Abstract
Description
Technical Field
[0001] This utility model relates to the field of cold drink equipment technology, and in particular to a driving device and cold drink equipment. Background Technology
[0002] In beverage equipment (such as smoothie makers, ice cream makers, and frosting machines), the stable rotation of the evaporator is crucial for efficient ice making or freezing. Current technologies often employ a rack and pinion drive structure, where a drive motor drives a transmission belt that meshes with a rotating component, thus driving the evaporator to rotate and make ice. However, when making ice directly from water or in waterless freezing conditions, the connection between the evaporator and the rotating component is prone to ice buildup due to condensation or low temperatures, preventing the rotating component from rotating smoothly. In this situation, the meshing resistance between the transmission belt teeth and the rotating component's teeth increases sharply, easily causing slippage or abnormal wear of the teeth, leading to decreased transmission efficiency, uneven ice making, and motor damage. Furthermore, traditional structures struggle to detect early signs of tooth wear, often only addressing the issue after obvious abnormalities (such as unusual noises or interrupted ice making) have occurred, at which point the transmission system has already suffered irreversible damage. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a driving device that can monitor the rotation of rotating parts and prevent subsequent abnormal damage.
[0004] To solve the above-mentioned technical problems, this utility model provides a driving device for driving an evaporator to rotate, including a driving component, a rotating component that is pulverizedly connected to the driving component, and a transmission shaft connected to the rotating component. The transmission shaft is connected to the evaporator, and the driving component can drive the transmission shaft to rotate through the rotating component.
[0005] As an improvement to the above solution, a transmission belt is further provided between the driving member and the rotating member. The transmission belt is wound between the rotating end of the driving member and the rotating member, and the driving member can drive the rotating member to rotate through the transmission belt.
[0006] As an improvement to the above solution, the rotating component is provided with multiple toothed blocks on its circumference, and the inner side of the transmission belt can mesh with the toothed blocks, and the transmission belt drives the rotating component to rotate through the toothed blocks.
[0007] As an improvement to the above solution, the driving device further includes a rotating plate, which is fixed to one side of the rotating component and arranged along the circumferential edge of the rotating component. The rotating plate is provided with a plurality of grids, which are evenly distributed on the rotating plate along the circumference of the rotating component.
[0008] As an improvement to the above solution, the driving device further includes a fixing frame, which is fixed to the side of the rotating member. The sensing element is disposed on the fixing frame and located on the side of the rotating plate, and the sensing element is capable of detecting the grid.
[0009] As an improvement to the above solution, the sensing element is fixed to the side of the mounting bracket. The sensing element includes a transmitting end and a receiving end. The transmitting end and the receiving end extend toward the inner side of the rotating member and are respectively located on both sides of the rotating plate. The plurality of grids can pass between the transmitting end and the receiving end in turn.
[0010] As an improvement to the above solution, a reinforcing plate is provided on the side of the rotating component away from the rotating plate. The length direction of the reinforcing plate is arranged along the circumferential direction of the rotating component, and the side of the reinforcing plate can be connected to the side of multiple tooth blocks simultaneously.
[0011] As an improvement to the above solution, the number of reinforcing plates is multiple and they are evenly distributed along the circumference of the rotating component.
[0012] As an improvement to the above solution, the sensing element is a photoelectric sensor.
[0013] This utility model also provides a cold drink device, including the driving device described above.
