Description

TECHNICAL FIELD

[0001] The application relates to the technical field of bottle mouth threads, and particularly relates to a bottle mouth thread processing equipment for manufacturing fire extinguishers. BACKGROUND

[0002] A fire extinguisher is a core fire-fighting equipment for responding to initial fires. The fire extinguisher sprays dry powder, water, carbon dioxide and other fire extinguishing media to block the three elements (combustible material, combustion-supporting material and ignition source) of combustion to achieve fire extinguishing. The fire extinguisher is widely applied to various scenes such as families, office buildings, factories and vehicles. As a typical pressure container, the sealing performance and pressure safety of the fire extinguisher directly depend on the bottle mouth thread, which is a core structure connecting the bottle body and the valve. The equipment for processing the bottle mouth thread is a key process equipment in the manufacturing of the fire extinguisher. The core function of the equipment is to accurately process the thread on the bottle mouth to meet the sealing requirements, so as to finally ensure that there is no leakage after the bottle valve is assembled and to guarantee the overall safety performance of the fire extinguisher.

[0003] When the inner thread of the fire extinguisher tank is processed, metal scraps are inevitably generated in the processing process. The scraps are easy to enter the inner cavity of the tank. In order to avoid the influence of the residual scraps on the subsequent assembly sealing performance or cause safety hazards, manual cleaning is usually required in the tank. The additional process not only increases the labor cost, but also interrupts the continuity of the processing process, which brings inconvenience to the overall production work. SUMMARY

[0013] This invention provides a device for machining the thread on the bottle neck of a fire extinguisher. It has the following beneficial effects:

[0014] 1. The bottle neck thread processing equipment for this fire extinguisher is equipped with a positioning component. The positioning frame of the feeding seat and the connecting seat together cover the canister, rather than a single point hard clamp. This increases the clamping contact area, disperses the clamping force, and avoids excessive local pressure that could cause the canister to dent. The inclined surface design and buffer shrinkage of the positioning block provide suitable space for the canister to enter the feeding seat positioning seat, avoiding canister jamming and machine stoppage due to block obstruction.

[0015] 2. The cylinder neck thread processing equipment for this fire extinguisher is equipped with a buffer mechanism. Through the synchronous design of the connecting shaft sliding groove, the two positioning blocks can maintain a consistent sliding rhythm when subjected to extrusion pressure. This prevents situations where one side of the positioning block gets stuck and the other side deviates excessively, and also prevents the fire extinguisher canister from getting stuck in the positioning seat due to asynchronous movement of the positioning blocks. This synchronicity ensures that the canister moves smoothly along the preset path during loading, transfer and other processes, reducing production interruptions caused by mechanism jamming.

[0016] 3. The bottle mouth thread processing equipment for fire extinguisher manufacturing is provided with a feeding component, a negative pressure adsorption of an air suction mechanism is used to replace hard clamping transfer, a feeding plate is flexibly abutted with one end surface of the tank body, uniform stress fixation is realized through negative pressure, extrusion damage to the just cut bottle mouth is avoided, positioning frame auxiliary limiting is also provided, tank body shaking during transfer is prevented, deformation of the tank mouth caused by secondary clamping is avoided, thread integrity is guaranteed, after the tank body cut is transferred to the cleaning component, the feeding seat does not need to wait for cleaning to end, and the feeding process of the next tank body to be processed can be started synchronously.

[0017] 4. The bottle mouth thread processing equipment for fire extinguisher manufacturing is provided with a cleaning mechanism, contact cleaning and airflow jetting double-acting are used to solve the problem of single cleaning residual impurities, ensure that there is no debris in the tank to affect the subsequent sealing performance, debris is concentrated and collected for recycling, reduce waste pollution, reduce the workload of equipment cleaning and maintenance, and improve overall production efficiency.

[0018] 5. The bottle mouth thread processing equipment for fire extinguisher manufacturing is provided with a contact assembly, the cleaning plate is expanded by centrifugal force, the opening amplitude of the cleaning plate can be automatically adjusted according to the inner diameter of the fire extinguisher tank, contact with the inner wall of the tank body of different specifications is ensured, cleaning dead angles caused by small diameter differences are avoided, and cleaning coverage is improved.

[0030] Embodiment one, please refer to Figures 1-2 The present application provides a technical solution: a bottle mouth thread processing equipment for manufacturing fire extinguishers, comprising:

[0031] The cutting part 1 is used for thread processing work on the bottle mouth of the fire extinguisher;

[0032] The feeding part 2 is used for cutting feeding work on the fire extinguisher, the side surface of the feeding part 2 is fixedly connected with the cutting part 1, the side surface of the feeding part 2 is fixedly connected with the connecting seat 3, both sides of the top of the connecting seat 3 are fixedly connected with the positioning part 5, the number of the positioning part 5 is three, the side of the connecting seat 3 away from the feeding part 2 is fixedly connected with the cleaning part 4, and the top of the side of the connecting seat 3 close to the cleaning part 4 is provided with the collecting groove 6;

