[0019] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.
[0020] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0022] See also Figures 1 to 4 The present invention provides a ballpoint pen and a fixed paintbrush knife barrel that can automatically eject a single ballpoint pen. The pen comprises a ballpoint pressing device 1, a ball storage barrel 2, and a pen tip 5. A barrel cover 9 is connected to the top of the ball storage barrel 2. The ballpoint pressing device 1 passes through the barrel cover 9 and is fixed to the ball storage barrel 2. The ballpoint pressing device 1 and the ball storage barrel 2 have an interference fit. The pen tip 5 passes through the ball storage barrel 2 and is fixed to the ball storage barrel 2 via a guide pin 3. The pen tip 5 and the ball storage barrel 2 have a clearance fit. The ballpoint pressing device 1 is provided with a hole that cooperates with the guide pin 3. The ballpoint pressing device 1 cooperates with the paintbrush knife barrel to realize the ball-pressing function. The purpose of the bead storage barrel 2 is to store beads 7, and a hole that cooperates with the guide pin 3 is provided therein.
[0023] like Figure 2 and Figure 3 As shown, the bead tip 5 is provided with a bead guide groove 11 to facilitate single bead ejection. This guide groove is L-shaped, with a bead inlet 10 at its top. The shaft of the bead tip 5 is provided with a slot that mates with a guide pin 3. The guide pin 3 connects the various components and provides guidance for the bead tip 5. The width of the bead guide groove 11 is slightly larger than the diameter of a single bead 7, so that only one bead 7 can enter.
[0024] like Figure 1 As shown, a return spring 4 is installed between the bead storage tube 2 and the guide pin 3. It provides power for the pen tip 5 to be reset.
[0025] like Figure 1 As shown, a reset screw is installed on the pen tip 5, and the reset screw adopts a quick-change reset screw to prevent the beads 7 from falling when not working.
[0026] A fixed paintbrush knife barrel comprises a paintbrush knife barrel 8 and a ballpoint pen fixed on the paintbrush knife barrel 8 and capable of automatically ejecting a single ball as described above.
[0027] Installation: The bead pressing device 1 passes through the barrel cap 9, and the bead tip 5 passes through the bead storage barrel 2, connecting them via the guide pin 3. The hole and the shaft are a tight fit, securing the bead pressing device 1 and the bead storage barrel 2. The hole and the groove are a sliding fit, allowing the bead tip 5 to slide relative to each other. A return spring 4 is installed between the bead storage barrel 2 and the guide pin 3, and a self-resetting screw 6 is threadedly mounted on the bead tip 5. It is important to note that the barrel cap 9 and the bead storage barrel 2 are connected by threads.
[0028] Working principle: This ballpoint pen needs to be used with a fixed brush knife cylinder with a clamping hole. The upper end of the ballpoint pressing device 1 cooperates with the fixed brush knife cylinder. After the two are assembled, they are installed on the knife seat of the digital cutting machine and can be controlled by the system to press the beads 7 at a fixed point on the material. Figure 4 The figure shows the state of using a ballpoint pen and a fixed brush knife barrel together.
[0029] Working state: When the ballpoint pen is used in conjunction with a fixed brush barrel, the bead pressing device 1 is fixed to the fixed brush barrel. At this time, if the ballpoint pen is pressed downward, its lower end component will move along the axis, and at the same time, the ball 7 inside the ballpoint pen will be squeezed into the material as the bead pressing device 1 is pressed downward; when the ballpoint pen moves upward, the return spring 4 will reset the pen tip 5 downward. Figure 2 The figure shows the state of the ballpoint pen when it is not working (the ballpoint pen moves upwards). Figure 3 The figure shows the working state of the ballpoint pen (if the ballpoint pen is pressed down).
[0030] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
