Description

Technical Field

[0001] The invention relates to the technical field of laminating equipment, and in particular to a manual cold laminating machine for covering the surface of a sheet with a cold laminating film. Background Art

[0002] In scenarios such as advertising graphic production and photographic work output, manual cold laminators, as key equipment for laminating the surfaces of posters, photos and other sheet materials, often require high-frequency, batch operations. The core of the laminating process lies in the uniform and stable pressing of the sheet and the cold laminating film by the pressure roller. However, the operating procedures and structural design of traditional manual cold laminators have significant pain points: on the one hand, every time the sheet is changed or the thickness is adjusted, the operator must operate in two steps - first open the top cover, and then manually adjust the distance between the movable pressure roller and the fixed pressure roller. This separate operating mode is cumbersome and time-consuming, especially in batch operations, which greatly reduces efficiency; on the other hand, manual adjustment makes it difficult to accurately ensure the synchronization of pressure on both sides, which can easily lead to uneven pressing, bubbles or wrinkles, and affect the quality of lamination.

[0003] Existing equipment also faces challenges in structural integration and stability: The inconvenience of replacing the material rolls hinders film change efficiency; the top cover locking mechanism is rudimentary, posing the risk of accidental opening or loose closure; and the independent trimming function often requires additional tools or steps. These issues not only directly impact operational efficiency and yield, but the frequent adjustments and potential equipment instability also increase operator workload, creating a bottleneck in improving the manual lamination experience and efficiency.

[0004] To this end, the present invention provides a manual cold laminator with an innovative structure, which strives to achieve the integrated operation of "loosening the roller when opening the cover and pressing when closing the cover" through unique linkage transmission and integrated design, and improves the overall stability and functionality. Summary of the Invention

[0013] A control handle is used to control the manual cold laminating machine to cover the surface of the sheet to be laminated with a layer of cold laminating film.

DETAILED DESCRIPTION

[0033] Reference Figures 1 to 14 , a manual cold laminator, comprising:

[0034] Housing body 100;

[0035] An upper housing assembly 200 rotatably connected to the housing body 100 ;

[0036] A material roller assembly 300, the material roller assembly 300 is detachably connected to the housing body 100;

[0037] A pressure roller assembly 400, the pressure roller assembly 400 being connected to the frame body and comprising a fixed pressure roller 410 and a movable pressure roller 420, wherein the movable pressure roller 420 can selectively move closer to or farther from the fixed pressure roller 410;

[0038] The transmission assembly 500 is configured such that when the upper housing assembly 200 is opened, the rotation of the upper housing assembly 200 drives the movable pressure roller 420 via the transmission assembly 500, so that the movable pressure roller 420 moves away from the fixed pressure roller 410; and when the upper housing assembly 200 is closed, the rotation of the upper housing assembly 200 drives the movable pressure roller 420 via the transmission assembly 500, so that the movable pressure roller 420 moves closer to the fixed pressure roller 410.

[0039] The control handle 700 is used to control the manual cold laminating machine to cover the surface of the sheet to be laminated with a layer of cold laminating film.

[0040] Through the arrangement of the above structure, when in use, the casing body 100 serves as a basic frame, providing installation support for all components such as the upper casing assembly 200 and the material roller assembly 300, thereby ensuring the stability of the overall structure of the equipment; the upper casing assembly 200 realizes opening and closing actions through a rotatable connection, and its rotational motion is not only a direct action input for the operation, but also converted into control of the pressure roller assembly 400 through the transmission assembly 500 - when opened, it drives the movable pressure roller 420 away from the fixed pressure roller 410, which is convenient for placing the sheet to be coated; when closed, it drives the movable pressure roller 420 close to the fixed pressure roller 410 to form the pressure environment required for lamination; the detachable design of the material roller assembly 300 makes it easy to install and replace the cold laminating film roll, providing a source of material for lamination; the control handle 700 serves as an operating terminal, which directly controls the operation of the equipment through the gear assembly. Specifically, it controls the pressure roller assembly 400 through the gear assembly, and drives the cold laminating film to cover the surface of the sheet to be coated, thereby completing the entire cold laminating process. Each structure forms an organic whole through mechanical linkage, which realizes the orderly progress of cold mounting operations from support, operation input, material supply, pressure control to final execution.

