Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of food packaging equipment technology, and more specifically, to a sealing device for bottled food processing. Background Technology

[0002] Many food products are now packaged, stored, and transported primarily in bags or bottles. Bottled products can be categorized in various ways based on bottle material, volume, and sealing method. The most common method for sealing bottled food is using a cap. One method involves adding a sealing gasket inside the cap and then screwing it on tightly. Another method uses negative pressure inside the bottle combined with a screw-on cap. Yet another method involves designing a sealing layer at the bottle opening and then adding a cap for protection, among many other variations.

[0003] Initially, bottle caps were manually installed on bottles, a process plagued by low efficiency and inconsistent tightening, resulting in significant waste of bottled food. Later, mechanical equipment was invented to tighten caps, replacing manual labor, improving efficiency, and preventing improper tightening. However, for small businesses with limited capital and a limited product range, the equipment they purchase and invest in is often of a single model. If the bottle type changes, the existing equipment becomes insufficient, necessitating the addition of new equipment or parts, or modifications to the existing equipment to accommodate the new product. This increases equipment costs and reduces overall equipment utilization. Therefore, it is necessary to improve and optimize existing technologies to reduce costs and increase equipment utilization. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a sealing device for bottled food processing, which solves the problem that the existing sealing devices for bagged food have poor versatility and need to be improved in terms of overall utilization for some enterprises with limited financial resources.

[0005] According to one aspect, at least one embodiment of this disclosure provides a sealing device for bottled food processing, used for sealing bottles; comprising:

[0006] Workbench;

[0007] The capping component, which is rotatable and slidable relative to the worktable, has a first through groove;

[0008] An adjusting member is rotatably disposed relative to the capping member. The adjusting member has a second through groove, which is set at an angle to the first through groove. The center line of rotation of the capping member coincides with the center line of rotation of the adjusting member.

[0009] The cap gripper passes through both the first through groove and the second through groove, and slides within both grooves. There are several cap grippers arranged in a circular pattern on the cap screwing member, with a clamping space formed between them to secure the cap. The adjusting member rotates to adjust the size of the clamping space.

[0010] For example, a sealing device for bottled food processing provided in at least one embodiment of this disclosure further includes:

[0011] The capping arm is slidably disposed relative to the worktable, and the capping component is rotatably disposed on the capping arm.

[0012] For example, a sealing device for bottled food processing provided in at least one embodiment of this disclosure further includes:

[0013] A first conveyor belt is arranged in a cyclic transmission relative to the workbench for conveying the bottle body;

[0014] An upper bottle support frame is set on the workbench, and the first conveyor belt is wrapped around the upper bottle support frame to support the first conveyor belt in transporting the bottle over a long distance.

[0015] For example, a sealing device for bottled food processing provided in at least one embodiment of this disclosure further includes:

[0016] Two bottle-fixing arms are oscillating relative to the worktable and in opposite directions.

[0017] The bottle-fixing head has an arc-shaped surface, and each of the bottle-fixing arms is provided with a bottle-fixing head. After the bottle-fixing arm swings, the arc-shaped surface abuts against or cancels contact with the bottle body.

[0018] For example, in a sealing device for bottled food processing provided in at least one embodiment of this disclosure, a third through groove is provided on the bottle-fixing arm, and it further includes:

[0019] A sliding seat is slidably disposed relative to the worktable, the bottle-fixing arm is hinged to the sliding seat, and the two bottle-fixing arms are symmetrically distributed relative to the sliding seat;

[0020] The positioning post is slidably disposed in the third through groove and fixedly connected to the upper bottle support frame.

[0021] For example, in a sealing device for bottled food processing provided in at least one embodiment of this disclosure, the number of sliding seats is two, symmetrically distributed on both sides of the first conveyor belt.

[0022] For example, a sealing device for bottled food processing provided in at least one embodiment of this disclosure further includes:

[0023] Two bottle guides are slidably mounted on the upper bottle support frame and symmetrically distributed on both sides above the first conveyor belt. Each bottle guide has an arc-shaped guide rod.

