Description

Technical Field

[0001] This utility model relates to the field of string processing technology, and more specifically, to a carbon fiber nylon composite string processing equipment. Background Technology

[0002] There are currently three types of commonly used strings: steel strings, nylon strings, and gut strings. Nylon composite strings, which are the mainstream type of strings, are a type of string that combines different materials to optimize sound quality, durability, and playing experience. They combine the advantages of both gut and steel strings, having a beautiful tone close to that of gut strings, as well as the volume and stability of steel strings, and producing a soft and sweet sound.

[0003] Nylon composite strings are mainly made of carbon fiber bundles and nylon resin. The main processing steps are as follows: the carbon fiber bundles are passed through a nylon resin liquid tank, and the dissolved nylon resin liquid is applied to the surface of the carbon fiber bundles in 5 to 12 times. After each application, the bundles are dried to finally form carbon fiber nylon composite string wire.

[0004] Since carbon fiber bundles are made up of multiple single fibers bundled together, a lubricant is applied to their surface to prevent the single fibers from breaking and wearing due to friction during winding or unwinding. When applying nylon resin liquid, the lubricant on the surface of the carbon fiber bundles will affect the adhesion of the nylon resin liquid, resulting in substandard product quality. Utility Model Content

[0005] The present invention provides a carbon fiber nylon composite string processing equipment, which aims to solve the following problem: In existing carbon fiber nylon composite string processing equipment, the surface of the carbon fiber bundle has a lubricant, which affects the adhesion of the nylon resin liquid when applying the nylon resin liquid.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a carbon fiber nylon composite string processing equipment, including a processing table, a processing mechanism installed on the processing table, the processing mechanism including a cleaning seat, a drying cylinder connected to one side of the cleaning seat, and a coating seat fixedly provided at the end of the drying cylinder away from the cleaning seat; a cleaning chamber is opened inside the cleaning seat, a cleaning head is installed at the top of the cleaning chamber, and a drain outlet is opened at the bottom of the cleaning seat; fins are fixedly provided on the outer periphery of the drying cylinder, and several groups of fins are arranged along the axial direction of the drying cylinder, an air inlet and an air outlet are provided between two groups of adjacent fins, and the air inlet and air outlet are respectively located at the top and bottom of the drying cylinder; a fan assembly is provided above the drying cylinder, and the fan assembly is correspondingly arranged with the fins.

[0007] In a preferred embodiment, the coating seat has a coating cavity inside, and a pressing wheel and a guide wheel are rotatably installed inside the coating cavity. Two sets of guide wheels are arranged opposite each other.

[0009] In a preferred embodiment, a cooling seat is provided on one side of the curing seat, and an air outlet is connected to one end of the cooling seat, with the air outlet corresponding to one side of the outlet head.

[0010] In a preferred embodiment, a linear drive assembly is provided on the side of the curing base away from the cooling base. A detection base is mounted on the linear drive assembly. A detection cavity is opened on one side of the detection base. A detection head is provided inside the detection cavity. Two sets of detection heads are provided corresponding to the bottom and top of the detection base. A pressure sensor is connected to the detection head, and the pressure sensor is fixedly connected to the detection base.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention first cleans and cools the carbon fiber bundles to remove surface impurities, thereby improving the adhesion of subsequent coatings. While improving the cleaning effect of the carbon fiber bundles, it also avoids the surface temperature from affecting the subsequent application of nylon resin liquid, ensuring product quality.

[0016] This invention delivers nylon resin liquid into the coating chamber via a material pump and a liquid guide port. The carbon fiber bundle is immersed in the nylon resin liquid through two sets of triangularly distributed guide wheels and one set of pressing wheels.

