Description

Technical Field

[0001] This invention relates to the field of high-voltage fuse manufacturing and processing technology, specifically to a high-voltage fuse manufacturing and forming processing device. Background Technology

[0002] High-voltage fuses are important overload and short-circuit protection devices in power systems. Their core structure consists of a fusible element encapsulated within a porcelain insulating tube (referred to as a porcelain tube or porcelain insulator), surrounded by silica sand as an arc-extinguishing and heat-conducting medium. The quality of the silica sand, especially its filling density, uniformity, and appropriate particle size distribution, directly determines the fuse's breaking capacity, current-limiting characteristics, and long-term operational stability.

[0003] Currently, the industry generally uses gravity-feeding or single-station vibration filling methods for quartz sand filling, which mainly have the following technical defects: 1. Lack of segmented and precise filling capability, and unreasonable filling structure. Most existing equipment uses single-size quartz sand for one-time filling, or mentions coarse and fine sand but does not achieve true segmented independent control. This makes it difficult for fine sand (0.1-0.3mm) to fully fill the narrow gaps around the melt, easily forming voids, bridging, or delamination; and if the upper support area is not filled properly, it is prone to settling under transportation or short-circuit impact, causing the melt to be exposed, which seriously affects the arc extinguishing performance and electrical safety of the product.

[0004] 2. Currently, the connection between the sand discharge port and the ceramic tube mostly uses a simple static seal. During vibration compaction, sand particles can easily splash out from the gaps, causing raw material waste and pollution to the production environment. At the same time, the remaining material after filling is often directly discarded, lacking an effective automatic recycling system, resulting in low raw material utilization and failing to meet the environmental protection and safety production requirements of modern manufacturing.

[0014] Preferably, the backpressure machine includes a mounting frame, which is installed on the top of the first side box.

One end of the backpressure pipe extends into the air return hole of the middle box, and the air return hole is located above the soft pad. A second rack that cooperates with the first gear is fixedly installed on the top of the soft pad.

[0015] The first sealing plate has a high-precision pressure sensor embedded inside, and its detection signal is transmitted to an external controller to form a closed-loop control with the conveyor motor. When the real-time weight W of the sand intercepted at the top of the first sealing plate is less than the preset fine sand target value Wfine, the controller increases the speed of the conveying motor, drives the conveying screw conveyor shaft to accelerate downward to feed the fine sand, so that the sand is continuously fed into the porcelain bottle through the feeding hole of the storage cylinder; when W approaches Wfine, the conveying motor switches to low speed operation; when Wfine is Wfine, the conveying motor stops, cutting off the sand flow.

[0016] At the same time, the vibrating hydraulic rod periodically strikes the vibrating component, causing the fine sand inside the porcelain bottle to further compact and settle under vibration; the pressure sensor monitors the change in sand weight in real time. If the W value drops due to settling, the controller restarts the conveying screw shaft to replenish sand in small amounts until the weight stabilizes within the range, ensuring that the fine sand layer is filled with a consistent height and that no molten material is exposed.

[0017] The second sealing plate is also equipped with a pressure sensor, whose signal forms an independent closed loop with the conveyor motor. When the weight of the sand at the top of the second sealing plate, W (coarse measurement), is less than the target value of coarse sand, W (coarse), the conveying motor drives the conveying screw shaft to rotate in the forward direction, quickly pushing the coarse sand in the storage cylinder into the middle box, and pouring it into the upper part of the porcelain bottle through the feeding hole; when W (coarse measurement) reaches % of W (coarse), the conveying motor automatically reduces its speed to avoid overshoot; when W (coarse measurement) reaches W (coarse), the conveying motor immediately stops.

[0018] During the coarse sand filling process, the vibrating hydraulic rod excites the ceramic bottle with high frequency and small amplitude, prompting it to quickly form a uniform support layer; after filling is completed, the conveying motor briefly reverses, driving the return screw conveyor shaft to send the remaining coarse sand in the feeding hole back to the storage cylinder for recycling through the inlet pipe return material outlet pipe.

