Description

Technical Field

[0001] The present invention relates to the technical field of heat setting of knitted fabrics, and particularly to a hot air slitting and setting device. Background Art

[0002] In the fabric processing process of the textile printing and dyeing industry, slitting and setting, as key processes, play a decisive role in the quality of the final product. With the continuous improvement of consumers' requirements for the quality of textiles and the development of the textile industry towards refinement and high-end, traditional hot air slitting and setting devices have gradually exposed many problems that are difficult to meet the current production needs.

[0003] Traditional knitted fabric slitting and setting devices have many drawbacks in actual operation. During the slitting process, for knitted fabrics of different thicknesses or materials, it is difficult for ordinary devices to accurately adjust the holding force. If the holding force is improper, the knitted fabric is extremely likely to have wrinkles or uneven slitting, seriously affecting the appearance of the product and subsequent processing. Moreover, traditional knitted fabric slitting and setting devices cannot accurately adjust the tension according to the actual needs of the knitted fabric, resulting in problems such as relaxation or excessive stretching of the knitted fabric due to unstable tension during the processing, thereby affecting the dimensional stability and quality consistency of the product. At the same time, during the hot air setting stage of traditional knitted fabric slitting and setting devices, hot air is easily dissipated from the feed inlet and the discharge outlet, resulting in heat waste, which not only increases energy consumption but also reduces the setting effect. In addition, when the knitted fabric enters the protection box for setting, due to the lack of effective guidance and support, its surface is easily rubbed against the inlet and outlet of the protection box, causing wear of the knitted fabric and affecting the product quality. Summary of the Invention

[0004] The purpose of the present invention is to provide a hot air slitting and setting device, which solves the technical problems raised in the background art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A hot air slitting and setting device includes a workbench, a holding device, a slitting mechanism, a tension adjusting mechanism, and a hot air setting mechanism. The holding device includes two mounting seats. A first driving motor is arranged on the outer wall of one of the mounting seats. The output end of the first driving motor is fixedly provided with a driving roller. The outer wall of the end of the driving roller away from the first driving motor is rotationally connected to the inner wall of the other mounting seat. The outer walls of both mounting seats are penetrated with activity slots. Both sides of the inner wall of each activity slot are fixedly provided with sliding slots.

[0007] Preferably, the fabric-opening mechanism includes a second driving motor, a mounting frame, a base, and a shaft seat. The second driving motor is fixedly arranged on the outer wall of the mounting frame. The output end of the second driving motor is fixedly provided with a reciprocating lead screw. One end of the outer wall of the reciprocating lead screw away from the second driving motor is rotatably connected to the inner wall of the shaft seat. The shaft seat is fixedly installed on the top of the workbench. The mounting frame is fixedly installed on the top of the workbench. Two support rods are fixedly arranged between the mounting frame and the shaft seat, and the two support rods are respectively located on both sides of the reciprocating lead screw. The base is fixedly arranged on the top of the workbench. A placing roller is rotatably arranged on the top of the base. The reciprocating lead screw is rotatably connected to the inner wall of the base.

[0008] Preferably, the hot air setting mechanism includes a protective box. On the top of the protective box, a blower is arranged. On the top inner wall of the protective box, a blower box is arranged. The output end of the blower is communicated with the blower box. At the feeding port and the discharging port of the protective box, a pair of connecting blocks are fixedly arranged respectively. On the outer wall of each pair of connecting blocks, a block groove is formed. Inside each pair of block grooves, a support plate is slidably arranged. On the top inner wall of each pair of block grooves, a pressure spring is fixedly arranged. Each pressure spring is respectively connected to the corresponding support plate. Between each pair of support plates, a protective roller is rotatably arranged.

[0009] Preferably, each fixing screw is respectively located inside the corresponding compression spring. Each adjusting knob is respectively located above the corresponding movable block. Each adjusting cavity is respectively communicated with the inner wall of the corresponding adjusting knob. Each connecting rod is movably inserted into the inner wall of the corresponding adjusting knob.

[0010] Preferably, on the outer walls of both sides of each movable block, a limiting block is formed. The inner wall of each limiting block is slidably connected to the outer wall of the corresponding chute.

