The general processing method is to adopt a heat setting process, using high temperature to change the original state of the foam, and then press it through a machine, and finally cool it to become the base material of the car steering wheel heating pad. Its specific form is to convey pieces of foam material through high temperature and downward pressure, and then the thinner and denser foam material sheets are conveyed out for subsequent processing.

[0017] The beneficial effects of the present invention are as follows: 1. The foam material processing equipment described in the present invention heats the heat-conducting oil inside the oil storage tank, which can flow into the pressing surface of the pressing shaping block and the bearing surface of the shaping panel after heating, thereby increasing the temperature of the pressing surface of the pressing shaping block and the bearing surface of the shaping panel.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] Example 1: Figure 1-3 As shown, a foam material processing device according to an embodiment of the present invention includes a conveying device 1 and a pressing device 2 fixedly installed on the side of the conveying device 1. A conveying plate 4 is fixedly installed on one side of the pressing device 2. A feeding roller 1 41 and a feeding roller 2 42 are fixedly installed on both ends of the upper side of the conveying plate 4. The feeding roller 1 41 and the feeding roller 2 42 are used to convey the foam material strips into the pressing device 2. A pressing shaping block 3 is movably installed inside the pressing device 2. The pressing shaping block 3 descends to press the foam material strips inside the pressing device 2 to increase the density of the foam material strips. A multi-stage conveying roller group 5 is movably installed on the inner side of the conveying device 1 close to the pressing device 2. The multi-stage conveying roller group 5 is composed of multiple roller bodies. The long strips of foam material after being pressed are transported on the outside of the multiple roller bodies set in the multi-stage conveying roller group 5. A rewinding roller 6 is movably installed on the inner side of the conveying device 1 away from the pressing device 2. A shaping panel 22 is fixedly installed on the inner bottom of the pressing device 2. A material guide roller 21 is also movably installed on the inner side of the pressing device 2. The shaping panel 22 and the pressing shaping block 3 are on the same vertical plane. The pressing shaping block 3 presses down the long strips of foam material above the shaping panel 22. A heating oil storage tank 7 is fixedly installed above the pressing device 2. The heat-conducting oil heated in the heating oil storage tank 7 is transported to the lower pressing surface of the pressing shaping block 3 and the bearing surface of the shaping panel 22, thereby increasing the temperature of the lower pressing surface of the pressing shaping block 3 and the bearing surface of the shaping panel 22.

[0025] The heat conducting oil in the heating oil storage tank 7 in this device can quickly heat up the temperature of the downward pressing shaping block 3 required for downward pressing work, thereby reducing the standby time and improving the performance of the heat conducting oil in the heating oil storage tank 7. The spool of foam material is rolled up on the outside of the roll 6 and the roll of the multi-stage conveying roller 5 is rotated to move the spool of foam material to the outside of the roll 6.

[0026] like Figure 4As shown, the foam material strip is a strip-shaped molding material made by mixing a foam base material, a tripropyl phosphate flame retardant, a polyester silicone oil hardener, and a softener.

[0027] Multiple guide bars 23 are fixedly installed on both sides of the downward pressing device 2, and sliding bars 24 are slidably installed inside the guide bars 23. One end of the multiple sliding bars 24 is fixedly connected to the outer side of the downward pressing shaping block 3. The cooperation of the multiple guide bars 23 and the sliding bars 24 provides a guiding function for the lifting and lowering of the downward pressing shaping block 3.

[0028] Specifically, the foam itself is flammable, soft, and has low density, which makes it ineffective as a heating pad. Flame retardants, hardeners, and softeners are mixed into the foam material base material, so that the mixed foam material achieves flame retardancy and strong tensile strength. When the downward pressure shaping block 3 is raised and lowered, one end of the sliding bar 24 is simultaneously raised and lowered inside the guide bar 23, providing guidance for the raising and lowering of the downward pressure shaping block 3, thereby avoiding the raising and lowering of the downward pressure shaping block 3 and the tilting of the downward pressure shaping block 3, thereby affecting the downward pressure on the foam material.

