Description

Technical Field

[0001] The utility model relates to the field of hollow foam pipe transportation, in particular to a transportation platform for producing thermal insulation pipes. Background Art

[0002] There are many forms of insulation pipes, one of which is a hollow foam tube wrapped around the outer wall of the pipe.

[0003] After the hollow foam tube is formed, it needs to be transported. In the prior art, two conveying discs rotating in opposite directions are generally used to apply a rotational force to the surface of the formed hollow foam tube to realize the movement of the hollow foam tube. In order to adapt to hollow foam tubes of different sizes, the two conveying discs generally use two independent motors to drive the two rotating discs to rotate in opposite directions. This method needs to ensure that the torque generated by the two motors is the same. Otherwise, during the transmission process, the two rotating discs will rotate at different speeds, resulting in tensile cracks on the surface of the hollow foam, resulting in defective products.

[0004] During the operation of the two motors, it is inevitable that there will be deviations in the rotation speed due to usage. Utility Model Content

[0027] The lower parts of the two conveying mechanisms are connected to a spacing adjustment mechanism, which is used to adjust the spacing between the two conveying mechanisms to realize the conveying of hollow foams with different diameters;

[0028] The two conveying mechanisms are connected via a transmission mechanism, and the transmission mechanism is used to realize synchronous reverse rotation of the two conveying mechanisms.

[0029] In this embodiment: firstly, the distance between the two conveying mechanisms is adjusted by the distance adjustment mechanism according to the diameter of the hollow foam tube, and then the two conveying mechanisms are synchronized and rotated in opposite directions through the transmission mechanism to realize the conveyance of the hollow foam.

[0030] Please refer to Figure 1 and Figure 2 The conveying mechanism comprises two symmetrically mounted mounting seats 6, and a conveying disc 7 is rotatably mounted on the inner side of the two mounting seats 6;

[0031] A connecting seat 4 is integrally formed at the bottom end of the mounting seat 6 , and a threaded hole is formed on the connecting seat 4 .

[0032] In this embodiment, when the spacing adjustment mechanism is in operation, the two connecting seats 4 move toward or away from each other until the two connecting seats 4 respectively drive the two conveying plates 7 to move completely, and at this time, the spacing between the two conveying plates 7 is equal to the diameter of the hollow foam.

[0033] Please refer to Figure 1 and Figure 2 The spacing adjustment mechanism includes a screw rod 3 threadedly connected to a screw hole of a connection seat 4, and a positive thread and a negative thread are symmetrically provided on an outer wall of the screw rod 3.

[0035] A forward and reverse motor 2 connected to one end of a screw rod 3 is installed outside the fixed frame 1 .

[0036] In this embodiment: by starting the forward and reverse motor 2, the forward and reverse motor 2 drives the screw 3 to rotate, and at this time the two connecting seats 4 move toward or away from each other along the surface of the screw 3, thereby driving the two conveying mechanisms to move toward or away from each other;

[0037] The two connecting seats 4 move axially synchronously along the surface of the sliding rod 5, and the sliding rod 5 can effectively prevent the conveying mechanism from rotating.

[0038] Please refer to Figure 1 , Figure 2 and Figure 3 The transmission mechanism includes a large synchronous wheel 8, which is connected to the top center of the conveying disc 7. The large synchronous wheel 8 is connected to a small synchronous wheel 10 through a synchronous belt 9. The top of the small synchronous wheel 10 is connected to a core shaft 17, and the top of the core shaft 17 is connected to a gear 13. The two gears 13 are meshed, and the outer wall of the core shaft 17 is rotatably connected to a hollow shaft 11. The outer walls of the two hollow shafts 11 are fixedly connected to a fixing rod 12. The outer wall of the hollow shaft 11 is threadedly connected to a nut 18, and the nut 18 is located above the fixing rod 12;

[0039] An adjusting frame 16 for sliding connection with the hollow shaft 11 is installed at one end of the fixed frame 1. A limit plate in contact with the top of the adjusting frame 16 is integrally formed at the top of the outer wall of the hollow shaft 11. The nut 18 in a tightened state cooperates with the limit plate to limit the position of the hollow shaft 11. A rotating motor 14 is slidably installed at the top of the fixed frame 1. The output end of the rotating motor 14 is connected to the top center of a large synchronous wheel 8, and a through groove 15 for the output shaft of the rotating motor 14 to move is opened on the fixed frame 1.

[0040] In this embodiment: by starting the rotating motor 14, the rotating motor 14 drives a large synchronous wheel 8 to rotate, the large synchronous wheel 8 drives a small synchronous wheel 10 to rotate through the synchronous belt 9, the small synchronous wheel 10 drives the gear 13 on its top to rotate through the mandrel 17, the gear 13 drives another gear 13 to rotate synchronously in the opposite direction, the other gear 13 drives another small synchronous wheel 10 to rotate through another mandrel 17, the other small synchronous wheel 10 drives another large synchronous wheel 8 to rotate through another synchronous belt 9, at this time, the two large synchronous wheels 8 synchronously drive the conveying plate 7 to rotate synchronously and in the opposite direction to convey the hollow foam;

[0041] When adjusting the spacing between the two conveying discs 7, first loosen the nut 18, then start the forward and reverse motor 2, the forward and reverse motor 2 drives the screw 3 to rotate, at this time the two mounting seats 6 respectively drive the two conveying discs 7 to move towards or oppositely, the conveying disc 7 drives the large synchronous wheel 8 to move, at this time the hand contacts the fixed rod 12, applies thrust or pulling force to the fixed rod 12, the fixed rod 12 drives the two hollow shafts 11 to move along the guide groove of the adjustment frame 16, to prevent the synchronous belt 9 from falling off due to being too loose;

[0042] When the conveyor disc 7 is adjusted, the synchronous belt 9 is kept in an effective tension state by pulling the hollow shaft 11, and then the nut 18 is tightened to limit the transmission mechanism;

[0043] When the conveying disc 7 is in motion, one conveying disc 7 drives the rotating motor 14 to move, and the output shaft of the rotating motor 14 moves along the through slot 15. Since the thread is self-locking, the two stopped conveying discs 7 cannot move axially. Then, bolts are used to fix the end plate with screw holes of the rotating motor 14 to the fixed frame 1 to complete the adjustment.
