Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to a lightweight PVB film cutting tool. Background Technology

[0002] Polyvinyl butyral (PVB) film is a polymer material with excellent adhesion, transparency, and impact resistance, widely used in automotive windshields, architectural laminated glass, and photovoltaic modules. In practical applications, it typically needs to be cut to size according to product requirements. In applications with high precision requirements, it is essential to ensure smooth, burr-free cuts while avoiding contamination or stretching deformation of the film surface.

[0003] Currently, the industry mainly relies on two types of technical solutions for PVB film cutting: one is to use large-scale automated cutting equipment, which can achieve high-efficiency and high-precision large-volume PVB film cutting; the other is to use manual cutting tools, specifically including operators using simple tools such as utility knives and scissors for manual cutting.

[0004] However, in recent years, with the rapid growth of niche markets such as personalized customization, factories often encounter processing requirements that necessitate cutting small quantities of PVB film to specific sizes. On the one hand, large-scale automated cutting equipment is typically suitable for mass production and standardized cutting work, and is not well-suited for personalized customization requirements. On the other hand, manual cutting tools sometimes fail to ensure that the cut meets usage requirements. Therefore, there is an urgent need to design a lightweight cutting tool that can overcome the space limitations of traditional large equipment while also overcoming the high errors of manual tools, meeting the demand for rapid and precise cutting of small quantities of PVB film and filling a technological gap in the market. Utility Model Content

[0005] This utility model provides a lightweight PVB film cutting tool. The cutting tool has a simple structure and is relatively lightweight, enabling it to quickly transfer work according to the user's processing needs. At the same time, the cutting tool can also achieve mechanized cutting work to ensure that the cut meets high usage requirements.

[0006] This utility model is achieved through the following technical solution:

[0007] A lightweight PVB film cutting tool includes: a main frame comprising a feeding frame and a cutting frame disposed on top of the feeding frame, for fixing and mounting the remaining components; a feeding section mounted on the feeding frame, including at least a first drive roller for driving the movement of the PVB film; a discharging section mounted on the feeding frame, including at least a second drive roller for driving the movement of the PVB film; wherein a cutting gap is formed between the feeding section and the discharging section; a cutting kit mounted on the cutting frame, including a cutting blade and a driving device for driving the cutting blade to move, wherein the cutting path formed by the movement of the cutting blade passes through the cutting gap; and a control unit electrically connected to the first drive roller, the second drive roller, and the driving device to transmit control signals to each component.

[0008] As a further improvement of this utility model, the feeding section also includes a first guide roller disposed on the top of the first drive roller, and a feeding channel for accommodating the PVB film is formed between the two.

[0009] As a further improvement of this utility model, the first guide roller is electrically connected to the control unit.

[0010] As a further improvement of this utility model, the discharge section also includes a second guide roller disposed on the top of the second drive roller, and a discharge channel for accommodating the PVB film is formed between the two.

[0011] As a further improvement of this utility model, the second guide roller is electrically connected to the control unit.

[0012] As a further improvement of this utility model, the first drive roller and the second drive roller are provided with friction-enhancing structures.

[0013] As a further improvement of this utility model, the driving device includes a pneumatic propulsion device.

[0014] As a further improvement of this utility model, a limiting module is provided at the bottom of the cutting gap, and the limiting module includes a limiting surface for abutting against the cutting blade.

[0015] As a further improvement of this utility model, an observation window is provided on the side wall of the material conveyor.

[0016] As a further improvement of this utility model, a reference mark is provided on the top of the feeding rack, and the position of the reference mark is adapted to the cutting path.

[0017] The beneficial effects of this utility model include:

[0018] (1) The control signal provided in the control unit can adjust the rotation direction, operation and stop, and speed of the first drive roller and the second drive roller. Before the cutting work begins, the control unit can drive the first drive roller and the second drive roller to rotate at the same speed and in the same direction to transfer the position of the PVB film to be cut to the cutting gap. Then, the rotation of the first drive roller and the second drive roller is stopped so that the position of the PVB film is initially fixed. When the cutting work is carried out, the control unit can output a control signal to make the first drive roller and the second drive roller rotate at the same speed and in opposite directions, so that the PVB film placed at the cutting gap is in a taut state, and at the same time, it can ensure that the position of the PVB film does not shift significantly. Then, the control unit can output a control signal to the drive device to make the cutting blade fall to complete the cutting work of the PVB film. Therefore, with this cutting tool, the use of mechanized feeding and discharging sections can help users accurately move the position of the PVB film, so that the required cutting point is accurately placed under the cutting blade, achieving precise cutting; and the PVB film is kept taut during cutting, which can also ensure that the cut is flat and burr-free, reducing the possibility of stretching deformation near the cut.

