Description
Technical Field
[0001] The invention relates to the technical field of fire extinguisher press-fitting equipment, in particular to automatic press-fitting equipment for processing a bottom ring of a fire extinguisher and a use method thereof. Background Art
[0002] Fire extinguishers are a common firefighting equipment, stored in public places or places where fires may occur. There are many types of fire extinguishers, which can be divided into dry powder fire extinguishers, foam fire extinguishers and carbon dioxide fire extinguishers. Among them, carbon dioxide fire extinguishers are mainly used to put out the initial fire of valuable equipment, archives, instruments and meters, electrical equipment below 600 volts and oils.
[0003] Carbon dioxide fire extinguishers can be divided into portable and trolley types according to their mobility. Trolley-type carbon dioxide fire extinguishers are larger in size than portable dry powder fire extinguishers, and the bottle body is installed on a frame for easy movement. Portable carbon dioxide fire extinguishers are placed in suitable locations. In order to ensure that the portable carbon dioxide fire extinguisher is placed stably, when manufacturing portable carbon dioxide fire extinguishers, it is necessary to use a pressing device to press a trumpet-shaped bottom ring on the bottom of the bottle body.
[0004] When using a press-fitting device to press-fit the fire extinguisher bottle body and the bottom ring, in order to avoid shaking during press-fitting, a clamp is required to limit and fix the fire extinguisher bottle body during press-fitting. It takes a long time to clamp and loosen the fire extinguisher bottle body, resulting in low efficiency in pressing the bottom ring of the fire extinguisher. Conventional means can use a limiter to quickly limit the bottle body. For example, an automatic press-fitting device for the bottom ring of a fire extinguisher with application number CN202111132298.8 quickly limits and fixes the bottle body through a bottle body limiting mechanism. There is no need to use a clamp to limit and fix the fire extinguisher bottle body, which effectively improves the press-fitting efficiency of the bottom ring of the fire extinguisher. However, when the existing equipment is press-fitting the bottom ring of the fire extinguisher, it is necessary to manually place the bottom ring and the fire extinguisher bottle body in the corresponding press-fitting station one by one, and then manually take out the pressed fire extinguisher bottle body after the press-fitting is completed. The fire extinguisher bottle has a certain height, and it takes a certain amount of time to place it in the bottle limiting mechanism and to take it out of the bottle limiting mechanism, which extends the bottom ring pressing cycle of a single fire extinguisher, and the bottom ring pressing efficiency needs to be further improved.
[0005] Therefore, an automatic press-fitting device for processing a bottom ring of a fire extinguisher and a method for using the same are proposed. Summary of the invention
[0006] The purpose of the present invention is to provide an automatic pressing device for processing the bottom ring of a fire extinguisher and a method for using the same, which solves the problem that the pressing efficiency of the bottom ring needs to be further improved due to manual placement of the fire extinguisher bottle body and the bottom ring during the pressing of the bottom ring of the fire extinguisher. By quickly positioning the fire extinguisher bottle body during its rolling process, the fire extinguisher bottle body rolls down by itself after the automatic pressing is completed, thereby realizing the continuous pressing production of the bottom ring of the fire extinguisher, and greatly improving the pressing efficiency of the bottom ring of the fire extinguisher.
[0007] To achieve the above object, the present invention provides the following technical solutions:
[0008] An automatic pressing device for processing the bottom ring of a fire extinguisher comprises a bottle body conveying platform, a bottom ring conveying platform, a pushing component, a pushing component, a top frame, a pressure component, a bottle end limit component, a flat plate, a positioning component and a first baffle, wherein the end of the bottle body conveying platform is fitted with the side wall of the bottom ring conveying platform, and both sides of the bottom ring conveying platform are configured with notches in the same straight line direction as the fitting part of the bottle body conveying platform, and the fire extinguisher bottle rolls from the bottle body conveying platform to the bottom ring conveying platform and rolls off the bottom ring conveying platform through the notches, the pushing component is installed on the surface of the bottom ring conveying platform, the inner wall of the bottom ring conveying platform is configured with a rectangular through groove, the pushing component is installed in the rectangular through groove, the top frame is installed on the top of the bottom ring conveying platform, and the pressure component is installed on the The top frame surface, and the bottom of the pressure assembly extends to the bottom of the top frame, the bottle end limit assembly is installed on the side of the bottom ring conveyor platform away from the pushing assembly, the flat plate is installed on the surface of the bottom ring conveyor platform, and the positioning assembly is installed between the flat plate surface and the surface of the bottom ring conveyor platform, the first baffle is installed on the flat plate surface, and the first baffle is vertically distributed in a natural state, and the first baffle is rotated from a vertical state to an inclined state when the first baffle is pushed laterally by the fire extinguisher bottle body. During the rotation of the first baffle, the positioning assembly flips up and resists the subsequent fire extinguisher bottle body. When the first baffle is tilted to a specific angle, the bottle end limit assembly drives the fire extinguisher bottle body to rotate to press the first baffle to a horizontal state and roll off the flat plate surface. After the first baffle loses the squeezing of the fire extinguisher bottle body, it recovers from a horizontal state to a vertical state.
[0009] When the bottom ring of a fire extinguisher is pressed, in order to avoid the need to accurately place the fire extinguisher bottle on the pressing station, which will have an adverse effect on the pressing efficiency of the bottom ring of the fire extinguisher, the existing technology often limits the position of the fire extinguisher bottle through a limiter. However, limiting the position of the fire extinguisher bottle from all sides by the limiter not only affects the automatic movement of the fire extinguisher bottle to the pressing station, but also affects the removal of the fire extinguisher bottle after the pressing is completed, resulting in the fire extinguisher bottle being unable to achieve automatic movement, resulting in the fire extinguisher bottom ring pressing efficiency being limited and difficult to improve.
