Cover pressing head of cover pressing machine for inner plugging cover

Abstract

The invention discloses a cover pressing head of a cover pressing machine for an inner plugging cover, which is arranged at the lower end of a lifting arm and comprises a guide sleeve fixed on a rotating shaft, wherein a pressing shaft capable of sliding relative to the guide sleeve is sheathed in the guide sleeve; the lower end of the pressing shaft is provided with a cover pressing body; a cover taking port of the cover pressing body is interference fit with a part of the inner plugging cover grasped by the cover pressing body; the inner diameter at an inlet of the cover taking port is less than the outer diameter of a supporting ring of the inner plugging cover. In the cover pressing head, since the cover pressing body is provided with the cover taking port which is interference fit with the part of the inner plugging cover extending out of a bottleneck, after the cover pressing head moves downwards at the cover taking station and presses the part of the inner plugging cover grasped by the cover pressing body into the cover taking port, the supporting ring of the inner plugging cover abuts against the lower end surface of the cover pressing body, and the part of the inner plugging cover grasped by the cover pressing body is stably clamped in the cover taking port of the cover pressing body due to interference fit with the inner wall of the cover taking port, so that the inner plugging cover can not fall by self due to instable clamping after cover taking, and further the smoothness of the cover pressing work is ensured.

Description

technical field [0001] The invention relates to a capping head, in particular to a capping head of an inner plug capping machine. Background technique [0002] In the production line of bottled soy sauce or other bottled products that need to be press-fitted with inner plug caps, after the filling machine fills the predetermined amount of material into the bottle, it is necessary to press the inner plug cap first, and then the outer cap of the bottle capping treatment. In order to improve production efficiency, the existing technology uses a capping machine to cap the outer cap of the bottle; when working, the capping head of the capping machine rotates along the track of the cam along with the lifting arm and moves up and down, and goes down at the cap removal station. Put the bottle cap with the bottle mouth facing down into the cap-taking port of the bottle gland body, and clamp the bottle cap with the pressure ball installed on the side wall of the cap-glanding port (th...

AI Technical Summary

Problems solved by technology

[0003] But the capping machine of prior art can only carry out accurate and effective capping processing to the outer cap of the bottle, but is difficult to carry out accurate and effective capping processing on the inner plug cap. The part to grab is short and its side wall is thin. When the capping head of the capping machine in the prior art is removing the cap, its pressure ball lock clamping device cannot clamp the part of the inner plug protruding from the bottle cap firmly. In the cover opening, therefore, the inner plug cap is easy to drop from the gland body, so that the pressing work of the inner plug cap in the next step cannot be carried out smoothly; The matching clearance of the inner diameter is small, and the side wall of the inner plug cap is thinner, so it requires a higher centering accuracy between the inner plug cap and the bottle mouth, but the inner plug capping is performed by using a bottle capping machine. When the gland is working, the centering accuracy between the bottle mouth and the inner plug often cannot meet the accuracy requirements. Therefore, in the process of pressing the inner plug into the bottle mouth, it is easy to cause the inner plug to be crooked or crushed.

For this reason, the existing technology still adopts manual capping work for the inner plug cap, and the efficiency of the manual capping method is low, which affects the production process of the entire bottled product
