Description

Technical Field

[0001] This invention relates to the field of textile machinery technology, and in particular to a loom and a fixing device for the loom shedding mechanism. Background Technology

[0002] As an important type of modern high-speed shuttleless loom, the air-jet loom has the advantages of fast weaving speed, high production efficiency and wide adaptability, and is widely used in the textile industry.

[0003] With the continuous development of air-jet loom technology and the increasing market demands for production efficiency, loom operating speeds are constantly rising. Currently, some air-jet looms operate at speeds exceeding 900 rpm, and under high-speed operating conditions, the problem of machine vibration is becoming increasingly prominent.

[0004] Excessive vibration can not only lead to a decline in the surface quality of fabrics, but also cause problems such as accelerated wear of mechanical parts, increased energy consumption, increased noise, and malfunctions of automated control systems, thereby affecting the service life of equipment and production stability.

[0005] Vibration in air-jet looms mainly originates from the following aspects: periodic impacts generated by the reciprocating motion of the beat-up mechanism; centrifugal vibrations caused by the unbalanced rotation of the transmission mechanism; vibrations and impacts generated by the reciprocating motion of the shedding mechanism; and external factors such as the quality of foundation installation, loose anchor bolts, and insufficient ground rigidity.

[0006] Among them, the vibration generated during the operation of the shedding mechanism accounts for an important part of the overall machine vibration. When the shedding mechanism reciprocates at high speed, the periodic inertial load it generates will continuously act on the loom frame, thereby causing the entire machine to vibrate.

[0007] In existing technologies, cam-driven shedding mechanisms or multi-arm shedding mechanisms are typically mounted directly on the loom wall panel, and shedding tie rods are usually mounted on the front and rear lower supports via brackets. The vibration loads generated by the shedding machine and tie rod assembly are mainly transmitted through the loom frame structure, such as the wall panel and lower supports, causing the loom frame to withstand periodic impact loads over a long period.

[0008] Therefore, the existing technology has the following problems: the sheathing machine is rigidly connected to the loom frame device, and the vibration is directly applied to the wall panel; the tie rod assembly is rigidly connected to the front and rear lower supports, and the vibration is directly applied to the loom frame device; the vibration load is mainly concentrated inside the loom frame device structure and is difficult to release effectively; the vibration of the whole machine increases significantly when running at high speed.

[0009] In summary, how to reduce the vibration impact of the shedding mechanism on the loom frame and improve the stability of the loom during high-speed operation is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

Detailed Implementation

[0050] The core of this invention is to provide a loom and a fixing device for the loom shedding mechanism, which enables the vibration load generated during the operation of the shedding mechanism to be diverted and transmitted, thereby reducing the degree of vibration concentration on the loom frame and improving the overall stability of the machine.

[0051] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Example 1:

[0053] like Figures 1-4 As shown, this embodiment provides a fixing device for a shedding mechanism of a loom, applicable to weaving equipment such as air-jet looms and rapier looms that use a shedding mechanism to control the movement of warp yarns. The shedding mechanism includes a shedding machine 5 and a pull rod assembly 6, wherein the shedding machine 5 is used to drive the shedding mechanism to complete the warp yarn shedding movement, and the pull rod assembly 6 is used to transmit the motion output by the shedding machine 5, thereby realizing the shedding movement of the shedding mechanism.

[0054] In existing technologies, the shedding machine is typically mounted directly on the loom wall panel, while the tie rod assembly is usually mounted on the front and rear lower supports. When the loom is running at high speed, the inertial loads and periodic impact loads generated by the shedding machine and tie rod assembly are mainly transmitted through the loom frame devices such as the wall panels and supports, which leads to increased vibration of the loom frame devices. Long-term operation may also cause problems such as loosening of connectors, structural fatigue, and fluctuations in fabric quality.

