Description

Technical Field

[0001] This utility model relates to the field of film cutting technology, specifically to an automatic cutting device for photovoltaic module film. Background Technology

[0002] During the film roll output process, the film needs to be cut to fit the product dimensions due to the different shapes and sizes of the products. This reduces waste, lowers production costs, and facilitates the lamination of the film onto different products, thereby reducing the allowance for subsequent processing, effectively shortening processing time, and improving production efficiency.

[0003] For example, Chinese patent application number 201721254147.9, published on June 12, 2018, discloses a rapid cutting mechanism, including a feeding and conveying device, a shearing section, a driving section, a detection device, an anti-winding ion air bar, and a control system. The feeding and conveying device is located at the inlet of the shearing section, the driving section is connected to the shearing section and the control system, and drives the shearing section to perform shearing. The detection device is located at the inlet of the shearing section and is connected to the control system. It is used to detect information about the material to be sheared and to feed the detected information back to the control system so that the control system can control the start and stop of the driving section. The anti-winding ion air bar is located at the inlet and is used to perform ion air de-statication and shaping on the material to be sheared before shearing.

[0004] The aforementioned literature describes using anti-winding ion bar to eliminate problems such as inaccurate cutting, product damage, and roll material damage caused by static electricity, bending, and adhesion of waste materials and protective films during conveying and cutting. However, the waste materials and protective films are not securely fixed before cutting, which can easily lead to uneven cutting of waste materials and protective films during the cutting process, thus affecting their usability. Utility Model Content

[0005] The purpose of this invention is to provide an automatic cutting device for photovoltaic module film, which facilitates the pressing of the film and thus enables stable cutting of the film. It has a simple structure and high practicality.

[0006] To achieve the above objectives, an automatic cutting device for photovoltaic module film includes a roller pressing device, a cutting device, and two support seats. The two ends of the roller pressing device and the cutting device are respectively connected to two relatively parallel support seats. Support rods are provided on the support seats. The roller pressing device includes an upper roller assembly, a lower roller assembly, a first drive assembly, and two or more second drive assemblies. The cutting device includes an upper cutting assembly, a lower cutting assembly, a third drive assembly, and two or more linkage transmission assemblies. The two ends of the lower roller assembly are rotatably connected to the support seats. The output end of the first drive assembly, located on one side of the lower roller assembly, is connected to the lower roller assembly. The output end of the second drive assembly, located on the support rods, is hinged to the upper roller assembly. The two ends of the lower cutting assembly are fixedly connected to the support seats. The third drive assembly, located on one side of the support seats, is drively connected to the linkage transmission assemblies. The two ends of the upper cutting assembly, located above the lower cutting assembly, are respectively connected to the linkage transmission assemblies.

[0007] In the above structure, when the film needs to be cut, the second drive component drives the upper pressure roller assembly to move upward and disengage from the lower pressure roller assembly. Simultaneously, the third drive component drives the linkage transmission assembly to move, thereby causing the upper cutting component to move upward and disengage from the lower cutting component. When the film is conveyed onto the lower pressure roller assembly, the second drive component drives the upper pressure roller assembly to move downward and reset, causing the upper pressure roller assembly to abut against the lower pressure roller assembly, thus pressing the film. At the same time, the first drive component drives the lower pressure roller assembly to rotate, causing the upper pressure roller assembly and the lower pressure roller assembly to rotate relative to each other, thereby driving the film to continue to be conveyed towards the cutting device. This guides the film to be conveyed flatly and stably onto the cutting device. When the film is conveyed onto the lower cutting component, the first drive component stops working. At this time, the upper pressure roller assembly and the lower pressure roller assembly firmly press the film, and the third drive component drives the linkage transmission assembly, which in turn drives the upper cutting component to move downward and abut against the lower cutting component, thereby stably cutting the film.

