[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0024] According to an embodiment of the present utility model, a cutting structure is provided. Please refer to Figures 1 to 3 , including: a frame 1, the frame 1 includes a first bracket 11 and a second bracket 12; a cutting assembly 2, the cutting assembly 2 is movably arranged on the first bracket 11; a support assembly 3, one end of the support assembly 3 is rotatably connected to the second bracket 12 relatively, the other end of the support assembly 3 is rotatably connected to the cutting assembly 2 relatively, the support assembly 3 includes a support rod 31 and a driving component 32, the support rod 31 is telescopically arranged, the driving component 32 is used to drive the support rod 31 to expand and contract, and the support rod 31 is used to drive the cutting assembly 2 to move along the cutting direction.
[0025] With the above settings, when the cutting machine cuts the rubber material, the driving component 32 in the support assembly 3 drives the support rod 31 to extend, and the support rod 31 drives the cutting assembly 2 to move along the cutting direction. In this way, when the rubber material adheres to the cutting assembly 2, since the support rod 31 restricts the movement of the cutting assembly 2 in other directions, the cutting assembly 2 always moves in the cutting direction and will not be offset due to the drive of the rubber material, solving the technical problem that there is a gap between the upper knife and the lower knife on the cutting machine when cutting the rubber material in the related art.
[0026] Preferably, the driving component 32 is a cylinder or a hydraulic cylinder.
[0027] Specifically, the cutting direction is the direction in which the cutting assembly 2 moves to align with the lower knife.
[0028] Preferably, the frame 1 is welded and processed from high-quality steel sections, and one end of the first bracket 11 is connected to the second bracket 12.
[0029] In the cutting structure of this embodiment, referring to Figure 1 , one end of the support rod 31 is connected to the driving component 32, and the other end of the support rod 31 is rotatably connected to the cutting component 2. There is an angle between the extending direction of the support rod 31 and the cutting direction. In this way, due to the angle between the support rod 31 and the cutting direction, when the support rod 31 extends, the support rod 31 has a downward thrust on the cutting component 2, pushing the cutting component 2 to move in the direction of the lower knife 4. At the same time, there is also a force that pushes the cutting component 2 in the direction of approaching the first bracket 11, so that the cutting component 2 will not shift in the horizontal direction and can always be aligned with the lower knife, solving the technical problem that there is a gap between the upper knife and the lower knife of the cutting machine when cutting rubber materials in the related art.
[0030] Specifically, the angle between the support component 3 and the cutting direction is set according to the strength of the material to be cut. When the upper knife descends for cutting, the support component 3 provides two kinds of forces. One is the downward cutting force, and the other is the radial thrust force that makes the upper and lower knives fit tightly. At the same time, the greater the resistance of the cutting material, the greater the radial thrust force. On the contrary, the smaller the cutting resistance, the smaller the radial thrust force.
[0031] In the cutting structure of this embodiment, referring to Figures 1 to 2 , the cutting structure further includes a lower knife 4. The lower knife 4 is arranged on the first bracket 11 and is arranged corresponding to the cutting component 2. When the cutting component 2 moves to the corresponding position, the cutting component 2 abuts against the lower knife 4 to cut the object to be cut. In this way, when the driving component 32 drives the support rod 31 to drive the cutting component 2 to move downward until it abuts against the lower knife, the upper knife and the lower knife are aligned, and the two cut the film by extrusion to complete the cutting.
[0032] In the cutting structure of this embodiment, referring to Figure 3 , a fixing component 112 is arranged on the first bracket 11. An installation groove 1121 is arranged on the side of the fixing component 112 close to the cutting component 2. The installation groove 1121 is used for installing the lower knife 4. Specifically, a plurality of installation holes are arranged on the side surface of the installation groove 1121, and there is a threaded structure in the installation holes. The lower knife 4 is also provided with holes at the corresponding positions of the installation holes. The lower knife 4 is fixed in the installation groove 1121 by meshing the bolts with the threads in the installation holes, so that the lower knife 4 will not move with the transfer of the rubber material.
