AI Technical Summary
When trimming the end edges of the rectangular air filter element, the existing edge cutting machines cannot achieve root-to-root cutting due to the deviation of about 0.5mm in the width of the filter element, which requires manual trimming and low efficiency.
A root-length cutting machine is designed, including a frame, corresponding edge-length cutting mechanism and material pushing mechanism. By coordinating the edge-length cutting head and the movable blade head with the edge-length expansion cylinder, the front and rear sides of the filter element are realized.
The filter element is fully cut in the roots, with simple structure and convenient operation, avoiding the need for manual trimming and improving production efficiency.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filter element production, in particular to a straight edge shearing machine. Background Art
[0002] In the production process of the rectangular air filter element, when the side edges are pasted first and then the end edges are pasted, there are excess edges at both ends of each edge strip that need to be trimmed to be flush with the side edges. If a trimming machine is used to trim the side edges, the scissors are fixed after the spacing is adjusted. Since the width of the filter element generally has a deviation of about plus or minus 0.5mm, when trimming the filter element with a smaller width, excess edges will be generated and it is impossible to trim it flush with the root. Therefore, the current process for trimming the excess edges of the end edges still uses manual labor to trim them with scissors to align with the side edges.
[0003] Therefore, in view of the shortcomings of the prior art, it is necessary to design a root edge shearing machine to solve the above problems. Utility Model Content

[0006] The preferred technical solution is: the first trimming mechanism, the second trimming mechanism, the third trimming mechanism and the fourth trimming mechanism have the same structure and are all composed of a fixed cutter head, a movable cutter head and a trimming telescopic cylinder, the fixed cutter head and the trimming telescopic cylinder are fixed on the frame, the movable cutter head is arranged on the outside of the fixed cutter head along the left and right direction, and the movable cutter head is driven by the trimming telescopic cylinder to approach or move away from the fixed cutter head along the left and right direction.

[0008] The preferred technical solution is: the first pushing mechanism and the second pushing mechanism have the same structure and are both composed of a pushing cylinder and a pushing rod. The pushing cylinder is fixed on the frame and is used to drive the pushing rod to push the filter element in the front-rear direction.
[0009] The preferred technical solution is: the first pushing mechanism has two pushing rods, which are defined as first pushing rods, and the distance between the two first pushing rods is smaller than the distance between the two edges to be trimmed on the front side of the filter element; the second pushing mechanism has two pushing rods, which are defined as second pushing rods, and the distance between the two second pushing rods is smaller than the distance between the two edges to be trimmed on the rear side of the filter element.

Similarly, the filter element can also be pushed to the front side by the second material pushing mechanism, so that the two edges to be trimmed on the front side of the filter element are located outside the fixed blade heads of the first and second edge trimming mechanisms, and then the edge trimming telescopic cylinders and movable blade heads in the first and second edge trimming mechanisms cooperate to remove the two edges to be trimmed on the front side of the filter element by flush cutting.

[0021] like Figure 1 As shown, in an exemplary embodiment of the present invention, the first pushing mechanism and the second pushing mechanism have the same structure and are both composed of a pushing cylinder 5 and a pushing rod. The pushing cylinder 5 is fixed on the frame and is used to drive the pushing rod to push the filter element 1 along the front and rear directions.
[0022] like Figure 1 As shown, in an exemplary embodiment of the present utility model, the first pushing mechanism has two pushing rods, which are defined as first pushing rods 61, and the distance between the two first pushing rods 61 is smaller than the distance between the two edges to be trimmed on the front side of the filter element 1; the second pushing mechanism has two pushing rods, which are defined as second pushing rods 62, and the distance between the two second pushing rods 62 is smaller than the distance between the two edges to be trimmed on the rear side of the filter element 1. The above structure is used to achieve stable front and rear pushing of the filter element 1 to avoid deviation during the pushing process.
[0023] Therefore, the utility model has the following advantages:
[0024] The utility model provides a flush edge trimming machine. When in use, the filter element is pushed to the rear side by the first material pushing mechanism, so that the two edges to be trimmed on the rear side of the filter element are located outside the fixed blade heads of the third and fourth edge trimming mechanisms, and then the edge trimming telescopic cylinders and movable blade heads in the third and fourth edge trimming mechanisms cooperate to remove the two edges to be trimmed on the rear side of the filter element by flush cutting. Similarly, the filter element can also be pushed to the front side by the second material pushing mechanism, so that the two edges to be trimmed on the front side of the filter element are located outside the fixed blade heads of the first and second edge trimming mechanisms, and then the edge trimming telescopic cylinders and movable blade heads in the first and second edge trimming mechanisms cooperate to remove the two edges to be trimmed on the front side of the filter element by flush cutting.
