[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0029] Please see Figure 1-4 This utility model provides a technical solution:
[0030] A glass cutting machine blade gap adjustment mechanism includes a frame 1, a linear guide module 2, and a cutting assembly 3. The cutting assembly 3 is mounted on the frame 1. A platform 11 is provided on the top surface of the frame 1. The platform 11 is composed of multiple partition plates with gaps between them. A collection hopper 12 is provided below the platform 11.
[0031] The linear guide module 2 includes a guide rail and a moving platform 11. The guide rail is installed on both sides of the frame 1, and the moving platform 11 is installed on the guide rail. A lifting module 21 is installed on the moving platform 11. The lifting module 21 includes a gantry frame and a cylinder installed on the top surface of the gantry frame. Guide plates 34 are provided on both sides of the protective cover 31. The guide plates 34 are slidably connected in the gantry frame, and the telescopic end of the cylinder is fixedly connected to the guide plates 34.
[0032] The glass to be cut is placed on the platform 11, which is composed of multiple partitions. The linear guide module 2 is activated. The moving platform 11, which is installed on the guide rails on both sides of the frame 1, can slide smoothly along the guide rail under the drive of the motor according to the position of the glass to be cut, thereby driving the lifting module 21 and the cutting component 3 installed on it to move horizontally and accurately position the glass to the starting position where it needs to be cut.
[0033] This process utilizes the high-precision linear motion characteristics of the linear guide module 2 to ensure the accuracy of the horizontal position adjustment of the cutting component 3.
[0034] Once the cutting assembly 3 is horizontally positioned, the lifting module 21 begins to work. The cylinder in the lifting module 21 is installed on the top surface of the gantry frame, and its telescopic end is fixedly connected to the guide plates 34 on both sides of the protective cover 31.
[0035] According to the glass thickness and cutting requirements, the cylinder is activated. When the cylinder piston rod extends, it pushes the guide plate 34 to slide upward along the gantry, thereby driving the protective cover 31 and the internal cutting assembly 3 to rise as a whole.
[0036] When the cylinder piston rod retracts, the guide plate 34 drives the cutting assembly 3 to descend, thereby adjusting the vertical height of the cutting assembly 3, initially determining the gap between the blade and the glass, completing the coarse adjustment of the blade gap, and at this time the glass cutting operation can begin.
[0037] During the cutting process, since the platform 11 is composed of multiple partitions with gaps between them, the glass to be cut can be placed on the platform 11.
[0038] Platform 11 provides a supporting surface for placing the glass, and the gaps between the partitions may help the debris fall off during the glass cutting process without affecting the cutting operation.
[0039] During the cutting process, the debris will fall through the gaps between the partition plates of platform 11 and eventually fall into the collection hopper 12 below platform 11, which facilitates the collection and cleaning of debris and keeps the working environment clean.
[0040] The cutting assembly 3 includes a drive motor, a protective cover 31, and a cutting shaft 32 fixedly connected to the output shaft of the drive motor. The cutting shaft 32 is rotatably connected in the protective cover 31. A main blade 4 is provided on the cutting shaft 32. A connection port 33 is provided on the cutting shaft 32. There are two connection ports 33, which are symmetrically arranged on both sides of the main blade 4. An auxiliary blade 41 is slidably connected in the connection port 33. A bidirectional screw 5 is rotatably connected in the cutting shaft 32. The two auxiliary blades 41 are respectively threaded to both sides of the bidirectional screw 5.
[0041] When the drive motor starts, its output shaft drives the cutting shaft 32 to rotate in the protective cover 31.
[0042] During the glass cutting process, the main blade 4 and the auxiliary blade 41 rotate at high speed. The protective cover 31 can prevent the operator from accidentally coming into contact with the rotating blades, avoid safety accidents such as cuts, and ensure the personal safety of the operator.
[0043] Furthermore, glass shards or debris may be generated when cutting glass, and the protective cover 31 can also prevent these shards from flying around, reducing damage to the working environment and injury to personnel.
[0044] Since the main blade 4 is fixed on the cutting shaft 32, the main blade 4 will rotate together with the cutting shaft 32 to perform the glass cutting operation.
[0045] A connection port 33 is provided on the cutting shaft 32, and the auxiliary blade 41 is slidably connected in the connection port 33. A bidirectional screw 5 is rotatably connected in the cutting shaft 32, and the two auxiliary blades 41 are respectively threaded to both sides of the bidirectional screw 5.
[0046] When it is necessary to adjust the gap between the main blade 4 and the auxiliary blade 41, or the gap between the two auxiliary blades 41, rotate the bidirectional screw 5.
