Description

Technical Field

[0001] This invention relates to the field of insulating paperboard technology, specifically to a pulp feeding control device and its adjustment system for insulating paperboard production. Background Technology

[0002] Insulating paperboard is a material used for electrical insulation, typically made from cellulose pulp. It possesses excellent insulation properties and mechanical strength, and is commonly used as an insulating material in electrical equipment and appliances, for wrapping wires, cables, and insulating conduits. Insulating paperboard is refined from high-purity unbleached sulfate softwood pulp, exhibiting high mechanical strength, good electrical properties, high density, low shrinkage, and a small compression coefficient. It is widely used as an excellent solid insulating material in power transmission and transformation equipment such as oil-immersed transformers, reactors, and instrument transformers. In the process of making insulating paperboard, the first step is to feed material into the distributor. Traditionally, this is done manually by controlling the existing device, which usually involves visual observation to control the amount of material. However, due to the large margin of error in human observation, it is impossible to guarantee the amount of material fed into the distributor. This can lead to too much or too little material inside the distributor. If there is too much material, it will increase the load on the agitator inside the distributor, resulting in uneven mixing of the material. At the same time, when discharging, the presence of residual lumpy particles in the material can cause the filter plate to become clogged when filtered. Under the impact of the material, the filter plate can easily loosen or detach, leading to material leakage and losses.

[0003] Meanwhile, the material generally absorbs a large amount of moisture. If it is not properly dehydrated in time, it will cause the material to flow during transportation, resulting in material loss. At the same time, when the material is discharged, it is impossible to control the uniformity of the discharge amount, which will lead to uneven material content. This will result in inconsistent sizes when making insulating paperboard, affecting the quality of the insulating paperboard.

[0004] Therefore, a pulp feeding control device and its adjustment system for insulating paperboard production are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a pulp feeding control device and its adjustment system for the production of insulating paperboard, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a pulp feeding control device for insulating paperboard production, comprising a base, a feeding box, a pulp distributor, and a flow guiding hose.

The flow guiding hose is arranged in a ring array and fixedly connected between the feeding box and the pulp distributor. The feeding box is equipped with a feeding component for uniformly feeding the pulp.

[0009] Preferably, the uniform discharge assembly includes a storage box fixedly connected to the upper surface of the bottom end of the base. A third spring telescopic rod is symmetrically fixedly connected inside the storage box. A first pressing plate is fixedly connected to the top end of the third spring telescopic rod. A feeding plate is fixedly connected to the bottom end of the first pressing plate. A toothed plate is fixedly connected to the side of the feeding plate near the discharge pipe. A discharge inclined plate is fixedly connected to the side of the storage box away from the discharge pipe.

[0010] Preferably, the pressing assembly includes four electric transmission wheels symmetrically rotatably connected to the bottom end of the base. A conveyor belt is connected between the electric transmission wheels. A first fixing rod is rotatably connected to each electric transmission wheel on the same side. A locking plate is rotatably connected to the middle of each first fixing rod. A torsion spring is fixedly connected to the side of each locking plate near the electric transmission wheel, and the end of each torsion spring away from the locking plate is fixedly connected to the first fixing rod. A first sliding groove is formed on the end of each locking plate away from the first fixing rod. A second fixing rod is slidably connected inside each first sliding groove. A second abutment plate is fixedly connected to the top of each second fixing rod. Electric telescopic plates are symmetrically fixedly connected to the upper surface of the bottom end of the base. A second pressing plate is fixedly connected between the output shafts of the retractable plates. A first fixing plate is fixedly connected between the bottoms of the two electric telescopic plates. An electric button is installed in the middle of the upper surface of the first fixing plate. A third fixing rod is symmetrically rotatably connected to the side wall of the second pressing plate. A grooved plate is symmetrically fixedly connected to the upper surface of the second pressing plate. A second spring block is symmetrically fixedly connected to the bottom of the inner cavity of each grooved plate. A first sliding plate is fixedly connected to the top of each second spring block. The first sliding plate slides vertically inside the grooved plate. An irregular groove is opened on the side of the first sliding plate near the third fixing rod. A second fixing plate is fixedly connected to the upper surface of each first sliding plate. The end of the second fixing plate away from the grooved plate is fixedly connected to the side wall of the first pressing plate.

