Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically a fire extinguisher cylinder spraying equipment. Background Technology

[0002] Fire extinguishers are a common type of fire-fighting equipment. In daily life and production, fire extinguishers are one of the most common fire prevention facilities. They are stored in factories or public places to facilitate fire extinguishing operations when a fire occurs. During the production and processing of fire extinguishers, the surface of the fire extinguisher cylinder is usually sprayed to improve its corrosion resistance.

[0003] Chinese Patent Publication No. CN222695119U discloses a spraying device for fire extinguisher production. The device is designed to drive a drive shaft via a limit seat and a drive motor. The drive shaft and the rotating shaft are connected by a transmission mechanism. The limit seat is rotatably mounted on a support base via the rotating shaft. Multiple rotating shafts are meshed with gears to achieve synchronous rotation of multiple limit seats, which facilitates the spraying of multiple fire extinguishers and improves spraying efficiency.

[0004] While the aforementioned patent allows for simultaneous spraying of multiple fire extinguisher cylinders, thus improving efficiency compared to manual spraying, the bottom of the fire extinguisher cylinder is placed within a limiting seat. During the spraying process, the bottom of the fire extinguisher cylinder cannot be sprayed due to the obstruction of the limiting seat, requiring separate spraying of the bottom of the fire extinguisher later. This not only makes the operation cumbersome but also reduces efficiency compared to automated spraying. Utility Model Content

[0005] The purpose of this invention is to provide a fire extinguisher cylinder spraying device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fire extinguisher cylinder spraying device includes a housing and a spraying mechanism. The housing is detachably connected to a pull-out plate. The top surface of the pull-out plate is provided with rotating mechanisms at equal intervals for fixing the fire extinguisher cylinder and driving the cylinder to rotate.

[0008] The rotating mechanism includes a round rod that rotates through the pull-out plate, and a cavity is provided at the top of the round rod, with an inner support assembly inside the cavity.

[0009] Furthermore, the outer wall of the round rod is provided with multiple sliding holes at equal angles through the top. The inner support assembly includes two symmetrical sliders that slide within the cavity. Multiple abutments are provided at equal angles between the two sliders. Multiple fixing seats are fixedly connected at equal angles to the outer wall of the slider. Fixing seats are fixedly connected to both ends of the side of the abutments. A connecting rod is fixedly connected between the fixing seats and the fixing seats at corresponding positions.

[0010] Furthermore, the cavity is rotatably connected to two sliders at corresponding positions via a bidirectional screw, and the bottom end of the bidirectional screw is fixedly connected to a connecting rod that rotates through the bottom end of the round rod.

[0011] Furthermore, a rubber pad is fixedly connected to the side of the abutment plate.

[0012] Furthermore, a synchronous double-groove pulley is fixedly connected to the bottom of the outer wall of the round rod, and two adjacent synchronous double-groove pulleys are connected by a synchronous belt drive.

[0013] Furthermore, a motor is fixedly connected to the bottom surface of the pull-out plate, and a gear is fixedly connected to the output end of the motor. A gear two that meshes with gear one is fixedly connected to the bottom end of the outer wall of the round rod near the gear.

[0014] Furthermore, two symmetrical limiting plates are fixedly connected to the two opposite sides of the interior of the box, and sealing gaskets are fixedly connected to both ends of the pull-out plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By inverting the fire extinguisher cylinder onto a round rod and fixing the cylinder with an internal support assembly, the outer surface of the cylinder is fully exposed. Then, by rotating the round rod, the cylinder rotates, allowing the outer wall of the cylinder to be sprayed more evenly. This eliminates the need for separate spraying of any missed parts of the cylinder later, thereby improving the efficiency of fire extinguisher cylinder spraying. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 - Figure 4 In this embodiment of the utility model, a fire extinguisher cylinder spraying device includes a housing 1 and a spraying mechanism 3. The spraying mechanism 3 can move up and down inside the housing 1. A pull-out plate 11 is detachably connected inside the housing 1. A rotating mechanism 2 for fixing the fire extinguisher cylinder and driving the cylinder to rotate is provided at equal intervals on the top surface of the pull-out plate 11. The rotating mechanism 2 includes a round rod 21 that rotates through the pull-out plate 11. A cavity is opened at the top of the round rod 21, and an inner support assembly is provided inside the cavity.

