Detailed implementation mode

[0028] The present invention will be further described in detail below with reference to the accompanying drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper", "lower", "bottom surface" and "top surface" used in the following description refer to the directions in the accompanying drawings, and the terms "inner" and "outer" refer to the directions towards or away from the geometric center of a specific component respectively.

[0029] The present invention discloses a spraying and dyeing device for printing and dyeing processing, as Figure 1 and Figure 2 shown, which includes a dye tank 1, an unwinding roller 2, a winding roller 3, a dryer 7 and a pair of spraying and dyeing mechanisms 5. The top surface of the dye tank 1 is fixedly connected with a housing 4. A feed inlet 41 is arranged at a position near the bottom end on one outer wall of the housing 4, and a discharge outlet 42 is arranged at a position near the top end on the outer wall of the housing 4 away from the feed inlet 41. A first round roller 43 close to the feed inlet 41 is rotatably connected to the inner wall near the bottom end of the housing 4, and a second round roller 44 close to the discharge outlet 42 is rotatably connected to the inner wall near the top end of the housing 4; The unwinding roller 2 is horizontally and rotatably arranged outside the housing 4 on the side where the feed inlet 41 is located through a first support frame. The winding roller 3 is horizontally arranged outside the housing 4 on the side where the discharge outlet 42 is located through a second support frame. A first motor 31 coaxially and fixedly connected to one end of the winding roller 3 is installed on the outer wall of the second support frame. The dryer 7 is arranged outside the housing 4 on the side close to the winding roller 3. The dryer 7 is located between the housing 4 and the winding roller 3. A drying chamber is arranged in the dryer 7, and the fabric can be dried in the drying chamber. A pair of spraying and dyeing mechanisms 5 are arranged inside the housing 4 and are respectively located outside both sides of the fabric. The spraying and dyeing mechanism 5 can spray the dye in the dye tank 1 onto the fabric.

[0030] The fabric on the unwinding roller 2 is fed into the casing 4 through the feed inlet 41, bypasses the bottom end of the first round roller 43 and the top end of the second round roller 44, and then is sent out through the discharge outlet 42. Then, the output end of the fabric is passed through the drying chamber of the dryer 7 and wound around the winding roller 3. When the first motor 31 is started to drive the winding roller 3 to rotate, the fabric wound on the unwinding roller 2 is unwound and conveyed. During the fabric conveying process, the spraying and dyeing mechanism 5 dyes the fabric. The dyed fabric is dried after passing through the drying chamber and is finally wound on the winding roller 3, realizing the automatic spraying and dyeing of the fabric.

[0031] As Figure 1 、 Figure 2 and Figure 3 shown, the spraying and dyeing mechanism 5 includes a spraying pipe 51 and a pump body 52. The spraying pipe 51 is horizontally fixed on the inner wall of the casing 4. A plurality of nozzles 511 communicating with the spraying pipe 51 are fixed on the outer wall of the spraying pipe 51. The plurality of nozzles 511 are evenly distributed along the axial direction of the spraying pipe 51 and horizontally point to the fabric bypassing between the first round roller 43 and the second round roller 44. The pump body 52 is installed on the outer wall of the casing 4. The input end of the pump body 52 is fixed with a feed pipe 521. The other end of the feed pipe 521 is fixed on the outer wall of the dye tank 1 and communicates with the dye tank 1. The output end of the pump body 52 is fixed with a discharge pipe 522. The other end of the discharge pipe 522 is fixed at the end of the spraying pipe 51 and communicates with the spraying pipe 51.

[0032] During the fabric conveying process, the pump body 52 can be started to extract the dye from the dye tank 1. The dye is conveyed to the spraying pipe 51 through the feed pipe 521 and the discharge pipe 522 and sprayed out through the nozzles 511, so as to spray the dye to automatically dye the conveyed fabric.

[0033] As Figure 1 、 Figure 2 and Figure 3 shown, a pair of baffles 61 are vertically arranged in the casing 4 to block the outside of the side where the nozzles 511 point to the fabric. Cylinders 6 are vertically arranged on the top surface of the dye tank 1 and the inner top wall of the casing 4. The output ends of the two cylinders 6 are respectively fixed to the outer walls of the two baffles 61. The cylinders 6 can drive the baffles 61 to move without blocking the nozzles 511. A pressure sensor 512 for detecting the internal pressure of the spraying pipe 51 is arranged on the spraying pipe 51. A controller 45 is arranged on the outer wall of the casing 4. The input end of the controller 45 is electrically connected to the pressure sensor 512. The output end of the controller 45 is electrically connected to the cylinders 6 and the first motor 31. The controller 45 controls the operation of the cylinders 6 and the first motor 31.

