Description

Technical Field

[0001] The invention relates to the technical field of coil cutting and stripping, in particular to a device for cutting and stripping waste aluminum foil coils. Background Art

[0002] In aluminum foil production and processing enterprises, there are often tail materials wound on the reel. This tail material is generally waste that does not meet the technical requirements. Before these waste materials are reused, the waste materials wound on the reel must be removed so that the reel can be taken out for continued use in production.

[0003] At present, there are three ways to remove waste from the reel: manual, heavy rewinding device and cutting and stripping machine.

[0004] During manual operation, the waste is cut with a knife to a certain thickness, and then the cut waste is pushed away by hand, and then the cutting and pushing operations are repeated until the roll is separated from the aluminum foil. This method can easily cause accidents in which the hands are scratched, and the cutting and stripping efficiency of this method is very low.

[0005] The rewinding equipment rewinds the waste material onto the expansion shaft on the machine train to remove the roll. This method is more efficient, but the investment and production costs are high.

[0006] The cutting and stripping machine removes the roll by automatic cutting and stripping. The patent with publication number CN103128549B discloses an automatic cutting and stripping machine for aluminum foil coil waste, including a machine base, a clamping mechanism for clamping aluminum foil coils, an automatic cutting and stripping mechanism for cutting and stripping aluminum foil coils, an automatic feeding mechanism for cutting and stripping, an automatic feeding mechanism for transporting the aluminum foil coils to the clamping station, and a lifting mechanism. The aluminum foil coil is transported to the clamping station by the automatic feeding mechanism, the sleeve with the waste is clamped by the conical clamping head, the cutting and stripping mechanism is driven to move horizontally by the automatic feeding mechanism for cutting and stripping, and the cutting and stripping assembly is driven to move up and down by the lifting mechanism. When the cutting and stripping assembly approaches the surface of the waste, release the "quick descent" button, and then press the automatic cutting button to continue automatic cutting and stripping. When the waste is cut and stripped to a position close to the sleeve, the mechanical limit switch detects the tool and forces the cutting and stripping work to be completed.

[0007] However, the above automatic cutting and stripping machine has the disadvantages of complex structure and high cost. In addition, when the cutting and stripping assembly is cutting above the aluminum foil coil waste, the cut aluminum foil may fall off the roll under the action of gravity and cannot remain intact with the roll, resulting in inconvenience in collection.

[0021] In order to make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0022] Please refer to Figures 1 to 16 , the embodiment of the present application provides an aluminum foil coil waste cutting and stripping device, including: a frame 1, a moving trolley 2, a cutting mechanism 3, and a stripping part 4.

[0023] Among them, the moving trolley 2 can move linearly along the frame 1, and the moving trolley 2 has a supporting part 21 for supporting the aluminum foil coil waste 6; when the aluminum foil coil waste 6 is placed on the moving trolley, its bottom contacts the supporting part 21.

[0024] The cutting mechanism 3 includes a cutting knife 31, the upper end of the cutting knife 31 is higher than the supporting part 21, and the cutting knife 31 is used to cut the bottom of the aluminum foil coil waste 6 conveyed by the moving trolley 2, so as to form a cutting seam at the bottom of the aluminum foil coil waste 6. When the moving trolley 2 carries the aluminum foil coil waste 6 past the cutting knife 31, the part of the upper end of the cutting knife 31 that is higher than the supporting part 21 will contact the aluminum foil coil waste 6, thereby cutting the aluminum foil coil waste 6.

[0025] The stripping part 4 is fixedly connected to the frame 1, and the stripping part 4 is used to contact and cooperate with the aluminum foil coil waste 6 to expand the cutting seam when the aluminum foil coil waste 6 passes by. The stripping part 4 is arranged adjacent to the cutting knife 31. After the cutting knife 31 cuts a cutting seam in the aluminum foil coil waste 6, the stripping part 4 immediately expands the cutting seam.

[0026] Compared with the prior art cutting and stripping machine, the aluminum foil coil waste cutting and stripping device provided in this embodiment adopts the method of placing the cutting mechanism 3 at the bottom, and the cutting knife 31 cuts the aluminum foil coil waste 6 on the moving trolley 2 from bottom to top. Since the lower part of the aluminum foil is supported by the moving trolley 2 and the upper part of the aluminum foil is attached to the reel 61, the aluminum foil will not be separated from the reel 61 due to gravity, and the aluminum foil after cutting and stripping remains integrated with the reel 61, which can facilitate the collection of the aluminum foil.

