Description

Technical Field

[0001] This utility model relates to the field of plastic film production testing technology, and in particular to a plastic film production elongation testing device. Background Technology

[0002] Plastic film is made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins. It has been widely used in food, medicine, chemical and other fields. In order to ensure that plastic film can meet the strength requirements, its elongation needs to be tested during the production process.

[0003] In the production of plastic film, elongation is one of the important indicators for measuring the quality of plastic film. Appropriate elongation can ensure that plastic film has good flexibility and tensile strength during subsequent processing and use, avoiding problems such as cracking and deformation. However, existing plastic film production elongation testing devices have many shortcomings and cannot meet the growing demand for high-precision and high-efficiency testing in the plastic film production industry. Plastic films come in various specifications, including different thicknesses and materials. Traditional testing devices have fixed clamping sizes and clamping methods, which cannot meet the clamping requirements of films with different thicknesses. For films with large thickness differences, it is difficult to make flexible adjustments and accurately test the elongation of films of different specifications. Therefore, we propose a plastic film production elongation testing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a device for testing the elongation of plastic film production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A plastic film production stretchability testing device includes a square base. A testing component is mounted on the bottom surface of the square base, and an adjustment component is mounted on the back side of the square base. The adjustment component includes a square box mounted on the outer surface of the square base. A fixing plate is fixedly connected to the inner wall of the square box. An electric cylinder is fixedly mounted on the upper surface of the fixing plate. Two fixed sliding rods are fixedly connected to the outer surface of the fixing plate and the inner wall of the square box. A transmission slide plate is slidably connected to the outer surface of the two fixed sliding rods. The output end of the electric cylinder is fixedly connected to the outer surface of the transmission slide plate. Both ends of the transmission slide plate penetrate the square box and extend to the outside of the square box. Two connecting blocks are fixedly connected to the outer surface of the transmission slide plate. A clamping member is fixedly connected to the outer surface of each connecting block. Two fixed protrusions are fixedly connected to the upper surface of the square base.

[0007] In a further embodiment, the detection component includes a base frame mounted on the bottom surface of a square base. An electric push rod is fixedly connected to the inner wall of the base frame. A top component is fixedly connected to the output end of the electric push rod. A mounting groove is formed on the outer surface of the top component, and a force sensor is installed inside the mounting groove.

[0008] In a further embodiment, a controller is fixedly connected to the front of the base frame, and a display screen is mounted on the upper surface of the controller. Both the display screen and the mounting slot are electrically connected to the controller via wires.

[0009] In a further embodiment, a guide rail is fixedly connected to the front of the square box, a sliding block is slidably connected inside the guide rail, and the outer surface of the sliding block is fixedly connected to the outer surface of the top piece.

[0010] In a further embodiment, the bottom surface of the square base is fixedly connected to multiple support bases, and the upper surface of the square base is provided with an opening.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The two connecting blocks in the adjustment assembly of this device are connected to the clamping components, which can uniformly press the plastic film from both sides, ensuring that the film is subjected to uniform force in all parts during the testing process. The protective pads not only increase friction and prevent the film from slipping, but also prevent the clamping components from damaging the film surface, ensuring that the test results accurately reflect the true elongation performance of the film. Moreover, the electric cylinder can drive the clamping components up and down through the transmission slide plate, thereby adjusting the clamping force for films of different thicknesses. This allows the device to be quickly adjusted to a state suitable for testing different films, improving testing efficiency. The force sensor in the testing assembly is installed in the mounting groove of the top component, which can accurately measure the tensile force borne by the film during the stretching process, providing a strong guarantee for testing accuracy.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model discloses a plastic film production stretchability testing device, comprising a square base 1, a testing component 2 mounted on the bottom surface of the square base 1, a base frame 201 mounted on the bottom surface of the square base 1, an electric push rod 204 fixedly connected to the inner wall of the base frame 201, a top member 205 fixedly connected to the output end of the electric push rod 204, a mounting groove 206 formed on the outer surface of the top member 205, a force sensor 207 installed inside the mounting groove 206, a controller 202 fixedly connected to the front of the base frame 201, a display screen 203 mounted on the upper surface of the controller 202, and both the display screen 203 and the mounting groove 206 being electrically connected to the controller 202 via wires. The force sensor 207 of the testing component 2 is installed in the mounting groove 206 of the top member 205 to accurately measure the tensile force during film stretching. The controller 202 and the display screen 203 on the front of the base frame 201 are connected to the top member 205. The force sensor 207, connected to the control unit 203, transmits and displays data in real time, avoiding errors from manual measurement and facilitating monitoring and analysis of the testing process by operators. The electric push rod 204 pushes the top piece 205 upwards smoothly. The cylindrical top piece 205 applies pressure to the film. During testing, the controller 202 automatically records the data transmitted by the force sensor 207. After testing, production personnel can export the data from the controller 202 for analysis by connecting to external data analysis software, obtaining key performance indicators such as tensile strength and elongation at break of the film. Simultaneously, based on the real-time test results displayed on the screen 203, if the film's elongation does not meet standards, production personnel can immediately adjust production parameters such as the plastic raw material formula, production temperature, or stretching process to optimize the production process and avoid producing a large number of defective products.

