[0070] The application will be further described below in conjunction with the specific embodiments. The accompanying drawings are only used for illustrative explanation and should not be understood as a limitation to the patent. In order to better illustrate the embodiments of the application, some components in the drawings may be omitted, enlarged or reduced, and do not represent the actual product size.

[0071] EMBODIMENT

[0072] As Figures 1-10As shown, a lead processing system includes a lead feeding device 2, a drug delivery device, an encapsulation device 8, and a winding device 22.

[0073] The number of wire feeding devices 2 is at least one, that is, one or more, preferably multiple. The wire feeding device 2 is provided with the lead wire 24 to be processed. The wire feeding device 2 includes a wire feeding frame and at least one spool, the spool being rotatably mounted on the wire feeding frame, and the lead wire 24 to be processed is wound onto each spool. Preferably, multiple spools are provided on the same wire feeding frame.

[0074] The lead 24 to be processed can be cotton thread. When multiple spools are set on the same pay-off frame, the pay-off device 2 can simultaneously hold several cotton thread spools, each of which can be processed simultaneously without affecting each other, resulting in high processing efficiency. Furthermore, multiple strands of cotton thread can be combined and unfolded for subsequent drug administration, drying, and / or encapsulation, etc., as needed. The lead 24 formed by winding multiple strands of cotton thread has greater mechanical strength and is less prone to breakage.

[0075] In this embodiment, the drug delivery device is used to receive the lead wire 24 released from the wire release device 2 and add drug to the lead wire 24. The drug delivery device includes a mixing tank 4, a delivery pipeline, and a drug-adhesive device 5. The mixing tank 4 is equipped with a stirring device for mixing the drug, and the drug-adhesive device 5 is connected to the outlet of the mixing tank 4 via the delivery pipeline. The drug-adhesive device 5 is configured to adhere the drug to the lead wire 24.

[0076] The drug mixture includes combustible raw materials and / or a solidifying agent. Specifically, the mixing tank 4 is used to uniformly stir the drug mixture, solidifying agent, and other drug components to achieve a good viscosity. Combustible raw materials refer to materials containing combustibles such as sulfur, nitrates, phosphorus, potassium chlorate, and charcoal powder. The solidifying agent is an adhesive that holds the combustible raw materials to the lead wire 24. In other words, the drug delivery device can efficiently, uniformly, and sequentially mix and add combustible raw materials, solidifying agents, and other drug components onto the lead wire 24.

[0077] During processing, the drug is added from the inlet of the mixing tank 4 according to the required ratio, and is mixed evenly in the mixing tank. The evenly mixed drug is output from the outlet of the mixing tank 4 and transported to the adhesive device 5 through the conveying pipeline. For example, the stirring device in the mixing tank includes a rotating blade 401 and a motor that drives the rotating blade 401 to rotate.

[0078] Among them, such as Figure 3 As shown, in the first type of drug-adhesive device 5, the drug-adhesive device 5 includes a drug-adhesive box with an opening for the lead wire 24 to pass through, and the drug-adhesive box stores the drug. When the lead wire 24 passes through the drug-adhesive box, the drug in the drug-adhesive box adheres to the lead wire 24.

[0079] Among them, such as Figure 4As shown in the second adhesive device 5, the adhesive device 5 comprises a storage bin 504, a drug body advancing device 502 and a drug outlet 501, the storage bin 504 is connected to the drug outlet of the mixing device 4 through a conveying pipeline, the drug outlet 501 is used to output the drug body to adhere to the lead 24, and the drug body advancing device 502 is used to advance the drug body in the storage bin 504 to the drug outlet 501.

[0080] The embodiment provides a preferred drug body advancing device 502, and the drug body advancing device 502 comprises a quantitative drug body advancing device 502. Further preferably, the quantitative drug body advancing device 502 comprises a metering valve 503 and / or a quantitative advancing screw. Therefore, the drug body can be quantitatively output through the quantitative drug body advancing device 502 such as the quantitative advancing screw, the lead 24 can pass through the drug outlet 501, the combustible raw material can be in sufficient contact with the lead 24 and adhere to the lead 24, and the process is called “drug adding”. The size of the adhered drug can be controlled by adjusting the flow size of the metering valve 503. On one hand, the drug body can be saved, and on the other hand, the safety is higher because too much combustible raw material is not exposed in the production environment.