[0008] Furthermore, the upper pressure roller assembly includes an upper pressure roller, an upper pressure roller shaft, and two upper connecting seats. The upper pressure roller is sleeved on the upper pressure roller shaft, and the two ends of the upper pressure roller shaft are rotatably connected to the two upper connecting seats respectively.

[0009] The above configuration allows the upper pressure roller to rotate along with the lower pressure roller assembly, thereby guiding the conveying of the film.

[0010] Furthermore, the lower pressure roller assembly includes a lower pressure roller, a lower pressure roller shaft, and two lower connecting seats. The lower pressure roller is sleeved on the lower pressure roller shaft, and the two lower connecting seats are respectively fixedly connected to two support seats. The two ends of the lower pressure roller shaft are respectively rotatably connected to the two lower connecting seats.

[0011] With the above settings, the lower pressure roller can rotate between the support seats under the drive of the first drive component.

[0012] Furthermore, the first drive assembly includes a first drive motor and a first mounting base. The first drive motor is mounted on the first mounting base, and the output end of the first drive motor passes through the first mounting base and is fixedly connected to the lower pressure roller shaft.

[0013] With the above settings, the lower pressure roller shaft can be rotated by the first drive motor.

[0014] Furthermore, the second drive assembly includes a second drive cylinder, a second connecting shaft, and a second mounting base. The second mounting base is fixedly connected to the support column, the second drive cylinder is hinged to the second mounting base, the output end of the second drive cylinder is detachably connected to one end of the second connecting shaft, and the other end of the second connecting shaft is hinged to the upper connecting base.

[0015] The above configuration facilitates the lifting and lowering of the upper pressure roller assembly via the second drive cylinder, and also allows for adjustment of the relative positions of the upper and lower pressure rollers during the lifting and lowering process, thereby better pressing the film.

[0016] Furthermore, the upper cutting assembly includes an upper cutting seat and an upper cutting blade, the upper cutting blade being disposed on the upper cutting seat, and through holes being provided at both ends of the upper cutting seat. The lower cutting assembly includes a lower cutting seat and a lower cutting blade, the lower cutting blade being disposed on the lower cutting seat, and the upper cutting blade and the lower cutting blade being disposed opposite each other. The two ends of the upper cutting seat are respectively hinged to the linkage transmission assembly, and the two ends of the lower cutting seat are provided with connecting seats, and the connecting seats are provided with guide posts that match the through holes. The two ends of the first connecting rod disposed above the upper cutting seat are respectively connected to the guide posts that pass through the through holes of the upper cutting seat in a vertical direction.

[0017] With the above setup, the upper cutting seat can be moved vertically through the linkage transmission assembly, thereby cutting the film.

[0018] Furthermore, the third drive assembly includes a third drive motor and a third mounting base. The third mounting base is disposed on one side of the support base, the third drive motor is mounted on the third mounting base, and the output end of the third drive motor passes through the third mounting base and is connected to the linkage transmission assembly for transmission.

[0019] With the above setup, the linkage transmission assembly can be moved via the third drive motor.

[0020] Furthermore, the linkage transmission assembly includes a first link, a second link, a transmission belt, a driving wheel, and a driven wheel. One end of the first link is hinged to the upper cutting seat, and the other end of the first link is hinged to one end of the second link. The other end of the second link is fixedly connected to the second rotating shaft. The hinge point between the first link and the first connection is eccentrically set with the second rotating shaft. The other end of the second rotating shaft is fixedly connected to the driven wheel. The driven wheel is connected to the driving wheel via the transmission belt. The driving wheel is fixedly connected to one end of the first rotating shaft. The other end of the first rotating shaft passes through the support seat and is fixedly connected to the output end of the third drive motor.

