Description

Technical Field

[0001] The invention belongs to the technical field of production and processing of three-dimensional grating cards, and in particular relates to an automatic discharging mechanism for three-dimensional grating cards. Background Art

[0002] Three-dimensional grating stereoscopic cards are a type of three-dimensional painting. It is an ordinary flat painting processed with three-dimensional technology, and then a three-dimensional grating material is pasted on it. It uses the parallax of the human eyes to allow people to directly see the three-dimensional effect of the scenery in the painting. Most other three-dimensional paintings require the use of tools such as three-dimensional glasses or the need to adjust the observation state of the eyeballs to see the three-dimensional effect. Generally, three-dimensional grating stereoscopic cards are produced and processed by printing, and large quantities of cards can be produced at the same time.

[0003] During the production process of the cards, they are printed by a printing machine. After the finished cards are printed, they need to be cut and trimmed, and then they need to be packaged and processed. Since the three-dimensional cards are produced and processed by a printing machine, the processing volume is large. The existing production and processing equipment has poor conveying capacity when outputting the cards, and before and after the cards are cut and trimmed. The automation level is not high, and most of them are driven by multiple independent power devices, but there is little coordination and connection between the power devices, resulting in a low effective utilization rate of power, which is very likely to cause energy waste and increase operating costs. It is necessary to design a technical solution that can solve the above problems. Summary of the invention

[0004] The purpose of the embodiment of the present invention is to provide an automatic discharging mechanism for three-dimensional grating cards, aiming to solve the problem.

[0005] The present invention is implemented in this way. The structural diagram of the automatic discharge mechanism of three-dimensional grating cards includes: a card output channel and a card cutting table; drive shafts are rotatably arranged at both ends of the card output channel, and the drive shafts are used to drive the card output channel to rotate. At the same time, a discharge transfer vehicle for centralized stacking of three-dimensional grating cards is connected to the output end of the card output channel. The card cutting table is arranged on the side of the card output channel and the top is higher than the top of the card output channel. An automatic feeding device is arranged on the side of the card cutting table facing the discharge transfer vehicle, which is used to drive the printed three-dimensional grating cards to continuously move toward the card cutting The card cutting table is transported in the direction of the discharge table, and the automatic feeding device is connected to the driving shaft close to the side of the discharge transfer vehicle. The automatic feeding device drives the driving shaft to rotate while running, and then drives the card output channel to rotate and transport toward the discharge transfer vehicle. The top of the side wall of the card cutting table away from the automatic feeding device is provided with a cutting knife in a lifting manner. Elastic components are symmetrically provided on both sides of the cutting knife to ensure that the cutting knife can be lowered and has the ability to automatically return to the initial position. The lower part of the side wall of the cutting knife and the top of the side wall of the card cutting table are staggered and fitted. When the cutting knife descends, it is subjected to the staggered force between the cutting knife and the side wall of the card cutting table. The three-dimensional grating card passing by is cut quickly. A cutting knife pressure block is arranged directly above the cutting knife. A lifting mechanism is connected to the side of the cutting knife pressure block away from the card output channel. The lifting mechanism is rotatably connected to the automatic feeding device. The lifting mechanism cyclically lifts and lowers under the operation of the automatic feeding device, and synchronously drives the cutting knife pressure block to cyclically lift and lower. The maximum position of the cutting knife pressure block reaches the height of the upper surface of the cutting knife. A group of L-shaped pads are swingably arranged between the cutting knife pressure block and the cutting knife. A swing power device is arranged on the side of the L-shaped pad away from the cutting knife. The swing power device controls the L-shaped pad to swing in and out of the cutting knife pressure block and the cutting knife pressure block. Between the cutting knives, when the lifting mechanism drives the cutting knife pressing block to descend to the maximum position, under the action of the thickness of the L-shaped pad, the bottom of the cutting knife passes over the upper surface of the card cutting table downward to cut the three-dimensional grating card placed on the card cutting table. A card end positioning slot plate is arranged at the same height as the top of the card cutting table at the bottom of the swing power device to contact and cooperate with the moving three-dimensional grating card. The card end positioning slot plate is pushed by the three-dimensional grating card to synchronously drive the swing power device to operate, thereby pushing the L-shaped pad block to transfer between the cutting knife and the cutting knife pressing block to achieve cutting of the three-dimensional grating card.

