Description

Technical Field

[0001] This utility model relates to the technical field of automatic cleaning equipment, specifically to an online cleaning device. Background Technology

[0002] During the wire drawing process, lubricating oil or grease is usually used to reduce friction. If residue is not removed, it may affect the adhesion of subsequent processing, leading to plating peeling or uneven coating. Adhered dust and other contaminants will also affect subsequent processing. Therefore, metal wires need to be cleaned before processes such as enameling, electroplating, or coating to provide a foundation for the quality of subsequent processing. If there are still contaminants on the metal wires, it will affect the quality of the product after enameling and will also affect the insulation of the enameled wire. Common applications of enameled wire include motor enameling wire.

[0003] Currently, there are various methods for cleaning metal wires. After cleaning, the metal wire can be guided by guide wheels and then wound up before entering the next process, or it can be guided by guide wheels and directly enter the next process. Therefore, the cleanliness of the guide wheels will also affect the metal wire. If there are adhering substances on the guide wheels, these substances will be transferred to the metal wire when it passes through the guide wheels. Thus, the cleanliness of the guide wheels will also affect the quality of subsequent processing of the metal wire. Therefore, it is necessary to design an online cleaning device.

[0038] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0039] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0040] like Figure 1-7 As shown, an online cleaning device includes at least one set of guide wheels 1 and at least one set of guide wheel wiping units 2 that match the corresponding guide wheels 1. The guide wheel wiping unit 2 includes a mounting plate 3, a cleaning block 4 that is slidably mounted on the mounting plate 3, a cloth roll 5 that slides from the lower surface of the cleaning block 4 after the end of the cleaning strip is pulled out, a winding and unwinding mechanism that matches the cloth roll 5, and an auxiliary agent delivery mechanism mounted on the mounting plate 3.

[0041] The top of the cleaning block 4 is provided with a drain channel 6, the outlet end of the auxiliary agent conveying mechanism is located directly above the upper end of the drain channel 6, and the lower end of the drain channel 6 is blocked by the cleaning strip pulled out by the cloth roll 5.

[0042] In the above technical solution, the mounting plate 3 is also equipped with an aviation connector 35 to facilitate multi-device linkage control of the multi-guide wheel wiping unit 2;

[0043] After cleaning, the metal wire needs to pass through guide wheel 1 to control its direction. Guide wheel wiping unit 2 can wipe guide wheel 1 in real time to ensure its cleanliness and prevent dust, impurities, and other contaminants from being transferred to the metal wire. Contaminants on the metal wire can affect subsequent processing, such as electroplating, coating, and enameling. For example, during enameling, the deposits on the metal wire can affect the quality of the enameling and the insulation of the enameled wire. Therefore, real-time cleaning of guide wheel 1 is beneficial to improving the quality of the enameled wire after processing and improving its insulation and other properties.

[0044] The additive can be delivered to the drain channel 6 through the additive delivery liquid. The cleaning strip that can wet the cloth roll 5 flows out through the lower end of the drain channel 6. If the additive is a cleaning agent, the wetted cleaning strip can further improve the cleaning effect and further improve the quality and insulation of the enameled wire.

[0045] After the cleaning strip of the unwound cloth roll 5 contacts the guide wheel 1 for a period of time, the unwinding mechanism drives the cloth roll 5 to unwind one end and wind up the other end, so that the clean cleaning strip contacts the guide wheel 1. This eliminates the need for frequent machine stops to replace the cleaning strip. By cooperating with the unwinding mechanism, the frequency of machine stops for replacement can be reduced, and the guide wheel 1 can be kept clean in real time, thereby improving the quality of subsequent metal wire processing, such as improving the insulation of the enameled wire.

[0046] The cleaning block 4 can continuously clean the guide wheel 1 by moving downwards, or it can move up and down intermittently to clean the guide wheel 1. This can be adjusted according to specific usage requirements.

[0047] In a preferred embodiment of the present invention, the additive delivery mechanism includes an additive box 7 mounted on the mounting plate 3 and located above the cleaning pressure block 4, and a throttle valve 8 fixedly mounted on the cleaning pressure block 4 with its outlet located directly above the upper end of the drain channel 6. The inlet end of the throttle valve 8 is connected to the outlet end at the bottom of the additive box 7 via a connecting pipe 9.

[0048] In the above technical solution, the conveying speed of the additive can be controlled by the throttle valve 8, thereby controlling the liquid content on the cleaning strip and avoiding too much or too little additive on the cleaning strip. The additive tank 7 is located above the throttle valve 8, and the additive can flow to the throttle valve 8 due to gravity. The flow of the additive does not require electricity, thus achieving an energy-saving effect.

