[0037] The following is combined with Figure 1-4 This application is described in further detail.

[0038] The embodiment of the present application discloses a sprocket installation device.

[0039] Reference Figure 1 and Figure 2 The mounting device includes a mounting seat 1, a sliding plate 2, a sprocket 3 and an elastic member 4. The mounting seat 1 includes a base plate 11 and a connecting plate 12. The lower end of the base plate 11 is fixedly connected to the frame of the bar feeder. The connecting plate 12 is arranged on one side of the base plate 11 and extends vertically toward the other side of the base plate 11.

[0040] The sliding plate 2 is arranged in a rectangular plate shape, and the sliding plate 2 is slidingly connected to the side of the base plate 11 away from the connecting plate 12. In this embodiment, two sliding grooves 21 are provided on the sliding plate 2, and the two sliding grooves 21 are arranged at intervals along the width direction of the sliding plate 2 and the length direction is the length direction of the sliding plate 2. The sliding plate 2 is penetrated by bolts in the sliding grooves 21 and locked to the base plate 11, so as to realize the sliding connection of the sliding plate 2 to the base plate 11. In other embodiments, the sliding connection between the sliding plate 2 and the base plate 11 can also be realized by means of a slider sliding groove structure, a linear slide rail, etc., which is not limited by the present application.

[0041] The sprocket 3 is rotatably connected to one side of the sliding plate 2 . The elastic member 4 is a spring. The elastic member 4 is disposed between the connecting plate 12 and the sliding plate 2 to drive the sliding plate 2 away from the connecting plate 12 , that is, to drive the sliding plate 2 away from the mounting seat 1 .

[0042] In actual application, the base plate 11 is fixedly connected to the frame of the bar feeder to realize that the mounting base 1 is fixedly connected to the frame 10. At this time, the connecting plate 12 is located between the two sprockets 3, and the two sprockets 3 are connected to the chain. When the chain becomes loose after long-term use, the elastic member 4 drives the sliding plate 2 to move, so that the sliding plate 2 moves away from the connecting plate 12, so as to drive the sprocket 3 on the sliding plate 2 away from the other sprocket 3, that is, the distance between the two sprockets 3 becomes larger, so that the chain returns to the tensioned state. Even if the chain becomes loose after long-term use, the stability of the chain transmission can be guaranteed.

[0043] The components of the installation device are integrated into a whole, that is, the components are installed on the base plate 11. The sprocket 3 can be installed on the frame by simply installing the base plate 11 on the frame, thereby facilitating the installation of the sprocket 3. In addition, the production materials of the installation device as a whole can be effectively reduced to save production costs.

[0044] In some embodiments, the sprocket 3 is arranged on the side of the sliding plate 2 away from the mounting seat 1, and the elastic member 4 is arranged on the side of the mounting seat 1 close to the sliding plate 2, that is, the sprocket 3 and the elastic member 4 are located on the same side of the mounting seat 1, so as to reduce the distance between the sprocket 3 and the elastic member 4 in the axial direction of the sprocket 3, which can effectively reduce the torque exerted on the elastic member 4, thereby increasing the service life of the elastic member 4.

[0045] In some embodiments, the mounting device further comprises a mounting rod 5 and an abutment nut 6, wherein the mounting rod 5 is a "T"-shaped round rod, wherein the end of the mounting rod 5 with a smaller diameter is inserted into the connecting plate 12 and is used to abut the sliding plate 2, and the abutment nut 6 is threadedly connected to the end of the mounting rod 5 close to the sliding plate 2. The elastic member 4 is sleeved on the mounting rod 5, and one end of the elastic member 4 abuts against the connecting plate 12, and the other end abuts against the abutment nut 6, so as to drive the abutment nut 6 to move toward the sliding plate 2, thereby driving the mounting rod 5 to move, so that the end of the mounting rod 5 with a larger diameter abuts against the connecting plate 12. When installing the elastic member 4, the mounting rod 5 is first inserted into the connecting plate 12, and then the elastic member 4 is sleeved on the mounting rod 5, and then the abutment nut 6 is threadedly connected to the mounting rod 5, so as to facilitate the installation and removal of the elastic member 4, so as to facilitate the maintenance or replacement of the elastic member 4. At the same time, since the elastic member 4 is sleeved on the mounting rod 5, the bending of the elastic member 4 can be avoided as much as possible, thereby improving the service life of the elastic member 4.

