[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] In order to solve the problem that the accumulated chips at the transmission mechanism of the chip conveyor in the prior art are difficult to clean, the present invention provides a chip conveyor and an air blowing control method thereof.

[0026] Please refer to Figures 1 to 4 As shown, one aspect of the technical solution of the present invention provides a chip conveyor, including a machine body 10, an air blowing pipe 20, a valve assembly and a control unit; the air blowing pipe 20 is rotatably arranged on the machine head 11 of the machine body 10, and the air blowing pipe 20 is provided with a plurality of groups of air blowing holes 21 at intervals along its extension direction, each group of air blowing holes 21 includes a plurality of air blowing holes 21 arranged at intervals, and the opening of each air blowing hole 21 is arranged toward the transmission mechanism in the machine head 11; one end of the valve assembly is connected to one end of the air blowing pipe 20, and the other end of the valve assembly is used to be connected to an external air source for providing gas to the air blowing pipe 20; the control unit is connected to the air blowing pipe 20 for respectively controlling the air blowing volume, air blowing speed and rotation speed of the air blowing pipe 20.

[0027] One aspect of the technical solution of the present invention is to set a rotatable air blowing pipe 20 in the position facing the transmission mechanism in the machine head 11, and a plurality of air blowing holes 21 evenly distributed along its length direction, so as to ensure the uniformity of the air flow, and then effectively blow away the accumulated chips around the transmission mechanism, avoiding the complexity and inefficiency of the traditional cleaning method, and solving the problem that the accumulated chips at the transmission mechanism of the chip conveyor in the prior art are difficult to clean. In addition, the control unit can automatically adjust the air volume, air speed and rotation speed of the air blowing pipe 20 according to the amount of waste chips at the transmission mechanism, which makes the waste chip cleaning process more intelligent, can be adjusted in real time according to actual needs, and improves the accuracy and efficiency of cleaning. Through regular and intelligent air blowing cleaning, the accumulation of waste chips on the transmission mechanism can be reduced, thereby reducing the wear of key components such as gears and bearings, extending the service life of the chip conveyor and the transmission mechanism, and reducing the frequency of maintenance and repair.

[0028] In the present embodiment, each of the blowing holes 21 is a circular hole, and the diameter of each of the blowing holes 21 ranges from 3 mm to 7 mm. In this way, the circular hole design can make the airflow more concentrated, forming a stronger blowing airflow, which helps to more effectively remove fine waste debris near the transmission mechanism and reduce the deposition of waste debris on key components. By uniformly distributing each group of blowing holes 21 on the blowing pipe 20, the circular holes can ensure the uniformity of the airflow, avoiding poor local cleaning effects or damage caused by excessive blowing due to uneven airflow distribution. Compared with strip holes or holes of complex shapes, circular holes have less friction when gas passes through at the same opening area, thereby reducing the energy loss of the airflow and improving the gas utilization efficiency.

[0029] Optionally, each of the air blowing holes 21 is a strip hole, the opening length of each air blowing hole 21 ranges from 5mm to 9mm, and the opening width of each air blowing hole 21 ranges from 3mm to 7mm. In this way, the airflow intensity and distribution can be adjusted by adjusting the size of the air blowing holes 21, so as to achieve more precise control of the blowing volume and blowing speed, and adapt to the requirements for cleaning effect under different working conditions. Compared with circular holes, strip holes can provide a larger coverage area with less airflow loss, so that the airflow can cover various parts of the transmission mechanism more widely, and improve the efficiency and uniformity of blowing away waste chips. It can thus better adapt to waste chips of different shapes and sizes, especially when dealing with long strips or thin sheets of waste chips, the long strip airflow can more effectively blow them away from the transmission mechanism, reducing the risk of waste chips getting stuck.

