Description

Technical Field

[0001] This invention relates to the field of fabric printing and dyeing technology, specifically to a dye recovery type industrial textile printing and dyeing device. Background Technology

[0002] Industrial textile dyeing and printing equipment is a device specifically designed for dyeing textile fabrics. It is widely used in the textile industry. In the existing industrial textile dyeing process, the immersion dyeing method is usually adopted. The main processing steps of industrial textile dyeing and printing equipment are to immerse the textile fabric in the dye solution and use mechanical agitation to make the dye penetrate evenly into the fabric fibers. Finally, excess dye is removed, thereby achieving color fixation and uniform distribution.

[0003] However, in the actual process of textile production, if the textile is made of relatively loose fabrics such as cotton or felt, these fabrics are prone to carrying a large number of tiny air bubbles inside the fabric after entering the dye. When the surface of the fabric is wetted by the dye, it becomes even more difficult for the air bubbles inside the fabric to escape. These air bubbles not only hinder the effective penetration of the dye, but also cause incomplete dyeing inside the fabric, resulting in uneven dyeing and color difference or spots in the final product, affecting the appearance quality of the final product. Summary of the Invention

[0004] To address the problem of uneven dyeing caused by tiny air bubbles inside cotton and other textile fabrics after dyeing, this invention provides a dye-recovery industrial textile dyeing device.

[0010] As a preferred embodiment of the present invention, the rack, through the gear, the one-way wheel and the first roller, makes the distance of a single movement of the fabric less than half the length of the fabric corresponding to the movement range of the sliding block, so that the same position on the fabric is squeezed multiple times by the squeezing roller.

[0011] As a preferred embodiment of the present invention, the power assembly includes: an electric push rod fixedly connected to the printing and dyeing shell, the telescopic end of the electric push rod being fixedly connected to a connecting frame, the connecting frame being used to drive the two extrusion rollers to move synchronously; a fourth telescopic rod fixedly connected to the fixed frame, the telescopic end of the fourth telescopic rod being fixedly connected to an adjacent sliding block, the fourth telescopic rod being connected to a first liquid guide pipe, the first liquid guide pipe being connected to the third telescopic rod, and the fourth telescopic rod being filled with hydraulic oil.

[0013] As a preferred embodiment of the present invention, it further includes: a limiting mechanism disposed on one side of the sliding block, used to limit the maximum degree to which the extrusion roller extrudes the fabric according to the thickness of the fabric; the limiting mechanism includes: a sixth telescopic rod fixedly connected to one side of the sliding block, the sixth telescopic rod being connected to a second liquid guide pipe, the second liquid guide pipe being connected to the second telescopic rod, and the sixth telescopic rod being filled with hydraulic oil; two limiting bent rods slidably connected to the corresponding sliding blocks, the two limiting bent rods sliding relative to each other, and the limiting bent rods being fixedly connected to the telescopic end of the sixth telescopic rod; and two stops disposed on the corresponding ends of the extrusion rollers near the limiting bent rods, the sliding block being provided with two protrusions for limiting the rotation range of the extrusion roller, and the limiting bent rods cooperating with the stops to limit the maximum angle of rotation of the extrusion roller.

[0014] As a preferred embodiment of the present invention, the limiting mechanism further includes a guide plate disposed on one side of the printing and dyeing shell, the guide plate being used to flatten the fabric before it enters between the first roller and the second roller.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1.

[0017] 3. The present invention limits the rotation range of the stop block by limiting the limiting rod in the limiting mechanism, so that the maximum degree of extrusion that the extrusion roller can achieve on fabrics of different thicknesses can be adapted to change, thus ensuring the safety of the fabric dyeing process.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 12 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the 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.

[0032] Example 1: When existing dyeing equipment is used to dye industrial textiles, if the industrial textiles are relatively loose fabrics such as felt or cotton, a large number of tiny air bubbles will exist inside the fabric after the fabric enters the dye, which will prevent the dye from completely penetrating the fabric, resulting in color difference or spots in the final product and affecting the appearance quality of the final product.

