A pressure ring mechanism for filling air cushion foundation

Abstract

The present invention relates to a pressing ring mechanism for filling an air cushion foundation, comprising a bracket, a pressing head assembly and a driving assembly. The pressing head assembly comprises a mounting seat, a pressing head and a connecting piece. The connecting piece is configured so that the pressing head has a first working state and a second working state. When the pressing head is in the first working state, the abutting surface of the pressing head has a first abutting area located at a first height and a second abutting area located at a second height, so that the abutting surface can first partially abut on a plastic sealing ring, so that one side of the plastic sealing ring is first pressed together with the air cushion box, and the gas is allowed to be discharged between the other side and the air cushion box; when the pressing head is in the second working state, the abutting surface of the pressing head is a plane parallel to the horizontal plane, so that the plastic sealing ring and the air cushion box can be completely pressed together. Since the excess gas between the plastic sealing ring and the air cushion box has been discharged, no bulge will be generated after the plastic sealing ring is completely pressed together.

Description

Technical Field

[0001] The invention relates to the technical field of air cushion foundation filling equipment, and in particular to a pressure ring mechanism for filling air cushion foundation. Background Art

[0002] Air cushion foundation is a portable makeup product with advantages such as lightness, breathability and ease of use, and is increasingly favored by consumers. At present, the filling method of air cushion foundation mainly includes: placing a sponge into an opened air cushion box, and then using a filling head to fill the sponge with foundation liquid, tapping the sponge after filling to make the foundation liquid cover the entire sponge, and finally placing a plastic sealing ring (including the ring body and the plastic sealing film covering the ring body) on the air cushion box, pressing the plastic sealing ring onto the air cushion box through a ring pressing mechanism, and then closing the cover through a cover closing mechanism.

[0003] The existing pressing ring mechanism is mostly composed of a pressing head and a pressing head driving member, see patents CN 119305786 A, CN206494152 U, etc. The pressing head driving member drives the pressing head to press the plastic sealing ring vertically downward, so as to press the plastic sealing ring onto the air cushion box. However, the applicant has found in practice that when this type of pressing ring mechanism presses the plastic sealing ring vertically downward, it is easy to cause the plastic sealing film in the center of the plastic sealing ring to bulge, which affects the subsequent closing of the lid. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a novel pressure ring mechanism for filling air cushion foundation.

[0005] In order to achieve the above object, the technical solution adopted by the present invention is:

[0006] A pressing ring mechanism for filling an air cushion foundation comprises a bracket, a pressing head assembly and a driving assembly mounted on the bracket and used to drive the pressing head assembly to move in an up and down direction, the pressing head assembly comprises a mounting seat, a pressing head adapted to a plastic sealing ring of an air cushion foundation box and a connecting piece arranged between the mounting seat and the pressing head, the connecting piece being configured to enable the pressing head to have a first working state and a second working state, when the pressing head is in the first working state, an abutting surface of the pressing head has a first abutting area located at a first height and a second abutting area located at a second height, the first height being smaller than the second height; when the pressing head is in the second working state, the abutting surface of the pressing head is a plane parallel to a horizontal plane.

[0007] The applicant found that: when the existing pressure head mechanism is pressing the plastic sealing ring, the abutting surface of the pressure head is pressed on the plastic sealing ring, which makes it impossible for the excess air between the plastic sealing ring and the air cushion box to be discharged, which will cause the plastic sealing film in the center to bulge after the plastic sealing ring and the air cushion box are pressed together, affecting the subsequent closing of the cover on the air cushion box. The applicant designed the pressure head assembly so that the pressure head has two working states. When the pressure head is in the first working state, the abutting surface of the pressure head can first partially abut on the plastic sealing ring, so that one side of the plastic sealing ring is first pressed together with the air cushion box, and the other side is not pressed together with the air cushion box, so that a gap is formed between the two to allow air to pass through, and the excess air can pass through the gap. Then, the pressure head is switched to the second working state, and the plastic sealing ring and the air cushion box can be completely pressed together. Since the excess air has been discharged, no bulging will occur after the plastic sealing ring is completely pressed together.

