Abstract

The utility model relates to a provided sawing machine with auto-feeding. In the provided sawing machine with auto-feeding, an interval type of transmission form and a rolling type material feeding device are used; 30 saw blades can be abreast placed in a saw frame. Under the same conditions of power consumption and time, the provided sawing machine with auto-feeding has yield which is one time more than the yield of a disk saw, when processing 30 sheets simultaneously; therefore, work efficiency is improved. Due to the interval type of material feeding and work doing, the thickness of each of the saw blades is 2 to 3 times thinner than the thick of the disk saw; therefore, large quantity of timber can be saved. For example, when a sheet whose thickness is 15 mm is processed, one sheet can be saved by four kerfs. The utility model has reasonable design and simple structure.

Description

Arranged sawing machine with auto-feeding

The utility model belongs to wood processing machinery, is specifically to use the device that timber is processed into sheet material.

The used machinery of converted timber is two kinds substantially at present, and a kind of is circular saw machine, and another kind is a band saw, and machining sheet is most popular to be circular saw machine.Circular saw machine has following shortcoming: the one, need 2 operating personnel during work at least, one people advances timber at feed end, another people draws at discharge end, therefore when discharging begins to draw and charging is the most last when pushing away, operating personnel had certain danger, do not note slightly sawing and hinder finger, and labour intensity is big, work under bad environment.The 2nd, saw kerf is big, is 4 millimeters as the saw kerf thickness of the garden saw blade of 350 mm dias, and the saw kerf thickness of the garden saw blade of 500 mm dias is 5 millimeters, and therefore, waste timber is serious.The 3rd, not steady by the manpower feeding because circular saw machine does not have the feeding fixture, therefore the timber size error of processing is big.Band saw can not be processed and be shorter than 1.5 meters long timber except that having some deficiency of circular saw machine, no matter and circular saw machine or band saw has only a slice saw blade or saw blade, can only the processing of a slice a slice during work, efficient is low.

The utility model is designed automatic feed at above-mentioned shortcoming exactly, and high efficiency can be saved the wood processing machinery of a large amount of timber.

Fig. 1 is the utility model right side primary structure schematic diagram (left side and right side same section omit).

As shown in Figure 1, the utility model is to connect two connecting rods (2) by two cranks (1), connecting rod connects saw frame (3) again, saw frame is bearing on the slider block by slide bar, slider block is fixed on the mainframe, saw frame is respectively equipped with up and down the box that saw blade is installed and the helical compression spring that is used for connecing tight saw blade, can lay at most 30 saw blades (4) according to the processing needs in the saw frame, the spacing of saw blade can be regulated by gullet plate and screw rod, adjustable range is the 8-500 millimeter, both sides, saw frame lower end connect respectively two waling stripes (5), be equipped with ratchet (6) on the connecting rod, ratchet will be buckled on the tooth of ratchet (7), in the ratchet the inside sprocket wheel is housed, with chain (8) two sprocket wheels (10) that the sprocket wheel in the sprocket wheel and ratchet is outer, (11), and 3 feed spools (9) and a discharging axle (12) link up. Above feed spool, be equipped with four groups and the equally spaced binder axle of feed spool (13), utilize spring (14) to compress charging timber, binder axle upper end is equipped with lifting handle (15), utilize spring that the binder axle is risen, put well and fall again the binder axle behind the timber and feed spool all is installed on the cradle, two lifting sieve bolts also are housed on the cradle, can adjust according to the thickness of timber the pressure of binder axle.

The actuating unit of gang saw mill is made up of motor, flange terminal pad, clutch terminal pad and speed-changing gear box, two cranks of gang saw mill are connected the output of speed-changing gear box, during gang saw mill work, earlier with the timber of required processing and be emitted on the feed spool, adjust the spacing of saw blade in the saw frame and strain saw blade according to the requirement of processing dimension.After the energising start, actuating unit drives two crank rotations of gang saw mill, crank drives saw frame by two connecting rods and does motion up and down, saw frame drives two waling stripes, ratchet on the waling stripe is buckled in and drives the ratchet rotation on the ratchet tooth, saw frame up and down once, ratchet on the connecting rod drives ratchet and rotates a tooth, ratchet rotates the sprocket rotation that drives the ratchet the inside, and this sprocket wheel is passed to the feed spool rotation with power by chain, and processed timber is moved ahead, when saw frame is descending, feeding begins simultaneously with acting, and when saw frame ran to lower dead center, acting stopped simultaneously with feeding, ratchet when saw frame is up on the waling stripe rises, break away from the ratchet tooth, ratchet does not change, the yet not feeding of therefore promptly not doing work.Because this saw is the batch (-type) acting, each inlet amount and acting amount are less, and therefore, the thickness of saw blade can be very thin, and generally can adopt saw kerf thickness is the saw blade of 1-1.5 millimeter, so just can save a large amount of timber.If lay 30 saw blades in the saw frame, can process 30 blocks of sheet materials simultaneously, improved operating efficiency greatly.

This utility model is reasonable in design, and is simple in structure, compares with circular saw machine and can save timber 20-50% owing to adopted batch (-type) transmission mechanism, saw blade can be thinned to the 1-1.5 millimeter, as process the sheet material of 15 millimeters thick, and 4 saw kerfs just can save a plate.In addition also have following advantage: the one, the automaticity height, labour intensity is low, need not be manually direct control at the scene, the 2nd, the production efficiency height is compared with circular saw machine, under the consumed power condition identical with the artificial time, output can improve 50%.