[0019] This invention provides a high-voltage fuse manufacturing and forming apparatus, which has the following beneficial effects: 1. This invention adopts a segmented precision filling structure of fine sand first and then coarse sand, which enables the molten area inside the ceramic tube to be tightly wrapped and densely filled with 0.1-0.3mm fine sand, while the upper non-functional area is quickly filled and supported with 0.3-0.5mm coarse sand. This effectively improves the density and uniformity of the quartz sand filling, avoids defects such as voids, bridging, and delamination, significantly enhances the arc extinguishing capability and current limiting performance of the fuse, and improves the electrical performance and operational stability of the product. 2. This invention uses the rack and gear mechanical linkage on the clamp to automatically start negative pressure suction and expel air from inside the ceramic tube when it is inserted. After filling, it automatically returns to normal pressure. No additional electrical control drive and sensor control are required. This ensures that the fine sand filling is more compact and avoids the sand layer from loosening, falling off or being sucked out due to negative pressure, which greatly improves filling stability and product yield. 3. The first sealing plate, the middle box, the feeding plate and the feeding hole work together to form a closed storage and quantitative feeding structure. After the porcelain bottle is removed, it effectively prevents the quartz sand from falling and spilling accidentally, ensuring that the equipment table is clean and the production environment is dust-free, while avoiding the waste of sand. 4. This invention uses a roll-type baffle with a feeding plate and feeding hole to achieve sealed quantitative feeding. Combined with a return material machine and a return material screw conveyor shaft, it forms an automatic sand circulation system, which allows excess sand to automatically flow back to the storage cylinder for reuse, achieving no spillage, no residue, and no dust overflow, greatly reducing raw material loss, improving raw material utilization, and improving the production environment to meet environmental protection and safe production requirements. 5. The present invention adopts a differentiated structural design for the fine sand filler assembly and the coarse sand filler assembly. The fine sand station is equipped with a negative pressure and back pressure system to ensure compaction, while the coarse sand station has a simplified structure to improve filling efficiency. It takes into account both the compaction requirements of fine sand and the rapid filling requirements of coarse sand, thereby improving the overall production cycle, increasing equipment capacity, and reducing energy consumption and production costs. 6. By installing pressure sensors inside the first and second sealing plates, the real-time weight of the sand intercepted above the sealing plates is detected, and a closed-loop linkage control is formed with the conveying screw shaft. This enables precise quantitative supply and filling of quartz sand, ensuring that the amount of sand falling into the ceramic tube is consistent in height and uniform in weight each time. This effectively avoids overfilling, underfilling, and leakage, further improving the filling consistency and filling accuracy of the same batch of products, and enhancing the quality stability of fuse products. 7. This invention sets a top buffer ring and an outer buffer ring at the upper and lower interfaces of the ceramic tube for vibration reduction and buffering. Combined with an adaptive clamping fixture and a purely mechanical transmission structure, it can effectively block the impact of vibration on the ceramic tube, prevent the ceramic tube from breaking, improve the equipment's dust resistance and interference resistance, reduce the failure rate, extend the service life of the equipment, and is compatible with filling ceramic tubes with multiple specifications of fuses, thereby improving the equipment's versatility and production changeover speed.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] Please see Figures 1 to 12 The present invention provides a technical solution: a high-voltage fuse production and forming processing device, including a base 1, a plurality of clamps 6 installed on the surface of the base 1, a fine sand filler assembly 4 installed on the fine sand assembly station on the surface of the base 1, and a coarse sand filler assembly 5 installed on the coarse sand assembly station on the surface of the base 1. Both the fine sand packing assembly 4 and the coarse sand packing assembly 5 include a packing machine 7. The packing machine 7 includes a middle box 706. A first side box 703 is fixedly installed on the left side of the middle box 706. A first winding box 702 is fixedly installed at the left end of the first side box 703. A second side box 704 is fixedly installed at the right end of the middle box 706. A second winding box 705 is fixedly installed at the right end of the second side box 704. A first winding roller 720 is rotatably connected inside the first winding box 702 via a bearing. A second winding roller 725 is rotatably connected inside the second winding box 705 via a bearing. A baffle roll 2 is wound around the outside of the first winding roller 720 and the second winding roller 725. The baffle roll 2 includes a soft pad 201. Both ends of the soft pad 201 are fixedly connected to the outer sides of the first take-up roller 720 and the second take-up roller 725, respectively. A feeding plate 204 is embedded in the top of the soft pad 201. Each feeding plate 204 has a feeding hole 205 on its top. A top buffer ring 206 is embedded in the bottom of the soft pad 201 and below the feeding hole 205. A first sealing plate 202 is embedded on the surface of the soft pad 201 on the fine sand filler assembly 4 and on the left side of the feeding plate 204. An injection pipe 203 is installed inside the first sealing plate 202. A rotary joint 726 is installed on the front surface of the first winding box 702. The injection pipe 203 passes through the soft pad 201 and is connected to one end of the first winding roller 720 and the rotary joint 726. A negative pressure machine 9 is fixedly installed at the bottom of the first side box 703, and a back pressure machine 8 is fixedly installed at the top of the first side box 703. A second sealing plate 207 is embedded on the surface of the soft pad 201 on the coarse sand filler assembly 5 and on the left side of the feed plate 204.

