Abstract
The invention discloses a compression mechanism for a screw rod of a bulking machine. The compression mechanism comprises a main shaft and the screw rod arranged on the outer side of the main shaft in a sleeving manner, wherein a baffling block for limiting the displacement of the axis of the screw rod is arranged at one end of the main shaft, and a compression cover for limiting the axial displacement of the screw rod is arranged at the other end of the main shaft; a cone-shaped hole is axially formed in one end, connected with the compression cover, of the main shaft, a cone surface body is inserted into the cone-shaped hole, axial semicircular detaching threaded holes are further uniformly formed in the outer side face of the cone surface body, semicircular detaching blind holes corresponding to the detaching threaded holes are uniformly formed in the inner side face of the cone-shaped hole, and the depths of the detaching threaded holes are larger than the depths of the detaching blind holes; perforation screws penetrate through the compression cover and are connected with the detaching threaded holes. When the screw rod needs to be detached, the perforation screws are screwed into the detaching threaded holes to prop against the bottoms of the detaching blind holes of the main shaft, and the cone surface body is driven to be retreated from the cone-shaped hole of the main shaft by the perforation screws, so that the compression cover of the screw rod can be detached, the structure is simple, the time and the labor are saved when the compression cover is detached, and the production efficiency is improved.
Description
Technical field
The present invention relates to the bulking machine of feed, food processing field, especially relate to a kind of screw rod of puffing machine hold-down mechanism.
Background technology
Along with the fast development of aquaculture, the feed that utilizes traditional machining mode to process, can not meet the requirement of feeding of aquaculture far away.The appearance of expanded pellet diet has promoted product quality and feeding effect greatly, has also promoted the fast development of feed bulking equipment simultaneously.Existing screw rod of puffing machine is generally connected to above main shaft by the form of screw thread, because bulking machine discharge end pressure is too large, cause material to enter thread pitch, make the dismounting of screw-pressing lid more difficult, general method for dismounting has hammering method, pull-out method, pushing method, heat to tear method, induction heating etc. open, above method all needs corresponding professional tool, draw horse, forcing press or special extracting tool, if working site does not have corresponding instrument, be difficult to disassemble, if adopt the heat method of tearing open more will note temperature control, be not so heated to main shaft, also to prevent annealing.The material that What is more enters spindle thread hole corrodes main shaft sometimes, causes thread failure, often needs to change main shaft and solves a difficult problem, has increased production cost to enterprise.
Summary of the invention
The object of the invention is the deficiency existing for prior art, provide a kind of simple in structure, convenient disassembly, the screw rod of puffing machine hold-down mechanism that maintenance cost is low.

The tapered sleeve that described conical surface body is 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 strain, connection more firm.
Described tapered sleeve be provided with fluting along bus.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 strain, has further improved the stability connecting.
The position that described friction top connects junction of the edges of two sheets of paper screw is provided with groove, and the head of junction of the edges of two sheets of paper screw is recessed in this groove.Housing screw is embedded in friction top, reduced the ubiquitous material of existing bulking machine in final slaking district the probability along with holding screw rotation, promoted the depanning ability of material, and then in ensureing end product quality, promoted the output of bulking machine.
The present invention 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 bulking machine high speed, heavy duty and the high working condition requirement of vibration frequency, and meets the requirement that screw rod of puffing machine configuration is often exchanged.Cone match, has improved sealing effectiveness, has reduced main shaft and has caused the probability corroding because material enters, and has extended service life, reduces maintenance and the production cost of customer equipment.While being threaded to the dismounting screwed hole bottom of withstanding main shaft in junction of the edges of two sheets of paper screw screw-in dismounting screwed hole, conical surface body can be exited in the taper hole of main shaft, improve removal efficiency, reduce maintenance cost.Conical surface body adopts tapered sleeve, can produce certain strain, connection more firm compressing while connecting.Housing screw is embedded in friction top, reduced the ubiquitous material of existing bulking machine in final slaking district the probability along with holding screw rotation, promoted the depanning ability of material, and then in ensureing end product quality, promoted the output of bulking machine.
