Description

Technical Field

[0001] This utility model relates to the field of self-adhesive label technology, specifically to a self-adhesive label automatic detection correction device. Background Technology

[0002] Self-adhesive labels (pressure-sensitive labels) typically require continuous transport via conveyor systems during the printing, die-cutting, and inspection processes to enable visual inspection (e.g., for printing defects, die-cutting deviations, stains, etc.).

[0003] According to a visual inspection device for label paper production (Announcement No.: CN218726739U), the above application uses a forward or reverse handle to make two moving rollers move closer to each other or further apart, thereby keeping the label paper taut and ensuring that the label paper collection point can continuously maintain horizontal movement.

[0004] However, in the aforementioned application, the label may shift laterally during transmission due to factors such as uneven tension, guide roller installation errors, or material deformation. Simply tightening the label cannot automatically correct the shift, causing the detection area to deviate from the predetermined position and affecting the detection accuracy. Utility Model Content

[0005] The purpose of this invention is to provide an automatic detection and correction device for self-adhesive labels, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic detection correction device for self-adhesive labels, comprising a fixed frame, a guide roller rotatably connected to the surface of the fixed frame, a rotating roller rotatably connected to the outer surface of the fixed frame, and a correction component and a limiting component provided on the outer surface of the fixed frame;

[0007] The correction components include:

[0008] Positioning plate, used in conjunction with movable plate to prevent self-adhesive labels from shifting;

[0009] A cavity is used to stabilize its internal structure.

[0010] The card block is used to limit the movement of the moving plate.

[0011] Preferably, the positioning plate is disposed on the surface of the rotating roller, the rotating roller passes through the positioning plate, and the positioning plate is rotatably connected to the rotating roller. A stabilizing rod is fixed to the outer surface of the fixing frame, the stabilizing rod passes through the positioning plate, and the stabilizing rod is fixedly connected to the positioning plate. A movable plate passes through and is rotatably connected to the rotating roller, the stabilizing rod passes through the movable plate, and the stabilizing rod is slidably connected to the movable plate. A cavity is formed inside the movable plate, and a locking block is slidably connected to the inner wall of the cavity. The locking block passes through the movable plate, and the locking block is slidably connected to the movable plate. A movable rod is hinged to the end of the locking block away from the stabilizing rod. The movable rod is hinged to a connecting plate at the end furthest from the locking block. The connecting plate is slidably connected to the inner wall of the cavity. A spring is fixed to the side of the connecting plate closest to the cavity, and the end of the spring furthest from the connecting plate is also fixed to the inner wall of the cavity. A sliding rod is fixed to the side of the connecting plate furthest from the spring, and the end of the sliding rod furthest from the connecting plate passes through the movable plate, slidably connected to the movable plate. When the movable plate moves towards the label, the inclined surface of the locking block contacts the inner wall of the slot, causing the locking block to retract into the cavity. Simultaneously, the movable rod flips and pulls the connecting plate to compress the spring, causing the sliding rod to slide into the cavity. At this time, the locking strip of the fixing ring slides within the movable groove without obstructing the movement of the sliding rod. When the locking block aligns with the slot, the spring releases its elastic force, pushing the locking block into the slot, ensuring the positioning plate and the movable plate are tightly fitted against the label surface. This ensures the label remains stable and does not shift during transmission, and automatically adapts to labels of different widths.

[0012] Preferably, the limiting component includes a stabilizing groove located at the top of the movable plate. A fixing ring is rotatably connected to the outer surface of the movable plate. A sliding groove is formed at the bottom of the fixing ring. A stabilizing column is slidably connected to the inner wall of the sliding groove. A second spring is fixed to the top of the stabilizing column, and the top of the second spring is fixed to the top of the inner wall of the sliding groove. A locking strip is fixed to the inner side of the fixing ring. A movable groove and an annular groove are formed on the outer surface of the sliding rod, communicating with the movable groove. Rotating the fixing ring causes the locking strip to embed into the annular groove and engage with it. Simultaneously, the stabilizing column is guided by the arc-shaped surface to slide into the sliding groove, compressing the second spring. When the stabilizing column aligns with the stabilizing groove, the second spring rebounds and locks it into the groove, locking the fixing ring. This locking mechanism restricts the movement of the connecting mechanism and the locking block by fixing the sliding rod, thereby maintaining the stability of the movable plate and ensuring accurate and reliable label correction.

