Description

Technical Field

[0001] This invention relates to the field of plastic packaging bag testing technology, specifically to a new testing device for the production of plastic packaging bags. Background Technology

[0002] Plastic packaging bags are made from plastic granules, processed into films or bag-like structures, to wrap and protect goods, prevent crushing and contamination, and extend shelf life. They are mainly used in daily life and industrial production, and are widely used for packaging food, daily necessities, fertilizers, garbage bags, etc., with functions such as physical protection and product display.

[0003] Patent CN119147374A discloses a device for testing the toughness and strength of plastic packaging bags. The device includes a base plate with a support welded to its top. A test hydraulic cylinder is fixedly mounted on the top of the support. An upper pressing component is fixedly mounted at the bottom of the telescopic end of the test hydraulic cylinder, and a lower test component is fixedly mounted on the top of the base plate. This patent performs overall toughness and strength testing by placing the plastic packaging bag on top of the lower pressing plate, with two sets of upper and lower pressing plates clamping both ends of the bag. Alternatively, it performs single-sided toughness and strength testing by fitting the plastic packaging bag onto a test frame, with the test surface at the top. Adjusting the distance between the two sets of upper and lower pressing plates allows for toughness and strength testing of a single-sided coated area, providing comprehensive testing. The arc-shaped design of the test frame and test chute further enhances testing efficiency. However, this device has limitations in the direction of toughness and strength testing, making it difficult to simultaneously test laterally and longitudinally, leading to significant errors between the test data and actual application results. Therefore, this patent proposes a new testing device for the production of plastic packaging bags to address these issues. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a new testing device for the production of plastic packaging bags, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a testing device for the production of new material plastic packaging bags, comprising a frame, a worktable slidably connected to the inner wall of the frame, a stretching mechanism provided on the top surface of the worktable, a rear plate fixedly connected to the right side of the frame, a unloading mechanism provided in front of the rear plate, a motor fixedly connected to the inner wall of the frame, a collecting mechanism provided at the bottom of the worktable, a base fixedly connected to the bottom of the frame, and the stretching mechanism comprising a clamp, a clamping screw, a clamping gear, a clamping rack, and a stretching screw; the clamping screw is rotatably connected to the clamp, the clamping gear is fixedly connected to the top of the clamping screw, and the clamping rack is fixedly connected to the right side of the frame. The clamp is movably connected to the tension screw, which is rotatably connected to the right side of the frame. The clamp gear meshes with the clamp rack. The tension screw is rotatably connected to the rear plate, and the rear side of the clamp contacts the inner wall of the frame. The tensioning mechanism also includes a wedge block, a U-shaped plate, a discharge push plate, a spring telescopic rod, a return spring, and an extension plate. The wedge block is fixedly connected to the bottom of the clamp. The bottom of the return spring is fixedly connected to the worktable. The U-shaped plate is fixedly connected to the top of the return spring. The discharge push plate is fixedly connected to the worktable. The spring telescopic rod is fixedly connected to the inner wall of the discharge push plate. The extension plate is fixedly connected to the end of the spring telescopic rod away from the discharge push plate. The inclined block is slidably connected to the worktable, the U-shaped plate is slidably connected to the inner wall of the unloading push plate, and the unloading push plate is slidably connected to the inner wall of the clamp. The inner wall of the U-shaped plate and the unloading push plate are in contact with each other. When the device is started, the motor output end drives the clamp to slide to both sides of the worktable. At the same time, the tension screw rotates, driving the clamp to slide to both sides. The sliding of the clamp drives the clamp gear to slide to both sides. When the clamp gear slides into the working range of the clamp rack, the clamp gear meshes with the clamp rack and rotates. The rotation of the clamp gear drives the clamp screw to slide upward to open the clamp. When the clamp slides a certain distance to both sides, the clamp completes the upward stroke and slides downward. When the clamp slides away from the working range of the clamp rack, the device completes the loading process. The clamp begins the tensile test. When the test is complete, the tension screw rotates, causing the clamp to slide inward. The clamp then causes the inclined block to slide inward, which in turn causes the U-shaped plate to slide upward along the inclined plane. The upward sliding of the U-shaped plate causes the extension plate to slide to both sides along the inclined plane, pushing out any remaining waste material inside the clamp. This achieves stable clamping of the plastic packaging bag. At the same time, the moving worktable provides lateral and longitudinal tension during the test, allowing for multi-directional testing of the plastic packaging bag. This makes the test data more closely reflect actual usage effects and improves the testing effect of the device. As the U-shaped plate rises, the extension plate moves to both sides to push out any remaining waste material adhering to the clamp, preventing waste material from affecting the testing effect of the device.

