Description

Technical Field

[0001] This utility model relates to the field of plastic processing and testing technology, specifically a device for testing the toughness of plastic sheets. Background Technology

[0002] Plastic sheets are a widely used material in many industries. They are popular due to their versatility, durability, and ability to adapt to various environmental conditions. During the production process, plastic sheets need to be tested for toughness. However, ordinary plastic flexibility testing devices can cause some problems when testing plastics. When testing some plastic parts, the plastic surface is too slippery and it is difficult to fix them well. This makes them prone to loosening after clamping and fixing, resulting in inaccurate test data.

[0003] To address the aforementioned issues, CN202222625098.2 discloses "An extrusion device for testing the flexibility of plastics." This device uses rubber anti-slip pads on opposite sides of two fixed plates to minimize loosening during the clamping of plastic parts, thus preventing interference with the testing process. However, this device still has certain drawbacks in practical use. For example, the height of the fixed plates is fixed, therefore it can only clamp and test plastic sheets at a fixed height.

Detailed Implementation

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-7 As shown, a plastic sheet toughness testing device includes: a base 1, two clamping plates 101 are provided on the top of the base 1, a top plate 102 is provided on the outer side of the clamping plates 101, and a testing component is provided on the back of the clamping plates 101 for detecting the bending angle of the plastic sheet. The testing component includes: a support plate 2, an electric telescopic rod a201, a side plate 202, a vertical plate 203, and a scale line 204. An adjustment component is provided at the bottom of the clamping plates 101 for adjusting the height of the clamping plates 101. The adjustment component includes: a rotating plate 3, an electric push rod 301, a lifting plate 302, a vertical plate 303, and a rotating rod 304.

[0024] The base 1 has a support plate 2 installed on one side of its top. An electric telescopic rod a201 is installed on the top of the support plate 2. A side plate 202 is installed on the top of the electric telescopic rod a201. A vertical plate 203 is installed on one side of the outer end of the side plate 202. A scale line 204 is set on one side of the outer end of the vertical plate 203. When the push plate 603 performs toughness testing on the plastic sheet, the bending of the plastic sheet can be measured through the scale line 204, which makes it easy for the staff to accurately know the bending angle of the plastic sheet and to calculate the toughness of the plastic sheet. When adjusting the clamping height of the plastic sheet, the side plate 202, the vertical plate 203 and the scale line 204 can be raised and lowered by the electric telescopic rod a201, thereby adjusting the working height of the scale line 204.

[0025] The base 1 has a rotating plate 3 on one side of its top. Electric push rods 301 are installed on both sides of the top of the rotating plate 3. A lifting plate 302 is installed at the top of the electric push rod 301. A vertical plate 303 is installed on one side of the top of the lifting plate 302. A rotating rod 304 is installed between the two vertical plates 303. Two clamping plates 101 are located outside the rotating rod 304. When it is necessary to adjust the height of the plastic sheet, the lifting plate 302, the vertical plate 303 and the rotating rod 304 can be raised and lowered by the electric push rod 301. Since the clamping plate 101 is installed outside the rotating rod 304, the rotating rod 304 can drive the clamping plate 101 to rise and fall, thereby adjusting the height of the clamping plate 101 to adapt to plastic sheets of different heights. When the lifting plate 302 rises and falls, it can slide outside the vertical rod 4 through the limiting hole 401. Therefore, the vertical rod 4 and the limiting hole 401 limit the lifting plate 302.

[0026] Four vertical rods 4 are installed between the top plate 102 and the rotating plate 3. A limit hole 401 is opened on one side of the top of the lifting plate 302. A motor a402 is installed on one side of the outer end of one of the vertical plates 303. The outer end of the motor a402 is connected to the rotating rod 304 through the motor shaft. One end of the rotating rod 304 is rotatably connected to another vertical plate 303 through a bearing. An adjustment hole 403 is opened on one side of the outer end of the clamping plate 101. When using the device, the plastic sheet to be tested is placed on the top of the top plate 102 and between the two clamping plates 101. Then, the motor a402 is used to move the plastic sheet between the two clamping plates 101. The 402 drive motor shaft drives the rotating rod 304 to rotate. Since the rotating rod 304 has two threads in opposite directions on its outer side, when the rotating rod 304 drives the threads to rotate, the clamping plate 101 is threadedly connected to the rotating rod 304 through the adjusting hole 403 and the threads. Therefore, the clamping plate 101 can move laterally through the adjusting hole 403 as the threads rotate. Since the two threads are in opposite directions, the two clamping plates 101 can move inward or outward through the two adjusting holes 403 and the two threads respectively until the plastic sheet is clamped and fixed between the two clamping plates 101.

