As one of the key factors affecting these performances, rotating balance is directly related to the overall quality of the washing machine and user experience.

[0003] The drum of the washing machine will affect the rotating balance of the washing machine, such as uneven thickness of the drum material, which will cause uneven mass distribution and produce unbalanced force when rotating. In addition, if the shape of the drum is not standard, such as ovality and cylindricity out of tolerance, the center of gravity trajectory will deviate from the center axis when rotating, causing vibration, so we need to detect the rotating balance of the drum inside the washing machine.

[0004] In the washing machine production process, due to the rich variety of washing machine models, the capacity and diameter of the internal drum are also different. However, most of the rotating balance detection devices for washing machine production on the market lack a fixing device that can adapt to different diameter drums, making it difficult to flexibly respond to detection objects of different sizes. This results in the need to frequently replace equipment or perform complex debugging when detecting the drum of different models of washing machines, greatly reducing detection efficiency and hindering the efficient advancement of the production process.

[0005] Therefore, there is an urgent need for a rotating balance detection device for washing machine production to solve the above problems. Utility model content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] Please refer to Figures 1 to 6 The utility model provides an embodiment: a rotating balance detection device for washing machine production, including rotating motor 11, rotating motor 11 is the detection device drive roller 7 rotation power supply, rotating motor 11 is installed with drive shaft 12, the rotation axis of roller 7 is inserted into the inside of drive shaft 12, and roller 7 is driven to rotate by drive shaft 12. Drive shaft 12 is fixedly installed with fixing mechanism 2 on the end far from rotating motor 11, and rotating motor 11 transmits power to fixing mechanism 2 fixedly installed on the outside of drive shaft 12 through drive shaft 12, and fixing mechanism 2 rotates with roller 7 together by the power provided by rotating motor 11, so as to fix roller 7, prevent roller 7 from separating from the detection device when rotating balance detection is carried out, and cause harm to the surrounding staff.

[0022] The fixing mechanism 2 comprises a fixing block 21, a plurality of horizontal arm sleeves 22, a plurality of connecting rods 23, a plurality of vertical arm sleeves 24, a plurality of telescopic rods 25 and a plurality of locking blocks 26, and the specific quantity is that the fixing mechanism 2 has one fixing block 21, the fixing block 21 is a cuboid, four horizontal arm sleeves 22 are fixedly installed on the four sides of the fixing block 21, one connecting rod 23 is slidably connected in each horizontal arm sleeve 22, one vertical arm sleeve 24 is fixedly installed at the end, away from the fixing block 21, of each connecting rod 23, one telescopic rod 25 is slidably installed in each vertical arm sleeve 24, and one locking block 26 is installed at the top of each telescopic rod 25. Therefore, the fixing mechanism 2 comprises one fixing block 21, four horizontal arm sleeves 22, four connecting rods 23, four vertical arm sleeves 24, four telescopic rods 25 and four locking blocks 26. The fixing block 21 is fixedly installed on the outside of the driving shaft 12 and rotates with the driving shaft 12, so as to drive the horizontal arm sleeves 22 fixedly installed on the fixing block 21 to rotate, so that the whole fixing mechanism 2 rotates with the roller 7. The connecting rod 23 is slidably installed in the horizontal arm sleeve 22, and workers can hold the end of the connecting rod 23 exposed outside the horizontal arm sleeve 22, put the connecting rod 23 into the horizontal arm sleeve 22 or pull the connecting rod 23 out of the horizontal arm sleeve 22, so as to reduce or increase the diameter of the roller 7 that can be fixed by the fixing mechanism 2. The vertical arm sleeve 24 is fixedly installed at the end, away from the fixing block 21, of the connecting rod 23, so as to drive the telescopic rod 25 and the locking block 26 to move in the horizontal direction. The telescopic rod 25 is slidably installed in the vertical arm sleeve 24, and workers can hold the end of the telescopic rod 25 exposed outside the vertical arm sleeve 24, put the telescopic rod 25 into the vertical arm sleeve 24 or pull the telescopic rod 25 out of the vertical arm sleeve 24, so as to reduce or increase the height of the roller 7 that can be fixed by the fixing mechanism 2. The locking block 26 is fixed at the top of the telescopic rod 25, so as to fix the roller 7 from the top of the roller 7.