[0026] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0027] Refer to the instruction manual appendix Figures 1 to 3A carbon fiber nylon composite string processing device includes a processing table 1, on which a processing mechanism 2 is installed. The processing mechanism 2 includes a cleaning seat 21, one side of which is connected to a drying cylinder 22. A coating seat 24 is fixedly installed at the end of the drying cylinder 22 away from the cleaning seat 21. A cleaning chamber 211 is opened inside the cleaning seat 21, and a cleaning head 212 is installed at the top of the cleaning chamber 211. A drain outlet 213 is opened at the bottom of the cleaning seat 21. Fins 221 are fixedly provided on the outer periphery of the drying cylinder 22, and several groups of fins 221 are arranged along the axial direction of the drying cylinder 22. An air inlet 222 and an air outlet 223 are provided between two groups of adjacent fins 221. The air inlet 222 and the air outlet 223 are respectively located at the top and bottom of the drying cylinder 22. A fan assembly 23 is provided above the drying cylinder 22, and the fan assembly 23 is correspondingly arranged with the fins 221.

[0028] It should be noted that the cleaning head 212 is connected to an external water pump, which provides hot water to the cleaning head 212, and the coating seat 24 contains nylon resin liquid.

[0029] In this embodiment, the specific implementation scenario is as follows: Select a carbon fiber bundle of appropriate specifications. The carbon fiber bundle first enters the cleaning chamber 211 and is rinsed with hot water through the cleaning head 212 to remove the lubricant from the surface of the carbon fiber bundle. The wastewater is discharged through the drain outlet 213. The cleaned carbon fiber bundle enters the drying cylinder 22. Cold air is blown onto the fins 221 by the fan assembly 23. The cold air enters the drying cylinder 22 through the air inlet 222 and is discharged from the air outlet 223 for drying. The fins 221 can quickly reduce the temperature of the carbon fiber bundle after hot water cleaning. The carbon fiber bundle is cleaned and cooled and dried to remove surface impurities, thereby improving the adhesion of the subsequent coating. While improving the cleaning effect of the carbon fiber bundle, the surface temperature is prevented from affecting the subsequent application of nylon resin liquid, ensuring the product quality is qualified.

[0030] Furthermore, the coating seat 24 is provided with a coating cavity 241 inside. Inside the coating cavity 241, a pressing wheel 242 and a guide wheel 243 are rotatably installed, and two sets of guide wheels 243 are arranged opposite each other. One side of the coating seat 24 is fixedly installed on the liquid preparation seat 25, and the liquid preparation seat 25 and the coating cavity 241 are connected through a liquid guide port 251.

[0031] It should be noted that a material pump is installed inside the liquid preparation seat 25. Nylon resin liquid is delivered into the coating chamber 241 through the material pump and the liquid guide port 251. The two sets of guide wheels 243 and the set of pressing wheels 242 are triangularly distributed, which can coat the surface of the carbon fiber bundle with nylon resin liquid to obtain carbon fiber nylon composite string wire.

[0032] Furthermore, a curing mechanism 3 is installed on the processing table 1. The curing mechanism 3 includes a curing seat 31, a heating seat 32 is fixedly provided at the bottom of the curing seat 31, an exhaust port 311 is provided at the top of the curing seat 31, an outlet head 312 is detachably connected to one end of the curing seat 31, and a heating component is installed inside the heating seat 32.

[0033] It should be noted that the carbon fiber nylon composite string wire passes through the curing seat 31, the heating component is an electric heater, and the curing seat 31 and the heating seat 32 are connected to cure the carbon fiber nylon composite string wire.

[0034] In this embodiment, the specific implementation scenario is as follows: Nylon resin liquid is delivered into the coating cavity 241 through the material pump and the liquid guide port 251. The carbon fiber bundle is immersed into the nylon resin liquid through two sets of triangularly distributed guide wheels 243 and a set of pressing wheels 242. Nylon resin liquid is coated on the surface of the carbon fiber bundle to obtain carbon fiber nylon composite string wire. The carbon fiber nylon composite string wire passes through the curing seat 31 and is thermo-cured and molded by the heating component.

