Description

Technical Field

[0001] The invention relates to the technical field of cover tape production, in particular to a strength detection device for heat-sealed cover tape production. Background Art

[0002] Heat-seal cover tape is a material widely used in the packaging industry. It uses a heat-sealing process to provide sealing protection for products such as food, pharmaceuticals, and chemicals, and boasts excellent heat resistance, sealing properties, and mechanical strength. During the production process, the strength of the heat-seal cover tape directly impacts its performance during subsequent processing and actual use. Insufficient strength can lead to seal failure, compromising packaging quality and even posing a safety hazard. Therefore, during the production of heat-seal cover tape, its strength must be tested to ensure that the material's quality and performance meet standard requirements. Strength testing devices simulate actual operating conditions to test the material's strength, providing a basis for production control and playing a crucial role in ensuring the quality of heat-seal cover tape.

[0003] Currently, the strength of heat-sealing cover tape is primarily tested using mechanical testing devices and static tensile testing devices. Mechanical testing devices apply tensile force to determine the tensile strength and breaking point of the heat-sealing cover tape, providing an intuitive and accurate test. Static tensile testing devices, on the other hand, assess the strength and ductility of the sample by gradually increasing the load. However, these existing devices typically only have a single testing function and cannot adapt to the needs of multiple testing methods. For example, in different application scenarios, a heat-sealing cover tape may require comprehensive testing of its compression resistance, tear resistance, and multi-dimensional stress characteristics. However, traditional devices struggle to meet these testing requirements simultaneously, limiting the comprehensiveness and flexibility of the test. Summary of the Invention

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the present specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Please see the attached Figure 1 -Attached Figure 2The embodiment of the present invention provides a strength detection device for heat-sealed cover tape production, comprising a workbench 1, a detection cone 1 37 and a detection cone 2 38. A stretching mechanism is provided on the top of the workbench 1, a side plate 10 is fixedly connected to the side wall of the workbench 1, a pressing mechanism is provided at the bottom of the side plate 10, the stretching mechanism and the pressing mechanism are connected through a linkage mechanism, a display 39 is provided on the top of the workbench 1 for convenient real-time display of data; a quick-release mechanism is provided at the bottom of the pressing mechanism, and the detection cone 1 37 and the detection cone 2 38 are both connected to the pressing mechanism through the quick-release mechanism, which is convenient for quick replacement of the detection cone 1 37 and the detection cone 2 38; a blower mechanism is provided on the top of the pressing mechanism for cleaning the detection area and improving the detection accuracy; a pressure sensor 40 is provided at the bottom of the detection cone 2 38, and the pressure sensor 40 is electrically connected to the display 39, which can It can accurately transmit pressure data for real-time monitoring; the stretching mechanism includes a fixed frame 2, which is fixedly connected to the top of the workbench 1, and a bidirectional screw 3 is rotatably connected between the fixed frame 2. The top of the workbench 1 is fixedly connected to a limit frame 4, and the side wall of the bidirectional screw 3 is threadedly connected to a slide 5, and the slide 5 is slidably connected to the side wall of the limit frame 4. The structural design is compact and the operation is stable. A motor 6 is fixedly connected to the top of the workbench 1, and the output end of the motor 6 is connected to one end of the bidirectional screw 3, and bidirectional movement is achieved by driving the motor 6; a tension detector 7 is arranged between the slides 5, and the slide 5 and the tension detector 7 are connected by a connecting line 8 to ensure stable transmission of tension data. A clamping claw 9 is arranged on the top of the slide 5 to stably clamp objects. The tension detector 7 is electrically connected to the display 39 to achieve real-time visualization of detection data.

[0031] When using this equipment to test the strength of heat-sealed cover tape during production, first firmly fix the two ends of the sample of the heat-sealed cover tape by means of the clamps 9 to ensure that the sample remains stable and without displacement, so as not to affect the test results. Subsequently, by starting the motor 6, the motor 6 drives the bidirectional screw 3 to rotate precisely. Under the constraint and guidance of the limit frame 4, the two slides 5 begin to move evenly from the middle of the workbench 1 to both sides, thereby stably stretching the sample. During the movement of the slide 5, the tension detector 7 monitors the tension exerted on the sample in real time through the connecting line 8. The sensor is sensitive, ensuring the accurate capture of the tension data, and the specific value is immediately sent to the display 39 through signal transmission. The display 39 will update in real time and intuitively display the change curve and specific value of the tension exerted on the sample, which is convenient for the staff to observe and analyze.

