Description

Technical Field

[0001] This application relates to the field of office supplies technology, and more specifically to a laminating machine. Background Technology

[0002] A laminating machine, also known as a sealing machine, works by placing items such as documents and pictures in the center of a laminating film. The machine then uses the high temperature and pressure of its rollers to press the film together. Lamination is highly effective at protecting paper, allowing photos and drawings to be preserved for a long time. After lamination, documents or photos need to be cut and punched before storage or use. However, most existing laminating machines have fixed paper cutting components. These fixed components are mounted on the laminating machine, causing the top of the machine to protrude, resulting in large packaging and wasted space. Another option is to configure the paper cutting component separately on the laminating machine. In this case, the paper cutting component lacks a dedicated storage space after use and can be placed haphazardly, easily leading to damage or loss. Therefore, to address the aforementioned issues, a utility model patent with authorization announcement number CN218876695U discloses an integrated gluing machine, including a gluing machine body, a paper cutter, a corner rounder, a hole puncher, and a ring buckle. The top of the gluing machine body has a storage space, and a first groove, a second groove, a third groove, and a fourth groove are set in the storage space. The corner rounder is placed in the first groove, the hole puncher is placed in the second groove, the ring buckle is placed in the third groove, and the paper cutter is placed in the fourth groove. In this technical solution, by opening a storage space on the top of the gluing machine body and setting a first groove, a second groove, a third groove, and a fourth groove in the storage space, the corner rounder, the hole puncher, the ring buckle, and the paper cutter are placed in the first groove, the second groove, the third groove, and the fourth groove respectively, thereby achieving storage. However, this storage method is relatively cumbersome. Users need to confirm the storage position of each tool in advance, and disassembly and assembly are required every time they are used. After the tools are taken out, they cannot be reinstalled in one go, and reinstallation is prone to errors, resulting in many inconveniences in use. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a laminator with a receiving cavity on the machine base that is adapted to the sliding path of the paper cutter. The receiving cavity can not only accommodate the flipped paper cutting component, but also the paper cutter can be stored in the receiving cavity after sliding to any position on the mounting base. The user does not need to confirm the storage position of the paper cutter in advance, and the disassembly and assembly are simple and labor-saving.

[0004] This application provides a laminating machine, including a base and a paper cutting assembly. The paper cutting assembly is detachably mounted on the base. The base has a receiving cavity adapted to the paper cutting assembly. After being detached from the base, the paper cutting assembly can be flipped and stored in the receiving cavity. The paper cutting assembly includes a paper cutter and a mounting base. The paper cutter is slidably mounted on the mounting base. The length of the receiving cavity is adapted to the sliding path of the paper cutter to accommodate the paper cutter at any position. In this technical solution, the paper cutting assembly includes a paper cutter and a mounting base. Considering that mounting the paper cutting assembly on the base would cause the top of the base to protrude, resulting in a larger storage space, the paper cutting assembly is detachably connected to the base. The base has a receiving cavity to accommodate the paper cutting assembly. After use, the paper cutting assembly can be detached from the base and then flipped to be stored in the receiving cavity, thus hiding the paper cutter in the receiving cavity. This fully utilizes the internal space of the base and helps to reduce the overall size of the machine. The paper cutter is slidably mounted. On the mounting base, the paper cutter slides to cut documents at different positions, meeting more usage needs. Therefore, the position of the paper cutter on the mounting base is not fixed. By setting the length of the receiving cavity to match the sliding path of the paper cutter, the range of movement of the paper cutter during use is fully considered. This ensures that no matter where the paper cutter slides on the mounting base, it can be completely stored in the receiving cavity by flipping. Users do not need to confirm the storage position of the paper cutter in advance, improving the convenience and comfort of use. Moreover, the disassembly and assembly of the paper cutting component is easier and less effort.

[0005] As an improvement, the mounting base is movably connected to the receiving cavity. When force is applied, one end of the mounting base detaches from the receiving cavity, allowing it to slide and flip relative to the cavity. Flipping the mounting base allows the paper cutter to be stored within the receiving cavity and close it. In this technical solution, the mounting base is movably connected to the receiving cavity, enabling it to partially detach from the cavity under force to gain movement space. The user applies force to the mounting base, causing one end to detach from the cavity, and the movement of the mounting base is unrestricted. This ensures that the mounting base completely conceals the opening of the receiving cavity when installed, and also allows the mounting base to slide and flip relative to the cavity. This enables effective flipping and storage of the mounting base even in space-constrained situations, reducing the overall storage size of the machine, resulting in a more rational space distribution, and making the disassembly and assembly of the paper cutting assembly easier and less strenuous.