[0011] Preferably, the automatic telescopic rod is sleeved with the first spring, and the size of the piston baffle is adapted to the size of the feeding box.

[0012] Preferably, the dimensions of the second fixing rod are adapted to the dimensions of the first sliding groove.

[0013] Preferably, the gear plate meshes with the toothed plate, and the size of the scraper is adapted to the size of the filter tank plate.

[0014] Preferably, the size of the feeding plate is adapted to the size of the storage box.

[0015] Preferably, the top of the irregular groove is provided with a slot, the top of the third fixing rod is provided with a sliding rod, and the size of the sliding rod of the third fixing rod is adapted to the size of the irregular groove. The electric transmission wheel is driven and mounted on the first built-in drive device, and the first built-in drive device installed inside the electric transmission wheel is electrically connected to the power supply of the equipment. The electric telescopic plate is mounted on the second built-in drive device, and there is an electrical connection between the second built-in drive device of the electric telescopic plate and the electric button.

[0016] Preferably, the conveyor belt 82 has an elastic function that can deform.

[0017] The pulp feeding and conditioning system for insulating paperboard production includes the following steps:

[0018] S1: The operator feeds material into the feeding box, allowing the material to enter the inside of the distributor through the gap between the piston baffle and the feeding box;

[0019] S2: After the material enters the distributor, it is stirred and mixed by the stirring device to increase the uniformity of the material mixture;

[0020] S3: Subsequently, the mixed material inside the distributor enters the storage tank through the discharge pipe, where it is filtered to remove residues through the filter plate.

[0021] S4: After the material enters the storage box, the operator manually presses down the first pressing plate, so that the material inside the storage box falls into the top of the conveyor belt through the feeding plate and the discharge ramp. At the same time, the operator powers on the built-in drive device of the electric conveyor wheel, which then starts to rotate.

[0022] S5: When the conveyor belt moves the material to the top of the second contact plate, the conveyor belt moves downward to touch the second contact plate, which in turn causes the second contact plate to touch the electric button to control the built-in drive device of the electric telescopic plate to be energized, thereby causing the electric telescopic plate to start reciprocating.

[0023] S6: When the electric telescopic plate starts working, it drives the first pressing plate to discharge material intermittently, and at the same time drives the second contact plate to dehydrate the material above the conveyor belt.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. The piston baffle blocks a certain amount of material under the elastic action of the first spring, thus achieving the purpose of automatic quantitative feeding. This avoids the problem of material blockage when too much material is fed into the distributor. In addition, it further reduces the load on the mixing device inside the distributor, thereby avoiding damage to the mixing device due to long-term load operation. This not only improves the uniformity of material mixing inside the distributor, but also ensures the service life of the mixing device.

[0026] 2. The scraper rotates inside the filter plate to clean the residue adhering to the filter position, preventing excessive residue from affecting the material discharge effect and further preventing the filter plate from becoming clogged. In addition, it also avoids the impact between the filter plate and the material when the filter plate is clogged, and further prevents the connection between the filter plate and the discharge pipe from breaking and falling off. It also prevents residue from entering the storage box through the connection between the filter plate and the discharge pipe, which not only reduces the residue content inside the insulating paperboard, but also improves the quality of the insulating paperboard.

[0027] 3. The electric telescopic plate drives the second pressing plate to dehydrate the material on the upper surface of the conveyor belt, which avoids the problem of excessive moisture in the material flowing during transportation. In addition, it further prevents the material from flowing away from the conveyor belt and causing material loss during transportation, thereby improving the stability of the material transportation process and reducing the working cost after material loss.

[0028] 4. The uniform movement of the first pressing plate causes the material inside the storage box to be quantitatively fed onto the conveyor belt through the discharge inclined plate, ensuring the consistency of the material feeding amount and avoiding the situation where too much or too little material is fed onto the surface of the conveyor belt. In addition, it prevents the uneven material conveyed by the conveyor belt from causing the insulation paperboard to be of different sizes, further ensuring the qualification rate of the insulation paperboard and thus improving the production efficiency of the insulation paperboard.

[0057] Example 2

[0058] The pulp feeding and conditioning system for insulating paperboard production includes the following steps:

[0059] S1: The operator feeds material into the feed box 2, so that the material enters the inside of the distributor 3 through the gap between the piston baffle 63 and the feed box 2.

