Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguisher inner molding, in particular to an air supply structure of an anti-corrosion inner molding machine of a fire extinguisher. Background Art

[0002] Fire extinguishers are currently the most common fire-fighting equipment and are generally stored in various public places for emergency use.

[0003] At present, there are many types of fire extinguishers, including fire extinguishers that use various chemical agents as extinguishing agents (such as water-based fire extinguishers). However, these chemical agents are corrosive to the fire extinguisher cylinder (or bottle). Therefore, before filling the fire extinguishing agent, the inner wall of the fire extinguisher cylinder needs to be treated with anti-corrosion. The process of anti-corrosion treatment of the inner wall of the fire extinguisher cylinder is called "internal plastic".

[0004] According to the "internal molding" process of fire extinguishers, various forms of internal molding machines have appeared in the market, such as: a fire extinguisher anti-corrosion internal molding device disclosed in the authorization announcement number CN214971444U. Although the existing internal molding has the basic heating function and drives the fire extinguisher cylinder to rotate during the heating process, it still has the following shortcomings:

[0005] 1. The fixed fire extinguisher cylinder flip plate cannot adapt to fire extinguisher cylinders of different sizes. Therefore, only one specification of fire extinguisher cylinder can be processed with the corresponding internal molding process;

[0006] 2. After the flip plate is installed on the cylinder, the overall weight increases, and the overall weight increases at different rates according to the weight of the cylinder of the fire extinguisher of different specifications. At present, the control drive of the flip plate is mainly undertaken by the motor, so the main shaft of the motor (also called the drive shaft or motor shaft) needs to bear a large torque, which easily causes the motor to be scrapped;

[0007] 3. The current internal molding machine does not have the corresponding cooling function after heating the fire extinguisher cylinder. Therefore, special cooling equipment is required for cooling, so there is a disadvantage of imperfect function.

[0008] In summary, necessary improvements need to be made to the existing internal molding machines to solve the above-mentioned defects. Utility Model Content

[0115] Example 1

[0116] like Figure 1-5 As shown, the utility model discloses a fire extinguisher anti-corrosion inner molding machine, comprising:

[0117] The clamping structure 10 is used for mounting the fire extinguisher cylinder;

[0118] The flip structure 20 is used for hinged installation of the clamping structure 10;

[0119] The air supply structure 30 has a plurality of heating ends for heating the cylinder of the fire extinguisher;

[0120] The flip structure 20 can drive the clamping structure 10 to rotate clockwise or counterclockwise based on the hinge position; in this embodiment: the clamping structure includes:

[0121] A first frame 101;

[0122] The limiting side plate 102 is slidably disposed on the first frame 101, and the first frame 101 is provided with a slide rail 101c;

[0123] A driving module is installed on the first frame 101 and is capable of driving the limiting side plate 102 to move;

[0124] The rotating module is installed on the first frame 101 and can drive the cylinder of the fire extinguisher to rotate;

[0125] Among them, the limiting side plates 102 form an installation area for installing the fire extinguisher cylinder;

[0126] When the driving module drives the limiting side plates 102 to approach each other, the installation area is reduced;

[0127] When the driving module drives the limiting side plates 102 to move away from each other, the installation area is expanded.

[0128] In this embodiment: the driving module is composed of a first rack 41 and a second rack 42 slidably disposed on the first frame 101, and a gear 43 meshing with the first rack 41 and the second rack 42 is disposed between the first rack 41 and the second rack 42;

[0129] Among them, the first rack 41 or the second rack 42 can be controlled to move by the first hydraulic cylinder 44, and the limiting side plate 120 is installed on the first rack 41 and the second rack 42. That is to say, a first driving chamber 45 for the first rack 41, the second rack 42 and the gear 43 to move is provided on the first frame 101.

