Technical Field

[0001] The utility model relates to the field of nail making equipment, in particular to a feeding device for a nail making machine. Background Art

[0002] The nail making machine is mainly divided into four steps: wire drawing. Both scrap steel wire and new steel wire can be used for wire drawing. Wire drawing of scrap steel wire is more troublesome and not as fast as new steel wire, but the cost profit of scrap steel wire is very objective. The finished wire drawing is faster, which saves some manpower and the speed of nail production is also very fast.

[0003] The patent document with application number: CN202122281945.3 discloses a fast feeding device for a nail making machine, which includes a rotating sleeve, the lower end of which is rotatably arranged on the upper side of the base plate through a bearing, and the upper end of the rotating sleeve is rotated through the mounting bracket and the rotating seat through the bearing, and is fixedly arranged on the bottom surface of the rotating plate; the lower end of the limit column is inserted in the middle part of the rotating sleeve after moving through the rotating plate and the rotating seat; the No. 1 electric push rod is vertically arranged inside the rotating sleeve, and the upper end of the No. 1 electric push rod is fixedly connected to the lower end of the limit column; the driven gear is fixedly sleeved on the outer side wall of the rotating sleeve; the output end of the No. 1 motor is fixedly connected with a driving gear, and the driving gear is meshed with the driven gear; the steel wire stabilizing guide mechanism is arranged on the mounting bracket on one side of the rotating plate, which can ensure the stability of the steel wire during feeding, and at the same time, can unwind and transmit the steel wire roll.

[0004] From the above content, it can be seen that the current nail making machine needs to unwind the wire coil during the production process, and the height of the existing wire unwinding mechanism is fixed and cannot be adjusted, which causes the wire to be in a bent state during the wire feeding process, which is not conducive to the subsequent wire straightening work. Therefore, it is necessary to improve such a structure to overcome the above defects. Utility Model Content

[0023] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0024] The loading process of an existing nail making machine is usually to place the steel wire on a reel and load the material by rotating the reel. However, the height of the reel cannot be adjusted in most cases. During the unwinding process, the steel wire and the straightening mechanism are no longer parallel, which leads to a decrease in straightening efficiency and affects the subsequent production and processing of the screws.

[0025] Example 1

[0026] like Figures 1 to 4As shown, the utility model proposes a fast feeding device for a nail making machine, including a mounting bracket 1, a plurality of guide sleeves 2 on the four corners of the mounting bracket 1, guide rods 3 are arranged in the plurality of guide sleeves 2, the top of the guide rod 3 is connected to the fixed plate 4, a frame 5 is arranged below the fixed plate 4, and also includes a driving member 6 arranged inside the frame 5, the output shaft of the driving member 6 is fixedly connected to the bottom of the mounting bracket 1, the height of the unwinding mechanism can be changed by the driving member 6, the unwinding mechanism is arranged on the top of the mounting bracket 1, and a straightening mechanism is arranged on one side of the unwinding mechanism, and the length of the guide rod 3 is greater than the length of the unwinding disk 11.

[0027] There are two driving members 6. In the present embodiment, the driving members 6 are air cylinders. The staff pushes the mounting bracket to move along the length direction of the guide rod through the air cylinder, thereby changing the height of the unwinding mechanism provided on the mounting bracket, so that the unwinding steel wire and the straightening mechanism are kept at the same height, avoiding the steel wire from being in a bending state during the feeding process, and facilitating the subsequent straightening mechanism to straighten the steel wire.

[0028] The unwinding mechanism is used to unwind the steel wire, and comprises an unwinding motor 7, a driving gear 8, a driven gear 9, a transmission belt 10, and an unwinding disk 11. The bottom of the unwinding motor 7 is fixed on the mounting bracket 1, and the output end of the unwinding motor 7 is connected to the driving gear 8. The driven gear 8 is mounted on the bottom of the unwinding disk 11. The driving gear 8 and the driven gear 9 are connected by a transmission belt 10. The unwinding disk 11 is provided with steel wire. When in use, the unwinding motor 7 drives the driving gear 8 to rotate at the same time, and drives the driven gear 9 and the unwinding disk connected to the driven gear 9 to rotate through the transmission belt 10, thereby unwinding the steel wire.

[0029] The straightening mechanism is used to straighten the steel wire, which includes a straightening bracket 12, a straightening plate 13, a straightening wheel 14, a mounting block 15, a positioning block 16, and an adjusting screw 17. The straightening plate 13 is arranged on the straightening bracket 12, and a mounting groove for accommodating the mounting block 15 and the positioning block 16 is opened on the straightening plate 13.

[0030] Example 2

[0031] It also includes a straightening motor 18, in which one straightening wheel 14 is connected to the output end of the straightening motor 18, and the straightening motor 18 drives the straightening wheel 14 to rotate to guide the steel wire through the straightening mechanism. Except for the above-mentioned settings, the remaining structures are the same as those in Example 1.

[0032] The use process and principle of the utility model are as follows: the steel wire is set on the unwinding drum 11, one end of the steel wire passes through the straightening wheels 14 on the straightening mechanism, and then the unwinding motor 7 is started to drive the driving gear 8 to rotate, and the driven gear 9 and the unwinding drum connected to the driven gear 9 are driven to rotate through the transmission belt 10 to unwind the steel wire, and the straightening motor 18 drives the straightening wheel 14 to rotate, and guides the steel wire to pass through the straightening wheel 14. In this process, the staff can change the height of the unwinding drum 11 through the driving member 6 so that the steel wire and the straightening wheel are at the same height.
