Description
Technical field
The present invention relates to surface mounting technology (SMT) field, more particularly, relate to a kind of printing machine doctor blade device that is used on printed substrate print solder paste or red glue.
Background technology
The printing machine doctor blade device that tradition is used on printed substrate print solder paste or red glue is by the knife rest main body; The pressing plate that is fixedly connected with the knife rest main body; The wing that is clamped between knife rest main body and the pressing plate constitutes; Because after wing was installed between knife rest main body and the pressing plate, the width that wing is scraped just was a fixing width, can not regulate the width that wing is scraped; Same printing machine can only be to a kind of printed substrate print solder paste or red glue of specification; When will carry out printed substrate specification that the size of the printed substrate of print solder paste or red glue can print less than the wing of this printing machine the time, adopt the wing of this printing machine to print, must cause a large amount of tin creams or red glue to overflow on the steel mesh of printing machine; Not only cause the waste of a large amount of tin creams or red glue, also can influence the quality of the printed printed substrate that obtains.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective in the prior art: providing a kind of can regulate the width that wing is scraped; Effectively satisfy the needs that carry out print solder paste or red glue at the printed substrate of different size; Reduce tin cream or red gum consumption, energy savings, and can improve the printing machine doctor blade device of printed substrate quality.
For realizing above-mentioned purpose, technical scheme provided by the invention is following: a kind of printing machine doctor blade device is provided, comprises the knife rest main body; The pressing plate that is fixedly connected with the knife rest main body; Be clamped in the wing between knife rest main body and the pressing plate, also comprise being installed in being used for governor motion that the width that wing is scraped is regulated on the knife rest main body, said governor motion comprises first swing arm that is installed in knife rest main body one end; Be installed in second swing arm of the knife rest main body other end; Be equiped with guide rod between first swing arm, second swing arm, an end of guide rod is fixedly connected with first swing arm, and the other end of guide rod is fixedly connected with second swing arm; Leader casing is provided with first block, second block that can move along guide rod, regulates the width of printing.
First push rod that is used to withstand first swing arm is equipped with on the top of said knife rest main body one end, and second push rod that is used to withstand second swing arm is equipped with on the top of the knife rest main body other end.
The beneficial effect of printing machine doctor blade device according to the invention is: be used for governor motion that the width that wing is scraped is regulated through installing on the knife rest main body; Said governor motion comprises first swing arm that is installed in knife rest main body one end; Be installed in second swing arm of the knife rest main body other end; Be equiped with guide rod between first swing arm, second swing arm; One end of guide rod is fixedly connected with first swing arm, and the other end of guide rod is fixedly connected with second swing arm, and leader casing is provided with first block, second block that can move along guide rod.Can regulate the width that wing is scraped through this governor motion, according to carry out the specification of the printed substrate of print solder paste or red glue, first block, second block moved on the corresponding position along guide rod get final product.Can effectively satisfy the needs that on the printed substrate of different size, carry out print solder paste or red glue, reduce tin cream or red gum consumption, energy savings, glass putty oxidation in the volatilization of scaling powder and the tin cream in the minimizing tin cream; Thereby improved the environment of presswork; And improved the quality of printed substrate print solder paste, after said in addition printing machine doctor blade device is installed on the printing machine, under the pressure of printing machine; First block, second block form closely with wing, and face contacts; Can avoid tin cream or red glue between first block, second block and wing, to flow out, so the side of printed substrate do not have tin cream or red glue, improved the printed substrate quality.
Below in conjunction with accompanying drawing and embodiment printing machine doctor blade device of the present invention is described further:
Description of drawings
Fig. 1 is the front view of printing machine doctor blade device according to the invention;
Fig. 2 is one of stereogram of printing machine doctor blade device according to the invention;
Fig. 3 be printing machine doctor blade device according to the invention stereogram two.
The specific embodiment
Below be the most preferred embodiment of printing machine doctor blade device according to the invention, therefore do not limit protection scope of the present invention.
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of printing machine doctor blade device is provided, comprise knife rest main body 1; The pressing plate 2 that is fixedly connected with knife rest main body 1; Be clamped in the wing 3 between knife rest main body 1 and the pressing plate 2, also comprise being installed in being used for governor motion 4 that the width that wing 3 is scraped is regulated on the knife rest main body 1, said governor motion 4 comprises first swing arm 5 that is installed in knife rest main body 1 one ends; Be installed in second swing arm 6 of knife rest main body 1 other end; Be equiped with guide rod 7 between first swing arm 5, second swing arm 6, an end of guide rod 7 is fixedly connected with first swing arm 5, and the other end of guide rod 7 is fixedly connected with second swing arm 6; Guide rod 7 is arranged with first block 8, second block 9 that can move along guide rod 7; According to carry out the specification of the printed substrate of print solder paste or red glue, first block 8, second block 9 are moved on the corresponding position along guide rod 7 and get final product, can effectively satisfy the needs that on the printed substrate of different size, carry out print solder paste or red glue.
