Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and specifically to a basket cover clamping mechanism for a tilting cleaning machine. Background Technology

[0002] In a typical cleaning production line, small parts are usually loaded into a basket, the basket cover is manually fastened, and the basket is placed on the cleaning line. After cleaning, the buckle is manually opened and the material is unloaded.

[0003] The automatic cleaning line uses an automatic lid clamping mechanism. Its feature is that the basket itself does not have a lid. The lid is on the rotating drum inside the equipment. One structure is that the lid is fixed to the grid plate. The grid plate has four oblong inclined slides. The slides are equipped with spring-loaded drive shafts. When in use, external power is applied to the drive shafts, and the drive shafts move in the slides to open and close the basket lids.

[0004] The existing structure locks the basket by pressing the drive shaft with a spring. However, the spring pressure is limited, and when the weight of the basket and the impact force of the flipping exceed the spring pressure, the pressure cap will fail. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a basket cover clamping mechanism for a tilting washing machine, which can solve the problem of basket cover failure due to excessive weight and impact force.

[0006] This invention is achieved through the following technical solution: A basket cover clamping mechanism for a tilting washing machine is provided, comprising: Drive rod assembly, used to receive external power; The basket cover is used to secure the basket rim. The linkage mechanism, hinged between the drive rod assembly and the basket cover, converts the linear motion of the drive rod assembly into the lifting motion of the basket cover. The elastic element acts on the drive rod assembly to provide a restoring force; The linkage mechanism includes an upper linkage, a lower linkage, and a drive linkage that are hinged together by a pin. The upper linkage is hinged to the rotating drum of the equipment through a connecting mechanism, the lower linkage is hinged to the basket cover, and the drive linkage is connected to the drive rod assembly. When the cover is closed and pressed, the upper and lower connecting rods move to a collinear or nearly collinear position under the drive of the drive rod assembly and the elastic element, forming a self-locking structure.

[0007] Furthermore, it also includes guide wheels, which are mounted on the basket cover via pins, and guide plates are vertically fixed at both ends of the equipment drum for engaging with the guide wheels.

[0008] By setting guide wheels, which are rotatably mounted on the basket cover via wheel frames and pins, and abutting against the guide plates on both sides of the equipment's rotating drum, the basket cover can roll along the surface of the guide plates when it is raised or lowered. This not only ensures the stability of the basket cover's raising and lowering, but also limits the raising and lowering of the basket cover, ensuring the stability of opening and closing.

[0009] Furthermore, the connecting mechanism includes a fixed rod, a fixed seat, and a fixed shaft. The two ends of the fixed rod are vertically fixed between the two guide plates. The fixed seat is connected to the fixed rod. The fixed shaft is fixed to the fixed seat, located above the fixed rod and perpendicular to the fixed rod. The upper end of the upper connecting rod is hinged to the fixed shaft.

[0010] A fixed seat is installed on the fixed rod of the connecting mechanism. The fixed seat is connected to the fixed shaft and is hinged to the upper connecting rod. When the upper and lower connecting rods rotate, the upper connecting rod can be positioned by the connecting mechanism, thus solving the connection problem between the upper connecting rod and the rotating drum of the equipment.

[0011] Furthermore, the drive rod assembly includes a main drive rod and a secondary drive rod located on at least one side of the main drive rod. The main drive rod is movably mounted between two guide plates. An elastic element is installed between one end of the main drive rod and one of the guide plates, and the other end of the main drive rod is used to receive external driving force. The secondary drive rod is vertically connected to one side of the main drive rod and is hinged to the drive link of the linkage mechanism.

[0012] The main drive rod is movably connected between the two guide plates with the help of an elastic element, which allows the main drive rod to move linearly by external force. The auxiliary drive rod is vertically connected to the main drive rod and is used to transmit the force of the main drive rod and cooperate with the linkage mechanism to perform actions.

