Description

Technical Field

[0001] The invention relates to the technical field of stainless steel drying drum cleaning, in particular to an automatic cleaning device for a stainless steel drying drum. Background Art

[0002] In the processing of stainless steel drying drums, cleaning the inner and outer walls is a very important step. In the early processing, dirt, grease or other impurities may adhere to the surface of the stainless steel drying drum, and cleaning the inner and outer walls can effectively remove these impurities, ensuring that the product quality will not be affected by dirt during the processing; at the same time, cleaning can remove the corrosive media that may exist on the surface of the stainless steel, improve the corrosion resistance of the product, and extend its service life.

[0003] However, the existing cleaning method requires the stainless steel drying cylinder to be clamped and fixed. The general method is to clamp the two ends of the stainless steel drying cylinder synchronously. Since the stainless steel drying cylinder is long and heavy, the equipment required for clamping is long, and the clamping force must be large enough to perform the clamping operation. In addition, the existing clamping position is generally set to surface contact in order to increase the clamping force, so there is a large cleaning dead angle problem; during the cleaning process, the clamped stainless steel drying cylinder needs to be repeatedly placed in the water washing tank and the acid washing tank. During the repeated operations, the water washing tank and the acid washing tank are easily contaminated, which is not conducive to the subsequent cleaning operation of the stainless steel drying cylinder and affects the cleaning effect.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0030] See also Figure 1 , Figure 2 and Figure 3 , an automatic cleaning device for a stainless steel drying drum comprises: a workbench 1 symmetrically arranged in front and back, a conveying roller 11 connected by a conveyor belt is arranged between the workbench 1, the area between the workbench 1 is divided into a conveying part and a processing part, the conveying roller 11 located in the processing part is provided with a bottom bracket 2, a rotating support roller 3 is arranged above the bottom bracket 2, and the top of the rotating support roller 3 is rotatably connected to an external mechanical arm; an axial positioning external clamping mechanism 4 is arranged on the front and rear workbench 1 and located on the front and rear sides of the conveying roller 11 in the processing part, and is used for external clamping and limiting the stainless steel drying drum; an internal support assembly 5 is arranged on the rotating support roller 3, and multiple groups are arranged from top to bottom, which are used for internal support and limiting the stainless steel drying drum; a cleaning mechanism 6 is arranged on the rotating support roller 3, and is used for cleaning the inner and outer walls of the stainless steel drying drum.

[0031] Among them, the cleaning mechanism 6 includes a fixed bracket 61 fixedly connected to the rotating support roller 3, and two left and right arc plates 63 with corresponding positions are arranged in the fixed bracket 61 through a synchronous moving component 62, and support balls 64 are symmetrically arranged on the opposite sides of the two arc plates 63 through a fixed frame, and two clean water nozzles 65 are arranged above and below between the upper and lower support balls 64, and an acid water nozzle 66 is arranged between the upper and lower clean water nozzles 65. The opposite sides of the two arc plates 63 are symmetrically and detachably connected with scraper strips 67; the axial positioning external clamping mechanism 4 includes a pushing rod 46 for pushing the synchronous moving component 62, which is used to provide a driving force for the synchronous moving component 62 to move.

[0032] During operation, the finished stainless steel drying cylinder is placed vertically on the conveying roller 11 of the conveying part for conveying. When the stainless steel drying cylinder is conveyed to the processing part, the conveying roller 11 stops running, and the axis positioning external clamping mechanism 4 is started first to make a preliminary adjustment to the axis of the stainless steel drying cylinder entering the processing part. When the axis positioning external clamping mechanism 4 clamps the outer side of the stainless steel drying cylinder, the axis of the stainless steel drying cylinder coincides with the center position of the bottom bracket 2, and then the rotating support roller 3 is lowered to the inside of the stainless steel drying cylinder by the external mechanical arm. When the inner support assembly 5 at the lower end of the rotating support roller 3 enters the inside of the stainless steel drying cylinder, the axis positioning external clamping mechanism 4 is released to prevent the push rod 46 on the axis positioning external clamping mechanism 4 from causing the cleaning mechanism 6 to enter the stainless steel drying cylinder. When there is no obstruction, the rotating support roller 3 drives the inner support component 5 to completely enter the interior of the stainless steel drying cylinder. The cleaning mechanism 6 is located at the inner and outer wall positions of the upper end of the stainless steel drying cylinder, and the axial positioning external clamping mechanism 4 is started again to clamp the outer wall of the stainless steel drying cylinder. At the same time, the pushing rod 46 arranged on the axial positioning external clamping mechanism 4 pushes the synchronous moving component 62 until the arc plates 63 located on the inner and outer walls of the stainless steel drying cylinder are close to each other and close to the annular wall of the stainless steel drying cylinder. Finally, the rotating support roller 3 is driven by an external drive to rotate, thereby driving the two arc plates 63 to rotate around the axis of the rotating support roller 3 on the inner and outer walls of the stainless steel drying cylinder for cleaning. After each circle, the two arc plates 63 will synchronously drop a certain distance until the inner and outer walls of the stainless steel drying cylinder are completely cleaned.

