DETAILED DESCRIPTION

[0023] The following is a combination of the appended examples of the present invention Figure 1-6 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0024] As shown in the figure, a paint spraying device for fuel filter production includes a frame 1, on which a conveying mechanism 2 and a paint spraying mechanism 3 are provided. The conveying mechanism 2 includes a conveying chain 21, a clamping assembly 22 and a rack 23. The conveying chain 21 is provided on the frame 1 and is transmission-connected to a motor 24 provided on the frame 1. Several of the clamping assemblies 22 are arranged on the conveying chain 21 at intervals. The clamping assembly 22 includes a mounting seat 221, a rotating shaft 222, a clamping seat 223 and a gear 224. The mounting seat 221 is fixedly connected to the conveying chain 21, and the rotating shaft 222 is vertically rotatably provided on the mounting seat 221. The clamping seat 223 is fixedly connected to the conveying chain 21. A clamping cavity 2231 is provided on the end surface of the clamping seat 223 and connected to one end of the rotating shaft 222. A plurality of clamping blocks 225 that can slide radially along the clamping cavity 2231 are provided on the inner wall of the clamping cavity 2231. A spring 226 is provided between the clamping block 225 and the clamping seat 223. The clamping block 225 can protrude from the inner wall of the clamping cavity 2231 under the action of the spring 226. The gear 224 is fixedly connected to the other end of the rotating shaft 222. The rack 23 is provided on one side of the moving path of the gear 224 and can engage with the gear 224. The paint spraying mechanism 3 includes a paint spray nozzle 31, which is provided on the frame 1 and is located on one side of the moving path of the clamping assembly 22.

[0025] Specifically, the structure of the clamping block 225 slidingly arranged on the inner wall of the clamping cavity 2231: the inner wall of the clamping cavity 2231 is provided with a plurality of sliding grooves 2232 that penetrate the clamping seat 223 outward and match the clamping block 225, the side wall of the sliding groove 2232 is provided with a limiting groove 2233 that penetrates the clamping seat 223 outward, and the side of the clamping block 225 is formed with a limiting block 2251 that matches the limiting groove 2233. The clamping block 225 is placed in the sliding groove 2232 so that the limiting block 2251 is kept in the limiting groove 2233. The clamping seat 223 is externally screwed with a mounting sleeve 2232 that covers the port of the sliding groove 2232. 27. The spring 226 is arranged in the sliding groove 2232 and is located between the clamping block 225 and the mounting sleeve 227. The clamping block 225 can slide in the sliding groove 2232 under the action of the spring 226, so that the inner side surface of the clamping block 225 protrudes from the inner wall of the clamping cavity 2231. At the same time, the limit block 2251 keeps sliding in the limit groove 2233 to ensure that the clamping block 225 will not fall out of the sliding groove 2232. In addition, by screwing the mounting sleeve 227 on the clamping seat 223, the spring 226 and the clamping block 225 are limited after assembly, which facilitates the disassembly and assembly of the clamping block 225 and facilitates the maintenance of the clamping block 225 in subsequent use.

[0026] In the above embodiment, when the fuel filter is sprayed with paint, the fuel filter is first fixed to the clamping assembly 22. The specific operation is to align the connecting pipe of the fuel filter (for the sake of convenience, simply referred to as the connecting pipe) with the clamping cavity 2231 and insert it into the clamping cavity 2231. During the process of inserting the connecting pipe into the clamping cavity 2231, the connecting pipe pushes the plurality of clamping blocks 225 to slide outward in the sliding groove 2232 and compress the spring 226. After the connecting pipe is inserted into the clamping cavity 2231, the plurality of clamping blocks 225 surround the circumference of the connecting pipe and, under the action of the spring 226, press tightly against the circumferential side of the connecting pipe, thereby clamping the connecting pipe and keeping it in the clamping cavity 2231, thereby achieving the clamping and fixing of the fuel filter on the clamping assembly 22. At the same time, the motor 24 drives the conveying chain 21 to move, and the conveying chain 21 drives the clamping assembly 22 to move through the mounting seat 221, thereby driving the fuel filter The fuel filter moves. In the process of the clamping assembly 22 driving the fuel filter to move, the gear 224 is engaged with the rack 23. Under the cooperation of the gear 224 and the rack 23, the clamping assembly 22 causes the rotating shaft 222 to rotate while moving, and the rotating shaft 222 drives the clamping seat 223 and then drives the fuel filter to rotate. When the moving and rotating fuel filter moves past the side of the paint spray nozzle 31, the paint sprayed from the paint spray nozzle 31 is evenly sprayed onto the fuel filter in coordination with the movement and rotation of the fuel filter, thereby realizing the painting operation of the fuel filter, and the paint spraying is very uniform, ensuring the quality of the painting operation. In the above manner, multiple fuel filters fixed on the clamping assembly 22 move and rotate with the conveyor chain 21 from the side of the paint spray nozzle 31, so that the painting operation can be carried out continuously, and the operation of painting the fuel filter and fixing it on the clamping assembly 22 can be carried out simultaneously, thereby improving the efficiency of the painting operation.