[0006] Among them, the three-dimensional grating card to be cut after printing is transported toward the card cutting table along the automatic feeding device. When the end of the three-dimensional grating card contacts the card end positioning slot plate and pushes the card end positioning slot plate to control the operation of the swing power device, the L-shaped pad is controlled to be transferred between the cutting knife and the cutting knife pressure block, and then the cutting knife is driven to cut the three-dimensional grating card placed on the card cutting table. After cutting, the three-dimensional grating card is transferred to the card output channel under the action of gravity. At this time, the automatic feeding device runs and synchronously drives the card output channel to rotate, and automatically inputs the three-dimensional grating card into the inside of the discharge transfer vehicle for centralized stacking, thereby realizing the automatic feeding, continuous cutting and automatic discharge of the three-dimensional grating card in this scheme, and the various components are closely coordinated to fully improve the conversion utilization rate of power.

[0007] The three-dimensional grating card automatic discharging mechanism provided by the present invention drives the lower driving wheel and the upper driving wheel to control the automatic feeding of the three-dimensional grating card by setting two power sources of the lower servo motor and the upper servo motor, and then drives the cutting knife pressing block to rise and fall synchronously under the rotation connection of the transmission belt, the first bevel gear and the second bevel gear, and then moves the lower three-dimensional grating card, cooperates with the positioning slot plate at the end of the card, controls the swing rod to push the L-shaped pad in and out between the cutting knife and the cutting knife pressing block, and automatically cuts the three-dimensional grating card while maintaining the continuous input of the three-dimensional grating card, and then drives the cut three-dimensional grating card to fall to the card output channel driven by the lower servo motor while running and driving the rotating card output channel to output under the action of gravity. In the case of only setting two power sources of the lower servo motor and the upper servo motor, the technical solution utilizes the connection and position relationship between the components to realize the fully automatic working process of automatic entry, continuous cutting and automatic output of the three-dimensional grating card, and fully reduces the energy consumption, increases the effective use of power, and realizes efficient automatic work;

[0008] By setting the connecting block to slide in the slide groove, the distance adjustment hole is plugged with different rotating positioning pins, and the height of the upper driving wheel can be adjusted, the three-dimensional grating cards of different thicknesses can be cut, and the three-dimensional grating cards can be cut into different lengths, which fully improves the scope of use of the mechanism.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0020] like Figure 1-6As shown, it is a structural diagram of the automatic discharging mechanism of three-dimensional grating cards provided by an embodiment of the present invention, comprising: a card output channel 10 and a card cutting table 25; drive shafts 55 are rotatably provided at both ends of the card output channel 10, and the drive shafts 55 are used to drive the card output channel 10 to rotate, and at the same time, a discharging transfer vehicle 11 for collectively stacking three-dimensional grating cards is connected to the output end of the card output channel 10, and the card cutting table 25 is arranged on the side of the card output channel 10 and the top is higher than the top of the card output channel 10, and an automatic feeding device is arranged on the side of the card cutting table 25 facing the discharging transfer vehicle 11, which is used to drive the printed three-dimensional grating cards to be continuously transported toward the card cutting table 25, and the automatic feeding device is connected to the drive shaft 55 close to the side of the discharging transfer vehicle 11. When the automatic feeding device is running, it drives the drive shaft 55 to rotate, thereby driving the card output channel 10 to rotate and transport toward the discharging transfer vehicle 11, and the card cutting table 25 is away from the side wall top lifting device of the automatic feeding device. A cutting knife 26 is arranged, and elastic components are symmetrically arranged on both sides of the cutting knife 26 to ensure that the cutting knife 26 can automatically return to its initial position while being able to descend. The lower part of the side wall of the cutting knife 26 and the top of the side wall of the card cutting platform 25 are staggered and fitted. When the cutting knife 26 descends, the staggered force between the cutting knife 26 and the side wall of the card cutting platform 25 is applied, and the three-dimensional grating card passing through is quickly cut. A cutting knife pressure block 30 is arranged directly above the cutting knife 26. A lifting mechanism is connected to the side of the cutting knife pressure block 30 away from the card output channel 10. The lifting mechanism is rotatably connected to the automatic feeding device. The lifting mechanism cyclically rises and falls under the operation of the automatic feeding device, and synchronously drives the cutting knife pressure block 30 to cyclically rise and fall. The maximum position of the cutting knife pressure block 30 descending reaches the height of the upper surface of the cutting knife 26. A group of L-shaped pads 38 are swingably arranged between the cutting knife pressure block 30 and the cutting knife 26. A swing power device is arranged on the side of the L-shaped pad 38 away from the cutting knife 26. The swing power device controls the L-shaped pad 38. Swing in and out between the cutting blade pressing block 30 and the cutting blade 26. When the lifting mechanism drives the cutting blade pressing block 30 to descend to the maximum position, under the action of the thickness of the L-shaped pad 38, the bottom of the cutting blade 26 passes over the upper surface of the card cutting table 25 downward, and cuts the three-dimensional grating card placed on the card cutting table 25. A card end positioning slot plate 54 is provided at the same height as the top of the card cutting table 25 at the bottom of the swing power device, and contacts and cooperates with the moving three-dimensional grating card. The card end positioning slot plate 54 is pushed by the three-dimensional grating card, and synchronously drives the swing power device to operate, thereby pushing the L-shaped pad 38 to transfer between the cutting blade 26 and the cutting blade pressing block 30, so as to achieve cutting of the three-dimensional grating card.

