[0020] Compared with the prior art, the beneficial technical effects of the present invention are:

[0021] The electric blanket processing equipment of the present invention can automatically complete the laying, wiring, compounding and slitting of the cloth, greatly improving the production efficiency and ensuring the product quality; by adopting a brush roller as a compound pressing roller, even if the thickness of the cloth deviates, the surface cloth can be elastically pressed to the bottom cloth so that the bonding surface roasted by the flame is effectively compounded together. At the same time, compared with a rigid roller, there is no need to set an annular needle clearance groove, and there is no need to consider whether the arrangement position of the needle matches the compound roller, so the arrangement of the heating pipeline can be set more flexibly. The electric blanket processing equipment of the present invention ensures uniform downward pressure and improves the composite bonding effect by adopting a brush roller as a compound roller for hot pressing compounding.

[0022] In addition, by arranging the acupuncture unit below the acupuncture holes arranged in rows, the acupuncture unit has its own lifting acupuncture cylinder, and the acupuncture needles are lifted and lowered in rows, avoiding the lifting of each acupuncture needle individually, and the structure and lifting action are simpler, easy to implement, and the failure rate is also low. By arranging the acupuncture holes in the front and rear areas, the hanging wires are turned corresponding to the head and foot of the electric blanket, and the processing of electric blankets of most specifications can be completed, without the need to open acupuncture holes in a large area of ​​the entire support plate. By arranging the acupuncture needles in the rear end area in an inclined manner, the needle body of the acupuncture needle almost coincides with the diameter of the brush roller that rolls over, which can ensure that the face cloth will not be torn by the acupuncture needles during the falling process, so that the face cloth is not damaged. By setting multiple igniter heads on the gas pipe, the gas can be ignited at the same time, and the gas can be ignited instantly and synchronously without waiting for the flame to be transferred and ignited; by the coordinated setting of the gas outlet and the long slot, the high-speed flowing gas ejected from the gas outlet triggers the Bernoulli effect in the long slot, and the surrounding air enters the long slot and is driven by the high-speed flowing gas to eject downward, fully mixing the air and gas, and improving the combustion efficiency when ignited. At the same time, the long slot serves as a combustion chamber with an opening facing downward, forming a flame ejected downward, which can fully heat the velvet surface of the base fabric and the surface fabric. By setting the small transverse guide rail and the compression spring, it can ensure that the working gear is always pressed against the longitudinal rack on the outside, avoiding the problem of jamming and position accuracy drift caused by assembly errors of the two longitudinal racks during walking. By ensuring the processing accuracy of the top surface of the main frame installation, the overall operation stability of the equipment is improved. By adding a hot hole assembly, the lead hole can be hot-punched on the base fabric at the lead position before the wiring of the heating pipeline, avoiding manual hole opening during later assembly and improving the operation efficiency. By setting up multiple pairs of thread end clamps and wire cutters, different wiring patterns can be matched to meet the production needs of electric blankets of various specifications. By setting up an internal floating frame in the unwinding chassis, the support roller can be adjusted left and right, and the unwinding position of the surface fabric roll can also be adjusted left and right. In conjunction with the cloth edge detection sensor, the surface fabric can be output stably to avoid left and right deviation. By setting up the gantry cutting frame that can adjust the position longitudinally on the cutting table chassis, the distance between the incision of the cross-cutting component and the main frame can be adjusted to ensure that it is an integer multiple of the length of the finished electric blanket. This facilitates the intermittent traction of the electric blanket and ensures that the base fabric is exactly in the wiring position on the pallet while the transverse cutting is completed. By setting up a longitudinal cutting component including three groups of longitudinal cutting units, it is possible to complete the trimming of both sides and perform the middle slitting as needed.

[0023] The electric blanket processing technology of the present invention can avoid bulging at the needle position by reasonably arranging the brush roller to elastically compress the surface cloth and laminate it to the base cloth; the needles are tilted in the rear end area to be brought into a nearly flat position to avoid tearing the surface cloth; in the front end area, most of the electric heating pipelines have been composited and fixed in the middle without affecting the wiring, and the needles are withdrawn just before rolling to avoid tearing the surface cloth by the needles.

