Technical Field

[0001] The utility model relates to the field of detection devices, in particular to a polypropylene film detection device. Background Technique

[0002] The polypropylene drawn film is a pre - process in the production process of flexible intermediate bulk containers (FIBCs). First, polypropylene granules are melted using a hot - melt extruder, and then a forming die at the outlet end of the extruder is used to form a polypropylene film. Under the traction of a lifting and traction device, it is cooled and shaped through a cooling water tank, and finally cut by a cutting device to form polypropylene flat filaments for weaving cylindrical FIBCs on a circular loom. Especially during the cooling and shaping process of the polypropylene film, the tension of the lifting and traction device needs to be adjusted according to the process requirements.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 ,Figure 4 , wherein, Figure 1 is a schematic structural view of a preferred embodiment of a polypropylene film detection device provided by the present utility model; Figure 2 is Figure 1 the front view of a polypropylene film detection device shown; Figure 3 is Figure 1 the front view of a support table in a polypropylene film detection device shown; Figure 4 is Figure 1 the front view of a positioning seat in a polypropylene film detection device shown. A polypropylene film detection device includes a support table 1. A limit groove 2 is provided at the top of the support table 1. A limit block 3 is movably sleeved inside the limit groove 2. A positioning seat 4 is fixedly connected to the top of the limit block 3. A stretching seat 5 is movably sleeved inside the limit groove 2. A tension meter 6 is fixedly installed at the top of the stretching seat 5. A fixed clamp 7 is fixedly connected to the side of the tension meter 6. A control host 8 is fixedly installed at the top of the support table 1. A threaded column 9 is movably sleeved at the top of the positioning seat 4. A lifting plate 10 is externally threaded and sleeved on the threaded column 9. An anti-slip plate 11 is fixedly connected to the bottom of the lifting plate 10. A rotary motor 12 is fixedly installed on the side of the support table 1. A bidirectional threaded rod 13 is fixedly connected to the output shaft of the rotary motor 12. A sliding ball 14 is movably sleeved at the bottom of the positioning seat 4. A protection mechanism 15 is provided at the top of the support table 1. A moving mechanism 16 is provided at the bottom of the support table 1.

[0026] The input end of the tension meter 6 is in signal connection with the output end of the control host 8, and the number of the tension meters 6 is four; by setting the tension meter 6, when performing tension detection on multiple polypropylene films, one end of the film is fixed at the top of the positioning seat 4. At this time, the other end of the film is clamped and fixed inside the fixed clamp 7. At this time, the tension meter 6 is started and the stretching seat 5 is moved, so that the stretching seat 5 drives multiple tension meters 6 to move, that is, stretches multiple polypropylene films, thereby achieving the effect of simultaneous tension detection of multiple polypropylene films, and further avoiding the problem that single independent detection is required when detecting the tension of different types of polypropylene films, resulting in a low speed of film tension detection, thereby improving the efficiency of polypropylene film tension detection.

[0027] The limit block 3 is located directly below the positioning seat 4, and the limit block 3 is adapted to the limit groove 2; by setting the limit block 3, when the positioning seat 4 and the stretching seat 5 are moved, the limit block 3 can limit the horizontally moving positioning seat 4 and stretching seat 5 through the limit groove 2, so that the positioning seat 4 and the stretching seat 5 can stably horizontally stretch the polypropylene film, thereby improving the smoothness of the polypropylene film during stretching.

[0028] The threaded post 9 is perpendicular to the lifting plate 10, and the number of threaded posts 9 is two; by setting the threaded post 9, when fixing the film, a plurality of films are placed on the top of the positioning seat 4. At this time, the threaded post 9 is rotated, so that the threaded post 9 drives the lifting plate 10 to move up and down, and then presses on the top of the plurality of films, thereby achieving the clamping and fixing effect of the film, and further achieving the effect of fixing a plurality of films at the same time, which brings convenience to the clamping and fixing of a plurality of films.

[0029] The anti-slip plate 11 is perpendicular to the support table 1, and the material of the anti-slip plate 11 is rubber material; by setting the anti-slip plate 11, when clamping and fixing the film, the anti-slip plate 11 greatly increases the friction between the film and the lifting plate 10, avoiding the problem that the film falls off when stretched due to the relatively smooth surface of the film.

[0030] The bidirectional threaded rod 13 is threadedly sleeved inside the limit block 3, and the bidirectional threaded rod 13 is perpendicular to the positioning seat 4; by setting the bidirectional threaded rod 13, when performing the film stretching test, the rotation motor 12 is started, so that the rotation motor 12 drives the two limit blocks 3 to move horizontally through the bidirectional threaded rod 13, that is, drives the positioning seat 4 and the stretching seat 5 to move horizontally, so that the positioning seat 4 and the stretching seat 5 can slowly and continuously stretch the film, thereby achieving the film stretching test effect.

