Description

Technical Field

[0001] The 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 from multiple steel plates. During the production process, these steel plates are usually processed into strip-shaped or rib-shaped reinforcement structures to increase the thickness and rigidity of the inner wall of the container formed by subsequent splicing, so as to improve the strength and compression resistance of the overall structure of the container. At the same time, in order to improve the flatness and finish of the inner wall of the container after splicing and reduce the friction damage during subsequent cargo loading and unloading, polishing equipment is usually used to polish the inner wall; However, in the process of polishing the inner wall of the container by polishing equipment, due to personal factors and factors such as light blocking by the inner wall of the container, it is easy to reduce the polishing effect of the equipment on the arc-shaped edges and corners of the irregular parts of the inner wall of the container (i.e., the parts of the structure such as the reinforcement ribs), as well as the polishing uniformity, that is, it is easy to reduce the polishing effect of the equipment on the entire container; Therefore, a container inner wall polishing device is proposed.

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 14 A container inner wall polishing device includes a polishing body 1, a protective cover 2 is fixedly installed on the polishing body 1, a driving component 3 is arranged on the protective cover 2, and an adjusting component 5 is arranged inside the protective cover 2.

[0020] like Figure 1 - Figure 7 As shown, the driving assembly 3 includes a rotating shaft 36 rotatably mounted on the inner top wall of the protective cover 2, a polishing wheel 4 is mounted on the lower end of the rotating shaft 36, and a driving mechanism is installed between the rotating shaft 36 and the protective cover 2; The driving mechanism includes an air collecting tube 31 fixedly mounted on the upper end of the protective cover 2, a servo motor 32 fixedly mounted on the inner top wall of the air collecting tube 31, a rotating shaft 33 fixedly mounted on the driving end of the servo motor 32, and the rotating shaft 33 penetrates and is rotatably mounted on the protective cover 2, a rotating gear 1 34 fixedly mounted on the rotating shaft 33, a rotating gear 2 37 meshing with the rotating gear 1 34 fixedly mounted on the rotating shaft 36, and a wind gathering component is installed on the rotating shaft 33.

[0021] The rotating shaft 36 and the polishing wheel 4 can be connected by a connection method such as a thread that is easy to disassemble. The purpose is to facilitate the staff to replace the polishing wheel 4 after using the equipment 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.

[0022] At the same time, the polishing wheel 4 is made of elastic material, such as rubber, felt and the like, so that when the equipment is polishing the inner wall of the container, the shape of the polishing wheel 4 can be adapted and changed according to the surface shape of the inner wall of the container by adjusting the component 5.

[0023] Existing container inner walls usually have structures such as reinforcing ribs, which are usually strip-shaped or rib-shaped (from Figure 1 It can be seen that Figure 1 The figure shows a partial structural diagram of the inner wall of the container, where the reinforcing ribs can increase the thickness and rigidity of the inner wall of the container, disperse external forces, thereby improving the strength and compression resistance of the overall structure of the container, and helping to extend the service life of the container.

[0024] At the same time, when it is necessary to use the equipment to polish the inner wall of the container, first adjust the component 5 to make the polishing wheel 4 fit tightly to the position to be polished on the inner wall of the container, and then start the servo motor 32. The operation of the servo motor 32 can drive the polishing wheel 4 to rotate and polish the inner wall of the container through the cooperation of the rotating shaft 33, the rotating gear 1 34, and the rotating gear 2 37.

[0025] like Figure 1 - Figure 8 As shown, the adjustment component 5 includes a positioning plate 53 fixedly mounted on the inner wall of the protective cover 2, and a plurality of extrusion rods 54 are penetrated and slidably mounted on the positioning plate 53. An electric telescopic rod 51 is fixedly mounted on the protective cover 2. Two electric telescopic rods 51 are provided. A pressing plate 52 is fixedly mounted on the lower ends of the two electric telescopic rods 51, and the pressing plate 52 is sealingly slidably mounted on the inner wall of the protective cover 2. A pressing mechanism is installed between the extrusion rod 54 and the pressing plate 52, and a speed regulating component 7 is arranged on the outer surfaces of the two electric telescopic rods 51.

