Description

Technical Field

[0001] This utility model relates to the field of production and processing, and in particular to a conveying device for spray coating production. Background Technology

[0002] Spray coating is a surface treatment process that refers to the process of using spraying equipment to uniformly cover the surface of a workpiece with paint, powder or other coating materials in the form of a mist, forming a coating with protective, decorative or special functions.

[0003] The conveying device in the spraying production line is the core equipment for realizing the automated transfer of workpieces. It is usually linked with the spraying equipment to realize the automatic feeding, transfer, spraying and unloading of workpieces, reduce manual intervention and improve production efficiency.

[0004] Currently, to ensure that the paint can be evenly sprayed on different surfaces of the workpiece during the spraying process, the workpiece is often rotated to ensure that different positions of the workpiece are evenly sprayed. However, in actual use, in order to save time, the workpiece is often placed on the upper surface of the storage plate and fixed by a fixture. Therefore, when the workpiece is rotated, the paint on the surface of the workpiece often comes into contact with the storage plate, which causes the paint to be scratched and affects the spraying effect. To address this problem, a conveying device for spraying production is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a conveying device for spraying production, which aims to improve the problem in the prior art that the paint is easily scratched during the rotation of the workpiece, affecting the spraying effect.

An air bladder is fixedly connected to one end of the clamping plate near the middle of the frame. The interior of the air bladder is connected to the interior of the pressure chamber. The end of the clamping plate away from the air bladder is elastically connected to the inner wall of the mounting frame through an elastic telescopic rod.

[0010] As a further description of the above technical solution:

[0011] The inner wall of the frame is rotatably connected to a rotating shaft, and the outer wall of the rotating shaft is fixedly connected to a pulley. There are two rotating shafts and two pulleys, and the outer walls of the two pulleys are connected by a conveyor belt.

[0012] As a further description of the above technical solution:

[0013] A motor is fixedly connected to the front end of the frame near the left side, and the output shaft of the motor is fixedly connected to the front end of the left rotating shaft.

[0014] As a further description of the above technical solution:

[0015] The mounting bracket is concave in shape, and its front and rear ends are in contact with the front and rear inner walls of the frame.

[0016] As a further description of the above technical solution:

[0017] The rotating sleeve is in the shape of a cylindrical tube, and the outside of the rotating sleeve is provided with annular protrusions.

[0020] As a further description of the above technical solution:

[0021] The movable groove is in the shape of parallel grooves, and the control groove is in the shape of parallel grooves with an inner diameter larger than the inner diameter of the movable groove and an outer diameter smaller than the outer diameter of the movable groove. A notch is provided at the top center of the control groove, and the inner wall of the control groove near the notch is inclined.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by setting gears, trapezoidal blocks, racks, sliding grooves, movable grooves, rotating sleeves, etc., it is ensured that before the workpiece enters the spraying area, it can first move upward through the inclined surface of the trapezoidal block, and then rotate through the combined action of gears and racks. This ensures that when the workpiece enters the spraying area, it can achieve a uniform spraying effect through rotation. At the same time, because it moves upward before rotation, it ensures that it will not contact the top of the mounting frame, thus ensuring that the workpiece and the mounting frame will not scratch each other during the spraying process.

[0024] 2. In this utility model, by setting up a mounting frame, rotating sleeve, sliding rod, air chamber, air control block, clamping plate, and airbag, it is ensured that after the workpiece moves away from the position of the control clamping groove with the mounting frame, the sliding rod and the air control block can contact the inclined position of the control clamping groove to ensure that the clamping plate moves towards the workpiece first. After it can no longer move, the expansion of the airbag fills the gap between the workpiece and the clamping plate, thereby ensuring that the workpiece is well fixed and achieving the effect of preventing the workpiece from falling off during the spraying process.

A rotating shaft 2 is rotatably connected to the inner wall of the frame 1, and a pulley 3 is fixedly connected to the outer wall of the rotating shaft 2. The number of rotating shaft 2 and pulley 3 is set to two, and a conveyor belt 4 is drivenly connected to the outer wall of the two pulleys 3. The conveyor belt 4 is in a taut state.

[0036] Reference Figure 2 , Figure 6 and Figure 7A fixing mechanism 5 is provided on the exterior of the conveyor belt 4 and inside the frame 1. The fixing mechanism 5 includes a mounting frame 51, which is concave in shape, and its front and rear ends are in contact with the inner walls of the front and rear sides of the frame 1. The outer wall of the mounting frame 51 is fixedly connected to the outer wall of the conveyor belt 4. When the conveyor belt 4 moves, the mounting frame 51 moves accordingly. A rotating sleeve 52 is provided inside the mounting frame 51. The rotating sleeve 52 is cylindrical in shape, and its exterior is provided with an annular protrusion. A sliding rod 53 is slidably connected to the inner wall of the rotating sleeve 52. The rotating sleeve 52 is relatively... The sliding direction of the slide bar 53 is back and forth. The inner wall of the slide bar 53 is provided with a pressure chamber 54. The inner wall of the pressure chamber 54 is connected to a control block 55 by a piston. A piston is provided on the outside of the control block 55, and the outer wall of the piston is in contact with the inner wall of the pressure chamber 54. A clamping plate 56 is fixedly connected to the outer wall of the slide bar 53. The inner wall of the mounting frame 51 is magnetically connected to the outer wall of the clamping plate 56. A magnet is provided at the end of the clamping plate 56 near the conveyor belt 4, and a magnet is provided at the end of the mounting frame 51 away from the conveyor belt 4. The magnetic poles of the magnet inside the mounting frame 51 and the magnet inside the clamping plate 56 are opposite at their respective ends.

