[0039] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] Reference Figures 1-9 An automatic slitting and cutting mechanism for aluminum-plastic film includes an unwinding and dust removal component 1, and a film cutting component 5 and a film pulling and transferring component 9 which are sequentially arranged at the discharge position of the unwinding and dust removal component 1; the unwinding and dust removal component 1 includes an unwinding component 2, a dust removal component 3 and a roller assembly 4, the roller assembly 4 is located between the unwinding component 2 and the dust removal component 3, the roller assembly 4 includes a roller shaft 403 and a roller groove 402, and the first cutter 401 is detachably installed on the roller shaft 403.

[0041] By adopting the above technical solution, through the arrangement of the unwinding dust removal component 1, the sheet film cutting component 5, and the film pulling and transporting component 9, the sheet film slitting knife distance, the distance of the film splicing platform and the position of the aluminum-plastic film core can be changed to produce aluminum-plastic films of different size requirements, thereby expanding the compatibility of the mechanism. Through the roller cutter assembly 4 and the film pulling and transporting component 9, the aluminum-plastic film can be effectively cut and moved, and a four-out effect can be achieved, which saves space and greatly improves production efficiency. Through adjustments in the process, the machine structure is made compact, which effectively saves production time and greatly improves production capacity.

[0042] Multiple first cutters 401 are located above the roller cutter groove 402. The roller cutter shaft 403 drives the first cutter 401 up and down through the cylinder to switch between the tool changing position and the working position to provide tool changing space. The roller cutter groove 402 is driven by a speed regulating motor, and a dust collection component 13 is installed below the roller cutter groove 402.

[0043] Furthermore, when the number of first cutters 401 is set to three, they can cooperate with the roller groove 402 to cut four sheets of film on a roll of aluminum-plastic film. The first cutter 401 is installed on the roller shaft 403 using a quick-release design, which is more convenient for replacing the blade's wearing parts. A scale is provided on the roller shaft 403 to facilitate the precise position adjustment of the first cutter 401. The roller shaft 403 is driven by a cylinder to switch only between the tool changing position and the working position, providing a safe and convenient tool changing space; the dust collection component 13 includes a second brush, a suction pump and a dust bag, which is conducive to timely removal of debris in the roller groove 402.

[0044] The unwinding assembly 2 includes a base 210, a frame 209, a stepper motor 201 and an inflatable shaft 202. The stepper motor 201 is fixed to the frame 209, and the output end of the stepper motor 201 is connected to the inflatable shaft 202 through a synchronous wheel and a synchronous belt.

[0045] Furthermore, the inflatable shaft 202 is driven by a stepper motor 201 in conjunction with a synchronous wheel and a synchronous belt to perform unwinding. The stepper motor 201 can adopt an open-loop circuit control to save costs. The aluminum-plastic film roll is fixed on the inflatable shaft 202, and the inflatable shaft 202 is connected to an external air source device. By controlling the pipeline valve on the air source device, the shaft on the surface of the inflatable shaft 202 is raised or retracted, which facilitates the replacement of the aluminum-plastic film roll core.

[0046] A belt connecting platform 204 is provided below the inflatable shaft 202, and a plurality of rollers 206 are installed on the belt connecting platform 204. Film pressing cylinders 207 are provided on both sides of the belt connecting platform 204, and a gravity roller 205 is provided below the belt connecting platform 204. The base 210 and the frame 209 are slidingly connected through a screw module. A hand wheel 208 is installed on the base 210, and a plurality of sensors 203 are installed on the unwinding path of the frame 209.

[0047] Furthermore, there are at least two sensors 203, such as a photoelectric sensor and a color mark sensor. The photoelectric sensor is responsible for correcting the deviation of the aluminum-plastic film, and the color mark sensor is responsible for sensing whether there is a foreign object at the joint, thereby judging whether this section of the aluminum-plastic film is usable (the specific structure of the above-mentioned sensor 203 can be easily realized by those skilled in the art according to relevant technologies and will not be described in detail here); through the action of the film pressing cylinders 207 on both sides of the splicing platform 204, when the aluminum-plastic film core is replaced, it is only necessary to activate the film pressing cylinders 207 to press the aluminum-plastic film tightly, and then use a knife to cut the aluminum-plastic film. Since the broken parts have pressure The film cylinder 207 is pressed so that the front and rear mechanisms are not affected. After replacing the new aluminum-plastic film core, the new and old aluminum-plastic films are glued together with tape and the film can be used normally. When the aluminum-plastic film passes through the gravity roller 205, the gravity roller 205 plays a role in tension control, so that the aluminum-plastic film maintains a constant tension, ensuring production efficiency and the surface quality of the aluminum-plastic film coil. The gravity roller 205 is connected to the frame 209 through the cylinder, so that the gravity roller 205 can self-adjust according to the change of the aluminum-plastic film tension. By operating the hand wheel 208 in conjunction with the screw module, the frame 209 can be moved back and forth.

[0048] The dust removal assembly 3 includes an active brush 301 and a driven brush 302. The active brush 301 is driven by a speed-regulating motor, and the active brush 301 and the driven brush 302 are connected via a transmission wheel and a transmission belt.

[0049] Furthermore, the active brush 301 is driven by the speed regulating motor to rotate the driven brush 302 , and both the active brush 301 and the driven brush 302 are equipped with a dust collecting assembly 13 , which can clean the surface of the aluminum-plastic film passing by.

