[0027] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0028] See also Figures 1 to 4As shown in the embodiment of this application, a valve platform for improving wire feeding stability is provided, applied to a bar baling machine. The valve platform includes at least one oil inlet P, at least one oil return port T, at least one first working oil port A, at least one second working oil port B, an oil inlet pipe 101, and an oil return pipe 102. The oil inlet P is connected to the hydraulic system; the oil return port T is used to return hydraulic oil to the hydraulic system; the first working oil port A and the second working oil port B are respectively connected to the oil ports of the actuator; the oil inlet pipe 101 is connected to the oil inlet P; the oil inlet pipe 101 is connected to the first working oil port A and the second working oil port B; the oil return pipe 102 is connected to the oil return port T; the oil return pipe 102 is connected to the first working oil port A and the second working oil port B; the oil inlet P is connected to the first working oil port A or the second working oil port B, so that the actuator rotates along a first direction or a second direction, switching between a fast feeding state and a slow feeding state.

[0029] The oil inlet P, oil return T, first working oil port A, and second working oil port B are integrated on a single valve platform. By switching the connection between the oil inlet P and the first working oil port A or the second working oil port B, the wire feeding mechanism is driven to switch between fast and slow wire feeding. Fast wire feeding improves wire feeding efficiency, while slow wire feeding eliminates errors and improves the stability and accuracy of wire feeding.

[0030] The oil inlet P is connected to either the first working oil port A or the second working oil port B, allowing the actuator to rotate in either the first or second direction, switching between fast and slow feed states. Here, the actuator is a bidirectional hydraulic motor, capable of reversing direction based on the flow of hydraulic oil. The speed of the hydraulic motor is directly proportional to the flow rate of the hydraulic oil entering it; that is, the higher the speed of the hydraulic motor, the greater the flow rate; the lower the speed of the hydraulic motor, the smaller the flow rate.

[0031] Specifically, the first rotation direction and the second rotation direction are opposite to each other; in this embodiment, the first rotation direction is clockwise and the second rotation direction is counterclockwise.

[0032] In this embodiment, there are six sets of oil inlet P, oil return T, first working oil port A, and second working oil port B. In other embodiments, the selection can be made according to specific working conditions.

[0033] The hydraulic system includes a hydraulic pump, the output of which is connected to the inlet P via a connecting pipe. The hydraulic pump, through its rotation or reciprocating motion, draws hydraulic oil from the hydraulic system and pressurizes it to a certain pressure. This high-pressure hydraulic oil is then delivered to the hydraulic motors, providing them with power.

[0034] The hydraulic system also includes an oil tank, with the return port T connected to the oil tank via a connecting pipeline, and the oil inlet of the hydraulic pump connected to the oil tank; the oil tank is used to store hydraulic oil.

[0035] In another embodiment, the valve platform for improving the stability of the feed line also includes at least one throttling damper 103, which is installed in the oil line of the first working port A or the second working port B, and is used to regulate the flow rate of hydraulic oil so that the actuator switches between a fast feed state and a slow feed state.

[0036] The following explanation uses a set of valve holes as an example:

[0037] In this embodiment, the throttling damping element 103 is installed on the oil circuit of the first working oil port A. The first working oil port A is connected to the return oil port of the hydraulic motor, and the second working oil port B is connected to the inlet oil port of the hydraulic motor.

[0038] When the hydraulic motor operates clockwise: the oil inlet P of the valve seat is connected to the second working oil port B, and the second working oil port B is connected to the oil inlet of the hydraulic motor.

[0039] The specific working principle is as follows: hydraulic oil enters the second working port B from the oil inlet P of the valve seat, and then enters the hydraulic motor through the oil inlet of the hydraulic motor, driving the hydraulic motor to rotate clockwise to achieve rapid wire feeding; then the hydraulic oil flows out from the return port of the hydraulic motor and returns to the return port T of the valve seat through the first working port A.

[0040] When the hydraulic motor operates counterclockwise: the oil inlet P of the valve seat is connected to the first working oil port A, and the first working oil port A is connected to the oil inlet of the hydraulic motor.

[0041] The specific working principle is as follows: hydraulic oil enters the first working port A from the oil inlet P of the valve seat (because the first working port A is equipped with a throttling damper 103, the orifice of the first working port A becomes smaller, thereby reducing the flow rate of hydraulic oil entering the oil inlet of the hydraulic motor); then it enters the hydraulic motor through the oil inlet of the hydraulic motor, driving the hydraulic motor to rotate counterclockwise to achieve rapid wire feeding; then the hydraulic oil flows out from the return port of the hydraulic motor and returns to the return port T of the valve seat through the second working port B.

[0042] In this embodiment, the throttling damper 103 is installed on the oil circuit of the second working oil port B. The first working oil port A is connected to the return oil port of the hydraulic motor, and the second working oil port B is connected to the inlet oil port of the hydraulic motor.

[0043] When the hydraulic motor operates clockwise: the oil inlet P of the valve seat is connected to the first working oil port A, and the first working oil port A is connected to the oil inlet of the hydraulic motor.

