Description

Technical Field

[0001] The present invention relates to the technical field of jigs, and in particular to a flipping and clamping mechanism applied to a small straight lipstick machine. Background Art

[0002] Lipstick, as a kind of beauty cosmetic, has the functions of enhancing facial beauty and correcting lip contours. With the continuous improvement of people's living standards, it has almost become an essential beauty cosmetic for women. After the lipstick is formulated, it is generally filled into packaging containers according to a predetermined amount by a filling machine.

[0003] In the production process of lipstick, the raw materials for making the paste are melted and stirred → the molten paste is put into a mold for cooling and forming. After cooling and forming, the paste formed in the mold is taken out by packaging materials and stored to make lipstick; currently, in the process of loading the paste into the packaging materials, it is necessary to clamp the packaging materials by a flipping and clamping mechanism installed on a conveying mechanism, then perform a 180° flip, transfer it to the cooling and forming mold through the conveying mechanism, and then insert it into the mold of the cooled and formed paste so that the cooled and formed paste is loaded into the packaging materials. Immediately afterwards, the packaging materials filled with the paste are sent out through the conveying mechanism to make lipstick; the existing flipping and clamping mechanism mainly includes a pneumatic fixture, a fixture cylinder, a rotating mechanism and a main body. The flipping and clamping mechanism is positioned by the main body, the rotating mechanism is installed on the main body, the fixture cylinder is installed on the movable end of the rotating mechanism, and the pneumatic fixture is installed on the movable end of the fixture cylinder. The design of this structure has many deficiencies; firstly, the assembly compactness of each component of the flipping and clamping mechanism is not high, and the overall cooperation strength is low, so that the production of parts and their cooperation require more materials, resulting in a larger overall volume, larger floor area, cumbersome operation and high energy consumption of the flipping and clamping mechanism; secondly, when the rotating mechanism drives the fixture cylinder to rotate, the air pipe connecting the fixture cylinder will rotate simultaneously. In the long run, the service life of the air pipe will be reduced, and at the same time, air leakage will occur; thirdly, the rotating mechanism generally serves as the main body and will drive the fixture cylinder and the pneumatic fixture to rotate simultaneously, which will bring a greater load to the rotating mechanism and reduce the service life of the flipping and clamping mechanism; therefore, it is necessary to propose an improved technical solution to solve the above problems.

Specific embodiments

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0026] Please refer to Figures 1-3, in an embodiment of the present invention, a flipping and clamping mechanism applied to a small linear lipstick machine includes a bearing seat 10, a power component 20, an air path rotating shaft 30, an air path adapter valve body 40, a pneumatic component 50, and a clamping claw 60. The power component 20 is fixedly installed at one end of the bearing seat 10. The air path rotating shaft 30 is movably disposed through the bearing seat 10, and one end of the air path rotating shaft 30 is in power connection with the power component 20. The other end of the air path rotating shaft 30 is fixedly connected to the air path adapter valve body 40. The pneumatic component 50 is fixedly connected to the air path adapter valve body 40. The clamping claw 60 is in power connection with the pneumatic component 50. An air inlet passage 31 and an air exhaust passage 32 are provided in the air path rotating shaft 30. An air inlet transition passage 41 communicating with the air inlet passage 31 and an air exhaust transition passage 42 communicating with the air exhaust passage 32 are provided in the air path adapter valve body 40. The air inlet transition passage 41 is connected to the air inlet end of the pneumatic component, and the air exhaust transition passage 42 is connected to the air outlet end of the pneumatic component. An air inlet groove 33 communicating with the air inlet passage 31 and an air exhaust groove 34 communicating with the air exhaust passage 32 are circumferentially provided on the outer wall of the air path rotating shaft 30. The air inlet groove 33 and the air exhaust groove 34 are respectively in sealing cooperation with the inner wall of the bearing seat 10, and two air pipe joints 11 communicating with the air inlet groove 33 and the air exhaust groove 34 are provided on the bearing seat 10.