[0021] Among them, the three-dimensional grating card to be cut after printing is transported toward the card cutting table 25 along the automatic feeding device. When the end of the three-dimensional grating card contacts the card end positioning slot plate 54 and pushes the card end positioning slot plate 54 to control the operation of the swing power device, the L-shaped pad 38 is controlled to be transferred between the cutting knife 26 and the cutting knife pressure block 30, and then the cutting knife 26 is driven to cut the three-dimensional grating card placed on the card cutting table 25. After cutting, the three-dimensional grating card is transferred to the card output channel 10 under the action of gravity. At this time, the automatic feeding device is operated to synchronously drive the card output channel 10 to rotate, and the three-dimensional grating card is automatically input into the inside of the discharge transfer vehicle 11 for centralized stacking, so as to realize the automatic feeding, continuous cutting and automatic discharge of the three-dimensional grating card in this scheme, and the various components are closely matched to fully improve the conversion utilization rate of power.

[0022] In the embodiment of the present invention, a three-dimensional grating card support table is arranged at the front side of the automatic feeding device, so as to facilitate its stable transportation through the automatic feeding device toward the card cutting table 25, and a support sleeve rod is rotatably mounted on the driving shaft 55, and the bottom end of the support sleeve rod is fixed to the ground; the end of the L-shaped pad 38 away from the cutting knife 26 is rotatably mounted with a vertical middle rod 40, and a fixing column 42 is installed at the bottom of the middle rod 40, and a rod cap for preventing the L-shaped pad 38 from falling upwards is installed at the top of the middle rod 40, and the middle rod 40 at the bottom of the L-shaped pad 38 is fixed to the bottom of the L-shaped pad 38. The upper sliding sleeve is provided with a sleeve 39, and a sleeve spring 41 is elastically provided on the middle rod 40 between the bottom of the sleeve 39 and the top of the fixed column 42. When the L-shaped pad 38 is subjected to the thrust from the swing power device, the L-shaped pad 38 rotates around the axis of the middle rod 40, and when the L-shaped pad 38 is subjected to the downward pressure of the cutting knife pressure block 30, the sleeve 39 compresses the sleeve spring 41 downward. When the pressure of the cutting knife pressure block 30 is lost, the L-shaped pad 38 is restored to its initial height by the rebound force of the sleeve spring 41. By controlling the lifting speed of the cutting knife pressure block 30, the L-shaped pad 38 is completely inserted between the cutting knife 26 and the cutting knife pressure block 30, while driving the cutting knife 26 to fall, cutting off the three-dimensional grating card at the bottom, and then the card end positioning slot plate 54 loses the thrust, the cutting knife pressure block 30 rises, and the L-shaped pad 38 is transferred to the outside of the cutting knife 26 and the cutting knife pressure block 30.

[0023] See also Figure 8 The length of the card end positioning slot plate 54 is greater than the width of the three-dimensional grating card, and both sides are penetrated and one side is set to be open, so that the end of the three-dimensional grating card can stably enter the card end positioning slot plate 54, pushing the card end positioning slot plate 54 to move. At the same time, the inner side of the card end positioning slot plate 54 is set with the inner end horizontal and the outer end inclined, which is convenient for the three-dimensional grating card to enter and fall off after subsequent cutting.

