Description

Technical Field

[0001] The present invention relates to the field of container inner wall polishing, and more specifically, to a container inner wall polishing device. Background Art

[0002] Containers are usually welded by multiple steel plates. During the production process of these steel plates, in order to increase the thickness and stiffness of the inner wall of the container formed by subsequent splicing, these steel plates are usually processed into strip-shaped or rib-shaped reinforcing ribs and other structures to improve the strength and compressive resistance of the overall structure of the container. At the same time, in order to improve the flatness and smoothness of the inner wall of the container formed after splicing and reduce the frictional damage during subsequent cargo loading and unloading, a polishing device is usually used to polish the inner wall;

[0003] However, during the process of manually using a polishing device to polish the inner wall of a container, affected by personal factors and factors such as light shielding on the inner wall of the container, it is easy to reduce the polishing effect and polishing uniformity of the arc-shaped edges and corners of the irregular parts (i.e., parts of structures such as reinforcing ribs) on the inner wall of the container, that is, it is easy to reduce the overall polishing effect of the device on the container;

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0049] Please refer to Figures 1 to 14 , a polishing device for the inner wall of a container, including a polishing main body 1, a protective cover 2 fixedly installed on the polishing main body 1, a driving component 3 arranged on the protective cover 2, and an adjusting component 5 arranged inside the protective cover 2.

[0050] As Figure 1 - Figure 7 shown, the driving component 3 includes a rotating shaft 36 rotatably installed on the inner top wall of the protective cover 2, a polishing wheel 4 installed at the lower end of the rotating shaft 36, and a driving mechanism jointly installed between the rotating shaft 36 and the protective cover 2;

[0051] The driving mechanism includes an air collecting cylinder 31 fixedly installed at the upper end of the protective cover 2, a servo motor 32 fixedly installed on the inner top wall of the air collecting cylinder 31, a rotating shaft 33 fixedly installed at the driving end of the servo motor 32, and the rotating shaft 33 penetrates and is rotatably installed on the protective cover 2. A rotating gear one 34 is fixedly installed on the rotating shaft 33, and a rotating gear two 37 meshing with the rotating gear one 34 is fixedly installed on the rotating shaft 36. A wind collecting component is installed on the rotating shaft 33.

[0052] Specifically, a detachable connection method such as a thread can be adopted between the rotating shaft 36 and the polishing wheel 4, aiming to facilitate the replacement of the polishing wheel 4 by the staff after using the device to polish the inner wall of the container for a long time, so as to ensure the polishing effect of the polishing wheel 4 on the inner wall of the container.

[0053] At the same time, the polishing wheel 4 is specifically made of elastic materials such as rubber and felt, aiming to facilitate the device to adapt and change the shape of the polishing wheel 4 according to the surface shape of the inner wall of the container through the adjusting component 5 when polishing the inner wall of the container.

[0054] The inner wall of the existing container usually has structures such as reinforcing ribs. These structures are usually strip-shaped or rib-shaped (as can be seen from Figure 1 and Figure 1 shows a partial structural schematic diagram of the inner wall of the container). Among them, the reinforcing ribs can increase the thickness and stiffness of the inner wall of the container, disperse external forces, thereby improving the strength and compressive resistance of the overall structure of the container and helping to extend the service life of the container.

[0055] Meanwhile, when the device is needed to polish the inner wall of the container, first, through the adjusting component 5, the polishing wheel 4 is closely attached to the position to be polished on the inner wall of the container. Then, the servo motor 32 is started. The operation of the servo motor 32 can drive the polishing wheel 4 to rotate to polish the inner wall of the container through the cooperation of the rotating shaft 33, the first rotating gear 34, and the second rotating gear 37.

[0056] As Figure 1 - Figure 8 shown, the adjusting component 5 includes a positioning plate 53 fixedly installed on the inner wall of the protective cover 2. A plurality of extrusion rods 54 are penetrated and slidably installed on the positioning plate 53. Two electric telescopic rods 51 are fixedly installed on the protective cover 2. The lower ends of the two electric telescopic rods 51 are jointly fixedly installed with a pressing disc 52, and the pressing disc 52 is hermetically and slidably installed on the inner wall of the protective cover 2. A pressing mechanism is jointly installed between the extrusion rod 54 and the pressing disc 52. A speed regulating component 7 is arranged on the outer surfaces of the two electric telescopic rods 51.

