Description

Technical Field

[0001] This utility model relates to the field of glass production technology, and in particular to a glass cutting device. Background Technology

[0002] In the scribing and breaking process of substrate glass or carrier glass, the glass goes through the following steps in sequence: loading, scribing, breaking, unloading and sampling inspection. The semi-finished glass is put into the processing line and precisely scribed and broken to remove the feed part by glass cutting devices such as cross-cutting machines or longitudinal cutting machines, so as to meet the required size of the product.

[0003] In related technologies, when a glass cutting device scribing lines on glass, the glass needs to be supported by an anvil, allowing it to adhere to the anvil. Then, a cutter is used to press down on the glass and scribing lines are drawn. Finally, a breaking mechanism breaks the glass along the scribing lines, thus removing the glass's filler portion. Both scribing and breaking actions generate glass dust, which floats or adheres to the upper and lower surfaces of the glass, affecting product quality. Utility Model Content

[0004] The purpose of this invention is to provide a glass cutting device that blocks and collects glass dust generated during the scribing and breaking process, thereby improving the cleanliness of the upper and lower surfaces of the glass and the quality of the product.

[0005] To achieve this objective, the technical solution adopted by this utility model is as follows:

[0006] Glass cutting apparatus, including:

[0007] An anvil, the top of which is provided with a support platform for supporting the glass;

[0008] A scribing mechanism includes a blade holder and a cutter. The blade holder is disposed above the anvil, and the cutter is slidably disposed on the blade holder along the scribing direction. The cutter is configured to press the glass against the support table and slide along the scribing direction to scribing a line on the upper surface of the glass.

[0009] A dust collection mechanism is used to collect dust from the upper and lower surfaces of the glass.

[0010] Two dust baffles are provided, with one end of each dust baffle along the height direction respectively disposed on the anvil and the knife holder; both dust baffles are located on the side of the cutter away from the feed portion of the glass; the dust baffles extend at least to both ends of the glass along the scribing direction, and the other ends of each dust baffle along the height direction respectively abut against the upper and lower surfaces of the glass.

[0011] Alternatively, the two dust baffles may be positioned opposite each other along the height direction.

[0012] As an optional solution, the dust baffle is a rubber sheet, and the other ends of the two rubber sheets along the height direction are elastically abutted against the upper and lower surfaces of the glass, respectively.

[0013] As an optional solution, the anvil is provided with a first slot, the knife holder is provided with a second slot, one end of the dust baffle along the height direction is engaged in the first slot, and the other end of the dust baffle along the height direction is engaged in the second slot.

[0014] As an optional feature, an antistatic film is affixed to the side of the dust baffle facing the cutter.

[0015] As an optional solution, both the anvil and the knife holder are equipped with an anti-static mechanism, which is located on the side away from the feed section of the glass.

[0016] As an optional solution, the static elimination mechanism is a windless ion bar.

[0020] The beneficial effects of this utility model are as follows:

[0021] The glass cutting device proposed in this invention addresses the issue of dust adhering to both the upper and lower surfaces of the glass during the cutting process, specifically the process of the cutter scoring the upper surface and the subsequent breaking of the feed section. Dust baffles are installed on both the anvil and the blade holder, with the baffles positioned on the side of the cutter furthest from the feed section of the glass. The other ends of the two baffles, along their height, abut against the upper and lower surfaces of the glass, respectively, to prevent dust from spreading over a large area.

[0032] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] This embodiment provides a glass cutting device for scoring and breaking glass edges to achieve the required product dimensions. In this embodiment, the glass cutting device is a longitudinal slicing machine. In other embodiments, the glass cutting device may be a transverse slicing machine or other types of cutting devices; no specific limitations are specified here.

