Description

[0001] The invention belongs to the technical field of sheet material production equipment, and in particular relates to sheet material production equipment and a production process. Background Art

[0002] The sheet material is made of resin or resin as the main component during the processing, with plasticizers, fillers, lubricants, colorants and other additives as auxiliary components. It is a material that can flow and form during the processing.

[0033] The present invention generates an electromagnetic effect through the electromagnets arranged inside the electromagnetic positioning assembly, so that the central magnetic axis is suspended. During the rolling process of the sheet, if it is necessary to adjust the distance between adjacent magnetic suspension rollers, it is necessary to change the magnitude of the current passing through the electromagnetic coil, thereby reducing the suspension stability of one of the magnetic axes. At this time, the axis center of a single magnetic axis can be deviated below the axis center of the magnetic suspension roller, thereby increasing the distance between adjacent magnetic suspension rollers.

[0034] In the present invention, since the magnetic suspension roller is suspended by electromagnetic means, there is a certain gap between the magnetic suspension roller and the fixed sleeve and the electromagnetic positioning component, so it has a certain elastic buffer space. When a sheet rolled between two adjacent magnetic suspension rollers has a local bulge, it can be rolled by multiple groups of adjacent magnetic suspension rollers to gradually flatten the bulge evenly.

[0050] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0051] See attached Figure 1 A sheet material production equipment comprises a mixer 1, which conveys the material to the inside of a mixer 3 through a screw conveyor 2, and the mixer 3 conveys the mixed material to the inside of an extruder 4 through the screw conveyor 2 thereafter. The extruder 4 calenders and extrude the material and conveys it from a discharge end to an immersion tank 5 for cooling and forming, and then dries and heats the extruded material through a drying and heating machine 6, until it is conveyed to a rolling device 7, and the extruded material is rolled to a desired thickness by the rolling device 7, and is wound up by a winder 8 thereafter.

[0052] like Figure 8 As shown, the sheet production equipment includes the following process steps during the production process:

[0053] S1: Mixing, by adding the sheet production raw materials into the mixer 1, performing preliminary mixing in the mixer 1, and discharging through the discharge port;

[0054] S2: Screw conveying, the preliminary mixed raw materials output through the S1 outlet are conveyed from the feed end to the discharge end, and the sheet production raw materials are further mixed during the conveying process of the screw conveyor 2;

[0055] S3: stirring, the mixed raw materials outputted from the discharge end of S1 are fed into the mixer 3, and are stirred by the mixer 3 to mix the materials evenly, and the discharge valve on the bottom side is opened for output, and the output is started to S4;

[0056] S4: Screw conveying, the material is conveyed and further stirred by the screw conveyor 2 arranged after the mixer 3;

[0057] S5: extrusion, extruding the stirred raw material through S4, extruding the raw material into a sheet through the extruder 4, and outputting;

[0058] S6: Immersing in water for cooling and shaping. Since the sheet material outputted from S5 has a certain temperature and impurities or sticky substances on the outside of the sheet material are avoided, the sheet material outputted from S5 is initially cooled and cleaned by the immersion tank 5 and outputted through the roller shaft.

[0059] S7: Drying and heating: after the sheet material is processed in S6, it is dried by a drying and heating machine 6 and heated to a certain temperature to facilitate further calendering and output of the sheet material;

[0060] S8: Hot pressing, flattening and shaping, can also refer to Figure 2 As the material is inputted in S7, the sheet material can be pressed to the required thickness by the multiple groups of magnetic suspension rollers 701 inside the rolling device 7, so as to achieve the flattening and shaping of the sheet material;

[0061] S9: cutting and trimming, cutting the sheet material to a certain width by a cutter arranged at the output end of the roller pressing device 7, thereby trimming and shaping the sheet material;

[0062] S10: Rewinding: Rewinding the sheet outputted from S9 to complete the production and processing of the sheet.

[0063] In the process of using the roller pressing device 7, since the existing roller pressing equipment cannot be adjusted or is difficult to adjust, the present embodiment 1 is proposed:

[0064] like Figure 2 and Figure 3 As shown, a plurality of magnetic suspension rollers 701 for rolling materials are provided in the middle of the rolling device 7, and an output roller 703 is provided at the output end of the rolling device 7. The output roller 703 is installed at the output end of the rolling device 7 through positioning parts 702 provided at both ends, and a driving motor assembly 704 for providing rotational power to the output roller 703 is provided on the outer side of the positioning part 702.

[0065] Among them, a magnetic shaft 7014 is penetrated through the middle of the magnetic suspension roller 701, and a connecting positioning part 7017 for supporting the magnetic suspension roller 701 is sleeved in the middle of the magnetic shaft 7014. Electromagnetic positioning components 7011 are inserted into the two ends of the magnetic suspension roller 701. The electromagnetic positioning component 7011 cooperates with the magnetic gap between the internally arranged electromagnet 7020 and the magnetic shaft 7014. The electromagnetic positioning component 7011 is threadedly installed on the inner side of the rolling device 7 on both sides.

