Description

A kind of method of manufacturing paper tube with pulp and machinery

Technical field

The present invention relates to manufacture method and the machinery of paper tube.

Background technology

Directly manufacturing paper tube with paper pulp is substitute the development trend manufacturing paper tube traditional handicraft with cardboard.This field current has many schemes and puts into practice, basic fundamental situation is reflected: (one) copy paper forms the technology of paper tube base by the patent information that patent retrieval net is respectively 02143870.6 and 200610085243.5 and 94108470.1 for keyword retrieval to application number with " % paper pulp % paper tube % " at name field, substantially all belong to " injection molding ", that is: paper pulp is made to enter in the closed cavity be made up of inside and outside casting mould, compression dehydration obtains l Water Paper pipe, wherein paper pulp enters mould has pump to suck, be pumped into, machinery press-in etc., the direction of compression has along mould radial, axially, from inside to outside, from outside to inside, compress mode has machinery, pneumatic, hydraulic pressure etc., (2) heat-shaping technology, with pressurization, heating means make l Water Paper pipe solidify in drying, concrete grammar roughly have with mold heating and the demoulding move to special heater (mold) heat, heat resource form is steam mainly, hot blast.But do not promote in the textile industry had the call with the paper tube that these technology are produced, trace it to its cause mainly: three step actions that (1) " injection molding " must have " slurry enters, expressed water, deviate from work ", the inevitable relative complex of its machinery, (2) serious with mold heating heat waste, (3) sizing must be held in the palm and thus be affected the efficiency of heating surface in mould, (4) heat power supply device bulky complex.Even present situation illustrates that this art efficiency is low, cost is high, can not meet the need of market.

Summary of the invention

Not enough for art technology, focus on and raise the efficiency, invent following content:

1) utilize negative pressure midge to form device-vacuum grid core rod of paper tube base, (see (accompanying drawing 1) bold portion) vacuum grid core rod is made up of dictyosome WMX and pinion stand CLZ.Dictyosome WMX appearance profile, with the Internal periphery of paper tube, is made with low thermal conductivity, stainless organic material, and hollow, surface groove W2, the bottom land aperture W3 that gathers that gathers leads to mesopore, covers one deck stainless (steel) wire W1, has good gas permeability.Pinion stand CLZ is made of metal, be connected with dictyosome with screw, there are upper and lower two circle gear Cs 1, C2 in its surface in order to accept and to transmit power, and hollow, inwall are inlayed copper sheathing TT and to make to be enclosed within together with vacuum grid core rod with sealing ring MQ hollow shaft B rotated flexible and has good air-tightness.This device volume is little, structure is simple, and not only alternative mold generated paper tube base, but also can serve as the part of mold in heat-shaping operation.

2) method (see (accompanying drawing 1) dotted portion) of paper tube is produced by vacuum grid core rod copy paper, there is drive unit horizontally disposed hollow spindle A one end, the other end be tightly connected device be communicated with vacuum source (negative pressure-0.05 is to-0.06MP), the some hollow fulcrum B of vertical connection on main shaft, vacuum grid core rod is enclosed within fulcrum B, vacuum grid core rod can around the rotation of B axle, also can revolve round the sun with principal axis A, paper pulp pond J1 is provided with below main shaft, J2, main shaft is taken vacuum nethike embrane core and is gone to G2, submerge during G3 position stock tank, now open vacuum, paper pulp is adsorbed on vacuum grid core rod and forms l Water Paper pipe.Regulate vacuum nethike embrane core can control paper tube wall thickness in pond holdup time and vacuum.Main shaft continues to go to position G4 and carries out heat-shaping, goes to position G1 afterwards again and takes off paper tube, completes a tubulation cycle.This method adopts vacuum nethike embrane core only just can realize " injection molding " three step action function that just can complete with main axis certain angle, and thus efficiency increases and equipment is simplified.