[0055] To address the aforementioned issues, the fixing device provided in this embodiment includes a shedding machine fixing assembly and a tie rod fixing support assembly. The shedding machine fixing assembly connects the shedding machine 5 to both the loom frame and the ground; the tie rod fixing support assembly supports and fixes the tie rod assembly 6 to the ground. This structure allows the vibration load generated during the operation of the shedding machine 5 to be transmitted to both the loom frame and the ground, while the vibration load generated by the tie rod assembly 6 can be directly transmitted to the ground, thus forming a multi-path vibration load transmission system.

[0056] Specifically, the shedding machine fixing assembly includes a loom frame device connection unit and a ground connection unit. The frame connection unit is connected to the shedding machine 5 and the loom frame device, thereby forming a first load transfer path between the shedding machine 5 and the loom frame device; the ground connection unit is connected to the shedding machine 5 and the ground, thereby forming a second load transfer path between the shedding machine 5 and the ground. The tie rod fixing support assembly is connected to and fixed to the ground by the tie rod assembly 6, thereby forming a third load transfer path between the tie rod assembly 6 and the ground.

[0057] Therefore, in this embodiment, the first load transfer path, the second load transfer path, and the third load transfer path together constitute the diversion and transfer structure of the vibration load of the shearing mechanism. Compared with the single-path transfer method in the prior art, this embodiment can divert and transfer the vibration load to the loom frame device and the ground respectively, so that part of the vibration load is directly transferred to the ground and absorbed by the foundation, thereby reducing the degree of concentrated transmission of vibration energy in the loom frame device, effectively reducing the overall vibration level of the loom, and improving the operational stability of the equipment.

[0058] The loom frame assembly in this embodiment includes a first wall plate 1, a second wall plate 2, a front lower support 3, and a rear lower support 4. The first wall plate 1 and the second wall plate 2 are respectively disposed on both sides of the loom, forming the main load-bearing structure of the loom; the front lower support 3 and the rear lower support 4 are connected between the first wall plate 1 and the second wall plate 2, improving the overall rigidity and stability of the loom frame assembly. The shearing machine 5 is installed in the rear area of ​​the loom, and the tie rod assembly 6 is located in the lower area of ​​the loom.

[0059] The frame connection unit in the opening machine fixing assembly includes a first connecting seat 7, a second connecting seat 8, a first damping element 19, and a second damping element 20. The first connecting seat 7 is fixed to the front side of the opening machine 5, and the second connecting seat 8 is fixed to the rear side of the opening machine 5. The first damping element 19 is disposed between the first connecting seat 7 and the first wall plate 1, and the second damping element 20 is disposed between the second connecting seat 8 and the first wall plate 1.

[0060] The first connecting seat 7 and the second connecting seat 8 are preferably made of welded steel plates, which not only ensures the structural strength and connection rigidity during the installation of the shedding machine 5, but also forms a stable and reliable load transfer channel. In this embodiment, the first connecting seat 7 and the second connecting seat 8 can be made of Q235 steel plate, Q345 steel plate, or other metal materials with sufficient strength and rigidity, and their specific dimensions can be adjusted according to the loom specifications and shedding machine model.

[0061] The first damping element 19 and the second damping element 20 are preferably rubber damping plates. Rubber damping plates have good elastic deformation capacity and energy dissipation capacity, and can absorb some vibration energy during vibration transmission, thereby reducing the transmission of vibration to the loom frame structure. In practical applications, other vibration damping structures such as metal-rubber vibration dampers, composite damping layers, or spring vibration dampers can also be selected according to different loom operating conditions.

[0062] When the shedding machine 5 is running, the vibration it generates is first transmitted to the first connecting seat 7 and the second connecting seat 8, and then transmitted to the loom frame assembly through the first damping element 19 and the second damping element 20. Because the damping elements can generate internal friction and energy loss during vibration, they can effectively reduce the vibration peak value and amplitude, thereby reducing the vibration level of the loom frame assembly. At the same time, due to the flexibility of the damping elements, they can also reduce the rigid impact between the shedding machine 5 and the loom frame assembly, improving the reliability and service life of the connection structure.