[0026] The pressing mechanism includes a plurality of square openings 55 opened on the pressing plate 52, on which round rods 56 are rotatably mounted, and between which torsion springs 57 are fixedly mounted, the round rods 56 and the corresponding square openings 55 are fixedly mounted, and on which pressing plates 58 cooperating with the corresponding extrusion rods 54 are fixedly mounted, and on which the square openings 55 are fixedly mounted, and on which the square openings 55 are fixedly mounted, and the extrusion rods 54 are sealed and penetrated through and slidably mounted on the corresponding sealing rings 511, and a limiting component is installed between the square openings 55 and the extrusion rods 54.

[0027] The limiting component includes a plurality of slide grooves 510 formed on the pressing plate 52 , and the slide grooves 510 are all connected to the corresponding square openings 55 . Slide blocks 59 are fixedly mounted on the extrusion rods 54 , and the slide blocks 59 are slidably mounted on the corresponding slide grooves 510 .

[0028] from Figure 7 It can be seen that the inner wall of the container is usually in the form of strip-shaped reinforcement ribs and the like, and the polishing wheel 4 is mostly flat-bottomed. Therefore, when the staff uses the equipment to polish the inner wall of the container, it is difficult for the lower end of the polishing wheel 4 to completely fit with the curved edges and corners on both sides of the raised part of the inner wall of the container, which may easily lead to these parts not being fully polished and prone to polishing dead corners, thereby affecting the overall polishing effect of the inner wall of the container. At the same time, when the equipment is manually moved to polish the inner wall of the container, it is difficult to maintain the same polishing pressure on the curved edges and flat parts of the inner wall due to the influence of human factors, thereby easily reducing the uniformity of the overall polishing of the inner wall of the container by the equipment.

[0029] When the equipment is needed to polish the inner wall of a container, the polishing wheel 4 is manually aligned and attached to the strip-shaped raised part of the inner wall of the container (such as Figure 7 The state shown in FIG. 1 is shown in FIG. 1 ), and then the two electric telescopic rods 51 are started. At this time, the operation of the two electric telescopic rods 51 will drive the pressing plate 52 to move downward (as shown in FIG. 1 ). Figure 7 In the process of the pressing plate 52 moving downward, the pressing plates 58 thereon will exert downward pressure on the corresponding pressing rods 54, thereby driving the multiple pressing rods 54 to move downward together; At this time, when the reaction force of the polishing wheel 4 on the corresponding multiple extrusion rods 54 is greater than the elastic force of the corresponding multiple torsion springs 57, the multiple extrusion rods 54 located in the middle of the polishing wheel 4 will press the corresponding pressing plate 58 upward to make it rotate upward (such as Figure 8 In the direction shown, a plurality of extrusion rods 54 located on both sides of the polishing wheel 4 (i.e., above the arc-shaped edges and corners on both sides of the raised part of the inner wall of the container) will continue to move downward to cooperate in pressing the two sides of the polishing wheel 4 until the two sides of the polishing wheel 4 are tightly fitted with the arc-shaped edges and corners on both sides of the raised part of the inner wall of the container, which can help improve the subsequent use of the equipment, the polishing effect and polishing uniformity of the plane and arc-shaped edges and corners of the raised part of the inner wall of the container, and help improve the equipment's overall polishing effect on the inner wall of the container.

[0030] At the same time, when the equipment polishes the recessed part of the inner wall of the container, the polishing wheel 4 gradually approaches the recessed part of the inner wall of the container, through the above operation, the polishing wheel 4 can automatically adjust its own shape according to the shape of the area to be polished, which helps to improve the overall polishing effect and polishing uniformity of the equipment on the inner wall of the container.

[0031] At the same time, it is arranged that when the polishing wheel 4 is completely in contact with the area to be polished on the inner wall of the container, the upper ends of the multiple extrusion rods 54 are all located above the pressing plate 52, that is, the resistance exerted by the multiple extrusion rods 54 on the corresponding pressing plates 58 makes the multiple pressing plates 58 in a vertical state, and the multiple sliders 59 are all moved out of the corresponding slide grooves 510.

