An advertisement sign painting device

Abstract

This utility model relates to the field of advertising sign spraying technology, and proposes an advertising sign spraying device, including a processing table. Two sets of sliding plates are slidably mounted on the processing table. Positioning devices are installed on the sliding plates to prevent paint sprayed onto the clamping plate from flowing onto the advertising sign. Limiting devices for clamping the advertising sign are also installed on the sliding plates. This utility model limits the advertising sign using suction cups, then pulls out the insert rod to separate it from the sliding plates, connecting plates, and rotating plates. Under the action of gravity, the connecting plates and rotating plates rotate from a horizontal state to a vertical state, placing them below the advertising sign. During advertising sign spraying, no material remains on the connecting plates and rotating plates, avoiding the situation where material sprayed onto the L-shaped clamping plate flows along the L-shaped clamping plate onto the advertising sign, resulting in poor spraying effect.

Description

Technical Field

[0001] This utility model relates to the field of advertising sign spraying technology, specifically to an advertising sign spraying device. Background Technology

[0002] Signage advertising refers to advertising that uses a logo as its basic image and content. This includes signage advertising on television, on the internet, as well as souvenirs and packaging materials printed with a company's trademark. During the production of advertising signs, a spray coating process is required.

[0003] Patent document CN222568120U discloses a spraying device for advertising sign production, and the protected claim is "to solve the problem that when spraying advertising signs, they need to be clamped and fixed. However, in traditional clamping, the clamping mechanism is located at the top edge of the advertising sign, which causes the spraying mechanism to spray material onto the clamping mechanism, resulting in incomplete spraying of the advertising sign." However, during the use of this device, since the material does not solidify immediately after being sprayed, when the material is sprayed onto the L-shaped clamping plate of the device, the material flows along the L-shaped clamping plate onto the advertising sign, resulting in poor spraying effect and affecting the spraying quality of the advertising sign. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an advertising sign spraying device that solves the problem that the material sprayed onto the L-shaped clamp will flow along the L-shaped clamp onto the advertising sign, resulting in poor spraying effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An advertising sign spraying device includes a processing table, on which two sets of sliding plates are slidably mounted. The sliding plates are equipped with positioning devices to prevent paint sprayed onto clamping plates from flowing onto the billboard. The sliding plates are also equipped with limiting devices for clamping the billboard.

[0007] The positioning device includes a connecting plate rotatably mounted on a sliding plate, a rotating plate rotatably mounted on the connecting plate, and two sets of insert rods inserted into the rotating plate. The sliding plate, connecting plate, and rotating plate are all provided with two sets of openings that cooperate with the insert rods. As the insert rods separate from the sliding plate, connecting plate, and rotating plate, the connecting plate and rotating plate rotate from a horizontal state to a vertical state under the action of gravity.

[0008] Preferably, the positioning device further includes two sets of positioning holes formed on the sliding plate, each set of positioning holes having a positioning block fixedly installed on it, and the positioning block having a limit groove formed on it.

[0009] Preferably, the positioning device further includes a limiting tube slidably mounted on the limiting groove, a suction cup communicating with the limiting tube is fixedly mounted on the limiting tube, and a threaded plug is threadedly connected to the limiting tube.

[0010] Preferably, the limiting device includes a reciprocating lead screw rotatably mounted on the processing table, and two sets of limiting blocks are threadedly connected to the reciprocating lead screw, with two sets of rotating rods rotatably connected to each set of limiting blocks.

[0011] Preferably, the limiting device further includes four sets of sliding grooves formed on the processing table, each set of sliding grooves is fixedly installed with a fixing rod, and two sets of fixing blocks are fixedly installed on the sliding plate and slidably connected to the fixing rods, and the fixing blocks are rotatably connected to the rotating rods.

[0012] Preferably, a motor is fixedly installed on the processing table, and a reciprocating lead screw is fixedly installed at the output end of the motor.

[0013] Preferably, a paint spraying frame is fixedly installed on the processing table, and a spray nozzle is fixedly installed on the paint spraying frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, through the setting of a positioning device, limits the billboard by a suction cup, and then pulls out the insert rod to separate it from the sliding plate, connecting plate and rotating plate. Under the action of gravity, the connecting plate and rotating plate rotate from a horizontal state to a vertical state, so that the connecting plate and rotating plate are located below the billboard. When spraying the billboard, no material will be left on the connecting plate and rotating plate, avoiding the situation where the material sprayed onto the L-shaped clamp will flow along the L-shaped clamp onto the billboard, resulting in poor spraying effect of the equipment.

[0016] 2. This utility model, through the setting of a limiting device, causes the reciprocating screw at the output end to rotate within the limiting block when the motor is started. The two limiting blocks move towards each other along the reciprocating screw. The movement of the limiting blocks drives the rotating rod to move, causing the rotating rod to rotate between the limiting block and the fixed block. The rotating rod drives the sliding plate connected to the fixed block to move, which can clamp and limit billboards of different sizes, avoiding the situation where the billboard tilts or shifts, resulting in substandard spraying.

