Description

Technical Field

[0001] The present invention relates to the technical field of emulsion explosive packaging, and particularly to an automatic packaging device for emulsion explosives with a safety protection mechanism. Background Art

[0002] In the field of industrial explosive production, emulsion explosives have become the mainstream blasting materials in fields such as mine exploitation and tunnel engineering due to their characteristics such as high energy density, low mechanical sensitivity, and good water resistance. However, the packaging link in its production process has long faced technical bottlenecks, mainly reflected in the following aspects:

[0003] Traditional stirring and defoaming equipment mostly adopts a single-axis stirring structure, with limited processing capacity for high-viscosity emulsion explosives. During the stirring process, the fluidity of the material is poor, and the bubble breakage rate is low, resulting in uneven density of the packaged explosive and directly affecting the stability of the blasting performance.

[0004] Existing stirring tanks mostly rely on external air cooling for heat dissipation. During the stirring and defoaming process, the temperature of the material is likely to exceed the critical value (usually 80°C), resulting in the destruction of the emulsion system or even thermal decomposition. At the same time, there is a lack of effective electrostatic elimination measures. When transporting and processing flammable and explosive substances, electrostatic accumulation may trigger serious safety accidents. Summary of the Invention

[0051] Please refer to Figure 1 , the present application provides a new technical solution: an automatic encapsulation device for emulsion explosive with a safety protection mechanism, including:

[0052] A material processing unit, the material processing unit includes a conveyor 100 and a stirring and defoaming machine 200. The discharge end of the conveyor 100 is located above the feed inlet of the stirring and defoaming machine 200. The conveyor 100 is used to convey the material to be encapsulated into the stirring and defoaming machine 200. The stirring and defoaming machine 200 is used to stir and defoam the material to be encapsulated, improve the density between materials, and ensure the overall encapsulation quality of the emulsion explosive;

[0053] A material encapsulation unit, the material encapsulation unit includes a screw filling machine 300 and a plastic film forming mechanism 500. The screw filling machine 300 is located below the discharge port of the stirring and defoaming machine 200. The screw filling machine 300 is used to fill the defoamed material. The plastic film forming mechanism 500 is located below the discharge port of the screw filling machine 300. The plastic film forming mechanism 500 is used to form a plastic film bag for the material to fill the defoamed material;

[0054] An encapsulation execution unit, the encapsulation execution unit includes a capper 600 and a traction mechanism 700. The capper 600 is located below the plastic film forming mechanism 500. The capper 600 is used to punch and encapsulate the filled plastic film bag. The traction mechanism 700 is located below the capper 600. The traction mechanism 700 is used to traction the encapsulated plastic film bag to move;

[0055] Safety protection unit, the safety protection unit includes an ion blower 910, a cooling water circulation machine 920 and a control valve 930. The ion blower 910 is arranged above the conveyor 100 and is inclined at 15° to the conveyor belt of the conveyor 100, and is used to blow off the static electricity on the conveyed material on the conveyor 100. The cooling water circulation machine 920 is arranged on one side of the stirring and defoaming machine 200 and is used to cool the stirring and defoaming machine 200 during operation. The control valve 930 is located at the discharge port of the stirring and defoaming machine 200. When the temperature of the stirring and defoaming machine 200 exceeds the set threshold, the material inside the stirring and defoaming machine 200 is sealed to prevent the material from being conveyed downward.

[0056] During use, the emulsified explosive material to be encapsulated is first conveyed by the conveyor 100 into the stirring and defoaming machine 200. The conveyor 100 continuously transports the material from the feeding place to above the feeding port of the stirring and defoaming machine 200. The material falls into the stirring and defoaming machine 200 by gravity. The stirring and defoaming machine 200 starts the stirring function, and stirs the material through components such as stirring rods to eliminate the air bubbles in the material and make the material reach a state suitable for encapsulation. The material after stirring and defoaming flows out from the discharge port of the stirring and defoaming machine 200 and enters the screw filling machine 300. The screw filling machine 300 uses structures such as a screw distributor and a horizontal medicine feeding screw to distribute and convey the material, and accurately fills the material into the material plastic film bag formed by the plastic film forming mechanism 500. The plastic film forming mechanism 500 forms the plastic film on the plastic film roll into a plastic film bag capable of accommodating the material. The filled plastic film bag drops to the capping machine 600 under the action of gravity, and the capping machine 600 caps and seals it to seal the plastic film bag. After that, the traction mechanism 700 starts to work, and traction the encapsulated plastic film bag to move downward to prepare for subsequent conveying and other operations.

