Specifically, the pressure sensor and the controller are electrically connected through a wire, the designer sets the pressure sensor on a side of the turntable 120 away from the base 110 according to actual needs, the pressure sensor is used for detecting the weight of a sample to be packaged placed on the turntable 120 and outputting a corresponding signal to be transmitted to the processor, the processor judges whether the sample to be packaged exists on the turntable 120 according to the signal, and the first driving element 210 is turned on or turned off according to the corresponding signal. In the design, the processor judges whether the sample to be packaged is placed on the turntable 120 according to the output signal of the pressure sensor, and properly controls the opening and closing of the first driving element 210, so that the real-time operation is not required to be carried out manually, and the automatic control of the winding machine 100 is realized.

The specific workflow of the clamping device 200 is as follows:

after a carrier places a sample to be packaged on the turntable 120, a start switch of the winding machine 100 is pressed, a pressure-output sensing device firstly detects whether a product 300 to be packaged exists on the turntable 120, if yes, a signal is output, a controller controls a first driving element 210 to be started, the first driving element 210 drives a main driving screw 221 connected with the first driving element to rotate, the main driving screw 221 rotates to drive a lifting platform 222 connected with the main driving screw to do ascending motion to a certain preset height (the clamping block 230 extends out of the turntable 120 and is used for clamping the product 300 to be packaged, and before the equipment is put into use, the preset height can be adjusted according to different products 300 to be packaged), after the lifting platform 222 moves in place, the first driving element 210 stops moving, then the controller controls a second driving element 223 to be started, the second driving element 223 drives an auxiliary driving screw 224 connected with the second driving element 223 to rotate, the auxiliary driving screw 224 rotates to drive the clamping block 230 connected with the auxiliary driving screw 224 to close to the lifting platform along the axis of the auxiliary driving screw 224 222 until the clamping block 230 abuts against the outer wall surface of the product 300 to be packaged, and the second driving element 223 stops, so that the relative fixation between the product 300 to be packaged and the turntable 120 can be realized.

As shown in fig. 6, the second aspect of the present application provides a fully automatic winding machine 100, which can effectively achieve the relative fixation of the position between the product 300 to be packaged and the turntable 120, and enhance the stability of the product 300 to be packaged placed on the turntable 120, so as to ensure the effective packaging of the product 300 to be packaged by the packaging film.

The full-automatic winding machine 100 comprises a base 110, a turntable 120, a film frame lifting device and the clamping device 200, wherein the turntable 120 can rotate relative to the base 110, and the film frame lifting device comprises a column 140 arranged on one side of the base 110 and a film frame lifting structure arranged on the column 140. Specifically, the turntable 120 is rotatably connected to the base 110 through the third driving motor 130, the upright column 140 is provided with an adjusting groove along the vertical direction, the film frame lifting mechanism 150 is slidably connected to the adjusting groove, and the packaging film is detachably connected to the film frame lifting mechanism 150.
