Abstract
Description
Technical Field
[0001] This invention relates to the field of insulator manufacturing technology, specifically to an automatic blank trimming machine and method for post-type insulators. Background Technology
[0002] An insulator is an electrical component used to support and insulate a live conductor. It is typically made by gluing or mechanically clamping together insulating parts (such as porcelain or rubber) and metal fittings (such as steel feet, iron caps, and flanges). Insulators are widely used in power systems, playing a crucial supporting and insulating role in various electrical equipment in transmission lines, power plants, and substations. The production process of porcelain insulators generally consists of five stages: clay preparation, molding, glazing, firing, assembly, and inspection. The molding stage includes four steps: vacuum clay refining, molding, trimming, and drying. Vacuum clay refining involves using a vacuum clay refining machine to remove air bubbles from the clay, forming solid clay sections. Lowering the air content of the clay reduces its water absorption rate and makes the internal structure more uniform. Molding involves pressing the clay into the shape of the insulator using a mold, followed by trimming to ensure the shape meets requirements. Some manufacturers combine these two processes, directly using a rotating blade to trim the blank, eliminating the need for pressing. However, this type of method has low production efficiency. A set of blades usually corresponds to only one blank, and manual assistance is often required for cutting and cleaning up debris, resulting in low automation. Summary of the Invention
[0003] To address the aforementioned problems, this invention proposes an automatic blank trimming machine for post-type insulators, comprising a trimming chamber, a feeding belt, a transition belt, and a discharge belt. The transition belt, via a clamping rod component in a clamping device, clamps the blank on the feeding belt and conveys it to the opening above the trimming chamber. A lifting device installed in the trimming chamber lowers the clamping rod component and the blank into the trimming chamber. The trimming device in the trimming chamber trims the blank. Subsequently, the lifting device resets the clamping rod component and the blank. The transition belt conveys the blank to the discharge belt for unloading. A recycling device is provided at the bottom of the trimming chamber.
[0004] Furthermore, the feed belt, transition belt, and discharge belt are plate conveyor belts composed of segmented plates. Material supports are installed on some segments of the feed belt and discharge belt, and mounting slots for connecting with clamping rod mechanisms are provided on some segments of the transition belt. The material supports and mounting slots are set at equal distances. The mounting slots below the beginning and end of the transition belt can correspond to the material supports above the end of the feed belt and the beginning of the discharge belt, respectively.
[0005] Furthermore, the feed belt and the discharge belt are respectively provided with slid grooves A and B perpendicular to the conveying direction, and slid grooves A and B are slidably connected to the material support.
[0006] Furthermore, the clamping rod component includes a base rod, with an electromagnetic connector in the middle for connecting the transition zone. Both ends of the base rod are slidably connected to sleeves above the inner end face of the clamping plate. The sleeves contain springs, with both ends of the springs abutting against the end faces of the clamping plate and the base rod, respectively. A rotating shaft is rotatably connected to the center of the lower part of the clamping plate. The end of the rotating shaft that is flush with the outer end face of the clamping plate has a connecting hole. When the clamping plate is located above the opening of the trimming chamber, the outer end face can fit against the lifting device.
[0007] Furthermore, the clamping device includes front and rear push plates located on both sides of the feed belt tail end and the discharge belt head end, and a stop plate is provided between the front and rear push plates. The stop plate has a slot A that can be slidably connected with the lifting device.
[0008] Furthermore, the lifting device includes a lifting platform, which is arranged on both side walls of the trimming chamber along the conveying direction of the transition zone. The vertical plate of the lifting platform is slidably connected to the slot B on the side wall. The outer end face of the vertical plate of one side of the lifting platform is connected to a horizontal plate. The top of the horizontal plate is slidably connected to a motor A via an electric rail. When the motor A moves to the position closest to the vertical plate, the output end of the motor A can pass through the shaft hole on the vertical plate.