[0030] Optionally, each blowing hole 21 includes at least two arc-shaped hole segments connected in sequence, and the diameter of the circle where each arc-shaped hole segment is located ranges from 0.5 mm to 1 mm. In this way, it can better adapt to the waste chips of different shapes and sizes accumulated in the transmission mechanism, especially for those small waste chips that are easily stuck in complex structures, the arc-shaped airflow can blow them out more effectively. In addition, the composition of at least two hole segments can effectively prevent the waste chips from clogging the blowing hole 21 or entering the blowing pipe 20 from the blowing hole 21 when cleaning the waste chips. Compared with large-diameter circular or bar holes, small-diameter arc-shaped hole segments generate lower noise when gas flows, which improves the comfort of the working environment.

[0031] In this embodiment, a plurality of the blowing holes 21 in each group of the blowing holes 21 are arranged at intervals along the circumferential direction of the blowing pipe 20 or are arranged in a spiral line along the extension direction of the blowing pipe 20. In this way, when the blowing holes 21 are arranged at intervals along the circumferential direction, it can be ensured that when the blowing pipe 20 rotates, the airflow can evenly cover the entire outer surface of the transmission mechanism, achieve all-round blowing, and effectively remove waste debris in all directions. When the blowing holes 21 are arranged in a spiral line along the extension direction of the blowing pipe 20, as the blowing pipe 20 rotates, the airflow will deeply clean the transmission mechanism along the spiral path. This design can more deeply blow away the waste debris inside the transmission mechanism and avoid the accumulation of waste debris inside. Whether it is arranged at intervals circumferentially or in a spiral line, it can significantly reduce the cleaning blind area around the transmission mechanism, ensure that every corner can be covered by the airflow, and improve the thoroughness and uniformity of the cleaning. Different arrangements can be selected according to the specific shape of the transmission mechanism and the distribution characteristics of the waste chips, so that the air blowing pipe 20 can more effectively adapt to different working conditions and improve the cleaning efficiency.

[0032] In this embodiment, the diameter of the blowing pipe 20 ranges from 6mm to 10mm; the length of the blowing pipe 20 ranges from 300mm to 700mm. In this way, the blowing pipe 20 can provide sufficient airflow channels to ensure smooth airflow and reduce resistance during gas delivery, thereby improving gas delivery efficiency and blowing effect, while having a certain structural strength. The blowing pipe 20 can also adapt to transmission mechanisms of different sizes and layouts to ensure that the key areas of the entire transmission mechanism are covered. Whether it is a small transmission system or a large and complex mechanical structure, effective cleaning can be achieved by adjusting the length of the blowing pipe 20. By optimizing the size of the blowing pipe 20, unnecessary gas consumption can be effectively reduced, and precise control of the airflow can be achieved, thereby reducing overall energy consumption and improving energy utilization efficiency.

[0033] In this embodiment, the blowing pipe 20 is made of stainless steel. In this way, stainless steel has high strength and rigidity, so that the blowing pipe 20 can maintain its shape when subjected to external pressure and internal gas pressure, avoiding deformation that affects the distribution and control of airflow.

[0034] Specifically, the chip conveyor also includes a mounting joint, which is arranged on the head 11 of the machine body 10, one end of the air blowing pipe 20 is connected to the mounting joint, and the mounting joint is connected to the valve assembly through the air supply pipe, so that the valve assembly controls the amount of gas and the gas speed entering the air blowing pipe 20. In this way, by using the mounting joint in combination with the air supply pipe, the stability and uniformity of the gas during the transportation process from the external gas source to the air blowing pipe 20 can be ensured, leakage and pressure loss in the gas flow can be avoided, and the gas utilization efficiency can be improved. And the valve assembly can more accurately control the amount of gas and the gas speed entering the air blowing pipe 20, which can ensure that an efficient cleaning effect can be achieved under different working conditions.

