Description

TECHNICAL FIELD

[0001] The present application relates to an electric blanket production equipment, in particular to an electric blanket production equipment and production method. BACKGROUND

[0002] The electric blanket includes two layers of fabric, and a serpentine electric heating wire is arranged between the two layers of fabric. In the processing of the electric blanket, manual work is still largely used. Generally, the two layers of fabric are first glued and bonded, and then the electric heating wire is manually threaded and arranged. This method is very low in efficiency. There are also some automatic electric blanket production equipment. Generally, the electric heating wire is arranged on the lower layer of fabric, and then the upper layer of fabric is covered and bonded. In order to ensure that the arranged electric heating wire will not move during the processing, a hanging needle is arranged before the electric heating wire is arranged. When the electric heating wire is arranged, the electric heating wire is hung on the hanging needle for positioning, and then the upper layer of fabric is covered and bonded. On the one hand, the hanging needle needs to be realized by a complex hanging mechanism, and the position of the hanging needle needs to be adjusted for different specifications of the electric blanket. The adjustment process is relatively complex, and when the production type of the electric blanket needs to be frequently changed, the processing efficiency will be seriously affected. On the other hand, when the electric heating wire passes through the hanging needle, the bending radius is small, forming a structure similar to a right angle. In addition to affecting the appearance, the small bending radius may also affect the normal use of the electric heating wire. At the same time, in the processing of the electric blanket, the two layers of fabric are generally bonded by spraying glue. During the spraying process, a large amount of pollutants will be released into the air, resulting in an unenvironmentally friendly production method. SUMMARY

[0040] This invention discloses an electric blanket production equipment and production method, which will be further described below with reference to the accompanying drawings.

[0041] like Figure 1 As shown, the electric blanket production equipment of the present invention includes a frame 1, a first feeding mechanism 2, a second feeding mechanism 3, an adhesive feeding mechanism, a heating device 5, a wiring device 6, and a pressing mechanism 7, etc.

[0042] The frame 1 is used to support and install various mechanisms. The frame 1 is generally a frame structure, and all parts are installed on the frame 1.

[0043] The two layers of fabric required for the production of electric blankets are provided by the first feeding mechanism 2 and the second feeding mechanism 3, respectively. Both the first feeding mechanism 2 and the second feeding mechanism 3 are installed on the frame 1. In this specific embodiment, in order to facilitate operation and insertion of the heating wire 12, the pressing mechanism 7 is located at the front end of the frame 1. The first fabric 10 and the second fabric 11 need to enter from the front and rear ends of the pressing mechanism 7, respectively. Therefore, the first feeding mechanism 2 is set in the middle and above the frame 1, and the second feeding mechanism 3 is set in the lower part of the front end of the frame 1. The first fabric 10 of the first feeding mechanism 2 enters the pressing mechanism 7 from the rear to the front, while the second fabric 11 of the second feeding mechanism 3 enters the pressing mechanism 7 from the front under the guidance of the roller.

[0044] The adhesive supply mechanism is arranged on the frame 1 to arrange solid adhesive on the surface of the first fabric 10 or the second fabric 11. In the embodiment, since the first fabric 10 is supplied from the back to the front, there is space to arrange the adhesive supply mechanism, so the solid adhesive is arranged on the surface of the first fabric 10 by the adhesive supply mechanism.

[0045] The present application uses solid adhesive to replace the original glue spraying process. The solid adhesive forms liquid glue droplets adhered to the surface of the fabric after being heated, which can prevent pollutants from spreading into the air, thereby reducing pollution to the environment.

[0046] The solid adhesive includes hot melt adhesive roll 13 and solid adhesive particles 14, and the adhesive supply mechanism has different structures according to different solid adhesives.

[0047] The first structure is shown in Figure 1 When the solid adhesive is the hot melt adhesive roll 13, the hot melt adhesive roll 13 needs to be applied to the surface of the first fabric 10. At this time, the adhesive supply mechanism is specifically the hot melt adhesive roll supply mechanism 4, which includes a roll material roller 4-1 arranged on the frame 1, the roll material roller 4-1 is located in front of the first supply mechanism 2, the hot melt adhesive roll 13 is installed on the roll material roller 4-1, a pressure roller 4-2 is arranged on the frame 1, the hot melt adhesive roll 13 contacts the first fabric 10 after passing through the pressure roller 4-2, and the hot melt adhesive roll 13 is applied to the surface of the first fabric 10 under the action of the pressure roller 4-2 and moves forward with the first fabric 10.

