[0003] The conventional fabric printing process includes several steps such as pre-treatment of the cloth, sizing and printing, and color fixing and washing. However, when the cloth enters the steamer and printing equipment, it will absorb moisture. The humidity in the steamer is generally set to a constant level, but when the cloth passes through the steamer, the moisture absorption of the cloth will cause the humidity in the steamer to fluctuate, resulting in inconsistent moisture absorption of the cloth and color difference in the print, affecting the printing effect.

DETAILED DESCRIPTION

[0038] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 6 As shown, a cloth humidifier comprises a frame 1, a feeding assembly 2 and a lowering assembly 3 are respectively arranged on two symmetrical sides of the frame 1, and a plurality of humidifying zones located between the feeding assembly 2 and the lowering assembly 3 are formed in the frame 1;

[0040] There is a partition between adjacent humidification zones, and a sealing window assembly for sealing the humidification zone is fixedly connected to the frame 1, and the sealing window assembly includes a fixed sealing plate and a movable sealing window, and a plurality of fixed sealing plates and movable sealing windows are respectively arranged on each side of the humidification zone, and at least one movable sealing window is arranged on the side of the humidification zone to form an entrance and exit connecting the humidification zone. In this embodiment, the fixed sealing plate uses tempered glass to seal the top and bottom of the humidification zone, and the two sides of the loading assembly 2 and the unloading assembly 3 on the frame 1 and between two adjacent humidification zones are used as The role of the interval, the size of the fixed sealing plate of the interval is smaller than the fixed sealing plate of the outside, the top of the fixed sealing used to achieve the interval is located below the upper steering shaft 4, and the adjacent side walls between the loading assembly 2 and the unloading assembly 3 on the frame 1 are provided with movable sealing windows. In this embodiment, the movable sealing windows use double-track sliding windows. When the double-track sliding windows are unfolded, each humidification interval is closed. When the double-track sliding windows are in an overlapping state, a passage for personnel to enter and exit the humidification interval is formed between the double-track sliding windows and the frame 1, which is convenient for personnel to operate in the humidification area when operating the cloth loading;

[0041] like Figure 4As shown, each humidifying zone is provided with a plurality of upper steering shafts 4 and lower steering shafts 5 located on the frame 1, and the upper steering shafts 4 and the lower steering shafts 5 are sequentially staggered along the cloth conveying direction to form a tortuous cloth feeding track, and the frame 1 is provided with a first driving mechanism 6 for driving the plurality of upper steering shafts 4 to rotate synchronously. In this embodiment, the first driving mechanism 6 includes a plurality of double-groove pulleys 61 connected to the upper steering shafts 4, and adjacent double-groove pulleys 61 are connected in transmission, and the double-groove pulleys 61 located at the head and tail are connected to a reduction motor 62 through a belt, and the double-groove pulleys connected thereto are driven by the reduction motor 62. 61, since the adjacent double-groove pulleys 61 are connected in sequence by belts, when the reduction motor 62 is started, all the double-groove pulleys 61 rotate synchronously under the drive of the reduction motor 62, and in this embodiment, the reduction motor 62 is electrically connected to the controller, and the speed of the reduction motor 62 can be adjusted by the frequency modulation of the controller. In this embodiment, the reduction motors 62 equipped in each humidification area are independent of each other, or interconnected through the controller, so that the tension of the cloth can be adjusted when the speed difference of the reduction motor 62 in each humidification area acts on the cloth;

[0042] The frame 1 is rotatably connected with a plurality of widening rollers 7 spaced apart between the upper steering shafts 4. The frame 1 is provided with a second driving assembly 8 for driving the plurality of widening rollers 7 to rotate. The second driving assembly 8 is used to drive the plurality of widening rollers 7 to rotate in the opposite direction of the rotation direction of the upper transmission shaft. The second driving assembly 8 includes a plurality of multi-groove pulleys 81 connected to the lower steering shaft 5. Adjacent multi-groove pulleys 81 are transmission-connected. The multi-groove pulleys 81 at the head and tail are connected to a direct-drive motor 82 via a belt. In this embodiment, two belt grooves of the multi-groove pulley 81 are selected, and two adjacent multi-groove pulleys are connected. 81 are connected to each other through belts, so that multiple widening rollers 7 are driven by a self-driving motor to rotate synchronously. In this embodiment, the self-driving motor also adopts a servo motor, which is connected to the controller through a frequency converter to achieve frequency conversion through the adjustment of the controller, so as to adjust the rotation speed of the widening roller 7, which can efficiently widen the passing cloth and ensure that the cloth remains neat when passing through the humidification area. In addition, a group of self-driving motors and reduction motors 62 are respectively set in each humidification interval, and the tension of the cloth in the humidification area can be further adjusted by adjusting them separately.