[0066] In addition, a plurality of arc-shaped support plates 7018 are provided on the outer side of the connection and positioning portion 7017 through a connecting rod, and the outer side of the support plates 7018 presses against the inner side of the magnetic suspension roller 701 .

[0067] The arc-shaped support plate 7018 is used to support the inner side of the magnetic suspension roller 701 and to position the magnetic suspension roller 701. During the rotation of the magnetic suspension roller 701, the arc-shaped support plate 7018 can support the inner side of the magnetic suspension roller 701 to avoid deformation of the magnetic suspension roller 701, thereby increasing the strength of the magnetic suspension roller 701 to a certain extent.

[0068] Furthermore, spherical grooves 7025 are provided at both ends of the magnetic shaft 7014 , and positioning plates 7013 are provided at both ends of the magnetic suspension roller 701 and extend inside the rolling device 7 , and hemispherical magnetic connection balls 7015 are provided inside the positioning plates 7013 .

[0069] According to the above structure, and referring to Figure 3 and Figure 4 The electromagnetic positioning components 7011 on both sides are installed on the inner side of the rolling devices 7 on both sides through a plurality of positioning bolts 7012, and the other ends of the positioning bolts 7012 are fixedly installed with positioning plates 7013 through nuts.

[0070] Furthermore, a plurality of mounting screw holes 7023 for threaded connection with the positioning bolts 7012 are provided on the side of the electromagnetic positioning component 7011 , and a positioning socket 7024 corresponding to the plurality of positioning bolts 7012 is provided on the surface of the positioning plate 7013 .

[0071] The electromagnetic positioning assembly 7011 is fixed by the rolling device 7 and the positioning bolts 7012, and an electromagnetic effect is generated by the electromagnet 7020 arranged inside the electromagnetic positioning assembly 7011. Then, after the electromagnetic coil 7021 on the electromagnet 7020 is energized, a magnetic field is generated inside the annular electromagnet 7020, and the magnetic axis 7014 in the middle is suspended.

[0072] Reference Figure 4 and Figure 5A fixed sleeve 7019 is provided on the opposite side of the two electromagnetic positioning components 7011. The fixed sleeve 7019 is clearance-matched with the inner side of the magnetic suspension roller 701. The electromagnet 7020 is fixedly arranged on the inner side of the fixed sleeve 7019, and the electromagnet 7020 is evenly distributed in a circular array.

[0073] Furthermore, an electromagnetic coil 7021 is wound around the outside of the electromagnet 7020, and multiple groups of electromagnetic coils 7021 on the outside of the electromagnet 7020 are connected end to end. The ends of the multiple groups of electromagnetic coils 7021 are inserted into the wire jack 7022 set on the side of the electromagnetic positioning component 7011 and connected to the power system inside the rolling device 7.

[0074] According to the above structure, when the magnetic axis 7014 is in the suspension process, the magnetic axis 7014 and the electromagnet 7020 are in a suspended state, and the magnetic suspension roller 701 is also in a suspended state with the fixed sleeve 7019. At this time, after a sheet is wrapped around the outside of the magnetic suspension roller 701, during the rolling process of the sheet, if it is necessary to adjust the spacing between adjacent magnetic suspension rollers 701, it is necessary to change the current of the electromagnetic coil 7021, thereby reducing the suspension stability of one of the magnetic axes 7014. At this time, the axis center of a single magnetic axis 7014 can be deviated below the axis center of the magnetic suspension roller 701, thereby increasing the spacing between adjacent magnetic suspension rollers 701.

[0075] Among them, in order to increase and decrease the electromagnetic strength of the electromagnet 7020, the current passing through the electromagnetic coil 7021 is controlled by the power system, and the power system includes a controller, a power module, a sensor and a power amplifier. Since adjusting the magnetic strength of the electromagnet 7020 is an existing technology, it will not be elaborated on.

[0076] Embodiment 2:

[0077] As in the technical solution of the first embodiment, the magnetic magnitude is adjusted by adjusting the current magnitude of the electromagnetic coil 7021, thereby realizing the rolling distance between two adjacent magnetic suspension rollers 701, which is used to control the thickness of the sheet. When the current of the electromagnetic coil 7021 becomes smaller, the lateral position of the magnetic axis 7014 will be unstable. Therefore, this embodiment is proposed:

[0078] like Figure 4 , Figure 6 and Figure 7 As shown, a positioning and pressing assembly 7016 is rotatably installed inside the spherical groove 7025 , and the positioning and pressing assembly 7016 is magnetically and slidably installed on the outside of the magnetic connection ball 7015 .

[0079] In addition, the positioning magnetic axis 7014 is elastically clamped between the positioning plates 7013 on both sides through the positioning pressing assembly 7016 .

[0080] Please refer to the attached Figure 7 The positioning and pressing assembly 7016 includes an extrusion head 70161 at the end, one end of the extrusion head 70161 is set to a hemispherical shape, and the other end of the extrusion head 70161 is integrally formed with an outer sleeve 70162, and the other end of the outer sleeve 70162 is slidably inserted with an inner rod 70163 inside, and the other end of the inner rod 70163 is provided with a magnetic connection end 70164, and the end of the magnetic connection end 70164 facing away from the inner rod 70163 is provided with a spherical groove 70165 for adapting to the outside of the magnetic connection ball 7015, and a spring 70166 is fixedly connected between the magnetic connection end 70164 and the extrusion head 70161, and the spring 70166 is sleeved on the outside of the outer sleeve 70162.

