Description

Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and more specifically to a barrel pressing mechanism for a barrel washing machine. Background Technology

[0002] Trash cans are daily necessities, especially in public areas. After use, stains often remain on their inner and outer walls, requiring regular collection and cleaning to reduce their environmental impact. Cleaning machines play a crucial role in this process. To prevent water accumulation inside the can after cleaning, an additional step of turning the can over is usually added before washing, by placing the trash can upside down with the opening facing downwards.

[0003] Meanwhile, trash cans are typically cleaned using a combination of rotating brushes and high-pressure water guns. If they are not securely held in place, they may bounce and tilt during the cleaning process. When the high-pressure water jets are applied, the force can reach 200 to 500 kilograms, potentially causing the trash can to get caught in the equipment, posing a safety hazard. Furthermore, the trash cans are easily displaced during the cleaning process due to the rotating brushes and the impact of the high-pressure water jets. If the trash cans shift during cleaning, interference will not only affect the transfer between subsequent workstations but also reduce the cleaning effectiveness.

[0004] Therefore, there is an urgent need for a mechanism that automatically presses the trash can at the cleaning station during the cleaning process and automatically releases it when the trash can moves to the inlet / outlet, and this mechanism will not hinder the normal entry, exit and cleaning of the trash can. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a drum pressing mechanism for a drum washing machine to solve the aforementioned problems.

[0006] This invention provides the following technical solution: A drum pressing mechanism for a drum washing machine includes: A central shaft, with mounting brackets and a turntable at its upper and lower ends respectively; A clamping plate, one end of which is hinged to a mounting bracket, and a tension spring connecting the clamping plate and the mounting bracket, wherein the elastic force of the tension spring drives the clamping plate to flip up or down to reset; The guide plate is fixed at an angle and is located on the path of the pressure plate rotating around the central axis; As the pressure plate rotates with the central shaft, it is limited by the guide plate and flips downward to press down on the upper surface of the trash can.

[0007] Preferably, it also includes a tipping mechanism, which is used to flip the trash can 180° and place it upside down on the turntable. During the process of the tipping mechanism driving the trash can to flip in the opposite direction from the turntable, it pushes up the pressing plate.

[0008] Preferably, the bottom of the free end of the clamping plate away from the mounting bracket is provided with a clamping flap.

[0009] Preferably, a support frame sealing plate is provided at the upper end of the central shaft, and multiple sets of turntable support frames are provided between the support frame sealing plate and the turntable, with the space between two adjacent sets of turntable support frames corresponding to a set of clamping plates.

[0010] Preferably, a first roller brush and a second roller brush are arranged radially along the turntable, with the first roller brush and the second roller brush located opposite each other on the trash can on the turntable; the first roller brush is coaxially and movably connected to the outside of the central shaft.

[0011] The present invention has the following beneficial technical effects: This invention achieves automatic opening and closing of the pressure barrel mechanism through a mechanical structure consisting of a pressure plate, a tension spring, and a guide plate. Combined with the rotational motion of a ring-shaped turntable, it avoids the high cost and susceptibility to failure associated with electromechanical structures.

[0012] During the rotation of the turntable, the pressing plate rotates and presses down under the action of the guide plate, automatically pressing the trash can. The trash can opening is inverted, and the bottom wall of the trash can does not need to be cleaned. This position is used for pressing the pressing plate, thereby avoiding affecting the cleaning effect of the trash can. As the tipping mechanism rotates the trash can 180° and moves it away from the top surface of the turntable, it simultaneously pushes the pressure plate to flip up at a certain angle, and under the action of the tension spring, the pressure plate flips up and resets.

Detailed Implementation

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Example: A drum pressing mechanism for a drum washing machine, such as Figures 1-5 As shown, it includes a turntable 41, a top plate 411, a central shaft 42, a support frame sealing plate 45, a guide plate 46, a mounting bracket 47, a pressure plate 48, and a tension spring 49.