[0033] When the cleaning mechanism 6 performs the cleaning work, the two arc plates 63 correspond to the inner and outer walls of the stainless steel drying cylinder respectively, and the supporting ball 64 contacts the inner and outer walls of the stainless steel drying cylinder. The clean water nozzle 65 and the acid water nozzle 66 on the arc plate 63 correspond to the cleaning liquid and the pickling liquid connected to the outside respectively. During the first downward movement of the arc plate 63, the upper and lower clean water nozzles 65 clean the inner and outer walls of the stainless steel drying cylinder with clean water. During the process of the arc plate 63 moving to the lowest end of the stainless steel drying cylinder and then returning to the top of the stainless steel drying cylinder, the acid water nozzle 66 pickles the inner and outer walls of the stainless steel drying cylinder. When the arc plate 63 moves downward again, the pickling process is repeated again. When the arc plate 63 moves upward for the last time, the clean water flushing is repeated again. That is, the arc plate 63 completes the cleaning operations of water washing, pickling, pickling, and water washing in the process of two upward and downward reciprocating movements. During the cleaning operation, the scraper bar 67 always plays a wiping role to make the cleaning effect better, and the scraper bar 67 adopts a detachable installation method and can be replaced at any time.

[0034] See also Figure 3 , Figure 7 , Fig. 9 and Fig.10The synchronous moving component 62 includes a rectangular placement groove 621 opened on the fixed bracket 61, and the inner wall of the rectangular placement groove 621 is slidably connected with a driving rack 622 on both the front and rear sides. The right side of the front driving rack 622 and the left side of the rear driving rack 622 are connected to the side walls corresponding to the rectangular placement groove 621 through a first spring 623. The middle of the front and rear driving racks 622 are meshed and connected with a connecting gear 624. The rotating shaft of the connecting gear 624 is rotatably connected to the U-shaped On the bracket 625, a sliding groove 626 is provided near the left side of the front driving rack 622 and near the right side of the rear driving rack 622. An L-shaped rod 627 is slidably connected to the sliding groove 626. The directions of the L-shaped rod 627 are relatively set. The bottom end of the L-shaped rod 627 is fixedly connected to an arc plate 63. A clamping column 628 is elastically connected to the sliding groove 626. The top ends of the front and rear L-shaped rods 627 are slidably connected to a linkage plate 629. An intermittent moving component 7 is also provided on the U-shaped bracket 625.

[0035] The synchronous moving component 62 can drive the arc-shaped plates 63 on the inner and outer walls of the stainless steel drying cylinder to move closer or farther away synchronously. The specific working process is as follows: when the pushing rod 46 is pushed to the left side of the arc-shaped plate 63 located on the outer side of the stainless steel drying cylinder, the driving rack 622 located on the front side will move to the right, at this time driving the connecting gear 624 to engage the driving rack 622 on the rear side to move to the left, that is, the L-shaped rod 627 located on the front driving rack 622 drives the arc-shaped plate 63 on the outer side of the stainless steel drying cylinder to move close to the outer wall of the stainless steel drying cylinder, and the L-shaped rod 627 located on the rear driving rack 622 drives the arc-shaped plate 63 inside the stainless steel drying cylinder to move close to the inner wall of the stainless steel drying cylinder. At this time, the front and rear first springs 623 are both in a compressed state, and the clamping column 628 located in the sliding groove 626 is always pressed against the L-shaped rod 627 to prevent the L-shaped rod 627 from moving downward due to gravity.

