Description

Technical Field

[0001] This invention relates to the field of weaving technology, and in particular to an automated weaving equipment for decorative fabrics and its weaving process. Background Technology

[0002] Decorative fabric is a type of textile material used for home and interior decoration. It typically comes in a rich variety of colors, patterns, and textures, used to decorate and beautify spaces in interior environments. Different materials can be chosen to suit different design styles and personal preferences, such as pure cotton, silk, linen, and polyester. Decorative fabric requires weaving equipment during production.

[0003] Chinese Patent No. CN215051037U discloses a weft-beating device for textile manufacturing. When beating the weft, it is equipped with a rotating device, a transmission device, and a connecting device. The rotating device can drive the connecting device to move through the transmission device, which in turn drives the beating plate with warp grooves to move and beat the weft, thus achieving the purpose of beating the weft.

[0004] However, in actual use, as the number of weft threads increases, the distance traveled by the weft insertion plate each time it moves will decrease accordingly. This means that the distance traveled by the weft insertion plate each time needs to be precisely calculated and integrated into the control module, which requires a high level of technology. Furthermore, it is only suitable for weft insertion of weft threads of corresponding thickness, and its application range is relatively limited. Summary of the Invention

[0005] To address the problems existing in the background technology, an automated decorative fabric weaving device and its weaving process are proposed. By incorporating a weft-beating drive component and an elastic connecting component, the weft-beating plate can be driven to move intermittently back and forth. During the intervals, the weft yarns are threaded through the warp yarns and arranged. After threading, the weft-beating plate is ready for the next round of weft-beating operations. Furthermore, in conjunction with the elastic connecting component, it can compensate for displacement differences during the weft-beating process as the length of the woven fabric changes, eliminating the need for adjustments to the displacement distance each time.

[0006] This invention proposes an automated weaving equipment for decorative fabrics, comprising a weaving machine body and a weft-beating device. The weft-beating device is mounted on the weaving machine body and includes:

[0007] The weft bending frame has a fixed frame on one side, which has multiple sets of through holes for the warp threads to pass through, and is used to press the weft threads.

[0008] The mounting frame is set on the side of the weft beating frame away from the fixed frame, and sliding limiters are provided on both sides to limit its movement trajectory.

[0009] The flexible connection components are located at the four corners of the mounting frame to connect the weft beating frame and the mounting frame, and to provide step compensation for the weft beating distance.

[0010] The weft insertion drive assembly is mounted on a fixed frame and includes a continuous drive mechanism, an intermittent conversion mechanism, and a reciprocating weft insertion mechanism. The three work together to drive the weft insertion frame to move back and forth to perform the weft insertion operation.

[0011] Preferably, the sliding limiting component includes a mounting frame vertically mounted on the weaving machine body, a limiting block slidably mounted on the mounting frame, and the limiting block being connected to the mounting frame.

[0012] Preferably, the elastic connection assembly includes a receiving cylinder connected to the mounting frame, a slider slidably disposed on its inner side, an elastic tension member disposed between the slider and its inner wall, and a connecting post connected to the slider for connection with the weft bead frame.

[0013] Preferably, the reciprocating beat-up mechanism includes:

[0014] The output shaft is rotatably mounted at the bottom of the fixed frame, and gear a is connected to its middle section.

[0015] Linkage a, one end of which is connected to the bottom end of the output shaft;

[0016] Linkage b has one end rotatably connected to the end of link a that faces away from the output shaft, and the other end rotatably connected to the top of the mounting frame.

[0017] Preferably, the intermittent switching mechanism includes a switching shaft that is rotatably mounted on a fixed frame, with its bottom end connected to a gear disc that meshes with gear a.

[0018] Preferably, the continuous drive mechanism includes:

[0019] The drive motor is mounted at the bottom of the mounting frame, and its output end passes through the mounting frame and is connected to a dial.

[0020] A convex locking arc is installed on the upper surface of the dial, and a notch is provided on one side of it;

[0021] A cylindrical pin is installed on the dial at the notch side of the convex locking arc;

[0022] The grooved wheel is installed at the top of the conversion shaft. Four sets of concave locking arcs that cooperate with the convex locking arcs are circumferentially spaced on its outer side. A radial groove that cooperates with the cylindrical pin is opened between two adjacent sets of concave locking arcs.

[0023] Preferably, the transmission ratio between the gear disc and gear a is 1:4, and the transmission ratio between the dial and the grooved wheel is 4:1.

[0024] This invention also proposes a weaving process for the aforementioned automated decorative fabric weaving equipment, specifically including the following steps:

[0025] S1. The warp exchange plate of the weaving machine is misaligned to form the gap through which the weft yarn passes. After the weft yarn passes through, the weft-beating operation is performed on it.

[0026] S2. Start the drive motor. The drive motor drives the transmission shaft to rotate intermittently by 90 degrees through the cooperation of the dial and the slotted wheel.

