Description
Technical Field
[0001] This utility model relates to the field of glass cutting technology, specifically to a multi-angle adjustable glass cutting device. Background Technology
[0002] Glass is an amorphous inorganic non-metallic material, generally made from a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, with the addition of a small amount of auxiliary raw materials. After the glass is produced, it needs to be cut by a glass cutting device to meet the requirements.
[0003] To facilitate cutting different shapes, existing glass cutting devices typically feature an adjustable blade structure. Specifically, a motor drives the shaft to rotate, which in turn rotates the cutting blade, allowing for easy angle adjustment. While this adjustable-angle glass cutting device allows for convenient blade angle adjustment, the weight of the blade and other components makes the centrifugal force generated during rotation prone to causing deformation of the motor shaft.
[0004] To address these issues, we designed a multi-angle adjustable glass cutting device. Utility Model Content

The first cylinder is fixedly installed on one side of the crossbeam, and its driving end extends into the mounting groove and is fixedly connected to the slider.
[0013] Furthermore, the cutting component includes a protective cover, the top of which is fixedly connected to the bottom of the slider.

[0016] Compared with the prior art, the beneficial effects of this utility model are: during the rotation of the crossbeam, the crossbeam will drive the support column and the limiting head to make arc movements in the annular groove, which can share the tensile force brought by the centrifugal force of the motor drive shaft, thereby helping to reduce the problem of deformation of the motor drive shaft and helping to extend the service life of the motor drive shaft.
[0017] Compared with the prior art, the beneficial effects of this utility model are: during the movement of the limiting head, the limiting head will drive the ball to roll in the annular groove, which can change the sliding friction between the limiting head and the top wall of the annular groove into rolling friction, reducing the frictional force of the limiting head in the annular groove, thereby reducing the frictional wear of the limiting head.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4This utility model provides a technical solution: a multi-angle adjustable glass cutting device, including a base 1, a support frame 2 is provided on the top of the base 1, the support frame 2 is spaced from the base 1, an electric push rod 3 is provided on the top of the support frame 2, the driving end of the electric push rod 3 slides through the support frame 2 and is provided with a motor 4, the drive shaft of the motor 4 is provided with a cross frame 5, the bottom of the cross frame 5 is provided with a cutting part 6, a limiting part 7 is fixedly sleeved on the motor 4, a support column 8 is provided on the top of the cross frame 5, a limiting head 9 is provided on the top of the support column 8, an annular groove 10 is opened at the bottom of the limiting part 7, and the support column 8 and the limiting head 9 are slidably inserted into the annular groove 10;
[0026] The cross frame 5 is provided with a driving component for driving the cutting piece 6. The driving component includes a mounting groove 14, a slider 15 and a first cylinder 16. The mounting groove 14 is opened at the bottom of the cross frame 5. The slider 15 is slidably inserted into the mounting groove 14 and the bottom of the mounting groove 14 is connected to the cutting piece 6. The first cylinder 16 is fixedly installed on one side of the cross frame 5 and the driving end extends into the mounting groove 14 and is fixedly connected to the slider 15.
[0027] The cutting component 6 includes a protective cover 17, the top of which is fixedly connected to the bottom of the slider 15. A blade 18 is rotatably disposed inside the protective cover 17, with a portion of the blade 18 located outside the protective cover 17. A motor 19 is fixedly mounted on the front side of the protective cover 17, and the drive shaft of the motor 19 extends rotatably into the protective cover 17 and is fixedly inserted into the blade 18.
[0028] In practice, by turning on the motor 4, the drive shaft of the motor 4 can drive the crossbeam 5 and the cutting piece 6 to rotate, which can easily adjust the cutting angle of the cutting piece 6 to meet different cutting specifications. By turning on the electric push rod 3, the drive end of the electric push rod 3 can extend and drive the crossbeam 5 and the cutting piece 6 to move downward. During this process, the first cylinder 16 and the motor 19 are turned on at the same time, which can cause the drive end of the first cylinder 16 to extend and retract, driving the slider 15 and the cutting piece 6 to slide horizontally along the direction set in the mounting groove 14, and causing the drive shaft of the motor 19 to drive the blade 18 to rotate, which can easily cut the glass sheet. The setting of the fixing groove 24 can not only cut the glass sheet through, but also avoid touching the base 1 and avoid damage to the cutting piece 6.
[0029] During the rotation of the crossbeam 5, the crossbeam 5 will drive the support column 8 and the limiting head 9 to make arc movements within the annular groove 10, which can share the tensile force caused by centrifugal force on the drive shaft of the motor 4, thereby helping to reduce the problem of deformation of the drive shaft of the motor 4 and helping to extend the service life of the drive shaft of the motor 4.
[0030] See Figure 1-4There are two support columns 8, and the number of limiting heads 9 corresponds to the number of support columns 8. The two support columns 8 are symmetrically fixedly installed on the top of the cross frame 5. The arrangement of the two support columns 8 can ensure that the two ends of the top of the cross frame 5 are balanced, thereby further improving the stability of the cross frame 5 during movement.
[0031] See Figure 1-4 The top of the limiting head 9 is rotatably provided with a ball bearing 11, which is rotatably connected in the annular groove 10. The inside and top of the limiting head 9 are respectively provided with a cavity and a limiting port. The ball bearing 11 is rotatably disposed in the cavity and the limiting port, and part of it is located outside the limiting port.
