[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.

[0023] The following is combined with Figure 1-6 This application is described in further detail.

[0024] The present application embodiment discloses a fabric flattening and tentering processing device. Figure 1-6 The fabric flattening and tentering processing device includes two groups of brackets 1 arranged along the textile transmission direction, and mounting plates 2 are installed on the two groups of brackets 1. The two mounting plates 2 are respectively located on both sides of the textile transmission direction. Two horizontal rotating shafts 3 are installed between the two mounting plates 2. Sprocket wheels 31 are installed on the two horizontal rotating shafts 3. The two sprocket wheels 31 are connected by a chain 32. A first motor 33 that drives the horizontal rotating shaft 3 to rotate is provided on one of the mounting plates 2.

[0025] A plurality of first clamping members 4 are arranged on one side of the chain 32 along the textile transport direction, and a plurality of second clamping members 5 used in conjunction with the first clamping members 4 are arranged on the other side of the chain 32 .

[0026] Specifically, the first clamping member 4 includes a fixed plate 41 connected to two adjacent pins in the chain 32, a sliding cylinder 42 is installed on the side of the fixed plate 41 away from the chain 32, a sliding rod 43 is passed through the side of the sliding cylinder 42 away from the chain 32, a sliding groove 421 is provided at the bottom of the sliding cylinder 42, and a pulley 44 passing through the inside of the sliding groove 421 is provided at the bottom of the sliding rod 43; a vertical rod 45 is fixedly connected to the sliding rod 43, and a cloth clip 46 for clamping the edge of the textile is provided on the vertical rod 45.

[0027] A first guide rail 6 used in conjunction with the first clamping member 4 and a second guide rail 7 used in conjunction with the second clamping member 5 are installed between the two mounting plates 2. The second guide rail 7 has the same structure as the first guide rail 6. Figure 3 The first guide rail 6 and the second guide rail 7 can be installed between two mounting plates 2 through a connecting plate, wherein a notch can be provided on the mounting plate 2.

[0028] The first guide rail 6 is annular, and is spaced apart on the two horizontal rotating shafts 3, and is in sliding contact with the pulley 44 on the first clamping member 4; when the sprocket 31 rotates, the drive chain 32 and the first clamping member 4 move along the first guide rail 6; at the textile feeding end, the spacing between the first guide rail 6 and the second guide rail 7 is smaller than the corresponding spacing at the textile discharging end.

[0029] During the transmission process, the edges of the textile are clamped by the first clamping member 4 and the second clamping member 5. When the first motor 33 is started, it drives the horizontal shaft 3 to rotate, thereby driving the chain 32 and the first clamping member 4 connected to the chain 32 to move along the first guide rail 6, and the second clamping member 5 to move along the second guide rail 7; the pulley 44 at the bottom of the first clamping member 4 moves to the side away from the chain 32 while sliding along the first guide rail 6, and the pulley 44 at the bottom of the second clamping member 5 moves to the side away from the chain 32 while sliding along the second guide rail 7, that is, the first clamping member 4 and the second clamping member 5 move away from each other, and the width of the textile is gradually increased during the stretching process.

[0030] Through the cooperation of the first clamping member 4 and the second clamping member 5, the processing device can effectively clamp the textile, so that it remains stable during the transmission process, reduce wrinkles and curling, and thus improve the overall flatness of the textile. The horizontal shaft 3 is driven to rotate by the first motor 33, driving the chain 32 and the clamping member to move along the guide rail. This design allows the textile to be subjected to uniform force during the stretching process, thereby enhancing the stability of the processing process. In addition, during the stretching process, the width of the textile gradually increases, and it can be shaped by heat treatment and other means, which not only improves the dimensional accuracy of the textile, but also improves its appearance and performance.

[0031] The processing device can adapt to textiles of different widths and materials, making it highly flexible and applicable in the actual textile processing process. The automated stentering process improves production efficiency, reduces the need for manual operation, and also reduces labor intensity. In the subsequent processing process, open-width singeing can also be performed. Compared with traditional cylindrical singeing, open-width singeing is cleaner and more thorough, reducing energy consumption.

[0032] In some embodiments of the present invention, an upper opening 451 is provided on the upper end surface of the vertical rod 45, and a movable rod 452 that can slide up and down is installed in the upper opening 451. An annular guide portion is provided on the mounting plate 2, and a horizontally extending round rod 453 is provided on the side of the movable rod 452 facing the mounting plate 2. The round rod 453 extends into the interior of the annular guide portion and can move inside.