[0047] The bidirectional screw 5 has two sections of threads with opposite directions of rotation. When the bidirectional screw 5 rotates clockwise, the two auxiliary blades 41 that are threaded to both sides of the bidirectional screw 5 will move towards each other along the connection port 33, that is, the gap between the main blade 4 and the auxiliary blade 41 and the gap between the two auxiliary blades 41 become smaller.
[0048] When the bidirectional screw 5 rotates counterclockwise, the two auxiliary blades 41 will move in opposite directions along the connection port 33, and the gap will increase.
[0049] By adjusting the gap between the main blade 4 and the auxiliary blade 41, as well as the gap between the two auxiliary blades 41, the combination of cutting blades and the cutting width can be flexibly adjusted according to the glass of different thicknesses, hardnesses and cutting requirements.
[0050] For thicker glass, the gap between the blades can be increased to improve cutting efficiency and quality; for thinner glass, the gap can be reduced to prevent the glass from breaking.
[0051] By adjusting the blade gap, the cutting force can be distributed more rationally during the cutting process, avoiding excessive wear of any one blade, thereby extending the service life of the entire blade assembly and reducing the cost of replacing blades.
[0052] A proper blade gap can make the cutting process smoother, reduce vibration and chipping of the glass during cutting, improve cutting accuracy and surface quality, and make the cut glass edges smoother and neater.
[0053] The aforementioned adjustment mechanism enables the same set of cutting components 3 to adapt to various different cutting needs, increasing the versatility of the glass cutter, reducing the need to change cutting equipment for different cutting tasks, and improving the efficiency of equipment use.
[0054] One end of the cutting shaft 32 extends out of the protective cover 31. The bidirectional screw 5 has an installation cavity 51 and a sliding cavity 52. The installation cavity 51 and the sliding cavity 52 are connected. A slider 53 is slidably connected in the sliding cavity 52. A connecting post 54 is connected to the front of the slider 53. A spring 55 is connected to the back of the slider 53. An operating block 56 is connected to the other end of the connecting post 54. The operating block 56 is in contact with one end of the cutting assembly 3. Damping textures are provided on the contact surfaces of the cutting shaft 32 and the operating block 56.
[0055] The control block 56 has a groove, and the control block 56 is interference-fitted to one end of the cutting shaft 32. The control block 56 is a regular hexagonal protrusion, and the outer side of the control block 56 is provided with anti-slip texture.
[0056] In the initial state, the spring 55 is in a natural or pre-compressed state, the slider 53 is located in the sliding cavity 52, one end of the connecting post 54 is connected to the slider 53, and the other end is connected to the operating block 56.
[0057] The control block 56 is attached to one end of the cutting shaft 32, and the damping textures on the contact surfaces of the two interact to provide a certain frictional force, so that the control block 56 remains relatively stationary when it is not subjected to external force.
[0058] When it is necessary to adjust the gap between the auxiliary blades 41, a rotational force is applied to the control block 56.
[0059] Because the control block 56 is a regular hexagonal protrusion and has anti-slip texture on the outside, it is convenient for the operator to grip and apply force.
[0060] The control block 56 is interference-fitted with the cutting shaft 32. When the control block 56 rotates, it drives the cutting shaft 32 to rotate as well.
[0061] The rotation of the cutting shaft 32 causes the bidirectional screw 5 to rotate, thereby enabling the two auxiliary blades 41 to move towards or away from each other within the connection port 33, thus adjusting the blade gap.
[0062] During the adjustment process, if a large resistance is encountered, the slider 53 will slide within the sliding cavity 52, compressing the spring 55.
[0063] Spring 55 acts as a buffer to prevent the adjustment operation from jamming or damaging parts due to excessive instantaneous resistance.
[0064] When the resistance disappears, the spring 55 returns to its original shape, pushing the slider 53 back to its original position, so that the operating block 56 and the cutting shaft 32 always remain in contact, ensuring the continuity of the adjustment operation.
[0065] The cooperation between spring 55 and slider 53 provides buffer protection for the adjustment process. When encountering unexpected resistance, it can avoid damage to the bidirectional screw 5, cutting shaft 32 or other related components caused by hard resistance, thus extending the service life of the equipment and reducing maintenance costs and downtime.
[0066] The interference fit between the control block 56 and the cutting shaft 32, as well as the damping texture on the mating surface, ensures that the control block 56 can stably drive the cutting shaft 32 to rotate during normal adjustment without slippage, thus ensuring the accuracy and reliability of blade gap adjustment.
[0067] The hexagonal bump design and the anti-slip texture on the outside greatly improve the convenience and stability of the operator applying force to the control block 56, making the adjustment operation easier and more precise, reducing the difficulty of operation and improving work efficiency.
