Description

Technical Field

[0001] This utility model relates to the field of discharge port technology, specifically a dry grinding discharge port. Background Technology

[0002] Ceramic substrates are crucial carriers for the production of DBC ceramic copper-clad laminates. The production of ceramic substrates requires the preparation of ultrafine alumina powder, which is currently primarily produced using dry grinding. After dry grinding, the sealed dry grinding outlet cover is replaced with a perforated outlet. This is to effectively separate the dry-ground powder from the ceramic balls and reduce the discharge rate, thereby effectively controlling excessively rapid discharge that could lead to severe dust generation and negatively impact the environment and worker health.

[0003] However, the existing dry grinding outlet is not convenient for opening and closing the baffle in actual use, and the operation is complicated and troublesome. To address this problem, a dry grinding outlet is provided. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 4This utility model provides a technical solution: a dry grinding outlet, including a discharge pipe 1, a microporous plate 2 fixedly embedded in the inner cavity of the discharge pipe 1, a baffle 3 slidably inserted into the inner cavity of the discharge pipe 1, a frame 4 provided at the front end of the discharge pipe 1, a sliding assembly provided in the inner cavity of the frame 4, and two connecting rods 5 provided on the sliding assembly. The ends of the two connecting rods 5 that are far apart from each other are respectively fixedly connected to the two baffles 3. Through the setting of the sliding assembly, the two connecting rods 5 can drive the two baffles 3 to slide relative to each other at the same time, thereby facilitating the opening and closing of the baffles 3. The operation is simple and convenient, solving the problem that the existing dry grinding outlet is not convenient to open and close the baffles 3 in actual use, and the operation is complicated and troublesome. Through the setting of the microporous plate 2, the dry grinding powder and ceramic balls can be effectively separated, and the discharge speed can be reduced, thereby effectively controlling the serious dust pollution caused by excessive discharge, which affects the environment and the health of workers.

[0020] In this embodiment, the sliding assembly includes a lead screw 6, a guide rod 7, a sliding plate 8, and a drive assembly. The lead screw 6 is rotatably connected to the inner cavity of the frame 4 via bearings. The guide rod 7 is located in the inner cavity of the frame 4 and is parallel to the lead screw 6. The two sliding plates 8 are respectively screwed to the left and right sides of the outer wall of the lead screw 6 and are slidably sleeved on the left and right sides of the outer wall of the guide rod 7. The drive assembly is located at the front end of the discharge pipe 1 and is fixedly sleeved on the middle of the outer wall of the lead screw 6. The drive assembly drives the lead screw 6 to rotate, thereby generating relative thread rotation force on the opposite threads on the left and right sides of the outer wall of the lead screw 6. Under the limiting action of the guide rod 7, the two sliding plates 8 slide relative to each other simultaneously. This allows the two connecting rods 5 to drive the two baffles 3 to slide relative to each other simultaneously, which facilitates the control of the opening and closing of the baffles 3. The operation is simple and convenient, solving the problem that the existing dry grinding discharge port is inconvenient to open and close the baffles 3 in actual use, and the operation is complicated and troublesome.

[0021] In this embodiment, the threads on the left and right sides of the outer wall of the lead screw 6 are arranged opposite to each other, so that when the lead screw 6 rotates, the left and right sides of its outer wall generate relative thread rotational forces, and the two slide plates 8 slide relative to each other simultaneously under the limiting action of the guide rod 7.

[0022] In this embodiment, the driving assembly includes a gear 9, a limiting assembly, a rack 12, a connecting plate 11, and a cylinder 10. The gear 9 is fixedly sleeved on the middle of the outer wall of the lead screw 6. The cylinder 10 is fixedly installed at the front end of the discharge pipe 1. The connecting plate 11 is located at the output end of the cylinder 10. The rack 12 is located at the top of the connecting plate 11. The limiting assembly is located at the front end of the discharge pipe 1 and is fixedly connected to the rack 12. The output end of the cylinder 10 drives the connecting plate 11 to slide, thereby causing the rack 12 to slide along a straight line under the limiting action of the limiting groove 13 and the limiting block 14. Since the gear 9 meshes with the rack 12, when the rack 12 slides, the gear 9 can drive the lead screw 6 to rotate.

[0023] In this embodiment, rack 12 meshes with gear 9.

[0024] In this embodiment, the limiting component includes a limiting groove 13 and a limiting block 14. The limiting groove 13 is opened at the front end of the discharge pipe 1, and the limiting block 14 is slidably embedded in the inner cavity of the limiting groove 13 and fixedly connected to the rack 12.

[0025] In this embodiment, the inner cavity of the limiting groove 13 and the outer wall of the limiting block 14 are adapted to each other and are both in the shape of a "T".
