Description

Technical Field

[0001] This utility model relates to a cold sealing mechanism for aluminum foil sealing beverage bottles. Background Technology

[0002] Sealing technology is widely used in modern processing plants. In beverage bottling, heat sealing is frequently employed. Heat sealing, also known as heat bonding, is completely different from adhesive bonding and plastic bag bonding methods. Heat sealing requires no external materials; it relies solely on the melting of the packaging material itself upon heating to achieve adhesion. Beverage bottles typically use aluminum foil for sealing. Instant heating of the aluminum foil melts it, causing it to adhere to the bottle neck. Since only the portion of the foil corresponding to the bottle neck needs to be heated, the entire foil does not need to be heated. After heat sealing, a certain amount of time is required for cooling. While still molten, the adhesion between the foil and the bottle neck is insufficient, making the foil prone to shifting. To address this technical problem, Chinese Utility Model Patent Specification CN 206337004 U discloses a two-in-one sealing mechanism for beverage filling production, which incorporates a cold sealing machine cooled by water circulation. This cold sealing machine performs a second pressing and cooling of the aluminum foil, increasing the adhesion between the bottle neck and the aluminum foil and rapidly cooling the foil to prevent displacement. However, this prior art uses a linear conveyor to transport the beverage bottles, requiring the cold sealing and bottle conveying actions to be intermittently switched, impacting production efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a cold sealing mechanism for aluminum foil sealing of beverage bottles, including a worktable, a rotating component and a cylindrical cam;

[0004] The rotating assembly includes a rotating shaft rotatably mounted on a worktable, on which an upper turntable and a lower turntable are fixed at intervals along the axis of the rotating shaft, wherein the upper turntable is located above the lower turntable;

[0005] The upper turntable is equipped with multiple cold sealing heads that are circumferentially spaced around the axis of rotation;

[0006] The lower turntable is equipped with multiple bottle-carrying assemblies that are circumferentially spaced around the axis of rotation. The number of bottle-carrying assemblies is equal to the number of cold-sealing heads, and each bottle-carrying assembly corresponds to a cold-sealing head in the upper and lower positions. Each bottle-carrying assembly slides closer to or further away from the cold-sealing head between an upward position and a downward position.

[0007] The cylindrical cam is fixedly mounted on the worktable and is located below the lower turntable. The upper end face of the cylindrical cam is provided with a cam profile, and the lower end of each bottle-carrying assembly is provided with a roller that is always in contact with the cam profile. When the lower turntable and each bottle-carrying assembly on it rotate with the rotating shaft, the cam profile forces each bottle-carrying assembly to slide back and forth between the rising position and the falling position.

[0008] Each bottle carrier assembly is loaded with a beverage bottle, the bottle neck of which is heat-sealed with aluminum foil. When the bottle carrier assembly is in the rising position, the aluminum foil abuts against the lower end face of the cold air head, and when the bottle carrier assembly is in the falling position, the aluminum foil leaves the lower end face of the cold sealing head.

[0009] Each cold sealing head is provided with a water inlet, a water storage chamber and a water outlet. The water inlet and the water outlet are respectively connected to the water storage chamber, which stores water for cooling the lower end face of the cold sealing head.

[0010] The rotating assembly also includes a water supply mechanism that is connected to the inlet and outlet of each cold end cap, and the water supply mechanism is configured to send water into the water storage chamber through the inlet and draw water out of the water storage chamber through the outlet.

[0011] The workbench is also equipped with a drive mechanism for driving the rotating shaft to rotate.

[0012] This invention utilizes a rotating assembly to drive the beverage bottles in a rotating conveyor. During the bottle conveying process, the aluminum foil at the bottle neck can be cold-sealed, enabling continuous operation and improving production efficiency. Simultaneously, a water storage chamber within the cold-sealing head stores water for cooling the lower surface of the head, enhancing the cooling effect. Furthermore, the design using cylindrical cams to force the bottle-carrying components to slide up and down, combined with the rotation of the rotating assembly, results in a simple structure that is easy to implement.

Detailed Implementation

[0028] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution.

[0029] like Figures 1 to 14 A beverage bottle sealing aluminum foil cold sealing mechanism is shown, including a worktable 10, a rotating assembly and a cylindrical cam 20;

[0030] The rotating assembly includes a rotating shaft 30 rotatably mounted on the worktable 10. An upper turntable 301 and a lower turntable 302 are fixed at intervals along the axis of the rotating shaft 30, wherein the upper turntable 301 is located above the lower turntable 302.

[0031] The upper turntable 301 is equipped with a plurality of cold sealing heads 40 that are circumferentially spaced around the axis of rotation;

[0032] The lower turntable 302 is equipped with a plurality of bottle carrier assemblies 50 that are circumferentially spaced around the axis of rotation. The sliding direction of each bottle carrier assembly 50 is parallel to the axis of rotation. The number of bottle carrier assemblies 50 is equal to the number of cold sealing heads 40. Each bottle carrier assembly 50 corresponds to a cold sealing head 40 in a vertical position. Each bottle carrier assembly 50 slides closer to or further away from the cold sealing head 40 between a rising position and a falling position.

