Description

Technical Field

[0001] This utility model relates to the field of rapier looms, and in particular to a rapier loom weft feeding device with a quick-change jacket. Background Technology

[0002] Rapier looms play a crucial role in the modern textile industry. Their core function lies in efficiently and precisely performing weft feeding to weave fabrics that meet quality requirements. The weft feeding mechanism, as a key component of the rapier loom, directly impacts the loom's production efficiency, product quality, and operational stability.

[0003] A search revealed an existing high-efficiency weft feeding mechanism for a rapier loom, with publication number CN220597750U. This mechanism includes a transmission gear and a rack. The transmission gear is connected to a rotary power mechanism via a transmission shaft. The rack meshes with the transmission gear and has grooves on both sides. It also includes a jacket and a weft feeding guide sleeve. The jacket is fixed to a retaining strip, and multiple guide tracks are provided on its outer sides. A weft feeding rapier head is fixed to the side of the jacket away from the transmission gear. The weft feeding guide sleeve is fixed to the frame of the rapier loom and movably sleeved on the upper outer side of the jacket. Multiple sets of guide wheels that cooperate with the guide tracks are provided on the weft feeding guide sleeve. This utility model provides a rapier loom weft feeding device with a quickly replaceable jacket. The weft feeding rapier head has good linearity, and through the cooperation of the external guide tracks and guide wheels, it adopts an external rolling guidance method. During the movement of the weft feeding rapier head, the weft feeding mechanism generates relatively little heat and can dissipate heat quickly.

[0004] In actual production, the jacket, as a crucial component of the weft feeding mechanism, is prone to wear and damage due to long-term contact and friction with the weft yarn and other parts, requiring periodic replacement. However, the jacket replacement process is cumbersome for weft feeding mechanisms that are directly fixed with bolts. Operators typically need to use tools and go through multiple tedious steps to disassemble and install the jacket. For example, multiple fixing bolts must be removed first, followed by precise alignment and retightening. This not only consumes a significant amount of time and manpower but also increases the workload of the operators. Furthermore, bolts are prone to jamming and rusting after prolonged use, further complicating the unlocking process. Inaccurate alignment during replacement can also lead to an insecure jacket installation, affecting the stability of the jacket during weft feeding, consequently impacting the weft yarn feeding accuracy, and ultimately reducing fabric quality.

[0005] Therefore, it is necessary to provide a new rapier loom weft feeding device with quick-change jacket to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a rapier loom weft feeding device with a quick-change jacket.

[0007] This utility model provides a quick-change sleeve-equipped weft feeding device for a rapier loom, comprising: a fixed base, on which an mounting plate is installed and connected, a weft feeding guide sleeve is fixedly connected to the mounting plate, a sleeve is provided in the weft feeding guide sleeve, a rack is installed and connected in the sleeve, a drive gear is installed and connected to the lower end of the fixed base, the drive gear is located below the rack, and the drive gear meshes with the rack; and a quick-change mechanism, comprising an alignment insert, alignment slots are provided on the inner walls of both ends of the sleeve, two mounting grooves are symmetrically provided on one side wall of the sleeve, an internal tube is fixedly connected to each of the two mounting grooves, a limiting clip is provided at one end of each of the two internal tubes, and a reset component is provided inside each of the two internal tubes.

[0008] Preferably, locking holes are provided on both ends of the alignment insert, and the two limiting clips are respectively aligned with the two locking holes.

[0009] Preferably, the reset assembly includes a stop rod, which is slidably connected to one end wall of the built-in tube, one end of the stop rod is fixedly connected to a limiting clip, and the other end of the stop rod is fixedly connected to a magnetic plate. A spring is sleeved on the stop rod, one end of the spring is connected to the magnetic plate, and the other end of the spring is connected to the inner wall of one end of the built-in tube.

[0010] Preferably, an electromagnet is fixedly connected to the other end of the inner tube, and the electromagnet has opposite magnetic poles to the magnetic plate.

[0011] Preferably, the limiting head is a wedge-shaped block.

[0012] Preferably, multiple limiting strips are provided on both sides of the rack, and multiple limiting grooves are symmetrically provided on both sides of the inner wall of the sleeve, with the multiple limiting strips slidably connected to the multiple limiting grooves respectively.

[0013] Preferably, the weft feeding guide sleeve has multiple wheel grooves on both side walls, and auxiliary rollers are installed and connected inside each of the multiple wheel grooves.