[0027] Preferably, a clamping groove 2252 is provided on the inner side surface of the clamping block 225, and the clamping groove 2252 matches the flange formed on the connecting pipe (the flange is used to limit the hose when the hose is plugged into the connecting pipe). When the clamping block 225 is tightly against the peripheral side surface of the connecting pipe, the flange is stuck in the clamping groove 2252. The limiting effect of the clamping groove 2252 on the flange enhances the stability of the fuel filter when it is fixed to the clamping assembly 22, thereby enhancing the stability of the fuel filter when it moves and rotates with the clamping assembly 22.

[0028] Furthermore, the conveying mechanism 2 also includes a rear cover 25 and a front cover 26. The rear cover 25 is fixedly arranged on the frame 1, and the conveying chain 21, the mounting seat 221, the gear 224 and the rack 23 are arranged in the rear cover 25. The front cover 26 is arranged on the frame 1 opposite to the rear cover 25. A moving gap 27 is formed between the rear cover 25 and the front cover 26 for the rotating shaft 222 to move, and the rotating shaft 222 passes through the moving gap 27.

[0029] In the above preferred embodiment, the front cover 26 and the rear cover 25 cooperate to place the conveyor chain 21, the rack 23 and the gear 224 in a relatively closed working environment, reducing the impact of the paint on the above-mentioned transmission components during the painting operation, thereby ensuring the stability of the conveying mechanism 2 when driving the fuel filter to move and rotate, and the moving gap 27 guides the rotating shaft 222 as it moves with the conveyor chain 21, thereby enhancing the stability of the fuel filter when it moves and rotates, and thus ensuring the quality of the painting.

[0030] Preferably, a first support plate 251 and a second support plate 261 are respectively formed in the rear cover 25 and the front cover 26, which are located below the mounting seat 221 and abut against the mounting seat 221. The first support plate 251 and the second support plate 261 play a supporting role when the mounting seat 221 moves with the conveyor chain 21, thereby ensuring the stability of the clamping assembly 22 when it moves, and further ensuring the stability of the fuel filter when it moves and rotates.

[0031] Preferably, the paint spraying mechanism 3 also includes a paint spraying room 32, which is arranged on the frame 1 on one side of the moving path of the clamping assembly 22, and the paint spraying nozzle 31 is arranged in the paint spraying room 32. The paint spraying room 32 enables the paint spraying nozzle 31 to perform a paint spraying operation on the moving and rotating fuel filter in a relatively closed environment, thereby reducing the impact of the paint spraying operation on the external environment.

[0032] Furthermore, the frame 1 is also provided with a drying mechanism 4 located behind the paint spraying mechanism 3 along the moving path of the clamping assembly 22. The drying mechanism 4 includes a drying chamber 41 and a heating pipe. The drying chamber 41 is arranged on the frame 1 on one side of the paint spraying chamber 32 and is connected to the paint spraying chamber 32. The heating pipe is arranged in the drying chamber 41.

[0033] In the above preferred embodiment, the fuel filter that moves and rotates along with the conveyor chain 21 passes through the paint spraying room 32 to complete the painting operation, and then enters the drying room 41. The heating pipe dries the paint on the fuel filter that has completed the painting and keeps moving and rotating, thereby improving the efficiency of the painting operation.

[0034] Furthermore, the frame 1 is also provided with a unloading mechanism 5 located behind the drying mechanism 4 along the moving path of the clamping component 22, and the unloading mechanism 5 includes a unloading plate 51, which is obliquely arranged on the frame 1 and located below the clamping component 22. The unloading plate 51 is provided with a unloading trough 511 extending along the moving path of the clamping component 22 and aligned with the clamping component 22, and the frame 1 is provided with a unloading port 11 located below the unloading plate 51.

[0035] In the above preferred embodiment, after the fuel filter moving with the conveying chain 21 completes drying after passing through the drying chamber 41, the rotating shaft 222 enters the discharge chute 511 through the port of the discharge chute 511, so that the discharge plate 51 is located between the clamping seat 223 and the fuel filter body. In the process of the fuel filter continuing to move with the conveying chain 21, since the discharge plate 51 is arranged at an angle, the lower surface of the discharge plate 51 conflicts with the fuel filter body, and the fuel filter moves downward along the discharge plate 51, and the connecting pipe gradually disengages from the clamping cavity 2231. After the connecting pipe completely disengages from the clamping cavity 2231, the fuel filter is separated from the clamping assembly 22 and falls through the drop port 11, thereby realizing the discharge of the fuel filter and improving the efficiency of the painting operation.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
