Description

Technical Field

[0001] This utility model relates to the technical field of heat-shrinkable folded double-layer film packaging for products, specifically a sticky note applicator for heat-shrinkable folded double-layer film packaging. Background Technology

[0002] Heat-shrinkable double-layer film is widely used in product packaging due to its excellent sealing and protective properties. This packaging method effectively protects goods from damage during transportation and storage, thereby extending shelf life and enhancing overall quality. However, as consumers increasingly demand convenience and security in packaging, heat-shrinkable double-layer film packaging faces new challenges in terms of easy-tear opening and label application.

[0003] Current Status and Problems of the Industry

[0004] The challenge of handling easy-tear edges:

[0005] Traditional heat-shrink double-layer film packaging is often difficult for consumers to open easily, requiring tools such as utility knives, scissors, or sharp needles. This not only increases the difficulty and time cost of operation but also poses a potential safety hazard due to improper handling, potentially causing personal injury.

[0006] The inconvenience of easy-tear openings severely impacts the user experience, especially in emergency situations or for special groups such as children and the elderly, where this packaging method is even more inconvenient.

[0007] Limitations of traditional solutions:

[0008] To address the issue of easy-tear openings, some manufacturers have attempted to unfold double-layered films into single-layered films to create easy-tear openings, and then reassemble them into double-layered films. However, this method significantly increases the complexity of equipment operation, requiring additional steps such as unfolding, punching, pasting, and refolding, leading to reduced production efficiency.

[0009] At the same time, this method also occupies more production space, making it difficult to adjust the production line layout, which is an important consideration for companies with limited space.

[0010] Analysis of existing technologies:

[0011] While existing heat-shrinkable double-layer film packaging equipment can achieve efficient packaging operations, it still has shortcomings in handling easy-tear openings. Traditional perforation methods rely on manual or simple mechanical devices, which are prone to problems such as inaccurate perforation positions and inconsistent sizes, affecting the subsequent user experience.

[0012] There are also problems with the way labels are applied. It is often impossible to ensure that the label is precisely aligned with the tear strip, which may cause the label to be crooked or fall off, thereby reducing user satisfaction. Utility Model Content

[0080] This invention relates to a label pasting device for heat-shrinkable folded double-layer film packaging, aiming to simplify the handling steps for easy-tear openings in existing heat-shrinkable film packaging processes and improve operational safety and efficiency. The device consists of a mechanism platform, an easy-tear opening punching component, a label supply device, and a label pasting device. These components work together to achieve efficient processing of heat-shrinkable folded double-layer film.

[0081] Easy-tear perforation: The servo motor 3 drives the reducer 4 to rotate the perforation shaft 6, so that the perforation shaft 6 is located between the double-layer film, and completes precise perforation in conjunction with the perforation device 5 fixed above.

[0082] Sticky label application: After the label tape is led out from the label tray 18, it passes through a series of guiding components (such as the label shaft 21, the rewind wheel, etc.) and finally combines with the perforated heat shrink film at the label knife 14. Then it returns to the film feeding system of the heat shrink machine through the film feeding shaft 17 to continue the subsequent processes.

[0083] Label supply: The entire roll of labels is placed on the label tray 18. The labels are gradually released as the label tape moves. The label tape after use is recycled to the recycling tray 19.

[0084] Working principles of various preferred technical solutions

[0085] Label reversing roller setup: To ensure that the label tape can be smoothly transported and pasted in the correct position, a design with two reversing rollers (reversing roller 10 and reversing roller 21) is adopted to form a 90° path transition, ensuring stable contact between the label tape and the heat shrink film.

[0086] Linear guide rail 8 and sliding installation: To accommodate label tapes of different widths or thicknesses, the label base 16 is equipped with a label support 9 at the bottom, which can slide and adjust its position along the track fixed on the linear guide rail 8, while locking the current position with bolts, thus enhancing the flexibility and adaptability of the equipment.

[0088] The drilling device 5 is fixed by a mounting block on its top, which is securely fixed to the fixed crossbeam 12 by bolts, ensuring stability during the drilling process and avoiding errors caused by vibration and other factors.

[0089] Bottom shaft positioning seat 7 design: The bottom shaft positioning seat 7 is introduced to support the drilling bottom shaft 6 and is connected by bearings, so that the drilling bottom shaft 6 can maintain stable operation when rotating, further improving the drilling accuracy.

[0090] Detailed Workflow

[0091] Initial preparation: Install the mechanism platform module group of this utility model onto the existing heat shrink film packaging equipment, ensuring that each functional unit is correctly positioned and does not affect the original process flow.

[0092] Membrane material introduction: After the heat shrink film comes out of the film feeding system, it enters the easy-tear perforation component area of ​​this device. At this time, the film material will naturally be divided into upper and lower layers under the action of the perforation bottom shaft 6, with the perforation bottom shaft 6 located between these two layers of film.

[0093] Drilling operation: Start the servo motor 3, which drives the drill bottom shaft 6 to rotate via the reducer 4. At the same time, the drilling device 5 located above aligns with the drill bottom shaft 6 according to the preset parameters to perform the drilling operation, ensuring that the position and size of each tear-off opening are consistent.

[0094] Preparation before labeling: The label tape starts from the label reel 18, passes through the label shaft 21 and the rewind wheel 10 in sequence, and arrives near the label knife 14 to wait for the next operation; at the same time, the other end of the label tape is connected to the recovery wheel 22 through the return shaft 20, ready to receive the completed label tape back to the recovery reel 19.

[0095] Labeling: When the perforated heat shrink film moves to the label blade 14 position, the label tape adheres to it here, forming a complete label with an easy-tear indication. The label tape then continues to return along the original path and is sent into the recycling tray 19 through the recycling wheel 22.

[0096] Finished product output: Finally, the film with the labels attached returns to the film feeding system of the heat shrink machine via the film feeding shaft 17, and the final packaging of the product is completed according to the existing process.

[0097] Drive control: All of the moving parts mentioned above (such as rewind pulley 10, rewind pulley 21, gauge shaft 21, return shaft 20, take-up pulley 22, and film feeding shaft 17) can be equipped with independent motors for precise drive to ensure the automation and smoothness of the entire process.

[0098] 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.
