Bamboo arrow rod straightening machine

Abstract

The invention discloses a bamboo arrow rod straightening machine. The bamboo arrow rod straightening machine comprises a feeding opening, a heating softening device, a fiber kneading softening device, a cooling shaping device, a discharge opening and a transmission motor, wherein the heating softening device comprises a plurality of transmission wheels arrayed at intervals and heating tubes; the transmission wheels are respectively positioned at two ends of each heating tube; the fiber kneading softening device comprises a rotating plate, an eccentric hole and a conical nozzle arranged at the front end of the eccentric hole; the cooling shaping device comprises a plurality of press fitting shapers, a plurality of transition wheels and an air cooling device; the press fitting shapers and the transmission wheels are arrayed at intervals; and the transmission motor is in transmission connection with the transmission wheels, the rotating plate and the transition wheels. By the structure, a bamboo arrow rod extends in a feeding opening, is heated and softened, kneaded and softened through fibers, cooled and shaped, and then is discharged through the discharge opening; straightening of the bamboo arrow rod is finished at one step, continuous operation can be realized, and production effect and production quality are greatly improved; and meanwhile, the straightness of the made bamboo arrow rod is the same as that of a white wood rod, and further, the bamboo arrow rod has quite high hardness and toughness.

Description

technical field [0001] The invention relates to the field of traditional bamboo arrows, in particular to a straightening machine for bamboo arrow shafts. Background technique [0002] The current traditional arrow making process is as follows: [0003] Selection of materials: wood (cedar, six wood, birch, poplar, etc.), bamboo (arrow bamboo, water bamboo, bitter tea bamboo), feathers (wing feathers of eagles, geese, turkeys, geese, pheasants, etc.), arrowheads (iron, copper, bone, horn), glue (traditional swim bladder glue, modern glue), reinforcing thread (tendon, nylon thread), lacquer or tung oil. [0004] 1. Selection of tools: saw (truncated arrow shaft), file (board file, garden file, assorted file), knife (repair rod, split feather), sandpaper (coarse sandpaper, fine sandpaper), feather clip, charcoal stove (gas , electric heater), scissors (for cutting feathers), tools for burning feathers (feather burning device, wallpaper knife, electric soldering iron, etc.) ...

AI Technical Summary

Problems solved by technology

[0012] Therefore, the production of traditional arrows is complicated and time-consuming. Especially in the straightening process of bamboo arrow shafts, the main method is to use manual methods: first heat the bent parts with fire, and then hold the arrow terminal in one hand and the arrow shaft in the other. Embed the heated bent part in the groove of the arrow terminal, and then clamp it firmly with both hands, repeating it several times to make the arrow shaft straighter

[0013] In the industrial production of bamboo arrow shafts, it takes more than one year to train a mature straightening worker to ensure the accuracy of visual inspection. Uncertain factors often require repeated alignment, which greatly affects industrial production efficiency and production quality
