Description

Technical Field

[0001] The present invention particularly relates to a paper rolling system and a paper rolling method for paper production. Background Art

[0002] Rolling the produced paper is an important step in paper production. Although the existing paper processing rolling device has achieved basic operating performance, it still has the following defects:

[0003] 1. As the paper roll gets thicker, the speed of the paper roll will get faster. How to make the paper conveying machine match this speed is an urgent problem to be solved.

[0004] 2. If paper is rolled or stuck to foreign objects during the paper rolling process, it will be difficult to remedy the problem in subsequent processes if it is not discovered immediately and the paper is not rolled up. How to discover this problem immediately needs to be solved urgently.

[0005] In summary, the present application proposes a paper rolling system and a paper rolling method for paper production to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a paper rolling system and a paper rolling method for paper production in view of the deficiencies in the prior art, and the paper rolling system and the paper rolling method for paper production can well solve the above-mentioned problems.

[0007] In order to achieve the above requirements, the technical solution adopted by the present invention is: to provide a paper rolling system and paper rolling method for paper production, the paper rolling system and paper rolling method for paper production include a paper rolling drum and an upper conveyor belt component and a lower conveyor belt component arranged on the side of the paper rolling drum; the bottom of the paper rolling drum is fixed by a first support frame, the front end of the paper rolling drum is provided with a rotating motor, the output end of the rotating motor is connected to the center of the circle of the longitudinal section of the paper rolling drum, the side end surface of the rotating motor is connected to a horizontally arranged sensor bearing plate, and the rear end surface of the sensor bearing plate is provided with a horizontal light sensor; the center of the circle of the rear end longitudinal section of the paper rolling drum is connected to a horizontal bar slide and a horizontally arranged push-pull motor, the bar slide is provided with a push block sliding along the bar slide, and the output end of the push-pull motor is connected to the side end surface of the push block; the upper conveyor belt component is arranged above the lower conveyor belt component, and the upper conveyor belt component and the lower conveyor belt component are both fixed to the ground through a conveying component bracket.

[0008] A paper rolling method for paper production is provided, comprising the following steps:

[0009] S1: The paper is transported forward from between the upper conveyor belt and the lower conveyor belt. The upper conveyor belt and the lower conveyor belt are pressed tightly up and down so that only the thickness of one sheet of paper can pass through. This makes the paper transport more stable.

[0010] S2: After that, the paper passes under the auxiliary pressure roller and is then wound around the paper reel. The pressing connecting rod rotates around the pressing shaft to adjust the position of the auxiliary pressure roller. At the same time, a locking mechanism is provided on the pressing shaft to lock the pressing shaft after the adjustment is completed. The setting of the spring connecting rod allows the passing paper to have room for maneuver while limiting the downward pressure to avoid excessive pressure. The auxiliary pressure roller is a hollow lightweight plastic cylindrical structure.

[0011] S3: As the paper is wound around the paper roll, it becomes thicker and thicker. If the rotation frequency of the paper roll remains unchanged, the speed of the paper roll to collect the paper will become faster and will not be synchronized with the conveying speed of the upper conveyor belt component and the lower conveyor belt component. At this time, the conveying speed of the upper conveyor belt component and the lower conveyor belt component and the rotation frequency of the paper roll are adjusted so that the two satisfy the relationship in the following formula 1, so that the speeds of the two can be perfectly matched at all times:

[0012] Formula 1:

[0013] v = x(2πr+l);

[0014] in:

[0015] v: the moving speed of the unwound paper, unit: m / s;

[0016] x: The frequency of the paper roll rotation, unit: Hz, indicating the number of revolutions per second;

[0017] r: radius of the paper roll, unit: m;

[0018] l: total thickness of paper on the paper roll, unit: m;

[0019] In the above formula, the distance that the light emitting component is pushed out by the push-pull motor is the total thickness l of the paper on the paper roll, and the speed at which the upper conveyor belt component and the lower conveyor belt component convey the paper is the movement speed v of the unwound paper;

[0020] S4: During the process of paper winding on the paper reel, the light emitting component will be pushed outward by the push-pull motor, and the pushing distance meets the requirements of the above formula 1, so as to ensure that the light emitting component is always emitted at the edge of the outermost circle of paper wound on the paper reel and shines on the light sensor. If paper is crushed or mixed with foreign objects, the paper here will protrude outward, thereby blocking the light emitted by the light emitting component. At this time, the light sensor cannot receive the light. The light sensor is electrically connected to an alarm device. When the light sensor cannot receive the light, the alarm device will sound an alarm. The light sensor is electrically connected to the power switch of the overall system. When the light sensor cannot receive the light, the entire system is powered off, and the staff will solve the current problem.

