Shear-fork type distance adjusting device

Abstract

The invention discloses a shear-fork type distance adjusting device. The device comprises a rack, a lead screw, a guide rail, a shear fork mechanism, first sliding blocks and second sliding blocks. The two ends of the lead screw are provided with threads in opposite rotating directions. The lead screw is fixed to the rack through a mounted bearing. The guide rail is fixed to the rack through a fixing block. The shear fork mechanism comprises a first connecting rod and a second connecting rod with the same length. The end of the first connecting rod and the end of the second connecting rod arehinged through a first plug pin. The middle of the first connecting rod and the middle of the second connecting rod are hinged through a second plug pin. The first sliding blocks and the second sliding blocks sleeve the guide rail in a spaced mode. The two ends of the lead screw are sleeved with nuts. The nuts are connected with the first sliding blocks at the two ends of the guide rail through connecting plates. The first sliding blocks on the guide rail are connected with the second plug pin. The second sliding blocks are provided with plug pin grooves. First plug pins are inserted into theplug pin grooves. The device is simple in structure, the first sliding blocks at the two ends of the guide rail can move relative to the guide rail. The shear fork mechanism drive the other sliding blocks to perform motion of the same increment or decrement on the guide rail, and the equidistant adjustment of the width of a bottle conveying channel is achieved.

Description

technical field [0001] The invention relates to a space adjustment device between a bottle partition plate and a bottle conveying channel of a plastic bottle packaging machine, in particular to a scissor-type space adjustment device. Background technique [0002] Packaging machines are widely used in the production of products such as food and beverages. In the production process, filling and packaging form a complete production line. Under the conveying of the conveyor belt, it enters the bottle conveying channel of the packaging machine under the action of the bottle partition plate of the packaging machine for packaging. In order to speed up the efficiency, the bottle divider and the bottle conveying lane are often set up as several parallel bottle conveying lanes for packaging. At the same time, in order to meet the needs of packaging different types of bottles, it is often necessary to separate the bottle dividers and conveying lanes. to adjust the spacing. Therefore,...

Problems solved by technology

Therefore, it is necessary to adjust the parallel bottle separators and bottle conveying channels to have the same spacing, and the distance increment or decrement between each bottle separator and bottle conveying channels needs to be equal. The existing ones can only be manually adjusted in turn. The distance between bottle separators, bottle conveying channels, or other more complex adjustment devices, each adjustment takes a long time and is inefficient, reducing production efficiency
