Description

Technical Field

[0001] This application relates to the technical field of shearing machines, and in particular to a blade positioning mechanism for a shearing machine. Background Technology

[0002] A cut pile machine is a key piece of equipment in the textile industry used to produce cut pile fabrics. Its core function is to cut the surface of the fabric with blades to create a pile effect.

[0003] refer to Figure 1 A cutting mechanism for a cutting fabric cutter includes a fixed frame 61, a drive roller 62 rotatably connected to the fixed frame 61, and a cutting blade 63 mounted on the drive roller 62. A drive motor is fixed to the fixed frame 61, and the output shaft of the drive motor is connected to the drive roller 62. When the drive motor is started, the output shaft of the drive motor drives the drive roller 62 to rotate, and the drive roller 62 drives the cutting blade 63 to rotate, thereby realizing the cutting operation on the fabric.

[0004] When the cutting blade 63 rotates, it will wobble. The wobble of the cutting blade 63 will cause the cutting position to shift during the cutting operation, thereby reducing the quality of the product after cutting. Utility Model Content

[0005] In order to improve the cutting quality of products, this application provides a blade positioning mechanism for a cutting machine.

[0006] The blade positioning mechanism for a shearing machine provided in this application adopts the following technical solution: A blade positioning mechanism for a shearing machine includes a support frame, a positioning block, and a connecting assembly. The positioning block is mounted on the support frame via the connecting assembly. A limiting hole is provided on the positioning block, and a portion of the shearing blade is located within the limiting hole.

[0007] By adopting the above technical solution, a portion of the cutting blade passes through the limiting hole and abuts against the side wall of the limiting hole. Then, the positioning block is connected to the support frame through the connecting assembly. The limiting hole on the positioning block can reduce the phenomenon of the cutting blade shaking, thereby reducing the phenomenon of poor cutting effect caused by the cutting blade shaking and improving the cutting quality of the product.

[0008] Optionally, the positioning block is provided with a separation block, and the end of the separation block away from the positioning block is provided in an arc shape.

[0009] By adopting the above technical solution, when the positioning block is connected to the connecting block, the separating block will abut against the fabric to be cut by the cutting blade. That is, the separating block first abuts against the fabric to be cut by the cutting blade, and then the cutting blade located below the positioning block cuts the fabric. The separating block can regulate the position of the fabric to be cut.

[0010] Optionally, the connecting component includes a connecting block disposed on the support frame, the connecting block having a slot, and the positioning block engaging with the slot.

[0011] By adopting the above technical solution, one end of the positioning block is engaged with the slot on the connecting block, thereby achieving the connection between the positioning block and the support frame.

[0012] Optionally, the connecting block has a first cavity communicating with the slot, and the connecting block is provided with a stabilizing mechanism, the stabilizing mechanism including a stabilizing block and a first adjusting component. There are two stabilizing blocks, and the positioning block is located between the two stabilizing blocks. The first adjusting component is provided on the connecting block, and both stabilizing blocks are connected to the first adjusting component.

[0013] By adopting the above technical solution, when the positioning block is inserted into the slot, the positioning block is located between the two stabilizing blocks; then the first adjustment component drives the two stabilizing blocks to move in opposite directions, so that the two stabilizing blocks are pressed against the positioning block located in the slot; the stabilizing mechanism can improve the stability of the positioning block on the connecting block.

[0014] Optionally, the first adjustment assembly includes a bidirectional lead screw, an adjustment plate, and a connecting bolt. The bidirectional lead screw passes through two of the stabilizing blocks, and the two stabilizing blocks are threadedly connected to both ends of the bidirectional lead screw. The adjustment plate is disposed on the bidirectional lead screw, and the connecting bolt passes through the adjustment plate and is threadedly connected to the connecting block.

[0015] By adopting the above technical solution, the adjusting plate is rotated, which drives the bidirectional lead screw to rotate. The bidirectional lead screw drives the two stabilizing blocks to move in opposite directions or away from each other. When both stabilizing blocks are pressed against the positioning block, the connecting bolt passes through the adjusting plate and is threadedly connected to the connecting block.

[0016] Optionally, the support frame is provided with a support block, and the positioning block abuts against the support block.

[0017] By adopting the above technical solution, when the positioning block is inserted into the connecting groove of the connecting block, the support block will press against the middle of the positioning block; the support block can support the positioning block, reduce the instability of the positioning block, and thus enable the positioning block to better limit the cutting blade.

[0018] Optionally, the support frame is provided with a lifting mechanism, which includes a lifting block and a lifting assembly. The lifting block is slidably disposed on the support frame, and the support block is disposed on the lifting block. The lifting assembly is disposed on the support frame and connected to the lifting block.

[0019] By adopting the above technical solution, the support block is located below the slot before the positioning block is inserted into the slot; after the positioning block is inserted into the slot, the lifting component is activated, the lifting component drives the lifting block to move, and the lifting block drives the support block to move towards the positioning block, so that the support block abuts against the positioning block; the lifting mechanism can reduce the phenomenon that the positioning block is inconvenient to insert into the slot when the support block abuts against the positioning block.

