Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a stepless adjustment mechanism for cutting gauze. Background Art

[0002] The gauze cutting mechanism is a mechanical device used to cut large pieces of gauze into required sizes. In the process of mass transmission and cutting of gauze, the assembly line method is generally adopted to cut and roll the wider gauze. The cutting knife is located between two conveying rollers, and the gauze is tensioned and transmitted. The cutting knife remains stationary to cut the gauze. It can quickly and accurately cut large pieces of gauze into required sizes, improve production efficiency, reduce the workload of manual cutting, and reduce production costs.

[0003] However, at present, when cutting gauze, the cutting knife is generally fixed on the knife holder, and it is difficult to more accurately adjust the position of the cutting knife according to the cutting width specification requirements of the gauze; at the same time, when a part of the cutting knife cuts the gauze for a long time, it is inevitable that the part will become blunt, and the knife is generally adjusted by rotating. However, when rotating the knife, the rotation angle of the knife is difficult to accurately control and check, which easily leads to the part of the knife not being used or the part of the knife being used for too long. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a stepless adjustment mechanism for cutting gauze to solve the problem that the cutting knife is generally fixedly mounted on a knife holder, making it difficult to more accurately adjust the position of the cutting knife according to the cutting width specification requirements of the gauze.

[0005] In order to achieve the above-mentioned purpose, the basic scheme of the utility model is as follows: a gauze cutting stepless adjustment mechanism, comprising:

[0006] A rotation control tube, the end of which is provided with rotation angle scale lines;

[0007] The tool holder is in an arc shape and is coaxially mounted on the rotating control tube;

[0008] The tool is coaxially and detachably connected to the tool holder;

[0009] A slide plate, the slide plate is fixedly mounted on the tool holder, and the rotation control tube is provided with a first slide groove for the slide plate to slide along the axial direction;

[0010] The bolt can pass through the slide plate and abut against the inner wall of the first slide groove of the rotation control tube.

[0011] The technical principle of the utility model is: when adjusting the position of the tool holder and the tool on the rotating control tube, the bolt is loosened, and the tool holder is pushed to move. At this time, the slide slides in the first slide groove, and the first slide groove can limit the horizontal sliding of the slide, the tool holder and the tool along the rotating control tube; after the tool holder and the tool are moved to the required position, the bolt presses the slide into the first slide groove again to achieve accurate and stable fixation of the tool holder and the tool. In this process, the cooperation of the slide and the first slide groove can realize stepless adjustment of the installation position of the tool holder and the tool, and accurate adjustment of the position of the tool holder and the tool can be achieved.

[0012] When the cutter is cutting the gauze, the slide can stably abut against the side wall of the first slide groove, thereby improving the stability of the cutter holder and the cutter installed on the rotating control tube.

[0013] When a part of the tool becomes dull after long-term use, the rotation control tube on the support frame is rotated. By rotating the rotation angle scale line on the rotation control tube and controlling the rotation of the rotation control tube, the rotation angle of the tool can be accurately controlled, so that each part of the tool can be fully utilized.

[0014] Furthermore, the bottom of the first slide groove of the rotation control tube is covered with an anti-skid sheet, which can abut against the bolt.

[0015] Through the above arrangement, when the sliding plate and the inner wall of the first sliding groove are fixed, the bolts can stably abut against the anti-slip plate, thereby achieving more stable installation of the sliding plate, the tool holder and the tool.

[0016] Furthermore, the cross-sectional profiles of the tool holder and the tool are both semicircular arc-shaped, and the ends of the two tool holders can be joined together to abut against each other, and the ends of the two tools can also be joined together to abut against each other.

[0017] Through the above arrangement, when installing the slide, the tool holder and the tool, the two tool holders and the tool can be installed together or separately according to the needs, which is more adaptable to installation and use.

[0018] Furthermore, the rotation control tube is axially provided with a second slide groove connected to the rotation control tube, and the axis of the first slide groove is parallel to the axis of the second slide groove; a first flange that can slide along the second slide groove is fixedly provided on one side of the tool holder close to the rotation control tube.

[0019] Through the above arrangement, the second slide groove can cooperate with the first flange to guide and limit the horizontal sliding of the tool holder and the tool, making the horizontal sliding of the tool holder and the tool more precise; at the same time, the second slide groove allows the rotating control tube to achieve the effect of reducing weight and reducing costs.

[0020] Furthermore, the number of the first sliding grooves is two, and the two first sliding grooves are symmetrically arranged along the axis of the second sliding groove.

[0021] Through the above arrangement, the two first slide grooves located on both sides of the second slide groove can cooperate with the slide more accurately and stably, so that the installation of the tool holder and the tool is more balanced and stable.

[0022] Furthermore, a first mounting cavity for embedding the tool is provided on the side of the tool holder away from the rotation control tube, a second mounting cavity connected to the first mounting cavity is provided in the first flange, and a second flange that can be embedded in the second mounting cavity is integrally formed on the side of the tool close to the rotation control tube.

[0023] Through the above arrangement, when installing the tool, the side of the tool close to the rotation control tube is embedded in the first installation cavity, and the second flange of the tool is installed in the second installation cavity, which can also provide more stable installation and positioning for the tool.

[0024] Furthermore, a mounting hole is overlapped and penetrated at the first flange and the second flange, and a locking member is detachably mounted at the mounting hole.

[0025] Through the above arrangement, when the mounting holes of the first flange and the second flange overlap, the tool and the tool holder can be locked and fixed by using a locking member, so that the tool can be easily installed.

[0026] Furthermore, the second slide groove and the two first slide grooves constitute a limiting portion, the number of the limiting portions is two, and the two limiting portions are symmetrically arranged along the central axis of the rotation control tube.

[0027] Through the above arrangement, the two cutters and the cutter holder assembled into a circle can be installed from the outer wall of the rotating control tube, so that the two cutters and the cutter holder assembled can be accurately installed. BRIEF DESCRIPTION OF THE DRAWINGS
