Technical Field

[0001] This utility model relates to the field of automotive seat cushion production technology, and in particular to a foam storage tank for producing automotive seat cushions. Background Technology

[0002] In the production of car seat cushions, the uniformity of the mixing of foaming raw materials directly affects the foaming quality and physical properties of the cushions. Therefore, as a key piece of equipment for mixing and temporarily storing raw materials, the performance of the foaming storage tank is crucial to production efficiency and product quality.

[0003] Existing equipment typically employs a single stirring shaft with stirring blades, resulting in a limited stirring range. This can easily lead to uneven mixing of materials within the tank, affecting the consistency of the foaming raw material's reaction. Consequently, this can cause quality issues in the produced car seat cushions, such as uneven density and inconsistent hardness. Furthermore, it may result in raw material waste and reduced material utilization. Therefore, we provide a foaming storage tank for the production of car seat cushions. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Existing technologies often employ a single stirring structure, which reduces the mixing effect of materials. This embodiment provides a foaming storage tank for producing automotive seat cushions, which can fully mix materials, improve the uniformity of material mixing, and enhance the production quality of automotive seat cushions. Please refer to... Figure 1 - Figure 5 This foaming storage tank for producing automotive seat cushions includes a storage tank 1. Inside and at the bottom of the storage tank 1 are a mixing mechanism 2 for thoroughly mixing materials, and a shock-absorbing and protective mechanism 3 to reduce shaking during mixing. The mixing mechanism 2 expands the mixing range, improves the uniformity of material mixing, and increases material utilization. The shock-absorbing and protective mechanism 3 effectively reduces shaking during mixing, providing cushioning and protection, preventing equipment damage, extending service life, and ensuring the stability and safety of equipment operation.

[0019] Existing equipment typically employs a single mixing structure with a narrow mixing range, which can easily lead to uneven mixing of materials within the tank. This affects the consistency of the foaming raw material reaction, resulting in quality defects such as uneven density and hardness deviations in the produced car seat cushions. It can also cause raw material waste and reduce material utilization. To address these issues, the mixing mechanism 2 includes a mounting groove 21 located inside and above the storage tank 1. A mixing motor 22 is mounted at the top of the storage tank 1. A triangular mounting bracket 23 is fixedly mounted at the bottom of the mounting groove 21. A mixing shaft 24, passing through the triangular mounting bracket 23 and through the mounting groove 21, is mounted on the output shaft of the mixing motor 22. Both the mixing shaft 24 and the mounting rod 210 are coated with an anti-stick coating to reduce the adhesion of foaming raw materials to the shaft and rod surfaces during mixing, minimizing waste caused by material residue. This also facilitates subsequent cleaning and maintenance, ensuring smooth equipment operation. Multiple mixing components 25 are mounted on the mixing shaft 24, and two scraper rods 26 are mounted at the bottom of the mixing shaft 24. The output shaft of the mixing motor 22 is equipped with... The drive gear 27 and the three corners of the triangular mounting bracket 23 are rotatably connected to a rotating shaft 28. A linkage gear 29 that meshes with the drive gear 27 is installed above the rotating shaft 28. A mounting rod 210 that passes through the mounting groove 21 is installed at the bottom of the rotating shaft 28. The stirring rods 211 on the three sets of mounting rods 210 are staggered to expand the stirring coverage area, avoid stirring blind spots, and ensure that materials in different positions are fully stirred. Together with the stirring component 25 on the stirring shaft 24, a multi-dimensional and dead-angle-free stirring effect is formed, which further improves the uniformity of material mixing, ensures consistent reaction of foaming raw materials, and thus ensures the production quality of car seat cushions. Multiple sets of stirring rods 211 are installed on the outer wall of the three sets of mounting rods 210. Material enters storage tank 1 through the feed inlet and is powered by stirring motor 22. Its output shaft drives stirring shaft 24 and drive gear 27 to rotate. Stirring shaft 24 passes through mounting groove 21 and connects to multiple sets of stirring components 25, which can directly stir the material in the middle of storage tank 1. At the same time, drive gear 27 meshes with linkage gear 29 at the top of rotating shaft 28 on triangular mounting bracket 23, driving three sets of rotating shafts 28 to rotate synchronously. This causes mounting rod 210 and multiple sets of stirring rods 211 at the bottom of rotating shaft 28 to rotate accordingly. Since the stirring rods 211 on the three sets of mounting rods 210 are staggered and work together with the stirring components 25 on stirring shaft 24, a multi-dimensional stirring range is formed, thereby achieving full and uniform mixing of materials and improving the production quality of materials.