[0008] In some embodiments, the pressure head includes multiple independent parts, at least one of the multiple parts is connected to the connecting member and can move in the up and down direction under the drive of the connecting member, and the remaining parts of the multiple parts are fixedly connected to the mounting seat and their abutting surfaces are located in the same horizontal plane. By designing the pressure head into petals, controllable adjustment of different areas is facilitated, and flexibility is better.

[0009] Preferably, the part of the multiple parts connected to the connecting piece is the first part, and the remaining parts of the multiple parts are the second parts. There is one first part and one second part. The first part is arcuate and its arc length is less than or equal to 1 / 2 of the circumference of the pressure head.

[0010] Further preferably, the second portion is arcuate.

[0011] Further preferably, the first part and the second part are symmetrically arranged along the vertical direction.

[0012] Preferably, the connecting member is a telescopic cylinder.

[0013] In some embodiments, the connecting member has a movable joint and an elastic part, the movable joint is mounted on the mounting seat, and the pressure head is fixedly connected to the movable joint; the elastic part abuts between the pressure head and the mounting seat, and makes the pressure head have an initial state of tilting downward. The design of the movable joint and the elastic part is simple in structure and low in cost.

[0014] Preferably, the movable joint comprises a sleeve fixedly connected to a mounting seat and a sphere movably disposed in the sleeve, the sphere and the sleeve form a rotatable fit, and the pressure head is mounted on the sphere.

[0015] Preferably, the elastic part is a spring.

[0016] Preferably, the elastic portion is located outside the rotation center line of the pressing head.

[0017] Preferably, the inclination angle of the pressure head in the initial state is 2°~10°, more preferably 3°~6°, and further preferably 4°~5°.

[0018] Preferably, the pressure head assembly further includes a pressure sensor mounted on the mounting seat. The pressure sensor is used to measure the pressing pressure of the pressure head, and the downward pressure of the pressure head is adjusted by the pressure feedback from the pressure sensor, so as to avoid damage to the air cushion box and the plastic sealing ring due to excessive pressing force, and to avoid incomplete pressing of the air cushion box and the plastic sealing ring due to insufficient pressing force.

[0019] Preferably, the pressure head assembly has multiple groups arranged at intervals, and the multiple groups of pressure head assemblies are connected by a connecting plate and move synchronously under the drive of the driving assembly. The design of multiple groups of pressure head assemblies has higher efficiency.

[0020] Preferably, the pressure head assembly further comprises a motor connected to the mounting seat and used for driving the mounting seat to move in an up-and-down direction.

[0021] Further preferably, the output shaft of the motor is threadedly connected to the mounting seat.

[0022] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0023] The present invention designs the pressure head assembly so that the pressure head has two working states. When the plastic sealing ring is pressed together, the pressure head is first in the first working state, and the abutting surface on the pressure head can first partially abut on the plastic sealing ring, so that one side of the plastic sealing ring is first pressed together with the air cushion box, and a gap is formed between the other side and the air cushion box to allow gas to pass through, so that excess air between the two is discharged through the gap, and then the pressure head is switched to the second working state, so that the plastic sealing ring and the air cushion box can be completely pressed together. Since the excess air between the plastic sealing ring and the air cushion box has been discharged, no bulging will occur after the plastic sealing ring is completely pressed together.

As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the embodiments of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0041] In the embodiments of the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes the first feature being directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature.

[0042] The disclosure below provides many different embodiments or examples to implement different structures of the embodiments of the present invention. In order to simplify the disclosure of the embodiments of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the embodiments of the present invention. In addition, the embodiments of the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0043] If not otherwise specified, the air cushion box described below is an air cushion liner, which usually includes an air cushion box body, a cover body hinged on the air cushion box body, a sponge accommodated in the air cushion box body and covered with liquid foundation, and a plastic sealing ring pressed on the air cushion box body, the plastic sealing ring including a ring body and a plastic sealing film covering the ring body.

