Description
Technical Field
[0001] The utility model relates to stapler production equipment, in particular to a metal wire conveying roller group and a stapler wire plate production line having the metal wire conveying roller group. Background Art
[0002] There are two forms of stapler production. The first is to bend a single metal wire to form multiple metal single nails, and then bond the metal single nails to obtain rows of stapler products. The second is to use multiple metal wires, convey the metal wires side by side, and bring the metal wires close to each other. Through steps such as gluing and drying, the metal wires are processed into wire boards, and then the wire boards are cut and formed to obtain stapler products.
[0003] Among them, the second method has higher production efficiency and has gradually become the mainstream stapler production method. After the metal wire is processed and drawn, the stapler needs to be further polished to remove the burrs on the surface of the single metal wire, especially the adjacent sides of the metal wire, which directly determines the tightness of the arrangement between each metal nail. When the first method is used, the single metal wire will be polished in the stapler bending equipment. When the moving metal wire passes through the stationary polishing groove, the metal wire and the polishing groove will rub against each other to achieve the polishing of the metal wire surface.
[0004] At present, in the second production method, there is no equipment for grinding the metal monofilaments, and the existing equipment for grinding metal wires is difficult to be applied to this type of staple production line.
[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] This embodiment discloses a wire conveying roller assembly, referring to Figure 1-Figure 3 As shown, it includes a conveying roller 1, an upper pressure roller 3 and a conveying roller 2. The conveying roller 1, the upper pressure roller 3 and the conveying roller 2 are respectively installed on the frame through a rotating shaft, and can roll to play a role in conveying the metal wire.
[0030] The conveying roller 1, the upper pressure roller 3 and the conveying roller 2 are arranged in sequence along the conveying direction of the metal wire, and a plurality of metal wires 6 are laid on the upper side of the conveying roller 1 and the conveying roller 2, and the upper side of the conveying roller 1 and the conveying roller 2 is for the metal wire to pass around. The upper pressure roller 3 is located on the upper side of the metal wire 6, and the lower side of the upper pressure roller 3 is for the metal wire to pass around, which plays a role of pressing down on the metal wire, and the metal wire forms a certain angle of wrapping on the lower side of the upper pressure roller 3.
[0031] In addition, a lower pressing roller 5 is installed on the lower side of the upper pressing roller 3, and the lower pressing roller 5 is located directly below the upper pressing roller 3, and a certain gap is formed between the upper pressing roller 3 and the lower pressing roller 5, and the metal wire can pass through the gap between the upper pressing roller 3 and the lower pressing roller 5. The upper pressing roller 3 and the lower pressing roller 5 press against the upper and lower sides of the metal wire, exerting a certain pressure on the metal wire to ensure that each metal wire can be laid side by side.
[0032] Reference Figure 4 As shown, at the lower side of the lower pressing roller 5, the metal wires are arranged along the axial direction of the upper pressing roller 3, and the two metal wires are in contact with each other on the side close to each other. The metal wires are closely arranged to form a wire plate structure, and the metal wires are subsequently glued and bonded to form an integral wire plate during the conveying process. Figure 1-Figure 3 In the figure, the density of the arrangement of the metal wires is only for illustration.
[0033] The conveying roller group also includes two limiting rollers 4, which are respectively a limiting roller 1 41 and a limiting roller 2 42, wherein the limiting roller 1 41 is installed between the conveying roller 1 and the upper pressure roller 3, and the limiting roller 2 42 is installed between the upper pressure roller 3 and the conveying roller 2 2. The upper and lower sides of the limiting roller 1 41 can be passed around by the metal wire, and the upper and lower sides of the limiting roller 2 42 can also be passed around by the metal wire.
[0034] Reference Figure 1 , Figure 2As shown, the metal wires arranged side by side are divided into two groups, namely metal wire 1 61 and metal wire 2 62, and metal wire 1 61 and metal wire 2 62 are arranged alternately. For example, metal wire 1 61 passes through the upper side of conveying roller 1, then passes through the upper side of limiting roller 1 41, then passes through the lower side of upper pressure roller 3, then passes through the lower side of limiting roller 2 42, and finally passes through the upper side of conveying roller 2 2; metal wire 2 62 passes through the upper side of conveying roller 1, then passes through the lower side of limiting roller 1 41, then passes through the lower side of upper pressure roller 3, then passes through the upper side of limiting roller 2 42, and finally passes through the upper side of conveying roller 2 2. The metal wire 1 61 and the metal wire 2 62 will form different conveying directions on the lower side of the upper pressing roller 3. One group of metal wires will be conveyed from top to bottom, and the other group of metal wires will be conveyed from bottom to top, forming an up and down relative displacement on the lower side of the upper pressing roller 3. Relative friction will be generated between adjacent metal wires. The edges of the metal wires can be deburred through the contact between the metal wires, making the adjacent surfaces of the metal wires smoother, which is beneficial to improving the final product quality of the staplers.
