Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguisher production, in particular to hot air drying paint spraying equipment. Background Art

[0002] The cylinder of a fire extinguisher is usually made of aluminum alloy or steel. After forming, the cylinder needs to be further processed. First, the cylinder is trimmed and polished to remove burrs and flaws on the surface. Then, the cylinder is hole-machined for installing parts such as valves and nozzles. Finally, the cylinder is cleaned and rust-removed to ensure the cleanliness and smoothness of the cylinder surface. The spraying of the cylinder is to improve its anti-corrosion performance and aesthetics. Before spraying, the cylinder needs to be degreased to ensure the quality of the spraying effect. Then, a special spraying equipment is used to spray the cylinder at multiple angles using the spraying parts, and the cylinder is coated with primer, topcoat and varnish to form a uniform coating. After spraying, the cylinder is dried and cured using hot air generated by the drying parts.

[0003] However, during the spraying process of the cylinder, some of the cylinders are transported by chain conveyors. During the transportation process, the cylinder is prone to shaking. During the spraying and drying operations, the shaking amplitude of the cylinder will increase due to the effect of paint spraying and hot air blowing, affecting the painting and drying effects of the cylinder. Utility Model Content

[0004] The purpose of the utility model is to provide a hot air drying paint spraying equipment to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A hot air drying paint spraying device, comprising:

[0007] The spray booth has spray assemblies on both sides for spraying and washing the fire extinguisher cylinder;

[0008] A drying room, which is provided with a hot air component for hot air drying the cylinder of the fire extinguisher after painting;

[0009] A movable frame, wherein a plurality of positioning mechanisms are movably connected to the inner side of the movable frame;

[0010] Guide rails used in conjunction with the positioning mechanism are symmetrically fixed to the tops of the inner sides of the spraying room and the drying room. The guide rails are rod-shaped structures with both ends tilted upward and a straight middle portion.

[0011] Furthermore, the positioning mechanism includes a top cover and a vertical rod passing through and fixed at the center of the top cover, a screw sleeve for screwing and connecting with the top opening of the fire extinguisher cylinder is fixed on the outside of the vertical rod in the top cover, and an interference component for limiting the fire extinguisher cylinder is arranged on the vertical rod with a through groove in the middle.

[0012] The invention further comprises: the abutting component comprises a sliding rod slidably embedded in the inner side of the vertical rod, a cross rod slidably connected to the vertical rod is fixed at the top end of the sliding rod, and the cross rod abuts against the guide rail to push the sliding rod to move relative to the vertical rod, the bottom end of the vertical rod is rotatably connected to a plurality of V-shaped articulated frames, and one end of the V-shaped articulated frame is rotatably connected to one side of a circular ring sleeved by a sliding platform on the outer side of the vertical rod, the inner side of the circular ring is fixed to the outer side of the sliding rod through an axle rod, an extrusion spring is sleeved on the middle part of the sliding rod, and one end of the extrusion spring is fixed to the outer side of the sliding rod, and the other end is fixed to the vertical rod.

[0013] Preferably, the cross bar is located outside the top cover to ensure that after the guide rail contacts the cross bar, the cross bar can push the slide bar to move downward relative to the vertical bar, thereby pushing the V-shaped hinge frame to expand and contact the inner side of the fire extinguisher cylinder to perform limiting work.

[0014] Preferably: a rubber pad is fixed in the middle of the V-shaped articulated frame. After the V-shaped articulated frame is unfolded, the rubber pad can contact the inner wall of the fire extinguisher cylinder, so as to position it, reduce the probability of uneven painting and drying caused by the shaking of the fire extinguisher cylinder itself during painting or drying, and improve the efficiency of painting and drying.

[0015] Preferably, the outer diameter of the circular ring is smaller than the inner diameter of the screw sleeve, and when the multiple V-shaped hinged frames are in the closed state, they can all be located within the circle where the circular ring is located, thereby ensuring that the V-shaped hinged frames can pass through the top opening of the fire extinguisher cylinder in the closed state.

