During the process of pushing the scraper along the cover to be pasted, the release paper and the film body are automatically separated, and the film body is simultaneously scraped and pasted. Thus, the problem of book wrapping film deformation, wrinkling and air bubble caused by uneven stress on both sides in traditional manual pasting is effectively solved.

Description

Technical Field

[0001] This utility model relates to the field of stationery technology, and in particular to an auxiliary tool for applying book cover film. Background Technology

[0002] Book cover film is a thin film material used to protect the cover of books. Applying a book cover film primarily protects the cover from wear, stains, and other damage, extending the book's lifespan, and also makes the book look cleaner and more aesthetically pleasing.

[0003] In the usual process of applying a book cover, the procedure is to first tear off the backing paper of the book cover. While tearing off the backing paper, a tool similar to a scraper is used to push the scraper along the surface of the book so that the book cover is gradually adhered to the cover.

[0004] However, during the process of tearing off the backing paper, it is difficult to ensure even force on both sides by manual operation, which can easily lead to uneven pulling on both sides. Once uneven pulling occurs, the book cover film will deform, resulting in wrinkles and air bubbles on the cover. This not only affects the appearance of the book but may also reduce the protective effect on the cover due to the book cover film not adhering tightly. Utility Model Content

[0005] The purpose of this utility model is to provide an auxiliary tool for applying book wrapping film, so as to solve the technical problem that the conventional book wrapping film application method in the prior art is not easy to operate and easily leads to poor film application effect.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A book cover film application tool is used to attach book cover film to the cover of a book. The book cover film includes a film body and a release paper adhesively bonded to the film body. The book cover film application tool includes:

[0008] A scraper with a flattening edge for contacting the cover to be applied;

[0009] A clamping structure is disposed on the scraper, and the clamping structure and the scraper together define a clamping space with the opening facing the scraped edge, the clamping space being used to clamp the book wrapping film;

[0010] When the scraper is pushed along a direction parallel to the cover to be applied, the clamping structure can prevent the release paper from moving with the film, so that the release paper is separated from the film. At the same time, the scraping edge presses the separated film tightly against the cover to be applied.

[0011] Preferably, the clamping structure includes two clamping arms arranged facing each other, the clamping arms being fixedly connected to both sides of the scraper by a support portion, and an avoidance gap being formed between the two clamping arms.

[0012] Preferably, the clamping structure is movably connected to the scraper, and the clamping structure has an open position and a closed position. In the closed position, the clamping structure and the scraper together form the clamping space.

[0013] Preferably, the clamping structure includes two rotatably connected movable arms disposed opposite to each other on both sides of the scraper, and a clamping baffle is disposed between the two movable arms. The movable arms are rotatable relative to the scraper so that the clamping baffle switches between the open position and the closed position.

[0014] Preferably, the scraper is provided with positioning blocks on both sides and the movable arm is provided with positioning grooves, so that the positioning blocks can be engaged with the positioning grooves when the scraper is in the closed position.

[0015] Preferably, the clamping structure includes two mounting positions disposed opposite to both sides of the scraper and an elastic clamping strip disposed between the two mounting positions. Each end of the elastic clamping strip is connected to one of the mounting positions, and the clamping space is formed between the elastic clamping strip and the scraper. The elastic clamping strip can generate elastic deformation to change the size of the clamping space.

[0016] Preferably, at least one end of the elastic clamping bar is detachably connected to the corresponding mounting position.

[0017] Preferably, when the scraping edge contacts the cover to be applied and is in the scraping working state, the scraper and the cover to be applied are set at an angle, wherein the angle is greater than or equal to 0 degrees and less than or equal to 45 degrees.

[0018] Preferably, the scraper has a limiting protrusion on at least one sidewall corresponding to the clamping space, extending in a direction of movement parallel to the scraping edge.

[0019] Preferably, the scraper has a gripping part on the side opposite to the scraping edge.

