[0030] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0031] Please refer to Figures 1-4 An automatic staple loading device for a tying machine includes a base 1 and a fixed guide rail 2 that is integral with and perpendicular to the base 1. The fixed guide rail 2 is provided with a lifting guide rail 3 that can slide up and down along its own height direction. An assembly box 6 is connected to one side of the fixed guide rail 2. The assembly box 6 is provided with multiple rows of staples 5 and an elastic pushing mechanism. The elastic pushing mechanism pushes the multiple rows of staples 5 one by one into the fixed guide rail 2.

[0032] When in use, multiple rows of tacks 5 can be loaded into the assembly box 6 together. After loading, the elastic pushing mechanism pushes the multiple rows of tacks 5 one by one into the fixed guide rail 2 for use. There is no need to install them one by one, which can greatly improve the convenience of tying and avoid taking up working time due to frequent installation of tacks 5.

[0033] The fixed guide rail 2 has a nailing groove 21 on the side near the assembly box 6. The cross-section of the nailing groove 21 is larger than that of a single row of tacks 5, so that each row of tacks 5 can smoothly enter the fixed guide rail 2. Under normal conditions, the nailing groove 21 is blocked by the lifting guide rail 3. After being blocked, the tacks in the fixed guide rail 2 are ejected. When it is necessary to push the next row of tacks 5, the lifting guide rail 3 moves upward to expose the nailing groove 21. After it is exposed, the next row of tacks 5 enters the nailing groove 21. At this time, the lifting guide rail 3 moves downward to block the nailing groove 21, and the tacks can be used normally.

[0034] Please refer to Figures 5-9 The assembly box 6 includes a front housing 62 and a rear housing 61. The rear housing 61 is fixed to the fixed guide rail 2 by screws to form an integral whole. The upper surface of the rear housing 61 is provided with a notch 612 for installing the tacks 5. The elastic pushing mechanism is located between the front housing 62 and the rear housing 61. Multiple rows of tacks 5 are located between the fixed guide rail 2 and the elastic pushing mechanism.

[0035] Specifically, the elastic pushing mechanism includes a pusher 8, which has two guide protrusions 84 on both sides. The inner walls of the front housing 62 and the rear housing 61 are provided with a first guide groove 611 and a second guide groove 621 corresponding to the guide protrusions 84. The pusher 8 pushes the staples 5 by translating along the first guide groove 611 and the second guide groove 621.

[0036] In other words, the pusher 8 can cooperate with the guide groove through the guide protrusion 84 and can move along the guide groove. When the pusher 8 moves towards the fixed guide rail 2, it can push the outermost tack 5 into the fixed guide rail 2, thus realizing the push and nailing of multiple rows of tacks one by one.

[0037] To achieve elastic (automatic) push-in nailing, a mounting groove 82 is provided on one side surface of the nail pusher 8. A compressed rectangular spring 83 is provided in the mounting groove 82. The rectangular spring 83 pushes the nail pusher 8 to move towards the fixed guide rail 2 by its own tension.

[0038] In this embodiment, the rectangular spring 83 is always in a compressed state, with one end in contact with the inner wall of the assembly box 6 and the other end in contact with the inner wall of the mounting groove 82. Therefore, the pusher 8 can be moved by the elastic thrust of the rectangular spring 83 to achieve the elastic nailing effect.

[0039] In addition, in this embodiment, since the cross-section of the rectangular spring 83 is larger than that of a conventional circular spring, the rectangular spring 83 can increase the elastic contact area, making the elastic push more stable.

[0040] It is understandable that the rectangular spring 83 can also be a Z-shaped spring.