[0006] Preferably, the unloading mechanism includes: an unloading rack, an unloading gear, a slanted sleeve, an unloading plate, an unloading screw, a rotating rod, a cross bar, and a barb. The unloading rack is fixedly connected to the worktable, the unloading screw is rotatably connected to the inner wall of the frame, the unloading gear is fixedly connected to the unloading screw, the slanted sleeve is movably connected to the unloading screw, the rotating rod is rotatably connected to the rear plate, the unloading plate is fixedly connected to the circumferential surface of the rotating rod, the cross bar is slidably connected to the inner wall of the slanted sleeve, the barb is fixedly connected to the circumferential surface of the slanted sleeve, the unloading gear meshes with the unloading rack, the right side of the unloading rack is slidably connected to the inner wall of the frame, the unloading plate is rotatably connected to the inner wall of the rear plate, and the cross bar is rotatably connected to the top of the unloading plate. While the tension spring slides upward, the U-shaped plate drives the U-shaped pull rod to slide upward. The U-shaped pull rod drives the base plate to rotate counterclockwise along the outer surface of the base plate's rotating shaft, concentrating the hanging waste material and preventing it from accumulating too high at the working position, which would affect the equipment test. When the test is completed, the tension screw continues to rotate, causing the clamp to slide to both sides. The clamp causes the inclined block to slide outward. The return spring rebounds, causing the U-shaped plate to slide downward to complete the reset. The spring extension rod rebounds, causing the unloading push plate to reset. The U-shaped plate drives the U-shaped pull rod to slide downward. The U-shaped pull rod slides downward, causing the base plate to rotate clockwise along the circumference of the base plate's rotating shaft, completing the reset and collecting the waste material after the test. The reciprocating rotation of the base plate can concentrate the waste material, preventing it from accumulating too high at the working position of the device and affecting subsequent test results.

[0007] Preferably, the collection mechanism includes a U-shaped pull rod, a pull rod shaft, a base plate, a base plate shaft, and a waste bin. The U-shaped pull rod is fixedly connected to the bottom of the U-shaped plate, the pull rod shaft is rotatably connected to the base plate, the base plate shaft is rotatably connected to the inner wall of the waste bin, the base plate is fixedly connected to the circumferential surface of the base plate shaft, the U-shaped pull rod is slidably connected to the inner wall of the workbench, the pull rod shaft is rotatably connected to the bottom end of the U-shaped pull rod, and the base plate is slidably connected to the inner wall of the waste bin. When the device is started, the motor output drives the workbench to slide to the left and right sides, the workbench drives the unloading rack to slide to the left, and when the unloading rack slides to the working position of the unloading gear, the unloading rack meshes with the unloading gear, the unloading rack drives the unloading gear to rotate counterclockwise, the unloading gear drives the unloading screw to rotate, and the rotation of the unloading screw drives the inclined top sleeve. The inclined sleeve slides upward, causing the cross rod to slide upward. When the inclined sleeve slides upward and rotates to the top of the unloading screw, the cross rod wraps the tested plastic packaging bag around its surface and is secured by the barb. As the unloading screw continues to rotate, the inclined sleeve slides downward, causing the unloading plate to rotate clockwise along the circumference of the unloading rod. When the cross rod contacts the top surface of the unloading plate, the barb rotates counterclockwise to release the plastic packaging bag. At the same time, the unloading plate continues to rotate, scraping off the plastic packaging bag wrapped around the cross rod, and the bag slides off the inclined surface of the unloading plate into the waste bin. This achieves automatic unloading of the packaging bag after testing by wrapping it around the cross rod and scraping it off the unloading plate by the rotating inclined sleeve. This completes the automatic unloading of the device, reducing the need for human labor and greatly improving the working efficiency of the device.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. Through the coordinated operation of the clamp, clamp screw, clamp gear, clamp rack, tension screw, wedge block, U-shaped plate, unloading push plate, spring telescopic rod, return spring, and extension plate, stable clamping of plastic packaging bags is achieved. At the same time, the moving worktable provides lateral and longitudinal tension during testing, enabling multi-directional testing of the plastic packaging bags. This makes the test data more consistent with actual usage effects and improves the testing effect of the device. As the U-shaped plate rises, the extension plate moves to both sides to push out any residual waste material adhering to the clamp, preventing the waste material from affecting the testing effect of the device.