[0033] Please refer to Figures 3-4The positioning component 5 comprises positioning seats 51, the inner side of one positioning seat 51 is in sliding connection with the side surface of the two guide rods 26, the inner side of one positioning seat 51 is in sliding connection with the side surface of the feeding seat 21, the side surface of one positioning seat 51 is in threaded connection with the side surface of the transmission mechanism 25, the side surfaces of two positioning seats 51 are fixedly connected with the top of the connecting seat 3, the side surface of the positioning seat 51 is fixedly connected with the fourth driving part 52, the output end of the fourth driving part 52 is fixedly connected with the positioning frame 53, the two sides of the top of the positioning seat 51 are fixedly connected with the positioning plates 57, the two sides of the top of the positioning seat 51 close to the positioning plates 57 are slidably connected with the positioning blocks 54, the bottom of the positioning block 54 is fixedly connected with the buffer mechanism 56, and the inner side of the positioning seat 51 is provided with a sliding groove 55;

[0034] Firstly, the fire extinguisher tank is placed on the positioning seat 51 of the connecting seat 3 away from the cleaning component 4, and specifically between the two positioning plates 57 and the two positioning blocks 54 of the positioning seat 51, so as to complete the initial positioning.

[0035] Subsequently, the transmission mechanism 25 of the feeding seat 21 is started to drive the positioning seat 51 of the feeding seat 21 to move until the positioning seat 51 is in the same direction and abuts against the positioning seat 51 of the connecting seat 3 on which the tank body is placed, then the fourth driving part 52 of the positioning seat 51 on the top of the feeding seat 21 is started, the output end of the fourth driving part 52 drives the positioning frame 53 to move, and the positioning frame 53 abuts against the positioning frame 53 of the positioning seat 51 on the top of the connecting seat 3 to jointly form “clamping covering” for the fire extinguisher tank, so as to realize the preliminary fixing of the tank body.

[0036] Next, the fourth driving part 52 of the positioning seat 51 of the feeding seat 21 is synchronously adjusted in the reverse direction, and the fourth driving part 52 of the positioning seat 51 of the connecting seat 3 is started: the output end of the fourth driving part 52 of the connecting seat 3 drives the tank body through the positioning frame 53 to move towards the positioning seat 51 of the feeding seat 21; during the movement, the positioning frame 53 generates extrusion force on the tank body, so as to promote the tank body to extrude the positioning blocks 54 on the two sides of the top of the positioning seat 51 of the feeding seat 21, after extrusion, the positioning blocks 54 move to the inner side of the positioning seat 51 through the buffer mechanism 56, and at the same time, since the side away from the positioning plate 57 of the positioning block 54 is provided with an inclined surface, when the connecting frame of the connecting seat 3 with the tank body enters the feeding seat 21, the two positioning blocks 54 on the two sides of the positioning seat 51 of the feeding seat 21 are synchronously extruded to shrink into the positioning seat 51 through the buffer mechanism 56, so as to make space for the tank body.

[0037] After the positioning frame 53 completely sends the fire extinguisher tank into the positioning seat 51 of the feeding seat 21, the tank body abuts against the two positioning plates 57 of the positioning seat 51 of the feeding seat 21 to complete the final positioning; at this time, the extrusion force disappears, the positioning blocks 54 are reset through the buffer mechanism 56 to re-tightly abut against the tank body, so as to realize stable limiting, finally, the fourth driving part 52 of the positioning seat 51 on the top of the connecting seat 3 is adjusted to reset, and the whole feeding positioning process is completed.

[0038] Please refer toFigure 5 The buffering mechanism 56 comprises a connecting shaft 561, the side surface of the connecting shaft 561 is in sliding connection with the inner side of the sliding groove 55, both ends of the connecting shaft 561 are fixedly connected with sliding rods 562, the top of the sliding rod 562 is fixedly connected with the bottom of the positioning block 54, the bottom of the sliding rod 562 is in sliding connection with the inner side of the positioning seat 51, the sliding rod 562 is sleeved with a first spring 563, the top of the first spring 563 is fixedly connected with the top of the positioning block 54, and the bottom of the first spring 563 is fixedly connected with the inner side of the positioning seat 51;

[0039] When the positioning frame 53 drives the fire extinguisher tank to move and generates extrusion force on the two positioning blocks 54, the positioning block 54 slides to the inner side of the positioning seat 51 through the sliding rod 562, and simultaneously extrudes the first spring 563 sleeved on the sliding rod 562; since the two sliding rods 562 are connected with the connecting shaft 561, and the connecting shaft 561 can slide in the sliding groove 55 on the inner side of the positioning seat 51, when the positioning block 54 moves under the extrusion force, the two positioning blocks 54 can keep consistent action through the synchronous sliding of the connecting shaft 561, so that the smooth movement of the fire extinguisher tank is avoided due to unilateral deviation;

[0040] When the fire extinguisher tank completely passes through the two positioning blocks 54, the extrusion force of the tank on the positioning block 54 disappears, the first spring 563 that is compressed releases elastic force, and the positioning block 54 is pushed to move upward through the sliding rod 562 and the connecting shaft 561 to reset; the two positioning blocks 54 after resetting are repositioned against the fire extinguisher tank on the positioning seat 51, and the positioning of the tank is completed;
