Description

Technical Field

[0001] This application relates to the field of paper roll detection technology, such as a paper roll rewinding detection device and its control method and storage medium. Background Technology

[0002] Paper rolls are made from paper produced by papermaking machines and cut and rolled by rewinding machines to meet national standards or user requirements for width and diameter. However, because paper rolls are rolled inside the paper, quality inspection is more troublesome. Relying on human visual inspection is cumbersome, inefficient, and incomplete.

[0003] There is a paper roll inspection device in the related technology that uses unwinding and rewinding to complete the inspection of paper rolls. During the inspection process, the unqualified parts of the paper roll are cut off. The unqualified parts of the paper roll are removed by going through a series of processes such as stopping the machine, cutting the paper, and splicing the paper. However, the removal of waste requires many cumbersome processes, and the paper roll is repeatedly unwinded and rewound, which is time-consuming and has low waste removal efficiency.

[0004] Therefore, it is evident that simplifying the waste removal process, shortening its duration, and improving inspection efficiency are technical problems that urgently need to be solved by those skilled in the art.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0006] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0007] This disclosure provides a paper roll rewinding detection device, its control method, and a storage medium, which can efficiently and quickly remove defective parts from the paper roll and quickly resume operation without replacing the roll or rewinding and removing waste, reducing the complexity of the process, saving time, and improving quality inspection efficiency.

[0008] In some embodiments, a paper roll rewinding detection device includes: a machine base, a detection component, a pressing structure, a paper roll processing structure, and a controller component. The machine base has an unwinding roller and a rewinding roller at both ends of its upper surface, and a recessed receiving space is also provided on the machine base. Receiving cavities are formed on the opposite side walls of the receiving space at their opening positions. The detection component is positioned corresponding to the receiving space and is used to detect the quality information of both sides of the paper roll in the opening area of ​​the receiving space, and to determine the horizontal length of the defective portion of the paper roll if the paper roll's quality is unqualified. The pressing structure is movably disposed within the receiving space, and when the paper roll's quality is unqualified, the pressing structure is used to move the defective portion of the paper roll into the receiving space. The paper roll processing structure includes a shearing component. The paper roll has a shearing section and a gluing section, which are movably disposed within the receiving cavity. The gluing section is disposed on the shearing section, and the gluing section and the shearing section are aligned at the end facing the receiving space. When the pressing structure moves the defective part of the paper roll into the receiving space, the shearing section is used to cut the defective part of the paper roll, and the gluing section simultaneously bonds the cut paper roll. The controller assembly is connected to the detection assembly, the pressing structure, the shearing section, and the gluing section. The controller assembly is used to control the pressing structure to move the defective part of the paper roll into the receiving space based on the detection result of the detection assembly and when the paper roll is defective, and to control the shearing section to move the defective part of the paper roll into the receiving space.

[0009] The defective parts of the paper rolls are cut off, and the bonding of the cut paper rolls is also controlled.

[0010] In some embodiments, a control method for a paper roll rewinding detection device includes:

[0011] Obtain mass information of both sides of the paper roll located in the area of ​​the opening of the containment space;

[0012] In the case of a paper roll that is not up to standard, determine the horizontal length of the defective portion of the paper roll and control the movement of the pressing structure to move above the defective portion of the paper roll.

[0013] Based on the horizontal length of the defective portion of the paper roll, the pressing structure is controlled to press the defective portion of the paper roll into the receiving space by a set length, wherein the set length is half of the horizontal length of the defective portion of the paper roll.

[0014] Based on the movement of the pressing structure, the paper roll processing structure is controlled to cut and bond the defective parts of the paper roll located in the receiving space.

[0015] The paper roll backwinding detection device, control method, and storage medium provided in this disclosure can achieve the following technical effects:

[0016] It can perform comprehensive inspection of paper rolls from unwinding to rewinding, and implement a positioning and rewinding function to remove defective parts if the paper roll is of substandard quality. This involves controlling the downward pressing structure to move the defective parts of the paper roll into the receiving space, then controlling the shearing part to cut the defective parts of the paper roll in the receiving space, and controlling the gluing part to bond the cut paper roll. This allows for efficient and quick removal of defective parts from the paper roll and rapid reconnection without the need to change rolls or rewind and remove defective parts, reducing the complexity of the process, saving time, and improving inspection efficiency.

