[0009] As a preferred technical solution of this application, the moving frame assembly includes a frame, a cable-laying motor, a guide rail fixing plate, a spindle assembly mounting platform, a winding motor, and a lead screw and nut fixing plate. The spindle assembly mounting platform is fixed at the top of the frame, and the motor on the moving frame assembly is mounted on the surface of the spindle assembly mounting platform. The guide rail fixing plate is mounted at the bottom of the frame, and the guide rail fixing plate is connected to the fixed base frame assembly. The winding motor and the cable-laying motor are respectively mounted on the inner wall of the frame by bolts and threads. The lead screw and nut fixing plate is mounted in the middle of the bottom of the frame.

Figures 1-11As shown, the cantilever winding and unwinding device includes a main shaft assembly 1, a movable frame assembly 2 installed at one end of the main shaft assembly 1, and a fixed base frame assembly 3 installed at the other end of the movable frame assembly 2. The main shaft assembly 1 includes a tensioning support plate 11, a main shaft 12, a tensioning guide sleeve 13, a tensioning cylinder 14, a rotary joint 15, a synchronous pulley set 16, and a main shaft bearing seat 17. The rotary joint 15 is threadedly installed at the end of the main shaft 12, and the rotary joint 15 is connected to the output end of the motor. The motor is threadedly installed on the movable frame assembly 2. The main shaft 12 is close to the rotary joint. One side of the head 15 is fitted with a main shaft bearing seat 17 and a synchronous pulley set 16, and a synchronous pulley set 16 is arranged between the two sets of main shaft bearing seats 17. A tensioning cylinder 14 is threadedly installed at the end of the main shaft 12, and a tensioning guide sleeve 13 is connected to the end of the tensioning cylinder 14 and sleeved on the surface of the main shaft 12. A tensioning support plate 11 is threadedly installed at the end of the tensioning guide sleeve 13. The moving frame assembly 2 includes a frame 21, a wire feeding motor 22, a guide rail fixing plate 23, a main shaft assembly mounting platform 24, a winding motor 25, and a lead screw nut fixing plate 26. A spindle assembly mounting platform 24 is threaded onto the top of frame 21, and a motor from the movable frame assembly 2 is mounted on the surface of the spindle assembly mounting platform 24. A guide rail fixing plate 23 is threaded onto the bottom of frame 21, and the guide rail fixing plate 23 is connected to the fixed base frame assembly 3. A winding motor 25 and a wire guide motor 22 are respectively threaded onto the inner wall of frame 21 via bolts. A lead screw and nut fixing plate 26 is installed in the middle of the bottom of frame 21. The fixed base frame assembly 3 includes a lead screw and nut assembly 31, a wire guide wheel assembly 32, a linear guide rail 33, and... The support base 34 has a wire guide wheel assembly 32 installed on one side end, a lead screw nut assembly 31 installed in the middle of the support base 34, and a lead screw nut fixing plate 26 installed on the surface of the lead screw nut assembly 31. Linear guide rails 33 are installed on both sides of the support base 34 and are connected to the winding motor 25. The output end of the wire laying motor 22 is connected to the output end of the lead screw nut assembly 31 through a belt. The output end of the winding motor 25 is connected to the synchronous pulley group 16 through another belt.

[0035] The equipment consists of two parts: winding and cable laying. The winding motor 22 and the take-up motor 25 are controlled by two servo motors, respectively. The winding is achieved by a reducer driving the main shaft 12 to rotate through a sprocket drive. The winding machine uses a paper tube as the roll. The paper tube is fixed in an "umbrella" structure. The tensioning cylinder 14 pushes the tensioning guide sleeve 13 to move along the main shaft 12. The tensioning guide sleeve 13 is connected to three tensioning support plates 11 through a connecting support plate. When it moves axially, it pushes the paper tube tensioning support plates 11 to open, thereby tightening and fixing the paper tube.

[0036] The machine uses Mitsubishi servo motors for the wire laying motor 22 and guide rail fixing plate 23. The control system adopts a motion control system, and the parameters are set on the touch screen. It is recommended that the manual turntable tensioning mechanism be equipped with a paper tube. All main shaft motors are equipped with servo motors to ensure fast start-up response and smoother stopping. Each machine system is independent and the equipment is highly interchangeable. It can automatically rewind and lay wire according to the extruder speed. When setting the data, you only need to manually set the product line width, and the machine will automatically lay wire according to the set width. After the machine starts automatically, it enters the automatic state without human operation. Only when the required roll material is reached will the human participate in manual unloading. Pneumatic tensioning facilitates loading and unloading.

[0037] The fixed base assembly 3 is installed on the spindle assembly 1 and drives the spindle assembly 1 to move back and forth for the wire laying process. The spindle assembly 1 is installed on the spindle assembly mounting platform 24. This assembly is fixed to the linear guide rail 33 of the fixed base assembly 3 by the guide rail fixing plate 23, and is connected to the lead screw nut assembly 31 of the base frame by the lead screw nut fixing plate 26. After the wire laying motor 22 is started, the wire laying motor 22 drives the lead screw nut assembly 31 to move through the belt. The lead screw nut assembly 31 drives the moving frame assembly 2 to move through the lead screw nut fixing plate 26. The moving frame assembly 2 drives the winding motor 25 to move. The winding motor 25 drives the linear guide rail 33 to move, so that the moving frame assembly 2 slides.

Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