[0024] The feeding plate 204 moves with the soft pad 201, forming an openable and closable sealed channel between the middle box 706 and the porcelain bottle 607. When not filled, the sealing plates 202 / 207 seal the bottom of the middle box 706 to prevent sand from spilling. The top buffer ring 206 fits against the mouth of the porcelain bottle 607 during filling, absorbing the impact transmitted by the vibrating hydraulic rod 701 and reducing the breakage rate of the porcelain bottle 607 to below 0.01%. The first sealing plate 202 of the fine sand filler assembly 4 has an internal injection pipe 203, which is connected to the negative pressure machine 9 and the return pressure machine 8 via a rotary joint 726. When the porcelain bottle 607 is inserted, the negative pressure machine 9 draws air from the bottle through the injection pipe 203 to form a negative pressure of -0.05-0.08MPa, which helps the fine sand penetrate into the gap of the melt. After filling is completed, the return pressure machine 8 injects air into the bottle to restore normal pressure, so as to prevent the sand layer from loosening due to continuous negative pressure.

[0025] The second sealing plate 207 of the coarse sand filler assembly 5 only needs to work with the baffle roll 2 to complete the feeding, without the need for a negative pressure / back pressure system, and utilizes the high fluidity of coarse sand to achieve rapid filling; Furthermore, a storage cylinder 707 is fixedly installed on the top of the middle box 706, and a mounting base 710 is fixedly installed on the inner wall of the discharge pipe at the bottom of the storage cylinder 707. The top of the mounting base 710 is rotatably connected to the top of the inner cavity of the storage cylinder 707 via a bearing, and a conveying screw conveyor shaft 711 is fixedly installed on the top of the storage cylinder 707. The bottom end of the conveying screw conveyor shaft 711 extends to the bottom of the mounting base 710. A transmission box 709 is fixedly installed on the top of the transmission box 709, and a conveying motor 708 is fixedly installed on the top of the transmission box 709. The top end of the conveying screw conveyor shaft 711 extends into the transmission box 709. The output end of the conveying motor 708 is connected to the top end of the conveying screw conveyor shaft 711 via a coupling. An inlet pipe 724 is fixedly installed at the bottom of the middle box 706, and an outer buffer ring 723 is fixedly fitted on the inner side of the inlet pipe 724.

[0026] Those skilled in the art will know that the above structure mainly addresses how to achieve stable storage, quantitative transportation, and flexible docking with the porcelain bottle 607 for quartz sand.

[0027] Storage cylinder 707 and conveying screw shaft 711 constitute a gravity-screw composite feeding system. Storage cylinder 707 centrally stores quartz sand, and conveying screw shaft 711, driven by conveying motor 708, pushes the sand from the bottom of storage cylinder 707 to the middle box 706 through screw blades, realizing forced conveying and flow control of the sand.

[0028] Access tube 724 and outer buffer ring 723: Access tube 724 serves as the insertion guide channel for porcelain bottle 607. The outer buffer ring 723 fixed inside it is preferably made of polyurethane or rubber elastomer. When porcelain bottle 607 is inserted, it forms radial clamping and axial buffering, which achieves both sealing and absorption of vibration and impact.

[0029] The conveying screw shaft 711 is rotated by adjusting the speed of the conveying motor 708, and the pressure sensor in the sealing plate 202 / 207 provides feedback to achieve closed-loop control and solve the problems of overfilling and underfilling.

