Abstract
Description
Technical Field
[0001] This application relates to the field of workpiece cutting and bending manufacturing technology, and in particular to a rolling mill line for dishwasher rubber strip brackets. Background Technology
[0002] Among modern kitchen appliances, dishwashers, as efficient and convenient household appliances, have gained popularity among consumers. They not only significantly reduce the labor intensity of manual dishwashing but also improve the cleanliness and hygiene standards of tableware to a certain extent. However, the internal structure of a dishwasher is complex, and the fit and sealing between various components are crucial to its overall performance. The dishwasher door seal bracket, as a key connecting component between the dishwasher door and the inner tub, is typically designed to fix and support the sealing strip around the dishwasher door, ensuring that the door fits tightly against the inner tub when closed. This effectively prevents water, foam, and food residue from leaking out of the dishwasher during the washing process, maintaining the sealing and cleanliness of the washing environment.
[0003] In the production process of dishwasher sealing strip brackets, a key step is to precisely bend both ends of the bracket to form a stable U-shaped structure. This is crucial for ensuring a perfect fit between the bracket and the door sealing strip and for the overall structural stability. Currently, the equipment design for the sealing strip bracket bending process suffers from insufficient integration. Specifically, the cutting and bending operations are separated into two independent stages, requiring manual material handling and transfer. This not only increases labor costs but also hinders the transformation of the production process towards a more efficient integrated assembly line, limiting the potential for increased production efficiency. Existing bending equipment has limitations in its structural design. It generally employs an outer mold that presses the material and rotates it around an inner mold arc to complete the bending mechanism. If the rotation center of the outer mold and the center of the inner mold arc are not precisely aligned, the material will be obstructed during bending, preventing smooth rotation and leading to operational delays or even bending failures. This severely impacts the product yield and quality stability. Summary of the Invention
[0004] This device provides a roller milling line for dishwasher adhesive strip supports, and the specific implementation method is as follows:
[0005] For dishwasher adhesive strip support rolling line, including:
[0006] The cutting component and bending component are arranged sequentially along the conveying route of the rubber strip support. The cutting component is a hydraulically driven cutter that cuts strip-shaped materials from the rubber strip support to a fixed length.
[0007] Below the bending assembly is a mold seat that acts on the bottom of the strip material. The mold seat has rounded sides. The bending assembly includes a lifting structure and a second U-shaped seat. A seventh cylinder is provided on the second U-shaped seat.
[0008] The first U-shaped seat is rotatably provided on the inner side of the second U-shaped seat, and the arm end of the seventh cylinder is connected to the rotating shaft end of the first U-shaped seat through a flipping rod. A follower cylinder is provided on the outer side of the first U-shaped seat. The bending wheel is installed on the third U-shaped seat. The arm end of the follower cylinder passes through the inner side of the first U-shaped seat and is connected to the third U-shaped seat. The follower cylinder realizes the follower bending operation of the bending wheel along the arc direction of the mold seat end.
[0009] Based on the above technical solution, the rubber strip bracket is used as the material, and the bending wheel is fixed by the follower cylinder, that is, the bending wheel is in a floating state. During bending, the follower cylinder presses the bending wheel tightly against the end arc of the mold seat. When the center of rotation of the bending wheel deviates from the end arc of the mold seat, the bending wheel will float up and down. Under the pressure of the follower cylinder, the material is always pressed tightly against the end arc of the mold seat, resulting in excellent bending effect and less wear on the inner and outer molds, thus extending the life of the bending wheel.
[0010] Preferably, it also includes a frame for mounting the cutting component and the bending component, and a feed roller belt located at the front end of the cutting component for conveying the adhesive strip support.
[0011] Preferably, the cutting assembly further includes a second cylinder and a first base for mounting the hydraulic cylinder, the second cylinder being horizontally mounted on the frame, and the arm of the second cylinder being connected to the first base.
[0012] Based on the above technical solutions, by setting up a stable frame and a high-efficiency feeding roller belt, the integrated installation design of the cutting component and the bending component is realized, which greatly facilitates the subsequent process of cutting and bending various materials in a streamlined manner.
[0013] Preferably, the end of the mold base is provided with a support assembly for bending and tilting down to avoid obstacles, which includes a second base body and a support plate hinged to the second base body, and a third cylinder is connected between the two.
[0014] Based on the above technical solutions, by designing a first and second support component that can be flexibly tilted downwards, stable support for the long, straight rubber strip bracket is achieved during horizontal feeding. During bending operations, these two support components can be smoothly tilted downwards, thus avoiding the working area of the bending wheel and ensuring a smooth and unobstructed operation. The feeding roller belt is equipped with a limiting guide wheel for transporting the long, straight rubber strip bracket. An external rubber strip bracket feeding drive is provided outside the feeding roller belt, and the feeding drive is a conventional structure. A laser photoelectric detector can be added to the side of the mold base as a positioning reminder device and a zero-point detection device, further improving the convenience and safety of operation.
[0015] Preferably, the bending assembly further includes a third seat located at the top of the frame, on which a sixth cylinder is vertically mounted, and the arm of the sixth cylinder is connected to the second U-shaped seat.
[0016] Preferably, a guide rod is also provided vertically between the second U-shaped seat and the third seat.
[0017] Preferably, the third U-shaped seat and the first U-shaped seat have the same opening direction, and a slide rail is provided between them.
[0018] Based on the above technical solutions, the bending wheel was raised and lowered by setting a sixth cylinder, while the guide rod and slide rail further improved the stability of vertical lifting.
[0019] Preferably, a blanking component is provided at one side of the mold base, and a fourth cylinder is horizontally installed at the other side, with the arm end of the fourth cylinder corresponding to the blanking component.
[0020] Preferably, the unloading assembly includes a collecting rack hinged to the mold base, and a fifth cylinder is provided at the hinge point.
[0021] Based on the above technical solution, by setting up a material feeding component and a fourth cylinder, the automatic lateral discharge of the rubber strip bracket after bending is realized.
[0022] In summary, this application includes the following beneficial technical effects:
[0023] 1. In this utility model, the rubber strip bracket is used as the material, and the bending wheel is fixed by the follower cylinder, that is, the bending wheel is in a floating state. When bending, the follower cylinder presses the bending wheel tightly against the end arc of the mold seat. When the center of rotation of the bending wheel deviates from the end arc of the mold seat, the bending wheel will float up and down. Under the pressure of the follower cylinder, the material is always pressed tightly against the end arc of the mold seat, resulting in excellent bending effect and less wear on the inner and outer molds, thus extending the life of the bending wheel.
[0024] 2. This utility model achieves horizontal feeding support for the long straight rubber strip bracket by setting up a first support component and a second support component that can be flipped down. During the bending operation, the first support component and the second support component flip down to avoid obstacles to the bending wheel.
[0025] 3. This utility model has a simple structure. By setting up a material feeding component and a fourth cylinder, it realizes the automatic lateral discharge of the rubber strip bracket after bending. Attached Figure Description

