Description

Technical Field

[0001] This invention relates to the field of aluminum rod production and processing technology, and in particular to a method and apparatus for polishing the end face of aluminum rods used in cigarette packaging. Background Technology

[0002] The shiny layer of paper inside cigarette packs is now made of aluminum, which should actually be called "aluminum foil." However, it's still commonly referred to as "tin foil." With the protection of tin foil, the flavor of chewing gum and cigarettes won't be affected by external stimuli and, more importantly, it won't spoil due to air and humidity, and the cigarettes won't turn yellow... thus extending their shelf life.

[0003] Before the aluminum rods used to manufacture aluminum films are turned, the end faces need to be ground.

[0004] Aluminum rod end face grinding machines are mainly manual or semi-automatic. In the manual mode, workers need to hold the aluminum rods to grind them, which is inefficient and dangerous for batch processing. The semi-automatic mode still requires manual fixing of the aluminum rods to the clamping mechanism, which improves efficiency, but the overall processing speed is limited. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a method and apparatus for polishing the end face of aluminum rods used in cigarette packaging, so as to solve the problems of low efficiency and inconvenient operation of current aluminum rod grinding machines.

[0006] To achieve the above objectives, the present invention provides a method and apparatus for polishing the end face of an aluminum rod used in cigarette packaging.

[0007] A polishing device for the end face of an aluminum rod in a cigarette box package includes a base. Both ends of one side of the upper part of the base are fixed with slides, and the slides are inclined. The lower ends of the two slides that are close to each other have push-out notches, and the other side of the slides is provided with push-out components.

[0008] Mounting plates are fixed at the middle positions of both sides of the upper part of the base, and a grinding wheel is rotatably mounted on one side of each mounting plate. A grinding motor that drives the grinding wheel is fixed on the other side of each mounting plate.

[0009] The base has a strip-shaped groove, and a movable block is slidably disposed in the strip-shaped groove. The base is provided with a drive component for driving the movable block to slide, and a movable seat is fixed on the upper part of the movable block. The movable seat is U-shaped, and through openings are opened on both sides of the movable seat. A material placement cylinder is rotatably disposed in each through opening. A material placement groove is coaxially opened on one end of the material placement cylinder near the slide rail, and a clamping mechanism is provided in each material placement groove. A slide tube is slidably inserted into the other end of the material placement cylinder. The slide tube is used to drive the internal clamping mechanism to clamp or release.

[0010] Each of the material feeding cylinders is fitted with a toothed ring at the end away from the slide rail. Two toothed racks are fixed on the upper part of the base, and when the movable seat moves to the position of the toothed racks, the two toothed rings engage with the two toothed racks respectively.

[0011] Furthermore, a guide rod is fixed at the upper part of the base between the two grinding wheels. The guide rod is divided into narrow sections at both ends and a wide section in the middle. When the movable seat slides, one end of each of the two slide tubes slides on the two side walls of the guide rod. A support rod is fixed at the bottom of the slide, and the lower end of the support rod is fixed to the base.

[0012] Furthermore, the ejection assembly includes two electric push rods. The lower end of the slide away from the ejection notch has a circular opening, and a mounting bracket is fixed at the circular opening on one side of the slide. The two electric push rods are respectively fixed on the two mounting brackets, and the output end of the electric push rod can pass through the circular opening.

[0013] Furthermore, the drive assembly includes a lead screw rotatably disposed inside the base, which passes through the moving block and is threadedly connected to it. A drive motor is bolted to the outer wall of one end of the base, and the output end of the drive motor is keyed to one end of the lead screw.

[0014] Furthermore, the clamping mechanism includes mounting grooves on the inner walls of both sides of the material feeding groove, and clamping blocks are movably provided in the mounting grooves. Each clamping block has a triangular groove at one end. The sliding tube is rotatably connected to a connecting plate at one end in the material feeding groove, and both ends of one side of the connecting plate are fixed with extrusion pins. One end of each of the two extrusion pins is inserted into the two triangular grooves.

[0015] Furthermore, multiple guide pins are fixed to the inner wall of one side of the mounting groove, and the other end of each guide pin is slidably inserted into the clamping block.

[0016] Furthermore, each of the slide tubes is equipped with a push rod, and a second magnetic block is fixed to one end of each push rod. Each of the guide rods has a guide groove on both sides, and a first magnetic block is fixed to one end of each guide groove away from the slide. The first and second magnetic blocks on the same side repel each other magnetically. A discharge port is provided on both sides of the upper part of the base near the position of the first magnetic block.

[0017] Furthermore, an L-shaped bracket is fixed to one end of the base, and the two racks and the guide rod are all fixed to the L-shaped bracket by connecting blocks.

