Description

Technical Field

[0001] This application relates to the field of pad dyeing machines, and more particularly to a drying device for pad dyeing machines. Background Technology

[0002] Pad dyeing is a dyeing method in which the fabric is immersed in dye solution and then subjected to pressure from rollers to force the dye solution into the fabric and remove excess solution. In pad dyeing, the fabric is briefly immersed in dye solution, and then immediately pressed with rollers to squeeze the dye solution into the fabric's structure and remove excess dye solution, resulting in a uniform distribution of dye on the fabric.

[0003] Currently, Chinese utility model patent CN220550344U discloses a high-efficiency drying mechanism for a tie-dyeing machine, including a casing. A feeding roller is installed on one side of the casing, and a drying assembly is installed inside the casing. A fixing plate is fixedly connected inside the casing, and a pressing assembly is installed inside the fixing plate. This high-efficiency drying mechanism for the tie-dyeing machine includes a motor, a rotating rod, a first bevel gear, a second bevel gear, a lead screw, a fan, a slide, and a slider. Starting the motor drives the rotating rod to rotate, which in turn drives the first bevel gear to rotate. The rotation of the first bevel gear, in turn, drives the second bevel gear to rotate, thereby causing the fan on the lead screw to move up and down. The motor is a double-headed motor, allowing both fans to blow air onto the fabric being dried. This combination of drying and air drying accelerates the drying process and improves the drying efficiency of the mechanism.

[0004] During the drying process, the fan needs to provide continuous ventilation in order to increase the air circulation speed inside the machine and increase the contact between the fabric and the hot air. However, the noise generated by the fan during operation can easily affect the surrounding environment. Summary of the Invention

[0005] In order to reduce the noise generated during the drying process of the drying equipment, this application provides a drying device for a dyeing machine.

[0006] This application provides a drying device for a dyeing machine, which adopts the following technical solution: A drying device for a dyeing machine includes a drying chamber, a heating component for heating the inside of the drying chamber, and a feeding component. The feeding component includes a feeding frame, a driving component, a tensioning component, and a swinging component. The tensioning component is used to keep the fabric at the feeding frame in a wide-width tensioned state. The driving component is used to transport the fabric on the feeding frame. The swinging component is used to drive the feeding frame to swing.

[0007] By adopting the above technical solution, the heating component heats the drying chamber, and the fabric inside the drying chamber moves via the drive component. The tensioning part tightens the fabric on the feeding frame, and the swinging component swings the feeding frame. During the swinging process of the feeding frame, the taut fabric swings with the feeding frame, and the fabric acts as a fan. The movement of the fabric causes the air inside the drying chamber to circulate rapidly, and the heat generated by the heating component quickly comes into contact with the fabric, achieving the drying effect. Furthermore, by using the swinging component to move the fabric, there is no need to use a fan to drive the air circulation inside the drying chamber, which greatly reduces the noise generated by the drying chamber and reduces noise pollution.

[0008] Optionally, the tensioning part includes two tensioning frames, two clamping pieces for holding the two sides of the fabric, a bidirectional screw, and a tensioning motor. The two tensioning frames are located on both sides of the fabric and are slidably connected to the feeding frame along the width direction of the fabric. The bidirectional screw is rotatably connected to the feeding frame. The two tensioning frames are respectively threaded to the threaded sections of the bidirectional screw with opposite directions of rotation. The tensioning motor drives the bidirectional screw to rotate.

[0009] By adopting the above technical solution, the tensioning part is used to tighten the fabric along the width direction. The worker first places the fabric between two clamping pieces, which clamp the two long sides of the fabric respectively. Then the worker starts the tensioning motor, which drives the bidirectional screw to rotate. The bidirectional screw drives the two tensioning frames to move away from each other. The movement of the tensioning frames away from each other causes the clamping pieces to move away from each other, and the width direction of the fabric is tightened, so that the fabric can play the function of a fan when the swinging part swings.

[0010] Optionally, the clamping member includes a conveyor belt, two conveyor rollers, several needle punches, two mating rollers, and a mating belt. The two conveyor rollers are distributed along the fabric conveying direction and are rotatably connected to the feeding frame. The conveyor belt is sleeved on the two conveyor rollers. Several needle punches are disposed on the outer side wall of the conveyor belt. The two mating rollers are distributed along the fabric conveying direction and are rotatably connected to the feeding frame. The mating belt is sleeved on the two mating rollers, and the needle punches penetrate the fabric and insert into the mating belt.

[0011] By adopting the above technical solution, the clamping parts are used to clamp the long side of the fabric. When the fabric needs to be tightened, the worker first places the two long sides of the fabric with the two clamping parts respectively. The worker first passes the fabric through the needles on the conveyor belt. The needles pierce the fabric and insert them into the mating belt. At this time, the long side of the fabric is clamped. The worker can then drive the bidirectional screw to rotate through the tensioning motor, so that the two tensioning frames move away from each other. The tensioning frames tighten the fabric along the width direction. Since the drive unit is used to drive the fabric conveyor, during the conveying process, the fabric and the needles work together to drive the conveyor belt to rotate. The mating belt moves with the conveyor belt under the action of the needles. The needles on the conveyor belt pierce the subsequent fabric and insert it into the mating belt.

