Description

Technical Field

[0001] The invention belongs to the technical field of textile processing, and in particular relates to a continuous cloth spray-dyeing device and method. Background Art

[0002] With the development of the textile field and people's personalized requirements, more diversified color and pattern design processing is required in fabric processing. Conventional dip dyeing or drum dyeing is often limited by its high cost and long processing time due to equipment molds and processing time. Therefore, in order to meet such needs, spray dyeing has become one of the main means to meet people's diversified needs and small-scale processing.

[0003] At present, when performing spray-dyeing processing, different designs and clothing requirements often need to be spray-dyed separately, that is, a single piece of cloth needs to be processed, and at this time, the cloth needs to be loaded, waited for spray-dyeing, and finally unloaded. However, this processing method is inefficient and the waiting time is too long, which is difficult to meet the continuous processing needs. In addition, due to the uncertainty factors during spray-dyeing and in the processing environment, the cloth is easily disturbed and offset, resulting in contamination of the spray-dyeing processing area. At the same time, since different cloths have different lengths and widths, general positioning devices are difficult to adjust and fix, which leads to inconvenience in processing. Often, larger cloth is required for preparation, which leads to an increase in waste cloth, which on the one hand causes waste of resources, and on the other hand leads to increased production costs.

DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Example 1: Figure 1-4 As shown, a continuous fabric spray-dyeing device comprises a frame 1, a spray-dyeing mechanism 11 and a control panel. A sprocket transmission group is provided in the middle of the frame 1. The chain in the sprocket transmission group is an accessory chain 32. A plurality of fixing mechanisms matching the spray-dyeing mechanism 11 are equidistantly provided on the accessory chain 32. The fixing mechanism includes a carrier plate 2, an end rod 21, a first clamping assembly, a second clamping assembly and a side fixing assembly. There are two end rods 21 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. The carrier plate 2 has a plurality of through grooves 22 evenly and equidistantly opened along its own length direction. The side fixing assembly is arranged on the carrier plate 2 and corresponds to the plurality of through grooves 22.

[0023] When performing spray-dyeing, by setting the sprocket transmission group on the frame 1, several fixed mechanisms can be put into a state of circular motion, and a corresponding loading area is set on one side of the frame 1. At this time, the staff can place the cloth to be spray-dyeed on the carrier 2 at the corresponding position, wherein the control panel intermittently opens and closes the sprocket transmission group to meet the requirements of loading and unloading and spray-dyeing processing at the spray-dyeing mechanism 11. When placing the cloth, the cloth is placed from one side of the first clamping component to the other side of the carrier 2, wherein one end of the cloth corresponds to the first clamping component, and the cloth is pulled to the other end of the carrier 2 until it is flat, and then the second clamping component is directly pulled and slid to the position on the carrier 2 corresponding to the other end of the cloth, and finally started at the same time. The first clamping assembly and the second clamping assembly can stably clamp the cloth on the carrier plate 2 to form a flat state, wherein the sliding connection between the second clamping assembly and the carrier plate 2 can adopt an elastic sliding connection, and the friction force after the second clamping assembly and the carrier plate 2 are in contact can ensure the stability of the position of the second clamping assembly in the clamping state, and at the same time facilitate the rapid unloading and component reset after the subsequent spray-dyeing process is completed. The two end rods 21 are embedded with positive and negative conductive heads, and the frame 1 is provided with a conductive groove matching the movement trajectory of the end rods 21, so that after the end rods 21 are in contact with the conductive groove, power supply can be formed even in the moving state to meet the control of the control panel on the electric control components; Compared with conventional sheet-like fabric spray-dyeing processing, the cooperation of the two clamping components can further improve the stability of the fabric processing state, and avoid displacement caused by external disturbances or dye jetting during spray-dyeing, which may affect the spray-dyeing pattern.

[0024] There are two sprocket transmission groups and they are respectively arranged on opposite sides of the frame 1. The sprocket transmission group includes a transmission wheel 3 and a connecting shaft 31. The transmission wheel 3 is rotatably arranged on the frame 1. The connecting shaft 31 connects the transmission wheels 3 on the same side of the opposite side and rotates through the side of the frame 1. A first motor is provided on the side of the frame 1 and is transmission-connected to the connecting shaft 31. An accessory chain 32 is arranged between the two transmission wheels 3 on the same side.

[0025] The first clamping assembly includes a first door frame 4, a first electrically-controlled telescopic rod 41 and a first clamping plate 42. The first door frame 4 is fixedly connected to the upper end of the carrier plate 2. The first electrically-controlled telescopic rod 41 is arranged at the upper end of the first door frame 4. The first clamping plate 42 is located in the opening of the first door frame 4 and is connected to the output shaft of the first electrically-controlled telescopic rod 41.

[0026] The second clamping assembly includes a second gantry 5, a second electrically-controlled 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 electrically-controlled telescopic rod 51 is arranged at the upper end of the second gantry 5. The second clamping plate 52 is located in the opening of the second gantry 5 and is connected to the output shaft of the second electrically-controlled telescopic rod 51.