[0041] Combination Figure 1As shown in Figure 5, this embodiment of the present disclosure provides a paper roll rewinding detection device, including: a machine base 100, a detection component 400, a pressing structure 500, a paper roll processing structure 600, and a controller component 700. The machine base 100 has an unwinding roller 200 and a rewinding roller 300 respectively disposed at both ends of its upper surface. The machine base 100 also has a downwardly recessed receiving space 101, and accommodating cavities 102 are formed on the opposite side walls of the receiving space 101 at their opening positions. The detection component 400 is correspondingly disposed at the position of the receiving space 101, used to detect the quality information of both sides of the paper roll in the opening area of ​​the receiving space 101, and to determine the horizontal length of the defective portion of the paper roll if the paper roll quality is unqualified. The pressing structure 500 is movably disposed within the receiving space 101, and when the paper roll quality is unqualified, the pressing structure 500 is movably used to move the defective portion of the paper roll into the receiving space 101. The paper roll processing structure 600... The paper roll receiving structure 600 includes a shearing part 601 and an adhesive part 602. The shearing part 601 is movably disposed within the receiving cavity 102, and the adhesive part 602 is disposed on the shearing part 601, with the adhesive part 602 aligned with the end of the shearing part 601 facing into the receiving space 101. When the pressing structure 500 moves the defective portion of the paper roll into the receiving space 101, the shearing part 601 cuts the defective portion of the paper roll, while the adhesive part 602 adheres the cut paper roll. The controller assembly 700 is connected to the detection assembly 400, the pressing structure 500, the shearing part 601, and the adhesive part 602. The controller assembly 700 controls the pressing structure 602 based on the detection result of the detection assembly 400, and when the paper roll is defective.

[0042] The mechanism 500 moves the defective portion of the paper roll into the receiving space 101, and controls the shearing unit 601 to move the defective portion of the paper roll into the receiving space 101.

[0043] The defective parts of the paper roll in section 101 are cut off, and the adhesive part 602 is also controlled to bond the cut paper roll.

[0044] The apparatus for paper roll rewinding detection provided in this embodiment can perform comprehensive inspection of the paper roll during the unwinding to rewinding process. In the case of unqualified paper roll quality, a positioning rewinding and waste removal function is implemented. Specifically, the pressing structure 500 is controlled to move the unqualified part of the paper roll into the receiving space 101. Then, the shearing part 601 is controlled to cut the unqualified part of the paper roll located in the receiving space 101, and the gluing part 602 is controlled to bond the cut paper roll. This allows for efficient and quick removal of unqualified parts from the paper roll and rapid reconnection without the need to replace the roll or rewind and remove waste, reducing the complexity of the process, saving time, and improving inspection efficiency.

[0045] Optionally, the width of the table surface on the machine 100 is greater than or equal to the width of the paper roll. This allows the paper roll to be fed more efficiently on the machine 100, ensuring the neatness of the paper roll feeding and facilitating subsequent accurate inspection and waste removal operations.

[0046] Optionally, the horizontal length of the defective portion of the paper roll is in the same direction as the conveying direction of the machine 100, and the horizontal length of the defective portion of the paper roll is less than or equal to the horizontal length of the opening of the receiving space 101. In this way, the quality of the paper roll located in the opening area of ​​the receiving space 101 can be comprehensively inspected, ensuring the comprehensiveness of the inspection.

[0047] Optionally, the receiving space 101 has a U-shaped structure, and the pressing structure 500 is located on the vertical midline of the receiving space 101. In this way, the U-shaped receiving space 101 can receive the cut paper rolls and collect and store them centrally. The pressing structure 500 is located on the vertical midline of the receiving space 101, which facilitates more precise movement of the defective parts of the paper rolls into the receiving space 101, avoiding cutting the qualified parts of the paper rolls, ensuring the accuracy of cutting, and avoiding waste of paper rolls.

[0048] Optionally, both the unwind roll 200 and the take-up roll 300 are driven by forward and reverse motors. This makes the rotation of the unwind roll 200 and the take-up roll 300 more flexible, allowing for flexible control of their direction of rotation according to the waste removal operation requirements, so as to stably and accurately remove waste from the paper roll.

[0049] Optionally, the paper roll processing structures 600 are arranged in pairs, with one paper roll processing structure 600 installed in a receiving cavity 102 opened on one side wall of the receiving space 101, and the other paper roll processing structure 600 installed in a receiving cavity 102 opened on the other side wall of the receiving space 101. Each paper roll processing structure 600 includes a cutting part 601 and a gluing part 602. In this way, the paired cutting part 601 and gluing part 602 can better process the paper roll, ensuring more stable and neat cutting and gluing of the paper roll.

