[0002] Aluminum foil lunch boxes are a widely used tableware. The thickness of aluminum foil lunch boxes is generally between 0.03mm-0.20mm, and they can be divided into two types: wrinkled and wrinkle-free. They can also be divided into two types: disposable and reusable. In China, it is often called tinfoil lunch boxes. In fact, it is made of 3 series or 8 series aluminum ingot raw materials, which are cold-rolled or hot-rolled into aluminum foil mother rolls with uniform thickness, smooth surface, no pinholes, no dust particles, and no odor. It is formed by a one-time fully automatic cold stamping process using special equipment and molds.
[0003] Slitting machine is a kind of mechanical equipment that cuts wide paper, mica tape or film into multiple narrow materials.

Slitting machine is mainly used for: non-woven fabrics; mica tape, paper, insulation materials and various film materials, especially suitable for narrow strip slitting.
[0004] During the processing and slitting of aluminum foil lunch boxes, the width varies depending on the usage, so slitting is required. Since the aluminum foil is thin, it is easy to tear due to uneven force during slitting or tear at the cutter due to the winding process after cutting. In addition, the cutting width of the aluminum foil is not the same for different usage requirements. At the same time, when the winding roller is winding, the aluminum foil lunch box being slit cannot be adaptively wound according to different slitting widths, which is not conducive to the normal slitting operation of the slitting tool assembly, resulting in incision deviation, affecting the slitting accuracy and reducing the product cutting quality.

DETAILED DESCRIPTION
[0021] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example
[0022] Reference Manual Attached Figure 1 -Attached Fig. 9 A slitting device for processing aluminum foil lunch boxes comprises: a tensioning mechanism 1, which is installed on a bottom plate and is used to adjust the tension of the conveyed aluminum foil lunch box; a pressing and cutting mechanism 2, which is located between the tensioning mechanism 1 and a winding mechanism 3, and is used to press and stick the aluminum foil lunch box and simultaneously realize slitting; a winding mechanism 3, which comprises a first motor 4 disposed at both ends of a side plate, the output shaft of the first motor 4 being connected to a winding wheel 5, one end of the inner wall of the winding wheel 5 being hollow and movably connected with a telescopic rod 6, the telescopic rods 6 being connected by a first bidirectional cylinder 7, and as the first bidirectional cylinder 7 is started, the winding area on the winding wheel 5 is telescopically adjusted.
[0023] The tensioning mechanism 1 includes a second motor 8 placed on the bottom plate, the output shaft of the second motor 8 extends to the turntable 9 and the cam 10 respectively, the turntable 9 and the first slider 11 are connected by a swing rod 12, the first slider 11 is symmetrically arranged relative to the center of the inverted U-shaped plate, and the first slider 11 is provided with a first strip groove 13 along the height direction of the inverted U-shaped plate, and the first sliders 11 are connected by a first guide roller 14; Among them, both ends of the cam 10 are movably connected with an annular plate 16 fixed on the bracket 15, one end of the bracket 15 is connected to the spring rod 18 through the second slider 17, the spring rod 18 is connected with a matching limit groove along the length direction of the rectangular plate 19, and the second sliders 17 are connected by the second guide roller 20. Both ends of the swing rod 12 are connected to the turntable 9 and the first slider 11 by a rotation connection. The outer wall of the cam 10 is provided with a rotation groove connected to the inverted U-shaped plate. As the second motor 8 is started, the first slider 11 drives the first guide roller 14 to move up and down, and the second slider 17 drives the second guide roller 20 to move horizontally synchronously.
[0024] When the second motor 8 is started, it can drive the turntable 9 and the cam 10 to rotate together. During the rotation of the turntable 9, due to the rotation connection setting of the swing rod 12, the first slider 11 can be driven to move up and down in the first strip groove 13, thereby causing the first guide roller 14 to move up and down accordingly. In addition, during the rotation of the cam 10, since one end of the annular plate 16 is movably fitted with it and the other end is connected to the spring rod 18 through the second slider 17, the rotary motion of the cam 10 can be converted into a linear reciprocating motion of the second slider 17 in the limiting groove by means of the elastic restoring force of the spring rod 18, thereby allowing the second guide roller 20 to move synchronously. In this way, through the up and down movement of the first guide roller 14 and the same-direction horizontal movement of the second guide rollers 20 at both ends, the conveyed aluminum foil material can be tensioned and adjusted accordingly.
