Description

Technical Field

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

[0002] A glass cutting machine is a type of processing machinery specifically designed for glass processing. It typically places glass sheets on a cutting table for cutting. Glass has a wide range of applications in industrial production and daily life, and it usually needs to be cut and processed before being used in various products.

[0003] Existing glass cutting equipment places the glass on a processing table, starts a motor to drive the track to rotate, and the track drives the cutting blade to cut the glass. The processing table limits the glass, but the glass is often of the same thickness when it is limited, which restricts the glass cutting.

[0004] However, when cutting glass of different thicknesses, existing glass limiting devices, such as limiting plates, are not easy to adjust in height, making it difficult to effectively limit glass plates of different thicknesses and thus difficult to cut them effectively. Traditional cutting blades are also difficult to adjust in height, making it impossible to make effective contact with glass surfaces of different thicknesses, thus making it difficult to cut them effectively. Furthermore, since glass itself is relatively brittle, it is easily damaged during limiting, increasing losses. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] It solves the problem of inconvenience in cutting glass of different thicknesses, improves work efficiency, enhances glass protection, and reduces losses.

[0007] (II) Technical Solution

[0008] In view of the above-mentioned problem of inconvenience in cutting glass of different thicknesses, this utility model is proposed.

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a glass cutting device for cutting glass of different thicknesses, comprising a machine body, a motor fixedly installed at the rear end of the machine body, a cutting cavity opened on the front of the machine body, and a slot opened at the top of the upper cavity of the cutting cavity, a main shaft fixedly connected to the output end of the motor, a rotating block threadedly connected to the outer wall of the main shaft, a connecting rod fixedly connected to the outer wall of the rotating block, the outer wall of the connecting rod being movably connected to the inner wall of the slot, a cutting blade elastically installed at the bottom of the connecting rod, and a plurality of glass squeezing and fixing limiting plates being slidably installed at the bottom of the cutting cavity, and rubber pads being fixedly connected to the top of the inner wall of each limiting plate.

[0010] As a preferred embodiment of the glass cutting device of the present invention for facilitating the cutting of glass of different thicknesses, wherein: a rectangular groove is provided at the end of the connecting rod away from the rotating block, a first spring is fixedly connected to the top of the inner wall of the rectangular groove, and the bottom end of the first spring is fixedly connected to the top of the cutting blade.

[0011] As a preferred embodiment of the glass cutting device of the present invention for facilitating the cutting of glass of different thicknesses, the lower cavity of the cutting chamber is provided with four limiting grooves arranged in a rectangular array, and the inner wall of the limiting groove is slidably inserted into the limiting plate.

[0012] As a preferred embodiment of the glass cutting device of the present invention, which facilitates cutting glass of different thicknesses, a second spring is installed between the limiting plate and the corresponding limiting groove.

[0013] As a preferred embodiment of the glass cutting device for cutting glass of different thicknesses described in this utility model, the bottom end of the limiting plate is provided with a threaded groove, the inner wall of the threaded groove is threaded with a threaded rod, and the bottom end of the threaded rod is fixedly connected with a first gear.

[0014] As a preferred embodiment of the glass cutting device for cutting glass of different thicknesses described in this utility model, wherein: the outer wall of the first gear meshes with a second gear, the two ends of the machine body are provided with through holes communicating with the corresponding two limiting grooves, and a rotating rod that slides through the through hole is fixedly inserted into the two second gears, and one end of the rotating rod extends out of the machine body and is fixedly connected to a handle.

[0015] The beneficial effects of this utility model are:

[0016] 1. By using the handle to drive the second gear to synchronously adjust the height of multiple limiting plates, glass of different thicknesses can be fixed. Due to the above-mentioned lifting and adjusting method, the action is gentle and linearly controllable, so that the glass is not easily squeezed and damaged when it is limited and fixed.

[0017] 2. By installing rubber pads at the contact points with the glass, rigid collisions are avoided when the glass is limited and fixed, making it less likely to be squeezed and damaged when the glass is limited and fixed. At the same time, the sliding friction resistance generated by the contact between the rubber pads and the glass prevents the glass from slipping during cutting, thus improving the safety of glass cutting.

