Continue to refer to Figure 4It should be noted that the through slot 31 is provided on the bearing plate 101, and the plurality of support plates 33 are located inside the through slot 31 to avoid mechanical interference when the support plates 33 move; A test assembly 2 is arranged on the bearing plate 101, which is used to provide pressure when the plastic bucket is tested; As shown in the drawings, Figures 1-3 The test assembly 2 includes a lead screw 210 rotatably arranged on the bearing plate 101, and a driving motor 211 fixedly arranged on the bearing plate 101, and the output end of the driving motor 211 is provided with a first belt set 212 together with the bottom of the lead screw 210, a cross beam 26 is threadedly arranged on the lead screw 210, and two sets of guide rods 29 are fixedly arranged on the bearing plate 101, and the cross beam 26 is slidingly arranged on the two sets of guide rods 29; Further, under the driving of the driving motor 211, the lead screw 210 is driven to rotate through the first belt set 212, the cross beam 26 is driven to move up and down along the axial direction of the lead screw 210, and the moving direction is fixed under the action of the guide rods 29; Two sets of support frames 21 are fixedly arranged on the bearing plate 101, the support frames 21 are spliced by a plurality of steel plates, and the support frames 21 are arranged outside the guide rods 29, and a top frame 22 is fixedly arranged on the two sets of support frames 21;

So that when the cross beam 26 moves, the pressing plate 23 is driven to move downward at the same time, and pressure is applied to the plastic bucket on the bearing assembly 3, and when the pressing plate 23 is in contact with the plastic bucket, the pressing plate 23 is supported upward by the plastic bucket, and force is applied to the pressure sensor 28, at this time the first supporting rod 24 drives the supporting spring 25 to stretch, and the pressure data of the plastic bucket is monitored in real time and uploaded in real time, and after the test is completed, the pressing plate 23 can be reset under the action of the restoring force of the supporting spring 25;

[0021] Embodiment two:

[0022] When the vehicle is used to transport the plastic bucket, multiple sets of plastic buckets are usually stacked and placed in the carriage. At this time, the bottom plastic bucket is in a long-time pressure state. During the driving process of the vehicle, due to the periodic vibration caused by the rotation of the engine and the transmission shaft and the ups and downs of the road surface, the carriage can be inclined. Long-term vibration and pressure may have additional effects on the plastic bucket. Although the above embodiment can simulate the internal situation of the carriage, it can only simulate the test situation in the static state and cannot simulate the situation during the transportation of the vehicle. In order to solve this problem, the vibration assembly 5 is arranged on the bearing assembly 3, which is used to vibrate the bearing assembly 3. As shown in Figure 4 The vibration assembly 5 includes a vibration motor 53 fixedly installed at the bottom of the bottom plate 36, and multiple sets of cross rods 54 are fixedly arranged at both ends of the bottom plate 36. The cross rods 54 are slidably penetrated in the baffles of the cover plate 32, so that the bottom plate 36 fixedly arranged with the cover plate 32 is changed to be slidably arranged. And a protrusion (not marked in the figure) is arranged on the cross rod 54, and a compression spring 55 is arranged between the protrusion and the baffle, so as to buffer the bottom plate 36 when the vibration motor 53 is started, so as to avoid damage to the bottom plate 36 and the cover plate 32 due to the hard connection therebetween. Referring to Figure 4A cylinder 51 is fixedly installed on the bottom plate 36, and the output end of the cylinder 51 is hingedly connected with a top plate 52, the top plate 52 is provided with a groove 521, and the bottom of the end of the support plate 33 close to the top plate 52 is fixedly installed with a vertical rod (not shown in the figure), which is slidingly arranged in the groove 521; It should be noted that one end of the vertical rod extends out of the bottom of the groove 521, and the end of the vertical rod extending out of the groove 521 has a pad to be fastened with the top plate 52 to prevent the vertical rod from coming out of the groove 521; And the support plate 33 fixedly connected with the sliding block 41 is changed to be rotatably connected, as Figure 6 The end of each group of sliding blocks 41 has an extension block (not marked in the figure), and the end of the support plate 33 away from the top plate 52 is rotatably installed on the extension block; Further, under the driving of the cylinder 51, the top plate 52 drives the plurality of support plates 33 to rotate along the rotation point of the support plate 33 and the extension block, so that the support plate 33 and the plastic barrels thereon are inclined at a certain angle; As described above, in use, the test assembly 2 drives the pressing plate 23 to move downward to generate a certain pressure on the plastic barrels, the vibration motor 53 is started to drive the bottom plate 36 to vibrate, thereby driving the bearing assembly 3 to vibrate as a whole, and under the action of the compression spring 55, part of the vibration can be buffered, thereby simulating that the plastic barrels are vibrated under a certain pressure when the vehicle transports the plastic barrels, and the cylinder 51 is started to drive the top plate 52 to lift, thereby driving the plurality of support plates 33 to rotate, thereby driving the plastic barrels to be inclined at a certain angle, to simulate that the carriage is inclined at a certain angle when the vehicle encounters a bumpy road during transportation.

