Technical Field

[0001] The invention relates to the technical field of machine tool processing, and in particular to a grinding and rust removal device for inner and outer walls of a sealed container. Background Art

[0002] During long-term use, rust, oxide layer or residue will form on the inner and outer wall surfaces of the container shell of a sealed container, which will affect the normal use of the container. Therefore, in order to ensure the normal use of the sealed container, the sealed container will be polished and rust-removed.

The above device utilizes a transmission belt, a meshing driving gear and a driven gear to make the scraper and the limit turntable rotate in the opposite direction, so as to ensure that the scraper can strongly scrape off the rust in the pressure vessel.

[0004] In the process of grinding the inside of a sealed container, a rod is usually extended into the sealed container. However, due to the different thicknesses of the rust layer, the scraper may be squeezed and vibrated during rust removal, thereby reducing the rust removal effect on the inner wall of the container. Summary of the invention

[0005] The purpose of the present invention is to solve the disadvantage that in the prior art, a rod extends into the interior of a sealed container, but due to the different thicknesses of the rust layer, the scraper will be squeezed and vibrated during rust removal, thereby reducing the rust removal effect on the inner wall of the container. A device for grinding and rust removal of the inner and outer walls of a sealed container is proposed to solve the problem.

[0007] Preferably, the limit component includes a sliding seat, two bottom limit wheels, two side limit wheels, a control frame, and two top limit wheels. The sliding seat is slidably arranged on the machine tool. The two bottom limit wheels are symmetrically mounted at the bottom of the sliding seat.

The control frame is fixedly mounted on the upper side of the sliding seat. The two top limit wheels are fixedly mounted on the control frame.

[0008] Preferably, a regulation component is arranged in the middle of the sliding seat. The regulation component includes a regulation motor, two regulation rods, and a magnetic suction seat. The regulation motor is fixedly mounted on the side of the sliding seat away from the inner scraping component. The two regulation rods are symmetrically fixedly connected to both sides of the regulation motor, and the ends are respectively connected to the two side limit wheels. The magnetic suction seat is fixedly connected to the side of the sliding seat close to the inner scraping component, and the magnetic suction seat is fixedly connected to the output end of the regulation motor.

[0009] Preferably, the control base includes a bottom plate, a telescopic motor seat, and an extrusion plate. The bottom plate is slidably limited on the machine tool. The telescopic motor seat is fixedly connected to the bottom plate. The telescopic column is fixedly connected to the output end of the telescopic motor seat. The extrusion plate is rotatably sleeved on the telescopic column.

[0010] Preferably, the outer scraping component includes a lead screw, a mounting seat, and an outer cutter head. The lead screw is rotatably mounted inside the mounting opening. The mounting seat is threadedly connected to the lead screw. The outer cutter head is fixedly connected to the upper side of the mounting seat and is used for scraping the outer wall of the container.

[0011] Preferably, the cutter head group includes a fixed seat and two blades. The fixed seat is rotatably mounted at the upper end of the upper control arm. The two blades are fixedly mounted on the fixed seat.

[0012] Preferably, the support component includes a mounting shaft, a support wheel, and a detector. The mounting shaft is rotatably mounted at the end of the lower control arm. The support wheel is fixedly connected to the side of the mounting shaft. The detector is fixedly mounted on the side of the support wheel.

[0013] Preferably, a collection assembly is arranged between the two mounting shafts, and the collection assembly is used for collecting the debris generated by the scraping of the inner scraping and planing assembly.

[0014] Preferably, the collection assembly includes two deflection rods, two elastic members, a collection cover and a plurality of magnetic attraction strips. The two deflection rods are fixedly connected to the side of the mounting shaft away from the support wheel and are on the same straight line as the support wheel. The two elastic members are respectively sleeved on the two deflection rods. The collection cover is fixedly sleeved between the two deflection rods. The collection cover is an arc-shaped cover, and the upper end is fixedly connected to the upper ends of the two control arms. The plurality of magnetic attraction strips are respectively fixedly connected to the upper and lower sides of the collection cover.

