Description

A screw-on mechanism for a dairy product packaging box and a production system for boxed dairy products. Technical Field

[0001] This utility model relates to the field of dairy product packaging production, and in particular to a screw-on mechanism for dairy product packaging boxes and a production system for boxed dairy products. Background Technology

[0002] The capping system, an indispensable part of modern dairy packaging technology, directly impacts production efficiency and product quality. Traditional capping systems are relatively complex, including a platform and support columns fixed to the bottom of the platform to support it. The platform primarily holds the dairy product cartons to be capped. A capping arm is located above the platform; this device precisely clamps the cap onto the cap opening of the dairy product cartons and completes the capping action.

[0003] However, the caps of dairy product packaging boxes come in various positions, some at the top center, some on the top side, and others at the edge. To accommodate these different cap positions and reduce equipment investment costs, some manufacturers choose to handle the capping of various dairy product packaging boxes using the same capping system. However, this method requires adjusting the positioning of the capping arm during conversion, which is cumbersome, time-consuming, and requires professional personnel, thus increasing production costs and complexity to some extent.

[0004] With continuous technological advancements, automated capping systems have undergone several upgrades and are now widely used in the dairy packaging industry. However, replacing them with more intelligent packaging equipment often means significant cost investment, which is not easily achieved by many manufacturers.

[0005] In light of the above, improvements to the old-style screw-on cap system are particularly important. Developing a screw-on capping mechanism that can accommodate various cap positions, is easy to operate, requires no professional personnel, and allows for precise and rapid adjustment of the capping device's position is of great significance for the upgrading and development of the dairy packaging industry. Summary of the Invention

[0006] The purpose of this invention is to overcome the aforementioned shortcomings in the existing technology and provide a screw-on mechanism for dairy product packaging boxes and a production system for boxed dairy products. This screw-on mechanism can handle dairy product packaging boxes with various lid positions, is simple to operate, requires no professional personnel, and allows for precise and rapid adjustment of the screw-on device's position, facilitating widespread application.

[0007] In a first aspect, the present invention provides a screw-on mechanism for a dairy product packaging box, comprising the following structure:

[0008] A storage platform for placing dairy product packaging boxes to be capped, and the storage platform is provided with a through groove;

[0009] A support column is used to support the storage platform. One end of the support column passes through the through groove and forms a detachable fixed connection with the storage platform. The outer diameter of the support column in the through groove is smaller than the width of the through groove. The storage platform can be moved by adjusting the fixed position of the support column in the through groove.

[0010] This utility model provides a screw-on mechanism for dairy product packaging boxes. The mechanism cleverly incorporates a through-slot on the placement platform and redesigns the connection between the support column and the platform. The support column passes through the through-slot, achieving a detachable and fixed connection with the platform. The width of the through-slot is greater than the outer diameter of the support column, allowing easy adjustment of the support column's position within the slot, thereby moving the placement platform. When changing dairy product packaging boxes with different cap positions, simply disengaging the support column from the platform and adjusting its position within the through-slot allows for precise movement of the platform, indirectly readjusting the screw-on arm's positioning. This screw-on mechanism can handle dairy product packaging boxes with various cap positions, is easy to operate, and allows for precise and rapid positioning and replacement of the screw-on device without the need for professional personnel, greatly improving production efficiency and convenience, and laying a solid foundation for widespread application.

[0011] As a preferred structure of this utility model, it also includes a cap-screwing arm, which is disposed above the placement platform and is used to cap or screw on dairy product packaging boxes.

[0012] As a preferred structure of this utility model, the end of the cap-screwing arm is provided with a pneumatic gripper mechanism, including a cylinder and a gripper, wherein the cylinder is used to drive the gripper to hold or release the bottle cap.

[0013] As a preferred structure of this utility model, the storage platform is a circular structure; the edge of the storage platform is provided with a plurality of clamping grooves at intervals, the clamping grooves being used to place dairy product packaging boxes; the support column is a rotatable structure.

