Abstract
Description
Technical Field
[0001] This utility model relates to the field of membrane material sampling technology, specifically to a cutting and sampling device for rolling membrane materials into a circle. Background Technology
[0002] In membrane material production, after the membrane material is rolled into a circle, such as in the production of EVA membrane, it is necessary to take samples from the membrane roll for performance testing. Currently, the technology usually involves manually cutting a sample along the width of the membrane roll with a knife. However, since some membrane rolls are quite wide, the cut samples are quite long. When cutting manually, they are easy to fall onto the machine frame or the ground and get oily, which affects the performance test results. Utility Model Content
[0003] To address the shortcomings of the existing technology, this utility model proposes a cutting and sampling device for rolling up membrane materials.
[0004] To achieve the above-mentioned technical effects, the present invention adopts the following solution:
[0005] A cutting and sampling device for rolling a film material includes a support frame located above a rolling shaft. At least two cylinders are mounted on the support frame along the length of the rolling shaft. The telescopic rods of the cylinders extend downwards and are connected to a vertically arranged vacuum tube. The upper and lower ends of the vacuum tube are connected. A connector is located at the upper end of the vacuum tube. A guide rail parallel to the rolling shaft is located at the lower end of the support frame. The guide rail is positioned on one side of the line connecting the at least two cylinders. A sliding movable seat is fitted on the guide rail. The movable seat is driven to slide by a driving mechanism. A downwardly extending blade is fixed on the movable seat, and the blade is positioned close to the vacuum tube.
[0006] In a preferred embodiment, the cylinder's telescopic rod is fixedly provided with a first connecting block and a second connecting block spaced apart in the vertical direction. Both the first and second connecting blocks have vertically penetrating guide holes. The vacuum tube is slidably disposed through the two guide holes. A first limiting block located above the first connecting block and a second limiting block located below the second connecting block are fixedly provided on the vacuum tube. A spring is sleeved on the vacuum tube, and the upper and lower ends of the spring are respectively connected to the second connecting block and the second limiting block.
[0007] In a preferred embodiment, the driving mechanism includes a lead screw rotatably mounted on a support frame, the lead screw passing through a movable seat and threadedly connected to the movable seat, and a motor connected to one end of the lead screw.
[0008] In a preferred embodiment, the lower end of the vacuum tube is provided with a rubber head, and the lower end of the rubber head is provided with a vacuum hole communicating with the vacuum tube.
[0009] In a preferred embodiment, the blade is fitted with a detachable blade cover.
[0010] Compared with existing technologies, the beneficial effects are:
[0011] This invention has a simple structure and is easy to use. The cylinder drives the vacuum tube to descend and press against the membrane roll. The membrane at the end is held in place by vacuum adsorption. Then, the cylinder lifts the membrane to the height of the blade. The blade moves from one side of the membrane to the other side on the guide rail, thereby cutting the membrane for sampling. Because the membrane is lifted by the vacuum tube, the sample will not fall to the ground or the frame, ensuring the cleanliness of the sample. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] A cutting and sampling device for rolling a film material includes a support frame 1 located above a rolling shaft, on which the film material is rolled. At least two cylinders 2 are mounted on the support frame 1 along the length of the rolling shaft. The telescopic rods of the cylinders 2 extend downwards and are connected to vertically arranged vacuum tubes 3. The upper and lower ends of the vacuum tubes 3 are connected. Specifically, the lower end of the vacuum tube 3 is located directly above the central axis of the rolling shaft. The upper end of the vacuum tube 3 is provided with a connector 8, which connects to an external vacuum generator. The lower end of the support frame 1 is provided with a guide rail 11 parallel to the rolling shaft. The guide rail 11 is located on one side of the line connecting the at least two cylinders 2. A sliding movable seat 13 is matched on the guide rail 11. The movable seat 13 is driven to slide by a driving mechanism. A downwardly extending blade 14 is fixed on the movable seat 13, and the blade 14 is positioned close to the vacuum tube 3.
[0017] After the membrane is rolled into a circle, cylinder 2 drives vacuum tube 3 to descend and press against the membrane roll. Vacuum adsorption holds the end of the membrane. Then, driven by cylinder 2, the membrane is lifted to the height of blade 14. Blade 14 moves from one side of the membrane to the other side on guide rail 11, thereby cutting the membrane for sampling. Because the membrane is lifted by vacuum tube 3, the sample will not fall to the ground or the frame, ensuring the cleanliness of the sample.
[0018] In a preferred embodiment, the telescopic rod of the cylinder 2 is fixedly provided with a first connecting block 4 and a second connecting block 5 that are spaced apart in the vertical direction. Both the first connecting block 4 and the second connecting block 5 are provided with vertically penetrating guide holes. The vacuum tube 3 is slidably disposed through the two guide holes. A first limiting block 6 located above the first connecting block 4 and a second limiting block 7 located below the second connecting block 5 are fixedly provided on the vacuum tube 3. A spring 9 is sleeved on the vacuum tube 3, and the upper and lower ends of the spring 9 are respectively connected to the second connecting block 5 and the second limiting block 7.
[0019] The vacuum tube 3 slides on the first connecting block 4 and the second connecting block 5. The vacuum tube 3 is pushed downward by the elastic force of the spring 9 and is limited by the first limiting block 6, so that the vacuum tube 3 can be buffered when it comes into contact with the film roll.
[0020] In a preferred embodiment, the driving mechanism includes a lead screw 15 rotatably mounted on a support frame 1. The lead screw 15 passes through a movable seat 13 and is threadedly connected to the movable seat 13. One end of the lead screw 15 is connected to a motor 12. The motor 12 drives the lead screw 15 to rotate, thereby driving the movable seat 13 to move on the guide rail 11.
[0021] In a preferred embodiment, the lower end of the vacuum tube 3 is provided with a rubber head 10, and the lower end of the rubber head 10 has a vacuum hole communicating with the vacuum tube 3. The rubber material is soft, making it more suitable for sealing contact with the membrane material, and avoiding scratches on the membrane material caused by hard contact between the vacuum tube 3 and the membrane material.
[0022] In a preferred embodiment, the blade 14 is fitted with a removable blade cover. When not in use, the blade cover is placed over the blade 14 for protection.