[0035] Two limiting rollers are installed on the frame and fixedly installed. They remain stationary relative to the frame and cannot rotate. The limiting rollers only play the role of limiting and diverting, and will move the two adjacent groups of metal wires to the upper sides respectively, and guide the different metal wires. The outer circumference of the limiting roller is a cylindrical structure, and the surfaces on the upper and lower sides form arc-shaped structures, so that the metal wire can form a relatively smooth movement state when it passes around. Since the limiting roller is in a stationary state, the upper and lower side surfaces of the stapler will contact the limiting rollers, forming relative friction. The upper and lower side surfaces of the metal wire can be polished through friction, thereby improving the surface smoothness of the metal wire, thereby improving the smoothness of the final staples, and improving the quality of the staples.
[0036] In order to limit the metal wire so that it can be closely arranged when it passes through the lower side of the upper pressure roller 3, the metal wire can be further guided and limited to prevent the metal wire from diffusing in the axial direction at both ends, causing the metal wire to be scattered and spaced.
[0037] Reference Figure 5 , Figure 6 As shown, a plurality of limiting fins 1 401 are fixedly connected to the upper side of the limiting roller, and each limiting fin 1 401 is evenly distributed along the axial direction of the limiting roller, and a limiting groove 1 4011 is formed between adjacent limiting fins 1 401, and each limiting groove 1 4011 is used to accommodate a metal wire. A plurality of limiting fins 2 402 are fixedly connected to the lower side of the limiting roller, and each limiting fin 2 402 is evenly distributed along the axial direction of the limiting roller, and a limiting groove 2 4021 is formed between adjacent limiting fins 2 402, and each limiting groove 2 4021 is used to accommodate a metal wire.
[0038] The distribution structures of the limiting fin 1 401 and the limiting fin 2 402 are similar to each other, and the upper and lower limiting fins are staggered and distributed, and the formed limiting groove 1 4011 and the limiting groove 2 4021 are also staggered. Two groups of metal wires pass through the limiting groove 1 4011 and the limiting groove 2 4021 respectively, and the limiting groove 1 4011 and the limiting groove 2 4021 separate the metal wires to ensure that the metal wires can be within a limited range, avoiding the situation where the metal wires are arranged too tightly or too loosely.
[0039] Specifically, along the axis direction of the limiting roller, the width of the limiting groove 4011 is greater than the width of the metal wire, and the sum of the width of the limiting groove 4011 and the width of the limiting fin 401 is equal to twice the width of the metal wire. Considering that there may be certain burrs on the surface of the metal wire in the width direction, the sum of the width of the limiting groove 4011 and the width of the limiting fin 401 may also be slightly greater than twice the width of the metal wire, and no more than 2.2 times, to avoid excessive dispersion of the metal wire.
[0040] Similarly, along the axis direction of the limiting roller, the width of the second limiting groove 4021 is greater than the width of the metal wire, and the sum of the width of the second limiting groove 4021 and the width of the second limiting fin 402 is equal to twice the width of the metal wire. Considering that there may be certain burrs on the surface of the metal wire in the width direction, the sum of the width of the second limiting groove 4021 and the width of the second limiting fin 402 may also be slightly greater than twice the width of the metal wire, and does not exceed 2.2 times.
[0041] Furthermore, in the same conveying roller, the limiting fin 1 401 is located at the middle position of the back side of the limiting groove 2 4021, and the limiting fin 2 402 is located at the middle position of the back side of the limiting groove 1 4011. The positions of the limiting groove 1 4011 and the limiting groove 2 4021 are as follows: Figure 6 state. On the upper and lower sides of the limiting roller, the metal wires can be in a uniform distribution structure. Under the guiding action of the limiting roller and the limiting fin, when the metal wire 1 61 and the metal wire 2 62 pass through the position of the upper pressure roller 3 and the lower pressure roller 5 together, the adjacent metal wires can be in basic contact with each other, and the relative friction of the contact surface between the metal wires can polish the surface of the contact side, thereby improving the smoothness of the metal wire surface and thus improving the final quality of the staples.
[0042] This embodiment also discloses a staple wire board production line, which uses the metal wire conveying roller group in the above embodiment. During the production process, the metal wires are conveyed side by side, and processed into a sheet structure through steps such as gluing and drying, that is, a semi-finished wire board in the staple production process is formed. The wire board is pressurized to obtain the final staple product.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
