[0023] The following further elaborates on the present utility model with reference to the accompanying drawings.

[0024] A roller type pipe receiving and discharging rack, asFigure 1 As shown, it includes a plurality of driving rollers 1 and a plurality of driven rollers 2. Both the driving rollers 1 and the driven rollers 2 are V-shaped wheels. It further includes a straight beam 3, and the plurality of driving rollers 1 and the plurality of driven rollers 2 are arranged along the same straight line on the straight beam 3. It also includes two columns 4, and threaded lifting adjustment components are provided on both columns 4. The two ends of the straight beam 3 are respectively fixed to the two threaded lifting adjustment components.

[0025] In this application, a plurality of driving rollers 1 and driven rollers 2 are integrally arranged in a straight line through the straight beam 3. On the premise of ensuring the straightness of the plurality of driving rollers 1 and driven rollers 2, only the height of the straight beam 3 needs to be adjusted through the threaded lifting adjustment component, and then the center distance of the V-shaped jaws of each roller can be adjusted synchronously, so as to achieve the technical effect of adapting to various paper tube diameters and effectively improve the adaptability of this application.

[0026] The driving rollers 1 and the driven rollers 2 are installed on the straight beam 3 in the following manner. As Figure 2 、 Figure 3 shown, a plurality of bearing seats 5 are bolted to the straight beam 3. A blanking control rotating shaft 6 is rotatably connected to the plurality of bearing seats 5 through bearings. A roller assembly seat 7 is fixedly clamped to the blanking control rotating shaft 6 corresponding to each driving roller 1 and driven roller 2. The plurality of driving rollers 1 and the plurality of driven rollers 2 are respectively axially connected to the corresponding roller assembly seats 7. Through the blanking control rotating shaft 6, on the premise that the plurality of driving rollers 1 and the plurality of driven rollers 2 are arranged in a straight line along the straight beam 3, the plurality of driving rollers 1 and the plurality of driven rollers 2 are given the ability to swing synchronously around the blanking control rotating shaft 6, thus facilitating blanking.

[0027] The action control structure for receiving and blanking in this application is specifically as follows. As Figure 1 Figure 3 shown, a cylinder connection seat 8 is bolted to the straight beam 3. A cylinder connection bent arm 9 is fixedly sleeved on the blanking control rotating shaft 6. A blanking control cylinder 10 is arranged between the cylinder connection seat 8 and the cylinder connection bent arm 9. The sleeve end of the blanking control cylinder 10 is rotatably connected to the cylinder connection seat 8, and its piston rod end is rotatably connected to the cylinder connection bent arm 9. A plurality of rolling inclined guide plates 11 are bolted to the straight beam 3 at the unloading section.

[0028] In the material receiving state, the blanking control cylinder 10 is in a contracted state, making the central axes of the active rollers 1 and the passive rollers 2 parallel to the horizontal plane. Thus, the connecting line of the centers of the V-shaped clamping openings of the rollers is collinear with the feeding direction of the paper tube, ensuring the stable material receiving of the paper tube. After the material receiving is completed and the paper tube is guided to the predetermined position, the piston rod of the blanking control cylinder 10 extends, applying a thrust to the movable end of the cylinder connecting bent arm 9, thereby driving the blanking control rotating shaft 6 to rotate, forcing the active rollers 1 and the passive rollers 2 to gradually swing and tilt until the paper tube is supported by the rolling inclined guide plate 11 and rolls along the inclination angle of the rolling inclined guide plate 11, completing the blanking of the paper tube. In summary, by only controlling the telescopic movement of the blanking control cylinder 10, the material receiving state and automatic blanking can be efficiently switched, achieving the technical effect of convenient control.

[0029] To control the forward distance of the controllable paper tube in this application, as Figure 1 、 Figure 3 shown, a material blocking base 12 is provided at the receiving end of the straight beam 3. The material blocking base 12 is provided with a baffle shaft 13, and a tail baffle 14 is rotatably connected to the baffle shaft 13. The material blocking base 12 is provided with a baffle control cylinder 15, and the piston rod end of the baffle control cylinder 15 is rotatably connected to the tail baffle 14. By driving the tail baffle 14 to swing and controlling its angle with the baffle control cylinder 15, the paper tube can be blocked at different positions, thereby realizing the controllability of the receiving end of the paper tube.

[0030] In this application, the rotation of the active roller 1 is required to push the paper tube forward by using friction. The rotation power structure of the active roller 1 is as follows, as Figure 1 、 Figure 2 shown, a motor mounting plate 16 is fixed to the blanking control rotating shaft 6. A power motor 17 is fixedly installed on the motor mounting plate 16. At least two shaft mounting plates 18 are fixed to the blanking control rotating shaft 6. The shaft mounting plates 18 are rotatably connected to the motor shaft 19 through ball bearings. The motor shaft 19 is connected to the power motor 17 through a speed reducer. Belt drive assemblies 20 are respectively arranged between the motor shaft 19 and each active roller 1. During the material receiving process, the power motor 17 drives the motor shaft 19 to rotate. During the rotation of the motor shaft 19, multiple belt drive assemblies 20 are used to synchronously drive the rotation of multiple active rollers 1, ensuring the rotational speed consistency of multiple active rollers 1 while meeting the requirements of pushing the paper tube.

[0031] As Figure 1 、 Figure 4 shown, this application further includes a chassis 21. Two columns 4 are respectively fixed to the chassis 21. The chassis 21 is installed with multiple self-locking universal wheels 22, endowing this application with the ability to move and improving the convenience for connecting to the discharging end of the paper tube machine.

[0032] The specific structure of the threaded lifting and adjusting assembly is as follows, as Figure 4As shown in the figure, the screw lift adjustment assembly includes a support sleeve 23 fixed to the column 4, an internally threaded shaft 24 that is rotationally restricted and slidably inserted into the support sleeve 23, and an externally threaded shaft 25 that is in threaded engagement with the internally threaded shaft 24. An assembly disc 26 is provided at the top end of the internally threaded shaft 24, and the linear beam 3 is fixed to the assembly disc 26. When it is necessary to adjust the height of the linear beam 3, only by driving the externally threaded shaft 25 to rotate, a screw propulsion force can be generated in cooperation with the internally threaded shaft 24, thereby pushing the internally threaded shaft 24 to slide up and down along the support sleeve 23, and further controlling the height of the linear beam 3. It has the functions of stable lifting and screw self-locking.

[0033] To ensure the height consistency at both ends of the linear beam 3, as Figure 4 shown in the figure, a driving gear shaft 27 is rotatably connected through the two columns 4. A driving helical gear 28 is fixed to the keyway of the driving gear shaft 27, and a driven helical gear 29 that meshes with the driving helical gear 28 is fixed to the keyway at the bottom end of the externally threaded shaft 25. Thus, only by driving the driving gear shaft 27 to rotate, the externally threaded shaft 25 can be driven synchronously and at a constant speed through the transmission of the two sets of driving helical gears 28 and driven helical gears 29, effectively ensuring the consistency of the lifting at both ends of the linear beam 3 and preventing it from tilting.

[0034] In this embodiment, as Figure 4 shown in the figure, an internal corrugated handwheel 30 is installed at any end of the driving gear shaft 27, so that the worker can manually rotate the driving gear shaft 27. In other embodiments, a servo motor can also be used to drive the driving gear shaft 27.

[0035] The specific embodiments are only explanations of the present invention, and they do not limit the present invention. After reading this specification, those skilled in the art can make modifications to the embodiments without creative contributions as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