[0030] Screw conveyors overcome the discontinuity problem of pure gravity material feeding, ensuring a continuous and uniform sand flow and avoiding uneven filling density caused by fluctuations in material supply.

[0031] The outer buffer ring 723 and the top buffer ring 206 form a double-end flexible clamp, absorbing more than 80% of the impact energy transmitted by the vibration hydraulic rod 701, reducing the breakage rate of the porcelain bottle 607, and extending the service life of equipment and products.

[0032] Furthermore, an inlet pipe 713 is fixedly installed at the bottom of the second side box 704, below the feeding hole 205. A hole is provided at the bottom of the second side box 704 to connect the feeding hole 205 and the inlet pipe 713. A return feeder 714 is fixedly installed at the back of the second side box 704. The outlet of the inlet pipe 713 is connected to the inlet of the return feeder 714. A return feeder screw conveyor shaft 715 is rotatably connected inside the return feeder 714 via bearings. A discharge pipe 716 is fixedly installed at the discharge port. The discharge port of the discharge pipe 716 is connected to the return port at the discharge end of the storage cylinder 707. The top end of the return screw conveyor shaft 715 extends into the transmission box 709. A one-way bearing 717 is installed on the outer side of the top end of the return screw conveyor shaft 715. A sprocket 718 connected by a chain belt drive is fixedly sleeved on the outer side of both the one-way bearing 717 and the conveying screw conveyor shaft 711. A feed valve 712 is fixedly installed at the feed port of the storage cylinder 707.

[0033] Those skilled in the art will know that solving the problem of handling residual sand in the feeding hole 205 after filling can achieve zero spillage and full reuse.

[0034] Inlet pipe 713: connects the bottom of the second side box 704 with the return material machine 714, serving as a transfer channel for residual sand.

[0035] The return feeder 714 and the return feed screw conveyor 715: receive the sand from the inlet pipe 713 and force the sand to be conveyed to the outlet pipe 716 by the screw push of the return feed screw conveyor 715.

[0036] Sprockets 718 and one-way bearings 717: The conveying screw conveyor shaft 711 drives the return screw conveyor shaft 715 through the sprocket 718. The one-way bearings 717 ensure that the return shaft only works when the conveying motor 708 is in reverse return mode, and disengages when in forward feeding mode to avoid interference.

[0037] Outlet pipe 716 and replenishment valve 712: Outlet pipe 716 sends the recovered sand back to the bottom mounting base 710 of storage cylinder 707, and replenishment valve 712 replenishes sand according to the material level of storage cylinder 707; The material return is driven by the reverse rotation of the conveyor motor 708, eliminating the need for an additional power source and reducing system energy consumption; the one-way bearing 717 ensures that the feeding and return modes do not interfere with each other, ensuring reliable operation.

[0038] Furthermore, a first take-up motor 721 is fixedly installed on the back of the first take-up box 702, and the output end of the first take-up motor 721 is connected to one end of the first take-up roller 720 through a coupling. A second take-up motor 722 is fixedly installed on the back of the second take-up box 705, and the output end of the second take-up motor 722 is connected to one end of the second take-up roller 725 through a coupling.

[0039] Those skilled in the art will know that The first take-up motor 721 and the second take-up motor 722 drive the first take-up roller 720 and the second take-up roller 725 respectively, and transmit torque through the coupling to realize the synchronous take-up and untake-up of the soft pad 201.

[0040] Take-up rollers 720 / 725: As the winding carrier for the cushion 201, they determine the stopping position of the feed plate 204 between the middle box 706 and the second side box 704 through precise angular displacement control.

[0041] Precise feeding and positioning: Dual motor servo control, the movement accuracy of the soft pad 201 reaches 0.1mm, ensuring that the feeding hole 205 of the feeding plate 204 is always aligned with the center of the ceramic bottle 607, without misalignment or sand leakage.

[0042] Coordinated operation without pulling: The two winding motors start and stop synchronously, and the tension of the soft pad 201 is constant, avoiding deformation or tearing of the soft pad 201 due to asynchronous winding and unwinding, thus extending the service life of the material stop roll 2.

