[0002] During the production and use process, it is necessary to carry out necessary tensile testing on polyethylene resin film, which can help discover and solve defects and problems in the film and ensure that the quality and performance of the film meet the standard requirements. The polyethylene resin film stretching machine is a device used to test the tensile properties of plastic film.

[0030] Reference Figure 1-5 The utility model provides a polyethylene resin film stretching machine, comprising:

[0031] The main unit 100 includes a bottom plate 101, a controller 102 is mounted on the surface of the bottom plate 101, a plurality of support rods 103 are fixedly connected to the upper side of the bottom plate 101, and a fixing ring 104 is fixedly connected to the upper end of the support rod 103;

[0032] The stretching unit 200 includes a rotating ring 201 rotatably connected to the fixed ring 104, and a plurality of fixed plates 202 are fixedly connected to the surface of the rotating ring 201, the upper surface of each group of fixed plates 202 is rotatably connected to a threaded rod 203, and the surface of the threaded rod 203 is rotatably connected to a pressing plate 204 through a thread, the middle part of each group of pressing plates 204 is slidably connected to a limiting rod 205, and the lower end of the limiting rod 205 is fixedly connected to the fixed plate 202, an electric lifting rod 208 is arranged in the middle part of the rotating ring 201, and the lower end of the electric lifting rod 208 is fixedly connected to the bottom plate 101, the electric lifting rod 208 is electrically connected to the controller 102, and an unfolding component 209 is arranged at the output end of the electric lifting rod 208.

[0033] Among them, the unfolding component 209 includes a fixed seat 209a fixedly connected to the output end of the electric lifting rod 208, and a flip groove is opened on the upper side of the fixed seat 209a. Two groups of vertical rods 209b are rotatably connected inside the flip groove through a rotating shaft, and screw holes are opened inside the vertical rods 209b. Bolts 209c are threadedly connected in the two groups of screw holes. By threading the bolts 209c, the two groups of vertical rods 209b can be flipped outward, thereby being able to perform a tensile test on the strip polyethylene resin film.

[0034] Furthermore, the upper ends of the two groups of vertical rods 209b are fixedly connected with soft blocks 209d, and the soft blocks 209d are all made of rubber, which has a protective effect, so that the vertical rods 209b will not pierce the special-shaped polyethylene resin film when lifting it.

[0035] Furthermore, the adjacent sides of the two sets of vertical rods 209b are both arc-shaped, and the upper surface of the fixing seat 209a is arc-shaped. When the two sets of vertical rods 209b are flipped outward and lift up the polyethylene resin film, the arc design can effectively protect the polyethylene resin film.

[0036] Furthermore, the adjacent end surfaces of each set of pressure plates 204 are fixedly connected with a soft sleeve 207, and the adjacent ends of the soft sleeves 207 are all curved in design, and the upper side surfaces of each set of fixed plates 202 are fixedly connected with a soft pad 206 that matches the soft sleeve 207, and each set of soft pads 206 and soft sleeves 207 are made of rubber, which increases friction and makes the pressure plates 204 and the fixed plates 202 clamp the polyethylene resin film more firmly.

[0037] Furthermore, the upper side of the fixed ring 104 is fixedly connected to the limiting ring 105, and the interior of the rotating ring 201 is provided with a rotating groove that matches the limiting ring 105, which has a limiting effect, so that the rotating ring 201 will not separate from the surface of the fixed ring 104 when rotating.

[0038] During use, one corner of the polyethylene resin film is placed on the surface of the soft pad 206, and the threaded rod 203 is manually rotated. The pressure plate 204 threadedly connected to the threaded rod 203 descends under the limiting action of the limiting rod 205, so that the soft sleeve 207 and the soft pad 206 clamp the polyethylene resin film, and then the rotating ring 201 is manually turned to rotate, and the other corners of the polyethylene resin film are clamped in sequence, and then the electric lifting rod 208 is started to rise slowly, so that the vertical rod 209b and the soft block 209d lift the middle part of the polyethylene resin film, thereby achieving multi-angle stretching of the polyethylene resin film, making the detection data more real and comprehensive, and manually rotating the bolt 209c to disengage the threaded connection between the bolt 209c and a group of screw holes, so that the two groups of vertical rods 209b can be flipped outward. Through this arrangement, the flipped vertical rod 209b can lift and measure the strip polyethylene resin film.
