[0021] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] The plastic bucket impact resistance test device according to the embodiments of the present invention will be described below with reference to the drawings.

[0023] As Figures 1-3 shown, the plastic bucket impact resistance test device according to the embodiments of the present invention may include: a barrel body vertical positioning component 1, a first motor 2, a rotating device 4, a water injection device 5, and a collision environment simulation device 6.

[0024] The barrel body vertical positioning component 1 is detachably connected to the target plastic bucket. The barrel body vertical positioning component 1 is used to fix and move the target plastic bucket. The first motor 2 is detachably connected to the barrel cover through the barrel cover suction cup 3. The first motor 2 is arranged on the rotating device 4. The rotating device 4 is used to drive the barrel cover to move or adjust the working position of the barrel body through the barrel cover. The water injection device 5 is arranged above the barrel body vertical positioning component 1. The water injection device 5 is used to inject a target volume of liquid into the barrel body. The collision environment simulation device 6 is arranged below the barrel body vertical positioning component 1. The collision environment simulation device 6 is used to simulate different collision environments of the plastic bucket.

[0025] It should be noted that when the barrel cover is threadedly connected to the barrel body, the first motor 2 can separate the barrel cover from the barrel body by rotating the barrel cover suction cup 3. When the barrel cover is snap-connected to the barrel body, after the barrel cover suction cup 3 adsorbs the barrel cover, the barrel body vertical positioning component 1 vertically moves the barrel body to separate the barrel cover from the barrel body.

[0026] To clearly illustrate the previous embodiment, in an embodiment of the present invention, as Figure 2 and Figure 3As shown in the figure, the rotating device 4 may include: a second motor 41, a connecting block 42, and a third motor 43. Among them, the driving end of the second motor 41 is connected to the first motor 2 through the connecting block 42. The second motor 41 is used to drive the bucket cover suction cup 3 to rotate vertically. The driving end of the third motor 43 is connected to the second motor 41. The third motor 43 is used to drive the bucket cover suction cup 3 to rotate horizontally.

[0027] It can be understood that in this embodiment, the third motor 43 and the second motor 41 described adjust the working position of the bucket cover suction cup 3 on the first motor 2 to move the bucket cover to a position that does not affect the water injection device 5 from injecting water into the bucket body, or rotate the bucket body through the bucket cover (at this time, the bucket body and the bucket cover are connected), and adjust the falling direction of the plastic bucket (for example, bottom down, side down, etc.).

[0028] In an embodiment of the present invention, as Figure 1 , Figure 4 and Figure 5 shown, the collision environment simulation device 6 includes: an installation bin 62, a plurality of environment simulation plates 61, and a plurality of clamping plates 63. Among them, a plurality of card slots 64 are opened on the installation bin 62. The plurality of card slots 64, the plurality of environment simulation plates 61, and the plurality of clamping plates 63 correspond one by one. The clamping plate 63 is arranged on the environment simulation plate 61. The environment simulation plate 61 is detachably connected to the installation bin 62. The clamping plate 63 is clamped with the card slot 64. The plurality of environment simulation plates 61 are used to simulate various collision contact environments required for plastic bucket testing.

[0029] It should be noted that the plurality of environment simulation plates 61 are vertically arranged on the installation bin 62. Different environment simulation plates 61 can simulate different collision contact environments (for example, concrete surface, steel plate surface, wooden surface, asphalt surface, sand or gravel surface, etc.).

[0030] Specifically, place the plastic bucket (the bucket body and the bucket cover are connected) on the bucket body vertical positioning component 1. After the bucket body vertical positioning component 1 fixes the bucket body, it drives the bucket body to move vertically upward until the bucket cover contacts the bucket cover suction cup 3. After the bucket cover suction cup 3 (for example, a vacuum suction cup) adsorbs the bucket cover, the first motor 2 unscrews the bucket cover through the bucket cover suction cup 3. The third motor 43 can drive the first motor 2 to move through the second motor 41. The first motor 2 horizontally moves the bucket cover away from the bucket body through the bucket cover suction cup 3. After the water injection device 5 injects a target volume of liquid (for example, water) into the bucket body, the bucket cover is reconnected to the bucket body.

[0031] The barrel body vertical positioning component 1 is separated from the barrel body. The second motor 41 can drive the barrel cover suction cup 3 to rotate vertically through the first motor 2, and the third motor 43 drives the barrel cover suction cup 3 to rotate horizontally through the second motor 41 to adjust the dropping angle of the plastic barrel. Before starting the dropping test, adjust the working positions of multiple environmental simulation boards 61 according to the test requirements. By sliding the clamping plate 63 in the card slot 64, move the target environmental simulation board 61 (the collision contact environment to be tested) to the uppermost part of the installation bin 62. After the barrel cover suction cup 3 loses the limit on the barrel cover, make the plastic barrel do a free fall motion, and after colliding with the target environmental simulation board 61, check whether the plastic barrel has cracks, leaks or other forms of damage.

[0032] In an embodiment of the present invention, as Figure 1 and Figure 3 shown, the barrel body vertical positioning component 1 may include: a vertical driving device 11, a fourth motor 12, an electric telescopic rod 13 and a barrel body fixing device 14.

The barrel body fixing device 14 includes: a plurality of positioning devices 141 and a load-bearing plate 142. The load-bearing plate 142 is arranged at the driving end of the electric telescopic rod 13, and the plurality of positioning devices 141 are respectively arranged on the load-bearing plate 142.

[0033] The positioning device 141 includes: an electric push rod 1411, a bent rod 1412 and a positioning push plate 1413. Among them, the electric push rod 1411 is arranged at the lower part of the load-bearing plate 142, one end of the bent rod 1412 is connected to the driving end of the electric push rod 1411, and the other end of the bent rod 1412 is connected to the positioning push plate 1413.

[0034] Specifically, the electric push rod 1411 can drive the positioning push plate 1413 to move to a position through the bent rod 1412. The plurality of positioning push plates 1413 clamp and position the barrel body on the load-bearing plate 142 by abutting against the barrel body. The vertical driving device 11 can adjust the position of the electric telescopic rod 13 through the fourth motor 12, and the electric telescopic rod 13 can drive the load-bearing plate 142 to move, achieving the effect of driving the load-bearing plate 142 to move vertically. After the barrel cover suction cup 3 adsorbs and fixes the whole plastic barrel, the electric push rod 1411 controls the positioning push plate 1413 to separate from the barrel body. After the electric telescopic rod 13 drives the positioning push plate 1413 to move vertically below the barrel body, the fourth motor 12 controls the load-bearing plate 142 to move away from the barrel body through the connecting plate 15.

[0035] Furthermore, a groove is formed in the upper part of the load-bearing plate 142, and a barrel body suction cup 7 is arranged in the groove. If the barrel body material is relatively soft, the barrel body suction cup 7 (for example, a vacuum suction cup) can be used to adsorb the barrel body from the bottom of the barrel.

[0037] It can be understood that in this embodiment, the fifth motor 112 described can drive the ball screw 113 to rotate, and the ball slider 114 can move on the rotating ball screw 113.

[0038] In an embodiment of the present invention, as Figure 1 and Figure 2 shown, the water injection device 5 may include: a pump body 51, a water injection pipe 52 and a water injection head 53.
