Description

Technical Field

[0001] This utility model relates to the field of wire marking machine technology, specifically to a carbon ribbon box. Background Technology

[0002] A ribbon marking machine is a device specifically designed for printing identification labels. It uses a ribbon (similar to the ribbon used in barcode printers) to print text, numbers, and symbols. Ribbon marking machines provide clear and durable marking solutions for various electrical installations, industrial automation, and mechanical equipment.

[0003] 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. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a carbon ribbon box that solves the problem that the damping force value of the carbon ribbon roll in the existing line marking machine changes when it is in a full roll or small roll state, which easily affects the stable delivery of carbon ribbon.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0012] 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 carbon ribbon can pass through the receiving space by bypassing the third guide post and pass through the receiving space by bypassing the fourth guide post. The housing has a printing port with a hollow area formed between the third guide post and the fourth guide post.

[0013] 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.

[0014] 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.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0028] To address the technical problem that the damping force of the damping module in the existing wire marking machine is inconvenient to adjust, this utility model provides a damping mechanism for carbon ribbon in a wire marking machine, ensuring stable dispensing of carbon ribbon rolls whether they are fully wound or in small rolls.

[0029] Please see Figures 1-6 , Figures 1-6 An embodiment of the present invention provides a mounting base comprising a housing 1, a first guide post 2, a dispensing roll 3, a retracting roll 4, and a damping spring 5. The housing 1 has an accommodating space. The first guide post 2 is disposed within the accommodating space. The dispensing roll 3 and the retracting roll 4 are disposed within the accommodating space and rotatably connected to the housing 1. The damping spring 5 is disposed within the accommodating 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.

[0030] It should be noted that, in order to avoid the end of the damping spring scraping off the carbon powder on the carbon ribbon, or even causing the carbon ribbon to tear, the second guide post 6 is specifically 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.

[0031] In this specific 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.

[0032] Based on the above scheme, in order to ensure that a printing port is formed on one side of the housing 1, specifically, 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.

[0033] It should be noted that the carbon ribbon that passes around the second guide post 6 also passes around the third guide post 7 and the fourth guide post 8 in sequence. Specifically, the housing 1 has a printing port with a hollow area between the third guide post 7 and the fourth guide post 8.

[0034] 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.

[0035] 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 specific 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.

[0036] 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 specific embodiment, the thickness of the damping spring 31 is 1mm.

[0037] 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.

[0038] In this specific 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.

[0039] In this specific 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.

[0040] 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.

[0041] Specifically, in order to save costs, the wire marking machines on the market use guide posts inside the ribbon box to transport the ribbon. The guide posts rub directly against the ribbon, and after multiple bends, the friction on the ribbon is relatively large, which is not conducive to ribbon feeding. This solution uses ribbon guide tubes 10 that are rotatably installed on the first guide post 2, the second guide post 6, the third guide post 7 and the fourth guide post 8 to change the sliding friction of the ribbon into rolling friction, which can greatly reduce the frictional resistance on the surface of the ribbon.

[0042] 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.

[0043] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
