Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of textile technology, and more specifically, to a wide-width mesh loom with a connecting rod cam structure. Background Technology

[0002] Throughout the development of the textile industry, the application fields of mesh fabrics have been continuously expanding, from the traditional fields of clothing and home textiles to multiple professional fields such as industrial netting, construction safety netting, and agricultural insect netting. This has led to a continuous increase in market demand for wide-width mesh fabrics, because wide-width fabrics can not only improve production efficiency and reduce splicing processes, but also reduce production costs and improve the consistency of product quality.

[0003] Regarding the key motion mechanism of looms, traditional link-type beat-up looms have significant drawbacks. The gaps between the links result in short weft insertion time and weak beat-up force, poor stability at high speeds, and high energy consumption, making it difficult to meet the requirements of efficient and high-quality weaving. To improve this situation, cam beat-up technology has emerged. Cam beat-up eliminates the link gap problem, extends the weft insertion time, enhances beat-up force, maintains good stability at high speeds, and saves energy. However, cam beat-up technology also faced many technical bottlenecks in its early stages, such as the need to accurately simulate the complex beat-up motion curves in the design of the cam profile curve to ensure stable operation of the loom under different working conditions. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a wide-width mesh loom with a connecting rod cam structure, which solves the obvious drawbacks of traditional connecting rod weft-beating looms in the prior art. The gap between the connecting rods leads to short weft insertion time and weak weft-beating force. The loom has poor stability and high energy consumption when running at high speed, making it difficult to meet the technical problems of efficient and high-quality weaving requirements.

[0005] According to one aspect, at least one embodiment of this disclosure provides a wide-width wire mesh loom with a linkage cam structure, comprising:

[0006] A rotating disc, wherein a lifting frame is provided on one side of the rotating disc;

[0007] A fixed-frequency drive assembly is disposed between the rotary table and the lifting frame;

[0008] A sliding limit assembly is disposed on the lifting frame;

[0009] The fixed-frequency drive assembly includes a rotary gear fixedly attached to the side wall of the rotary disk. A fixed frame is provided on one side of the rotary disk, and a driven shaft is provided on the side wall of the fixed frame. A driven gear is fixedly mounted on the driven shaft, and the driven gear meshes with the rotary gear. A rotary cam is provided at the end of the driven shaft. A swing frame is connected to the side wall of the lifting frame, and a contact wheel is provided on the swing frame. The contact wheel contacts the rotary cam.

[0010] As a further technical solution, the side wall of the fixed frame is provided with a positioning shaft, the end of the positioning shaft is provided with a positioning plate, the positioning plate is provided with a plug tube, the swing frame has a limit port, and one end of the plug tube is inserted into the interior of the limit port.

[0011] As a further technical solution, the sliding limiting component includes a plug hole, which is opened on the side wall of the lifting frame. A connecting shaft is provided inside the plug hole, and a sliding groove is provided on the swing frame. One end of the connecting shaft is inserted into the sliding groove.

[0012] As a further technical solution, a reinforcing frame is provided on the side wall of the swing frame, and the reinforcing frame is located at the edge of the sliding slot.

[0013] As a further technical solution, the swing frame is provided with a wheel axle, and the contact wheel is fitted on the wheel axle.

[0014] As a further technical solution, the upper end face of the lifting frame is provided with a mounting plate, and the mounting plate has bolt connection holes, which are located on opposite sides of the upper end face of the mounting plate.

[0015] As a further technical solution, a locking cap is provided at the end of the passive shaft, and the locking cap is in contact with the rotating cam.

[0016] As a further technical solution, a reinforcing plate is provided on the side wall of the driven gear, and the reinforcing plate is in contact with the driven gear.

[0017] The beneficial effects of the embodiments disclosed herein are as follows:

[0018] In this disclosure, a wide-width mesh loom with a connecting cam structure effectively extends the weft insertion time due to its unique design. Compared with traditional connecting rod weft insertion looms, it can complete the weft insertion process within a more ample time, avoiding problems such as weft offset and missing weft caused by rushed weft insertion, thus significantly improving the weaving accuracy of the fabric. At the same time, the cam weft insertion technology gives the loom a stronger weft insertion force, making the warp and weft threads interweave tightly, improving the fabric's density and smoothness, and significantly improving the quality of the finished product. In addition, the wide-width weaving capability reduces the fabric splicing process, directly improving production efficiency and meeting the market's demand for efficient production of wide-width mesh fabrics.

