Description

Technical Field

[0001] This application relates to the field of laser printing technology, and in particular to a printing wheel positioning bracket for a laser printing machine. Background Technology

[0002] In the final stage of current cable production, it is necessary to print text on the surface of the formed cable. Currently, this is done using a printing roller. Prior to this, a laser engraving machine is used to laser-engrave the text on the surface of a purchased roller blank, forming a printing roller, which is then used to print the text on the cable surface.

[0003] Currently, the laser printing machines purchased by enterprises are equipped with three-jaw clamps. These clamps hold the shaft and the wheel blank, driving the wheel blank to rotate and laser-engraving the lettering onto it. The disadvantage is that after each installation of the wheel blank on the three-jaw clamp, a lever dial indicator is needed to repeatedly adjust the clamp to ensure that the center line of the printing wheel coincides with the center of the clamp. This adjustment is difficult. When the center lines do not coincide, the three sets of characters on the printing wheel will not be on the same straight line, resulting in intermittent and incomplete printing. This severely affects the engraving pass rate of the printing wheel. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a printing wheel positioning bracket for a laser printer, comprising a fixed bracket and a rotary drive component mounted on the fixed bracket. A rotating block is provided at the drive end of the rotary drive component, and a connecting flange is fixedly mounted on the rotating block. A positioning platform is formed at the center of the connecting flange, and the positioning platform is positioned and engaged with the center hole of the printing wheel. A connecting rod is provided on the positioning platform, and the connecting rod is connected to a locking component for fixing the printing wheel on the positioning platform.

[0005] Preferably, the connecting flange has a boss at the center of its surface away from the rotating block, and the positioning table is disposed on the end face of the boss, the diameter of the positioning table being smaller than that of the boss.

[0006] Preferably, a positioning post is provided at the center of the rotating block, and a positioning hole is provided on the surface of the connecting flange facing the rotating block for the positioning post to pass through. The connecting flange is detachably connected to the rotating block through a connector.

[0007] Preferably, the surface of the connecting rod is threaded, and the locking member is threadedly connected to the connecting rod.

[0008] Preferably, the fixed bracket includes a base and support plates spaced apart on the base, and the rotation drive component is installed between the support plates.

[0009] Preferably, the base has a first waist-shaped groove extending toward the connecting flange.

[0010] Preferably, a second waist-shaped groove extending in the vertical direction is provided on the support plate.

[0011] Preferably, a spring washer is also inserted on the connecting rod, and the spring washer is located between the locking member and the printing wheel.

[0012] As can be seen from the above, the following beneficial effects can be obtained by applying the method provided in this application: By setting a rotating block at the driving end of the rotating drive component, and fixing a connecting flange on the rotating block, a positioning platform is formed at the center of the connecting flange, thereby fixing the fixed bracket on the laser station of the laser printing machine. The printing wheel to be engraved is placed on the positioning platform, and the positioning platform and the center hole of the printing wheel are positioned and matched so that the center of the printing wheel coincides with the rotation center line of the rotating drive component. A connecting rod is set on the positioning platform, and the connecting rod is connected to a locking component for fixing the printing wheel on the positioning platform, thereby fixing the printing wheel on the connecting flange, ensuring that the center of the printing wheel coincides with the rotation center line of the rotating drive component. The installation and operation are convenient and efficient, without the need for repeated adjustments, and the accuracy of the engraving position is improved. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0017] Example

[0018] To address the aforementioned technical problems, this embodiment provides a printing wheel positioning bracket for a laser printer, such as... Figure 1-2 As shown, the device includes a fixed bracket 60 and a rotary drive component 10 mounted on the fixed bracket 60. A rotating block 11 is provided at the driving end of the rotary drive component 10, and a connecting flange 20 is fixedly installed on the rotating block 11. A positioning platform 21 is formed at the center of the connecting flange 20, thereby fixing the fixed bracket 60 on the laser station of the laser printing machine. The printing wheel 30 to be engraved is placed on the positioning platform 21. The positioning platform 21 and the center hole of the printing wheel 30 are positioned and engaged, so that the center of the printing wheel 30 coincides with the rotation center line of the rotary drive component 10. A connecting rod 50 is provided on the positioning platform 21, and the connecting rod 50 is connected to a locking component 40 for fixing the printing wheel 30 on the positioning platform 21, thereby fixing the printing wheel 30 on the connecting flange 20, ensuring that the center of the printing wheel 30 coincides with the rotation center line of the rotary drive component 10. The installation and operation are convenient and efficient, without the need for repeated adjustments, and improve the accuracy of the engraving position.