[0057] The ion blower 910 continuously blows ion wind to the material conveyed on the conveyor 100 to neutralize the static electricity on the surface of the material and prevent the accumulation of static electricity from causing danger. The cooling water circulation machine 920 is connected to the cooling jacket of the stirring and defoaming machine 200 through a cooling pipe, circulates and conveys the cooling water, and takes away the heat generated during the operation of the stirring and defoaming machine 200 to avoid safety problems caused by too high temperature. The control valve 930 controls the material flow rate and the opening and closing of the discharge port of the stirring and defoaming machine 200 as needed.

[0058] Each unit works together to realize the automatic process of emulsified explosive from material processing to encapsulation, reduces manual intervention, and greatly improves production efficiency. The safety protection unit conducts protection from aspects such as static electricity elimination, temperature control and material flow control, effectively reduces the safety risks during the production process, and ensures the safety of operators and equipment.

[0059] In some embodiments, the automatic encapsulation device further includes an electrical control box 400, which is used to control the coordinated operation of each mechanism of the device. The electrical control box 400 is electrically connected to each mechanism in the device, such as the conveyor 100, the stirring and degassing machine 200, the screw filling machine 300, the card punching machine 600, and the traction mechanism 700, through the built-in control system and circuit; according to the preset program and logic, it sends control signals to each mechanism to adjust their operating parameters, such as the rotation speed of the motor, the opening and closing of the valve, etc., so that each mechanism can work together in a set order and rhythm; at the same time, each mechanism also feeds back its own operating state to the electrical control box 400 for the electrical control box 400 to monitor and adjust in real time.

[0060] The presence of the electrical control box 400 enables the device to achieve automatic operation, reduces the complexity and errors of manual operation, and improves the accuracy and consistency of production.

[0061] In some embodiments, the automatic encapsulation devices are tightly installed together through the installation frame, and the effect of automatic filling and encapsulation can be achieved. The entire device is tightly installed together through the installation frame to ensure the relative positions of each mechanism are fixed, reduce vibration and displacement, and ensure the stability of the device operation. The installation frame tightly installs each mechanism together, improves the overall stability of the device, reduces failures and damages caused by vibration and displacement, and extends the service life of the device.

[0062] Please refer to Figure 2 , in some embodiments, the conveyor 100 includes a first conveyor belt 101, the surface of the first conveyor belt 101 is coated with a carbon nanotube conductive coating, and a feed bin 102 is arranged above the feeding end of the first conveyor belt 101. Materials are conveyed to the first conveyor belt 101 through the feed bin 102, and the materials to be encapsulated are conveyed to the inside of the feed bin 102 through the first conveyor belt 101.

[0063] The materials first enter the feed bin 102, and the feed bin 102 plays a role in storing and buffering the materials. Then the materials fall on the first conveyor belt 101, and the first conveyor belt 101 starts to rotate driven by a driving device such as a motor, conveys the materials from the feeding end to the discharging end, and finally the materials fall into the stirring and degassing machine 200 by gravity. The surface of the first conveyor belt 101 is coated with a carbon nanotube conductive coating, which can quickly conduct the static electricity generated by the materials during the conveying process, avoid static electricity accumulation, reduce the risk of safety accidents such as explosion caused by static electricity, and improve the safety of production.

[0064] Please refer to Figures 3 - 4, in some embodiments, the stirring and defoaming machine 200 includes a stirring tank 201. Inside the stirring tank 201, two stirring rods 203 are rotatably connected. The two stirring rods 203 are used to stir the materials inside the stirring tank 201. The two stirring rods 203 are arranged in a spiral shape for degassing the materials to be encapsulated. On the sides of the two stirring rods 203, serrated teeth 204 are provided. By setting the serrated teeth 204, the bubbles between the materials can be eliminated more quickly. The two stirring rods 203 are driven by a driving mechanism to be rotatably connected inside the stirring tank 201.

[0065] In some embodiments, the tooth tip of the serrated tooth 204 is an acute triangle, and the tooth root has a circular arc transition, forming a streamline structure similar to "shark teeth"; the serrated teeth 204 are evenly distributed along the spiral track of the stirring rod 203, and the serrated teeth of adjacent spiral coils are arranged in a staggered manner to form an interleaved shearing area. The serrated teeth 204 are fixed to the side wall of the stirring rod 203 by laser welding or integral molding process.

