Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of density fiberboard production equipment, specifically to a burning wire conveying device for a pad return system. Background Technology
[0002] In the production of high-density fiberboard (HDF), a backing board (with a mesh lining on top) receives the board blanks transported from upstream. Both boards undergo a hot-pressing process in a hot press to form the final board shape. The backing board is then separated from the backing board structure and transported downstream. The separated backing board structure then enters the backing board return system to receive the board blanks again, and the cycle repeats. However, over time, some stubborn fiber impurities may remain on the mesh lining, which cannot be removed by ordinary tapping. This requires workers to use a blowtorch to burn off the fiber impurities on the backing board mesh during transport in the backing board recycling system (mesh burning operation). However, since the backing board return system is constantly running, workers must walk alongside the backing board with the blowtorch, burning as they go. After burning, the backing board must be tapped a few times to remove any residue, resulting in tedious, laborious, and dangerous cleaning work. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a burning mesh conveying device for a pad return system. The pad cleaning is relatively easy and safe, with low labor intensity, stable pad conveying, simple structure, and low modification cost, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a wire mesh conveying device for a pad return system, comprising a conveyor 1 and a conveyor 2 arranged sequentially. The conveyor 1 is equipped with a wire mesh roller platform, which includes multiple sets of bearing supports mounted on the frame of the conveyor 1. A wire mesh support roller is provided between each set of bearing supports. The wire mesh support roller is horizontally arranged and perpendicular to the conveying direction of the conveyor 1. The multiple wire mesh support rollers are arranged along the conveying direction of the conveyor 1, and the support surface at the top of each wire mesh support roller is higher than that of the conveyor 1. The conveyor 2 is equipped with a blowing device, which includes a support frame mounted on the frame of the conveyor 2. A guide hood is fixedly mounted on the support frame. The air outlet of the guide hood faces downward and is located above the conveyor 2. The guide hood has an inverted truncated pyramid structure. A fan bracket is fixedly mounted at the center of the top of the guide hood. Centrifugal fans are symmetrically fixed on both sides of the fan bracket, and the inlet end of each centrifugal fan is connected to the top of the guide hood.
[0005] Furthermore, the bottom opening width of the air guide hood is adapted to the conveying width of the second conveyor, and an air guide plate is provided on the left side of the bottom opening of the air guide hood, and the air guide plate is inclined downward to the right.
[0006] Furthermore, both conveyor one and conveyor two are chain conveyors. Conveyor two includes conveyor chains symmetrically arranged on the front and rear sides of its frame. Each link of the conveyor chain is equipped with a support plate for supporting the pad. The support plate has an inverted U-shaped structure, and the top surface of the support plate is provided with anti-slip protrusions. U-shaped steel is horizontally arranged on the frame of conveyor two at the corresponding positions of the conveyor chains.

Detailed Implementation
[0011] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0012] Please see Figure 1-7 This utility model provides a technical solution: a wire mesh conveying device for a pad return system, comprising a conveyor 1, a conveyor 5, and a conveyor 2 arranged sequentially. The conveyor 1 is equipped with a wire mesh roller platform 3, which includes multiple sets of bearing supports 31 mounted on the frame of the conveyor 1. Each set of bearing supports 31 is connected to a wire mesh support roller 32. The wire mesh support rollers 32 are horizontally arranged and perpendicular to the conveying direction of the conveyor 1, and the multiple wire mesh support rollers 32 are arranged along the conveying direction of the conveyor 1. The supporting surfaces at the top of each wire mesh support roller 32 are higher than those of the conveyor 1. The conveyor 2 is equipped with a blowing device 4. The blowing device 4 includes a support frame 41 mounted on the frame of the second conveyor 2. A guide hood 42 is fixedly mounted on the support frame 41. The air outlet of the guide hood 42 faces downward and is located above the second conveyor 2. The guide hood 42 is an inverted truncated pyramid structure. A fan bracket 45 is fixedly mounted at the center of the top of the guide hood 42. Centrifugal fans 43 are symmetrically mounted on both sides of the fan bracket 45, and the inlet ends of the centrifugal fans 43 are all connected to the top of the guide hood 42. The bottom opening width of the guide hood 42 is adapted to the conveying width of the second conveyor 2. A guide plate 44 is provided on the left side of the bottom opening of the guide hood 42, and the guide plate 44 is inclined downward to the right. Conveyor 1, Conveyor 2, and Conveyor 3 are all chain conveyors. Conveyor 2 includes conveyor chains 21 symmetrically arranged on the front and rear sides of its frame. Each link of the conveyor chain 21 is provided with a support plate 23 for supporting the pad 600. The support plate 23 has an inverted U-shaped structure, and the top surface of the support plate 23 is provided with anti-slip protrusions 231. U-shaped steel 22 is horizontally arranged on the frame of Conveyor 2 at the corresponding positions of the conveyor chains 21. The conveyor chains 21 are slidably sleeved in the steel grooves of the corresponding U-shaped steel 22. Conveyor 1 and Conveyor 3 have the same structure as Conveyor 2.
[0013] In use: After the pad 600 separates from the hot-pressed slab, it enters the pad recycling system. When the pad 600 is conveyed to conveyor 1, the worker can easily lift the pad 600 with fibrous impurities onto the burning roller table 3 for burning. The worker does not need to move with the pad 600, making cleaning the pad 600 relatively easy and reducing labor intensity. After the burning operation is completed, the pad 600 is pushed downstream of conveyor 1 or onto conveyor 3 5, which then transports the pad 600 to conveyor 2. When the pad 600 passes the blowing device 4, the centrifugal fan 43 blows air into the air guide hood 42. The airflow in the air guide hood 42 is forced to tilt and blow towards the pad 600 after passing through its air outlet and air guide plate 44, thus removing the residue on the pad 600. The U-shaped steel 22 guides the movement of the conveyor chain 21 to prevent the conveyor chain 21 from running off-center. The pad 600 is stably supported by the pallet 23 provided on the conveyor chain 21. The pad 600 is conveyed stably. Moreover, the burning net conveying device has a simple structure and low modification cost.
