Description

Technical Field

[0001] This utility model belongs to the field of self-adhesive label testing technology, and in particular relates to a testing instrument for random inspection of self-adhesive label thickness. Background Technology

[0002] In today's highly automated packaging, printing, and manufacturing industries, self-adhesive materials (or self-adhesive label materials) play a crucial role. From food and beverage labels, pharmaceutical information labels, and logistics transportation labels to electronic component identification and industrial product labels, their applications are ubiquitous. The performance of self-adhesive materials, especially their thickness uniformity and consistency, directly affects the quality of the final product, production efficiency, and user experience.

[0003] When the laser emitter and receiver do not move synchronously, it can easily lead to measurement position deviation, affecting the accuracy of thickness detection. Furthermore, traditional inspection instruments struggle to flexibly adjust the measurement width, cannot adapt to different widths of self-adhesive labels, and lack height adjustment functionality, making them unsuitable for self-adhesive strips of varying thicknesses or production line positions at different heights. Therefore, we provide an inspection instrument for random inspection of self-adhesive label thickness to solve the aforementioned problems. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example 1

[0026] Please see Figures 1 to 5 This utility model is a testing instrument for random inspection of the thickness of self-adhesive labels. Through the combined use of cylinder 302 and electric lifting rod 2, it can perform random inspection of self-adhesive strips of different widths and heights. At the same time, it can be used in conjunction with synchronization strip 6, laser emitter 4 and laser receiver.

[0027] Specifically, the base plate 1 has an electric lifting rod 2 fixed to the right side of its upper surface. A U-shaped bar 3 is fixed to the lifting end of the electric lifting rod 2. A laser emitter 4 is installed on the upper surface of the U-shaped bar 3, and a laser receiver 5 is installed on the lower surface of the U-shaped bar 3. Sliding ports 305 are opened on both ends of the U-shaped bar 3. Two sets of cylinders 302 with piston ends located inside the sliding ports 305 are fixed on the side wall of the U-shaped bar 3. A synchronization bar 6 is installed on the inner side of the U-shaped bar 3. Sliding plates 601, which are bolted to the piston ends of the cylinders 302, are fixed at both ends of the synchronization bar 6. A controller 7 is fixed to the upper surface of the base plate 1. A reinforcing plate 101 is installed between the base plate 1 and the electric lifting rod 2, and both ends of the reinforcing plate 101 are connected to the base plate 1 and the electric lifting rod 2 by bolts.

[0028] The operation process of this embodiment is as follows: Using the above-described structure, when it is necessary to detect the thickness of the self-adhesive label, the entire device can be moved to the side of the self-adhesive label production equipment. The controller 7 controls the electric lifting rod 2, which in turn controls the U-shaped strip 3 to rise and fall synchronously, so that both ends of the U-shaped strip 3 are positioned above and below the self-adhesive label strip. By slightly moving the device, the laser emitter 4 and laser receiver are moved to a position directly above or below the self-adhesive label strip. Therefore, after the controller 7 operates the laser emitter 4 and laser receiver, the laser will detect the thickness of the self-adhesive label strip. Simultaneously, when it is necessary to detect the lateral thickness of the self-adhesive label strip... When performing multi-point thickness testing, the cylinder 302 can be controlled to operate. The cylinder 302 will push the sliding plate 601 to drive the synchronization bar 6 to slide inside the U-shaped bar 3. The synchronization bar 6 combines the two sets of sliding plates 601, so the sliding plate 601 will synchronously control the laser emitter 4 and the laser receiver 5 to move synchronously, thereby ensuring accurate testing of the thickness of the self-adhesive strip. At the same time, the use of the cylinder 302 can control the lateral movement of the laser emitter 4 and the laser receiver. The electric lifting rod 2 will control the up and down movement of the U-shaped bar 3, and thus control the up and down movement of the laser emitter 4 and the laser receiver, so that self-adhesive strips of different widths and heights can be sampled for inspection.

[0029] Example 2

[0030] Please see Figure 3 , Figure 4 and Figure 5 Based on Example 1, the sliding plate 601 and the sliding port 305 are used in combination to ensure that the sliding plate 601 stably drives the laser receiver 5 and the laser emitter 4 to move.

[0031] Specifically, the inner wall of the U-shaped strip 3 has an adjustment port 304 that communicates with the inside of the sliding port 305. Both ends of the U-shaped strip 3 pass through the inside of the adjustment port 304. Each sliding plate 601 is slidably disposed in the corresponding sliding port 305. Each end face of the sliding plate 601 is fixed with a connecting rod 602 that passes through the port of the sliding port 305. The other end of each connecting rod 602 is fixed with a mounting plate 603 that connects with the end face of the U-shaped strip 3. The mounting plate 603 is connected to the laser receiver 5 and the laser emitter 4 respectively by bolts.

[0032] The operation process of this embodiment is as follows: by using the connecting rod 602 and the mounting plate 603, the sliding plate 601 can be assembled and connected with the laser receiver and the laser emitter 4. Thus, when the sliding plate 601 moves, it will drive the laser receiver 5 and the laser emitter 4 to move through the connecting rod 602 and the mounting plate 603. The synchronization bar 6 slides inside the U-shaped bar 3. When the sliding plate 601 is in the sliding port 305, the sliding port 305 limits the sliding plate 601, ensuring that the sliding plate 601 can move stably.

[0033] Example 3

[0034] Please see Figure 2 and Figure 3 Based on Example 1, the lifting height of the U-shaped strip 3 is limited by the circular plate 103.

[0035] Specifically, a positioning rod 102 is fixed on the upper surface of the base plate 1 located to the right of the electric lifting rod 2. A circular plate 103 is provided on the upper surface of the positioning rod 102. A screw hole 105 is opened in the middle of the upper surface of the positioning rod 102. A screw 104 is fixed on the lower surface of the circular plate 103, which is screwed in the screw hole 105. A positioning plate 301 is bolted to the surface wall of the U-shaped strip 3. The upper surface of the positioning plate 301 is sleeved on the positioning rod 102 through the positioning hole 303, and the diameter of the positioning hole 303 is smaller than the diameter of the circular plate 103.

[0036] The operation process of this embodiment is as follows: When the U-shaped bar 3 moves up and down, the U-shaped bar 3 controls the positioning plate 301 to slide up and down along the positioning rod 102 through the positioning hole 303. Therefore, the positioning rod 102 limits the movement of the U-shaped bar 3, and the movement of the U-shaped bar 3 is stable. The positioning plate 301 is limited by the circular plate 103, thereby limiting the lifting height of the U-shaped bar 3. At the same time, the circular plate 103 is rotated, thereby controlling the screw 104 to turn out in the screw hole 105. Thus, the circular plate 103 does not disassemble the positioning plate 301. Therefore, after the electric lifting rod 2 and the U-shaped bar 3 are separated, the U-shaped bar 3 can be moved upward.
