The extension rod 38 drives the locking block 37 to move out of the locking groove 36. At this time, the second spring pops out the auxiliary block 40 to block the locking block 37, so that the locking block 37 cannot move out of the square shell 35 under the elastic force of the first spring, so that the locking block 37 cannot affect the up and down movement of the movable plate 23.

When the square rod 141 rotates, the outer wall of the square rod 141 is fixedly connected to the sixth bevel gear 45; one end of the outer wall of the third rotating rod 44 is fixedly connected to the seventh bevel gear 46, and the seventh bevel gear 46 and the sixth bevel gear 45 mesh with each other, so that the rotation of the square rod 141 drives the third rotating rod 44 to rotate through the sixth bevel gear 45 and the seventh bevel gear 46, so that the rotation of the third rotating rod 44 drives a group of quantitative plates 47 to rotate, so that when the raw material falls into the extrusion shell 2 through the connecting shell 7 in the raw material box 6, it will be blocked by the quantitative plates 47, so that the raw material will be accumulated on the quantitative plates 47, and as the quantitative plates 47 follow the rotation of the third rotating rod 44, the raw material will quantitatively enter the extrusion shell 2 with the rotation of the quantitative plates 47, so that the device has the function of quantitative unloading, making the unloading of the device more accurate, and through automatic and continuous unloading, the production accuracy of the device is higher, and the stability of the operation is guaranteed.
[0039] When the present invention is in use, the raw material is put into the raw material box 6 from the discharge port 8 on the raw material box 6, and the raw material will fall into the extrusion shell 2 through the connecting shell 7. At this time, the motor 4 drives the screw body 5 to rotate, so that the rotation of the screw body 5 drives the raw material to move toward the extrusion head body 3, until it is extruded from the extrusion head body 3 to form the initial state of the Teflon tube, and when the screw body 5 rotates, it will drive the first bevel gear 13 to rotate. Because the bottom end of the outer wall of the rotating rod 14 is fixedly connected to the second bevel gear 15, and the second bevel gear 15 is meshed with the first bevel gear 13, the rotation of the first bevel gear 13 drives the rotating rod 14 to rotate through the second bevel gear 15. The top of the outer wall of the side wall and the rotating rod 14 is fixedly connected with a sprocket 16, and the pair of sprockets 16 are connected by a chain 11, so that the rotation of the rotating rod 14 drives the round rod 10 to rotate through the sprocket 16 and the chain 11, and the round rod 10 drives the stirring plate 12 to rotate, so that the device can stir the raw material while extruding the raw material. Since stirring and extrusion are carried out at the same time, the device can ensure the quality of the Teflon tube while ensuring the molding efficiency of the Teflon tube. Since the rotating rod 14 includes a square rod 141 and a round shell 142, the rotation of the second bevel gear 15 will drive the square rod 141 to rotate, and the square rod 141 drives the round shell 142 to rotate. The outer wall of the square rod 141 is fixedly connected to the round shell 142, and the third bevel gear 19 is fixedly connected to the outer wall of the square rod 141; the first rotating rod 20 is rotatably connected to one side of the outer wall of the raw material box 6; the fourth bevel gear 21 is fixedly connected to one end of the outer wall of the first rotating rod 20, and the fourth bevel gear 21 is meshed with the third bevel gear 19, so that the rotation of the square rod 141 will drive the first rotating rod 20 to rotate through the third bevel gear 19 and the fourth bevel gear 21. Because the outer wall of the first rotating rod 20 is provided with a water drop block 22, the rotation of the first rotating rod 20 drives the water drop block 22 to rotate. Due to the shape of the water drop block 22, the rotation of the water drop block 22 causes the moving plate 23 to fit the outer surface of the water drop block 22, so that the rotation of the water drop block 22 drives the moving plate 23 to fit the outer surface of the water drop block 22 The plate 23 slides up and down on one side of the outer wall of the raw material box 6, so that the up and down movement of the movable plate 23 drives the connecting plate 9 to move up and down, so that the connecting plate 9 drives the