Technical Field

[0001] This utility model belongs to the technical field of large circular knitting machines, specifically relating to a lint removal device suitable for circular knitting machines. Background Technology

[0002] Circular knitting machines, also known as circular weft knitting machines, offer numerous advantages in textiles, such as multiple yarn feed paths, high speed, high output, rapid pattern changes, and high fabric quality. Consequently, their development has been rapid, and their application in the textile industry is widespread. During operation, after the yarn enters the yarn feed assembly, lint from the yarn remains on the assembly. If not handled promptly, this lint will accumulate into clumps over time, potentially falling into the knitting roll and causing fabric defects, thus affecting the quality of the finished roll. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a lint removal device suitable for circular knitting machines with good lint removal effect.

[0004] The present invention adopts the following technical solution:

[0005] A lint removal device suitable for circular knitting machines is provided for removing lint from the machines. The circular knitting machine includes multiple yarn feeding assemblies. The device is characterized by comprising a mounting bracket, multiple cleaning fans, and a power supply mechanism. The mounting bracket is mounted on the circular knitting machine and includes a fixed ring connected to the machine and located above the multiple yarn feeding assemblies, a rotating gear ring rotatably mounted on the outer periphery of the fixed ring, and a drive assembly mounted on the fixed ring and connected to and driving the rotating gear ring to rotate. The multiple cleaning fans are spaced apart on the rotating gear ring, with their blowing ends facing the multiple yarn feeding assemblies. The power supply mechanism is mounted on the mounting bracket and includes a conductive ring mounted on the fixed ring and connected to an external power source, and a power-collecting carbon brush mounted on the rotating gear ring and electrically connected to the multiple cleaning fans via wires. The power-collecting carbon brush is in contact with the conductive ring, and the carbon brush remains in contact with the conductive ring throughout the rotation of the rotating gear ring.

[0006] Furthermore, the power-collecting carbon brush includes a base disposed on the top of the rotating toothed ring, a positive carbon brush and a negative carbon brush disposed on the base, and two wire connection ports disposed on the top of the base corresponding to the positive carbon brush and the negative carbon brush, respectively.

[0007] Furthermore, the conductive ring includes a positive conductive ring and a negative conductive ring spaced apart on the top of the fixed ring. The positive carbon brush contacts and conducts electricity with the positive conductive ring, and the negative carbon brush contacts and conducts electricity with the negative conductive ring.

[0008] Furthermore, the drive assembly includes a fixed base connected to the fixed ring, a drive motor mounted on the fixed base, and a transmission gear mounted at the output end of the drive motor, wherein the transmission gear meshes with the outer circumference of the rotating gear ring.

[0009] Furthermore, the fixing seat includes a connecting portion extending from the bottom of the fixing ring toward the rotating gear ring, a mounting portion extending upward from the top surface of the connecting portion, and a mounting groove extending inward from the mounting portion opposite to the rotating gear ring.

[0010] Furthermore, the drive motor is mounted on the top surface of the mounting part, and the transmission gear is located in the mounting groove.

[0011] Furthermore, the cleaning fan includes a fan mounting base disposed on the top of the rotating gear ring, a fan body, and an adjustable bracket with one end detachably connected to the fan mounting base and the other end connected to the fan body.

[0012] Furthermore, the mounting bracket is composed of multiple splicing brackets, which can be spliced ​​together on the outer periphery of the circular machine.

