DETAILED DESCRIPTION

[0026] 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 described embodiments 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.

[0027] During the curling process of the existing curling device, the roller and the curling wheel are in direct contact, and the friction between the two is relatively large, which not only accelerates the wear of the curling wheel, but also easily causes uneven or unsmooth curling effects of the roller during the curling process, such as scratches, dents and other defects, ultimately affecting the quality and appearance of the roller.

[0028] To solve the defects of the above-mentioned curling device during the curling process, please refer to Figure 1-Figure 7The present invention provides a curling device for washing machine drum processing, which can reduce the friction between the drum and the curling wheel, making the curling process smoother, helping the drum to form a more uniform edge during curling, reducing the occurrence of scratches, dents and other defects, and cooling the drum curling area after curling is completed to prevent the drum temperature from being too high and scalding the staff. The curling device is based on a processing table 2 installed on a base 1 for detachably positioning a roller, and a curling mechanism 3 for curling the roller. The processing table 2 can drive the roller to rise and fall, as well as to stretch the roller and drive the roller to rotate. The curling mechanism 3 is provided with a curling wheel that can be raised and lowered and retracted. The processing table 2 and the curling mechanism 3 are both prior arts, and their component composition and working principle are not described in detail herein. The roller can be curled on the processing table 2 in cooperation with the curling wheel; a bracket 4 is fixedly installed on one side of the top of the base 1, and a vertical plate 5 is fixedly installed on the front end of the bracket 4. A wetting and cooling component 6 is provided on the vertical plate 5 for lubricating and cooling the roller when the curling mechanism 3 curls the roller. The wetting and cooling component 6 can not only lubricate the roller during the roller curling process, improve the smoothness of the curling process, and reduce the deformation resistance of the roller, but also quickly cool down the curling part of the roller to avoid high temperature scalding caused by high-speed friction between the roller and the curling wheel, and facilitate the unloading operation. In order to achieve the above-mentioned effect of the wetting and cooling component 6, a rotating installation is provided. The rotating shaft 61 is fixedly connected to the front end of the rotating shaft 61 with a flap 62. The top and bottom of the flap 62 are respectively installed with cooling cotton 63 and lubricating cotton 64. The cooling cotton 63 is adsorbed with coolant, and the lubricating cotton 64 is adsorbed with lubricating oil. The cooling cotton 63 and the lubricating cotton 64 are both arranged in a U shape. When curling, the lubricating cotton 64 faces downward, and the roller is driven up by the processing table 2 so that the edge of the roller is stuck in the lubricating cotton 64. During the rotation of the roller, the lubricating cotton 64 can wipe the roller, and the lubricating oil is applied to the edge of the roller. The edge can achieve the effect of lubricating the curling edge, and the cooling is the same. The ends of the cooling cotton 63 and the lubricating cotton 64 are both provided with transition surfaces 68. The setting of the transition surface 68 can make it more convenient to insert the edge of the drum. The inner wall of the cooling cotton 63 is provided with a flanging groove 69, and the flanging groove 69 is arranged in an arc shape. After the drum is curled, the curled part of the drum will be turned outward, and the setting of the flanging groove 69 can be inserted into the curled part of the drum, so that the cooling cotton 63 can fit tightly with the curled and uncurled parts of the drum, thereby optimizing the application effect of the coolant.

[0029] As the curling process proceeds, the lubricating oil on the lubricating cotton 64 will gradually be smeared on the roller, while the lubricating oil on the contact surface between the lubricating cotton 64 and the roller will gradually become less, resulting in less lubricating oil attached to the roller as the curling process progresses, affecting the lubrication effect of the latter half. The same problem also exists when applying coolant subsequently. In order to solve this technical problem, both sides of the cooling cotton 63 and the lubricating cotton 64 are fixedly installed with squeeze plates 65, and a slider 67 is fixedly connected between the two squeeze plates 65 on the same side. The slider 67 is slidably installed inside the flap 62, and the flap 62 is also provided with a An extrusion member 66 is provided for driving two groups of extrusion plates 65 to approach each other and gradually squeeze the cooling cotton 63 and the lubricating cotton 64. The extrusion member 66 is driven during curling, and the extrusion member 66 drives the two groups of extrusion plates 65 to gradually approach each other, so that the two groups of extrusion plates 65 gradually squeeze the cooling cotton 63 and the lubricating cotton 64 respectively. As the curling work proceeds, the lubricating oil absorbed in the lubricating cotton 64 is slowly squeezed out, which can ensure the continuity and uniformity of the lubricating oil applied to the roller, and avoid the situation of insufficient lubrication in the later stage of curling. After the curling is completed, the roller is cooled by applying coolant through the cooling cotton 63 in the same way.