[0029] like Figure 5-7 As shown, a telescopic shaft 32 and a plurality of oil-transmitting metal hoses 33 are fixedly installed above the downward-pressing shaping block 3, a downward-pressing shaping plate 31 is fixedly installed below the downward-pressing shaping block 3, and a plurality of oil-transmitting metal hoses 221 are fixedly installed on both sides of the shaping panel 22. The upper ends of the plurality of oil-transmitting metal hoses 221 are hidden inside the downward-pressing device 2, and the upper ends thereof are connected to the heated oil storage tank 7. The upper ends of the plurality of oil-transmitting metal hoses 33 are connected to the heated oil storage tank 7, and the lower ends thereof extend through and into the interior of the downward-pressing shaping plate 31.

[0030] A steel sheet mold group 34 is fixedly installed below the downward pressure shaping plate 31. The steel sheet mold group 34 includes two mold strips 341 and multiple mold strips 342. The multiple mold strips 342 are located between the two mold strips 341. A panel groove 222 is opened inside the shaping panel 22. A fixing plate 223 is fixedly installed on the inner top of the panel groove 222. One end of multiple oil guide pipes 221 is connected to the inside of the panel groove 222.

[0031] A concave groove 3421 and a plurality of trapezoidal grooves 3422 are provided inside the second mold strip 342. The plurality of trapezoidal grooves 3422 are located on both sides of the concave groove 3421, and the plurality of trapezoidal grooves 3422 are located at the inner top of the concave groove 3421. The depth of the plurality of trapezoidal grooves 3422 is lower than the depth of the concave groove 3421. Filter plates 3423 are fixedly installed at the ends of the plurality of trapezoidal grooves 3422. A concave groove 3421 and a plurality of trapezoidal grooves 3422 are provided inside the first mold strip 341. The plurality of trapezoidal grooves 3422 in the first mold strip 341 are distributed on the same side of the first mold strip 341.

[0032] The hot oil in the hot oil tank 7 is heated and cooled, and the ... The bottom temperature of the steel sheet mold strip group 34 is first affected, and then the heat transfer oil enters the next group of mold strip 1 341 or mold strip 2 342 through the trapezoidal groove 3422 which is wide at first and narrow at last to achieve a heating effect. A filter plate 3423 is fixedly installed between the two corresponding trapezoidal grooves 3422. The filter plate 3423 can filter impurities in the heat transfer oil to extend the service life of the heat transfer oil. The heat transfer oil in the heated oil storage tank 7 can also enter the panel groove 222 through multiple oil guide pipes 221, and heat the fixed plate 223. After the heated heat transfer oil enters the panel groove 222, the unheated oil in the panel groove 222 is transported to the interior of the heated oil storage tank 7 through the corresponding oil guide pipe 221. Through the circulation heating function, the lower pressing surface of the lower pressing forming plate 31 and the bearing surface of the fixed plate 223 can achieve the high temperature environment required for downward pressing. The fine steel panel groove 222 and the high-precision steel sheet mold strip group 34 can make the foam material thinner and more precise.

[0033] like Figure 8-9 As shown, an open groove 11 is provided inside the conveying device 1, and a type wheel 61 is movably installed on the outer side of both ends of the rewinding roller 6. The type wheel 61 is slidably installed inside the open groove 11, and a plurality of knobs 12 are movably installed above the conveying device 1, and the knobs 12 are located directly above the corresponding open groove 11.

[0034] Both ends of the rewinding roller 6 are fixedly connected with a through shaft 63, one end of the through shaft 63 movably passes through the interior of the industrial wheel 61 and extends, and a rotating gear 62 is fixedly installed on the outside of the extended end of the through shaft 63. A meshing wheel 13 is movably installed inside the conveying equipment 1, and the meshing wheel 13 is engaged with the rotating gear 62. A fixed motor 14 is also fixedly installed inside the conveying equipment 1, and the fixed motor 14 is connected to a driving gear 141 through a shaft, and the driving gear 141 is engaged with the meshing wheel 13.

