Description
Technical field:
The present invention relates to Recombined bamboo wood integrated timber technical field, particularly Recombined bamboo wood integrated timber square stock continuous mould pressing production line.
Background technology:
Before the present invention, the method for Recombined bamboo wood integrated timber square stock, is that bamboo and wood is split and is broken into strand, and applying glue is dry, packs press die cavity into, places mould in die cavity, high-pressure molding, and then locked mode, depanning, enters high-temperature workshop hot setting sizing.Prior art is discontinuous compacting, is a batch (-type) compacting.Be generally press die cavity how long, the mould adopting is with regard to how long, the integrated timber square stock that can suppress is with regard to how long.Its defect: the one, can not suppress continuously, production efficiency is low, and production cost is high; The 2nd, can not suppress long size finished product square stock, use and cause waste, can not meet user demand.
Summary of the invention:
The object of this explanation, is the deficiency that overcomes prior art, and a kind of Recombined bamboo wood integrated timber square stock continuous mould pressing production line is provided, and adopts novel drawing method and equipment, realizes compacting bamboo wood integrated timber square stock continuously, and quality better, efficiency are high.
For reaching foregoing invention object, the technical scheme of taking is: a kind of Recombined bamboo wood integrated timber square stock continuous mould pressing production line, comprise put mould, feeding device, prepressing device, gradually pressure device, constant-voltage equipment, wear pin assembly six parts, be connected successively.
Putting mould, feeding device, prepressing device three parts is located on same conveyer belt 7.Putting mould is by connected head-to-tail the mould of prior art 1 conveyer belt 7 that is put in successively.Feeding device 2 comprises by conveyer belt 7 and its two side respectively establishes hopper 10 that row's edger roll 9 forms and to defeated feeding device in hopper, mould 1 is in hopper bottom.Prepressing device 3 is rolling pressure setting, is made up of multiple rolling wheels 13 of drive unit driving, longitudinally roll extrusion by being located in hopper 10.
Described gradually pressure device 4 is continuous pressing machine with constant-voltage equipment 5, and the two forward and backward part that is continuous pressing machine is amounted to upper crawler belt 17 and unidirectionally amounted to lower crawler belt 22 and form by upper and lower two corresponding that exert pressure, operation with closed ring unidirectional.The unidirectional mask of exerting pressure of amounting to crawler belt 17 have continuous projection pressing mold 19 ', the unidirectional pressure-bearing surface of amounting to lower crawler belt 22 have Continuous Rectangular channel mould chamber 24 ', described continuous projection pressing mold can apply pressure in described Continuous Rectangular channel mould chamber, and the pre-binder that fills in it is pressed into section bar continuously.Gradually pressure device 4 unidirectional amounted to crawler belt 17 its operation outbound parts 18 for being obliquely installed, and moves closer to from front to back the horizontally disposed unidirectional lower crawler belt 22 of amounting to, and forms can hold pre-binder and enter, lead and dehisce 14 depending on the gradually pressure that is wedge-like between the two.The unidirectional crawler belt 17 of amounting to of constant-voltage equipment 5 amounts to its operation outbound part 30 of lower crawler belt (22) close pressing parallel to each other with unidirectional; Described constant-voltage equipment 5 has constant voltage and produces maintaining body,
Described wear pin assembly 6 be located at unidirectional amount to lower crawler belt 22 with its on unidirectional amounting to after crawler belt 17 is separated, it comprises wears pin wheel 38, is located at the lifting pin mechanism 48 of wearing pin wheel one side, the described pin wheel 38 of wearing is solidified as a whole and is formed by coaxial row's pin dish 39, pilot pin dish 41, guided mode wheel 43, backing pin dish 45, and the mould 1 of transmission is on guided mode wheel 43.Described lifting pin mechanism 48 is fixed on one and moves horizontally on plate 49, and in the time wearing pin, this moves horizontally plate and mould synchronizing moving, moves horizontally plate and oppositely moves back in a stepwise manner original place when wearing keying bundle; The described pin assembly of wearing has the pin of wearing guiding mechanism.
The further preferred version of the present invention is, it is to install by qualifying bit the unidirectional fixing briquetting 31 of upper crawler belt 17 with the unidirectional Adjustable Range of amounting to lower crawler belt 22 2 sides of amounting to that is placed in phase pressing that the constant voltage of described constant-voltage equipment 5 produces maintaining body, and be arranged in order the roller 32 of rolling around fixing briquetting, the fixing briquetting 31 of two sides that limits distance by roller 32 force initiatively operation, pressing unidirectional amounted to upper crawler belt 17 and passes through from operation therebetween with the unidirectional lower crawler belt (22) of amounting to relatively, with guarantee the two each other pressing produce predetermined pressure.
The beneficial effect that the present invention produces is:
The 1st,, adopt the unidirectional crawler belt of amounting to amount to the lower crawler belt new pressure exerting arrangement of phase pressing each other with unidirectional, and coordinate constant voltage produce maintaining body, realized stock in movement by high-pressure molding.The unidirectional crawler belt of amounting to is amounted to lower crawler belt each other when phase pressing with unidirectional, and punch and Continuous Rectangular channel mould chamber present rigidity pressing plane continuously, apply pressure to therebetween by piezodielectric with surface pressure form.
The 2nd,, adopt pre-roll extrusion, gradually press, constant voltage progressively compresses, progressively increase the method for the intensity of exerting pressure, continuous is incremental, and the each section of Rational Parameters of exerting pressure, is easy to reach final pressure intensity index.
The 3rd,, adopt existing mold, place continuous crawler type backing plate New Technical Measures therein, a difficult problem that has solved continuous pressing process and can not place rigidity backing plate, has finally realized whole production line and has suppressed continuously.
Production efficiency is high, and product quality is excellent, has reduced production cost.The integrated square stock of any long size suppressing continuously, can intercept use as required, has avoided waste.