[0066] In this embodiment, the driving mechanism includes a first motor 205. Below the first motor 205, there is a gear transmission box 210. Inside the gear transmission box 210, a main gear 211 is rotatably connected. The main gear 211 is fixedly installed with the output shaft of 206. The main gear 211 is driven by 206 to be rotatably connected inside the gear transmission box 210. On both sides of the main gear 211, there are meshing secondary gears 212. The two secondary gears 212 are rotatably connected inside the gear transmission box 210 through connecting rods 213. The lower ends of the two connecting rods 213 are respectively fixedly connected to the two stirring rods 203 for driving the stirring rods 203 to be rotatably connected inside the stirring tank 201.

[0067] During use, after the first motor 205 is started, it drives the main gear 211 inside the gear transmission box 210 to rotate; the main gear 211 meshes with the secondary gears 212 on both sides, thereby driving the secondary gears 212 to rotate; the secondary gears 212 are fixedly connected to the stirring rods 203 through the connecting rods 213, and further drive the stirring rods 203 to rotate inside the stirring tank 201; during the rotation of the serrated teeth 204 on the stirring rods 203, the bubbles in the materials can be cut, accelerating the rupture and elimination of the bubbles, and realizing the degassing of the materials to be encapsulated. The design of the double stirring rods 203 cooperating with the serrated teeth 204 can quickly and effectively eliminate the bubbles in the materials, improve the uniformity and stability of the materials, and thus ensure the quality of the subsequent encapsulated products.

[0068] In this embodiment, at the lower end of the stirring tank 201, there is a discharge port 202. The discharge port of the discharge port 202 is communicated with the feed port of the spiral filling machine 300. The discharge port 202 controls the conveyance of the materials into the spiral filling machine 300 through a control valve 930.

[0069] During use, the material after stirring and degassing flows out through the discharge port 202 at the lower end of the stirring tank 201; the control valve 930 controls the opening and closing of the discharge port 202 and the material flow rate as needed, so that the material can be transported to the screw filling machine 300 at an appropriate speed and quantity. The control of the discharge port 202 by the control valve 930 makes the material transportation more accurate, avoids waste and over-transportation of the material, and improves the production efficiency and economy.

[0070] In some embodiments, the cooling water circulator 920 is located on one side of the stirring tank 201. The cooling water circulator 920 uses an Easycool small cooling water circulator EPC08. A cooling jacket 924 is provided on the outer side of the stirring tank 201. A cooling pipe 923 is spirally wound inside the cooling jacket 924. The water inlet of the cooling pipe 923 is connected to the water outlet of the cooling water circulator 920 through a water inlet pipe 921, and the water outlet of the cooling pipe 923 is connected to the water inlet of the cooling water circulator 920 through a water outlet pipe 922. A temperature sensor 925 is provided inside the stirring tank 201 for monitoring the temperature of the material during the stirring process inside the stirring tank 201.

[0071] During use, the temperature sensor 925 monitors the temperature of the material during the stirring process inside the stirring tank 201 in real time and transmits the temperature signal to the cooling water circulator 920; when the temperature inside the stirring tank 201 exceeds the set value, the cooling water circulator 920 is started, and the cooling water is transported to the cooling pipe 923 through the water inlet pipe 921; the cooling pipe 923 is spirally wound inside the cooling jacket 924 of the stirring tank 201, and can fully exchange heat with the stirring tank 201 to take away the heat inside the stirring tank 201; the cooling water after absorbing heat flows back to the cooling water circulator 920 through the water outlet pipe 922 and is recycled after cooling treatment. The cooperation of the temperature sensor 925 and the cooling water circulator 920 can control the temperature inside the stirring tank 201 in real time and accurately, avoid the instability of the performance of the emulsion explosive or the occurrence of danger due to too high temperature, and ensure the safety of the production process and the product quality.

The materials after being distributed by the two spiral distributors 302 fall onto the horizontal medicine feeding screw 303, and the horizontal medicine feeding screw 303 conveys the materials to the discharging port of the hopper 301. The discharging port of the hopper 301 is connected to a medicine injection pipe 307. The medicine injection pipe 307 is connected to the inside of the hopper 301. Inside the medicine injection pipe 307, there is a medicine injection screw 305 for filling materials into the material plastic film bag.

