Abstract
Description
Technical Field
[0001] This utility model relates to the field of sponge production technology, and in particular to a raw material storage device for sponge production. Background Technology
[0002] The main raw materials used in sponge production include polyols (such as polyether polyols), isocyanates (such as toluene diisocyanate TDI or diphenylmethane diisocyanate MDI), catalysts (amine catalysts and tin catalysts), foaming agents (physical foaming agents such as dichloromethane, chemical foaming agents such as azodicarbonamide), and surfactants (such as silicone oils). During the production process, the raw materials for sponge are stored in storage equipment.
[0003] In daily work, it has been found that existing raw material storage equipment for sponge production is prone to clumping during storage, especially for some solid polyols and solid foaming agents. This not only reduces the overall looseness of the raw materials but also seriously interferes with the subsequent feeding process, making it difficult to proceed smoothly and affecting production efficiency and product quality. Utility Model Content
[0004] The purpose of this invention is to solve, to at least partly, the shortcomings of existing technologies where raw materials are prone to clumping and affect material feeding, and to propose a raw material storage device for sponge production.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a raw material storage device for sponge production, comprising a tank, an inlet on the surface of the tank, an outlet at the bottom of the tank, a dispersing device on the surface of the tank, the dispersing device including a stirring shaft rotatably connected to the inner wall of the tank, a fixing frame fixedly connected to the surface of the tank, a motor fixedly connected to the surface of the fixing frame, the output end of the motor being driven by the stirring shaft via a belt, multiple stirring rods fixedly connected to the surface of the stirring shaft, multiple crushing rods rotatably connected to the inner walls of the multiple stirring rods, a transmission part being provided between the multiple crushing rods and the inner wall of the tank, and a pushing assembly being provided on the surface of the stirring shaft. Through these components, when the motor is turned on, the motor drives the stirring shaft to rotate via the belt, the stirring shaft drives the stirring rods to rotate, and the transmission part can control the rotation of the crushing rods. The stirring rods, in conjunction with the crushing rods, can evenly disperse the raw materials, ensuring the looseness of the raw materials.
[0006] Preferably, the transmission unit includes a gear ring fixed in the inner wall of the tank, and a gear is fixedly connected to one end of the crushing rod. The gear meshes with the gear ring. Through the above components, when the stirring rod drives the crushing rod to rotate, the gear and the gear ring can drive the crushing rod to rotate, thereby improving the crushing effect.
[0007] Preferably, both the inner and outer rings of the gear ring are provided with tooth grooves.
[0008] Preferably, an auxiliary plate is fixedly connected to the inner wall of the tank. The auxiliary plate allows the stirring shaft and the crushing rod to pass through. Through the above-mentioned components, the auxiliary plate can act as a barrier to the raw materials during stirring and dispersing.
[0009] Preferably, scrapers are fixedly connected to the surfaces of the plurality of stirring rods, and there are two scrapers. Through the above-mentioned components, when the stirring rods rotate, the scrapers can scrape the material on the inner wall of the tank, reducing the phenomenon of raw materials sticking to the inner wall of the tank.
[0010] Preferably, the feeding assembly includes a push rod that is slidably connected to the inner wall of the stirring shaft. A cylinder is fixedly connected to the surface of the stirring shaft. The output end of the cylinder is fixedly connected to one end of the push rod. The push rod is located directly above the discharge port. By opening the cylinder through the above components, the cylinder can drive the push rod to move out of the stirring shaft and push the push rod into the discharge port, realizing back-and-forth movement to facilitate unblocking and feeding.
[0011] Preferably, the lower end of the push rod is tapered, and the tapered head of the push rod facilitates better insertion into the raw material.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0013] 1. In this utility model, by setting up a dispersing device, the stirring rod rotates under the drive of the motor, providing basic power and stirring action for dispersing. The crushing rod not only revolves with the stirring rod, but also rotates on its own axis through the transmission part. This composite motion mode makes the dispersing effect more thorough, breaking up lumps from multiple angles and levels, reducing the phenomenon of raw material lumps caused by static accumulation, ensuring the looseness of the raw materials, which is conducive to subsequent accurate feeding and uniform mixing operations, and improving the overall practicality.
