Description

Technical Field

[0001] The present invention belongs to the technical field of textile processing, and particularly relates to a continuous fabric spraying and dyeing device and method. Background Art

[0002] With the development of the textile field and people's personalized requirements, more diverse color and pattern design and processing are currently required during fabric processing. Due to equipment molds and processing time, conventional dipping or roller dyeing is often limited by its high cost and long processing time. Therefore, in order to meet such requirements, spraying and dyeing has currently become one of the main means to meet people's diverse needs and small-batch processing.

[0003] Currently, during spraying and dyeing processing, different designs and clothing requirements often need to be sprayed and dyed separately, that is, a single piece of fabric needs to be processed. At this time, processes such as feeding the fabric, waiting for spraying and dyeing, and finally discharging the fabric are required. However, such a processing method has low efficiency and long waiting time, and it is difficult to meet the needs of continuous processing. Moreover, due to the uncertain factors during spraying and dyeing and in the processing environment, the fabric is easily offset due to interference, resulting in pollution of the spraying and dyeing processing area. At the same time, since the length and width dimensions of different fabrics are different, general positioning devices are difficult to adjust and fix, which further leads to inconvenient processing. Larger fabrics often need to be prepared, which further increases the waste of fabrics. On the one hand, it causes waste of resources, and on the other hand, it increases production costs. Summary of the Invention

[0012] The regulator includes an extension clamp, a second motor, and a bidirectional screw. The extension clamp is connected to the middle of the second clamping plate. The second motor is embedded in the extension clamp. The bidirectional screw rotatably penetrates through the extension clamp and is in transmission connection with the second motor. The thread segments on both sides of the bidirectional screw have opposite helix directions. The number of the main clamps is two, and they are respectively connected to the thread segments on both sides of the bidirectional screw.

[0013] The main clamp includes a multi-stage elastic telescopic plate and an electromagnet. The multi-stage elastic telescopic plate is connected to the corresponding thread segment of the bidirectional screw. The multi-stage elastic telescopic plate is in a state of actively extending in the static state. The electromagnet is arranged on the side of the multi-stage elastic telescopic plate close to the bidirectional screw.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] Embodiment 1: As Figures 1-4 shown, a continuous fabric spraying and dyeing device includes a frame 1, a spraying and dyeing mechanism 11 and a control panel. A sprocket drive group is provided in the middle of the frame 1. The chain in the sprocket drive group is an accessory chain 32. A number of fixing mechanisms matching the spraying and dyeing mechanism 11 are equidistantly provided on the accessory chain 32;

[0027] The fixing mechanism includes a carrier plate 2, end rods 21, a first clamping assembly, a second clamping assembly and a side fixing assembly. The number of end rods 21 is two and they are respectively arranged at the left and right ends of the carrier plate 2. The first clamping assembly is arranged on one side of the upper end of the carrier plate 2. The second clamping assembly is slidably connected to the side of the carrier plate 2 and matches the length direction of the carrier plate 2. A number of through slots 22 are evenly and equidistantly formed in the carrier plate 2 along its own length direction. The side fixing assembly is arranged on the carrier plate 2 and corresponds to and matches a number of through slots 22.

[0028] During the spraying and dyeing process, through the setting of the sprocket drive group on the frame 1, a number of fixing mechanisms can be formed into a state of circular motion. A corresponding feeding area is set on one side of the frame 1. At this time, the staff can place the fabric to be sprayed and dyed on the carrier plate 2 at the corresponding position. The control panel intermittently opens and closes the sprocket drive group to meet the spraying and dyeing process at the loading and unloading and the spraying and dyeing mechanism 11. When placing the fabric, place the fabric from one side of the first clamping assembly to the other side of the carrier plate 2. One end of the fabric corresponds to the first clamping assembly. Pull the fabric to the other end of the carrier plate 2 until it is flat. At this time, directly pull the second clamping assembly and slide it to the position corresponding to the other end of the fabric on the carrier plate 2. Finally, start the first clamping assembly and the second clamping assembly at the same time, and the fabric can be stably clamped on the carrier plate 2 to form a flat state. The sliding connection mode between the second clamping assembly and the carrier plate 2 can adopt an elastic sliding connection mode. The friction force after the second clamping assembly abuts against the carrier plate 2 can ensure the stable position of the second clamping assembly in the clamping state, and at the same time, it is convenient for the subsequent rapid unloading and component reset after the spraying and dyeing process. Positive and negative conductive heads are embedded in the two end rods 21. A conductive groove matching the movement track of the end rods 21 is provided on the frame 1. In this way, even in the moving state, an electric power supply can be formed after the end rods 21 abut against the conductive groove to meet the control of the control panel on the electric control components;