[0020] Optionally, the lifting assembly includes a lifting motor and a lifting screw. The lifting motor is mounted on the support frame, and the lifting screw is mounted on the output shaft of the lifting motor. The lifting screw passes through the lifting block and is threadedly connected to the lifting block.

[0021] By adopting the above technical solution, the lifting motor is started, and the output shaft of the lifting motor drives the lifting screw to rotate, which in turn drives the lifting block to move.

[0022] Optionally, the support block has a limiting groove for placing the positioning block, and the support block is provided with a limiting mechanism, which includes a limiting block and a second adjustment component. The limiting block is slidably disposed on the support block; the second adjustment component is disposed on the support block and connected to the support frame.

[0023] By adopting the above technical solution, before the positioning block is inserted into the slot, the positioning block passes through the limiting block and the support block; after the positioning block is inserted into the slot, the lifting block drives the support block to move towards the positioning block, the positioning block enters the limiting groove of the lifting block, and the side wall of the limiting groove abuts against the support block; when the support block moves, under the action of the second adjustment component, the limiting block will move towards the support block and abut against the support block and the positioning block; the limiting mechanism can improve the stability of the positioning block on the support block.

[0024] Optionally, the second adjustment assembly includes a first adjustment rack, an adjustment shaft, a first adjustment gear, a second adjustment gear, and a second adjustment rack. The first adjustment rack is disposed on the limiting block, the adjustment shaft is rotatably disposed on the support block, the first adjustment gear is keyed to the adjustment shaft and meshes with the first adjustment gear, the second adjustment gear is keyed to the adjustment shaft, and the second adjustment rack is disposed on the support frame and meshes with the second adjustment gear.

[0025] By adopting the above technical solution, when the support block moves toward the positioning block, the second adjusting gear will rotate relative to the second adjusting rack. The second adjusting gear drives the adjusting shaft to rotate, and the first adjusting gear on the adjusting shaft drives the first adjusting rack to move. The first adjusting rack will then drive the limiting block to move toward the support block.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The limiting holes on the positioning block can reduce the shaking of the cutting blade, thereby reducing the poor cutting effect caused by the shaking of the cutting blade and improving the cutting quality of the product; 2. The support block can support the positioning block, reducing the instability of the positioning block, thereby allowing the positioning block to better constrain the cutting blade; 3. The lifting mechanism can reduce the phenomenon that the positioning block is inconvenient to insert into the slot when the support block is pressing against the positioning block.

A connecting component is provided at the end of the support frame 11 away from the shearing blade 63. A positioning block 12 is provided on the connecting component. A limiting hole 121 is provided on the positioning block 12, and a portion of the shearing blade 63 passes through the limiting hole 121. A separating block 14 is fixedly connected to the end of the positioning block 12 away from the connecting component. The end of the separating block 14 away from the positioning block 12 is provided in an arc shape. A support block 3 is provided on the support frame 11 to support the positioning block 12.

[0032] refer to Figure 2 and Figure 4 The connecting component includes a connecting block 13, which is fixedly connected to the end of the support frame 11 away from the cutting blade 63; the connecting block 13 has a slot 131 on the side near the cutting blade 63 that engages with the positioning block 12.

[0033] The connecting block 13 has a first cavity 132 communicating with the slot 131. The connecting block 13 is provided with a stabilizing mechanism 2, which includes two stabilizing blocks 21 that are slidably connected in the first cavity 132. When the positioning block 12 is engaged with the slot 131 on the connecting block 13, the positioning block 12 is located between the two stabilizing blocks 21. A first adjustment component 22 is provided on the connecting block 13. The first adjustment component 22 includes a bidirectional lead screw 221, which passes through two stabilizing blocks 21, and the two ends of the two stabilizing blocks 21 are respectively threaded to the two ends of the bidirectional lead screw 221. One end of the bidirectional lead screw 221 passes through the connecting block 13 and is located outside the connecting block 13. An adjustment plate 222 is fixedly connected to the bidirectional lead screw 221 located outside the connecting block 13. A first through hole is opened on the adjustment plate 222, and a threaded hole is opened on the connecting block 13. A connecting bolt 223 is provided on the adjustment plate 222, and the connecting bolt 223 passes through the first through hole on the adjustment plate 222 and is threaded to the threaded hole on the connecting block 13.

