Abstract: A flat-pen automatic assembly line system includes a worktable, two sprockets, and an endless loop driving chain connecting the two sprockets. The two sprockets are mounted at the two ends of the worktable, respectively. A plurality of jigs on the driving chain receives pen barrels. A transporting rail supporting the driving chain is provided between the two sprockets. A pen-cap mounting station and a pen-cap pressing station are provided on the same worktable successively, and the pen-cap pressing station is provided with an automatic pen-cap pressing machine. The pen-cap mounting process and the pen-cap pressing process are completed on the same worktable and these two processes are linked via the same driving chain. Therefore, the assembly time is shortened and the assembly efficiency is improved. Furthermore, the pen-cap pressing process may employ an automatic pen-cap pressing machine. Therefore, labor can be reduced further, and assembly efficiency can be improved.

Abstract: A vibrating device for uniformly filling granular ornaments includes a base, a vibration platform, a motor, a first vibrating assembly for generating vibration in an up-down direction, and a second vibrating assembly for generating vibration in a left-right direction. The vibration platform is articulated at the base and provided with multiple through-holes for holding workpieces, such as pen caps. The motor is fixedly mounted at the base. The first vibrating assembly and the second vibrating assembly both are provided between the motor and the vibration platform. The motor drives the first vibrating assembly to make the vibration platform vibrate in the up-down direction, and at the same time drives the second vibrating assembly to make the vibration platform vibrate in the left-right direction. Thus, granular ornaments can fill the cavities of pen caps located within the through holes in the vibration platform.

Abstract: A heat transferring device for a workpiece such as a pen barrel includes a pneumatic mechanism, a roller mechanism, a heating mechanism, and a rolling mechanism. The pneumatic mechanism is connected with the roller mechanism. The rolling mechanism rotates the pen barrel, and the roller mechanism includes an elastic force applying mechanism that applies an elastic force on the pen barrel during rotation. As the rolling mechanism rotates the pen barrel, the elastic force applying mechanism applies an elastic force to the pen barrel that keeps a roller wheel in contact with respective faces of the pen barrel during rotation. Thus, the force that the elastic force applying mechanism applies to the pen barrel is uniform and the respective faces of the pen barrel receive a uniform force. Therefore, the device can heat transfer designs on pen barrels having non-circular as well as circular shapes.

Abstract: A paint for spraying on bamboo products, such as on the exterior surface of a slim tube-shaped bamboo product, is a nonaqueous acrylic-based paint including 10 to 15 percent by weight of one or more flatting powders, 50 to 55 percent by weight of one or more acrylic resins, 1 to 5 percent by weight of one or more leveling agents, 13 to 16 percent by weight of one or more ester solvents, 10 to 15 percent by weight of one or more alcohol solvents, and 8 to 10 percent by weight of one or more ether solvents. After application of the wet paint composition, the solvents evaporate leaving a film of the acrylic resins, flatting powders, and leveling agents.