[0021] The advantages of the paper production reeling system and paper reeling method are as follows:

[0022] The device and method can adjust the rotation speed of the paper roll and the conveying speed of the upper conveyor belt component and the lower conveyor belt component in real time according to the winding amount of the paper, so that the two are matched to make the storage process more stable; at the same time, the light emitting component and the light sensor can be used to detect in the first time when the paper is tilted or adhered to foreign objects.

[0035] v = x(2πr+l);

[0036] in:

[0037] v: the moving speed of the unwound paper, unit: m / s;

[0038] x: The frequency of the paper roll rotation, unit: Hz, indicating the number of revolutions per second;

[0039] r: radius of the paper roll, unit: m;

[0040] l: total thickness of paper on the paper roll, unit: m;

[0041] In the above formula, the distance that the light emitting component 16 is pushed out by the push-pull motor 14 is the total thickness l of the paper on the paper roll, and the speed at which the upper conveyor belt component 9 and the lower conveyor belt component 10 convey the paper is the movement speed v of the unwound paper.

[0042] According to one embodiment of the present application, the frequency of rotation of the paper reel 2 of the paper production reel system, the speed at which the upper conveyor belt component 9 and the lower conveyor belt component 10 convey the paper, and the distance by which the light emitting component 16 is pushed out by the push-pull motor 14 satisfy the following formula:

[0051] Considering that l represents the total thickness of the paper, it directly affects the contact area and friction resistance between the paper and the receiving shaft. eff There is a power function relationship between it and l, and x represents the rotation frequency of the storage shaft, which affects the winding speed of the paper and the heat generated by friction.

[0059] According to one embodiment of the present application, when the paper production reel system is used, Figures 1 to 2 As shown, the paper is conveyed forward between the upper conveyor belt component 9 and the lower conveyor belt component 10. The upper conveyor belt component 9 and the lower conveyor belt component 10 are pressed up and down so that only the thickness of a piece of paper can pass through, so that the paper conveying will be more stable. After that, the paper passes under the auxiliary pressure roller 4 and is then wound on the paper reel 2. The pressing connecting rod 6 can rotate around the pressing shaft 7 to adjust the position of the auxiliary pressure roller 4. At the same time, a locking mechanism is provided on the pressing shaft 7. After the adjustment is completed, the pressing shaft 7 is locked. The setting of the spring connecting rod 5 can leave room for maneuver for the passing paper while the downward pressure is limited to avoid excessive pressure. The auxiliary pressure roller 4 is a hollow lightweight plastic cylindrical structure. In the process of paper winding around the paper reel 2, the paper is wound about about 100 mm thick. If the rotation frequency of the paper reel 2 remains unchanged, the speed of paper collection of the paper reel 2 will become faster and will be out of sync with the conveying speed of the upper conveyor belt component 9 and the lower conveyor belt component 10. At this time, it is necessary to adjust the conveying speed of the upper conveyor belt component 9 and the lower conveyor belt component 10 and the paper reel 2. The rotation frequency of the rotation frequency is adjusted so that the two satisfy the relationship in the above formula, so as to ensure that the speeds of the two are perfectly matched at all times; at the same time, the light emitting component 16 will be pushed outward by the push-pull motor 14 in the process of paper winding on the paper reel 2, and the pushing distance satisfies the requirements in the above formula, so as to ensure that the light emitting component 16 is always emitted at the edge of the outermost circle of paper wound on the paper reel 2 and emitted onto the light sensor 12. If paper is crushed or mixed with foreign matter, the paper here will protrude outward, thereby blocking the light emitted by the light emitting component 16. At this time, the light sensor 12 cannot receive light. The light sensor 12 can be electrically connected to an alarm device. When the light sensor 12 cannot receive light, the alarm device will sound an alarm, and the light sensor 12 can be electrically connected to the power switch of the overall system. When the light sensor 12 cannot receive light, the overall power of the system is cut off, and the staff will solve the current problem. During the actual operation, one of the rotation frequency of the paper roll 2 or the transport speed of the upper conveyor belt component 9 and the lower conveyor belt component 10 can be set to be customized, so that the distance data item of the block 15 extending can be coordinated by adjusting the other item, so that these data items are always in a perfectly coordinated state.

[0060] According to one embodiment of the present application, the paper production paper rolling system and paper rolling method can adjust the rotation speed of the paper rolling drum 2 and the conveying speed of the upper conveyor belt component 9 and the lower conveyor belt component 10 in real time according to the winding amount of the paper, so that the two are matched to make the storage process more stable; at the same time, the light emitting component 16 and the light sensor 12 can be used to detect in the first time when the paper is tilted or adhered to foreign objects.

[0061] The above-mentioned embodiments only represent several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the claims.
