Description

Technical Field

[0001] The present invention relates to the technical field of batik processing, and particularly to a telescopic drying device for batik processing. Background Art

[0002] Batik is a printing and dyeing technique in which a wax knife is dipped in molten wax to paint patterns on fabric. Since it is generally carried out manually, the batik fabric is commonly used for the manual production of clothing and the decoration of ornaments. After the batik of the fabric is completed, it generally needs to be immersed and washed. After the immersion and washing are completed, in order to facilitate the rapid drying of the fabric, the fabric needs to be placed inside a drying device for drying to achieve the effect of drying it.

[0003] A telescopic drying and airing device for batik processing with the publication number of CN112797752A belongs to the field of batik processing, including a base. The bottom of the base is fixedly connected with rollers, and the side of the base is fixedly connected with a support plate. An adjusting screw rod is threadedly sleeved inside the support plate, and the bottom end of the adjusting screw rod is fixedly connected with an anti-slip plate; by setting a support sleeve, an adjusting rod, a fixed sleeve, a movable spring, a rubber pad and an electromagnet, during the batik processing, the height of the drying and airing device can be telescopically adjusted according to the length of the batik fabric.

[0004] A drying cabinet for batik processing with the publication number of CN222317524U includes a drying main body which is integrally arranged in a cabinet structure, and heating wires are arranged around its inner wall for heating and drying inside the drying main body; a cover plate which is rotatably opened on the surface of the drying main body through a hinge for placing and taking the fabric; and also includes a placing mechanism which is arranged at equal intervals inside the drying main body; a moving mechanism which is arranged inside the placing mechanism. When the fabric is placed on the placing mechanism, it can be laid flat on the middle placing mechanism and the outer placing mechanism respectively, or can be vertically placed in the middle of the middle placing mechanism and the outer placing mechanism for drying, which is convenient to adjust the placing position according to the different sizes of the dried fabric, so that the contact space between the fabric and the internal hot air is larger and the drying efficiency is better.

[0005] Regarding the above - related solutions, the lateral position adjustment of the outer placement mechanism and the middle placement mechanism is achieved through the cooperation of a drive motor, a lead screw, a moving seat, an intermediate rack, an outer rack, and a meshing gear. However, during this process, due to the lack of positioning of the fabric on the outer placement mechanism and the middle placement mechanism, mechanical vibration or air flow disturbance easily causes the fabric to shift and slip, affecting the drying stability. Moreover, when adjusting the lateral position, the drive motor needs to frequently reverse to drive the lateral position adjustment of the outer placement mechanism and the middle placement mechanism, resulting in increased brush wear, overheating of the winding, shortened service life, and high energy consumption. And the one - way position adjustment is difficult to dynamically adjust the fabric tension distribution, easily generating wrinkles and uneven heating, causing local overheating and damaging the fibers, and unable to adapt to the drying requirements of fabrics with different thicknesses / densities. In addition, it lacks a mechanism for automatically blocking power transmission when the cover plate is opened, and easy to cause safety hazards when the drive motor is accidentally started, restricting the batik processing efficiency and finished product quality.

Semi - tooth discs are arranged on the outer sides of the two first rotating shafts, and a full - tooth disc meshing with the semi - tooth discs is arranged at the rear end of one of the second rotating shafts. A guide groove is opened on the inner surface of the drying box.

[0012] Preferably, the front end of the tooth plate is symmetrically provided with plug-in grooves, and the support frame and the tooth plate form a snap-fit ​​structure through the plug-in grooves.

[0016] Preferably, a second slide groove is equidistantly provided at the rear end of the inner surface of the drying box, and a second slide block extending to the inner side of the second slide groove is symmetrically provided at the rear end of the tooth plate.

[0017] Preferably, a circulating drying mechanism is provided through the inner side of the drying box, and the circulating drying mechanism includes an air supply box connected to the bottom end of the inner surface of the drying box, and through holes are evenly opened on the top of the air supply box.