[0048] The second structure is shown in Figure 5 、 Figure 6 When the solid adhesive is the adhesive particles 14, the adhesive particles 14 need to be evenly scattered on the surface of the first fabric 10. At this time, the adhesive supply mechanism is specifically the adhesive particle supply mechanism 9, which includes a material cylinder 9-1 for containing the adhesive particles 14, the material cylinder 9-1 is fixed on the frame 1, a material taking bin 9-2 is arranged at the bottom of the material cylinder 9-1, the material taking bin 9-2 is in communication with the inner cavity of the material cylinder 9-1, and a material adding opening 9-7 is opened at the top of the material cylinder 9-1. The adhesive particles 14 added to the material cylinder 9-1 are accumulated in the material taking bin 9-2, in order to prevent the adhesive particles 14 from falling off, the front end of the material taking bin 9-2 is inclined upward. A material taking frame 9-3 is arranged on the front side of the material cylinder 9-1, the material taking frame 9-3 is installed on the frame 1 through a material taking slide rail 9-5, a material pushing frame 9-4 is arranged on the front side of the material taking frame 9-3, an elastic element 9-10 is arranged between the material taking frame 9-3 and the material pushing frame 9-4, a row of material taking pipes 9-8 is arranged on the material taking frame 9-3, a row of material pushing rods 9-9 is arranged on the material pushing frame 9-4, the material pushing rods 9-9 are inserted into the front ends of the material taking pipes 9-8, a fixed top rod 9-6 is arranged on the front side of the material pushing frame 9-4, and the material taking frame 9-3 is driven by a material taking driving mechanism to move back and forth along the material taking slide rail 9-5.

[0049] The material taking pipe 9-8 is opposite the material taking bin 9-2. When the material taking frame 9-3 moves backward, the material taking pipe 9-8 enters the material taking bin 9-2 and inserts into the rubber particles 14, and the rubber particles 14 enter the material taking pipe 9-8. When the material taking frame 9-3 moves forward, the material taking pipe 9-8 carries the rubber particles 14 out of the material taking bin 9-2. Since the pushing frame 9-4 is installed on the material taking frame 9-3 through the elastic member, the pushing frame 9-4 moves forward and backward with the material taking frame 9-3. When the pushing frame 9-4 moves to the position of the jacking rod 9-6 and continues to move forward, the pushing frame 9-4 stops moving under the blocking action of the jacking rod 9-6, and the material taking frame 9-3 continues to move forward, so that the pushing rod 9-9 inserted into the material taking pipe 9-8 moves backward relative to the material taking pipe 9-8, pushes the rubber particles 14 in the material taking pipe 9-8 out, and the pushed-out rubber particles 14 fall on the horizontal first surface 10. While the first surface 10 moves forward, the rubber particle feeding mechanism 9 continuously spreads the rubber particles 14 on the first surface 10, so that the rubber particles 14 are uniformly spread on the surface of the first surface 10.

[0050] The rear end of the material taking pipe 9-8 is provided with an inclined notch at the upper part, so that the rear end of the material taking pipe 9-8 is pointed, which facilitates the rubber particles 14 to enter the material taking pipe 9-8 when the material taking pipe 9-8 is inserted into the rubber particles 14.

[0051] The heating device 5 is arranged on the frame 1 and located in front of the adhesive feeding mechanism, which is used for heating the solid adhesive on the surface of the surface material to melt the solid adhesive. The front adhesive feeding mechanism arranges the solid adhesive on the surface of the first surface 10, and the solid adhesive is used for bonding the first surface 10 and the second surface 11. Since the adhesive is solid, it needs to be heated and melted first. After being heated and melted, the adhesive is in a liquid state and is adhered to the surface of the first surface 10, and then the first surface 10 passes through the pressing mechanism 7 together with the first surface 10, so as to bond the first surface 10 and the second surface 11.

