[0022] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0023] Embodiment 1:
[0024] like Figure 1 As shown, this embodiment discloses a stamping fixture for stamping a three-dimensional logo on the top surface of a lipstick tube shell 5. The stamping fixture includes a top press 1, a bottom plate 2, two clamping devices 3 installed on the upper end surface of the bottom plate 2, and a lower die 4. A placement space 21 is formed between the two clamping devices 3. The lower die 4 is fixedly installed on the upper end surface of the bottom plate 2. The lower die 4 is located in the placement space 21. The top press 1 includes an upper die 13. The upper die 13 corresponds to the position of the lower die 4. The lower die 4 can place the lipstick tube shell 5. The lower die 4 is cylindrical. The lipstick tube shell 5 can be mounted on the lower die 4. The upper die 13 is pressed down by a punching machine to press the upper die 13 onto the lower die 4, thereby forming a three-dimensional logo on the top of the lipstick tube shell 5.
[0025] More preferably, the top press 1 includes a second press block 12, the second press block 12 is located on the lower end surface of the top press 1, the second press block 12 is located at the center of the top press 1, the upper press die 13 is fixedly installed on the lower end of the second press block 12, the upper press die 13 and the second press block 12 are detachably installed, and the lower press die 4 and the base plate 2 are detachably installed, and can be replaced according to the needs of stamping the lipstick tube shell 5 and different logos.
[0026] like Figure 1 As shown, the clamping device 3 includes a shell 31, a first movable member 34, and a clamping block 38. The shell 31 is provided with a first channel 32 and a second channel 33. The shell 31 is fixedly mounted on the upper end surface of the base plate 2. The first channel 32 and the second channel 33 are vertically arranged. The first channel 32 is vertically arranged, and the second channel 33 is horizontally arranged. The first movable member 34 can move along the first channel 32, and a part of the first movable member 34 extends upward beyond the first channel 32. The top press 1 includes a first pressing block 11. The first pressing block 11 is located at the lower end surface of the top press 1. The first pressing block 11 abuts against the upper end of the first movable member 34. The downward pressing of the first pressing block 11 can drive the first movable member 34 to move downward along the first channel 32. The downward movement of the first movable member 34 can drive the clamping block 38 to move toward the lower die 4.
[0027] More preferably, the first movable member 34 is provided with a guide ring 341, and a first spring 321 is installed in the first channel 32. The first spring 321 abuts against the lower end surface of the guide ring 341. The first spring 321 is used to restore the first movable member 34 upward when the pressure top 1 is restored, so that the upper end of the first movable member 34 abuts against the first pressure block 11, and when the first movable member 34 reaches the highest position, the upper end surface of the guide ring 341 does not exceed the first channel 32.
[0028] like Figure 1 , Figure 2As shown, a second movable member 35 and a second spring 36 are installed in the second channel 33, and the two ends of the second spring 36 abut against the second movable member 35 and the clamping block 38. The second movable member 35 is provided with an inclined surface 351, and the lower end of the first movable member 34 abuts against the inclined surface 351 of the second movable member 35. The lower end of the first movable member 34 is hemispherical. When the first movable member 34 moves downward, the inclined surface 351 of the second movable member 35 is pressed by the first movable member 34, so that the second movable member 35 moves in a direction away from the first movable member 34, so that the second movable member 35 compresses the second spring 36, and then pushes the clamping block 38 to move. Since the force of the top pressing 1 is relatively large when it descends, the first spring 321 and the second spring 36 can reduce the force of the first movable member 34 and the second movable member 35 respectively, so as to prevent the clamping force of the clamping block 38 on the lipstick tube shell 5 from being too large, causing deformation and wear of the lipstick tube shell 5.