[0081] Preferably, the number of the adhesive device 5 is multiple, and one mixing device 4 is connected to multiple adhesive devices 5 through a conveying pipeline. Therefore, the drug feeding device can simultaneously feed multiple leads 24 released from the lead releasing device 2, and the drug feeding efficiency is significantly improved.

[0082] In the embodiment, the sealing device 8 is used to seal the outer surface of the lead 24 to which the drug body is added to form the lead 24. As shown in the figure, Figures 5-7 The sealing device 8 comprises a rack and a paper sealing device, the paper sealing device comprises a lead winding device 811 and a paper releasing device 802, the paper releasing device 802 is used to release the paper material 25 to the lead winding device 811, and the lead winding device 811 is arranged on the rack and located at the rear of the paper releasing device 802. The paper releasing device 802 comprises a paper disc, the paper disc is rotatably arranged on the rack, and the paper material 25 is wound on the paper disc. In the processing, the paper material 25 is a paper tape with a certain length, the paper tape is wound on the paper disc, when the lead winding device 22 winds the lead, the lead 24 and the paper tape are moved, at this time, the paper disc rotates, and the paper tape is released from the paper disc. The paper material 25 is usually selected from a cotton paper, a leather paper and a paper tape commonly used in firecrackers and fireworks. A plurality of paper discs can be arranged on the rack, the paper discs are simultaneously sealed, do not affect each other and have high processing efficiency.

[0083] In this embodiment, the take-up device 811 has a through hole 818 for the lead wire 24 and the wrapping paper material 25 to pass through the through hole 818 and be combined together, and the through hole 818 has a preset hole diameter, for example, the hole diameter of the through hole 818 is close to the size of the lead wire 24, that is, the same, slightly larger or slightly smaller, so that the combined lead wire 24 and the wrapping paper material 25 are tightened and encapsulated on the outer layer of the lead wire 24 when passing through the hole wall of the through hole 818 under the pressure of the wrapping paper material 25.

[0084] Preferably, the through hole 818 is trumpet-shaped with a gradually decreasing hole diameter. The through hole 818 has a certain length, and one or more lead wires 24 and the wrapping paper material 25 after being medicated are pulled into the through hole 818 at the same time, the wrapping paper material 25 is tightened and encapsulated on the outer layer of the lead wire 24, which is called "paper wrapping" in this process, and a paper-wrapped lead wire 24 is obtained. The encapsulating material is usually a paper tape with a certain width. In the paper wrapping process, the hole diameter of the through hole 818 can be adjusted according to the thickness of the required lead wire 24.

[0085] Preferably, the encapsulating device 8 further comprises a guide device 801 arranged in front of the take-up device 811, and the guide device 801 is used to define the running direction of the lead wire 24, so that the lead wire 24 and the wrapping paper material 25 are aligned at the take-up device 811. Because the guide device 801 is also included, the running direction of the lead wire 24 can be fixed to be more accurately introduced into the take-up device 811, avoiding deviation of the lead wire 24 and the wrapping paper material 25 at the take-up device 811. Specifically, the guide device 801 comprises a lead wire plate fixed on the rack, and the lead wire plate is provided with a through hole for the lead wire 24 to pass through.

[0086] In this embodiment, the encapsulating device 8 further comprises a driving device and at least one level of lead wrapping device. Preferably, the lead wrapping device comprises two or more levels, and the two or more levels of lead wrapping device are arranged in sequence behind the take-up device 811, so that the outer surface of the lead wire 24 is wrapped with lead wrapping material multiple times. Exemplarily, Figure 5 and Figure 6 The lead wrapping device is shown to comprise two levels of lead wrapping device.

[0087] Among them, the lead wrapping device comprises a rotating disc 803 which is rotatably arranged on the rack and located behind the take-up device 811, and the rotating disc 803 is provided with a plurality of wire rollers 804 on which the lead wrapping material is wound, and the lead wire 24 after being wrapped with paper and the lead wrapping material on the wire roller 804 pass through the center hole of the rotating disc 803. The driving device is drivingly connected with the rotating disc 803 to drive the rotating disc 803 to rotate, so that the lead wrapping material on the wire roller 804 is wound on the outer surface of the lead wire 24.

[0088] The driving device comprises a motor 805 and a belt transmission assembly. The motor drives the belt transmission assembly. The belt transmission assembly is drivingly connected to the rotating disc 803 in each stage of the wire wrapping device, so that the rotating disc 803 rotates under the driving of the motor 805.

