Description

Technical Field

[0001] The present invention belongs to the technical field of polishing machines, and particularly relates to a pan polishing mechanism. Background Art

[0002] After the stamping forming or coating of pans, surface polishing treatment is required. Currently, the polishing of pans in the industry is mainly manual work, which has the disadvantages of high labor intensity, difficult to guarantee product quality, high cost, and poor workshop working environment.

[0003] Then, an automatic polishing machine appears on the market, which realizes the automatic polishing of pans and effectively improves the polishing efficiency of pans. However, when the polishing mechanism on the current automatic polishing machine polishes the arc transition surface of the pan, the polishing abrasive belt cannot closely adhere to the surface of the pan, which is likely to cause uneven polishing. Moreover, the polishing abrasive belt is prone to problems such as deviation and relaxation during the polishing process, thus making it difficult to meet the usage requirements of people. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides a pan polishing mechanism with uniform polishing.

[0005] The technical solution adopted by the present invention to solve the above technical problems is as follows:

[0006] A pan polishing mechanism includes a fixed frame. A longitudinal sliding seat is slidably installed on the fixed frame through a guide rail. A slider is slidably installed on the longitudinal sliding seat through a slide rail. A polishing head is fixedly connected to the slider. A transverse floating device is arranged between the fixed frame and the longitudinal sliding seat. A longitudinal floating device is arranged between the longitudinal sliding seat and the slider. A freely rotatable pressure wheel is connected to the top end of the polishing head. When installing the abrasive belt, it enters from the upper end of the polishing head, bypasses the pressure wheel, and extends from the other direction at the upper end of the polishing head.

[0007] According to some embodiments of the present invention, the transverse floating device and the longitudinal floating device are elastic compression springs or floating cylinders or movable pistons.

[0008] According to some embodiments of the present invention, two sets of the transverse floating device and the longitudinal floating device are respectively provided.

[0009] According to some embodiments of the present invention, a longitudinally arranged positioning cylinder is provided on the fixed frame, and the telescopic rod on the positioning cylinder presses against the polishing head.

[0010] According to some embodiments of the present invention, a sand belt clamping cylinder is arranged inside the polishing head. The movable rod on the sand belt clamping cylinder is connected to a clamping head. Upper and lower rollers that cooperate with the clamping head are arranged inside the polishing head.

[0011] According to some embodiments of the present invention, there are two upper and lower rollers respectively, located on the left and right sides.

[0012] According to some embodiments of the present invention, the clamping head is trapezoidal.

[0013] According to some embodiments of the present invention, the pressure wheel is made of an elastic material.

[0014] According to some embodiments of the present invention, a buffer block is provided between the fixing bracket and the longitudinal sliding seat.

[0015] According to some embodiments of the present invention, a buffer block is provided between the longitudinal sliding seat and the slider.

[0016] The present invention has at least the following beneficial effects: By providing a longitudinal floating device and a transverse floating device, the pressure wheel of the polishing head makes the sand belt in flexible contact with the inner surface of the cookware. Even when polishing the arc transition surface of the cookware, the sand belt can closely adhere to the surface of the cookware, avoiding rigid contact with the multi-layer bottom cookware and causing problems such as extrusion deformation or uneven polishing of the cookware. Uniform polishing effects can be produced on both flat and curved surfaces, further improving the polishing efficiency of the cookware.

[0017] Additional aspects and advantages of the present invention will be given in part in the following description, become apparent in part from the following description, or be learned through the practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following details the embodiments of the present invention. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0023] In the description of the present invention, it should be understood that when it comes to orientation descriptions, such as up, down, etc., the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0024] In the description of the present invention, "a plurality of" refers to more than two. If there is a description of "first" and "second", it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features or implicitly specifying the sequence relationship of the indicated technical features.

[0025] In the description of the present invention, unless otherwise clearly defined, terms such as "set", "installed", "connected", etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0026] Refer to Figure 1 、 Figure 2 , a pot polishing mechanism, which includes a fixed frame 1. A longitudinal sliding seat 2 is slidably installed on the fixed frame 1 through a guide rail 11. A slider 3 is slidably installed on the longitudinal sliding seat 2 through a slide rail 21. A polishing head 4 is fixedly connected to the slider 3. A transverse floating device 5 is provided between the fixed frame 1 and the longitudinal sliding seat 2. A longitudinal floating device 6 is provided between the longitudinal sliding seat 2 and the slider 3. A freely rotatable pressure wheel 41 is connected to the top end of the polishing head 4. When the sand belt is installed, it enters from the upper end of the polishing head 4, bypasses the pressure wheel 41, and extends from the other direction at the upper end of the polishing head 4. The pressure wheel 41 is made of an elastic material, so that during the working process, the sand belt fits more appropriately with the pressure wheel 41.

[0027] The transverse floating device 5 and the longitudinal floating device 6 adopted by this mechanism are elastic compression springs or floating cylinders or movable pistons. In order to ensure that the floating device does not suffer from fatigue failure, two sets of the transverse floating device 5 and the longitudinal floating device 6 are provided respectively.

[0028] Refer to Figure 2 , a positioning cylinder 7 is longitudinally provided on the fixed frame 1. The telescopic rod 71 on the positioning cylinder 7 presses against the polishing head 4. When it is necessary to change the sand belt, start the positioning cylinder 7 to press the telescopic rod 71 against the polishing head 4, so that the longitudinal floating device 6 cannot function, thus facilitating the replacement of the sand belt. After the replacement is completed, retract the telescopic rod 71. At this time, the longitudinal floating device 6 resumes its floating function.

[0029] Refer to Figure 3, a sand belt clamping cylinder 42 is arranged inside the polishing head 4. A movable rod 421 on the sand belt clamping cylinder 42 is connected to a clamping head 423. Upper and lower rollers 43 and 44 that cooperate with the clamping head 423 are arranged inside the polishing head 4. There are two upper and lower rollers 43 and 44 respectively, located on the left and right sides. The clamping head 423 is trapezoidal. During operation, the clamping head 423 moves upward driven by the sand belt clamping cylinder 42, so as to clamp the sand belt between the clamping head 423 and the upper roller 43. The use of the sand belt clamping cylinder 42 ensures that the sand belt does not deviate or slack during the sanding process.

[0030] In order to prevent rigid collisions from occurring during the movement of the longitudinal slide 2 and the slider 3, a buffer block 8 is arranged between the fixed frame 1 and the longitudinal slide 2; a buffer block 8 is arranged between the longitudinal slide 2 and the slider 3.

[0031] By arranging a longitudinal floating device 6 and a transverse floating device 5, the pressing wheel 41 of the polishing head 4 makes the sand belt in flexible contact with the inner surface of the cookware. Even when polishing to the arc transition surface of the cookware, the sand belt can closely adhere to the surface of the cookware, avoiding rigid contact with the multi-bottom cookware and causing problems such as extrusion deformation or uneven polishing of the cookware. Uniform polishing effects can be produced on both flat and curved surfaces, further improving the polishing efficiency of the cookware.

[0032] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention through logical analysis, reasoning, or limited experiments based on the concept of the present invention on the basis of the prior art should be within the protection scope determined by the claims.