[0009] Furthermore, the trimming device includes a rotating drum, with both ends of the rotating drum rotatably connected to the two side walls of the trimming chamber along the conveying direction of the transition zone. The rotating drum has a movement groove on its surface, and a threaded rod is rotatably connected between the two side walls of the movement groove. The threaded rod is threadedly connected to a slider, the bottom of the slider is in contact with the bottom of the movement groove, and the top of the slider is connected to a blade pusher. One end of the threaded rod is connected to the output end of motor B, motor B is fixed at one end of the rotating drum, and the other end of the rotating drum is engaged with the output end of motor C. Motor C is fixed on the outer side wall of the trimming chamber.
[0010] Furthermore, the recycling device includes a collection plate fixed to the inner side wall of the trimming chamber, which divides the trimming chamber into upper and lower parts. The top of the collection plate is a slope that descends from the outside to the inside to the crushing port. The crushing port connects the upper and lower parts of the trimming chamber. A hydraulic cylinder is installed on one side of the lower part of the trimming chamber, and the output end of the hydraulic cylinder is connected to a compression plate. An automatic door is installed on the side wall of the trimming chamber opposite to the compression plate.
[0011] The present invention also proposes a method for preparing post-type insulators, comprising the following steps:
[0012] Material handling stage: The feeding belt transports the billet to the bottom of the transition belt and corresponds to the clamping rod component. The push plates on both sides of the feeding belt push the clamping plate to clamp it. The rotating shaft is inserted into both ends of the billet. The transition belt transports the billet to the top of the blanking chamber and matches it with the lifting device. During this period, the anti-reverse plate and the vertical plate prevent the clamping plate from resetting, so that the clamping rod component remains in a clamped state.
[0013] Descent phase: Driven by the electric rail, the output end of motor A passes through the shaft hole and connects to the shaft hole. Then the electromagnetic connector disengages from the mounting slot, and the clamping rod component clamps the billet and descends with the lifting platform to the cutting position in the blank trimming chamber, matching the working height of the blank trimming device.
[0014] During the blank trimming stage: Motor A drives the blank to rotate via a rotating shaft, Motor C drives the rotating drum to rotate, and the blades in the blade pusher perform blank trimming operations. The blade pusher controls the cutting depth of the blades, and Motor B controls the horizontal position of the blades.
[0015] Recycling stage: During the blanking process, the scrap generated falls into the lower half of the blanking chamber along the slope at the top of the collecting plate. The hydraulic cylinder pushes the compression plate to compact the scrap into blocks. When the blocks reach the target size, the automatic door opens and the hydraulic cylinder pushes the blocks out of the blanking chamber for recycling.
[0016] Ascending stage: The clamping rod component clamps the finished blank and rises with the lifting platform to the original height. The electromagnetic connector connects with the mounting slot, and the output end of motor A disconnects from the connection with the coupling hole.
[0017] Unloading stage: The transition belt transports the billet to the top of the discharge belt and aligns it with the material support on the discharge belt. The push plates on both sides of the discharge belt retract to both sides, the clamping plates reset, the rotating shaft is pulled out of the billet, and the billet is transferred to the next process by the discharge belt.
[0018] The beneficial effects of this invention are as follows:
[0019] This invention uses a transition belt to pick up material from the feed belt, then transports the billet to the trimming chamber for trimming, and then uses another transition belt to transport the processed billet to the discharge belt for the next process. It features a high degree of automation and comes with a built-in scrap recycling device that can compress the scrap generated during the trimming process into blocks for reuse, eliminating the need for manual processing and cleaning. One trimming device can process two billets simultaneously and can precisely control the cutting depth and horizontal position of the blades to meet the processing needs of various types of post insulators.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0029] The present invention will be further described below with reference to the accompanying drawings:
[0030] like Figures 1 to 6As shown, an automatic blank trimming machine for post insulators includes a trimming chamber 1, a feeding belt 2, a transition belt 3, and a discharge belt 4. The feeding belt 2, transition belt 3, and discharge belt 4 are plate conveyor belts composed of sections of uniform specifications. Material holders 24 are installed on some sections of the feed belt 2 and the discharge belt 4 (every three sections are spaced apart). The material holders 24 are slidably connected to the feed belt 2 and the discharge belt 4 respectively through the slide grooves A201 and B401, so as to realize the position adjustment perpendicular to the transmission direction, thereby meeting the placement needs of different specifications of blanks 5. Some sections of the transition belt 3 (same as above, that is, the material holders 24 and the installation grooves 301 are set at equal distances) are provided with installation grooves 301. The installation grooves 301 below the beginning and end of the transition belt 3 can correspond to the material holders 24 above the end of the feed belt 2 and the beginning of the discharge belt 4 respectively (because they are set at equal distances, they can correspond). Since the installation grooves 301 can connect to the electromagnetic connectors 601 in the middle of the base rod 6 in the clamping rod component, the clamping rod component can match the position of the blanks 5 on the corresponding material holders 24.
