Description

Technical Field

[0001] This utility model relates to the technical field of cardboard box testing devices, and in particular to a cardboard box adhesive force testing device. Background Technology

[0002] In the transportation and storage of liquid condiments such as soy sauce, the adhesive strength of the packaging cartons is a key factor affecting product safety and quality stability. Insufficient adhesive strength can lead to cracking, deformation, or even leakage of contents during transportation, causing economic losses and damage to brand reputation. Therefore, accurate and efficient testing of carton adhesive strength is crucial for the quality control of carton packaging.

[0003] Currently, the commonly used methods for testing the adhesive strength of cartons in the industry mainly include manual peeling, mechanical insertion, and tape peeling. Manual peeling: Operators manually peel the adhesive surfaces of the cartons, judging the adhesive strength based on experience. This method is highly subjective, lacks quantitative standards, and is greatly affected by the operator's skill level, making it difficult to guarantee consistency and accuracy. Mechanical insertion: A clamp is inserted into the gap inside the carton, and then a horizontal pulling force is applied to measure the separation force of the adhesive surfaces. Although this method is more objective than manual peeling, there is a risk that the clamp may cause additional damage to the edges of the carton, affecting the test results; moreover, the direction of force between the clamp and the carton is difficult to control precisely during the test, leading to large data fluctuations; and the adaptability to different carton sizes varies greatly, requiring frequent adjustments to the clamp dimensions. Tape peeling: Tape is applied to the adhesive surfaces of the carton and then quickly peeled off. The adhesive strength is assessed by observing the tape residue. Although this method is simple to operate, it is only suitable for qualitative analysis and cannot provide accurate mechanical data, and it is greatly affected by the tape material and peeling speed.

If the terms "first" and "second" are used, they are merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or the order of the indicated technical features.

[0022] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0023] Reference Figures 1 to 3 This utility model provides a carton adhesive force testing device, including an adsorption mechanism and a testing mechanism. The adsorption mechanism includes an adsorption component 100 and an air source communication component 200, which are connected to each other. The adsorption component 100 can provide negative pressure suction to adsorb the surface of the carton. The testing mechanism is connected to the adsorption component 100 and includes a tensile detector 300, which is used to detect the tensile force between the adsorption component 100 and the testing mechanism. Specifically, the tensile detector 300 is a tensile testing instrument that can display the tensile force detection value in real time.

[0024] Specifically, the suction component 100 is attached to the surface of the carton to be tested. Then, the detection mechanism can pull the suction component 100 horizontally, generating a pulling force on the carton surface. Since the suction component 100 is only subjected to gravity, the pulling force of the detection mechanism, and the pulling force of the carton surface, when the suction component 100 is in a relatively static state, the pulling force between the detection mechanism and the suction component 100, and the pulling force between the suction component 100 and the carton surface are equal. At this time, the pulling force detection value of the tension detector 300 is the pulling force value between the suction component 100 and the carton surface. Alternatively, the detection mechanism can pull the suction component 100 vertically, generating a pulling force on the carton surface. When the suction component 100 is in a relatively static state, the pulling force value between the suction component 100 and the carton surface can be obtained by tareing the pulling force detection value of the tension detector 300 and subtracting the weight of the suction component 100 itself. By applying different tensile forces to the cardboard box using testing and adsorption mechanisms, it is possible to test whether the cardboard box can withstand the tensile force and thus determine its tensile strength.

[0025] In some embodiments, reference is made to Figure 1 The suction assembly 100 includes a vacuum generator 140, which is connected to an external high-pressure air source through an air source connection assembly 200. The external high-pressure air source is used as a power source to drive the vacuum generator 140 to perform a negative pressure operation, and generate negative pressure suction in the suction assembly 100, so as to adsorb the suction assembly 100 onto the surface of the packaging carton.

[0026] It is understood that in some other embodiments, the suction component 100 is connected to a vacuum pump (not shown) through the air source connection component 200. The negative pressure generated by the vacuum pump is transmitted to the suction component 100 through the air source connection component 200, so that the suction component 100 generates negative pressure suction, thereby adsorbing the suction component 100 onto the surface of the packaging carton.