[0036] See also Figure 1 and Figure 8 , and also includes a one-way movable limit assembly 8 arranged on one of the driving racks 622. The one-way movable limit assembly 8 includes a beveled rack 81 fixedly connected to the side of the upper end of the driving rack 622 away from the gear teeth. A control ratchet 82 is engaged with the beveled rack 81, and the control ratchet 82 is rotatably connected to a fixed column fixedly connected to the upper end of the fixed bracket 61 through a torsion spring.

[0037] The one-way movable limit assembly 8 is set to allow the driving rack 622 to move only in one direction. The specific working process is as follows: when the driving rack 622 located on the front side moves to the right, the squeezed first spring 623 has the stored force to push the driving rack 622 to the left, but under the action of the control ratchet 82 and the bevel rack 81, the driving rack 622 can only move to the right and cannot move to the left, so as to ensure the stability of the position of the driving rack 622 after movement. Correspondingly, the driving rack 622 on the rear side will also remain in the position after the movement.

[0038] See also Figure 3 and Figure 7 The intermittent moving component 7 includes a limiting rod 71 fixedly connected to the upper end of the U-shaped bracket 625, the top of the limiting rod 71 slides through the linkage plate 629, one side of the limiting rod 71 is rotatably connected to an incomplete gear 72, the rotating shaft of the incomplete gear 72 passes through the limiting rod 71 and is fixedly connected to a forward and reverse motor 73 connected to the upper end of the U-shaped bracket 625 through a bracket, and a vertical rack 74 is provided at the rear end of the L-shaped rod 627 located on the front side. The length of the teeth on the incomplete gear 72 is longer than the length of the teeth on the vertical rack 74, and the incomplete gear 72 is meshed with the vertical rack 74.

[0039] The intermittent moving component 7 can drive the L-shaped rod 627 located inside and outside the stainless steel drying cylinder to move up and down synchronously. Since the length of the gear teeth on the incomplete gear 72 is longer than the length of the gear teeth on the vertical rack 74, when the driving rack 622 drives the L-shaped rod 627 to move synchronously, the vertical rack 74 is always in a meshing state with the incomplete gear 72. The specific working process of the up and down movement of the L-shaped rod 627 is as follows: when the arc plate 63 cleans one circle along the stainless steel drying cylinder, the forward and reverse motor 73 drives the incomplete gear 72 to rotate. When the gear teeth on the incomplete gear 72 are meshed with the vertical rack 74, the vertical rack 74 is driven to move downward. The vertical rack 74 synchronously drives the corresponding L-shaped rod 627 to move downward. Since the top ends of the L-shaped rods 627 are connected to a linkage plate 629, the linkage plate 629 will synchronously drive the other L-shaped rod 627 to descend synchronously. The linkage plate 629 moves on the limit rod 71. The limit rod 71 plays a limiting role, which can ensure that the two L-shaped rods 627 remain synchronized during the movement.

[0040] See also Figure 5 The bottom bracket 2 is fixedly connected between the front and rear symmetrical workbenches 1 through a connecting support 21. The length of the conveying roller 11 located at the bottom bracket 2 is shorter than that of the conveying roller 11 at other positions, and the conveying roller 11 located at the corresponding position of the bottom bracket 2 is rotatably connected to the bottom bracket 2 at the opposite end to the bottom bracket 2. A round groove seat 22 is fixedly connected in the middle of the bottom bracket 2.

[0041] The setting of the bottom bracket 2 supports the rotating support roller 3. The rotating support roller 3 is relatively long, and during the cleaning operation, the rotating support roller 3 will drive the inner support assembly 5 and the cleaning mechanism 6 to rotate. The rotating support roller 3 is placed on the bottom bracket 2. The bottom bracket 2 can maintain the axial stability of the rotating support roller 3 while playing a supporting role, and the setting of the conveying roller 11 at the corresponding position of the bottom bracket 2 will not affect the conveying of the stainless steel drying cylinder after the cleaning operation is completed.

