Description

Technical Field

[0001] This utility model relates to the field of preparation technology of health product capsules, and specifically to a continuous packaging device for capsule box structure. Background Technology

[0002] As a type of device that uses a capsule structure as the extraction medium, capsule extraction equipment uses a piercing needle to penetrate the sealing film at the top of a beverage capsule during use. Liquid at a set temperature and pressure is injected into the capsule, and the effective ingredients in the capsule contents are extracted through pressure impregnation extraction to obtain the corresponding beverage.

[0003] In the current technological field, capsule extraction equipment used to produce beverages such as milk tea, finished tea, coffee, and health tea typically employs capsule structures that include rigid or semi-rigid plastic shells. These shells have an open surface for filling with the material, and the opening is sealed with a plastic film after filling to ensure the integrity and hygiene of the material inside the capsule during packaging, transportation, and use. This not only ensures the safety of the beverage but also improves ease of use. However, the packaging method for such capsules often uses individual capsule packaging. While this method ensures the hygiene of the capsules, it is inefficient in continuous sealing, especially in large-scale production, where the sealing process for a single capsule is time-consuming, limiting the improvement of production efficiency and the reduction of production costs. On the other hand, using customized automated molding equipment presents high equipment costs and complex maintenance issues. Utility Model Content

[0004] The technical problem solved by this utility model is to provide a continuous packaging device for capsule box structure, which aims to improve the efficiency of capsule packaging, reduce production costs, and at the same time ensure the integrity and hygiene of the capsule contents, thereby solving the defects in the above-mentioned technical background.

[0005] The technical problem solved by this utility model is achieved by the following technical solution:

[0006] A continuous packaging device for capsule box structures includes a machine frame with a planar turntable on the machine frame and at least four capsule box placement positions on the planar turntable. Four working positions are sequentially arranged outside the planar turntable on the machine frame, namely a feeding working position, a film coating working position, a thermoforming working position, and a unloading working position. The device switches between the capsule box placement positions at different working positions by rotating the turntable.

[0007] The loading station is used to place capsule boxes at the capsule box placement position;

[0008] The film coating station is equipped with a film coating mechanism, which dispenses and matches the plastic sealing film to the capsule boxes entering the film coating station.

[0009] The hot pressing forming station is equipped with a hot pressing head, which can hot press the film-coated capsule box to ensure that the plastic film is tightly bonded to the capsule box and form a sealing effect.

[0010] The unloading workstation is equipped with an unloading assembly, which is a combination of a guide channel, a top-loading mechanism, and a push rod. The two ends of the guide channel correspond to the feeding mechanism and the capsule box placement position, respectively. The top-loading mechanism is formed at the bottom of the capsule box placement position and is used to push the capsule box into the guide channel after it enters the unloading workstation.

[0011] As a further limitation, the planar turntable has a removable base plate formed at the corresponding capsule box placement position, and the base plate has a placement slot that matches the size of the corresponding capsule box.

[0012] As a further limitation, the equipment frame has a reserved manual operation position next to the loading work position of the planar turntable, so that the loading work can be carried out manually.

[0013] As a further limitation, the equipment frame is equipped with a robotic arm or a feeding wheel at the loading work position to achieve automated loading through the robotic arm or the feeding wheel.

[0014] As a further definition, the coating mechanism consists of a film roll roller, a top pressure plate, and a coating assembly. The film roll roller is used to install the plastic sealant roll as a consumable. The plastic sealant roll is continuously fed to the coating work position by cooperating with the rotation of the planar turntable. Plastic sealant films are formed at intervals on the plastic sealant roll, and the plastic sealant films have pre-set annular pre-openings at the outer contour positions of the plastic sealant roll. When the plastic sealant film enters the coating work position, the top pressure plate presses and separates the plastic sealant film at the position of the annular pre-openings, and then the coating assembly performs the coating operation.

[0015] The coating assembly includes a coating roller and a preheating device. The plastic sealant covering the surface of the coating roller is a thermoplastic film material. The preheating device is used to heat the coating roller so that the thermoplastic film material can soften and adhere to the surface of the capsule box after heating.

[0016] The coating assembly includes a coating roller and a peeling roller. The plastic sealant covering the surface of the coating roller is a single-sided adhesive film material. The adhesive coating position of the film material corresponds to the heat-pressing position of the capsule box, and a release film is formed on the adhesive coating surface of the film material. The peeling roller is arranged opposite to the coating roller and is used to separate the release film. After separating the release film, the coating roller is used to attach the adhesive plastic sealant to the surface of the capsule box.

[0017] As a further limitation, the temperature and pressure of the hot press head can be adjusted according to the different materials of the plastic sealing film to adapt to capsule boxes of different specifications and materials.

[0018] As a further limitation, the equipment frame is also equipped with an air-cooling device between the hot pressing and unloading workstations. The air-cooling device is used to cool the capsule box after the film is applied, ensuring that the plastic seal film can be cooled and cured quickly, and preventing the plastic seal film from falling off or deforming on the capsule box.

[0019] As a further limitation, the device also includes a position detection device, which is a combination of a position sensor and an infrared sensor. There are multiple position detection devices, which are respectively mounted on the planar turntable and different working positions to detect the positioning status of the capsule box.