[0018] Preferably, a heating box and a fan connected by pipes are installed in sequence from left to right on the mounting plate on one side of the drying box, electric heating tubes are installed equidistantly on the side of the heating box close to the fan, a branch pipe connected to the air supply box is connected to the side of the fan away from the heating box through a pipe, and a corrugated hose is connected between the heating box and the drying box.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the synergistic effect of the electric push rod, anti - detachment mechanism, displacement mechanism and cyclic drying mechanism, the present invention realizes the automatic opening and closing of the front cover body, cloth positioning and energy - efficient cloth drying. In the anti - detachment mechanism, when the electric push rod contracts, it drives the sliding block to move horizontally through the first linkage plate, and the second linkage plate drives the lifting plate to press down, so that the support frame is engaged with the toothed plate and the anti - detachment roller abuts against the cloth, realizing the rapid automatic positioning of multiple pieces of cloth, avoiding deviation and slippage caused by mechanical vibration or air flow disturbance, the opening and closing of the front cover body are linked with the positioning action, and the operation efficiency is improved; The displacement mechanism adopts a motor to drive in a constant - speed one - way manner, drives the misaligned semi - toothed disk to rotate through a pulley group, and drives the second rotating shaft to rotate forward and backward through the engagement of the full - toothed disk. Combining the transverse displacement of the toothed plate and the longitudinal displacement of the side plate, the tension distribution of the cloth is dynamically adjusted, reducing wrinkles and enhancing the uniformity of hot - air contact, offsetting the cumulative effect of unidirectional friction, and the periodic displacement avoids local overheating damage to fibers, adapting to different cloth thicknesses / densities to shorten the drying cycle; The cyclic drying mechanism forms a closed - loop system through the layered air - supply box and the return air duct, improving the uniformity of hot air and the utilization rate of heat energy. Cooperating with the multi - directional movement of the displacement mechanism, the water evaporation rate is increased. When the door is opened, the gear is automatically disengaged from the toothed plate, blocking the mis - triggered power transmission of the motor and eliminating the risk of abnormal displacement of the idler roller, ensuring the safe and efficient access of materials.

[0020] 1. For the telescopic drying device for batik processing, during the process of making the electric push rod work and contract, the front cover body can be automatically closed to save manpower. Since the sliding block and the front cover body are linked through the first linkage plate, and the sliding block is slidably connected to the drying box, the first linkage plate pushes the sliding block to move horizontally. Since the lifting plate and the sliding block are linked through the second linkage plate, the lifting plate moves vertically downward until the support frame is engaged with the toothed plate through the insertion slot, and at the same time, the anti - detachment roller abuts against the cloth at the top of the idler roller, so as to realize the automatic and stable positioning of multiple pieces of cloth, thus avoiding the deviation or slippage of the cloth caused by mechanical vibration or air flow disturbance during movement, further ensuring the stability of the drying process, and greatly improving the efficiency of cloth positioning. In addition, after the front cover body is opened, the rapid automatic release of cloth positioning can be realized to take down the dried cloth, which is more convenient to use.

[0021] 2. When the lifting plate moves vertically downward, the telescopic drying device for batik processing can control the gear to engage with the toothed plate and make the support frame engage with the toothed plate. When the motor works, the output end of the motor drives the two rotating shafts I and the misaligned semi-toothed discs to rotate synchronously under the action of the pulley group I. Since the full-toothed disc is meshed and connected with the semi-toothed disc, the full-toothed disc, the rotating shaft II, and the gear rotate reciprocally in positive and negative directions together, and the continuous and stable operation of the rotating shaft II can be realized without changing the rotation direction of the motor. At the same time, the motor runs at a constant speed in one direction, reducing the risk of brush wear and winding overheating, prolonging the service life of the motor and reducing power consumption. And because the gear is meshed and connected with the toothed plate, the toothed plate and the roller drive the fabric to make reciprocating lateral displacements together. At the same time, since the side plate is slidably connected to both the drying box and the toothed plate, the side plate and the roller drive the fabric to make reciprocating longitudinal displacements during the reciprocating lateral displacements, dynamically adjusting the fabric tension distribution by coordinating the lateral and longitudinal displacements, reducing wrinkles and optimizing the uniformity of hot air contact, offsetting the cumulative effect of unilateral friction to maintain the unfolded state, avoiding local overheating damage to fibers by periodic displacements, adapting to different fabric thicknesses / densities to shorten the drying cycle. In addition, by means of door opening linkage, the gear is disengaged from the toothed plate, effectively blocking the power transmission when the motor is accidentally triggered, eliminating the risk of abnormal displacement of the roller, and ensuring the stability of material access and storage.