[0042] See also Figure 1 , Figure 2 and Figure 3 The axis positioning external clamping mechanism 4 includes a rotating connecting column 41 rotatably connected to the front and rear workbenches 1, and the upper and lower ends of the rotating connecting column 41 extend to the upper and lower ends of the workbench 1. The part of the rotating connecting column 41 located above the workbench 1 is fixedly connected to an L-shaped frame 42, and the other end of the L-shaped frame 42 is fixedly connected to an arc-shaped transition connecting plate 43, and the inner ring surface of the arc-shaped transition connecting plate 43 is elastically connected to a pressing member 44. The upper end of the arc-shaped transition connecting plate 43 located at the rear side is fixedly connected to a push rod 46. A driving assembly 45 is provided on one of the rotating connecting columns 41, and the driving assembly 45 is located below the workbench 1. The driving assembly 45 includes a synchronous belt 451 rotatably connected between the front and rear rotating connecting columns 41, a rotating gear 452 is fixedly connected to one of the rotating connecting columns 41, and a moving rack 453 is meshed and connected to one side of the rotating gear 452, and the moving rack 453 is slidably connected to the workbench 1 on the corresponding side through a moving bracket, and a second electric slider is fixedly connected to the moving bracket.

[0043] The axial positioning outer clamping mechanism 4 is used to clamp and limit the outer side of the stainless steel drying cylinder. The specific working process is as follows: start the second electric slider to drive the moving rack 453 on the moving bracket to move, and the moving rack 453 engages with the rotating gear 452 to rotate. The rotating gear 452 will drive one of the rotating connecting columns 41 to rotate, and the other rotating connecting column 41 will rotate at the same time under the action of the synchronous belt 451. The rotating connecting column 41 will drive the arc-shaped transition connecting plate 43 on the L-shaped frame 42 to rotate 90 degrees around the corresponding rotating connecting column 41. The arc-shaped transition connecting plates 43 on both sides will be close to the left and right outer walls of the stainless steel drying cylinder respectively, and the pressing piece 44 will be pressed against the outer wall of the stainless steel drying cylinder respectively. The pressing piece 44 can be a spherical structure connected by an elastic rubber rod, and it has multi-point contact with the outer wall of the stainless steel drying cylinder. When performing cleaning operations, the cleaning liquid can still flow through the positions between multiple pressing pieces 44 to reduce the cleaning obstruction area.

[0044] See also Figure 3 and Figure 6One end of the arc-shaped transition connecting plate 43 is provided with a receiving groove 431, and the receiving groove 431 is connected to a arc-shaped docking rod 432 through a first electric slider. The other end of the arc-shaped transition connecting plate 43 is provided with an arc-shaped limiting groove 433 corresponding to the arc-shaped docking rod 432, and the position of the arc-shaped docking rod 432 on one arc-shaped transition connecting plate 43 is set corresponding to the arc-shaped limiting groove 433 on the other arc-shaped transition connecting plate 43.

[0045] During operation, when the arc-shaped transition connecting plates 43 on both sides abut against the outer wall of the stainless steel drying cylinder, the first electric slider is started to drive the arc-shaped docking rod 432 to move into the arc-shaped limiting groove 433 on the opposite side, so that the left and right arc-shaped transition connecting plates 43 form a complete annular structure to enhance the stability of the stainless steel drying cylinder in subsequent cleaning operations.

[0046] See also Figure 3 and Figure 4 The inner support assembly 5 includes a fan-shaped plate 51 fixedly connected by multiple fixing rods. The fan-shaped plate 51 and the arc-shaped plate 63 placed inside the stainless steel drying cylinder form a circular structure. Multiple spring telescopic tubes 52 are evenly arranged on the outer arc edge of the fan-shaped plate 51, and a movable rolling ball 53 is rotatably connected to the spring telescopic tube 52.

[0047] In order to enhance the stability of the inner side of the stainless steel drying cylinder, while the supporting roller 3 is rotating, multiple groups of inner support components 5 will be synchronously driven to rotate inside the stainless steel drying cylinder. Since the cleaning mechanism 6 and the inner support components 5 are always rotating synchronously, the arc plate 63 is always located at the notch of the fan plate 51. When the arc plate 63 descends, the inner support component 5 will not hinder the descent of the arc plate 63. The movable ball 53 is provided to facilitate rotation. The spring telescopic tube 52 is provided to enable the movable ball 53 to have a certain extrusion force on the inner wall of the stainless steel drying cylinder, thereby increasing the stability of the inner support.
