Description

Technical Field

[0001] The invention relates to a PE film cutting machine for packaging large-plate photovoltaic glass. Background Art

[0002] The PE packaging film used in the glass industry is large, with specifications as large as 3.6 meters by 1.8 meters. Conventional film cutting machines are unable to achieve this. Currently, the glass industry generally uses manual cutting, which is inefficient. Automatic film cutting machines, such as the one disclosed in patent publication number CN208841481U, include a cutter frame, a cutter cylinder, a cutter, a cutter holder, two guide racks, two guide gears, and a guide shaft. The cutter frame is fixedly connected to the frame, the cylinder body of the cutter cylinder is fixedly mounted on the top of the cutter frame, the piston rod end of the cutter cylinder passes downward through the cutter frame and connects to the upper end of the cutter, and the lower end of the cutter extends to the cutter holder, which is fixed to the frame. The two guide racks are respectively mounted on the side walls of the cutter, and the two guide gears are fixedly sleeved on the guide shaft and mesh with the two guide racks. The guide shaft is rotatably mounted on the cutter frame. This type of film cutting machine uses a cylinder to press down the cutter to cut the film. The cut packaging film needs to be taken out manually. If it is used to cut large-sized packaging film, the cutter length has requirements and the cylinder also needs to be adjusted and replenished. In addition, multiple people are required to operate to take out large sheets of packaging film. Therefore, this type of film cutting machine cannot meet the packaging requirements of large-sized packaging films in the glass industry. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a large-plate photovoltaic glass packaging PE film cutting machine that meets the cutting requirements of large-size packaging films.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A large-plate photovoltaic glass packaging PE film cutting machine, comprising:

[0006] A loading device comprising a packaging film roller and a first film guide roller, wherein the packaging film extends from the packaging film roller through the first film guide roller;

[0007] The film cutting device includes a film supporting platform and a film pressing component and a film cutting component installed on the film supporting platform, wherein the film pressing component includes a film pressing block and a first pressing drive mechanism, and the first pressing drive mechanism is driven and connected to the film pressing block; the film cutting component includes a film cutting blade, a second pressing drive mechanism and a first traveling drive mechanism, wherein the film cutting blade and the second pressing drive mechanism are respectively installed on the first traveling drive mechanism, and the second pressing drive mechanism is driven and connected to the film cutting blade, and the packaging film passes through the film supporting platform;

[0008] a film-pulling device comprising an upper clamping component, a lower clamping component, a third downward-pressing drive mechanism, and a second travel drive mechanism, wherein the upper clamping component, the lower clamping component, and the third downward-pressing drive mechanism are respectively mounted on the second travel drive mechanism, and the third downward-pressing drive mechanism drives the upper clamping component to press downward relative to the lower clamping component, so that the upper clamping component and the lower clamping component can clamp the packaging film; and

[0009] A film falling structure, which is located below the film pulling device;

[0010] The film supporting platform is provided with an inserting position, and the lower clamping component is provided with an inserting piece that cooperates with the inserting position. The inserting piece of the lower clamping component can be inserted into the inserting position so that the upper clamping component and the lower clamping component clamp the packaging film on the film supporting platform.

[0011] In another preferred embodiment, there are several packaging film rollers, and several first film guide rollers are correspondingly provided. The first film guide rollers are correspondingly located below the packaging film rollers, and the several first film guide rollers are not on the same horizontal plane.

[0012] In another preferred embodiment, a second film guiding roller is provided on the film supporting platform.

[0020] The beneficial effects of the present invention are: a film cutting device and a film pulling device are adopted. Compared with the film cutting machine in the prior art, the film cutting device has no limit on the width of the packaging film, does not require a long blade, and has no requirement for the stability of the blade's up and down movement. The film pulling device automatically pulls the film, and a film falling structure is provided below the film pulling device. The cut packaging film automatically falls off without manual removal.

The three packaging film rollers 110, 120, 130 can be covered with packaging films of different specifications. The packaging film rollers are bearing rollers and are directly mounted on a double bearing mechanism, which is convenient for loading. When the equipment is pulling the film, the friction can be greatly reduced. The first film guide roller is located below the packaging film roller. The three first film guide rollers 140, 150, 160 are not on the same horizontal plane. Figure 2 As shown, the packaging film on the packaging film roller 110 passes through the first film guide roller 140 and then the first film guide roller 160 and then is sent to the film cutting device, the packaging film on the packaging film roller 120 passes through the first film guide roller 150 and the first film guide roller 160 and then is sent to the film cutting device, and the packaging film on the packaging film roller 130 passes directly through the first film guide roller 160 and is sent to the film cutting device.

