阅读说明：本技术 拉链式密闭输送方法 (Zipper type closed conveying method ) 是由 刘毅峰 于 2018-05-30 设计创作，主要内容包括：本发明公开了一种拉链式密闭输送方法,本输送方法由拉链(包括：工业拉链,民用拉链)和传统的各类传送带(也称传输带)及相应设计的、含拉头的、进出料口装置等,这几部分设计构成；本发明的特征是采用了拉链这种密闭方法,改变了人们对普通传送带的传统认知,使得一贯认为是开放性输送的传送带系统成为全密闭的输送系统。(The invention discloses a zipper type closed conveying method, which comprises zippers (including industrial zippers and civil zippers), various traditional conveying belts (also called conveying belts), correspondingly designed devices with sliders and material inlet and outlet ports, and the like; the invention is characterized in that the zipper sealing method is adopted, the traditional cognition of people on common conveyor belts is changed, and the conveyor belt system which is always considered as open conveying becomes a fully-sealed conveying system.)

1. the zipper type closed conveying method is characterized in that a closed covering layer containing a zipper is designed above materials of various traditional conveying belts (also called conveying belts) to form a closed conveying system.

2. the zipper of claim 1 may be: industrial zippers, domestic zippers including metal zippers, various resin zippers, nylon zippers, etc.

3. The conveyor belt of claim 1 may be of any material and form, not limited to those materials and forms commonly used.

4. The method of claim 1, wherein the tape is of a generally concave configuration, a "U" configuration, or an "O" configuration.

5. the zipper design of claim 1, wherein the zipper is double-sided and comprises a secondary zipper that facilitates zipper replacement.

6. The zipper design of claim 1 may be a secondary zipper with a conveniently replaceable covering.

7. The blanket of claim 1 may be a multi-layer blanket design.

8. The covering layer of claim 1 is selected according to different requirements (such as strength, thickness, softness, dust-proof, water-proof, etc.).

9. The slider of the slide fastener according to claim 1 can be industrial grade, specially made by combining various types of rollers; and may be of commercial grade, including metallic and resinous types.

The technical field is as follows:

The method relates to the field of material flow conveying and mechanical manufacturing

Technical background:

The existing closed conveying system comprises pneumatic conveying, pipe chain conveying and pipe belt conveying.

Pneumatic conveying: the one-time investment is high, the operation cost is high, the operation efficiency is low and is limited by the material fluidization characteristic, and the conveying distance is difficult to be slightly far.

conveying by a pipe chain: the one-time investment is high, the long-distance large-conveying-capacity conveying is not suitable, and the operation and the maintenance are inconvenient.

Conveying the pipe belt: the one-time investment is high, and the method is not suitable for medium-short distance conveying.

The design method comprises the following steps:

the traditional belt conveying mode is not closed, the materials are difficult to fly and scatter, and the application is greatly limited due to the problems of workplace and environmental pollution caused by the flying and scattering of the materials;

the design method has the advantages that the feeding, conveying and discharging are operated in a fully-closed mode, and the design method is widely applied. The lower part of the feed inlet device is embedded in an opening of a feed inlet of a zipper in a streamline design; the upper part of the front side of the embedded part of the feed inlet is provided with a pull head which is pulled open, and the rear side is provided with a pull head which is pulled closed; designing a discharge hole in the same way; forming a closed, continuous, closed pull-open and pull-close system; see schematic 6.

The design method can improve the sealing effect by designing a pair of elastic sealing strips under the zipper and adopting a waterproof covering material (such as a rainproof fabric). And a buffering respiration balance system with dust removal function can be designed at an inlet, an outlet or in the middle of the process for factors such as the balance of material space and external pressure difference.

The design method can add an auxiliary zipper design for convenient zipper replacement; when the zipper needs to be replaced, the old zipper is only required to be detached through the auxiliary zipper, and then the new zipper is replaced through the auxiliary zipper.

In the design method, another auxiliary zipper design can be added for conveniently replacing the covering layer; when the covering layer needs to be replaced, only the old covering layer needs to be detached through the auxiliary zipper, and then the new covering layer needs to be replaced through the auxiliary zipper.

in the design method, a second covering layer can be added for conveniently changing the horizontal concave type conveying into the U-shaped conveying in the operation; the multiple overlay design may also be the same or different forms of overlays designed for other purposes. According to design requirements, the running speed is improved, and the service life of equipment is prolonged; the puller can be designed (or selected) as a high-speed industrial puller; see fig. 7. schematic design of industrial pull head. An air flow purge system may also be designed for slider cleaning.