[0018] Furthermore, a fixing groove is fixed on one side of the bottom of the base near the grinding wheel, and a tactile switch is fixed on the upper end of one side of the fixing groove. The tactile switch is used to control the opening and closing of the two grinding motors. A slider is slidably arranged in the fixing groove. When the slider slides up, it can contact the tactile switch. A pulley is rotatably arranged on one side of the slider. Multiple connecting posts are fixed on the lower end of one side of the moving block, and a pressing guide rod is fixed on the other end of the multiple connecting posts. When the moving block slides back and forth, it can press the pulley to move up or down. Two limiting pins are fixed in the fixing groove, and the limiting pins pass through the slider and are slidably connected to it. Springs are sleeved on both the upper and lower ends of the limiting pins.

[0019] The present invention also provides a polishing method for polishing the end face of an aluminum rod in a cigarette box package, comprising the following steps:

[0020] S1, when in use, turn on the drive motor and drive the moving seat to the position of the two slide rails through the lead screw, so that the two material cylinders are aligned with the push-out notches on the two slide rails. The electric push rod pushes the aluminum rod to feed the material. After feeding, the moving seat continues to move. The two slide tubes contact the guide rod and slide from the narrow part to the wide part of one end of the guide rod, so that the two slide tubes are inserted into the two material cylinders respectively.

[0021] S2, the connecting plate, drives the two extrusion pins to press the triangular grooves at one end of the two clamping blocks, thereby clamping the aluminum rods. After the aluminum rods are clamped, the moving seat continues to move, the toothed ring contacts the toothed rack, and drives the two material cylinders and the aluminum rods to rotate. When the moving seat moves to the position of the grinding wheel, the lower extrusion guide rod presses the pulley, causing the slider to move up and contact the tactile switch, turning on the two grinding wheels to grind the two aluminum rods.

[0022] S3, the moving seat continues to move. After the grinding is completed, the moving seat moves to the other end of the base, the pressure guide rod disengages from the pulley, and the grinding wheel closes.

[0023] S4, at the same time the two slide tubes slide to the other end of the guide rod, releasing the internal clamping mechanism, and the aluminum rod is no longer clamped;

[0024] S5, the two push rods slide to the position of the first magnetic block, and the push rods push out the aluminum rod under the repulsive force between the first and second magnetic blocks, and the material is discharged from the discharge port.

[0025] Advantages of the present invention: By means of the provided moving seat and the two material placing cylinders rotatably arranged on the moving seat in cooperation with the slideways, clamping mechanisms, etc., when using it for grinding, the moving seat can be driven to move to the positions of the two slideways, so that the two material placing cylinders are aligned with the pushing gaps on the two slideways. The electric push rod pushes the aluminum rod for feeding. After feeding, it continues to move. The two slide tubes contact the guide rod, driving the clamping mechanism inside the material placing cylinder to clamp the aluminum rod. Then, the gear ring contacts the rack, driving the two material placing cylinders and the aluminum rod to rotate automatically. The moving seat continues to move to the grinding wheel, and the two grinding wheels automatically grind the two aluminum rods. The moving seat continues to move. After grinding, the moving seat moves to the other end of the base. The two slide tubes slide to the other end of the guide rod, releasing the internal clamping mechanism. The two push rods simultaneously slide to the position of the first magnet. The push rod inside the slide tube pushes the aluminum rod out under the repulsive force of the first magnet and the second magnet. This device has functions of automatic feeding, automatic clamping, automatic grinding, and automatic discharging, is convenient to use, and has a relatively low overall cost.

Both ends of one side of the upper part of the base 1 are fixed with slides 2, and the slides 2 are inclined. The lower ends of the two slides 2 are close to each other and have push-out notches 29. The other side of the slides 2 is provided with push-out components. The moving seat 4 moves to the position of the two slides 2, so that the two material cylinders 5 are aligned with the push-out notches 29 on the two slides 2. The push-out components push the aluminum rod to feed the material.

[0042] Mounting plates 12 are fixed at the middle positions on both sides of the upper part of the base 1, and a grinding wheel 17 is rotatably mounted on one side of the mounting plate 12, while a grinding motor 16 for driving the grinding wheel 17 is fixed on the other side of the mounting plate 12.

[0043] The base 1 has a strip groove 8, and a moving block 14 is slidably arranged in the strip groove 8. The base 1 has a drive component for driving the moving block 14 to slide, and a moving seat 4 is fixed on the upper part of the moving block 14. The moving seat 4 is U-shaped, and a through opening is opened on both sides of the moving seat 4. A material cylinder 5 is rotatably arranged in the through opening. A material groove 30 is coaxially opened on one end of the material cylinder 5 near the slide 2, and a clamping mechanism is arranged in the material groove 30. A slide tube 27 is slidably inserted into the other end of the material cylinder 5. The slide tube 27 is used to drive the internal clamping mechanism to clamp or release.