[0015] Preferably, the elastic member includes two connecting rings and an energized solenoid. The two connecting rings are fixedly connected to the two ends of the energized solenoid. The two connecting rings are fixedly connected to the deflection rods and are used for magnetic adjustment of the magnetic attraction strips.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The cutter head group and the two support assemblies form a stable triangular structure. When the cutter head group performs scraping treatment, the vibration of the telescopic column caused by the cutter head group is supported by the two support assemblies at the bottom, avoiding the vibration of the cutter head group during use and ensuring the rust removal effect. 2. The two bottom limit wheels can limit the cylindrical container tank from below. Then, according to the diameter of the container, the distance between the two side limit wheels and the position of the top limit wheel are controlled, so as to limit the position of the container to be polished and rust-removed. At the same time, during the scraping process, the container is driven to rotate by a plurality of limit wheels, realizing rapid rust-removing processing of the container. The extrusion force received by the limit wheels during scraping is dispersed by rotation, thus avoiding the external extrusion deformation of the container. 3. The inlet position of the container is sealed by the extrusion plate. The extrusion plate and the magnetic attraction seat clamp and fix the container from both ends of the container. At the same time, the magnetic attraction seat and the extrusion plate will also rotate with the container during the rotation of the container, thus avoiding the flying of the debris generated during polishing from the opening position and reducing the noise generated during scraping. 4. By providing two blades with different protruding angles, the protruding rust layer on the inner wall of the container is pre-treated by the first blade, so as to scrape off the protruding part. The second blade is used to complete further scraping and rust removal. While ensuring the rust removal effect, the service life of the cutter head is improved. 5. Since the inner diameter of the container may change, the container to be polished is detected in advance by an infrared detector, and a pre-position detection of the diameter of the container is carried out. The detected spacing data is digitally transmitted, and then the control system adjusts the expansion and contraction of multiple control arms inside the inner scraping component and the mounting base of the outer scraping component, so that the cutter head group and the outer cutter head can contact the inner and outer walls of the container; 6. The installation shaft drives the deflection rod to rotate, thereby unfolding the collection cover. The collection cover is located directly below the cutter head group and can collect the debris scraped by the cutter head group. At the same time, the magnetic absorption strips on the upper and lower sides of the collection cover are energized through elastic parts to generate magnetism, so as to magnetically absorb and collect the debris scattered inside the container, reducing the later cleaning time.

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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.

[0020] Terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present invention are only for the convenience of clear narration, rather than used to limit the scope of implementation of the present invention. The change or adjustment of their relative relationship, without substantial change in technical content, should also be regarded as the scope of implementation of the present invention.

[0021] Refer to Figures 1-9 , a grinding and rust removal device for the inner and outer walls of a sealed container, comprising: a machine tool 1, a limit component 2 for clamping the sealed container is arranged on one side of the machine tool 1, and a control base 3 is arranged on the other side. An installation opening is formed in the middle of the side of the machine tool 1 close to the limit component 2, and an outer scraping and planing component 6 is arranged inside the installation opening; An inner scraping and planing component 4 is arranged on the side of the control base 3 close to the limit component 2. The inner scraping and planing component 4 includes a telescopic column 41, a control board 42, three control arms 43 and a cutter head group 44. The telescopic column 41 is horizontally and vertically fixedly connected to the side of the control base 3. The control board 42 is fixedly connected to the end of the telescopic column 41, and three installation grooves are equidistantly and annularly formed on the side. The three control arms 43 are respectively rotatably installed inside the installation grooves through rotating shafts, and the ends of the unfolded control arms 43 form an equilateral triangle. The cutter head group 44 is fixedly and rotatably installed at the end of the upper control arm 43; Two support components 7 are respectively rotatably installed at the ends of the two control arms 43 located below. The support components 7 are used to support the upper control arm 43.

[0022] In an embodiment of the above technical solution, the sealed container to be polished is fixed between the limiting components 2. The inner scraping component 4 is transferred into the container by controlling the base 3, and at the same time, the outer scraping component 6 is transferred to the bottom surface of the container. The inner and outer walls of the sealed container are simultaneously scraped and rust-removed by the inner scraping component 4 and the outer scraping component 6; When scraping the inner wall, by controlling the telescopic extension of the three control arms 43, the cutter head group 44 is brought into contact with the inner wall of the container by the two support components 7. The cutter head group 44 and the two support components 7 form a stable triangular structure. When the cutter head group 44 performs scraping treatment, the telescopic column 41 caused by the cutter head group 44 vibrates, and the two support components 7 at the bottom support the cutter head group 44, avoiding the vibration of the cutter head group 44 during use and ensuring the rust-removing effect.

[0023] The preferred technical solution in this embodiment: Refer to Figure 4 and Figure 5 The limiting component 2 includes a sliding seat 21, two bottom limiting wheels 22, two side limiting wheels 23, a control frame 24 and two top limiting wheels 25. The sliding seat 21 is slidably arranged on the machine tool 1. The two bottom limiting wheels 22 are symmetrically installed at the bottom of the sliding seat 21. Two sliding openings are symmetrically formed in the middle of the sliding seat 21. The two side limiting wheels 23 are respectively slidably arranged inside the two sliding openings. The control frame 24 is fixedly installed on the upper side of the sliding seat 21. The two top limiting wheels 25 are fixedly installed on the control frame 24; In the existing device, when placing sealed containers with different diameters, the container is usually limited and clamped by an external clamping device. However, this will cause the clamped position to be unable to be effectively scraped and polished, and such a rigid clamping will cause deformation of the outer side of the container, affecting the normal use of the container; By arranging two bottom limiting wheels 22, the cylindrical container can be limited from below. Then, according to the diameter of the container, the distance between the two side limiting wheels 23 and the position of the top limiting wheels 25 are controlled, so as to limit the position of the container to be polished and rust-removed. At the same time, during the scraping process, the container is driven to rotate by multiple limiting wheels, realizing rapid rust-removing processing of the container. By rotating, the extrusion force received by the limiting wheels during scraping is dispersed, thereby avoiding the external extrusion deformation of the container.