3) method (see (accompanying drawing 1) dotted portion) of a kind of use different slurry two-layer compound tubulation, principal axis A is taken vacuum grid core rod and is first forwarded position G2 to from original position G1, in stock tank J1, adsorb the basal layer that paper pulp more inferior forms paper tube, forward position G3 again to, in stock tank J2, adsorb the paper pulp of one deck compared with high-quality as surface layer, two-layerly after principal axis A forwards position G4 to be closely complex as a whole (period negative pressure continue keep) through roll-in, heating.Use poor quality or secondary stock to manufacture the problem that paper tube cannot guarantee quality and safe and sanitary if this method solves other method, effectively reduce paper tube manufacturing cost.

4) a kind of device-internal combustion type gas heating setting roll JRG for shaping to l Water Paper heating of pipe blank (see (accompanying drawing 2), is made up of roller body GT, joint JT, axle bed ZZ, gas nozzle PZ, adjustment cap TJ.Roll body is steel-casting, and outer contour and paper tube coincide, on an empty stomach as combustion chamber, wall thickness about 6 millimeters, outer wall has decorative pattern with to paper tube embossing, surface spraying polytetrafluoroethylene (PTFE) with under high temperature-proof with paper pulp adhesion.Joint JT hollow, be the premixer HS of combustion gas and air, be connected with roll body with screw, connecting end surface has the secondary passage QK of outside logical combustion chamber, has premixer toward the flame outlet HK of combustion chamber, its outer ring has gear C 2J operationally to engage with C2, after roll body is combined with joint, its two ends have ball bearing ZC to be connected with lower carriage with by axle bed ZZ with upper bracket ZJ respectively, make it rotate flexibly.The axle bed ZZ interpolation gas nozzle PZ of hollow, the combustion gas of ejection enters premixer after throat HB mixes with the air entered by the enterprising pore JQ of adjustment cap TJ, and flame sprays to its inwall from bottom of combustion chamber, and hot gas pastes inwall rising and discharges from upper outlet CK.Regulating gas discharge rate makes this roller have two states: duty, temperature 150-260 DEG C; Wait state, only to keep in a fire.This unit temp is high, heat large, and volume is little, instead of huge heat power supply device (as boiler etc.); Instead of the molding device of traditional heating together with vacuum grid core rod, owing to adopting combustion technology directly, without the conversion links of heat energy and intermediate transfer process, so the thermal efficiency is this area, existing all kinds of heater is incomparable.

5) a kind of method for heat-shaping l Water Paper pipe-ring roll-type heat-shaping method, this method adopts internal combustion type gas heating setting roll group RGZ (see accompanying drawing 3)) surrounding can the annular of folding, open at ordinary times and be placed in G4 both sides, main shaft operating position, when vacuum grid core rod take l Water Paper pipe proceed to position G4 time, annular closed (see (accompanying drawing 4)), period external impetus made heat-shaping roller and the l Water Paper pipe synchronous axial system (see (accompanying drawing 5)) of surrounding through intermeshing gear QD, C1/C2, C2J by chain ZL, LT; In rotation, pressure, transferring heat are applied to l Water Paper pipe radial direction; Vacuum nethike embrane core keeps negative pressure simultaneously, is taken away by the steam of generation.The external mold effect that in this process, vacuum grid core rod plays the internal mold effect of mold, heat-shaping roller plays mold.Quality and the production efficiency of paper tube is controlled by the pressure of adjusting rotary speed, heat-shaping roller, temperature, vacuum grid core rod vacuum, time.First remove negative pressure before this process terminates to make to loosen so that the demoulding between paper tube and vacuum grid core rod.This method does not have the transfer process of l Water Paper pipe, solves the problem that the de-mold of prior art paper tube base heats idle thermal losses height and the difficult demoulding, owing to have employed internal combustion type heat-shaping roller and heating in vacuum technology, so efficiency doubles than other method.

6) a kind of paper tube utilizes the method (see (accompanying drawing 6)) of heat energy in producing, after l Water Paper pipe is formed without roll extrusion and negative pressure make it gradually reduce to become closely knit before for some time (about 10 seconds) in loose good ventilative state, now directly toast l Water Paper pipe with plasma state gas flame injection apparatus PHK, under suction function, heat runs through paper tube wall and reaches deep layer, rapid on the whole it is heated to 100 DEG C from normal temperature, control flame temperature and time the unlikely surface of chien shih burn.This method can also effectively prevent from using high-temperature heating roller easily to produce the problem of roll surface " sticky ".