[0050] Optionally, the cutting part 601 is installed in the receiving cavity 102 via an electric push rod. The cutting part 601 is a cutting blade, with the tip of the cutting blade facing the receiving space 101. The receiving space 101 moves in opposite directions relative to the cutting blades in the receiving cavity 102 on both sides to cut the paper roll. The gluing part 602 is a pressing plate with tape or glue attached. In this way, using the cutting blades moving in opposite directions to cut the paper roll helps to more accurately position and cut the paper roll, ensuring the stability and accuracy of the cutting. The gluing part 602, being a pressing plate with tape or glue attached, simplifies the bonding method and helps to complete the bonding quickly.

[0051] Optionally, the shearing part 601 and the gluing part 602 are detachably connected. Preferably, the gluing part 602 is bolted to the shearing part 601, and the adhesive end of the gluing part 602 is aligned with the tip of the shearing part 601. This facilitates independent disassembly, maintenance, or replacement, and ensures the stability of the connection. The alignment of the adhesive end of the gluing part 602 with the tip of the shearing part 601 ensures that cutting and bonding are performed simultaneously, allowing for timely bonding after cutting and reducing the impact on the paper roll conveying process.

[0052] Optionally, when the paired paper roll processing structures 600 are removed from the receiving cavity 102, the sum of the areas of the paired paper roll processing structures 600 is equal to the area of ​​the opening of the receiving space 101. In this way, the opening of the receiving space 101 can be blocked by the paired paper roll processing structures 600, and the paper roll processing structures 600 can be incorporated into the machine 100, which helps to better transport the paper rolls.

[0053] Optionally, the detection components 400 are arranged in pairs, with one of the detection components 400 disposed on the upper part of the receiving space 101.

[0054] A square, used to detect the quality information of the upper side of the paper roll located in the opening area of ​​the receiving space 101, and another detection component.

[0055] The 400 is provided with an inner wall of the receiving space 101 for detecting the quality information of the lower side of the paper roll located in the opening area of ​​the receiving space 101, and for determining the horizontal length of the defective portion on the upper and lower sides of the paper roll when the paper roll is of substandard quality. This allows for efficient and rapid independent detection of both sides of the paper roll, ensuring the reliability of the detection results, avoiding omissions, and guaranteeing the quality of the paper roll. Furthermore, determining the horizontal length of the defective portion on the upper and lower sides of the paper roll when the paper roll is of substandard quality facilitates subsequent waste removal operations and ensures the accuracy of waste removal.

[0056] Optionally, each detection component 400 includes a first detection unit 401 and a second detection unit 402, which are arranged adjacent to and connected to each other. The first detection unit 401 is used to detect the quality information of the paper roll located in the opening area of ​​the receiving space 101, and the second detection unit 402 is used to determine the horizontal length of the defective portion of the paper roll when the paper roll is of substandard quality. In this way, while ensuring comprehensive and accurate detection of the paper roll, the extent of dirt on the paper roll can be more accurately determined, so as to accurately cut and discard the paper roll in the subsequent process, avoiding cutting off the qualified portion of the paper roll, ensuring the accuracy of cutting and avoiding waste of the paper roll.

[0057] Understandably, the first detection unit 401 is an image recognition camera, and the second detection unit 402 is an infrared ranging sensor. Both the image recognition camera and the infrared ranging sensor are existing technologies, and their specific structures and detection methods will not be described in detail here.

[0058] Optionally, the pressing structure 500 includes a mounting frame 501 and a pressing roller 502. The mounting frame 501 is a telescopic rod structure and is vertically arranged on one side inside the receiving space 101; the pressing roller 502 is a telescopic rod structure, and the pressing roller 502 is vertically connected to the top of the mounting frame 501, and the pressing roller 502 is arranged facing the receiving space 101. This design allows for greater flexibility in the structure of both the mounting frame 501 and the lower pressure roller 502. The position of the lower pressure roller 502 can be adjusted using a telescopic method according to usage requirements. When the lower pressure roller 502 is needed to press down the paper roll, it can be quickly adjusted using the mounting frame 501 to position it directly above the paper roll, ensuring that the lower pressure roller 502 can stably and neatly press the paper roll into the receiving space 101. When the lower pressure roller 502 is not needed, it can be retracted to ensure that both the mounting frame 501 and the lower pressure roller 502 are completely within the receiving space 101, thus avoiding interference with the paper roll conveying and the detection component 400's detection of the paper roll.

