Technical Field

[0001] This utility model relates to the field of aluminum foil tube processing, and more specifically, it relates to an aluminum foil tube production and cutting device. Background Technology

[0002] Aluminum foil is a thin sheet material made of aluminum, usually less than 0.2 mm thick. It is lightweight, flexible, corrosion resistant, and has good thermal and electrical conductivity. Aluminum foil tubes are usually composed of spiral-shaped steel wire inner ribs and aluminum foil paper attached to the outer wall of the inner ribs. The whole tube forms a corrugated structure and is soft in texture. It is commonly used as central air conditioning exhaust ducts, range hood ducts, etc.

[0003] A cutting device with a slitting mechanism is disclosed in patent CN219748164U, including a support mechanism; a slitting mechanism disposed on top of the support mechanism; a movable mounting mechanism disposed on top of the support mechanism; and an adjusting clamping mechanism disposed on top of the support mechanism. The support mechanism includes a fixed plate, with support seats fixedly sleeved at the four corners of the bottom of the fixed plate. The slitting mechanism includes a limiting plate, with a movable block movably sleeved on the outer wall of the limiting plate. The movable block is hollow inside, and a motor is fixedly installed on the left side of the inner wall of the movable block. A connecting rod is disposed on the right side of the motor. The right side of the movable block is fixedly connected to the limiting block through two limiting rods.

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] An aluminum foil tube production and cutting device, such as Figures 1-4 As shown, the device includes a base 1, a housing 2 fixedly connected to the base 1, a motor 3 fixedly connected to the housing 2, a sleeve 4 fixedly connected to the output shaft of the motor 3, and a cutting mechanism for cutting aluminum foil on the housing 2. The cutting mechanism includes a turntable 5 rotatably connected to the housing 2, several fixed blocks 6 fixedly connected to the turntable 5, a spring telescopic rod 7 fixedly connected to the fixed blocks 6, and a cutter 8 fixedly connected to the telescopic end of the spring telescopic rod 7. The sleeve 4 is provided with a driving assembly for driving the cutters 8 away from each other. The driving assembly includes a trigger rod 9 slidably connected to the sleeve 4, a positioning plate 10 rotatably connected to the trigger rod 9, and an electric push rod 11 fixedly connected to the positioning plate 10. The electric push rod 11 is fixedly connected to the inner wall of the housing 2. The turntable 5 is provided with a connector for driving the cutters 8 to rotate. The connector includes an extension ring 12 fixedly connected to the side of the turntable 5 away from the cutters 8, and several sliding plates 13 slidably connected to the inner wall of the extension ring 12. The several sliding plates 13 are all fixedly connected to the trigger rod 9.

[0020] like Figures 1-4As shown, when cutting the aluminum foil tube, the outer casing 2 is first inserted into the aluminum foil tube, and then the electric push rod 11 is activated to extend. The electric push rod 11 will drive the positioning plate 10 away from the sleeve 4 and drive the trigger rod 9 to slide on the sleeve 4. When the trigger rod 9 slides, the sliding plate 13 will also slide on the extension ring 12. Then the inclined surface of the trigger rod 9 will contact the cutter 8. As the trigger rod 9 continues to slide away from the sleeve 4, several cutters 8 will move away from each other and move closer to the inner wall of the aluminum foil tube to cut the aluminum foil tube. At this time, the spring telescopic rod 7 is in a compressed state, and since the aluminum foil tube will be subjected to multiple directions of pushing force at the same time, several cutters 8 can cut the aluminum foil tube at the same time, thereby avoiding the aluminum foil tube being cut due to one side being subjected to force. The aluminum foil tube is curled and deformed due to force. Then, the motor 3 is started, which drives the sleeve 4 to rotate. The sleeve 4 then drives the trigger rod 9 to rotate. Since the sliding rod 14 is fixedly connected to the trigger rod 9, it can drive the extension ring 12 and the turntable 5 to rotate. At this time, the cutter 8 will also rotate with the turntable 5 to cut the aluminum foil tube, thereby avoiding uneven cutting and improving the cutting quality. After the cutting is completed, the electric push rod 11 is started to retract and reset, driving the trigger rod 9 to move closer to the bottom of the sleeve 4 until the electric push rod 11 is fully reset. When the electric push rod 11 resets, the spring telescopic rod 7 will also reset, driving several cutters 8 to move closer to each other and reset. Then, the aluminum foil tube that has fallen onto the outer shell 2 can be removed.