[0011] Preferably, the tension adjusting mechanism is slidably arranged above the workbench. A through hole and two seat holes are formed in the outer wall of the fixed seat. The inner wall of the through hole is threadedly connected to the outer wall of the reciprocating lead screw, and the outer wall of the seat hole is slidably connected to the inner wall of the seat hole.

[0013] Preferably, the hot air setting mechanism is fixedly arranged on the top of the workbench, and the tension adjusting mechanism is slidably arranged below the hot air setting mechanism.

[0014] Preferably, the edge spreading mechanism, the pressing device, the tension adjusting mechanism, and the hot air setting mechanism are arranged in sequence from left to right.

[0015] Compared with the related art, a hot air edge spreading and setting device provided by the present invention has the following beneficial effects:

[0016] 1. The present invention provides a hot air edge spreading and setting device. When using this hot air edge spreading and setting device, first place the knitted fabric to be processed on the placing roller at the edge spreading mechanism, and place the other end of the knitted fabric at the tension adjusting mechanism through the pressing device. As the knitted fabric unfolds, it enters the pressing device. Start the first driving motor, and the driving roller rotates accordingly, driving the driven roller to rotate together. The driven roller cooperates with the driving roller to clamp and convey the knitted fabric forward. During this process, if it is necessary to adjust the pressing force, it can be achieved by rotating the adjusting knob. The adjusting knob rotates threadedly on the fixed screw. Since the connecting rod is movably inserted into the inner wall of the adjusting knob, and the adjusting knob is located above the movable block, and the adjusting cavity is communicated with the inner wall of the adjusting knob, when the adjusting knob is rotated, the movable block will slide up and down along the sliding groove in the movable groove, thereby changing the distance between the driven roller and the driving roller and adjusting the magnitude of the pressing force on the knitted fabric to meet the processing requirements of knitted fabrics of different thicknesses or materials, so as to avoid wrinkles or uneven edge spreading of the knitted fabric.

[0017] 2. The present invention provides a hot air edge spreading and setting device. By starting the third driving motor, the bidirectional screw at its output end rotates, causing the two sliders threadedly connected to the bidirectional screw to move towards or away from each other. When the slider moves, it drives the double-shaft motor fixed thereon to move together. The double-shaft motor is started, and the adjusting plate at its output end rotates, thereby driving the clamping plate to rotate. By adjusting the rotation angle of the double-shaft motor, the clamping angle of the clamping plate can be changed. In cooperation with the movement of the slider, the tension of the knitted fabric can be accurately adjusted. At the same time, the anti-slip pads on the outer walls of the opposite sides of the clamping plate can increase the friction force with the knitted fabric, prevent the knitted fabric from slipping during the adjustment process, and ensure the accuracy of the tension adjustment.

[0018] 3. The present invention provides a hot air open-width setting device. By starting the second drive motor, the output end thereof drives the reciprocating lead screw to rotate. Since the through hole of the fixed seat is threadedly connected to the reciprocating lead screw, and the seat hole is slidably connected to the corresponding rod, when the reciprocating lead screw rotates, the tension adjusting mechanism will perform a reciprocating linear motion above the workbench. The reciprocating motion enables the knitted fabric to be evenly pulled during the open-width process, so that it gradually unfolds, avoiding wrinkles or uneven open-width;

[0019] 4. The present invention provides a hot air open-width setting device. After the knitted fabric adjusted in tension enters the hot air setting mechanism, the fan is turned on. The fan inhales the outside air and conveys it to the fan box. The processed hot air blows out from the fan box to perform setting treatment on the knitted fabric entering the protection box. The pressure spring gives the support plate a downward pressure, making the protection roller in close contact with the knitted fabric, playing a role in guiding and supporting the knitted fabric, effectively avoiding the phenomenon that the surface of the knitted fabric contacts the inlet and outlet of the protection box during the forward movement of the tension adjusting mechanism, resulting in wear of the knitted fabric. At the same time, to a certain extent, it prevents the hot air from dissipating from the feed port and the discharge port, improving the hot air setting effect and energy utilization rate.

