Description

Technical Field

[0001] The invention relates to the technical field of polishing equipment, in particular to a surface polishing equipment for a biomedical concentration tank. Background Art

[0002] Medical concentration tanks are widely used in various solutions concentration, extract refining and other links in the biopharmaceutical process. In the production of biopharmaceutical products, the hygiene and quality requirements of production equipment are extremely high. This is because the product quality is directly related to the health and safety of patients. During the use of the concentration tank, its surface condition has an important impact on the entire production process; on the one hand, the inner surface of the concentration tank is in direct contact with the biopharmaceutical solution. If the surface is not smooth enough, it is easy to cause solution residues. These residual solutions may breed bacteria and microorganisms, and then contaminate subsequent batches of products, seriously affecting the purity and quality of biopharmaceutical products. Moreover, the rough surface may cause local turbulence or dead corners, affecting the uniformity of solution concentration, resulting in uneven product quality; on the other hand, for the outer surface of the concentration tank, in some production environments with high cleanliness requirements, such as aseptic production workshops, uneven or rough surfaces may absorb dust and impurities. These impurities may enter the production environment during the operation of the equipment, causing damage to the cleanliness of the entire production workshop and increasing the risk of product contamination.

[0003] In the prior art, such as the publication number: CN107639523A, an automatic polishing device for the inner and outer walls of a tank body is disclosed, which includes a base, a mounting plate and a polishing mechanism; the base is arranged horizontally, and a first side frame and a second side frame are arranged vertically at both ends of the base, the mounting plate is located above the base and parallel to the base, and the two ends of the mounting plate are respectively connected to the first side frame and the second side frame; the invention is easy to use, the tank body is not easy to shake, the inner and outer walls of the tank body can be polished at the same time, the polishing efficiency is high, and the application range is wide.

[0004] In the above patent, although the device can polish the inner and outer walls of the tank body, the device can only effectively polish the inner wall of the unsealed and completely open tank body. However, in actual applications, the top structure of the existing concentration tank body is not completely open. Most tank bodies are closed except for the eccentric feed hole and the central stirring device installation hole. This special semi-closed structure will make it difficult for the polishing tools of traditional polishing equipment to penetrate into the inner cavity of the tank body to polish its inner wall, greatly reducing the applicability of the polishing equipment.

[0005] Therefore, we propose a surface polishing device for biomedical concentration tanks to solve the above-mentioned problems. Summary of the invention

[0016] Preferably, the tank body is placed between the turntable and the end of the turntable.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. When the inner wall of the tank needs to be polished, the angle modulation motor is started to drive the angle modulation frame to rotate so that it is parallel to the lifting frame, and then the lifting motor is started to drive the spur gear to rotate, and the rack is used to drive the lifting frame to perform lifting and lowering movements. With the cooperation of the angle modulation component, the inner polishing component is sent into the interior of the tank from the inclined tank mouth of the tank.

[0018] 2. When it is necessary to adjust the circular motion diameter of the inner polishing sand roller, the electric push rod is extended to make the worm on the telescopic plate mesh with the worm wheel at the end of the threaded rod. The adjusting motor is started when the worm and the worm wheel are meshed, driving the worm to rotate. Since the worm wheel is connected to the threaded rod, the threaded rod will rotate accordingly. Since the threaded seat is fixed on the surface of the frame sleeve and is threadedly connected to the threaded rod, the rotation of the threaded rod will cause the frame sleeve to move relative to the rotating frame, thereby changing the diameter of the circular motion of the inner polishing sand roller, ensuring that polishing operations can be achieved when facing concentration tanks of various specifications, significantly improving the versatility and work efficiency of the equipment.