[0089] In this embodiment, the rotating disc 803 drives the wire on the wire roller 804 to wrap around the outer surface of the paper wrapping lead 24. This process is called "wire wrapping". The rotating disc 803 is used to wrap the wire around the outer surface of the paper wrapping lead 24 to ensure that the wrapped lead 24 does not come apart, maintains a tight state, and is isolated from air to avoid problems such as lead 24 dropping slag, getting wet, etc., ensuring the quality of the lead 24 while avoiding safety accidents. According to production needs, two or more stages of wire wrapping devices can be sequentially arranged, such as 3-wire leads, 4-wire leads, 5-wire leads, etc. This means that 3-5 leads 24 are wrapped together by the paper wrapping tape to form a 3-5-wire lead with greater strength. The outer surface of the paper wrapping lead 24 is wrapped with multiple wires to form a tight "paper wrapping wire lead 24". Because the lead 24 contains flammable materials, it is a flammable and explosive hazardous material. After passing through the wrapping device 8, the lead 24 containing flammable materials is isolated from the outside world, which can ensure that the flammable materials and other materials are not easily detached and oxidized. At the same time, the mechanical strength of the lead 24 wrapped with the wrapping material increases, which is not easily broken.

[0090] The belt transmission assembly comprises a driving wheel 806, a driven wheel 807, and a transmission belt 808. The driving wheel 806 is connected to the output shaft of the motor. The driving wheel 806 is connected to the driven wheel 807 through a rotating belt. The driven wheel 807 is drivingly connected to the rotating disc 803.

[0091] Preferably, a plurality of rotating discs 803 are arranged on each stage of the wire wrapping device. The number of driven wheels 807 and transmission belts 808 is also a plurality. The driving wheel 806 is connected to the first driven wheel 807 through a rotating belt. The first driven wheel 807 is drivingly connected to the other driven wheels 807 through a transmission belt 808 or a rotating shaft. In this way, the wire wrapping process for multiple leads 24 can be realized, the processing efficiency is higher, and more motors are not needed, which reduces the number of motors, energy consumption, and the cost of the electric control system.

[0092] When the wire wrapping device comprises two or more stages, at least one stage of the wire wrapping device is provided with a clutch device 810 for loosening or braking the driving connection between the rotating disc 803 and the belt transmission assembly in the wire wrapping device. In this way, the braking, steering, and rotating speed of the rotating disc 803 can be effectively adjusted.

[0093] Preferably, the clutch device 810 comprises a driving sprocket 812, a driven sprocket 815, a transmission chain 817 and a clutch sprocket 816, the driving sprocket 812 is drivingly connected with the belt transmission assembly, the driven sprocket 815 is connected with the driving sprocket 812 through the transmission chain 817, and the clutch sprocket 816 is movably arranged on the frame and used for drivingly or releasingly abutting against the transmission belt 808 in the corresponding wrapping device by moving.

[0094] Further preferably, one of the driven sprockets 807 is sleeved on the rotating shaft 809, the rotating shaft 809 is provided with a worm 814, the driving sprocket 812 has a coaxial turbine 813, and the turbine 813 is engaged with the worm 814.

[0095] In the embodiment, the winding device 22 is used for pulling and winding the finished lead 24. Specifically, the winding device 22 is composed of a frame, a rotating shaft, a motor and the like, and the motor of the winding device 22 provides initial power for the lead 24 to travel when the motor is started. The specific structural relationship of the components in the winding device 22 can be referred to the prior art, and will not be described in detail in the present embodiment.

[0096] In the embodiment, the first-stage drying device 6 for drying the lead 24 is arranged between the dosing device and the wrapping device 8. Thus, the relatively wet lead 24 after dosing is first dried, and then subjected to the wrapping process, which can significantly increase the adhesion effect of the drug on the lead 24, and the quality of the lead 24 is better.

[0097] Preferably, the second-stage drying device 12 for drying the lead 24 is arranged between the wrapping device 8 and the winding device 22. Thus, the wrapped lead 24 can be dried, and the quality stability of the lead 24 product is further improved.

[0098] The first-stage drying device 6 and the second-stage drying device 12 can adopt a drying cylinder, and the specific structure of the drying cylinder can be referred to the prior art, and the specific structure of the drying cylinder will not be described in detail in the present embodiment.

[0099] Further preferably, the first-stage drying device 6 further comprises a temperature detection unit 14 and a temperature control unit, the temperature detection unit 14 performs real-time monitoring on the temperature of the first-stage drying device 6, the temperature control unit receives the temperature signal sent by the temperature detection unit 14, and when the temperature exceeds a preset upper limit value, the temperature control unit stops the heating of the first-stage drying device 6, and when the temperature is lower than a preset lower limit value, the temperature control unit controls the first-stage drying device 6 to resume heating.