[0032] Please see the attached Figure 2 -Attached Figure 5The pressing mechanism includes a mounting plate 11, which is mounted on the bottom of the side plate 10 to ensure the overall stability of the device; the bottom of the side plate 10 is fixedly connected to an articulated frame 12, which is internally rotatably connected to a connecting plate 15, which is internally rotatably connected to a connecting rod 16, and the bottom of the connecting rod 16 is fixedly connected to a movable frame 14, so that the entire pressing action can be completed efficiently and smoothly. The linkage mechanism includes an articulated frame 2 13, the side wall of the articulated frame 2 13 is firmly fixed to the bottom of the mounting plate 11, the articulated frame 2 13 is internally rotatably connected to a connecting plate 2 17, which is internally rotatably connected to a connecting rod 2 18, which is rotatably connected to the side wall of the movable frame 14, ensuring the synchronization and accuracy of the linkage process, and the top of one side slide 5 is fixedly connected to an articulated frame 3 19, which is internally rotatably connected to a push rod 21, one end of the push rod 21 is rotatably connected to a connecting rod 20, and one end of the connecting rod 20 is firmly fixed to the connecting plate The second side wall 17, the hair dryer includes a diverter ring 22, which is set at the top of the mobile frame 14 and can effectively achieve uniform distribution of airflow and improve the blowing effect. The mobile frame 14 is fixedly connected to a plurality of air outlet pipes 23 inside. Each air outlet pipe 23 runs through the side wall of the mobile frame 14 and extends to the bottom to ensure a wider blowing coverage. The top of the mobile frame 14 is provided with a fan 24, which can provide a stable airflow output. The side wall is fixedly connected to a wind cover 25, which not only plays a protective role, but also optimizes the guiding performance of the airflow. The wind cover 25 is fixedly connected to the inside of the connecting pipe 26, wherein one end of the connecting pipe 26 is fixedly connected to the inside of the diverter ring 22, further enhancing the efficiency and stability of the airflow transmission.

[0033] When the slide 5 is moving, its movement will drive the articulated frame 3 19 to move accordingly. The movement of the articulated frame 3 19 further drives one end of the push rod 21 to rotate flexibly inside the articulated frame 3 19, while the other end thereof rotates on the side wall of the connecting rod 20 and pulls the connecting rod 20 to move in the specified direction. This action simultaneously drives the connecting plate 2 17 to rotate smoothly inside the articulated frame 2 13, so that one end of the connecting rod 2 18 rotates inside the connecting plate 2 17, and the other end exerts force during the rotation of the movable frame 14 to press the movable frame 14 downward. At the same time as the movable frame 14 is pressed downward, the connecting plate 1 15 and the connecting rod 1 16 undergo fine deflection adjustment during the pressing process, which effectively absorbs the offset force and ensures the smooth and uniform downward action of the overall pressing action. When the movable frame 14 moves downward, the fan 24 is started, and the strong airflow generated by the fan 24 flows into the interior of the diverter ring 22 through the connecting pipe 26, and the clean airflow is directly blown to the top surface of the sample by the evenly distributed outlets of multiple air outlet pipes 23. This design effectively disperses any dust or fine particles that may be adhering to the top of the sample, ensuring surface cleanliness during testing and preventing external interference from affecting test results. Simultaneously, the downward pressure of the mobile frame 14 secures the second test cone 38 against the sample surface, and a high-precision pressure sensor 40 mounted at the bottom of the second test cone 38 begins to measure the pressure applied to the sample surface in real time. This pressure data is quickly and accurately transmitted via signal transmission to the display 39, which simultaneously displays the value, allowing personnel to accurately and accurately determine the maximum pressure the sample top can withstand under tension.

