Description

TECHNICAL FIELD

[0001] The utility model relates to a pressing equipment field, concretely relates to a waste barrel pressing device. BACKGROUND

[0002] The factory mainly produces 58 products of three categories of acid, ketone and ester, all products are liquid, and most customers need 200 liter barrel loading, and the barrel needs to be recycled by the company, 70% of the barrels can be reused, 30% of the barrels are caused by transportation collision, cause scratch, depression, galvanized layer fall-off and other phenomena, these barrels all need to be scrapped by the factory, the scrapped barrels are cleaned and qualified and disposed by the third party, due to the large volume of the barrel, the transportation cost is much higher than the residual value of the barrel, which leads to the difficulty of the implementation of the scheme, and the factory waste barrels are more and more.

[0003] The existing scheme is to cut the barrel into four pieces by using an angle grinder, it is found that cutting causes a lot of dust and noise, the risk of cutting by the angle grinder is very high, at least 20 minutes are needed to process one barrel, and the volume is not small after being cut into four pieces, so the scheme is also difficult to implement, and the disposal of the scrapped barrels brings great problems to the factory.

[0004] Therefore, there is a need in the art for a new technical solution to solve the above problems. SUMMARY

[0005] In order to improve or solve the technical problems that the scrapped barrel is difficult to handle in the prior art, the utility model provides a waste barrel pressing device. The waste barrel pressing device comprises a pressure bearing bottom plate adapted to support a waste barrel, an upper support plate arranged opposite to the pressure bearing bottom plate, an upper pressing plate arranged between the pressure bearing bottom plate and the upper support plate in a liftable manner, a hydraulic oil cylinder connected to the upper pressing plate and configured to drive the upper pressing plate to approach or move away from the pressure bearing bottom plate, a reversing valve and an overflow valve connected to the hydraulic oil cylinder, a first position detection switch, a second position detection switch and a third position detection switch arranged on the upper pressing plate, the first position detection switch being configured to control the reversing valve to reverse when the upper pressing plate is at a first predetermined distance from the pressure bearing bottom plate, the second position detection switch being configured to control the reversing valve to reverse when the upper pressing plate is at a second predetermined distance from the upper support plate, and the third position detection switch being configured to control the overflow valve to open when the upper pressing plate is at a third predetermined distance from the pressure bearing bottom plate, the third predetermined distance being smaller than the first predetermined distance.

[0006] In the waste barrel pressing device, the upper pressing plate is driven by the hydraulic oil cylinder to move towards the pressure bearing bottom plate, so that the waste barrel on the pressure bearing bottom plate is pressed flat, facilitating the transportation of the waste barrel. The reversing valve is used for controlling the reciprocating operation of the hydraulic oil cylinder, and the overflow valve is used for releasing the oil pressure of the hydraulic oil cylinder, preventing the oil pressure from rising sharply and causing damage to the oil cylinder seal. When the first position detection switch is at a first predetermined distance from the pressure bearing bottom plate, i.e. when the waste barrel pressing is completed, the reversing valve is reversed, and the hydraulic oil cylinder drives the upper pressing plate away from the pressure bearing bottom plate. When the second position detection switch is at a second predetermined distance from the upper support, i.e. when the hydraulic oil cylinder is reset, the reversing valve is reversed, and the hydraulic oil cylinder drives the upper pressing plate to approach the pressure bearing bottom plate to press the waste barrel. When the third position detection switch is at a distance from the pressure bearing bottom plate that is less than the first predetermined distance, i.e. when the first position detection switch fails, the hydraulic oil cylinder continues to drive the upper pressing plate to move downward, the overflow valve is opened, the hydraulic oil flows back to the hydraulic oil tank, and the oil pressure is released, thereby protecting the oil cylinder seal. Through the above setting, the waste barrel pressing device of the utility model sets the first position detection switch and the second position detection switch, can realize the semi-automatic pressing of the waste barrel, and has high pressing efficiency; the third position detection switch realizes overpressure protection, the device runs stably, safely and reliably.

[0011] Further, the fourth predetermined distance is 10 mm,

[0012] Further, a just-in-place baffle suitable for abutting against the waste barrel is arranged on the pressure bearing bottom plate.

[0023] Figure 1 It is an embodiment of the utility model of a kind of waste barrel pressing device. As shown in Figure 1 One or more embodiments, the utility model of a kind of waste barrel pressing device includes frame 1, pressure bearing bottom plate 2, upper pressing plate 3, upper support 12, hydraulic cylinder 4 and position detection switch.

