Description

Technical Field

[0001] The utility model relates to the technical field of sheet molding compound production, in particular to an automatic pasting mechanism for sheet molding compound. Background Technique

[0002] Sheet molding compound, abbreviated as SMC, is a kind of sheet molding compound. SMC is a kind of sheet molding compound made by impregnating fiber or chopped fiber mat with resin paste and covering both sides with polyethylene film. A Chinese patent discloses a device for evenly pasting sheet molding compound (patent number: CN201921703671.9), which includes a frame and a conveyor belt arranged on the frame. A lower die pasting mechanism is arranged behind the conveyor belt along its conveying direction. A chopper, an upper film pasting mechanism and a pressing roller mechanism are arranged in sequence above the conveyor belt along its conveying direction. Both the lower die pasting mechanism and the upper film pasting mechanism include pasting components.

[0003] This technical solution cooperates with continuously extruding the resin paste from the discharge port. Moreover, due to the extrusion force between the elastic part and the stopper, the resin paste will not accumulate at the discharge port, realizing the automatic pasting of the film and reducing the manual labor. However, this solution still has deficiencies. When using the elastic part to extrude the material, the elastic part is very easy to stick with the resin paste, which will affect the continuous operation of the equipment. There is no simple disassembly device for cleaning or replacement, and the efficiency is low. Moreover, when pasting the resin paste, it needs to be at a certain high temperature to be more easily attached to the product to be pasted. This solution lacks a corresponding constant temperature maintaining device, which will affect the pasting effect. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment: Please refer to Figures 1-3 , the present invention provides a technical solution: an automatic pasting mechanism for a sheet molding compound, including a frame 1, a lower film conveying roller 2 is arranged at the top of the frame 1, a lower storage mechanism is arranged on the right side of the lower film conveying roller 2, a chopper 3 is arranged on the right side of the lower storage mechanism, a conveyor belt 4 is arranged below the chopper 3, an upper storage mechanism is arranged on the right side of the chopper 3, an upper film conveying roller 5 is arranged on the right side of the upper storage mechanism, a pressing roller mechanism is arranged below the upper film conveying roller 5, a cutting mechanism is arranged on the right side of the upper film conveying roller 5, and a winding drum 6 is arranged on the right side of the cutting mechanism.

[0021] Among them, as Figure 1 , Figure 2 andFigure 3 As shown in the figure, the upper material storage mechanism includes a material storage box 7. An electric heating sleeve 8 is arranged in the inner cavity of the material storage box 7. A fixing ring 9 is arranged in the inner cavity of the electric heating sleeve 8. A clamping strip 10 is arranged on the inner wall of the fixing ring 9. An elastic member 11 is arranged on the outer wall of the fixing ring 9. A first rotating shaft 12 is arranged in the inner cavity of the fixing ring 9. A connecting rod 13 is arranged on the outer wall of the first rotating shaft 12. A fixing block 14 is arranged on the inner wall of the fixing ring 9. A feed inlet 15 is arranged at the front end of the material storage box 7. A discharge outlet 16 is arranged on the outer wall of the material storage box 7.

[0022] When automatically pasting, it is necessary to paste both the upper and lower surfaces, there are problems of uneven feeding and difficulty in controlling the feeding thickness, and the resin paste needs to be maintained at a certain high temperature to make feeding and discharging easier. The existing equipment lacks a corresponding temperature maintenance mechanism, which affects the working efficiency. In this embodiment, as Figure 2 and Figure 3 shown, when the equipment is working, rotate the first rotating shaft 12, so that the first rotating shaft 12 drives the connecting rod 13 to rotate, thereby causing the fixing ring 9 thereon to rotate accordingly. Further, it will drive the elastic member 11 to rotate in the inner cavity of the material storage box 7. The elastic member 11 will extrude the pasting material in its inner cavity, and finally extrude it from the discharge outlet 16 to paste the film surface, achieving the purpose of uniform feeding. While rotating and extruding the material for discharging, turn on the electric heating sleeve 8 to heat the pasting material in the inner cavity of the material storage box 7, so that it can be maintained at a certain high temperature, making feeding and discharging easier, and it can also be more easily attached to the molding compound when pasting. When pasting with different thicknesses, replace the elastic members 11 with different corresponding widths, which will increase the gap between the elastic member 11 and the electric heating sleeve 8. When rotating and discharging the material, the feeding thickness will be increased, achieving the purpose of controlling the feeding thickness.

