Description

Technical Field

[0001] This utility model belongs to the technical field of multilayer co-extruded film testing devices, specifically a multilayer co-extruded film quality testing device. Background Technology

[0002] Food-grade multilayer co-extruded film is a composite film made by co-extrusion blow molding or casting processes to form multiple polymer materials in one step. It is specially designed for food packaging and combines safety, functionality and environmental protection. To ensure its reliability in actual packaging, transportation and use, food-grade multilayer co-extruded film needs to be tested for tensile strength.

[0003] In the prior art, during the tensile strength test of multilayer co-extruded film, the two ends of the co-extruded film are simply clamped by two symmetrical clamps and then stretched for testing. However, the simple clamping of the two ends of the co-extruded film can easily cause the co-extruded film to fall off during the stretching process, thus affecting the tensile test results. Summary of the Invention

[0004] The purpose of this invention is to provide a multilayer co-extruded film quality inspection device that can clamp the two ends of the co-extruded film more firmly and prevent the co-extruded film from falling off during the tensile testing process.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A multilayer co-extruded film quality testing device is provided, comprising a test platform. Two mounting plates are installed on the upper surface of the test platform. One mounting plate is fixedly connected to the left side of the upper surface of the test platform, and the other mounting plate is slidably connected to the upper surface of the test platform. A recessed frame is fixedly connected to the outer walls of the two mounting plates. An electric telescopic rod is fixedly connected to the outer walls of the two mounting plates. A clamping seat is fixedly connected to the telescopic end of the electric telescopic rod. The clamping seat is slidably connected inside the recessed frame. A groove is formed inside the clamping seat. A co-extruded film body is provided on the outer wall of the clamping seat. One end of the co-extruded film body is placed in the groove of the clamping seat. A clamping block is slidably connected inside the clamping seat. A bolt is threaded inside the clamping block. The bolt is threaded inside the clamping seat. The outer wall of the co-extruded film body fits against the inner wall of the recessed frame. A driving assembly is installed inside the two mounting plates. The driving assembly is used to stretch the co-extruded film body.

[0006] Optionally, the drive assembly includes a motor and a lead screw. The motor is fixedly connected to the outer wall of the left mounting plate, and the lead screw is rotatably connected to the inside of the left mounting plate. The left end of the lead screw is fixedly connected to the output end of the motor. Another mounting plate is threadedly connected to the outer wall of the lead screw, and a tension sensor is fixedly connected to the outer wall of the other mounting plate.

[0007] Optionally, a baffle is fixedly connected to the right side of the upper surface of the test platform, the lead screw is rotatably connected inside the baffle, a guide rod is fixedly connected between the mounting plate on the left side and the baffle, and another mounting plate is slidably connected to the outer wall of the guide rod.

[0008] Optionally, a support frame is fixedly connected to the upper surface of the test bench, a cylinder is fixedly connected to the upper surface of the support frame, and a pressure plate is fixedly connected to the output end of the cylinder.

[0009] Optionally, a pressure rod is fixedly connected to the lower surface of the pressure plate, a pressure sensor is fixedly connected to the upper surface of the pressure plate, and the lower surface of the pressure rod is in contact with the upper surface of the co-extruded film body.

[0010] Optionally, a controller is installed on one side of the outer wall of the test bench, and the tension sensor and pressure sensor are connected to the controller via wires.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model uses an electric telescopic rod to push the clamping seat, causing the clamping seat to move outward and disengage from the inside of the concave frame. After rotating the bolt to remove it, the clamping block is disengaged from the inside of the clamping seat. One end of the co-extruded film body is placed inside the clamping seat and wrapped around the outer wall of the clamping seat. After inserting the clamping block into the inside of the clamping seat, the clamping seat and the clamping block are connected by bolt threads to clamp and fix one end of the co-extruded film body inside the clamping seat. Then, the electric telescopic rod is activated to drive the clamping seat to slide into the concave frame, so that the clamping seat and the concave frame clamp and fix the co-extruded film body wrapped around the outer wall of the clamping seat. This improves the stability of clamping both ends of the co-extruded film body and prevents both ends of the co-extruded film body from falling off during the stretching process, thus affecting the stretching effect.

[0012] 2. This utility model uses a starting motor to drive a lead screw to rotate. The rotation of the lead screw causes another mounting plate to move to the right, which in turn moves one end of the co-extruded film body to the right, performing a tensile test on the co-extruded film body. A tension sensor records the tensile force data generated during the tensile process, testing the lateral tensile strength of the co-extruded film body. Simultaneously, a cylinder can be activated to move the pressure plate and pressure rod downward, causing the pressure rod to apply pressure to the co-extruded film body. Combined with a pressure sensor recording the pressure data, the longitudinal tensile strength of the co-extruded film body is tested, thus realizing the tensile strength detection of the co-extruded film body.

