Description

Technical Field

[0001] This utility model relates to the field of thermal paper production technology, and in particular to a line marking device for a thermal paper slitting machine. Background Technology

[0002] Thermal paper is a dedicated consumable for digital multifunction printers. It features high efficiency, convenience, environmental friendliness, and economy. Its production process includes lamination, slitting, marking the start and end of printing lines, and packaging. Slitting involves cutting the laminated thermal paper semi-finished rolls into smaller rolls of the appropriate width and length required by the digital multifunction printer. The start and end marks are formed by drawing lines on the beginning and end sections of each roll of thermal paper, respectively, and are used by the digital multifunction printer to identify the start and end of printing.

[0003] Currently, some factories use manual drawing to mark the start and end points on thermal paper, which is time-consuming, labor-intensive, and inefficient.

[0004] Some factories use a drawing pen fixed on the slitting machine during the slitting process to draw lines, and manually adjust the distance between the pen tip and the thermal paper to ensure the pen tip contacts and presses against the paper, thus completing the drawing action. However, the existing drawing pens store ink in a fiber ink guide tube inside the pen tube. If continuous production is carried out and the amount of lines drawn is large, the amount of ink used is also large. Because the ink storage capacity is small, the drawing pen needs to be removed frequently to refill the ink multiple times, which significantly increases the number of production interruptions and seriously affects production efficiency. Utility Model Content

[0005] To address the aforementioned problems, this invention provides a line-drawing device for a thermal paper slitting machine. This device not only avoids manual line drawing but also effectively extends the continuous line-drawing time through an ink reservoir, thereby reducing production interruptions and improving production efficiency. It also facilitates ink replenishment.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] This utility model provides a line-drawing device for a thermal paper slitting machine, including a frame of the slitting machine and a line-drawing pen body mounted on the frame for drawing lines on thermal paper. It also includes a drive mechanism and an ink reservoir for supplying ink to the line-drawing pen body. The ink reservoir includes a cap and an upper and lower opening respectively communicating with its inner cavity. The cap is detachably fitted onto the upper opening, and the end of the line-drawing pen body opposite to the pen tip is fitted onto the lower opening. The drive mechanism is mounted on the frame and drives the line-drawing pen body so that the pen tip of the line-drawing pen body presses against the thermal paper to form a line drawing on the thermal paper.

[0008] Furthermore, both the upper and lower openings of the ink reservoir are threaded, the cap is detachably screwed to the upper opening, and the end of the drawing pen body facing away from the pen tip is detachably screwed to the lower opening.

[0009] Furthermore, the driving mechanism includes a driver, a connecting rod, a support frame, and a rotating shaft rotatably mounted on the support frame. The support frame is mounted on the frame, and the driver is rotatably connected to the frame. The drive shaft of the driver is rotatably connected to one end of the connecting rod, and the other end of the connecting rod is fixed to the rotating shaft. The upper part of the drawing pen body away from the pen tip is fixed to the rotating shaft. The driving mechanism drives the drawing pen body to rotate, so that the pen tip of the drawing pen body switches between abutting and moving away from the thermal paper.

[0010] Furthermore, the driver is a cylinder or a servo motor assembly.

[0011] Furthermore, the ink storage bottle is a plastic bottle or a glass bottle.

[0012] The technical solution provided by this utility model has the following beneficial effects:

[0013] The driving mechanism drives the pen tip of the drawing pen body to press against the thermal paper, thereby enabling lines to be drawn on the thermal paper and avoiding manual drawing.

[0014] The ink pen body is supplied with ink through an ink reservoir filled with sufficient ink, ensuring that the pen tip can continuously draw ink on the thermal paper for a sufficiently long time, thereby effectively extending the continuous drawing time and reducing the number of production interruptions, thus improving production efficiency. At the same time, the upper opening of the ink reservoir is equipped with a detachable cap to facilitate the replenishment of ink. The structure is simple and easy to operate.

[0016] Figure 2 As shown Figure 1 Enlarged diagram of area A in the middle. Detailed Implementation

[0017] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0019] Reference Figure 1 and Figure 2 As shown, this embodiment provides a line drawing device (hereinafter referred to as the line drawing device) for a thermal paper slitting machine. The line drawing device includes a frame 7 of the slitting machine and a line drawing pen body 3 mounted on the frame 7 for drawing lines on thermal paper 8. The line drawing device also includes a drive mechanism 13 and an ink reservoir 1 for supplying ink to the line drawing pen body 3. The ink reservoir 1 includes a cap 2 and an upper bottle opening 11 and a lower bottle opening 12 that respectively communicate with its inner cavity. 12 is configured as upper and lower. The bottle cap 2 is detachably closed onto the upper bottle opening 11. The bottle cap 2 is used to seal the upper bottle opening 11 to prevent the ink in the ink storage bottle 1 from evaporating. The upper end of the drawing pen body 3, away from the pen tip 31, is assembled onto the lower bottle opening 12. In addition, the drive mechanism 13 is mounted on the frame 7. The drive mechanism 13 drives the drawing pen body 3 so that the pen tip 31 of the drawing pen body 3 presses against the thermal paper 8 to form a drawing setting on the thermal paper 8.

