[0027] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0028] Example: Figure 1-4 As shown, the utility model provides a technical solution, a spraying device for PVC coated cloth, comprising a working platform 1, both ends of the working platform 1 are provided with a retracting mechanism 2, a liquid storage tank 3 is fixedly installed on the top of the working platform 1, a water pump 4 is arranged on the top of the liquid storage tank 3, a spraying roller 5 is fixedly connected to the bottom of the water pump 4, the spraying roller 5 is fixedly installed on the top of the working platform 1, and the top of the working platform 1 is at the bottom of the spraying roller 5 and is rotatably connected to a guide roller 6;

[0029] A guide stretching assembly 7 is provided on the top of the working platform 1, and the guide stretching assembly 7 includes a driving motor 701, a bidirectional threaded rod 702, a moving plate 703, a limiting roller 704, a supporting plate 705, a rotating roller 706, a mounting rod 707 and a stretching wheel 708;

[0030] A driving motor 701 is fixedly installed at one end of the working platform 1, and both ends of the working platform 1 are rotatably connected with bidirectional threaded rods 702. The two ends of the two-way threaded rods 702 are connected by a belt connecting mechanism. The output shaft of the driving motor 701 is fixedly connected to the belt connecting mechanism to facilitate synchronous driving of the two moving plates 703 to move. Both ends of the outer sides of the bidirectional threaded rods 702 are connected to the moving plates 703 by threads. A moving groove is opened at the bottom of the working platform 1 corresponding to the moving plate 703. The outer diameter of the bottom of the moving plate 703 is equal to the inner diameter of the moving groove, so as to ensure the stability of the movement of the moving plate 703 , to avoid the problem of shaking when the movable plate 703 moves, a plurality of limiting rollers 704 are evenly arranged inside the movable plate 703, and support plates 705 are installed at both ends of the top surface of the working platform 1 by screws, and rotating rollers 706 are rotatably connected at both ends of the support plates 705, and mounting rods 707 are installed on the top of the two movable plates 703 by screws, and stretching wheels 708 are rotatably connected at both ends of one side of the mounting rod 707, and the stretching wheel 708 is inclined. The stretching wheel 708 is located on the top of a support plate 705, which is convenient for stretching the PVC coated cloth and ensuring the flatness of the PVC coated cloth.

[0031] A leveling and drying assembly 8 is disposed on the top of the other support plate 705, and the leveling and drying assembly 8 includes an electric telescopic column 801, a leveling roller 802, a blowing fan 803, a blowing pipe 804 and a heating wire 805;

[0032] Electric telescopic columns 801 are installed at both ends of the other support plate 705 by screws, and the tops of the two electric telescopic columns 801 are connected by a leveling roller 802. A blowing fan 803 is installed at one end of the working platform 1 by screws, and a blowing pipe 804 is fixedly installed on the top of the blowing fan 803. The blowing pipe 804 is fixedly installed with a protective box on the outside of the heating wire 805 to protect the heating wire 805 and prevent the heating wire 805 from being directly exposed to the outside, which may cause the heating wire 805 to be easily damaged. A heating wire 805 is arranged on the outside of one end of the blowing pipe 804, and air outlet holes are evenly opened on one side of the top of the blowing pipe 804 to facilitate blowing air to the PVC coated cloth, thereby ensuring the rapid drying of the PVC coated cloth after spraying.

[0033] The personnel pass the PVC coated cloth through the top of the plurality of limit rollers 704 and the guide roller 6, and then the PVC coated cloth is retracted and released through the two retracting and releasing mechanisms 2. During the retracting and releasing process of the PVC coated cloth, the water pump 4 is turned on to allow the spraying liquid in the liquid storage tank 3 to enter the inside of the spraying roller 5 to spray the PVC coated cloth;

[0034] During the spraying process, the PVC coated cloth passes through the bottom of the stretching wheel 708. As the PVC coated cloth is retracted and released, the stretching wheel 708 is driven to rotate. The rotation of the stretching wheel 708 makes the two ends of the PVC coated cloth stretch toward each other, so that the flatness of the PVC coated cloth can be ensured during the spraying process of the PVC coated cloth, and the spraying effect of the PVC coated cloth can be ensured, and the problem of poor spraying effect caused by wrinkles of the PVC coated cloth during the spraying process can be avoided. The use of the limiting roller 704 can ensure the stability of the PVC coated cloth during the retraction and release process, and further ensure the spraying effect of the PVC coated cloth. The personnel can start the driving motor 701 to drive the bidirectional threaded rod 702 to rotate, and then drive the moving plate 703 to move, so as to guide and spray PVC coated cloths of different widths, expand the application range of the spraying device, and at the same time, the two ends of the PVC coated cloth can be limited to ensure the stability of the movement of the PVC coated cloth, and avoid the movement of the PVC coated cloth during spraying, which affects the spraying of the PVC coated cloth.

[0035] During the spraying process, the personnel start the electric telescopic column 801 to drive the leveling roller 802 to move to a suitable position. After spraying, the surface of the PVC coated cloth is leveled by the leveling roller 802 to ensure the effect of the PVC coated cloth after spraying, and at the same time, the blowing fan 803 and the heating wire 805 are turned on to blow hot air on the surface of the PVC coated cloth, so that the sprayed paint dries quickly, which is convenient for the subsequent winding of the PVC coated cloth after spraying, and avoids the problem of direct winding of the PVC coated cloth after spraying, which leads to the adhesion of the PVC coated cloth after spraying.