[0017] The top plate 411 is fixedly set, the turntable 41 is coaxially fixedly connected to the lower end of the central shaft 42, and the upper end of the central shaft 42 is rotatably connected to the top plate 411. The turntable 41 is driven by a corresponding power device to rotate around the central shaft 42 as the axis center.

[0018] A support plate 45 is fixedly installed on the upper part of the central shaft 42. Multiple sets of turntable support frames 451 are arranged evenly around the central shaft 42 between the support plate 45 and the turntable 41. The upper part of the turntable 41 is divided into several work positions by the multiple turntable support frames 451, and each work position corresponds to a set of pressure barrel mechanism.

[0019] A mounting bracket 47 is fixedly installed below the support frame plate 45. A pressure plate 48 is hinged to the side wall of the mounting bracket 47 via a pressure shaft 482. A tension spring 49 is connected between the middle of the pressure plate 48 and the side wall of the mounting bracket 47. Each station (i.e., between two adjacent turntable support frames 451) corresponds to a set of pressure plates 48.

[0020] A guide plate 46 is fixedly installed on the bottom wall of the top plate 411. The guide plate 46 extends downward at an inclination from the bottom wall of the top plate 411 along the rotation direction of the turntable 41.

[0021] A first roller brush 43 is coaxially rotatably connected to the outer side of the central shaft 42. The first roller brush 43 is driven to rotate by a corresponding power mechanism. A second roller brush 44 is also installed on the top plate 411. The second roller brush 44 is located on the outer periphery of the turntable 41.

[0022] like Figure 5 As shown in state A1, the tension of spring 49 is at its maximum, and the pressure plate 48 cannot be suspended in a horizontal state. At this time, an upward or downward force can be applied to the pressure plate 48, so that the pressure plate 48 can be rotated upward or downward to reset.

[0023] Working principle: like Figures 1-2As shown, in normal conditions, the trash can 200 has its opening facing upwards. After being held in this state by the tipping mechanism 300, the trash can 200 is flipped 180° so that its opening faces downwards and it is placed on the upper surface of the turntable 41. The specific structure of the tipping mechanism 300 is not the focus of this solution and will not be described in detail.

[0024] Then, turntable 41 rotates the trash can 200 on it to the next workstation. During this process, the trash can that was originally in an upward-opening state (such as...) Figure 5 As shown in state B, it rotates and comes into contact with guide plate 46. Continuing to rotate, guide plate 46 pushes pressure plate 48 downwards (until...). Figure 5 (As shown in state C), the clamping plate 48 flips downward so that the clamping flange 481 at its free end abuts against the upper surface of the inverted trash can 200, thereby increasing the contact area with the upper surface of the inverted trash can 200 by the clamping flange 481. The pressing plate 48 presses down on the upper surface of the inverted trash can 200 and applies pressure through the tension spring 49.

[0025] When the compressed trash can 200 is rotated and cleaned by the first roller brush 43 and the second roller brush 44 on opposite sides, it will not shift in position, nor will it shift in position when rinsed by a high-pressure water gun.

[0026] The turntable 41 rotates once, causing the trash can 200 to pass through each station for different cleaning steps, finally returning to its initial position (i.e., near the tipping mechanism 300). The tipping mechanism 300 then clamps the trash can 200, which has been cleaned and is in an inverted position at the initial position of the turntable 41. The tipping mechanism 300 then rotates the clamped trash can 200 180° in the opposite direction to the ground, so that its opening faces upward. During this process, the trash can 200 pushes the pressure plate 48 on its upper surface to rotate upward a certain distance, which is sufficient to cross the horizontal position (e.g., ...). Figure 5 After reaching state A1, the clamping plate 48 is flipped upwards and reset by the elastic force of the tension spring 49. This ensures that the clamping plate 48 is in the initial upward position after the trash can 200 is released.

[0027] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
