Description

Technical Field

[0001] This utility model relates to the technical field of transformer casting equipment, specifically to an automatic heating and feeding device and feeding system. Background Technology

[0002] The casting process for dry-type transformers requires resin, which must be heated after leaving the warehouse before it can be used for material feeding. Traditional factories typically use manual transfer to the curing oven, which is labor-intensive and physically demanding.

[0003] Currently, the industry generally uses forklifts or RGVs to transport resin out of the warehouse into a curing oven. After heating for a certain period of time, the resin is heated to the required temperature and then placed into the loading port of the casting tank for pouring.

[0004] However, existing technical solutions not only require multiple handling operations, but also the resin is heavy and the transfer speed is slow, requiring special transport vehicles such as forklifts and RGV railcars for transfer; in addition, since the transformer production process requires a curing process, factories generally use curing ovens to heat the resin, but considering the speed of use and cooling, usually not a large amount is heated at a time, but curing ovens are usually large and have high starting power, resulting in a large amount of energy waste in each heating process. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem of the cumbersome process of heating resin in a curing oven and multiple transfers. It provides an automatic heating and feeding system for transformer casting, which can be placed next to the casting equipment for convenient and timely material extraction via the feeding device, avoiding the complicated transfer process. The main concept is as follows:

[0006] An automatic heating and feeding device includes a heating device, an induction controller, and a material extraction device detachably connected to the heating device. The heating device includes a heating chamber and a heating assembly. A material container is placed inside the heating chamber. The heating assembly is used to heat the heating chamber. The induction controller is electrically connected to the heating assembly. The induction controller is used to control the start and stop of the heating assembly.

[0007] The heating box has a connection port with a removable heat-insulating plug, and the material container has a material extraction port.

[0008] The material extraction device includes an extraction pipe and a suction pump. One end of the extraction pipe is connected to the suction pump, and the extraction pipe enters the heating box through a pipe connection port. The other end of the extraction pipe is connected to the extraction port of the material container.

[0009] This solution incorporates a dedicated automatic heating and feeding device based on the transformer casting process. An induction controller manages the heating components' on / off state. The small size of the heating chamber allows the device to be installed directly next to the casting process, facilitating the extraction and feeding of heated materials. A material extraction port is installed on the cabinet door of the automated warehouse, sealed with an insulation plug. During use, the insulation plug is removed, and the extraction pipe is extended into the automated warehouse to complete the extraction, thus improving operational efficiency.

[0010] Preferably, the heating chamber further includes a heating station where two material containers are placed; and / or, the two material containers are respectively filled with resin and curing agent. By setting the heating station in a heating chamber to contain material containers of different materials, the heating chamber can achieve simultaneous heating of two materials in a single heating cycle. Furthermore, in this solution, the resin and curing agent in the material containers achieve the same standard heating temperature and time. Simultaneously, after heating, it facilitates efficient processing of both materials and allows for easy mixing and subsequent application in the casting process.

[0011] The second aspect of this invention aims to solve the technical problem of difficulty in connecting the extraction pipe and the material container. Furthermore, a feeding tray is provided between the heating station and the material container. The feeding tray has two positioning slots, which are used to position the material container, with the material inlet of the material container and the connection port of the heating box corresponding to each other. This solution positions the material container via the positioning slots, allowing the material inlet and connection port to be directly aligned when the feeding tray is placed inside the heating box. The extraction pipe extending into the heating box can then directly connect to the material inlet of the material container for extraction, simplifying the assembly steps and improving assembly efficiency.

[0012] Preferably, the heating chamber further includes an insulated chamber body and an insulated chamber door. A heating component, employing heating pipes, is installed inside the insulated chamber body. These heating pipes are evenly distributed along the inner wall of the insulated chamber body. The insulated chamber body and the insulated chamber door are slidably connected. The insulated chamber body and door ensure that the heating chamber maintains its temperature after the heating component has finished heating, thus maintaining the stable viscosity of the resin and curing agent, and consequently ensuring a stable extraction speed of the extraction device.

