[0026] Example

[0027] The present embodiment provides a paint box positioning device for a paint filling machine, the paint filling machine includes a frame 1, and an outlet 2 for outputting paint, the positioning device includes a conveying device arranged in front of the outlet 2 for transmitting the paint box, the conveying device includes a conveyor belt 3 and a positioning structure 4 arranged on the side of the outlet 2 for positioning the paint box, the positioning structure 4 includes a baffle assembly 5 and a driving device 6 for driving the baffle assembly 5 to move, the baffle assembly 5 has a positioning state horizontally arranged on the side of the paint box and a evasive state retracted backward to allow the paint box to pass through the conveyor belt 3, and the driving device 6 is used to control the baffle assembly 5 to switch back and forth between the positioning state and the evasive state.

[0028] The above specific improvements are: Figures 1 - 3As shown, the pigment filling machine includes a frame 1 and a discharge port 2, and a barrel is connected above the discharge port 2. The pigment in the barrel flows out through the discharge port 2 and is filled into the pigment box. During the filling process, the conveyor belt 3 is in a state of continuous transmission. Compared with the prior art, the driving device 6 drives the baffle assembly 5 to move, and the driving device 6 can perform periodic reciprocating motion. When the driving device 6 completes a cycle, it will drive the baffle assembly 5 to switch between the positioning state and the avoidance state once. When the baffle assembly is in the positioning state, the parts on the baffle assembly 5 will be horizontally arranged on the side of the pigment box, forcing the pigment box to stop moving. When the pigment box is filled, the baffle assembly 5 will retract backwards to allow the pigment box to continue to be transported on the conveyor belt 3, and so on. This is better than the prior art. The filling of the entire pigment box adopts an automated structure setting, and during the filling process, the baffle assembly 5 will force the pigment box to be positioned below the discharge port 2, and continue to move after the pigment filling is completed, so as to avoid the pigment dripping out of the pigment box during the filling process.

[0029] On the basis of the above embodiment: the driving device 6 includes a driving motor 61 and a transmission gear set 7 linked to the driving motor 61, the transmission gear set 7 is linked with a cam 8, the blocking rod assembly 5 includes a positioning rod 51 and a transmission rod 52 for driving the positioning rod 51 to move, and the cam 8 can knock the transmission rod 52 to drive the positioning rod 51 to move toward the side close to the paint box.

[0030] The above specific improvements are: Figure 3 and Figure 5 As shown, the driving device 6 includes a driving motor 61 and a transmission gear set 7 linked to the driving motor 61, and the cam 8 is fixed on the transmission gear set 7. When the driving motor 61 rotates, it will drive the transmission gear set 7 to rotate, and the transmission gear set 7 will drive the cam 8 to rotate. The cam 8 hits the transmission rod 52, and the transmission rod 52 swings to drive the positioning rod 51 to move toward the side close to the paint box. Even if the conveyor belt 3 is still rotating, the paint box will stop moving due to the obstruction of the positioning rod 51.

[0031] On the basis of the above embodiment: a sliding assembly 9 is arranged between the positioning rod 51 and the transmission rod 52, and the sliding assembly 9 includes a slide rail 91 positioned on the frame 1 and a slider 92 slidably arranged above the slide rail 91, one end of the slider 92 is fixedly connected to the positioning rod 51, and the other end is swingably connected to the transmission rod 52, and the middle position of the transmission rod 52 is hinged to the frame 1. When the cam 8 hits one side of the transmission rod 52, the other side of the transmission rod 52 will drive the slider 92 to move laterally to drive the positioning rod 51 to move toward the side close to the paint box to position the paint box.

[0032] The above specific improvements are: Figure 2 , Figure 3 andFigure 5 As shown in the figure, the sliding assembly 9 includes a slide rail 91 and a slider 92 disposed above the slide rail 91. The slider 92 is fixed to one side of the positioning rod 51, and the slide rail 91 is fixed to the frame 1. When the rotating shaft of the driving motor 61 rotates one circle, the cam 8 will be driven to rotate one circle. The convex block on the cam 8 will strike the bottom of the transmission rod 52, causing the bottom of the transmission rod 52 to swing forward. The top of the transmission rod 52 will then swing, driving the slider 92 to move along the extension direction of the slide rail 91, causing the positioning rod 51 to move towards the side close to the paint box, thereby driving the positioning rod 51 to move and switching the blocking rod assembly 5 from the avoidance state to the positioning state.

[0033] Based on the above embodiment: The transmission gear set 7 includes a first transmission shaft 71 and a second transmission shaft 72. A first transmission chain 73 is provided between the first transmission shaft 71 and the rotating shaft of the driving motor 61. A second transmission chain 74 is provided between the first transmission shaft 71 and the second transmission shaft 72. The cam 8 is coaxially disposed on the second transmission shaft 72.

[0034] The above specific improvement is: As Figure 3 shown, when the driving motor 61 rotates one circle, due to the transmission of the first transmission chain 73, the first transmission shaft 71 is driven to rotate one circle. Due to the transmission of the second transmission chain 74, the first transmission shaft 71 drives the second transmission shaft 72 to rotate one circle, thereby driving the cam 8 to rotate one circle. The cam 8 strikes the transmission rod 52 once, driving the slider 92 to move once, so that the blocking rod assembly 5 switches from the avoidance state to the positioning state once. When the cam 8 continues to rotate, the convex block on the cam 8 separates from the transmission rod 52, and the transmission rod 52 resets due to its own reset function. At this time, the blocking rod assembly 5 switches from the positioning state to the avoidance state. When the cam 8 rotates one circle, it strikes the transmission rod 52 again, and the blocking rod assembly 5 continues to switch from the avoidance state to the positioning state.

[0035] Based on the above embodiment: The transmission gear set 7 further includes a third transmission shaft 75. A third transmission chain 76 is provided between the second transmission shaft 72 and the third transmission shaft 75. The conveyor belt 3 is driven by a driving wheel shaft 77. A fourth sprocket 78 is provided between the driving wheel shaft 77 and the third transmission shaft 75.

[0036] Based on the above embodiment: One end of the fourth sprocket 78 is sleeved on the driving wheel shaft 77, and the other end is sleeved on the side of the third transmission shaft 75 opposite to the third sprocket.

[0037] Based on the above embodiment: At least one driving gear 79 for driving the conveyor belt 3 to rotate is coaxially disposed at the driving wheel shaft 77.

[0038] The above specific improvement is: As Figure 3 and Figure 4As shown, the transmission gear set 7 also includes a third transmission shaft 75. When the second transmission shaft 72 rotates, the third transmission shaft 75 can be driven to rotate through the third transmission chain 76. The third transmission shaft 75 drives the driving wheel shaft 77 to rotate through the transmission of the fourth sprocket 78, thereby driving the conveyor belt 3 to rotate. When the shaft of the driving motor 61 rotates one circle, it will drive the first transmission shaft 71, the second transmission shaft 72, the third transmission shaft 75 and the driving wheel shaft 77 to rotate one circle respectively. The driving wheel shaft 77 drives the driving gear 79 to rotate one circle. The driving gear 79 rotates one circle just for the distance moved by the two bottles of paint boxes. Therefore, when the shaft of the driving motor 61 rotates one circle, every two bottles of paint boxes can pass through, and the blocking rod assembly 5 continues to switch from the avoidance state to the positioning state once, and so on.

[0039] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
