Abstract
Description
Technical Field
[0001] This utility model relates to the field of spraying technology, and in particular to a spraying device that facilitates painting. Background Technology
[0002] Polyurea is an elastomer material formed by the reaction of isocyanate components and amino compound components. It has a high melting point, high toughness, and good heat resistance, dyeability, and corrosion resistance. It is widely used in many fields. After spraying a single-component polyurea onto the surface of parts, it can effectively improve the performance of the parts in various aspects. The spraying is carried out by spray gun or disc atomizer, which disperses the polyurea into uniform and fine droplets with the help of pressure or centrifugal force. The coating method can be divided into air spraying, airless spraying, electrostatic spraying, and various derivatives of the above basic spraying forms. During the workpiece processing, a protective layer or color layer is formed by spraying.
[0003] Existing spraying equipment used for polyurea spraying typically requires comprehensive spraying. This process involves spraying one side first, then flipping the device to spray the other side, or moving the spray gun, all of which require manual operation, making it time-consuming and labor-intensive. Furthermore, to allow the spray gun to move freely, the feed tube needs to be extended, resulting in a longer paint path. This makes the paint prone to condensation and blockage inside the feed tube due to cooling. Utility Model Content
[0004] In view of this, the present invention provides a spraying device that facilitates painting, so as to solve the above-mentioned technical problems.
[0005] A painting device for easy spraying includes an overhead crane, an automatic telescopic device mounted on the overhead crane, and a spray gun assembly mounted on the automatic telescopic device. The overhead crane includes a bridge frame, a crossbeam mounted on the bridge frame, and a crane car mounted on the crossbeam. The bridge frame includes two support frames and two track beams mounted on the support frames. The crane car is mounted on the crossbeam and moves in a direction perpendicular to the track extension of the track beams via a moving mechanism. The automatic telescopic device is mounted on the crane car. The automatic telescopic device includes a housing and a traction rope disposed within the housing. A spiral spring connected to the traction rope is disposed within the housing. The traction rope is coiled within the housing. The elastic coefficient of the spiral spring within the housing is greater than the mass of the spray gun assembly. The spray gun assembly includes a spray gun and a feed tube connected to the spray gun. The spray gun is fixed to the free end of the traction rope. A heating element, which is a heating rod or a heating wire, is disposed on the outer wall of the feed tube.
[0006] Furthermore, the two support frames are spaced apart from each other, and the two track beams are fixed at both ends to the two support frames respectively, and the two track beams are parallel to each other and spaced apart.

[0010] Furthermore, a positioning device is also provided at the outlet of the device housing.
[0011] Furthermore, the moving mechanism is a lead screw or a slide rail structure driven by a motor.
[0012] Compared with existing technologies, the painting device provided by this utility model, through the installation of the overhead crane, forms a dual-axis moving mechanism that drives the spray gun assembly to move forward, backward, left, and right. Furthermore, the automatic telescopic device allows for rapid adjustment of the spray gun assembly's height, making operation convenient and saving time and labor during manual painting operations, thus improving work efficiency.

[0014] Figure 2 for Figure 1 A schematic diagram of the automatic telescopic device and spray gun assembly of a convenient painting spraying device. Detailed Implementation
[0015] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.
[0016] like Figures 1 to 2The diagram shows a structural schematic of the painting device for easy painting provided by this utility model. The painting device includes a crane 10, an automatic telescopic device 20 mounted on the crane 10, and a spray gun assembly 30 mounted on the automatic telescopic device 20. It is conceivable that the painting device also includes other functional modules such as an air supply device for the spray gun, a material supply device for the spray gun, etc., which are technologies well known to those skilled in the art and will not be described in detail here.
[0017] The overhead crane 10 includes a bridge frame 11, a crossbeam 12 mounted on the bridge frame 11, and a crane 13 mounted on the crossbeam 12.
[0018] The cable tray 11 includes two support frames 111 and two track beams 112 mounted on the support frames 11.
[0019] The support frame 111 can be a steel frame structure. Two support frames 111 are spaced apart from each other. The height and spacing of the support frames 111 are set according to the actual production needs to serve as the supporting foundation for the entire equipment.