[0014] The support column is a rotatable structure, and the placement platform is fixedly connected to the support column. Rotating the support column can drive the placement platform to rotate. The placement platform is set as a circular structure with several clamping grooves at intervals along the edge. In use, the dairy product packaging box to be capped is placed in one of the clamping grooves. After the capping mechanism is used to cap the box, the placement platform rotates, and the capping mechanism processes the packaging box in the next clamping groove. The capped packaging box is rotated to a specific position and conveyed to the next processing device. The entire structure is simple to operate and enables streamlined production.

[0015] Preferably, the size of the clamping groove is adjustable. The clamping can be adjusted adaptively according to the size of the retaining box.

[0016] As a preferred structure of this utility model, the edge of the storage platform is provided with four through slots spaced apart in the circumferential direction, and each through slot is adapted to a support column.

[0017] As a preferred structure of this utility model, the through groove is arc-shaped, with its center on the same side as the center of the storage platform. The four through grooves are of the same size and are evenly spaced along the circumferential edge of the storage platform.

[0018] The study found that the four through slots and four matching support columns, respectively set in the four directions of the circular storage platform, not only have high structural stability, but also make it easier to operate when screwing on the cap for positioning.

[0019] Meanwhile, since the positional difference between the lids of packaging boxes at different lid positions is not very large, the improved method of this utility model allows for the adjustment of the gap between the width of the through groove and the outer diameter of the support column according to actual operation. The gap will not differ significantly, and the entire structure is highly operable. The through groove is set to be arc-shaped, with four through grooves spaced equally and symmetrically arranged in pairs, which facilitates adjustment, effectively shortens the adjustment time, and ensures accuracy.

[0020] In a preferred embodiment of this invention, a support bracket is connected to the end of the support column furthest from the placement platform. The support bracket improves the stability of the support column and also facilitates the addition of mechanisms, allowing the support column to rotate.

[0021] As a preferred structure of this utility model, the support column is a telescopic structure. This telescopic structure ensures that the entire capping mechanism can adapt to capping packaging boxes of different heights.

[0022] As a preferred structure of this utility model, the end of the support column near the storage platform is provided with a threaded section, which passes through the through groove. Nuts are respectively provided on the threaded sections on the upper and lower sides of the through groove. In use, the nuts on the upper and lower sides are larger than the width of the through groove. The bottom nut can serve as a support platform for the storage platform. By tightening or loosening the upper nut, the support column can be fixed and disassembled from the storage platform, making operation simple.

[0023] In a second aspect, the present invention provides a production system for packaged dairy products, comprising a sterilization mechanism for dairy product packaging boxes, a filling mechanism for dairy product packaging boxes, and a screw-on mechanism for dairy product packaging boxes as described above, connected in sequence.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] This utility model provides a screw-on mechanism for dairy product packaging boxes. The mechanism cleverly incorporates a through-slot on the placement platform and redesigns the connection between the support column and the platform. One end of the support column passes through the through-slot, achieving a detachable and fixed connection with the placement platform. The through-slot's width is greater than the outer diameter of the support column, allowing for easy adjustment of the support column's position within the slot, thereby moving the placement platform. When changing dairy product packaging boxes with different cap positions, simply disengaging the support column from the platform and adjusting its position within the through-slot allows for precise movement of the platform, indirectly readjusting the screw-on arm's positioning. This screw-on mechanism can handle dairy product packaging boxes with various cap positions, is easy to operate, and requires no professional personnel to perform precise and rapid cap-screwing device positioning and replacement, greatly improving production efficiency and convenience, and laying a solid foundation for widespread application.

[0035] Example 1

[0036] The caps of dairy product packaging boxes come in various positions, some at the top center, some on the top side, and others at the edge. To accommodate these different cap positions and reduce equipment investment costs, some manufacturers choose to handle the capping of various dairy product packaging boxes using a single capping system. However, this method requires adjusting the positioning of the capping arm during conversion, which is cumbersome, time-consuming, and requires professional personnel, thus increasing production costs and complexity to some extent.