[0041] In this embodiment, the transmission assembly 500 includes a transmission plate 510, the transmission plate 510 is provided with an upper cover connecting groove 511 and a pressure roller mounting groove 512, the upper housing assembly 200 includes a transmission connection part 210, the movable pressure roller 420 is provided with an execution connection part 421, the transmission connection part 210 is connected to the upper cover connecting groove 511, and the execution connection part 421 is connected to the pressure roller mounting groove 512; when the upper housing assembly 200 is opened, the rotational movement of the upper housing assembly 200 is transmitted through the transmission connection part 210 and the upper cover The cooperation of the connecting groove 511 drives the transmission plate 510, and then drives the movable pressure roller 420 away from the fixed pressure roller 410 through the cooperation of the pressure roller mounting groove 512 and the execution connection part 421; when the upper housing assembly 200 is closed, the rotational movement of the upper housing assembly 200 drives the transmission plate 510 through the cooperation of the transmission connection part 210 and the upper cover connecting groove 511, and then drives the movable pressure roller 420 close to the fixed pressure roller 410 through the cooperation of the pressure roller mounting groove 512 and the execution connection part 421. With the above-described structural arrangement, the transmission assembly 500 is the key to achieving the linkage between the upper housing assembly 200 and the movable pressure roller 420 during operation: the transmission plate 510, serving as the core transmission component, cooperates with the transmission connection portion 210 of the upper housing assembly 200 through the upper cover connection slot 511 thereon, stably receiving and transmitting the rotational motion of the upper housing assembly 200. Simultaneously, the movement of the transmission plate 510 is converted into displacement of the movable pressure roller 420 by the cooperation between the pressure roller mounting slot 512 and the actuating connection portion 421 of the movable pressure roller 420. When the upper housing assembly 200 is opened, the transmission connection portion 210 drives the transmission plate 510 through the upper cover connection slot 511. The cooperation between the pressure roller mounting slot 512 and the actuating connection portion 421 precisely drives the movable pressure roller 420 away from the fixed pressure roller 410. When the upper housing assembly 200 is closed, the same transmission path is used to drive the movable pressure roller 420 toward the fixed pressure roller 410. This structural design achieves efficient transmission and conversion of motion through direct cooperation of the mechanical structure, ensures the synchronization and accuracy of the operation of the upper housing assembly 200 and the movement of the movable pressure roller 420, and provides a reliable mechanical basis for the opening and closing control of the pressure roller during cold lamination operations.

[0042] In this embodiment, the transmission assembly 500 also includes an elastic element 520, which is provided with a transmission abutment portion 521 and an execution abutment portion 522. The transmission plate 510 is also provided with a first abutment support portion 513. The movable pressure roller 420 is also provided with a pre-tightening abutment portion 422. The transmission abutment portion 521 abuts against the first abutment support portion 513, and the execution abutment portion 522 abuts against the pre-tightening abutment portion 422. The pre-tightening abutment portion 422 provides a pre-tightening force for the movable pressure roller 420, and the pre-tightening force ranges from 3 to 25N. With the above-mentioned configuration, the structural design of the elastic element 520 in the transmission assembly 500 further optimizes the working state of the movable pressure roller 420 during use: the elastic element 520 abuts against the first abutting support portion 513 of the transmission plate 510 via the transmission abutting portion 521, and cooperates with the pre-tightening abutting portion 422 of the movable pressure roller 420 via the execution abutting portion 522 to provide a pre-tightening force in the range of 3-25N for the movable pressure roller 420. This pre-tightening force ensures that when the movable pressure roller 420 is close to the fixed pressure roller 410, it can still maintain a stable laminating pressure even if there are slight assembly errors or transmission gaps, thus avoiding problems such as laminating bubbles and loose laminating caused by insufficient pressure. At the same time, the reasonable range of 3-25N ensures effective lamination between the cold laminating film and the sheet to be laminated without damaging the sheet or the cold laminating film due to excessive pressure. The mechanical cooperation between the elastic element 520, the transmission plate 510 and the movable pressure roller 420 converts the elastic force into a controllable preload force, which complements the linkage effect of the transmission plate 510, so that the movement of the movable pressure roller 420 is not only synchronized and precise, but also maintains a stable working pressure, which significantly improves the quality stability of the cold laminating operation.

[0043] In this embodiment, the first abutment support portion 513 is provided with an abutment protrusion 5131 and a limiting protrusion 5132 extending from the end of the abutment protrusion 5131 , the transmission abutment portion 521 abuts against the abutment protrusion 5131 , and the limiting protrusion 5132 is used to limit the lateral displacement of the transmission abutment portion 521 . Through the setting of the above-mentioned structure, when in use, the abutment protrusion 5131 and the limiting protrusion 5132 structure of the first abutment support part 513 provide key guarantees for the stable cooperation between the elastic element 520 and the transmission plate 510: the abutment protrusion 5131 serves as a direct force point, providing a clear and stable abutment basis for the transmission abutment part 521, avoiding preload force loss or fluctuation caused by blurred contact area or force point offset; and the limiting protrusion 5132 extends from the end of the abutment protrusion 5131, which can effectively limit the lateral displacement of the transmission abutment part 521, preventing the elastic element 520 from being laterally offset during force deformation or equipment operation, and ensuring that the transmission abutment part 521 always maintains a precise cooperation relationship with the abutment protrusion 5131. The combination of the two not only enhances the force transmission efficiency between the elastic element 520 and the transmission plate 510, but also maintains the stability of the fit through structural limitation, providing reliable support for the continuous stability of the preload force of the movable pressure roller 420, and further improving the working reliability of the entire transmission system.

