Description

Technical Field

[0001] This application relates to the field of tetrafluoro tape processing, and more specifically, to an oil recovery device for the surface of tetrafluoro tape. Background Art

[0002] During the processing of tetrafluoro tape, heating and stretching are required to remove the oil on the tetrafluoro tape outward and ensure the wear resistance of the tetrafluoro tape.

[0003] However, during the heating and stretching of the tetrafluoro tape, the oil on the tetrafluoro tape will evaporate due to heating. After evaporation, it cannot be directly discharged outward, but will instead reattach to the tetrafluoro tape again, resulting in poor quality of the tetrafluoro tape. Summary of the Utility Model

[0030] The present disclosure will be described in detail below with reference to the drawings and in combination with embodiments.

[0031] Refer to Figures 1-4 ,

[0032] A tetrafluoro tape surface oil recovery device includes: a winding member, a heating member, a stretching member, a condensing member, and a suction member.

[0033] The winding member is used to wind the tetrafluoro tape along the winding direction. The winding member includes: a winding roller, a bracket, and a driving motor. The driving motor is installed on the bracket, the winding roller is rotatably connected to the bracket, and the output end of the driving motor is connected to the winding roller. The driving motor drives the winding roller to rotate to realize the winding of the tetrafluoro tape.

[0034] The heating member is used to form a heating chamber for heating the tetrafluoro tape. The heating member includes: a heating plate and a plurality of guide rollers; the tetrafluoro tape sequentially bypasses the plurality of guide rollers; the heating plate is arranged below the guide rollers. The heating member further includes a heating cabinet in which a heating chamber is formed. The tetrafluoro tape sequentially bypassing the plurality of guide rollers can increase the length of the tetrafluoro tape in the heating chamber and improve the heating effect.

[0035] The air intake component transfers the gas in the stretching chamber to the condensation chamber. If the temperature of the PTFE belt in the stretching chamber is too high, the oil in the PTFE belt will evaporate into the stretching chamber. The air intake component directly sucks away the oil-gas mixture in the stretching chamber, thereby preventing the oil-gas mixture from adhering to the PTFE belt in the stretching chamber and avoiding the oil-gas mixture from solidifying into oil droplets after the PTFE belt pulls open the stretching chamber. This also avoids the situation where oil droplets adhere to the PTFE belt after the PTFE belt leaves the stretching chamber, resulting in poor quality of the PTFE belt.

[0036] The stretching component forms the stretching chamber and stretches the PTFE belt. The stretching component includes: a fixed roller, a driving roller, and a driving component; the driving component is used to drive the driving roller to rotate; the fixed roller is fixedly arranged in the stretching chamber; the number of driving rollers is twice that of the fixed rollers; the PTFE belt bypasses the fixed roller and the driving roller; the wrap angle of the PTFE belt in contact with the fixed roller is greater than 160°. A plurality of fixed rollers are provided, and two driving rollers are arranged below each fixed roller; the center distance between the driving rollers is less than the radius of the fixed roller. Among them, the stretching component further includes a stretching cabinet body, and the stretching cabinet body is used to form the stretching chamber. More specifically, the diameter of the driving roller is smaller than that of the fixed roller, and when observed from top to bottom, the driving roller is blocked by the fixed roller. The PTFE belt bypasses the fixed roller. Since the fixed roller is stationary, when the driving roller drives the PTFE belt to convey, the PTFE belt will move relative to the fixed roller. The frictional force between the fixed roller and the PTFE belt is called the resistance to the conveyance of the PTFE belt. The driving roller drives the PTFE belt to convey, so the PTFE belt will be stretched and thinned. The oil-gas mixture in the PTFE belt will be stripped from the PTFE belt due to the thinning of the PTFE belt, and then the air intake component is used to output the oil-gas mixture on the PTFE belt outward.

[0037] The condensation component is used to form the condensation chamber. The condensation component includes a condensation cabinet body, and the condensation chamber is formed in the condensation cabinet body.

[0038] The air intake component is used to transfer the oil-gas mixture in the stretching chamber to the condensation chamber. The air intake component includes an air suction pipe and a pump body; one end of the air suction pipe is communicated with the stretching chamber, and the other end is communicated with the condensation chamber; the pump body is used to add the oil-gas mixture in the stretching chamber to the condensation chamber through the air suction pipe.

[0039] Specifically, the condensation chamber is located below the stretching chamber, and a plurality of oil drain ports are formed at the lower part of the condensation chamber.

[0040] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept. For example, the technical solutions formed by mutually replacing the above features with the technical features (but not limited to) disclosed in the embodiments of the present disclosure that have similar functions.
