Abstract

The invention relates to the technical field of flocking processes, in particular to waste velvet collecting equipment for flocking processes, which comprises a machine base, an air suction pump fixedly arranged on the machine base, a fixing frame for fixing the machine base on a flocking device, a dust suction pipe communicated with an air inlet end of the air suction pump, a collecting mechanism for separating velvet from dust, wherein the collecting mechanism comprises a collecting pipe, a material taking groove arranged on the side surface of the collecting pipe, a sealing plate for sealing the material taking groove, a fixing piece for fixing the sealing plate, a rubber ring arranged at one end of the collecting pipe, a connecting block for fixing the collecting pipe on a flocking box, a dust collecting hopper for communicating the collecting pipe with the dust suction pipe, and a collecting piece arranged on the collecting pipe. In the invention, after the air flow mixed with the fluff and the dust is mixed into the collecting pipe, the spiral blades block and buffer the air flow, so that the speed of the air flow mixed with the fluff and the dust is reduced after the air flow enters the screen cylinder, and further, enough time is provided for the screen cylinder to separate the fluff from the dust, thereby improving the separation effect.

Description

Waste velvet collecting equipment for velvet planting technology Technical Field The invention relates to the technical field of flocking processes, in particular to waste velvet collecting equipment for flocking processes. Background The flocking process is a processing technology for vertically implanting short fiber fluff into the surface of a base material coated with an adhesive through electrostatic action, and is widely applied to industries such as spinning, automotive interior, packaging, toys and the like. The principle is that the fluff is charged by a high-voltage electrostatic field, and flies vertically to the substrate under the action of electric field force, the root of the fluff is inserted into the adhesive, and the fluff is firmly attached to the surface of the substrate after baking and solidification, so as to form a suede effect. In the flocking process, the collection and treatment of waste velvet are important links, and not only relate to cost control and environmental protection, but also directly influence the production environment and the product quality. The existing waste velvet collecting method is a fixed-point negative pressure suction method, air suction ports are formed in the bottom and the sides of a flocking box/chamber, and the negative pressure generated by a fan is used for directly sucking down the velvet which cannot be implanted or naturally falls down, so that the velvet is prevented from flying in the box, but fine velvet and dust are mixed and are not easy to separate. Therefore, there is a need to provide a new solution to overcome the above-mentioned drawbacks.
