Description

Technical Field

[0001] This invention relates to the field of label detection technology, specifically a label detection structure. Background Technology

[0002] Label stickers, also known as index paper or mouth-licking paper, originally had a layer of glue on them. You could lick it and stick it to the side of the paper to write annotations or numbers, hence the name. Self-adhesive labels, also called pressure-sensitive labels, are composite materials made of paper, film, or special materials as the face stock, coated with adhesive on the back, and protected by a silicone-coated backing paper. After printing and die-cutting, they become finished labels. When using them, simply peel them off the backing paper and press gently onto the surface of various substrates. After production, labels need to be tested using label inspection equipment to determine their quality.

[0003] However, traditional label inspection equipment uses bolts to limit the winding rollers when installing or replacing label rolls. Replacing the rollers requires removing the bolts, and installing them again requires tightening them, resulting in low efficiency and impacting overall label inspection efficiency. When the entire roll of labels is inspected, the labels may become loose on the winding rollers due to inadequate end securing, affecting storage and transport. Traditional inspection equipment uses bolts and pins to adjust the position of the adjusting rollers, which is cumbersome. Improper adjustment can lead to uneven stress on the labels during transport. Furthermore, when some labels are marked as defective due to quality issues, these defective labels are collected along with the qualified ones, affecting their subsequent use.

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] like Figures 1-15 As shown, the label detection structure of the present invention includes a detection machine body 1 and a conveying structure 2. The conveying structure 2 is provided on the detection machine body 1. The conveying structure 2 includes a rotating shaft 202, which is rotatably connected to the detection machine body 1. An installation sleeve 203 is detachably connected to the rotating shaft 202. A winding reel 204 is fixedly connected to the installation sleeve 203. The detection machine body 1 is provided with two adjusting rollers 206, multiple fixed rollers 205, a guide wheel 207, an observation plate 208, and a dust brush 209. One of the rotating shafts 202 on the right side for winding is fixedly connected to the output shaft of a motor 201. The motor 201 is fixed to the detection machine body 1.

[0042] Mounting structure 3 is provided on the rotating shaft 202. The mounting structure 3 includes a pressing rod 303, which is slidably connected to the rotating shaft 202. A tension spring 304 is fixedly connected between the pressing rod 303 and the rotating shaft 202. The end section of the pressing rod 303 is a V-shaped structure. The pressing rod 303 is provided with two inclined guide grooves 305. A guide shaft 306 is slidably connected inside the guide grooves 305. The guide shaft 306 is rotatably connected to a locking block 307. The rotating shaft 202 and the locking block 307 are slidably connected. The locking block 307 is engaged with a locking groove 308, which is provided on the mounting sleeve 203.

[0043] Visual camera 8 is provided on the main body 1 of the detection machine;

[0044] Tag sensor 9 is provided on the main body 1 of the detection machine;

[0045] The mounting structure 3 also includes positioning blocks 301. Two positioning blocks 301 are fixedly connected to the rotating shaft 202. The positioning blocks 301 are slidably connected to the positioning groove 302, which is located on the mounting sleeve 203. That is, the label paper starts from one take-up reel 204, passes around multiple fixed rollers 205 and adjusting rollers 206, and is fixed on another take-up reel 204. The guide wheel 207 limits its movement. When working, the motor 201 is started, which drives a rotating shaft 202 on the right side for take-up to rotate. The rotation of the rotating shaft 202 drives the mounting sleeve 203 to rotate, and the rotation of the mounting sleeve 203 drives the take-up reel 204 to rotate. At this time, one take-up reel 204 releases the label paper, and the other take-up reel 204 collects the label paper. Before reaching the observation plate 208, the label paper is swept clean of dust by the dust brush 209. When passing the observation plate 208, it is detected by the vision camera 8 at the top, which distinguishes between qualified and unqualified label paper. The qualified label paper is guided through several times. The label paper is wound backward by the take-up reel 204. When the take-up reel 204 needs to be replaced after each set of label papers has been inspected, the press lever 303 can be pressed. The tension spring 304 extends, and the sliding of the press lever 303 will drive the guide groove 305 to move, which in turn causes the guide shaft 306 to roll inside the guide groove 305. Since the guide groove 305 is inclined, the rolling of the guide shaft 306 will drive the locking block 307 to slide out of the locking groove 308 on the mounting sleeve 203, thereby locking the mounting sleeve 203 with the mounting sleeve 203. When the take-up reel 204 is pulled out and a new take-up reel 204 is replaced, simply align the positioning groove 302 on the mounting sleeve 203 with the positioning block 301 on the rotating shaft 202, and then insert the mounting sleeve 203. Since the end of the locking block 307 is trapezoidal, the locking block 307 slides down first, and the tension spring 304 extends. When the locking groove 308 reaches the position of the locking block 307, the locking block 307 will be locked into the inside of the locking groove 308 due to the reset action of the tension spring 304, thereby preventing the take-up reel 204 from sliding.