[0052] As shown in Figure 4 The heating device 5 includes a swing mechanism arranged on both sides of the frame 1, and the two ends of the heater are connected with the swing mechanisms on both sides, respectively. The swing mechanism swings the heater forward and backward, so as to heat the solid adhesive on the surface of the first surface 10. The heater keeps swinging forward and backward in order to prevent the heater from heating the same position on the first surface 10 for too long time. Since the surface material of the electric blanket is soft, it is easy to be damaged under the high-temperature baking for a long time.

[0053] The swing mechanism comprises a sliding sleeve 5-1 fixed on the frame 1, a rack 5-2 is threaded in the sliding sleeve 5-1, the rack 5-2 extends out of the sliding sleeve 5-1 at both ends and is connected with a swing frame 5-7 through connecting rods 5-6 respectively, a meshing opening 5-3 is opened on the upper part of the sliding sleeve 5-1, a swing motor 5-4 is arranged on the frame 1, a gear 5-5 on the rotating shaft 6-8 of the swing motor 5-4 is engaged with the rack 5-2 through the meshing opening 5-3. The rack 5-2 is driven to move forward and backward in the sliding sleeve 5-1 by the forward and reverse rotation of the swing motor 5-4, the swing frame 5-7 is moved forward and backward by the rack 5-2, and the heater placed or fixed on the swing frame 5-7 is moved forward and backward with the swing frame 5-7.

[0054] The heater comprises a heating cover 5-8 and an electric heating pipe 5-9 located in the heating cover 5-8, the front and rear sides of the heating cover 5-8 are in a moustache shape structure, and the heating cover 5-8 is used for reflecting the heat radiation generated by the electric heating pipe 5-9 to the surface of the first fabric 10 below.

[0055] The pressing mechanism 7 is arranged on the frame 1 and comprises two pressing rollers 7-1 arranged side by side in front and back, the first fabric 10 and the second fabric 11 are pressed together by the extrusion force of the two pressing rollers 7-1. The central axes of the two pressing rollers 7-1 are both in a horizontal state, and the two pressing rollers 7-1 are arranged side by side in front and back, the two pressing rollers 7-1 are close to each other under the action of the elastic device, so as to provide a pressing force for the fabric entering between the two pressing rollers 7-1, the first fabric 10 and the second fabric 11 are pressed together by the pressing force of the heated and melted glue, and the electric heating wire 12 placed in the gap between the two pressing rollers 7-1 is sealed between the two fabrics.

[0056] The two pressing rollers 7-1 of the pressing mechanism 7 are close to each other, and a gap is formed above the position where the two cylindrical surfaces contact each other. The electric heating wire 12 is first placed in the gap, and then the electric heating wire 12 is placed together with the first fabric 10 and the second fabric 11 through the two pressing rollers 7-1 by rotating the pressing rollers 7-1, so as to seal the electric heating wire 12 between the two fabrics. The gap between the two pressing rollers 7-1 of the pressing mechanism 7 is used as a wiring area, and the electric heating wire 12 is placed between the two pressing rollers 7-1 from above the gap. Since the two pressing rollers 7-1 are arranged side by side, the gap between the two pressing rollers 7-1 is straight. Since the cross section of the electric heating wire 12 is circular, the electric heating wire 12 is naturally in contact with the fabrics on the two pressing rollers 7-1 when the electric heating wire 12 is placed in the gap, so that the electric heating wire 12 is also in a straight state. When the electric heating wire 12 is placed between the two pressing rollers 7-1, the first fabric 10 and the second fabric 11 are moved downward by rotating the two pressing rollers 7-1, and the electric heating wire 12 is also moved downward together with the fabrics through the two pressing rollers 7-1. In the pressing process, the electric heating wire 12 can maintain a straight state. When the first fabric 10 and the second fabric 11 are adhered to each other, the electric heating wire 12 maintains a straight state in the electric heating blanket.

[0057] When the placed electric heating wire 12 passes through the pressing mechanism 7, the end of the electric heating wire 12 naturally bends under the limitation of the wiring device 6. When the wiring device 6 continues to place the remaining electric heating wire 12 in another direction, the root of the electric heating wire 12 also naturally bends, so that the electric heating wire 12 between the two straight electric heating wires 12 forms a natural circular arc, avoiding the influence of the small bending radius of the electric heating wire 12.