[0027] When clamping the cloth, first ensure that the cloth is pulled basically flat on the carrier plate 2, then pull the second door frame 5 in the second clamping assembly to the end of the cloth, and then clamp and fix it through the control panel on the side of the frame 1. At this time, the first electric telescopic rod 41 and the second electric telescopic rod 51 are started synchronously, and then the first clamping plate 42 and the second clamping plate 52 are used to cooperate with the carrier plate 2 to fix and clamp the two ends of the cloth, so as to meet the stability of the cloth during processing by the spray-dyeing mechanism 11; After the processing is completed, the first electrically-controlled telescopic rod 41 and the second electrically-controlled telescopic rod 51 can be reset by means of position sensors, manual control of the unloading area, etc., thereby canceling the limit fixation and resetting the second clamping assembly to meet the subsequent unloading and cyclic processing.

[0028] Example 2: Figure 2-4 As shown, in the structure of Example 1, the side fixing assembly includes an adjuster, a main clamp and a slave clamp, the adjuster 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 adjuster, and the carrier plate 2 also has an installation cavity adjacent to the through groove 22, and the slave clamp is arranged in the installation cavity and matches with the main clamp.

[0029] The adjuster includes an extension clamp 6, a second motor and a bidirectional screw 61. The extension clamp 6 is connected to the middle part of the second clamp plate 52. The second motor is embedded in the extension clamp 6. The bidirectional screw 61 rotates through the extension clamp 6 and is connected to the second motor. The threaded sections on both sides of the bidirectional screw 61 rotate in opposite directions. There are two main clamps, which are respectively connected to the threaded sections on both sides of the bidirectional screw 61.

[0030] The main clamp includes a multi-stage elastic expansion plate 7 and an electromagnet 71. The multi-stage elastic expansion plate 7 is connected to the corresponding threaded section of the bidirectional screw 61. The multi-stage elastic expansion plate 7 is actively extended in a static state. The electromagnet 71 is arranged on the side of the multi-stage elastic expansion plate 7 close to the bidirectional screw 61.

[0031] The slave clamp includes an adsorption strip 8, a slide bar 81 and a spring 82. The mounting cavity includes a transverse groove 83 and a vertical groove 84 that are interconnected. The transverse groove 83 is opened between two adjacent through grooves 22 on the carrier plate 2 and interconnects 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 vertical section. The adsorption strip 8 is slidable left and right in the transverse groove 83. There are two slide bars 81, which are respectively arranged at the upper and lower ends of the adsorption strip 8. There are several springs 82, which are arranged between the slide bar 81 and the inner wall of the vertical groove 84. Springs 82 are provided at the left and right ends of the slide bar 81. The adsorption strip 8 is located in the middle of the transverse groove 83 in a stationary state.

[0032] Furthermore, since there is air disturbance when the dye is sprayed during spray dyeing, in order to prevent the side area of ​​the cloth from swinging or deflecting due to air disturbance, before the second clamping assembly clamps the cloth, a camera is also provided on the second door frame 5 for detecting the edge position of the cloth on the carrier plate 2. At this time, according to the edge position of the cloth, 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 slot 22 closest to the edge of the cloth, so that when the second clamping plate 52 moves down, it will synchronously drive the multi-stage The elastic expansion plate 7 moves downward, so that the edge of the cloth is embedded in the adjacent through groove 22. With the attraction effect of the electromagnet 71 provided on the multi-stage elastic expansion 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 by the connection center of the slide bar 81 and the spring 82, the adsorption strip 8 on both sides of the multi-stage elastic expansion plate 7 is attracted. In this way, the cloth can be effectively clamped and a certain traction effect is played in the downward process, making the cloth smoother and more conducive to spray dyeing. In order to reduce the complexity of the centering of the cloth in the early stage, the number of regulators can also be set to two independent ones, that is, the second motor controls the corresponding bidirectional screw 61 independently. At this time, the bidirectional screw 61 is a common screw and has only one thread segment. In this way, the complexity and difficulty of the manual positioning in the early stage can be further reduced by independent control, and the processing efficiency and the accuracy of subsequent fixing can be improved in disguise. The multi-stage elastic telescopic plate 7 is composed of a plurality of hollow rectangular sleeves which are mutually nested and whose inner diameters gradually decrease. In the initial state, it is pushed by a spring 82 or other elastic components such as a spring sheet to maintain an outwardly extended state. Since the extension direction of the multi-stage elastic telescopic plate 7 is perpendicular to the movement direction of the second clamping plate 52, it can not only match the clamping of fabrics of different lengths, but also will not affect the movement of the second clamping plate 52, and the subsequent resetting is also more convenient and quick.

[0033] Embodiment 3: A further improvement on the basis of 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, so that when the side of the cloth is actually adsorbed and clamped, after each section of the multi-stage telescopic plate is extended, due to the certain distance difference between each section of the multi-stage telescopic plate, it will make it difficult for the cloth to be firmly adsorbed by the adsorption strip 8 through the multi-stage telescopic plate. Therefore, after the adsorption strip 8 is cut into multiple sections, it can cooperate with the single telescopic section on the multi-stage telescopic plate to play an independent adsorption, abutment and clamping role, thereby achieving a more stable and firm clamping and traction effect, better meeting the processing needs.

[0034] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made 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.
