[0022] The technical scheme of the utility model will be further specifically explained below through embodiments and in combination with the drawings.

[0023] Embodiment one:

[0024] Screw counting device is a widely used metering and monitoring equipment, widely used in industrial production, scientific research and daily life and other fields. With the rapid development of modern production and research, the role of counting device is increasingly significant, especially in the scene of high precision, high efficiency metering, screw counting device has been widely used and promoted due to its unique structure and working principle. In industrial production, the main function of screw counting device is to accurately measure the quantity of materials, and can monitor and adjust the production process, and to a certain extent, realize the control of automatic equipment. The measurement range of this device is very wide, which can be applied to the measurement of powders, particles, liquids and other materials. For example, in the chemical industry, screw counting device can be used for accurate measurement of chemical raw materials, so as to ensure the stability of chemical reaction and the quality of products; In the food processing industry, this device can be used for quantitative distribution of various raw materials to ensure the accuracy of proportioning in food production process, so as to improve the taste and safety of products; In the pharmaceutical industry, screw counting device also plays an important role. Through accurate counting of drug raw materials or finished products, the accuracy of drug dosage can be ensured, and the efficacy and safety of drugs can be ensured.

[0025] However, although screw counting device plays an important role in industrial production and scientific research, there are still some problems to be solved in practical application. For example, in the scene of high precision measurement, if the design of the device is not exquisite enough, it may cause counting error accumulation, which will affect the final measurement result; When dealing with high viscosity or irregular particle materials, screw counting device may face the problems of blockage or sliding, which will affect the working efficiency of the device; In addition, on some high-speed production lines, if the response speed of the counting device is not enough, it may not meet the high efficiency operation demand of the production line. The existence of these problems shows that further optimizing the design of screw counting device, improving its measurement precision and efficiency, is the key direction of current related field research.

[0026] In view of the above problems, the utility model provides an improved screw counting device to meet the demand of modern production and scientific research for high precision measurement, including workbench 1 and motor 2, wherein, motor 2 is connected on one side of workbench 1 through fixed plate, to ensure the stability of the whole device, workbench 1 is equipped with through slot, the main function of through slot is to provide installation space for counting mechanism channel 3, through slot is equipped with counting mechanism channel 3, counting mechanism channel 3 is the core part of the device, which is used for realizing accurate counting of materials. A plurality of cups 4 are arranged in the counting mechanism channel 3.

[0027] To further improve the accuracy of counting, in actual application, the device can also be equipped with photoelectric sensors or other types of detection equipment for real-time monitoring of the movement state and counting of the material. Once the counting is abnormal, the device can issue an alarm or automatically adjust the working state through the built-in control system, thereby ensuring the stability and reliability of the counting process.

[0028] In addition, in order to adapt to the metering needs of different materials, the device can also adjust the diameter, pitch of the screw and the capacity of the cup 4 according to the properties of the material. For example, for materials with larger particles, a screw with larger diameter and pitch can be selected to reduce the risk of blockage; for materials with poor flowability, the smoothness of the screw surface can be optimized to improve the conveying effect of the material. This flexible design enables the screw counting device to be applicable to a wider range of application scenarios, thereby further expanding its range of use.

[0029] The upper half of the workbench 1 is isosceles trapezoidal in shape, which has certain stability and practicality in industrial equipment and can adapt to various working scenarios and meet different production needs. Specifically, the isosceles trapezoidal design not only enhances the rigidity and load-bearing capacity of the workbench 1, but also provides more space and convenience for subsequent equipment installation and operation. The workbench 1 is centrally provided with a point counting screw 5 on one side of the upper end, which is a very critical structural component. The presence of the point counting screw 5 is mainly to achieve precise counting or positioning during device operation, and its position is carefully considered to ensure optimal performance in the overall structure of the workbench 1. The installation position of the point counting screw 5 not only requires to be centered, but also needs to be well coordinated with the overall design of the workbench 1 to provide more stable and precise support during production and processing.