[0043] like Figure 3 and Figure 6As shown, the feeding assembly 2 is provided with a self-correcting mechanism and a tension adjustment mechanism, wherein the self-correcting mechanism is used to adjust the cloth to enter the humidification zone in the center position of the frame 1, and the self-correcting mechanism includes two guide seats 91 fixedly connected to the frame 1, and a support seat 92 is slidably connected to the guide seat 91, and at least two correcting rollers 93 are rotatably connected to the adjacent support seats 92, and the two guide seats 91 are fixedly connected with synchronously driven telescopic cylinders 94. When the corresponding cloth deviates from the center position, the two telescopic cylinders 94 are synchronously adjusted, and the support seat 92 is slid along the guide seat 91 by extending one of the telescopic cylinders 94 and contracting the other telescopic cylinder 94, so that the support seat 92 slides along the guide seat 91, and the correcting roller 93 is tilted and adjusted according to the direction of the cloth deviation, thereby achieving the purpose of correcting the deviation.

[0044] Rack 1 is equipped with:

[0045] A plurality of linear speed sensor groups, the linear speed sensor groups are used to obtain the linear speed of the cloth in the feeding component 2, the humidifying zone and the unloading component 3, and output a linear speed signal as an analog signal;

[0046] A plurality of tension sensors, the tension sensors are used to obtain the tension of the cloth in the feeding component 2, the humidifying zone and the unloading component 3, and output a tension signal as an analog signal;

[0047] A plurality of infrared sensors are arranged in an array on the self-correcting mechanism, and respond to optical shielding to reflect whether the cloth is in the middle position. A plurality of detection rods 10 are fixedly connected to the frame 1, and a gap for accommodating the cloth to pass through is provided between adjacent detection rods 10. The infrared sensor array is arranged on the detection rod 10. Specifically, the infrared sensor is arranged on the detection rod 10 located at the bottom, and the detection rod 10 located at the top is equipped with an infrared transmitter arranged corresponding to the infrared sensor. In this embodiment, a plurality of infrared sensors are arranged at intervals of 2 cm. When the cloth passes through the two detection rods 10, the infrared signal is shielded, and the infrared sensor The device is connected to the controller through a counting circuit. When the infrared sensor does not receive the infrared signal, it outputs a high-level digital signal to the counting circuit. The counting circuit determines the degree of deviation of the cloth by counting the number of infrared sensors, and can also roughly estimate the width of the cloth by the number of unreceived infrared sensors, thereby effectively avoiding the deviation of the cloth and the folding overlap that affects the humidification effect. When the number of detection signals received by the infrared sensors on both sides of the cloth is inconsistent, it reflects that the cloth has deviated from the center position. According to the signal conditions of the infrared sensors on both sides of the cloth, the drive signal is output to the self-correcting mechanism.

[0048] In this embodiment, the horizontal height of the expansion roller 7 is lower than the upper steering shaft 4. After the cloth passes through the upper steering shaft 4, the expansion roller 7, and the lower steering shaft 5 in sequence, it passes around the next adjacent upper steering shaft 4 and repeats in sequence to form a tortuous cloth feeding trajectory. When the cloth passes through the upper steering shaft 4, the reduction motor 62 drives several upper steering shafts 4 to move synchronously, so that the cloth moves in sequence from the upper material component 2 to the lower material component 3 under the driving action of the upper steering shaft 4. Specifically, when passing through each humidification interval, the expansion roller 7 is set to be driven at high speed by the self-driving motor, so that the cloth after passing through the upper steering shaft 4 can be expanded and smoothed, and then the smoothed cloth is displaced to the lower steering shaft 5, thereby achieving uniform and sufficient humidification.

