Description

Technical Field

[0001] This utility model relates to the technical field of wire marking machine equipment, specifically to a wire marking machine cutter anti-breakage structure. Background Technology

[0002] A wire marking printer, also known as a wire marking machine or wire labeling machine, uses thermal transfer printing technology to print characters on materials such as PVC tubing, heat shrink tubing, and self-adhesive labels. It is generally used for secondary wire marking in electrical control and distribution equipment, and is a dedicated device for marking wiring in electrical control, distribution equipment, and integrated cabling projects. It can meet the needs of power plants, electrical equipment factories, substations, and the power industry for distinguishing and marking wires. It can print on PVC tubing, heat shrink tubing, PET labels, 4mm marking strips, signs, tags, terminal markings, and other materials. Marking is quick and convenient, easily achieving the identification of various cables, pipes, components, and cabinets. Currently, to save costs, many wire marking machines on the market use a plastic part to fix the blade in the cutter holder, and then use a spring to return the blade. The blade has no fixed position or protection. When using a blade without a fixed position structure, there may be uneven force when the cutter pusher pushes the blade, causing the blade to jump out and detach from the cutter holder. In severe cases, the blade may eject and injure the user. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a blade breakage prevention structure for wire marking machine cutters. This solves the technical problem that in the prior art, the cutter blades inside the wire marking machine do not have corresponding limiting structures, which leads to uneven force on the cutter pusher when pushing the blades, causing the blades to break off.

[0004] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0005] Firstly, this utility model provides a chipping prevention structure for a wire marking machine cutter, comprising:

[0006] A blade holder, comprising a top plate and a vertical plate, wherein the vertical plate is connected to one side of the top plate;

[0007] A pressure plate is disposed opposite to the vertical plate and is connected to at least one of the top plate and the vertical plate, forming a tool travel space between the pressure plate and the vertical plate;

[0008] A cutting blade body is disposed in the cutting space and is movably connected to the pressure plate and / or the vertical plate.

[0009] In some embodiments, the anti-breakage structure of the wire marking machine cutter further includes a reset mechanism, which is mounted on the blade holder and used to push the cutter body to reset.

[0010] In some embodiments, the reset mechanism includes a column and a reset torsion spring. The column is connected to at least one of the top plate and the vertical plate, and the reset torsion spring is wound around the column. The two ends of the reset torsion spring are a force-bearing end and a reset end, respectively. One side of the force-bearing end is close to the cutter body, and a gap is maintained between the reset end and the vertical plate.

[0011] In some embodiments, the anti-breakage structure of the wire marking machine cutter further includes a mounting mechanism, and the two ends of the pressure plate are respectively connected to the mounting mechanism.

[0012] In some embodiments, the installation mechanism includes a first limiting block and a second limiting block, the first limiting block and the second limiting block being arranged at both ends of the vertical plate, and the first limiting block and the second limiting block being respectively connected to both ends of the pressure plate.

[0013] In some embodiments, at least one limiting protrusion is formed on the pressure plate, and a limiting ridge is arranged on the vertical plate to cooperate with the limiting protrusion. The tool travel space is formed between the limiting protrusion and the limiting ridge.

[0014] In some embodiments, the number of limiting protrusions and limiting ridges is three, which are respectively formed at the head, middle and tail of the pressure plate, and a strip hole for mounting the cutter body is formed between two adjacent limiting ridges.

[0015] In some embodiments, the blade holder is vertically disposed within the cutter housing, and the cutter housing is provided with a pushing mechanism that extends into the strip hole and can move laterally within the strip hole.

[0016] In some embodiments, the cutter body has a force-receiving groove for the pushing mechanism to push.

[0017] In some embodiments, the length dimension of the top plate is greater than the height dimension of the vertical plate.

[0018] Compared with the prior art, the present invention provides a blade-breakage prevention structure for a wire marking machine cutter. In this application, a combination structure of a blade bracket and a pressure plate is used to limit the cutter body, so that the cutter body can reciprocate within the installation area. The pressure plate effectively restricts the movement space of the cutter body on the vertical plate, preventing blade breakage during use and enhancing product safety and reliability.

[0026] 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 merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] To address the technical problem in existing wire marking machines where the cutter blade lacks a corresponding limiting structure, leading to uneven force on the cutter pusher and causing the blade to break off, this invention provides a wire marking machine cutter anti-breakage structure. This structure incorporates a limiting structure within the blade holder to restrict the cutter body and prevent breakage during use.

[0028] It should be noted that the anti-breakage structure for wire marking machine cutters described in this utility model is used in, but not limited to, the field of wire marking machines. For ease of explanation, this utility model only uses the application of the anti-breakage structure for wire marking machine cutters in the field of wire marking machines as an example. The principle of the anti-breakage structure for wire marking machine cutters applied to other types of equipment is essentially the same as that applied to the field of wire marking machines, and will not be elaborated here.

[0029] Please see Figures 1 to 6 , Figure 1 This is a schematic diagram of the anti-breakage structure of a wire marking machine cutter in one embodiment of the present invention. The anti-breakage structure of the wire marking machine cutter includes a blade support 1, a pressure plate 2, and a cutter body 3. The blade support 1 includes a top plate 11 and a vertical plate 12. The vertical plate 12 is connected to one side of the top plate 11. The pressure plate 2 is disposed opposite to the vertical plate 12. The pressure plate 2 is connected to at least one of the top plate 11 and the vertical plate 12. A cutting space is formed between the pressure plate 2 and the vertical plate 12.

