Abstract

This utility model discloses a textile machinery heddle weaving device, including a frame, a shock-absorbing mechanism installed at the bottom of the frame, an inverted U-shaped support mounted on the frame, a drive mechanism installed between the inner walls of the U-shaped support, and a heddle frame installed below the drive mechanism. This device, by incorporating a shock-absorbing mechanism with dampers and a first spring installed at the four corners of the frame bottom, and utilizing the cooperation of a connecting rod, sliding ring, connecting piece, and second spring, effectively absorbs and buffers vibrations generated during operation, reducing the impact of vibrations on the device's stability and service life, and lowering maintenance costs. The drive mechanism employs an eccentric component and roller design. A motor drives the eccentric component to rotate, causing the roller to roll within a limiting ring, thereby driving a sliding rod to slide up and down within a sleeve. This, in turn, enables the heddle frame to perform precise and stable up-and-down movement, improving the weaving quality of the textile.

Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and more specifically, to a textile machinery heddle weaving device. Background Technology

[0002] In textile production, heddle weaving is a crucial process, and the performance of the equipment directly affects the quality and production efficiency of textiles. Traditional textile machinery heddle weaving devices suffer from several problems during operation. Firstly, the devices generate significant vibrations during operation. These vibrations not only affect the stability and lifespan of the device but may also lead to accelerated wear of loom components, increasing maintenance costs. Simultaneously, vibrations generate noise, polluting the working environment and harming the health of operators. Secondly, the drive mechanism design of existing heddle weaving devices may be inadequate, resulting in inaccurate and unstable movement of the heddle frame, thus affecting the weaving quality of textiles and causing problems such as uneven fabric texture and increased defects. Therefore, improvements to textile machinery heddle weaving devices are needed to address these issues.

[0003] According to patent publication number CN213013272U, a textile machinery heddle weaving device includes a textile machine body, a motor, a reducer, an eccentric assembly, a push-pull rod, a heddle, a heddle aluminum frame, and an aluminum frame support. The upper ends of the textile machine body are connected to both sides of the aluminum frame support. The heddle aluminum frame is slidably connected to the aluminum frame support. A heddle is connected to the center of the heddle aluminum frame. One end of the push-pull rod is connected to a spherical bearing. One end of the heddle aluminum frame is rotatably connected to the spherical bearing on the push-pull rod via bolts. The other end of the push-pull rod is threaded. The lower end of the support is connected to a motor, and the upper end of the support is connected to a reducer. The output shaft of the motor and the input shaft of the reducer are rotatably connected via a transmission belt. The output shaft of the reducer is connected to one end of a first rotating shaft. Two eccentric assemblies are connected to the first rotating shaft. The other end of the first rotating shaft is rotatably connected to a positioning auxiliary block via a first bearing. The eccentric assembly is threadedly connected to one end of the push-pull rod.

[0004] The shortcomings of the aforementioned device are as follows: Regarding vibration damping, it lacks a dedicated damping mechanism, allowing vibrations to be directly transmitted to the textile machine body. This leads to decreased device stability, loose component connections, increased risk of malfunction, and reduced lifespan. Furthermore, the lack of a multi-dimensional buffer structure makes it difficult to handle vibrations from multiple directions and frequencies. In terms of heald frame movement, the use of an eccentric assembly connected to a push-pull rod via threaded connections to drive the aluminum heald frame is prone to wear and loosening over time, affecting movement accuracy. The push-pull rod connects to the aluminum heald frame via a spherical bearing, resulting in wobbling during movement and poor stability, which is detrimental to improving weaving quality. Utility Model Content

[0005] The purpose of this invention is to provide a textile machinery heddle weaving device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a textile machinery heddle weaving device, comprising a frame, a shock-absorbing mechanism installed at the bottom of the frame, an inverted U-shaped bracket installed on the frame, a driving mechanism installed between the inner walls of the U-shaped bracket, and a heddle frame installed below the driving mechanism.

[0007] As a preferred technical solution of this utility model, the driving mechanism includes a sleeve disposed at the top of the inverted U-shaped bracket, a sliding rod slidably connected inside the sleeve and passing through its bottom, a vertical limiting groove being opened on the side of the sleeve, and a helical frame being fixedly connected to the bottom of the sliding rod.

[0008] As a preferred technical solution of this utility model, the side of the slide rod is fixedly connected to the middle of the side of the limiting ring through the limiting groove via a connecting rod.

[0010] As a preferred embodiment of this utility model, a connecting rod is fixedly installed between the sides of the mounting block, a pair of sliding rings are slidably connected on the connecting rod, a connecting member is installed above the sliding rings via a rotating component, the connecting member is installed above the bottom of the frame via a rotating component, and a second spring is fixedly connected between the sliding rings.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

Detailed Implementation

[0021] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0022] Please see Figure 1-4 According to an embodiment of the present invention, a textile machinery heddle weaving device includes a frame 1, a shock-absorbing mechanism 2 installed at the bottom of the frame 1, an inverted U-shaped bracket 3 installed on the frame 1, a driving mechanism 4 installed between the inner walls of the U-shaped bracket 3, and a heddle frame 5 installed below the driving mechanism 4.

