Description

Technical Field

[0001] The present invention relates to the technical field of glass cutting, and specifically to a glass cutting device with an adaptive adjustment structure. Background Art

[0002] With the rapid development of the biomedical, optical instrument, and new energy industries, the processing accuracy requirements for glass products have been raised to the micron-level standard, especially in the processing of high-precision products such as pharmaceutical glass bottles and optical lenses;

[0003] For example, a glass bottle cutting device described in patent number CN220241072U fixes the glass bottle on the mounting block by setting a clamping mechanism, and uses the cooperation of a lead screw and a nut seat to drive the part of the glass bottle to be cut to move to a position corresponding to the cutting grinding wheel to perform the cutting operation; however, there are still certain defects in the use of this device:

[0004] (1) Using a single-axial clamping mechanism, only one-way positioning of the glass bottle is achieved through a linear guide rail, which easily leads to insufficient stability of the glass bottle during cutting;

[0005] (2) Only one group of glass bottles can be processed at a time. When processing glass bottles of the same batch, continuous cutting operations are likely to cause deviation in the cutting position, which easily affects the cutting efficiency of the glass bottles;

[0006] (3) Using a cemented carbide tool for cutting, this method will generate a certain amount of burrs on the cutting surface of the glass bottle and glass products after cutting. Usually, additional grinding devices need to be used for subsequent processing, and it is difficult to automatically process the cutting surface of the glass bottle, resulting in insufficient automation. Summary of the Invention

[0007] The object of the present invention is to not only meet the clamping requirements of glass bottles with various diameters through multi-party joint clamping of glass bottles, but also ensure stability during cutting and reduce vibration errors; in addition, by adopting the method of coordinated operation of dynamic cutting and grinding, not only can batch cutting processing of glass bottles be achieved, reducing the cutting deviation between glass bottles, but also the cutting surface can be polished in a timely manner, reducing downtime and effectively improving the cutting efficiency of special-shaped workpieces such as glass bottles.

[0008] The object of the present invention can be achieved through the following technical solutions: a glass cutting device with an adaptive adjustment structure, including an operation frame, a positioning frame is fixedly installed at one end inside the operation frame, a placing table is fixedly installed at the center of one side of the positioning frame, and a number of groups of semi-circular card slots are equidistantly arranged on the top surface of the placing table. A two-way positioning mechanism is arranged at the end of the operation frame away from the positioning frame. A first chute and a second chute are respectively arranged inside the positioning frame, and a dynamic cutting mechanism is arranged at the rear end of the placing table at the bottom of the positioning frame.

[0009] Among them, the bidirectional positioning mechanism includes a sliding frame, the sliding frame is fixedly installed inside the positioning frame, and a first motor is arranged on the inner wall of the rear end of the sliding frame. A spiral rod is fixedly installed at the output end of the first motor. Cross plates are respectively arranged at the front and rear ends of the bottom surface of the sliding frame. A number of T-shaped abutting plates are fixedly installed on the opposite surfaces of the two cross plates.

[0010] Furthermore, the rear cross plate is fixedly connected to the bottom surface of the sliding frame. At the end of the top surface of the front cross plate, a spiral sleeve frame is fixedly installed, and the spiral sleeve frame is threadedly sleeved outside the spiral rod.

[0011] Furthermore, at the center of the inner walls on both sides of each semi-circular card slot, a wedge-shaped abutting rod is symmetrically penetrated. A block is fixedly installed at the center of the outer part of the wedge-shaped abutting rod. A spring group coil is jointly wound between the block and the inner wall of the semi-circular card slot on the outer part of the wedge-shaped abutting rod.

[0012] Furthermore, the dynamic cutting mechanism includes a first cylinder and a second motor. The first cylinder is arranged on the inner wall of the front end of the first chute, and the second motor is arranged on the inner wall of the rear end of the second chute. The output end of the first cylinder at the rear is fixedly installed with a slider through a push rod, and the bottom end of the slider extends to the bottom of the first chute. A rack is horizontally penetrated at the bottom end of the slider inside the first chute.

[0013] Furthermore, a feeding long roller is fixedly installed at the output end of the second motor, and the bottom end of the feeding long roller extends to the bottom of the second chute and meshes with the top surface of the rack. A cutting assembly is arranged at one end of the top surface of the rack close to the feeding long roller.

[0014] Furthermore, the cutting assembly includes a positioning plate fixedly installed on the top surface of the rack on one side of the rear border. A dual-axis motor is arranged at one end of the front surface of the positioning plate. A cutting knife wheel is fixedly installed on the front output shaft of the dual-axis motor. One end of the cutting knife wheel extends outside the rack.

