Detailed Implementation
[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of this utility model easier to understand and master. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0023] This embodiment provides a towel machine, such as Figure 1-4As shown, the machine includes a main body 100, a towel-making device, a hot water system, a towel receiving box 200, and a computer system motherboard 300. An object sensor connected to the computer system motherboard 300 is located above the towel receiving box 200. When the towel rolls 210 in the receiving box 200 are above a preset position, the computer system motherboard 300 controls the towel machine to stop making towels. When the towel rolls 210 accumulate to the preset position, the object sensor sends a trigger signal to the computer system motherboard 300. Upon receiving the signal, the computer system motherboard 300 immediately controls the towel-making device to stop working, pausing the towel production process to prevent towel overflow due to over-making. The machine automatically stops when the capacity threshold is reached, requiring no manual intervention and achieving intelligent control. In traditional designs, towels overflowing from the receiving box 200 may be caught in the towel-making device, causing towel jamming. The improved design eliminates this potential hazard at the source through capacity control, reducing equipment downtime for maintenance, minimizing component wear caused by towel jamming, and extending the equipment's lifespan. To prevent the top towel roll 210 from being exposed outside the towel receiving box 200, which would cause it to cool and dry quickly, the towels used by the user are always kept at a suitable temperature and humidity.
[0024] like Figure 1-4 As shown, the towel-making device includes a towel-rolling mechanism 410. The object sensor is located below the towel-rolling mechanism 410. The object sensor includes an infrared transmitter 510 and an infrared receiver 520. The towel roll 210 in the towel receiving box 200 is located below and between the infrared transmitter 510 and the infrared receiver 520. The infrared transmitter 510 continuously emits infrared rays, and the infrared receiver 520 is responsible for receiving the corresponding signal. When the towel roll 210 in the towel receiving box 200 accumulates and rises to a height between the infrared transmitter 510 and the infrared receiver 520, the towel roll 210 will block the transmission path of the infrared rays, causing the signal received by the infrared receiver 520 to weaken or be interrupted. At this time, the sensor converts this signal change into an electrical signal and transmits it to the computer system motherboard 300. Based on this, the motherboard determines that the towel roll 210 in the towel receiving box 200 has reached a preset height, and then controls the towel-making device to stop working. Because the object sensor is located below the towel rolling mechanism 410, it can detect height changes in a timely and accurate manner before the towel roll 210 overflows from the towel receiving box 200, thus avoiding misjudgment or delay.
[0025] Compared to traditional contact sensors or non-contact sensors with arbitrary placement, this design features a rationally arranged infrared sensor layout, effectively reducing interference from external factors, lowering the probability of false triggering, improving the stability and reliability of the towel machine's operation, and reducing problems such as abnormal equipment shutdowns or over-processing of towels due to sensor misjudgments. In other optional embodiments, the object sensor can also be a contact sensor, such as a microswitch.
[0026] In other optional embodiments, the object sensor is an ultrasonic distance sensor, and the preset position can be flexibly adjusted by the computer system motherboard 300 to adapt to different sizes of towel receiving box 200 or towel roll 210. It also makes it easier to control the amount of towel roll 210 in the towel receiving box 200 and better control the humidity and temperature of the towel roll 210.
[0027] Furthermore, the connection between the infrared transmitter 510 and the infrared receiver 520 is horizontal. This horizontal connection design ensures that when the towel roll 210 rises to the preset height of the towel receiving box 200, it can accurately block infrared rays vertically, avoiding monitoring errors caused by tilting or misalignment. Compared to a non-horizontal connection, the horizontal layout ensures that the infrared transmission path provides the computer system motherboard 300 with more accurate information on the height of the towel roll 210, thereby achieving precise start-stop control of the towel-making device.
[0028] like Figure 1 , 3 As shown, the machine body 100 has a storage bin 110 for holding large rolls of towels 111, and a first germicidal lamp 112 is installed on the machine body 100 to irradiate the large rolls of towels 111. The storage bin 110 serves as a storage space for the large rolls of towels 111. The first germicidal lamp 112 is continuously or periodically turned on, allowing for preventative sterilization of the towels before they enter the towel-making process, reducing the risk of the towels carrying germs at the source. The germicidal lamp can be an ultraviolet lamp.
[0029] like Figure 3 As shown, a second germicidal lamp 120 is installed above the towel receiving box 200, illuminating the towel roll 210 within the receiving box 200. During the preparation and storage of the towel roll 210 in the receiving box 200, the second germicidal lamp 120 can disinfect microorganisms adhering to its surface, preventing secondary contamination caused by exposure during handling or environmental factors. This complements the first germicidal lamp 112 at the material hopper 110. The first germicidal lamp 112 ensures hygiene during the storage of the large towel roll 111, while the second germicidal lamp 120 targets the storage stage after towel production, achieving full-process sterilization and protection from raw materials to finished products, preventing microbial growth.
