[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The PVA water-soluble film intelligent cutting device of the present invention utilizes the floor space of the machine more efficiently by vertically arranging the entire structure, avoiding the problem of the existing structure occupying a large overall floor space, and utilizing the L-shaped structure of the mounting plate and the base for installation, laying the foundation for the vertical installation of the device, thereby improving the overall combat effectiveness utilization rate and user experience of the device.

[0018] 2. The PVA water-soluble film intelligent cutting device of the present invention, by setting a first cylinder and an upper clamping plate, takes advantage of the rapid response of the cylinder. When the user controls the material receiving motor to stop working through an external control button (the control button is installed at the input end of the PLC through a wire, and the control button adopts a DS426 model control button), it can be accurately and quickly triggered to achieve elongation. The distance sensor installed on the surface of the upper clamping plate detects the state of the film clamping by the upper clamping plate in real time, thereby improving the response speed of the device after the feeding is completed and reducing the response time.

[0019] 3. The PVA water-soluble film intelligent cutting device of the present invention sets an electric heating box and a cutting wire, uses an electric heating tube to energize the cutting wire to provide a heat source, so that the temperature of the cutting wire is increased, and utilizes the characteristic of uniform heating of the graphene thermal conductive film to make the temperature of the outer surface of the cutting wire at a similar level. The cylinder front body is used to push the cutting wire to produce displacement, and the high-temperature cutting wire will cut the film body at the moment of contact with the film body, thereby achieving severance.

[0020] 4. The PVA water-soluble film intelligent cutting device of the present invention is provided with a third cylinder and a lower clamping plate. When the film needs to be cut, the upper clamping plate and the lower clamping plate will be driven by the PLC at the same time, and extend forward from the default position (the cylinder is fully retracted and loaded as the default position). At this time, the movement trajectory of each two symmetrically installed cylinders is opposite movement. After the upper and lower clamping plates are clamped, since the upper and lower clamping plates are respectively located above and below the cutting line, the film body at the cutting line area is the film body clamped by the upper and lower clamping plates, that is, the upper part of the film body here is not affected by the feeding structure to generate film feeding, nor is it affected by the film discharging structure to generate film rolling. Therefore, it can directly and accurately contact the cutting line at a fixed position, thereby making it easier to be cut.

[0021] 5. The PVA water-soluble film intelligent cutting device of the present invention is provided with an end head and a shell, and an annular groove and a concave groove are opened on the surface of the end head. The port of the cutting wire passes through the annular groove and is wrapped inside the concave groove. After repeated wrapping, the aluminum wire can be fixed, and then the protrusion inside the shell is clamped through the groove on the surface of the end head to achieve fixation. Then, the thread on the outer wall of the shell and the side wall of the electric heating box are screwed together to achieve fixed heat conduction, thereby improving the heat conduction efficiency and uniformity.

[0040] A connecting plate 38 is welded to one end face of the third mounting plate 16, and the connecting plate 38 is parallel to the mounting plate 2. A first cylinder 19 is welded to one side face of the mounting plate 2 and one side face of the connecting plate 38, and an upper clamping plate 20 is welded to the front end of the first cylinder 19; a second cylinder 21 is mounted on one side face of the mounting plate 2 and below the first cylinder 19, and the second cylinders 21 are symmetrically distributed on the surface of the mounting plate 2, and an electric heating box 22 is clamped to the front end of each of the second cylinders 21, and a cutting line 23 is installed between the two electric heating boxes 22; a third cylinder 24 is welded below the second cylinder 21 and on one side face of the mounting plate 2, and the third cylinder 24 is symmetrically welded to the surfaces of the mounting plate 2 and the connecting plate 38; a lower clamping plate 25 is clamped to the front end of the third cylinder 24; A bottom extension column 26 is symmetrically welded below the third cylinder 24 and on the side surface of the mounting plate 2, and a material receiving panel 27 is installed at the front end of each of the bottom extension columns 26 by screws, and a material receiving roller 28 is installed between the two material receiving panels 27 by bearings, and the material receiving roller 28 is driven by a material receiving motor 29; a fourth cylinder 30 is welded on the upper end surface of the base 1, and a top plate 21 is installed on the upper end surface of the fourth cylinder 30 by screws, and a guide rail 33 is symmetrically installed on the upper end surface of the top plate 21, and an auxiliary guide rail 34 is symmetrically installed on one end of the guide rail 33 and located on the upper end surface of the top plate 21 by screws, and a membrane clamp 32 is slidably connected to the surface of the top plate 21 and the surface of the auxiliary guide rail 34; a mounting head 35 is screwed through the surface of the electric heating box 22, and a heat conductive head 36 is snapped on the inner surface of the mounting head 35.

