[0076] A second straight member 141 is provided below both ends of the pressure strip 14. The telescopic end of the second straight member 141 is fixedly connected to the pressure strip 14. The second straight member 141 pushes the pressure strip 14 to move up and down. When the pressure strip 14 descends to the lowest end, the pressure strip 14 presses on the support plate 13.

[0077] One end of the support plate 13 is provided with a through grabbing groove 131 . The material roll 15 passes through the support plate 13 and the pressure strip 14 after passing around the tensioning shaft. The fabric is placed on the support plate 13 , and the front end of the fabric is laid above the grabbing groove 131 .

[0078] Furthermore, a second linear module 2 is provided inside the bottom bracket 1. The second linear module 2 has two groups, which are symmetrically arranged inside the bottom bracket 1. The second linear module 2 is driven by a driving shaft 22. The first motor 111 drives the driving shaft 22 to rotate synchronously through a synchronous pulley and a synchronous belt.

[0079] A third movable bracket 21 is provided at the sliding end of the second linear module 2, and a first air gripper 24 is provided above the third movable bracket 21. There are multiple groups of the first air grippers 24, and the number is the same as the grabbing grooves 131. When the third movable bracket 21 moves, it drives the third movable bracket 21 and the first air gripper 24 to move synchronously;

[0080] A third straight member 231 is provided between the third movable bracket 21 and the driving shaft 22, and a fourth movable bracket is fixedly connected at the telescopic end of the third straight member 231. The fourth movable bracket is fixedly provided with second air grippers 23 distributed in an array, and the third straight member 231 drives the second air grippers 23 and the first air grippers 24 to move toward each other.

[0081] Furthermore, a second movable bracket 31 is fixedly connected at the movable end of the pressing assembly 3, a first pressing assembly 32 is fixedly connected at the side of the second movable bracket 31, and a second pressing assembly 33 is fixedly connected at the lower end of the second movable bracket 31. The second pressing assembly 33 has two groups, which are symmetrically arranged at both ends of the first pressing assembly 32.

[0082] Specifically, the first pressing assembly 32 includes a fifth movable bracket 321, which is fixedly connected to the second movable bracket 31, and is provided with a rotating driving belt 322, a slidingly matched moving plate 323 and a fixedly connected guide rod 325 on the fifth movable bracket 321, the driving belt 322 is driven by a motor, and the moving plate 323 has multiple groups and is slidably matched with the fifth movable bracket 321 through a slide rail slider;

[0083] The movable plates 323 are each provided with a fixedly connected fourth straight member 326, and a first pressure wheel 327 is provided at the telescopic end of the fourth straight member 326. The fourth straight member 326 pushes the first pressure wheel 327 to rise and fall, and the movable plates 323 are connected by a cross rod 324. The connection point of the cross rod 324 at the center of the cross rod 324 slides with the guide rod 325. The movable plates 323 at both ends are fixedly connected with the driving belt 322. When the driving belt 322 rotates, the movable plates 323 are driven to move synchronously, thereby changing the spacing between the movable plates 323, the fourth straight member 326 and the first pressure wheel 327.

[0084] The second pressing assembly 33 includes a sixth movable bracket 331, on which a fifth straight member 332 is fixedly connected, a second pressing wheel 335 is rotatably connected to the side of the sixth movable bracket 331, and a third pressing wheel 333 is provided at the telescopic end of the fifth straight member 332. The fifth straight member 332 can drive the third pressing wheel 333 to adjust its height, thereby changing the distance between the third pressing wheel 333 and the second pressing wheel 335;

[0085] A sixth straight piece 334 is provided on the side of the sixth movable bracket 331, and the sixth straight piece 334 is fixedly connected to the second movable bracket 31. The sixth movable bracket 331 slides with the second movable bracket 31 through a slide rail slider, and the sixth straight piece 334 pulls the sixth movable bracket 331 towards and away from the first pressing assembly 32.

[0086] Furthermore, a fixedly connected ultrasonic welding mechanism 41 is provided at the lifting end of the welding assembly 4, and the ultrasonic welding mechanism 41 includes a first connecting member 411, and the first connecting member 411 is fixedly connected to the lifting end of the welding assembly 4;

[0087] Specifically, a sliding groove 4111 is provided inside the first connecting member 411, a second connecting member 412 which can be raised and lowered is provided on the outside of the first connecting member 411, a guide pin 4122 is provided on the top of the second connecting member 412, the guide pin 4122 is inserted into the sliding groove 4111 and slidably cooperates with the sliding groove 4111, first reset members 413 are provided on both sides of the second connecting member 412, a spring is sleeved on the outside of the first reset member 413, one end of the first reset member 413 is fixedly connected to the second connecting member 412, and the other end of the first reset member 413 is fixedly connected to the first connecting member 411, when the second connecting member 412 is squeezed, the first reset member 413 contracts, driving the second connecting member 412 to be raised and lowered;

[0088] Both sides of the bottom end of the second connecting member 412 are provided with grooves, in which a rotatably connected push plate 414 and a fixedly connected stopper 4121 are provided. A second reset member 4141 is provided at the rotation point between the push plate 414 and the second connecting member 412. The second reset member 4141 drives the push plate 414 to approach the contact stopper 4121. A push wheel 4142 is provided at the lower end of the push plate 414, and a welding head 415 is provided below the second connecting member 412.