[0020] The beneficial effects of this utility model are:

[0021] This utility model proposes a book wrapping film application aid tool. Through the coordinated operation of a scraper and a clamping structure, it achieves automatic separation of the release paper and the film body, as well as simultaneous smoothing and bonding of the film body, while pushing the scraper along the cover to be covered. This effectively solves the problems of deformation, wrinkling, and air bubbles in traditional manual film application caused by uneven force on both sides. Specifically, the clamping structure is set on the scraper and together with the scraper forms a clamping space with an opening facing the smoothing edge. The clamping structure can stably clamp the book wrapping film, so that when the scraper is pushed, the release paper in the clamping space is blocked and cannot move with the film body, forcing the release paper and film body to separate gradually and smoothly during the scraper's movement. At the same time, the smoothing edge of the scraper moves closely against the cover to be covered, continuously pressing and unfolding the separated film body onto the cover to be covered, ensuring that the film body is smoothed and firmly bonded the moment it is separated from the release paper, avoiding wrinkles and air bubbles caused by manual pulling or misalignment. The entire film application process requires only one-way pushing of the tool to simultaneously peel off the release paper and apply the film, which not only reduces the difficulty of operation and improves the efficiency of film application, but also allows the book cover film to be evenly and smoothly covered on the cover to be applied.

[0033] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] See Figure 1 and Figure 2The book wrapping film application tool provided in this embodiment is used to attach the book wrapping film 200 to the cover 101 of a book 100. The book wrapping film 200 includes a film body and a release paper bonded to the film body. When the book wrapping film 200 is unfolded and laid flat, the release paper in the middle area of ​​the book wrapping film 200 can be torn off first, thereby exposing the adhesive film body underneath. This allows the user to align the spine of the book 100 and stick it onto the exposed film body, achieving initial positioning of the book 100. After the spine is reliably fixed, the user can use the book wrapping film application tool of this invention to smooth and apply the book wrapping film 200 to one of the covers 101 (e.g., the front cover) of the book 100 along the direction from the book edge towards the spine. After the cover 101 to be applied on one side is completely and flat, the same procedure is followed to apply the book wrapping film 200 to the cover 101 to be applied on the other side of the book 100 (e.g., the back cover), thereby completing the entire book cover wrapping process.

[0035] Specifically, the book wrapping film application tool includes a scraper 1 and a clamping structure 2. The scraper 1 has a flattened edge 11 for contacting the cover 101 to be covered; the clamping structure 2 is disposed on the scraper 1, and the clamping structure 2 and the scraper 1 together define a clamping space 20 with an opening facing the flattened edge 11. The clamping space 20 is used to clamp the book wrapping film 200. When the scraper 1 is pushed in a direction parallel to the cover 101 to be covered, the clamping structure 2 can prevent the release paper from moving with the film, so that the release paper is separated from the film. At the same time, the flattened edge 11 presses the separated film tightly against the cover 101 to be covered.

[0036] The book wrapping film application aid proposed in this utility model, through the coordinated cooperation of the scraper 1 and the clamping structure 2, can achieve automatic separation of the release paper and the film body and synchronous smoothing and bonding of the film body while pushing the scraper 1 along the cover 101 to be covered. This effectively solves the problems of deformation, wrinkling and air bubbles of the book wrapping film 200 caused by uneven force on both sides in traditional manual film application. Specifically, the clamping structure 2 is set on the scraper 1 and together with the scraper 1 forms a clamping space 20 with an opening facing the smoothing edge 11. The clamping structure 2 can stably clamp the book wrapping film 200, so that when the scraper 1 is pushed, the release paper in the clamping space 20 is blocked and cannot move with the film body, forcing the release paper and the film body to separate gradually and smoothly during the movement of the scraper 1. At the same time, the scraping edge 11 of the scraper 1 moves closely against the cover 101 to be covered, continuously pressing and unfolding the separated film onto the cover 101. This ensures that the film is scraped flat and firmly adhered the moment it detaches from the release paper, avoiding wrinkles and air bubbles caused by manual pulling or misalignment. Throughout the entire film application process, the user only needs to push the tool in one direction to simultaneously complete the release paper peeling and film application, which not only reduces the difficulty of operation and improves the efficiency of film application, but also allows the book cover film 200 to cover the cover 101 evenly and flatly.

[0037] The working principle and specific structure of the book wrapping film application aid (hereinafter referred to as the aid) will be explained in detail below.

[0038] The main body of the scraper 1 is a plate-shaped structure. The scraper 1 is provided with a flattening edge 11 for contacting and flattening the cover 101 to be applied. The lateral cross-sectional shape of the flattening edge 11 is a gradually narrowing wedge-shaped structure, that is, the thickness of the flattening edge 11 gradually decreases as you get closer to the flattening edge 11, so as to reduce the pushing resistance.

[0039] Furthermore, the outermost edge of the flattened edge 11 is a curved surface, which ensures that when the flattened edge 11 contacts and scrapes the film with a certain pressure, it cuts or scratches the film or book 100, thereby protecting the integrity of the film while ensuring effective removal of air bubbles and compaction.

