Detailed description of the invention
One of core of the present utility model is to provide a kind of die head of convenient burnt material cleaning, Jiao in mould head of blow-moulding machine between inner membrance lip and adventitia lip can be made to expect easy cleaning, thus improves cleaning efficiency, and effectively avoids instrument to the scuffing of inner membrance lip and adventitia lip.
Another core of the present utility model is to provide a kind of blow moulding machine with above-mentioned die head.
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1, the structural representation of die head of Fig. 1 for providing in the utility model embodiment.
The die head of the convenient burnt material cleaning provided in the utility model embodiment, comprise film lip, and film lip specifically comprises inner membrance lip 1 and is set in the adventitia lip 2 of inner membrance lip 1 outside, also comprise in this die head and being connected with inner membrance lip 1 or adventitia lip 2, and the drive unit producing axial relative motion between inner membrance lip 1 and adventitia lip 2 can be made.
Because drive unit can make inner membrance lip 1 and adventitia lip 2 produce axial relative motion, and the outer surface of inner membrance lip 1 and the inner surface of adventitia lip 2 after producing axial relative movement, just can be made to expose, for the gap between original inner membrance lip 1 and adventitia lip 2, the outer surface of the inner membrance lip 1 after exposure and the inner surface of adventitia lip 2 become easy cleaning, and cleaning tool is not easy and inner membrance lip and adventitia lip generation swiping when clearing up, this not only effectively can improve the cleaning efficiency of Jiao's material in mould head of blow-moulding machine between inner membrance lip 1 and adventitia lip 2, also can effectively avoid cleaning tool to the scuffing of inner membrance lip 1 and adventitia lip 2 simultaneously, this also will effectively be avoided the generation of film lip line on finished plastic film.
What needs were described is, Jiao's material mentioned in above-described embodiment specifically refers to the material sticked in the process of blowing between inner membrance lip 1 and adventitia lip 2, these materials due to the time retained in die head position longer, thus usually present the color of burning, therefore be called burnt material.
It is easily understood that, the drive unit that inner membrance lip 1 and adventitia lip 2 can be made to produce axial relative motion has multiple, in the die head of the convenient burnt material cleaning such as, provided in the present embodiment, drive unit is piston cylinder, and the cylinder body of piston cylinder and adventitia lip 2 are connected, pistons end and the inner membrance lip 1 of piston cylinder are connected, when needs carry out the cleaning of Jiao's material, the motion of piston is moved driving the inner membrance lip 1 be connected with it, thus inner membrance lip 1 and adventitia lip 2 are staggered, the outer surface of inner membrance lip 1 and the inner surface of adventitia lip 2 expose, thus the cleaning of convenient burnt material.
Certainly, the cylinder body of piston cylinder can also be connected with inner membrance lip 1, and the end of piston is connected with adventitia lip 2, and this can realize the axial relative motion between inner membrance lip 1 and adventitia lip 2 equally, and piston cylinder can be the one in hydraulic cylinder or cylinder.
The utility model embodiments provides the die head that another can realize inner membrance lip 1 and the axial relative motion of adventitia lip 2, drive unit in this die head specifically comprises screw rod 6, sleeve 5 and hydraulic pump 3, please refer to Fig. 1, the end of screw rod 6 is embedded at the bottom of inner membrance lip 1, and screw rod 6 and inner membrance lip 1 are for being rotatably connected, screw rod 6 one aspect can form axial support to inner membrance lip 1, on the other hand can produce rotation along screw rod 6 own axes direction relative to inner membrance lip 1, sleeve 5 is set in the outside of screw rod 6, and sleeve 5 and screw rod 6 screw togather, sleeve 5 is connected on adventitia lip 2 simultaneously, hydraulic pump 3 is connected with the bottom of sleeve 5 by liquid line 4, and can be filled with in sleeve 5 or reclaim highly pressurised liquid.
When needs carry out the cleaning of Jiao's material, hydraulic pump 3 will input highly pressurised liquid in sleeve 5, now the promotion backspin at highly pressurised liquid turns and moves upward by screw rod 6, thus drive the inner membrance lip 1 be rotatably connected with it to move upward, inner membrance lip 1 and adventitia lip 2 will stagger, the outer surface of inner membrance lip 1 and the inner surface of adventitia lip 2 are exposed, the cleaning of convenient burnt material.
Screw rod 6 for support envelope lip 1 can be one also can be many, when being only provided with a screw rod 6 and carrying out support envelope lip, screw rod 6 should be arranged on the center position of inner membrance lip 1, avoid the inclination of inner membrance lip 1, when being provided with many screw rods 6, an axis in many screw rods 6 can overlap with the center line of inner membrance lip 1, and remaining screw rod 6 should be uniformly distributed along the circumference of this screw rod 6, to make the support degree of each screw rod 6 reach unanimity; Or when being provided with many screw rods 6, many screw rods 6 are all uniformly distributed along the circumference of the center line of inner membrance lip 1 also can.
Also disclose a kind of blow moulding machine in the utility model, this blow moulding machine comprises die head, and this die head is the die head of convenient burnt material cleaning disclosed in above-mentioned any embodiment.
Owing to comprising the die head of the convenient burnt material cleaning in above-described embodiment in this blow moulding machine, thus this blow moulding machine has all advantages of above-mentioned die head concurrently, no longer repeats in present specification to this.
Above the die head of blow moulding machine provided by the utility model and convenient material cleaning is described in detail.Apply specific case herein to set forth principle of the present utility model and embodiment, the explanation of above embodiment just understands method of the present utility model and core concept thereof for helping.Should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle, can also carry out some improvement and modification to the utility model, these improve and modify and also fall in the protection domain of the utility model claim.
