Description

Technical Field

[0001] The utility model relates to the technical field of filling equipment, in particular to a sponge feeding mechanism of an air cushion box. Background Art

[0002] Air cushion foundation is a portable makeup product, usually using a sponge air cushion as a carrier. After dipping an appropriate amount of liquid foundation, it is gently patted on the face. It has the advantages of being light, breathable, and easy to use, and is becoming more and more popular among consumers.

[0003] The air cushion filling process mainly includes opening the box, placing the sponge, filling, supplying the ring, pressing the ring, and closing the lid. However, the sponge placement process is usually done manually, which is inefficient. Therefore, a sponge feeding mechanism is urgently needed to achieve automated sponge feeding. Utility Model Content

[0004] The purpose of the utility model is to provide a sponge feeding mechanism for an air cushion box.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A sponge feeding mechanism for an air cushion box, comprising:

[0007] A sponge carrier, the sponge carrier having one or more stations for placing sponges, each station having a through hole;

[0008] A sponge suction cup having an accommodating cavity extending axially therethrough, the sponge suction cup being movably arranged and having a material taking position and a material feeding position. When the sponge suction cup is in the material taking position, the sponge suction cup is located above the sponge carrier and the accommodating cavity thereof faces the through hole of the sponge carrier;

[0009] A sponge pushing component, the sponge pushing component includes a first sponge pushing member movably arranged below the through hole, a second sponge pushing member movably arranged above the accommodating chamber, a first sponge driving member connected to the first sponge pushing member, and a second sponge driving member connected to the second sponge pushing member. Controlled by the first sponge driving member, the first sponge pushing member has a tendency to move upward and push all or part of the sponge into the accommodating chamber; controlled by the second sponge driving member, the second sponge pushing member has a tendency to move downward and push the sponge in the accommodating chamber away from the sponge suction cup.

[0010] Because the sponge is porous, it is difficult to absorb it through negative pressure suction, making it difficult to automatically deliver the sponge to the air cushion box. The utility model uses a first sponge pusher to push the sponge upward from the bottom to the accommodating cavity of the sponge suction cup. Under the action of the first sponge pusher, the sponge can deform and partially or completely enter the accommodating cavity of the sponge suction cup and abut against the inner wall of the accommodating cavity of the sponge suction cup. The sponge can be moved with the sponge suction cup. When it reaches the feeding position, the second sponge pusher pushes the sponge downward, and the sponge can overcome the abutment force between the sponge suction cup and the sponge suction cup, thereby separating from the sponge suction cup and entering the air cushion box.

[0011] Preferably, the minimum inner diameter of the accommodating cavity is smaller than the maximum outer diameter of the sponge. The sponge suction cup and the sponge can be interference fit.

[0012] Preferably, the inner diameter of the accommodating cavity gradually decreases from bottom to top. The lower end of the accommodating cavity is large to facilitate the entry of the sponge, and the lower end is small to clamp the sponge and prevent it from falling.

[0013] In some embodiments, the accommodating cavity is in a frustum shape.

[0014] Preferably, when the sponge suction cup has a picking state and a feeding state, when the sponge suction cup is in the picking state, the lower end of the accommodating cavity is the end with the largest inner diameter; when the sponge suction cup is in the feeding state, the lower end of the accommodating cavity is the end with the smallest inner diameter.

[0015] Further preferably, the sponge feeding mechanism further comprises a flip driving member for driving the sponge suction cup to flip, and the sponge suction cup can be switched between the material taking state and the material feeding state under the control of the flip driving member.

[0016] Preferably, the sponge feeding mechanism also includes a bracket and a third sponge driving member connected to the bracket and used to drive the bracket to slide between the material picking position and the material feeding position, and the sponge suction cup, the second sponge pushing member and the second sponge driving member are arranged on the bracket.

[0017] Preferably, the sponge feeding mechanism further comprises a sponge conveyor belt, and an end of the sponge conveyor belt is connected to the sponge carrier.

[0018] Further preferably, the sponge feeding mechanism also includes a sponge container for accommodating sponges and a sponge container driving assembly connected to the sponge container, and the sponge container driving assembly is configured to drive the sponge container to move so as to feed the sponge in the sponge container from the sponge container to the sponge conveyor belt according to a preset route.

[0019] In some embodiments, the inner wall of the sponge container has a spiral track extending upward, with a notch formed in the upper spiral turn of the spiral track, and the sponge conveyor belt is located below the notch. The sponge container drive assembly is a vibration motor. The sponge container and the sponge container drive assembly cooperate to cause the sponge to move along a predetermined path. The specific principle of the vibration plate in the prior art can be referred to.

