Description

Technical Field

[0001] This application relates to the field of absorbent paper core production technology, and in particular to an absorbent paper core cutting and detection device that can avoid paper core adhesion and obstruction. Background Technology

[0002] As a functional structural component with high absorbency, absorbent paper cores are widely used in fields such as baby care products, medical consumables, and household cleaning products. Their product quality directly determines the user experience and functional reliability of downstream products. In particular, residues such as raw material residues adhering to the production process, oil stains formed by equipment lubricating oil leakage, and discolored impurities mixed in during fiber processing can not only damage the appearance consistency of the paper core, but also affect the water absorption rate and cause hygiene hazards. For scenarios with strict hygiene requirements such as baby care and medical care, it may even lead to the scrapping of downstream products. Therefore, extremely high requirements are placed on stain detection during the production process of absorbent paper cores. The existing technology has the following problems: At present, the stain detection process in the production process of absorbent paper cores still generally relies on the traditional method of manual visual inspection. Since absorbent paper cores are mostly light-colored bases such as white and light beige, manual inspection is prone to missed detection due to visual fatigue, which cannot guarantee the consistency of product quality. Utility Model Content

[0004] The technical solution of this application is implemented as follows: This application provides a water-absorbing paper core slitting and detection device that can avoid paper core adhesion and obstruction, including a frame, a slitting machine fixedly installed at the top of the frame, a control cabinet provided at the front of the frame, and the slitting machine and the control cabinet being electrically connected; it also includes a detection component, which is fixedly installed at the top of the slitting machine and spans the table of the slitting machine, and the detection component is electrically connected to the control cabinet; The detection component includes a mounting plate, which is provided in two sets and fixedly installed on the left and right sides of the top of the slitting machine. A connecting plate is fixedly installed on the front end of the inner side of the two sets of mounting plates. The connecting plate spans the table of the slitting machine. The top of the connecting plate has an array of through-holes. A separator blade is provided on the connecting plate at the bottom position corresponding to the mounting hole. A bolt is embedded in the mounting hole. After the bolt passes through the mounting hole, it is screwed into the top of the separator blade and detachably fixed to the bottom of the connecting plate. The separator blade is embedded in the gap between two sets of adjacent absorbent paper cores cut by the slitting machine. Two sets of mounting plates are embedded with camera detection components at their top ends. The camera detection components span the slitting machine table and are electrically connected to the control cabinet. The camera detection components are used to detect stains in the absorbent paper core production process.

[0005] In one embodiment, a transmission lamp is fixedly installed at the bottom front end of the slitting machine.

[0006] In one embodiment, the camera detection component includes an embedded plate, two sets of which are respectively embedded in the top and bottom ends of the two sets of mounting plates. An installation beam is fixedly connected to the inner side of the two sets of embedded plates. The installation beam spans the slitting machine table. An industrial camera is fixedly installed at the bottom center of the installation beam. The industrial camera is electrically connected to the control cabinet.

[0007] In one embodiment, a supplementary light is fixedly installed at the bottom of the mounting beam, away from the installation position of the industrial camera, and the supplementary light is electrically connected to the control cabinet.

[0008] In one embodiment, the separator includes a mounting bracket with a threaded hole at the top.

[0010] In one embodiment, the number of the separating blades corresponds one-to-one with the number of cutting passes of the slitting machine, so as to separate each pair of adjacent absorbent cores after slitting.

[0011] The advantages or beneficial effects of the above technical solutions include at least the following: This application discloses a water-absorbing paper core slitting and inspection device that avoids paper core adhesion and obstruction. By using a transparent conveyor belt of the slitting machine in conjunction with a bottom transmission lamp, the light penetration characteristics are utilized to create a clear light and shadow contrast between the surface and hidden stains inside the blank, which can reduce eye fatigue and help people perform better initial screening with the naked eye. Subsequently, the combination of a camera inspection component and a supplementary light lamp is used to stabilize the light source and eliminate ambient light interference. Combined with the high-frequency and precise shooting of an industrial camera, it can replace the naked eye to complete the surface inspection of the paper core after slitting, which can significantly reduce the risk of missed inspection due to visual fatigue and improve the consistency of product quality. Meanwhile, by setting up a separator blade, it can be ensured that the industrial camera can clearly capture the stains on the surface of the paper core, avoiding blind spots caused by obstruction and further improving the stain recognition accuracy; in addition, relying on the automated linkage control of the control cabinet can significantly improve production inspection efficiency and reduce reliance on manual labor. In summary, this application can improve the reliability of product quality in downstream maternal and infant, medical and other demanding hygiene scenarios, reduce the risk of downstream product scrapping due to stain residue, and improve economic benefits.

