Description

Technical Field

[0001] This utility model belongs to the field of ointment making machine technology, specifically relating to a vacuum suction device for ointment making machine. Background Technology

[0002] Cream-making machines are widely used in the cosmetics, pharmaceutical, and food industries for mixing, stirring, and filling high-viscosity creams. During the cream-making process, a vacuum suction device is typically used to extract the stirred cream from the mixing tank to prevent outside air from entering and affecting the cream quality. Different pastes have different densities and viscosities. If the outlet is too high, the weight of the paste will increase the load on the vacuum pump, resulting in reduced suction efficiency and even affecting the life of the vacuum pump. Some pastes may still contain tiny air bubbles, affecting the uniformity and storage stability of the final product. To address this, we have designed a vacuum suction device for paste making machines to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1-7 A vacuum suction device for a paste making machine includes a suction box 1, a top sealing cover 2 on the top of the suction box 1, a rotatable L-shaped conveying pipe 5 inside the suction box 1, a soft conveying pipe 6 at one end of the L-shaped conveying pipe 5 and located outside the suction box 1, and a liftable vibrating rod 4 inside the suction box 1. A rotating mechanism for rotating the L-shaped conveying pipe 5 is provided on the outside of the suction box 1; The material suction box 1 is equipped with a lifting mechanism for raising and lowering the vibrating rod 4; A vacuum pump 3 is installed on the outside of the suction box 1. The vacuum pump 3 is connected to the top sealing cover 2 through a pipe. A discharge pipe is installed at the bottom of the suction box 1. A solenoid valve is fixed on the outside of the discharge pipe. The solenoid valve can control the closing state inside the discharge pipe. The operation of the vacuum pump 3 can control the air pressure inside the suction box 1. The rotating mechanism includes a vertical hydraulic cylinder 7, which is fixed to the outside of the suction box 1. The output end of the vertical hydraulic cylinder 7 is rotatably connected to a horizontal connecting rod 8. The outside of the horizontal connecting rod 8 is rotatably connected to an oblique rotating rod 10. The bottom of the oblique rotating rod 10 is rotatably connected to an oblique rotating block 11 through a pin. The oblique rotating block 11 is sleeved on the outside of the L-shaped conveying pipe 5 and is fixedly connected to the L-shaped conveying pipe 5. A vertical slider 9 is fixed on the side of the horizontal connecting rod 8 near the suction box 1. A vertical groove is provided on the outside of the suction box 1. The vertical slider 9 is located inside the vertical groove and is slidably connected to the suction box 1 through the vertical groove. The vertical groove allows the vertical slider 9 to slide vertically on the outside of the suction box 1, thereby guiding the vertical lifting trajectory of the horizontal connecting rod 8. An L-shaped support column 12 is also sleeved on the outside of the L-shaped conveying pipe 5. The L-shaped support column 12 is close to the side of the suction box 1 and is fixedly connected to the suction box 1. The L-shaped support column 12 and the L-shaped conveying pipe 5 are rotatably connected by a bearing. The soft conveying pipe 6 is located inside the L-shaped support column 12 and is fixedly connected to the L-shaped support column 12, so that the L-shaped conveying pipe 5 can rotate inside the L-shaped support column 12, and the port where the soft conveying pipe 6 and the L-shaped conveying pipe 5 are connected can be fixed. Here, the operation of the vertical hydraulic cylinder 7 enables the horizontal connecting rod 8 to be raised and lowered vertically. The raising and lowering of the horizontal connecting rod 8 enables the vertical slider 9 to slide vertically inside the suction box 1. The raising and lowering of the horizontal connecting rod 8, through the inclined rotating rod 10 and the inclined rotating block 11, enables the L-shaped conveying pipe 5 to rotate inside the suction box 1, thereby allowing the height position of the discharge port at one end of the L-shaped conveying pipe 5 to be adjusted.

