Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically an electric contour grinding machine. Background Technology

[0002] Bamboo bowls are bamboo containers made by cutting and assembling bamboo slabs and then refining them. With the continuous development and improvement of bamboo products, the use of bamboo bowls has increased, resulting in various types such as bamboo rice bowls, bamboo noodle bowls, and bamboo salad bowls, which are very popular. In the production of bamboo bowls, the cut and assembled bamboo bowl blanks need to be placed on a polishing machine for polishing to make the inner and outer surfaces smooth and aesthetically pleasing. Currently, the polishing of bamboo bowls is generally done manually by holding sandpaper and rotating the bamboo bowl blank on the polishing machine, which is inefficient. Therefore, further improvements are needed to increase production efficiency.

[0003] For example, an automatic bamboo bowl shaping and polishing device (publication number: CN205572137U) includes an automatic polishing power unit, a shaping and polishing device, and a bamboo bowl fixing device. The automatic polishing power unit is equipped with a power transmission mechanism driven by a variable frequency motor. The power transmission mechanism has a downwardly inclined rotating shaft with a mounting flange fixedly connected to the shaping and polishing device. The shaping and polishing device has a connecting flange that can float and rotate around the rotating shaft. The connecting flange is connected to a polishing brush head that can be easily replaced. The bamboo bowl fixing device has a movable clamp that can clamp the bamboo bowl blank. This utility model, by setting a shaping and polishing device that can float and rotate around the bamboo bowl blank, allows the polishing brush head in the shaping and polishing device to be set and replaced according to the bamboo bowl blank. The polishing brush head has strong polishing force and is very suitable for rough polishing, which can greatly improve polishing production efficiency.

[0004] However, the device still has the following drawbacks: The aforementioned device only secures the bamboo bowl using a bamboo bowl fixing device and a movable clamp, resulting in poor stability. In actual use, when the polishing brush head polishes the bamboo bowl, the bamboo bowl is continuously subjected to force from the polishing brush head, which can easily cause the bamboo bowl to bounce upwards and separate from the bamboo bowl fixing device, leading to a poor user experience. Utility Model Content

[0005] The purpose of this utility model is to provide an electric contour sander that limits the wooden bowl by setting a limiting component on the annular plate, thereby reducing the probability of the wooden bowl shaking when subjected to external force, and further reducing the probability of the wooden bowl shaking when the sanding brush head is sanding.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an electric contour polishing machine, comprising an automatic polishing power unit and a contour polishing device mounted on the automatic polishing power unit, wherein a polishing brush head is connected to the end of the contour polishing device; an automatic rotating disc, wherein the automatic rotating disc is mounted on the automatic polishing power unit; further comprising a mounting plate, wherein the mounting plate is mounted on the automatic rotating disc, and a triangular block fixed to the upper surface of the mounting plate, wherein an annular plate is mounted on the upper surface of the mounting plate, and the sidewall of the triangular block abuts against the inner wall of the annular plate; further comprising a limiting component, wherein the limiting component is mounted on the annular plate for improving the stability of the bamboo bowl.

[0007] Preferably, the limiting component includes a fixing rod fixedly disposed on the side wall of the annular plate, and a suction cup fixed to the fixing rod; it also includes an adjustment device disposed on the annular plate for adjusting the working state of the suction cup.

[0008] Preferably, the annular plate has an arc-shaped groove on its side wall, and the adjusting device includes a connecting rod rotatably disposed in the arc-shaped groove and a mounting block fixed to the end of the connecting rod.

[0009] Preferably, the annular plate has an annular groove on its side wall that communicates with the arc-shaped groove, and an annular piece is rotatably disposed in the annular groove, the inner wall of the annular piece being fixed to the connecting rod.

[0010] Preferably, the axis of the fixing rod is parallel to the upper surface of the triangular block.

[0011] Preferably, an arc-shaped piece is fixed on the side wall of the connecting rod, and the end of the arc-shaped piece away from the connecting rod is slidably connected to the inner wall of the arc-shaped groove.

[0012] Preferably, the sidewall of the annular piece is provided with a frosted layer to reduce the difficulty for workers to rotate the annular piece.

[0013] Preferably, the inner wall of the annular plate is provided with a rubber sheet to improve the stability of the wooden bowl.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: When sanding the inner wall of a wooden bowl, the worker connects the upper surface of the annular plate to the mounting plate and places the triangular block inside the annular plate. This allows the triangular block to press firmly against the inner wall of the annular plate, forming a unified structure. The worker then places the wooden bowl inside the annular plate, where the bowl is initially stabilized by the combined action of the triangular block and the annular plate. Further, the worker presses down on the inner wall of the bowl, causing it to move diagonally downwards under the combined force of the triangular block and external pressure. This continuously compresses the suction cup, stabilizing the bowl and reducing the likelihood of it wobbling during sanding. Finally, the worker simply activates the contour sanding device, rotating the sanding brush head to sand the inner wall of the bowl, thus simplifying the operation. Attached Figure Description

[0017] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0018] Example 1 Please see Figures 1 to 4The present invention preferably provides the following technical solution: an electric contour polishing machine, comprising an automatic polishing power unit 1 and a contour polishing device 11 mounted on the automatic polishing power unit 1, wherein a polishing brush head 2 is connected to the end of the contour polishing device 11; an automatic rotating disk 21, wherein the automatic rotating disk 21 is mounted on the automatic polishing power unit 1; a mounting plate 3, wherein the mounting plate 3 is mounted on the automatic rotating disk 21, and a triangular block 31 fixed to the upper surface of the mounting plate 3, wherein an annular plate 4 is mounted on the upper surface of the mounting plate 3, and the side wall of the triangular block 31 abuts against the inner wall of the annular plate 4; and a limiting component 5, wherein the limiting component 5 is mounted on the annular plate 4 for improving the stability of the bamboo bowl.

