Description

Technical Field

[0001] The utility model relates to the field of plastic bottle edge trimming, in particular to a plastic bottle edge trimming machine. Background Art

[0002] Blow-fill-seal three-in-one aseptic filling technology refers to bottle blowing-filling-sealing. Blow-fill-seal is an advanced aseptic processing technology. During the whole process, plastic containers are extruded from polymer particles into molds, and then filling and sealing are completed in a set of continuous processes. It is different from the traditional aseptic operation process in which container molding, preparation, sterilization, filling and sealing are completely independent. Compared with traditional aseptic filling, blow-fill-seal is an advanced aseptic filling process because the whole process is automated and does not require many workers to operate during the production process. Therefore, using a reasonably configured blow-fill-seal machine for aseptic filling can achieve a high degree of sterility. When the existing blow-fill-seal equipment is used for production and packaging, there are a lot of waste edges around the formed plastic bottles, which must be removed with the help of special trimming devices during subsequent use.

[0003] The prior art can only perform trimming processing on a single plastic bottle, but cannot perform cutting processing on multiple plastic bottles at the same time. Moreover, when cutting multiple plastic bottles, it is impossible to ensure that the positions of the plastic bottles remain aligned, which makes it easy to damage the plastic bottles during cutting.

DETAILED DESCRIPTION

[0017] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0018] See also Figures 1 to 5 In this embodiment, a plastic bottle trimming machine is provided, including a base 1 and a cutting knife 2. A left seat 11 is arranged on the upper end surface of the base 1. A plurality of pressure sensors 12 are embedded in the right end surface of the left seat 11 from front to back. A plurality of warning lights 13 are embedded in the left end surface of the left seat 11. A top platform 24 is installed on the outer end of the base 1. An adjusting motor 14 is installed on the upper end surface of the top platform 24. An adjusting cam 15 is installed on the output end of the adjusting motor 14. A cutting knife 2 is arranged below the adjusting cam 15. A right cavity is arranged on the right side of the cutting knife 2. A spring rod 16 is installed at the bottom of the right cavity. A first slider is installed on the upper end surface of the spring rod 16. The cutting knife 2 is installed on the left end surface of the first slider through a connecting rod. The front end surface of the top platform 24 A control panel 22 is installed, and the control panel 22 is electrically connected to the warning light 13 and the pressure sensor 12. When working, multiple plastic bottles are placed horizontally on the base 1, and one end of the plastic bottle is close to the right end surface of the left seat 11.
