Abstract
Description
A carbon ribbon box
[0001] This application claims priority to Chinese patent application filed on December 27, 2024, with application number 202423252859.X, entitled "A Carbon Ribbon Box", the entire contents of which are contained herein. Technical Field
[0002] This application relates to the field of wire marking machine technology, specifically to a carbon ribbon box. Background Technology
[0003] A ribbon marking machine is a device specifically configured to print identification labels. It uses ribbon (similar to the ribbon used in barcode printers) to print text, numbers, and symbols. Ribbon marking machines can provide clear and durable marking solutions for various electrical installations, industrial automation, and mechanical equipment.
[0004] Currently, most carbon ribbon marking machines on the market use damping designs on the dispensing shaft, such as adding a damper to the dispensing shaft or using a spring pressure plate in the carbon ribbon box. This affects both material cost control and the complexity of the structural design. In addition, adding damping to the dispensing shaft results in inconsistent damping force values when the carbon ribbon is fully wound and in a small roll. Different damping force values will affect the stable dispensing of the carbon ribbon, causing uneven stress and resulting in wrinkled ribbon.
[0005] Application content
[0006] The purpose of this application is to overcome the above-mentioned technical deficiencies and provide a ribbon box that solves the problem that the damping force value of the ribbon roll in the existing wire gauge machine changes when it is in a full roll or small roll state, which easily affects the stable delivery of the ribbon.
[0007] To achieve the above-mentioned technical objectives, this application adopts the following technical solution:
[0008] This application provides a ribbon cartridge, comprising:
[0009] A housing having an internal receiving space;
[0010] A first guide post is disposed within the accommodating space;
[0011] A dispensing roll and a retractable roll, wherein the dispensing roll and the retractable roll are disposed within the receiving space and rotatably connected to the housing; and
[0012] A damping spring is disposed within the receiving space. One end of the damping spring is connected to the housing, and the damping spring extends beyond the first guide post and constantly applies a clamping force to the first guide post. A carbon ribbon is sandwiched between the damping spring and the first guide post.
[0013] In some embodiments, a second guide post is further included, which is disposed within the receiving space and located below one side of the first guide post, and the carbon ribbon can bypass the first guide post and extend from below to the second guide post.
[0014] In some embodiments, a third guide post and a fourth guide post are further included. The third guide post and the fourth guide post are spaced apart within the receiving space and located above one side of the first guide post.

The housing has a printing port with a hollow area formed between the third guide post and the fourth guide post.
[0015] In some embodiments, a protective layer is provided on one side of the damping spring, and the protective layer is in contact with the carbon ribbon.
[0016] In some embodiments, a mounting base is further included, the mounting base being fixed within the housing, and the damping spring is detachably connected to the mounting base.
[0017] In some embodiments, the mounting base includes a base body and a locking member. The base body is fixed within the housing. The locking member has a first state in which it surrounds the base body to form a limiting hole. The locking member also has a second state in which the limiting hole is opened to form an opening. In the first state, the damping spring can be fixed within the limiting hole. In the second state, the damping spring can move into / out of the limiting hole through the opening.
[0018] In some embodiments, the locking member is detachably connected to the base.
[0019] In some embodiments, the seat body is provided with a groove, and the locking member includes a cover plate and a limiting block connected to the cover plate.

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0031] To address the technical problem that the damping force of the damping module in the existing wire marking machine is inconvenient to adjust, this application provides a damping mechanism for carbon ribbon in a wire marking machine, which ensures stable feeding of carbon ribbon rolls whether they are fully wound or in small rolls.
[0032] Please refer to Figures 1-6. Figures 1-6 show a carbon ribbon cartridge according to an embodiment of this application, including a housing 1, a first guide post 2, a delivery roll 3, a take-up roll 4, and a damping spring 5. The housing 1 has a receiving space, the first guide post 2 is disposed in the receiving space, the delivery roll 3 and the take-up roll 4 are disposed in the receiving space and rotatably connected to the housing 1, the damping spring 5 is disposed in the receiving space, one end of the damping spring 5 is connected to the housing 1, and the damping spring 5 extends beyond the first guide post 2 and constantly applies a pressing force to the first guide post 2. A carbon ribbon is sandwiched between the damping spring 5 and the first guide post 2.
