Description

[0002] Industrial textile printing and dyeing equipment is a kind of equipment specially used for dyeing textile fabrics, which is widely used in textile industry. In the existing industrial textile fabric dyeing process, the immersion dyeing method is usually adopted. The main processing steps of the industrial textile fabric printing and dyeing equipment are to immerse the textile fabric in the dye solution and cooperate with mechanical stirring to make the dye evenly penetrate into the fabric fiber, and finally remove the excess dye to achieve color fixation and uniform distribution.

[0003] However, in the actual operation process of textile fabrics, if the textile fabrics are relatively bulky fabrics such as cotton fabrics and felt fabrics, after these fabrics enter the dye, a large number of tiny bubbles are easily entrained inside the fabrics. When the surface of the fabrics is soaked with the dye, it will make the bubbles in the fabrics more difficult to discharge.

[0021] Example 1: When the existing printing and dyeing device is dyeing industrial textile fabrics, if the industrial textile fabrics are relatively bulky fabrics such as felt or cotton, after the fabric enters the dye, a large number of tiny bubbles will exist inside the fabric, so that the dye solution cannot completely enter the fabric, resulting in color difference or spots in the final product, affecting the appearance quality of the final product.

The mechanism comprises: two first round rollers 201, both of which are rotatably connected to the printing and dyeing shell 1, four support blocks 202 are slidably connected to the printing and dyeing shell 1, a second round roller 203 is rotatably connected between two support blocks 202 close to the same first round roller 201, and an adjusting bolt is arranged on the printing and dyeing shell 1, and the adjusting bolt is used to change the distance between the first round roller 201 and the adjacent second round roller 203; two adjusting components are both arranged on the printing and dyeing shell 1, and are used to adjust the distance between the first round roller 201 and the adjacent second round roller 203 according to the same In order to change the spacing between the fixed frame 2 and the sliding frame 3, the adjustment component includes: a first telescopic rod 301, which is fixedly connected to the printing and dyeing shell 1, the telescopic end of the first telescopic rod 301 is fixedly connected to the adjacent support block 202, and the first telescopic rod 301 is connected to the guide tube 302; a second telescopic rod 303, which is fixedly connected to the fixed frame 2, the telescopic end of the second telescopic rod 303 is fixedly connected to the sliding frame 3, the second telescopic rod 303 is connected to the guide tube 302, and the first telescopic rod 301 and the second telescopic rod 303 are filled with hydraulic oil.

[0023] In the above scheme, the problem that a large number of tiny bubbles exist in the cloth entering the dye solution, resulting in the inability of the dye solution to completely enter the cloth, causing uneven dyeing of the cloth is solved; a control panel is provided on the printing and dyeing shell 1, and a dye circulation mechanism is provided at the rear of the printing and dyeing shell 1. The liquid inlet of the dye circulation mechanism is connected to the upper part of the printing and dyeing shell 1, and the liquid outlet of the dye circulation mechanism is connected to the lower part of the printing and dyeing shell 1, so as to keep the dye in the printing and dyeing shell 1 in a state of continuous circulation, and at the same time facilitate the recovery of the dye in the printing and dyeing shell 1. The dye circulation mechanism and the conveying mechanism are both electrically connected to the control panel, and the two squeezing rollers 9 are distributed in upper and lower mirror images, and the four sliding blocks 8 are respectively located in front of the two squeezing rollers 9. At the rear two ends, initially, the water drop-shaped tips of the two squeezing rollers 9 are biased toward the cloth. During the rotation of the squeezing rollers 9, the maximum distance between the two squeezing rollers 9 is less than the thickness of the cloth, so that when the squeezing rollers 9 move, the squeezing rollers 9 rub against the cloth and rotate to squeeze the cloth, so as to squeeze out the bubbles in the cloth. After the squeezing rollers 9 release the squeezing of the cloth, the cloth relaxes and absorbs the dye liquid, and the dye liquid quickly soaks into the cloth. The fixed rod 4 and the sliding rod 6 are distributed in upper and lower mirror images, and the distance between the fixed rod 4 and the sliding rod 6 is less than the thickness of the cloth. The fixed rod 4 and the sliding rod 6 are used to squeeze and fix the cloth, so that the cloth is stationary relative to the fixed frame 2 when the cloth is squeezed by the squeezing rollers 9.

