DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in 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.

[0019] like Figures 1 to 7 As shown, the present invention provides a batik cloth resist slurry scraping device and a process thereof, comprising a bottom mold 100 and a gantry 200, wherein the bottom mold 100 receives the grey cloth and a flower plate 800 covering the grey cloth, and further comprises a sprayer 300 and a heater 400, wherein the sprayer 300 and the heater 400 are both mounted on the sprayer 300, and the heater 400 supplies molten beeswax to the sprayer 300; A linear drive mechanism 500, on which a cantilever 501 is slidably mounted, on which a cylinder 502 is mounted, and an output end of the cylinder 502 is connected to a scraper 504, wherein the lower edge of the scraper 504 is pressed on the grey cloth at an angle of 40-50 degrees to the horizontal; The air pump 700 is mounted on the gantry 200 and its output end is connected to the sprayer 300, and is used to spray the beeswax in the sprayer 300. The air pump 700 is mixed with the molten beeswax and sprays the beeswax at a high speed to improve uniformity.

[0020] Lay the flower board 800 on the grey cloth, and then drive the sprayer 300 to spray the beeswax downwards on the flower board 800. A linear motor is provided at the bottom of the gantry 200 to drive its linear movement, and a lead screw mechanism is provided above the sprayer 300 to cooperate with the linear motor on the gantry 200 to drive the sprayer 300 on a two-dimensional plane to spray the beeswax to cover the entire flower board 800. After the beeswax fills the pattern of the flower board 800 and covers the grey cloth, drive the scraper 504 to scrape off the excess beeswax around the flower board 800 at an angle of 40-50 degrees, and make the beeswax in the pattern fit on the grey cloth. Then tear off the flower board 800.

[0021] like Figure 4 and 5 As shown, the sprayer 300 includes a heating tube 301 and a nozzle 302. The input and output ends of the heating tube 301 are respectively connected to the air pump 700 and the nozzle 302. A heating wire is arranged in the inner cavity of the heating tube 301 to heat the airflow passing therethrough. The nozzle 302 includes a fluid channel 3021 connected to the heater 400 and an air flow channel 3022 connected to the heating tube 301 . The fluid channel 3021 and the air flow channel 3022 are combined and extend downward to the nozzle of the nozzle 302 .

[0022] The heating wire in the heating tube 301 quickly heats the passing airflow to prevent the low-temperature airflow from solidifying the beeswax. At the same time, it can form a gas-liquid mixed state with the molten beeswax, break up the beeswax through the combined pipe, and then spray it out evenly.

[0023] like Figure 5 As shown, a plurality of mixing chambers 3023 are provided on the combined channel of the fluid channel 3021 and the air flow channel 3022 , and the inner diameter of the mixing chamber 3023 is larger than the combined diameter of the fluid channel 3021 and the air flow channel 3022 .

[0024] The airflow can be fully mixed with the beeswax multiple times in the mixing chamber 3023. When the beeswax and airflow mixture is in the merging pipe, it is limited by the inner diameter of the pipe and is in a state of high pressure. When it is in the mixing chamber 3023, the pressure suddenly decreases, and the mixture spreads and fills the cavity, fully mixing the beeswax and the airflow. After multiple cycles, the effect of full mixing is achieved, so that the beeswax can be sprayed out evenly.

[0025] like Figures 4 to 7 As shown, the heater 400 includes a barrel body 401 and a heating wire 402. The barrel body 401 is a sandwich structure and the heating wire 402 is arranged in the sandwich. The heater 400 further includes a screw pump 404, an output pipe 405 and a return pipe 406. The sprayer 300 further includes a return channel 304 connected to the fluid channel 3021. The inner cavity of the barrel 401, the screw pump 404, the output pipe 405, the return pipe 406, the fluid channel 3021 and the return channel 304 together constitute a return channel. The return flow channel is opened by a stop valve.

[0026] The above scheme is a scheme for preventing the beeswax from solidifying in the conduit when the spraying stops. A reflux channel is constructed by means of the screw pump 404, the output pipe 405, the reflux pipe 406, the fluid channel 3021 and the reflux channel 304. When the beeswax stops spraying, the reflux channel is opened and the spraying channel is cut off. The refluxed beeswax continues to be injected back into the heater 400 to continue to be heated at a constant temperature, and the pipeline continues to maintain a flow state until the reflux channel is cut off again and the spraying channel is opened.

[0027] like Figure 4 and Figure 5 As shown, the stop valve includes a valve plate 3033 and a valve ball 3034 respectively arranged in the return channel 304 and the fluid channel 3021, and the valve plate 3033 and the valve ball 3034 are fixedly connected by a connecting rod 3032. The valve plate 3033 and the valve ball 3034 control the return channel 304 and the fluid channel 3021 to be connected; The stop valve further includes a coil 3031 mounted on the spray head 302 for driving the connecting rod 3032 to move.

