Description

Technical Field

[0001] This utility model relates to the field of bottle cap processing technology, and in particular to the pressing and limiting structure of a bottle cap film applicator. Background Technology

[0002] The current bottle cap laminating machine has a relatively simple pressing and limiting structure. Its main function is to work with the cap placement window and the laminating mechanism to ensure accurate placement of the bottle cap and to perform operations such as laminating and removing the cap.

[0003] These operations mainly rely on the bottle cap being placed within the pressing and limiting structure, and then a servo motor driving a rotary table to precisely move it to the designated position. However, existing pressing and limiting structures have some problems in practical applications:

[0004] When placing the bottle cap, the bottle cap needs to be precisely aligned with the support and engaged with the support through the cavity at the bottom of the bottle cap. Otherwise, it is easy to cause poor engagement of the bottle cap, which increases the complexity of the operation and reduces the efficiency of the operation.

[0005] More specifically, if the bottle cap is not precisely aligned with the support post, it is difficult to achieve effective locking, leading to unstable placement and eventual detachment, requiring repositioning. This not only reduces work efficiency but may also cause more serious problems. Because the stroke of the film-pressing mechanism is fixed (the stroke by which the film-pressing mechanism presses down to contact the bottle cap), if the bottle cap does not fully contact the support post, it will cause the bottle cap to be subjected to excessive pressure during the film-pressing process and be damaged, thus requiring machine shutdown for cleaning and repair. This directly affects the continuity of the production process and production efficiency.

[0006] Based on the above shortcomings, we propose a pressing and limiting structure for a bottle cap film applicator. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of existing technologies and optimize the pressing and limiting structure of existing bottle cap film applicators to improve the convenience of bottle cap placement and thus improve the efficiency of bottle cap film applicator.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A pressing and limiting structure for a bottle cap applicator includes a rotating table and multiple pressing and limiting structures. The pressing and limiting structures are arranged around the top of the rotating table near its outer periphery. Each pressing and limiting structure includes a cap-laying support column and a guide cylinder. The cap-laying support column is centrally installed inside the guide cylinder. A support pad is installed at the top of the cap-laying support column, and a telescopic part is installed at the bottom of the cap-laying support column. The telescopic part is slidably connected inside a base. A first spring is provided around the telescopic part on the corresponding end faces of the cap-laying support column and the base.

[0010] Furthermore, the rotating platform is driven by a bottom servo motor and installed at the bottom of the bottle cap applicator. The three pressing and limiting structures at the top correspond to the cap placement window, the film pressing mechanism, and the cap removal mechanism, respectively.

[0011] Furthermore, a guide funnel is installed at the top of the guide cylinder. The guide funnel is higher than the cover support and has a larger internal diameter than the guide cylinder. The guide cylinder and the guide funnel are provided with a cover removal groove facing the outer wall of the rotating table.

[0012] Furthermore, the supporting pad is made of rubber, and its end face matches the end face of the cover support column and is bonded to the top of the cover support column.

[0013] Furthermore, the top of the cover support column has a first mounting hole extending through the bottom, and the top of the telescopic part has a second mounting hole. The cover support column and the telescopic part are installed by connecting the first mounting hole and the second mounting hole with bolts.

[0014] Furthermore, the top of the base is provided with a movable slot, and a lifting slot is provided inside the movable slot, the diameter of which is larger than that of the movable slot.

[0015] Furthermore, the bottom of the telescopic part is provided with a lifting limit plate. The diameter of the lifting limit plate is larger than that of the movable slot and is built into the lifting slot. A second spring is installed between the bottom of the lifting slot and the lifting limit plate. When the second spring is in the open state, the lifting limit plate abuts against the top of the lifting slot.

[0016] Furthermore, the first spring is provided in several parts, and the two ends of the first spring abut against the limiting holes opened around the corresponding end faces of the cover support and the base. When the first spring is in the open state, the lifting limiting plate abuts against the top of the lifting slot hole.

