Description

Technical Field

[0001] This utility model relates to the field of workpiece coating technology, specifically a coating flipping mechanism. Background Technology

[0002] Coating is an important part of modern product manufacturing processes. The quality of rust-proof and corrosion-proof coatings is one of the important aspects of overall product quality. The appearance quality of a product not only reflects its protective and decorative performance, but is also an important factor in its value. Coating is a systematic project that includes three basic processes: surface treatment of the object to be coated, coating process, and drying, as well as designing a reasonable coating system, selecting suitable paints, determining good working environment conditions, and carrying out important aspects such as quality, process management, and technical and economic aspects.

[0003] In the existing technology, the coating of a panel requires spraying both sides of the panel. Currently, most operators spray one side, remove it from the fixture, flip it over, and then spray the other side. The whole process is time-consuming and labor-intensive, and the spraying efficiency is low. Therefore, this paper proposes a flipping mechanism for coating, which facilitates the rapid spraying of both sides of the panel. Utility Model Content

[0004] The purpose of this invention is to provide a coating flipping mechanism to solve the problems mentioned in the background art.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A coating flipping mechanism includes a spray chamber (100) and a flipping mechanism (200). The flipping mechanism (200) includes a rotating shaft (2003) rotatably connected to the top surface of the spray chamber (100). The bottom end of the rotating shaft (2003) is connected to a connecting frame (2006) located inside the spray chamber (100). The flipping mechanism (200) also includes a driving member that drives the rotating shaft (2003) to rotate. The connecting frame (2006) is U-shaped. A crossbar (2007) is installed in the groove of the connecting frame (2006). A pair of fixing members (300) slide on the outside of the crossbar (2007). The pair of fixing members (300) fix plates.

[0007] Furthermore, the driving component includes a motor (2001) mounted on the top surface of the spray chamber (100), the output end of the motor (2001) is connected to a worm gear (2002), and a worm wheel (2004) is mounted on the outer side of the rotating shaft (2003), the worm gear (2002) and the worm wheel (2004) meshing.

[0008] Furthermore, a micro switch (2008) is installed on the outer side of the rotating shaft (2003), and the button of the micro switch (2008) is set downward. Four sets of protrusions (2009) are installed on the top surface of the spray chamber (100), and the four sets of protrusions (2009) are evenly distributed along the circumference of the rotating shaft (2003). The protrusions (2009) and the micro switch (2008) are pressed together, and the micro switch (2008) is electrically connected to the motor (2001).

[0009] Furthermore, a start button (2005) is installed on the side of the spray booth (100), and the start button (2005) is electrically connected to the motor (2001).

[0010] Specifically, the motor (2001) is started using the start button (2005). Since the start button (2005) is located on the outside of the spray booth (100), it is easy for the user to press the start button (2005). The motor (2001) drives the rotating shaft (2003) to rotate through the worm gear (2002) and worm wheel (2004), thereby causing the connecting frame (2006) to rotate. When the plate is fixed under the connecting frame (2006), it can drive the plate to rotate together, thereby completing the flipping of the plate. Utilizing the self-locking ability of the worm gear (2002) and worm wheel (2004), the plate can be fixed in the rotated position. When the rotating shaft (2003) rotates to a certain angle, the button of the micro switch (2008) will be squeezed by the protrusion (2009). When the rotating shaft (2003) rotates to a certain angle again, the button of the micro switch (2008) will disengage from the protrusion (2009). At this time, the step of pressing the micro switch (2008) is completed. After this step is completed, the micro switch (2008) will control the motor (2001) to stop, thereby stopping the rotating shaft (2003). The rotating shaft (2003) rotates 90 degrees each time, thereby rotating the board 90 degrees each time. In this way, the user can spray paint on all four sides of the board.

[0011] Furthermore, each of the pair of fixing members (300) includes a sleeve (3001), which slides on the outside of the crossbar (2007). A pull rod (3003) is installed on the outside of the sleeve (3001), and a U-shaped sleeve (3004) is installed at the bottom end of the pull rod (3003). A threaded rod (3005) is threadedly connected to one side of the U-shaped sleeve (3004). A rubber pad (3006) is installed at one end of the threaded rod (3005), which is located inside the U-shaped sleeve (3004). A knob (3007) is coaxially connected to the other end of the threaded rod (3005), which is located outside the U-shaped sleeve (3004).

