Description

Technical Field

[0001] This invention relates to the field of new materials technology, and in particular to a composite sponge and the feeding component in its conveying device. Background Technology

[0002] Composite sponge is a sponge structure composed of different materials, usually formed by layering two or more materials together. This sponge structure usually has various properties and functions, such as shock absorption, waterproofing, sound insulation, and heat insulation. Composite sponge is usually composed of sponge materials of different densities, thicknesses or types, such as polyurethane foam, rubber foam, memory foam, etc.

[0003] Polyurethane foam has good plasticity and shock absorption properties, and its cost is relatively low compared to other materials. However, it has many through-pores, which makes it easy for water to flow through and has poor water retention. Therefore, a composite foam with good water absorption and water retention properties is proposed.

[0004] The published patent document CN117126362A discloses a composite sponge and its feeding assembly in a conveying device. The feeding assembly is mounted on a frame near the drive roller and includes a guide plate and a support assembly. The upper part of the conveyor belt near the drive roller is the feeding section. The guide plate is fixed to the frame and positioned directly above the feeding section. This composite sponge exhibits high stability, and this feeding assembly improves the conveying stability of granular raw materials.

[0005] When using the above devices, although they can gather the fallen particles together for transportation, when facing the layering step, all materials must be shaped and layered according to the preparation mold. When the irregular polyurethane particles are transported into the mold at one time, these fallen particles are still relatively loose and are easily squeezed out when they enter the mold, ending up around the mold and causing some waste.

[0006] Therefore, this application proposes a feeding component in a composite sponge conveying device. Summary of the Invention

[0007] The purpose of this invention is to address the problem in the prior art where irregular polyurethane granules, when transported to a mold in a single operation, are still relatively loose and easily squeezed out when introduced into the mold. This invention proposes a composite sponge and the feeding component in its conveying device.

[0008] The technical solution of the present invention: a composite sponge, the composite sponge comprising a gel layer and a liquid absorbent layer, each having multiple layers, wherein the multiple liquid absorbent layers and the multiple gel layers are overlapped.

[0009] The liquid absorption layer is composed of polyurethane foam and polyvinyl alcohol foam within the mesh-like voids of the polyurethane foam. The composite foam has a hardness greater than 30HD. The volume of the polyvinyl alcohol foam accounts for 60-70% of the total volume of the liquid absorption layer, and the volume of the polyurethane foam accounts for 30-40% of the total volume of the liquid absorption layer.

[0010] The gel layer comprises a mixture of polymer gel and silicone.

[0011] A feeding component for a composite sponge raw material conveying device includes a conveying device support component, a guide component rotatably connected to the conveying device support component, a driving component disposed at one end of the guide component, the driving component being disposed on the surface of the conveying device support component, and a pressure component fixedly connected to the top end of the guide component.

[0012] The conveying device support assembly includes a long support plate, a conveyor belt is fixedly connected to the surface of the long support plate, a first clamping block is fixedly connected to one side of the long support plate, and a second clamping block is fixedly connected to the other side of the long support plate.

[0013] The guide assembly includes two rotating rods, which are rotatably mounted between the second holding block and the first holding block. The outer sides of the two rotating rods are fixedly connected with the same number of arc-shaped wall guide blocks, and one side of the arc-shaped wall guide block is an arc-shaped surface. A straight edge block is fixedly connected to the upper end of the arc-shaped surface of the arc-shaped wall guide block.

[0014] Optionally, the drive assembly includes two belts, one of which has a gear meshing with its inner side. The gear is fixedly connected to the outer side of a rotating rod, and one end of the rotating rod passing through the gear is fixedly connected to a positioning rod. The positioning rod is fixedly mounted on a first holding block.

[0015] Optionally, a blocking turntable is rotatably connected to one end of the first holding block, and an auxiliary gear is meshed with the outer side of the blocking turntable. The auxiliary gear is rotatably connected to the first holding block, and a forward and reverse motor is fixedly connected to the center of the first holding block. The output shaft of the forward and reverse motor is fixedly connected to one end of the blocking turntable, and a belt is meshed with the outer side of the blocking turntable.

[0016] Optionally, another belt is meshed with an auxiliary gear, and there are two such gears. The other belt is meshed with another gear, and the two gears are arranged to rotate in opposite directions.

[0017] Optionally, the guide assembly further includes a bidirectional toothed turntable, on the outer side of which two concave arc-shaped edges are fixedly connected. A toothed turntable is meshed with the outer side of the bidirectional toothed turntable. The concave arc-shaped edges are fitted with the arc-shaped edges of the toothed turntable. The toothed turntable is fixedly mounted on one end of a rotating rod. The bidirectional toothed turntable and the toothed turntable are rotatably connected to a second holding block. Two connecting rods are fixedly connected to one side of the elongated support plate. A mounting block is fixedly connected to the top of the connecting rod. The rotating rod is rotatably connected inside the mounting block.

