Detailed implementation manners

[0031] Example, as Figures 1 - 16As shown in the figure, a puzzle card die-cutting automatic feeding device includes: a device frame 4; a lifting frame 1, a feeding device 3 and a controller are fixedly installed on the device frame 4. A placement box 2 for placing cardboard is fixedly installed at the output end of the lifting frame 1; a cutting mechanism and a clamping mechanism 8 are provided on the device frame 4. The cutting mechanism is used to cut the cardboard, and the clamping mechanism 8 is used to fix the cardboard when the cutting mechanism cuts the cardboard; the feeding device 3 is used to send the cardboard on the placement box 2 to the cutting mechanism; a discharging device 7 is slidably installed on the device frame 4, and the discharging device 7 is used to transport the cut cardboard out; the lifting frame 1, the feeding device 3, the cutting mechanism, the discharging device 7 and the clamping mechanism 8 are all electrically connected to the controller; when starting to cut the cardboard, first, a stack of cardboard is placed in the placement box 2 by the staff, the lifting frame 1 is started, so that the cardboard in the placement box 2 is transported to the lower end of the feeding device 3, the feeding device 3 is started, and the feeding device 3 sends the cardboard in the placement box 2 to the cutting mechanism one by one. The cutting mechanism performs die-cutting on the cardboard, and after the die-cutting is completed, the die-cut cards are transported away through the discharging device 7.

[0032] Specifically, as Figures 3 - 6 shown in the figure, the feeding device 3 includes: a mounting frame 31; the mounting frame 31 is fixedly installed on the device frame 4; a protective frame 32 is fixedly installed on the mounting frame 31; a cam 34 is rotatably installed on the mounting frame 3, and a pushing motor 33 is fixedly installed, and the output shaft of the pushing motor 33 is fixedly connected to the cam 34; a push rod 39 is also rotatably installed on the mounting frame 31, the push rod 39 is elastically connected to the protective frame 32 through a spring, the push rod 39 contacts the cam 34, and an avoidance space matching the push rod 39 is provided on the protective frame 32;

[0033] Two pushing rollers 38 are rotatably mounted on the mounting frame 31. A gear 37 is fixedly mounted on each pushing roller 38, and the two gears 37 are meshed with each other; the mounting frame 31 is also rotatably mounted with a first driving wheel 35 and a second driving wheel 36. The first driving wheel 35 and the second driving wheel 36 are connected by a transmission belt. The first driving wheel 35 is fixedly connected to the output shaft of the pushing motor 33, and the second driving wheel 36 is fixedly connected to one of the pushing rollers 38; an empty space that only allows a single cardboard to pass through is provided at one end of the guard frame 32 close to the pushing roller 38; the pushing motor 33 is electrically connected to the controller; after the staff puts the cardboard into the placement box 2, the lifting frame 1 is started so that the cardboard above the placement box 2 is sent to the lower end of the guard frame 32. Then the pushing motor 33 is started to make the cam 34 rotate, thereby driving the push rod 39 to rotate. Under the cooperation of the spring and the cam 34, the uppermost cardboard is sent between the two pushing rollers 38 through the empty space at the upper end of the guard frame 32. When the cardboard enters the gap between the two pushing rollers 38, under the action of friction, the two pushing rollers 38 send the cardboard into the cutting mechanism during rotation for die-cutting; while the pushing motor 33 is working, the first driving wheel 35 will also rotate and drive the second driving wheel 36 to rotate through the transmission belt, so that the two pushing rollers 38 rotate. The diameter of the first driving wheel 35 is larger than the diameter of the second driving wheel 36. Therefore, when the pushing motor 33 is working, the rotation speed of the cam 34 is less than the rotation speed of the pushing rollers 38, so that the cardboard is completely sent into the cutting mechanism, and after the cutting is completed, the next cardboard is sent between the two pushing rollers 38, thus avoiding the problem that the feeding is too fast and the cutting mechanism cannot cope with it.