[0060] S2: After the material enters the distributor 3, it is stirred and mixed by the stirring device to increase the uniformity of the material mixture;

[0061] S3: Subsequently, the material that has been mixed inside the distributor 3 enters the storage tank 71 through the discharge pipe 51, and the residue is filtered by the filter plate 52.

[0062] S4: When the material enters the storage box 71, the operator manually presses down the first pressing plate 73, so that the material inside the storage box 71 falls into the top of the conveyor belt 82 through the feeding plate 74 and the discharge inclined plate 76. At the same time, the operator powers on the built-in drive device of the electric conveyor wheel 81, so that the electric conveyor wheel 81 starts to rotate.

[0063] S5: When the conveyor belt 82 moves the material to the top of the second contact plate 88, the conveyor belt 82 moves downward against the second contact plate 88, which in turn causes the second contact plate 88 to contact the electric button 812 to control the built-in drive device of the electric telescopic plate 89 to be energized, thereby causing the electric telescopic plate 89 to start reciprocating.

[0064] S6: When the electric telescopic plate 89 starts working, it drives the first pressing plate 73 to discharge material intermittently, and at the same time drives the second contact plate 88 to dehydrate the material above the conveyor belt 82.

[0065] The following describes the working process and principle of the above embodiments:

[0066] The initial state is as follows: the automatic telescopic rod 61 is not retracted, the first spring 62 is not retracted, the third spring telescopic rod 72 is not retracted, the second spring block 815 is not retracted, and the torsion spring 85 is in a relaxed state.

[0067] The working steps are as follows: At the start of the operation, the operator feeds material into the feeding box 2 until it is full. As the amount of material inside the feeding box 2 increases, the piston baffle 63 moves vertically downward inside the feeding box 2 under the pressure of the material. This causes the piston baffle 63 to retract downward against the extension axis of the automatic telescopic rod 61. At the same time, the first spring 62 retracts downward synchronously under the action of the piston baffle 63. When the piston baffle 63 moves downward and separates from the inner wall of the feeding box 2, the material inside the feeding box 2 enters the first spring 62 through the gap between the piston baffle 63 and the feeding box 2. At the bottom of spring 62, the material then enters the interior of distributor 3 through guide hose 4. Under the elastic action of the first spring 62, the piston baffle 63 blocks a certain amount of material, achieving the purpose of automatic quantitative feeding. In addition, it avoids the problem of material blockage when too much material is fed into distributor 3. Furthermore, it further reduces the load on the stirring device inside distributor 3, thereby avoiding damage to the stirring device due to long-term load operation. This not only improves the uniformity of material mixing inside distributor 3, but also ensures the service life of the stirring device.

[0068] After the distributor 3 fully mixes the fed material, the mixture inside the distributor 3 enters the discharge pipe 51, then passes through the filter plate 52 and enters the storage tank 71, accumulating at the bottom of the feeding plate 74. When the material enters the feeding plate 74, the operator quickly presses down the first pressing plate 73 once, causing the first pressing plate 73 to compress the third spring telescopic rod 72 and retract. Simultaneously, the first pressing plate 73 drives the feeding plate 74 to move vertically downward inside the storage tank 71. When the bottom of the first pressing plate 73 moves to the same horizontal plane as the discharge ramp 76, the material at the top of the first pressing plate 73 enters the discharge ramp 76 through the ramp set on the first pressing plate 73. During the process of the first pressing plate 73 driving the feeding plate 74 to move vertically downward inside the storage tank 71, the feeding plate 74 drives the toothed plate 75 to move vertically downward inside the storage tank 71 simultaneously. The movement causes the toothed plate 75 to drive the meshing gear plate 54 to rotate inside the filter tank plate 52. At this time, the gear plate 54 drives the first contact block 55 to abut against the top of the scraper 53, causing the scraper 53 to rotate around the center of the filter tank plate 52. The scraper 53 rotates inside the filter tank plate 52 to clean the residue attached to the filter position of the filter tank plate 52, avoiding the impact of excessive residue on the material discharge effect. It further prevents the filter tank plate 52 from clogging due to excessive residue. In addition, it also avoids the impact between the filter tank plate 52 and the material when the filter tank plate 52 is clogged. It further prevents the connection between the filter tank plate 52 and the discharge pipe 51 from breaking and falling off. It further prevents the residue from entering the storage box 71 through the connection between the filter tank plate 52 and the discharge pipe 51. This not only reduces the residue content inside the insulating paperboard, but also improves the quality of the insulating paperboard.