[0013] Preferably, a fixing plate is fixed to the outer surface of the fixing frame, and an industrial camera is installed at the bottom of the fixing plate to facilitate inspection work.

[0014] Preferably, the end of the card block away from the movable rod has a triangular cross-section, which allows it to abut against the inner wall of the card slot as it moves with the movable plate, thus enabling the card block to reciprocate.

[0015] Preferably, the bottom of the stabilizing column is designed to be arc-shaped, so that the stabilizing column can reciprocate into the sliding groove as the fixing ring rotates.

[0016] Compared with the prior art, this utility model provides an automatic detection and correction device for self-adhesive labels, which has the following advantages:

[0017] 1. This self-adhesive label automatic detection and correction device, through its set correction components, allows the label to be placed between the positioning plate and the movable plate when detection is required. Pulling the movable plate causes the inclined surface of the locking block to contact the inner wall of the slot, retracting the locking block into the cavity. Simultaneously, the movable rod flips and pulls the connecting plate to compress the first spring, causing the sliding rod to slide into the cavity. When the locking block aligns with the slot, the first spring releases its elasticity, pushing the locking block into the slot, ensuring a tight fit between the positioning plate and the movable plate against the label surface. The label remains stable and does not shift during transport. The positioning plate limits the movement of the label by the movable plate, and it can automatically adapt to labels of different widths.

[0018] 2. The self-adhesive label automatic detection correction device, through the set limit components, when the movable plate is adjusted to the correct position, rotates the fixed ring, and the stabilizing column enters the stabilizing groove. The stabilizing fixed ring prevents rotation, and at the same time, the position of the locking strip is staggered with the movable groove, so that the sliding rod, connecting plate, movable rod and locking block are limited, thus preventing the movable plate from moving and avoiding label offset.

[0026] like Figures 1-6 As shown, this utility model provides a technical solution: an automatic detection and correction device for self-adhesive labels, including a fixed frame 1, a guide roller 2 rotatably connected to the surface of the fixed frame 1, a rotating roller 5 rotatably connected to the outer surface of the fixed frame 1, and a correction component 6 and a limiting component 7 provided on the outer surface of the fixed frame 1; the correction component 6 includes: a positioning plate 60, a movable plate 61, a cavity 62, a locking block 63, a movable rod 64, a connecting plate 65, a spring 66, a slot 67, a sliding rod 68, and a stabilizing rod 69.

[0027] A positioning plate 60 is disposed on the surface of the rotating roller 5, the rotating roller 5 passes through the positioning plate 60, and the positioning plate 60 is rotatably connected to the rotating roller 5. A stabilizing rod 69 is fixed on the outer surface of the fixing frame 1, the stabilizing rod 69 passes through the positioning plate 60, and the stabilizing rod 69 is fixedly connected to the positioning plate 60. A movable plate 61 passes through and is rotatably connected to the rotating roller 5, the stabilizing rod 69 passes through the movable plate 61, and the stabilizing rod 69 is slidably connected to the movable plate 61. A cavity 62 is formed inside the movable plate 61, and the inner wall of the cavity 62 slides... A locking block 63 is connected to the movable plate 61, and the locking block 63 is slidably connected to the movable plate 61. A movable rod 64 is hinged to the end of the locking block 63 away from the stabilizing rod 69. A connecting plate 65 is hinged to the end of the movable rod 64 away from the locking block 63. The connecting plate 65 is slidably connected to the inner wall of the cavity 62. A spring 66 is fixed to the side of the connecting plate 65 near the cavity 62. The end of the spring 66 away from the connecting plate 65 is fixed to the inner wall of the cavity 62. A slide rod 68 is fixed to one side of spring 66. The end of slide rod 68 away from connecting plate 65 passes through movable plate 61, and slide rod 68 is slidably connected to movable plate 61. The cross-section of the end of locking block 63 away from movable rod 64 is triangular. When movable plate 61 is pulled closer to the label, the inclined surface of locking block 63 abuts against the inner wall of locking groove 67. At this time, locking block 63 moves into cavity 62. Simultaneously, movable rod 64 flips, pulling connecting plate 65 closer to stabilizing rod 69. At this time, spring 66 is compressed. At the same time, the slide bar 68 is moved into the cavity 62. At this time, the locking strip 75 moves in the movable groove 76 and will not affect the normal movement of the slide bar 68 and the connecting plate 65. When the position of the locking block 63 is parallel to the slot 67, the spring 66 is released, which allows the locking block 63 to enter the slot 67. The surfaces of the positioning plate 60 and the movable plate 61 are in contact with the label, so that the label can only be transferred between the positioning plate 60 and the movable plate 61 without deviation, and can adapt to labels of different widths.

