[0021] It should be understood that the embodiments of the present invention shown in the exemplary embodiments are illustrative only. Although only a few embodiments are described in detail in the present invention, it is easy for those skilled in the art to understand that multiple modifications are feasible without actually departing from the teachings of the subject matter of the present invention. Accordingly, all such modifications should be included within the scope of the present invention. Without departing from the gist of the present invention, other replacements, modifications, changes and deletions may be made to the design, operating conditions and parameters of the following exemplary embodiments.
[0022] As mentioned in the background technology above, the inventors realize that the existing glass tube cutting device has at least the problem of low efficiency in cutting glass tubes. Based on these problems and room for improvement in the prior art, the inventors provide a cutting device with adjustable speed in one or more embodiments, which is believed to solve one or more problems in the prior art including the aforementioned problems.
[0023] The utility model provides a cutting device with adjustable speed, comprising: a support 15, a mounting seat 14 and a cutting wheel 6. The support 15 is arranged beside the glass tube production line 12. The mounting seat 14 is arranged on the support 15 and connected to the support 15 through a position adjustment device so that the position of the mounting seat 14 relative to the support 15 can be adjusted to adapt to glass tube production lines 12 of different specifications. The cutting wheel 6 is rotatably arranged on the mounting seat 14, and the cutting wheel 6 cuts the glass tube 11 when rotating. The speed of the cutting wheel 6 is adjustable according to the diameter of the glass tube 11. Specifically, the speed of the cutting wheel 6 of the present application is inversely proportional to the diameter of the glass tube 11. The calculation formula is: n = 1000v / πD, where v represents the cutting speed, in m / min, which is determined by the durability of the tool; n represents the speed of the cutting wheel 6, in r / min; and D represents the diameter of the glass tube 11, in mm. This means that if the diameter of the glass tube 11 increases, in order to maintain the same cutting speed, the speed of the cutting wheel 6 needs to be reduced. On the contrary, if the diameter of the glass tube 11 is reduced, in order to achieve the same cutting effect and efficiency, the rotation speed of the cutting wheel 6 needs to be increased.
[0024] Compared with the prior art, the utility model provides a mounting seat 14 with adjustable position, so that when cutting the glass tube 11, there is no need to manually control the position of the glass tube 11, and the glass tube 11 can be cut in batches, eliminating the influence of artificial subjective factors, reducing the operation steps, improving work efficiency, and being adaptable to different glass tube production lines 12. The rotation speed of the cutting wheel 6 is adjustable according to the diameter of the glass tube 11, which can avoid uneven cuts, cut cracks, etc. when cutting glass tubes 11 of different diameters, and can improve the quality of the rounded mouth of the molding, with a high yield rate.
[0025] In some embodiments, the cutting device with adjustable speed further comprises a pressing sheet 5, which is mounted on the mounting seat 14 and is located above the cutting wheel 6 in the vertical direction. Specifically, along the moving direction of the glass tube 11, the pressing sheet 5 is located at the rear side of the cutting wheel 6. After the glass tube 11 is cut by the cutting wheel 6, the pressing sheet 5 presses down the glass tube head outside the cutting line to ensure that the glass tube head is separated from the glass tube body, thereby avoiding the situation where the glass tube 11 cannot be cut. Figure 2 As shown, the glass tube 11 moves from left to right under the action of the glass tube production line 12, and the glass tube 11 can rotate. The cutting wheel 6 is located below the glass tube 11. The cutting wheel 6 rotates to cut the glass tube 11 around the circle. Most of the glass tube heads will fall directly after cutting, but a small part of the cut glass tube heads may still remain on the glass tube body. The pressing sheet 5 is located at the upper right of the cutting wheel 6. After the cut glass tube 11 moves to the right to the position where the pressing sheet 5 contacts, the glass tube head is separated from the glass tube body under the top pressure of the pressing sheet 5, thereby ensuring that each glass tube 11 can be cut.
[0026] In some embodiments, the lower surface of the pressing piece 5 is a horizontal plane, and the pressing piece 5 is mounted on the mounting seat 14 through a height adjustment mechanism, so that the height of the pressing piece 5 relative to the cutting wheel 6 is adjustable. Specifically, the height adjustment mechanism includes a connecting plate 16 and a threaded rod, and the connecting plate 16 is provided with a threaded hole, and the threaded rod is connected to the pressing piece 5. The pressing piece 5 is threadedly connected to the threaded hole on the connecting plate 16 through the threaded rod, and its height is adjusted by rotating the pressing piece 5. Since the sizes of glass tubes 11 produced in different batches may be different, in order to achieve a downward pressing effect on the head of the glass tube, the pressing piece 5 can also be adjusted separately after the position of the cutting wheel 6 is determined, so that the distance from the pressing piece 5 to the axis of the glass tube 11 in the vertical direction is greater than the outer radius of the glass tube 11, and less than the outer diameter of the glass tube 11, so as to avoid the problem of incompatibility with the glass tube 11.
[0027] In some embodiments, the speed-adjustable cutting device further comprises a driving motor 3, the output end of the driving motor 3 is connected to a transmission shaft 13, the transmission shaft 13 is rotatably mounted on a mounting seat 14, the cutting wheel 6 is mounted on the transmission shaft 13, the driving motor 3 controls the rotation of the cutting wheel 6 through the transmission shaft 13, and the speed of the cutting wheel 6 is controlled by the driving motor 3. The mounting seat 14 is a bearing mounting seat, and the driving motor 3 is a micro motor with a light weight, so only one bearing mounting seat is used to provide support for the driving motor 3, the transmission shaft 13, the cutting wheel 6 and the pressing sheet 5, and the structure is simple and reliable. The driving motor 3 is provided with a frequency converter 4 for controlling the speed of the driving motor 3. Through the setting of the frequency converter 4, the speed of the driving motor 3 can be automatically adjusted, and the adjustment accuracy is high.
[0028] In some embodiments, the cutting device with adjustable speed further includes a sensor, which is disposed on the mounting base 14 or on the glass tube production line 12, and is used to detect the diameter of the glass tube 11 and transmit the detected signal to the frequency converter 4. The frequency converter 4 can automatically control the speed of the driving motor 3 according to the diameter of the glass tube 11, with a high degree of intelligence, and reduces the tedious steps of manual calculation.

