Description

Technical Field

[0001] This utility model relates to the field of packaging machinery and equipment technology, specifically to the structure of a spring and blade for a paper tube hot melt adhesive labeling machine. Background Technology

[0002] Currently, similar structures used in the labeling process of labeling machines on the market mainly have the following drawbacks:

[0003] Rigid compression easily produces indentations: Most methods use rigid, fixed metal sheets or excessively high-pressure structures for label pressing, lacking cushioning. This easily leaves unsightly indentations on the labels, and may even damage the label surface coating or paper fibers, severely affecting the high-end feel of the product. Highly prone to adhesive residue, requiring frequent maintenance: When pressing labels with undried adhesive, the adhesive is easily squeezed out and adheres to the surface of the pressing sheet (blade). Adhesive buildup leads to adhesive pulling and trailing, contaminating labels and equipment, requiring frequent shutdowns for cleaning, which is time-consuming, labor-intensive, and impacts production efficiency. Uneven pressure results in poor labeling: Traditional pressing methods struggle to ensure uniform pressure distribution on the pressing sheet contact surface, easily causing labels to lift due to insufficient pressure in certain areas (especially edges and joints), or to dent due to excessive pressure, resulting in low product yield. Poor adaptability: Different materials and adhesive properties require different ideal pressing forces and toughness; rigid structures cannot adaptively adjust, resulting in low versatility. To solve the above technical problems, we designed a structure for the spring and blade of a paper tube hot melt adhesive labeling machine. Utility Model Content

[0004] The purpose of this utility model is to provide a structure for the spring and blade of a paper tube hot melt adhesive labeling machine, which has the advantages of traceless labeling, uniform and firm adhesive application, non-stick blade, and aesthetic appeal and durability. It solves the problems of rigid pressing, indentation, easy adhesion, frequent maintenance, uneven pressure, poor labeling effect, and poor adaptability of the existing labeling machine's labeling process structure during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a structure for a spring and blade of a paper tube hot melt adhesive labeling machine, comprising two mounting plates arranged front to back. A spring component and a blade component are respectively mounted on the bottom and top of opposite sides of the two mounting plates. The spring component includes a stainless steel tube shaft one, the front and rear sides of which contact the bottom of opposite sides of the two mounting plates. The blade component includes a stainless steel tube shaft two, the front and rear sides of which contact the top of opposite sides of the two mounting plates. Several mounting slots are provided on the right side of the outer surface of the stainless steel tube shaft one. A mounting screw hole is provided at the center of the left side of the inner wall of each mounting slot. A spring is placed inside the mounting slot, and a mounting bolt is provided on the right side of the spring. Several isolation rings are slidably sleeved on the outer surface of the stainless steel tube shaft two, and a blade is slidably sleeved on the outer surface of the stainless steel tube shaft two, located between the front and rear isolation rings.

[0006] Preferably, the stainless steel tube shaft one is provided with positioning screw holes one on both the front and rear sides, the stainless steel tube shaft two is provided with positioning screw holes two on both the front and rear sides, and the top and bottom of the two mounting plates on the opposite side are provided with internal hexagon positioning bolts.

The left side of the mounting bolt passes through the spring sheet and is threadedly connected to the mounting screw hole. A through hole is provided on the left side of the inner wall of the mounting screw hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention, through the combined use of a mounting plate, blade components, and spring components, offers advantages such as residue-free labeling, uniform and firm adhesive application, non-stick blades, and aesthetic appeal while remaining durable. Residue-free labeling: Elastic pressure replaces rigid impact, effectively preventing indentations, scratches, or deformation on soft paper label surfaces, ensuring a smooth and even label appearance. Uniform and firm adhesive application: Gentle and constant pressure allows the adhesive to flow evenly and fully contact the paper tube surface, effectively eliminating air bubbles and curling edges, ensuring extremely firm labeling. Non-stick blades: The unique structural design and pressure control prevent excessive adhesive from being squeezed onto the blade surface, fundamentally solving the problem of adhesive contamination and ensuring the blade remains clean. Aesthetic appeal and durability: Not only does it greatly enhance the appearance of the labeled product, but it also improves production efficiency and stability by eliminating damage to the labeling paper caused by the blade.

