Description

Technical Field

[0001] The present disclosure relates to the technical field of papermaking equipment, and in particular to a paper roll width detection device. Background Art

[0002] Human life is inseparable from paper, including household paper, sanitary paper, and industrial paper. With demand growing year by year, the requirements for paper winding technology are becoming increasingly demanding. Rewinders are generally used for rewinding and slitting mica tapes, paper, and film, serving as a two-piece process. They are often used to slit wide rolls, playing an important role in subsequent re-slitting. They are specialized equipment for paper, mica tape, and film.

[0003] Currently, in the papermaking process, after the paper is unwound from the rewinder, a tape measure is generally used to measure the width of the paper roll. Usually, the deviation of the paper roll width is within 1-2mm. The measurement error of the tape measure is large and not accurate enough. In addition, manual measurement is greatly affected by the external environment and human operation errors. Utility Model Content

[0004] The present disclosure is proposed in view of the above problems. The present disclosure provides a paper roll width detection device that can automatically measure the paper roll width, saving manpower and reducing errors.

[0005] According to one aspect of the present disclosure, a paper roll width detection device is provided, including: a support arm, a movable arm and a scanning device, the movable arm having a first end and a second end, the first end being connected to the scanning device, one end of the support arm being fixedly connected to the ground, the support arm having a slide groove opened along the axial direction of the support arm, and the second end of the movable arm being slidably connected to the slide groove.

[0006] Compared to the prior art, the present invention provides a paper roll width detection device comprising a support arm, a movable arm, and a scanning device. The movable arm has a first end and a second end, the first end being connected to the scanning device, which can be used to scan the width of the paper roll exiting the rewinder. In this case, one end of the support arm is fixedly connected to the ground, and the support arm has an axially extending slot, with the second end of the movable arm slidably connected to the slot. Thus, the support arm is essentially fixed vertically to the ground, the movable arm is horizontal to the ground, and the second end of the movable arm is slidably connected to the support arm via the slot. Therefore, when the width of a paper roll exiting the rewinder needs to be measured, the movable arm can be used to drive the scanning device along the axial direction of the support arm. This allows for measuring the width of paper rolls of various sizes. Whether the paper roll is large or small, the position of the movable arm can be changed to measure the paper width at different heights of the paper roll, thereby calculating the average paper roll width. This reduces measurement errors, reduces labor waste and operational risks, and reduces the risk of defective paper rolls entering the market. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to make the purpose, technical solutions and advantages of the present disclosure more apparent, the following will describe in detail exemplary embodiments of the present disclosure with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments of the present disclosure, and it should be understood that the present disclosure is not limited to the exemplary embodiments described herein.

[0013] Human life is inseparable from paper, including household paper, sanitary paper, and industrial paper. With demand growing year by year, the requirements for paper winding technology are becoming increasingly demanding. Rewinders are generally used for rewinding and slitting mica tapes, paper, and film, serving as a two-piece process. They are often used to slit wide rolls, playing an important role in subsequent re-slitting. They are specialized equipment for paper, mica tape, and film.

[0014] Currently, in the papermaking process, after the paper is unwound from the rewinder, a tape measure is generally used to measure the width of the paper roll. Usually, the deviation of the paper roll width is within 1-2mm. The measurement error of the tape measure is large and not accurate enough. In addition, manual measurement is greatly affected by the external environment and human operation errors.

[0015] In response to the above problems, the embodiments of the present disclosure provide a paper roll width detection device that can automatically measure the paper roll width, saving manpower, reducing errors, and solving the problems of labor waste and large measurement errors in paper roll width detection in the prior art.

[0016] Figure 1FIG. 1 shows a schematic diagram of the structure of a paper roll width detection device provided by an embodiment of the present disclosure. Figure 1 As shown, the paper roll width detection device of the embodiment of the present disclosure includes: a support arm 100, a movable arm 200 and a scanning device 300, the movable arm 200 has a first end 200a and a second end 200b, the first end 200a is connected to the scanning device 300, one end of the support arm 100 is fixedly connected to the ground, the support arm 100 has a slide groove 110 opened along the axial direction of the support arm 100, and the second end 200b of the movable arm 200 is slidably connected to the slide groove 110.

[0017] It should be understood that the fixed connection of one end of the support arm 100 to the ground can be defined as the support arm 100 being vertically fixed to the ground. The second end 200b of the movable arm 200 being slidably connected to the slide 110 is equivalent to the movable arm 200 being arranged perpendicular to the support arm 100 and horizontal to the ground.