[0039] In a specific embodiment, Figures 1 to 9 As shown, the electric blanket processing equipment of the present invention comprises:

[0040] The main frame 1 is a profile welded structure frame. A support plate 101 is horizontally arranged on the top of the main frame 1. A plurality of needle holes 1011 are opened on the support plate 101. A needle mechanism 3 that can be raised and lowered is arranged below the support plate 101. The top of the main frame 1 is guided and driven by a horizontally arranged longitudinal guide rail 102 and a longitudinal rack 103 to connect a wiring mechanism 2 and a composite mechanism 4, that is, the wiring mechanism 2 and the composite mechanism 4 reciprocate linearly on the same set of longitudinal guide rails 102 and longitudinal racks 103. The wiring mechanism 2 cooperates with the needle mechanism 3 to wire the heating pipeline on the base fabric 12. The heating pipeline is a resistance line or a water pipeline. A brush roller 401 for pressing the surface fabric 13 is horizontally arranged at the bottom of the composite mechanism 4. The two ends of the brush roller 401 are supported by a sliding bearing seat, the bearing seat slides in the vertical direction, and the top of the bearing seat is pressurized by an action cylinder. The diameter of a single bristle of the brush roller 401 is not less than 1 mm.

[0041] The front end of the main frame 1 is provided with a surface cloth unwinding device 9 and a bottom cloth unwinding device 10. The surface cloth unwinding device 9 sets up a surface cloth roll, and the surface cloth 13 is output upward through the top guide roller group to the brush roller 401 after being led out. The bottom cloth unwinding device 10 sets up a bottom cloth roll, and the bottom cloth 12 is flattened backward on the support plate 101 after being led out and continues to be transported backward. Both the surface cloth unwinding device 9 and the bottom cloth unwinding device 10 adopt double rollers to support unwinding, and the double rollers set up the surface cloth roll or the bottom cloth roll.

[0042] The cutting device 7 is arranged at the rear end of the main frame 1 to receive the composite base fabric 12 and the surface fabric 13. The composite electric blanket can be pulled and cut.

[0043] By using the brush roller 401 as a composite pressing roller, even if the thickness of the fabric is different, the surface fabric 13 can be elastically pressed against the bottom fabric 12 so that the bonding surface baked by the flame is effectively compounded together. At the same time, compared with a rigid roller, there is no need to set an annular needle clearance groove, and there is no need to consider whether the arrangement position of the needle matches the composite roller, so the arrangement of the heating pipeline can be set more flexibly. The electric blanket processing equipment of the present invention uses a brush roller as a composite roller for hot pressing and compounding, which ensures uniform downward pressure and improves the composite bonding effect.

[0044] In a specific embodiment of the present invention, Figures 2 to 4 As shown, the area where the needling holes 1011 are provided on the support plate 101 is divided into two and is located at the front and rear ends of the support plate 101. Multiple needling holes 1011 are arranged in a row with equal spacing in the horizontal direction, and both areas include multiple rows of needling holes 1011. Correspondingly, the needling mechanism 3 includes multiple needling units, the number of which is equal to the number of rows of needling holes 1011 and is arranged one-to-one, and the needling units are arranged below the entire row of needling holes 1011.

[0045] Specifically, if Figure 4 and Figure 7 As shown, the acupuncture unit includes a needle 301, a square tube 302 and a needle cylinder 303. A plurality of needles 301 are installed on the top surface of the square tube 302 at equal intervals, and the number of needles 301 is consistent with the number of holes in the whole row of acupuncture holes 1011 and is arranged one by one. The square tube 302 is arranged horizontally below the whole row of acupuncture holes 1011, and two acupuncture cylinders 303 are arranged at both ends of the square tube 302. The acupuncture cylinders 303 are fixedly installed on the main frame 1, and the downward piston rod of the acupuncture cylinder 303 is connected to the end of the square tube 302 through a connecting plate.