[0037] The film cutting device 200 and the film pulling device 300 are installed on the frame 400. Figure 3 As shown, the film cutting device 200 includes a film supporting platform 210 and a film pressing component and a film cutting component installed on the film supporting platform 210. A second film guiding roller 211 is provided on the film supporting platform 210. The film pressing component includes a film pressing block 221 and a first downward pressing drive mechanism 222. The first downward pressing drive mechanism 222 drives and connects the film pressing block 221. The first downward pressing drive mechanism is a cylinder (film pressing cylinder). Due to the large specifications of the packaging film, there are two film pressing blocks 221 and two first downward pressing drive mechanisms 222 in this embodiment. The film cutting component includes a film cutting blade 231, a second downward pressing drive mechanism 232 and a first traveling drive mechanism. The film cutting blade 231 and the second downward pressing drive mechanism 232 are installed on the first traveling drive mechanism. The second downward pressing drive mechanism drives 232 to connect the film cutting blade 231. Figure 4 As shown, the film cutting blade 231 is an inverted triangle structure. Both sides of the inverted triangle film cutting blade are cutting edges, so there is no need to reset before cutting, saving half the cutting time. The second downward driving mechanism 232 is a cylinder (blade cylinder), which presses the blade downward to cut the packaging film.

[0038] The first walking drive mechanism includes a stepper motor 233, a ring gear 234, a slider 235 and a guide rail 236. The stepper motor 233 drives the ring gear 234, and the slider 235 is fixedly connected to the ring gear 234. The slider 235 reciprocates on the guide rail 236. The film cutting blade 231 and the second downward pressing drive mechanism 232 are installed on the slider 235.

[0039] like Figure 5 As shown, the film pulling device 300 includes an upper clamping part 310, a lower clamping part 320, a third downward pressing drive mechanism 330 and a second traveling drive mechanism. The upper clamping part 310, the lower clamping part 320 and the third downward pressing drive mechanism 330 are installed on the second traveling drive mechanism. The third downward pressing drive mechanism 330 drives the upper clamping part 310 to be pressed downward relative to the lower clamping part 320. The third downward pressing drive mechanism 330 is a cylinder (film pulling cylinder). The second traveling drive mechanism includes a servo motor 341 and a rack guide rail 342.

[0040] Combine Figure 3 and Figure 5 Before film cutting, the packaging film needs to be pulled to a set position. At this time, the packaging film head is located on the film support platform 210. To facilitate film pulling, an insertion position 212 is provided on the film support platform. The lower clamping component 320 is provided with an insertion piece 321 that cooperates with the insertion position 212. The insertion piece 321 of the lower clamping component 320 can be inserted into the insertion position 212 so that the upper clamping component 310 and the lower clamping component 320 clamp the packaging film on the film support platform 210. In this embodiment, there are multiple insertion positions 212, and multiple corresponding insertion pieces 321 are provided. The film pulling portions of the lower clamping component 320 and the upper clamping component 310 are configured as similar comb-tooth structures, which are staggered with the insertion position 212 of the film support platform 210 to achieve insertion and film pulling.

[0041] like Figure 3 As shown, a hollow space is provided below the film-drawing device 300 to form a film-falling structure, and an inlet and outlet 410 is provided on one side of the frame 400 .

[0042] like Figure 6 As shown, the frame 400 is equipped with a touch screen 420 and an audible and visual alarm 430. This embodiment utilizes a PLC control system, with parameters set and reports generated via the touch screen 420. The servo motor provides precise control, and the transmission structure utilizes a guide rail and rack, significantly enhancing accuracy. When the set amount of packaging film cut is reached, an alarm is activated to indicate the order is complete, and the packaging film is removed from the lower access opening of the frame to allow for the next job.

[0043] The working process of this embodiment is as follows: the packaging film is in the upper position and pulled onto the film supporting platform, the film cutting blade is at the origin, the servo motor controls the lower clamping component of the film pulling device to insert into the plug-in position of the film supporting platform, the film pulling cylinder is pressed down, the upper clamping component and the lower clamping component clamp the packaging film, the servo motor is started, and the film pulling device is driven to pull the packaging film to the set position; then the film pressing cylinder is pressed down, the film pressing block presses the packaging film to prevent the packaging film from moving during cutting, the blade cylinder is pressed down, the stepper motor is started, and the film cutting blade is driven to cut the packaging film. After cutting is completed, the blade cylinder rises to complete the film cutting, the film pulling cylinder rises, and the packaging film falls. A transfer device, such as a cart with pulleys, can be placed under the frame 400. When a certain amount of packaging film is cut, the cart is transferred and pushed out from the import and export 410.