[0024] For example, a sealing device for bottled food processing provided in at least one embodiment of this disclosure further includes:

[0025] The upper cover frame is set on the workbench;

[0026] The second conveyor belt is arranged in a cyclic transmission relative to the upper cover frame, and the second conveyor belt is used to transport the bottle cap;

[0027] The upper cover is slidably disposed relative to the upper cover frame. The upper cover has a cap storage space for receiving the bottle caps conveyed by the second conveyor belt. After the upper cover slides, the upper cover, along with the bottle caps, extends into or unextends into the middle between the capping member and the first conveyor belt.

[0028] For example, in a sealing device for bottled food processing provided in at least one embodiment of this disclosure, the top cover includes:

[0029] The main body is slidably disposed relative to the upper cover frame and located at the end of the second conveyor belt;

[0030] Two sliding members are slidably disposed on the main body, and the gap between the two sliding members forms the storage cover space.

[0031] For example, a sealing device for bottled food processing provided in at least one embodiment of this disclosure further includes:

[0032] A cover member is slidably disposed relative to the second conveyor belt, and the cover member is used to intercept the bottle caps on the second conveyor belt after sliding.

[0033] The beneficial effects of the embodiments disclosed herein are as follows:

[0034] In this disclosure, the preferred number of cap grippers is four. With the center line of the capping mechanism's rotation as the center, viewed from above, an external force is applied to drive the adjusting mechanism to rotate clockwise by a certain angle and then stop rotating. During the clockwise rotation of the adjusting mechanism, the cap grippers gradually move away from the center line, and a clamping space is formed around the four rotating parts. The bottle cap is moved to the bottom of the capping mechanism, and then an external force is applied to drive the adjusting mechanism to rotate counterclockwise until the cap grippers make contact with the outer circumference of the bottle cap. At this point, the rotation of the adjusting mechanism stops. The cap grippers clamp and fix the bottle cap within the clamping space. Then, the bottle cap is moved to the bottle opening, and an external force is applied to drive the capping mechanism to rotate, tightening the bottle cap onto the bottle body, completing the bottle cap sealing operation.

[0035] When the size of the bottle cap changes, the corresponding adjustment component can be rotated counterclockwise to fix bottle caps of different sizes in the clamping space, thus increasing the applicability of the sealing equipment. In addition to normal sealing operations, it can also accommodate bottle caps of different sizes, improving the overall utilization rate of the equipment. Attached Figure Description

[0045] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0046] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0047] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0048] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0049] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0050] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0051] like Figures 1-5 As shown, it illustrates a sealing device for bottled food processing in one embodiment of the present disclosure.

[0052] In some examples, the sealing device includes a workbench 1, a capping component 3, a cap gripper 7, and an adjusting component 5; the capping component 3 is rotatable and slidable relative to the workbench 1 and has a first through groove 4; the adjusting component 5 is rotatable relative to the capping component 3 and has a second through groove 6, which is angled with the first through groove 4, and the center line of rotation of the capping component 3 coincides with the center line of rotation of the adjusting component 5; the cap gripper 7 passes through both the first through groove 4 and the second through groove 6, and slides within both the first through groove 4 and the second through groove 6, and there are several cap grippers 7, which are circumferentially distributed on the capping component 3, forming a clamping space 9 in the middle of the several cap grippers 7 for fixing the bottle cap 8; after the adjusting component 5 rotates, it is used to adjust the size of the clamping space 9.

[0053] For example, such as Figures 1-5 As shown, the preferred number of cap grippers 7 is four. With the center line of rotation of the capping component 3 as the center, looking down at the capping component 3, an external force is applied to drive the adjusting component 5 to rotate clockwise by a certain angle and then stop rotating. During the clockwise rotation of the adjusting component 5, the cap grippers 7 gradually move away from the center line, and the four rotating components form a clamping space 9 around them. The bottle cap 8 is moved to the bottom of the capping component 3, and then an external force is applied to drive the adjusting component 5 to rotate counterclockwise until the cap grippers 7 and the outer circumference of the bottle cap 8 make contact. At this point, the rotation of the adjusting component 5 is stopped. The cap grippers 7 clamp and fix the bottle cap 8 within the clamping space 9. Then, the bottle cap 8 is moved to the bottle mouth of the bottle body 2, and an external force is applied to drive the capping component 3 to rotate, tightening the bottle cap 8 onto the bottle body 2, completing the sealing operation of the bottle cap 8.