[0046] Specifically, if Figure 7 As shown, the acupuncture units in the rear end area are all arranged obliquely, and the top ends of the acupuncture needles 301 are tilted backward to protrude from the corresponding acupuncture holes 1011.

[0047] By arranging the acupuncture unit below the acupuncture holes 1011 arranged in rows, the acupuncture unit has its own lifting acupuncture cylinder 303, and the acupuncture needles 301 are lifted and lowered in rows, avoiding the lifting and lowering of each acupuncture needle 301 individually, and the structure and lifting action are simpler, easy to implement, and the failure rate is also low. By arranging the acupuncture holes 1011 in the front and rear areas, the wire hanging turns are made corresponding to the head and foot of the electric blanket, and the processing of electric blankets of most specifications can be completed, without the need to open acupuncture holes 1011 in a large area of ​​the entire support plate 101. By arranging the acupuncture needles 301 in the rear area at an angle, the needle body of the acupuncture needle 301 almost coincides with the diameter of the brush roller 401 that rolls over, which can ensure that the face cloth 13 will not be torn by the acupuncture needles 301 during the falling process, so that the face cloth 13 is not damaged.

[0048] In a specific embodiment of the present invention, Figure 4 and Figure 8 As shown, the flame assembly 402 of the composite mechanism 4 includes a gas distribution pipe 4021 and an igniter head 4025. The gas distribution pipe 4021 for introducing gas is arranged horizontally and its two ends are fixedly connected to the inner walls of the vertical plates on both sides of the composite mechanism 4. The gas distribution pipe 4021 is made of thick-walled pipe. The igniter head 4025 is installed on the outer wall of the gas distribution pipe 4021 through a pipe clamp 4024. A plurality of igniter heads 4025 are arranged at equal intervals along the length direction of the gas distribution pipe 4021. The igniter head 4025 introduces low-energy high-voltage electricity for ignition. In a specific embodiment, the number of igniter heads 4025 is four, and the four igniter heads 4025 use the same high-voltage power supply.

[0049] Specifically, if Figure 8 As shown, a gas outlet hole 4022 connected to the middle hole is vertically opened at the bottom of the gas distribution pipe 4021, and multiple gas outlet holes 4022 are arranged at equal intervals along the length direction of the gas distribution pipe 4021, and the diameter of the gas outlet holes 4022 is 1 to 2.5 mm. A long slot 4023 is also opened on the outer wall of the bottom of the gas distribution pipe 4021, and the long slot 4023 is arranged along the length direction of the gas distribution pipe 4021, and the width of the long slot 4023 is 5 to 8 mm and the depth is not less than 4 mm. The gas outlet hole 4022 is opened on the bottom wall of the long slot 4023, and the lead end of the igniter head 4025 is led out into the long slot 4023 and can generate electric sparks with the side wall of the long slot 4023.

[0050] By arranging a plurality of igniter heads 4025 on the gas pipe 4021, the ejected gas can be ignited at the same time, and the ignition can be achieved instantly and synchronously, without waiting for the flame to be transferred and ignited; by the coordinated arrangement of the gas outlet 4022 and the long slot 4023, the high-speed flowing gas ejected from the gas outlet 4022 triggers the Bernoulli effect in the long slot 4023, and the surrounding air enters the long slot 4023 and is driven by the high-speed flowing gas to eject downward, fully mixing the air and gas, and improving the combustion efficiency when ignited. At the same time, the long slot 4023 serves as a combustion chamber with an opening facing downward, forming a flame ejected downward, which can fully heat the velvet surface relative to the base fabric 12 and the surface fabric 13.