[0031] In this embodiment, the two ends of the base rod 6 are slidably connected to the sleeve 701 above the inner end face of the clamping plate 7. The sleeve 701 contains a spring 8, and the two ends of the spring 8 abut against the end faces of the clamping plate 7 and the base rod 6, respectively. The lower center of the clamping plate 7 is rotatably connected to the rotating shaft 9. The end of the rotating shaft 9 that is flush with the outer end face of the clamping plate 7 has a connecting hole 901. The front push plates 10 located on both sides of the tail end of the feed belt 2 (driven by pistons, the cylinder of the pistons can be fixed in the wall) push the clamping plate 7 to compress the spring 8. The rotating shafts on both sides are thus inserted into the two ends of the blank 5 to achieve the clamping of the blank 5. The front and rear push plates 10 are provided on both sides of the first end of the discharge belt 4. The front and rear push plates 10 are provided with a stop plate 11. The stop plate 11 can continuously press against the clamping plate 7 when the transition belt 3 transports the blank 5, so that the clamping rod component is kept in a clamped state. When the processing is completed, when the transition belt 3 transports the blank 5 to the unloading point above the first end of the discharge belt 4, the rear push plates 10 retract to both sides, the clamping plate 7 is reset, and the blank 5 is disengaged from the rotating shaft 9 (the material support 24 on the discharge belt 4 can prevent the blank 5 from moving perpendicular to the transmission direction). The processed blank 5 falls onto the material support 24.
[0032] In this embodiment, the anti-reverse plate 11 has a slot A1101 in the middle, which corresponds to the slot B101 on the blank trimming chamber 1. The vertical plate 1201 in the lifting platform 12 is slidably connected to both of them through electric slide rails. One side of the lifting platform 12 has a vertical plate 1201 connected to a horizontal plate 1202 on its outer end face. The top of the horizontal plate 1202 is slidably connected to a motor A13 via an electric rail 1203. When the motor A13 moves to the position closest to the vertical plate 1201, the output end of the motor A13 can pass through the shaft hole 1204 on the vertical plate 1201. When the billet 5 is transported from the transition belt 3 to the opening above the blanking chamber 1, the outer end faces of the clamping plates 7 at both ends of the billet 5 are in contact with the vertical plates 1201 of the two lifting platforms 12 (the lifting platform 12 is at its highest point and located in the slot A1101). At this time, driven by the electric rail 1203, the output end of the motor A13 can extend into the connecting shaft hole 901 for transmission connection (e.g., Figure 6 As shown, through the spline structure, when the electromagnetic connector 601 is disconnected from the mounting groove 301, the lifting platform 12 can lower the clamping rod component and the blank 5 into the blank trimming chamber 1, corresponding to the height of the blank trimming device.
[0033] In this embodiment, as Figure 4 As shown, the trimming device includes a rotating drum 14. Both ends of the rotating drum 14 are rotatably connected to the two side walls of the trimming chamber 1 (along the conveying direction of the transition zone 3) via bearings. The rotating drum 14 has a movement groove 1401 on its surface. A threaded rod 15 is rotatably connected between the two side walls of the movement groove 1401. The threaded rod 15 is threadedly connected to a slider 16. The bottom of the slider 16 is in contact with the bottom of the movement groove 1401. A blade pusher 17 is connected to the top of the slider 16. The blade pusher 17 has a built-in electric slide rail that can control the cutting depth of the blade. One end of the threaded rod 15 is connected to the output end of a motor B18. The motor B18 is fixed to one end of the rotating drum 14. When the motor B18 drives... When the threaded rod 15 rotates, the slider 16 engages and moves on the threaded rod 15, thereby controlling the horizontal position of the blade (multiple sliders 16 can be equidistantly arranged on the threaded rod 15, and the blade pusher 17 connected to each slider 16 is only responsible for a portion of the blank trimming task, thereby improving processing efficiency). The other end of the rotating drum 14 meshes with the output end of the motor C19. The motor C19 is fixed on the outer wall of the blank trimming chamber 1. The motor C19 is used to drive the rotating drum 14 to rotate. Since both the rotating drum 14 and the blank 5 rotate under the drive of the motor (in traditional equipment, only the blade rotates), a set of blank trimming devices can process two blanks 5 simultaneously on both sides.
