[0075] Specifically, a first movable bracket 121 is fixedly connected to the sliding end of the first linear module 12, and a first linear member 123 is fixedly connected and a slidingly matched cutter 122 is provided on the first movable bracket 121. The telescopic end of the first linear member 123 is fixedly connected to the cutter 122.

[0076] A second straight member 141 is provided below both ends of the bead 14. The telescopic end of the second straight member 141 is fixedly connected to the bead 14. The second straight member 141 pushes the bead 14 to move up and down. When the bead 14 descends to the lowest end, the bead 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 with the front end of the fabric laid above the grabbing groove 131 .

[0078] Furthermore, a second linear module 2 is provided inside the bottom bracket 1. There are two sets of the second linear modules 2, which are symmetrically arranged inside the bottom bracket 1. The second linear modules 2 are driven by a drive shaft 22. The first motor 111 drives the drive 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. A first air gripper 24 is provided above the third movable bracket 21. There are multiple sets of first air grippers 24, the number of which is the same as the number of gripping slots 131. When the third movable bracket 21 moves, it drives the third movable bracket 21 and the first air grippers 24 to move synchronously.

[0080] A third linear member 231 is provided between the third movable bracket 21 and the driving shaft 22. A fourth movable bracket is fixedly connected to the telescopic end of the third linear member 231. The fourth movable bracket is fixedly provided with second air grippers 23 distributed in an array. The third linear 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 on 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. There are two groups of second pressing assemblies 33, 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. The fifth movable bracket 321 is provided with a rotating drive belt 322, a sliding movable plate 323, and a fixedly connected guide rod 325. The drive belt 322 is driven by a motor. The movable plate 323 has multiple groups and is slidably engaged with the fifth movable bracket 321 via a slide block.

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

[0084] The second pressing assembly 33 includes a sixth movable bracket 331, to which a fifth linear 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 linear member 332. The fifth linear 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 member 334 is provided on the side of the sixth movable bracket 331. The sixth straight member 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. The sixth straight member 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. The ultrasonic welding mechanism 41 includes a first connecting member 411. 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, and a second connecting member 412 that can be raised and lowered is provided on the outside of the first connecting member 411. A guide pin 4122 is provided at the top of the second connecting member 412, which is inserted into the sliding groove 4111 and slidably cooperates with it. First return members 413 are provided on both sides of the second connecting member 412, and a spring is sleeved on the outside of the first return member 413. One end of the first return member 413 is fixedly connected to the second connecting member 412, and the other end of the first return member 413 is fixedly connected to the first connecting member 411. When the second connecting member 412 is squeezed, the first return member 413 contracts, driving the second connecting member 412 to rise and fall.

[0088] Slots are provided on both sides of the bottom end of the second connecting member 412, and a push plate 414 rotatably connected and a stopper 4121 fixedly connected are provided in the slots. A second reset member 4141 is provided at the rotation point between the push plate 414 and the second connecting member 412, and 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 provided below 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 it can meet the requirements that when the second connecting member 412 moves downward, the two push wheels 4142 can contact the top of the corresponding cloth, 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 tightened.

[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 optionally provided on the outside of the push wheel 4142, or the push wheel 4142 can be prepared using a material with greater friction, etc. It is only necessary to increase the friction at the contact position between the push wheel 4142 and the cloth to avoid slipping.

[0092] In the above technical solution, the push plate 414 is set 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 tensioning failure.

[0094] Furthermore, a sliding supporting plate 6 and a lifting plate 7 are provided inside the bottom bracket 1, and a lifting drive 8 is provided under the lifting plate 7. The supporting 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 of drive slots 64 are 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. 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 into 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. 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 part of the transmission bar 83 is raised. 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 described in the embodiments of this 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 tensioning shaft and between the support plate 13 and the pressure strip 14. The fabric is placed on the support plate 13, and the front end of the fabric is placed above the grabbing groove 131;

[0101] The first motor 111 starts to drive the second linear module 2 to operate, and the second linear module 2 drives the third movable bracket 21 and the first air claw 24 to approach the first bracket 11. 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. Then the third movable bracket 21 and the first air claw 24 retreat and 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 bar 14 down to press the fabric against the support plate 13, and then the first linear member 123 pushes the cutter 122 down, 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, as shown in FIG. 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 retracts the second air claw 23 and the first air claw 24 to 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 member 326 starts to push the first pressing wheel 327 down to press the first layer of fabric. 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.

[0105] Then the heating wire wiring machine 5 is started to perform the heating wire wiring operation, and the heating wire is wrapped around the lead needle 73 for 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 the 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 advance a distance between the lead needles 73, the ultrasonic welding mechanism 41 descends and welds until the welding is completed. At this time, the welding of the first group of electric blanket fur parts is 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, and the lead needle 73 descends and is extracted from the electric blanket hair piece. Then the electric blanket hair piece is taken away by a robot or manually.

[0108] In the above technical solution, the third module drives the transmission bar 83 and the telescopic member 82 to move, and the lifting plate 7 is connected 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, a clearance hole for the transmission bar 83 needs to be opened on one side of the lifting plate 7. 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. The above embodiments and descriptions are merely illustrative of the principles of the present application. Various changes and improvements may be made to the present application without departing from the spirit and scope of the present application, and such changes and improvements fall within the scope of the present application.