[0020] Reference Figure 1 A water-absorbing paper core slitting and detection device that can avoid paper core sticking and obstruction includes a frame 1 and a detection component 4. The frame 1 serves as the supporting frame of the device and provides a stable installation reference for the slitting machine 2.

[0021] A slitting machine 2 is fixedly installed at the top of the frame 1. The slitting machine 2 is used to cut the absorbent paper core into single finished products according to the preset length. It is electrically connected to the control cabinet 3 and can receive instructions from the control cabinet to adjust the cutting speed and cutting length to meet the production needs of absorbent paper cores of different specifications.

[0022] The front end of the frame 1 is equipped with a control cabinet 3. The slitting machine 2 is electrically connected to the control cabinet 3. The control cabinet 3 is an automation control and signal processing component. It can control the operating parameters of the slitting machine 2 to ensure the automation of the cutting process. It can receive the stain detection signal transmitted by the detection component 4, analyze and judge the signal to identify whether there is a stain and the location of the stain. It can control the start, stop and brightness of the transmission lamp 5 and the supplementary light 464 to provide a stable light source for the detection process. In this embodiment, the control cabinet 3 adopts the Panasonic AFPX series, which can centrally control the slitting machine 2, the receiving and detection component 4, and the transmission lamp 5. It should be noted that the Panasonic AFPX series control cabinet 3 is a mature existing technology in the industrial field. The hardware structure, basic control logic, and supporting software of the above-mentioned control unit have been widely used in automated production lines such as the slitting machine 2 and the detection equipment. The relevant technical principles, installation methods, and debugging procedures are all supported by publicly available technical manuals and industry application cases. Therefore, this application will not elaborate on its specific hardware structure and basic control principles.

[0023] The detection component 4 is used to detect the absorbent paper cores that have been cut into single-piece finished products by the slitting machine 2.

[0024] Among them, the bottom front end of the slitting machine 2 is fixedly installed with a transmission lamp 5. The transmission lamp 5 can illuminate the uncut paper core blank through the transmission light, so that the stains and the surface of the blank form a clear light and shadow contrast, which makes it convenient for the operator to conduct a preliminary visual inspection before the absorbent paper core enters the cutting. It should be noted that when installing the transmission lamp 5, the conveyor belt of the slitting machine 2 should be made of transparent material to ensure that the transmission lamp 5 can illuminate the uncut paper core blank.

[0025] In one embodiment, reference is made to Figures 2-4 The detection component 4 is fixedly installed on the top of the slitting machine 2 and spans the table of the slitting machine 2. The detection component 4 is electrically connected to the control cabinet 3. The detection component 4 includes a mounting plate 41. Two sets of mounting plates 41 are fixedly installed on the left and right sides of the top of the slitting machine 2, respectively. The mounting plate 41 serves as a support component, providing a fixed installation position for the connecting plate 42 and the camera detection component 46.

[0026] Two sets of mounting plates 41 are fixedly mounted with connecting plates 42 on their inner front ends. The connecting plates 42 span the table of the slitting machine 2. The top of the connecting plates 42 is provided with an array of mounting holes 43. The connecting plates 42 are used to support the installation of the separator blades 44 and to install multiple sets of separator blades 44 through the mounting holes 43 on the top array, so as to meet the multi-cutting requirements of the slitting machine 2.

[0027] A separator blade 44 is provided at the bottom of the mounting hole 43 on the connecting plate 42. A bolt 45 is embedded in the mounting hole 43. After the bolt 45 passes through the mounting hole 43, it is screwed into the top of the separator blade 44, and the separator blade 44 is detachably fixed to the bottom of the connecting plate 42. The bolt 45 is used to cooperate with the mounting hole 43 to achieve the detachable fixation of the separator blade 44.

[0028] The separator 44 is embedded in the gap between two sets of adjacent absorbent paper cores cut by the slitting machine 2. When the separator 44 is embedded in the gap between the two sets of adjacent absorbent paper cores, it can physically separate the paper cores that are attached, avoid the paper cores overlapping and blocking the stains, and provide a clear detection field of view for the camera detection component 46.

