[0034] The following is in conjunction with the appendix Figure 1-7 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.
[0035] This utility model discloses an ultrafiltration membrane vibration dispensing device.
[0036] Reference Figures 1-7 An ultrafiltration membrane vibration dispensing device includes a base 1, on which a lifting and rotating assembly 2 and a vibration assembly 3 are mounted. The lifting and rotating assembly 2 is connected to a floating clamp assembly 4 and a dispensing control assembly 5. The floating clamp assembly 4 is used to fix the ultrafiltration membrane 6, and the lifting and rotating assembly 2 is used to control the lifting and rotating of the ultrafiltration membrane 6, so that the ultrafiltration membrane fixtures 7 at both ends of the ultrafiltration membrane 6 are tightly attached to the vibration assembly 3. The dispensing control assembly 5 is used to control the dispensing speed and flow rate of the ultrafiltration membrane 6, and the vibration assembly 3 is used to provide excitation force for the dispensing process, eliminate air bubbles in the dispensing solution, and realize static dispensing of the ultrafiltration membrane 6. The device is highly automated and saves time and labor.
[0037] The lifting and rotating assembly 2 includes a support frame 21, a lifting frame 22, a lifting cylinder 23, and a rotary support mechanism 24. The support frame 21 is bolted to the base 1, and the lifting frame 22 can be raised and lowered along the support frame 21. The cylinder seat of the lifting cylinder 23 is fixedly connected to the base 1, and the piston rod of the lifting cylinder 23 is fixedly connected to the lifting frame 22. When the piston rod of the lifting cylinder 23 extends or retracts, it can drive the lifting frame 22 to rise and fall along the support frame 21.
[0038] The rotary support mechanism 24 is connected to both the lifting frame 22 and the floating clamp assembly 4. The rotary support mechanism 24 is used to drive the ultrafiltration membrane 6 to rotate, so that the ultrafiltration membrane fixtures 7 at both ends of the ultrafiltration membrane 6 are tightly attached to the vibration assembly 3, thereby realizing that the vibration assembly 3 performs static glue injection on both ends of the ultrafiltration membrane 6.
[0039] The rotary support mechanism 24 includes a servo motor (not shown in the figure), a rotating shaft 241, a worm gear 242, and a worm 243. The servo motor is fixedly connected to the lifting frame 22, and the output shaft of the servo motor is fixedly connected to the worm 243. The worm 243 meshes with the worm gear 242, and the worm gear 242 is sleeved on the outside of the rotating shaft 241. The rotating shaft 241 is rotatably connected to the frame and connected to the floating clamp assembly 4. Starting the servo motor drives the worm 243 to rotate, which in turn drives the worm gear 242 to rotate, which in turn drives the rotating shaft 241 to rotate, which in turn drives the floating clamp assembly 4 to rotate, thereby achieving the rotation of the ultrafiltration membrane 6. By controlling the forward and reverse rotation of the servo motor, the floating clamp assembly 4 can rotate by ±90°. Sensors can be installed to detect whether the rotation angle is correct, so that the ultrafiltration membrane fixtures 7 at both ends of the ultrafiltration membrane 6 can be tightly attached to the vibration assembly 3.
[0040] The lifting and rotating assembly 2 also includes four sets of lifting guide rails 25, which are fixed to the support frame 21. The lifting frame 22 is slidably connected to the lifting guide rails 25. During the lifting and lowering process, the lifting frame 22 can slide along the lifting guide rails 25. The lifting guide rails 25 can guide the lifting and lowering of the lifting frame 22, thereby improving the stability of the lifting and lowering of the lifting frame 22 and thus improving the stability of the lifting and lowering of the ultrafiltration membrane 6.
[0041] The floating clamping assembly 4 is provided in two sets, located on both sides of the lifting and rotating assembly 2. Each set of the floating clamping assembly 4 includes an inner frame 41 and a clamping mechanism 42. The inner frame 41 is fixedly connected to the rotating shaft 241 in the lifting and rotating assembly 2. Each inner frame 41 is fixedly provided with two placement racks 43, which are used to place the ultrafiltration membrane 6. The clamping mechanism 42 is provided on the inner frame 41 and is used to clamp the ultrafiltration membrane 6. After the four ultrafiltration membranes 6 are placed on the four placement racks 43 respectively, the clamping mechanism 42 clamps the ultrafiltration membranes 6, so that the lifting and rotating of the four ultrafiltration membranes 6 can be performed simultaneously, improving efficiency.
[0042] The clamping mechanism 42 includes a clamping cylinder 421 and a clamping frame 422. The cylinder seat of the clamping cylinder 421 is hinged to the inner frame 41, and the piston rod of the clamping cylinder 421 is hinged to the clamping frame 422. The clamping frame 422 is rotatably connected to one side of the inner frame 41 via a pin. By extending and retracting the piston rod of the clamping cylinder 421, the clamping frame 422 is driven to swing, allowing for the placement and removal of the ultrafiltration membrane 6.
[0043] The floating clamp assembly 4 also includes an outer plate 44 and a floating spring 45. The outer plate 44 is bolted to the outside of the inner frame 41, and outer plates 44 are provided on both sides of the inner frame 41. The floating spring 45 is located between the inner frame 41 and the outer plate 44, and its two ends are fixedly connected to the inner frame 41 and the outer plate 44, respectively. The floating spring 45 can buffer the excitation force, minimizing the transmission of the excitation force to the inner structure.