[0012] Furthermore, a limiting strip (3002) is installed on the inner wall of the sleeve (3001), and a limiting groove is opened on the outer side of the crossbar (2007), and the limiting strip (3002) slides in the limiting groove.

[0013] Specifically, the limiting strip (3002) and the limiting groove are used to ensure that the sleeve (3001) can only move horizontally. A pair of horizontally movable sleeves (3001) can change the distance between adjacent ones to accommodate plates of different widths. The edge of the plate can be placed in the U-shaped sleeve (3004). When the knob (3007) is pinched and rotated, the threaded rod (3005) can be rotated, thereby causing the rubber pad (3006) to move towards the plate and clamp the plate, so that the plate is suspended and fixed in the spray chamber (100). At this time, the user can spray the plate.

[0014] Furthermore, the bottom surface of the spraying chamber (100) is provided with several water outlet holes.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the paint flows out from the water outlet, preventing liquid accumulation at the bottom of the spray chamber (100).

[0016] Compared with the prior art, the beneficial effects of this utility model are: the coating flipping mechanism uses a drive component to drive the rotating shaft to rotate 180 degrees, so that the fixed plate is flipped over, allowing the user to spray the back of the plate. Moreover, the whole process does not require removing the plate, flipping it over and fixing it again, thereby improving the ease of spraying for the user. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 4This utility model provides a technical solution: a coating flipping mechanism, wherein a pair of fixing members 300 each include a sleeve 3001, the sleeve 3001 sliding on the outside of a crossbar 2007, a pull rod 3003 is installed on the outside of the sleeve 3001, a U-shaped sleeve 3004 is installed at the bottom end of the pull rod 3003, a threaded rod 3005 is threadedly connected to one side of the U-shaped sleeve 3004, a rubber pad 3006 is installed at one end of the threaded rod 3005, the rubber pad 3006 is located inside the U-shaped sleeve 3004, and a knob 3007 is coaxially connected to the other end of the threaded rod 3005, the knob 3007 is located outside the U-shaped sleeve 3004, and the sleeve 3001... The inner wall is equipped with a limiting strip 3002, and the outer side of the crossbar 2007 is provided with a limiting groove. The limiting strip 3002 slides in the limiting groove. The limiting strip 3002 and the limiting groove are used to ensure that the sleeve 3001 can only move horizontally. A pair of horizontally movable sleeves 3001 can change the distance between adjacent ones to accommodate plates of different widths. The edge of the plate can be placed in the U-shaped sleeve 3004. When the knob 3007 is squeezed and rotated, it can drive the threaded rod 3005 to rotate, thereby moving the rubber pad 3006 towards the plate and clamping the plate, so that the plate is suspended and fixed in the spray chamber 100. At this time, the user can spray the plate.

[0028] Specifically, the working principle of this coating flipping mechanism is as follows: During use, adjust the distance between a pair of sleeves 3001 according to the width of the sheet material. Place the edge of the sheet material inside the U-shaped sleeve 3004, then pinch and rotate the knob 3007 to rotate the threaded rod 3005. This causes the rubber pad 3006 to move towards the sheet material and clamp it, suspending the sheet material in the spray chamber 1001. The user can then spray the sheet material. After one side is sprayed, press the start button 2005 to start the motor 2001. 2001 drives the rotating shaft 2003 to rotate via the worm gear 2002 and worm wheel 2004, thereby causing the connecting frame 2006 to rotate the plate 90 degrees together. Then the motor 2001 stops, and the user sprays the other side. The above steps are repeated until all four sides are sprayed. Then the plate is removed and fixed by the other side. Then the areas that were not sprayed when it was fixed last time are sprayed. Finally, the plate is removed again, and the plate is placed flat in the spraying chamber 100. The remaining two sides of the plate are then sprayed.