[0028] The bottom end of the connecting rod 3032 is a permanent magnet, which can be attracted or repelled by the coil 3031 and then drive the valve plate 3033 and the valve ball 3034 to move upward or downward synchronously. When the connecting rod 3032 moves upward, the return channel 304 is cut off, and the fluid channel 3021 is opened. At this time, the beeswax enters the combined channel of the fluid channel 3021 and the air flow channel 3022 and is released. When the connecting rod 3032 moves downward, the return channel 304 is opened, and the fluid channel 3021 is cut off. At this time, the beeswax finally flows back from the return channel 304 and the return pipe 406 to the heater 400 for continued heating. It is used to control the flow direction of the beeswax after spraying and stopping spraying.

[0029] like Figure 6 and Figure 7 As shown, the barrel body 401 further includes a partition 403 for dividing the inner cavity of the barrel body 401 , and the cavity above the partition 403 contains molten beeswax.

[0030] The return pipe 406 extends upward through the partition 403 to the cavity above the partition 403, and guides the beeswax into the cavity to be reheated. The lower cavity can be used to set a heating element, etc.

[0031] like Figure 2 and Figure 3 As shown, the linear drive mechanism 500 also includes a telescopic rod 503 connected to the scraper 504. The telescopic rod 503 and the scraper 504 are connected via an elastic hinge, and the telescopic end of the telescopic rod 503 is fixedly connected to the output end of the cylinder 502 via a crossbeam.

[0032] The above scheme is one of the preferred implementations of the scraper 504. The telescopic rod 503 is connected to the scraper 504 through an elastic hinge. When the cylinder 502 extends downward, the telescopic rod 503 drives the scraper 504 to move downward. The scraper 504 is finally pressed on the flower plate 800 and tilted at an angle. The elastic hinge helps to apply a fixed elastic force after the scraper 504 tilts at a fixed angle, so that the pressure of the scraper 504 pressing on the flower plate 800 can be kept constant during movement. Both ends of the bottom mold 100 are provided with bevels. When the scraper 504 moves downward, it can be located outside the end of the bottom mold 100. After it moves downward to a fixed distance, it is moved by the linear drive mechanism 500. After the scraper 504 contacts the bevel, the contact angle with the flower plate 800 changes to an inclined shape. The bevel avoids the hidden danger of the scraper 504 being damaged by direct contact with the sharp corner; when the scraper 504 finishes scraping in a single direction, the cylinder 502 lifts the scraper 504 to separate it from the flower plate 800 and returns it to its original position, and then repeats the same-direction scraping.

[0033] like Figure 1-Figure 4 As shown, the anti-dyeing slurry scraping device also includes a negative pressure suction cup 602, which is installed on the scraping device through rotating arms 601 arranged on both sides of the bottom mold 100, and the rotating arms 601 are driven to rotate by a driving machine 603 installed on one side of the gantry 200. The negative pressure suction cup 602 is arranged above the flower board 800 to absorb the flower board 800 and tear it off.

[0034] After the excess beeswax on the flower board 800 is scraped off, the driving machine 603 drives the rotating arm 601 to drive the negative pressure suction cup 602 to rotate, so that the negative pressure suction cup 602 is adsorbed on one end of the flower board 800. As the driving machine 603 drives the negative pressure suction cup 602 to rotate in the opposite direction, the negative pressure suction cup 602 lifts the flower board 800 upward from one end, and peels off from one side of the flower board 800. One end of the negative pressure suction cup 602 can be connected to the negative pressure fan through an air pipe, so that the negative pressure hole on the negative pressure suction cup 602 adsorbs the flower plate 800 when it is in contact with the flower plate 800.

[0035] like Figure 1-Figure 3As shown, the base mold 100 includes guide grooves 101 opened on both sides of the top surface of its body, and the guide grooves 101 have a height difference. The base mold 100 also includes a collection box 102 arranged at one end of its body. The collection box 102 is located at the end of the guide groove 101 and is used to receive the beeswax flowing down therefrom.

[0036] After the scraper 504 scrapes off the beeswax on the flower plate 800, the beeswax flows down from both sides or ends. The beeswax on both sides flows through the guide groove 101 and finally enters the collection box 102 for collection. The collection box 102 can be set at both ends of the bottom mold 100, and only one side is set for demonstration in the schematic diagram.

[0037] A batik cloth resist slurry process, wherein the part of the grey cloth to be dyed is leveled and placed in a bottom mold 100, a pattern board 800 is leveled and laid on the grey cloth, a sprayer 300 is controlled to evenly spray molten beeswax on the pattern board 800, and after the beeswax is filled in the lines of the pattern board 800, a scraper 504 is started to scrape the pattern board 800 several times in a row until there is no obvious beeswax outside the lines of the pattern board 800, and the pattern board 800 is uncovered after the beeswax solidifies; Place the grey cloth in the dye vat for dyeing, and then place the dyed cloth in a ventilated environment to dry naturally after completion; Use a knife to scrape off the beeswax on the dyed cloth after it has dried, and clean the remaining beeswax.