[0019] (2) In the preferred structure, the feeding section and the discharging section respectively include a first guide roller disposed on the top of the first drive roller and a second guide roller disposed on the top of the second drive roller. The guide roller and the drive roller cooperate to clamp the PVB film, which can enhance the driving effect of the guide roller on the PVB film and especially improve the tensioning effect of the PVB film during the cutting operation.

[0020] (3) In the preferred structure, a limiting module is set at the bottom of the cutting gap. The limiting module includes a limiting surface for contacting the cutting blade. In this structure, the limiting module and the cutting blade cooperate to form a shearing force on the PVB film, which further ensures that the cut is flat and burr-free, and further optimizes the cutting effect.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0025] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0026] This embodiment provides a lightweight PVB film cutting tool that can be moved to any work location, such as a workbench or the ground, to perform cutting operations as needed by the user. It includes a main body, an infeed section 2, an outlet section 3, a cutting kit 5, and a control section 6. Figure 1 As shown, the main frame 1 includes a feeding frame 101 and a cutting frame 102 disposed on top of the feeding frame 101. These two components are used to fix and install the remaining parts. Specifically, the feeding section 2 and the discharging section 3 are mounted on the feeding frame 101, while the cutting kit 5 is mounted on the cutting frame 102. In this embodiment, after all components are installed, as shown... Figure 2 As shown, a cutting gap 4 is formed between the first drive roller 201 in the feeding section 2 and the second drive roller 301 in the discharging section 3; the cutting blade 501 in the cutting kit 5 is mounted on the cutting frame 102 via a driving device 502, which drives the cutting blade 501 to move and perform cutting work, wherein the cutting path of the cutting blade 501 passes through the cutting gap 4, so that the PVB film placed at the cutting gap 4 can be cut by the cutting blade 501; in addition, the control unit 6 is electrically connected to the first drive roller 201, the second drive roller 301 and the driving device 502, wherein the electrical connection The connection can be wired, such as by direct connection with an electric wire, or wireless, such as by setting infrared signal receivers on the first drive roller 201, the second drive roller 301, and the drive device 502, and setting a matching infrared signal output device in the control unit 6. With the electrical connection, the control unit 6 can transmit control signals to each component. The control signals can adjust the rotation direction, operation and stop, and speed of the first drive roller 201 and the second drive roller 301. For example, in this embodiment, the control unit 6 mainly includes a set of handheld control components, which include left and right movement drive buttons, tensioning and fixing buttons, and cutting buttons.

[0027] Under the above structure, the process of using the cutting tool is as follows:

[0028] First, before the cutting work officially begins, the control unit 6 can drive the first drive roller 201 and the second drive roller 301 to rotate at the same speed and in the same direction to transfer the cutting position on the PVB film to the cutting gap 4. For example, the user can press the left and right movement drive button on the handheld control to drive the first drive roller 201 and the second drive roller 301 to rotate clockwise or counterclockwise, thereby moving the cutting position on the PVB film. Subsequently, the user can stop the rotation of the first drive roller 201 and the second drive roller 301 through the control unit 6 to initially fix the position of the PVB film. For example, the user can release the left and right movement drive button. The first drive roller 201 and the second drive roller 301 will stop operating. Then, when the cutting work is carried out, for example, the user can press the tension fixing button to make the control unit 6 output a control signal to drive the first drive roller 201 and the second drive roller 301 to rotate in opposite directions at the same speed, thereby making the PVB film placed at the cutting gap 4 taut, while ensuring that the position of the PVB film will not shift significantly, thus achieving complete fixation of the PVB film. Finally, for example, the user can press the cutting button, and the control unit 6 will output a control signal to the drive device 502 to make the cutting blade 501 fall to complete the cutting of the PVB film.

