Description

Technical Field

[0001] This utility model belongs to the field of cosmetic production technology, and in particular relates to a clamping and flipping mechanism for cosmetic plastic boxes. Background Technology

[0002] In the processing and production of cosmetics, the production date and product information need to be printed onto the outer packaging plastic boxes. To ensure the information is printed in the designated area, the plastic boxes often need to be flipped and repositioned so that the side with the printing area faces the printing device. However, currently, most cosmetic plastic box printing processes still require manual operation, involving manually flipping the boxes for repositioning. This not only results in low flipping accuracy but also increases the workload for workers and is inefficient. Therefore, there is an urgent need to provide a cosmetic plastic box clamping and flipping mechanism that enables mechanized operation. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing a cosmetic plastic box clamping and flipping mechanism that is reasonably designed, simple in structure, and capable of mechanized operation, thereby solving the problems existing in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A cosmetic plastic box clamping and flipping mechanism includes an upper box and clamping components. A lower box is mounted on the outer side of the bottom of the upper box with a bearing. Two sliding grooves are symmetrically formed inside the bottom of the lower box. Limit rods are fixed to the inner sides of the two sliding grooves. Clamping components are slidably mounted on the outer sides of the limit rods. A stepper motor is fixedly installed at the center of the inner wall of the top of the upper box. A vertical shaft is fixedly connected to the output end of the stepper motor. The bottom end of the vertical shaft is fixedly connected to the inner bottom surface of the lower box. A control mechanism is mounted on the outer side of the vertical shaft. Electric push rods are symmetrically arranged on both sides of the stepper motor. The fixed end of the electric push rod is fixedly connected to the upper box, and the telescopic end of the electric push rod is fixedly connected to a mounting plate. The mounting plate is mounted on the outer side of the top of the control mechanism. The two sets of clamping components are linked by the control mechanism and their sliding directions are always opposite.

[0006] Preferably, the control mechanism includes a vertical tube, a flat plate, and a guide groove. The vertical tube is engaged and slidably sleeved on the outside of the vertical shaft. The vertical tube is movably connected to the upper box body. A flat plate is fixedly installed on the bottom outer wall of the vertical tube. Guide grooves are opened inside both the left and right ends of the flat plate.

[0007] Preferably, the mounting plate bearing is sleeved on the outer side of the top end of the vertical pipe.

[0008] As a preferred option, the two guide slots are arranged in a figure-eight shape.

[0009] Preferably, the clamping assembly includes a clamping rod, an extension post, and an anti-slip pad. The clamping rod has an "L"-shaped longitudinal section, with its vertical section engaging and sliding within a groove and slidingly sleeved on the outside of a limiting rod. An extension post is fixedly installed on the top outer wall of the clamping rod, and an anti-slip pad is adhered to the bottom horizontal section of the clamping rod.

[0010] Preferably, the end of the extension column opposite to the clamping rod is guided and slidably connected to the guide groove provided in the control mechanism.

[0011] Preferably, the anti-slip mat is made of elastic rubber.

[0012] Preferably, the surface of the anti-slip pad facing away from the clamping rod is roughened.

[0013] Preferably, the outer wall of the vertical axis has symmetrical protrusions of equal length.

[0014] Preferably, the two sets of clamping components are arranged symmetrically about the lower housing.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In this invention, the device can be mounted on a robotic arm and the two clamping rods can be positioned on either side of the plastic box to be flipped. Then, the electric push rod is activated to control the mounting plate to move the control mechanism down synchronously. The guide grooves inside both ends of the plate can simultaneously squeeze the two extension columns, so that the two clamping rods can be controlled to slide synchronously along the limit rod and move closer to each other, which is convenient for clamping plastic boxes of various sizes. In addition, the bottom of the clamping rods is also glued with rubber anti-slip pads, which can enhance the clamping stability.

[0017] This invention enables the vertical shaft, control mechanism, lower housing, and two sets of clamping components to rotate synchronously by starting a stepper motor, thus facilitating precise flipping of the clamped plastic box. This device adopts mechanized operation, which can replace the traditional manual flipping operation, thereby reducing labor intensity and improving production efficiency.

