A support groove with an upward-facing notch is arranged at the top of the side frame. A material shaft that can rotate therein is embedded in the support groove. A set of tensioning components are respectively arranged on the left and right sides of the moving base.

[0006] The utility model is further arranged as: The tensioning component includes a fixed spring mounting pin fixed to the chassis and a movable spring mounting pin fixed to the movable base.

[0013] In order to enable those skilled in the art to better understand the technical solutions of the utility model, the preferred implementation schemes of the utility model will be described below in conjunction with specific embodiments. However, it should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, rather than limiting the patent requirements of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the utility model.

[0014] The utility model will be further described below in conjunction with the drawings and preferred embodiments.

[0015] Embodiment 1

[0016] Referring to Figure 1 and Figure 2 As shown, a feeding device for screw preparation involved in this embodiment includes an unwinding mechanism 100, a straightening mechanism 200, and a traction mechanism 300. The straightening mechanism 200 is arranged between the unwinding mechanism 100 and the traction mechanism 300. The unwinding mechanism 100, the straightening mechanism 200, and the traction mechanism 300 are arranged horizontally in the front-rear direction. The unwinding mechanism 100 includes a chassis 1 extending horizontally left and right. A linear guide rail 2 extending horizontally in the front-rear direction is provided on the chassis 1. A movable base 3 that moves followingly is slidably connected to the linear guide rail 2. Two side frames 4 arranged symmetrically left and right are provided on the movable base 3. A support groove 5 with an upward-facing notch is provided at the top of the side frame 4. A material shaft 6 that can rotate therein is embedded in the support groove 5. A set of tensioning components are respectively provided on the left and right sides of the movable base 3.

[0017] Furthermore, the tensioning component includes a fixed spring mounting pin 7 fixed to the chassis 1 and a movable spring mounting pin 8 fixed to the movable base 3. A tension spring 9 with one end connected to the fixed spring mounting pin and the other end connected to the movable spring mounting pin is provided between the movable spring mounting pin 8 and the fixed spring mounting pin 7.

[0018] Further, circular baffles 10 are respectively arranged at both ends of the material shaft 6 near the side frame 4.

[0019] Further, a linear slider 11 is slidably connected to the linear guide rail 2, and the movable base 3 is fixed on the linear slider 11.

[0020] Further, the notch of the support groove 5 has a flared portion (not marked).

[0021] In this embodiment, the steel wire is pulled by the traction mechanism 300. Since the unwinding position of the steel wire changes in real time, during the pulling process, the material roll wound on the material shaft 6 will follow, and move laterally with a small amplitude along with the movable base 3. When the horizontal axis at the steel wire unwinding position is on the left side, during the pulling process, the movable base 3 moves to the right; when the horizontal axis at the steel wire unwinding position is on the right side, during the pulling process, the movable base 3 moves to the left. During the right or left movement of the movable base 3, it is tightened by the tensioning assembly to play a role of resetting and shock absorption.

[0022] Among them, through the setting of the circular baffle 10, it is used for the axial limit of the material shaft 6.

[0023] Among them, through the setting of the flared portion, it is convenient for the material shaft 6 to be installed in the support groove 5, playing a role of installation guidance.

[0024] The feeding device for screw preparation involved in the present utility model, by horizontally arranging the material roll and matching with a movable base that can float left and right, enables the pulled steel wire to be kept in a straight line with the straightening mechanism and the traction mechanism, with small traction resistance, low energy consumption, energy conservation and environmental protection, and the overall function is perfect and the practicability is strong.