[0030] like Figures 1-3 As shown, it illustrates a wide-width wire mesh loom with a linkage cam structure according to this disclosure, comprising:

[0031] Rotary turntable 1, with a lifting frame 2 installed on one side of rotary turntable 1;

[0032] Fixed-frequency drive component 3 is disposed between the rotary table 1 and the lifting frame 2;

[0033] Sliding limit component 4 is mounted on lifting frame 2;

[0034] The fixed-frequency drive assembly 3 includes a rotating gear 3-1, which is fixedly attached to the side wall of the rotary disk 1. A fixed frame 3-2 is provided on one side of the rotary disk 1. A driven shaft 3-3 is provided on the side wall of the fixed frame 3-2. A driven gear 3-4 is fixedly mounted on the driven shaft 3-3. The driven gear 3-4 meshes with the rotating gear 3-1. A rotating cam 3-5 is provided at the end of the driven shaft 3-3. A swing frame 3-6 is connected to the side wall of the lifting frame 2. A contact wheel 3-7 is provided on the swing frame 3-6. The contact wheel 3-7 is in contact with the rotating cam 3-5.

[0035] The sliding limit assembly 4 includes a plug hole 4-1, which is located on the side wall of the lifting frame 2. A connecting shaft 4-2 is provided inside the plug hole 4-1. A sliding groove 4-3 is provided on the swing frame 3-6. One end of the connecting shaft 4-2 is inserted into the sliding groove 4-3.

[0036] In some examples, the spindle 1 is placed smoothly in a predetermined position, ensuring that its mounting surface is flat and stable. As the core rotating component of the loom, the installation accuracy of the spindle 1 directly affects the overall operational stability of the loom. The installation position of the lifting frame 2 is determined on one side of the spindle 1. Appropriate connectors (such as bolts and nuts) are used to fix the lifting frame 2 to the foundation structure on which the spindle 1 is located. During the connection process, it is necessary to ensure that the relative position of the lifting frame 2 and the spindle 1 is accurate and that the lifting frame 2 itself remains vertical to ensure that the components subsequently installed on it can work normally. The rotating gear 3-1 is tightly fitted and fixed to the side wall of the spindle 1, ensuring that the rotating gear 3-1 and the mounting hole of the spindle 1 are precisely aligned. High-strength bolts are used for tightening to prevent the rotating gear 3-1 from loosening or shifting during the operation of the loom, which would affect the stability of power transmission.

[0037] Install a fixing bracket 3-2 on one side of the rotary disc 1, aligning it with the rotating gear 3-1. This ensures that the subsequently installed driven shaft 3-3 and driven gear 3-4 can mesh properly with the rotating gear 3-1. The fixing bracket 3-2 should be firmly fixed to the base structure, using welding or high-strength bolts, to ensure it does not wobble during loom operation. Install the driven shaft 3-3 on the side wall of the fixing bracket 3-2, allowing it to rotate freely. During installation, pay attention to the installation angle of the driven shaft 3-3, ensuring it is parallel to the axis of the rotating gear 3-1 for good meshing. Install suitable bearings at both ends of the driven shaft 3-3 to reduce frictional resistance during rotation. Finally, securely mount the driven gear 3-4 onto the driven shaft 3-3. Ensure a tight and reliable key connection between the driven gear 3-4 and the driven shaft 3-3, allowing the driven gear 3-4 to rotate synchronously with the driven shaft 3-3. Adjust the meshing clearance between the driven gear 3-4 and the rotating gear 3-1, generally by adjusting the position of the fixing bracket 3-2. The meshing clearance should be moderate; too large a clearance will lead to unstable transmission and tooth skipping; too small a clearance will increase gear wear and may even cause gear jamming. Install the rotating cam 3-5 at the end of the driven shaft 3-3, using a key connection and nut tightening to ensure a firm connection between the rotating cam 3-5 and the driven shaft 3-3. After installation, check whether the installation position of the rotating cam 3-5 is accurate, and its working surface should be smooth and free of defects to ensure good contact and normal operation with the contact wheel 3-7.

