Technical Field

[0001] This utility model relates to the field of towel machine technology, specifically a towel machine water return structure. Background Technology

[0002] With increasing public health awareness and rising demands for quality of life, hot towel dispensers, as intelligent devices that provide warm, clean towels, are widely used in beauty salons, barbershops, spas, hotels, and medical institutions. Their main function is to heat, humidify, or dry clean towels pre-wound on conveyor rollers and automatically deliver them to the designated location for convenient use.

[0003] Existing hot towel machines typically include a main body, a towel dispensing slot on the main body, and a water tank for storing water. The water tank is connected to the main body and maintains a constant water level to support the humidification of towels or subsequent washing processes during operation, ensuring that the towels have suitable humidity and temperature for use. After the towels have completed the heating or drying process, they are conveyed to the towel dispensing slot on the main body via a conveyor system for convenient use by users. However, when towels are about to run out or have been exhausted, it is not possible to notify the operator in time to replace them with new towel rolls, which may cause the equipment to run idle, waste energy, and result in users failing to use the towels, affecting service efficiency and user experience. To address this, we propose a towel machine water return structure. Utility Model Content

[0024] 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.

[0025] Example 1

[0026] Please see Figures 1 to 7 This utility model provides a technical solution: a towel machine water return structure, including: a machine body 1, a towel taking slot 2 and a water storage tank 19. The towel taking slot 2 is opened on the machine body 1. After the towel is dried, the machine body 1 conveys the towel into the towel taking slot 2. The water storage tank 19 is connected to the machine body 1. The water storage tank 19 is used to store water. The water storage tank 19 always maintains a certain water level during the operation of the equipment to support subsequent cleaning or humidification functions.

[0027] Also includes:

[0028] The conveying chamber 3 and the driving chamber 5 are both located on the machine body 1. A conveying roller 4 is connected inside the conveying chamber 3, and a towel is wrapped around the conveying roller 4. Both ends of the conveying roller 4 are secured with fixing sleeves 8, which are used to fix the conveying roller 4. The fixing sleeves 8 enable quick mounting and positioning of the conveying roller 4 without the need for bolt tightening, improving assembly efficiency. A monitoring element 9 is connected to one end of the fixing sleeve 8 to monitor whether the towel is used up. An alarm is connected to the machine body 1 to alert the operator to check the conveying roller 4. The monitoring component 9 is used to detect the remaining amount of towels on the conveyor roller 4 in real time. When the towels are nearly used up or completely exhausted, the monitoring component 9 generates a displacement change signal, triggering the alarm on the machine body 1 to emit an audible and visual alarm. The other end of the fixed sleeve 8 is connected to a clamping component 7. When the monitoring component 9 detects that the towels are used up, the clamping component assists the staff in replacing the conveyor roller. After the towels have been used up and the alarm is triggered, the clamping force on the conveyor roller 4 can be manually released through the clamping component 7. The remaining amount can be sensed in real time, which makes it convenient for the staff to quickly remove the empty roll core and install a new roll.

[0029] A motor 6 is connected inside the drive cavity 5. The motor 6 is independently located inside the drive cavity 5 and isolated from the wet washing area to improve electrical safety. The output shaft of the motor 6 is connected to one of the fixed sleeves 8. When the motor 6 is started, it electrically drives the entire conveyor roller 4 to rotate, thereby realizing the automatic feeding of towels.

[0030] The monitoring component 9 includes a bearing 91, which is connected to one of the fixed sleeves 8. The bearing 91 is nested on the outside of the fixed sleeve 8 at the corresponding end and can rotate synchronously with the fixed sleeve 8. A connecting rod 13 is connected to the bearing 91, and a groove 15 is provided on the connecting rod 13. A monitoring plate 14 is slidably connected to the groove 15. A monitoring plate 14 is slidably fitted in the groove 15. The monitoring plate 14 can slide freely in the groove 15. When the conveying roller 4 is wrapped with a sufficient amount of towel, its outer diameter is large. The outer end of the monitoring plate 14 abuts against the surface of the towel and is pushed outward and is at the outer limit position of the groove 15.

[0031] A spring 16 is connected inside the chute 15, and the spring 16 is located between the chute 15 and the monitoring plate 14. In the initial state, the monitoring plate 14 is held in the inner position of the chute 15 by the action of the spring 16. When the towels on the conveying roller 4 gradually decrease, its outer diameter becomes smaller, causing the monitoring plate 14 to slide inward due to loss of support, compressing the spring 16.

[0032] A switch 18 is connected inside the slide 15, and a horizontal plate 20 is connected inside the slide 15. A pressure plate 17 is provided on one side of the horizontal plate 20, and the pressure plate 17 corresponds to the switch 18. When the monitoring plate 14 continues to slide inward as the towel decreases, it will push the horizontal plate 20, causing the pressure plate 17 to press the micro switch 18, thereby triggering the control circuit and activating the alarm.

[0033] A torsion spring 21 is connected between the horizontal plate 20 and the pressure plate 17. The torsion spring 21 provides a restoring force, so that the horizontal plate 20 can automatically reset after the monitoring plate 14 removes the thrust, thus avoiding false triggering or jamming.

[0034] Example 2

[0035] The clamping component 7 includes a telescopic shaft 11, which is connected to another fixed sleeve 8. A second spring 12 is fitted on the telescopic shaft 11. The telescopic shaft 11 is inserted into the fixed sleeve 8, which can move axially. The two ends of the second spring 12 abut against the end face of the fixed sleeve 8 and the telescopic shaft 11, respectively, to provide a preload force for the telescopic shaft 11, so that it remains in the extended state under normal working conditions and firmly clamps the conveyor roller 4.

[0036] Both the telescopic shaft 11 and the motor 6 are connected to a connecting plate 71. The bottom of the connecting plate 71 is connected to an electric telescopic rod 10. When the conveyor roller 4 needs to be replaced, the electric telescopic rod 10 extends and retracts, causing the connecting plate 71 to move vertically, thereby allowing the conveyor shaft to extend out of the conveyor cavity 3. This makes it easier for staff to replace the conveyor roller 4 and avoids the problem of uneven force caused by disassembly on one side.