[0010] The fire extinguisher bottle moves to the flat plate surface and is precisely positioned on the pressing station in a stationary state. At this time, the contact part between the flat plate and the fire extinguisher bottle is pre-treated to be magnetic, which can assist in positioning the fire extinguisher bottle and improve the positioning accuracy of the bottom ring of the fire extinguisher bottle during press-fitting.
[0011] After a fire extinguisher bottle rolls onto the surface of the flat plate, the change in the angle of the first baffle bar drives the change in the internal angle of the positioning component. At this time, the positioning component can not only connect the power of the pushing component, the pressure component and the bottle end limit component in sequence, but also limit the fire extinguisher bottle on the flat plate and intercept the fire extinguisher bottle on the bottle conveyor to achieve relative balance, keep the fire extinguisher bottle on the flat plate stationary on the pressing station, and ensure the pressing accuracy of the fire extinguisher bottom ring by ensuring the positioning accuracy.
[0012] Preferably, the positioning assembly includes a fixed column, a first transmission rod, a second transmission rod, a bottom bar, a third transmission rod, a second baffle, a fixed bar and a pressure switch, the two fixed columns are both mounted on the inner wall of the bottom ring conveyor platform, the first transmission rod is limitedly slid between the outer periphery of the fixed column, a compression spring is abutted between the upper fixed column and the inner wall of the first transmission rod, the fixed bar is mounted on the bottom of the bottom ring conveyor platform, the second transmission rod and the third transmission rod are both hinged on the side wall of the fixed bar, the end of the second transmission rod is fitted with the end of the first transmission rod, a bottom bar whose bottom is fitted with the third transmission rod is mounted at the bottom of the second transmission rod, the second baffle is rotatably mounted on the surface of the bottom ring conveyor platform, and the end of the third transmission rod is fitted with the bottom of the second baffle, the pressure switch is mounted on the side of the fixed bar away from the bottom bar, the first baffle rotates to change the angle of the second transmission rod, the second transmission rod rotates to change the angle of the third transmission rod, the third transmission rod applies pressure to the pressure switch to switch the state of the pressure switch.
[0013] In this technical solution, a positioning component is used to limit the movement trajectory of the fire extinguisher bottle. When a fire extinguisher bottle moves to the press-fitting station, the second stop bar can be flipped up to intercept the fire extinguisher bottle that continues to fall, so as to prevent the subsequent fire extinguisher bottle from causing adverse interference to the fire extinguisher bottle being press-fitted, thereby ensuring the press-fitting accuracy of the fire extinguisher bottle; in addition, when the fire extinguisher bottle moves to the press-fitting station and is blocked by the first stop bar, it is accurately positioned on the press-fitting station, and the first stop bar is pushed by the fire extinguisher bottle to change the angle When the change occurs, the pushing assembly, the pressure assembly and the bottle end limit assembly can be started accordingly to perform the automatic pressing operation; when the first baffle rotates, the second baffle can be driven to rotate through the first transmission rod, the second transmission rod, the bottom bar, the third transmission rod and the fixed bar, and the second baffle is flipped from a horizontal state to a 45° acute angle with the horizontal plane, thereby intercepting the fire extinguisher bottle that continues to fall, and at the same time, the first baffle can be stabilized with the help of the falling fire extinguisher bottle, to prevent the first baffle from continuously rotating and causing the fire extinguisher bottle to be unable to be accurately positioned on the pressing station.
[0014] In the prior art, the method of single supplementary bottom ring is used to press and install the bottom ring of the fire extinguisher, which requires manual operation, resulting in a low degree of automation in the press-installation operation and limiting the press-installation efficiency of the bottom ring of the fire extinguisher. In order to avoid the need for a single supplementary bottom ring, the present technical solution adopts a single delivery of a large number of bottom rings, and after the press-installation is completed, a large number of bottom rings are replenished again, thereby effectively reducing the adverse effects of the high frequency of bottom ring delivery on the press-installation efficiency of the fire extinguisher bottom ring.
[0015] Preferably, the pushing assembly includes a loading motor, a reciprocating translation block, a vertical bar, a receiving groove, a telescopic rod and an arc bar. The loading motor is installed on the side wall of the bottom ring conveyor platform, the reciprocating translation block is slidably set in a rectangular through groove, and the side wall of the reciprocating translation block is configured with an inclined groove, a turntable is sleeved on the end of the output shaft of the loading motor, and a plug column extending into the inclined groove is rotatably installed on the side wall of the turntable, the vertical bar is installed on the end of the reciprocating translation block, the receiving groove is configured on the side wall of the vertical bar, the telescopic rod is symmetrically installed in the receiving groove, and the arc bar is installed between the ends of the telescopic rod.
[0016] When the feeding motor rotates 180°, the reciprocating translation block can complete a single stroke. When the feeding motor continues to rotate 180°, the reciprocating translation block moves a single stroke in the opposite direction. Therefore, the feeding motor can realize the continuous pushing operation of the bottom circle during the unidirectional cycle rotation. There is no need to install an inverter or frequency converter in the equipment to change the rotation direction of the feeding motor, thereby reducing the manufacturing cost of the equipment and helping to improve the market competitiveness of the equipment.
[0017] Preferably, the pressure-applying assembly includes a hydraulic cylinder, a connecting plate, a limiting cylinder, a round rod, an electric lifting rod, a vertical rod, a bottom ring pushing strip, a straight slide groove and a straight through groove, the straight slide groove and the straight through groove are both constructed on the top of the top frame, the vertical rod slides through the straight through groove, the side wall of the vertical rod is slidably connected to the limiting slider, the end of the round rod is fixedly connected to the limiting slider, the bottom ring pushing strip is installed at the bottom of the vertical rod, the round rod slides through the limiting cylinder, the hydraulic cylinder is installed on the surface of the top frame, the connecting plate is installed between the end of the round rod and the end of the hydraulic cylinder piston rod, the electric lifting rod is installed on the surface of the vertical rod, and the bottom of the electric lifting rod extends into the straight slide groove.
