Description

Technical Field

[0001] This utility model relates to the field of cast film technology, specifically a cast film tensile testing device with a waste collection structure. Background Technology

[0002] Cast film is a type of film made through a casting process, which involves extruding molten plastic resin through a precisely controlled mold and rapidly cooling and solidifying it into a film. Tensile testing is required during the casting film processing. The main reason for conducting tensile testing on cast film is to evaluate its mechanical properties and ensure product quality and safety.

[0003] A search revealed that existing technologies, such as the protective film tensile testing machine (publication number CN212989039U), include a testing platform, lifting components, clamping components, and clamps. The placement of positioning holes and latching slots, along with the positioning posts, latching parts, and elastic clamping strips, allows operators to quickly position the clamps at the predetermined installation position on the testing platform. Then, tightening the clamps secures the clamps, effectively improving the operator's clamp installation efficiency. When the clamp installation position needs adjustment, simply loosening the clamps allows the operator to rotate and adjust the clamps without completely disassembling them, ensuring the protective film maintains a high degree of surface flatness before tensile testing. This significantly speeds up the clamp adjustment process. The rounded corners and curved surfaces of the clamps prevent stress concentration between the protective film and the edges of the slider and clamping parts, improving the clamping reliability of the protective film.

[0004] In summary, existing tensile testing machines have improved the clamping reliability of the clamping components for the protective film, but they cannot collect the waste generated during the testing process. Therefore, a cast film tensile testing device with a waste collection structure is proposed. Utility Model Content

[0009] Preferably, the second clamping mechanism has the same structure as the first clamping mechanism.

[0010] The above technical solution facilitates the clamping of the cast film.

[0015] Preferably, the lead screw mechanism is located inside the protective cover, and a movable opening for use with a scraper is provided on one side of the protective cover.

[0016] The above technical solution avoids contact between the cast film and the lead screw mechanism.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a casting film tensile testing device with a waste collection structure, based on... Figure 1 and Figure 2 As shown, a first clamping mechanism 2 is fixedly installed on the top of the operating table 1, and a second clamping mechanism 3 is provided above the operating table 1 to cooperate with the first clamping mechanism 2. The second clamping mechanism 3 is connected to the moving mechanism 5 through two sets of connecting rods 4, and the moving mechanism 5 is installed on the top of the inner side of the fixed frame 6.

[0025] Specifically, the first clamping mechanism 2 includes a mounting block 201, and a bidirectional lead screw mechanism 202 is rotatably installed inside the mounting block 201. A first drive motor 2021 is installed on the outside of the mounting block 201 to drive the bidirectional lead screw mechanism 202 to rotate. The bidirectional lead screw mechanism 202 is connected to two sets of drive blocks 203, and the drive blocks 203 are connected to the clamping plate 205 installed on the outside of the mounting block 201 through a connecting block 204. The mounting block 201 is provided with a movable through groove that cooperates with the connecting block 204 to improve the stability of the mounting block 201 when it moves. A rubber anti-slip layer is fixedly installed on the inner side of the clamping plate 205 to improve the anti-slip effect during clamping.

[0026] To further explain, the second clamping mechanism 3 has the same structure as the first clamping mechanism 2.

[0027] Specifically, the moving mechanism 5 includes a bottom opening groove 501, which is fixedly installed on the top of the inner side of the fixed frame 6. A moving block 502 is slidably arranged inside the bottom opening groove 501, and the moving block 502 is connected to the connecting rod 4. An electric telescopic rod 503 that drives the moving block 502 to move is arranged inside the bottom opening groove 501.

[0028] In use, the two ends of the cast film are placed inside the two sets of clamping plates 205. The first drive motor 2021 is turned on. Under the action of the first drive motor 2021, the bidirectional lead screw mechanism 202 rotates, thereby driving the two sets of drive blocks 203 and clamping plates 205 to move closer and closer, thereby clamping and fixing the clamping plates 205 placed inside, and clamping the two ends of the cast film. After clamping, the electric telescopic rod 503 is turned on. Under the action of the electric telescopic rod 503, the moving block 502 drives the second clamping mechanism 3 to move, thereby stretching one end of the cast film through the second clamping mechanism 3 to detect the tensile force.

[0029] according to Figure 1 and Figure 3-4 As shown, a through slot is provided on the operating table 1, and a collection cover 7 is fixedly installed inside the through slot. The collection cover 7 is connected to the collection box 702 through a conveying pipe 701. A fan 703 is installed on one side inside the collection box 702, and a baffle 704 is provided on one side of the fan 703. A movable scraper mechanism 8 that works in conjunction with the baffle 704 is installed inside the collection box 702.

[0030] To further explain, by setting the baffle 704, contact between the cast film and the fan 703 can be avoided.

[0031] Specifically, the movable scraper mechanism 8 includes a scraper 801, one end of which is connected to a positioning block 802. The positioning block 802 is connected to a lead screw mechanism 803, and one end of the lead screw mechanism 803 is connected to a second drive motor 804.

[0032] In a further embodiment, the lead screw mechanism 803 is located inside the protective cover 8031, and a movable opening for use with the scraper 801 is provided on one side of the protective cover 8031. The lead screw mechanism 803 and the inner side of the protective cover 8031 ​​are rotatably connected. By setting the protective cover 8031, the casting film can be prevented from contacting the protective cover 8031.

[0033] After the test is completed, the first clamping mechanism 2 and the second clamping mechanism 3 are no longer clamping the cast film. At this time, the blower 703 is turned on. The blower 703 generates air force to draw the cast film into the collection hood 7 and into the collection box 702 through the delivery pipe 701 for collection. At the same time as the blower 703 is turned on, the second drive motor 804 is turned on, thereby driving the lead screw mechanism 803 to rotate. Under the action of the rotation of the lead screw mechanism 803, the positioning block 802 and the scraper 801 are moved. The scraper 801 pushes the cast film adsorbed on the baffle 704, thereby ensuring the flow of gas.