[0022] 3. The present invention is provided with a circulating drying mechanism. The hot air heated in the heating box is sent into the branch pipes by the blower and then into the air supply box through the branch pipes, so that the air supply box can evenly send hot air into the drying box through the through holes at the top, avoiding local temperature differences, facilitating uniform heating of the fabric, ensuring the drying effect, and the hot air flowing to the top is conveyed to the heating box through the corrugated hose for reheating and then sent into the drying box again. By this way, the energy consumption of repeated heating of the heating box can be reduced, playing a role in saving heat energy. In addition, the flowing hot air can improve the drying effect to a certain extent and ensure the drying uniformity. Brief Description of the Drawings

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0035] Please refer to Figure 1 、 Figure 2 and Figures 8 - 10, the present invention provides a technical solution: a telescopic drying device for batik processing, including a drying box 1 and a front cover body 2 for closing the drying box 1. The drying box 1 includes a fixed box 102 and a movable box 101 slidably sleeved outside the fixed box 102. The front cover body 2 includes a fixed cover 202 and a movable cover 201 slidably sleeved outside the fixed cover 202. Hydraulic cylinders 3 are installed between the fixed box 102 and the movable box 101 and between the fixed cover 202 and the movable cover 201. A roller 6 is movably connected to the middle inside the drying box 1. The symmetrically arranged rollers 6 can leave a large amount of space between the fabrics, facilitating the circulation of air to ensure the drying effect.

[0036] During specific implementation, in order to dry fabrics of different lengths, the hydraulic cylinder 3 is operated to drive the movable box 101 and the movable cover 201 to move in the vertical direction, so as to realize the telescopic adjustment of the drying box 1 and the front cover body 2, enabling the drying device to be applicable to the drying operation of fabrics of different lengths and expanding the scope of application.

[0037] Refer to Figure 1 、 Figures 4 - 6 and Figures 8 - 10 It can be known that an electric push rod 7 and an anti-disengagement mechanism 4 are arranged between the drying box 1 and the front cover body 2. The electric push rod 7 is hinged to both the drying box 1 and the front cover body 2. The anti-disengagement mechanism 4 includes a sliding block 402 movably connected to the drying box 1 and a lifting plate 406. Linking plates one 401 and linking plates two 405 are respectively hinged between the sliding block 402 and the front cover body 2 and the lifting plate 406. The front end of the lifting plate 406 is movably connected to a support frame 409, and a support spring 410 at the bottom end of the support frame 409 is connected to an anti-disengagement roller 411.

[0038] During specific implementation, since the sliding block 402 and the front cover body 2 are linked by the linking plate one 401, and the sliding block 402 and the drying box 1 are slidably connected through a slider one 403 and a chute one 404, when the electric push rod 7 works and contracts, the front cover body 2 can be automatically closed to save labor. At the same time, the linking plate one 401 pushes the sliding block 402 to move horizontally. Since the lifting plate 406 and the sliding block 402 are linked by the linking plate two 405, the lifting plate 406 moves vertically downward until the support frame 409 is clamped with the toothed plate 509 through the insertion slot 413, and the support spring 410 is stressed and contracted. At the same time, the anti-disengagement roller 411 abuts against the fabric at the top of the roller 6 to realize the automatic and stable positioning of multiple fabrics, thus avoiding the deviation or slippage of the fabric caused by mechanical vibration or air flow disturbance during movement, ensuring the stability of the drying process, greatly improving the efficiency of fabric positioning. In addition, after the front cover body 2 is opened, the rapid automatic release of fabric positioning can be realized to facilitate the removal of the dried fabric, which is more convenient to use.