[0130] In this embodiment, the first frame 101 is respectively composed of a first part 101a and a second part 101b, and the first parts 101a and 101b are arranged to slide relative to each other, wherein the second part 101b is hinged to the flip structure 20, and the first part 101a is controlled by a first cylinder 46 installed on the second part 101b to control the lifting movement. In more detail, a lifting frame 47 is provided on the second part 101b, and the lifting frame 47 has a lifting connection shaft 47a passing through the second part 101b, and the lifting connection shaft 47a is connected to the first part 101a, and a supporting structure is provided on another lifting connection shaft 47a, and the supporting structure is composed of a first support plate 48 and a support disk 49, and the support disk 49 is controlled to move by a second cylinder 49a installed on the first support plate 48, and the first support plate 48 is rotatably connected to the piston shaft of the second cylinder 49a.

[0131] In this embodiment, the driving module is arranged in the second part 101b of the first frame, and a rotating module is provided on the first part 101a of the first frame 101. The rotating module includes a rotating nozzle 50 and a sprocket structure. The rotating nozzle 50 is installed on the second part 102a of the first frame 101 through a second support plate (that is, the first part 101a of the first frame). The rotating nozzle 50 of this embodiment is driven to rotate by a first motor and a sprocket structure 52 (composed of a sprocket 520 and a chain 521).

[0132] In this embodiment, the air cylinder can be replaced by a hydraulic cylinder according to actual conditions to ensure the stability of operation.

[0133] refer to Figure 1-5 , the principle of this embodiment is:

[0134] When the clamping structure is in use, the fire extinguisher cylinder is placed between the limiting side plates, and the second cylinder is driven to control the support plate to move, and after contacting the bottom of the fire extinguisher cylinder, the bottle mouth of the fire extinguisher cylinder is driven to approach the rotating plug nozzle, thereby completing the fixing of the fire extinguisher cylinder;

[0135] By controlling the rotation of the sprocket structure, the rotating plug nozzle can be driven to rotate, and the fire extinguisher cylinder can be driven to rotate, and the inner plastic material can be added into the fire extinguisher cylinder through the rotating plug nozzle.

[0136] In this embodiment, the first rack can be controlled to move by controlling the first cylinder, and the second rack can be driven to move by the gear, so as to achieve the purpose of controlling the movement of the limiting side plate. When the limiting side plate moves, the distance between the two is enlarged (the installation area is enlarged), and when the distance between the two is reduced (the installation area is reduced), it can adapt to the installation of fire extinguisher cylinders of different sizes. According to the support of different fire extinguisher cylinders, the first cylinder can be used to control the lifting and lowering activities of the first support plate and the second support plate (the first part of the first frame), so that the bottle mouth of the fire extinguisher cylinder can be coaxially arranged with the support plate and the rotating plug nozzle, so as to drive the fire extinguisher cylinder to rotate normally.

[0137] It should be noted that: the flip structure and air supply structure in this embodiment can be referred to the following embodiments.

[0138] Embodiment 2 is different from Embodiment 1 in that

[0139] like Figure 6-8 As shown, the rotation module of this embodiment includes:

[0140] The claw 6 is mounted on the second portion 101b of the first frame through the first support plate 48;

[0141] The second cylinder 49a is mounted on the first support plate 48 and is used to control the movement of the claw 6;

[0142] The rotating plug nozzle 50 is installed on the second part 101b of the first frame through the second support plate (equivalent to the first part 101a of the first frame in embodiment 1);

[0143] The first motor (not shown in the figure, disposed in the second part 101b of the first frame) is used to drive the rotating plug nozzle 50 to rotate. The method of driving the rotating plug nozzle 50 in this embodiment is the same as that in embodiment 1, so it can be referred to in the embodiment part;

[0144] The rotating nozzle 50 has a feeding port 50 a extending therethrough, and a material container 53 is detachably connected to one end of the rotating nozzle 50 away from the claw 6 .