[0033] The cylindrical cam 20 is fixedly mounted on the worktable 10 and is located below the lower turntable 302. The upper end face of the cylindrical cam 20 has a cam profile 201. The lower end of each bottle-carrying assembly 50 has a roller 501 that is always in contact with the cam profile 201. When the lower turntable 302 and each bottle-carrying assembly 50 on it rotate with the rotating shaft 30, the cam profile 201 forces each bottle-carrying assembly 50 to slide back and forth between an upward position and a downward position. In this embodiment, the cylindrical cam can use existing technology. Its cam profile has a peak and a valley. Each bottle-carrying assembly is in an upward position when its roller reaches the peak of the cam profile, and in a downward position when its roller reaches the valley of the cam profile. See details for further information. Figure 6 As shown, the roller of the middle bottle carrier assembly reaches the peak of the cam profile, therefore, the middle bottle carrier assembly is in the rising position. Meanwhile, the roller of the outermost bottle carrier assembly is at the valley of the cam profile, therefore, the outermost bottle carrier assembly is in the falling position.

[0034] Each bottle carrier assembly 50 is loaded with a beverage bottle 60, the bottle mouth of which is heat-sealed with aluminum foil 601. When the bottle carrier assembly 50 is in the rising position, the aluminum foil 601 abuts against the lower end face 401 of the cold air head, and when the bottle carrier assembly 50 is in the falling position, the aluminum foil 601 leaves the lower end face 401 of the cold sealing head.

[0035] Each cold sealing head 40 is provided with a water inlet 402, a water storage cavity 403 and a water outlet 404. The water inlet 402 and the water outlet 404 are respectively connected to the water storage cavity 403. The water storage cavity 403 stores water for cooling the lower end face 401 of the cold sealing head, thereby allowing the lower end face 401 of the cold air head to contact and cool the aluminum foil 601.

[0036] The rotating assembly also includes a water supply mechanism that is connected to the inlet 402 and outlet 404 of each cold sealing head respectively. The water supply mechanism is configured to send water into the water storage chamber 403 through the inlet 402 and extract water from the water storage chamber 403 through the outlet 404.

[0037] The worktable 10 is also provided with a drive mechanism (not shown in the figure) for driving the rotating shaft 30 to rotate. In this embodiment, the drive mechanism can be installed at the bottom of the worktable. The drive mechanism can adopt existing technology. For example, the drive mechanism may include a motor and a transmission mechanism disposed between the motor output shaft and the rotating shaft. The motor drives the rotating shaft to rotate with the help of the transmission mechanism.

[0038] The water supply mechanism includes a water tank 303 and a water pump 304 mounted on the upper turntable 301. In this embodiment, the water tank 303 and the water pump 304 can be fixedly installed at the bottom of the upper turntable 301. The inlet of the water pump 304 is connected to the water tank 303 via a water pipe, and the outlet of the water pump 304 is connected to the inlet 402 of each cold sealing head via a water pipe. This allows the water pump to connect to all the cold sealing heads simultaneously. The outlet 404 of each cold sealing head is connected to the water tank 303 via a water pipe. This allows the water pump to deliver water from the water tank into the water storage chamber of each cold sealing head, while simultaneously allowing the water in the water storage chamber of each cold sealing head to flow back to the water tank from the outlet, forming a circulation. The water supply mechanism disclosed in this technical solution has a simple structure, is easy to implement, and can replace the water in the water storage chamber of each cold sealing head, ensuring the cooling effect.

[0039] The bottle carrier assembly 50 includes a bottom plate 502, a middle plate 503 and a top plate 504 arranged sequentially from bottom to top;

[0040] The base plate 502 is located below the lower turntable 302, and the middle plate 503 is located above the lower turntable 302;

[0041] When the bottle carrier assembly 50 is in the descending position, the middle plate 503 falls onto the lower turntable 302 and is supported by the lower turntable 302. In this embodiment, the bottle carrier assembly can be returned to the descending position by the gravity of the bottle carrier assembly.

[0042] The middle plate 503 leaves the lower turntable 302 when the bottle carrier assembly 50 is in the rising position;

[0043] Multiple guide pins 505 are connected between the base plate 502 and the middle plate 503. Each guide pin 505 can slide through the lower turntable 302. In addition to connecting the base plate 502 and the middle plate 503, each guide pin also slides with the lower turntable to guide the bottle carrier assembly to slide up and down.

[0044] The roller 501 is mounted on the base plate 502;

[0045] A column 506 for supporting the top plate 504 is connected between the middle plate 503 and the top plate 504.

[0046] The top plate 504 is provided with a fork-shaped component for clamping the neck of the beverage bottle 601 and supporting the beverage bottle 601. The bottle carrier assembly disclosed in this technical solution has a simple structure, reasonable design, and is easy to implement.

[0047] The fork-shaped assembly includes two symmetrical fork arms 70, the inner end 701 of each fork arm is rotatably mounted on the top plate 504, and the outer end 702 of each fork arm extends out of the top plate 504. The outer ends 702 of the two fork arms are used to clamp the neck of the beverage bottle.

[0048] A tension spring 80 is connected between the two fork arms 70 to bring the outer ends 702 of the two fork arms closer together. In this embodiment, each fork arm 70 is provided with a hanging rod 703 in the middle for the end of the tension spring 80 to be hooked.

[0049] The fork-shaped component disclosed in this technical solution has a reasonable design, simple structure, and is easy to implement.

[0050] In this embodiment, in addition to the structure described above, the fork-shaped component can also adopt other existing structures, such as a beverage filling clamping device disclosed in Chinese Invention Patent CN 117819456 A.