[0051] In a specific embodiment of the present invention, Figure 1 , Figure 4 and Figure 5As shown, the wiring mechanism 2 includes a gantry and a wiring head 201, a Y-axis drive assembly 202 and an X-axis drive assembly 203 arranged on the gantry. The wiring head 201 for guiding the heating pipeline is slidably arranged on the crossbeam of the gantry through a transverse guide rail, and the Y-axis drive assembly 202 drives the wiring head 201 to reciprocate horizontally. The Y-axis drive assembly includes a Y-axis motor and a synchronous belt. The Y-axis motor drives the synchronous belt to rotate horizontally to drive the sliding plate frame of the wiring head 201 to move. The wiring head 201 is provided with a guide sleeve for guiding the heating pipeline, and the vertical guide sleeve at the bottom can also realize vertical movement through a cylinder, that is, movement in the Z-axis direction. The X-axis drive assembly 203 is arranged at the bottom of the vertical plates at both ends of the gantry, and the X-axis drive assembly 203 cooperates with the longitudinal rack 103 to drive the wiring mechanism 2 to reciprocate longitudinally.

[0052] Specifically, if Figure 5 As shown, the X-axis drive assembly 203 includes an X-axis motor, a slide plate, a small transverse guide rail 2031 and a compression spring 2033. The X-axis motor is mounted on the slide plate with its head facing downward, and a working gear 2032 is mounted on the output shaft of the X-axis motor facing downward, and the working gear 2032 is meshed with the longitudinal rack 103. The slide plate is guided and slid on the two small transverse guide rails 2031, and the two ends of the small transverse guide rails 2031 are mounted on the bottom wall of the drive box at the bottom of the gantry, and an opening is provided on the bottom wall of the drive box. The compression spring 2033 is sleeved on the outer end of the small transverse guide rail 2031, and the compression spring 2033 pushes the slide plate inward.

[0053] Specifically, the top surface of the main frame 1 on which the longitudinal guide rail 102 and the longitudinal rack 103 are mounted is formed by one-time clamping and processing by a large-scale machining center, thereby ensuring the flatness and height consistency of the mounting surfaces on both sides.

[0054] By setting the small transverse guide rail 2031 and the compression spring 2033, it is possible to ensure that the working gear 2032 is always pressed against the longitudinal rack 103 on the outside, thereby avoiding the problems of jamming and positional accuracy drift caused by assembly errors of the two longitudinal racks 103. By ensuring the machining accuracy of the top surface of the main frame 1, the overall operation stability of the equipment is improved.

[0055] In a specific embodiment of the present invention, Figure 1 , Figure 5 and Figure 6As shown, the electric blanket processing equipment of the present invention also includes a hole-ironing component 8, which includes a hole-ironing cylinder, a clamping arm and a hot pen 801. The hole-ironing cylinder is vertically arranged beside the bottom of the wiring head 201, and the downward piston rod end of the hole-ironing cylinder is connected to the clamping arm. The cantilever end of the clamping arm clamps the hot pen 801, and the hot pen 801 is vertically arranged and can iron out a lead hole on the base fabric 12. A heating sleeve and a temperature sensor are sleeved on the top of the hot pen 801 to control its working temperature. The support plate 101 is provided with a hot pen through hole 1012 at the position of the lead hole.

[0056] As we all know, electric blankets are connected to external power sources at the junction box, which often includes two plastic covers that buckle together. In the past, during the production process, workers were required to use scissors to cut out lead holes at the raised part of the lead head of the electric heating pipe at the junction box during assembly. This was not only time-consuming and laborious, but also the sizes of the processed lead holes were inconsistent and sometimes leaked out of the junction box, affecting the quality of the product.

[0057] By adding the punch hole assembly 8, before the heating pipeline is laid, a lead hole can be punched out on the base fabric 12 at the lead position by punching holes, thereby avoiding manual drilling during later assembly and improving work efficiency.

