Layered feeding structure of PET fabric

Abstract

The invention discloses a layered feeding structure of a PET fabric. The layered feeding structure comprises a positioning mechanism, a stepping mechanism, an adsorption mechanism, and a counterweight, wherein the positioning mechanism comprises a bearing plate, positioning needles fixed on the bearing plate, limiting baffles fixed on the edge of the bearing plate, and a mistake-proof shifting plate fixed on the bearing plate, the stepping mechanism comprises a stand column and a forward extension frame fixed on the stand column, the front end of the forward extension frame is fixedly providedwith a guide rod air cylinder, the upper end of one side of the forward extension frame is fixed with a pressure reducing valve, the pressure reducing valve and the guide rod air cylinder are pneumatically connected, the adsorption mechanism comprises a connecting frame, four sucking devices fixed on the two sides of the connecting frame and an induction switch mounted at the front end of the connecting frame, the extending rod end of the guide rod air cylinder is fixed on the connecting frame to drive the adsorption mechanism to move up and down, and the counterweight is fixed on the stand column and is opposite to the fixing direction of the forward extension frame. According to the layered feeding structure of the PET fabric, for a damascene material used in an inlaid injection moldingmanufacturing process and process requirements, a single-layer fabric material can be provided through the structure, so that the full-automatic inlaid injection molding process is further realized,the repeated precision is high, the cost is low, and repair and maintenance are simple.

Description

technical field [0001] The invention relates to the field of inlaid injection molding technology, in particular to a PET fabric layered feeding structure. Background technique [0002] The PET mosaic material used in the mosaic injection molding process is becoming more and more widely used. The PET fabric used is a material with a diameter of 0.8mm woven with a 1X2mm hollow grid structure. The mosaic injection molding process requires a piece of the fabric to be placed in a designated position before forming. In the process of realizing the automatic production of inlaid injection molding, a structure that can provide one piece of this kind of fabric at a time is needed to provide materials for the process. The needle grabbing structure commonly used in the industry is generally a steel needle with a diameter of about 1.5mm. The needles are arranged in an X shape, and the pneumatic energy is used to drive the steel needles to realize the grabbing function. However, due to t...

In the process of realizing the automatic production of inlaid injection molding, a structure that can provide one piece of this kind of fabric at a time is needed to provide materials for the process. The needle grabbing structure commonly used in the industry is generally a steel needle with a diameter of about 1.5mm. The needles are arranged in an X shape, and the pneumatic energy is used to drive the steel needles to realize the grabbing function. However, due to the large hollow size of the fabric, the needle tip is very easy to pierce two pieces of fabric during the grabbing process, which cannot satisfy one piece at a time. fabric needs
