Description

Technical Field

[0001] This invention relates to the field of puncture testing technology, and more particularly to a puncture testing device for the production of PE protective film. Background Technology

[0002] PE protective film is a high-molecular-weight organic compound based on polyethylene plastic film. As the simplest and most widely used polymer material in the world today, it is divided into high-density, medium-density, and low-density polyethylene protective films according to density differences. Its main function is to prevent product surfaces from being contaminated, corroded, or scratched during production, processing, transportation, and storage, thereby maintaining smoothness and enhancing market competitiveness. Before production, PE film also needs to undergo a puncture test, mainly to test the film's toughness.

[0003] Currently, when using puncture devices to perform puncture tests on PE films in existing technologies, it is not convenient to simultaneously perform puncture tests on the middle and edges of the film, which affects the puncture test effect of the PE film and thus affects the production quality of the PE film. Therefore, this invention proposes a puncture test device for the production of PE protective films. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies where PE films are not convenient for simultaneous puncture testing of the middle and edges, which affects the puncture test results and consequently the production quality of PE films.

[0005] To achieve the above objectives, the present invention employs the following technical solution: a puncture testing device for PE protective film production, comprising a support mechanism, a positioning mechanism mounted on the support mechanism, and a puncture mechanism mounted on the support mechanism, wherein the positioning mechanism is driven and connected to the puncture mechanism; the support mechanism includes four supporting legs and a fixed bracket, wherein the supporting legs are fixedly connected to the four corners of the lower surface of the fixed bracket; the positioning mechanism includes four rotating seats, wherein the four rotating seats are respectively fixedly connected to the four corners of the outer wall edge of the fixed bracket, wherein a fixed block is rotatably installed in each rotating seat, and an upper connecting rod is fixedly connected to the outer side of each fixed block.

[0006] In at least some embodiments, a side pressure block is fixedly connected to one end of the upper connecting rod, the side pressure block is located on both sides of the fixed bracket, and a side support rod is fixedly connected to the lower end of each upper connecting rod, the side support rod being inclined.

[0008] In at least some embodiments, the sliding bracket is slidably mounted in the four support legs via a limiting protrusion, and a protruding handle is fixedly connected to the front surface of the sliding bracket.

[0009] In at least some embodiments, the puncture mechanism includes two fixed seats, which are respectively fixed to the upper surface of the side pressure block, and rotating components are rotatably mounted on both sides of the upper end of the fixed seats.

[0010] In at least some embodiments, a slip ring is rotatably mounted on the outer side of each of the rotating components, and a transversely arranged transverse rod is slidably mounted between two parallel slip rings, with an upper connecting block fixedly connected to the middle of the lower surface of the two transverse rods.

[0011] In at least some embodiments, a mounting bracket is fixedly connected to the lower surface of the upper connecting block, and a plurality of evenly distributed lateral puncture needles are fixedly connected to the edge of the lower surface of the mounting bracket, and a sliding groove is provided in the middle of the mounting bracket.

[0012] In at least some embodiments, two sliders are slidably installed in the groove, a first connecting block is fixedly connected to the upper end of the two sliders, a second connecting block is fixedly connected to the upper surface of the first connecting block, and a central puncture needle is fixedly connected to the lower surface of the two sliders.

The transverse rod can drive the mounting bracket to descend, and then the side puncture needle on the lower surface of the mounting bracket can perform a puncture test on the edge of the PE film.

Detailed Implementation

[0018] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0020] In existing technologies, PE protective film is a high-molecular organic compound with polyethylene plastic film as its base material. As the simplest and most widely used polymer material in the world today, it is divided into high-density, medium-density, and low-density polyethylene protective films according to density differences. Its main function is to prevent the surface of products from being contaminated, corroded, or scratched during production, processing, transportation, and storage, thereby maintaining its smoothness and enhancing market competitiveness. However, before production, PE film needs to undergo a puncture test, mainly to test the film's toughness. When using a puncture needle to perform a puncture test on PE film, it is not convenient to simultaneously puncture the center and edges of the film, which affects the puncture test results and thus the production quality of the PE film.

[0021] Therefore, the objective of this invention is at least to fix the protective film on the upper surface of the fixed bracket 102 by driving the side pressure block 209 at the upper end of the upper connecting block 206 through the positioning mechanism 200, and to drive the fixed seat 305 on the upper surface of the two side pressure blocks 209 to rotate and install the slip ring 304 through the rotating member 306. The transverse rod 303 can be slidably installed in the two slip rings 304. The transverse rod 303 can drive the mounting bracket 301 to descend, and then the side puncture needle 307 on the lower surface of the mounting bracket 301 can perform a puncture test on the edge of the PE film.

