Abstract
The utility model discloses a frame sawing machine of a reciprocating saw with a plurality of saw blades. The utility model comprises a bracket, a motor, a feeding mechanism and a saw blade mechanism, wherein the feeding mechanism and a motor are arranged on the bracket; the saw blade mechanism is positioned above a feeding wheel of the feeding mechanism; the motor is pivoted with a main belt pulley; one end of the main belt pulley is connected with an eccentric wheel, and an eccentric spindle is arranged on the other end of the motor; the eccentric spindle is connected with a feeding and transmitting connecting rod which can swing left and right; the feeding and transmitting connecting rod is connected with a feeding transmitting shaft which can make the feeding and transmitting connecting rod rotate left and right; a unidirectional clutch is sheathed on the feeding transmission shaft; the output end of the feeding transmission shaft is connected with the feeding mechanism; one end of a lifting rod is fixedly connected to the eccentric wheel, and the other end of the lifting rod extends above a feeding wheel; the upper end of the lifting rod is fixed with the saw blade mechanism. The utility model has the advantages of high productive efficiency and long saw blade service life.
Description
Technical field
The utility model relates to a kind of sawing machine, specifically belongs to a kind of sawing machine of many saw blades reciprocating saw.
Background technology
Existing sawing machine mainly is to be made of pay-off and saw materials device, and wherein, pay-off all is by motor-driven independently with the saw materials device, by control device control feeding and saw material, during feeding, timber is continuously charging, and saw blade is after the decline sawmilling, timber still continues feeding, be subjected to certain resistance when saw blade is risen, saw blade and timber friction cause the temperature of saw blade to rise, saw blade ruptures easily, makes saw blade short service life.
The utility model content
The purpose of this utility model is to solve above-mentioned shortcoming, and the sawing machine of many saw blades reciprocating saw of a kind of production efficiency height, saw blade long service life is provided.
For achieving the above object: the sawing machine of many saw blades reciprocating saw, comprise support, motor, feed mechanism and saw blade mechanism, support is provided with feed mechanism and motor, saw blade mechanism is positioned at the drawing-inroller top of feed mechanism, described motor articulates a main pulley, one end of main pulley is connected with eccentric wheel, the other end is provided with eccentric main axis, eccentric main axis is connected with the feeding kinematic link that can swing, the feeding kinematic link is connected with and can makes the rotating feeding power transmission shaft in its left and right sides, be socketed with one-way clutch on the feeding power transmission shaft, the output of described feeding power transmission shaft connects with feed mechanism, affixed elevating lever one end on the described eccentric wheel, the elevating lever other end stretch to the drawing-inroller top, and the elevating lever upper end is fixed with saw blade mechanism.
Be connected by power transmission shaft between described main pulley and the eccentric wheel.
The two ends up and down of described feeding kinematic link have jack, and eccentric main axis and feeding power transmission shaft sleeve are respectively gone in the corresponding jack.
The beneficial effects of the utility model:
The utility model is by described driven by motor main pulley, the eccentric wheel rotation of main pulley one end, the affixed elevating lever of eccentric wheel moves up and down, and drives the feeding drive link by spindle eccentricity simultaneously and turns round synchronously, gives drawing-inroller by the one-way clutch Synchronous Transmission; When the saw blade mechanism on being fixed on elevating lever down moves, the synchronous feeding of one-way clutch transmission drawing-inroller, saw blade saw material, when motion is up moved, one-way clutch disengagement stopping feeding.Saw blade resets and does not saw material.One-way clutch realizes that the saw material carries out synchronously with feeding, when being subjected to feeding in the time of can avoiding above-mentioned saw blade to rise, and the resistance of timber, saw blade and timber friction cause the temperature of saw blade to rise, and saw blade ruptures easily.Like this, make the saw blade long service life, thereby enhance productivity.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is the structural representation of Fig. 1 other direction
Among the figure: 1 is support, and 2 is motor, and 3 is feed mechanism, and 301 is drawing-inroller, and 4 is saw blade mechanism, and 5 is main pulley, and 6 is eccentric wheel, and 7 is eccentric main axis, and 8 is kinematic link, and 9 is power transmission shaft, and 10 is one-way clutch, and 11 is elevating lever.
The specific embodiment
As Fig. 1, shown in 2, the sawing machine of many saw blades reciprocating saw, comprise support 1, motor 2, feed mechanism 3 and saw blade mechanism 4, support 1 is provided with feed mechanism 3 and motor 2, saw blade mechanism 4 is positioned at drawing-inroller 301 tops of feed mechanism 3, it is characterized in that, described motor 2 articulates a main pulley 5, one end of main pulley 5 is connected with eccentric wheel 6, the other end is provided with eccentric main axis 7, eccentric main axis 7 is connected with the feeding kinematic link 8 that can swing, and feeding kinematic link 8 is connected with and can makes the rotating feeding power transmission shaft 9 in its left and right sides, is socketed with one-way clutch 10 on the feeding power transmission shaft 9, the output of described feeding power transmission shaft 9 connects with feed mechanism 3, affixed elevating lever 11 1 ends on the described eccentric wheel 6, elevating lever 11 other ends stretch to drawing-inroller 301 tops, and elevating lever 11 upper ends are fixed with saw blade mechanism 4.
Be connected by power transmission shaft 9 between described main pulley 5 and the eccentric wheel 6.
The two ends up and down of described feeding kinematic link 8 have jack, and eccentric main axis 7 and feeding power transmission shaft 9 sleeve are respectively gone in the corresponding jack.
Operation principle: during unlatching, described motor 2 drives main pulley 5, eccentric wheel 6 rotations of main pulley 5 one ends, and eccentric wheel 6 affixed elevating levers 11 move up and down, drive feeding drive link 8 by spindle eccentricity simultaneously and turn round synchronously, give drawing-inroller 301 by one-way clutch 10 Synchronous Transmission; When the saw blade mechanism 4 on being fixed on elevating lever 11 down moves, the 301 synchronous feedings of one-way clutch 10 transmission drawing-inrollers, saw blade saw material, when motion was up moved, one-way clutch 10 disengagements stopped feeding.Saw blade resets and does not saw material.