[0018] The lifting mechanism includes an L-shaped mounting bracket 13. The top of the top sealing cover 2 is fixed with an L-shaped mounting bracket 13. One end of the L-shaped mounting bracket 13 is bolted with a transverse drive motor 14. The output end of the transverse drive motor 14 is fixed with a transverse threaded rod 15. An arc-shaped connecting block 16 is threaded to the outer side of the transverse threaded rod 15. A vibration drive motor 17 is fixed to the bottom of the arc-shaped connecting block 16. The vibration drive motor 17 is located inside the L-shaped mounting bracket 13 and is slidably connected to the L-shaped mounting bracket 13. The output end of the vibration drive motor 17 is fixed with a vibration output pipe 18. The bottom of the vibration output pipe 18 is connected to the vibrating rod 4. An L-shaped support block 20 is fixed at one end of the L-shaped mounting bracket 13 away from the transverse drive motor 14. Two circular guide rollers 19 are rotatably connected inside the L-shaped support block 20. The two circular guide rollers 19 are located on both sides of the vibratory output pipe 18. The setting of the two circular guide rollers 19 can limit the lifting position of the vibratory output pipe 18. The bottom of the vibratory drive motor 17 is fixed with a horizontal slider, and the interior of the L-shaped mounting bracket 13 is provided with a horizontal sliding groove. The vibratory drive motor 17 and the L-shaped mounting bracket 13 are slidably connected through the horizontal slider and the horizontal sliding groove. The horizontal slider and the horizontal sliding groove enable the vibratory drive motor 17 to slide laterally inside the L-shaped mounting bracket 13. The top sealing cover 2 is equipped with a V-shaped sealing ring inside. The vibration output pipe 18 is located inside the V-shaped sealing ring and is slidably connected with the V-shaped sealing ring. Through the setting of the V-shaped sealing ring, it is self-tightened by the medium pressure and can withstand high pressure, thereby preventing leakage between the V-shaped sealing ring and the vibration output pipe 18.

[0019] Here, the operation of the transverse drive motor 14 causes the transverse threaded rod 15 to rotate. The rotation of the transverse threaded rod 15 causes the arc-shaped connecting block 16 to move laterally, which in turn causes the vibration drive motor 17 to move laterally inside the L-shaped mounting bracket 13. The movement of the vibration drive motor 17 causes the vibrating rod 4 to move vertically up and down inside the suction box 1 through the vibration output pipe 18. The operation of the vibration drive motor 17 causes the vibrating rod 4 to vibrate through the vibration output pipe 18, which in turn causes the paste inside the suction box 1 to be vibrated, reducing the air inside the paste and increasing the storage capacity of the suction box 1. Through the gravity of the vibrating rod 4, the movement of the vibration drive motor 17 causes the vibration output pipe 18 to slide inside the V-shaped sealing ring. When the vibration output pipe 18 is stationary, the vibration output pipe 18 and the V-shaped sealing ring can maintain a sealed state.

[0020] Working principle: The operation of the vertical hydraulic cylinder 7 enables the horizontal connecting rod 8 to be raised and lowered vertically. The raising and lowering of the horizontal connecting rod 8 enables the vertical slider 9 to slide vertically inside the suction box 1. The raising and lowering of the horizontal connecting rod 8, through the inclined rotating rod 10 and the inclined rotating block 11, enables the L-shaped conveying pipe 5 to rotate inside the suction box 1, thereby allowing the height position of the discharge port at one end of the L-shaped conveying pipe 5 to be adjusted. By operating the vacuum pump 3, the air pressure inside the suction box 1 can be controlled. When the pressure inside the suction box 1 is too high, the soft conveying pipe 6 is inserted into the interior of the paste. Through the air pressure difference inside the suction box 1, the paste can be injected into the interior of the suction box 1 through the L-shaped conveying pipe 5. When the paste volume inside the L-shaped conveying pipe 5 is too large, the outlet of the L-shaped conveying pipe 5 is raised by the vertical hydraulic cylinder 7. Conversely, when the paste height inside the L-shaped conveying pipe 5 is low, the position of the outlet of the L-shaped conveying pipe 5 is lowered to reduce the operating burden of the vibrating rod 4. The lowest position of the outlet of the L-shaped conveying pipe 5 is when the L-shaped conveying pipe 5 is parallel to the horizontal plane.

[0021] The operation of the transverse drive motor 14 enables the transverse threaded rod 15 to rotate. The rotation of the transverse threaded rod 15 enables the arc-shaped connecting block 16 to move laterally, thereby enabling the vibration drive motor 17 to move laterally inside the L-shaped mounting bracket 13. The movement of the vibration drive motor 17, through the vibration output pipe 18, enables the vibrating rod 4 to move vertically up and down inside the suction box 1. The operation of the vibration drive motor 17, through the vibration output pipe 18, enables the vibrating rod 4 to vibrate, thereby enabling the paste inside the suction box 1 to be vibrated, reducing the air inside the paste and improving the storage capacity of the suction box 1. Through the gravity of the vibrating rod 4, the movement of the vibration drive motor 17 enables the vibration output pipe 18 to slide inside the V-shaped sealing ring. When the vibration output pipe 18 is stationary, the vibration output pipe 18 and the V-shaped sealing ring can maintain a sealed state.
