Description

Technical Field

[0001] This utility model relates to the field of printing material adhesion strength testing technology, specifically a device for testing the adhesion strength of printing materials on corrugated cardboard surfaces. Background Technology

[0002] Corrugated cardboard surface printing materials can firmly cover the surface of objects, serving as protection, decoration, marking, and other special purposes. The adhesion strength of printing materials refers to the ability of the paint coating to bond with the surface of the coated object or between the coatings, and is an important technical indicator of the quality of printing materials.

[0003] Commonly used adhesion testing methods include the cross-cut test, the fork test, and the pull-off test. The existing testing method is as follows: First, the printed coating is easily cut open with a cutting disc, and the printed material on the corrugated cardboard surface is scraped. Then, a soft brush is used to gently sweep backward and forward several times along each diagonal of the coating grid to remove loose paint debris. A section of adhesive tape is then pulled out at a uniform speed, and the adhesive tape is flattened above the grid area with the fingers. Finally, immediately after tearing off the adhesive tape, the cut area of ​​the test coating is carefully inspected visually or with a magnifying glass in a well-lit environment, and the results are rated according to the standard and recorded.

[0004] However, existing printing material adhesion strength testing devices typically have a cutting disc fixed to a frame. After prolonged use, the cutting disc may wear down, and this fixed design prevents quick disassembly and replacement, resulting in a short overall device lifespan. Therefore, this does not meet current requirements. To address this, we propose a new device for testing the adhesion strength of printing materials on corrugated cardboard surfaces. Utility Model Content

[0005] The purpose of this utility model is to provide a device for testing the adhesion strength of printed materials on corrugated cardboard, in order to solve the problem that the cutting disc in the printing material adhesion strength testing device mentioned in the background art is generally fixed on a fixed frame. After long-term use, the cutting disc may wear out. However, the fixed cutting disc makes it impossible to quickly disassemble and replace the whole device, resulting in a short service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a device for testing the adhesion strength of printed materials on the surface of corrugated cardboard, comprising a testing device platform, slide rails on both the front and rear sides of the upper end of the testing device platform, slide bars on the upper end of the slide rails, a movable platform fixedly connected to the upper end of the two slide bars, and snap-fit ​​components fixedly connected to the four corners of the upper end of the movable platform, with corrugated cardboard snapped between the four snap-fit ​​components;

[0007] A fixing frame is fixedly connected to the rear side of the upper end of the testing device platform. A connecting column is provided at the lower end of the fixing frame. A plug-in plate is fixedly connected to the lower end of the connecting column. Multiple plug-in slots are arranged at the lower end of the plug-in plate. Cutting components are horizontally inserted into the plug-in slots.

[0008] Preferably, the snap-fit ​​component includes connecting blocks fixedly connected to the four corners of the upper end of the movable platform, a connecting plate fixedly connected to one side of the connecting block, and a snap-fit ​​ring fixedly connected to the lower end of the connecting plate, wherein the cross-section of the snap-fit ​​ring is an elliptical ring structure.

[0009] Preferably, the cutting component includes a connector plate inserted into the connector slot, a cutting blade plate is fixedly connected to the lower end of the connector plate, and a plurality of snap-fit ​​slots are arranged on the upper end surface of the connector plate.

[0010] Preferably, the cross-section of the insertion slot and the insertion plate is T-shaped, and the lower end of the cutting blade is serrated.

[0011] Preferably, the upper surface inside the insertion slot is provided with a plurality of fixing cavities, and a limiting ring is fixedly connected inside the fixing cavity, with the lower end of the limiting ring being engaged in the insertion slot.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model allows the entire plug-in plate to be manually pulled out laterally from the plug-in slot. Due to the elasticity of the limiting ring itself, it can be disengaged from the inside of the snap-fit ​​slot, thereby allowing the multiple limiting rings to no longer limit the plug-in plate, and allowing the entire cutting blade to be disengaged from the plug-in slot. This setting and operation allows the entire cutting component to be disassembled and replaced.

[0014] 2. By setting the cross-section of the snap-fit ​​ring as a ring structure, this utility model further improves the elasticity of the snap-fit ​​ring. The elasticity of the snap-fit ​​ring and the elasticity of the connecting plate enable the corrugated cardboard to be snapped between the four snap-fit ​​parts, thereby positioning the entire corrugated cardboard at the upper end of the movable table.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 4 An embodiment of this utility model is provided: a device for testing the adhesion strength of printing materials on the surface of corrugated cardboard, including a testing device platform 1. The front and rear sides of the upper end of the testing device platform 1 are provided with slide rails 2. The upper end of the slide rails 2 is provided with slide bars 11. The upper ends of the two slide bars 11 are fixedly connected to a movable platform 3. The four corners of the upper end of the movable platform 3 are fixedly connected with snap-fit ​​components 6. Corrugated cardboard 4 is snapped between the four snap-fit ​​components 6.

