[0026] For the purpose of simplicity and illustration, the principles of the embodiments are mainly described by reference to examples. In the following description, many specific details are proposed to provide a thorough understanding of the embodiments. However, it is obvious that for those of ordinary skill in the art, these embodiments may not be limited to these specific details in practice. In some instances, known methods and structures are not described in detail to avoid making these embodiments unnecessarily difficult to understand. In addition, all embodiments can be used in combination with each other.

[0027] See also Figures 1 to 6 , the utility model provides a technical solution:

[0028] Embodiment 1, a flat knife specially used for a corduroy fabric shearing machine, comprising:

[0029] The first flat blade plate 2 and the second flat blade plate 3 are both slidably installed in the inner cavity of the blade holder 1. Figure 2 As shown, the first flat blade plate 2 and the second flat blade plate 3 can slide relative to the mounting blade holder 1 along their own length direction, and a plurality of saw teeth 21 distributed at equal intervals are arranged on one end edge of the first flat blade plate 2, and the saw teeth 21 are pressed against the surface of the knitted fabric, and thick and wide strips of velvet can be formed on the surface of the knitted fabric, and a guide slot 22 distributed at intervals with the plurality of saw teeth 21 is provided inside the first flat blade plate 2;

[0030] Secondly, a strip plate 32 is provided between two adjacent saw teeth 21, and the strip plate 32 is slidably installed in the inner cavity of the guide slide groove 22, and the strip plate 32 is fixedly connected to the second flat knife plate 3, and one end of the strip plate 32 is set to be pointed and flush with the saw teeth 21, and the second flat knife plate 3 and the first flat knife plate 2 can slide relative to each other, and during the relative sliding, the end of the strip plate 32 and the saw teeth 21 can be staggered with each other, which is specifically manifested as follows: ① When the end of the strip plate 32 and the saw teeth 21 are flush, the two cooperate with each other to form strip pile on the surface of the knitted fabric, thereby reducing the width of the strip pile, and obtaining ① When the strip plate 32 moves away from the knitted cloth, only the saw teeth 21 are in contact with the surface of the knitted cloth, and at this time, the saw teeth 21 will form a group of relatively thick and wide strip pile on the surface of the knitted cloth; ③ When the saw teeth 21 move away from the knitted cloth, only the tip of the strip plate 32 is in contact with the surface of the knitted cloth, and at this time, the tip of the strip plate 32 forms another group of relatively thick and wide strip pile on the surface of the knitted cloth, and the distribution position of the strip pile is different from that in ②; therefore, the flat knife of the device can change the position and width of the strip pile on the surface of the knitted cloth without stopping the wool shearing machine, and has a good range of application.

[0031] In order to limit the sliding of the strip plate 32, the present application also has a through groove 23 on the surface of the first flat blade plate 2, and the through groove 23 is provided with a plurality of guide grooves 22 respectively connected to each other. The other end of the strip plate 32 is fixedly connected to a connecting platform 31, and the connecting platform 31 passes through the through groove 23 and is fixedly connected to the second flat blade plate 3. The second flat blade plate 3 and the first flat blade plate 2 are fitted together. Figure 6 and Figure 5 As shown, the strip plate 32 and the second flat blade plate 3 are fixedly connected via the connecting platform 31, and the through groove 23 can limit the sliding of the connecting platform 31, thereby limiting the sliding of the strip plate 32 and the second flat blade plate 3, and at the same time, the guide groove 22 can also limit the sliding of the strip plate 32 to a certain length.

[0032] In order to limit the sliding of the second flat blade plate 3 and the first flat blade plate 2, the present application also has grooves provided at the places where the second flat blade plate 3 and the first flat blade plate 2 are attached to each other, and the two grooves are spliced ​​together to form a limiting slide groove 4, such as Figure 6 As shown, the opening of the groove will not affect the relative sliding between the second flat blade plate 3 and the first flat blade plate 2. The inner middle part of the installation tool holder 1 is fixedly connected with a limit cross piece 101, which passes through the limit slide groove 4, and the width of the limit cross piece 101 is smaller than the width of the limit slide groove 4. Figure 6 , Figure 3 and Figure 2 As shown, the setting of the limiting horizontal piece 101 can limit the sliding of the second flat blade plate 3 and the first flat blade plate 2, and can prevent the second flat blade plate 3 and the first flat blade plate 2 from being separated from the mounting blade holder 1.

[0033] In order to adjust the position of the first flat blade plate 2 and the second flat blade plate 3 relative to the installation knife holder 1, the present application also has a supporting plate 1 5 and a supporting plate 2 6 arranged side by side in the inner cavity of the limiting slide groove 4, the supporting plate 1 5 and the supporting plate 2 6 are both in contact with the side of the limiting horizontal piece 101, the supporting plate 1 5 is against the inner wall of the groove on the first flat blade plate 2, and the supporting plate 2 6 is against the inner wall of the groove on the second flat blade plate 3, combined with Figure 2 , Figure 4 and Figure 6 As shown, when the support plate 1 5 is inserted into the inner cavity of the limiting slide groove 4, the limiting cross piece 101 cooperates with the support plate 1 5 to position the first flat knife plate 2, so that the first flat knife plate 2 and the mounting knife holder 1 remain relatively fixed. When the support plate 2 6 is inserted into the inner cavity of the limiting slide groove 4, the limiting cross piece 101 cooperates with the support plate 2 6 to position the second flat knife plate 3, so that the second flat knife plate 3 and the mounting knife holder 1 remain relatively fixed. By pulling the support plate 1 5 or the support plate 2 6 out of the inner cavity of the limiting slide groove 4, the first flat knife plate 2 or the second flat knife plate 3 can be moved a certain distance away from the knitted cloth, so as to change the width and position of the strip velvet formed on the surface of the knitted cloth.

[0034] In order to prevent support plate 1 5 and support plate 2 6 from falling easily from the inner cavity of the limiting slide groove 4, the present application also has a baffle 7 fixedly connected to one end of support plate 1 5 and one end of support plate 2 6, and the two baffles 7 are respectively located at the two ends of the tool holder 1. The baffle 7 is used to position the positions of support plate 1 5 and support plate 2 6, so that support plate 1 5 and support plate 2 6 can respectively resist the baffle 7 installed at the other end, thereby preventing them from falling easily from the inner cavity of the limiting slide groove 4.

[0035] In order to install the flat knife, the present application also has mounting convex plates 102 fixedly arranged at both ends of the mounting knife holder 1, and is mounted on the shearing machine base by bolts. The shearing machine is provided with a circular knife 8 and a cloth support knife 9, such as Figure 1 As shown, the cloth-supporting knife 9 supports the knitted cloth, and the flat knife, the round knife 8 and the cloth-supporting knife 9 cooperate to form strip pile on the surface of the knitted cloth.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