[0023] Specifically, the horizontal arm sleeve 22 is internally rotatably inserted with a fixing nut 3 at the end away from the fixed block 21, and the vertical arm sleeve 24 is internally rotatably inserted with a fixing nut 3 at the end away from the connecting rod 23. The fixing nut 3 penetrates the end surface of the horizontal arm sleeve 22 and the vertical arm sleeve 24, and is in contact with the surface of the connecting rod 23 and the surface of the telescopic rod 25. Since the horizontal arm sleeve 22 and the vertical arm sleeve 24 each have four, the fixing nut 3 has eight in total. When the fixing nut 3 penetrates the inner wall of the horizontal arm sleeve 22 and the vertical arm sleeve 24, one end of the fixing nut 3 is in contact with the surface of the connecting rod 23 and the surface of the telescopic rod 25. As the fixing nut 3 continues to rotate in, the contact surface pressure between the fixing nut 3 and the surface of the connecting rod 23 and the surface of the telescopic rod 25 also gradually increases, thereby locking the position of the connecting rod 23 and the telescopic rod 25 inside the horizontal arm sleeve 22 and the vertical arm sleeve 24. The horizontal arm sleeve 22 and the connecting rod 23, the vertical arm sleeve 24 and the telescopic rod 25 stably maintain the current positional relationship, preventing free movement between the horizontal arm sleeve 22 and the connecting rod 23, the vertical arm sleeve 24 and the telescopic rod 25, and affecting the actual application effect.

[0024] Specifically, the driving shaft 12 is rotatably installed with a chassis 41, and the chassis 41 is located between the rotating motor 11 and the fixed block 21. The chassis 41 and the fixed block 21 have enough distance between them. The purpose is that when the staff aligns the rotating shaft of the roller 7 with the driving shaft 12 of the rotating motor 11 and puts the roller 7 into the fixed mechanism 2, the distance between the chassis and the fixed block 21 is enough for the staff to put their hand into the fixing nut 3 on the horizontal arm sleeve 22 and rotate the fixing nut 3 into the inside of the horizontal arm sleeve 22.

[0025] The bottom plate 41 is fixedly installed with a plug 42 on the side facing the fixed block 21, the plug 42 is inserted and connected with the insertion hole 53 at the bottom of the shell 51, so as to achieve the effect of fixing the shell 51, preventing the shell 51 from moving on the bottom plate 41 and threatening the safety of the rotating balance detection. The bottom plate 41 is fixedly installed with a supporting spring 44 on the side facing the rotating motor 11, and the supporting spring 44 is installed with a pressure sensor 43 at the end away from the bottom plate 41. The combination of the supporting spring 44 and the pressure sensor provides support for the bottom plate 41 on the one hand, and detects the rotating balance of the roller 7 on the other hand. When the material and thickness of the roller 7 are uneven, or there are problems such as ovality and cylindricity out of tolerance, the rotating center of gravity track of the roller 7 will deviate from the center axis of the driving shaft 12, and the driving shaft 12 will produce strong shaking together with the roller 7 due to the deviation of the rotating center of gravity track of the roller 7. The strong shaking of the driving shaft 12 will drive the bottom plate 41 rotatingly installed on the outside of the driving shaft 12 to produce violent shaking. The supporting spring 44 will change the supporting force of the bottom plate 41 according to the violent shaking of the bottom plate 41, and the pressure of the supporting spring 44 on the pressure sensor 43 will also change. The pressure sensor 43 detects the strong change of the pressure of the supporting spring 44, and then conveys the information of the unbalanced rotation of the roller 7 to the worker. If the material and thickness of the roller 7 are uniform, and there are no problems such as ovality and cylindricity out of tolerance, the pressure of the supporting spring 44 detected by the pressure sensor 43 will not change violently, and the worker can take the roller 7 meeting the requirements for further fine detection.

[0026] Specifically, the bottom plate 41 is installed with the shell 51 on the side facing the fixed block 21, the plug 42 is inserted and connected with the insertion hole 53 at the bottom of the shell 51, and the top of the shell 51 is fixedly installed with a handle 52. After the roller 7 is installed, the worker can hold the handle 52 with his hand, align the insertion hole 53 at the bottom of the shell 51 with the plug 42 installed on the bottom plate 41, and install the shell 51 on the bottom plate 41.

[0027] Specifically, the top of the fixed block 21 and the bottom of the locking block 26 are installed with rubber pads 6, which can increase the friction between the fixing mechanism 2 and the roller 7, prevent unnecessary displacement of the roller 7 inside the fixing mechanism 2, and cause unnecessary influence on the rotating balance detection result.