[0089] It is understandable that multiple welding heads 415 may be arranged under the same second connecting member 412 .

[0090] It can be understood that the push wheel 4142 can be rotatably arranged under the corresponding push plate 414, or it can be fixedly arranged under the corresponding push plate 414, as long as the two push wheels 4142 can contact the top of the corresponding cloth when the second connecting member 412 moves downward, and as the second connecting member 412 further descends, the two push wheels 4142 can move away from each other so that the part of the cloth in contact with the two can be tensioned.

[0091] In some technical solutions, in order to avoid slipping between the push wheel 4142 and the corresponding cloth, a damping surface is provided at the contact position between the push wheel 4142 and the cloth. The damping surface is the side with greater friction. An anti-slip strip can be provided on the outside of the push wheel 4142, or the push wheel 4142 can be prepared using a material with greater friction. It is only necessary to increase the friction between the push wheel 4142 and the cloth to avoid slipping.

[0092] In the above technical solution, the push plate 414 is arranged at the bottom end of the second connecting member 412 at a first predetermined angle, wherein the first predetermined angle is an angle greater than 90°. This setting is mainly to enable the two push wheels 4142 to be driven away from each other to tension the fabric when the second connecting member 412 drives the push plate 414 to descend.

[0093] The purpose of setting the stopper 4121 is to enable the push plate 414 to maintain the first predetermined angle when it is restored under the drive of the second restoration member 4141, so as to avoid excessive restoration so that the angle is less than 90°, which causes tension failure.

[0094] Furthermore, a sliding support plate 6 and a lifting plate 7 are provided inside the bottom bracket 1, and a lifting drive 8 is provided below the lifting plate 7. The support plate 6 moves longitudinally along the bottom bracket 1, and the moving direction is the same as the moving direction of the third movable bracket 21.

[0095] Specifically, a supporting surface 61 is provided at one end of the supporting plate 6 , a penetrating positioning hole 62 and a hollow groove 63 are provided inside the supporting plate 6 , and an array-distributed driving slot 64 is provided at the lower end of the supporting plate 6 .

[0096] Both sides of the lifting plate 7 are provided with inwardly recessed grooves 71, and the lifting plate 7 is provided with array-distributed positioning grooves 72, lead pins 73 and positioning posts 74, and the second pressing assembly 33 moves in the inwardly recessed grooves 71;

[0097] When the lifting plate 7 rises to the highest point, the supporting plate 6 is dragged in the positioning groove 72 , and the positioning column 74 passes through the positioning hole 62 to lock the lifting plate 7 and the supporting plate 6 , and the lead pin 73 is higher than the supporting plate 6 .

[0098] The lifting drive 8 is fixed in the bottom bracket 1, and the lifting drive 8 includes a third linear module 81. A rotating transmission bar 83 and a fixedly connected telescopic member 82 are provided at the top of the third linear module 81. The transmission bar 83 is driven by a motor and a sprocket. The middle of the transmission bar 83 is convex, and a driving card 84 is arranged on the transmission bar 83. After the third linear module 81 is raised, the lifting plate 7 is driven to rise synchronously. After the lifting plate 7 contacts the supporting plate 6, the telescopic member 82 is compressed and shortened in length. Then the highest driving card 84 is stuck in the driving card slot 64. When the transmission bar 83 rotates, it drives the supporting plate 6 and the lifting plate 7 to move longitudinally at the same time.

[0099] The working principle of the electric blanket ultrasonic welding mechanism and the fully automatic composite equipment recorded in the embodiments of the present application is as follows:

[0100] When in use, the first layer of the electric blanket is cut first, and the material roll 15 passes through the support plate 13 and the pressure strip 14 after passing through the tensioning shaft, and the material is placed on the support plate 13, and the front end of the material is placed above the grabbing groove 131;

[0101] The first motor 111 starts to drive the second linear module 2 to run, and the second linear module 2 drives the third movable bracket 21 and the first air claw 24 to approach the first bracket 11, and the movable end of the first air claw 24 is inserted into the grabbing groove 131, and then the movable end of the first air claw 24 is closed to clamp the front end of the fabric, and then the third movable bracket 21 and the first air claw 24 retreat to pull the fabric out to above the supporting plate 6. After reaching the required fabric length, the third movable bracket 21 and the first air claw 24 stop.

