[0040] The specific implementation modes of the present invention are described in detail below with reference to the accompanying drawings.

[0041] One of the purposes of the present invention is to fully automatically mark, cut and remove defective film areas containing metal.

[0042] like Figure 1 , Figure 2 As shown, an automatic film cutting system 100 for an extruder glue feeder proposed in an embodiment of the present application is composed of a metal detector 10 , a marking device 20 , an automatic cutting device 30 and a glue feeder conveyor belt device 40 .

[0043] The glue supply machine conveyor belt device 40 is configured to convey the film along the conveyor belt at a first speed in a first direction A1. The metal detector 10, the marking device 20, and the automatic cutting device 30 are arranged along the running direction of the conveyor belt of the glue supply machine conveyor belt device 40. The automatic cutting device 30 is arranged on the glue supply machine conveyor belt device 40 at an angle, so that the extension direction of the automatic cutting device 30, that is, the second direction A2, forms any angle greater than 0 degrees and less than 90 degrees with the first direction A1, for example, any angle between 30 degrees and 60 degrees. Preferably, it is 45 degrees.

[0044] like Figure 3 , Figure 4 , Figure 5 As shown, the automatic cutting device 30 includes a cutting knife part and an anvil part 33, which are arranged in parallel. The two ends of the cutting knife part and the two ends of the anvil part can be fixed on the frame of the glue supply machine conveyor belt device 40 respectively, for example Figure 8 As shown, the anvil 331 of the anvil part 33 is fixed to two sides of the frame of the glue supply machine conveyor belt device 40 through two supports 3321 and 3322 respectively.

[0045] The cutting knife part cutting knife walking mechanism 31 and the cutting knife lifting and rotating mechanism 32 arranged on the cutting knife walking mechanism 31, the cutting knife of the cutting knife lifting and rotating mechanism 32 is aligned with the upper surface of the knife anvil 331. The cutting knife part cutting knife walking mechanism 31 drives the cutting knife lifting and rotating mechanism 32 to walk at a second speed to cut the film. The second speed needs to match the first speed to achieve that the extension direction of the incision formed by cutting the film is perpendicular to the first direction A1 in which the film is transported.

[0046] The matching of the first speed and the second speed can be determined according to the size of the first angle. For example, if the first angle is 45 degrees, the first speed is the same as the second speed, i.e., they are synchronized. If the first angle is 30 degrees or 60 degrees, the relationship between the first speed and the second speed is determined according to the trigonometric function so that the two are synchronized, so that the cutter lifting and rotating mechanism cuts the film at an angle perpendicular to the first direction.

[0047] For this reason, the structure of the cutter walking mechanism 31 is as follows: Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 and Fig.13As shown, it includes two supports 311 fixedly connected to the frame of the glue supply machine conveyor belt device 40, and the two supports 311 are respectively fixedly connected with columns 312; a long strip frame 313 arranged across the glue supply machine conveyor belt device 40 is fixed between the two columns 312, and a walking slide rail 314 extends laterally on the side of the frame 313. One end of the walking drive shaft 317 is coupled to the output end of the walking reduction motor 315, and is orthogonally coupled to the bearing 316 on the frame 313 to support the walking drive shaft 317, and the other end of the walking drive shaft 317 is coupled to a driving synchronous pulley 318 and a tightening sleeve 319. The driving synchronous pulley 318 is arranged at the first end of the frame 313, and the driven synchronous pulley is arranged at the second end of the frame. The driving synchronous pulley and the driven synchronous pulley jointly drive the synchronous belt 3121 to rotate. A plurality of synchronous belt support rollers 3120 can also be arranged along the frame to provide auxiliary support for the synchronous belt.

[0048] The first end of the synchronous belt 3121 is fixed to the first synchronous belt pressure plate 3124, and the other end is fixedly connected to the second synchronous belt pressure plate 3125. The first synchronous belt pressure plate 3124 and the second synchronous belt pressure plate 3125 are respectively fixedly connected to the bottom surface of the L-shaped base of the traveling trolley 3113 through the first tensioning bracket 3123 and the second tensioning bracket 3126. The two tensioning brackets 3123 and 3126 are connected by tensioning bolts 3122, so that the tension of the synchronous belt can be adjusted by adjusting the spacing of the tensioning brackets through the tensioning bolts 3122.

