Description
Technical field
The present invention relates to vertical abrasive band banding machine, specifically refer to abrasive band cutting structure.
Background technology
Banding machine is a kind of equipment that wide roll of material is carried out to longitudinal cutting, can be divided into following a few class: for itemize paper, this is also the main product in current packaging facilities, and packaging market is often visible according to its scope of application; For itemize leather, dry goods, plastics, film etc. required industry; For itemize metal coiled material, as a point band steel, stainless steel, copper etc., it is mainly used in steel processing factory pod and determines steel market operator, steel rolling producer, electrical apparatus industry, automobile, stamping parts etc.
The operating efficiency of banding machine is relevant with following factor: itemize speed, yield rate, inoperative holding time, stability etc.Itemize speed is an important indicator of banding machine operating efficiency, if but yield rate is low, and not only can cause the operating efficiency of complete machine low, and can cause the rising of cost.Equally, if inoperative holding time is long, as: tune machine, tool setting, tool changing, reload, the consumption time such as processing problem is long, the speed of simple raising banding machine, also just seems unimportant.The stability of traditional banding machine is lower, and particularly, in long use procedure, the stability decreases of complete machine not only can affect the operating efficiency of banding machine, also can have influence on product quality, more can cause trouble and unnecessary waste to next procedure.In the time that cutter is cut apart abrasive band, because the sand grains hardness on abrasive band is higher, do used time wearing and tearing mutually at cutter and abrasive band, and when the width in the abrasive band of required cutting is not of uniform size, need to change cutter, greatly extend the non-working time, also caused the practicality of banding machine complete machine greatly to reduce.
Summary of the invention
The object of the present invention is to provide abrasive band cutting structure, the convenient cutting action that tubular abrasive band is carried out to different in width size, in improving banding machine overall utility energy, reduces the wearing and tearing of cutter.
Object of the present invention is achieved through the following technical solutions:
Abrasive band cutting structure, comprise central shaft, the two ends of central shaft are rotated and are arranged on bearing block, on described central shaft, be set with dress cutter shaft, on dress cutter shaft, have the dovetail groove that multiple annular arrays distribute, described dovetail groove is coaxial with central shaft, also comprise multiple cutters and fixed block, fixed block is arranged on the end, two ends of dress cutter shaft, described cutter is slidably arranged in dovetail groove, and the bottom of cutter coordinates with dovetail groove, between adjacent two cutters, spacer is installed, dress cutter shaft is provided with tapped blind hole, spacer passes tapped blind hole by bolt and is fixed on dress cutter shaft, the two ends of spacer and the end contact of cutter.When the present invention works, under the drive of central shaft external drive equipment, start rotation, the dress cutter shaft band cutter being sleeved on central shaft starts circumgyration incision, cutter is slidably arranged in dovetail groove, and cutter is fixed on dress cutter shaft by spacer, the size of spacer is selected to carry out according to the width in required abrasive band, in the time that the ambilateral spacer size of cutter is identical, be that the emery stick width that cuts out of cutter is identical, in the time that the ambilateral spacer size of cutter is not identical, spacing between two adjacent cutters is not identical, make in abrasive band when cut the emery stick of the multiple width of output simultaneously, avoid the frequent cutter of changing in process, shorten the non-working time, improve widely practicality of the present invention, dovetail groove is coaxial with central shaft, and the length of the Length Ratio central shaft of dovetail groove is slightly short, can ensure cutter the moving freely of long distance on dress cutter shaft, ensure that the spacing between two adjacent cutters is adjustable flexibly, the emery stick width range cutting out is larger, and practicality is higher, multiple dovetail groove annular arrays are distributed on dress cutter shaft, and multiple cutters are kept at a certain distance away in same planar annular, in the time of cutter High Rotation Speed, reduce the wearing and tearing between cutter and abrasive band, improve service life of the present invention.
Described cutter comprises interconnective circular arc cutter head and support portion, and described support portion is trapezoidal, and support portion coordinates with dovetail groove.Circular arc cutter head can ensure to have longer time of contact between abrasive band in the time of cutting, trapezoidal support portion coordinates with dovetail groove, make cutter and there is stronger stability in High Rotation Speed process and when with abrasive band contact, avoid cutter at work to become flexible and cause the quality of cutting abrasive band to reduce.
The spacer B that described spacer comprises spaced spacer A and matches with spacer A, when work described in spacer A and spacer B be separately fixed at the both sides of cutter.In the time that the emery stick width after required cutting is identical, spacer A is identical with spacer B's, ensures that the spacing between each blade equates; In the time that the width of spacer A is less than spacer B, spacing between two adjacent cutters is unequal, and the emery stick width obtaining after abrasive band is cut is also not quite similar, and ensures that the present invention is not in the situation that changing cutter, produce the emery stick of different in width simultaneously, greatly increased its scope of application.
Also comprise end cap, the two ends up and down of described end cap are connected with fixed block by clamping screw, and end cap is run through at the two ends of described central shaft.While cutting in abrasive band, can produce more chip and dust, by end cap, central shaft and dress cutter shaft are sealed, avoid the chip and the dust that splash to enter into bearing block or dovetail groove everywhere, reduce, on the impact that central shaft rotates and cutter moves, to ensure job stability of the present invention.
The number of described dovetail groove is 3 or 4.As preferably, the number that annular array is distributed in the dovetail groove on dress cutter shaft is 3 or 4, in ensureing that cutter has enough cutting dynamics to abrasive band, avoid too much cutter need to carry out numerous and diverse step in the time adjusting spacer, improve operating efficiency of the present invention.
The present invention compared with prior art, has following advantage and beneficial effect:
1, abrasive band of the present invention cutting structure, in the time that the ambilateral spacer size of cutter is identical, be that the emery stick width that cuts out of cutter is identical, in the time that the ambilateral spacer size of cutter is not identical, spacing between two adjacent cutters is not identical, makes in abrasive band when cut the emery stick of the multiple width of output simultaneously, avoids the frequent cutter of changing in process, shorten the non-working time, improved widely practicality of the present invention;
2, abrasive band of the present invention cutting structure, by central shaft and the sealing of dress cutter shaft, avoids the chip and the dust that splash to enter into bearing block or dovetail groove by end cap everywhere, reduces, on the impact that central shaft rotates and cutter moves, to ensure job stability of the present invention;
3, abrasive band of the present invention cutting structure, the number of the dovetail groove of shape array distribution on dress cutter shaft is 3 or 4, in ensureing that cutter has enough cutting dynamics to abrasive band, avoid too much cutter need to carry out numerous and diverse step in the time adjusting spacer, improve operating efficiency of the present invention.