[0058] In a specific embodiment of the present invention, Figure 1 , Figure 3 and Figure 6 As shown, a wire end clamp 5 and a wire cutter 6 are also provided on both sides of the front end of the support plate 101. The wire end clamp 5 and the wire cutter 6 are provided in pairs, and multiple pairs of wire end clamps 5 and wire cutters 6 are provided on both sides of the front end area. The wire end clamp 5 can clamp the wire ends of the heating pipelines derived from the wiring head 201, so as to facilitate the wiring. After the wiring is completed, the wiring head 201 guides the heating pipelines to the wire cutters 6, and the wire cutters 6 cut them, so as to facilitate the next wiring.

[0059] By arranging a plurality of pairs of wire end clips 5 and wire cutters 6, different wiring patterns can be matched to meet the production requirements of electric blankets of various specifications.

[0060] In a specific embodiment of the present invention, Figure 1 and Fig. 9 As shown, the surface cloth unwinding device 9 includes an unwinding chassis 901, an inner floating frame 902, an adjustment cylinder 903, a support roller 904 and a high-position guide roller 905. The inner floating frame 902 is slidably connected in a transverse direction in the unwinding chassis 901. The adjustment cylinder 903 is transversely installed inside the unwinding chassis 901 and can drive the inner floating frame 902 to move transversely. Two support rollers 904 for supporting the surface cloth roll are arranged on the top of the inner floating frame 902. The support rollers 904 are equipped with a reduction motor for rotational drive. The high-position guide roller 905 is installed above the unwinding chassis 901 through a column.

[0061] Specifically, if Fig. 9 As shown, a transverse bottom guide rail 9021 is disposed at the bottom of the inner floating frame 902 , and a plurality of guide wheels 9011 for supporting the bottom guide rail 9021 are disposed on the inner side of the unwinding bottom frame 901 .

[0062] Obviously, the main structure of the bottom fabric unwinding device 10 is consistent with that of the surface fabric unwinding device 9, except that the high-position guide roller 905 is not provided, and an internal floating adjustable structure is also adopted.

[0063] By setting an inner floating frame 902 in the unwinding chassis 901, the support roller 904 can be adjusted left and right, and the unwinding position of the surface fabric roll can also be adjusted left and right. In conjunction with the cloth edge detection sensor, the surface fabric 13 can be stably output to avoid left and right deviation.

[0064] In a specific embodiment of the present invention, Figures 1 to 4 As shown, the cutting device 7 includes a cutting table frame 701, a traction roller 702, a longitudinal cutting assembly 703 and a transverse cutting assembly 704. A longitudinal track is arranged on the top of the cutting table frame 701 and a gantry cutting frame is slidably connected thereto. A reduction motor and a longitudinal transmission synchronous belt are also arranged on the cutting table frame 701. The synchronous belt is connected to the gantry cutting frame through a clamping block and drives it to move horizontally forward and backward. The traction roller 702 is horizontally arranged on the gantry cutting frame and can pull the composite electric blanket backward. The longitudinal cutting assembly 703 is arranged on the gantry cutting frame and is located in front of the traction roller 702, and can complete trimming and longitudinal segmentation. The transverse cutting assembly 704 is arranged on the gantry cutting frame and is located behind the traction roller 702, and can complete transverse segmentation.

[0065] Specifically, the longitudinal cutting assembly 703 includes three groups of longitudinal cutting units, and the three groups of longitudinal cutting units are respectively located at the left, middle and right positions of the crossbeam. The longitudinal cutting unit includes a vertical driving cylinder, a motor and a disc knife. The transverse cutting assembly 704 includes a clamping plate, a transverse driving member and a transverse cutting unit. The clamping plate is arranged in parallel behind the traction roller 702 and can press the electric blanket on the table panel below. The transverse driving member drives the transverse cutting unit to complete transverse reciprocating linear motion along the cutting seam between the clamping plate and the traction roller 702. The transverse cutting unit includes a slide plate, a motor and a disc knife; the transverse driving member includes a transverse guide rail and a transverse rack driving structure, which can drive the transverse cutting unit to move transversely linearly.