[0018] When the bottom ring is pushed horizontally so that it is pressed onto the fire extinguisher bottle body, when the hydraulic cylinder extends horizontally, the piston rod drives the vertical rod and the bottom ring push bar to move horizontally through the connecting plate and the round rod. With the cooperation of the limit cylinder and the round rod, the stability of the round rod during movement can be improved. In addition, the height of the bottom ring push bar is changed by the electric lifting rod, so that when the bottom ring push bar is fitted or separated from the bottom ring, the end of the round rod contacts the vertical rod through the limit slider, which can adapt to the height change of the vertical rod, thereby ensuring that the movement of components does not interfere with each other.
[0019] After the bottom ring is pressed, the fire extinguisher bottle needs to be rolled off the flat plate. In the prior art, the fire extinguisher bottle is manually removed, which causes the efficiency of the fire extinguisher bottom ring press-fitting to be greatly affected by human factors. In order to avoid the need to manually remove the pressed fire extinguisher bottle, in this technical solution, the pressed fire extinguisher bottle is controlled to rotate to break through the first stop bar and then roll off the flat plate, thereby automatically removing the fire extinguisher bottle from the flat plate, thereby greatly improving the efficiency and automation of the fire extinguisher bottom ring press-fitting.
[0020] Preferably, the bottle end limit assembly includes a horizontal push rod, a mounting frame, a limit frame, a rotating motor, an end plate and a wedge-shaped rubber ring, the horizontal push rod is installed between the inner walls of the mounting frame, the mounting frame is installed on the side wall of the bottom ring conveyor platform, the limit frame is installed on the end of the horizontal push rod, the rotating motor is installed on the inner wall of the limit frame, the end plate is connected to the output shaft of the rotating motor, and the wedge-shaped rubber ring is sleeved on the outer periphery of the end plate.
[0021] When the bottom ring is pressed, the end of the fire extinguisher bottle body abuts against the inner wall of the bottom ring conveyor platform. After the pressing is completed, the horizontal push rod extends to drive the disc and the wedge-shaped rubber ring to move, so that the wedge-shaped rubber ring fits with the end of the fire extinguisher bottle body. Then, when the rotating motor is started, it can drive the fire extinguisher bottle body to rotate. Under the action of rotational inertia, the horizontal push rod contracts, and the fire extinguisher bottle body can break through the first baffle and fall from the flat surface. After the fire extinguisher bottle body loses its function, the first baffle returns to a vertical state and the second baffle returns to a horizontal state, so that the next fire extinguisher bottle body can move to the flat surface, so that the loading operation of the fire extinguisher bottle body can be carried out automatically and intermittently, which helps to improve the degree of automation of the pressing of the bottom ring of the fire extinguisher.
[0022] Preferably, the pushing assembly comprises a compression rod and a push plate, the compression rod is mounted on the surface of the bottom ring conveying platform, and the push plate is slidably mounted between the outer periphery of the compression rod and the surface of the bottom ring conveying platform.
[0023] The compression rod has a retractable structure inside, and under the action of the compression rod, the push plate can be driven to move toward the side of the fire extinguisher bottle body, thereby allowing the bottom ring to be replenished to the side of the fire extinguisher bottle body by itself. When the pushing component is started and completes a reciprocating stroke, the bottom ring can continue to be replenished to the side of the fire extinguisher bottle body.
[0024] Preferably, the side walls of the end plate are symmetrically provided with connecting strips, the ends of the connecting strips are fixed with limiting strips, and the side walls of the limiting frame are constructed with arc grooves adapted to the limiting strips.
[0025] Under the action of the connecting bar and the limit bar, when the rotating motor drives the end disc to rotate, the stability of the end disc rotation can be effectively improved, and the end disc can be prevented from moving horizontally and separating from the output shaft of the rotating motor, thereby ensuring the stability of the end disc during rotation.
[0026] Preferably, the hinged position between the third conduction rod and the fixed bar is located on a side of the third conduction rod close to the bottom bar, and the contact portion between the third conduction rod and the second baffle bar is arranged close to a rotating end of the second baffle bar.
[0027] Since the rotation angle of the first baffle is limited, in order to drive the second baffle to rotate at a large angle to intercept the fire extinguisher bottle at the rear, the above purpose can be achieved by designing the length of the second transmission rod and the third transmission rod.
[0028] Preferably, the bottom cross-section of the vertical rod is H-shaped, and a reinforcement block is installed between the side wall of the vertical rod and the surface of the bottom ring push strip.
[0029] The H-shaped design at the bottom of the vertical rod and the installed reinforcement block can effectively improve the structural strength of the pressure component, making it less likely for the bottom ring push bar to deform when moving.
[0030] A method for using an automatic press-fitting device for processing a bottom ring of a fire extinguisher comprises the following steps:
[0031] S1. The fire extinguisher bottle body, which has been pre-welded with the lower head but not the upper head, flows to the surface of the bottle body conveyor through the welding production line, and rolls along the inclined bottle body conveyor surface to the surface of the bottom ring conveyor;
[0032] S2. When a single fire extinguisher bottle rolls to the surface of the flat plate, the fire extinguisher bottle pushes the first stopper sideways, and the first stopper deflects a certain angle toward the forward side of the fire extinguisher bottle. During the first stopper process, the first conduction rod is continuously pressed downward, and the first conduction rod moves through the fixed column limit, and the bottom of the first conduction rod presses the bottom of the second conduction rod downward, and the second conduction rod pushes the third conduction rod downward through the bottom bar, and the third conduction rod moves upward near one end of the second stopper, flipping the second stopper upward, and the rear end of the second stopper pushes against the fire extinguisher bottle that has moved to the flat plate from below, and prevents the fire extinguisher bottle on the bottle conveying platform from continuing to roll toward the flat plate side;
[0033] S3, when the second gear bar turns up, the pressure switch is squeezed, the pressure switch turns on the power of the control panel, and the control panel turns on the power of the feeding motor, hydraulic cylinder, electric lifting rod, horizontal push rod and rotating motor in sequence through the delay device;
[0034] The output shaft of the feeding motor drives the plug to make circular motion in the chute through the turntable. When the plug moves to the horizontal position at both ends of the chute, the moving direction of the reciprocating translation block is switched. When the feeding motor rotates 180°, the reciprocating translation block completes a single stroke. When the power of the feeding motor is just turned on, the reciprocating translation block moves to the side of the bottle end limit assembly. The reciprocating translation block pushes the bottom circle in the same direction through the arc bar. After the power of the feeding motor is turned on, it rotates one circle and then the power is disconnected. When it rotates 180° later, the reciprocating translation block drives the arc bar to reset.
