Description

Technical Field

[0001] This utility model relates to the field of electronic detonator electronic ignition module manufacturing technology, specifically an automatic drying device for the propellant head of an electronic ignition module. Background Technology

[0002] In the fields of military and civilian production technology, electronic ignition modules are key core components, and the safety, process precision, and production efficiency of their powder-dipping production process directly affect product quality and production benefits. Currently, with the increasing demand for industrial upgrading, enterprises are gradually promoting the automation technology transformation of powder-dipping production lines, aiming to replace the traditional manual operation mode with batch continuous automated production processes, fundamentally solving the inherent drawbacks of manual production. However, significant technical bottlenecks still exist in the existing production process. In the drying of the drug heads, the industry generally uses drying ovens or drying rooms, requiring manual transfer of the product to the drying area after the dipping process. During this manual transfer, the dipped drug solution has not yet solidified and is easily deformed, flowed, or even dripped due to gravity, vibration, and uneven handling. This directly leads to irregular shapes and large deviations in drug quantity after drying, making it difficult to guarantee product consistency. Manual transfer disrupts the continuity of the production process and increases external interference factors. Furthermore, the water-heating or hot air heating methods used suffer from uneven heat distribution and slow heating rates. These traditional heating methods require indirect heat transfer through air or other media, resulting in excessively long drying cycles. This not only reduces production efficiency but also may cause changes in the drug solution composition due to prolonged heating, further affecting product performance stability and hindering the improvement of overall process technology.

[0003] Chinese Patent Publication No. CN220852823U discloses a drying device for electronic detonator electronic ignition elements, including a frame. One side of the frame has a baffle plate with an inlet and an outlet. The bottom of the other side of the frame has a placement platform with an air duct inside. The top surface of the placement platform has an air outlet. A drying chamber is placed on the placement platform, and the lower part of the drying chamber has a hot air inlet that connects to the air outlet. Multiple windows are located on the side of the drying chamber near the baffle plate, and there are placement positions inside the drying chamber for connecting to these windows. A conveying device is installed inside the frame to transport the carrier from the inlet to the placement position and to output the carrier from the outlet. A recessed area is formed between the placement platform and the baffle plate to accommodate part of the conveying device. While this solution can dry electronic detonator electronic ignition elements with hot air, the drying chamber only receives hot air through a single hot air inlet, making heat loss during drying easy, hindering precise temperature control, and resulting in poor temperature uniformity across different areas, thus reducing drying efficiency. Utility Model Content

[0004] This utility model aims to provide an automatic drying device for the electronic ignition module propellant head, which effectively solves the problems in the prior art where the drying box only inputs hot air through a single hot air inlet, resulting in easy heat loss during the drying process, inability to accurately control the temperature, and poor temperature uniformity in different areas, thus reducing drying efficiency.

[0005] This application provides the following technical solution: An automatic drying device for electronic ignition module propellant heads includes a drying kiln, a conveying device, an infrared temperature control device, an exhaust device, and a conveying tray. The drying kiln includes a heating channel with an inlet and an outlet. The conveying device is disposed in the heating channel, with one end connected to the inlet and the other end connected to the outlet. The conveying tray is disposed on the conveying device, and the conveying device moves the tray along the heating channel during operation. The exhaust device is connected to the heating channel. The heating channel has multiple evenly distributed heating zones, each equipped with the infrared temperature control device.

