[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0018] See also Figure 1-2 A sawing device for plastic products includes a device frame 1, a rotating shaft 2 is fixedly penetrated on the inner side of the device frame 1, a sawing frame 3 is rotatably connected to the outer surface of the rotating shaft 2, a plurality of groups of limit rings 4 are arranged on the outer surface of the rotating shaft 2, a sawing mechanism is arranged on the top of the sawing frame 3, and a rotation angle mechanism for adjusting the sawing angle of the cutting knife 7 is arranged on the outer surface of the device frame 1.
[0019] Through the above technical solution, when the device is in use, the cutting blade 7 in the sawing mechanism can stably saw the plastic product, and at the same time, the incision can be chamfered or the burr can be rounded under the action of the angle rotation mechanism.
[0020] Specifically, the sawing mechanism includes a motor 5 fixedly mounted on the top of the sawing frame 3 , and a driving shaft 6 is fixedly connected to the output end of the motor 5 .
[0021] Through the above technical solution, turning on the motor 5 can drive the driving shaft 6 to rotate, and finally the cutting knife 7 is linked to rotate at a high speed to stably saw the plastic products.
[0022] Specifically, a cutting knife 7 is provided at one end of the driving shaft 6 away from the motor 5 , and a material guide cover 8 is fixedly installed on the top of the sawing frame 3 .
[0023] Through the above technical solution, the material guide cover 8 can guide the waste chips generated during the sawing process of the cutting knife 7 to reduce the random splashing of the waste chips.
[0024] Specifically, the rotation angle mechanism includes damping shafts 9 respectively arranged on both sides of the device frame 1 , and the outer surfaces of the two groups of damping shafts 9 are rotatably connected to the swing bars 10 .
[0025] Through the above technical solution, the damping characteristics of the damping shaft 9 allow it to remain relatively stable after being rotated to a corresponding angle if there is no external force.
[0026] Specifically, a guide bar hole 11 is opened on the surface of the swing bar 10 , and positioning shafts 12 are fixedly connected to both sides of the sawing frame 3 , and the outer surface of the positioning shaft 12 is slidably connected to the inner wall of the guide bar hole 11 .
[0027] Through the above technical solution, the positioning shaft 12 can drive the swing bar 10 to swing synchronously through the guide bar hole 11 during the swinging process.
[0028] Specifically, a butterfly nut 13 is threadedly sleeved on the outer surface of the positioning shaft 12 .
[0029] Through the above technical solution, when the butterfly nut 13 is rotated along the positioning shaft 12 to tightly abut against the swing bar 10, the entire sawing frame 3 together with the sawing mechanism on the top can maintain stability after the angle is adjusted.
[0030] Working principle: When the device is in use, the sawing mechanism can saw the plastic products, that is, it only needs to start the motor 5 to drive the driving shaft 6 to rotate, thereby linking the cutting knife 7 to rotate at high speed, and the cutting knife 7 can stably saw the plastic products. A certain amount of waste chips will be generated during the sawing process. The guide cover 8 can guide and block the waste chips to a certain extent, reduce the directionless splashing of the waste chips, and optimize the working environment. During the sawing process, the plastic products are prone to burrs and other uneven conditions at the incision. At this time, the burrs can be smoothed by adjusting the angle of the cutting knife 7. That is, at this time, it is only necessary to rotate the sawing frame 3 along the rotating shaft 2. The sawing frame 3 will drive the positioning shaft 12 to rotate simultaneously during the rotation process. During this process, the positioning shaft 12 will slide along the inner wall of the guide bar hole 11 opened on the surface of the swing bar 10, and drive the position of the swing bar 10 through the guide bar hole 11, so that the swing bar 10 rotates along the damping shaft 9. After the sawing frame 3 rotates to a suitable position (that is, the cutting knife 7 is adjusted to a suitable angle), the butterfly nut 13 is screwed along the positioning shaft 12. The butterfly nut 13 will gradually move toward the swing bar 10 while rotating along the positioning shaft 12. When the butterfly nut 13 moves to a position tightly against the swing bar 10, the sawing frame 3 is stabilized. At this time, the incision can be chamfered by the high-speed rotating cutting knife 7, and the uneven or burred parts of the incision can be smoothed and flattened, which effectively reduces safety hazards.
[0031] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
