Description

Technical Field

[0001] The utility model relates to the technical field of a mop device, and particularly refers to a mop device. Background Art

[0002] A sewing machine is a commonly used fabric processing device. During the fabric sewing process, to maintain the flatness of the fabric, a mop device is usually used for mopping and feeding the fabric, that is, two mop wheels are used to clamp the fabric and convey the fabric in a specific direction, so that the fabric is always in a straightened state during the sewing process, ensuring the sewing effect and improving the sewing efficiency at the same time.

[0003] In the prior art, generally one of the two mop wheels is a fixed roller and the other is a movable roller. Among them, the movable roller needs to perform a lifting action so that the movable roller can be separated from the fixed roller, facilitating the fabric to enter between the fixed roller and the movable roller. For example, in the existing patent CN20465971U, a motor is used to provide power for the lifting of the movable roller, and other motors are used to provide power for the rotation of the fixed roller and the movable roller. Overall, more than two motors are required, which will cause problems such as large occupied volume and high cost. The existing patent CN218910738U discloses using one motor to provide power for both the lifting of the drag wheel and the rotation of the bottom wheel and the drag wheel at the same time, which saves cost and reduces the overall occupied volume of the device. However, there is a problem: when the output shaft of the motor rotates forward to drive the drag wheel to press down, it simultaneously drives the bottom wheel and the drag wheel to rotate and mop the fabric. Then, when the output shaft of the motor rotates reversely to drive the drag wheel to rise, the bottom wheel and the drag wheel will still rotate, but the rotation direction is opposite to the initial rotation direction, which will drive a section of the fabric to move back until the drag wheel is completely separated from the fabric, resulting in wrinkles in the fabric. It is necessary to manually straighten it before sewing the remaining fabric, greatly affecting the sewing efficiency. Summary of the Utility Model

[0004] The present utility model is made in consideration of the foregoing problems. The purpose of the utility model is to provide a mop device that can realize the separate control of the lifting action of the movable roller and the rotation actions of the movable roller and the fixed roller by a driving motor, and the two actions do not affect each other, which not only reduces the cost but also does not affect the sewing efficiency.

[0019] The connection point of the connecting rod and the crankshaft is far from the center of the circle of the crankshaft end face.

[0020] For a mop device as described above, the lifting assembly further includes a follower wheel and a limit sensor. The follower wheel is connected to the crankshaft and is located inside the first housing. The limit sensor is fixed to the top of the first housing and is located directly above the follower wheel.

The output shaft of the driving motor is connected to the transmission component through a first one-way bearing and to the lifting component through a second one-way bearing, and the rotation directions of the first one-way bearing and the second one-way bearing are opposite. When the output shaft of the driving motor is working, no matter which direction the output shaft rotates, it can only drive one of the first one-way bearing and the second one-way bearing to act together. Thus, the lifting action of the movable roller and the separate actions of the rotation of the movable roller and the fixed roller can be realized. That is, when the movable roller is lifted, the rotation action of the movable roller and the fixed roller stops, avoiding the backflow of the fabric, which not only reduces the cost and the occupied space, but also ensures the sewing efficiency.

[0027] 2. By using a limit sensor, it can detect the rotation angle of the follower wheel, and thus can realize the detection of the rotation angle of the crankshaft. Furthermore, the lifting height of the movable roller can be judged. A maximum lifting height of the movable roller can be set. Then, when the limit sensor detects that the movable roller is lifted to this height, it feeds back a signal to the driving motor to control it to stop operating, which can improve the overall safety performance.

[0028] 3. A first outer cover and a second outer cover are arranged on the base, which can provide protection for the transmission component and the lifting component, and can prevent the transmission component and the lifting component from being eroded by dust, water mist, etc. Description of the Drawings

[0041] The following are specific embodiments of the present invention and in combination with the accompanying drawings, the technical solutions of the present invention will be further described, but the present invention is not limited to these embodiments.

[0042] As Figures 1-5 shown, a mop device includes a frame 100, a motor assembly 200 located on the frame 100, a mop wheel set 300, a transmission assembly 400, and a lifting assembly 500.

