Description

Technical Field

[0001] This application relates to the field of cosmetic manufacturing technology, and in particular to an automatic stoppering device. Background Technology

[0002] In the cosmetic production process, after liquid products, emulsion products, or powder products are all filled into cosmetic containers such as jars or bottles, the cosmetic containers need to be sealed. At this time, an inner stopper is generally used to seal the opening of the cosmetic container to complete the sealing process. During the sealing process, a stoppering device is generally used for production.

[0003] A search revealed a Chinese patent disclosure for a stoppering device (authorization announcement number CN208279288U), comprising a conveying mechanism and a pressure roller mounted horizontally above the conveying mechanism. The pressure roller and the conveying mechanism form a channel for cosmetic containers to pass through. The surface linear velocity of the pressure roller is set to be equal to the conveying speed of the conveying mechanism. The cosmetic containers are conveyed from one end of the channel to the other end by the conveying mechanism, and the stoppering operation is completed by the pressure roller. This patented technology can sequentially feed cosmetic containers into the channel, and during the rotation of the pressure roller, it can create a squeezing force with the conveying mechanism, thus completing the stoppering operation during the conveying process without needing to pause during the stoppering process. This improves the overall efficiency of the production line and ensures that the conveying speed of the conveying mechanism is not affected by the stoppering operation.

[0004] However, the above-mentioned device still has some drawbacks in actual use. The most obvious one is that when cosmetic containers are conveyed on the conveyor belt for stoppering, the lack of a special clamping component results in poor stability of the containers during the stoppering process. During the stoppering process, the containers are very easy to tip over due to uneven force. Once the containers tip over, it will not only lead to the failure of the stoppering operation, but may also damage the containers, increase equipment maintenance costs, and reduce overall production efficiency. Utility Model Content

[0005] In view of the above-mentioned problems existing in the prior art, the main objective of this application is to provide an automatic plugging device.

[0006] The technical solution of this application is as follows: an automatic plugging device includes a frame, a mounting frame is fixedly connected to the top of the frame, and clamping arms are slidably mounted at both ends inside the mounting frame. One clamping arm has an arc-shaped clamping plate b on its inner wall, and the other clamping arm has an arc-shaped clamping plate a on its inner wall. The arc-shaped clamping plate a and the arc-shaped clamping plate b are symmetrically arranged. A limit rod a is fixedly connected to one end inside the mounting frame, and a bidirectional lead screw is rotatably connected to the other end inside the mounting frame. The clamping arms are all slidably connected to the limit rod a, and the clamping arms are all threadedly connected to the bidirectional lead screw.

[0007] By adopting the above technical solution, the rotation of the bidirectional screw causes the clamping arm to slide along the limiting rod a, which in turn causes the arc-shaped clamping plate a and the arc-shaped clamping plate b to move towards each other, thus firmly clamping the container and effectively preventing the container from tipping over due to uneven force during the sealing process.

[0008] In a preferred embodiment, the mounting bracket is provided with a pressing assembly. The pressing assembly includes a fixing member located at the center of the bottom. A plugging head is located below the fixing member. A plurality of limiting rods b are fixedly connected to the top of the plugging head. The limiting rods b are slidably connected to the fixing member. A telescopic spring is sleeved on the outer periphery of the limiting rods b and located between the fixing member and the plugging head.

[0009] By adopting the above technical solution, through the downward movement of the fixing part and the stopper head, the limiting rod b cooperates with the telescopic spring to ensure that when the stopper head contacts the container stopper, it can not only ensure sufficient pressure to complete the stoppering action, but also benefit from the buffering effect of the telescopic spring.

[0010] In a preferred embodiment, an identification component is provided on the top of the rack. The identification component includes an infrared transmitter and an infrared receiver fixedly installed on the outer wall of the mounting frame. A conveyor belt is installed on the top of the rack, and the infrared receiver and infrared transmitter are respectively located on both sides of the conveyor belt.