[0019] 3. Under normal conditions, the spring generates thrust on the movable plate, so that the ratchet plate and the locking ratchet remain in a bite state to prevent the threaded rod from rotating. When it is necessary to adjust the circular motion diameter of the inner polishing sand roller, the U-shaped frame is squeezed by the pressure rod to overcome the thrust of the spring, so that the movable plate and the ratchet plate are separated from the locking ratchet, unlocking the threaded rod and allowing it to rotate under the action of the adjustment motor to adjust the diameter. This locking and unlocking mechanism is simple and reliable, which can effectively ensure the stability and accuracy of the adjustment component during operation and improve the working reliability and polishing quality of the entire polishing equipment.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-13 The present invention provides a technical solution: a surface polishing device for a biomedical concentration tank, comprising a base 1 and a tank body 12, a frame 110 is installed on the top of the base 1, a translation motor 2 is installed at a position away from the frame 110 on the top of the base 1, a lead screw 21 is installed at the output end of the translation motor 2, and the outer wall of the lead screw 21 is installed on the top of the base 1 near the distal end through a bearing seat, and a polishing mechanism is also provided on the top of the base 1, and the polishing mechanism includes: A lateral fixing assembly 3 is installed on the top of the base 1 and is used for centering and clamping the tank body 12; The longitudinal fixing assembly 4 is mounted on the lateral fixing assembly 3 and can drive the tank body 12 to rotate; An external polishing assembly 5 is mounted on the top of the base 1 and is used to polish the outer wall of the tank body 12; The lifting assembly 6 is installed on the frame 110. The lifting assembly 6 includes a fixed frame 61 installed on the frame 110. A lifting frame 62 is provided inside the fixed frame 61. Both sides of the lifting frame 62 are slidably connected to the inner wall of the fixed frame 61 through a slide rail and a slider, and the lifting frame 62 can perform lifting movement inside the fixed frame 61. The angle modulation component 7 is installed at the bottom of the lifting frame 62. The angle modulation component 7 includes an angle modulation motor 71 and an angle modulation frame 72. The angle modulation frame 72 is arranged at a position near the bottom of the inner side of the lifting frame 62. The angle modulation motor 71 is installed on the outer wall of the lifting frame 62. The output end of the angle modulation motor 71 movably penetrates the outer wall of the lifting frame 62 and is fixedly connected to the angle modulation frame 72. The angle modulation motor 71 can drive the angle modulation frame 72 to rotate, so that the angle modulation frame 72 is parallel or vertical to the fixed frame 61. When the angle modulation frame 72 is parallel to the fixed frame 61, the lifting movement of the lifting frame 62 can make the angle modulation component 7 enter or exit the interior of the tank body 12 from the inclined tank mouth of the tank body 12. A disc frame 73 is installed on the outer surface of the angle modulation frame 72 away from the angle modulation motor 71. The rotating assembly 8 is mounted on the disc frame 73; The inner polishing assembly 9 is mounted on the rotating assembly 8, and the rotating assembly 8 can make the inner polishing assembly 9 perform a circular motion, so as to polish the inner wall of the tank body 12; An adjusting component 10, mounted on the rotating component 8, is used to adjust the diameter of the circular motion of the inner polishing component 9; The locking assembly 11 is installed on the rotating assembly 8 and is used to lock the adjusting assembly 10 .

[0024] Specifically, the translation motor 2 cooperates with the lead screw 21 to accurately control the horizontal position movement of the tank body 12. For example, when the tank body 12 needs to be docked with the outer polishing assembly 5 for outer wall polishing, the translation motor 2 drives the lead screw 21 to rotate, so that the tank body 12 can be accurately moved to the position in contact with the outer polishing sand roller 53, ensuring the smooth progress of the polishing operation; When it is necessary to polish the inner wall of the tank body 12, the lifting assembly 6, with the cooperation of the angle modulation assembly 7, sends the inner polishing assembly 9 into the tank body 12. For example, when the angle modulation frame 72 is adjusted to be parallel to the lifting frame 62 under the drive of the angle modulation motor 71, the lifting frame 62 descends, driving the angle modulation assembly 7 and the subsequent inner polishing assembly 9 to smoothly enter the tank from the inclined tank mouth of the tank body 12.

[0025] like Figure 1-Figure 3 As shown, the lateral fixing assembly 3 includes a translation table 31 threadedly connected to the lead screw 21, and the bottom surface of the translation table 31 is slidably set on the top of the base 1 through symmetrically arranged slide rails and sliders, a clamping motor 32 is installed at the top of the translation table 31 near the edge, a bidirectional lead screw 33 is installed at the output end of the clamping motor 32, the outer wall of the bidirectional lead screw 33 is installed at the top of the translation table 31 near the far end through a bearing seat, a slide seat 34 is symmetrically threaded on the bidirectional lead screw 33, the bottom surface of the slide seat 34 is slidably set on the top of the translation table 31 through symmetrically arranged slide rails and sliders, and clamping rollers 35 are symmetrically rotated on the top of the two slide seats 34.