[0043] Furthermore, the base 1 includes a frame 101, a support frame 102 is fixedly installed on the top of the frame 101, a turntable 103 is rotatably connected to the top of the support frame 102 via a bearing, a rotary motor 104 is fixedly installed in the middle of the support frame 102, the output end of the rotary motor 104 is fixedly connected to the bottom end of the turntable 103, a fixing frame 105 is fixedly installed on the top of the frame 101, a lifting hydraulic rod 106 is fixedly mounted on the top of the fixing frame 105, an installation arm 107 is fixedly installed on the telescopic end of the lifting hydraulic rod 106, the top of the installation arm 107 is fixedly connected to the fine sand filling assembly 4 and the coarse sand filling assembly 5, and both ends of the installation arm 107 extend into the guide grooves at both ends of the fixing frame 105 and are slidably connected to the guide grooves.

[0044] Those skilled in the art will know that the turntable 103 and the rotary motor 104: the turntable 103 is circumferentially arranged with multiple clamps 6, and the rotary motor 104 drives the turntable 103 to rotate step by step, so that the porcelain bottle 607 passes through the fine sand station, the coarse sand station and the unloading station in sequence.

[0045] Lifting hydraulic rod 106 and mounting arm 107: The lifting hydraulic rod 106 drives the fine sand packing assembly 4 and the coarse sand packing assembly 5 to rise and fall synchronously through the mounting arm 107, so as to realize the docking and separation of the packing machine 7 and the porcelain bottle 607.

[0046] Guide groove: The two ends of the mounting arm 107 slide along the guide groove of the fixed frame 105 to restrict its degree of freedom, ensure no swaying during the lifting process, and ensure precise docking.

[0047] The rotary table 103 has 6 clamps arranged radially, and the packing assembly is lifted and lowered in the center, reducing the equipment's footprint and making it suitable for compact workshop layouts.

[0048] Furthermore, the clamp 6 includes a vibrating element 601, which is installed on the outside of the turntable 103. A clamp 603 is fixedly installed on the right end of each vibrating element 601. A fixed base 602 is fixedly installed at the bottom of the clamp 603. A porcelain bottle 607 is placed on the top of each fixed base 602. A clamping cylinder 604 is fixedly mounted on the front surface of each clamp 603. The telescopic end of the clamping cylinder 604 extends to the middle of the clamp 603 and is fixedly connected to the porcelain bottle 607. The position of the porcelain bottle 607 is clamped and fixed by the clamping block 605 and the inner side of the clamp 603. A first rack 606 is fixedly installed on the top of each clamp 603 by a support column.

[0049] Those skilled in the art will know that the fixture 6 includes a vibrating element 601, a clamp 603, and a fixed base 602. The vibrating element 601 receives the impact of the vibrating hydraulic rod 701 and transmits the vibration to the porcelain bottle 607 to promote the compaction of the sand body.

[0050] Clamping cylinder 604 and clamping block 605: Clamping cylinder 604 drives clamping block 605 to clamp porcelain bottle 607, with clamping force adjustable from 0.5-2MPa.

[0051] First rack 606: Fixed to the top of clamp 603, it moves up and down with porcelain bottle 607 and meshes with second gear 907 of negative pressure machine 9, serving as a mechanical trigger signal.

[0052] Vibration direction transmission: The vibrating component 601 converts the impact of the vibrating hydraulic rod 701 into high-frequency micro-vibration of the porcelain bottle 607, which promotes sand settling and increases filling density.

[0053] Passive automatic triggering: The first rack 606 naturally engages with the second gear 907 as it rises and falls, requiring no sensors or electronic control commands, and is plug-and-play; Furthermore, a vibrating hydraulic rod 701 is fixedly installed on the left end of the first winding box 702, and the position of the vibrating hydraulic rod 701 is matched with the position of the vibrating element 601.

[0054] As those skilled in the art will know, the vibration is transmitted only to the porcelain insulator 607 through the vibrating element 601, and absorbed by the outer buffer ring 723 and the top buffer ring 206, without being transmitted to the base 1 or other components, resulting in high overall equipment stability. By adjusting the amplitude and frequency of the vibrating hydraulic rod 701, it can adapt to the different densification requirements of fine sand with low-frequency large amplitude and coarse sand with high-frequency small amplitude.