[0073] In this embodiment, the horizontal medicine feeding screw 303 is driven by a second motor 304 to rotate horizontally inside the hopper 301, and the medicine injection screw 305 rotates inside the medicine injection pipe 307 through a third motor 306.

[0074] The materials flowing out from the discharging port of the stirring and defoaming machine 200 enter the hopper 301 of the spiral filling machine 300. The materials first pass through the two spiral distributors 302. The spiral distributors 302 conduct preliminary distribution of the materials to make the materials evenly distributed. The distributed materials fall onto the horizontal medicine feeding screw 303. The second motor 304 drives the horizontal medicine feeding screw 303 to rotate horizontally inside the hopper 301 and convey the materials to the discharging port of the hopper 301. At the discharging port, the materials enter the medicine injection pipe 307. The third motor 306 drives the medicine injection screw 305 inside the medicine injection pipe 307 to rotate, and accurately fills the materials into the material plastic film bag located outside the medicine injection pipe 307. The combination of the spiral distributors 302 and the horizontal medicine feeding screw 303 realizes the even distribution and stable conveyance of the materials. The medicine injection screw 305 ensures that the materials can be accurately filled into the plastic film bag, improving the filling accuracy and efficiency.

[0075] By arranging the spiral distributors 302, the horizontal medicine feeding screw 303 and the medicine injection screw 305 to conduct spiral conveyance of the materials, it is possible to avoid material accumulation and pipeline blockage, with high filling efficiency. At the same time, it can also avoid the problem of overheating of the medicine injection pipe 307 caused by single - spiral conveyance, improving the safety of the device.

[0076] Please refer to Figure 6, in some embodiments, the plastic film forming mechanism 500 includes a plastic film roll 510. The plastic film roll 510 is conveyed to the inside of the plastic film former 540 through a film guiding mechanism 530 for forming a plastic film bag. The medicine injection tube 307 is arranged inside the plastic film former 540. The plastic film is formed between the medicine injection tube 307 and the plastic film former 540, and the formed plastic film bag is sleeved on the surface of the medicine injection tube 307. A tape roll 550 is arranged on the plastic film bag sealing side of the plastic film former 540. The tape roll 550 is in contact with the plastic film bag sealing part on the plastic film former 540 through a tape roll roller 551, and is used for bonding the side of the plastic film bag. The normal temperature tape bonding technology is adopted to replace the high-temperature bonding method, avoiding the problem of safety hazards caused by high-temperature bonding and improving the safety of the device.

[0077] The plastic film on the plastic film roll 510 is guided and conveyed to the inside of the plastic film former 540 through the film guiding mechanism 530. The medicine injection tube 307 is arranged inside the plastic film former 540. When the plastic film passes between the medicine injection tube 307 and the plastic film former 540, it is formed by the plastic film former 540 to form a plastic film bag sleeved on the surface of the medicine injection tube 307. The tape roll 550 on the plastic film bag sealing side of the plastic film former 540 is in contact with the plastic film bag sealing part through a tape roll roller 551, and pastes the tape on the side of the plastic film bag to achieve preliminary sealing. Then, the tape compaction mechanism 560 compacts the bonded tape to make the tape closely fit the plastic film bag and ensure the sealing of the plastic sealed bag. The plastic film forming mechanism 500 can accurately form the plastic film into a plastic film bag suitable for filling, and through tape sealing and compaction treatment, ensures the sealing and quality of the plastic film bag.

[0078] In this embodiment, a tape compaction mechanism 560 is arranged below the tape roll roller 551. The tape compaction mechanism 560 is used for compacting the bonded tape to ensure the sealing of the plastic sealed bag. A plastic film damping mechanism 570 is arranged below the tape compaction mechanism 560, and is used for slowing down the descending speed of the plastic film bag to avoid the phenomenon of plastic film deviation caused by the too fast descending of the plastic film bag under the action of the material gravity.

[0079] In this embodiment, a plastic film detector 520 is arranged above the plastic film roll 510 for detecting the quality of the plastic film roll 510. The plastic film detector 520 detects the quality of the plastic film roll 510 and timely discovers the defects and problems in the plastic film.