[0028] Working principle:

[0029] The worker holds the handle 52 on the top of the shell 51 with his hand and lifts the shell 51 up. After the worker moves the shell 51 away, he first pulls the four connecting rods 23 out of the corresponding horizontal arm sleeves 22 with his hand, expands the fixing diameter of the fixing mechanism 2, and thus achieves the purpose of facilitating the worker to install the roller 7 in the fixing mechanism 2. After the worker completes the adjustment of the four connecting rods 23, he places the rotating shaft at the bottom of the roller 7 to be detected into the inside of the driving shaft 12. After the worker places the rotating shaft of the roller 7, he starts to move the fixing mechanism 2 to fix the roller 7.

[0030] Before the worker adjusts the connecting rod 23, he first holds the telescopic rod 25 and pulls it up outward, stretches it to a suitable height, and then tightens the fixing nut 3 on the vertical arm sleeve 24 to lock the telescopic rod 25, so that the locking block 26 at the top of the telescopic rod 25 does not hinder the adjustment of the connecting rod 23 when the connecting rod 23 is adjusted.

[0031] After the adjustment of the telescopic rod 25 is completed, the worker first holds any one of the connecting rods 23 with his hand, pushes the connecting rod 23 previously pulled out of the horizontal arm sleeve 22 back into the inside of the horizontal arm sleeve 22, and makes the vertical arm sleeve 24 tightly close to the outside of the roller 7 without any gap. When the worker pushes the connecting rod 23 to the target position, he stretches his hand into the bottom of the roller 7 to touch the rotating plug-in fixing nut 3 on the horizontal arm sleeve 22. After the worker's hand touches the fixing nut 3, he rotates the fixing nut 3 into the inside of the horizontal arm sleeve 22 with his hand until the fixing nut 3 contacts the connecting rod 23 in the inside of the horizontal arm sleeve 22 and cannot continue to be rotated. After the worker adjusts the telescopic adjustment of the connecting rod 23, he starts to adjust the telescopic adjustment of the telescopic rod 25. The worker loosens the fixing nut 3 on the vertical arm sleeve 24 so that the telescopic rod 25 can be telescoped. The worker holds the locking block 26 at the top of the telescopic rod 25 with his hand, moves it close to the top of the roller 7, until the rubber pad 6 at the bottom of the locking block 26 contacts the top of the roller 7 and cannot continue to move downward. At this time, the worker rotates the fixing nut 3 into the inside of the vertical arm sleeve 24 with his hand until the fixing nut 3 contacts the telescopic rod 25 in the inside of the vertical arm sleeve 24 and cannot continue to be rotated, and the fixing of the telescopic rod 25 is completed. At this time, the worker completes the fixing of one of the four groups of the fixing mechanism 2, and then the worker will repeat the above operation to fix the other three groups.

[0032] After the worker completes the fixing of the roller 7, he holds the handle 52 with his hand, aligns the insertion hole 53 at the bottom of the shell 51 with the insertion pin 42 installed on the chassis 41, and installs the shell 51 on the chassis 41.

[0033] When the work staff places the shell 51, the work staff starts the rotating motor 11 to drive the driving shaft 12 to rotate, so as to drive the drum 7 and the fixing mechanism 2 to rotate. When the material and thickness of the drum 7 are uneven, or there are problems such as out-of-tolerance of the ovality and the cylindricity, the rotating center trajectory of the drum 7 will deviate from the central axis of the driving shaft 12, and the driving shaft 12 will shake strongly along with the drum 7 due to the deviation of the rotating center trajectory of the drum 7. The strong shaking of the driving shaft 12 will drive the chassis 41 rotatingly installed outside the driving shaft 12 to shake violently. The support spring 44 will change the support force on the chassis 41 according to the violent shaking of the chassis 41, and the pressure of the support spring 44 on the pressure sensor 43 will also change. The pressure sensor 43 detects the strong change of the pressure of the support spring 44, and then transmits the information of the unbalanced rotation of the drum 7 to the work staff. The work staff will eliminate the unqualified drum 7, and process the unqualified drum 7 in the subsequent work. If the material and thickness of the drum 7 are uniform, and there are no problems such as out-of-tolerance of the ovality and the cylindricity, the pressure of the support spring 44 detected by the pressure sensor 43 will not change violently, and the work staff can take the qualified drum 7 to further fine detection.

[0034] It is apparent for those skilled in the art that the present application is not limited to the details of the above-exemplified embodiments but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Accordingly, the embodiments are to be considered in all respects as illustrative and not restrictive, the scope of the present application being indicated by the appended claims rather than by the above description, and all changes which come within the meaning and range of equivalents are intended to be embraced therein. Any reference signs in the claims should not be construed as limiting the claims.
