DETAILED DESCRIPTION

[0023] The specific embodiments of the present application will be further described below in conjunction with the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present application, and cannot be used to limit the protection scope of the present application. EMBODIMENT

[0024] As Figs. 1-4 A cutting and transferring mechanism of a tetrafluoro tube production line, comprising a mounting frame 1, a roller 3 connected with a main shaft of a servo motor 2 arranged above the mounting frame 1, a pipe supporting mechanism fixedly arranged on the outer periphery of the roller 3, the pipe supporting mechanism comprising an arc-shaped supporting plate 4. A driven shaft 5 is arranged on the mounting frame 1 in the same direction as the roller 2 on one side of the roller 2, the driven shaft 5 is fixedly provided with a cutting knife 6, and the blade part of the cutting knife 6 is further provided with an arc-shaped blade part. The main shaft of the servo motor 2 is connected to the driven shaft 5 through a transmission device 7, which can be a belt transmission, but is preferably a chain or a multi-stage reduction gear capable of keeping the transmission direction and finally meshing with the transmission shaft 2. It should be noted that when the pipe is cut in the radial direction, the tetrafluoro tube also moves in the axial direction, but the extrusion speed of the tetrafluoro tube after forming and cooling is relatively slow, and the cutting speed relative to the main shaft of the servo motor can be ignored. In addition, unlike metal pipes, plastic pipes including tetrafluoro tubes are usually connected by on-site fusion welding operation, so slight unevenness of the pipe cutting surface does not affect the technical effect of the present embodiment.

[0025] As a preferred embodiment, the present embodiment further comprises a pipe positioning mechanism, which comprises a worm 8 arranged on the outer periphery of the driven shaft 5, a worm wheel 9 arranged on the mounting frame 1 through a rotating shaft, the worm wheel 9 is adapted to the worm 8, and the worm wheel 9 is further fixedly connected with a positioning member 10, which periodically cooperates with the arc-shaped supporting plate to realize the positioning work of the pipe during the rotation of the worm wheel.

[0026] It should be noted that in order to strictly realize the cooperation function of the present embodiment, the transmission ratio of each gear needs to be strictly adjusted. For example, if three arc-shaped supporting plates 4 are arranged at an angle of 120 degrees in the present embodiment, the positioning member 10 needs to simultaneously realize clamping work when each arc-shaped supporting plate 4 reaches the working position. That is to say, when the cutting knife 6 fixedly arranged on the driven shaft 5 cooperates with the roller 3, the transmission ratio is required to be 1, and the transmission ratio of the worm 8 and the worm wheel 9 is 1 / 3.

[0027] As a preferred embodiment, the side of the positioning member 10 adhering to the pipe member is provided with an arc-shaped shallow groove 11, and the side of the positioning member 10 adhering to the pipe member is provided with a flexible soft pad 12, and a chamfer 13 is arranged at the edge of the arc-shaped shallow groove 11.

[0028] As a preferred embodiment, a sliding plate 16 is fixedly arranged below the driven shaft 5 and the servo motor 2, the sliding plate 16 slides through a plurality of pulleys 14 fixedly arranged below the sliding plate 16 and a guide plate 15 fixedly arranged on the mounting frame 1, and the sliding direction is consistent with the direction of the main shaft of the servo motor, so that the cutting position is adjusted without moving the whole mounting frame, and the operation is more convenient.

[0029] As a preferred embodiment, if a pipe member with a long cutting length is needed, a structure such as a tapered cylinder can be adopted, a large opening is directed to the PTFE pipe production line, a small opening is close to the side of the cutting knife 6, and is directed to the arc-shaped supporting plate 4.

[0030] When the PTFE pipe production line extrudes the PTFE pipe, the PTFE pipe enters the cutting and conveying mechanism from the cutting knife, and the pipe member is sent to the arc-shaped supporting plate in cooperation with the servo motor, the servo motor continues to work, the driven shaft is driven through the transmission device, and the cutting knife rotates, the arc-shaped blade of the cutting knife limits the pipe member at one end of the arc-shaped supporting plate, and the arc-shaped shallow groove of the positioning member also cooperates with the pipe member to be clamped at the other end of the arc-shaped supporting plate due to the transmission effect of the worm and gear, the cutting knife rotates to complete the cutting work, and the positioning member is also driven by the worm and gear to continue to rotate and leave the pipe member, so that the pipe member stays in the arc of the arc-shaped supporting plate, and the pipe member falls from the arc of the arc-shaped supporting plate due to the weight, and can be collected and packaged in a box container without a cover, the cutting and conveying work is completed, the servo motor is stopped, and the next section of pipe reaches the working position and has a proper length, then the servo motor starts to work, and the next arc-shaped supporting plate repeats the above steps, considering the transmission efficiency and the extrusion speed of the PTFE pipe, the main shaft of the servo motor can also reduce the rotating speed through the reduction gear box, increase the torque, and better realize the technical effect.

[0031] The above only describes the preferred embodiments of the present application, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the technical principles of the present application, and these improvements and refinements should also be regarded as the protection scope of the present application.
