Technical Field
[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a special rotating basket for washing baskets. Background Technology
[0002] In the field of industrial cleaning, especially for the automated cleaning of material baskets (hereinafter referred to as "wash baskets") used in the food, pharmaceutical, and electronics industries, a rotating basket driven by a motor is typically used to rotate the basket, which is installed inside the cleaning chamber. The basket is pushed into the rotating basket by a feeding mechanism (such as a cylinder), and then the motor drives the basket to rotate, where it receives water, cleaning agents, rinsing agents, and drying airflow within the cleaning chamber.
[0003] Existing technologies (such as) Figure 1As shown, the existing rotating basket includes a rear connecting flange 1, a front connecting flange 2, and a support assembly 3 located between the rear connecting flange 1 and the front connecting flange 2. The rear connecting flange 1 has a motor mounting hole 11 for connecting a motor. The support assembly 3 includes a first slide rail shaft 31 and a second slide rail shaft 32 that are parallel to each other and on the same plane; as well as a first positioning shaft 33, a second positioning shaft 34, a first guide shaft 35, a second guide shaft 36, a third guide shaft 37, a fourth guide shaft 38, a third positioning shaft 39, and a fourth positioning shaft 310. The first slide rail shaft 31, the second slide rail shaft 32, the first positioning shaft 33, the second positioning shaft 34, the first guide shaft 35, the second guide shaft 36, the third guide shaft 37, the fourth guide shaft 38, the third positioning shaft 39, and the fourth positioning shaft 310 together form a space for placing the washing basket. The existing rotating basket support structure 3 uses the parallel first slide rail shaft 31 and the second slide rail shaft 32 as the load-bearing and sliding track for the washing basket, and the first slide rail shaft 31 and the second slide rail shaft 32 are optical axes. This structure reveals several inherent flaws in practice: The bottom of the washing basket (usually a metal mesh or welding rod) and the smooth steel slide rail shafts exhibit typical sliding friction, with a high coefficient of friction resulting in significant frictional force. This means that pushing the washing basket into the rotating basket requires overcoming considerable frictional force. When the washing basket is pushed in, it is difficult for its bottom to achieve ideal line or surface contact with the first slide rail shaft 31 and the second slide rail shaft 32. In reality, due to manufacturing tolerances, slight deformation of the washing basket bottom, or installation errors, the contact points are often discontinuous and unevenly stressed. This causes the washing basket to bear an unbalanced frictional torque, leading to a tendency to deflect. Once the washing basket deflects slightly, its sidewalls will contact and press against the guide shafts of the rotating basket (such as the first guide shaft 35). At this point, the lateral resistance generated by sliding friction will quickly offset the pushing force of the feeding cylinder, creating a self-locking effect, thus causing the washing basket to completely jam. Jamming not only causes production interruptions, but frequent jamming impacts can also damage the washing basket, guide shafts, and even the feeding cylinder. Sliding friction will continuously wear down the bottom of the washing basket and the slide rail shaft. After long-term use, the gap will increase, further aggravating the risk of unstable operation and increasing the maintenance cost and frequency of spare parts replacement.
[0004] In summary, the root cause of the existing technical problems lies in the use of sliding friction in the support structure. Therefore, it is urgent to improve the rotating basket structure to solve the jamming problem caused by sliding friction. Utility Model Content
[0005] The purpose of this invention is to solve the jamming problem caused by sliding friction between the existing rotating basket and the washing basket.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a special rotating basket for washing baskets, comprising a rear connecting flange, a front connecting flange, and a support assembly connected between the rear connecting flange and the front connecting flange. A first roller group and a second roller group are spaced apart in the bottom area of the support assembly. The first roller group includes a long strip-shaped first roller mounting plate and a plurality of first rollers arranged at equal intervals along the length of the first roller mounting plate. The second roller group includes a long strip-shaped second roller mounting plate and a plurality of second rollers arranged at equal intervals along the length of the second roller mounting plate. Both the first roller mounting plate and the second roller mounting plate are installed between the rear connecting flange and the front connecting flange, and the rolling surfaces formed by the first rollers and the second rollers contact the bottom of the washing basket and undergo rolling friction. The middle area of the support assembly includes a first guide shaft and a second guide shaft located above the outer sides of the first roller group and the second roller group, respectively. A third guide shaft and a fourth guide shaft are also provided above the first guide shaft and the second guide shaft, and the first guide shaft, the second guide shaft, the third guide shaft, and the fourth guide shaft limit the side of the washing basket.