[0033] When the first clamping member 4 moves, it can drive the round rod 453 to move along the annular guide portion through the moving rod 452. Such a structure strengthens the stability of the first clamping member 4 relative to the mounting plate 2, thereby significantly improving the accuracy and effect of the textile processing process.

[0034] In some embodiments of the present invention, the annular guide portion is a guide slide 21 and passes through the mounting plate 2, thereby dividing the mounting plate 2 into a central area and a peripheral edge, and the bracket 1 is used to connect and fix the central area of ​​the mounting plate 2 with the peripheral edge.

[0035] This solution not only ensures that the guide slide 21 is a continuous closed-loop channel, but also enhances the overall structural stability of the mounting plate 2 through the reinforcement effect of the bracket 1. This structural arrangement not only ensures the smooth sliding of the moving rod 452 and the round rod 453 in the annular guide portion, but also improves the reliability and accuracy of the entire device during the textile processing process.

[0036] The bracket 1 is provided with an escape opening 11 for the round rod 453 to pass through. By providing the escape opening 11 on the bracket 1, the round rod 453 has a larger activity area when sliding along the guide slideway 21, so that its use effect is better.

[0037] In some embodiments, the cloth clip 46 is composed of a bottom clip 461 and a top clip 462, wherein the bottom clip 461 is installed on the side wall of the vertical rod 45; a side opening 454 connected to the upper opening 451 is opened on the side wall of the vertical rod 45, and the movable rod 452 is rotatably connected to the hinge rod 455 through the side opening 454; a waist-shaped hole 456 is opened on the vertical rod 45, and the hinge rod 455 is inserted into the waist-shaped hole 456.

[0038] A gear 457 is fixedly sleeved on the hinge rod 455, and a rack 458 meshing with the gear 457 is fixedly connected to the vertical rod 45; a feed end inclined surface 211 is provided in the section of the guide slide 21 adjacent to the textile feed end, and a discharge end inclined surface 212 is provided in the section at the textile discharge end. The feed end inclined surface 211 is inclined upward in the textile feeding direction, and the discharge end inclined surface 212 is inclined upward in the textile discharge direction, and a straight surface 213 is formed between the feed end inclined surface 211 and the discharge end inclined surface 212.

[0039] When the round rod 453 is located at the flat surface 213, the top clamp 462 and the bottom clamp 461 are tightly closed to clamp the textile; when the round rod 453 moves from the inclined surface 211 of the feed end to the flat surface 213, the angle between the top clamp 462 and the bottom clamp 461 gradually decreases; when the round rod 453 moves from the flat surface 213 to the inclined surface 212 of the discharge end, the angle between the top clamp 462 and the bottom clamp 461 gradually increases, so that the textile clamped therebetween can be relaxed and released.

[0040] When the round rod 453 slides to the area outside the flat surface 213, the feed end inclined surface 211, and the discharge end inclined surface 212, the angle between the top clamp 462 and the bottom clamp 461 is maximized; when the round rod 453 moves from the feed end inclined surface 211 to the flat surface 213, the height of the round rod 453 in the vertical direction gradually decreases. At this time, the round rod 453 drives the moving rod 452 to press down. When the moving rod 452 is pressed down, the gear 457 rotates along the rack 458. At this time, the hinged rod 455 rotates, so that the angle between the top clamp 462 and the bottom clamp 461 gradually decreases, and the textile is clamped; when the round rod 453 slides along the flat surface 213, the top clamp 462 and the bottom clamp 461 are tightly closed to clamp the textile.

[0041] When the round rod 453 moves from the inclined surface 212 at the discharge end to the side away from the flat surface 213, the round rod 453 gradually increases in height in the vertical direction. At this time, the round rod 453 drives the moving rod 452 to move upward. When the moving rod 452 moves upward, the gear 457 rotates along the rack 458. At this time, the hinged rod 455 rotates, so that the angle between the top clip 462 and the bottom clip 461 gradually increases, thereby loosening and releasing the textile.

[0042] In some embodiments, two inclined surfaces 211 at the feed end are provided, respectively located at the upper and lower parts of the horizontal rotating shaft 3, and horizontally symmetrical along the axis of the horizontal rotating shaft 3; two inclined surfaces 212 at the discharge end are provided, respectively located at the upper and lower parts of the horizontal rotating shaft 3, and horizontally symmetrical along the axis of the horizontal rotating shaft 3.

