[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-3 This utility model provides a technical solution: a special oil tank for a combing machine's cutting blade, including a housing 1, an eccentric shaft 2 installed on the housing 1, a pulley 3 fixed to the left end of the eccentric shaft 2, the pulley 3 being located outside the housing 1 and connected to an external drive mechanism, the right end of the eccentric shaft 2 being fixed to an eccentric ring 4, the eccentric ring 4 being located inside the housing 1; it also includes: a swing arm 5 installed inside the housing 1, the swing arm 5 being connected to one end of a blade rod 6, the other end of the blade rod 6 being connected to a drag angle 7, support shafts 8 being symmetrically fixed on the blade rod 6, and blades 9 being installed on the support shafts 8 by bolts; and a movable frame 10 located inside the housing 1, the movable frame 10 being located outside the eccentric ring 4.

[0022] The eccentric shaft 2 is located above the swing arm 5, and both the eccentric shaft 2 and the swing arm 5 are connected to the housing 1 by bearings. The swing arm 5 and the eccentric ring 4 are also connected by bearings. The tool bar 6 is connected to the swing arm 5 and the drag angle 7 by threads and locking sleeves. The tool bar 6 can swing at the connection point between the swing arm 5 and the drag angle 7. A reinforcing rib is also fixed to the lower end face of the tool bar 6. One end of the support rod 801 is also fixed on the support shaft 8, and the other end of the support rod 801 is fixed to the blade 9 by bolts.

[0023] When using the special oil tank for the combing machine's cutting blade, such as Figure 1As shown, the external drive mechanism drives the pulley 3 to rotate, which in turn drives the eccentric shaft 2 and the eccentric ring 4 to reciprocate. The eccentric ring 4 drives the swing arm 5 to swing back and forth, which in turn drives the cutter bar 6 and the blade 9 to swing back and forth, thus realizing the comb cutting operation (the above working principle is the working principle of the existing cutter oil tank, so it will not be described in detail). When the cutter bar 6 and the blade 9 swing back and forth at high speed, the stability of the cutter bar 6 and the blade 9 can be ensured by the support of the reinforcing rib and the support rod 801, so as to avoid the cutter bar 6 and the blade 9 from shaking or deforming.

[0024] The movable frame 10 is also equipped with a ball bearing 1001, which can roll in contact with the outer wall of the eccentric ring 4. A brush 1002 is also fixed on the movable frame 10, which can slide in contact with the eccentric ring 4. A slide rod 11 is also vertically fixed at the upper end of the movable frame 10, and the slide rod 11 passes through the box 1 and can slide up and down. One end of a spring 12 is also fixed on the movable frame 10, and the other end of the spring 12 is fixed inside the box 1.

[0025] When the device is working, such as Figures 1-3 As shown, when the eccentric ring 4 rotates, the rolling action of the ball bearing 1001 ensures the normal rotation of the eccentric ring 4. In conjunction with the action of the movable frame 10, the eccentric ring 4 can be limited to avoid polarization. When the eccentric ring 4 rotates, the action of the spring 12 can make the brush 1002 in close contact with the eccentric ring 4, thereby cleaning foreign objects from the surface of the brush 1002 and the eccentric ring 4, ensuring the surface of the eccentric ring 4 is clean, preventing foreign objects from causing the device to jam, and thus extending the service life of the device. This is the working principle of the special cutting blade oil tank of the combing machine.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
