Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of winding production, in particular to a spiral extrusion seamless winding production process and production equipment. BACKGROUND

[0002] The winding production process refers to the process of coating and winding a specified material on the surface of a product, such as winding and coating a protective film on the surface of a formed storage tank to protect the performance of the product.

[0003] For example, the existing plastic pipe protective film winding packaging machine includes a whole machine support, a clamping mechanism, a displacement mechanism, a rotating mechanism and a protective film supply mechanism arranged on the whole machine support. The clamping mechanism is used to support and clamp the product. The rotating mechanism is used to drive the product to rotate. The protective film supply mechanism can be a winding roller with a protective film wound thereon, which is used to output the protective film. The displacement mechanism is used to drive the product and the winding roller to move relative to each other, and the moving direction can be parallel to the length direction of the product. In actual work process, the product is fixed on the whole machine support by the clamping mechanism in advance, one free end of the protective film is attached to the surface of the product, and then the product is driven to rotate relative to the whole machine support by the rotating mechanism, such as rotation. At this time, the protective film will gradually separate from the winding roller under the pulling of the rotating product, which realizes the unwinding of the protective film from the winding roller. At the same time, the product and the winding roller can be driven to move relative to each other by the displacement mechanism, i.e. moving along the moving direction parallel to the length direction of the product. At this time, the protective film will be wound on the surface of the product along the length direction of the product, and finally the winding operation is completed.

[0004] For the related technology in the above, in the process of winding the protective film on the surface of the product, only the pulling of the product in rotation is used to realize the winding, which can easily cause the generation of bubbles at the attachment part of the protective film and the product surface, and the attachment is not tight enough, thereby affecting the winding and coating effect. SUMMARY

[0005] In order to optimize the attachment tightness of the protective film when it is wound on the surface of the product and optimize the winding and coating effect, the present application provides a spiral extrusion seamless winding production process and production equipment.

[0006] In the first aspect, the present application provides a spiral extrusion seamless winding production process, which adopts the following technical scheme:

[0007] A spiral extrusion seamless winding production process, comprising the following steps:

[0008] Drive the product to rotate at a specified speed, and transmit a specified width of material to the surface of the product;

[0009] The material is pressed on the product surface, and the pressing and drying of the material and the product are heated to make the material adhere and wrap around the product wall during the rotation of the product.

[0010] The output device is driven to move relative to the product, and the moving direction meets the requirement that the material is spirally wrapped around the product.

[0011] By using the above technical solution, the material is wrapped on the product surface in a pressing manner, thereby reducing the generation of air bubbles and improving the tightness of adhesion. In addition, if the material has viscosity, the heating and drying operation can quickly shape the adhesion part of the material and the product, thereby improving the wrapping efficiency and stability.

[0012] As a preferred, the method further comprises:

[0013] Whenever a specified length of material is wrapped around the product surface, the relative movement between the product and the material output device is paused, only the product is rotated, and after the product is rotated for a specified number of times, the relative movement between the product and the material output device is driven again; repeat the step until the thickness of the material wrapped on the product surface reaches the specified thickness requirement, and stop working.

[0014] By using the above technical solution, the relative movement is stopped, only the product is rotated, which makes the thickness of the material on the product surface different, forms a convex structure, and further achieves the effect of strengthening the local position strength of the product.

[0016] By adopting the above technical scheme, the product is connected to the rack by the rotating mechanism and is driven to rotate, the material is fed to the surface of the product by the feeding mechanism, and the material output from the output end of the feeding mechanism is attached and wound on the surface of the product in rotation. Since the shaping roller always abuts against the outermost surface of the product, the shaping roller will inevitably press the material on the outermost surface of the product during the winding of the material on the surface of the product, so as to smooth the surface of the product, reduce the air bubbles at the attachment position of the product and the material, and further strengthen the attachment tightness between the product and the material. In addition, the attachment position of the material and the product is heated by the heat-drying assembly, so as to quickly shape and further strengthen the contact tightness at the winding position of the product and the material.

[0018] By adopting the above technical scheme, the heating and drying of the surface of the product are realized by electrification and heat generation of the heating pipes, the heating temperature is automatically detected by the temperature control device, and the opening and closing of all the heating pipes are intelligently controlled to realize the automatic adjustment of the heating temperature and the heating range; the heat insulation energy gathering plate comprises a heat insulation layer and a heat gathering layer, so that the heat is concentrated on the surface of the product by the heat gathering layer, and the heat is insulated by the heat insulation layer to reduce the escape of heat and optimize the heating effect.

