Description

Technical Field

[0001] This utility model relates to shuttleless weaving equipment technology, specifically a shuttleless weaving machine with modular quick-change weft insertion units. Background Technology

[0002] Weaving machines are used to weave various materials. Among them, shuttleless weaving machines are mainly divided into rapier looms, air-jet looms, water-jet looms, rapier looms, and multi-shed looms, covering most of the materials on the market.

[0003] For example, publication number CN115138790B, publication date: 2025-03-25, discloses a wire mesh weaving device with adjustable weft beat-up times, including a frame, a warp feeding mechanism, a warp switching mechanism, a weft insertion mechanism, and a winding mechanism, as well as a weft beat-up mechanism. The weft beat-up mechanism includes a swing arm, a drive structure, an adjusting component connecting the swing arm and the drive structure, a first connecting rod connecting the swing arm, a rotating rod connecting the first connecting rod, a second connecting rod connecting the first connecting rod, and a weft pusher assembly connecting the second connecting rod. When the first and second connecting rods are collinear, the height of the swing arm is a first height. When the maximum swing height of the swing arm is at the first height, the weft pusher assembly performs one weft beat-up within one swing cycle. When the maximum swing height of the swing arm is higher than the first height, the weft pusher assembly performs two weft beat-ups within one swing cycle. The wire mesh weaving device with adjustable weft beat-up times provided by this invention allows for changing the number of weft beat-ups by the weft pusher assembly within one swing cycle, ensuring that the weft yarn is pushed into place and guaranteeing product quality.

[0004] The shortcomings of the existing technology are that the weft insertion unit module of the braiding machine needs to be used on the basis of the warp and weft swing rod. During the operation of the warp and weft swing rod, continuous vibration is generated during the movement. If the vibration frequency is close to the natural frequency of the module component, resonance will occur, which will damage the weft insertion unit module component. Even if resonance does not occur during the vibration, the vibration alone will cause the bolts of the swing rod and its connecting plates and rods to loosen, which will aggravate the deviation of the swing rod position and cause a series of metal fatigue and other problems, affecting the guidance of the yarn by the weft insertion unit module and causing problems such as yarn breakage during braiding. Utility Model Content

[0005] The purpose of this invention is to provide a shuttleless knitting machine with modular quick-change weft insertion units to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A modular quick-change weft insertion unit shuttleless knitting machine includes a weft insertion module and a swing arm with an installation port, wherein symmetrically distributed protrusions are fixedly installed on the installation port.

[0008] It also includes a buffer ring with a connecting pad, the buffer ring fitting into the mounting opening, and the connecting pad abutting between the two protrusions.

[0009] As a further description of the above technical solution: the buffer ring is provided with a circumferentially arranged concave section.

[0010] As a further description of the above technical solution: the outer wall of the buffer ring is provided with equally spaced outer grooves.

[0011] As a further description of the above technical solution: the inner wall of the buffer ring is provided with equidistant inner grooves that are staggered from the outer grooves.

[0012] As a further description of the above technical solution: the concave section is provided with a through hole communicating with the inner groove.

[0013] As a further description of the above technical solution: the connecting pad has equidistant and interconnected perforations.

[0014] As a further description of the above technical solution: any of the perforations and the holes opened on the boss are connected.

[0015] As a further description of the above technical solution: the end of the connecting pad is fixedly installed with symmetrically distributed shoulders that are connected to the buffer ring.

[0016] As a further description of the above technical solution: a notch is provided in the mounting port, and the shoulder is driven to move toward the notch.

[0017] As a further description of the above technical solution: the buffer ring is specifically a rubber ring.