[0029] The clamp block 38 can move along the second channel 33. The second channel 33 includes a third channel 37. The third channel 37 is located at one end of the second channel 33 close to the lower die 4. At least a part of the clamp block 38 is located in the third channel 37. A third spring 39 is installed in the third channel 37. The clamp block 38 includes a limit ring 381. The third spring 39 resists the limit ring 381 and exerts a force on the clamp block 38 away from the lower die 4. When the clamp block 38 is subjected to the pressure of the second spring 36, the clamp block 38 overcomes the third spring 39, so that the clamp block 38 is close to the lower die 4, so that the clamping block 38 can press against the side wall of the lipstick tube shell 5 located on the lower die 4 to clamp it. When the pressing top 1 is pressed down, the first pressing block 11 first presses the first movable member 34 downward, so that the clamping block 38 clamps the lipstick tube shell 5 before the upper die 13 punches the lipstick tube shell 5, so that the upper die 13 is more stable when punching the lipstick tube shell 5. When the upper die 13 returns upward, the clamping block 38 can still clamp the lipstick tube shell 5 for a certain time due to the action of the second spring 36, so as to prevent the upper die 13 from lifting the lipstick tube shell 5 upward.
[0030] More preferably, the clamping block 38 includes a soft rubber block 382, which is located at one end of the clamping block 38 facing the lower die 4. The soft rubber block 382 can reduce the clamping impact of the clamping block 38 on the lipstick tube shell 5, and can cover and clamp the side wall of the lipstick tube shell 5 to prevent the lipstick tube shell 5 from deforming. The end face of the clamping block 38 facing the lower die 4 is arc-shaped, and the arc-shaped end face can better fit the side wall of the lipstick tube shell 5.
[0031] like Figure 1 , Figure 2 As shown, the clamp block 38 includes an initial state and a final state. Figure 1The initial state is that the top press 1 is at the highest point, the first movable member 34 is at the highest position, and the clamping block 38 is at a position away from the lower die 4. From the initial state to the final state, the top press 1 is pressed downward to make the first movable member 34 move downward, which can drive the clamping block 38 to move toward the lower die 4. Figure 2 It is a schematic diagram of the final state. In the final state, the pressing top 1 is located at the lowest point, the upper pressing die 13 contacts the upper end surface of the lipstick tube shell 5, and the clamping block 38 abuts against the side wall of the lipstick tube shell 5.
[0032] Embodiment 2:

The feeding device 6 includes a first guide rail 61 and a first feeding suction cup 62. The first feeding suction cup 62 feeds the lipstick tube shell 5 in the feeding box 63 to the adjusting device 7. The adjusting device 7 is used to adjust the direction of the lipstick tube shell 5. The adjusting device 7 includes a placement rack 71. The placement rack 71 can rotate. If the side wall of the lipstick tube shell 5 is also provided with There is a logo, and the adjustment device 7 can adjust all the lipstick tube shells 5 to a unified direction before loading, so that the logo on the side wall of the lipstick tube shell 5 corresponds to the logo on the top of the lipstick tube shell 5, making the lipstick tube shell 5 more beautiful. The transfer device 8 includes a second loading suction cup 82 and a unloading clamp 83. The second loading suction cup 82 can transfer the lipstick tube shell 5 on the adjustment device 7 to the stamping fixture, and the unloading clamp 83 can transfer the lipstick tube shell 5 on the stamping fixture to the collection box 9.
[0034] More preferably, the placement rack 71 and the lower die 4 are located in the same straight line, the distance between the second loading suction cup 82 and the unloading clamp 83 is the same as the distance between the placement rack 71 and the lower die 4, the second loading suction cup 82 and the unloading clamp 83 can move along the second guide rail 81 at the same time, and when the second loading suction cup 82 sucks the lipstick tube shell 5 on the placement rack 71, the unloading clamp 83 clamps the lipstick tube shell 5 stamped on the lower die 4, and when the second loading suction cup 82 places the lipstick tube shell 5 on the lower die 4, the unloading clamp 83 places the lipstick tube shell 5 into the collection box 9.
[0035] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of the utility model belong to the protection scope of the utility model.
