Description

Technical Field

[0001] This utility model relates to the field of sponge processing technology, specifically to a shaping and extrusion device for sponge processing. Background Technology

[0002] A sponge shaping and extrusion equipment is a type of machinery used to produce sponge products. It primarily uses extrusion molding of sponge materials to meet various product requirements. This equipment typically includes the following main components: a feeding system: feeding raw materials (such as polyurethane sponge) into the extruder; an extruder: heating and extruding the sponge material using a screw or piston; a die: a die designed according to the product's shape and size, used to shape the extruded sponge; a forming system: using forming rollers to press the freshly formed sponge into the required shape; a cooling system: cooling the extruded sponge to maintain its shape and properties; and a cutting system: cutting the formed sponge into the required size and shape.

[0003] Existing sponge processing shaping and extrusion equipment, i.e., molding systems, typically use two molding rollers that can rotate in opposite directions simultaneously to extrude sponge sheets to shape them. Before shaping and extrusion, the sponge sheets need to be heated to make them soft and malleable. The sponge cannot be heated at the same time as shaping and extrusion, resulting in low processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a shaping and extrusion device for sponge processing. The shaping and extrusion device for sponge processing disclosed in this invention has a steam supply component connected to the end of a hollow shaping roller with good heat transfer effect. While the sponge is being extruded and shaped, the steam heats the shaping roller to soften the sponge, making it more soft and malleable. The extruded and shaped sponge has a better molding effect, is less prone to rebound, and has high processing efficiency, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a shaping and extrusion device for sponge processing, comprising a mounting frame, two shaping rollers mounted on the inner side wall of the mounting frame, the shaping rollers being hollow with a hollow end tube welded to the right end axial opening, the hollow end tube extending through the mounting frame and having a limiting rotating ring welded to the outer side wall of its end, a rotating seat detachably mounted on the outer side wall of the mounting frame corresponding to the limiting rotating ring, the limiting rotating ring being rotatably connected to the inner side wall of the rotating seat, and a steam supply assembly connected to the air inlet at the axial center of the rotating seat via a steam pipe and a steam valve.

[0006] Preferably, the left ends of the two shaping rollers are welded with drive shafts and are rotatably connected to the inner side wall of the mounting frame via the drive shafts. Gears are locked and installed on the outer side walls of the two drive shafts, and the two gears are meshed with each other.

[0007] Preferably, the power input end of the lower gear is connected to the power output end of the electric motor.

[0008] Preferably, the steam supply assembly includes a water tank mounted on the bottom of the mounting bracket, and a heating assembly is installed inside the water tank.

[0009] Preferably, the shaping roller is made of a metal material with good heat transfer effect, the drive shaft is made of a metal material with poor heat transfer effect, and the water tank is an insulated water tank.

[0010] Preferably, mounting plates are welded to both the left and right sides of the outer wall of the rotating seat, and the mounting plates and bolts are used to detachably install the rotating seat onto the outer wall of the mounting frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The sponge processing shaping and extrusion equipment disclosed in this utility model has a steam supply component connected to the end of a hollow shaping roller with good heat transfer effect. While the sponge is being extruded and shaped, the steam heats the shaping roller to soften the sponge, making it more flexible and malleable. The extruded and shaped sponge has a better forming effect, is less prone to rebound, and has high processing efficiency. This solves the problem that existing sponge processing shaping and extrusion equipment, i.e., molding systems, usually use two forming rollers that can rotate in opposite directions at the same time to extrude the sponge sheet to shape it. Before shaping and extrusion, the sponge sheet needs to be heated to make it soft and malleable. It is not possible to heat the sponge at the same time as shaping and extrusion, resulting in low processing efficiency. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 The figure shows a sponge processing shaping and extrusion device, including a mounting frame 1. Two shaping rollers 2 are installed on the inner wall of the mounting frame 1. The shaping rollers 2 are hollow and have a hollow end tube 12 welded to the right end shaft opening. The hollow end tube 12 passes through the mounting frame 1 and has a limiting ring 13 welded to the outer wall of its end. A rotating seat 14 is detachably installed on the outer wall of the mounting frame 1 at the corresponding limiting ring 13. The inner wall of the rotating seat 14 is rotatably connected to the limiting ring 13. The air inlet at the shaft of the rotating seat 14 is connected to a steam supply component through a steam pipe 8 and a valve 7. The sponge processing shaping and extrusion device disclosed in this utility model has a steam supply component connected to the end of the hollow shaping rollers 2 with good heat transfer effect. While the sponge is being squeezed and shaped, the shaping rollers 2 are heated and softened by steam, making the sponge softer and more malleable. The sponge after extrusion and shaping has a better forming effect, is less prone to rebound, and has high processing efficiency.

[0020] Furthermore, the left ends of the two shaping rollers 2 are welded with drive shafts 3 and are rotatably connected to the inner wall of the mounting frame 1 through the drive shafts 3. Gears 4 are locked and installed on the outer walls of the two drive shafts 3, and the two gears 4 are meshed with each other for easy transmission. Furthermore, the power input end of the lower gear 4 is connected to the power output end of the motor 5 for easy driving. Furthermore, the steam supply component includes a water tank 6 installed at the bottom of the mounting frame 1, and a heating component 11 is installed inside the water tank 6 for easy steam supply. Furthermore, the shaping rollers 2 are made of metal with good heat transfer effect, the drive shafts 3 are made of metal with poor heat transfer effect, and the water tank 6 is an insulated water tank, which facilitates heating and softening the sponge sheet while shaping and extruding the sponge sheet to make it easier to form. Furthermore, the left and right sides of the outer wall of the rotating seat 14 are welded with mounting pieces 9 and can be detachably installed on the outer wall of the mounting frame 1 through the mounting pieces 9 and bolts 10, so that the rotating seat 14 does not rotate with the shaping rollers 2.

[0021] In this solution, during use, the sponge processing shaping and extrusion equipment disclosed in this utility model is connected to a steam supply component at the end of the hollow shaping roller 2, which has a good heat transfer effect. This allows the sponge to be heated and softened by steam while being extruded and shaped, making it more flexible and malleable. The extruded and shaped sponge has a better forming effect, is less prone to rebound, and has high processing efficiency. First, an appropriate amount of water is added to the water tank 6. An external power supply is used to turn on the heating component 11, the air valve 7, and the motor 5 via an external switch. After the heating component 11 heats the water, the steam in the upper part of the water tank 6 flows into the hollow shaping roller 2 through the air valve 7, the steam pipe 8, and the hollow end pipe 12. The steam first heats the hollow shaping roller 2, while the motor 5 drives the lower gear 4 and the lower shaping roller 2 to rotate counterclockwise. Because the lower gear... The upper gear 4 is meshed with the upper part of the wheel 4. The upper gear 4 and the upper shaping roller 2 rotate clockwise. When the shaping roller 2 rotates, the hollow end tube 12 at the end of the shaping roller 2 is rotatably connected to the inner wall of the rotating seat 14 through the limiting rotating ring 13. The rotating seat 14 can be detachably installed on the outer wall of the mounting frame 1. Thus, the rotating seat 14 and the steam pipe 8 do not rotate with it, but can supply steam smoothly. The sponge sheet to be extruded and shaped is inserted between the two shaping rollers 2. The sponge sheet is slowly formed by the two shaping rollers 2. At the same time, the two shaping rollers 2 heat the sponge sheet while extruding and shaping it, making it softer and easier to shape. After the sponge sheet is extruded and shaped, it is not easy to rebound after cooling. The forming efficiency is high and the forming quality is high (the motor 5, the air valve 7 and the heating component 11 are all existing products on the market).
