Abstract:
A workpiece processing system is provided that includes a first carousel rotary conveyor associated with a first plurality of stations through which workpieces are successively rotationally conveyed, a second carousel rotary conveyor associated with a second plurality of stations through which the workpieces are successively rotationally conveyed, and an inter-carousel transport configured to selectively operate in a first mode and a second mode. In the first mode, the inter-carousel transport is operable to successively transfer the workpieces from the first carousel rotary conveyor to the second carousel rotary conveyor. In the second mode, the inter-carousel transport is operable to successively reorient the workpieces of a selected one of the first carousel rotary conveyor or the second carousel rotary conveyor by approximately 180 degrees of rotation for further successive rotational conveyance of the workpieces through the stations associated with the selected first or second carousel rotary conveyor.
Abstract:
The invention claims a flame-retardant and corrosion-resistant fiber bamboo substrate and a preparation method thereof. The preparation method comprises the following steps of: 1) cutting raw bamboo into bamboo filaments; 2) flame-retardant treatment: soaking the bamboo filaments prepared in Step 1) in aqueous solution of a flame retardant; 3) drying: drying the flame-retardant treated bamboo filaments at 55° C. to 65° C. until the absolute water content is not more than 12%; 4) carbonized pyrolysis: feeding the dried bamboo filaments into a carbonized pyrolysis kiln, to be high-temperature treated according to a pyrolysis gradient; and, 5) sequentially gumming, post-gumming drying, pressing, curing, maintaining and splitting to obtain a bamboo substrate. The bamboo substrate has high stability, no cracks on the product surface, enhanced corrosion resistance and excellent flame retardance, and may be used in various climate conditions and environments.
Abstract:
This invention relates to the woodworking industry. The method of processing of wood products across the grain in two or more planes with various cross-section shapes includes orientation, locating with subsequent clamping, feeding and processing along the mutually perpendicular generatrices. Multiple products can be processed at the same time. The products are placed in the transverse direction relative to the longitudinal axis of the product, as well as to the longitudinal axis of the processing lines, and to the longitudinal axis of the bench. The products are shifted from the processing lines so that all the auxiliary operations are performed simultaneously and automatically in each plane. The lengths of the products to be processed simultaneously shall be matched with respect to each other to satisfy the condition under which their total length shall be equal or as close as possible to the length of the standard input workpiece. For processing, the products shall be moved with respect to the fixed electric power drives. Operations of each product processing are divided into groups of operations. Each group of operations processes simultaneously the products throughout the length of the workpiece in one plane. The time of executions of all the groups of operations shall be equal, or closely comparable to each other. Each group of operations is performed in a separate zone. After completing a group of operations, the products are moved to the next zone. The zone of the previous operations shall be freed for processing the next product. Starting from the number of a group of operations for processing the products in the first plane, corresponding to the quantity of groups of operations into which the full cycle of products processing is divided, the processing of the products is performed simultaneously in all the processing planes. The procedure of simultaneous processing of product batches in all planes shall be repeated until the full completion of the product batch processing. The processing of the next product batch is performed in the same way. This improves the product processing performance. 5 figures.
Abstract:
A strip coupling tenon forming machine for cutting a plurality of strips includes a station and a movement deck located on the station, a plane cutting device and a sawteeth cutting device. The movement deck has a holding deck to hold the strips, a slide element to carry and slide and swivel the holding deck and a rotary element. The rotary element has a holding bar anchored on the station and a rotary bar to support the holding deck. The rotary bar screws into the holding bar so that while the holding deck is swiveling its elevation also is changed. Thus, end surfaces at two sides of the strips can pass through respectively a plane cutter of the cutting device and a sawteeth cutter of the sawteeth cutting device to form respectively a coupling tenon thereon that are matched in elevation.
Abstract:
Disclosed is a device having four processing modules, arranged one behind another. Consecutive modules longitudinally cut wooden poles to narrower pieces. Each module has at least two corrugated feeding cylinders, at least one cutting apart wedge disc located behind them, optionally at least one fixed separating wedge located behind the cutting apart wedge disc, at least a cylinder distributing the longitudinally cut wooden poles and at least one cylinder crushing bundles of fibres of the longitudinally cut wood. There is a support and transport line situated along the workpiece transport route in each processing module. In case of a larger number of wedge discs in a processing module, the cutting apart wedge discs are situated on two opposite sides of the feed path and separated in a 2:1 ratio on the two sides of the feed path of the workpiece being cut apart.