[0027] Compared to traditional inspection methods such as inserting mechanical tools into the cardboard box or manually peeling it off, this application utilizes a suction component 100 to adhere to the surface of the cardboard box, combined with a tensile force detector 300 to record tensile force data in real time. This enables a quantitative assessment of the cardboard box's adhesive strength, improving the objectivity of the adhesive force test and solving the problems of accuracy and efficiency associated with traditional inspection methods. The suction component 100 only contacts the surface of the cardboard box, without needing to be inserted into the box, avoiding the squeezing or tearing of the adhesive edges by mechanical clamps or hooks, ensuring that the test data accurately reflects the bonding strength between the adhesive and the cardboard. By adhering to the cardboard box surface with the suction component 100, the connection between the inspection device and the cardboard box is achieved, enabling simultaneous "adsorption" and "measurement," shortening the single inspection time, making operation convenient and quick, improving inspection efficiency, and suitable for rapid sampling inspection on production lines. The suction component 100 can closely fit the curved or uneven surface of the cardboard box, avoiding measurement errors caused by dimensional mismatches in traditional rigid clamps.

[0028] According to some embodiments of this application, refer to Figures 1 to 3 The testing mechanism includes a connecting component 400, which connects to a tensile detector 300. The end of the connecting component 400 furthest from the tensile detector 300 is connected to a suction component 100. The tensile detector 300 is connected to the suction component 100 via the connecting component 400, thereby increasing the connection strength between the suction component 100 and the tensile detector 300 and improving testing reliability.

[0029] Furthermore, referring to Figure 3 The connecting assembly 400 includes a straight rod 410, a connecting nut 420, and a first connector 430, with the connecting nut 420 and the first connector 430 respectively fixedly connected to both ends of the straight rod 410. The suction assembly 100 is provided with a connecting screw 110, with the connecting nut 420 threadedly connected to the connecting screw 110. The tension detector 300 is provided with a second connector 310, with the first connector 430 and the second connector 310 rotatably connected. Specifically, the first connector 430 and the second connector 310 can rotate relative to each other in their circumference while maintaining their axial alignment. The connecting screw 110, connecting nut 420, straight rod 410, first connector 430, and second connector 310 are connected sequentially to achieve a fixed connection in a straight direction between the suction assembly 100 and the tension detector 300, further improving the reliability and accuracy of the tension detector 300 when performing tension detection. The connecting nut 420 and the connecting screw 110 are connected by threads, so that the suction assembly 100 and the connecting assembly 400 can be detachably connected. This makes it convenient to replace the suction assembly 100 of different sizes for testing, and it is suitable for testing the adhesion of more cartons of different specifications.

[0030] Furthermore, the second connector 310 is located at the top of the tensile detector 300. The second connector 310 is a screw structure, and the first connector 430 is a nut structure. The first connector 430 and the second connector 310 are threadedly connected. While enabling the first connector 430 and the second connector 310 to rotate relative to each other in their circumference and maintain their axial alignment, the threaded connection structure allows for a detachable connection between the first connector 430 and the second connector 310. This facilitates the replacement of tensile detectors 300 of different specifications and models for testing, and also allows for quick replacement in case of a malfunction in the tensile detector 300.

[0031] According to some embodiments of this application, refer to Figure 1 and Figure 3 The suction assembly 100 includes a suction cup 120 and a connecting block 130. The connecting block 130 has an internal airflow channel. The suction cup 120 is connected to one side of the connecting block 130, and the suction cup 120 and the airflow channel of the connecting block 130 are in communication. Specifically, the connecting block 130 is made of metal and has good mechanical strength. The airflow channel inside the connecting block 130 connects an external negative pressure source (generated by a vacuum generator 140 or a vacuum pump) to the suction cup 120, enabling negative pressure suction to be generated within the suction cup 120. Specifically, the suction cup 120 is connected to one side of the connecting block 130, and a connecting screw 110 is provided on the side of the connecting block 130 away from the suction cup 120. After the suction cup 120 adheres to the surface of the cardboard box, the tension between the suction cup 120 and the cardboard box can be transmitted to the connecting block 130, and then further transmitted to the detection mechanism via the connecting screw 110. The connecting block 130 can transmit the tension between the suction cup 120 and the carton to the detection mechanism, and can also connect the suction cup 120 to an external negative pressure source to achieve negative pressure suction of the suction cup 120.

