[0021] Beneficial Effects

[0022] Compared with the prior art, the advantages of the present invention are:

[0023] 1. The utility model provides a movable frame and a limiting tube. By pressing the guide column, the conical block is moved to the top of the limiting tube. After the conical block is no longer in contact with the limiting ball, the limiting tube can be quickly inserted into the movable frame. After the force applied to the guide column is cancelled, the conical block returns to its original position. After the limiting ball is in contact with the conical block, the limiting ball can be stuck on the outer surface of the movable frame, thereby quickly fixing the limiting tube in the movable frame and fixing the blade in the connecting tube. This solution makes the operation simpler when replacing the blade, reduces the conflict between the wrench and other parts, and avoids the situation where the wrench accidentally damages other parts.

[0024] 2. Based on beneficial effect 1, with the coordinated use of the storage component, under the elastic force of the second spring, a pulling force is applied to the limit plate, so that after the limit plate is pulled back to a certain distance, the new blade is stored in the storage slot, and the old blade is removed from the connecting pipe, and then a pulling force is applied to the limit plate to take the new blade out of the limit frame and place the old blade in the limit frame. This scheme can limit the placement of the new blade to avoid accidentally knocking the new blade off the equipment when disassembling the blade, causing damage to the new blade and affecting the subsequent normal use of the blade. The old blade is stored in the limit frame to avoid the blade falling from the equipment and endangering the health of the workers.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Embodiment 1

[0040] See also Figure 1-Figure 3 , Figure 5 As shown, this embodiment is a cutting mechanism of a resistance wire winding machine, comprising:

[0041] The main body assembly includes a lower support plate 16;

[0042] The limiting assembly includes a movable frame 21, a limiting tube 22 movably connected to the inside of the movable frame 21, a limiting column 23 movably connected to the inside of the limiting tube 22, a fixing rod 27 fixed to a side surface of the limiting column 23, a conical block 28 fixed to a side surface of the fixing rod 27, and a limiting ball 29 movably connected to the inside of one side of the limiting tube 22;

[0043] The storage assembly includes a limit frame 31 fixed to the middle of the upper surface of the lower support plate 16

[0044] A fixing block 24 is fixed to the other side surface of the limiting column 23, a guide column 25 is fixed to the other side surface of the fixing block 24, a first spring 241 is fixed to one side surface of the fixing block 24, the other side of the first spring 241 is used to fix the limiting tube 22, and a shell 26 is fixed to the other side outer surface of the limiting tube 22;

[0045] Wherein, the guide column 25 is located inside the housing 26;

[0046] The fixing block 24 receives and installs the guide column 25, and then receives and installs the limiting column 23. Under the elastic force of the first spring 241, the limiting column 23 can be pushed, so that the conical block 28 is displaced inside the limiting tube 22. The housing 26 is provided to protect the first spring 241 and the guide column 25, so as to prevent the first spring 241 and the guide column 25 from being accidentally damaged.

[0047] The main assembly also includes a second cylinder 161 fixed to one side of the lower surface of the lower support plate 16, a second transmission shaft 162 fixed to the output end of the second cylinder 161, a connecting pipe 164 fixed to the outer surface of the top end of the second transmission shaft 162, and a blade 163 movably connected to the inside of the connecting pipe 164;

[0048] The interior of the blade 163 fits with the limiting tube 22;

[0049] The second cylinder 161 is provided to drive the second transmission shaft 162 to move upward, thereby linking the blade 163 provided inside the connecting tube 164 to move upward synchronously to cut the wound resistance wire. The connecting tube 164 receives and installs the second transmission shaft 162, and then receives and installs the blade 163.

[0050] A connecting column 12 is fixed to the outer surface of the other side of the lower support plate 16, a guide frame 13 is fixed to the outer surface of the upper end of the connecting column 12, and a connecting frame 14 is fixed to the outer surface of the lower end of the connecting column 12;

[0051] The connecting column 12 is used to receive and install the lower support plate 16, and then receive and install the upper support plate 15. The guide frame 13 is used to connect and install the lead screw nut, so that the blade 163 moves synchronously with the winding mechanism. The connecting frame 14 is connected to the guide rod, so that the connecting column 12 moves more smoothly when moving left and right.

