Described conical surface body is the tapered sleeve of hollow.Junction of the edges of two sheets of paper screw in compression conical surface body makes the tapered sleeve of hollow can produce certain elastic deformation, connection more firm.
Described tapered sleeve bus is provided with fluting.Tapered sleeve offers fluting, and junction of the edges of two sheets of paper screw in compression conical surface body makes the tapered sleeve of hollow can produce larger elastic deformation, further increases the stability of connection.
The position that described friction top connects junction of the edges of two sheets of paper screw is provided with groove, and the head recess of junction of the edges of two sheets of paper screw is in this groove.Housing screw is embedded in friction top, reduces the probability that the ubiquitous material of existing bulking machine rotates along with holding screw in final slaking district, improves the depanning ability of material, and then while guarantee end product quality, improves the output of bulking machine.
The utility model compared with prior art, has the following advantages:
Adopt the bellmouth cone match of conical surface body and main shaft, junction of the edges of two sheets of paper screw in compression connects, conical surface location, and centering precision is high, is applicable to the working condition requirement that bulking machine high speed, heavy duty and vibration frequency are high, and meets the frequent requirement exchanged of screw rod of puffing machine configuration.Cone match, improves sealing effectiveness, reduces the probability that main shaft causes because material enters corroding, extends service life, reduces maintenance and the production cost of customer equipment.When being threaded to bottom the dismounting screwed hole withstanding main shaft in junction of the edges of two sheets of paper screw screw-in dismounting screwed hole, conical surface body can being exited in the taper hole of main shaft, improve removal efficiency, reduce maintenance cost.Conical surface body adopts tapered sleeve, can produce certain elastic deformation, connection more firm when compressing and connecting.Housing screw is embedded in friction top, reduces the probability that the ubiquitous material of existing bulking machine rotates along with holding screw in final slaking district, improves the depanning ability of material, and then while guarantee end product quality, improves the output of bulking machine.
