Description

Technical Field

[0001] The invention relates to the field of fusion sealing machines, and more specifically to a fusion sealing machine for the end of a medium-borosilicate medicinal glass tube. Background Art

[0002] Medium borosilicate glass bottles are just one of the categories of borosilicate glass. Low borosilicate glass also counts, but there are differences between the two. The main difference between the two is that they have a higher content of boron trioxide, higher thermal stability and chemical stability, and a stronger ability to withstand drastic temperature changes. Therefore, the medicine bottles made from them also have certain performance differences; medium borosilicate pharmaceutical glass is one of the most commonly used pharmaceutical filling containers at present, mainly used for filling and processing of liquid drugs to prevent the drug from deteriorating due to contact with the outside air, affecting the efficacy and shelf life of the drug; after filling, the medium borosilicate pharmaceutical glass bottle generally needs to be sealed with a sealing machine to achieve the effect of sealing.

[0003] When the melting and sealing machine for borosilicate medicine glass bottles in the prior art is used, a fire gun is usually used to melt the top of the glass bottle, and then a clamp is used to pull the top of the glass bottle to separate it from the bottle body. Although it can achieve the effect of sealing, this packaging method is prone to glass burrs on the top of the bottle body, resulting in the melting and sealing of the top of the bottle body not being smooth and too abrupt, affecting subsequent packaging and use by medical staff. In addition, the position of the spray gun equipped in the melting and sealing machine in the prior art is basically fixed. If the height of the spray gun needs to be adjusted, multiple parts need to be loosened and tightened, and the operation steps are relatively cumbersome. It is also not convenient to adapt to borosilicate medicine glass bottles of different specifications, which greatly reduces the actual application efficiency. Summary of the invention

[0032] The hose 7 is mainly connected to an external gas supply device, and the combustible gas is transported to the two first spray guns 6 through the hose 7 to heat the glass tube.

[0033] In some embodiments, see Figure 1 and Figure 4 The adjusting component includes a first through groove 4, which is provided on the side wall of the fixed plate 3, and a movable block 5 is movably connected in the first through groove 4.

An air claw 22 is fixedly mounted near the right side of the bottom surface of the support plate 20. A shaping component is arranged near the left side of the bottom surface of the support plate 20. The use of the packaging component can not only achieve the effect of rapid packaging, but also perform secondary heating to assist shaping, effectively ensuring the quality and surface curvature of the glass tube after forming, and reducing the probability of defective products.

[0037] In some embodiments, see Figure 2 and Figure 3 The shaping component includes a second cylinder 24, which is fixedly mounted on the top surface of the support plate 20. The output end of the second cylinder 24 passes through the support plate 20 and is fixedly connected to a cylinder 23. A truncated cone block 25 is arranged in the cylinder 23.

Through the mutual cooperation between the mounting plate 16, the packaging component and the shaping component, when the glass bottle is melted by the first spray gun 6, the top of the glass bottle is immediately pulled out by the air claw 22 to separate it from the bottle body, and the second spray gun 21 is used to heat it again to melt the burrs on the top of the glass bottle, and the shaping mechanism is used to make the top of the glass bottle smoother and of better quality.

[0038] The air gripper 22 can be replaced with other pneumatic components according to actual needs to achieve the best gripping effect.

[0039] In some embodiments, see Figure 1 The guide assembly includes a groove 28, which is opened on the side wall of the support plate 1. An inclined plate 29 is arranged in the groove 28. The top surface of the support plate 1 is threadedly connected with a screw 30, and the screw 30 is threadedly connected to the inclined plate 29. By setting the guide assembly, it can be adjusted according to the size of the bottle body, so that the glass bottle is in an accurate position during transportation.

[0040] Among them, a fixed clamping mechanism can be added on the inner side of the fixed plate 3 to clamp the glass bottle to prevent shaking or deviation during the heating process. This technical solution belongs to the existing mature technology and will not be elaborated in this solution.

[0041] When in use: first adjust the spacing between the inclined plates 29 on both sides according to the specifications of the glass bottles, first loosen the screws 30 to adjust the inclined plates 29 to a suitable position, then tighten the screws 30 to lock them, and then stack the glass bottles that need to be sealed on the conveyor belt 2 in sequence. When the glass bottles are transported to the lower side of the fixed plate 3, the conveyor belt 2 is paused, and the first spray gun 6 is started to spray flames. At the same time, the telescopic rod 15 runs, pushing the rack 13 on one side to move, the rack 13 engages the gear 14 and drives the rack 13 on the other side to move in the opposite direction, and the racks 13 on both sides drive the first spray gun 6 to approach the glass bottles for heating through the adjustment plate 8. After heating, the conveyor belt 2 Move the glass bottle quickly to the bottom of the air claw 22. At this time, the first air cylinder 17 is used to drive the air claw 22 to move downward to grab the edge of the glass bottle. The first air cylinder 17 is quickly reset to break the top of the glass bottle to separate it from the bottle body. Then, the second spray gun 21 is used to heat it again, and the cylinder 23 is driven to rotate by the rotating cylinder 19. At this time, the first cylinder 17 first drives the cylinder 23 to move downward and extend into the top of the glass bottle. Then, the second air cylinder 24 is used to press down the truncated cone block 25, so that the shaping plate 26 shrinks to shape the top of the glass bottle to achieve the purpose of smooth sealing. Repeating the above steps can effectively improve its use efficiency.

[0042] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
