Description

Technical Field

[0001] This utility model relates to the field of adhesive paper rolls, and more particularly to an adhesive paper roll with a combined paper tube core. Background Technology

[0002] Paper is a thin sheet material made from plant fibers that have been purified and dispersed through physical and chemical treatment. Water is filtered through a porous mold to form a wet fiber layer, which is then dried and bonded together. It is commonly used for writing, printing, packaging, and cleaning, replacing traditional carriers such as bamboo slips and silk. Adhesive paper rolls are sticky, rolled cleaning tools, typically cylindrical, similar to a paint roller. They can easily and quickly remove contaminants and dust from surfaces, avoiding secondary pollution in cleanrooms. They are widely used in industries such as circuit boards, LCD displays, optoelectronics, semiconductors, and precision printing.

[0003] Existing technology CN210884717U specifically describes a dust-adhesive paper roll based on a combined paper tube core. The roll includes a tube composed of a core and a dust-adhesive film, with the length of the dust-adhesive film exceeding the length of the core. A plug is inserted at each end of the roll. In this invention, the plugs seal the ends of the roll, supporting the dust-adhesive film at the ends, preventing the film from collapsing and paper scraps from falling out during use, thereby improving the quality of the paper roll.

[0004] However, the aforementioned paper roll with adhesive core has the following problems: a plug is inserted at each end of the roll. The plug is made of plastic. The use of plastic material makes the paper roll environmentally unfriendly in the later processing. Moreover, during the rolling process, the design of the plug causes frequent friction on the inner wall of the plug, resulting in the shedding of plastic particles and debris.

[0005] Therefore, it is necessary to improve the aforementioned adhesive paper roll based on a combined paper tube core. Summary of the Invention

[0006] This invention overcomes the shortcomings of the prior art and provides a dust-adhesive paper roll with a combination of paper tube core.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a dust-adhesive paper roll with a combination of paper tube core, comprising: a paper tube body, a paper roll disposed on the paper tube body, and a PE coating disposed on the inner wall of the paper tube body;

[0008] A thin film is adhered to the PE coating. A support block is provided in the middle of the inner wall of the paper tube body. A paper tube core is provided on the support block. Several support heads are provided on the inner walls of both ends of the paper tube body. The thin film is adhered to the several support heads. The thin film is adhered to the inner wall of the paper tube core. A first through hole is opened through the center of the inside of the paper tube core. The gap between the support heads arranged vertically and vertically constitutes a second through hole.

[0009] In a preferred embodiment of this utility model, the inner core of the paper tube is rotatably sleeved on a plurality of fixed shafts, the diameter of the circular surface at both ends of the plurality of fixed shafts is 5mm less than the length of the inner cross section of the inner core of the paper tube, a rotating handle is provided at the top of the plurality of fixed shafts, and external threads are provided on the surface at the top of the plurality of fixed shafts.

[0010] In a preferred embodiment of this utility model, a plurality of fixed-axis threaded connections are provided with a plurality of limiting rings, and the plurality of limiting rings are provided with internal threads.

[0011] In a preferred embodiment of this utility model, a connecting member is provided on the outer surface of several of the limiting rings.

[0012] In a preferred embodiment of this invention, the film is made of polytetrafluoroethylene.

[0013] In a preferred embodiment of this utility model, a gripping handle is provided at the center of the bottom end of the connector.

[0014] In a preferred embodiment of this utility model, the grip handle is provided with four finger-shaped grooves.

[0015] In a preferred embodiment of this utility model, the finger-shaped groove is provided with a plurality of protrusions, and the protrusions are made of rubber.

[0016] In a preferred embodiment of this invention, the adhesive paper on the paper roll is in the form of diagonal strips.

[0017] In a preferred embodiment of this utility model, the gap between the inner core of the paper tube and the PE coating forms a concave cavity, and the gap between the support end cap and the PE coating forms a hollow cavity.

[0018] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0019] (1) The design of the finger-shaped groove in this utility model conforms to the ergonomic principle. The user's fingers can be naturally embedded in it, which can distribute the pressure on the hand, reduce the fatigue caused by holding for a long time, and enhance the user's comfort during operation. The finger-shaped groove allows the fingers to grip the handle more firmly. The rubber material protrusion has good elasticity and friction coefficient, which can form an effective anti-slip barrier between the fingers and the finger-shaped groove, further enhancing the friction between the hand and the gripping handle. Even if there is a small amount of oil or sweat on the hands, it can effectively prevent the fingers from sliding in the groove.

[0020] (2) In this utility model, the external thread at the top of the fixed shaft and the internal thread inside the limiting ring cooperate with each other. The fixed shaft is fixed on the limiting ring through the threaded connection. By rotating the handle and using the limiting ring, the user can quickly and conveniently install, unfold and replace the adhesive paper roll, reducing the operation time, especially in environments where the adhesive paper roll needs to be replaced frequently.

