Description

Technical Field

[0001] This utility model relates to the technical field of marking devices, specifically to a new type of marking device for logo design. Background Technology

[0002] In the early stages of logo design, designers primarily rely on traditional hand-drawing tools for line drawing. Simple tools such as rulers, set squares, and compasses, as mentioned earlier, while sufficient for basic line drawing, have limitations. For example, hand-drawing has limited precision; for complex logos requiring high accuracy, it's difficult to guarantee the accuracy and consistency of lines. Furthermore, hand-drawing is inefficient, requiring significant time and effort to draw numerous repetitive or similar lines.

[0003] With the development of industrial technology, mechanical drawing equipment such as plotters emerged. These devices, through mechanical transmission and control mechanisms, can engrave lines onto tools using cutting tools according to a certain program or instruction.

[0004] When changing different cutting tools, existing technology involves disassembling the cutting tools for replacement, which is time-consuming and inefficient. Utility Model Content

[0005] In order to solve the technical problem that the existing technology of replacing different cutting tools by disassembling the cutting tools is time-consuming and has low work efficiency, this utility model provides a new type of marking device for logo design.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A novel marking device for logo design, comprising: a cutter disc, with multiple threaded holes evenly distributed around the side circumference of the cutter disc, different cutting tools connected to the threaded holes by threads, and positioning holes corresponding to the number of threaded holes evenly distributed around the side circumference of the cutter disc, a rotating rod connected to the shaft center of the cutter disc, the rotating rod connected to a spring limiting plate, the spring limiting plate being slidably connected to a sleeve, a spring being sleeved on the rotating rod between the spring limiting plate and the end of the sleeve, the spring being in a compressed state, a limiting rod connected to the end of the sleeve, the limiting rod being able to be inserted into the positioning hole, the sleeve being connected to a tool holder, the tool holder being connected to the drive mechanism of a coordinate plotter, a notched tooth connected to the other end of the rotating rod, a switching rod slidably connected inside the sleeve, a notched tooth connected to the inner end of the switching rod, the notched tooth and the notched tooth being able to be inserted into each other's notches, positioning holes corresponding to the number of threaded holes evenly distributed around the circumference of the rotating rod, a hole being opened on the sleeve, and a pin being able to pass through the hole in the sleeve and be inserted into the positioning hole.

[0007] Preferably, a conical magnet is connected to the upper end of the pin. When notch one and notch two are not engaged, the conical magnet is in contact with the lowest point of the conical surface inside the conical magnetic ring. The conical magnetic ring is connected to the switching rod through a sleeve, and the sleeve is slidably connected to the outside of the sleeve.

[0008] Preferably, the cutting tools include a pen, a laser engraving head, and a carving tool.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] When changing tools, release the axial limit of the pin and the two pairs of sleeves in the positioning hole, press down the switching rod, and after the two notched teeth mesh, the tool disc will be separated from the limiting rod. Then rotate the switching rod to make the tool disc rotate so that the new tool is turned to the working position. Release the switching rod and the tool disc will be radially limited by the limiting rod under the action of the spring. Insert the pin and the tool disc will be fully limited. The plotter will drive the tool to move to realize scribing and engraving. In this way, tool changing can be completed without disassembling the tool, which improves scribing efficiency.

[0011] By using a conical magnet in conjunction with a conical magnetic ring, the switching rod moves, causing the pin shaft to rise and fall automatically. The tool disc can be released or locked as the switching rod moves without the need for manual insertion or removal. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] The following is in conjunction with the appendix Figure 1-2 This embodiment describes a novel marking device for logo design, comprising: a cutter head 1, with multiple threaded holes 2 evenly distributed around its side circumference, each threaded hole 2 having a different cutting tool connected to it; positioning holes 3 evenly distributed around the side circumference of the cutter head 1 corresponding to the number of threaded holes 2; a rotating rod 4 connected to the axis of the cutter head 1; the rotating rod 4 connected to a spring limiting plate 5; the spring limiting plate 5 slidably connected within a sleeve 7; a spring 6 sleeved on the rotating rod 4 between the spring limiting plate 5 and the end of the sleeve 7; the spring 6 being in a compressed state; and a limiting rod connected to the end of the sleeve 7. 8. The limiting rod 8 can be inserted into the positioning hole 1 3. The sleeve 7 is connected to the tool holder 9. The tool holder 9 is connected to the drive mechanism of the coordinate plotter. The other end of the rotating rod 4 is connected to the notch tooth 10. The sleeve 7 is slidably connected to the switching rod 11. The inner end of the switching rod 11 is connected to the notch tooth 2 12. The notch tooth 10 and the notch tooth 2 12 can be inserted into each other's notches. The rotating rod 4 is evenly distributed with threaded holes 2 corresponding to the number of positioning holes 2 13. The sleeve 7 is provided with holes. The pin 14 can pass through the hole of the sleeve 7 and be inserted into the positioning hole 2 13.

[0020] When changing the tool, pull out the pin 14 to release the axial restriction of the pin 14 and the positioning hole 13 on the sleeve 7. Press down the switching rod 11. After the notch tooth 10 and the notch tooth 12 mesh, the tool disc 1 will be separated from the limiting rod 8. The limiting rod 8 will be pulled out through the positioning hole 3 to release the radial restriction of the tool disc 1. Then rotate the switching rod 11 to drive the rotating rod 4 and the tool disc 1 to rotate so that the new tool is rotated to the working position. Release the switching rod 11. Under the action of the spring 6, the limiting rod 8 is inserted into the new positioning hole 3. The tool disc 1 is radially restricted by the limiting rod 8 again. After the pin 14 is inserted, the tool disc 1 is completely restricted. The plotter drives the tool to move to realize scribing and engraving. In this way, the tool can be changed without disassembling the tool, which improves scribing efficiency.

[0021] A conical magnet 15 is connected to the upper end of the pin 14. When notch tooth 10 and notch tooth 2 are not engaged, the conical magnet 15 is in contact with the lowest point of the inner conical surface of the conical magnetic ring 16. The conical magnetic ring 16 is connected to the switching rod 11 through the sleeve 17. The sleeve 17 is slidably connected to the outside of the sleeve 7.

[0022] When the switching rod 11 is pressed down, the switching rod 11 first drives the sleeve 17 and the conical magnetic ring 16 to move. Under the magnetic force of the conical magnet 15 and the conical magnetic ring 16, the conical magnet 15 slides upward along the lowest point of the inner conical surface of the conical magnetic ring 16. The conical magnet 15 drives the pin 14 to be pulled out. The rotation of the conical magnetic ring 16 driven by the switching rod 11 will not affect the position of the conical magnet 15. Then, as the conical magnetic ring 16 is axially reset, the conical magnetic ring 16 drives the pin 14 to be inserted back into the positioning hole 13 through the conical magnet 15. The tool disc can be released or locked with the displacement of the switching rod without manual insertion or removal.

[0023] Tools include pens, laser engraving heads, and engraving tools.

[0024] Switch tools according to different scribing requirements.