[0024] A group of card output guide plates 61 with a right-angled triangle structure are arranged at the lower side of the area between the card end positioning groove plate 54 and the card cutting table 25. The bottom of the inclined surface of the card output guide plate 61 is placed above the top of one side of the card output channel 10. The three-dimensional grating card cut by the cutting knife 26 falls onto the card output guide plate 61 under the action of gravity, and then slides onto the card output channel 10. At the same time, a circle of baffles is installed on the top edge of the card output channel 10 away from the card output guide plate 61 to prevent the three-dimensional grating card that slides onto the card output channel 10 from falling.

[0025] As a preferred embodiment of the present invention, the automatic feeding device includes a set of feeding power mechanism mounting plates 12, the upper part of the side wall of the feeding power mechanism mounting plate 12 is provided with a rectangular opening, and a lifting block 23 is provided inside the rectangular opening in a lifting manner. The upper and lower parts of the feeding power mechanism mounting plate 12 facing the card output channel 10 are respectively provided with an upper driving wheel 15 and a lower driving wheel 14, and the lower driving wheel 14 and the upper driving wheel 15 are connected to the center of one side of the feeding power mechanism mounting plate 12. The rotating guide rod on the lower driving wheel 14 The guide rod movably passes through the side wall of the feeding power mechanism mounting plate 12 and is connected to the output shaft 18. The rotating guide rod on the upper driving wheel 15 movably passes through the lifting block 23 and is also connected to the output shaft 18. The output shaft 18 on the lower driving wheel 14 is connected to the lower servo motor 16. The output shaft 18 on the upper driving wheel 15 is connected to the upper servo motor 17. That is, by starting the lower servo motor 16 and the upper servo motor 17 to rotate in opposite directions, the three-dimensional grating card placed between the lower driving wheel 14 and the upper driving wheel 15 is driven to move toward the card cutting table 25.

[0026] The highest point of the top of the lower driving wheel 14 is in the same height as the upper surface of the card cutting table 25, so as to facilitate the horizontal and stable transportation of the input three-dimensional grating card toward the card cutting table 25. At the same time, a circle of rubber strips 24 are evenly installed on the circumferential side walls of the lower driving wheel 14 and the upper driving wheel 15. The rubber strips 24 can increase the force of the three-dimensional grating card when the lower driving wheel 14 and the upper driving wheel 15 rotate.

[0027] See also Figure 7 As a preferred embodiment of the present invention, a rod barrel 22 with an open top is installed in the middle of the top of the lifting block 23, and a rotating rod 20 is rotatably connected inside the rod barrel 22, and an anti-falling block 21 is installed at the end of the rotating rod 20 placed inside the rod barrel 22 to prevent the rotating rod 20 from falling off from the rod barrel 22, and an adjusting screw 19 is connected to the top of the rotating rod 20, and the top thread of the adjusting screw 19 passes through the top of the rectangular opening, that is, the adjusting screw 19 is manually rotated to lift and lower, and then under the rotation connection between the rotating rod 20 and the rod barrel 22, the height of the lifting block 23 is synchronously adjusted, and then the distance between the lower driving wheel 14 and the upper driving wheel 15 is adjusted, so as to facilitate the toggle feeding operation of three-dimensional grating cards of different thicknesses.

[0028] As a preferred embodiment of the present invention, the elastic component includes an extension plate 29 installed on the upper part of the two side walls of the cutting knife 26, the bottom end of the extension plate 29 is elastically connected to a spring 28, the bottom end of the spring 28 is elastically connected to a spring tube 27, one side of the spring tube 27 is installed on the adjacent side wall of the card cutting table 25 through a fixing rod, when the cutting knife 26 is subjected to downward pressure, the springs 28 on both sides are compressed toward the inside of the spring tube 27, and then cooperate with the cutting knife 26 to descend to cut the three-dimensional grating card on the card cutting table 25, after the cutting knife 26 loses the pressure of the cutting knife pressure block 30, the resilience of the spring 28 is used to control the cutting knife 26 to return to its initial height.

