[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] Embodiment 1:

[0033] The present application embodiment discloses a plate feeder head wheel combination mechanism, such as Figure 1 As shown, it includes a main shaft 1, on which two sprockets 2 are fixed by key connection, and the two sprockets 2 are sleeved on the main shaft 1, and the two sprockets 2 are spaced apart along the axial direction of the main shaft 1. The sprockets 2 are fixed on the main shaft 1 by key connection, and the key connection has the characteristics of simple structure, convenient assembly and disassembly, and ability to withstand large loads, so that the connection between the sprockets 2 and the main shaft 1 is more firm, and it is not easy to get loose or damaged, thereby extending the service life of the head wheel shaft.

[0034] like Figure 1 and 2 As shown, both ends of the main shaft 1 are installed with bearing seats 3, and the bearing seats 3 include a base 31 and a bearing 32. The base 31 is installed at the end of the main shaft 1, and a threaded hole 311 is opened on the base 31, and the threaded hole 311 is screwed in with a bolt. The bearing 32 is installed in the base 31, and the main shaft 1 is inserted into the inner ring of the bearing 32. The inner side of the base 31 is installed with a mounting flange 33 by bolts, and both ends of the main shaft 1 extend into the base 31 through the mounting flange 33. When the main shaft 1 and the bearing seat 3 need to be installed, the two ends of the main shaft 1 are moved into the corresponding base 31 through the mounting flange 33, and matched with the bearing 32, so as to realize the installation of the main shaft 1 and the bearing seat 3. The mounting flange 33 can limit the main shaft 1, improve the position accuracy of the main shaft 1, and facilitate the installation of the main shaft 1 and the bearing seat 3. After the main shaft 1 and the bearing seat 3 are installed, the operator can move the bearing seat 3 so that the bearing seat 3 drives the main shaft 1 to move, so that the bearing seat 3 and the main shaft 1 are both installed on the external equipment; after moving the bearing seat 3 to the appropriate position, screw in the bolt so that the bolt is screwed into the threaded hole 311 to realize the installation of the bearing seat 3 and the main shaft 1, so as to facilitate the normal operation of the main shaft 1.

[0035] The implementation principle of the plate feeder head wheel combination mechanism of the embodiment of the present application is:

[0036] The operator installs the sprocket 2 on the main shaft 1 through a key connection, which can withstand a large load and is more firmly installed on the main shaft 1; then the main shaft 1 is moved so that both ends of the main shaft 1 pass through the mounting flange 33 and extend into the bearing seat 3, and cooperate with the bearing 32; then the bearing seat 3 is moved to a suitable position, and the bolt is screwed into the threaded hole 311 to achieve a stable installation of the bearing seat 3 and the main shaft 1, which is convenient for the normal operation of the main shaft 1.

The connecting portion 41 is sleeved on the main shaft 1; the mounting portion 42 fits the mounting flange 33, and the mounting portion 42 is fixedly mounted on the mounting flange 33 by bolts. The operator can install the mounting portion 42 on the mounting flange 33 to achieve fixed installation of the connecting portion 41, and then one end of the main shaft 1 passes through the connecting portion 41, the mounting portion 42 and the mounting flange 33 in sequence, and then extends into the base 31; the connecting portion 41 can limit the main shaft 1, reduce the possibility of the main shaft 1 being offset, and facilitate the installation of the main shaft 1 and the bearing seat 3.

[0039] like Figure 3 and 5 As shown, a fixed sleeve 5 is fixedly connected to the middle of the main shaft 1, and the fixed sleeve 5 is sleeved on the main shaft 1. The fixed sleeve 5 can improve the structural strength of the main shaft 1 and reduce the possibility of the main shaft 1 breaking. The fixed sleeve 5 is located between the two sprockets 2, and one end of the fixed sleeve 5 is in contact with the inner side of one sprocket 2, and the other end is in contact with the inner side of the other sprocket 2. Both ends of the fixed sleeve 5 are provided with a limiting groove 51, and the inner side of the sprocket 2 is fixedly connected to the limiting block 21, and the limiting groove 51 is for the limiting block 21 to be embedded. When the sprocket 2 and the main shaft 1 are installed, the movable sprocket 2 is sleeved on the main shaft 1, and the movement of the sprocket 2 can drive the movement of the limiting block 21, so that the limiting block 21 is embedded in the limiting groove 51, and the limiting groove 51 can limit the limiting block 21, thereby limiting the sprocket 2, further improving the position accuracy of the sprocket 2, and improving the connection stability of the sprocket 2 and the main shaft 1.

[0040] like Figure 3As shown, the fixed sleeve 5 is rotatably connected with a reinforcement sleeve 6, which is sleeved on the fixed sleeve 5, and the reinforcement sleeve 6 is fixedly connected with a connecting rod 61, which is used to connect with an external device. After the main shaft 1 and the bearing seat 3 are installed on the external device, the operator fixes the connecting rod 61 with the external device to fix the reinforcement sleeve 6. The reinforcement sleeve 6 can improve the structural stability of the fixed sleeve 5, thereby improving the structural stability of the main shaft 1, and limit the rotation of the fixed sleeve 5, thereby limiting the rotation of the main shaft 1, and improving the stability of the main shaft 1 when rotating.