[0038] A swing frame 3-6 is connected to the side wall of the lifting frame 2. The connection method can be a pin connection, so that the swing frame 3-6 can swing flexibly around the pin. Adjust the position of the contact wheel 3-7 to maintain good contact with the working surface of the rotating cam 3-5. The contact pressure should be moderate. The contact pressure can be adjusted by setting a suitable elastic element (such as a spring) between the contact wheel 3-7 and the swing frame 3-6. Generally, the contact pressure should be adjusted according to the working load of the loom and the profile curve of the cam to ensure that the contact wheel 3-7 can always closely follow the movement of the rotating cam 3-5 during the operation of the loom and accurately transmit power. An insertion hole 4-1 is opened on the side wall of the lifting frame 2. The connecting shaft 4-2 is inserted into the insertion hole 4-1 to ensure that the connecting shaft 4-2 can slide freely in the insertion hole 4-1. The length of the connecting shaft 4-2 should be selected according to the actual installation requirements to ensure that one end can be smoothly inserted into the sliding slot 4-3 on the swing frame 3-6.

[0039] like Figures 1-3 As shown in the figure, this embodiment proposes that the side wall of the fixed frame 3-2 is provided with a positioning shaft 3-8, the end of the positioning shaft 3-8 is provided with a positioning plate 3-9, the positioning plate 3-9 is provided with a plug tube 3-10, the swing frame 3-6 is provided with a limit port 3-11, and one end of the plug tube 3-10 is inserted into the interior of the limit port 3-11.

[0040] In some examples, a positioning shaft 3-8 is installed on the side wall of the fixed frame 3-2, allowing the end of the positioning shaft 3-8 to extend out. A positioning plate 3-9 is installed at the end of the positioning shaft 3-8, ensuring a firm connection between the positioning plate 3-9 and the positioning shaft 3-8. A insertion tube 3-10 is provided on the positioning plate 3-9, and one end of the insertion tube 3-10 is inserted into the limiting port 3-11 opened on the swing frame 3-6. The fit between the insertion tube 3-10 and the limiting port 3-11 should be tight to provide a good limiting effect, restrict the swing range of the swing frame 3-6, and ensure the motion accuracy of the loom during operation.

[0041] For example, such as Figure 1 As shown, a reinforcing frame 4-4 is provided on the side wall of the swing frame 3-6, and the reinforcing frame 4-4 is placed at the edge of the sliding groove 4-3.

[0042] In some examples, one end of the connecting shaft 4-2 is inserted into the sliding slot 4-3 on the swing frame 3-6, and the position of the swing frame 3-6 is adjusted so that the connecting shaft 4-2 slides smoothly and without obstruction in the sliding slot 4-3. At the same time, a reinforcing frame 4-4 is installed on the side wall of the swing frame 3-6 at the edge of the sliding slot 4-3. The reinforcing frame 4-4 is fixed to the swing frame 3-6 by welding or bolting to enhance the structural strength of the swing frame 3-6 at this part and prevent the sliding slot 4-3 from deforming due to stress during the operation of the loom, which would affect the normal operation of the connecting shaft 4-2.

[0043] For example, such as Figure 1 As shown, the swing frame 3-6 is equipped with a wheel axle 5, and the contact wheel 3-7 is mounted on the wheel axle 5.

[0044] In some examples, the axle 5 is installed on the swing frame 3-6, and then the contact wheel 3-7 is fitted onto the axle 5 to ensure that the contact wheel 3-7 can rotate freely.

[0045] For example, such as Figure 3 As shown, the upper end face of the lifting frame 2 is provided with a mounting plate 6, and the mounting plate 6 has bolt connection holes 7, which are located on opposite sides of the upper end face of the mounting plate 6.

[0046] In some examples, a mounting plate 6 is installed on the upper surface of the lifting frame 2 and bolts are used to fix the mounting plate 6 to the lifting frame 2. Bolt connection holes 7 are opened on opposite sides of the upper surface of the mounting plate 6. These bolt connection holes 7 can be used to connect with other related components, such as installing some auxiliary equipment or further expanding the overall structure.

[0047] For example, such as Figure 1 As shown, a locking cap 8 is provided at the end of the passive shaft 3-3, and the locking cap 8 is in contact with the rotating cam 3-5.

[0048] In some examples, a locking cap 8 is installed at the end of the driven shaft 3-3 and tightened to make it in close contact with the rotating cam 3-5. The function of the locking cap 8 is to prevent the rotating cam 3-5 from having axial displacement on the driven shaft 3-3, and to ensure that the rotating cam 3-5 can work stably.