[0029] As a preferred embodiment of the present invention, the lifting mechanism includes a connecting rod 31 installed on the top of the cutting blade pressing block 30, and a nut 32 is connected to the end of the connecting rod 31 away from the cutting blade pressing block 30, and a vertical ball screw 33 is threadedly connected to the middle part of the nut 32, and a guide device for limiting the rotation of the nut 32 is provided on the nut 32, and a bevel gear 1 34 is installed at the bottom of the ball screw 33, and a bevel gear 2 35 is vertically meshed with one side of the bevel gear 1 34, and a rotating shaft 36 is installed in the middle part of one side of the bevel gear 2 35, and the rotating shaft 36 is connected to the output shaft 18 of the lower servo motor 16 and rotated by a transmission belt 37. When the lower servo motor 16 drives the output shaft 18 to rotate, the rotating shaft 36 is synchronously driven to rotate through the rotation connection of the transmission belt 37, and then the bevel gear 2 35 is controlled to drive the bevel gear 1 34 to rotate, thereby driving the ball screw 33 to rotate, so as to realize the cyclic lifting and lowering of the control nut 32, and then the cyclic lifting and lowering of the cutting blade pressing block 30 is synchronously driven by the connection of the connecting rod 31. Here, the transmission belt 37 is used The rotary connection drives the cutting blade pressing block 30 to cyclically rise and fall while the lower servo motor 16 is running, thereby fully improving the power utilization of the lower servo motor 16 when it is running.

[0030] A support sleeve rod fixed on the side wall of the feed power mechanism mounting plate 12 is rotatably mounted on one side of the bottom of the ball screw 33 and the rotating shaft 36 to maintain the stable rotation of the ball screw 33 and the rotating shaft 36.

[0031] As a preferred embodiment of the present invention, the swing power device includes a U-shaped bracket arranged on one side of the L-shaped pad 38, a transverse waist-shaped slide groove 49 is opened on the top of the bracket, a connecting block 60 is slidably connected in the slide groove 49, the connecting block 60 is rotatably connected to a slide rod 50 toward one side of the card output channel 10, a locking ring is installed on the other side of the connecting block 60 for limiting the sliding of the connecting block 60, the slide rod 50 is rotatably connected to one side of the card output channel 10 with a group of swing connecting rods 46 of a V-shaped structure, a card end positioning groove plate 54 is installed on the bottom of the swing connecting rod 46 toward the side of the card cutting table 25, a distance adjustment hole 47 is installed on the top of the swing connecting rod 46, a group of swing rods 43 are arranged at the same height as the distance adjustment hole 47, a plurality of rotation positioning pins 48 are evenly spaced on the side wall of the swing rod 43, the distance adjustment hole 47 is plugged with the rotation positioning pin 48, and a locking nut for stably connecting the swing rod 43 with the swing connecting rod 46 is threadedly connected at one end of the distance adjustment hole 47;

[0032] A spring plate 63 is installed on the top of the bracket at one end of the swing rod 43 away from the L-shaped pad 38. The spring plate 63 is elastically connected to the end of the swing rod 43 with a spring second 62. The elastic effect of the spring second 62 is used to keep the card end positioning slot plate 54. After receiving the thrust of the three-dimensional grating card, the swing connecting rod 46 swings synchronously, and then drives the swing rod 43 to move toward the L-shaped pad 38. At this time, the spring second 62 is stretched, and at the same time drives the end of the swing rod 43 to push the L-shaped pad 38 between the cutting knife 26 and the cutting knife pressure block 30. After the three-dimensional grating card is cut between the card end positioning slot plate 54 and the card cutting table 25, the card end positioning slot plate 54 loses the thrust. At this time, the swing rod 43 will move under the elastic effect of the spring second 62, and then the L-shaped pad 38 moves out from between the cutting knife 26 and the cutting knife pressure block 30, and then waits for the next three-dimensional grating card to contact and push with the card end positioning slot plate 54 to carry out the next round of cutting;

[0033] At this time, the elastic stretching circle of spring 2 62 is smaller than the thrust of the three-dimensional grating card on the card end positioning slot plate 54. The rotational resistance of the swing connecting rod 46 on the connecting block 60 and the rotational resistance of the end of the L-shaped pad 38 on the middle rod 40 are both extremely small, which makes it easy to utilize the thrust of the three-dimensional grating card to easily realize the swing control of the L-shaped pad 38.