[0017] Compared with the prior art, the pressing and limiting structure of the bottle cap film applicator of this utility model has the following beneficial effects:

[0018] Improving the ease of bottle cap placement: By setting a guide tube outside the cap placement support and installing a guide funnel at the top of the guide tube, the bottle cap can be smoothly engaged with the cap placement support even if it is not precisely aligned with the cap placement support, thanks to the guidance of the guide funnel and the guide tube. This greatly reduces the difficulty of operation and improves the ease of bottle cap placement.

[0019] Protecting bottle caps from damage: The bottom of the cap support is equipped with a telescopic part, which is connected to the base through a first spring. When the bottle cap is subjected to excessive pressure, the telescopic part can compress downwards to absorb some of the pressure, thereby preventing the bottle cap from being damaged by excessive pressure during the pressing process. Even if it is not completely locked onto the support, the support pad is made of rubber, which can also buffer the pressure to a certain extent and protect the bottle cap.

[0020] Improved production efficiency: Because bottle caps are easier to place and can be protected from damage during the molding process, downtime for cleaning and repair due to improper placement or damage of bottle caps is reduced, thus improving the continuity and efficiency of the production process.

[0021] Easy to install and maintain: The cover support and telescopic part are connected by bolts, which facilitates installation and disassembly, and allows for the replacement of the first spring component.

[0022] In summary, the pressing and limiting structure of the bottle cap film applicator of this utility model, through optimized design, improves the convenience of bottle cap placement, protects bottle caps from damage, increases production efficiency, ensures structural stability and reliability, and is easy to install and maintain.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0030] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be provided below with reference to relevant embodiments, and several embodiments of this utility model will be given. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this utility model more thorough and complete.

[0031] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Example

[0033] like Figure 1-4 As shown, this utility model provides a technical solution: a pressing and limiting structure for a bottle cap film applicator, including a rotating table 1 and multiple pressing and limiting structures 2. The pressing and limiting structures 2 are arranged around the top of the rotating table 1 near the outer periphery. The rotating table 1 is driven by a bottom servo motor and installed at the bottom of the bottle cap film applicator. The three pressing and limiting structures 2 at the top correspond to the cap placement window, the film pressing mechanism, and the cap removal mechanism, respectively.

[0034] The cap placement window is used by a person or a robotic arm to place the bottle cap into the pressing and limiting structure 2; the film pressing mechanism is used to apply a film to the bottle cap placed in the pressing and limiting structure 2; and the cap removal mechanism is used to remove the bottle cap after the film has been applied from the pressing and limiting structure 2.

[0035] It should be added that the cap placement window is a specific area or opening on the cap laminating machine. It serves as the entrance for the cap to enter the pressing and limiting structure 2. In actual operation, the operator can manually place the cap into the corresponding pressing and limiting structure 2 through this window. On automated production lines, automated equipment such as robotic arms can also accurately place the cap into the pressing and limiting structure 2 through the cap placement window to ensure that the cap can be placed smoothly and accurately in the designated position, preparing for the subsequent laminating operation.

[0036] The film pressing mechanism is one of the core components of the bottle cap laminating machine. Its main function is to apply film to the bottle cap that has been placed in the pressing and limiting structure 2. After the bottle cap is accurately placed in the pressing and limiting structure 2, the rotating table 1 will move the pressing and limiting structure 2 to the bottom of the film pressing mechanism. At this time, the film pressing mechanism will adhere the film tightly to the bottle cap according to the preset program or parameters (force and stroke).

[0037] The cap removal mechanism is another important component of the bottle cap applicator. Its main function is to remove the bottle cap that has been applicated from the pressing and limiting structure 2. After the bottle cap is applicated, the rotating table 1 will move the pressing and limiting structure 2 to the cap removal mechanism. At this time, the cap removal mechanism will remove the bottle cap from the pressing and limiting structure 2 through a specific mechanical structure or action (generally, the cylinder extends and retracts to drive the release block, which works in conjunction with the cap removal groove 222 in this case).

