Description

TECHNICAL FIELD

[0001] The utility model belongs to sheet production equipment technical field especially relates to a double hydraulic system of push chain clamp movement. BACKGROUND

[0002] The production process of the bidirectional stretching plastic sheet requires that the sheet, after being stretched in the longitudinal direction, enters the equipment for stretching in the transverse direction. The working principle of the equipment for stretching in the transverse direction is to clamp the sheet with chain clamps on both sides, and then the sheet enters the equipment for stretching in the transverse direction. The chain clamps move along the guide rails designed in the equipment for stretching in the transverse direction, and gradually widen the sheet to realize the transverse widening of the sheet. After the sheet is stretched in the longitudinal direction, the two sides are not linear but present a wavy shape. The deviation rectifying equipment detects the movement of the edges of the sheet, and synchronously pushes the chain clamps to move along with the changes in the edges of the sheet, so that the chain clamps effectively clamp the edges of the sheet at all times. The equipment for pushing the chain clamps to move is a small hydraulic station. Once the hydraulic station malfunctions, the sheet will be separated from the chain clamps, resulting in a broken sheet, and even the machine will stop.

[0003] In the prior art, once the hydraulic station malfunctions, the sheet will be separated from the chain clamps, resulting in a broken sheet, and the production line cannot resume normal operation in a short time. As a result, a large number of scrap sheets will accumulate in the workshop. The existing treatment method is to replace the standby hydraulic station online, which takes a long time and causes great losses. At this time, the common countermeasures are to replace the hydraulic station and reduce the losses, which will affect the production efficiency of the production line. SUMMARY

[0004] The purpose of the utility model embodiment is to provide a double hydraulic system for pushing chain clamps to move, which can quickly switch the hydraulic stations and ensure the rapid and normal operation of the production line.

[0005] The utility model embodiment is implemented in the following manner:

[0006] A double hydraulic system for pushing chain clamps to move comprises two hydraulic stations, four electromagnetic valves and an electromagnetic valve seat. The four electromagnetic valves are sequentially arranged and installed on the electromagnetic valve seat. Two connection terminals of one hydraulic station are connected to two electromagnetic valves, and the two electromagnetic valves are connected to two ends of a total power input. Two connection terminals of another hydraulic station are connected to another two electromagnetic valves, and the other two electromagnetic valves are connected to the two ends of the total power input.

[0007] The two connection terminals of the hydraulic station are a connection plate.

[0008] The hydraulic stations are respectively connected to the power transmission of the chain clamps.

[0009] The utility model embodiment can stop one faulty hydraulic station by switching the electromagnetic valves, start the standby hydraulic station, realize the online quick switching function, quickly restore the function of the hydraulic station, re-clamp the sheet, and reduce the losses.

[0013] A dual hydraulic system for moving a chain clamp includes: two hydraulic stations, four solenoid valves and solenoid valve seats. The four solenoid valves are arranged sequentially on the solenoid valve seats. Two terminals of one hydraulic station are respectively connected to two solenoid valves, which are respectively connected to the two ends of the main power input. Two terminals of the other hydraulic station are respectively connected to two other solenoid valves, which are respectively connected to the two ends of the main power input.

[0014] The hydraulic station has two terminal blocks.

[0015] Each of the hydraulic stations is connected to the chain clamp power transmission.

[0016] like Figure 1 As shown in the embodiment of this utility model, the device consists of two hydraulic stations and a valve group with switchable oil circuits. Hydraulic station 1 and hydraulic station 2 are used, and the valve group consists of valve seats and four solenoid valves: solenoid valves 1, 2, 3, and 4. When using hydraulic station 1, simply energize solenoid valves 1 and 3 simultaneously, and de-energize valves 2 and 4. To switch to hydraulic station 2, simply de-energize solenoid valves 1 and 3 first, and then energize valves 2 and 4 simultaneously for a quick switch. This enables online rapid switching and reduces abnormal losses in the hydraulic system.