[0023] Among them, the pressing roller mechanism includes a pressing roller 17. A second rotating shaft 18 is arranged in the inner cavity of the pressing roller 17. The pressing roller mechanism is provided with a plurality of pressing rollers 17 and second rotating shafts 18.

[0024] In this embodiment, as Figure 2 and Figure 3 shown, after pasting both the upper and lower surfaces of the molding compound, it is necessary to compact the film. When it moves forward through the conveyor belt 4 and passes through the pressing roller 17, a plurality of pressing rollers 17 will rotate in the opposite direction of the conveying direction along the second rotating shaft 18 to compact the film multiple times, so that the pasting material is completely adhered to the molding compound, achieving the purpose of compaction.

[0025] Among them, the cutting mechanism includes a lifting rod 19. An installation plate 20 is arranged at the top of the lifting rod 19. A cutting blade 21 is arranged at the bottom of the installation plate 20. The cutting blade 21 is horizontally located above the molding compound.

[0026] After pasting and compacting the product, it needs to be sorted and collected. The existing equipment does not cut it during winding, and subsequent refinement of the quantity is required, resulting in increased working costs and reduced efficiency. In this embodiment, as Figure 2 shown, after compacting the molding compound, the winding drum 6 is used for winding. When the required amount is wound, the lifting rod 19 can be activated to move the lifting rod 19 downward, thereby causing the mounting plate 20 to move downward, and further driving the cutting blade 21 to move downward accordingly, so as to cut the product and complete the collection.

[0027] Among them, the structures of the upper storage mechanism and the lower storage mechanism are the same, but the positions of the feed port 15 and the discharge port 16 and the movement direction of the first rotating shaft 12 are exactly opposite to each other.

[0028] In this embodiment, as Figure 2 shown, the upper and lower surfaces of the molding compound can be evenly pasted, and then compacted to complete the pasting.

[0029] Among them, a clamping groove is formed on the fixing block 14, and the elastic member 11 is connected to the fixing block 14 through the clamping groove and the clamping strip 10.

[0030] When extruding and discharging, the internal components are very likely to be adhered with resin paste, which will affect the continuous operation of the equipment. There is no simple disassembly device during cleaning or replacement, resulting in problems affecting the subsequent use of the equipment. In this embodiment, as Figure 2 and Figure 3 shown, a clamping groove is formed on the clamping strip 10, and the elastic member 11 is connected to the fixing block 14 through the clamping groove and the clamping strip 10. After a period of time, the elastic member 11 can be removed from the clamping groove for complete cleaning to ensure subsequent use. The disassembly and installation are relatively fast. When pasting with different thicknesses, different widths of elastic members 11 can also be replaced through the clamping groove, achieving the purpose of easy use.

[0031] Working principle: When the device is working, rotate the first rotating shaft 12, so that the first rotating shaft 12 drives the connecting rod 13 to rotate, and thus the fixing ring 9 on it also rotates accordingly. Further, it will drive the elastic member 11 to rotate in the inner cavity of the material storage box 7. The elastic member 11 will extrude the pasting material in its inner cavity, and finally extrude it from the discharge port 16 to paste the upper surface of the film; while performing rotary extrusion for discharging, turn on the electric heating sleeve 8 to heat the pasting material in the inner cavity of the material storage box 7 to maintain it at a certain high temperature, which can make the feeding and discharging easier and also make it easier to adhere to the molding compound during pasting; the structures of the upper material storage mechanism and the lower material storage mechanism are the same, but the positions of the feeding port 15, the discharge port 16 and the movement direction of the first rotating shaft 12 are just opposite, which can evenly paste the lower surface of the molding compound; after pasting the upper and lower surfaces of the molding compound, it is necessary to compact the film. When it moves forward through the conveyor belt 4 past the pressing rollers 17, the plurality of pressing rollers 17 will rotate in the opposite direction to the conveying direction along the second rotating shaft 18 to compact the film multiple times, so that the pasting material is completely attached to the molding compound to achieve the purpose of compaction; finally, use the winding drum 6 for winding. When the required amount is wound, the lifting rod 19 can be started to make the lifting rod 19 move downward, so that the mounting plate 20 moves downward, and further the cutting blade 21 will also move downward accordingly, so as to cut the product and complete the collection; when pasting with different thicknesses, only need to replace the elastic member 11 with different corresponding widths.

[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