[0020] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0021] The sponge feeding mechanism of the present invention includes a sponge carrier, a sponge suction cup, and a sponge pushing assembly. A first sponge pushing member pushes the sponge, causing the sponge to deform and partially or completely enter the sponge suction cup's accommodating cavity, where it abuts against the inner wall of the cavity. As the sponge suction cup moves from a material-removing position to a material-feeding position, a second sponge pushing member pushes the sponge downward, overcoming the abutting force between the sponge suction cup and the sponge, thereby separating from the sponge suction cup and entering the air cushion box. This sponge feeding mechanism requires no manual operation, is highly efficient, and has promising application prospects. BRIEF DESCRIPTION OF THE DRAWINGS

Such repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed.

[0036] Example 1

[0037] A sponge feeding mechanism for an air cushion box, such as Figures 1 to 7 As shown, it includes a sponge carrier 1, a movable sponge suction cup 2 and a sponge pushing component.

[0038] The sponge carrier 1 has one or more stations 11 for placing sponges, and each station 11 has a through hole. Preferably, the sponge carrier 1 has 2 to 6 stations 11. In this embodiment, Figure 2 、 Figure 4 and Figure 6 As shown, the sponge carrier 1 has four workstations 11, and the four workstations 11 are arranged at equal intervals along the left-right direction.

[0039] The sponge suction cup 2 has one or more corresponding to the workstations 11. When there are multiple sponge suction cups 2, the multiple sponge suction cups 2 are also arranged at equal intervals along the left and right directions, and the distance between two adjacent sponge suction cups 2 is equal to the distance between two adjacent workstations 11. Taking one of the sponge suction cups 2 as an example, the sponge suction cup 2 has a receiving cavity 21 that runs through it along its axial direction. The minimum inner diameter of the receiving cavity 21 is smaller than the maximum outer diameter of the sponge, so that the sponge suction cup 2 can be interference-fitted with the sponge, so that when the sponge is accommodated in the receiving cavity 21, the sponge can abut against the inner wall of the receiving cavity 21 without falling. As a preferred embodiment, Figure 7 As shown, the inner diameter of the accommodating chamber 21 gradually decreases from bottom to top. The lower end of the accommodating chamber 21 is large to facilitate the entry of the sponge, and the upper end is small to facilitate the clamping of the sponge and prevent the sponge from falling. Furthermore, the maximum inner diameter of the accommodating chamber 21 is larger than the maximum outer diameter of the sponge, thereby facilitating the entry of the sponge. In this embodiment, the accommodating chamber 21 is in the shape of a cone. The sponge suction cup 2 has a material picking position and a material feeding position. When the sponge suction cup 2 is in the material picking position, the sponge suction cup 2 is located above the sponge carrier 1 and its accommodating chamber 21 is opposite to the through hole of the sponge carrier 1, which is convenient for pushing the sponge into the accommodating chamber 21. The following section discusses this in detail.

[0040] The sponge pushing assembly includes a first sponge pushing member 42 movably disposed below the through hole of the workstation 11 of the sponge carrier 1, a second sponge pushing member 43 movably disposed above the accommodating chamber 21, a first sponge driving member connected to the first sponge pushing member 42, and a second sponge driving member connected to the second sponge pushing member 43. Controlled by the first sponge driving member, the first sponge pushing member 42 has a tendency to move upward and push all or part of the sponge into the accommodating chamber 21; controlled by the second sponge driving member, the second sponge pushing member 43 has a tendency to move downward and push the sponge in the accommodating chamber 21 away from the sponge suction cup 2. The first sponge pushing members 42 can be optionally provided in one group or multiple groups corresponding to multiple workstations 11 of the carrier. When provided in one group, the first sponge pushing members 42 are controllably movable in the left-right direction, thereby pushing the sponges on the multiple workstations 11 into the sponge suction cup 2 one by one. When the first sponge pushing member 42 pushes the sponge, it moves upward to push the sponge into the accommodating chamber 21 of the sponge suction cup 2 and then returns to its original position. The second sponge pushers 43 are arranged in a one-to-one correspondence with the sponge suction cups 2. The second sponge pushers 43 are located directly above the corresponding accommodating cavity 21 of the sponge suction cup 2. When there are multiple second sponge pushers 43, they can be connected by a connecting member and move synchronously.

[0041] In order to enable the sponge suction cup 2 to switch between the material picking position and the material feeding position, the sponge feeding mechanism further includes a bracket 41 and a third sponge driving member connected to the bracket 41 and used to drive the bracket 41 to slide between the material picking position and the material feeding position. The sponge suction cup 2, the second sponge pushing member 43 and the second sponge driving member are arranged on the bracket 41 and move synchronously with the bracket 41. The third sponge driving member can be a three-axis motion component that moves in the left and right, front and back, and up and down directions, or a two-axis motion component that moves in two of these directions, or a single-axis motion component that moves in one of these directions. The specific structure of the three-axis motion component, the two-axis motion component or the single-axis motion component can refer to the existing technology and will not be described in detail in this application.