[0020] In this embodiment, the drive mechanism 13 includes a driver 5, a connecting rod 9, a support frame 10, and a rotating shaft 4 rotatably mounted on the support frame 10. The support frame 10 is mounted on the frame 7. The driver 5 is rotatably connected to the frame 7. Specifically, the driver 5 is a cylinder. The drive shaft of the driver 5 is rotatably connected to one end of the connecting rod 9, and the other end of the connecting rod 9 is fixed to the rotating shaft 4. The upper part of the drawing pen body 3 away from the pen tip 31 is fixed to the rotating shaft 4 through a connector. The drive mechanism 13 drives the drawing pen body 3 to rotate so that the pen tip 31 of the drawing pen body 3 switches between the position of contacting and moving away from the thermal paper 8. In addition, the ink storage bottle 1 is a plastic bottle to effectively reduce the probability of the ink storage bottle 1 breaking or leaking ink due to accidental collision or falling to the ground.

[0021] Furthermore, the ink volume of the ink reservoir 1 is greater than the maximum ink volume contained in the ink core of the drawing pen body 3. The ink in the ink reservoir 1 is continuously introduced into the ink core of the drawing pen body 3 through the lower opening 12 of the ink reservoir 1, so as to supply or add ink to the ink core of the drawing pen body 3, thereby ensuring that the pen tip 31 of the drawing pen body 3 can continuously output ink.

[0022] The driving mechanism 13 drives the pen tip 31 of the drawing pen body 3 to press against the thermal paper 8, so as to draw lines on the thermal paper 8 and thus avoid drawing lines by hand.

[0023] The ink bottle 1, which is filled with sufficient ink, is used to supply ink to the drawing pen body 3, so as to ensure that the pen tip 31 of the drawing pen body 3 can continuously produce ink on the thermal paper 8 for a long enough time, thereby effectively extending the continuous drawing time and reducing the number of production interruptions, thus improving production efficiency. At the same time, the upper opening 11 of the ink bottle 1 is equipped with a detachable cap 2 to facilitate the replenishment of ink to the ink bottle 1. The structure is simple and easy to operate.

[0024] Of course, in other embodiments, the driver 5 may also be a servo motor assembly, and the ink reservoir 1 may also be a glass bottle, which will not be described in detail here.

[0025] In another preferred embodiment, the upper opening 11 and lower opening 12 of the ink reservoir 1 are both provided with threads. The cap 2 is detachably screwed to the upper opening 11, and the upper end of the drawing pen body 3 is detachably screwed to the lower opening 12. Through the threaded connection, the lower opening 12 of the ink reservoir 1 is connected to the ink inlet of the ink core of the drawing pen body 3, so as to realize the quick disassembly and assembly of the drawing pen body 3. In this way, ink filling is simpler, more convenient and more time-saving, thereby improving the convenience of operation and work efficiency.

[0026] In this specific embodiment, when it is necessary to draw lines, the control system of the slitting machine gives a line drawing start command and controls the driver 5 to turn on. The driver 5 pushes the rotating shaft 4 on the support frame 10 to rotate clockwise to a certain angle so that the pen tip 31 of the drawing pen body 3 presses on the thermal paper 8 on the line drawing guide roller 6 of the slitting machine. The line drawing ink extends along the winding direction under the traction force of the thermal paper 8 winding and unwinding.

[0027] When the line length reaches the preset value, the slitting machine's control system issues a line drawing end command and controls the driver 5 to shut down. The driver 5 pulls the rotating shaft 4 to rotate counterclockwise to a certain angle so that the pen tip 31 of the drawing pen body 3 leaves the thermal paper 8 on the drawing guide roller 6, thus ending the line drawing.

[0028] When the ink in the ink reservoir 1 is about to run out, unscrew the cap 2 of the upper opening 11 of the ink reservoir 1, and pour the ink into the ink reservoir 1 through the upper opening 11 using a funnel or directly. After adding the ink, tighten the cap 2 again to seal the upper opening 11 of the ink reservoir 1 to prevent ink from splashing out when drawing lines. It is also convenient to operate as there is no need to remove the drawing pen body 3 and the ink reservoir 1 to refill the ink.

[0029] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