[0063] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the first connecting seat 7 and the second connecting seat 8 are fixed to the front and rear sides of the opening machine 5, respectively. The first connecting seat 7 is located on the side of the opening machine 5 near the front lower support 3, and the second connecting seat 8 is located on the side of the opening machine 5 near the rear lower support 4. By setting connecting seats on both the front and rear sides of the opening machine 5, the opening machine 5 can obtain more balanced installation support in the front-rear direction, avoiding the occurrence of eccentric load or local vibration concentration caused by the opening machine 5 being connected only on one side.

[0064] In this embodiment, both the first connecting seat 7 and the second connecting seat 8 can be fixed to the opening machine 5 by bolt connection, welding connection, or a combination of bolt and locating pin connection. Preferably, the first connecting seat 7 and the second connecting seat 8 are connected to the opening machine 5 by bolt connection to facilitate subsequent installation, disassembly, and maintenance. The first connecting seat 7 and the second connecting seat 8 cooperate with the first damping member 19 and the second damping member 20 respectively, so that both the front and rear sides of the opening machine 5 can be connected to the loom frame device through the damping structure, thereby improving connection stability and reducing vibration transmission.

[0065] To further reduce the transmission of vibration to the loom frame, the shedding machine fixing assembly in this embodiment also includes a ground connection unit. The ground connection unit establishes a second load transmission path between the shedding machine 5 and the ground, allowing some of the vibration load generated by the shedding machine 5 to be directly transmitted to the ground without passing through the loom frame, thereby achieving vibration load diversion. When the ground is a concrete foundation, since the mass of the foundation is much greater than the mass of the loom frame, it can effectively absorb vibration energy, further reducing the overall machine vibration level.

[0066] With the fixing device of this embodiment, the vibration load generated by the sheathing machine 5 is no longer entirely applied to the loom frame device, but is instead transmitted to the loom frame device and the ground respectively through the first load transmission path and the second load transmission path; simultaneously, the vibration load generated by the tie rod assembly 6 is transmitted directly to the ground through the third load transmission path. The resulting vibration load diversion and transmission structure can significantly reduce the vibration of the loom frame device, improve the stability of the loom during high-speed operation, reduce mechanical wear and noise levels, and is beneficial to improving fabric quality and equipment service life.

[0067] Example 2:

[0068] Based on Example 1, this example further describes the specific structure of the ground connection unit.

[0069] like Figure 1 , Figure 2 and Figure 4 As shown, the ground connection unit includes a first vibration guide support 21 and a second vibration guide support 22. One end of the first vibration guide support 21 is connected to the first connecting seat 7, and the other end is fixed to the ground; one end of the second vibration guide support 22 is connected to the second connecting seat 8, and the other end is fixed to the ground.

[0070] In this embodiment, both the first vibration guiding support 21 and the second vibration guiding support 22 can adopt a triangular support frame structure. The triangular support frame includes a vertical support rod, an oblique reinforcing rod, and a bottom mounting plate. The upper end of the vertical support rod is connected to the corresponding connecting seat, and the lower end is connected to the bottom mounting plate; one end of the oblique reinforcing rod is connected to the vertical support rod, and the other end is connected to the bottom mounting plate, thereby forming a stable triangular force-bearing structure.

[0071] Due to the high geometric stability of the triangular structure, it is not prone to deformation when subjected to cyclic alternating loads, ensuring that vibration loads are stably transmitted to the ground. Compared with ordinary column-type support structures, triangular support frames can simultaneously withstand vertical loads, lateral loads, and overturning moments, thereby improving the overall rigidity of the opening machine's fixed structure.

[0072] In this embodiment, the first vibration guide support 21 and the second vibration guide support 22 are preferably formed by welding rectangular steel pipes, and the material can be Q235 steel, Q345 steel, or other structural steel materials. The bottom mounting plate is fixedly connected to the ground by anchor bolts. When the ground is a concrete foundation, the anchor bolts can be expansion bolts or pre-embedded bolts.

