Description

Technical Field

[0001] This utility model belongs to the field of wine packaging machinery technology, and in particular relates to a pneumatic actuator for removing wine labels. Background Technology

[0002] Wine labels are tags affixed to wine bottles. In modern industrial production, high-speed labeling machines are typically used to attach labels to the bottles. Because the adhesive on freshly applied labels has not yet cured, and most wine bottles are smooth glass, labels are prone to warping, curling, and other defects during transport. To ensure finished product quality, defective labels must be promptly removed.

[0003] Currently, two main methods of wine label removal are manual and machine removal, but both have significant drawbacks: manual removal is not only inefficient and prone to missing labels, but also cannot keep pace with high-speed production lines; while conventional machine removal equipment, due to its fixed structure, is difficult to adapt to labels made of different materials (such as paper, plastic, and metal foil) and bottles of different shapes (such as curved or angular). Each time the label or bottle design is changed, the equipment parameters need to be readjusted, severely impacting production efficiency. Especially when handling bottles with special shapes, the nozzle positions of existing equipment are fixed and cannot be flexibly adjusted according to the bottle's curvature, resulting in unsatisfactory removal results.

[0004] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a pneumatic actuator for label removal, which has the advantages of improving label removal efficiency, adapting to bottles of different materials and shapes, and high nozzle installation stability, effectively solving the problem of low label removal efficiency that is common in conventional technical means.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a pneumatic actuator for removing wine labels, comprising a mounting bracket and a nozzle assembly; the mounting bracket is provided with multiple cantilever arms, which are arranged in parallel along the horizontal direction; each cantilever arm is correspondingly mounted with a nozzle assembly; the nozzle assembly includes a nozzle body for spraying high-pressure airflow, the nozzle body is lockably slidably disposed along the cantilever arm, and the nozzle body is controllably swingable along the horizontal and vertical directions.

[0007] Furthermore, the nozzle assembly also includes a sliding support, with the nozzle body mounted on the bottom surface of the sliding support, which is mounted on the cantilever in a lockable manner.

[0008] Furthermore, the nozzle assembly also includes a nozzle clamp, the nozzle body is clamped by the nozzle clamp, and a connecting ball head is provided on the bottom surface of the sliding support. The nozzle body is connected to the connecting ball head of the sliding support by means of a ball joint through the nozzle clamp.

[0009] Furthermore, the mounting bracket includes a suspension frame and support columns. The suspension frame is a "C"-shaped frame structure consisting of two parallel short rods and a long rod set between the short rods. The suspension frame is set horizontally, and vertical support columns are set at the ends of the two short rods of the suspension frame. The cantilever is fixedly connected to the long rod, and multiple cantilever is evenly set along the axial direction of the long rod between the two short rods.

[0010] Furthermore, the top surface of the sliding support is integrally formed with a sliding clamp piece, which has a snap-fit ​​groove. There are two sliding clamp pieces, which are symmetrically arranged with the slots of the snap-fit ​​groove facing each other. The sliding support is slidably installed on the cantilever by snapping the snap-fit ​​groove symmetrically onto the cantilever. The two sliding clamp pieces can be driven to approach each other and clamp the cantilever to lock and limit the sliding support.

[0011] Furthermore, the nozzle assembly also includes a locking cover. The top of the nozzle clamp is integrally formed with a columnar hinge seat. Multiple hinge clips are symmetrically arranged on the top surface of the hinge seat. The hinge seat is hinged to the connecting ball head through the multiple hinge clips. The locking cover is a radially closed annular structure. The inner wall of the locking cover is a conical structure with a smaller top and a larger bottom. The locking cover is fitted onto the radial outer surface of the top of the multiple hinge clips and is connected to the multiple hinge clips by threads. The locking cover can be twisted to move up and down. The multiple hinge clips are driven by the locking cover to move closer or further apart to lock or release the connecting ball head.

[0012] Furthermore, the nozzle clamp is an annular structure with an opening at the bottom. Clamping plates are respectively provided on both ends of the opening position of the nozzle clamp. The clamping plates can be manipulated to move closer to each other to lock the nozzle body, or the clamping plates can be manipulated to move further apart to release the nozzle body.

[0013] Furthermore, the mounting bracket also includes mounting feet, and mounting feet can be detachably installed on the bottom of any of the support columns.

