Description

Technical Field

[0001] This utility model belongs to the field of plastic product testing technology, specifically relating to a strength testing device for biodegradable plastic products. Background Technology

[0002] The application of biodegradable plastic products is becoming increasingly widespread, covering packaging, tableware, agricultural films, medical equipment and other fields. Compared with traditional plastics, although biodegradable plastics have environmentally friendly characteristics, their performance, especially mechanical strength, durability and degradation rate, are still key indicators for evaluating whether they meet industrial standards and actual use requirements. Therefore, researching and testing the physical and mechanical properties of biodegradable plastic products, especially their strength, is crucial to ensuring their reliability and safety in application.

[0003] A prior art patent, CN215339295U, describes a strength testing device for biodegradable plastic products. This patent includes a base plate, with a housing fixedly connected to the bottom of the base plate via a bracket. A first motor is fixedly connected to the right side of the housing. The left end of the first motor's shaft penetrates into the inner cavity of the housing and is fixedly connected to a first threaded rod. The left end of the first threaded rod is movably connected to the left side of the inner cavity of the housing via a bearing. Connecting plates are threaded onto the surfaces of both ends of the first threaded rod. The end of the connecting plate furthest from the first threaded rod passes through the housing and the base plate and is fixedly connected to a transparent cover… This device solves the problem of existing devices being inconvenient for fixing plastic products of different thicknesses. However, in practical use, it still has the following shortcomings: In practice, after the strength test is completed, the plastic parts remain on the placement plate, requiring manual unloading, resulting in low testing efficiency. Furthermore, the device cannot automatically separate qualified and unqualified plastic parts for separate storage after testing.

[0004] Therefore, a biodegradable plastic product strength testing device is needed to solve the problems of low efficiency in manual material feeding and testing and the inability to automatically divide and store unqualified plastic parts in the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide a strength testing device for biodegradable plastic products to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a strength testing device for biodegradable plastic products, comprising a base, a testing platform fixedly connected to the top of the base, multiple support columns fixedly connected to the top of the base, a top plate fixedly connected to the top of the multiple support columns, a hydraulic cylinder fixedly connected to the top of the top plate near the front end, a connecting plate fixedly connected to the output end of the hydraulic cylinder through the top plate, two limiting rods fixedly connected to the top of the connecting plate, a hardness tester fixedly connected to the bottom of the connecting plate near the front end, a pressure plate fixedly connected to the bottom of the hardness tester, a feeding mechanism provided on the top of the base, a partitioning mechanism provided at the front end of the testing platform, and a first collection box and a second collection box placed on the top of the base near the front end.

[0007] It should be noted in the solution that a shock-absorbing pad is fixedly connected to the bottom of the base.

[0008] It is worth noting that baffles are fixedly connected to the top of the testing platform near both sides.

[0009] It should be further noted that the top plate has two through holes corresponding to the limiting rod.

[0010] In a preferred embodiment, the feeding mechanism includes a connecting column fixedly connected to the bottom of the connecting plate near the rear end. A mounting base is fixedly connected to the bottom of the connecting column. A wedge-shaped rotating plate is rotatably connected to the outside of the mounting base. A stop post is fixedly connected to the outside of the mounting base near the bottom. A convex frame is fixedly connected to the top of the base. A first slide rod is slidably connected to the rear end of the convex frame. A second slide rod is fixedly connected to the front end of the first slide rod. A spring is sleeved on the outer wall of the second slide rod. A guide post is fixedly connected to the rear end of the first slide rod. A push plate is fixedly connected to the front end of the second slide rod.

[0011] In a preferred embodiment, the second slide rod is slidably connected to the front end of the convex frame, and the spring is fixedly connected between the front end of the first slide rod and the rear surface of the front end of the convex frame.

[0012] In a preferred embodiment, the partitioning mechanism includes a feeding trough fixedly connected to the front end of the testing table, a first partition plate fixedly connected to one side of the top of the feeding trough, a second partition plate fixedly connected to the other side of the top of the feeding trough, a rotating shaft rotatably connected to the top of the feeding trough near the middle, a guide plate fixedly connected to the outer wall of the rotating shaft, and a servo motor fixedly connected to the bottom of the feeding trough.

