[0047] As shown in the Figure 2 accompanying drawings, the feeding device includes:

[0048] A feeding bottom plate 20, and a plurality of parallel fixing components 30 for fixing the short strip material are fixed above the feeding bottom plate 20. In this embodiment, the feeding bottom plate 20 is a rectangular plate structure, including four limiting plates 21, and the limiting plates 21 enclose to form a rectangular groove 22 structure; There are 5 fixing components in the rectangular groove structure of this embodiment. Taking one of the fixing components 30 as an example, its structure will be described in detail as follows. As shown in theFigures 3 - 5 As shown, the fixing assembly 30 includes;

[0049] The fixed plate body 31 is provided with a receiving groove 311 extending along its length direction. The receiving groove 311 is used to fix the groove base 11. The length of the receiving groove 311 is greater than the length of the short strip. The two ends of the fixed plate body 31 are respectively provided with mounting holes 37. Two rows of horizontally arranged mounting columns 23 are provided at positions corresponding to the mounting holes 37 at both ends of the rectangular groove 22. In this embodiment, there are five mounting columns 23 in each row. The mounting holes 37 of the fixed plate body 31 cooperate with the mounting columns 23 to achieve the fixing of the fixed plate body 31 in the rectangular groove 22. The receiving groove 311 includes;

[0050] The positioning bar hole 3111 extends along the axis of the receiving groove 311, and the groove base 11 of the short strip material 10 is located in the positioning bar hole 3111. In this embodiment, the width of the positioning bar hole 3111 is the same as the width of the groove base 11, and the groove base 11 can be firmly stuck in the positioning bar hole 3111;

[0051] The fixed side plates 3112 are located on both sides of the positioning strip holes 3111, wherein the fixed side plates 3112 on one side are uniformly provided with first positioning holes 3113 corresponding to the positioning punching holes 121 along the length direction thereof;

[0052] One end of the receiving groove 311 is also connected to a front end fixing groove 312, which extends along the length direction of the fixed side plate 3112 and is connected to the receiving groove 311. An elastic member is arranged in the front end fixing groove 312. In this embodiment, the elastic member is a spring 313. One end of the spring 313 away from the receiving groove 311 is a fixed end of the spring 313.

[0053] A sliding groove 3115 parallel to the positioning strip hole 3111 is formed at one end of the fixed side plate 3112 near the front fixed groove 312. The sliding groove 3115 is arranged in a line with the first positioning hole 3113. A sliding connector 314 is arranged in the sliding groove 3115. The free end of the spring 313 is fixed to one end of the sliding connector 314. The sliding connector 314 is fixed to the first fixing member 32 and a partial positioning punching hole 121 at one end of the short strip material 10.

[0054] like Figure 6As shown, the sliding connecting member 314 has a strip-shaped structure, and a plurality of first positioning posts 3141 are uniformly arranged along its length direction. The first positioning posts 3141 cooperate with some of the positioning punching holes 121 at the front end of the short strip material 10. The first fixing member 32 is clamped with the first positioning posts to fix the front end of the short strip material 10. A connecting portion 3142 is provided at the front end of the sliding connecting member 314. In this embodiment, the free end of the spring 313 is connected to the connecting portion 3142, and the flat structure at the top of the connecting portion 3142 can prevent the free end of the spring 313 from detaching from the connecting portion 3142.

[0055] To make the short strip material flatter, in this embodiment, the short strip material 10 is always under the action of a tensile force. Some of the positioning punching holes 121 at the front end of the short strip material 10 cooperate with the first positioning posts 3141 of the sliding connecting member 314 for fixation. The length of the sliding groove 3115 is greater than the length of the sliding connecting member 314, so that the sliding connecting member 314 can slide within the sliding groove 3115, flatten the short strip material 10 and then pull the sliding connecting member 314 to the other end of the sliding groove 3115. The spring 313 is stretched and in an extended state, and the short strip material 10 is under the tensile force of the spring 313, with better flatness. Some of the positioning punching holes 121 at the other end of the short strip material 10 cooperate with the second fixing member 33 to fix the other end of the short strip material on the fixed side plate 3112 with the first positioning hole 3113.

[0056] To prevent the front end of the short strip material 10 from slipping off the first positioning posts 3141 of the sliding connecting member 314, as Figure 7 shown, the first fixing member 32 has a rectangular structure, and a plurality of fixing holes 321 adapted to the first positioning posts 3141 are provided on the bottom surface thereof. After the first positioning posts 3141 pass through the positioning punching holes 121 at the front end of the short strip material 10, the upper ends of the first positioning posts 3141 cooperate with the fixing holes 321, and the first fixing member 32 cooperates with the sliding connecting member 314 to fix the front end of the short strip material 10 on the sliding connecting member 314.

