Description

Technical Field

[0001] This invention relates to the technical field of building material processing, and specifically to a screening device for building materials. Background Technology

[0002] As an important component of building materials, ceramic tiles serve both functional and decorative purposes in the construction industry. During processing, the glaze of ceramic tiles needs to be sieved. However, sometimes the glaze itself is of poor quality, containing impurities or particles, which easily cause clumping. Therefore, the clumped glaze needs to be broken up for better sieving. When the glaze contains a large amount of iron filings, it affects the aesthetic appearance of the tiles, so these iron filings need to be collected. Current technology uses magnets to adsorb the iron filings from the glaze. However, if the iron filings adsorbed by the magnet cannot be removed in time, the outer side of the magnet may lack sufficient suction, causing the iron filings to easily fall back into the glaze or become difficult to adsorb from the glaze. Summary of the Invention

[0003] The purpose of this invention is to provide a screening device for building materials to overcome the above-mentioned defects in the prior art.

[0004] A screening device for building materials includes a screening device body, a crushing and turning mechanism and an iron filings collection mechanism. The screening device body is provided with a mounting frame, a cylinder is provided on the top of the mounting frame, and a lifting plate is provided at the lower end of the piston rod of the cylinder.

[0005] The crushing and turning mechanism is located at the bottom of the lifting plate and is used to crush the lumpy glaze and turn the crushed glaze.

[0006] The iron filings collection mechanism scrapes and collects the iron filings adsorbed on the magnetic plate under the action of the moving plate of the crushing and turning mechanism.

[0007] Preferably, the crushing and turning mechanism includes a motor, a crushing plate, and a turning plate. Two motors are provided and symmetrically arranged at both ends of the top of the lifting plate. The lower end of the output shaft of the motor is connected to a drive disc. A drive plate is rotatably connected to the eccentric part at the bottom of each drive disc. The two ends of the crushing plate are respectively hinged to the ends of the drive plate by pins. The moving plate is slidably connected to the bottom of the lifting plate and is slidably connected to the crushing plate by a slider. The two ends of the moving plate are symmetrically provided with connecting rods that are perpendicular to the moving plate. Several turning plates are evenly distributed on each connecting rod.

[0008] Preferably, the iron filings collection mechanism includes a guide plate and a collection opening and closing assembly. The magnetic plate is disposed on the side of the rolling plate and located in the slider. The inner walls of the slider are symmetrically provided with guide plates in the shape of an "eight". The collection opening and closing assembly is disposed in the slider so that iron filings can be collected. The lower side of the slider is connected to a dust pump through a suction pipe.

[0009] Preferably, the material collection opening and closing assembly includes a sealing plate, a sliding rod, a rotating block, and a spring. The sealing plate is hinged to the middle of the slider by a pin, and the rotating block is rotatably connected to the slider by a pin. One end of the sliding rod is hinged to a side block on the sealing plate by a pin, and the other end is slidably inserted into the rotating block. The spring is sleeved on the sliding rod. The slider has symmetrically arranged baffles on both sides of the sealing plate, and the rolling plate has driving rods on both sides of the magnetic plate to drive the sealing plate to rotate and change position.

[0010] Preferably, several arc-shaped rolling blocks are evenly distributed along the bottom of the rolling plate.

[0011] Preferably, the lifting plate has guide rods symmetrically provided at both ends, which are slidably connected to the mounting frame.

[0012] The present invention has the following advantages:

[0013] 1. This invention uses a motor to drive the crushing and turning mechanism to swing the crushing block at the bottom of the crushing plate, crushing the glaze clumps on the screen. At the same time, the crushing plate drives the moving plate to move left and right, turning the glaze and making it easier to turn the glaze at the bottom to the top, thus facilitating the crushing of buried clumps. While the moving plate slides on the crushing plate, the material is collected unidirectionally by the figure-eight guide plate in the material collection opening and closing assembly, guiding the iron filings adsorbed on the magnetic plate to the slider. The iron filings are then collected by the suction of the dust pump, thus enabling timely collection of iron filings.

[0014] 2. The sealing plate of the material collection opening and closing assembly guides the slider in one direction, scraping the iron filings adsorbed on the magnetic plate along the guide plate and sealing plate into the slider for collection. While guiding the material, the baffle and spring keep the sealing plate stable. When the drive rod on the rolling plate drives the sealing plate to rotate, it rotates the sealing plate to the other side. When the slider moves in the opposite direction, it scrapes and collects the iron filings adsorbed on the magnetic plate again. Through the continuous displacement of the sealing plate in both directions, the slider can scrape and collect the adsorbed iron filings during the reciprocating motion of the magnetic plate, improving the iron filings collection efficiency.

Detailed Implementation

[0025] The following detailed description of the embodiments, with reference to the accompanying drawings, will further illustrate the specific implementation of the present invention, in order to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the concept and technical solutions of the present invention.