[0007] Preferably, the first roller and the second roller are nylon wheels, polyurethane wheels, or rubber-coated bearing wheels.
[0008] Preferably, the top area of the support assembly is further provided with a third positioning shaft and a fourth positioning shaft for limiting the top of the washing basket.
[0009] Preferably, both ends of the first guide shaft, the second guide shaft, the third guide shaft and the fourth guide shaft are welded to the rear connecting flange and the front connecting flange, respectively.
[0010] Preferably, the support assembly also includes a bottom limiting rod, with both ends of the bottom limiting rod connected to the bottom of the rear connecting flange and the front connecting flange, respectively; and the bottom limiting rod is located below the center of the line connecting the first roller group and the second roller group. The bottom limiting rod is used to support the washing basket from the bottom and prevent the washing basket from jumping or derailing in the vertical direction.
[0011] Preferably, the rear connecting flange has a motor mounting hole for installing the drive motor.
[0012] Preferably, the front connecting flange has a first front mounting hole corresponding to the first roller mounting plate and a second front mounting hole corresponding to the second roller mounting plate; the rear connecting flange has a first rear mounting hole corresponding to the first roller mounting plate and a second rear mounting hole corresponding to the second roller mounting plate.
[0013] Preferably, the first roller and the second roller are rotatably connected to the first roller mounting plate and the second roller mounting plate respectively via roller shafts.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows: The coefficient of friction for rolling friction is much lower than that for sliding friction, which greatly reduces the resistance to pushing the washing basket. The feeding cylinder requires only a small amount of thrust to easily push the washing basket, ensuring smooth operation and eliminating jamming. The rolling supports provided by the first and second roller sets are highly tolerant of flatness errors at the bottom of the washing basket. Even if the bottom of the washing basket is uneven, the rollers can adapt and adjust, maintaining a low-resistance state. The reliability of continuous equipment operation is improved.
[0015] The first and second roller sets are arranged in parallel, naturally forming a track that corrects the direction of the washing basket. Combined with the directional shafts on both sides, this ensures the washing basket runs smoothly in a straight line, without deviation or wobbling, thus facilitating subsequent cleaning processes. Rolling friction significantly reduces wear on the bottom of the washing basket and supporting components, extending their service life and reducing the frequency of spare parts replacement and maintenance workload.
[0016] Simply replacing the frequently malfunctioning slide rail shafts with the first and second roller sets requires no major modifications to the main body of the rotating basket. Therefore, this solution has extremely low modification costs, is easy to implement, and has good compatibility with existing cleaning equipment. Attached Figure Description

[0018] The main technical solutions of the existing technology are as follows Figure 1As shown, the rear connecting flange 1 is provided with a motor mounting hole 11 for mounting a drive motor; the front connecting flange 2 and the rear connecting flange 1 are connected by a support assembly 3; the support assembly 3 includes a first slide rail shaft 31, a second slide rail shaft 32, a first positioning shaft 33, a second positioning shaft 34, a first guide shaft 35, a second guide shaft 36, a third guide shaft 37, a fourth guide shaft 38, a third positioning shaft 39, and a fourth positioning shaft 310; the third positioning shaft 39 and the fourth positioning shaft 310 limit the top of the washing basket, and the first guide shaft 35, the second guide shaft 36, the third guide shaft 37, and the fourth guide shaft 38 provide guidance and limit the movement of the washing basket on both sides; the first slide rail shaft 31 and the second slide rail shaft 32 limit the bottom of the washing basket and serve as the track for the movement of the washing basket. When the feeding cylinder pushes the washing basket into the rotating basket, the first slide rail shaft 31 and the second slide rail shaft 32 contact the bottom of the washing basket. The first slide rail shaft 31, the second slide rail shaft 32 and the bottom of the washing basket are in sliding friction. Uneven force on the bottom of the washing basket may cause the washing basket to get stuck.
