[0002] Aluminum foil is a hot stamping material that is directly rolled into thin sheets with metal aluminum. It is widely used in food, beverages, cigarettes, medicines, and household daily necessities. In recent years, as society pays more and more attention to environmental issues, the use of recyclable packaging materials to replace plastic bags has become a trend. Due to the low cost of aluminum foil and its convenient recycling, it has increasingly shown its unique superior performance in the packaging industry, especially in the food packaging industry. In addition, as an industrial metal raw material with a large amount of aluminum foil, some waste will be generated during the processing and production of aluminum foil products. In the face of large amounts of aluminum foil scraps, it is necessary to use equipment to crush them and then recycle them. The recycling and reuse of waste aluminum foil not only avoids environmental pollution, but also has huge economic benefits. Therefore, the recycling and reuse of aluminum foil is a cause that benefits the country and the people. It is necessary to use a dedicated aluminum foil crushing device to crush and reuse the aluminum foil waste. However, most of the existing aluminum foil crushing devices have a low degree of qualified crushing of aluminum foil waste, resulting in low crushing efficiency and high energy consumption.

DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0036] The following is a further description of the waste aluminum foil recycling device of the utility model in conjunction with the accompanying drawings and specific embodiments: Figure 1 and 5 As shown, this embodiment includes a frame 8, a feeding conveyor 1, an extrusion device 3, a cross-cutting device 4 and a longitudinal cutting device, wherein a feeding conveyor 1 is provided at the hopper on the upper side of the frame 8, an extrusion device 3 is provided at the material discharge port of the hopper, a cross-cutting device 4 is provided at the material discharge port of the extrusion device 3, and a longitudinal cutting device is provided at the material discharge port of the cross-cutting device 4, wherein the cross-cutting device 4 includes a motor 4-2, a cam rotating disk 4-1, a push rod 4-3, a spring 4-4, a push rod positioning sleeve 4-5, a moving cutter seat 4-6, a moving cutter 4-7, a static cutter The knife seat 4-8 and the static cutter 4-10, the motor 4-2 is fixed inside the frame 8, the output shaft is connected to one side of the push rod 4-3 through the cam turntable 4-1, the middle part of the push rod 4-3 is sleeved in the push rod positioning sleeve 4-5, a spring 4-4 ​​is arranged between the push rod 4-3 and the push rod positioning sleeve 4-5, a moving cutter seat 4-6 is arranged on the other side of the push rod 4-3, a moving cutter 4-7 is arranged on the moving cutter seat 4-6, and a static cutter 4-10 is arranged on the static cutter seat 4-8, and the moving cutter 4-7 and the static cutter 4-10 are arranged relatively. The static cutter seat 4-8 can be connected to the static cutter 4-10 through a buffer plate 4-9, which can slow down the excessive push of the moving cutter 4-7 on it. The blade of the static cutter 4-10 is provided with a V-shaped groove 4-11.

[0037] In addition, the static cutting knife seat 4-8, the static cutting knife 4-10 and the V-shaped groove 4-11 at the blade of the static cutting knife 4-10 can be replaced by a separate static cutting plate 4-8', on which a V-shaped groove 4-11 is provided corresponding to the blade of the dynamic cutting knife 4-7.

[0038] The feeding conveyor 1 can transport the aluminum foil from a low place to the feeding funnel 2 at a high place. The extrusion device 3 below the feeding funnel 2 can squeeze and compact the aluminum foil, and then it falls into the cross-cutting device 4 below. A cam turntable 4-1 is provided on the output shaft of the motor 4-2 in the cross-cutting device 4. When the two rotate, the cam turntable 4-1 can achieve a certain amplitude of periodic pushing on the moving cutter seat 4-6, so that the moving cutter 4-7 on the moving cutter seat 4-6 can reciprocate and hit the static cutter 4-10 or the static cutting plate 4-8'.