[0046] Specifically, the mounting sleeve 203 is provided with a rotating structure 4, which includes a mounting ring 401. The mounting ring 401 is rotatably connected to the mounting sleeve 203. The mounting ring 401 has a plurality of insertion holes 402 arranged in a circular array. An insertion rod 403 is slidably connected inside one of the insertion holes 402. The insertion rod 403 is slidably connected to the mounting sleeve 203. A first spring 406 is fixedly connected between the insertion rod 403 and the mounting sleeve 203. A connecting rod 404 is fixedly connected to the insertion rod 403. A rotating block 405 is rotatably connected to the connecting rod 404. The mounting sleeve 203 is provided with a stop bar 407.

[0047] The mounting ring 401 is provided with a clamping structure 5, which includes a mounting bracket 501. The mounting bracket 501 is fixedly connected to the mounting ring 401. A sliding plate 507 is slidably connected to the mounting bracket 501. The sliding plate 507 is provided with two limiting grooves 506. A lever 502 is slidably connected to the mounting bracket 501. A limiting strip 505 is fixedly connected to the lever 502. The limiting strip 505 is slidably connected to the mounting bracket 501 and engages with the limiting grooves 506. A guide rod 503 is fixedly connected to the lever 502 and slidably connected to the mounting bracket 501. A second spring 504 is fixedly connected to the lever 502 and the mounting bracket 501.

[0048] A clamping plate 508 is slidably connected to the sliding plate 507. A third spring 510 is fixedly connected between the clamping plate 508 and the sliding plate 507. A guide strip 509 is fixedly connected to the sliding plate 507, and the guide strip 509 passes through the third spring 510. The clamping plate 508 and the guide strip 509 are slidably connected. A push block 511 is fixedly connected to the clamping plate 508. That is, when the label paper is stored properly, the lever 502 can be slid down. Sliding the lever 502 down will cause the limiting strip 505 to not be in contact with the limiting strip on the sliding plate 507. The slot 506 engages, the second spring 504 is compressed, and the guide rod 503 prevents the second spring 504 from deviating. At this time, the sliding plate 507 slides. After the sliding plate 507 slides, the lever 502 is released. Under the reset action of the second spring 504, the limiting strip 505 will be driven into the interior of another limiting slot 506. At this time, the sliding push block 511 drives the clamping plate 508 to slide, the third spring 510 is compressed, and then the end of the label is placed at the notch exposed on the sliding plate 507. Then the push block 511 is released, and the third spring 510 resets. Under the action, the clamping plate 508 will cooperate with the sliding plate 507 to clamp the end of the label paper. The guide strip 509 prevents the third spring 510 from deviating and improves the stability of the clamping plate 508 when sliding. After clamping, the rotating block 405 can be pulled. The rotating block 405 drives the connecting rod 404 to slide together, and the first spring 406 is compressed. At this time, the insertion rod 403 can slide and no longer be stuck in the insertion hole 402. Then, the rotating block 405 is rotated. After rotating 90 degrees, the groove on the rotating block 405 will abut against the stop rod 407, thereby facilitating the insertion rod. 403 is used for limiting. At this time, the mounting ring 401 can be rotated according to the reserved length of the label paper. The rotation of the mounting ring 401 will drive the mounting bracket 501 to rotate, which will in turn change the position of the sliding plate 507 and the clamping plate 508, so that the label paper can be stretched more tightly and avoid the label paper from becoming loose when wrapped. After rotating to the appropriate angle, simply slide the rotating block 405 to the right first, and then rotate the rotating block 405. Under the reset action of the first spring 406, the insertion rod 403 will be driven to insert into the insertion hole 402 to limit the mounting ring 401.

