Therefore, further improvement is needed. Summary of the Utility Model

[0005] The utility model provides a loading and unloading device for an anchor bolt thread rolling machine, which solves the problem in the related technology that it is not convenient to load and unload anchor bolts with different lengths.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0026] Embodiment 1

[0027] As Figures 1 to 5 shown, this embodiment proposes a feeding and discharging device for a floor bolt rolling machine, including a machine body 1. A bottom plate 2 is fixedly connected to the bottom of the machine body 1, and a housing 3 is fixedly connected to the top of the machine body 1. A baffle 4 is fixedly connected to one side of the outside of the housing 3. A connecting shell 5 is fixedly connected to the front of the machine body 1. A motor 6 is fixedly connected to one side of the connecting shell 5. The motor 6 is fixedly connected to a reciprocating lead screw 7 through an output shaft. A bearing block 8 is provided outside the reciprocating lead screw 7. The bearing block 8 is connected to the reciprocating lead screw 7 through a ball nut pair. A limiting rod 9 is fixedly connected to the bottom of the bearing block 8. A plate body 10 is fixedly connected to the top of the bearing block 8. A clamping shell 11 is fixedly connected to the bottom of the plate body 10. A spring 12 is fixedly connected to one side inside the clamping shell 11. A sliding plate 13 is fixedly connected to the outer end of the spring 12. A guiding plate 14 is fixedly connected to one side of the outside of the sliding plate 13. An installation plate 16 is fixedly installed on one side inside the housing 3. A connecting plate 17 is fixedly connected to the bottom of the installation plate 16. The connecting plate 17 extends to one side of the outside of the housing 3.

[0028] In this embodiment, the reciprocating lead screw 7 extends into the connecting shell 5 and is connected to the connecting shell 5 through a bearing. A limiting groove is provided inside the connecting shell 5, which can facilitate the support work and rotation work of the reciprocating lead screw 7.

[0029] In this embodiment, the limiting rod 9 extends into the limiting groove and is in contact with the inside of the limiting groove. The plate body 10 is set in a zigzag shape, which can facilitate the limiting rod 9 to limit the bearing block 8.

[0030] In this embodiment, the sliding plate 13 is set in an L shape, and the outer surface of the sliding plate 13 is in contact with the inside of the clamping shell 11, which can facilitate the movement of the sliding plate 13.

[0031] In this embodiment, the connecting plate 17 and the guiding plate 14 are in the same plane. The cross-section of the guiding plate 14 is trapezoidal, which can facilitate the guiding plate 14 to move under the guidance of the connecting plate 17.

[0032] In this embodiment, a fixing plate 15 is fixedly connected to one side of the connecting shell 5. One side of the fixing plate 15 is fixedly connected to one side of the outside of the machine body 1, which can facilitate the fixed connection of the fixing plate 15.

[0033] In this embodiment, a card slot 19 is formed on one side inside the baffle 4, and a through slot 20 is formed on the other side inside the baffle 4. The length of the through slot 20 is slightly shorter than that of the card slot 19, and the bolt can be supported through the card slot 19.

[0034] During use, first, the device needs to be placed on one side of the external feeding device for guiding. When it is necessary to perform the feeding work of bolts, the bolts will automatically fall into the interior of the housing 3 and roll through the slope inside the housing 3. When the bolts roll into the card slot 19 inside the baffle 4, at this time, the staff needs to turn on the motor 6. When the motor 6 is turned on, it will synchronously drive the reciprocating lead screw 7 to rotate. During the rotation of the reciprocating lead screw 7, it will synchronously drive the bearing block 8 to move reciprocally. During the reciprocal movement of the bearing block 8, it will synchronously drive the plate body 10 to move. During the movement of the plate body 10, it will synchronously drive the card shell 11 to move. During the movement of the card shell 11, it will synchronously drive the spring 12, the sliding plate 13, and the guide plate 14 to move. When the guide plate 14 contacts the connecting plate 17, at this time, the guide plate 14 will move due to the guiding of the connecting plate 17. During the movement of the guide plate 14, it will synchronously drive the sliding plate 13 to move into the card shell 11 and compress the spring 12. At this time, the sliding plate 13 and the card shell 11 will perform the work of clamping and positioning the bolts, so as to facilitate the feeding of the bolts and facilitate the subsequent thread rolling work.

[0035] Embodiment 2

[0036] As Figure 3 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that a discharge slot 18 is formed on one side inside the connecting shell 5, and the discharge slot 18 is located at the bottom of the through slot 20, which can facilitate the discharge work of the bolts.

[0037] When the bearing block 8 drives the plate body 10 to reset, at this time, the plate body 10 will synchronously drive the card shell 11, the spring 12, and the sliding plate 13 to move. During this process, the bolts after the thread rolling will be driven to move in the direction of the motor 6. If when the guide plate 14 leaves the outside of the connecting plate 17, at this time, the spring 12 will quickly stretch and drive the sliding plate 13 to move. After the sliding plate 13 moves, it will synchronously separate from the outer surface of the bolt. Since the length of the bolt in the through slot 20 is greater than the length of the bolt in the card slot 19, the bolt will fall out of the through slot 20 by its own weight and be separated through the discharge slot 18, so as to achieve the discharging work of the bolts.

[0038] 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.