[0013] Preferably, the device further includes a lifting mechanism, which comprises a support frame and a lifting assembly. The support frame is installed at the heating chamber location, and the lifting assembly is used to lift the insulation chamber door of the heating chamber; and / or, the insulation chamber door is a lift-up door. The lifting mechanism is also adapted to the insulation chamber door moving along the vertical direction. The lifting force of the lifting assembly and the gravity of the insulation chamber door are balanced, enabling the automatic opening and closing of the insulation chamber door through the lifting assembly, thus improving operational efficiency.

[0014] Preferably, the lifting mechanism further includes a lifting sensor, which is communicatively connected to a sensor controller. The lifting sensor controls the lifting assembly to raise and lower. When a container of material to be heated is placed into the heating chamber, the lifting sensor detects an object entering the heating chamber and controls the lifting assembly to raise the door of the insulated chamber. After the container of material enters the insulated chamber, the lifting sensor controls the lifting assembly to lower the door of the insulated chamber to seal the heating chamber. The sensor controller then controls the heating assembly to complete the heating of the container of material inside the heating chamber.

[0015] The third aspect of this invention aims to solve the technical problem of difficulty in removing residual material from the bottom of the material container. Further, a support base is installed at the bottom of the heating box, and the support base is equipped with a lifting mechanism. The lifting mechanism is installed on the side away from the connection port of the heating box. The lifting mechanism includes an output rod and a power component. The power component controls the linear extension and retraction of the output rod, which provides an upward force to the heating box; and / or, the support base and the side of the heating box near the connection port are hinged together. This solution, by activating the lifting mechanism, raises the end of the heating box away from the connection port. After the heating box tilts, the material in the internal material container flows towards the suction port, reducing residual material in the material container.

[0016] Preferably, the support base further includes a mounting cavity, within which a suction pump is installed. The suction pump is used to simultaneously draw water from the two material containers at the heating station. The synchronously drawn materials, after being mixed with resin and curing agent, can then be added to the casting process.

[0017] Preferably, a feeding system includes two sets of automatic heating and feeding equipment. The simultaneous operation of both heating chambers ensures that heating and feeding occur concurrently. While the first set of automated storage and retrieval systems (AS / RS) is heating and feeding material, the second set begins heating. After the first set finishes feeding material and the second set finishes heating, the second set begins feeding material again. The first set of AS / RS then starts heating after replacing the material container, ensuring uninterrupted material flow during the casting process and improving production efficiency.

[0018] Preferably, it also includes a stacker crane, which is installed on one side of the insulated box door of the heating box and is used to transfer the loading pallet into and out of the insulated box.

[0019] The beneficial effects of this utility model are as follows:

[0020] A dedicated automatic heating and feeding device is set up according to the transformer casting process. The heating components are controlled by an induction controller to heat up and shut down. The heating box is small in size, which allows the device to be placed directly next to the casting process, facilitating the suction and feeding of heated materials. A material extraction port is set on the cabinet door of the automated warehouse. The material extraction port is sealed with a heat insulation plug. When in use, the heat insulation plug is removed and the material extraction pipe is extended into the automated warehouse to complete the material extraction, which improves the operating efficiency.

[0026] Example 1

[0027] like Figures 1-2 As shown, this embodiment provides an automatic heating and feeding device, including a heating device, an induction controller, and a feeding device detachably connected to the heating device. The heating device includes a heating box 1 and a heating component 2. A material container is placed inside the heating box 1. The heating component 2 is used to heat the heating box 1. The induction controller is electrically connected to the heating component 2. The induction controller is used to control the start and stop of the heating component 2.

[0028] The heating box 1 is provided with a connection port 13, and the connection port 13 is provided with a removable heat insulation plug. The material container is provided with a material extraction port.

[0029] The material extraction device includes a material extraction pipe and a suction pump 7. One end of the material extraction pipe is connected to the suction pump 7, and the material extraction pipe enters the heating box 1 through the pipe connection port 13. The other end of the material extraction pipe is connected to the extraction port of the material container.