[0040] Specifically, when the scraper edge 11 contacts the cover 101 to be applied and is in the scraping working state, the scraper 1 and the cover 101 are set at an angle, wherein the angle is greater than or equal to 0 degrees and less than or equal to 45 degrees. When the angle is close to 0 degrees, the scraper 1 is almost flat against the cover, which is suitable for initial positioning or application to warped books 100; as the angle increases to within 45 degrees, the user can apply uniform downward pressure to the film with less effort when pushing the scraper 1, which helps to smoothly expel air under the film. At the same time, this angle ensures that the scraper edge 11 can always effectively press the leading edge of the film, preventing it from lifting or creating new wrinkles during the application process, thereby making the peeling and application process smoother and more stable.

[0041] To further enhance the stability of the auxiliary tool during operation and its guiding effect on the book wrapping film 200, the scraper 1 is provided with a limiting protrusion 12 extending in the moving direction parallel to the scraping edge 11 on at least one side wall corresponding to the clamping space 20. When the book wrapping film 200 is placed into the clamping space 20, the limiting protrusion 12 can physically limit the book wrapping film 200 from at least one side, effectively preventing it from shifting laterally or twisting during the advancement process, ensuring that the book wrapping film 200 always moves synchronously with the scraper 1 along a predetermined straight path, thereby ensuring the straightness and accuracy of release paper peeling and film bonding.

[0042] Specifically, a grip 13 is provided on the side of the scraper 1 opposite to the scraping edge 11. The grip 13 can be a raised structure integrally formed with the scraper 1 or an additional handle, and the shape of the grip 13 is suitable for one-handed use. The grip 13 allows the user to hold the entire tool firmly and apply precise and even force when pushing the scraper 1, avoiding the scraper 1 from shaking due to an unstable grip.

[0043] Preferably, the vertical cross-section of the scraper 1 from the flattening edge 11 to the grip 13 is a continuously changing streamlined curved surface. Starting from the flattening edge 11, the streamlined surface extends gently upwards and backwards, providing a suitable initial angle for operation. It then smoothly transitions and gradually rises upwards, finally connecting naturally to the grip 13. This ergonomic continuous curved surface design allows the user's wrist to maintain a more natural and comfortable angle when holding the grip 13, effectively reducing fatigue during prolonged or frequent film application. Furthermore, the transition structure of the streamlined curved surface can more efficiently and smoothly transmit the pushing force applied by the user's hand to the flattening edge 11, avoiding sudden changes or forks in force and ensuring the dynamic stability of the scraper 1 during the application process.

[0044] It is understood that the specific form of the streamlined surface described above can be designed in various ways according to actual usage requirements and production processes. For example, the streamlined surface can be a continuous, smooth curve with uniform curvature, or it can be a composite surface composed of multiple curves with different curvatures smoothly connected. The specific form of the streamlined surface in this utility model is not limited here.

[0045] In a preferred embodiment of the present invention, the clamping structure 2 includes two clamping arms 21 arranged in opposite directions. The clamping arms 21 are fixedly connected to both sides of the scraper 1 by a support part 22, and an avoidance gap 23 is formed between the two clamping arms 21.

[0046] Its working principle is as follows: When the book cover 200 to be applied is unfolded, the folded edge of the bottom cover is not yet folded, causing the overall width of the book cover 200 from the book's foreground to be greater than the overall width from the spine. However, to ensure stability during application, the width of the clamping space 20 defined by the two clamping arms 21 is usually designed to be approximately the same as the width of the book 100, i.e., the width of the spine. If the auxiliary tool is directly slipped onto the book cover 200, the clamping arms 21 will not be able to slip in smoothly because the widest part of the book cover 200 is wider than the clamping space 20.

[0047] Therefore, when using the book cover 200, firstly, clamp one edge of the book cover 200 in the width direction onto one of the clamping arms 21; then, move the auxiliary tool horizontally so that the other edge of the book cover 200 in the width direction can slide obliquely into the clearance notch 23 formed between the two clamping arms 21, and finally be successfully clamped onto the other clamping arm 21.

[0048] Example 2

[0049] Figure 3 Embodiment 2 is shown, wherein components that are the same as or corresponding to those in Embodiment 1 are represented by the same reference numerals as those in Embodiment 1. For simplicity, only the differences between Embodiment 2 and Embodiment 1 are described. The differences are as follows:

[0050] The clamping structure 2 is movably connected to the scraper 1. The clamping structure 2 has an open position and a closed position. In the closed position, the clamping structure 2 and the scraper 1 together form the clamping space 20. The movable connection design makes the operation of clamping the book wrapping film 200 more flexible and convenient.