[0033] It should be noted that, in order to prevent the end of the damping spring from scraping off the carbon powder on the carbon ribbon, or even causing the carbon ribbon to tear, the second guide post 6 is located in the receiving space and below the first guide post 2. The carbon ribbon can bypass the first guide post 2 and extend from below to the second guide post 6.
[0034] In this embodiment, after the carbon ribbon is output from the release roll 3, it first passes around the first guide post 2, and the damping spring 5 presses the carbon ribbon. Then, the carbon ribbon extends downward and passes around the second guide post 6, so that the carbon ribbon and the end of the damping spring form an angle, avoiding contact between the carbon ribbon and the end of the damping spring.
[0035] Based on the above scheme, in order to ensure that a printing port is formed on one side of the housing 1, the third guide post 7 and the fourth guide post 8 are spaced apart in the receiving space and located above the first guide post 2. The carbon ribbon can bypass the third guide post 7 to pass out of the receiving space and bypass the fourth guide post 8 to pass into the receiving space.
[0036] It should be noted that the carbon ribbon that passes over the second guide post 6 also passes over the third guide post 7 and the fourth guide post 8 in sequence, and the housing 1 has a printing port with a hollow area between the third guide post 7 and the fourth guide post 8.
[0037] The housing 1 is further provided with at least one fifth guide post, which is located between the fourth guide post 8 and the recycling roll 4.
[0038] Based on the above solution, in order to avoid scratching the carbon powder on the carbon ribbon, a protective layer 51 is provided on one side of the damping spring 5, and the protective layer 51 is in contact with the carbon ribbon; in this embodiment, the protective layer 51 is a velvet layer, and the velvet layer 32 plays the role of protecting the carbon powder on the surface of the carbon ribbon and preventing scratching.
[0039] Furthermore, the damping force after deformation of the damping spring is controlled by setting the thickness of the damping spring, thereby outputting a constant downward damping force to the carbon belt. The thickness of the damping spring is 0.8-1.2mm. In this embodiment, the thickness of the damping spring 31 is 1mm.
[0040] Based on the above scheme, in order to facilitate the replacement of the damping spring, a mounting base is also included. The mounting base is fixed inside the housing 1, and the damping spring 5 is detachably connected to the mounting base.
[0041] In this embodiment, the mounting base includes a base body 91 and a locking member 92. The base body 91 is fixed inside the housing 1. The locking member 92 has a first state in which it surrounds the base body 91 to form a limiting hole. The locking member 92 also has a second state in which the limiting hole is opened to form an opening. In the first state, the damping spring 5 can be fixed inside the limiting hole. In the second state, the damping spring 5 can move into / out of the limiting hole through the opening.
[0042] In this embodiment, the locking member 92 is detachably connected to the seat 91; wherein, the seat 91 is provided with a groove 911, and the locking member 92 includes a cover plate 921 and a limiting block 922 connected to the cover plate 921. When the cover plate 921 and the seat 91 are closed to form a limiting hole in the first state, the limiting block 922 extends into the groove 911 to press the damping spring 5.
[0043] Based on the above scheme, the seat 91 is provided with at least one protrusion 912, and the cover plate 921 is provided with at least one slot 920 that is inserted into the protrusion 912; wherein, the cover plate 921 and the limiting block 922 are both made of elastic plastic material. When a thicker damping spring is replaced, the limiting block 922 deforms when it squeezes the damping spring, ensuring that the damping spring 31 can be pressed tightly.
[0044] Because commercially available wire marking machines use guide posts inside the ribbon box to transport the ribbon in order to save costs, the guide posts rub directly against the ribbon. After multiple bends, the friction on the ribbon is relatively large, which is not conducive to ribbon feeding. This solution converts the sliding friction of the ribbon into rolling friction by rotating ribbon guide tubes 10 on the first guide post 2, the second guide post 6, the third guide post 7 and the fourth guide post 8, which can greatly reduce the frictional resistance on the surface of the ribbon.
[0045] It should be noted that by setting the first guide post 2, the second guide post 6, the third guide post 7 and the fourth guide post 8 on the ribbon conveying channel to change the turning direction of the ribbon, the flattening ability of the ribbon can be improved, so that the ribbon can be dispensed and recycled more smoothly and stably during the printing process.
[0046] The embodiments described above do not constitute a limitation on the scope of protection of this application. Any other corresponding changes and modifications made based on the technical concept of this application should be included within the scope of protection of the claims of this application.