[0027] For the aluminum foil coil waste 6 whose thickness to be cut is greater than the length of the cutting knife 31 extending out of the support part 21, it is impossible to complete the cutting in one go and multiple cuttings are required. During the cutting process, the stripping member 4 expands the cutting seam outward to reduce the distance between the center of the roll 61 and the bottom of the aluminum foil coil waste 6. By utilizing the effect of gravity, the aluminum foil coil waste 6 naturally drops after the cutting is completed, making it easier for the cutting knife 31 to cut the aluminum foil coil waste 6 again.

[0028] The aluminum foil coil waste cutting and stripping device provided in this embodiment does not require automated equipment to drive the cutting mechanism 3 to move in the horizontal and vertical directions. It only needs to drive the mobile trolley 2 to move linearly back and forth to achieve the cutting and stripping of the aluminum foil coil waste 6. It has a simple structure and low cost.

[0029] In some embodiments, Figures 1 to 4 As shown, in order to facilitate the upper end of the cutting blade 31 to extend out of the support portion 21 , a long opening 211 is provided on the support portion 21 , and the upper end of the cutting blade 31 extends out of the long opening 211 .

[0030] The stripping piece 4 is located above the support portion 21, and the top of the stripping piece 4 is lower than the top of the cutting knife 31, which can be easily contacted with the cutting seam of the aluminum foil coil waste 6 on the support portion 21. In order to facilitate the installation and fixation of the stripping piece 4, a support piece 41 is fixed to the bottom of the stripping piece 4, and the lower end of the support piece 41 passes through the long strip opening 211 and is fixedly connected to the frame 1.

[0031] In some embodiments, Figures 1 to 4As shown, the support portion 21 is a planar structure. The support portion 21 is the bottom surface of the mobile trolley 2. The mobile trolley 2 of this design has a simple shape and low production and processing costs. Since the distance between the top of the stripping member 4 and the support portion 21 is limited, after the aluminum foil coil waste 6 is cut once or multiple times, the portion of the aluminum foil coil waste 6 that is cut and stripped will be piled on the support portion 21, resulting in a larger distance between the top of the cutting seam and the support portion 21, and the stripping member 4 has a poor effect of expanding the cutting seam, and the cutting knife 31 cannot efficiently cut the position above the cutting seam. At this time, since the portion of the aluminum foil coil waste 6 that is cut and stripped has a certain flexibility, the cutting seam can be expanded manually, and the aluminum foil coil waste 6 can be stripped, so that the distance between the top of the cutting seam and the support portion 21 becomes smaller, thereby improving the cutting efficiency of the cutting knife 31 on the aluminum foil coil waste 6.

[0032] As a parallel embodiment, Figures 6 to 15 As shown, the above-mentioned characteristic support portion 21 can also be set as a raised structure, and the raised structure can specifically be an inverted V-shaped raised structure. The long strip opening 211 is located at the top of the support portion 21, and the top of the support portion 21 is at a certain distance from the bottom surface of the moving trolley 2. A accommodating space 212 that can accommodate the peeled-off part of the aluminum foil coil waste 6 is formed between the support portion 21 and the bottom of the trolley 2.

[0033] After the aluminum foil coil waste 6 is processed once, the two ends of the bottom of the cutting seam will extend to both sides of the long strip opening 211 through the outward expansion of the stripping piece 4, and the cut and stripped part of the aluminum foil coil waste 6 will enter the accommodating space 212, so that the height of the aluminum foil coil waste 6 is reduced.

[0034] The cut seam of the aluminum foil coil waste 6 should not be separated from the stripping member 4, so as to prevent the aluminum foil coil waste 6 from falling due to gravity so that the top of the cut seam is completely in contact with the top of the support part 21, resulting in the stripping member 4 blocking the aluminum foil coil waste 6 from passing through when the aluminum foil coil waste 6 is moved and cut again. If the above situation occurs, the aluminum foil coil waste 6 needs to be lifted so that the top of the cut seam of the aluminum foil coil waste 6 exceeds the top of the stripping member 4, so that the aluminum foil coil waste 6 can contact the cutting knife 31 after passing through the stripping member 4.

