UTILITY MODEL CONTENT

[0004] The utility model aims at providing a kind of terpineol extrusion filter device for conductive silver paste preparation to solve the problems raised in the above background.

[0005] To solve the above technical problems, the technical scheme adopted by the utility model is:

[0008] The extrusion unit includes extrusion plate movably installed in the inside of the extrusion box.

[0009] The filter unit includes sieve screen plate movably installed in the inside of the filter box.

[0010] The further improvement of the technical scheme of the utility model is that: the both sides of the extrusion box are fixedly installed with limit block on outer surface, the left outer surface of the filter box is fixedly installed with motor, the output end of the motor is fixedly connected with turntable, and the limit block can limit the up-down reciprocating motion of abutting rod and pushing bracket.

[0011] A further improvement of the present invention is that: a brake block is fixedly connected to one side of the outer surface of the turntable, a brake sleeve is movably sleeved on the outer surface of the brake block, and a push bracket is fixedly connected to the top middle position of the brake sleeve.

[0012] A further improvement of this utility model is that: connecting rods are fixedly installed on both the top and bottom sides of the push bracket, and the other end of the connecting rods is fixedly installed on the top of the extrusion plate. A filter screen is fixedly installed on the bottom of the inner wall of the extrusion box below the extrusion plate, and the filter screen can perform preliminary filtration of terpineol.

[0013] A further improvement of this utility model is that a guide plate is fixedly installed on the inner left side of the filter box, and a leak-proof groove is fixedly installed on the bottom left side of the filter box.

[0014] A further improvement of this utility model is that an abutment rod is fixedly installed at the middle position of the bottom end of the brake sleeve, and the other end of the abutment rod passes through the left through hole of the filter box and extends above the screening screen plate.

[0015] A further improvement of this utility model is that: a sliding rod is movably inserted into the inner perimeter of the screening screen plate, a fixing block is fixedly connected to the bottom end of the sliding rod, the fixing block is welded to the inner wall of the filter box, and a return spring is movably sleeved on the outer surface of the sliding rod below the screening screen plate, so that the sliding rod can limit the up and down shaking of the screening screen plate.

[0016] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0017] This utility model provides a terpineol extrusion filtration device for preparing conductive silver paste. A motor drives a turntable to rotate at a constant speed. The rotation of the turntable drives the brake block to rotate, which in turn drives the brake sleeve to move. The movement of the brake sleeve causes the pusher to move up and down reciprocally. This, in conjunction with the connecting rod, pushes the extrusion plate to move up and down reciprocally continuously, extruding the raw materials entering the extrusion chamber. During the extrusion process, a filter screen is used for preliminary filtration.

[0018] This invention provides a terpineol extrusion filtration device for preparing conductive silver paste. By setting a sieve screen plate to filter the filtered liquid again, when the brake sleeve moves, it drives the abutment rod to move up and down reciprocally. The other end of the abutment rod abuts against the sieve screen plate, causing it to move down on the outer surface of the slide rod and squeeze the return spring. When the abutment rod moves up, the sieve screen plate loses its driving force and rebounds to its original position under the elastic counter-pushing force of the return spring. This achieves up and down shaking and promotes filtration efficiency. Attached Figure Description

[0025] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model. Embodiments

[0026] As Figures 1-5As shown, the utility model provides a kind of terpilenol extrusion filter device for conductive silver paste preparation, including extrusion box 1, and the bottom end of extrusion box 1 is fixedly connected with filter box 2, and the periphery of extrusion box 1 is fixedly installed with support leg 3, and the rear side of extrusion box 1 is fixedly installed with feed inlet 4, and the inside of extrusion box 1 is provided with extrusion unit, and the inside of filter box 2 is provided with filter unit, and extrusion unit includes extrusion plate 11 movably installed in the inside of extrusion box 1, and the both sides of the outer surface of extrusion box 1 are fixedly installed with limit block 12, and the left side of the outer surface of filter box 2 is fixedly installed with motor 13, and the output end of motor 13 is fixedly connected with turntable 14, and the outer surface of one side of turntable 14 is fixedly connected with brake block 15, and the outer surface of brake block 15 movably sleeved with brake sleeve 16, and the top middle position of brake sleeve 16 is fixedly connected with push bracket 17, and the top bottom end of both sides of push bracket 17 is fixedly installed with connecting rod 18, and the other end of connecting rod 18 is fixedly installed in the top of extrusion plate 11, and the bottom of extrusion plate 11 is fixedly installed with filter screen plate 19 on the inner wall bottom end of extrusion box 1.