[0059] Understandably, both the mounting frame 501 and the lower pressure roller 502 use electric telescopic rods. Electric telescopic rods are existing technology, and their specific structure will not be described in detail here.

[0060] Optionally, the mounting frame 501 is connected to both the detection component 400 and the controller component 700. The controller component 700 controls the extension and retraction of the mounting frame 501 based on the horizontal length of the defective portion of the paper roll. This ensures that the pressure roller 502 can stably and neatly press the paper roll into the receiving space 101, and also more accurately presses the dirty portion of the paper roll into the receiving space 101, so that the paper roll can be accurately cut and discarded later, avoiding cutting the qualified portion of the paper roll, ensuring the accuracy of cutting while avoiding waste of the paper roll.

[0061] Optionally, the maximum telescopic beam of the mounting frame 501 is greater than or equal to the height of the receiving space 101, and the maximum telescopic amount of the lower pressure roller 502 is the same as the width of the upper table of the machine base 100. In this way, the telescopic movement of the mounting frame 501 can raise the lower pressure roller 502 above the paper roll, and the maximum telescopic amount of the lower pressure roller 502 is the same as the width of the upper table of the machine base 100, so that the lower pressure roller 502 can better press down on the paper roll, ensuring that the paper roll can move neatly downward into the receiving space 101 under the action of the lower pressure roller 502, and also ensuring the neatness of subsequent cutting.

[0062] Optionally, the controller assembly 700 controls the mounting frame 501 and the lower pressure roller 502 in the following order: the extension and retraction of the mounting frame 501 is completed before the extension and retraction of the lower pressure roller 502 is controlled. This streamlines the control sequence, allowing for the methodical adjustment of the lower pressure roller 502's position even when the paper roll quality is substandard, ensuring stable paper roll loading using the lower pressure roller 502.

[0063] The substandard parts are pressed down into the containment space 101.

[0064] Optionally, the center line of the unwinding roller 200, the take-up roller 300, and the upper surface of the machine base 100 is the same straight line. This ensures the consistency of the paper roll's position during the conveying process, prevents the paper roll from shifting position, and allows the paper roll to always move along a straight line.

[0065] like Figure 6 As shown in Figure 7, optionally, the paper roll rewinding detection device further includes a paper roll strength detection structure 800. The paper roll strength detection structure 800 is disposed between the machine base 100 and the winding roll 300, and located on the upper side of the paper roll, for detecting the strength at the glued joint of the paper roll. This allows for the detection of the glued joint strength at the paper roll's glued joint, preventing situations where unstable glued joints affect subsequent use and ensuring the quality of the paper roll.

[0066] Optionally, the paper roll strength detection structure 800 includes: a housing 801, a micro switch 802, a swing rod 803, a spring 804, a swing arm 805, and a detection rod 806. The housing 801 is disposed between the machine base 100 and the winding roll 300, and is located on the upper side of the paper roll. The micro switch 802 is disposed inside the housing 801. The swing rod 803 is disposed on one side of the micro switch 802. One end of the spring 804 is connected to the inner wall of the housing 801, and the other end is connected to the swing rod 803. One end of the probe rod 806 is connected to the swing arm 803 to provide force for the swing arm 803 to move towards the micro switch 802. One end of the swing arm 805 is connected to the other end of the swing arm 803. One end of the probe rod 806 is connected to the other end of the swing arm 805, and the other end of the probe rod 806 rests on the conveyed paper roll. The micro switch 802 is connected to the controller assembly 700, which controls the start and stop of the unwinding roller 200 and the take-up roller 300 according to the on / off signal of the micro switch 802. Thus, during normal paper roll conveying, one end of the probe rod 806 abuts against the upper side of the conveyed paper roll. When the paper roll breaks under the action of the probe rod 806, the probe rod 806 drives the swing arm 803 to move via the swing arm 805, causing the swing arm 803 to separate from the micro switch 802. At this time, the controller assembly 700 controls the unwinding roller 200 and the take-up roller 300 to stop operating according to the off signal of the micro switch 802, ensuring the quality of the paper roll.

[0067] Optionally, the paper roll strength detection structure 800 further includes a limiting rod 807. One end of the limiting rod 807 is fixed to the inner wall of the housing 801, and the other end abuts against one side of the swing arm 805 to limit the rotation of the swing arm 805. In this way, by using the limiting rod 807 to limit the rotation of the swing arm 805, the movement of the swing rod 803 is limited, so that the swing rod 803 can always stably contact and separate from the micro switch 802.