[0027] The base 1 has a motor b5 installed at its bottom. A small gear 501 is connected to the top of the motor b5 via a motor shaft. A large gear 502 is meshed with one side of the small gear 501. A connecting rod 503 is installed on the top of the large gear 502. The top of the connecting rod 503 is connected to the rotating plate 3. When the material conveying plate needs to be rotated to pass through the other side for toughness testing, the motor b5 drives the motor shaft to rotate the small gear 501. The small gear 501 then drives the large gear 502 to rotate. The connecting rod 503 can drive the rotating plate 3, the vertical rod 4, and the top plate 102 to rotate. Since the plastic sheet is clamped and fixed on the top of the top plate 102, it can rotate, thereby adjusting the other side of the plastic sheet to be opposite to the push plate 603. A support rod is installed at the bottom of the large gear 502. The bottom end of the support rod is rotatably connected to the base 1 via a bearing. Therefore, the support rod can support the large gear 502. The bottom of the rotating plate 3 is equipped with four pulleys, which can support the rotating plate 3 and ensure that the rotating plate 3 can rotate.

[0028] The base 1 has a fixed plate 6 installed on one side of its top. A movable block 601 is provided on one side of the outer end of the fixed plate 6. An electric telescopic rod b602 is installed on one side of the outer end of the movable block 601. A push plate 603 is installed on one end of the electric telescopic rod b602. When it is necessary to test the toughness of the plastic sheet, the push plate 603 is moved towards the plastic sheet by the electric telescopic rod b602. Then, the push plate 603 squeezes the plastic sheet, causing the plastic sheet to bend, thus testing the toughness of the plastic sheet.

[0029] An electric telescopic rod c7 is installed on one side of the outer end of the fixed plate 6. The top of the electric telescopic rod c7 is connected to the movable block 601. A through groove 701 is opened on the outer end of the fixed plate 6. Two uprights 702 are installed inside the through groove 701. Limiting blocks 703 are connected to both sides of the outer end of the electric telescopic rod b602. An opening 704 is opened on the top of the limiting block 703. When the height of the push plate 603 needs to be adjusted, the movable block 601, the electric telescopic rod b602, and the push plate 603 are raised and lowered by the electric telescopic rod c7, thereby adjusting the height of the push plate 603. When the electric telescopic rod b602 is raised and lowered, it will drive the limiting block 703 to rise and fall. The limiting block 703 can slide on the outside of the upright 702 through the opening 704. Therefore, the limiting block 703 and the electric telescopic rod b602 can be limited by the upright 702 and the opening 704, thereby preventing the electric telescopic rod b602 from deviating during raising and lowering.

[0030] Working principle:

[0031] When using this device, the plastic sheet to be tested is placed on top of the top plate 102, between the two clamping plates 101. Then, the motor shaft is driven by motor a402 to rotate the rotating rod 304. Since the rotating rod 304 has two threads in opposite directions on its outer side, when the rotating rod 304 rotates the threads, the clamping plates 101, connected to the rotating rod 304 via adjusting holes 403 and threads, can move laterally through the adjusting holes 403 as the threads rotate. Because the two threads are in opposite directions, the two clamping plates 101 can move inwards or outwards through the two adjusting holes 403 and the two threads, respectively, until the plastic sheet is clamped and fixed between the two clamping plates 101. The push plate 603 is then moved towards the plastic sheet via the electric telescopic rod b602. The plastic sheet is moved and then squeezed by the push plate 603, causing it to bend. This allows for the testing of the plastic sheet's toughness. The bending of the plastic sheet is measured by the scale line 204, enabling staff to accurately determine the bending angle and calculate the toughness. Furthermore, the electric telescopic rod a201 can be used to raise and lower the side plate 202, vertical plate 203, and scale line 204 to adjust the height of the scale line 204, which is adjusted by the electric push rod 301. The electric push rod 301 can also raise and lower the lifting plate 302, vertical plate 303, and rotating rod 304. Since the clamping plate 101 is installed outside the rotating rod 304, the rotating rod 304 can raise and lower the clamping plate 101, thus adjusting its height.
