Description

Technical Field

[0001] The present invention relates to the technical field of paper roll processing, and in particular to a paper roll cutting machine. Background Art

[0002] To protect the environment and save energy and costs, waste paper rolls generated during paper mill production must be processed. Most waste paper rolls are broken up in waste paper roll processing lines and then fed into pulpers for recycling. Currently, most domestic waste paper roll processing lines use paper splitters, which employ hydraulically driven splitters to split the paper rolls down the middle and then feed the split rolls in batches into the pulping tank. While this method is quick and convenient, it has certain limitations.

[0003] First, the split paper rolls are sent into the pulping pool in batches, so there are high requirements for the performance of the conveyor and pulper; second, the paper splitting machine can only perform paper splitting operations in a fixed place. The paper rolls need to be fed in by the conveyor, and then sent out by the conveyor after the paper rolls are split. It occupies a large area and cannot be installed and used in some narrow spaces. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the present invention provides a paper roll cutting machine, which has the advantage of being able to cut a waste paper roll into sheets of paper on a pulper, thereby solving the problems in the background art.

[0046] The cutting assembly 4 is installed inside the traveling frame 21 through the mounting frame 5 and is located directly above the paper roll lifting assembly 3. The cutting assembly 4 includes a lifting unit 41, a transverse drive unit 42, and a cutter unit 43.

[0048] See also Figure 1 、 Figure 4 and Figure 5The horizontal drive unit 42 includes a synchronous pulley 422 , a synchronous belt 423 is provided on the synchronous pulley 422 , and the horizontal drive unit 42 includes a horizontal drive motor 421 for driving the synchronous belt 423 .

[0049] See also Figure 1 、 Figure 4-Figure 7 The cutter unit 43 includes a cutter frame 431, which is mounted on the synchronous belt 423, and a plow 433 is provided at the bottom of the cutter frame 431, and a circular cutter 432 is provided in the center of the plow 433, and the circular cutter 432 is mounted on the cutter frame 431 through a bearing.

[0050] The cutting assembly 4 further includes an air blowing assembly 44, which includes a pneumatic rotary joint 441, a spiral air pipe 442 installed on the pneumatic rotary joint 441, and the end of the spiral air pipe 442 is installed on the plow blade 433 through an air blowing head 445;

[0051] A guide frame 444 for guiding a spiral air pipe 442 is installed on the cutter frame 431 , and a protective cover 443 is provided on the spiral air pipe 442 .

[0052] See also Figure 1 and Figure 2 The top of the traveling frame 21 is provided with a slide rail 23 , a centering slider 25 , and a centering motor 24 for driving the centering slider 25 to move on the slide rail 23 .

[0053] A traveling wheel and a traveling motor 22 for driving the traveling wheel are provided at the bottom of the traveling frame 21 , and the traveling wheel is in rolling connection with the track 1 .

[0054] See also Figure 1 and Figure 3 The paper roll lifting assembly 3 includes two elevators, both of which are installed on the centering slider 25.

[0055] The elevator includes a paper roll lifting frame 31 , a lifting frame 32 is provided on the inner side of the paper roll lifting frame 31 near the bottom, and a lifting motor 33 is provided on the top of the paper roll lifting frame 31 for lifting the lifting frame 32 .

[0056] When using the present invention:

[0057] The centering motor 24 in the walking assembly 2 is started, so that the centering slider 25 carries the two elevators in the paper roll lifting assembly 3 to move closer to each other to clamp the paper roll. The centering motor 24 and the centering slider 25 can be driven by a synchronous pulley 422 or a sprocket through a chain or a synchronous belt 423.

[0058] After the paper roll is sent to the walking frame 21, the two elevators in the paper roll lifting assembly 3 clamp the paper roll through the lifting frame 32. One of them can simply realize the centering of the paper roll, and the other can limit the lateral movement of the paper roll to prevent the paper roll from moving laterally during the subsequent lifting process and paper cutting process, causing the risk of the paper roll falling and affecting the cutting effect of the cutter, resulting in the inability to cut the paper roll smoothly. After the paper roll is cut, the left and right elevators are opened to allow the paper roll core to fall or be removed manually.

[0059] The lifting motor 33 in the paper roll lifting assembly 3 drives the paper roll lifting frame 31 to rise and fall at various speeds. Specifically, the lifting motor 33 drives the sprocket to drive the chain paper roll lifting frame 31 up and down. The paper roll lifting frame 31 uses multiple sets of combined bearings for joint guidance. This structure greatly increases the guiding stroke of the paper roll lifting frame within a limited space to meet the demand for a large lifting stroke of the paper roll lifting frame 31 in certain projects. The lifting motor 33 shaft end is equipped with an encoder that can calculate the movement distance of the lifting frame in real time and use control measures to meet the synchronization requirements of the left and right paper roll lifting frames 31. The paper roll lifting frame 31 is equipped with a small counterweight block and is guided by a guide rail to ensure that the chain is always in a tensioned state. The sprocket is equipped with a chain pressure block to prevent the chain from falling off the sprocket.

[0060] The cutting assembly 4 uses the lifting motor 411 in the lifting unit 41 to drive the cutter unit 43 to move up and down. The cutter unit 43 is equipped with a corresponding light switch for knife adjustment. When the light switch detects the paper roll, it means that the cutter unit 43 has been lowered into place and the paper roll cutting process can begin. The cutting depth of the paper roll cut by the cutter can be adjusted in real time through the program as needed, thereby reducing cutter wear. The cutter unit 43 is raised and lowered by a chain or a synchronous belt 423, and is guided by a single-sided combined bearing and a single-sided linear guide rail, which can effectively reduce the processing difficulty while ensuring the guiding accuracy. In addition, the device uses a spiral air pipe 442 to realize the stretching and contraction function of the air pipe, and uses a pneumatic rotary joint 441 to realize the air pipe rotation function when the cutter unit 43 moves back and forth. An air pipe protective sleeve 443 is also added to the air pipe to protect the air pipe from wear. This design can save the use of drag chains and the length of the air pipe. It is simple and convenient and can effectively reduce the cost of equipment.

[0061] The cutting assembly 4 uses a horizontal drive motor 421 in the horizontal drive unit 42 to drive a synchronous pulley 422, and the synchronous belt 423 is used to transmit the cutter unit 43 to move back and forth horizontally to complete the paper cutting function.

[0062] The cutter unit 43 consists of a circular cutter 432, a plow blade 433, a cutter frame 431, an air blow head 445, etc. The circular cutter 432 is connected to the cutter frame 431 through a shaft, bearings, etc. When cutting paper, the circular cutter 432 can rotate flexibly to prevent paper jams. The plow blade 433 has a structure that is narrow in front and wide in the back. After the circular cutter 432 cuts off the paper roll layer, it sometimes cannot fall smoothly. At this time, the plow blade 433 is needed to plow the paper roll open so that the paper pieces can fall smoothly. The air blow head 445 is fixed on the plow blade 433. When the cutter unit 43 moves, the air blow component 44 works to blow off the paper pieces that have not fallen. Multiple measures are taken to ensure that the paper pieces can fall smoothly during the cutting process.

[0063] The foregoing is merely an embodiment of the present invention and is not intended to limit the present invention. It will be apparent to those skilled in the art that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