[0052] An upper support plate 15 is fixed to the outer surface of the top of the connecting column 12, a first cylinder 151 is fixed to one side of the upper surface of the upper support plate 15, a first transmission shaft 152 is fixed to the output end of the first cylinder 151, a connecting rod 153 is fixed to the lower surface of the first transmission shaft 152, and a pressing column 154 is fixed inside the bottom end of the connecting rod 153;

[0053] The upper support plate 15 is provided to receive and install the connecting column 12, and then receive and install the first cylinder 151. Under the action of the first cylinder 151, the first transmission shaft 152 drives the connecting rod 153 to move downward, so that the pressing column 154 moves downward synchronously. After the pressing column 154 fixes one end of the resistance wire on the steel pipe, when the resistance wire winding is completed, the pressing column 154 is pressed down again to fix the other end of the resistance wire on the steel pipe, thereby completing the winding production of the resistance wire;

[0054] Working principle:

[0055] When removing the old blade 163;

[0056] A pressing force is applied to the guide column 25, and the guide column 25 pushes the limiting column 23 to move toward one end of the limiting tube 22 through the fixing block 24. At the same time, the limiting column 23 pushes the conical block 28 to move toward one end of the limiting tube 22 through the fixing rod 27. After the conical block 28 is no longer in contact with the limiting ball 29, a pulling force is applied to the housing 26, so that the limiting tube 22 can be taken out from the movable frame 21 and the inside of the blade 163, thereby taking the old blade 163 out of the inside of the connecting tube 164;

[0057] When installing a new blade 163;

[0058] After the new blade 163 is placed in the connecting tube 164, a pressing force is applied to the guide column 25, and the guide column 25 pushes the limiting column 23 to move toward one end of the limiting tube 22 through the fixing block 24. At the same time, the limiting column 23 pushes the conical block 28 to move toward one end of the limiting tube 22 through the fixing rod 27. After the conical block 28 is no longer fitted with the limiting ball 29, the limiting tube 22 is inserted into the movable frame 21 and the blade 163, and the force applied to the guide column 25 is canceled. Under the elastic force of the first spring 241, the guide column 25 quickly returns to its original position, so that the conical block 28 moves toward the other end of the limiting tube 22. After the conical block 28 fits with the limiting ball 29, the limiting ball 29 fits with the outer surface of the movable frame 21.

[0059] This step makes the operation easier when replacing the blade 163, reduces the conflict between the wrench and other parts, and avoids the situation where the wrench accidentally damages other parts.

[0060] Embodiment 2

[0061] See also Figure 1 and Figure 4 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0062] The storage assembly also includes storage slots 32 opened inside the two sides of the limiting frame 31, a fixed pipe 33 fixed inside the middle end of the limiting frame 31, and a movable pipe 35 movably connected to the outer surface of the fixed pipe 33;

[0063] The storage slot 32 is used to store the blade 163, and the fixed tube 33 is used to receive and install the movable tube 35. The movable tube 35 can slide on the fixed tube 33 to adjust the distance between the limit plate 36 and the limit frame 31.

[0064] A second spring 34 is fixed to the inner surface of the fixed tube 33, and the other end of the second spring 34 is in contact with the inner surface of the movable tube 35. A limit plate 36 is fixed to the outer surface of the movable tube 35, and baffles 37 are fixed to the left and right surfaces of the limit plate 36.

[0065] Under the elastic force of the second spring 34, the movable tube 35 can be pulled. When the force applied to the movable tube 35 is removed, the movable tube 35 can quickly return to its original position. The limit plate 36 and the baffle 37 are provided to limit the blade 163 so that the blade 163 is stuck in the limit frame 31.

[0066] Working principle:

[0067] When storing the blade 163;

[0068] Under the elastic force of the second spring 34, a pulling force is applied to the limit plate 36, so that the movable tube 35 moves backward on the surface of the fixed tube 33, and the distance between the limit plate 36 and the limit frame 31 is increased. After the blade 163 is placed inside the storage slot 32, the force applied to the limit plate 36 is removed, and the limit plate 36 can quickly rebound to its original position;

[0069] When removing the blade 163;

[0070] A pulling force is applied to the limit plate 36. Under the elastic force of the second spring 34, the limit plate 36 is pulled to a certain distance, and the blade 163 can be taken out from the storage slot 32.

[0071] This step prevents the blade 163 from falling off the equipment and endangering the health of workers.