[0034] As another preferred embodiment of the present invention, a group of card wrinkle pressing blocks 53 with a width greater than the three-dimensional grating card are arranged at a position on one side of the card end positioning slot plate 54 facing the card cutting table 25, and an electric telescopic rod 52 is connected to the top of the card wrinkle pressing block 53, and an L-shaped connecting rod 51 with one end installed on the connecting block 60 is connected to the top of the electric telescopic rod 52. The height of the bottom of the card wrinkle pressing block 53 from the lower three-dimensional grating card is adjusted by the electric telescopic rod 52 to fit it tightly on the upper side of the three-dimensional grating card to prevent the three-dimensional grating card from wrinkling when it is cut to a long length and is subjected to the resistance of the card end positioning slot plate 54, thereby affecting the thrust on the card end positioning slot plate 54 and damaging the three-dimensional grating card. By installing the card wrinkle pressing block 53 on the connecting block 60 through the L-shaped connecting rod 51, it is convenient for the card wrinkle pressing block 53 to move synchronously when the lateral position of the card end positioning slot plate 54 is adjusted, without affecting its anti-wrinkle operation of fitting the lower three-dimensional grating card.

[0035] The card wrinkle pressing block 53, L-shaped pad 38, and card end positioning groove plate 54 are all made of high-hardness plastic material, so that they can maintain their functions while reducing their weight, reducing damage to the three-dimensional grating card and the normal swing of the swing rod 43.

[0036] As another preferred embodiment of the present invention, a group of positioning plates 56 are slidably provided on one side of the discharge transfer vehicle 11, and a second electric telescopic rod 57 is connected to the side of the positioning plate 56 away from the card output channel 10. The second electric telescopic rod 57 is used to adjust the position of the positioning plate 56, and the size of the space for storing the three-dimensional grating cards inside the discharge transfer vehicle 11 is adjusted according to the length of the three-dimensional grating cards after cutting, so that the three-dimensional grating cards entering therein can be stably stacked;

[0037] Slide blocks 59 are symmetrically installed on both sides of the positioning plate 56. The slide blocks 59 are slidably connected to the slide rails 58 provided in the inner wall of the discharge transfer vehicle 11. The sliding of the slide blocks 59 and the L-shaped pads 38 increases the stability of the movement of the positioning plate 56.

[0038] The end of the card output channel 10 facing the discharge transfer vehicle 11 is connected with an inclined slide plate for guiding the three-dimensional grating card to be stably transported toward the inside of the discharge transfer vehicle 11 .

[0039] The above embodiment of the present invention provides an automatic discharging mechanism for three-dimensional grating cards. When in use, the printed three-dimensional grating card to be cut is moved between the lower driving wheel 14 and the upper driving wheel 15. At this time, the lower servo motor 16 and the upper servo motor 17 are simultaneously started to drive the lower driving wheel 14 and the upper driving wheel 15 to drive the three-dimensional grating card to gradually move toward the card cutting table 25 in opposite rotation. Under the rotation connection of the transmission belt 37, the rotating shaft 36 is synchronously driven to rotate, and then the bevel gear 2 35 is controlled to drive the bevel gear 1 34 to rotate, thereby driving the ball screw 33 to rotate, realizing the cyclic lifting and lowering of the control nut 32, and then through the connecting rod 31 The connection synchronously drives the cyclic lifting of the cutting knife pressing block 30, and then the three-dimensional grating card continues to make its end contact with the card end positioning slot plate 54 under the fluctuation of the lower driving wheel 14 and the upper driving wheel 15, and then pushes the swing connecting rod 46 on the top of the card end positioning slot plate 54 to swing. At this time, the length of the card end positioning slot plate 54 from the card cutting table 25 is adjusted by sliding the connecting block 60 in the slide groove 49, and the swing distance of the swing rod 43 of the card end positioning slot plate 54 is controlled by the distance adjustment hole 47 and the corresponding rotating positioning pin 48 plug-in adjustment, fully control the swing rod 43 swing control L-shaped pad 38 to enter between the cutting knife 26 and the cutting knife block 30, so that it can stably and accurately cut the three-dimensional grating card, and then the cut three-dimensional grating card falls along the card output guide plate 61 to the card output channel 10 under the action of gravity.