[0012] Optionally, the tensioning frame is equipped with an adjusting component for adjusting the distance between the conveyor belt and the mating belt. The adjusting component includes two sliding blocks, two connecting rods, two mating blocks, two screws, and a dual-head motor. The two sliding blocks correspond one-to-one with the two conveyor rollers, and the sliding blocks are slidably connected to the tensioning frame along the thickness direction of the fabric. The two sliding blocks correspond one-to-one with the two conveyor rollers, and the conveyor rollers are rotatably connected to the sliding blocks. The two mating blocks correspond one-to-one with the two sliding blocks, and the mating blocks are slidably connected to the tensioning frame along the conveying direction of the fabric. The two connecting rods correspond one-to-one with the two sliding blocks, with one end of the connecting rod rotatably connected to the sliding block and the other end of the connecting rod rotatably connected to the mating block. The two screws correspond one-to-one with the two mating blocks, and the screws are rotatably connected to the tensioning frame. The mating blocks are threadedly connected to the screws. The dual-head motor is used to drive the two screws to rotate.

[0013] By adopting the above technical solution, since the needles need to pierce into the mating belt, the initial feeding of the fabric is relatively inconvenient. The operator can first start the dual-head motor, which drives two screws to rotate. The two screws drive two mating blocks to move closer or further apart. The mating blocks drive the connecting rod to rotate. The connecting rod drives two sliding blocks to move away from the mating roller. The conveyor roller rotates and is connected to the sliding blocks. When the conveyor roller moves away from the sliding blocks, the conveyor belt moves away from the mating belt, and the needles on the conveyor belt detach from the mating belt. This makes it easier for the operator to pierce the fabric into the needles. Then, the dual-head motor is started again, rotating in the opposite direction. The screws drive the mating blocks to move, and the mating blocks drive the connecting rod to move. The connecting rod moves the sliding blocks, and the sliding blocks drive the conveyor roller to move closer to the mating roller. The conveyor belt moves towards the mating belt, and the needles on the conveyor belt pierce into the mating belt, completing the feeding process.

[0014] Optionally, the driving component includes a driving roller, a driving motor, and a driven roller. The driving roller is rotatably connected to the tensioning frame, and the driving motor drives the driving roller to rotate. The driven roller and the driving roller respectively abut against two sides of the fabric.

[0015] By adopting the above technical solution, the driving component is used to drive the fabric conveying. The driving roller and the driven roller clamp the fabric. The driving motor drives the driving roller to rotate, and the driving roller drives the fabric to move. The driving component has a simple structure and is easy for workers to operate.

[0016] Optionally, the tensioning frame is provided with a limiting component that restricts the unidirectional rotation of the driven roller. The limiting component includes a ratchet, a pawl, and a limiting spring. The ratchet is disposed on the driven roller, the pawl is rotatably connected to the tensioning frame, and the limiting spring is used to engage the pawl with the ratchet.

[0017] By adopting the above technical solution, since the swinging component will drive the feeding frame to swing, the swinging of the feeding frame will pull the fabric at one end of the rotating axis of the feeding frame. The driven roller has no power source and is prone to rotating in the opposite direction with the pull of the fabric, causing the fabric to detach from the drive roller. The limiting component restricts the reverse rotation of the driven roller. When the fabric is subjected to a pulling force opposite to the conveying direction, the pawl is engaged with the pawl under the action of the limiting spring, and the driven roller cannot move in the opposite direction. The driven roller and the drive roller restrict the fabric from moving in the opposite direction to the conveying direction. When the drive motor drives the drive roller to rotate, the pawl on the limiting component cannot engage with the ratchet, thus realizing the unidirectional rotation of the driven roller.

[0018] Optionally, the drying chamber is also provided with an auxiliary component for winding up the fabric. The auxiliary component includes an auxiliary frame, two auxiliary rollers, and a coil spring. The auxiliary frame is rotatably connected to the drying chamber, the two auxiliary rollers are rotatably connected to the auxiliary frame, and the coil spring is used to drive the auxiliary frame to rotate, so that the fabric passes through the two auxiliary rollers.

[0019] By adopting the above technical solution, the fabric at the feed end of the drying box is pulled into the drying box by the swinging of the swinging component. The fabric will alternate between a taut and a loose state. The loose fabric is not easy to enter the feeding frame. When the fabric enters the drying box, it needs to pass through two auxiliary rollers. When the fabric is in a loose state, the coil spring will drive the auxiliary frame to rotate. The auxiliary frame will drive the two auxiliary rollers to rotate. The two auxiliary rollers will wind the fabric, reducing the loose state of the fabric in the drying box and making it easier for the fabric entering the feeding frame to be in a taut state. The auxiliary component reduces the situation of the fabric being in a loose state.