[0049] In a preferred embodiment of this utility model, a valve 10 for controlling the opening and closing of the connecting pipe 9 is provided in the middle of the connecting pipe 9.

[0050] In the above technical solution, valve 10 can control the opening and closing of connecting pipe 9. In conjunction with throttle valve 8, it can more reasonably control the conveying speed and conveying amount of additives, so that the additives can be used in a reasonable manner.

[0051] In a preferred embodiment of this utility model, the take-up and unwinding mechanism includes a motor 11 mounted on a mounting plate 3, a horizontal take-up shaft 12 rotatably mounted on the mounting plate 3 and connected at one end to the output shaft of the motor 11, a fixed shaft 13 fixedly mounted on the mounting plate 3 and arranged parallel to the take-up shaft 12, and a drive push rod 14 mounted on the mounting plate 3 and connected at one end to the cleaning pressure block 4. The cloth roll 5 is mounted on the fixed shaft 13 through an elastic mounting mechanism.

[0052] In the above technical solution, the drive push rod 14 can drive the cleaning pressure block 4 to move downward. When changing the cloth roll 5, the drive push rod 14 will drive the cleaning pressure block 4 to move upward. The elastic mounting mechanism is removed, and the center of the new cloth roll 5 is fitted onto the fixed shaft 13. The elastic mounting mechanism can apply resistance to the unwinding of the cloth roll 5. The motor 11 will drive the winding shaft 12 to rotate, thereby pulling the end of the cloth roll 5 and driving the body of the cloth roll 5 to be passively unwound.

[0053] The take-up shaft may have a notch for inserting the end of the cloth roll 5, and a fixing bolt for fixing the end of the cloth roll 5 is provided at the notch.

[0054] In a preferred embodiment of the present invention, the elastic mounting mechanism includes a pair of clamping discs 15 that can be sleeved on the fixed shaft 13 for clamping the cloth roll 5, a nut 16 threadedly mounted on the end of the fixed shaft 13 away from the mounting plate 3, and a spring 17 sleeved on the fixed shaft 13.

[0055] The fixed shaft 13 has a protruding flange. The clamp 15, which is away from the nut 16, is in contact with the flange. The two ends of the spring 17 are in contact with the nut 16 and the clamp 15 near the nut 16, respectively.

[0056] In the above technical solution, by loosening or tightening the nut 16, the compression degree of the spring 17 can be adjusted, thereby adjusting the pressure applied by the spring 17 to the corresponding clamp 15, and thus adjusting the unwinding resistance applied to the cloth roll 5. The operation is simple and convenient.

[0057] When replacing the cloth roll 5, loosen and remove the nut 16, then remove the spring 17 and the corresponding clamp 15, clamp the new cloth roll 5 with a pair of clamps 15 and put it on the fixed shaft 13, then put the spring 17 on the fixed shaft 13, and tighten the nut 16 to compress the spring 17.

[0058] In a preferred embodiment of the present invention, the center of the guide wheel 1 is connected to the mounting shaft 18 via a bearing, and the mounting plate 3 is mounted on the mounting shaft 18 via a height adjustment mechanism;

[0059] The height adjustment mechanism includes a vertical mounting arm 19 fixedly mounted on the mounting plate 3, a strip arm 20 through which at least one vertical strip mounting groove is provided, a plurality of first mounting bolts 21 threadedly connected to the mounting arm 19 through the corresponding strip mounting groove, and a pair of clamps 22 mounted on the lower end of the strip arm 20 for holding the mounting shaft 18.

[0060] One of the clamps 22 is connected to the other clamp 22 by a plurality of second mounting bolts.

[0061] In the above technical solutions, the cleaning equipment usually has at least one mounting base 36, and the mounting shaft 18 is fixedly mounted on the mounting base 36. Other auxiliary equipment can also be mounted on the mounting base 36.

[0062] The height adjustment mechanism allows the guide wheel wiping unit 2 to be adjusted according to the diameter of the guide wheel 1 to adapt to guide wheels 1 of different specifications, making it highly practical. By loosening several first mounting bolts 21, the strip arm 20 and the mounting arm 19 can slide relative to each other. Adjusting the height of the mounting plate 3 and then tightening the first mounting bolts 21 so that their heads are firmly pressed against the strip arm 20 can fix the strip arm 20 and the mounting arm 19 in place.

[0063] In a preferred embodiment of the present invention, a cleaning unit is further included, the cleaning unit including a box 24 having at least one liquid storage chamber 23 inside, at least one spraying mechanism matching the liquid storage chamber 23, and a water blower assembled at the discharge end of the box 24.

