Technical Field

[0001] The invention relates to the technical field of fire protection pipe processing, and in particular to a hot melt machine for producing fire protection interfaces with a positioning docking structure. Background Art

[0002] The fire interface is a connector used to connect fire hoses, fire hoses, fire hydrants and other fire fighting equipment. It plays a vital role in fire fighting. The corrosion resistance of the fire interface refers to the ability of the interface to resist corrosion when it comes into contact with corrosive media such as water and chemicals. The corrosion resistance of the fire interface must meet the requirements of national standards to ensure that there will be no corrosion or damage to the interface during fire fighting, which will affect the service life. The high temperature resistance of the fire interface refers to the ability of the interface to resist high temperature when it comes into contact with high temperature media. The high temperature resistance of the fire interface must meet the requirements of national standards to ensure that there will be no softening or deformation of the interface during fire fighting, which will affect the use effect.

[0003] When traditional welding machines cut and hot-melt fire-fighting interfaces, the fire-fighting interfaces need to be frequently replaced and connected before welding can be performed, which increases the labor intensity of the fire-fighting interface welding work. Summary of the invention

[0006] The docking component includes a fixed seat, a side surface of the bracket is fixedly connected to the first motor, the inner side of the bracket is rotatably connected to a screw rod, one end of the screw rod is fixedly connected to the output end of the first motor, a sliding rod is fixedly connected to the inner side of the bracket, the side surface of the screw rod is threadedly connected to the fixed seat, a rotating block is inserted at the top of the fixed seat, and a clamping plate is fixedly connected to the bottom of the rotating block, and the side surface of the rotating block is threadedly connected to the inner side of the fixed seat; the fire interface is placed on the fixed seat, and the fire interface to be processed is limited and fixed by rotating the rotating block and driving the clamping plate through the rotating block. At the same time, semi-cylindrical friction blocks are evenly arranged on the clamping plate, thereby increasing the friction between the friction block and the fire interface. At the same time, the friction block is made of rubber material, thereby avoiding excessive extrusion force between the friction block and the fire interface, which will cause friction damage to the fire interface. By turning on the first motor, the output end of the first motor drives the screw rod to rotate, so that the screw rod drives the fixed seat to move, thereby facilitating the movement of the docking position of the two fire interfaces.

[0007] Preferably, the hot melt component includes a fixed frame, a side surface of the fixed frame is slidably connected to the bracket, the side surface of the fixed frame is fixedly connected to a connecting frame, the side surface of the connecting frame is fixedly connected to a second motor, the output end of the second motor is fixedly connected to the connecting frame, the inner side of the fixed frame is slidably connected to a connecting plate, a side of the connecting plate away from the second motor is fixedly connected to a cutting mechanism, a side of the fixed frame away from the second motor is fixedly connected to a third motor, the output end of the third motor is fixedly connected to a moving plate, and a side of the moving plate away from the third motor is fixedly connected to a melting mechanism; when the positions of the two fire-fighting interfaces are appropriately adjusted, the fixed frame is pushed to move inside the bracket, and at the same time, the second motor is turned on, and the cutting mechanism is driven to move on the fixed frame through the connecting plate via the output end of the second motor, thereby The cutting mechanism is used to cut the end face of the fire protection interface to be welded, so that the welded end face is smoother and more convenient for welding. At the same time, after the cutting mechanism has cut the welded end face flat, the cutting mechanism is driven away for reset movement through the output of the second motor. At the same time, the position of the fixed frame is moved, the third motor is turned on, and the melting mechanism is driven by the output end of the third motor to perform hot-melting work on the end face to be welded. When the hot-melting work is completed, the melting mechanism is driven to reset movement through the output end of the third motor. At the same time, the first motor is turned on, and the screw rod is driven to rotate in the bracket through the output end of the first motor, so that the docking component drives the two fire protection interfaces to move relative to each other, thereby squeezing and fixing the hot-melted fire protection interface. When the docked fire protection interface is cooled, the docking component is opened to take out the fire protection interface.