[0018] In specific implementations, the paper roll width detection device provided by the present disclosure can be used to measure the width of a paper roll exiting a rewinder. Once the paper roll is brought to the paper roll width detection device, the movable arm 200 can be used to drive the scanning device 300 to move along the axial direction of the support arm 100 to a desired position, where the scanning device 300 can scan the width of the paper roll exiting the rewinder. This allows for adaptability to a variety of paper roll specifications. Whether it's a large or small paper roll, the position of the movable arm 200 can be changed to measure paper width data at different roll heights, allowing for the calculation of the average roll width. This reduces measurement errors, minimizes labor waste, reduces operational risks, and prevents defective paper rolls from entering the market.

[0019] In one practicable manner, the paper roll width detection device provided by the present disclosure further includes a slider 400 , which is slidably engaged with the slide groove 110 , and the slider 400 is fixedly connected to the second end of the movable arm 200 .

[0020] During specific implementation, the slider 400 can be used to drive the movable arm 200 to move back and forth along the axial direction of the support arm 100 according to actual scanning needs, so that the movable arm 200 drives the scanning device 300 to move up and down, thereby measuring the paper width data at different paper roll heights by changing the position of the movable arm 200, and then further calculating the average value of the paper roll width to reduce the measurement error.

[0021] Illustratively, the paper roll width detection device of the embodiment of the present disclosure further includes a first hydraulic drive component, which is fixedly connected to the slider 400 and is used to drive the slider 400 to slide back and forth along the slide groove 110 .

[0022] In specific implementation, when the width of the paper roll coming out of the rewinder is measured and the scanning device 300 needs to be moved in the up and down directions, the first hydraulic drive component can be used to drive the slider 400 to slide along the slide groove 110. The slider 400 drives the movable arm 200 to slide along the slide groove 110, and then drives the scanning device 300 to slide in the up and down directions, and finally the scanning device 300 is moved to the required height to measure the width of the paper roll, thereby reducing labor waste and operational risks.

[0023] Illustratively, the first hydraulic drive assembly of the embodiment of the present disclosure includes a first hydraulic pump and a first hydraulic cylinder. The first hydraulic pump is used to drive the first hydraulic cylinder to slide along the slide groove, and the first hydraulic cylinder is fixedly connected to the slider.

[0024] In specific implementation, when it is necessary to move the scanning device 300 in the up and down directions, the first hydraulic pump can be used to drive the first hydraulic cylinder to move up and down, and the first hydraulic cylinder drives the slider 400 to slide up and down along the slide groove 110, thereby driving the scanning device 300 to slide in the up and down directions, and finally the scanning device 300 is moved to the required height to measure the width of the paper roll.

[0025] In an optional manner, the movable arm 200 of the embodiment of the present disclosure is a telescopic movable arm. Figure 2 FIG. 1 shows a schematic structural diagram of a retractable movable arm provided in an embodiment of the present disclosure. Figure 2 As shown, the telescopic movable arm provided in the embodiment of the present disclosure includes a telescopic rod 210 and a fixed rod 220 sleeved on the telescopic rod 210. The end of the telescopic rod 210 away from the support arm 100 is connected to the scanning device 300, and the end of the fixed rod 220 close to the support arm 100 is slidably connected to the support arm 100. It should be understood that the telescopic rod 210 and the fixed rod 220 are in the form of sleeves.

[0026] In specific implementations, when measuring the width of a paper roll exiting a rewinder, if the paper roll is located far away, the retractable rod 210 can be extended outward based on the actual position of the paper roll, bringing it closer to the paper roll before measuring the paper roll width. If the paper roll is located closer, the retractable rod 210 can be retracted inward based on the actual position of the paper roll, allowing it to adapt to the position of the paper roll before measuring the paper roll width. Thus, the telescopic movable arm in the form of a sleeve can meet the measurement requirements of different paper rolls, whether located far away or close, allowing for flexible paper roll width measurement.

[0027] In an optional embodiment, the paper roll width detection device of the embodiment of the present disclosure further includes a second hydraulic drive assembly, which is connected to the end of the telescopic rod 210 close to the support arm 100. It should be understood that the second hydraulic drive assembly is used to drive the telescopic rod 210 to move back and forth along the axial direction of the movable arm.

[0028] In specific implementations, if the paper roll is located far away, the second hydraulic drive assembly can be used to push the telescopic rod 210 outward based on the actual position of the paper roll, bringing the telescopic rod 210 closer to the paper roll before measuring the paper roll width. If the paper roll is located closer, the second hydraulic drive assembly can be used to retract the telescopic rod 210 inward based on the actual position of the paper roll, allowing the telescopic rod 210 to adjust to the position of the paper roll before measuring the paper roll width.