[0016] Furthermore, guide wheels are fixed at both ends of the cross bar, and the guide wheels are connected to the guide rails in a rolling manner. This can reduce friction after the cross bar contacts the guide rails, ensuring that the ends of the guide rails can normally push the cross bar downward, thereby ensuring normal deployment of the resistance components.

[0017] The invention further comprises: the top end of the vertical rod is in a hook shape.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. Guide rails are arranged on both the spray paint room and the drying room, and then when the mobile frame drives the fire extinguisher cylinder to enter the spray paint room or the inside of the drying room, the guide rails can contact the cross bar. Because the guide rails are arranged as a rod-shaped structure with both ends tilted upward and the middle part straight, the guide rails can be used to push the cross bar down when the fire extinguisher cylinder moves. The cross bar pushes the slide bar to slide downward on the inner side of the vertical bar, and the V-shaped articulated frame is pushed to unfold through the circular ring. After the V-shaped articulated frame is unfolded, the middle part of the V-shaped articulated frame contacts the inner wall of the fire extinguisher cylinder. In this way, the guide rails are used to squeeze the cross bar, and the V-shaped articulated frame contacts the fire extinguisher cylinder to keep the fire extinguisher cylinder stable, thereby improving the efficiency of spraying or drying.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1

[0030] See also Figures 1 to 7 In an embodiment of the utility model, a hot air drying paint spraying device comprises:

[0031] The paint spraying room 100 has paint spraying assemblies 110 for spraying and washing the cylinder of the fire extinguisher arranged on both sides of the interior;

[0032] The drying chamber 200 is provided with a hot air assembly 210 for hot air drying the cylinder of the fire extinguisher after painting;

[0033] A movable frame 300, wherein a plurality of positioning mechanisms 400 are movably connected to the inner side of the movable frame 300;

[0034] The tops of the inner sides of the spray booth 100 and the drying booth 200 are symmetrically fixed with guide rails 500 used in conjunction with the positioning mechanism 400. The guide rails 500 are rod-shaped structures with both ends tilted upward and a straight middle portion.

[0035] In this embodiment, the unpainted fire extinguisher cylinder is connected to the positioning mechanism 400, and then the positioning mechanism 400 and the fire extinguisher cylinder are hung on the movable frame 300, and the movable frame 300 is pushed into the inner side of the paint spraying room 100, and the fire extinguisher cylinder is painted by using the paint spraying assembly 110. After painting, the movable frame 300 is continuously pushed into the inner side of the drying room 200. When the positioning mechanism 400 enters the paint spraying room 100 and the drying room 200, the positioning mechanism 400 cooperates with the guide rail 500 to limit the fire extinguisher cylinder and maintain the stability of the fire extinguisher cylinder. After the hot air drying operation is performed by using the hot air assembly 210, the fire extinguisher cylinder can be moved out.

[0036] The paint spraying assembly 110 in this embodiment can achieve uniform spraying of the fire extinguisher cylinder by adjusting the direction of the paint spraying port. The hot air assembly 210 can generate hot air and can use the hot air to dry the fire extinguisher cylinder after painting. This technology is well known to technicians in this technical field and is a commonly used device in this technical field. It will not be elaborated here.

[0037] like Figure 5-7As shown, in this embodiment, the positioning mechanism 400 includes a top cover 410 and a vertical rod 420 that passes through and is fixed to the center of the top cover 410. A screw sleeve 411 for screwing and connecting with the top opening of the fire extinguisher cylinder is fixed inside the top cover 410 and located on the outside of the vertical rod 420. A resistance component for limiting the fire extinguisher cylinder is provided on the vertical rod 420 with a through groove in the middle. The top end of the vertical rod 420 is in a hook shape. The hook-shaped vertical rod 420 is convenient for connecting with the hook at the top of the mobile frame 300, which is easy to operate. The resistance component includes a slide rod 430 that is slidably embedded and connected to the inner side of the vertical rod 420. The top end of the slide rod 430 is fixed A cross bar 431 is provided which is slidably connected to the vertical bar 420. The cross bar 431 slides inside the through groove. After the cross bar 431 contacts the guide rail 500, it pushes the slide bar 430 to move relative to the vertical bar 420. The bottom end of the vertical bar 420 is rotatably connected to a plurality of V-shaped hinge frames 440, and one end of the V-shaped hinge frame 440 is rotatably connected to one side of a ring 450 which is sleeved on the sliding platform outside the vertical bar 420. The inner side of the ring 450 is fixed to the outer side of the slide bar 430 through an axle rod. An extrusion spring 432 is sleeved on the middle part of the slide bar 430, and one end of the extrusion spring 432 is fixed to the outer side of the slide bar 430, and the other end is fixed to the vertical bar 420.

