Description
Technical field
This utility model relates to a kind of plastics membrane production equipment.Specifically, be coiling plastic foil membrane coiler on around film
Machine change of lap plug.It is particularly suited for producing on the membrane coiler of food fresh keeping membrane.
Background technology
As is well known, food fresh keeping membrane market sold is mostly to be wound on paper tube.And in process of production, be used for around
The paper tube of food fresh keeping membrane processed needs again to be enclosed within the plug of coil replacing mechanism.Coil replacing mechanism therein includes a rotating disk, a master
Axle and four plugs, there is axis hole at the center of rotating disk, and one end of main shaft is stretched into and is fixed in axis hole.Described plug is distributed on rotating disk
Surrounding and parallel with main shaft, one end of plug is all connected on the edge of rotating disk in rotatable shape.Traditional plug contains
Principal piece and secondary segment, the inner end threading of secondary segment, one end of principal piece is machined with axial screw, and principal piece is with the one of axial screw
End is screwed in secondary segment with on externally threaded one end.Due to plug principal piece with between secondary segment only with threadeding, not only the two
Between concentricity poor, and gap easily occurs between the connection end of principal piece and secondary segment, in membrane process mandrel and on paper tube
The situation of rocking easily occurs so that fold occurs in the food fresh keeping membrane being wound on paper tube, and film roll two ends are the most irregular, and product quality is relatively
Difference.Again due to plug principal piece with between secondary segment only with threadeding, either install or remove the most cumbersome.
Utility model content
Problem to be solved in the utility model is to provide a kind of membrane coiler change of lap plug.This plug, installation or removal
The most more convenient.The paper tube bracing frame using this plug carrys out coiling food fresh keeping membrane, can improve product quality.
The problems referred to above to be solved in the utility model are realized by techniques below scheme:
Membrane coiler change of lap plug of the present utility model includes principal piece and secondary segment, it is characterised in that one end of principal piece has axially
Hole.Described secondary segment is tubulose, and its that section inner chamber adjacent with principal piece is conical section inner chamber, and the outer diameter of conical section inner chamber is big
In its inner end diameter.Having connecting shaft between principal piece and secondary segment, a section of connecting shaft is the same footpath section that each spot diameter is identical, and another section is
In the least big outer conical section, in interference fit in described same footpath section stretches into the axial hole of principal piece one end and between the two.Described circular cone
Section stretches into intracavity in the conical section of secondary segment, and makes to leave between principal piece and secondary segment gap.It is positioned at linking axes one end of secondary segment with auxiliary
Have between the outer end of section for making the draw-off mechanism of locking between principal piece and secondary segment.
Further improvement of the utility model scheme is, described draw-off mechanism includes check lock lever, outside the inner end of check lock lever has
Screw thread, there is the first circumferential projection the outer end of check lock lever.Have outside circumferential step, and circumferential step on the medial surface of secondary segment outer end is interior
Footpath is more than the internal diameter of section in it, and the internal diameter outside circumferential step is adaptive with the diameter of the first circumferential projection of check lock lever.
Further improvement of the utility model scheme is, described principal piece is tubular structure.
Of the present utility model is also to include the push rod for making principal piece depart from, push rod with secondary segment with further improvement project
There is the second circumference boss outer end, the second circumference boss cylindrical has external screw thread, that section of secondary segment outside circumferential step has interior spiral shell
Stricture of vagina.During dismounting, unload check lock lever, change push rod and the second circumference boss is screwed in the female thread on secondary segment, principal piece can be made
Disengage with secondary segment.
As can be seen from the above scheme, there is axial hole due to one end of principal piece.Described secondary segment is tubulose, and it is adjacent with principal piece
That section of inner chamber be conical section inner chamber, and the outer diameter of conical section inner chamber is more than its inner end diameter.Have between principal piece and secondary segment even
Spindle, a section of connecting shaft is the same footpath section that each spot diameter is identical, and another section is interior big outer little conical section, and described same footpath section is stretched
In interference fit in entering the axial hole of principal piece one end and between the two.Described conical section stretches into intracavity in the conical section of secondary segment, and makes
Gap is left between principal piece and secondary segment.It is positioned between linking axes one end of secondary segment and the outer end of secondary segment and has for making between principal piece and secondary segment
The draw-off mechanism of locking.
During installation, first to the same footpath section of connecting shaft and principal piece with the heating one end in axial hole, and in hot state will be even
Section one end, same footpath of spindle is inserted in the axial hole of main shaft one end so that be snuggly mated to together in interference shape between the two.Then,
By draw-off mechanism, by the inside tractive in microcephaly one end of the conical section of connecting shaft, make the conical section of connecting shaft and the cone of secondary segment
Between shape section inner chamber, firm locking is together.So, not only increase the concentricity between principal piece and secondary segment, and principal piece is with auxiliary
Do not have a gap between the connection end of section, thus avoid in membrane process mandrel and on paper tube rock situation and occur, solve
The buckling problems that the food fresh keeping membrane being wound on paper tube of having determined occurs so that in good order, product quality is preferable at film roll two ends.
Due to connecting shaft one section is interior big outer little conical section again, and that section of inner chamber that secondary segment is adjacent with principal piece is conical section
The outer diameter of inner chamber and conical section inner chamber is more than its inner end diameter, during installation, by operation draw-off mechanism, by the circle of connecting shaft
The inside tractive in microcephaly one end of conical section, can make between the conical section of connecting shaft and the conical section inner chamber of secondary segment firm locking one
Rise.During dismounting, unload draw-off mechanism, change outer end with the externally threaded push rod separately joined, one twist gently, so that it may easily make connection
The conical section of axle departs from the conical section inner chamber of secondary segment, therefore, either installs or removes the most very convenient.