[0029] In this way, compared with the conventional spraying and dyeing process of sheet fabrics, the cooperation of the two clamping assemblies can further improve the stability of the processing state of the fabric, and avoid the displacement caused by the disturbance of the outside world or the dye jet during spraying and dyeing, which affects the staining of the sprayed pattern.

[0030] The number of sprocket drive sets is two and they are respectively arranged on the opposite sides of the frame 1. The sprocket drive set includes a drive wheel 3 and a connecting shaft 31. The drive wheel 3 is rotatably arranged on the frame 1. The connecting shaft 31 connects the drive wheels 3 on the same side of the opposite sides and rotatably penetrates through the side of the frame 1. A first motor drivingly connected to the connecting shaft 31 is arranged on the side of the frame 1. An accessory chain 32 is arranged between the two drive wheels 3 on the same side.

[0031] The first clamping assembly includes a first gantry 4, a first electric control telescopic rod 41 and a first clamping plate 42. The first gantry 4 is fixedly connected to the upper end of the carrier plate 2. The first electric control telescopic rod 41 is arranged at the upper end of the first gantry 4. The first clamping plate 42 is located inside the opening of the first gantry 4 and is connected to the output shaft of the first electric control telescopic rod 41.

[0032] The second clamping assembly includes a second gantry 5, a second electric control telescopic rod 51 and a second clamping plate 52. The second gantry 5 is slidably connected to the side of the carrier plate 2 and spans the width of the carrier plate 2. The second electric control telescopic rod 51 is arranged at the upper end of the second gantry 5. The second clamping plate 52 is located inside the opening of the second gantry 5 and is connected to the output shaft of the second electric control telescopic rod 51.

[0033] When clamping the fabric, first ensure that the fabric is basically flat under traction on the carrier plate 2. Then, pull the second gantry 5 in the second clamping assembly corresponding to the end of the fabric. Then, clamping and fixing can be carried out through the control panel on the side of the frame 1. At this time, the first electric control telescopic rod 41 and the second electric control telescopic rod 51 are started synchronously. Furthermore, the first clamping plate 42 and the second clamping plate 52 cooperate with the carrier plate 2 to fixedly clamp both ends of the fabric to meet the fabric stability requirement during the processing of the spraying and dyeing mechanism 11.

[0034] After the processing is completed, the first electric control telescopic rod 41 and the second electric control telescopic rod 51 can be reset through methods such as a position sensor and manual control in the blanking area, thereby canceling the limit fixation. At the same time, the second clamping assembly is reset to meet subsequent blanking and cyclic processing.

[0035] Embodiment 2: As Figures 2-4 shown, in the structure of Embodiment 1, the side fixing assembly includes a regulator, a main clamp and a slave clamp. The regulator is connected to the second clamping plate 52 and is located between the first clamping assembly and the second clamping assembly. The main clamp is connected to the regulator. The carrier plate 2 is also provided with an installation cavity adjacent to the through groove 22. The slave clamp is arranged in the installation cavity and is matched with the main clamp.

[0036] The regulator includes an extension clamp 6, a second motor and a bidirectional screw 61. The extension clamp 6 is connected to the middle of the second clamping plate 52. The second motor is embedded in the extension clamp 6. The bidirectional screw 61 rotatably penetrates through the extension clamp 6 and is drivingly connected to the second motor. The thread segments on both sides of the bidirectional screw 61 have opposite helix directions. The number of main clamps is two and they are respectively connected to the thread segments on both sides of the bidirectional screw 61.

