Abstract
Description
Technical Field
[0001] The present application relates to the field of powder spraying, and specifically to a reciprocating powder spraying mechanism. Background Art
[0002] Currently, powder spraying refers to a surface treatment method in which plastic powder is charged by an electrostatic generator and sprayed onto parts under the action of an electric field. Its working principle is as follows: The plastic powder is atomized by a high-voltage electrostatic device using the corona discharge principle, and the atomized coating is negatively charged under the action of a high-voltage direct current electric field. Under the action of the electric field, the powder spraying mechanism can spray the coating onto the positively charged workpiece surface. The powder will be evenly adsorbed on the workpiece surface to form a powdery coating. After the powdery coating is baked at high temperature, it will level and cure, and the plastic particles will melt into a dense final protective coating with different effects, firmly adhering to the workpiece surface. This method has the advantages of advanced technology, energy saving and high efficiency, safety and reliability, bright color, etc.
[0003] However, the existing powder spraying mechanisms have the following defects: The spraying parts generally move reciprocally up and down for powder spraying operations. For some non-standard workpieces, such as L-shaped and Z-shaped workpieces, etc., there will be a large space between various parts of these non-standard workpieces, resulting in an empty spraying phenomenon of the spraying parts, causing material waste, and it is difficult to control the powder spraying time for each part of the non-standard workpiece. For example, the horizontal parts will have uneven powder spraying due to insufficient powder spraying time.
[0004] Therefore, how to improve the existing powder spraying mechanism to overcome the above deficiencies is an urgent problem for those skilled in the art to solve. Summary of the Invention
[0005] An object of the present application is to provide a reciprocating powder spraying mechanism that can avoid empty spraying, reduce material waste, has sufficient powder spraying time, and uniform spraying.
[0006] To achieve the above object, the technical solution adopted in the present application is as follows: A reciprocating powder spraying mechanism includes a support base, a linear slide rail, a spraying assembly, a winding assembly, and a feeding pipe. The middle part of the linear slide rail is rotatably connected to the support base; the spraying assembly is arranged on the slider of the linear slide rail, so that the spraying assembly can move to any position on the spraying surface of the workpiece along with the rotation of the linear slide rail and the rotation of the slider; the winding assembly is arranged on the support base; one end of the feeding pipe is communicated with the spraying assembly and the other end is wound on the winding assembly.
[0007] As a preference, the spraying assembly includes a housing, a plurality of spraying members, and a first driving member. The housing is disposed on the slider; the plurality of spraying members are rotatably disposed on the end surface of the housing away from the slider at equal intervals along the circumference of the slider; the first driving member is disposed inside the housing and is used to drive the plurality of spraying members to rotate simultaneously towards the inner or outer side of the housing. The advantage is that this enables the spraying angle of the spraying members to be adjusted to adapt to workpieces of different widths, further improving the versatility and spraying uniformity.
[0008] As a preference, a plurality of rotating grooves are provided through the housing; the spraying member includes a rotating disk, a spray head, and a connecting pipe. The rotating disk is axially rotatably connected in the rotating groove; one end of the spray head is disposed on the rotating disk outside the housing; the connecting pipe is disposed on the rotating disk inside the housing and both ends are respectively communicated with the spray head and the material conveying pipe. The advantage is that it realizes the rotational connection between the spray head and the housing and the communication with the material conveying pipe, and at the same time is connected through the rotating disk, which is convenient for sealing with the rotating groove to prevent plastic powder from entering the housing.
[0009] As a preference, the first driving member includes a driving disk, a plurality of driving grooves, and a driving motor. The driving disk is axially rotatably connected inside the housing; the plurality of driving grooves are provided through the driving disk and are respectively slidably connected to each connecting pipe; the driving motor is disposed inside the housing and is used to drive the driving grooves to rotate with the driving disk, and then drive the spraying members to rotate with the connecting pipes through the driving grooves. The advantage is that this realizes driving a plurality of spray heads to rotate with a plurality of connecting pipes simultaneously. In addition, using the driving motor for driving enables the spraying angle of the spray heads to be arbitrarily adjusted during the spraying process, so that the spraying range further adapts to the shapes of different parts of the workpiece.
[0010] As a preference, the winding assembly includes a winding disk, a second driving member, and a rotary joint; the winding disk is axially rotatably disposed on the support seat; the second driving member is disposed on the support seat and is used to drive the winding disk to rotate until the material conveying pipe is completely wound; the rotary joint is disposed at the center of the winding disk and one end is communicated with the material conveying pipe. The advantage is that it realizes the winding function of the material conveying pipe, and at the same time connects the material conveying pipe and the external pipeline through the rotary joint to avoid interfering with the rotation of the winding disk.
[0011] As a preference, the second driving member includes a base, a mounting shaft and an elastic member. The base is disposed on the support seat; the mounting shaft is disposed on the base and is used for rotatably mounting the winding disc; the elastic member is disposed on the base and is used for forcing the winding disc to rotate to wind the feeding pipe. The advantages are as follows: during use, when the slider moves away from the winding disc, the feeding pipe is pulled out, forcing the winding disc to rotate and simultaneously forcing the elastic member to deform. When the slider moves towards the winding disc, the elastic member recovers its deformation and forces the winding disc to rotate to wind the feeding pipe, realizing the automatic winding and unwinding of the feeding pipe, which is convenient to use.
[0012] As a preference, the winding assembly further includes a winding rod. The winding rod is slidably connected to the chute of the winding disc along the axial direction of the mounting shaft, and one end of the winding rod extends to the outside of the winding disc and the other end is threadedly connected to the mounting shaft. Thus, when the winding disc winds the feeding pipe, the winding rod moves simultaneously, pushing the feeding pipe to be spirally wound on the winding disc; the outer ring surface of the winding disc is provided with a spiral structure and a connecting groove for connecting and restricting the misaligned movement of the feeding pipe spirally wound on the winding disc. The advantages are as follows: through the cooperation of the winding rod and the connecting groove, the feeding pipe is evenly wound on the winding disc, avoiding the feeding pipe from slipping out of the winding disc.
[0013] As a preference, the slider is provided with a fixing block for fixing the feeding pipe, and arc-shaped grooves for guiding the bending of the feeding pipe when the slider slides are provided on the fixing blocks on both sides of the feeding pipe. The advantages are as follows: this enables the fixing block to pull the feeding pipe along with the movement of the slider, and at the same time, in cooperation with the arc-shaped grooves, the feeding pipe is bent, avoiding the folding phenomenon when the feeding pipe is pulled and bent, which may cause the blockage and sealing of the feeding pipe.
[0014] Compared with the prior art, the beneficial effects of the present application are as follows: during use, the support seat is installed on the powder spraying production line. Before spraying different workpieces, according to the shape of the workpiece, the rotation process of the linear slide rail and the sliding process of the slider are set, and the winding and unwinding of the feeding pipe are coordinated by the winding assembly to avoid interfering with the operation of the device, so that the movement track of the spraying assembly is adapted to the shape of the workpiece, enabling it to be adapted to a variety of workpieces, with high versatility. Furthermore, during the spraying process of the spraying assembly, the phenomenon of empty spraying is avoided, reducing material waste; when the spraying assembly is reset after spraying the workpiece, it can not only perform a second spraying on the workpiece, making the powder spraying time more sufficient and the spraying more uniform, but also facilitating the spraying operation of the next workpiece, with high coherence in the spraying process. It can be seen that this reciprocating powder spraying mechanism avoids the phenomenon of empty spraying, reduces material waste, has sufficient powder spraying time, and the spraying is uniform.