[0025] In addition, the provision of the first strip groove 13 and the limit groove can ensure that the first guide roller 14 and the second guide roller 20 are placed in a positional state during movement, and through the same-direction horizontal movement of the second guide rollers 20 at both ends, in cooperation with the first guide roller 14, "two sheets and one tight" or "two tight and one sheet" adjustment can be achieved, thereby achieving stable conveying of aluminum foil materials.
[0026] In the present invention, before the slitting operation, the aluminum foil lunch box material passes through the first guide roller 14 and the second guide roller 20 of the tensioning mechanism 1 in sequence, and then enters the pressing and cutting mechanism 2 and the winding mechanism. The tensioning mechanism 1 can adjust the tension of the aluminum foil during cutting and conveying through the first guide roller 14 and the second guide roller 20. In fact, by starting the first motor 4, the first slider 11 is driven to move up and down through the swing rod 12, that is, through the rotation of the crank connecting rod, the second slider 17 movably connected to the cam 10 is cooperated. Under the reset elasticity of the spring rod 18, the second guide rollers 20 on the second sliders 17 at both ends can achieve the same direction of horizontal movement. In this way, the aluminum foil material can not only play a corresponding tension adjustment during the conveying process, but also can perform a corresponding positive adjustment on the conveying direction, thereby ensuring the accuracy of the conveying direction, thereby ensuring stable conveying work for the cutting process. Example
[0027] Reference Manual Attached Figure 1 , Attachment Figure 2 , Attachment Figure 7 , Attachment Fig. 9 and attached Fig.10 The clamping and cutting mechanism 2 includes a third motor 21 placed on the column, the output shaft of the third motor 21 extends to the first bevel gear 22 inside the column, the outer wall of the first bevel gear 22 is meshed with a second bevel gear 24 fixed on the screw shaft 23, the outer wall of the screw shaft 23 is spirally driven with a screw nut 26 fixed on the third slider 25, and one end of the third slider 25 is provided with a second strip groove 27 along the height direction of the column.
[0028] A second bidirectional cylinder 28 is detachably installed at the center of the bottom end of the third slider 25, and the piston rods at both ends of the second bidirectional cylinder 28 extend to the fourth slider 29. A fourth motor 30 is fixedly installed at one end of the fourth slider 29, and the output shaft of the fourth motor 30 passes through the fourth slider 29 and extends to the cutting knife 31; wherein, the second bidirectional cylinder 28 maintains synchronous movement with the first bidirectional cylinder 7, the protruding portion of the fourth slider 29 is connected to a T-slot along the length direction of the third slider 25, and a third guide roller 32 rotatably connected to the column is provided below the cutting knife 31.
[0029] One end of the lead screw nut 26 is provided with a crossbeam 33 which is perpendicular to the third slider 25, and an upper gear plate 34 placed inside the frame is fixedly installed on one side of the crossbeam 33 away from one end of the lead screw nut 26, and one end of the upper gear plate 34 is meshed and transmitted with a lower gear plate 36 through a central gear 35, and the extended ends of the upper gear plate 34 and the lower gear plate 36 are respectively connected with an upper pressure roller 37 and a lower pressure roller 38, and the upper pressure roller 37 and the lower pressure roller 38 are connected with a third strip groove 39 along the height direction of the frame, and the upper pressure roller 37 and the lower pressure roller 38 are connected to the frame through a guide block. As the third motor 21 is started, the third slider 25 drives the cutting knife 31 to extend to the third guide roller 32 for cutting, and at the same time, the crossbeam 33 drives the upper pressure roller 37 and the lower pressure roller 38 to press or separate through the upper gear plate 34 and the lower gear plate 36.
[0030] The pressing and cutting mechanism 2 can limit and guide the aluminum foil, and the force cutting and winding point positions correspond to each other. At the same time, the position of the cutting knife 31 can be adjusted according to the cutting requirements to adjust the cutting width. At the same time, the winding mechanism 3 can adjust the winding according to different cutting widths. By starting the third motor 21 in the pressing and cutting mechanism 2, the cutting knife 31 is moved downward to the cutting position of the third guide roller 32 through mechanical transmission. At the same time, the upper pressing roller 37 and the lower pressing roller 38 can be moved towards the center, thereby realizing the pressing and fitting of the aluminum foil during the cutting operation, preventing position deviation during the cutting operation, improving the cutting accuracy, and the transmission parts have strong linkage and high wedging, which ensures the integration of the pressing and cutting actions and improves product quality.