[0008] Preferably, the cutting mechanism comprises a connecting block, the side surface of the connecting block is fixedly connected to the connecting plate, the middle part of the inner side of the connecting block is fixedly connected to a dual-axis motor, the output ends of the dual-axis motor are fixedly connected to a rotating shaft, one end of the rotating shaft away from the dual-axis motor is fixedly connected to a fixing plate, the inner side of the fixing plate is fixedly connected to a milling cutter, and the inner side of the fixing plate is fixedly connected to a grabbing component; when the second output end drives the connecting block to move toward the fire interface through the connecting plate, the dual-axis motor is turned on, and the fixed plate is driven to rotate through the output end of the dual-axis motor. Thereby, the milling cutter on the fixed plate performs cutting processing on the end face to be welded of the fire protection interface. When the milling cutter performs cutting processing on the fire protection interface, a large amount of long waste chips will be generated. When the fixed plate rotates, the waste chips generated during processing are easily entangled on the milling cutter. When the milling cutter continues to cut the welding end face, a large amount of long waste chips will be entangled on the milling cutter, thereby interfering with the normal cutting work of the milling cutter. By arranging a grabbing assembly on the inner side of the fixed plate, when the fixed plate rotates, the grabbing assembly can be used to grab the debris generated by the milling cutter cutting.

[0009] Preferably, the grabbing assembly comprises a rotating shaft, the side surface of the rotating shaft is fixedly connected to the inner side of the fixed plate, grabbing rods are fixedly connected to both sides of the rotating shaft, a rotating groove is provided on the side surface of the grabbing rod, a rotating rod is rotatably connected to the inner side of the rotating groove, a clearance groove is provided on both sides of the rotating rod, and a curved hook is fixedly connected to the side surface of the grabbing rod; when the fixed plate rotates, the rotating shaft is driven to rotate inside the fixed plate by the action of centrifugal force, so that the rotating shaft drives the grabbing rod to rotate, so that the rotating rod rotates in the rotating groove The grabbing rod is rotated inside, so that by opening a giveway groove on both sides of the rotating rod, the rotating rod can grab the long waste chips generated by the milling cutter during processing when the rotating rod rotates, thereby avoiding the long waste chips generated during processing to be entangled on the milling cutter, so that the waste chips interfere with the normal cutting work. At the same time, by evenly arranging curved hooks on the grabbing rod, when the grabbing rod rotates, the curved hooks can hook the chips when the milling cutter cuts the fire interface, thereby avoiding the phenomenon of chips splashing when processing the fire interface.

[0010] Preferably, the melting mechanism comprises a heating plate, a side surface of the heating plate is fixedly connected to a movable frame, the side surface of the movable frame is fixedly connected to the movable plate through a round rod, the inner side of the movable frame is slidably connected to the fixed frame, the top of the movable frame is slidably connected to an extrusion frame, the side surface of the movable frame is fixedly connected to a guide rod, the side surface of the guide rod is slidably connected to the inner side of the fixed frame, a connecting spring is sleeved on the guide rod, one end of the connecting spring is fixedly connected to the movable frame, the other end of the connecting spring is fixedly connected to the top of the fixed frame, and the bottom of the extrusion frame is fixedly connected to a contact assembly; when the cutting mechanism cuts and flattens the hot-melt end surface of the fire-fighting interface, The output end of the first motor drives the screw rod to move on the bracket, so that the cut end faces of the two fire protection interfaces are abutted against the heating plate, so that the heating plate performs hot-melt treatment on the end faces of the two fire protection interfaces. When the heating plate completes the hot-melt work, it is driven by the third motor to move and reset, and then the extrusion frame is pressed to drive the contact component to contact and move both sides of the heating plate, so that the contact component cleans the side of the heating plate, thereby avoiding that after the heating plate performs hot-melt work on the fire protection interface, since the fire protection interface is made of materials such as plastic or rubber, some tiny particles or molten materials may adhere to the heating plate during the heating process.