[0055] Furthermore, the negative pressure unit 9 includes a connecting frame 906, which is assembled at the bottom of the first side box 703. A negative pressure piston cylinder 901 is fixedly installed at the bottom end of the connecting frame 906. A second threaded rod 902 is rotatably connected to the right end of the negative pressure piston cylinder 901 via a bearing. A second piston rod 903 is threadedly connected to the outer side of the second threaded rod 902, and one end of the second piston rod 903 extends into the interior of the negative pressure piston cylinder 901 and cooperates with the interior of the negative pressure piston cylinder 901. The top end is embedded into the rail groove opened at the bottom of the connecting frame 906 and is slidably connected to the inside of the rail groove. The front end of the negative pressure piston cylinder 901 is inlaid with a discharge pipe 904 and a suction pipe 905. One-way valves are fixedly connected to one end of the discharge pipe 904 and the suction pipe 905 located inside the negative pressure piston cylinder 901. One end of the suction pipe 905 is connected to the other end of the rotary joint 726. A second gear 907 is fixedly sleeved on the outer side of the right end of the second threaded rod 902, and the second gear 907 cooperates with the first rack 606.

[0056] Those skilled in the art will know that the negative pressure piston cylinder 901 and the second piston rod 903 constitute a cylinder with variable volume. The movement of the second piston rod 903 changes the internal volume of the cylinder, producing a suction or discharge action.

[0057] The second threaded rod 902 and the second gear 907: The second gear 907 meshes with the first rack 606, converting the linear lifting motion of the porcelain bottle 607 into the rotation of the second threaded rod 902, thereby driving the second piston rod 903 to move linearly.

[0058] Inlet pipe 905 and outlet pipe 904: Inlet pipe 905 is connected to injection pipe 203 via rotary joint 726, and outlet pipe 904 is equipped with a one-way valve, which is responsible for air extraction and air exhaust respectively.

[0059] Furthermore, the back pressure press 8 includes a mounting bracket 804, which is mounted on the top of the first side box 703. A back pressure piston cylinder 807 is fixedly mounted on the top of the mounting bracket 804. The bottom of the back pressure piston cylinder 807 is rotatably connected to a first threaded rod 805 via a bearing. The bottom end of the first threaded rod 805 extends into the interior of the first side box 703 and is fixedly fitted with a first gear 806. A first piston rod 803 is threadedly connected to the outer side of the first threaded rod 805. The top end of the first piston rod 803 extends into the interior of the back pressure piston cylinder 807 and is connected to the back pressure piston cylinder 807. 07 Internal sliding connection, the left end of the first piston column 803 extends into the groove opened on the side of the mounting bracket 804 and slides in the groove. The top of the back pressure piston cylinder 807 is fixedly installed with a suction pipe 808 and a back pressure pipe 801. One-way valves are installed at one end of the back pressure pipe 801 and the suction pipe 808 inside the back pressure piston cylinder 807. One end of the back pressure pipe 801 extends into the air return hole of the middle box 706. The air return hole is located above the soft pad 201. The top of the soft pad 201 is fixedly installed with a second rack 802 that cooperates with the first gear 806.

[0060] Those skilled in the art will know that when the feeding plate 204 is reset, the second rack 802 drives the first gear 806, and the first piston column 803 moves upward to press air into the porcelain bottle 607, instantly restoring normal pressure and preventing the sand layer from loosening or falling off due to prolonged negative pressure.

[0061] The back pressure action is synchronized with the movement of the baffle roll 2, and is triggered only when the feed plate 204 leaves the middle box 706. There are no additional control components, and the structure is simple.

[0062] After back pressure is applied, the internal air pressure of the porcelain bottle 607 is consistent with that of the atmosphere, and there is no sand migration caused by pressure difference, so the filling shape is stable.

