Technical Field
[0001] The utility model relates to the technical field of motor protection, in particular to a tube drawing and forming machine with an input shaft baffle structure. Background Art
[0002] The tube drawing machine is a key equipment for forming glass liquid into glass tubes. During operation, high-temperature glass liquid enters the material bin of the tube drawing machine. Driven by the motor, the extrusion head of the tube drawing machine can rotate, extruding and cooling the molten glass at the same time, thereby obtaining continuously formed glass tubes.
[0003] The motor is very susceptible to the influence of the tube drawing machine. In order to overcome the high temperature transmitted to the motor, the output shaft of the motor, that is, the input shaft of the tube drawing machine is generally set longer. However, the increase in the length of the power shaft will lead to an increase in the power output of the motor, which requires the replacement of a high-power motor and increases energy consumption. There is an urgent need for a tube drawing machine with an input shaft baffle structure that does not require an increase in the shaft length and can cool the shaft body. Utility Model Content

[0025] Example 1:
[0026] This embodiment Figure 1 As shown, a tube drawing and forming machine with an input shaft baffle structure includes a tube drawing and forming machine 1 and a motor 2. The output shaft 3 of the motor 2 passes through the insulation wall of the tube drawing and forming machine 1 and is used to drive the extrusion head of the forming machine 1. A baffle structure 4 is provided on the output shaft 3. The baffle structure 4 includes a baffle 5, a spiral spring piece 6 and an annular tube 7. Two baffles 5, a spiral spring piece 6 and an annular tube 7 are all sleeved on the output shaft 3, and the two baffles 5 are respectively connected to the outer wall of the tube drawing and forming machine 1 and the outer shell of the motor 2. The two ends of the spiral spring piece 6 are respectively pressed against the two baffles 5, and the two ends of the annular tube 7 are respectively connected to the two baffles 5, and the inner wall of the annular tube 7 is slidably matched with the outer peripheral surface of the spiral spring piece 6. A spiral cavity 9 is formed between the output shaft 3, the baffle 5, the annular tube 7 and the spiral spring piece 6. The two annular tubes 7 are respectively provided with a first interface 10 and a second interface 11 connected to the spiral cavity 9. The first interface 10 and the second interface 11 are respectively connected to the discharge port and the return port of the external cold source.
[0027] A baffle structure 4 is installed on the output shaft 3 of the motor 2, that is, the input shaft of the tube drawing and forming machine 1. The cooling medium provided by the external cold source enters the spiral cavity 9 through the first interface 10, moves along the spiral cavity 9, cools the output shaft 3, takes away heat for cooling, and then returns to the return port of the external cold source through the second interface 11. During this period, the heated cooling medium can be cooled down by a compressor or other heat exchange equipment for reuse. The baffle structure 4 seals the output shaft 3 between the tube drawing and forming machine and the motor in the form of a set, and forms a spiral cavity that can cool the power shaft. With the cooperation of the external cold source, the cooling medium cools the power shaft through the spiral cavity, blocking the tube drawing and forming machine from transmitting high temperature to the motor through the power shaft, thereby ensuring the normal operation and service life of the motor.
[0028] Example 2:
[0029] Based on the above examples, this embodiment Figure 2 As shown, a rubber tube 8 is provided in the middle of the ring tube 7 , and the rubber tube 8 is tightly attached to the outer peripheral surface of the spiral spring piece 6 .
[0030] The rubber tube 8 has certain contraction and expansion properties. When the motor 2 is working, it will vibrate and the spiral spring 6 may stretch or contract. It is also possible that the cooling medium is supplied too much. At this time, the rubber tube 8 can change accordingly to ensure the safe operation of the baffle structure 4.
[0031] Preferably, the first interface 10 and the second interface 11 respectively correspond to the first spiral pitches at both ends of the spiral spring piece 6 .
[0032] It is ensured that the cooling medium has a sufficiently long travel between the spirals of the spiral spring piece 6 (in the spiral cavity 9) to ensure the cooling effect.
[0033] Preferably, if Figure 3 As shown, a stop block 12 is provided on the inner wall of the ring tube 7 , and two stop blocks 12 are respectively provided corresponding to the first spiral pitch at both ends of the spiral spring piece 6 .
[0034] The stop block 12 is used to prevent the spiral spring piece 6 from shrinking at the first interface 10 and the second interface 11 , thereby ensuring the fluidity of the first interface 10 and the second interface 11 .
[0035] Preferably, the first interface 10 close to the tube drawing machine 1 is a feed port.
[0036] The cooling medium enters from a high temperature area and can quickly reduce the temperature.
[0037] Preferably, the external cold source is composed of a water tank and a circulation pump, and the first interface 10, the second interface 11 and the external cold source form a closed loop.
[0038] Preferably, the ring tube 7 is a copper tube.
[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein.
