Description

Technical Field

[0001] This invention relates to the field of mercerizing machine technology, specifically a mercerizing machine with dual-layer operation. Background Technology

[0002] Mercerizing machines are used to treat cotton yarns and fabrics with concentrated caustic soda solution under certain tension conditions and then wash them with water to remove alkali. In knitting production, they are mainly used to process weft-knitted tubular cotton greige fabrics. Mercerizing machines mainly consist of a fabric feeding frame, alkali soaking tank, ventilation device, width expansion device, rinsing device, and flat washing tank.

[0003] According to the authorization announcement number CN 105200689 B, a double-layer mercerizing machine includes a fabric feeding device, an alkali immersion padding device, a stretching device, an alkali removal device, and a fabric dropping device connected in sequence. The fabric feeding device is a double-layer fabric feeding frame. The alkali immersion padding device includes an alkali solution immersion tank, a high-efficiency padding car, a straight roller box, a two-roll padding car, an alkali removal mechanism, and a stretching roller connected in sequence. The stretching device includes a fabric stretching machine with clips arranged side by side and a stretching straight roller frame of the same length as the fabric stretching machine. The fabric dropping device is a double-layer fabric dropping frame. A distribution front padding car and distribution wheels are arranged between the alkali immersion padding device and the stretching device. This invention realizes a double-layer fabric feeding method for mercerizing machines. It can significantly increase the production capacity compared to existing single-layer fabric clip mercerizing machines while meeting the mercerizing requirements of imitation wax printing products, while reducing energy consumption and the failure rate. This greatly improves the production efficiency of the mercerizing machine and the quality of the subsequent imitation wax products. After using the above-mentioned existing double-layer mercerizing machine, it was found that:

[0004] The existing double-layer mercerizing machine does not have a measure to stretch the fabric, and the fabric is prone to deviation during transportation. Therefore, manual intervention and correction are required, which brings inconvenience to use. In addition, when the mercerizing machine is soaked in alkali, it only wets the fabric and the alkali is not thorough enough, so the fabric's weave gaps are not easily wetted. Summary of the Invention

[0005] To address these issues, the present invention provides a double-layer mercerizing machine.

[0006] This invention provides the following technical solution: a double-layer operating mercerizing machine, comprising:

[0007] The alkali immersion tank, the intermediate alkali tank, and the cleaning tank are located between the alkali immersion tank and the cleaning tank.

[0008] A fabric stretching mechanism is provided on the top of the alkali soaking tank. The fabric stretching mechanism is used for correcting the deviation of the fabric and loosening it.

[0009] The alkali impregnation mechanism is located inside the alkali impregnation tank and is used for alkali impregnation and strengthening of the fabric.

[0014] As a preferred embodiment of the present invention, the fabric stretching mechanism further includes a torsion rod, which passes through the front and back of the alkali soaking tank and is rotatably connected to the through hole of the alkali soaking tank. Two arc-shaped gears distributed front and back are fixedly connected to the outer wall of the torsion rod. The top of each of the two arc-shaped gears is engaged with a tooth block, and the top of the tooth block is fixedly connected to the bottom of the two guide seats respectively.

[0015] In a preferred embodiment of the present invention, a limiting seat is fixedly connected to the right end of the opposite face of each of the two guide seats, and a straightening rod is fixedly connected to the left side of each of the two limiting seats. A reset block is slidably connected to the outer wall of the straightening rod, and the reset block is fixedly connected to one side of the outer periphery of the slider. A second spring is sleeved around the outer periphery of each straightening rod. The second spring is located between the limiting seat and the reset block, and both ends of the second spring are fixedly connected to the side of the limiting seat and the reset block, respectively. A support block is fixedly connected to the bottom of each of the two guide seats, and multiple support columns are fixedly connected to the opposite face of each of the two support blocks. The end of the multiple support columns away from the support block is fixedly connected to the outer wall of the alkali leaching tank.

[0016] As a preferred embodiment of the present invention, a first guide hole is provided through the bottom of the first lifting block, and a second guide hole is provided through the top of the second lifting block. The second guide hole is located at the top of the first guide hole. Guide rods are movably connected to the inner walls of the first guide hole and the second guide hole. There are two guide rods, which are distributed front and back, and the bottoms of the two guide rods are fixedly connected to the bottom wall of the alkali leaching tank.

[0017] As a preferred embodiment of the present invention, each of the two turntables is fixedly connected to a drive rod at the center of its back side. The two drive rods respectively movably penetrate the front and back sides of the alkali leaching tank and are rotatably connected to the through hole of the alkali leaching tank.