[0029] In this structure, the mechanized feeding section 2 and discharging section 3, and their cooperation with the control section 6, help the user accurately move the PVB film, ensuring that the required cutting point is accurately placed below the cutting blade 501, achieving precise cutting. Furthermore, during cutting, the first drive roller 201 and the second drive roller 301 keep the PVB film taut, ensuring that the cut edge of the PVB film is smooth and burr-free after cutting, and reducing the possibility of tensile deformation near the cut edge.

[0030] Preferably, such as Figure 2 As shown, the feeding section 2 also includes a first guide roller 202 disposed on top of the first drive roller 201, forming a feeding channel between them to accommodate the passage of the PVB film. Preferably, as Figure 2 As shown, the discharge section 3 also includes a second guide roller 302 disposed on top of the second drive roller 301, forming a discharge channel between the two to accommodate the PVB film. In this structure, the guide roller and the drive roller cooperate to clamp the PVB film, enabling the drive roller to provide a stronger driving force to the PVB film. When both the feeding section 2 and the discharge section 3 are equipped with corresponding guide rollers, during the cutting process, the enhanced driving force provided by both further ensures that the cutting position of the PVB film and its vicinity are in a taut state, i.e., a horizontal state, thereby further reducing the possibility of tensile deformation near the cut after cutting.

[0031] Preferably, such as Figure 1 As shown, the first guide roller 202 is electrically connected to the control unit 6.

[0032] Preferably, such as Figure 1 As shown, the second guide roller 302 is electrically connected to the control unit 6.

[0033] After the guide roller is also electrically connected to the control unit 6, the control signal issued by the control unit 6 can also synchronously control the guide roller, so that the guide roller can rotate actively and cooperate with its respective drive roller, thereby enhancing the driving force of the feed unit 2 and the discharge unit 3 respectively.

[0034] Preferably, the first drive roller 201 and the second drive roller 301 are provided with friction-enhancing structures to increase the friction between the two and the PVB film, so that the two can provide a stronger driving force for the PVB film.

[0035] Preferably, such as Figure 1 As shown, the drive device 502 includes a pneumatic drive device. On the one hand, the pneumatic drive device has a simple composition and does not require complex components such as motors, gearboxes or hydraulic pumps, which greatly reduces the overall weight and volume of the cutting equipment and meets the goal of lightweight tool design. On the other hand, the pneumatic drive device can achieve millisecond-level action response and quickly complete the pressing-return cycle operation, which is suitable for high-frequency, small-batch operations. In addition, it can accurately control the cutting pressure, avoid problems such as rough cuts and delamination caused by uneven force application, and ensure that the cut has good flatness.

[0036] Preferably, such as Figure 2 As shown, a limiting module 7 is disposed below the cutting gap 4, and the limiting module 7 includes a limiting surface 701 for contacting the cutting blade 501. With this structure, when the cutting blade 501 passes through the cutting gap 4 along the cutting path, it can contact the limiting surface 701. When cutting PVB films with relatively large thicknesses, the limiting surface 701 can support the PVB film, preventing large displacement near the cut. Furthermore, when the tip of the cutting blade 501 contacts the limiting surface 701, it creates a shearing effect on the PVB film, facilitating rapid cutting and ensuring a smooth cut.

[0037] Preferably, such as Figure 1 As shown, an observation window 8 is provided on the side wall of the material feeder 101. When the cutting tool is placed at a high position, the observation window 8 on the side wall allows the user to easily observe the internal operation of the cutting tool, such as whether the PVB film has moved into place, and thus the user can promptly adjust the position of the PVB film through the control unit 6.

[0038] Preferably, a reference mark is provided on the top of the feeding rack 101, and the position of the reference mark is adapted to the cutting path. When the cutting tool is placed at a low position, the user can directly look down to observe whether the PVB film has moved into place. At this time, aligning the cutting position of the PVB film with the reference mark can ensure that when the cutting blade 501 moves along the cutting path, the blade tip on it accurately falls to the cutting position, thereby accurately completing the cutting work.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