[0029] Exemplarily, the second hydraulic drive assembly of the embodiment of the present disclosure includes a second hydraulic pump and a second hydraulic cylinder, the second hydraulic cylinder is fixedly connected to one end of the telescopic rod 210 close to the support arm 100, and the second hydraulic pump is used to drive the telescopic rod 210 to move along the axial direction of the support arm 100.

[0030] In specific implementations, when the paper roll is located far away, the second hydraulic pump can be used to drive the second hydraulic cylinder outward based on the actual position of the paper roll, thereby pushing the telescopic rod 210 outward, bringing the telescopic rod 210 closer to the paper roll before measuring the paper roll width. When the paper roll is located closer, the second hydraulic pump can be used to drive the second hydraulic cylinder inward based on the actual position of the paper roll, retracting the telescopic rod 210 inward before measuring the paper roll width.

[0031] In one example, the scanning device 300 of the disclosed embodiment includes a paper roll data collector and a laser rangefinder. The paper roll data collector is used to collect raw data parameters of the paper roll, and the laser rangefinder is used to obtain the paper roll width. It is understood that the raw data parameters of the paper roll include the target width of the paper roll, the width deviation of the paper roll, and the paper roll ID.

[0032] In actual applications, there are many specifications for the width of the rewinder paper roll, including: 770mm, 787mm, 889mm, 1204mm, 1596mm, 1792mm, 2128mm, 2328mm, 2400mm, etc. The corresponding parameters can be set in the program in advance.

[0033] In specific implementation, the paper roll data collector can be used to collect the original data parameters of the paper roll (the target width of the paper roll, the width deviation of the paper roll, and the ID of the paper roll), and the laser rangefinder can be used to measure the actual width of the paper roll.

[0034] It should be understood that the scanning device 300 scans the paper roll width data and can obtain the paper roll width data at the highest position and the paper roll width data at 30° on both sides of the highest position, calculate the average value, and then use this value to compare with the width parameters during paper roll production to determine the error deviation of the paper roll width.

[0035] In practice, the paper rolls produced by the rewinder are divided into customer rolls and flat rolls. Customer rolls are shipped directly to customers, while flat rolls are sent to post-processing for further slitting. Based on the paper roll's properties, customer rolls with severe deviations are recorded by the inspection system and automatically reclassified from Grade A to Grade H. These grades cannot be shipped directly and require rework. Flat rolls are then recorded with their IDs and centrally cut in post-processing. Once the classification is corrected, they are scheduled for the next process step.

[0036] In one practicable manner, the paper roll width detection device of the embodiment of the present disclosure further includes a controller, the scanning device is connected to the controller signal, and the first hydraulic drive component and the second hydraulic drive component are also connected to the controller signal.

[0037] In an optional manner, the paper roll width detection device of the embodiment of the present disclosure further includes an alarm, and the alarm is electrically connected to the controller.

[0038] During specific implementation, the scanning device 300 can be used to scan the width of the paper roll, and then a paper roll width deviation signal is sent to the controller. If the scanning device 300 detects that the deviation between the actual width of the paper roll and the target width reaches 2mm to 5mm, the controller can control the alarm to sound an alarm, the alarm indicator light will light up, and the operation will stop. The alarm sound will prompt the on-site staff to check whether the paper roll label is incorrectly affixed. After confirming the cause of the deviation, manual reset will be performed and the operation will be restarted, further ensuring the safety of the process system.

[0039] Each operation in the above method disclosed in the embodiment of the present disclosure can be completed by an integrated logic circuit of the hardware in the processor or an instruction in the form of software. The above processor can be a general-purpose processor, a digital signal processor (DSP), an ASIC, a field-programmable gate array (FPGA) or other programmable logic device, a discrete gate or transistor logic device, a discrete hardware component. The general-purpose processor can be a microprocessor or the processor can also be any conventional processor, etc. The steps of the method disclosed in the embodiment of the present disclosure can be directly embodied as being executed by a hardware decoding processor, or being executed by a combination of hardware and software modules in the decoding processor. The software module can be located in a memory, such as a random access memory, a flash memory, a read-only memory, a programmable read-only memory or an electrically erasable programmable memory, a register, or other mature storage media in the art. The processor reads the information in the memory and completes the above operations in combination with its hardware.

[0040] In actual applications, the control program can be stored in a computer device in advance, and then the computer device or controller can be used to send a start instruction or a stop instruction to the first hydraulic drive component, the second hydraulic drive component and the scanning device. Therefore, when the position of the scanning device needs to be moved, the start and stop of the first hydraulic drive component, the second hydraulic drive component and the scanning device can be directly controlled by the controller to realize the automatic measurement of the paper roll width.
