Description

Technical Field

[0001] The utility model relates to the technical field of can lid processing, in particular to a can lid discharging device for a numerical control can lid punching machine. Background Technique

[0002] In the prior art, after a numerical control can lid punching machine completes feeding, pressing, punching, and can lid forming, the metal can lid is lifted together with the upper die. After reaching a certain height, the metal can lid is separated from the forming surface of the upper die under the action of a stripping ring. At this time, the metal can lid continues to rise due to inertia until it reaches the highest point. At the same time, the air nozzle valve opens to release compressed air, and the metal can lid is blown out of the forming die in the horizontal direction, and the blown metal can lid falls onto the conveying conveyor belt.

[0003] Chinese Utility Model Patent CN209379808U discloses a can lid discharging device for a numerical control can lid punching machine, including a chassis. A punching head is installed on the chassis. A conveyor belt is provided on one side of the chassis, and the conveyor belt is installed on a bracket. A baffle is provided on the bracket close to the chassis. The baffle is composed of an inclined head plate and a parallel plate, and one end of the inclined head plate is welded to the parallel plate. An airbag is embedded on the surface of the inclined head plate close to the conveyor belt, and the airbag communicates with an inflation hole. The inflation hole is connected with an inflation pipe. By arranging an airbag on the bottom surface of the inclined head plate, the softness of the inflated airbag is used to protect the can lid when it collides with the ejected can lid, avoiding bumps. By movably installing a plug-in plate on the bottom surface of the parallel plate and fixedly connecting a soft rubber baffle strip to the bottom surface of the plug-in plate, and the length of the soft rubber baffle strip is in a decreasing state, the ejection speed of the can lid is slowed down, the inertia during falling is reduced, and the can lid is prevented from bouncing off the conveyor belt after falling.

[0004] However, the existing can lids are directly blown onto the conveyor belt on the conveyor rack after being processed by the punching machine, resulting in some can lids being deformed when contacting the conveyor belt on the conveyor rack, leading to low production quality.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1 - 3, the utility model discloses a can lid discharging device for a numerical control can lid punching machine, which includes a numerical control can lid punching machine main body 3 and a scraper 5. A mold 4 is arranged on the numerical control can lid punching machine main body 3, a control punch head 2 is arranged on the numerical control can lid punching machine main body 3, a control panel 1 is arranged on the numerical control can lid punching machine main body 3. A conveying frame 8 is fixedly installed at the rear end of the numerical control can lid punching machine main body 3. An L-shaped fixing plate 9 is fixedly installed at a position near the rear end on the left side of the top of the conveying frame 8. A sponge 11 is fixedly installed on the front surface of the L-shaped fixing plate 9. A rubber sleeve 10 is fixedly installed around the L-shaped fixing plate 9. A buffer plate 6 is fixedly installed at a position near the lower surface on the right side of the conveying frame 8. Slide grooves 15 are respectively opened at positions near the right side on the front and rear end walls inside the conveying frame 8. Slide rods 12 are respectively fixedly installed at positions near the front and rear ends on the left and right side walls inside the two slide grooves 15. Bearing seats 14 are respectively fixedly installed at the centers of the left side walls inside the two slide grooves 15. Tightening bolts 7 are respectively threadedly connected at positions near the front and rear ends on the right side of the conveying frame 8. Slide blocks 13 are respectively threadedly connected to the outer surfaces of the two tightening bolts 7 through screw threads.

[0024] Specifically, the adjacent ends of the front and rear ends of the scraper 5 near the left side are respectively fixedly connected to the adjacent ends of the two slide blocks 13.

[0025] In this implementation scheme, it is convenient for the subsequent rotation of the tightening bolts 7 to drive the movement of the two slide blocks 13 respectively.

[0026] Specifically, the left sides of the two tightening bolts 7 respectively penetrate through the positions near the front and rear ends on the right side of the conveying frame 8 and respectively extend into the two slide grooves 15 and are respectively movably sleeved on the right sides of the two bearing seats 14.