[0034] Initially, before the positioning block 12 is engaged with the slot 131 on the connecting block 13, the connecting bolt 223 is threadedly connected to the threaded hole on the connecting block 13. When the positioning block 12 needs to be installed on the connecting block 13, the end of the positioning block 12 away from the separating block 14 is fully engaged with the slot on the connecting block 13; then the connecting bolt 223 is rotated to separate it from the threaded hole on the connecting block 13; next, the adjusting plate 222 is rotated, which drives the bidirectional lead screw 221 to rotate, and the bidirectional lead screw 221 drives the two stabilizing blocks 21 to move in opposite directions, so that the two stabilizing blocks 21 respectively abut against the two opposite side walls of the positioning block 12; when both stabilizing blocks 21 abut against the positioning block 12, the adjusting plate 222 rotates one revolution, that is, the axis of the first through hole on the adjusting plate 222 is aligned with the axis of the threaded hole on the connecting block 13; finally, the connecting bolt 223 is rotated again to thread it into the threaded hole on the connecting block 13.

[0035] refer to Figure 2 and Figure 5 The support block 3 is located between the connecting block 13 and the cutting blade 63. The upper end of the support block 3 is provided with a limiting groove 31, and the positioning block 12 is engaged with the limiting groove 31.

[0036] refer to Figure 5 and Figure 6 The support frame 11 has a first sliding groove 111, and a lifting mechanism 4 is provided on the support frame 11. The lifting mechanism 4 includes a lifting block 41 slidably connected in the first sliding groove 111, and a support block 3 is threadedly connected to the lifting block 41. The support frame 11 is provided with a lifting assembly 42, which includes a lifting screw 422 rotatably connected in the first sliding groove 111. The lifting screw 422 passes through the lifting block 41 and is threadedly connected to the lifting block 41. A lifting motor 421 is fixedly connected to the support frame 11, and the output shaft of the lifting motor 421 is connected to one end of the lifting screw 422.

[0037] The support block 3 is provided with a limiting mechanism 5, which includes a limiting block 51 located above the support block 3. The limiting block 51 can abut against the support block 3, thereby better limiting the positioning block 12 within the limiting groove 31 of the support block 3. The support block 3 has a second cavity 32 and a second through hole communicating with the second cavity 32. The support frame 11 has a second sliding groove 112. The support block 3 is provided with a second adjustment component 52, which includes a first adjustment rack 521. One end of the first adjustment rack 521 is connected to the limiting block 51 and the other end passes through the second through hole on the support block 3 and is located in the second cavity 32 of the support block 3. An adjustment shaft 522 is rotatably connected to the support block 3. One end of the adjustment shaft 522 is located in the second cavity 32 of the support block 3 and the other end passes through the support block 3 and is located in the second sliding groove 112 of the support frame 11. A first adjustment gear 523 that meshes with the first adjustment rack 521 is keyed to the adjustment shaft 522 located in the second cavity 32 of the support block 3. A second adjustment gear 524 that meshes with the second adjustment gear 524 is keyed to the adjustment shaft 522 located in the second sliding groove 112 of the support frame 11. A second adjustment rack 525 that meshes with the second adjustment gear 524 is fixedly connected to the side wall of the second sliding groove 112.

[0038] After the positioning block 12 is connected to the connecting block 13, the connecting block 13 is located between the limiting block 51 and the support block 3. The lifting motor 421 is started, and the output group of the lifting motor 421 drives the lifting screw 422 to rotate. The lifting screw 422 drives the lifting block 41 to move towards the positioning block 12 in the first sliding groove 111 of the support frame 11. The lifting block 41 drives the support block 3 to move towards the positioning block 12, so that the positioning block 12 enters the limiting groove 31 of the support block 3. The bottom wall of the limiting groove 31 will abut against the positioning block 12, and the side wall of the limiting groove 31 will also abut against the positioning block 12. When the lifting block 41 moves toward the support block 3, the second adjusting gear 524 rotates relative to the second adjusting rack 525. The second adjusting gear 524 drives the adjusting shaft 522 to rotate, the adjusting shaft 522 drives the first adjusting gear 523 to rotate, the first adjusting gear 523 drives the first adjusting rack 521 to move, and the first adjusting rack 521 drives the limiting block 51 to move toward the support block 3, so that the limiting block 51 abuts against the support block 3 and the positioning block 12, thereby limiting the positioning block 12 in the limiting groove 31 of the support block 3.

[0039] The implementation principle of the blade positioning mechanism of the shearing machine in this application embodiment is as follows: at the beginning, there is a certain distance between the limiting block 51 and the support block 3.

[0040] First, pass a portion of the cutting blade 63 through the limiting hole 121 on the positioning block 12, so that the cutting blade 63 abuts against the side wall of the limiting hole 121; then, pass the end of the positioning block 12 away from the separating block 14 through the space between the limiting block 51 and the support block 3 and engage with the slot 131 on the connecting block 13; then, make both stabilizing blocks 21 abut against the positioning block 12; finally, make the positioning block 12 located in the limiting groove 31 of the support block 3, and make the limiting block 51 abut against the support block 3.

[0041] When the positioning block 12 is connected to the connecting block 13, the separating block 14 will abut against the fabric to be cut by the cutting blade 63. That is, the separating block 14 first abuts against the fabric to be cut by the cutting blade 63, and then the cutting blade 63 located below the positioning block 12 cuts the fabric.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