[0019] The main purpose of this invention is to improve the problem of jamming when pushing a material-carrying washing basket into the existing rotating basket. Figures 2-5As shown, a special rotating basket for washing baskets includes a rear connecting flange 1, a front connecting flange 2, and a support assembly 3 connecting the rear connecting flange 1 and the front connecting flange 2. The rear connecting flange 1 and the front connecting flange 2 serve as supports at both ends of the rotating basket. The rear connecting flange 1 has a motor mounting hole 11 for installing a drive motor, transmitting the motor torque to the entire rotating basket. This utility model removes the first slide rail shaft 31, the second slide rail shaft 32, the first positioning shaft 33, and the second positioning shaft 34 from the traditional rotating basket, replacing them with a first roller group 5 and a second roller group 6. The first roller group 5 and the second roller group 6 are spaced apart in the bottom area of the support assembly 3. The first roller group 5 and the second roller group 6 are the core of this solution. They convert the sliding friction interface into a rolling friction interface, supporting the entire weight of the washing basket with extremely low frictional resistance, forming two reliable rolling tracks to guide the linear movement of the washing basket. The thrust of the feeding cylinder is efficiently converted into the smooth rolling forward of the washing basket. The first roller group 5 includes a long strip-shaped first roller mounting plate 51 and a plurality of first rollers 52 arranged at equal intervals along the length of the first roller mounting plate 51; the second roller group 6 includes a long strip-shaped second roller mounting plate 61 and a plurality of second rollers 62 arranged at equal intervals along the length of the second roller mounting plate 61; both the first roller mounting plate 51 and the second roller mounting plate 61 are installed between the rear connecting flange 1 and the front connecting flange 2; specifically, the front connecting flange 2 has a first front mounting hole 21 corresponding to the first roller mounting plate 51 and a second front mounting hole 22 corresponding to the second roller mounting plate 61; the rear connecting flange 1 has a first rear mounting hole 12 corresponding to the first roller mounting plate 51 and a second rear mounting hole 13 corresponding to the second roller mounting plate 61; the first roller mounting plate 51 and the second roller mounting plate 61 ensure that the rollers in the same group are on a straight line and at the same height, thus ensuring the stability of the support. The rolling surfaces formed by the first roller 52 and the second roller 62 contact the bottom of the washing basket and experience rolling friction. The first roller 52 and the second roller 62 can be nylon wheels, polyurethane wheels, or rubber-coated bearing wheels. The first roller 52 and the second roller 62 are rotatably connected to the first roller mounting plate 51 and the second roller mounting plate 61, respectively, via roller shafts 7. The roller shaft 7 must ensure a proper fit tolerance with the inner bore of the rollers to allow for flexible rotation of the corresponding rollers.
[0020] The central region of the support assembly 3 includes a first guide shaft 35 and a second guide shaft 36 located above the outer sides of the first roller group 5 and the second roller group 6, respectively. Above the first guide shaft 35 and the second guide shaft 36, a third guide shaft 37 and a fourth guide shaft 38 are also provided. These guide shafts limit the side movement of the washing basket, preventing lateral displacement and shaking during rotation. The top region of the support assembly 3 also includes a third positioning shaft 39 and a fourth positioning shaft 310, spaced apart, for limiting the top of the washing basket. Both ends of the first guide shaft 35, the second guide shaft 36, the third guide shaft 37, and the fourth guide shaft 38 are welded to the rear connecting flange 1 and the front connecting flange 2, respectively. The support assembly 3 also includes a bottom limiting rod 4, with both ends of the bottom limiting rod 4 connected to the bottom of the rear connecting flange 1 and the front connecting flange 2 respectively; and the bottom limiting rod 4 is located below the center of the line connecting the first roller group 5 and the second roller group 6. The bottom limiting rod 4 is used to support the washing basket from the bottom and prevent the washing basket from jumping or derailing in the vertical direction.