[0058] The present application controls the starting position and the end position of the electric heating wire 12 in the width direction by the wiring device 6, and can ensure the straightness of the electric heating wire 12 without hanging needles. The starting position and the end position can be flexibly adjusted, and the operation is simple and easy to realize.

[0059] As shown in Figure 2 , Figure 3 , the wiring device 6 comprises a wiring guide rail 6-1 fixed on the rack 1, and the wiring guide rail 6-1 is in a horizontal state. A sliding seat 6-2 is installed on the wiring guide rail 6-1, and the sliding seat 6-2 is driven by a wiring driving mechanism to move back and forth along the wiring guide rail 6-1. A wiring piece 6-3 is detachably arranged on the sliding seat 6-2, and the wiring piece 6-3 is used to place the electric heating wire 12 between the two pressing rollers 7-1.

[0060] Meanwhile, a pressing mechanism and a wire end fixing mechanism are arranged on the rack 1. The pressing mechanism is used to fix the end of the electric heating wire 12 in the gap between the two pressing rollers 7-1, and the wire end fixing mechanism is used to fix the wire end of the reserved electric heating wire 12.

[0061] The wiring member 6-3 is fixed on the slide 6-2 by plugging, clamping or magnetic attraction, the body of the wiring member 6-3 forms a downward channel, a limiting ring 6-3-1 is fixed on the top of the wiring member 6-3, in use, the electric heating wire 12 passes through the limiting ring 6-3-1 and the channel of the wiring member 6-3 in sequence, the limiting ring 6-3-1 preliminarily limits the electric heating wire 12 so that it is easier to enter the channel, the electric heating wire 12 is output from the lower end of the wiring member 6-3 after passing through the channel, and in work, the lower end of the wiring member 6-3 is located in the gap formed above the two pressing rollers 7-1, so that the electric heating wire 12 is sent to the gap between the two pressing rollers 7-1.

[0062] The thread fixing mechanism includes a fixed frame 6-15 arranged on the rack 1, at least one set of rollers 6-13 is arranged on the fixed frame 6-15, and a anti-dropping baffle 6-14 is arranged above the rollers 6-13. The set of rollers 6-13 includes two rollers 6-13 arranged horizontally, the electric heating wire 12 passes through the gap between the two rollers 6-13, and the anti-dropping baffle 6-14 can prevent the electric heating wire 12 from being dropped out of the two rollers 6-13.

[0063] The thread pressing mechanism includes a thread pressing frame 6-7, a thread pressing plate 6-9 is arranged on the thread pressing frame 6-7, the middle part of the thread pressing plate 6-9 is connected with the thread pressing frame 6-7 through a rotating shaft 6-8, the lower end of the thread pressing plate 6-9 is provided with a thread pressing groove 6-12, the upper end of the thread pressing plate 6-9 is provided with a protrusion 6-10, and a stop block 6-11 is arranged on the thread pressing frame 6-7, the thread pressing plate 6-9 can only swing outwardly by the stop block 6-11 and the protrusion 6-10.

[0064] Before wiring, a certain length of the electric heating wire 12 is reserved according to needs, the thread passes through the channel of the wiring member 6-3, the thread passes through the thread pressing groove 6-12 at the lower end of the thread pressing plate 6-9, then passes through the gap between the two rollers 6-13 of the thread fixing mechanism, and the thread pressing groove 6-12 presses the electric heating wire 12 in the gap between the two pressing rollers 7-1. The thread is temporarily fixed by the thread fixing mechanism and the thread pressing mechanism, so that when the wiring member 6-3 moves away from the thread pressing mechanism along the wiring guide rail 6-1 for the first time, the electric heating wire 12 gradually enters the wiring member 6-3 and is placed in the gap of the pressing roller 7-1 by the wiring member 6-3. When the pressing roller 7-1 rotates, the placed electric heating wire 12 and the electric heating wire 12 in the thread pressing groove 6-12 move downward together into the two fabrics under the action of external force, and the thread moves to the thread pressing groove 6-12 through the rollers 6-13 of the thread fixing mechanism.

[0065] As Figure 7As shown, as the wiring work proceeds, the wiring component 6-3 reciprocates to lay the wiring. Each heating wire 12 is inserted between two fabrics by the rotating pressing roller 7-1, thus forming a serpentine line. The reserved wire ends are inserted directly between the two fabrics through the pressing groove 6-12, ultimately forming the straight part of the side of the serpentine line.

