Description

TECHNICAL FIELD

[0001] The utility model relates to a line marking machine technical field, specifically related to a line marking machine carbon ribbon waste ribbon recovery structure. BACKGROUND

[0002] The carbon ribbon line marking machine is a specific type of line marking machine that uses carbon ribbon (similar to the carbon ribbon in a bar code printer) to print cable labels. The working principle of this machine is to transfer the printed content (such as numbers, letters or other symbols) from the carbon ribbon to the label material through thermal transfer technology.

[0003] The line marking machines on the market currently use conventional spool design for cost saving, and do not have anti-reverse structure. The printed waste ribbon may also be reversed to the dispensing end, which may cause missing or disordered printing content in the next printing, affecting the normal operation of the line marking machine. Therefore, there is an urgent need to design a line marking machine carbon ribbon waste ribbon recovery structure to prevent waste ribbon recovery caused by reverse rotation of the carbon ribbon dispensing end. UTILITY MODEL CONTENT

[0004] The utility model aims to overcome the above technical deficiencies and provide a line marking machine carbon ribbon waste ribbon recovery structure to solve the problem of missing or disordered printing content in the next printing caused by the printed waste ribbon being reversed to the dispensing end during the dispensing process of the carbon ribbon of the line marking machine.

[0005] To achieve the above technical purpose, the utility model adopts the following technical scheme:

[0006] The utility model provides a line marking machine carbon ribbon waste ribbon recovery structure, which comprises a carbon ribbon box, a carbon ribbon dispensing piece, a carbon ribbon winding piece and a recovery prevention piece. The carbon ribbon box comprises a bottom shell and a top shell, and two through holes are formed in the bottom shell. The carbon ribbon dispensing piece and the carbon ribbon winding piece are rotatably arranged between the bottom shell and the top shell. The carbon ribbon dispensing piece comprises a dispensing carbon ribbon shaft, which is provided with a mounting hole along the axial direction. The dispensing carbon ribbon shaft is rotatably arranged between the bottom shell and the top shell, and the mounting hole corresponds to one of the through holes.

[0007] The recovery prevention piece comprises an elastic piece and a dispensing ribbon shaft ratchet. The dispensing ribbon shaft ratchet and the elastic piece are arranged in the mounting hole, and the elastic piece is connected between the dispensing ribbon shaft ratchet and the top shell. The dispensing ribbon shaft ratchet is used to limit the reverse rotation of the dispensing carbon ribbon shaft, and the restriction can be removed by driving the dispensing ribbon shaft ratchet to press the elastic piece.

[0008] In one embodiment, a plurality of limiting blocks are arranged circumferentially in the mounting hole, and each of the limiting blocks has a first ratchet-shaped protrusion at its end near the top shell. The dispensing belt ratchet has at least one pawl at its end near the top shell, and the pawl can slide in contact with each of the first ratchet-shaped protrusions.

[0009] In one embodiment, the ends of the plurality of limiting blocks near the bottom shell are provided with second ratchet-shaped protrusions, and the plurality of second ratchet-shaped protrusions are oriented in the opposite direction to the plurality of first ratchet-shaped protrusions.

[0010] In one embodiment, the dispensing belt ratchet is cylindrical in shape, and an annular block is provided at one end of the dispensing belt ratchet near the top shell, and the pawls are all located on the lower end face of the annular block.

[0011] In one embodiment, a limiting groove is formed in the middle of the dispensing ratchet near one end of the top shell, one end of the elastic member is fixedly connected to the top shell, and the other end of the elastic member is fixedly connected to the inner bottom wall of the limiting groove.

[0012] In one embodiment, a limiting rod is provided in the limiting groove, a sliding groove is provided in the limiting rod, a guide rod is fixed on the top shell and slides with the sliding groove, and the elastic element is sleeved on the limiting rod and the guide rod.

[0013] In one embodiment, the other end of the dispensing ratchet with shaft is fixed to a protrusion.

[0014] In one embodiment, the carbon ribbon take-up component includes a carbon ribbon recovery shaft with a through hole along its axial direction. The carbon ribbon recovery shaft rotates between the bottom shell and the top shell, and the through hole corresponds to another perforation.

[0015] In one embodiment, the through hole is provided with a plurality of mounting blocks spaced apart circumferentially, and each mounting block is provided with a third ratchet-shaped protrusion at one end near the bottom shell.

