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 fountain-pen automatic assembly line system includes a worktable, two sprockets, and an endless loop driving chain connecting the two sprockets. The sprockets are mounted at two ends of the worktable respectively. A plurality of jigs is provided on the driving chain, wherein the jigs are configured to hold fountain pen barrels. A transporting rail supporting the driving chain is provided between the two sprockets, and the transporting rail is fixed on the worktable. An ink-reservoir mounting station and an ink-reservoir pressing station are provided on the worktable successively. The ink-reservoir mounting station is provided with an automatic ink-reservoir mounting machine, and the ink-reservoir pressing station is provided with an automatic ink-reservoir pressing machine. The ink-reservoir mounting process and the ink-reservoir pressing process are linked via the driving chain, so that the assembly time is shortened and the assembly efficiency is improved.

Abstract: Embodiments of ink-filling devices are described. An ink-filling device may include a feeding-stock arranging track configured to stack workpieces in a single file. An ink-filling needle is configured to move from a first position opposite from the feeding-stock arranging track to a second position within the feeding-stock arranging track. A push rod is configured to move from a first position opposite from the feeding-stock arranging track to a second position within the feeding-stock arranging track. The devices may be used for filling with ink the absorbent wrap-around cores used in writing instruments.

Abstract: Disclosed peening machines may include a first disc having grooves on a periphery of the disc, wherein the grooves are configured to hold a first workpiece; a second disc having grooves on a periphery of the disc, wherein the grooves are configured to hold a second workpiece. The first and second discs are coaxially aligned with each other and a groove of the first disc is positioned to be aligned with a groove of the second disc. A first reciprocating push rod is positioned to be aligned with a groove of the first disc, a second reciprocating push rod is positioned to be aligned with a groove of the second disc, and a reciprocating peening needle is positioned perpendicular to the first and second pushrods. The peening machine may assemble metal pen tips to ink guide cores by peening the metal pen tips to the ink guide cores.

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 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.
