Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, and in particular to a paint spraying device. Background Technology

[0002] Paint spraying equipment is a specialized device used to evenly and efficiently coat paint onto the surface of workpieces. It is widely used in various fields such as automotive, aerospace, shipbuilding, architectural decoration, and furniture manufacturing. Paints often contain volatile organic compounds (VOCs), heavy metals (such as lead and chromium), and toxic solvents (such as toluene and xylene). These substances form aerosols during the spraying process, which, if inhaled by workers, may cause respiratory diseases, neurological damage, or even cancer. By using paint spraying equipment to keep the spray nozzle away from workers, a physical barrier is formed, reducing the chance of workers directly contacting paint droplets and harmful gases, thereby lowering health risks. Patent application number 202422074908.9 discloses a manual spraying arm, including a walking base, a support arm, a telescopic arm, a telescopic drive assembly, and a painting assembly. The support arm is rotatably connected to the walking base, and its length is adjustable. The telescopic arm is movably connected to the end of the support arm away from the walking base, and is telescopic. The telescopic drive assembly is connected to the telescopic arm and is used to drive the telescopic arm to extend and retract. The painting assembly includes a paint sprayer, a first pipe, a paint spray switch, a second pipe, and a paint spray head connected in sequence. The paint sprayer is mounted on the walking base, the paint spray switch is mounted on one end of the telescopic arm, and the paint spray head is mounted on the other end of the telescopic arm. In this manual spraying arm, a handwheel needs to be operated to drive a screw to rotate, which in turn drives the telescopic arm to extend and retract. The extension and retraction adjustment efficiency is low, and the position of the screw away from the handwheel is fixed. When the telescopic arm retracts, the paint spray head easily sprays paint onto the screw. Utility Model Content

[0033] Please see Figure 1 , Figure 2 and Figure 3A paint spraying device according to an embodiment of the present invention includes a walking base 100, a support arm 200, and a telescopic arm 300. The walking base 100 includes a support seat 110, a walking wheel 130, and a handle 120. The walking wheel 130 is located below the support seat 110, and the handle 120 is mounted on the support seat 110, facilitating the movement of the support seat 110. The support arm 200 is mounted on the walking base 100, and its length is adjustable. The telescopic arm 300 is movably connected at its middle section to the end of the support arm 200 away from the walking base 100. The telescopic arm 300 includes a first connecting rod 310, a second connecting rod 320, and at least one X-shaped hinge frame. One end of the first connecting rod 310 is hinged to the X-shaped hinge frame, one end of the second connecting rod 320 is hinged to the X-shaped hinge frame, and the other end of the first connecting rod 310 is hinged to the other end of the second connecting rod 320. The painting assembly 400 includes a paint sprayer 410, a first pipe 420, a paint spray switch 430, a second pipe 440, and a paint spray head 450 connected in sequence. The paint sprayer 410 is mounted on the traveling base 100, the paint spray switch 430 is mounted on one end of the telescopic arm 300, and the paint spray head 450 is mounted on the other end of the telescopic arm 300.

[0034] The operator can operate the paint spray switch 430 to transfer the paint in the paint sprayer 410 to the spray head 450 for spraying through the first pipe 420 and the second pipe 440. By holding the two ends of the X-shaped hinge frame, the operator can control the two ends of the X-shaped hinge frame to move closer or further apart, which has high telescopic adjustment efficiency. This drives the hinge point of the first link 310 and the second link 320 to extend and retract back and forth, thereby driving the spray head 450 to extend and retract back and forth. When the telescopic arm 300 retracts, the end of the telescopic arm 300 located at the spray head 450 retracts synchronously, making it less likely for the spray head 450 to splash paint onto the telescopic arm 300. The operator can operate the telescopic arm 300 to swing left and right on the support arm 200, thereby driving the spray head 450 to swing left and right. This allows for left or right rotation spraying, spraying from far to near or from near to far, with a wide spraying range and strong applicability.

[0035] In some embodiments, see Figure 1 , Figure 2 and Figure 3The X-shaped articulated frame includes a third link 331 and a fourth link 332. The middle part of the third link 331 is hinged to the middle part of the fourth link 332. One end of the third link 331 is hinged to one end of the first link 310, and one end of the fourth link 332 is hinged to one end of the second link 320. The middle parts of the third link 331 and the fourth link 332 are movably connected to the end of the support arm 200 away from the walking base 100. The hinge between the middle parts of the third link 331 and the fourth link 332 forms an X-shaped structure. By holding one end of the third link 331 and one end of the fourth link 332 and moving them closer together, the telescopic arm 300 can be extended as a whole; by moving the end of the third link 331 away from the end of the fourth link 332, the telescopic arm 300 can be shortened as a whole, resulting in high efficiency in telescopic adjustment.

[0036] In some embodiments, see Figure 1 , Figure 2 and Figure 3 A first handle 3311 is provided at the end of the third link 331 away from the first link 310, and a second handle 3321 is provided at the end of the fourth link 332 away from the second link 320. The paint spray switch 430 is detachably connected to the first handle 3311. The paint spray switch 430 is secured to the first handle 3311 with a strap. While holding the first handle 3311, the paint spray switch 430 can be held, making it convenient to control the painting work while operating the telescopic arm 300.

