Description

Technical Field

[0001] The utility model relates to the technical field of cutting equipment, in particular to a glass tube cutting device. Background Art

[0002] As the glass industry continues to develop, the tools that go with it are also constantly innovating. When manufacturing smaller glass tube segments, the industry usually cuts a longer glass tube into the required glass tubes according to size. However, due to the fragility of the glass tube wall, when cutting, it is necessary to manually scratch the inner wall of the glass tube before it can be cut slowly. This working mode not only has low production efficiency, but also is very easy to cause the glass tube to break due to operator errors. In addition, since the cutting tool for cutting the glass tube is made of rigid material, even if the glass tube is finally cut, it will cause burrs or damage to the edges of the glass tube.

[0003] In order to solve the above problems, the Chinese utility model patent "A thermal explosion glass tube cutting device" with application number 201420855760.6 records a device, including a frame, rollers, a motor, a cutting part and a high-temperature flame head; two rollers are provided on the frame, and a sprocket is provided at one end of the roller, which forms a transmission connection with the motor fixed on the frame; the cutting part is located in the middle and upper part of the other end of the two rollers, and it is connected to the frame; the high-temperature flame head is arranged in parallel at the lower end of the cutting part.

[0004] The equipment has the following problems: First, the cutting knife is operated by hand, and according to the instructions and drawings, the length of the section of the hand-held rod close to the cutting knife is greater than the length of the hand-held end. According to the principle of lever, the force and displacement amplitude applied by the worker at the hand-held end will be multiplied at the cutting knife end, which leads to difficult operation, large errors and uneven product quality.

[0005] At the same time, according to the description and the drawings, the cutting knife end is a free end, which means that when loading the material, it is necessary to manually hold the handle to keep it horizontal. Only in this case can the glass tube be placed in the working position, and the operating efficiency is greatly reduced.

[0006] Thirdly, in actual use, the equipment requires simultaneous control of two parts: on the one hand, the hand-held lever of the cutting knife needs to be operated, and on the other hand, the control lever of the high-temperature flame head needs to be operated at the same time. A worker needs to operate two different structures at the same time. Glass tube cutting is a precise job, so this multitasking work method puts higher demands on workers, and will also affect work efficiency and reduce product quality. Utility Model Content