[0030] Below the point counting screw 5 is a support roller group that provides stable support and transmission functions for the operation of the device. The support roller group includes first and second support rollers 6 and 7 arranged symmetrically on the left and right, which effectively balances the stress on the workbench 1 during operation, thereby improving the stability and durability of the device operation. The distance and angle between the first and second support rollers 6 and 7 are carefully calculated and designed to ensure that they work together to complete the support and transmission tasks.

[0031] The first support roller 6 is provided with a sensing point that can sense the position, state or operation of different objects on the workbench 1 in real time through cooperation with other equipment, thereby providing reliable data support for subsequent automated control.

[0032] The workbench 1 also has a proximity switch 8 on one side. The proximity switch 8 is a common but very important industrial sensor, whose main function is to detect the approach or departure of objects in real time. The presence of the proximity switch 8 makes the entire workbench 1 more intelligent and perceptive, and can achieve more precise control and operation through the signal feedback of the proximity switch 8 in production operations.

[0033] The proximity switch 8 is fixed on the surface of the workbench 1 through a connecting piece, which ensures the firmness of the installation of the proximity switch 8 and also provides convenience for subsequent maintenance and replacement. The selection and design of the connecting piece are also carefully selected to ensure stability during long-term use and not easily affected by external environments such as vibration, temperature changes, or humid environments.

[0034] When an object on the workbench 1 approaches the proximity switch 8, the proximity switch 8 can immediately perceive this change and transmit a signal to the control system, which further adjusts the operating state of the workbench 1 according to the received signal. At the same time, the point screw 5 can also count or position the object through a pre-set program, and this multi-component cooperative working method greatly improves the automation level and operating efficiency of the workbench 1.

[0035] The point screw 5 is provided with a threaded groove, and the point mechanism channel 3 is provided with an opening.

[0036] The threaded groove is in contact with the cup 4 through the opening.

[0037] The point screw 5 and the support roller group are equipped with synchronous pulleys 9 on the other side of the workbench 1, and the synchronous pulleys 9 are connected with the motor 2 through synchronous belts 10.

[0038] The specific shape, depth, and pitch of the threaded groove are designed according to the working requirements of the point mechanism. The main function of the threaded groove is to complete the point operation through contact with the cup 4. During the entire point process, the cup 4 moves through the point mechanism channel 3, and the channel is provided with an opening. The function of this opening is to enable the threaded groove to directly contact the cup 4, thereby realizing the point function. The design of the point mechanism channel 3 is also very important. The width and height of the channel, as well as the size and position of the opening, need to be accurately calculated to ensure that the cup 4 can smoothly pass through and also effectively contact the threaded groove. The shape of the opening may be rectangular, arc-shaped, or other shapes, depending on the specific design requirements and the shape and size of the cup 4.

[0039] Another major feature of the point screw 5 is its linkage design with the supporting roller group. On the other side of the workbench 1, both the point screw 5 and the supporting roller group are equipped with synchronous pulleys 9. The advantage of this design is that the synchronous operation of the two can be achieved through the synchronous belt 10. The selection of the synchronous pulley 9 and the synchronous belt 10 is very critical, as the synchronous belt 10 needs to have sufficient strength and wear resistance, while also needs to have a certain flexibility to adapt to various dynamic loads during the operation of the equipment. The motor 2 is the power source of the entire system, through the drive of the motor 2, the synchronous belt 10 drives the synchronous pulley 9 to rotate, thereby realizing the linkage of the point screw 5 and the supporting roller group. The selection of the motor 2 needs to consider multiple factors, such as whether its power is sufficient, whether its speed can meet the requirements, whether it has high efficiency, and whether it has stability and reliability during operation.