[0037] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The angle between the axis of the first handle 3311 and the axis of the third link 331 is an obtuse angle, and the angle between the axis of the second handle 3321 and the axis of the fourth link 332 is also an obtuse angle. The first handle 3311 extends downward at an angle along one end of the third link 331, and the second handle 3321 extends downward at an angle along one end of the fourth link 332, making it convenient for the hand to hold and press the handles to lift the first link 310 and the second link 320 upward.

[0038] In some embodiments, see Figure 1 , Figure 2 and Figure 3A support bolt 210 is provided above the support arm 200. A first connecting hole is provided in the middle of the third connecting rod 331, and a second connecting hole is provided in the middle of the fourth connecting rod 332. The support bolt 210 passes through the first and second connecting holes. The diameter of the first connecting hole is larger than the diameter of the support bolt 210, and the diameter of the second connecting hole is larger than the diameter of the support bolt 210. The upper end of the first connecting hole is chamfered, and the lower end of the second connecting hole is chamfered. The X-shaped hinge frame can rotate around the support bolt 210. The X-shaped hinge frame can swing up and down with the support bolt 210 as the fulcrum, with a high degree of freedom, which makes the spraying range of the paint head 450 wider.

[0039] In some embodiments, see Figure 1 , Figure 2 and Figure 3 A first washer 211 and a second washer 212 are fitted onto the support bolt 210. The third link 331 and the fourth link 332 are located between the first washer 211 and the second washer 212. A support nut 213 is connected to the end of the support bolt 210 away from the walking base 100. The first washer 211 is located below the third link 331 and the fourth link 332, and the second washer 212 is located above the third link 331 and the fourth link 332. The first washer 211 can provide support for the third link 331 and the fourth link 332, and the second washer 212, together with the support nut 213, can prevent the third link 331 and the fourth link 332 from coming off the support bolt.

[0040] In some embodiments, see Figure 1 , Figure 2 and Figure 3 An arc-shaped plate 3312 is connected to the third link 331. An arc-shaped hole 3313 is provided on the arc-shaped plate 3312, and the center of curvature of the inner wall of the arc-shaped hole 3313 is the hinge point between the third link 331 and the fourth link 332. A limiting member is connected to the fourth link 332, and the limiting member passes through the arc-shaped hole 3313. By holding the first handle 3311 and the second handle 3321, the first handle 3311 and the second handle 3321 are moved closer or further apart, thus extending or shortening the telescopic arm 300. The arc-shaped plate 3312 and the limiting member limit the range of movement of the first handle 3311 and the second handle 3321, thereby limiting the telescopic range of the telescopic arm 300.

[0041] In some embodiments, see Figure 1 , Figure 2 and Figure 3The limiting component includes a first adjusting bolt 3322, which passes through an arc-shaped hole 3313. An adjusting nut 3323 is threaded onto the first adjusting bolt 3322. An arc-shaped plate 3312 is located between the adjusting nut 3323 and the fourth connecting rod 332. The adjusting nut 3323 is a disc nut for easy operation. When the telescopic arm 300 extends to the specified length, the adjusting nut 3323 can be tightened, preventing the third connecting rod 331 and the fourth connecting rod 332 from continuing to rotate relative to each other, thus keeping the length of the telescopic arm 300 fixed. When it is necessary to adjust the length of the telescopic arm 300, the adjusting nut 3323 is loosened, and the first handle 3311 and the second handle 3321 are grasped, causing the first handle 3311 and the second handle 3321 to move closer or further apart, causing the first adjusting bolt 3322 to slide within the arc-shaped hole 3313.

[0042] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The support arm 200 includes a lower tube 220, an upper rod 230, and a second adjusting bolt 240. The lower end of the upper rod 230 slides through the lower tube 220, and the lower end of the lower tube 220 is mounted on the traveling base 100. A threaded hole is provided on the lower tube 220, connecting to the interior of the lower tube 220. The second adjusting bolt 240 passes through the threaded hole and abuts against the upper rod 230 to restrict its movement. Loosening the second adjusting bolt 240 allows the upper rod 230 to move within the lower tube 220. Tightening the second adjusting bolt 240 fixes the upper rod 230 in place, thus fixing the position of the upper rod 230 and fixing the height of the support arm 200. The second adjusting bolt 240 can be a disc bolt for ease of operation.

[0043] In some embodiments, see Figure 1 , Figure 2 and Figure 3 Multiple limiting grooves 231 are provided at intervals along the axial direction of the upper rod 230, which are used for the second adjusting bolt 240 to extend into. After adjusting the upper rod 230 to the preset height, the second adjusting bolt 240 is tightened so that the second adjusting bolt 240 extends into one of the limiting grooves 231. The inner wall of the limiting groove 231 abuts against the second adjusting bolt 240, so that the upper rod 230 cannot move up and down relative to the lower tube 220. The upper rod 230 can provide stable support for the telescopic arm 300.