[0073] The vibrations generated during the operation of the sheathing machine 5 are first transmitted to the first connecting seat 7 and the second connecting seat 8, and then directly transmitted to the ground through the first vibration guide support 21 and the second vibration guide support 22. Since the ground has a much larger mass and stiffness than the loom frame device, it can effectively absorb and dissipate vibration energy, thereby reducing the degree of concentrated transmission of vibration to the loom frame device.

[0074] It should be noted that the present invention is not limited to the triangular support frame structure. In other embodiments, the first vibration guiding support 21 and the second vibration guiding support 22 may also adopt a truss structure, frame structure, plate support structure, box structure, steel composite structure, or other structural forms that can form a load transfer channel between the opening machine and the ground. All the above-mentioned variations are within the protection scope of the present invention.

[0075] By setting the first vibration guide support 21 and the second vibration guide support 22, a stable and reliable second load transmission path is formed between the opening machine 5 and the ground, thereby realizing the active diversion of the vibration load of the opening machine to the ground and improving the vibration reduction effect of the whole machine.

[0076] Example 3:

[0077] Based on Examples 1 and 2, this example further describes the tie rod fixing support assembly.

[0078] like Figures 1 to 3 As shown, the tie rod fixing support assembly includes a first ground support unit and a second ground support unit.

[0079] The first ground support unit is connected to the end support shaft of the tie rod assembly 6, and the second ground support unit is connected to the middle support shaft of the tie rod assembly 6.

[0080] In this embodiment, the first landing support unit includes a first front support 10, a first rear support 11, a first front landing seat 9, and a first rear landing seat 13.

[0081] The upper ends of the first front support member 10 and the first rear support member 11 are respectively connected to the front and rear ends of the end support shaft of the tie rod assembly 6, and the lower ends are respectively connected to the first front landing seat 9 and the first rear landing seat 13.

[0082] The second landing support unit includes a second front support 16, a second rear support 17, a second front landing seat 15, and a second rear landing seat 18.

[0083] The upper ends of the second front support member 16 and the second rear support member 17 are respectively connected to the front and rear ends of the middle support shaft of the tie rod assembly 6, and the lower ends are respectively connected to the second front landing seat 15 and the second rear landing seat 18.

[0084] The first front landing seat 9, the first rear landing seat 13, the second front landing seat 15, and the second rear landing seat 18 are all fixed to the ground.

[0085] In this embodiment, the first front landing seat 9, the first rear landing seat 13, the second front landing seat 15, and the second rear landing seat 18 are all fixed to the ground with anchor bolts. Preferably, each landing seat is provided with mounting holes and is connected to the concrete foundation by expansion bolts or pre-embedded bolts. To improve installation accuracy and support stability, leveling shims or vibration damping shims can also be provided between the landing seat and the ground to compensate for ground flatness errors and improve stress uniformity.

[0086] Through the above structure, the tie rod assembly 6 forms a ground support system independent of the loom frame device.

[0087] In existing technologies, tie rod assemblies are typically installed on the front and rear lower supports, so the vibrations generated during the operation of the tie rod assembly directly affect the loom frame structure. However, in this embodiment, the main supporting force of the tie rod assembly 6 is borne by the ground, and the vibration load is directly transmitted to the ground through the support and the floor seat, thereby preventing the vibration from being transmitted through the loom frame structure.

[0088] In this embodiment, two sets of ground support units are used to support the end and middle positions of the tie rod assembly 6 respectively, thereby improving support stability, reducing bending deformation of the support shaft, and reducing the swaying phenomenon generated during high-speed operation.

[0089] The first front support 10, the first rear support 11, the second front support 16, and the second rear support 17 are preferably formed by steel profiles or welded steel plates. Their cross-sectional shapes can be rectangular tubes, square tubes, channel steel, or I-beams, depending on actual needs.

[0090] The first front landing seat 9, the first rear landing seat 13, the second front landing seat 15, and the second rear landing seat 18 preferably adopt a steel base structure and are fixedly connected to the ground by anchor bolts.