[0039] The push rod 4-3 in the cross-cutting device 4 is sleeved and slidable in the push rod positioning sleeve 4-5, and a reset spring 4-4 ​​is provided between one end of the push rod 4-3 and the push rod positioning sleeve 4-5. Since the cam turntable 4-1 realizes different degrees of periodic pushing of the push rod 4-3, the movable cutter seat 4-6 at the other end of the push rod 4-3 realizes periodic reciprocating movement under the action of periodic pushing and the rebound reset force of the spring 4-4, so that the blade of the movable cutter 4-7 hits the V-shaped groove 4-11 at the blade of the static cutter 4-10 on the static cutter seat 4-8, or hits the static cutting plate 4-8' with the V-shaped groove 4-11.

[0040] The movable cutter 4-7 can push, stretch and cut the aluminum foil paper that has stopped at the V-shaped groove 4-11 of the blade of the static cutter 4-10. When cutting, the aluminum foil paper at the V-shaped groove 4-11 of the blade of the static cutter 4-10 slowly slides into the V-shaped groove 4-11 under the push of the movable cutter 4-7, and the length of the aluminum foil paper here will inevitably be slightly elongated. Since the aluminum foil paper at the blades of the upper and lower adjacent static cutters 4-10 also needs to be pushed into the V-shaped groove 4-11 and elongated, multiple V-shaped grooves 4-11 are formed. The aluminum foil inside has no time to stretch, so it is pushed and torn by the passive cutter 4-7 while being cut. When the cam turntable 4-1 is not pushing the push rod 4-3, the dynamic cutter 4-7 is rebounded by the spring 4-4 ​​and moves away from the blade of the static cutter 4-10. At this time, the cut aluminum foil strip can be cut twice or multiple times during the descent process by adjusting the pushing frequency of the dynamic cutter 4-7, so as to become a thinner narrow strip, and finally falls onto the main conveyor belt 5 below, and is sent to the compacting conveyor belt 6 to wait for vertical cutting.

[0041] Alternatively, the V-shaped groove 4-11 can also be replaced by a double-layer static cutter 4-10 with a blade, which can also achieve a similar function. The common point of the two is that the aluminum foil at multiple static cutters 4-10 does not have time to be stretched and lengthened, resulting in the aluminum foil being cut or cracked after being pushed by the passive cutter 4-7. In addition, the static cutter 4-10 can be omitted, and the static cutter seat 4-8 can be replaced by a static cutting plate 4-8', and the static cutting plate 4-8' is provided with a V-shaped groove 4-11, which can also produce the same contact effect as the V-shaped groove 4-11 on the blade of the static cutter 4-10.

[0042] The compacting conveyor belt 6 contains a plurality of spaced compacting conveyor belts 6 wrapped around the compacting conveyor belt driving roller 6-1, with gaps 5-3 between them, and mainly transports aluminum foil strips and sends them to the bottom of the compacting conveyor belt 6. The aluminum foil strips are compacted under the joint action of the main conveyor belt 5 and the compacting conveyor belt 6 and wait for the rotating cutting knife group 7 to cut them longitudinally. Finally, the aluminum foil strips that have been cut transversely will be cut into blocks, thereby realizing the crushing of the aluminum foil. By adjusting the density of the gaps 5-3, aluminum foil sheets with different crushing degrees can be obtained.

[0043] like Figure 2 As shown, the extrusion device 3 contains a motor 4-2, a speed reducer, a dynamic extrusion roller 3-3 and a static extrusion roller 3-5. The upper surfaces of the dynamic extrusion roller 3-3 and the static extrusion roller 3-5 are provided with extrusion teeth 3-4, which can prevent the aluminum foil from falling too fast and not being cut in place by the cross-cutting device 4, or prevent the aluminum foil with a slightly larger size and a slightly thicker feeding amount from being difficult to be transported downward. The motor 4-2 drives the dynamic extrusion roller 3-3 through the speed reducer, and the dynamic extrusion roller 3-3 drives the static extrusion roller 3-5 through the gears 3-6 that mesh with each other. One of the extrusion rollers in the extrusion device 3 is connected to its power device 5-1 through a belt 3-1 and a pulley 3-2. The extrusion roller is called the dynamic extrusion roller 3-3, and the extrusion roller opposite to it is called the static extrusion roller 3-5. The outer walls of both are evenly distributed with extrusion teeth 3-4 in an annular manner. The extrusion teeth 3-4 above the two mesh with each other to achieve the same speed rotation. In addition, mutually meshing gears 3-6 of the same diameter can be set on the rotating shafts of the dynamic extrusion roller 3-3 and the static extrusion roller 3-5 to transmit the same speed to each other, so that the extrusion tooth grooves 3-4 do not need to be tightly engaged. Both situations can play the role of moderately clamping the aluminum foil and transmitting it downward at a constant speed, not only can the slightly larger size and slightly thicker feed be initially extruded to become solid and thin, but even the initial tearing of part of the extrusion can be achieved to adapt to the occasions of slightly larger size and slightly thicker feed, and the pushing frequency of the dynamic cutter 4-7 can be adjusted to achieve secondary or multiple pushing cutting of the aluminum foil with slightly larger size and slightly thicker feed, thereby turning it into thinner and more dispersed narrow strips, and finally falling onto the main conveyor belt 5 below, and being sent to the compacting conveyor belt 6 to wait for cutting in the vertical direction.