[0027] S3. When the transmission shaft is in intermittent transmission, the output shaft is driven to rotate intermittently through the cooperation of the gear disc and gears;

[0028] S4. The output shaft drives the mounting frame through connecting rods a and b to intermittently reciprocate and beat the weft.

[0029] S5. During the weft insertion process, the weft insertion frame uses elastic connecting components to perform step compensation for the weft insertion distance.

[0030] Through the above technical solution, namely the weaving equipment disclosed in this invention, by setting up a weft-beating drive component and an elastic connecting component, the weft-beating plate can be driven to move intermittently back and forth. During the intermittent process, the weft yarn is passed through the warp yarn and arranged. After passing through, the weft-beating plate is ready to perform the next round of moving weft-beating operation. The whole process realizes automated weft-beating operation. In addition, with the cooperation of the elastic connecting component, as the length of the woven fabric changes, the displacement difference during the weft-beating process can be compensated, eliminating the need to adjust the displacement distance each time and improving the convenience of equipment control.

[0031] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0040] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0041] like Figure 1 As shown, the present invention proposes an automated weaving equipment for decorative fabrics, comprising a weaving machine body and a weft-beating device. The weft-beating device is mounted on the weaving machine body and includes a weft-beating frame 1, a mounting frame 2, an elastic connecting component, and a weft-beating drive component. A fixed frame 3 is provided on one side of the weft-beating frame 1, and multiple sets of through holes for the warp threads to pass through, for pressing the weft threads. The mounting frame 2 is located on the side of the weft-beating frame 1 away from the fixed frame 3, and sliding limiters are provided on both sides to limit its movement trajectory. The elastic connecting component is located at the four corners of the mounting frame 2, for connecting the weft-beating frame 1 and the mounting frame 2, and for step compensation of the weft-beating distance. The weft-beating drive component is mounted on the fixed frame 3 and includes a continuous drive mechanism, an intermittent conversion mechanism, and a reciprocating weft-beating mechanism, which cooperate to drive the weft-beating frame 1 to move back and forth to perform the weft-beating operation.

[0042] like Figure 1 and Figure 2 As shown, the weaving machine includes a frame 4. The top and bottom of one end of the frame 4 are respectively connected to a guide shaft a5 and a roll a6, and the top and bottom of the other end are respectively connected to a guide shaft b7 and a roll b8. The roll b8 is used to roll up the woven decorative fabric, and the roll a6 is used to roll up the woven warp threads. Both the roll a6 and the roll b8 are equipped with anti-rotation blocks to prevent them from rotating.

[0043] like Figure 3As shown, two sets of guide frames 9 are provided on both sides of the inner middle of the frame 4. A warp exchange plate 10 is slidably arranged between each pair of guide frames 9. The two sets of warp exchange plates 10 are staggered. A rack 11 is provided on the opposite side of each set. A linkage shaft 12 is rotatably arranged on the inner wall of the frame 4 between the two sets of warp exchange plates 10. One end of the linkage shaft 12 passes through the frame 4 and is connected to an adjustment component. A gear b13 is provided in the middle of the linkage shaft 12. The gear b13 is meshed with both sets of racks 11.

[0044] like Figure 7 As shown, the adjustment assembly includes an adjustment frame 14, an adjustment motor 15, a worm gear 16, and a turbine 17. The adjustment frame 14 is installed on the side of the frame 4, the adjustment motor 15 is installed at the end of the adjustment frame 14, the output end of the adjustment motor 15 is connected to the worm gear 16 located inside the adjustment frame 14, and the turbine 17 is meshed on the lower side of the worm gear 16. The turbine 17 is installed on the linkage shaft 12.

[0045] During use, when it is necessary to misalign the two rows of warp threads, the worm gear 16 is rotated by adjusting the motor 15. During the rotation of the worm gear 16, it meshes with the turbine 17. The meshing force drives the linkage shaft 12 to rotate. When the linkage shaft 12 rotates, it acts on the rack 11 through the gear b13, thereby driving the warp exchange plates 10 on both sides to move up and down respectively. During the up and down movement, a gap is generated between the two rows of warp threads for the weft threads to pass through. During the pressing of the weft threads, the worm gear 16 and the turbine 17 have a self-locking function, which can limit the two sets of warp exchange plates 10 and improve their positional stability.

[0046] like Figure 4 As shown, the sliding limiter includes a mounting frame 18 vertically mounted on the weaving machine body, a limit block 19 slidably mounted on the mounting frame 18, and the limit block 19 is connected to the mounting frame 2.

[0047] During use, when the mounting frame 2 is subjected to force, it will cause the limiting block 19 to move on the mounting bracket 18, ensuring the stability of its movement.

[0048] like Figure 6 As shown, the elastic connection assembly includes a receiving cylinder 20 connected to the mounting frame 2, a slider 21 slidably disposed on its inner side, an elastic tension member 22 disposed between the slider 21 and its inner wall, and a connecting post 23 connected to the slider 21 for connecting with the weft bead frame 1.