[0030] In this embodiment, the blade holder 1 and the pressure plate 2 are used in combination to limit the movement of the cutter body 3, allowing the cutter body 3 to reciprocate within the installation area. The pressure plate effectively restricts the movement space of the cutter body on the vertical plate, preventing blade breakage during use and enhancing product safety and reliability. Preferably, to facilitate the installation of the pressure plate 2, the pressure plate 2 is connected to the vertical plate.

[0031] In one possible embodiment, the anti-breakage structure of the wire marking machine cutter further includes a reset mechanism 4, which is mounted on the blade support 1 and is used to push the cutter body 3 to reset. Specifically, after the cutter body 3 cuts the wire marking tube, it can be reset by the reset mechanism 4.

[0032] Optionally, the reset mechanism 4 includes a column 41 and a reset torsion spring 42. The column 41 is connected to at least one of the top plate 11 and the vertical plate 12, and the reset torsion spring 42 is wound around the column 41. The two ends of the reset torsion spring 42 are a force-bearing end 421 and a reset end 422, respectively. One side of the force-bearing end 411 is close to the cutter body 3, and the reset end 422 maintains a gap with the vertical plate 12.

[0033] The reset torsion spring 42 is mounted on the column 41, with one end being the force-bearing end 421 and the other end being the reset end 422. During the cutting process, the movement of the cutter body 3 will compress the force-bearing end 421 of the reset torsion spring 42, causing the force-bearing end 421 to deform and the reset end 422 to move towards the vertical plate 12. When the subsequent external pushing mechanism stops pushing the cutter body 3, the force-bearing end 421 of the reset torsion spring 42 pushes the cutter body 3 to move into the vertical plate 12, and the reset end 422 begins to move away from the vertical plate 12, thereby completing the reset action of the cutter body 3.

[0034] In one possible embodiment, the anti-breakage structure of the wire marking machine cutter further includes an installation mechanism. Both ends of the pressure plate 2 are respectively connected to the installation mechanism. By setting the installation mechanism, it can be ensured that the pressure plate 2 can be stably installed on the blade holder 1.

[0035] Optionally, the installation mechanism includes a first limiting block 131 and a second limiting block 132, the first limiting block 131 and the second limiting block 132 are arranged at both ends of the vertical plate 12, and the first limiting block 131 and the second limiting block 132 are respectively connected to both ends of the pressure plate 12.

[0036] In this embodiment, a first limiting block 131 and a second limiting block 132 are arranged from top to bottom on the vertical plate 12, and a pressure plate 2 is set between the first limiting block 131 and the second limiting block 132, so that the pressure plate 2 is stably installed in the installation space formed by the first limiting block 131 and the second limiting block 132, avoiding displacement of the pressure plate 2, thereby ensuring the limiting effect of the pressure plate 2 on the cutter body 3, and further preventing the cutter from breaking.

[0037] In some possible embodiments, at least one limiting protrusion 21 is formed on the pressure plate 2, and a limiting ridge 22 that cooperates with the limiting protrusion 21 is arranged on the vertical plate 12. The cutting space is formed between the limiting protrusion 21 and the limiting ridge 22. Through the limiting effect of the limiting protrusion 21 and the limiting ridge 22, it can be ensured that the cutter body 3 is stably installed in the cutting space and the blade breakage is avoided.

[0038] Optionally, there are three limiting protrusions 21 and three limiting ridges 22, which are formed at the head, middle and tail of the pressure plate 2 respectively. A strip hole 121 for mounting the cutter body 3 is formed between two adjacent limiting ridges 22. Through the limiting effect of the limiting protrusions 21 and limiting ridges 22 at the three positions, it can be ensured that each part of the cutter body 3 is restricted. Moreover, through the limiting effect of the strip hole 121, the cutter body 3 can only move along the strip hole, avoiding misalignment of the cutter body 3.

[0039] In one possible embodiment, the blade holder 1 is vertically disposed inside the cutter housing, and the cutter housing is provided with a pushing mechanism that extends into the strip hole 121 and can move laterally within the strip hole 121. Preferably, the pushing mechanism is a pushing column driven by an external force.

[0040] In one possible embodiment, to facilitate the pushing mechanism to push the cutter body 3, a force-receiving groove 31 is formed on the cutter body 3 for the pushing mechanism to push. The shape of the force-receiving groove 31 is configured to facilitate the pushing mechanism to push the cutter body.

[0041] In one possible embodiment, to further prevent chipping, the length dimension of the top plate 11 is greater than the height dimension of the vertical plate 12.

[0042] In one possible embodiment, the cutter body 3 has a circular hole 32 to facilitate the installation and replacement of the cutter body 3.

[0043] To better understand this utility model, the following is combined with... Figures 1 to 6 The technical solution of this utility model is described in detail below:

[0044] The internal pushing mechanism of the wire marking machine pushes the entire cutter housing, causing the pushing mechanism to move to the left within the slot 121. This, in turn, pushes the cutter blade to the left via the force groove 31, extending it to the outside of the vertical plate 12 and cutting the wire. During the cutting process, the force-bearing end 421 of the return torsion spring 42 is compressed, causing it to deform and its return end 422 to move towards the vertical plate 12. When the subsequent external pushing mechanism stops pushing the cutter housing, the entire pushing mechanism moves to the right within the slot 121. At this point, the return torsion spring 42... The force-bearing end 421 pushes the cutter body 3 to move inward into the vertical plate 12, and the reset end 422 begins to move away from the vertical plate 12. By setting a pressure plate 2 on the vertical plate 12, setting a limiting protrusion 21 on the pressure plate 2, and setting a limiting ridge 22 on the vertical plate 12, the cutter body 3 moves horizontally between the limiting protrusion 21 and the limiting ridge 22. This can prevent the cutter body 3 from breaking during use, thereby effectively enhancing the stability of the entire cutter module, extending its service life, and avoiding accidents during use.

[0045] 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.