[0037] Reference Figure 2 , Figure 6 and Figure 7 An airbag 57 is fixedly connected to one end of the clamping plate 56 near the middle of the frame 1. The airbag 57 is made of rubber and is in a contracted state when not subjected to external force. The airbag 57 has the ability to recover from deformation. The interior of the airbag 57 is connected to the interior of the air pressure chamber 54. When the air pressure inside the air pressure chamber 54 increases, the gas inside the air pressure chamber 54 can enter the interior of the airbag 57. The end of the clamping plate 56 away from the airbag 57 is elastically connected to the inner wall of the mounting frame 51 through an elastic telescopic rod 58. The elastic telescopic rod 58 is composed of an external telescopic tube and an internal tension spring. One end of the elastic telescopic rod 58 is fixedly connected to the end of the clamping plate 56 away from the airbag 57, and the other end of the elastic telescopic rod 58 is slidably connected to the inner wall of the mounting frame 51. The sliding direction of the elastic telescopic rod 58 relative to the interior of the mounting frame 51 is up and down.

[0038] Reference Figure 2 , Figure 3 and Figure 5 The inner wall of the frame 1 is provided with a movable groove 6, which is in the shape of parallel grooves. On the inner wall of the frame 1 on the side of the movable groove 6 away from the middle of the frame 1, a control groove 7 is provided. The control groove 7 is in the shape of parallel grooves with an inner diameter larger than the inner diameter of the movable groove 6 and an outer diameter smaller than the outer diameter of the movable groove 6. A notch is provided at the top center of the control groove 7, and the inner wall of the control groove 7 near the notch is set to be inclined.

[0039] Reference Figure 3 , Figure 4 and Figure 7A rotating assembly 8 is provided on the exterior of the internal rotating sleeve 52 of the frame 1. The rotating assembly 8 includes a gear 81, the inner wall of which penetrates and is fixedly connected to the outer wall of the rotating sleeve 52. A trapezoidal block 82 is fixedly connected to the inner wall of the movable groove 6. The trapezoidal block 82 is an isosceles trapezoid. A rack 83 is fixedly connected to the inner wall of the movable groove 6 above the trapezoidal block 82. When the outer wall of the rotating sleeve 52 contacts the top of the trapezoidal block 82, the gear 81 meshes with the rack 83. A sliding groove 84 is provided on the inner wall of the mounting frame 51. The shape is a straight groove, and the width of the sliding groove 84 matches the outer diameter of the rotating sleeve 52. The mounting bracket 51 is provided with a straight groove with a width greater than that of the sliding groove 84 in the middle area of ​​the sliding groove 84. The annular protrusion on the outside of the rotating sleeve 52 is located inside the groove. The groove ensures that the rotating sleeve 52 can move up and down and rotate around its axis, but cannot move in the front and back direction. The front end of the frame 1 near the left side is fixedly connected to the motor 9. The output shaft of the motor 9 is fixedly connected to the front end of the left rotating shaft 2.

[0040] Working principle: When in use, the operator places the workpiece that needs to be coated with paint inside the mounting bracket 51 on the left side of the equipment.

[0041] When the equipment is started, the output shaft of the motor 9 can drive the left rotating shaft 2 to rotate, which in turn drives the left pulley 3 to rotate, thus causing the conveyor belt 4 to move. Therefore, during the movement of the conveyor belt 4, it drives the mounting frame 51 and its internal workpiece to move synchronously from left to right.

[0042] When the mounting frame 51 moves to a position close to the edge of the control clamp groove 7, the outer wall of the control block 55 contacts the inclined surface of the control clamp groove 7. During the movement, due to the thrust of the inclined surface of the control clamp groove 7 as it moves with the mounting frame 51, it moves towards the side closer to the middle of the frame 1.

[0043] Since the airbag 57 has deformation recovery capability, and the air control block 55 moves relative to the slide bar 53, the gas inside the air chamber 54 will be pushed into the airbag 57, causing the airbag 57 to inflate. Therefore, it is necessary to overcome the force that causes the airbag 57 to deform. However, when the air control block 55 moves, it pushes the slide bar 53 with gas, so that it moves synchronously with the air control block 55, and it is not necessary to overcome the deformation force of the airbag 57.

[0044] Since the clamping plate 56 is not in contact with the outer wall of the workpiece in the initial state, the slide bar 53 and the air control block 55 move synchronously towards the workpiece at the beginning. When the air bag 57 contacts the workpiece, that is, after the clamping plate 56 contacts the workpiece through the air bag 57, since there is no room for the clamping plate 56 to move, the air control block 55 moves relative to the slide bar 53. Therefore, the area of ​​the air control block 55 entering the air pressure chamber 54 increases, so the gas inside the air pressure chamber 54 is forced into the air bag 57, thereby causing the air bag 57 to expand. This ensures that the gap between the clamping plate 56 and the surface of the workpiece is filled, and that the front and rear ends of the workpiece can be relatively fixed by the resistance of the clamping plate 56.

[0045] After the workpiece is completely fixed, the mounting bracket 51 continues to move to the right and moves until the outer wall of the rotating sleeve 52 contacts the inclined surface of the trapezoidal block 82. At this time, the rotating sleeve 52 moves upward while moving to the right.

[0046] When the rotating sleeve 52 moves to its highest point, the gear 81 is just engaged with the rack 83. As it continues to move, the gear 81 is forced to rotate because its teeth are obstructed by the teeth of the rack 83, which drives the rotating sleeve 52 to rotate. The rotating sleeve 52 then drives the slide rod 53 to rotate synchronously with it, thereby causing the clamping plate 56 and the workpiece to rotate.

[0047] Since the workpiece moves upward before rotating, it will not come into contact with the surface of the mounting bracket 51 during the rotation process. This ensures that when the workpiece enters the spraying area, it can be rotated to ensure that its surface is sprayed evenly and that the paint is not scratched.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