[0068] Optionally, the probe 806 is made of rubber, and the force exerted by the probe 806 on the paper roll is less than or equal to 1N. This keeps the force applied by the probe 806 to the paper roll within a small range, which can stably detect whether the strength at the glued position of the paper roll is up to standard, while also reducing the impact of the probe 806 on the paper strength and avoiding the situation where the probe 806 applies too much force, causing the intact paper roll to break.

[0069] like Figure 8 As shown, optionally, the paper roll rewinding detection device further includes an auxiliary bonding platform 900. The auxiliary bonding platform 900 is located below the paper roll and corresponds to the paper roll strength detection structure 800. The auxiliary bonding platform 900 is connected to the controller assembly 700. In the event of a breakage at the glued joint of the paper roll, the controller assembly 700 controls the auxiliary bonding platform 900 to re-bond the glued joint. Thus, in the event of a breakage at the glued joint of the paper roll, the auxiliary bonding platform 900 rises. The auxiliary bonding platform 900 has adhesive tape on it, which can bond the two ends of the paper roll together. The bonding method can be manual bonding, or the upper surface of the auxiliary bonding table 900 has a negative pressure generator. One end of the negative pressure generator is equipped with a tape pneumatic translation mechanism, and the other end is equipped with a tape cutting mechanism. When the two joints of the paper roll are bonded to the negative pressure generator, the tape is then pushed from the side by the pneumatic translation mechanism to bond the paper roll to the upper surface. Then the tape cutting mechanism cuts the tape, and the tape pneumatic translation mechanism drives the tape to reset, completing the bonding of the paper roll.

[0070] Combination Figure 9 As shown, this disclosure provides a control method for a paper roll rewinding detection device, including:

[0071] S01, Obtain mass information of both sides of the paper roll located in the area of ​​the opening of the containment space;

[0072] S02, in the case of a paper roll that is substandard, determine the horizontal length of the substandard portion of the paper roll, and

[0073] Control the downward pressing structure to move to above the defective portion of the paper roll;

[0074] S03, based on the horizontal length of the defective portion of the paper roll, control the pressing structure to press the defective portion of the paper roll into the receiving space by a set length, wherein the set length is half of the horizontal length of the defective portion of the paper roll;

[0075] S04, based on the movement of the pressing structure, control the paper roll processing structure to cut and bond the defective parts of the paper roll located in the receiving space.

[0076] The control method for the paper roll rewinding detection device provided in this embodiment can perform comprehensive inspection of the paper roll during the unwinding to rewinding process. In the case of unqualified paper roll quality, a positioning rewinding and waste removal function is implemented. That is, the pressing structure is controlled to move the unqualified part of the paper roll into the receiving space, and the shearing part is controlled to cut the unqualified part of the paper roll located in the receiving space. At the same time, the gluing part is controlled to bond the cut paper roll. This can efficiently and quickly remove unqualified parts from the paper roll and quickly continue operation without changing the roll or rewinding and waste removal, reducing the complexity of the process, saving time, and improving the quality inspection efficiency.

[0077] Understandably, the quality information of a paper roll includes whether the roll is damaged and whether it has stains or other dirt.

[0078] Optionally, obtaining the quality information of both sides of the paper roll located in the opening area of ​​the receiving space includes: using one detection component to detect the quality information of the upper side of the paper roll located in the opening area of ​​the receiving space, while the other detection component detects the quality information of the lower side of the paper roll located in the opening area of ​​the receiving space. This allows for efficient and rapid independent detection of both sides of the paper roll, ensuring the reliability of the detection results, avoiding omissions, and guaranteeing the quality of the paper roll.

[0079] Optionally, determining the horizontal length of the defective portion of the paper roll includes: if the quality of the upper side of the paper roll is defective, controlling the second detection unit located above the paper roll to measure the horizontal length of the defective portion on the upper side of the paper roll; if the quality of the lower side of the paper roll is defective, controlling the second detection unit located below the paper roll to measure the horizontal length of the defective portion on the upper side of the paper roll. In this way, when the quality of the paper roll is defective, the horizontal lengths of the defective portions on both the upper and lower sides of the paper roll are determined separately, facilitating subsequent waste removal operations and ensuring the accuracy of waste removal.

[0080] Optionally, determining the horizontal length of the defective portion of the paper roll further includes: when there are quality defects on both sides of the paper roll, controlling two second detection sections to measure the horizontal length of the defective portion on the upper and lower sides of the paper roll respectively, and taking the two endpoints closest to the edge of the receiving space opening after measurement as the starting ends, the length between the starting ends is the horizontal length of the paper roll's quality defect. This allows for a more precise determination of the range of quality defects in the paper roll, facilitating better subsequent waste removal operations, avoiding omissions, and ensuring the accuracy of waste removal.

