Description

Technical Field

[0001] The present application relates to the technical field of spacer paper cutting in the photovoltaic industry, and in particular to a paper bidirectional cutting device. Background Art

[0002] Photovoltaic glass is a key encapsulation material for solar panels. It boasts high strength, high light transmittance, and excellent weather resistance. Tempered glass applied to photovoltaic panels protects them from wind pressure, sandstorms, hail, large diurnal temperature swings, and other harsh environments, further enhancing the solar cells' ability to withstand these conditions. Furthermore, coated photovoltaic glass exhibits even higher light transmittance, enabling solar cells to generate more electricity.

[0003] In the photovoltaic glass production process, the raw materials go through a series of process flows to become glass ribbons, which are then cut and broken into sheet glass plates. The glass plates will be packaged after edge processing. In order to avoid defects such as scratches and breakage caused by direct stacking of glass, spacer paper will be placed in the middle of the glass packaging, that is, one piece of glass and one piece of spacer paper are packaged. This requires cutting the spacer paper to achieve multiple stacking. However, existing ordinary paper cutters are generally single-piece knives that can only cut on one side and wear out quickly. Once the blade is blunt, it is easy to tear the paper from the non-cutting line, and the problem can only be solved by replacement; moreover, it is easy to produce burrs on the edge of the spacer paper, which is inconvenient to use. For example, Chinese Patent 202111057216.8 discloses a safety paper cutter with a one-way blade for pushing paper cutting. Therefore, in order to solve the above problems, it is necessary to provide a cutting device with better cutting quality. Utility Model Content

[0037] Figures 1 to 7 An embodiment of the paper bidirectional cutting device of the present application is schematically shown.

[0038] like Figures 1 to 7As shown, the present application discloses a bidirectional paper cutting device, comprising: a knife seat 1. A knife shaft 2, which is arranged on the knife seat 1. A cutting blade 3, which is provided with two cutting blades, which are cross-arranged on the knife shaft 2 and form a bite point on each side of the knife seat 1 for horizontal cutting of paper. A locking member 4, which is arranged on the knife shaft 2 and can adjust the intersection angle of the two cutting blades 3, thereby changing the cutting edge position of the cutting blade 3 used. A driving mechanism, which can drive the knife seat 1 to move back and forth horizontally.

[0039] Through the above-mentioned structural design, the present application utilizes cross-arranged cutting blades 3 to form two cutting bite points. Driven by the driving mechanism, the horizontal reciprocating movement realizes two-way cutting of paper, thereby improving cutting efficiency. Moreover, the present application realizes double-blade cutting that intersects up and down at each bite point, and the cutting position is accurate and not prone to burrs. At the same time, the present application is also provided with a locking member 4, which can conveniently adjust the crossing angle of the two cutting blades 3, thereby quickly changing the edge position of the bite point to cope with blade blunting, thereby extending the service life of the cutting blade 3.

[0040] In some embodiments of the present application, Figure 2 、 Figure 6 and Figure 7 As shown, the cutting blades 3 are single-chamfered, double-edged blades, with the two cutting blades 3 mounted crosswise and closely against each other, with the chamfers facing outward. A shaft hole 31 is provided in the center of the cutting blades 3, and the blade shaft 2 is inserted into the shaft hole 31. This allows the cutting blades 3 to rotate about the blade shaft 2 to change the tilt angle. This change in tilt angle changes the position of the cross-engagement point, altering the cutting edge area, allowing for rapid resharpening of a blunted area of ​​the cutting blades 3. This eliminates the need for frequent blade replacement, extending the life of the cutting equipment and making maintenance more convenient and quick.

[0041] In some embodiments of the present application, Figure 2 and Figure 5 As shown, two spaced apart tool holder plates 11 are provided on the top of the tool holder 1, and a through hole is also provided on the tool holder plate 11. The tool shaft 2 passes through the through holes of the two tool holder plates 11, and the crossed cutting blades 3 are clamped and installed between the gaps of the tool holder plates 11, thereby fixing the cutting blades 3.

[0042] In some embodiments of the present application, Figures 1 to 5As shown, the locking member 4 is a locking nut, which is threadedly engaged with the blade shaft 2. By rotating the locking nut toward the blade shaft 2, it compresses the blade holder plate 11, thereby fixing the intersecting angle of the two cutting blades 3. After a period of use, the cutting blades 3 may become blunt at the point of engagement. In this case, the locking nut can be loosened, the inclination angle of the cutting blades 3 can be adjusted, and the locking nut can be tightened again to reposition the point of engagement and re-sharpen the cutting blades 3. Because the locking nut is low-cost and easy to adjust and use, it can reduce the production and maintenance costs of the cutting equipment of this application.

[0043] In some embodiments of the present application, both ends of each cutting blade 3 are provided with paper guide rods (not shown), and the paper guide rods extend outward in a trumpet shape to guide and gather the paper that deviates too much from the cutting blade 3, thereby avoiding the situation where the paper and the cutting blade 3 are misaligned. It is understandable that the outer curve of the paper guide rod needs to be smooth and without bumps, and it is connected to the cutting side blade of the cutting blade 3, so as to facilitate the unimpeded transition and guidance of the paper to the bite point of the cutting blade 3 for paper cutting. In a preferred embodiment of the present application, there is no blade edge on the paper guide rod, so extending it out of the periphery of the cutting blade 3 to guide the paper to be gathered will not endanger the safety of the staff or equipment, thereby reducing safety hazards. In some embodiments of the present application, the paper guide rods can be detachably installed at both ends of the cutting blade 3 by punching, plugging or screwing, so that it is convenient to choose whether to install the paper guide rod according to the actual production conditions.