[0044] The applicant previously developed a fully automatic air cushion foundation filling device (see patent CN 119305786 A). It was found during use that the device sometimes failed to close the lid, that is, the lid of the air cushion box could not be closed on the air cushion box body. According to the applicant's research, when the plastic sealing ring is sent to the opened air cushion box through the plastic sealing ring feeding assembly, and the plastic sealing ring is directly pressed vertically downward by the pressing ring mechanism, the excess gas between the plastic sealing ring and the air cushion box is not discharged in time due to the instantaneous downward pressure of the pressing ring mechanism, and thus gathers on the lower side of the plastic sealing film, resulting in bulging of the plastic sealing film. When the cover body is pressed downward by force, it is limited by the bulging of the plastic sealing film and cannot be tightly closed with the air cushion box body. The applicant first presses one side of the plastic sealing ring to connect the one side of the plastic sealing ring to the air cushion box, and the other side of the plastic sealing ring is not connected to the air cushion box to allow gas to pass through, so that the excess air between the plastic sealing ring and the air cushion box can be discharged from the other side, and finally presses the entire plastic sealing ring vertically downward to press the entire plastic sealing ring onto the air cushion box while avoiding bulging. To this end, the applicant has improved the pressing ring mechanism, and the embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. Example 1

[0045] A pressure ring mechanism for filling an air cushion foundation, such as Figures 1 to 6 As shown, it includes a bracket 1 and a pressure head assembly 2 and a driving assembly 3 arranged on the bracket 1.

[0046] The pressure head assembly 2 includes a mounting seat 22, a pressure head 21 adapted to the plastic sealing ring of the air cushion foundation box, and a connecting member arranged between the mounting seat 22 and the pressure head 21. The connecting member is configured to enable the pressure head 21 to have a first working state and a second working state. When the pressure head 21 is in the first working state (see Figure 5 ), the abutting surface of the pressing head 21 has a first abutting area at a first height and a second abutting area at a second height, the first height is smaller than the second height, so that one side of the pressing head 21 can press one side of the plastic sealing ring first, and the other side does not press the plastic sealing ring; when the pressing head 21 is in the second working state (see Figure 6 ), the abutting surface of the pressing head 21 is a plane parallel to the horizontal plane, so that the pressing head 21 can press the entire plastic sealing ring to achieve complete connection between the plastic sealing ring and the air cushion box.

[0047] Specifically, the pressure head 21 includes a plurality of independent parts, at least one of the plurality of parts is connected to the connecting member and can move in the up and down direction under the drive of the connecting member, and the remaining parts of the plurality of parts are fixedly connected to the mounting seat 22 and their abutting surfaces are located in the same horizontal plane. The part of the plurality of parts connected to the connecting member is the first part 211, and the remaining parts of the plurality of parts are the second part 212. When there are multiple first parts 211, the multiple first parts 211 are located on the same side, and at least one of the multiple first parts 211 is located on the circumference of the pressure head 21; when there is one first part 211, the first part 211 is preferably arched, and the arc length of the first part 211 is less than or equal to 1 / 2 of the circumference of the pressure head 21.

[0048] In this embodiment, there are one first part 211 and one second part 212, and they are symmetrically arranged along the vertical direction. The symmetrical design of the first part 211 and the second part 212 has good flexibility, more uniform force, and a simple structure.

[0049] The connecting member is preferably a telescopic cylinder 23, which is used to drive the first part 211 to move in the up and down directions so that the pressure head 21 switches between the first working state and the second working state.

[0050] The mounting seat 22 is preferably T-shaped, the second portion 212 is disposed at the bottom of the mounting seat 22 , and the connecting member is mounted at the lower end of the crossbeam of the mounting seat 22 .

[0051] In this embodiment, in order to monitor the pressing force of the pressure head 21, to avoid damage to the air cushion box and the plastic sealing ring due to excessive pressing force, and to avoid incomplete pressing of the air cushion box and the plastic sealing ring due to insufficient pressing force, the pressure head assembly 2 also includes a pressure sensor 27 mounted on the mounting seat 22. In addition, the pressure head assembly 2 also includes a motor 28 connected to the mounting seat 22 and used to drive the mounting seat 22 to move in the up and down direction. The output end of the drive motor 28 is preferably threadedly connected to the mounting seat 22, so as to facilitate fine-tuning of the height and direction of the pressure head 21.

[0052] The pressure head assembly 2 has one or more groups. When there are multiple groups, the multiple groups of pressure head assemblies 2 are arranged at intervals on the connecting plate 41. The output end of the driving assembly 3 is connected to the connecting plate 41 to drive the multiple groups of pressure head assemblies 2 to move synchronously. The driving assembly 3 is preferably a servo module that can drive the pressure head assembly 2 to move up and down. Preferably, the pressing ring mechanism also includes two rods 43 installed on both sides of the connecting plate 41. The two rods 43 extend upward and are slidably connected to the linear bearings 42 installed on the bracket 1, which not only play a guiding role, but also reduce the shaking of the connecting plate 41.