[0038] In a specific implementation, when the mobile rack 300 is just pushed into the spray painting room 100 or the drying room 200, the horizontally placed cross bar 431 contacts the end of the guide rail 500. When the mobile rack 300 is continuously pushed, the guide rail 500 squeezes the cross bar 431, so that the vertical height of the cross bar 431 decreases. The cross bar 431 pushes the slide bar 430 to slide downward on the inner side of the vertical bar 420. The squeezing spring 432 is squeezed and compressed. When sliding, the V-shaped articulated frame 440 is pushed to unfold through the ring 450. After the V-shaped articulated frame 440 is unfolded, the middle part thereof contacts the fire extinguisher. The inner wall of the cylinder body is squeezed by the guide rail 500, and the V-shaped hinge frame 440 contacts the cylinder body of the fire extinguisher to make the cylinder body of the fire extinguisher remain stable, thereby improving the efficiency of painting. After the cross bar 431 is separated from the guide rail 500, the squeezing spring 432 is reset, pushing the slide bar 430 to slide upward on the inner side of the vertical rod 420, and the circular ring 450 is used to drive the V-shaped hinge frame 440 to close and be stored on the outer side of the vertical rod 420. After the painting and drying are completed, the screw sleeve 411 is separated from the cylinder body of the fire extinguisher, and then the V-shaped hinge frame 440 can be taken out.

[0039] like Figure 5-6 As shown, in this embodiment, the cross bar 431 is located on the outside of the top cover 410, and a rubber pad is fixed in the middle of the V-shaped hinged frame 440 to ensure that after the guide rail 500 contacts the cross bar 431, it can push the slide bar 430 to move downward relative to the vertical bar 420 through the cross bar 431, thereby pushing the V-shaped hinged frame 440 to expand and contact the inner side of the fire extinguisher cylinder to perform limiting work.

[0040] In specific implementation, after the V-shaped articulated frame 440 is unfolded, the rubber pad can be used to contact the inner wall of the fire extinguisher cylinder, so as to position it, reduce the probability of uneven painting and drying caused by the shaking of the fire extinguisher cylinder itself during painting or drying, and improve the efficiency of painting and drying.

[0041] In this embodiment, the outer diameter of the ring 450 is smaller than the inner diameter of the screw sleeve 411. When the multiple V-shaped hinged frames 440 are in the closed state, they can all be located within the circle where the ring 450 is located, thereby ensuring that the V-shaped hinged frames 440 can pass through the top opening of the fire extinguisher cylinder in the closed state.

[0042] Embodiment 2

[0043] On the basis of the first embodiment, in order to compensate for the fact that when the guide rail 500 first contacts the cross bar 431 in the first embodiment, the contact between the two easily causes the shaking of the positioning mechanism 400 and the fire extinguisher cylinder, so as to achieve the effect of stabilizing the fire extinguisher cylinder.

[0044] like Figure 6 As shown, in this embodiment, guide wheels are fixed at both ends of the cross bar 431, and the guide wheels are used to roll in connection with the guide rail 500. This can reduce the friction after the cross bar 431 contacts the guide rail 500, ensuring that the end of the guide rail 500 can normally push the cross bar 431 downward. On the one hand, it ensures the normal deployment of the interference component, and on the other hand, it makes the cross bar 431 stably contact with the guide rail 500, thereby improving the stability of the fire extinguisher cylinder.
