Description

Technical Field

[0001] This utility model relates to the technical field of laser engraving machines, and in particular to a heat shrink tubing coding machine. Background Technology

[0002] Laser engraving machines, also known as laser marking machines or laser engraving machines, use a laser beam to carve permanent marks on the surface of materials or inside transparent materials. When a material absorbs the laser beam, a physical or chemical reaction occurs, leaving permanent, high-precision marks, patterns, or text on the material's surface.

[0003] To ensure stable laser engraving on the workpiece surface, a fixture is often installed below the laser to hold the workpiece in place. However, for long, hollow, and flexible materials such as heat shrink tubing, existing fixtures are ineffective at securing them. Specifically, applying excessive clamping force to the heat shrink tubing causes it to collapse and prevents engraving, while insufficient clamping force leads to misalignment and prevents proper engraving. Therefore, this application proposes a heat shrink tubing engraving machine to achieve engraving on the surface of heat shrink tubing. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a heat shrink tubing coding machine that reliably fixes the heat shrink tubing for laser engraving on its surface.

[0007] A machine base, wherein a laser is mounted on the machine base; and

[0008] The feeding assembly includes a loading platform, a feeding roll, a feeding drive, and two roller assemblies. The loading platform is mounted on the machine base and located below the laser. The loading platform has a material groove adapted to the heat shrink tubing. The two roller assemblies are rotatably mounted at both ends of the loading platform. Each roller assembly includes a drive wheel and a driven wheel. The drive wheel has a first annular groove, and the driven wheel has a second annular groove. Both the drive wheel and the driven wheel are rotatably mounted on the loading platform, and the driven wheel abuts against the drive wheel to align the second annular groove with the first annular groove and connect to the material groove. The feeding drive is located below the loading platform, and its output shaft is connected to the drive wheel. The feeding roll is rotatably mounted on one side of the machine base and is used to release the heat shrink tubing so that it passes through the two roller assemblies and slides through the material groove.

[0009] Optionally, multiple material troughs are provided, and the inner diameters of each material trough are different. Multiple first annular grooves and multiple second annular grooves are provided. Each second annular groove is aligned with each first annular groove and connected to each material trough.

[0010] Optionally, the heat shrink tubing coding machine further includes a cutting assembly, which includes a cutting seat, a cutter, and a cutting drive. The cutting seat is disposed on the machine platform and is adjacent to the side of the material carrier away from the unloading roll. The cutter is slidably disposed on the cutting seat. The cutting drive is disposed on the cutting seat and the output shaft of the cutting drive is connected to the cutter. The cutting drive is used to drive the cutter to cut the heat shrink tubing.

[0011] Optionally, the cutting seat is provided with a guide rod, the guide rod is provided with a stop block, and a slider is slidably provided on the guide rod. The cutter is provided on the slider and faces the stop block, and the heat shrink tubing passes through the stop block and the slider.

[0016] Compared with the prior art, the present invention has at least the following advantages:

[0017] This utility model relates to a heat shrink tubing coding machine, which includes a machine base and a feeding assembly. A laser is mounted on the machine base. The feeding assembly includes a material carrier, a feeding roll, a feeding drive, and two roller sets. The material carrier is positioned on the machine base below the laser and has a material groove adapted to the heat shrink tubing. The two roller sets are rotatably mounted at both ends of the material carrier. Each roller set includes a drive wheel and a driven wheel. The drive wheel has a first annular groove, and the driven wheel has a second annular groove.

[0023] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0024] like Figure 1 and Figure 2 As shown, a heat shrink tubing coding machine 10 includes a machine base 100 and a feeding assembly 200. A laser 300 is mounted on the machine base 100. The feeding assembly 200 includes a loading platform 210, a feeding roll 220, a feeding drive 230, and two roller sets 240. The loading platform 210 is mounted on the machine base 100 and located below the laser 300. A material groove 211 adapted to the heat shrink tubing is provided on the loading platform 210. The two roller sets 240 are rotatably mounted at both ends of the loading platform 210. Each roller set 240 includes a drive wheel 241 and a driven wheel 242. The drive wheel 241 has a first... A first annular groove 2411 is provided, and a second annular groove 2421 is provided on the driven wheel 242. Both the driving wheel 241 and the driven wheel 242 are rotatably mounted on the loading platform 210, and the driven wheel 242 abuts against the driving wheel 241 so that the second annular groove 2421 is aligned with the first annular groove 2411 and connected to the material trough 211. The feeding drive 230 is located below the loading platform 210, and the output shaft of the feeding drive 230 is connected to the driving wheel 241. The unloading roll 220 is rotatably mounted on one side of the machine base 100. The unloading roll 220 is used to release the heat shrink tubing so that the heat shrink tubing passes through the two roller sets 240 and slides through the material trough 211.

[0025] It should be noted that the two roller assemblies 240 are located at both ends of the loading platform 210, and the two roller assemblies 240 are respectively connected to both ends of the material trough 211. Each roller assembly 240 consists of a driving wheel 241 and a driven wheel 242. Both the driving wheel 241 and the driven wheel 242 are mounted on the loading platform 210 via bearings, and the driving wheel 241 and the driven wheel 242 abut against each other. This aligns the first annular groove 2411 on the driving wheel 241 with the second annular groove 2421 on the driven wheel 242. Furthermore, the first annular groove 2411 and the second annular groove 2421 jointly connect to the material trough 211. Thus, the feeding drive 230 drives the two active wheels 241 to rotate, which in turn causes the two passive wheels 242 to rotate as well. This allows the heat shrink tubing to be clamped and moved by the first annular groove 2411 and the second annular groove 2421, so that the heat shrink tubing can slide stably through the material groove 211. This allows the laser 300 located above the material groove 211 to stably laser engrave the heat shrink tubing in the material groove 211.

