Description

Technical Field

[0001] This utility model relates to a twisting machine, and more particularly to a twisting machine for chemical fiber filaments with a three-layer twisting unit. Background Technology

[0002] The development of chemical fiber twisting machines in China began in the 1990s and has spanned over two decades. The customer base for twisting machines has shifted from a scattered state (many customers, few machines) to a more concentrated customer base. Due to the high twisting degree required for chemical fiber filament twisting, a large number of machines are needed. Currently, customers have anywhere from several thousand to tens of thousands of machines. This necessitates significant factory space, objectively increasing investment costs. Traditional chemical fiber twisting machines are double-layered devices. For example, a general-purpose twisting machine disclosed in Chinese Patent Publication No. CN2401572Y, published on October 18, 2000, includes a frame and motors and gear transmission devices located at both ends of the frame. The frame is a double-layered frame, with bobbin supports on both sides of the upper end of each layer and spindle components on both sides of the lower end. Each spindle component is in frictional engagement with a belt running through the frame. The two ends of the belt are connected to the motor and the gear transmission device, respectively. The spindle component is characterized by including a yarn can, a tensioner, and a rotor assembly. A stationary disc is fixed to the outer side of the bottom of the yarn can, and an inner magnet is fixed to the inner side of the bottom. The rotor assembly is located at the lower end of the stationary disc, and a tensioner is located at the upper end. The tensioner consists of a tension tube, a spindle blade, and a hollow shaft. The spindle blade is sleeved on the upper end of the hollow shaft, and the tension tube is sleeved on the lower end of the hollow shaft. Alternatively, a doubling twister disclosed in Chinese Patent Publication No. CN210066005U, published on February 14, 2020, includes a frame. The frame is a double-layer frame, which includes a base, an upper twisting unit, and a lower twisting unit. By adding a rotating lifting device, the balance of the twisting unit is maintained, preventing the yarn bobbins of the twisting unit from becoming tangled in stripes. This makes it more convenient and faster for workers to change yarn bobbins, improving the changing speed and greatly increasing production efficiency.

[0003] The spindle, as one of the main components of the spinning machine for twisting and winding, is an assembly with a slender rotating shaft supported at two points. Spindles are found on roving frames, spinning frames, and twisting machines. A roving spindle is a round steel rod with a groove at the top to support and drive the spindle wings to rotate. The lower end, at the spindle tip, has a spindle foot oil cup for support, and the middle section uses a spindle sleeve as the upper bearing. A spinning spindle consists of a spindle rod, spindle disc, support components (commonly known as the spindle core), spindle hook, spindle foot, and brake.

[0004] As can be seen from the aforementioned patents, the structure of traditional doubling twisters consists of two layers of twisting units, such as... Figure 1As shown, the reason for the limitation on the number of layers is that the bottom of the traditional chemical fiber spindle 1a is provided with spindle feet 2a, and the overall height of spindle 1a is caused by the presence of spindle feet 2a. As a result, the height of each twisting unit is relatively high. If three twisting units are stacked, the position of the highest layer will be too high. Not only will the height of the factory building need to be increased, but the staff will also be unable to directly operate the equipment on the highest layer without the help of climbing tools. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a three-layer chemical fiber filament twisting machine that can reduce the height of each twisting unit.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a chemical fiber filament twisting machine with three layers of twisting units, including a twisting unit, which includes an upper twisting unit, a middle twisting unit and a lower twisting unit. Each twisting unit is provided with spindles arranged from left to right. A horizontally set mounting plate is fixed on the twisting unit. The mounting plate has a mounting hole for the bottom of the spindle rod to pass through. The part of the spindle rod that passes through the mounting hole and extends to the lower part of the mounting plate is the driving end. The spindle rod and the mounting hole are rotated together by a bearing. A driving unit for driving the spindle rod to rotate is provided below the mounting plate.

[0007] The beneficial effects of this utility model are as follows: the spindle is mounted on the mounting plate, and the spindle rod on the spindle and the mounting hole are rotated through the bearing. Then, the spindle rod is driven to rotate through the drive unit, thereby realizing the rotation of the spindle. Compared with the traditional spindle, the spindle foot structure is omitted, which can reduce the overall height of the spindle to a certain extent, and thus the height of the twisting unit can also be reduced accordingly. This achieves a three-layer twisting unit structure. At this time, when the staff is standing on the ground, they can also conveniently operate the spindle and other equipment in the upper twisting unit.

[0008] Further configuration: the drive unit is a drive motor, and the output shaft of the drive motor is coaxially fixed with the drive end. The drive motor can be a miniaturized model, which can minimize the height of the spindle, thereby meeting the working requirements of the three-layer twisting unit.

[0009] The drive unit is further configured as follows: it includes a spindle disk fixed to the drive end, a belt for driving the spindle disk to rotate, and a belt motor for driving the belt motor to rotate. The rotation of the spindle disk is achieved through the belt motor, which in turn drives the rotation of the spindle. Since the belt motor drive eliminates the need for spindle feet, it reduces the height of the spindle. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] Example 1: As Figures 1-5 As shown, this embodiment includes twisting units arranged sequentially from top to bottom. Each twisting unit is a top twisting unit a, a middle twisting unit b, and a bottom twisting unit c. Each twisting unit contains several working units arranged sequentially from left to right. Each working unit includes a spindle 2, a gas ring guide 3, an overfeed roller 4, a wire guide 5, a friction wheel 6, and a winding bobbin 7. A horizontally mounted mounting plate 91 is fixed within each twisting unit. The mounting plate 91 has a mounting hole 92 through which the bottom of the spindle rod 21 on the spindle 2 passes. The portion of the spindle rod 21 extending through the mounting hole 92 and below the mounting plate 91 is the drive end 21a. The spindle rod 21 and the mounting hole 92 are rotated together by a bearing 22. A drive unit for driving the spindle rod 21 to rotate is located below the mounting plate 91. In this embodiment, the drive unit is a drive motor 1, and the drive end 21a of each spindle is coaxially fixed to the output shaft of one drive motor 1. The drive motor 1 is fixedly mounted below the mounting plate 91 by screws. The drive motor 1 can be a miniaturized model, which can minimize the height of the spindle and thus meet the working requirements of the three-layer twisting unit.

[0019] In this invention, the spindle 2 is mounted on the mounting plate 91, and the spindle rod 21 on the spindle 2 and the mounting hole 92 are rotated together by the bearing 22. Then, the spindle rod 21 is driven to rotate by the drive motor 1, thereby realizing the rotation of the spindle 2. Compared with the traditional spindle, the spindle foot structure is omitted, which can reduce the overall height of the spindle 2 to a certain extent, and thus the height of the twisting unit can also be reduced accordingly. This achieves a three-layer twisting unit structure, so that when the operator is standing on the ground, he can easily operate the spindle and other equipment in the upper twisting unit.

[0020] Example 2: Figure 6 , 7 As shown, the main difference between this embodiment and Embodiment 1 lies in the driving unit. In this embodiment, the driving unit includes a spindle disk 23 fixed on the driving end 21a, a belt 24 for driving the spindle disk 23 to rotate, and a belt motor (not shown in the figure) for driving the belt 24 to rotate. The rotation of the spindle disk 23 is achieved by the belt 24, which in turn drives the spindle 2 to rotate. The belt 24 driving method does not require spindle feet, thereby reducing the height of the spindle 2.
