Description

Technical Field

[0001] This utility model relates to the field of sound insulation cotton production technology, and in particular to a three-dimensional molding equipment for fiber-reinforced sound insulation cotton. Background Technology

[0002] In modern industry and construction, the demand for sound insulation materials is increasing. Fiber-reinforced sound insulation cotton, due to its excellent sound insulation and noise reduction performance, is widely used in industries such as automobile manufacturing, rail transportation, and building decoration. Traditional sound insulation cotton molding equipment suffers from problems such as uneven glue application, discontinuous glue supply, and unstable pressing effect during the production process.

[0003] For example, a double-sided laminating device for forming sound and heat insulation cotton, disclosed on the China Patent Network, has the patent publication number "CN219883463U". This device mainly consists of a base plate with a middle rubber feeding component at one end, an upper felt feeding component located on one side of the middle rubber feeding component on the upper surface of the base plate, a lower felt feeding component symmetrical to the upper felt feeding component at the bottom of the base plate, a pressing component located on one side of the upper felt feeding component on the upper surface of the base plate, and a discharge component at the other end of the base plate. The upper and lower felt are bonded to both sides of the rubber and pressed together by a pressing assembly to form sound and heat insulation cotton. The drive motor, through the first synchronous wheel, the second synchronous wheel, and the drive gear and driven gear, causes the upper and lower discharge rollers to continuously extract the pressed sound and heat insulation cotton, thereby reducing manual intervention. However, it is difficult to accurately control the amount and coverage of the adhesive sprayed on the felt by the rubber roller, and the felt may also stick to the rubber roller, resulting in poor adhesion and reduced sound insulation performance of the sound insulation cotton in subsequent use. To solve the above problems, this utility model proposes a brand-new three-dimensional molding equipment for fiber-reinforced sound insulation cotton. Utility Model Content

The two connecting blocks 26 are rotatably connected to a roller pressing shaft 22.

[0021] In this invention, the specific working principle of the device is as follows: First, the equipment is started, and line 1 begins to operate, conveying the sound insulation board. Simultaneously, line 1 drives the upper felt conveyor line 2 and the lower felt conveyor line 4 to operate synchronously. The lower felt conveyor line 4 conveys the felt to the area below the sound insulation board. Motor 3 is turned on, and its output shaft drives roller 5 to rotate. Roller 5 transmits power to the first rotating shaft 7 through synchronous belt 6. When the first rotating shaft 7 rotates, the first bevel gear 8 fixed on its axial outer wall rotates accordingly. The second bevel gear 9, which meshes with the first bevel gear 8, also begins to rotate, thereby driving the second rotating shaft 13 to rotate. The second rotating shaft 13 drives the reciprocating lead screw 14 to rotate. When the reciprocating screw 14 rotates, the screw sleeve 141, which is threaded to it, performs reciprocating linear motion on the reciprocating screw 14. The screw sleeve 141 is fixedly connected to the piston end of the piston cylinder 16, so the piston of the piston cylinder 16 performs reciprocating motion under the drive of the screw sleeve 141. The inlet pipe 18 and outlet pipe 17 of the piston cylinder 16 are both double-ended pipe structures, symmetrically arranged at both ends of the piston cylinder 16. This unique design, combined with the one-way valve inside the pipe, creates a highly efficient liquid transfer system. When the lead screw sleeve 141 drives the piston to reciprocate linearly within the piston cylinder 16, taking the piston moving to the right as an example, the space on the left side of the piston increases and the pressure decreases. At this time, the one-way valve in the left inlet pipe 18 opens, and the glue in the storage tank 19 enters the left side of the piston cylinder 16 through the left inlet pipe 18 under the action of pressure difference; while the one-way valve in the right outlet pipe 17 opens, and the glue on the right side of the piston cylinder 16 flows out through the right outlet pipe 17, entering the first spray pipe 171 and the second spray pipe 172 respectively, and finally being sprayed out from the first spray head 27 and the second spray head 28, realizing the glue application operation on the sound insulation board and the felt. When the piston moves to the left, the working principle is similar: the space on the right side of the piston increases, the pressure decreases, and the one-way valve in the right inlet pipe 18 opens, allowing glue to enter the right side of the piston cylinder 16; the one-way valve in the left outlet pipe 17 opens, and the glue on the left side of the piston cylinder 16 flows out through the left outlet pipe 17 and completes the spraying. In this way, no matter which direction the piston moves, the inlet pipe 18 can continuously deliver glue to the piston cylinder 16, and the outlet pipe 17 can stably output glue for coating, ensuring the continuity and stability of the coating process and providing a reliable glue supply for the molding of the sound insulation cotton. The first spray head 27 is fixed at the lower end of the line body 1 and sprays glue onto the upper surface of the sound insulation board; the second spray head 28 is fixed at the lower end of the upper felt conveyor line 2 and sprays glue onto the upper surface of the lower felt, completing the coating operation.

[0022] The upper felt conveyor line 2 transports the glued upper felt, which, together with the glued sound insulation board transported by line 1 and the glued felt below the sound insulation board transported by the lower felt conveyor line 4, converges at the pressing mechanism. The height of the collar 24 can be adjusted by rotating the adjusting screw 23, thus initially adjusting the downward pressing position of the roller 22. When the roller 22 moves downward and contacts the upper felt, the sound insulation board, and the lower felt, the return spring 251 inside the telescopic cylinder 25 acts as a damper. As pressing proceeds, if the pressure is too high, the return spring 251 will be compressed, and the telescopic end of the telescopic cylinder 25 will retract upward, reducing the downward pressure and preventing damage to the sound insulation board due to excessive pressing force. When the pressure decreases, the return spring 251 pushes the telescopic end of the telescopic cylinder 25 downward, maintaining a suitable pressing force to ensure tight pressing of the three components, ultimately forming a three-dimensional molded product of fiber-reinforced sound insulation cotton.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