[0080] Please refer to Figure 7, in some embodiments, the tape compaction mechanism 560 includes a bottom plate 566, on which two mounting plates 561 are fixedly installed. The two mounting plates 561 are arranged oppositely, and sliding grooves 564 are formed on their opposite sides. A sliding rod 563 is slidably connected between the two sliding grooves 564. A pressing roller 562 is rotatably arranged on the sliding rod 563. One side of the pressing roller 562 is in contact with the bonding part of the plastic film bag sleeved on the medicine injection tube 307. The pressing roller 562 is arc-shaped and matches the medicine injection tube 307, and is used for pressing the tape on the plastic film bag. One side inside the sliding groove 564 is provided with a first spring 565, which is used to push the pressing roller 562 to be in close contact with the bonding part of the plastic film bag tape.

[0081] When the plastic film bag passes through the pressing roller 562, due to the action of the first spring 565, the sliding rod 563 is pushed to slide in the sliding groove 564, so that the pressing roller 562 is in close contact with the bonding part of the plastic film bag tape. The pressing roller 562 is arc-shaped and matches the medicine injection tube 307. During the descending process of the plastic film bag, the pressing roller 562 performs rolling compaction on the tape on the plastic film bag, so that the tape is firmly adhered to the plastic film bag. The pressing action of the pressing roller 562 on the tape ensures the sealing quality of the side of the plastic film bag, prevents material leakage, and improves the packaging quality of the product.

[0082] Please refer to Figure 8 , in some embodiments, the plastic film damping mechanism 570 includes a finger clamping cylinder 571. Clamping blocks 572 are fixedly installed on the inner sides of the two finger claws of the finger clamping cylinder 571. The two clamping blocks 572 match the medicine injection tube 307, and the finger clamping cylinder 571 is used to control the two clamping blocks 572 to clamp the medicine injection tube 307 to slow down the descending rate of the plastic film bag.

[0083] After receiving the control signal, the finger clamping cylinder 571 controls the two finger claws on it to contract inward or expand outward. When the finger claws contract inward, the clamping blocks 572 fixedly installed on the inner sides of the finger claws come into contact with the medicine injection tube 307 and clamp the medicine injection tube 307. By adjusting the clamping force of the finger clamping cylinder 571, the damping effect of the clamping blocks 572 on the plastic film bag on the medicine injection tube 307 can be controlled, and the descending rate of the plastic film bag can be slowed down. The plastic film damping mechanism 570 can effectively slow down the descending rate of the plastic film bag, make the filling and sealing processes more stable, and avoid problems such as uneven filling and insecure sealing caused by the too fast descending of the plastic film bag.

[0084] Please refer to Figures 9 - 10, in some embodiments, the traction mechanism 700 includes a telescopic cylinder 701. A connecting plate 702 is installed at the end of the telescopic rod of the telescopic cylinder 701. The connecting plate 702 is arranged in a "7" shape. A traction block 703 is provided on one side of the connecting plate 702. A traction hole 706 is hollowly formed in the traction block 703. A plurality of traction plates 704 are rotatably connected inside the traction hole 706 in a circumferential array manner. A second spring 705 is provided between the traction plate 704 and the inner wall of the traction hole 706, so that the other end of the traction plate 704 contacts the plastic film bag. The end of the traction plate 704 in contact with the plastic film bag is arranged in an arc shape. When in use, the telescopic cylinder 701 contracts to drive the connecting plate 702 to move upward, and then drives the traction block 703 to move upward. The traction plate 704 compresses the second spring 705 and moves upward along the surface of the plastic film bag. When the telescopic cylinder 701 extends, it drives the traction block 703 to move downward through the connecting plate 702. The second spring 705 elastically pushes one end of the traction plate 704 to closely contact the plastic film bag. Driven by the frictional force, the plastic film bag is pulled downward to achieve the traction effect of the plastic film bag after encapsulation.

[0085] Please refer to Figure 11 , in some embodiments, a conveying mechanism 800 is provided below the traction mechanism 700 for conveying the emulsified explosive after encapsulation. The conveying mechanism 800 includes a second conveyor belt 801. A fourth motor 802 is provided on one side of the second conveyor belt 801 for driving the second conveyor belt 801 to convey and transporting the emulsified explosive after encapsulation. The second conveyor belt 801 is installed on a mounting seat 803.

[0086] The fourth motor 802 drives the second conveyor belt 801 to convey. When the emulsified explosive after encapsulation is pulled onto the second conveyor belt 801, the second conveyor belt 801 transports it to a designated position to complete the entire encapsulation and transportation process.

