Patent number: 11351706Abstract: A system comprises a fully automated fabrication cell (20) for forming overmolded oral care implements. The cell (20) includes a cluster of process stations (21) including injection molding machines operable to first form oral care implement preforms and then overmold the preforms with an overlay to create fully formed oral care implement bodies. In one example, the overlay may be a flexible elastomeric or rubber material while the preform may comprise a more rigid plastic material. Transfer of the preforms and bodies between the process stations (21) is fully automated and performed by a computer-operated robot (40) having a jointed articulated arm. A grasping tool (60) disposed on an end of the arm (42) releasably engages and transports a plurality of preforms and/or bodies simultaneously. The tool provides two different methods for engaging and holding the toothbrush skeletons/bodies. A programmable controller (130) automatically controls the robotic arm (42)'s operation and movement.Type: GrantFiled: November 2, 2016Date of Patent: June 7, 2022Assignee: Colgate-Palmolive CompanyInventors: Peng Wang, Shiyong Xia, Tao Xie

Publication number: 20150361217Abstract: The present invention discloses a polyamide resin and its application and polyamide composition thereof. The repeating units of the described polyamide resin comprises the following components: dicarboxylic acid units composed 80-100 mol % of polyamide resin; aliphatic diamines units having 2-14 carbon atoms composed 80-100 mol % of polyamide resin; lactam or amino acid units having 6-14 carbon atoms composed 0-20 mol % of polyamide resin; in the described polyamide resin, the bio-based carbon concentration is more than 45%; the described bio-based carbon mole concentration is calculated according to the formula below: bio-based carbon concentration=(bio-based carbon mole content/total organic carbon mole content)*100%. The described polyamide resin in the present invention has low gas volatile, hence the polyamide composition produced thereof has low gas volatile too, and can be applied to food-contact field.Type: ApplicationFiled: January 10, 2014Publication date: December 17, 2015Inventors: Chuanhui ZHANG, Tongmin CAI, Xiangbin ZENG, Min CAO, Shiyong XIA, Nanbiao YE, Dahua CHEN, Shaoyan YUAN

Patent number: 8557945Abstract: The present invention relates to a kind of biodegradable polyester and its preparation method, which belongs to the field of biodegradable co-polyester product technology. The number-average molecular weight of the biodegradable polyester material under this invention is 6000-135000 g/mol, the molecular weight distribution is 1.2-6.5, and the range of crystallization temperature is 15° C.-105° C., which could overcome the disadvantages of existing technical products and can be processed into membrane materials, sheet materials and foam materials. During processing, the picking property will be dramatically changed with the appearance quality improved; after heat resistance is improved, this new type of polyester material could also be applied to the processing course with long cycles, for example, the injection processing course, and the biodegradable aliphatic/aromatic polyester materials provided by this invention has excellent mechanical properties.Type: GrantFiled: May 15, 2009Date of Patent: October 15, 2013Assignees: Kingfa Science & Technology Co., Ltd, Shanghai Kingfa Science & Technology Co., LtdInventors: Yibin Xu, Renxu Yuan, Tongmin Cai, Jian Jiao, Shiyong Xia, Zhimin Yuan

Patent number: 8420772Abstract: The present invention relates to a semi-aromatic polyamide and a method for preparing it with low wastewater discharge. The semi-aromatic polyamide for the present invention is obtained by introducing aromatic dicarboxylic acid, aliphatic diamine containing 4˜14 carbon atoms and the wastewater generated during the previous prepolymerization into an autoclave for prepolymerization reaction and then further polymerizing the prepolymer. In this preparation method, the wastewater generated during polymerization is recycled, thus greatly reducing the wastewater discharge; the raw materials in the wastewater are effectively recycled, thus improving the utilization rate of raw materials; meanwhile, the diamine in the wastewater compensates that lost along with water discharge during prepolymerization, thus ensuring the Mole ratio balance between dicarboxylic acid monomer and diamine monomer.Type: GrantFiled: July 11, 2008Date of Patent: April 16, 2013Assignees: Kingfa Science & Technology Co., Ltd, Shanghai Kingfa Science & Technology Co., LtdInventors: Min Cao, Shiyong Xia, Xianbo Huang, Tongmin Cai, Xiangbin Zeng