[0006] As an improvement, the inner wall of the accommodating cavity is provided with a first slide rail, and the side wall of the mounting base is provided with a first rotating shaft adapted to the first slide rail. The first rotating shaft is connected to the first slide rail, allowing the mounting base to slide and rotate relative to the accommodating cavity. In this technical solution, by providing a first slide rail inside the accommodating cavity and a first rotating shaft on the mounting base, and connecting the first rotating shaft to the first slide rail, the mounting base can slide relative to the accommodating cavity, and the mounting base can rotate relative to the accommodating cavity via the first rotating shaft. The structural design is ingenious and reliable, which helps to improve space utilization and is convenient and labor-saving to use.

[0007] As an improvement, the first rotating shaft is disposed on the side wall of one end of the mounting base. The first rotating shaft cooperates with the first slide rail to confine one end of the mounting base within the receiving cavity. In this technical solution, by disposing of the first rotating shaft at the end of the mounting base, one end of the mounting base remains connected to the receiving cavity at all times, and this end of the mounting base can slide and rotate via the first rotating shaft. This results in better overall stability and more reliable use. The user only needs to apply force to the other end of the mounting base to disengage it from the receiving cavity, allowing the mounting base to have room to slide and rotate. The structural design is more ingenious and reliable.

[0008] As an improvement, two first slide rails are symmetrically arranged on the inner wall of the accommodating cavity, and two first rotating shafts are symmetrically arranged on the side wall of the mounting base. In this technical solution, two first slide rails are symmetrically arranged on the inner wall of the accommodating cavity, and the two first slide rails are respectively located on both sides of the mounting base. First rotating shafts corresponding to the first slide rails are respectively arranged on the side walls of the mounting base. The two first rotating shafts correspond one-to-one with the two first slide rails, providing dual-point support for the mounting base. This support method improves the stability of the structure, reduces the tilting or imbalance that may be caused by single-point support, helps to maintain the balance of the mounting base during sliding and flipping, and improves storage efficiency.

[0009] As an improvement, the mounting base is provided with a base plate, which is a planar structure. When the mounting base flips open to close the receiving cavity, the base plate is flush with the surface of the machine base. In this technical solution, the planar structure of the base plate of the mounting base ensures that when the mounting base flips open to close the receiving cavity, the base plate can form a flat surface with the surface of the machine base. This allows the paper cutting assembly to be better housed in the base, resulting in a better visual appearance and reducing the overall storage size of the machine.

[0010] As an improvement, one end of the receiving cavity is provided with a receiving groove adapted to the paper cutter. When the paper cutter slides away from the receiving groove to the end of the mounting base, the mounting base slides and flips relative to the receiving cavity to house the paper cutter in the receiving groove. In this technical solution, the paper cutter is slidably mounted on the mounting base, and the paper cutter protrudes relative to the mounting base. By providing a receiving groove in the receiving cavity specifically for housing the paper cutter, the paper cutter is prevented from sliding back and forth in the receiving cavity. The receiving groove limits and houses the paper cutter, improving the stability of housing and preventing the paper cutter from being damaged by collision. Furthermore, the receiving groove is located at the end of the receiving cavity, and the receiving groove is opposite to the flipped end of the mounting base. When it is necessary to house the paper cutting assembly, the user slides the paper cutter to the end of the mounting base away from the receiving groove, and then flips the mounting base so that the paper cutter is directly opposite the receiving groove. At this time, the receiving groove can just hold the paper cutter, which is beneficial for blind operation, simple to use, and effortless to assemble and disassemble.

[0011] As an improvement, the paper cutter includes a housing and a switch movably mounted on the housing. A blade assembly, comprising multiple blades, is installed inside the housing. The blade assembly is linked to the switch; force applied to the switch drives the blade assembly to switch between different blades for cutting paper. In this technical solution, a blade assembly composed of multiple blades is installed inside the paper cutter's housing. The user applies force to the switch to drive the blade assembly to switch between different blades, allowing the user to change blades according to different cutting needs, thus improving practicality.

[0012] As an improvement, the switch is rotatably mounted on the housing, and the blade assembly is mounted in a disc-like shape inside the housing. The switch drives the blade assembly to rotate, switching between different blades for cutting paper. In this technical solution, the switch is a rotary switch, and the multiple blades in the blade assembly are arranged in a disc-like shape. The user can rotate the blade assembly inside the housing by turning the switch, thereby enabling different blades to cut paper. Furthermore, the user can quickly switch to the desired blade by rotating the switch without replacing or reinstalling the blade, which greatly reduces the time spent changing blades and improves work efficiency. The rotary drive method is not only labor-saving but also space-saving.

