Description

Technical Field

[0001] The utility model relates to electric blanket production equipment, in particular to an electric blanket heating wire wiring device. Background Art

[0002] The electric blanket includes two layers of fabric and a heating wire arranged between the two layers of fabric. The heating wire needs to be arranged in a serpentine shape so that the entire electric blanket area has the heating wire. The existing electric blanket automatic processing equipment first reciprocates the heating wire on the plane of the first layer of fabric, and then stacks the second layer of fabric, and the two layers of fabric are bonded together to obtain the electric blanket. Among them, a hanging needle is needed to locate the heating wire in the process of reciprocating the heating wire, and its structure is relatively complicated. In order to replace the hanging needle, a new processing technology is proposed, in which the heating wire is arranged between two horizontal pressing rollers arranged in front and behind, and the two pressing rollers drive a layer of fabric to move respectively, and the heating wire is wired from the top of the gap between the two pressing rollers, and the heating wire is arranged between the two layers of fabric. After arranging a heating wire, the pressing roller rotates to drive the fabric to move, and the two layers of fabric sandwich the heating wire in the middle. After adopting the new process, the hanging needle is not required, which greatly simplifies the structure of the production equipment. However, a new heating wire wiring device is urgently needed to be suitable for the newly proposed electric blanket processing technology. Utility Model Content

[0024] At the same time, a wire crimping mechanism 6 and a wire end fixing mechanism 7 located in front of the wire crimping mechanism 6 are provided on the frame 1. The wire crimping mechanism 6 is used to fix the end of the electric heating wire 9 in the gap between the two laminating rollers 10. The wire end fixing mechanism 7 is used to fix the reserved wire end of the electric heating wire 9. A wiring member 5 is detachably provided on the slide seat 3. The wiring member 5 is used to place the electric heating wire 9 between the two laminating rollers 10.

[0025] A mounting frame 11 is fixedly connected to the slide seat, and the wiring component 5 can be directly installed on the mounting frame 11 of the slide seat 3. Under this structure, the height of the wiring component 5 cannot be adjusted; the wiring component 5 can also be indirectly installed on the mounting frame 11 of the slide seat 3 through the adjustment frame 4. In this structure, the height of the wiring component 5 can be adjusted through the adjustment frame 4.

[0026] The wiring member 5 and the mounting frame 11 or the adjusting frame 4 can be detachably connected by means of snap connection, thread connection or magnetic attraction.

[0027] When the wiring component 5 is indirectly installed on the mounting frame 11 of the slide seat 3 through the adjusting frame 4, a vertical slide groove 11-2 is provided on the front side of the mounting frame 11, and the adjusting frame 4 is installed in the slide groove 11-2. The adjusting frame 4 can move up and down along the slide groove 11-2, so that the wiring component 5 installed on the adjusting frame 4 can move up and down to adjust the height.

[0028] A top plate 11-1 is provided on the top of the mounting frame 11, and a horizontal plate 4-1 is provided on the top of the adjusting frame 4. A vertical screw rod 13 passes through the top plate 4-1 and the horizontal plate 4-1 at the same time, and an adjusting nut 14 is threadedly connected to both ends of the screw rod 13. A spring 12 is sleeved on the screw rod 13, and the upper end of the spring 12 contacts the top plate 4-1 and the lower end contacts the horizontal plate. By rotating the adjusting nut 14, the adjusting frame 4 can be driven to move up and down along the slide groove 11-2, thereby adjusting the height of the wiring member 5 to control the depth of the lower end of the wiring member 5 extending into the gap between the two pressing rollers 10.

[0029] Two arc-shaped receiving plates 4-2 are provided at the lower end of the adjustment frame 4. When in use, the lower end of the wiring member 5 is passed downward through the space surrounded by the two arc-shaped receiving plates 4-2, and the wiring member 5 is supported by the two arc-shaped receiving plates 4-2. At the same time, the middle or upper part of the wiring member 5 is fixed to the adjustment frame 4 by means of clamping, bolt connection or magnetic attraction.

[0030] The thread end fixing mechanism 7 and the wire pressing mechanism 6 are located near the end of the wiring guide rail 2 and are respectively connected to the frame 1. The thread end fixing mechanism 7 is specifically located in front of the upper part of the gap between the two pressing rollers 10, and the wire pressing mechanism 6 is located directly above the gap between the two pressing rollers 10.

[0031] The thread end fixing mechanism 7 includes a fixing frame 7-1 arranged on the frame 1, at least one group of rollers 7-2 is arranged on the fixing frame 7-1, and an anti-slip baffle 7-3 is arranged above the rollers 7-2. One group of rollers 7-2 includes two rollers 7-2, and the rotating shafts 6-3 of the two rollers 7-2 are in a vertical state. A gap is left between the two rollers 7-2 of the group for placing the electric heating wire 9, and the anti-slip baffle 7-3 is located above the gap. The anti-slip baffle 7-3 can prevent the electric heating wire 9 from slipping upward from between the two rollers 7-2.