[0026] Specifically, the clamping motor 32 provides power for the rotation of the bidirectional screw 33. After the tank body 12 is placed on the translation platform 31, the clamping motor 32 is started to drive the bidirectional screw 33 to rotate. In addition, since the bottom surface of the slide 34 is connected to the top of the translation platform 31 through the slide rail and the slider, the rotation of the bidirectional screw 33 will cause the two slides 34 to move relative to or toward each other. During the movement of the slide 34, the clamping roller 35 on the top of the slide 34 gradually approaches the tank body 12 from both sides, and finally clamps the tank body 12 in a centering manner. At the same time, when the tank body 12 rotates under the action of the longitudinal fixing assembly 4, the clamping roller 35 rotates relative to the tank body 12 to prevent the clamping roller 35 from locking the tank body 12, thereby ensuring the rotation of the tank body 12.

[0027] like Figure 1-Figure 3 As shown, the longitudinal fixing assembly 4 includes: A support frame 41 is installed at the middle position on the top of the translation stage 31, and a turntable 42 is rotatably installed on the top of the support frame 41 through a plane bearing; The mounting frame 43 is installed at the middle position on the side of the translation stage 31, and a cylinder 44 is installed on the top of the mounting frame 43. The telescopic end of the cylinder 44 slides through the top of the mounting frame 43 and extends downward. A motor frame 45 is installed on the telescopic end of the cylinder 44. A rotating motor 46 is installed on the bottom of the motor frame 45. The output end of the rotating motor 46 movably passes through the bottom surface of the motor frame 45 and extends downward. A turntable 47 is installed on the output end of the rotating motor 46.

[0028] Specifically, in the initial state, the telescopic end of the cylinder 44 is in a retracted state, and the turntable 47 is separated from the tank body 12. When the tank body 12 needs to be rotated, the telescopic end of the cylinder 44 extends out, driving the turntable 47 at the output end of the rotating motor 46 to descend until it is in close contact with the tank body 12. Then the rotating motor 46 is started, and the friction between the turntable 47 and the tank body 12 drives the tank body 12 to rotate on the turntable 42, so that the outer wall of the tank body 12 can be evenly contacted with the outer polishing roller 53 of the outer polishing assembly 5, thereby achieving an efficient and uniform outer wall polishing effect.

[0029] like Figure 2 and Figure 4 As shown, the external polishing assembly 5 includes a bracket 51 installed on the top of the base 1 and away from the translation motor 2, an external polishing motor 52 is installed on the top of the bracket 51, the output end of the external polishing motor 52 movably passes through the top of the bracket 51 and extends upward, and an external polishing sand roller 53 is installed on the output end of the external polishing motor 52.

[0030] Specifically, the external polishing component 5 is directly responsible for polishing the outer wall of the tank body 12. The external polishing motor 52 drives the external polishing sand roller 53 to rotate at high speed. When the tank body 12 rotates driven by the longitudinal fixing component 4 and contacts the external polishing sand roller 53 under the action of the translation motor 2, the external polishing sand roller 53 removes defects and unevenness on the surface of the outer wall through friction with the outer wall of the tank body 12, thereby improving the smoothness of the outer wall.

[0031] like Figure 5-Figure 8 As shown, a rack 63 is installed on the surface of one side of the lifting frame 62, and a lifting motor 64 is installed on the surface of one side of the fixed frame 61. The output end of the lifting motor 64 movably passes through the outer surface of the fixed frame 61 and extends to the inside. A rotating shaft 65 is installed on the output end of the lifting motor 64. One end of the rotating shaft 65 is rotatably set on the inner wall of one side of the fixed frame 61. A spur gear 66 is fixedly sleeved on the outer wall of the rotating shaft 65 near the middle, and the spur gear 66 is meshed and connected with the rack 63.

[0032] Specifically, the fixed frame 61 of the lifting assembly 6 is connected to the lifting frame 62 through a slide rail and a slider, which ensures the stability and accuracy of the lifting frame 62 during the lifting process. When the inner wall of the tank body 12 needs to be polished, the lifting assembly 6, with the cooperation of the angular position adjustment assembly 7, sends the inner polishing assembly 9 into the tank body 12.