[0049] For example, such as Figure 1 As shown, a reinforcing plate 9 is provided on the side wall of the driven gear 3-4, and the reinforcing plate 9 is in contact with the driven gear 3-4.

[0050] In some examples, a reinforcing plate 9 is installed on the side wall of the driven gear 3-4, so that the reinforcing plate 9 fits tightly with the driven gear 3-4. The reinforcing plate 9 can be fixed to the driven gear 3-4 by welding or bolting. Its function is to enhance the structural strength of the driven gear 3-4, improve its load-bearing capacity during operation, and prevent the driven gear 3-4 from being damaged due to excessive force. When installing the reinforcing plate 9, it is necessary to ensure that the installation position of the reinforcing plate 9 is accurate, that it fits tightly with the driven gear 3-4, and that the welding or bolting connection is firm and reliable.

[0051] In use, during the operation of a wide-width mesh loom with a connecting rod cam structure, the power transmission and motion conversion mechanism is the core to ensure the normal operation of the loom. After the loom's power source (such as an electric motor) is started, it drives the self-rotating disc 1 to start rotating. The self-rotating disc 1 is the starting component for power transmission, and the rotating gear 3-1, which is tightly fitted and fixed on one side of it, also rotates synchronously.

[0052] The rotating gear 3-1 meshes with the driven gear 3-4 on the driven shaft 3-3 on the side wall of the fixed frame 3-2. Through gear transmission, the rotational power of the turntable 1 is stably transmitted to the driven shaft 3-3. This gear transmission not only ensures the stability of power transmission, but also allows for precise control of the rotational speed by adjusting the gear ratio. After the driven shaft 3-3 receives power, it drives the rotating cam 3-5 at its end to rotate together. When the driven gear 3-4 drives the reinforcing plate 9 to rotate, the fixed frame 3-2 is fixed and does not rotate with the driven gear 3-4. The rotation of the rotating cam 3-5 is the key to the motion conversion of the entire loom.

[0053] During the rotation of the rotary cam 3-5, its unique profile curve plays a role. When the cam rotates, the profile curve continuously contacts the contact wheel 3-7 on the swing frame 3-6 and generates an interaction force. The contact wheel 3-7 is mounted on the wheel axle 5 and can rotate freely, reducing friction with the cam surface. Driven by the cam profile curve, the contact wheel 3-7 drives the swing frame 3-6 to reciprocate around the fulcrum (such as the pin) connected to the lifting frame 2.

[0054] The reciprocating swing of the swing frame 3-6 is converted into the vertical linear motion of the lifting frame 2 through the sliding limit component 4. Specifically, the swing frame 3-6 is provided with a sliding groove 4-3. One end of the connecting shaft 4-2 in the insertion hole 4-1 on the side wall of the lifting frame 2 is inserted into the sliding groove 4-3. When the swing frame 3-6 swings, the connecting shaft 4-2 slides in the sliding groove 4-3. Since the other end of the connecting shaft 4-2 is fixed on the lifting frame 2, it drives the lifting frame 2 to make a stable vertical linear motion.

[0055] In this process, the positioning system consisting of positioning shaft 3-8, positioning disk 3-9 and insertion pipe 3-10, as well as sliding limit assembly 4, jointly ensure the accuracy and stability of the movement. Positioning disk 3-9 is installed at the end of positioning shaft 3-8 on the side wall of fixed frame 3-2. Insertion pipe 3-10 on positioning disk 3-9 is inserted into limit port 3-11 of swing frame 3-6 to limit the swing range of swing frame 3-6, so that it can only move within the specified trajectory. The cooperation between linkage shaft 4-2 and sliding slot 4-3 in sliding limit assembly 4 further constrains the movement trajectory of lifting frame 2, preventing it from deviating or shaking during up and down movement.

[0056] Based on the above motion principle, by rationally designing the contour curve of the rotary cam 3-5, the structural parameters of the swing frame 3-6, and the coordination relationship of each component, the loom can achieve a large-amplitude reciprocating motion to meet the weaving requirements of wide-width mesh fabrics. The mounting plate 6 on the upper end of the lifting frame 2 is provided with bolt connection holes 7, which can install multiple heald frames or other weaving components to realize the coordinated movement of multiple sets of warp threads, thereby completing the entire weaving process of wide-width mesh fabrics from warp opening and weft introduction to interlacing.