[0018] In a preferred embodiment of the present invention, a cloth-winding roller is rotatably connected inside the alkali-soaking tank. A first driven pulley is fixedly connected to one end of the cloth-winding roller. A first power belt is sleeved on the outside of the first driven pulley. A first driving pulley is connected to the end of the first power belt away from the first driven pulley. The first driving pulley is fixedly connected to one end of the torsion rod. A second driving pulley is fixedly connected to the outer wall of the cloth-winding roller. The second driving pulley is located on one side of the first driven pulley. A second power belt is sleeved on the outside of the second driving pulley. A second driven pulley is connected to the end of the second power belt away from the second driving pulley. The second driven pulley is fixedly connected to one end of the drive rod.

[0019] As a preferred embodiment of the present invention, the alkali soaking tank is filled with a strong alkaline solvent, the medium alkali tank is filled with a medium alkali solvent, and the cleaning tank is filled with a cleaning agent.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. In this invention, two arc-shaped gears fixedly connected by a torsion bar rotate synchronously, further driving the toothed blocks meshing with the two arc-shaped gears to move to the right, thereby driving the two sliders and guide sliders to move synchronously to the right, thus driving the fabric strips and multiple clamps to move backward. During this process, the output terminals of multiple electromagnetic relays drive the vertically distributed clamps to move towards the center, so that the two vertically distributed clamps clamp the edge of the fabric. As the fabric strips move to the right, the cam pin slides along the straight groove, thereby pulling the two fabric strips forward and backward, causing the two fabric strips to move forward and backward along the two sliders, thereby driving the multiple clamps to move together, thus pulling the fabric, making the weave of the fabric looser. At the same time, the pulling of the fabric by the multiple clamps ensures that the fabric is always in the center of the alkali soaking tank, thereby avoiding the problem of fabric deviation.

[0022] 2. In this invention, the rotation of the fabric roller drives the second active pulley to rotate, which in turn drives the drive rod to rotate under the power transmission of the second power belt and the second passive pulley. This further causes the turntable to rotate. As the turntable rotates, it synchronously drives the second cam groove to rotate, causing the first and second positioning pins, which are slidably connected to the second cam groove, to swing up and down. This further drives the first and second lifting blocks to swing up and down, resulting in the injection plate, the scooping frame, and the upper pressure plate swinging up and down. When the injection plate swings upward, it drives the scooping frame to swing upward, scooping up the strong alkaline solvent inside the alkali soaking tank and conveying it upward until the top of the scooping frame abuts against the bottom of the fabric. At this time, the upper pressure plate just abuts against the top of the fabric. The injection plate is lifted upward by the first lifting block, pushing the strong alkaline solvent inside the scooping frame upward. Under the pressure of the injection plate, the strong alkaline solvent is better injected into the weave holes of the fabric, thereby improving the mercerizing effect of the fabric.

Detailed Implementation

[0032] 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.

[0033] Example: Please refer to Figure 1-8 The illustrated mercerizing machine comprises an alkali-impregnation tank 1, a medium alkali-impregnation tank 2, and a cleaning tank 3. The medium alkali-impregnation tank 2 is located between the alkali-impregnation tank 1 and the cleaning tank 3. The top of the alkali-impregnation tank 1 is equipped with a fabric stretching mechanism 4, which is used for correcting and loosening the fabric. The interior of the alkali-impregnation tank 1 is equipped with an alkali-impregnation mechanism 5, which is used for alkali-impregnating and strengthening the fabric. The interior of the alkali-impregnation tank 1 is filled with a strong alkaline solvent, the interior of the medium alkali-impregnation tank 2 is filled with a medium alkali solvent, and the interior of the cleaning tank 3 is filled with a cleaning agent.

[0034] In this embodiment, reference is made to Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the fabric stretching mechanism 4 includes two guide seats 401 distributed front to back. The two guide seats 401 are located at the top of the alkali soaking tank 1. Straight grooves 402 are provided at the top and bottom of the two guide seats 401. A first cam groove 403 is provided at the top of each of the two guide seats 401. The first cam groove 403 is located outside the straight groove 402. Two sliders 404 are slidably connected between the two straight grooves 402. Guide slide heads 405 are fixedly connected to the top of each of the two sliders 404. The interior of each of the two guide slide heads 405 is... A slidable, through-connected fabric strip 406 is provided. A cam pin 407 is fixedly connected to one bottom end of each fabric strip 406. The outer walls of the two cam pins 407 are slidably connected to the groove walls of the two first cam grooves 403, respectively. Two electromagnetic relays 408 are fixedly connected to the top and bottom of the ends of the two fabric strips 406 away from the two cam pins 407. The output ends of the two electromagnetic relays 408 at the top and the two electromagnetic relays 408 at the bottom are connected to a clamp 409. The two clamps 409 are symmetrically distributed vertically.