[0034] When the pump body 52 transports the dye to the spray pipe 51, the pressure sensor 512 detects the pressure in the spray pipe 51. When the pressure sensor 512 detects that the air in the spray pipe 51 is not exhausted and the pressure is not constant, the dye ejected from the nozzle 511 will be blocked by the baffle 61, the first motor 31 will not start, and the fabric will not be dyed. When the pressure sensor 512 detects that the pressure reaches a constant value, the controller 45 will control the cylinder 6 and the first motor 31 to work. The cylinder 6 drives the baffle 61 to move downward and no longer block the nozzle 511. The first motor 31 drives the winding roller 3 to rotate to wind the fabric, promoting the feeding and conveying of the fabric, so as to achieve uniform spraying and dyeing of the fabric.

[0035] As Figure 2 and Figure 3 As shown, a plurality of diversion grooves 611 arranged in the vertical direction are formed on the side wall of the baffle 61 close to the nozzle 511. The plurality of diversion grooves 611 are evenly spaced along the length direction of the baffle 61. A plurality of vibration motors 62 capable of vibrating the baffle 61 are installed on the side wall of the baffle 61 away from the diversion grooves 611. A material dropping port 11 communicating with the dye tank 1 is formed on the top wall of the dye tank 1. A pair of diversion plates are fixedly connected to the inner wall of the machine shell 4 and are respectively located at the bottoms of the two baffles 61. The diversion plates are bent and are arranged obliquely downward towards the top of the material dropping port 11. The diversion plates can guide the dye falling on them to the material dropping port 11.

[0036] When there is a lot of dye adhered to the outer wall of the baffle 61, the vibration motor 62 can be started to drive the baffle 61 to vibrate, so that the dye slides down along the diversion grooves 611 to the diversion plates, and the dye falling on them passes through the material dropping port 11 and falls back into the dye tank 1 under the guiding action of the diversion plates, so as to realize the recycling and reuse of the dye.

[0037] As Figure 1 and Figure 4 As shown, a pair of limiting rollers 74 are horizontally rotatably connected to the inner walls near both ends of the drying chamber. The two limiting rollers 74 at the same end are arranged at intervals in the vertical direction and cooperate to form a clearance channel through which the fabric can pass. A pair of blowing pipes 71 are arranged on the inner wall at the middle position of the drying chamber. The pair of blowing pipes 71 are arranged at intervals in the vertical direction. A plurality of air nozzles 711 communicating with the blowing pipes 71 are arranged on the outer walls of the two blowing pipes 71. The plurality of air nozzles 711 are evenly distributed on the outer peripheral surface of the blowing pipes 71. A hot air blower 72 is installed on the top surface of the dryer 7. The input end of the hot air blower 72 is fixedly connected with an air inlet pipe 721 communicating with the external environment. The output end of the hot air blower 72 is fixedly connected with an air outlet pipe 722. The air outlet pipe 722 is a three-way pipe. The end portions of the air outlet pipe 722 far from the hot air blower 72 extend into the two blowing pipes 71 respectively. The air outlet pipe 722 is coaxially rotatably matched with the blowing pipes 71; A plurality of tension rollers are slidably mounted on the inner wall of the drying chamber in the vertical direction and are respectively located on the upper and lower sides of the fabric. The tension rollers are coaxial with the blowing pipes 71. The plurality of tension rollers are evenly spaced and staggered in the fabric conveying direction. The tension rollers located on the upper and lower sides of the fabric can squeeze the fabric to cause the fabric to concave downward and convex upward. This technical means is an existing technology and will not be elaborated here, nor is it shown in the figure.

[0038] The fabric fed into the drying chamber passes through the gap channel between the two pairs of limiting rollers 74 and between the two blowing pipes 71. During the process of fabric conveying and dyeing, the hot air blower 72 is started to convey hot air into the two blowing pipes 71, and the hot air is blown out through the air nozzles 711 to perform double-sided hot air drying on the fabric fed through the drying chamber, so as to wind the fabric. When drying fabrics of different materials or changing the winding speed of the equipment, the required drying time of the fabric is also different. When it is necessary to change the drying time of the fabric in the drying chamber, the fabric can be squeezed by a plurality of tension rollers arranged in the drying chamber to cause the fabric to concave downward and convex upward in a curved shape, so as to change the running path of the fabric in the drying chamber, thereby adjusting the drying time of the fabric to fully dry the fabric.

[0039] As Figure 1 and Figure 5 shown, the blowing pipes 71 are coaxial with the winding roller 3. On the outer walls of one ends of the two blowing pipes 71, straight gears 73 are coaxially fixed. The two straight gears 73 mesh with each other. On the outer wall of the end of the winding roller 3 away from the first motor 31, a first transmission assembly 32 is provided to enable the winding roller 3 to drive any one of the blowing pipes 71 to rotate. The first transmission assembly 32 includes a first pulley 321, a second pulley 322 and a first belt 323. The first pulley 321 is coaxially fixed on the outer wall of the end of the winding roller 3 away from the first motor 31. The second pulley 322 is coaxially fixed on the outer wall of the end of the blowing pipe 71 at a lower position. The first belt 323 is tensioned and sleeved outside the first pulley 321 and the second pulley 322. The first belt 323 links the first pulley 321 and the second pulley 322.