[0006] The technical principle of this solution is as follows: When the automatic drying device for the electronic ignition module propellant head of this application is working, the transfer tray is placed on the transfer device, and the operation of the transfer device drives the transfer tray to move along the heating channel of the drying kiln from the inlet to the outlet. The heating channel has multiple evenly distributed heating zones, each equipped with an infrared temperature control device, which can independently and accurately control the temperature of each zone. At the same time, the exhaust device works to remove moisture and other air from the heating channel, maintaining a good drying environment. During the movement of the transfer tray, the electronic ignition module propellant head passes through different heating zones in sequence within the heating channel, achieving uniform and precise drying.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: Infrared radiation is used to heat the propellant head of the electronic ignition module, resulting in precise temperature control, rapid response, and no open flame or high-temperature airflow, thus minimizing the risk of ignition. Furthermore, the strong penetrating power of infrared radiation enables simultaneous drying of the propellant head both inside and out, improving drying quality. The transfer tray reduces wear on the mold storing the propellant head during repeated movement, extending its lifespan. The exhaust system effectively removes harmful gases generated during heating, preventing their accumulation and potential safety hazards. Multiple evenly distributed heating zones, each equipped with its own infrared temperature control device, are incorporated. Unlike existing drying ovens that rely on a single hot air inlet for precise temperature control, this infrared temperature control device precisely adjusts the temperature of each heating zone according to the drying requirements of the propellant head, preventing localized overheating or undercooling and ensuring accurate temperature control throughout the drying process, thereby improving drying quality.

[0008] Furthermore, the transmission device includes a transfer mechanism, which includes a first transfer mechanism. The heating channel has a U-shaped structure, with both the inlet and outlet of the heating channel located at one end of the drying kiln. The other end of the drying kiln is equipped with an openable and closable inspection door. Two conveyor lines are installed inside the heating channel, arranged side by side. The other end of the heating channel is connected to the two conveyor lines via the first transfer mechanism.

[0009] By designing the heating channel into a U-shape, the space utilization rate is greatly improved. While ensuring that the original drying time of the material remains unchanged, the overall length of the drying kiln is significantly reduced, saving space. The inlet and outlet of the heating channel are both located at one end of the drying kiln, facilitating material entry and exit management. Two conveyor lines are arranged side by side inside the heating channel to increase the transmission capacity and drying efficiency. The two conveyor lines are connected by a first transfer mechanism to ensure smooth material transmission and improve drying efficiency. At the same time, the inspection door is located at the other end of the drying kiln, which facilitates comprehensive inspection and maintenance of the interior of the drying kiln, reducing the difficulty and time of maintenance.

[0010] Furthermore, the transfer mechanism also includes a second transfer mechanism, and the two ends of the two conveyor lines are connected through the first transfer mechanism and the second transfer mechanism to form a loop.

[0011] By connecting two conveyor lines through the first and second transfer mechanisms to form a loop, materials can circulate during the transmission process without the need for frequent manual adjustments to the material transmission direction or changes in the transmission path. This improves the continuity and automation of the transmission, reduces waiting time and manual intervention in material transmission, and thus enhances the overall transmission efficiency.

[0012] Furthermore, the drying kiln body is provided with openable and closable maintenance windows evenly distributed on both sides.

[0013] By evenly setting openable and closable inspection windows on both sides of the drying kiln, it is easy to quickly locate the fault point and carry out repairs, reducing downtime for maintenance.

[0014] Furthermore, the exhaust device includes an exhaust pipe and a regulating valve. The exhaust pipe is located above the drying kiln body and is connected to the heating channel. The regulating valve is located at the connection between the exhaust pipe and the drying kiln body and is used to adjust the degree of connection between the exhaust pipe and the heating channel.

[0015] By installing an exhaust pipe above the drying kiln that connects to the heating channel and setting a regulating valve at the connection point, the degree of connection between the exhaust pipe and the heating channel can be precisely controlled, the amount of hot air emitted from the drying kiln can be flexibly controlled, excessive heat loss or uneven temperature inside the kiln can be avoided, the drying efficiency and quality can be effectively improved, and the operating parameters can be flexibly adjusted according to different drying needs.

[0016] Furthermore, the infrared temperature control device includes an infrared lamp and a temperature transmitter. The infrared lamp is installed on the inner wall of the heating channel, and the temperature transmitter is installed inside the heating channel corresponding to the infrared lamp.