[0081] Among them, the extrusion head 70161 is pressed against the inside of the spherical groove 7025 by the spring 70166.

[0082] The extrusion heads 70161 at the ends of the positioning and pressing assemblies 7016 on both sides squeeze the spherical grooves 7025 at both ends of the magnetic axis 7014, so that the magnetic axis 7014 can be positioned, and horizontal movement of the magnetic axis 7014 can be avoided during the up and down movement. A spring 70166 is sleeved in the middle of the positioning and pressing assemblies 7016, and the sliding connection between the outer sleeve 70162 and the inner rod 70163 is cooperated, so that during the vertical movement of the magnetic axis 7014, the positioning and pressing assemblies 7016 can flexibly squeeze the magnetic axis 7014, and because of the magnetic sliding connection between the spherical groove 70165 and the magnetic connecting ball 7015, one end of the positioning and pressing assemblies 7016 can slide around the surface of the magnetic connecting ball 7015, and the other end can be continuously pressed inside the spherical groove 7025.

[0083] In addition, when the magnetic shaft 7014 and the electromagnet 7020 are not turned on, the outer side of the magnetic shaft 7014 is supported by the inner side of the electromagnetic positioning assembly 7011, so that the outer side of the magnetic shaft 7014 and the inner side of the electromagnet 7020 always maintain a clearance fit state.

[0084] Combining the first and second embodiments, during use, since the magnetic suspension roller 701 is suspended by electromagnetic means, there is a certain gap between the magnetic suspension roller 701 and the fixed sleeve 7019 and the electromagnetic positioning assembly 7011, and thus it has a certain elastic buffer space. When a sheet rolled between two adjacent magnetic suspension rollers 701 has a local bulge, it can be rolled by multiple groups of adjacent magnetic suspension rollers 701 to gradually flatten the bulge evenly.

[0085] The working principle of the present invention is:

[0086] The electromagnetic positioning assembly 7011 is fixed by the rolling device 7 and the positioning bolts 7012, and the electromagnetic effect is generated by the electromagnet 7020 arranged inside the electromagnetic positioning assembly 7011. Then, after the electromagnetic coil 7021 on the electromagnet 7020 is energized, a magnetic field is generated inside the annular electromagnet 7020, and the magnetic axis 7014 in the middle is suspended;

[0087] By adjusting the electromagnetic strength of the electromagnet 7020 to increase or decrease, the axis of a single magnetic axis 7014 can be deflected below the axis of the magnetic suspension roller 701, thereby increasing the spacing between adjacent magnetic suspension rollers 701, and cooperating with the positioning and pressing components 7016 on both sides to achieve the positioning of the magnetic axis 7014;

[0088] The magnetic suspension roller 701 is suspended by electromagnetic means. There is a certain gap between the magnetic suspension roller 701 and the fixed sleeve 7019 and the electromagnetic positioning component 7011, so that it has a certain elastic buffer space. When the sheet rolled between two adjacent magnetic suspension rollers 701 has local bulges, it can be rolled by multiple groups of adjacent magnetic suspension rollers 701.

[0089] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.

9. A sheet production process, for using the sheet production device according to any one of claims 1 to 8, Features: The process steps include: S1: Mixing, by adding the raw materials for sheet production into the mixer (1), Preliminary mixing and discharge through the discharge port; S2: Screw conveying, the preliminary mixed raw materials output through the S1 outlet are conveyed from the feed end to the discharge end, and the sheet production raw materials are further mixed during the conveying process of the screw conveyor (2); S3: stirring, the mixed raw materials outputted from the discharge end of S1 are fed into the mixer (3), and are stirred by the mixer (3) to mix the materials evenly, and the discharge valve on the bottom side is opened for output, and the output is started to S4; S4: screw conveying, the material is conveyed and further stirred by a screw conveyor (2) arranged behind the mixer (3); S5: extrusion, extruding the stirred raw material through S4, extruding the raw material into a sheet through an extruder (4), and outputting; S6: Immersing in water for cooling and shaping. Since the sheet material outputted from S5 has a certain temperature and impurities or sticky substances on the outside of the sheet material are avoided, the sheet material outputted from S5 is initially cooled and cleaned through the immersion tank (5) and then outputted through the roller. S7: Drying and heating: after the flake material is processed in S6, it is dried by a drying and heating machine (6), heated to a certain temperature and output; S8: hot pressing, flattening and shaping. As the material is input in S7, the sheet material can be pressed to a desired thickness through the extrusion of multiple groups of magnetic suspension rollers (701) inside the rolling device (7), thereby achieving flattening and shaping of the sheet material. S9: cutting and trimming, using a cutter provided at the output end of the roller pressing device (7) to cut the sheet material to a certain width, thereby trimming and shaping the sheet material; S10: Rewinding: Rewinding the sheet outputted from S9 to complete the production and processing of the sheet.
