Description

Technical Field

[0001] This utility model belongs to the field of self-adhesive label testing technology, specifically relating to a self-adhesive label viscosity testing device. Background Technology

[0002] Labels are tools that are affixed to items to display accurate information about them. Different types of labels are used depending on the application scenario. For example, self-adhesive labels offer advantages such as not requiring glue, paste, or water, being pollution-free, and saving labeling time. Modern self-adhesive labels undergo multiple testing processes after processing, including viscosity testing. Viscosity testing is divided into three types: initial tack, holding power, and peel strength. When testing the initial tack of self-adhesive labels, a specialized inclined roller ball device is used. The label to be tested is placed on the device, and then a roller ball is placed on the device surface. Utilizing the device's slope, the roller ball rolls along the surface until it reaches the adhesive layer of the self-adhesive label. The test is then conducted by observing whether the roller ball directly adheres to the adhesive layer of the self-adhesive label.

[0003] Existing inclined ball rolling equipment can test the adhesiveness of self-adhesive label adhesive layers, but there are certain problems in actual use. Specifically, the existing ball bearings have high requirements for specifications and precision. When the ball bearings cannot be attached to the adhesive layer, they roll directly into the collection chamber below. This step causes the ball bearings to collide with the equipment housing, affecting the precision of the ball bearings themselves. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0006] A self-adhesive label viscosity testing device includes a base and a viscosity testing platform. The viscosity testing platform is installed on the base and locks the position of the ball and the self-adhesive label. It assists the ball in passing through the adhesive layer of the self-adhesive label. A receiving mechanism is installed on the viscosity testing platform to shorten the rolling distance of the ball and reduce the impact force of the ball.

[0007] As a preferred technical solution of this utility model, the receiving mechanism includes a guiding component and a collecting component. The guiding component is installed on the viscosity testing stage, guides the rolling balls on the viscosity testing stage, and controls the rolling distance of the balls. A collecting component for accurately receiving the balls is provided on the upper surface of the base and below the guiding component.

[0008] As a preferred technical solution of this utility model, the guiding component includes a sliding block, a guide rod, and a squeezing screw. Sliding grooves are provided on both sides of the viscosity testing platform, and sliding blocks are slidably installed in the sliding grooves. A guide rod is installed between the sliding blocks to guide the balls to roll into the collecting component and control the rolling distance of the balls. The side of the guide rod that contacts the balls is covered with a buffer rubber layer. A squeezing screw is threaded on the side wall of one set of sliding blocks. The end of the squeezing screw makes squeezing contact with the viscosity testing platform to lock the position of the guide rod.

[0009] As a preferred technical solution of this utility model, the collection component includes a collection chamber, a receiving element, and a sliding seat. The base is provided with a collection chamber for collecting the balls, and a sliding seat is installed at the bottom of the collection chamber. The sliding seat slides along the base to adjust the position of the collection chamber. The collection chamber is provided with a receiving element that receives the balls and reduces the impact force of the balls.

[0010] As a preferred technical solution of this utility model, the receiving component includes a receiving layer. The receiving layer is provided in the collection chamber. The receiving layer adopts a rectangular sponge filling layer structure, which reduces the impact force of the ball.

[0011] As a preferred embodiment of this utility model, the receiving component includes a buffer layer, which is disposed in the collection chamber. The buffer layer has an inclined portion that guides the rolling of the balls, and the buffer layer adopts a sponge-filled structure.

[0012] As a preferred embodiment of this utility model, the viscosity testing station includes a testing station, a limiting guide rod, and an adjusting block. A rotating bracket is mounted on the base, and the testing station is mounted on the rotating bracket. A limiting guide rod is mounted on one end of the testing station, and an adjusting block is mounted on the limiting guide rod. The adjusting block slides along the length of the limiting guide rod. An adjusting screw is threaded onto the adjusting block, and a limiting frame is mounted on the end of the adjusting screw. The limiting frame has a placement groove for placing balls and positioning the rolling trajectory of the balls.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a viscosity testing platform and a receiving mechanism. The self-adhesive label is placed on the surface of the testing platform, ensuring the adhesive layer of the label is positioned on the trajectory of the ball bearing. The viscosity of the label is measured by observing whether the ball bearing is properly attached to the adhesive layer as it rolls down and directly contacts the adhesive layer. The guide rod effectively shortens the rolling distance of the ball bearing, reducing the impact force and guiding it to its correct trajectory, allowing it to accurately enter the collection chamber. The receiving mechanism further reduces the impact force, preventing direct collisions between the ball bearing and the collection chamber housing that could cause dents or other defects. This ensures the accurate use of the ball bearing during subsequent testing. Attached Figure Description

[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0023] Example 1 like Figure 1 The diagram shows the structure of the self-adhesive label viscosity testing device in this embodiment. In actual use, this device guides and collects balls not attached to the adhesive layer, shortening the ball's rolling path, reducing the impact force when the ball collides with the housing, and ensuring the stability of the balls. The testing device includes a base 1 and a viscosity testing platform 2. The viscosity testing platform 2 is installed at the top of the base 1, providing stable support for its establishment. The self-adhesive label is placed on the surface of the viscosity testing platform 2, ensuring the adhesive layer of the label faces upwards, facilitating direct contact between the ball and the adhesive layer as it rolls along the surface of the platform, thus determining the initial tack of the self-adhesive label. A receiving mechanism 3 is installed on the viscosity testing platform 2 to control the rolling path of balls not attached to the adhesive layer. The receiving mechanism 3 shortens the rolling path of the balls, assisting in the stable collection of the balls.

