Intermediate packaging machine compression device for disposable absorbent articles

Abstract

The invention discloses an intermediate packaging machine compression device for disposable absorbent articles. The intermediate packaging machine compression device comprises a compression support, as well as a compression plate mechanism and a compression translation mechanism which are installed on the support, wherein the compression support comprises a frame formed by a cross beam and vertical columns, a panel support bar, and a panel fixedly connected above the support bar, and slide rails are arranged on the panel support bar; the compression plate mechanism comprises a left compression mechanism and a right compression mechanism which are symmetrically arranged at the left side and the right side of the panel, the single-side compression plate mechanism comprises a compression plate, a compression bottom plate and a compression support plate which are sequentially connected from the inside to the outside, a product contact surface of the compression plate is an inner concave-arc surface, air channels and uniformly-distributed air vents are arranged in the compression plate, an air source inlet is arranged in the compression bottom plate, and the bottom of the compression support plate is slidably connected with the slide rails; and the compression translation mechanism comprises a ball screw, a screw synchronous belt wheel, a synchronous belt, a motor synchronous belt wheel and a servo motor. The intermediate packaging machine compression device disclosed by the invention is capable of remarkably enhancing a compression force and compression stability, has no phenomenon of two-side sheet leakage, achieves smooth pushing, and has the advantages of being good in compression effect and fast in processing speed.

Description

technical field [0001] The invention relates to tundish machine equipment on a product production line, in particular to a tundish machine compression device on a disposable absorbent product production line. Background technique [0002] At present, the working process of the tucking machine equipment for disposable absorbent products (such as diapers, sanitary napkins, toilet paper, etc.) is as follows: the products that are continuously conveyed on the production line are stacked by the stacker mechanism and pushed out, sorted and arranged, and compacted by the compression device Afterwards, they are grouped and pushed into the packaging bag by the pushing device. [0003] Most of the compaction and conveying mechanisms of the tundish machine in the prior art adopt a moving compaction method: the utility model with the application number 200920192886.9 discloses a diaper packaging machine, which adopts a trapezoidal channel opening, and the diaper is pushed in at the wide...

Problems solved by technology

[0003] Most of the compaction and conveying mechanisms of the tundish machine in the prior art adopt a moving compaction method: the utility model with the application number 200920192886.9 discloses a diaper packaging machine, which adopts a trapezoidal channel opening, and the diaper is pushed in at the wider entrance of the trapezoidal channel, and the The compaction during the pushing process with a single pusher may easily cause the product to be uneven after compression, the product will be squeezed, deformed, scratched, or the diaper will deviate from the entrance of the channel and get stuck when pushing, and cannot be conveyed at high speed; the invention patent application 201510273284.6 discloses a A fully automatic diaper packaging production line, the pre-compression device includes left and right compression mechanisms installed on the compression bracket, the left and right compression mechanisms include a compression translation mechanism, an upper push block and a lower push block, and an upper push block and a lower push block They are respectively driven by independent compression and translation mechanisms, so it can prevent the diapers from being stuck in the channel due to deviation from the position, and improve the smoothness of production; the invention patent of application number 201210151068.0 discloses a tundish machine, which adopts conveyor belt flow operation and is on the feeding line The left and right pressing plates and the pressing plate driving cylinder are set up, wherein the cylinder drives the pressing plate to move left and right, and some of them are conveyed by belts on the left and right sides to realize product compaction while conveying the product. The compaction is stable and does not rebound, and the working noise is small, but it can compress products at high speed or When compressing a large number of products at one time, the neat products will be squeezed and scattered, and it needs to be stopped for cleaning, which affects the work efficiency

[0004] In addition, the compression mechanism used in the above-mentioned prior art is a planar structure, which has a large contact surface with the product and increased friction, which is particularly prone to the phenomenon of missing pieces at both ends, which greatly affects the packaging efficiency and reduces the stability of the equipment.
