DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Reference Figure 1-5 , please refer to Figure 1-Figure 5 ,in, Figure 1 A schematic diagram of the three-dimensional structure of a fast yarn feeding device of a harness drawing machine proposed by the utility model Figure 1 ; Figure 2 A schematic diagram of the three-dimensional structure of a fast yarn feeding device of a harness drawing machine proposed by the utility model Figure 2 ; Figure 3 It is a partial three-dimensional disassembled structural schematic diagram of a fast yarn feeding device of a harness drawing machine proposed by the utility model; Figure 4 A schematic diagram of the three-dimensional structure disassembly of the installation assembly of a fast yarn feeding device of a drawing-in machine proposed by the utility model Figure 1 ; Figure 5 A schematic diagram of the three-dimensional structure disassembly of the installation assembly of a fast yarn feeding device of a drawing-in machine proposed by the utility model Figure 2 A fast yarn feeding device of a heddle drawing machine comprises: a support base 1, a first support 2 is fixedly mounted on the support base 1, a yarn feeding roller 4 is arranged inside the first support 2, and a mounting assembly 5 is mounted outside the first support 2.

[0025] In the present embodiment, the mounting assembly 5 includes a base cylinder seat 51, a flange 52 is fixedly connected to the outer side of the base cylinder seat 51, a mounting hole 21 is opened on the first support 2, the base cylinder seat 51 is inserted into the inner side of the mounting hole 21, an outer cylinder seat 53 is arranged on the outer side of the flange 52, a cover 54 is arranged on the outer end of the outer cylinder seat 53, a motor 55 is fixedly installed on the side of the cover 54, the output end of the motor 55 rotates through the inner side of the cover 54 and is fixedly installed with a threaded rod 57, a threaded inner cylinder 58 is screwed on the outer side of the threaded rod 57, a plug-in rod 59 is rotatably sleeved on the outer side of the threaded inner cylinder 58, and plug-in holes 41 are arranged at both ends of the yarn feeding roller 4.

[0026] Through the arrangement in the above manner, when the motor 55 rotates, it can drive the threaded rod 57 on the inner side of the cover 54 to rotate. Then, the threaded rod 57 drives the threaded inner cylinder 58 screwed thereto to slide on the inner side of the outer cylinder seat 53 in the rotating state. The threaded inner cylinder 58 further drives the plug-in rod 59 rotatably sleeved on its outer side to slide in the base cylinder seat 51. When the plug-in rod 59 is pushed inward to be plugged into the plug-in hole 41 at the end of the yarn feed roller 4, the yarn feed roller 4 is fixed and limited. The yarn feed roller 4 also has rotational freedom and automatically rotates to discharge material under the traction action during yarn feeding. When the plug-in rod 59 is driven to retract to the inner side of the base cylinder seat 51, the plug-in rod 59 withdraws from the plug-in hole 41. At this time, the fixed limiting effect on the yarn feed roller 4 is cancelled.

[0027] In this embodiment, a second support 3 is disposed on the side of the first support 2 , and a guide roller 6 is rotatably mounted inside the second support 3 .

[0028] Through the above arrangement, the guide roller 6 provides a guiding function for the yarn feeding roller 4 when feeding the yarn.

[0029] In this embodiment, a switch 7 is installed on the side of the first support 2 , and the switch 7 is electrically connected to the motor 55 .

[0030] Through the above-mentioned configuration, the working state of the motor 55 can be controlled by the switch 7 .

[0031] In this embodiment, the flange 52 is screwed to the side of the first support 2, the outer tube seat 53 is screwed to the flange 52, the cover 54 is sleeved on the end of the outer tube seat 53, and the outer side of the cover 54 is provided with a mounting stud 56, and the inner end of the mounting stud 56 is abutted against the outer wall of the outer tube seat 53.

[0032] Through the above-mentioned arrangement, each part of the entire installation assembly 5 is connected by screw connection, which makes the disassembly of the entire installation assembly 5 more convenient and makes the subsequent maintenance or replacement more convenient.

[0033] In this embodiment, the inner diameters of the base cylinder seat 51 and the outer cylinder seat 53 are equal and match the inner diameters of the plug-in rod 59 , and the outer diameter of the plug-in rod 59 is slightly smaller than the inner diameter of the plug-in hole 41 .

[0034] By means of the above arrangement, the outer diameter of the plug-in rod 59 is slightly smaller than the inner diameter of the plug-in hole 41 , so that the plug-in rod 59 can be plugged into the plug-in hole 41 when the yarn feeding roller 4 is fixed and limited.

[0035] In this embodiment, the outer side of the threaded inner cylinder 58 is fixedly connected to a limiting block 510 , and the inner wall of the outer cylinder seat 53 is provided with a limiting groove 511 , and the limiting block 510 is slidably connected to the limiting groove 511 .

[0036] By the above-mentioned arrangement, the sliding connection between the limit block 510 and the limit groove 511 limits the rotational freedom of the threaded inner cylinder 58, thereby preventing the threaded inner cylinder 58 from self-rotating when driven by the threaded rod 57, thereby affecting the transmission efficiency.

[0037] The working principle of a fast yarn feeding device of a harness drawing machine provided by the utility model is as follows:

[0038] When in use, when the gauze on the yarn feeding roller 4 is used up, the switch 7 is used to start the motor 55 to drive the threaded rod 57 to drive the threaded inner cylinder 58 and the plug-in rod 59 that is rotatably sleeved on the outer side of the threaded inner cylinder 58 to retract, so that the inner end of the plug-in rod 59 retracts into the inner side of the base cylinder seat 51, and the limit on the end of the yarn feeding roller 4 is cancelled. The yarn feeding roller 4 is removed from the inner side of the first support 2, and then the new yarn feeding roller 4 filled with sand is placed on the inner side of the first support 2, and the plug-in hole 41 at the end of the yarn feeding roller 4 is aligned with the plug-in rod 59. Subsequently, the motor 55 is started to drive the plug-in rod 59 to be plugged into the plug-in hole 41, and the end of the yarn feeding roller 4 is limited, and then the yarn feeding roller 4 is fixedly installed on the first support 2, and the yarn feeding roller 4 can continue the yarn feeding process.

[0039] Compared with the related art, the fast yarn feeding device of the harness drawing machine provided by the utility model has the following beneficial effects:

[0040] The utility model provides a fast yarn feeding device for a harness drawing machine. The utility model arranges an installation component 5, and utilizes a motor 55 to drive a plug-in rod 59 to slide inward and outward, so that the disassembly and assembly process of a yarn feeding roller 4 is very convenient and quick, and the yarn feeding roller 4 can be replaced relatively quickly, which helps to improve production efficiency and further enhances practicality.