[0027] Further, the output end of motor 13 drives turntable 14 to rotate at a constant speed, the rotation of turntable 14 drives brake block 15 to rotate, brake block 15 drives brake sleeve 16 to move, the movement of brake sleeve 16 drives push bracket 17 to move up and down, and thus connecting rod 18 pushes extrusion plate 11 to move up and down repeatedly, to extrude the raw materials in the inside of extrusion box 1, and filter screen plate 19 filters the raw materials preliminarily during extrusion. Embodiment

[0028] As Figures 1-5 shown, on the basis of embodiment 1, the utility model provides a kind of technical scheme: preferably, filter unit includes sieve screen plate 23 movably installed in the inside of filter box 2, and the left side of the inner wall of filter box 2 is fixedly installed with flow guide plate 21, and the left side bottom end of filter box 2 is fixedly installed with leakage prevention groove 22, and the bottom end middle position of brake sleeve 16 is fixedly installed with abutting rod 110, and the other end of abutting rod 110 penetrates the left side through hole of filter box 2 and extends above sieve screen plate 23, and the inside of the periphery of sieve screen plate 23 is movably inserted with slide rod 24, and the bottom end of slide rod 24 is fixedly connected with fixed block 25, and fixed block 25 is welded on the inner wall of filter box 2, and the outer surface of slide rod 24 is movably sleeved with return spring 26 below sieve screen plate 23.

[0029] Furthermore, the filtered liquid enters the interior of the filter box 2 and is filtered again by the screening screen plate 23. When the brake sleeve 16 moves, it drives the abutment rod 110 to move up and down. The other end of the abutment rod 110 abuts against the screening screen plate 23, causing it to move down onto the outer surface of the slide rod 24 and squeeze the return spring 26. When the abutment rod 110 moves up, the screening screen plate 23 loses its driving force and rebounds to its original position under the elastic counter-driving force of the return spring 26. This achieves up and down shaking and promotes filtration efficiency.

[0030] The working principle of the terpineol extrusion filtration device for preparing conductive silver paste will be explained in detail below.

[0031] like Figures 1-5 As shown, during use, the feed inlet 4 introduces the terpineol raw material into the extrusion box 1. Then, the output end of the motor 13 drives the turntable 14 to rotate at a constant speed. The rotation of the turntable 14 drives the brake block 15 to rotate as well. The rotation of the brake block 15 drives the brake sleeve 16 to move as well. The movement of the brake sleeve 16 causes the push bracket 17 to move up and down reciprocally. This, together with the connecting rod 18, pushes the extrusion plate 11 to move up and down reciprocally continuously, extruding the raw material entering the extrusion box 1. During extrusion, it is initially filtered by the filter screen plate 19. The filtered liquid enters the filter box 2 and is filtered again by the screening screen plate 23. When the brake sleeve 16 moves, it drives the abutment rod 110 to move up and down reciprocally. The other end of the abutment rod 110 abuts against the screening screen plate 23, causing it to move down onto the outer surface of the slide rod 24 and press the return spring 26. When the abutment rod 110 moves up, the screening screen plate 23 loses its pushing force and rebounds to its original position under the elastic counter-pushing force of the return spring 26. This achieves up and down shaking, promoting filtration efficiency.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