[0050] The film cutting component 5 is located at the discharge end of the dust removal component 3. The film cutting component 5 includes a cutter seat component 6 and a film clamping component 7. The film clamping component 7 is arranged parallel to the cutting position of the cutter seat component 6.

[0051] The cutter seat assembly 6 includes a cutter cylinder 602 and a second cutter 601 installed on the support part in an upper and lower arrangement. The upper cutter of the second cutter 601 is driven up and down by the cutter cylinder 602; the film clamping assembly 7 includes a mounting seat 705 and a base plate 706. The mounting seat 705 and the base plate 706 are slidably connected by a guide rail 707. A limit plate 701 is installed on the mounting seat 705. An adjustable adjustment block 702 is provided on the limit plate 701. A three-axis cylinder 703 is provided on the adjustment block 702. The telescopic end of the three-axis cylinder 703 is connected to a pressure block 704. The second cutter 601 is provided with a cutting pressure plate 8 at the feeding position.

[0052] Furthermore, the cutter seat assembly 6 also includes a support frame that supports the cutter and other parts. The lower cutter of the second cutter 601 is in a fixed state. When the upper cutter of the second cutter 601 moves downward, it engages with the lower cutter of the second cutter 601 to cut the aluminum-plastic film; the bottom of the lower cutter is equipped with a dust removal assembly 3, which can promptly absorb the aluminum-plastic film debris cut by the cutter; the limiting plate 701 and the adjustment block 702 in the film clamping assembly 7 can guide the aluminum-plastic film entering the sheet film cutting component 5. The function is to clamp the aluminum-plastic film through the three-axis cylinder 703, and the surface of the pressure block 704 on the three-axis cylinder 703 is equipped with rubber to prevent the surface of the aluminum-plastic film from being damaged. Since the aluminum-plastic film has been evenly cut into four parts at the front unwinding and dust removal part, four three-axis cylinders 703 are used here to clamp the aluminum-plastic film; the guide rail 707 connected to the bottom plate 706 is driven by the cylinder to push the mounting seat 705 to move, so that the aluminum-plastic film unwound at the back is sent out toward the film-pulling transfer component 9, so that the aluminum-plastic film protrudes from a part of the cutting knife, which is convenient for subsequent film pulling.

[0053] The film pulling and transferring component 9 includes a film pulling clamping assembly 10, a film transfer platform 11 and a waste box 12. The film transfer platform 11 includes a linear module 1105, a vertical plate 1103, a variable distance module 1102 and a suction plate 1101. The variable distance module 1102 is connected to the linear module 1105 through the vertical plate 1103. A telescopic cylinder 1104 is installed on the vertical plate 1103 to drive the variable distance module 1102 to move up and down.

[0054] Furthermore, since it is a one-out-four method, four suction plates 1101 are required. The suction plates 1101 are installed on the variable-pitch module 1102, and the position of the suction plates 1101 can be adjusted according to the size of the aluminum-plastic film; the variable-pitch module 1102 is driven by the telescopic cylinder 1104 to complete the up and down movement of the vertical plate 1103. This is so that when the aluminum-plastic film is to be received, the variable-pitch module 1102 is moved upward, and after the aluminum-plastic film is received, the variable-pitch module 1102 is moved downward. In this way, when the aluminum-plastic film is sent to other positions, it will not interfere with other mechanisms. The linear module 1105 at the bottom of the film transfer platform 11 is used to complete the forward and backward movement of the film transfer platform 11, thereby realizing the film receiving and film transfer actions; the waste box 12 is used to collect waste film.

[0055] The film pulling clamping assembly 10 includes a horizontal plate 1003 , on which a plurality of clamping jaws 1001 are mounted, and the clamping jaws 1001 are provided with a clamping plate 1002 . The horizontal plate 1003 is connected to the supporting portion via a screw slide module 1004 , which is driven by a servo motor 1005 .

[0056] Furthermore, the clamping jaws 1001 and the cylinder are equipped with a rubber-coated clamping plate 1002, which can improve the stability of the film clamping. Since the aluminum-plastic film has been evenly divided into four parts by the unwinding and dust removal component 1 in the front, four cylinders are used here to clamp the aluminum-plastic film; the cylinder is installed on a long horizontal plate 1003, and its position can be adjusted according to the size of the aluminum-plastic film; the screw slide module 1004 at the bottom of the film clamping is driven by the servo motor 1005 to complete the forward and backward movement of the film clamping assembly 10, thereby realizing the action of clamping and pulling the film.

[0057] To sum up, through the structural settings of the unwinding dust removal component 1, the sheet film cutting component 5, and the film pulling and transporting component 9, the sheet film slitting knife distance, the distance of the film splicing platform and the position of the aluminum-plastic film core can be changed according to production requirements, so that aluminum-plastic films of different size requirements can be produced, which expands the compatibility of the mechanism. Through the roller cutter assembly 4 and the film pulling and transporting component 9, the aluminum-plastic film can be effectively cut and moved, and the effect of one out of four can be achieved, which saves space and greatly improves production efficiency. Through adjustments in the process, the machine structure is made compact, which effectively saves production time and greatly improves production capacity.

[0058] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
