Description

Technical Field

[0001] This utility model relates to the field of washing machine manufacturing technology, and in particular to a cutting device with adjustable inner tub size for washing machines. Background Technology

[0002] The inner drum of a washing machine is the core load-bearing component of the washing machine. It is mainly used to hold clothes and complete the rotation and spin-drying actions in conjunction with the washing program. It is usually made of high-strength plastic or stainless steel, molded, and then trimmed at the edges, adjusted in height, or cut into a specific shape through a cutting process to meet the assembly size requirements of different washing machine models. In the production process of washing machine inner tubs, the cutting device is a key piece of equipment for achieving precise control of the inner tub size. Its main function is to cut, trim, or shape the formed inner tub blank according to the preset size, ensuring that parameters such as the inner tub's diameter, height, and edge flatness meet the assembly standards, and avoiding the problem of the inner tub not matching the washing machine shell, motor, and other components due to size deviations.

[0003] The existing adjustable cutting device for washing machine inner tub has the following shortcomings: Existing equipment lacks a lifting and limiting structure adapted to inner tubs of different diameters. It only limits the left end of the inner tub with a single baffle. The left end of the inner tub is prone to sagging due to lack of support, causing the inner tub axis to tilt and resulting in deviations in cutting length. Furthermore, it cannot adjust the lifting position according to the inner tub diameter, resulting in poor adaptability. The inner tub fixing structure of existing equipment is mostly single-sided or double-sided clamping, and the clamping force is difficult to control evenly. After fixing, the inner tub is prone to displacement due to radial force during cutting, resulting in uneven cutting edges. At the same time, the fixing structure is cumbersome to adjust and cannot be quickly adapted to inner tubs of different diameters, affecting production efficiency. Utility Model Content

[0004] This utility model mainly provides a washing machine inner tub cutting device with adjustable cutting size, featuring adaptive lifting and limiting function, stable inner tub fixing, and high cutting precision.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a washing machine inner tub cutting device with adjustable cutting size, including a support base, a limiting bracket slidably connected to the top left side of the support base, an annular fixing frame fixedly connected to the top right side of the support base, and a cutting component rotatably connected to the right side of the annular fixing frame.

[0006] The limiting bracket includes a sliding baffle. A sliding groove is formed on the top left side of the support base. The bottom of the outer surface of the sliding baffle is slidably connected to the inner surface of the sliding groove. A first threaded rod is threaded to the bottom of the sliding baffle. A second sliding groove is formed on both the front and rear sides of the upper part of the sliding baffle. A second threaded rod is rotatably connected to the middle of the second sliding groove. A support column is threaded to the outer surface of the second threaded rod. The right end of the support column extends to the right side of the sliding baffle.

[0007] Preferably, the left end of the support base is fixedly connected to the first motor, the output shaft of the first motor passes through the interior of the sliding groove and is fixedly connected to the middle of the first screw, and the top end of the second screw passes through the top of the sliding baffle and is fixedly connected to the knob.

[0008] Preferably, the annular fixing frame includes an annular connecting plate, which is fixedly connected to the top right side of the support base. Four U-shaped sliding plates are slidably connected to the outer surface of the annular connecting plate. One end of the U-shaped sliding plate near the annular connecting plate extends through to the inner side of the annular connecting plate. A third screw is rotatably connected to the middle of the U-shaped sliding plate. A second motor is fixedly connected to the side of the U-shaped sliding plate away from the annular connecting plate. The output shaft of the second motor extends through to the inner side of the U-shaped sliding plate and is fixedly connected to the middle of the third screw.

[0009] Preferably, the outer surface of the third screw is threaded to a threaded slider, the threaded slider is fixedly connected to the outer surface of the annular connecting plate, and the left and right sides of the end of the U-shaped slide away from the second motor are fixedly connected to arc arms, and the upper and lower ends of the arc arms are rotatably connected to a clamping wheel.

[0010] Preferably, the cutting assembly includes a rotating ring rotatably connected to the right side of an annular connecting plate, an electric push rod is fixedly connected to the top right side of the rotating ring, and the output end of the electric push rod is fixedly connected to a cutting machine.