[0018] Optionally, the pressure assembly includes an auxiliary rod rotatably connected between the second clamping block and the first clamping block. A blocking block is fixedly connected to the outer side of the auxiliary rod, a receiving block is fixedly connected to one side of the blocking block, an airbag block is fixedly connected to one side of the receiving block, a guide rod is fixedly connected to the top of the airbag block, a pressure plate is fixedly connected to the top of the guide rod, a bidirectional clamping block is fixedly connected to the inner wall of the receiving block, and the guide rod is slidably connected to the inner side of the bidirectional clamping block.

[0019] Compared with the prior art, the present invention has the following beneficial technical effects:

[0020] 1. When the polyurethane granules bounce outward during the transport process, they are subjected to the concave arc shape of the arc-shaped guide block. After the polyurethane granules are ejected onto the concave arc, they slide from the concave arc onto the conveyor belt. The arc shape of the two sets of arc-shaped guide blocks is greater than that, which expands the collection and blocking range of the polyurethane granules.

[0021] 2. A gear drives the arc-shaped guide block to rotate through the rotating rod connected to it until the straight edge block is perpendicular to the surface of the conveyor belt. Meanwhile, the blocking turntable drives the auxiliary gear to mesh and rotate. The auxiliary gear drives another gear to rotate through the rotating belt connected to it, which in turn drives the rotating rod connected to it to rotate in the opposite direction. During this process, some particles stuck on the arc-shaped guide block are thrown onto the conveyor belt due to the direction guided by the arc edge, thus better assisting in the collection of the bounced particles and reducing production costs.

[0022] 3. Under the extension and limitation of the airbag block, the pressure plate moves along the conveyor belt towards the side of the guide rod by gravity, held by the bidirectional clamping block, until it touches the sponge material. The pressure plate squeezes the sponge material by its own gravity, and at the same time, with the straight side block perpendicular to the conveyor belt, it squeezes the sponge material into a cuboid. The sponge material and the adhesive adhere to each other, so as to better cooperate in the next step of plasticization. Then, it enters the cuboid mold, which reduces the sponge material being discharged from the mold due to the large volume difference between the sponge material and the mold, and facilitates the production of composite sponge.

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example 1

[0032] like Figure 1 As shown, the present invention proposes a composite sponge, which includes a gel layer and a liquid absorbent layer, both of which are configured to have multiple layers, and the multiple liquid absorbent layers and the multiple gel layers are overlapped.

[0033] The liquid absorption layer consists of polyurethane foam and polyvinyl alcohol foam within the mesh-like pores of the polyurethane foam. The composite foam has a hardness greater than 30HD. The volume of the polyvinyl alcohol foam accounts for 60-70% of the total volume of the liquid absorption layer, while the volume of the polyurethane foam accounts for 30-40%. The polyurethane foam enhances the water adsorption capacity, and the polyvinyl alcohol foam fills the mesh-like pores of the polyurethane foam. Because the pores within the polyurethane foam are relatively smaller than those within the polyurethane foam itself, it has better adsorption properties for dirt and other substances, thus improving the high efficiency of the composite foam in daily life.

[0034] The gel layer is composed of a polymer gel and a silica gel mixture. The gel layer is used to adsorb the multi-layer liquid absorption layer layer by layer, thus avoiding the separation of the multi-layer gel layers. Example 2

[0035] like Figures 1-2 As shown, based on Embodiment 1, a feeding component for a composite sponge raw material conveying device includes a conveying device support component 1, a guide component 2 rotatably connected to the conveying device support component 1, a driving component 4 provided at one end of the guide component 2, the driving component 4 being disposed on the surface of the conveying device support component 1, and a pressure component 3 fixedly connected to the top end of the guide component 2.

[0036] The conveying device support assembly 1 includes a long support plate 101. A conveyor belt 102 is fixedly connected to the surface of the long support plate 101. A first clamping block 103 is fixedly connected to one side of the long support plate 101, and a second clamping block 105 is fixedly connected to the other side of the long support plate 101. The raw material of the composite sponge is normally conveyed to the next position through the conveyor belt mechanism on the surface of the conveyor belt 102.