[0049] Specifically, the adjusting roller 206 is provided with an adjusting structure 6, which includes a sliding sleeve 601. The adjusting roller 206 is fixedly connected to the sliding sleeve 601, and the sliding sleeve 601 is slidably connected to the slide rail 602. The slide rail 602 is fixed to the main body 1 of the testing machine. A pressing block 603 is slidably connected to the slide rail 602, and the pressing block 603 is fixed to the connecting strip 604. The connecting strip 604 is slidably connected to the slide rail 602. The connecting strip 604 is provided with a plurality of equidistant adjusting blocks 605, which engage with adjusting grooves 606 located on the sliding sleeve 601. A fourth spring 608 is fixedly connected between the connecting strip 604 and the slide rail 602. A guide block 607 is fixedly connected to the slide rail 602. 607 passes through the fourth spring 608, and the connecting strip 604 is slidably connected to the guide block 607; that is, when it is necessary to adjust the height of the adjusting roller 206, it is only necessary to press the pressing block 603. The pressing block 603 drives the connecting strip 604 to slide, and the fourth spring 608 retracts. At this time, the adjusting block 605 on the connecting strip 604 is no longer engaged with the adjusting groove 606 on the sliding sleeve 601. At this time, the sliding sleeve 601 can be slid up and down on the slide rail 602. After adjusting the sliding sleeve 601 to a suitable position, the pressing block 603 is released. Under the reset action of the fourth spring 608, the connecting strip 604 is driven to slide, and then the adjusting block 605 is driven to re-engage into the adjusting groove 606 on the sliding sleeve 601. The setting of the guide block 607 avoids the fourth spring 608 from deviating and improves the stability of the sliding of the connecting strip 604.

[0050] Specifically, the testing machine body 1 is provided with a fixing structure 7, which includes a connecting shaft 701. A gear 702 is rotatably connected to the testing machine body 1 via the connecting shaft 701. Two racks 703 mesh on both sides of the gear 702. The racks 703 are slidably connected to the testing machine body 1. A slider 704 is provided on the rack 703. The slider 704 is slidably connected to the testing machine body 1. A roller 706 is fixedly connected to the slider 704. One slider 704 is fixedly connected to the telescopic end of a hydraulic rod 705. A support plate 707 is fixedly connected to one slider 704. A fixing strip 708 is provided on the testing machine body 1. A guide post 709 is provided on the fixing strip 708. The support plate 707 is slidably connected to the guide post 709. That is: When the defective label paper is fed to the middle position of the two fixed rollers 205 on the right, the motor 201 is turned off and the hydraulic rod 705 is started. The hydraulic rod 705 retracts, causing the right slider 704 to slide down, which in turn causes the right rack 703 to slide down. The gear 702 rotates around the connecting shaft 701. The left rack 703 rises, causing the left slider 704 to rise, which in turn causes the two abutment rollers 706 to move towards each other. This, in turn, cooperates with the two fixed rollers 205 to fix the label paper on it. When the left slider 704 rises, it causes the support plate 707 to rise. The upper horizontal surface of the support plate 707 is flush with the upper end surface of the left abutment roller 706. Therefore, when the abutment roller 706 rises, it will cause the support plate 707 to hold the label paper, making the label tearing more stable. The fixed strip 708 is provided with guide posts 709 to make the sliding of the support plate 707 more stable.

[0051] In use, the label paper first starts from one take-up reel 204, passes around multiple fixed rollers 205 and adjusting rollers 206, and is then fixed on another take-up reel 204. Guide wheels 207 limit its movement. During operation, motor 201 is started, driving a rotating shaft 202 on the right side for winding. The rotation of shaft 202 causes the mounting sleeve 203 to rotate, which in turn causes the take-up reels 204 to rotate. At this time, one take-up reel 204 releases the label paper, while the other collects it. Before reaching the observation plate 208, the label paper is brushed clean of dust by a brush 209. Upon passing the observation plate 208, it is detected by the top vision camera 8, which distinguishes between qualified and unqualified labels. Qualified labels are wound up by the take-up reels 204 after several guiding passes. When each set of labels has been inspected, the take-up reel 204 needs to be replaced. Pressing the pressing rod 303 causes the tension spring 304 to extend. The sliding of the pressing rod 303 will cause the guide groove 305 to move, which in turn causes the guide shaft 306 to roll inside the guide groove 305. Since the guide groove 305 is inclined, the rolling of the guide shaft 306 will cause the locking block 307 to slide out of the locking groove 308 on the mounting sleeve 203, thereby removing the mounting sleeve 203 and the winding reel 204 on the mounting sleeve 203. When replacing the new winding reel 204, simply align the positioning groove 302 on the mounting sleeve 203 with the positioning block 301 on the rotating shaft 202, and then insert the mounting sleeve 203. Since the end of the locking block 307 is trapezoidal, the locking block 307 slides down first, and the tension spring 304 extends. When the locking groove 308 reaches the position of the locking block 307, the locking block 307 will be locked into the inside of the locking groove 308 due to the reset action of the tension spring 304, thereby preventing the winding reel 204 from sliding.