[0013] Furthermore, the auxiliary drive rods are vertically connected to both sides of the main drive rod and are symmetrically arranged. Each auxiliary drive rod has a linkage mechanism at its end, which is hinged to the drive linkage of the linkage mechanism.

[0014] The auxiliary drive rods are symmetrically installed on both sides of the main drive rod, which ensures that the force is evenly distributed on both sides of the basket cover and improves the stability of the basket cover's lifting and opening.

[0015] Furthermore, the elastic element is a return spring sleeved on the main drive rod.

[0016] When the cover is opened, external power pushes the main drive rod to compress the return spring, and drives the linkage mechanism to move through the auxiliary drive rod, making the included angle between the upper and lower linkages smaller and lifting the cover; when the cover is closed, external power is removed, the return spring returns to its original position, and the drive rod assembly moves in the opposite direction, making the upper and lower linkages tend to be collinear to achieve self-locking and clamping.

[0017] Furthermore, the basket cover includes a cover plate and a grid plate fixed to the cover plate. Water-permeable holes are evenly opened on the cover plate, and the lower connecting rod and guide wheel are both hinged to the grid plate.

[0018] The cover plate and the grating plate are connected to form a basket cover. The cover plate has evenly spaced water-permeable holes for drainage. The grating plate is used to connect the lower connecting rod and the guide wheel, so as to facilitate lifting and opening and closing in cooperation with the linkage mechanism.

[0019] The beneficial effects of this invention are: When the cover is closed and pressed, the present invention uses the cooperation of the drive rod and the spring to move the upper and lower connecting rods to a collinear or nearly collinear "dead point" position. At this position, the mechanism will generate a self-locking effect, and the upward impact force of the basket will be converted into an axial force inside the connecting rod, rather than the force that pushes the cover open. This means that the locking force no longer depends on the limited spring force, but is determined by the structural strength of the mechanism itself, thus being able to withstand several times the weight and impact force of the previous one, fundamentally solving the risk of cover failure.

[0020] Thanks to its self-locking structure, this mechanism maintains a locked basket cover even under the harsh conditions of high-speed rotation of the cleaning machine, greatly improving the stability and reliability of the entire cleaning production line and reducing downtime caused by cover failure. The guide wheels within the mechanism engage with the guide surfaces on the rotating drum, ensuring precise and smooth movement of the basket cover during opening and closing. This effectively prevents the basket cover from shifting or jamming during lifting, reducing wear and the failure rate.

[0021] The entire opening and clamping process is automatically completed by the power mechanism, requiring no manual intervention. This perfectly meets the needs of automated cleaning lines, improving production efficiency and reducing labor costs and safety risks. Once the mechanical self-locking mechanism is in place, it will not loosen due to accidental impact unless actively unlocked, providing a high level of safety for the equipment and materials. Meanwhile, the spring's primary role in the new structure has shifted to providing reset force and ensuring the self-locking mechanism is in place, rather than bearing the main impact load. This improves its working environment and extends its service life.

[0022] In summary, this invention solves the problem of cap failure caused by excessive weight and impact force of the basket; by using the mechanism of this invention on the rotating drum of a fully automatic flipping and cleaning machine, it automatically caps and presses open baskets, preventing internal parts from falling out during flipping, replacing the manual capping operation, and improving the level of automation and production efficiency.

[0028] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0029] A basket cover clamping mechanism for a tilting washing machine includes: A drive rod assembly is used to receive external power; the drive rod assembly includes a main drive rod 1 and a secondary drive rod 2 located on at least one side of the main drive rod 1. In this embodiment, the secondary drive rods 2 are vertically connected to both sides of the main drive rod 1 and symmetrically arranged. Each secondary drive rod 2 has a linkage mechanism at its end, which is hinged to the drive link 4 of the linkage mechanism. Figure 1 As shown, two auxiliary drive rods 2 are respectively arranged on both sides of the main drive rod 1. Both auxiliary drive rods 2 on the same side are connected to the fixed rod 12 of the same connecting mechanism through a linkage mechanism.

