DETAILED DESCRIPTION

[0031] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0032] An automatic feeding device for a punching machine includes a feeding tube 1, a feeding mechanism 5 and a feeding mechanism 6. Figure 1 -Attached Figure 5 As shown;

[0033] The unloading tube 1 is connected to the output hose of the vibration plate, and the product coming out of the vibration plate enters the unloading tube 1 through the output hose. The upper surface of the output end of the unloading tube 1 is provided with a groove 2. Figure 6 As shown, the lower surface of the output end is provided with a gate 3 corresponding to the slit 2. Figure 8 or attached Fig. 9 As shown, the gate 3 and the trough 2 are each equipped with a corresponding opening and closing switch;

[0034] The blocking mechanism 4 is arranged on the unloading rigid tube 1 for releasing the products one by one in order, wherein the blocking mechanism 4 comprises a blocking rod 41 placed on the trough 2, a blocking piece 42 cooperating with the gate 3 for opening and closing the gate 3, and a power assembly for driving the blocking rod 41 and the blocking piece 42 to rotate to realize opening and closing the trough 2 and the gate 3, one end of the blocking rod 41 is fixedly connected to one end of the blocking piece 42, that is, the blocking rod 41 and the blocking piece 42 rotate synchronously, and the blocking piece 42 is driven to rotate by the power assembly, and the blocking rod 41 rotates in the same direction with the blocking piece 42;

[0035] When the blocking rod 41 is lowered to block the product from falling from the feeding chute 2, the blocking plate 42 opens the gate 3; when the blocking plate 42 closes the gate 3 to block the product, the blocking rod 41 is lifted up to open the feeding chute 2; the products of the feeding mechanism 5 are fed one by one by the blocking rod 41 and the blocking plate, preventing the product from being blocked at the output end of the feeding hard pipe 1;

[0036] The feeding mechanism 5 includes a driving module that performs linear reciprocating motion and a feeding block 51 fixed on the driving module. The feeding block 51 is provided with a receiving groove 52 for placing products at one end of the feeding tube 1. The products output by the feeding tube 1 fall into the receiving groove 52, and are then sent to the feeding nozzle 7 of the punching machine through the driving module.

[0037] The pushing mechanism 6 is used to push the product in the receiving trough 52 into the feeding nozzle 7 of the punching machine.

[0038] As attached Figure 5 and attached Figure 6 As shown, the power assembly includes a support block 43, an articulated seat 44, a movable block 45 and a material discharge ejector rod 46. The support block 43 is used to support and tilt the material discharge tube 1 so that the product in the material discharge tube 1 is discharged downward under the action of gravity. The articulated seat 44 is fixedly connected to the support block 43 and is placed on the side of the material discharge tube 1. The movable block 45 is hinged to the articulated seat 44. One end of the material stopper sheet 42 connected to the material stopper rod 41 is fixedly connected to the articulated seat 44. The movable block 45 can rotate relative to the articulated seat 44. When the movable block 45 rotates, it drives the material stopper rod 41 and the material stopper sheet 42 to rotate together.

[0039] A reset rod 47 is fixed on the side of the support block 43 opposite to the hinge seat 44, and the other end of the blocking rod 41 is connected to the reset rod 47 via a spring 48. The unloading push rod 46 is fixed on the feeding block 51 to push the hinge seat 44 to rotate;

[0040] Specifically, in the initial stage of the blocking mechanism 4, under the action of the spring 48, the blocking rod 41 is placed on the trough 2 to intercept the product. Fig. 9 As shown, at this time, the gate 3 is in an open state; when the feeding block 51 moves to align the receiving slot 52 with the feeding nozzle 7, the material discharge push rod 46 moves forward with the feeding block 51, and the material discharge push rod 46 gradually abuts against the movable block 45 and pushes the movable block 45 to rotate. The rotation of the movable block 45 drives the blocking rod 41 to lift up to allow the product to pass, and the blocking piece 42 rotates downward to close the gate 3 and intercept the product, as shown in the attached figure. Fig.10 As shown; when the feeding block 51 retreats until the receiving groove 52 is aligned with the unloading hard tube 1, the unloading push rod 46 retreats therewith, and the blocking rod 41 moves downward under the action of the spring 48 and closes the trough 2 to intercept the product, and at the same time, the blocking piece 42 rotates with the blocking rod 41 to open the gate 3; this process is the process in which the blocking rod 41 and the blocking piece 42 cooperate with each other to intermittently intercept the product and realize the feeding and discharging of the product one by one.

[0041] Among them, the blocking piece 42 is an L-shaped structure, the lower end of the blocking piece 42 is used to be inserted into the gate 3 to realize the opening and closing of the gate 3, and the upper end of the blocking piece 42 is fixedly connected to the movable block 45 to realize the synchronous movement between the blocking rod 41, the blocking piece 42 and the movable block 45.

