Description

Technical fields:

[0001] This utility model relates to a glass rod cutting device, belonging to the field of glass rod processing technology. Background technology:

[0002] Optical glass lenses are transparent media composed of two refractive surfaces, also known as lenses. Optical glass lenses provide clear images, are not easily scratched, and can absorb some ultraviolet rays. Different materials have different characteristics in terms of UV resistance, scratch resistance, and image quality. Currently, in the production of optical glass lenses, a glass rod is generally first cut into multiple glass sheets, and then the glass sheets are ground to form the glass lens.

[0003] There are many types of glass rod cutting devices available. For example, Chinese invention patent application publication number CN114603616A, entitled "A Cutting Device for the Production and Processing of Acrylic Glass Rods," discloses a method that uses a flexible, small-area clamping mechanism to hold the acrylic glass rods to be cut in a fully positioned position. This effectively prevents deviation during the cutting process and also prevents damage to the acrylic glass rods caused by excessive clamping force, thus enhancing practicality. It has advantages such as simplified structure, high degree of automation, and wide applicability.

[0004] However, the above-mentioned patents have the following problems when used:

[0005] 1. In the above-mentioned patent, a cutter is used to cut the glass rod from top to bottom. In actual cutting, due to the properties of the glass itself, the glass rod will crack from the cut end face. If the glass rod is cut in one direction, the cut end face of the glass rod will be large and uneven, affecting subsequent use.

[0006] 2. In the above-mentioned patent, the glass rod is moved by the rotation of the reciprocating screw. In actual use, dust and impurities generated during the cutting of the glass rod can easily fall from the worktable into the screw. This can reduce the accuracy of the screw or even cause the screw to jam, resulting in damage to the device. Summary of the Invention:

[0007] The technical problem to be solved by this utility model is to provide a glass rod cutting device to solve the problems faced in the industry.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a glass rod cutting device for cutting glass rods, including a bottom support frame, a support base plate provided on the upper surface of the bottom support frame, a portal frame provided on the left side of the upper surface of the support frame, a feeding roller structure provided on the right side of the portal frame, a discharging roller structure provided on the left side of the portal frame, a clamping structure provided on the portal frame, a glass rod clamping and conveying structure provided on the side of the feeding structure, and a cutting structure provided on the left side of the portal frame.

[0013] Preferably, the cutting structure includes cutting support plates placed on both sides of the discharge roller structure. The cutting support plates are provided with parallel linear guide rails, and sliders are provided on the linear guide rails. A movable support plate is provided on the sliders, and a cutting motor is provided on the movable support plate. A cutting blade is provided at the end of the motor shaft of the cutting motor. The cutting support plates are also provided with a cutting motor moving cylinder, and the motor shaft of the cutting motor moving cylinder is connected to the cutting motor.

[0014] Preferably, the right end of the support plate is provided with a side baffle, the side baffle is provided with a threaded hole, and a positioning screw is provided in the threaded hole.

[0018] Compared with the prior art, the advantages of this utility model are as follows: When in use, the glass rod to be cut is placed on the feeding roller, and the glass rod is moved to the set position by the glass rod clamping and conveying structure. The glass rod is pressed down by the clamping structure, and the cutting motor is driven by the front and rear moving cylinder to move relative to each other. The cutting blade on the cutting motor cuts the glass rod, thereby realizing bidirectional cutting of the glass rod. Bidirectional cutting reduces the depth and width of the crack at the cut end of the glass rod and improves the cutting effect of the glass rod. At the same time, this patent adopts roller transmission, which solves the problem that when the glass rod is moved by the lead screw in the prior art, the lead screw is easily contaminated by impurities, resulting in a decrease in accuracy or damage, thus reducing production costs.

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0027] like Figures 1 to 5 The illustrated glass rod cutting device, used for cutting glass rod 1, includes a bottom support frame 2, a support base plate 3 on the upper surface of the bottom support frame 2, a portal frame 4 on the left side of the upper surface of the support base plate 3, a feeding roller structure 5 on the right side of the portal frame 4, a discharge roller structure 6 on the left side of the portal frame 4, a clamping structure 7 on the portal frame 4, a glass rod clamping and conveying structure 8 on the side of the feeding roller structure 5, and a cutting structure 9 on the left side of the portal frame 4.

[0028] To facilitate the movement of the glass rod 1, the feeding roller structure 5 further includes multiple roller bases 501, with parallel roller mounting seats 502 on each roller base 501, multiple feeding rollers 503 between the roller mounting seats 502, and a discharge gap 504 between the feeding rollers 503.

[0029] To facilitate the movement of the cut glass rod 1, the discharge roller structure 6 further includes a U-shaped roller support plate 601, on which a set of parallel roller mounting plates 602 are provided, and multiple discharge rollers 603 are arranged between the roller mounting plates 602.

