Detailed ways

Refer to attached drawing. The portable baling machine without a lifting and rotating handle includes a fixed grasping handle 100, a steering gear motor 200, a tensioning belt working motor (obstructed by the casing in the figure and not shown) and a welding working motor 300. The steering gear motor 200 is used for The steering gear is driven to rotate forward or reverse to drive the first actuator 11 to rotate clockwise or counterclockwise. When rotating counterclockwise, the second actuator 12 is driven to rotate clockwise and passes through the relevant parts of the second actuator 12 122 drives the swing arm 500 to open (unlock), and compresses the spring 501 through the pressure block 121 on the second actuator 12 . Reference numeral 503 is a stroke detection switch, which cooperates with the second actuator 12 and is used to prevent the swing arm 500 from rotating to an excessive position and provide signal feedback. When locked, the steering gear motor 100 drives the first actuator 11 to rotate clockwise, the second actuator 12 is driven by the spring to rotate counterclockwise, and the associated part 122 drives the swing arm 500 to rotate in the opposite direction to the locking angle, where At the locking angle, the strap is clamped by the tensioning wheel of the tensioning station 401 of the portable baler and the tooth plate connected to the swing arm below it and cannot fall out of the baler. When the swing arm rotates to the contact locking angle, The tooth plate leaves the tensioning wheel so that the strap can be loaded into or taken out of the portable baling machine. Reference number 402 is a welding work station.

The portable baling machine control device of the present invention is provided with an inching switch on the lower front of the grip handle 100, so The inching switch adopts a self-resetting switch 20. The self-resetting switch 20 is a switch that is opened by inching operation and automatically resets and closes after releasing the inching pressure. The self-resetting switch 20 is connected to the controller of the portable baling machine, and the starting of the steering gear motor 200 is controlled solely by the self-resetting switch 20 . The controller uses a single-chip microcomputer.

As shown in Figure 6, after starting up, the controller always detects the self-reset switch signal. Once it detects the signal corresponding to the self-reset switch 20 being turned on, it determines whether the stroke detection switch 503 is in place (whether it is activated by the second actuator 12 function), if it is not in place, the steering gear motor 200 is controlled to run in the unlocking direction. As shown in Figure 4, the first actuator 11 rotates counterclockwise, and the second actuator 12 and the swing arm 500 are driven to rotate counterclockwise and open; such as If a signal corresponding to the self-resetting switch being turned on is not detected, the steering gear motor 200 is controlled to run in the corresponding locking direction, and the first actuator 11 leaves the second actuator 12. As shown in Figure 4, the second actuator 12 The swing arm 500 can rotate counterclockwise under the action of the compression spring 501; the stroke detection switch 503 is used to detect whether the swing arm 500 rotates to the limit angle in the unlocking direction.

The portable baling machine is also provided with a second switch 22. The second switch 22 is connected to the controller. The second switch 22 serves as a start switch in the automatic tightening and welding automatic continuous modes. After starting, the second switch 22 is connected to the controller. The tight belt working motor and the welding working motor 300 run in sequence and in sequence according to the set time. The second switch 22 is not responsible for starting and shutting down the steering gear motor 200 .

The portable baler is also provided with a third switch 23. The third switch is connected to the controller. The third switch serves as a starting switch for the welding motor in the separate control modes of tensioning and welding. During tensioning and welding, In the welding independent control mode, the second switch 22 serves as the start switch of the tensioning working motor 300; the third switch 23 is also not responsible for starting and shutting down the steering gear motor 200.

When the steering gear motor runs in the unlocking direction, the timing of turning off the steering gear is determined by time or current intensity. When the running time reaches the set time or the current intensity exceeds a certain value, the steering gear motor is turned off; when the steering gear motor is pressed in the locking direction, the steering gear motor is turned off. The direction of operation is also determined by time or current intensity. When the operation reaches the set time or the current intensity exceeds a certain value, the steering gear motor is turned off. Since the controller is always detecting the signal of the self-resetting switch, this method can not only reduce the number of sensors, but also ensure the normal operation of the portable baler.

When the steering gear motor 200 runs in the unlocking direction or is in a stopped state, once the controller does not detect a signal corresponding to the self-resetting switch 20 being turned on, it controls the steering gear motor 200 to run in the locking direction. In this way, when the strap is installed After the belt is finished, the portable baler can enter the locked state by loosening your fingers, which makes the operation more convenient. In normal times, the portable baler is always in the locked state, which can protect the internal structure and can be connected with the belt. Attach to the strap to prevent the portable baler from being knocked down.

When the steering gear motor 200 runs in the locking direction (your finger does not touch the self-reset switch 20 at this time), in case of emergency, as long as the self-reset switch 20 is touched immediately, the controller detects the corresponding self-reset switch 20 The signal that is turned on controls the steering gear motor 200 to stop. When it is stopped, it returns to the aforementioned situation. If the controller detects a signal corresponding to the self-resetting switch 20 being turned on, it will determine whether the stroke detection switch 503 is in place, such as is not in place, that is, the steering gear motor 200 is controlled to run in the unlocking direction. If the signal corresponding to the self-resetting switch 20 being turned on is not detected, the steering gear motor 200 is controlled to run in the corresponding locking direction and returns to the locked state, so that You can start working immediately if needed.

The optimal position of the self-resetting switch 20 is such that when the grip handle 100 is held in hand, the index finger can operate it conveniently.

The above are only specific embodiments of the present invention, but the structural features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the field of the present invention are covered by the protection scope of the present invention. among.