[0054] When the size of the bottle cap 8 changes, the corresponding adjustment component 5 can be rotated counterclockwise to fix bottle caps 8 of different sizes in the cap clamping space 9, thereby increasing the applicability of the sealing equipment. In addition to normal sealing operations, it can also accommodate bottle caps 8 of different sizes, thus improving the overall utilization rate of the equipment.

[0055] In some examples, a capping arm 10 is added, which is slidably arranged up and down relative to the worktable 1, and the capping component 3 is rotatably arranged on the capping arm 10.

[0056] For example, such as Figures 1-3 As shown, after the bottle cap 8 is fixed in the clamping space 9, an external force is applied to drive the capping arm 10 to rise and fall, thereby adjusting the distance between the bottle cap 8 and the bottle body 2 and completing the sealing operation between the bottle body 2 and the bottle cap 8.

[0057] In some examples, the sealing equipment has been optimized by adding a first conveyor belt 11 and an upper bottle support frame 12. The first conveyor belt 11 is arranged in a cyclic transmission relative to the workbench 1 and is used to transport the bottle body 2. The upper bottle support frame 12 is arranged on the workbench 1, and the first conveyor belt 11 is wrapped around the upper bottle support frame 12 to support the first conveyor belt 11 in transporting the bottle body 2 over a long distance.

[0058] For example, such as Figures 1-3 As shown, the bottle body 2 is placed on the first conveyor belt 11. With the support of the upper bottle support frame 12, the first conveyor belt 11 transports the bottle body 2 to the bottom of the capping part 3, completing the sealing operation of the bottle body 2 and the cap 8. With the help of the conveying of the first conveyor belt 11, the bottle body 2 is continuously fed, ensuring the continuous operation of the sealing operation.

[0059] In some examples, the sealing equipment has been optimized by adding two bottle-fixing arms 13, bottle-fixing heads 14, sliding seats 17, and positioning posts 18. The two bottle-fixing arms 13 are oscillating relative to the worktable 1 in opposite directions. The bottle-fixing heads 14 have arc-shaped surfaces 15, and each bottle-fixing arm 13 has one bottle-fixing head 14. After the bottle-fixing arm 13 oscillates, the arc-shaped surfaces 15 either contact or release contact with the bottle body 2. The sliding seats 17 are slidably arranged relative to the worktable 1, and the bottle-fixing arms 13 are hinged to the sliding seats 17, with the two bottle-fixing arms 13 symmetrically distributed relative to the sliding seats 17. A third through groove 16 is provided on the bottle-fixing arm 13. The positioning post 18 is slidably disposed within the third through groove 16 and fixedly connected to the upper bottle support frame 12. There are two sliding seats 17, symmetrically distributed on both sides of the first conveyor belt 11.

[0060] For example, such as Figures 1-5As shown, the bottle cap 8 is fixed in the capping space 9. The first conveyor belt 11 transports the bottle body 2 to the bottom of the capping component 3, and then drives the capping arm 10 to slide downward. The capping component 3 brings the bottle cap 8 close to the bottle body 2, and then applies external force to drive the capping component 3 to rotate, thus completing the sealing of the bottle cap 8. When the bottle body 2 is moved to the bottom of the capping component 3, an external force is applied to drive the sliding seat 17 to slide away from the bottle body 2. The sliding seat 17 will drive the bottle fixing arm 13 to move. At the same time, the positioning post 18 and the third through groove 16 slide relative to each other. With the positioning post 18 as the center, the bottle fixing arm 13 swings with the bottle fixing head 14 towards the bottle body 2 until the bottle fixing head 14 makes a squeezing contact with the bottle body 2. There are two bottle fixing arms 13 hinged on a single sliding seat 17. In this embodiment, the number of sliding seats 17 is selected as two, so a total of four bottle fixing heads 14 make squeezing contact with the outer surface of the bottle body 2. With the squeezing and fixing of the four bottle fixing heads 14, the bottle body 2 is prevented from rotating when it is sealed, which improves the stability during operation. At the same time, the arc surface 15 design on the bottle fixing head 14 can avoid the bottle fixing head 14 from causing pressure marks or indentations on the surface of the bottle body 2, ensuring the quality of the outer surface of the bottle body 2.