[0030] This embodiment uses a dedicated automatic heating and feeding device based on the transformer casting process. The heating component 2 is controlled by an induction controller to heat up and shut down. The heating box 1 is small in size, allowing the device to be placed directly next to the casting process for easy extraction and feeding of heated materials. A material extraction port is set on the cabinet door of the automated warehouse, which is sealed with a heat insulation plug. When in use, the heat insulation plug is removed and the extraction pipe is extended into the automated warehouse to complete the extraction, thus improving operational efficiency.

[0031] like Figures 1-2 As shown, the heating box 1 in this embodiment also includes a heating station 14, on which two material containers are placed.

[0032] The two material containers are respectively filled with resin and curing agent, and the resin and curing agent are heated under the same conditions, both to 80 degrees Celsius.

[0033] The heating station 14 in a heating box 1 is equipped with material containers containing different materials, so that the heating box 1 can achieve simultaneous heating of two materials in one heating. In addition, the resin and curing agent filled in the material containers in this scheme meet the same heating temperature and time. At the same time, after heating, it can facilitate the processing efficiency of both materials and facilitate the extraction and mixing of both materials before putting them into the casting process.

[0034] like Figures 1-2 As shown, in this embodiment, a feeding tray 3 is provided between the heating station 14 and the material container. The feeding tray 3 has two positioning slots 31, which are positioned and installed with the material container. The material inlet of the material container and the connection port 13 of the heating box 1 are aligned. This design positions the material container through the positioning slots 31, allowing the material inlet and connection port 13 to be directly aligned when the feeding tray 3 is placed inside the heating box 1. The extraction pipe extending into the heating box 1 can then directly connect to the material inlet of the material container for extraction, simplifying the assembly steps and improving assembly efficiency.

[0035] The material container is transferred to the heating box 1 through the feeding tray 3 to realize the feeding of the heating process. The material in the heated material container is sucked out by the material extraction device to realize the feeding of the casting process.

[0036] The heating chamber 1 also includes an insulated chamber body 11 and an insulated chamber door 12. A heating assembly 2 is installed inside the insulated chamber body 11. The heating assembly 2 uses heating pipes 21, which are evenly distributed along the inner wall of the insulated chamber body 11. The insulated chamber body 11 and the insulated chamber door 12 are slidably connected. The insulated chamber body 11 and the insulated chamber door 12 ensure that the heating chamber 1 has a heat preservation function after the heating assembly 2 has finished heating, thus maintaining the stable viscosity of the resin and curing agent, and consequently ensuring the stable extraction speed of the extraction device.

[0037] Example 2

[0038] like Figures 1-2 As shown, this embodiment also includes a lifting mechanism 4, which includes a support frame 41 and a lifting assembly 42. The support frame 41 is installed at the heating box 1, and the lifting assembly 42 is used to lift the insulation box door 12 of the heating box 1. The insulation box door 12 is a lifting door. The lifting mechanism 4 is also adapted to the insulation box door 12 moving along the vertical direction. The lifting force of the lifting assembly 42 and the gravity of the insulation box door are balanced, so that the lifting assembly 42 can realize the automatic opening and closing of the insulation box door 12, improving the efficiency of operation.

[0039] The connection port 13 on one side of the heat preservation box 11 and the heat preservation box door 12 that is opened and closed by the lifting component 42 can be set as one, or they can be set separately on both sides of the heating box 1.

[0040] like Figure 1 As shown, the lifting assembly 42 in this embodiment uses an electric hoist, which is responsible for the power system of the lifting door. The lifting and resetting of the door is achieved by winding and unwinding the wire rope. In addition, this embodiment also provides a fall arrest mechanism, which is installed at the bottom of the support frame via a hook. The fall arrest mechanism is located next to the lifting assembly 42, and the safety rope is independent of the electric hoist's lifting power system. During normal operation, the safety rope of the fall arrest mechanism is in a slack state and does not bear the weight of the suspended load; the lifting assembly 42 is responsible for lifting. If the lifting assembly 42 fails, the door falls and pulls the safety rope, causing it to tighten instantly and bear the entire load. The safety rope of the fall arrest mechanism can immediately bear the weight of the suspended load, preventing it from falling.