[0035] After the electric lifting rod is powered on, it contracts, lowers the bottom ring push bar, and the bottom ring fits into the arc groove of the bottom ring push bar. The hydraulic cylinder extends and pushes the bottom ring to move toward the side of the fire extinguisher bottle through the connecting plate and the round rod, pressing the bottom ring onto the fire extinguisher bottle. Then the electric lifting rod and the hydraulic cylinder are reset and the power is disconnected.
[0036] The horizontal push rod pushes the end plate and the wedge-shaped rubber ring to fit with the end of the fire extinguisher bottle body, and the rotary motor drives the end plate to rotate. The end plate drives the fire extinguisher bottle body to rotate through the wedge-shaped rubber ring, and then the horizontal push rod contracts. The fire extinguisher bottle body rotating at a certain speed pushes the first baffle bar, and the first baffle bar changes from tilted to horizontal. At this time, the rotating fire extinguisher bottle body falls from the edge gap of the bottom ring conveyor platform. After the fire extinguisher bottle body falls, the first baffle bar returns to a vertical state, and the second baffle bar returns to a horizontal state after losing the effect of the third transmission rod;
[0037] S4. After the next fire extinguisher bottle is moved onto the flat plate, the above steps S1-S3 are repeated to achieve the automatic press-fitting operation of the bottom ring of the fire extinguisher.
[0038] Compared with the prior art, the present invention has the following beneficial effects:
[0039] 1. The present invention provides a positioning component and a pressure component, and when performing the press-fitting operation of the bottom ring of the fire extinguisher, the fire extinguisher bottle body can be accurately positioned during the self-rolling process of the fire extinguisher bottle body, and the corresponding components can be started accordingly to complete the bottom ring replenishment and the bottom ring press-fitting operation, without the need to manually replenish the fire extinguisher bottle body individually. This not only greatly improves the degree of automation of the press-fitting operation of the bottom ring of the fire extinguisher, but also realizes continuous press-fitting operation, effectively improving the press-fitting efficiency of the bottom ring of the fire extinguisher.
[0040] 2. The present invention provides a positioning assembly and a bottle end limit assembly, so that the fire extinguisher bottle body remains stationary after it moves to the corresponding pressing station. After the bottom ring pressing operation is completed, the bottle end limit assembly is started to drive the fire extinguisher bottle body to rotate, so that the fire extinguisher bottle body falls from the side gap of the bottom ring conveying platform, and the fire extinguisher bottle body pressing station is vacated. This can ensure the continuous rolling replenishment of the fire extinguisher bottle body and improve the degree of automation of the bottom ring pressing operation, and can also control the pressing frequency, effectively ensuring the efficiency of the fire extinguisher bottom ring pressing.
[0041] 3. The present invention provides a pushing assembly and a pushing assembly, which can replenish the bottom ring to one side of the fire extinguisher bottle body according to the position change of the fire extinguisher bottle body during the pressing operation, thereby ensuring the supply of the bottom ring within a certain pressing operation cycle, so that the pressing operation of the fire extinguisher bottom ring can be automatically and continuously carried out.

DETAILED DESCRIPTION
[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0052] See also Figures 1 to 8 The present invention provides an automatic press-fitting device for processing the bottom ring of a fire extinguisher and a method for using the same. The technical solution is as follows:
[0053] An automatic pressing device for processing the bottom ring of a fire extinguisher comprises a bottle conveying platform 1, a bottom ring conveying platform 2, a pushing component 3, a pushing component 4, a top frame 5, a pressure component 6, a bottle end limit component 7, a flat plate 8, a positioning component 9 and a first stop bar 10. The end of the bottle conveying platform 1 is fitted with the side wall of the bottom ring conveying platform 2. The surface of the bottle conveying platform 1 is provided with an inclined surface. After the lower bottom seal of the fire extinguisher bottle is welded, it automatically falls from the welding production line onto the inclined surface and rolls downward by itself with the help of the inclined surface. Both sides of the bottom ring conveying platform 2 are constructed with notches in the same straight line direction as the fitting part of the bottle conveying platform 1. The fire extinguisher The bottle body moves from the gap on the side of the bottom ring conveyor platform 2 close to the bottle body conveyor platform 1 to the surface of the bottom ring conveyor platform 2. After the bottom ring of the fire extinguisher bottle body is pressed and installed, the fire extinguisher bottle body falls from the bottom ring conveyor platform 2 through the gap on the other side of the bottom ring conveyor platform 2; the pushing component 3 is installed on the surface of the bottom ring conveyor platform 2, and the pushing component 3 is used to push the bottom ring toward the side of the fire extinguisher bottle body to ensure that the bottom ring placed on the bottom ring conveyor platform 2 can move to the side of the fire extinguisher bottle body for replenishment by itself. The inner wall of the bottom ring conveyor platform 2 is constructed with a rectangular through groove, and the pushing component 4 is installed in the rectangular through groove. Under the action of the pushing component 4, the bottom ring moving toward the side of the fire extinguisher bottle body is pushed by the pushing component 4, further moves one body position to the side of the fire extinguisher bottle, thereby ensuring that the bottom ring fits with the end of the fire extinguisher bottle, the top frame 5 is installed between the top of the bottom ring conveying platform 2, the pressure component 6 is installed on the surface of the top frame 5, and the bottom of the pressure component 6 extends to the bottom of the top frame 5. After the pressure component 6 is started, the bottom ring that fits with the fire extinguisher bottle is pushed horizontally to press the bottom ring onto the fire extinguisher bottle. The bottle end limit component 7 is installed on the side of the bottom ring conveying platform 2 away from the pushing component 3, the flat plate 8 is installed on the surface of the bottom ring conveying platform 2, the positioning component 9 is installed between the surface of the flat plate 8 and the surface of the bottom ring conveying platform 2, and the first stop bar 10 Installed on the surface of the flat plate 8, the first baffle 10 is connected to the flat plate 8 through a pin shaft and a torsion spring, and the first baffle 10 is vertically distributed in a