[0057] The pressing mechanism includes a plurality of square openings 55 opened on the pressing disc 52. Round rods 56 are rotatably installed on the square openings 55. Torsion springs 57 are fixedly installed between the round rods 56 and the corresponding square openings 55. Pressing plates 58 matched with the corresponding extrusion rods 54 are fixedly installed on the round rods 56. Sealing rings 511 are fixedly installed on the square openings 55, and the extrusion rods 54 are hermetically penetrated and slidably installed on the corresponding sealing rings 511. A limiting component is jointly installed between the square openings 55 and the extrusion rods 54.

[0058] The limiting component includes a plurality of sliding grooves 510 opened on the pressing disc 52, and the sliding grooves 510 are all communicated with the corresponding square openings 55. Sliders 59 are fixedly installed on the extrusion rods 54, and the sliders 59 are all slidably installed in the corresponding sliding grooves 510.

[0059] As Figure 7 can be seen, the inner wall of the container usually has structures such as strip-shaped reinforcing ribs. Most of the polishing wheels 4 are flat-bottomed. Therefore, when the staff uses the device to polish the inner wall of the container, it is difficult for the lower end of the polishing wheel 4 to completely fit the two arc-shaped edges on both sides of the convex part of the inner wall of the container, which easily leads to the inability to fully polish these parts, resulting in polishing dead corners, and then affecting the overall polishing effect of the inner wall of the container. At the same time, when the device is manually moved to polish the inner wall of the container, due to the influence of human factors, it is difficult to maintain the same polishing pressure on the arc-shaped edges and flat parts of its inner wall. Therefore, it is easy to reduce the uniformity of the overall polishing of the inner wall of the container by the device.

[0060] When the device is needed to polish the inner wall of the container, first, manually align and attach the polishing wheel 4 to the strip-shaped convex part on the inner wall of the container through the polishing main body 1 (such asFigure 7 the state shown), and then start the two electric telescopic rods 51. At this time, the operation of the two electric telescopic rods 51 will drive the pressing plate 52 to move downward (as shown in the Figure 7 indicated direction). During the downward movement of the pressing plate 52, the downward pressure generated by the multiple pressing plates 58 on it on the corresponding extrusion rods 54 will drive the multiple extrusion rods 54 to move downward together;

[0061] At this time, when the reaction force generated by the polishing wheel 4 on the corresponding multiple extrusion rods 54 at the flat part of the convex part of the inner wall of the container is greater than the elastic force of the corresponding multiple torsion springs 57, the multiple extrusion rods 54 at the middle part of the polishing wheel 4 will press upward against the corresponding pressing plates 58, causing them to rotate upward (as shown in the Figure 8 indicated direction), and the multiple extrusion rods 54 on both sides of the polishing wheel 4 (i.e., above the arc-shaped edges on both sides of the convex part of the inner wall of the container) will continue to move downward, cooperating to press both sides of the polishing wheel 4 until both sides of the polishing wheel 4 are in close contact with the arc-shaped edges on both sides of the convex part of the inner wall of the container. This can help improve the polishing effect and polishing uniformity of the flat part and arc-shaped edges of the convex part of the inner wall of the container during subsequent manual use of the equipment, and help improve the overall polishing effect of the equipment on the inner wall of the container.

[0062] At the same time, when the equipment polishes the concave part of the inner wall of the container and the polishing wheel 4 gradually approaches the concave part of the inner wall of the container, through the above operations, the effect of automatically adjusting the shape of the polishing wheel 4 according to the shape of the area to be polished can be achieved, which helps improve the overall polishing effect and polishing uniformity of the equipment on the inner wall of the container.

[0063] At the same time, it is set that when the polishing wheel 4 is completely attached to the area to be polished on the inner wall of the container, the upper ends of the multiple extrusion rods 54 are all above the pressing plate 52 at this time, that is, the resistance exerted by the multiple extrusion rods 54 on the corresponding pressing plates 58 at this time makes the multiple pressing plates 58 all in a vertical state, and at this time, the multiple sliders 59 all move out of the corresponding chutes 510.