[0011] Preferably, a rotating gear ring is fixedly connected to the left side of the rotating ring, a drive motor is fixedly connected to the top of the outer surface of the annular connecting plate, the output shaft of the drive motor is fixedly connected to a transmission wheel, and the outer surface of the transmission wheel meshes with the outer surface of the rotating gear ring.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. In this utility model, through the cooperation between the sliding baffle, the first screw, the second screw, and the support column of the limiting bracket, the first motor drives the first screw to rotate, causing the sliding baffle to move left and right along the sliding groove one, and the sliding baffle abuts against the left end of the inner barrel to achieve axial limitation; at the same time, rotating the knob drives the second screw to rotate, causing the support column to move back and forth along the sliding groove two, and the left end of the inner barrel rests on the support column to achieve support. On the one hand, the movement of the sliding baffle can accurately control the cutting length of the inner barrel and avoid length deviation; on the other hand, the front and rear positions of the support column can be adjusted according to the diameter of the inner barrel to ensure that the support column can stably support inner barrels of different diameters, prevent the left end of the inner barrel from drooping and causing the axis to tilt, improve cutting accuracy, and at the same time, adjustment can be completed without disassembling parts, significantly improving adaptability and ease of operation.

[0013] 2. In this utility model, through the cooperation of the circular fixed frame's U-shaped sliding plate, third screw, second motor, arc arm, and top clamping wheel, the second motor drives the third screw to rotate. Since the threaded slider is fixed on the circular connecting plate, when the third screw rotates, it drives the U-shaped sliding plate to move radially along the circular connecting plate. The U-shaped sliding plate drives the arc arm and top clamping wheel to move inward. The top clamping wheels on the four U-shaped sliding plates evenly press against the barrel wall from the circumference of the inner barrel. Firstly, the top clamping wheels in the four directions form a uniform clamping force, preventing the inner barrel from shifting due to uneven force, ensuring the stability of the inner barrel during the cutting process, and improving the flatness of the cutting edge. Secondly, the top clamping wheel is a rotating structure, which can reduce friction damage with the barrel wall. At the same time, through motor-driven adjustment, there is no need to manually twist multiple parts, which can quickly adapt to inner barrels of different diameters, greatly improving the fixing efficiency and reducing the labor intensity of operators.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Please see Figure 1 - Figure 4 This utility model provides a technical solution: an adjustable cutting device for the inner tub of a washing machine, including a support base 1, a limiting bracket 2 slidably connected to the top left side of the support base 1, an annular fixing frame 3 fixedly connected to the top right side of the support base 1, and a cutting assembly 4 rotatably connected to the right side of the annular fixing frame 3. The limiting bracket 2 includes a sliding baffle 21, a sliding groove 11 is opened on the top left side of the support base 1, the bottom of the outer surface of the sliding baffle 21 is slidably connected to the inner surface of the sliding groove 11, the bottom of the sliding baffle 21 is threadedly connected to a first screw 22 that passes through from left to right, a second sliding groove 24 that passes through from left to right is opened on both the front and rear sides of the upper part of the sliding baffle 21, a second screw 25 is rotatably connected to the middle of the second sliding groove 24, and a support column 27 is threadedly connected to the outer surface of the second screw 25. The right end of the support column 27 extends to the right side of the sliding baffle 21.

[0019] like Figure 2 As shown, the left end of the support base 1 is fixedly connected to the first motor 23. The output shaft of the first motor 23 passes through the interior of the sliding groove 11 and is fixedly connected to the middle of the first screw 22. The top end of the second screw 25 passes through the top of the sliding baffle 21 and is fixedly connected to the knob 26. Here, the first motor 23 provides power for the movement of the sliding baffle 21, eliminating the need to manually push the baffle and reducing the intensity of operation. The knob 26 facilitates manual fine-tuning of the position of the support column 27, taking into account the flexibility of automation and manual adjustment, and ensuring that the lifting position is accurately adapted to the inner barrel diameter.

[0020] like Figure 3As shown, the annular fixing frame 3 includes an annular connecting plate 31, which is fixedly connected to the top right side of the support base 1. Four U-shaped sliding plates 32 are slidably connected to the outer surface of the annular connecting plate 31. One end of the U-shaped sliding plate 32 near the annular connecting plate 31 extends through to the inner side of the annular connecting plate 31. A third screw 33 is rotatably connected to the middle of the U-shaped sliding plate 32. A second motor 34 is fixedly connected to the side of the U-shaped sliding plate 32 away from the annular connecting plate 31. The output shaft of the second motor 34 extends through to the inner side of the U-shaped sliding plate 32 and is fixedly connected to the middle of the third screw 33. Here, the four U-shaped sliding plates 32 are evenly distributed at 90° on the outer surface of the annular connecting plate 31, which can apply force synchronously from four directions around the inner circumference of the inner barrel, avoiding force imbalance caused by clamping on one or both sides. The second motor 34 directly drives the third screw 33, which can quickly realize the radial movement of the U-shaped sliding plate 32 compared to manual adjustment, thus improving the fixing efficiency.

