Description

Technical Field

[0001] This utility model relates to the technical field of washing machine equipment, specifically to the modification of the transmission device for a washing machine. Background Technology

[0002] To facilitate the promotion of brands and products, advertising equipment is often used, among which advertising projection equipment is a commonly used advertising display device. Utility model patent application number CN202121976325.5 discloses a novel fabric washing machine. The rotating screen is driven by a motor, which not only increases the cleanliness of the fabric during washing through protruding strips, but also spins the fabric dry using the rotating screen. The belt drive increases the rotation speed of the rotating screen, thereby accelerating the drying process. During the washing process, a heating conduit increases enzyme activity, improving the cleanliness of the fabric. During the spin-drying process, the heating conduit... This process heats the air inside the drum cavity, causing the moisture in the fabric to turn into water vapor and enter the heat dissipation vent with the air. The air is then expelled by the exhaust fan in the radiator. According to the publicly available technical solution, existing washing machine equipment has several drawbacks. First, when driving the multiple washing mechanisms within the washing machine, the conventional belt rotation is prone to slippage when the belt loosens, which is detrimental to ensuring the transmission operation of the washing machine and reduces its working efficiency. Second, when the belt tension is maintained by the pressure roller, if the belt loosens further, manual tensioning is often required, increasing manpower consumption and compromising the stability of the belt drive.

[0003] Therefore, how to design the transmission device for the modified washing machine has become the problem we need to solve. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a modified transmission device for washing machines to solve the problems mentioned in the background. This utility model is reasonably designed, convenient to use, and suitable for transmission of the washing mechanism of washing machines.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modified transmission device for a washing machine, comprising a pulley and a transmission wheel. A transmission assembly is mounted on the pulley, the transmission assembly comprising a belt and a connecting shaft. A tensioning assembly is mounted on the belt, the tensioning assembly comprising a pressure wheel and a sliding sleeve. A sliding assembly is mounted on the sliding sleeve, the sliding assembly comprising a slider and a support rod. A pushing assembly is mounted on the sliding sleeve, the pushing assembly comprising a motor and a lead screw. A pressing assembly is mounted on the inner side of the sliding sleeve, the pressing assembly comprising a pressure block and a first spring. A control assembly is mounted on the slider, the control assembly comprising a button and a second spring.

[0006] Furthermore, the center of both the pulley and the drive wheel is mounted on the outer side of one end of the connecting shaft, and the two ends of the belt are sleeved on the inner sides of the pulley and the drive wheel. The pulley drives the drive wheel through the belt.

[0007] Furthermore, the sliding sleeve is installed on the outside of the belt, and a sliding groove is provided on the inner side of the sliding sleeve. The outer side of the slider is engaged with the inner side of the sliding groove, and one side of the slider passes through the sliding groove and extends to the outer side of the sliding sleeve.

[0008] Furthermore, one end of the support rod is welded to one side of the slider, the pressure roller is mounted on the outer side of the support rod via a bearing, and the bottom of the pressure roller is clamped onto the inner wall of the bottom of the belt.

[0009] Furthermore, the motor is bolted to the bottom of the sliding sleeve, the bottom end of the lead screw passes through the inner wall of the bottom of the sliding sleeve via a bearing and is keyed to the output shaft of the motor, and the top end of the lead screw is mounted on the inner wall of the top of the sliding sleeve via a bearing.

[0010] Furthermore, the outer side of the pressure block is engaged with the inner wall of the slide groove, and the bottom of the pressure block is connected to the top of the slider by a spring.

[0011] Furthermore, the inner side of the pressure block is provided with an internal thread, the outer side of the lead screw is provided with an external thread, the internal thread and the external thread are engaged, and the inner side of the slider is provided with a through-hole, which is sleeved on the outer side of the external thread.

[0012] Furthermore, the bottom of the button is connected to the top of the slider via a spring, the button is located at the bottom of the pressure block, the button is connected to the motor via a wire, and the button is a normally open push-button switch.

[0013] Beneficial effects: 1. When using the modified transmission device of this washing machine, the pulley and drive wheel are connected to multiple sets of cleaning mechanisms inside the washing machine through couplings, and the sliding sleeve is installed on the outer side of the washing machine. The pressure wheel is used to squeeze the bottom of the belt downward, so that the belt, pulley and drive wheel can maintain a high tension, thereby effectively preventing the belt from slipping due to loosening between the belt and pulley and drive wheel, ensuring the transmission efficiency of the washing machine, and thus ensuring the cleaning quality of the washing machine.

[0014] 2. When the modified transmission device of this washing machine is tensioning the belt, the motor drives the pressure block to move downward inside the sliding sleeve via the lead screw. This causes the pressure block to press the slider downward via spring one. The slider slides downward inside the sliding groove and drives the pressure roller to press the belt downward via the support rod until the pressure roller clamps the bottom of the belt. The pressure block compresses spring one and continues to move downward until the pressure block presses the button, at which point the motor stops working. If the belt becomes slack during operation, the spring force of spring one causes the slider to move downward via the support rod to move the pressure roller, maintaining the belt tension. The slider drives the button downward via spring two, separating the button from the pressure block. The motor then drives the pressure block downward via the lead screw until the pressure block presses the top of the button again. This allows the belt to automatically tension itself after slack, eliminating the need for frequent inspection and adjustment by personnel, saving manpower, and ensuring stable belt tension, thus guaranteeing stable transmission operation of the washing machine.