[0014] Furthermore, the mounting bracket also includes a limiting plug, which can be detachably installed at the end of any cantilever. The limiting plug is coaxially arranged with the cantilever, and the diameter of the limiting plug is larger than the diameter of the cantilever, so as to limit the sliding of the nozzle assembly on the cantilever.

[0015] The beneficial effects of this technical solution are as follows:

[0016] The pneumatic actuator for label removal disclosed in this utility model features a sliding and multi-degree-of-freedom oscillating nozzle assembly design, which allows for flexible adjustment of the nozzle position to adapt to bottles of different shapes. The overall modular design allows for adaptation to label removal work on different production lines and for different products by adjusting the mounting position of the mounting bracket and the position and oscillation angle of the nozzle assembly. This effectively solves the problems of low label removal efficiency, poor adaptability, and insufficient stability in the prior art, and has the advantages of improving label removal efficiency and adapting to bottles of different materials and shapes.

[0027] The following detailed description illustrates the specific implementation method:

[0028] The reference numerals in the accompanying drawings include: nozzle assembly 1, mounting bracket 2, cantilever 3, nozzle body 4, limit plug 5, mounting foot 6, sliding support 7, nozzle clamp 8, locking cover 9, hinge seat 10, eccentric wheel locking device 11, sliding clamp 12, hinge clamp 13, snap-fit ​​groove 14, clamping plate 15, connecting ball head 16, support column 17, long rod 18, short rod 19.

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

[0030] The basic implementation examples are as follows: Figure 1-10 The illustration shows a pneumatic actuator for label rejection, comprising a mounting bracket 2 and a nozzle assembly 1. The mounting bracket 2 has multiple cantilever arms 3 arranged horizontally in parallel. Each cantilever arm 3 is fitted with a corresponding nozzle assembly 1. The nozzle assembly 1 includes a nozzle body 4 for spraying high-pressure airflow. The nozzle body 4 is lockably slidable along the cantilever arm 3 and can be manipulated to swing horizontally and vertically. The mounting bracket 2 can be welded from metal profiles, and the cantilever arms 3 are preferably cylindrical to reduce weight. The number of cantilever arms 3 can be set to 2-6 depending on the width of the production line; in this embodiment, it is set to 5, with each cantilever arm 3 fitted with one nozzle assembly 1, for a total of five nozzle assemblies 1. The nozzle body 4 can be made of stainless steel, and its air inlet can be equipped with a quick connector for connecting to an air source pipeline. The sliding mechanism can be implemented using a linear guide rail and locking bolts, and the swing mechanism can be implemented using a universal joint or ball joint structure, wherein the swing angle range of the ball joint structure should preferably be controlled within ±30°. The adjustable nozzle structure solves the problem of poor adaptability in existing label rejection equipment. The multi-cantilever layout forms a nozzle array that can cover bottle conveyor lines of different sizes. The three-dimensional adjustment function of the nozzles allows for precise alignment with labels on various bottle shapes. Compared to fixed nozzles, the sliding and swinging structure allows operators to quickly adjust the spray angle, significantly improving the equipment's adaptability to different bottle and label sizes. The high-pressure airflow spray method avoids bottle damage caused by mechanical contact. Furthermore, the modular design allows for easy adjustment of the number of cantilever 3s according to production line needs. As a preferred implementation, by adjusting the position and angle of the nozzle body 4, a ring array structure can be formed. This makes this execution module particularly suitable for handling irregularly shaped labels on curved bottles. Quick on-site adjustments allow for switching between different products, effectively improving the rejection rate.