[0042] When the sponge suction cup 2 moves with the sponge, there is a risk of the sponge inside falling out. In order to prevent the sponge from falling out, the sponge feeding mechanism is also equipped with a flip driving member 3 for driving the sponge suction cup 2 to flip. Controlled by the flip driving member 3, the sponge suction cup 2 can flip 180 degrees, so that the maximum inner diameter of the accommodating cavity 21 of the sponge suction cup 2 faces upward and the minimum inner diameter faces downward, preventing the sponge from falling out. That is, the sponge suction cup 2 has a material-retrieving state and a material-feeding state. When the sponge suction cup 2 is in the material-retrieving state, the lower end of the accommodating cavity 21 is the end with the largest inner diameter, which facilitates the entry of the sponge; after the sponge enters, the sponge suction cup 2 is controlled by the flip driving member 3 to flip 180 degrees, and the sponge suction cup 2 switches to the feeding state, so that the lower end of the accommodating cavity 21 of the sponge suction cup 2 is the end with the smallest inner diameter. In this way, even if the sponge suction cup 2 moves, the sponge inside will not fall out. Furthermore, the flip driving member 3 is arranged on the bracket 41 and corresponds one-to-one with the sponge suction cup 2.

[0043] The sponge feeding mechanism also includes a sponge conveyor belt 6, a sponge container 5 for accommodating sponges, and a sponge container driving assembly connected to the sponge container 5. The sponge container driving assembly is configured to drive the sponge container 5 to move so as to feed the sponge in the sponge container 5 from the sponge container 5 to the sponge conveyor belt 6 according to a preset route. The end of the sponge conveyor belt 6 is connected to the sponge carrier 1. The sponge conveyor belt 6 has a blocking portion 61, which allows the sponges to be sorted one by one along the conveying direction of the sponge conveyor belt 6.

[0044] Furthermore, the inner wall of the sponge container 5 has a spiral track 51 extending spirally upward, and a notch 52 is provided on the spiral circle of the spiral track 51 located above. The sponge conveyor belt 6 is located below the notch 52. The sponge container driving component is a vibration motor. The vibration of the vibration motor is used to vibrate, so that the sponge in the sponge container 5 is arranged in an orderly manner on the spiral track 51 and moves along the spiral track 51 to the notch 52, and enters the sponge conveyor belt 6 through the notch 52.

[0045] The sponge feeding mechanism also includes a telescopic member 72 that can be extended and retracted in the vertical direction, a sponge feeding conveyor belt 7 that is rotatably mounted on the telescopic member 72, and a blocking box 71 that is located above the sponge feeding conveyor belt 7 and blocks the sponge feeding conveyor belt 7 on all sides. The blocking box 71 has a sponge feeding port 711 on its upper side and a groove 712 on its side adjacent to the sponge container 5 for allowing sponge to pass out. The end of the sponge feeding conveyor belt 7 extends above the sponge container 5. Through the telescopic movement of the telescopic member 72 and the rotation of the sponge feeding conveyor belt 7, the sponge feeding conveyor belt 7 can be adjusted to a suitable position, making it convenient for the operator to add sponge to the blocking box 71 through the sponge feeding port 711. The sponge can then enter the sponge container 5 along the conveying path of the sponge feeding conveyor belt 7, which is very convenient.

[0046] Working principle:

[0047] The sponge is fed into the sponge loading conveyor belt 7 through the sponge feeding port 711, and the sponge enters the sponge container 5 along the movement path of the sponge loading conveyor belt 7. Through the vibration of the vibration motor, the sponge in the sponge container 5 is arranged in order on the spiral track 51 and moves along the spiral track 51 to the gap 52, enters the sponge conveyor belt 6 through the gap 52, and enters the work station 11 of the sponge carrier 1 along the transportation path of the sponge conveyor belt 6.

[0048] The first sponge pushing member 42 moves upward and passes through the through hole of the work station 11 to push the sponge into the accommodating cavity 21 of the sponge suction cup 2. The flip driving member 3 controls the sponge suction cup 2 to flip 180°, so that the sponge suction cup 2 switches from the picking state to the feeding state (when the sponge suction cup 2 is in the picking state, the lower end of the accommodating cavity 21 is the end with the largest inner diameter, which is convenient for the sponge to enter; when the sponge suction cup 2 is in the feeding state, the lower end of the accommodating cavity 21 is the end with the smallest inner diameter). After the third sponge driving member brings the sponge suction cup 2 into the feeding position, the second sponge pushing member 43 pushes the sponge downward to make the sponge detach from the sponge suction cup 2 and enter the air cushion box.

[0049] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