[0019] As a preferred, the rack is provided with an adjusting assembly, and the adjusting assembly is used for driving the heat insulation energy gathering plate to move towards or away from the product; the adjusting assembly comprises an adjusting frame, an adjusting gear, an adjusting rod and a rotation stopping piece; the adjusting frame is slidingly connected to the rack along the direction of approaching or moving away from the product, and the heat insulation energy gathering plate is arranged on the adjusting frame; the adjusting rod is rotatably connected to the rack, the adjusting gear is sleeved on the adjusting rod, and the adjusting gear is fixed relative to the adjusting rod; the rotation stopping piece is used for fixing the rotation position of the adjusting rod, and the side wall of the adjusting frame is provided with an adjusting tooth groove for engaging with the adjusting gear along the sliding direction thereof.

[0020] The adjusting assembly is used for adjusting the distance between the heat insulation energy gathering plate and the product, so that the heating position of the product is adaptively adjusted according to the size of the product, so that the distance between the heating pipe and the product can ensure the heating effect, and the situation that the heat escapes and the heating effect is poor due to the too large distance between the heating pipe and the product is avoided. Specifically, the adjusting rod is rotated to drive the adjusting gear to rotate, and then the adjusting frame engaged with the adjusting gear slides, so that the distance between the product and the heat insulation energy gathering plate on the adjusting frame is adjusted.

[0021] Preferably, the heat insulation energy gathering plate is arc-shaped, the rack is provided with a swing assembly, and the swing assembly is used to drive the heat insulation energy gathering plate to rotate around the product as the center.

The first air cylinder is connected to the butt joint rack at the driving end to drive the butt joint rack to slide.

[0022] By adopting the above technical scheme, the reciprocating sliding operation of the butt joint rack relative to the rack is realized through the extension and retraction movement of the piston rod of the first air cylinder, and then the butt joint gear rotates, and the heat insulation energy gathering plate rotates under the action of the butt joint gear slot and the butt joint gear, that is, the heat insulation energy gathering plate reciprocates around the product as the center of rotation, thereby expanding the heating and drying range of the product, accelerating the molding speed, and optimizing the heating and drying effect.

[0024] By adopting the above technical scheme, the gas is blown into the blowing pipe and the smoothing pipe through the gas supply member, and the gas is blown out of the blowing pipe and the smoothing pipe and acts on the outermost surface of the product. Since the blowing pipe, the setting roller and the smoothing pipe are sequentially arranged along the rotation direction of the product, the blowing pipe can first act on the surface of the product to remove dust and other impurities on the surface of the product, and then the subsequent material is pressed against the cleaned surface of the product by the setting roller.

[0030] By adopting the technical scheme, the detector detects the moving direction of the heat insulation energy-accumulating plate, and the second cylinder is opened or closed based on the rotating direction. When the heat insulation energy-accumulating plate moves downward, the second cylinder is controlled to be started, so that the rotating rod rotates under the pushing of the driving end of the second cylinder, and then the cleaning brush and the smoothing pad move towards the direction close to the product surface and abut against the product surface, thereby realizing the dust removal and smoothing operation on the product surface. Conversely, when the heat insulation energy-accumulating plate moves upward, the driving end of the second cylinder is controlled to be retracted, and the driving end of the second cylinder is separated from the pushing of the rotating rod.

DETAILED DESCRIPTION

[0041] The following will be explained in detail with reference to the accompanying drawings. Figures 1-6 The present application will be further explained in detail.

[0042] The embodiment of the present application discloses a spiral extrusion seamless winding production process. The process comprises the following steps:

[0043] S101, driving the product to rotate at a specified speed to convey a specified width of material to the surface of the product;

[0044] S102, pressing the material on the surface of the product, and heating and drying the pressed and fitted part of the material and the product, so that the material is fitted and wound on the peripheral wall of the product during the rotation of the product;

[0045] S103, driving the product to move relative to the output device of the material, and the moving direction satisfies: the material is spirally wound on the part to be wound on the product.