[0039] A slide groove 404 is symmetrically provided at the top of the inner side of the drying box 1, and a slider 403 is welded at the top of the sliding block 402 to form a sliding structure with the slide groove 404. The cooperation between the slide groove 404 and the slider 403 can support and guide the sliding block 402, so that the sliding block 402 can only make a linear motion in the horizontal direction to prevent deviation.

[0040] A return spring 412 is equidistantly arranged between the lifting plate 406 and the drying box 1, and a guide telescopic rod connected to the lifting plate 406 and the drying box 1 is arranged inside the return spring 412. When the front cover 2 is automatically opened, the lifting plate 406 can be quickly moved vertically upward with the assistance of the return spring 412, so as to improve the convenience of the lifting plate 406 to rise and reset, and save more effort. Moreover, through the guiding effect of the guide telescopic rod, the lifting plate 406 is only moved in the vertical direction to prevent deviation.

[0041] The front end of the tooth plate 509 is symmetrically provided with an insertion groove 413, and the support frame 409 and the tooth plate 509 form a clamping structure through the insertion groove 413. By plugging the support frame 409 and the insertion groove 413, the support frame 409 and the tooth plate 509 can form an integrated structure, so that the support frame 409 can move together when the tooth plate 509 is displaced, so as to ensure the positioning effect of the anti-slip roller 411 on the cloth;

[0042] A limiting telescopic rod that passes through the supporting spring 410 is connected between the supporting frame 409 and the anti-slip roller 411, a limiting groove 407 is provided at the front end of the lifting plate 406, and a limiting rod 408 that forms a sliding structure with the limiting groove 407 is provided at the top of the supporting frame 409. Through the cooperation between the limiting groove 407 and the limiting rod 408, a supporting and guiding role can be played for the supporting frame 409, so that when the supporting frame 409 and the tooth plate 509 form an integrated structure, they can move synchronously with the tooth plate 509, and through the action of the supporting spring 410, the anti-slip roller 411 and the cloth are always in a tight state when the roller 6 is displaced longitudinally.

[0043] See also Figure 1 , Figures 3 - 6 and Figures 8 - 10It can be seen that a displacement mechanism 5 for enabling the transverse and longitudinal displacement of the fabric is provided between the idler roller 6 and the lifting plate 406. The displacement mechanism 5 includes a first rotating shaft 502, a second rotating shaft 506 connected to the lifting plate 406 through bearings, a toothed plate 509 movably connected to the drying box 1, and a side plate 514 connected to the idler roller 6. Semi-toothed discs 504 are arranged on the outer sides of the two first rotating shafts 502, and the two semi-toothed discs 504 are arranged in a staggered manner. A full-toothed disc 505 meshing with the semi-toothed disc 504 is arranged at the rear end of one second rotating shaft 506, and a gear 508 meshing with the toothed plate 509 is arranged at the front end of the second rotating shaft 506. A second belt pulley set 507 is connected between every two second rotating shafts 506. A motor 501 connected to one first rotating shaft 502 through a coupling is installed at the bottom end of the lifting plate 406. A first belt pulley set 503 located at the rear end of the semi-toothed disc 504 is connected between the two first rotating shafts 502. A guide groove 516 is formed on the inner surface of the drying box 1, and a guide block 515 forming a sliding structure with the guide groove 516 is arranged at the rear end of the side plate 514. By the transverse movement of the toothed plate 509 and the drive of the guide groove 516, the idler roller 6 is longitudinally moved, eliminating the need for additional drive devices and reducing energy consumption;