[0024] As attached Figure 2The diagram shows the structure of the viscosity testing station 2 in this embodiment. The viscosity testing station 2 includes a testing station 21, a limiting guide rod 22, and an adjusting block 23. The testing station 21 is mounted on the base 1. A limiting guide rod 22 is installed on one end of the testing station 21, and an adjusting block 23 is installed on the limiting guide rod 22. The adjusting block 23 slides along the length of the limiting guide rod 22. An adjusting screw 25 is threaded onto the adjusting block 23, and a limiting frame 24 is installed at the end of the adjusting screw 25. The limiting frame 24 is attached to the upper surface of the testing station 21. A ball bearing placement groove is provided inside the limiting frame 24. The ball bearings are placed in the placement groove. By pushing the adjusting block 23, the position of the limiting frame 24 is moved, ensuring that the ball bearings in the placement groove pass over the adhesive layer of the self-adhesive label on the testing station 21 when sliding along the surface of the testing station 21. Then, by pressing the adjusting screw 25, the overall angle of the limiting frame 24 is raised, and the limiting frame 24 releases the limit on the ball. At this time, the ball rolls along the surface of the testing table 21 under the action of gravity and comes into contact with the adhesive layer. The initial tack of the self-adhesive label is tested by observing whether the ball is attached to the adhesive layer. The base 1 is equipped with a rotating bracket 26 for adjusting the overall angle of the testing table 21. The rotating bracket 26 is mainly composed of a support frame, a fixing plate and a fixing screw. The support frame is installed on the upper surface of the base 1 and the fixing plate is installed below the testing table 21. The support frame and the fixing plate are provided with a threaded groove. The fixing screw is installed in the threaded groove and a nut is provided at the end of the fixing screw. By squeezing the fixing screw and the nut, the angle of the fixing plate and the support frame is controlled and adjusted to adjust the overall angle of the testing table 21.

[0025] It is worth noting that the upper surface of the testing table 21 is provided with a scale groove. The operator can make precise adjustments to the distance between the self-adhesive label and the ball bearing according to the use of the scale groove, so as to ensure that the ball bearing rolls over the adhesive layer under specific distance and slope conditions. The threaded setting on the adjusting screw 25 allows the position of the limit frame 24 on the testing table 21 to be adjusted by rotating the adjusting screw 25, thereby achieving the purpose of controlling the position of the limit frame 24.

[0026] As attached Figure 3As shown, this is a schematic diagram of the receiving mechanism 3 in this embodiment. The receiving mechanism 3 includes a sliding block 31, a guide rod 32, and a squeezing screw 33. Sliding grooves are symmetrically provided on both sides of the viscosity testing platform 2. Sliding blocks 31 are slidably installed in the sliding grooves, and guide rods 32 are installed between the sliding blocks 31. The guide rods 32 guide the balls to shift and roll to one side for easy subsequent collection. The side of the guide rod 32 that contacts the balls is covered with a buffer rubber layer. A squeezing screw 33 is threaded onto the side wall of one set of sliding blocks 31. The rotation of the squeezing screw 33 causes its end to squeeze the viscosity testing platform 2, thus adjusting the overall position and height of the guide rod 32. The base 1 is locked, and a collection chamber 34 is provided on the upper surface of the base 1. The collection chamber 34 is located below the inclined end of the guide rod 32. A sliding seat 36 is installed at the bottom of the collection chamber 34. The sliding seat 36 slides along the surface of the base 1. The horizontal position of the collection chamber 34 is adjusted according to the position of the guide rod 32, so that the balls guided by the guide rod 32 can accurately enter the collection chamber 34. The collection chamber 34 is filled with a receiving member 35. The receiving member 35 receives the balls, and the material properties of the receiving member 35 prevent the balls from directly colliding rigidly with the collection chamber 34. This completes the safe collection of balls that are not attached to the surface of the adhesive layer.

[0027] It is worth noting that in this embodiment, the sliding block 31, the guide rod 32 and the extrusion screw 33 form a guiding assembly that shortens the rolling resistance of the balls and reduces the impact force of the balls, and the collection chamber 34, the receiving member 35 and the sliding seat 36 form a ball collection assembly.

[0028] As attached Figure 4 As shown, it is a schematic diagram of the structure of the receiving device 35 in this embodiment. The receiving device 35 includes a receiving layer 351, which is a rectangular sponge filling layer structure. When the ball rolls down along the guide rod 32 into the collection chamber 34, the receiving layer 351 receives the ball. The characteristics of the receiving layer 351 itself can reduce the impact force of the ball and complete the stable collection of the ball.

[0029] Example 2 As attached Figure 5 As shown, it is a structural schematic diagram of the receiving device 35 in this embodiment. The difference between this embodiment and embodiment 1 is that the receiving device 35 in this embodiment includes a buffer layer 352. The buffer layer 352 adopts a sponge filling layer structure. An inclined guide portion is provided on the buffer layer 352. After the ball falls from the guide rod 32, it continues to roll along the guide portion of the buffer layer 352 until it collides with the end face of the buffer layer 352, thereby assisting the ball to complete a more stable collection.

[0030] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