[0032] When it is necessary to polish other irregular areas of the inner wall of the container, or after the polishing of the inner wall of the container is completed, the two electric telescopic rods 51 are started again to drive the pressing plate 52 to move up and reset. When the sliders 59 above the multiple squeezing rods 54 contact the lower ends of the corresponding slide grooves 510, the resistance applied by the multiple squeezing rods 54 to the corresponding pressing plates 58 disappears. At this time, the elastic force of the multiple torsion springs 57 can make the multiple round rods 56 drive the corresponding pressing plates 58 to rotate clockwise and reset (such as Figure 8 In the direction shown), at this time, multiple pressing plates 58 cooperate with torsion springs 57 to apply upward resistance to the corresponding extrusion rods 54, and the pressing plate 52 cooperates with sliders 59 through multiple slide grooves 510 to apply upward thrust to the corresponding extrusion rods 54, 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, thereby facilitating the subsequent shape adjustment of the polishing wheel 4 according to the shape of the area to be polished on the inner wall of the container.

[0033] At the same time, when the extrusion rod 54 is forced to move upward or downward (such as Figure 8 In the direction shown), through the cooperation of the positioning plate 53 and the corresponding sealing ring 511, the movement of the multiple extrusion rods 54 can be limited, which can help improve the effect of the forced movement of the multiple extrusion rods 54 on the shape adjustment of the polishing wheel 4.

[0034] like Figure 4 - Figure 6 , Fig. 9 - Fig.11 As shown, the protective cover 2 is provided with a cleaning assembly 6, which includes a support plate 65 fixedly mounted on the side wall of the protective cover 2. Two support plates 65 are provided, and threaded openings are provided on both support plates 65, and threaded rods 66 are threadedly mounted on the threaded openings. A cover body 67 is rotatably installed at the lower end of the two threaded rods 66, an air delivery component is commonly installed between the two cover bodies 67 and the air collecting cylinder 31, a rotating rod 68 is rotatably installed on the inner wall of the two cover bodies 67, a roller 611 is fixedly installed on the two rotating rods 68, a rebound component is commonly installed between the two rotating rods 68 and the two cover bodies 67, and a force transmission component is commonly installed between the two rotating rods 68 and the extrusion plate 71.

[0035] The wind collecting component includes a fan 35 fixedly mounted on the rotating shaft 33, and the wind collecting cylinder 31 is provided with an air inlet, and two air inlets are provided, and a filter screen is fixedly mounted on both air inlets (drawn but not marked in the figure, from Fig.10 can be seen in ).

[0036] The air delivery component includes a one-way air delivery pipe 1 61 fixedly connected to the air collecting tube 31, and one end of the one-way air delivery pipe 1 61 passes through and is fixedly installed on the corresponding support plate 65, the air collecting tube 31 is fixedly connected with a one-way air delivery pipe 2 62, the one-way air delivery pipe 2 62 is fixedly connected with an air supply pipe 620, and one end of the air supply pipe 620 passes through and is fixedly installed on the corresponding support plate 65, the one-way air delivery pipe 1 61 and the air supply pipe 620 are both fixedly connected with an exhaust pipe 1 63, and the one-way air delivery pipe 1 61 and the air supply pipe 620 are both fixedly connected with an exhaust pipe 2 64; Wind collecting cylinders 69 are rotatably mounted on the two rotating rods 68, and the two wind collecting cylinders 69 are sealed and penetrated and rotatably mounted on the corresponding rollers 611. Branch pipes 610 are fixedly connected between the two exhaust pipes 63 and the corresponding wind collecting cylinders 69, and the two branch pipes 610 are sealed and penetrated and fixedly mounted on the corresponding cover bodies 67.

[0037] When the equipment is used 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 can easily reduce the polishing effect of the equipment on its inner wall. At the same time, impurities such as debris generated during the polishing process can easily hit the inner wall of the container again, causing new tiny scratches or pits, which can also easily reduce the polishing effect of the equipment on the inner wall of the container.