[0033] like Fig.10 and Fig.11 As shown, the rotating assembly 8 includes: The driving motor 81 is fixedly mounted on one end surface of the disc frame 73, and the output end of the driving motor 81 movably passes through the end surface of the disc frame 73 and extends to the other side; The fixed seat 83 is installed on the other end face of the disc frame 73. The outer wall of the fixed seat 83 is rotatably provided with a rotating seat 82, and the inner end face of the rotating seat 82 is fixedly connected to the output end of the driving motor 81. The outer end face of the rotating seat 82 is fixedly connected to a rotating frame 84, and the outer surface of the rotating frame 84 is slidably sleeved with a frame sleeve 85.

[0034] Specifically, when the driving motor 81 is started, it can drive the rotating seat 82 to rotate around its axis, and the fixed seat 83 provides a rotating support for the rotating seat 82, so that it can rotate stably on the disc frame 73. When the rotating seat 82 rotates, it drives the rotating frame 84 and the frame sleeve 85 to make a circular motion, thereby providing the internal polishing assembly 9 installed on the frame sleeve 85 with the power and trajectory basis for the circular motion. In addition, the sliding sleeve relationship between the rotating frame 84 and the frame sleeve 85 enables the frame sleeve 85 to slide on the rotating frame 84 when adjusting the diameter of the circular motion of the internal polishing sand roller 910 in the internal polishing assembly 9.

[0035] like Fig.11 As shown, the inner polishing assembly 9 includes: The bevel gear disc 91 surrounds the outer periphery of the rotating seat 82 and is fixedly connected to the end surface of the disc frame 73; A round shaft 93, the outer wall of which is rotatably sleeved with a first shaft seat 911 fixed on the surface of the rotating frame 84, one end of which is mounted with a driving bevel gear 92 meshing with the bevel gear plate 91, and the other end of which is mounted with a cross shaft 94; The shaft sleeve 95 is slidably sleeved on the surface of the cross shaft 94, and the outer wall of the shaft sleeve 95 is rotatably sleeved with a second shaft rod seat 912 fixed on the surface of the frame sleeve 85, and a driven bevel gear 96 is installed at one end of the shaft sleeve 95; The shaft frame 97 is installed on the surface of the frame sleeve 85, and the inner side of the shaft frame 97 is provided with a linkage bevel gear 98 meshing with the driven bevel gear 96, and a mounting column 99 is installed at one end of the linkage bevel gear 98, and the outer surface of the mounting column 99 is movable through the inner wall of the shaft frame 97 and extends outward, and the outer wall of the mounting column 99 is sleeved with an inner polishing sand roller 910.

[0036] Specifically, the bevel gear 91 is a fixed component and is fixedly connected to the end face of the disc frame 73, providing a stable meshing basis for the active bevel gear 92. When the rotating seat 82 rotates under the drive of the driving motor 81, the active bevel gear 92 at one end of the circular shaft rod 93 will rotate around its own axis due to the meshing with the bevel gear 91, thereby driving the circular shaft rod 93 to rotate, and the cross shaft 94 at the other end of the circular shaft rod 93 transmits the rotational motion to the sleeve 95, and the driven bevel gear 96 at one end of the sleeve 95 rotates accordingly, and the driven bevel gear 96 is meshed with the linkage bevel gear 98, further driving the mounting column 99 and the inner polishing roller 910 to rotate. In addition, the sliding sleeve connection relationship between the cross shaft 94 and the sleeve 95 enables the sleeve 95 to slide on the cross shaft 94 when adjusting the diameter of the circular motion of the inner polishing roller 910 in the inner polishing assembly 9.

