Description

Technical Field

[0001] This utility model belongs to the field of heat resistance testing technology, specifically relating to a device for testing the heat resistance of biodegradable modified materials. Background Technology

[0002] With the increasing global awareness of environmental protection and the advancement of sustainable development strategies, biodegradable materials, as an environmentally friendly material, have received widespread attention. Biodegradable materials can be decomposed into harmless substances such as water and carbon dioxide by microorganisms in the natural environment, thereby effectively reducing plastic pollution. However, biodegradable materials still face some challenges in practical applications, among which insufficient heat resistance is one of the key factors restricting their widespread application.

[0003] The existing technology has the following problems: the position of the heating mechanism of the existing testing device on the market is generally fixed, which makes it inconvenient to adjust the distance between it and the biodegradable modified material. When the distance is large, the heating effect on the surface of the biodegradable modified material is poor, resulting in low heating efficiency of the biodegradable modified material. Utility Model Content

[0004] The purpose of this invention is to provide a device for testing the heat resistance of biodegradable modified materials, in order to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a heat resistance testing device for biodegradable modified materials, including a base, a box body fixedly installed on the top of the base, a controller assembly fixedly installed on one side of the top of the base, a cylinder fixedly installed on the top of the box body, and a support plate fixedly connected to the output end of the cylinder.

[0006] A mounting plate is fixedly connected to the bottom of the support plate. Multiple heating lamps are linearly arranged on the bottom of the mounting plate. An infrared temperature sensor is fixedly installed near the center of the bottom of the mounting plate. A transparent window is provided on the front of the housing. A handle is fixedly installed on one side of the front of the transparent window.

[0007] The present invention further explains that a limit rod is provided at each of the four corners of the support plate, and a rectangular block is provided on the outer wall of the limit rod near the middle. A buffer spring is fixedly connected to the bottom of the rectangular block, and the bottom of the buffer spring is fixedly connected to the inside of the box.

[0008] Using the above technical solution, the support plate moves along the limiting rod, and the buffer spring connected to the rectangular block on the outer wall of the limiting rod plays a buffering role during the movement, reducing the impact of vibration on the test and ensuring the stable operation of the device.

[0009] The present invention further describes that a rotating rod is provided inside the base, a large gear is fixedly connected to the outer wall of the rotating rod near the middle, a small gear is meshed with one side of the large gear, a motor is fixedly installed inside the base, and the output end of the motor is fixedly connected to the bottom of the small gear, and a bearing is provided at the bottom of the rotating rod.

[0010] Using the above technical solution, the motor inside the base starts, driving the small gear to rotate. The small gear meshes with the large gear, thereby driving the rotating rod to rotate. The placement plate connected to the top of the rotating rod rotates accordingly, so that the sample is heated evenly during the heating process.

[0011] The present invention further describes that a storage tray is fixedly connected to the top of the rotating rod, a fixing plate is provided inside the storage tray, a lifting handle is fixedly connected to both sides of the fixing plate, and multiple placement trays are provided inside the fixing plate.

[0015] The present invention further describes that a limiting annular groove is provided inside the box body, and a limiting movable rod is movably connected inside the limiting annular groove, and the top of the limiting movable rod is fixedly connected to the bottom of the storage tray.

[0016] Using the above technical solution, the limiting rod at the bottom of the storage tray moves within the limiting ring groove inside the box, ensuring that the storage tray rotates smoothly.

[0017] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0018] This invention provides a device for testing the heat resistance of biodegradable modified materials. A controller assembly starts the cylinder, which in turn moves the support plate vertically downwards. This lowers the mounting plate and its bottom heating lamps and infrared temperature sensor to a suitable position, allowing the spacing between the heating lamps and the biodegradable modified material to be adjusted according to the material's height. This avoids the problem of heating lamps taking too long to heat smaller biodegradable modified material surfaces, improving the efficiency of surface heating. Simultaneously, multiple heating lamps at the bottom of the mounting plate emit heat to heat the sample, and the infrared temperature sensor monitors the sample temperature in real time, transmitting the temperature data to the controller assembly, thus meeting the user's operational needs.

[0019] This invention provides a device for testing the heat resistance of biodegradable modified materials. A support plate moves along a limiting rod, and a buffer spring connected to a rectangular block on the outer wall of the limiting rod buffers vibrations during movement, reducing the impact of vibrations on the test and ensuring stable operation. An internal motor drives a small gear, which meshes with a large gear, driving a rotating rod. The placement tray connected to the top of the rotating rod rotates accordingly, ensuring uniform heating of the sample during the heating process and improving the comprehensiveness and accuracy of the test. The placement tray includes a liftable fixing plate and multiple placement trays for convenient sample placement and replacement. The cooperation between the limiting ring groove and the limiting movable rod ensures smooth rotation of the placement tray, further enhancing the flexibility of the test and meeting the user's needs.

[0027] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-5 The present invention provides a technical solution: a device for testing the heat resistance of biodegradable modified materials, including a base 1, a box 2 fixedly installed on the top of the base 1, a controller assembly 3 fixedly installed on one side of the top of the base 1, a cylinder 4 fixedly installed on the top of the box 2, and a support plate 5 fixedly connected to the output end of the cylinder 4.

[0029] A mounting plate 6 is fixedly connected to the bottom of the support plate 5. Multiple heating lamps 7 are linearly arranged at the bottom of the mounting plate 6. An infrared temperature sensor 8 is fixedly installed near the center of the bottom of the mounting plate 6. A transparent window 9 is provided on the front of the housing 2. A handle 10 is fixedly installed on one side of the front of the transparent window 9.

