Description
Technical field
The utility model belongs to film production manufacture field more particularly to a kind of rolling slitter mechanism.
Background technique
Cutting machine is a kind of mechanical equipment by wide cut paper, mica tape or film dividing at a plurality of narrow material, is commonly used
Mechanical in papermaking equipment, wire and cable mica tape and printing packaging, usually it has the winding being made of core and winding chuck
Mechanism.
For core, when work, generally fixes core using gas expansion shaft, but which has the following problems: 1, core
It is expensive, every meter of about 70-90 member；2, core usage amount is big, monthly with about 1600 or so, every about 2.2 meters；3, core
Service life is short, cannot generally be used using 4-6 times, can only sell when waste paper pipe；4, there is bending, not straight etc. and ask in core
Topic, causes the film take-up at core to wrinkle；If 5, being related to the overlength core that length reaches 2.5 meters or more, core
Price is more expensive, and nonstraightness is bigger, intensity is inadequate, not can guarantee the quality of winding finished product.
In addition, the working principle of existing winding chuck is: by winding chuck high speed rotation, so that internal cam mechanism
Band movable slider ejects, and friction belt is ejected, core inner wall is blocked, to achieve the purpose that fixed paper tube.But this kind of mode exists
Following problems: 1, since frequency of use is relatively high, internal cam and spring are easily damaged, external friction leather sheath be also required to through
Often replacement, therefore repair more frequent；2, since the power that rotation generates ejects sliding block, do not have sometimes between sliding block and core tube wall
Have sufficiently large frictional force, between core tube body and sliding block be easy skid, especially winding the very heavy Shi Genghui of film weight in this way, because
This be easy to cause product quality accident and safety accident；3, since the winding chuck of cutting machine is vulnerable part, so that maintenance cost
It is very high.
Utility model content
In order to overcome the above problem, the utility model provides a kind of novel rolling slitter mechanism, mentioned above to solve
The above problem.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of rolling slitter mechanism comprising
Winding steel core and the winding chuck for being mounted on winding steel core both ends.
Wherein, winding steel core includes cylinder, is equipped with the tapered portion that can be matched with the winding chuck at both ends of the cylinder body
With keyway portion, it is also symmetrically arranged with stage portion on the inner wall of cylinder, several through-holes are also provided on the cylinder.Pass through receipts
Coil core is used cooperatively with winding chuck, so that replacement is more convenient.Original core is changed to steel core, structure is more firm
Gu it is durable, extend the service life of product；Tapered portion is set at cylinder both ends, is conducive to the insertion of winding chuck, keyway portion
Setting can cooperate with the flat key slot socket joint on winding chuck, both avoid and to have skidded.Stage portion is arranged can be to winding
Collet is effectively limited, several through-holes are opened up on cylinder, facilitates the discharge of air when winding, improves winding effect
Fruit prevents the formation of fold.Winding chuck includes ontology, which is made of positioning region, extension, cone portion and protection portion,
The positioning region is connected with extension, and cone portion is arranged between extension and protection portion, the cone portion of ontology and guarantor when work
Shield portion can put in the inner wall of winding steel core；It offers driving groove on positioning region, is set on the two sides of the cone portion and protection portion
It is equipped with flat key slot.Cone portion is set on winding chuck, when collet has abrasion, can equally clamp steel core.In winding chuck
Protection portion is arranged in front end, and steel core is fallen down when can prevent winding steel core from not clamping.Extension is set in winding chuck rear end, works as cone
When portion is worn, extension may insure that collet continues to use.Relative to mechanical expanding winding chuck, this winding chuck cost is more
It is low.Above-mentioned winding steel core and winding chuck are made of stainless steel material, can so guarantee that the intensity for winding steel core is sufficiently large,
Through working processes such as turnings, it is ensured that winding steel core is not in ask existing for the existing core such as nonstraightness, concentricity, bounce
Topic.
Further, the keyway portion is arranged on the center line of cylinder.
Further, the through-hole is provided with two groups in the axial direction of cylinder, each group of through-hole cylinder it is upper and lower, left,
The right side is respectively arranged with one.
Further, the loss of weight blind hole that oriented extension direction extends is opened up in the main body protection portion.Preferably, blind
There are four hole is uniformly distributed in protection portion.
Further, a step surface is equipped between the positioning region and extension.
The utility model the utility model has the advantages that the utility model on the one hand by the way that core is changed to steel core so that structure is more firm
Gu it is durable, the service life of product is extended, whole manufacturing cost is reduced, on the other hand by carrying out phase to winding chuck
It should improve, transmission is realized in keyway cooperation, is avoided the generation of slipping phenomenon, while reducing the frequency of maintenance, is reduced maintenance
Cost.