[0018] In the above technical solution, the modular quick-change shuttleless knitting machine of the present invention has the following beneficial effects: by placing the buffer ring in the mounting port, and then fitting the end shaft of the plate or the end shaft of the roller with the inner ring of the buffer ring, the buffer ring plays a buffering and energy-absorbing role, effectively suppressing vibration transmission. The connecting pad is used to transfer the buffering capacity to the boss, which can directly absorb and buffer the vibration force on the bolt, thereby reducing the damage caused by vibration to the swing arm on the weft insertion unit module and protecting the safety of the components.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-5 This utility model provides a technical solution, including the following embodiments:

[0029] Example 1

[0030] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment provides a buffer reinforcement component at the original bolt fixing position, namely a rubber buffer ring 2 integrally formed with a connecting pad 25. By placing the buffer ring 2 in the mounting opening 12, and then fitting the end shaft of the plate or the end shaft of the roller with the inner ring of the buffer ring 2, the buffer ring 2 can play a buffering and energy-absorbing role, effectively suppressing vibration transmission. The connecting pad 25 is used to transfer the buffering capacity to the boss 13, which can directly absorb and buffer the vibration force on the bolt, thereby reducing the damage caused by vibration to the swing arm on the weft insertion unit module and protecting the safety of the components.

[0031] Specifically, the concave section 21 is integrally formed on the buffer ring 2. The concave section 21, which is recessed into the inner diameter of the buffer ring 2, increases the friction between the buffer ring 2 and the mounting port 12 and the shaft, thereby improving the anti-slip effect.

[0032] Furthermore, the weft insertion module 1 is a partial weft insertion unit module of the knitting machine, and there are multiple swing arms 11, which are used on the weft insertion module 1. This is existing technology and will not be described in detail here.

[0033] Example 2

[0034] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment details the excellent anti-slip and heat dissipation effects of the buffer ring 2. Through the multiple inner grooves 23 and outer grooves 22 distributed internally and externally, the friction is maximized and the anti-slip effect is optimal after the inner and outer walls of the buffer ring 2 are installed. Furthermore, the staggered distribution of the inner grooves 23 and outer grooves 22 not only makes reasonable use of the effective width of the buffer ring 2 to ensure the cushioning effect, but also allows the buffer ring 2 to develop the ability to spread and deform axially during long-term use and aging, thereby creating a wrinkled effect in the inner grooves 23 and outer grooves 22, further enhancing the anti-slip capability.

[0035] Secondly, due to the additional bulge of the concave section 21, the process of opening the annular inner groove 23 promotes the formation of the through hole 24, which penetrates the entire buffer ring 2. This allows the through hole 24 to have the function of ventilation inside and outside the buffer ring 2, thereby forming a certain heat dissipation function and reducing the thermal damage to the buffer ring 2 caused by heat.

[0036] Specifically, multiple grooves and holes are opened on the buffer ring 2, which not only improves the performance of the buffer ring 2, but also reduces the cost of materials, resulting in a simpler structure and better performance.

[0037] Example 3

[0038] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this embodiment provides a component that maintains a certain level of good performance even after the buffer ring 2 ages, namely the shoulder 26 that moves with the connecting pad 25. By changing the through hole 27 through which the bolt needs to pass, the connecting pad 25 can be pulled away from the mounting port 12. Then, the bolt is used to maintain the compression of the connecting pad 25. Then, the aged buffer ring 2 is manually pulled. At this time, the extra arc length of the multiple concave sections 21 increases on the buffer ring 2 as it is pulled, causing more rubber to accumulate in the notch 14. This results in more rubber at the shoulder 26, greater resistance, and a tighter fit. This makes the rubber at this position reinforce the vibration damping between the bolt and the mounting port 12, achieving excellent buffering effect even after the buffer ring 2 ages.

[0039] Specifically, as the connecting pad 25 is pulled, the shoulder 26 adds more rubber between the two protrusions 13, which allows more rubber to directly protect the bolt, thereby reducing the bolt damage problem, ensuring the stability between the swing arm 11 and the plate and roller, reducing the interference of the weft insertion unit module on the yarn, and ensuring the efficiency of weaving production.

[0040] Furthermore, the shoulder 26 is integrally formed on the connecting pad 25, which ensures the structural strength of the rubber during use, and can also deform with tension, facilitating buffering and transmission.

[0041] Furthermore, the shoulder 26 is rounded, which makes it easy to enter through the gap between the two protrusions 13 during the pulling process, so that any of the holes 27 on the connecting pad 25 can correspond to the bolt.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