[0013] As an improvement, the blade assembly includes straight blades, wavy blades, and dotted blades. In this technical solution, the blade assembly is composed of straight blades, wavy blades, and dotted blades. The straight blades are suitable for conventional straight cutting, the wavy blades are suitable for decorative or special effect cutting, and the dotted blades are suitable for continuous cutting that requires tearing. This design allows the paper cutter to meet a variety of cutting tasks, improving the applicability and flexibility of the tool. Attached Figure Description

[0024] like Figures 1 to 5 As shown, this application discloses a laminating machine, including a base 1 and a paper cutting assembly 2. The paper cutting assembly 2 is detachably installed on the base 1. The base 1 is provided with a receiving cavity 11 adapted to the paper cutting assembly 2. After the paper cutting assembly 2 is removed from the base 1, it can be stored in the receiving cavity 11 by flipping it over. The paper cutting assembly 2 includes a paper cutter 21 and a mounting base 22. Considering that the paper cutter 21 will cause the top of the base 1 to protrude when the paper cutting assembly 2 is installed on the base 1, the space required for storage is large. By setting the paper cutting assembly 2 to be detachably connected to the base 1, and the receiving cavity 11 on the base 1 that can store the paper cutting assembly 2, the paper cutting assembly 2 can be removed from the base 1 after use and then flipped over to be stored in the receiving cavity 11. This makes full use of the internal space of the base 1 and helps to reduce the size of the whole machine.

[0025] The paper cutter 21 is slidably mounted on the mounting base 22. The length of the receiving cavity 11 is adapted to the sliding path of the paper cutter 21 to accommodate the paper cutter 21 in any position. By sliding the paper cutter 21 on the mounting base 22, the paper cutter 21 can cut documents at different positions to meet more usage needs. Therefore, the position of the paper cutter 21 on the mounting base 22 is not fixed. By adapting the length of the receiving cavity 11 to the sliding path of the paper cutter 21, the range of movement of the paper cutter 21 during use is fully considered. This ensures that no matter where the paper cutter 21 slides on the mounting base 22, it can be completely stored in the receiving cavity 11 by flipping. Users do not need to confirm the storage position of the paper cutter 21 in advance, which improves the convenience and comfort of use. Moreover, the disassembly and assembly of the paper cutting component 2 is easier and simpler.

[0026] More specifically, such as Figures 1 to 3As shown, the mounting base 22 is movably connected to the receiving cavity 11. When the mounting base 22 is subjected to force, one end of it can detach from the receiving cavity 11 and slide and flip relative to the receiving cavity 11. By flipping, the mounting base 22 allows the paper cutter 21 to be stored inside the receiving cavity 11 and covers the receiving cavity 11. The movable connection between the mounting base 22 and the receiving cavity 11 allows the mounting base 22 to partially detach from the receiving cavity 11 when subjected to force to obtain movement space. When the user applies force to the mounting base 22, one end of the mounting base 22 can detach from the receiving cavity 11, and the movement of the mounting base 22 is not restricted. This ensures that the opening of the receiving cavity 11 can be completely hidden when the mounting base 22 is installed on the receiving cavity 11, and also allows the mounting base 22 to slide and flip relative to the receiving cavity 11. This enables the mounting base 22 to be effectively flipped and stored in space-constrained conditions, which helps to reduce the overall storage size of the machine, makes the space distribution more reasonable, and makes the disassembly and assembly of the paper cutting assembly 2 easier and simpler.

[0027] More specifically, such as Figures 1 to 3 As shown, the inner wall of the accommodating cavity 11 is provided with a first slide rail 12, and the side wall of the mounting base 22 is provided with a first rotating shaft 221 adapted to the first slide rail 12. The first rotating shaft 221 is connected to the first slide rail 12 so that the mounting base 22 can slide and flip relative to the accommodating cavity 11. By providing the first slide rail 12 in the accommodating cavity 11 and the first rotating shaft 221 on the mounting base 22, and by connecting the first rotating shaft 221 to the first slide rail 12, the mounting base 22 can slide relative to the accommodating cavity 11, and the mounting base 22 can flip relative to the accommodating cavity 11 through the first rotating shaft 221. The structural design is ingenious and reliable, which is conducive to improving space utilization and is convenient and labor-saving to use.

[0028] More specifically, such as Figures 1 to 3 As shown, the first rotating shaft 221 is disposed on the side wall of one end of the mounting base 22. The first rotating shaft 221 cooperates with the first slide rail 12 to limit one end of the mounting base 22 to be located in the receiving cavity 11. By disposing of the first rotating shaft 221 on the end of the mounting base 22, one end of the mounting base 22 is always connected to the receiving cavity 11, and this end of the mounting base 22 can slide and flip through the first rotating shaft 221. The overall stability is better and the use is more reliable. The user only needs to apply force to the other end of the mounting base 22 to make it detach from the receiving cavity 11, so that the mounting base 22 has room to move, slide and flip. The structural design is more ingenious and reliable.

