Description
Technical field
The present invention relates to a kind of doffer's device that is installed on the non-woven carding machine, especially relate to a kind of suction type doffer's device that is installed on the non-woven carding machine.This device with crimpness on the main cylinder the short fiber of little and length effectively transfer to the cohesion roller, machinable fibrous raw material scope is wide, the speed of production height is a kind of become net good uniformity, doffer's device that raw material availability is high.
Background technology
Non-woven carding machine is that nonwoven material becomes the key equipment in the net operation.This equipment is made up of the various card clothing on working roll, angle stripper, main cylinder, doffer, cohesion roller and each roller surface of looping.Wherein, the doffer is positioned in the middle of main cylinder and the cohesion roller, its effect be with on the main cylinder through the fibre migration of repeatedly combing to the cohesion roller.This shows that the doffer is a critical component in the whole carding machine.Traditional doffer's device is made up of roller, central shaft, left end cap, right end cap and the looping doff clothing on the roller outer surface.Wherein, roller is columniform hollow cylinder, and its external diameter is 500～700mm, and length is 1300～3800mm, and wall thickness is 16～26mm, and material is a carbon steel; Central shaft is the solid rod that places the roller center, and its diameter is 100～120mm, and length is 2200～4700mm, and material is a carbon steel; Left and right end cap is made up of spoke and shrouding, and wherein the spoke of spoke respectively has 5～6, and shrouding is fixed on and is used to seal roller on the spoke, prevents that fiber and dust from entering roller inside; Doff clothing on the looping roller outer surface is made up of the base portion of the metal solid that is the bandlet shape and the pin tooth that is evenly distributed on above the base portion, card clothing is with direct rolling the forming of steel wire, base portion is used to support whole pin tooth, the relevant parameter of conventional doff clothing is 0.9～1.2mm for base portion thickness, tooth pitch is 2～3mm, the angle of pin tooth and base portion bottom surface is that the card wire operating angle is 40 °～60 °, the summation of card clothing base portion height and pin tooth height is that total tooth depth is 3～5mm, and the base of card clothing base portion and roller intimate are fitted.The card clothing looping is on the roller outer surface, and roller and spoke are consolidated, and spoke and central shaft are consolidated, and drives whole doffer's device by the drive disk assembly that is fixed on central shaft one end again and rotates and finish fibre migration.Because all not being provided with gas channel on roller, central shaft and the doff clothing of above-mentioned traditional doffer's device is pore, thereby be no absorption affinity to the fiber that shifted on its doffer surface, especially the short fiber of the little and length of crimpness free and coming off on the easier doffer of the causing surface when carding machine is running up, thereby cause fibre web through traditional doffer's device gained to exist the defective that fibre web surface density lack of homogeneity and raw material overall utilization descend.
Patent of invention US4969235 discloses a kind of cover plate type carding machine or roller and clearer card device that is used for removing the staple fibre of like fibrous such as cotton, synthetic fiber.This device on the cover board is furnished with a series of aspirators with the cylinder periphery, this goal of the invention is raw material middle short fiber and impurity to be removed from the Bearded-needle knitted cloth surface that to reach the fibre web surface density even by external suction means, therefore the method for this outer suction is when removing staple fibre, but reduce the raw material overall utilization, increased the production totle drilling cost.
Patent of invention CN1224740C discloses the special-purpose doffer's metallic card clothing of a kind of soybean fiber.This invention has only changed the pin toothing on the basis of the architectural feature that keeps conventional conventional needle cloth base portion, promptly adopt two anterior angles and the design of acupuncture end shape to be convex syringe needle shape.Though this structure helps extracting, the branch comb to soybean fiber and shifts, and can finish the transfer of this specialty fibers raw material smoothly, but the selected raw material of this invention only limits to soybean fiber, the speed of production of selected carding machine only limits to the medium speed, and the free uncontrollable defective of fiber that is produced when still existing short other fiber combings of to crimpness little and length or during high-speed production.
In a word, because above-mentioned prior art can't be adsorbed the fiber that crimpness is low and length is short that shifts on the control doffer roller lower surface when carding, the fibre web surface density is irregular, the raw material scope of application is narrow, the raw material overall utilization low and the defective of production speed limit thereby cause.
Summary of the invention
In order to overcome the above-mentioned defective that exists in the prior art, main purpose of the present invention provides a kind of improved suction type doffer's device that is installed on the non-woven carding machine.The short fiber of little and length has suction-operated to crimpness during the work of this device, thereby prevents this fibrid free in the high-speed production process and come off; This device can adapt to different fibrous raw materials and main cylinder, condense the requirement of the different installation sites of roller, and machinable fibrous raw material scope is wide, the speed of production height.Compare with traditional doffer's device, through the fibre web surface density good uniformity of this device combing processing gained, raw material overall utilization height.
The technical problem that the present invention need solve is: but mainly solve the problem that traditional doffer's device is widened processing fiber raw material range, raising speed of production, raising fibre web surface density uniformity, improved the raw material overall utilization of how improving; Solve how the gas channel that connects with sucktion fan on roller body, mandrel and the card clothing is set, and suction system in forming, thereby the low length that reaches of doffer's apparatus surface crimpness is produced adsorbing problem than staple fibre; Solve and how to select deep bead and the hairbrush parts of being set up in the roller chamber body and how to be fixed in problem on the mandrel; How to regulate deep bead and hairbrush position component control negative pressure-pumping district size in the roller chamber body thereby solve, to adapt to the problem of different fibrous raw materials and main cylinder, the different installation sites requirement of cohesion roller; Solve the roller body around relevant technologies problems such as fixed mandrel rotations.