[0038] When the servo motor 32 is running, the polishing wheel 4 is driven to rotate to polish the inner wall of the container through the cooperation of the rotating shaft 33 and the rotating shaft 36. At this time, the rotation of the rotating shaft 33 can drive the fan 35 to rotate to suck the external air into the air collecting tube 31 through the two air inlets. The air entering the air collecting tube 31 will eventually flow into the two exhaust pipes 1 63 and the two exhaust pipes 2 64 along the cooperation of the one-way air supply pipe 1 61 and the one-way air supply pipe 2 62 and the air supply pipe 620, and finally be ejected from the two exhaust pipes 1 63 and the two exhaust pipes 2 64. Part of the gas that enters the two exhaust pipes 63 will enter the two rollers 611 along the corresponding branch pipes 610 and the air collecting cylinder 69, and finally be ejected from the multiple circular holes opened at the lower ends of the two rollers 611 (from Fig.11 As can be seen in the figure, a plurality of circular holes are provided on both rollers 611, so that during the process of manually moving the equipment to polish the inner wall of the container (such as Fig. 9In the direction shown), through the cooperation of the two exhaust pipes 1 63 with the corresponding exhaust pipe 2 64 and the roller 611, the impurities in the front and rear positions of the equipment's polishing route (i.e., the areas on the container's inner wall to be polished and after polishing) are blown and cleaned, which can help improve the equipment's polishing effect on the container's inner wall and reduce the situation where impurities on the container's inner wall to be polished area and impurities such as debris generated by polishing affect the polishing effect of the container's inner wall.

[0039] Combined with Fig. 9 and Fig.10 It can be seen that two fixing blocks are fixedly installed on the upper ends of the two cover bodies 67, and the two exhaust ducts 1 63 and the two exhaust ducts 2 64 are all penetrated and fixedly installed on the corresponding fixing blocks. The positions of the corresponding exhaust ducts 1 63 and the exhaust ducts 2 64 are fixed by multiple fixing blocks, which can help improve the stability of the exhaust ducts 1 63 and the exhaust ducts 2 64 cooperating to jet cleaning the inner wall of the container, and a protrusion is also provided on the upper end of the protective cover 2, which can help improve the stability of the one-way air supply duct 2 62 to the air supply duct 620.

[0040] like Fig. 9 - Fig.13 As shown, the speed regulating assembly 7 includes an extrusion plate 71 sealed and slidably installed between the protective cover 2 and the rotating shaft 36, and the extrusion plate 71 seals and penetrates and is slidably installed between the two electric telescopic rods 51, and an extrusion component is installed between the extrusion plate 71 and the rotating shaft 36.

[0041] The rebound component includes brackets 612 respectively fixedly mounted on the two rotating rods 68, arc grooves 613 are provided on the two cover bodies 67, moving blocks 614 are fixedly mounted on one end of the two brackets 612, and the two moving blocks 614 are slidably mounted on the corresponding arc grooves 613, compression springs 615 are fixedly mounted on the two arc grooves 613, and the two compression springs 615 are fixedly connected to the corresponding moving blocks 614.

[0042] The force transmission component includes parallel shaft gears 616 respectively fixedly mounted on two rotating rods 68, and limit plates (not shown in the figure but not marked) are fixedly mounted on two support plates 65. Fig.12 As can be seen in the figure, connecting rods 617 are penetrated and slidably installed on the two limit plates, and rack rods 618 meshing with corresponding parallel axis gears 616 are fixedly installed at the lower ends of the two connecting rods 617; The upper ends of the two connecting rods 617 are fixedly installed with telescopic rods 619, and the lower ends of the two telescopic rods 619 are fixedly connected to the extrusion plate 71, and the two telescopic rods 619 pass through and are slidably installed on the protective cover 2. A limited displacement plate 72 is fixedly installed on the inner wall of the protective cover 2, and two limited displacement plates 72 are provided.

[0043] like Fig.13 As shown, when set in the initial state, the lower end of the polishing wheel 4 is flush with the lower ends of the two rollers 611.

