Description

Technical Field

[0001] This application relates to the technical field of plastic bucket aging, and specifically provides an aging test chamber for plastic buckets. Background Art

[0002] Plastic bucket aging refers to the process in which plastic buckets, during use or storage, gradually degrade in their physical and chemical properties due to long-term exposure to environmental factors such as light, temperature, oxygen, and chemical substances, eventually showing phenomena such as embrittlement, discoloration, cracking, and strength decline. In order to ensure the quality of plastic buckets, after new plastic buckets are produced, samples need to be taken for plastic bucket aging tests, mainly to evaluate the stability and durability of plastic buckets, and secondly, to predict the service life of plastic buckets. An aging test chamber for plastic buckets is a device specifically used to simulate and accelerate the aging process of plastic buckets.

[0003] For example, the patent with the authorization announcement number CN208155820U discloses a plastic aging test chamber, including a test chamber, a first linkage rod, a second linkage rod, a third linkage rod, a fourth linkage rod, a driving rod, a turntable and other structures, which controls the rotation of the fixed frame to make it evenly exposed to xenon light, avoiding the influence of uneven irradiation on the test structure, and at the same time setting it on the outer wall of the test chamber of the test chamber, so that the driving motor can dissipate heat naturally during operation.

[0004] Although the above device realizes the aging test of plastic buckets, in actual use, due to the influence of region, weather or usage method, plastic buckets usually need to be transported or stored. However, during transportation, plastic buckets are usually outdoors. In summer when the temperature is high, plastic buckets during transportation often experience long-term high-temperature exposure. Secondly, if the plastic bucket contains materials such as food, at this time the plastic bucket needs to be refrigerated in a low-temperature environment to avoid the deterioration and damage of the materials inside the bucket. Therefore, plastic buckets are usually transported in a high-temperature environment, and after reaching the destination, the plastic buckets will be refrigerated in a low-temperature environment. The temperature difference between the two environments is large. If the plastic buckets in the high-temperature transportation and refrigerated temporary storage states cannot be tested, it may affect the accuracy of the plastic bucket aging test. Therefore, it is necessary to provide an aging test chamber for plastic buckets to solve the above problems.

[0005] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute prior art. Summary of the Invention

Specific embodiments

[0028] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe this application in detail with reference to the drawings and in combination with the embodiments.

[0029] To enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0030] Embodiment 1: This embodiment mainly introduces the basic structure and working principle of a plastic bucket aging test chamber. Specifically:

[0031] As Figures 1-3 shown, this application provides a plastic bucket aging test chamber, including a box body 1, which is the main part of the plastic bucket aging test chamber. A box door 2 is hingedly installed on one side of the box body 1. The staff controls the flipping of the box door 2 to open or close the box body 1, mainly for facilitating the plastic bucket aging test.

[0032] A test component 3 is installed in the box body 1. The test component 3 is mainly used to conduct an aging test on the plastic bucket. The test component 3 includes a bottom frame 32 fixedly installed in the box body 1, which is mainly used for support. A support plate 33 is placed on the top of the bottom frame 32, and a sample bucket 10 is placed on the support plate 33. The sample bucket 10 is a sampling piece of the batch of plastic buckets that have been produced.

[0033] A xenon lamp (not shown in the figure) is also fixedly installed at the top inside the box body 1. When the xenon lamp is turned on, it is suitable for emitting xenon light to simulate sunlight irradiating the sample bucket 10, thereby conducting the aging test of the plastic bucket.

[0034] In this embodiment, in order to enable the sample bucket 10 to be evenly irradiated by the xenon light, a motor (not shown in the figure) is fixedly installed at the bottom of the box body 1. The output end of the motor is fixedly connected to the bottom of the support plate 33. When the motor starts, it drives the support plate 33 to rotate, so that the sample bucket 10 located on the support plate 33 rotates synchronously. Thus, the xenon light will continuously irradiate the rotating sample bucket 10, making the irradiated area of the sample bucket 10 more uniform.

