Abstract

This invention discloses a degradation performance testing device for degradation masterbatch, specifically relating to the field of degradation performance testing technology. It includes a fixed platform, a pressing component positioned in the middle of the fixed platform, and testing components symmetrically arranged below the pressing component. A flipping component is located behind each of the two testing components, and a cleaning component is located at the top of each of the two testing components. This device uses the cooperation between the pressing and testing components to perform pressing tests on degradation masterbatches with different degradation times, quickly determining whether the degraded masterbatch meets the qualification standard. After the test, the two platforms simultaneously flip outwards via the flipping components, causing the degradation masterbatch on the platforms to automatically slide off. This avoids the tedious manual unloading operation, reduces labor intensity, and effectively prevents unnecessary damage or contamination of the degradation masterbatch during unloading, thus improving work efficiency.

Description

Technical Field

[0001] This invention relates to the field of degradation performance testing technology, and in particular to a degradation performance testing device for degradation masterbatch. Background Technology

[0002] In today's context of increasing environmental awareness, biodegradable materials have received widespread attention and application because they can gradually decompose in the natural environment, reducing pollution. As an important component of biodegradable materials, biodegradable masterbatch is widely used in the production of plastic products to give them biodegradable properties.

[0003] However, existing degradation performance testing methods for degradation masterbatches have many shortcomings. Traditional testing methods often rely on complex and time-consuming experimental processes, requiring the testing of a large number of samples. After each test, samples must be manually removed, and operators need to frequently bend over, reach out, and perform other repetitive actions. Especially when the number of samples is large and the number of test batches is frequent, this will greatly increase the physical exertion of operators, leading to a significant increase in labor intensity. Long-term operation may cause physical fatigue or even strain.

[0004] Chinese Patent Publication No. CN215414944U discloses a versatile in vitro dynamic simulation testing device for biodegradability, comprising: a constant temperature chamber with a door at its front end; support plates on both sides of the chamber, with a reflux pipe on one side; an outlet pipe on the outer wall of the reflux pipe, with an inlet pipe above it; a control pump at the front end of the inlet pipe; a sealing cap above the reflux pipe; and a fastening plate on one side of the fastening screw. Compared to existing devices, this versatile in vitro dynamic simulation testing device for biodegradability, through the reflux pipe, allows the test solution in the test tube to flow into the reflux pipe through the outlet pipe. Under the action of the control pump, the test solution in the reflux pipe can then be reintroduced into the test tube through the inlet pipe, thus providing a simulation of a dynamic environment.

[0005] However, the aforementioned device cannot automatically collect the degraded masterbatch after the test is completed, and manual unloading is very cumbersome. Utility Model Content

[0006] The main objective of this invention is to provide a degradation performance testing device for degradation masterbatch, which can effectively solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A degradation performance testing device for degradation masterbatch includes a fixed platform, a support leg fixedly connected to the lower end of the fixed platform, an extrusion assembly disposed in the middle of the fixed platform, test assemblies symmetrically disposed on the lower side of the extrusion assembly, a flipping assembly disposed on the rear side of each of the two test assemblies, and a cleaning assembly disposed on the upper end of each of the two test assemblies.

[0009] Preferably, the extrusion assembly includes a hydraulic device fixedly installed on the fixed platform, the output end of the hydraulic device is fixedly connected to a connecting frame, and the lower end of the connecting frame is fixedly connected to two extrusion plates.

[0010] Preferably, the test assembly includes a fixed base fixedly connected to the left side of the upper end of the fixed platform, a support platform is provided at the upper end of the fixed base, three springs are fixedly connected to the right side of the lower end of the support platform, the lower ends of the three springs are fixedly connected to the fixed platform, and the lower end of the extrusion plate is in contact with the upper end of the support platform.

[0011] Preferably, the flipping assembly includes a sliding frame fixedly connected to the rear end of the left-side extrusion plate, the outer surface of the sliding frame being slidably connected to the fixed platform, a rack being fixedly connected to the outer surface of the sliding frame, a gear being meshed with the outer surface of the rack, and the rear end of the gear being rotatably connected to the fixed platform.