[0020] As a further limitation, the device also includes a film coating quality inspection device, which is a vision inspection system. The camera of the vision inspection system faces the material guide channel and uses image recognition technology to determine whether the film coating of the capsule box passing through the material guide channel is qualified.

[0021] As a further limitation, the device also includes a programmable logic controller (PLC) as a control unit. Each action unit of the device is connected to the PLC and can achieve precise control of each component through programming, ensuring the automation and continuity of the entire packaging process.

[0022] Beneficial effects: The continuous packaging device for capsule box structure of this utility model significantly improves packaging efficiency and reduces the need for manual operation through continuous automated operation, thereby reducing production costs; at the same time, its packaging method can ensure the consistency and stability of each capsule box in the packaging process, avoiding the inefficiency caused by packaging individual capsules separately.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0026] See Figure 1 A preferred embodiment of a continuous packaging device for a capsule box structure is provided. In this embodiment, the main structure of the continuous packaging device is a machine frame 1. The bottom of the machine frame 1 is fixed in position by a support structure. The machine frame 1 has a structural cavity inside, which is used to assemble various working components.

[0027] The upper surface of the equipment frame 1 is provided with a planar turntable 7. The planar turntable 7 has a disc structure with a reserved shaft assembly position in the middle. The turntable shaft 14 is assembled through this shaft assembly position. The lower part of the turntable shaft 14 is connected to a stepper motor and can drive the entire planar turntable 7 to rotate, thereby realizing the switching between different working positions.

[0028] Four capsule box placement positions 13 are evenly distributed on the upper surface of the planar turntable 7. Each placement position 13 corresponds to the size of a capsule box, ensuring that the capsule box is stably placed on the capsule box placement position 13.

[0029] Four working positions are respectively arranged on the outer side of the planar turntable 7 on the equipment frame 1. The four working positions correspond to the loading working position (position A), the film coating working position (position B), the thermoforming working position (position C), and the unloading working position (position D) at the three o'clock, six o'clock, nine o'clock, and twelve o'clock directions. In this embodiment, the planar turntable 7 rotates counterclockwise. Through the rotation of the planar turntable 7, a single capsule placement position 13 can start from the loading working position, pass through the film coating working position, the thermoforming working position, and finally reach the unloading working position to complete the entire packaging process. Each working position is equipped with a corresponding mechanical device to realize a specific packaging function.

[0030] The loading station is used to place capsule boxes in the capsule box placement station 13. In different embodiments, this placement operation can be performed by a manual operation station or by automated equipment.

[0031] In this embodiment, the loading station is operated manually. Specifically, a manual operation position is reserved at the lower part of the device at the position shown in the figure. A material frame is placed next to the manual operation position, and the capsule boxes after loading are stacked in the material frame. During the loading operation, the operator stands directly at the manual operation position and sequentially places the capsule boxes from the material frame into the capsule box placement positions 13 at the loading station position as the planar turntable 7 rotates, ensuring that each capsule box placement position 13 is replenished in a timely manner. Under this loading method, the operating cost is low, and the operator can also observe the working status of other components of the device at the manual operation position to promptly detect and handle any abnormalities. In addition, the manual loading method has the advantage of high flexibility, allowing the loading speed and quantity to be adjusted according to actual production needs, thereby improving overall work efficiency.

[0032] In other embodiments, the loading operation at the loading station can also be achieved through automated equipment, such as a robotic arm or a feeding wheel. The robotic arm can precisely grasp and place capsules, ensuring accuracy and efficiency in loading. The feeding wheel is suitable for large-volume continuous loading, sequentially feeding capsules into the loading station by rotating it.

[0033] The above three feeding methods can be flexibly selected according to actual production needs to achieve the best production results.

[0034] At the laminating station, each capsule box in the capsule box placement position 13 is covered with a layer of plastic sealing film as a protective seal. This process is automatically completed by the laminating mechanism 8, ensuring that each box of capsules is evenly and completely covered with plastic sealing film.

[0035] The laminating mechanism 8 can utilize existing film lamination equipment in the prior art. It only needs to separate the corresponding sealing film unit from the sealing film roll to achieve automatic distribution of the sealing film. Then, it can ensure that the distributed sealing film unit is stably aligned and pre-fixed on the surface of the corresponding capsule box.

[0036] For example, the corresponding laminating mechanism 8 consists of a film roll, a top pressure plate, and a laminating assembly. The film roll is used to mount the plastic sealant roll, which is a consumable material. The rotation of the film roll enables continuous feeding of the plastic sealant. The plastic sealant roll has spaced-formed plastic sealant films, with pre-drilled annular holes on its outer contour. When the plastic sealant enters the laminating station, the top pressure plate presses and separates the plastic sealant at the pre-drilled annular holes to achieve automatic distribution. The laminating assembly then performs the laminating operation on the capsule container surface.

[0037] The appropriate laminating components can be selected based on the type of shrink wrap during the lamination process.