[0033] A dye recovery type industrial textile dyeing and printing device, please refer to the attached document. Figure 1 - Appendix Figure 4 and attached Figure 6As shown, it includes: a printing and dyeing shell 1, a fixed frame 2 fixedly connected inside the printing and dyeing shell 1, and a sliding frame 3 slidably connected to the fixed frame 2; a fixed rod 4 fixedly connected to the sliding frame 3, two limiting blocks 5 slidably connected to one side of the fixed frame 2, and a sliding rod 6 slidably connected to the fixed frame 2, the limiting blocks 5 being used to support the sliding rod 6; two guide rollers 7 rotatably connected to the sides of the fixed frame 2 and the sliding frame 3 away from the fixed rod 4, respectively, and two sliding blocks 8 slidably connected to both the fixed frame 2 and the sliding frame 3, the two sliding blocks 8 on the fixed frame 2 being... A squeezing roller 9 is rotatably connected between the two sliding blocks 8 on the sliding frame 3. The squeezing roller 9 has a teardrop-shaped cross-section. A guiding mechanism is set on the printing and dyeing shell 1 to stably guide the fabric into the pigment on the printing and dyeing shell 1. Two conveying mechanisms are set on the printing and dyeing shell 1 for intermittently conveying the fabric. A limiting block 5 has an inclined surface on the side near the sliding rod 6. The inclined surface of the limiting block 5 is used to push the sliding rod 6 to move and reset. The width of the projection of the inclined surface of the limiting block 5 on the horizontal plane is smaller than the width of the sliding rod 6. The mechanism includes: two first rollers 201, both rotatably connected to a printing and dyeing shell 1; four support blocks 202 slidably connected to the printing and dyeing shell 1; a second roller 203 rotatably connected between two support blocks 202 near the same first roller 201; adjusting bolts provided on the printing and dyeing shell 1 for changing the distance between the first roller 201 and the adjacent second roller 203; and two adjusting components, both provided on the printing and dyeing shell 1, for adjusting the distance between the first roller 201 and the adjacent second roller 203 according to the... The distance between the fixed frame 2 and the sliding frame 3 is changed step by step. The adjustment component includes: a first telescopic rod 301, which is fixed to the printing and dyeing shell 1. The telescopic end of the first telescopic rod 301 is fixed to the adjacent support block 202. The first telescopic rod 301 is connected to the guide pipe 302; a second telescopic rod 303, which is fixed to the fixed frame 2. The telescopic end of the second telescopic rod 303 is fixed to the sliding frame 3. The second telescopic rod 303 is connected to the guide pipe 302. Both the first telescopic rod 301 and the second telescopic rod 303 are filled with hydraulic oil.

[0034] The above solution aims to address the problem of numerous micro-air bubbles in the fabric entering the dye bath, preventing the dye bath from fully penetrating the fabric and resulting in uneven dyeing. A control panel is installed on the dyeing shell 1, and a dye circulation mechanism is located at the rear of the dyeing shell 1. The inlet of the dye circulation mechanism is connected to the upper part of the dyeing shell 1, and the outlet is connected to the lower part of the dyeing shell 1, ensuring continuous circulation of the dye within the dyeing shell 1 and facilitating the recovery of the dye. Both the dye circulation mechanism and the conveying mechanism are electrically connected to the control panel. Two pressure rollers 9 are arranged in a vertically mirrored manner, and four sliding blocks 8 are located in front of the two pressure rollers 9. Initially, the teardrop-shaped tips of the two extrusion rollers 9 are biased towards the fabric. During the rotation of the extrusion rollers 9, the maximum distance between the two extrusion rollers 9 is less than the thickness of the fabric. This is used to make the extrusion rollers 9 rotate due to friction with the fabric when they move, thereby squeezing the fabric and squeezing out air bubbles. After the extrusion rollers 9 release the pressure on the fabric, the fabric relaxes and absorbs the dye. The dye quickly penetrates into the fabric. The fixed rod 4 and the sliding rod 6 are distributed in a mirror image, and the distance between the fixed rod 4 and the sliding rod 6 is less than the thickness of the fabric. The fixed rod 4 and the sliding rod 6 are used to squeeze and fix the fabric, so that the fabric is stationary relative to the fixed frame 2 when it is squeezed by the extrusion rollers 9.

[0035] Two guide rollers 7 are used to work with the fixed rod 4 and the sliding rod 6 to flatten the fabric. The fixed rod 4 and the sliding rod 6 are both located on the right side of the fixed frame 2 and the sliding frame 3, and the two guide rollers 7 are both located on the left side. The two extrusion rollers 9 are both located in the middle. The fabric is conveyed from right to left. The second circular roller 203 is located directly above the adjacent first circular roller 201. The distance between the first circular roller 201 and the second circular roller 203 on the left side is smaller than the distance between the first circular roller 201 and the second circular roller 203 on the right side. The first circular roller 201 and the second circular roller 203 on the left side provide the main power for conveying the fabric. Through the continuous reciprocating extrusion of the fabric by the two extrusion rollers 9, combined with the intermittent movement of the fabric, the tiny air bubbles in the fabric are effectively removed, which facilitates the rapid penetration of dye into the fabric and improves the uniformity of dyeing.

