However, most existing nonwoven fabric finishing spraying equipment has limited functions, and parameters such as nozzle angle and spray concentration are difficult to adjust flexibly, failing to meet the needs of preparing nonwoven fabrics with specific local functions. Furthermore, the emulsion is prone to solidification and clogging of the nozzle at low temperatures, affecting spraying effect and equipment stability. In addition, the equipment lacks self-cleaning functions, resulting in high maintenance costs and low production efficiency.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0028] like Figures 1 to 6 As shown, a nonwoven fabric post-treatment spraying device includes a frame, on which a spray pipe 11 is rotatably mounted. Multiple nozzles 12 are arranged on the spray pipe 11. One end of the spray pipe 11 is connected to a rotary drive device, and the other end is connected to a metering pump 21. The metering pump 21 is connected to a storage tank 22. A main valve 13 is installed on the side of the spray pipe 11 near the metering pump 21. The rotary drive device includes a drive motor 31 mounted on the frame; the drive motor 31 is a servo motor. A transmission gear set is installed between the power output shaft of the drive motor 31 and the spray pipe 11.

[0029] During operation, the metering pump 21 pumps the liquid in the storage tank 22 into the spray pipe 11, which forms a spray through the nozzle 12 and is sprayed onto the non-woven fabric located below the nozzle 12. The drive motor 31 drives the spray pipe 11 to rotate through the transmission gear set, and the spray pipe 11 drives the nozzle 12 to swing, thereby realizing flexible adjustment of the spray angle, expanding the spray range of the nozzle 12, and improving the controllability and flexibility of the spray device; it can adapt to the needs of different working scenarios.

[0030] The power output shaft of the drive motor 31 is arranged parallel to the spray pipe 11. The transmission gear set includes a first gear 32 fixedly installed on the power output shaft, and a second gear 33 that meshes with the first gear 32 is installed on the spray pipe 11.

[0031] Alternatively, the power output shaft of the drive motor 31 is perpendicular to the spray pipe 11. The transmission gear set includes a first gear 32 fixedly mounted on the power output shaft, a second gear 33 mounted on the spray pipe 11, and a steering gear drivingly connecting the first gear 32 and the second gear 33. The steering gear includes a third gear 34 and a fourth gear 35 coaxially arranged and fixedly connected. The third gear 34 meshes with the first gear 32, and the fourth gear 35 meshes with the second gear 33. Figure 5 As shown, the first gear 32 and the third gear 34 are a bevel gear set; or, as... Figure 6 As shown, the third gear 34 is an end gear, which meshes with the first gear 32 for transmission.

[0032] When the power output shaft of the drive motor 31 is parallel to the spray pipe 11, the torque output by the drive motor 31 is in the same direction as the rotational torque of the spray pipe 11. The torque of the drive motor 31 can be transmitted to the spray pipe 11 by direct meshing of the first gear 32 and the second gear 33. By setting the specifications of the first gear 32 and the second gear 33, the speed change of the torque can be controlled. In order to rationally plan the spatial layout of the device, the output shaft of the drive motor 31 and the spray pipe 11 may also be perpendicular. When the two are set perpendicularly, a steering gear needs to be set between the first gear 32 and the second gear 33, such as... Figure 5 and Figure 6 As shown, the output torque of the drive motor 31 can be converted into the rotational torque of the spray pipe 11 through the action of the rotating gear, thus realizing torque transmission. The flexible design of the transmission gear set can adapt to different structural designs.

[0033] In one specific embodiment, the frame includes a crossbeam 41 located above the nonwoven fabric, and the spray pipe 11 is rotatably mounted on the crossbeam 41. The crossbeam 41 has a groove 42 facing the nonwoven fabric, and the spray pipe 11 is installed within the groove 42. The crossbeam 41 serves as a support for the spray pipe 11, facilitating its installation and rotation. The spray pipes 11 are distributed parallel to the crossbeam 41, positioning the nozzle 12 directly above the nonwoven fabric, facilitating adjustment of the spray angle of the nozzle 12.

