Description

Technical Field

[0001] The invention belongs to the technical field of bamboo toothbrush preparation, and in particular relates to a bamboo toothbrush integrated densification continuous reinforcement device and method. Background Art

[0002] With the shortage of wood resources and the demand for new materials in the market, bamboo has application potential due to its short growth cycle, light weight and high-strength mechanical properties. Under the policy guidance of the "plastic ban", more "bamboo instead of plastic" products have been promoted, more bamboo products have entered the market, and the industrial development of bamboo knives, forks, spoons, toothbrushes and other products has reached a certain scale. Among them, bamboo toothbrushes, as daily necessities, have ecological and environmental value and occupy a certain market. Consumers have higher and higher requirements for the quality of bamboo toothbrushes. The standards for bamboo toothbrush products require beautiful overall structure, burr-free handles and brush heads, and hair bundle tension greater than 15N. In actual production, some bamboo toothbrushes have insufficient hair bundle tension, and hair loss affects use. This is mainly caused by the insufficient strength of the toothbrush handle of the bamboo toothbrush during the hair transplantation process. Due to the anisotropic characteristics of bamboo itself, there are strength differences in the processed blanks during the bamboo toothbrush hair transplantation process. The original bamboo is a cylindrical structure, and the vascular bundles from green to yellow are distributed in a trapezoidal shape. The density of the vascular bundles on the green side is high, and the density of the vascular bundles on the yellow side is low. The vascular bundle is the main structure that contributes to the mechanical properties of the bamboo, such as static bending strength and flexural strength. Therefore, the density of the vascular bundle directly determines the overall strength of the bamboo. The density of natural bamboo is 0.4-0.9g / cm 3 There are differences in density between different bamboo materials and different parts of the same bamboo material. The surface quality of bamboo products directly processed from natural bamboo materials varies greatly. The density of standard bamboo toothbrush products is required to reach 0.7g / cm 3 A considerable portion of bamboo toothbrush handles produced in the existing production lines have a density of 0.6-0.7 g / cm 3 In actual production, the density of bamboo strips purchased is generally distributed between 0.63 and 0.78 g / cm 3 Therefore, more than 95% of bamboo has a density of 0.6g / cm 3 The above can meet the processing requirements. More than 70% of the bamboo toothbrush handles produced in the actual production line can reach the qualified density of bamboo toothbrush products 0.7g / cm 3 Less than 30% of bamboo toothbrush handles have a density below the qualified bamboo toothbrush handle density of 0.7g / cm3, and their surface needs to be densified.

[0003] The uneven density of bamboo toothbrush blanks not only leads to insufficient strength and affects the appearance quality, but also affects the bristle tension of the bamboo toothbrush handle. The bristle tension of bamboo toothbrushes produced by existing bamboo toothbrush production lines is 8 to 20N, which is lower than the bristle tension of more than 15N required by the bamboo toothbrush product standard.

[0004] Moreover, in the current bamboo toothbrush hair planting process, the bristles in the brush holes are fixed by a single layer of aluminum sheet, and a small number of bamboo toothbrush products have insufficient hair bundle tension or even hair shedding. In addition, products that fail the weighing test in the existing production line are treated as waste, resulting in a waste of bamboo materials. In addition, in the grinding and deburring process, the bamboo toothbrush handles are stacked together and put into the grinder for grinding. Although the surface finish of the overall bamboo toothbrush handle can be improved by increasing the processing time, there are differences in the grinding effect of each bamboo toothbrush handle, and some bamboo toothbrush handles still have burr problems on the surface in the subsequent process.

[0005] Based on this, a device and method for continuously strengthening the integrated densification of a bamboo toothbrush are proposed. Summary of the invention