[0044] The specific working principle is as follows: hydraulic oil enters the first working port A from the oil inlet P of the valve seat, and then enters the hydraulic motor through the oil inlet of the hydraulic motor, driving the hydraulic motor to rotate clockwise to achieve rapid wire feeding; then the hydraulic oil flows out from the return port of the hydraulic motor and returns to the return port T of the valve seat through the second working port B.

[0045] When the hydraulic motor operates counterclockwise: the oil inlet P of the valve seat is connected to the second working oil port B, and the second working oil port B is connected to the oil inlet of the hydraulic motor.

[0046] The specific working principle is as follows: hydraulic oil enters the second working port B from the oil inlet P of the valve seat (at this time, because the throttling damper 103 is installed on the first working port B, the orifice of the first working port B becomes smaller, thereby reducing the flow rate of hydraulic oil entering the oil inlet of the hydraulic motor); then it enters the hydraulic motor through the oil inlet of the hydraulic motor, driving the hydraulic motor to rotate counterclockwise to achieve slow wire feeding; then the hydraulic oil flows out from the return port of the hydraulic motor and returns to the return port T of the valve seat through the first working port A.

[0047] The following explanation uses two sets of valve holes as an example:

[0048] The group with the throttling damper 103 installed is defined as the first group, in which a three-position four-way directional valve is installed on the throttling damper 103; the group without the throttling damper 103 installed is defined as the second group.

[0049] The oil inlet of the hydraulic motor is connected to the first working oil port A of both the first and second groups, and the oil return port of the hydraulic motor is connected to the second working oil port B of both the first and second groups.

[0050] When the hydraulic motor works clockwise: the hydraulic oil enters the first working port A of the second group from the oil inlet P of the valve seat, and then enters the hydraulic motor through the oil inlet of the hydraulic motor, driving the hydraulic motor to rotate clockwise to achieve rapid wire feeding; then the hydraulic oil flows out from the return port of the hydraulic motor and returns to the return port T of the valve seat through the second working port B of the second group.

[0051] When the hydraulic motor operates counterclockwise: hydraulic oil enters the first working port A of the first group from the oil inlet P of the valve seat (because the first working port A is equipped with a throttling damper 103, the orifice of the first working port A becomes smaller, thereby reducing the flow rate of hydraulic oil entering the oil inlet of the hydraulic motor), and then enters the hydraulic motor through the oil inlet of the hydraulic motor, driving the hydraulic motor to rotate counterclockwise to achieve slow wire feeding; then the hydraulic oil flows out from the return port of the hydraulic motor and returns to the return port T of the valve seat through the second working port B of the first group.

[0052] In another embodiment, the valve platform for improving the stability of the wire feeding also includes at least one directional valve, which is installed in the valve platform and located between the first working port A and the second working port B. The directional valve is used to switch the flow direction of the hydraulic oil so that the inlet port P is connected to the first working port A or the inlet port P is connected to the second working port B.

[0053] In another embodiment, the valve seat that improves the stability of the hydraulic feed also includes a filter installed on the oil supply line at the oil inlet P. The filter is used to filter impurities in the hydraulic oil, preventing blockage of the throttling damper 103 and the steering valve.

[0054] In another embodiment, the valve seat that improves the stability of the feed line also includes a temperature measuring element, which is installed on the inner wall of the oil inlet P of the valve seat and is used to monitor the oil temperature of the hydraulic oil.

[0055] In this embodiment, the temperature sensing element is a temperature sensor; in other embodiments, it can also be a thermocouple or an infrared thermometer. The temperature sensing element is used to detect the hydraulic oil temperature at the oil inlet P in real time, and dynamically adjust the system pressure according to the oil temperature to maintain flow stability.

[0056] In another embodiment, the valve seat that improves the stability of the feed line also includes a pressure measuring element, which is installed on the inner wall of the oil inlet P of the valve seat and is used to monitor the oil pressure of the hydraulic oil.

[0057] In this embodiment, the pressure measuring device is a pressure sensor. In other embodiments, the pressure measuring device measures the oil pressure of the hydraulic oil output by the hydraulic system to avoid damage to the hydraulic motor due to excessive oil pressure.

[0058] In a second aspect of this application, a bar baling machine is provided, including a valve platform for improving wire feeding stability and a wire feeding frame, wherein the valve platform for improving wire feeding stability is disposed on the wire feeding frame.

[0059] The valve platform has bolt holes, and the valve platform is installed on the wire feeder by bolts; the drive wire feeder mechanism switches between fast wire feed and slow wire feed, which improves the wire feed efficiency by fast wire feed and eliminates errors by slow wire feed, thereby improving the stability and accuracy of wire feed.

[0060] With significantly improved wire feeding stability, the strapping will be positioned more accurately and the tightness will be more uniform. This will directly improve the packaging quality of the bars and reduce product losses due to substandard packaging.

[0061] The efficient wire feeding function of the fast and slow feed combination valve station can reduce the downtime of the packing machine due to wire feeding problems, thereby improving the operating efficiency of the production line. Especially in large-scale production, this efficiency improvement will bring significant economic benefits to enterprises.

[0062] It will be readily understood by those skilled in the art that the aforementioned advantageous methods can be freely combined and superimposed without conflict.

[0063] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