[0044] In this embodiment, a trimming assembly 600 is also included, and the trimming assembly 600 includes a mounting element 610, a guide rail element 620 and a cutting element 630. The movable pressure roller 420 is provided with an accessory connection portion 423. The cutting element 630 is slidably connected to the guide rail element 620. The guide rail element 620 is fixedly connected to the mounting element 610. The mounting element 610 is connected to the accessory connection portion 423. With the above-mentioned structure, when in use, the trimming assembly 600 provides a convenient trimming function for cold laminating operations, forming an efficient synergy with the main body of the machine: the mounting element 610 is connected to the attachment connection parts 423 provided at both ends of the movable pressing roller 420, stably mounting the entire trimming assembly 600 on the movable pressing roller 420, so that the trimming operation can be synchronized with the movement of the movable pressing roller 420, ensuring that the cutting position matches the laminating progress; the guide element 620 is fixed to the mounting element 610, providing a stable sliding track for the cutting element 630, and the cutting element 630 can slide along the guide element 620, so that the cutting position can be flexibly adjusted according to the size of the sheet to be laminated, meeting the trimming requirements of different specifications of materials. This structure integrates the trimming function into the movable pressing roller 420, eliminating the step of separate cutting after lamination, simplifying the operation process, and ensuring the accuracy of trimming through sliding adjustment, avoiding the deviation that may occur in manual secondary cutting, further improving the overall operating efficiency and product quality of the manual cold laminator.

[0045] In this embodiment, the mounting element 610 is provided with a guide rail mounting hole 611 and a mounting abutment portion 612, the guide rail element 620 is provided with a guide rail mounting shaft 621, and the transmission plate 510 is also provided with a second abutment support portion 514. The guide rail mounting shaft 621 cooperates with the guide rail mounting hole 611 to fix the guide rail element 620 to the mounting element 610, and the mounting abutment portion 612 abuts against the second abutment support portion 514. By setting the above structure, when in use, the cooperation structure of the guide rail mounting hole 611 of the mounting element 610, the mounting abutment portion 612, the guide rail mounting shaft 621 of the guide rail element 620, and the second abutment support portion 514 of the transmission plate 510 further enhances the stability and coordination of the trimming assembly 600: the precise cooperation between the guide rail mounting hole 611 and the guide rail mounting shaft 621 provides a reliable positioning and fastening effect for the fixed connection between the guide rail element 620 and the mounting element 610, ensuring that the guide rail element 620 is fixed to the cutting element 600. During the sliding process, the component 630 will not loosen or deflect, laying the foundation for the stable sliding of the cutting element 630. The mounting abutment portion 612 abuts the second abutment support portion 514 of the transmission plate 510, providing an additional support point for the mounting element 610 through the transmission plate 510. This disperses the force at the connection between the mounting element 610 and the movable pressure roller 420, preventing deformation of the mounting structure caused by the force generated by the trimming operation. At the same time, it creates a closer linkage between the trimming assembly 600 and the transmission system, reducing vibration during the cutting process and improving cutting accuracy. This structural design optimizes the working state of the trimming assembly 600 from the perspectives of connection, fixation, and force support, further ensuring the accuracy and reliability of the trimming operation.

[0046] In this embodiment, the mounting abutment portion 612 is provided with an abutment protrusion 6121 and a limiting protrusion 6122 extending from the end of the abutment protrusion 6121 , the transmission abutment portion 521 abuts against the abutment protrusion 6121 , and the limiting protrusion 6122 is used to limit the lateral displacement of the second abutment support portion 514 . With the above-mentioned structural arrangement, when in use, the abutting protrusion 6121 and the limiting protrusion 6122 structure of the mounting abutting portion 612 further optimize the matching stability between the mounting element 610 and the transmission plate 510: the abutting protrusion 6121 provides a precise contact point for the mounting abutting portion 612 and the second abutting support portion 514 of the transmission plate 510, ensuring that the abutting force between the two is concentrated and stable, avoiding uneven force caused by excessive contact area or irregular shape, thereby ensuring that the mounting element 610 obtains reliable support force; the limiting protrusion 6122 extends from the end of the abutting protrusion 6121, and can limit the lateral displacement of the second abutting support portion 514, preventing the transmission plate 510 and the mounting element 610 from lateral relative movement during equipment operation or trimming operation, ensuring that the two always maintain a stable matching relationship, further improving the reliability of the linkage between the trimming assembly 600 and the transmission system, and reducing cutting errors caused by loose or offset matching.