[0016] In one embodiment, a plurality of mounting posts are fixedly provided on the top shell, and the plurality of mounting posts are all located on the ribbon transport channel between the ribbon dispenser and the ribbon rewinder, and each of the mounting posts is rotatably provided with a sleeve.

[0017] Compared with the prior art, the present invention provides a waste ribbon recycling structure for a wire marking machine. The structure features a ribbon dispensing shaft with mounting holes along its axial direction. The dispensing shaft rotates between a bottom shell and a top shell, and the mounting holes correspond to a through hole on the bottom shell. A ratchet and an elastic element are both located within the mounting holes, with the elastic element connecting the ratchet and the top shell. The ratchet restricts the reverse rotation of the ribbon dispensing shaft, and the restriction is released when the ratchet is pressed against the elastic element. When the ribbon cartridge is not installed on the wire marking machine, the ratchet restricts the reverse rotation of the ribbon dispensing shaft, preventing it from reversing and ensuring that the printed waste ribbon does not return to the dispensing shaft. The structure is simple and reliable, guaranteeing the accuracy of the printed content. Attached Figure Description

[0024] 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.

[0025] To address the technical problem in existing wire marking machines where used ribbon may return to the dispensing end during the ribbon dispensing process, potentially causing missing or incorrect content in subsequent prints, this invention provides a wire marking machine ribbon anti-waste ribbon recycling structure. This structure can lock the ribbon dispensing component when ribbon dispensing stops, preventing the ribbon dispensing shaft from reversing.

[0026] Please see Figures 1-6, Figures 1-6 This utility model discloses a structure for preventing waste tape recycling of carbon ribbon in a wire marking machine, comprising a carbon ribbon box 1, a carbon ribbon dispensing component 2, a carbon ribbon winding component 3, and an anti-recycling component 4. The carbon ribbon box 1 includes a bottom shell 11 and a top shell 12, with two through holes 111 on the bottom shell 11. The carbon ribbon dispensing component 2 and the carbon ribbon winding component 3 are rotatably disposed between the bottom shell 11 and the top shell 12. The carbon ribbon dispensing component 2 includes a carbon ribbon dispensing shaft 21, which has mounting holes 211 along its axial direction. 1. Rotates between the bottom shell 11 and the top shell 12, and the mounting hole 211 corresponds to a through hole 111; the anti-recycling component 4 includes an elastic element 41 and a dispensing belt shaft ratchet 42. The dispensing belt shaft ratchet 42 and the elastic element 41 are both disposed in the mounting hole 211, and the elastic element 41 is connected between the dispensing belt shaft ratchet 42 and the top shell 12. The dispensing belt shaft ratchet 42 is used to restrict the reverse rotation of the dispensing carbon belt shaft 21, and the restriction can be released by driving the dispensing belt shaft ratchet 42 to squeeze the elastic element 41.

[0027] In this specific embodiment, a plurality of limiting blocks 212 are arranged circumferentially within the mounting hole 211, and each of the limiting blocks 212 has a first ratchet-shaped protrusion 2121 near the end of the top shell 12. The dispensing belt ratchet 42 has at least one pawl 421 near the end of the top shell 12, and the pawl 421 can slide in contact with each of the first ratchet-shaped protrusions 2121 respectively.

[0028] It should be noted that when the carbon ribbon box 1 is not installed on the wire marking machine (not shown in the figure), the feeder shaft ratchet 42 is affected by the pressure of the elastic element 41, and the pawl 421 on the feeder shaft ratchet 42 inserts between two adjacent limit blocks 212. At this time, the feeder shaft 21 can only rotate in the direction of the helical teeth (i.e., the carbon ribbon feeding direction). When it reverses, the first ratchet-shaped protrusion 2121 on the feeder shaft can abut against the pawl 421, thereby preventing the waste tape from reversing onto the feeder shaft.

[0029] In addition, when the ribbon cartridge 1 is installed on the wire marking machine, the ribbon dispensing shaft rivet on the wire marking machine pushes up the ribbon dispensing shaft ratchet 42, causing the pawl 421 on the ribbon dispensing shaft ratchet 42 to lift up and not be able to contact the first ratchet tooth protrusion 2121 on the ribbon dispensing shaft 21, thus realizing the normal ribbon dispensing function.

