Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and in particular to an automatic textile bobbin changing device. Background Technology

[0002] The original meaning of textiles comes from the general term for spinning and weaving. However, with the continuous development and improvement of the knowledge system and discipline of textiles, especially after the emergence of technologies such as nonwoven textile materials and three-dimensional composite weaving, it is no longer just about traditional hand spinning and weaving. It also includes nonwoven technology, modern three-dimensional weaving technology, modern electrostatic nano-web forming technology, etc., to produce clothing, industrial and decorative textiles. Therefore, modern textiles refer to a multi-scale structural processing technology of fibers or fiber assemblies. Clothing, airbags, curtains and carpets in daily life are all products of textile and dyeing technology.

[0003] In textile processing, yarn is usually wound up using bobbins. To facilitate yarn unwinding, the common practice is to thread the bobbins onto a machine equipped with a fixed rotating shaft and then pull the yarn. After the yarn on the bobbin is used up, it needs to be removed from the fixed rotating shaft and a new bobbin needs to be installed for unwinding. This means that the machine must be stopped and the bobbin replaced before yarn unwinding can continue. The bobbin installation speed is slow, and the surface of the bobbin cannot be pressed during the unwinding process, making the yarn on the bobbin prone to loosening. Utility Model Content

[0004] To address the aforementioned shortcomings in the existing technology, this utility model provides an automatic yarn bobbin replacement device for textiles. The purpose of this device is to solve the problems that require the machine to be stopped and the bobbin replaced before yarn can be continued during yarn feeding, the slow bobbin installation speed, and the inability to press the surface of the bobbin during the feeding process, which can easily cause the yarn on the bobbin to become loose.

[0007] Furthermore, the bobbin fixing mechanism includes a second turntable rotatably connected to the first turntable. The second turntable has four strip-shaped grooves arranged in a circumferential array. A support plate is slidably connected in the strip-shaped grooves. A second connecting shaft is slidably connected to the second turntable. Several evenly distributed connecting rods are arranged between the second connecting shaft and the support plate. A second bracket is fixedly welded to the first turntable. A second motor is installed on the second bracket. A drive assembly is arranged between the output shaft of the second motor and the second connecting shaft.

[0008] Furthermore, the two ends of the connecting rod are respectively hinged to the second connecting shaft and the support plate.

[0009] Furthermore, the drive assembly includes a mounting groove formed on the second connecting shaft, an electric actuator is installed in the mounting groove, a sliding groove is formed in the mounting groove, a slider is fixedly connected to the output shaft of the second motor, and the sliding groove is slidably connected to the slider.

[0010] Furthermore, both ends of the electric actuator are fixedly connected to the output shaft of the second motor and the second connecting shaft, respectively.

[0011] Furthermore, the clamping mechanism includes a fixed plate fixedly connected to the mounting frame, a plurality of evenly distributed telescopic rods are fixedly installed at the bottom of the fixed plate, springs are sleeved on the outer side of the telescopic rods, and a U-shaped frame is fixedly connected to the side of the telescopic rod away from the fixed plate, and a pressure roller is rotatably connected to the U-shaped frame.

[0021] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0022] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] like Figures 1 to 4 As shown, an automatic textile spool changing device includes a mounting frame 1, a first turntable 2 rotatably connected to the mounting frame 1, a first bracket 3 fixedly mounted on the mounting frame 1, a first motor 4 mounted on the first bracket 3, a first connecting shaft 5 fixedly connected to the output shaft of the first motor 4, the first connecting shaft 5 being fixedly connected to the first turntable 2, and the first motor 4 driving the first turntable 2 to rotate via the first connecting shaft 5.

[0024] The first turntable 2 is provided with two symmetrically arranged spool fixing mechanisms 6. The spool fixing mechanism 6 includes a second turntable 601 rotatably connected to the first turntable 2. The second turntable 601 has four strip-shaped grooves 602 arranged in a circular array. A support plate 603 is slidably connected in the strip-shaped grooves 602. A second connecting shaft 604 is slidably connected to the second turntable 601. A number of evenly distributed connecting rods 605 are arranged between the second connecting shaft 604 and the support plate 603. The two ends of the connecting rods 605 are respectively hinged to the second connecting shaft 604 and the support plate 603. A second bracket 606 is fixedly welded to the first turntable 2. A second motor 607 is installed on the second bracket 606.

[0025] A drive assembly 608 is provided between the output shaft of the second motor 607 and the second connecting shaft 604. The drive assembly 608 includes a mounting groove 618 formed on the second connecting shaft 604. An electric push rod 628 is installed in the mounting groove 618. The two ends of the electric push rod 628 are fixedly connected to the output shaft of the second motor 607 and the second connecting shaft 604, respectively. A sliding groove 638 is formed in the mounting groove 618. A slider 648 is fixedly connected to the output shaft of the second motor 607. The sliding groove 638 is slidably connected to the slider 648.

[0026] When installing the spool, the electric push rod 628 drives the second connecting shaft 604 to move closer to the second motor 607. The second connecting shaft 604 drives the support plates 603 to move closer to each other through the connecting rod 605, so that the spool is sleeved on the outer side of the support plate 603. The electric push rod 628 drives the second connecting shaft 604 to move away from the second motor 607, so that the support plates 603 move away from each other, thus fixing the spool.

[0027] The second motor 607 drives the second connecting shaft 604 to rotate, the second connecting shaft 604 drives the connecting rod 605 and the support plate 603 to rotate, and the support plate 603 drives the spool to rotate, thus feeding the thread on the spool. After the thread on the spool of one spool fixing mechanism 6 is fed out, the first motor 4 drives the first turntable 2 to rotate, automatically changing one spool fixing mechanism 6 and automatically changing the spool without stopping the machine.

[0028] The mounting frame 1 is provided with a pressing mechanism 7, which includes a fixed plate 701 fixedly connected to the mounting frame 1. Several evenly distributed telescopic rods 702 are fixedly provided at the bottom of the fixed plate 701. Springs 703 are sleeved on the outside of the telescopic rods 702. A U-shaped frame 704 is fixedly connected to the side of the telescopic rods 702 away from the fixed plate 701. A pressure roller 705 is rotatably connected to the U-shaped frame 704.

[0029] During the unwinding process, the pressure roller 705 presses the wire on the bobbin under the action of the spring 703, thanks to the pressure mechanism 7. This prevents the wire on the bobbin from loosening during the unwinding process.

[0030] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
