[0050] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0051] Example 1

[0052] like Figure 1-5As shown, a wire cutting device proposed in this embodiment includes: a bottom box 1, a fixed plate 11 is vertically arranged on the bottom box 1; an axle 2, fixed on the fixed plate 11, and a wire wheel 21 is installed on the axle 2; a winding device 3, rotatably arranged on the fixed plate 11, the wire end of the wire wheel 21 is fixed on the winding device 3, and the winding device 3 rotates to wind the wire; a wire loading device 4, fixed on the fixed plate 11, the wire loading device 4 moves the wire on the winding device 3 to the wire taking device 5; the wire taking device 5, fixed on the bottom box 1, grabs the wire moved by the wire loading device 4; a wire cutting device 6, fixed on the bottom box 1, located on one side of the wire taking device 5, the wire loading device 4 moves the wire on the winding device 3 to the wire taking device 5, and the wire cutting device 6 cuts the wire; a controller 7, which is electrically connected to the winding device 3, the wire loading device 4 and the wire cutting device 6, and controls the operation of each electrically connected device to complete the wire cutting process.

[0053] In the above scheme, the line is a flexible line, which can be a cotton line, a silk line, a fiber line, etc. The axle 2 is fixed on the fixed plate 11 through a bearing, and a wire wheel 21 can be installed at one end of the axle 2. After the wire wheel 21 is installed, the wire wheel 21 is fixed by a handle, and the wire wheel 21 can be rotated on the axle 2 to release the line. A damping wheel 111 is installed at one end of the axle 2, and the wire wheel 21 is installed on the damping wheel 111. The other end of the axle 2 is located on the other side of the fixed plate 11, and a damper 112 is installed at the other end of the axle 2. By adjusting the damper 112, the friction resistance of the wire wheel 21 when rotating can be adjusted.

[0054] Then, the thread end on the wire wheel 21 is fixed on the winding device 3. After the controller 7 controls the winding device 3 to rotate to a predetermined angle, the wire loading device 4 is controlled to clamp the wire on the winding device 3 and move it to the wire taking device 5. The wire taking device 5 grabs and fixes the wire.

[0055] Finally, the controller 7 controls the wire cutting device 6 to cut the wire, so that the wire taking device 5 can be taken away, and the wire loading device 4 and the wire cutting device 6 are controlled to reset, thus completing a wire cutting process.

[0056] By repeating the above process, you can cut multiple equally spaced lines.

[0057] The axes of the wire loading device 4, the wire, the wire taking device 5 and the wire cutting device 6 are in one plane. The controller is a PLC controller, which can be arranged in the bottom box or outside the whole device (for example, a power distribution room outside the factory, or an office).

[0058] Through the above solution, the entire wire cutting process does not require human intervention, the length error between each equally spaced wire segment is small, the wire cutting accuracy can be improved, and the working speed can also be effectively improved.

[0059] In a specific embodiment, the wire winding device 3 includes: a wire winding assembly 31 and a rotating motor 32; the wire winding assembly 31 is connected to the output shaft of the rotating motor 32, and is respectively arranged on both sides of the fixed plate 11, and the rotating motor 32 is electrically connected to the controller 7 to fix the wire end of the wire wheel 21 on the wire winding assembly 31, and the controller 7 controls the rotating motor 32 to drive the wire winding assembly 31 to rotate a predetermined angle.

[0060] In the above scheme, the winding assembly 31 and the axle 2 are arranged on the same side of the fixed plate 11. After the wire end is fixed on the winding assembly 31, the controller 7 controls the rotating motor 32 to rotate a predetermined angle, wherein the predetermined angle can be set according to the length of the wire required by the user.

[0061] In addition, when the controller 7 controls the wire loading device 4 to move the wire to the wire taking device 5, the wire end will fall off the wire winding assembly 31 under the thrust of the wire loading device 4, and when the wire cutting device 6 cuts it, a new wire end will be formed and fixed on the wire winding assembly 31.