[0030] In this specific embodiment, the dispensing belt ratchet 42 is cylindrical in shape, and an annular block 422 is provided at one end of the dispensing belt ratchet 42 near the top shell 12, and the pawls 421 are all provided on the lower end face of the annular block 422.

[0031] In this specific embodiment, a limiting groove 42a is formed in the middle of the dispensing ratchet 42 near one end of the top shell 12. One end of the elastic member 41 is fixedly connected to the top shell 12, and the other end of the elastic member 41 is fixedly connected to the inner bottom wall of the limiting groove 42a. In addition, a limiting rod 42b is provided in the limiting groove 42a, and a sliding groove 42c is formed in the limiting rod 42b. A guide rod 42d that slides with the sliding groove is fixed on the top shell 12, and the elastic member 41 is sleeved on the limiting rod 42b and the guide rod 42d.

[0032] It should be noted that the limiting groove 42a is also provided with a plurality of reinforcing ribs connected to the limiting rod 42b. The limiting rod 42b is slidably connected to the guide rod 42d, which can improve the stability of the dispensing belt shaft ratchet 42 when sliding in the mounting hole 211.

[0033] In addition, a protrusion 423 is fixed at the other end of the feed belt ratchet 42, and the protrusion 423 is cylindrical in shape. The inner diameter of the protrusion 423 is smaller than the inner diameter of the feed belt ratchet 42. When the carbon ribbon box 1 is installed on the wire marking machine, the carbon ribbon feed shaft riveting shaft on the wire marking machine abuts against the protrusion 423.

[0034] It should be noted that the design of the ribbon cartridge dispensing and retrieving shafts in the wire marking machines currently on the market is relatively simple, using a conventional rack and pinion structure to rotate the dispensing and retrieving shafts on the wire marking machine. Because the conventional rack and pinion structure can cause the shaft teeth on the wire marking machine to collide and jam with the shaft teeth inside the ribbon cartridge when installing the ribbon cartridge, the ribbon cartridge needs to be rotated before it can be properly inserted into the wire marking machine.

[0035] In this specific embodiment, the carbon ribbon take-up component 3 includes a carbon ribbon recovery shaft 31. The carbon ribbon recovery shaft 31 has a through hole 311 along its axial direction. The carbon ribbon recovery shaft 31 rotates between the bottom shell 11 and the top shell 12, and the through hole 311 corresponds to another through hole 111. The through hole 311 is provided with a plurality of mounting blocks 312 spaced apart circumferentially. Each mounting block 312 has a third ratchet-shaped protrusion 313 at one end near the bottom shell 11. The ends of the plurality of limiting blocks 212 near the bottom shell 11 are provided with second ratchet-shaped protrusions 2122. The direction of the plurality of second ratchet-shaped protrusions 2122 is opposite to that of the plurality of first ratchet-shaped protrusions 2121, while the direction of the plurality of second ratchet-shaped protrusions 2122 is the same as that of the third ratchet-shaped protrusions 313.

[0036] Specifically, by designing the ordinary racks on the ribbon dispenser and ribbon take-up shafts to be helical teeth for insertion, the ribbon dispenser and ribbon take-up shafts can be properly inserted into their positions by sliding in at any angle, which improves the fault tolerance when inserting the ribbon and solves the problem of the ribbon getting stuck.

[0037] Based on the above scheme, a plurality of mounting posts 13 are fixed on the top shell 12. The plurality of mounting posts 13 are all located on the carbon ribbon transmission channel between the carbon ribbon dispensing component 2 and the carbon ribbon rewinding component 3, and each mounting post 13 is rotatably provided with a sleeve.

[0038] Specifically, in order to save costs, wire marking machines on the market have mounting posts inside the ribbon box to wind the ribbon. The mounting 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 changes the sliding friction of the ribbon to rolling friction by rotating the ribbon guide on the mounting post, which greatly reduces the frictional resistance on the ribbon surface.

[0039] In this specific embodiment, the ribbon cartridge 1 is provided with five mounting posts 13, and each mounting post 13 is rotatably provided with a ribbon guide tube. The five mounting posts 13 change the turning direction of the ribbon, which improves the ribbon flattening ability and enables the ribbon to be dispensed and recycled more smoothly and stably during the printing process.

[0040] 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.