[0145] In this embodiment: the claw 6 includes:

[0146] A claw plate 60 connected to the piston shaft 49b of the second cylinder 49a;

[0147] The hinge grooves 61 are recessed on the claw plate 60 and are distributed at equal intervals around the center of the claw plate 60;

[0148] A plurality of claw bodies 62 are rotatably connected to each hinge groove 61 through a rotating pin 62a;

[0149] A compression spring 63 is connected between the claw body 62 and the bottom of the hinge groove 61;

[0150] A clamping area 62b for clamping the bottom of the fire extinguisher cylinder is formed between the claws 62.

[0151] In this embodiment: the material container 53 includes:

[0152] The container body 530 has a material cavity, and the mouth of the container body 530 is provided with external threads;

[0153] The anti-corrosion film 531 is adapted to the cavity wall of the material cavity and connected to the bottle mouth of the container body 530;

[0154] Wherein, an air filling cavity 532 is formed between the anti-corrosion film 531 and the material cavity, and an air filling valve 533 communicating with the air filling cavity 532 is formed on the container body 530;

[0155] The anti-corrosion film 531 can be inserted into or removed from the material cavity from the bottle mouth of the container body 530 .

[0156] refer to Figure 6-8 This embodiment provides a variation of a rotation module, which is different from the rotation module of Embodiment 1 in at least the following aspects:

[0157] The support plate structure in Example 1 is improved into a claw structure, and the claw can improve the clamping ability of the fire extinguisher cylinder. When in use, when the claw approaches the fire extinguisher cylinder and abuts against the bottom of the fire extinguisher cylinder, the claw is stressed and squeezes the compression spring, and the compression spring drives the claw body of the claw to contact the fire extinguisher cylinder more closely; moreover, the structure of the claw is similar to the structure of human fingers, so that the fire extinguisher cylinder can be better fixed;

[0158] Secondly, the difference between this embodiment and the first embodiment is that a material container is provided, and the material container can be used to load the inner plastic material. Therefore, when the fire extinguisher cylinder is installed, it is not necessary to pre-fill the inner plastic material inside, so that leakage of the inner plastic material during installation can be avoided; after the inner plastic material is loaded into the material container, it is installed on the rotating plug nozzle, and the inner plastic material inside can be poured into the fire extinguisher cylinder through the turning structure and the trend of the rotating module;

[0159] Moreover, the anti-corrosion film disposed inside the material container of this embodiment can be taken out from the bottle mouth of the material container, thereby facilitating cleaning, and the inflation valve disposed at the bottom of the material container can inflate the inflation cavity, thereby assisting in taking out the anti-corrosion film inside the material container.

[0160] Example 3

[0161] like Figure 1 As shown, this embodiment provides a schematic diagram of a flip structure, and the flip structure 20 includes:

[0162] The second frame 200 has a flipping area;

[0163] A rotating shaft, rotatably connected in the flipping area and connected to the second portion 101b of the first frame 101;

[0164] The driven gear 201 is connected to the rotating shaft;

[0165] The driving rack 202 is slidably disposed on the second frame 200 and meshes with the driven gear 201;

[0166] The second frame 200 is provided with a second hydraulic cylinder 203 for controlling the movement of the driving rack 202 .

[0167] refer to Figure 1 The flipping structure of this embodiment replaces the flipping method of the clamping structure driven by a motor in the prior art, and is more stable. In detail: when driving the driven gear to rotate clockwise and counterclockwise alternately (that is, when driving the clamping structure to flip), the motor driving method of the prior art will cause the motor shaft of the motor to bear a large torque, so it is very easy to be damaged. However, this embodiment is driven by a hydraulic cylinder, so there is no need to worry about this problem.

[0168] Embodiment 4 is different from Embodiment 1 in that

[0169] like Figure 9-10 As shown, in this embodiment: a safety spring 202 a is connected between any end of the driving rack 202 and the second frame 200 .

