Description

Technical Field

[0001] This utility model belongs to the field of cutting bed technology, and specifically refers to a cutting blade connection structure for a cutting bed. Background Technology

[0002] A cutting table is a cutting device used for automatically cutting fabric pieces, widely used in industries such as textiles and apparel, automotive interiors, furniture, bags, and outdoor products. Typically, a cutting table is equipped with a high-speed rotating cutting blade that travels along a pre-designed trajectory. The blade needs to rotate during the cutting process to produce the desired shape. Most cutting blades on the market have a connecting structure consisting of a guide sleeve, a blade holder, and a drive rod. The drive rod moves the guide sleeve up and down, and the blade holder is located inside the guide sleeve. The guide sleeve consists of a guide sleeve body and a fixing component. A groove for the blade holder to rotate is provided between the guide sleeve body and the fixing component. The fixing component is connected to the guide sleeve body by bolts, allowing the blade holder to rotate during cutting. However, the guide sleeve body and the fixing component require high precision in their fit; insufficient precision can easily cause the blade holder to jam during rotation, thus increasing manufacturing costs. Utility Model Content

[0003] The purpose of this invention is to provide a cutting blade connection structure for a cutting bed that is both structurally sound and simple, and reduces manufacturing costs and difficulty through other means.

[0004] The purpose of this utility model is achieved as follows:

[0005] A cutting blade connection structure for a cutting bed includes a drive rod, a sliding sleeve, and a blade handle. One end of the drive rod is rotatably connected to the sliding sleeve, and the other end is connected to a drive device. The blade handle is rotatably disposed within the sliding sleeve, and a limit block is provided within the sliding sleeve, with the limit block located above the blade handle.

[0006] In the above-mentioned cutting bed cutter connection structure, the cutter handle includes a cutter handle connecting post and a rotating post connected to each other. The cutter handle connecting post is provided with a cutter fixing groove, the cutter fixing groove is provided with a fixing hole, and the sliding sleeve is provided with a rotating groove to accommodate the rotating post.

[0007] In the cutting blade connection structure of the cutting bed described above, the sliding sleeve has a receiving groove for accommodating the limiting block, and the receiving groove extends through the sliding sleeve.

[0008] In the cutting blade connection structure of the cutting bed described above, the limiting block is in contact with the upper side of the rotating column.

[0009] In the cutting blade connection structure of the cutting bed described above, the bottom surface of the rotating groove is located on one side of the central axis of the rotating column.

[0010] In the cutting blade connection structure of the cutting bed described above, the end of the limiting block is located in the receiving groove.

[0011] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0012] This invention features a rotating groove in the sliding sleeve for the knife handle to rotate, with the connection between the knife handle and the cutting knife exposed outside the sliding sleeve. The sliding sleeve also has a limiting block to prevent the knife handle from falling off, and the limiting block does not interfere with the rotation of the knife handle. The sliding sleeve can also move up and down via a drive rod. Compared with the prior art, this design is simpler in structure and easier to install and operate. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] like Figures 1-4 The diagram shows a cutting blade connection structure for a cutting bed, comprising a drive rod 1, a sliding sleeve 2, and a blade handle 3. One end of the drive rod 1 is rotatably connected to the sliding sleeve 2, and the other end is connected to a drive device. The blade handle 3 is rotatably disposed within the sliding sleeve 2, and a limiting block 4 is provided within the sliding sleeve 2, located above the blade handle 3. This invention provides a rotating groove for the blade handle to rotate within the sliding sleeve, with the connection point between the blade handle and the cutting blade exposed outside the sliding sleeve. The sliding sleeve also has a limiting block to prevent the blade handle from falling off, and the limiting block does not interfere with the rotation of the blade handle. The sliding sleeve can also move up and down via the drive rod. Compared to existing technologies, this design is simpler and easier to install and operate.

[0020] In the above-mentioned cutting blade connection structure of the cutting bed, the blade handle 3 includes a blade handle connecting post 31 and a rotating post 32 connected to each other. The blade handle connecting post 31 is provided with a cutting blade fixing groove 33, and the cutting blade fixing groove 33 is provided with a fixing hole 34. The sliding sleeve 2 is provided with a rotating groove 21 for accommodating the rotating post 32. Specifically, the diameter of the rotating post is larger than the diameter of the blade handle connecting post, which plays a role in limiting and preventing it from falling off. The blade handle connecting post extends out of the sliding sleeve for fixed connection with the cutting blade.

[0021] In the cutting blade connection structure of the cutting bed described above, the sliding sleeve 2 has a receiving groove 22 for accommodating the limiting block 4. The receiving groove 22 penetrates the sliding sleeve 2. Specifically, this is to facilitate the installation of the limiting block.

[0022] In the cutting blade connection structure of the cutting bed described above, the limiting block 4 contacts the upper side of the rotating column 32. Specifically, this is to prevent the blade handle from moving up and down and to ensure cutting accuracy.

[0023] In the cutting blade connection structure of the cutting bed described above, the bottom surface 211 of the rotating groove 21 is located on one side of the central axis of the rotating column 32. Specifically, this is to ensure that the cutting blade is located at the center of the rotating column, so that the cutting blade can rotate during cutting.

[0024] In the cutting blade connection structure of the cutting bed described above, the end of the limiting block 4 is located inside the receiving groove 22. Specifically, this is to avoid the limiting block being exposed and interfering with other accessories.

[0025] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
