DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Reference Figure 1-Figure 5 A positioning device for processing a lipstick tube comprises a ring-shaped lipstick tube body 1 and a processing platform 2 for processing the lipstick tube body. Conveyor belts 3 for conveying materials are diagonally arranged on both sides of the processing platform 2. Telescopic rods 4 are symmetrically distributed and fixedly connected to the upper surface of the processing platform 2. A push cylinder 5 is fixedly connected to one side surface of the telescopic rod 4. The piston rod surface of the push cylinder 5 is fixedly connected to the telescopic end surface of the telescopic rod 4. An external positioning mechanism 6 is arranged on the upper middle surface of the processing platform 2, and an internal clamping mechanism 7 is arranged between the two telescopic rods 4.

[0030] The lipstick tube body 1 is placed in the external positioning mechanism 6, and the external positioning mechanism 6 is rotated in a circular manner to position and clamp the outer surface of the lower end base of the lipstick tube body 1.

[0031] In order to position and clamp the lipstick tube 1 and facilitate polishing of its outer surface, the lipstick tube 1 is placed on the inner surface of the positioning ring 61, and the external positioning mechanism 6 includes a positioning ring 61 fixedly connected to the upper surface of the middle part of the processing platform 2, and the upper surface of the positioning ring 61 is provided with adjustment grooves 62 distributed in a ring array, and the inner surface of the adjustment groove 62 is slidably engaged with a T-shaped clamping and positioning block 63, and the arc surface of the clamping and positioning block 63 is in sliding contact with the outer surface of the lower end base of the lipstick tube 1. Multiple clamping and positioning blocks 63 are synchronously extended and retracted inside the adjusting groove 62 to achieve their clamping effect, and the contact surface material of the positioning clamping block and the lipstick tube body 1 is rubber, thereby preventing positioning deviation and clamping the lipstick tube body 1 without damage.

[0032] In order to drive the clamping and positioning block 63 to perform telescopic adjustment and realize its clamping and positioning function, the external positioning mechanism 6 also includes an adjusting ring 64 rotatably connected to the upper surface of the positioning ring 61 through a bearing. The upper surface of the adjusting ring 64 is distributed in a circular array and is penetrated by obliquely distributed track grooves 65. The upper surface of the clamping and positioning block 63 is fixedly connected with a driving rod 66. The driving rod 66 penetrates the track groove 65 and is slidably connected to its inner surface. By driving the adjusting ring 64 to rotate, the driving rod 66 can be pulled to move inside the track groove 65, thereby driving the positioning clamping block inside the adjusting slide groove 62 to perform telescopic adjustment, so that it can contact and clamp the outer surface of the base at the lower end of the lipstick tube body 1.

[0033] In order to drive the adjusting ring 64 to rotate and adjust, the external positioning mechanism 6 also includes a connecting groove 67 opened on the surface of one end of the adjusting ring 64. A mounting block 68 is fixedly connected to the outer surface of one side of the positioning ring 61. A pushing cylinder 69 is hinged on the surface of one side of the mounting block 68. The piston rod surface of the pushing cylinder 69 is hinged to the inner surface of the connecting groove 67. By moving the pushing cylinder 69, the piston rod pushes the adjusting ring 64 to rotate a certain angle, which can pull the positioning clamping block to extend and retract, so that it pushes the lipstick tube body 1 and the center of the positioning ring 61 to remain on the same vertical line.

[0034] By setting up the external positioning mechanism 6, the outside of the lipstick tube 1 of different sizes can be positioned and clamped. During the adjustment process, by placing the lipstick tube 1 on the inner surface of the positioning ring 61, the pushing cylinder 69 is activated so that its piston rod pushes the adjustment ring 64 to rotate a certain angle, which can then pull the driving rod 66 to move inside the track groove 65, thereby driving the positioning clamping block inside the adjustment slide groove 62 to perform telescopic adjustment, so that it can contact and clamp the outer surface of the lower end base of the lipstick tube 1 without damage.

[0035] The internal clamping mechanism 7 extends into the paste tube of the lipstick tube body 1 after being lifted and lowered, and performs material transfer after clamping it.

[0036] In order to support the processed part of the lipstick tube 1 under force, the internal clamping mechanism 7 includes a self-driving slide rail 71 fixedly connected to the surface of the opposite side of the two telescopic rods 4, the outer surface of the self-driving slide rail 71 is slidably clamped with a supporting slider 72, and the lower surface of the supporting slider 72 is fixedly connected with a connecting rod 73 extending into the interior of the lipstick tube 1. The self-driving slide rail 71 drives the internal screw rod to rotate through its motor to make the supporting slider 72 move horizontally to the top of the lipstick tube 1. As the push cylinder 5 is activated, the connecting rod 73 can be extended into the interior of the lipstick tube 1 to realize the internal clamping action, thereby stabilizing the main body of the lipstick tube 1.

[0037] In order to clamp and connect the inner surface of the lipstick tube body 1, the external positioning mechanism 6 is cooperated to realize the positioning and clamping of the lipstick tube body 1, and to facilitate the subsequent material shifting and adjustment, so that the internal clamping mechanism 7 also includes micro cylinders 74 distributed in an annular array and fixedly connected to the outer surface of the lower end of the connecting rod 73, and the piston rod surfaces of the multiple micro cylinders 74 are hinged with rubber rings 75, and the outer surface of the rubber ring 75 is in sliding contact with the inner surface of the lipstick tube body 1. After the connecting rod 73 is extended into the lipstick tube body 1, the micro cylinder 74 is actuated to cause its piston rod to push the rubber ring 75 to expand its diameter until it is tightly pressed against the inner surface of the lipstick tube body 1, thereby realizing the connection between the lipstick tube body 1 and the connecting rod 73.

[0038] By setting up the internal clamping mechanism 7, the inner surface of the lipstick tube body 1 can be clamped, so that the internal and external forces of the lipstick tube body 1 are balanced during processing. In the process of adjustment, the micro cylinder 74 is actuated to cause its piston rod to push the rubber ring 75 to expand its diameter until it is tightly pressed against the inner surface of the lipstick tube body 1, thereby realizing the connection between the lipstick tube body 1 and the connecting rod 73, and the material transfer of the lipstick tube body 1 is realized by the action of the self-driving slide rail 71.

[0039] Working principle: In a specific embodiment of the utility model, the lipstick tube body 1 is placed on the inner surface of the positioning ring 61, and then the inner surface of the mounting block 68 is used to adjust the cylinder so that the piston rod pushes the adjusting ring 64 to rotate a certain angle, and then the driving rod 66 can be pulled to move inside the track groove 65, thereby driving the positioning clamping block inside the adjusting slide groove 62 to perform telescopic adjustment, so that it can contact and clamp the outer surface of the base at the lower end of the lipstick tube body 1;

[0040] Then, the self-driving slide rail 71 drives the internal screw to rotate through its motor, so that the supporting slide block 72 moves horizontally to the top of the lipstick tube body 1. As the push cylinder 5 moves, the connecting rod 73 can be extended into the inside of the lipstick tube body 1. Through the action of the micro cylinder 74, its piston rod pushes the rubber ring 75 to expand its diameter until it is tightly against the inner surface of the lipstick tube body 1.

[0041] After the internal and external positioning, the outer surface of the lipstick tube body 1 is processed, and after the processing is completed, the external positioning mechanism 6 is relaxed, and then the lipstick tube body 1 can be moved to the upper surface of the conveyor belt 3 and transported to the next station through the action of the push cylinder 5 and the self-driving slide rail 71.