[0031] In this embodiment, the nozzle assembly 1 further includes a sliding support 7. The nozzle body 4 is mounted on the bottom surface of the sliding support 7. The sliding support 7 is mounted on the cantilever 3 in a lockable manner. A sliding clamp 12 is integrally formed on the top surface of the sliding support 7. The sliding clamp 12 is provided with a snap-fit ​​groove 14. There are two sliding clamps 12, which are symmetrically arranged with the openings of the snap-fit ​​grooves 14 facing each other. The sliding support 7 is slidably mounted on the cantilever 3 in a manner where it is symmetrically snapped into the cantilever 3 by the snap-fit ​​grooves 14. The two sliding clamps 12 can be driven to approach each other and clamp the cantilever 3 to lock and limit the sliding support 7. The sliding clamp 12 can be made of metal or high-strength plastic. The cross-sectional shape of the snap-fit ​​groove 14 matches the outer contour of the cantilever 3. The two sliding clamps 12 are clamped by bolts or an eccentric wheel locking device 11. In this embodiment, the eccentric wheel locking device 11 is preferred. The eccentric wheel locking device 11 has the advantages of quick locking and easy operation, which is beneficial to the adjustment operation of the staff. As a preferred embodiment, the inner side of the sliding clamp 12 can be provided with anti-slip texture to enhance clamping stability. Thus, by setting the sliding support 7, the position of the nozzle body 4 on the cantilever 3 is adjustable, which is convenient for precise positioning according to the size of the wine bottle and the position of the label. Among them, the symmetrical snap-fit ​​structure ensures the smoothness of the sliding process, while the lockable design ensures the stability in the working state. This structure solves the problem of poor adaptability caused by the fixed nozzle position in the prior art. It achieves quick adjustment and reliable fixation through a simple mechanical structure, which significantly improves the compatibility of the equipment with different bottle types and label positions.

[0032] In this embodiment, the nozzle assembly 1 further includes a nozzle clamp 8 and a locking cover 9. The nozzle body 4 is clamped by the nozzle clamp 8. A connecting ball head 16 is provided on the bottom surface of the sliding support 7. The nozzle body 4 is connected to the connecting ball head 16 of the sliding support 7 via the nozzle clamp 8 in a ball-joint manner. The nozzle clamp 8 is an annular structure with an open bottom. Clamping plates 15 are respectively provided on both ends of the opening position of the nozzle clamp 8. The clamping plates 15 can be manipulated to move closer to each other to lock the nozzle body 4, or the clamping plates 15 can be manipulated to move away from each other to release the nozzle body 4. The top of the nozzle clamp 8 is integrally formed with a columnar hinge seat 10. Multiple hinge clips 13 are symmetrically arranged on the top surface of the hinge seat 10. The hinge seat 10 is hinged to the connecting ball head 16 through the multiple hinge clips 13. The locking cover 9 is a radially closed annular structure. The inner wall of the locking cover 9 is a conical structure with a smaller top and a larger bottom. The locking cover 9 is sleeved on the radial outer surface of the top of the multiple hinge clips 13 and is connected to the multiple hinge clips 13 by threads. The locking cover 9 can be twisted and moved up and down. The multiple hinge clips 13 are driven by the locking cover 9 to move closer or further away from each other to lock or release the connecting ball head 16.

[0033] Specifically, the conical inner wall design of the locking cover 9 allows it to exert radial pressure on the hinge clamp 13 when moving up and down. When the locking cover 9 moves downward, the conical inner wall forces the hinge clamp 13 to tighten inward, thereby clamping the connecting ball head 16 and locking it in place. Conversely, when the locking cover 9 moves upward, the hinge clamp 13 expands outward due to its elastic restoring force, releasing the constraint on the connecting ball head 16. Furthermore, the threaded connection between the locking cover 9 and the hinge clamp 13 can use fine-pitch threads to improve adjustment accuracy and locking stability.

[0034] The nozzle clamp 8 adopts a ring-shaped structure with an open bottom. The clamping plates 15 on both sides of the opening are opened and closed by mechanical drive or manual adjustment. As a preferred embodiment, the clamping plates 15 can be controlled by a threaded knob, a spring clamping mechanism, or a pneumatic drive. For example, in the threaded knob solution, the rotational movement of the knob can be converted into linear displacement of the clamping plates 15; in the pneumatic solution, the extension and retraction of the cylinder piston can drive the clamping plates 15 to move synchronously. In addition, anti-slip textures or elastic pads can be provided on the inner side of the clamping plates 15 to enhance clamping stability.

