Description

Technical Field

[0001] This application relates to the field of packaging bag production technology, and in particular to a material tester. Background Technology

[0002] Packaging bags are indispensable practical tools in daily life and industrial production. They provide sealed protection for various items such as food, clothing, and electronic components, isolating them from external dust, moisture, and pollution. They also facilitate storage and transportation, and can convey product information and enhance brand recognition through printed patterns and text. From snack bags in supermarkets to express delivery bags in logistics, from household food storage bags to heavy-duty packaging bags used in industry, their shapes and materials vary depending on their uses, but their core functions always revolve around "protection, storage, and information transmission."

[0003] In the production of packaging bags, testing materials with a material testing machine is a crucial step in ensuring product quality and safety. The mechanical properties, puncture resistance, and temperature resistance of packaging bag materials directly determine their load-bearing capacity, protective effect, and service life. If the material performance does not meet the standards, it may lead to problems such as damage during transportation and seal failure. The material testing machine can test the puncture resistance of packaging bag materials, thereby accurately detecting whether the materials meet production standards, promptly identifying material defects, and providing a basis for selecting suitable raw materials and optimizing production processes. This ensures that the final product meets packaging requirements and reduces quality risks and economic losses caused by material problems.

[0004] When testing packaging bag materials, the packaging bag materials can be placed on a material clamp first, and then the material clamp can be used to fix the material. After that, the material is tested by a pressure contact head. However, when placing and fixing the packaging bag materials, because the packaging bag materials are soft, they are prone to shifting when placed on the material clamp, which causes wrinkles after the material is fixed, thus affecting the accuracy of subsequent material testing. Utility Model Content

[0005] The purpose of this application is to solve the problem in the above-mentioned background technology that when placing and fixing packaging bag materials, the soft texture of the packaging bag materials makes them prone to displacement when placed on the material clamp, resulting in wrinkles after the materials are fixed, which in turn affects the accuracy of subsequent material testing. This application provides a material tester.

[0006] To achieve the above objectives, this application specifically adopts the following technical solution:

[0007] A material tester includes a base, a motion track fixedly connected to one top side of the base, and a display fixedly connected to the other top side of the base. A connecting plate is fixedly connected to the motion track, and a pressure sensor is fixedly connected to the bottom of the connecting plate. A detachable pressure contact is installed at the bottom end of the pressure sensor. A connecting seat is fixedly connected to one top side of the base, and a material clamp is installed on the top of the connecting seat. The material clamp is located directly below the pressure contact. A negative pressure mechanism is fixedly connected to one top side of the base, and the suction end of the negative pressure mechanism is connected to the material clamp. The pressure sensor is electrically connected to the display.

[0008] By adopting the above technical solution, when testing materials, the internal components of the negative pressure mechanism can operate under the operation of the negative pressure mechanism, thereby evacuating the material clamp and creating negative pressure at the material release point of the material clamp. This will adsorb the material placed on the material clamp, improve the stability of the material placement, ensure that the material will not shift when the staff spreads and flattens it, and fix the material flat on the material clamp, reducing the possibility of wrinkles and improving the accuracy of the test.

[0009] Furthermore, the pressure contact includes a connector that is inserted into the bottom of the pressure sensor, and a pressure contact head is fixedly connected to the bottom of the connector. The connector and the pressure sensor are fixedly connected by a plug.

[0010] By adopting the above technical solution, the connection between the connector and the pressure sensor can be disconnected by manually pulling out the plug, and the pressure contact head can be replaced by manually pulling out the connector from the pressure sensor.

[0011] Furthermore, the material clamp includes a lower clamping plate installed at the top of the connecting seat, with connecting ear plates one fixedly connected to both sides of the lower clamping plate, a threaded rod fixedly connected to the top of the connecting ear plate one, a connecting ear plate two passing through the threaded rod, an upper clamping plate fixedly connected to one side of the connecting ear plate two, and a threaded sleeve threadedly connected to the threaded rod.

[0012] By adopting the above technical solution, the material can be clamped by the cooperation of the lower clamping plate and the upper clamping plate.

[0013] Furthermore, the upper clamping plate has an inner cavity, and an elastic pressure member is provided inside the inner cavity.

[0014] By adopting the above technical solution, the material can be elastically clamped by the contact between the elastic element and the material.

[0015] Furthermore, the elastic pressure member includes a plurality of elastic elements fixedly connected inside the inner cavity, and an abutment plate is fixedly connected to the bottom end of the elastic element, and an anti-slip layer is provided at the bottom end of the abutment plate.

[0016] By adopting the above technical solution, the anti-slip layer is made of rubber, which can increase the friction between the contact plate and the material, thereby improving the stability of fixing the material.