[0044] Each of the material feeding cylinders 5 is fitted with a toothed ring 28 at the end away from the slide 2. Two toothed racks 7 are fixed on the upper part of the base 1. When the moving seat 4 moves to the position of the toothed racks 7, the two toothed rings 28 mesh with the two toothed racks 7 respectively, so that when the moving seat 4 continues to move, it drives the two material feeding cylinders 5 and the aluminum rod to rotate.

[0045] In use, the drive motor 20 is turned on, which drives the moving seat 4 to move to the position of the two slide rails 2 via the lead screw 21, so that the two material cylinders 5 are aligned with the push-out notches 29 on the two slide rails 2. The electric push rod 3 pushes the aluminum rod to feed the material. After feeding, the moving seat 4 continues to move, and the two slide tubes 27 contact the guide rod 6 and slide from the narrow part to the wide part of one end of the guide rod 6, so that the two slide tubes 27 are inserted into the two material cylinders 5 respectively. The connecting plate 34 drives the two extrusion pins 36 to press the triangular grooves 33 at one end of the two clamping blocks 32, so that the two clamping blocks 32 clamp the aluminum rod. After the aluminum rod is clamped, the moving seat 4 continues to move, and the toothed ring 28 contacts the rack 7, which drives the two material cylinders 5 and the aluminum rod to rotate. The moving seat 4 moves to the grinding wheel 1. When at position 7, the lower extrusion guide rod 13 extrudes the pulley 22, causing the slider 23 to move upward and contact the tactile switch 26, activating the two grinding wheels 17 to grind the two aluminum rods. The moving seat 4 continues to move. After grinding, the moving seat 4 moves to the other end of the base 1, the extrusion guide rod 13 disengages from the pulley 22, the grinding wheel 17 closes, and at the same time, the two sliding tubes 27 slide to the other end of the guide rod 6, releasing the internal clamping mechanism. The aluminum rods are no longer clamped, and the two push rods 37 slide to the position of the first magnetic block 19. Under the repulsive force between the first magnetic block 19 and the second magnetic block 38, the push rods 37 push out the aluminum rods, which are discharged from the discharge port 10. It has automatic feeding, automatic clamping, automatic grinding, and automatic unloading, is convenient to use, and has a low overall cost.

[0046] A guide rod 6 is fixed at the upper part of the base 1 between the two grinding wheels 17. The guide rod 6 is divided into narrow sections at both ends and a wide section in the middle. When the moving seat 4 slides, one end of each of the two slide tubes 27 slides on the two side walls of the guide rod 6. After the two slide tubes 27 come into contact with the guide rod 6, they slide from the narrow section to the wide section at one end of the guide rod 6, so that the two slide tubes 27 are inserted into the two material cylinders 5, driving the internal clamping mechanism to clamp them. A support rod 39 is fixed at the bottom of the slide 2, and the lower end of the support rod 39 is fixed to the base 1.

[0047] The ejection assembly includes two electric push rods 3. The lower end of the slide 2 away from the ejection notch 29 has a round opening 41, and a mounting bracket 40 is fixed on one side of the slide 2 at the position of the round opening 41. The two electric push rods 3 are respectively fixed on the two mounting brackets 40, and the output end of the electric push rod 3 can pass through the round opening 41.

[0048] The drive assembly includes a lead screw 21 rotatably disposed inside the base 1, and the lead screw 21 passes through the moving block 14 and is threadedly connected to it. A drive motor 20 is bolted to the outer wall of one end of the base 1, and the output end of the drive motor 20 is keyed to one end of the lead screw 21.

[0049] The clamping mechanism includes mounting grooves 31 on both sides of the inner wall of the material storage groove 30, and clamping blocks 32 are movably installed in the mounting grooves 31. One end of each clamping block 32 has a triangular groove 33. One end of the sliding tube 27 is rotatably connected to the connecting plate 34 in the material storage groove 30, and both ends of the connecting plate 34 are fixed with extrusion pins 36. One end of each of the two extrusion pins 36 is inserted into the two triangular grooves 33. After the two sliding tubes 27 come into contact with the guide rod 6, they slide from the narrow part to the wide part of one end of the guide rod 6, so that the two sliding tubes 27 are inserted into the two material storage cylinders 5 respectively. The connecting plate 34 drives the two extrusion pins 36 to press the triangular grooves 33 at one end of the two clamping blocks 32, thereby clamping the aluminum rod with the two clamping blocks 32.

[0050] Multiple guide pins 35 are fixed on one side of the inner wall of the mounting groove 31, and the other end of each guide pin 35 is slidably inserted into the clamping block 32.

[0051] Push rods 37 are slidably installed inside the slide tube 27, and a second magnetic block 38 is fixed at one end of each push rod 37. Guide grooves 18 are opened on both sides of the guide rod 6, and a first magnetic block 19 is fixed at the end of each guide groove 18 away from the slide 2.