natural state. When the first baffle 10 is pushed laterally by the fire extinguisher bottle, it rotates from a vertical state to an inclined state. During the rotation of the first baffle 10, the positioning assembly 9 turns up and resists the subsequent fire extinguisher bottle. When the first baffle 10 is tilted to a specific angle, the bottle end limit assembly 7 drives the fire extinguisher bottle to rotate and press the first baffle 10 to a horizontal state and rolls off the surface of the flat plate 8. After the first baffle 10 loses the extrusion of the fire extinguisher bottle, it returns to a vertical state from a horizontal state, and the fire extinguisher bottle rolls down along the surface of the bottle conveying platform 1;When the first fire extinguisher bottle rolls onto the surface of the flat plate 8, it rolls to the surface of the flat plate 8 under the action of inertia and pushes the first stop bar 10 to one side of the rolling forward direction. The first stop bar 10 deflects accordingly. When the first stop bar 10 deflects, it presses the positioning component 9 downward, causing the internal angle of the positioning component 9 to change. The end of the positioning component 9 away from the flat plate 8 turns up, on the one hand, intercepting the fire extinguisher bottle that continues to roll down on the bottle conveying platform 1, and on the other hand, resisting the fire extinguisher bottle that rolls to the surface of the flat plate 8. In addition, the downward pressure of the fire extinguisher bottle on the bottle conveying platform 1 on the positioning component 9 is balanced with the pressing force of the positioning component 9 on the fire extinguisher bottle on the flat plate 8. When the angle of the positioning component 9 changes, During the process, the control panel is powered on by changing the angle, and the control panel sequentially powers on the push assembly 4, the pressure assembly 6, and the bottle end limit assembly 7 through the timer. The push assembly 4 horizontally pushes the bottom ring to fit the fire extinguisher bottle body and then resets. The pressure assembly 6 first moves down and then horizontally pushes the bottom ring to press the fire extinguisher bottle body and then resets. The bottle end limit assembly 7 drives the fire extinguisher bottle body on the flat plate 8 to rotate and then reset. After the fire extinguisher bottle body rotates and pushes the first stop bar 10 to a horizontal state, the fire extinguisher bottle body on the flat plate 8 rolls down from the gap on the edge of the bottom ring conveying platform 2, and then the first stop bar 10 loses the squeeze of the fire extinguisher bottle body on the flat plate 8 and returns to a vertical state, and the positioning assembly 9 resets at the same time. ;
[0054] In the present invention, during the automatic press-fitting operation of the bottom ring of the fire extinguisher, the fire extinguisher bottle body used has the lower bottom seal welded and the upper bottom seal in a welded state, and the upper bottom seal is welded after the bottom ring is press-fitted, so that the fire extinguisher bottle body can be driven to rotate through the bottle end limit assembly 7; in addition, the bottom ring to be press-fitted is trumpet-shaped, and the large-diameter end has a larger contact range with the ground, so that the fire extinguisher can be placed on the ground more stably; an arc-shaped groove is provided on the surface of the bottom ring conveying platform 2, and when the bottom rings are in contact with each other, the bottom ring is pushed toward the side of the bottom ring press-fitting station by applying pressure through the pushing assembly 3.
[0055] As an embodiment of the present invention, refer to Figure 1 and Figure 3The positioning assembly 9 includes a fixed column 92, a first transmission rod 93, a second transmission rod 94, a third transmission rod 95, a second stop bar 96, a fixed bar 97 and a pressure switch 98. The two fixed columns 92 are installed on the inner wall of the bottom ring conveying platform 2. The first transmission rod 93 is limited and slides between the outer periphery of the fixed columns 92. A compression spring 931 is abutted between the upper fixed column 92 and the inner wall of the first transmission rod 93. Under the action of the compression spring 931, when the first transmission rod 93 is not subjected to the deflection force of the first stop bar 10, the first transmission rod 93 can be in the highest position; the fixed bar 97 is installed at the bottom of the bottom ring conveying platform 2. The second transmission rod 94 and the third stop bar 10 are fixed. The transmission rods 95 are all hinged on the side wall of the fixed bar 97, the end of the second transmission rod 94 is in contact with the end of the first transmission rod 93, and the bottom of the second transmission rod 94 is installed with a bottom bar 941 whose bottom is in contact with the third transmission rod 95. Under the action of the bottom bar 941, when the first stop bar 10 is rotated by the fire extinguisher bottle to a certain angle, the first stop bar 10 rotates to press the first transmission rod 93 downward, and the bottom end of the first transmission rod 93 presses the second transmission rod 94 downward, so that the second transmission rod 94 presses the third transmission rod 95 through the bottom bar 941; the second stop bar 96 is rotatably installed on the surface of the bottom ring conveying platform 2, and the end of the third transmission rod 95 is in contact with the second stop bar 9 6, when the third transmission rod 95 rotates, the second stop bar 96 can be pushed upward, so that the second stop bar 96 turns up to intercept the falling fire extinguisher bottle, and the fire extinguisher bottle can be kept still during press-fitting by the gravity of the fire extinguisher bottle, thereby ensuring the press-fitting accuracy of the fire extinguisher bottle; the pressure switch 98 is installed on the side of the fixing bar 97 away from the bottom bar 941, the first stop bar 10 rotates to change the angle of the second transmission rod 94, the second transmission rod 94 rotates to change the angle of the third transmission rod 95, the third transmission rod 95 presses the pressure switch 98, switches the state of the pressure switch 98, and when the first stop bar 10 rotates, it squeezes downward The first transmission rod 93, the first transmission rod 93 is limited and moved by the fixed column 92, the bottom of the first transmission rod 93 presses the bottom of the second transmission rod 94 downward, the second transmission rod 94 pushes the third transmission rod 95 downward through the bottom bar 941, the third transmission rod 95 moves upward near one end of the second baffle 96, and flips the second baffle 96 up, the fire extinguisher bottle body is blocked by the first baffle 10 and remains stationary, the second baffle 96 flips up to block the fire extinguisher bottle body on the bottle body conveying platform 1, and when the third transmission rod 95 flips up near one end below the second baffle 96, the third transmission rod 95 applies pressure to the pressure switch 98, so that the pressure switch 98 is in the on state.