[0026] like Figure 1-8 As shown, the present invention provides a screening device for building materials, including a screening device body 1, a crushing and turning mechanism 5, and an iron filings collection mechanism 6. The screening device body 1 is provided with a mounting frame 2, and a cylinder 3 is provided on the top of the mounting frame 2. A lifting plate 4 is provided at the lower end of the piston rod of the cylinder 3. Guide rods 41 that are slidably connected to the mounting frame 2 are provided at both ends of the lifting plate 4. The symmetrical guide rods 41 make the lifting plate 4 rise and fall more smoothly. The crushing and turning mechanism 5 is located at the bottom of the lifting plate 4 and is used to crush the lumpy glaze and turn the crushed glaze. The iron filings collection mechanism 6 scrapes off and collects the iron filings adsorbed on the magnetic plate 61 under the action of the moving plate 51 of the crushing and turning mechanism 5.

[0027] It should be noted that the crushing and turning mechanism 5 includes a motor 52, a crushing plate 55, and a turning plate 58. There are two motors 52, which are symmetrically arranged at both ends of the top of the lifting plate 4. The lower end of the output shaft of the motor 52 is connected to a drive disk 53. A drive plate 54 is rotatably connected to the bottom eccentric part of each drive disk 53. The two ends of the crushing plate 55 are respectively hinged to the ends of the drive plate 54 by pins. Several arc-shaped crushing blocks 551 are evenly distributed along the bottom of the crushing plate 55. The crushing blocks 551 crush the lumpy glaze. The moving plate 51 is slidably connected to the bottom of the lifting plate 4. The moving plate 51 is slidably connected to the crushing plate 55 by a slider 56. The two ends of the moving plate 51 are symmetrically provided with connecting rods 57 that are perpendicular to the moving plate 51. Several turning plates 58 are evenly distributed on each connecting rod 57.

[0028] In addition, the iron filings collection mechanism 6 includes a guide plate 62 and a collection opening and closing assembly 63. The magnetic plate 61 is disposed on the side of the rolling plate 55 and located in the slider 56. The inner walls of the slider 56 are symmetrically provided with guide plates 62 in the shape of an "eight". The collection opening and closing assembly 63 is disposed in the slider 56 so that iron filings can be collected. The lower side of the slider 56 is connected to a dust pump through a suction pipe.

[0029] In addition, the material collection opening and closing assembly 63 includes a sealing plate 631, a sliding rod 633, a rotating block 632, and a spring 634. The sealing plate 631 is hinged to the middle of the slider 56 by a pin. The rotating block 632 is rotatably connected to the slider 56 by a pin. One end of the sliding rod 633 is hinged to the side block 637 on the sealing plate 631 by a pin, and the other end is slidably inserted into the rotating block 632. The spring 634 is sleeved on the sliding rod 633. The slider 56 has symmetrically arranged baffles 635 on both sides of the sealing plate 631. The rolling plate 55 has driving rods 636 on both sides of the magnetic plate 61 to drive the sealing plate 631 to rotate and change position. Through the material collection opening and closing assembly 63, the sealing plate 631 is automatically rotated, so that the iron filings collection mechanism 6 can collect iron filings and impurities in one direction.

[0030] Detailed implementation methods and principles:

[0031] In practical application, the glaze is placed on the sieve disc in the main body 1 of the sieving device, and the piston rod of the cylinder 3 is extended to move the lifting plate 4 downward, so that the crushing and turning mechanism 5 contacts the sieve disc. Then, the motor 52 is started, and the output shaft of the motor 52 drives the drive disc 53 to rotate. The drive plate 54 on the drive disc 53 drives the crushing plate 55 to swing. The crushing block 551 at the bottom of the crushing plate 55 crushes the glaze clumps on the sieve disc. At the same time, the crushing plate 55 drives the moving plate 51 to move left and right and slide on the crushing plate 55. The turning plate 58 on the connecting rod 57 turns the glaze, so that the glaze can be screened more thoroughly. The magnetic plate 61 on the side of the crushing plate 55 attracts iron filings in the glaze. While plate 51 slides on the rolling plate 55, guide plate 62 and sealing plate 631 in slider 56 guide the iron filings adsorbed on magnetic plate 61 into slider 56. In addition, the stop bar 635 on one side of sealing plate 631 limits sealing plate 631. Then, the suction of the dust pump collects the iron filings. When slider 56 moves to the end of rolling plate 55, drive rod 636 squeezes the upper side of sealing plate 631, causing sealing plate 631 to rotate. This causes the stop bar 635 on the other side of sealing plate 631 to limit sealing plate 631, thereby blocking the guide plate 62 on the other side. Then slider 56 begins to move towards the other side of rolling plate 55 to scrape off and collect the iron filings re-adsorbed on magnetic plate 61.

[0032] In summary, the present invention uses a motor 52 to drive the crushing block 551 at the bottom of the crushing and turning mechanism 5 to swing, crushing the glaze clumps on the screen. At the same time, the crushing plate 55 drives the moving plate 51 to move left and right, turning the glaze and making it easier to turn the glaze at the bottom to the top, thus facilitating the crushing of buried clumps. While the moving plate 51 slides on the crushing plate 55, the material is collected unidirectionally by the figure-eight guide plate 62 in the material collection opening and closing assembly 63, so that the iron filings adsorbed on the magnetic plate 61 are guided to the slider 56, and the iron filings are collected by the suction of the dust pump, thus enabling timely collection of iron filings.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the present invention and technical solution to other situations without modification, are all within the protection scope of the present invention.