[0026] In one embodiment, multiple material troughs 211 are provided, and the inner diameters of each material trough 211 are different. Multiple first annular grooves 2411 and multiple second annular grooves 2421 are provided. Each second annular groove 2421 is aligned with each first annular groove 2411 and connected to each material trough 211.

[0027] It should be noted that, in order for the feeding assembly 200 to be used to transport heat shrink tubing of different diameters, so that the laser 300 can laser engrave on heat shrink tubing of different diameters, multiple material slots 211 are formed on the material carrier 210, multiple first annular grooves 2411 are formed on the drive wheel 241, and multiple second annular grooves 2421 are formed on the driven wheel 242. Each second annular groove 2421 is aligned with each first annular groove 2411 and connects to each material slot 211. It is important to note that the inner diameter of each material slot 211 is consistent with the inner diameter of the corresponding connected first annular groove 2411 and second annular groove 2421. In this way, different material slots 211, first annular grooves 2411, and second annular grooves 2421 can be selected according to the different diameters of the heat shrink tubing.

[0028] like Figure 1 and Figure 2 As shown, in one embodiment, the heat shrink tubing coding machine 10 further includes a cutting assembly 400. The cutting assembly 400 includes a cutting seat 410, a cutter 420, and a cutting drive 430. The cutting seat 410 is disposed on the machine base 100 and is adjacent to the side of the material carrier 210 away from the unloading roll 220. The cutter 420 is slidably disposed on the cutting seat 410. The cutting drive 430 is disposed on the cutting seat 410 and the output shaft of the cutting drive 430 is connected to the cutter 420. The cutting drive 430 is used to drive the cutter 420 to cut the heat shrink tubing.

[0029] It should be noted that after the heat shrink tubing has been laser-engraved, the cutting assembly 400 cuts the long strip of heat shrink tubing into several segments of equal length. Specifically, the cutting seat 410 is located on the side of the loading platform 210 away from the unloading roll 220. The output shaft of the cutting drive 430 drives the cutter 420 to slide back and forth, thereby cutting the laser-engraved heat shrink tubing into several segments of equal length.

[0030] like Figure 1 and Figure 2 As shown, in one embodiment, a guide rod 440 is provided on the cutting seat 410, a stop block 450 is provided on the guide rod 440, a slider 460 is slidably provided on the guide rod 440, a cutter 420 is provided on the slider 460 and the cutter 420 is positioned towards the stop block 450, and a heat shrink tube passes through between the stop block 450 and the slider 460.

[0031] It should be noted that the guide rod 440 is horizontally fixed on the cutting seat 410, the stop block 450 and the guide rod 440 are fixedly installed, the guide rod 440 passes through the slider 460, allowing the slider 460 to slide along the axial direction of the guide rod 440, and the cutter 420 is fixedly installed on the slider 460. Thus, when the heat shrink tubing is passed between the slider 460 and the stop block 450, and the cutting drive 430 drives the slider 460 closer to the stop block 450, the cutter 420 can cut the heat shrink tubing. In one embodiment, the stop block 450 has a clearance groove to prevent the cutter 420 from passing through. Thus, when the slider 460 drives the cutter 420 into the clearance groove, it ensures that the cutter 420 cuts the heat shrink tubing.

[0032] like Figure 2 As shown, in one embodiment, the cutting drive 430 includes a cutting motor 431 and a cam 432. The cutting motor 431 is disposed on the cutting seat 410, and the cam 432 is disposed on the output shaft of the cutting motor 431, and the cam 432 is connected to the slider 460.

[0033] It should be noted that the cutting motor 431 drives the cam 432 to rotate, thereby causing the cam 432 to drive the slider 460 to slide back and forth along the guide rod 440. In one embodiment, a spring is sleeved on the guide rod 440, with the two ends of the spring abutting against the slider 460 and the stop block 450 respectively. Thus, when the cam 432 does not push the slider 460, the spring pushes the slider 460, causing the slider 460 to drive the cutter 420 away from the stop block 450.

[0034] In one embodiment, two guide rods 440 are provided, with a gap between them, and the axes of the two guide rods 440 are parallel. Thus, both guide rods 440 pass through the slider 460, causing the slider 460 to drive the cutter 420 to reciprocate relative to the stop block 450.

[0035] like Figure 1 As shown, in one embodiment, the cutting assembly 400 further includes a collection box 470, which is disposed on the machine base 100 and is located on the side of the cutting seat 410 away from the loading table 210.

[0036] Thus, the material collection box 470 is positioned adjacent to the cutter 420. After the cutter 420 cuts the heat shrink tubing, the small section of heat shrink tubing falls directly into the material collection box 470.

[0037] like Figure 1 and Figure 2 As shown, in one embodiment, the feeding drive 230 includes a feeding motor 231 and a belt 232. The feeding motor 231 is disposed on one side of the loading platform 210, and the belt 232 is connected to the drive wheel 241 and the output shaft of the feeding motor 231 respectively.

[0038] It should be noted that pulleys are installed on the output shaft of the feeding motor 231 and the drive wheel 241. The belt 232 is sleeved on the pulleys of the feeding motor 231 and the two drive wheels 241, so that the feeding motor 231 can stably drive the two drive wheels 241 to rotate.

[0039] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood as including, but not limited to, locking and fixing with screws / bolts, welding, or bonding with adhesives, wherein the adhesives used can be commercially available finished products. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