[0027] In this implementation scheme, when it is convenient to subsequently turn the tightening bolts 7, the stability of the tightening bolts 7 is enhanced.

[0028] Specifically, through grooves are respectively opened at positions near the front and rear ends on the right sides of the two slide blocks 13. The inner parts of the multiple through grooves are respectively movably sleeved on the outer surfaces of the multiple slide rods 12. The outer surfaces of the two slide blocks 13 are respectively movably sleeved inside the two slide grooves 15.

[0029] In this implementation scheme, the stability of the slide blocks 13 during movement is enhanced.

[0030] Specifically, the front and rear ends of the scraper 5 are respectively arranged at positions near the right side inside the conveying frame 8. The left side of the scraper 5 is close to the surface of the conveyor belt on the conveying frame 8.

[0031] In this implementation scheme, it is convenient for the subsequent scraper 5 to scrape up the can lids close to the surface of the conveyor belt on the conveying frame 8, thereby reducing production costs and avoiding waste of resources.

[0032] Specifically, the buffer plate 6 is located at the bottom of the scraper 5.

[0033] In this implementation, through the buffer plate 6, the impact force when the can lid falls can be reduced, thereby reducing the stress on the can lid when it falls.

[0034] Specifically, a discharge port is provided on the main body 3 of the numerically controlled can lid punching machine, and the conveyor rack 8 is located at the rear end of the discharge port.

[0035] Specifically, the rubber sleeve 10 wraps the sponge 11 and is connected to the L-shaped fixing plate 9, and the connection between the rubber sleeve 10 and the sponge 11 is fixed by positioning nails.

[0036] In this implementation, without affecting the buffering of the can lid, the sponge 11 is protected to extend the service life of the sponge 11.

[0037] During use, according to the size of the can lid, turn the tightening bolt 7. The rotation of the tightening bolt 7 drives the slider 13 and the scraper 5 to move to the left, so that the slider 13 drives the scraper 5 along the slide bar 12 to close to the surface of the conveyor belt on the conveyor rack 8. The can lid processed by the main body 3 of the numerically controlled can lid punching machine is blown out of the discharge port and blown onto the surface of the rubber sleeve 10. When the can lid is blown onto the rubber sleeve 10, it is buffered by the sponge 11 and the rubber sleeve 10. The can lid buffered by the sponge 11 and the rubber sleeve 10 falls on the conveyor belt of the conveyor rack 8 and is then hooked by the scraper 5 to the buffer plate 6. The can lid passing through the buffer plate 6 is conveyed to the next process. When the can lid is conveyed to the buffer plate 6, the impact force when the can lid falls can be reduced, thereby reducing the stress on the can lid when it falls.

[0038] In summary, for the can lid discharging device of the numerically controlled can lid punching machine, by setting the rubber sleeve 10, the sponge 11 and the L-shaped fixing plate 9, it can buffer the can lid after it is discharged from the main body of the numerically controlled can lid punching machine, avoid the can lid from directly colliding with other hard objects, and improve the production quality of the can lid; by setting the conveyor rack 8 and the buffer plate 6, the processed can lid can be conveyed to the next process, and when the can lid falls from the conveyor rack 8, the buffer plate 6 can reduce the impact force when the can lid falls, thereby reducing the stress on the can lid when it falls; by setting the scraper 5, the tightening bolt 7, the slide bar 12, the slider 13, the chute 15 and the tightening bolt 7, the distance between the scraper 5 and the conveyor belt on the conveyor rack 8 can be freely adjusted, and the scraper 5 can scrape off the can lids adsorbed on the conveyor belt of the conveyor rack 8 to ensure that the can lids are sent to the buffer plate 6 and flow into the next process through the buffer plate 6, so that when the equipment is in use, the dropping of the can lids can be reduced, thereby reducing the production cost and quality and avoiding waste of resources.