[0013] As can be seen from the above description of this utility model, compared with the prior art, the beneficial effects of this utility model are as follows: This application, through the cooperation between the mounting bracket set on the circular knitting machine, multiple cleaning fans spaced apart on the top of the rotating gear ring, and the power-taking mechanism set on the mounting bracket, and defining the specific structure of the mounting bracket, allows lint to remain on the yarn feeding assembly after the yarn passes through it. At this time, the drive assembly can drive the rotating gear ring and the multiple cleaning fans on the rotating gear ring to rotate, so that the multiple cleaning fans evenly blow air onto the multiple yarn feeding assemblies on the circular knitting machine, and each yarn feeding assembly can be affected by each cleaning fan. With the same airflow, it can promptly remove lint from multiple yarn feeding components, preventing lint from accumulating and falling into the woven fabric roll, thus improving the lint removal effect and improving the quality of the fabric roll. At the same time, by limiting the specific structure of the power-taking mechanism and setting a conductive ring and a power-taking carbon brush, the wires of multiple cleaning fans can be connected to the same power-taking carbon brush. During the rotation of the rotating gear ring, the power-taking carbon brush rotates with the rotating gear ring and multiple cleaning fans and always maintains contact with the conductive ring. Furthermore, the positions of the wires of multiple cleaning fans and the power-taking carbon brush are relatively fixed, preventing tangling. The wire layout is reasonable and facilitates subsequent maintenance. Attached Figure Description

[0019] The present invention will be further described below through specific embodiments.

[0020] like Figures 1 to 4 As shown, this embodiment provides a lint removal device suitable for circular knitting machines, which is detachably installed on the circular knitting machine for removing lint from the machine. It includes a mounting bracket 1, multiple cleaning fans 2, and a power supply mechanism 3; the circular knitting machine 4 includes multiple yarn feeding assemblies 41.

[0021] Mounting bracket 1, mounted on circular knitting machine 4, includes a fixed ring 11 connected to the circular knitting machine and located above multiple yarn feeding assemblies 41, a rotating gear ring 12 rotatably mounted on the outer periphery of the fixed ring 11, and a drive assembly 13 mounted on the fixed ring 11 and connected to and driving the rotating gear ring 12 to rotate. Multiple cleaning fans 2 are spaced apart on top of the rotating gear ring 12, with the blowing ends of the cleaning fans 2 facing the multiple yarn feeding assemblies 41. When the circular knitting machine 4 is operating, as the yarn passes through the yarn feeding assemblies 41, lint from the yarn remains on the yarn feeding assemblies 41. The drive assembly 13 can drive the rotating gear ring 12 and the multiple cleaning fans 2 to rotate above the yarn feeding assemblies 41, so that the multiple cleaning fans 2 evenly clean the multiple yarn feeding assemblies 41 on the circular knitting machine 4. The system blows air, and each yarn feeding assembly 41 receives the same airflow from each cleaning fan 2, which can promptly remove lint from multiple yarn feeding assemblies 41, preventing lint from accumulating and falling into the woven fabric roll, thus improving the lint removal effect and improving the quality of the fabric roll. Specifically, the drive assembly 13 includes a fixed base 14 connected to the fixed ring 11, a drive motor 15 mounted on the fixed base 14, and a transmission gear 16 mounted on the output end of the drive motor 15. The transmission gear 16 meshes with the outer circumference of the rotating gear ring 12. Furthermore, the fixed base 14 includes a connecting portion 17 extending from the bottom of the fixed ring 11 toward the rotating gear ring 12, and a mounting bracket extending upwards vertically from the top surface of the connecting portion 17. The mounting part 18 and the mounting groove 19 extending inward from the mounting part 18 opposite to the rotating gear ring 12 are included; wherein, the drive motor 15 is disposed on the top surface of the mounting part 18, and the transmission gear 16 is located in the mounting groove 19; further, the mounting bracket 1 is composed of multiple splicing brackets, which can be spliced ​​together on the outer periphery of the circular knitting machine 4; wherein, setting the mounting bracket 1 as a multi-segment splicing structure is beneficial for installing the lint cleaning device on the circular knitting machine 4; further, the cleaning fan 2 includes a fan mounting base 21 disposed on the top of the rotating gear ring 12, a fan body 22, and an adjustable bracket 23 with one end detachably connected to the fan mounting base 21 and the other end connected to the fan body 22; wherein, the adjustable bracket 23 is similar to that in the prior art The structure and function of the gooseneck tube are consistent, and the position of the fan body 22 can be flexibly adjusted so that the position of the cleaning fan 2 can be adaptively adjusted, thus making it suitable for different types of circular knitting machines and improving the practicality of the lint cleaning device. Furthermore, by adjusting the shape of the adjustable bracket 23, the distance and angle between the fan body 22 and multiple yarn feeding components 41 can be adjusted and fixed, so that the fan body 22 is closer to the yarn feeding component 41 and the blowing angle is more accurate, thereby ensuring that the air volume of the fan body 22 is sufficient to blow the lint on the yarn feeding component 41. In addition, the fan body 22 set in this application is a 12V powered fan, which is more energy-saving and has a better energy-saving effect compared with the existing circular knitting machine that uses an air compressor as a cleaning device.