[0021] (3) In this utility model, the film can reduce the friction between the inner wall of the paper tube core and the fixed shaft when the dust-sticking paper roll roll is rolling. The fixed shaft extends into the first through hole. When rotating, it will only cause a certain amount of collapse and damage to the inner wall of the paper tube core. The film will protect the inner wall of the paper tube core. The debris and particles generated during rotation will fall into the concave cavity and the hollow cavity. Due to the design of the concave cavity and the hollow cavity, the debris and particles falling into the concave cavity and the hollow cavity are not easy to fall out of the dust-sticking paper roll.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] like Figures 1-4 As shown, a dust-adhesive paper roll with a combined paper tube core includes: a paper tube body 1, a paper roll 2 disposed on the paper tube body 1, and a PE coating 3 disposed on the inner wall of the paper tube body 1.

[0030] In this invention, a PE coating is provided on the inner wall of the paper tube body 1, which can effectively prevent external moisture and humidity from penetrating the inside of the paper tube, protecting the adhesive paper roll inside the paper tube from the effects of moisture, and avoiding problems such as performance degradation or mold growth of the adhesive paper 17 after it gets damp, thereby extending the service life of the adhesive paper roll and maintaining its cleaning effect. A thin film 4 is adhered to the PE coating 3. The thin film 4 has a smooth surface, which can reduce the friction between the inner core 6 of the paper tube and components such as the fixed shaft 10 during rotation or movement, making the rotation smoother and reducing energy loss. A support block 5 is provided in the middle of the inner wall of the paper tube body 1. A paper tube core 6 is provided on the paper tube body 1. Several support heads 7 are provided on the inner walls of both ends of the paper tube body 1. A thin film 4 is adhered to the support heads 7. A thin film 4 is adhered to the inner wall of the paper tube core 6. A first through hole 8 is provided through the center of the paper tube core 6. The first through hole 8 provided through the center of the paper tube core 6 can be used as the installation and positioning position of components such as the fixed shaft 10, and guide the assembly between the paper tube core 6 and the fixed shaft 10. The gap between the support heads 7 arranged vertically and vertically forms a second through hole 9. The inner cross-sectional length of the second through hole 9 is smaller than the inner cross-sectional length of the second through hole 9.

[0031] In this invention, the inner core 6 of the paper tube is rotatably sleeved on several fixed shafts 10, ensuring that the inner core 6 can rotate freely. The diameter of the two ends of the fixed shafts 10 is 5mm less than the length of the inner cross-section of the inner core 6, ensuring sufficient space between the inner core 6 and the fixed shafts 10, allowing the inner core 6 to rotate smoothly without causing wobbling or instability due to excessive gaps. A rotating handle 11 is provided at the top of each of the fixed shafts 10, and external threads are provided on the surface of the top of each of the fixed shafts 10. Several limiting rings 12 are threadedly connected to the fixed shafts 10, and internal threads are provided inside the limiting rings 12. The limiting ring 12 is fixed to the fixed shaft 10 by a threaded connection, which plays an axial limiting role on the paper tube body 1 and prevents the paper tube body 1 from axially displacing during rotation. The design of the rotating handle 11 provides users with a convenient means of operation, making the installation and replacement of the adhesive paper roll faster and simpler. Users do not need to use additional tools. They only need to rotate the rotating handle 11 to drive the fixed shaft 10 to rotate spirally on the limiting ring 12, and remove or tighten the fixed shaft 10 as needed, reducing operation time and labor intensity.

[0032] In this invention, a connector 13 is provided on the outer surface of several limiting rings 12. A grip handle 14 is provided at the center of the bottom end of the connector 13. Four finger-shaped grooves 15 are provided on the grip handle 14. Several protrusions 16 are provided on the finger-shaped grooves 15, and the protrusions 16 are made of rubber. The finger-shaped grooves 15 are ergonomically designed so that the fingers can be naturally embedded in them, distributing hand pressure and reducing fatigue caused by long-term operation. The rubber protrusions 16 increase the friction between the fingers and the grip handle 14, preventing the fingers from slipping during operation and improving the stability and reliability of the grip. It also ensures stable operation even when the hands are oily or sweaty. By gripping the grip handle 14, the operator can more accurately control the rotation speed of the paper tube core 6.

[0033] In this invention, the film 4 is made of polytetrafluoroethylene (PTFE). The PTFE film 4 has an extremely low coefficient of friction, which significantly reduces the friction between the paper tube core 6 and the fixed shaft 10 and other components, making the paper tube core 6 rotate more smoothly, reducing energy loss, and improving operating efficiency.

[0034] In this invention, the adhesive paper 17 on the paper roll 2 is in the shape of a diagonal strip. The diagonal strip design of the adhesive paper 17 makes it easier for the user to find the starting point for tearing, and makes tearing more convenient. The user can easily tear the adhesive paper 17 from one end of the diagonal strip.

[0035] In this invention, the gap between the inner core 6 of the paper tube and the PE coating 3 forms a recess 18, and the gap between the support end cap 7 and the PE coating 3 forms a cavity 19. The design of the recess 18 and the cavity 19 allows for a certain amount of space inside the paper tube body 1, reducing the solid portion of the paper tube body 1 and thus reducing the amount of material used. The recess 18 and the cavity 19 can provide a certain buffering effect when the paper tube is subjected to external impact or compression, reducing the direct impact of external force on the internal structure of the paper tube body 1. During the use of the adhesive paper roll, some tiny debris, particles, or dust may fall off the adhesive paper 17. The recess 18 and the cavity 19 can effectively collect these debris and particles, preventing them from falling into the external environment and avoiding secondary pollution to the clean area.

[0036] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
