Description

Technical Field

[0001] The invention relates to the technical field of label testing equipment, in particular to a viscosity testing equipment for blank labels. Background Art

[0002] Labels are used to mark product targets and categories or contents. Most of the labels in the printing industry are printed materials used to identify the relevant instructions of their own products, and most of them have self-adhesive on the back. Therefore, after the label is produced, it is necessary to test the stickiness of the label.

[0003] For example, a label processing viscosity tester with announcement number CN220289361U includes a detection table, a test mechanism and a scraping mechanism. The test mechanism is located on the upper part of the detection table, and the scraping mechanism is installed on one side of the detection table. The test mechanism includes a frame, a hydraulic seat is arranged inside the frame, a protective shell is arranged on the front side of the hydraulic seat, a force sensor is arranged inside the protective shell, a buffer spring is arranged at the bottom of the force sensor, and an alloy pressure block is arranged at the bottom of the buffer spring. The alloy pressure block will generate a downward adsorption force when the alloy pressure block rises due to the adhesion of the label, so that the buffer spring will automatically deform, and by setting a force sensor, the force bearing capacity of the buffer spring can be detected, thereby testing the adhesion performance of the label. However, due to the large adhesion of the label, after the scraper scrapes the detection part, a small amount of sticky material may still remain at the detection part. If these sticky residues are not cleaned up, they may affect the accuracy of subsequent label detection, and the device is not convenient for separately detecting different positions of the label, and the detection has limitations.

The threaded rod 56 drives the bearing 57 to descend, and the bearing 57 drives the ring 58 to slide on the connecting rod 51, and the threaded rod 56 drives the pressure block 59 to move downward, so that the pressure block 59 is lower than the bottom surface of the contact plate 410, and then the screw rod 2 53 is rotated, and the lower sleeve 55 limits the slider 54, so that the screw rod 2 53 drives the slider 54 to move horizontally, and the slider 54 drives the lower sleeve 55 and the threaded rod 56 to move, and the threaded rod 56 drives the pressure block 59 and the contact plate 410 to move, and the connecting rod 51 is fitted with the connecting plate 48, so as to facilitate the adjustment of the position of the pressure block 59, facilitate the separate detection of the local position of the label, and improve the flexibility of detection.

[0046] Working principle: When using the device, first, Figure 1-Figure 11 As shown, by sticking one side of the label to be detected on the top of the placement plate 3, the servo motor 41 is started to rotate forward, the servo motor 41 drives the screw rod 42 to rotate, the screw rod 42 drives the adjustment sleeve 47 to move downward, the adjustment sleeve 47 drives the connecting plate 48 to move downward through the detection spring 49, and the connecting plate 48 drives the contact plate 410 to move downward through the threaded rod 56, so that the contact plate 410 is pressed against the other side of the label to be detected. At this time, the detection spring 49 is in a state of neither compression nor extension, and the annular force sensor 9 is not subjected to force.

[0047] Then reverse the servo motor 41, and the adjustment sleeve 47 drives the detection spring 49 to rise. The detection spring 49 is compressed. At this time, the detection spring 49 acts on the annular force sensor 9, and the annular force sensor 9 is connected to the external display device. Its specific working process refers to the prior art.

[0049] When the connecting plate 48 descends, the blocking plate 425 closes the sealing plate 424 to reduce the discharge of hot air from the inner cavity 413. After the contact plate 410 is heated for a period of time, the bottom surface of the contact plate 410 is adjusted to be flush with the top of the scraper 8, and the electric push rod 7 is started. The electric push rod 7 drives the scraper 8 to be pushed out, which facilitates the scraping of the placement plate 3 and the contact plate 410, thereby reducing the residual sticky material on the bottom surface of the contact plate 410.

[0050] When it is necessary to detect the local position of the label, rotate the threaded rod 56, and the threaded rod 56 is screwed out from the lower sleeve 55. The threaded rod 56 drives the bearing 57 to descend, and the bearing 57 drives the ring 58 to slide on the connecting rod 51, and the threaded rod 56 drives the pressure block 59 to move downward, so that the pressure block 59 is lower than the bottom surface of the contact plate 410, and then rotate the second screw rod 53, and the lower sleeve 55 limits the slider 54, so that the second screw rod 53 drives the slider 54 to move horizontally, and the slider 54 drives the lower sleeve 55 and the threaded rod 56 to move, and the threaded rod 56 drives the pressure block 59 and the contact plate 410 to move, and the connecting rod 51 is fitted with the connecting plate 48, so as to facilitate the adjustment of the position of the pressure block 59, facilitate the separate detection of the local position of the label, and improve the flexibility of detection.