[0022] A fixing frame 5 is fixedly connected to the rear side of the upper end of the testing device platform 1. A connecting column 12 is provided at the lower end of the fixing frame 5. A plug-in plate 8 is fixedly connected to the lower end of the connecting column 12. Multiple plug-in slots 13 are arranged at the lower end of the plug-in plate 8. A cutting component 7 is horizontally inserted into the plug-in slot 13.

[0023] The snap-fit ​​component 6 includes four connecting blocks 601 fixedly connected to the four corners of the upper end of the movable platform 3. A connecting plate 602 is fixedly connected to one side of the connecting block 601. A snap-fit ​​ring 603 is fixedly connected to the lower end of the connecting plate 602. The cross-section of the snap-fit ​​ring 603 is set as an elliptical ring structure.

[0024] The insertion slot 13 and the cutting surface of the insertion plate 702 are designed as a T-shaped structure, so the insertion plate 702 can be inserted horizontally into the insertion slot 13. This design allows the insertion plate 702 to be positioned at the lower end of the insertion plate 8, thus making it difficult for the insertion plate 702 to come out from the lower end of the insertion plate 8. The lower end of the cutting blade 701 is serrated, so that the cutting blade 701 can perform a scraping operation on the surface of the corrugated cardboard 4.

[0025] The cutting component 7 includes a plug plate 702 inserted into the plug groove 13. A cutting blade 701 is fixedly connected to the lower end of the plug plate 702. A plurality of snap-fit ​​grooves 703 are arranged on the upper end surface of the plug plate 702. A plurality of fixing cavities 10 are arranged on the upper end surface inside the plug groove 13. A limit ring 9 is fixedly connected inside the fixing cavity 10. The lower end of the limit ring 9 is snapped into the snap-fit ​​groove 703.

[0026] In use, the entire corrugated cardboard 4 is first snapped between the four snap-fit ​​parts 6 at the top of the movable table 3. The four snap-fit ​​parts 6 can snap and fix the corrugated cardboard 4. The connecting plate 602 and the connecting block 601 are connected by elastic metal, which makes one end of the connecting plate 602 elastic. Then, the snap-fit ​​ring 603 at the lower end of the connecting plate 602 is also made of elastic metal, and the cross-section of the snap-fit ​​ring 603 is set as a ring structure. This ring structure further improves the elasticity of the snap-fit ​​ring 603. The elasticity of the snap-fit ​​ring 603 and the elasticity of the connecting plate 602 enable the entire corrugated cardboard 4 to be snapped between the four snap-fit ​​parts 6, thereby making the entire corrugated cardboard 4 snapped and positioned at the top of the movable table 3.

[0027] Next, the entire cutting component 7 is horizontally inserted into the insertion groove 13 at the lower end of the insertion plate 8. The cutting surface of the insertion plate 702 is designed as a T-shaped structure, which allows the insertion plate 702 to be horizontally inserted into the insertion groove 13. Multiple fixing cavities 10 are arranged at the bottom of the insertion groove 13. A limiting ring 9 is fixedly connected inside the fixing cavity 10. When the entire cutting component 7 is inserted into the insertion groove 13, the lower end of the limiting ring 9 is engaged in the engaging groove 703 at the upper end of the insertion plate 702. This arrangement allows the entire insertion plate 702 to be engaged and fixed inside the insertion groove 13.

[0028] When the lower end of the overall cutting component 7 shows signs of wear after prolonged use, it needs to be replaced. At this time, simply manually pull the overall connector plate 702 out horizontally from the connector slot 13. Due to the elasticity of the limiting ring 9 itself, it can disengage from the inside of the snap-fit ​​slot 703, thereby allowing the multiple limiting rings 9 to no longer limit the connector plate 702, so that the overall cutting blade 701 can disengage from the connector slot 13. This setting and operation allows the overall cutting component 7 to be disassembled and replaced.

[0029] When the entire corrugated cardboard 4 is snapped and positioned at the upper end of the movable table 3, and when the cutting component 7 is snapped and fixed at the lower end of the insertion plate 8, the entire movable table 3 is manually moved laterally at the upper end of the detection device table 1. Then, the multiple cutting components 7 at the lower end of the insertion plate 8 can scrape the surface of the corrugated cardboard 4, so that the printing material on the surface of the corrugated cardboard 4 can be detached from its surface, thereby enabling the detection device to detect the detached printing material. The detection method is the same as that in the existing technology and has been described in the background art. Therefore, the detection method will not be described again in this embodiment.

[0030] In the above configuration, the cutting component 7 and the insertion plate 8 enable the cutting component 7 to be quickly disassembled and installed, and extend the service life of the cutting component 7 at the lower end of the insertion plate 8. By fixing the snap-fit ​​component 6 to the upper end of the movable table 3, the snap-fit ​​component 6 can snap the corrugated cardboard 4, thereby achieving the limiting and fixing of the corrugated cardboard 4.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