[0011] By adopting the above technical solution, the position of the container on the conveyor belt can be monitored in real time through an identification component consisting of an infrared transmitter and an infrared receiver.

[0012] In a preferred embodiment, each of the clamping arms has a screw inserted inside, and each screw has a locking nut threaded onto its outer circumference. The arc-shaped clamping plate b and arc-shaped clamping plate a are connected to the clamping arm via the screw and the locking nut, respectively.

[0013] By adopting the above technical solution, the detachable arc-shaped clamp structure facilitates quick replacement and adjustment according to different container specifications.

[0014] In a preferred embodiment, a stopper cylinder is fixedly installed on the top of the mounting bracket and between the bidirectional lead screw and the limiting rod a, and the piston rod of the stopper cylinder is fixedly connected to the center of the fixing member.

[0015] By adopting the above technical solution, the piston rod of the plugging cylinder can be extended and retracted to push the fixed part and the plugging head downward, thereby realizing the plugging operation.

[0016] In a preferred embodiment, a servo motor a is fixedly mounted on the outer side of the mounting bracket, and the output shaft of the servo motor a is fixedly connected to the rotation shaft of the bidirectional lead screw.

[0017] By adopting the above technical solution, the rotation of the output shaft of servo motor a can drive the bidirectional lead screw to rotate.

[0018] In a preferred embodiment, a controller is fixedly mounted on the outside of the mounting bracket, and a cosmetic container is held between the arc-shaped clamp b and the arc-shaped clamp a.

[0019] By adopting the above technical solution and setting the controller, the electrical equipment on the rack can be controlled.

[0020] Compared with the prior art, the advantages and positive effects of this application are as follows: 1. In this application, when the cosmetic container is transported to the designated position, the drive source drives the bidirectional lead screw to rotate, causing the clamping arm to slide along the limiting rod a, which in turn drives the arc-shaped clamping plate a and the arc-shaped clamping plate b to move towards each other, firmly clamping the container. This effectively prevents the container from tipping over due to uneven force during the stoppering process, solves the problem of poor stability of traditional containers, significantly reduces the failure rate of stoppering operations, and provides a reliable guarantee for subsequent stable stoppering.

[0021] 2. In this application, by means of the downward movement of the fixing part and the stopper head, the limiting rod b cooperates with the telescopic spring to ensure that when the stopper head contacts the container stopper, it can both ensure sufficient pressure to complete the stoppering action and avoid excessive pressure from damaging the container through the buffering effect of the telescopic spring.

Detailed Implementation

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0025] Reference Figure 1-5 An automatic plugging device includes a frame 1, with a mounting frame 3 fixedly connected to the top of the frame 1. Clamping arms 11 are slidably mounted at both ends inside the mounting frame 3. One clamping arm 11 has an arc-shaped clamping plate b10 on its inner wall, and the other clamping arm 11 has an arc-shaped clamping plate a9 on its inner wall. The arc-shaped clamping plates a9 and b10 are symmetrically arranged. A limit rod a13 is fixedly connected to one end inside the mounting frame 3, and a bidirectional lead screw 14 is rotatably connected to the other end inside the mounting frame 3. All are slidably connected to the limiting rod a13, and all clamping arms 11 are threadedly connected to the bidirectional lead screw 14. When the cosmetic container is transported to the designated position, the drive source drives the bidirectional lead screw 14 to rotate, causing the clamping arms 11 to slide along the limiting rod a13, which drives the arc-shaped clamping plate a9 and the arc-shaped clamping plate b10 to move towards each other, firmly clamping the container. This effectively prevents the container from tipping over due to uneven force during the stoppering process, solves the problem of poor stability of traditional containers, greatly reduces the failure rate of stoppering operations, and provides a reliable guarantee for subsequent stable stoppering.