[0049] The inner side of the L-shaped base of the walking trolley 3113 is provided with a walking slider 3112, and the walking slider 3112 is matched with the walking rail 314. Thus, the synchronous belt can drive the walking trolley to move along the frame 313 guided by the walking rail 314.

[0050] A drag chain bracket 3119 is arranged on the outer side of the synchronous belt, and a drag chain 3118 is arranged on the drag chain bracket 3119. The drag chain is used to provide an air pipe and a power line for the cutter lifting and rotating mechanism.

[0051] A set of buffers 3116 and limit bolts 3117 are fixed on the upper surfaces of the two ends of the frame 313 to limit the extreme positions of the trolley in two directions. A set of proximity switches 3110 and travel switches 3111 are respectively arranged on the upper surfaces of the two ends of the frame to provide signals when the trolley reaches the extreme position.

[0052] like Figure 3 As shown, the travel trolley 3113 carries the cutter lifting and rotating mechanism 32. The cutter lifting and rotating mechanism 32 includes a cutter lifting unit and a cutter rotating unit. Fig. 20, Fig.21 , Fig. 22 , Fig.23 and Fig.24 As shown, it includes a pair of cylinder brackets 3211 fixed upright on the top surface of the L-shaped body of the traveling trolley, and a cylinder tail seat 3212 is fixedly connected to the cantilever of each cylinder bracket 3211, and the cylinder tail seat is fixedly connected to the cylinder 321 that is uprightly arranged and suspended outside the top surface of the L-shaped body of the traveling trolley. A joint bearing 3214 is arranged at the end of the cylinder rod of the cylinder for connecting the cutter rotating unit. Each cylinder is supplied with air through a three-way air pipe joint 3216 arranged on the top surface of the L-shaped body of the traveling trolley, and the three-way air pipe joint 3216 is connected to the air pipe carried by the drag chain 3118. Each cylinder is also connected to a one-way throttle valve 3215 to control the movement speed of the cylinder.

[0053] The cylinder is fixedly connected to the cutter rotating unit via a joint bearing 3214 at the end of its cylinder rod, for example, by bolts.

[0054] The cutter rotating unit is as follows: Fig.14 , Fig.15 , Fig.16 , Fig.17 , Fig.18 , Fig.19 As shown, it includes a motor mounting plate 322 and a unit mounting plate 323 that are fixed together, and one end of the motor mounting plate 322 is rotatably coupled to the cutter reduction motor 326. The unit mounting plate 323 is provided with two ears 3231, and the ears have threaded holes that can be fixedly connected to the joint bearing 3214 at the end of the cylinder rod, so that the whole can be driven up and down by the lifting cylinder 321. The back of the unit mounting plate 323 is provided with a lifting guide rail 324 extending in the up and down direction. The lifting guide rail 324 cooperates with the lifting guide slider 3114 provided on the outer side of the L-shaped body of the walking trolley 3133, so that the unit mounting plate 323 can be guided to move in the up and down direction. A bearing support 3214 is provided at the lower part of the unit mounting plate 323, a pair of bearings 3223 are fitted in the bearing support, a cutter shaft 3225 is coupled to the bearing 3223, and the portion of the cutter shaft 3225 extending from the bearing support 3224 is sequentially coupled to a cutter driven synchronous pulley 3226, a cutter mounting seat 3229, a cutter 3227, a cutter pressing plate 3228, and a shaft end pressure cover 3220. The cutter is coupled through the cutter shaft 3225, a cutter driven pulley 3226 is coupled to the cutter shaft 3225, and the cutter driven pulley 3226 and the cutter driving pulley 327 are coupled through a cutter synchronous belt 328 to form a cutter belt transmission mechanism, and the cutter belt transmission mechanism can be covered as a whole by a protective cover 3233 connected to the unit mounting plate 323.

[0055] The cutter drive pulley 3241 is coupled to the main shaft 3261 of the cutter reduction motor 326 and is driven by the cutter reduction motor 326. A limit seat 3234 can be provided on the unit mounting plate 323, and a limit bolt 3235 that can be adjusted up and down is matched on the limit seat 3234. The limit bolt 3235 corresponds to the position of the mechanical limit plate 3218 that extends laterally on the cutter lifting unit, thereby controlling the upward limit position of the cutter rotation unit. The cutter drive pulley 327 can be pressed against the main shaft 3261 of the cutter reduction motor by a pressing plate 113271. In addition, a tensioning roller 3222 can be provided on the unit mounting plate 323 to tension the cutter synchronization 328 belt.

