Description

Paper pulp feeding device

Technical Field

The invention relates to the technical field of sanitary product manufacturing equipment, in particular to a paper pulp feeding device.

Background

The development of the sanitary product industry is different day by day, the requirement of consumers on the water absorption performance of the absorption core body of the disposable sanitary product is higher and higher, at present, the traditional sanitary product adopts a single-layer absorption core body style, is influenced by various condition factors, the water absorption performance of the single-layer absorption core body is often restricted, in recent years, the defect of the single-layer absorption core body in the water absorption performance is overcome by the double-layer absorption core body, and the sanitary product containing the double-layer absorption core body style is popular among a large number of consumers. As equipment manufacturers, in order to form the double-layer absorbent core structure, two sets of absorbent core forming devices are often designed on the production equipment of the sanitary products, namely two sets of pulp feeding devices, pulp crushing devices and the like are required to be arranged, and the arrangement reasonability of the devices is a problem which is important to be considered in the initial design stage of the equipment manufacturers. The arrangement of two sets of pulp crushing devices is usually one in front and back, so that the second pulp feeding device at the back is positioned right above the first pulp crushing device at the front.

However, in the initial stage of equipment adjustment or in the case of clogging of pulp due to various causes and ordinary maintenance, the pulp crushing apparatus often opens a casing of the crushing apparatus to perform various operations on the crushing apparatus. In addition, because the traditional paper pulp feeding device is of a fixed tray structure, the traditional paper pulp feeding device is very troublesome to disassemble after installation, and a certain height is required to be kept between the front first crushing device and the rear second paper pulp feeding device, and the height is ensured to ensure that the safety door of the housing of the front first crushing device cannot interfere with the rear second paper pulp feeding device when the safety door of the housing of the front first crushing device is opened, so that the height requirement of a factory building is relatively high. However, due to the limitation of the length or height of the plant of the equipment purchaser of the sanitary product, the manufacturer of the equipment often cannot be designed according to the conventional layout, and needs to make an adjustment according to the actual situation of the plant of the equipment purchaser.

The existing equipment structure is that one or more operation flat plates are arranged below two crushing devices, the arrangement of the flat plates is not only used for installing the two crushing devices, but also a pulp receiving electrical operation box, a crushing device operation screen, a polymer feeding device, an alarm lamp and the like are arranged on the flat plates, and in addition, operators can also perform more adjustment, operation and maintenance work on the flat plates. And because the structural design of the fixed tray in the paper pulp feeding device often reduces and hinders the space operated by operators on the platform, so that part of adjustment is difficult to expand in the existing space, the fixed tray for feeding the paper pulp is often disassembled in order to obtain larger adjustment space, thus the operation is troublesome and laborious, a plurality of operators can complete the operation together, and the production efficiency is greatly reduced.

On the other hand, the pulp feed driving device is generally designed to be placed before the crushing device, i.e. the pulp material is passively transported from the pulp roll to the pulp driving device. And the design of the fixed tray structure of the pulp feeding device, in the running process of actual equipment, the whole width of the pulp raw material always makes surface contact with the tray, so that larger friction is often generated, and the defect is more obvious particularly in high-speed running. And fixed tray also can cause the deformation of middle spill because of the tray dead weight very easily, and the design of tray length is limited in the design in advance again, and the design overlength is out of shape seriously and the transport installation is difficult.