[0046] In the implementation, the product in the embodiment of the present application is specifically a storage tank, and the material can be specifically a protective film with adhesion. In actual production, after the storage tank is fixed, the storage tank is driven to rotate around the central axis, and then the free end of the material with a specified width is pressed against the outer surface of the storage tank. At this time, the material will be wound on the outer surface of the rotating storage tank, and at the same time, the material wound on the outer surface of the storage tank will be heated and dried to realize rapid shaping. In addition, the storage tank will also move along the axial direction during the rotation, so that the storage tank moves relative to the feeding end of the material, so that the material is spirally wound on the outside of the entire storage tank. The moving speed of the relative movement can be controlled according to the actual production needs, to realize seamless winding of the material pipe and adjustment of the overlapping width of the adjacent materials on the surface of the storage tank.

[0047] Preferably, the spiral extrusion seamless winding production process further comprises the following steps:

[0048] S104, whenever a specified length of material is wound on the product surface, the relative movement between the product and the material output device is paused, only the product rotation is maintained, and after the product rotates a specified number of times, the relative movement between the product and the material output device is re-driven; repeat this step until the thickness of the material wound on the product surface reaches the specified thickness requirement, stop working.

[0049] In implementation, whenever a specified length (such as 40-50 cm) of material is wound on the surface of the storage tank, the movement of the storage tank along its axis is stopped, while the rotation of the storage tank is still maintained, and after the storage tank rotates a predetermined number of times (such as one or more times), the relative movement between the storage tank and the material is re-driven again. The purpose of this step is to form a protruding structure on the surface of the storage tank at the local position, so as to play a role in structural reinforcement of the local position on the surface of the storage tank.

[0050] Correspondingly, the application also discloses a production device for the spiral extrusion seamless winding production process, and the specific structure is as follows:

[0051] Embodiment 1

[0052] Referring to Figure 1 A spiral extrusion seamless winding production device specifically comprises a rack 1, a rotating mechanism 2, a moving mechanism 3, a feeding mechanism 4 and a shaping mechanism 5 arranged on the rack 1. The rotating mechanism 2 is used for supporting a product and rotatingly connecting the product to the rack 1; the feeding mechanism 4 is used for feeding a specified width of material to the surface of the product; the moving mechanism 3 is used for driving the product to move relative to the feeding mechanism 4; and the shaping mechanism 5 is used for fixing the material on the surface of the product.

[0053] Referring to Figure 1 The rotating mechanism 2 comprises support rollers rotatingly connected to the upper surface of the rack 1 and a first motor used for driving the support rollers to rotate. There are four support rollers, two of which form a group, and the two groups are respectively arranged at the ends of the rack 1. The first motor is installed on the upper surface of the rack 1, and the driving end of the first motor is connected to the center of one of the support rollers. When one of the support rollers rotates, the product located on the support roller will rotate under the action of friction, and the rotating product will also drive the other support rollers to rotate under the action of friction. In the application, the rotating direction of the product is counterclockwise as shown by the arrow A in the figure.

[0054] Referring to Figure 1The moving mechanism 3 comprises rails welded to the ground, a screw rod rotationally connected to the rails, and a second motor for driving the screw rod to rotate. The rails are provided in two, and the rails are provided with grooves for inserting the lower end of the rack 1. The grooves are provided along the length direction of the rails. The screw rod is rotationally connected to the grooves, and the rack 1 is threadedly sleeved on the screw rod. The second motor is installed on the ground, and the driving end of the second motor is welded to the end of the screw rod.

[0055] With reference to Figure 1 and Figure 2 The feeding mechanism 4 can be an extruder for outputting a film with a specified thickness and a specified width. The output end of the feeding mechanism 4 is communicated with a discharge pipe 41. The discharge pipe 41 has a pipe opening with a diameter that is just enough for a single layer of material to pass through. The pipe opening of the discharge pipe 41 faces the product side wall. In another embodiment, a receiving roller can be rotationally connected to the pipe opening of the discharge pipe 41 for winding the material output by the extruder, thereby improving the efficiency of material feeding.

[0056] With reference to Figure 1 and Figure 2 The shaping mechanism 5 comprises a shaping roller 51 and a heat baking assembly 52. The discharge pipe 41, the shaping roller 51, and the heat baking assembly 52 are sequentially distributed along the rotation direction of the product. The shaping roller 51 is rotationally connected to the rack 1. A gap for the single layer of material to pass through is always reserved between the shaping roller 51 and the outermost surface of the product. A torsional spring is sleeved on the rotation connection shaft of the shaping roller 51 and the rack 1. The torsional spring is always in a deformed state. The material output from the discharge pipe 41 and adhered to the surface of the product will be moved to the shaping roller 51 under the driving of the rotating product and pass through the gap, so as to reduce the air bubbles at the adhered part between the material and the product surface by the pressing of the shaping roller 51, thereby improving the close adhesion.

