[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a slitting machine for aluminum-plastic film materials, comprising a base 1. A feeding structure, a slitting structure and a discharging structure are arranged on the top of the base 1. The slitting structure is located between the feeding structure and the discharging structure. When the slitting machine is in use, the feeding structure can be used to transport the aluminum-plastic film materials, the slitting structure can be used to cut and strip the aluminum-plastic film materials, and the discharging structure can be used to transport the cut aluminum-plastic film materials.

[0024] The feeding structure includes a double-headed screw 2 movably connected to the base 1 and a rotating motor 7 fixedly connected to the base 1. The end of the output shaft of the rotating motor 7 is connected to the end of the double-headed screw 2 through a reducer. When the rotating motor 7 rotates, the rotating motor 7 can drive the double-headed screw 2 to rotate.

[0025] The outer rings at both ends of the double-headed screw rod 2 are threadedly connected to the moving rod 3, and the bottom of the moving rod 3 is in contact with the top of the base 1. Through the setting of the moving rod 3, when the double-headed screw rod 2 rotates, the base 1 can limit the moving rod 3, so that the moving rod 3 moves in the direction of the double-headed screw rod 2, and the distance between the two moving rods 3 can change.

[0026] The top of the inner side of the moving rod 3 is movably connected with the upper feeding roller 4, and the inner side of the moving rod 3 is connected with the support block 19 through the hydraulic telescopic rod 120. The support block 19 is located below the upper feeding roller 4. The inner side of the support block 19 is movably connected with the lower feeding roller 5. Under the action of the hydraulic telescopic rod 120, the distance between the upper feeding roller 4 and the lower feeding roller 5 can be changed. The two upper feeding rollers 4 and the two lower feeding rollers 5 are connected by the telescopic rod. In some embodiments of the present application, the telescopic rod includes a rectangular sleeve connected to one upper feeding roller 4 or one lower feeding roller 5 and a rectangular rod 6 movably connected to the inner cavity of the rectangular sleeve. The other end of the rectangular rod 6 is connected to another upper feeding roller 4 or another lower feeding roller 5. Through the setting of the telescopic rod, the two upper feeding rollers 4 can move synchronously, and the two lower feeding rollers 5 can move synchronously.

[0027] The upper feed roller 4 is movably connected to the moving rod 3 through a rotating shaft, and the rotating shaft is movably connected to the moving rod 3, the upper feed roller 4 is fixedly connected to the rotating shaft, the lower feed roller 5 is located below the upper feed roller 4, and the lower feed roller 5 is movably connected to the support block 19 through another rotating shaft, the other rotating shaft is fixedly connected to the lower feed roller 5, and the other rotating shaft is movably connected to the support block 19; a rotating motor 21 is fixed to the top of a moving rod 3 and the outer side of a support block 19, and the output shaft of the rotating motor 21 is connected to the rotating shaft through a transmission structure 1. In some embodiments of the present application, the transmission structure 1 includes a synchronous wheel 1 fixedly connected to the end of the output shaft of the rotating motor 21, a synchronous wheel 2 fixedly connected to the outer ring of the rotating shaft, and a synchronous belt, and the synchronous wheel 1 is connected to the synchronous wheel 2 through a synchronous belt transmission. Through the setting of the rotating motor 21, when the rotating motor 21 rotates, it can drive the corresponding rotating shaft to rotate through the transmission structure 1, and the rotating shaft can drive the upper feeding roller 4 or the lower feeding roller 5 to rotate. The rotating upper feeding roller 4 or the lower feeding roller 5 can drive the other upper feeding roller 4 or the lower feeding roller 5 to rotate through the connecting rod.

[0028] From the above description of the feeding structure, it can be seen that the distance between the two upper feeding rollers 4 and the two lower feeding rollers 5 can be adjusted according to needs. When in use, the feeding structure can adapt to aluminum-plastic film materials of various widths, thereby improving the adaptability of the slitting machine. Moreover, the distance between the upper feeding rollers 4 and the lower feeding rollers 5 can be changed, so that the feeding structure can adapt to aluminum-plastic film materials of various thicknesses.