[0091] With the above structure, the vibration generated by the tie rod assembly 6 can be directly transmitted to the ground through the third load transmission path, thereby further improving the vibration load diversion effect.

[0092] Example 4:

[0093] Based on Example 3, in order to further improve the overall rigidity of the support structure, a connecting frame is provided in this example.

[0094] Specifically, a connecting frame is provided between the first front support member 10 and the first rear support member 11.

[0095] A connecting bracket 12 is also connected between the second front support member 16 and the second rear support member 17.

[0096] The connecting frame is not only used to connect the front and rear support members, but also to improve the overall structural rigidity of the support unit. When the tie rod assembly 6 generates periodic alternating loads during operation, the connecting frame can limit the relative displacement between the front and rear support members, reduce local structural deformation, and distribute the load among multiple support members, thereby reducing stress concentration and improving the fatigue resistance and long-term operational reliability of the support structure.

[0097] The connecting frame can connect the front and rear support components in the same support unit into a whole structure, thereby improving the overall stability of the support system.

[0098] When the tie rod assembly 6 generates lateral vibration or torsional load during operation, the connecting frame can effectively limit the relative displacement between the front and rear supports, reduce structural deformation, and improve support accuracy.

[0099] In this embodiment, the connecting frame preferably adopts the connecting angle iron 12 structure.

[0100] The two ends of the connecting angle iron 12 are welded to the corresponding support components respectively.

[0101] In other embodiments, the connecting frame may also be a connecting plate 14, a channel steel connector, a rectangular tube connector, a round tube connector, or an integral welded frame structure.

[0102] The installation of the connecting frame not only improves the structural rigidity, but also enhances the overall fatigue resistance of the support components, thus extending the service life of the equipment.

[0103] Example 5:

[0104] Based on Examples 3 and 4, this example further illustrates the installation relationship between the support structure and the loom frame device.

[0105] like Figures 1 to 3 As shown, the loom frame assembly includes a first wall plate 1, a second wall plate 2, a front lower support 3, and a rear lower support 4.

[0106] The first front support member 10 and the second front support member 16 are both spaced apart from the top surface of the front lower support 3.

[0107] The first rear support member 11 and the second rear support member 17 are both spaced apart from the top surface of the rear lower support 4.

[0108] Gaps are provided between the first front support member 10, the second front support member 16 and the front lower support 3, and between the first rear support member 11, the second rear support member 17 and the rear lower support 4. The purpose of this is to prevent the support members from forming rigid contact with the support. When a gap is maintained between the support member and the support, the vibration generated by the tie rod assembly 6 cannot be directly transmitted to the support through the support member, thereby ensuring the independence of the third load transmission path.

[0109] The aforementioned spacing structure prevents the support member from directly pressing against the support surface, thereby avoiding vibration being directly transmitted to the support through the support member.

[0110] Preferably, a gap of 2mm to 20mm is reserved between the support member and the top surface of the support, more preferably 5mm to 10mm.

[0111] This gap design ensures that even minor deformations during long-term operation will not cause the support to come into contact with the stop.

[0112] For ease of installation and positioning, the first front floor mount 9 and the second front floor mount 15 are configured to be detachably connected to the front lower support 3; the first rear floor mount 13 and the second rear floor mount 18 are configured to be detachably connected to the rear lower support 4; the first front floor mount 9 and the second front floor mount 15 are both disengaged from the front lower support 3 when the fixing device is in operation; the first rear floor mount 13 and the second rear floor mount 18 are both disengaged from the rear lower support 4 when the fixing device is in operation.

[0113] During installation, the first front floor mount 9 and the second front floor mount 15 are detachably connected to the outer side of the front lower support 3; the first rear floor mount 13 and the second rear floor mount 18 are detachably connected to the outer side of the rear lower support 4.