[0020] Each of the track beams 112 is fixed at both ends to one of the two support frames 111. The two track beams 112 are parallel to each other and spaced apart to accommodate the crossbeam 12. Each of the two track beams 112 is provided with a slide rail structure, including a slide rail extending along the length of the track beam 112 and multiple sliders disposed on the slide rail. This slide rail structure is a common technology in the field of mechanical manufacturing, and therefore will only be briefly described here.
[0021] The crossbeam 12 is vertically connected to both of the two track beams 112. The two ends of the crossbeam 12 are respectively fixed to the sliders of the two track beams 112. The crossbeam 12 is driven to reciprocate along the slide rail by a drive structure. The drive structure can be a motor, a drag chain, or other equipment. For example, in one embodiment of this application, a linear rack is provided on one side of the slide rail of the track beam 112, and a motor-driven gear is fixed on the crossbeam 12. The gear meshes with the rack, so that when the gear rotates, it will drive the crossbeam 12 to move along the length of the track beam 112.
[0022] The crane trolley 13 is mounted on the crossbeam 12 and moves in a direction perpendicular to the track extension of the rail beam 112 via a moving mechanism. This moving mechanism can be a lead screw or a slide rail structure driven by a motor; no specific limitation is made here. The movement of the crossbeam 12 and the crane trolley 13 achieves the positional movement of the spray gun assembly 30 in a dual-axis direction.
[0023] The automatic telescopic device 20 is mounted on the crane 13 to control the vertical movement of the spray gun assembly 30 in the height direction. The automatic telescopic device 20 includes a housing 21 and a traction rope 22 disposed within the housing 21.
[0024] A spiral spring connected to the traction rope 22 is installed inside the device housing 21. The traction rope 22 is coiled inside the device housing 21. When the traction rope 22 is pulled out of the device housing 21 by an external force, the spiral spring is compressed, thereby forming a force generated by elastic deformation. When the external force disappears, the spring rebounds, causing the traction rope 22 to retract. Correspondingly, a positioning device is also provided at the outlet of the device housing 21. When the positioning button of the positioning device is pressed, the positioning device locks the traction rope 22, preventing it from being pulled out and retracted. The above-mentioned automatic telescopic device 20, spiral spring, positioning device, and other structures and connection methods are existing technologies used in products such as measuring tapes and automatic traction ropes. Therefore, only a brief description is given here, without detailed explanation and illustration. In this embodiment, the elastic coefficient of the spiral spring inside the device housing 21 is greater than the mass of the spray gun assembly 30, thereby allowing the spray gun assembly 30 to rise without external force.
[0025] The spray gun assembly 30 includes a spray gun 31 and a feed pipe 32 connected to the spray gun 31.
[0026] The spray gun 31 is fixed to the free end of the traction rope 22. A spray gun is a device that uses the rapid release of liquid or compressed air as power; it is a common technology widely used in the field of spraying and should be well known to those skilled in the art, therefore only a brief description is given here.
[0027] The feed pipe 32 connects the spray gun 31 and the feed assembly for transporting the paint. A heating element, which can be a heating rod or an electric heating wire, is provided on the outer wall of the feed pipe 32 to heat the paint in the pipe and prevent the paint from accumulating and clogging the pipe due to temperature drop.
[0028] In use, the operator moves the crane 13 to the upper part in front of the product to be sprayed, and pulls the spray gun 31 down to a position that is convenient for spraying. The operator presses the positioning button to fix the position of the spray gun 31 and performs the spraying operation. After the spraying is completed, the positioning button is released, so that the spray gun 31 is pulled and lifted by the traction rope 22 without external force.
[0029] Compared with existing technologies, the painting device provided by this utility model, through the installation of the overhead crane 10, forms a dual-axis moving mechanism that drives the spray gun assembly 30 to move back, forth, left, and right. Furthermore, the automatic telescopic device 20 allows for rapid adjustment of the height of the spray gun assembly 30, making operation convenient and saving time and effort during manual painting operations, thus improving work efficiency. By installing a heating component on the feed pipe 32, the paint inside the feed pipe 32 can be heated, preventing paint from solidifying and clogging the pipe. The device has a simple structure, is easy to use, and effectively solves problems encountered in actual production.
[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