[0057] As Figure 8 shown, the second fixing member 33 also has a rectangular structure, and a plurality of second positioning posts 331 corresponding to the positioning punching holes 121 at the rear end part of the short strip material 10 are provided on its bottom surface. The second positioning posts 331 are adapted to the apertures of the positioning punching holes 121 and the first positioning holes 3113. The second positioning posts 331 pass through the positioning punching holes 121 at the rear end part of the short strip material 10 and the first positioning holes 3113 at the corresponding positions of the fixed side plate 3112 to fix the rear end of the short strip material 10.

[0058] To further ensure the flatness of the short strip material 10, a first pressing plate 34 is further provided on the positioning plate 12 of the short strip material 10, and a second pressing plate 35 is provided on the material plate 13; specifically,

[0059] AsFigure 1 As shown, the first pressing plate 34 is located on the positioning plate 12 between the first fixing member 32 and the second fixing member 33 to improve the flatness of the positioning plate 12 at the middle position of the short strip material 10 except for the two end portions. The length of the first pressing plate 34 is less than the length of the short strip material. A first elongated hole 341 extending along its length direction is formed in the first pressing plate 34, as Figure 9 shown; the second pressing plate 35 is located above the material plate 12 and is used to flatten the entire length direction of the material plate 13. A second elongated hole 351 extending along its length direction is formed in the second pressing plate 35, as Figure 10 shown; in this embodiment, there are two second elongated holes 351, and the length of the second pressing plate 35 is greater than or equal to the length of the short strip material to ensure that the entire length direction of the material plate 13 can be flattened;

[0060] To cooperate with the fixation of the first pressing plate 34 and the second pressing plate 35, a plurality of circular positioning grooves 3114 are formed on both fixing side plates 3112. A plurality of magnetic columns 36 are fixed in the positioning grooves 3114 of this embodiment. The magnetic columns 36 and the positioning grooves 3114 are in a critical fit to ensure the firm installation of the magnetic columns 36. The height of the magnetic columns 36 is consistent with the depth of the positioning grooves 3114. The first pressing plate 34 and the second pressing plate 36 are made of ferromagnetic materials. The magnetic columns 36 press the first pressing plate 34 and the second pressing plate 35 tightly against both sides of the short strip material 10 through magnetic attraction force to further flatten the short strip material;

[0061] In another embodiment, there are threads in the positioning groove, and the bottom of the fixing column has threads (not shown in the figure). The diameter of the fixing column is adapted to the widths of the first elongated hole and the second elongated hole. The fixing column and the positioning groove 3114 are in a threaded fit to ensure the firm installation of the magnetic column. After the fixing column passes through the first elongated hole 341 of the first pressing plate 34 and the second elongated hole 351 of the second pressing plate 35, it is rotated and tightened in the positioning groove to realize the fixation of the first pressing plate and the second pressing plate.

[0062] The assembly process of the feeding device in this embodiment is as follows. First, place the magnetic column 36 on the positioning groove 3114. Since the two are in a critical fit, the fixing column 36 is firmly installed. Then, connect the free end of the spring 313 to the connecting portion 3142 of the sliding connecting member 314. Place the sliding connecting member 314 into the sliding groove 3115, and fix the fixed end of the spring 313 at the front end of the sliding groove. Then, align the front end of the short strip 10 with the front end of the sliding connecting member 314 to ensure accurate alignment of the pin holes. The partial positioning punching 121 at the front end of the short strip 10 cooperates with the first positioning column 3141 of the sliding connecting member 314 for fixation, and fasten it to the first positioning column 3141 with the first fixing member 32. Next, tighten the rear end of the short strip 10 and gently press it by hand to ensure that the short strip 10 fits flatly on the fixed side plate. Then, use the second fixing member 33 to fix the rear end of the short strip 10. Finally, fix the first pressing plate 34 and the second pressing plate 35 on both sides of the short strip 10 respectively, so as to realize the flat pressing and fixation of the short strip 10. Finally, fit the mounting holes 37 of the installed fixing component with the mounting posts 23 of the feeding bottom plate 20, and repeat the above assembly process until the feeding bottom plate 20 is filled up.

[0063] Based on the above technical solution, the feeding device has a simple and reasonable structure and is easy to operate. One end of the short strip is fixed to the sliding connecting member, the short strip is tightened, and the short strip is pressed by hand to make it fit flatly on the fixed plate body. The two ends of the short strip are fixed respectively by the first fixing member and the second fixing member.

[0064] Multiple materials can be flexibly configured, and multiple short strips can be fixed at the same time, which is convenient for assembly and disassembly.

[0065] The short strip is affected by the pulling force of the elastic member and has a good fit with the fixed plate body. When multiple short strips are fed at the same time, the flatness is good and the feeding success rate is high.

[0066] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts among the various embodiments can be referred to each other.

[0067] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: still can modify the specific implementation manners of the present invention or perform equivalent replacements on some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