[0043] Among them, the motor assembly 200 includes a driving motor 210, which is fixed on the frame 100. The mop wheel set 300 includes a fixed roller 310 and a movable roller 320. The fixed roller 310 is rotatably fixed on the frame 100. The movable roller 320 is arranged above the fixed roller 310 in a liftable manner. The movable roller 320 can be lowered to contact the fixed roller 310 to clamp the cloth. The two rotate synchronously in opposite directions, which can drive the clamped cloth to displace and realize mopping. In this embodiment, the motor assembly 200 includes a driving motor 210, which can control the transmission assembly 400 or the lifting assembly 500 to act independently, so as to realize that one driving motor 210 controls two actions to be carried out independently and avoid interference between the two actions.

[0044] Specifically, the transmission assembly 400 includes a driving wheel, a first driven wheel coaxially arranged with the fixed roller 310, and a second driven wheel coaxially arranged with the movable roller 320. The driving wheel is connected to the output shaft 211 of the driving motor 210 through a first one-way bearing 411, and is used to drive the first driven wheel and the second driven wheel to rotate synchronously in opposite directions, thereby driving the fixed roller 310 and the movable roller 320 to rotate in opposite directions to realize the mopping action. The lifting assembly 500 is connected to the movable roller 320. The lifting assembly 500 is connected to the output shaft 211 of the driving motor 210 through a second one-way bearing 521, and can drive the movable roller 320 to rise by rotation. In this embodiment, the rotation directions of the first one-way bearing 411 and the second one-way bearing 521 are opposite. Since both the first one-way bearing 411 and the second one-way bearing 521 are connected to the output shaft 211 of the driving motor 210, when the output shaft 211 of the driving motor 210 rotates in any direction, only one one-way bearing can be driven to rotate with it, and the other one-way bearing will be locked because it does not conform to its rotation direction. In the locked state, the output shaft 211 idles in this one-way bearing and cannot drive it to rotate. Therefore, by switching the rotation direction of the output shaft 211, the control switching of the transmission assembly 400 or the lifting assembly 500 can be realized, that is, when the transmission assembly 400 drives the fixed roller 310 and the movable roller 320 to rotate, the lifting assembly 500 does not act, or when the lifting assembly 500 works to drive the movable roller 320 to rise, the transmission assembly 400 does not act. Since only one driving motor 210 is used, the cost can be effectively reduced, and there is no interference between the two actions at all. When the movable roller 320 rises, both the movable roller 320 and the fixed roller 310 remain in a non-rotating state, avoiding driving the fabric to move backward and improving the sewing efficiency.

[0045] Among them, the first one-way bearing 411 and the second one-way bearing 521 are standard parts. A one-way bearing refers to a bearing that allows it to rotate freely in one direction and lock in the other direction. In this embodiment, when the rotation direction of the output shaft 211 is the same as the allowed rotation direction of the first one-way bearing 411 or the second one-way bearing 521, the output shaft 211 can drive the first one-way bearing 411 or the second one-way bearing 521 to rotate. When the rotation direction of the output shaft 211 is opposite to the allowed rotation direction of the first one-way bearing 411 or the second one-way bearing 521, the output shaft 211 idles in the first one-way bearing 411 or the second one-way bearing 521. The opposite rotation directions of the first one-way bearing 411 and the second one-way bearing 521 mean that the allowed rotation directions of the two are opposite. Therefore, no matter whether the output shaft 211 rotates clockwise or counterclockwise, it can only drive one one-way bearing to rotate with it. By switching the rotation direction of the output shaft 211, the independent execution of the two actions can be realized.

[0046] In this embodiment, when the output shaft 211 rotates in the first direction, the first one-way bearing 411 can rotate with the output shaft 211, the second one-way bearing 521 is locked, the output shaft 211 idles in the second one-way bearing 521, and the output shaft 211 can drive the driving wheel to rotate through the first one-way bearing 411. At this time, the driving wheel drives the first driven wheel and the second driven wheel to rotate synchronously, thereby realizing the synchronous rotation of the movable roller 320 and the fixed roller 310 to perform the mopping action; when the output shaft 211 rotates in the second direction, the first one-way bearing 411 is locked, the output shaft 211 idles in the first one-way bearing 411, the second one-way bearing 521 can rotate with the output shaft 211, and the output shaft 211 can drive the lifting assembly 500 to rotate through the second one-way bearing 521, so as to realize the independent control of the transmission assembly 400 and the lifting assembly 500.

[0047] Among them, in this embodiment, the first direction is set as the counterclockwise direction, and the second direction is set as the clockwise direction. Of course, the first direction can also be set as the clockwise direction, and the second direction can be set as the counterclockwise direction. The rotation direction can be selected according to the structural arrangement.

