Abstract
The utility model relates to carton manufacturing equipment technical fields, and in particular to a kind of polyurethane corner cut edge bearing.A kind of polyurethane corner cut edge bearing, including edge bearing main body, edge bearing main body include superficial layer, middle layer and internal layer, and three is cyclic structure, and superficial layer is sheathed on outside middle layer, and middle layer is sheathed on outside internal layer；Superficial layer is using superficial layer made of polyurethane, its both ends is respectively provided with a bulge-structure when expansion, superficial layer after circlewise, is caught in the concave configuration for being set to middle layer outer wall on middle layer outer wall after two bulge-structure splits, and concave configuration is arranged along the axial direction of middle layer.Due to the adoption of the above technical scheme, the utility model reduces the impact to becket itself when fluting portion works, and further weakens the vibration of grooved shaft, after additionally aiding corner cut, paper scrap stripping is sprung back, to allow the easier disengaging cardboard of corner cut edge grinding, keeps the cleaning in carton production.
Description
Technical field
The utility model relates to carton manufacturing equipment technical fields, and in particular to a kind of polyurethane corner cut edge bearing.
Background technique
For a long time, it is that domestic and international Carbon enterprise faces the most common technical problem that corner cut, which is not thorough,.Original corner cut work
Skill is cut using cut of the blade on becket, stick box short side needed for cutting stick box.However during the installation process due to blade
There may be not parallel and different paper grammes per square metres and corrugation thickness to distinguish, and in the production process of carton, often will appear pressure
Too small corner cut cannot be thorough, and the excessive corner cutter of pressure hits the accident of becket.Since fluting portion is accurate unit, hits and generate
Vibration can seriously damage grooved shaft service life, and destroy fluting precision, to increase the scrappage of carton.
Utility model content
The purpose of the utility model is to provide a kind of polyurethane corner cut edge bearings, solve the above technical problem.
The technical issues of the utility model is solved can be realized using following technical scheme:
A kind of polyurethane corner cut edge bearing, including edge bearing main body, which is characterized in that the edge bearing main body include superficial layer, in
Interbed and internal layer, three is cyclic structure, and superficial layer is sheathed on outside middle layer, and middle layer is sheathed on outside internal layer, it is described in
Interbed is using middle layer made of metal；
The superficial layer is using superficial layer made of polyurethane, its both ends is respectively provided with a bulge-structure, superficial layer when expansion
On middle layer outer wall after circlewise, the concave configuration for being set to the middle layer outer wall is caught in after two bulge-structure splits
Interior, the concave configuration is arranged along the axial direction of middle layer.
For the utility model on the basis of conventional metals ring, surface is embedded in the superficial layer of polyurethane material as buffering dress
It sets, at work, the directly soft cutting of blade is on polyurethane for corner cut blade, so that the impact to becket itself is reduced, into
The vibration of one step decrease grooved shaft.The natural elasticity of polyurethane material after additionally aiding corner cut, springs back paper scrap stripping, to allow
The easier disengaging cardboard of corner cut edge grinding keeps the cleaning in carton production.
The two sides of the middle layer, which are equipped with, prevents superficial layer from generating retaining ring in axial sliding.
The retaining ring is formed after the both sides of the face fold by the cyclic structure for being located at middle layer.
The fold height of the retaining ring is not less than the thickness of the superficial layer.
The internal layer uses bearing, it is preferred to use ball bearing.The utility model is on the basis of original fixed becket
On, it is added into rolling bearing system, so that corner cut avoids head-on crash, the rotation of auxiliary bearing has been decomposed a part of corner cut and caused
Impact.
The internal layer is equipped with recess, and the recess is closed after a week along the outer wall of internal layer；It is corresponding in the centre
The convex block that the inner wall of layer is equipped with convenient for being embedded in the recess.
The utility model has the advantages that due to the adoption of the above technical scheme, the utility model is reduced when fluting portion works to becket sheet
The impact of body further weakens the vibration of grooved shaft, after additionally aiding corner cut, paper scrap stripping is sprung back, to allow corner cut edge grinding
Easier disengaging cardboard keeps the cleaning in carton production.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the explosive view of Fig. 1；
Fig. 3 is the superficial layer of the utility model and the assembling schematic diagram of middle layer；
Fig. 4 is the schematic cross-sectional view of the utility model.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face, which combines to be specifically illustrating, is further described the utility model.
Referring to figs. 1 to Fig. 4, a kind of polyurethane corner cut edge bearing, including edge bearing main body, edge bearing main body include superficial layer 1, centre
Layer 2 and internal layer 3, three is cyclic structure, and superficial layer 1 is sheathed on outside middle layer 2, and middle layer 2 is sheathed on outside internal layer 3, in
Interbed 2 is using middle layer made of metal；Internal layer 3 uses bearing, it is preferred to use ball bearing.Superficial layer 1 uses polyurethane system
At superficial layer, its both ends is respectively provided with a bulge-structure 5 when expansion, superficial layer 1 on 2 outer wall of middle layer after circlewise, two
Be caught in the concave configuration 4 for being set to middle layer outer wall after a 5 split of bulge-structure, concave configuration 4 along middle layer 2 axial direction
Setting.
The two sides of middle layer 2, which are equipped with, prevents superficial layer from generating retaining ring 6 in axial sliding.Retaining ring 6 is by the ring positioned at middle layer 2
It is formed after the both sides of the face fold of shape structure.The fold height of retaining ring 6 is not less than the thickness of superficial layer 1.Internal layer 3 is equipped with recess
7, recess 7 is closed after a week along the outer wall of internal layer 3；The corresponding inner wall in middle layer 2 is equipped with convenient for convex in insertion recess
Block 8.
For the utility model on the basis of conventional metals ring, surface is embedded in the superficial layer of polyurethane material as buffering dress
It sets, at work, the directly soft cutting of blade is on polyurethane for corner cut blade, so that the impact to becket itself is reduced, into
The vibration of one step decrease grooved shaft.The natural elasticity of polyurethane material after additionally aiding corner cut, springs back paper scrap stripping, to allow
The easier disengaging cardboard of corner cut edge grinding keeps the cleaning in carton production.