[0024] The two guide rollers 7 are used to cooperate with the fixed rod 4 and the sliding rod 6 to flatten the cloth. 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, the two guide rollers 7 are both located on the left side, and the two squeezing rollers 9 are both located in the middle. The cloth is transported from right to left. The second round roller 203 is located directly above the adjacent first round roller 201. The spacing between the first round roller 201 and the second round roller 203 on the left side is smaller than the spacing between the first round roller 201 and the second round roller 203 on the right side. The first round roller 201 and the second round roller 203 on the left side provide the main power for conveying the cloth. The continuous reciprocating squeezing of the cloth by the two squeezing rollers 9 and the intermittent movement of the cloth can effectively remove the tiny bubbles in the cloth, which is convenient for the dye to quickly penetrate the cloth and improve the uniformity of cloth dyeing.

[0025] Workflow: When the device is used to dye industrial textile fabrics such as cotton or felt, the fabric is initially passed through the first round roller 201 and the second round roller 203 on the right side, 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 round roller 201 and the second round roller 203 on the left side in sequence, and then the dyeing liquid is injected into the printing and dyeing shell 1 through the dye circulation mechanism to keep the dyeing liquid in a state of continuous circulation. At the same time, the operator rotates the adjusting bolt to move the four support blocks 202 downward to reduce the distance between the first round roller 201 and the adjacent second round roller 203. The support block 202 on the right side shrinks the telescopic end of the corresponding first telescopic rod 301, and the hydraulic oil in the first telescopic rod 301 enters the second telescopic rod 303 through the guide tube 302. The telescopic end of the second telescopic rod 303 extends and brings the fixed frame 2 and the sliding frame 3 closer to each other. When the fixed rod 4 and the sliding rod 6 squeeze and fix the fabric, the fabric cannot move, and the adjusting bolt stops rotating. At this point, the initial arrangement of the device is completed, and the operator starts the conveying mechanism through the control panel.

[0026] When the conveying mechanism is started, the conveying mechanism controls the two squeezing rollers 9 to move back and forth left and right, and the sliding block 8 moves synchronously with the squeezing rollers 9. When the squeezing rollers 9 move to the left, the squeezing rollers 9 rotate due to friction with the cloth. The squeezing degree of the two squeezing rollers 9 on the cloth gradually increases during the rotation. When the friction between the squeezing rollers 9 and the cloth is not enough to support the squeezing rollers 9 to continue to rotate, the squeezing rollers 9 stop rotating, and the two squeezing rollers 9 clamp the cloth and slide relatively. The squeezing rollers 9 squeeze the cloth during the movement to remove bubbles in the cloth. When the squeezing rollers 9 move to the left to the limit, the conveying mechanism causes the limit block 5 to move to the left, the sliding rod 6 moves downward, and the fixed rod 4 and the sliding rod 6 The clamping and fixation of the cloth is released, and then the two squeezing rollers 9 move to the right and reset. The squeezing rollers 9 lose squeezing the cloth, and the conveying mechanism conveys the cloth to the left through the first round roller 201 and the second round roller 203 on the left. The cloth between the fixed frame 2 and the sliding frame 3 moves a distance to the left. When the squeezing roller 9 moves to the left to the limit position, the conveying mechanism resets the sliding rod 6, and the fixed rod 4 and the sliding rod 6 clamp and fix the cloth again. The above operations are repeated continuously to make the cloth intermittently conveyed, and the dyeing operation of the cloth is completed. The control panel closes the conveying mechanism, and finally the adjusting bolt is turned to the initial position, and the dye is recovered through the dye circulation mechanism. At this point, all parts are restored to their initial positions.