[0030] like Figure 2-4As shown, the towel receiving box 200 is retractably mounted on the body 100. The towel receiving box 200 has an outer baffle 220, the outer surface of which is flush with the outer surface of the body 100. When the towel receiving box 200 is fully pushed into the body 100, the outer surface of the outer baffle 220 fits tightly and is flush with the outer surface of the body 100, forming a uniform appearance. This design ensures the stability and convenience of the towel receiving box 200 during use, while maintaining the clean and streamlined overall appearance of the towel dispenser, avoiding bumps or visual abruptness caused by protruding parts. The towel receiving box 200 can be pulled out, allowing direct access to towel rolls 210, which is particularly suitable for scenarios requiring large quantities of towels, such as banquets and conferences.
[0031] like Figure 2 As shown, the body 100 includes an openable or detachable front door panel 130 with a mounting opening through which the towel dispenser 200 passes. The openable or detachable front door panel 130 is connected to the main body of the body 100 via hinges, snap-fit mechanisms, or quick-release structures, allowing for flexible opening and closing or complete removal. The mounting opening on the front door panel 130 is sized to fit the towel dispenser 200, allowing it to be smoothly inserted. When the towel dispenser 200 is pushed in, the front door panel 130 acts as an external protective barrier, securing the towel dispenser 200 and contributing to the overall appearance of the body 100. Opening or removing the front door panel 130 directly exposes the towel dispenser 200 and internal components such as the towel-making device and sensors, facilitating deep cleaning, maintenance, and repair.
[0032] like Figure 1-4As shown, the hot water system includes a heating tank 600 and a spray nozzle. A towel-making pump is installed between the spray nozzle and the heating tank 600. The towel-making device includes a towel-guiding mechanism 420, a towel-cutting mechanism 430, and a towel-rolling mechanism 410, which are configured according to the order of towel output and controlled by the computer system motherboard 300. The heating tank 600 is responsible for heating the water to a set temperature. The towel-making pump, as the power hub, pumps the hot water in the heating tank 600 to the spray nozzle under the control of the computer system motherboard 300. The spray nozzle sprays water onto the towels in a uniform mist form through a finely designed nozzle, thus wetting the towel roll 210. The towel-guiding mechanism 420 first guides the large roll of towel 111 in the hopper 110 to a designated path to ensure smooth towel delivery; the towel-cutting mechanism 430 cuts the towels according to a preset length; and the towel-rolling mechanism 410 winds the cut towel roll 210 into a standard-sized towel roll 210. Under the unified scheduling of the computer system motherboard 300, the three major components work together precisely according to the time sequence to achieve a continuous and efficient towel-making process. A heat-insulating plate 230 is located below the towel receiving box 200. The heat-insulating plate 230 can be electrically heated to keep the towel roll 210 in the towel receiving box 200 warm, thus maintaining the towel roll 210 at a suitable temperature.
[0033] Large rolls of towels 111 are placed in the hopper 110 inside the machine body 100. The first sterilization lamp 112 above the hopper 110 is turned on periodically or in real time to sterilize the towels with ultraviolet light, ensuring the hygiene of the raw materials. At the same time, the towel rolls 210 supply water to the heating tank 600 through the built-in water tank or an external water source. The heating tank 600 heats the water to the set temperature to prepare for the subsequent wetting process.
[0034] When the user operates the start switch or the number of towel rolls 210 in the towel receiving box 200 is insufficient, the computer system motherboard 300 triggers the towel making program. The towel guiding mechanism 420 first guides the large towel roll 111 out of the material hopper 110 and guides it to a fixed path; then, the towel cutting mechanism 430 cuts the towel according to the preset length; finally, the towel rolling mechanism 410 winds the cut towel roll 210 into a standard-sized towel roll 210.
[0035] During the towel roll 210 winding process, the towel-making water pump is activated under the control of the main board, pumping hot water from the heating tank 600 to the water spray unit. The water spray unit sprays hot water in a uniform mist form onto the towel through fine nozzles, achieving suitable humidity and temperature to form a warm, damp towel roll 210. Water spraying can be omitted when a dry towel is needed.
[0036] The prepared hot, moist towel roll 210 falls into the towel receiving box 200, and an object sensor above the receiving box 200 monitors the height of the towel roll 210 in real time. When the towel roll 210 accumulates to a preset position, the sensor sends a signal to the main board, which immediately controls the towel-making device and the hot water system to stop working to prevent towels from overflowing. At the same time, the second sterilizing lamp 120 above the receiving box 200 continuously or periodically sterilizes the towel roll 210 to prevent secondary contamination. Users can directly take the hot, moist towel roll 210 from the towel receiving box 200.

Those skilled in the art should understand that the utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of the utility model will be included within the scope of the claims.
