Description

Light material recovery and separation system

Technical Field

The utility model relates to the technical field of material recovery systems, in particular to a light material recovery and separation system.

Background

Laser die cutting machines are becoming more and more widely used because of the following advantages: the laser die cutting is controlled by a computer to cut, is not limited by the complexity of the graph, and can cut the cutting requirement that the traditional cutting die cannot finish; the quick switching between movable parts in different formats can be realized without replacing the cutter template, so that the replacement and adjustment time of the cutter mould of the traditional die cutting are saved, and the method is particularly suitable for short-version and personalized die cutting processing; the cutting graphic design can be completed on a computer, and various graphic parameter settings are automatically generated based on software. Compared with the traditional cutting process mainly generating massive and powdery waste, the laser die-cutting machine is different in shape according to different processed products, and the waste at the rear end is easy to be puzzled.

At present, most factories are used for processing waste materials generated by a laser die-cutting machine in a manner that a material bag is sleeved at the discharge end of the laser die-cutting machine, and the waste materials fall into the material bag by utilizing the dead weight of the waste materials to realize collection. When a certain weight of waste is collected in the bag, a new bag is manually replaced and the old bag is transferred to the waste recovery site. This approach has obvious drawbacks: the more the number of laser die-cutting machines in the factory is, the greater the labor intensity is, and the lower the waste treatment efficiency is; the waste disposal personnel easily interfere with the equipment operators, affecting the operation.

The inventor considers the waste produced by the laser die-cutting machine to be treated by utilizing the dust collector and the negative pressure equipment, negative pressure is produced by the negative pressure equipment to drive air to flow, and the flowing air drives the waste to be transferred to the dust collector through a pipeline, but in the actual research and development process, the paper-shaped waste produced by the laser die-cutting machine is easy to block the filter screen structure of the dust collector due to lighter weight and larger area, so that the air pressure in the whole recovery system is unstable, the waste treatment efficiency fluctuates greatly, and the problem of recovery after separation of paper-shaped waste and dust particles is needed to be treated.

Referring to fig. 11 and 12, the workflow and principles of the present utility model are:

(1) under the operation of the negative pressure equipment 40, air flow continuously flowing towards the negative pressure equipment 40 is generated in the whole system, so that waste generated by the laser die-cutting machine is sucked into the rectifier 10 and then flows back to the vortex separator 20 through the rectifier 10;

(2) when entering the separation chamber 21 from the feed channel 25, the velocity of the dust-containing gas flow is significantly reduced due to the sudden increase in cross-sectional area, so that the dust carrying capacity of the gas flow is reduced, and dust particles with larger particle sizes and scraps of paper are free to settle under the action of gravity. Due to the diversion effect of the diversion section 252, the airflow collides with the inclined wall 28, so that the airflow speed is further reduced, and the sedimentation effect is enhanced. Simultaneously, the inclined wall 28 has a diversion effect, airflow changes direction and flows to the third discharge hole 24, the airflow collides with the inclined wall at the third discharge hole 24, the airflow speed is further reduced, the speed of particles with larger particle size and scraps of paper waste at the position is close to 0, the particles and scraps of paper waste settle at the third discharge hole 24 and are collected by a recycling device, other fine dust rises to the second discharge hole 23 under the continuous extraction of negative pressure equipment, the separation of the scraps of paper waste is completed, and the fine dust flows to the dust collector 30 along with the flowing airflow.

Through the scheme, the negative pressure recovery system is formed by the rectifier 10, the vortex separator 20, the dust collector 30 and the negative pressure equipment 40 which are sequentially communicated, so that the waste of the laser die-cutting machine can be continuously extracted, and automatic waste recovery is realized; by designing the feeding channel 25 in the separation cavity 21, the flow of the dust-containing air flow is guided, so that the scraps of paper can adhere to the wall to flow under the action of inertial centrifugal force when the air flow passes through the arc-shaped upper wall 2521, then flow downwards along the vertical flow section 253, and after entering the separation cavity 21, the scraps of paper and the dust particles with larger micro particle size are separated from the air flow due to the speed reduction of the air flow, so that sedimentation is realized, and especially the scraps of paper cannot flow to the dust collector 30 at the rear end, the system blockage is avoided, the air pressure stability of the whole negative pressure recovery system is ensured, and the whole system can continuously and stably run; the rectifier 10 is used for communicating a plurality of laser die-cutting machines into the system, the waste treatment capacity of the system is greatly improved, and one set of negative pressure recovery system can correspond to the plurality of laser die-cutting machines, so that the purposes of improving efficiency and reducing cost are achieved.