[0057] With reference to Figure 1 and Figure 2 The heat baking assembly 52 comprises a heat insulation energy concentrating plate 521, a temperature control member 522, and a plurality of heating pipes 523. The heat insulation energy concentrating plate 521 is slidingly connected to the rack 1 along the direction close to or away from the product. The rack 1 is provided with an adjusting assembly 6 for driving the heat insulation energy concentrating plate 521 to slide. The adjusting assembly 6 specifically comprises an adjusting frame 61, an adjusting gear 62, an adjusting rod 63, and a rotation stopping member 64. The rotation stopping member 64 is a rod threadedly connected to the rack 1. The rotation stopping member 64 is inserted into the adjusting rod 63 and coaxially arranged with the adjusting rod 63. The rotation stopping member 64 is key-connected with the adjusting rod 63 to realize the synchronous rotation and relative sliding of the rotation stopping member 64 and the adjusting rod 63. The adjusting gear 62 is fixedly sleeved on the adjusting rod 63. The adjusting frame 61 is slidingly connected to the rack 1. The lower surface of the adjusting frame 61 is provided with an adjusting tooth groove 611 for engaging with the adjusting gear 62.

[0058] With reference to Figure 1 and Figure 2The heat insulation and energy gathering plate 521 is fixed on the adjusting frame 61, and is located at the periphery of the product. The heat insulation and energy gathering plate 521 is arc-shaped, and the arc radius of the heat insulation and energy gathering plate 521 forms a circular profile which is concentric with the rotation center of the product. The heat insulation and energy gathering plate 521 comprises a heat insulation layer 5211 and a heat gathering layer 5212. The heat gathering layer 5212 is located on the side of the heat insulation layer 5211 facing the product. The heat gathering layer 5212 is specifically made of metal material, and the heat insulation layer 5211 is specifically made of polymer material. The heating pipes 523 are located on the side of the heat gathering layer 5212 away from the heat insulation layer 5211, and all the heating pipes 523 are uniformly arranged along the arc direction of the heat gathering layer 5212.

[0059] With reference to Figure 1 and Figure 2 The heating pipe 523 can be a tubular structure with an embedded heating wire. The heating pipe 523 is electrically connected to an external power source, and is electrically connected to the temperature controller 522. The temperature controller 522 specifically comprises a temperature sensor 5221 and a controller 5222. The temperature sensor 5221 is used to detect the temperature data of the area between the heating pipe 523 and the product. The controller 5222 is used to obtain the above-mentioned temperature data, and to determine whether the temperature data meets the preset temperature range, so as to control the communication of each heating pipe 523 with the external power source, and to realize the adjustment of the heating temperature and the heating range.

[0060] The implementation principle of the spiral extrusion seamless winding production equipment disclosed in Embodiment 1 of the present application is as follows: the storage tank is placed on the support roller on the rack 1, and the material output by the feeding mechanism 4 is sequentially fitted to the surface of the product after passing through the gap between the pipe opening of the discharging pipe 41, the shaping roller 51 and the outermost surface of the storage tank, and then the first motor, the second motor and the hot drying assembly 52 are started. The first motor drives the storage tank to rotate, and the second motor drives the rack 1 loaded with the storage tank to slide along the axial direction of the storage tank, so that the material is spirally wound on the storage tank by the pulling of the storage tank. At the same time, the hot drying assembly 52 heats and dries the surface of the storage tank, so that the material is quickly shaped on the surface of the storage tank. When the specified length of material is wound on the storage tank, the second motor is paused, i.e. the relative movement between the storage tank and the feeding mechanism 4 is stopped, and only the rotation of the storage tank is maintained, so that the material is wound on the local position of the storage tank, and the local position of the storage tank is reinforced. After the storage tank rotates for a specified number of turns, the second motor is restarted to drive the storage tank to move relative to the feeding mechanism 4.