[0023] Embodiment three:

[0024] When the stacked or stacked plastic barrels are vibrated and bumpy, other plastic barrels stacked on the bottom plastic barrels may be offset, and when the stacked plastic barrels are offset, uneven extrusion may occur between them, which may cause the barrel to deform, crack or even break; The above embodiment can simulate the situation when the vehicle encounters vibration and bumping during transportation, but it cannot simulate the situation when the stacked or stacked plastic barrels are vibrated and bumpy, and other plastic barrels stacked on the bottom plastic barrels may be offset; In order to solve this problem, a moving assembly 6 is arranged on the test assembly 2, which is used for the movement of the pressing plate 23; In this embodiment, the fixed connection between the pressing plate 23 and the first support rod 24 is changed to active arrangement, as Figures 8-9 As shown in the figure, a plurality of through holes 62 are formed in the pressing plate 23, and the second support rod 241 penetrates the through holes 62, and the diameter of the through hole 62 is greater than the diameter of the second support rod 241; The moving assembly 6 comprises a gasket 641 fixedly installed at the bottom of the plurality of second supporting rods 241, the bottom of the gasket 641 is fixedly installed with a pneumatic cylinder 64 connected with the PLC system, the output end of the pneumatic cylinder 64 is fixedly installed with a wedge block 61, a cavity (not marked in the figure) is formed in the second supporting rod 241, and the wedge block 61 is slidingly arranged in the cavity, so as to be driven by the pneumatic cylinder 64 to move in the cavity; Two groups of top blocks 63 are slidingly arranged in the second supporting rod 241, and a plurality of clamping grooves 631 are formed in the pressing plate 23, and part of the top blocks 63 are located in the clamping grooves 631; It should be noted that the wedge block 61 has inclined ends on both sides, and the two groups of inclined surfaces gradually approach each other in the upward direction; And the end of the top block 63 close to the wedge block 61 has an inclined surface 65 which is matched with the inclined end of the wedge block 61, and the two groups of top blocks 63 are jointly provided with a return spring 66; In the initial state, the pneumatic cylinder 64 is in the retracted state, at this time, the two groups of top blocks 63 are in the extended state under the extrusion of the inclined end of the wedge block 61, and are clamped in the clamping grooves 631, so that the pressing plate 23 and the second supporting rod 241 are fixedly connected, at this time, the return spring 66 is in the stretched state; When the pneumatic cylinder 64 is extended, the wedge block 61 is driven to move upward, at this time, the two groups of top blocks 63 approach each other under the action of the restoring force of the return spring 66, at this time, a gap is formed between the clamping grooves 631 and the top blocks 63, at this time, the pressing plate 23 and the second supporting rod 241 are slightly separated; As Figure 6 shown, a trigger switch 56 is arranged on one of the sliding blocks 41, the trigger switch 56 is connected with the PLC system, the trigger part of the trigger switch 56 is in contact with the bottom of the supporting plate 33, so that when the supporting plate 33 rotates, the trigger switch 56 is triggered synchronously, the PLC system receives the signal and controls the pneumatic cylinder 64 to extend, driving the two groups of top blocks 63 to retract; If the plastic bucket deforms under a constant pressure in the first embodiment, the tests of the second embodiment and the third embodiment are not needed, if the plastic bucket does not deform under a constant pressure, the actual simulation test can be carried out by the second embodiment and the third embodiment, that is, the plastic bucket is vibrated and inclined at a certain angle under the constant pressure by the second embodiment; Therefore, when the support plate 33 rotates, the plastic bucket is tilted at a certain angle, the trigger switch 56 is triggered, the PLC system receives the signal, and the air cylinder 64 is controlled to extend, driving the two sets of top blocks 63 to retract. At this time, a certain gap is generated between the clamping groove 631 and the top block 63. At this time, the top block 63 is not completely separated from the clamping groove 631, so that when the simulation pressing plate 23 and the plastic bucket are tilted, the pressing plate 23 can move in the direction of the tilting tendency of the pressing plate 23 under the action of gravity, so that the center of gravity of the pressing plate 23 and the plastic bucket is offset, so as to simulate that when the stacked plastic buckets are subjected to vibration or tilting, the upper plastic bucket is offset to cause the center of gravity to be offset; It should be noted that because the pressing plate 23 is offset under pressure, the moving distance of the pressing plate 23 is small, and the space for retracting the two sets of top blocks 63 can completely provide the pressing plate 23 to move, and even if the pressing plate 23 moves to the limit position, the top block 63 will not be separated from the clamping groove 631; After the test is completed, the air cylinder 64 is reset to drive the two sets of top blocks 63 to synchronously extend and re-enter the clamping groove 631, and correct the offset pressing plate 23, until the top block 63 is completely clamped into the clamping groove 631, thereby driving the pressing plate 23 to reset.

[0025] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