[0037] In this embodiment, the guide component 2 includes two rotating rods 205, which are rotatably installed between the second holding block 105 and the first holding block 103. The same number of arc-shaped wall guide blocks 201 are fixedly connected to the outer side of the two rotating rods 205. One side of the arc-shaped wall guide block 201 is an arc-shaped surface, and a straight edge block 206 is fixedly connected to the upper end of the arc-shaped surface of the arc-shaped wall guide block 201. When the polyurethane granules are transported from the conveyor belt 102 to the next position, when the polyurethane granules bounce outward during the transport process, the bounced polyurethane granules are subjected to the concave arc of the arc-shaped wall guide block 201. After the polyurethane granules are ejected onto the concave arc, they slide from the concave arc onto the conveyor belt 102. The arc degree of the two sets of arc-shaped wall guide blocks 201 is greater than 120, which expands the collection and blocking range of the polyurethane granules. Example 3

[0038] like Figures 1-4As shown, based on the above embodiment 1 or 2, the drive assembly 4 includes two rotating belts 401. A gear 404 is meshed with the inner side of one rotating belt 401. The gear 404 is fixedly connected to the outer side of the rotating rod 205. One end of the rotating rod 205, passing through the gear 404, is fixedly connected to a positioning rod 406. The positioning rod 406 is fixedly mounted on a first holding block 103. One end of the first holding block 103 is rotatably connected to a blocking turntable 405. The outer side of the blocking turntable 405 is meshed with a... An auxiliary gear 407 is rotatably connected to a first holding block 103. A forward / reverse motor 402 is fixedly connected to the center of the first holding block 103. The output shaft of the forward / reverse motor 402 is fixedly connected to one end of a blocking turntable 405. One belt 401 is engaged with the outside of the blocking turntable 405, and another belt 401 is engaged with the auxiliary gear 407. There are two gears 404, and the other belt 401 is engaged with the other gear 404. Two gears 404 are set to rotate in opposite directions. The output shaft of the forward and reverse motor 402 drives the blocking turntable 405 to rotate. The blocking turntable 405 drives a conveyor belt 401 to transmit motion. The conveyor belt 401 drives a gear 404 to rotate. The gear 404 drives the arc-shaped wall guide block 201 to rotate through the rotating rod 205 connected to it until the straight edge block 206 is perpendicular to the surface of the conveyor belt 102. Meanwhile, the blocking turntable 405 drives the auxiliary gear 407 to mesh and rotate. The auxiliary gear 407 drives the other gear 404 to rotate through the rotating belt 401 connected to it. This causes the other gear 404 to drive the rotating rod 205 connected to it to rotate in the opposite direction until the other arc-shaped wall guide block 201, with the straight edge block 206, is perpendicular to the conveyor belt 102. During this process, some particles stuck on the arc-shaped wall guide block 201 are thrown onto the conveyor belt 102 due to the direction guided by the arc edge, thus better assisting in the collection of the bounced particles and reducing production costs. Example 4

[0039] like Figures 1-7As shown, based on the above embodiments 1 or 3, the guide assembly 2 further includes a bidirectional toothed disc 203. Two concave arc-shaped edges 204 are fixedly connected to the outer side of the bidirectional toothed disc 203. A toothed disc 202 is meshed with the outer side of the bidirectional toothed disc 203. The concave arc-shaped edges 204 and the arc-shaped edges of the toothed disc 202 are fitted together. The toothed disc 202 is fixedly installed at one end of the rotating rod 205. The bidirectional toothed disc 203 and the toothed disc 202 are separated. The rotating rod 205 is rotatably connected to the second holding block 105. Two connecting rods 104 are fixedly connected to one side of the long support plate 101. The top of the connecting rod 104 is fixedly connected to the mounting block 403. The rotating rod 205 is rotatably connected to the inside of the mounting block 403. As the gear tooth turntable 202 continues to rotate along the concave arc edge 204, the gear tooth edge of the bidirectional gear tooth turntable 203 meshes with the gear tooth edge of the gear tooth turntable 202, causing the bidirectional gear tooth turntable 203 to start rotating.

[0040] The pressure assembly 3 includes an auxiliary rod 304, which is rotatably connected between the second clamping block 105 and the first clamping block 103. A blocking block 303 is fixedly connected to the outer side of the auxiliary rod 304. A receiving block 302 is fixedly connected to one side of the blocking block 303. An airbag block 305 is fixedly connected to one side of the receiving block 302. A guide rod 307 is fixedly connected to the top of the airbag block 305. A pressure plate 301 is fixedly connected to the top of the guide rod 307. A bidirectional clamping block 306 is fixedly connected to the inner wall of the receiving block 302. The guide rod 307 is slidably connected to the inner side of the bidirectional clamping block 306. The blocking block 303 follows the auxiliary rod 304. Rotating, the pressure plate 301 faces the conveyor belt 102. Under the extension and limitation of the airbag block 305, the pressure plate 301 moves along the conveyor belt 102 towards the guide rod 307 by gravity under the clamping of the bidirectional clamping block 306 until it touches the sponge material. The pressure plate 301 squeezes the sponge material by its own gravity, and at the same time, it cooperates with the straight edge block 206 perpendicular to the conveyor belt 102 to squeeze the sponge material into a cuboid. The sponge material and the adhesive adhere to each other, so as to better cooperate in the next step of plasticization and enter the cuboid mold. This reduces the sponge material being discharged from the mold due to the large difference in volume between the sponge material and the mold, which is convenient for the production of composite sponge.
