Easy-to-tear knife and ironing block integrated rear transverse sealing ironing block mechanism and transverse sealing device

Abstract

The invention discloses an easy-to-tear knife and ironing block integrated rear transverse sealing ironing block mechanism and a transverse sealing device. The mechanism comprises a rear ironing block, a spring assembly, an easy-to-tear knife, a rear ironing block base and a rear transverse sealing machine frame plate, a knife head groove through hole is formed in the position, penetrating throughthe front surface and the rear surface of the rear ironing block, above a spring threaded hole, the easy-to-tear knife is detachably fixed to the upper surface of the rear ironing block base in the machining feeding direction, and a knife tooth head of the easy-to-tear knife is aligned with the knife head groove through hole; the rear ironing block base is sleeved with the spring assembly in themachining feeding direction, the front end screw head of the spring assembly is connected to the spring threaded hole, so that the rear ironing block moves front and back relative to the ironing blockbase along with the compression of the spring assembly during machining pressing. According to the rear transverse sealing mechanism, the easy-to-tear knife and the ironing block are integrally arranged, the easy-to-tear knife does not need power, the easy-to-tear knife can be pushed by means of power for machining transverse sealing pressing, the mechanism ensures that the position of the easy-to-tear opening is always consistent with the sealing position and the machining accuracy is ensured, procedures and parts are reduced, and the cost is reduced.

Description

technical field [0001] The invention relates to packaging technology, in particular to an integrated rear horizontal sealing ironing block mechanism and horizontal sealing device of an easy-tearing knife and ironing block. Background technique [0002] At present, the multi-column filling and packaging machine for carton packs usually cuts an easy-tear opening at the seal, so that the carton packs can be torn off smoothly. There are usually two methods in the prior art: first, the easy-tear openings are divided into horizontal-seal easy-tear openings and vertical-seal easy-tear openings. These two easy-tear openings are cut at different stations, and each tear opening has an independent Driven, but due to different work stations cutting out one after another, the position of the easy-to-tear gap is deviated. The second type is to cut out the easy-tear openings of the horizontal seal and the vertical seal at the same time. At the station below the horizontal seal, the positi...

Problems solved by technology

There are usually two methods in the prior art: first, the easy-tear openings are divided into horizontal-seal easy-tear openings and vertical-seal easy-tear openings. These two easy-tear openings are cut at different stations, and each tear opening has an independent Driven, but due to different work stations cutting out one after another, the position of the easy-to-tear gap is deviated

The second type is to cut out the easy-tear openings of the horizontal seal and the vertical seal at the same time. At the station below the horizontal seal, the position of the cut-out will deviate from the relative position of the horizontal seal. This is mainly affected by the length of the bag, the mechanical position of the cutter, and the roll film. caused by factors such as tension

[0003] Therefore, the existing two methods cannot ensure that the theoretical relative positions of the easy-tear opening and the horizontal seal are consistent, and position deviation will always occur, making it difficult to guarantee the stability of quality