[0056] In this way, when the cutter is cutting, the direction of the cutter's movement is 45° to the direction of film conveying, and the speed of the cutter and the glue feeder in the film conveying direction are synchronized to cut off unqualified films. The floating roller 4 is driven by a long-stroke cylinder and can swing to a nearly vertical position below the glue feeder's driving roller, and the cut unqualified films can automatically slide to the ground platform. The anvil component is located directly below the cutter's cutting path, at a 45° angle to the conveyor belt's glue feeding direction, and is used to support the conveyor belt and film directly below the cutting path. The upper surface of the anvil is a finely processed surface, and after leveling, it can ensure that the cutter cuts the film at a consistent depth during the cutting process.

[0057] like Figure 2 As shown, the cutter travel mechanism is driven by a reduction motor and a synchronous belt to move the travel trolley, which is guided by a linear slide rail; proximity switches and travel switches are used at both ends of the travel to control the reduction motor to stop for active limit, and hydraulic buffers and adjustment bolts are used for passive mechanical limit; a support roller is provided at the bottom of the synchronous belt, and a synchronous belt tensioning mechanism is provided at the connection between the lower surface of the travel trolley and the synchronous belt; a drag chain device is provided on the outer side parallel to the synchronous belt to carry cables and air pipes;

[0058] The lifting and lowering of the cutter is guided by a pair of linear slide rails, and the lifting and lowering actions are realized by two cylinders; at the end of the downward stroke of the cutter, the limit adjustment bolt and the mechanical limit plate are used to adjust the position of the cutter to the film; when the cutter reaches the cutting position, the cutter can start to rotate and move after the proximity switch detects feedback; the rotation power of the cutter is driven by the reduction motor through the synchronous belt, and the synchronous belt is equipped with a tensioning device; the synchronous belt and the cutter are equipped with safety protection covers;

[0059] The rotary reduction motor is mounted on the motor mounting plate, and the motor mounting plate is mounted on the rotary mounting plate. A linear guide rail is installed on the back of the rotary mounting plate, which is driven up and down by a cylinder. The limit bolt is used to adjust the downward stroke position of the cutter. The rotary power of the cutter is driven by the reduction motor through the synchronous pulley and synchronous belt. The synchronous belt is equipped with a tensioning device to adjust the tightness. The synchronous belt and the cutter are equipped with safety protection covers. The cutter shaft is supported by bearings and bearing supports. The cutter is installed on the cutter mounting seat and fixed by a pressure plate and bolts.

[0060] The cutting knife travel mechanism adopts linear guide rail and synchronous belt drive, which runs smoothly and with low noise. The synchronous belt is equipped with a tensioning mechanism, which can adjust the tightness of the synchronous belt. There are proximity switches and travel switches at both ends of the stroke to detect the limit, and there are gas spring buffers and mechanical limits, which ensures safe and reliable operation. There is a drag chain on the outside of the synchronous belt to carry the air pipe and cable, and the wiring is neat and convenient.

[0061] The cutter lifting mechanism is driven by a cylinder and guided by a linear slide rail, which allows for rapid and stable lifting. The downward cutting stroke of the cutter is adjusted by an adjustment bolt to adjust the depth of the cutter's film cutting. The cutter's lifting position is detected and fed back by a proximity switch to ensure safe operation. The cutter's rotating mechanism is driven by a synchronous belt, which allows for stable operation. The synchronous belt is also equipped with a tensioning mechanism. The synchronous belt and cutter are equipped with protective covers to ensure safe operation.

[0062] The system of the present application may also include an automatic marking device, in which a swing arm driven by a cylinder swings, a roller installed at the front end of the swing arm presses on the film surface and rolls continuously, and chalk pressed to the roller surface by a spring marks unqualified films; cut films are automatically removed: the floating roller adopts a long-stroke cylinder and can swing to Figure 1 In the vertical position, the cut unqualified films can automatically slide from the conveyor belt of the glue supply machine to the ground platform below.

[0063] The automatic cutting device proposed in the present application can realize the full-automatic cutting and removal of unqualified films without stopping the glue supply machine, and has overall structural priority.

[0064] The above-mentioned embodiment is an example of the present invention. Therefore, the present invention is not limited to the embodiment, but may be an example other than the embodiment. Various modifications may be made in consideration of design, etc. without departing from the true spirit and scope of the present invention.
