Description
Technical Field
The utility model relates to a panel conveying mechanism for press belongs to panel processing technology field.
Background
The wood board is a common material in the building industry, furniture manufacturing and decoration, and the processing of the board involves a plurality of procedures as required: log cutting, splicing, glue spraying, pressing, reprocessing and the like. The log pressing process generally includes stacking a plurality of boards layer by layer, spraying glue on each layer of board in the stacking process, conveying the boards into a press for pressing, and conveying the boards to the next processing device after the boards are pressed.
The laminated plates need to be conveyed into a press for pressing, and the conveying of the multilayer plates is generally realized through a plurality of parallel chains, however, the size of the single-layer plates adopted by log pressing is large, the weight of the plates after the multilayer plates are laminated and pressed is very large, the plates need to be directly pressed on a conveying chain after being conveyed into the press, and the weight of the plates acting on the chain and the pressing pressure are very large, so that the plates cannot be directly placed on the chain for conveying. In order to reduce the gravity and the pressing force borne by the chain, generally, the press is provided with bearing plates at intervals, the bearing plates are fixedly arranged on the press, the chain is arranged in a gap of the bearing plates, in order to further reduce the acting force of the pressing force on the chain, the chain is also provided with a material supporting plate, the length of the material supporting plate is matched with the width of a working face of the press, the width of the material supporting plate is matched with the integral multiple of the length of a chain plate of the chain, and the material supporting plate is fixed on the chain and synchronously runs with the chain. Because the retainer plate is arranged on the chain, in order to ensure that the rotation of the chain is not influenced by the retainer plate, the chain wheel of the conveying chain cannot be circular and can only be polygonal, the height of the highest point of the conveying chain can be changed in the rotation process of the chain wheel, if the plate is pressed by the press at the moment and part of the retainer plate does not enter the press, one side of the retainer plate is pressed by the press, so that the retainer plate is deformed, bent or even broken. Therefore, one side of the material supporting plate is generally fixed on the chain, the other side of the material supporting plate is a free end, the chain can smoothly rotate when the material supporting plate rotates to the position of the chain wheel, and the material supporting plate is not easily bent by the pressing machine when part of the material supporting plate is pressed by the pressing machine. However, since only one side of the retainer plate is fixed, and the other side of the retainer plate is not fixedly connected, when the retainer plate rotates to the position below the conveying chain, the free end of the retainer plate can bend and hang under the action of gravity, and if the retainer plate is used for a long time, the retainer plate can deform and warp, and the plates can be dislocated in the plate conveying process, so that the stress is not uniform in the pressing process, and the pressing effect is poor; in addition, if the height of the conveyor chain is low, the retainer plate may touch the ground while hanging down and move against the ground while the retainer plate is caught during rotation of the conveyor chain, causing abrasion of the retainer plate.
In addition, as the load on the chain is large, the chain is influenced by the long-time tensile force and fatigue strength, and the pitch of the chain plate is gradually elongated; the distance between the sprocket teeth of the sprocket wheel and the circle center of the sprocket wheel is fixed, and the sprocket teeth are matched with the chain plate shaft rolling sleeves of the chain, when the sprocket wheel rotates to drive the chain, the bottom of each sprocket tooth contacting with the chain is uniformly matched with the chain plate shaft rolling sleeves, if the chain plate pitch elongation of the chain is equal to the increase of the chain perimeter surrounding the gear, the chain is not consistent with the original circumference of the tooth form at the bottom of the sprocket wheel, and when the gear drives the chain, the chain cannot be uniformly stressed and conveyed unstably; can lead to chain and sprocket not good coincide when serious, the tensioning force is not enough and the circumstances such as appear skidding, conveying speed inconsistent between a plurality of chains, makes the conveying efficiency of chain reduce, carry unstablely, carry the effect not good etc.. Although the tensioning of chain can be adjusted through the distance between the central pivot of adjusting conveying chain both ends sprocket, the position of adjustment sprocket pivot can only be with the chain tensioning between the sprocket, can not solve the not good situation of sprocket and chain coincide, can only change sprocket, chain when serious, the adjustment is changed sprocket, chain and need be shut down equipment, dismantle sprocket, chain, reassembly, sprocket weight is very big, the process of changing is very troublesome, and is inefficient, with high costs.