[0035] Specifically, the straight groove 402 provides precise sliding guidance for the slider 404, making its movement more stable. As the slider 404 moves to the right, the guide slide head 405 moves synchronously to the right, causing the fabric strip 406 and multiple clamps 409 to move backward. During this process, the outputs of multiple electromagnetic relays 408 drive the vertically distributed clamps 409 to move towards the center, clamping the fabric edges. As the fabric strip 406 moves to the right, the cam pin 407 slides along the straight groove 402, pulling the two fabric strips 406 forward and backward. This causes the two fabric strips 406 to move forward and backward along the two sliders 404, moving the multiple clamps 409 together. This stretches the fabric, loosening the weave. Simultaneously, the pulling of the fabric by the multiple clamps 409 ensures that the fabric remains centered in the alkali-soaking tank 1, preventing fabric deviation.

[0036] In this embodiment, reference is made to Figure 2 , Figure 7 , Figure 8As shown, the alkali leaching mechanism 5 includes four third springs 501 and an upper pressure plate 508. The four third springs 501 are all fixedly connected to the top wall of the alkali leaching tank 1. A scooping frame 502 is connected to the top of the four third springs 501. A material injection pressure plate 503 is slidably connected to the inner wall of the scooping frame 502. Four fourth springs 504 are fixedly connected to the bottom of the material injection pressure plate 503. The bottom of the fourth springs 504 is fixedly connected to the bottom wall of the scooping frame 502. Two sliding openings 505, distributed front and rear, are opened through the bottom wall of the scooping frame 502. First lifting blocks 506 are slidably connected inside the two sliding openings 505. The two first lifting blocks 506 have two upward-facing... A first positioning pin 507 is fixedly connected. An upper pressure plate 508 is located on top of an injection pressure plate 503. A second lifting block 509 is fixedly connected to the front and rear of the injection pressure plate 503. A second positioning pin 5010 is fixedly connected to the back of each of the two second lifting blocks 509. The second positioning pin 5010 has the same specifications and size as the first positioning pin 507. The plate also includes a turntable 5011. There are two turntables 5011. The two turntables 5011 are distributed in a front-to-back manner. A second cam groove 5012 is opened on the opposite surface of each of the two turntables 5011. The second cam groove 5012 slides around the first positioning pin 507 and the second positioning pin 5010.

[0037] Specifically, rotating the turntable 5011 causes the second cam groove 5012 to rotate, and the first positioning pin 507 and the second positioning pin 5010, which are slidably connected to the second cam groove 5012, swing up and down, further driving the first lifting block 506 and the second lifting block 509 to swing up and down. This causes the injection pressure plate 503, the scooping frame 502, and the upper pressure plate 508 to swing up and down. When the injection pressure plate 503 swings upward, it drives the scooping frame 502 to swing upward, scooping up the strong alkaline solvent inside the alkali soaking tank 1 and conveying it upward until the top of the scooping frame 502 abuts against the bottom of the fabric. At this time, the upper pressure plate 508 just abuts against the top of the fabric, and the injection pressure plate 503 moves upward under the support of the first lifting block 506, pushing the strong alkaline solvent inside the scooping frame 502 upward. Under the pressure of the injection pressure plate 503, the strong alkaline solvent is better injected into the weave holes of the fabric, thereby improving the mercerizing effect of the fabric.

[0038] In this embodiment, reference is made to Figure 5 , Figure 6 As shown, each electromagnetic relay 408 is fitted with a first spring 4010, which is fixedly connected between the fabric strip 406 and the clamp 409.

[0039] Specifically, the output terminals of multiple electromagnetic relays 408 drive the vertically distributed clamps 409 to move towards the center, so that the two vertically distributed clamps 409 clamp the edge of the fabric. During this process, the first spring 4010 is compressed and stores energy, so that when the multiple electromagnetic relays 408 are de-energized, the tension on the clamps 409 is lost. At this time, the clamps 409 are reset by the rebound force of the first spring 4010, releasing the clamping effect on the fabric, so as to facilitate the subsequent need to clamp the fabric again.