[0081] Optionally, controlling the movement of the pressing structure to above the defective portion of the paper roll includes: controlling the mounting frame to extend by a first predetermined length, and then controlling the pressing roller to extend by a second predetermined length, wherein the first predetermined length is greater than the height of the receiving space, and the second predetermined length is greater than or equal to the width of the machine. This ensures that the pressing roller can stably and neatly press the paper roll into the receiving space, and also more accurately presses the contaminated portion of the paper roll into the receiving space, facilitating subsequent precise cutting and waste removal of the paper roll. This avoids cutting the acceptable portion of the paper roll, ensuring cutting accuracy while preventing waste of the paper roll.

[0082] Optionally, controlling the pressing structure to move the defective portion of the paper roll into the receiving space by a predetermined length based on the horizontal length of the defective portion includes: determining a first horizontal distance and a second horizontal distance between the defective paper rolls located on both sides of the detection component and the detection component, centered on the detection component above the paper roll; controlling the unwinding roller to rotate clockwise a first predetermined number of revolutions based on the first horizontal distance; and controlling the rewinding roller to rotate clockwise a predetermined number of revolutions based on the second horizontal distance.

[0083] Rotate counterclockwise a second set number of times, wherein the first horizontal distance is equal to the first set number of rotations, and the second horizontal distance is equal to the second set number of rotations.

[0084] The number of turns is set to be equal, and the first and second set number of turns refer to the total circumference after the unwinding and rewinding rollers have rotated, respectively. In this way, all the defective parts of the paper roll can be accurately pushed into the receiving space, avoiding the need to cut the qualified parts of the paper roll, ensuring the accuracy of the cutting while avoiding waste of the paper roll.

[0085] Optionally, according to the movement of the pressing structure, controlling the paper roll processing structure to cut and bond the defective parts of the paper roll located in the receiving space includes: when the pressing structure stops moving, controlling the cutting part to cut the defective parts of the paper roll located in the receiving space, and simultaneously controlling the bonding part to bond the cut paper roll. In this way, when the pressing structure stops moving, it indicates that all the defective paper rolls have entered the receiving space. At this point, controlling the cutting part to cut the defective parts of the paper roll located in the receiving space, and controlling the bonding part to bond the cut paper roll, can accurately cut the defective parts of the paper roll, ensuring the accuracy and stability of waste removal. Bonding the paper roll while cutting ensures that the paper roll continues to be conveyed in an orderly manner, simplifying the waste removal process, saving time, and improving the efficiency of waste removal and paper roll conveying.

[0086] Optionally, based on the movement of the pressing structure, after controlling the paper roll processing structure to cut and bond the defective parts of the paper roll located in the receiving space, the process includes: detecting the position information of the paper roll bonding point; if the paper roll moves from the bonding point to the position of the paper roll strength detection structure, detecting the bonding strength at the bonding point; and controlling the start and stop of the unwinding and rewinding rollers, as well as the auxiliary bonding table, based on the bonding strength at the bonding point. This allows for the detection of the bonding strength at the bonding point, and if breakage occurs at the bonding point, the unwinding and rewinding rollers are stopped, facilitating the auxiliary bonding table to bond the paper roll. This prevents unstable bonding at the bonding point from affecting subsequent use and ensures the quality of the paper roll.

[0087] Optionally, based on the bonding strength at the paper roll gluing point, the start and stop of the unwinding and rewinding rollers, as well as the start and stop of the auxiliary gluing table, are controlled. This includes: in the event of a breakage at the paper roll gluing point, controlling the unwinding and rewinding rollers to stop rotating, and controlling the auxiliary gluing table to move upwards to re-glu the broken paper roll. Thus, in the event of a breakage at the paper roll gluing point, the auxiliary gluing table rises, and the table, equipped with adhesive tape, can bond the two ends of the paper roll together. The bonding method can be manual bonding, or the auxiliary gluing table can have a negative pressure generator on its upper surface. One end of the negative pressure generator has a pneumatic tape translation mechanism, and the other end has a tape cutting mechanism. When the two joints of the paper rolls are bonded to the negative pressure generator, the tape is pushed from the side by the pneumatic translation mechanism to bond the paper rolls on the upper surface. Then, the tape cutting mechanism cuts the tape, and the pneumatic tape translation mechanism drives the tape to reset, completing the bonding of the paper rolls.
