Description

Technical Field

[0001] The invention belongs to the technical field of chemical machinery and equipment, in particular to a polyurethane foaming continuous feeding device. Background Art

[0002] As a high-performance material, polyurethane foam is widely used in many fields such as construction, transportation, cold chain, and home furnishing. Its production process has extremely high requirements on the raw material ratio, mixing efficiency, and stability of the feeding system. The polyurethane foam continuous feeding device is a special equipment designed to meet this demand.

[0003] However, the traditional feeding device usually adopts a single two-stage stirring method, that is, the stirrer rotates and stirs at a fixed position. This stirring method has many shortcomings: first, the stirring range is limited. Since the stirrer can only rotate at a fixed position, it can only cover a part of the area in the mixing barrel, resulting in uneven mixing of materials, which not only affects the mixing quality of the materials, but also may affect the performance and use effect of the final product. Secondly, the stirring efficiency is low. Due to the limited stirring range, the traditional device takes a longer time to complete the mixing of materials, which not only increases the production cost, but also may lead to low production efficiency. At the same time, uneven stirring may also lead to The materials will agglomerate or stratify during the mixing process, which will further affect the mixing quality. Furthermore, the stirring force is unevenly distributed. When the agitator of the traditional device rotates at a fixed position, the stirring force is often concentrated in a specific area, resulting in uneven distribution of stirring force on the materials during the mixing process. This will affect the mixing effect and uniformity of the materials, thereby affecting the quality and performance of the product. Finally, it cannot meet the needs of continuous feeding. Due to the single stirring method and low stirring efficiency, the traditional device often cannot meet the continuous feeding needs on the production line, which limits the application of the device on the production line and reduces production efficiency. Therefore, it needs to be improved and optimized. Summary of the invention

Motor 2 drives the auger to rotate in the feeding pipe to achieve continuous transportation of raw materials. This design ensures the stability and continuity of the feeding process, avoids production stagnation caused by raw material interruption, protects the motor and extends its service life: the design of the motor protection shell provides effective protection for Motor 2, prevents the erosion of the motor by impurities such as dust and moisture, which not only extends the service life of the motor, but also improves the reliability of the entire feeding system. Compared with traditional devices, the device enhances the adaptability under different production needs. By adjusting the number and capacity of the storage barrels, as well as the parameters of Motor 2 and the auger, it can flexibly adapt to the needs of different scales and production conditions.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figures 1 to 9As shown, the present invention provides a polyurethane foam continuous feeding device, including a base 1, a glass protection frame 2 and a support frame 3 are fixedly installed on the top of the base 1, the support frame 3 is inside the glass protection frame 2, a mixing barrel 4 is fixedly installed on the inner wall of the support frame 3, a top cover 5 is fixedly installed on the top of the mixing barrel 4, a motor 6 is arranged on the top of the top cover 5, a rotating rod 7 is fixedly installed on the output shaft of the motor 6, the bottom end of the rotating rod 7 extends into the mixing barrel 4 and is rotatably connected to the top cover 5, a thin gear 8 is fixedly sleeved on the outer wall of the rotating rod 7, a mounting block 9 is fixedly installed on the top of the motor 6, a tooth groove 10 is provided on the outer wall of the mounting block 9, a fixing plate 11 is fixedly installed on the top of the top cover 5, and the mounting block 9 is slidably connected to the fixing plate 11.

[0030] The mixing barrel 4 is used as the core component of the device, and the top cover 5 fixedly installed on the top ensures the closedness and safety of the mixing process. Through the drive of the motor 6 and the meshing of gears and bevel gears at various levels, efficient stirring and uniform distribution of the materials are achieved. At the same time, the movement of the mounting block 9 in the vertical direction further enhances the mixing effect. Compared with the traditional device, the mixing effect is further enhanced by the movement of the mounting block 9 in the vertical direction. As the mounting block 9 moves up and down, the stirring blades 23 and the mixing chamber 24 are also stirred and mixed more comprehensively in the mixing barrel 4. This three-dimensional stirring method not only breaks the limitations of traditional two-dimensional stirring, but also enables the materials to be subjected to more uniform and sufficient stirring force during the mixing process, thereby achieving uniform distribution of the materials and enabling continuous feeding of polyurethane foaming materials.