[0029] The number of separator blades 44 corresponds one-to-one with the number of cutting passes of the slitting machine 2, so as to separate each pair of adjacent absorbent paper cores after slitting. Each additional cut of the slitting machine 2 will simultaneously form a pair of adjacent absorbent paper cores. The one-to-one corresponding separator blades 44 can be precisely embedded in the gap between each pair of paper cores, completely separating the paper cores that may have been stuck together due to conveying and squeezing, and preventing stains from being hidden in a certain gap due to not being separated and the paper cores covering each other. Meanwhile, the design can be adapted to the production process of the slitting machine 2. Each time the slitting machine 2 completes a multi-pass cut, the corresponding number of separating blades 44 can simultaneously complete the separation of all adjacent paper cores without additional adjustments or multiple operations.

[0030] Two sets of mounting plates 41 are embedded with camera detection components 46 at their top ends. The camera detection components 46 span the table of the slitting machine 2 and are electrically connected to the control cabinet 3. The camera detection components 46 are used to detect stains in the absorbent paper core production process. The camera detection components 46 can capture surface images of the paper core after slitting and transmit the image signals to the control cabinet 3. The control cabinet 3 analyzes and determines whether stains exist, replacing manual visual inspection and improving detection efficiency and accuracy.

[0031] In one embodiment, reference is made to Figure 5 The camera detection component 46 includes an embedded plate 461. Two sets of embedded plates 461 are provided and are respectively embedded in the top and bottom ends of the two sets of mounting plates 41. The embedded plate 461 is used for installation and support. It is mechanically fitted and firmly connected to the mounting plate 41, which can fix the relative position of the entire camera detection component and the table of the slitting machine 2, and avoid the detection field of view shift due to equipment vibration.

[0032] Two sets of embedded plates 461 are fixedly connected to the inner side of the mounting beam 462. The mounting beam 462 spans across the two tables of the slitting machine and provides a mounting position for the industrial camera 463 and the supplementary light 464. At the same time, the design of spanning across the two tables of the slitting machine allows the industrial camera 463 to face the conveying path of the slitting absorbent paper cores, ensuring that the lens covers all the paper cores to be inspected.

[0033] An industrial camera 463 is fixedly installed at the bottom center of the mounting beam 462. The industrial camera 463 is electrically connected to the control cabinet 3. When working, the lens of the industrial camera 463 is facing the surface of the cut absorbent paper core. After receiving the shooting command sent by the control cabinet 3, it takes a picture. The captured image signal is transmitted to the control cabinet 3, and the control cabinet 3 analyzes and judges the signal, replacing manual visual identification of stains and greatly improving detection efficiency and accuracy. It should be noted that the industrial camera 463 is an existing component, so its structure and principle will not be described in detail.

[0034] Among them, a supplementary light 464 is fixedly installed at the bottom of the mounting beam 462, avoiding the mounting position of the industrial camera 463. The supplementary light 464 is electrically connected to the control cabinet 3. The supplementary light 464 is used to provide a stable and uniform auxiliary light source for the detection process of the industrial camera 463, to make up for the instability of the natural light in the workshop, to ensure uniform illumination on the paper core surface, to make the stains and the paper core substrate form a clear brightness contrast, and to improve the recognizability of stains in the image. The supplementary light 464 is connected to the control cabinet 3 via an electrical signal. The control cabinet 3 can synchronously control the opening and closing timing and lighting duration of the supplementary light 464 according to the cutting speed of the slitting machine 2 and the shooting frequency of the industrial camera 463.

[0035] In one embodiment, reference is made to Figures 6-7 The separator blade 44 includes a mounting bracket 441. The top of the mounting bracket 441 is provided with a threaded hole 442. The bolt 45 passes through the mounting hole 43 and is screwed into the threaded hole 442, thereby detachably fixing the mounting bracket 441 to the bottom of the connecting plate 42. The mounting bracket 441 is used for support and connection and provides an installation position for the blade 444.

[0036] Meanwhile, the detachable connection between the bolt 45 and the threaded hole 442 allows for adjustment of the position of the mounting bracket 441 or replacement of the separator blade 44 of different sizes according to the specifications of the absorbent paper core, thereby improving the adaptability of the device to products of various specifications.