[0044] During specific implementation, when the lifting plate 406 moves vertically downward, the gear 508 can be controlled to engage with the toothed plate 509, and the support frame 409 can be clamped with the toothed plate 509. When the motor 501 operates, the output end of the motor 501 drives the two first rotating shafts 502 and the stagger - arranged semi - tooth discs 504 to rotate synchronously under the action of the first pulley group 503. Since the full - tooth disc 505 is meshed and connected with the semi - tooth disc 504, the full - tooth disc 505, the second rotating shaft 506, and the gear 508 rotate reciprocally in positive and negative directions together, and there is no need to change the rotation direction of the motor 501, so as to be able to drive the second rotating shaft 506 to work continuously and stably. At the same time, the motor 501 operates at a constant speed in one direction, avoiding overheating of the winding and wear of the carbon brush caused by frequent starting, stopping, and commutation, which is beneficial to extending the service life of the motor 501, reducing energy consumption, and enhancing stability. And because the gear 508 is meshed and connected with the toothed plate 509, and the toothed plate 509 is slidably connected with the drying box 1 through the second chute 511 and the second slider 510, the toothed plate 509 and the roller 6 drive the fabric to make reciprocating lateral displacement together. At the same time, because the side plate 514 is slidably connected with the drying box 1 and the toothed plate 509 through the guide block 515, the guide groove 516, the limiting plate 512, and the limiting groove respectively, the side plate 514 and the roller 6 drive the fabric to make reciprocating longitudinal displacement during the reciprocating lateral displacement process. Through the synergistic effect of the lateral and longitudinal movements, the tension distribution of the fabric can be dynamically adjusted, the generation of wrinkles can be reduced, and the spatial attitude of the fabric can be changed, promoting more sufficient contact of hot air with different regions, reducing the probability of local uneven heating or residual moisture, enhancing the convection effect of hot air, accelerating the moisture evaporation rate, shortening the overall drying cycle. At the same time, the multi - direction movement offsets the cumulative effect of the friction force in a single direction, maintaining the stable and unfolded state of the fabric during movement, and the longitudinal periodic displacement can prevent the surface of the fabric from being fixed at the same position for a long time, reducing the risk of fiber damage caused by concentrated hot air. Through different movement trajectories, fabrics with different thicknesses or densities can be adapted, avoiding the repeated drying requirements caused by differences in heat conduction. In addition, by opening the door linkage, the gear 508 is disengaged from the toothed plate 509, effectively blocking the power transmission when the motor 501 is accidentally triggered, eliminating the risk of abnormal displacement of the roller 6, and ensuring the stability of material access and storage;

[0045] A limiting plate 512 is arranged at the bottom end of the toothed plate 509. Second limiting grooves 513 which form a sliding structure with the limiting plate 512 are symmetrically opened at the top end of the side plate 514, and the height of the limiting plate 512 is higher than that of the second limiting grooves 513. Through the cooperation of the limiting plate 512 and the second limiting grooves 513, when the side plate 514 moves longitudinally in a reciprocating manner, the side plate 514 and the toothed plate 509 are always an integral structure, enabling the side plate 514 to move laterally following the toothed plate 509;

[0046] At the rear end of the inner surface of the drying box 1, sliding grooves two 511 are equidistantly arranged. At the rear end of the toothed plate 509, sliding blocks two 510 extending to the inside of the sliding grooves two 511 are symmetrically arranged, which can play a role in supporting and limiting the toothed plate 509, so that the toothed plate 509 can only make reciprocating movements in the horizontal direction.