[0024] Refer to Figure 4 and Figure 5, a control component 5 is arranged in the middle of the sliding seat 21. The control component 5 includes a control motor 51, two control rods 52 and a magnetic attraction seat 53. The control motor 51 is fixedly installed on the side of the sliding seat 21 away from the inner scraping and planing component 4. The two control rods 52 are symmetrically and fixedly connected to both sides of the control motor 51, and the ends are respectively connected to the two side limiting wheels 23. The magnetic attraction seat 53 is fixedly connected to the side of the sliding seat 21 close to the inner scraping and planing component 4, and the magnetic attraction seat 53 is fixedly connected to the output end of the control motor 51.

[0025] Since the diameters of the containers to be scraped and planed are different, it is necessary to limit and clamp the sides of the containers through the side limiting wheels 23 on both sides. The control motor 51 drives the two control rods 52 on both sides to expand and contract, so as to change the distance between the two side limiting wheels 23, thereby limiting containers with different diameters.

[0026] At the same time, in order to prevent the container from sliding horizontally during scraping and planing, it is necessary to limit the horizontal position of the container. The control motor 51 is energized into the magnetic attraction seat 53, so that the magnetic attraction seat 53 magnetically limits the position of the container.

[0027] Refer to Figure 3 , the control base 3 includes a bottom plate 31, a telescopic motor seat 32 and a pressing plate 33. The bottom plate 31 is arranged on the machine tool 1 in a limited sliding manner. The telescopic motor seat 32 is fixedly connected to the bottom plate 31. The telescopic column 41 is fixedly connected to the output end of the telescopic motor seat 32. The pressing plate 33 is rotatably sleeved on the telescopic column 41.

[0028] The bottom plate 31 slides on the machine tool 1, thereby driving the inner scraping and planing component 4 to move in position. Since the diameters of the containers to be scraped and polished are different, it is necessary to control the telescopic motor seat 32 to move up and down, thereby driving the horizontal height of the inner scraping and planing component 4 to change, ensuring that different containers can be polished.

[0029] The inlet position of the container is sealed by the pressing plate 33. The pressing plate 33 and the magnetic attraction seat 53 clamp and fix the container from both ends of the container. At the same time, during the rotation of the container, the magnetic attraction seat 53 and the pressing plate 33 will also rotate with the container, thereby preventing the chips generated during polishing from splashing out from the opening position and reducing the noise generated during scraping and planing.

[0030] Refer to Figure 6 , the outer scraping and planing component 6 includes a lead screw 61, a mounting seat 62 and an outer cutter head 63. The lead screw 61 is rotatably installed inside the installation opening. The mounting seat 62 is threadedly connected to the lead screw 61. The outer cutter head 63 is fixedly connected to the upper side of the mounting seat 62 and is used for scraping the outer wall of the container.

[0031] In order to improve the efficiency of rust removal from the container, the outer scraping and planing component 6 and the inner scraping and planing component 4 work simultaneously, so as to quickly perform scraping and rust removal treatment on the inside and outside of the container. When performing external rust removal, the position of the outer tool head 63 is controlled by the lead screw 61, and the distance from the outer tool head 63 to the outer surface of the container is controlled by the mounting seat 62, so as to perform scraping and rust removal treatment on the outside of the container.

[0032] Referring to Figure 7 , the tool head group 44 includes a fixed seat 441 and two blades 442. The fixed seat 441 is rotatably installed at the upper end of the control arm 43 located at the upper end, and the two blades 442 are fixedly installed on the fixed seat 441.

[0033] Since the thickness of the rust layer on the inner wall of the container is different, in order to avoid large impact wear on the tool head caused by the thicker rust layer and reduce the service life of the tool head.

[0034] By providing two blades 442 with different protruding angles, after entering the container, first rotate the fixed seat 441 to make the first blade 442 at the front end deflect first, and perform a pretreatment on the protruding rust layer on the inner wall of the container through the first blade 442, so as to scrape off the protruding part. Then, by rotating the angle of the fixed seat 441, the second blade 442 located at the rear is brought into contact with the inner wall of the container, and further scraping and rust removal are completed through the second blade 442. While ensuring the rust removal effect, the service life of the tool head is improved.