[0014] Implementing this utility model has the following beneficial effects:
[0015] This utility model's drive device includes a drive component, a rotating component, and a transmission shaft. The transmission shaft is connected to the evaporator. The drive component can drive the transmission shaft to rotate through the rotating component. In order to monitor the rotation of the rotating component, a sensor is provided on the side of the rotating component. The sensor can detect the rotation speed of the rotating component. By comparing it with the motor speed, it can be detected whether the rotating component is rotating synchronously with the drive component. If asynchrony occurs, it indicates that there is a transmission failure such as the rotating component freezing. The machine can be stopped and inspected in advance before damage occurs, thus avoiding subsequent abnormal damage. Attached Figure Description

[0018] Figure 3 This is a schematic diagram of the rotating component of this utility model. Detailed Implementation
[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0020] See Figure 1 and Figure 2 This utility model discloses a driving device, including a driving component 1, a rotating component 2 connected to the driving component 1, and a transmission shaft 3 connected to the rotating component 2. The transmission shaft 3 is connected to the evaporator, and the driving component 1 can drive the transmission shaft 3 to rotate through the rotating component 2. A sensor 4 is provided on the side of the rotating component 2. The sensor 4 can detect the rotation speed of the rotating component 2. By comparing the conversion with the motor speed, it can be detected whether the rotating component 2 rotates synchronously with the driving component 1. During ice making, when ice forms around the evaporator, causing an increase in the resistance torque of the rotating component 2, the actual rotation speed of the rotating component 2 will lag behind the output speed of the driving component 1. This indicates that the rotating component 2 is abnormal, which may be due to the evaporator being frozen or ice accumulation affecting rotation, or it may be due to an abnormality in the transmission structure. This implementation method can identify abnormalities before the ice layer completely freezes the drive shaft 3 by monitoring the rotation speed synchronization. This is earlier than the action time of protection triggered by the evaporator temperature threshold in traditional antifreeze control. It can perform shutdown detection in advance before damage occurs, which can avoid motor overload or mechanical structure damage caused by sudden increase in transmission resistance.
[0021] The beneficial effects of this utility model embodiment are as follows:
[0022] This utility model embodiment of the driving device includes a driving component 1, a rotating component 2, and a transmission shaft 3. The transmission shaft 3 is connected to the evaporator. The driving component 1 can drive the transmission shaft 3 to rotate through the rotating component 2. In order to monitor the rotation of the rotating component 2, a sensor 4 is provided on the side of the rotating component 2. The sensor 4 can detect the rotation speed of the rotating component 2. By comparing it with the conversion of the motor speed, it can be detected whether the rotating component 2 rotates synchronously with the driving component 1. Once asynchrony occurs, it indicates that there is a transmission failure such as the rotating component 2 freezing. The machine can be stopped and inspected in advance before damage occurs, thus avoiding subsequent abnormal damage.
[0023] A transmission belt 5 is also provided between the driving component 1 and the rotating component 2. The transmission belt 5 is wound between the rotating end of the driving component 1 and the rotating component 2. The transmission belt 5 adopts a synchronous belt or V-belt structure, and its inner surface forms a closed loop with the driving wheel of the driving component 1 and the rotating component 2. The driving component 1 can drive the rotating component 2 to rotate through the transmission belt 5. Compared with the traditional gear direct drive method, this embodiment transmits power through a flexible transmission belt 5, which can buffer the instantaneous impact load when the motor starts and stops, and reduce the probability of monitoring signal distortion caused by sudden torque changes in the rotating component 2.
[0024] The rotating component 2 has multiple toothed blocks 21 on its circumference. The inner side of the transmission belt 5 can mesh with the toothed blocks 21, and the transmission belt 5 drives the rotating component 2 to rotate through the toothed blocks 21. When the evaporator is frozen or there is ice accumulation on its periphery affecting rotation, the toothed blocks 21 may cause abrasion to the internal teeth of the transmission belt 5, thereby affecting the subsequent transmission efficiency and further causing the actual rotational speed of the rotating component 2 to lag behind the output speed of the drive component 1.
[0025] The driving device also includes a rotating plate 6, which is fixed to one side of the rotating component 2 and arranged along the circumferential edge of the rotating component 2. The rotating plate 6 and the rotating component 2 are coaxially connected and fixed. The rotating plate 6 is provided with multiple grids 61, which are evenly distributed along the circumference of the rotating component 2. The grids 61 of the rotating plate 6 are arranged at equal angular intervals to form a periodic light-transmitting structure. The alternating distribution of the solid parts and hollow areas of the grids 61 can generate a regular pulse signal sequence when the rotating component 2 rotates.
