Description

Technical Field

[0001] This utility model relates to the field of latex sponge processing technology, specifically to a dry latex sponge processing device. Background Technology

[0002] In the industrial production of dry latex foam, one of the core steps is to thoroughly and uniformly mix the latex matrix with various raw materials such as fillers and additives. The mixing effect directly determines the physical properties (such as elasticity, hardness, and abrasion resistance) and performance stability of the finished foam. Among these materials, illite powder, due to its excellent adsorption, dispersibility, and cost advantages, has become a widely used core filler in the industry. Its uniform dispersion in the latex matrix is ​​a key factor in ensuring the consistency of performance across batches of finished foam products.

[0003] Currently, most dry latex sponge processing mixing devices use a single-point feeding method, where all raw materials (including the latex matrix, illite powder, additives, etc.) are fed into the mixing tank through a single feed pipe fixed to the top or side wall. This feeding method has significant technical drawbacks: Firstly, the raw materials fed at a single point are prone to localized accumulation in specific areas within the mixing tank, especially powdered fillers like illite powder. After accumulation, the high local concentration can easily lead to agglomeration. Even with prolonged high-speed stirring by the stirring mechanism, it is difficult to completely break up the agglomerates and achieve uniform dispersion with the latex matrix, ultimately resulting in localized performance differences in the finished sponge (such as some areas having higher hardness and some areas having insufficient elasticity). Secondly, to improve the problems of localized accumulation and agglomeration, the stirring time needs to be significantly extended. This not only increases the power consumption of the equipment but also reduces the overall production efficiency, failing to meet the low-cost, high-efficiency requirements of continuous industrial production. Utility Model Content

[0004] In view of the above situation, this utility model provides a dry latex sponge processing device to solve the problems of uneven mixing and high energy consumption caused by single-point feeding.

[0005] The technical solution of this utility model is as follows: a dry latex sponge processing device, including a mixing tank and a storage tank. The top of the mixing tank is connected to an annular plate, and a material passage groove is opened inside the annular plate. Multiple baffles are connected inside the material passage groove. The top of the mixing tank is provided with a discharge groove that is offset from the baffles. The bottom of the storage tank is connected to a discharge pipe, and a fan-shaped plate is connected to the outer surface of the discharge pipe. The fan-shaped plate is rotatably connected inside the material passage groove.

[0006] The mixing tank has a support leg connected to its outer surface near the bottom, and a discharge pipe is connected to the bottom of the mixing tank.

[0007] The mixing tank is equipped with a rotating stirring shaft inside, and multiple stirring blades are connected to the outer surface of the stirring shaft.

[0008] The upper surface of the mixing tank is connected to a mounting bracket, on which a motor is mounted. One of the output ends of the motor is connected to the top of the mixing shaft.

[0009] The other output end of the motor is connected to a drive shaft, the outer surface of the drive shaft is connected to a sleeve, the outer surface of the sleeve is connected to a connecting plate, and the other side of the connecting plate is connected to a storage tank.

[0010] The storage tank has a first support plate and a second support plate connected to its outer surface near the bottom. The annular plate has a first annular groove and a second annular groove inside. The side of the first support plate away from the storage tank is rotatably connected to the inside of the first annular groove, and the side of the second support plate away from the storage tank is rotatably connected to the inside of the second annular groove.

[0011] In operation, this invention utilizes an annular plate, a material chute, and equidistantly distributed baffles, along with a rotatable storage tank and a fan-shaped plate, to achieve intermittent multi-point feeding. During the rotation of the storage tank, raw materials are fed into the mixing tank at multiple points through the gaps between adjacent baffles, completely avoiding the local accumulation problem of traditional single-point feeding. Especially for fillers that are prone to agglomeration, such as illite powder, the raw materials are dispersed by the synchronously rotating mixing blades upon feeding, effectively suppressing agglomeration and significantly improving processing effect and efficiency.

[0012] The cooperation between the first support plate, the first annular groove, the second support plate, and the second annular groove can effectively prevent horizontal deviation or shaking when the storage tank rotates, ensuring that the feed pipe and the fan-shaped plate always move stably within the feed trough, thus guaranteeing the continuity and stability of the feeding and mixing process.

[0014] like Figure 1-4 As shown, this utility model provides a dry latex sponge processing device, including a mixing tank 1 and a storage tank 11. An annular plate 14 is connected to the top of the mixing tank 1. A material passage 15 is formed inside the annular plate 14. Multiple equally spaced baffles 16 are connected inside the material passage 15. A discharge trough offset from the baffles 16 is formed at the top of the mixing tank 1. A discharge pipe 12 is connected to the bottom of the storage tank 11. A fan-shaped plate 13 is connected to the outer surface of the discharge pipe 12 and is rotatably connected inside the material passage trough 15. Multiple baffles 16 are welded and fixed at equal intervals along the length of the feed trough 15. The gap between adjacent baffles 16 is used for the passage of raw materials. The feed trough at the top of the mixing tank 1 is staggered from the baffles 16 to prevent the baffles 16 from blocking the feed trough and preventing the raw materials from falling in. The fan-shaped plate 13 is made of a metal plate that matches the width and depth of the feed trough 15. When it is rotatably connected in the feed trough 15, it can rotate synchronously with the feed pipe 12 and can also fit tightly with the upper surface of the baffle 16 in the initial state to form a seal to prevent the raw materials in the storage tank 11 from leaking.

