Suede plastering method for decorative strip of vehicle

Abstract

The invention relates to a velvet sticking method for a decorative strip of a vehicle which conducts flocking after coating glue on a film surface which can carry out thermal bonding with the body of the decorative strip; then the flocked film is cut into the flocked glue belts with needed width; after leading one end of the flocked glue belts to pass through a channel on an extruding die, the one end of the flocked glue belts is exposed out of the extruding opening of the extruding die and the back surfaces of the back ends of the flocked glue belts are caused to be just corresponding to the part needed to be stuck with the velvet of the body of the decorative strip extruded from the extruding opening; with the body of the decorative strip extruded from the extruding opening of the extruding die, the back parts of the flocked glue belts are thermally bonded on the part needed to be stuck with the velvet of the body of the decorative strip. After the scheme is adopted, not only can the device investment and the operation personnel be obviously reduced, the production period is shortened, the production cost and the risk of batch production are reduced, but also the flocking efficiency and the flocking quality of the film can be greatly improved; besides, the working environment is amended, the health of the operation personnel is protected and the machine is avoided from being polluted by the velvet.

Description

technical field [0001] The invention relates to a method for pasting a decorative strip of a vehicle which needs to be flocked. Background technique [0002] Various decorative strips are installed on the existing vehicles. In order to avoid internal noise during driving and improve the interior decoration grade of the automobile, it is necessary to flock the multiple sides of the decorative strips. The main process of the current vehicle decorative strip processing method is as follows: Please refer to Figure 7, first extrude the decorative strip body on the extrusion port of the extrusion die of the extruder 1, and the decorative strip body is cooled by the cooling water tank 2 and drawn by the extraction machine 3 The traction is conveyed to the cutting machine 4, and then the semi-finished product is cut into the required length by the cutting machine 4; then the semi-finished product is sent to the gluing machine 5, and the parts that need flocking are glued; then the f...

AI Technical Summary

Problems solved by technology

[0003] However, the above-mentioned process has the following defects in actual production: (1) when gluing, the glue will inevitably touch the parts that do not need flocking on the decorative strip, so that the parts that do not need flocking are also glued with fluff

Obviously, this not only wastes glue, but also increases the burden of quality inspectors, and it takes time and effort to wipe

In severe cases, the main body of the decorative strip will be scrapped because the glue cannot be wiped clean

(2) Because the cross-section of some decorative strips is very irregular, the fluff is not easy to remove after flocking, causing the fluff to fly and float in the air in the subsequent process, resulting in a poor working environment and bringing great harm to the health of the operators. Hidden dangers, but also not conducive to equipment maintenance

(3) In the extrusion, gluing, and flocking stages of the decorative strip, corresponding personnel need to be assigned to take care of the corresponding equipment, which invisibly increases the production cost; (4) After heat curing, because the glue in the decorative strip is often not It is completely dry, so it cannot be used directly. It is necessary to configure a semi-finished product storage area, which prolongs the process time on the one hand, and provides a more spacious place on the other hand.

(5) After the production of decorative strips is completed, it takes 24 hours to formally judge the quality of flocking, so the risk of bad batches is high and the quality cost is high; (6) Since each production line of the above-mentioned decorative strips needs to be equipped with gluing machine, electrostatic flocking equipment and curing furnace and other processing equipment, so it also has the disadvantages of large equipment investment, many links, complicated process, low efficiency, large power consumption, and high production cost.