[0037] The main clamp includes a multi-stage elastic telescopic plate 7 and an electromagnet 71. The multi-stage elastic telescopic plate 7 is connected to the corresponding threaded section of the bidirectional screw 61. The multi-stage elastic telescopic plate 7 is in a state of actively protruding in the static state. The electromagnet 71 is arranged on one side of the multi-stage elastic telescopic plate 7 close to the bidirectional screw 61.

[0038] The sub-clamp includes an adsorption strip 8, a sliding strip 81 and a spring 82. The installation cavity includes a transverse groove 83 and a vertical groove 84 that communicate with each other. The transverse groove 83 is opened between two adjacent through grooves 22 on the carrier plate 2 and communicates with them. The vertical groove 84 is opened on the upper and lower sides of the transverse groove 83 on the carrier plate 2 and has a T-shaped structure in the vertical section. The adsorption strip 8 slides left and right in the transverse groove 83. The number of sliding strips 81 is two and they are respectively arranged at the upper and lower ends of the adsorption strip 8. The number of springs 82 is several and they are arranged between the sliding strip 81 and the inner wall of the vertical groove 84. Springs 82 are arranged at both the left and right ends of the sliding strip 81. The adsorption strip 8 is located in the middle of the transverse groove 83 in the static state.

[0039] Further, due to the air disturbance during the spraying of the dye, to prevent the fabric from swinging or shifting due to the air flow disturbance in the side area of the fabric, before the second clamping component clamps the fabric, a camera is also provided on the second gantry 5 to detect the edge position of the fabric on the carrier plate 2. At this time, according to the edge position of the fabric, the second motor starts to control the bidirectional screw 61 to drive the extension clamp 6 to move, so that the main clamp connected to the extension clamp 6 corresponds to the position of the through groove 22 closest to the edge of the fabric. In this way, when the second clamping plate 52 moves down, it will synchronously drive the multi-stage elastic telescopic plate 7 to move down, so as to embed the edge of the fabric into the adjacent through groove 22. With the attraction effect of the electromagnet 71 arranged on the multi-stage elastic telescopic plate 7, the adsorption strip 8 in the installation cavity will be attracted. Since the adsorption strip 8 can slide left and right in the transverse groove 83 and is restricted to the middle by the connection of the sliding strip 81 and the spring 82, the objects attracted are the adsorption strips 8 on both sides adjacent to the multi-stage elastic telescopic plate 7. In this way, the fabric can be effectively clamped and a certain traction effect can be achieved during the downward process, making the fabric flatter and more conducive to the spraying and dyeing process;

[0040] In order to reduce the tediousness of centering and aligning the fabric in the early stage, the number of regulators can also be set to two independent ones, that is, the second motor independently controls the corresponding bidirectional screw 61. At this time, the bidirectional screw 61 is an ordinary screw and has only one threaded section. In this way, the tediousness and difficulty of manual alignment in the early stage can be further reduced through independent control, and the processing efficiency and the accuracy of subsequent fixation can be improved indirectly;

[0041] The multi-stage elastic telescopic plate 7 is composed of a plurality of hollow rectangular sleeves that are sleeved with each other and have gradually decreasing inner diameters, and in the initial state, it is pushed by a spring 82 or other elastic components such as elastic sheets to keep it in an outwardly extended state. Since the extending direction of the multi-stage elastic telescopic plate 7 is perpendicular to the moving direction of the second clamping plate 52, it can not only match the clamping of fabrics of different lengths, but also not affect the movement of the second clamping plate 52, and the subsequent reset is more convenient and fast.

[0042] Embodiment 3: A further improvement based on Embodiment 2. A rectangular electromagnet 71 is provided on the lower side of each telescopic section of the multi-stage telescopic plate. The adsorption strip 8 is divided into multiple sections and each section corresponds to at least one spring 82. When actually adsorbing and clamping the side of the fabric, after each section of the multi-stage telescopic plate extends, due to the certain distance difference between each section of the multi-stage telescopic plate, it will be difficult for the fabric to be firmly adsorbed by the multi-stage telescopic plate and the adsorption strip 8. Therefore, after the adsorption strip 8 is cut into multiple sections and cooperates with a single telescopic section on the multi-stage telescopic plate, it can play an independent role in adsorbing, abutting and clamping, and then play a more stable and firm clamping and traction effect, which better meets the processing requirements.

[0043] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