[0023] The frame 1 serves as the supporting foundation for the entire textile machinery heddle weaving device, bearing the weight of other components. The shock absorption mechanism 2 reduces vibrations generated during operation, protecting the device and improving operational stability. The inverted U-shaped bracket 3 provides mounting support for the drive mechanism 4. The drive mechanism 4 drives the heddle frame 5 to move up and down, realizing the heddle weaving function. The heddle frame 5 moves under the drive of the drive mechanism 4, participating in the heddle weaving operation of the textile.

[0024] In this embodiment, the drive mechanism 4 includes a sleeve 6 disposed at the top of the inverted U-shaped bracket 3, a sliding rod 7 slidably connected inside the sleeve 6 and passing through its bottom, a vertical limiting groove 8 being opened on the side of the sleeve 6, and a heddle frame 5 being fixedly connected to the bottom of the sliding rod 7.

[0025] The sleeve 6 is located at the top of the inverted U-shaped bracket 3, providing a sliding track and support for the slide rod 7. The slide rod 7 slides within the sleeve 6, driving the heave frame 5 to move up and down. The limiting groove 8 limits the movement of the slide rod 7, ensuring its linear motion.

[0026] In this embodiment, the side of the slide rod 7 is fixedly connected to the middle of the side of the limiting ring 9 through the limiting groove 8 via a connecting rod. The inner wall of the limiting ring 9 is connected to the roller 10. The roller 10 is mounted on one end of the eccentric member 11 via a rotating component. The other end of the eccentric member 11 is mounted on the output end of the motor 12 via a rotating shaft. The motor 12 is fixedly connected to the side wall of the U-shaped bracket 3 via a connecting component.

[0027] The limiting ring 9 is connected to the slide rod 7 via a connecting rod, and works with the roller 10 to realize the up-and-down movement of the slide rod 7. The roller 10 rolls on the inner wall of the limiting ring 9, converting the rotation of the eccentric member 11 into the up-and-down sliding of the slide rod 7.

[0028] In this embodiment, the shock absorption mechanism 2 includes dampers 13 fixed at the four corners of the bottom of the frame 1. A mounting block 14 is installed at the bottom of the damper 13, and a support leg 15 is installed at the bottom of the mounting block 14. A first spring 16 is installed between the mounting block 14 and the frame 1 and wraps around the damper 13.

[0029] The damper 13 initially buffers and absorbs vibrations. The first spring 16 wraps around the damper 13 to further reduce the transmission of vibrations.

[0030] In this embodiment, a connecting rod 17 is fixedly installed between the sides of the mounting block 14. A pair of sliding rings 18 are slidably connected to the connecting rod 17. A connecting member 19 is installed above the sliding rings 18 via a rotating component. The connecting member 19 is installed above the bottom of the frame 1 via a rotating component. A second spring 20 is fixedly connected between the sliding rings 18.

[0031] The sliding ring 18 slides on the connecting rod 17 and is connected to the frame 1 via the connector 19, working in conjunction with the second spring 20 to absorb vibrations. The connector 19 connects the sliding ring 18 and the frame 1, transmitting motion and force.

[0032] The second spring 20 absorbs and disperses vibration energy through elastic deformation.

[0033] In practical applications, the starter motor 12 drives the eccentric component 11 to rotate. Due to the eccentric design of the eccentric component 11, the roller 10 installed at one end of the eccentric component 11 will perform circular motion as the eccentric component 11 rotates. The roller 10 rolls on the inner wall of the limiting ring 9. Since the limiting ring 9 is connected to the sliding rod 7 through a connecting rod, and the sliding rod 7 is restricted to linear motion within the limiting groove 8 in the sleeve 6, the circular motion of the roller 10 is converted into the up-and-down sliding of the sliding rod 7 within the sleeve 6 through the limiting ring 9. The up-and-down sliding of the sliding rod 7 drives the heddle frame 5 to move up and down. The up-and-down movement of the heddle frame 5 realizes the heddle twisting function in the textile process, allowing the warp yarns to interweave according to a predetermined pattern, creating conditions for the introduction of the weft yarn. Vibration will occur during the operation of the device. The dampers 13 installed at the four corners of the bottom of the frame 1 first buffer and absorb the vibration, reducing the transmission of vibration. The first spring 16 will extend and retract according to the amplitude of the vibration, further slowing down the transmission of vibration and protecting other parts of the device. At the same time, the up and down sway of the frame 1 will drive the sliding ring 18 to slide on the connecting rod 17 through the connector 19. The second spring 20 is fixedly connected between the sliding rings 18. When the sliding ring 18 slides, the second spring 20 will undergo elastic deformation, absorbing and dispersing the vibration energy through elastic deformation, thereby further improving the shock absorption effect and ensuring the stability of the device.