[0019] Specifically, a boss 22 is provided at the center of the surface of the connecting flange 20 away from the rotating block 11, and a positioning platform 21 is provided on the end face of the boss 22. In some embodiments, the positioning platform 21 and the boss 22 are cylindrical, and the diameter of the positioning platform 21 is smaller than that of the boss 22. After the center hole of the printing wheel 30 passes through the positioning platform 21, the side of the printing wheel 30 abuts against the end face of the boss 22. The positioning platform 21 and the center hole of the printing wheel 30 are positioned and engaged, so that after the printing wheel 30 is installed on the positioning platform 21, the center line of the printing wheel 30 coincides with the center line of the positioning platform 21, thereby ensuring that the rotation center line of the printing wheel 30 coincides with that of the rotating block 11. In some embodiments, the rotary drive 10 is a motor, and the drive end of the motor is connected to the rotating block 11. The rotary drive 10 drives the printing wheel 30 to rotate, and the laser printing machine performs laser engraving on the circumferential surface of the printing wheel 30.

[0020] Furthermore, a positioning post is provided at the center of the rotating block 11, and a positioning hole is opened on the surface of the connecting flange 20 facing the rotating block 11 for the positioning post to pass through. The positioning post and the positioning hole are positioned and engaged, so that the center line of the connecting flange 20 coincides with the center line of the rotating block 11, thereby ensuring that the rotation center line of the printing wheel 30 coincides with that of the rotating block 11. The connecting flange 20 is detachably connected to the rotating block 11 by a connecting member. For example, the connecting member can be a bolt, which is then threaded through the connecting flange 20 and connected to the rotating block 11.

[0021] In the above scheme, the surface of the connecting rod 50 is threaded, and the locking member 40 is threadedly connected to the connecting rod 50. For example, the locking member 40 can be a nut, and the connecting rod 50 can be a screw. After the printing wheel 30 is placed on the positioning table 21, the locking member 40 fixes the printing wheel 30 to the positioning table 21, thereby achieving positioning and installation of the printing wheel 30 and ensuring that the center of the printing wheel 30 coincides with the rotation center. As a preferred embodiment, a spring washer 41 is also placed on the connecting rod 50. The spring washer 41 is located between the locking member 40 and the printing wheel 30. When the locking member 40 is tightened, the spring washer 41 abuts against the printing wheel 30 and the locking member 40. When the locking member 40 is threadedly connected to the connecting rod 50, it prevents the locking member 40 from loosening, which could affect the accuracy of the printing on the printing wheel 30.

[0022] Furthermore, the fixed bracket 60 includes a base 61 and support plates 62 spaced apart on the base 61. The rotation drive 10 is installed between the support plates 62, thereby fixing the base 61 on the laser station of the laser printer. The rotation drive 10 drives the printing wheel 30 to rotate, thereby the laser printer performs laser engraving on the circumferential surface of the printing wheel 30.

[0023] In the above scheme, after the fixed bracket 60 is fixed on the laser station of the laser printer, in order to adjust the position of the fixed bracket 60, a first waist-shaped groove 64 extending toward the connecting flange 20 is provided on the base 61. Then, the base 61 is fixed on the laser printer by passing screws through the waist-shaped groove 64. By adjusting the position of the base 61, the circumferential surface of the printing wheel 30 is located directly below the laser port of the laser printer.

[0024] Furthermore, a second waist-shaped groove 63 extending vertically is provided on the support plate 62, and a screw is inserted through the second waist-shaped groove 63. The rotation drive 10 is fixed between the two support plates 62 by the screw. The height position of the rotation drive 10 can be adjusted through the second waist-shaped groove 63, thereby adjusting the distance between the printing wheel 30 and the laser printing machine and improving the accuracy of laser engraving.

[0025] In summary, the solution of this application provides a rotating block at the drive end of the rotating drive component, a connecting flange fixedly mounted on the rotating block, and a positioning platform formed at the center of the connecting flange. This allows the fixed bracket to be fixed to the laser station of the laser printing machine. The printing wheel to be engraved is placed on the positioning platform, and the positioning platform and the center hole of the printing wheel are aligned to ensure that the center of the printing wheel coincides with the rotation center line of the rotating drive component. A connecting rod is provided on the positioning platform, and the connecting rod is connected to a locking component for fixing the printing wheel on the positioning platform, thereby fixing the printing wheel to the connecting flange. This ensures that the center of the printing wheel coincides with the rotation center line of the rotating drive component. The installation and operation are convenient and efficient, eliminating the need for repeated adjustments and improving the accuracy of the engraving position.

[0026] The embodiments described above do not constitute a limitation on the scope of protection of this technical solution. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the above embodiments should be included within the scope of protection of this technical solution.