[0028] The limiting component 7 includes a stabilizing groove 70, which is formed on the top of the movable plate 61. A fixing ring 71 is rotatably connected to the outer surface of the movable plate 61. A sliding groove 72 is formed at the bottom of the fixing ring 71. A stabilizing column 73 is slidably connected to the inner wall of the sliding groove 72. A second spring 74 is fixed to the top of the stabilizing column 73. The top of the second spring 74 is fixed to the top of the inner wall of the sliding groove 72. A retaining strip 75 is fixed to the inner side of the fixing ring 71. A movable groove 76 is formed on the outer surface of the sliding rod 68. An annular groove 77 is formed on the outer surface of the sliding rod 68. The stabilizing column 73, which communicates with the movable groove 76, has an arc-shaped bottom. When the surfaces of the positioning plate 60 and the movable plate 61 are in contact with the label, rotating the fixing ring 71 causes the locking strip 75 to enter the annular groove 77 and intersect with each other. Simultaneously, as the fixing ring 71 rotates, the arc-shaped surface of the stabilizing column 73 contacts the inner wall of the stabilizing groove 70, pushing the stabilizing column 73 into the slide groove 72 and compressing the second spring 74. When the stabilizing column 73 is aligned with the stabilizing groove 70, the second spring 74 releases its elastic force, causing the stabilizing column 73 to enter the stabilizing groove 70, thereby locking the fixing ring 71 to prevent rotation. At this time, the slide rod 68 is fixed, thereby restricting the movement of the connecting plate 65, the movable rod 64, and the locking block 63, ultimately keeping the movable plate 61 stable and ensuring that the label correction process is not disturbed. A fixing plate 3 is fixed to the outer surface of the fixing frame 1, and an industrial camera 4 is installed at the bottom of the fixing plate 3 for easy label inspection.

[0029] When self-adhesive labels need to be inspected, the labels are transported via the surfaces of guide rollers 2 and rotating rollers 5, and simultaneously placed between positioning plate 60 and movable plate 61. When inspection is required, movable plate 61 is pulled closer to the label, at which point the inclined surface of locking block 63 abuts against the inner wall of locking groove 67, and locking block 63 moves into cavity 62. At the same time, movable rod 64 flips, pulling connecting plate 65 closer to stabilizing rod 69. At this time, spring 66 is compressed, simultaneously driving slide rod 68 to move into cavity 62. Locking strip 75 moves within movable groove 76, without affecting the normal movement of slide rod 68 and connecting plate 65. When locking block 63 is parallel to locking groove 67, spring 66 is released, allowing locking block 63 to enter locking groove 67. When positioning plate 60 and movable plate 61... When the surface is attached to the label, the fixing ring 71 is rotated, causing the locking strip 75 to enter the annular groove 77. At the same time, the locking strip 75 and the movable groove 76 are intersected. As the fixing ring 71 rotates, the arc-shaped surface of the stabilizing column 73 abuts against the inner wall of the stabilizing groove 70. At this time, the stabilizing column 73 enters the sliding groove 72, and the second spring 74 is compressed. When the position of the stabilizing column 73 is parallel to the stabilizing groove 70, the second spring 74 is released, and the stabilizing column 73 enters the stabilizing groove 70, thus stabilizing the fixing ring 71 and preventing the fixing ring 71 from rotating. At this time, the sliding rod 68 cannot move, which limits the connecting plate 65, the movable rod 64, and the locking block 63. At this time, the movable plate 61 cannot move, so as to avoid affecting the label correction work. At this time, the industrial camera 4 can be turned on, and the industrial camera 4 transmits the captured image to the computer to judge the quality.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