[0043] See attached Figure 3 The feed end inclined surface 211 and the discharge end inclined surface 212 may be provided in pairs, and symmetrically arranged along the plane where the axis connecting line of the two horizontal rotating shafts 3 is located.

[0044] The user can also arrange a group of textiles on the upper and lower parts of the chain 32 respectively to complete the stretching process of the two groups of textiles. The transmission directions of the two groups of textiles are opposite, and the discharging rack and the receiving rack can be set according to the actual situation.

[0045] The first guide rail 6 has a feed straight section, an involute section, and a discharge straight section; the second guide rail 7 also has a feed straight section, an involute section, and a discharge straight section arranged corresponding to the first guide rail 6; the two feed straight sections have the same spacing; the two discharge straight sections have the same spacing; at the textile feed end, the spacing between the two involute sections is smaller than the corresponding spacing at the textile discharge end.

[0046] Since a feed straight section and a discharge straight section are formed on the first guide rail 6 and the second guide rail 7, when the first clamping member 4 and the second clamping member 5 slide on the feed straight section and the discharge straight section, they only move along the length direction of the textile and do not move in the width direction of the textile. They maintain their structural stability and are convenient for cooperating with the feed end and the discharge end of the textile.

[0047] Furthermore, when the feed straight section is projected onto the mounting plate 2 in the horizontal direction, the resulting projection is located at the portion of the feed inclined surface away from the straight surface 213; that is, by using the feed straight section in conjunction with the guide slide 21, the first clamping member 4 and the second clamping member 5 can move synchronously with the textile before clamping the textile, and then clamp the textile, making the clamping work simpler and avoiding unstable clamping due to uneven edges when feeding or discharging the textile.

[0048] In some embodiments of the present invention, a textile placement rack for supporting textiles is also installed between the two mounting plates 2 .

[0049] The textile placement rack is provided to facilitate placement of the textiles, so that the textiles are more flat and the chain 32 is prevented from causing adverse effects thereon.

[0050] In some embodiments of the present invention, a feeding mechanism 8 is provided at the feeding end of the textile, a pretreatment mechanism 9 is provided between the feeding mechanism 8 and the support 1, and a drying mechanism 10 for drying the textile is provided on the support 1.

[0051] By setting up the feeding mechanism 8, it is convenient to place the cloth rolls for processing and to discharge the cloth rolls; by setting up the pretreatment mechanism 9, it is convenient to pretreat the textiles, such as wet water treatment or padding treatment, etc.; wherein the pretreatment mechanism 9 may be provided with a guide roller to allow the textiles to smoothly enter the upper part of the bottom clip 461 of the first clamping member 4 and the second clamping member 5. By setting up the drying mechanism 10, the textiles after stenting can be dried to make the finished textiles more stable and convenient to be rolled into finished cloth rolls later.

[0052] The implementation principle of a fabric flattening and tentering processing device in the embodiment of the present application is:

[0053] Through the cooperation of the first clamping member 4 and the second clamping member 5, the processing device can effectively clamp the textile, so that it remains stable during the transmission process, reduces wrinkles and curling, and thus improves the overall flatness of the textile. The horizontal shaft 3 is driven to rotate by the first motor 33, driving the chain 32 and the clamping member to move along the guide rail. This design allows the textile to be subjected to uniform force during the stretching process, thereby enhancing the stability of the processing process.

[0054] The first guide rail 6 and the second guide rail 7 cooperate with the first clamping member 4 and the second clamping member 5 respectively to guide the clamping members. The pulley 44 on the first clamping member 4 and the pulley 44 on the second clamping member 5 gradually expand with the transportation of the textile, so that the distance between the cloth clip 46 of the first clamping member 4 and the cloth clip 46 on the second clamping member 5 increases, completing the tentering process of the textile.

[0055] The first guide rail 6 and the second guide rail 7 are both annular, sleeved on the horizontal shaft 3, and in sliding contact with the pulley 44 on the first clamping member 4. When the sprocket 31 rotates, the drive chain 32 and the first clamping member 4 move along the first guide rail 6.

[0056] When the round rod 453 is located at the flat surface 213, the top clamp 462 and the bottom clamp 461 are tightly closed to clamp the textile. When the round rod 453 moves from the feed end inclined surface 211 to the flat surface 213, or from the flat surface 213 to the discharge end inclined surface 212, the angle between the top clamp 462 and the bottom clamp 461 gradually expands, so that the textile clamped therebetween can be relaxed and released. In this way, the textile can be stretched smoothly and the damage to the textile caused by clamping too tightly can be avoided.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