[0035] By irradiating the sample bucket 10 with xenon light for a long time, the aging of the sample bucket 10 is accelerated, thereby completing the aging test of the plastic bucket. In order to further make the plastic bucket aging test more in line with the actual use scenario, continue to refer to Figure 3, at least two groups of temperature control pipes 31 are fixedly installed on both sides inside the box body 1. A plurality of groups of exhaust holes (not marked in the figure) are formed on the surface of the temperature control pipes 31. A high-temperature intake pipe and a low-temperature intake pipe are respectively and fixedly installed inside the box body 1. One ends of the high-temperature intake pipe and the low-temperature intake pipe are both connected to the temperature control pipes 31, and the other ends are connected to an electric heater and a condenser outside the box body 1. When high-temperature gas or low-temperature gas is introduced into the high-temperature intake pipe and the low-temperature intake pipe, the high-temperature gas and the low-temperature gas will enter the temperature control pipes 31 and be discharged from the exhaust holes, thereby heating or cooling the inside of the box body 1;

[0036] During the day, the staff can turn on the xenon lamp and then turn on the electric heater, and introduce hot air flow into the high-temperature intake pipe. The hot air flow then enters the box body 1 through the exhaust holes on the temperature control pipes 31, realizing the temperature rise inside the box body 1. At this time, the sample bucket 10 is affected by both high temperature and light, so as to simulate the scenario where the plastic bucket is exposed to sunlight outdoors in summer;

[0037] During the night, the staff can turn off the xenon lamp, turn off the electric heater and turn on the condenser at the same time. The cold air blown out by the condenser enters the low-temperature intake pipe, and finally the cold air is discharged through the exhaust holes of the temperature control pipes 31 to cool the inside of the box body 1. It should be noted that the cold air usually reaches sub-zero temperature to be used to simulate the scenario where the plastic bucket is refrigerated in a low-temperature environment;

[0038] When the sample bucket 10 experiences high temperature and low temperature environments, the staff starts the motor to drive the sample bucket 10 to rotate, so that the sample bucket 10 is heated or cooled more evenly. In this way, after the sample bucket 10 is affected by high temperature, light and low temperature environments, its aging process will be accelerated, thus completing the aging test of the plastic bucket, and the aging environment of the sample bucket 10 is more in line with the actual use scenario;

[0039] However, for the convenience of detection, a PLC control system is arranged inside the box body 1 to facilitate the alternating opening and closing of each electrical component inside the box body 1.

[0040] Embodiment 2: The above embodiment realizes the aging test of the plastic bucket through the simulation of the environment of light and high and low temperatures. However, when the plastic buckets are transported, collisions will inevitably occur between the buckets. When collisions occur between the plastic buckets, this physical effect will accelerate the aging process of the plastic buckets, especially when the road section is bumpy, the collisions between the plastic buckets are more intense;

[0041] Furthermore, it is necessary to simulate the scenario where the plastic buckets collide with each other to obtain more accurate aging test results. In this embodiment, the movement trajectory of the plastic buckets is improved. Specifically, as Figures 3-5As shown, a first mounting position 331 is fixedly installed on one side of the support disk 33. The top of the first mounting position 331 protrudes from the top of the support disk 33, and a circular mounting groove is formed inside. In this embodiment, the inner diameter of the circular mounting groove is slightly larger than the outer diameter of the sample bucket 10. The first mounting position 331 is mainly used to limit the sample bucket 10. After the sample bucket 10 is placed in the first mounting position 331, even if an external force acts, the sample bucket 10 will not move;

[0042] A limiting groove 332 is formed in the support disk 33, and a mounting disk 333 is slidably installed in the limiting groove 332. Another group of sample buckets 10 are suitable to be placed on the mounting disk 333. In this embodiment, the mounting disk 333 can be a mechanical chuck. After the sample bucket 10 is placed on the mounting disk 333, the mounting disk 333 fixes the bottom of the sample bucket 10 through electric control clamping to prevent the sample bucket 10 from detaching from the mounting disk 333;

