Description

Technical Field

[0001] The invention relates to the technical field of casing processing, in particular to a cutting device for casing processing. Background Art

[0002] Intestine casings are livestock products made by scraping the large and small intestines of livestock. They are mainly used as the outer casing for stuffing sausages and sausages; sheep casings can also be made into gut for making tennis racket strings, bowstrings, and surgical sutures. Intestine casings are divided into pig casings, sheep casings, and cattle casings according to the type of animal. They are divided into large intestine casings and small intestine casings according to the part of the body.

[0003] According to the cutting device for casing processing described in Patent No. CN115251127A, the casing migration is not convenient during use. After a section of casing is cut, the casing cannot be quickly pulled through in sequence and cannot be effectively straightened. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a cutting device for casing processing, which solves the above-mentioned problems.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: A cutting device for processing casings, comprising a cutting box and a feeding channel fixed to one side of the cutting box, the inner cavity of the cutting box is provided with a conveying and cutting mechanism for conveying casings, and a traction mechanism for traction of casings is passed through the middle of the conveying mechanism;

[0006] The conveying and cutting mechanism comprises a frame with hollow parts on both sides, the inner cavity of the frame is rotatably connected to a lower conveying roller driven by a motor, the inner cavity of the frame is slidably connected to an upper conveying roller driven by a motor through a sliding groove, one side of the shaft end of the upper conveying roller is fixedly connected to a return spring fixed to the inner cavity of the sliding groove, the right side of the frame is fixedly connected to a guide plate located at the lower right of the lower conveying roller, and one side of the guide plate is fixedly connected to a cutting assembly;

[0007] The traction mechanism comprises a traction frame penetrating the inner cavity of the frame, one end of the traction frame penetrating and extending to the top of the feed channel, and the inner cavity of the traction frame is slidably connected with a casing clamping structure driven by a driving structure;

A flat surface is provided on one side of the stretching roller, and the roller surface of the stretching roller abuts against the surface of the guide plate when rotating. When the casings need to be pulled during use, the driving structures on both sides release a pull rope and tighten the pull rope to drive the traction platform to slide left and right in the traction frame, and drive the traction platform to move to the left. When it moves to the inner cavity of the frame, the top plate abuts against the abutment plate at the end of the roller shaft of the upper conveying roller, and the upper conveying roller is lifted up. At this time, the upper conveying roller squeezes the reset spring upward in the sliding groove to move, and then the traction platform passes through, and the ends of the casings are respectively placed in different separation grooves, and then the cylinder The rotation drives the clamping plate to rotate, clamping the casing on the traction table, and then the traction table is driven to be retracted through the driving mechanism, and then the traction table releases the clamping of the casing, and the casing droops under the action of gravity, and then continues to be conveyed downward along the surface of the guide plate.
