Detailed Description
The following describes in detail a specific embodiment of the apparatus for heat-welding paint brush bristles according to the present invention with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of an apparatus for heat-welding paint brush bristles according to an embodiment of the present invention. Referring to fig. 1, the apparatus for heat-welding coating brush bristles according to the present invention includes a bristle holder 10, a heating unit 20, and a cooling unit 30.
The bristle holder 10 is used to hold a bundle of bristles 100. The bristle bundle 100 may be formed by a plurality of bristles. The bristles may be chemical fiber bristles, and the bristle bundles are chemical fiber bristle bundles. The physical properties of the chemical fiber bristles make them more easily heat-fusible in the subsequent heating step, thereby facilitating heat-fusing. The top view shape of the top end of the bristle bundle may be determined by the shape of the space where the bristle holder 10 is used to fix the bristle bundle, for example, if the shape of the space where the bristle holder 10 is used to fix the bristle bundle is rectangular, the top view shape of the top end of the bristle bundle 100 is rectangular after the bristle holder 10 clamps the bristle bundle 100, and if the shape of the space where the bristle holder 10 is used to fix the bristle bundle is circular, the top view shape of the top end of the bristle bundle 100 is circular after the bristle holder 10 clamps the bristle bundle 100.
Further, in the present embodiment, the bristle fixing clip 10 is a flexible clip, and is sleeved on the outer surface of the top end of the bristle bundle 100, so that the flexible clip can not only clamp the bristles, but also prevent the bristles from separating from the bristle bundle 100 before the bristle bundle 100 is not heated.
The heating device 20 is used to heat the bundle of bristles 100, so that the tip of the bundle of bristles 100 is melted. Specifically, when it is required to heat the bundle of bristles 100, the bundle of bristles 100 or the bristle holder 10 is moved to a position below the heating device 20, the heating device 20 is turned on, the tip of the bundle of bristles 100 is heated, and the tip of the bundle of bristles 100 is melted by heat.
Further, the bristle holder 10 is disposed in a heat propagation direction of the heating device 20. For example, in the present embodiment, the heat propagation direction of the heating device 20 is the lower side thereof, and the bristle holder 10 is located below the heating device 20. When the heating treatment of the bristle bundle 100 is required, the bristle bundle 100 is moved to the bristle holder 10, and the bristle holder 10 holds the bristle bundle.
It is understood that in other embodiments of the present invention, the bristle holder 10 may be movable, and when the heating treatment of the bristle bundle 100 is required, the bristle holder 10 holds the bristle bundle 100 and moves the bristle holder 10 to the lower side of the heating device 20, so as to heat the bristle bundle 100 by the heating device 20.
Further, the heating device 20 is at least one of a heating wire heating device, an infrared heating device, a laser heating device, or an ultrasonic heating device. For example, the heating device 20 is one of a heating wire heating device, an infrared heating device, a laser heating device, or an ultrasonic heating device, or a combination of two or more thereof.
The cooling device 30 can act on the top ends of the bundle of bristles 100 for cooling the melted bundle of bristles 100 and flattening the melted end surfaces. Fig. 2 is a schematic view of the cooling device acting on the melted tip end of the bundle of bristles 100, and referring to fig. 2, after the tip end of the bundle of bristles 100 is melted by the heating device 20, the cooling device 30 is moved above the bundle of bristles 100 and acts on the melted tip end of the bundle of bristles 100 to cool and solidify it and to flatten the melted end surface.
In the present embodiment, the cooling device 30 is a pressure device, which can apply pressure on the top end of the melted bristle bundle 100 to flatten the melted end surface, and the pressure of the pressure device can be controlled to make the melted portion have a preset size, so that the specification of the melted bristle bundle manufactured by the device for thermally fusing the paint brush bristles of the present invention is uniform and meets the requirement. Wherein, the pressure device can be a pressing flat plate and other structures.
Further, the cooling device 30 adopts an air-cooling or liquid-cooling method to improve the cooling efficiency and realize rapid cooling.
Referring to fig. 3, the thermally fused bristle bundle 100 is thermally fused at its top end 101 so that the plurality of bristles are gathered into a bundle and are not dispersed, thereby facilitating subsequent attachment to other structures, such as a paint brush handle.
Further, in the present embodiment, the apparatus for thermally welding the coating brush bristles further includes a feeding device 40, a receiving device 50, and a finished product collecting device (not shown in the drawings).
The feeding device 40 is used to move the bundle of bristles 100 to be heated to the heating device 20 for heating. The feeding device 40 may be used to directly move the bundle of bristles 100 or to move the bristle holder 10 holding the bundle of bristles 100.
The receiving device 50 is used for conveying the thermally fused bristle bundle 100. The receiving device 50 may be used to directly transport the thermally fused bristle bundle 100, or move the bristle holder 10 holding the bristle bundle 100.
The finished product collecting device is used for collecting the thermally fused bristle bundle 100. The receiving device 50 can move the bristle bundle 100 to above the finished product collecting device, and make the bristle bundle fall into the finished product collecting device naturally.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