[0030] The main drive rod 1 is movably mounted between the two guide plates 11. An elastic element is installed between one end of the main drive rod 1 and one of the guide plates 11, and the other end of the main drive rod 1 is used to receive external driving force. The auxiliary drive rod 2 is vertically connected to one side of the main drive rod 1 and is hinged to the drive link 4 of the linkage mechanism.

[0031] The basket cover 8 is used to press the basket. The basket cover 8 includes a cover plate 81 and a grid 82 fixed on the cover plate 81. Water-permeable holes 83 are evenly opened on the cover plate 81. The lower connecting rod 6 and the guide wheel 9 are both hinged to the grid plate 82.

[0032] A linkage mechanism, hinged between the drive rod assembly and the basket cover 8, converts the linear motion of the drive rod assembly into the lifting motion of the basket cover 8. The linkage mechanism includes an upper connecting rod 5, a lower connecting rod 6, and a drive connecting rod 4, which are hinged together by a pin 7. The upper connecting rod 5 is hinged to the rotating drum 10 of the equipment through a connecting mechanism, the lower connecting rod 6 is hinged to the basket cover 8, and the drive connecting rod 4 is connected to the drive rod assembly. The connecting mechanism includes a fixed rod 12, a fixed seat 13, and a fixed shaft 14. The two ends of the fixed rod 12 are vertically fixed between the two guide plates 11. The fixed seat 13 is connected to the fixed rod 12. The fixed shaft 14 is fixed to the fixed seat 13, located above the fixed rod 12 and perpendicular to the fixed rod 12. The upper end of the upper connecting rod 5 is hinged to the fixed shaft 14.

[0033] An elastic element acts on the drive rod assembly to provide a restoring force; the elastic element is a return spring 3 sleeved on the main drive rod 1; when the cover is opened, external power pushes the main drive rod 1 to compress the return spring 3, and drives the linkage mechanism to move through the auxiliary drive rod 2, so that the included angle between the upper linkage 5 and the lower linkage 6 becomes smaller, and the basket cover 8 is lifted; when the cover is closed, the external power is removed, the return spring 3 returns to its original position, and the drive rod assembly moves in the opposite direction, so that the upper linkage 5 and the lower linkage 6 tend to be collinear to achieve self-locking and pressing.

[0034] When the cover is closed and pressed, the upper connecting rod 5 and the lower connecting rod 6 move to a collinear or nearly collinear position under the drive of the drive rod assembly and the return spring 3, forming a self-locking structure.

[0035] It also includes guide wheels 9, which are mounted on the basket cover 8 via pins 7. Guide plates 11 are vertically fixed at both ends of the equipment drum 10 for engaging with the guide wheels 9.

[0036] The working process of this invention is divided into two processes: opening the lid to loosen it and closing the lid to tighten it.

[0037] The opening and releasing process is as follows: external power pushes the main drive rod 1, the return spring 3 begins to compress, and the four auxiliary drive rods 2 drive the drive connecting rods 4 connected to them to move together, thereby making the angle between the upper connecting rod 5 and the lower connecting rod 6 gradually decrease. The lower connecting rod 6 drives the basket cover 8 to rise through the pin 7, realizing the opening and releasing action.

[0038] The closing and pressing process is as follows: by removing the external power acting on the main drive rod 1, the return spring 3 gradually returns to its original position, driving the auxiliary drive rod 2 and the drive connecting rod 4 to move together, thereby driving the upper connecting rod 5 and the lower connecting rod 6 to move. The upper connecting rod 5 and the lower connecting rod 6 eventually become collinear, forming a self-locking structure. The connecting rod self-locking mechanism can withstand greater weight and impact force. The lower connecting rod 6 drives the basket cover 8 to press down through the pin 7, realizing the closing and pressing action.
