[0002] Staples are often used to organize paper documents. Staples are used to neatly bind documents together to prevent them from being scattered or lost, making it easier to archive large amounts of documents. During the processing of staples, a flattening device is required to crush the raw material (steel wire) of the staples. After the steel wire is flattened, it is reeled up for subsequent processing.

[0003] However, in the actual rolling process of the steel wire, the rolled steel wire needs to be rolled, and a roll of steel wire is usually several hundred meters long. In order to ensure the accuracy of the steel wire flattening, multiple sets of rolling rollers are generally set up for rolling, but this invisibly increases the size of the equipment and increases the manufacturing cost; and the rolling roller of the steel wire will have a problem of greater wear when rolling the steel wire, and once the surface of the rolling roller is worn, the entire rolling roller needs to be replaced. At the same time, the wear of the rolling roller is generally not discovered in the first time, which will cause the overall rolling uniformity and accuracy of the processed steel wire to decrease, and the steel wire needs to be reworked, etc., which seriously affects the rolling efficiency and quality of the steel wire.

Detailed implementation manners

[0026] The present utility model will be further described below in conjunction with the accompanying drawings and specific implementation manners:

[0027] In the description of this specification, the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or unit referred to must have a specific direction, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0028] As Figures 1 to 7 shown, a stapler flattening device includes a plurality of supports 1, the supports 1 are detachably mounted on the bottom plate 4, and a plurality of groups of rolling rollers 2 are arranged on the supports 1. The plurality of groups of rolling rollers 2 are annularly distributed, and a steel wire is transported and rolled on the rolling rollers 2, that is, by arranging a plurality of groups of annular rolling rollers 2, the steel wire can be transported and rolled along the annularly arranged rolling rollers 2.

[0029] One side of the bracket 1 is provided with a placing rack 3. The placing rack 3 is detachably installed on the bottom plate 4. A wire pay-off roller 32 and a wire take-up roller 33 are rotatably installed on the placing rack 3. The wire pay-off roller 32 is wound with the wire to be flattened, and the wire take-up roller 33 is used to collect the flattened and formed wire.

[0030] The placing rack 3 is provided with placing grooves 31 adapted to the wire pay-off roller 32 and the wire take-up roller 33. The opening size of the placing groove 31 is large and the inward extension size gradually decreases. The wire pay-off roller 32 and the wire take-up roller 33 are rotatably arranged in the placing groove 31. The opening of the placing groove 31 is arranged on the side facing away from the rolling roller 2 to facilitate the placement and removal of the wire pay-off roller 32 and the wire take-up roller 33.

[0031] A plurality of rolling grooves 211 are axially formed in the rolling roller 2. It can be understood that the plurality of rolling grooves 211 are spaced along the width direction on the outer periphery of the rolling roller 2. Each rolling groove 211 on each rolling roller 2 can be used to roll the wire to flatten the wire to the required size and shape.

[0032] Further, an offset plate 12 is arranged between two adjacent rolling rollers 2. An inclined groove 121 is formed in the offset plate 12. One end of the inclined groove 121 faces one of the rolling grooves 211, and the other end of the inclined groove 121 extends towards the rolling groove 211 in the next axial direction.

[0033] Reference Figures 1 to 3 、 Figure 5 As shown, the wire rolled and conveyed on the rolling groove 211 is guided to the rolling groove 211 in the next axial direction through the inclined groove 121. Then, the wire output from the wire pay-off roller 32 is first input into the outermost rolling groove 211. After that, the rolling roller 2 rotates to roll the wire. Subsequently, the wire is obliquely guided to the rolling groove 211 in the next axial direction through the inclined groove 121. Then, the wire is rolled in a circle by the annularly arranged rolling roller 2, and is again guided to the next rolling groove 211 through the inclined groove 121. Then, the wire is successively and circularly rolled until the wire is rolled to the other outermost rolling groove 211, and finally the rolled and formed wire is output and wound around the wire take-up roller 33.

[0034] Further, the size and shape of the rolling grooves 211 axially formed gradually decrease. When the wire is guided into the rolling groove 211 in the next axial direction through the inclined groove 121, the size of the rolling groove 211 will be smaller than that of the previous rolling groove 211 (the rolling grooves 211 in the same circle can be called the same rolling groove 211) so as to gradually roll the wire and process it into the final required size and shape.