[0011] Preferably, the contact assembly includes a contact rod, both ends of which are fixedly connected to a contact plate, one side of the contact plate is fixedly connected to a scraper, and the side of the contact plate away from the scraper is rotatably connected to a roller; through the pressing frame, the extrusion frame moves downward on the fixed frame through the guide rod, so that the extrusion frame drives the scraper to clean the side of the heating plate through the contact plate, thereby avoiding that after the heating plate hot-melts the fire-fighting interface, the side of the heating plate will remain molten material and adhere to the heating plate, and at the same time, after the scraper cleans the side of the heating plate, the roller can be used to clean and wipe the area cleaned by the scraper. After cleaning the heating plate, the extrusion frame is driven to move upward and reset through the stretching reset of the connecting spring through the extrusion force of the contact on the extrusion frame.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The present invention places the fire interface on a fixed seat by setting a docking component, and the fire interface to be processed is limited and fixed by rotating the rotating block and driving the clamping plate through the rotating block. At the same time, semi-cylindrical friction blocks are evenly arranged on the clamping plate to increase the friction between the friction block and the fire interface. At the same time, the friction block is made of rubber material to avoid excessive extrusion pressure between the friction block and the fire interface, which will cause friction damage to the fire interface. By turning on the first motor, the output end of the first motor drives the screw rod to rotate, so that the screw rod drives the fixed seat to move, thereby facilitating the movement of the docking position of the two fire interfaces.

[0014] 2. The present invention sets a contact component, through a pressing frame, the extrusion frame moves downward on the fixed frame through a guide rod, so that the extrusion frame drives the scraper to clean the side of the heating plate through the contact plate, thereby avoiding that after the heating plate hot-melts the fire interface, the molten material will remain on the side of the heating plate and adhere to the heating plate. At the same time, after the scraper cleans the side of the heating plate, the roller can be used to clean and wipe the area cleaned by the scraper. After cleaning the heating plate, the extrusion frame is driven by the contact to exert an extrusion force on the extrusion frame, and the extrusion frame is driven to move upward and reset through the stretching and reset of the connecting spring.

[0015] 3. The present invention sets a cutting mechanism. When the second output end drives the connecting block to move toward the fire interface through the connecting plate, the dual-axis motor is turned on and the fixed plate is driven to rotate through the output end of the dual-axis motor, so that the milling cutter on the fixed plate cuts the end face to be welded of the fire interface. When the milling cutter cuts the fire interface, a large amount of long waste chips will be generated. When the fixed plate rotates, the waste chips generated during the processing are easily entangled on the milling cutter. When the milling cutter continuously cuts the welding end face, a large amount of long waste chips will be entangled on the milling cutter, thereby interfering with the normal cutting work of the milling cutter. By arranging a grabbing assembly on the inner side of the fixed plate, when the fixed plate rotates, the grabbing assembly can grab the debris generated by the milling cutter cutting.

[0016] 4. The present invention provides a grabbing assembly. When the fixed plate rotates, the centrifugal force drives the rotating shaft to rotate inside the fixed plate, so that the rotating shaft drives the grabbing rod to rotate, and the rotating rod rotates inside the rotating groove. Therefore, by providing a clearance groove on both sides of the rotating rod, the rotating rod can grab the long waste chips generated during the milling cutter processing when the rotating rod rotates, thereby avoiding the long waste chips generated during the processing to be entangled on the milling cutter, so that the waste chips interfere with the normal cutting work. At the same time, by evenly arranging curved hooks on the grabbing rod, when the grabbing rod rotates, the curved hooks can hook the chips when the milling cutter cuts the fire interface, thereby avoiding the phenomenon of chips splashing when the fire interface is processed.

[0038] The specific workflow is as follows:

[0039] During operation, the fire-fighting interface to be processed is placed on the docking component 2 for position fixing, and then the hot-melt component 3 is used to perform hot-melt work on the side of the two fire-fighting interfaces to be docked;

[0040] The fire interface is placed on the fixed seat 23, and the rotating block 25 is rotated to drive the clamping plate 26 through the rotating block 25 to limit and fix the fire interface to be processed.