The webbing spreading mechanism 3 includes a second driving motor 301, a mounting frame 302, a base 303, and a shaft seat 307. The second driving motor 301 is fixedly arranged on the outer wall of the mounting frame 302. The output end of the second driving motor 301 is fixedly provided with a reciprocating lead screw 305. One end of the reciprocating lead screw 305 away from the second driving motor 301 is rotatably connected to the inner wall of the shaft seat 307. The shaft seat 307 is fixedly installed on the top of the workbench 1. The mounting frame 302 is fixedly installed on the top of the workbench 1. Two support rods 306 are fixedly arranged between the mounting frame 302 and the shaft seat 307. The two support rods 306 are respectively located on both sides of the reciprocating lead screw 305. The base 303 is fixedly arranged on the top of the workbench 1. A placing roller 304 is rotatably arranged on the top of the base 303. The reciprocating lead screw 305 is rotatably connected to the inner wall of the base 303. The hot air shaping mechanism 5 includes a protective box 501. A blower 502 is arranged on the top of the protective box 501. A blower box 503 is arranged on the top inner wall of the protective box 501. The output end of the blower 502 is communicated with the blower box 503. A pair of connecting blocks 504 are fixedly arranged at the feeding port and the discharging port of the protective box 501. A block groove 505 is formed on the outer wall of each pair of connecting blocks 504. A support plate 507 is slidably arranged in the interior of each pair of block grooves 505. A pressure spring 506 is fixedly arranged on the top inner wall of each pair of block grooves 505. Each pressure spring 506 is respectively connected to the corresponding support plate 507. A protective roller 508 is rotatably arranged between each pair of support plates 507. The tension adjusting mechanism 4 is slidably arranged above the workbench 1. A through hole 402 and two seat holes 403 are formed on the outer wall of the fixed seat 401. The inner wall of the through hole 402 is threadedly connected to the outer wall of the reciprocating lead screw 305. The outer wall of the seat hole 403 is slidably connected to the inner wall of the seat hole 403. The pressing device 2 is fixedly arranged on the top of the workbench 1. The reciprocating lead screw 305 and the two support rods 306 are located below the pressing device 2.

[0037] In this embodiment, the third driving motor 405 is started, and the bidirectional screw 406 at its output end rotates, causing the two sliders 408 threadedly connected to the bidirectional screw 406 to move towards or away from each other. When the slider 408 moves, the dual-axis motor 409 fixed thereon is driven to move together. When the dual-axis motor 409 is started, the adjusting plate 410 at its output end rotates, and then drives the clamping plate 411 to rotate. By adjusting the rotation angle of the dual-axis motor 409, the clamping angle of the clamping plate 411 can be changed. In cooperation with the movement of the slider 408, the tension of the knitted fabric can be accurately adjusted. At the same time, the anti-slip pad 412 on the outer wall of the opposite side of the clamping plate 411 can increase the friction with the knitted fabric, prevent the knitted fabric from slipping during the adjustment process, and ensure the accuracy of the tension adjustment;

[0038] The second driving motor 301 is started, and the output end thereof drives the reciprocating screw rod 305 to rotate. Since the through hole 402 of the fixed seat 401 is threadedly connected to the reciprocating screw rod 305, and the seat hole 403 is slidably connected to the corresponding rod, when the reciprocating screw rod 305 rotates, the tension adjusting mechanism 4 will perform a reciprocating linear motion above the workbench 1. The reciprocating motion enables the knitted fabric to be evenly pulled during the opening process, so as to gradually unfold and avoid the occurrence of wrinkles or uneven opening;

[0039] The knitted fabric after tension adjustment enters the hot air shaping mechanism 5. The blower 502 is turned on. The blower 502 inhales the outside air and conveys it to the blower box 503. The processed hot air blows out from the blower box 503 to shape the knitted fabric entering the protection box 501. The pressure spring 506 gives a downward pressure to the support plate 507, so that the protection roller 508 is in close contact with the knitted fabric, playing a role in guiding and supporting the knitted fabric, effectively avoiding the phenomenon that the surface of the knitted fabric contacts the inlet and outlet of the protection box 501 during the forward movement of the tension adjusting mechanism 4, resulting in wear of the knitted fabric. At the same time, to a certain extent, it prevents the hot air from escaping from the feed port and the discharge port, improving the hot air shaping effect and energy utilization rate;

[0040] Through the coordinated work of the opening mechanism 3, the pressing device 2, the tension adjusting mechanism 4 and the hot air shaping mechanism 5, the whole device realizes the integrated processing of opening, pressing and conveying, tension adjustment and hot air shaping of the knitted fabric, effectively improving the processing efficiency and quality of the knitted fabric and meeting the production requirements of hot knitted fabric shaping.