[0030] In order to achieve the gradual squeezing effect of the squeezing plate 65 on the cooling cotton 63 and the lubricating cotton 64, refer to Figure 5-Figure 7 As shown, a push-pull rod 661 is provided which is slidably inserted into the interior of the flap 62, one of the sliders 67 is slidably sleeved on the outside of the push-pull rod 661, and the other slider 67 is fixedly connected to the rear end of the push-pull rod 661. Indirect shafts 662 are slidably installed on both sides of the interior of the flap 62. A groove for the indirect shaft 662 to slide left and right is provided on the inner bottom wall of the flap 62. Two connecting rods 663 are rotatably sleeved on the outside of the indirect shaft 662. The ends of the two connecting rods 663 are respectively hinged on the two sliders 67. A connecting rod 664 is fixedly connected to one end of the push-pull rod 661 located on the outside of the flap 62. An electric push rod 664 acting on the connecting rod 664 is installed on the flap 62. 65, the driving electric push rod 665 can drive the push-pull rod 661 to slide forward through the connecting rod 664, and the push-pull rod 661 pulls one of the sliders 67 to slide, and the slider 67 drives one of the groups of connecting rods 663 to rotate. The rotation of the connecting rod 663 drives the two indirect shafts 662 to move away from each other, and the indirect shaft 662 drives the other group of connecting rods 663 to rotate, which can drive the other group of sliders 67 to slide backward. The sliding of the two groups of sliders 67 drives the two groups of squeezing plates 65 to approach each other, and the squeezing plates 65 squeeze the cooling cotton 63 and the lubricating cotton 64 to gradually deform them, so that the coolant and lubricating oil in the cooling cotton 63 and the lubricating cotton 64 can be gradually squeezed out and smeared on the roller.

[0031] After each use of the edge-running cooling component 6, it is necessary to add coolant and lubricating oil to the cooling cotton 63 and the lubricating cotton 64 to ensure that the edge-running cooling component 6 can cool and lubricate the next roller. In order to facilitate the replenishment work, a slide 10 located above the edge-running cooling component 6 is opened on the vertical plate 5. The interior of the slide 10 is slidably connected to a hanger 11. Two liquid supply barrels 12 are installed side by side at the front end of the hanger 11. Lubricating oil is added to the interior of one of the liquid supply barrels 12, and coolant is added to the interior of the other liquid supply barrel 12. The coolant can be set to ice water, and ice cubes can be directly added to the liquid supply barrel 12. As the curling work proceeds, the ice cubes can automatically melt into ice water, which is convenient for supplying the cooling cotton 63.

[0032] In order to improve the uniformity of the distribution of the coolant and lubricating oil in the cooling cotton 63 and the lubricating cotton 64, a liquid outlet pipe 13 is installed at the lower end of the liquid supply barrel 12. The liquid outlet pipe 13 is provided with three liquid outlets. The height of the liquid outlet in the middle is lower than the height of the liquid outlets on both sides, which can avoid the coolant and lubricating oil from being concentrated at a certain position of the cooling cotton 63 and the lubricating cotton 64.

[0033] In order to switch the positions of the cooling cotton 63 and the lubricating cotton 64, the rotating shaft 61 is required to drive the flap 62 to flip. Therefore, a servo motor 8 is fixedly installed on the top of the bracket 4 for driving the rotating shaft 61 to rotate one hundred and eighty degrees. The output end of the servo motor 8 is fixedly connected to the center of the rotating shaft 61. When curling, the cooling cotton 63 faces upward and the lubricating cotton 64 faces downward. After curling, the servo motor 8 is driven to drive the flap 62 to flip, so that the lubricating cotton 64 faces upward and the cooling cotton 63 faces downward.

[0034] Since the cooling cotton 63 and the lubricating cotton 64 need to be flipped back and forth, it is inconvenient to supply the coolant and lubricating oil in the two liquid supply barrels 12 to the cooling cotton 63 and the lubricating cotton 64 respectively. In order to solve this technical problem, a transmission mechanism 9 is provided between the rotating shaft 61 and the hanging bracket 11, which drives the hanging bracket 11 to slide along the slide groove 10 as the rotating shaft 61 rotates. The transmission mechanism 9 includes a gear 91 rotatably installed on the back of the vertical plate 5. The center of the gear 91 and the rear end of the rotating shaft 61 are fixedly connected with a synchronous wheel 92. A synchronous belt 93 is installed between the two synchronous wheels 92. A rack 94 is fixedly connected to the bottom of the hanging bracket 11. The rack 94 is meshed with the gear 91, and the length of the rack 94 is half the circumference of the gear 91. Figure 4The cooling cotton 63 is facing upward, and the liquid supply barrel 12 with coolant added is directly above the cooling cotton 63. An electromagnetic valve is installed on the liquid outlet pipe 13. Driving the electromagnetic valve can control the opening and closing of the liquid outlet pipe 13. When the liquid outlet pipe 13 is opened, coolant can be added to the cooling cotton 63. When the winding is completed and the cooling work is carried out, the servo motor 8 is driven to drive the rotating shaft 61 to rotate half a circle. At this time, the lubricating cotton 64 is turned upward. At the same time, the rotating shaft 61 drives the gear 91 to rotate a semicircle through the synchronous wheel 92 and the synchronous belt 93. The rotation of the gear 91 drives the hanger 11 to slide. The hanger 11 drives the two liquid supply barrels 12 to move synchronously. The liquid supply barrel 12 with coolant added is removed from the cooling cotton 63, and the liquid supply barrel 12 with lubricating oil can just move to the top of the lubricating cotton 64, and then the lubricating oil can be added to the lubricating cotton 64.

[0035] In order to prevent the edge smoothing and cooling component 6 from hindering the loading and unloading of the roller, a hydraulic cylinder 7 is installed on the base 1 to drive the processing table 2 to move forward and backward. When loading and unloading, the hydraulic cylinder 7 can drive the processing table 2 to move to be staggered with the edge smoothing and cooling component 6, so as to facilitate the roller to be placed on the processing table 2.

[0036] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