[0038] When the corresponding sealing film is a thermoplastic film material, the corresponding laminating assembly includes a laminating roller and a preheating device. Utilizing the properties of the thermoplastic film material, the preheating device preheats the film to a suitable temperature for shaping and bonding. The laminating roller then evenly presses the preheated film onto the capsule box surface, ensuring no air bubbles or wrinkles between the film and the capsule box, resulting in a tight lamination. The preheating device typically includes heating elements and a temperature control system to ensure the film reaches the ideal temperature range before entering the laminating roller.

[0039] If the shrink wrap is a non-thermoplastic, single-sided adhesive film material, the corresponding laminating assembly may include a laminating roller and a peeling roller. The peeling roller's function is to peel off the protective layer of the single-sided adhesive film, exposing the adhesive side. During the peeling process, the roller surface needs to have a certain amount of friction to ensure that the protective layer can be smoothly separated from the film. Subsequently, the peeled adhesive side will contact the laminating roller, which is responsible for accurately adhering the film to the surface of the capsule box.

[0040] At the thermoforming station, the coated capsule box is thermoformed by a thermoforming head to ensure a tight bond between the plastic film and the capsule box, creating a seal. The corresponding thermoforming head and the structural components that enable its thermoforming function are integrated onto a thermoforming head support 4. A lifting cylinder 6 is connected to the top of the thermoforming head support 4, and the lifting cylinder 6 is mounted on the equipment frame 1 via a lifting cylinder bracket 3. To improve the operational stability of the thermoforming head support 4, guide rods 5 are provided on both sides of the lifting cylinder 6 to ensure precise vertical movement. During the thermoforming process, the lifting cylinder 6 controls the up-and-down movement of the thermoforming head support 4, allowing the thermoforming head to accurately align with the coated capsule box and apply appropriate thermoforming pressure.

[0041] The temperature and pressure of the hot press head are precisely controlled by the control system, which can be adjusted according to different plastic sealing film materials to adapt to capsule boxes of different specifications and materials.

[0042] A material unloading assembly is provided at the unloading workstation. This assembly includes a material guide channel 9, a material ejection mechanism, and a push rod. The material guide channel 9 is located outside the capsule placement position 13 corresponding to the unloading workstation. It is a U-shaped channel with a slanted bottom and a smooth surface. The width of the U-shaped channel is slightly larger than the width of the capsule, and it has a flared side baffle structure with a material-gathering effect on one side of the capsule placement position 13. The material ejection mechanism is located at the bottom of the unloading workstation corresponding to the capsule placement position 13, and includes a vertical push rod and a material ejection block 12 formed at the top of the vertical push rod. In this embodiment, the push rod is powered by a telescopic cylinder 10 mounted on a telescopic cylinder bracket 2, and a material ejection block 11 is mounted at the end of the push rod.

[0043] When the capsule box after hot pressing enters the unloading position along with the capsule box placement position 13, the corresponding top material block 12 pushes the hot-pressed capsule box out of the capsule box placement position 13. Before the top material block 12 pushes the capsule box out of the capsule box placement position 13, the corresponding push material block 11 is moved to the right side of the capsule box placement position 13 by the push rod driven by the telescopic cylinder 10. After the hot-pressed capsule box is pushed out of the capsule box placement position 13 along with the top material block 12, the push material block 11 retracts and pushes the pushed capsule box into the guide channel 9. The capsule box then slides along the inclined surface of the guide channel 9 onto the feeding belt, which serves as the feeding mechanism, to proceed to the next process and complete the unloading operation.

[0044] Furthermore, the device is equipped with a programmable logic controller (PLC) as the control unit, to which all action units are connected. Precise control of each component is achieved through programming, ensuring the automation and continuity of the entire packaging process. Through these designs, this embodiment only requires a start switch 15 on the side of the equipment frame 1 corresponding to the manual operation position, enabling one-button start operation and automating the entire packaging process, significantly reducing the need for manual intervention. Simultaneously, the use of the PLC not only improves packaging efficiency and reduces production costs but also ensures the consistency and stability of capsule packaging, avoiding the inefficiency caused by individually packaging each capsule.

[0045] In another embodiment, to enhance the practicality of the device, a removable base is added to the corresponding capsule box placement position 13 on the planar turntable 7. The base has placement slots adapted to the size of the corresponding capsule box, allowing for flexible adaptation to capsule boxes of different sizes by replacing bases with different placement slots. This design not only improves the flexibility of the device but also makes changing product specifications simple and quick, significantly improving production efficiency.

[0046] In addition, to further improve packaging efficiency and quality, a cooling device is installed on the equipment frame 1 between the hot pressing and unloading stations. This cooling device uses air cooling to quickly cool the capsule box after hot pressing to solidify the plastic seal and prevent deformation or adhesion during subsequent packaging or transportation.

[0047] In another embodiment, the device is also equipped with a position detection device, which is a combination of a position sensor and infrared technology. Multiple position detection devices are installed on the planar turntable and different working positions to detect the positioning status of the capsule boxes. The device also includes a film-coating quality inspection device, which is a vision inspection system. Its camera faces the material guide channel and uses image recognition technology to determine whether the film coating of the capsule boxes passing through the material guide channel is qualified.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical content of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