[0026] The driving device also includes a fixing frame 7, which is fixed to the side of the rotating member 2. The sensor 4 is mounted on the fixing frame 7 and located on the side of the rotating plate 6. The sensor 4 can detect the grid 61. The fixing frame 7 is connected to the side wall of the rotating member 2 by a rigid bracket. The sensor 4 is fixed to one side of the fixing frame 7 by bolts or other fasteners. The detection direction of the sensor 4 is perpendicular to the rotation plane of the rotating plate 6 to ensure the stability of the signal amplitude when the grid 61 passes through.
[0027] The sensing element 4 is a photoelectric sensor, which adopts a transmission or reflection detection principle. Its optical path axis is orthogonal to the movement trajectory of the grid 61. When the solid part of the grid 61 blocks the light path, the sensor outputs a high-level signal; when the hollow area allows light to pass through, it outputs a low-level signal, forming a square wave pulse sequence that strictly corresponds to the rotational speed of the rotating part 2. The sensing element 4 is fixed to the side of the fixing frame 7. The sensing element 4 includes a transmitter 41 and a receiver 42. The transmitter 41 and the receiver 42 are infrared through-beam sensors. The transmitter 41 and the receiver 42 extend towards the inside of the rotating part 2 and are located on both sides of the rotating plate 6, respectively. Multiple grids 61 can pass between the transmitter 41 and the receiver 42 in turn. When the solid part of the grid 61 blocks the light beam of the transmitter 41, the receiver 42 outputs a high level; when the hollow area allows the light beam to pass through, the receiver 42 returns to a low level. By counting the number of high and low level switching times per unit time, the real-time rotational speed of the rotating part 2 can be calculated.
[0028] See Figure 3 A reinforcing plate 22 is provided on the side of the rotating component 2 away from the rotating plate 6. The length direction of the reinforcing plate 22 is arranged along the circumference of the rotating component 2, and the side of the reinforcing plate 22 can be connected to the side of multiple tooth blocks 21 simultaneously. The reinforcing plate 22 extends along the circumference of the rotating component 2, and its side is connected to the root of the tooth block 21 by welding or integral molding to form a continuous reinforcing ring structure around the rotating component 2. The reinforcing plate 22 evenly transmits the lateral load of multiple independent tooth blocks 21 to the body of the rotating component 2, suppressing the bending stress concentration phenomenon generated at the root of the tooth block 21 during the meshing of the transmission belt 5. On the one hand, it can avoid the failure of the tooth block 21, and on the other hand, it can avoid the problem of tooth skipping or meshing failure of the transmission belt 5 due to local deformation of the tooth block 21, ensuring the continuity of the speed monitoring signal.
[0029] The number of reinforcing plates 22 is multiple and they are evenly distributed along the circumference of the rotating component 2. Each reinforcing plate 22 covers the connection area of 3-8 adjacent tooth blocks 21.
[0030] This utility model embodiment also discloses a cold drink device (not shown in the accompanying drawings), including the driving device described above. The cold drink device is used for making ice, shaved ice, and other cold drinks. The driving device includes a driving component 1, a rotating component 2, and a transmission shaft 3. The transmission shaft 3 is connected to the evaporator. The driving component 1 can drive the transmission shaft 3 to rotate via the rotating component 2. To monitor the rotation of the rotating component 2, a sensor 4 is provided on the side of the rotating component 2. The sensor 4 can detect the rotation speed of the rotating component 2. By comparing this speed with the motor speed, it can be detected whether the rotating component 2 rotates synchronously with the driving component 1. If asynchrony occurs, it indicates a transmission malfunction such as the rotating component 2 freezing. This allows for early shutdown and inspection before damage occurs, thus preventing subsequent abnormal damage.
[0031] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
