[0003] The existing conveyor belt is driven by a motor to rotate to realize the conveyance of glass tubes. However, since the production process of glass tubes requires the transportation of individual tubes, while the packaging process of glass tubes requires the packaging of whole bundles, the working speeds of the two are different, and the conveyor belt cannot adapt to the production and packaging speeds of glass tubes at the same time, which easily causes the accumulation of glass tubes on the conveyor belt or insufficient supply of glass tubes. In addition, the rotation speeds of the upstream and downstream conveyor belts cannot be strictly synchronized, resulting in the deflection or falling of the glass tubes during the transfer process, causing production losses and affecting the overall packaging efficiency of the glass tubes.

[0026] The technical solution of the utility model is further described below through the accompanying drawings and embodiments.

When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0028] As shown in the figure, a glass tube conveyor belt transfer mechanism includes a frame 1 and a conveyor belt 2 rotatably connected to the frame 1. The upper surface of the conveyor belt 2 is provided with a plurality of U-shaped grooves 3, and the U-shaped grooves 3 are evenly spaced. The width of the U-shaped grooves 3 should match the diameter of the glass tube. When a glass tube falls, the U-shaped grooves 3 on the conveyor belt 2 can stably receive the falling glass tube.

[0029] The conveyor belt 2 is provided with a rotating conveyor belt drive shaft 4 and a conveyor belt driven shaft 5 at both ends, and the conveyor belt drive shaft 4 is provided with a first synchronous pulley 6 and a second synchronous pulley 7 at both ends. The first synchronous pulley 6 is connected to the third synchronous pulley 9 through the first synchronous belt 8, and the second synchronous pulley 7 is connected to the fourth synchronous pulley 11 through the second synchronous belt 10. The diameters of the first synchronous pulley 6, the third synchronous pulley 9 and the fourth synchronous pulley 11 are equal, and a small wheel with 22 teeth can be used. The diameter of the second synchronous pulley 7 is twice the diameter of the fourth synchronous pulley 11, and a large wheel with 44 teeth is selected.

[0030] A first fixed plate 12 and a second fixed plate 13 are symmetrically arranged on both sides of the frame 1. A drive motor 14 is fixedly arranged on the first fixed plate 12. The drive motor 14 can select a servo motor as the power element of the whole device. The output shaft of the drive motor 14 passes through the first fixed plate 12 and is connected to the third synchronous pulley 9.

[0031] A glass tube rotating assembly and a pulley groove wheel mechanism are horizontally arranged between the first fixed plate 12 and the second fixed plate 13. The first fixed plate 12 and the second fixed plate 13 jointly support the glass tube rotating assembly and the pulley groove wheel mechanism above the frame 1. The central axis of the glass tube rotating assembly is flush with the pulley groove wheel mechanism.

[0032] The glass tube rotating assembly is responsible for periodically conveying the glass tubes to the conveyor belt 2 with the U-shaped groove 3. The glass tube rotating assembly includes a rotating roller 15, an outer sleeve 16 and a glass tube group 17. A rotating groove 18 corresponding to the glass tube group 17 is arranged on the peripheral wall of the rotating roller 15. A rotating shaft is arranged through the axis of the rotating roller 15, and one end of the rotating shaft is rotatably connected to the second fixed plate 13.

[0033] The pulley sheave mechanism includes a sheave 19, a double-column pulley 20 and a receiving roller 21. The other end of the rotating shaft passes through the first fixed plate 12. The through end of the rotating shaft is fixedly provided with a sheave shaft 22. The sheave 19 is rotatably connected to the outside of the sheave shaft 22. The diameters of the sheave 19 and the double-column pulley 20 are the same. Specifically, in order to cooperate with four synchronous pulleys, the size of the sheave 19 and the double-column pulley 20 can be selected to be 113.14 mm.

[0034] One end of the receiving roller 21 is connected to the pulley shaft 24 through a flange bearing 23, and the other end of the receiving roller 21 is connected to the fourth synchronous pulley 11 through a flange bearing 23. The double-column pulley 20 is rotatably connected to the outside of the pulley shaft 24. The sheave 19 installed on the sheave shaft 22 cooperates with the double-column pulley 20 installed on the pulley shaft 24 to convert the continuous rotary motion of the sheave 19 into the intermittent motion of the double-column pulley 20. The driving motor 14 (servo motor) rotates to drive the four synchronous pulleys and two synchronous belts, and transmits power to the sheave shaft 22, the pulley shaft 24, and the transmission belt drive shaft 4.

[0035] The device of the utility model needs an external controller when working, and the controller controls the start and stop of the driving motor 14. When the driving motor 14 is started, the third synchronous pulley 9 rotates to drive the first synchronous belt 8 to rotate, and then drives the first synchronous pulley 6 to rotate. At this time, the conveyor belt drive shaft 4 rotates synchronously to drive the conveyor belt 2 (U-shaped groove 3) and the second synchronous pulley 7 to rotate in the same direction and at the same speed.

[0036] As the second synchronous pulley 7 rotates, it drives the fourth synchronous pulley 11 to rotate, and then drives the grooved wheel shaft 22 and the grooved wheel 19 to rotate at twice the same speed. The grooved wheel 19 and the double-column dial wheel 20 form a dial-wheel and grooved wheel mechanism, which converts the uniform circular motion of the double-column dial wheel 20 into intermittent circular motion at the grooved wheel 19. The grooved wheel 19 drives the grooved wheel shaft 22 and the rotating roller 15 to rotate 1 / 4 circle per cycle. During the time when the grooved wheel 19 stops rotating, the glass tube that has rotated 1 / 2 in the outer sleeve 16 slides out from the opening at the lower end of the outer sleeve 16 and is accurately received by the U-shaped groove 3 on the conveyor belt 2. At the same time, the new glass tube enters the rotating roller 15 to complete a receiving action.

[0037] Therefore, the utility model adopts the above-mentioned glass tube conveyor belt switching mechanism, adopts a dial wheel groove wheel mechanism to control the periodic output of the glass tube switching, gives the glass tube enough time to enter and release, and further improves the success rate of the switching.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