[0035] In some embodiments, in order to facilitate driving the cutting blade 31 to rotate and cut the aluminum foil coil waste 6, Figure 5 As shown, the cutting mechanism 3 includes a rotating shaft 32, a rotating power source 33, a cutting bracket 34 and a transmission assembly 35. The cutting bracket 34 is fixedly connected to the frame 1, the rotating shaft 32 is rotatably connected to the cutting bracket 34, the cutting knife 31 is fixedly mounted on the rotating shaft 32, and the rotating power source 33 is transmission-connected to the rotating shaft 32 through the transmission assembly 35.

[0036] Specifically, a bearing is installed on the cutting bracket 34, and the rotating shaft 32 is rotatably connected to the cutting bracket 34 through the bearing.

[0037] The rotary power source 33 is selected as an electric motor, and it can also be a pneumatic motor or a hydraulic motor. The rotary power source 33 is fixedly installed on the frame 1.

[0038] The transmission assembly 35 is selected as a belt transmission assembly in the prior art, including a driving pulley, a driven pulley and a transmission belt. The driving pulley is installed on the rotor of the rotary power source 33, the driven pulley is installed on the rotating shaft 32, and the driving pulley and the driven pulley are connected by the transmission belt for transmission. A protective shell is installed on the periphery of the transmission assembly 35, and the protective shell surrounds the transmission assembly 35 to protect the transmission assembly 35. In other embodiments, the transmission assembly 35 can also be selected as a chain transmission assembly in the prior art.

[0039] In some embodiments, to facilitate the outer expansion of the cutting seam by the peeling member 4, as Figure 2 and Figure 7 shown, the peeling member 4 is provided with an outer expansion surface 42 in a V shape, and the outer expansion surface 42 is used for outer expanding the cutting seam.

[0040] In this embodiment, the peeling member 4 is provided in a rhombus shape and has two outer expansion surfaces 42 in a V shape. When the moving trolley 2 drives the aluminum foil coil waste 6 to move reciprocally in a straight line, it can contact the two outer expansion surfaces 42 respectively. In some other embodiments, the peeling member 4 can also be provided in a triangular shape or other shapes with a V-shaped surface, and has an outer expansion surface 42 in a V shape with the tip facing the cutting knife 31. After the cutting knife 31 cuts the aluminum foil coil waste 6 to form a cutting seam, the outer expansion surface 42 directly contacts the cutting seam to expand the cutting seam. The description of the shape of the above outer expansion surface 42 is determined from a top view perspective.

[0041] In some embodiments, as Figures 1 to 4 , Figures 6 to 14 shown, to facilitate the stable movement of the moving trolley 2 driving the aluminum foil coil waste 6 and avoid the aluminum foil coil waste 6 being unable to move forward smoothly for cutting and peeling due to resistance when contacting the cutting knife 31 or the peeling member 4, a limiting member 22 is fixedly installed on the moving trolley 2.

[0042] The limiting member 22 can abut against the end of the aluminum foil coil waste 6, thereby restricting the axial movement of the aluminum foil coil waste 6 and enabling the moving trolley 2 to drive the aluminum foil coil waste 6 to move stably.

[0043] By providing the limiting member 22, it is possible to avoid the situation where the operator needs to push the aluminum foil coil waste 6 to move together while pushing the moving trolley 2, and it is convenient to efficiently cut and peel the aluminum foil coil waste 6.

[0044] In this embodiment, the number of the limiting members 22 is set to two. The two limiting members 22 are respectively close to both ends of the moving trolley 2. The limiting member 22 has a round rod-shaped structure or can also have a flat plate-shaped structure. In some other embodiments, the number of the limiting members 22 can also be set to one.

[0045] In some embodiments, to facilitate the linear movement of the moving trolley 2 along the frame 1, as Figures 1 to 4 , Figures 6 to 14 shown, a linear track 11 is fixedly arranged on the frame 1. The moving trolley 2 includes traveling wheels 23 installed at its bottom, and the traveling wheels 23 are in rolling connection with the linear track 11.

[0046] Furthermore, to prevent the moving trolley 2 from disengaging from the linear track 11 and to avoid the cutting knife 31 from contacting the two ends of the long strip opening 211, intercepting rods 111 are fixedly arranged at both ends of the linear track 11. The intercepting rods 111 can contact the moving trolley 2 to limit the moving range of the moving trolley.