[0044] When the polishing wheel 4 is in close contact with the part to be polished on the inner wall of the container, and the two rollers 611 are in close contact with the inner wall of the container, the height of the two rollers 611 needs to be adjusted according to the movement direction of the polishing device held by a person, that is, the polishing direction. If the polishing body 1 is moved from top to bottom to polish the inner wall of the container (such as Fig. 9 In the direction shown), it is necessary to first rotate the upper threaded rod 66 so that the upper cover body 67 drives the corresponding roller 611 to move and separate from the inner wall of the container, so that the roughness of the inner wall of the container can be automatically detected by the lower roller 611 in the subsequent process, and the polishing pressure and polishing speed of the polishing wheel 4 can be automatically adjusted according to the detection result to avoid the situation where the upper roller 611 affects the detection result. On the contrary, when the polishing body 1 is moved from bottom to top by hand to polish the inner wall of the container, it is necessary to manually rotate the lower threaded rod 66 to separate the lower roller 611 from the inner wall of the container.

[0045] The roughness of the inner wall of different containers is easily different due to the influence of factors such as raw materials and processing technology. When the roller 611 moves on the inner wall surface of the container with higher roughness, the friction resistance generated by the inner wall of the container on the movement of the roller 611 is greater than the 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 relatively small, the friction resistance generated by the inner wall of the container on the moving roller 611 is difficult to overcome the elastic force of the corresponding compression spring 615, that is, it is difficult to make the roller 611 rotate and move. If the polishing wheel 4 moves to the right (such as Fig.13 When the inner wall of the container is rough, the frictional resistance of the inner wall of the container on the right roller 611 will cause the right roller 611 to rotate clockwise around the corresponding rotating rod 68 (as shown in FIG. Fig.13 In the direction shown in the figure), at this time, through the cooperation of the corresponding rotating rod 68 with the corresponding parallel axis gear 616, the rack rod 618, and the connecting rod 617, the corresponding telescopic rod 619 can be driven to press the extrusion plate 71 to move downward (as shown in the figure). Fig.13 direction shown).

[0046] When set in the initial state, a large amount of gas is stored between the extrusion plate 71 and the pressing plate 52 (at the same time, the cooperation between the sealing ring 511 and the corresponding extrusion rod 54 can achieve sealing of the gas above the pressing plate 52). When the roughness of the inner wall of the container is relatively high, at this time, the roller 611 in the polishing direction of the equipment cooperates with the corresponding connecting rod 617 and the telescopic rod 619 to drive the extrusion plate 71 to move downward, and compress the gas between the extrusion plate 71 and the pressing plate 52, so as to increase the pressure of this part of the gas. At the same time, through the fluidity of the gas, the gas with increased pressure can evenly generate downward pressure on multiple extrusion rods 54, so that multiple extrusion rods 54 cooperate to squeeze the polishing wheel 4 downward, so as to increase the polishing pressure of the polishing wheel 4 on the area to be polished on the inner wall of the container, which helps to improve the sufficiency of the equipment in polishing the inner wall of the container with higher roughness, and helps to improve the polishing effect of the equipment on the inner walls of containers with different roughness.

[0047] When the roughness of the inner wall 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 cause poor polishing effect in the area with higher roughness, or over-polishing in the area with lower roughness. Therefore, timely adjusting the polishing pressure of the polishing wheel 4 according to the roughness of the inner wall of the container can help further improve the polishing effect of the equipment on the inner wall of the container.

[0048] At the same time, the higher the roughness of the inner wall of the container, the greater the friction resistance it generates on the corresponding roller 611. At this time, the longer the downward distance driven by the rotation of the roller 611 to move the extrusion plate 71 is, that is, the extrusion plate 71 cooperates with multiple extrusion rods 54 through compressed gas, and the greater the downward pressure generated on the polishing wheel 4, the smaller the downward pressure is. In this way, the polishing pressure of the polishing wheel 4 can be automatically adjusted according to the roughness of the inner wall of the container.