[0066] By arranging the gantry cutting frame capable of longitudinally adjusting the position on the cutting table bottom frame 701, the distance between the cut of the cross-cutting assembly 704 and the main frame 1 can be adjusted to ensure that it is an integral multiple of the length of the finished electric blanket, so that the electric blanket can be pulled at intervals to ensure that the base fabric 12 is exactly at the wiring position on the pallet 101 while the cross-cutting is completed. By arranging the longitudinal cutting assembly 703 including three groups of longitudinal cutting units, it is possible to complete the trimming of both sides and perform the middle slitting as needed.

[0067] The working process of the electric blanket processing equipment of the present invention is as follows: when working, the bottom fabric roll is led out from the bottom fabric unwinding device 10 and laid on the support plate 101 of the main frame 1, and transported backward; similarly, the surface fabric roll is led out from the surface fabric unwinding device 9, and after being transported by the high-position guide roller 905 and multiple top guide rollers, it is overlapped with the bottom fabric 12 at the brush roller 401, and the composite electric blanket semi-finished product is pulled and transported to the unloading platform at the rear by the traction roller 702 of the cutting device 7. The operator selects the corresponding setting program on the touch screen of the control console according to the specifications of the electric blanket to be processed, and starts the work. The first pressing plate 204 of the wiring mechanism 2 and the perforated pressing plate of the composite mechanism 4 are pressed down on the bottom fabric 12, the needling mechanism 3 is started, the needling unit selected by the program moves, and the corresponding needling cylinder 303 pulls the square tube 302 upward, and the corresponding row of needles 301 pass through the needling holes 1011 upward. The perforating assembly 8 of the wiring mechanism 2 is in motion. First, at the selected position, a lead hole is processed on the base fabric 12 by the perforating pen 801. The routing head 201 is in motion to clamp the heating pipeline thread end at the thread end clamp 5, and the heating pipeline is output through the X and Y axis movements to be routed between the protruding needles 301 according to the pattern selected by the program. After the routing is completed, the online shear 6 cuts the heating pipeline, and the wiring mechanism 2 returns to its position. The composite mechanism 4 starts to move, moving longitudinally from back to front, and the brush roller 401 guides the surface fabric 13 and presses it onto the base fabric 12. At the same time, the flame assembly 402 starts to supply gas, and the four igniter heads 4025 ignite at the same time. The downward burning port of the gas pipe 4021 is instantly and synchronously ignited, and the flame melts the chemical fiber on the inner velvet surface of the base fabric 12 and the surface fabric 13, so that the base fabric 12 and the surface fabric 13 that are squeezed together are bonded together. After a length of electric blanket is composited, the flame is turned off, and the composite mechanism 4 returns to its position. The composite electric blanket semi-finished product is pulled backward by the traction roller 702, and the longitudinal cutting assembly 703 completes the edge cutting during the conveying process. After conveying a length of electric blanket to the unloading table, the cross-cutting assembly 704 completes the cross-cutting, and the four sides of the electric blanket are cut, stacked together and transferred to the next process.

