Description

Technical Field

[0001] The utility model relates to the technical field of composite materials, in particular to a composite material spraying device. Background Art

[0002] Composite materials are composed of two or more materials with different properties, which are combined into materials with new properties on a macro scale through physical or chemical methods. The various materials complement each other in terms of performance, producing a synergistic effect, making the comprehensive performance of the composite material better than the original component materials and meeting various requirements. The matrix materials of composite materials are divided into two categories: metal and non-metal. Composite materials are often sprayed on the surface when they are used.

[0003] After searching, a Chinese patent with publication number CN216879936U discloses a composite material spraying device. The utility model sets a rotating mechanism to replace manual flipping. Through the linkage of two pulleys, the material is sprayed while flipping, which ensures uniform spraying thickness and improves work efficiency.

[0004] However, in the above technical solution, the two pulleys are driven by an electric motor to rotate so that the reciprocating screw and the first rotating rod rotate at the same time, so that the composite material rotates when the sprayer is spraying, so that the spraying is more uniform. However, during spraying, the distance between the sprayer and the surface of the composite material is always changing due to the rotation of the composite material. The distance between the two is closest when the composite material is perpendicular to the ground. At this time, the spraying of the sprayer is likely to cause excessive spraying per unit time, resulting in excessive thickness of the sprayed material, and prone to sagging. The sprayed material flows along the surface of the composite material, affecting the quality of the spraying and causing waste of the sprayed material. In addition, the patent clamps and fixes the composite material by a U-shaped second fixed block. The dead angle caused by clamping is large, requiring manual secondary spraying, which increases the work steps of the workers. Utility Model Content

[0005] The utility model aims to provide a composite material spraying device in view of the problems existing in the background technology.

[0006] The technical solution of the utility model is as follows: a composite material spraying device comprises a spray box, an outer wall of which is rotatably connected to a box door, and a base is connected to the bottom of the spray box; a spray assembly, which is arranged in the spray box and can move back and forth horizontally in the spray box; a clamping assembly, which is symmetrically arranged at both ends of the spray box and is used to clamp the workpiece between the clamping assemblies; and a flipping assembly, which is connected to the clamping assembly and can drive the clamping assembly to rotate.

[0007] Preferably, the spray assembly includes an electric motor connected to either side of the outer wall of the spray box; a reciprocating screw, both ends of which are rotatably connected in the spray box, and either end of the reciprocating screw passes through the side wall of the spray box and is transmission-connected to the output end of the motor; a guide rod, which is stacked up and down with the reciprocating screw and arranged in parallel, and both ends of the guide rod are connected to the inner wall of the spray box; a sliding seat, which is threadedly connected to the reciprocating screw, and the sliding seat is provided with a through hole for sliding connection with the guide rod; a sprayer, which is connected to the sliding seat, and the sprayer will spray onto the workpiece on the clamping assembly when in use.

[0009] Preferably, the clamping assembly includes a coaxial bidirectional screw, which is rotatably connected in a sliding groove opened on one side of the rotating plate close to each other, and either end of the coaxial bidirectional screw passes through the rotating plate and is connected to an adjustment handle; a clamping block, which is threadedly connected to the coaxial bidirectional screw, and the clamping block is slidably connected to the sliding groove; a limit assembly, which is arranged in the clamping block, and when the limit assembly is in use, the limit assembly can prevent the workpiece from slipping off the clamping block.

[0010] Preferably, the limit assembly includes a moving block, which is slidably connected in an upper and lower stacked moving groove opened on the clamping block, and a groove is opened on the side of the moving blocks away from each other on the two clamping blocks of the moving block; an elastic member, whose two ends are respectively connected to the moving block and the moving groove; a moving rod, which is slidably connected in a through hole opened on the clamping block, and a limiting ball is connected to the middle position of the moving rod, and the limiting ball is slidably connected to the groove on the moving block.

[0011] Preferably, the clamping blocks are all L-shaped, and when the clamping blocks move closer to each other, they can form a U-shaped clamping frame.

[0012] Preferably, an observation window is provided on the box door.

[0013] Compared with the prior art, the above technical solution of the utility model has the following beneficial technical effects:

[0014] The utility model can maintain the spraying thickness of the composite material surface and reduce the spraying dead angle caused by clamping. The composite material between the clamping components is sprayed by reciprocating movement of the spraying component arranged in the spray box. After spraying on one side of the composite material is completed, the composite material can be flipped by driving the flipping component to spray on the other side. During spraying, the distance between the composite material and the spraying component is fixed and the spraying component moves at a constant speed to achieve uniform spraying thickness. The clamping component can limit the composite material in both horizontal and vertical directions to prevent the composite material from falling during rotation and spraying. At the same time, the contact area between the clamping component and the two side walls of the composite material is small, which avoids the occurrence of spraying dead angles caused by contact between the two.