[0049] When the device moves to an area with lower roughness, the frictional resistance of the area to the corresponding roller 611 decreases. At this time, under the 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. In this process, the extrusion plate 71 can be driven to move upward and reset through the cooperation of the corresponding parallel shaft gear 616 and the telescopic rod 619 (such as Fig.13 In the direction shown), that is, the extrusion force of the multiple extrusion rods 54 on the polishing wheel 4 is gradually reduced.

[0050] At the same time, a one-way air supply pipe 61 and an air supply pipe 620 are provided, which are located between the corresponding support plate 65 and the cover body 67 and are made of elastic material. The purpose is to facilitate the adjustment of the height of the drum 611 as required, so that the corresponding exhaust pipe 1 63 and the exhaust pipe 2 64 can cooperate to produce a compression or stretching effect on the corresponding one-way air supply pipe 61 and the air supply pipe 620.

[0051] The purpose of setting two limit plates 72 and adding two telescopic rods 619 between the two connecting rods 617 and the extrusion plate 71 is that when the height of the roller 611 on one side of the polishing wheel 4 is adjusted according to the moving direction of the polishing wheel 4, an upward driving force (such as 1) is applied to the corresponding rack rod 618 through the corresponding parallel axis gear 616. Fig.13 As shown in the direction, the rack rod 618 on the side can drive the corresponding connecting rod 617 and the telescopic rod 619 to move upward together. However, since the telescopic rod 619 on the other side cooperates with the two limit plates 72 to limit the movement of the extrusion plate 71, the rack rod 618 on the side can cooperate with the corresponding connecting rod 617 to move upward, which will stretch the corresponding telescopic rod 619. At the same time, if the roller 611 on one side rotates, the extrusion plate 71 will be pressed downward by the corresponding telescopic rod 619, and the extrusion plate 71 will stretch the telescopic rod 619 on the other side.

[0052] like Fig.13 , Fig.14 As shown, the extrusion component includes a positioning block 73 fixedly mounted on the inner top wall of the protective cover 2, and two positioning blocks 73 are provided. A screw rod 74 is penetrated and rotatably installed on the two positioning blocks 73, and a spur gear 75 is fixedly installed on the two screw rods 74. A rack rod 76 is fixedly mounted on the extrusion plate 71, and two rack rods 76 are provided, and the two rack rods 76 are meshed with corresponding spur gears 75. Fixing members 77 are threadedly installed on the two screw rods 74, and friction pads 78 are fixedly installed on the two fixing members 77.

[0053] The two friction pads 78 are both made of elastic material, such as polyurethane material, and in the initial state, the two friction pads 78 are both in contact with the surface of the rotating shaft 36 .

[0054] When the surface roughness of the inner wall of the container is high, the roller 611 on the side of the polishing forward direction of the driving device is forced to rotate and drive the extrusion plate 71 to move downward. At this time, the extrusion plate 71 will drive the two rack rods 76 to move downward together (such as Fig.14 In the process of the two rack rods 76 moving downward, the two fixing members 77 can be driven to drive the corresponding friction pads 78 to approach each other through cooperation with the corresponding spur gears 75 and the screw rods 74 (the threads of the two screw rods 74 are arranged in opposite directions). In the process of the two friction pads 78 approaching each other, the friction resistance to the rotating shaft 36 can be gradually increased, so that when the equipment is polishing the inner wall of a container with a relatively high roughness, the effect of the polishing speed of the polishing wheel 4 driven by the rotating shaft 36 can be adaptively reduced; In this way, the polishing pressure of the polishing wheel 4 can be increased by moving the extrusion plate 71 downward, thereby improving the polishing effect of the polishing wheel 4 on the area with higher roughness of the inner wall of the container. At the same time, the polishing speed of the polishing wheel 4 driven by the rotating shaft 36 can be reduced, thereby further improving the polishing effect of the polishing wheel 4 on the inner wall of the container. Since the rougher areas on the inner wall of the container have poor flatness, if a faster polishing speed is used at this time, it is easy to reduce the stability of the contact pressure and friction between the polishing wheel 4 and the inner wall of the container, and it is easy for the polishing wheel 4 to "jump" locally on its surface, thereby generating new scratches and pits. At the same time, at this time, a polishing speed that is too fast is likely to aggravate the friction between the inner wall of the container and the polishing wheel 4, which is likely to aggravate the wear of the polishing wheel 4 and reduce the service life of the polishing wheel 4.