[0064] When it is necessary to polish other irregular areas on the inner wall of the container or after the polishing of the inner wall of the container is completed, at this time, by starting the two electric telescopic rods 51 again, the pressing plate 52 can be driven to move upward and reset. When the sliders 59 above the multiple extrusion rods 54 contact the lower ends of the corresponding chutes 510, the resistance exerted by the multiple extrusion rods 54 on the corresponding pressing plates 58 disappears at this time. At this time, through the elastic force of the multiple torsion springs 57, the multiple round rods 56 can drive the corresponding pressing plates 58 to rotate clockwise and reset (as shown in the Figure 8In the shown direction), at this time, through the cooperation of multiple pressing plates 58 and torsion springs 57, an upward resistance is applied to the corresponding extrusion rods 54, and the pressing disc 52 applies an upward thrust to the corresponding extrusion rods 54 through the cooperation of multiple sliding grooves 510 and sliders 59, which can push the multiple extrusion rods 54 to move upward and reset until the lower end of the polishing wheel 4 returns to its original shape, so as to facilitate the subsequent adjustment of the shape of the polishing wheel 4 according to the shape of the area to be polished on the inner wall of the container.

[0065] At the same time, when the extrusion rods 54 are forced to move upward or downward (such as Figure 8 in the shown direction), through the cooperation of the positioning plate 53 and the corresponding sealing rings 511, the movement of the multiple extrusion rods 54 can be limited, which can help improve the effect of the multiple extrusion rods 54 being forced to move to adjust the shape of the polishing wheel 4.

[0066] Such as Figure 4 - Figure 6 、 Figure 9 - Figure 11 As shown in the figure, a cleaning component 6 is provided on the protective cover 2. The cleaning component 6 includes a support plate 65 fixedly installed on the side wall of the protective cover 2. There are two support plates 65, and threaded openings are provided on both support plates 65, and threaded rods 66 are threadedly installed on the threaded openings;

[0067] At the lower ends of the two threaded rods 66, a cover body 67 is rotatably installed. An air delivery component is installed between the two cover bodies 67 and the air collecting cylinder 31. On the inner walls of the two cover bodies 67, a rotating rod 68 is rotatably installed. On the two rotating rods 68, a roller 611 is fixedly installed. A resilient component is installed between the two rotating rods 68 and the two cover bodies 67. A force transmission component is installed between the two rotating rods 68 and the extrusion plate 71.

[0068] The air gathering component includes a fan 35 fixedly installed on the rotating shaft 33. An air inlet is provided on the air collecting cylinder 31. There are two air inlets, and filter meshes (drawn but not marked in the figure, visible from Figure 10 the figure) are fixedly installed on both air inlets.

[0069] The air delivery component includes a one-way air delivery pipe 61 fixedly connected to the air collecting cylinder 31, and one end of the one-way air delivery pipe 61 penetrates and is fixedly installed on the corresponding support plate 65. A one-way air delivery pipe 62 is fixedly connected to the air collecting cylinder 31. A delivery air pipe 620 is fixedly connected to the one-way air delivery pipe 62, and one end of the delivery air pipe 620 penetrates and is fixedly installed on the corresponding support plate 65. Exhaust air pipes 63 are fixedly connected to both the one-way air delivery pipe 61 and the delivery air pipe 620. Exhaust air pipes 64 are fixedly connected to both the one-way air delivery pipe 61 and the delivery air pipe 620;

[0070] Two rotating rods 68 are both rotatably installed with air collecting cylinders 69, and the two air collecting cylinders 69 are both hermetically penetrated and rotatably installed on the corresponding drums 611. Branch pipes 610 are fixedly communicated between the two first exhaust pipes 63 and the corresponding air collecting cylinders 69, and the two branch pipes 610 are both hermetically penetrated and fixedly installed on the corresponding covers 67.

[0071] When a person uses the device to polish the inner wall of the container from top to bottom or from bottom to top, the impurities adhering to the inner wall of the container are likely to reduce the polishing effect of the device on its inner wall. At the same time, impurities such as splashing debris generated during the polishing process are likely to hit the inner wall of the container again, causing new minute scratches or pits, and also likely to reduce the polishing effect of the device on the inner wall of the container.

