DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] Please refer to Figures 1-10As shown, the centrifugal dryer with abnormal parking function includes a base 1, a shell 2 fixedly connected to the base 1, a centrifugal drum 3 arranged in the shell 2, a power motor 4 fixedly connected to the shell 2, a first rotating wheel 5 fixedly connected to an output end of the power motor 4, a first rotating shaft 6 fixedly connected to a lower end of the centrifugal drum 3, a second rotating shaft 7, a second rotating wheel 8 fixedly connected to an outer side of the second rotating shaft 7, and a connecting unit in which a plurality of first connecting plates 10 fixedly connected to an inner side of the first rotating shaft 6 are arranged in a circumferential array, a rotating plate 12 rotatably connected to a side surface of each first connecting plate 10 through a third rotating shaft 11, a torsional spring 13 sleeved on an outer side of the third rotating shaft 11, a plurality of groups of rotating blocks 14 fixedly connected to an outer side of the second rotating shaft 7 and arranged in a circumferential array, and a plurality of structure reinforcing rods 15 fixedly connected to the first connecting plates 10 and arranged in a staggered manner with the rotating blocks 14.

[0029] A clamping ring 16 is fixedly connected to an outer side of the second rotating shaft 7 and clamped with an inner wall of the first rotating shaft 6.

[0030] A soft pad 17 is fixedly connected to one side of the structure reinforcing rod 15 facing the rotating plate 12.

[0031] In actual use, the power motor 4 drives the first rotating wheel 5 to rotate, and the second rotating wheel 8 is driven to rotate by the transmission belt 9, so that the second rotating shaft 7 is driven to rotate. At this time, the rotating blocks 14 are in contact with the rotating plate 12. Due to the arrangement of the structure reinforcing rod 15 and the torsional spring 13, the rotating plate 12 cannot rotate. With the rotation of the rotating blocks 14, the rotating plate 12 rotates and drives the centrifugal drum 3 connected thereto to rotate. When emergency stop occurs, the power motor 4 does not rotate, and the centrifugal drum 3 still rotates under the action of inertia. At this time, the rotating plate 12 rotates around the third rotating shaft 11, and the centrifugal drum 3 drives the first rotating shaft 6 to rotate, and the second rotating shaft 7 does not rotate, so as not to drive the second rotating wheel 8 and the first rotating wheel 5 to rotate, thereby not affecting the connection stability between them.

[0032] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 10 A support plate 18 is fixedly connected to a side surface of the second rotating shaft 7, a rotating sleeve 19 is fixedly connected to the support plate 18, a plurality of connecting rods 20 fixedly connected to a lower end of the centrifugal drum 3 are arranged in a circumferential array, and a roller 22 is rotatably connected to an end portion of each connecting rod 20 through a fourth rotating shaft 21.

[0033] When the centrifugal drum 3 rotates, the roller 22 rotates on the rotating sleeve 19 to ensure the stability of the centrifugal drum 3.

[0034] The upper end of the support plate 18 is fixedly connected with a guide cylinder 23, and the upper end surface of the guide cylinder 23 is fixedly connected with a friction belt 24 matched with the roller 22.

[0035] The guide cylinder 23 is provided with a friction assembly.

[0036] The friction assembly comprises circumferentially arrayed grooves 101 formed in the guide cylinder 23, a moving block 102 slidably connected in the groove 101, clamping plates 103 fixedly connected on both sides of the moving block 102, clamping grooves 104 formed in the side wall of the groove 101 and matched with the clamping plates 103, guide rods 105 fixedly connected in the clamping grooves 104 and penetrating through the clamping plates 103, springs 106 for providing elastic force and connected between the lower end of the clamping plates 103 and the clamping grooves 104, and rubber friction layers 107 fixedly connected on the upper end of the moving block 102.

[0037] In actual use, the centrifugal drum 3 contacts the rubber friction layers 107 under the action of inertia, and the rubber friction layers 107 are intermittently lifted and dropped under the elastic force of the springs 106 to reduce the speed of the centrifugal drum 3 and facilitate stopping.

[0038] The above is only an example and description of the concept of the present application, and those skilled in the art can make various modifications or supplements or use similar ways to replace the described specific embodiments, as long as the modifications or supplements or replacements do not deviate from the concept of the present application or exceed the scope defined by the present application, and should belong to the protection scope of the present application.