[0051] Specifically, the clamping structure 2 includes two rotatably connected movable arms 24 that are disposed opposite to each other on both sides of the scraper 1. A clamping baffle 25 is disposed between the two movable arms 24. The movable arms 24 can rotate relative to the scraper 1 so that the clamping baffle 25 can switch between an open position and a closed position.

[0052] When in the open position, the movable arm 24 rotates outward, causing the clamping baffle 25 to move away from the scraper 1, so that the user can place the starting end of the book wrapping film 200 on the appropriate position of the scraper 1. Subsequently, when the movable arm 24 is rotated inward to the closed position, the clamping baffle 25 and the scraper 1 approach each other and together form a clamping space 20, thereby clamping the end of the book wrapping film 200 within the clamping space 20, thus realizing the quick installation and fixation of the book wrapping film 200.

[0053] To ensure the stability and reliability of the clamping structure 2 during the smoothing and bonding process, positioning blocks 14 are provided on both sides of the scraper 1, and positioning grooves 241 are provided on the movable arm 24. In the closed position, the positioning blocks 14 can engage with the positioning grooves 241. When the movable arm 24 rotates to the closed position, the positioning blocks 14 engage with the positioning grooves 241 to form a mechanical interlock, thereby effectively locking the movable arm 24 when the scraper 1 moves forward, preventing the clamping baffle 25 from loosening on its own during operation, and ensuring the continuity and stability of the entire film application process.

[0054] Example 3

[0055] Figure 4 Embodiment 3 is shown, wherein components that are the same as or corresponding to those in Embodiment 1 are represented by the same reference numerals as those in Embodiment 1. For simplicity, only the differences between Embodiment 3 and Embodiment 1 are described. The differences are as follows:

[0056] The clamping structure 2 includes two mounting positions 15 disposed opposite to each other on both sides of the scraper 1 and an elastic clamping strip 26 disposed between the two mounting positions 15. Each end of the elastic clamping strip 26 is connected to a mounting position 15. A clamping space 20 is formed between the elastic clamping strip 26 and the scraper 1. The elastic clamping strip 26 can produce elastic deformation to change the size of the clamping space 20.

[0057] When the user inserts the end of the book wrapping film 200 into the clamping space 20 from the side, the elastic clamping strip 26 will elastically bend and deform outward under pressure, thereby temporarily widening the entrance of the clamping space 20 to facilitate the smooth insertion of the book wrapping film 200. After the book wrapping film 200 is in place, the elastic clamping strip 26 will rebound inward and continuously press against the surface of the book wrapping film 200 due to the elastic restoring force of its material, thereby stably constraining it on the scraper 1. This allows the clamping structure 2 to automatically adapt to book wrapping films 200 of different thicknesses or slightly extra-wide sizes, improving the adaptability of the auxiliary tool.

[0058] Furthermore, at least one end of the elastic clamping strip 26 is detachably connected to the corresponding mounting position 15. When it is necessary to clamp the book wrapping film 200, the user can first remove one or both ends of the elastic clamping strip 26 from the mounting position 15, so that the clamping space 20 is fully open. At this time, the user places the end of the book wrapping film 200 in the predetermined position on the scraper 1, ensuring that it is placed correctly, avoiding possible positional displacement or film curling that may occur if it is forcibly inserted under the tension of the elastic clamping strip 26. After the book wrapping film 200 is properly placed, the elastic clamping strip 26 is reinstalled on the mounting position 15 to restore the clamping function.

[0059] The detachable connection between at least one end of the elastic clamping strip 26 and the corresponding mounting position 15 can be achieved through various means such as buckles, hooks or screws, which will not be elaborated here.

[0060] It is understood that the specific structure of the mounting position 15 is designed to form a detachable connection with the end of the elastic clamping strip 26. For example, if the end of the elastic clamping strip 26 is configured as a hook, a hook hole for accommodating and hooking the hook will be provided on the corresponding mounting position 15; similarly, if the end of the elastic clamping strip 26 is designed in other forms, such as a spherical end, a snap-fit ​​structure, or a pin, the mounting position 15 will also be provided with a matching structure such as a slot, recess, or insertion hole that can cooperate with it. The specific connection structure of the mounting position 15 is not limited here.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
