Variable pitch feeding conveying mechanism

Abstract

The invention discloses a variable pitch feeding conveying mechanism, which comprises a rack, a chain wheel group, a plurality of conveying rods and a regulation device, wherein the chain wheel group and the regulation device are arranged in the rack respectively; the conveying rods are arranged on the chain wheel group, are driven by the chain wheel group to cyclically move, and are in contact with the regulation device. The variable pitch feeding conveying mechanism is easy to operate, and can work reliably, material, labor and time cost are reduced, and production efficiency can be improved.

Description

technical field [0001] The invention relates to a technology in the field of pillow packaging machinery, in particular to a variable-pitch feeding and conveying mechanism. Background technique [0002] At present, pillow packaging machines have been widely used in various industries such as food and daily necessities, and the product specifications are becoming more and more abundant, and the packaging speed is getting faster and faster. The feeding conveying mechanism of the current pillow packaging machine is to send the packaged objects into the pillow packaging machine bag through the fixed-pitch feeding push rod set on the feeding chain, and then complete the sealing and cutting packaging through the action of the end sealing knife. In order to ensure that the linear speed of the packaged goods matches that of the end-sealing knife when it reaches the end-sealing knife, the distance between the push rod pitch on the feed chain of the pillow packaging machine and the end...

Problems solved by technology

[0003] However, the feed conveying mechanism of the existing pillow packaging machine uses a single feed push rod with a fixed pitch. When packaging products of different specifications, the length of the chain link needs to be doubled, which not only increases equipment costs and maintenance It also increases the time for manual adjustment of equipment, reduces production efficiency, and affects the quality of packaging

[0004] After searching the prior art, it was found that the Chinese Patent Document No. CNCN203975760U was published (announced) on 2014.12.03, which disclosed a conveyor chain for a food packaging machine, aiming to provide a conveyor chain with adjustable block spacing. A fixed seat is set on the top, and a detachable telescopic structure is set at the bottom of the block, so that the block and the fixed seat can be disassembled freely, and the adjustment purpose of the distance between adjacent blocks is realized, but the technical block must be adjusted manually one by one. cumbersome
