Description

Film roll core support

Technical Field

The utility model belongs to the technical field of the packaging material equipment, a support is related to, especially relate to a film rolls up core support.

Background

The roll core has the characteristics of large bearing capacity, high strength, difficult deformation and the like, can effectively prevent the wound film from being damaged due to the deformation of the roll core, reduces the loss, can increase the utilization rate of the film, is corrosion-resistant and impact-resistant, and is not influenced by environmental factors such as humidity, acid and the like, so the roll core is commonly used for winding, storing and transporting various optical films, high-performance films, metal foils and high-grade paper, and the whole film is supported by the support after the film is wound by the roll core.

However, the existing film roll core support structure basically comprises a base and a support rod, the roll core support with the structure is only suitable for storing films, the films are only placed and lifted conveniently, the rotary motion can not be performed relative to the support, the roll core is not convenient to rotate and extract the films, and therefore the roll core support structure needs to be improved.

SUMMERY OF THE UTILITY MODEL

The utility model aims at only being applicable to depositing of film to current film book core support, only playing the effect of being convenient for place and lifting by crane to the film, can not make rotary motion relative to the support, be not convenient for roll up the rotation of core and the extraction of film etc. not enough, provide a film and roll up core support, can effectively solve exist not enough in the above-mentioned problem, further satisfy the user demand.

The technical scheme of the utility model: a film roll core bracket comprises a base and a support rod arranged on the base; the method is characterized in that: the utility model discloses a film roll core, including bracing piece, U type inslot, core support, axle body, spindle nose, bearing and flexible strut, the bracing piece top is equipped with U type groove, the U type inslot is equipped with a core support, it comprises axle body, spindle nose, bearing and flexible strut to roll up the core support, the spindle nose is integral type stepped shaft structure with the axle body, the spindle nose with the inner circle fixed connection of bearing, flexible strut sets up the both ends at the axle body, flexible strut comprises dead lever, screw rod and hexagon nut piece, the bottom and the bearing welded fastening of dead lever, screw rod swing joint is in the dead lever, the fixed upper end that sets up at the screw rod of hexagon nut piece is with the axle body arrange the film in roll core inside back in.

The length of the shaft head is larger than the width of the bearing, the shaft head and the inner ring of the bearing form interference fit, and the end face of the shaft head is provided with a chamfer.

The width of the U-shaped groove is slightly larger than the diameter of the bearing.

The telescopic support frames are uniformly distributed on the outer circumference of the shaft body, and the number of the telescopic support frames is not less than 3.

The diameter of the shaft body is smaller than the diameter of an outer ring of the bearing.

The utility model has the advantages that: the utility model provides a film rolls up core support, structural by the axle body, the spindle nose, bearing and flexible strut constitute jointly, novel structure, place the axle body earlier during use and roll up inside the core, make the screw rod stretch out in the dead lever through adjusting hexagon nut, the screw rod stretches out the back and rolls up the core inner wall and form the holding power, place the spindle nose in the bracing piece that has U type groove, because be equipped with the bearing on the spindle nose, consequently, whole film rolls up the core and rolls up the core support of core inside and all can make rotary motion by the relative bracing piece, the theory of operation is clear, can not only satisfy depositing and lifting by crane the demand of film, still be favorable to rolling up the rotation of core and the extraction of film, and is very convenient to use, and the demand of film.

Drawings

Fig. 1 is a schematic structural view of the present invention installed in a support rod.

Fig. 2 is a schematic sectional view in the direction of a-a in fig. 1.

In the figure: base 1, bracing piece 2, U type groove 3, spindle nose 4, bearing 5, axle body 6, dead lever 7, clear screw rod 8, hexagon nut piece 9.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

as shown in fig. 1-2, a film roll core support, including base 1, the bracing piece 2 of setting on base 1, bracing piece 2 top is equipped with U type groove 3, be equipped with a roll core support in U type groove 3, roll up a roll core support by axle body 6, spindle nose 4, bearing 5 and flexible strut, spindle nose 4 is integral type step shaft structure with axle body 6, spindle nose 4 and bearing 5's inner circle fixed connection, flexible strut sets up the both ends at axle body 6, flexible strut is by dead lever 7, screw rod 8 and hexagonal nut piece 9 constitute, the bottom and the bearing 5 welded fastening of dead lever 7, screw rod 8 swing joint is in dead lever 7, hexagonal nut piece 9 is fixed to be set up in the upper end of screw rod 8, arrange axle body 6 in inside the film roll core back, form the support between screw rod 8 and the roll core inner wall through rotatory hexagonal nut piece 9.

As shown in fig. 1-2, in the film roll core bracket, the length of a shaft head 4 is greater than the width of a bearing 5, the shaft head 4 and the inner ring of the bearing 5 form interference fit, and the end face of the shaft head 4 is provided with a chamfer; the width of the U-shaped groove 3 is slightly larger than the diameter of the bearing 5; the telescopic brackets are uniformly distributed on the outer circumference of the shaft body 6, and the number of the telescopic brackets is not less than 3; the diameter of the shaft body 6 is smaller than the diameter of the outer ring of the bearing 5.

The utility model discloses place the axle body earlier during the use and roll up inside the core, make the screw rod stretch out in the dead lever through adjusting hexagon nut, the screw rod stretches out the back and forms the holding power with rolling up the core inner wall, place the bracing piece that has U type groove with the spindle nose in, because be equipped with the bearing on the spindle nose, consequently, whole film rolls up the core and rolls up the core support of core inside and can all make rotary motion by relative bracing piece, compare with traditional roll core support, can not only satisfy depositing and lifting by crane the demand of film, still be favorable to rolling up the rotation of core and the extraction of film, high convenience is used, the demand of film processing manufacturing has further been.