[0015] 3. The modified transmission device of this washing machine is reasonably designed, highly efficient and convenient to use, and suitable for transmission in the washing machine's cleaning mechanism. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 2This utility model provides a technical solution: a modified transmission device for a washing machine, including a pulley 1 and a transmission wheel 2. A transmission assembly is mounted on the pulley 1, the transmission assembly including a belt 3 and a connecting shaft 4. A tensioning assembly is mounted on the belt 3, the tensioning assembly including a pressure wheel 5 and a sliding sleeve 6. A sliding assembly is mounted on the sliding sleeve 6, the sliding assembly including a slider 8 and a support rod 9. A pushing assembly is mounted on the sliding sleeve 6, the pushing assembly including a motor 10 and a lead screw 11. A pressing assembly is mounted on the inner side of the sliding sleeve 6, the pressing assembly including a pressure block 12 and a spring 13. A control assembly is mounted on the slider 8, the control assembly including a button 14 and a spring 15. The centers of the pulley 1 and the transmission wheel 2 are both mounted on the outer side of one end of the connecting shaft 4. The two ends of the belt 3 are sleeved on the inner sides of the pulley 1 and the transmission wheel 2. The pulley 1 drives the transmission wheel 2 through the belt 3. In the transmission system, the sliding sleeve 6 is installed on the outside of the belt 3, and a groove 7 is provided on the inner side of the sliding sleeve 6. The outer side of the slider 8 is engaged with the inner side of the groove 7, and one side of the slider 8 passes through the groove 7 and extends to the outer side of the sliding sleeve 6. One end of the support rod 9 is welded to one side of the slider 8. The pressure roller 5 is installed on the outer side of the support rod 9 through a bearing, and the bottom of the pressure roller 5 is engaged with the inner wall of the bottom of the belt 3. In use, the pulley 1 and the drive wheel 2 are connected to multiple sets of cleaning mechanisms in the washing machine through the connecting shaft 4, and the sliding sleeve 6 is installed on the outer side of the washing machine. The pressure roller 5 is used to press the bottom of the belt 3 downward, so that the belt 3 can maintain a high tension with the pulley 1 and the drive wheel 2, thereby effectively preventing the belt 3 from slipping due to loosening between the belt 3 and the pulley 1 and the drive wheel 2, ensuring the transmission efficiency of the washing machine, and thus ensuring the cleaning quality of the washing machine.

[0021] In this embodiment, the motor 10 is bolted to the bottom of the sliding sleeve 6. The bottom end of the lead screw 11 passes through the inner wall of the bottom of the sliding sleeve 6 via a bearing and is keyed to the output shaft of the motor 10. The top end of the lead screw 11 is mounted on the inner wall of the top of the sliding sleeve 6 via a bearing. The outer side of the pressure block 12 is engaged with the inner wall of the slide groove 7. The bottom of the pressure block 12 is connected to the top of the slider 8 via a spring 13. The inner side of the pressure block 12 has an internal thread, and the outer side of the lead screw 11 has an external thread. The internal thread and the external thread mate. The inner side of the slider 8 has a through-hole, which fits around the outer side of the external thread. The bottom of the button 14 is connected to the top of the slider 8 via a spring 2 15. The button 14 is located at the bottom of the pressure block 12 and is connected to the motor 10 via a wire. The button 14 is a normally open push-button switch. When tensioning the belt 3, the motor 10 drives the pressure block 12 downwards inside the sliding sleeve 6 via the lead screw 11. The movement causes the pressure block 12 to press down on the slider 8 via the spring 13. The slider 8 slides downward inside the groove 7 and, through the support rod 9, drives the pressure roller 5 to press down on the belt 3 until the pressure roller 5 clamps the bottom of the belt 3. The pressure block 12 then compresses the spring 13 and continues to move downward until the pressure block 12 presses down on the button 14, at which point the motor 10 stops working. If the belt 3 becomes slack during operation, the spring force of the spring 13 causes the slider 8 to move downward through the support rod 9, driving the pressure roller 5 to maintain the tension of the belt 3. The slider 8, through the spring 2 15, drives the button 14 downward, thus separating the button 14 from the pressure block 12. The motor 10 then drives the pressure block 12 downward through the lead screw 11 until the pressure block 12 presses down on the top of the button 14 again. This allows the belt 3 to be automatically tensioned after it becomes slack, eliminating the need for frequent checks and adjustments by personnel, saving manpower, and ensuring the stable tension of the belt 3, thereby ensuring the stable transmission of the washing machine.

[0022] The modified transmission device of this washing machine provides power to all electrical equipment via an external power source. During operation, pulley 1 and drive wheel 2 are connected to multiple cleaning mechanisms within the washing machine via coupling 4. Sliding sleeve 6 is installed on the outer side of the washing machine. Pressure roller 5 presses the bottom of belt 3 downwards, maintaining high tension between belt 3 and pulleys 1 and 2. This effectively prevents slippage and ensures the transmission efficiency and cleaning quality of the washing machine. During belt tensioning, motor 10 drives pressure block 12 downwards inside sliding sleeve 6 via lead screw 11. This pressure block 12 then presses down on slider 8 via spring 13. Sliding slider 8 slides downwards inside groove 7 and is driven by support rod 9. The pressure roller 5 presses down on the belt 3 until it clamps the bottom of the belt 3. The pressure block 12 compresses the spring 13 and continues to move downward until it presses down on the button 14. The motor 10 stops working. If the belt 3 becomes slack during operation, the spring force of the spring 13 causes the slider 8 to move downward through the support rod 9, which drives the pressure roller 5 to maintain the tension of the belt 3. The slider 8 drives the button 14 downward through the spring 15, which separates the button 14 from the pressure block 12. The motor 10 then drives the pressure block 12 downward through the lead screw 11 until the pressure block 12 presses down on the top of the button 14 again. This allows the belt 3 to be automatically tensioned after it becomes slack, eliminating the need for frequent inspection and adjustment by personnel, saving manpower, and ensuring that the tension of the belt 3 remains stable, thus ensuring the stable transmission of the washing machine.