[0029] The strip structure includes a bracket connected to the base 1 and a support rod 10 connected to the bracket through a hydraulic telescopic rod 39. The bracket includes a fixed frame 31 and a movable frame 22, the fixed frame 31 is fixedly connected to the base 1, the top of the fixed frame 31 is movably connected to the cutting rod 32, the outer ring of the top of the fixed frame 31 is fixedly connected to the rotating motor 48, the output shaft end of the rotating motor 48 is fixedly connected to one end of the cutting rod 32, and through the setting of the rotating motor 48, the rotation of the rotating motor 48 can drive the cutting rod 32 fixedly connected thereto to rotate. The movable frame 22 is connected to the base 1 through a hydraulic telescopic rod 6 23, and the bottom end of the movable frame 22 is fixedly connected to the end of the output shaft of the hydraulic telescopic rod 6 23, the other end of the hydraulic telescopic rod 6 23 is fixedly connected to the base 1, and the top of the movable frame 22 is movably connected with a clamping rod, and the other end of the cutting rod 32 is provided with a clamping groove adapted to the clamping rod. Through the setting of the hydraulic telescopic rod 6 23 and the clamping rod, the extension and retraction of the hydraulic telescopic rod 6 23 can change the position of the clamping rod, so that the clamping rod and the cutting rod 32 can be clamped or separated. When the clamping rod is clamped with the cutting rod 32, it is convenient to rotate the cutting rod 32. When the clamping rod is separated from the cutting rod 32, it is convenient to replace the cutting knife 30 movably sleeved on the cutting rod 32.

[0030] A slide groove is provided on one side of the cutting rod 32, and a moving block 39 is evenly and movably connected in the inner cavity of the slide groove. Two adjacent moving blocks 39 are connected by a hydraulic telescopic rod four 18. Under the action of the hydraulic telescopic rod four 18, the distance between the two adjacent moving blocks 39 can be changed. A hydraulic telescopic rod five 17 is fixed to one end of the slide groove, and the other end of the hydraulic telescopic rod five 17 is fixedly connected to a moving block 39 close to it. Through the setting of the hydraulic telescopic rod five 17, the extension and retraction of the hydraulic telescopic rod five 17 can change the position of the moving block 39.

[0031] The outer ring of the cutting rod 32 is movably sleeved with a cutting knife 30, and the cutting knife 30 is connected to the moving block 39 by bolts. A sound detection sensor 33 is fixed to the side of the cutting knife 30 close to the moving block 39. Through the setting of the sound detection sensor 33, when the slitting machine is in use, the sound detection sensor 33 can be used to detect the sound generated by the cutting knife 30 cutting the aluminum-plastic film material. When the cutting knife 30 is sharp, the contact area between the cutting knife 30 and the aluminum-plastic film material is small, and the resistance is small. At this time, the cutting sound is sharp. As the cutting time increases, the cutting knife 30 will gradually wear out, so that the contact area between the cutting knife 30 and the aluminum-plastic film material increases, and the resistance of the cutting knife 30 will also increase. At this time, the cutting sound will become dull. Therefore, the wear of the cutting knife 30 can be understood according to the change of the sound. When the sound becomes dull and harsh, it means that the cutting knife 30 needs to be polished.

[0032] Hydraulic telescopic rods 3 9 are fixed to the top of both the fixed frame 31 and the movable frame 22, the support rod 10 is clamped with the top of one hydraulic telescopic rod 3 9, and the support rod 10 is movably connected to the top of another hydraulic telescopic rod 3 9. Preferably, the support rod 10 is movably connected to the top of the hydraulic telescopic rod 3 9 connected to the fixed frame 31.

[0033] The outer ring of the support rod 10 is movably sleeved with a grinding structure, and the number of the grinding structures is the same as the number of the cutting blades 30. The cutting blades 30 are located below the middle of the grinding structure. The grinding structure includes a lifting ring 26 movably sleeved with the support rod 10, a connecting frame 27 is fixed at the bottom of the lifting ring 26, a plug rod 25 is fixed to one side of the bottom of the connecting frame 27, and a plug piece 40 adapted to the plug rod 25 is fixed to the side of the moving block 39 close to the plug rod 25. Through the setting of the hydraulic telescopic rod 39, the extension and retraction of the hydraulic telescopic rod 39 can change the distance between the plug rod 25 and the plug piece 40. When the plug rod 25 is engaged with the plug piece 40, the movement of the moving block 39 can drive the grinding structure and the cutting blade 30 to move, so that the position between the grinding structure and the cutting blade 30 can remain unchanged, which is convenient for the grinding structure to grind the cutting blade 30.

[0034] The connecting frame 27 and the support rod 10 are in a state of magnetic attraction. In some embodiments of the present application, electromagnets are fixed to the top of the connecting frame 27 and the bottom of the support rod 10. With this arrangement, when the insertion rod 25 is separated from the insertion piece 40, the position of the grinding structure can remain unchanged, which facilitates the use of the grinding structure.