[0053] Working principle:

[0054] When the driving assembly 3 controls the pressure head assembly 2 to move down to a certain height, the output end of the telescopic cylinder 23 moves down and drives the first part 211 to move down, the pressure head 21 switches to the first working state, the first part 211 presses one side of the plastic sealing ring downward to connect it with the air cushion box body, then the output end of the telescopic cylinder 23 moves up and drives the first part 211 to move up to be flush with the second part 212, the pressure head 21 switches to the second working state, the driving assembly 3 controls the pressure head assembly 2 to move down again, the pressure head 21 is completely pressed on the plastic sealing ring, and the plastic sealing ring is pressed onto the air cushion box body.

[0055] It has been verified that the pressing ring mechanism will not cause bulging of the plastic sealing ring, making subsequent capping easier. Example 2

[0056] This embodiment is substantially the same as the embodiment 1, except that the pressure head assembly 2 is different.

[0057] See also Figures 7 to 9 The pressing head assembly 2 includes a mounting seat 22, a pressing head 21 adapted to the plastic sealing ring of the air cushion foundation box, and a connecting piece arranged between the mounting seat 22 and the pressing head 21, the connecting piece is configured to enable the pressing head 21 to have a first working state and a second working state. When the pressing head 21 is in the first working state, the abutting surface of the pressing head 21 has a first abutting area located at a first height and a second abutting area located at a second height, the first height is less than the second height, so that one side of the pressing head 21 can first press one side of the plastic sealing ring, and the other side does not press the plastic sealing ring; when the pressing head 21 is in the second working state, the abutting surface of the pressing head 21 is a plane parallel to the horizontal plane, so that the pressing head 21 can press the entire plastic sealing ring to achieve complete connection between the plastic sealing ring and the air cushion box.

[0058] The connecting piece has a movable joint and an elastic portion 26 .

[0059] The movable joint is mounted on the mounting seat 22, and the pressure head 21 is fixedly connected to the movable joint. Preferably, the movable joint includes a sleeve 24 fixedly connected to the groove of the mounting seat 22 and a sphere 25 movably arranged in the sleeve 24, and the sphere 25 and the sleeve 24 form a rotational fit. Further, the sleeve 24 and the mounting seat 22 are fixedly connected by a first fixing member 221, and the pressure head 21 is fixedly mounted on the connecting portion 251 of the sphere 25 by a second fixing member 252, and the multi-angle rotation of the pressure head 21 is realized by rotating the sphere 25. The first fixing member 221 and the second fixing member 252 include but are not limited to bolts.

[0060] The elastic part 26 abuts between the pressure head 21 and the mounting seat 22, and it makes the pressure head 21 have an initial state of being tilted downward, so that when the pressure head assembly 2 moves downward, one side of the pressure head 21 can first press one side of the plastic sealing ring with the air cushion box body under the action of the elastic force of the elastic part 26. As the pressure head assembly 2 continues to descend, the pressure head 21 rotates and drives the elastic part 26 to compress until the abutting surface of the pressure head 21 is horizontal, so that the pressure head 21 can press the entire plastic sealing ring. Preferably, the inclination angle a of the pressure head 21 in the initial state is 2°~10°, and more preferably 4°~5°. The elastic part 26 is preferably a spring, which abuts against one side of the rotation axis of the pressure head 21.

[0061] Working principle:

[0062] Under the elastic force of the elastic part 26, the pressing head 21 is in the first working state, and the driving assembly 3 controls the pressing head assembly 2 to move downward. The downwardly inclined side of the pressing head 21 can press one side of the plastic sealing ring with the air cushion box body. As the pressing head assembly 2 continues to move downward, the pressing head 21 is subjected to the abutting force of the air cushion box to overcome the elastic force of the elastic part 26 and rotate until the abutting surface of the pressing head 21 is parallel to the horizontal plane. The pressing head 21 is completely pressed on the plastic sealing ring, and the plastic sealing ring is completely pressed onto the air cushion box body.

[0063] It has been verified that the pressing ring mechanism will not cause bulging of the plastic sealing ring, making subsequent capping easier.
