[0022] The auxiliary component comprises a motor 23 fixedly installed on the inner wall of the spraying box 1, the output shaft of the motor 23 is fixedly connected with a rotating shaft one 24, the surfaces of the two pressing rollers 15 are fixedly connected with rotating shafts two 27, a belt pulley transmission mechanism 28 is arranged between the rotating shaft one 24 and the rotating shafts two 27, and a hinged plate 29 is hingedly connected between the rotating shaft one 24 and the rotating shafts two 27.

[0023] The spraying component comprises a gear one 34 fixedly connected with the surface of the rotating shaft one 24, the inner wall of the spraying box 1 is fixedly connected with two symmetrical rotating shafts three 25, the surfaces of the two rotating shafts three 25 are fixedly connected with gear twos 26 engaged with the gear one 34, the surfaces of the two gear twos 26 are fixedly connected with moving columns 35, the outer surfaces of the two moving columns 35 are slidingly connected with moving frames 21, the inner wall of the spraying box 1 is fixedly installed with a limiting rod 22, and the limiting rod 22 penetrates through one moving frame 21 and is slidingly connected therewith.

[0024] The upper surface of the spraying box 1 is provided with a liquid storage tank 5, the surface of the liquid storage tank 5 is fixedly connected with two liquid outlet pipes 9, the surface of the liquid storage tank 5 is fixedly connected with two symmetrical communication pipes one, the end portions of the two communication pipes one are fixedly connected with fixed frames 39, and two groups of fixed nozzles 38 are arranged below the two fixed frames 39. The surfaces of the two moving frames 21 are fixedly connected with fixed plates 20, the lower portions of the two fixed plates 20 are fixedly installed with liquid storage frames 19, the upper surfaces of the two liquid storage frames 19 are fixedly connected with communication pipes two, the two communication pipes two and the two liquid outlet pipes 9 are fixedly connected with two liquid conveying hoses 11, respectively, and a plurality of moving nozzles 18 are uniformly arranged on the lower surfaces of the two liquid storage frames 19.

[0025] The surfaces of the cloth unwinding roller 3 and the winding roller 4 are provided with driving motors 8, and the surface of the spraying box 1 is provided with a control panel 2.

[0026] The surface of the liquid storage tank 5 is fixedly connected with a liquid adding pipe 6, and the surface of the liquid adding pipe 6 is provided with a sealing plug.

[0027] More specifically, in the embodiment: As shown in Figure 1 and Figure 2 , the leather 7 to be sprayed is unwound from the cloth unwinding roller 3, sequentially passes through the pressing roller 15 and the driven roller 17, and is finally wound on the winding roller 4.

[0028] As shown in Figure 3 and Figure 4As shown, the motor 23 is started, driving the rotation of the shaft 24, with the rotation of the shaft 24, under the action of the two belt pulley transmission mechanisms 28, then the two shafts 27 will drive the two compression rollers 15 to rotate synchronously, and because the shaft 27 and the shaft 24 are hinged through the hinge plate 29, the two compression rollers 15 can rotate around the shaft 27 and offset around the shaft 24, the spring 31 is in a compressed state, under the action of the elastic potential energy of the spring 31, the two compression rollers 15 will tightly press the leather 7 below, so as to ensure that the leather 7 between the two compression rollers 15 is taut; In the process of leather spraying, if the leather surface cannot be taut, there will be wrinkles, and the spraying liquid will concentrate in the low-lying part of the wrinkles, resulting in over-thick spraying in this area, while the protruding part of the wrinkles may be insufficiently sprayed, which seriously affects the uniformity and overall quality of the spraying. By tightening the leather below the moving nozzle 18 with the two compression rollers 15, wrinkles can be effectively eliminated during spraying, ensuring that the leather surface is smooth and flat, creating good conditions for uniform spraying, so that the spraying liquid can be evenly attached to the leather surface, improving the spraying effect of the leather 7 and improving the appearance of the finished leather after spraying.

[0029] At the same time, as shown Figure 2 The spraying liquid in the liquid storage tank 5 will enter the liquid storage frame 19 through the liquid outlet pipe 9, the liquid conveying hose 11 and the communication pipe 2, and finally be sprayed uniformly from the multiple moving nozzles 18 below the liquid storage frame 19; With the start of the motor 23, the rotation of the shaft 24 will also drive the rotation of the gear 34, under the meshing action of the gear 34 and the two gears 26, the rotation of the gear 34 will drive the synchronous rotation of the two gears 26, with the rotation of the gear 26, the moving column 35 will move in a circular motion, because the two moving frames 21 are connected to the outer surface of the two moving columns 35, one is limited by the limiting rod 22, and the other is limited by the piston rod 33, so with the circular motion of the moving column 35, the two moving frames 21 will move back and forth in the horizontal direction, with the reciprocating movement of the moving frame 21, under the connection action of the fixed plate 20, the liquid storage frame 19 will drive the moving nozzle 18 to move from the middle position to both sides above the leather 7 while spraying the spraying liquid, and move closer to the two groups of fixed nozzles 39, so that the moving nozzle 18 forms a more dense and detailed spraying area when it is close to the fixed nozzle 39, making the coating of the spraying liquid on the leather surface more delicate and uniform. Similarly, when the two groups of moving nozzles 18 move to the closest position, the two groups of moving nozzles 18 in this state can also form a more dense and detailed spraying area. This moving spraying method can ensure that the spraying liquid is more delicate and uniform on the surface of the leather 7, avoiding the problem of insufficient spraying in local areas, and improving the quality of the produced leather products.