[0072] When the servo motor 32 operates, through the cooperation of the rotating shaft 33 and the rotating shaft 36, the polishing wheel 4 is driven to rotate to polish the inner wall of the container. At this time, through the rotation of the rotating shaft 33, the fan 35 can be driven to rotate to suck the external gas into the air collecting cylinder 31 through the two air inlets. The gas entering the air collecting cylinder 31 will finally flow into the two first exhaust pipes 63 and the two second exhaust pipes 64 along the cooperation of the one-way air conveying pipe 61, the one-way air conveying pipe 62 and the air supply pipe 620, and will finally be ejected from the two first exhaust pipes 63 and the two second exhaust pipes 64;

[0073] And part of the gas entering the two first exhaust pipes 63 will enter the two drums 611 along the cooperation of the corresponding branch pipes 610 and the air collecting cylinders 69, and will finally be ejected from the multiple round holes opened at the lower ends of the two drums 611 (as can be seen from Figure 11 multiple round holes are opened on both of the two drums 611), so as to realize the effect of blowing and cleaning the impurities at the front and rear positions of the polishing path of the device (that is, the areas on the inner wall of the container to be polished and the polished area) through the cooperation of the two first exhaust pipes 63 and the corresponding second exhaust pipes 64 and the drums 611 during the process of manually moving the device to polish the inner wall of the container (such as the Figure 9 direction shown). This can help improve the polishing effect of the device on the inner wall of the container, reduce the impurities on the area to be polished on the inner wall of the container, and the situation where impurities such as debris generated during polishing affect the polishing effect of the inner wall of the container.

[0074] At the same time, combined with Figure 9 and Figure 10It can be seen that two fixing blocks are fixedly installed at the upper ends of the two cover bodies 67, and the two first exhaust pipes 63 and the two second exhaust pipes 64 penetrate and are fixedly installed on the corresponding fixing blocks. Fixing the positions of the corresponding first exhaust pipe 63 and the second exhaust pipe 64 through multiple fixing blocks can help improve the stability of the cooperation between the first exhaust pipe 63 and the second exhaust pipe 64 in jetting and cleaning the inner wall of the container. Moreover, a convex block is also provided at the upper end of the protective cover 2, and this convex block can help improve the stability of the one-way second air conveying pipe 62 in conveying air to the air supply pipe 620.

[0075] As Figure 9 - Figure 13 shown, the speed regulating assembly 7 includes a pressing plate 71 that is hermetically and slidably installed between the protective cover 2 and the rotating shaft 36, and the pressing plate 71 hermetically penetrates and is slidably installed between the two electric telescopic rods 51. An extrusion component is jointly installed between the pressing plate 71 and the rotating shaft 36.

[0076] The elastic return component includes brackets 612 respectively fixedly installed on the two rotating rods 68. Arc-shaped grooves 613 are formed on both of the two cover bodies 67. Moving blocks 614 are fixedly installed at one ends of the two brackets 612, and the two moving blocks 614 are both slidably installed in the corresponding arc-shaped grooves 613. Compression springs 615 are fixedly installed on both of the two arc-shaped grooves 613, and the two compression springs 615 are fixedly connected to the corresponding moving blocks 614.

[0077] The force transmission component includes parallel shaft gears 616 respectively fixedly installed on the two rotating rods 68. Limit plates (drawn in the figure but not labeled, which can be seen from Figure 12 it) are fixedly installed on both of the two support plates 65. Connecting rods 617 penetrate and are slidably installed on both of the two limit plates. Rack bars 618 meshing with the corresponding parallel shaft gears 616 are fixedly installed at the lower ends of the two connecting rods 617;

[0078] Upper ends of the two connecting rods 617 are fixedly installed with telescopic rods 619, and lower ends of the two telescopic rods 619 are fixedly connected to the pressing plate 71. The two telescopic rods 619 penetrate and are slidably installed on the protective cover 2. Limit displacement plates 72 are fixedly installed on the inner wall of the protective cover 2, and there are two limit displacement plates 72.

[0079] As Figure 13 shown, when in the initial state, the lower end of the polishing wheel 4 is flush with the lower ends of the two rollers 611.