[0102] The second linear member 141 pulls the pressure strip 14 downward to press the fabric against the support plate 13, and then the first linear member 123 pushes the cutter 122 downward, and then the first linear module 12 drives the cutter 122 to move and cut the fabric, and then the third movable bracket 21 and the first air claw 24 pull the cut fabric to continue for a distance, and the tail end of the cut fabric rests on the supporting surface 61, and the tail end is exposed from the high end of the supporting surface 61, such as Figure 5 As shown, the third straight member 231 drives the second air claw 23 to approach the supporting surface 61, and the second air claw 23 clamps the tail end of the fabric. Then, the third straight member 231 moves back and the second air claw 23 and the first air claw 24 straighten the fabric.

[0103] The sixth straight line member 334 pulls the sixth movable bracket 331 close to the supporting plate 6, and the third pressure wheel 333 and the second pressure wheel 335 are respectively arranged on the upper and lower surfaces of the edge of the fabric, and then the fifth straight line member 332 pushes the third pressure wheel 333 to descend, and the third pressure wheel 333 and the second pressure wheel 335 clamp the fabric, and the lifting drive 8 is started, and the third linear module 81 pushes the lifting plate 7 to rise. After the lifting plate 7 contacts the supporting plate 6, the telescopic member 82 is compressed and shortened in length, and then the highest driving card 84 is stuck in the driving card slot 64.

[0104] The first pressing wheel 327 is adjusted according to the width of the fabric, and the driving belt 322 rotates to drive the movable plate 323 to adjust to the specified spacing and total width. The first pressing wheel 327 needs to avoid the guide needle 73, and then the fourth straight line member 326 starts to push the first pressing wheel 327 down to press the first layer of fabric, and the pressing assembly 3 starts to drive the first pressing assembly 32 and the second pressing assembly 33 to start moving away from the first bracket 11. The first pressing assembly 32 and the second pressing assembly 33 press the first layer of fabric on the lifting plate 7, and the guide needle 73 passes through the first layer of fabric. After the pressing assembly 3 drives the first pressing assembly 32 and the second pressing assembly 33 to completely press the first layer of fabric on the lifting plate 7 and the supporting plate 6, the first pressing assembly 32 and the second pressing assembly 33 retreat and leave.

[0105] Then the heating wire wiring machine 5 is started to perform the heating wire wiring operation. The heating wire wraps around the lead needle 73 for surrounding wiring. The wiring of the heating wire wiring machine 5 is a common existing technology and will not be described in detail here. Then repeat the above operation, cut off the second layer of fabric, press the second layer of fabric on the heating wire and the first layer of fabric, and pass the lead needle 73 through the second layer of fabric. Finally, prepare for ultrasonic welding operation.

[0106] The transmission bar 83 starts to rotate. When the transmission bar 83 rotates, it drives the supporting plate 6 and the lifting plate 7 to move longitudinally at the same time. The welding assembly 4 drives the ultrasonic welding mechanism 41 to descend. The push wheel 4142 first contacts the edge of the welding point. As the second connecting member 412 continues to descend, the push wheel 4142 rolls to further flatten the welding point, and then the welding head 415 contacts the fabric for welding. Each time the supporting plate 6 and the lifting plate 7 move forward a distance of the lead needle 73 spacing, the ultrasonic welding mechanism 41 descends and welds once until the welding is completed. At this time, the welding and compounding of the first group of electric blanket wool parts are completed.

[0107] Then the supporting plate 6 and the lifting plate 7 move back to their original positions and return to the bottom bracket 1, the lifting drive 8 drives the lifting plate 7 to descend, the lead needle 73 descends and is pulled out from the electric blanket wool piece, and then the electric blanket wool piece is taken away by a robot or manually.

[0108] In the above technical scheme, the third module drives the transmission bar 83 and the telescopic member 82 to move, and connects the lifting plate 7 to one side of the telescopic member 82. In this way, when the third linear module 81 drives the transmission bar 83 and the telescopic member 82 to move upward so that the lifting plate 7 is attached to the bottom end of the supporting plate 6, the positioning pin at the top of the lifting plate 7 can pass through the fabric on the supporting plate 6; then threading and laying of the second layer of fabric are performed. When the second layer of fabric is laid and ultrasonic welding is required, the telescopic member 82 drives the lifting plate 7 to move downward for a distance so that the lifting plate 7 is separated from the supporting plate 6. At this time, the driving card 84 is still engaged in the driving card slot 64. When the transmission bar 83 is transmitted, the fabric to be welded can be driven by the supporting plate 6 to pass through the welding assembly 4 for welding.

[0109] It is understandable that in this technical solution, it is necessary to open a circumvention hole on one side of the lifting plate 7 to circumvent the transmission bar 83. The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, and these changes and improvements fall within the scope of the present application to be protected.