[0034] Please see the attached Figure 5 -Attached Figure 9 The quick release mechanism includes a fixing ring 27, which is fixedly connected to the bottom of the mobile frame 14. The bottom of the fixing ring 27 is fixedly connected to an extension column 28. A recessed hole 29 is opened inside the extension column 28. A limit ball 30 is set inside the recessed hole 29. The side wall of the connecting rod 18 is provided with a spring 31. The spring 31 provides the necessary elastic recovery effect when subjected to force. The side wall of the fixing ring 27 is slidably connected to a collar 32. One side of the collar 32 is in contact with the extension column 28. One end of the spring 31 is fixedly connected to the side of the fixing ring 27. The other end of the spring 31 is fixedly connected to the inside of the ring 32. The side wall of the ring 32 is provided with anti-slip grooves 33 to improve the friction during operation and facilitate the gripping operation. The extension column 28 is slidably connected to a block 34. The side wall of the block 34 is provided with a snap ring 35. The side wall of the block 34 is fixedly connected to a limit block 36. The limit block 36 is slidably connected to the inside of the extension column 28. The limit balls 30 are all slidably connected to the inside of the snap ring 35. The detection cone 2 38 and the detection cone 1 37 are both connected to the movable frame 14 through a quick release mechanism.

[0035] To test the puncture resistance of the tensioned heat-sealed cover tape, the collar 32 is manually slid upward. This process applies a squeezing force to the spring 31, compressing it and temporarily releasing its restraining force on the stop ball 30. This releases the restraining force within the retaining ring 27. The second detection cone 38 can then be removed from the device and inserted downward. The upper connecting block 34 of the first detection cone 37 is then aligned with the interior of the retaining ring 27 and inserted. During insertion, the snap ring 35 of the block 34 is aligned with the structure of the retaining ring 27 and the stop ball 30 to ensure the secure fixation of the first detection cone 37. After insertion, the collar 32 is released. The spring 31 quickly returns to its original position after the external force is removed, pushing the collar 32 back to its original position. At the same time, the stop ball 30 effectively re-constrains the block 34, ensuring the installation stability and operational reliability of the first detection cone 37. After installation, the operator can start the device and repeat the aforementioned operation process to test the puncture resistance of the tensioned heat-sealed cover tape.

[0036] Working principle: When using this equipment to test the strength of heat-sealed cover tape during production, first fix the two ends of the heat-sealed cover tape sample with the clamping claws 9, then start the motor 6 to drive the bidirectional screw 3 to rotate, and under the restriction of the limit frame 4, the two slides 5 move from the middle of the workbench 1 to the sides, thereby stretching the sample. During the movement of the slide 5, the tension detector 7 and the connecting line 8 can detect the tension exerted on the sample at this time, and transmit the specific value to the display 39 for the staff to observe. When the slide 5 is in the middle of the workbench 1, the tension detector 7 and the connecting line 8 can detect the tension exerted on the sample at this time, and transmit the specific value to the display 39 for the staff to observe. During the movement, the articulated frame 3 19 will be driven to move, so that one end of the push rod 21 will rotate inside the articulated frame 3 19, and the other end will rotate on the side wall of the connecting rod 20, and pull the connecting rod 20 to move, thereby synchronously driving the connecting plate 2 17 to rotate inside the articulated frame 2 13, so that one end of the connecting rod 2 18 will rotate inside the connecting plate 2 17, and the other end will press the moving frame 14 downward while the moving frame 14 rotates. When the moving frame 14 moves downward, the connecting plate 15 and the connecting rod 1 16 will be deflected, thereby ensuring the stability of the downward pressure, and the moving frame 1 4 starts the fan 24 while moving downward, and the generated air enters the inside of the diverter ring 22 through the connecting pipe 26, and is then blown to the top of the sample through the air outlet pipe 23, blowing off the dust or fine particles that may be attached to the top of the sample. When the movable frame 14 moves downward so that the detection cone 2 38 presses on the surface of the sample, the pressure sensor 40 at the bottom of the detection cone 2 38 will detect the applied pressure and also transmit the value to the display 39, so that the value of the pressure that the top of the heat-sealing cover belt can withstand when it is tensioned can be known. When the heat-sealing cover belt needs to be tensioned, whether it is puncture-resistant When testing, before using the equipment, the ring 32 can be slid upward to squeeze the spring 31 and make the limiting ball 30 lose its restriction. At this time, the detection cone 2 38 is taken out downward, and the block 34 connected to the detection cone 1 37 is inserted into the interior of the fixed ring 27. After the insertion is completed, the ring 32 is loosened. At this time, the spring 31 loses pressure and resets, pushing the ring 32 to move, so that it restricts the limiting ball 30 again, ensuring the stability of the installation of the detection cone 1 37. Then repeat the above operation to test the puncture resistance of the heat-sealed cover belt after tensioning.