[0080] When the polishing wheel 4 is in close contact with the part of the inner wall of the container to be polished and the two rollers 611 are in contact with the inner wall of the container, it is necessary to first adjust the heights of the two rollers 611 according to the movement of the device held manually by the person, that is, the polishing direction. If when the person holds the polishing main body 1 and moves downwards to polish the inner wall of the container (such as Figure 9In the direction shown, it is necessary to first rotate the upper threaded rod 66 so that the upper cover 67 drives the corresponding roller 611 to move away from the inner wall of the container. In this way, the roughness of the inner wall of the container can be automatically detected by the lower roller 611 in the subsequent process, and when adjusting the polishing pressure and polishing speed of the polishing wheel 4 according to the detection results, the situation where the upper roller 611 affects the detection results can be avoided. On the contrary, when the polishing main body 1 is manually held and moved upward to polish the inner wall of the container, at this time, it is necessary to manually rotate the lower threaded rod 66 so that the lower roller 611 is separated from the inner wall of the container.

[0081] Due to factors such as raw materials and processing technology, the roughness of the inner walls of different containers is likely to vary. When the roller 611 moves on the surface of the inner wall of the container with a higher roughness, if the frictional resistance generated by the movement of the inner wall of the container on the roller 611 is greater than the self-elastic deformation force of the corresponding compression spring 615, at this time, the roller 611 will drive the corresponding rotating rod 68 to rotate. On the contrary, if the roughness of the inner wall of the container is small, at this time, the frictional resistance generated by the inner wall of the container on the moving roller 611 is difficult to overcome the self-elastic force of the corresponding compression spring 615, that is, it is difficult to make the roller 611 rotate and displace;

[0082] If when the polishing wheel 4 moves to the right (such as Figure 13 in the direction shown), and the roughness of the inner wall of the container is high, at this time, the frictional resistance generated by the inner wall of the container on the right roller 611 will cause the right roller 611 to rotate clockwise (such as Figure 13 in the direction shown) with the corresponding rotating rod 68 as the axis. At this time, through the cooperation of the corresponding rotating rod 68 with the corresponding parallel shaft gear 616, rack rod one 618, and connecting rod 617, the corresponding telescopic rod 619 can be driven to press the pressing plate 71 downward (such as Figure 13 in the direction shown).

[0083] When set in the initial state, a large amount of gas is stored between the pressing plate 71 and the pressing disk 52 (at the same time, through the cooperation of the sealing ring 511 and the corresponding pressing rod 54, the gas above the pressing disk 52 can be sealed). When the roughness of the inner wall of the container is high, at this time, through the cooperation of the roller 611 in the polishing direction of the equipment with the corresponding connecting rod 617 and telescopic rod 619, the pressing plate 71 can be driven to move downward, compressing the gas between the pressing plate 71 and the pressing disk 52. In this way, the pressure of this part of the gas can be increased. At the same time, through the fluidity of the gas, the gas with increased pressure in this part can evenly generate a downward pressure on the multiple pressing rods 54, so that the multiple pressing rods 54 cooperate to press the polishing wheel 4 downward. In this way, the polishing pressure of the polishing wheel 4 on the area to be polished on the inner wall of the container can be increased, which helps to improve the sufficiency of the equipment for polishing the inner wall of the container with a higher roughness and helps to improve the polishing effect of the equipment on the inner walls of containers with different roughnesses.

[0084] When the inner wall roughness of the container is different, if the polishing pressure of the equipment is not adjusted in time according to the roughness of the inner wall of the container, it is easy to have a poor polishing effect in the area with higher roughness or over-polishing in the area with lower roughness. Therefore, adjusting the polishing pressure of the polishing wheel 4 in time according to the roughness of the inner wall of the container can help to further improve the polishing effect of the equipment on the inner wall of the container.

[0085] At the same time, the higher the roughness of the inner wall of the container, the greater the frictional resistance generated on the corresponding roller 611. At this time, the longer the distance that the roller 611 rotates and drives the pressing plate 71 to move downward, that is, the greater the downward pressure generated by the pressing plate 71 on the polishing wheel 4 through the compressed gas and the cooperation of multiple pressing rods 54, and vice versa. In this way, the effect of automatically adjusting the polishing pressure of the polishing wheel 4 according to the roughness of the inner wall of the container can be achieved.

[0086] When the equipment moves to the area with lower roughness, when the frictional resistance generated on the corresponding roller 611 in this area decreases, at this time, under the action of the self-elastic force of the corresponding compression spring 615, the corresponding rotating rod 68 can be driven to drive the roller 611 to gradually rotate and reset. And in this process, through the cooperation of the corresponding parallel shaft gear 616 and the telescopic rod 619, the pressing plate 71 can be driven to move upward and reset (as Figure 13 shown in the direction), that is, gradually reduce the extrusion force of the multiple pressing rods 54 on the polishing wheel 4.