[0032] The wire crimping mechanism 6 includes a wire crimping frame 6-1, on which a wire crimping plate 6-2 is arranged, the middle part of the wire crimping plate 6-2 is connected to the wire crimping frame 6-1 through a rotating shaft 6-3, a wire crimping groove 6-4 is opened at the lower end of the wire crimping plate 6-2, a protrusion 6-5 is arranged at the upper end of the wire crimping plate 6-2, and a stopper 6-6 is arranged on the wire crimping frame 6-1, and the stopper 6-6 and the protrusion 6-5 limit the wire crimping plate 6-2 to only swing outward.

[0033] The wiring member 5 includes a main body plate 5-1, an arc plate 5-2 is arranged at the lower part of the main body plate 5-1, the arc plate 5-2 and the main body plate 5-1 form a wire passage, and a limit ring 5-3 is arranged at the top of the main body plate 5-1. When the electric heating wire 9 is installed, the electric heating wire 9 first passes through the limit ring 5-3 and then passes through the wire passage and passes out from the lower end of the passage.

[0034] Before wiring, a heating wire 9 is passed through the wiring component 5, and the reserved wire end of the heating wire 9 is passed through the bottom of the wire pressing groove 6-4, and then the wire end is fixed on the wire end fixing mechanism 7, and the reserved wire end part is fixed by the wire pressing mechanism 6 and the wire end fixing mechanism 7, so that when the slide 3 carries the wiring component 5 along the wiring guide rail 2 away from the wire pressing mechanism 6, the subsequent heating wire 9 is automatically output through the lower port of the wiring component 5, thereby placing an electric heating wire 9 in the gap between the two pressing rollers 10, and then the pressing roller 10 is rotated to press the placed electric heating wire 9 between the two fabrics, and then the slide 3 moves in the opposite direction with the wiring component 5 to place the second electric heating wire 9, and the pressing roller 10 rotates to press the second electric heating wire 9 between the two fabrics, and the above steps are repeated until the wiring of the entire serpentine heating wire 9 is completed. The end of the electric heating wire 9 located at the wire pressing groove 6-4 and the wire end fixing mechanism 7 is brought between the two fabrics during the rotation of the pressing roller 10, thereby forming a straight line portion next to the snake-shaped electric heating wire 9. Finally, when the wiring member 5 returns to its original position, the wiring member 5 continues to move outward along the wiring guide rail 2, and the remaining electric heating wire 9 is placed on the outside of the fabric through the wiring member 5. At the same time, the wiring member 5 drives the wire pressing plate 6-2 to swing outward, and the end of the wire is separated from the control of the wire pressing groove 6-4 and pushed to the outside of the fabric by the wiring member 5. In this way, both end portions of the electric heating wire 9 are arranged on the outside of the surface layer of the electric blanket, which is convenient for the subsequent cutting of the electric blanket and the installation of the controller.

[0035] The wiring drive mechanism 8 includes a driving wheel 8-1, a driven wheel 8-2 and a chain 8-3 installed on the driving wheel 8-1 and the driven wheel 8-2. The chain 8-3 is parallel to the wiring guide rail 2. The driving wheel 8-1 is driven by the wiring drive motor. The slide 3 is connected to the chain 8-3 on one side.

[0036] The driving wheel 8 - 1 is driven by a motor, and the slide 3 is driven to move back and forth by the forward and reverse rotation of the motor.

[0037] At the same time, the present application can also be used for the wiring of double-wire dual-control electric blankets. Two slides 3 are installed on the wiring guide rail 2, one slide 3 is driven by the chain 8-3 on the lower side, and the other slide 3 is driven by the chain 8-3 on the upper side. A wire pressing mechanism 6 and a wire end fixing mechanism 7 are respectively arranged at both ends of the wiring guide rail 2.

[0038] The utility model is used to arrange the heating wire 9 between two pressing rollers 10 arranged front and back and in a horizontal state. When working, the heating wire 9 is first passed through the wiring member 5 and then the reserved wire end portion of the heating wire 9 is fixed in the gap between the two pressing rollers 10 by the wire pressing mechanism 6, and then the wire end portion is fixed on the wire end fixing mechanism 7. When the slide 3 moves along the wiring guide rail 2, the remaining heating wire 9 is gradually arranged in the gap between the pressing rollers 10 by the wiring member 5.

[0039] The heating wire 9 is laid out by the reciprocating movement of the slide 3 and the rotation of the pressing roller 10. After one heating wire 9 is laid out, the slide 3 returns to the initial position and continues to move outward, and the remaining heating wires 9 and the heating wires 9 reserved at the wire end fixing mechanism 7 are simultaneously laid outward to obtain the wire end portion for subsequent installation of the controller.

[0040] The utility model is applicable to a new process for wiring between two pressing rollers 10, and can improve the wiring efficiency of the electric heating wire 9 of the electric blanket.