[0026] Specifically, the mounting frame 3 has a pressing assembly inside, which includes a fixing member 17 located at the bottom center. Below the fixing member 17 is a stopper head 15. Several limiting rods b18 are fixedly connected to the top of the stopper head 15. Through the downward movement of the fixing member 17 and the stopper head 15, the limiting rods b18 cooperate with the telescopic springs 19, ensuring that when the stopper head 15 contacts the container stopper, it provides sufficient pressure to complete the stoppering action, while the telescopic springs 19 provide cushioning to prevent excessive pressure from damaging the container. The limiting rods b18 are all slidably connected to the fixing member 17. Telescopic springs 19 are sleeved around the outer periphery of the limiting rods b18 and between the fixing member 17 and the stopper head 15. The top of the frame 1 has an identification assembly, which includes an infrared transmitter 4 and an infrared receiver 5 fixedly installed on the outer wall of the mounting frame 3. The infrared transmitter 4 and the infrared receiver 5 form the identification group. The system monitors the position of containers on conveyor belt 2 in real time. When a cosmetic container enters the sealing area, the infrared light in the infrared transmitter 4 is blocked, and the light intensity received by the infrared receiver 5 decreases sharply. This triggers the circuit to generate an electrical signal change, thereby determining that the container has arrived. Subsequently, the controller 16 controls the drive source at the bidirectional screw 14 to start, realizing automatic and continuous sealing operations, effectively improving production efficiency and reducing manual intervention. The top of the frame 1 is equipped with a conveyor belt 2, and the infrared receiver 5 and infrared transmitter 4 are respectively set on both sides of the conveyor belt 2. The clamping arms 11 are all internally connected with screws 8, and the outer periphery of the screws 8 is threaded with locking nuts 12. The detachable arc-shaped clamping plate structure facilitates quick replacement and adjustment according to different container specifications, enhancing the versatility and applicability of the equipment. The arc-shaped clamping plates b10 and a9 are connected to the clamping arms 11 through screws 8 and locking nuts 12, respectively.

[0027] Specifically, a stopper cylinder 7 is fixedly installed on the top of the mounting frame 3, between the bidirectional lead screw 14 and the limiting rod a13. By extending and retracting the piston rod of the stopper cylinder 7, the fixing part 17 and the stopper head 15 can be pushed downward to achieve the stoppering operation. The piston rod of the stopper cylinder 7 is fixedly connected to the center of the fixing part 17. A servo motor a6 is fixedly installed on the outside of the mounting frame 3. By rotating the output shaft of the servo motor a6, the bidirectional lead screw 14 can be driven to rotate. The output shaft of the servo motor a6 is fixedly connected to the rotation shaft of the bidirectional lead screw 14. A controller 16 is fixedly installed on the outside of the mounting frame 3. By setting the controller 16, the electrical equipment on the frame 1 can be controlled. The cosmetic container is held between the arc-shaped clamp b10 and the arc-shaped clamp a9.

[0028] Working principle: First, the cosmetic container to be capped is brought into the mounting frame 3 by the conveyor belt 2. Before entering the mounting frame 3, the stopper or cap is pre-placed on the cosmetic container. When the cosmetic container is brought into the capping area by the conveyor belt 2, the infrared light in the infrared emitter 4 is blocked, and the light intensity received by the infrared receiver 5 decreases sharply. The trigger circuit generates an electrical signal change, thereby determining that the container has arrived. Then, the controller 16 controls the servo motor a6 to start, so as to drive the bidirectional lead screw 14 to rotate, so that the clamping arm 11 slides along the limit rod a13, driving the arc-shaped clamping plate a9 and the arc-shaped clamping plate b10 to move towards each other, firmly clamping the container, effectively preventing the container from tipping over due to uneven force during the capping process. At the same time, the extension and retraction of the piston rod of the capping cylinder 7 can drive the fixing part 17 and the capping head 15 to press down. The buffering effect of the extension spring 19 prevents the container from being damaged by excessive pressure, so as to realize automatic and continuous capping operation.
