DETAILED DESCRIPTION

[0036] The following will be combined with the specific implementation of the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] like Figure 1-5 As shown, a water blowing device for coating workpieces of the utility model comprises a support 1, a fixing seat 2, an air pipe 3 and an air nozzle 4.

[0038] The support 1 is fixed to the site of the workpiece water blowing process and is used to carry other components.

[0039] The fixing seat 2 is used to conduct the gas source. The fixing seat 2 is fixedly arranged on the support 1 and is connected to the gas source.

[0040] The air pipe 3 is used to guide the air in the air source. A plurality of air pipes 3 are arranged on the fixed seat 2. One end of the air pipe 3 is sealed and fixed on the fixed seat 2 and is connected to the air source through the fixed seat 2. The other end is located on one side of the workpiece. When the air source is started, the air is blown toward the workpiece through the fixed seat 2 and the air pipe 3 in turn, thereby accelerating the evaporation of moisture on the surface of the workpiece and achieving the effect of drying the workpiece. The air pipe 3 can be bent and shaped along its radial direction to adjust the relative position of the end of the air pipe 3 away from the fixed seat 2 and the workpiece. The end of the air pipe 3 away from the fixed seat 2 is the air outlet of the air pipe 3. When blowing water to different workpieces, or blowing water to different positions of the same workpiece, there are certain differences in the requirements for the air outlet position and angle of the air pipe 3. For example, Figure 2 As shown, since the air pipe 3 can be bent and shaped along its radial direction, the air outlet of the air pipe 3 can be moved to a specified position by bending the air pipe 3, so as to adapt to different working conditions.

[0041] The air nozzle 4 is used to control the gas flow rate. In order to ensure the bending and shaping effect of the air pipe 3, its external dimensions cannot be designed to be too small, which results in a larger area of ​​the air outlet of the air pipe 3, reducing the wind speed and drying effect of the water blowing device. The air nozzle 4 is sealed and fixed at one end of the air pipe 3 away from the fixed seat 2 and is connected thereto. The control of the gas flow rate by the air nozzle 4 can effectively solve this problem.

[0042] When the workpiece is blown dry, in order to provide air outlet effects with different flow rates, the air nozzle 4 includes multiple high-pressure nozzles 41 and multiple normal-pressure nozzles 42. The high-pressure nozzles 41 and the normal-pressure nozzles 42 are sealed and fixed at one end of the air pipe 3 away from the fixed seat 2, and are connected thereto, and the air pipe 3 corresponds to the high-pressure nozzles 41 or the normal-pressure nozzles 42 one by one. When high-pressure airflow is needed, the high-pressure nozzle 41 is used for blowing, and when normal-pressure airflow is needed, the normal-pressure nozzle 42 is used for blowing.

[0043] like Figure 1 As shown, two supports 1 are provided and are arranged on both sides of the workpiece relatively, and a plurality of fixing seats 2 are provided on each support 1. The workpiece is located between the two supports 1. Two sets of air nozzles 4 are used to blow air to both sides of the workpiece simultaneously, so as to improve the drying efficiency of the water blowing device.

[0044] The amount of water accumulated at the bottom of the workpiece is usually greater than that at the top or side of the workpiece. By placing the high-pressure nozzle 41 below the normal-pressure nozzle 42, the uniformity of the workpiece drying process can be ensured. Figure 1 As shown, two rows of air nozzles 4 can be arranged on each support 1, one row is high-pressure nozzles 41, and the other row is normal-pressure nozzles 42, which are selected according to needs.

[0045] The air pipe 3 is preferably a flexible metal air pipe, which can ensure the service life of the air pipe 3 and the entire water blowing device and reduce the use cost of the device.

[0046] In order to improve the water blowing effect, the support 1 is preferably configured to be able to slide back and forth relative to the workpiece, such as Figure 1 and Figure 3 As shown, the support 1 includes a first mounting seat 11, a second mounting seat 12, a third mounting seat 13 and a fourth fixing plate 14, wherein the second mounting seat 12 is fixedly arranged on the first mounting seat 11 in a slidable manner; the third mounting seat 13 is fixedly arranged on the second mounting seat 12 in a slidable manner; the fourth fixing plate 14 is fixedly arranged on the third mounting seat 13 in a slidable manner, and the sliding directions of the second mounting seat 12, the third mounting seat 13 and the fourth fixing plate 14 are perpendicular to each other. For example, the second mounting seat 12 can slide back and forth along the Z axis on the first mounting seat 11, the third mounting seat 13 can slide back and forth along the Y axis on the second mounting seat 12, and the fourth fixing plate 14 can slide back and forth along the X axis on the third mounting seat 13, thereby driving the air nozzle 4 to blow reciprocatingly on the workpiece, thereby improving the drying efficiency of the water blowing device; at the same time, by utilizing the moving effect, the air nozzle 4 can be kept away from the workpiece before and after the workpiece water blowing operation, so as to provide a larger operating space for the disassembly and assembly of the workpiece.

[0047] In order to achieve the above-mentioned movement effect of the support 1, specifically, the first mounting seat 11 includes a first fixed plate 111 and a screw rod 112, the screw rod 112 is rotatably set on the first fixed plate 111, and the second mounting seat 12 is slidably set on the first fixed plate 111 and connected with the screw rod 112 by threaded cooperation. When the screw rod 112 is rotated by a driving device such as a motor, the screw rod 112 can be driven to reciprocate by the threaded cooperation with the second mounting seat 12; correspondingly, the second mounting seat 12 includes a second fixed plate 121 and two first cylinders 122, wherein the second fixed plate 121 is slidably set on the first fixed plate 111 and connected with the screw rod 112 by threaded cooperation; the first cylinder 122 The third mounting seat 13 is fixedly arranged on the second fixing plate 121, and its output end is connected to the third mounting seat 13, and the third mounting seat 13 is driven to reciprocate by the telescopic drive of the first cylinder 122; similarly to the above, the third mounting seat 13 includes a third fixing plate 131 and a second cylinder 132, wherein the two first cylinders 122 are arranged opposite to each other, and a third fixing plate 131 is fixedly arranged on the telescopic end of each first cylinder 122; a second cylinder 132 is fixedly arranged on each third fixing plate 131, and a fourth fixing plate 14 is fixedly arranged on each second cylinder 132, and the reciprocating movement of the fourth fixing plate 14 is also realized by the telescopic control of the second cylinder 132; at the same time, Figure 3 As shown, two groups of fourth fixing plates 14 are arranged in the support 1, which can not only speed up the drying efficiency of the water blowing device, but also allow different types of air nozzles 4 to be installed on the two groups of fourth fixing plates 14, so that different types of air nozzles 4 can be selected according to the needs of the workpiece.

[0048] The use method of the water blowing device for coating workpieces of the utility model is as follows:

[0049] like Figure 1 As shown, first, the workpiece is installed in the middle position of the two supports 1, and then the position and angle of the air nozzle 4 are adapted to the workpiece by bending the air pipe 3, and then the air source is turned on to blow the workpiece dry, and finally the workpiece is removed for subsequent spraying operations; during this period, the air nozzle 4 can be reciprocated on the outside of the workpiece by driving the screw rod 112, the first cylinder 122 and the second cylinder 132 to enhance the blowing effect of the water blowing device.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