[0061] Embodiment 2

[0062] With reference to Figure 1The difference between the embodiment 2 of the present application and the embodiment 1 is that the heat-insulating energy-gathering plate 521 is arc-shaped, and the circular profile formed by the arc of the heat-insulating energy-gathering plate 521 is arranged at the same center as the rotation center of the product. The heat-insulating energy-gathering plate 521 is connected to the rack 1 in a sliding manner along the arc direction of the heat-insulating energy-gathering plate 521, and the side of the heat-insulating energy-gathering plate 521 away from the rack 1 is provided with a swing assembly 7, and the swing assembly 7 is used to drive the heat-insulating energy-gathering plate 521 to move in a circumferential direction with the central axis of the storage tank as the center. The swing assembly 7 specifically comprises a butt gear 71, a butt rack 72 and a first air cylinder 73. The butt gear 71 is rotatably connected to the rack 1. The butt rack 72 is slidably connected to the rack 1, and the butt rack 72 is engaged with the butt gear 71. The first air cylinder 73 is installed on the rack 1, and the driving end of the first air cylinder 73 is welded to the end wall of the butt rack 72. The side wall of the heat-insulating energy-gathering plate 521 is provided with a butt gear slot 5213 for engaging with the butt gear 71 along the arc direction of the heat-insulating energy-gathering plate 521.

[0063] Referring to Figure 2 and Figure 3 The top end of the heat-insulating energy-gathering plate 521 is provided with a smoothing pipe 74, and the bottom end of the heat-insulating energy-gathering plate 521 is provided with a blowing pipe 75. The blowing pipe 75 and the smoothing pipe 74 can be made of an elastically deformable material. The blowing pipe 75 and the smoothing pipe 74 are in communication with a gas supply member 77. The gas supply member 77 can be a gas suction pump. The gas inlet end of the gas supply member 77 is connected to a gas source through a pipeline. The gas outlet end of the gas supply member 77 is connected to a waste heat pipe 76. The waste heat pipe 76 penetrates through the side of the heat-insulating energy-gathering plate 521 close to the heating pipe 523 and extends to the periphery of the product. The blowing pipe 75 and the smoothing pipe 74 are in communication with the waste heat pipe 76. The pipe openings of the blowing pipe 75 and the smoothing pipe 74 away from the waste heat pipe 76 are both directed towards the surface of the product. The blowing pipe 75, the sizing roller 51 and the smoothing pipe 74 are sequentially arranged in the rotation direction of the storage tank.

[0064] The implementation principle of the spiral extrusion seamless winding production equipment disclosed in the embodiment 2 of the present application is as follows: in the process of winding the material around the peripheral wall of the storage tank, the gas supply member 77 is started to deliver high-pressure air into the blowing pipe 75 and the smoothing pipe 74. Since the blowing pipe 75 and the smoothing pipe 74 both pass through the side of the heat-insulating energy-gathering plate 521 close to the heating pipe 523, the delivered high-pressure air can absorb part of the preheating generated by the heating pipe 523. The high-pressure gas sprayed from the blowing pipe 75 can clean the surface of the storage tank to blow off dust and other impurities. The cleaned storage tank will be transferred to the sizing roller 51 and be attached to the material. Then the material will be sequentially pressed by the sizing roller 51, heated by the heating pipe 523 and moved to the smoothing pipe 74. The smoothing pipe 74 sprays high-pressure air with preheating to further smooth the outer surface of the storage tank and optimize the close-fitting degree of the storage tank and the material.

[0065] Embodiment 3

[0066] The difference between the embodiment 3 of the present application and the embodiment 1 is thatFigure 3 The heat insulation energy gathering plate 521 is arc-shaped, and a circular profile formed by the arc of the heat insulation energy gathering plate 521 is coaxial with the center of rotation of the product. The heat insulation energy gathering plate 521 is slidably connected to the rack 1 along the arc direction of the heat insulation energy gathering plate 521, and one side of the heat insulation energy gathering plate 521 away from the rack 1 is provided with an oscillating assembly 7 for driving the heat insulation energy gathering plate 521 to move circumferentially with the center axis of the storage tank as the center. The oscillating assembly 7 specifically includes a butt gear 71, a butt rack 72 and a first air cylinder 73. The butt gear 71 is rotatably connected to the rack 1, the butt rack 72 is slidably connected to the rack 1, and the butt rack 72 is engaged with the butt gear 71. The first air cylinder 73 is installed on the rack 1, and the driving end of the first air cylinder 73 is welded to the end wall of the butt rack 72. The side wall of the heat insulation energy gathering plate 521 is provided with a butt gear slot 5213 for engaging with the butt gear 71 along the arc direction of the heat insulation energy gathering plate 521.

