Description

Technical Field

[0001] The utility model belongs to the technical field of filter production, in particular to a cutting device for processing a filter center tube. Background Art

[0002] The center tube in the filter is the main component inside the filter. The raw material of the plate is intermittently punched, notched, and cut into sheets. The sheets are then curled and rounded into a columnar shape by filter processing equipment, and then transported out at a fixed length. After being transported to the set length, it is cut by a cutting device to make it the center tube of the filter.

[0003] Since the filter tube wall is relatively thin, the pipe may be subjected to greater pressure when the cutter is pressed down during the cutting process, causing the pipe to be squeezed and deformed, affecting the subsequent processing efficiency. Therefore, we have designed a cutting device for processing the filter center tube, which supports the pipe internally before cutting the pipe to avoid deformation caused by force and squeezing at the cutting position.

[0009] Preferably, four corners of the cross plate are provided with sliding grooves, and the I-shaped sliding block is slidably connected to the inner cavity of the sliding groove.

[0010] The beneficial effects of the utility model are:

[0011] The utility model places the pipeline body in the inner cavity of the pipeline support for transportation until the pipeline is against the retaining frame, and then the cylinder moves the connecting frame until the cross plate is against the end of the pipeline. At this time, the four expansion arc plates all enter the inner cavity of the pipeline body, and then the motor drives the threaded rod to rotate, causing the threaded sleeve to move to the right.

The right end of the threaded rod 73 is rotatably connected to the cross plate 71. The surface of the threaded rod 73 is threadedly connected to a threaded sleeve 74. The four surfaces of the threaded sleeve 74 are rotatably connected to an inclined rod 77 through a rotating shaft. One end of the inclined rod 77 is rotatably connected to an I-shaped slider 76 slidably connected to the cross plate 71 through a rotating shaft. The four corners of the cross plate 71 are provided with a slide groove 75. The I-shaped slider 76 is slidably connected to the inner cavity of the slide groove 75. One side of the I-shaped slider 76 is fixedly connected to an expansion arc plate 78. The expansion arc plate 78 is supported inside the pipe body 4.

[0021] Working principle: When the utility model is used, the user places the pipe body 4 in the inner cavity of the pipe support 3 and pushes it steadily until the pipe is against the retaining frame 10, then the cylinder 5 extends to move the connecting frame 6 until the cross plate 71 is against the retaining frame 10, at this time the four expansion arc plates 78 all enter the inner cavity of the pipe body 4, then the motor 72 drives the threaded rod 73 to rotate, and the thread causes the threaded sleeve 74 to move to the right due to the thread, and the threaded sleeve 74 pushes the I-shaped slider 76 to move outward through the oblique rod 77, so that the four The expansion arc plates 78 are pressed against the inner side of the pipe body 4 to form an internal support for the pipe body 4 to prevent the pipe body 4 from deformation. Then the cutting device 2 works to cut off the pipe body 4. After cutting, the motor 72 reverses, causing the four expansion arc plates 78 to move toward each other, canceling the internal support. Then the cylinder 5 retracts, and the cut-off pipe body 4 is blocked by the retaining frame 10 until the expansion arc plates 78 are separated from the inner cavity of the pipe body 4.
