Problems solved by technology

[0004] However, in the prior art, in order to combine and fix the bristles in the bristle holes, metal fixtures need to be used, so that when the toothbrush made by the prior art is discarded and recycled, because the plastic brush handle contains metal fixtures, and the metal fixation The size of the parts is small, and it is difficult to take them out from the bristle pores, resulting in quite inconvenient recycling and waste of resources. Therefore, it is necessary to further improve the manufacturing method of the toothbrush in the prior art

[0054] In the present embodiment, the manufacturing method of toothbrush of the present invention is characterized in that:

[0055] In injection molding a brush handle 10A step, see Figure 7 , Figure 8 Figure 9 and Figure 10 As shown, a sheet 13A is formed between the first side 121A of each bristle hole 12A and the second side 112A of the brush head 11A, and a number of recesses are formed on each sheet 13A adjacent to the opposite bristle hole 12A. Each sheet 13A has four rupture portions 131A, each rupture portion 131A extends outward from the center of each sheet 13A, and each rupture portion 131A is connected to form a cross;

[0056] In the step of implanting a bristle portion 20A on the handle 10A, please refer to Figure 9 Figure 10 and Figure 11 As shown, by means of the tufting machine, each bristle 21A penetrates each thin piece 13A of the brush head 11A, so that each thin piece 13A is broken to form several thin fragments 14A, and each bristle 21A is r...

Abstract

The invention relates to a manufacturing method for a toothbrush and the toothbrush manufactured with the method. According to the manufacturing method, a brush holder is formed first through injection molding, a brush head is formed at one end of the brush holder and is provided with multiple brush bristle holes formed integrally, a brush bristle part is implanted in the brush head, the brush bristles of the brush bristle part protrude from a second side face of the brush head, the brush bristles and corresponding thin fragments are fixed to the brush head through hot melting shaping, and finally, an encapsulating part is formed on the brush holder and the second side face of the brush head through injection molding. The toothbrush made with the method, the whole toothbrush is completely made of plastic, the toothbrush can be directly recycled when abandoned, the number of recovery processing steps is reduced and resources are saved.

Description

technical field [0001] The present invention mainly relates to a method for manufacturing a toothbrush, in particular to a method for manufacturing a toothbrush without metal fixing parts. Background technique [0002] The cleaning of the oral cavity is closely related to the health of the human body. To clean the oral cavity, people use tools such as toothbrush, mouthwash and dental floss; wherein, the toothbrush is the basic tool for maintaining oral hygiene. Teeth, and clean the residual food in the teeth, thereby avoiding food residues and bacteria in the mouth, so as to maintain oral hygiene and reduce the occurrence of oral diseases. [0003] The manufacturing method of toothbrush of prior art, it is to form a brush handle with plastic injection earlier, and is formed with several brush pores on the side wall surface of the brush head place of brush handle; The filaments are made into monofilament bristles and assembled into bristle bundles. Taking the implantation po...
