[0002] In the printing and packaging industry, the accurate determination of adhesive parameters directly affects the bonding strength, durability, and production efficiency of packaging materials. Currently, experimental testing of adhesive parameters (such as adhesive viscosity, curing temperature, and lamination pressure) mainly relies on traditional equipment and methods.

[0003] Existing technologies mainly employ manual experimental methods. Determining adhesive parameters usually requires numerous repetitive experiments, relying on manual adjustment of parameters such as adhesive specifications, pressure, and temperature. This process is cumbersome and prone to introducing human error. Summary of the Invention

[0004] The technical problem to be solved by this application is to provide an experimental apparatus for determining adhesive parameters in printing and packaging, which can reduce human error and improve the reliability of adhesive parameter determination.

[0005] This application provides an experimental apparatus for determining adhesive parameters in printing and packaging, comprising:

[0006] A base having an adhesive application groove and a composite groove;

[0007] The glue scraping mechanism includes a first mounting bracket slidably disposed on the base, a first linear reciprocating drive assembly disposed on the first mounting bracket, and a glue scraping component disposed on the execution end of the first linear reciprocating drive assembly, wherein the glue scraping component is adapted to the glue brushing groove.

[0008] The composite mechanism includes a second mounting bracket disposed on the base, a second linear reciprocating drive assembly disposed on the second mounting bracket, and a composite component disposed on the execution end of the second linear reciprocating drive assembly, wherein the composite component is adapted to the composite groove;

[0009] A linear reciprocating drive mechanism is used to drive the glue scraping mechanism to reciprocate along the glue application groove.

[0010] Optionally, the glue-applying groove has a glue-applying area, and the glue-applying area has a plurality of glue-applying holes distributed in a dispersed manner.

[0012] Optionally, the base includes a substrate, a platform disposed on the substrate, and two guide plates disposed on the substrate and located on both sides of the platform. Two guide grooves are formed between the two guide plates and the platform. The two ends of the first mounting bracket are slidably disposed in the two guide grooves respectively. The glue application groove, the composite groove, and the overflow groove are located on the top of the platform.

[0013] Optionally, the first linear reciprocating drive assembly includes a first linear driver fixedly mounted on the first mounting bracket and a first guide frame slidably mounted on the first mounting bracket, with the scraper disposed at the bottom of the first guide frame.

Then, the first linear reciprocating drive assembly adjusts the scraper to maintain a set height with the adhesive application tank. The linear reciprocating drive mechanism then drives the scraper to scrape off excess adhesive and spread it evenly. Next, a piece of packaging paper is placed in the adhesive application tank, and the packaging paper is rolled by a roller operated manually. The packaging paper is then removed and placed in the lamination tank with the adhesive side facing up.

Detailed Implementation

[0025] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0026] like Figure 1-3 As shown, this application provides an experimental apparatus for determining adhesive parameters in printing and packaging, comprising: a base 100, a scraping mechanism 200, a composite mechanism 300, and a linear reciprocating drive mechanism 400; wherein, the base 100 has a brushing groove 121 and a composite groove 122; the scraping mechanism 200 includes a first mounting bracket 210 slidably disposed on the base 100, a first linear reciprocating drive assembly 220 disposed on the first mounting bracket 210, and a [missing information - likely a component or component] disposed on the first linear reciprocating drive assembly 220. The scraper 230 on the execution end is adapted to the glue application groove 121; the composite mechanism 300 includes a second mounting bracket 310 disposed on the base 100, a second linear reciprocating drive assembly 320 disposed on the second mounting bracket 310, and a composite component 330 disposed on the execution end of the second linear reciprocating drive assembly 320, the composite component 330 being adapted to the composite groove 122; the linear reciprocating drive mechanism 400 is used to drive the scraper mechanism 200 to reciprocate along the glue application groove 121.

[0027] Compared with the prior art, the experimental apparatus for determining adhesive parameters in printing and packaging provided in this application first involves manually applying adhesive to the glue application tank 121. Then, the first linear reciprocating drive assembly 220 adjusts the glue scraper 230 to maintain a set height with the glue application tank 121. Next, the linear reciprocating drive mechanism 400 drives the glue scraper mechanism 200 to scrape off excess adhesive and spread it evenly. Then, a piece of packaging paper is placed in the glue application tank 121 and rolled by a roller manually. The packaging paper is then removed and placed in the lamination tank 122 with the adhesive side facing up. Another piece of packaging paper is then placed in the lamination tank 122. The second linear reciprocating drive assembly 320 then drives the lamination assembly 330 to press the two pieces of packaging paper together with a set pressure for a set duration. Afterward, the laminated packaging paper is removed for further testing. The glue thickness, open time, lamination pressure, lamination time, and other parameters can be adjusted, and the adhesive can be changed. The above operation can be repeated to obtain multiple laminated packaging paper pieces, thereby quickly determining the adhesive parameters. This experimental setup eliminates the need for manual intervention in adjusting parameters such as adhesive thickness, open time, lamination pressure, and lamination time, thereby reducing human error and improving the reliability of adhesive parameter determination.

[0028] In one possible implementation, such as Figure 3As shown, the glue application groove 121 has a glue application area, and the glue application area has multiple glue-attaching holes 123 distributed in a dispersed manner. Specifically, the glue application area is used to define the position where the packaging paper needs to be glued. The glue application area is concentrated on one side of the glue application groove 121 and is distributed in a rectangular array. Since the surface of the glue application groove 121 is relatively smooth, the multiple glue-attaching holes 123 in the glue application area can adhere glue, which helps to improve the uniformity of glue application.