[0021] like Figure 3 , Figure 4 , Figure 5 As shown, the improved design includes a first rear mounting hole 12 and a second rear mounting hole 13 added to the rear connecting flange 1; a first front mounting hole 21 and a second front mounting hole 22 added to the front connecting flange 2; the two ends of the first roller mounting plate 51 are respectively connected to the first rear mounting hole 12 and the first front mounting hole 21; the two ends of the second roller mounting plate 61 are respectively connected to the second rear mounting hole 13 and the second front mounting hole 22. Six first rollers 52 are rotatably connected to the first roller mounting plate 51 via six roller shafts 7; six second rollers 62 are rotatably connected to the second roller mounting plate 61 via six roller shafts 7; a first guide shaft 35 and a third guide shaft 37 are provided above the outer side of the first roller group 5; a second guide shaft 36 and a fourth guide shaft 38 are provided above the outer side of the second roller group 6; a third positioning shaft 39 and a fourth positioning shaft 310 are spaced apart between the top of the rear connecting flange 1 and the top of the front connecting flange 2; a bottom limiting rod 4 is provided between the bottom of the rear connecting flange 1 and the bottom of the front connecting flange 2. The improved structure removes the original first slide rail shaft 31, second slide rail shaft 32, first positioning shaft 33 and second positioning shaft 34; and replaces them with first roller group 5 and second roller group 6; the washing basket enters the rotating basket along the first roller group 5 and the second roller group 6, and the rolling friction of the rollers is less than the original sliding friction to improve the problem of the washing basket getting stuck when entering the rotating basket.
[0022] In use, the washing basket is pushed horizontally into the rotating basket by the feeding cylinder (or pushing mechanism). The bottom of the washing basket first contacts the rollers on the first roller group 5 and the second roller group 6. As the cylinder continues to advance, the weight of the washing basket is supported by the rollers, and the original sliding friction is converted into rolling friction, greatly reducing the pushing resistance. The washing basket moves forward smoothly under the drive of the rollers, while its sides are guided and limited by the first guide shaft 35, the second guide shaft 36, the third guide shaft 37, and the fourth guide shaft 38, ensuring that it moves in a straight line without deviating. The top of the washing basket is restricted from moving upward by the third positioning shaft 39 and the fourth positioning shaft 310, while the bottom is supported by the bottom limiting rod 4 to prevent it from jumping or derailing during operation. The entire pushing process is smooth and stable, effectively avoiding the jamming problem caused by sliding friction in traditional structures.
[0023] This utility model provides a special rotating basket for washing baskets. By improving the support components of the rotating basket, it replaces the traditional sliding friction. The parallel arrangement of the first roller group 5 and the second roller group 6 serves as the load-bearing and conveying track for the washing basket. The rolling support provided by the first roller group 5 and the second roller group 6 has strong tolerance for flatness errors at the bottom of the washing basket. Even if the bottom of the washing basket is uneven, the rollers can adapt and adjust, maintaining a low-resistance state. The reliability of continuous operation of the equipment is improved. This solution transforms the original sliding friction into rolling friction during the washing basket's advancement, solving the problem of washing basket jamming caused by high sliding friction and uneven force. The first roller group 5, the second roller group 6, and the bottom limiting rod 4, together with the original guide shaft and positioning shaft, constitute a low-resistance, high-stability washing basket operating environment. The parallel arrangement of the first roller group 5 and the second roller group 6 forms a track, which has a corrective effect on the washing basket. Combined with the directional shafts on both sides, it ensures that the washing basket runs smoothly in a straight line without deviation or shaking, providing conditions for subsequent cleaning processes. Rolling friction significantly reduces wear on the bottom of the washing basket and supporting components, extending their service life and reducing the frequency of spare parts replacement and maintenance workload. This invention not only improves the smoothness of equipment operation, but also simplifies the structural modification by adding the first roller group 5, the second roller group 6, and the bottom limit rod 4, resulting in minimal increase in manufacturing costs and facilitating its adoption on existing equipment.