[0056] The pressure switch 98 is a conventional power switch. When the third transmission rod 95 is flipped up to a certain angle and continues to flip up, the pressure switch 98 is in the on state. At this time, the power of the control panel is continuously connected. The control panel controls the power-on time of the pushing component 4, the pressure component 6 and the bottle end limit component 7 through the timer, so that the above components can return to their original positions after completing the pressing action.
[0057] As an embodiment of the present invention, refer to Figure 1 , Figure 4 and Figure 5 The pushing assembly 4 includes a feeding motor 41, a reciprocating translation block 42, a vertical bar 43, a receiving groove 44, a telescopic rod 45 and an arc bar 46. The feeding motor 41 is installed on the side wall of the bottom ring conveyor platform 2. The reciprocating translation block 42 is slidably set in the rectangular through groove, and the side wall of the reciprocating translation block 42 is configured with an inclined groove 421. A turntable 411 is sleeved on the end of the output shaft of the feeding motor 41. A plug-in column 412 extending into the inclined groove 421 is rotatably installed on the side wall of the turntable 411. The plug-in column 412 is made of high-strength alloy material. When the plug-in column 412 extends to the inclined groove 421 and rotates, the wear resistance of the plug-in column 412 can be improved by the high-strength alloy material, thereby extending the service life of the plug-in column 412; the vertical bar 43 is installed at the end of the reciprocating translation block 42, the receiving groove 44 is configured on the side wall of the vertical bar 43, and the telescopic rod 45 is symmetrically installed in the receiving groove 44. The arc strip 46 is installed between the ends of the telescopic rod 45. When the feeding motor 41 rotates 180°, the reciprocating translation block 42 just completes a single stroke. When the power of the feeding motor 41 is just turned on, the reciprocating translation block 42 moves to one side of the bottle end limit assembly 7, and the reciprocating translation block 42 pushes the bottom ring in the same direction through the arc strip 46. After the feeding motor 41 rotates 180°, it continues to rotate 180° to restore the reciprocating translation block 42 to its initial state. When the arc strip 46 is blocked by the rear bottom ring, it shrinks into the accommodating groove 44 through the telescopic rod 45 until the arc strip 46 moves to the other end of the bottom ring. The telescopic rod 45 pops the arc strip 46 out of the accommodating groove 44, and the arc strip 46 fits against the side wall of the bottom ring to prepare for the next bottom ring push. The feeding motor 41 only needs to rotate in one direction, and there is no need to install an additional inverter to switch the rotation direction of the feeding motor 41.
[0058] As an embodiment of the present invention, refer to Figure 1 , Figure 6 and Figure 7, the pressure assembly 6 includes a hydraulic cylinder 61, a connecting plate 62, a limiting cylinder 63, a round rod 64, an electric lifting rod 65, a vertical rod 66, a bottom ring pushing strip 67, a straight slide groove 68 and a straight through groove 69, the straight slide groove 68 and the straight through groove 69 are both constructed on the top of the top frame 5, the vertical rod 66 slides through the straight through groove 69, and the side wall of the vertical rod 66 is slidably connected to the limiting slider 641. Under the action of the limiting slider 641, when the height of the vertical rod 66 changes, the end of the round rod 64 is fixedly connected to the limiting slider 641, and the round rod 64 can maintain an effective connection with the vertical rod 66 while keeping the height unchanged. The bottom ring pushing strip 67 is installed at the bottom of the vertical rod 66, and the round rod 64 slides through the limiting cylinder 63. The hydraulic cylinder 61 is installed on the surface of the top frame 5, and the connecting plate 62 is installed between the end of the round rod 64 and the end of the piston rod of the hydraulic cylinder 61. When the cylinder 61 contracts, the piston rod drives the vertical rod 66 to move horizontally through the connecting plate 62 and the round rod 64, thereby driving the bottom ring push bar 67 below to move horizontally, thereby completing the press-fitting operation of the bottom ring. An electric lifting rod 65 is installed on the surface of the vertical rod 66, and the bottom of the electric lifting rod 65 extends into the straight slide groove 68. When the electric lifting rod 65 contracts, the bottom ring push bar 67 moves downward, and when the electric lifting rod 65 extends, the bottom ring push bar 67 moves upward; the electric lifting rod 65 contracts after the power is turned on, thereby lowering the bottom ring push bar 67, so that the bottom ring fits in the arc groove of the bottom ring push bar 67. When the hydraulic cylinder 61 extends, it pushes the bottom ring to move toward the side of the fire extinguisher bottle through the connecting plate 62 and the round rod 64, and completes the press-fitting operation when the hydraulic cylinder 61 reaches the maximum stroke, and then the electric lifting rod 65 extends and the hydraulic cylinder 61 contracts to return to the initial position.
