Description

Technical Field

[0001] This utility model relates to the field of drawing printer technology, and in particular to a spring-fixed paper take-up shaft structure. Background Technology

[0002] A plotter printer is a device that draws according to graphics input into a system, capable of printing computer-generated information in graphic form. With the support of plotting software, plotter printers can produce complex and precise graphics, making them an indispensable tool for various computer-aided design tasks. For industries requiring large printouts, such as garment patterns, cardboard box samples, and large outdoor advertising designs, roll-type printing paper is often used. This type of plotting printing typically requires a take-up reel to rewind the printed paper, and the rewinding action pulls the paper forward to complete the printing process. However, because the take-up reel needs frequent disassembly and assembly, and the existing take-up reel fixing structure is relatively complex, disassembly and assembly are time-consuming.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a spring-fixed paper take-up shaft structure.

[0005] The technical solution of this utility model is as follows: A spring-fixed paper take-up shaft structure is provided, including: a machine base, a paper take-up structure disposed on the machine base, and a paper take-up shaft movably disposed on the paper take-up structure. The paper take-up structure includes: mounting plates disposed on both sides of the machine base, a U-shaped bracket disposed on one side of the mounting plate, a telescopic rod passing through the U-shaped bracket, and a spring disposed between the U-shaped bracket and the telescopic rod. The telescopic rod passes through the U-shaped bracket and the mounting plate in sequence and contacts the end of the paper take-up shaft. The spring pushes the telescopic rod toward the paper take-up shaft.

[0006] Furthermore, the telescopic rod includes a guide end, a limiting end, and a fixed end. The guide end passes through the U-shaped bracket, the fixed end passes through the mounting plate and contacts the end of the paper receiving shaft, one side of the limiting end contacts a spring, and the other side is in movable contact with the mounting plate. The spring is sleeved on the guide end.

[0007] Furthermore, the end of the telescopic rod facing the paper take-up shaft is a conical structure, and the paper take-up shaft is provided with a positioning hole corresponding to the conical structure, and the conical structure is movably embedded in the positioning hole.

[0008] Furthermore, a U-shaped seat is provided on the side of the mounting plate facing the paper take-up shaft, and the end of the paper take-up shaft is placed on the U-shaped seat.

[0009] Furthermore, a drive mechanism is provided on the mounting plate at the end without the U-shaped bracket, and the output end of the drive mechanism is in active contact with the paper take-up shaft.

[0010] By adopting the above solution, this utility model uses a spring to drive the telescopic rod to move towards the paper take-up shaft, so as to press and fix the paper take-up shaft, which effectively improves the disassembly and assembly efficiency of the paper take-up shaft and facilitates the disassembly and assembly work. At the same time, it effectively improves the efficiency of printing drawings and reduces the time required to replace the corresponding paper take-up shaft after each printing and cutting of the drawings.

[0013] Figure 3 This is a schematic diagram of the telescopic rod. Detailed Implementation

[0014] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Please see Figure 1 , Figure 2 This utility model provides a spring-fixed take-up shaft structure, including: a machine base 1, a take-up structure 2 disposed on the machine base 1, and a take-up shaft 3 movably disposed on the take-up structure 2. The take-up structure 2 includes: mounting plates 21 disposed on both sides of the machine base 1, a U-shaped bracket 22 disposed on one side of the mounting plate 21, a telescopic rod 23 passing through the U-shaped bracket 22, and a spring disposed between the U-shaped bracket 22 and the telescopic rod 23. The telescopic rod 23 passes through the U-shaped bracket 22 and the mounting plate 21 in sequence and contacts the end of the take-up shaft 3. The spring pushes the telescopic rod 23 toward the take-up shaft 3. When the take-up shaft 3 needs to be installed, one end of the take-up shaft 3 can be placed on the mounting plate 21 without the U-shaped bracket 22, and the other end can be placed on the mounting plate 21 with the U-shaped bracket 22. At the same time, the telescopic rod 23 is pulled outward to allow it to move and facilitate the placement of the take-up shaft 3. Then, release the telescopic rod 23. Under the elastic action of the spring, the telescopic rod 23 moves towards the take-up shaft 3, thereby tightening and fixing the take-up shaft 3, thus achieving the installation and fixation of the take-up shaft 3. When it is necessary to remove the take-up shaft 3, pull the telescopic rod 23 outward to make the telescopic rod 23 move out of position, release the take-up shaft 3, and make it easy to remove the take-up shaft 3.