[0069] When the operator presses down on the first pressing plate 73, the first pressing plate 73 causes the second fixing plate 818 to move vertically downwards simultaneously. This, in turn, causes the second fixing plate 818 to cause the first sliding plate 816 to move vertically downwards inside the groove plate 814. The first sliding plate 816 then causes the irregularly shaped groove 817 to move downwards and compress the second spring block 815, causing it to contract. During the downward movement of the irregularly shaped groove 817, it abuts against the sliding rod at the top of the third fixing rod 813, causing the sliding rod on the third fixing rod 813 to rotate counterclockwise inside the irregularly shaped groove 817. The sliding mechanism, under the resistance of the irregular groove 817, drives the third fixing rod 813 to rotate around its bottom. When the third fixing rod 813 moves to the top of the irregular groove 817, the operator stops pressing the first pressing plate 73, causing the first sliding plate 816 to move vertically upward inside the groove plate 814 under the elastic action of the extended second spring block 815. At this time, the sliding mechanism of the third fixing rod 813 slides into the groove opened at the top of the irregular groove 817 under the resistance of the irregular groove 817, and the third fixing rod 813 engages with the first sliding plate 816.

[0070] When the material at the top of the first pressing plate 73 enters the interior of the discharge ramp 76, it flows through the ramp inside the discharge ramp 76 onto the upper surface of the conveyor belt 82. Simultaneously, the operator powers on the built-in drive unit inside the electric conveyor wheel 81, causing it to rotate slowly and synchronously on the top of the base 1. This, in turn, causes the electric conveyor wheel 81 to drive the conveyor belt 82 to rotate slowly and synchronously. When the material on the upper surface of the conveyor belt 82 moves above the second contact plate 88, it presses down on the conveyor belt 82 due to its own gravity, causing the conveyor belt 82 to contact the second contact plate 88. Simultaneously, the second contact plate 88 slides through the second fixing rod 87 inside the first chute 86 while contacting the locking plate 84. This causes the locking plate 84 to rotate downwards around the first fixing rod 83, causing the locking plate 84 to drive the torsion spring 85 to rotate and generate elastic force. As the second contact plate 88 moves downwards, it... Pressing the electrical button 812 downwards activates the built-in drive device of the electric telescopic plate 89, which in turn powers the equipment. This causes the electric telescopic plate 89 to rapidly extend vertically upwards. As the output shaft of the electric telescopic plate 89 extends vertically, it drives the second pressing plate 810 to move vertically back and forth, pressing the material on the upper surface of the conveyor belt 82. This causes some of the moisture inside the material to be removed. Once the moisture is removed, the material's weight decreases, preventing it from pressing the conveyor belt 82 and pressing the electrical button 812. By using the electric telescopic plate 89 to drive the second pressing plate 810 to dehydrate the material on the upper surface of the conveyor belt 82, the material is prevented from flowing during transportation due to excessive moisture. Furthermore, this prevents the material from flowing away from the conveyor belt 82 and causing material loss, thus improving the stability of the material during transportation and reducing the operating costs after material loss.

[0071] When the electric telescopic plate 89 drives the second pressing plate 810 to move up and down reciprocally, the second pressing plate 810, through the engagement of the third fixing rod 813 with the first sliding plate 816, drives the second fixing plate 818 to move up and down reciprocally. This causes the second fixing plate 818, through the first pressing plate 73, to drive the feeding plate 74 to move up and down reciprocally inside the storage box 71. Consequently, the feeding plate 74 causes the material fed from the top to flow intermittently into the discharge inclined plate 76, thus allowing the discharge inclined plate 76 to uniformly feed material onto the conveyor belt 82. The uniform movement of the first pressing plate 73 ensures that the material inside the storage box 71 is quantitatively fed onto the conveyor belt 82 through the discharge inclined plate 76, guaranteeing the consistency of the material feeding amount and preventing the material fed onto the upper surface of the conveyor belt 82 from being too much or too little. In addition, it prevents uneven material conveyed by the conveyor belt 82 from causing inconsistent sizes of the insulating paperboard, further ensuring the qualification rate of the insulating paperboard and thus improving the production efficiency of the insulating paperboard.