By providing a first adjusting component that moves up and down, precise positioning of the mounting seat 14 in the up and down directions can be achieved, thereby improving the cutting accuracy.
[0030] In some embodiments, the first movable plate 8 includes a vertical plate and a horizontal plate connected to the lower end of the vertical plate, the first threaded hole is set on the horizontal plate, and a vertical slide is set on the support 15. The vertical plate slides in the up and down directions and passes through the vertical slide. The vertical slide is also provided with a first locking bolt for locking the vertical plate to limit the position of the first movable plate 8 after the position of the first movable plate 8 is determined to prevent the first movable plate 8 from slipping.
[0031] In some embodiments, the position adjustment device further includes a second adjustment component, which includes a second fixed plate 9, a second movable plate 10 and a second adjustment knob 2; the second fixed plate 9 is horizontally mounted on the top of the first movable plate 8, and a second limiting hole is provided on the vertical side of the second fixed plate 9; the second movable plate 10 is slidably mounted on the second fixed plate 9 along the direction of the axis of the glass tube 11, and a second threaded hole is provided on the second movable plate 10, and the second adjustment knob 2 is horizontally arranged, one end of the second adjustment knob 2 is rotatably inserted into the second limiting hole, and the other end of the second adjustment knob 2 is screw-driven with the second threaded hole, and the mounting seat 14 is mounted on the second movable plate 10. The second adjustment knob 2 includes a second screw and a second knob connected to the top of the second screw, and the rotation of the second screw is controlled by controlling the rotation of the second knob. When the second screw rotates, the second movable plate 10 moves in the horizontal direction relative to the second fixed plate 9, thereby adjusting the horizontal cutting position of the cutting wheel 6 and the pressing sheet 5 relative to the glass tube 11. By providing a second adjustment component that is transmission-connected to the first adjustment component, the vertical and horizontal positions of the mounting base 14 can be adjusted together to adapt to glass tubes 11 of different sizes and specifications to meet different cutting requirements.
[0032] In some embodiments, the second movable plate 10 includes a horizontal plate that slides horizontally above the second fixed plate 9, and a vertical plate connected to the horizontal plate. The second threaded hole is arranged on the vertical plate. A horizontal slide is arranged on the second fixed plate 9. The horizontal plate slides in a horizontal direction through the horizontal slide.

[0033] like Figure 2 As shown, the working principle and working process of a cutting device with adjustable speed provided by an embodiment of the utility model are as follows:
[0034] First, the height and horizontal position of the mounting seat 14 are adjusted by the first adjustment component and the second adjustment component respectively, so that the cutting wheel 6 is located below the glass tube 11 and in contact with the glass tube 11. If necessary, the height of the pressing plate 5 relative to the glass tube 11 is also adjusted separately. The glass tube production line 12 drives the glass tube 11 thereon to rotate and move from left to right.

The frequency converter 4 adjusts the speed of the driving motor 3 according to the set parameters, so that the speed of the cutting wheel 6 is adapted to the diameter of the glass tube 11. When the glass tube 11 moves to the position where the cutting wheel 6 is located, the cutting wheel 6 cuts the end of the glass tube 11 at this position so that the length of the glass tube 11 meets the requirements. After the cut glass tube 11 moves to the right to the position of the pressing plate 5, the glass tube head is separated from the glass tube body under the top pressure of the pressing plate 5, so as to ensure that each glass tube 11 can be cut.