[0042] As attached Fig. 9 As shown, a clearance hole 451 is provided on the movable block 45 along the length direction, and one end of the material blocking rod 41 connected to the material blocking piece 42 passes through the clearance hole 451.

[0043] In the above embodiment, preferably, Figure 7As shown, the output end of the feeding hard tube 1 is also fixed with a stopper 8 and a stopper 2 9. The stopper 8 is located at the front end of the output end of the feeding hard tube 1 and is used to block the outer port of the receiving trough 52 when discharging the material. The stopper 8 can prevent the product from falling from the outer port of the receiving trough 52 when it falls from the output of the feeding hard tube 1 to the receiving trough 52. The stopper 2 9 is located on both sides of the output end of the feeding hard tube 1. When the previous product is sent to the feeding nozzle 7, the next product will fall at the same time. To the upper surface of the feeding block 51, when the outer port of the receiving trough 52 retreats, the stopper 9 prevents the product from moving with the feeding block 51 until the product on the feeding block 51 falls into the receiving trough 52; wherein, preferably, the height of the receiving trough 52 is lower than the height of the upper surface of the receiving block, and the connection between the receiving trough 52 and the upper surface of the feeding block 51 adopts an inclined structure, and the next product falls from the surface of the feeding block 51 along the feeding block 51 into the feeding block 51.

[0044] The output end of the feeding hard pipe 1 is arranged with a flat end. Figure 8 As shown, because the feeding block 51 will slightly contact the surface of the feeding block 51 during its back-and-forth movement, the product can fall directly onto the feeding block 51 .

[0045] Please refer to the attached Figure 1 and attached Figure 3 As shown, the feeding mechanism 5 includes a fixed slide groove 53, a linear guide rail 54 slidably connected to the slide groove 53, and a driving cylinder 55 for driving the linear guide rail 54 to move. The driving cylinder 55 is arranged parallel to the linear guide rail 54, and a limiting plate 56 is fixed at one end of the linear guide rail 54. The telescopic shaft of the driving cylinder 55 is fixedly connected to the limiting plate 56, and the feeding block 51 is fixed on the upper surface of the linear guide rail 54.

[0046] As attached Figure 2 As shown, the ejection mechanism 6 includes an ejection cylinder 61 and an ejector pin 62 fixedly connected to the telescopic shaft of the ejection cylinder 61, and the ejector pin 62 is arranged opposite to the feed nozzle 7 of the punching machine; when the feeding block 51 moves to align the receiving trough 52 with the feed nozzle 7 of the punching machine, the ejection cylinder 61 drives the ejector pin 62 to move forward to eject the product in the receiving trough 52 forward into the feed nozzle 7, thereby completing the automatic loading of the product.

[0047] Specific working process:

[0048] The initial state of the device is as follows Figure 1 As shown, the material receiving groove 52 is directly opposite to the lower end of the feeding hard pipe 1. At this time, the state of the material blocking mechanism 4 is as shown in the attached Fig. 9 As shown, the blocking rod 41 is lowered to intercept the product, and the blocking piece 42 opens the gate 3;

[0049] During the feeding stage, the working status of the device is as shown in the attached Figure 2As shown, under the action of the driving cylinder 55, the feeding block 51 and the material unloading push rod 46 on the feeding block 51 move with the linear guide rail 54 until the receiving groove 52 is aligned with the feeding nozzle 7 of the punching machine. During the movement of the material unloading push rod 46, it gradually abuts against the movable block 45 and pushes the movable block 45 to rotate. The rotation of the movable block 45 drives the blocking rod 41 to lift up and the blocking piece 42 to rotate downward. The trough 2 opens, and the product intercepted by the blocking rod 41 falls to the upper surface of the feeding block 51, and the blocking piece 42 closes the gate 3 to intercept the next product. At this time, the state of the blocking mechanism 4 is as shown in the attached figure. Fig.10 As shown; then the ejector cylinder 61 pushes the ejector pin 62 to push the product on the receiving trough 52 into the feed nozzle 7, completing the loading of a product;

[0050] Finally, the feeding block 51 retreats to its initial state, and the product on the surface of the feeding block 51 rolls in place on the surface of the feeding block 51 under the action of the stopper 9, until the feeding block 51 moves to the receiving trough 52 and returns to its initial position, and the product falls from the feeding block 51 into the receiving trough 52; in the process of the feeding block 51 retreating, the unloading push rod 46 retreats with the feeding block 51 and no longer abuts against the movable block 45. Under the action of the spring 48, the stopper rod 41 and the stopper sheet 42 are pulled to rotate, and the stopper sheet 42 opens the gate 3 to release the next product. At the same time, the stopper rod 41 is placed on the trough 2 to intercept the product. At this time, as shown in the attached figure Fig. 9 The above steps are continuously repeated to feed the products of the feeding mechanism 5 one by one, so that the products enter the punching machine in an orderly and efficient manner. The whole process is completed automatically without manual intervention, which effectively improves work efficiency, reduces labor costs, and improves punching accuracy.