[0031] After the third motor 21 is started, it can first transmit power to the first bevel gear 22 and make it rotate. Since the second bevel gear 24 is meshed with the first bevel gear 22 for transmission and the two are kept vertically arranged, the horizontal rotation force can be converted into the vertical rotation force. Then the second bevel gear 24 drives the screw shaft 23 to rotate. With the help of the spiral transmission, the crossbeam 33 on the screw nut 26 and the third slider 25 are synchronously moved in the X-axis and Y-axis directions on the horizontal plane. During the moving work, the third slider 25 can drive the cutting knife 31 to move to the third guide roller 32. Under the action of the fourth motor 30, the corresponding material cutting work is performed, and in cooperation with the third The two bidirectional cylinders 28 can perform cutting work of different widths, so as to cut the actually required cutting width. At the same time, when the crossbeam 33 moves downward, it can drive the upper gear plate 34 to move downward, and can also drive the upper pressure roller 37 to move downward together. The upper gear plate 34 can connect the lower gear plate 36 and the lower pressure roller 38 to move upward synchronously through the meshing transmission of the central gear 35. In this way, the upper pressure roller 37 and the lower pressure roller 38 can better realize the center pressing work of the aluminum foil material, thereby preventing the material from being offset during the cutting operation and ensuring the cutting accuracy. Conversely, when the third slider 25 drives the cutting mechanism to move upward, the upper pressure roller 37 and the lower pressure roller 38 will also perform corresponding separation work.
[0032] The extended ends of the upper gear plate 34 and the lower gear plate 36 are correspondingly connected with an upper pressure roller 37 and a lower pressure roller 38. The upper pressure roller 37 and the lower pressure roller 38 are connected with a third strip groove 39 along the height direction of the frame. The setting of the third strip groove 39 on the frame can ensure the stability of the movement of the upper pressure roller 37 and the lower pressure roller 38 when moving, and can effectively prevent the position from deviating. In addition, it also provides corresponding activity space for the transmission parts during movement.
[0033] The working principle of the pressing and cutting mechanism 2 is essentially to press and fit the aluminum foil material while performing the cutting operation. This can effectively ensure the accuracy of the aluminum foil material cutting operation and avoid reducing the cutting accuracy. Moreover, by starting the power source of the third motor 21, mechanical transmission at multiple positions can be achieved, thereby ensuring the consistency of cutting and pressing work and improving cutting accuracy and product quality. Example
[0034] Reference Manual Attached Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 5 Limiting rings 40 are fixedly installed at both ends of the telescopic rod 6, and a winding cavity placed on the telescopic rod 6 is provided between the limiting rings 40. The output shaft of the first motor 4 is connected to the winding wheel 5. The first motor 4 can rotate together with the winding wheel 5 and realize the corresponding winding work. At the same time, the telescopic rod 6 is movably connected to the winding wheel 5. The telescopic rod 6 not only gives a certain supporting force to the first bidirectional cylinder 7, but also can drive it to rotate normally, thus avoiding the interference between the transmission parts during the movement work.
[0035] The telescopic rods 6 are connected by the first bidirectional cylinder 7. As the first bidirectional cylinder 7 is started, the winding area on the winding wheel 5 is telescopically adjusted. When the winding area on the winding wheel 5 is telescopically adjusted by the first bidirectional cylinder 7, its movement process is correspondingly connected with the cutting mechanism of the second bidirectional cylinder 28, so that the aluminum foil materials of different widths can be synchronously wound after cutting, and the limiting ring 40 on the telescopic rod 6 can play a good protective limiting role for the aluminum foil material, preventing the aluminum foil material from peeling off due to a large winding area.
[0036] With the help of the winding structure 3 and the cutting structure, the corresponding winding work is carried out, mainly through the synchronous movement of the telescopic rod 6 connected to the first two-way cylinder 7 and the cutting knife 31 connected to the second two-way cylinder 28. The whole can realize cutting and winding of various widths, and the overall equipment is low in cost and simple in principle. At the same time, the winding mechanism 3 starts the first two-way cylinder 7, so that the telescopic rod 6 at both ends can be telescopically adjusted, so that the winding area and cutting width on the winding wheel 5 can be adaptively changed. In addition, the first two-way cylinder 7 is connected by a transmission at both ends, which can better provide multiple winding position points, thereby effectively realizing multi-point winding work, improving work efficiency and reducing production costs.