[0087] When an automatic emulsified explosive encapsulation device with a safety protection mechanism is in use, the emulsified explosive material to be encapsulated enters the first conveyor belt 101 of the conveyor 100 through the feed bin 102. The first conveyor belt 101 rotates driven by a motor, conveying the material from the feed end to the discharge end. At the same time, an ion blower 910 located above the conveyor 100 blows ion wind to eliminate the static electricity on the surface of the material. The material falls into the stirring tank 201 of the stirring and defoaming machine 200 by gravity;

[0088] The first motor 205 starts, driving the main gear 211 inside the gear transmission box 210 to rotate. The main gear 211 meshes with the secondary gears 212 on both sides. The secondary gears 212 drive the stirring rod 203 to rotate inside the stirring tank 201 through the connecting rod 213. The serrated teeth 204 on the stirring rod 203 cut the bubbles in the material during rotation, accelerating the rupture and elimination of the bubbles. At the same time, the temperature sensor 925 inside the stirring tank 201 monitors the material temperature in real time. When the temperature exceeds the set value, the cooling water circulation machine 920 starts, and transports the cooling water through the water inlet pipe 921 to the cooling pipe 923 spirally wound inside the cooling jacket 924 of the stirring tank 201. After taking away the heat, the cooling water flows back to the cooling water circulation machine 920 through the water outlet pipe 922 for cooling treatment and is recycled. The material after stirring and degassing flows out through the discharge port 202 at the lower end of the stirring tank 201. The control valve 930 controls the opening and closing of the discharge port 202 and the material flow rate as needed, so that the material is transported to the spiral filling machine 300 at an appropriate speed and quantity;

[0089] After the material enters the bin 301 of the spiral filling machine 300 from the discharge port of the stirring and defoaming machine 200, it first undergoes preliminary material distribution by two spiral distributors 302 to evenly distribute the material. The distributed material falls onto the horizontal medicine-feeding screw 303. The second motor 304 drives the horizontal medicine-feeding screw 303 to rotate horizontally inside the bin 301, transporting the material to the discharge port of the bin 301. At the discharge port of the bin 301, the material enters the medicine-injection pipe 307. The third motor 306 drives the medicine-injection screw 305 inside the medicine-injection pipe 307 to rotate, and accurately fills the material into the material plastic film bag located outside the medicine-injection pipe 307;

[0090] At the same time, the plastic film on the plastic film roll 510 is guided and transported to the inside of the plastic film former 540 through the film guiding mechanism 530. The medicine-injection pipe 307 is arranged inside the plastic film former 540. When the plastic film passes between the medicine-injection pipe 307 and the plastic film former 540, it is shaped by the plastic film former 540 to form a plastic film bag sleeved on the surface of the medicine-injection pipe 307. The tape roll 550 on the plastic film bag sealing side of the plastic film former 540 contacts the sealing part of the plastic film bag through the tape roll roller 551, pastes the tape on the side of the plastic film bag to achieve preliminary sealing. The tape compaction mechanism 560 compresses the adhered tape. The finger clamping cylinder 571 of the plastic film damping mechanism 570 controls the clamping block 572 to clamp the medicine-injection pipe 307, and controls the damping effect of the clamping block 572 on the plastic film bag on the medicine-injection pipe 307 by adjusting the clamping force, slowing down the descending rate of the plastic film bag, and making the filling and sealing process more stable;

[0091] After filling, the plastic film bag descends to the card punching machine 600 under the action of gravity. The card punching machine 600 punches and seals it to close the plastic film bag. The telescopic rod of the telescopic cylinder 701 drives the connecting plate 702 to perform telescopic motion. When the telescopic rod extends, the traction block 703 approaches the plastic film bag, and the traction plate 704 in the traction hole 706 contacts the plastic film bag under the action of the second spring 705. When the telescopic rod retracts, the traction plate 704 generates frictional force on the plastic film bag and pulls the plastic film bag to move downward.

[0092] During the whole process, the electrical control box 400 is electrically connected to each mechanism in the device through the built-in control system and circuit. According to the preset program and logic, it sends control signals to each mechanism, adjusts their operating parameters, and at the same time receives the feedback of the operating status of each mechanism to realize the automatic control of the coordinated work among the mechanisms of the device.
