Description

Technical Field

[0001] This utility model relates to the field of filling machine technology, specifically to an anti-drip precision filling machine. Background Technology

[0002] Precision filling machines are widely used in pharmaceutical, food, chemical, and other industries, primarily for accurately filling liquids, viscous materials, or other fluids into containers. These machines are typically equipped with high-precision control systems and optimized filling heads to ensure highly accurate filling volumes each time. However, in actual operation, liquid dripping remains a common problem for traditional precision filling equipment, especially when handling high-viscosity or volatile liquids. This dripping phenomenon is particularly pronounced, affecting not only filling efficiency and accuracy but also potentially leading to environmental pollution and waste of raw materials.

[0003] In current precision filling equipment, especially when filling high-viscosity or highly residual liquids, dripping often occurs at the end of the filling process. This results in some liquid remaining in the pipeline or outlet. With the influence of gravity or changes in system pressure, this residual liquid continues to flow out slowly, causing raw material loss and environmental pollution. In addition, at the beginning of the filling process, the liquid usually enters the container under high pressure, which can easily cause a strong impact on the bottle mouth, leading to liquid splashing. This impact effect is more pronounced when the container is not completely filled, which can easily cause liquid to overflow from the bottle mouth, resulting in resource waste and cleaning problems. Therefore, we propose an anti-drip precision filling machine to overcome the above defects. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a drip-proof precision filling machine.

[0005] The technical implementation scheme of this utility model is as follows: A drip-proof precision filling machine includes a chassis, a door panel, and a storage bin. The chassis is the main assembly body of the filling machine. Door panels are symmetrically hinged to the front opening of the chassis. An installation plate is fixedly connected to the center of the chassis, and a storage bin is mounted on the installation plate for storing filling raw materials. The machine also includes a support frame fixedly installed at the bottom of the chassis. An electric push rod is fixedly mounted on the support frame via a bracket. The piston rod of the electric push rod faces downward and is fixedly connected to an installation frame. A filling nozzle is mounted on the installation frame.

A sliding frame is slidably connected to the outer shell of the filling nozzle via a groove. The sliding frame and the connecting rods are slidably engaged. The sliding frame is located at the nozzle of the filling nozzle. A pressure ring is fixedly connected to the bottom of the sliding frame. The pressure ring is located directly below the nozzle of the filling nozzle. A spring is fitted around the connecting rod between the mounting frame and the sliding frame. A vacuum component connected to the filling nozzle is also provided on the mounting plate. The vacuum component is used to suction the remaining filling material at the nozzle of the filling nozzle under negative pressure.

[0006] More preferably, the vacuum component includes a vacuum tube, a vacuum chamber, and a vacuum pump. The vacuum chamber and the vacuum pump are fixedly mounted on the mounting plate. The vacuum chamber and the vacuum pump are connected. The vacuum pump is connected to the nozzle of the filling nozzle through the vacuum tube. The vacuum pump is used to generate negative pressure at the nozzle of the filling nozzle.

[0007] More preferably, the bottom surface of the pressure ring is provided with a rubber ring, and both the pressure ring and the rubber ring have openings in the middle for the filling nozzle to pass through. The rubber ring is used to improve the sealing performance of the pressure ring cap on the filling bottle.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] A drip-proof precision filling machine, such as Figures 1-5 As shown, the machine includes a chassis 1, a door panel 101, and a storage bin 41. The chassis 1 is the main assembly body of the filling machine. The door panel 101 is symmetrically hinged to the front opening of the chassis 1. An installation plate 102 is fixedly connected to the middle of the chassis 1. The storage bin 41 is mounted on the installation plate 102 and is used to store the filling raw materials. The machine also includes a support frame 2 fixedly installed at the bottom of the chassis 1. An electric push rod 3 is fixedly installed on the support frame 2 via a bracket 31. The piston rod of the electric push rod 3 faces downward and is fixedly connected to an installation frame 32. A filling nozzle 4 is mounted on the installation frame 32. The storage bin 41 is connected to the filling nozzle 4 via a pipe. Connecting rods 61 are fixedly installed on both sides of the outer shell of the filling nozzle 4. A sliding frame 6 is slidably connected to the outer shell of the filling nozzle 4 via a sliding groove 7. The sliding frame 6 and the connecting rods 61 are slidably engaged. The sliding frame 6 is located at the nozzle of the filling nozzle 4. A pressure ring 51 is fixedly connected to the bottom of the frame 6. The pressure ring 51 is located directly below the nozzle of the filling nozzle 4. A spring 8 is sleeved on the connecting rod 61 between the mounting frame 32 and the sliding frame 6. A vacuum component connected to the filling nozzle 4 is also provided on the mounting plate 102. The vacuum component is used to suction the residual filling material at the nozzle of the filling nozzle 4 under negative pressure. When the electric push rod 3 drives the filling nozzle 4 on the mounting frame 32 to press down to the filling bottle 9, the pressure ring 51 below the filling nozzle 4 will first contact the bottle mouth of the filling bottle 9. As the electric push rod 3 continues to press down, the pressure ring 51, under the pressure of the filling bottle 9, drives the sliding frame 6 to compress the spring 8, so that the pressure ring 51 can be tightly closed at the bottle mouth of the filling bottle 9. At the same time, the nozzle of the filling nozzle 4 extends into the filling bottle 9 to complete the filling. After filling, the vacuum component is used to remove the residual filling material at the nozzle of the filling nozzle 4 to prevent the filling nozzle 4 from dripping.