[0035] Referring to Figure 8 , the support component 7 includes a mounting shaft 71, a support wheel 72 and a detector 73. The mounting shaft 71 is rotatably installed at the end of the control arm 43 located at the lower part, the support wheel 72 is fixedly connected to the side of the mounting shaft 71, and the detector 73 is fixedly installed on the side of the support wheel 72.

[0036] After the inner scraping and planing component 4 extends into the container, by rotating the mounting shaft 71, the support wheel 72 is driven to rotate. The support wheel 72 contacts the inner wall of the container. The support wheel 72 is arranged on the side of the tool head group 44 close to the control base 3, so as to ensure that the support wheel 72 contacts the part of the container that has been scraped and planed, and avoid the support wheel 72 contacting the inner wall of the container with different thicknesses, ensuring the stable rotation of the support wheel 72.

[0037] At the same time, when the upper tool head group 44 performs scraping and planing, due to the vibration of the inner scraping and planing component 4 caused by contacting the rust layer, the impact force generated by the vibration is absorbed and transferred by the two lower support wheels 72, thereby reducing the vibration amplitude of the inner scraping and planing component 4 and ensuring the scraping and planing effect of the inner scraping and planing component 4.

[0038] Since the inner diameter of the container may change, the infrared detector 73 is used to detect the container to be polished in advance, perform a pre-position detection of the diameter of the container, digitally transmit the detected spacing data, and then the control system adjusts the expansion and contraction of multiple control arms 43 inside the inner scraping component 4 and the mounting base 62 of the outer scraping component 6, so that the cutter head group 44 and the outer cutter head 63 can contact the inner and outer walls of the container.

[0039] Refer to Figure 8 and Figure 9 , a collection component 8 is arranged between the two mounting shafts 71, and the collection component 8 is used to collect the debris generated by the scraping of the inner scraping component 4; The collection component 8 includes two deflection rods 81, two elastic members 82, a collection cover 83 and a plurality of magnetic attraction strips 84. The two deflection rods 81 are fixedly connected to the side of the mounting shaft 71 away from the support wheel 72 and are on the same straight line as the support wheel 72. The two elastic members 82 are respectively sleeved on the two deflection rods 81. The collection cover 83 is fixedly sleeved between the two deflection rods 81. The collection cover 83 is an arc-shaped cover, and the upper end is fixedly connected to the upper ends of the two control arms 43. The plurality of magnetic attraction strips are respectively fixedly connected to the upper and lower sides of the collection cover 83; The elastic member 82 includes two connecting rings 821 and an energized solenoid 822. The two connecting rings 821 are fixedly connected to both ends of the energized solenoid 822. The two connecting rings 821 are fixedly connected to the deflection rod 81 and are used for magnetic adjustment of the magnetic attraction strip 84.

[0040] Since when scraping the inside of the container, the generated debris will fall into the container. During the rotation of the container, these debris will rotate with the container, and the debris will cause secondary wear to the part of the container that has been scraped inside, resulting in excessive wear inside the container. At the same time, the collision of the debris against the inside of the container will generate noise pollution and affect the processing environment.

[0041] By arranging the collection component 8 on the two lower control arms 43, the deflection rod 81 is driven to rotate by the mounting shaft 71, so that the collection cover 83 is unfolded. The collection cover 83 is located directly below the cutter head group 44, and can collect the debris scraped by the cutter head group 44. At the same time, the magnetic attraction strips 84 on the upper and lower sides of the collection cover 83 are energized through the elastic member 82, thereby generating magnetism, and magnetically absorbing and collecting the debris scattered in the container, reducing the later cleaning time.

[0042] At the same time, the deflection rod 81 is made of an elastic material. After cleaning to the end of the container, the deflection shaft can deflect, ensuring the normal scraping of the cutter head group 44. At the same time, the elastic member 82 is arranged inside the deflection shaft to strengthen the overall anti-bending ability of the deflection shaft. After the bending ends, it can also accelerate the reset of the deflection rod 81.

[0043] Since the side of the collection cover 83 is fixedly connected to the side of the elastic rod, when debris falls onto the surface of the collection cover 83, it will cause an impact on the collection cover 83, resulting in deformation of the collection cover 83. Prolonged impact wear can cause deformation and damage of the collection cover 83. Through the elastic deformation of the elastic member 82, a buffering effect can be achieved. When the inside of the energized solenoid 822 is energized, magnetism is generated on the magnetic strip 84, thereby magnetically fixing the fallen debris to prevent the movement of the debris and playing a protective role for the collection cover 83.

[0044] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. 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 inventive concept, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