[0034] Furthermore, multiple clamps (not shown in the figure) are distributed and installed on the crossbeam 41 to limit the position of the spray pipe 11. The clamps bind the spray pipe 11 within the groove 42 of the crossbeam 41. The tightness of the clamps can be adjusted according to the specifications of the spray pipe 11 to ensure the rotational freedom of the spray pipe 11. The structure of the clamps can adopt existing technology, and the clamps are low in cost. Using clamps to bind the spray pipe 11 can help reduce the cost of the device.

[0035] In one specific embodiment, the bottom width of the groove 42 is smaller than the width of its opening end, that is, the two side walls of the groove 42 are outwardly inclined slopes from the bottom wall of the groove 42 to the opening end, and the cross-section of the groove 42 is trapezoidal; this can avoid interference between the nozzle 12 and the side wall of the groove 42 when the spray pipe 11 rotates, and increase the degree of freedom of the nozzle 12 in angle adjustment.

[0036] In one specific embodiment, an electric auxiliary heating device is provided on the outer wall of the spray pipe 11, and a temperature sensor is installed inside the spray pipe 11. The electric auxiliary heating device and the temperature sensor are connected to a temperature controller. The electric auxiliary heating device includes an electric heating wire wrapped around the outer wall of the spray pipe 11, and a heating switch is installed between the electric heating wire and the power supply. The heating switch is connected to the temperature controller. The temperature controller can be a programmable logic device, such as a microcontroller, which is prior art and will not be described further.

[0037] A temperature sensor can be installed at the inlet of the spray pipe 11. When liquid enters the spray pipe 11, the temperature sensor detects the liquid temperature and transmits it to the temperature controller. The temperature controller determines whether the temperature is too high or too low. When the temperature is too low, the temperature controller controls the electric auxiliary heating device to work, instantly heating the liquid in the spray pipe 11 to prevent poor processing results in the nonwoven fabric post-processing due to excessively low liquid temperature. The heating speed can be adjusted by regulating the working power of the electric heating wire.

[0038] In one specific embodiment, the spray pipe 11 is also connected to an air jet pipe 51, which is connected to a high-pressure air pump 52. An air jet valve 53 is installed on the air jet pipe 51. When the spray pipe 11 or the nozzle 12 is blocked, the main valve 13 of the device can be closed, and the air jet valve 53 and the high-pressure air pump 52 can be opened to inject high-pressure gas into the spray pipe 11 and the nozzle 12, thereby clearing the blockage with the high-pressure gas.

[0039] In one specific implementation, a solenoid valve 14 is installed on the nozzle 12. The control terminal of the solenoid valve 14 is connected to a spray controller (not shown in the figure). The spray controller uses a programmable logic device, such as a microcontroller, which is prior art and will not be described in detail here. When it is necessary to spray a local area, some nozzles 12 need to be closed. At this time, the spray controller controls the solenoid valve 14 to close the corresponding nozzles 12. Under the control of the spray controller and the solenoid valve 14, the nozzles 12 can also be controlled to work in turn. For example, the nozzles 12 in odd-numbered positions work first, while the nozzles 12 in even-numbered positions are closed; then the nozzles 12 in even-numbered positions work again, while the nozzles 12 in odd-numbered positions are closed.

[0040] In one specific embodiment, the storage tank 22 is provided with multiple feed inlets 6, each of which is equipped with an electronic weighing sensor (not shown in the figure). The signal output terminal of the electronic weighing sensor is connected to a feed controller. Each feed inlet 6 is equipped with a door, and the door is connected to a cylinder that controls its opening and closing. The control terminal of the cylinder is connected to the feed controller. The feed controller uses a programmable logic device, such as a microcontroller, which is prior art and will not be described in detail here. The electronic weigher weighs the material entering through the feed inlet 6. Once the set weight is obtained, the feed controller controls the cylinder to close the door at the feed inlet 6.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
