Description

Technical Field

[0001] The utility model belongs to the technical field of metal processing and relates to a three-in-one automatic feeder. Background Art

[0002] A three-in-one feeder is a specialized device for stamping or blanking metal coils. It integrates feeding, straightening, and a material rack into a fully automatic feeding device. Because thick sheet metal is typically packaged in a coiled structure, both a coil unwinder and a leveler are required for processing. The coil unwinder is used for unwinding, while the leveler is primarily used to flatten the uneven metal sheet after unwinding.

[0003] A CNC three-in-one feeder disclosed in Chinese patent CN213728983U, when the feeder is in use, the material roll is placed on the top of the support seat, and the support seat is driven to rise and fall by the cylinder, so that the center of the material roll matches the center of the expansion and contraction reel, the motor 2 drives the rotating rod to rotate, and the rotating rod drives the roller to rotate on the slide, so that the loading trolley can move back and forth, and the material roll is installed on the expansion and contraction reel, the motor 1 drives the material blocking arm to rotate, and the hydraulic device drives the motor 1 to contract, so that the back of the material blocking arm contacts the front of the material roll, and the material blocking arm limits the material roll, and the rotating wheel drives the screw to rotate. The rotation of the screw causes the movable seat to move, thereby driving the limit block to move, adjusting the spacing between the limit blocks, and limiting the material transported into the leveling feeding mechanism.

[0004] This feeder features a material ring control mechanism consisting of a press arm and a support arm, positioned one above the other. The press arm positions the top of the roll. As the material rolls out, the roll's diameter gradually decreases, requiring independent adjustment of the press arm. Failure to adjust the ring in a timely manner can lead to loose material.

The second slider 59 is slidably connected in the slide groove. The top of the second slider 59 is fixedly connected to the second limiting rod 60.

[0068] Working principle:

[0069] When in use, the material roll is wound on the reel, and the wound material roll is placed on the V-shaped frame 11, with the opening of the reel inside the material roll facing the box body 1.

[0070] The first electric push rod 9 is activated, pushing the V-shaped frame 11 upward, driving the slide rod 12 upward, so that the bottom end of the slide rod 12 slides inside the fixed rod 13, increasing the stability of the V-shaped frame 11. The V-shaped frame 11 will drive the roll upward until the opening of the roll is adapted to the height of the four supporting plates 5.

[0071] Push the trolley seat 8 toward the side close to the box body 1, and the roller at the bottom of the trolley seat 8 slides on the guide rail 10. Move the material roll toward the supporting plate 5 until all four supporting plates 5 are located in the reel.

[0072] Start the four second electric push rods 47 to push the supporting plate 5 to move on the inner wall of the roll until the four supporting plates 5 are all in contact with the inner wall of the roll. At this time, the material roll is fixed on the supporting plate 5, and the second nip roller 20 can be in contact with the top of the material roll.

[0073] Push the trolley seat 8 to the side away from the box body 1 to remove the V-shaped frame 11 from directly under the material coil without affecting the transportation of the coil.

[0074] Start the sixth motor 54 to drive the fifth rotating shaft 44 to rotate, so that the square shaft 42 rotates, and drives the sleeve 43 to rotate in the first slider 40, so that the first limiting rod 41 rotates toward the side close to the material roll until the two first limiting rods 41 are respectively located on both sides of the material roll.

[0075] The fourth motor 29 is activated to rotate the first screw 45, causing the two first sliders 40 to move toward each other along the first screw 45. The ends of the first sliders 40 slide on the fixed frame 19. The first sliders 40 push the two sleeves 43 toward each other on the square shaft 42, shortening the distance between the two first limiting rods 41 until the distance between the two first limiting rods 41 matches the width of the coil, thus positioning the coil.

[0076] Pull the material roll downward, the material roll will pass through one side of the guide plate 3, and finally move to the leveling machine 6.

[0077] The third motor 28 is started to drive the first rotating shaft 4 to rotate, so that the guide plate 3 rotates toward the supporting plate 5 until the guide plate 3 supports the bottom of the material roll to prevent the material roll from contacting the base 2.

[0078] The roll of material moved to the leveler 6 passes over the top of the rotating roller 16 , under the first nip roller 17 , and between the two second limiting rods 60 .