The power assembly includes: an electric push rod 501, which is fixed to the printing and dyeing shell 1, and the telescopic end of the electric push rod 501 is fixed to a connecting frame 502, and the connecting frame 502 is used to drive the two squeezing rollers 9 to move synchronously; 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 tube 504, the first liquid guide tube 504 is connected to the third telescopic rod 401, the fourth telescopic rod 503 is filled with hydraulic oil, the locking assembly includes: a fifth telescopic rod 601, fixed to the printing and dyeing shell 1, the fifth telescopic rod 601 is connected to the connecting tube 602, the connecting tube 602 is connected to the fourth telescopic rod 503, and the fifth telescopic rod 601 is filled with hydraulic oil; a trigger block 6 03, is 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, and the lower side of the limit 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 limit block 5; the reset rod 604, is slidably connected to the fixed frame 2, a spring is fixedly connected 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 limit block 5 to reset.

[0028] In the above scheme, the left and right reciprocating movement of the squeezing roller 9 is controlled to cooperate with the intermittent movement of the cloth, and the cloth is transported to the left only when the squeezing roller 9 moves to reset; the electric push rod 501 is electrically connected to the control panel, and the one-way wheel 403 only drives the first round roller 201 on the left to rotate counterclockwise (from front to back), so that the first round roller 201 and the second round roller 203 on the left transport the cloth to the left, and the fourth telescopic rod 503 (the telescopic rods in this device are composed of a cylinder, a piston and a support rod. 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, the first liquid guide tube 504 is connected with the right chamber of the fourth telescopic rod 503, the shape of the limit block 5 and the cross-sectional shape of the inner groove thereof are both right-angled trapezoids, the inclined surface of the trigger block 603 is inclined to the left from top to bottom, the inclined surface of the limit block 5 is inclined to the right from top to bottom, and the inclined surface of the reset rod 604 is inclined to the left from top to bottom, and a part of the trigger block 603 is always located in the groove of the limit block 5. Initially, the sliding rod 6 does not contact the inclined surface of the limit block 5, and 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 limit block 5, so that the sliding rod 6 and the fixed rod 4 cooperate to intermittently fix the cloth, so that the squeezing roller 9 squeezes the cloth and then quickly transports the cloth.

[0029] Workflow: After the initial arrangement of the fabric is completed, the control panel starts the electric push rod 501, the telescopic end of the electric push rod 501 extends, and the telescopic end of the electric push rod 501 drives the sliding block 8 and the squeezing roller 9 to move to the left through the connecting frame 502, and the squeezing roller 9 repeats the above-mentioned fabric squeezing operation. At this time, the fabric is clamped and cannot move, and the sliding block 8 moves to shrink the telescopic end of the fourth telescopic rod 503, and the hydraulic oil in the fourth telescopic rod 503 enters the fifth telescopic rod 601 through the connecting pipe 602, and 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 liquid 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 the gear, and the first round roller 201 on the left does not rotate. When the squeezing roller 9 moves to the left to the limit, the telescopic end of the fifth telescopic rod 601 contacts and pushes the trigger block 603 to move upward, and the inclined surface of the trigger block 603 squeezes the edge of the groove of the limit block 5, and the limit block 5 moves to the left. The inclined surface of the limit block 5 contacts the sliding rod 6, and the sliding rod 6 moves downward, and the fixed rod 4 and the sliding rod 6 release the clamping of the cloth.

[0030] When the squeezing roller 9 moves to the left to the limit, the control panel controls the telescopic end of the electric push rod 501 to retract, the squeezing roller 9 moves to the right, the telescopic end of the fourth telescopic rod 503 extends, the hydraulic oil in the first liquid guide tube 504 and the connecting tube 602 flows in the opposite direction, the telescopic end of the fifth telescopic rod 601 retracts, the telescopic end of the third telescopic rod 401 drives the rack 402 to move to the right, the rack 402 rotates the first round roller 201 on the left counterclockwise (from front to back) through the gear and the one-way wheel 403, and the cloth begins to be transported to the right, so that the cloth is The squeezing position of the squeezing roller 9 changes. When 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 limit block 5 through the spring, and the limit block 5 moves to the right. The inclined surface of the limit block 5 pushes the sliding rod 6 to move upward, and the fixed rod 4 and the sliding rod 6 resume clamping and fixing the cloth. The inclined surface of the limit 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 cloth is completed. Finally, the operator turns off the electric push rod 501 through the control panel.