[0009] 2. Through the coordinated operation of the unloading rack, unloading gear, inclined sleeve, unloading plate, unloading screw, rotating rod, cross rod, and barb, the packaging bag is automatically wrapped around the cross rod to complete the unloading after the test is completed. At the same time, the rotating inclined sleeve scrapes the packaging bag off the unloading plate, completing the automatic unloading of the device, reducing the participation of human resources and greatly improving the working efficiency of the device.

[0010] 3. Through the coordinated operation of the U-shaped tie rod, tie rod pivot, base plate, base plate pivot, and waste collection cabinet, the waste material after testing is collected. The reciprocating rotation of the base plate can concentrate the waste material, preventing it from accumulating too high at the working position of the device and affecting subsequent test results.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Please see Figures 1-9 One embodiment of the present invention is: a testing device for the production of new material plastic packaging bags, comprising a frame 1, a worktable 2 slidably connected to the inner wall of the frame 1, a tensioning mechanism 3 provided on the top surface of the worktable 2, a rear plate 4 fixedly connected to the right side of the frame 1, a discharge mechanism 5 provided in front of the rear plate 4, a motor 6 fixedly connected to the inner wall of the frame 1, a collecting mechanism 7 provided at the bottom of the worktable 2, and a base 8 fixedly connected to the bottom of the frame 1.

The positioning spring 310 and extension plate 311 provide stable clamping for the plastic packaging bag. Simultaneously, the moving worktable 2 provides lateral and longitudinal tension during testing, enabling multi-directional testing of the plastic packaging bag. This makes the test data more closely reflect actual usage effects, improving the testing effectiveness of the device. The inclined block 306 is fixedly connected to the bottom of the clamp 301, the bottom of the return spring 310 is fixedly connected to the worktable 2, the U-shaped plate 307 is fixedly connected to the top of the return spring 310, the unloading push plate 308 is fixedly connected to the worktable 2, and the spring telescopic rod 309 is fixedly connected to... The inner wall of the unloading push plate 308 is fixedly connected to the end of the spring telescopic rod 309 away from the unloading push plate 308. The inclined block 306 is slidably connected to the worktable 2. The U-shaped plate 307 is slidably connected to the inner wall of the unloading push plate 308. The unloading push plate 308 is slidably connected to the inner wall of the clamp 301. The inner wall of the U-shaped plate 307 is in contact with the unloading push plate 308. While the U-shaped plate 307 is raised, the extension plate 311 moves to both sides to push out the residual waste material stuck in the clamp 301, so as to avoid the waste material in the device from affecting the detection effect of the device.

[0015] The unloading mechanism 5 includes: an unloading rack 501, an unloading gear 502, a slanted sleeve 503, an unloading plate 504, an unloading screw 505, a rotating rod 506, a cross bar 507, and a hook 508. The unloading rack 501 is fixedly connected to the workbench 2. The unloading screw 505 is rotatably connected to the inner wall of the frame 1. The unloading gear 502 is fixedly connected to the unloading screw 505. The slanted sleeve 503 is movably connected to the unloading screw 505, enabling automatic unloading by wrapping the packaging bag around the cross bar 507 after testing. The rotating rod 506 is rotatably connected to the rear plate 4. 504 is fixedly connected to the circumferential surface of the rotating rod 506, the cross rod 507 is slidably connected to the inner wall of the inclined top sleeve 503, the barb 508 is fixedly connected to the circumferential surface of the inclined top sleeve 503, the unloading gear 502 meshes with the unloading rack 501, the right side of the unloading rack 501 is slidably connected to the inner wall of the frame 1, the unloading plate 504 is rotatably connected to the inner wall of the rear plate 4, the cross rod 507 is rotatably connected to the top of the unloading plate 504, and the rotating inclined top sleeve 503 scrapes the packaging bag off the unloading plate 504, completing the automatic unloading of the device, reducing the participation of human resources, and greatly improving the working efficiency of the device.