[0048] Specifically, the frame 100 includes a base 110, a first mounting plate 120, a first mounting seat 130, a second mounting seat 140, a first rotating shaft 150, a second rotating shaft 180, a first housing 160 and a second housing 170. The first mounting plate 120, the first mounting seat 130 and the second mounting seat 140 are all arranged vertically on the base 110. The first mounting seat 130 and the second mounting seat 140 are both located on the same side of the first mounting plate 120. A first area and a second area are arranged oppositely on the base 110. The first mounting plate 120 is installed in the first area, and the first mounting seat 130 and the second mounting seat 140 are arranged at intervals in the second area. All three are used to provide support for the installation of other components. The first housing 160 is located inside the first mounting plate 120, and it encloses a closed accommodating cavity with the first mounting plate 120. The transmission assembly 400 and a part of the lifting assembly 500 are both located inside the first housing 160, while the second housing 170 is located on the side of the first housing 160 away from the first mounting plate 120. The pressing assembly 600, a part of the lifting assembly 500, the first mounting seat 130 and the second mounting seat 140 are all located inside the second housing 170. The two housings can provide protection for the components inside, preventing them from being directly exposed to the air and avoiding the erosion of impurities such as dust and water vapor.

[0049] Among them, the drive motor 210 is fixed on the first mounting plate 120, and its output shaft 211 can extend into the first housing 160 to drive related components to act. The first rotating shaft 150 is rotatably fixed between the first mounting plate 120 and the second mounting seat 140, and the second rotating shaft 180 is rotatably fixed inside the first mounting plate 120. Both are used to provide rotational support for other components.

[0050] Among them, the fixed roller 310 is rotatably fixed on the outside of the first mounting seat 130 through the first transmission shaft 311. One end of the first transmission shaft 311 is rotatably connected to the first mounting plate 120, and the other end of the first transmission shaft 311 passes through the first mounting seat 130 and is connected to the fixed roller 310. The first driven wheel is fixed on the first transmission shaft 311. When the output shaft 211 of the drive motor 210 drives the driving wheel to rotate, the driving wheel will drive the first driven wheel to rotate, and then drive the fixed roller 310 to rotate synchronously through the first transmission shaft 311.

[0051] Furthermore, in this embodiment, the driving wheel is set as the driving gear 410, the first driven wheel is set as the first driven gear 420, the second driven wheel is set as the second driven gear 430. The transmission assembly 400 further includes a first transmission gear 440 and a second transmission gear 450. The driving gear 410 meshes with the first transmission gear 440, and the first transmission gear 440 meshes with the second transmission gear 450 and the second driven gear 430 at the same time. The second transmission gear 450 meshes with the first driven gear 420. Among them, the first transmission gear 440 is rotatably arranged on the first rotating shaft 150, and the second transmission gear 450 is rotatably arranged on the second rotating shaft 180. That is, in this embodiment, the gear transmission method is adopted to drive the fixed roller 310 and the movable roller 320 to rotate in the opposite direction. The rotation direction of the fixed roller 310 is the same as that of the first driven gear 420, the rotation direction of the movable roller 320 is the same as that of the second driven gear 430, and the rotation direction of the driving gear 410 is the same as that of the output shaft 211. Taking the output shaft 211 rotating counterclockwise as an example, it drives the driving gear 410 to rotate counterclockwise. The driving gear 410 drives the first transmission gear 440 to rotate clockwise. The first gear drives the second transmission gear 450 and the second driven gear 430 to rotate counterclockwise. The second driven gear 430 drives the movable roller 320 to rotate counterclockwise, while the second transmission gear 450 drives the first driven gear 420 to rotate clockwise. The first driven gear 420 drives the fixed roller 310 to rotate clockwise, thereby realizing that the rotation directions of the fixed roller 310 and the movable roller 320 are opposite, which is convenient for the two to cooperate in the mopping action.