[0015] To ensure the stable placement of the mixing tank 1 and the discharge of the mixed material, a support leg 2 is connected to the outer surface of the mixing tank 1 near the bottom. A discharge pipe 3 is connected to the bottom of the mixing tank 1. The support leg 2 is made of solid metal rod, and a rubber anti-slip pad can be glued to the lower end to enhance the stability of the mixing tank 1 when placed on the ground or workbench and to prevent displacement due to vibration during operation. The discharge pipe 3 is welded to the center of the bottom of the mixing tank 1 to ensure that the material in the tank can be completely discharged. The discharge pipe 3 can be equipped with a control valve as needed, and the operator can control the timing of discharge by opening and closing the valve.

[0016] To achieve mixing of raw materials in the tank, a stirring shaft 6 is rotatably installed inside the stirring tank 1. Multiple stirring blades 7 are connected to the outer surface of the stirring shaft 6. The multiple stirring blades 7 are made of metal plates and are evenly distributed along the length of the stirring shaft 6 to ensure that the materials in the upper and lower layers of the tank can be fully mixed and to avoid uneven mixing in certain areas.

[0017] A mounting bracket 4 is connected to the upper surface of the mixing tank 1. A motor 5 is mounted on the mounting bracket 4. One of the output ends of the motor 5 is connected to the top of the stirring shaft 6. When the motor 5 is started, it can drive the stirring shaft 6 and the stirring blades 7 to rotate, thereby stirring and mixing the raw materials inside the mixing tank 1.

[0018] Another output end of the motor 5 is connected to a drive shaft 8. A sleeve 9 is connected to the outer surface of the drive shaft 8. A connecting plate 10 is connected to the outer surface of the sleeve 9. The other side of the connecting plate 10 is connected to the storage tank 11. By setting the drive shaft 8, sleeve 9 and connecting plate 10, the storage tank 11 can be driven to rotate at a constant speed along the feed chute 15 while the raw materials are being stirred.

[0019] A first support plate 19 and a second support plate 20 are connected to the outer surface of the storage tank 11 near the bottom. The annular plate 14 has a first annular groove 17 and a second annular groove 18 inside. The side of the first support plate 19 away from the storage tank 11 is rotatably connected to the inside of the first annular groove 17, and the side of the second support plate 20 away from the storage tank 11 is rotatably connected to the inside of the second annular groove 18. Through the cooperation between the first support plate 19, the first annular groove 17, the second support plate 20 and the second annular groove 18, horizontal deviation or shaking of the storage tank 11 can be effectively avoided when it rotates, ensuring that the feed pipe 12 and the fan-shaped plate 13 always move stably within the feed trough 15, and ensuring the continuity and stability of the feeding and mixing process.

[0020] In operation, the bottom surface of the fan-shaped plate 13 and the upper surface of the baffle 16 are tightly fitted together in the initial state, forming a seal on the bottom of the storage tank 11. The operator can load the pre-weighed illite powder, additives and other fillers into the storage tank 11. At the same time, the latex matrix and water are slowly added into the mixing tank 1 through the area of ​​the feed trough 15 that is not covered by the fan-shaped plate 13 until the preset feeding amount is reached. Then start motor 5. One output end of motor 5 drives the stirring shaft 6 to rotate. The stirring blades 7 on the outer surface of the stirring shaft 6 rotate synchronously with the stirring shaft 6 in the mixing tank 1, forming a continuous stirring flow field to prepare for subsequent raw material mixing. The other output end of the motor 5 drives the transmission shaft 8 to rotate. The transmission shaft 8 drives the storage tank 11 to rotate around the axis of the transmission shaft 8 through the sleeve 9 and the connecting plate 10. The rotation of the storage tank 11 drives the feeding pipe 12 and the sector plate 13 to rotate in the feed trough 15. When the sector plate 13 rotates to the gap between two adjacent baffles 16, the sector plate 13 separates from the baffles 16. Under the action of gravity, the raw material in the storage tank 11 enters the mixing tank 1 through the feeding pipe 12, the gap of the feed trough 15, and the feeding trough at the top of the mixing tank 1 in sequence. The newly entered raw material is immediately dispersed by the rotating stirring blades 7 and fully mixed with the latex matrix to avoid local accumulation. As the storage tank 11 continues to rotate, the sector plate 13 completes one intermittent feeding every time it passes through the gap of a baffle 16, realizing the multi-point and uniform input of raw materials. The motor 5 runs continuously for a preset time. After all the raw materials are put into the mixing tank 1 and fully mixed by the mixing blades 7, the motor 5 is turned off and the control valve on the discharge pipe 3 at the bottom of the mixing tank 1 is opened. The evenly mixed material is discharged through the discharge pipe 3 and enters the subsequent dry latex sponge molding and other processes.