[0024] Continue to refer to Figure 1 Frame 1 is generally rectangular frame 1. Frame 1 is welded with H-shaped steel, and has high pressure bearing strength. H-shaped steel is arranged on the top and bottom of frame 1. Upper support 12 is arranged on the top of frame 1 for mounting and fixing hydraulic cylinder 4. Pressure bearing bottom plate 2 is arranged on the bottom of frame 1. Further, supports are arranged on the side of frame 1. Hydraulic cylinder 4 is controlled by hydraulic control box 10, and hydraulic control box 10 is mounted on the support. Further, hydraulic cylinder 4 is connected with hydraulic control box 10 through reversing valve 5 and overflow valve 6. Reversing valve 5 is used to adjust the extension and reversion of hydraulic cylinder 4, and overflow valve 6 is used to adjust the oil pressure of hydraulic cylinder 4. Hydraulic cylinder 4 is connected with upper pressing plate 3 for driving upper pressing plate 3 to rise and fall. Upper pressing plate 3 is arranged opposite to pressure bearing bottom plate 2. Waste barrels are loaded on pressure bearing bottom plate 2 by hand or machine. Hydraulic cylinder 4 drives upper pressing plate 3 to descend to crush the waste barrels. Then, reversing valve 5 is reversed, and hydraulic cylinder 4 drives upper pressing plate 3 to rise. Exemplarily, the height of waste barrel before pressing is 90 cm, and the height of waste barrel after pressing is 15 cm.

[0025] Continue to refer to Figure 1The position detection switch is installed on the upper pressing plate 3, and is a proximity switch. In one or more embodiments, the position detection switch comprises a first position detection switch 7, a second position detection switch 8 and a third position detection switch 9. The first position detection switch 7 and the second position detection switch 8 are linked with the reversing valve 5, and the third position detection switch 9 is linked with the overflow valve 6. Specifically, three positioning rods 11 are arranged on the frame 1, and the lower two positioning rods 11 correspond to the first position detection switch 7 and the third position detection switch 9 respectively, and the positioning rod 11 on the upper support 12 corresponds to the second position detection switch 8. When the upper pressing plate 3 is lowered by the hydraulic cylinder 4, when the first position detection switch 7 approaches the positioning rod 11, i.e. when the upper pressing plate 3 is at a first predetermined distance from the pressure receiving bottom plate 2, the first position detection switch 7 sends a reversing signal to the reversing valve 5, the reversing valve 5 reverses, the hydraulic cylinder 4 resets, and the upper pressing plate 3 rises; when the second position detection switch 8 approaches the positioning rod 11 on the upper support 12, i.e. when the upper pressing plate 3 is at a second predetermined distance from the upper support 12, the second position detection switch 8 sends a reversing signal to the reversing valve 5, the hydraulic cylinder 4 drives the upper pressing plate 3 to descend, and a round of work is completed; when the first position detection switch 7 fails, the upper pressing plate 3 continues to descend, and when the third position detection switch 9 approaches the positioning rod 11, i.e. when the upper pressing plate 3 is at a third predetermined distance from the pressure receiving bottom plate 2, the third position detection switch 9 sends a signal to the overflow valve 6, the overflow valve 6 opens, the hydraulic oil flows back to the oil tank, the oil pressure is released, and the oil cylinder sealing element is protected. It can be understood that the third predetermined distance is less than the first predetermined distance. Specifically, the third position detection switch 9 is higher than the first position detection switch 7 in the up-down direction by a fourth predetermined distance, i.e. the difference between the first predetermined distance and the third predetermined distance is the fourth predetermined distance, so as to control the overflow valve 6 to open when the first position detection switch 7 fails and the upper pressing plate 3 continues to descend. Exemplarily, the fourth predetermined distance can be 10 mm. Alternatively, the third predetermined distance can also be set to 8 mm, 12 mm or other suitable heights.

[0026] Continuing to refer to Figure 1 In one or more embodiments, a time delay device is arranged between the second position detection switch 8 and the reversing valve 5, and the time delay device is configured to control the reversing valve 5 to reverse after a first predetermined time. Specifically, when the upper pressing plate 3 is at a second predetermined distance from the upper support 12, the second position detection switch 8 sends a signal to the time delay device, and the time delay device sends a signal to the reversing valve 5 after a first predetermined time, and the reversing valve 5 reverses. Further, the first predetermined time ranges from 15 seconds to 60 seconds. Exemplarily, the first predetermined time is 15 seconds, 30 seconds and 60 seconds. The value of the first predetermined time depends on the loading time of the waste barrel. Further, a positioning baffle is arranged on the pressure receiving bottom plate 2, and the positioning baffle abuts against the waste barrel to position the waste barrel, so that the waste barrel faces the pressure receiving bottom plate 2 and the upper pressing plate 3.

[0027] The technical scheme of the utility model has been described in combination with the preferred embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the utility model is obviously not limited to these specific embodiments.