[0024] An adjustment assembly 5 is installed on the back of the square base 1. The adjustment assembly 5 includes a square box 501 installed on the outer surface of the square base 1. A fixing plate 503 is fixedly connected to the inner wall of the square box 501. An electric cylinder 502 is fixedly installed on the upper surface of the fixing plate 503. Two fixed sliding rods 505 are fixedly connected to the outer surface of the fixing plate 503 and the inner wall of the square box 501. A transmission slide plate 504 is slidably connected to the outer surface of the two fixed sliding rods 505. The output end of the electric cylinder 502 is fixedly connected to the outer surface of the transmission slide plate 504. Both ends of the transmission slide plate 504 penetrate the square box 501 and extend to the outside of the square box 501. Two connecting blocks 506 are fixedly connected to the outer surface, and a clamping member 507 is fixedly connected to the outer surface of each connecting block 506. Two fixed protrusions 13 are fixedly connected to the upper surface of the square base 1. The fixed protrusions 13 are provided with arc protrusions, and the clamping member 507 is set to a size and shape that matches the fixed protrusions 13, so as to better clamp the plastic film and ensure clamping stability. The clamping member 507 connected to the two connecting blocks 506 of the adjusting component 5 clamps the plastic film evenly from both sides. The two fixed sliding rods 505 provide stable support and guidance for the transmission slide plate 504, so that the clamping member 507 moves smoothly, ensuring the smooth progress of the detection process and improving the reliability of the detection results.

[0025] A guide rail 3 is fixedly connected to the front of the square box 501. A sliding block 4 is slidably connected inside the guide rail 3. The outer surface of the sliding block 4 is fixedly connected to the outer surface of the top piece 205. When the top piece 205 moves, it can slide along the guide rail 3 with the sliding block 4 to prevent the top piece 205 from tilting and to ensure that the film always maintains a straight line during the stretching process, thus avoiding film offset or twisting. Multiple support seats 11 are fixedly connected to the bottom surface of the square base 1. An opening 12 is opened on the upper surface of the square base 1. The support seats 11 provide stable support for the entire device, and the opening 12 can ensure the smooth up and down movement of the top piece 205 and avoid collisions.

[0026] Each clamping component 507 has a fixed plate 8 fixedly connected to its outer surface, and a plug rod 9 fixedly connected to the bottom surface of each fixed plate 8. Two circular cylinders 10 are fixedly connected to the front of the square base 1. When the clamping component 507 clamps the film, the plug rod 9 can be inserted into the circular cylinder 10 to ensure the stability of the clamping component 507. A protective pad 7 is connected to the bottom surface of each clamping component 507. The outer surface of the square box 501 is provided with a square sliding opening 6 that matches the transmission slide plate 504. The protective pad 7 not only increases friction and prevents the film from sliding, but also avoids damage to the film surface caused by the clamping component 507, ensuring that the test results accurately reflect the true elongation performance of the film. The transmission slide plate 504 can slide along the square sliding opening 6, making its movement more stable.

[0027] The working principle of this utility model is as follows:

[0028] The plastic film to be tested is placed on the upper surface of the square base 1, so that the film is located on the two fixed protrusions 13. Then, the electric cylinder 502 in the adjustment component 5 can be started to run, so that its running output end can push the transmission slide plate 504 to slide down on the two fixed slide rods 505. When the transmission slide plate 504 moves, it moves the pressing member 507 down through the connecting block 506, so that the protective pad 7 on the bottom surface of the pressing member 507 tightly presses the film onto the square base 1, thereby achieving a stable reinforcement of the film.

[0029] Then, the electric push rod 204 in the detection component 2 can be activated to push the top member 205 upward. The upward movement of the top member 205 generates a pushing force on the plastic film, and the film is stretched and deformed by the upward force. At the same time, the force sensor 207 can detect the magnitude of the tensile force on the film in real time and transmit the data to the display screen 203 through the controller 202 for display, so as to observe the detection results.