[0067] Referring to Figure 4 and Figure 5 The rack 1 is provided with a driving assembly 8, and the driving assembly 8 includes a rotating rod 81, a second air cylinder 82, a reset member 83 and a detector 84. The top end and the bottom end of the heat insulation energy gathering plate 521 each correspond to one rotating rod 81, and the rotating rod 81 is rotatably connected to the end portion of the heat insulation energy gathering plate 521 and is arranged in a direction perpendicular to the width direction of the heat insulation energy gathering plate 521. The end of the rotating rod 81 located at the top of the heat insulation energy gathering plate 521 near the product is bonded with a smoothing pad 85 made of rubber, and the end of the rotating rod 81 located at the bottom of the heat insulation energy gathering plate 521 near the storage tank is bonded with a cleaning brush 86. Each rotating rod 81 corresponds to one second air cylinder 82 and one reset member 83. The second air cylinder 82 is installed on the side of the heat insulation energy gathering plate 521 away from the heating pipe 523, and the end of the rotating rod 81 away from the storage tank is located in the extension direction of the piston rod of the corresponding second air cylinder 82. The reset member 83 is specifically a torsion spring, and the reset member 83 is sleeved on the rotating connection shaft of the rotating rod 81 and the heat insulation energy gathering plate 521. When the piston rod of the second air cylinder 82 is elongated and pushes the end portion of the rotating rod 81, the rotating rod 81 rotates, and the reset member 83 is deformed.

[0068] Referring to Figure 5 and Figure 6 Figure 5 Figure 6The second cylinder 82 and the detector 84 are electrically connected to the controller 5222, and the detector 84 can be a distance sensor, which is installed on the rack 1 and located directly below the docking rack 72 to detect the distance data of the docking rack 72, and is electrically connected to the controller 5222, which is used to receive the distance data detected by the detector 84 and compare the changes of the distance data corresponding to adjacent receiving times. If the distance data corresponding to adjacent receiving times gradually increases, the second cylinder 82 is started to make the second cylinder 82 extend to push the rotating rod 81. Correspondingly, if the distance data corresponding to adjacent receiving times gradually decreases, the second cylinder 82 is closed to make the second cylinder 82 away from the rotating rod 81.

[0069] The implementation principle of the spiral extrusion seamless winding production equipment disclosed by Embodiment 3 of the present application is that: in the process of winding the material belt on the outer periphery of the storage tank, the first cylinder 73 is started to drive the heat-insulating energy-concentrating plate 521 to move back and forth around the central axis of the storage tank through the first cylinder 73, the docking gear 71 and the docking rack 72. During the back-and-forth movement, when the piston rod of the first cylinder 73 extends, the heat-insulating energy-concentrating plate 521 moves upwards, at this time, the heat-insulating energy-concentrating plate 521 moves in the same direction as the rotation direction of the storage tank, at this time, the distance data corresponding to adjacent receiving times detected by the detector 84 in real time gradually decreases, at this time, the second cylinder 82 is in a closed state, that is, the smoothing pad 85 and the cleaning brush 86 are not in contact with the surface of the storage tank.

[0070] When the piston rod of the first cylinder 73 retracts, the heat-insulating energy-concentrating plate 521 moves downwards, which is opposite to the rotation direction of the storage tank, at this time, the distance data corresponding to adjacent receiving times detected by the detector 84 in real time gradually increases, at this time, the controller 5222 starts the second cylinder 82 to push the rotating rod 81, the rotating rod 81 rotates and makes the flexible rubber pad and the cleaning brush 86 press against the surface of the storage tank, so as to realize the dust cleaning and smoothing treatment of the surface of the storage tank, and since the rotation direction of the storage tank is opposite to that of the smoothing pad 85 and the cleaning brush 86, the dust cleaning and smoothing effect of the surface of the storage tank can be further optimized. When the piston rod of the first cylinder 73 extends again, the piston rod of the second cylinder 82 retracts, at this time, the rotating rod 81 rotates back to the original position under the driving of the reset member 83, and the smoothing pad 85 and the cleaning brush 86 are away from the surface of the storage tank.

[0071] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