[0035] Refer to the instruction manual appendix Figure 4 and Figure 5 A cooling seat 33 is provided on one side of the curing seat 31. One end of the cooling seat 33 is connected to an air outlet 331, and the air outlet 331 is correspondingly located on one side of the outlet head 312.

[0036] It should be noted that an air pump or fan is installed inside the cooling base 33.

[0037] Furthermore, a linear drive assembly 313 is provided on the side of the curing base 31 away from the cooling base 33. A detection base 34 is installed on the linear drive assembly 313. A detection cavity 341 is opened on one side of the detection base 34. A detection head 342 is provided inside the detection cavity 341. Two sets of detection heads 342 are provided corresponding to the bottom and top of the detection base 34. A pressure sensor 343 is connected to the detection head 342, and the pressure sensor 343 is fixedly connected to the detection base 34.

[0038] It should be noted that the pressure sensor 343 includes an outer sleeve and an elastic detection head. The elastic detection head is connected to the detection head 342, and the detection head 342 rolls in close contact with the surface of the carbon fiber nylon composite string material.

[0039] In this embodiment, the specific implementation scenario is as follows: air is blown from the air outlet 331 to the outlet head 312 to cool the cured carbon fiber nylon composite string wire to room temperature, which facilitates the subsequent application of nylon resin liquid. Two sets of detection heads 342 are set up with their upper and lower sides facing each other. The pressure of the corresponding detection head 342 is detected by the pressure sensor 343, and the distance between the two sets of detection heads 342 is calculated. This allows the detection of the diameter of the carbon fiber nylon composite string wire passing between the two sets of detection heads 342. If the detected diameter change is not within the set range, the surface quality of the carbon fiber bundle and the liquid level of the nylon resin liquid inside the coating cavity 241 should be checked.

[0040] Refer to the instruction manual appendix Figures 1 to 3 , Figure 6 and Figure 7 A winding mechanism 4 is installed on the processing table 1, and the winding mechanism 4 is located on the side of the curing mechanism 3 away from the processing mechanism 2. The winding mechanism 4 includes a winding seat 41, and a transition winding chamber 42 is provided inside the winding seat 41. An unwinding port 422 is provided on the top of the transition winding chamber 42.

[0041] It should be noted that the two sets of take-up shafts 421 are respectively connected to drive motors, and the two sets of take-up shafts 421 perform take-up work independently. That is, when one set of take-up shafts 421 is working, the other set of take-up shafts 421 stops working.

[0042] Furthermore, an inlet wheel 27 is installed on the top of the coating seat 24, and the inlet wheel 27 is correspondingly located above the press-in wheel 242. A drive box 26 is installed on the side of the coating seat 24 away from the liquid preparation seat 25.

[0043] It should be noted that a drive motor is installed inside the drive box 26 to drive the guide wheel 27 to rotate.

[0044] Furthermore, both the transition winding chamber 42 and the finished winding chamber 43 are equipped with a winding shaft 421 that rotates inside. The winding seat 41 has a finished winding chamber 43 inside, and the finished winding chamber 43 is located below the transition winding chamber 42. A door panel 431 is hinged to one side of the finished winding chamber 43.

[0045] It should be noted that one side of the finished product winding chamber 43 is open.

[0046] In this embodiment, the specific implementation scenario is as follows: First, the carbon fiber nylon composite string wire is wound into the transition winding chamber 42 through the winding shaft 421. After winding, the carbon fiber nylon composite string wire is unwound onto the guide roller 27 through the unwinding port 422. Secondary coating is performed through the guide roller 27, the pressing roller 242, and the guide roller 243 at the exit. The above steps are repeated until the required number of coatings is reached. Then, the qualified carbon fiber nylon composite string wire is wound into the finished product winding chamber 43. Finally, the door panel 431 is opened to remove the carbon fiber nylon composite string wire from the finished product winding chamber 43. This facilitates multiple coatings and allows for separate winding of the carbon fiber nylon composite string wire before and after coating without the need for re-winding, thus improving processing efficiency.

[0047] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