[0036] Workflow: When using this device to dye industrial textiles such as cotton or felt, the fabric is initially passed sequentially between the first and second rollers 201 and 203 on the right, between the fixed rod 4 and the sliding rod 6, between the two squeezing rollers 9, between the two guide rollers 7, and between the first and second rollers 201 and 203 on the left. Then, dye liquor is injected into the dyeing shell 1 through the dye circulation mechanism, maintaining continuous circulation. Simultaneously, the operator rotates the adjusting bolts to move the four support blocks 202 downwards, reducing the distance between the first roller 201 and the adjacent second roller 203. The right support block 202 causes the corresponding telescopic end of the first telescopic rod 301 to retract. Hydraulic oil in the first telescopic rod 301 enters the second telescopic rod 303 through the guide pipe 302. The telescopic end of the second telescopic rod 303 extends, bringing the fixed frame 2 and the sliding frame 3 closer together. When the fixed rod 4 and the sliding rod 6 compress and fix the fabric, the fabric cannot move. Rotating the adjusting bolts stops, completing the initial setup of the device. The operator then starts the conveying mechanism via the control panel.

[0037] When the conveying mechanism starts, it controls the two extrusion rollers 9 to move back and forth. The sliding block 8 moves synchronously with the extrusion rollers 9. When the extrusion rollers 9 move to the left, they rotate due to friction with the fabric. During the rotation, the degree of extrusion on the fabric gradually increases. When the friction between the extrusion rollers 9 and the fabric is insufficient to support the continued rotation of the extrusion rollers 9, they stop rotating. The two extrusion rollers 9 clamp the fabric and slide relative to each other. During the movement, the extrusion rollers 9 extrude pressure on the fabric to remove air bubbles. When the extrusion rollers 9 move to their left limit, the conveying mechanism moves the limit block 5 to the left and the sliding rod 6 moves downward. The fixed rod 4 and the sliding rod 6... Release the clamping and fixing of the fabric, and then the two squeezing rollers 9 move to the right to reset. The squeezing rollers 9 lose their squeezing of the fabric, and the conveying mechanism conveys the fabric to the left through the first circular roller 201 and the second circular roller 203 on the left. The fabric between the fixed frame 2 and the sliding frame 3 moves to the left a certain distance. When the squeezing rollers 9 move to the left limit position, the conveying mechanism resets the sliding rod 6, and the fixed rod 4 and the sliding rod 6 clamp and fix the fabric again. Repeat the above operation to make the fabric conveyed intermittently, and complete the dyeing operation of the fabric. The control panel shuts down the conveying mechanism, and finally the adjusting bolt is turned to the initial position. The dye is recovered through the dye circulation mechanism. At this point, all parts are returned to their initial positions.

[0038] Please refer to the appendix. Figure 1 Appendix Figure 3 - Appendix Figure 5 Appendix Figure 7 - Appendix Figure 10As shown, the conveying mechanism includes: a third telescopic rod 401, fixedly connected to the printing and dyeing shell 1, with a rack 402 fixedly connected to the telescopic end of the third telescopic rod 401, and hydraulic oil injected into the third telescopic rod 401; a one-way wheel 403, disposed on the first circular roller 201 away from the first telescopic rod 301, with gear transmission between the rack 402 and the one-way wheel 403; a power assembly, disposed on one side of the printing and dyeing shell 1, used to control the reciprocating movement of the extrusion roller 9 in coordination with the fabric conveying; and a locking assembly, disposed on the printing and dyeing shell 1. Inside, the rack 402 is used to release the fabric during fabric conveying. Through gears, a one-way wheel 403, and the first circular roller 201, the rack 402 ensures that the fabric moves a distance less than half the length of the fabric corresponding to the sliding block 8's movement range. This allows the same position on the fabric to be repeatedly squeezed by the squeezing roller 9. The power assembly includes: an electric push rod 501, fixed to the printing and dyeing shell 1; a connecting frame 502 fixed to the telescopic end of the electric push rod 501; and a fourth telescopic rod 50... 3. Fixed to the fixed frame 2, the telescopic end of the fourth telescopic rod 503 is fixed to the adjacent sliding block 8. The fourth telescopic rod 503 is connected to the first liquid guide pipe 504, which is connected to the third telescopic rod 401. Hydraulic oil is injected into the fourth telescopic rod 503. The locking assembly includes: a fifth telescopic rod 601, fixed to the dyeing shell 1, the fifth telescopic rod 601 is connected to the connecting pipe 602, which is connected to the fourth telescopic rod 503. Hydraulic oil is injected into the fifth telescopic rod 601; trigger block 6. 03, slidably connected to the fixed frame 2, the telescopic end of the fifth telescopic rod 601 is used to push the trigger block 603, the upper side of the trigger block 603 is provided with an inclined surface, the lower side of the limiting block 5 is provided with a groove, and the inclined surface of the trigger block 603 is used to squeeze the edge of the groove of the limiting block 5; the reset rod 604, slidably connected to the fixed frame 2, a spring is fixed between the reset rod 604 and the telescopic end of the fifth telescopic rod 601, the upper part of the reset rod 604 is provided with an inclined surface, and the inclined surface of the reset rod 604 is used to push the limiting block 5 to reset.