[0021] like Figure 1 , Figure 2 , Figure 4 As shown, several sliding rods 14 are slidably connected to the outer shell 2. A positioning block 15 is fixedly connected to the end of the sliding rod 14 away from the trigger rod 9. A tension spring 16 is fixedly connected between the positioning block 15 and the outer shell 2. The tension spring 16 is sleeved on the sliding rod 14. A trigger ring 17 is fixedly connected to the trigger rod 9. The sliding rod 14 and the trigger ring 17 are in contact with each other. When the electric push rod 11 drives the trigger rod 9 away from the sleeve 4, the trigger ring 17 will contact the several sliding rods 14 and push the several sliding rods 14 away from each other. At this time, the tension spring 16 will deform and stretch, and the several positioning blocks 15 will contact the inner wall of the aluminum foil tube. The aluminum foil tube is positioned before cutting, so that it is not necessary to manually hold the aluminum foil tube or use external equipment to fix the aluminum foil tube. When the electric push rod 11 retracts and drives the trigger rod 9 to move towards the bottom side of the sleeve 4, the several sliding rods 14 will slide on the inclined surface of the trigger ring 17 and move closer to each other, releasing the restriction on the cut part of the aluminum foil tube. At this time, the cut-off excess part can be removed.

[0022] like Figures 1-2 As shown, a protective plate 18 is fixedly connected to the turntable 5. The protective plate 18 has a through hole 19 for the trigger rod 9 and the sliding plate 13 to pass through. The protective plate 18 can prevent the operator from directly contacting the cutter 8 when the shearing device is not in operation, thereby improving the safety of the device.

[0023] Working principle: When cutting aluminum foil tubes, the outer casing 2 is first inserted into the aluminum foil tube. Then, the electric push rod 11 is activated to extend. The electric push rod 11 will drive the positioning plate 10 away from the sleeve 4 and drive the trigger rod 9 to slide on the sleeve 4. Subsequently, the trigger ring 17 will contact several sliding rods 14 and push the sliding rods 14 away from each other. At this time, the tension spring 16 will deform and stretch, and several positioning blocks 15 will contact the inner wall of the aluminum foil tube, positioning the aluminum foil tube before cutting. Then, the inclined surface of the trigger rod 9 will contact the cutter 8. As the trigger rod 9 continues to slide away from the sleeve 4, the cutters 8 will move away from each other. The inner wall of the aluminum foil tube is brought close to and cut open. At this time, the spring telescopic rod 7 is in a compressed state. Since the aluminum foil tube will be subjected to multiple directions of pushing force at the same time, several cutters 8 can cut the aluminum foil tube at the same time. This avoids the aluminum foil tube from curling and deforming due to force on one side. Then, the motor 3 is started. The motor 3 will drive the sleeve 4 to rotate. The sleeve 4 will then drive the trigger rod 9 to rotate. Since the sliding rod 14 is fixedly connected to the trigger rod 9, it can drive the extension ring 12 and the turntable 5 to rotate. At this time, the cutter 8 will also follow the turntable 5 to cut the aluminum foil tube, thereby avoiding uneven cutting and improving cutting quality.

[0024] After cutting is completed, the electric push rod 11 is retracted and reset, which drives the trigger rod 9 to move closer to the bottom of the sleeve 4 until the electric push rod 11 is fully reset. When the electric push rod 11 is reset, the spring telescopic rod 7 will also be reset, which will drive several cutters 8 to move closer to each other and reset. Then several sliding rods 14 will slide on the inclined surface of the trigger ring 17 and move closer to each other, releasing the restriction on the cut part of the aluminum foil tube. At this time, the excess part can be removed.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