[0033] Preferably, the distance between the lower knife 4 and the side surface of the installation groove 1121 can be adjusted by adjusting the bolts.
[0034] In the cutting structure of this embodiment, referring to Figures 1 to 2, the cutting component 2 includes: an upper knife 21, which is arranged corresponding to the lower knife 4; a connecting plate body 24, and the upper knife 21 is fixed on one side of the connecting plate body close to the lower knife 4; a first connecting component 22, which is arranged on one side of the connecting plate body 24 close to the first bracket 11, and the first connecting component 22 is movably connected to the first bracket 11; a second connecting component 23, which is arranged on the side of the connecting plate body 24 away from the first bracket 11, and the second connecting component 23 is rotatably connected to the support rod 31. In this way, the connecting plate body 24 connects the upper knife and the first bracket 11, and the second cutting component 23 connects the support rod 31 and the connecting plate body 24. When the support rod 31 extends, it can drive the connecting plate body 24 to move along the cutting direction.
[0035] In the cutting structure of this embodiment, refer to Figure 3 , on one side of the first connecting component 22 close to the first bracket 11, there is a chute; on one side of the first bracket 11 close to the cutting component 2, a slide rail 111 is arranged, and the extending direction of the slide rail 111 is parallel to the extending direction of the first bracket 11, and the slide rail 111 is movably arranged in the chute. In this way, the first connecting component 22 is sleeved outside the slide rail and moves along the extending direction of the slide rail. When the support rod 31 gives a downward moving force to the cutting component 2, the first connecting component 22 moves downward along the slide rail.
[0036] In the cutting structure of this embodiment, refer to Figure 1 , there are at least two first connecting components 22, and at least two first connecting components 22 are arranged on one side of the connecting plate body 24 close to the first bracket 11 at intervals, and at least two first connecting components 22 are fixedly connected to the connecting plate body 24; there are at least two slide rails 111, and at least two slide rails 111 are arranged on the first bracket 11 at intervals, and at least two slide rails 111 are arranged corresponding to the first connecting components 22 one by one. In this way, at least two first connecting components 22 are distributed on both sides of the connecting plate body 24, making the connecting plate body 24 more stable during sliding, reducing the deformation of the connecting plate body caused by the adhesion of the object to be cut, and enabling the upper knife to always be aligned with the lower knife, solving the technical problem that there is a gap between the upper knife and the lower knife of the cutting machine when cutting rubber materials in the related art.
[0037] In the cutting structure of this embodiment, refer to Figure 2, there are at least two second connecting members 23, and the two second connecting members 23 are arranged at intervals on the side of the connecting plate body 24 away from the first bracket 11; there are at least two support rods 31, and at least two support rods 31 are arranged corresponding to the second connecting members 23 one by one. In this way, at least two second connecting members 23 correspond to at least two support rods 31, and the thrust of the multiple support rods 31 on the connecting plate body 24 in the horizontal direction is greater and the force on the connecting plate body 24 is more uniform, reducing the deformation of the connecting plate body caused by the adhesion of the object to be cut, and enabling the upper knife to always be aligned with the lower knife, solving the technical problem that there is a gap between the upper knife and the lower knife of the cutting machine when cutting rubber materials in the related art.
[0038] In the cutting structure of this embodiment, refer to Figure 2 , the shortest distance between the upper knife 21 and the lower knife 4 gradually changes in the horizontal direction. In this way, point contact is achieved between the upper knife 21 and the lower knife 4, and different angles can be designed to adapt to materials to be cut with different hardnesses and strengths.
[0039] Preferably, the greater the hardness and strength of the material, the greater the angle.
[0040] This embodiment provides a cutting machine, and the cutting machine includes the above-mentioned cutting structure.
[0041] With the above settings, the movement direction of the cutting assembly 2 is restricted by the support structure 3, so that the cutting assembly 2 can only move along the cutting direction and will not shift due to the adhesion of the material to be cut, thereby enabling the upper knife and the lower knife to always be aligned, solving the technical problem that there is a gap between the upper knife and the lower knife of the cutting machine when cutting rubber materials in the related art.