[0030] Example 2, based on the above examples, Furthermore, the drying component in Embodiment 1 is disclosed. The drying component includes a piston cylinder 12 fixedly installed on the inner wall of the spray box 1. A piston plate is slidably connected to the inner wall of the piston cylinder 12. A piston rod 33 is fixedly connected to the surface of the piston plate. The end of the piston rod 33 extending out of the piston cylinder 12 is fixedly connected to another movable frame 21.

[0031] The surface of the piston cylinder 12 is fixedly connected to the air inlet pipe 10 and the air outlet pipe 14. The surfaces of the air inlet pipe 10 and the air outlet pipe 14 are both equipped with one-way valves. The surface of the spray box 1 is fixedly connected to the mounting plate 2 36. The surface of the mounting plate 2 36 is fixedly installed with the drying pipe 13. The end of the air outlet pipe 14 is fixedly connected to the drying pipe 13. The surface of the drying pipe 13 is evenly provided with multiple air outlets 37.

[0032] More specifically, in this embodiment: like Figure 5 As shown, when the motor 23 is turned on, the rotating shaft 24 rotates, causing the moving frame 21 to move back and forth in the horizontal direction. At the same time, the movement of the moving frame 21 also causes the piston rod 33 to drive the piston plate to move back and forth in the piston cylinder 12. It is a mature existing technology to set a heating component above the spray box 1 and connect it to the air inlet pipe 10 for air heating, so it will not be described in detail here. Under the action of piston adsorption in the piston cylinder 12, hot air can be drawn in through the air inlet pipe 10 and input into the drying pipe 13 through the air outlet pipe 14. The hot air in the drying pipe 13 will be evenly sprayed out through multiple air outlets 37 to the surface of the leather 7 after spraying, so that the leather 7 can be dried before being rolled up, so that the spray liquid on the surface of the leather 7 can be quickly cured, which can prevent the spray liquid from flowing or migrating on the surface of the leather, ensuring the clarity and stability of the spray pattern on the surface of the leather, and improving the quality of the produced leather products.

[0033] Working principle: a kind of leather production intelligent uniform spraying device, when using, open the drive motor of the surface of the cloth releasing roller 3 and the winding roller 4, the leather 7 to be sprayed is released from the cloth releasing roller 3, and passes through the compression roller 15 and the driven roller 17 in turn, while the motor 23 is started, the rotating shaft one 24 is driven to rotate, under the action of the two belt pulley transmission mechanism 28 and the hinged plate 29, the two compression rollers 15 rotate around the rotating shaft two 27 and offset downward around the rotating shaft one 24, because the spring 31 is in a compressed state under the action of the elastic potential energy, the two compression rollers 15 will tightly press the leather 7 below, so that the leather 7 between the two compression rollers 15 is taut, which can effectively eliminate the wrinkles on the surface of the leather 7 during spraying, ensure the smoothness of the leather surface, and make the spraying liquid adhere uniformly on the surface of the leather, improve the spraying effect of the leather 7 and the appearance of the finished leather after spraying.

[0034] With the opening of the motor 23, the rotation of the rotating shaft one 24 also drives the gear one 34 to rotate, under the meshing action of the gear one 34 and the two gear two 26, the moving column 35 moves in a circular motion on the surface of the gear two 26, so that the two moving frames 21 move back and forth in the horizontal direction, with the reciprocating movement of the moving frame 21, under the connection action of the fixed plate 20, the liquid storage frame 19 drives the moving nozzle 18 to move from the middle position to both sides above the leather 7 while spraying the spraying liquid, so as to move closer to the two groups of fixed nozzles 39, so that the moving nozzle 18 forms a more dense and detailed spraying area with the fixed nozzle 39 when it is close to the fixed nozzle 39, so that the coating layer formed by the spraying liquid on the surface of the leather is more delicate and uniform; compared with the traditional static spraying moving nozzle, the reciprocating spraying of the moving nozzle 18 can ensure that the spraying liquid covers the surface of the leather 7 uniformly and delicately, avoid the problem of insufficient spraying in local area, and improve the quality of the produced leather product.

[0035] It is worth noting that, while the moving frame 21 moves back and forth in the horizontal direction with the opening of the motor 23, the piston rod 33 also drives the piston plate to move back and forth in the piston cylinder 12, a heating assembly is arranged above the spraying box 1 and is connected with the air inlet pipe 10, under the action of the piston suction of the piston cylinder 12, hot air can be sucked into the air inlet pipe 10 and sprayed uniformly to the surface of the leather 7 below through the multiple air outlets 37 on the surface of the drying pipe 13, so as to dry the leather 7 before winding, so that the spraying liquid on the surface of the leather 7 can be quickly solidified, thereby avoiding the flow or migration of the spraying liquid on the surface of the leather, so as to ensure the clarity and stability of the spraying pattern on the surface of the leather, and further improve the quality of the produced leather product.

[0036] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely exemplary of the principles and application of the present application. Numerous modifications and adaptions can be effected without departing from the spirit and scope of the present application, which is not limited to the exact construction and arrangement described.