[0043] At least two groups of return springs 334 are fixedly installed on one side of the mounting disk 333, and the other side of the return springs 334 is fixedly connected to the inner wall of the limiting groove 332. In the initial state, as Figure 3 shown, the mounting disk 333 is located on the side away from the first mounting position 331. If an external force acts on the mounting disk 333 at this time, the mounting disk 333 is suitable to slide towards the first mounting position 331, and at the same time the return springs 334 are compressed. After the external force is removed, the mounting disk 333 automatically resets under the elastic force of the return springs 334;

[0044] In order to facilitate the mutual contact between the sample buckets 10, an opening is provided on one side of the first mounting position 331 close to the mounting disk 333. When the mounting disk 333 moves towards the first mounting position 331, the two sample buckets 10 are suitable to contact each other. If the displacement speed is relatively fast, the sample buckets 10 will collide with each other;

[0045] Furthermore, in order to simulate the scenario of the plastic buckets bumping and colliding with each other during transportation, the difference between this embodiment and the first embodiment is that in the first embodiment, the bottom of the support disk 33 is fixedly connected to the motor, and the motor drives it to rotate. In this embodiment, the structure of the bottom of the support disk 33 is improved. As Figure 3 、 Figures 5-8 shown, a guiding groove (not shown in the figure) is formed in the middle of the bottom surface of the support disk 33, and a hinge member (not marked in the figure) is installed in the guiding groove. The hinge member is mainly composed of a fixed end and a hinged end. The hinged end is hingedly installed on the top of the fixed end, and the top of the hinged end is fixedly connected to the guiding groove. It should be noted that Figure 3 、 Figure 6For reference, the lengths before and after the hinge end are the same as the lengths before and after the guide groove. When the weights at both ends of the support disk 33 are different, due to the hinge, the support disk 33 is adapted to tilt towards the heavier side. In this application, due to the limitation of the guide groove on the hinge end, the support disk 33 can only tilt left and right towards the first mounting position 331 or the mounting disk 333 and cannot tilt in other directions. Its principle is the same as that of the existing balance structure;

[0046] Side plates 34 are fixedly installed on both sides of the chassis 32. The distance between the two side plates 34 is slightly larger than the diameter of the support disk 33. A fence 35 is fixedly installed at the top of the side plates 34. This fence 35 is mainly used to prevent the sample bucket 10 from tipping over. The inner diameter of this fence 35 is larger than the distance between the side plates 34 and larger than the diameter of the support disk 33. As Figure 3 shown in the figure, in the initial state, the outer wall of the support disk 33 is in contact with the surface of the side plates 34. At this time, the side plates 34 limit both sides of the support disk 33, and the support disk 33 cannot tilt and can only maintain a horizontal state. If the support disk 33 is continuously lifted, the support disk 33 rises continuously, and its surface separates from the side plates 34. After separation, the support disk 33 is not restricted by anything. At this time, when the weights of the sample buckets 10 on the support disk 33 are different, the support disk 33 will tilt. Due to the limitation of the fence 35 on the sample bucket 10, after tilting to a certain angle, the support disk 33 cannot continue to tilt, preventing the sample bucket 10 from tipping over completely;

[0047] In this embodiment, in order to make the test results more realistic, usually when starting the test, the staff needs to inject the test solution into the sample bucket 10 and place it on the first mounting position 331. The solution injected into the sample bucket 10 on the first mounting position 331 is more than the solution in the sample bucket 10 placed on the mounting disk 333. For the convenience of explanation, the sample bucket 10 on the first mounting position 331 is defined as the first bucket, and the sample bucket 10 on the mounting disk 333 is defined as the second bucket. The weight of the first bucket is usually greater than that of the second bucket. When there is no external force restriction on the support disk 33, the support disk 33 will tilt towards the direction of the first bucket, and the second bucket will move towards the position of the first bucket;