[0034] like Figures 1-3 As shown, the glass cutting device includes an anvil 1 and a scribing mechanism. A support platform 11 for supporting glass 10 is provided at the top of the anvil 1. The scribing mechanism includes a blade holder 2 and a cutting blade 3. The blade holder 2 is positioned above the anvil 1, and the cutting blade 3 is slidably mounted on the blade holder 2 along the scribing direction (front-back direction in the figure). The cutting blade 3 is configured to press the glass 10 against the support platform 11 and slide along the scribing direction to scribble lines on the upper surface of the glass 10. When the glass 10 is conveyed to the anvil 1 by a conveyor belt, the anvil 1 has a protruding support platform 11 to support the glass 10. Along the height direction (up-down direction in the figure), the blade holder 2 and the cutting blade 3 are located above the anvil 1, and the cutting blade 3 and the support platform 11 are directly opposite each other along the height direction. The cutting blade 3 presses against the upper surface of the glass 10 to press the glass 10 firmly against the support platform 11. The blade holder 2 is equipped with a slide rail extending along the scribing direction. The motor of the scribing mechanism drives the cutter 3 to slide along the slide rail to scribble lines on the upper surface of the glass 10. Along the left-right direction in the figure, the area between the right edge of the glass 10 and the scribing line drawn by the cutter 3 is the bait section 101 of the glass 10, which is the excess material that needs to be broken off and removed. Finally, the breaking mechanism of the glass cutting device breaks off the bait section 101 along the scribing line on the upper surface of the glass 10. Since both the scribing mechanism and the breaking mechanism are existing technologies for glass cutting devices, their specific structures and working processes will not be described in detail.

[0035] Existing glass cutting devices generate dust when they scribing and breaking glass 10, causing the dust to float or adhere to the upper and lower surfaces of glass 10, affecting product quality.

[0036] To solve the above problems, such as Figures 1-3As shown, the glass cutting device also includes a dust-collecting mechanism and two dust-blocking plates 4. The dust-collecting mechanism is used to collect dust from the upper and lower surfaces of the glass 10. One end of each dust-blocking plate 4 along the height direction is respectively disposed on the anvil 1 and the knife holder 2. Both dust-blocking plates 4 are located on the side of the cutter 3 away from the bait section 101 of the glass 10. The dust-blocking plates 4 extend at least to both ends of the glass 10 along the marking direction, and the other ends of each dust-blocking plate 4 along the height direction abut against the upper and lower surfaces of the glass 10, respectively. During the process of the cutter 3 marking the upper surface of the glass 10 and subsequently breaking the bait section 101, dust adheres to the upper and lower surfaces of the glass 10. The cutting table 1 and the knife holder 2 are each equipped with a dust baffle 4. The dust baffle 4 is located on the side of the cutter 3 away from the feed part 101 of the glass 10. The other ends of the two dust baffles 4 along the height direction respectively abut against the upper and lower surfaces of the glass 10 to prevent dust from spreading to the upper and lower surfaces of the glass 10 over a large area. This reduces the range of dust adhering to the upper and lower surfaces of the glass 10, making it easier to remove dust quickly through the dust collection mechanism. This improves the dust removal effect of the glass cutting device, thereby improving the cleanliness of the upper and lower surfaces of the glass 10 and the product quality.

[0037] like Figure 1 As shown, the two dust baffles 4 are positioned opposite each other along the height direction. By positioning the two dust baffles 4 opposite each other, they are pressed against the upper and lower surfaces of the glass 10 at the same position, thereby clamping and fixing the glass 10, further improving the stability of the glass 10, preventing the glass 10 from breaking during the marking and breaking process, and improving the stability and cutting quality of the glass 10.

[0038] It should be noted that the dust baffle 4 is a rubber sheet, with the other ends of the two rubber sheets elastically abutting against the upper and lower surfaces of the glass 10, respectively, along the height direction. Because the dust baffle 4 is made of rubber, not only is its cost reduced, but it also provides a certain degree of elasticity, ensuring that the contact between the dust baffle 4 and the upper and lower surfaces of the glass 10 is elastically pressed, preventing scratches or other damage to the glass 10 and protecting the quality of its surfaces. Simultaneously, the rubber sheets also provide good support, clamping the glass 10 securely between the two rubber sheets.

