Vacuumizing lid rotating device of hard bottle

A vacuum pumping and bottle body technology, which is applied in the direction of packaging and packaging under vacuum/special atmosphere, can solve the problems that the sealing ring and the bottle body cannot be completely fitted, the production efficiency of the capping machine is low, and the energy consumption is large, so as to eliminate If the pressure is too small, the vacuum chamber is not completely sealed, which prevents the bottle from being damaged by fracturing and shortens the time for vacuuming.

Problems solved by technology

In Chinese patent 200820085421.9, a kind of vacuum bottle packaging equipment is disclosed. Its technical principle is to place glass bottles in a vacuum cover, first vacuumize the vacuum cover, and then screw the cap. There are the following disadvantages: the structure of the fully-sealed vacuum capping machine is complex, and a clamp for clamping the bottle needs to be set on the workbench. The bottle to be capped is clamped by the clamp, and the clamp and the bottle must be covered in a vacuum cover. The capping mechanism is installed in the vacuum cover. Bottles of different specifications require different fixtures and corresponding capping equipment. The scope of use of equipment of the same specification is limited. At the same time, because the inner cavity of the vacuum cover needs to accommodate fixtures, The capping bottle also has a capping device, so the volume of the vacuum cover is large. Before screwing the cap, the inner cavity enclosed by the vacuum cover and the working platform must be evacuated, and the cap can only be screwed when the predetermined vacuum degree is reached. This not only The time of vacuuming is long, which consumes a lot of energy, and the production efficiency of the capping machine is low, and the user cost is high
[0007] Since the sealing device used is a rubber sealing ring with a thicker wall thickness, there is an air expansion chamber clamping mechanism outside the sealing ring. The wall thickness of the sealing ring is relatively thick. When the inflation chamber is inflated, the deformation of the sealing ring after compression is limited. It is difficult to ensure that the sealing ring can form a reliable sealing structure with the outer circle of the hard bottle body. At the same time, the hard bottle The body is generally a glass bottle, and the body of the glass bottle always has a certain degree of out-of-roundness. The body of the glass bottle cannot be completely round, and the sealing ring and the body of the bottle cannot be completely fitted. It is necessary to improve the sealing here. The effect can only increase the inflation pressure of the inflation chamber. If the inflation pressure is too high, the bottle body will be crushed and damaged. If the pressure is too small, not only the sealing performance of the vacuum chamber cannot be guaranteed, but also the bottle body cannot be fixed. Relative to the sealing ring, there will be rotation, the bottle cap is difficult to tighten, and the sealing ring will be worn, which makes it difficult to solve the contradiction between the sealing and clamping of the bottle body and the prevention of bottle body clamping and damage.

Embodiment 1

[0026] Embodiment 1: a kind of hard bottle body vacuum capping device, such as Figure 1 ~ Figure 2As shown, it includes a capping shaft 1, a capping head 2, a vacuum cover 3, a main shaft sealing ring 4, an inflatable clamping sealing ring 5, a vacuum switching valve 6 and a bearing 7. The vacuum cover 3 includes a vacuum interface 31, a cylinder 32. Air guide port 33, shaft hole 34, bearing hole 35, spindle sealing ring installation hole 36 and inflatable sealing ring installation groove 37, vacuum interface 31 is set above the inflatable clamping sealing ring 5, and is connected with the inside of the vacuum cover 3 The cavities are connected, the vacuum interface 31 is connected with the vacuum device through the vacuum switch valve 6, the cylinder body 32 is a cup-shaped body with an open lower end, and the shaft hole 34, the bearing hole 35 and the spindle sealing ring installation hole 36 are all set in the cylinder body. 32, the bearing 7 is installed in the bearing ho...

Embodiment 2

[0027] Embodiment 2: The difference from Embodiment 1 is that, as image 3 As shown, the bottle body clamping structure 9 is also included, and the bottle body clamping structure 9 is arranged between the workbench and the vacuum cover 3, and it is composed of a bottle dial 91 and a bottle pressing block 92. Evenly set the bottle pulling grooves to accommodate the bottle body. When the bottle body is transferred from the bottle dial 91 to the station to be capped, the bottle pressing block 92 moves to the direction of the bottle dial 91 to press the bottle body under the action of the driving mechanism. , so that the bottle body to be capped is fixed relative to the vacuum cover 3, and the air-filled clamping sealing ring 5 only realizes sealing and coating on the bottle body, and the sealing pressure can be reduced, so that the clamping and sealing of the bottle body can be realized. , can thoroughly eradicate the defects existing in the prior art.

Abstract

The invention discloses a vacuumizing lid rotating device of a hard bottle. The device comprises a lid rotating shaft, a lid rotating head, a vacuum cover, a main shaft sealing ring and an inflation clamping sealing ring; the lid rotating shaft is mounted on the vacuum cover through the main shaft sealing ring; the lid rotating head is fixedly mounted at the lower end of the lid rotating shaft, and is arranged in an inner cavity of the vacuum cover; the inflation clamping sealing ring is peripherally arranged on the side wall of the lower section of the inner cavity of the vacuum cover; the lid rotating head is positioned above the inflation clamping sealing ring; the inflation clamping sealing ring is communicated with a pressure gas source through a pressure gas access control device; and a vacuumizing joint is formed in the vacuum cover above the inflation clamping sealing ring, and is connected with the inner cavity of the vacuum cover and a vacuumizing device. The vacuumizing lid rotating device greatly improves the tightness of the inner cavity of the vacuum cover, largely reduces the vacuumizing energy consumption, shortens the vacuumizing time, is high in production efficiency, is more reliable in clamping of the bottle, and prevents the conditions of fracturing damage of the bottle caused by overhigh inflation pressure and incomplete sealing of a vacuum chamber caused by overlow pressure.