[0022] Implementation examples, based on Figures 1-7 This invention provides a puncture testing device for PE protective film production, comprising a support mechanism 100, a positioning mechanism 200 mounted on the support mechanism 100, and a puncture mechanism 300 mounted on the support mechanism 100. The positioning mechanism 200 is drivenly connected to the puncture mechanism 300. Figure 3 As shown, the support mechanism 100 includes four support legs 101 and a fixed bracket 102. The support legs 101 are fixedly connected to the four corners of the lower surface of the fixed bracket 102. The positioning mechanism 200 includes four rotating seats 208. The four rotating seats 208 are respectively fixedly connected to the four corners of the outer wall edge of the fixed bracket 102. A fixing block 207 is rotatably installed in each rotating seat 208. An upper connecting rod 206 is fixedly connected to the outside of each fixing block 207.

[0023] like Figure 4As shown, one end of the upper connecting rod 206 is fixedly connected to a side pressure block 209, which is located on both sides of the fixed bracket 102. Each upper connecting rod 206 has a side support rod 205 fixedly connected to its lower end. The side support rod 205 is inclined, and an inclined limiting block 204 is slidably installed on the inner side of the side support rod 205. A sliding bracket 201 is fixedly connected to the inner side of the inclined limiting block 204. Limiting protrusions 202 are fixedly connected to the outer edges of the sliding bracket 201. 01 is slidably installed in the four support legs 101 by limiting protrusions 202. A protruding handle 203 is fixedly connected to the front surface of the sliding bracket 201. Pulling the protruding handle 203 causes the sliding bracket 201 to rise and fall in the four support legs 101. Through the inclined limiting blocks 204 on both sides, the upper connecting block 206 and the side support rod 205 can be pushed to rotate around the rotating seat 208, thereby driving the side pressure block 209 at the upper end of the upper connecting block 206, so that the protective film is fixed on the upper surface of the fixed bracket 102.

[0024] like Figures 6-7 As shown, the puncture mechanism 300 includes two fixed seats 305, which are respectively fixed to the upper surface of the side pressure block 209. Rotating components 306 are rotatably mounted on both sides of the upper end of each fixed seat 305. A slip ring 304 is rotatably mounted on the outer side of each rotating component 306. A transversely arranged transverse rod 303 is slidably mounted between the two parallel slip rings 304. An upper connecting block 302 is fixedly connected to the middle of the lower surface of the two transverse rods 303. A mounting bracket 301 is fixedly connected to the lower surface of the upper connecting block 302. Several evenly distributed side puncture needles 307 are fixedly connected to the edge of the lower surface of the mounting bracket 301. A groove 308 is formed in the middle of the mounting bracket 301. Two sliders 310 are slidably mounted in the groove 308. A connecting rod is fixedly connected to the upper end of the two sliders 310. Block 309, a second connecting block 309 is fixedly connected to the upper surface of the first connecting block 309, a central puncture needle 311 is fixedly connected to the lower surface of the two sliders 310, a drive screw 315 is meshed between the two second connecting blocks 309, a dual-axis motor 314 is fixedly connected to the inner side of the drive screw 315, a motor bracket 313 is fixedly connected to both sides of the dual-axis motor 314, and the motor bracket 313 is fixedly connected to the inner surface of the upper connecting block 302. Since the fixed seat 305 on the upper surface of the two side pressure blocks 209 is rotatably mounted with a slip ring 304 through a rotating part 306, a transverse rod 303 can be slidably mounted inside the two slip rings 304. The transverse rod 303 can drive the mounting bracket 301 to descend, and then the side puncture needle 307 on the lower surface of the mounting bracket 301 can perform a puncture test on the edge of the PE film.

[0025] The working principle of this invention is as follows: Pulling the protruding handle 203 causes the sliding bracket 201 to rise and fall within the four support legs 101. After passing through the inclined limiting blocks 204 on both sides, the upper connecting block 206 and the side support rod 205 can be pushed to rotate around the rotating seat 208, thereby driving the side pressure block 209 at the upper end of the upper connecting block 206, so that the protective film is fixed on the upper surface of the fixed bracket 102. Since the fixed seat 305 on the upper surface of the two side pressure blocks 209 is rotatably mounted with a slip ring 304 through the rotating part 306, the transverse rod 303 can be slidably mounted within the two slip rings 304. The transverse rod 303 can drive the mounting bracket 301 to descend, and then the side puncture needle 307 on the lower surface of the mounting bracket 301 can perform a puncture test on the edge of the PE film.

[0026] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
