As shown in fig. 1, a glass tube cutting apparatus of a first embodiment includes: a glass tube pulling assembly 10, a glass tube cutting assembly 20, and a temperature sensing assembly 30. The glass tube traction assembly 10 comprises a runway structure 11, a temperature adjusting structure 12 and a traction structure 13, wherein the temperature adjusting structure 12 and the traction structure 13 are arranged on the runway structure 11; a glass tube cutting assembly 20, the glass tube cutting assembly 20 being disposed on a side of the traction structure 13 remote from the temperature adjustment structure 12; temperature sensing assembly 30 the temperature sensing assembly 30 is provided on the runway structure 11.

By applying the technical solution of the first embodiment, the glass tube is driven by the traction structure 13 to move along the runway structure 11, and the runway structure 11 can fix the moving path of the glass tube. The temperature adjusting structure 12 is provided on the runway structure 11 to adjust the temperature of the glass tube within a predetermined temperature interval. The glass tube cutting assembly 20 is disposed on a side of the pulling structure 13 remote from the temperature adjusting structure 12, and is capable of cutting a glass tube. The temperature detecting unit 30 is provided on the runway structure 11 to detect the temperature of the glass tube (the temperature around the glass tube may be detected, the temperature of the glass tube may be indirectly known, or the temperature of the glass tube may be directly detected). The technical scheme of the embodiment can effectively solve the problem that the cutting quality of the glass tube is affected by large temperature change in the prior art.

The runway structure 11 is understood to be a conveying structure that serves as an uninterrupted transport of the glass tube during the tube drawing and cutting phase. For this field, the conveying structure of the glass tube is generally named runway structure 11.

As shown in fig. 1, in the embodiment of the first embodiment, the temperature detecting assembly 30 is provided on the input side of the traction structure 13. The traction structure 13 plays a role in traction on the glass tube to drive the glass tube to axially move along the runway structure 11, and the rotation inside the traction structure 13 is changed into the translation of the glass tube. Meanwhile, the temperature detection assembly 30 is arranged at the input end of the traction structure 13, so that the temperature detection assembly has the advantages of small movement amount and small vibration amount, and the accuracy of the temperature detection assembly 30 is improved.

As shown in fig. 1 and 2, in the embodiment of the first embodiment, the glass tube cutting apparatus further includes a control assembly 40, the temperature detecting assembly 30 includes an infrared temperature sensor 31, and the infrared temperature sensor 31 and the temperature adjusting structure 12 are electrically connected to the control assembly 40. The infrared temperature sensor 31 is electrically connected to the control assembly 40 and transmits a 4-20mA signal to the control assembly 40 upon detecting that the temperature of the glass tube is not within an effective temperature interval (predetermined temperature interval). The control assembly 40 receives the 4-20mA signal from the infrared temperature sensor 31 to control the temperature adjustment structure 12, which is electrically connected to the control assembly 40, to begin operation. The control component 40 is electrically connected with the infrared temperature sensor 31 so as to receive 4-20mA signals rapidly, the control component 40 is electrically connected with the temperature regulating structure 12 so that the control component 40 can react rapidly to the control of the temperature regulating structure 12, the control component 40 can timely react to the 4-20mA signals exceeding the effective temperature interval and control the temperature regulating structure 12 to regulate and control the temperature, the control effect is enhanced, and the influence of temperature change on the cutting quality of the glass tube is effectively reduced.

The infrared temperature sensor 31 does not need to be contacted during detection, and has the advantages of dexterity, convenience and stable temperature signal. If the temperature of the glass tube is within an effective temperature range in the tube drawing cutting process, cutting burrs during tube drawing cutting can be reduced, quality loss is reduced in subsequent procedures, and product quality is improved. If the temperature is not within the effective temperature range, the subsequent step of scratching-proof spraying coating of the glass tube is invalid, so that the quality problem of the finished product of the cut glass tube is caused.

When the temperature is higher than the set value, the operating frequency of the fan 121 is increased, the wind power is increased, the temperature reduction effect is realized, when the temperature detection assembly 30 detects that the temperature falls back into the normal effective temperature range, the signal 4-20mA is transmitted to the control assembly 40, and the control assembly 40 controls the fan 121 to stop operating and not to adjust. When the temperature is lower than the set value, the operating frequency of the fan 121 is reduced, and the wind power is reduced, so that the influence of the fan 121 on the temperature of the glass tube is reduced.

The effective temperature zone is set to prevent frequent adjustment, and the effective temperature zone is set to be a dead zone, and may not participate in adjustment. Once the temperature exceeds the dead zone range, the fan 121 frequency begins to be adjusted, enabling effective control of the cutting temperature.

As shown in fig. 1, in the embodiment of the first embodiment, the distance between the fan 121 and the traction structure 13 is between 2.5 meters and 4.5 meters. The most suitable temperature is detected here, and the glass tube is suitable at this temperature, and is suitable at the time of later cutting, and the temperature fluctuation is not large.

The frequency converter adjusts the output frequency of the fan 121 motor according to the received temperature signal, so that the cutting temperature is effectively controlled. Meanwhile, the frequency converter controls the operation frequency of the fan 121, so that the operation efficiency of the fan 121 can be improved, and the frequency converter controls the fan 121 to adjust the rotation speed of the fan 121 according to actual needs, so that the effects of saving energy and reducing consumption are achieved, meanwhile, the failure rate of equipment of the fan 121 is reduced, and the service life of the equipment is prolonged.

The driving structure 23 is fixed on the base 24, and the output end of the driving structure 23 is connected with the spray gun base 21, so that the power of the driving structure 23 can be stably and rapidly transmitted to the spray gun base 21. The torch base 21 is movably mounted on the base 24 for flame heating the glass tube.