[0044] like Figure 9-12 As shown, the longitudinal cutting device contains a main conveyor belt 5, a compression conveyor belt 6 and a rotary cutter group 7, and the three are driven by independent power devices 5-1 respectively. A compression conveyor belt 6 is provided above the upper conveying surface of the main conveyor belt 5. The rotary cutter group 7 contains telescopic legs 7-4, a horizontal tool holder 7-1, a driving shaft 7-2 and a plurality of rotary cutters 7-3, wherein the telescopic legs 7-4 are located on both sides of the traveling direction of the main conveyor belt 5 and the compression conveyor belt 6, a horizontal tool holder 7-1 is provided above the telescopic legs 7-4 and passes through between the upper and lower conveying surfaces of the main conveyor belt 5, a driving shaft 7-2 is provided on the horizontal tool holder 7-1, a plurality of rotary cutters 7-3 are arranged in parallel and then sleeved on the driving shaft 7-2, a plurality of slits 5-3 are provided on the conveying surface of the main conveyor belt 5 and the compression conveyor belt 6 respectively, and a rotary cutter 7-3 is respectively embedded in the slits 5-3. The main conveyor belt 5 and the compression conveyor belt 6 clamp the aluminum foil strip together and convey it to the rotary cutter 7-3 for cutting. The rotary cutter group 7 contains a plurality of spaced rotary cutters 7-3 sleeved on the drive shaft 7-2 of the rotary cutter 7-3. After debugging, the plurality of spaced rotary cutters 7-3 can be inserted from the lower part of the upper half of the main conveyor belt 5 and extend out of a part of the upper surface of the main conveyor belt 5. Each rotary cutter 7-3 is embedded in the gap 5-3 between the spaced compression conveyor belt 6 and the main conveyor belt 5. The horizontal knife frame 7-1 is provided with a plurality of rows of drive shafts 7-2, and the drive shafts 7-2 are provided with a plurality of rows of rotary cutters 7-3 at intervals. If the first row of cutters does not completely cut the horizontal aluminum foil strip, the second row of cutters can continue to cut, and the diameter of the second row of cutters can be set larger.

[0045] The horizontal knife holder 7-1 in the rotary cutter group 7 is fixed by a telescopic leg 7-4 provided on its lower surface. A telescopic sleeve portion is provided in the middle of the telescopic leg 7-4, where the height of the telescopic leg 7-4 is adjusted and fixed by the tightening degree of the manual bolt.

[0046] The rotation direction of the upper part of the rotary cutter 7-3 is set opposite to the direction in which the waste aluminum foil paper travels on the main conveyor belt 5, so as to ensure that the waste aluminum foil paper has a greater probability of being cut off, and will not be carried out of the main conveyor belt 5 without being cut off when in the same direction.

[0047] The disconnected part of the telescopic leg 7-4 is connected by a sleeve, and a manual bolt is provided on the outer wall of the sleeve. The telescopic leg 7-4 can adjust the optimal height of the rotary cutter 7-3 to enable reliable cutting. The power device 5-1 involved in this scheme can be designed as an electric motor 4-2 and a reducer, and the output shaft of the electric motor 4-2 is connected to the input shaft of the reducer. The electric motor 4-2 can also be replaced by an internal combustion engine.

[0048] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
