Description

Technical Field

[0001] This invention relates to the field of ceramic carrier processing technology, and in particular to a feeding system suitable for air drying ovens. Background Technology

[0002] The air drying oven (drying oven) is mainly used for drying ceramic carriers (gasoline and diesel catalysts) after coating, and is used in conjunction with temperature and action control systems.

[0003] Before the ceramic carrier is dried in the air drying oven, it needs to be transferred manually or by a robot to the loading platform 100 and then conveyed to the input mesh belt assembly 200 inside the air drying oven.

[0004] Manual transfer is time-consuming and labor-intensive, and the placement is not fixed, which can easily increase the difficulty of subsequent unloading.

[0005] Using robots to transfer ceramic carriers one by one is relatively inefficient, but it allows for easy and flexible adjustment of the spacing between the carriers. This enables the carriers to be placed in accordance with the airflow pattern inside the drying oven, and the spacing between the carriers can be adjusted to a state more conducive to drying (such as staggered placement or unequal spacing), thus achieving better drying results. Transferring multiple carriers at once is more efficient but less flexible, as it is difficult to easily adjust the spacing between the carriers.

[0006] Therefore, a feeding system suitable for drying ovens is needed that allows for convenient and flexible adjustment of the spacing between ceramic carriers to be transferred to the input mesh belt assembly 200. Summary of the Invention

[0007] This application provides a feeding system suitable for air-drying ovens, which solves the technical problems of relatively low efficiency in transferring ceramic carriers by using robots to pick them up one by one in the prior art, and the technical problems of the inability to adjust the spacing between ceramic carriers placed in batches on the loading platform; it achieves the technical effect that the feeding system suitable for air-drying ovens can conveniently and flexibly adjust the spacing between ceramic carriers to be transferred to the input mesh belt assembly in batches.

A strip of thin iron plate is set on one of the L-shaped plates. By squeezing the strip of thin iron plate, its deformation causes the ceramic carrier on it to move. This effectively solves the technical problems of relatively low efficiency in transferring ceramic carriers by using robots to pick them up one by one in the existing technology, and the technical problems of the inability to adjust the spacing between ceramic carriers placed in batches on the loading platform. Thus, a feeding system suitable for air-drying ovens can conveniently and flexibly adjust the spacing between ceramic carriers to be transferred to the input mesh belt assembly in batches.

The distance between the side of the cylindrical rotating column 521 furthest from the rectangular frame 520 and the U-shaped surface of the rectangular frame 520 is less than 3 mm. The cylindrical rotating columns 521 have built-in magnets.

[0087] The rectangular frame 520 is also provided with a soft iron strip 522 and a strip winding assembly 523.

[0088] The soft iron strip 522 is an iron strip with a thickness of less than 3 mm, a length greater than 1.6 times the length of the rectangular frame 520, and a width 0.6 to 0.95 times the length of the cylindrical rotating column 521.

One end is fixed to the end of the rectangular frame 520, and the other end is positioned on the strip winding assembly 523 located at the other end of the rectangular frame 520. The soft iron strip 522 is located on the side of the soft iron strip 522 close to the receiving plate 510.

[0127] Furthermore, the insertion fixing assembly 735 includes a positioning block 736 and a sliding cone 737; the positioning block 736 is fixed to the side wall of the base rod 732 near the top, and the positioning block 736 has a horizontally arranged groove inside, in which the iron sliding cone 737 is slidably positioned; a compression spring is also positioned between the sliding cones 737; under normal conditions, the sliding cone 737 is pushed outward and inserted into the insertion hole 734 under the elastic force of the compression spring;

[0128] The power telescopic column 750 is provided with an adsorption body 751 at the same height as the insertion fixing component 735. The adsorption body 751 is an electromagnet, which adsorbs the sliding cone 737 in the energized state to overcome the spring force of the compression spring.