[0027] In the above technical solution, a flipping and clamping mechanism is composed of a bearing seat 10, a power component 20, a gas path rotating shaft 30, a gas path adapter valve body 40, a pneumatic component 50, and a clamping jaw 60. Among them, for the flipping operation, the power component 20 provides power to drive the gas path rotating shaft 30 to rotate, and then the gas path rotating shaft 30 drives the clamping jaw 60 connected to the gas path adapter valve body 40 to rotate, so as to drive the processed product on the clamping jaw 60 to flip; for the clamping operation, an air inlet passage 31 and an exhaust passage 32 are arranged on the gas path rotating shaft 30, and an air inlet groove 33 and an exhaust groove 34 communicating with the two are arranged on the outer side of the gas path rotating shaft 30. The air inlet groove 33 and the exhaust groove 34 are hermetically matched with the inner wall of the bearing seat 10 respectively. The bearing seat 10 is connected to the air inlet end and the air outlet end of the air pump through two air pipe joints 11 respectively. The air pump supplies compressed gas, and the compressed gas enters the air inlet groove 33 along the air pipe joint 11, then enters the air inlet passage 31 from the air inlet groove 33, and then is supplied to the pneumatic component 50 along the air inlet transition passage 41, so that the pneumatic component 50 generates power to drive the clamping jaw 60 to clamp the processed product; through the above technical means, the structures for driving the clamping jaw 60 to flip and driving the clamping jaw 60 to perform a clamping action are optimized, so that the compactness of each component of the flipping and clamping mechanism is improved, the overall matching strength can be greatly improved, the overall volume can be made smaller, the floor area is reduced, and the operation smoothness is improved; the cooperation between the bearing seat 10 and the gas path rotating shaft 30 can replace the structure that drives the air pipe to twist in the traditional flipping action, greatly improving the service life of the flipping and clamping mechanism; in addition, through the rotational cooperation between the bearing seat 10 and the pneumatic rotating shaft, and the bearing seat 10 is connected to the conveying mechanism as a fixed end, the bearing capacity of the power component 20 can be reduced, so that the power component 20 operates more smoothly, further improving the service life of the flipping and clamping structure.

[0028] Furthermore, as Figures 1-2As shown in the figure, the pneumatic component 50 includes a jig docking plate 51 fixedly connected to the air path adapter valve body 40 and two pneumatic actuators 52 respectively installed at the front and rear positions of the jig docking plate 51. The clamping claws 60 are two slats that can be tensioned and fitted. The two slats are power-connected between the two pneumatic actuators 52. Among them, the jig docking plate 51 is designed to fix the two pneumatic actuators 52 (the pneumatic actuators 52 are preferably clamping cylinders). At the same time, the jig docking plate 51 is designed according to the jig structure for positioning the packaging material. In the operation of frequently grasping the packaging material to fill the paste, through the positioning cooperation between the jig docking plate 51 and the jig for positioning the packaging material, and then clamping the packaging material through the clamping claws 60, the packaging material can be clamped more accurately. In addition, the clamping claws 60 are set as two slats that can be tensioned and fitted. A round opening for sleeving the packaging material is provided between the two slats. After the two slats are closed, the packaging material will be clamped. By using the two pneumatic actuators 52 to be respectively power-connected to the two ends of the slats, the firmness of the tensioning and fitting of the slats can be greatly improved, so that the clamping claws 60 can clamp the packaging material more stably.

[0029] Further, as Figures 2-3 shown, the air path connection between the pneumatic actuator 52 and the air path adapter valve body 40 is such that branch channels 43 are respectively provided in the intake transition channel 41 and the exhaust transition channel 42. Two intake outlets 45 are provided in the intake transition channel 41 through the branch channels 43, and two exhaust inlets 44 are provided in the exhaust transition channel 42 through the branch channels 43. The two intake outlets 45 are respectively connected to the intake ends of the two pneumatic actuators 52, and the two exhaust inlets 44 are respectively connected to the outlet ends of the two pneumatic actuators 52. In order to improve the compactness of the structural cooperation between the pneumatic component 50 and the air path adapter valve body 40, the two pneumatic actuators 52 can also be arranged such that one pneumatic actuator 52 is close to the air path adapter valve body 40, and the other pneumatic actuator 52 is far from the air path adapter valve body 40. Then the pneumatic actuator close to the air path adapter valve body 40 is directly connected to the air path adapter valve body 40 without tracheal transition, while the pneumatic actuator far from the air path adapter valve body 40 is directly connected to the air path adapter valve body 40 through a trachea, so that the tracheal layout on the pneumatic component 50 can be more streamlined.

[0032] Further, as Figure 3 shown, in order to achieve the firmness and sealing performance of the connection between the air path rotating shaft 30 and the air path adapter valve body 40, the front end of the air path rotating shaft 30 is of a polygonal structure, a rotating shaft connection groove 46 matching the front end of the air path rotating shaft 30 is provided at the rear part of the air path adapter valve body 40, the front end of the air path rotating shaft 30 is connected to the rotating shaft connection groove 46, the intake transition passage 41 and the exhaust transition passage 42 are both arranged at the bottom of the rotating shaft connection groove 46, and second sealing rings 47 corresponding to the intake passage 31 and the exhaust passage 32 are respectively provided at the front end of the air path rotating shaft 30.