[0059] As an embodiment of the present invention, refer to Figure 1 and Figure 8The bottle end limiting assembly 7 includes a horizontal push rod 71, a mounting frame 72, a limiting frame 73, a rotating motor 74, an end plate 75 and a wedge-shaped rubber ring 76. The horizontal push rod 71 is installed between the inner walls of the mounting frame 72, the mounting frame 72 is installed on the side wall of the bottom ring conveying platform 2, the limiting frame 73 is installed at the end of the horizontal push rod 71, the rotating motor 74 is installed on the inner wall of the limiting frame 73, the end plate 75 is connected to the output shaft of the rotating motor 74, the wedge-shaped rubber ring 76 is sleeved on the outer periphery of the end plate 75, and the outer periphery of the wedge-shaped rubber ring 76 is structured with a friction surface. Through the characteristics of the rubber material and the setting of the friction surface, when the rotating motor 74 drives the end plate 75 and the wedge-shaped rubber ring 76 to rotate, the fire extinguisher bottle body can be driven by the contact effect between the wedge-shaped rubber ring 76 and the fire extinguisher bottle body. The wedge-shaped rubber ring 76 made of rubber material will not cause wear on the end of the fire extinguisher bottle when it rubs against the end of the fire extinguisher bottle, thereby effectively ensuring the integrity of the fire extinguisher bottle; the horizontal push rod 71 pushes the end plate 75 and the wedge-shaped rubber ring 76 to fit with the end of the fire extinguisher bottle, and the rotating motor 74 drives the end plate 75 to rotate, and the end plate 75 drives the fire extinguisher bottle to rotate through the wedge-shaped rubber ring 76, and then the horizontal push rod 71 contracts, and the fire extinguisher bottle rotating at a certain speed pushes the first baffle 10 open, so that the first baffle 10 is in a horizontal state, and the fire extinguisher bottle falls from the flat plate 8. After the fire extinguisher bottle falls, the first baffle 10 returns to a vertical state under the action of the torsion spring, and the second baffle 96 returns to a horizontal state after losing the action of the third transmission rod 95.
[0060] As an embodiment of the present invention, refer to Figure 2 The pushing assembly 3 includes a compression rod 31 and a push plate 32. The compression rod 31 is installed on the surface of the bottom ring conveying platform 2. The push plate 32 is slidably installed between the outer periphery of the compression rod 31 and the surface of the bottom ring conveying platform 2. Under the action of the compression rod 31, the push plate 32 can be driven to move toward the side of the fire extinguisher bottle body, thereby allowing the bottom ring to be replenished to the side of the fire extinguisher bottle body by itself.
[0061] As an embodiment of the present invention, refer to Figure 8 The side walls of the end plates 75 are symmetrically provided with connecting strips 77, and the ends of the connecting strips 77 are fixed with limiting strips 78. The side walls of the limiting frame 73 are constructed with arc grooves adapted to the limiting strips 78. When the rotating motor 74 drives the end plate 75 to rotate, the rotation stability of the end plate 75 can be effectively improved, and the end plate 75 can be prevented from moving horizontally and separating from the output shaft of the rotating motor 74.
[0062] As an embodiment of the present invention, refer to Figure 3The hinged position of the third transmission rod 95 and the fixed bar 97 is located on the side of the third transmission rod 95 close to the bottom bar 941, and the contact part of the third transmission rod 95 and the second baffle bar 96 is arranged close to the rotating end of the second baffle bar 96. The design of the second transmission rod 94 and the third transmission rod 95 solves the problem that the rotation angle of the first baffle bar 10 is limited and it is unable to drive the second baffle bar 96 to rotate at a large angle, thereby realizing the interception of the fire extinguisher bottle body at the rear.
[0063] As an embodiment of the present invention, refer to Figure 7 The bottom cross-section of the vertical rod 66 is H-shaped, and a reinforcement block is installed between the side wall of the vertical rod 66 and the surface of the bottom ring push bar 67, which effectively improves the structural strength of the pressure component 6 and makes it difficult for the bottom ring push bar 67 to deform when moving.
[0064] A method for using an automatic press-fitting device for processing a bottom ring of a fire extinguisher comprises the following steps:
[0065] S1, the fire extinguisher bottle body with the lower head welded in advance but the upper head not welded flows to the surface of the bottle body conveyor platform 1 through the welding production line, and rolls along the inclined surface of the bottle body conveyor platform 1 to the surface of the bottom ring conveyor platform 2;
[0066] S2. When a single fire extinguisher bottle rolls to the surface of the flat plate 8, the fire extinguisher bottle pushes the first stop bar 10 sideways, and the first stop bar 10 deflects a certain angle toward the forward side of the fire extinguisher bottle. During the process of the first stop bar 10, the first transmission rod 93 is continuously pressed downward, and the first transmission rod 93 is limited by the fixed column 92. The bottom of the first transmission rod 93 presses the bottom of the second transmission rod 94 downward, and the second transmission rod 94 pushes the third transmission rod 95 downward through the bottom bar 941. The third transmission rod 95 moves upward near one end of the second stop bar 96, and the second stop bar 96 is turned up. The rear end of the second stop bar 96 is turned up and presses against the fire extinguisher bottle that has moved to the flat plate 8 from below, and prevents the fire extinguisher bottle on the bottle conveying platform 1 from continuing to roll toward the flat plate 8.