[0039] like Figure 1 As shown, the anvil 1 has a first slot 12, and the knife holder 2 has a second slot 21. One dust baffle 4 is engaged in the first slot 12 at one end along its height, and the other dust baffle 4 is engaged in the second slot 21 at one end along its height. The two dust baffles 4 are respectively engaged and installed on the corresponding anvil 1 and knife holder 2 through the first slot 12 and the second slot 21, realizing the detachable installation of the dust baffles 4, improving the efficiency of dust baffle installation and removal, and making the replacement and maintenance of the dust baffles 4 simple and easy.

[0040] It should be noted that an antistatic film 41 is affixed to the side of the dust baffle 4 facing the cutter 3. By affixing the antistatic film 41, the side of the dust baffle 4 facing the cutter 3 has a good antistatic effect, preventing dust from adhering to the side of the dust baffle 4, so that all dust is removed by the dust collection mechanism, further improving the dust removal effect.

[0041] like Figure 1 As shown, both the anvil 1 and the knife holder 2 are equipped with an antistatic mechanism 5, which is located on the side away from the bait section 101 of the glass 10. By setting the antistatic mechanism 5, the upper and lower surfaces of the glass 10 have an antistatic effect, preventing glass dust from adhering to the upper and lower surfaces of the glass 10, and allowing all dust to be removed by the dust collection mechanism, further improving the dust removal effect.

[0042] In this embodiment, the static eliminator 5 is a windless ion bar. Windless ion bars are energy-saving, environmentally friendly, and do not disperse dust. Two windless ion bars are arranged corresponding to the upper and lower sides of the glass 10, respectively. Each windless ion bar has multiple discharge needles capable of releasing electrical charges. The positive and negative charges released by the discharge needles are emitted onto the upper or lower surface of the glass 10, ensuring that the upper and lower surfaces of the glass 10 can fully contact the positive and negative charges. This guarantees that the static electricity on the upper and lower surfaces of the glass 10 is reduced or completely eliminated, thereby reducing or eliminating the situation where dust adheres to the upper and lower surfaces of the glass 10 due to static electricity, further improving the dust removal effect.

[0043] like Figure 1 and Figure 2 As shown, the dust collection mechanism includes an exhaust fan and multiple lower suction pipes 6. The anvil 1 has multiple lower suction ports spaced apart along the scribed line direction. The exhaust fan is connected to the multiple lower suction pipes 6, and one end of each lower suction pipe 6 is connected to a corresponding lower suction port. Specifically, the multiple lower suction pipes 6 are installed spaced apart within the anvil 1 along the scribed line direction. When the glass 10 is scribed or broken, the exhaust fan is activated, and dust generated on the lower surface of the glass 10 is sucked into the lower suction pipes 6 through the multiple lower suction ports to remove dust from the lower surface of the glass 10.

[0044] like Figure 1 and Figure 3 As shown, the dust collection mechanism also includes multiple upper suction pipes 7, and the blade holder 2 is provided with multiple upper suction ports at intervals along the scribing direction. The exhaust fan is connected to the multiple upper suction pipes 7, and one end of each upper suction pipe 7 is connected to a corresponding upper suction port. Specifically, the multiple upper suction pipes 7 are installed at intervals within the blade holder 2 along the scribing direction. When the glass 10 is scribed or broken, the exhaust fan is turned on, and the dust generated on the upper surface of the glass 10 is sucked into the upper suction pipes 7 through the multiple upper suction ports to achieve dust removal from the upper surface of the glass 10.

[0045] It should be noted that the vacuuming mechanism also includes a dust collection box 8, with the other ends of the multiple lower suction pipes 6 and the other ends of the multiple upper suction pipes 7 all connected to the dust collection box 8. By setting up the dust collection box 8, all the dust sucked in by the lower suction pipes 6 and upper suction pipes 7 is collected into the dust collection box 8, preventing dust from clogging the lower suction pipes 6 or upper suction pipes 7. At the same time, the lower suction pipes 6 and upper suction pipes 7 share the same dust collection box 8, simplifying the structure of the vacuuming mechanism, reducing costs, and achieving a compact installation of the vacuuming mechanism.

[0046] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
