Background Art

When cutting, it is sometimes necessary to cut the material at an angle to obtain a suitable size. However, due to different usage conditions, the required angle is not the same, so the angle needs to be adjusted multiple times.

Traditional angle adjustment devices often require the removal of multiple bolts, measuring the angle with tools, and then tightening the bolts again to fix it. This process is cumbersome and wastes a lot of time.

Therefore, a cutting device with an easily adjustable cutting angle is proposed.

Summary of the invention

The purpose of the utility model is to provide a cutting device with an easily adjustable cutting angle, so as to solve the problems raised in the above-mentioned background technology.

To achieve the above object, the utility model provides the following technical solution: a cutting device with an easily adjustable cutting angle, comprising a top plate, a slide rail is installed below the top plate, a gear ring is slidably connected to the slide rail, and a cutting blade is installed on the inner side of the gear ring;

A driving gear is rotatably connected to the middle of the top plate, and the driving gear is meshed with a gear ring. A driving motor for controlling the rotation of the driving gear is installed on one side of the top plate.

Preferably, two electric push rods are symmetrically mounted on both sides of the top plate, and arc-shaped toothed plates are mounted on piston rods of the electric push rods.

Preferably, the arc-shaped tooth plate is meshingly connected with the outer side of the gear ring.

Preferably, a connecting column is installed above the slide rail, and the top end of the connecting column is connected to the lower surface of the top plate.

Preferably: a connecting plate is installed on the inner side of the gear ring, and a shell is installed on the connecting plate.

Preferably, a motor for driving the cutting blade to rotate is installed inside the housing.

Compared with the prior art, the beneficial effects of the utility model are: the gear ring and the cutting disc are driven to rotate by the driving motor and the driving gear, so that the angle adjustment can be completed quickly, and then the position of the gear ring and the cutting disc is fixed by the cooperation of the electric push rod and the arc-shaped tooth plate, so as to facilitate the cutting work. The adjustment process of this mechanism is simple and fast, and the work efficiency is improved.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

Example

Referring to Fig. 1-4, the utility model provides a technical solution: a cutting device with an easily adjustable cutting angle, comprising a top plate 1, the top plate 1 being mounted on a moving module of a cutting device so as to be able to adjust the position, a slide rail 4 being mounted below the top plate 1, a gear ring 8 being slidably connected to the slide rail 4, and a cutting blade 5 being mounted on the inner side of the gear ring 8;

The middle part of the top plate 1 is rotatably connected with a driving gear 3, which is meshed with a gear ring 8. A driving motor 2 for controlling the rotation of the driving gear 3 is installed on one side of the top plate 1, and the driving motor 2 is a stepping motor.

As shown in Figures 1 and 4: two electric push rods 10 are symmetrically installed on both sides of the top plate 1, and an arc-shaped toothed plate 9 is installed on the piston rod of the electric push rod 10, and the arc-shaped toothed plate 9 is meshed and connected with the outer side of the gear ring 8; through the above arrangement, the piston rod of the electric push rod 10 drives the arc-shaped toothed plate 9 to move, so that the arc-shaped toothed plate 9 is meshed and connected with the gear ring 8, completing the position restriction work of the gear ring 8 and avoiding the situation where the gear ring 8 moves at will.

As shown in FIG. 1 and FIG. 2 , a connecting column 11 is installed above the slide rail 4 , and the top end of the connecting column 11 is connected to the lower surface of the top plate 1 ; through the above arrangement, the position of the slide rail 4 can be more conveniently restricted.

As shown in Figures 1 and 3: a connecting plate 7 is installed on the inner side of the gear ring 8, a shell 6 is installed on the connecting plate 7, and a motor for driving the cutting blade 5 to rotate is installed inside the shell 6; through the above arrangement, the cutting blade 5 is driven to rotate by the motor, so that the cutting work can be carried out quickly.

Working principle: when the cutting angle needs to be adjusted, the drive motor 2 is started, and the drive motor 2 drives the drive gear 3 to rotate, thereby driving the gear ring 8 to rotate on the slide rail 4 through the drive gear 3, so that the angle of the cutting blade 5 can be adjusted. When the angle adjustment is completed, the electric push rod 10 is started, and the electric push rod 10 drives the arc-shaped tooth plate 9 to engage with the gear ring 8 to complete the work of limiting the position of the gear ring 8, and also fixes the position of the cutting blade 5, which is convenient for subsequent cutting work.

Although the embodiments of the present invention 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 invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
