Detailed Description

To explain the technical content, structural features, achieved objects and functions of the present invention in detail, the following detailed description is made with reference to the accompanying drawings. The positional relationship between the upper, lower, left, right, front and rear in this embodiment corresponds to the positional relationship of the wrapping machine shown in fig. 1.

As shown in FIG. 1, the cotton baler includes a bale case 11, a bale press mechanism 12, an operating lever 13, and a control circuit 14.

The bale case 11 includes a case body 111 and a door 113, a cotton insertion opening 112 is provided on a front side portion of the case body 111, and the door 113 is rotatably mounted on the front side portion of the case body 111. The top of the box 111 is provided with an opening 114. The cotton pressing mechanism 12 comprises a hydraulic oil cylinder 121 mounted on the top of the box body 111, a pressing head 122 mounted on a piston rod of the hydraulic oil cylinder 121 and penetrating through the opening 114, an oil tank 123 for storing hydraulic oil, an input oil path 124 and an output oil path 125 for communicating the oil tank 123 and the hydraulic oil cylinder 121, an oil pump 126 communicated with the oil tank 123, and a motor 127 for driving the oil pump 126 to operate. When the hydraulic oil cylinder 121 acts, the driving pressure head 122 realizes the downward pressing and upward moving actions, thereby completing the cotton pressing action. The input oil path 124 and the output oil path 125 are respectively provided with a valve 128, the operating lever 13 is in transmission connection with each valve 128, and is operated by a user to open or close the valve 128, so that hydraulic oil in the oil tank 123 is input into the hydraulic oil cylinder 121 through the input oil path 124 or hydraulic oil in the hydraulic oil cylinder 121 is output back into the oil tank 123 through the output oil path 125, and the pressure head 122 is controlled to complete the downward pressing or upward moving action. The control circuit 14 is electrically connected to the motor 127, and a normally open switch 141 for a user to operate is disposed on the control circuit 14, and the normally open switch 141 is a push button switch. The oil pump 126, the motor 127 and the operating lever 13 are all arranged on the upper portion of the oil tank 123, a pump oil port of the oil pump 126 is communicated with the input oil path 124, and the motor 127 is in transmission connection with the oil pump 126.

When the user presses the button switch with one hand, the control circuit 14 is in an electrically on state, the motor 127 is started to operate, the oil pump 126 is driven to operate, the operating rod 13 is operated with the other hand to open the valve 128 on the input oil path 124, so that the hydraulic oil in the oil tank 123 is input into the hydraulic oil cylinder 121, and the press head 122 completes the pressing action, so that the cotton in the bale case 11 is compacted; when the user operates the lever to open the valve 128 on the output oil path 125, the hydraulic oil in the hydraulic cylinder 121 is output back into the oil tank 123, so that the ram 122 completes the upward movement. Meanwhile, the user must operate the cotton pressing mechanism with two hands to realize the pressing or moving action of the cotton pressing mechanism, and even if the user only uses one hand to operate one of the normally open switch and the operating lever 13, the cotton pressing mechanism cannot work. Therefore, the condition that the user presses the hands when the user only operates the cotton packing machine with one hand can be effectively avoided, and the cotton packing machine is safer and more reliable in operation.

The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose of the embodiments is to enable people skilled in the art to understand the contents of the present invention and to implement the present invention, which cannot limit the protection scope of the present invention. All equivalent changes and modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
