[0020] The present invention is described in detail with respect to specific embodiments in order to enable those skilled in the art to understand the present invention. However, it should be understood that the present invention is not limited to the scope of the specific embodiments. For those skilled in the art, any changes that are within the spirit and scope of the present invention as defined and determined by the appended claims are obvious. All utility model creations utilizing the concept of the present invention are protected.

[0021] Example 1

[0022] This embodiment provides a yarn cutting device, the purpose of which is to solve the problem of low efficiency in the existing manual cutting of textile yarns using scissors during the production process. (Reference) Figures 1-4 The specific structure of this embodiment will be described in detail below.

[0023] A yarn cutting device includes a base plate 1 and a blade 2.

[0024] Among them, support columns 3 are provided at both ends of the upper surface of the base plate 1; tool holders 4 are symmetrically provided at the top of the two support columns 3, and the blade 2 is located between the two tool holders 4.

[0025] Specifically, the tool holder 4 includes a fixed cylinder 5 located at the top of the support column 3, and a clamping plate 6 is movably disposed inside the fixed cylinder 5. One end of the blade 2 is disposed on the clamping plate 6.

[0026] In this embodiment, the base plate 1 provides bottom balance and support for the two support columns 3. A clamping plate 6 is movably installed on the top of the support column 3 through a fixed cylinder 5. The clamping plate 6 can move left and right within the fixed cylinder 5 to adjust the relative distance between the two clamping plates 6 to accommodate blades 2 of different lengths and facilitate the installation of the blades 2. The cutting edge of the blade 2 faces upward. When it is necessary to cut the yarn, simply place the yarn on the cutting edge of the blade 2 and pull the yarn on both sides of the cutting edge downward to cut the yarn, thereby improving the working efficiency of abrasive thread cutting. The structure is simple and the operation is convenient.

[0027] Specifically, the clamping plate 6 includes a clamping plate 61 and a fixing plate 62. Both the upper and lower ends of the clamping plate 61 and the fixing plate 62 are provided with first through holes 63. One end of the blade 2 is clamped between the clamping plate 61 and the fixing plate 62 by passing a bolt through the first through hole 63 and fixing it with a nut.

[0028] Specifically, the clamping plate 61 has an inner side with a mounting post 64, and the fixing plate 62 has an inner side with a limiting hole 65 that matches the mounting post 64. One end of the blade 2 is sleeved on the mounting post 64, and the mounting post 64 is embedded in the limiting hole 65.

[0029] In this embodiment, a mounting post 64 is provided in the middle of the inner side of the clamping plate 61. One end of the blade 2 has a through hole pre-drilled for the mounting post 64, and the through hole is fitted onto the mounting post 64, thereby fitting one end of the blade 2 onto the mounting post 64. A limiting hole 65 corresponding to the mounting post 64 is provided on the inner side of the fixing plate 62 opposite to the mounting post 64. The depth of the limiting hole 65 is greater than the height of the mounting post 64, so the mounting post 64 is embedded in the limiting hole 65, clamping the end of the blade 2.

[0030] Above and below the mounting post 64 and the limiting hole 65, the clamping plate 61 and the fixing plate 62 are both provided with a through first hole 63. The clamping plate 61 and the fixing plate 62 are connected by bolts passing through the first through hole 63 and connected to the nut, so that the clamping plate 61 and the fixing plate 62 can further clamp the end of the fixing blade 2.

[0031] Specifically, a screw 66 is provided on one side of the clamping plate 61. The screw 66 is inserted into the fixing cylinder 5 and fastened by the locking nut 67.

[0032] In this embodiment, a screw 66 is provided in the middle of the side of the clamping plate 61 near the fixed cylinder 5. The screw 66 passes through the through hole in the middle of the fixed cylinder 5, and the screw 66 is fixed to the fixed cylinder 5 at both ends by locking nuts 67.

[0033] Specifically, each of the two tool holders 4 is equipped with a cover plate 7. The cover plate 7 and the support column 3 are provided with corresponding second through holes 8, and a pin is inserted into the second through hole 8.

[0034] In this embodiment, a cover plate 7 is provided on both blade holders 4. The cover plate 7 is U-shaped and is used to cover the cutting edge of the blade 2 to prevent accidental injury to others and to prevent damage to the cutting edge of the blade 2. When it is necessary to cut yarn, the cover plate 7 can be removed for operation.

[0035] A corresponding second through hole 8 is provided on the cover plate 7 and the support column 3. A pin is inserted into the second through hole 8 to prevent the cover plate 7 from falling off.

[0036] Although the specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this patent. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this patent.
