Description

Technical Field

[0001] This utility model relates to the field of potting device technology, specifically a multi-needle potting nitrogen protection system. Background Technology

[0002] Filling and sealing machines are widely used in the food and pharmaceutical packaging machinery industry. Their main processes are: bottle feeding, pre-nitrogen filling, liquid filling, post-nitrogen filling, string sealing, and bottle discharge, all carried out sequentially along the bottle conveying track.

[0003] Currently, most product processes require a residual oxygen content of 2-3% (or even lower), so the pre- and post-nitrogen filling processes play an extremely important role in the entire filling process.

[0004] When using multi-needle filling operations, different filling needles of different specifications are required for filling different products. It takes a lot of time for the staff to change them one by one. Moreover, the adjacent filling needles are close together, which can easily cause unnecessary collisions between them, increasing the difficulty of operation and reducing the efficiency of filling nitrogen.

[0022] Please see Figures 1 to 5 A multi-needle potting nitrogen protection system includes a support plate 2 fixedly installed on the top of a bracket 1, a support column 14 fixedly installed below one end of the support plate 2, a sliding sleeve 15 slidably sleeved on the outer side of the support column 14, a movable block 4 fixedly installed above the sliding sleeve 15, a parallel rod 19 movably installed below the movable block 4, a plurality of potting needles 11 threaded on one side of the parallel rod 19, a fixed sleeve 5 fixedly installed at the right end of the movable block 4, and a movable sleeve 6 movably installed at the left side of the movable block 4.

[0023] In this embodiment: by setting up a movable sleeve 6, a potting needle 11, a parallel rod 19, and a sliding sleeve 15, and by distributing the potting needle 11 in a straight array on one side of the parallel rod 19, a parallel potting method is adopted, which can perform multiple potting operations at one time, thereby improving the potting speed. By connecting the movable sleeve 6 to the parallel rod 19 and the movable block 4, different specifications of potting needles 11 can be replaced in a short time to meet the potting needs of different products.

[0024] As a technical optimization of this utility model, an electric telescopic rod 3 is fixedly installed on the upper part of the support plate 2, and the output end of the electric telescopic rod 3 is fixedly installed on the lower part of the sliding sleeve 15.

[0025] In this embodiment: by setting an electric telescopic rod 3, it is convenient to drive the sliding sleeve 15 to slide along the support column 14, so that the sliding sleeve 15 can drive the movable block 4 to move, thereby driving the potting needle 11 to perform moving potting operation.

[0026] As a technical optimization of this utility model, a first magnet 8 is nested inside the movable sleeve 6, a pull handle 7 is fixedly installed on one side of the movable sleeve 6, a second magnet 16 that is magnetically attracted to the first magnet 8 is nested at the left end of the movable block 4, and the movable sleeve 6 and the movable block 4 are magnetically connected; an installation groove 17 is provided below the movable block 4, and a plurality of ventilation channels 18 are provided on the surface of the installation groove 17, and the movable block 4 is movably connected to the fixed sleeve 5.

[0027] In this embodiment: by setting the first magnet 8 and the second magnet 16, when the movable sleeve 6 is fitted onto the left end of the movable block 4, the first magnet 8 and the second magnet 16 can be magnetically attracted, so that the movable sleeve 6 can attract and fix the parallel rod 19 installed inside the mounting groove 17 on the left end of the movable block 4. The parallel rod 19 can be installed inside the mounting groove 17 by the movable sleeve 6 and the fixed sleeve 5, which facilitates the ventilation and filling operation.

[0028] As a technical optimization of this utility model, multiple air supply hoses 12 are fixedly connected to the top of the movable block 4, and a flow regulating valve 13 is fixedly installed on the outside of the air supply hoses 12. The air supply hoses 12 are connected to the air passage 18.

[0029] In this embodiment: by setting the flow regulating valve 13, the flow rate of nitrogen delivered in the gas delivery hose 12 can be adjusted, so that when multiple filling needles 11 deliver nitrogen, the nitrogen can be evenly distributed in the filling area, effectively isolating oxygen and improving the filling quality.

[0030] As a technical optimization of this utility model, a fixed block 9 is fixedly installed above the movable block 4, and a square rod 10 is slidably sleeved on the inner side of the fixed block 9. One end of the square rod 10 is fixedly installed with the movable sleeve 6. A sealing sheet 20 is fixedly installed on one side of the parallel rod 19, and the filling needle 11 is in sealing contact with the ventilation channel 18 through the sealing sheet 20.

[0031] In this embodiment: the square rod 10 can slide along the fixed block 9, ensuring that when the movable sleeve 6 is disengaged from the left end of the movable block 4, the movable sleeve 6 is flush with the movable block 4, making it easy for the movable sleeve 6 to fit onto the left end of the movable block 4 to install the parallel rod 19 in the mounting groove 17 for potting. The sealing plate 20 can seal the parallel rod 19 with the ventilation channel 18 to ensure the normal delivery of nitrogen and avoid nitrogen leakage and loss.

[0032] Working principle: The movable sleeve 6 is installed on the inner side of the movable block 4 through the connection of the parallel rod 19, so that the sealing plate 20 is connected and sealed with the vent 18. This facilitates the delivery of nitrogen through the gas delivery hose 12 and the vent 18 to the filling needle 11 for filling. By distributing the filling needles 11 in a straight array on one side of the parallel rod 19, multiple filling operations can be performed at once using a parallel filling method, which improves the filling speed. When the filling needles 11 spray nitrogen for filling, the flow rate of nitrogen delivered in the gas delivery hose 12 is adjusted by the flow regulating valve 13. This design ensures that nitrogen is evenly distributed in the filling area when multiple filling needles 11 are delivering nitrogen, effectively isolating oxygen and improving filling quality. When the filling needles 11 need to be replaced, the movable sleeve 6 and the square rod 10 are moved along the fixed block 9, allowing the parallel rod 19 to be removed from the mounting slot 17. This facilitates batch replacement of the filling needles 11 installed on the parallel rod 19. By using the movable sleeve 6 to connect and install the parallel rod 19, different specifications of filling needles 11 can be replaced in a short time to meet the filling needs of different products and improve production efficiency.