[0040] The use of synchronous pulleys 9 and synchronous belts 10 enables the point screw 5 and the supporting roller group to achieve highly synchronized operation. This synchronization is crucial for the normal operation of the entire equipment. If the point screw 5 and the supporting roller group are not synchronized, it may cause the items to shift, jam or even be damaged during the counting process. In order to ensure the long-term stable operation of the synchronous belt 10, it needs to be regularly inspected and maintained. For example, it needs to be checked whether the synchronous belt 10 has wear, cracks or slack, and if problems are found, it needs to be replaced or adjusted in time. In addition, the tooth shape design of the synchronous pulley 9 also needs to be completely matched with the synchronous belt 10, in order to avoid slipping or poor engagement during operation.

[0041] The motor 2, as the power source of the entire system, its operating state directly determines the working efficiency and stability of the equipment. The selection of the motor 2 needs to be determined according to the specific needs of the equipment, such as the counting speed, the weight of the items and the operating environment, etc. In some high-precision applications, it may be necessary to use a servo motor 2 or a stepper motor 2 to achieve higher control accuracy. At the same time, the motor 2 also needs to be equipped with appropriate drivers and control systems, so as to be able to adjust the operating parameters according to the actual needs. For example, the speed of the motor 2 can be adjusted through the control system, so as to change the rotation speed of the point screw 5, to adapt to the counting needs of different items.

[0042] In the actual application of the point screw 5 and the counting mechanism, its design and operation also need to consider multiple details. For example, the machining precision of the thread groove directly affects the accuracy of the counting, therefore, advanced machining processes and equipment need to be used to ensure its precision. At the same time, strict quality detection needs to be carried out on the equipment, such as detecting the size of the thread groove through a three-coordinate measuring instrument, to ensure that it meets the design requirements. In addition, during the operation of the equipment, regular lubrication and maintenance of the point screw 5, the supporting roller group and the synchronous pulley 9, etc. parts need to be carried out, in order to prolong its service life and improve the reliability of the equipment.

[0043] Example Two:

[0044] Operation Principle:

[0045] The cups 4 are continuously fed into the counting mechanism's channel, achieving accurate counting of the number of cups 4. The core part of the counting mechanism includes the counting screw 5, the first support roller 6, and the second support roller 7. These three components are connected to the motor 2 through a synchronous belt 10, ensuring synchronous rotation between the three axes. Due to the synchronous rotation of the three axes, the entire transmission system can effectively drive the cups 4 to rotate simultaneously, keeping the cups 4 in a stable rotating state during transportation and counting. An important advantage of this design is that it significantly reduces the friction between the cups 4 and the rollers, thereby reducing mechanical wear and tear and increasing the service life of the equipment. In addition, this friction-reducing design can effectively prevent the cups 4 from slipping or deviating during transportation, further improving the accuracy of counting.

[0046] The design of the counting screw 5 is the key to the system. The screw surface is designed with precise spiral groove structures that closely match the cups 4 through optimized design for the specifications of the cups 4. Through this precise matching, only one cup 4 is allowed to pass through the spiral groove when the counting screw 5 rotates one revolution. This "one cup per revolution" design ensures that there is no undercounting or repeated counting during the counting process, thereby achieving accurate control of the number of cups 4.

[0047] During the counting process, the first support roller 6 and the second support roller 7 not only support and transport the cups 4, but also record the number through cooperation with the proximity switch 8. The first support roller 6 is pre-set with a sensing point. When the roller completes a full rotation, the sensing point passes through the sensing area of the proximity switch 8, triggering the proximity switch 8 to send a signal. Each time the proximity switch 8 senses, it is equivalent to recording the passage of a cup 4, so the total number of cups passing through can be calculated by the number of rotations of the roller.

[0048] The entire system is driven by the motor 2, combined with synchronous belt 10 transmission, spiral groove precise design, and proximity switch 8 sensing technology, through highly coordinated actions, achieving accurate counting of the number of cups 4. This design not only meets the counting needs of cups of different specifications, but also can control the speed of the conveyor belt by adjusting the motor 2 speed, adapting to the operation rhythm of different production lines. At the same time, since the counting process is fully automated, it significantly improves production efficiency and reduces the complexity and error rate of manual operation.