[0048] Continue to refer to Figures 5-8 , an adjusting sleeve 5 is fixedly installed at the bottom of the hinge. The inside of the adjusting sleeve 5 is hollow and provided with a downward notch. A cylinder 4 is fixedly installed inside the box body 1. The output end of the cylinder 4 protrudes from the bottom inside the box body 1 and is fixedly installed with a pushing member 7. The outer diameter of the pushing member 7 is adapted to the inner diameter of the adjusting sleeve 5. A holding member 8 is arranged on one side of the pushing member 7. The holding member 8 and the pushing member 7 are integrally arranged. It should be noted that the end of the holding member 8 away from the pushing member 7 is made of a flexible material;

[0049] Meanwhile, an adjustment groove 6 for cooperating with the abutting member 8 is formed in the adjustment sleeve 5. The adjustment groove 6 includes a first channel 61 formed in the adjustment sleeve 5. The first channel 61 is a vertical channel. In the initial state, the abutting member 8 abuts against the bottom of the first channel 61, and at this time, the abutting member 8 is already in a compressed state. A second channel 62 that rotates downward is provided at the end of the first channel 61. The end of the second channel 62 is located at a position where the first channel 61 rotates 180 degrees around the center point of the adjustment sleeve 5. And the bottom height of the second channel 62 is lower than the bottom height of the first channel 61 and forms a first step. When the abutting member 8 enters the second channel 62 from the first channel 61, it cannot return from the second channel 62 to the first channel 61. The position where the first channel 61 communicates with the second channel 62 forms a first stagnation point 65;

[0050] A third channel 63 that is vertically upward is provided at the end of the second channel 62. The bottom height of the third channel 63 is lower than the bottom height of the second channel 62 and forms a second step. Thus, when the abutting member 8 enters the third channel 63 from the second channel 62, it cannot return from the third channel 63 to the second channel 62. A second stagnation point 66 is provided at the communicating part of the second channel 62 and the third channel 63;

[0051] In order to facilitate the abutting member 8 to stay at different positions, a turntable 71 is rotatably installed on the top of the pushing member 7, and a force-relieving spring 9 is fixedly installed on the top of the turntable 71. The other end of the force-relieving spring 9 is fixedly connected to the top inside the adjustment sleeve 5;

[0052] It should be noted that due to the certain weight of the support disc 33 itself, in the initial state, the bottom of the hinge member is placed on the chassis 32, and the hinge member and the support disc 33 can only move upward;

[0053] When conducting the aging test of the plastic bucket, the staff pre-loads the test solution into the sample bucket 10, and then places the sample bucket 10 on the first installation position 331 and the installation disc 333 respectively. Then the staff controls the condenser to start, and the cold air flows out from the exhaust hole at the temperature control pipe 31 to cool the inside of the box body 1, thereby simulating the state of the plastic bucket under low-temperature refrigeration;

[0054] After refrigeration for a certain period of time, the staff controls the condenser to close and simultaneously turns on the electric heater and the xenon lamp. After the temperature inside the box 1 changes from low to high and stabilizes, the staff starts the cylinder 4. The output end of the cylinder 4 drives the pushing member 7 to move upward. The upward movement of the pushing member 7 drives the abutting member 8 to move upward synchronously. The abutting member 8 slides in the first channel 61. With the continuous action of the cylinder 4, the abutting member 8 slides to the position of the first stationary point 65. During the sliding process of the abutting member 8, the force-relieving spring 9 is compressed. When the abutting member 8 slides to the position of the first stationary point 65, at this time, the abutting member 8 cannot move upward continuously, but the output end of the cylinder 4 continues to act. At this time, the cylinder 4 will drive the pushing member 7 to drive the adjusting sleeve 5 to move upward. The upward movement of the adjusting sleeve 5 drives the abutting member 8 to move upward, thereby driving the support plate 33 and the sample bucket 10 to move upward synchronously. Finally, the support plate 33 moves to the top of the side plate 34 and does not separate from the side plate 34;

