Problems solved by technology

[0002] In the current carton production process, most of the clamping, lifting, and deflection adjustment of the paper ring are driven by mechanical transmission, which requires 6 motors and gearboxes to realize the action. The manufacturing and installation are very complicated, the cost is high, and there is no overload protection, speed regulation, etc. Function
The hydraulic system that appeared in the market also has no pressure regulation, speed regulation, and synchronization functions.

Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0012] A shaftless support hydraulic system, as shown in Figures 1, 2, 3, 4, and 5, which includes a motor 1, a high-pressure pump 3, and an oil tank. The motor 1 is connected to the high-pressure pump 3, and the high-pressure pump is connected to the oil tank through a hydraulic oil circuit. Connected, a filter screen 2 is installed on the hydraulic oil circuit between the oil tank and the high-pressure pump 3, the high-pressure pump is connected to the main check valve 4 through the hydraulic oil line, and the hydraulic oil lines from the main check valve 4 are respectively connected to the overflow valve 16. The main decompression valve 5. Two lifting three-position four-way electromagnetic reversing valves 6. Pressure gauges; the overflow valve 16 is connected to the oil tank through the hydraulic oil circuit; each lifting three-position four-way ...

Abstract

A simple and safe shaftless support hydraulic system with overload protection comprises a motor, a high-pressure pump and an oil tank, wherein a filter gauze is arranged between the oil tank and the high-pressure pump; the high-pressure pump is connected with a master one-way valve which is connected with an overflow valve, a master pressure reducing valve, a lifting three-position four-way electromagnetic directional valve and a pressure gauge; the lifting three-position four-way electromagnetic directional valve is connected with a lifting hydraulic control one-way valve which is connected with a lifting pressure reducing valve; the lifting pressure reducing valve is connected with a lifting throttle valve which is connected with a lifting oil cylinder; the master pressure reducing valve is connected with the pressure gauge and a clamping three-position four-way electromagnetic directional valve which is connected with a clamping hydraulic control one-way valve; the clamping hydraulic control one-way valve is connected with two two-position four-way electromagnetic directional valves and a clamping oil cylinder with the valves connected with the clamping oil cylinder; moreover, the two two-position four-way electromagnetic directional valves are connected with each other through a clamping throttle valve.

Description

technical field [0001] The invention relates to a packaging machine, in particular to a shaftless support hydraulic system. Background technique [0002] In the current carton production process, most of the clamping, lifting, and deflection adjustment of the paper ring are driven by mechanical transmission, which requires 6 motors and gearboxes to realize the action. The manufacturing and installation are very complicated, the cost is high, and there is no overload protection, speed regulation, etc. Features. The hydraulic systems that appear on the market do not have the functions of pressure regulation, speed regulation and synchronization. Contents of the invention [0003] The object of the present invention is to provide a simple and safe hydraulic system for shaftless supports. [0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: a shaftless support hydraulic system, which includes a motor, a high-pressure pum...