[0055] At the same time, after the roughness area of ​​the container inner wall is initially polished by increasing the polishing pressure of the polishing wheel 4 and reducing the polishing speed of the polishing wheel 4, if further fine polishing is required for this area, the polishing body 1 is first manually held to keep the polishing wheel 4 away from the container inner wall. 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 and reset, and then the above operation is repeated to drive the polishing wheel 4 to polish the area again. At this time, since the roughness of this area is relatively reduced after the previous polishing treatment, that is, the roller 611 on the corresponding side cannot be driven to rotate. Therefore, at this time, the lower polishing pressure and higher polishing speed of the polishing wheel 4 can achieve further fine polishing of the container inner wall, thereby meeting the requirements of different polishing degrees of the container inner wall; At the same time, if the equipment is grinding the inner wall of the container with lower roughness, the friction resistance between the inner wall of the container and the roller 611 cannot drive the roller 611 to rotate. At this time, the equipment can achieve fine polishing of the inside of the container through the lower polishing pressure and higher polishing speed of the polishing wheel 4.

[0056] At the same time from Fig.14 It can be seen that the two rack rods 76 are intermittently meshed with the corresponding spur gears 75, and the tooth blocks on the spur gears 75 and the corresponding rack rods 76 are relatively small, that is, each time the rack rod 76 drives the corresponding spur gear 75 to rotate, the corresponding screw rod 74 drives the corresponding fixing member 77 and the friction pad 78 to move a shorter distance, thereby ensuring that the two friction pads 78 gradually increase the effect of the rotation resistance of the rotating shaft 36 according to the downward movement distance of the extrusion plate 71.

[0057] Instructions for use: When the equipment is needed to polish the inner wall of a container, the shape of the polishing wheel 4 can be adaptively adjusted according to the shape of the part to be polished by adjusting the component 5 and cooperating with the plurality of extrusion rods 54, so that the lower end of the polishing wheel 4 fits tightly with the area to be polished on the inner wall of the container, thereby helping 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 fits tightly with the inner wall of the container, the servo motor 32 is started to make the polishing wheel 4 rotate at high speed to start polishing the inner wall of the container.

[0058] At the same time, when the servo motor 32 drives the rotating shaft 33 to rotate, it can drive the fan 35 to rotate and suck the external gas into the air collecting tube 31. At this time, through the air supply component, this part of the gas can be discharged through two exhaust pipes 1 63, two exhaust pipes 2 64 and two rollers 611, and the front and rear positions of the polishing path of the polishing wheel 4 are blown and cleaned, which helps to further improve the polishing effect of the equipment on the inner wall of the container.

[0059] At the same time, if the inner wall of the container is polished by the polishing body 1 held by hand, the roughness of the inner wall of the container is relatively high, and the friction resistance generated by the inner wall of the container to the roller 611 is greater than the elastic force of the corresponding compression spring 615, the extrusion plate 71 can be driven downward to compress the gas between the extrusion plate 71 and the pressing plate 52 through the cooperation of the force transmission component, so that a uniform downward pressure can be applied to multiple extrusion rods 54 through the gas, thereby increasing the polishing pressure of the polishing wheel 4. In addition, when the extrusion plate 71 is forced to move downward, the two friction pads 78 can be driven to approach each other through the extrusion component, 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. Therefore, when the equipment polishes the area with higher roughness, the polishing effect of the equipment on the inner wall of the container with higher roughness is improved by combining increasing the polishing pressure of the polishing wheel 4 with reducing the polishing speed of the polishing wheel 4.

[0060] At the same time, if it is necessary to polish the area with higher roughness of the container again, after adjusting the polishing wheel 4 to the initial polishing pressure and polishing speed, repeat the above operation, and the lower polishing pressure and higher polishing speed of the polishing wheel 4 can be used to achieve further refined polishing of the inner wall of the container.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