A clamping assembly 5 is slidably mounted on the outer side of the limit rod 4. A stepper motor 6 is fixedly installed at the center of the inner wall of the top of the upper box 1. A vertical shaft 7 is fixedly connected to the output end of the stepper motor 6. The bottom end of the vertical shaft 7 is fixedly connected to the inner bottom end face of the lower box 2. A control mechanism 8 is mounted on the outer side of the vertical shaft 7. Electric push rods 9 are symmetrically arranged on both sides of the stepper motor 6. The fixed end of the electric push rod 9 is fixedly connected to the upper box 1. The telescopic end of the electric push rod 9 is fixedly connected to the mounting plate 10. The mounting plate 10 is mounted on the outer side of the top of the control mechanism 8. The two sets of clamping assemblies 5 are linked by the control mechanism 8 and their sliding directions are always opposite.

[0027] As a preferred embodiment, based on the above structure, preferably, the two sets of clamping components 5 are arranged symmetrically about the lower housing 2.

[0028] In this embodiment, the control mechanism 8 facilitates the linkage of the two sets of clamping components 5.

[0029] As a preferred embodiment, based on the above structure, the clamping assembly 5 preferably includes a clamping rod 51, an extension post 52, and an anti-slip pad 53. The clamping rod 51 has an "L"-shaped longitudinal section, and its vertical section is engaged and slidably located in the slide groove 3 and slidably sleeved on the outside of the limiting rod 4. The extension post 52 is fixedly installed on the top outer wall of the clamping rod 51, and the anti-slip pad 53 is adhered to the bottom horizontal section of the clamping rod 51.

[0030] As a preferred embodiment, based on the above structure, preferably, the anti-slip pad 53 is made of elastic rubber, and the surface of the anti-slip pad 53 facing away from the clamping rod 51 is roughened.

[0031] In this embodiment, by controlling the two clamping rods 51 to slide synchronously along the limiting rod 4 and move closer to each other, it is convenient to clamp the plastic box, and the use of the rubber anti-slip pad 53 helps to enhance the clamping stability.

[0032] As a preferred embodiment, based on the above structure, preferably, the outer wall of the vertical axis 7 is provided with symmetrical protrusions of equal length.

[0033] In this embodiment, the symmetrically arranged protrusions on the outer wall of the vertical shaft 7 facilitate the synchronous rotation of the control mechanism 8 driven by the vertical shaft 7.

[0034] As a preferred embodiment, based on the above structure, the control mechanism 8 preferably includes a vertical tube 81, a flat plate 82 and a guide groove 83. The vertical tube 81 is engaged and slidably sleeved on the outside of the vertical shaft 7. The vertical tube 81 is movably connected to the upper box 1. The flat plate 82 is fixedly installed on the bottom outer wall of the vertical tube 81. Guide grooves 83 are opened inside both the left and right ends of the flat plate 82.

[0039] The working principle of this utility model is as follows:

[0040] When in use, the device can first be installed on the robotic arm. When the cosmetic plastic box needs to be flipped during the process of being transported through the assembly line, the device can be moved and the two clamping rods 51 are respectively located on both sides of the plastic box to be flipped. Then, the electric push rod 9 fixedly installed in the upper box 1 is activated to control the mounting plate 10 to drive the control mechanism 8 to move down synchronously. The guide grooves 83 opened inside both ends of the plate 82 can be used to simultaneously squeeze the two extension columns 52, which makes it easy to control the two clamping rods 51 to slide synchronously along the limit rod 4 and move closer to each other. Moreover, the bottom of the clamping rods 51 is also glued with rubber anti-slip pads 53, which makes it easy to stably clamp plastic boxes of various sizes.

[0041] After the plastic box is clamped and stabilized, the stepper motor 6 can be started to control the vertical shaft 7 to drive the control mechanism 8, the lower box 2 and the two sets of clamping components 5 to rotate synchronously, so as to facilitate the precise flipping of the clamped plastic box. This device adopts mechanized operation, which can reduce the workload and increase efficiency.

[0042] It should be noted that the stepper motor 6 and electric push rod 9 used in this device are existing electrical products, powered by an external power source and electrically connected to an external controller via connecting wires. The specific control methods are mature technologies and will not be described in detail here.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model.