[0024] Specifically, firstly, the spraying mechanism 3 is connected to an external pumping device (the paint is pumped into the spraying mechanism 3 and then sprayed out; this is a common technique in the prior art and will not be elaborated upon here). Then, the pull-out plate 11 is pulled out from the housing 1, and the fire extinguisher cylinder is inserted with its nozzle facing down onto the corresponding rod 21. The cylinder is then fixed by the internal support assembly. After the cylinder is fixed onto each rod 21, the pull-out plate 11 is inserted into the housing 1, and the rotation of the rod 21 causes the corresponding cylinder to rotate. Simultaneously, the coating is sprayed onto the outer wall of the fire extinguisher cylinder by the spraying mechanism 3. During the spraying process, hot air can be introduced into the housing 1 through external drying equipment to cure the coating on the outside of the cylinder. This device exposes the outer side of the cylinder by inverting the fire extinguisher cylinder onto the round rod 21 and fixing the cylinder with the internal support assembly. Then, the rotation of the round rod 21 drives the cylinder to rotate, so that the outer wall of the cylinder can be sprayed more evenly. There is no need to spray the missed parts of the cylinder separately afterward, thereby improving the efficiency of fire extinguisher cylinder spraying.

[0025] Example 1

[0026] like Figure 3 and Figure 4As shown, in this embodiment, the top of the outer wall of the round rod 21 is provided with multiple sliding holes 22 through it at equal angles. The inner support assembly includes two symmetrical sliders 23 that slide in the cavity. Multiple abutments 24 are provided between the two sliders 23 at equal angles. Multiple fixing seats 25 are fixedly connected to the outer wall of the sliders 23 at equal angles. Fixing seats 26 are fixedly connected to both ends of the side of the abutment 24. A connecting rod 27 is fixedly connected between the fixing seats 25 and the fixing seats 26 at the corresponding positions. A bidirectional screw 28 is rotatably connected between the two ends of the cavity and is screwed through to the two sliders 23 at the corresponding positions. A connecting rod 29 is fixedly connected to the bottom end of the bidirectional screw 28 and rotates through to the bottom end of the round rod 21. A rubber pad is fixedly connected to the side of the abutment 24.

[0027] In this embodiment, the rotation of the bidirectional screw 28 can bring the two sliders 23 closer together. The two sliders 23 that are close together can unfold the multiple abutments 24 through multiple connecting rods 27 until the multiple abutments 24 are in close contact with the inner wall of the barrel. Since the sides of the abutments 24 are fixedly connected with rubber pads, the friction between the abutments 24 and the barrel can be increased. Therefore, when the round rod 21 rotates, it will drive the multiple abutments 24 at the corresponding positions to rotate, so that the barrel follows the rotation of the round rod 21, making the spraying on the outside of the barrel more uniform.

[0028] Example 2

[0029] like Figure 2 and Figure 3 As shown, in this embodiment, a synchronous double-groove pulley 211 is fixedly connected to the bottom of the outer wall of the round rod 21. Two adjacent synchronous double-groove pulleys 211 are connected by a synchronous belt drive. A motor 12 is fixedly connected to the bottom surface of the pull-out plate 11. A gear 13 is fixedly connected to the output end of the motor 12. A gear 2 that meshes with the gear 13 is fixedly connected to the bottom of the outer wall of the round rod 21 near the gear 13.

[0030] In this embodiment, the motor 12 drives the gear 13 to rotate, and the rotation of the gear 2 causes the corresponding round rod 21 to rotate. Since two adjacent round rods 21 are connected by a synchronous double-groove pulley 211 and a synchronous belt, the rotating round rod 21 can drive multiple other round rods 21 to rotate simultaneously.

[0031] Example 3

[0032] like Figure 2 As shown, in this embodiment, two symmetrical upper and lower limiting plates 14 are fixedly connected to the two opposite sides of the inside of the box 1, and sealing gaskets are fixedly connected to both ends of the pull-out plate 11.

[0033] In this embodiment, the detachable connection between the pull-out plate 11 and the box 1 facilitates the staff to take the fire extinguisher cylinder and makes it convenient for the staff to inspect and maintain the rotating mechanism 2 later.