The cutting wheel is used to cut the glass bottle, and the grinding disc is used to finely repair the cutting surface to improve the edge flatness. It can not only achieve batch cutting of glass bottles, reduce the cutting deviation between glass bottles, but also perform grinding treatment on the cutting surface in a timely manner, reduce the downtime, and effectively improve the cutting efficiency of special-shaped workpieces such as glass bottles.

[0027] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1: Please refer to Figures 1-4 As shown in the figure, a glass cutting device with an adaptive adjustment structure includes an operating frame 1. At one end inside the operating frame 1, a positioning frame 2 is fixedly installed. At the center of one side of the positioning frame 2, a placing table 3 is fixedly installed. On the top surface of the placing table 3, a number of groups of semi-circular card slots 4 are arranged at equal intervals. At the center of the inner walls on both sides of each group of semi-circular card slots 4, wedge-shaped abutting rods 401 are symmetrically penetrated. At the center of the outer part of the wedge-shaped abutting rod 401, a block 402 is fixedly installed. Between the block 402 and the inner wall of the semi-circular card slot 4 on the outer part of the wedge-shaped abutting rod 401, a spring coil group 403 is wound together;

[0029] At the end of the operating frame 1 away from the positioning frame 2, a two-way positioning mechanism 5 is provided. Among them, the two-way positioning mechanism 5 includes a sliding frame 51. The sliding frame 51 is fixedly installed inside the positioning frame 2. At the inner wall of the rear end of the sliding frame 51, a first motor 52 is provided. At the output end of the first motor 52, a spiral rotating rod 53 is fixedly installed. At the front and rear ends of the bottom surface of the sliding frame 51, cross plates 54 are respectively provided. On the opposite surfaces of the two cross plates 54, a number of groups of T-shaped abutting plates 55 are fixedly installed. The rear cross plate 54 is fixedly connected to the bottom surface of the sliding frame 51. At the end of the top surface of the front cross plate 54, a spiral sleeve frame 56 is fixedly installed. The spiral sleeve frame 56 is threadedly sleeved on the outer part of the spiral rotating rod 53;

[0030] First, place several glass bottles on the surface of the table 3 and clamp them in the corresponding semicircular slots 4, with the head and tail ends of the glass bottles extending to the outside of the semicircular slots 4. The glass bottles will contact the wedge-shaped push rod 401, causing the wedge-shaped push rod 401 to contract into the semicircular slots 4. At this time, the spring coil 403 is deformed by the force. When the glass bottles are completely clamped in the semicircular slots 4, the spring coil 403 will reset and drive the clamping block 402 to contact and clamp the glass bottles, thereby limiting and fixing the glass bottles to prevent the glass bottles from deflecting and rolling during the pushing process.

[0031] Then, the motor 1 52 is started to drive the spiral rod 53 to rotate. Since the spiral sleeve 56 is threadedly sleeved on the outside of the spiral rod 53, and the rear end of the spiral sleeve 56 is fixedly connected to the front cross plate 54, when the spiral rod 53 rotates, the spiral sleeve 56 will drive the front cross plate 54 to move back and forth inside the sliding frame 51, thereby causing the front cross plate 54 to drive the T-shaped abutment plate 55 installed on its surface to contact and push the front end of the glass bottle until the rear end of the glass bottle is pressed against the corresponding T-shaped abutment plate 55, thereby achieving the clamping of the front and rear ends of the glass bottle and simultaneously pushing the rear end of the glass bottle to the cutting position for cutting.

[0032] It can not only quickly limit and fix the glass bottle, but also push the glass bottle back and forth to keep it stable during cutting, avoiding deviation or shaking of the glass bottle during cutting, thereby improving the accuracy and efficiency of glass cutting.

[0033] Example 2: Please refer to Figure 2 、 Figure 5 - Figure 6 As shown, the interior of the positioning frame 2 is respectively provided with a chute 1 201 and a chute 2 202, and the bottom of the positioning frame 2 is located at the rear end of the storage table 3 and is provided with a dynamic cutting mechanism 6. The dynamic cutting mechanism 6 includes a cylinder 1 61 and a motor 2 62. The cylinder 1 61 is provided at the inner wall of the front end of the chute 1 201, and the motor 2 62 is provided at the inner wall of the rear end of the chute 2 202.

[0034] A slider 63 is fixedly installed at the rear output end of the cylinder 1 61 through a push rod, and the bottom end of the slider 63 extends to the bottom of the chute 1 201. A rack 64 is provided transversely through the slider 63 at the bottom end of the chute 1 201. A long material transfer roller 65 is fixedly installed at the output end of the motor 2 62, and the bottom end of the long material transfer roller 65 extends to the bottom of the chute 2 202 and meshes with the top surface of the rack 64. A cutting assembly 66 is provided on the top surface of the rack 64 near the end of the long material transfer roller 65.