[0031] Example 2: Based on Example 1, please refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 6 , Attachment Figure 8 , Attachment Fig.11 and attached Fig.12 As shown, it also includes: a limiting mechanism, which is arranged on the sliding block 8 on one side, and is used to limit the maximum degree of squeezing of the cloth by the squeezing roller 9 according to the thickness of the cloth. The limiting mechanism includes: a sixth telescopic rod 701, which is fixed to the sliding block 8 on one side, the sixth telescopic rod 701 is connected to the second liquid guide tube 702, the second liquid guide tube 702 is connected to the second telescopic rod 303, and the sixth telescopic rod 701 is filled with hydraulic oil; two limiting bent rods 703, which are respectively slidably connected to the corresponding sliding blocks 8, and the two limiting bent rods 703 slide against each other to limit The limiting bending rod 703 is fixedly connected to the telescopic end of the sixth telescopic rod 701; two blocks 704 are respectively arranged at one end of the corresponding squeezing roller 9 close to the limiting bending rod 703, and two protrusions are arranged on the sliding block 8 to limit the rotation range of the squeezing roller 9. The limiting bending rod 703 and the block 704 cooperate to limit the maximum rotation angle of the squeezing roller 9.

[0032] In the above scheme, the problem of squeezing the fabric during the movement of the squeezing roller 9 is solved. Since the fixed rod 4 and the sliding rod 6 fix the fabric, a certain lateral tensile force will be generated on the fabric. If the squeezing roller 9 rotates at an angle that is too large (i.e., the force of squeezing the fabric by the squeezing roller 9 is too large), the force of squeezing and stretching the fabric by the squeezing roller 9 will be too large, causing the fabric to break or deform. The second liquid guide tube 702 is connected to the lower chamber of the second telescopic rod 303, and the liquid guide tube 302 is connected to the upper chamber of the second telescopic rod 303. Initially, the upper squeezing roller 9 can only rotate counterclockwise (from front to back) under the limit of the protrusion on the adjacent sliding block 8. The upper and lower squeezing rollers 9 rotate in opposite directions, and the position of the limit bending rod 703 is changed by changing the spacing between the fixed frame 2 and the sliding frame 3, thereby achieving the purpose of limiting the maximum rotation angle of the squeezing roller 9 and limiting the minimum spacing between the two squeezing rollers 9, so that the device can adaptably adjust the minimum spacing between the two squeezing rollers 9 according to the thickness of the cloth, so that the tension on the cloth when the squeezing rollers 9 squeeze the cloth is controlled to ensure the safety of the cloth. The upper side surface of the guide plate 705 is in a convex state, which is used to open the surface of the cloth to prevent the cloth entering between the first round roller 201 and the second round roller 203 from wrinkling, resulting in incomplete dyeing range of the cloth.

[0033] Working process: when the operator turns the adjusting bolt, the hydraulic oil in the first telescopic rod 301 enters the second telescopic rod 303, the telescopic end of the second telescopic rod 303 extends, and part of the hydraulic oil in the second telescopic rod 303 enters the sixth telescopic rod 701 through the second liquid guide tube 702, the telescopic end of the sixth telescopic rod 701 extends and drives the two limit bent rods 703 to move to the right, and the subsequent stopper 704 is reduced with the rotation angle range of the squeezing roller 9, and then the above-mentioned cloth dyeing and conveying operations are repeated, and the maximum squeezing degree of the cloth by the squeezing roller 9 is limited. During the cloth conveying process, the cloth first passes through the convex surface on the upper side of the guide plate 705, and the surface of the cloth is fully opened, and then enters between the first round roller 201 and the second round roller 203 on the right side. When the cloth is completely dyed, when the adjusting bolt is turned to reset it, the hydraulic oil in the second liquid guide tube 702 flows in the opposite direction, the telescopic end of the sixth telescopic rod 701 contracts and drives the two limit bent rods 703 to move and reset, and all parts are restored to their initial positions.