[0030] In this embodiment, the controller assembly 3 starts the device, and the cylinder 4 begins to operate. Its output end drives the support plate 5 to move vertically downward, thereby lowering the mounting plate 6 and the heating lamps 7 and infrared temperature sensors 8 at its bottom to a suitable position. This allows the spacing between the heating lamps 7 and the biodegradable modified material to be adjusted according to the height of the biodegradable modified material, thus avoiding the phenomenon that the heating lamps 7 need to spend a lot of time heating the surface of the smaller biodegradable modified material, improving the efficiency of heating the surface of the biodegradable modified material. At the same time, the multiple heating lamps 7 at the bottom of the mounting plate 6 emit heat to heat the sample, and the infrared temperature sensor 8 monitors the sample temperature in real time and transmits the temperature data to the controller assembly 3. In addition, the design of the transparent window 9 on the front of the box 1 with the handle 10 makes it convenient for the operator to open the box 1 at any time to place and take out samples, and also allows for direct observation of the sample status during the test without frequent opening of the box to disturb the test environment. This greatly improves the convenience of the test operation and the control of the test process, thereby improving the accuracy and reliability of the test results.

[0031] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, a limiting rod 11 is provided at each of the four corners of the support plate 5. A rectangular block 12 is provided near the center of the outer wall of the limiting rod 11. A buffer spring 13 is fixedly connected to the bottom of the rectangular block 12, and the bottom of the buffer spring 13 is fixedly connected to the inside of the box 2. A rotating rod 14 is provided inside the base 1. A large gear 15 is fixedly connected near the center of the outer wall of the rotating rod 14. A small gear 16 is meshed with one side of the large gear 15. A motor 17 is fixedly installed inside the base 1, and the output end of the motor 17 is fixedly connected to the bottom of the small gear 16. A bearing 18 is provided at the bottom of the rotating rod 14. A storage tray 19 is fixedly connected to the top of the rotating rod 14. A fixing plate 20 is provided inside the storage tray 19. A lifting handle 21 is fixedly connected to both sides of the fixing plate 20. Multiple placement trays 22 are provided inside the fixing plate 20.

[0032] In this embodiment, the support plate 5 moves along the limiting rod 11. The buffer spring 13 connected to the rectangular block 12 on the outer wall of the limiting rod 11 plays a buffering role during the movement, reducing the impact of vibration on the test and ensuring stable operation of the device. The motor 17 inside the base 1 starts, driving the pinion 16 to rotate. The pinion 16 meshes with the large gear 15, thereby driving the rotating rod 14 to rotate. The placement tray 19 connected to the top of the rotating rod 14 rotates accordingly, so that the sample is heated evenly during the heating process. The operator can remove the fixing plate 20 along with the placement tray 22 from the placement tray 19 by pulling the handle 21, and then perform subsequent analysis and processing on the sample.

[0033] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides a technical solution: preferably, the bottom of the base 1 is fixedly installed with a support leg 23, and the number of support legs 23 is multiple and the multiple support legs 23 are distributed at the four corners of the bottom of the base 1. The inside of the box 2 is provided with a limiting ring groove 24, and the inside of the limiting ring groove 24 is movably connected to a limiting moving rod 25, and the top of the limiting moving rod 25 is fixedly connected to the bottom of the storage tray 19.

[0034] In this embodiment, the four corner supports 23 of the base 1 provide stable support for the entire device, ensuring that the testing process is safe and reliable. The limiting rod 25 at the bottom of the tray 19 moves in the limiting ring groove 24 inside the box 2, ensuring that the tray 19 rotates smoothly.

[0035] like Figure 1-5As shown, when the user needs to use it, the device is activated via the controller assembly 3. The cylinder 4 starts operating, and its output end drives the support plate 5 to move vertically downwards. This causes the mounting plate 6 and the heating lamps 7 and infrared temperature sensors 8 at its bottom to descend to a suitable position. This allows the spacing between the heating lamps 7 and the biodegradable modified material to be adjusted according to the height of the biodegradable modified material. This avoids the phenomenon that the heating lamps 7 need to spend a lot of time heating the surface of the smaller biodegradable modified material, thus improving the efficiency of heating the surface of the biodegradable modified material. At the same time, the multiple heating lamps 7 at the bottom of the mounting plate 6 emit heat to heat the sample. The infrared temperature sensor 8 monitors the sample temperature in real time and transmits the temperature data to the controller assembly 3. The support plate 5 moves along the limit rod 11. The buffer spring 13 connected to the rectangular block 12 on the outer wall of the limit rod 11 plays a buffering role during the movement, reducing the impact of vibration on the test and ensuring the stability of the device. During operation, the motor 17 inside the base 1 starts, driving the small gear 16 to rotate. The small gear 16 meshes with the large gear 15, thereby driving the rotating rod 14 to rotate. The placement tray 19 connected to the top of the rotating rod 14 rotates accordingly, achieving uniform heating of the sample during the heating process and improving the comprehensiveness and accuracy of the test. The placement tray 19 is equipped with a liftable fixing plate 20 and multiple placement trays 22, which facilitates the placement and replacement of samples. The cooperation between the limiting ring groove 24 and the limiting movable rod 25 ensures that the placement tray 19 rotates smoothly, further enhancing the flexibility of the test. The operator can directly observe the changes in the state of the sample during the heating process, such as deformation and melting, through the transparent window 9 on the front of the chamber 2. After the test is completed, the cylinder 4 drives the support plate 5 to rise, and the heating lamp 7 and infrared temperature sensor 8 move away from the sample. The operator can then remove the fixing plate 20 along with the placement trays 22 from the placement tray 19 by pulling the handle 21 for subsequent analysis and processing of the sample.