[0055] Subsequently, the staff controls the cylinder 4 to close, and the output end of the cylinder 4 retracts. The adjusting sleeve 5 and the abutting member 8 retract synchronously. When the hinge member moves downward and returns to the chassis 32, the adjusting sleeve 5 cannot move downward continuously. At this time, the output end of the cylinder 4 has not returned to the initial position, and the output end of the cylinder 4 continues to retract. The abutting member 8 continues to move downward. Due to the limitation of the first step, the abutting member 8 enters the second channel 62 and slides. Since the second channel 62 is a channel that rotates downward, and the pushing member 7 cannot rotate, when the abutting member 8 slides in the second channel 62, the adjusting sleeve 5 will rotate adaptively. The rotation of the adjusting sleeve 5 drives the hinge member and the support plate 33 to rotate synchronously, so that the sample bucket 10 will rotate synchronously. Finally, the abutting member 8 reaches the position of the second stationary point 66 driven by the cylinder 4, and at this time, the cylinder 4 returns to the initial state;

[0056] During this movement process, the opening and closing of the cylinder 4 drive the sample bucket 10 to move upward and then downward and rotate. At the same time, the inside of the box 1 is in a high-temperature state, simulating the situation that during the high-temperature transportation of a plastic bucket, the plastic bucket will have changes in the horizontal height position and rotate. Thus, it simulates the scenario where the plastic bucket moves up and down and turns after the car goes uphill and then downhill during transportation, and the plastic bucket bumps during transportation;

[0057] Continue to refer to Figures 7-8, a fourth channel 64 rotating downward is provided at the end of the third channel 63, the end of the fourth channel 64 is communicated with the first channel 61, the groove bottom height of the fourth channel 64 is lower than the groove bottom height of the third channel 63 and forms a third step, so that after the abutting member 8 enters the fourth channel 64 from the third channel 63, it cannot return to the third channel 63 from the fourth channel 64, and a transition slope is provided at the end of the fourth channel 64, the highest position of the transition slope is higher than the groove bottom position of the first channel 61 and forms a transition step, so that when the abutting member 8 slides in the first channel 61, it cannot directly enter the fourth channel 64, but the abutting member 8 is suitable for returning to the first channel 61 through the transition slope, and a third stationary point 67 is provided at the position where the third channel 63 communicates with the fourth channel 64, and the horizontal position height of the third stationary point 67 is lower than the horizontal position height of the first stationary point 65;

[0058] When the cylinder 4 is started and closed for the first time, the staff starts the cylinder 4 again, and the output end of the cylinder 4 drives the pushing member 7 to move upward, and the abutting member 8 slides in the third channel 63 and reaches the third stationary point 67. Due to the limitation of the third channel 63, when the abutting member 8 reaches the third stationary point 67, the abutting member 8 cannot continue to move upward, so that when the cylinder 4 continues to push, the adjustment sleeve 5 will move upward synchronously. Compared with the initial start of the cylinder 4, the adjustment sleeve 5 will move upward earlier. When the output end of the cylinder 4 extends to the extreme position, the support plate 33 moves up a longer distance. At this time, the support plate 33 is separated from the side plate 34, and the longer upward distance is the horizontal height difference between the first stationary point 65 and the third stationary point 67.

[0059] When the support plate 33 is separated from the side plate 34, the support plate 33 is not restricted in any way. Since the first barrel is pre-set to be loaded with more detection solution, the second barrel will tilt toward the first barrel and hit the first barrel. However, the return spring 334 will have a certain slowing effect on the displacement speed of the second barrel, but it will not affect the second barrel from finally fitting and hitting the first barrel.

[0060] After the support plate 33 tilts and the two groups of sample barrels 10 collide, the staff controls the cylinder 4 to close, and the cylinder 4 drives the adjustment sleeve 5 to move downward, and the support plate 33 moves downward synchronously. When the support plate 33 moves downward and contacts the side plate 34, since the inner diameter of the side plate 34 is only slightly larger than the diameter of the support plate 33, the spacing between the tilted support plates 33 is larger than its diameter, and the side plate 34 plays an auxiliary correction role for the support plate 33, so that the support plate 33 is restored from the tilted state to the horizontal state;