[0062] In a specific embodiment, the winding assembly 31 includes: a winding drum 311, a pressure plate 312 and a rubber pad 313; the winding drum 311 includes a winding shaft and a plurality of prisms, the winding shaft is connected to the output shaft of the rotating motor 32, and the prisms are evenly fixed on the winding shaft; the pressure plate 312 is fixed to the top of the prism; the rubber pad 313 is arranged between the pressure plate 312 and the prism, and the thread end of the reel 21 is fixed in the rubber pad 313.

[0063] In the above scheme, the prism and the winding shaft are integrally formed, and the number of prisms is at least three. The thread end of the wire wheel 21 is fixed in the rubber pad 313 of the nearest prism, so that the friction of the rubber pad 313 will fix the thread end, and then the wire is wound on the top of the prism driven by the rotating motor 32. When the winding rotates, the wire will be squeezed into the rubber pad 313 on each prism due to the tension generated by the rotation. When the winding shaft rotates by a predetermined angle, the rotating motor 32 stops working, and the wire loading device 4 will carry the wire and push the wire to the wire taking device 5. At this time, the thread end will fall off the rubber pad 313. When the wire cutting device 6 cuts the wire, a new thread end will be formed. The new thread end is squeezed into the rubber pad 313 on the next prism, so that when the wire loading device 4 and the wire cutting device 6 are reset, the next round of wire cutting operation can be performed.

[0064] This process is repeated until the number of equally spaced lines required by the user is reached.

[0065] In a specific embodiment, the wire loading device 4 includes: a telescopic drive 41 and two wire loading forks 42; the telescopic drive 41 is electrically connected to the controller 7 and fixed on the fixed plate 11, and two piston rods are provided on the telescopic drive 41, and a connecting plate is provided on the two piston rods, and the two wire loading forks 42 are fixed on the connecting plate.

[0066] In the above scheme, the telescopic drive 41 uses a double-axis cylinder, the cylinder part is fixed by screws on the other side of the fixed plate 11, the two piston rods pass through the holes on the fixed plate 11 and are connected to the connecting plate, and the two wire forks 42 are fixed on the connecting plate.

[0067] The two wire loading forks 42 are "Y"-shaped forks. When the winding device 3 rotates to the corresponding predetermined angle, the cylinder is started to drag the two "Y"-shaped forks through the two piston rods, forking the wire between the two prisms and pushing it to the wire taking device 5. At this time, the wire ends will fall off the rubber pads 313 of the prisms. Then the wire is cut according to the above-described process.

[0068] Through the above solution, the wire loading device 4 can push the wire to the wire taking device 5 more accurately.

[0069] In a specific embodiment, the wire taking device 5 includes: a support frame 51, a wire taking body 52 and a clamp 53. The support frame 51 is fixed on the bottom box 1, the wire taking body 52 is arranged on the support frame 51, and the clamp 53 is arranged on one side of the wire taking body 52 close to the wire loading device 4.

[0070] In the above scheme, the wire taking body 52 is a wire taking box, which is circular, and the support frame 51 includes at least three supporting feet, which are fixed on the bottom box 1. When the controller 7 controls the wire loading device 4 to push the wire winding device 3 onto the clamping claw 53 of the wire taking box, the clamping claw 53 will clamp the wire. Then the controller 7 controls the wire cutting device 6 to cut the wire between the clamping claw 53 and the wire winding device 3. In this way, the wire taking box will carry a predetermined length of wire, and the wire taking box can be taken away by other grabbing equipment.

[0071] In a specific embodiment, the wire cutting device 6 is a pneumatic scissors, which is electrically connected to the controller 7; the pneumatic scissors is fixed on the bottom box 1, and the controller 7 controls the wire loading device 4 to move the wire on the wire winding device 3 to the wire taking device 5, and the pneumatic scissors clamps the wire and controls the pneumatic scissors to close and cut the wire.