[0170] In this embodiment, a limiting groove 202b is provided on the driving rack 202, and a lock 24 movable in the limiting groove 202b is provided on the second frame 200, wherein the lock 24 includes:

[0171] The female buckle 240 is fixedly disposed on the second frame 200 and is located on one side of the driving rack 202;

[0172] A slot 241 is formed on the female buckle 240;

[0173] The sub-button 242 is detachably disposed on the second frame 200 and has an inserting block 242a inserted into the slot 241;

[0174] The female buckle 240 and the plug block 242 a are provided with coaxially arranged threaded holes 243 , and the female buckle 240 is provided with fastening bolts 244 that can pass through the threaded holes 243 in sequence.

[0175] In this embodiment: the second frame 200 and the sub-button 242 are provided with a dovetail groove 245 and a dovetail plug 246 that are adapted to each other.

[0176] In this embodiment: a nozzle 247 for spraying air toward the driving rack 202 is installed on the sub-button 242, and an air suction structure for supplying air to the nozzle is provided on the second frame 200, wherein the air suction structure includes:

[0177] The suction body 2480 has a suction cavity 2481;

[0178] A one-way air inlet nozzle 2482 communicates with the air suction cavity 2481;

[0179] A one-way exhaust nozzle 2483 is connected to the air suction cavity 2481;

[0180] Among them, a pumping gas 2485 connected to the piston shaft of the second hydraulic cylinder 203 through a linkage shaft 2484 moves inside the suction gas 2480. In this embodiment, the linkage shaft 2484 is connected between the driving rack 202 and the pumping gas 2485.

[0181] refer to Figure 9-10 The principle of this embodiment is that when the driving rack is controlled to move by the second hydraulic cylinder, it can not only drive the clamping structure to move, but also make the suction gas move back and forth in the suction chamber, forming a negative pressure in the suction chamber and sucking in gas, and when the suction chamber is squeezed by the suction gas, the gas is discharged and sprayed out from the nozzle, thereby cleaning the meshing tooth end surface of the driving rack, ensuring smooth cooperation between the driven gear and the driving rack, and avoiding foreign matter from affecting the cooperation between the two.

[0182] Moreover, the safety spring and the lock provided in the present embodiment can limit the movement of the driving rack. If the hydraulic cylinder is damaged, the movement of the driving rack can be limited, that is, when any end groove wall of the limiting groove on the driving rack contacts the lock, the movement will stop. This can shorten the movement stroke of the clamping structure due to damage to the hydraulic cylinder, thereby preventing the clamping structure from getting out of control and causing the fire extinguisher cylinder to be thrown out.

[0185] The gas supply branch at least comprises a first gas supply branch connected between the gas source and the gas igniter 300 and a second gas supply branch connected between the gas source and the cooling nozzle 301 .

[0186] In this embodiment: the gas supply branch includes:

[0206] The principle of this embodiment is:

[0207] When the fire extinguisher cylinder is molded, the electromagnet is energized and drives the movable body to move to the left, and opens the connection between the second gas pipe and the second cavity. At this time, the gas in the gas source enters the second cavity and is then sent to each gas igniter to complete the gas supply. In other words, the second gas pipe, the second cavity and the first gas pipe constitute a first gas supply branch.

[0208] When the fire extinguisher cylinder is cooled, the electromagnet is powered off, and the movable body is controlled by the return spring to move to the right, closing the connection between the second gas pipe and the second cavity, and opening the connection between the first cold air pipe and the first cavity. The fan delivers the gas into the air inlet cavity through the second cold air pipe, and the gas is cooled by the heat exchanger, then filtered through the filter and discharged from the first cold air pipe, and sprayed out from the cooling nozzle to cool the fire extinguisher cylinder. In other words, the second cold air pipe, the first cavity and the first cold air pipe constitute a second air supply branch.

[0209] It should be noted that:

[0210] In this embodiment, the coolant can be delivered into the heat exchange chamber through the first connecting nozzle and the second connecting nozzle, that is, the coolant can be delivered from the first connecting nozzle and discharged from the second connecting nozzle after passing through the heat exchange chamber; when supplying air to the first chamber, the impurities can be filtered and concentrated in the air intake chamber, and the impurities in the air intake chamber can be cleaned by disassembling the cooling body.