[0035] Furthermore, the steel wire can be repeatedly rolled by the annularly distributed rolling rollers 2 to achieve the flattening operation of the steel wire. By rolling the steel wire through multiple rolling grooves 211, the uniformity and precision of the flattened steel wire are greatly increased. Moreover, through the design of annular multi-channel rolling of the steel wire, the volume and cost of the equipment are significantly reduced.

[0036] When a certain rolling groove 211 is worn, the multiple annularly distributed rolling grooves 211 cooperate with each other for rolling to make up for the problem of uneven rolling of the steel wire caused by the wear of a certain rolling groove 211, ensuring the reliability and efficiency of the steel wire processing.

[0037] Furthermore, the rolling roller 2 includes a rolling tube 21 and end components 26. The two end components 26 are located at both ends of the rolling roller 2. The number of the rolling tubes 21 is multiple and they can be assembled axially with each other.

The rolling groove 211 is formed on the outer circumference of the rolling tube 21, and one rolling groove 211 is correspondingly arranged for each rolling tube 21.

[0038] One end of the rolling tube 21 is provided with a clamping groove 22, and the clamping groove 22 is arranged in a cross shape. The other end of the rolling tube 21 is provided with a convex block 23 adapted to the clamping groove 22. By inserting the convex block 23 into the clamping groove 22, the deflection between the two rolling tubes 21 is avoided, ensuring the reliability of the rotation of the whole rolling roller 2.

[0039] The rolling tube 21 is provided with an axially penetrating connection hole 24, and the connection hole 24 connects two adjacent rolling tubes 21 through a bolt 25. By connecting and fixing two adjacent rolling tubes 21 through the bolt 25, the assembly of multiple rolling tubes 21 is realized. By setting the rolling roller 2 into a structure where multiple rolling tubes 21 are assembled with each other, when a certain rolling groove 211 is worn, the rolling roller 2 can be repaired by disassembling and replacing a new rolling tube 21, thereby reducing the maintenance cost of the equipment and improving the repair efficiency.

[0040] The end component 26 is also provided with a clamping groove 22 or a convex block 23 structure adapted to the adjacent rolling tube 21, and is installed with the rolling tube 21 through a bolt 25 to realize the assembly of the rolling tube 21 and the end component 26 into the rolling roller 2.

[0041] On the bracket 1, an inlet plate 11 corresponding to the wire pay-off roller 32 and a guide plate 132 corresponding to the wire take-up roller 33 are provided. The inlet plate 11 is installed on the bracket 1 closest to the placement rack 3, and the guide plate 132 is arranged above the same bracket 1 as the inlet plate 11.

[0042] The inlet plate 11 is provided with an inlet hole 111 corresponding to the position of the rolling groove 211. The inlet hole 111 guides the steel wire output from the wire pay-off reel 32, so that the steel wire can be stably conveyed into the rolling groove 211 for rolling.

[0043] The guide plate 132 is provided with an outlet hole 133 corresponding to the position of the wire take-up reel 33. The outlet hole 133 guides the output of the rolled steel wire. The guide plate 132 is arranged between the wire take-up reel 33 and the rolling roller 2. The guide plate 132 can reciprocate along the axial direction of the wire take-up reel 33, so that the steel wire guided by the outlet hole 133 can be wound more evenly on the wire take-up reel 33.

[0044] Specifically, the bracket 1 is provided with a mounting plate 13. The mounting plate 13 is provided with a sliding groove 131. The length direction of the sliding groove 131 is parallel to the axial direction of the wire take-up reel 33. The guide plate 132 is slidably mounted in the sliding groove 131, and the movement of the guide plate 132 is guided by the sliding groove 131.

[0045] Furthermore, a lead screw 134 and a driving member 135 are installed on the mounting plate 13. The driving member 135 can be a motor. The output end of the driving member 135 is connected to the lead screw 134. The guide plate 132 is connected to the lead screw 134. The lead screw 134 rotates to drive the guide plate 132 to reciprocate, so as to realize the reciprocating guiding of the steel wire output by the guide plate 132.

[0046] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
