The recovery cylinder is a cylindrical cylinder with a hollow interior and a feed port and a discharge port corresponding to the crushing box and the recovery trough are respectively arranged at the upper and lower ends. The side wall of the recovery cylinder is provided with mesh holes, and the baffle blocks the mesh holes on one side wall of the recovery cylinder.

[0007] Furthermore, the recovery drum is horizontally rotatably arranged on the frame with the axis as the rotation axis.

[0008] Furthermore, the baffle is an arc-shaped plate, and the central angle of the circle corresponding to the baffle is greater than or equal to 180°.

[0009] Furthermore, a driving motor is provided on the frame, and the driving motor is connected to the recovery drum through a transmission assembly.

[0010] Furthermore, a conical discharge hopper is provided at the bottom of the recovery cylinder, and the discharge port is located at the bottom of the conical discharge hopper.

[0011] Furthermore, the frame is provided with a wind gathering plate, and two or more wind gathering plates are enclosed to form a wind gathering channel, and the fan and the recovery cylinder are respectively located at two ends of the wind gathering channel.

[0012] The beneficial effects of the utility model are: a rotary crusher, mesh holes are opened on the wall of the recovery cylinder, the mesh hole diameter is selected according to the size of the TPU broken film pieces, and when in use, a fan is used to supply air to the side wall of the recovery cylinder from one side. Since a baffle is provided on the other side of the recovery cylinder, after the wind enters the inner cavity of the recovery cylinder from the mesh holes on one side, it will not be blown out from the mesh holes on the other side, but will be discharged downward from the discharge port. Since the recovery cylinder keeps rotating on the frame, the TPU broken film pieces on the inner wall of the recovery cylinder can be completely blown off, preventing the TPU broken film pieces from adhering to the wall of the barrel.

[0017] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0018] The utility model provides a rotary crusher which is applied to TPU broken film recovery equipment.

[0019] Please refer to Figure 1 to Figure 2 As shown, a rotary crusher of the utility model comprises:

[0020] The frame 1 is provided with a fan 11 and a baffle 12;

[0021] The recovery cylinder 2 is rotatably arranged on the frame 1 and is located between the fan 11 and the arc-shaped baffle 12. The recovery cylinder 2 is a cylindrical cylinder with a hollow interior and a feed port 21 and a discharge port 22 corresponding to the crushing box 3 and the recovery trough 4 at the upper and lower ends respectively. The side wall of the recovery cylinder 2 is provided with a mesh 23, and the baffle 12 blocks the mesh 23 on one side wall of the recovery cylinder 2.

[0022] From the above description, it can be seen that the beneficial effects of the utility model are: a rotary crusher, a mesh hole 23 is opened on the wall of the recovery cylinder 2, the aperture of the mesh hole 23 is selected according to the size of the TPU broken film, and when in use, the fan 11 is used to supply air to the side wall of the recovery cylinder 2 from one side. Since the baffle 12 is provided on the other side of the recovery cylinder 2, the wind enters the inner cavity of the recovery cylinder 2 from the mesh hole 23 on one side, and will not be blown out from the mesh hole 23 on the other side, but will be discharged downward from the discharge port 22. Since the recovery cylinder 2 rotates continuously on the frame 1, the TPU broken film on the inner wall of the recovery cylinder 2 can be completely blown off to prevent the TPU broken film from adhering to the wall of the barrel.

[0023] In an optional embodiment, the recovery drum 2 is horizontally rotatably arranged on the frame 1 with the axis as the rotation axis.

[0024] From the above description, it can be seen that a supporting structure for the horizontal rotation of the recovery drum 2 is provided on the frame 1 to ensure the smooth rotation of the recovery drum 2.

[0025] In an optional embodiment, the baffle 12 is an arc-shaped plate, and the central angle of the circle corresponding to the baffle 12 is greater than or equal to 180°.

[0026] In an optional embodiment, a driving motor 13 is provided on the frame 1, and the driving motor 13 is connected to the recovery drum 2 through a transmission assembly.

[0027] It can be seen from the above description that the driving motor 13 is used to drive the recovery drum 2 to rotate on the frame 1.

[0028] In an optional embodiment, a conical discharge hopper 24 is provided at the bottom of the recovery cylinder 2 , and the discharge port 22 is located at the bottom of the conical discharge hopper 24 .

[0029] In an optional embodiment, the frame 1 is provided with an air gathering plate 14, and two or more air gathering plates 14 enclose an air gathering channel, and the fan 11 and the recovery cylinder 2 are respectively located at two ends of the air gathering channel.

[0030] It can be seen from the above description that the wind collecting plate 14 plays a role in collecting wind.

[0031] Please refer to Figure 1 to Figure 2 As shown, the first embodiment of the utility model is: a rotary crusher, comprising:

[0032] The frame 1 is provided with a fan 11 and a baffle 12;

[0033] The recovery cylinder 2 is rotatably arranged on the frame 1 and is located between the fan 11 and the arc-shaped baffle 12. The recovery cylinder 2 is a cylindrical cylinder with a hollow interior and a feed port 21 and a discharge port 22 corresponding to the crushing box 3 and the recovery trough 4 at the upper and lower ends respectively. The side wall of the recovery cylinder 2 is provided with a mesh 23, and the baffle 12 blocks the mesh 23 on one side wall of the recovery cylinder 2.

[0034] The recovery drum 2 is horizontally rotatably arranged on the frame 1 with the axis as the rotation axis. The baffle 12 is an arc-shaped plate, and the central angle of the circle corresponding to the baffle 12 is greater than or equal to 180°. A driving motor 13 is provided on the frame 1, and the driving motor 13 is connected to the recovery drum 2 through a transmission assembly.

[0035] To sum up, the rotary crusher of the utility model has mesh holes on the wall of the recovery cylinder, and the mesh hole diameter is selected according to the size of the TPU broken film pieces. When in use, a fan is used to supply air to the side wall of the recovery cylinder from one side. Since a baffle is provided on the other side of the recovery cylinder, after the wind enters the inner cavity of the recovery cylinder from the mesh holes on one side, it will not be blown out from the mesh holes on the other side, but will be discharged downward from the discharge port. Since the recovery cylinder keeps rotating on the frame, the TPU broken film pieces on the inner wall of the recovery cylinder can be completely blown off to prevent the TPU broken film pieces from adhering to the wall of the barrel.