[0087] At the same time, the one-way air supply pipe 61 and the air supply pipe 620 are arranged in the middle of the corresponding support plate 65 and the cover 67, and are specifically made of elastic materials. The purpose is to facilitate the corresponding exhaust pipe 63 and the exhaust pipe 64 to cooperate to compress or stretch the corresponding one-way air supply pipe 61 and the air supply pipe 620 during the process of adjusting the height of the roller 611 as required.

[0088] At the same time, the purpose of setting two limit plates 72 and adding two telescopic rods 619 between the two connecting rods 617 and the pressing plate 71 is that when adjusting the height of the roller 611 on one side of the polishing wheel 4 according to the moving direction of the polishing wheel 4, at this time, an upward driving force is applied to the corresponding rack bar 618 through the corresponding parallel shaft gear 616 (as Figure 13 shown in the direction), which can make the rack bar 618 on this side drive the corresponding connecting rod 617 and the telescopic rod 619 to move upward together. However, due to the movement limit of the pressing plate 71 by the telescopic rod 619 on the other side and the two limit plates 72 at this time, even if the rack bar 618 on this side and the corresponding connecting rod 617 move upward, the corresponding telescopic rod 619 will be stretched. At the same time, when one side roller 611 rotates and presses the pressing plate 71 to move downward through the corresponding telescopic rod 619, at this time, the pressing plate 71 will stretch the telescopic rod 619 on the other side.

[0089] As Figure 13 , Figure 14 shown, the extrusion member includes positioning blocks 73 fixedly installed on the inner top wall of the protective cover 2. There are two positioning blocks 73. Through both of the two positioning blocks 73, lead screws 74 are rotatably installed. Fixedly installed on both of the two lead screws 74 are spur gears 75. Fixedly installed on the extrusion plate 71 are two rack bars 76. And both of the two rack bars 76 are engaged with the corresponding spur gears 75. Threadedly installed on both of the two lead screws 74 are fixing members 77. Fixedly installed on both of the two fixing members 77 are friction pads 78.

[0090] It is set that both of the two friction pads 78 are made of elastic materials, such as polyurethane materials, etc., and when the two friction pads 78 are in the initial state, they are both in contact with the surface of the rotating shaft 36.

[0091] When the surface roughness of the inner wall of the container is relatively high, the roller 611 on the advancing side of the polishing by the driving device is forced to rotate, and when driving the extrusion plate 71 to move downward, at this time, the extrusion plate 71 will drive the two rack bars 76 to move downward together (as in Figure 14 the shown direction), and during the downward movement of the two rack bars 76, through the cooperation with the corresponding spur gears 75 and lead screws 74 (it is set that the thread directions of the two lead screws 74 are opposite), the two fixing members 77 can be driven to drive the corresponding friction pads 78 to approach each other. And during the process of the two friction pads 78 approaching each other, the frictional resistance to the rotating shaft 36 can be gradually increased, so that when the device polishes the inner wall of the container with relatively high roughness, the effect of adaptively reducing the polishing speed of the rotating shaft 36 driving the polishing wheel 4 can be achieved;

[0092] In this way, while increasing the polishing pressure of the polishing wheel 4 by the downward movement of the extrusion plate 71 and improving the polishing effect of the polishing wheel 4 on the area with relatively high roughness of the inner wall of the container, by reducing the polishing speed of the rotating shaft 36 driving the polishing wheel 4, the polishing effect of the polishing wheel 4 on the inner wall of the container can be further improved;

[0093] Since the flatness of the relatively rough area of the inner wall of the container is relatively poor, if a relatively fast polishing speed is adopted at this time, it is easy to reduce the stability of the contact pressure and frictional force between the polishing wheel 4 and the inner wall of the container, and it is easy to cause the situation of "jumping" of the local part of the polishing wheel 4 on its surface, thus generating new scratches and pits. At the same time, at this relatively fast polishing speed, it is easy to increase the frictional force generated between the inner wall of the container and the polishing wheel 4, which is easy to increase the wear of the polishing wheel 4 and reduce the service life of the polishing wheel 4.