[0020] Example 2 Based on Example 1, such as Figure 1 - Figure 5As shown, existing technologies often employ a single stirring structure, which reduces the stirring effect of materials. However, during the stirring process, due to the violent movement of materials, the equipment is prone to significant shaking and vibration. Existing storage tanks often lack effective buffering and shock absorption structures, resulting in the inability to effectively absorb vibration energy. This not only generates significant noise pollution, affecting the workshop working environment, but also causes loosening and increased wear of equipment connecting parts due to long-term high-frequency vibration, shortening the equipment's service life. Therefore, this device also incorporates a structure to reduce the shaking of the storage tank.

[0021] During the mixing process, the violent movement of materials will cause the equipment to shake and vibrate significantly, which will not only cause significant noise pollution and affect the working environment of the workshop, but also cause the connecting parts of the equipment to loosen and wear more due to long-term high-frequency vibration, thus shortening the service life of the equipment. In order to solve the above problems, The vibration damping and protection mechanism 3 includes a partition 31 connected to the bottom of the storage tank 1 and a base 32 placed on the ground. The bottom connecting end of the partition 31 is slidably connected to the inside of the fixed cylinder 33, which can guide the up and down movement of the partition 31, ensuring that it moves stably in a fixed direction during vibration buffering, avoiding displacement due to shaking and affecting the buffering effect, and enhancing the stability of the structural connection. Multiple sets of fixed cylinders 33 are installed on the top of the base 32. The fixed cylinders 33 are connected to the bottom connecting end of the partition 31 with buffer springs 34 inside. Multiple sets of dampers 35 are installed between the partition 31 and the base 32. The dampers 35 are symmetrically distributed in pairs between the partition 31 and the base 32, which can evenly distribute the vibration energy. Through the damping effect, the excessive shaking and rebound of the partition 31 and the storage tank 1 are effectively suppressed. In conjunction with the buffer springs 34, the vibration damping effect is further improved, reducing the impact of high-frequency vibration on the storage tank 1. To ensure the stable operation of the overall structure during the mixing process, two sets of fixed arc plates 36 are installed at the top of the partition 31. The fixed arc plates 36 are symmetrically distributed on the front and rear sides of the inlet and outlet of the storage tank 1. While providing protection, they do not affect the entry and exit of materials. Multiple sets of mounting cylinders 37 are embedded in the fixed arc plates 36. Each set of mounting cylinders 37 is connected to a compression spring 38. A connecting rod 39 connected to the compression spring 38 is slidably connected inside the mounting cylinder 37. A protective arc plate 310 is installed at the outer end of the multiple sets of connecting rods 39. The protective arc plate 310 is made of silicone elastic material. When the storage tank 1 shakes, it absorbs the impact force through its own deformation. In conjunction with the internal compression spring 38, it further enhances the buffering effect. This not only reduces the impact of vibration on the storage tank 1, but also avoids wear caused by rigid contact between the protective structure and the storage tank 1, thus extending the service life of the equipment. During the mixing process, the mixing process can easily cause the material to collide with the storage tank 1, resulting in vibration. The buffer spring 34 can buffer the longitudinal vibration, and the symmetrically distributed dampers 35 further absorb the vibration energy and suppress the shaking. When the storage tank 1 shakes, the protective arc plate 310 is pushed by the connecting rod 39 to compress the spring 38. The spring deformation absorbs the lateral impact force, thereby reducing the overall vibration, reducing noise, and protecting the equipment from damage.