[0039] In the above scheme, the aim is to control the reciprocating movement of the extrusion roller 9 to coordinate with the intermittent movement of the fabric, so that the fabric is conveyed to the left only when the extrusion roller 9 moves and resets; the electric push rod 501 is electrically connected to the control panel, and the one-way wheel 403 only drives the left first circular roller 201 to rotate counterclockwise (viewed from front to back), so that the left first circular roller 201 and the second circular roller 203 convey the fabric to the left; the fourth telescopic rod 503 (in this device, the telescopic rods are composed of a cylinder, a piston, and a support rod, and the support rod in the telescopic rod is the telescopic end described in this device. The support rod controls the flow of hydraulic oil in the cylinder through the piston, and the piston divides the cylinder into two chambers) is an existing mechanism, and the connecting pipe 602 is connected to the fourth telescopic rod. The left chamber of 503 is connected, and the first liquid guide tube 504 is connected to the right chamber of the fourth telescopic rod 503. The shape of the limiting block 5 and the cross-sectional shape of its inner groove are both right trapezoidal. The inclined surface of the trigger block 603 is inclined from top to bottom to the left, the inclined surface of the limiting block 5 is inclined from top to bottom to the right, and the inclined surface of the reset rod 604 is inclined from top to bottom to the left. A part of the trigger block 603 is always located in the groove of the limiting block 5. Initially, the sliding rod 6 does not contact the inclined surface of the limiting block 5. The sliding rod 6 is relatively fixed to the fixed frame 2. The sliding rod 6 is controlled to move up and down by the limiting block 5, so that the sliding rod 6 and the fixed rod 4 work together to intermittently fix the fabric, so that the extrusion roller 9 extrudes the fabric and then quickly conveys the fabric.

[0040] Workflow: After the initial fabric arrangement is completed, the control panel activates the electric push rod 501. The telescopic end of the electric push rod 501 extends, and through the connecting frame 502, it drives the sliding block 8 and the squeezing roller 9 to move to the left. The squeezing roller 9 repeats the above-mentioned fabric squeezing operation. At this time, the fabric is clamped and cannot move. The movement of the sliding block 8 causes the telescopic end of the fourth telescopic rod 503 to retract. The hydraulic oil in the fourth telescopic rod 503 enters the fifth telescopic rod 601 through the connecting pipe 602. The telescopic end of the fifth telescopic rod 601 extends, and the third telescopic rod 401... The internal hydraulic oil flows into the fourth telescopic rod 503 through the first guide pipe 504. The telescopic end of the third telescopic rod 401 extends out and rotates the one-way wheel 403 through the rack 402 and gear. The first circular roller 201 on the left does not rotate. When the squeezing roller 9 moves to the left limit, the telescopic end of the fifth telescopic rod 601 contacts and pushes the trigger block 603 to move upward. The inclined surface of the trigger block 603 squeezes the edge of the groove of the limiting block 5. The limiting block 5 moves to the left. The inclined surface of the limiting block 5 contacts the sliding rod 6. The sliding rod 6 moves downward. The fixing rod 4 and the sliding rod 6 release the clamping of the fabric.

[0041] When the extrusion roller 9 moves to its left limit, the control panel controls the retraction end of the electric push rod 501 to retract, causing the extrusion roller 9 to move to the right. The retraction end of the fourth telescopic rod 503 extends, and the hydraulic oil in the first guide pipe 504 and connecting pipe 602 flows in opposite directions. The retraction end of the fifth telescopic rod 601 retracts, and the retraction end of the third telescopic rod 401 drives the rack 402 to move to the right. The rack 402, through the gear and one-way wheel 403, causes the first circular roller 201 on the left to rotate counterclockwise (viewed from front to back), and the fabric begins to be conveyed to the right, causing the fabric to be... When the squeezing position of the squeezing roller 9 changes, and the squeezing roller 9 moves to the right to reset, the telescopic end of the fifth telescopic rod 601 causes the inclined surface of the reset rod 604 to squeeze the limiting block 5 through the spring. The limiting block 5 moves to the right, and the inclined surface of the limiting block 5 pushes the sliding rod 6 to move upward. The fixing rod 4 and the sliding rod 6 resume clamping and fixing the fabric. The inclined surface of the limiting block 5 loses contact with the sliding rod 6 and returns to the initial state. The above operation is repeated until the dyeing operation of all the fabric is completed. Finally, the operator turns off the electric push rod 501 through the control panel.