[0040] Under the cooperative work of the first pulley 321, the second pulley 322 and the first belt 323, during the rotation of the winding roller 3, it will drive one of the blowing pipes 71 to rotate. Then, through the meshing cooperation of the two straight gears 73, both of the blowing pipes 71 rotate. By the rotational movement of the blowing pipes 71, the spraying area on the fabric is increased, and the drying efficiency of the fabric is improved.

[0041] As Figure 5 and Figure 6As shown, a stirring shaft 12 coaxial with the blowing pipe 71 is rotatably connected to the inner wall of the dye box 1, a pair of stirring plates 13 are fixedly connected to the outer wall of the stirring shaft 12, and a second transmission component 14 located outside the dye box 1 is arranged on the outer wall of one end of the stirring shaft 12. The second transmission component 14 can make the blowing pipe 71 drive the stirring shaft 12 to rotate. The second transmission component 14 includes a third pulley 141, a fourth pulley 142 and a second belt 143. The third pulley 141 is coaxially fixed to the outer wall of the end of the blowing pipe 71 at a lower position, and the fourth pulley 142 is coaxially fixed to the outer wall of the end of the stirring shaft 12 extending outside the dye box 1. The second belt 143 is tensioned and sleeved on the outside of the third pulley 141 and the fourth pulley 142, and the second belt 143 makes the third pulley 141 and the fourth pulley 142 linked.

[0042] With the cooperation of the third pulley 141, the fourth pulley 142 and the second belt 143, the blowing pipe 71 will drive the stirring shaft 12 to rotate during the rotation process, prompting the stirring plate 13 to stir the dye, thereby reducing the possibility of sedimentation of the auxiliary agent in the dye and improving the quality of spray dyeing.

[0043] Printing and dyeing spray production system, such as Figure 7 and Figure 8 As shown, it includes a roller assembly 8 and a printing and dyeing spraying device. The roller assembly 8 is arranged between the casing 4 and the dryer 7, and is used to extrude the conveyed cloth. The roller assembly 8 includes a pair of squeezing rollers 81 and a second motor 82. The pair of squeezing rollers 81 are horizontally rotatably arranged between the casing 4 and the dryer 7 through a third support frame. The two squeezing rollers 81 are coaxial with the unwinding roller 2 and are arranged at intervals in the vertical direction to cooperate to form a clearance channel for the cloth to pass through. The second motor 82 is installed on the outer wall of the third support frame, and the output end of the second motor 82 is coaxially fixed to one end of the squeezing roller 81 at a higher position.

[0044] The cloth sent out from the discharge port 42 passes through the yield channel between the two squeezing rollers 81. When the cloth is transported into the dryer 7, the second motor 82 is started to drive the squeezing roller 81 located above the cloth to squeeze the dyed cloth to remove excess dye on the cloth so that the cloth can be quickly dried after entering the dryer 7.

[0045] Working principle: Draw out the fabric wound around the unwinding roller 2, feed the output end of the fabric into the machine housing 4 through the feed port 41, let the fabric pass around the first round roller 43 and the second round roller 44 and then send it out through the discharge port 42, and then pass the output end of the fabric through the drying chamber of the dryer 7 and wind it around the winding roller 3; When spraying and dyeing the fabric, start the pump body 52 to transport the dye in the dye tank 1 to the spraying pipe 51 and then spray it out through the spray head 511. When the pressure sensor 512 detects that the air in the spraying pipe 51 is not exhausted and the pressure is not constant, the dye sprayed out by the spray head 511 will be blocked by the baffle 61, the first motor 31 will not start, and the fabric will not be sprayed and dyed. When the pressure sensor 512 detects that the pressure in the spraying pipe 51 reaches a constant value, the controller 45 will control the cylinder 6 and the first motor 31 to work. The cylinder 6 drives the baffle 61 to move down and no longer block the spray head 511. The first motor 31 drives the winding roller 3 to rotate to wind the fabric, promoting the feeding and conveying of the fabric, so as to achieve uniform spraying and dyeing of the fabric; During the process of the winding roller 3 rotating to wind the fabric, the dyed fabric will be conveyed into the drying chamber. Start the hot air blower 72 to send hot air into the two blowing pipes 71, and blow out the hot air through the air nozzles 711 to perform double-sided hot air drying on the fabric fed through the drying chamber. Under the meshing cooperation of the first transmission component 32 and the two spur gears 73, the winding roller 3 will drive the two blowing pipes 71 to rotate during the rotation process, and the rotation action of the blowing pipe 71 increases the blown area on the fabric and improves the fabric drying efficiency; Under the cooperative work of the second transmission component 14, the blowing pipe 71 will drive the stirring shaft 12 to rotate during the rotation process, prompting the stirring plate 13 to stir the dye, reducing the possibility of sedimentation of the solute in the dye, and thus improving the fabric spraying and dyeing quality.

[0046] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
