Description

Technical Field

[0001] The utility model relates to the technical field of packaging machines, in particular to a particle packaging machine. Background Art

[0002] Granule packaging machines are widely used in the packaging of granular items. They use the coherent operation of the equipment mechanism to package granular products in quantitative bags for easy transportation and storage. The cutting of existing granule packaging machines generally uses the photoelectric sensor on the packaging machine to identify the trigger end on the packaging bag, identify the model of the packaging bag, and then seal and cut according to the bag length of this model of packaging bag. However, dust easily accumulates at the photoelectric sensor, which affects the recognition.

[0003] Some granule packaging machines, such as the Chinese patent authorization announcement number CN104760717A, named "A granule material packaging machine", include a vertical frame, a coil conveying device, a feeding device, a bag forming device and a sealing device; the sealing device includes a longitudinal sealing traction device and a transverse sealing cutting device; the longitudinal sealing traction device is arranged above the transverse sealing cutting device. The disadvantage is that the photoelectric sensor is used to sense the trademark pattern information on the packaging film, but dust is easily accumulated at the photoelectric sensor, which leads to a decrease in the accuracy and sensitivity of the packaging bag recognition. Utility Model Content

[0004] Aiming at the problem that dust is easily accumulated at the photoelectric sensor of the current granule packaging machine, resulting in reduced accuracy and sensitivity of packaging bag recognition, the utility model proposes a granule packaging machine which can remove dust accumulation at the photoelectric sensor and improve the accuracy and sensitivity of sensing.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a particle packaging machine, including a fixed bracket and a photoelectric sensor for sensing the position and model of a packaging bag, the packaging bag is provided with a trigger end for identifying the model of the packaging bag, the trigger end is adapted to the photoelectric sensor, the packaging bag can be raised and lowered relative to the fixed bracket, the particle packaging machine also includes a blowing part, the blowing part is provided with a blowing port facing the photoelectric sensor, so as to blow away the accumulated dust at the photoelectric sensor.

[0006] In this technical solution, the photoelectric sensor senses the trigger end, thereby identifying the position and model of the packaging bag. The trigger end rises and falls with the packaging bag, which makes it easier for the photoelectric sensor to identify the position and model information of the packaging bag in turn. The air blowing port is set to face the photoelectric sensor, which can effectively blow away the dust accumulated on the surface of the photoelectric sensor, improve the sensing accuracy and sensitivity of the photoelectric sensor, and prevent dust from interfering with its normal operation. By reducing the misreading or failure of the photoelectric sensor due to dust accumulation, the blowing part helps to improve the overall reliability and stability of the packaging machine. The packaging machine can more accurately identify and sense the position and model of the packaging bag to ensure that each packaging bag can be handled correctly. Due to the improved accuracy of the photoelectric sensor, the packaging machine can identify and locate the packaging bag more quickly, thereby speeding up production, reducing downtime or erroneous operation caused by sensor misreading, and further improving production efficiency. By automatically cleaning dust regularly, the blowing part also helps to extend the service life of the photoelectric sensor. Keeping the sensor clean can reduce the risk of wear and damage, thereby ensuring the long-term stable operation of the packaging machine.

[0007] The utility model is further configured as follows: the blowing part includes a pump body for generating and driving an airflow, an air pipe assembly connected to the pump body, and a valve body assembly installed on the air pipe assembly, wherein the air pipe assembly is used to transmit the airflow generated by the pump body and guide the airflow to the air outlet for discharge, and the valve body assembly is used to switch the on-off state of the air pipe assembly. Through this configuration, the pump body can effectively generate and drive the airflow, ensuring sufficient airflow supply. The air pipe assembly is used to efficiently transmit the airflow generated by the pump body to the air outlet, ensuring the working efficiency of the blowing part. The design of the valve body assembly enables the on-off state of the air pipe assembly to be flexibly switched, so that the blowing part can accurately control the on-off of the airflow as needed, which not only saves energy but also avoids unnecessary waste of airflow. By accurately controlling the on-off of the airflow, the blowing part can provide a strong airflow when needed, thereby more effectively blowing away the dust on the photoelectric sensor, keeping the sensor clean, and improving its sensing accuracy. The blowing part is more systematic, and each component has its specific function, which is convenient for installation, debugging and maintenance.

[0008] The utility model is further configured as follows: the blowing part includes an air pipe assembly for transmitting gas and an elastic blowing ball, and the blowing ball is connected to the air pipe assembly. When the blowing ball is compressed and deformed, the gas in the blowing ball can be discharged from the blowing port through the air pipe assembly. Through this configuration, the gas can be easily discharged by pressing the blowing ball, without the need for a complex control mechanism or power drive. The compression deformation of the blowing ball can immediately trigger the discharge of the gas, providing instant feedback. At the same time, by controlling the degree of pressure on the blowing ball, the amount and speed of gas discharge can be accurately adjusted. It does not rely on electricity or other external energy sources to drive the gas flow, so it does not generate additional energy consumption during operation, which is in line with the concept of energy saving and environmental protection.

