Description

Technical Field

[0001] The utility model belongs to the technical field of screening equipment, in particular to a raw material screening device for floor tile production. Background Art

[0002] Ceramic tile raw material screening is an important part of the ceramic tile production process. It mainly uses screening equipment to screen the raw materials to remove impurities and particles that do not meet the requirements, ensuring the quality and stability of the raw materials.

[0003] After searching, the publication (announcement) number CN219745473U discloses a "blank screening device", which includes a screening mechanism, wherein a chip removal assembly is fixedly installed on the top of the screening mechanism, and the screening mechanism includes an outer frame, a screening shell, a material receiving bottom frame, a material discharge pipe 2, a driving motor and a feeding frame. By adding the chip removal assembly, the rotating motor can drive the rotating rod and a plurality of magnetic blocks to rotate. During the rotation process, the outer side of the magnetic block contacts the blank, thereby continuously absorbing iron chips mixed in the ceramic blank. The magnetic block that absorbs the iron chips continues to rotate with the rotating rod. When the magnetic block rotates to the top of the scraper, the magnetic block continues to rotate downward, and the scraper can scrape off the iron chips adsorbed on the outer side of the magnetic block. The scraped iron chips slide along the inclined scraper into the dust collecting frame. The device removes the iron chips mixed in the blank more cleanly, effectively improving the screening quality and screening efficiency of the ceramic blank and other beneficial effects;

[0004] Since the raw materials need to be crushed in the feeding frame and then screened through the screening plate, a large amount of dust will be generated in the above process, affecting the working environment. At the same time, the inhalation of dust will also cause damage to the human respiratory system, nervous system, skin, eyes, etc.

[0005] In order to solve the above problems, this application proposes a raw material screening device for floor tile production. Utility Model Content

[0031] Among them, the driving components include a screw 9 installed on the side of the feeding frame 2 through a bracket and an internal thread block 10 arranged outside the screw 9, as well as a linkage rod 11 hinged between the internal thread block 10 and the protective cover 4. The screw 9 is threadedly connected to the internal thread block 10, and the two protective covers 4 are respectively connected to the internal thread block 10 through the linkage rod 11. A servo motor 18 with an output end connected to the screw 9 is also fixedly mounted on the feeding frame 2. In this embodiment, the synchronous opening and closing of the two protective covers 4 can be achieved by driving the servo motor 18, thereby realizing automation. While ensuring the effect, it is convenient for the staff to operate, and the forward and reverse rotation of the servo motor 18 can be directly operated by the button.

[0032] Among them, a pipe clamp 15 for fixing the dust suction branch pipe 5 is fixed at the bottom of the protective cover 4, and a dust suction main pipe 16 is connected to the dust suction branch pipe 5. The dust suction main pipe 16 passes through the side baffle 8, and the dust suction main pipe 16 passes through the bottom of the side baffle 8 and is provided with a dust suction connector 17 connected to the hose of the dust suction equipment. In this embodiment, multiple groups of dust suction branch pipes 5 and dust suction covers 6 are evenly distributed at the bottom of the protective cover 4. When the protective cover 4 is closed inside the feeding frame 2, a uniform dust suction space is formed above the crushing, which plays a uniform and efficient dust suction role.

[0033] Among them, a slide rail 12 is fixedly provided at the bottom of the protective cover 4, a support 13 is fixed at the top outside the feeding frame 2, a slide 14 is fixed at the upper end of the support 13, and the slide rail 12 slides on the support 13. In this embodiment, the slide rail 12 and the slide 14 ensure the stable opening and closing of the protective cover 4. At the same time, the slide 14 arranged on the outside can ensure the opening range of the protective cover 4, which is convenient for adding raw materials.

[0034] Among them, the dust suction branch pipe 5 and the dust suction hood 6 move between the inside and the outside of the feeding frame 2 through the open groove 7. In this embodiment, the open groove 7 plays a role in avoiding the movement of the dust suction branch pipe 5 and the dust suction hood 6, avoiding collision with the dust suction branch pipe 5 and the dust suction hood 6 during the feeding process, and making the dust suction component more flexible to use.

[0035] Among them, a sealing gasket 19 is provided on the side of the two protective covers 4 that are close to each other. In this embodiment, the sealing gasket 19 can not only have a sealing effect, but also have a buffering effect to avoid mutual impact when the two protective covers 4 are closed and avoid the generation of noise.

[0036] It can be understood that the protective cover 4 provided first can prevent the fragments inside the feeding frame 2 from splashing, and at the same time can also suppress the diffusion of dust. The protective cover 4 is also opened and closed automatically by the driving component. Secondly, the dust collection component provided can collect the dust generated by crushing and screening, and avoid the harm caused by a large amount of dust to the human body and the environment.

[0037] A specific application of this embodiment is: the dust suction connector 17 is connected to the external dust suction equipment through a hose. When raw materials need to be added to the inside of the feeding frame 2, the servo motor 18 drives the screw 9 and the internal thread block 10 to spiral. The internal thread block 10 moves toward the upper end of the screw 9 through the moving force of the spiral. At this time, the internal thread block 10 drives the two protective covers 4 at the upper end of the feeding frame 2 to slide to both sides at the same time through the linkage rod 11, and the slide rail 12 follows the sliding outside of the slide seat 14. During the movement of the protective cover 4, the side baffle 8 disengages from the open groove 7, and the dust suction branch pipe 5 and the dust suction hood 6 move to the outside of the feeding frame 2 through the open groove 7. Ceramic tile production raw materials are added to the inside of the feeding frame 2, and the servo motor 18 is driven in the reverse direction to drive the protective cover 4 to close at the upper end of the feeding frame 2. At this time, the dust suction branch pipe 5 and the dust suction hood 6 are located directly above the inside of the feeding frame 2;

[0038] The crushing roller 3 is driven to perform crushing work, and the screening body 1 performs screening work at the same time. The dust generated by crushing is located in the feeding frame 2, and the dust generated by screening is located in the screening cabin. At this time, the external dust collection device is working and the dust collection device is inhaling air. At this time, the discharge port after screening on the screening body 1 serves as the air inlet end, and air is inhaled from the discharge port. The dust generated by screening and crushing passes through the feeding frame 2, and then under the action of the dust collection device, the dust is sucked away through the dust collection hood 6, the dust collection branch pipe 5, and the dust collection main pipe 16.