When the slider 23 slides upward, it can contact the tactile switch 26. A pulley 22 is rotatably arranged on one side of the slider 23. Multiple connecting posts 15 are fixed on the lower end of one side of the moving block 14, and a pressing guide rod 13 is fixed on the other end of the multiple connecting posts 15. When the moving block 14 slides back and forth, it can press the pulley 22 to move up or down. When the moving base 4 moves to the position of the grinding wheel 17... The lower extrusion guide rod 13 extrudes the pulley 22, causing the slider 23 to move upward and contact the tactile switch 26, activating the two grinding wheels 17 to grind the two aluminum rods. After grinding, the moving seat 4 moves to the other end of the base 1, the extrusion guide rod 13 disengages from the pulley 22, the grinding wheels 17 close, and two limit pins 24 are fixed in the fixing groove 11. The limit pins 24 pass through the slider 23 and slide with it. Springs 25 are sleeved at both ends of the limit pins 24, allowing the slider 23 to move in both directions. When the extrusion guide rod 13 returns to its original position, the extrusion pulley 22 moves downward to prevent the grinding wheels 17 from starting again when returning to their original position.

[0054] The present invention also provides a polishing method for polishing the end face of an aluminum rod in a cigarette box package, comprising the following steps:

[0055] S1, when in use, the drive motor 20 is turned on and the moving seat 4 is moved to the position of the two slide rails 2 through the lead screw 21, so that the two material cylinders 5 are aligned with the push-out notches 29 on the two slide rails 2. The electric push rod 3 pushes the aluminum rod to feed the material. After feeding, the moving seat 4 continues to move. The two slide tubes 27 contact the guide rod 6 and slide from the narrow part to the wide part at one end of the guide rod 6, so that the two slide tubes 27 are inserted into the two material cylinders 5 respectively.

[0056] S2, connecting plate 34, drives two extrusion pins 36 to press the triangular grooves 33 at one end of two clamping blocks 32, thereby clamping the aluminum rods. After the aluminum rods are clamped, the moving seat 4 continues to move, the toothed ring 28 contacts the toothed rack 7, and drives the two material cylinders 5 and the aluminum rods to rotate. When the moving seat 4 moves to the position of the grinding wheel 17, the lower extrusion guide rod 13 presses the pulley 22, causing the slider 23 to move up and contact the tactile switch 26, opening the two grinding wheels 17 to grind the two aluminum rods.

[0057] S3, the moving seat 4 continues to move. After the grinding is completed, the moving seat 4 moves to the other end of the base 1, the squeezing guide rod 13 disengages from the pulley 22, and the grinding wheel 17 is closed.

[0058] S4, at the same time, the two slide tubes 27 slide to the other end of the guide rod 6, releasing the internal clamping mechanism, and the aluminum rod is no longer clamped;

[0059] S5, the two push rods 37 slide to the position of the first magnetic block 19, and the push rods 37 push out the aluminum rod under the repulsive force between the first magnetic block 19 and the second magnetic block 38, and discharge it from the discharge port 10.

[0060] The working principle of this invention is as follows: In use, the drive motor 20 is turned on, and the lead screw 21 drives the moving seat 4 to the positions of the two slide rails 2, so that the two material cylinders 5 are aligned with the push-out notches 29 on the two slide rails 2. The electric push rod 3 pushes the aluminum rod to feed the material. After feeding, the moving seat 4 continues to move, and the two slide tubes 27 contact the guide rod 6, sliding from the narrow part to the wide part at one end of the guide rod 6, so that the two slide tubes 27 are inserted into the two material cylinders 5. The connecting plate 34 drives the two extrusion pins 36 to press the triangular grooves 33 at one end of the two clamping blocks 32, thereby clamping the aluminum rod. After the aluminum rod is clamped, the moving seat 4 continues to move, and the toothed ring 28 contacts the rack 7, driving the two material cylinders 5 to feed the aluminum rod. The material cylinder 5 and the aluminum rod rotate. When the moving seat 4 moves to the position of the grinding wheel 17, the lower extrusion guide rod 13 extrudes the pulley 22, causing the slider 23 to move upward and contact the tactile switch 26, turning on the two grinding wheels 17 to grind the two aluminum rods. The moving seat 4 continues to move. After grinding is completed, the moving seat 4 moves to the other end of the base 1, the extrusion guide rod 13 disengages from the pulley 22, the grinding wheel 17 closes, and at the same time the two slide tubes 27 slide to the other end of the guide rod 6, releasing the internal clamping mechanism. The aluminum rod is no longer clamped, and the two push rods 37 slide to the position of the first magnetic block 19. Under the repulsive force between the first magnetic block 19 and the second magnetic block 38, the push rods 37 push out the aluminum rod, which is discharged from the discharge port 10.
