[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1

[0037] See also Figure 1 - Fig.11 As shown, the aging resistance test equipment based on the pesticide packaging barrel includes an equipment body 1, an ultraviolet lamp 62 is fixedly connected inside the equipment body 1, and a rotating mechanism is arranged inside the equipment body 1.

The rotating mechanism includes three sets of sleeve rods 24 and support rods 27. The three sets of sleeve rods 24 are all sleeved with a third belt 63. The sleeve rods 24 and the support rods 27 are fixedly connected to a rotating block 28 on the side away from the packaging barrel body 20. The rotating block 28 is T-shaped and is rotatably connected to the inner wall of the equipment body 1. The right side of the support rod 27 Abutting against the outer side of the packaging barrel body 20, the inner wall of the packaging barrel body 20 abuts against the movable rod 21, the interior of the movable rod 21 is hollowed out, a magnet 25 is fixedly connected to the movable rod 21, the movable rod 21 is inserted into the interior of the packaging barrel body 20, the right side of the movable rod 21 is inserted into the sleeve rod 24, a first spring 26 is fixedly connected to the inner wall of the sleeve rod 24, the left side of the first spring 26 is fixedly connected to the inner wall of the movable rod 21, a first belt 31 is sleeved on the right side of the front sleeve rod 24, the bottom end of the first belt 31 is sleeved on the rotating wheel 30, and a speed reduction mechanism is provided on the rotating wheel 30, and the speed reduction mechanism is used to adjust the rotation speed of the rotating mechanism;

[0038] Through the structural design of the rotating mechanism, the function of continuously flipping the packaging barrel main body 20 during the test is realized, so that the ultraviolet lamp can evenly irradiate the surface of the packaging barrel main body 20, and improve the uniformity of the test. Since the packaging barrel main body 20 will be exposed to ultraviolet rays from different directions during actual use, this actual situation can be simulated by rotating the packaging barrel main body 20, so that the test result is closer to the actual situation. In addition, rotating the packaging barrel main body 20 can also reduce the test error caused by improper placement of the packaging barrel main body 20. When working, first push the movable rod 21 to allow the movable rod 21 to be stored in the sleeve rod 24, the first spring 26 fixed on the movable rod 21 will be compressed, and the distance between the movable rod 21 and the support rod 27 will gradually increase until the packaging barrel main body 20 can be smoothly placed between the movable rod 21 and the support rod 27. At this time, after ensuring that the bottle mouth of the packaging barrel main body 20 is roughly aligned with the movable rod 21, the movable rod 21 is no longer pushed, and the first spring 26 will push the movable rod 21 to be inserted into the interior of the packaging barrel main body 20. A magnet 25 is fixed on 21. When the movable rod 21 abuts against the inner wall of the packaging barrel body 20, the packaging barrel body 20 is fixed by the magnet 25 to the support rod 27. A group of magnets 25 can also be fixed on the support rod 27 to improve the fixing effect of the packaging barrel body 20. Since the sleeve rod 24 and the rotating block 28 fixed on the support rod 27 rotate on the inner wall of the equipment body 1, the sleeve rod 24 can drive the support rod 27 to rotate, thereby driving the packaging barrel body 20 to rotate during the test. The front sleeve rod 24 is sleeved with a first belt 31, the bottom end of the first belt 31 is sleeved on the rotating wheel 30 and driven by the rotating wheel 30, and the three groups of sleeve rods 24 are all sleeved with a third belt 63, so as to transmit the rotation of the front sleeve rod 24 to the remaining two groups of sleeve rods 24, so that the three groups of sleeve rods 24 can rotate synchronously, wherein the sleeve rods 24 and the support rods 27 can be provided in multiple groups according to actual needs, so as to test multiple groups of packaging barrel bodies 20 at the same time, and the distance between two adjacent groups of sleeve rods 24 should be greater than the packaging barrel body 20, so as to fix larger-sized pesticide packaging barrels.

