Abstract
The invention discloses a preservation bag conveying shaft locking structure. The structure comprises a material shaft, wherein a locking chuck, a locking sleeve and a centering sleeve are arranged on the material shaft, the locking sleeve is connected to the locking chuck in a sleeving mode, and the locking chuck is locked to the material shaft; the centering sleeve is fixed to the outer wall of the locking sleeve through a locking nut; an open groove is formed in the side wall of the locking chuck; the locking sleeve comprises a cylindrical sleeve body and an elastic deformation block; the elastic deformation block is fixed to the inner wall of a sleeve hole of the cylindrical sleeve body; an inner hole with the diameter slightly smaller than the outer wall diameter of the locking chuck is formed in the elastic deformation block. According to the scheme, the structure is simple, clamping is convenient, clamping force is uniform, working efficiency is improved, materials can be stably and rotationally fed, the preservation bag materials are evenly stressed when being pulled, it is voided that preservation bags deform and are damaged, and therefore the producing and machining quality is improved.
Description
Technical field
The present invention relates to a kind of locking mechanism is and in particular to a kind of freshness protection package transmission shaft locking mechanism.
Background technology
Plastics freshness protection package, after Bag Material molding, will carry out flat mouth, molding according to the freshness protection package of different size to fresh-keeping Bag Material
Freshness protection package, existing flat mouth equipment generally adopts flat head machine, during moulding plastics freshness protection package in flat head machine, whole piece dress
Freshness protection package material volume is wound on barrel, during flat head machine work, feeding to be completed in fresh-keeping Bag Material is with flat head machine work, and existing material
Cylinder is placed on material axle, and the rotation of barrel is unstable, thus causing the tractive discontinuity of fresh-keeping Bag Material so that freshness protection package
Material deformation and damage.
Content of the invention
For above-mentioned technical problem, the purpose of the present invention is: proposes a kind of the steady of rotation that ensure that barrel
Fixed so that the tractive uniform force of fresh-keeping Bag Material, it is to avoid the freshness protection package transmission shaft locking knot of the deformation of fresh-keeping Bag Material and damage
Structure.
The technical solution of the present invention is achieved in that a kind of freshness protection package transmission shaft locking mechanism, including material axle, institute
State setting locking chuck, lock sleeve and centring sleeve on material axle, described lock sleeve is socketed on locking chuck, locking chuck is locked
On material axle；Described centring sleeve is fixed on lock sleeve outer wall by clamping screw；Described locking chuck side wall is provided with opening
Groove.
Further improved as the present invention, described lock sleeve includes cylindrical body and elastic deformation block；Described elasticity
Deformation block is fixed on cylindrical body and covers on the inwall in hole；Described elastic deformation block forms an endoporus and is slightly less than the outer of locking chuck
Wall diameter.
Further improved as the present invention, described open slot extends internally from locking chuck end face.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
A kind of freshness protection package transmission shaft locking mechanism of the present invention program, structure is simple, convenient mounting and clamping, and clamping force uniformly, carries
High workload efficiency is it is achieved that the stable swivel feeding of material is so that the tractive uniform force of fresh-keeping Bag Material, it is to avoid fresh-keeping Bag Material
Deformation and damage, thus improving production and processing quality.
Brief description
Below in conjunction with the accompanying drawings technical solution of the present invention is described further:
Accompanying drawing 1 is a kind of structural representation of freshness protection package transmission shaft locking mechanism of the present invention；
Wherein: 1, expect axle；2nd, locking chuck；3rd, lock sleeve；4th, centring sleeve；5th, clamping screw；6th, open slot；7th, elasticity becomes
Shape block.
Specific embodiment
The present invention to be described below in conjunction with the accompanying drawings.
Accompanying drawing 1 is a kind of freshness protection package transmission shaft locking mechanism of the present invention, including material axle 1, described material axle 1 is arranged
Locking chuck 2, lock sleeve 3 and centring sleeve 4, described lock sleeve 3 is socketed on locking chuck 2, and locking chuck 2 is locked at material axle
On 1；Described locking chuck 2 side wall is provided with open slot 6；Described open slot 6 extends internally from locking chuck 2 end face；Described
Lock sleeve 3 includes cylindrical body and elastic deformation block 7；Described elastic deformation block 7 is fixed on the inwall that cylindrical body covers hole
On；Described elastic deformation block 7 forms the outer diameter that an endoporus is slightly less than locking chuck 2；When need to lock, locking chuck 2 is enclosed within
Material axle one end, lock sleeve 3 is socketed in locking chuck 2, and the elastic deformation block 7 on lock sleeve 3 and open slot 6 coordinate, using elasticity
Deformation, locking chuck 2 is locked on material axle 1, last centring sleeve 4 is fixed on lock sleeve 3 outer wall by clamping screw 5；Knot
Structure is simple, convenient mounting and clamping, and clamping force uniformly, improves work efficiency it is achieved that the stable swivel feeding of material is so that fresh-keeping Bag Material
Tractive uniform force, it is to avoid the deformation of fresh-keeping Bag Material and damage, thus improve production and processing quality.
Above-described embodiment only technology design to illustrate the invention and feature, its object is to allow person skilled in the art
Scholar will appreciate that present disclosure and is carried out, and can not be limited the scope of the invention with this, all according to the present invention
Equivalence changes or modification that spirit is made, all should cover within the scope of the present invention.
