Compared with the positioning error of the traditional manual slide rail, it significantly improves the adaptability of shells of different diameters. The forward and reverse motors 102 in the support base 101 drive the clamping component 2 to rotate at any angle through the turntable 103, which can meet the multi-angle processing requirements such as side welding and top spraying of the shell. It completely eliminates the manual handling and posture adjustment process, reduces the risk of shell scratches caused by handling, and shortens the processing time. Through the replacement mechanism 4 composed of U-shaped limit sleeve 401, card block 402 and spring 407, the clamping block 8 can be replaced without tools by pulling the handle 409. Compared with the traditional bolt connection method, the efficiency is improved and it can quickly adapt to shells of different sizes.

[0035] The working principle of the above embodiment is as follows: The replacement mechanism 4 consists of a U-shaped limiting sleeve 401, a locking block 402, a first locking rod 405, a second locking rod 412, and a spring 407. The clamping block 8 is fixed to the front end of the locking block 402 and is connected to the drive cylinder 3 through a double locking structure. The locking block 402 can move axially within the U-shaped limiting sleeve 401. With the elastic preload of the spring 407, the clamping block 8 is kept locked when subjected to radial force. For small-sized housings, a narrow clamping block 8 is selected. After quick installation by the spring 407, the dual-axis motor 201 drives the threaded column 206 to retract, reducing the distance between the two drive cylinders 3 to the appropriate size. For large-sized housings, a wide clamping block 8 is replaced, and the dual-axis motor 201 drives the threaded column 206 to extend, increasing the distance between the two drive cylinders 3. Pulling handle 409 upwards moves movable plate 408 upwards. First locking lever 405 and second locking lever 412 simultaneously disengage from the first locking groove 406, second locking groove 413, second through hole 404, and fourth through hole 411 of U-shaped limiting sleeve 401 and locking block 402. Spring 407 is stretched, pulling locking block 402 forward. Old clamping block 8 disengages from U-shaped limiting sleeve 401 along with locking block 402. Align the back of clamping block 8 (fitted to the new housing size) with locking block 402 on the U-shaped limiting sleeve 401 and insert it until the bottom of locking block 402 contacts the inner bottom surface of U-shaped limiting sleeve 401. Release handle 409, spring 407 resets, and moves movable plate 408 downwards. First locking lever 405 and second locking lever 412 respectively engage in first locking groove 406. After locking the second locking slot 413 and replacing the clamping block 8 with the corresponding size, the diameter parameter of the housing is input through the touch screen of the controller 7. The dual-axis motor 201 is started, driving the threaded column 206 to rotate. The threaded cap 202 moves along the threaded column 206 and pushes the movable housing 205 to slide on the support platform 204 through the connecting rod 203. The distance between the two drive cylinders 3 is adjusted, and the limit groove 104 guides the connecting rod 203 to ensure that the cylinders on both sides move synchronously. After the clamping block 8 is replaced and the distance is adjusted, the drive cylinder 3 pushes the clamping block 8 to clamp the housing. By controlling the forward and reverse motors 102 to drive the clamping assembly 2 to rotate at any angle, it can meet the multi-angle processing requirements such as side welding and top spraying of the housing, and completely eliminate the manual handling and posture adjustment process.
