Description

  The present invention relates to a paste strainer that removes impurities in a paste used in screen printing or the like to eliminate screen printing troubles.

A conventional paste strainer has a structure in which a blade for extruding paste from a filter is rotatably mounted in a paste strainer having a filter disposed on the bottom.

For this reason, the paste stored in the paste strainer is rotated on the filter by the blade, and the high-viscosity paste cannot be efficiently rubbed.
Patent 3014411

    SUMMARY OF THE INVENTION In view of the above-described conventional drawbacks, the present invention provides a paste strainer that can efficiently rub a paste by preventing it from rotating without being rubbed by a filter even if it is a high-viscosity paste. The purpose is to do.

The above and other objects and novel features of the present invention will become more fully apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are for explanation only and do not limit the technical scope of the present invention.

In order to achieve the above object, the present invention provides a support base in which a through hole is formed in an upper support plate, and a ring-shaped rotary body that is rotatably attached to the outer periphery of the through hole of the support plate of the support base. And a rotation drive device for rotationally driving the ring-shaped rotating body, and a cylindrical paste strainer having a filter attached to a bottom portion which is directly attached to the ring-shaped rotating body or non-rotatably attached to the ring-shaped base plate. Magnets at the ends of the container and in the shape of a bar, Y-shape, or cross that is housed in the paste strainer and has an inclined surface that can press the paste housed in the upper part of the filter toward the filter. Alternatively, the blade attached with the metal adsorbed by the magnet and the metal adsorbed by the magnet of the blade or the magnet adsorbed on the magnet at the outer periphery of the paste strainer There constitute with a magnet, a paste strained machine with a blade fixture which is mounted on a support plate of the support base.

  As is clear from the above description, the present invention has the following effects.

(1) A support base in which a through hole is formed in a support plate on the upper surface, a ring-shaped rotating body that is rotatably attached to the outer peripheral portion of the through-hole of the support plate of the support base, and the ring-shaped rotating body A rotary drive device for rotationally driving, a cylindrical paste strainer having a filter attached to the bottom thereof, which is directly attached to the ring-shaped rotating body or non-rotatably attached to the ring-shaped base plate, and the inside of the paste strainer The metal or the metal adsorbed by the magnet is attached to the end of the rod-shaped, Y-shaped or cross-shaped, which is housed in the shape of an inclined surface that can press the paste stored in the upper part of the filter in the filter direction. The support comprising: an attached blade; and a metal or a magnet adsorbed by a magnet of the blade or a magnet adsorbed by the magnet at the outer periphery of the paste strainer Since the support plate mounted blade fixture is composed of, it is possible to paste strained vessel paste is housed blade in a fixed state is rotated.
Accordingly, the paste on the filter is efficiently pressed against the filter by the fixed blade, and can be rubbed without turning around as before.

(2) According to the above (1), since the blade is not attached to the rotating shaft as in the prior art, it can be easily taken out from the paste strainer and easily cleaned.

(3) According to the above (1), since it is only necessary to put a blade into the paste strainer, it is not necessary to adjust the position of the blade, it can be used easily, and a plurality of paste strainers in which the blades are stored are provided. Can be used repeatedly.

(4) In claim 2, the same effects as in the above (1) to (3) can be obtained.

(5) In claim 3, the same effects as in the above (1) to (3) can be obtained, and an inexpensive filter including only a mesh can be used.

A rotary drive device 12 comprising a motor 11 attached and mounted in the support 5 and a plurality of stages non-rotatably attached to a ring-shaped base plate 13 fixed to the ring-shaped gear 8. In the embodiment to implement in two stages Cylindrical paste paste containers 14, 14, 14 that are overlapped, and a cross shape housed in paste paste containers 14, 14, 14, and magnets 15, 15, 15, 15 are attached to the ends. Magnets 17, 17, 17, 17 that are attracted to the blades 16, 16, 16 and the magnets 15, 15, 15, 15 of the blades 16, 16, 16 at the outer periphery of the paste strainers 14, 14, 14. The blade fixtures 18, 18, 18, 18 attached to the support plate 2 of the support base 5 are provided.

As shown in FIGS. 5 and 6, the paste strainer containers 14, 14, 14 are cylindrical paste strainer main bodies 19 formed of a non-magnetic stainless steel material and the upper and lower surfaces of the paste strainer main body 19. The upper and lower flange portions 20 and 21 having a larger diameter from the upper portion and the ring-shaped groove 23 as the engagement portion 22 formed on the bottom surface of the lower flange portion 21 are formed so as to protrude outward. A ring-shaped projecting piece 25 as an engaging portion 24 that engages with the ring-shaped groove 23 is formed on the upper surface, and is fixed to the lower flange portion 21 with a plurality of bolts 26, 26, 26, 26. A ring-shaped filter fixture 27, and an outer circumferential portion between the filter-fixing portion 27 and the lower flange portion 21 is applied with a tension in the outer circumferential direction by the ring-shaped groove 23 and the ring-shaped projecting piece 25. Firmly A filter 28 which is, and a said recess 27a of the upper flange portion 20 formed on the bottom surface of the filter fixing member 27 enters.
The filters 28, 28, 28 of the paste strainers 14, 14, 14 are used as coarse, medium and fine from the top.

  The blades 16, 16, 16 are formed so as to be able to press the cross-shaped blade body 29 and the paste 30 formed on the upstream side of the blade body 29 toward the filter 28 as shown in FIGS. 7 and 8. Inclined surfaces 31, 31, 31, 31, magnets 15, 15, 15, 15 housed and fixed in recesses 32, 32, 32, 32 formed at the end of the blade body 29, and the blade body 29 The grip ribs 33 are integrally formed so as to protrude upward on the upper surface of the substantially central portion.

  Ends of the blades 16, 16, 16 are provided on the support plate 2 of the support base 5 so that the blade fixtures 18, 18, 18, 18 are located on the outer periphery of the paste strainer containers 14, 14, 14. The pillars 34, 34, 34, 34 fixed to the part corresponding to the position to be positioned, and attached to the pillars 34, 34, 34, 34 so as to protrude toward the end portions of the blades 16, 16, 16 respectively. The arms 35, 35, 35, 35 are provided with magnets 17, 17, 17, 17 at their tips, and the arms 35, 35, 35, 35 are fixed to the paste strainers 14, 14, 14. It can be taken in and out.

The paste strainer 1 configured as described above stores and stacks the blades 16, 16, 16 in the paste strainers 14, 14, 14, and stores the paste 30 for removing impurities in the uppermost paste strainer 14, When the motor 11 of the rotation driving device 12 is driven, the ring gear 8 is rotated by the pinion 9, and the paste paste containers 14, 14, and 14 stacked are rotated.
When the paste strainers 14, 14, 14 are rotated, the magnets 15, 15, 15, 15 at the ends of the blades 16, 16, 16 are magnets of the blade fixtures 18, 18, 18, 18 as shown in FIG. 17, 17, 17, 17 are in an adsorbing state and are in a fixed state.
Therefore, the paste 30 on the filters 28, 28, 28 of the paste strainers 14, 14, 14 is pushed toward the filters 28, 28, 28 by the inclined surfaces 31, 31, 31, 31 of the blades 16, 16, 16. It becomes a pressed state, and the paste can be efficiently rubbed.