[0037] The mounting bracket 441 has an embedding groove 443 at its bottom. The embedding groove 443 is used to provide mounting positioning for the blade 444. The shape and size of the groove limit the lateral and longitudinal displacement of the blade 444, ensuring that the blade 444 maintains a preset angle when separating the paper core. This prevents the paper core from running off-center or being incompletely separated due to the blade 444 being skewed. At the same time, the embedding groove 443 can protect the root of the blade 444, reducing the risk of bending or breaking of the blade 444 when it is under force.

[0038] A blade 444 is embedded in the groove 443. The blade 444 is embedded in the gap between two sets of adjacent absorbent paper cores cut by the slitting machine 2. The blade 444 separates the paper cores that may have been attached by physical separation, avoiding the paper cores from blocking the stains in the gaps, and ensuring that the industrial camera 463 of the camera detection component 46 can clearly capture the surface condition of the side of the paper core and the gaps. In this embodiment, the blade 444 has a semi-circular structure, and its overall thickness matches the cutting blade on the slitting machine 2 and does not exceed the gap width of the adjacent absorbent paper core, ensuring that it can be smoothly embedded in the gap without squeezing the paper core. The semi-circular blade 444 can better fit the outer surface of the paper core and separate the fitted paper core, avoiding obscuring the stains in the gap and ensuring a clear detection field of the industrial camera 463. The embedding groove 443 is a rectangular straight groove that matches the semi-circular flat top of the blade 444. The groove width is the same as the thickness of the flat top of the blade, ensuring that the flat top of the blade 444 can be smoothly embedded into the groove. At the same time, a positioning threaded hole is transversely opened on the side wall of the mounting bracket 441 corresponding to the position of the embedding groove 443. After the positioning bolt is screwed into the side wall of the mounting bracket 441 through the positioning threaded hole, its screwed end will press against the side of the flat top of the blade 444. Through the axial tightening force of the positioning bolt, the blade is fixed in the embedding groove 443.

[0039] A rubber pad is provided between the blade 444 and the embedding groove 443. The rubber pad is used to fill the installation gap between the blade 444 and the embedding groove 443, which can prevent the blade 444 from becoming loose due to vibration when separating the paper core. At the same time, it buffers the contact force between the blade 444 and the embedding groove 443, preventing the embedding groove from scratching the surface of the blade 444 and extending the service life of the blade 444.

[0040] Working principle: First, the absorbent paper core blank will enter the transparent material conveyor belt of the slitting machine 2. Before the conveyor belt transports it to the cutting area of ​​the slitting machine 2 for cutting, the transmission lamp 5 at the bottom front end of the slitting machine 2 has been turned on in advance. The light of the transmission lamp 5 can penetrate the transparent conveyor belt and directly illuminate the uncut paper core blank on the conveyor belt, so that the hidden stains on the surface and inside of the blank and the blank base form a clear light and shadow contrast, which makes it convenient for the operator to perform preliminary visual inspection of the blank and complete the initial inspection. Subsequently, the paper core blanks that have undergone initial inspection are continuously conveyed by the transparent conveyor belt to the cutting area of ​​the slitting machine 2. The slitting machine 2 receives instructions from the control cabinet 3 and cuts the continuous paper core blanks into single finished products according to the preset length using its own cutting blade. After slitting, the individual absorbent paper cores continue to be conveyed by the transparent conveyor belt and enter the detection range of the detection component 4. At this time, the separator blades 44, which correspond one-to-one with the number of cuts of the slitting machine 2, are fixed to the bottom of the connecting plate 42 by bolts 45. The semi-circular blades 444 are precisely embedded in the gaps between each pair of adjacent absorbent paper cores, physically separating the paper cores that have just been cut by the slitting machine 2, and preventing the stains in the gaps from being covered. At the same time, the control cabinet 3 simultaneously starts the camera detection component 46 and the supplementary light 464. The supplementary light 464 provides a stable and uniform auxiliary light source to eliminate the influence of fluctuations in natural light in the workshop on the detection. The industrial camera 463 is aimed at the separated paper cores on the conveyor belt and takes pictures of the surface and gaps of the paper cores at a frequency adapted to the cutting speed of the slitting machine 2, and transmits the image signals to the control cabinet 3 in real time. Control cabinet 3 analyzes and judges the received image signals to identify whether there are stains and the location of the stains. If a defective product is found, it can trigger further processing instructions.
