Problems solved by technology
[0002] In order to connect the bottle and the cap stably, the connection method of thread is usually used. The existing bottle thread processing device generally requires the cooperation of multiple people, the structure is relatively complicated, and the processing efficiency is low, and the processing device can only be used for processing specific If you need to process bottle mouths with different wall thicknesses, you need to replace a large number of accessories, which is time-consuming and laborious, and it is impossible to realize automatic processing

Embodiment Construction
[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.
[0029] Such as Figure 1 to Figure 8 As shown, a screw forming structure includes a screw main body 1 and a reducing sleeve 2 arranged on the screw main body 1, and the screw main body 1 is movably provided with an inner diameter capable of aligning the bottle mouth. The internal screw cone 3 and the external screw cone 4 are respectively extruded with the outer diameter. The screw body 1 and the reducing sleeve 2 are provided between the bottle body 10 to drive the screw main body 1 in the variable diameter. When doing axial movement in the sleeve 2, the distance d between the centers of the internal screw cone 3 and the external screw cone 4 can be shortened, thereby clamping the adjusting mechanism 5 of the bottle mouth. When the bottle mouth is put into the main body of t...

The invention discloses a screw forming structure. The screw forming structure comprises a screw device main body and a reducing sleeve arranged on the screw device main body; an inner thread wheel and an outer thread wheel which can respectively extrude and mold the inner diameter and outer diameter of a bottle opening are movably arranged on the screw device main body; and an adjusting mechanismcapable of shortening the circle center distance d between the inner thread wheel and the outer thread wheel to clamp the bottle opening when a bottle body drives the thread device main body to do axial movement in the reducing sleeve is arranged between the thread device main body and the reducing sleeve. When the bottle opening is placed into the screw device main body, the screw device main body can be pushed to move in the axial direction along the reducing sleeve, and meanwhile, an adjusting structure drives a first connecting rod and a second connecting rod to approach each other, so that the circle center distance between the inner thread wheel and the outer thread wheel can be decreased, and the inner thread wheel and the outer thread wheel can extrude the bottle opening; and dueto the fact that the bottle body is fixed and the whole device is in a rotating state during operation, the inner thread wheel and the outer thread wheel making contact with the bottle opening can rotate synchronously, and the inner diameter and the outer diameter of the bottle opening are machined and formed at the same time.
Description
【Technical field】 [0001] The invention relates to a screw opening forming structure. 【Background technique】 [0002] In order to connect the bottle and the cap stably, the connection method of thread is usually used. The existing bottle thread processing device generally requires the cooperation of multiple people, the structure is relatively complicated, and the processing efficiency is low, and the processing device can only be used for processing specific If it is necessary to process bottle mouths with different wall thicknesses, a large number of accessories need to be replaced, which is time-consuming and laborious, and automatic processing cannot be realized. [0003] The present invention is produced based on the above problems. 【Content of invention】 [0004] The purpose of the present invention is to address the deficiencies in the prior art, and propose a screw mouth forming structure. When the bottle mouth is put into the main body of the screwdriver, the inne...