[0012] Preferably, the inner surface of the gear is rotatably connected to a one-way rotating shaft, the inner surface of the one-way rotating shaft is fixedly connected to a rotating shaft, the outer surface of the rotating shaft is fixedly connected to a support platform, and the front end of the rotating shaft is rotatably connected to a fixed platform.

[0013] Preferably, the cleaning component includes sliding grooves on the front and rear sides of the upper end of the support platform, with a sliding seat slidably connected to the inner surfaces of the two sliding grooves, and a push plate fixedly connected to the outer surface of the sliding seat.

[0014] Preferably, the bottom end of the push plate is slidably connected to the inner wall of the support platform, and a handle is fixedly connected to the upper end of the sliding seat.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model uses the combination of the extrusion component and the testing component to perform a pressing test on degradation masterbatches with different degradation times. Under the same conditions, the two can be directly compared to quickly determine whether the degradation masterbatches have met the qualification standards. After the test, the two support platforms are flipped outwards simultaneously by the flipping component, causing the degradation masterbatches on the support platforms to slide off automatically. This avoids the tedious operation of manual unloading, reduces the contact between operators and degradation masterbatches, reduces labor intensity, and also effectively prevents unnecessary damage or contamination to degradation masterbatches during unloading, thus improving work efficiency.

[0017] This utility model uses a cleaning component to scrape off the degradation masterbatch adhering to the support platform, ensuring that the support platform is clean and tidy for the next use, avoiding interference from residual degradation masterbatch in subsequent tests, ensuring the reliability of test results, and extending the service life of the device.

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0025] Example 1, as Figure 1-5 As shown, a degradation performance testing device for degradation masterbatch includes a fixed platform 1, a support leg 11 fixedly connected to the lower end of the fixed platform 1, an extrusion component 2 arranged in the middle of the fixed platform 1, test components 3 symmetrically arranged on the lower side of the extrusion component 2, a flipping component 4 arranged on the rear side of each of the two test components 3, and a cleaning component 5 arranged on the upper end of each of the two test components 3.

[0026] The extrusion component 2 and the test component 3 mentioned above can press the degraded masterbatch together to quickly assess the mechanical property degradation caused by degradation. The main tests are: whether the compressive strength decreases and it is easier to crush; whether the brittleness increases and the fragmentation morphology changes from large pieces to powder; and whether the elasticity is lost and the deformation cannot be recovered. This comparison can indirectly reflect the damage of degradation to the material structure.

[0027] The extrusion assembly 2 includes a hydraulic device 21 fixedly installed on the fixed platform 1. The output end of the hydraulic device 21 is fixedly connected to a connecting frame 22, and the lower end of the connecting frame 22 is fixedly connected to two extrusion plates 23.

[0028] The test assembly 3 includes a fixed base 31 fixedly connected to the left side of the upper end of the fixed platform 1. A support platform 32 is provided at the upper end of the fixed base 31. Three springs 33 are fixedly connected to the right side of the lower end of the support platform 32. The lower ends of the three springs 33 are fixedly connected to the fixed platform 1. The lower end of the extrusion plate 23 is in contact with the upper end of the support platform 32.

[0029] Furthermore, the two support platforms 32 mentioned above are used to place degradation masterbatches with different degradation times. Then, the hydraulic device 21 is activated to drive the connecting frame 22 and the extrusion plate 23 to descend and press the degradation masterbatches on the surface of the two support platforms 32. By comparing the test results of masterbatches with different degradation times, it is possible to quickly determine whether the degradation masterbatches have met the qualified standards, determine the optimal degradation time, improve the testing efficiency and the accuracy of the results, and facilitate operators to understand the performance of the degradation masterbatches in a timely manner.

[0030] After pressing, the degradation quality of the masterbatch is judged by its brittleness, elasticity, and compressive strength.

[0031] The fixed base 31 provides support for the support platform 32, keeping it parallel in the non-flipped state. The spring 33 provides a reset function for the support platform 32. When the rack 42 is raised and meshes with the gear 43 until it disengages, the support platform 32 will reset under the action of the spring 33 and return to the parallel state because the gear 43 loses its limit.