[0064] The upper part of the wall of the liquid storage chamber 23 is provided with a feed port. The spraying mechanism includes a filter component 25, a water pump 26 whose water inlet end is connected to the liquid storage chamber 23, a hollow annular component 28 connected to the filter component 25 through a rigid connecting pipe 27, and at least one nozzle 29 assembled on the annular component 28.

[0065] The outlet of the water pump 26 is connected to the filter component 25, and the annular component 28 is located inside the liquid storage chamber 23.

[0066] The top of the box 24 is an openable cover.

[0067] In the above technical solution, the metal wire enters from one feed port on the wall of the liquid storage chamber 23 and exits from the other feed port. When the metal wire is inside the liquid storage chamber 23, the water pump 26 will draw the cleaning liquid inside the liquid storage chamber 23. After being filtered by the filter component 25, it enters the annular component 28 and then impacts the metal wire through the nozzle 29 to clean the metal wire.

[0068] The filter element 25 can filter the cleaning fluid. The filter element 25 generally includes a cylindrical shell and a filter element disposed inside the cylindrical shell. The top of the cylindrical shell is an openable cover, which facilitates the replacement of the filter element inside.

[0069] When there are multiple liquid storage chambers 23 on the housing 24, different liquids or additives can be filled into the multiple liquid storage chambers 23 respectively;

[0070] When used alone, the cleaning unit can also clean rod-shaped or tubular objects such as bellows.

[0071] The cover plate not only facilitates cleaning of the inside of the liquid storage chamber 23, but also facilitates manual operation by passing the metal wire through the feed port and the annular part 28 for manual feeding.

[0072] In a preferred embodiment of the present invention, the cleaning block (4) is equipped with a mounting bracket, and the mounting bracket is equipped with a pair of clamping mechanisms located on both sides of the cleaning block (4).

[0073] The clamping mechanism includes a pair of clamping rollers (37) for clamping the cleaning strip pulled out by the cloth roll (5) and tension springs (38) connected at both ends to the ends of the pair of clamping rollers (37), and at least one clamping roller (37) is slidably mounted on the mounting bracket.

[0074] In the above technical solution, a pair of clamping rollers 37 can clamp the cleaning strip pulled out by the cloth roll 5 under the action of the tension spring 38. When the cleaning pressure block 4 moves upward, the pair of clamping rollers 37 can clamp the cleaning strip, so that the cleaning strip is in contact with the cleaning pressure block 4, and the cleaning strip is prevented from loosening when the cleaning pressure block 4 moves upward. Under the tension of the tension spring 38, the pair of clamping rollers 37 clamp the cleaning strip, so when the take-up shaft 12 is normally winding, the cleaning strip can also move between the pair of clamping rollers 38.

[0075] Common small clamping rollers 37 typically consist of a hollow rubber sleeve and a bolt passing through the rubber. The rubber sleeve can also rotate, which can further reduce the resistance when the cleaning strip is pulled out and reduce the probability of the cloth roll 5 breaking.

[0076] In a preferred embodiment of this utility model, the take-up and unwinding mechanism further includes several tension rollers 30 arranged parallel to the take-up shaft 12 and rotatably mounted on the mounting plate 3. The cleaning strip after being pulled by the cloth roll 5 passes through several tension rollers 30 and is wound around the take-up shaft 12. An encoding sensing sheet is fixedly mounted on one of the tension rollers 30, and a photoelectric sensor 31 adapted to the encoding sensing sheet is mounted on the mounting plate 3.

[0077] In the above technical solution, the photoelectric sensor 31 can be a T-type sensor with model number EE-SX672A. When the take-up shaft 12 rotates, the movement of the cleaning strip will drive the tension roller 30 to rotate passively. The tension roller 30 will drive the coding sensor to rotate, which will trigger the photoelectric sensor 31. The number of times the photoelectric sensor 31 is triggered can be used to count the length of the cloth roll 5 in real time, and promptly remind the equipment operator to replace the cloth roll 5.

[0078] When the fabric roll 5 breaks, the tension roller 30 cannot be driven to rotate, and the photoelectric sensor 31 cannot be triggered. Therefore, the abnormal fabric breakage of the fabric roll 5 can also be detected by the photoelectric sensor 31.

[0079] In a preferred embodiment of the present invention, the edge of the mounting plate 3 is bent to form a housing 32, and an openable door 33 is mounted on the housing 32. A transparent observation part 34 is provided on the door 33, and the cleaning block 4 extends downward through the housing 32.

[0080] In the above technical solution, the housing 32 is also equipped with an operation indicator light so that the operator can observe the operating status of the equipment. The usage of the cloth roll 5 can be observed through the transparent observation part 34, and the cloth roll 5 can be replaced by opening the door 33.

[0081] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0082] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0083] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