[0016] Working principle: When the device starts, the output end of motor 6 drives the clamp 301 to slide to both sides of the worktable 2. At the same time, the tension screw 305 rotates, driving the clamp 301 to slide to both sides. The sliding of the clamp 301 drives the clamp gear 303 to slide to both sides. When the clamp gear 303 slides into the working range of the clamp rack 304, the clamp gear 303 meshes with the clamp rack 304 and rotates. The rotation of the clamp gear 303 drives the clamp screw 302 to slide upward to open the clamp 301. When the clamp 301 slides a certain distance to both sides, the clamp 301 completes its upward stroke and slides downward. When the clamp 301 slides out of the working range of the clamp rack 304, the device completes the clamping and begins the tensile test. When the test is completed, the tension screw 305... The rotation causes the clamp 301 to slide inward, which in turn causes the inclined block 306 to slide inward. The inclined block 306 causes the U-shaped plate 307 to slide upward along the inclined plane. The upward sliding of the U-shaped plate 307 causes the extension plate 311 to slide to both sides along the inclined plane, pushing out the residual waste material in the clamp 301. This achieves stable clamping of the plastic packaging bag. At the same time, the moving worktable 2 provides lateral and longitudinal tension during testing, enabling multi-directional testing of the plastic packaging bag. This makes the test data more consistent with the actual use effect and improves the testing effect of the device. As the U-shaped plate 307 rises, the extension plate 311 moves to both sides to push out the residual waste material adhering to the clamp 301, so as to prevent the waste material in the device from affecting the testing effect.

[0017] While the U-shaped plate 307 slides upward to stretch the return spring 310, the U-shaped plate 307 drives the U-shaped pull rod 701 to slide upward. The U-shaped pull rod 701 drives the base plate 703 to rotate counterclockwise along the outer surface of the base plate pivot 704, collecting the hanging waste material and preventing it from accumulating too high at the working position, which would affect the equipment test. When the test is completed, the tension screw 305 continues to rotate, driving the clamp 301 to slide to both sides. The clamp 301 drives the inclined block 306 to slide outward. The return spring 310 rebounds, driving the U-shaped plate 307 to slide downward to complete the reset. The spring extension rod 309 rebounds, driving the unloading push plate 308 to reset. The U-shaped plate 307 drives the U-shaped pull rod 701 to slide downward. The U-shaped pull rod 701 slides downward, driving the base plate 703 to rotate clockwise along the circumferential surface of the base plate pivot 704 to complete the reset, collecting the waste material after the test. The reciprocating rotation of the base plate 703 can concentrate the waste material, preventing it from accumulating too high at the working position of the device and affecting the subsequent test results.

[0018] Please see Figures 1-9 Based on the above embodiments, in another embodiment of the present invention, the collection mechanism 7 includes a U-shaped pull rod 701, a pull rod pivot 702, a base plate 703, a base plate pivot 704, and a waste collection cabinet 705. The U-shaped pull rod 701 is fixedly connected to the bottom of the U-shaped plate 307 to collect the waste after testing. The pull rod pivot 702 is rotatably connected to the base plate 703, and the base plate pivot 704 is rotatably connected to the inner wall of the waste collection cabinet 705. The base plate 703 is fixedly connected to the circumferential surface of the base plate pivot 704. The U-shaped pull rod 701 is slidably connected to the inner wall of the workbench 2, and the pull rod pivot 702 is rotatably connected to the bottom end of the U-shaped pull rod 701. The base plate 703 is slidably connected to the inner wall of the waste collection cabinet 705. The reciprocating rotation of the base plate 703 can concentrate the waste and prevent the waste from accumulating too high at the working position of the device, which would affect the subsequent test results.

[0019] Working principle: When the device starts, the output end of motor 6 drives the worktable 2 to slide to the left and right. The worktable 2 drives the unloading rack 501 to slide to the left. When the unloading rack 501 slides to the working position of the unloading gear 502, the unloading rack 501 meshes with the unloading gear 502. The unloading rack 501 drives the unloading gear 502 to rotate counterclockwise. The unloading gear 502 drives the unloading screw 505 to rotate. The rotation of the unloading screw 505 drives the inclined top sleeve 503 to slide upward. The inclined top sleeve 503 drives the cross rod 507 to slide upward. When the inclined top sleeve 503 slides upward and rotates to the top of the unloading screw 505, the cross rod 507 wraps the tested plastic packaging bag to the surface and is fixed by the barb 508. As the unloading screw 505 continues to rotate, the inclined top sleeve 503 slides downward, causing the unloading plate 504 to rotate clockwise along the circumference of the unloading rod 506. When the cross rod 507 contacts the top surface of the unloading plate 504, the barb 508 rotates counterclockwise to release the plastic packaging bag from its fixation. At the same time, the unloading plate 504 continues to rotate, scraping off the plastic packaging bag wrapped around the cross rod 507, and it slides down the inclined surface of the unloading plate 504 into the waste bin 705. This achieves automatic unloading of the packaging bag wrapped around the cross rod 507 after the test is completed. Simultaneously, the rotating inclined top sleeve 503 scrapes the packaging bag off the unloading plate 504, completing the automatic unloading of the device, reducing the participation of human resources, and greatly improving the working efficiency of the device.
