Embodiment 1

[0025] Such as figure 1 , the present invention mainly is made up of log car, toothed roller type peeling machine 2, discharge chute 3, discharge belt conveyor 4 and bark belt conveyor 1 and bark hopper 6. The rack in the toothed roller peeling machine is provided with a rotating roller at an inclination angle of 2.6°. Above the higher end of the rotating roller is the feed port of the toothed roller peeling machine 2500×1500. Below the rotating roller It is a bark belt conveyor, one end of the bark belt conveyor is provided with a bark hopper; the frame at the lower end of the rotating roller is provided with a discharge chute connected to the discharge belt conveyor.

[0026] The main technological process of the present invention: the wood grab car puts the small-diameter timber into the feed port of the toothed roller peeling machine 2500 × 1500, utilizes the toothed rotating roller in the toothed roller peeling machine and the equipment arranged at an inclination of 2.6°,...

Embodiment 2

[0028] Such as figure 2 Shown, toothed roller type peeling machine mainly is made up of rotating drum 5, casing 22 and frame 23. The rotating roller is set on the rotating roller seat of the frame, and the top of the rotating roller is a tumbling area 24 for small-diameter materials; the two sides of the rotating roller are casings; there is a slag discharge gap 25 between the casing and the rotating roller ; The bottom of the rotating roller is provided with a bark belt conveyor 1.

Embodiment 3

[0030] Such as image 3 , Figure 4 As shown, the discharge door 31 on the discharge chute 3 is controlled by a hydraulic cylinder 32 .

Abstract

The invention discloses an automatic efficient peeling line for small diameter logs. The automatic efficient peeling line is characterized by mainly comprising a tooth roller peeling machine, a discharging chute, a discharging conveying belt, a log grabbing car, a chipping machine, a bark conveying belt and a bark hopper. Two principles of mechanical peeling and frictional peeling are organically combined, the purposes of saving energy and high efficiency are achieved, and the requirements for high peeling production capacity and low log damages of the small diameter logs are met. According to the automatic efficient peeling line for the small diameter logs, the process is simple, the equipment operation is safe and stable, the energy consumption is low, and the investment cost is low.

Description

technical field [0001] The invention relates to a high-efficiency automatic peeling line for small-diameter timber, which belongs to the field of pulp and papermaking and is suitable for high-efficiency automatic peeling of small-diameter timber. Background technique [0002] The main raw material for pulping in the pulp and paper industry is wood chips. The wood chips required for pulping are mainly produced by log chips, and peeling is one of the key processes to determine the quality of wood chips after log chipping. The large-diameter log peeling technology has matured, and the production capacity, wood chip quality, and wood damage have all reached relevant standards. At present, the peeling of small-diameter timber (fresh wood with a diameter below 100mm) generally adopts imported or domestic automatic peeling lines (logging machine--peeling drum--chain plate machine--chipper) and semi-automatic peeling lines (manual feeding- - peeling drum--manual transfer--chipper),...