[0018] 3. Furthermore, since the cutting blade and the connecting rod are elastically installed, the cutting blade can adaptively fit onto glass surfaces of different thicknesses when the connecting rod moves linearly back and forth, thus completing the effective cutting of glass of different thicknesses.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1 and Figure 2This is the first embodiment of the present invention, providing a glass cutting device for easily cutting glass of different thicknesses. It includes a body 1, with a motor 2 fixedly mounted at the rear end of the body 1. A slot 9 is formed at the top of the inner wall of the body 1, allowing a connecting rod 3 to move horizontally. One end of the motor 2 is fixedly connected to a spindle 6, and a bearing is fixedly connected to one end of the outer wall of the spindle 6 to reduce the friction coefficient between the spindle 6 and the bearing seat, ensuring the rotational accuracy of the spindle 6 and reducing energy consumption. The outer wall of the spindle 6 is threaded, and the thread on the spindle 6 is threadedly connected to a rotating block 8. The rotating block 8 is threadedly connected to the outer wall of the spindle 6, and the inner wall of the rotating block 8 is... The rotating block 8 is connected to the main shaft 6 by a thread, which allows the rotating block 8 to drive the connecting rod 3 to perform a translational cutting motion. The connecting rod 3 is fixedly connected to the outer wall of the rotating block 8. One end of the connecting rod 3 is clamped with a cutting blade 4. A rectangular groove 13 is opened at the end of the connecting rod 3 away from the rotating block 8. A first spring 7 is fixedly connected to the top of the inner wall of the rectangular groove 13. The bottom end of the first spring 7 is fixedly connected to the top end of the cutting blade 4, which allows the cutting blade 4 to be used with glass of different thicknesses. The top end of the cutting blade 4 and the bottom end of the rectangular groove 13 limit each other, so that the cutting blade 4 can be used with glass of different thicknesses. The outer wall of the connecting rod 3 is movably connected to the inner wall of the groove 9.

[0028] During use, motor 2 is started, and the forward rotation of motor 2 drives the main shaft 6 to rotate. Since the rotating block 8 is threadedly connected to the main shaft 6, there is sliding friction resistance between the two. Therefore, the rotation of the main shaft 6 should have driven the rotating block 8 to rotate synchronously. However, since the connecting rod 3 installed at the bottom of the rotating block 8 is slidably installed in the slot 9, the connecting rod 3 cannot rotate synchronously, which in turn causes the rotating block 8 to also not rotate synchronously. It can only move linearly along the axis of the main shaft 6. Finally, the connecting rod 3 drives the cutting blade 4 to move synchronously to cut the glass. Since the cutting blade 4 and the connecting rod 3 are elastically installed, the cutting blade 4 can adaptively fit the glass surface of different thicknesses, thus facilitating the effective cutting of glass of different thicknesses.

[0029] Example 2

[0030] Reference Figure 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: four limiting grooves 12 are provided at the bottom of the inner wall of the body 1, and the four limiting grooves 12 are evenly distributed and symmetrically distributed at the bottom of the inner wall of the body 1. The limiting grooves 12 are used to install the limiting plate 5. The limiting plate 5 is used to limit the four corners of the glass so that it is not easy to fall off. A rubber pad 10 is fixedly connected to the top of the inner wall of the limiting plate 5 to reduce the risk of slipping when placing the glass. A second spring 19 is fixedly connected to the bottom of the limiting plate 5. The second spring 19 is used to reduce the pressure of the limiting plate 5 and make it easier for the limiting plate 5 to reset. One end of the second spring 19 is fixedly connected to the bottom of the limiting groove 12.

[0031] A threaded groove 18 is provided on one side of the bottom end of the limiting plate 5. The inner wall of the threaded groove 18 is threaded. A threaded rod 17 is threadedly connected to the inner wall of the threaded groove 18, so that when the threaded rod 17 rotates, it drives the limiting plate 5 to limit the glass. A first gear 16 is fixedly connected to one end of the outer wall of the threaded rod 17.

[0032] The outer wall of the first gear 16 meshes with the second gear 14. The inner wall of the second gear 14 is fixedly connected to a rotating rod 11. When the rotating rod 11 rotates, it will drive the second gear 14 and the threaded rod 17. Two through holes are opened at one end of the machine body 1. The outer wall of the rotating rod 11 is movably connected to the inner wall of the through holes. A handle 15 is fixedly connected to one end of the rotating rod 11. The handle 15 controls the rotating rod 11.

[0033] During use, first pull the cutting blade 4 upwards, at which point the first spring 7 is forced to compress, placing the glass on the bottom of the inner wall of the cutting cavity. Then, slowly release the cutting blade 4. The kinetic energy provided by the elastic recovery of the first spring 7 pushes the cutting blade 4 downwards and presses it against the upper surface of the glass. Turn the handle 15, which drives the rotating rod 11 to rotate. The rotating rod 11 drives the second gear 14 to rotate, which in turn drives the first gear 16 to rotate. The first gear 16 drives the threaded rod 17 to rotate, and simultaneously the threads on the threaded rod 17 and the internal threads of the threaded groove 18... The glass is then connected by a groove, causing the limiting plate 5 to move along the limiting groove 12. The second spring 19 is compressed, and the inner wall of the limiting plate 5 limits the glass. The motor 2 is started, and the motor 2 drives the main shaft 6 to rotate. The main shaft 6 drives the connecting rod 3 to move along the slot 9. The connecting rod 3 drives the cutting blade 4 to move and cut. After cutting, the handle 15 is rotated in the opposite direction. The handle 15 drives the rotating rod 11 to rotate. The rotating rod 11 drives the limiting plate 5 to move along the limiting groove 12 through the second gear 14 and the first gear 16. The second spring 19 is released, and the cut glass is taken out. The operation is now complete.

[0034] The remaining structure is the same as that in Example 1.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