[0017] By installing infrared lamps on the inner wall of the heating channel and setting temperature transmitters at corresponding positions, the temperature of the heating area can be monitored accurately in real time. Based on the feedback, the power of the infrared lamps can be quickly adjusted to achieve precise control of the heating temperature and improve the drying quality and stability.

Detailed Implementation

[0019] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings of the instruction manual include: drying kiln body 1, heating channel 1.1, inspection door 1.2, inspection window 1.3, transmission device 2, conveyor line 2.1, transfer mechanism 2.2, infrared temperature control device 3, exhaust device 4, exhaust pipe 4.1, regulating valve 4.2, and transmission tray 5.

[0020] like Figures 1 to 5 As shown, an automatic drying device for electronic ignition module propellant heads includes a drying kiln body 1, a conveying device 2, an infrared temperature control device 3, an exhaust device 4, and a conveying tray 5. The drying kiln body 1 includes a heating channel 1.1, which has an inlet and an outlet. The conveying device 2 is disposed on the heating channel 1.1, with one end connected to the inlet of the heating channel 1.1 and the other end connected to the outlet of the heating channel 1.1. The conveying tray 5 is disposed on the conveying device 2. When the conveying device 2 is running, it drives the conveying tray 5 to move along the heating channel 1.1. The exhaust device 4 is connected to the heating channel 1.1. The heating channel 1.1 has multiple heating zones that are evenly distributed, and each heating zone is provided with an infrared temperature control device 3.

[0021] In this embodiment, the electronic ignition module's propellant head is automatically and rapidly dried using infrared radiation. The propellant head is heated with precise temperature control and rapid response, eliminating the need for open flames and high-temperature airflow, thus minimizing the risk of ignition. Furthermore, the strong penetrating power of infrared radiation allows for simultaneous drying of the propellant head both inside and out, improving drying quality. The transfer tray 5 reduces wear on the mold storing the propellant head during repeated movement, extending its lifespan. The exhaust device 4 effectively removes harmful gases generated during heating, preventing their accumulation and potential safety hazards. Six heating zones are provided, allowing for different heating temperatures to be set according to different heating stages, enabling targeted heating and improving drying efficiency and quality.

[0022] The transmission device 2 includes a transfer mechanism 2.2, which includes a first transfer mechanism. The heating channel 1.1 has a U-shaped structure. The outlet and inlet of the heating channel 1.1 are both located at one end of the drying kiln body 1. The other end of the drying kiln body 1 is equipped with an openable and closable inspection door 1.2. Two conveyor lines 2.1 are installed inside the heating channel 1.1, arranged side by side. The other end of the heating channel 1.1 is connected to the two conveyor lines 2.1 through the first transfer mechanism. Specifically, the interior space of the drying kiln body 1 is divided into two parts by a baffle, and the two parts are connected at the end of the drying kiln body 1 near the inspection door 1.2, so that the heating channel 1.1 forms a U-shaped structure.

[0023] The heating channel 1.1 has a U-shaped structure, which improves space utilization and significantly reduces the overall length of the drying kiln 1 while ensuring that the original drying time remains unchanged. The outlet and inlet of the heating channel 1.1 are both located at one end of the drying kiln 1, so that the molds are picked up and placed at the same end of the drying kiln 1, which facilitates centralized processing.

[0024] The transfer mechanism 2.2 also includes a second transfer mechanism. The two ends of the two conveyor lines 2.1 are connected through the first transfer mechanism and the second transfer mechanism to form a loop.

[0025] Two conveyor lines 2.1 are arranged side by side. The two ends of the two conveyor lines 2.1 are connected by a first transfer mechanism and a second transfer mechanism to form a loop, so that the transfer tray 5 can move and be reused in a cyclical manner. No other equipment is needed to load and unload the transfer tray 5, which saves costs and reduces the working cycle.

[0026] The drying kiln body 1 has evenly arranged openable and closable maintenance windows 1.3 on both sides, which allows staff to conveniently and quickly inspect and handle faults.