[0034] Specifically, a sliding plate 310 is fixedly mounted on the mounting frame 31; the sliding plate 310 is located between the mounting frame 31 and the cutting mechanism. The upper end of the push rod 39 is rotatably connected to the mounting frame 31, and the lower end is fixedly mounted with a rubber block; an empty space matching the rubber block is provided on the guard frame 32; through the sliding plate 310, the cardboard can fall into the cutting mechanism more smoothly. The rubber block can increase the friction between the push rod 39 and the cardboard and prevent damage to the cardboard.

After the cutting is completed, the discharging device 7 conveys the cut cards on the placement plate 6 away.

[0036] Specifically, as Figure 2 shown in the figure, the cutting member 5 includes: a cutting electric cylinder 51; the cutting electric cylinder 51 is fixedly installed on the equipment frame 4, and a cutting plate 52 is fixedly installed at the output end.

After the cutting is completed, the moving motor is started to make the moving gear 61 rotate, thereby driving the placement plate 6 to move above the discharging device 7, and the discharging device 7 sends out the cut cardboard on the placement plate 6.

[0037] Specifically, as Figures 12 - 13 shown in the figure, the clamping mechanism 8 includes: a carrier plate 81, a carrier table 87, a connecting rod 84, and a clamping electric cylinder 86; the carrier plate 81 is fixedly installed on the carrier table 87, the carrier table 87 is slidably installed on the equipment frame 4, a lifting rack 88 is fixedly installed on the carrier plate 81, and the lifting rack 88 is slidably installed on the equipment frame 4; a lifting motor is fixedly installed on the equipment frame 4 and a lifting gear 89 is rotatably installed, the output shaft of the lifting motor is fixedly connected to the lifting gear 89, and the lifting gear 89 is meshed with the lifting rack 88; the auxiliary device 9 is rotatably installed on the carrier table 87;

[0038] Four sliders 82 are slidably installed on the carrier plate 81, and a fixing frame 83 is fixedly installed on each slider 82; a central plate 85 is rotatably installed at the center of the carrier plate 81; there are four connecting rods 84, one end of each connecting rod 84 is rotatably connected to the corresponding slider 82, and the other end is rotatably installed on the central plate 85; the angle between every two adjacent sliders 82 is 90 degrees;

[0039] Between two opposite sliders 82, two clamping electric cylinders 86 are provided. The base and the output end of each clamping electric cylinder 86 are fixedly connected to the corresponding slider 82; the lifting motor and each clamping electric cylinder 86 are electrically connected to the controller; when the lifting motor is started, it can drive the carrier plate 81 to move up and down, and drive the auxiliary device 9 to move up and down. When the two clamping electric cylinders 86 work, they drive the four fixing frames 83 to move towards the center of the carrier plate 81 at the same time, or move away from the center of the carrier plate 81 at the same time, so as to fix and correct the position of the cardboard when the cutting piece 5 cuts the cardboard on the placing plate 6, prevent the cardboard from shifting, and reduce the product quality.

[0040] Specifically, as Figures 9 - 11 shown, the auxiliary device 9 includes: an auxiliary plate 91; the auxiliary plate 91 is rotatably installed on the carrier 87 and is fixedly installed with a rotating gear 92; a rotating electric cylinder 94 is fixedly installed on the carrier 87 and a rotating rack 93 is slidably installed; the output end of the rotating electric cylinder 94 is fixedly connected to the rotating rack 93, and the rotating gear 92 is meshed with the rotating rack 93;

[0041] The placing plate 6 is provided with a plurality of rectangular voids, and the auxiliary plate 91 is provided with rectangular protrusions that are in one-to-one correspondence with each rectangular void on the placing plate 6; the rotating electric cylinder 94 is electrically connected to the controller; a waste collection box is fixedly installed on the side of the equipment frame 4. After the cardboard is cut, the placing plate 6 moves above the discharging device 7, and then the rotating electric cylinder 94 is started, so that the auxiliary plate 91 rotates, and the auxiliary plate 91 pours the cut waste into the waste collection box; prevent the waste generated by cutting from affecting the cutting of the next cardboard, and can keep the equipment clean.