[0017] Furthermore, the elastic element includes a sleeve rod fixedly connected to the top of the inner cavity, a spring fixedly connected inside the sleeve rod, an inner rod fixedly connected to the end of the spring away from the sleeve rod, and the inner rod fixedly connected to the contact plate.

[0018] By adopting the above technical solution, the clamping force can be buffered by the spring.

[0019] Furthermore, the negative pressure mechanism includes an exhaust fan fixedly connected to the top of the base, a connecting pipe fixedly connected to the exhaust end of the exhaust fan, a corrugated hose fixedly connected to one end of the connecting pipe, an adsorption element provided inside the lower clamping plate, and one end of the corrugated hose communicating with the adsorption element.

[0020] By adopting the above technical solution, the air inside the connecting pipe and corrugated hose can be extracted by the operation of the exhaust fan, and the material can be adsorbed by the adsorption component.

[0021] Furthermore, the adsorption component includes a connecting air box fixedly connected to the bottom of the lower clamping plate, and a plurality of suction heads are fixedly connected to the top of the connecting air box. The suction heads are connected through the lower clamping plate, and the connecting air box is connected to a corrugated hose.

[0022] By adopting the above technical solution, materials can be adsorbed through multiple suction heads.

[0023] In summary, this application includes at least one of the following beneficial effects;

[0024] 1. In this application, when testing materials, the internal components of the negative pressure mechanism can be operated under the operation of the negative pressure mechanism to evacuate the material clamp, thereby creating a negative pressure at the material release point of the material clamp, which in turn adsorbs the material placed on the material clamp, improves the stability of the material placement, ensures that the material will not shift when the staff lays and stretches it, and fixes the material flat on the material clamp, reducing the possibility of wrinkles in the material and improving the accuracy of the test.

[0025] 2. In this application, when fixing the material, the material can be placed on the material clamp. By manually operating the material clamp, the components of the material clamp fix the material. During this process, the internal elastic components buffer the compressive force applied to the material by the material clamp to prevent the clamping force from being too large and deforming the material. This avoids the material deformation from affecting the accuracy of the test, thereby improving the accuracy of subsequent material testing. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1 —5 provides further detailed description of this application.

[0034] This application discloses a material tester.

[0035] Reference Figure 1 and Figure 2A material tester includes a base 1, a motion track 2 fixedly connected to one side of the top of the base 1, and a display 3 fixedly connected to the other side of the top of the base 1. A connecting plate 4 is fixedly connected to the motion track 2, and a pressure sensor 5 is fixedly connected to the bottom of the connecting plate 4. A detachable pressure contact 6 is installed at the bottom of the pressure sensor 5. A connecting seat 7 is fixedly connected to one side of the top of the base 1, and a material clamp 8 is installed on the top of the connecting seat 7. The material clamp 8 is located directly below the pressure contact 6. A negative pressure mechanism 9 is fixedly connected to one side of the top of the base 1. The suction end of the negative pressure mechanism 9 is connected to the material clamp 8. The pressure sensor 5 is electrically connected to the display 3. The pressure contact 6 includes a connector 62 inserted into the bottom of the pressure sensor 5. A pressure contact head 61 is fixedly connected to the bottom of the connector 62. The connector 62 and the pressure sensor 5 are fixedly connected by a plug 63.

[0036] When testing packaging bag materials, the materials are first placed on the material clamp 8. Then, the negative pressure mechanism 9 operates, causing its internal components to draw air from the material clamp 8, creating a negative pressure at the material dispensing point. This suctions the material onto the clamp 8, improving its stability. After suction, the material can be manually pulled to flatten it and eliminate surface wrinkles. Manual operation of the material clamp 8 causes its internal components to rotate, clamping the packaging bag material. During this process, the elastic components inside the clamp 8 buffer the clamping force on the material, achieving elastic clamping. Afterwards, the material is... The operation of the motion track 2 causes the connecting plate 4 and pressure sensor 5 to move towards the material clamp 8, and causes the pressure contact 6 to contact and squeeze the material on the material clamp 8. During this process, the pressure sensor 5 detects the applied pressure. When the pressure contact 6 breaks through the material on the material clamp 8, it is the material puncture limit value, which will be displayed on the display 3 for easy viewing. This allows for material testing. When the pressure contact head 61 needs to be replaced, the connection between the connector head 62 and the pressure sensor 5 can be disconnected by manually pulling out the insertion rod 63, and then the connector head 62 can be manually pulled out from the pressure sensor 5 to replace the pressure contact head 61.