[0037] With continuous technological advancements, automated capping systems have undergone several upgrades and are now widely used in the dairy packaging industry. However, replacing them with more intelligent packaging equipment often means significant cost investment, which is not easily achieved by many manufacturers.

[0038] As shown in Figures 1-2, this embodiment provides a screw-on mechanism for a dairy product packaging box, comprising the following structure:

[0039] The storage platform 1 is circular in structure; the edge of the storage platform 1 is provided with a plurality of clamping grooves 11, which are used to place dairy product packaging boxes.

[0040] The storage platform 1 has four through slots 12 spaced circumferentially along its edge.

The four through slots 12 are the same size and are evenly spaced along the circumferential edge of the storage platform 1.

[0041] Each of the through slots 12 is equipped with a support column 2, which is used to support the storage platform 1. The outer diameter of the support column 2 is smaller than the width of the through slot 12. One end of the support column 2 passes through the through slot 12 and forms a detachable fixed connection with the storage platform 1. The storage platform 1 can be moved by adjusting the fixed position of the support column in the through slot 12.

[0042] The support column 2 is a rotatable structure.

[0043] It also includes a screw-on cap arm 3, which is located above the storage platform 1 and is used to put on and screw on the dairy product packaging boxes.

[0044] This utility model provides a screw-on mechanism for dairy product packaging boxes. The mechanism cleverly incorporates a through-slot on the placement platform and redesigns the connection between the support column and the platform. The support column passes through the through-slot, achieving a detachable and fixed connection with the platform. The width of the through-slot is greater than the outer diameter of the support column, allowing easy adjustment of the support column's position within the slot, thereby moving the placement platform. When changing dairy product packaging boxes with different cap positions, simply disengaging the support column from the platform and adjusting its position within the through-slot allows for precise movement of the platform, indirectly readjusting the screw-on arm's positioning. This screw-on mechanism can handle dairy product packaging boxes with various cap positions, is easy to operate, and allows for precise and rapid positioning and replacement of the screw-on device without the need for professional personnel, greatly improving production efficiency and convenience, and laying a solid foundation for widespread application.

[0045] In this embodiment, the support column is a rotatable structure, and the placement platform is fixedly connected to the support column.

[0046] This embodiment provides four through slots and four matching support columns, which are respectively set in the four directions of the circular storage platform. This not only ensures high structural stability but also makes it easier to operate when screwing on the cap for positioning.

[0047] Meanwhile, since the positional difference between the lids of packaging boxes at different lid positions is not very large, the improved method of this utility model allows for the adjustment of the gap between the width of the through groove and the outer diameter of the support column according to actual operation. The gap will not differ significantly, and the entire structure is highly operable. The through groove is set to be arc-shaped, with four through grooves spaced equally and symmetrically arranged in pairs, which facilitates adjustment, effectively shortens the adjustment time, and ensures accuracy.

[0048] In some embodiments, the end of the cap-screwing arm 3 is provided with a pneumatic gripper mechanism, including a cylinder and a gripper, wherein the cylinder is used to drive the gripper to hold or release the bottle cap.

[0050] In some embodiments, a support platform 21 is connected to the end of the support column 2 away from the placement platform 1. The support platform can improve the support stability of the support column, and at the same time, facilitate the addition of a mechanism to enable the support column to rotate.

[0051] In some embodiments, the support column 2 is a telescopic structure. This telescopic structure ensures that the entire capping mechanism can adapt to capping packaging boxes of different heights.

[0052] In some embodiments, the support column 2 has a threaded section at one end near the storage platform 1, the threaded section passing through the through groove 12, and nuts 121 are respectively provided on the threaded sections on the upper and lower sides of the through groove 12.
