Description

Technical Field

[0001] This utility model relates to the field of paper winding technology, and in particular to an automatic paper roll unloading device. Background Technology

[0002] After paper is produced or cut, it needs to be wound onto paper tubes for storage and transportation. Currently, paper winding is generally done by winding machines.

[0003] Current winding machines typically use an air shaft to lock the roll, and then rotate the air shaft to perform the winding operation. However, after winding is completed, it is usually necessary for the operator to control the air shaft to leave the roll, manually push the paper roll away, and then place and rewind a new roll. This is cumbersome and has a low degree of automation, requiring a lot of manual operation from the operator. Therefore, improvements are needed, and an automatic paper roll unloading device is required. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Reference Figures 1-3 According to an embodiment of the automatic paper roll feeding device of the present invention, it includes a support component 91, a pushing component 92 and a winding component. The paper roll formed by the winding component is supported by the support component 91 and pushed down by the pushing component 92 for automatic feeding.

[0028] Specifically, the support assembly 91 includes a first support frame 11, on which an installation frame 12 is provided, and the installation frame 12 contains two load-bearing rollers 14 distributed on the left and right, that is, the load-bearing rollers 14 can be used to support the paper roll.

[0029] Two vertical plates 15 are fixed on the first support frame 11, and the two vertical plates 15 are respectively fixed to the front and rear sides of the mounting frame 12. The pushing assembly 92 includes two bent plates 16 distributed front and rear. The bends in the two bent plates 16 are respectively rotatably connected to the sides of the front and rear distributed vertical plates 15. A push roller 17 is rotatably connected between the two bent plates 16. The push roller 17 is mounted on the lower edge of the bent plate 16 and is located above the bearing roller 14. It also includes a first drive mechanism for controlling the angle of the bent plate 16.

[0030] After the paper roll is placed between the two carrier rollers 14 and the winding is completed, the operator can use the first drive mechanism to drive the bending plate 16 to swing to the right. At this time, the push roller 17 will push the paper roll placed between the carrier rollers 14 down.

[0031] In this embodiment, the first drive mechanism includes a first cylinder seat hinged to the side of each of the vertical plates 15. A first piston cylinder 18 is fixed on the first cylinder seat, and the end of the first piston rod in the first piston cylinder 18 is hinged to the upper edge of the bending plate 16. That is, when the first piston rod in the first piston cylinder 18 is pushed out, the bending plate 16 will rotate counterclockwise by a certain angle, causing the push roller 17 to move to the right. At this time, the push roller 17 will abut against the paper roll located on the carrying roller 14 and push it down. After the pushing operation is completed, the bending plate 16 is reset to avoid interfering with the subsequent winding operation.

[0032] In a second embodiment of the automatic paper roll feeding device, to prevent the paper roll pushed down by the push roller 17 from hitting the ground and to improve the quality of the paper roll, a receiving component 93 is also included. The receiving component 93 includes a second support frame 19, with two second support frames 19 arranged front and rear. A mounting base is fixed on the second support frame 19, and a triangular plate 20 is hinged in the mounting base. A transition plate 21 is integrally formed between the two triangular plates 20, and a baffle 22 extending to the upper right is integrally formed on the right edge of the transition plate 21. The transition plate 21 and the baffle 22 have an arc transition. The device also includes a second drive mechanism for controlling the angle of the triangular plate 20 and the transition plate 21.

[0033] The paper roll pushed down by the push roller 17 is supported by the transition plate 21 and blocked by the baffle 22 to prevent it from rolling down. Then, the second drive mechanism drives the transition plate 21 and the baffle 22 to tilt to the right and downward so that the paper roll on it rolls down slowly. The two triangular plates 20 are located between the two second support frames 19, that is, the distance between the triangular plates 20 is smaller than the distance between the second support frames 19, so that the baffle 22 can be in contact with the ground after tilting to the right and downward, so as to prevent the paper roll from being hit.

[0034] In this embodiment, the second drive mechanism includes a second cylinder seat fixed on the second support frame 19, a second piston cylinder 23 is hinged on the second cylinder seat, and the second piston rod in the second piston cylinder 23 extends to the upper left and is hinged to the triangular plate 20.

[0035] For winding operations, the winding assembly includes a drive box 24, which contains two No. 1 motors. The two output shafts of the two No. 1 motors are respectively connected to the two carrier rollers 14.

[0036] Furthermore, the winding assembly also includes a slide block 25 that is slidably connected to the vertical plate 15. The vertical plate 15 contains a fourth piston cylinder 30. The end of the fourth piston rod extending vertically in the fourth piston cylinder 30 is connected to the slide block 25. A sliding sleeve 26 is slidably connected to the slide block 25, and a roll support roller 27 is rotatably connected to the sliding sleeve 26. A third piston cylinder 28 is also fixedly installed in the slide block 25. The third piston rod in the third piston cylinder 28 extends forward and backward and is connected to the sliding sleeve 26 through a connecting frame 29.

[0037] During winding, the roll is placed between the support rollers 14, and the sliding sleeve 26 is controlled by the third piston cylinder 28 to insert the roll support roller 27 into the roll. Then the support rollers 14 rotate and drive the paper tube to rotate and perform the winding operation.

[0038] To prevent the drum located between the bearing rollers 14 from spinning idly, a pressing assembly is also included. The pressing assembly includes a lifting frame 31 that is slidably connected between the vertical plates 15. A pressing roller 32 is rotatably connected inside the lifting frame 31. The assembly also includes a lifting motor for controlling the lifting frame 31.

[0039] Specific workflow:

[0040] The worker places the roll between the carrying rollers 14, manually wraps a certain number of layers of paper around it, and then begins the winding process. At this time, the pressure roller 32 presses against the outside of the paper roll, and the carrying rollers 14 rotate. The roll begins the winding process during the rotation, and the slide block 25 gradually moves upward during this process.

[0041] After the winding is completed, the carrier roller 14 stops rotating and the lifting frame 31 moves upward. Then, the first piston cylinder 18 controls the bending plate 16 to rotate counterclockwise, so that the push roller 17 pushes the paper roll located on the carrier roller 14 to move to the right. At this time, the paper roll will be pushed onto the transition plate 21, and then the push roller 17 will reset.

[0042] Then the second piston rod in the second piston cylinder 23 retracts, and the transition plate 21 and the second piston cylinder 23 tilt to the lower right until the baffle 22 touches the ground. During this process, the paper roll on the transition plate 21 will roll off, and the unloading operation is completed.

[0043] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