[0040] In this embodiment, reference is made to Figure 4 As shown, the fabric stretching mechanism 4 also includes a torsion bar 4011, which penetrates the front and back of the alkali soaking tank 1 and is rotatably connected to the through hole of the alkali soaking tank 1. Two arc-shaped gears 4012, distributed front and back, are fixedly connected to the outer wall of the torsion bar 4011. The tops of the two arc-shaped gears 4012 are meshed with tooth blocks 4013. The tops of the tooth blocks 4013 are fixedly connected to the bottoms of the two guide seats 401 respectively. Limit seats 4014 are fixedly connected to the right ends of the opposite surfaces of the two guide seats 401. Straightening rods 4015 are fixedly connected to the left sides of the two limit seats 4014. The outer wall of the straightening rods 4015 is slidably connected to... A reset block 4016 is attached, which is fixedly connected to one side of the outer periphery of the slider 404. A second spring 4017 is sleeved on the outer periphery of the straightening rod 4015. The second spring 4017 is located between the limiting seat 4014 and the reset block 4016. The two ends of the second spring 4017 are fixedly connected to the side of the limiting seat 4014 and the reset block 4016, respectively. A support block 4018 is fixedly connected to the bottom of each of the two guide seats 401. Multiple support columns 4019 are fixedly connected to the opposite surfaces of the two support blocks 4018. The end of the multiple support columns 4019 away from the support block 4018 is fixedly connected to the outer wall of the alkali soaking tank 1.

[0041] Specifically, by rotating the torsion bar 4011, the two arc-shaped gears 4012 fixedly connected to the torsion bar 4011 rotate synchronously, further driving the tooth block 4013 meshing with the two arc-shaped gears 4012 to move to the right, thereby driving the two sliders 404 and the guide slider 405 to move synchronously to the right, thus driving the fabric strip 406 and multiple clamps 409 to move backward. During this process, the output terminals of multiple electromagnetic relays 408 drive the vertically distributed clamps 409 to move towards the center, so that the two vertically distributed clamps 409 clamp the edge of the fabric. As the fabric strip 406 moves to the right, the cam pin 407 slides along the straight groove 402, thereby pulling the two fabric strips 406 forward and backward, causing the two fabric strips 406 to move forward and backward along the two sliders 404, thereby driving the multiple clamps 409 to move together, thus stretching the fabric and making the fabric... The weaving threads become looser, and the multiple clamps 409 pull the fabric back and forth, keeping it centered in the alkali soaking tank 1, thus preventing the fabric from shifting. When the slider 404 moves to the right, it drives the reset block 4016 to move synchronously, compressing the second spring 4017 and causing it to rebound. Because the arc gear 4012 has incomplete teeth, when the incomplete part of the arc gear 4012 rotates to the bottom of the tooth block 4013, the tooth block 4013 is not engaged by the arc gear 4012. At this time, the system shuts down multiple electromagnetic relays 408. Under the rebound force of the first spring 4010, the two clamps 409 are pushed to the sides, releasing the fabric. The rebound force of the second spring 4017 then drives the slider 404 to slide back to its original position, and the fabric is then pulled in a cyclical manner.

[0042] In this embodiment, reference is made to Figure 7 As shown, a first guide hole 5013 is provided through the bottom of the first lifting block 506, and a second guide hole 5014 is provided through the top of the second lifting block 509. The second guide hole 5014 is located at the top of the first guide hole 5013. A guide rod 5015 is movably connected to the inner walls of the first guide hole 5013 and the second guide hole 5014. There are two guide rods 5015, which are distributed front and back. The bottom of the two guide rods 5015 is fixedly connected to the bottom wall of the alkali soaking tank 1.

[0043] Specifically, the guide rod 5015 is slidably connected to the first guide hole 5013 and the second guide hole 5014, thereby providing a precise guiding effect for the upper pressure plate 508 and the injection pressure plate 503, ensuring the stability of the swing of the injection pressure plate 503 and the upper pressure plate 508, and thus further ensuring the alkali impregnation effect on the fabric.

[0044] In this embodiment, reference is made to Figure 3 , Figure 7As shown, drive rods 5016 are fixedly connected to the center of the back side of both turntables 5011. The two drive rods 5016 respectively movably pass through the front and back of the alkali soaking tank 1 and are rotatably connected to the through hole of the alkali soaking tank 1. A cloth winding roller 6 is rotatably connected inside the alkali soaking tank 1. A first passive pulley 9 is fixedly connected to one end of the cloth winding roller 6. A first power belt 8 is sleeved on the outside of the first passive pulley 9. A first drive pulley 7 is connected to the end of the first power belt 8 away from the first passive pulley 9. The first drive pulley 7 is fixedly connected to one end of the torsion rod 4011. A second drive pulley 10 is fixedly connected to the outer wall of the cloth winding roller 6. The second drive pulley 10 is located on one side of the first passive pulley 9. A second power belt 11 is sleeved on the outside of the second drive pulley 10. A second passive pulley 12 is connected to the end of the second power belt 11 away from the second drive pulley 10. The second passive pulley 12 is fixedly connected to one end of the drive rod 5016.

