Abstract
Description
Technical Field
[0001] This utility model relates to the field of stretch film testing technology, and in particular to a stretch film processing elasticity testing device. Background Technology
[0002] Stretch film, also known as heat shrink film, was initially produced in China using PVC as the base material and DOA as a plasticizer for self-adhesion. However, due to environmental concerns, high cost (relatively higher density than PE, resulting in smaller packaging area per unit area), and poor tensile strength, it was gradually phased out when PE stretch film production began in China in 1994-1995. PE stretch film initially used EVA as the self-adhesive material, but its high cost and odor led to the development of PIB and VLDPE as self-adhesive materials. The base material is primarily LLDPE, including C4, C6, C8, and metallocene PE (MPE).
[0003] Existing stretch film testing devices do not have the capability to perform puncture tests under tension. They can only perform simple static tension tests while fixing the stretch film. They also cannot simulate the dynamic conditions experienced by the stretch film in actual use, such as the rapid stretching and rebound process. Utility Model Content
[0004] This invention provides a device for testing the elasticity of stretch film processing, which solves the above-mentioned structural technical problems of not being able to perform puncture tests under tension and being unable to simulate the dynamic conditions experienced by stretch film in actual use, and the process of rapid stretching and rebound.

An L-shaped bracket is provided, with a first electric telescopic rod on one side of the L-shaped bracket. A fixing block is fixed to one side of the first electric telescopic rod, and one side of the fixing block is connected to one side of the slide groove. Multiple puncture needles are arranged in a linear equidistant array on the other side of the L-shaped bracket. A U-shaped bracket is fixed to the outer wall of the column away from the slide groove. A sliding column is provided between the two sides of the inner side of the U-shaped bracket. A sliding block is slidably connected to the outer wall of the sliding column. One side of the sliding block is connected to one end of the L-shaped bracket. A lower clamping assembly is provided on the top of the operating table base near one side.
[0006] The beneficial effects of this utility model are as follows: the operating table base mainly serves to provide support; the column facilitates the provision of a testable stretching height; the speed-regulating motor drives the lead screw to rotate; the lead screw nut can move axially along the lead screw; the auxiliary components allow the lead screw nut to move linearly; the bearing seat can fix the top of the lead screw; the upper and lower clamping components can clamp and fix the top and bottom of the wrapping film; the sliding groove and slider allow the first electric telescopic rod to move linearly with the L-shaped bracket; the fixing block can support one side of the first electric telescopic rod; the puncture needle facilitates puncture experiments on the wrapping film; the U-shaped bracket supports the sliding column; the sliding column facilitates the linear movement of the sliding block, thus assisting the L-shaped bracket in moving to complete the puncture experiment.

A U-shaped bracket 15 is fixed to the outer wall of the column 2 away from the slide groove 9. A sliding column 16 is provided between the two sides of the inner side of the U-shaped bracket 15. A sliding block 17 is slidably connected to the outer wall of the sliding column 16. One side of the sliding block 17 is connected to one end of the L-shaped bracket 11. A lower clamping assembly 18 is provided on the top of the operating table base 1 near one side. Example
[0024] like Figure 1-7 As shown, the upper clamping assembly of 7 pieces includes a support block 71, which is located on one side of the lead screw nut 6. A frame 72 is provided on one side of the support block 71. A first extrusion layer 73 is provided on one side of the inner side of the frame 72. A connecting frame 74 is fixed on the top of the frame 72. Two second electric telescopic rods 75 are provided on one side of the connecting frame 74. An extrusion plate 76 is provided between the two second electric telescopic rods 75 on one side. A second extrusion layer 77 is provided on one side of the extrusion plate 76.

[0025] In this embodiment, the support block 71 can easily support the frame 72, the frame 72 can easily allow the top of the stretch film to pass through, the first extrusion layer 73 can easily increase the friction on the upper side of the stretch film, the connecting frame 74 can support the second electric telescopic rod 75, the second electric telescopic rod 75 can move linearly with the extrusion plate 76, the extrusion plate 76 can extrude one side of the stretch film with the second extrusion layer 77, and the first circular opening 78 can easily allow the second electric telescopic rod to pass through and move. Example
[0026] like Figure 1-7As shown, the auxiliary component 8 includes a movable plate 81, which is located on the other side of the lead screw nut 6. A sliding opening 82 is provided on one side of the movable plate 81. A fixed plate 83 is provided on one side of the column 2 near the top. A movable column 84 is provided at the bottom of the fixed plate 83. The lower clamping component 18 includes two limiting plates 181, which are located on the top of the operating table base 1. One limiting plate 181 has a third extrusion layer 182 on one side, and the other limiting plate 181 has an L-shaped plate 183 on one side. Two third electric telescopic rods 184 are provided on one side of the L-shaped plate 183. A push plate 185 is provided between the two third electric telescopic rods 184 on one side. A fourth extrusion layer 186 is provided on one side of the push plate 185. Two second circular openings 187 are provided on the other side of the other limiting plate 181.
[0027] In this embodiment, the movable plate 81 can easily support the connecting screw nut 6, and the sliding port 82 can pass through the movable column 84, which makes it easy to change the movement of the connected screw nut 6, so that it can change from axial movement to linear movement. The fixed plate 83 can support the top of the movable column 84, and the limiting plate 181 can easily limit the placement area of the wrapping film. The third electric telescopic rod 184 can push the pushing plate 185 and the fourth extrusion layer 186 to extrude one side of the wrapping film to the third extrusion layer 182, which can facilitate the extrusion and fixation of the bottom two sides of the wrapping film. The second round opening 187 can facilitate the passage and movement of the third electric telescopic rod 184.
[0028] Working principle: When a stretch film test is required, the bottom side of the stretch film is first pressed by the third electric telescopic rod 184, which carries the push plate 185 and the fourth extrusion layer 186, so that the bottom side of the stretch film can be attached to the side of the third extrusion layer 182. After clamping, the top side of the stretch film is attached to the side of the first extrusion layer 73 by the second electric telescopic rod 75, which carries the extrusion plate 76 and the second extrusion layer 77. When a stretch film stretch test is required, the speed-regulating motor 5 rotates the lead screw 4, and the lead screw nut 6 moves along the axial direction of the lead screw 4. The lead screw nut 6 is connected to the moving plate 81, and the sliding port 82 on the moving plate 81 can move linearly along the moving column 84, thereby allowing the lead screw nut 6 to move. The upper clamping assembly of 7 pieces can move linearly. After the stretch film moves upward and is stretched, when a puncture test is required, the No. 1 electric telescopic rod 12 moves the L-shaped bracket 11 on the slide groove 9 and the slider 10 linearly, allowing the L-shaped bracket 11 to carry multiple puncture needles 14 through the stretch film. The sliding column 16 and the sliding block 17 can assist in connecting one end of the L-shaped bracket 11, making the movement of the L-shaped bracket 11 stable. This allows multiple puncture needles 14 to move and puncture the stretch film more effectively, simulating the dynamic situation experienced in actual use and completing the process of rapid stretching and rebound. It also facilitates puncture tests on the stretch film under stretching.