[0042] The following is in conjunction with the appendix Figure 1-10 This application will be described in further detail.
[0043] This application discloses a roller milling line for dishwasher rubber strip brackets.
[0044] Example 1
[0045] Reference Figures 1 to 10 This embodiment discloses a roller forming line for a dishwasher adhesive strip support, including a cutting assembly 3, a bending assembly 4, a frame 1 for mounting the cutting assembly 3 and the bending assembly 4, and a feed roller belt 2 located at the front end of the cutting assembly 3 for conveying the adhesive strip support 11. A mold seat 6 is correspondingly provided below the bending assembly 4, acting on the bottom of the strip-shaped material 1101. The mold seat 6 has arc-shaped sides. The bending assembly 4 includes a lifting structure and a second U-shaped seat 405. A seventh cylinder 403 is provided on the second U-shaped seat 405, and a first U-shaped... The first U-shaped seat 406 is equipped with a follower cylinder 407 on the outside of the first U-shaped seat 406. The bending wheel 10 is mounted on the third U-shaped seat 408. The arm of the follower cylinder 407 passes through the inside of the first U-shaped seat 406 and is connected to the third U-shaped seat 408. The opening direction of the third U-shaped seat 408 is the same as that of the first U-shaped seat 406, and a slide rail is provided between them. The follower cylinder 407 enables the bending wheel 10 to perform follower bending operations along the arc direction of the end of the mold seat 6.
[0046] The cutting assembly 3 is a cutter 303 driven by a hydraulic cylinder 302. The cutter 303 cuts strip-shaped material 1101 from the rubber strip bracket 11 to a fixed length. In this structure, the cutting assembly 3 also includes a second cylinder 304 and a first base 301 for mounting the hydraulic cylinder 302.

[0047] The bending assembly 4 also includes a third seat 401 located at the top of the frame 1. A sixth cylinder 402 is vertically mounted on the third seat 401, and the arm of the sixth cylinder 402 is connected to the second U-shaped seat 405.

[0048] Example 2
[0049] Reference Figures 4 to 9 Based on the above embodiments, this embodiment also discloses a roller forming line for dishwasher adhesive strip brackets. The mold base 6 has a first support component 5 and a second support component 8 at both ends for downward obstacle avoidance during bending. The two components have the same structure but face opposite directions. Taking the first support component 5 as an example, it includes a second base 502 and a support plate 503 hinged to the second base 502, with a third cylinder 501 connected between them.
