Abstract

The utility model discloses a rewind shaft of a film slitter, which comprises a main shaft installed on the machine body, a reference ring and a slitting core ring, wherein the reference ring and theslitting core ring are sleeved on the main shaft, the reference ring is fixed onto one end of the main shaft through a clamp nut, isolating rings which are connected with the slitting core ring are sleeved on the main shaft, the isolating rings are arranged on two sides of the slitting core ring, and the outer diameter of the isolating rings is equal to that of the slitting core ring. By means ofthe above structure, the rewind shaft of a film slitter improves film slitting quality, shortens film adjusting time in winding, and greatly improves product quality.

Description

A kind of Scroll of film splitter

Technical field

The utility model relates to a kind of Scroll of film splitter.

Background technology

The Scroll of existing film splitter, because following problem causes cutting machine branch film rolling end face that cuts out and the axial line out of plumb of cutting the core ring, directly influence the end face planeness and the winding speed of winding core during coiling: one, the morpheme error generally occurs after the core ring is made owing to cutting, and be set with a plurality of core rings of cutting on the Scroll usually, form bigger accumulated error, the film end face that branch is cut out can not overlap with the core ring; Two, dwindle stuck on Scroll for preventing that film take-up tension force causes cutting core ring internal diameter in the cutting process, generally will cut the internal diameter of core ring makes bigger than the external diameter of Scroll, cause when cutting Scroll to beat, divide the film end face injustice that cuts out, a kind of inflatable Scroll is also arranged, be to promote bloated core by high pressure air to come swelling to cut the core ring, reach the purpose of fixedly cutting core ring and assurance and Scroll concentricity, this mode will be cut the crimp of core ring easily, add to make when cutting the core ring error to occur, be difficult to guarantee respectively to cut the concentricity after the swelling of core ring; What three, the reference rings of Scroll adopted all is the negative thread fixed form, and promptly the reference rings inwall is a male and fomale(M﹠F), and reference rings is not fully vertical with Scroll, causes reference rings to lose the benchmark function, can only play positioning function.The technician has only the maintenance number of times of increase to Scroll, could reduce the appearance of above-mentioned situation, reduces production efficiency greatly.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides that quality is cut in a kind of raising, accent film time when shorten reeling and prolong the Scroll of the film splitter in cutting machine service life greatly.

Goal of the invention of the present utility model is achieved in that a kind of Scroll of film splitter, comprise the main shaft that is installed on the body, be set in the reference rings on the main shaft and cut the core ring, described reference rings is fixed in an end of main shaft by clamp nut, it is characterized in that: be set with and cut core ring bonded assembly shading ring on the described main shaft, described shading ring is located at and is cut core ring both sides, shading ring external diameter and cut core ring external diameter and equate.

Be equipped with groove on described main shaft surface and the shading ring inwall, described groove evenly is located on main shaft surface and the shading ring inwall.

Described reference rings inwall and main shaft surface leak-tight joint make the reference plane of reference rings keep vertical with main shaft.

The utility model improves the Scroll of the film splitter of prior art, be provided with shading ring cutting core ring both sides, be adjacent two and cut between the core ring and be provided with shading ring, avoid cutting the core ring and crimp occurs, remedied and cut the accumulated error that the core endless belt comes; The inwall of reference rings is a smooth side, promptly cancels the screw thread of reference rings inwall, makes the datum end face of reference rings keep vertical with main shaft.The Scroll of the utility model film splitter by the change of said structure, has improved the cut quality of cutting machine to film, shortens the accent film time when reeling, and improves the quality of products greatly.

Description of drawings

Fig. 1 is the structural representation of the utility model most preferred embodiment;

Fig. 2 is the structural representation of main shaft;

Fig. 3 is the structural representation of shading ring.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

According to shown in Fig. 1 to 3, the Scroll of film splitter of the present utility model, comprise main shaft 1, reference rings 2 and cut core ring 3, wherein main shaft 1 is installed on the body, reference rings 2 and cut core ring 3 and all be set on the main shaft 1, reference rings 2 inwalls and main shaft 1 surperficial leak-tight joint make the reference plane of reference rings 2 keep vertical with main shaft 1.Also be set with shading ring 4 on the main shaft 1, it is fixing with reference rings 2 that the two ends of main shaft 1 are equipped with the clamp nut 5 of clamp nut 5, one ends, and the clamp nut 5 of main shaft 1 other end is fixed shading ring 4.Shading ring 4 is located at and is cut core ring 3 both sides, cuts for promptly adjacent two and is equipped with shading ring 4 between the core ring 3, has remedied a plurality of accumulated errors that core ring 3 leak-tight joints bring of cutting.Shading ring 4 adopts the high precision grinding technics and makes, and effectively raises the squareness and the right alignment of cutting core ring 3.Shading ring 4 be a bearing fit with main shaft 1, shading ring 4 external diameters and cut core ring 3 external diameters and equate that guaranteed to cut the concentricity of core ring 3 and main shaft 1, beating appears in main shaft 1 when avoiding cutting.Be equipped with groove 6 on main shaft 1 surface and shading ring 4 inwalls, this groove 6 be an arc groove, and groove 6 evenly is located at main shaft 1 surface and shading ring 4 inwalls, and the probability that reduction shading ring 4 is out of shape avoids between shading ring 4 and the main shaft 1 appearance stuck, has improved winding quality.