[0022] The power-collecting mechanism 3, mounted on the mounting bracket 1, includes a conductive ring 31 mounted on a fixed ring 11 and connected to an external power source, and a power-collecting carbon brush 32 mounted on a rotating gear ring 12 and electrically connected to multiple cleaning fans 2 via wires. The power-collecting carbon brush 32 is in contact with the conductive ring 31, and the carbon brush 32 remains in contact with the conductive ring 31 throughout the rotation of the rotating gear ring 12. Through the cooperation between the conductive ring 31 and the power-collecting carbon brush 32, the wires of multiple cleaning fans 2 can be connected to the same power-collecting carbon brush 32. During the rotation of the rotating gear ring 12, the power-collecting carbon brush 32 rotates along with the rotating gear ring 12 and the multiple cleaning fans 2, maintaining constant contact with the conductive ring 31. Furthermore, the positions of the wires of the multiple cleaning fans 2 and the power-collecting carbon brush 32 are relatively fixed, preventing entanglement, and the wire layout is reasonable. For ease of subsequent maintenance; specifically, the power-collecting carbon brush 32 includes a base 33 set on the top of the rotating toothed ring 12, a positive carbon brush 34 and a negative carbon brush 35 set on the base 33, and two wire connection ports 36 set on the top of the base 33 corresponding to the positive carbon brush 34 and the negative carbon brush 35 respectively; further, the conductive ring 31 includes a positive conductive ring 37 and a negative conductive ring 38 set at intervals on the top of the fixed ring 11, the positive carbon brush 34 contacts the positive conductive ring 37 and conducts electricity, and the negative carbon brush 35 contacts the negative conductive ring 38 and conducts electricity; further, the drive motor 15 can be connected to an external power supply or electrically connected to the conductive ring 31 through a wire; wherein, the wires of the drive motor 15, the conductive ring 31 and the external power supply are located below the mounting bracket 1, and are set separately from the wires of the cleaning fan 2, so that they do not affect each other.

[0023] In summary, by utilizing the above-mentioned technical solution of this utility model, the lint on multiple yarn feeding components 41 can be cleaned in a timely manner through the cooperation between the mounting bracket 1 on the circular knitting machine 4, the multiple cleaning fans 2 spaced apart on the top of the rotating toothed ring 12, and the power-taking mechanism 3 on the mounting bracket 1. This prevents the lint on the yarn feeding components 41 from accumulating into clumps and falling into the woven fabric roll, thus improving the lint removal effect and improving the quality of the fabric roll. In addition, through the cooperation between the power-taking carbon brush 32 on the top of the rotating toothed ring 12 and the positive conductive ring 37 and negative conductive ring 38 on the fixed ring 11, the wires of multiple cleaning fans 2 can be connected to the same power-taking carbon brush 32. During the rotation of the rotating toothed ring 12, the power-taking carbon brush 32 rotates with the rotating toothed ring 12 and multiple cleaning fans 2 and always maintains contact with the conductive ring 31. Furthermore, the positions of the wires of multiple cleaning fans 2 and the power-taking carbon brush 32 are relatively fixed and will not become tangled. The wire layout is reasonable and facilitates subsequent maintenance.

[0024] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model application and the contents of the specification should still fall within the scope of the present utility model application.