[0013] In a preferred embodiment, the output end of the servo motor passes through the bottom of the feeding trough and is fixedly connected to the rotating shaft.

[0014] Compared with the prior art, the strength testing device for biodegradable plastic products provided by this utility model has at least the following beneficial effects:

[0015] (1) By setting up a feeding mechanism, the hydraulic cylinder drives the connecting plate to descend during the test, so that the pressure plate descends and cooperates with the hardness tester to test the strength of the plastic parts. At the same time as the connecting plate descends, the mounting base descends. Under the action of the stop column, the wedge-shaped rotating plate can only rotate in one direction. When the test is completed, the hydraulic cylinder retracts and drives the connecting plate to rise, and the mounting base rises accordingly. Since the wedge-shaped rotating plate cannot rotate downward, the wedge-shaped rotating plate generates a thrust on the guide column, pushing the guide column forward. This causes the second slide rod to drive the push plate forward, pushing the plastic parts on the top of the test table forward, completing the automatic feeding and improving the efficiency of the test work.

[0016] (2) By setting up a partitioning mechanism, after the detected plastic parts are automatically pushed into the feeding trough, the servo motor receives the instruction from the control system according to the detection result. When the plastic parts are qualified, the servo motor drives the guide plate to rotate clockwise, so that the qualified plastic parts fall into the first collection box for collection. When the plastic parts are unqualified, the servo motor drives the guide plate to rotate counterclockwise, so that the unqualified plastic parts fall into the second collection box for collection, which facilitates subsequent management and processing.

[0023] The present invention will be further described below with reference to the embodiments.

[0024] Please see Figure 1-5 This utility model provides a strength testing device for biodegradable plastic products, including a base 1, a testing platform 2 fixedly connected to the top of the base 1, multiple support columns 3 fixedly connected to the top of the base 1, a top plate 4 fixedly connected to the top of the multiple support columns 3, a hydraulic cylinder 5 fixedly connected to the top of the top plate 4 near the front end, a connecting plate 6 fixedly connected to the output end of the hydraulic cylinder 5 through the top plate 4, two limiting rods 7 fixedly connected to the top of the connecting plate 6, a hardness tester 8 fixedly connected to the bottom of the connecting plate 6 near the front end, a pressure plate 9 fixedly connected to the bottom of the hardness tester 8, a feeding mechanism 10 provided on the top of the base 1, a partitioning mechanism 11 provided at the front end of the testing platform 2, and a first collection box 12 and a second collection box 13 placed on the top of the base 1 near the front end.

[0025] Further as Figure 1 and Figure 2 As shown, it is worth noting that the bottom of the base 1 is fixedly connected with a shock-absorbing pad. The shock-absorbing pad can effectively absorb the vibration generated by the base 1 during operation, reduce the impact of vibration on other parts of the equipment, especially the impact on the precision testing component hardness tester 8, and maintain the stable operation of the equipment.

[0026] Further as Figure 1 and Figure 2 As shown, it is worth noting that baffles are fixedly connected to the top of the testing platform 2 near both sides. The baffles can prevent the plastic products from shifting or sliding during the test, ensuring that the test object remains in the predetermined position during the test. This helps to improve the accuracy and stability of the test and prevents errors in the test results due to displacement of the plastic products.

[0027] Further as Figure 1 and Figure 2 As shown, it is worth noting that the top plate 4 has two through holes corresponding to the limit rod 7. The through holes limit and guide the limit rod 7, thereby making the lifting and lowering of the connecting plate 6 driven by the hydraulic cylinder 5 more stable.

[0028] Further as Figure 3As shown, it is worth noting that the unloading mechanism 10 includes a connecting column 1001 fixedly connected to the bottom of the connecting plate 6 near the rear end. A mounting base 1002 is fixedly connected to the bottom of the connecting column 1001. A wedge-shaped rotating plate 1003 is rotatably connected to the outside of the mounting base 1002. A stop post 1004 is fixedly connected to the outside of the mounting base 1002 near the bottom. A convex frame 1005 is fixedly connected to the top of the base 1. A first slide rod 1006 is slidably connected to the rear end of the convex frame 1005. A second slide rod 1007 is fixedly connected to the front end of the first slide rod 1006. A spring 1008 is sleeved on the outer wall of the second slide rod 1007. A guide post 1009 is fixedly connected to the rear end of the first slide rod 1006. A push plate 1010 is fixedly connected to the front end of the second slide rod 1007. By setting up the unloading mechanism, the second slide rod 1007 drives the push plate 1010 to push forward, pushing the plastic parts on the top of the inspection table 2 forward, completing the automatic unloading and improving the efficiency of the inspection work.