[0072] In the above scheme, a displacement drive can also be installed under the pneumatic scissors. The displacement drive can be a telescopic cylinder, which can move the pneumatic scissors. The controller 7 controls the wire loading device 4 to move the wire on the wire winding device 3 to the wire taking device 5. The controller 7 controls the displacement drive to start and drive the pneumatic scissors to the bottom of the wire between the clamp 53 and the wire winding device 3, and then controls the pneumatic scissors to close and cut the wire.

[0073] Through the above scheme, the thread cutting process can be automatically realized without manual operation, which is convenient and fast.

[0074] In a specific embodiment, the wire cutting device also includes: a line measuring sensor 22 and an alarm 8 electrically connected to the controller 7; the line measuring sensor 22 is arranged on the wheel axle 2, and the line measuring sensor 22 detects the rotation of the wire wheel 21. If it is detected that the wire wheel 21 does not rotate, a non-rotation signal is sent to the controller 7; when the controller 7 receives the non-rotation signal sent by the line measuring sensor 22, it controls the alarm 8 to start the alarm.

[0075] In the above scheme, the line measuring sensor 22 is an encoder, which can detect the rotation of the wire wheel 21 on the wheel shaft 2. If the wire wheel 21 does not rotate, it proves that the wire wheel 21 is stuck or there is no wire on the wire wheel 21. At this time, an alarm needs to be issued in the above manner to remind the user to check. If there is no wire, the wire wheel 21 is replaced. If the wire wheel 21 is stuck, the wire wheel 21 is adjusted or repaired.

[0076] In a specific embodiment, the thread cutting device further includes: a damping wheel 111 and a damper 112 . The damping wheel 111 is connected to the damper 112 and is respectively disposed on two sides of the fixing plate 11 .

[0077] In the above scheme, after the thread end is taken off the reel 21, it is first wound around the damping wheel 111 and then fixed on the winding device 3. The friction resistance of the damping wheel 111 during rotation can be adjusted by the damper 112. The damping wheel 111, the wheel shaft 2 and the winding assembly 31 are all arranged on the same side of the fixing plate 11.

[0078] Through the above scheme, the tension of the wire can be increased during the rotation of the winding device 3, so that the wire is always in a taut state and will not loosen, thereby avoiding the uneven length of the wire cut due to the loosening of the wire.

[0079] In a specific embodiment, guide rings 113 are provided on both sides of the damping wheel 111, and the guide rings 113 are fixed on the fixing plate 11. The guide rings 113 are used to guide the direction of the wire to avoid the deviation of the wire position during the wiring process.

[0080] In a specific embodiment, the wire cutting device further comprises a housing 9, which is fixed on the bottom box 1, and an opening is provided on the housing 9 at a position corresponding to the wire taking device 5. The housing 9 is used to protect the internal axle 2, the wire winding device 3, the wire loading device 4 and the wire cutting device 6, and has a dustproof effect. In addition, in order to facilitate the wire taking device 5 to take the wire, a corresponding opening is provided at the corresponding position, so that the wire taking device 5 carrying the wire can be taken off.

[0081] Through the above scheme of this embodiment, the user installs the wire wheel 21 on the axle 2 and fixes the wire end on the wire wheel 21 on the winding device 3. Then, the controller 7 controls the winding device 3 to rotate to a predetermined angle, controls the wire loading device 4 to clamp the wire on the winding device 3 and move it to the wire taking device 5. The wire taking device 5 grabs and fixes the wire, and the controller 7 controls the wire cutting device 6 to cut the wire. Then, the controller 7 controls the wire loading device 4 and the wire cutting device 6 to reset, completing the wire cutting process once, and repeating the above process, it can cut multiple equally spaced wires. In this way, the entire wire cutting process does not require manual participation, and the length error between each equally spaced wire is small, which can improve the wire cutting accuracy and effectively improve the working speed.

[0082] Example 2

[0083] The thread used in this embodiment is cotton thread.

[0084] The center of the winding assembly 31 is provided with an axial hole, which is connected to the shaft of the rotating motor 32. The winding assembly 31 is fixed to one side of the fixing plate 11 by bolt connection. The rotating motor 32 is fixed to the other side of the fixing plate 11 by a flange and bolts.