[0027] The exhaust device 4 includes an exhaust pipe 4.1 and a regulating valve 4.2. The exhaust pipe 4.1 is located above the drying kiln body 1 and is connected to the heating channel 1.1. The regulating valve 4.2 is located at the connection between the exhaust pipe 4.1 and the drying kiln body 1 and is used to adjust the degree of connection between the exhaust pipe 4.1 and the heating channel 1.1.

[0028] In this embodiment, an exhaust pipe 4.1 is installed above the drying kiln body 1, ensuring that the exhaust pipe 4.1 is connected to the heating channel 1.1 inside the drying kiln body 1 to form an exhaust path. A regulating valve 4.2 is installed at the connection between the exhaust pipe 4.1 and the drying kiln body 1. This regulating valve 4.2 can be a common type such as a butterfly valve or gate valve, allowing for flexible control of the opening degree.

[0029] During production, staff manually rotate the handle of regulating valve 4.2 or operate the electric control device to change the opening and closing size of regulating valve 4.2 according to actual production conditions, such as the drying progress of materials, kiln temperature and humidity, etc. When it is necessary to enhance the exhaust effect, the opening of the regulating valve is increased to allow more gas to be discharged through the exhaust pipe 4.1; when it is necessary to reduce exhaust to maintain the temperature and humidity inside the drying kiln 1, the opening of the regulating valve is decreased, thereby achieving a dynamic balance between drying and exhaust.

[0030] The infrared temperature control device 3 includes an infrared lamp and a temperature transmitter. The infrared lamp is installed on the inner wall of the heating channel 1.1, and the temperature transmitter is installed inside the heating channel 1.1 in correspondence with the infrared lamp.

[0031] In this embodiment, the infrared temperature control device 3 requires the coordinated operation of the infrared lamp and the temperature transmitter to achieve efficient temperature control through precise installation and parameter configuration. First, an installation position is selected on the inner wall of the heating channel 1.1. A 220V, 700W, 5µm wavelength infrared lamp is fixed using a dedicated bracket, ensuring uniform spacing between the infrared lamp and the inner wall of the heating channel 1.1 to achieve full heat radiation coverage. During wiring, the live wire, neutral wire, and ground wire must be strictly distinguished. Insulating tape is used to wrap the connectors, and a withstand voltage test is performed to avoid short circuit risks. After installation, a no-load test is required to observe whether the infrared lamp heats up uniformly and without abnormal flickering.

[0032] The corresponding FB110T1Z-1000D-11000 integrated temperature transmitter needs to be installed in heating channel 1.1, corresponding to the infrared lamp position. The temperature transmitter's measurement temperature range is 0-200℃. The temperature transmitter uses a PT100 resistance temperature detector (RTD) as the sensing element and converts the temperature signal into a 4-20mA standard current output via a four-wire connection. Zero-point calibration is required during configuration: adjust the zero-adjustment potentiometer RZ at 0℃ to achieve an output current of 4mA; then set the upper limit of the range using the amplitude modulation potentiometer RG to ensure an output of 20mA at 200℃. This temperature transmitter has a built-in linearization compensation circuit that corrects the non-linear response of the PT100 RTD to a linear output, with an error controlled within ±1%.

[0033] When the infrared temperature control device 3 is running, the temperature transmitter collects temperature data in the heating channel 1.1 in real time and transmits it to the PLC control system via a signal line. The PLC control system dynamically controls the output power of the infrared lamps by adjusting the conduction angle of the solid-state relays based on the deviation between the set temperature and the measured temperature using a PID algorithm. For example, when the measured temperature is lower than the set value, the system automatically increases the output current to boost the lamp power; conversely, it reduces the power to cool the lamps. The entire control process has a response time of less than 2 seconds, and the temperature fluctuation range is controlled within ±2℃, ensuring heating efficiency while avoiding overshoot. All electrical connections must comply with GB 50254-2014 standards, and the grounding resistance of the infrared temperature control device casing must be less than 4Ω to ensure operational safety.