[0014] Compared with related technologies, the rapier loom weft feeding device with quick-change collet provided by this utility model has the following advantages:

[0015] 1. This utility model achieves initial positioning by aligning and sliding the clip with the rack, utilizing the cooperation of the rack's upper limit bar and the limiting groove. Simultaneously, the unique structure of the alignment insert and the limiting clamp head automatically completes the installation and locking of the clip. When the alignment insert approaches the limiting clamp head, the limiting clamp head can accurately engage with the locking port, enabling the clip replacement process to be completed quickly and ensuring the clip's locking status in real time. This facilitates the installation and replacement of the clip, effectively avoiding the problem of unstable weft feeding caused by untimely clip wear and replacement, thereby ensuring the high efficiency and stability of weft feeding on the rapier loom, and improving weaving quality and production efficiency.

[0016] 2. This utility model achieves quick unlocking by using electromagnets to generate magnetism. By controlling the energization of two electromagnets, the magnetic force generated by the electromagnets attracts the magnetic plate to move, thereby driving the stop rod and the limit clamp to leave the locking groove, easily completing the unlocking operation of the sleeve. This unlocking method is simple and convenient, avoiding the cumbersome steps and tools that may exist in traditional unlocking methods, reducing the time and difficulty required to replace the sleeve, and enabling timely replacement of the sleeve to ensure its good condition. This makes the sleeve more accurate in driving the weft feeding process, reducing the deviation of weft yarn introduction, and further improving the quality of weaving and the stability of production.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1 to 3A quick-change weft feeding device for a rapier loom includes: a fixed base 1, an mounting plate 2 mounted on the fixed base 1, a weft feeding guide sleeve 21 fixedly connected to the mounting plate 2, a sleeve 3 provided in the weft feeding guide sleeve 21, a rack 31 mounted in the sleeve 3, a drive gear 32 mounted at the lower end of the fixed base 1, the drive gear 32 being located below the rack 31, and the drive gear 32 meshing with the rack 31; and a quick-change mechanism, including an alignment insert 4, alignment slots provided on the inner walls of both ends of the sleeve 3, two symmetrical mounting grooves 41 provided on one side wall of the sleeve 3, an internal tube 42 fixedly connected to each of the two mounting grooves 41, a limiting clip 43 provided at one end of each of the two internal tubes 42, and a reset component provided inside each of the two internal tubes 42.

[0023] In the specific implementation process, such as Figure 1 and Figure 2 As shown, locking holes are provided on both ends of the side wall of the alignment strip 4, and two limiting heads 43 are respectively aligned with the two locking holes.

[0024] It should be noted that the alignment insert 4 and the alignment slots on the inner walls of both ends of the sleeve 3 cooperate to play a positioning role and ensure the accuracy of the installation position of the sleeve 3.

[0025] The limit clamp 43 is aligned with the locking port so that after the sleeve 3 is installed in place, the limit clamp 43 can smoothly engage with the locking port, achieving a firm connection between the sleeve 3 and the alignment strip 4, thereby ensuring the stability of the entire weft feeding mechanism, enabling the automatic and quick installation and locking of the alignment strip 4 and the sleeve 3, and making the replacement of the sleeve 3 faster and more convenient.

[0026] refer to Figure 2 and Figure 3 As shown, the reset assembly includes a push rod 5, which is slidably connected to one end of the inner tube 42. One end of the push rod 5 is fixedly connected to the limiting head 43, and the other end of the push rod 5 is fixedly connected to a magnetic plate 51. A spring 52 is sleeved on the push rod 5, one end of the spring 52 is connected to the magnetic plate 51, and the other end of the spring 52 is connected to the inner wall of one end of the inner tube 42.

[0027] It should be noted that the function of the reset component is to realize the automatic reset and locking of the limit card head 43. When the alignment insert 4 approaches the limit card head 43, the limit card head 43 is squeezed, which drives the abutment 5 to slide in the inner tube 42. At this time, the magnetic plate 51 moves accordingly and compresses the spring 52, causing the spring 52 to undergo elastic deformation and store energy.

[0028] When the limiting head 43 is aligned with the locking port, the spring 52 releases its elastic potential energy, pushing the magnetic plate 51 and the abutment 5 to move in opposite directions, thereby causing the limiting head 43 to engage with the locking port, completing the installation and locking of the sleeve 3.