circular rod 10 and the circular shell 142 to move up and down, so that the circular shell 142 slides up and down on the outer side wall of the square rod 141, and the circular rod 10 slides up and down on the top of the outer wall of the raw material box 6, and the circular shell 142 and the circular rod 10 are rotatably connected to the connecting plate 9, so that the circular rod 10 can still drive the stirring plate 12 to rotate, and the stirring plate 12 rotates and moves up and down, thereby not only increasing the stirring range of the stirring plate 12, but also increasing the stirring effect of the device, and because the outer wall bottom end of the circular rod 10 is rotatably connected with the cross plate 42;The outer wall of the cross plate 42 is fixedly connected with a cleaning plate 43, so that the up and down movement of the round rod 10 will drive the cross plate 42 and the cleaning plate 43 to move up and down, so that the up and down movement of the cleaning plate 43 can scrape off the raw materials adhering to the inner wall of the raw material box 6, thereby reducing the waste of raw materials and making it difficult for the raw materials to be uneven due to part of the raw materials adhering to the inner wall of the raw material box 6. In addition, since the top of the outer wall of the cleaning plate 43 is provided with an inclined surface, the cleaning plate 43 can scrape off the raw materials adhering to the inner wall of the raw material box 6 more efficiently. The square rod 141 is convenient to use, and when the square rod 141 rotates, the outer wall of the square rod 141 is fixedly connected with the sixth bevel gear 45; one end of the outer wall of the third rotating rod 44 is fixedly connected with the seventh bevel gear 46, and the seventh bevel gear 46 and the sixth bevel gear 45 are meshed with each other, so that the rotation of the square rod 141 drives the third rotating rod 44 to rotate through the sixth bevel gear 45 and the seventh bevel gear 46, so that the rotation of the third rotating rod 44 drives a group of quantitative plates 47 to rotate, so that when the raw material falls into the extrusion shell 2 through the connecting shell 7 in the raw material box 6, it will be blocked by the quantitative plates 47, so that The raw materials will be accumulated on the quantitative plate 47, and as the quantitative plate 47 follows the rotation of the third rotating rod 44, the raw materials will be quantitatively entered into the extrusion shell 2 as the quantitative plate 47 rotates, so that the device has the function of quantitative material discharging, making the material discharging of the device more accurate, and through automatic continuous material discharging, the production accuracy of the device is higher, and the stability of the operation is guaranteed, and the square plate 30 is rotatably connected to the top of the outer wall of the circular rod 10; the bottom end of the outer wall of the square plate 30 is rotatably connected to a pair of second symmetrical about the center line of the circular rod 10 The rotating rod 31 drives the square plate 30 and the pair of second rotating rods 31 to move up and down when the circular rod 10 moves up and down. Because the outer side walls of the pair of second rotating rods 31 and the circular rod 10 are fixedly connected with fifth gears 32, and the set of fifth gears 32 are meshed with each other, the rotation of the circular rod 10 drives the pair of second rotating rods 31 to rotate through the set of fifth gears 32, and the rotation direction of the pair of second rotating rods 31 is opposite to the rotation direction of the circular rod 10, and a set of first through grooves 33 are opened on one side of the outer wall of the set of stirring plates 12;A pair of second rotating rods 31 are fixedly connected to the outer side wall of one end of the raw material box 6 with a group of auxiliary plates 34, and the two groups of auxiliary plates 34 are matched with a group of stirring plates 12 and the first through groove 33 respectively, so that the rotation of the round rod 10 will drive the stirring plate 12 to rotate, and the pair of second rotating rods 31 will drive the auxiliary plates 34 to rotate. Because the auxiliary plates 34 and the stirring plates 12 rotate in opposite directions, the raw materials will collide with each other under the opposite stirring and rotating forces, thereby not only further improving the stirring effect, but also preventing the raw materials from remaining relatively stationary under the rotation of the same force, which reduces the stirring