[0019] In this embodiment, the worker needs to place the wooden bowl into the annular plate 4, which initially stabilizes the bowl under the combined action of the triangular block 31 and the annular plate 4. Further, the worker needs to press down on the inner wall of the bowl, causing it to move diagonally downwards under the combined action of the triangular block 31 and external force. This continuously compresses the suction cup 52, thus stabilizing the bowl under the suction cup 52 and reducing the probability of the bowl shaking during polishing. Specifically, the staff only needs to turn on the contour polishing device 11 to make the polishing brush head 2 rotate, and then make the polishing brush head 2 polish the inner wall of the wooden bowl, thereby reducing the difficulty of operation for the staff. It is worth noting that when the staff needs to polish the inner wall of the wooden bowl, the staff needs to connect the upper surface of the ring plate 4 and the mounting plate 3, and put the triangular block 31 into the ring plate 4, so that the triangular block 31 can press against the inner wall of the ring plate 4, thereby making the triangular block 31 and the ring plate 4 form a whole.

[0020] Furthermore, the limiting component 5 includes a fixing rod 51 fixedly disposed on the side wall of the annular plate 4, and a suction cup 52 fixed to the fixing rod 51; it also includes an adjusting device 6 disposed on the annular plate 4 for adjusting the working state of the suction cup 52.

[0021] Combination Figure 2 As shown, when the worker needs to polish the inner wall of the wooden bowl, the worker needs to place the wooden bowl into the ring plate 4 and press down on the inner wall of the wooden bowl. This will cause the suction cup 52 to contract and adhere to the side wall of the wooden bowl under the action of the wooden bowl. In this way, the wooden bowl will remain stable under the combined action of the suction cup 52, the ring plate 4 and the triangular block 31, thereby reducing the probability of the wooden bowl shaking when the worker polishes it.

[0022] Furthermore, an arc-shaped groove 53 is provided on the side wall of the annular plate 4, and the adjusting device 6 includes a connecting rod 61 rotatably disposed in the arc-shaped groove 53, and a mounting block 62 fixed to the end of the connecting rod 61.

[0023] Furthermore, an annular groove 7, which communicates with the arc-shaped groove 53, is provided on the side wall of the annular plate 4. An annular piece 71 is rotatably disposed in the annular groove 7, and the inner wall of the annular piece 71 is fixed to the connecting rod 61.

[0024] like Figure 3 As shown, after the inner wall of the wooden bowl is polished, the worker needs to rotate the annular plate 71, which will cause the connecting rod 61 to rotate with the annular plate 71. This will cause the mounting block 62 to move closer to the suction cup 52 and press against the edge of the suction cup 52, thereby deforming the edge of the suction cup 52 and separating the suction cup 52 from the wooden bowl. At this time, the worker only needs to pull the wooden bowl upward to separate the wooden bowl from the annular plate 4.

[0025] Furthermore, the axis of the fixing rod 51 is parallel to the upper surface of the triangular block 31.

[0026] This increases the probability that the side wall of the wooden bowl will press against the suction cup 52 when the staff presses it down, thereby improving the adsorption effect of the suction cup 52.

[0027] Furthermore, an arc-shaped piece 8 is fixed on the side wall of the connecting rod 61, and the end of the arc-shaped piece 8 away from the connecting rod 61 is slidably connected to the inner wall of the arc-shaped groove 53.

[0028] When the polishing brush head 2 polishes the inner wall of the wooden bowl, a large amount of debris is easily generated on the inner wall of the wooden bowl. At this time, since the connecting rod 61 is away from the side wall of the arc-shaped piece 8 and presses against the inner wall of the arc-shaped groove 53, the arc-shaped piece 8 completely covers the arc-shaped groove 53. The arc-shaped piece 8 reduces the probability of impurities entering the arc-shaped groove 53, thereby reducing the probability of the connecting rod 61 getting stuck.

[0029] Furthermore, the sidewall of the annular plate 71 is provided with a frosted layer 81 to reduce the difficulty for workers to rotate the annular plate 71.

[0030] This reduces the probability of slippage when the staff rotates the annular plate 71, thereby improving the staff's user experience.

[0031] Furthermore, the inner wall of the annular plate 4 is provided with a rubber sheet 9 for improving the stability of the wooden bowl.

[0032] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "fixation" and other terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit ​​method, or by using a bolt connection, etc.

[0033] The above description of the specific embodiments of this utility model is only used to further illustrate this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-essential improvements and adjustments made to this utility model by technical engineers based on the above description of the utility model shall fall within the scope of protection of this utility model.