[0022] Please refer to another embodiment of this utility model as well. Figures 1 to 4The drive assembly includes a motor 9 and a lead screw 10. The motor 9 is fixedly connected to the outer wall of the left mounting plate 2, and the lead screw 10 is rotatably connected to the inside of the left mounting plate 2. The left end of the lead screw 10 is fixedly connected to the output end of the motor 9. Another mounting plate 2 is threadedly connected to the outer wall of the lead screw 10. A tension sensor 13 is fixedly connected to the outer wall of the other mounting plate 2. The tension sensor 13 records the tension data of one end of the co-extruded film body 6 by the mounting plate 2 threadedly connected to the outer wall of the lead screw 10. A baffle 11 is fixedly connected to the right side of the upper surface of the test bench 1. The baffle 11 serves as a limit. The lead screw 10 is rotatably connected to the inside of the baffle 11. A guide rod 12 is fixedly connected between the left mounting plate 2 and the baffle 11. The other mounting plate 2 slides... A dynamic connection is made to the outer wall of the guide rod 12, which serves to limit and guide movement. A support frame 14 is fixedly connected to the upper surface of the test bench 1, and a cylinder 15 is fixedly connected to the upper surface of the support frame 14. A pressure plate 16 is fixedly connected to the output end of the cylinder 15, and a pressure rod 17 is fixedly connected to the lower surface of the pressure plate 16. A pressure sensor 18 is fixedly connected to the upper surface of the pressure plate 16. The lower surface of the pressure rod 17 contacts the upper surface of the co-extruded film body 6. Pressure is applied to the upper surface of the co-extruded film body 6 by the downward movement of the pressure plate 16 and the pressure rod 17, thus testing the longitudinal tensile strength of the co-extruded film body 6. A controller 19 is installed on one side of the outer wall of the test bench 1. The tensile sensor 13 and the pressure sensor 18 are connected to the controller 19 via wires. The controller 19 centrally receives and processes sensor data and automates the entire testing process. It connects the tension sensor 13 and the pressure sensor 18 via wires to collect and process tensile and pressure test data in real time. At the same time, it can coordinate and control the operation of actuators such as the motor 9, cylinder 15 and electric telescopic rod 4 to realize the automated operation of clamping, lateral tensile and longitudinal pressure testing, thereby effectively improving the accuracy and efficiency of the testing process. It uses existing technologies known in the field to control the relevant components.

[0023] Working principle: In use, firstly, the electric telescopic rods 4 on the outer walls of the two mounting plates 2 are activated to drive the clamping seat 5 to slide, causing the clamping seat 5 to slide out of the interior of the recessed frame 3. The two ends of the co-extruded film body 6 are then wrapped around the outer wall of the clamping seat 5. The clamping block 7 is removed by rotating the bolt 8. Then, the two ends of the co-extruded film body 6 are extended into the groove of the clamping seat 5. The clamping block 7 is then inserted into the interior of the clamping seat 5. The clamping seat 5 and the clamping block 7 are threaded together and fixed using the bolt 8, so that the clamping block 7 clamps and fixes the two ends of the co-extruded film body 6. Then, the electric telescopic rods 4 are activated to drive the clamping seat 5 to slide into the interior of the recessed frame 3, so that the clamping seat 5 and the recessed frame 3 clamp and fix the two ends of the co-extruded film body 6, preventing the two ends of the co-extruded film body 6 from falling off during the tensile test, improving the clamping stability of the co-extruded film body 6, and simultaneously increasing the tensile strength. To test the efficiency and accuracy of the tensile strength test, the motor 9 is started, driving the lead screw 10 to rotate. This causes the mounting plate 2 on the right side to move the right end of the co-extruded film body 6 to the right. During the movement, a tensile force is generated on the co-extruded film body 6, and the tensile force data is recorded by the tensile sensor 13. This allows for a transverse tensile strength test of the co-extruded film body 6. At the same time, the cylinder 15 can be started to move the pressure plate 16 and the pressure rod 17 downward. After the pressure rod 17 moves downward, it applies pressure to the upper surface of the co-extruded film body 6, causing the co-extruded film body 6 to indent downward. This allows for a test of the longitudinal tensile strength of the co-extruded film body 6. Combined with the pressure sensor 18 recording the pressure data generated by the pressure plate 16 and the pressure rod 17 on the co-extruded film body 6, it is possible to perform tensile strength tests in two directions on the co-extruded film body 6, ensuring the reliability of the co-extruded film body 6 during actual packaging, transportation, and use.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