[0045] Specifically, when the fabric moves, it drives the rotating cloth roller 6 to rotate. The rotating cloth roller 6 drives the first passive pulley 9 to rotate, which in turn drives the torsion bar 4011 to rotate under the power transmission of the first power belt 8 and the first active pulley 7, thus realizing the overall operation of the cloth stretching mechanism 4. During the rotation of the cloth roller 6, it drives the second active pulley 10 to rotate, which in turn drives the drive rod 5016 to rotate under the power transmission of the second power belt 11 and the second passive pulley 12, further causing the turntable 5011 to rotate as well, thus realizing the overall operation of the alkali soaking mechanism 5.

[0046] This solution involves a double-layer mercerizing machine that, during operation, stacks two layers of fabric together to form a master roll. The fabric is then pulled by an external winding mechanism, allowing it to be released from the outer master roll. It then travels through multiple guide rollers within the alkali-soaking tank 1, the intermediate alkali tank 2, and the cleaning tank 3. As the fabric moves, it rotates around a fabric roller 6, which in turn rotates the first passive pulley 9. This rotation, in turn, drives the torsion bar 4011 to rotate under the power transmission of the first power belt 8 and the first active pulley 7. This ensures that the torsion bar 4011 is fixedly connected to the torsion bar 4011. The two arc-shaped gears 4012 rotate synchronously, further driving the toothed block 4013 meshing with the two arc-shaped gears 4012 to move to the right, thereby driving the two sliders 404 and the guide slider 405 to move synchronously to the right, thereby driving the fabric strip 406 and multiple clamps 409 to move backward. During this process, the output terminals of multiple electromagnetic relays 408 drive the vertically distributed clamps 409 to move towards the center, so that the two vertically distributed clamps 409 clamp the edge of the fabric. As the fabric strip 406 moves to the right, the cam pin 407 moves along the straight groove 4 02 Sliding, thereby pulling the two fabric strips 406 forward and backward, causing them to move along the two sliders 404, which in turn moves the multiple clamps 409, thus pulling the fabric and loosening the weave. Simultaneously, the pulling of the fabric by the multiple clamps 409 keeps it centered in the alkali-soaking tank 1, preventing fabric deviation. When the slider 404 moves to the right, it causes the reset block 4016 to move synchronously, compressing the second spring 4017, resulting in... The second spring 4017 generates a rebound force. Since the arc gear 4012 is designed with incomplete teeth, when the incomplete part of the arc gear 4012 rotates to the bottom of the tooth block 4013, the tooth block 4013 is not engaged by the arc gear 4012. At this time, the system shuts down multiple electromagnetic relays 408. Under the action of the rebound force of the first spring 4010, the two clamps 409 are pushed to both sides, thereby releasing the clamping of the fabric. At this time, the rebound force of the second spring 4017 drives the slider 404 to slide and reset. Then, the fabric is pulled in this cycle.

[0047] During the rotation of the fabric roller 6, the second drive pulley 10 will rotate, causing the drive rod 5016 to rotate under the power transmission of the second power belt 11 and the second driven pulley 12. This further causes the turntable 5011 to rotate as well. During the rotation of the turntable 5011, the second cam groove 5012 will rotate synchronously, causing the first positioning pin 507 and the second positioning pin 5010, which are slidably connected to the second cam groove 5012, to swing up and down. This further causes the first lifting block 506 and the second lifting block 509 to swing up and down, thereby causing the material injection plate 503 and the material scooping plate 503 to swing up and down. The frame 502 and the upper pressure plate 508 swing up and down. When the injection pressure plate 503 swings upward, it drives the scooping frame 502 to swing upward, scooping up the strong alkaline solvent inside the alkali soaking tank 1 and conveying it upward until the top of the scooping frame 502 abuts against the bottom of the fabric. At this time, the upper pressure plate 508 just abuts against the top of the fabric, while the injection pressure plate 503 is lifted upward by the first lifting block 506, pushing the strong alkaline solvent inside the scooping frame 502 upward. Under the pressure of the injection pressure plate 503, the strong alkaline solvent is better injected into the weave holes of the fabric, thereby improving the mercerizing effect of the fabric.