[0021] like Figure 4 As shown, the outer surface of the third screw 33 is threadedly connected to the threaded slider 35, which is fixedly connected to the outer surface of the annular connecting plate 31. The left and right sides of the end of the loop slide plate 32 away from the second motor 34 are fixedly connected to the arc arms 36. The upper and lower ends of the arc arms 36 are rotatably connected to the top clamping wheel 37. Here, the cooperation between the threaded slider 35 and the third screw provides stable guidance for the movement of the loop slide plate 32, avoiding deviation during the movement. The curvature of the arc arm 36 is adapted to the curve of the outer wall of the inner barrel, which can increase the contact range between the top clamping wheel 37 and the barrel wall. The rotation characteristics of the top clamping wheel 37 can rotate synchronously with the slight displacement of the inner barrel during cutting, reducing friction damage to the barrel wall.

[0022] like Figure 3 As shown, the cutting assembly 4 includes a rotating ring 41, which is rotatably connected to the right side of the annular connecting plate 31. An electric push rod 45 is fixedly connected to the top right side of the rotating ring 41, and the output end of the electric push rod 45 is fixedly connected to the cutting machine 46. Here, the rotating ring 41 rotates around the axis of the annular connecting plate 31, which can drive the cutting machine 46 to cut along the circumferential trajectory of the inner barrel, ensuring that the cutting surface is perpendicular to the axis of the inner barrel. The electric push rod 45 can precisely control the feed depth of the cutting machine 46, adapting to plastic or stainless steel inner barrels of different thicknesses, avoiding damage to the saw blade due to excessive feed or incomplete cutting due to insufficient feed.

[0023] like Figure 3As shown, a rotating gear ring 42 is fixedly connected to the left side of the rotating ring 41, and a drive motor 44 is fixedly connected to the top of the outer surface of the annular connecting plate 31. The output shaft of the drive motor 44 is fixedly connected to the transmission wheel 43. The outer surface of the transmission wheel 43 meshes with the outer surface of the rotating gear ring 42. Here, the gear ring transmission structure has high transmission efficiency and strong stability, which can ensure that the rotating ring 41 rotates at a uniform speed and avoid uneven cutting edges caused by speed fluctuations during the cutting process. The drive motor 44 independently controls the rotating ring 41 and can adjust the speed according to the material of the inner barrel to improve the cutting adaptability.

[0024] The usage and working principle of this device are as follows: Before use, check the status of each component. According to the diameter of the inner tub to be cut, turn the knob 26 to drive the second screw 25 to rotate, so that the support column 27 moves along the sliding groove 24 to the appropriate distance. Then, according to the cutting length, start the first motor 23 to drive the first screw 22 to rotate, so that the sliding baffle 21 moves along the sliding groove 11. After preset the distance between the sliding baffle 21 and the annular fixing frame 3, turn off the first motor 23. Next, pass the right end of the inner tub through the annular connecting plate 31 of the annular fixing frame 3, and place the left end on the support column 27 with the end face in contact with the sliding baffle 21. Start the second motor 34 to drive the third screw 33 to rotate, so that the spiral slide plate 32 moves radially along the annular connecting plate 31, driving the arc arm 36 and the top clamping wheel 37 to clamp the outer wall of the inner tub, and then turn off the second motor 34. Subsequently... Start the cutting machine 46 to rotate the saw blade, start the electric push rod 45 to push the cutting machine 46 to the preset cutting depth, then start the drive motor 44 to drive the transmission wheel 43 to rotate, and drive the rotating ring 41 to rotate around the annular connecting plate 31 once through the rotating gear ring 42, and the saw blade completes the circumferential cutting; after cutting, turn off the drive motor 44 and the cutting machine 46, start the electric push rod 45 in reverse to reset the cutting machine 46, start the second motor 34 in reverse to release the top clamping wheel 37, and finally take out the inner bucket. The sliding baffle 21 forms a two-way positioning with the support column 27 and the four-way top clamping wheel 37 to prevent the inner bucket from shifting; the drive motor 44, transmission wheel 43, and rotating gear ring 42 drive the rotating ring 41 to rotate at a uniform speed, and cooperate with the electric push rod 45 to control the cutting depth to ensure that the saw blade accurately cuts along the circumference of the inner bucket and adapts to inner buckets of different diameters and thicknesses.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
