Description

Technical Field

[0001] The present invention relates to the technical field of electric blanket production, and specifically relates to an automatic cloth laying device for electric blankets. Background Art

[0002] The manufacture of electric blankets generally requires several steps such as laying the first layer of cloth, winding the heating wire, laying the second layer of cloth on the heating wire, and welding. Currently, the electric blanket production machines on the market are all semi-automatic, requiring multiple people to operate the machines, which is rather troublesome and difficult to meet the needs of the staff. In addition, for the electric blankets produced by the existing technology, the heating wires inside are only fixed in the form of hot pressing. During subsequent use by the user, the wires are prone to looseness, resulting in subsequent winding of the heating wires inside the electric blanket, leading to a short lifespan of the electric blanket and difficulty in meeting the needs of the user.

[0032] To clearly describe the working principle of the present invention, we take Figure 1It is described from the azimuth perspective as follows: S1. Preparation work: Install the fabric roller 101 and the electric heating wire roller 501. Pass the fabric outlet end on the fabric roller 101 under the guiding roller 104. The output ends of the two groups of first air cylinders 105 extend to drive the pressing block 106 to move downward, press the fabric outlet end on the top of the mounting base 102, and let the electric heating wire outlet end on the electric heating wire roller 501 enter the interior of the fixed disk 514. The output ends of the two groups of sixth electric push rods 515 inside it extend to drive the two groups of pressing members 516 inside it to approach each other and fix the electric heating wire outlet end in the fixed disk 514; S2. Base fabric installation: The output end of the first stepping motor 204 drives the first lead screw 202 to rotate, so that the movable frame 205 moves to the left. The output end of the first air cylinder 105 retracts to drive the pressing block 106 to move upward. The fabric roller 101 feeds the fabric under the action of an external motor. The fabric outlet end passes between the two groups of clamping members 211. The output end of the first servo motor 210 drives the first threaded rod 208 to rotate, so that the two groups of clamping members 211 approach each other to clamp the fabric outlet end. Secondly, the output end of the first stepping motor 204 drives the first lead screw 202 to rotate in the reverse direction, so that the movable frame 205 moves to the right matching position of the table board 107. The output end of the third air cylinder 113 extends to drive the pressing plate 114 to move downward to press the fabric on the top of the table board 107. Then, under the adjustment of the output end of the first electric push rod 206, the fabric is in a taut state and spreads flat on the top of the table board 107; S3. Installation of the hook part of the Velcro 111: Under the combined action of the output ends of the third stepping motor 404, the fourth stepping motor 410, and the third electric push rod 413, the glue applicator head 415 moves in the horizontal, vertical, and longitudinal directions. The glue applicator head 415 applies glue at the preset points on the fabric. There are two groups of conveyors arranged outside the front side of the machine body 1. One group conveys the hook part of the Velcro 111, and the other group conveys the loop part of the Velcro. Under the action of the output end of the drive motor 406, the top frame 407 rotates, and then the vacuum suction plate 416 faces the outside of the front side of the machine body 1. The vacuum suction plate 416 sucks the hook part of the Velcro 111 at the end of the conveyor. Also under the combined action of the output ends of the third stepping motor 404, the fourth stepping motor 410, and the third electric push rod 413, the vacuum suction plate 416 moves in the horizontal, vertical, and longitudinal directions. The vacuum suction plate 416 sequentially installs the hook part of the Velcro 111 at the glue-applied positions on the fabric. And under the cooperation of the output end of the first stepping motor 204 and the output end of the second electric push rod 212, the hot pressing roller 214 performs hot pressing on the hook part of the Velcro 111, and the glue quickly solidifies, fixing the hook part of the Velcro 111 on the fabric. Then, the output end of the second cylinder 108 drives the mounting plate 109 and several groups of winding needles 110 to move upward as a whole. The winding needles 110 pass through the holes reserved in the machine body 1 and the table board 107 and pass through the fabric. One end of the fabric is squeezed by the pressing plate 114, and the other end is clamped by two groups of clamping members 211. And rubber pads are provided on the pressing plate 114 and the clamping members 211 to prevent deviation; S4. Arrangement of the heating wire: Under the action of the output ends of the fifth stepping motor 505, the sixth stepping motor 509, and the fifth electric push rod 511, the lifting plate 512 moves to the front side of the fixed plate 514. The central through holes of the lifting plate 512 and the fixed plate 514 are concentric. Under the action of an external motor, the heating wire roller 501 feeds the wire. At the same time, the two pressing members 516 inside the fixed plate 514 release the clamping of the heating wire, so that the discharging end of the heating wire enters the lifting plate 512. And then the lifting plate 512 moves in the horizontal, vertical, and longitudinal directions, and the discharging end of the heating wire is sequentially wound around the winding needles 110 in an "S" shape (as Figure 14 shown in the state); S5. Installation of the loop part of the Velcro: The vacuum suction plate 416 sucks the loop part of the Velcro at the end of the conveyor. Under the combined action of the output ends of the third stepping motor 404, the fourth stepping motor 410, and the third electric push rod 413, the vacuum suction plate 416 sequentially installs the loop part of the Velcro on the top of the hook part of the Velcro 111 to limit the wound heating wire and prevent it from deviating; S6. Cutting and Gluing: The two sets of cutting mechanisms 3 work synchronously to cut off the excess fabric at both ends of the fabric, so that the size of the fabric matches the size of the table board 107. The fabric roller 101 drives the fabric to retract under the action of an external motor, and the discharge end of the fabric returns to the state of preparation work in S1. Then, the glue applicator head 415 applies glue to the edge of the fabric on the table board 107. S7. Top Cloth Installation: Repeat the steps of S2. Another piece of fabric is pulled to directly above the fabric on the table board 107. Under the cooperation of the output end of the third cylinder 113 and the output end of the first electric push rod 206, the pulled fabric is pressed downward to bond with the fabric on the table board 107. Then, the output end of the second cylinder 108 drives the mounting plate 109 and several sets of winding needles 110 to move downward as a whole to reset. Under the cooperation of the output end of the first stepping motor 204 and the output end of the second electric push rod 212, the hot pressing roller 214 moves left and right to perform reciprocating hot pressing on the bonded fabric, so that the glue solidifies. S8. Wire Cutting: The output ends of the two sets of sixth electric push rods 515 in the fixed disk 514 extend, driving the two sets of pressing parts 516 inside to approach each other to clamp the heating wire. The output end of the second servo motor 520 drives the second threaded rod 518 to rotate, so that the two sets of blades 521 approach each other along the second fixed rod 519 to cut off the heating wire. The external manipulator grabs the produced electric blanket prototype to the next process for edge stitching. And the two heating wires located outside the electric blanket prototype are electrically connected to the electric blanket controller. At this time, the discharge end of the heating wire is still fixed in the fixed disk 514 and returns to the state of preparation work in S1. Just repeat the above steps to continuously produce electric blankets without the need for staff participation, which is convenient and fast. And by using the form of Velcro fixation inside the electric blanket, the heating wire will not become loose during the subsequent use of the electric blanket, which is more firm and improves the production quality of the new electric blanket. The present invention has a substantial improvement and is fully automated throughout the process, which is conducive to the promotion and use of this method.