[0037] Reference Figure 3 and Figure 4The material clamp 8 includes a lower clamping plate 81 installed at the top of the connecting seat 7. Both sides of the lower clamping plate 81 are fixedly connected to connecting ear plates 82. A threaded rod 83 is fixedly connected to the top of the connecting ear plates 82. A connecting ear plate 85 is connected through the threaded rod 83. An upper clamping plate 84 is fixedly connected to one side of the connecting ear plate 85. A threaded sleeve 86 is threadedly connected to the threaded rod 83. An inner cavity is opened inside the upper clamping plate 84. An elastic pressure member is provided inside the inner cavity. The elastic pressure member includes multiple elastic members 88 fixedly connected inside the inner cavity. A contact plate 87 is fixedly connected to the bottom end of the elastic member 88. An anti-slip layer is provided at the bottom end of the contact plate 87. The elastic member 88 includes a sleeve rod 881 fixedly connected to the top of the inner cavity. A spring 882 is fixedly connected inside the sleeve rod 881. An inner rod 883 is fixedly connected to the end of the spring 882 away from the sleeve rod 881. The inner rod 883 is fixedly connected to the contact plate 87.

[0038] The material is placed on the lower clamping plate 81, and the connecting ear plate 85 is inserted into the threaded rod 83, so that the upper clamping plate 84 corresponds to the lower clamping plate 81, and the contact plate 87 is brought into contact with the material surface. Then, by manually operating the screw sleeve 86, the screw sleeve 86 is threadedly connected to the threaded rod 83, which restricts the connecting ear plate 85. As the screw sleeve 86 continuously squeezes the connecting ear plate 85, the contact plate 87 continuously squeezes the material on the lower clamping plate 81. During this period, the extrusion force applied by the contact plate 87 can be buffered by the elastic action of the spring 882, so that the material clamping fixture 8 can elastically clamp the material and prevent the material from being deformed due to excessive clamping force. Here, the anti-slip layer is made of rubber material, which can improve the friction between the contact plate 87 and the material, thereby improving the stability of the material fixation.

[0039] Reference Figure 5 The negative pressure mechanism 9 includes an exhaust fan 91 fixedly connected to the top of the base 1. The exhaust end of the exhaust fan 91 is fixedly connected to a connecting pipe 92. One end of the connecting pipe 92 is fixedly connected to a corrugated hose 93. An adsorption element is provided inside the lower clamping plate 81. One end of the corrugated hose 93 is connected to the adsorption element. The adsorption element includes a connecting air box 94 fixedly connected to the bottom of the lower clamping plate 81. Multiple exhaust heads 95 are fixedly connected to the top of the connecting air box 94. The exhaust heads 95 are connected through the lower clamping plate 81. The connecting air box 94 is connected to the corrugated hose 93.

[0040] When the material is placed on the lower clamping plate 81, the exhaust fan 91 evacuates air from the inside of the connecting pipe 92, and then from the inside of the corrugated hose 93 and the air box 94, creating a negative pressure inside the connecting pipe 92, corrugated hose 93 and air box 94. Then, multiple exhaust heads 95 evacuate air from the lower clamping plate 81, creating a negative pressure there as well. This negative pressure then adheres to the material placed on the lower clamping plate 81, preventing it from moving. This allows the staff to better flatten the material, reducing the possibility of material shifting and wrinkling, and improving testing accuracy. Here, the height of the exhaust head 95 is the same as the top surface of the lower clamping plate 81.

[0041] Working principle: When testing packaging bag materials, the materials are first placed on the material clamp 8. Then, by running the exhaust fan 91, air is drawn from the connecting pipe 92, and subsequently from the corrugated hose 93 and the connecting air box 94, creating a negative pressure within these components. Multiple suction heads 95 then draw air from the lower clamp 81, creating a negative pressure there as well. This negative pressure then adsorbs the material placed on the lower clamp 81, improving its stability. After adsorption, the material can be manually pulled to flatten it and eliminate surface wrinkles. The material clamp 8 is then manually operated to ensure the material... The internal components of the clamp 8 operate to clamp the packaging bag material. During this process, the internal elastic components of the clamp 8 can buffer the clamping force on the packaging bag material, thus achieving elastic clamping of the material. Then, the operation of the motion track 2 causes the connecting plate 4 and pressure sensor 5 to move towards the material clamp 8, and causes the pressure contact member 6 to contact and squeeze the material on the material clamp 8. During this process, the pressure sensor 5 detects the applied pressure. When the pressure contact member 6 breaks through the material on the material clamp 8, it is the material puncture limit value, and the value will be displayed on the display 3 for easy viewing, thus realizing the testing of the material.