[0031] like Figures 1 to 4 As shown, an annular frame 26 is provided on the top of the mixing barrel 4, and a plurality of storage barrels 27 are fixedly installed on the inner wall of the annular frame 26, and feeding pipes 28 are fixedly installed on the tops of the plurality of storage barrels 27, respectively. The bottoms of the feeding pipes 28 are fixedly connected to the top of the top cover 5, and the plurality of feeding pipes 28 are all connected to the interior of the mixing barrel 4, and a motor protection shell 291 is fixedly installed on the side of the plurality of feeding pipes 28 away from the mixing barrel 4, and a plurality of motors 29 are fixedly installed on the inner walls of the plurality of motor protection shells 291, and the output shafts of the plurality of motors 29 extend into the corresponding feeding pipes 28 and are rotatably connected to the corresponding feeding pipes 28, and augers 30 are fixedly installed on the output shafts of the plurality of motors 29, and the plurality of augers 30 are respectively located inside the corresponding feeding pipes 28.

[0032] Through the design of the annular frame 26 and the storage barrel 27, multiple raw materials can be stored and fed in an orderly manner at the same time, which not only improves the feeding efficiency, but also ensures the accurate ratio of the raw materials, thereby ensuring the quality of the polyurethane foam material. Since each storage barrel 27 is connected to the mixing barrel 4 through an independent feeding pipe 28, the amount of each raw material added can be accurately controlled. This accurate raw material ratio is crucial for the production of high-quality polyurethane foam materials. Motor 29 drives the auger 30 to rotate in the feeding pipe 28 to achieve continuous transportation of raw materials. This design ensures the stability and continuity of the feeding process, avoids production stagnation caused by raw material interruption, protects the motor and extends its service life: the design of the motor protection shell 291 provides effective protection for motor 2, preventing dust, moisture and other impurities from corroding the motor, which not only extends the service life of the motor, but also improves the reliability of the entire feeding system. Compared with traditional devices, the device enhances the adaptability under different production needs. By adjusting the number and capacity of the storage barrels 27, as well as the parameters of motor 29 and auger 30, it can flexibly adapt to the needs of different scales and production conditions.

[0033] like Figures 8 to 9 As shown, a limiting protrusion 13 is fixedly installed on one side of the mounting block 9 close to the fixing plate 11, and a limiting groove 12 is provided on one side of the fixing plate 11 close to the limiting protrusion 13. The limiting groove 12 is adapted to the limiting protrusion 13 and is slidably connected to the limiting protrusion 13.

[0034] The close fit between the limiting protrusion 13 and the limiting groove 12 ensures the stability of the connection between the mounting block 9 and the fixing plate 11. Even if the equipment is subjected to large vibration or impact force during operation, the connection can remain stable and is not easy to loosen or fall off. The sliding design of the limiting protrusion 13 in the limiting groove 12 enables the mounting block 9 to move within a certain range relative to the fixing plate 11.

[0035] like Figure 5 As shown, a fixing block 22 is fixedly installed on the top of the top cover 5, and a rotating rod 14 is rotatably installed on the side where the fixing block 22 and the fixing plate 11 are close to each other. A tooth column 15 and a bevel gear 16 are fixedly sleeved on the outer wall of the rotating rod 14.

[0036] By means of the tooth column 15 fixedly sleeved on the outer wall of the rotating rod 2 14, the tooth groove 10 can realize precise meshing transmission. At the same time, the meshing of the bevel gear 16 and the bevel gear 2 18 provides an efficient transmission path for the entire feeding device. This design not only improves the transmission efficiency, but also ensures the stability and reliability of the transmission. The stable installation of the fixed block 22 and the fixed plate 11, and the rotational installation of the rotating rod 2 14 between the two, make the entire transmission mechanism compact and stable. This design greatly saves space and improves the overall strength and rigidity of the equipment.

[0037] like Figure 5 As shown, a tooth groove 10 is provided on one side of the mounting block 9 close to the tooth column 15 , and the tooth groove 10 is meshed with the tooth column 15 .

[0038] Through the meshing design of the tooth groove 10 and the tooth column 15, the mounting block 9 can accurately reciprocate in the vertical direction as the tooth column 1 rotates, thereby driving the motor 6, the rotating rod 7 and the stirring blade 23 to move together. As the mounting block, the motor 6, the rotating rod 7 and the stirring blade 23 move vertically together, the stirring blade 23 can cover a wider mixing area, which not only increases the contact area between the stirring blade and the material, but also promotes the up and down flipping of the material in the mixing barrel, thereby significantly improving the mixing effect.

[0039] like Figure 5 As shown, a rotating rod 3 17 is rotatably mounted on the top of the top cover 5 , and a bevel gear 2 18 and a gear column 2 19 are fixedly sleeved on the outer wall of the rotating rod 3 17 , and the bevel gear 2 18 is meshed with the bevel gear 1 16 .