[0047] Refer to Figure 2 , Figure 7 , Figure 9 and Figure 10 It can be seen that a circulating drying mechanism 8 is arranged through the inside of the drying box 1. The circulating drying mechanism 8 includes a air supply box 805 connected to the bottom end of the inner surface of the drying box 1. Through holes 806 are evenly arranged at the top end of the air supply box 805. On the mounting plate on one side of the drying box 1, a heating box 801 and a blower 803 connected by a pipeline are sequentially installed from left to right. On the side of the heating box 801 close to the blower 803, electric heating tubes 802 are equidistantly installed. On the side of the blower 803 away from the heating box 801, a branch pipe 804 connected to the air supply box 805 is connected by a pipeline. A corrugated hose 807 is connected between the heating box 801 and the drying box 1;

[0048] During specific implementation, the hot air heated by the electric heating tubes 802 in the heating box 801 is sent into the branch pipe 804 by the blower 803, and is sent into the air supply box 805 through the branch pipe 804, so that the air supply box 805 can evenly send hot air into the drying box 1 through the through holes 806 at the top end, so as to avoid local temperature differences, facilitate the uniform heating of the fabric, ensure the drying effect, and the hot air flowing to the top is transported to the heating box 801 through the corrugated hose 807, so that it can be sent into the drying box 1 again after heating. By this method, the energy consumption of repeated heating of the heating box 801 can be reduced, and the role of saving heat energy can be achieved. In addition, the flowing hot air can improve the drying effect to a certain extent and ensure the drying uniformity.

[0049] Working principle: When using this telescopic drying device for batik processing, lay multiple pieces of batiked and rinsed fabrics on the surfaces of multiple groups of symmetrically arranged idler rollers 6 in sequence. Then, make the electric push rod 7 work and contract, so that it drives the front cover body 2 to operate and automatically close. During this process, through the linkage between the sliding block 402 and the front cover body 2 and the sliding between the sliding block 402 and the drying box 1, the linkage plate one 401 pushes the sliding block 402 to move horizontally. Through the linkage between the lifting plate 406 and the sliding block 402, the lifting plate 406 moves vertically downward until the support frame 409 and the toothed plate 509 are clamped through the insertion slot 413, and the gear 508 meshes with the toothed plate 509. At the same time, the anti-drop roller 411 abuts against the fabric at the top of the idler roller 6, so as to realize the automatic and stable positioning of multiple pieces of fabrics. At this time, start the motor 501, so that the output end of the motor 501 drives two rotating shafts one 502 and the staggered half-toothed discs 504 to rotate synchronously under the action of the pulley group one 503. Through the meshing between the full-toothed disc 505 and the half-toothed disc 504, the full-toothed disc 505 makes reciprocating forward and reverse rotations, and under the action of the pulley group two 507, multiple rotating shafts two 506 and the gear 508 rotate forward and reverse together. Through the meshing between the gear 508 and the toothed plate 509 and the sliding between the toothed plate 509 and the drying box 1, the toothed plate 509 and the idler roller 6 drive the fabric to make reciprocating horizontal displacements together. At the same time, through the sliding between the side plate 514 and the drying box 1 and the toothed plate 509, the side plate 514 and the idler roller 6 drive the fabric to make reciprocating longitudinal displacements during the reciprocating horizontal displacements, so as to optimize the uniformity of hot air contact and offset the cumulative effect of unilateral friction to maintain the unfolded state;

[0050] During this process, the hot air heated by the electric heating tube 802 in the heating box 801 is sent into the branch pipe 804 by the blower 803, and is sent into the air supply box 805 through the branch pipe 804, so that the air supply box 805 can evenly send hot air into the drying box 1 through the through holes 806 at the top, so as to ensure the drying effect, and the hot air flowing to the top is transported to the heating box 801 through the corrugated hose 807, so as to be sent into the drying box 1 again after heating, so as to reduce the energy consumption of repeated heating of the heating box 801;

[0051] After the fabrics are dried, make the electric push rod 7 work and extend, so that it drives the front cover body 2 to operate and automatically open. During this process, the lifting plate 406 moves vertically upward under the auxiliary action of the return spring 412, so that the anti-drop roller 411 is separated from the fabric and the gear 508 is separated from the toothed plate 509, so that the dried fabrics can be taken out and the fabrics to be dried can be placed again. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