DETAILED DESCRIPTION

[0022] Embodiment 1

[0023] like Figure 1-Figure 6As shown, a composite material spraying device proposed by the utility model includes a spray box 1, a box door 2, a base 3, a spraying assembly, a clamping assembly and a flipping assembly. The spray box 1 is connected to the box door 2 by a hinge, and the base 3 connected to the bottom of the spray box 1 can increase the contact area with the ground to prevent shaking. The spraying assembly on the top of the spray box 1 can reciprocate horizontally along the spray box 1 in a working state, so as to spray the material evenly on the surface of the composite material. After the spraying of one side of the composite material is completed, the clamping assembly and the composite material are flipped 180 degrees by the flipping assembly, and the other side of the composite material is sprayed by the spraying assembly. During spraying, the composite material and the spraying assembly always maintain a fixed distance to prevent uneven spraying. The clamping assembly on the flipping assembly can clamp and fix the composite material, and at the same time, the contact area between the clamping assembly and the composite material is small, which reduces the spraying dead angle during spraying.

[0024] In an optional embodiment, an observation window 21 is provided on the box door 2. Through the observation window 21, the working state of the spraying assembly can be observed when the spraying assembly is working to prevent uneven spraying or unstable clamping.

When the reciprocating screw 5 rotates, the sliding seat 7 can reciprocate along the axis of the reciprocating screw 5, and the sprayer 8 under the sliding seat 7 reciprocates to spray the surface of the composite material. The guide rod 6 can prevent the sliding seat 7 from rotating synchronously when the reciprocating screw 5 rotates.

[0027] The flipping assembly includes a support plate 9, a stepper motor 10 and a rotating plate 11. The support plate 9 is symmetrically arranged on the two side walls of the spray box 1, the stepper motor 10 is connected to the support plate 9, and the output end of the stepper motor 10 is connected to the rotating plate 11. The rotating plate 11 is used to set a clamping assembly; after the stepper motor 10 is started, its output end will rotate and drive the rotating plate 11 to flip 180 degrees. The clamping assembly on the rotating plate 11 will drive the composite material to rotate so that the two side walls of the composite material are successively close to the spraying assembly for spraying.

[0028] Embodiment 3

[0029] like Figure 3-Figure 6 As shown, a composite material spraying device proposed by the utility model, compared with the second embodiment, the detailed structure of the clamping assembly is also recorded in this embodiment, the clamping assembly includes a coaxial bidirectional screw 12, a clamping block 14, an adjusting handle 15 and a limit assembly, two rotating plates 11 are provided with sliding grooves 13 on one side close to each other, the coaxial bidirectional screw 12 is rotatably connected in the sliding groove 13, either end of the coaxial bidirectional screw 12 passes through the rotating plate 11 and is connected to the adjusting handle 15, the clamping block 14 is threadedly connected to the coaxial bidirectional screw 12 and is slidably connected to the sliding groove 13, and the limit assembly is arranged on the clamping block 14; when the adjusting handle 15 rotates, it can drive the two clamping blocks 14 on the coaxial bidirectional screw 12 to move in opposite directions, and the composite material workpiece is clamped and fixed by the clamping block 14, and the limit assembly arranged on the clamping block 14 can limit the movement of the composite material workpiece in the vertical direction.

[0030] In an optional embodiment, the clamping blocks 14 are all L-shaped, and when the clamping blocks 14 move closer to each other, they can form a U-shaped clamping frame. The L-shaped clamping blocks 14 can have more contact area with the composite material to increase the friction between the two.

[0031] The limiting assembly includes a moving block 16, an elastic member 18, a moving rod 19 and a limiting ball 20. The side of the clamping block 14 away from the rotating plate 11 is used to open a moving groove 17 stacked up and down. The moving block 16 is slidably connected in the moving groove 17. The elastic member 18 is symmetrically arranged at both ends of one side of the moving block 16. The two ends of the elastic member 18 are respectively connected to the inner wall of the moving groove 17 and the moving block 16. The elastic member 18 adopts but is not limited to a spring.

When the limiting ball 20 slides, it enters the groove in the moving block 16 and pushes the moving block 16 to extend a distance from one end of the moving groove 17, so that the clamping block 14 has a certain ability to limit its vertical movement when clamping the composite material in the horizontal direction, preventing the friction between the two from being too small and causing it to tilt and fall.

[0032] In summary, when the utility model is used, the cabinet door is opened to prevent the composite material from being placed in the spray box 1, and the adjusting handle 15 is turned to rotate so that the two clamping blocks 14 on the coaxial bidirectional screw 12 can be driven to move toward each other, and the clamping blocks 14 clamp and fix the composite material workpiece; at this time, the moving rod 19 in the limiting assembly is in a lower position due to its own weight and the limiting ball 20, and the limiting ball 20 contacts the lower moving block 16 of the two moving blocks 16 to push it to slide out of the moving groove 17, and the moving block 16 stretches the elastic member 18, and the upper moving block 16 is pulled by the elastic member 18 and is in the moving groove 17; the motor 4 is started to drive the reciprocating screw 5 to rotate, and is in a forward and backward position. The sliding seat 7 on the reciprocating screw 5 will reciprocate along the axis of the reciprocating screw 5. When the sliding seat 7 moves, the sprayer 8 below it performs the spraying operation. After the spraying of one side of the composite material is completed, its flipping is controlled by the flipping component, and the stepper motor 10 is started to drive the rotating plate 11 to rotate through the rotation of the output shaft of the stepper motor 10.

One end of the moving rod 19 and the limiting ball 20 move toward the moving groove 17 at the bottom after the flipping. The limiting ball 20 contacts the moving block 16 at the lower position at this time, pushing it to extend the moving rod 19, and the composite material is prevented from falling downward by multiple moving blocks 16.