[0037] like Fig.12 and Fig.13 As shown, the adjustment assembly 10 includes: The fixed plate 101 is mounted on the inner wall of the angle adjustment frame 72. An electric push rod 102 is mounted on the outer surface of one side of the fixed plate 101 near the middle, and the electric push rod 102 is vertically arranged relative to the frame sleeve 85. A telescopic plate 103 is mounted on the telescopic end of the electric push rod 102. A guide rod 104 is slidably penetrated through the surface of one side of the telescopic plate 103 near the four corners, and the end of the guide rod 104 is fixedly connected to the surface of the fixed plate 101. An adjusting motor 105 is mounted on the surface of the telescopic plate 103 on the side opposite to the electric push rod 102. A worm 106 is mounted on the output end of the adjusting motor 105. A pressure rod 107 extending outward is also mounted on the telescopic plate 103. A threaded rod 108, a worm gear 1010 is mounted on the end surface of the threaded rod 108 away from the frame sleeve 85, a locking ratchet 109 is fixedly sleeved on the outer wall of the threaded rod 108 near the worm gear 1010, and a third shaft rod seat 1011 fixed on the surface of the rotating frame 84 is rotatably sleeved on the outer wall of the threaded rod 108 near the locking ratchet 109; The threaded seat 1012 is fixedly mounted on the surface of the frame sleeve 85 near the edge, and is threadedly sleeved on the surface of the threaded rod 108 .

[0038] Specifically, when it is necessary to adjust the diameter of the circular motion of the inner polishing sand roller 910, the electric push rod 102 extends or retracts to make the worm 106 on the telescopic plate 103 engage or disengage with the worm wheel 1010 at the end of the threaded rod 108. The adjustment motor 105 is started when the worm 106 engages with the worm wheel 1010, driving the worm 106 to rotate. Since the worm wheel 1010 is connected to the threaded rod 108, the threaded rod 108 will rotate accordingly. Since the threaded seat 1012 is fixed on the surface of the frame sleeve 85 and is threadedly connected to the threaded rod 108, the rotation of the threaded rod 108 will cause the frame sleeve 85 to move relative to the rotating frame 84, thereby changing the diameter of the circular motion of the inner polishing sand roller 910.

[0039] like Fig.12 and Fig.13 As shown, the locking assembly 11 includes a movable plate 111 arranged on the outside of the locking ratchet 109, and a ratchet plate 112 cooperating with the locking ratchet 109 is installed on the side surface of the movable plate 111 facing the locking ratchet 109, and a U-shaped frame 113 in contact with the pressure rod 107 is installed on the outer surface of the movable plate 111. The movable plate 111 and the U-shaped frame 113 form a semi-closed structure and surround the outside of the locking ratchet 109. A sliding column 115 is installed on the side surface of the movable plate 111 opposite to the locking ratchet 109, and the sliding column 115 slides through the surface of the rotating frame 84 and extends to the other side. A spring 114 is sleeved on the outside of the sliding column 115, and the two ends of the spring 114 are respectively connected to the movable plate 111 and the surface of the rotating frame 84, and the spring 114 can generate thrust on the movable plate 111.

[0040] Specifically, in a normal state, the spring 114 generates a thrust on the movable plate 111, so that the ratchet plate 112 and the locking ratchet 109 remain in a bite state, preventing the threaded rod 108 from rotating. When it is necessary to adjust the circular motion diameter of the inner polishing sand roller 910, the pressure rod 107 in the adjustment assembly 10 squeezes the U-shaped frame 113 to overcome the thrust of the spring 114, so that the movable plate 111 and the ratchet plate 112 are separated from the locking ratchet 109, and the threaded rod 108 is unlocked, allowing it to rotate under the action of the adjustment motor 105 to adjust the diameter. After the adjustment is completed, the electric push rod 102 returns to its original position, the pressure rod 107 no longer squeezes the U-shaped frame 113, and the spring 114 pushes the movable plate 111 again, so that the ratchet plate 112 is re-engaged with the locking ratchet 109, and the threaded rod 108 is locked, thereby ensuring the stability of the circular motion diameter of the inner polishing sand roller 910.

[0041] like Figure 1 As shown, the can 12 is placed between the turntable 42 and the end of the turntable 47.

[0042] The working principle of this device is as follows: first, the tank body 12 is placed between the turntable 42 and the end of the turntable 47, then, the clamping motor 32 is started to drive the bidirectional screw 33 to rotate, so that the two slides 34 move relatively, and the clamping roller 35 on the top of the slide 34 clamps the tank body 12 in a centering manner, and then, the cylinder 44 is started, and its telescopic end drives the motor frame 45 and the turntable 47 to descend, so that the turntable 47 is in close contact with the tank body 12, thereby realizing the stable lateral positioning of the tank body 12.