[0066] When the wiring of an electric heating wire 12 reaches its final stage, the slide table first carries the wiring component 6-3 back to its original position, and then continues to move outward. When the wiring component 6-3 passes the wire pressing mechanism, the electric heating wire 12 moves outward, thereby causing the wire pressing plate 6-9 to swing outward, so that the wire end is separated from the wire pressing groove 6-12. The remaining part of the wire end and the remaining part of the electric heating wire 12 are carried by the wiring component 6-3 and placed outside the edge of the fabric. After the two fabrics are pressed together, both ends of the electric heating wire 12 extend outside the edge of the fabric, which facilitates the subsequent installation and wiring of the electric blanket controller.

[0067] The wiring drive mechanism can be a gear 5-5 rack 5-2 mechanism, a belt mechanism, a chain 6-5 mechanism, etc., as long as it can drive the slider along the wiring guide rail 6-1 and control the position of the slider.

[0068] In this specific embodiment, the wiring drive mechanism adopts a sprocket and chain mechanism 6-5, which includes a driving wheel 6-4, a driven wheel 6-6, and a chain 6-5 mounted on the driving wheel 6-4 and the driven wheel 6-6. The driving wheel 6-4 and the driven wheel 6-6 are mounted on the frame 1. The chain 6-5 is parallel to the wiring guide rail 6-1. The driving wheel 6-4 is driven by a wiring drive motor. The slide 6-2 is connected to the chain 6-5 on one side. When the wiring drive motor rotates forward and reverse, it drives the slide 6-2 on the chain 6-5 to reciprocate along the wiring guide rail 6-1.

[0069] like Figure 8 As shown, for a dual-wire, dual-control electric blanket, a wiring device 6 is needed to simultaneously wire the two heating wires 12.

[0077] d. The first fabric 10 and the second fabric 11 are moved by the two pressing rollers 7-1, and the electric heating wire 12 is reciprocally placed to the upper part of the gap between the two pressing rollers 7-1 by the wiring device 6.

[0078] When the electric heating wire 12 is placed in one direction, the two pressing rollers 7-1 remain stationary, and when the electric heating wire 12 is placed to the predetermined position, the two pressing rollers 7-1 are rotated to clamp the electric heating wire 12 placed in a straight line by the first fabric 10 and the second fabric 11 and adhere the first fabric 10 and the second fabric 11 by the extrusion force, and the two pressing rollers 7-1 stop rotating after rotating by a certain angle, the electric heating wire 12 is placed in the other direction by the wiring device 6, and the step is repeated until the wiring of the electric heating wire 12 is completed.

[0079] e. Repeat steps b to d to complete the continuous production of the electric blanket sheet.

[0080] In step b, the electric heating wire 12 passes through the wiring part 6-3, the length of the wire head to be reserved for the electric blanket is determined, the wiring part 6-3 is fixed on the sliding seat 6-2, and the wire head of the electric heating wire 12 is fixed on the wire head fixing mechanism after the electric heating wire 12 is pressed in the gap between the two pressing rollers 7-1 by the wire pressing mechanism.

[0081] In step d, after the wiring device 6 returns to its original position after completing the wiring of one heating wire 12, the wiring device 6 continues to move outward, placing the remaining heating wire 12 and the reserved heating wire 12 ends outward to the edge of the first fabric 10 and the second fabric 11, and finally the wiring device 6 returns to its original position.

[0082] The solid adhesive in step c can be hot melt adhesive roll 13 or solid adhesive granules 14, and different solid adhesives are fed by different feeding mechanisms.

[0083] When there is only one wiring device 6, the result is as follows: Figure 7 The continuous blank sheet of the single-wire, single-control electric blanket shown, when there are two wiring devices 6, results in the following figure. Figure 8 The continuous blank sheet of the double-line, double-control electric heating blanket shown.

[0084] The width, length, and density of the heating wires in the electric blanket can all be adjusted.

[0085] The method of this invention enables the continuous production of electric blanket sheets. After subsequent cutting, edge sealing, and installation of the control box, the finished electric blanket can be obtained. This invention can be used for the production of electric blankets of various specifications.