effect of the raw materials, and the second rotating rods 31 and the square plates 30 will follow the round rods 10 The auxiliary plate 34 also moves up and down while rotating, and the stirring resistance of the stirring plate 12 is reduced through the first through groove 33 on the stirring plate 12, and the stirring effect is better through the cooperation of the auxiliary plate 34. When the raw material in the raw material box 6 is small and the stirring plate 12 does not need to be moved up and down for stirring, or when the raw material in the raw material box 6 is large and a larger up and down range is required for stirring, the water drop block 22 includes the first half block 221 and the second half block 222, so that the device can release the fixation of the fixing block 27 by rotating the bolt 29 to move the bolt 29 out of the threaded through groove 28, so that the first half block 221 and the second half block 222 are released. At this time, the fixing block 27 on the second half block 222 is moved out of the fixing groove 26 on the first half block 221, and the limiting blocks 25 on the first half block 221 and the second half block 222 are also moved out of the pair of limiting grooves 24 on the first rotating rod 20. At this time, the water drop block 22 is disassembled, so that the movable plate 23 will no longer move up and down due to the rotation of the water drop block 22, and the connecting plate 9 will not move up and down, so that the circular rod 10 and the stirring plate 12 and the auxiliary plate 34 will not move up and down, but will only rotate. Therefore, when there is less raw material and the stirring plate 12 is not needed to move up and down for stirring, the water drop block 22 can be disassembled to make the stirring plate 12 and the auxiliary plate 34 rotate in place. When there are more raw materials in the material box 6 and a larger up-and-down range is required for stirring, a larger water drop block 22 can be installed to make the moving plate 23 and the connecting plate 9 move up and down with a larger range, so that the stirring plate 12 and the auxiliary plate 34 can move up and down with a larger range, so that the device can adjust the up-and-down stirring range of the stirring plate 12 or whether to move up and down for stirring according to the amount of raw materials and the stirring needs, making the device more practical and more flexible, so that it can cope with a variety of stirring environments, and when the water drop block 22 is removed and the stirring plate 12 only rotates but does not move up and down, a square shell 35 is fixedly connected to one side of the outer wall of the moving plate 23;A group of latching grooves 36 are provided on one side of the outer wall of the raw material box 6, so that the device can latch the latching blocks 37 on the square shell 35 into the latching grooves 36 on the raw material box 6 to fix the movable plate 23 to the raw material box 6. When the device vibrates due to operation, the movable plate 23 is fixed to the raw material box 6, so that the vibration cannot cause the stirring plate 12, the round rod 10 and the connecting plate 9 to fluctuate up and down, so that the connecting plate 9 and the stirring plate 12 will not shake due to vibration, so that the connecting plate 9 and the stirring plate 12 are not easily damaged by vibration, and the stirring plate 12 is more stable during stirring. In addition, by latching the latching blocks 37 into the latching grooves 36 of different heights, the stirring plate 12 can be located at different heights for stirring, so that the device can adjust the stirring plate 12 according to needs. The stirring position makes the stirring effect of the stirring plate 12 better. When the stirring plate 12 needs to move up and down while rotating, the stretching rod 38 is pulled to drive the locking block 37 to move out of the locking groove 36. At this time, the second spring pops out the auxiliary block 40 to block the locking block 37, so that the locking block 37 cannot move out of the square shell 35 under the elastic force of the first spring, so that the locking block 37 cannot affect the up and down movement of the moving plate 23. The auxiliary block 40 is matched with the locking block 37, so that when the locking block 37 is locked in the locking groove 36, the auxiliary block 40 will be locked between the square shell 35 and the locking block 37 under the action of the second spring, so that the vibration force cannot move the locking block 37 out of the locking groove 36, thereby ensuring the stability of the locking block 37. ;