[0029] refer to Figure 3 As shown, an electromagnet 53 is fixedly connected to the other end of the inner tube 42. The electromagnet 53 has opposite magnetic poles to the magnetic plate 51.

[0030] It should be noted that: the electromagnet 53 plays an unlocking role when the sleeve 3 needs to be replaced. When the electromagnet 53 is energized, it will generate magnetism. Since the magnetic poles of the electromagnet 53 and the magnetic plate 51 are opposite, an attractive force will be generated, which will attract the magnetic plate 51 to move the push rod 5 towards the electromagnet 53, causing the spring 52 to undergo elastic deformation. The push rod 5 will drive the limit latch 43 to leave the corresponding locking groove, thereby realizing quick unlocking and facilitating the replacement of the sleeve 3. When not energized, the electromagnet 53 does not generate magnetism and will not affect the normal operation of the reset component.

[0031] As shown in the reference figure, the limit stop 43 is a wedge-shaped block.

[0032] It should be noted that the limiting head 43 is designed as a wedge-shaped block. When one end of the alignment strip 4 slides close to the limiting head 43, its inclined side can guide the alignment strip 4 to smoothly squeeze the limiting head 43, so that the limiting head 43 drives the abutment 5 to slide relative to one end of the inner tube 42, which facilitates the installation of the sleeve 3. At the same time, after the wedge-shaped block is inserted into the locking port, it can provide a good locking effect and prevent the sleeve 3 from loosening.

[0033] refer to Figure 1 and Figure 2 As shown, multiple limiting strips 6 are provided on both sides of the rack 31, and multiple limiting grooves are symmetrically provided on both sides of the inner wall of the sleeve 3. The multiple limiting strips 6 are slidably connected to the multiple limiting grooves respectively.

[0034] It should be noted that the cooperation between the limiting strip 6 and the limiting slide groove serves as a guide during the installation of the sleeve 3, ensuring that the sleeve 3 can be accurately aligned with the rack 31 and slide in, thereby improving installation efficiency.

[0035] On the other hand, it can also ensure the relative position between the jacket 3 and the rack 31 is stable, thereby making the weft feeding process more accurate and stable.

[0036] refer to Figure 1 and Figure 2 As shown, multiple wheel grooves are provided on both sides of the weft feeding guide sleeve 21, and auxiliary rollers 7 are installed and connected inside the multiple wheel grooves.

[0037] It should be noted that the auxiliary roller 7 can reduce the friction when the sleeve 3 slides in the weft feeding guide sleeve 21. During the weft feeding process of the sleeve 3, the auxiliary roller 7 contacts and rolls with the sleeve 3, converting sliding friction into rolling friction, making the movement of the sleeve 3 smoother, reducing energy loss, and also reducing the wear of the sleeve 3 and the weft feeding guide sleeve 21, extending the service life of the equipment, and improving the working efficiency and stability of the weft feeding mechanism.

[0038] The working principle of the quick-change weft feeding device for a rapier loom provided by this utility model is as follows: After the replacement weft clip 3 is aligned with the rack 31, it slides in, so that multiple limiting strips 6 on the two side walls of the upper end of the rack 31 are aligned with multiple corresponding limiting grooves and slide in simultaneously. When one end of the alignment insert 4 slides close to the oblique side of the limiting clamp 43, the limiting clamp 43 drives the abutment 5 to slide relative to one end of the inner tube 42. The abutment 5 drives the magnetic plate 51 to move accordingly, causing the spring 52 to undergo elastic deformation. Until the limiting clamp 43 is aligned with the locking port, the spring 52 undergoes elastic deformation, causing the abutment 5 to drive the limiting clamp 43 to move in the opposite direction and lock into the locking port. This realizes the quick installation and locking of the alignment insert 4 and the weft clip 3 automatically, making the replacement of the weft clip 3 faster and more convenient, ensuring real-time and quick locking of the weft clip 3, and ensuring greater stability during the efficient weft feeding process of the weft clip 3.

[0039] When replacement is needed, simply energize the two electromagnets 53 to generate magnetism, attract the magnetic plate 51 and move the stop rod 5 accordingly. The spring 52 undergoes elastic deformation, causing the stop rod 5 to move away from the corresponding locking groove along with the limit clip 43 at one end, thus achieving quick unlocking and facilitating the replacement of the clip 3 on the rack 31, ensuring that the clip 3 drives the weft feeding more accurately.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