[0041] Working principle: When using this hot air stenter equipment, first place the knitted fabric to be processed on the placing roller 304 at the spreading mechanism 3, and place the other end of the knitted fabric at the tension adjusting mechanism 4 through the pressing device 2. As the knitted fabric unfolds, it enters the pressing device 2. Start the first driving motor 202, and the driving roller 203 rotates accordingly, driving the driven roller 211 to rotate together. The driven roller 211 cooperates with the driving roller 203 to clamp and convey the knitted fabric forward. During this process, if it is necessary to adjust the pressing force, it can be achieved by rotating the adjusting knob 208. The adjusting knob 208 rotates threadedly on the fixed screw rod 205. Since the connecting rod 207 is movably inserted into the inner wall of the adjusting knob 208, and the adjusting knob 208 is located above the movable block 209, and the adjusting cavity 210 is communicated with the inner wall of the adjusting knob 208, when the adjusting knob 208 is rotated, the movable block 209 will slide up and down along the sliding groove 213 in the movable groove 204, thereby changing the distance between the driven roller 211 and the driving roller 203, and adjusting the magnitude of the pressing force on the knitted fabric to adapt to the processing requirements of knitted fabrics of different thicknesses or materials, so as to avoid wrinkles or uneven spreading of the knitted fabric;

[0042] Start the third driving motor 405, and the bidirectional screw rod 406 at its output end rotates, causing the two sliders 408 threadedly connected to the bidirectional screw rod 406 to move towards or away from each other. When the sliders 408 move, they drive the double-shaft motor 409 fixed thereon to move together. The double-shaft motor 409 is started, and the adjusting plate 410 at its output end rotates, thereby driving the clamping plate 411 to rotate. By adjusting the rotation angle of the double-shaft motor 409, the clamping angle of the clamping plate 411 can be changed. In cooperation with the movement of the sliders 408, the tension of the knitted fabric can be accurately adjusted. At the same time, the anti-slip pads 412 on the outer walls of the opposite sides of the clamping plate 411 can increase the friction with the knitted fabric, prevent the knitted fabric from slipping during the adjustment process, and ensure the accuracy of tension adjustment;

[0043] Start the second driving motor 301, and its output end drives the reciprocating screw rod 305 to rotate. Since the through hole 402 of the fixed seat 401 is threadedly connected to the reciprocating screw rod 305, and the seat hole 403 is slidably connected to the corresponding rod, when the reciprocating screw rod 305 rotates, the tension adjusting mechanism 4 will perform a reciprocating linear motion above the workbench 1. The reciprocating motion enables the knitted fabric to be evenly pulled during the spreading process, so as to gradually unfold and avoid wrinkles or uneven spreading;

[0044] The knitted fabric after tension adjustment enters the hot air shaping mechanism 5. The blower 502 is turned on. The blower 502 sucks in outside air and conveys it to the blower box 503. The processed hot air blows out from the blower box 503 to shape the knitted fabric entering the protective box 501. The pressure spring 506 applies a downward pressure on the support plate 507, making the protective roller 508 in close contact with the knitted fabric, which plays a role in guiding and supporting the knitted fabric, effectively avoiding the phenomenon that the surface of the knitted fabric contacts the inlet and outlet of the protective box 501 during the forward movement of the tension adjustment mechanism 4, thus preventing wear of the knitted fabric. At the same time, to a certain extent, it prevents the hot air from escaping from the feed inlet and the discharge outlet, improving the hot air shaping effect and energy utilization rate;

[0045] Through the coordinated work of the weft straightening mechanism 3, the pressing device 2, the tension adjustment mechanism 4 and the hot air shaping mechanism 5, the whole equipment realizes the integrated processing of weft straightening, pressing and conveying, tension adjustment and hot air shaping of the knitted fabric, effectively improving the processing efficiency and quality of the knitted fabric and meeting the production requirements of hot knitted fabric shaping.
