Description

Technical Field

[0002] After the film base of the tape is coated with glue, a single-sided adhesive tape is formed.

[0003] During the winding process of the tape master, the moisture content in the adhesive layer can be measured with a moisture meter to avoid the problem that the moisture content of the adhesive layer is too high or too low and cannot be discovered in time. The fluctuation of the moisture content of the adhesive layer is caused by insufficient mixing of the adhesive liquid or stratification. Once discovered, the adhesive liquid needs to be treated accordingly.

[0004] In the prior art, moisture meters are generally not standardly equipped on production lines and need to be installed later. During the later installation process, different types of production equipment and even different installation locations may cause the inclination of the tape to be inconsistent. The moisture meter is a device based on the infrared principle, so it is crucial to ensure that the measuring end of the moisture meter is level with the tape. Utility Model Content

DETAILED DESCRIPTION

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0024] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] The utility model embodiment provides a tape moisture measurement device, such as Figure 1-3 As shown, it includes a connecting frame 1, and rotating frames 2 are rotatably installed on the upper parts of both sides of the connecting frame 1. A power mechanism for driving the rotating frame 2 to rotate is installed at one end of the connecting frame 1. An axial moving mechanism is installed on the rotating frame 2, and a moisture meter 7 is connected to the axial moving mechanism; the axial moving mechanism in the running state is used to drive the moisture meter 7 to reciprocate along the length direction of the axial moving mechanism; the moisture meter 7 is used to measure the moisture of the undivided tape mother tape.

[0026] In this embodiment, during the process of the tape being wound, the tape presents different states at different positions (such as horizontal or tilted upward or tilted downward). According to the convenient installation position of the production line, the connecting frame 1 is installed at a certain position of the production equipment, and of course, the position needs to be behind the glue coating section;

[0027] According to the tilt state of the tape mother at the installation position, the power mechanism is started, and the power mechanism pulls the rotating frame 2 to rotate relative to the connecting frame 1 until the measuring end (infrared transmitter and infrared receiver) of the moisture meter 7 is parallel to the tape mother passing through the position;

[0028] After installation, the moisture meter 7 is driven to reciprocate along the axial moving mechanism by starting the axial moving mechanism, and then the moisture content of the tape master is measured. The phenomenon used by the online infrared moisture meter 7 is that many substances absorb infrared energy at a specific wavelength, but do not absorb infrared energy at other wavelengths. When measuring the water content of the measured substance, at least two wavelengths are selected, one of which is a reference wavelength that will not be strongly absorbed by the measured substance or water;

[0029] The other is to measure wavelengths that are not strongly absorbed by the substance being measured, but are strongly absorbed by water. The online infrared moisture meter uses a precision infrared filter mounted on a rotating wheel. This installation allows pulses of reference light and measurement light to pass through the filter alternately;

[0030] The retained beam is focused onto the object under test, first the reference beam is projected onto the sample, then the measurement beam is projected onto the object.

[0031] The two timed light energy pulses will be reflected back to a detector and converted into two electrical signals in sequence. The reference channel represents the expected amount of reflected energy, and a portion of the measurement channel is absorbed by water molecules, so its energy will be attenuated. The two signals are combined to form a ratio. The difference between this ratio and other ratios obtained from samples with different moisture contents is directly proportional to the difference in moisture content between the two, thus forming a moisture determination effect.

[0032] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the axial movement mechanism includes a driving motor 3 installed outside a rotating frame 2, the output end of the driving motor 3 is connected to a reciprocating screw rod 4, and the other end of the reciprocating screw rod 4 is rotatably connected to the other rotating frame 2 through a bearing;

[0033] A guide rod 6 is fixedly connected to the reciprocating screw 4 and is arranged horizontally between the two rotating frames 2 and below the reciprocating screw 4. A sliding sleeve 5 is slidably connected to the outer wall of the reciprocating screw 4 through a screw seat, and the sliding sleeve 5 is slidably connected to the guide rod 6. A moisture meter 7 is installed on one end of the sliding sleeve 5 through a mounting seat.

[0034] In this embodiment, the reciprocating screw rod 4 has two thread grooves with the same pitch and opposite rotation directions on its surface, and the two ends are connected by a transition curve;

[0035] When the drive motor 3 is started, the drive motor 3 drives the reciprocating screw 4 to rotate. When the reciprocating screw 4 rotates, the drive screw seat moves axially along the surface of the reciprocating screw 4, and the screw seat drives the sliding sleeve 5 to move along the guide rod 6. At the same time, the sliding sleeve 5 drives the moisture meter 7 to move back and forth. The reciprocating moisture meter 7 measures the moisture content of the wound tape. If the glue content on the tape exceeds the standard, it will be discovered by the moisture meter 7 and then sent to the sound and light alarm electrically connected to it through the controller.

[0036] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the output end of the driving motor 3 penetrates the inner side of the rotating frame 2, and the output end of the driving motor 3 is rotatably connected with the contact position of the rotating frame 2 through a bearing.

[0037] In this embodiment, the friction between the driving motor 3 and the rotating frame 2 is reduced.

[0038] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the power mechanism includes a mounting plate 12 installed on the side of one end of the connecting frame 1, the top end of the mounting plate 12 is rotatably connected to an electric push cylinder 11, the output end of the electric push cylinder 11 is connected to a connecting rod 10, the outer wall of the connecting rod 10 is slidably connected to a sliding frame 8, and the interior of the sliding frame 8 is provided with a sliding groove 9 for the connecting rod 10 to slide; one end of the sliding frame 8 is fixedly connected to the end of a rotating frame 2.

[0039] In this embodiment, when the moisture meter 7 is adjusted according to the tilt state of the tape mother, the electric push cylinder 11 is controlled to operate, and the electric push cylinder 11 drives the connecting rod 10 at its output end to move, and the connecting rod 10 pulls the sliding frame 8 to rotate with the rotation point of the connecting frame 1 and the rotating frame 2 as the center, thereby achieving the purpose of adjusting the angle of the moisture meter 7.

[0040] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a calibration mechanism is arranged on the outer side of a rotating frame 2, and the calibration mechanism is used to determine whether the output end of the moisture meter 7 is parallel to the tape mother tape. The calibration mechanism includes a slide rail 14 vertically opened on the outer side of a rotating frame 2, and a slider 15 is slidably connected to the inner wall of the slide rail 14 up and down, and a calibration ruler 13 is formed on the outer side of the slider 15.

[0041] In this embodiment, during the adjustment process, it is sufficient to visually check whether the calibration ruler 13 and the rolled-up tape are in the same level. If there is a height difference between the calibration ruler 13 and the tape, the calibration ruler 13 is pulled, and the calibration ruler 13 drives the slider 15 to move up and down along the slide rail 14, so that the calibration ruler 13 and the tape can be adjusted to the same height, and then visually judge whether the two overlap.

[0042] Thereby completing the parallelism of the moisture meter 7 and the adhesive tape master.

[0043] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the cross sections of the slide rail 14 and the slider 15 are both convex structures, and the inner wall of the slide rail 14 is provided with friction rubber.

[0044] In this embodiment, the friction rubber is used to increase the friction between the slide rail 14 and the slider 15 so that the slide rail 14 can be kept at the current position when no external force is applied.
