Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of packing paper removing device, especially a kind of packing paper removing device suitable for pulp bag, belong to pulp unpacking technical field in viscose fibre production. BACKGROUND

[0002] Viscose fibre is made of high molecular material wood pulp, cotton pulp etc. containing natural cellulose by chemical and mechanical methods, with soft hand feeling, moisture absorption and air permeability, hanging and floating, bright dyeing, antistatic and easy to textile processing, etc. It is a regenerated cellulose fiber derived from nature and better than nature, and is one of the important materials of textile industry raw materials.

[0003] The process of viscose fibre mainly includes: solid pulp is impregnated to form alkali cellulose, after processes such as squeezing, crushing and aging, it is transported to the yellowing machine to react with CS2 to form cellulose xanthate, then the cellulose xanthate is dissolved in alkali solution to obtain liquid viscose. The viscose is filtered and defoamed to remove impurities and bubbles, and the viscosity and aging degree of the viscose are adjusted through aging process, finally the viscose stock meeting the performance requirements of subsequent spinning process is produced.

[0004] Among them, the raw material pulp is generally stored and transported in the form of pulp bag, so it is necessary to remove the iron wire and packing paper on the pulp bag before use, and then put it into the impregnation barrel. In the production process of viscose stock, it is necessary to remove the iron wire and packing paper. The prior art CN219187281U discloses a "iron wire removing device for pulp bag", which can directly and effectively remove the iron wire outside the pulp bag, providing effective premise guarantee for the feeding of pulp bag in the impregnation process.

[0005] At present, the main ways to remove the packing paper are:

[0006] 1. Manual, time-consuming and labor-intensive, high cost, low efficiency, and unable to guarantee the orderliness and stability of removing the packing paper;

[0007] 2. Adsorption method, due to the special physical properties of packing paper (such as: surface is not smooth. When vacuum chuck is used, negative pressure cannot be formed, and then it cannot be well attached), resulting in low success rate of removing the packing paper;

[0008] 3. Mechanical grabbing method, which is easy to remove part of the pulp together, i.e. the grabbing precision and control of mechanical hand are required to be high;

[0009] And although the prior art "CN219215709U front processing system for pulp bag" discloses that the packing paper removing device includes a paper skin suction device and a third support, the second swing arm is arranged on the third support, but the success rate of removing the packing paper is not high, and the efficiency is low.

[0010] Therefore, a device for removing the packaging paper from the pulp bag with high efficiency, high quality and automation is needed. SUMMARY

[0011] In order to solve the problems of low efficiency, high cost, and low success rate of removing the packaging paper (e.g., due to the difficulty in separating the pulp from the packaging paper when grabbing the packaging paper, which easily removes part of the pulp) of the existing packaging paper removing device, a device for removing the packaging paper from the pulp bag is proposed. By setting the tooth-shaped paper taking mechanism and the moving mechanism, the device not only ensures high efficiency of removing the packaging paper, but also ensures effective removal of the packaging paper from the pulp bag, providing effective premise guarantee for pulp feeding in the impregnation process.

[0012] In order to achieve the above technical purpose, the following technical scheme is proposed:

[0013] A device for removing the packaging paper from the pulp bag is provided on one side of the pulp bag conveying mechanism, which includes a mounting column, a tooth-shaped paper taking mechanism, and a moving mechanism for moving the tooth-shaped paper taking mechanism.

One end of the swing arm type moving frame is movably connected to the mounting column, and the other end is connected to the longitudinal moving frame.

[0014] The tooth-shaped paper taking mechanism includes a mounting plate and at least two groups of toothed clamping pieces. The mounting plate is provided at the lower end of the longitudinal moving frame, and the toothed clamping pieces are evenly distributed on the mounting plate. In one group of toothed clamping pieces, the toothed clamping pieces are distributed on opposite sides of the mounting plate.

The teeth of the oppositely distributed toothed clamping pieces are opposite to each other.

[0015] A clamping cylinder is provided on the mounting plate to drive the toothed clamping pieces to clamp or release the packaging paper.

[0016] The moving mechanism drives the tooth-shaped paper taking mechanism to move up and down, forward and backward (multi-directional movement), which on one hand aligns the tooth-shaped paper taking mechanism with the pulp bag whose packaging paper is to be removed, facilitating the subsequent smooth removal of the packaging paper; on the other hand, after the packaging paper is removed from the pulp bag, it ensures smooth removal and transfer.

Wherein, the clamping cylinder provides power and drives the rack to move, and the rack drives the gear to rotate, and the gear drives the rotating shaft to rotate, and finally the rotating shaft drives the toothed clamping piece to clamp or release the packaging paper.

[0018] Further, the rotating shaft is arranged in the center through hole of the gear.

[0023] Further, the displacement sensor is arranged at the pulp bag pause station of the pulp bag conveying mechanism, for monitoring the pulp bag to be removed from the packaging paper. For example, after the pulp bag to be removed from the packaging paper is conveyed to the pulp bag pause station, the displacement sensor transmits the detected signal to the central processor, the central processor controls the motor of the conveying mechanism to stop working, that is, the conveying mechanism stops working, so that the pulp bag to be removed from the packaging paper is paused; at the same time, the central processor controls the corresponding motor and cylinder of the packaging paper removing device to work, and removes the packaging paper.

[0024] Further, the swing arm type moving frame is connected with the installation stand through the horizontal swing cylinder.