[0079] The second motor 18 is started, and its output shaft drives the fifth driving pulley 63 to rotate. This, in turn, drives the fifth driven pulley 62 via the fifth belt 55, thereby driving the fourth connecting shaft 58 to rotate. The second connecting plates 57 at both ends of the fourth connecting shaft 58 rotate, driving the first nip roller 17 to rotate around the rotation axis of the fourth connecting shaft 58 until the first nip roller 17 is located at the top of the material roll, positioning the material roll on the rotating roller 16.

[0080] Start the seventh motor 64 to drive the second screw 61 to rotate, so that the two second sliders 59 move toward each other in the slide groove, driving the two second limit rods 60 to move until the two second limit rods 60 are respectively located on both sides of the material roll, positioning the material roll entering the leveling machine 6.

[0081] When feeding, the first motor 14 is started, and the output shaft of the first motor 14 drives the third rotating shaft 25 to rotate through the first differential 23, so that the first driving wheel 24 rotates, and the second driven wheel 37 rotates through the first belt 27.

[0082] The second driven wheel 37 drives the first connecting shaft 35 and the rotating disk 30 to rotate, driving the support rod 46 and the entire material roll to rotate, gradually rotating the coiled material on the roll to feed the material.

[0083] The first connecting shaft 35 also drives the second driving pulley 36 to rotate, which in turn rotates the first driven pulley 33 via the third belt 34. The first driven pulley 33 rotates the input shaft of the second differential 31, which in turn rotates the output shaft of the second differential 31, which in turn rotates the third driving pulley 39. This in turn rotates the third driven pulley 38 via the second belt 32, which in turn rotates the second rotating shaft 21.

[0084] The second rotating shaft 21 drives the first connecting plate 22 to rotate, causing the second nip roller 20 to rotate about the rotation axis of the second rotating shaft 21. This allows the second nip roller 20 to rotate simultaneously with the material feed, ensuring that it continuously abuts against the top of the material roll. The abutment mechanism automatically adjusts to changes in the diameter of the material roll, reducing the risk of loose material. The leveler 6 is operated by the controller 7.

[0085] After the roll is delivered, the sixth motor 54 is started to rotate the first limiting rod 41 away from both sides of the roll. The second electric push rod 47 is started to pull the supporting plate 5 toward the side close to the support rod 46, thereby reducing the extended range of the supporting plate 5 and removing the roll from the supporting plate 5.

[0086] If the roll is wide, the fourth motor 29 drives the first screw 45 to rotate in the opposite direction, causing the two first sliders 40 to move away from each other. This pushes the sleeve 43 toward the ends of the square shaft 42, increasing the distance between the two first limiting rods 41. Similarly, the seventh motor 64 is activated to drive the second screw 61 to rotate in the opposite direction, causing the two second sliders 59 to move away from each other, increasing the distance between the two second limiting rods 60. Example 2

[0087] like Figures 9-11 As shown, the difference between this embodiment and embodiment 1 is that: in this embodiment, there is no fourth motor 29, and a second connecting shaft 51 is fixedly connected to one end of the first screw rod 45 extending into the housing 1, and the other end of the second connecting shaft 51 is rotatably connected to the inner wall of the housing 1. A fourth driven wheel 50 is fixedly sleeved on the second connecting shaft 51.

[0088] A third connecting shaft 53 is fixedly connected to one end of the first rotating shaft 4 extending into the housing 1. The other end of the third connecting shaft 53 rotates through the side of the housing 1. A fifth motor 48 is fixedly connected to the side of the housing 1 away from the base 2, and the fifth motor 48 drives the third connecting shaft 53 to rotate.

[0089] A fourth driving wheel 52 is fixedly mounted on the third connecting shaft 53 , and a fourth belt 49 is mounted on transmission sleeves of the fourth driving wheel 52 and the fourth driven wheel 50 .

[0090] Working principle:

[0091] The third connecting shaft 53 is rotated by activating the fifth motor 48 .

[0092] The third connecting shaft 53 drives the first rotating shaft 4 to rotate, so that the guide plate 3 rotates to support the material roll.

[0093] The third connecting shaft 53 rotates the fourth driving pulley 52, which in turn rotates the fourth driven pulley 50 via the fourth belt 49. This in turn rotates the second connecting shaft 51 and the first screw 45, thereby synchronously adjusting the first slider 40 and the guide plate 3. The specific adjustment position is based on the first slider 40; the guide plate 3 only needs to be located below the roll.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
