Description

Technical Field

[0001] This utility model relates to the technical field of electrostatic spraying equipment, specifically to a workpiece hanging mechanism for an electrostatic spraying line. Background Technology

[0002] Electrostatic powder coating is a method where the coating material is sprayed from an electrostatic powder spray gun. During dispersion, the powder particles become negatively charged. These charged particles, under the influence of airflow (or centrifugal force, or other forces) and electrostatic attraction, adhere to the grounded substrate, where they are then heated and cured to form a film. Electrostatic powder coating is the dominant powder coating method in the industrial coating field.

[0003] The workpiece hanging mechanism is a core component connecting workpiece conveying and spraying operations. Its performance directly affects spraying efficiency, coating quality, and the continuous operation capability of the equipment. Existing hanging mechanisms often have a single working surface design for the hanging head. During spraying, paint powder easily accumulates on the working surface of the hanging head, leading to defects such as coating thickness deviation, pinholes, and runs. In such cases, the machine must be stopped for cleaning the hanging head, which also causes wear and tear on the head, shortening its service life.

[0004] Therefore, to address the issue of wear and tear caused by repeated cleaning, a workpiece hanging mechanism for electrostatic spraying lines is proposed to solve the problems of a single working surface and short service life. Utility Model Content

[0027] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a workpiece hanging mechanism for an electrostatic spraying line, including a support column 1.

[0029] like Figure 1 and Figure 2 As shown, four support columns 1 are provided in a rectangular arrangement, providing stable support for the entire mechanism. A transmission assembly 2 is fixedly mounted on the top of each support column 1. The transmission assembly 2 includes a mounting top plate 201. A mounting base plate 202 is fixed on the support column 1 below the mounting top plate 201. A sealing plate 203 is fixed between the mounting top plate 201 and the mounting base plate 202. The sealing plate 203 is located at the outer edge of the mounting base plate 202 and prevents external dust and impurities from entering the transmission assembly 2 and affecting the normal operation of the transmission components. The mounting base plate 202 has an annular guide hole 2021 and a guide groove 2022. The guide hole 2021 is located near the inner edge of the mounting base plate 202, and the guide groove 2022 is located between the guide hole 2021 and the sealing plate 203.

[0030] A plurality of pulleys 204 are rotatably connected to the mounting base plate 202. The pulleys 204 are located on the side of the guide slide hole 2021 away from the guide groove 2022. The other end of each pulley 204 is rotatably connected to the mounting top plate 201. The pulleys 204 are evenly distributed around the mounting base plate 202. A synchronous belt 205 is fitted onto each pulley 204, forming a belt drive with the pulleys 204. One of the pulleys 204 is connected to a drive motor 206, which is fixed above the mounting top plate 201. The input end of the drive motor 206 is connected to an external power source, and the output end of the drive motor 206 passes through the mounting top plate 201 and is connected to the pulley 204 via a coupling, thereby driving the pulley 204 to rotate.

[0031] like Figure 1-5As shown, the guide hole 2021 is slidably connected to several hanging components 3, providing a moving path for the hanging components 3. Each hanging component 3 includes a fixing block 301, which is fixed to the outside of the synchronous belt 205. The synchronous belt 205 drives the fixing block 301 to rotate. A connecting post 302 is welded to the side of the fixing block 301 away from the synchronous belt 205. A pulley 303 is rotatably connected to the side of the connecting post 302 away from the fixing block 301. The pulley 303 slides in engagement with the guide groove 2022. The hanging component 3 is connected to the synchronous belt 205 via the fixing block 301. When it moves with the synchronous belt 205, the pulley 303 contacts and rolls with the guide groove 2022, converting the sliding friction between the hanging component 3 and the mounting base plate 202 into rolling friction.