[0061] After the bottle cap 8 is screwed onto the bottle body 2, an external force is applied to drive the sliding seat 17 closer to the first conveyor belt 11, causing the bottle fixing head 14 to separate from the bottle body 2. The bottle fixing head 14 releases the bottle body 2, preparing for the next tightening and sealing operation between the bottle body 2 and the bottle cap 8. Simultaneously, with the help of the sliding seat 17 and the hinged bottle fixing arm 13, bottles of different sizes can be clamped and fixed. Combined with the cap gripper 7, adjusting component 5, and cap screwing component 3, the applicability of the sealing equipment is expanded, improving the overall utilization rate of the equipment.

[0062] In some examples, the sealing device has been optimized by adding two bottle guides 19, which are slidably mounted on the upper bottle support frame 12. The two bottle guides 19 are symmetrically distributed on both sides above the first conveyor belt 11, and each bottle guide 19 has an arc-shaped guide rod 20.

[0063] For example, such as Figure 1 As shown, the bottles 2 on the first conveyor belt 11 are guided by two symmetrically distributed bottle guides 19. At the same time, by adjusting the distance between the two bottle guides 19, bottles 2 of different sizes can be accommodated. The bottles 2 on the first conveyor belt 11 can also be guided into a row to ensure the smooth progress of the sealing operation.

[0064] In some examples, the sealing equipment has been optimized by adding a top cover frame 21, a second conveyor belt 22, and a top cover component 23. The top cover frame 21 is set on the workbench 1. The second conveyor belt 22 is arranged in a cyclic transmission relative to the top cover frame 21 and is used to transport bottle caps 8. The top cover component 23 is slidably arranged relative to the top cover frame 21 and has a cap storage space 24 for receiving bottle caps 8 transported by the second conveyor belt 22. After the top cover component 23 slides, it extends or cancels the extension of the bottle cap component 3 between the capping component 3 and the first conveyor belt 11.

[0065] The upper cover 23 includes a main body 25 and two sliding members 26. The main body 25 is slidably disposed relative to the upper cover frame 21 and is located at the end of the second conveyor belt 22. The two sliding members 26 are slidably disposed on the main body 25, and the gap between the two sliding members 26 forms a cover storage space 24.

[0066] Furthermore, a cover member 27 was added. The cover member 27 is slidably arranged relative to the second conveyor belt 22. After sliding, the cover member 27 is used to intercept the bottle caps 8 on the second conveyor belt 22.

[0067] For example, such as Figures 1-7 As shown, during operation, bottle caps 8 are placed on the second conveyor belt 22, which then transports them to the main body 25. During the operation of the second conveyor belt 22, the sliding of the cap-blocking members 27 ensures that only one bottle cap 8 is transported to the main body 25 at a time. The cap-blocking members 27 slide using power provided by the existing telescopic cylinders. There are two cap-blocking members 27, symmetrically distributed on both sides of the second conveyor belt 22. At regular intervals, the telescopic cylinders perform work, causing the two cap-blocking members 27 to move away from each other and then back to their initial positions. One bottle cap 8 on the second conveyor belt 22 is then transferred to the main body 25 via the cap-blocking members 27, ensuring single-piece loading of bottle caps and preventing them from scattering around the workbench 1. Similarly, two more cap-blocking members 27 can be added to both sides of the first conveyor to regulate the transport of the bottle body 2 and ensure stable transport of the bottle body 2.

[0068] The bottle cap 8, moving synchronously with the second conveyor belt 22, slides onto the main body 25 by its inertia and eventually stops in the cap storage space 24. Then, an external force is applied to drive the main body 25 to slide towards the capping member 3 until the bottle cap 8 moves below the capping member 3 and the main body 25 stops moving. Then, the cap gripper 7 fixes the bottle cap 8 in the cap clamping space 9. Then, the cap gripper 7 slides upward a certain distance, and an external force is applied to drive the main body 25 away from the capping member 3 and towards the discharge end of the second conveyor belt 22, returning to the initial position. Then, the cap blocking member 27 slides back and forth once, releasing another bottle cap 8.

[0069] The size of the cap storage space 24 can be adjusted by using the sliding slider 26, making it suitable for bottle caps 8 of different sizes. Combined with the cap gripper 7, adjusting member 5, and cap screwing member 3, this expands the applicability of the sealing equipment and improves the overall utilization rate of the equipment.

[0070] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
