Description

A kind of hob type device for preparing leather sample
Technical field
The invention belongs to leather physics parameter testing technical field, relate to a kind of producing for leather physics parameter testing The device of leather sample, especially a kind of hob type device for preparing leather sample.
Background technology
Shrinkage temperature is the important physical parameter detecting project of leather, particularly refers to that leather sample heats up at continuous uniform During start to shrink at the ambient temperature corresponding to the moment, be itself intrinsic characteristic.By accurately detecting its shrinkage temperature, By kneading situation and the wet stability of heat of this leather of direct reaction, carry for the determination of rapidoprint and environmental condition in kneading technique For data support, also for being processed further making leatherware or purposes selection offer guidance.
Although along with the development of science and technology, the method and apparatus of detection shrinkage temperature also has a variety of, as the most original GJ901 type pointer-type leather shrinking temperature determinator, and currently use most commonly used MSW-YD4 type digital leather receipts Contracting temperature-indicating instrument etc., but its operation principle is all with QB/T2706-2005 standard: " leather, chemistry, physics, machinery and color Fastness test sampling point " based on, the most no matter use the shrinkage temperature of which kind of method and device detection leather, it is necessary to 50*3mm is produced according to standard-required2Leather sample.
And existing produce 50*3mm2The device of leather sample is the edge of a knife and the leather sample of line contact type, i.e. cutting tool In parastate, therefore it is to cut leather sample with rectangular perimeter formula linear contact lay.And this linear contact lay mode makes demand apply Pressure reach hundreds of upper metric ton.Therefore produce the device of leather sample all by means of motor or starter as dynamic Power completes to sample operation, and the weight of this device own commonly reaches about 300 kilograms, bulky, and operation inconvenience.To the greatest extent Pipe uses the mode of manual operation hydraulic jack to complete disposably to cut prepared leather sample after improving, it is still desirable to The pressure of upper metric ton, and the weight of this sampler own still reaches more than 5 kilograms.
Summary of the invention
It is an object of the invention to provide a kind of hob type device for preparing leather sample, it is ensured that the edge of a knife and skin sample surface are in system Spatially change into from linear contact lay during bark fetching sample and be in the cut state with point cantact all the time, and in time cutting The moment cutting operation is extended for the method for a period of time, thus due to cutter when effectively solving prior art is produced leather sample In tool, knife-edge plane and leather surface are in parastate all the time, and with the cutting mode moment institute of rectangular perimeter formula linear contact lay Excess pressure is needed to cause the problem that device for making volume is big, weight is big so that device for preparing leather sample is simple, manual behaviour Facilitate, and edge of a knife protection is easier to realize.
It is an object of the invention to be achieved through the following technical solutions:
This hob type device for preparing leather sample, be arranged in parallel including cutter shaft and driven shaft, cutter shaft and driven shaft, Cutter shaft can drive driven shaft to rotate simultaneously；Hobboing cutter wheel construction it is provided with on cutter shaft；Hobboing cutter wheel construction includes being enclosed within hobboing cutter Two annular blades on axle；Hobboing cutter wheel construction also includes the crosscutting blade being horizontally installed between two blades.
Further, the feature of the present invention also resides in:
The wherein integral multiple of the Zhou Changwei 50mm of blade.
Being provided with multiple crosscutting blade between two of which blade, the arc length between adjacent two crosscutting blades is 50mm.
Wherein cutter shaft is coupled together by driving gear with the same side of driven shaft；Cutter shaft and the opposite side of driven shaft Connected by bearing element.
Wherein one end of cutter shaft is provided with connection end, connects and is provided with connector on end.
Connector wherein inserts hand crank or motor output shaft, drives the rotation of cutter shaft.
Wherein being provided with two or more hobboing cutter wheel construction on cutter shaft, hobboing cutter wheel construction is arranged on rolling uniformly On cutter shaft.
Wherein it is additionally provided with some fixing teeth on cutter shaft.
Wherein be additionally provided with bolt handle on driven shaft, bolt handle for adjust between driven shaft and cutter shaft away from From.
The invention has the beneficial effects as follows: according to QB/T2706-2005 standard, the distance between two blades is 3mm, therefore Being put between cutter shaft and driven shaft by leather, cutter shaft rotarily drives the leather sample that can be used for test under blade cutting. This apparatus structure is simple, it is easy to operation, uses the mode of point cantact that leather is carried out cutting, and the pressure of needs is less；Same phase For existing device, assembly of the invention volume and weight reduces.
Further, the Zhou Changwei n*50mm, n of cutter shaft is integer；Cutter shaft rotates a circle and can cut out n* The leather bar of 50mm length；Meanwhile, it is provided with multiple crosscutting blade between blade, and crosscutting blade is at hobboing cutter wheel construction rotary course In be combined with driven shaft and to carry out crosscutting, therefore while hobboing cutter wheel construction rotates a circle, multiple crosscutting blades can cut out n Individual 50*3mm2Leather sample.
Further, cutter shaft and the two ends with driven shaft are connected by driving gear and bearing respectively, it is achieved hobboing cutter Rotate while axle and driven shaft；Can be connected with hand crank or motor output shaft by connection end on cutter shaft, it is achieved rolling Cutter shaft can manual drive rotate, or motor drives the selection modes such as rotation.
Further, because 4mm width leather standard specimen is too narrow, so be symmetricly set on cutter shaft two hobboing cutter wheels Structure, it is possible to the rolling pressure of balance hobboing cutter wheel construction, makes hobboing cutter wheel the most equalize with the intermolecular forces of driven pulley when cutting.
Further, fixing tooth is used for assisting leather stable mobile between cutter shaft and driven shaft, and in order to be suitable for The thickness of leather, the height arranging fixing tooth is 3.5mm, and the height of blade is 4.5mm.
Further, driven shaft is additionally provided with bolt handle, in order to use the reasons such as abrasion at any time according to the edge of a knife The distance between driven shaft and cutter shaft is adjusted by bolt handle.
