Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of paper winding equipment, and particularly relates to a roll changing device for a paper machine without shutdown. BACKGROUND

[0002] In the modern paper industry, efficient and continuous production is one of the key factors to improve competitiveness. The stable operation of the paper machine, as the core equipment of the production line, is directly related to the production efficiency and cost control. The paper machine is a large-scale production equipment that converts paper pulp produced in the pulping process into paper through a series of processes such as molding, pressing, drying, etc. It is the core of the paper industry, and its design and performance directly affect the quality, production efficiency and production cost of paper. However, in the existing papermaking process, the manufactured paper is wound by the rotation of the roll. When a certain amount of paper is wound on the roll, the roll needs to be removed by a crane, and another roll needs to be placed in the designated position by the crane, thereby completing the roll changing work.

[0003] Nowadays, the traditional paper machine often needs to be shut down for roll changing operation, which not only interrupts the production process and causes production loss, but also affects the continuity and quality consistency of the paper. Although there are paper machines on the market that can automatically replace the roll, the existing paper machines that automatically replace the roll mainly have glue on the new roll in advance, and then quickly move the new roll close to the paper on the auxiliary roll after the paper is cut off. The new roll sticks to the paper with glue, and then the new roll winds the paper to complete the automatic replacement of the roll of the paper machine. However, the above-mentioned paper machine that automatically replaces the roll has the problem that when the new roll is used to fix and wind the paper with glue, the paper is easily separated from the roll in actual operation, which cannot be connected to the new roll, resulting in the failure of the automatic roll replacement operation of the paper machine. Not only is the stability poor, but also the paper is easily wasted. SUMMARY

[0035] Referring to Figures 8-10 As shown, the processing mechanism comprises the electric sliding rail 20, the electric push rod II 21, the fixing frame 22, the polishing piece 23, the dust collector 24, the guide rail 25 and the supporting block 26; the electric sliding rail 20 is installed on the top of the hollow frame 14, and the electric sliding rail 20 is electrically connected with the controller 18; the electric push rod II 21 is installed on the sliding block of the electric sliding rail 20, and the electric push rod II 21 is electrically connected with the controller 18; the fixing frame 22 is connected to the telescopic rod of the electric push rod II 21; the polishing piece 23 comprises a brushless motor and a polishing wheel, the brushless motor is installed on the fixing frame 22, and the brushless motor is electrically connected with the controller 18, the output shaft of the brushless motor is connected with the polishing wheel, and the polishing wheel is used for polishing the outer wall of the new roll 103; the dust collector 24 is installed on the electric push rod II 21, the dust collector 24 is electrically connected with the controller 18, and the dust collector 24 is used for absorbing the debris generated when the new roll 103 is polished; the guide rail 25 is arranged on the top of the electric sliding rail 20; the supporting block 26 is slidingly connected to the guide rail 25, the supporting block 26 is connected with the dust collector 24 on the top, and the supporting block 26 is used for supporting the dust collector 24.

[0036] When the paper machine body 1 is in the process of placing the new roll 103 and driving the new roll 103 to rotate at high speed, the hollow frame 14, the movable block 15 and the abutment 19 can be driven to move a specified distance to the left by the electric push rod I 13 until the abutment 19 contacts the outer surface of the new roll 103. When the abutment 19 contacts the outer surface of the new roll 103, the outer surface of the new roll 103 will drive the abutment 19 to rotate by friction, and the abutment 19 will detect the outer surface of the new roll 103 to determine whether the outer surface of the new roll 103 contains a protrusion. If the outer surface of the new roll 103 contains a protrusion, when the protrusion on the outer surface of the new roll 103 rotates to contact the corresponding abutment 19, the protrusion will press the corresponding abutment 19 and the movable block 15 to move to the right, the corresponding spring 16 will be compressed, the corresponding movable block 15 will move close to the corresponding distance sensor 17, and when the protrusion on the outer surface of the new roll 103 rotates to separate from the corresponding abutment 19, the corresponding spring 16 will return to its original state, and the corresponding spring 16 will drive the corresponding abutment 19 and the movable block 15 to move to the left to reset. During this period, when the corresponding distance sensor 17 senses that the distance between the corresponding movable block 15 is less than a predetermined value, the corresponding distance sensor 17 will send a signal, and the controller 18 will receive the signal and control the electric sliding rail 20 to drive the electric push rod II 21, the fixed frame 22, the polishing piece 23 and the dust collector 24 to slide forward or backward to a specified position in sequence, so that the polishing piece 23 is above the corresponding movable block 15 in turn. Then the controller 18 will control the electric push rod II 21 to drive the fixed frame 22 and the polishing piece 23 to move to the left, so that the polishing wheel in the polishing piece 23 contacts the outer surface of the new roll 103, and the controller 18 will also control the brushless motor in the polishing piece 23 to drive the polishing wheel to rotate, so that the polishing wheel of the polishing piece 23 polishes the outer surface of the new roll 103. At the same time, the controller 18 will also control the dust collector 24 to open. When the polishing wheel of the polishing piece 23 contacts the protrusion on the outer surface of the new roll 103, the polishing wheel in the polishing piece 23 will polish the protrusion on the outer surface of the new roll 103, and at this time the dust collector 24 will absorb the debris generated during polishing, thereby preventing the debris from scattering on the ground. After a period of time, the controller 18 will control the electric push rod II 21 to drive the fixed frame 22 and the polishing piece 23 to move to the right to reset, and the controller 18 will also control the brushless motor in the polishing piece 23 to stop driving the polishing wheel to rotate, and the controller 18 will also control the dust collector 24 to close. In this way, the area on the outer surface of the new roll 103 with a protrusion can be polished, thereby preventing the protrusion on the outer surface of the new roll 103 from damaging the paper 104 being wound. Then the controller 18 will control the electric sliding rail 20 to drive the electric push rod II 21, the fixed frame 22, the polishing piece 23 and the dust collector 24 to continue to slide forward or backward to a specified position in sequence, and repeat the above operation to polish the next area on the outer surface of the new roll 103 with a protrusion, until the area on the outer surface of the new roll 103 with a protrusion is completely polished. If the new winding roller 103 has no protrusion on its outer surface, the controller 18 will not receive the signal from the distance sensor 17 within the specified time, and then the controller 18 will control the electric push rod I 13 to drive the hollow frame 14, the movable block 15 and the abutting column 19 to move right to reset, so that the abutting column 19 is separated from the outer surface of the new winding roller 103, thereby stopping the rotation of the abutting column 19.

[0037] The above merely describes the specific embodiments of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