[0043] When it is necessary to polish the outer wall of the tank body 12, the translation motor 2 is started to drive the screw 21 to rotate, thereby driving the tank body 12 between the lateral fixing component 3 and the longitudinal fixing component 4 to move linearly along the axial direction of the screw 21 until the tank body 12 contacts the external polishing roller 53 in the external polishing component 5, and then the rotation motor 46 is started to drive the tank body 12 to rotate on the turntable 42 through the turntable 47, providing a rotational motion basis for polishing the outer wall of the tank body 12. At the same time, the external polishing motor 52 in the external polishing component 5 is started to drive the external polishing roller 53 to rotate. During the rotation of the tank body 12, the external polishing roller 53 polishes the outer wall of the tank body 12 to remove defects and unevenness on the surface of the outer wall and improve the smoothness of the outer wall.

[0044] When it is necessary to polish the inner wall of the tank body 12, the angle modulation motor 71 is first started to drive the angle modulation frame 72 to rotate so that it is parallel to the lifting frame 62, and then the lifting motor 64 is started to drive the rotating shaft 65 at its output end to drive the spur gear 66 to rotate. Since the spur gear 66 is meshed and connected with the rack 63 installed on the side surface of the lifting frame 62, the lifting frame 62 can be lifted and lowered inside the fixed frame 61, thereby driving the angle modulation component 7 to enter the interior of the tank body 12 from the inclined tank mouth of the tank body 12. After entering the interior of the tank body 12, the angle modulation frame 72 is driven to rotate by the angle modulation motor 71 so that it is vertical to the lifting frame 62. After that, the tank body 12 is moved by the translation motor 2 in cooperation with the lead screw 21 so that the tank body 12 and the drive shaft on the drive motor 81 are on the same axis.

[0045] Next, the electric push rod 102 in the adjustment component 10 is started, driving the telescopic plate 103 to move, so that the worm 106 is meshed with the worm wheel 1010. At the same time, the pressure rod 107 contacts the U-shaped frame 113 and generates an extrusion force on the U-shaped frame 113. Under the action of the extrusion force, the ratchet plate 112 on the movable plate 111 is separated from the locking ratchet 109, and the threaded rod 108 is unlocked. Then, the adjustment motor 105 is started, and the worm wheel 1010 is driven to rotate through the worm 106, so that the threaded rod 108 rotates. Since the threaded seat 1012 is fixed to the surface of the frame sleeve 85 and the threaded sleeve is connected to the surface of the threaded rod 108, as the threaded rod 108 rotates, the frame sleeve 85 moves relative to the rotating frame 84 , thereby adjusting the diameter of the circular motion of the inner polishing sand roller 910 to adapt to the polishing requirements of the inner wall of the tank body 12 with different diameters. When the circular motion diameter of the inner polishing sand roller 910 is adjusted to a suitable position, the inner polishing sand roller 910 will contact the inner wall of the tank body 12. After that, the worm 106 is driven by the electric push rod 102 to move so that it is separated from the worm wheel 1010. At the same time, the pressure rod 107 contacts the U-shaped frame 113 to separate. Under the action of the elastic force of the spring 114, the ratchet plate 112 engages with the locking ratchet 109 to lock the locking ratchet 109, thereby fixing the position of the threaded rod 108, ensuring the stability of the circular motion diameter of the inner polishing sand roller 910, and ensuring the continuous and stable progress of the polishing operation.

[0046] Afterwards, the driving motor 81 is started, and its output end drives the rotating seat 82 and the rotating frame 84 to rotate, and the frame sleeve 85 also moves accordingly, so that the inner polishing component 9 makes a circular motion. At the same time, since the bevel gear disk 91 surrounding the outer periphery of the rotating seat 82 is fixed, the active bevel gear 92 at the end of the circular shaft rod 93 is meshed with the bevel gear disk 91. When the rotating seat 82 rotates, the active bevel gear 92 rotates, thereby driving the circular shaft rod 93 to rotate, and the cross shaft 94 at the other end of the circular shaft rod 93 drives the sleeve 95 to rotate, and the driven bevel gear 96 at the end of the sleeve 95 drives the linkage bevel gear 98 to rotate, thereby driving the mounting column 99 and the inner polishing sand roller 910 to rotate, so that the inner polishing sand roller 910 is rotating while making a circular motion, so as to polish the inner wall of the tank body 12, remove defects and unevenness on the inner wall, and improve the finish of the inner wall.
