Description

Technical Field

[0001] The invention relates to the technical field of PE film detection equipment, in particular to a strength detection device for PE film generation and processing. Background Art

[0002] PE film, the full name of which is polyethylene film, is a thermoplastic polymer obtained by polymerization of ethylene. It is one of the most widely used polymer materials in the world today. After the production of PE film is completed, the film body needs to be tested for strength. PE film strength testing equipment is a special instrument used to measure the mechanical properties of PE film. It can quickly test PE film, thereby improving the qualified rate of PE film production.

[0003] For example, the publication number is CN215727301U, which discloses a strength detection device for PE film generation and processing, including a base plate, a bracket and a tester. The bracket is L-shaped, and the bracket is fixedly mounted on the left wall of the base plate. A buffer frame is fixedly mounted on the right bottom wall of the bracket. The upper and lower ends of the tester are respectively fixedly mounted with a buffer rod and a pull rod. The top of the buffer rod is set on the buffer frame, and the bottom of the buffer rod is provided with two limit mechanisms. This kind of strength detection device for PE film generation and processing, the utility model is provided with a buffer frame, a buffer plate, a rubber pad and a buffer spring. When the tested PE film is tempered, the buffer plate pushes the rubber pad by pressing, and the rubber pad then produces a violent impact on the buffer spring, thereby realizing the elastic buffering and protection of the buffer rod and the tester. The utility model realizes the protection of the tester when the PE film is broken during the test, thereby improving the service life of the tester.

The inner end surfaces of the two sets of second synchronous pulleys 27 are fixedly provided with a transmission screw 25, and a stepper motor 23 is arranged at the upper end surface of the support guide seat 24 opposite to the transmission screw 25, the lower end surface of the support guide seat 24 is threadedly connected to the threaded guide seat 21 through the transmission screw 25, and five sets of detection devices 22 are equidistantly arranged on the inner end surface of the threaded guide seat 21.

[0037] The detection device 22 includes a clamping slide 226, two groups of spring pins 225 are arranged on the side end surface of the clamping slide 226, and a detection head 224 is fixedly clamped at the center of the lower end surface of the clamping slide 226, a limiting slide shaft 221 is fixedly arranged at the center of the upper end surface of the clamping slide 226, and a spring clamp ring 223 is arranged in the middle of the upper end surface of the clamping slide 226, and a first pressure sensor 222 is arranged on the top of the spring clamp ring 223.

[0038] The feeding device 3 includes a ball slide 33, the front end face of the ball slide 33 is equidistantly provided with five groups of reduction motors 34, and a bidirectional screw 35 is fixedly provided at the output end of the reduction motor 34, the inner end face of the ball slide 33 is equidistantly threadedly connected with five groups of threaded guide seats 32 through the bidirectional screw 35, and the inner end face of the threaded guide seat 32 is elastically slidably clamped with an anti-tear detection device 31.

[0039] The anti-tear detection device 31 includes a guide slide 316, a clamping cylinder 312 is arranged on the upper end face of the guide slide 316, and two sets of limit clamps 311 for clamping are arranged on the front end face of the clamping cylinder 312, a spring guide shaft 313 is fixedly arranged at the center of the rear end face of the clamping cylinder 312, and a limit stop seat 314 is arranged at the tail end of the spring guide shaft 313, and a second pressure sensor 315 is fixedly arranged on the inner end face of the limit stop seat 314.

[0040] The lower end surface of the threaded guide seat 21 is fixedly connected to the first pressure sensor 222, and the clamping slide 226 is slidably clamped in the interior of the threaded guide seat 21 through the limiting slide shaft 221. The first pressure sensor 222 is fixed at the bottom of the threaded guide seat 21, which can facilitate the detection head 224 to detect the strength of the PE film. The first pressure sensor 222 can sense the elastic force of the compression of the spring clamp 223, and then accurately sense the strength of the PE film.

[0041] The side end surface of the snap-in slide 226 is fixedly snapped into the inside of the detection head 224 through the spring pin 225. The detection head 224 can be elastically fixedly snapped into the inside of the snap-in slide 226 through the spring pin 225, so that subsequent staff can replace different detection heads 224 according to needs to detect different types of PE films.

[0042] The second pressure sensor 315 is fixedly connected to the inside of the threaded guide seat 32, and the ball slide seat 33 is threadedly connected to the inside of the fixed clamp 4 through the guide screw 1. The second pressure sensor 315 is fixed inside the threaded guide seat 32. When the threaded guide seat 32 is pulled outward, it can drive the spring guide shaft 313 to elastically contract. The second pressure sensor 315 can accurately sense the pulling force of the limit clamp 311, which is convenient for the subsequent detection of the tear resistance of the PE film.

[0043] Working principle: When testing multiple groups of PE films, the staff can position the multiple groups of PE films to be tested between the two groups of limit clamps 311, and then start the clamping cylinder 312. The clamping cylinder 312 can fix and limit the PE films to be tested through the limit clamps 311. Then, the tearing strength of the PE films is tested first, and the reduction motor 34 is started. The five groups of reduction motors 34 can drive the bidirectional screw rod 35 to rotate. At the same time, the bidirectional screw rod 35 can be connected with the two groups of threaded guide seats 32 through threads, thereby synchronously driving the two groups of threaded guide seats 32. The thread guide seat 32 is centrifugally displaced, and the limit clamp 311 can be relatively displaced with the thread guide seat 32 driven by the PE film. At this time, the guide slide 316 inside the thread guide seat 32 can drive the spring guide shaft 313 to lengthen, thereby driving the limit stopper 314 to press the second pressure sensor 315 at the rear of the thread guide seat 32. When the preset value of the second pressure sensor 315 is reached, the reduction motor 34 is closed, and the ruptured PE film is unqualified. After the tear resistance performance test is completed, the staff can start the servo motor 7. The servo motor 7 can drive the guide screw 1 to rotate through the first synchronous pulley 5 and the first synchronous belt 6. The guide screw 1 can be connected with the ball slide 33 through a thread, thereby driving the PE film that has been tested to be positioned directly below the guide device 2. The other set of ball slides 33 can synchronously perform the above-mentioned steps of testing the tear resistance of the PE film. When the PE film is positioned at the bottom of the guide device 2, the stepper motor 23 is started, and the stepper motor 23 can drive the two sets of transmission screws 25 to move forward through the second synchronous pulley 27 and the second synchronous belt 26. The two sets of transmission screw rods 25 can be connected with the threaded guide seat 21 through threads, thereby synchronously driving the threaded guide seat 21 and the five sets of detection devices 22 to move downward, and the detection head 224 can press the PE film when moving downward. At the same time, the first pressure sensor 222 can judge the pressing strength through the spring clamp 223. When the preset strength is reached, the stepper motor 23 stops running, and the PE film that is not broken meets the composite detection requirements. The staff can also pull the two sets of spring pins 225 to quickly and conveniently replace different types of detection heads 224.