[0047] In some embodiments, to prevent the waste aluminum foil coil 6 from radially moving on the moving trolley 2, resulting in the cutting knife 31 being unable to accurately cut a linear cutting seam, as Figures 10 to 14 shown, a positioning mechanism 5 is further provided. The positioning mechanism 5 is located at one end of the moving trolley 2. A limiting member 22 can or cannot be arranged at the other end of the moving trolley 2.

[0048] Specifically, as Figures 14 to 16 shown, the positioning mechanism 5 includes a fixed frame 51, guide rails 52, a lifting seat 53, a guide sleeve 54, a hollow tube 55, a nut seat 56, a screw rod 57, a moving seat 58 and a scissor assembly 59. The fixed frame 51 is fixedly connected with the moving trolley 2. The guide rails 52 are vertically arranged in two numbers and are fixedly connected with the fixed frame 51. The lifting seat 53 is fixed on the sliding seat of the guide rail 52. A guide sleeve 54 is installed on the lifting seat 53. The hollow tube 55 is slidably connected with the guide sleeve 54. The hollow tube 55 is a non-circular tube, specifically a rectangular tube. The guide sleeve 54 is adapted to the hollow tube 55 to limit the rotation of the hollow tube 55, so that the hollow tube 55 can only move linearly.

[0049] The nut seat 56 is fixedly connected to the hollow tube 55. The screw rod 57 is threadedly connected to the nut seat 56 and passes through the hollow tube 55. Two moving seats 58 are rotatably mounted on the screw rod 57. Bearings are installed in the moving seats 58. The screw rod 57 is fixedly connected to the inner ring of the bearing. The part of the screw rod 57 connected to the bearing is not provided with external threads. One of the moving seats 58 is away from the operating end of the screw rod 57, and the other moving seat 58 is close to the operating end of the screw rod 57. The operating end of the screw rod 57 is the end where the screw rod 57 is manually rotated, and the other end of the screw rod 57 is the insertion end for inserting into the reel 61. A rotating handle is fixed on the operating end of the screw rod 57. The screw rod 57 is coaxially arranged with the hollow tube 55. The screw rod 57 and the hollow tube 55 are located directly above the long slot 211.

[0050] At least two scissor assemblies 59 are provided on the moving seat 58 away from the operating end of the screw rod 57, and the scissor assemblies 59 are circumferentially distributed along the center of the screw rod 57; at least one downward scissor assembly 59 is provided on the moving seat 58 close to the operating end of the screw rod 57. In this embodiment, four scissor assemblies 59 are provided on the moving seat 58 away from the operating end of the screw rod 57, and two scissor assemblies 59 are provided on the moving seat 58 close to the operating end of the screw rod 57. In other embodiments, two, three, five or six scissor assemblies 59 can also be provided on the moving seat 58 away from the operating end of the screw rod 57, and one, three, four, five or six scissor assemblies 59 can be provided on the moving seat 58 close to the operating end of the screw rod 57.

[0051] The scissor assembly 59 includes a scissor frame 591 and a movable plate 592. The first end of the scissor frame 591 is hinged to the moving seat 58, the second end of the scissor frame 591 is hinged to the hollow tube 55, the third end of the scissor frame 591 is hinged to the movable plate 592, and the fourth end of the scissor frame 591 is slidably connected to the movable plate 592. The length direction of the movable plate 592 is parallel to the length direction of the hollow tube 55. By rotating the screw rod 57, under the action of the nut seat 56, the screw rod 57 rotates and axially moves at the same time, driving the moving seat 58 to move. The moving seat 58 drives the scissor frame 591 to expand or contract, so that the movable plate 592 moves away from or close to the hollow tube 55. Since the scissor assembly 59 restricts the rotation of the moving seat 58 and bearings are installed inside the moving seat 58, the screw rod 57 can drive the moving seat 58 to move linearly.

[0052] An activity opening 552 for the scissor assembly 59 to move is provided on the hollow tube 55, which is convenient for the connection between the moving seat 58 close to the operating end of the screw rod 57 and the first end of the scissor frame 591.