At the same time, after the cutting mechanism 35 cuts the welded end surface smooth, the output of the second motor 33 drives the cutting mechanism 35 away for reset movement, and at the same time, the fixing frame 31 is moved Position, by turning on the third motor 36, the output end of the third motor 36 drives the melting mechanism 38 to perform hot-melting work on the end surface to be welded, and when the hot-melting work is completed, the output end of the third motor 36 drives the melting mechanism 38 to reset and move, and at the same time, by turning on the first motor 21, the output end of the first motor 21 drives the screw rod 24 to rotate in the bracket 1, so that the docking component 2 drives the two fire interfaces to move relatively, so as to squeeze and fix the hot-melted fire interfaces, and when the docked fire interfaces are cooled, the docking component 2 is opened to take out the fire interfaces;

[0042] After the second output end drives the connecting block 351 to move toward the fire interface through the connecting plate 34, the dual-axis motor 352 is turned on, and the fixed plate 354 is driven to rotate through the output end of the dual-axis motor 352, so that the milling cutter 355 on the fixed plate 354 cuts the end face of the fire interface to be welded.

When the fixed plate 354 rotates, the waste chips generated during the processing are easily entangled on the milling cutter 355. When the milling cutter 355 continuously cuts the welded end face, a large amount of long waste chips will be entangled on the milling cutter 355, thereby interfering with the normal cutting work of the milling cutter 355. By providing a grabbing component 356 on the inner side of the fixed plate 354, when the fixed plate 354 rotates, the debris generated when the milling cutter 355 is cut can be grabbed by the grabbing component 356.

[0043] When the fixed plate 354 rotates, the centrifugal force drives the rotating shaft 3561 to rotate inside the fixed plate 354, so that the rotating shaft 3561 drives the grabbing rod 3562 to rotate, so that the rotating rod 3564 rotates inside the rotating groove 3563, so that by providing the yield grooves 3565 on both sides of the rotating rod 3564, the rotating rod 3564 can grab the long waste chips generated during the processing of the milling cutter 355 when the rotating rod 3564 rotates, so as to avoid the long waste chips generated during the processing being entangled on the milling cutter 355, so that the waste chips interfere with the normal cutting work, and at the same time, by evenly providing the curved hooks 3566 on the grabbing rod 3562, when the grabbing rod 3562 rotates, the curved hooks 3566 can hook the chips when the milling cutter 355 cuts the fire interface, so as to avoid the phenomenon of chips splashing when the fire interface is processed;

[0044] After the cutting mechanism 35 cuts and levels the hot-melt end faces of the fire-fighting interface, the output end of the first motor 21 drives the screw rod 24 to move on the bracket 1, so that the cut end faces of the two fire-fighting interfaces are abutted against the heating plate 381, so that the heating plate 381 performs hot-melt treatment on the end faces of the two fire-fighting interfaces. When the heating plate 381 completes the hot-melt work, it is driven by the third motor 36 to move and reset, and the extrusion frame 383 is pressed to drive the contact assembly 386 to contact and move the two sides of the heating plate 381, so that the contact assembly 386 cleans the side of the heating plate 381, so as to avoid that after the heating plate 381 performs hot-melt work on the fire-fighting interface, since the fire-fighting interface is made of materials such as plastic or rubber, some tiny particles or molten materials may adhere to the heating plate 381 during the heating process;

[0045] Through the pressing frame, the extrusion frame 383 moves downward on the fixed frame 31 through the guide rod 384, so that the extrusion frame 383 drives the scraper 3863 to clean the side of the heating plate 381 through the contact plate 3862, thereby avoiding that after the heating plate 381 performs hot melting on the fire interface, there will be residual molten material adhering to the heating plate 381. At the same time, after the scraper 3863 cleans the side of the heating plate 381, the roller 3864 can be used to clean and wipe the area cleaned by the scraper 3863. After cleaning the heating plate 381, through the contact of the extrusion force on the extrusion frame 383, the extrusion frame 383 is driven to move upward and reset through the stretching reset of the connecting spring 385.