[0040] Through the meshing design of bevel gear 2 18 and bevel gear 1 16, the rotating rod 3 17 can effectively transmit power to other components through the transmission of bevel gear 2 18, and realize the steering function at the same time, which not only improves the transmission efficiency, but also ensures the stability and reliability of the transmission, and provides a strong guarantee for the continuous operation of the polyurethane foaming continuous feeding device.

[0041] like Figures 1 to 9 As shown, a T-shaped column 20 is rotatably mounted on the top of the top cover 5, and a gear column 3 21 is fixedly sleeved on the outer wall of the T-shaped column 20, and the gear column 3 21 is meshed with the thin gear 8 and the gear column 2 19 respectively.

[0042] Through the meshing design of gear column three 21, thin gear 8 and gear column two 19, an efficient transmission mechanism is formed. When the thin gear 8 rotates, the thin gear 8 drives gear column three 21 to rotate, and gear column three 21 drives gear column two 19 to rotate, so that power is transmitted. The design of T-column 20 and gear column three 21 makes the entire transmission mechanism compact and stable, and the connection between them is firm and reliable, and can withstand large torque and load. At the same time, this design also reduces energy loss and noise pollution in the transmission process, and improves the overall performance of the equipment.

[0043] like Figures 8 to 9 As shown, a discharge pipe 41 is fixedly installed on the top of the mixing barrel 4 , and the discharge pipe 41 extends out of the glass protection frame 2 and is fixedly connected to the glass protection frame 2 .

[0044] The design of the discharge pipe 41 ensures that the material in the mixing barrel 4 can flow out smoothly, avoiding blockage and accumulation of materials at the outlet, which not only improves production efficiency, but also ensures the continuity and stability of material flow. The discharge pipe 41 extends out of the glass protection frame 2 and is fixedly connected to the glass protection frame. Such a design effectively isolates the operating area from potential sources of danger. The glass protection frame provides a transparent observation window, allowing operators to observe and operate without contacting the material, thereby ensuring the safety of the operation process.

[0045] like Figure 5 to Figure 6 As shown, two stirring blades 23 and two mixing chambers 24 are fixedly sleeved on the bottom outer wall of the rotating rod 7, and the two stirring blades 23 are respectively located inside the corresponding mixing chambers 24.

[0046] The design of the stirring blade 23 being located inside the mixing chamber 24 ensures that the material is fully stirred and mixed in the mixing chamber. The rotation of the stirring blade can drive the material to perform violent turbulent motion, thereby effectively promoting the uniform distribution between different components and improving the mixing efficiency. Each mixing chamber 24 is provided with a stirring blade 23, so that the material can be evenly distributed in all corners of the mixing chamber during the mixing process, avoiding excessive accumulation or loss of material in a certain area, and further improving the mixing quality.

[0047] like Figure 6 As shown, a plurality of arc-shaped grooves 25 are respectively formed on the outer walls of the two mixing chambers 24, and the arc-shaped grooves 25 are designed to be distributed at equal distances.

[0048] The design of the arc groove 25 not only increases the outer wall surface area of ​​the mixing chamber, but also promotes the turbulence and shearing effect of the material during the mixing process, so that the material can be mixed more fully and evenly, thereby improving the quality of the polyurethane foam material.

[0049] The working principle and use process of the present invention:

[0050] A variety of raw materials are stored in a storage barrel 27 on the annular frame 26. When feeding is needed, the motor 29 is started to drive the auger 30 to rotate in the corresponding feed pipe 28. The auger 30 continuously transports the raw materials in the storage barrel 27 to the mixing barrel 4. The motor 16 is started, and the output shaft of the motor 16 drives the rotating rod 17 to rotate. The rotating rod 17 drives the stirring blade 23 and the mixing chamber 24 to rotate, and the materials in the mixing barrel 4 are fully mixed. At the same time, the rotating rod 17 drives the thin gear 8 to rotate, and the thin gear 8 and the tooth column 3 21 are rotated. The meshing drives the gear column three 21 to rotate, the gear column three 21 drives the gear column two 19 to rotate, the gear column two 19 drives the rotating rod three 17 and the bevel gear two 18 to rotate, the bevel gear two 18 meshes with the bevel gear one 16 to drive the bevel gear one 16 to rotate, the bevel gear one 16 drives the rotating rod two 14 and the gear column one 15 to rotate, the gear column one 15 meshes with the tooth groove 10, and drives the mounting block 9 to move up and down in the vertical direction, and the mounting block 9 drives the rotating rod one 7 and the stirring blade 23 and the mixing chamber 24 to move together, so as to realize a three-dimensional stirring method.