[0044] In some embodiments of the present application, the cutting blade 3 is made of tungsten steel to improve the strength and wear resistance of the cutting blade 3 and extend its service life.

[0045] In some embodiments of the present application, reference is made to Figure 1 As shown, the drive mechanism includes a linear guide 5, a belt 6, a pulley 7, and a drive motor 8. The blade holder 1 is slidably mounted on the linear guide 5 and connected to the belt 6, allowing it to reciprocate along the linear guide 5 under the drive of the belt 6. The belt 6 is mounted on the pulley 7, which is mounted on the output end of the drive motor 8. The drive motor 8 drives the pulley 7 to rotate, thereby driving the belt 6 to reciprocate. It is understood that the pulley 7 includes a driving pulley and a driven pulley. This application utilizes a combination of the linear guide 5 and the belt 6 to drive the blade holder 1. This ensures smooth and linear reciprocation of the blade holder 1 and the cutting blade 3, thereby ensuring accurate paper cutting, improving cutting quality, and avoiding burrs and tearing. Furthermore, the combination of the linear guide 5 and the belt 6 allows the blade holder 1 to have a large reciprocating stroke, which is sufficient for the production of wide photovoltaic glass panels. In other embodiments of this application, when the photovoltaic glass panels are smaller and the cutting stroke requirement is less stringent, a screw structure can also be used to implement the drive mechanism. This will not be discussed in detail here.

[0046] In some embodiments of the present application, the bidirectional paper cutting device further includes a foreign object detection sensor, the detection area of ​​which covers the reciprocating path of the cutting blade 3 and is interlocked with the drive motor 8. Thus, when a worker's hand or other debris is detected extending into the lateral path of the cutting blade 3, the danger can be promptly detected and the movement of the cutting blade 3 can be stopped, thereby avoiding accidents and improving the safety of the device. In a preferred embodiment of the present application, the foreign object detection sensor can be a grating sensor, which provides accurate detection without obstruction or interference.

[0047] In some embodiments of the present application, reference is made to Figure 2 and Figure 5 As shown, the lower portion of the tool holder 1 is provided with a plurality of mounting holes 12, and the tool holder 1 is connected to the linear guide rail 5 through the plurality of mounting holes 12. In the actual installation process, the tool holder 1 can be directly connected to the slider of the linear guide rail 5 through the mounting holes 12 to achieve the connection between the two, and a connecting plate is provided on the outside of the two to further connect the belt 6.

[0048] In some embodiments of the present application, the linear guide rail 5 is a dovetail groove guide rail, which can ensure that the tool holder 1 slides smoothly and stably, and prevent the tool holder 1 from getting stuck and affecting the cutting work.

[0049] Combine Figures 1 to 7 As shown, the working principle of the paper bidirectional cutting device of this application in photovoltaic production is explained:

[0050] During normal production, this paper bidirectional cutting device is pre-parked on one side of the spacer paper. After each glass plate is taken out and placed, the paper roll will put the spacer paper outward to the upper surface of the glass plate, and then take out and put down another glass plate to press the spacer paper. After that, the driving mechanism of the present application starts to drive the knife holder 1 and the cutting blade 3 to move horizontally to perform paper cutting in the first direction. The spacer paper will be cut off when it passes through the bite point edge of the cutting blade 3. When the driving mechanism drives the knife holder 1 to move to the other side of the spacer paper, the spacer paper is completely disconnected, the paper cutting is completed, and the driving mechanism stops moving. After that, the paper roll puts out the spacer paper again to cover the surface of the glass plate, and then takes out and puts down another glass plate to press the spacer paper. After that, the driving mechanism drives the knife holder 1 to move horizontally in the opposite direction to cut the paper in the second direction, and repeats this cycle to achieve bidirectional cutting of paper.

[0051] When the cutting edge of the bite point of the cutting blade 3 is blunt, the locking nut can be loosened to adjust the crossing angle of the cutting blade 3, thereby moving the bite point to a new position of the cutting blade 3 to achieve re-sharpening of the cutting edge to meet the needs of long-term cutting work.

[0052] In summary, the paper bidirectional cutting device includes: a knife seat, a knife shaft, a cutting blade, a locking member and a driving mechanism; the knife shaft is arranged on the knife seat; the cutting blade is provided with two pieces, which are cross-arranged on the knife shaft and form a bite point on each side of the knife seat for horizontally cutting the paper; the locking member is arranged on the knife shaft and can adjust the intersection angle of the two cutting blades; the driving mechanism drives the knife seat to move back and forth horizontally. The present application utilizes cross-arranged cutting blades to form two cutting bite points. Driven by the driving mechanism, the horizontal reciprocating movement realizes bidirectional cutting of paper and improves cutting efficiency. Moreover, the present application realizes double-knife cutting that intersects up and down at each bite point, and the cutting position is accurate and not prone to burrs. At the same time, the present application is also provided with a locking member, which can easily adjust the intersection angle of the two cutting blades, thereby quickly changing the edge position of the bite point to cope with blade blunting and extend the service life of the cutting blade.

[0053] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