[0029] Further as Figure 3 As shown, it is worth noting that the second slide rod 1007 is slidably connected to the front end of the convex frame 1005, and the spring 1008 is fixedly connected between the front end of the first slide rod 1006 and the rear surface of the front end of the convex frame 1005, ensuring that the first slide rod 1006 and the second slide rod 1007 can only move back and forth in the horizontal direction. At the same time, the spring 1008 provides a reset capability for the first slide rod 1006.

[0030] As can be seen from the above working process, by setting up a feeding mechanism, the second slide bar 1007 drives the push plate 1010 to push forward, pushing the plastic parts on the top of the inspection table 2 forward, completing the automatic feeding and improving the efficiency of the inspection work.

[0031] Further as Figure 4 and Figure 5 As shown, it is worth noting that the partitioning mechanism 11 includes a feeding trough 1101 fixedly connected to the front end of the inspection table 2. A first partition plate 1102 is fixedly connected to the top of the feeding trough 1101 near one side, and a second partition plate 1103 is fixedly connected to the top of the feeding trough 1101 near the other side. A rotating shaft 1104 is rotatably connected to the top of the feeding trough 1101 near the middle. A guide plate 1105 is fixedly connected to the outer wall of the rotating shaft 1104. A servo motor 1106 is fixedly connected to the bottom of the feeding trough 1101. By setting up the partitioning mechanism 11, qualified plastic parts fall into the first collection box 12 for collection, and unqualified plastic parts fall into the second collection box 13 for collection, which facilitates subsequent management and processing.

[0032] Further as Figure 4 and Figure 5As shown, it is worth noting that the output end of the servo motor 1106 passes through the bottom of the feeding trough 1101 and is fixedly connected to the rotating shaft 1104, ensuring that the servo motor 1106 can drive the rotating shaft 1104 to rotate, thereby providing driving force for the displacement of the guide plate 1105.

[0033] This solution has the following working process: In actual use, the plastic part to be tested is placed on top of the testing table 2. The hydraulic cylinder 5 is opened, causing the connecting plate 6 to descend, so that the pressure plate 9 descends and cooperates with the hardness tester 8 to perform strength testing on the plastic part. Simultaneously, the connecting plate 6 descends, causing the mounting base 1002 to descend. Under the action of the stop post 1004, the wedge-shaped rotating plate 1003 can only rotate in one direction. When the test is completed, the hydraulic cylinder 5 retracts, causing the connecting plate 6 to rise, and the mounting base 1002 follows suit. Since the wedge-shaped rotating plate 1003 cannot rotate downwards, it exerts a thrust on the guide post 1009, pushing the guide post 1009... The column 1009 moves forward, causing the second slide bar 1007 to drive the push plate 1010 forward, pushing the plastic part on the top of the inspection table 2 forward. After the inspected plastic part is automatically pushed into the feeding trough 1101, the servo motor 1106 receives the instruction from the control system according to the inspection result. When the plastic part is qualified, the servo motor 1106 drives the guide plate 1105 to rotate clockwise, so that the qualified plastic part falls into the first collection box 12 for collection. When the plastic part is unqualified, the servo motor 1106 drives the guide plate 1105 to rotate counterclockwise, so that the unqualified plastic part falls into the second collection box 13 for collection.

[0034] In summary: By setting up a feeding mechanism, the second slide bar 1007 drives the push plate 1010 forward, pushing the plastic parts on the top of the inspection table 2 forward, completing automatic feeding and improving the efficiency of the inspection work; by setting up a partitioning mechanism 11, qualified plastic parts fall into the first collection box 12 for collection, and unqualified plastic parts fall into the second collection box 13 for collection, which facilitates subsequent management and processing.
