The plurality of rolling components can drive the expansion connector placed obliquely on the outer surface of the folding plate 18 to rotate, thereby cooperating with the spraying parts to quickly rotate and spray paint.

[0019] The first driving mechanism includes two groups of first mounting seats 2, the two groups of first mounting seats 2 are respectively fixedly arranged on both sides of the inner wall of the workpiece frame 1, the inner sides of the two groups of first mounting seats 2 are respectively connected with two first guide rods 5, the two first guide rods 5 are arranged in parallel, an L-shaped table is fixedly arranged on the inner edge of one side of the workpiece frame 1, a first motor 3 is fixedly arranged on the outer side of the L-shaped table, a first screw rod 4 is fixedly arranged on the output end of the first motor 3, and the first screw rod 4 is rotatably connected to the inside of one group of first mounting seats 2, a first slide 16 slides together on the outside of the first screw rod 4 and the two first guide rods 5, and the first slide 16 is threadedly matched with the first screw rod 4; like Figure 1 , Figure 2 and Figure 3 As shown, the first motor 3 drives the first screw rod 4 to rotate, and the first slide 16 drives the external spray-painted parts to move from one end to the other end, thereby simultaneously spraying paint on the expansion connectors placed in the same batch.

[0020] The second driving mechanism includes two groups of second mounting seats 6, the two groups of second mounting seats 6 are respectively fixedly arranged at both ends below one side of the workpiece frame 1, the inner sides of the two groups of second mounting seats 6 are respectively connected with two second guide rods 11, a second motor 14 is fixedly installed on the outer wall of the workpiece frame 1, a second screw rod 7 is fixedly arranged at the output end of the second motor 14, the second screw rod 7 is rotatably connected with the inside of one group of second mounting seats 6, a second slide seat 8 slides together on the outside of the second screw rod 7 and the two second guide rods 11, and the second slide seat 8 is threadedly matched with the second screw rod 7; like Figure 1 and Figure 2 As shown, when the second motor 14 drives the second screw rod 7 to rotate, the second slide seat 8 drives the moving rod 9 to move, so that the moving rod 9, the support rod 10, and the rear plate 12 move toward the painting part after the expansion connector is installed.

[0021] The plurality of rolling components include a rotating shaft 21 rotatably mounted inside the horizontal frame 19, a rotating drum 22 is fixedly sleeved in the middle of the outer side of the rotating shaft 21, a meshing member is arranged below the outer side of the rotating shaft 21, baffles 23 are fixedly mounted on both sides of the upper surface of the horizontal frame 19, the meshing member includes a pinion 20 fixedly sleeved below the outer side of the rotating shaft 21, a slide groove is provided inside the rear plate 12, a rack 29 is slidably mounted inside the slide groove, a cylinder 30 is arranged at one end of the rack 29, and the outer side of the cylinder 30 is connected to the outer edge of one side of the rear plate 12 through an L-shaped rod 28; like Figure 5 and Figure 7 As shown, under the connection of the L-shaped rod 28, the cylinder 30 is installed on one side edge of the rear plate 12. When the cylinder 30 drives the rack 29 to move, the rack 29 will engage with the corresponding pinion 20, thereby driving the rotating drum 22 to rotate, so that the expansion connector attached to the inside of the arc groove 27 rotates, thereby replacing the unpainted area.

[0022] The sliding member includes a plurality of balls 33, which are arranged at equal distances in the transverse direction on the inner surface of the T-shaped plate 24; like Fig. 9 As shown, when the expansion connector rotates, the ball 33 can support the lower end surface and rotate in coordination.

[0023] The paint spraying part includes a tube clamping platform 17 fixedly mounted on the outside of the first slide 16, a paint spraying tube 13 is fixedly clamped inside the tube clamping platform 17, a branch pipe 31 is obliquely connected to the upper side of the paint spraying tube 13 and close to the tube clamping platform 17, and a nozzle 32 is symmetrically connected and installed inside the branch pipe 31; like Figure 1 , Figure 2 and Figure 8As shown, the raised side of the T-shaped plate 24 is to prevent the expansion connector from being separated from the ball 33 when rotating, so it is clamped at the outer edge, and the ball 33 is used in conjunction with the rotating drum 22. When the rotating drum 22 causes the expansion connector to rotate through its own contact resistance, the ball 33 rotates in conjunction with the lower end of the inclined expansion connector; The branch pipe 31 is inclined, and the spraying direction of the nozzle 32 is perpendicular to the inclined expansion connector. Therefore, when the nozzle 32 sprays liquid, the paint liquid can be sprayed forward to the surface of the expansion connector in the maximum range.

[0024] Vertical rods 36 are fixedly installed on the upper surfaces of both sides of the folding plate 18, and a slide bar 25 is slidably installed on the outside of the two vertical rods 36. A plurality of material-smoothing shells 15 are installed on the upper surface of the slide bar 25, and the plurality of material-smoothing shells 15 correspond to the positions of the corresponding arc grooves 27. A clamping sleeve 26 is fixedly installed on the upper part of the vertical rod 36, and the lower end of the slide bar 25 is movably against the clamping sleeve 26. A connecting rod 35 is fixedly installed on the upper end of the vertical rod 36, and an elastic sheet 34 is fixedly installed on the outer side of the plurality of connecting rods 35; like Figure 4 , Figure 6 and Fig. 9 As shown, the slide bar 25 slides outside the vertical bar 36, which can drive the multiple material-following shells 15 to move, and when loading, it helps to quickly put the corresponding expansion connectors into the corresponding positions from above the horizontal frame 19; The clamping sleeve 26 is provided to clamp the lower end of the material casing 15 when it moves outside the slide rod 25, so as to guide the expansion connector to be placed obliquely on the inner surface of the arc groove 27; When the material loading is completed, the slide bar 25 is moved upward so that the slide bar 25 squeezes the elastic sheet 34 , thereby preventing the paint from being sprayed on the outer surface of the expansion connector due to the obstruction of the material feeding shell 15 during the operation.

[0025] Working principle: When in use, slide the slide bar 25 to above the outer sleeve 26 of the vertical rod 36, so that each group of material shells 15 can correspond to the arc groove 27 on the folding plate 18, so that the worker can quickly place the expansion connector to be processed in the arc groove 27 inside the folding plate 18, so that the lower end surface of the expansion connector is tilted and the bottom is in contact with the ball 33, and then move the material shell 15 upward to separate the material shell 15 from the expansion connector. When the slide bar 25 moves to the elastic sheet 34, the elastic sheet 34 can be stuck in the inside of the slide bar 25, and then the material shell 15 is stuck on the top of the vertical rod 36. The purpose is to prevent the expansion connector from being blocked when it is painted, and then through the movement of the second drive mechanism, The moving rod 9 is close to the nozzle 32, the paint spraying pipe 13 is connected with the external paint spraying equipment, and the paint liquid is sprayed onto the outer surface of the expansion connector through the nozzle 32. The first driving mechanism can drive the first slide 16 and the tube clamping platform 17 to move from one end to the other end. At the same time, the cylinder 30 can drive the rack 29 to reciprocate inside the slide groove during this process. The movement of the rack 29 is engaged with the pinion 21 at the lower end of the rotating shaft 20, thereby prompting the rotating drum 22 to rotate. The expansion connector that fits the outer surface of the rotating drum 22 can rotate synchronously with the rotating drum 22, and its outer surface is rotated, so that during the painting process, each group of expansion connectors can be evenly sprayed. Finally, the expansion connector that has been painted is removed, and then the next batch of expansion connectors are operated.

[0026] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
