Description

Technical Field

[0001] The utility model relates to a limiting device for a material cutting machine. Background Art

[0002] At present, the rear limit block of the paper cutter in the industry is perpendicular to the extension direction of the paper, so as to block and limit the rear end of the paper. When working, the paper cutter can cut rectangles or squares of equal width. When cutting trapezoids of unequal widths, the user needs to manually place the paper at a certain angle before cutting. However, in actual implementation, manual placement cannot guarantee that the paper is placed at the same angle every time, which easily leads to inconsistent cutting angles and insufficient cutting accuracy. It is necessary to solve this problem. Utility Model Content

[0003] The utility model overcomes the shortcomings of the above-mentioned technology and provides a limiting device for a material cutting machine.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A limiting device for a cutting machine is used to block and limit the rear side of a piece to be cut, comprising a body 1, on which is mounted a first movable seat 2 capable of moving straight forward and backward, the first movable seat 2 being connected to a second movable seat 4 capable of moving straight forward and backward via a first driving mechanism 3, the first movable seat 2 being movably connected to a blocking and limiting member 6 capable of swinging around a vertical axis 5 for blocking and limiting the rear side of the piece to be cut, a transmission rod 7 is hinged between the second movable seat 4 and the blocking and limiting member 6 for driving the blocking and limiting member 6 to swing back and forth around the vertical axis 5 when the second movable seat 4 moves straight forward and backward, the front end of the blocking and limiting member 6 is recessed with a plurality of avoidance grooves 61 distributed left and right and connected up and down respectively, and a blocking and limiting wall body 62 for blocking and limiting the rear side of the piece to be cut is provided between adjacent avoidance grooves 61.

[0006] Preferably, the first driving mechanism 3 adopts a motor screw sleeve assembly.

[0007] Preferably, an extension piece 21 extending forward is provided at one of the left and right ends of the first movable seat 2, the first end of the blocking and limiting member 6 is rotatably connected to the extension piece 21 through the vertical axis 5, and one end of the transmission rod 7 is hingedly connected to the middle part of the blocking and limiting member 6.

[0008] Preferably, a cutter is installed on the machine body 1 and is located above and in front of the blocking and limiting member 6 for cutting the material to be cut below.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. The structure of this case is simple and easy to implement. The setting that the first movable seat on the machine body can move linearly back and forth facilitates adjusting the front and back positions of the blocking and limiting member as needed to block and limit the rear side of the workpiece to be cut. The settings of the first driving mechanism, the second movable seat, and the transmission rod on the first movable seat facilitate adjusting the angle of the blocking and limiting member as needed. After adjusting the front and back positions and the angle of the blocking and limiting member, aligning the straight edge at the rear end of the workpiece to be cut with the blocking and limiting member can place the workpiece to be cut at the required angle, which is beneficial for subsequent cutting of workpieces at the same angle each time, and has good practicability. Additionally, the setting of several avoidance grooves that are distributed left and right at the front end of the blocking and limiting member and are respectively communicated up and down, on the one hand, facilitates reducing its weight in the case of a relatively large size of the blocking and limiting member, and on the other hand, facilitates avoiding a certain component in a certain situation, enabling the component to contact the workpiece to be cut in the area of the avoidance groove from top to bottom through the avoidance groove.

[0012] The features of the present utility model and other related features are further described in detail through the following embodiments for the convenience of those skilled in the same industry to understand:

[0013] As Figure 1 shown, a limiting device for a cutting machine is used to block and limit the rear side of the workpiece to be cut. It includes a machine body 1, on which a first movable seat 2 that can move linearly back and forth is installed. A second movable seat 4 that can move linearly back and forth is drivingly connected to the first movable seat 2 through a first driving mechanism 3. A blocking and limiting member 6 that can swing around a vertical axis 5 to block and limit the rear side of the workpiece to be cut is movably connected to the first movable seat 2. A transmission rod 7 that facilitates the second movable seat 4 to drive the blocking and limiting member 6 to swing back and forth around the vertical axis 5 when the second movable seat 4 moves linearly back and forth is hinged between the second movable seat 4 and the blocking and limiting member 6. A plurality of avoidance grooves 61 that are distributed left and right and are respectively communicated up and down are recessed at the front end of the blocking and limiting member 6. A blocking and limiting wall body 62 for blocking and limiting the rear side of the workpiece to be cut is provided between adjacent avoidance grooves 61.

[0014] As described above, the structure of this case is simple and easy to implement. The first movable seat 2 on the machine body 1 is arranged to be able to move linearly back and forth, which is convenient for adjusting the front and back positions of the blocking and limiting member 6 as needed to block and limit the rear side of the workpiece to be cut. The settings of the first driving mechanism 3, the second movable seat 4, and the transmission rod 7 on the first movable seat 2 are convenient for adjusting the angle of the blocking and limiting member 6 as needed.

The first end of the blocking and limiting member 6 is rotatably connected to the extension member 21 through the vertical shaft 5. One end of the transmission rod 7 is hinged to the middle of the blocking and limiting member 6. Its implementation is convenient, which is convenient for driving the second end of the blocking and limiting member 6 to swing forward through the transmission rod 7 when the second movable seat 4 moves forward relative to the first movable seat 2, and is convenient for driving the second end of the blocking and limiting member 6 to swing backward through the transmission rod 7 when the second movable seat 4 moves backward relative to the first movable seat 2.