[0129] A toggle lever 752 is also positioned on the side wall of the power telescopic column 750. The toggle lever 752 is a rigid rod in the shape of a U-shape. It is rotatably connected to the side wall of the power telescopic column 750 and rotates under the coordinated action of the control unit and the power component. The rotation angle is 30 to 75 degrees. It is used to drive the sliding lifting column 730 to slide by resisting and squeezing it.

[0130] When the feeding system of the air-drying oven in the embodiments of this application is actually used:

[0131] After the rotating rod 752 is rotated, the single sliding lifting column 730 is moved to slide. The power telescopic column 750 extends and lifts the sliding rod 733 upward. The relative movement between the base rod 732 and the sliding rod 733 is controlled by the insertion fixing component 735 to see if it is locked. After the sliding cone 737 is pulled out of the insertion hole 734, it will automatically fall under its own weight when there is no power telescopic column 750 lifting it.

[0132] Example 3

[0133] To further improve the uniformity of drying the ceramic carriers, after a single drying cycle, the rows of ceramic carriers are controlled to return to the first rotating plate assembly 500. Then, by controlling the operation of the lifting column assembly 700, the soft iron belt 522 is bent and deformed, causing the ceramic carriers on the soft iron belt 522 to roll 90 to 180 degrees (by controlling the sliding lifting column 730 to slide and extend, the soft iron belt 522 forms multiple inclined surfaces, thus causing the ceramic carriers to roll). Finally, they are sent back into the drying oven for drying to ensure uniformity of drying.

[0134] Example 4

[0135] To further enhance the air-drying effect of the ceramic carrier and ensure the uniformity of drying, this application embodiment optimizes and improves the structure of the support frame 400 based on the above embodiment, specifically as follows:

[0136] like Figures 13 to 15As shown, a lifting telescopic body 410 is fixed to the bottom of the bearing frame 400, a support frame 430 is fixed to the side wall, and a conveyor belt assembly 420 is fixed to the support frame 430 near the top.

[0137] The supporting frame 400 and the supporting frame 110 are not fixed together;

[0138] The lifting telescopic body 410 is a longitudinally arranged electric telescopic rod, with its bottom fixed to the ground and its top fixed to the bottom of the support frame 430; the lifting telescopic body 410 extends and retracts under the control of the control unit to adjust the height of the conveyor belt assembly 420.

[0139] The supporting frame 430 is a plate-shaped, rod-shaped, or frame structure, fixed to the side wall or top of the bearing frame 400, and has a height greater than 30 cm.

[0140] The conveyor belt assembly 420 is a mesh belt conveyor structure with a trapezoidal longitudinal section that is larger at the top and smaller at the bottom. When the conveyor belt assembly 420 moves downward, it connects the mesh belt conveyor body 120 with the input mesh belt assembly 200, and the ceramic carrier can move smoothly from the mesh belt conveyor body 120 to the input mesh belt assembly 200.

[0141] Furthermore, the conveyor belt assembly 420 includes a side support body 421, a rotating support column 422, and a tubular belt body 423; the side support body 421 is a horizontally arranged rigid rod fixed on the support frame 430; the rotating support column 422 consists of multiple horizontally arranged cylindrical rods that operate under the coordinated action of the control unit and the power assembly; the rotating support column 422 is horizontally arranged, and its length direction is the same as the axial direction of the mesh belt conveyor 120; the tubular belt body 423 is a tubular mesh that is fitted and tightly attached to each cylindrical rod.

[0142] When the feeding system of the air-drying oven in the embodiments of this application is actually used:

[0143] After air drying (drying) for a certain period of time, the ceramic carrier is controlled to return to the loading platform 100 via the first rotating plate assembly 500 and the second rotating plate assembly 600, thereby causing the ceramic carrier to flip over; then the first rotating plate assembly 500 and the second rotating plate assembly 600 are controlled to rotate, and the conveyor belt assembly 420 is controlled to move downward; finally, the ceramic carrier transferred back to the loading platform 100 is returned to the input mesh belt assembly 200 via the conveyor belt assembly 420 for air drying.

[0144] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