[0032] The flipping assembly 4 includes a sliding frame 41 fixedly connected to the rear end of the left extrusion plate 23. The outer surface of the sliding frame 41 is slidably connected to the fixed platform 1. A rack 42 is fixedly connected to the outer surface of the sliding frame 41. A gear 43 is meshed with the outer surface of the rack 42. The rear end of the gear 43 is rotatably connected to the fixed platform 1.

[0033] A one-way rotating shaft 44 is rotatably connected to the inner surface of gear 43, and a rotating shaft 45 is fixedly connected to the inner surface of the one-way rotating shaft 44. The outer surface of the rotating shaft 45 is fixedly connected to the support platform 32, and the front end of the rotating shaft 45 is rotatably connected to the fixed platform 1.

[0034] Furthermore, the one-way rotating shaft 44 mentioned above can only rotate counterclockwise in one direction. That is, when the sliding frame 41 follows the extrusion plate 23 down, the gear 43 rotates, while the one-way rotating shaft 44 remains stationary. However, when the sliding frame 41 follows the extrusion plate 23 up, the one-way rotating shaft 44 will rotate together with the gear 43.

[0035] After the extrusion plate 23 has finished testing the degradation masterbatch, the extrusion plate 23 can be controlled to rise, causing the rotating shaft 45 to rotate counterclockwise, further causing the entire support platform 32 to flip to one side, so that the degradation masterbatch tested on the surface of the support platform 32 can slide directly into the collection box 47 through the guide plate 46.

[0036] It should be noted that when the extrusion plate 23 just begins to rise, the support platform 32 will not rotate because the rack 42 and gear 43 have not yet started to mesh. Only when the extrusion plate 23 rises to a certain position and the rack 42 and gear 43 mesh, will the support platform 32 rotate.

[0037] The process avoids the tedious manual unloading, reduces the contact between operators and the degradation masterbatch, lowers labor intensity, and effectively prevents unnecessary damage or contamination to the degradation masterbatch during unloading, ensuring the accuracy and standardization of testing.

[0038] The cleaning component 5 includes sliding grooves 51 on the front and rear sides of the upper end of the support platform 32. The inner surfaces of the two sliding grooves 51 are slidably connected to a sliding seat 52, and the outer surface of the sliding seat 52 is fixedly connected to a push plate 53.

[0039] The bottom end of the push plate 53 is slidably connected to the inner wall of the support platform 32, and the upper end of the sliding seat 52 is fixedly connected to the handle 54.

[0040] Furthermore, pulling the handle 54 can move the push plate 53 to scrape away the residual degradation masterbatch adhering to the surface of the support platform 32, ensuring that the support platform 32 is clean and tidy for the next use, avoiding interference from residual degradation masterbatch to subsequent tests, ensuring the reliability of test results, and extending the service life of the device.

[0041] Working principle: Two types of degradation masterbatches with different degradation times are placed on the surface of the support platform 32. The hydraulic device 21 is activated to drive the connecting frame 22 and the extrusion plate 23 to descend, pressing the degradation masterbatches on the surfaces of the two support platforms 32. The test results of masterbatches with different degradation times are compared to quickly determine whether the degradation masterbatches meet the qualified standards. After the extrusion plate 23 has finished testing the degradation masterbatches, the extrusion plate 23 can be controlled to rise. When the extrusion plate 23 just begins to rise, the support platform 32 will not flip because the rack 42 and gear 43 have not yet started to mesh. Only when the extrusion plate 23 rises to a certain position and the rack 42 and gear 43 mesh, will the support platform 32 flip, allowing the degradation masterbatches on its surface to slide directly into the collection box 47 through the guide plate 46.

[0042] When the rack 42 rises to the top and disengages from the gear 43, the entire support platform 32 will reset under the action of the spring 33 and return to a parallel state. At this time, the handle 54 can be manually pulled to move the push plate 53 to scrape away the residual degradation masterbatch adhering to the surface of the support platform 32, ensuring that the support platform 32 is clean and tidy for the next use.

[0043] It should be noted that the specific installation method, circuit connection method and control method of the hydraulic device 21 used in this invention are all conventional designs, and will not be described in detail in this invention.
