They can be used in various fields such as electric light sources, semiconductors, optical communications, military industry, metallurgy, building materials, chemistry, machinery, electricity, and environmental protection. In the existing glass tube processing process, it is usually necessary to cut the longer glass tubes into a certain length according to specified requirements.

[0003] For example, the Chinese patent with publication number CN220389902U proposes a round-mouth cutting machine for medicinal glass tubes, including a pedestal, a support panel on the top of the pedestal, a feeding mechanism and a cutting mechanism arranged in sequence along the Y direction on the support panel, the feeding mechanism comprising an upper rotating rod, a lower rotating rod, a vertical arm, a first telescopic cylinder, a conveyor belt and a driving mechanism, two through holes are arranged on the support panel, a lower rotating rod is arranged in each of the two through holes, the lower rotating rod extends along the X direction, the conveyor belt is sleeved on the two lower rotating rods, two vertical arms are installed on the support panel, a slider is connected to the vertical arm in a longitudinal sliding manner, an upper rotating rod is rotatably connected between the two sliders, the upper rotating rod is arranged above the conveyor belt, the first telescopic cylinder is used to drive the slider to rise and fall, and the driving mechanism is used to drive one of the lower rotating rods to rotate. The utility model can stably transport glass tubes and avoid scratches on the glass tubes.

[0004] In the above scheme, the device uses a conveyor belt to transport the glass tube and a saw blade cutter to cut the glass tube. There are the following disadvantages: the length of each cut needs to be measured before it can be carried out, the cutting error caused by the measurement is more likely to occur, and the work efficiency is low when it is necessary to cut glass tubes of uniform specifications. Utility Model Content

[0005] The utility model aims to provide a length positioning mechanism for a glass tube cutting machine to solve the problems that the length of each cut needs to be measured before it can be carried out, the cutting error caused by the measurement is likely to occur, and the working efficiency is low when glass tubes of uniform specifications need to be cut.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a length positioning mechanism of a glass tube cutting machine, comprising a workbench, a side panel is fixedly installed on the top surface of the workbench, a conveyor belt is arranged inside the workbench, a telescopic cutting knife is fixedly installed on one side of the side panel, a mounting plate is fixedly installed on one side of the workbench, a sliding rail is fixedly installed on the top surface of the mounting plate, a sliding block is slidably inserted into the outer wall of the sliding rail, a scale is fixedly installed on one side of the mounting plate, and a touch sensor module is fixedly installed on one side of the sliding block.

[0007] Preferably, the internal thread of the sliding block is connected with a bolt.

[0008] Preferably, an indicating pointer is fixedly mounted on one side of the sliding block.

[0009] Preferably, a brake motor is fixedly mounted inside the mounting plate, and a rotating plate is fixedly mounted on one end of the telescopic shaft of the brake motor.

[0010] Preferably, an electric push rod is fixedly mounted on one side of the side plate, and one end of the telescopic shaft of the electric push rod passes through the interior of the side plate and is fixedly mounted with a clamping plate.

[0011] Preferably, a plurality of rotating shafts are fixedly installed inside the clamping plate, a rotating roller is rotatably clamped on the outer wall of the rotating shaft, and a sponge ring is fixedly installed on the outer wall of the rotating roller.

[0012] Compared with the prior art, the length positioning mechanism of a glass tube cutting machine using the above technical solution has the following beneficial effects:

[0013] 1. When in use, the cutting position of the entire glass tube to be cut can be limited each time, so that the length of the cut glass tube is the same, reducing the possibility of cutting errors each time, improving cutting accuracy, effectively reducing the time required for the distance measurement process, and effectively improving the working efficiency of glass tube cutting;

[0014] Second, through the bolt, when the position of the sliding block is determined, the bolt is rotated so that one end of the bolt squeezes the sliding rail, thereby limiting the position of the sliding block. Through the indicating pointer, the position of the sliding block can be adjusted more easily to improve work efficiency. Through the brake motor, when the glass tube is cut, the cut glass tube will stay on the surface of the rotating plate. At this time, the brake motor is started to drive the rotating plate to rotate, so that the glass tube rolls away from the top of the rotating plate, which is convenient for collecting the cut glass tube;

[0015] 3. Through the electric push rod, when the electric push rod is started, it pushes the clamping plate to move, squeezes and clamps the glass tube placed above the conveyor belt, and improves the cutting stability. Through the rotating roller, when the conveyor belt transports the glass tube clamped by the clamping plate, the rotating roller rotates, which can effectively reduce the friction between the glass tube and the clamping plate and improve the smoothness of transportation. Through the sponge ring, the softness of the rotating roller surface is improved to avoid scratching with the glass tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] During use, the staff can place the glass tube above the conveyor belt 3 and transport the glass tube through the conveyor belt 3. At the same time, before work, the position between the touch sensor module 9 and the cutting position of the telescopic cutting knife 4 can be adjusted by sliding the sliding block 7, and the distance can be observed by observing the scale above the scale 8. When the glass tube is transported by the conveyor belt 3 to contact the surface of the touch sensor module 9, the touch sensor module 9 converts the information into an electrical signal and transmits it to the PLC controller, which then controls the conveyor belt 3 to pause. At this time, the telescopic cutting knife 4 starts to cut the glass tube, so that the cutting position of the entire glass tube to be cut can be limited each time, so that the length of the cut glass tube is the same, the possibility of each cutting error is reduced, the cutting accuracy is improved, the time required for the distance measurement process is effectively reduced, and the work efficiency of glass tube cutting is effectively improved.

[0025] During use, through the bolt 10, when the position of the sliding block 7 is determined, the bolt 10 is rotated so that one end of the bolt 10 squeezes the sliding rail 6, thereby limiting the position of the sliding block 7. Through the indicating pointer 11, the position of the sliding block 7 can be adjusted more easily to improve work efficiency. Through the brake motor 12, when the glass tube is cut, the cut glass tube will stay on the surface of the rotating plate 13. At this time, the brake motor 12 is started to drive the rotating plate 13 to rotate, so that the glass tube rolls away from the top of the rotating plate 13, which is convenient for collecting the cut glass tube.

The rotating roller 17, when the conveyor belt 3 transports the glass tube clamped by the clamping plate 15, rotates, which can effectively reduce the friction between the glass tube and the clamping plate 15 and improve the transportation smoothness. The sponge ring 18 is used to increase the softness of the surface of the rotating roller 17 to avoid scratching the glass tube.