[0030] In order to press the glass rod 1, the pressing structure 7 further includes a pressing cylinder 701, which is installed on the top of the portal frame 4. The cylinder shaft of the pressing cylinder 701 passes through the portal frame 4 and extends into the portal frame 4. A glass rod pressing plate 702 is provided on the cylinder shaft of the pressing cylinder 701.

[0031] In order to move the glass rod 1, the glass rod clamping and conveying structure 8 further includes a side support 801, a front-to-back moving cylinder 802 is provided on the side support 801, an L-shaped transition plate 803 is provided on the cylinder shaft of the front-to-back moving cylinder 802, a clamping double-headed cylinder 804 is provided on the L-shaped transition plate 803, and a clamping plate 805 is provided on the cylinder shaft of the clamping double-headed cylinder 804, with the glass rod 1 located between the clamping plates 805.

[0032] To cut the glass rod 1, the cutting structure 9 further includes cutting support plates 901 respectively placed on both sides of the discharge roller structure 6. The cutting support plates 901 are provided with parallel linear guide rails 902. The linear guide rails 902 are provided with sliders 903. The sliders 903 are provided with movable support plates 904. The movable support plates 904 are provided with cutting motors 905. The end of the motor shaft of the cutting motor 905 is provided with a cutting blade 906. The cutting support plates 901 are also provided with a cutting motor moving cylinder 907. The cylinder shaft of the cutting motor moving cylinder 907 is connected to the movable support plate 904.

[0033] To further position the glass rod 1, a side baffle 301 is provided at the right end of the support plate 3, and a threaded hole 302 is provided on the side baffle 301, in which a positioning screw 303 is provided.

[0034] To prevent impurities from flowing, the support plate 3 is further provided with a surrounding barrier 304.

[0035] To further enhance safety, a motor protective cover 10 is provided on the side of the gantry bracket 4, and the cutting motor 905 is located in the motor protective cover 10.

[0036] To further enhance the overall strength of the device, the bottom support frame 2 is further composed of multiple crossbeams 201 and columns 202 connected together.

[0037] In use, the positioning screw 303 is engaged in the threaded hole 302. The length of the positioning screw 303 is adjusted according to the length of the glass rod 1 to be cut. The glass rod 1 to be cut is placed on the feed roller 503, and one end of the glass rod 1 is placed against the adjusting positioning screw 303.

[0038] The forward and backward movement cylinder 802 of the glass rod clamping and conveying structure 8 is activated. The forward and backward movement cylinder 802 drives the L-shaped transition plate 803 to move, while the clamping double-head cylinder 804 is fixed on the L-shaped transition plate 803. At the same time, the two cylinder shafts of the clamping double-head cylinder 804 are located on both sides of the glass rod 1. In this way, the forward and backward movement cylinder 802 drives the clamping double-head cylinder 804 to move along the front and back of the glass rod 1. At the same time, the clamping double-head cylinder 804 is activated, clamping the glass rod 1. Then, the forward and backward movement cylinder 802 drives the clamping double-head cylinder 804 and the clamped glass rod 1 to move to the set position.

[0039] Once the glass rod 1 is moved to the set position, the clamping cylinder 701 is activated, which presses the glass rod pressure plate 702 onto the glass rod 1, thereby fixing the glass rod 1.

[0040] Once the glass rod 1 is fixed, the cutting motor 905 is started, which drives the cutting blade 906 to rotate. At the same time, the cutting motor moving cylinder 907 is started, which drives the moving support plate 904 to slide back and forth. The cutting motor 905 is mounted on the moving support plate 904. In this way, the cutting motor moving cylinder 907 drives the cutting motor 905 to move back and forth, thereby achieving the purpose of cutting the glass rod 1 by the cutting blade 906.

[0041] After the cutting is completed, the glass rod 1 on the left side, which has been cut into segments, is pushed against the discharge roller 603 by the next glass rod 1 to be cut, thereby achieving the purpose of moving the glass rod 1.

[0042] In this patent, when the glass rod 1 is pressed by the glass rod pressure plate 702, the clamping double-headed cylinder 804 will release from the glass rod 1, and then the back-and-forth moving cylinder 802 will drive the clamping double-headed cylinder 804 to move to the set position, in preparation for the next clamping and movement of the glass rod 1.

[0043] In this patent, when cutting the glass rod 1, two cutting motors 905 drive the cutting blades 906 to cut the glass rod 1 simultaneously, achieving bidirectional cutting of the glass rod 1. Due to the fragile nature of glass, when the two cutting blades 906 cut the glass rod 1, it is not necessary to completely sever it. The glass rod 1 will crack from the center when it is cut to a set position. This can minimize the depth and width of the crack, thus solving the problem in the prior art where the cut end face of the glass rod 1 is deeply cracked and the crack surface is large after unidirectional cutting. At the same time, this patent uses roller transmission, which solves the problem in the prior art where the lead screw is easily contaminated by impurities, leading to a decrease in accuracy or damage when the glass rod is moved by the lead screw. This improves production efficiency and reduces production costs.

[0044] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
