Cylinder-less paper winder

Abstract

The invention relates to a cylinder-less paper winder, which comprises a frame type stander, a driving motor, a transmission mechanism, a plurality of rollers, an charging device, a paper winding shaft and a control device, wherein the plurality of rollers are arranged in parallel and in pairs; the charging device can be used for holding a paper tube to be wound and the paper tube to be wound can rotate on the charging device so as to unfold external layer paper web in sequence; the paper winding shaft is in a driving connection with the driving motor through the transmission device; and the paper winding shaft is composed of three sections which can be coaxially connected so as to wind the paper tube and can be disconnected to unload the paper tube from the paper winding shaft. The paper winder has a reasonable structure, is easy to manufacture, is simple and convenient for winding operation and can obtain better core-less winding quality, particularly the wound paper tube can be directly dismounted from the paper winding shaft; the working space required by the overall machine is small; and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a paper product processing equipment, in particular to a drumless winding machine. Background technique [0002] The wallpaper produced in batches on the production line is usually a paper tube with a large diameter. When it is sold and used, it only needs a certain length according to the actual needs. For the convenience of use and transportation, it is usually converted into a tube with a smaller diameter; For the paper tube, there are two types of cored and coreless. The cored production process is longer and the production efficiency is lower. After the roll paper is used, the paper or plastic hollow support tube core is discarded as waste, which causes waste of raw materials and Economical waste, the discarded hollow support tube core also causes defects such as environmental pollution. Therefore, now and in the future, paper tubes will mostly adopt coreless paper tubes, that is, the coreless tubes or tubeless tubes des...

[0002] The wallpaper produced in batches on the production line is usually a paper tube with a large diameter. When it is sold and used, it only needs a certain length according to the actual needs. For the convenience of use and transportation, it is usually converted into a tube with a smaller diameter; For the paper tube, there are two types of cored and coreless. The cored production process is longer and the production efficiency is lower. After the roll paper is used, the paper or plastic hollow support tube core is discarded as waste, which causes waste of raw materials and Economical waste, the discarded hollow support tube core also causes defects such as environmental pollution. Therefore, now and in the future, paper tubes will mostly adopt coreless paper tubes, that is, the coreless tubes or tubeless tubes described in the present invention. Most of the equipment for winding rollless roll paper at present adopts the mandrel winding type, and the roll paper principle based on it is mostly called "spoolless core roll paper of roll paper material and its manufacturing method" (patent number: ZL 94101344.8 ) The principle of winding disclosed in the invention patent, which is to feed the web material onto a mandrel, the mandrel has a plurality of axially extending protrusions spaced apart from each other, and the free end of the web material is pressed against the mandrel to start winding, the binder is applied to the pinch rollers, and the web material is pressed between the pinch rollers and the projections of the mandrel, thereby transferring the binder from the pinch rollers to at least the initial portion of the web. On two turns of the web, they are detachably bonded together; the web is wound on a mandrel into a full roll of paper; the roll is cut from the remainder of the web material and the mandrel The paper is pulled out to make a coreless roll paper

Although the existing rolling paper equipment has a high degree of rolling automation, after the rolling is completed, additional special auxiliary equipment is required to take the rolling mandrel out of the rolled paper tube. It will inevitably require a larger working space, and the overall cost is also higher, so it is more suitable for mass production of wallpaper