[0046] In some embodiments, the mounting device further comprises a locking nut 7 which is threadedly connected to the mounting rod 5 and abuts against one end of the abutting nut 6 close to the elastic member 4 to limit loosening of the abutting nut 6 and thus improve the installation stability of the abutting nut 6 .

[0047] In some embodiments, the mounting device also includes a gasket 8, which is sleeved on the mounting rod 5, and one side of the gasket 8 abuts against the elastic member 4, and the other side abuts against one end of the locking nut 7 close to the elastic member 4. When the locking nut 7 is rotated, the gasket 8 limits the direct contact between the locking nut 7 and the elastic member 4, which can minimize the wear on the elastic member 4 caused by the installation or removal of the locking nut 7.

[0048] In some embodiments, the mounting device also includes abutment block 9, which is arranged on the side of the sliding plate 2 away from the base plate 11, and the side of the mounting rod 5 close to the sliding plate 2 abuts on the abutment block 9 to achieve abutment against the sliding plate 2. Even if the thickness of the sliding plate 2 is relatively small, the abutment area of ​​the mounting rod 5 close to one end of the sliding plate 2 can be guaranteed, so that the elastic member 4 drives the movement of the sliding plate 2 to be more stable.

[0049] In some embodiments, a clearance hole 91 is opened on one side of the abutment block 9 close to the mounting rod 5, and the position of the clearance hole 91 is in the same straight line as the position of the mounting rod 5, so that the end of the mounting rod 5 is located in the clearance hole 91, so that the abutment nut 6 abuts against one side of the abutment block 9 to increase the abutment area of ​​the abutment block 9, thereby further improving the stability of the elastic member 4 driving the sliding plate 2 to move.

[0050] In some embodiments, the abutment block 9 is locked to the sliding plate 2 by bolts to achieve a detachable connection between the abutment block 9 and the sliding plate 2. In other embodiments, the abutment block 9 can also achieve a detachable connection between the abutment block 9 and the sliding plate 2 by means of snap-on, plug-in, etc., which is not limited in the present application, thereby facilitating the installation and coordination between the elastic member 4 and the mounting rod 5, and between the mounting rod 5 and the abutment block 9.

[0051] In some embodiments, the connecting plate 12 is locked to the base plate 11 by bolts so that the connecting plate 12 can be detachably connected to the base plate 11. When the elastic member 4 needs to be removed, the connecting plate 12 is removed so that the mounting rod 5 can be disengaged from the clearance hole 91, thereby facilitating the disassembly of the mounting rod 5 and the elastic member 4.

[0052] The implementation principle of this embodiment is as follows: in actual application, the base plate 11 is fixedly connected to the frame 10 of the bar feeder to realize that the mounting base 1 is fixedly connected to the frame 10. At this time, the connecting plate 12 is located between the two sprocket wheels 3, and the two sprocket wheels 3 are both connected to the chain. When the chain becomes loose after long-term use, the elastic member 4 drives the sliding plate 2 to move, so that the sliding plate 2 moves away from the connecting plate 12, so as to drive the sprocket wheel 3 on the sliding plate 2 away from the other sprocket wheel 3, that is, the distance between the two sprocket wheels 3 becomes larger, so that the chain is restored to a tensioned state. Even if the chain becomes loose after long-term use, the stability of the chain transmission can be guaranteed.

[0053] The components of the installation device are integrated into a whole, that is, the components are installed on the base plate 11. The sprocket 3 can be installed on the frame 10 by simply installing the base plate 11 on the frame 10, thereby facilitating the installation of the sprocket 3. In addition, the production materials of the entire installation device can be effectively reduced to save production costs.

[0054] The embodiment of the present application also discloses a bar feeder.

[0055] Reference Figure 3 and Figure 4 The bar feeder includes a frame 10, a chain (not marked in the figure) and the mounting device described in the above embodiment. The base plate 11 is fixedly connected to the frame 10, and the chain is connected to the sprocket 3. The elastic member 4 drives the sliding plate 2 away from the other sprocket 3 to keep the chain in a tensioned state.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
