A lip type seal consisting of parts which can be easily separated and sorted by material to facilitate recycling of the parts. A lip type seal provided with a mechanism for preventing rotation of constituent parts is also provided. The lip type seal has a first lip seal member constructed from a rubber-like elastic body, a metal-made holding ring fitted and held at the first lip member without bonding, and a resin-made second lip seal member and a backup ring which are held at the holding ring by staking. The first lip seal member has a tubular section, a radial section, a seal lip, and a flange section. The holding ring has a circular tube section, a first flange section, and a second flange section, and the second lip seal member and the backup ring are held between both the first and second flange sections by staking. A protrusion is provided at a position in the circumferential direction of the first flange section of the holding ring, and the protrusion engages with the second lip seal member to prevent rotation of the second lip seal member.

To facilitate recycling and prevent rotation of constituent parts, a lip type seal has a first lip seal member constructed from a rubber-like elastic material, a metal-made retaining ring held at the first lip seal member without bonding, and a resin-made second lip seal member and a backup ring which are held at the retaining ring by caulking. The first lip seal member has a tubular portion, a radial portion, a seal lip, and a collar portion. The retaining ring has a cylinder portion, a first flange portion, and a second flange portion, and the second lip seal member and the backup ring are held between the first and second flange portions by caulking. A convex portion is provided at a position in the circumferential direction of the first flange portion, and the convex portion engages with the second lip seal member to prevent rotation of the second lip seal member.

The invention discloses a crushing detachable combined type rag cutting machine. The crushing detachable combined type rag cutting machine includes a crushing type rag cutting machine and a detachable type rag cutting machine, wherein the crushing type rag cutting machine and the detachable type rag cutting machine are connected through through-holes. The crushing type rag cutting machine is internally provided with rag cutting rollers, a cylinder surface of each rag cutting roller is provided with rag cutting blades, and the rag cutting rollers are internally provided with rotating shafts; two sides of the crushing type rag cutting machine are provided with a first air blower and a second air blower respectively; a crushing type rag cutting machine discharge pipe is arranged on the bottom of the crushing type rag cutting machine; and the crushing type rag cutting machine and the crushing type rag cutting machine discharge pipe are connected through a crushing type rag cutting machine valve. The crushing detachable combined type rag cutting machine combines the crushing type rag cutting machine with the detachable type rag cutting machine, and can meet different rag cutting requirements during textile processing; through combination of the crushing type rag cutting machine and the detachable type rag cutting machine, the efficiency of rag cutting can be effectively improved; and the crushing type rag cutting machine and the detachable type rag cutting machine are connected through the through-holes, so that two kinds of rag cutting can be performed at the same time, and the rag cutting is more thoroughly.