[0029] More specifically, such as Figure 2As shown, two first slide rails 12 are symmetrically arranged on the inner wall of the accommodating cavity 11, and two first rotating shafts 221 are symmetrically arranged on the side wall of the mounting base 22. Two first slide rails 12 are symmetrically arranged on the inner wall of the accommodating cavity 11, and the two first slide rails 12 are respectively located on both sides of the mounting base 22. The first rotating shafts 221 corresponding to the first slide rails 12 are respectively arranged on the side walls of the mounting base 22. The two first rotating shafts 221 correspond one-to-one with the two first slide rails 12, providing two-point support for the mounting base 22. This support method improves the stability of the structure, reduces the tilting or imbalance that may be caused by single-point support, helps to maintain the balance of the mounting base 22 during sliding and flipping, and improves storage efficiency.

[0030] More specifically, such as Figures 1 to 3 As shown, the mounting base 22 is provided with a base plate 222, which is a planar structure. When the mounting base 22 flips to close the receiving cavity 11, the base plate 222 is flush with the surface of the machine base 1. The planar structure of the base plate 222 of the mounting base 22 ensures that when the mounting base 22 flips to close the receiving cavity 11, the base plate 222 can form a flat surface with the surface of the machine base 1, so that the paper cutting assembly 2 can be better stored in the base, which not only improves the visual appearance, but also helps to reduce the storage size of the whole machine.

[0031] More specifically, such as Figure 2 As shown, one end of the receiving cavity 11 is provided with a receiving groove 111 adapted to the paper cutter 21. When the paper cutter 21 slides away from the receiving groove 111 to the end of the mounting base 22, the mounting base 22 slides and flips relative to the receiving cavity 11 to house the paper cutter 21 in the receiving groove 111. The paper cutter 21 is slidably mounted on the mounting base 22, and the paper cutter 21 protrudes relative to the mounting base 22. By providing a receiving groove 111 in the receiving cavity 11 specifically for housing the paper cutter 21, the paper cutter 21 is prevented from sliding back and forth in the receiving cavity 11. The 11 pairs of paper cutters 21 are positioned to limit and store, improving storage stability and preventing damage from collisions. The receiving groove 111 is located at the end of the receiving cavity 11, and the receiving groove 111 is opposite to the end of the mounting base 22 after it is flipped. When it is necessary to store the paper cutting assembly 2, the user slides the paper cutter 21 to the end of the mounting base 22 away from the receiving groove 111, and then flips the mounting base 22 so that the paper cutter 21 is directly opposite the receiving groove 111. At this time, the receiving groove 111 can just hold the paper cutter 21, which is conducive to blind operation, simple to use, and effortless to disassemble and assemble.

[0032] More specifically, such as Figure 4 and Figure 5As shown, the paper cutter 21 includes a housing 211 and a switch 212 movably mounted on the housing 211. A blade assembly 213 is installed inside the housing 211. The blade assembly 213 includes multiple blades. The blade assembly 213 is linked to the switch 212. When the switch 212 is subjected to force, it drives the blade assembly 213 to move to switch between different blades for cutting paper. The blade assembly 213 is set inside the housing 211 of the paper cutter 21. The blade assembly 213 consists of multiple blades. The user applies force to the switch 212 to drive the blade assembly 213 to move and switch between different blades. The user can change the blades according to different cutting needs, which improves practicality.

[0033] More specifically, such as Figure 4 and Figure 5 As shown, switch 212 is rotatably mounted on housing 211, and blade assembly 213 is mounted in a disc shape inside housing 211. Switch 212 drives blade assembly 213 to rotate to switch between different blades for cutting paper. Switch 212 is a rotary switch 212, and multiple blades in blade assembly 213 are arranged in a disc shape. Users can rotate switch 212 to drive blade assembly 213 to rotate inside housing 211, thereby enabling different blades to cut paper. Furthermore, rotating switch 212 allows for quick switching to the desired blade without the need to replace or reinstall the blade, which greatly reduces the time spent changing blades and improves work efficiency. The rotary drive method is not only labor-saving but also space-saving.

[0034] More specifically, such as Figure 4 and Figure 5 As shown, the blade assembly 213 includes straight blades, wavy blades, and dotted blades. The straight blades are suitable for regular straight cutting, the wavy blades are suitable for decorative or special effect cutting, and the dotted blades are suitable for continuous cutting that requires tearing. This design allows the paper cutter 21 to meet various cutting tasks, improving the tool's applicability and flexibility. Straight lines, wavy lines, and dotted lines are marked on the surface of the switch 212. The straight lines correspond to the straight blades, the wavy lines to the wavy blades, and the dotted lines to the dotted blades, facilitating user selection of the desired blade.

[0035] This application is not limited to the above-described preferred embodiments. Anyone can derive other products in various forms under the guidance of this application. However, regardless of any changes made to their shape or structure, any technical solution that is the same as or similar to that of this application falls within the protection scope of this application.