[0061] When the support plate 33 is restored to the horizontal position, due to the elastic force of the return spring 334, the mounting plate 333 is also restored to the initial state, so that the sample barrel 10 is restored to the initial position;

[0062] After the bottom of the hinge reaches the top of the chassis 32, the output end of the air cylinder 4 continues to retract. The abutting member 8 moves downward from the third stationary point 67 position into the fourth channel 64 and slides. Eventually, the abutting member 8 returns to its initial position in the first channel 61, and the air cylinder 4 also returns to its initial state. When the abutting member 8 slides in the fourth channel 64, since the fourth channel 64 is also inclined downward, the adjusting sleeve 5 will rotate again. The rotation of the adjusting sleeve 5 drives the support disc 33 to rotate synchronously. Eventually, the adjusting sleeve 5 rotates to its initial angular position;

[0063] During this movement of the air cylinder 4, it drives the support disc 33 to move up to a higher horizontal position. The support disc 33 will tilt under the action of the different weights of the hinge and the sample bucket 10, so that the two groups of sample buckets 10 will collide. When the output end of the air cylinder 4 retracts, the side plate 34 plays an auxiliary correction role for the support disc 33. At the same time, the sample bucket 10 also returns to its initial position under the action of the return spring 334. Thus, the scenario of the plastic bucket jolting and colliding during transportation is simulated;

[0064] At the same time, when the air cylinder 4 is started for the second time, the aging state of the plastic bucket during transportation in a high-temperature environment is simulated, and there is also this physical reaction of impact, making the aging test of the plastic bucket more realistic;

[0065] However, it is difficult to make the aging test of the plastic bucket produce a more obvious reaction only through one impact. Therefore, when the inside of the box body 1 is in a high-temperature state, the staff can turn the air cylinder 4 on and off multiple times. The sample bucket 10 will also collide while moving up and down. In this way, the aging test results of the plastic bucket are more accurate;

[0066] After multiple tests, the elasticity of the return spring 334 will always decrease to some extent. Therefore, during the subsequent reset process, the mounting disc 333 may gradually not be able to return to its initial position. After reset, the second bucket will be closer to the first bucket. And in the next impact, the impact force of the second bucket on the first bucket will be smaller. In subsequent tests, the aging of the sample bucket 10 will slow down. The staff can judge the anti-aging quality of the sample bucket 10 based on the service time of the return spring 334 and the number of times the plastic bucket aging test box is used;

[0067] Similarly, the staff can set an electromagnet at a position on the limit groove 332 away from the first installation position 331, and also set an electromagnet at one end of the mounting disk 333 away from the first installation position 331. The two attract each other with opposite polarities. When the electromagnet is powered on, the mounting disk 333 will move to the other end of the limit groove 332 due to the suction of the electromagnet. At this time, the distance between the first barrel and the second barrel is the farthest. When the abutting member 8 slides in the third channel 63, the electromagnet loses power. Then, when the support disk 33 tilts, the second barrel located at a farther distance starts to move and hits the first barrel. In this way, the second barrel generates a stronger impact on the first barrel to accelerate the aging process of the sample barrel 10;

[0068] After the impact ends, the staff controls the electromagnet to be powered on, and the second barrel resets to facilitate the next impact. In the above process, the opening or closing of each electrical component can be sequentially controlled by the PLC control system, eliminating the need for the staff to switch them individually, thus improving work efficiency;

[0069] In summary, by the combined use of the adjustment groove 6 and the abutting member 8, the movement trajectory of the support disk 33 is changed. The support disk 33 will move up to different heights and then move down in sequence, and the support disk 33 rotates during the downward movement. At the same time, during this movement process, it is combined with the temperature conversion of high temperature in the box body 1 to respectively simulate the aging conditions of the plastic barrel in two states of low-temperature refrigeration and high-temperature transportation. And the sample barrel 10 will generate a physical effect of impact due to the tilt of the support disk 33, accelerating the aging process of the sample barrel 10 and simulating the scenario of bumps and impacts during the transportation of the plastic barrel.