[0052] Then, after the label paper is stored, the lever 502 can be slid down. Sliding the lever 502 downwards will cause the limiting strip 505 to disengage from the limiting groove 506 on the slide plate 507, compressing the second spring 504. The guide rod 503 prevents the second spring 504 from deviating. At this time, slide the slide plate 507. After the slide plate 507 slides, release the lever 502. Under the reset action of the second spring 504, the limiting strip 505 will be driven into the other limiting groove 506. At this time, slide the push block 511, causing the clamping plate 508 to slide, compressing the third spring 510. Then, place the end of the label paper at the exposed notch of the slide plate 507, and then release the push block 511. Under the reset action of the third spring 510, the clamping plate 508 will cooperate with the slide plate 507 to clamp the end of the label paper. The guide rod 509 prevents the third spring 510 from deviating and also improves the sliding of the clamping plate 508. To ensure stability during clamping, after clamping, the rotating block 405 can be pulled, causing the connecting rod 404 to slide together. The first spring 406 is compressed, allowing the insertion rod 403 to slide without being jammed into the insertion hole 402. Then, the rotating block 405 is rotated. After rotating 90 degrees, the groove on the rotating block 405 will abut against the stop rod 407, thus limiting the insertion rod 403. At this time, the mounting ring 401 can be rotated according to the reserved length of the label paper. The rotation of the mounting ring 401 will drive the mounting bracket 501 to rotate, thereby changing the position of the sliding plate 507 and the clamping plate 508, so that the label paper can be stretched more tightly, preventing the label paper from becoming loose when wrapped. After rotating to the appropriate angle, simply slide the rotating block 405 to the right first, and then rotate the rotating block 405. Under the reset action of the first spring 406, the insertion rod 403 will be inserted into the insertion hole 402 to limit the mounting ring 401.

[0053] Secondly, when the height of the adjusting roller 206 needs to be adjusted, simply press the pressing block 603. The pressing block 603 drives the connecting strip 604 to slide, and the fourth spring 608 retracts. At this time, the adjusting block 605 on the connecting strip 604 is no longer engaged with the adjusting groove 606 on the sliding sleeve 601. The sliding sleeve 601 can then be slid up and down on the slide rail 602. After adjusting the sliding sleeve 601 to the appropriate position, release the pressing block 603. Under the reset action of the fourth spring 608, the connecting strip 604 slides, which in turn drives the adjusting block 605 to re-engage into the adjusting groove 606 on the sliding sleeve 601. The guide block 607 prevents the fourth spring 608 from deviating and improves the stability of the sliding of the connecting strip 604.

[0054] Finally, when the defective label is fed to the middle of the two fixed rollers 205 on the right, the motor 201 is turned off and the hydraulic rod 705 is started. The hydraulic rod 705 retracts, causing the right slider 704 to slide down, which in turn causes the right rack 703 to slide down. The gear 702 rotates around the connecting shaft 701, and the left rack 703 rises, causing the left slider 704 to rise, which in turn causes the two abutment rollers 706 to move towards each other, thus cooperating with the two fixed rollers 205 to fix the label on it. When the left slider 704 rises, it causes the support plate 707 to rise. The upper horizontal surface of the support plate 707 is flush with the upper end surface of the left abutment roller 706. Therefore, when the abutment roller 706 rises, it will cause the support plate 707 to hold the label, making the label tearing more stable. The fixed strip 708 is provided with guide posts 709 to make the sliding of the support plate 707 more stable.