[0014] 2. In this utility model, by setting up a pushing component, when the raw material is blocked near the discharge port, the cylinder drives the push rod to extend out of the stirring shaft and insert into the discharge port. By moving back and forth, the raw material blocking the discharge port is pushed away, effectively clearing the discharge port and ensuring that the feeding process can proceed smoothly.

[0023] Specifically, the dispersing device 4 includes a stirring shaft 41 rotatably connected to the inner wall of the tank 1, a fixed frame 42 fixedly connected to the surface of the tank 1, a motor 43 fixedly connected to the surface of the fixed frame 42, the output end of the motor 43 being driven by the stirring shaft 41 via a belt, a plurality of stirring rods 45 fixedly connected to the surface of the stirring shaft 41, a plurality of crushing rods 46 rotatably connected to the inner wall of the plurality of stirring rods 45, a transmission part 49 being provided between the plurality of crushing rods 46 and the inner wall of the tank 1, and a pushing assembly 44 being provided on the surface of the stirring shaft 41.
[0024] In this embodiment: when the motor 43 is turned on, the motor 43 drives the stirring shaft 41 to rotate via the belt. The stirring shaft 41 drives the stirring rod 45 to rotate. The transmission unit 49 can control the rotation of the crushing rod 46. The stirring rod 45 and the crushing rod 46 can evenly disperse the raw materials to ensure the looseness of the raw materials.
[0025] Specifically, the transmission unit 49 includes a gear ring 492 fixed in the inner wall of the tank 1, and a gear 491 is fixedly connected to one end of the breaking rod 46. The gear 491 meshes with the gear ring 492.
[0026] In this embodiment: when the stirring rod 45 drives the crushing rod 46 to rotate, the gear 491 and the gear ring 492 can drive the crushing rod 46 to rotate, thereby improving the crushing effect.
[0027] Specifically, both the inner and outer rings of the gear ring 492 are provided with tooth grooves.
[0028] Specifically, an auxiliary plate 48 is fixedly connected to the inner wall of the tank 1, through which the stirring shaft 41 and the crushing rod 46 pass.
[0029] In this embodiment, the auxiliary plate 48 can act as a barrier to the raw materials during the mixing and dispersing process.
[0030] Specifically, scrapers 47 are fixedly connected to the surfaces of multiple stirring rods 45. There are two scrapers 47. When the stirring rods 45 rotate, the scrapers 47 can scrape the material from the inner wall of the tank 1, reducing the adhesion between the raw material and the inner wall of the tank 1.
[0031] Specifically, the feeding assembly 44 includes a push rod 442 that is slidably connected to the inner wall of the stirring shaft 41. A cylinder 441 is fixedly connected to the surface of the stirring shaft 41. The output end of the cylinder 441 is fixedly connected to one end of the push rod 442.

[0033] Specifically, the lower end of the push rod 442 is tapered, and the tapered head of the push rod 442 makes it easier to insert into the raw material.
[0034] Working principle: When mixing and dispersing the raw materials, the motor 43 is turned on. The motor 43 drives the mixing shaft 41 to rotate via the belt. The mixing shaft 41 drives the mixing rod 45 and multiple crushing rods 46 to rotate. As the crushing rods 46 rotate with the mixing rod 45, the gear 491 on the crushing rod 46, in conjunction with the gear ring 492, can drive the crushing rod 46 itself to rotate, improving the overall mixing and dispersing effect of the raw materials and ensuring the looseness of the raw materials. During the mixing and dispersing process, the mixing rod 45 can drive the scraper 47 to scrape the material on the inner wall of the tank 1, and the auxiliary plate 48 can act as a barrier for the raw materials. When discharging through the discharge port 3, the cylinder 441 is turned on. The cylinder 441 can drive the push rod 442 to be inserted into the discharge port 3 and move back and forth to ensure smooth discharge.