[0053] The fixed frame 51 has a blocking section 511 for contact and cooperation with the movable plate 592 of the scissor assembly 59 near the operating end of the screw 57. The blocking section 511 is located at the lower part of the fixed frame 51. When the movable plate 592 of the scissor assembly 59 contacts the blocking section 511, the height of the top end of the cutting knife 31 is not higher than the height of the bottom end of the reel 61 of the aluminum foil coil waste 6. Preferably, the distance between the top end of the cutting knife 31 and the bottom end of the reel 61 is less than 1 cm. This can avoid the cutting knife 31 contacting the reel 61 and at the same time make the thickness of the remaining unpeeled aluminum foil smaller, facilitating rapid manual peeling.

[0054] Since each scissor assembly 59 moves synchronously under the drive of the screw 57, when the scissor assembly 59 on the moving seat 58 far from the operating end of the screw 57 unfolds and clamps the inner wall of the reel 61, the distances from each movable plate 592 to the center of the reel 61 are the same. Therefore, if the height of the blocking section 511 is set to be the same as the height of the top end of the cutting knife 31, when the blocking section 511 contacts the movable plate 592 of the downward scissor assembly 59 near the operating end of the screw 57, the top end of the cutting knife 31 will also complete the cutting of the bottom end of the reel 61. Therefore, the sum of the height value of the top end of the cutting knife 31 and the wall thickness value of the reel 61 should be less than and close to the height value of the blocking section 511.

[0055] The positioning mechanism 5 provided in this embodiment can clamp reels 61 with different diameters and adapt to different sizes and types of aluminum foil coils, with high flexibility in use. Moreover, the positioning mechanism 5 is a physical isolation barrier. Compared with the emergency stop system of the existing peeling machine that relies on electrical feedback, it can improve safety and avoid safety accidents when the electrical feedback fails.

[0056] Based on the positioning mechanism 5 of the above embodiment, in a preferred embodiment, to facilitate pushing the aluminum foil coil waste 6 to move together with the trolley 2 through the positioning mechanism 5, as Figure 15 and Figure 16 shown, the positioning mechanism 5 is further provided with a limiting mechanism 50.

[0057] Specifically, the limiting mechanism 50 includes a plug rod 501, an elastic member 502, a pull handle 503, an upper baffle 504, a lower baffle 505, and a fixing piece 506. Both the upper baffle 504 and the lower baffle 505 are fixedly connected to the lifting seat 53. The plug rod 501 is inserted into the upper baffle 504, the lower baffle 505, and the guide sleeve 54. The elastic member 502 is sleeved on the plug rod 501. The fixing piece 506 is fixedly installed on the plug rod 501. The upper end of the elastic member 502 is connected to the upper baffle 504, and the lower end of the elastic member 502 is connected to the fixing piece 506. The fixing piece 506 is located above the lower baffle 505. A positioning hole 551 for plugging and cooperating with the plug rod 501 is formed on the hollow tube 55. When the plug rod 501 is inserted into and cooperates with the positioning hole 551, the movable plate 592 of the scissors assembly 59 near the operating end of the screw rod 57 is in a position where it can contact the intercepting surface 511.

[0058] The elastic member 502 is a spring. The elastic member 502 pushes the fixing piece 506 downward, so that the lower end of the plug rod 501 abuts against the upper end of the hollow tube 55. When the hollow tube 55 axially moves to a suitable position, the insertion end of the hollow tube 55 is inserted into the winding drum 61, and the positioning hole 551 moves to directly below the plug rod 501. Under the action of the elastic member 502 and the self-weight of the plug rod 501, the lower end of the plug rod 501 is inserted into the positioning hole 551, and the fixing piece 506 abuts against the lower baffle 505, thereby restricting the relative movement of the hollow tube 55 with respect to the moving trolley 2. After the scissors assembly 59 clamps the winding drum 61, under the action of the frictional force between the movable frame 591 and the winding drum 61, the aluminum foil coil waste 6 is moved by pushing the trolley 2.

[0059] To facilitate the stable movement of the aluminum foil coil waste 6 with the trolley 2, a push plate 553 is fixed on the hollow tube 55. In this way, even if the movable plate 592 of the scissors assembly 59 does not clamp the winding drum 61 tightly, there is still the push plate 553 that can abut against the winding drum 61, so that the aluminum foil coil waste 6 moves together with the trolley 2.