[0063] Working principle: First, the porcelain bottle 607 is loaded into the clamp 603. Then, the clamping block 605 is moved by the telescopic end of the clamping cylinder 604. The porcelain bottle 607 is clamped and positioned by the clamping block 605 and the inner wall of the clamp 603, thus completing the loading of the porcelain bottle 607. Fine sand filling process: First, the output end of the rotary motor 104 drives the turntable 103 and the clamp 6 to rotate, so that the porcelain bottle 607 on the clamp 6 rotates to the bottom of the fine sand packing assembly 4. Then, the telescopic end of the lifting hydraulic rod 106 drives the mounting arm 107 to move down, so that the mounting arm 107 drives the fine sand packing assembly 4 and the coarse sand packing assembly 5 to move down. During the downward movement, the top of the porcelain bottle 607 is inserted a certain distance into the bottom of the inlet pipe 724. At this time, the second gear 907 contacts the first rack 606, causing the first rack 606 to move upward and drive the second gear 907 to rotate. This causes the second gear 907 to drive the second threaded rod 902 to rotate. Then, the second threaded rod 902 drives the second piston rod 903 to move towards the second gear 907. The gas inside the middle box 706 and the outer buffer ring 723 is extracted through the injection pipe 203 and enters the rotary joint 726 through the injection pipe 203. Then, it enters the suction pipe 905 through the rotary joint 726 and is sucked into the negative pressure piston cylinder 901 through the suction pipe 905. When the top of the porcelain bottle 607 contacts the bottom of the first sealing plate 202, the first rack 606 is located above the second gear 907. The weight of the sand trapped at the top of the first sealing plate 202 is detected by the pressure sensor inside the first sealing plate 202. The output of the first winding motor 721 drives the first winding roller 720 to rotate, so that the first winding roller 720 winds up the soft pad 201. The output of the second winding motor 722 drives the second winding roller 725 to rotate, so that the second winding roller 725 releases the soft pad 201, thereby pulling the first sealing plate 202 to move into the first side box 703, so that the feeding plate 204 is located inside the middle box 706. During the movement, the soft pad 201 drives the second rack 802 to move toward the first gear 806, which causes the second rack 802 to drive the first gear 806 to drive the first threaded rod 805 to rotate, which causes the first threaded rod 805 to drive the first piston rod 803 to move downward, so that the suction tube 808 draws in air into the back pressure piston cylinder 807. When the second rack 802 disengages from the first gear 806, a certain amount of gas is drawn into the back pressure piston cylinder 807. When the feeding plate 204 moves into the middle box 706, the sand trapped inside the middle box 706 enters the porcelain bottle 607 through the feeding hole 205. Then, the output end of the conveying motor 708 drives the conveying screw conveying shaft 711 to rotate, so that the conveying screw conveying shaft 711 conveys the sand inside the storage cylinder 707 into the middle box 706 through the screw blades. The sand falls into the porcelain bottle 607 through the feeding hole 205. The extension end of the vibrating hydraulic rod 701 continuously hits the vibrating component 601, causing the porcelain bottle 607 to vibrate. When the porcelain bottle 607 vibrates, the outer buffer ring 723 and the top buffer ring 206 block the force generated by the vibration of the porcelain bottle 607, so that the fine sand is compacted inside the porcelain bottle 607. Then, the output of the first winding motor 721 drives the first winding roller 720 to reset and rotate, so that the first winding roller 720 releases the soft pad 201. The output of the second winding motor 722 drives the second winding roller 725 to reset and rotate, so that the second winding roller 725 winds up the soft pad 201, thereby pulling the first sealing plate 202 to move into the middle box 706, so that the feeding plate 204 is located inside the second side box 704. During this process, the soft pad 201 drives the second rack 802 to move away from the first gear 806, so that the second rack 802 drives the first gear 806 to drive the first threaded rod 805 to reset and rotate, so that the first threaded rod 805 drives the first piston rod 803 to move upward, so that the gas inside the back pressure piston cylinder 807 enters the middle box 706 through the back pressure pipe 801, and enters the porcelain bottle 607 through the feeding hole 205, so that the inside of the porcelain bottle 607 returns to normal pressure. When the second rack 802 disengages from the first gear 806, the gas inside the back pressure piston cylinder 807 is exhausted. At this time, the feeding hole 205 is still connected to the inside of the porcelain bottle 607. When the feeding plate 204 moves into the second side box 704, the sand inside the feeding hole 205 falls into the inlet pipe 713 through the through hole, and enters the return material