[0044] The floating clamp assembly 4 also includes a limiting block 46 fixed on the placement frame 43. The limiting block 46 is made of nylon and is used to restrict the axial movement of the ultrafiltration membrane 6. The limiting block 46 contacts the ultrafiltration membrane 6 to restrict the axial movement of the ultrafiltration membrane 6.
[0045] The vibration assembly 3 is provided in two sets, corresponding to two sets of floating clamping assemblies 4 respectively. Each set of vibration assembly 3 includes a vibrating cylinder 31, an upper vibrating seat 32, a spring 33, a lower vibrating seat 34, and a vibrating motor 35. The lower vibrating seat 34 is bolted to the base 1, and the spring 33 is located between the upper vibrating seat 32 and the lower vibrating seat 34. There are four vibrating cylinders 31 in total, arranged in pairs, corresponding to the two sets of floating clamping assemblies 4 respectively, and the positions of the four vibrating cylinders 31 correspond to the four placement frames 43.
[0046] The vibrating cylinder 31 is bolted to the vibrating upper seat 32, and the vibrating motor 35 is connected to the vibrating upper seat 32. The vibrating motor 35 generates an excitation force, the magnitude of which can be adjusted by regulating the frequency of the vibrating motor 35. The spring 33 ensures that the excitation force is transmitted upwards, allowing it to be transferred through the vibrating cylinder 31 to the ultrafiltration membrane fixture 7, thus eliminating air bubbles in the adhesive solution.
[0047] The vibration assembly 3 also includes vibration columns 36. Each set of vibration assemblies 3 includes four vibration columns 36 and four springs 33, with each vibration column 36 and spring 33 corresponding to the other. The vibration columns 36 are fixed between the lower vibration seat 34 and the springs 33. The vibration motor 35 is bolted to the bottom of the upper vibration seat 32. The vibration columns 36 can raise the upper vibration seat 32, thereby providing installation space for the vibration motor 35.
[0048] The glue dispensing control assembly 5 includes a glue tank bracket 51 and a mounting plate 52, both of which are mounted on the support frame 21. Four glue tanks 53 are mounted on the glue tank bracket 51 for dispensing glue to four ultrafiltration membranes 6. Each glue tank 53 has a lid 54, and each lid 54 has an air inlet 551. A piston 56 is slidably mounted inside each glue tank 53. Figure 6 Only one of the glue barrels 53 is shown (piston 56 is shown), and each glue barrel 53 has a glue outlet 552 at the bottom. The glue barrel 53 has a piston structure. After the glue is injected into the glue barrel 53, the piston 56 is pushed forward by compressed air, which can squeeze the glue in the glue barrel 53 out of the glue outlet 552.
[0049] Four solenoid valves 57 are installed on the mounting plate 52, corresponding to four glue tanks 53. Each solenoid valve 57 is connected to the air inlet 551 of the glue tank 53 via a pipe. Each pipe is equipped with a pressure regulating valve 58, and each solenoid valve 57 is equipped with a throttling speed regulating valve 59. Both the throttling speed regulating valve 59 and the pressure regulating valve 58 are mounted on the mounting plate 52. An external hose connects to the glue outlet 552 of the glue tank 53, and compressed air pushes the piston 56 forward, squeezing the glue from the glue tank 53 into the glue injection hole 8 of the ultrafiltration membrane fixture 7. The glue injection speed and flow rate of the ultrafiltration membrane 6 can be controlled by adjusting the throttling speed regulating valve 59 and the pressure regulating valve 58.
[0050] The implementation principle of the ultrafiltration membrane vibration dispensing device of this utility model is as follows: After the ultrafiltration membrane fixtures 7 are fixed at both ends of the ultrafiltration membrane 6, the ultrafiltration membrane 6 is fixed by the floating clamping assembly 4. At this time, the ultrafiltration membrane 6 is in a horizontal state. The dispensing control assembly 5 injects the glue into one end of the ultrafiltration membrane fixture 7 through the dispensing hole 8, thereby controlling the dispensing speed and flow rate of the ultrafiltration membrane 6. After the dispensing is completed, the lifting and rotating assembly 2 controls the lifting and rotating of the ultrafiltration membrane 6 and the forward rotation by 90°, so that the dispensing end of the ultrafiltration membrane 6 is tightly attached to the vibration assembly 3. The vibration assembly 3 provides excitation force for the dispensing process, eliminates air bubbles in the glue, and the vibration 3... Stop after 00 seconds and let stand for 4 hours to achieve static glue injection of ultrafiltration membrane 6; then, control the lifting and rotating component 2 to raise and lower the ultrafiltration membrane 6 and rotate it 90° in the opposite direction to a horizontal state. The glue injection control component 5 injects the glue into the ultrafiltration membrane fixture 7 at the other end through the glue injection hole 8. After the glue injection is completed, control the lifting and rotating component 2 to raise and lower the ultrafiltration membrane 6 and continue to rotate it 90° in the opposite direction so that the ultrafiltration membrane fixture 7 at the end of the ultrafiltration membrane 6, which has just been glued, is in close contact with the vibration component 3; the vibration component 3 provides excitation force for the glue injection process to eliminate air bubbles in the glue. Stop after 300 seconds of vibration and let stand for 4 hours to complete the static glue injection of ultrafiltration membrane 6.
