Description

Technical Field

[0001] The utility model relates to the field of roller kilns, and particularly relates to a cover-taking mechanism for a roller kiln. Background Art

[0002] A roller kiln, namely an archless kiln, is a tunnel kiln with a long and narrow cross-section. It consists of a series of rollers arranged in parallel and crossing the cross-section of the working channel of the kiln to form a "roller track". The products are placed on the roller track and conveyed into the kiln as the rollers rotate, and the firing process is completed in the kiln. During the firing process, to prevent the damage and pollution of the green body and glaze surface by gases and harmful substances, the materials are placed in a container made of refractory materials for roasting, and this container is called a sagger.

[0003] After the sagger is subjected to high-temperature treatment in the furnace body, the sagger cover needs to be removed, and then the materials in the sagger are extracted by vacuum. In the related art, the cover-taking mechanism generally has a high degree of integration, which is beneficial to reducing the volume of the mechanism and improving the efficiency. However, the overall mechanism has a high degree of correlation, resulting in a decrease in the stability of a single driving unit, and the driving unit is a driving mechanism that performs linear motion in one direction.

[0004] Therefore, it is urgent to design a cover-taking mechanism for a roller kiln to solve the technical problem of insufficient stability of a single driving unit. Content of the Utility Model

[0008] Further, the moving direction of the movable end of the translation driving unit is horizontally arranged;

[0009] The moving direction of the movable end of the vertical driving unit is vertically arranged.

[0010] Further, the clamping component is provided with a plurality of guide rods, and the guide rods are slidably connected to the mounting plate;

[0011] The guide rods are arranged in parallel with the movable end of the vertical driving unit.

[0012] Further, a plurality of linear bearings are mounted on the mounting plate, and the linear bearings are sleeved on the corresponding guide rods.

[0029] The present utility model will now be further described in detail with reference to the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0030] In the related art, the mechanism for removing the lid of a roller hearth kiln generally has a high degree of integration, which is beneficial to reducing the volume of the mechanism and improving efficiency. However, the high correlation of the overall mechanism results in a decrease in the stability of a single drive unit.

[0031] To solve the above problems, as Figure 1 shown, at least one embodiment provides a lid-removing mechanism for a roller hearth kiln, including: a mounting plate 1, on which a translation drive unit 2 and a vertical drive unit 3 are separately arranged. The translation drive unit 2 is fixedly installed inside the whole roller hearth kiln equipment, and its movable end is connected to the mounting plate 1, and the moving direction of the movable end of the translation drive unit 2 is horizontally arranged. The translation drive unit 2 is used to drive the lid-removing mechanism of the roller hearth kiln to move horizontally along the moving direction of its movable end. The moving direction of the movable end of the vertical drive unit 3 is vertically arranged, and a clamping component 4 is installed at the movable end of the vertical drive unit 3. The vertical drive unit 3 is used to drive the clamping component 4 to move vertically along the moving direction of its movable end, and the clamping component 4 is used to clamp the sagger lid. Optionally, the translation drive unit 2 is a retracting cylinder, and the vertical drive unit 3 is a driving cylinder. The above setting separately arranges the translation drive unit 2 and the vertical drive unit 3, that is, forms two independent drive units in horizontal and vertical directions, so as to reduce the overall correlation and further ensure the stability of a single drive unit.

[0032] To achieve the effect of the clamping component 4 clamping the sagger lid, as Figure 3 shown, in at least one embodiment, the clamping component 4 has a plurality of guide rods 41, the guide rods 41 are slidably connected to the mounting plate 1, and are arranged parallel to the movable end of the vertical drive unit 3, that is, vertically arranged. The guide rods 41 can ensure that the clamping component 4 moves vertically under the drive of the vertical drive unit 3 without deviation. To reduce the frictional resistance when the guide rods 41 move, as Figure 2 shown, a plurality of linear bearings 11 are installed on the mounting plate 1, and the linear bearings 11 are sleeved on the guide rods 41, which can reduce the frictional resistance when the guide rods 41 move. The guide rods 41 and the linear bearings 11 are in one-to-one correspondence, that is, one linear bearing 11 is sleeved on one guide rod 41. Preferably, the number of guide rods 41 is 4, so the number of linear bearings 11 is also 4, further enhancing the stability. The clamping component 4 further includes a clamping cylinder 43 and a plurality of clamping claws 44. The clamping cylinder 43 is used to drive the clamping claws 44 to expand and contract to clamp or release the sagger lid. The movable end of the clamping cylinder 43 is connected to each clamping claw 44, and the clamping claws 44 are uniformly arranged along the axis of the clamping cylinder 43 to ensure stability during clamping. The outer surface of the clamping claws 44 has an oxide layer, which prevents the clamping claws 44 from being contaminated and corroded when contacting the material during clamping the sagger lid, and extends the service life of the clamping claws 44.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
