Description

Technical Field

[0001] This application relates to the field of sponge production, and in particular to a sponge foaming device. Background Technology

[0002] A sponge is a porous material with good water absorption, which can be used to clean items. It is usually formed by mixing foaming resin, foaming aids, and adhesive resin together and then foaming them.

[0003] In existing production line equipment for continuous sponge production, the mixed raw materials are usually fed onto a conveyor belt for foaming, and then conveyed sequentially through a baking device and a cotton collecting device to achieve continuous sponge production.

[0004] The degree of mixing of various raw materials during the foaming process affects the quality of the sponge. However, existing sponge foaming devices do not mix the raw materials sufficiently and the material is not fed evenly, which easily leads to insufficient mixing and affects the quality of the sponge. Summary of the Invention

[0005] To improve the quality of sponges, this application provides a sponge foaming device.

[0006] The sponge foaming device provided in this application adopts the following technical solution: A sponge foaming device includes an inlet pipe, a main pipe, a sliding rod, a stirring plate, and an outlet pipe. The inlet pipe is connected to the main pipe, and the main pipe is connected to the outlet pipe. The main pipe has a receiving cavity, and the stirring plate is disposed in the receiving cavity. The stirring plate is fixedly connected to the sliding rod, and the sliding rod is slidably connected to the main pipe. The sliding direction of the sliding rod is parallel to the length direction of the main pipe.

[0007] By adopting the above technical solution, the mixed raw materials are stirred with a stirring plate before being discharged, thereby improving the mixing degree of the raw materials and improving the quality of the sponge.

[0008] Preferably, it further includes a forming table, a fixing frame, and a fixing seat. The fixing frame is fixedly connected to the upper end of the forming table. The fixing frame is provided with a sliding groove. The fixing seat is slidably embedded in the sliding groove. The sliding direction of the fixing seat is parallel to the extension direction of the fixing frame. The main pipe is fixedly connected to the fixing seat.

[0009] By adopting the above technical solution, the liquid outlet pipe slides continuously during the liquid outlet process, which stirs the mixed liquid on the molding table, further improving the mixing degree of raw materials and improving the quality of sponge.

[0010] Preferably, it further includes a drive motor and a conveyor belt, the conveyor belt being fixedly connected to the fixed base, the conveyor belt being parallel to the extension direction of the fixed frame, the motor housing of the drive motor being fixedly connected to the fixed frame, and the motor shaft of the drive motor being connected to the conveyor belt.

[0011] By adopting the above technical solution, the drive motor drives the conveyor belt to drive the fixed seat to slide, so that the fixed seat can move back and forth on the platform. The operation is simple, the sliding is stable, and it is easy to control.

[0012] Preferably, the fixing frame is evenly divided into four segments along its circumference, including a first connecting rod, a second connecting rod, a third connecting rod, and a fourth connecting rod. The first connecting rod, the second connecting rod, the third connecting rod, and the fourth connecting rod are connected end to end in sequence. The first connecting rod and the third connecting rod are located at both ends of the fixing frame. The second connecting rod is parallel to the fourth connecting rod. When the fixing seat slides to the first connecting rod and the third connecting rod, the sliding rod slides downward. When the fixing seat slides to the second connecting rod and the fourth connecting rod, the sliding rod slides upward.

[0013] By adopting the above technical solution, the liquid outlet pipe continuously discharges liquid during the sliding process of the fixed seat. The fixed seat slides circumferentially along the fixed frame, resulting in more raw material in the middle of the molding platform than on both sides. When the sliding rod slides to both sides of the fixed frame, the sliding rod slides downward to accelerate the liquid discharge. When the sliding rod slides to the middle section of the fixed frame, the sliding rod slides upward to slow down the liquid discharge, reducing the degree to which the raw material in the middle of the molding platform is greater than on both sides. This makes the sponge molding more uniform and flat, improving the quality of the sponge.

[0014] Preferably, the device further includes a bracket, a rack, and a rotating disk. The bracket is connected to a fixed frame. The bracket includes a first support rod, a second support rod, and a third support rod. The first and third support rods are respectively disposed on the outer periphery of the first and third connecting rods. The side of the first support rod facing the first connecting rod is connected to the rack, and the side of the third support rod facing the third connecting rod is connected to the rack. The second support rod is disposed between the second and fourth connecting rods. The length direction of the second support rod is parallel to the length direction of the second connecting rod. Both sides of the second support rod are connected to the rack. The sliding rod is a lead screw. The rotating disk is coaxially rotatably connected to the sliding rod, and the outer periphery of the rotating disk meshes with the rack.

[0015] By adopting the above technical solution, when the fixed seat slides to the first connecting rod, the rotating disk engages with the rack on the first support rod, and the sliding rod moves downward; when the fixed seat slides to the second connecting rod, the rotating disk engages with the rack on the second support rod, the rotating disk reverses its rotation, and the sliding rod moves upward; when the fixed seat slides to the third connecting rod, the rotating disk engages with the rack on the third support rod, the rotating disk reverses its rotation, and the sliding rod moves downward; when the fixed seat slides to the fourth connecting rod, the rotating disk engages with the rack on the second support rod, the rotating disk reverses its rotation, and the sliding rod moves upward; the fixed seat drives the rotating disk to rotate during the sliding process, thereby driving the sliding rod to move up and down, which is convenient to operate, requires no additional drive source to drive the sliding rod to move up and down, and saves resources.

[0016] Preferably, the length of the second support rod is equal to the length of the second connecting rod.

[0017] By adopting the above technical solution, the forward and reverse rotation distances of the rotating disk are equal, so that the rotating disk moves up and down continuously within a certain range of the sliding rod, maintaining the continuous and stable operation of the rotating disk.

[0018] Preferably, the bracket is provided with a limiting groove, the rack is fixedly connected to the bottom of the limiting groove, and the rotating disk is embedded in the limiting groove and meshes with the rack.

[0019] By adopting the above technical solution, the rotating disk is not easily moved up and down by the sliding rod during rotation, and then disengages from the rack. The limiting groove makes the meshing between the rotating disk and the rack stable.

[0020] Preferably, the mixing plate is provided with multiple through holes.

[0021] By adopting the above technical solution, the multiple holes of the mixing plate allow the raw materials to be dispersed before being discharged, and further mixed, thereby increasing the degree of mixing of the raw materials, making the mixing more uniform, and improving the quality of the sponge.

[0022] Preferably, the outer periphery of the stirring plate fits against the inner wall of the receiving cavity.

[0023] By adopting the above technical solution, the mixing plate further stirs the raw liquid in the main pipe, improves the mixing degree of the raw materials, and improves the quality of the sponge.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. Before dispensing the mixed raw materials, stir them with a stirring plate to improve the mixing degree and enhance the quality of the sponge; 2. The liquid outlet tube slides continuously during the liquid outlet process, which agitates the mixed liquid on the molding table, further improving the mixing degree of raw materials and improving the quality of the sponge; 3. Liquid is continuously discharged from the outlet pipe during the sliding process of the fixed seat. The fixed seat slides around the fixed frame, resulting in more raw material in the middle of the molding table than on the sides. When the sliding rod slides to the sides of the fixed frame, it slides downward to accelerate the discharge. When the sliding rod slides to the middle of the fixed frame, it slides upward to slow down the discharge. This reduces the degree to which the raw material in the middle of the molding table is greater than on the sides, making the sponge molding more uniform and flat, and improving the quality of the sponge.