[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] Example 1

[0026] Reference Figures 1-5 This embodiment proposes an advertising sign spraying device. By setting the positioning device 2, the problem that the material sprayed onto the L-shaped clamp will flow along the L-shaped clamp onto the advertising sign, resulting in poor spraying effect of the equipment is solved. The device includes a processing table 1, on which two sets of sliding plates 11 are slidably installed. The sliding plates 11 are equipped with a positioning device 2 to prevent the paint sprayed onto the clamping plate from flowing onto the advertising sign. The sliding plates 11 are equipped with a limiting device 3 for clamping the advertising sign. A paint spraying frame 5 is fixedly installed on the processing table 1. A spray nozzle 6 is fixedly installed on the paint spraying frame 5. The external paint connected to the paint spraying frame 5 is delivered to the advertising sign through the spray nozzle 6.

[0027] The positioning device 2 includes a connecting plate 201 rotatably mounted on a sliding plate 11, a rotating plate 202 rotatably mounted on the connecting plate 201, and two sets of insert rods 203 inserted into the rotating plate 202. The sliding plate 11, connecting plate 201, and rotating plate 202 each have two sets of openings 204 that cooperate with the insert rods 203. The insert rods 203 pass through the openings 204 sequentially through the rotating plate 202, connecting plate 201, and sliding plate 11, so that the rotating plate 202, connecting plate 201, and sliding plate 11 form a complete flat plate. The positioning device 2 also includes two sets of positioning holes 205 on the sliding plate 11. Each positioning hole 205 has a fixedly mounted positioning block 206. The positioning block 206 has a limiting groove 207. The positioning device 2 also includes a limiting tube 208 slidably mounted on the limiting groove 207. A suction cup 209 communicating with the limiting tube 208 is fixedly mounted on the limiting tube 208. 8 is threaded with a threaded plug 210. When it is necessary to separate the suction cup 209 from the billboard, rotate the threaded plug 210 to separate it from the limiting tube 208, so that the air pressure inside the suction cup 209 is the same as the outside, thereby separating the suction cup 209 from the billboard. After the billboard is initially limited by the limiting device 3, the four limiting tubes 208 are moved upward to adsorb the suction cup 209 onto the billboard, which can limit the billboard. Pull out the insertion rod 203 to separate it from the sliding plate 11, the connecting plate 201 and the rotating plate 202. Under the action of gravity, the connecting plate 201 and the rotating plate 202 rotate from the horizontal state to the vertical state, so that the connecting plate 201 and the rotating plate 202 are located below the billboard. When spraying the billboard, no material will be left on the connecting plate 201 and the rotating plate 202, avoiding the situation where the material sprayed onto the L-shaped clamp will flow along the L-shaped clamp onto the billboard, resulting in poor spraying effect of the equipment.

[0028] Example 2

[0029] Based on Embodiment 1, the technical solution proposed in Embodiment 1 is used to solve the problem that the material sprayed onto the L-shaped clamp will flow along the L-shaped clamp onto the advertising signboard, resulting in poor spraying effect of the equipment. When positioning a large advertising signboard, if the advertising signboard is tilted or shifted, the spraying will not be up to standard.

[0030] Reference Figures 1-5The limiting device 3 includes a reciprocating lead screw 301 rotatably mounted on the machining table 1. Two sets of limiting blocks 302 are threaded onto the reciprocating lead screw 301. Each set of limiting blocks 302 is rotatably connected to two sets of rotating rods 303. The limiting device 3 also includes four sets of sliding grooves 304 formed on the machining table 1. Each set of sliding grooves 304 is fixedly mounted with a fixing rod 305. Two sets of fixing blocks 306 are fixedly mounted on the sliding plate 11 and slidably connected to the fixing rods 305. The fixing rods 305 make the moving of the fixing blocks 306 in the sliding grooves 304 more stable, and the fixing blocks 306 are rotatably connected to the rotating rods 303. Next, a motor 4 is fixedly installed on the processing table 1. A reciprocating lead screw 301 is fixedly installed at the output end of the motor 4. When the motor 4 is started, the reciprocating lead screw 301 at the output end rotates within the limit block 302. The two limit blocks 302 move towards each other along the reciprocating lead screw 301. The movement of the limit blocks 302 drives the rotating rod 303 to move, so that the rotating rod 303 rotates with the limit block 302 and the fixed block 306. The rotating rod 303 drives the sliding plate 11 connected to the fixed block 306 to move, which can clamp and limit the billboards of different sizes, avoiding the situation where the billboards tilt and shift, resulting in substandard spraying.

[0031] Working principle: Starting the motor 4 causes the reciprocating screw 301 at the output end to rotate within the limiting block 302. The two limiting blocks 302 move towards each other along the reciprocating screw 301. The movement of the limiting blocks 302 drives the rotating rod 303 to move, causing the rotating rod 303 to rotate between the limiting block 302 and the fixed block 306. The rotating rod 303 drives the sliding plate 11 connected to the fixed block 306 to move, which can clamp and limit billboards of different sizes. Moving the four limiting tubes 208 upwards, the suction cup 209 is attracted to the billboard. The upper part can limit the billboard, pull out the plug 203 to separate it from the sliding plate 11, the connecting plate 201 and the rotating plate 202. Under the action of gravity, the connecting plate 201 and the rotating plate 202 rotate from the horizontal state to the vertical state, so that the connecting plate 201 and the rotating plate 202 are located below the billboard. When the billboard is sprayed, no material will be left on the connecting plate 201 and the rotating plate 202, avoiding the situation where the material sprayed onto the L-shaped clamp will flow along the L-shaped clamp onto the billboard, resulting in poor spraying effect of the equipment.