[0049] During use, when the mounting frame 2 moves under the action of the weft insertion drive assembly, it will drive the weft insertion frame 1 to move synchronously. During the movement, the side of the weft insertion frame 1 presses the weft thread passing through the warp thread. As the fabric is woven, its weft insertion range will shrink. When the weft insertion frame 1 moves the same distance under the action of the weft insertion frame, the side of the weft insertion frame 1 will be subjected to the reverse pressure of the fabric. Under the action of the force, the weft insertion frame 1 will move relative to the mounting frame 2, and drive the slider 21 to squeeze the elastic tension member 22 through the connecting column 23, thereby compensating for the displacement difference during the weft insertion process. It is not necessary to adjust the displacement distance each time. The elastic tension member 22 is a tension spring.

[0050] like Figure 1 As shown, the reciprocating beat-up mechanism includes: an output shaft 24, which is rotatably mounted at the bottom of the fixed frame 3, with a gear a25 connected in the middle; a connecting rod a26, one end of which is connected to the bottom end of the output shaft 24; and a connecting rod b27, one end of which is rotatably connected to the end of the lower end face of the connecting rod a26 that is away from the output shaft 24, and the other end of which is rotatably connected to the top of the mounting frame 2.

[0051] like Figure 5 As shown, the intermittent conversion mechanism includes a conversion shaft 28 that is rotatably mounted on the fixed frame 3, and a gear disk 29 that meshes with the gear a25 at its bottom end.

[0052] like Figure 5 As shown, the continuous drive mechanism includes: a drive motor 30, which is installed at the bottom of the fixed frame 3, and its output end passes through the fixed frame 3 and is connected to a dial 31; a convex locking arc 32, which is installed on the upper surface of the dial 31, and has a notch on one side; a cylindrical pin 33, which is installed on the dial 31 and located on the notch side of the convex locking arc 32; and a grooved wheel 34, which is installed at the top of the conversion shaft 28, and has four sets of concave locking arcs 35 that are circumferentially spaced and cooperate with the convex locking arc 32 on its outer side, and a radial groove 36 that cooperates with the cylindrical pin 33 is provided between two adjacent sets of concave locking arcs 35.

[0053] Furthermore, the transmission ratio between the gear 29 and the gear a25 is 1:4, and the transmission ratio between the dial 31 and the grooved wheel 34 is 4:1.

[0054] Furthermore, a control box 37 is installed on the outside of the frame 4, and the drive motor 30 and the regulating motor 15 are both connected to the control module inside the control box 37.

[0055] The working principle of this invention is as follows: When the two sets of warp control plates are in a vertically misaligned state under the action of the adjustment component, they will drive the two rows of warp threads to be vertically misaligned one by one to form a gap. The shuttle (not shown) drives the weft thread through the gap to weave. During the process, the drive motor 30 drives the dial 31 to rotate. When the dial 31 rotates one revolution, it is guided into the radial groove 36 through the cylindrical pin 33. The drive groove wheel 34 drives the conversion shaft 28 and the gear disk 29 to rotate intermittently one-quarter revolution. Since the transmission ratio of the gear disk 29 and the gear a25 is 1:4, it will drive the gear a25 to drive the output shaft 24 to rotate one revolution. During the rotation of the output shaft 24, it will drive the connecting rod a26 to move synchronously. The connecting rod a26 and the connecting rod b27 The connection point makes a circular motion, and the connecting rod b27 drives the mounting frame 2 to move towards the weaving direction under the action of the sliding limit member and then reset. Therefore, under the continuous driving action of the drive motor 30, the mounting frame 2 and the weft insertion frame 1 will move intermittently back and forth. The weft insertion frame 1 will press the weft yarn as it moves. As the fabric is woven, its weft insertion range will shrink. When the weft insertion frame 1 moves the same distance under the action of the weft insertion frame, the side of the weft insertion frame 1 will be subjected to the reverse pressure of the fabric. Under the action of the force, the weft insertion frame 1 will move relative to the mounting frame 2 and drive the slider 21 to squeeze the elastic tension member 22 through the connecting column 23, thereby compensating for the displacement difference in the weft insertion process and eliminating the need to adjust the displacement distance each time.

[0056] In some embodiments, the present invention also provides a weaving process for an automated decorative fabric weaving device, specifically including the following steps:

[0057] S1. The warp exchange plate 10 of the weaving machine body controls the misalignment and exchange to form the gap through which the weft passes. After the weft passes through, the weft is beaten up.

[0058] S2. Start the drive motor 30. The drive motor 30 drives the transmission shaft to rotate intermittently by 90 degrees through the dial 31 and the slotted wheel 34.

[0059] S3. When the transmission shaft is in intermittent transmission, the output shaft 24 is driven to rotate intermittently through the gear disk 29 and the gear.

[0060] S4, the output shaft 24 drives the mounting frame 2 to intermittently reciprocate and move the weft-beating frame 1 through the connection a26 and the connection b27 to beat the weft;

[0061] S5 and weft insertion frame 1 use elastic connecting components to perform step compensation for the weft insertion distance during the weft insertion process.

[0062] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
