An apparatus for foaming dyeing of foamed plastic uniformity

Abstract

This utility model discloses a foam plastic uniform foaming and dyeing device, including a support frame. An inclined dyeing chamber is fixedly connected to the top of the support frame. A feed hopper is fixedly connected to one side of the dyeing chamber. A partition plate is inserted through the middle of the dyeing chamber. A first power unit for driving the partition plate to rise and fall is installed on the side wall of the dyeing chamber. In this utility model, when the first driving cylinder is activated, the piston end of the first driving cylinder moves the partition plate via a second mounting block, preventing the partition plate from obstructing the foam plastic. The foam plastic falls to the side near the sealing end plate. Then, the partition plate is reset. At this time, foam plastic can continue to be fed into the feed hopper, allowing continuous mixing of the foam plastic with the mixed solution. Subsequent mixing and drying are carried out simultaneously, improving work efficiency.

Description

Technical Field

[0001] This utility model relates to the field of foam plastics technology, and in particular to a foam plastic uniform foaming and dyeing device. Background Technology

[0002] Foamed plastics are a type of polymer material formed by dispersing a large number of gas micropores within solid plastic. They possess properties such as light weight, heat insulation, sound absorption, and shock absorption, and their dielectric properties are superior to those of the matrix resin, making them widely applicable. Almost all types of plastics can be made into foamed plastics, and foam molding has become an important field in plastics processing.

[0003] Patent publication number CN220562022U discloses a foam plastic uniform foaming and dyeing device, including a cylinder and a foaming and dyeing mechanism. A discharge cover is located at the bottom center of the cylinder, and a reinforcing block is connected to the lower surface of the discharge cover. A sliding groove is opened on the rear side of the bottom of the cylinder, and a slider is connected inside the groove. The control panel operates, with a motor driving a second gear to rotate. A second stirring rod continuously stirs the foam plastic inside the cylinder. The foaming agent, foaming agent, and dyeing agent are uniformly mixed in a mixing tank by the first stirring rod. The mixture is then evenly sprayed through a nozzle to ensure thorough mixing with the foam plastic, resulting in more uniform dyeing. Subsequently, a fan and heating plate are activated to provide favorable conditions for foaming, improving the foaming effect. Finally, the slider is pushed to one end of the large through-hole in the reinforcing block, opening the discharge cover and removing the uniformly foamed and dyed foam plastic. The device has a simple structure, is convenient and quick to operate, and can reduce labor and maintenance costs.

[0004] However, the aforementioned patent requires that the foam plastic be thoroughly mixed with the mixed solution before the foam plastic is discharged after it has foamed, which makes continuous operation impossible and results in low foaming and dyeing efficiency. Utility Model Content