[0035] The cutting assembly 66 includes a positioning plate 661 fixedly installed on the top surface of the rack 64 on one side of the rear end frame. At one end of the front face of the positioning plate 661, there is a dual-axis motor 662, and a cutting wheel 663 is fixedly installed on the front output shaft of the dual-axis motor 662. One end of the cutting wheel 663 extends outside the rack 64, and the rear output shaft of the dual-axis motor 662 extends to the rear of the positioning plate 661 and is fixedly installed with a transmission wheel 664;

[0036] During the specific cutting process: First, determine the cutting position of the glass bottle body, start the first cylinder 61 to drive the push rod to expand and contract, thereby driving the slider 63 to slide back and forth inside the first chute 201. At this time, the rack 64 and the cutting assembly 66 at the bottom end of the slider 63 will move accordingly until the cutting wheel 663 and the cutting point of the glass bottle are on the same plane;

[0037] Then, start the second motor 62 to drive the feeding long roller 65 to rotate. Since the feeding long roller 65 is meshed and driven with the rack 64, the feeding long roller 65 drives the cutting assembly 66 to move linearly along the track of the rack 64 and continuously approach the side-by-side glass bottles. During the movement, start the dual-axis motor 662 to drive the cutting wheel 663 to rotate at a high speed, thereby precisely cutting the glass bottle conveyed to the cutting position.

[0038] In addition, by adjusting the expansion and contraction length of the first cylinder 61 and the rotation speed of the second motor 62, precise control of the cutting position and cutting speed can be achieved, thereby meeting the cutting requirements of glass bottles of different specifications. The design of this dynamic cutting mechanism 6 not only improves the automation degree of glass cutting but also greatly enhances the cutting efficiency and accuracy;

[0039] It should be noted that a shaft rod 665 is movably penetrated inside the positioning plate adjacent to the dual-axis motor 662, and a transmission wheel 664 is also provided at the rear end of the shaft rod 665. A transmission belt is sleeved between the two transmission wheels 664. A grinding disc 666 is fixedly installed at the front end of the shaft rod 665, and the grinding disc 666 is offset from the cutting wheel 663 in the front and rear directions.

[0040] The transmission wheel 664 on the rear output shaft of the dual-axis motor 662 will rotate synchronously, and drive the transmission wheel 664 on the shaft rod 665 to rotate through the transmission belt, thereby driving the grinding disc 666 to rotate; the grinding disc 666 moves synchronously with the cutting wheel 663. After each group of glass bottles is cut, the grinding disc 666 performs a slight grinding treatment on the cutting surface of the glass bottle to remove burrs or uneven parts that may be generated during the cutting process, ensuring the smoothness and flatness of the cutting edge. This design not only improves the quality of the cut glass but also reduces the workload of subsequent manual grinding, further enhancing the overall production efficiency;

[0041] It is worth noting that when cutting flat glass, the above steps can also be used for dynamic cutting.

[0042] Working principle: When the present invention is in use, first, several glass bottles are placed on the surface of the storage platform 3 and respectively clamped in the corresponding semicircular slots 4, and the head and tail ends of the glass bottles extend to the outside of the semicircular slots 4 respectively. The glass bottles will resist the wedge-shaped push rod 401, causing the wedge-shaped push rod 401 to shrink into the semicircular slots 4. At this time, the spring coil 403 is deformed by the force. When the glass bottles are completely clamped in the semicircular slots 4, the spring coil 403 will reset and drive the clamping block 402 to resist and clamp the glass bottles, thereby limiting and fixing the glass bottles to prevent the glass bottles from deflecting and rolling during the pushing process.

[0043] Subsequently, the motor 1 52 is started to drive the spiral rotating rod 53 to rotate, and the spiral sleeve frame 56 drives the front horizontal plate 54 to move back and forth inside the sliding frame 51, thereby causing the front horizontal plate 54 to drive the T-shaped abutment plate 55 installed on its surface to contact and push the front end of the glass bottle until the rear end of the glass bottle is pressed against the corresponding T-shaped abutment plate 55, thereby clamping the front and rear ends of the glass bottle and pushing the rear end of the glass bottle to the cutting position for cutting.

[0044] Next, by adjusting the telescopic length of cylinder 1 61, the slider 63 is forced to drive the rack 64 and the cutting assembly 66 to move to the predetermined cutting line of the flat glass, and then the motor 2 62 is started. The long material transfer roller 65 will drive the rack 64 and the cutting assembly 66 to move in a straight line along the predetermined cutting line. At the same time, the dual-axis motor 662 is started, and the cutting wheel 663 rotates at high speed, thereby accurately cutting the flat glass. During the cutting process, after the cutting is completed, the grinding disc 666 will slightly grind the cutting edge to remove possible burrs or uneven parts to ensure that the cutting edge is smooth and flat.

[0045] The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to specific embodiments. Obviously, many modifications and variations are possible based on the contents of this specification. These embodiments are selected and described in detail in this specification to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention.