[0041] Furthermore, after all the staples 5 in the assembly box 6 have been pushed out, additional staples need to be added inside. At this time, the staple pusher 8 is close to the fixed guide rail 2. Therefore, the staple pusher 8 needs to be moved in the opposite direction to further compress the rectangular spring 83, so as to reserve space for staples (in the assembly box 6). Specifically, the assembly box 6 is provided with a slider 7 for pulling the push pin 8 to reset. The push pin 8 has a rectangular through hole 81. The slider 7 passes through the push pin 8 at the through hole 81. The slider 7 includes an integrally formed handle 71 and a connecting block 72. The handle 71 is located outside the front housing 62. The connecting block 72 is adapted to the through hole 81; that is, the connecting block 72 is inserted into the rectangular through hole 81. A reset slide groove 622 is provided between the other two second guide grooves 621. The slider 7 extends into the assembly box 6 at the reset slide groove 622. A slot 623 is provided at one end of the reset slide groove 622 (the end away from the fixed guide rail). The slot 623 is adapted to the connecting block 72.

[0042] Please refer to this again. Figure 5 and Figure 10 The specific cooperation relationship is as follows: The slider 7 extends into the assembly box 6 at the reset groove 622. After mating, the handle 71 is located outside the front housing 62, and the connecting block 72 is located in the through hole 81 of the pusher 8. At this time, when the handle 71 is held and moved left and right, the pusher 8 can be moved left and right through the connecting block 72.

[0043] Please refer to this again. Figure 3 The pusher 8 can be moved to the left by the elastic force of the rectangular spring 83 itself. When it moves to the left, the leftmost staple 5 can be pushed into the fixed guide rail 2 to realize the nailing. When all the tacks 5 have been used up and need to be replenished into the assembly box 6, the operator holds the handle 71 and moves it to the right along the reset slide 622. At this time, the rectangular spring 83 is further compressed, and the distance between the fixed guide rail 2 and the pusher 8 increases. Multiple rows of tacks 5 can be added into the assembly box 6 at the notch 612. After adding them, the handle 71 is released. After releasing the handle 71, the pusher 8 pushes the tacks 5 again through the rectangular spring 83, and so on. Multiple rows of tacks 5 can be added at one time, avoiding frequent one-by-one tack installation.

[0044] As a preferred embodiment, the pusher 8 is L-shaped and has a rounded chamfer 85 at the corner. The purpose of the rounded chamfer 85 is to smoothly insert the rivet and avoid the rivet from touching and interfering with the pusher 8.

[0045] Furthermore, to simplify the insertion of the fasteners, a recessed groove 73 is provided on the end face of the connecting block 72. An elastic fin 9 is provided in the recessed groove 73. The elastic fin 9 is wavy and convex. When the slider 7 passes through the elastic fin 9, the elastic fin 9 pushes the connecting block 72 into the slot 623.

[0046] In other words, the slider 7 (connecting block 72) can move back and forth. When the slider 7 moves forward, the connecting block 72 does not contact the slot 623. At this time, the entire slider 7 is located in the reset slide 622, which can elastically push the staple 5. When it is necessary to add staple 5 to the assembly box 6, the entire slider 7 moves to the right. After moving to the rightmost side, the connecting block 72 is pushed by the elastic fin 9, causing the connecting block 72 to move backward and be inserted into the slot 623. At this time, the operator can release the handle 71 to add the staple. After the addition is completed, press the handle 71 to deform the elastic fin 9. After pressing, the connecting block 72 is disengaged from the slot 623, and the entire assembly re-enters the reset slide 622. This avoids holding the handle when adding staples.

[0047] like Figure 12As shown, triangular positioning plates 91 are provided on both sides of the elastic fin 9. One end of the elastic fin 9 is fixed by screws, and the two sides are limited by the positioning plates 91 to prevent the elastic fin 9 from shifting and failing to achieve the pushing operation.

[0048] like Figure 11 As shown, the fixed guide rail 2 and the lifting guide rail 3 are connected by a matching L-shaped sheet metal part 4, and the fastening nail 5 is driven out between the fixed guide rail 2 and the lifting guide rail 3.

[0049] Based on the above embodiments, the top of the fixed guide rail 2 and the lifting guide rail 3 are also provided with bent sheet metal parts, and the rear top of the fixed guide rail is provided with hooks to hold the bent sheet metal parts. When in use, the hooks and bent sheet metal parts are used to limit the movement and prevent the lifting guide rail 3 from moving up and down.

[0050] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
