Abstract
It the utility model is related to a kind of change of lap plug.Specifically, be coiling plastic foil membrane coiler on change of lap plug.It includes leading portion and back segment, and leading portion links together with back segment.It is characterized in thering is inner small and outside big bellmouth or outer small interior big conical head on the connection end of leading portion, there are outer small interior big conical head or inner small and outside big bellmouth on the connection end of back segment, coordinate between the connection end of leading portion and back segment by the bellmouth and conical head in interference shape.Using this plug, in membrane process plug and paper tube thereon can be avoided the situation of rocking occur, greatly improve product quality.It is particularly suitable for use on the membrane coiler of production food fresh keeping membrane.
Description
Technical field
It the utility model is related to plastic foil membrane coiler annex.Specifically, be coiling plastic foil membrane coiler on change of lap use
Plug.It is particularly suitable for use on the membrane coiler of production food fresh keeping membrane.
Background technology
As is well known, the food fresh keeping membrane that in the market is sold all is the web-like preservative film being wound on paper tube.And producing
Cheng Zhong, it need to be enclosed on again on the plug of coil replacing mechanism for the paper tube of coiling food fresh keeping membrane.Traditional plug contains leading portion with after
Section, the inner end threading of back segment, one end of leading portion are machined with axial screw, and the one end of leading portion with axial screw is screwed in
Back segment is with externally threaded one end.Wherein, the axial screw and back segment of leading portion connection end carry the axle of externally threaded connection end
Homogeneous etc. to each spot diameter, it is in interference fits to cause the connection between the two so that the concentricity between leading portion and back segment is poor.Due to preceding
Concentricity between section and back segment is poor so that gap easily occurs between the connection end of leading portion and back segment.Once the connection of leading portion and back segment
Occurs gap between end, the situation of rocking easily occur in plug and paper tube thereon in membrane process so that the food being wound on paper tube is protected
There is fold in fresh film, and film roll both ends are very irregular, and product quality is poor.
Utility model content
Problem to be solved in the utility model is to provide a kind of change of lap plug.Using this plug, can avoid around film mistake
There is the situation of rocking in plug and paper tube thereon in journey, greatly improve product quality.
Above mentioned problem to be solved in the utility model is realized by following technical scheme：
Change of lap of the present utility model includes leading portion and back segment with plug, and leading portion links together with back segment.Before being characterized in
There are inner small and outside big bellmouth or outer small interior big conical head on the connection end of section, have outer small interior big cone on the connection end of back segment
Match somebody with somebody between the connection end of forming head or inner small and outside big bellmouth, leading portion and back segment by the bellmouth and conical head in interference shape
Close.
Further improvement of the utility model scheme is that have internal thread in the bellmouth, there is external screw thread on conical head, preceding
Coordinate between the connection end of section and back segment by the internal and external screw thread in interference shape.
Further improvement of the utility model scheme is that the leading portion is tubular structure.
Further improvement of the utility model scheme is that the leading portion and back segment are tubular structure.
Further improvement of the utility model scheme is, is easy to at least a pair on the neighbouring connection end of the leading portion is cylindrical
The plane being parallel to each other coordinated with spanner.
It is of the present utility model further improvement project be, the cross section lateral surface at the neighbouring connection end of leading portion for ease of
The polygon coordinated with spanner.
As can be seen from the above scheme, due to having inner small and outside big bellmouth or outer small interior big cone on the connection end of leading portion
Forming head, there are outer small interior big conical head or inner small and outside big bellmouth on the connection end of back segment, the depth of the bellmouth is more than
Coordinate between the connection end of the length of conical head, leading portion and back segment by the bellmouth and conical head in interference shape.Due to leading portion
Coordinate between the connection end of back segment by bellmouth and conical head in interference shape, it is concentric between leading portion and back segment so as to improve
Degree.Due to improving the concentricity between leading portion and back segment so that be less prone to gap between the connection end of leading portion and back segment.Due to preceding
Section be less prone to gap between the connection end of back segment, avoid in membrane process plug and paper tube thereon rock situation,
So that the food fresh keeping membrane being wound on paper tube is less prone to fold, film roll both ends in good order, so as to substantially increase product matter
Amount.
Brief description of the drawings
Fig. 1 is change of lap mandrel structure schematic diagram of the present utility model.
Embodiment
As shown in figure 1, change of lap of the present utility model plug includes leading portion 4 and back segment 1, leading portion 4 is connected to one with back segment 1
Rise.Wherein, inner small and outside big bellmouth 3 is machined with the connection end of leading portion 4, is machined with the connection end of back segment 1 outer small interior big
Conical head 2, the depth of the bellmouth 3 is more than the length of conical head 2, by the cone between the connection end of leading portion 4 and back segment 1
Shape hole 3 and conical head 2 are screwed together so that are coordinated between the two in interference shape.It can also be processed on the connection end of leading portion 4 outer
Small interior big conical head 2, processes inner small and outside big bellmouth 3 on the connection end of back segment 1.It is in the connection end of leading portion 4 actually
Small interior big conical head 2 outside upper processing, inner small and outside big conical head 2 is processed on the connection end of back segment 1, or in leading portion 4
It is machined with connection end on the connection end of inner small and outside big bellmouth 3, back segment 1 and is machined with outer small interior big conical head 2, optionally
Depending on.
For ease of the close connection between leading portion 4 and back segment 1, internal thread is machined with the bellmouth 3, on conical head 2
It is machined with external screw thread, is linked together between the connection end of leading portion 4 and back segment 1 by the internal and external screw thread in interference shape.
To save material and mitigating the weight of plug, the leading portion 4 is tubular structure.
To save material and mitigating the weight of plug, the back segment 1 is tubular structure.
Further to save material and mitigating the weight of plug, the leading portion 4 and back segment 1 are tubular structure.
For ease of the installation and removal of leading portion and back segment, be machined with the neighbouring connection end of leading portion is cylindrical be easy to for a pair with
The plane 5 being parallel to each other that spanner coordinates.
, can also be at the neighbouring connection end of leading portion on the lateral surface of cross section for ease of the installation and removal of leading portion and back segment
The polygon coordinated with spanner is easy in processing.