[0047] In this embodiment, the transmission plate 510 is further provided with a third abutting support portion 515, and the elastic element 520 is further provided with an intermediate abutting portion 523, which abuts against the third abutting support portion 515. Through the above-mentioned structure, when in use, the third abutting support portion 515 of the transmission plate 510 cooperates with the intermediate abutting portion 523 of the elastic element 520, further improving the working stability of the elastic element 520; the intermediate abutting portion 523 abuts against the third abutting support portion 515, adding a force support point for the elastic element 520, so that the elastic element 520 is subjected to more balanced force during deformation and force transmission, avoiding tilting or offset that may occur due to single-point support; at the same time, this multi-point support structure can effectively disperse the reaction force on the elastic element 520, reduce fatigue loss caused by long-term force, and extend its service life, thereby continuously and stably providing preload force to the movable pressing roller 420, ensuring pressure stability during cold laminating operation.

[0048] In this embodiment, the third abutting support portion 515 is provided with an abutting boss 5151 and a limiting boss 5152 extending from the end of the abutting boss 5151. The intermediate abutting portion 523 abuts against the abutting boss 5151, and the limiting boss 5152 is used to limit the lateral displacement of the intermediate abutting portion 523. Through the above-mentioned structural arrangement, when in use, the abutting boss 5151 and the limiting boss 5152 of the third abutting support portion 515 further enhance the cooperation effect with the intermediate abutting portion 523 of the elastic element 520: the abutting boss 5151 provides a precise abutting position for the intermediate abutting portion 523, ensuring concentrated and stable force; and the limiting boss 5152 limits the lateral displacement of the intermediate abutting portion 523, preventing the elastic element 520 from deflecting during force transmission or deformation. The combination of the two makes the multi-point support of the elastic element more reliable and the force transmission more precise, further ensuring the stable output of the preload force and enhancing the pressure stability of the cold lamination operation.

[0049] In this embodiment, the upper cover connection groove 511 includes a latching groove portion 5111 and a curved groove portion 5112. The latching groove portion 5111 is connected to the curved groove portion 5112. When the upper housing assembly 200 is opened, the transmission connection portion 210 is located in the latching groove portion 5111; when the upper housing assembly 200 is closed, the transmission connection portion 210 is located in the curved groove portion 5112. With the above-described structure, when the upper housing assembly 200 is opened, the transmission connection portion 210 is located in the latching groove portion 5111, thereby stably limiting the position of the transmission plate 510 and preventing the movable pressure roller 420 from accidentally moving. When the upper housing assembly 200 is closed, the transmission connection portion 210 enters the curved groove portion 5112, guiding the transmission plate 510 to move smoothly along a curved trajectory, thereby driving the movable pressure roller 420 to precisely approach the fixed pressure roller 410. This design not only ensures the stability of the equipment when opening and closing, but also ensures the smoothness of the transmission process, thereby improving operational reliability.

[0050] In this embodiment, the housing body 100 includes a first sidewall housing 110, a second sidewall housing 120, and a base housing 130. The lower end of the first sidewall housing 110 is fixedly connected to one end of the base housing 130, and the lower end of the second sidewall housing 120 is fixedly connected to the other end of the base housing 130. Through the above-described configuration, when in use, the structural design of the first sidewall housing 110, the second sidewall housing 120, and the base housing 130 of the housing body 100 provides a stable frame foundation for the device: the lower ends of the first sidewall housing 110 and the second sidewall housing 120 are respectively fixedly connected to the two ends of the base housing 130, forming a symmetrical two-sided support structure that can evenly bear the weight of components such as the upper housing assembly 200 and the pressure roller assembly 400; the base housing 130 serves as a bottom support, enhancing the overall stability of the device and preventing shaking during operation. This structure not only provides a reliable mounting platform for each component, but also ensures the structural stability of the device during operation.

[0051] In this embodiment, the casing body 100 further includes a reinforcing element 140, one end of which is fixedly connected to the upper end of the first side wall shell 110, and the other end is fixedly connected to the upper end of the second side wall shell 120. The reinforcing element 140 is used to reinforce the casing body 100. Through the above-mentioned structural setting, when in use, the reinforcing element 140 of the casing body 100 further strengthens the stability of the overall structure: one end of the reinforcing element 140 is fixed to the upper end of the first side wall shell 110, and the other end is fixed to the upper end of the second side wall shell 120, forming a connection structure that echoes the base shell 130, connecting the two side wall shells more closely together, effectively resisting the lateral force and deformation generated during component installation and operation, and preventing the upper end of the side wall shell from expanding or shaking. Therefore, the bearing capacity and structural stability of the casing body 100 are significantly improved, providing a more reliable framework guarantee for the long-term stable operation of the equipment.