[0038] The pressing and limiting structure 2 of this scheme includes a cap-laying support column 21 and a guide cylinder 22. The cap-laying support column 21 is centrally installed inside the guide cylinder 22. A support pad 23 is installed at the top of the cap-laying support column 21 to support the bottle cap and prevent the bottle cap from being damaged during placement or pressing. A telescopic part 24 is installed at the bottom of the cap-laying support column 21. The telescopic part 24 is slidably connected inside the base 25, so that the cap-laying support column 21 can move downward when pressure is applied. A first spring member 26 is provided around the telescopic part 24 on the corresponding end faces of the cap-laying support column 21 and the base 25 to provide a restoring force to return the cap-laying support column 21 to its original position after it is subjected to pressure. Example

[0039] like Figure 1-4 As shown, a guide funnel 221 is installed at the top of the guide cylinder 22. The guide funnel 221 is higher than the cap placement support 21 and its inner diameter is larger than that of the guide cylinder 22. This design allows the bottle cap to be smoothly attached to the cap placement support 21 by the guide funnel 221 and the guide cylinder 22 even if it is not precisely aligned with the cap placement support 21. The guide cylinder 22 and the guide funnel 221 are provided with a cap removal groove 222 facing the outer wall of the rotating table 1, which makes it easy for the cap removal mechanism to remove the cap with the film applied from the pressing and limiting structure 2.

[0040] The support pad 23 is made of rubber and its end face matches the end face of the cap support 21. It is bonded to the top of the cap support 21. This design can provide sufficient support and buffer pressure to protect the bottle cap.

[0041] The top of the cover support 21 has a first mounting hole 211 extending through the bottom, and the top of the telescopic part 24 has a second mounting hole 241. The cover support 21 and the telescopic part 24 are installed by bolting the first mounting hole 211 and the second mounting hole 241. This design facilitates installation and disassembly, and allows for the replacement of the first spring component 26.

[0042] The top of the base 25 has a movable slot 251, and a lifting slot 252 is provided inside the movable slot 251. The diameter of the lifting slot 252 is larger than that of the movable slot 251. This design provides sufficient space for the telescopic part 24 to move.

[0043] The telescopic part 24 is provided with a lifting limit plate 242 at the bottom. The diameter of the lifting limit plate 242 is larger than that of the movable slot 251 and is built into the lifting slot 252 to prevent the telescopic part 24 from coming out of the base 25. A second spring member 253 is installed between the bottom of the lifting slot 252 and the lifting limit plate 242. When the second spring member 253 is in the open state, the lifting limit plate 242 abuts against the top of the lifting slot 252 and is in the pre-operation state.

[0044] The first spring member 26 is provided in several parts. The two ends of the first spring member 26 abut against the limiting holes 27 that are opened around the corresponding end faces of the cover support 21 and the base 25. This design enables the first spring member 26 to work more stably and provide sufficient restoring force. When the first spring member 26 is in the open state, the lifting limiting plate 242 abuts against the top of the lifting slot hole 252 and is in the working state.

[0045] The working process of this utility model is as follows: When using the pressing and limiting structure of the bottle cap laminating machine, firstly, the bottle cap is placed manually or by a robotic arm into the pressing and limiting structure 2 corresponding to the cap placement window. The bottle cap is smoothly secured to the cap placement support 21 by the guide funnel 221 and guide cylinder 22. The support pad 23 supports the bottle cap. Then, the rotating table 1 rotates under the drive of the servo motor, moving the pressing and limiting structure 2 with the bottle cap placed below the laminating mechanism. The laminating mechanism presses down to perform the laminating operation on the bottle cap. During the laminating process, if the bottle cap is subjected to pressure (including if the bottle cap does not fully contact the support pad 23), the cap placement support 2... 1 will move downwards, and the telescopic part 24 will slide within the base 25. The first spring 26 and the second spring 253 will be compressed to absorb some of the pressure. During this process, the bottle cap will be pressed by the film pressing mechanism to contact the support pad 23 (for cases where the bottle cap is not fully in contact with the support pad 23), protecting the bottle cap from damage. After the film is applied, the rotating table 1 will continue to rotate, moving the film-applied bottle cap below the cap removal mechanism. The cap removal mechanism will remove the bottle cap from the pressing and limiting structure 2 through the cap removal groove 222. Finally, the cap placement support 21 will return to its original position under the restoring force of the first spring 26 and the second spring 253.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