[0035] Specifically, the type wheel 61 can slide inside the opening groove 11. When the type wheel 61 fits the inner walls of the three sides of the opening groove 11, the knob 12 is rotated so that its lower end is against the type wheel 61, that is, the position of the rewinding roller 6 is fixed. At this time, the position of the rewinding roller 6 makes the rotating gear 62 engage with the meshing wheel 13, and the meshing wheel 13 engages with the driving gear 141. The fixed motor 14 can be driven by electricity to rotate the driving gear 141. The rotation of the driving gear 141 drives the meshing wheel 13, the rotating gear 62 and the through shaft 63 to continue to rotate. The rotation of the through shaft 63 drives the rewinding roller 6 to rotate, and then the foam material after being pressed down is rolled up, thereby realizing the coiling of the foam material.

[0036] Example 2: Figure 10-11 As shown, comparative example 1, wherein another embodiment of the present invention is: both ends of the rewinding roller 6 are fixedly connected with a through shaft 63, one end of the through shaft 63 movably passes through the interior of the industrial wheel 61 and extends, and one end of the through shaft 63 is fixedly installed with a pulley 1 65, and the interior of the conveying equipment 1 is also fixedly installed with a fixed motor 14, and the fixed motor 14 is connected to a driving gear 141 through a shaft, and the interior of the conveying equipment 1 is fixedly installed with a component plate 15, and a semi-arc groove 151 is opened through the interior of the component plate 15, and a meshing wheel 2 16 is movably installed inside the semi-arc groove 151, and a pulley 2 17 is fixedly installed on one side of the meshing wheel 2 16, and a conveyor belt 66 is installed around the outer side of the pulley 1 65, and the pulley 2 17 and the pulley 1 65 form a transmission connection through the conveyor belt 66.

[0037] A rotating motor 18 is fixedly installed inside the conveying equipment 1. The rotating motor 18 is fixedly connected to an L-shaped bar 181 through the output end. One end of the L-shaped bar 181 is fixedly connected to a sliding wheel 19. The sliding wheel 19 is movably installed in the semi-arc groove 151. The meshing wheel 2 16 is movably installed on the side of the sliding wheel 19. The output shaft of the rotating motor 18 and the fixed motor 14 are on the same axis.

[0038] Specifically, the front end of the telescopic member strip 64 is installed with the type wheel 61 by insertion or interlocking, and then the telescopic member strip 64 can drive the type wheel 61 to move inside the opening groove 11. The rotation of the rewinding roller 6 is achieved by the electric drive fixed motor 14. At this time, the driving gear 141 drives the meshing wheel 2 16, the pulley 2 17, the pulley 1 65 and the through shaft 63 to rotate, thereby driving the rewinding roller 6 to rewind. The conveyor belt 66 is always in a taut state. When the rewinding roller 6 rewinds the foam material after the downward pressure for the first time, the multi-layered material surrounding the outside of the rewinding roller 6 The diameter of the foam material is relatively large. At this time, the telescopic member strip 64 is in a fully contracted state, that is, the distance between the rewinding roller 6 and the multi-stage conveying roller group 5 is relatively close. When the rewinding roller 6 needs to be rewound, the multi-layer foam material on its outside is first unwound by reversing the rewinding roller 6. With the cooperation of the conveying plate 4 and the multi-stage conveying roller group 5, the multi-layer foam material originally on the outside of the rewinding roller 6 is unwound. At this time, one end of the foam material is fixed on the outside of the rewinding roller 6, and the conveying plate 4 and the multi-stage conveying roller group 5 slightly convey the foam material again to stretch the foam material at this time, and then pass through The driving of the rotating motor 18 causes the L-shaped bar 181 to drive the sliding wheel 19 to slide in an arc shape inside the semi-arc groove 151. At this time, the driving gear 141 rotates, that is, the sliding wheel 19 drives the meshing wheel 2 16 to move inside the semi-arc groove 151 toward the position of the pulley 1 65. At the same time, the telescopic member strip 64 extends to drive the type wheel 61 and the rewinding roller 6 and the pulley 1 65 to move, increasing the distance between the pulley 1 65 and the pulley 2 17 at this time, so that the conveyor belt 66 is always in a taut effect. When the rewinding roller 6 moves a distance away from the multi-stage conveying roller group 5, the rewinding roller 6 is rewound. And the foam material between the multi-stage conveying roller group 5 is stretched again. When the driving gear 141 drives the meshing wheel 2 16, the pulley 1 65 and the rewinding roller 6 to rotate for rewinding, the foam material on the outside of the rewinding roller 6 is stretched to form a multi-layer foam material roll with a smaller diameter and a smaller footprint. Through the arc movement of the meshing wheel 2 16, the meshing wheel 2 16 is always on the outside of the driving gear 141 and is always in meshing connection. At this time, the position of the fixed motor 14 is always fixed, avoiding frequent displacement of the fixed motor 14 and reducing the working accuracy and service life of the fixed motor 14.