[0039] Furthermore, the reduction mechanism includes a reduction motor 32, the output shaft of the reduction motor 32 is fixedly connected to the rotating wheel 30, the bottom end of the reduction motor 32 is fixedly connected to the inner wall of the device body 1, the input shaft of the reduction motor 32 is fixedly connected to the first gear 33, the bottom end of the first gear 33 is meshed with the connecting gear 34, the connecting gear 34 is rotatably connected to the inner wall of the device body 1, the connecting gear 34 is meshed with the gear ring 36, the left and right sides of the gear ring 36 are provided with a slide groove 41, the inside of the slide groove 41 is slidably connected with a slider 42, and the slider 42 is fixedly connected The support frame 37 is connected to the inner wall of the device body 1, the bottom end of the gear ring 36 is meshed with the second gear 38, the second gear 38 is fixedly connected to the rotating shaft 40, the rotating shaft 40 is rotatably connected to the inner wall of the device body 1, the rotating shaft 40 is fixedly connected to the first rotating disk 35, the first rotating disk 35 is rotatably connected with a connecting rod 46, the bottom end of the connecting rod 46 is rotatably connected to the second rotating disk 47, the second rotating disk 47 is fixedly connected to the rotating shaft of the driven gear 48, and the driven gear 48 is rotatably connected to the inside of the gear pump 49;

[0040] Through the structural design of the speed reduction mechanism, the rotation of the driven gear 48 inside the gear pump 49 can be transmitted, and the rotation speed of the driven gear 48 can be adjusted to ensure that the rotation speed of the sleeve rod 24 will not be too fast, so that the packaging barrel body 20 can rotate at a slower speed, so that all parts of the surface of the packaging barrel body 20 can be irradiated with ultraviolet rays more evenly, which helps to simulate the actual use of the packaging barrel body 20 to improve the accuracy and reliability of the aging test. When working, when the driven gear 48 inside the gear pump 49 rotates, the driven gear 48 drives the second rotating disk 47 to rotate, and the second rotating disk 47 is connected to the first rotating disk 3 through the connecting rod 46. 5 is connected together and drives the first rotating disk 35 to rotate. The first rotating disk 35 and the second gear 38 are both fixed on the rotating shaft 40. The rotation of the second gear 38 will drive the ring gear 36 to rotate between the two sets of support frames 37. A slider 42 is fixed on the support frame 37. The slider 42 slides in the slide groove 41 to provide support for the ring gear 36. The top of the ring gear 36 is meshed with the connecting gear 34. The connecting gear 34 is meshed with the ring gear 36 and also keeps meshing with the first gear 33. The first gear 33 is connected to the input shaft of the reduction motor 32.

The device body 1 is provided with ventilation slots 45 at positions corresponding to the fan blades 44, and the ventilation slots 45 run through the left and right sides of the device body 1.

[0042] The structural design of the fan blade 44 is to simulate the air flow in the natural environment, so that the inside of the test box can be closer to the real environment, and the faster rotation speed of the fan blade 44 can accelerate the aging process of the packaging barrel body 20 to reduce the test time. At the same time, the fan blade 44 is driven by a deceleration mechanism to avoid the need to set up an additional power source to drive the fan blade 44, which can reduce energy waste and reduce the dependence of the device body 1 on the ventilation equipment. When working, two sets of mounting rings 39 are fixed on the rotating shaft 40. The mounting ring 39 is used to limit the second belt 43 to ensure that the position of the second belt 43 on the rotating shaft 40 will not change. The rotation of the rotating shaft 40 will be transmitted to the fan blade 44 through the second belt 43, thereby driving the fan blade 44 to rotate. The fan blade 44 can accelerate the air flow inside the device body 1, making the internal temperature of the device body 1 more uniform, thereby ensuring that each packaging barrel body 20 can be aged under the same temperature conditions, and there is no need to set up an additional power source to drive the fan blade 44.

The spray pipe 53 is supported and fixed by three sets of retaining frames 54. The collection box 52 can collect the spray water. Through the design of the spray pipe 53, the aging of the packaging barrel main body 20 under the erosion of rain in the outdoor environment can be simulated, so as to more comprehensively simulate the environmental changes experienced by the packaging barrel main body 20 in actual use, and observe the aging of the packaging barrel main body 20 in a humid environment.

[0045] Furthermore, two sets of drainage holes 55 are provided on the collection box 52. The drainage holes 55 penetrate the rear end of the device body 1. The drainage holes 55 are located near the top of the collection box 52.
