Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard production and processing technology, specifically a screening device for corrugated cardboard production and processing. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one corrugated core paper layer and one cardboard layer. In order to assist in the screening of pulp during the production and processing of corrugated cardboard, a screening device for corrugated cardboard production and processing is needed.

[0003] Traditional screening devices used in corrugated cardboard production typically include fine and coarse screens. These screens are used to assist in pulp filtration. However, to ensure stable filtration, a vibrating motor is added to the fine screen. After sieving inside the device, the fine and coarse screens are removed for cleaning, which affects the cleaning efficiency. Furthermore, traditional devices rely on a single stirring rod, making it difficult to ensure uniform pulp concentration. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a screening device for corrugated cardboard production and processing, thereby solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a screening device for corrugated cardboard production and processing, including a screening cylinder, a base frame fixedly mounted at the bottom of the screening cylinder, a motor fixedly mounted at the bottom of the inner wall of the base frame, a rotating rod fixedly sleeved on the output shaft of the motor, a base plate fixedly mounted on the top of the rotating rod, a scraper frame provided on the top of the base plate, a protrusion fixedly mounted on the top of the scraper frame, a fine screening plate slidably sleeved on the screening cylinder, a ring overlapping the top of the fine screening plate, a coarse screening plate threadedly connected to the screening cylinder, and a top cover slidably sleeved on the top of the screening cylinder.

[0006] As a preferred embodiment of this utility model, the screening cylinder is fixedly sleeved with a toothed ring, the bottom plate is rotatably sleeved with a transmission rod, the bottom of the transmission rod is fixedly fitted with a drive gear, and the convex teeth of the drive gear mesh with the convex teeth of the toothed ring, and the top of the transmission rod is fixedly fitted with a transmission gear.

[0007] As a preferred embodiment of this utility model, a rotating gear is rotatably connected to the top of the base plate, and the convex teeth of the rotating gear mesh with the convex teeth of the transmission gear. A connecting plate is fixedly connected to the top of the rotating gear, and the top of the connecting plate is fixedly assembled with the bottom of the scraper frame.

[0008] As a preferred technical solution of this utility model, the bottom of the fine sieve plate near the outer edge is provided with a groove, and the shape and size of the concave surface of the groove are adapted to the shape and size of the convex surface of the top of the protrusion. The bottom of the coarse sieve plate is rotatably connected to a connecting ring, and the bottom of the connecting ring is fixedly connected to a spring, and the bottom of the spring is fixedly connected to the top of the ring. The top of the coarse sieve plate is fixedly equipped with a handle.

[0009] As a preferred embodiment of this utility model, a positioning ring is fixedly fitted on the outer edge of the screening cylinder near the top. The positioning ring is slidably sleeved with the top cover. A fixing frame is fixedly fitted on the positioning ring. A second spring is fixedly connected to the fixing frame. A push plate is fixedly connected to the end of the second spring away from the inner wall of the fixing frame. The side of the push plate is slidably connected to the inner wall of the fixing frame. A pull rod is fixedly fitted on the side of the push plate. The outer edge of the pull rod is slidably sleeved with the inner wall of the fixing frame.

[0010] As a preferred embodiment of this utility model, a limiting rod is fixedly mounted on the side of the push plate, and the outer edge of the limiting rod passes through the inner wall of the positioning ring and slides in connection with the inner wall of the top cover. The top cover is fixedly fitted with a feed pipe, the bottom of the screening cylinder is fixedly fitted with a solenoid valve discharge pipe, and the screening cylinder is fixedly fitted with a support frame.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This screening device for corrugated cardboard production and processing uses a motor and a rotating rod in combination. The motor drives the base plate to rotate via the rotating rod, which in turn drives the drive gear to rotate within the inner wall of the toothed ring. The toothed ring assists the drive gear in rotating, while the drive gear drives the transmission gear via the transmission rod. The transmission gear then drives the rotating gear to rotate, and the rotating gear drives the scraper via the connecting plate. The scraper assists in cleaning the inner wall of the screening cylinder while also helping to evenly mix the pulp inside the screening cylinder.

[0013] 2. This screening device for corrugated cardboard production and processing uses a scraper frame and a protrusion in cooperation. The scraper frame drives the protrusion to move, and then the outer edge of the protrusion moves with the bottom of the fine screen plate and the inner wall of the groove, thereby assisting the fine screen plate to slide on the inner wall of the screening cylinder. A spring pushes the ring at the bottom of the connecting ring to move the fine screen plate down and reset, thereby assisting the pulp to accumulate on the inner wall of the fine screen plate for vibration feeding.

[0014] 3. The screening device for corrugated cardboard production and processing uses a coarse screen plate and a connecting ring in combination. The gripping rod drives the coarse screen plate to rotate in the inner wall of the screening cylinder, thereby assisting the separation of the coarse screen plate from the screening cylinder and the separation of the bottom of the ring from the top of the fine screen plate. Then, the fine screen plate is moved away from the inner wall of the screening cylinder, thereby assisting the rapid disassembly of the coarse screen plate and the fine screen plate.