[0052] Specifically, the lifting component 500 includes an eccentric unit and a lifting frame 510. One end of the lifting frame 510 is hinged to the first rotating shaft 150. The movable roller 320 is rotatably fixed to the end of the lifting frame 510 away from the first rotating shaft 150 through a second transmission shaft 321. The second transmission shaft 321 is arranged on the lifting frame 510. The second driven wheel is fixed to the second transmission shaft 321. One end of the eccentric unit is connected to the output shaft 211 through a second one-way bearing 521, and the other end of the eccentric unit is connected to the middle part of the lifting frame 510. When the second one-way bearing 521 rotates with the output shaft 211, it drives the eccentric unit to rotate. However, the rotation of the eccentric unit will adjust the distance between its connection point with the lifting frame 510, thereby driving the lifting frame 510 to rotate around the first rotating shaft 150. By controlling the rotation direction of the eccentric unit, the end of the lifting frame 510 away from the first rotating shaft 150 can be lifted or lowered. Both its lifting and lowering can drive the movable roller 320 to perform up and down movements. When the movable roller 320 is lifted, it can be separated from the fixed roller 310, facilitating the placement of fabric between the two.

[0053] Further, the eccentric unit includes a crankshaft 520 and a connecting rod 530. The crankshaft 520 is connected to the output shaft 211 through a second one-way bearing 521. One end of the connecting rod 530 is connected to the end of the crankshaft 520, and the other end of the connecting rod 530 is connected to the middle part of the lifting frame 510. Among them, the connection point of the connecting rod 530 and the crankshaft 520 is far from the center of the end face of the crankshaft 520. That is, when the crankshaft 520 rotates with the output shaft 211, it drives the connecting rod 530 to perform eccentric motion, thereby realizing the control of the lifting frame 510.

[0054] Even further, the lifting component 500 further includes a follower wheel 540 and a limit sensor 550. The follower wheel 540 is connected to the crankshaft 520 and is located inside the first housing 160. The limit sensor 550 is fixed to the top of the first housing 160 and is located directly above the follower wheel 540. The limit sensor 550 is used to detect the rotation angle of the follower wheel 540 and is electrically connected to the drive motor 210. The maximum lifting height of a movable roller 320 can be set, and this maximum lifting height is converted into the rotation angle of the follower wheel 540. When the follower wheel 540 rotates this rotation angle, the limit sensor 550 feeds back a signal to the drive motor 210 to control the drive motor 210 to stop operating, thereby playing a role in limiting the movable roller 320, improving the overall safety performance, and reducing energy consumption at the same time.

[0055] Specifically, the pressing component 600 includes a support frame 610, a guide rod 620, and a pressing spring. One end of the support frame 610 is fixed to the outer side of the first housing 160. One end of the guide rod 620 is fixed to the top of the lifting frame 510 away from one end of the first rotating shaft 150. The other end of the guide rod 620 is passed through the support frame 610. The pressing spring is sleeved on the guide rod 620 and is located between the support frame 610 and the lifting frame 510, and the pressing spring is in a compressed state. When the movable roller 320 and the fixed roller 310 are in a contact state, the pressing spring is in a compressed state. When the end of the lifting frame 510 where the movable roller 320 is fixed is lifted, the pressing spring will be further compressed. After the steering of the output shaft 211 is switched, at this time, the lifting frame 510 is not subjected to the lifting force, and the elastic force of the pressing spring can drive the end of the lifting frame 510 to descend and drive the movable roller 320 to remain in contact with the fixed roller 310.

[0056] In this embodiment, a mop device is disclosed, which includes a frame 100, a motor assembly 200 located on the frame 100, a mop wheel set 300, a transmission assembly 400, and a lifting assembly 500. The motor assembly 200 includes a driving motor 210. The mop wheel set 300 includes a fixed roller 310 and a movable roller 320. The transmission assembly 400 includes a driving wheel, a first driven wheel coaxially arranged with the fixed roller 310, and a second driven wheel coaxially arranged with the movable roller 320. The driving wheel is connected to the output shaft 211 of the driving motor 210 through a first one-way bearing 411 and is used to drive the first driven wheel and the second driven wheel to rotate synchronously in opposite directions. The lifting assembly 500 is connected to the movable roller 320. The lifting assembly 500 is connected to the output shaft 211 of the driving motor 210 through a second one-way bearing 521 and can drive the movable roller 320 to rise by rotation. Among them, the rotation directions of the first one-way bearing 411 and the second one-way bearing 521 are opposite. Then, by adjusting the rotation direction of the driving motor 210, the driving motor 210 can be controlled to drive either the first one-way bearing 411 or the second one-way bearing 521 to rotate accordingly, so as to realize the independent actions of the transmission assembly 400 and the lifting assembly 500, avoid the mutual influence of the two actions, and improve the sewing speed on the premise of reducing costs.