[0031] The number of sliding balls 14 is several, and several sliding balls 14 are evenly distributed at the bottom of the positioning seat 4; by setting the sliding balls 14, when the positioning seat 4 moves horizontally, the sliding balls 14 support the horizontally moving positioning seat 4, avoiding the problem of friction between the positioning seat 4 and the support table 1 when moving, thereby improving the smoothness of the positioning seat 4 when moving.

[0032] The protection mechanism 15 includes a sliding groove 151 opened on the top of the support table 1, and a protective cover 152 is movably sleeved inside the sliding groove 151; by setting the protection mechanism 15, when performing the film stretching test, the protective cover 152 is slid, so that the protective cover 152 can move horizontally to the outside of the positioning seat 4, thereby achieving the covering effect of the film, avoiding the problem that the film is ejected when stretched and broken, resulting in accidental injury to the staff, and thus improving the safety during the film tension test.

[0033] The moving mechanism 16 includes a support column 161 which is fixedly connected to the bottom of the support platform 1. A sliding wheel 162 is installed at the bottom of the support column 161. By providing the moving mechanism 16, when moving and transporting the detection device, the support platform 1 is pushed, so that the sliding wheel 162 drives the support platform 1 to move horizontally through the support column 161, that is, drives the positioning seat 4 to move horizontally, thus achieving the effect of moving and transporting the film detection device, and further bringing convenience to the adjustment of the working position of the detection device.

[0034] The working principle of a polypropylene film detection device provided by the present utility model is as follows:

[0035] First step: When detecting the tensions of multiple polypropylene films, one end of the film is fixed to the top of the positioning seat 4. At this time, the other end of the film is clamped and fixed inside the fixed clamp 7. Then the tension meter 6 is started and the stretching seat 5 is moved, so that the stretching seat 5 drives a plurality of tension meters 6 to move, that is, stretches a plurality of polypropylene films, thus achieving the effect of simultaneously detecting the tensions of a plurality of polypropylene films. Furthermore, it avoids the problem that the detection speed of the film tension is low due to the need for single independent detection when detecting the tensions of different types of polypropylene films, thereby improving the efficiency of detecting the tension of polypropylene films. When the positioning seat 4 and the stretching seat 5 are moving, the limiting block 3 limits the horizontally moving positioning seat 4 and stretching seat 5 through the limiting groove 2, so that the positioning seat 4 and the stretching seat 5 can stably stretch the polypropylene film horizontally, thereby improving the smoothness of the polypropylene film during stretching. When fixing the film, a plurality of films are placed on the top of the positioning seat 4. At this time, the threaded column 9 is rotated, so that the threaded column 9 drives the lifting plate 10 to move up and down, and then presses on the top of a plurality of films, thus achieving the effect of clamping and fixing the film, and further achieving the effect of simultaneously fixing a plurality of films, which brings convenience to the clamping and fixing of a plurality of films. When clamping and fixing the film, the anti-slip plate 11 greatly improves the friction between the film and the lifting plate 10, so as to avoid the problem that the film peels off during stretching due to the relatively smooth surface of the film.

[0036] Step 2: When performing the film tensile test, start the rotary motor 12, so that the rotary motor 12 drives the two limit blocks 3 to move horizontally through the bidirectional threaded rod 13, that is, drives the positioning seat 4 and the stretching seat 5 to move horizontally, so that the positioning seat 4 and the stretching seat 5 can slowly and continuously stretch the film, thus achieving the film tensile test effect. When the positioning seat 4 moves horizontally, the sliding ball 14 supports the horizontally moving positioning seat 4, avoiding the problem of friction between the positioning seat 4 and the support table 1 during movement, thereby improving the smoothness of the positioning seat 4 during movement. When performing the film tensile test, slide the protective cover 152, so that the protective cover 152 can move horizontally to the outside of the positioning seat 4, thus achieving the covering effect on the film, avoiding the problem of the film being ejected when it breaks during stretching, resulting in accidental injury to the staff, and thus improving the safety during the film tension test. When moving and transporting the testing device, push the support table 1, so that the sliding wheel 162 drives the support table 1 to move horizontally through the support column 161, that is, drives the positioning seat 4 to move horizontally, thus achieving the effect of moving and transporting the film testing device, and bringing convenience to the adjustment of the working position of the testing device.

[0037] Compared with the related art, a polypropylene film testing device provided by the present utility model has the following beneficial effects:

[0038] By setting the tension gauge 6, when performing the tension test on multiple polypropylene films, one end of the film is fixed on the top of the positioning seat 4, and at this time, the other end of the film is clamped and fixed inside the fixed clamp 7. Then start the tension gauge 6 and move the stretching seat 5, so that the stretching seat 5 drives the multiple tension gauges 6 to move, that is, stretch the multiple polypropylene films, thus achieving the effect of simultaneously testing the tension of multiple polypropylene films, and avoiding the problem that the tension test of different types of polypropylene films requires single independent tests, resulting in a low film tension test speed, and thus improving the efficiency of the polypropylene film tension test.