[0021] The above configuration enables the third drive motor to drive the drive wheel to rotate, which in turn drives the driven wheel to rotate via the transmission belt. This causes the driven wheel to drive the second link to rotate, which in turn causes the second link to drive the first link to swing. This, in turn, causes the upper cutting seat to move up and down along the guide column via the first link. Attached Figure Description

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

[0025] like Figures 1 to 2As shown, an automatic cutting device for photovoltaic module film includes a roller pressing device, a cutting device, and two support seats s1. The two ends of the roller pressing device and the cutting device are respectively connected to two relatively parallel support seats s1. The roller pressing device is located on one side of the cutting device. A vertical support rod s2 is provided on the support seat s1. The roller pressing device includes an upper pressure roller assembly, a lower pressure roller assembly, a first drive assembly, and two or more second drive assemblies. The two ends of the lower pressure roller assembly are rotatably connected to the support seats s1. The output end of the first drive assembly located on one side of the lower pressure roller assembly is connected to... The lower pressure roller assembly is connected to the upper pressure roller assembly. The output end of the second drive assembly, which is mounted on the support rod s2, is hinged to the upper pressure roller assembly. The upper pressure roller assembly includes an upper pressure roller s3, an upper pressure roller shaft s4, and two upper connecting seats s5. The upper pressure roller s3 is sleeved on the upper pressure roller shaft s4, and both ends of the upper pressure roller shaft s4 are rotatably connected to the two upper connecting seats s5. The lower pressure roller assembly includes a lower pressure roller s6, a lower pressure roller shaft s7, and two lower connecting seats s8. The lower pressure roller s6 is sleeved on the lower pressure roller shaft s7, and the two lower connecting seats s8 are fixedly connected to two support seats s1. Both ends of the lower pressure roller shaft s7 are fixedly connected to the two support seats s1. The lower connecting seat s8 is rotatably connected. The first drive assembly includes a first drive motor s9 and a first mounting seat s10. The first drive motor s9 is mounted on the first mounting seat s10, and the output end of the first drive motor s9 passes through the first mounting seat s10 and is fixedly connected to the lower pressure roller shaft s7. In this embodiment, two second drive assemblies are provided. The second drive assembly includes a second drive cylinder s11, a second connecting shaft s12, and a second mounting seat s13. The second mounting seat s13 is fixedly connected to the support column s2, and the second drive cylinder s11 is hinged to the second mounting seat s13. The output end of the second drive cylinder s11 is detachably connected to one end of the second connecting shaft s12, and the other end of the second connecting shaft s12 is hinged to the upper connecting seat s5. Thus, under the drive of the first drive assembly, the lower pressure roller s6 can be driven to rotate between the support seats s1, thereby driving the upper pressure roller s3 and the lower pressure roller s6 to rotate relative to each other, thereby guiding the conveying of the material film. In addition, the upper pressure roller assembly is driven to rise and fall by the second drive cylinder s11, which also facilitates the adjustment of the relative position of the upper pressure roller s3 and the lower pressure roller s6 during the rising and falling process, thereby better pressing the material film.

[0026] The cutting device includes an upper cutting assembly, a lower cutting assembly, a third drive assembly, and two or more linkage transmission assemblies. The two ends of the lower cutting assembly are fixedly connected to a support base s1. The third drive assembly, located on one side of the support base s1, is drively connected to the linkage transmission assemblies. The upper cutting assembly, located above the lower cutting assembly, has its two ends connected to the linkage transmission assemblies. The upper cutting assembly includes an upper cutting seat s14 and an upper cutting blade s15. The upper cutting blade s15 is mounted on the upper cutting seat s14, and the upper cutting seat s14 has through holes at both ends. The lower cutting assembly includes a lower cutting seat s16 and a lower cutting blade. The cutting blade is set on the lower cutting seat s16, and the upper cutting blade s15 is set opposite to the lower cutting blade (not shown in the figure). The two ends of the upper cutting seat s14 are respectively hinged to the linkage transmission assembly. The two ends of the lower cutting seat s16 are provided with connecting seats s17. The connecting seats s17 are provided with guide posts s18 that match the through holes. The two ends of the first connecting rod s19 set above the upper cutting seat s14 are respectively connected to the guide posts s18 that pass through the through holes of the upper cutting seat s14 in the vertical direction. Thus, the upper cutting seat s14 can be driven to move in the vertical direction through the linkage transmission assembly, thereby cutting the film.