machine 714 through the inlet pipe 713. Then, the output end of the conveying motor 708 drives the conveying screw conveyor shaft 711 to rotate in the opposite direction. At this time, the conveying screw conveyor shaft 711 can drive the one-way bearing 717 to rotate the return screw conveyor shaft 715 through the two sprockets 718. This causes the return screw conveyor shaft 715 to drive the sand inside the return material machine 714 to fall into the storage cylinder 707 below the mounting base 710 through the outlet pipe 716, so that the sand is located above the first sealing plate 202. Then, the telescopic end of the lifting hydraulic rod 106 drives the mounting arm 107 to move upward, which causes the mounting arm 107 to drive the fine sand packing assembly 4 and the coarse sand packing assembly 5 to move upward, which causes the first rack 606 to drive the second gear 907 to drive the second threaded rod 902 to reset and rotate, which causes the second threaded rod 902 to drive the second piston rod 903 to move towards the discharge pipe 904, so that the gas inside the negative pressure piston cylinder 901 is discharged through the discharge pipe 904. When the first rack 606 and the second gear 907 disengage, the gas inside the negative pressure piston cylinder 901 is completely discharged. Coarse sand filling process: First, the output end of the rotary motor 104 drives the turntable 103 and the clamp 6 to rotate, so that the porcelain bottle 607 on the clamp 6 rotates to the bottom of the fine sand packing assembly 4. Then, the telescopic end of the lifting hydraulic rod 106 drives the mounting arm 107 to move down, so that the mounting arm 107 drives the fine sand packing assembly 4 and the coarse sand packing assembly 5 to move down. During the downward movement, the top of the porcelain insulator 607 is inserted into the bottom of the inlet tube 724; The weight of the sand trapped at the top of the second sealing plate 207 is detected by the pressure sensor inside the second sealing plate 207. The output of the first winding motor 721 drives the first winding roller 720 to rotate, so that the first winding roller 720 winds up the soft pad 201. The output of the second winding motor 722 drives the second winding roller 725 to rotate, so that the second winding roller 725 releases the soft pad 201, thereby pulling the second sealing plate 207 to move into the first side box 703, so that the feeding plate 204 is located inside the middle box 706. When the feeding plate 204 moves into the middle box 706, the sand trapped inside the middle box 706 enters the porcelain bottle 607 through the feeding hole 205. Then, the output end of the conveying motor 708 drives the conveying screw conveying shaft 711 to rotate, so that the conveying screw conveying shaft 711 conveys the sand inside the storage cylinder 707 into the middle box 706 through the screw blades. The sand falls into the porcelain bottle 607 through the feeding hole 205. The extension end of the vibrating hydraulic rod 701 continuously hits the vibrating component 601, causing the porcelain bottle 607 to vibrate. When the porcelain bottle 607 vibrates, the outer buffer ring 723 and the top buffer ring 206 block the force generated by the vibration of the porcelain bottle 607, so that the coarse sand is solid inside the porcelain bottle 607. Then, the output of the first take-up motor 721 drives the first take-up roller 720 to reset and rotate, so that the first take-up roller 720 releases the soft pad 201. The output of the second take-up motor 722 drives the second take-up roller 725 to reset and rotate, so that the second take-up roller 725 rewinds the soft pad 201, thereby pulling the second sealing plate 207 to move into the middle box 706, so that the feeding plate 204 is located inside the second side box 704. When the feeding plate 204 moves into the second side box 704, the sand inside the feeding hole 205 falls into the inlet pipe 713 through the through hole, and enters the return material machine 714 through the inlet pipe 713. Then, the output end of the conveying motor 708 drives the conveying screw conveyor shaft 711 to rotate in the opposite direction. At this time, the conveying screw conveyor shaft 711 can drive the one-way bearing 717 to rotate the return screw conveyor shaft 715 through the two sprockets 718. This causes the return screw conveyor shaft 715 to drive the sand inside the return material machine 714 to fall into the storage cylinder 707 below the mounting base 710 through the outlet pipe 716, so that the sand is located above the second sealing plate 207. Then, the telescopic end of the lifting hydraulic rod 106 drives the mounting arm 107 to move upward, so that the mounting arm 107 drives the fine sand filling assembly 4 and the coarse sand filling assembly 5 to move upward. When the turntable 103 drives the porcelain bottle 607 after filling to rotate to the unloading station, the telescopic end of the clamping cylinder 604 drives the clamping block 605 to reset and move, releasing the fixation of the porcelain bottle 607, and then the porcelain bottle 607 is removed from above the fixed seat 602.