[0114] During the installation of the fixing device, the first front ground seat 9, the first rear ground seat 13, the second front ground seat 15, and the second rear ground seat 18 are first positioned in their predetermined installation locations, and the front lower support 3 and the rear lower support 4 are used as installation references for temporary positioning. Then, the connection between the support components and the tie rod assembly 6, as well as the installation of the sheathing machine 5 and the sheathing machine fixing assembly, are completed. After the overall position adjustment is completed, the temporary connecting parts between the ground seats and the supports are removed, detaching the ground support system from the loom frame device, allowing it to be supported only by the ground, thus forming an independent vibration transmission system.

[0115] For detachable connection structures, bolted connections are preferred.

[0116] During installation, the supports are used as positioning references to complete the installation and positioning of the support structure.

[0117] After installation is complete, remove the aforementioned connecting bolts.

[0118] After removal, the first front landing seat 9 and the second front landing seat 15 are disengaged from the front lower support 3; the first rear landing seat 13 and the second rear landing seat 18 are disengaged from the rear lower support 4.

[0119] At this point, the entire tie rod fixing support assembly is supported only by the ground and no longer forms a vibration transmission relationship with the loom frame device.

[0120] Therefore, the vibration load generated by the tie rod assembly 6 can be transmitted to the ground via the third load transmission path, without acting on the front lower support 3 and the rear lower support 4.

[0121] Through the above structure, the present invention realizes multi-path diversion and transmission of vibration loads of the sheathing machine and the tie rod, which greatly reduces the vibration level of the loom frame device, improves the stability of the loom at high speed, reduces equipment wear and noise, and improves fabric quality and equipment service life.

[0122] In this invention, the vibration load generated during the operation of the shedding mechanism is no longer concentrated and transmitted to the loom frame device along a single path, but is instead distributed through multiple load transmission paths. Specifically, a portion of the vibration load is transmitted to the loom frame device via the first connecting seat 7, the second connecting seat 8, and the first damping element 19 and the second damping element 20, thus forming a first load transmission path; a portion of the vibration load is directly transmitted to the ground via the first vibration guiding support 21 and the second vibration guiding support 22, thus forming a second load transmission path; and the vibration load generated during the operation of the tie rod assembly 6 is directly transmitted to the ground via the first and second grounding support units, thus forming a third load transmission path. Through the combined action of these three load transmission paths, the vibration load generated by the shedding mechanism is distributed between the loom frame device and the ground, reducing the concentration of vibration energy in the loom frame device and improving the vibration reduction effect and overall machine stability.

[0123] Practical applications show that, with the fixing device of this invention, the vibrations generated during the operation of the shedding mechanism can be diverted and transmitted through the loom frame device path and the ground path, reducing the dynamic load on the loom frame device structure. Compared with traditional installation methods, it can reduce the vibration response of the wall panels and supports, improve the operational stability of the shedding mechanism, reduce the risk of loosening of connectors and structural fatigue damage, and is conducive to improving the weaving quality under high-speed loom operation.

[0124] Example 6:

[0125] The present invention also provides a loom, including a loom frame assembly, a shedding mechanism, and a fixing device according to any of the above embodiments.

[0126] The loom frame assembly includes a first wall plate 1, a second wall plate 2, a front lower support 3, and a rear lower support 4; the shedding mechanism includes a shedding machine 5 and a pull rod assembly 6.

[0127] The shedding mechanism 5 is connected to the loom frame and the ground via a frame connection unit and a ground connection unit, respectively. The tie rod assembly 6 is connected to the ground via a tie rod fixing support assembly. During loom operation, the vibration load generated by the shedding mechanism is transmitted through the first load transmission path, the second load transmission path, and the third load transmission path, thereby reducing the vibration of the loom frame and improving the stability of the loom during high-speed operation.

[0128] This invention is particularly applicable to high-speed air-jet looms with rotation speeds above 800 rpm, and is also applicable to other looms that require reducing the impact of vibration on the shedding mechanism.

[0129] The invention has a simple and reasonable overall structure, is easy to install, and has a low manufacturing cost. It can be modified and applied based on the existing loom structure without major adjustments to the main structure of the loom, and has good engineering feasibility and promotional value.