[0009] The utility model is further configured as follows: the air blow port is arranged between the photoelectric sensor and the packaging bag to prevent the airflow discharged from the air blow port from affecting the packaging bag. By arranging the air blow port between the photoelectric sensor and the packaging bag, the airflow discharged from the air blow port can be effectively prevented from blowing directly to the packaging bag, thereby avoiding the possible interference of the airflow on the packaging bag, such as displacement and deformation. The photoelectric sensor can more accurately detect the position, model and other information of the packaging bag without the interference of the airflow, which helps to improve the overall performance and accuracy of the packaging machine and ensure that each packaging bag can be correctly identified and positioned. The packaging machine can operate in a more stable and reliable environment, reducing the downtime caused by the displacement or damage of the packaging bag, thereby improving the overall production speed and efficiency.

[0010] The utility model is further configured as follows: the blowing part is arranged in the blowing area, and the blowing area avoids the direct connection line between the photoelectric sensor and the trigger end, so as to ensure that the blowing part does not block the normal recognition of the trigger end by the photoelectric sensor. Through this configuration, it is ensured that the photoelectric sensor can recognize the trigger end without obstacles, so as to accurately recognize the model and position of the packaging bag. The blowing part does not block the line of sight of the photoelectric sensor, and the packaging machine does not need to perform additional adjustment or compensation operation when working, thereby improving the working efficiency of the entire packaging process. In addition, the possibility of misidentification and repeated identification is reduced, and the production speed is further accelerated.

[0011] The utility model is further configured as follows: a windshield is provided on the outside of the air outlet, and the opening of the windshield gradually increases from the air outlet to the outside. Through this configuration, the blown airflow is effectively guided and diffused to avoid excessive concentration of the airflow or the formation of a strong airflow impact. The design of the windshield helps to reduce the interference of the airflow blown out of the air outlet on the external environment. The airflow is spread through the gradually increasing opening, which reduces the impact on peripheral equipment or operations and improves the stability of the overall working environment.

[0012] The utility model is further configured as follows: the particle packaging machine also includes a longitudinal vertical sealing part and a transverse packaging part cooperating with the longitudinal vertical sealing part, the longitudinal vertical sealing part is used to vertically seal the side of the packaging bag filled with particles, and the transverse packaging part is used to transversely seal the top or bottom of the packaging bag while the longitudinal vertical sealing part vertically seals the side of the packaging bag. Through this configuration, the particle packaging machine realizes efficient packaging of the packaging bag through the coordinated work of the longitudinal vertical sealing part and the transverse packaging part. The transverse packaging part can transversely seal the top or bottom of the packaging bag while the longitudinal vertical sealing part vertically seals the side of the packaging bag, thereby improving production efficiency. The automated coordination of the longitudinal vertical sealing part and the transverse packaging part reduces the intervention of manual operation and improves the automation level of the production process. It can flexibly adapt to packaging bags of different specifications and sizes, providing greater flexibility for production companies and meeting the diversified needs of the market.

[0013] The utility model is further configured as follows: the particle packaging machine also includes a transverse cutting part for cutting the packaging bags after transverse packaging, so as to separate the continuously packaged packaging bags into single independent packaging units. Through continuous packaging and subsequent cutting, the particle packaging machine can achieve efficient continuous production. The existence of the transverse cutting part allows the continuously packaged packaging bags to be quickly and accurately separated into single independent packaging units, thereby greatly improving production efficiency. The automated transverse cutting part reduces the need for manual cutting, reduces labor costs, and avoids errors and inconsistencies that may be caused by manual operation. The automated cutting process reduces the direct contact between the operator and the cutting tool, thereby reducing safety risks during the work process.

[0014] The utility model is further configured as follows: the valve body assembly is a solenoid valve. As a valve body assembly, the solenoid valve can provide accurate and fast airflow control. The solenoid valve has a fast response speed and can quickly switch the on and off state of the air pipe assembly to ensure that the blowing part can immediately provide or cut off the airflow when needed. The solenoid valve can be seamlessly integrated with the control system of the packaging machine to achieve automatic control.

[0015] The utility model is further configured as follows: the photoelectric sensor is a photoelectric induction switch, and the trigger end is a positioning cursor. As a photoelectric sensor, the photoelectric induction switch has high sensitivity and accuracy, and can effectively detect the positioning cursor as the trigger end, ensuring that the packaging machine can accurately identify the position and state of the packaging bag, and provide accurate data support for the subsequent packaging process. The photoelectric induction switch has a fast response speed, and when the positioning cursor passes by, it can quickly send a signal, so that the packaging machine can adjust the working state in real time and improve production efficiency.

[0016] The advantages of the utility model are: (1) it can remove dust accumulation at the photoelectric sensor and improve the accuracy and sensitivity of sensing; (2) by reducing the misreading or failure of the photoelectric sensor caused by dust accumulation, the blowing part helps to improve the overall reliability and stability of the packaging machine, and the packaging machine can more accurately identify and sense the position and model of the packaging bag to ensure that each packaging bag can be properly processed; (3) by automatically cleaning dust regularly, the blowing part also helps to extend the service life of the photoelectric sensor.