[0094] Meanwhile, when the relatively rough area of the inner wall of the container is preliminarily polished by increasing the polishing pressure of the polishing wheel 4 and decreasing the polishing speed of the polishing wheel 4, if further fine polishing treatment is required for this area, first manually hold the polishing body 1 to move the polishing wheel 4 away from the inner wall of the container. At this time, under the automatic elastic force of the corresponding compression spring 615, the corresponding roller 611, the extrusion plate 71 and the two friction pads 78 can be driven to move back to their original positions. Then repeat the above operation to drive the polishing wheel 4 to polish this area again. At this time, since this area has been polished before, the roughness is relatively reduced, that is, the corresponding roller 611 on one side cannot be driven to rotate. Therefore, at this time, through the lower polishing pressure and higher polishing speed of the polishing wheel 4, further fine polishing treatment of the inner wall of the container can be achieved, so as to meet the requirements of different polishing degrees of the inner wall of the container;

[0095] Meanwhile, when the equipment polishes the inner wall of the container with relatively low roughness and the frictional resistance between the inner wall of the container and the roller 611 cannot drive the roller 611 to rotate, at this time, through the lower polishing pressure and higher polishing speed of the polishing wheel 4, fine polishing of the inside of the container by the equipment can be achieved.

[0096] Meanwhile, from Figure 14 it can be seen that the two rack bars two 76 are intermittently engaged with the corresponding spur gears 75, and the tooth blocks on the corresponding spur gears 75 and the rack bars two 76 are relatively small. That is, every time the rack bar two 76 drives the corresponding spur gear 75 to rotate, the corresponding lead screw 74 drives the corresponding fixing member 77 and the friction pad 78 to move a relatively short distance, so as to ensure that the two friction pads 78 gradually increase the resistance to the rotation of the rotating shaft 36 according to the downward movement distance of the extrusion plate 71.

[0097] Usage method: When it is necessary to use this equipment to polish the inner wall of the container, at this time, through the cooperation of the adjusting component 5 and the multiple extrusion rods 54, the shape of the polishing wheel 4 can be adjusted adaptively according to the shape of the area to be polished by the polishing wheel 4, so that the lower end of the polishing wheel 4 is closely attached to the area to be polished on the inner wall of the container, which helps to improve the subsequent polishing effect of the equipment on the inner wall of the container. At the same time, after the polishing wheel 4 is closely attached to the inner wall of the container, start the servo motor 32, and the polishing wheel 4 can be rotated at a high speed to start polishing the inner wall of the container.

[0098] Meanwhile, when the servo motor 32 runs to drive the rotating shaft 33 to rotate, the fan 35 can be driven to rotate to suck the outside air into the air collecting cylinder 31. At this time, through the air delivery component, this part of the air can be discharged through the two air discharge pipes one 63, the two air discharge pipes two 64 and the two rollers 611 to blow and clean the front and rear positions of the polishing path of the polishing wheel 4, which helps to further improve the polishing effect of the equipment on the inner wall of the container.

[0099] Meanwhile, when a person holds the polishing body 1 by hand to polish the inner wall of the container, if the roughness of the inner wall of the container is relatively high and the frictional resistance generated by the inner wall of the container on the roller 611 is greater than the self-elastic force of the corresponding compression spring 615, at this time, through the cooperation of the force transmission components, the pressing plate 71 can be driven to move downward to compress the gas between the pressing plate 71 and the pressing disc 52. In this way, a uniform downward pressure can be applied to the plurality of pressing rods 54 through the gas, achieving the effect of increasing the polishing pressure of the polishing wheel 4. Moreover, when the pressing plate 71 moves downward under force, through the pressing components, the two friction pads 78 can be driven to approach each other, gradually increasing the rotational resistance of the polishing wheel 4 driven by the rotating shaft 36, that is, gradually reducing the rotational speed of the polishing wheel 4. In this way, when the device polishes the area with relatively high roughness, by combining the increase in the polishing pressure of the polishing wheel 4 and the reduction in the polishing speed of the polishing wheel 4, the polishing effect of the device on the inner wall of the container with relatively high roughness can be improved.

[0100] Meanwhile, when it is necessary to polish the area with relatively high roughness of the container again, after adjusting the polishing wheel 4 to the initial polishing pressure and polishing speed, repeating the above operation can achieve the further fine polishing treatment of the inner wall of the container through the lower polishing pressure and higher polishing speed of the polishing wheel 4.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