[0035] Specifically, the chip conveyor also includes a driving component, which is arranged on the head 11 of the machine body 10, and the driving end of the driving component is connected to the end of the blowing pipe 20 away from the valve assembly, so as to drive the blowing pipe 20 to rotate. Among them, the driving component is a stepping motor, etc. In this way, the blowing pipe 20 can rotate while the airflow is blowing. This dynamic blowing method can more effectively cover the various surfaces of the transmission mechanism. Compared with static blowing, the cleaning effect is more thorough and can remove more difficult-to-reach waste chips. In addition, by controlling the rotation speed of the driving component, the rotation speed of the blowing pipe 20 can be adjusted, thereby optimizing the coordination of blowing and rotation, improving the speed and efficiency of cleaning waste chips, reducing unnecessary downtime, and improving overall production efficiency. When the amount of waste chips at the transmission mechanism is large, the rotation of the blowing pipe 20 can be accelerated and the blowing frequency can be increased; when the amount of waste chips is small, the rotation speed can be reduced, energy consumption can be reduced, and adaptive cleaning capabilities can be achieved.

[0036] Specifically, the control unit includes a detection sensor, a signal receiving module, a data processing module and a controller; the detection sensor is arranged on the head 11 of the machine body 10, and is used to monitor the amount of waste chips at the transmission mechanism in the head 11 in real time; the signal receiving module is connected to the detection sensor signal to receive the data detected by the detection sensor; the data processing module is connected to the signal receiving module signal to analyze the data received by the signal receiving module; the controller is respectively connected to the detection sensor, the signal receiving module, the data processing module signal, the valve assembly and the driving component to control the blowing volume, blowing speed and rotation speed of the blowing pipe 20 according to the analysis results of the data processing module.

[0037] Through the above-mentioned setting, the detection sensor can monitor the amount of waste chips at the transmission mechanism in the machine head 11 in real time, and immediately feedback data to the signal receiving module, which allows the control system to quickly respond to the current waste chip cleaning needs and improve the timeliness and effectiveness of cleaning. The data processing module analyzes and processes the received sensor data, can identify the changing trend of the amount of waste chips, and judge whether it is necessary to adjust the cleaning parameters. This precise data processing capability ensures that the control system can make accurate decisions and avoid unnecessary waste of resources. The controller automatically adjusts the opening of the valve assembly and the speed of the driving component according to the analysis results of the data processing module to achieve dynamic control of the blowing volume, blowing speed and speed of the blowing pipe 20. Automatic control reduces the complexity and error rate of manual operation and improves the overall efficiency and stability of the system. In addition, by real-time monitoring and dynamic adjustment of the blowing parameters, excessive blowing can be avoided when the amount of waste chips is small, energy consumption is reduced, and noise and environmental pollution are also reduced, reflecting the energy-saving and environmental protection design of the system.

[0038] Another aspect of the technical solution of the present invention provides an air blowing control method, which is applicable to the chip conveyor mentioned above. The air blowing control method includes: setting a preset waste chip amount threshold; obtaining the real-time waste chip amount at the transmission mechanism in the machine head 11 detected by the detection sensor; comparing the real-time waste chip amount with the preset waste chip amount threshold, and controlling the air blowing amount, air blowing speed and rotation speed of the air blowing pipe 20 respectively through the opening of the control valve assembly and the driving component according to the comparison result. In this way, by setting the preset waste chip amount threshold, the control system can dynamically adjust the air blowing parameters according to the actual waste chip amount, avoiding the situation of excessive air blowing or insufficient air blowing, and realizing the precise control of the cleaning operation. And adjusting the air blowing amount, air blowing speed and rotation speed according to the real-time waste chip amount can reduce energy consumption while ensuring the cleaning effect, avoid unnecessary waste of resources, and improve the overall energy efficiency of the system. The control method can be adaptively adjusted according to environmental changes, whether in the working condition of high waste chip amount or in the working condition of low waste chip amount, it can provide appropriate cleaning force, and enhance the flexibility and adaptability of the system. In addition, real-time monitoring and dynamic control ensure that the transmission mechanism is always in a clean state, reducing the impact of waste chips on transmission efficiency and improving the cleanliness and operating efficiency of the overall equipment.