[0042] Specifically, as Figures 14 - 15 shown, the discharging device 7 includes: a moving table 71; the moving table 71 is slidably installed on the equipment frame 4, and a discharging lifting electric cylinder 72 is fixedly installed on the equipment frame 4, and the output end of the discharging lifting electric cylinder 72 is fixedly connected to the moving table 71;

[0043] Rollers that are in one-to-one correspondence with each rectangular void on the placing plate 6 are rotatably installed on the moving table 71, and the two adjacent rollers are driven to rotate in the same direction; a discharging motor is fixedly installed on the moving table 71, and the output shaft of the discharging motor is fixedly connected to one of the rollers; the discharging lifting electric cylinder 72 and the discharging motor are both electrically connected to the controller; when the placing plate 6 moves above the moving table 71, the discharging lifting electric cylinder 72 is started, so that the rollers on the moving table 71 respectively enter the corresponding voids on the placing plate 6, and then the discharging motor is started to convey the cut cards on the placing plate 6 away.

[0044] Working principle: When starting to use, first lower the lifting frame 1. The staff place a stack of cardboard into the placement box 2. Then, through the lifting frame 1, the cardboard in the placement box 2 is sent directly below the guard frame 32. Start the pushing motor 33 to make the cam 34 and the first transmission wheel 35 rotate. When the cam 34 rotates, through cooperation with the spring, the push rod 39 makes a reciprocating swinging motion. Thus, the rubber block at the lower end of the push rod 39 and the clearance above the guard frame 32 push the topmost cardboard, pushing the cardboard between the two pushing rollers 38; through the clearance on one side of the guard frame 32 close to the two pushing rollers 38, the push rod 39 can only push out one cardboard each time, preventing multiple cardboards from being pushed out at once due to the friction between the cardboards. When the first transmission wheel 35 rotates, the second transmission wheel 36 is rotated through the transmission belt, so that the two pushing rollers 38 rotate. The cardboard between the two pushing rollers 38 is sent to the placement plate 6 under the action of friction; at regular intervals, that is, the time when one cardboard is cut, the lifting frame 1 rises by a height equivalent to the thickness of one cardboard to ensure that the push rod 39 can feed the cardboard;

[0045] After the cardboard is sent to the placement rack 6, start the lifting motor and the cutting electric cylinder 51. Through the lifting motor, the auxiliary plate 91 rises, and the rectangular protrusions on the auxiliary plate 91 are inserted into the rectangular clearances on the placement rack 6 to be flush with the upper surface of the placement rack 6. Then, the two clamping electric cylinders 86 are started, so that the four sliders 82 drive the four fixing frames 83 to move towards the center of the carrier plate 81, clamping and correcting the position of the cardboard on the placement rack 6; then the cutting electric cylinder 51 works, driving the cutting plate 52 to move downward. After cutting is completed, the cutting electric cylinder 51 drives the cutting plate 52 to reset. The two clamping electric cylinders 86 extend to release the cardboard. The lifting motor drives the auxiliary plate 91 to descend by a certain distance. At this time, the debris after cutting the cardboard falls onto the auxiliary plate 91 through the clearance on the placement plate 6. The moving motor is started to make the placement plate 6 move directly above the moving table 71. The discharging lifting electric cylinder 72 is started to make the moving table 71 rise until the rollers on the moving table 71 are inserted into the corresponding clearances on the placement plate 6. The discharging motor is started to make the rollers on the moving table 71 start to rotate, transporting the cut cardboard on the placement plate 6 away;

[0046] After the placement plate 6 moves above the moving table 71, the lifting motor is started again to make the auxiliary plate 91 rise until the bottom surface of the auxiliary plate 91 is flush with the upper surface of the waste collection box. The rotating electric cylinder 94 is started to make the auxiliary plate 91 rotate 90°, pouring the waste obtained after cutting the cardboard into the waste collection box, preventing it from affecting the cutting effect when cutting the next cardboard and keeping the equipment clean.

[0047] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