[0049] like Figure 2 As shown, the feeding assembly 2 includes a plurality of cloth guide rollers 21 which are rotatably connected to the frame 1 in sequence along an inclined path, and the cloth guide rollers 21 at the highest horizontal height are at the same horizontal height as the self-correcting mechanism. In the present embodiment, the cloth guide rollers 21 are all rotatably connected to the frame 1, so that the cloth can have good neatness when it is winding around the plurality of cloth guide rollers 21, and the rotatable connection method can reduce the friction between the cloth and the guide rollers, thereby suppressing the deviation of the cloth when the force is unevenly applied, and the cloth guide rollers 21 at the highest horizontal height and the self-correcting mechanism are at the same horizontal height, so that the cloth fed by the feeding assembly 2 can be smoothly conveyed to the self-correcting mechanism, and the unloading assembly 3 in the present application includes a swing rod rotatably connected to the frame 1, and a limit rod is commonly connected between the two swing rods, and the limit rod is realized when the cloth is winding around the two swing rods in sequence When the limit rod is used, it is ensured that the cloth is limited during the reciprocating swing of the swing rod, thereby realizing the folding of the cloth along with the swing amplitude, and the frame 1 is also rotatably connected to a power roller located just above the swing rod, and the outer surface of the power roller is covered and wrapped with a rough bread roller belt to realize the stretching and unloading of the humidified cloth, and the frame 1 is also rotatably connected to a bidirectional threaded roller, which is also a kind of expansion roller 7, and is connected and driven by a motor and a pulley mechanism to realize the synchronous movement of the bidirectional threaded roller and the power roller. However, in this embodiment, the gears fixedly connected to the ends of the bidirectional threaded roller and the power roller are respectively located on the inner and outer rings of the same belt and remain in a meshing state, so that the power roller and the bidirectional threaded roller turn in opposite directions, so as to ensure that the cloth is in a neat state during the swing amplitude unloading and eliminate the edge frills.

[0050] like Figure 1As shown, a front tension roller 11, a middle tension roller 12 and a rear tension roller 13 are respectively provided on the frame 1. The front tension roller 11 is arranged between the feeding component 2 and the humidification area, the middle tension roller 12 is arranged at the middle section of the adjacent frames 1 or between the adjacent humidification areas, and the rear tension roller 13 is arranged between the unloading component 3 and the humidification area. Specifically, the rear tension roller 13 is arranged between the bidirectional threaded roller and the power roller, and the tension of the cloth during unloading can be retrieved through the rear tension roller 13. In this embodiment, a humidity sensor vertical to the cloth is provided on the frame 1.

[0051] The control process includes: the cloth passes through the feeding component 2 and the humidification area in sequence until the unloading component 3. When the cloth passing through the feeding component 2 passes through the self-correcting mechanism, the position of the cloth in the self-correcting mechanism is adjusted:

[0052] 1) The width of the self-correcting mechanism of the cloth is detected by infrared sensors, and the number of infrared sensors located between the edge of the cloth and both sides of the frame 1 that are not blocked by the cloth is obtained, and the difference in the number of infrared sensors on both sides of the cloth is recorded to provide feedback on the deviation degree of the cloth;

[0053] 2) Calculate the degree of self-correction. Set the number of unobstructed infrared sensors on the left side of the cloth as A1, and the number of unobstructed infrared sensors on the right side of the cloth as A2. Then calculate the difference in the number of infrared sensors on both sides of the cloth as A∆=A2-A1. The required offset distance L of the self-correction mechanism is: L=2*sin(α / 2). Output the offset signal of the required offset distance L as an analog signal, where α is the tilt angle of the offset.

[0054] 3) Self-correction action: after receiving the deviation signal through the encoder / decoder, the telescopic cylinder 94 in the self-correction mechanism performs telescopic action according to the value of the deviation signal to adjust the inclination angle of the two deviation correction rollers 93;

[0055] 4) Deviation correction: During the self-deviation correction operation, the number of infrared sensors on both sides of the cloth that are not blocked by the cloth is detected synchronously. When the number of infrared sensors on both sides of the cloth that are not blocked by the cloth is the same, the self-deviation correction action can be stopped; when the number of infrared sensors on both sides of the cloth that are not blocked by the cloth is inconsistent, the self-deviation correction action is maintained.

[0056] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