[0023] like Figure 3 and Figure 5 As shown, the vacuum component includes a vacuum tube 12, a vacuum chamber 13, and a vacuum pump 14. The vacuum chamber 13 and the vacuum pump 14 are fixedly mounted on the mounting plate 102. The vacuum chamber 13 and the vacuum pump 14 are connected. The vacuum pump 14 is connected to the nozzle of the filling nozzle 4 through the vacuum tube 12. The vacuum pump 14 is used to generate negative pressure at the nozzle of the filling nozzle 4 so that the remaining filling material after filling on the nozzle of the filling nozzle 4 can be drawn into the vacuum chamber 13 for recovery and temporary storage.

[0024] like Figure 4 As shown, a rubber ring 5 is provided on the bottom surface of the pressure ring 51. Both the pressure ring 51 and the rubber ring 5 have openings in the middle for the nozzle of the filling head 4 to pass through. The rubber ring 5 is used to improve the sealing performance of the pressure ring 51 on the filling bottle 9, and to ensure that there is no leakage at the connection between the filling bottle 9 and the filling head 4.

[0025] like Figure 2 and Figure 3 As shown, a belt conveyor 42 is mounted on the support frame 2 inside the housing 1. The two side walls of the housing 1 are provided with inlet and outlet ports adapted to the belt conveyor 42. The belt conveyor 42 is used to connect and transport the bottles, so that the bottles can be automatically transported to the filling nozzle 4 for filling operation.

[0026] like Figure 3 As shown, an electric push rod 2 is fixedly installed on the support frame 2. A positioning plate 11 is fixedly connected to the piston rod of the electric push rod 2. The top end of the positioning plate 11 extends to the bottom of the filling nozzle 4. The top end of the positioning plate 11 is a "Y" shaped plate. The electric push rod 2 approaches the filling bottle 9 on the belt conveyor 42 through the positioning plate 11, so that the "Y" shaped plate at the end of the positioning plate 11 limits and pushes the filling bottle 9, so that the filling bottle 9 conveyed on the belt conveyor 42 can be accurately limited and positioned by the positioning plate 11 at the filling position of the filling nozzle 4 after it stops.

[0027] like Figure 3 and Figure 5 As shown, a discharge pipe 15 is connected to the lower side of the vacuum chamber 13. A sealing cap 16 is provided at the outlet end of the discharge pipe 15. By rotating the sealing cap 16 at the outlet end of the discharge pipe 15, the canned material recovered in the vacuum chamber 13 can be discharged for recycling and other processing operations.

[0028] When using this filling machine, the bottles to be filled are fed in through the inlet / outlet on the side wall of the machine housing 1 by the belt conveyor 42 and accurately transported to the work position directly below the filling nozzle 4. At this time, the electric push rod 10 on the support frame 2 is activated, and the electric push rod 10 drives the "Y"-shaped positioning plate 11 on the piston rod to move forward, gently and steadily pushing and limiting the bottle to ensure that its mouth is accurately aligned with the filling nozzle 4 above. After the filling process begins, the electric push rod 3 on the support frame 2 is activated, and the electric push rod 3 drives the piston rod to move downward, driving the mounting frame 32 and the bottle fixed on it. As the nozzle 4 is pressed down, the rubber ring 5 on the bottom pressure ring 51 of the connecting rods 61 on both sides of the nozzle 4 first contacts the bottle mouth. As the electric push rod 3 continues to press down, the bottle mouth generates an upward reaction force on the pressure ring 51, forcing the pressure ring 51 to drive the sliding frame 6 connected to it to slide upward along the slide groove 7 of the nozzle 4 housing. At the same time, the spring 8 sleeved on the connecting rod 61 is compressed. This action makes the rubber ring 5 on the pressure ring 51 tightly cover the bottle mouth, forming a reliable seal. Meanwhile, the nozzle of the nozzle 4 overcomes the resistance of the spring 8 and passes through the opening in the middle of the pressure ring 51 and the rubber ring 5. The nozzle 4 smoothly extends into the bottle to a preset depth. After the filling nozzle 4 and the filling bottle 9 are sealed and connected, the filling material in the storage bin 41 flows into the filling nozzle 4 through the pipe and is precisely injected into the bottle from the nozzle. After filling is completed, the vacuum component set on the mounting plate 102 is activated, and the vacuum pump 14 works to form a negative pressure in the vacuum chamber 13. This negative pressure is transmitted to the nozzle tip of the filling nozzle 4 through the vacuum tube 12. The powerful suction instantly sucks away the remaining liquid droplets of filling material adhering to the inner wall of the nozzle and the outlet, and collects them back into the vacuum chamber 13 for temporary storage. This negative pressure suction process can effectively... Eliminating nozzle residue fundamentally prevents material leakage when the nozzle is lifted. After vacuum suction is completed, the electric push rod 3 drives the mounting frame 32 and the filling nozzle 4 to rise and reset smoothly. Under the restoring force of the spring 8, the sliding frame 6 and the pressure ring 51 also move down and disengage from the bottle mouth. At the same time, the positioning plate 11 moves backward under the drive of the electric push rod 10, releasing the limit on the filling bottle 9. The filled bottle is then sent out of the machine box 1 by the belt conveyor 42. Finally, the material recovered in the vacuum chamber 13 can be periodically discharged and treated through the sealing cover 16 of its lower discharge pipe 15.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
