A kind of positioning strip cutting machine
Technical field
The utility model relates to a kind of positioning strip cutting machine.
Background technology
Rock cotton board is a kind of basic material the most of building, along with constantly progressive and development of society, also more and more higher to the production equipment requirement of rock cotton board, therefore, the improvement project of cutting cutter correlation technique often occurs.Positioning strip cutting machine of the prior art is cut do straight reciprocating motion by the sliding part that drives air cylinder driven that cutting knife is housed usually, and the piston rod of cylinder easily weares and teares, and affects service life, need to be changed or keep in repair, and cost is higher.
The utility model content
The purpose of this utility model is to overcome the defect existed in prior art, and a kind of positioning strip cutting machine is provided, and increases the service life, and reduces production costs.
For achieving the above object, the technical solution of the utility model has been to provide a kind of positioning strip cutting machine, comprise cutting rack, be arranged at the slide rail on described cutting rack, length direction slip along slide rail is arranged at the sliding part on described slide rail, be fixedly installed on the cutting knife on described sliding part, drive the reciprocating driving mechanism of described sliding part, described driving mechanism comprises the pull bar that an end rotates and is connected with described sliding part, the drive rod that one end rotates and is connected with the other end of described pull bar, the output shaft that rotates and be connected with the other end of described drive rod, drive the drive motors of described output shaft rotation.
As preferably, described drive motors has motor shaft, between described motor shaft and described output shaft, is provided with transmission mechanism.
As preferably, described transmission mechanism is the bevel gear transmission.
As preferably, described drive motors is variable-frequency motor.
As preferably, the length direction of described pull bar parallels with the length direction of described drive rod.
As preferably, the length direction of described drive rod and the rotational axis line of described output shaft are perpendicular.
As preferably, the below of described cutting rack is provided with rollgang.
Advantage of the present utility model and beneficial effect are: by drive motors, drive output shaft rotation, output shaft drives drive rod and rotates, drive rod drives pull bar and does straight reciprocating motion, then driving sliding part slidably reciprocates, can reach the effect of continuous cutting, simple in structure, increase the service life, reduce production costs.

The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, a kind of positioning strip cutting machine, comprise cutting rack 1, be arranged at the slide rail 2 on described cutting rack 1, length direction slip along slide rail 2 is arranged at the sliding part 3 on described slide rail 2, be fixedly installed on the cutting knife on described sliding part 3, drive the reciprocating driving mechanism of described sliding part 3, described driving mechanism comprises the pull bar 4 that an end rotates and is connected with described sliding part 3, the drive rod 5 that one end rotates and is connected with the other end of described pull bar 4, the output shaft 6 that rotates and be connected with the other end of described drive rod 5, the drive motors 7 that drives described output shaft 6 to rotate.The below of described cutting rack 1 is provided with rollgang 8.
As shown in Figure 1, described drive motors 7 has motor shaft, between described motor shaft and described output shaft 6, is provided with transmission mechanism.Described transmission mechanism is the bevel gear transmission.Can be also worm and gear in addition, belt pulley etc.
As shown in Figure 1, described drive motors 7 is variable-frequency motor.
As shown in Figure 1, the length direction of described pull bar 4 parallels with the length direction of described drive rod 5.
As shown in Figure 1, the rotational axis line of the length direction of described drive rod 5 and described output shaft 6 is perpendicular.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