[0042] Example 2: Based on Example 1, please refer to the appendix. Figure 1 Appendix Figure 2 Appendix Figure 6 Appendix Figure 8 Appendix Figure 11 and attached Figure 12 As shown, it also includes: a limiting mechanism, disposed on a sliding block 8 on one side, used to limit the maximum degree to which the extrusion roller 9 extrudes the fabric according to the thickness of the fabric. The limiting mechanism includes: a sixth telescopic rod 701, fixedly connected to a sliding block 8 on one side, the sixth telescopic rod 701 being connected to a second liquid guide pipe 702, the second liquid guide pipe 702 being connected to a second telescopic rod 303, and the sixth telescopic rod 701 being filled with hydraulic oil; two limiting bent rods 703, respectively slidably connected to corresponding sliding blocks 8, the two limiting bent rods 703 sliding relative to each other, limiting... The limiting bending rod 703 is fixedly connected to the telescopic end of the sixth telescopic rod 701; two stops 704 are respectively set at the end of the corresponding extrusion roller 9 near the limiting bending rod 703; two protrusions are provided on the sliding block 8 to limit the rotation range of the extrusion roller 9; the limiting bending rod 703 and the stops 704 cooperate to limit the maximum angle of rotation of the extrusion roller 9; the limiting mechanism also includes: a guide plate 705, which is set on one side of the printing and dyeing shell 1; the guide plate 705 is used to flatten the fabric before it enters between the first circular roller 201 and the second circular roller 203.

[0043] In the above solution, the aim is to address the problem that during the movement of the extrusion roller 9, the fabric is compressed. Because the fixed rod 4 and sliding rod 6 fix the fabric, a certain lateral tensile force is generated. If the rotation angle of the extrusion roller 9 is too large (i.e., the extrusion roller 9 compresses the fabric with excessive force), the excessive force of the extrusion roller 9 in compressing and stretching the fabric will cause the fabric to break or deform. The second liquid guide pipe 702 is connected to the lower chamber of the second telescopic rod 303, and the guide pipe 302 is connected to the upper chamber of the second telescopic rod 303. Initially, the upper extrusion roller 9 can only rotate counterclockwise (viewed from front to back) under the limitation of the protrusion on the adjacent sliding block 8. The upper and lower extrusion rollers 9 rotate in opposite directions. By changing the distance between the fixed frame 2 and the sliding frame 3, the position of the limiting bent rod 703 is changed, thereby limiting the maximum rotation angle of the extrusion rollers 9 and limiting the minimum distance between the two extrusion rollers 9. This allows the device to adjust the minimum distance between the two extrusion rollers 9 according to the thickness of the fabric, so that the tension on the fabric when the extrusion rollers 9 extrude the fabric can be controlled, ensuring the safety of the fabric. The upper side of the guide plate 705 is convex, which is used to spread the surface of the fabric and prevent the fabric entering between the first circular roller 201 and the second circular roller 203 from having wrinkles, which would lead to incomplete dyeing of the fabric.

[0044] Workflow: When the operator rotates the adjusting bolt, hydraulic oil in the first telescopic rod 301 enters the second telescopic rod 303, and the telescopic end of the second telescopic rod 303 extends. Some of the hydraulic oil in the second telescopic rod 303 enters the sixth telescopic rod 701 through the second guide pipe 702. The telescopic end of the sixth telescopic rod 701 extends and drives the two limit bends 703 to move to the right. The angle range of the subsequent stop 704 as the extrusion roller 9 rotates decreases. Then, the above dyeing and conveying operations of the fabric are repeated. The maximum extrusion degree of the extrusion roller 9 on the fabric is limited. During the fabric conveying process, the fabric first passes through the convex surface on the upper side of the guide plate 705, and the surface of the fabric is fully opened. Then, it enters between the first circular roller 201 and the second circular roller 203 on the right side. When the fabric is completely dyed, when the adjusting bolt is rotated to reset it, the hydraulic oil in the second guide pipe 702 flows in the reverse direction. The telescopic end of the sixth telescopic rod 701 retracts and drives the two limit bends 703 to move and reset. At this point, all parts have returned to their initial positions.