[0100] Further preferably, the second-stage drying device 12 further comprises a temperature detecting unit 14 for monitoring the temperature of the second-stage drying device 12 in real time, and a temperature control unit for receiving the temperature signal sent by the temperature detecting unit 14, and stopping the heating of the second-stage drying device 12 when the temperature exceeds a preset upper limit, and controlling the second-stage drying device 12 to resume heating when the temperature is lower than a preset lower limit.

[0101] Thus, the temperature of the first-stage drying device 6 and the second-stage drying device 12 is monitored in real time, for example, when the temperature of the first-stage drying device 6 exceeds an upper limit such as 60℃, the heating of the first-stage drying device 6 is stopped, and when the temperature of the first-stage drying device 6 is lower than a lower limit such as 30℃, the heating is resumed. Through the detection and control of the temperature, the temperature in the drying device is kept in an appropriate range, avoiding overheating or overcooling, ensuring the safety of production, and improving the utilization efficiency of heat energy.

[0102] Further preferably, the first-stage drying device 6 and the second-stage drying device 12 are connected by a pipeline 7 and share a heat source. Thus, the first-stage drying device 6 and the second-stage drying device 12 are connected by the pipeline 7 to form a hot air circulation system, which can reduce heat loss and improve the utilization efficiency of heat energy.

[0103] In the present embodiment, the first-stage drying device 6 and the second-stage drying device 12 can be electric hot air drying, air energy drying, large solar energy drying, and / or heat conduction oil drying, which can reduce the humidity of the lead wire 24 and make the combustible material more firmly adhere to the lead wire 24.

[0104] In the present embodiment, the lead wire processing system is provided with a safety isolation device 10, 17 at one or more positions, which is used to cut off the lead wire 24 at the safety isolation device 10 when it is detected that the lead wire 24 is broken at a certain position.

[0105] As shown in Figure 8 As a preferred safety isolation device 10, the safety isolation device 10 comprises a tension threading plate 101, an electromagnetic switch 103, a magnetic element 103, and a lead cutting element 105. The lead wire 24 is threaded on the tension threading plate 101 in a pre-tensioned state. The electromagnetic switch 103 is connected to the tension threading plate 101 and is used to trigger the electromagnetic switch 103 when the tension threading plate 101 moves due to the breakage of the lead wire 24. The magnetic element is arranged between the electromagnetic switch 103 and the lead cutting element 105, so that when the electromagnetic switch 103 is triggered, the lead cutting element 105 is driven by the magnetic element to cut off the lead wire 24 at the safety isolation device 10.

[0106] Further preferably, the safety isolation device 10 further comprises an elastic element 104 for resetting the lead cutting element 105.

[0107] Thus, the safety isolation device 10 can be used to isolate the safety hazard and avoid the risk of transmission to other processes. For example, the running lead wire 24 passes through the tension threading plate 101, and since the moving lead wire 24 itself has a certain tension, it will pull the tension threading plate 101 in a predetermined direction. The displacement of the tension threading plate 101 causes the electromagnetic switch 103 connected thereto to close. When a burning or other dangerous situation occurs and the lead wire 24 is burned off, the tension of the lead wire 24 disappears, causing the displacement of the tension threading plate 101 to disappear, and it returns to its original position and causes the electromagnetic switch 103 connected thereto to open. After the electromagnetic switch 103 is opened, it will cause the magnetic force element to move, and the movement of the magnetic force element will cause the elastic element connected thereto to be tightened or relaxed. The tightening or relaxation of the elastic element will push the cutting element 105 to cut off the lead wire 24, and after the lead wire 24 is cut off, the burning or other danger will be blocked. Among them, the safety isolation device 10 can be selectively arranged at one or more positions in the system of the embodiment, such as between the dosing device and the first-stage drying device 6, or between the first-stage drying device 6 and the encapsulation device 8, or between the second-stage drying device 12 and the lead wire winding device 22, etc.

[0108] In the embodiment, a main control unit 1 for controlling each device in the lead wire processing system is also included, such as a PLC, a single-chip microcomputer, a touch device, an industrial computer, etc. The main control unit 1 can adjust the switching of the motors in each device, display the motor operating parameters including the power consumption and operating power, and achieve control over each device.