[0068] In summary, the electric blanket processing equipment of the present invention adopts a brush roller 401 as a composite pressure roller, which can elastically press the surface cloth 13 to the bottom cloth 12 even if the thickness of the cloth deviates, so that the bonding surface roasted by the flame is effectively compounded together. At the same time, compared with rigid rollers, there is no need to set an annular needle clearance groove, and there is no need to consider whether the arrangement position of the needles matches the composite roller, so the arrangement of the heating pipeline can be set more flexibly. The electric blanket processing equipment of the present invention adopts a brush roller as a composite roller for hot pressing and compounding to ensure uniform downward pressure and improve the composite bonding effect. In addition, by arranging the acupuncture unit below the acupuncture holes 1011 arranged in rows, the acupuncture unit has its own lifting acupuncture cylinder 303, and the needles 301 are lifted and lowered in rows, avoiding the lifting of each needle 301 individually, and the structure and lifting action are simpler, easy to implement, and the failure rate is also low. By setting the needle holes 1011 in the front and rear areas, the wires are turned corresponding to the head and foot of the electric blanket, and most specifications of electric blankets can be processed without the need to open the needle holes 1011 in a large area of ​​the entire support plate 101. The needles 301 in the rear area are tilted, and the needles 301 are almost the same as the diameter of the brush roller 401, which can ensure that the surface cloth 13 will not be torn by the needles 301 during the falling process, so that the surface cloth 13 is not damaged. By arranging a plurality of igniter heads 4025 on the gas pipe 4021, the gas ejected can be ignited at the same time, and the gas can be ignited synchronously instantly without waiting for the flame to be transmitted and ignited; by the coordinated arrangement of the gas outlet 4022 and the long slot 4023, the high-speed flowing gas ejected from the gas outlet 4022 triggers the Bernoulli effect in the long slot 4023, and the surrounding air enters the long slot 4023 and is driven by the high-speed flowing gas to eject downward, fully mixing the air and gas, and improving the combustion efficiency when ignited. At the same time, the long slot 4023 serves as a combustion chamber with an opening facing downward, forming a flame ejected downward, which can fully heat the velvet surface of the base fabric 12 and the face fabric 13. By arranging the small transverse guide rail 2031 and the compression spring 2033, it can be ensured that the working gear 2032 is always pressed against the longitudinal rack 103 on the outside, avoiding the problems of jamming and position accuracy drift caused by the assembly error of the two longitudinal racks 103 during walking. By ensuring the processing accuracy of the top surface of the main frame 1, the overall operation stability of the equipment is improved. By adding the hole-burning component 8, before wiring the heating pipeline, the lead hole can be burned on the base fabric 12 at the lead position by the hole-burning method, avoiding manual hole drilling during later assembly and improving the work efficiency. By setting multiple pairs of thread end clamps 5 and wire cutters 6, different wiring patterns can be matched to meet the production needs of electric blankets of various specifications. By setting the inner floating frame 902 in the unwinding chassis 901, the support roller 904 can be adjusted left and right, and the unwinding position of the surface fabric roll can also be adjusted left and right. In conjunction with the cloth edge detection sensor, the surface fabric 13 can be output stably to avoid left and right deviation.By arranging the gantry cutting frame capable of longitudinally adjusting the position on the cutting table bottom frame 701, the distance between the cut of the cross-cutting assembly 704 and the main frame 1 can be adjusted to ensure that it is an integral multiple of the length of the finished electric blanket, so that the electric blanket can be pulled at intervals to ensure that the base fabric 12 is exactly at the wiring position on the pallet 101 while the cross-cutting is completed. By arranging the longitudinal cutting assembly 703 including three groups of longitudinal cutting units, it is possible to complete the trimming of both sides and perform the middle slitting as needed.

[0069] A process for processing an electric blanket, using the electric blanket processing equipment in any of the above embodiments to process the electric blanket, using a brush roller 401 to elastically compress the facing fabric 13 and laminate it onto the bottom fabric 12.

[0070] Furthermore, in the electric blanket processing technology of the present invention, the needles 301 that are inclined and extended are used for hanging wires in the rear end area of ​​the support plate 101, which can avoid tearing and damaging the surface cloth 13 during the rolling process of the brush roller 401. At the same time, the needles 301 in the front end area of ​​the support plate 101 extend vertically through the needle holes 1011. When the brush roller 401 moves to a position close to the needles 301 in the front end area during the compounding process, the program controls the needle cylinder 303 to descend and return with the needles 301, which can also avoid tearing and damaging the surface cloth 13 that is laid over.

[0071] By properly arranging the brush roller 401 to elastically press and laminate the facing cloth 13 onto the base cloth 12, bulging at the position of the needles 301 can be avoided. By tilting the needles 301 in the rear end area to bring them into a nearly flat position, tearing of the facing cloth 13 can be avoided. In the front end area, most of the electric heating pipelines have been laminated and fixed in the middle without affecting the wiring. The needles are withdrawn just before rolling, which also avoids tearing of the facing cloth 13 by the needles 301.