[0039] Specifically, according to the comparison results, the opening of the control valve assembly and the driving component are respectively used to control the blowing volume, blowing speed and rotation speed of the blowing pipe 20, including: when the real-time waste volume is greater than or equal to the preset waste volume threshold, the opening of the control valve assembly is fully opened; when the real-time waste volume is less than the preset waste volume threshold, the opening of the control valve assembly is opened to a position of 2 / 3 opening. In this way, when the waste volume reaches or exceeds the preset threshold, the valve assembly opening is fully opened, which can provide maximum airflow, increase the blowing volume and blowing speed, so as to quickly and effectively clean up the accumulated waste, and prevent the transmission mechanism from being blocked and worn. When the waste volume is lower than the preset threshold, the valve assembly opening is only opened to 2 / 3 opening, which reduces the supply of airflow, avoids the use of excessive gas when the waste volume is small, achieves energy saving effect, and reduces operating costs. By real-time monitoring of the amount of waste chips and responding quickly, the air blowing control parameters are adjusted to improve the response speed of the system, which can immediately respond to changes in the amount of waste chips, keep the transmission mechanism clean, and improve the operating efficiency and stability of the chip conveyor. No human intervention is required, which improves the intelligence level of the system and reduces the workload of operators.

[0040] Specifically, according to the comparison results, the opening of the control valve assembly and the driving component are respectively used to control the blowing volume, blowing speed and rotation speed of the blowing pipe 20, including: when the real-time waste chip amount is greater than or equal to the preset waste chip amount threshold, the output shaft of the driving component is controlled to increase the rotation speed to 1.5 times the initial rotation speed; when the real-time waste chip amount is less than the preset waste chip amount threshold, the output shaft of the driving component is controlled to maintain the initial rotation speed. In this way, when it is detected that the waste chip amount reaches or exceeds the preset threshold, the rotation speed of the driving component is increased, which can significantly increase the rotation speed of the blowing pipe 20 and the blowing force of the airflow, thereby more effectively removing the waste chips at the transmission mechanism and preventing mechanical failures caused by waste chip accumulation. When the amount of waste chips is small, the initial rotation speed of the driving component is maintained, which avoids excessive energy consumption, realizes the effective use of energy, reduces the operating cost of the equipment, and also reduces unnecessary mechanical wear and noise. By adaptively adjusting the rotation speed of the driving component through real-time changes, the response speed and control accuracy of the system are improved, so that the chip conveyor can automatically optimize the cleaning strategy when facing different working environments, improve the adaptability and flexibility of the equipment, and thus improve production efficiency.

[0041] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0042] The chip conveyor includes a machine body 10, an air blowing pipe 20, a valve assembly and a control unit; the air blowing pipe 20 is rotatably arranged on the machine head 11 of the machine body 10, and the air blowing pipe 20 is provided with a plurality of groups of air blowing holes 21 at intervals along its extension direction, each group of air blowing holes 21 includes a plurality of air blowing holes 21 arranged at intervals, and the opening of each air blowing hole 21 is arranged toward the transmission mechanism in the machine head 11; one end of the valve assembly is connected to one end of the air blowing pipe 20, and the other end of the valve assembly is used to be connected to an external air source to provide gas to the air blowing pipe 20; the control unit is connected to the air blowing pipe 20 to respectively control the air blowing volume, air blowing speed and rotation speed of the air blowing pipe 20. In this way, by setting a rotatable air blowing pipe 20 in the position facing the transmission mechanism in the machine head 11, and a plurality of air blowing holes 21 evenly distributed along its length direction, the uniformity of the air flow can be ensured, and the accumulated chips around the transmission mechanism can be effectively blown away, thereby avoiding the complexity and inefficiency of the traditional cleaning method, and solving the problem that the accumulated chips at the transmission mechanism of the chip conveyor in the prior art are difficult to clean. In addition, the control unit can automatically adjust the air volume, air speed and rotation speed of the air blowing pipe 20 according to the amount of waste chips at the transmission mechanism, which makes the waste chip cleaning process more intelligent and can be adjusted in real time according to actual needs, thereby improving the accuracy and efficiency of cleaning. Through regular and intelligent air blowing cleaning, the accumulation of waste chips on the transmission mechanism can be reduced, thereby reducing the wear of key components such as gears and bearings, extending the service life of the chip conveyor and the transmission mechanism, and reducing the frequency of maintenance and repair.