[0032] Furthermore, the suction cup 120 is an accordion-style suction cup, which is connected to the detection mechanism on opposite sides of the connecting block 130. The accordion-style suction cup utilizes its pleated structure to conform to curved or inclined surfaces, making it suitable for adsorbing irregularly shaped or flexible cartons. Moreover, it has excellent cushioning performance, which can reduce the impact on the cartons when adsorbing and connecting them.

[0033] Furthermore, referring to Figure 1The suction assembly 100 also includes a silencer 150, a vacuum generator 140 connected to the silencer 150, a vacuum generator 140 connected to the airflow channel of the connecting block 130, and a vacuum generator 140 connected to the air source connecting assembly 200. Specifically, the vacuum generator 140 is connected to an external high-pressure air source through the air source connecting assembly 200, using the external high-pressure air source as a power source to drive the vacuum generator 140 to perform a negative pressure extraction operation. Specifically, the vacuum generator 140 is connected to the suction cup 120 through the connecting block 130 to extract negative pressure between the suction cup 120 and the connecting block 130, causing the suction cup 120 to generate negative pressure suction, thereby adsorbing the suction cup 120 onto the surface of the packaging carton. The silencer 150 is used to reduce the noise generated by the vacuum generator 140 during the negative pressure extraction process, thereby reducing the impact of noise on the production environment.

[0034] According to some embodiments of this application, refer to Figure 1 and Figure 3 The gas source connection component 200 includes a gas pipe 210, which is connected to the suction component 100. Specifically, one end of the gas pipe 210 is connected to the suction component 100, and the other end of the gas pipe 210 is connected to an external high-pressure gas source, so that the external high-pressure gas source transmits high-pressure gas to the vacuum generator 140 through the gas pipe 210 to provide power to the vacuum generator 140.

[0035] Furthermore, the air source connection assembly 200 also includes an air source connector 220, which is located at the end of the air pipe 210 away from the suction assembly 100 and is connected to the air pipe 210. The air source connector 220 facilitates connecting the suction assembly 100 to different high-pressure air source connection ports arranged within the production workshop, allowing the testing device to be easily moved to different locations within the production workshop for carton adhesion testing, thus improving convenience.

[0036] According to some embodiments of this application, refer to Figure 1 and Figure 3 The tension detector 300 includes a grip portion 320 and a pull ring portion 330. The grip portion 320 is disposed on opposite sides of the tension detector 300, and the pull ring portion 330 is disposed at the end of the tension detector 300 away from the suction assembly 100. The grip portion 320 and the pull ring portion 330 are used for a person to apply pulling force to the tension detector 300, so as to generate a pulling force between the suction cup 120 and the surface of the carton. Both the grip portion 320 and the pull ring portion 330 can provide a point of application for the person to apply pulling force, which is convenient for operators with different usage habits to perform detection operations, reduces slippage between the person's hand and the tension detector 300, and improves the reliability of detection.

[0037] It is understood that, in some other embodiments, reference is made to... Figures 1 to 3The vacuum connection assembly 400 also includes a pressure regulating valve 230, the two ends of which are connected to the air source connector 220 and the vacuum generator 140 respectively via air pipes 210. The pressure regulating valve 230 is used to adjust the high-pressure air source input pressure of the vacuum generator 140, so as to adjust the vacuum degree generated by the vacuum generator 140 on the suction cup 120, so that the carton adhesion force detection device can adapt to cartons of different thicknesses, meet the detection requirements of various cartons of different specifications, and has a wide range of applications.