[0041] The user connects the device to an external control power supply, and the user passes the PVC water-soluble film roll to be cut (hereinafter referred to as the film roll), which is fixed on the surface of the transmission column 5, and is rotated by the first motor 6. At the same time, the two second rotating motors 10 respectively drive the two nip rollers 9 to work, and the upper surface of one nip roller 9 is higher than the other nip roller 9. The upper surface of the two nip rollers 9 is contacted with one surface of the film body respectively. After passing through the nip roller, the film body is driven by the third rotary motor 14 to rotate the feed roller 13. The number of the feed rollers 13 is at least two and one of the feed rollers 13 is lower than the upper surface of the other feed roller 13. The feed roller 13 is located on the outside of the nip roller 9. After being transmitted by the feed roller 13, the film body enters the positioning roller 17 driven by the rotary motor 18. The number of the positioning rollers 17 is at least two. The upper surfaces of every two positioning rollers 17 are on the same horizontal line. The positioning roller 17 is located in the middle position from the mounting plate 2 to the connecting plate 38. After being transmitted by the positioning tube 17, the film body falls vertically and finally contacts the receiving cylinder placed on the surface of the receiving roller 28 installed at the bottom of the device. The receiving roller 28 is driven to rotate by the receiving motor 29 (the motor is connected to the output of the PLC through an L298N driver module). The film body is wound on the surface of the winding drum. After the film is rolled, the user controls the winding motor 29 to stop rotating through the external control button. The winding motor 29 sends a signal to the PLC when it stops rotating. After the PLC detects that the winding motor 29 stops rotating, it controls the first motor 6 to stop rotating. At this time, the feeding end stops feeding and the receiving end stops receiving. At this time, the PLC controls the electric heating tube 37 to start heating. The heating temperature is limited by the temperature input by the temperature controller. After heating to a predetermined temperature, the machine will stop heating. After the first motor 6 stops rotating, the PLC determines that the winding is completed according to the electrical signal of stopping working fed back by the first motor 6, thereby controlling the pressing roller 9, the feeding roller 13 and the positioning roller 17 to stop working; at this time, the two first cylinders 19 are driven by the PLC to start extending forward.At the same time, the two third cylinders 24 are driven by the PLC to extend forward, and the first cylinder 19 and the third cylinder 24 respectively push the two upper clamps 20 and the two lower clamps 25 to clamp the membrane. The distance sensor detects the distance between the upper clamp 20 and the lower clamp 25 and determines whether the clamping is completed. After determining that the clamping is completed, the PLC controls the second cylinder 21 to drive the electric heating box 22 to move forward. The distance between the two electric heating boxes 22 is equal to the width of the mounting plate 2. The width of the mounting plate 2 must be greater than the width of the membrane. Along with the movement of the electric heating box 22, the cutting line 23 is displaced and contacts the membrane at the same time. Since the outer wall of the cutting line 23 is hot, the membrane will be broken by the heat when it contacts the membrane, thereby completing the cutting. The distance sensor on the surface of the electric heating box 22 determines that the cutting is completed (the position of the electric heating box 22 contacts the surface of one side of the connecting plate 38 to determine that the cutting is completed). After the cutting is completed, the third cylinder 24 and the second cylinder 21 are reset, and the first cylinder 19 is inconvenient to keep the current position. Since the cutting line 23 is located below the first cylinder 19, after the cutting is completed, part of the film body is still left below the first cylinder 19. At this time, the fourth cylinder 30 extends upward, driving the top plate 2 31 to extend, and the proximity sensor on the surface of the top plate 2 31 senses that the film clamp is close to the broken part of the film body (the top plate 2 31 is located at the midline position from the inner side of the mounting plate 2 to the inner side of the connecting plate 38. The proximity sensor is connected to the input end of the PLC through a wire. The proximity sensor adopts the APDS-9900 model proximity sensor). The film clamp 32 on the surface of the guide rail 33 and the auxiliary guide rail 34 moves in opposite directions to clamp the film body below the first cylinder 19. After the clamping is completed, the first cylinder 19 is reset, the fourth cylinder 30 retracts, and the PLC starts to control the first motor 6 to be energized, and the device starts a new winding and cutting. ;

[0042] In summary: the present invention utilizes the floor space of the machine more efficiently by vertically arranging the entire structure, avoiding the problem of the existing structure occupying a large overall floor space, and utilizes the L-shaped structure of the mounting plate and the base to lay the foundation for the vertical installation of the device, thereby improving the overall combat effectiveness utilization rate and user experience of the device.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