[0017] Please see Figures 1-4A structure for a hot melt adhesive labeling machine for paper tubes, comprising two mounting plates 1 arranged front to back, with a spring component 3 and a blade component 2 mounted on the bottom and top of opposite sides of the two mounting plates 1, respectively. The spring component 3 includes a stainless steel tube shaft 33, the front and rear sides of which contact the bottom of opposite sides of the two mounting plates 1. The blade component 2 includes a stainless steel tube shaft 22, the front and rear sides of which contact the top of opposite sides of the two mounting plates 1. Several mounting slots 35 are provided on the right side of the outer surface of the stainless steel tube shaft 33. A mounting screw hole is provided at the center of the left side of the inner wall of each mounting slot 35. The interior of each mounting slot 35 contains... A spring clip 34 is provided, and a mounting bolt 32 is provided on the right side of the spring clip 34. Several isolation rings 23 are slidably sleeved on the outside of the stainless steel tube shaft 22. A blade 24 is slidably sleeved on the outside of the stainless steel tube shaft 22 and located between the front and rear isolation rings 23. The frontmost isolation ring 23 and the rearmost isolation ring 23 are in contact with the rear side of the front mounting plate 1 and the front side of the rear mounting plate 1, respectively. No blade 24 is placed between the frontmost isolation ring 23 and the next frontmost isolation ring 23, and there is no space for blade 24 to be placed between them. Similarly, no blade 24 is placed between the rearmost isolation ring 23 and the next rearmost isolation ring 23, and there is no space for blade 24 to be placed between them.

[0018] The stainless steel tube shaft 1 33 has positioning screw holes 1 31 on both the front and rear sides, and the stainless steel tube shaft 22 has positioning screw holes 21 on both the front and rear sides. The top and bottom of the two mounting plates 1 on the opposite side are provided with internal hexagon positioning bolts 4.

[0019] The two hexagon socket head cap screws 4 at the bottom each penetrate the two mounting plates 1 on opposite sides and extend into the interior of the first positioning screw hole 31, where they are threadedly connected. The two hexagon socket head cap screws 4 at the top each penetrate the two mounting plates 1 on opposite sides and extend into the interior of the second positioning screw hole 21, where they are threadedly connected. Through the engagement of the hexagon socket head cap screws 4 and the first positioning screw hole 31, as well as the engagement of the hexagon socket head cap screws 4 and the second positioning screw hole 21, stainless steel tube shaft 1 33 and stainless steel tube shaft 2 22 can be installed between the two mounting plates 1.

[0020] The mounting plate 1 has through holes 5 for use with hexagonal socket head cap screws 4, and all four corners of the mounting plate 1 are chamfered.

The spring 34 can be positioned by using the cooperation of the mounting screw hole and the mounting bolt 32.

[0022] In use, blade 24 is not for cutting; its core function is to press and smooth. During the labeling process, as the label wraps around the paper tube and reaches the joint, spring 34 applies a constant and gentle elastic pressure to blade 24, causing blade 24 to firmly press the end of the label (especially the overlap) onto the surface of the paper tube. This pressure continues throughout the labeling process, ensuring that the hot melt adhesive bonds fully, thus achieving perfect labeling. Furthermore, the advantages of this application are mainly reflected in the following aspects: Seamless labeling: Elastic pressure replaces rigid impact, effectively avoiding indentations, scratches, or deformation on soft paper label surfaces, ensuring a smooth and flat label appearance; Uniform and firm adhesive application: Gentle and constant pressure allows the adhesive on the label back to flow evenly and fully contact the paper tube surface, effectively eliminating air bubbles and curling edges, ensuring extremely firm labeling; Non-adhesive blade 24: The unique structural design and pressure control prevent excessive extrusion of adhesive onto the surface of blade 24, fundamentally solving the problem of adhesive contamination and ensuring that blade 24 remains clean; Aesthetically pleasing and durable: Not only greatly improving the aesthetics of the labeled product, but also improving production efficiency and stability by eliminating the damage to the labeling paper caused by blade 24; Furthermore, the purpose of this application is to: Fundamentally solve the adhesive problem: Through optimized elastic pressure application and contact surface treatment, ensure that blade 24 is not easily contaminated by adhesive while working effectively, achieving long-term maintenance-free operation. Ultimate in Labeling Appearance Quality: Utilizing the controllable elastic pressure provided by spring 34, a seamless, flat, and smooth labeling effect is achieved, maximizing the aesthetic appeal and market competitiveness of product packaging. Ensuring Uniform Adhesive and Firm Adhesion: Providing continuous, stable, and uniform linear pressure ensures a complete seal between the label, especially at the joints, and the paper tube surface, eliminating air bubbles and curling edges, thus enhancing label durability. Enhancing Equipment Versatility and Reliability: The labeling device intelligently adapts to labels of different materials and adhesive properties, reducing adjustments required when changing products and improving the automation level and overall efficiency of the production line.

[0023] In summary, the structure of the spring and blade of this paper tube hot melt adhesive labeling machine, through the coordinated use of mounting plate 1, blade component 2 and spring component 3, solves the problems of rigid pressing, easy indentation, easy glue adhesion, frequent maintenance, uneven pressure, poor labeling effect and poor adaptability of the existing labeling machine's labeling process structure.