[0035] Springs 38 are fixedly connected to both sides of the bottom end of the connecting frame 27, and a grinding stone 36 is fixed to the other end of the spring 38. The cutting knife 30 is located between the two grinding stones 36. A positioning rod 34 is fixed to the side of the grinding stone 36 close to the connecting frame 27, and the positioning rod 34 is movably connected to the connecting frame 27. By setting the positioning rod 34, the position of the grinding stone 36 can be limited so that the height of the grinding stone 36 can remain unchanged. An iron block 37 is fixed to the side of the grinding stone 36 close to the connecting frame 27, and electromagnets 35 are fixed to both ends of the inner side of the connecting frame 27. When the electromagnet 35 is in an energized state, the electromagnet 35 and the iron block 37 can be magnetically attracted to each other. Under the action of the suction force, the two grinding stones 36 can move away from each other. When the electromagnet 35 is in a power-off state, the two grinding stones 36 can move closer to each other under the action of the rebound force of the spring 38, so that during the grinding process of the cutting knife 30, the grinding stone 36 can contact with the cutting knife 30, which is convenient for grinding the cutting knife 30.

[0036] A burr detector 29 is fixed on one side of the connecting frame 27 close to the discharge structure. The burr detector 29 can be used to detect the cut seam of the aluminum-plastic film material, and the degree of wear of the cutting knife 30 can be determined according to the number of burrs on the cut seam.

[0037] The above-mentioned discharge structure includes an upper rotating rod and a lower rotating rod 12, the upper rotating rod is movably connected to the base 1 through a fixed rod 16, the inner side of the fixed rod 16 is connected to a driven block through a hydraulic telescopic rod 2 14, the end of the lower rotating rod 12 is movably connected to the driven block, the outer ring of the upper rotating rod is evenly fixed with an upper discharge roller, the outer ring of the lower rotating rod 12 is evenly fixed with a lower discharge roller 13, and the upper discharge roller is located above the lower discharge roller 13; a rotating motor 3 15 is fixed to the top of a fixed rod 16 and the outer side of a driven block, and the output shaft of the rotating motor 3 15 is connected to the upper rotating rod or the lower rotating rod 12 through a transmission structure 2.

[0038] The bottom of the upper discharge roller is at the same height as the bottom of the upper feeding roller 4, and the top of the lower discharge roller 13 is at the same height as the top of the lower feeding roller 5. Through the arrangement of the discharge structure, the upper discharge roller and the lower discharge roller 13 are used in coordination to transfer the cut aluminum-plastic film material away, and the portion of the aluminum-plastic film material located below the cutting blade 30 can be kept in a horizontal state during cutting, so that the cutting blade 30 can cut the aluminum-plastic film material.

[0039] The electrical components involved in this application are all prior art, and technicians in this field are familiar with their connection methods. Through these technicians, all the electrical components in this application are connected to their compatible power supplies through wires, and according to the actual situation, a suitable controller is selected to meet the control requirements. The specific connection and control sequence are described below. The electrical connection is completed in a sequential working order, and the detailed connection means are well known in the art. The following mainly introduces the working principle and process, and no further explanation of the electrical control is given.

[0040] To sum up: before using the slitting machine for aluminum-plastic film materials, the staff adjusts the distance between the two moving rods 3, the distance between the two upper discharge rollers and the distance between the two lower discharge rollers 13 according to needs, so that the upper feeding roller and the lower feeding roller 5 can contact the edge portion of the aluminum-plastic film material to be cut, and each aluminum-plastic film material after cutting can contact the upper discharge roller and the lower discharge roller 13. When the slitting machine for aluminum-plastic film materials is used, the rotating motor 21, the rotating motor 3 15 and the rotating motor 4 8 are all working, and the feeding structure and the discharging structure are used in coordination, so that the aluminum-plastic film material can be moved below the slitting structure. During the movement of the aluminum-plastic film material, the rotating motor 4 8 drives the cutting rod 32 to rotate, and the cutting rod 32 drives the cutting knife 30 to rotate, so as to cut the aluminum-plastic film material. During the cutting process, the sound detection sensor 33 detects the sound generated by the cutting knife 30 in real time, and the burr detector 29 performs burr detection on the cut seam formed after cutting. If the cutting sound is abnormal and the cutting burrs become more, the cutting knife 30 needs to be polished. During polishing, the hydraulic telescopic rod 3 9 contracts, and the hydraulic telescopic rod 3 9 contracts. The retracted rod 39 drives the grinding stone 36 to move downward until the cutting knife 30 is located between the two grinding stones 36. The electromagnet 35 on one side of the cutting knife 30 to be ground is first in a power-off state. Under the action of the rebound force of the spring 38, the grinding stone 36 can contact one side of the cutting knife 30. The rotation of the cutting knife 30 enables the grinding stone 36 to grind one side of the cutting knife 30. After the grinding of one side of the cutting knife 30 is completed, the power-off electromagnet 35 is powered on again, and the electromagnet 35 on the other side of the cutting knife 30 is in a power-off state. The other side of the cutting knife 30 can be ground. After the grinding is completed, the power-off electromagnet 35 is powered on again, and the cutting knife 30 is separated from the grinding stone 36, which is convenient for the use of the cutting knife 30.