[0016] This utility model uses a spring to drive the telescopic rod 23 to move toward the paper take-up shaft 3, so as to press and fix the paper take-up shaft 3, which effectively improves the disassembly and assembly efficiency of the paper take-up shaft 3 and facilitates the disassembly and assembly work. At the same time, it effectively improves the efficiency of printing drawings and reduces the time required to replace the corresponding paper take-up shaft 3 after each printing and cutting of the drawings.

[0017] In some embodiments, please refer to Figure 3 The telescopic rod 23 includes a guide end 231, a limiting end 232, and a fixed end 233. The guide end 231 passes through the U-shaped bracket 22, and the fixed end 233 passes through the mounting plate 21 and contacts the end of the take-up shaft 3. One side of the limiting end 232 contacts a spring, and the other side is in movable contact with the mounting plate 21. The spring is sleeved on the guide end 231. The limiting end 232 provides a limit during the telescopic movement of the telescopic rod 23, preventing excessive movement of the telescopic rod 23 and causing it to loosen from the mounting plate 21 or the U-shaped bracket 22, thus ensuring the stability of the overall structure. At the same time, the limiting end 232 provides a force-applying plane for the spring, satisfying the requirement of the spring pushing the telescopic rod 23 towards the take-up shaft 3.

[0018] In some embodiments, the end of the telescopic rod 23 facing the take-up shaft 3 is a conical structure 234, and the take-up shaft 3 is provided with a positioning hole corresponding to the conical structure 234, the conical structure 234 being movably embedded in the positioning hole. When the telescopic rod 23 moves towards the take-up shaft 3 under the elastic force of the spring, the positioning hole is guided and positioned by the conical structure 234, thereby moving the take-up shaft 3 to a position where the positioning hole and the center line of the conical structure 234 are collinear. This ensures that when the take-up shaft 3 is fixed and clamped, both ends of the take-up shaft 3 remain horizontal, avoiding the impact on the paper winding effect due to the tilt of the take-up shaft 3 during paper winding, or the damage to the paper due to uneven force on both sides.

[0019] In some embodiments, a U-shaped seat 24 is provided on the side of the mounting plate 21 facing the take-up shaft 3, and the end of the take-up shaft 3 is placed on the U-shaped seat 24. By placing both ends of the take-up shaft 3 on the U-shaped seat 24 respectively, support can be directly provided for the take-up shaft 3 before the telescopic rod 23 is pressed against it, thus providing a foolproof effect for the installation and removal of the take-up shaft 3.

[0020] In some embodiments, a drive mechanism 25 is provided on the mounting plate 21 at the end without the U-shaped bracket 22, and the output end of the drive mechanism 25 is in movable contact with the take-up shaft 3. In some optional embodiments, the drive mechanism 25 is a motor, and a reducer is connected to the output end of the motor. The reducer adjusts the output of the motor to reduce speed and increases the output torque, thereby satisfying the drive of the take-up shaft 3, allowing the take-up shaft 3 to rotate and realize the traction and winding of the drawing.

[0021] In summary, this utility model uses a spring to drive the telescopic rod to move towards the paper take-up shaft, so as to press and fix the paper take-up shaft, which effectively improves the disassembly and assembly efficiency of the paper take-up shaft and facilitates the disassembly and assembly work. At the same time, it effectively improves the efficiency of printing drawings and reduces the time required to replace the corresponding paper take-up shaft after each printing and cutting of the drawings.

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