[0027] The third drive assembly includes a third drive motor s20 and a third mounting base s21. The third mounting base s21 is disposed on one side of the support base s1. The third drive motor s20 is mounted on the third mounting base s21. The output end of the third drive motor s20 passes through the third mounting base s21 and is connected to the linkage transmission assembly. In this embodiment, two linkage transmission assemblies are provided. The linkage transmission assembly includes a first connecting rod s22, a second connecting rod s23, a transmission belt s24, a driving pulley s25, and a driven pulley s26. One end of the first connecting rod s22 is hinged to the upper cutting seat s14, and the other end of the first connecting rod s22 is hinged to one end of the second connecting rod s23. The other end of the second connecting rod s23 is fixedly connected to the second rotating shaft s27. A connecting shaft is provided on the second connecting rod s23. The other end of the first connecting rod s22 is hinged to the connecting shaft s231, and the axis of the connecting shaft s231 is perpendicular to the second rotating shaft s27. The axes of shafts S27 are not on the same straight line, thus the connecting shaft S231 and the second rotating shaft S27 are eccentrically set. The two ends of the second rotating shaft S27 pass through the support base S1 and are respectively fixedly connected to the driven wheel S26 set on one side of the support base S1. The driven wheel S26 is connected to the driving wheel S25 through the transmission belt S24. The driving wheel S25 is fixedly connected to one end of the first rotating shaft S28. The other end of the first rotating shaft S28 passes through the support base S1 and is fixedly connected to the output end of the third drive motor S20. In this way, the third drive motor S20 can drive the driving wheel S25 to rotate, and then drive the driven wheel S26 to rotate through the transmission belt S24. This causes the driven wheel S26 to drive the second connecting rod S23 to rotate, and finally causes the second connecting rod S23 to drive the first connecting rod S22 to swing. This causes the upper cutting seat S14 to rise and fall along the guide column S18 through the first connecting rod S22.

[0028] In this embodiment, as Figure 1 As shown, a limiting plate s29 is provided on one side of the lower cutting seat s16, so that after the upper cutting blade s15 cuts the material film, it can abut against the limiting plate s29 to prevent the upper cutting blade s15 from accidentally touching the lower cutting seat s16.

[0029] In this embodiment, as Figure 1 As shown, the first connecting rod s19 is provided with a limiting buckle s30, and the upper cutting seat s14 is provided with a limiting protrusion s31. The limiting protrusion s31 is slidably connected within the limiting buckle s30, thereby limiting the upper cutting seat s14 in the vertical direction.

[0030] The working principle of this invention is as follows: When the film needs to be cut, the second drive assembly drives the upper pressure roller assembly to move upward and disengage from the lower pressure roller assembly. Simultaneously, the third drive assembly drives the linkage transmission assembly to move, thereby causing the upper cutting assembly to move upward and disengage from the lower cutting assembly. When the film is conveyed to the lower pressure roller assembly, the second drive assembly drives the upper pressure roller assembly to move downward and reset, causing the upper pressure roller assembly to abut against the lower pressure roller assembly, thus pressing the film. At the same time, the first drive assembly drives the lower pressure roller assembly to rotate, causing the upper pressure roller assembly and the lower pressure roller assembly to rotate relative to each other, thereby driving the film to continue to be conveyed towards the cutting device. This guides the film to be conveyed flatly and stably to the cutting device. When the film is conveyed to the lower cutting assembly, the first drive assembly stops working. At this time, the upper pressure roller assembly and the lower pressure roller assembly firmly press the film. Then, the third drive assembly drives the linkage transmission assembly, which in turn drives the upper cutting assembly to move downward and abut against the lower cutting assembly, thereby stably cutting the film.