[0020] Optionally, the oscillating component includes an incomplete gear, an oscillating motor, an oscillating frame, a rack, and an oscillating gear. The oscillating frame is slidably connected to the drying chamber. The rack is parallel to the sliding direction of the oscillating frame and is disposed on the oscillating frame. The oscillating gear is disposed on the feeding frame and meshes with the rack. The inner sidewall of the oscillating frame is provided with locking teeth. The incomplete gear is disposed inside the oscillating frame and meshes with the locking teeth. The oscillating motor drives the incomplete gear to mesh.

[0021] By adopting the above technical solution, the swinging component is used to drive the feeding frame to swing. The swinging motor drives the incomplete gear to rotate. The incomplete gear meshes with the locking teeth on the swinging frame. The swinging frame moves back and forth under the meshing of the incomplete gear and the locking teeth. The swinging frame drives the rack to move. The rack drives the swinging gear to rotate back and forth. The swinging gear realizes the swinging of the swinging frame. The swinging frame causes the fabric to move. The swinging of the fabric acts as a fan to circulate the air in the drying chamber and improve the drying efficiency of the fabric.

[0022] Optionally, the heating assembly includes two heating elements, each corresponding to one of the two sides of the fabric. Each heating element includes a plurality of heating rods, which are distributed along the conveying direction of the fabric.

[0023] By adopting the above technical solution, two heating elements are used to heat both sides of the fabric. The heating rods are distributed along the conveying direction of the fabric, so that the fabric can be heated multiple times along the conveying direction, the heating is more uniform, and the heating effect of the fabric is improved.

[0024] Optionally, the drive roller is coaxial with the swing axis of the feeding frame.

[0025] By adopting the above technical solution, the drive roller and the feeding frame are coaxially arranged, which can reduce the relative movement of the fabric at the drive roller relative to the feeding frame during the oscillation of the feeding frame, and improve the reliability of the oscillation of the feeding frame.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The swinging component is used to swing the feeding frame. The taut fabric on the feeding frame acts as a fan to circulate the air in the drying chamber, increase the contact between the fabric and the hot air, improve the drying efficiency of the fabric, and reduce the noise of the drying chamber, thus reducing noise pollution. 2. The clamping piece is used to hold the two long sides of the fabric, so that the fabric is taut along the width direction; 3. The adjustable parts facilitate workers in placing the fabric between the conveyor belt and the mating belt, improving the speed of fabric loading and installation; 4. Auxiliary components are used to keep the fabric taut inside the drying oven; 5. The swing component is used to drive the feeding frame to swing back and forth. Attached Figure Description

[0045] The implementation principle of a drying device for a dyeing machine according to an embodiment of this application is as follows: Before using the drying device, the fabric needs to be loaded. The operator first starts the double-head motor 65, which drives two screws 64 to rotate. The two screws 64 drive the mating block 63 to move, and the mating block 63 drives two connecting rods 62 to rotate. The two connecting rods 62 drive the sliding block 61 to move away from the mating roller 54. The conveyor roller 52 on the sliding block 61 moves away from the mating roller 54. The operator places the fabric between the conveyor belt 51 and the mating block 63, and the needle 53 punctures the fabric. The dual-head motor 65 is started, which drives the two screws 64 to rotate. The two screws 64 drive the mating block 63 to move. The mating block 63 drives the two connecting rods 62 to rotate. The two connecting rods 62 drive the sliding block 61 to move closer to the mating roller 54. The conveyor roller 52 on the sliding frame moves closer to the mating roller 54. The needles 53 on the conveyor belt 51 are inserted into the mating belt 55. Then the tensioning motor 334 is started, which drives the bidirectional screw 333 to rotate. The bidirectional screw 333 moves the two tensioning frames 331 away from each other, and the fabric is in a taut state in the width direction.

[0046] Heating rod 211 is used to increase the temperature inside the drying chamber 1. Swinging component 34 drives the feeding frame 31 to swing. Swinging motor 342 drives incomplete gear 341 to rotate. Incomplete gear 341 meshes with the locking teeth 346 inside the swinging frame 343. The swinging frame 343 moves back and forth, driving rack 344 to move. Rack 344 drives swinging gear 345 to swing. Swinging gear 345 drives feeding frame 31 to swing back and forth. The swinging of feeding frame 31 will cause the fabric to swing. The taut fabric acts as a fan inside the drying chamber 1, making the air inside the drying chamber 1 flow quickly and improving the heat transfer to the fabric.

[0047] During the fabric swinging process, the fabric will pull the fabric at the feed inlet 11. At this time, the fabric coming out of the feed inlet 11 will enter the drying chamber 1 through the pull. During the swinging process, the distance between the feeding frame 31 and the feed inlet 11 changes, causing the material in the fabric drying chamber to be over-rushed. The excess fabric can be wound up by the auxiliary part 4, and the storage part is the fabric that has not yet entered the clamping part 332.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