[0085] The structure of the winding assembly 31 is as follows: Figure 3 As shown, the prisms of the winding drum 311 are evenly distributed around the center of the winding shaft, and the pressure plate 312 presses the rubber pad 313 in the middle through the bolts, and the contact surface of the rubber pad 313, the winding drum 311 and the pressure plate 312 are glued together. The pressure of the pressure plate 312 on the rubber pad 313 can be adjusted by adjusting the bolts, and the friction of the cotton thread on the rubber pad 313 can also be adjusted.

[0086] like Figure 2 As shown, the damping wheel 111 is connected to the fixed plate 11 through an axis, cotton thread is wound on the damping wheel 111, and a damper 112 is installed on the other side where the damping wheel 111 is connected to the fixed plate 11. By adjusting the damper 112, the friction force of the damping wheel 111 during rotation can be adjusted.

[0087] like Figure 4 As shown, guide rings 113 are respectively arranged on both sides of the damping rotating wheel 111, and the guide rings 113 are fixed on the fixing plate 11 through shafts and bolts. The cotton thread passes through the guide rings 113, and the guide rings 113 can guide the cotton thread.

[0088] The line wheel 21 is connected to the fixed plate 11 through a shaft and a bearing, and a damper is installed at the other end of the shaft, and the extended end of the shaft of the damper 112 is connected to the encoder (i.e., the line sensor 22). The friction force when the line wheel 21 rotates can also be adjusted by adjusting the damper.

[0089] The encoder is used to detect whether the wire wheel 21 is rotating. When the wire wheel 21 rotates, the encoder detects the signal and transmits it to the PLC controller 7, which can send the signal to the alarm 8, so that people can observe that the wire cutting device is working. When the rotating motor 32 is working and the encoder does not detect the rotation signal of the wire wheel 21, the PLC controller 7 sends a fault signal line short or line is used up to the alarm 8, prompting people to check the cause of the fault.

[0090] The pneumatic scissors are composed of two parts: scissors and air claws. The air claws are fixed to the bottom box 1 by screws. The wire loading device 4 is composed of a double-axis cylinder and two "Y"-shaped forks. The two "Y"-shaped forks are fixed to the connecting plate of the piston rod of the double-axis cylinder. The double-axis cylinder and the "Y"-shaped fork pass through the hole of the fixing plate 11 and are connected to the fixing plate 11 by screws.

[0091] The support frame 51 is fixed on the bottom box 1 by screws, and the wire taking body 52 is placed on the support frame 51 .

[0092] The axes of the thread loading device 4, the cotton thread, the thread taking body 52 and the pneumatic scissors are in the same plane.

[0093] Description of working process:

[0094] 1. After the wire wheel 21 is installed in place, it is quickly fixed with a handle. The cotton thread passes through the guide ring 113, the damping wheel 111 and the winding assembly 31 respectively to complete the preparation work.

[0095] 2. The rotating motor 32 rotates a certain angle, and the cotton thread and the thread loading device 4 stop rotating after being in the plane. Because the thread wheel 21 and the damping wheel 111 are both equipped with the damping wheel 111, the two can stop rotating.

[0096] 3. Start the cylinder of the thread loading device 4, and the thread loading device 4 pushes the cotton thread onto the thread taking device 5. Because the cotton thread is squeezed on the rubber pad 313 of the winding assembly 31, each rubber pad 313 will exert pressure on it, and the thread wheel 21 and the damping wheel 111 are both equipped with damping wheels, one side of the free end of the cotton thread will definitely fall off.

[0097] 4. Start the pneumatic scissors and cut the other end of the cotton thread to make it the next free end.

[0098] 5. The wire loading device 4 and the pneumatic scissors are reset, and the wire taking body 52 is removed, completing a wire cutting operation.

[0099] Repeat steps 2 to 5 above to achieve continuous and evenly spaced thread trimming.

[0100] In summary, the entire wire cutting process does not require human intervention, and the length error between each equally spaced wire segment is small, which can improve the wire cutting accuracy and effectively improve the working speed.