[0034] In this embodiment, the recycling device includes a collecting plate 20 fixed to the inner side wall of the trimming chamber 1. The collecting plate 20 divides the trimming chamber 1 into upper and lower parts. The top of the collecting plate 20 is a slope that descends from the outside to the inside to the crushing port 2001. The crushing port 2001 passes through the upper and lower parts of the trimming chamber 1. A hydraulic cylinder 21 is installed on one side of the lower half of the trimming chamber 1. The output end of the hydraulic cylinder 21 is connected to a compression plate 22. An automatic door 23 is installed on the side wall of the trimming chamber 1 opposite to the compression plate 22. The hydraulic cylinder 21 drives the compression plate 22 to compress the crushed material to a certain pressure and then contracts. Therefore, the larger the material block formed by compressing the crushed material, the shorter the stroke of the hydraulic cylinder 21. The size of the material block can be determined by the position sensor to determine the opening time of the automatic door 23.
[0035] This invention also proposes a method for transporting bulk materials in mines, comprising the following steps:
[0036] Material handling stage: The feeding belt 2 transports the billet 5 to the lower part of the transition belt 3 to correspond with the clamping rod component. The push plates 10 on both sides of the feeding belt 2 push the clamping plate 7 to clamp. The rotating shaft 9 is inserted into both ends of the billet 5. The transition belt 3 transports the billet 5 to the upper part of the blanking chamber 1 to match the lifting device. During this period, the anti-reverse plate 11 and the vertical plate 1201 prevent the clamping plate 7 from resetting, so that the clamping rod component remains in a clamped state.
[0037] Descent phase: Driven by the electric rail 1203, the output end of the motor A13 passes through the shaft hole 1204 and is driven to connect with the shaft hole 901. Then the electromagnetic connector 601 disengages from the mounting slot 301, and the clamping rod component clamps the billet 5 and descends with the lifting platform 12 to the cutting position in the blanking chamber 1, matching the working height of the blanking device.
[0038] During the trimming stage: Motor A13 drives the blank 5 to rotate via the rotating shaft 9, and motor C19 drives the rotating drum 14 to rotate. The blades in the blade pusher 17 perform trimming operations on the blanks 5 on both sides. The blade pusher 17 controls the cutting depth of the blades, and motor B18 controls the horizontal position of the blades.
[0039] Recycling stage: During the blanking process, the scrap generated falls along the slope at the top of the collecting plate 20 into the lower half of the blanking chamber 1. The hydraulic cylinder 21 pushes the compression plate 22 to compact the scrap into blocks. When the blocks reach the target size (generally determined by the position sensor sensing the farthest position of the compression plate 22), the automatic door 23 opens, and the hydraulic cylinder 21 pushes the blocks out of the blanking chamber 1 for recycling.
[0040] Ascending stage: The clamping rod component clamps the finished blank 5 and rises to the original height with the lifting platform 12. The electromagnetic connector 601 connects with the mounting groove 301, and the output end of the motor A13 disconnects from the connection with the coupling hole 901.
[0041] Unloading stage: The transition belt 3 transports the billet 5 to the top of the discharge belt 4 and corresponds to the material support 24 on the discharge belt 4. The push plates 10 on both sides of the discharge belt 4 retract to both sides, the clamping plate 7 resets, the rotating shaft 9 is pulled out from the billet 5, the billet 5 falls onto the material support 24, and is transferred to the next process by the discharge belt 4.
[0042] This invention can trim blanks for post insulators of various specifications. One set of trimming devices can trim two blanks at the same time, and has the function of recycling broken materials, and has a high degree of automation.
[0043] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
