Description

Technical Field

[0001] This utility model relates to the field of air exchange devices, specifically to an air exchange device for a blister packaging machine. Background Technology

[0002] Blister packaging machines use heated and softened rigid plastic sheets to be blown into blister packs by compressed air under pressure. The contents of the blister packs are then filled and heat-bonded with a special aluminum-plastic composite. This method is suitable for packaging various sizes of sugar-coated tablets, uncoated tablets, capsules, and softgels, as well as small hardware, electronic components, medical devices, and food products with similar shapes. To prevent the air inside the blister pack from affecting the contents, air replacement devices have been developed to replace the air with nitrogen, which is beneficial for product preservation. For example, Chinese patent 202311174591.X discloses an air replacement device and blister packaging mechanism. It has the following advantages: it can replace the air inside the blister pack, improving the preservation effect of the contents.

[0003] However, the patent still has the following drawbacks: because the position of the purge tube is fixed, there are limitations in position adjustment, which may lead to inaccurate alignment between the purge tube and the bubble cap, affecting the replacement effect. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide an air replacement device for a blister packaging machine that enables multi-degree-of-freedom adjustment of the nozzle in the up-down, left-right, and front-back directions, thereby ensuring that the nozzle can maintain the optimal alignment position with the blister before heat sealing, significantly improving nitrogen replacement efficiency and packaging quality.

[0005] According to the technical solution provided by the present utility model embodiment, an air replacement device for a blister packaging machine includes a nozzle, an adjusting plate fixedly connected to the side of the nozzle, an elongated slot on the outer periphery of the nozzle, and an elongated opening on the surface of the adjusting plate; a transition frame, which is installed above the adjusting plate by a first screw and a first nut, the end of the first screw passing through the elongated opening, the transition frame having a U-shaped structure, an arc-shaped opening on the side of the transition frame, and the first nut screwed onto the outside of the first screw;

[0006] The bracket is installed above the transition frame by a second screw and a second nut. A cover plate is fixedly installed at the end of the bracket. The bracket has an inverted T-shaped structure. The end of the second screw at the top passes through the arc-shaped opening, and the second nut is screwed on the outside of the second screw.

[0007] A sliding seat is slidably mounted on the outside of the bracket. A third nut is fixedly mounted on the outside of the sliding seat. A third screw is screwed into the inside of the third nut. The end of the third screw abuts against the outer wall of the bracket. The sliding seat is slidably engaged with the bracket.

[0008] Mounting plate, which is fixedly connected to the sliding seat, with reinforcing ribs fixedly connected between the mounting plate and the sliding seat, and a fourth screw passing through the mounting plate; connecting ear, which is fixedly connected to the lower part of the bracket, and washers are provided between the first nut and the adjusting plate, between the second nut and the connecting ear, and between the fourth screw and the mounting plate.

[0009] In summary, the beneficial effects of this utility model are as follows: through the cooperation of components such as the nozzle, bracket, transition frame, and sliding seat, the nozzle can be adjusted in multiple degrees of freedom in the up-down, left-right, and front-back directions. Specifically, left-right adjustment is achieved by the cooperation of the elongated opening on the adjustment plate with the first screw, up-down adjustment is achieved by the sliding cooperation of the sliding seat and the bracket, and front-back rotation adjustment is achieved by the cooperation of the arc-shaped opening on the transition frame with the second screw. This ensures that the nozzle can maintain the optimal alignment position with the blister pack before heat sealing, significantly improving nitrogen replacement efficiency and packaging quality.

[0019] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An air displacement device for a blister packaging machine includes a nozzle 1, with an adjusting plate 6 fixedly connected to the side of the nozzle 1; a transition frame 3, which is mounted above the adjusting plate 6 by a first screw 7 and a first nut 8; a bracket 2, which is mounted above the transition frame 3 by a second screw 9 and a second nut 10, with a cover plate 5 fixedly mounted at the end of the bracket 2; a sliding seat 4, which is slidably mounted on the outside of the bracket 2, with a third nut 11 fixedly mounted on the outside of the sliding seat 4, and a third screw 12 screwed into the inside of the third nut 11; a mounting plate 13, which is fixedly connected to the sliding seat 4; and a connecting ear 14, which is fixedly connected below the bracket 2.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the nozzle 1 has a long slot on its outer periphery for air outlet, and the bracket 2 has an inverted T-shaped structure. The surface of the adjusting plate 6 has a long opening, and the end of the first screw 7 passes through the long opening to cooperate with the first screw 7 to adjust the nozzle 1 left and right.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the transition frame 3 has a U-shaped structure, and a reinforcing rib is fixedly connected between the mounting plate 13 and the sliding seat 4, which can improve the firmness of the connection between the mounting plate 13 and the sliding seat 4. The side of the transition frame 3 is provided with an arc-shaped opening, and the end of the second screw 9 passes through the arc-shaped opening to cooperate with the second screw 9 to realize the front and rear rotation adjustment of the nozzle 1.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the first nut 8 is screwed onto the outside of the first screw 7, and the second nut 10 is screwed onto the outside of the second screw 9. The end of the third screw 12 abuts against the outer wall of the bracket 2, and a fourth screw passes through the mounting plate 13. The sliding seat 4 slides with the bracket 2 to achieve vertical adjustment of the nozzle 1. Washers are provided between the first nut 8 and the adjusting plate 6, between the second nut 10 and the connecting lug 14, and between the fourth screw and the mounting plate 13 to prevent the first nut 8, the second nut 10, and the fourth screw from loosening.

[0023] In use: First, use the fourth screw to install the mounting plate 13 near the blister packaging machine. Loosen the third screw 12, and slide the bracket 2 up and down through the sliding engagement of the sliding seat 4 and the bracket 2. Tighten the third screw 12 so that the end of the third screw 12 abuts against the outer wall of the bracket 2 to fix the bracket 2. Then loosen the first nut 8, slide the adjusting plate 6 left and right through the elongated opening on the adjusting plate 6, and tighten the first nut 8 to fix the adjusting plate 6. Then loosen the second nut 10, and through the transition... The arc-shaped opening on the frame 3 allows for the rotation of the transition frame 3 and the tightening of the second nut 10, which can fix the transition frame 3. This enables the nozzle 1 to rotate freely in the up-down, left-right, and front-back directions, ensuring that the nozzle 1 maintains the optimal alignment with the blister pack before heat sealing. This significantly improves the nitrogen replacement efficiency and packaging quality. Subsequently, nitrogen enters the nozzle 1 through the pressure regulating valve, throttle valve, and flow meter. The nitrogen is then sprayed into the blister pack before heat sealing through the long slot of the nozzle 1, which can replace the air inside the blister pack and improve the preservation effect of the items.