[0032] The connecting column 302 is fixedly connected to the main shaft 304, which is located between the pulley 303 and the fixing block 301. The main shaft 304 passes through the mounting base plate 202 through the guide sliding hole 2021. A limiting block 305 is fixed at one end of the main shaft 304 away from the connecting column 302. Several rectangular grooves are evenly distributed around the circumference on the outer wall of the limiting block 305. An elastic pressure block 3051 is fixed in the rectangular groove. The elastic pressure block 3051 has a spring inside and rubber on the outside. When the rubber part is under pressure, the spring contracts and the elastic pressure block 3051 is pressed into the rectangular groove. The end of the limiting block 305 away from the main shaft 304 is fixedly connected to a rotating component 306. The rotating component 306 includes a fixed shaft 3061, and a servo motor 3062 is fixed inside the fixed shaft 3061. The output shaft of the servo motor 3062 passes through the fixed shaft 3061 and is fixedly connected to a rotating disk 3063. The rotating disk 3063 is rotatably connected below the fixed shaft 3061. A rotating body 3064 is detachably installed on the top of the rotating disk 3063. The rotating body 3064 surrounds the outside of the fixed shaft 3061. The rotating body 3064 has several grooves 3065 inside. The grooves 3065 are located at the same horizontal position as the elastic pressure block 3051 and are equal in number. When the rotating body 3064 rotates, the elastic pressure block 3051 is squeezed and contracted until it is locked into the next groove 3065. Several hanging rings 307 are fixed on the outer side of the rotating body 3064. The hanging rings 307 are evenly distributed on each surface of the rotating body 3064 and are used to suspend the workpiece to be sprayed.

[0033] A control module 4 is fixed on the outer surface of the support column 1 away from the drive motor 206. The control module 4 faces the side through which the hanging assembly 3 passes. The control module 4 is at the same height as the rotating assembly 306. The control module 4 is equipped with a sensing device and a PLC control board. When the hanging assembly 3 passes the control module 4, the control module 4 controls the operation of the servo motor 3062 through a remote signal. The servo motor 3062 drives the rotating disk 3063 to rotate the rotating body 3064 by a certain angle until the elastic pressure block 3051 is inserted into the next groove 3065, completing the switching of the working surface.

[0034] A cleaning assembly 5 is fixed to the side of the mounting base plate 202 away from the mounting top plate 201. The cleaning assembly 5 is adjacent to the control module 4. The cleaning assembly 5 includes a fixing plate 501, which is fixed to the mounting base plate 202 and extends downward. Several brushes 502 are installed on the side of the fixing plate 501 facing the material hanging assembly 3. A dust collection fan 503 is fixed to the side of the fixing plate 501 away from the mounting base plate 202 by bolts. A dust collection box 504 is connected to the bottom of the dust collection fan 503 by a hose, and the dust collection box 504 is fixed to the fixing plate 501.

[0035] Working principle: During use, the operator suspends and fixes the workpiece to be sprayed on the hanging ring 307. At this time, the elastic pressure block 3051 on the outside of the limiting block 305 initially fits into the groove 3065 of the rotating body 3064. After the hanging is completed, the drive motor 206 is started to drive the pulley 204 to rotate, which drives the synchronous belt 205 to form a closed-loop belt drive. The hanging assembly 3 fixed on the outside of the synchronous belt 205 moves synchronously with the synchronous belt 205. During the movement, the pulley 303 rolls in the guide groove 2022 to reduce resistance; at the same time, the guide sliding hole 2021 and the guide groove 2022 together restrict the movement trajectory of the hanging assembly 3 until it moves to the spraying station. After the spraying work is completed, the workpiece is removed, and the hanging assembly 3 continues to move.

[0036] When the material hanging assembly 3 moves to the vicinity of the control module 4 along with the synchronous belt 205, the control module 4 senses the material hanging assembly 3 and sends a command signal to start the servo motor 3062, driving the rotating disk 3063 to rotate, further causing the rotating body 3064 to rotate synchronously. When it rotates to a preset angle, the elastic block 3051, under its own elastic action, gets stuck into the next groove 3065, completing the switching of the working surface of the rotating body 3064. Then the material hanging assembly 3 continues to move forward to the cleaning assembly 5. The cleaning assembly 5 uses the brush 502 and the vacuum fan 503 to perform preliminary cleaning on the surfaces of the rotating body 3064 other than the working surface, until all working surfaces of the rotating body 3064 are free of powder. Then the rotating body 3064 is disassembled for further cleaning.