[0032] In specific implementation, based on the above implementation, during the movement of the limiting head 9, the limiting head 9 will drive the ball 11 to roll in the annular groove 10, which can change the sliding friction between the limiting head 9 and the top wall of the annular groove 10 into rolling friction, reducing the frictional force of the limiting head 9 in the annular groove 10, thereby reducing the frictional wear of the limiting head 9.
[0033] See Figure 1-4 There is a gap between the limiting head 9 and the support column 8, and a support spring 12 is provided. A telescopic rod 13 is fixedly installed between the limiting head 9 and the support column 8, and the support spring 12 is movably sleeved on the telescopic rod 13.
[0034] In specific implementation, based on the above implementation, through the cooperation of the support spring 12 and the telescopic rod 13, when dust adheres to the top wall of the annular groove 10, the ball 11 will drive the limit head 9 to compress the support spring 12 and move along the telescopic end of the telescopic rod 13 when it rolls over the dust, thus avoiding the problem of movement interference due to dust obstruction and ensuring the normal rolling of the ball 11.
[0035] See Figure 1-4 Two piston rods 20 are symmetrically fixedly installed on the top of the limiting member 7, and the telescopic ends of the piston rods 20 are fixedly installed on the bottom of the support frame 2. By setting the piston rods 20, the motor 4 and the limiting member 7 can only move along the direction of the telescopic ends of the piston rods 20 when moving up and down, which can improve the stability of the motor 4 and the cross frame 5 when moving up and down.
[0036] See Figure 1-4 It also includes a positioning component, which includes two fixing plates 21. The two fixing plates 21 are symmetrically fixedly installed at both ends of the top of the base 1. A second cylinder 22 is fixedly installed on one side of the fixing plate 21. The driving end of the second cylinder 22 slides through the fixing plate 21 and is provided with an L-shaped plate 23. A fixing groove 24 is opened on the top of the base 1.
[0037] In practice, based on the above implementation, the glass sheet to be cut is placed on two L-shaped plates 23, and then two second cylinders 22 are activated. The driving end of the second cylinders 22 drives the L-shaped plates 23 to move, thereby clamping the glass sheet and ensuring the stability of the glass sheet during the cutting process.
[0038] Working principle: Before use, all electrical components involved in the cutting device need to be connected to an external power source, or a battery pack needs to be installed in an area outside the base 1 that does not obstruct other components. Then, the battery pack is connected to the electrical components via wiring. It is also necessary to avoid the wiring from getting tangled due to the movement of the components. Wiring needs to be buried and planned and organized to provide power to the electrical components, thereby ensuring their normal operation and switching. Since connecting the electrical components to an external power source or setting up a battery pack for power supply are existing technologies and are not problems that need to be solved in the background technology of this manual, they will not be explained in detail.
[0039] In use, first place the glass sheet to be cut on the two L-shaped plates 23, then turn on the two second cylinders 22, so that the driving end of the second cylinders 22 drives the L-shaped plates 23 to move, which can clamp the glass sheet and ensure the stability of the glass sheet during the cutting process.
[0040] By activating motor 4, the drive shaft of motor 4 can drive the crossbeam 5 and the cutting piece 6 to rotate, making it easy to adjust the cutting angle of the cutting piece 6 to meet different cutting specifications. By activating electric push rod 3, the drive end of electric push rod 3 can extend to drive the crossbeam 5 and the cutting piece 6 to move downward. During this process, the first cylinder 16 and motor 19 are activated at the same time, so that the drive end of the first cylinder 16 can extend and retract to drive the slider 15 and the cutting piece 6 to slide horizontally along the direction set in the mounting groove 14, and the drive shaft of motor 19 can drive the blade 18 to rotate, which can easily cut the glass sheet. The setting of the fixing groove 24 can not only cut the glass sheet through, but also avoid touching the base 1 and avoid damage to the cutting piece 6.
[0041] In addition, during the rotation of the crossbeam 5, the crossbeam 5 will drive the support column 8 and the limiting head 9 to make arc movements in the annular groove 10, which can share the tensile force caused by centrifugal force on the drive shaft of the motor 4, thereby helping to reduce the problem of deformation of the drive shaft of the motor 4 and helping to extend the service life of the drive shaft of the motor 4.
[0042] During the movement of the limiting head 9, the limiting head 9 will drive the ball 11 to roll in the annular groove 10, which can change the sliding friction between the limiting head 9 and the top wall of the annular groove 10 into rolling friction, reducing the frictional force of the limiting head 9 in the annular groove 10, thereby reducing the frictional wear of the limiting head 9.
[0043] With the cooperation of the support spring 12 and the telescopic rod 13, when dust adheres to the top wall of the annular groove 10, the ball 11 will drive the limit head 9 to compress the support spring 12 and move along the telescopic end of the telescopic rod 13 when it rolls over the dust, thus avoiding the problem of movement interference due to dust obstruction and ensuring the normal rolling of the ball 11.
[0044] By setting the piston rod 20, the motor 4 and the limiting member 7 can only move along the direction of the extension and retraction end of the piston rod 20 when moving up and down, which can improve the stability of the motor 4 and the crossbeam 5 when moving up and down.