[0109] In the embodiment, one or more positions in the lead wire processing system are provided with a broken wire monitoring device 3 for monitoring the trigger signal when the lead wire 24 is broken and sending it to the main control unit 1.

[0110] As Figure 9As shown, as a preferred broken wire monitoring device 3, the broken wire monitoring device 3 comprises a photoelectric monitor 303 and a sleeve 302, the sleeve 302 is hung on the lead wire 24, and the photoelectric monitor 303 is arranged beside, for example, below the sleeve 302 and the lead wire 24, for detecting whether the sleeve 302 falls off the lead wire 24. During system operation, the lead wire 24 passes through the sleeve 302, and the photoelectric monitor 303 is arranged below the sleeve 302 and the lead wire 24; when the lead wire 24 is broken, the sleeve 302 falls down and is monitored by the photoelectric monitor 303 below, triggering the equipment to stop and sending a warning. The broken wire monitoring device 3 is used to monitor whether there is a broken wire of the lead wire 24 or multiple lead wires 24 in real time. Generally, infrared and other photoelectric detection means can be used to monitor the broken wire condition, and the operation of the lead wire processing equipment is suspended until the broken wire is repaired and the operation is restarted, so as to avoid the broken wire causing defective products. The broken wire monitoring device 3 can be selectively arranged at one or more positions in the system of the present application, such as between the dosing device and the first-stage drying device 6, or between the first-stage drying device 6 and the encapsulating device 8, or between the second-stage drying device 12 and the winding device 22, etc.

[0111] In this embodiment, the fault monitoring device 9, 16 is arranged at one or more positions in the lead wire processing system, for detecting the tension of the lead wire 24, and generating a trigger signal and sending it to the main control unit 1 when the tension of the lead wire 24 exceeds a preset threshold value.

[0112] As shown in FIG. 1, the lead wire processing system of the present application comprises a main control unit 1, a lead wire processing device 2, a lead wire 24, a fault monitoring device 9, 16, and a broken wire monitoring device 3. Figure 10As shown, as a preferred fault monitoring device 9, the fault monitoring device 9 comprises an elastic element 902, a weight bar 901 and a photoelectric monitor 903, the lead wire 24 passes through the weight bar 901, the elastic element 902 applies elasticity to the weight bar 901, and the weight bar 901 is configured to restore the original position when the tension of the lead wire 24 increases and exceeds the elasticity of the elastic element acting on the weight bar 901, so that the photoelectric monitor 903 triggers a signal and sends it to the main control unit 1. The fault monitoring device 9 is used to monitor whether there is an overload of the lead wire 24 caused by the increase of the tension of the lead wire 24 due to adhesion, winding, knotting or accumulation of the lead wire 24 caused by the shedding of the packaging material of the lead wire 24 in the system. When the system is running normally, the lead wire 24 passes through the weight bar 901, and the elastic element applies a certain elasticity to the weight bar 901, and the elasticity is the tension that the lead wire 24 can withstand when running normally. The weight bar 901 is displaced due to the elasticity, and the displacement causes the photoelectric monitor 903 to be in an on state. When the tension of the lead wire 24 increases due to a fault and exceeds the elasticity of the weight bar 901, the weight bar 901 will restore to the original position, the displacement disappears, and the photoelectric monitor 903 is cut off, thereby triggering the shutdown of the device of the application and sending a warning. After the fault is eliminated, the operation is restarted to avoid frequent disconnection affecting production efficiency and causing safety accidents. The fault monitoring device 9 can be selected to be arranged at one or more positions in the system of the application, such as between the dosing device and the first-stage drying device 6, between the first-stage drying device 6 and the packaging device 8, between the second-stage drying device 12 and the winding device 22, etc.

Specifically, the traction device 11 can include a motor, a rolling roller and / or a steering wheel. The rolling roller can be a single roller or multiple rollers. When it is a single roller, the motor drives the rolling roller to rotate, and the lead wire 24 is wound around the rolling roller one or more times, and the rolling roller pulls the lead wire 24 forward through friction. When it is a multiple roller, the motor drives the driving roller to rotate, and the driving roller drives the driven roller to rotate through friction, and the lead wire 24 passes between the two rollers, and the rollers pull the lead wire 24 forward. The steering wheel is used to guide the lead wire 24 to the device of the next process. The device acts to pull the lead wire 24 out of the device of the previous process and uniformly feed it to the device of the next process. When the pulling force of the lead wire 24 is insufficient, the lead wire 24 in the system may