[0039] The heat conducting oil in the heating oil storage tank 7 in this device can quickly heat up the temperature of the down-pressing shaping block 3 required for the down-pressing work, thereby reducing the standby time and improving the performance of the device. The spool of foam material is rolled up on the outside of the roll 6 and the roll of the multi-stage conveying roller 5 is rotated to move the spool of foam material to the outside of the roll 6.

[0040] The front end of the telescopic member strip 64 is installed with the type wheel 61 by insertion or interlocking, and then the telescopic member strip 64 can drive the type wheel 61 to move inside the opening groove 11. The rotation of the rewinding roller 6 is achieved by the electric drive fixed motor 14. At this time, the driving gear 141 drives the meshing wheel 2 16, the pulley 2 17, the pulley 1 65 and the through shaft 63 to rotate, thereby driving the rewinding roller 6 to rewind. The conveyor belt 66 is always in a taut state. When the rewinding roller 6 rewinds the foam material after the downward pressure for the first time, the multi-layer foam material surrounding the outside of the rewinding roller 6 The diameter of the material is large, and the telescopic member strip 64 is in a fully retracted state at this time, that is, the distance between the rewinding roller 6 and the multi-stage conveying roller group 5 is close. When the rewinding roller 6 is needed to rewind, the multi-layer foam material on its outside is unwound by reversing the rewinding roller 6. With the cooperation of the conveying plate 4 and the multi-stage conveying roller group 5, the multi-layer foam material originally on the outside of the rewinding roller 6 is unwound. At this time, one end of the foam material is fixed on the outside of the rewinding roller 6, and the conveying plate 4 and the multi-stage conveying roller group 5 slightly convey the foam material again to stretch the foam material at this time, and then the foam material is rewound by rotating. The drive of the rotating motor 18 causes the L-shaped bar 181 to drive the sliding wheel 19 to slide in an arc shape inside the semi-arc groove 151. At this time, the driving gear 141 rotates, that is, the sliding wheel 19 drives the meshing wheel 2 16 to move inside the semi-arc groove 151 toward the position of the pulley 1 65. At the same time, the telescopic member strip 64 extends to drive the type wheel 61 and the rewinding roller 6 and the pulley 1 65 to move, increasing the distance between the pulley 1 65 and the pulley 2 17 at this time, so that the conveyor belt 66 is always in a taut effect. When the rewinding roller 6 moves a distance away from the multi-stage conveying roller group 5, the rewinding roller 6 is rewound. The foam material between the meshing wheel 2 16 and the multi-stage conveying roller group 5 is stretched again. When the driving gear 141 drives the meshing wheel 2 16, the pulley 1 65 and the rewinding roller 6 to rotate for rewinding, the foam material on the outside of the rewinding roller 6 is stretched to form a multi-layer foam material roll with a smaller diameter and a smaller footprint. Through the arc movement of the meshing wheel 2 16, the meshing wheel 2 16 is always on the outside of the driving gear 141 and is always in meshing connection. At this time, the position of the fixed motor 14 is always fixed, avoiding frequent displacement of the fixed motor 14 and reducing the working accuracy and service life of the fixed motor 14.
