Description

Technical Field

[0001] The utility model relates to the technical field of electric blanket wiring, specifically to a wiring machine for precision electric blanket heating wires. Background Art

[0002] The heating wire structure inside the electric blanket includes an inner layer of heating wire and an outer layer of conductive copper wire, which are insulated by a thermal sensitive material in the middle. As a contact type electric heating appliance, the internal structure of the electric blanket involves the arrangement of electric heating elements and protection mechanisms. In the design of the electric blanket, the heating wire usually adopts a double-layer structure, where the inner layer is the heating wire and the outer layer is the conductive copper wire. This double-layer structure not only helps the heating function of the electric blanket, but also realizes the insulation between the heating wire and the outer conductive copper wire through the thermal sensitive material. When the temperature of the inner layer is too high, the thermal sensitive material will melt, causing the heating wire to be short-circuited with the outer conductive copper wire, and then triggering the fuse inside the temperature controller to melt, thus realizing the overheat protection function.

The wire controlling mechanism includes a wire guiding cylinder, a transverse wire controlling group and a longitudinal wire controlling group. The transverse wire controlling group includes a second slider, and the second slider is slidably arranged on the operating table; the longitudinal wire controlling group includes a connecting frame and a first slider, the connecting frame is fixedly arranged on the second slider, the first slider is slidably arranged on the connecting frame, and the first slider is connected to the wire guiding cylinder. However, this utility model can only perform the wiring of the heating wire for the electric blanket, and cannot perform the pressing process and the subsequent cooling and shaping after the wiring is completed. Many subsequent processes are still required, and at the same time, the conversion between different processes is needed, which reduces the work efficiency.

[0033] A wiring machine for the heating wire of a precision electric blanket, comprising a base 1, a box body 2 is arranged on the base 1, conveying devices 3 are arranged at both ends of the base 1 corresponding to the box body 2, a plurality of cover bodies 4 are evenly connected to the upper end of the box body 2, adsorption holes 5 are opened on the cover bodies 4, the adsorption holes 5 are all communicated with an air suction pipe 6, and the air suction pipe 6 is arranged in the box body 2; thus, the electric blanket material to be wired is conveyed to the cover body 4 through the conveying device 3, and the adsorption holes 5 on the cover body 4 generate suction force through the air suction pipe 6 to tightly attach the electric blanket material under the cover body 4, preventing deviation during the wiring process and ensuring that the material remains flat and wrinkle-free during the conveying process. Anti-slip lines 7 are opened on the cover body 4. The anti-slip lines 7 on the cover body 4 increase the friction force on the surface of the electric blanket material, further ensuring the stability of wiring.

[0034] A first gantry 8 and a second gantry 15 are slidably connected to the base 1, a wiring device 9 is connected to the first gantry 8, the wiring device 9 horizontally slides on the first gantry 8 through a sliding plate 10, and the wiring device 9 slides up and down on the sliding plate 10; a positioning plate 11 is arranged at the lower end of the wiring device 9, a wiring groove 12 is opened on the positioning plate 11, and the positioning plate 11 is connected to the first gantry 8. The positioning plate 11 is connected to the first gantry 8 through a connecting rod 13, and the first gantry 8 is provided with a kidney-shaped groove 14 corresponding to the connecting rod 13. Thus, the wiring device 9 adjusts through the sliding plate 10 and the connecting rod 13 on the first gantry 8 to realize horizontal and vertical sliding, and the wiring groove 12 on the positioning plate 11 is accurately aligned according to the designed path of the heating wire, ensuring that the heating wire can be arranged along the predetermined trajectory.

After the wiring of the electric blanket material is completed, the heating pipe 16 on the second gantry 15 heats the heating wire to make the heating wire better adhered and fixed to the material. Thus, the wired electric blanket material sequentially passes through the first support roller 18 and the second support roller 19, and then the cloth on the cloth roller 20 is rotated and laid on the wired electric blanket material.

[0036] Further, the cooling and shaping device includes a cooling table 24, above which a cold air blower 25 is arranged.

Then the electric blanket material enters the cooling and shaping device, and the cold air generated by the cold air blower 25 blows towards the electric blanket material, so that the electric blanket material cools down rapidly. Through cooling, the heating wire can be shaped to ensure that the heating wire does not shift during the use of the electric blanket. The heat dissipation holes 28 and the brackets 29 help the hot air to be discharged quickly, promote the heat exchange between the cold air and the electric blanket material, and thus accelerate the cooling process; the rotating wheels 30 reduce the friction between the electric blanket and the brackets 29 and protect the electric blanket material from damage. Furthermore, the conversion between processes and the material handling are reduced, the production efficiency is improved, the labor cost and production cost are reduced, and the overall quality of the product is improved.

The distance between the first friction roller 32 and the second friction roller 33 can be adjusted by rotating the first lead screw 35 according to the thickness of the electric blanket material. When the first lead screw 35 rotates, the first sliding block 34 rotatably connected to the first lead screw 35 drives the second friction roller 33 to move up and down, thereby changing the distance between the two rollers. The second friction driving device includes a second frame 36, on which a third friction roller 37 is rotatably connected. Above the third friction roller 37, a fourth friction roller 38 is arranged in parallel. The fourth friction roller 38 is connected to the second frame 36 through a second sliding block 39 for up and down sliding.

When the second lead screw 40 rotates, the first sliding block 34 rotatably connected to the second lead screw 40 drives the fourth friction roller 38 to move up and down, thereby changing the distance between the two rollers.

[0038] The working process of the present utility model is as follows:

[0039] First, the electric blanket material waiting to be wired is conveyed to the cover body 4 through the conveying device 3. The suction holes 5 on the cover body 4 generate suction force through the suction pipe 6 to tightly attach the electric blanket material under the cover body 4, preventing deviation during the wiring process. Furthermore, the wiring device 9 adjusts through the sliding plate 10 and the connecting rod 13 on the first gantry 8 to achieve lateral and longitudinal sliding. The wiring grooves 12 on the positioning plate 11 are accurately aligned according to the designed path of the heating wire to ensure that the heating wire can be arranged along the predetermined trajectory. The wiring device 9 accurately lays the heating wire at the designated position on the electric blanket material to form a predetermined circuit path, ensuring the accuracy of the heating wire wiring. After the wiring of the electric blanket material is completed, the heating tube 16 on the second gantry 15 heats the heating wire to better bond and fix the heating wire to the material. Furthermore, the wired electric blanket material passes through the first support roller 18 and the second support roller 19 in sequence, and then the fabric on the fabric roller 20 is rotated and laid on the wired electric blanket material. A return spring 23 is arranged between the third sliding block 21 and the sliding groove 22 to press the fabric roller 20, and then the first friction roller 32 and the second friction roller 33 start to rotate and drive the electric blanket material to move forward through friction. Furthermore, the electric blanket material enters the cooling and shaping device, and the cold air generated by the air cooler 25 blows towards the electric blanket material, and then the electric blanket material quickly cools down.