[0029] In one possible implementation, such as Figure 3 As shown, the base 100 also has an overflow groove 124 located at one end of the glue application groove 121, which is used to store excess glue scraped off by the glue scraper 230. Specifically, when scraping glue, the glue scraper 230 scrapes excess glue into the overflow groove 124 to prevent glue from overflowing and contaminating the operating surface, thus avoiding mechanical failure.

[0030] In one possible implementation, the scraper 230 includes a first connecting rod 231 fixedly disposed at the bottom of the first guide frame 222 and a scraper 232 fixedly disposed at the bottom end of the first connecting rod 231. The end of the first connecting rod 231 may have threads for screwing into the bottom of the first guide frame 222 and may also be screwed into a nut for fastening.

[0031] In one possible implementation, the composite component 330 includes a second connecting rod 331 fixedly disposed at the bottom of the second guide frame 322 and a pressure block 332 fixedly disposed at the bottom end of the second connecting rod 331. The end of the second connecting rod 331 may have threads for screwing into the bottom of the second guide frame 322 and may also be screwed into a nut for fastening.

[0032] In one possible implementation, the base 100 includes a substrate 110, a base 120 disposed on the substrate 110, and two guide plates 130 disposed on the substrate 110 and located on both sides of the base 120. Two guide grooves 140 are formed between the two guide plates 130 and the base 120. The two ends of the first mounting bracket 210 are slidably disposed within the two guide grooves 140. An adhesive application groove 121, a composite groove 122, and an overflow groove 124 are located on the top of the base 120. Specifically, the circumferential area of ​​the base 120 is smaller than the unfolded area of ​​the substrate 110. The base 120 can be fixed to the top of the substrate 110 by bolts or welding, or it can be integrally machined. The two guide plates 130 can be fixed to the top sides of the substrate 110 by bolts or welding, or they can be integrally machined, forming corresponding guide grooves 140 during processing. The cross-sectional shape of the guide groove 140 can be convex or L-shaped, used to limit the linear movement of the first mounting bracket 210 and the sliding bracket 410. In addition, the top surface of the base 120 is machined by turning to form a glue-applying groove 121, a composite groove 122 and a glue overflow groove 124, and a glue-attaching hole 123 is formed by drilling.

[0033] In one possible implementation, the first linear reciprocating drive assembly 220 includes a first linear driver 221 fixedly mounted on the first mounting bracket 210, a first guide frame 222 slidably mounted on the first mounting bracket 210, and a scraper 230 disposed at the bottom of the first guide frame 222. Specifically, the first mounting bracket 210 is shaped like a gantry, spanning the base 120, with its two ends slidably disposed within two guide grooves 140. The first linear driver 221 is vertically fixed to the top of the first mounting bracket 210, and its actuating end passes through the first mounting bracket 210 and is connected to the scraper 230. In use, the height of the scraper 230 is adjusted by the first linear driver 221, thereby controlling the scraping thickness.

[0034] In one possible implementation, the first linear actuator 221 includes one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder. The optimal drive scheme can be quickly matched by clearly defining load, speed, accuracy, and environmental limitations. In some cases, hybrid drives (such as pneumatic-electric hybrid cylinders) or customized designs (such as explosion-proof hydraulic cylinders) may be considered.

[0035] In one possible implementation, the second linear reciprocating drive assembly 320 includes a second linear driver 321 fixedly mounted on the second mounting bracket 310, a second guide frame 322 slidably mounted on the second mounting bracket 310, and a composite member 330 disposed at the bottom of the second guide frame 322. Specifically, the second mounting bracket 310 is shaped like a gantry, spanning the base 120, with its two ends fixedly disposed within two guide slots 140. The second linear driver 321 is vertically fixed to the top of the second mounting bracket 310, with its actuating end penetrating the second mounting bracket 310 and connected to the composite member 330. In use, the height of the composite member 330 is adjusted by the second linear driver 321 to control the composite pressure, and the composite duration is set by the second linear driver 321.

[0036] In one possible implementation, the second linear actuator 321 includes one of an electric cylinder, a pneumatic cylinder, and a hydraulic cylinder. The optimal drive scheme can be quickly matched by clearly defining load, speed, accuracy, and environmental limitations. In some cases, hybrid drives (such as pneumatic-electric hybrid cylinders) or customized designs (such as explosion-proof hydraulic cylinders) may be considered.

[0037] In one possible implementation, the linear reciprocating drive mechanism 400 includes a sliding frame 410 that slides with the base 100, a drive motor 420 fixedly mounted on the base 100, and a lead screw 430 that is drively connected to the output shaft of the drive motor 420. The lead screw 430 is threaded to the sliding frame 410, and the sliding frame 410 is fixedly connected to the first mounting bracket 210. Specifically, the sliding frame 410 is shaped like a U-shape, and its two ends are slidably disposed in two guide grooves 140. The drive motor 420 is fixed on the base plate 110. The drive motor 420 causes the lead screw 430 to rotate, driving the sliding frame 410 and the glue scraping mechanism 200 to reciprocate along the guide grooves 140, thereby enabling the glue scraper 230 to scrape off excess glue in the glue application groove 121 and spread the glue evenly.

[0038] In one possible implementation, the experimental apparatus for determining the adhesive parameters of printed packaging further includes an electric heating module (not shown), which is disposed within the base 100 and below the composite tank 122. The heating temperature is adjusted via the electric heating module to accurately obtain the suitable adhesive temperature for the packaging paper. The electric heating module can employ resistance wire heating, PTC heating, flexible film heating, etc.

[0039] In one possible implementation, the electric heating module is located within the composite component 330. This allows for heating of both the top and bottom sides of the packaging paper within the composite tank 122, shortening the heating time and improving experimental efficiency.

[0040] The experimental apparatus for determining adhesive parameters in printing and packaging provided in this embodiment also includes a control cabinet 500 and a switch 600 respectively disposed on both sides of the base 100.