[0067] S3, when the second stop bar 96 turns up, the pressure switch 98 is squeezed, the pressure switch 98 turns on the power of the control panel, and the control panel sequentially turns on the power of the feeding motor 41, the hydraulic cylinder 61, the electric lifting rod 65, the horizontal push rod 71 and the rotating motor 74 through the delay device;
[0068] The output shaft of the feeding motor 41 drives the plug 412 to make a circular motion in the inclined slot 421 through the turntable 411. When the plug 412 moves to the horizontal positions at both ends of the inclined slot 421, the moving direction of the reciprocating translation block 42 is switched. When the feeding motor 41 rotates 180°, the reciprocating translation block 42 completes a single stroke. When the power of the feeding motor 41 is just turned on, the reciprocating translation block 42 moves to one side of the bottle end limit assembly 7. The reciprocating translation block 42 pushes the bottom circle in the same direction through the arc bar 46. After the power of the feeding motor 41 is turned on, it rotates one circle and then the power is turned off. When it rotates 180° subsequently, the reciprocating translation block 42 drives the arc bar 46 to reset.
[0069] After the electric lifting rod 65 is powered on, it contracts and lowers the bottom ring push bar 67. The bottom ring fits into the arc groove of the bottom ring push bar 67. The hydraulic cylinder 61 extends and pushes the bottom ring to move toward the side of the fire extinguisher bottle through the connecting plate 62 and the round rod 64, and presses the bottom ring onto the fire extinguisher bottle. Then the electric lifting rod 65 and the hydraulic cylinder 61 are reset and the power is disconnected.
[0070] The horizontal push rod 71 pushes the end plate 75 and the wedge-shaped rubber ring 76 to fit with the end of the fire extinguisher bottle body, and the rotary motor 74 drives the end plate 75 to rotate. The end plate 75 drives the fire extinguisher bottle body to rotate through the wedge-shaped rubber ring 76, and then the horizontal push rod 71 contracts, and the fire extinguisher bottle body rotating at a certain speed pushes the first stop bar 10, and the first stop bar 10 changes from an inclined state to a horizontal state. At this time, the rotating fire extinguisher bottle body falls from the edge gap of the bottom ring conveying platform 2. After the fire extinguisher bottle body falls, the first stop bar 10 returns to a vertical state, and the second stop bar 96 returns to a horizontal state after losing the action of the third transmission rod 95;
[0071] S4. After the next fire extinguisher bottle is moved onto the flat plate 8, the above steps S1-S3 are repeated to realize the automatic press-fitting operation of the bottom ring of the fire extinguisher.
[0072] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.

9. A method for using an automatic press-fitting device for processing a bottom ring of a fire extinguisher, characterized in that: The following steps are involved: S1, the fire extinguisher bottle body, which has been pre-welded with the lower head but not the upper head, flows through the welding production line to the surface of the bottle body conveyor platform (1), and rolls along the inclined surface of the bottle body conveyor platform (1) toward the surface of the bottom ring conveyor platform (2); S2. When a single fire extinguisher bottle rolls onto the surface of the flat plate (8), the fire extinguisher bottle pushes the first stop bar (10) sideways, and the first stop bar (10) deflects a certain angle toward the forward side of the fire extinguisher bottle, and continuously presses the first transmission rod (93) downward during the first stop bar (10). The first transmission rod (93) moves in a limited position through the fixed column (92), and the bottom of the first transmission rod (93) presses the bottom of the second transmission rod (94) downward, and the second transmission rod (94) pushes the third transmission rod (95) downward through the bottom bar (941). The third transmission rod (95) moves upward near one end of the second stop bar (96), and flips the second stop bar (96) upward. The rear end of the flipped second stop bar (96) presses against the fire extinguisher bottle that has moved onto the flat plate (8) from below, and prevents the fire extinguisher bottle on the bottle conveying platform (1) from continuing to roll toward the flat plate (8); S3, when the second stop bar (96) turns upward, the pressure switch (98) is squeezed, the pressure switch (98) is connected to the power supply of the control panel, and the control panel is connected to the power supply of the feeding motor (41), the hydraulic cylinder (61), the electric lifting rod (65), the horizontal push rod (71) and the rotating motor (74) in sequence through the delay device; The output shaft of the feeding motor (41) drives the plug (412) to make a circular motion in the inclined groove (421) through the rotating disk (411). When the plug (412) moves to the horizontal position at both ends of the inclined groove (421), the moving direction of the reciprocating translation block (42) is switched. When the feeding motor (41) rotates 180°, the reciprocating translation block (42) completes a single stroke. When the power of the feeding motor (41) is just turned on, the reciprocating translation block (42) moves to one side of the bottle end limit assembly (7). The reciprocating translation block (42) pushes the bottom ring in the same direction through the arc strip (46). After the power of the feeding motor (41) is turned on, it rotates one circle and then the power is turned off. When it rotates 180° later, the reciprocating translation block (42) drives the arc strip (46) to reset. After the electric lifting rod (65) is powered on, it contracts and lowers the bottom ring push bar (67). The bottom ring fits into the arc groove of the bottom ring push bar (67). The hydraulic cylinder (61) extends to push the bottom ring toward the side of the fire extinguisher bottle through the connecting plate (62) and the round rod (64), and the bottom ring is pressed onto the fire extinguisher bottle. Then, the electric lifting rod (65) and the hydraulic cylinder (61) are reset and the power is disconnected. The horizontal push rod (71) pushes the end plate (75) and the wedge-shaped rubber ring (76) to fit with the end of the fire extinguisher bottle body, and the rotating motor (74) drives the end plate (75) to rotate. The end plate (75) drives the fire extinguisher bottle body to rotate through the wedge-shaped rubber ring (76). Then the horizontal push rod (71) contracts, and the fire extinguisher bottle body rotating at a certain speed pushes the first stop bar (10). The first stop bar (10) changes from an inclined state to a horizontal state. At this time, the rotating fire extinguisher bottle body falls from the edge gap of the bottom ring conveying platform (2). After the fire extinguisher bottle body falls, the first stop bar (10) returns to a vertical state, and the second stop bar (96) returns to a horizontal state after losing the action of the third transmission rod (95); S4. After the next fire extinguisher bottle is moved onto the flat plate (8), the above steps S1-S3 are repeated to achieve the automatic press-fitting operation of the bottom ring of the fire extinguisher.