[0035] By employing a ball joint connection, the nozzle body 4 can be freely adjusted at multiple angles to accommodate the rejection needs of bottles of different shapes. Specifically, when adjusting the nozzle angle, first loosen the locking cap 9 to release the hinge clip 13 from the ball head 16. At this point, the horizontal and vertical angles of the nozzle body 4 can be manually adjusted. After adjustment, tighten the locking cap 9 to clamp the hinge clip 13 onto the ball head 16, thus fixing the angle. This structural design makes nozzle angle adjustment more flexible and convenient, while maintaining a stable working posture. Compared to traditional fixed nozzle structures, this solution significantly improves the equipment's adaptability to different bottle types and avoids the tedious operation of frequently changing nozzles.

[0036] In this embodiment, the mounting bracket 2 includes a suspension frame and support columns 17. The suspension frame is a "C"-shaped frame structure consisting of two parallel short rods 19 and a long rod 18 positioned between the short rods 19. The suspension frame is horizontally positioned, and vertical support columns 17 are provided at the ends of the two short rods 19. Cantilever arms 3 are fixedly connected to the long rod 18, and multiple cantilever arms 3 are evenly distributed along the axial direction of the long rod 18 between the two short rods 19. Specifically, the suspension frame adopts a "C"-shaped structure design, in which the two short rods 19 and the long rod 18 form a stable frame support. The support columns 17 are vertically fixed to the ends of the short rods 19 to provide vertical support for the overall structure. The cantilever arms 3 are evenly distributed along the axial direction of the long rod 18 to ensure the horizontal coverage of the nozzle assembly 1. In a preferred embodiment, the long rod 18 can be made of hollow square or round tubing to reduce weight while maintaining structural strength; the short rod 19 can be fixed to the long rod 18 by welding or bolting. Adjusting bolts can be installed at the bottom of the support column 17 for fine-tuning the levelness of the frame. The connection between the cantilever 3 and the long rod 18 can be achieved using flanges or U-shaped clamps for easy disassembly and maintenance. The "C"-shaped structure of the suspension frame in this embodiment ensures rigidity while providing ample installation space for the cantilever 3. The vertical connection between the support column 17 and the short rod 19 forms a stable triangular support system, effectively resisting vibrations caused by aerodynamic impacts.

[0037] In this embodiment, the mounting bracket 2 also includes mounting feet 6, and the bottom of any supporting column 17 is detachably fitted with a mounting foot 6. The mounting foot 6 serves as the bottom connecting component of the supporting column 17, and its detachable design allows for flexible adjustment according to actual installation requirements. The specific structural form of the mounting foot 6 can be matched to the production line structure, such as selecting... Figure 10 The plate-like structure shown can also be replaced with a clamp or similar device to facilitate the installation of the execution module onto the production line. By incorporating detachable mounting feet 6 at the bottom of the support column 17, the poor adaptability of existing label removal equipment due to its fixed installation method is resolved. The detachable design of the mounting feet 6 allows for rapid adjustment of the equipment according to different production line layouts or floor conditions without requiring a complete replacement of the support structure. Therefore, when changing bottle styles or adjusting production lines, only adaptive adjustments to the mounting feet 6 are needed to achieve rapid equipment adaptation, significantly improving the equipment's adaptability to different production environments. Compared to existing technologies, this solution achieves greater flexibility and convenience in equipment installation through simple structural improvements, effectively reducing the time and labor costs required for equipment adjustments.

[0038] In this embodiment, the mounting bracket 2 also includes a limiting plug 5. A limiting plug 5 can be detachably installed at the end of any cantilever 3. The limiting plug 5 is coaxially arranged with the cantilever 3, and its diameter is larger than that of the cantilever 3, thus limiting the sliding of the nozzle assembly 1 on the cantilever 3. Specifically, the limiting plug 5 can be fixed to the end of the cantilever 3 by a threaded connection or a snap-fit ​​connection; in this embodiment, a threaded connection is preferred. The limiting plug 5 is preferably made of engineering plastic or aluminum alloy, and its diameter is 5-10 mm larger than that of the cantilever 3 to ensure effective limiting. The detachable limiting plug 5 structure achieves mechanical limiting of the sliding stroke of the nozzle assembly 1. Specifically, when the nozzle assembly 1 slides along the cantilever 3 to the end, the large-diameter structure of the limiting plug 5 prevents the sliding support 7 from continuing to move, avoiding damage to the equipment caused by the nozzle assembly 1 slipping off the cantilever 3; and after the plug is removed, the nozzle assembly 1 can be easily removed.