[0041] The lifting mechanism 4 also includes a lifting sensor, which is connected in communication with the sensor controller. The lifting sensor is used to control the lifting assembly 42 to rise and fall.

[0042] When a material container to be heated is placed into the heating chamber 1, the lifting sensor detects an object that needs to enter the exterior of the heating chamber 1, and controls the lifting assembly 42 to lift the insulation chamber door 12. After the material container enters the insulation chamber, the lifting sensor controls the lifting assembly 42 to lower the insulation chamber door 12 to seal the heating chamber 1. The sensor controller then controls the heating assembly 2 to complete the heating of the material container inside the heating chamber 1.

[0043] The heating box 1 in this embodiment has a heat preservation function, with the door opening during feeding and closing during heating. Furthermore, the feeding tray 3 and the material container can be automatically positioned through laser alignment or QR code recognition, ensuring that the position of the material buckets placed on the tray is consistent with the preset position. The stacker crane achieves millimeter-level accuracy, feeding the tray containing the material buckets onto the heating station 14 of the heating box 1.

[0044] The material container has a one-way quick-connect port on its outer wall. This one-way quick-connect port can be coaxially aligned with the connection port of the insulation box door 12 of the heating box 1. This allows the insulation plug on the connection port 13 of the insulation box door 12 to be removed during material discharge. When the material discharge pipe extends into the heating box 1 through the connection port 13, it can be directly connected to the one-way quick-connect port of the material container. The material in the material container can then be directly drawn in by the suction pump 7.

[0045] Example 3

[0046] like Figures 1-2 As shown, in this embodiment, the bottom of the heating box 1 is equipped with a support base 5. The support base 5 is provided with a lifting mechanism 6. The lifting mechanism is installed on the side away from the connection port 13 of the heating box 1. The lifting mechanism 6 includes an output rod 62 and a power component 61. The power component 61 controls the linear extension and retraction of the output rod 62. The output rod 62 is used to provide an upward force for the heating box 1. The support base 5 and the side of the heating box 1 near the connection port 13 are hinged together.

[0047] By activating the lifting mechanism 6, the end of the heating box 1 away from the connection port 13 is lifted. After the heating box 1 is tilted, the material in the material container inside the heating box 1 flows towards the suction port, which can reduce the residual material in the material container.

[0048] The support base 5 also includes a mounting cavity 51, which contains a suction pump 7. The suction pump 7 is used to simultaneously suction the two material containers on the heating station 14. The synchronously suctioned materials, after being mixed with resin and curing agent, can be added to the casting process.

[0049] Example 4

[0050] A feeding system includes two sets of automatic heating and feeding devices. The simultaneous operation of both heating chambers 1 ensures that heating and feeding occur concurrently. While the first set of automated storage and retrieval systems (AS / RS) is heating and feeding material, the second set begins heating. After the first set finishes feeding material and the second set finishes heating, the second set begins feeding material again. The first set of AS / RS then starts heating after replacing the material container, ensuring uninterrupted material flow during the casting process and improving production efficiency.

[0051] This embodiment also includes a stacker crane, which is installed on one side of the insulated box door 12 of the heating box 1. The stacker crane is used to transfer the loading pallet 3 into and out of the insulated box 11. The stacker crane is linked to the insulated box door 12 of the heating box 1, so that the insulated box door 12 opens after the lifting sensor receives a material heating request from the stacker crane.

[0052] By utilizing the efficient movement of stacker cranes in automated warehouses, automated transfer can be achieved, reducing manual handling.

[0053] In this embodiment, the material container is a material barrel, which is custom-made by the manufacturer and pre-filled with the required resin or curing agent. During actual use, it is placed into the heating chamber directly for heating via the feeding system of this solution. The feeding equipment in this embodiment adopts an automated structure; a stacker crane combined with a feeding pallet places the material barrel into heating chamber 1 for heating. After heating, the material is output via a material extraction device.
