Embodiment Construction

[0011] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0012] Such as Figure 1-2 As shown, the feed packaging exhaust counter-roller of the present invention includes a lower flat roller 1 and an upper pressure roller 2, the surface of the pressure roller 2 is designed with a longitudinal pressure groove 3, and the pressure groove 3 The size is adapted to the size of the spatula.

[0013] The beneficial effect of the exhaust counter-roller for feeding packaging provided by the present invention is that the tongue depressor can be included in the design of the longitudinal groove, and the upper pressure roller will not be in direct contact with the tongue depressor. Destructive pressure will be generated, and at the sa...

Abstract

The invention relates to an exhaust paired roller of a feeding package, which comprises a lower flat roller and an upper pressing roller; a longitudinal pressing groove is arranged on the surface of the pressing roller; and the pressing groove is matched in size with a tongue depressor. The exhaust paired roller of the feeding package provided by the invention has the beneficial effects that: using the design of the longitudinal pressing groove, the tongue depressor can be included in the longitudinal pressing groove and the upper pressing roller may not directly contact the tongue depressor, so that the destructive pressure may not be formed, and meanwhile, the pressing roller out of the pressing groove can work with the flat roller to exhaust air in a package bag so as to ensure the flatness of the package bag to the greatest extent.

Description

technical field [0001] The invention relates to a pair of exhausting rollers for feeding and packaging, and belongs to the technical field of production equipment for commonly used spatulas for medical devices. Background technique [0002] At present, tongue depressors only use more traditional production equipment. In this technical field, after searching, it was found that domestic technical websites could not find the newly developed technical information, including the official website of the State Intellectual Property Office, China Machinery Network, etc. Therefore, it can be generally believed that at present, at least domestic equipment manufacturers have invested less in the research and development of tongue depressors or simply engaged in the production of traditional equipment, but have not put forward good solutions for the technical problems existing in traditional equipment. solution. After many years of design and production experience of our technical sta...
