Description

Technical Field

[0001] This utility model relates to the field of spraying equipment technology, specifically a hanger for spraying parts. Background Technology

[0002] Powder coating is a process in which solid powder coatings are uniformly applied to the surface of a workpiece through electrostatic adsorption or fusion adhesion, and then cured at high temperature to form a dense coating. This technology, with its advantages of zero solvent evaporation, extremely high coating utilization, and adjustable single-coat thickness, has become a mainstream surface treatment solution in metal products, building materials, and automotive parts. The core of powder coating lies in electrostatic adsorption and thermal curing. After being charged in a high-voltage electrostatic field, powder particles are uniformly adsorbed onto the grounded workpiece surface through airflow, and then melted and leveled during high-temperature baking, forming a hard coating through chemical cross-linking. In the automotive industry, powder coating has been applied to plastic parts such as grilles and door handles, and gradient processes are used to achieve three-dimensional light and shadow effects on car logos; in the home appliance industry, antibacterial powder coatings use silver ion additives to inhibit microbial growth, meeting health requirements. During powder coating, parts are usually hung on racks to facilitate uniform adsorption of the powder coating onto the part's surface.

[0003] To prevent workpieces from contacting or colliding with each other due to wind during spraying, they need to be evenly and securely hung on the bottom of the hanger using a fixture. However, existing hangers are difficult to balance even fixation of the bottom fixture with quick assembly and disassembly, resulting in poor flexibility and affecting the spraying efficiency of the workpieces.

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-3This embodiment of a parts spraying hanger includes a base 1. A pair of vertical rods 2 are symmetrically and vertically fixedly connected to the top two sides of the base 1. A pair of mounting brackets 3 are symmetrically and fixedly connected to the top of the pair of vertical rods 2. A hanging rod 4 is detachably and horizontally arranged on the top of the mounting bracket 3. Several hanging holes 5 are evenly distributed at the bottom of the hanging rod 4. Several hooks 7 are detachably arranged at the bottom of the hanging rod 4 through the hanging holes 5. A hanging fixture 6 is fixedly connected to the bottom of each hook 7. A limiting mechanism 10 is provided between the top of the side walls of the pair of vertical rods 2 for quickly limiting and positioning the hooks 7. The limiting mechanism 10 includes a limiting frame 1001, and a first sliding rod 1002 is slidably connected parallel to the top of the limiting frame 1001. The first slide rod 1002 and the second slide rod 1003 are provided with several sets of clamping blocks 1009 evenly and detachably. The first slide rod 1002 and the second slide rod 1003 are arranged parallel to the hanging rod 4. The first slide rod 1002 and the second slide rod 1003 are respectively located on the bottom sides of the hanging rod 4. A pair of mounting rods 1006 are symmetrically and horizontally fixedly connected to the inner sides of both ends of the limiting frame 1001. A gear 1007 is rotatably connected to the top side of the middle part of each mounting rod 1006. A rack 1008 is provided at both ends of the side wall of the first slide rod 1002 and the second slide rod 1003 facing the gear 1007. The rack 1008 is meshed with the gear 1007. During spraying, the workpiece is evenly hung on the hanger 6, and then the fully loaded hanger 6 is hung in the hanging hole 5 at the bottom of the hanger rod 4 through the hook 7 at the top. During hanging, the hook 7 is positioned in the middle of the clamping block 1009, and the clamping block 1009 is used to quickly position the hanging position of the hook 7. After the hanger 6 is hung, the second slide rod 1003 is pushed axially towards the limit frame 1001, causing the rack 1008 on its side wall to move accordingly. When the rack 1008 moves, it drives the gear 100 meshing with it. 7 rotates accordingly, causing the rack 1008 on the other side of gear 1007 to move in the opposite direction, thereby driving the first slide bar 1002 and the second slide bar 1003 to move towards each other, causing the clamping block 1009 between the first slide bar 1002 and the second slide bar 1003 to move towards each other, synchronously limiting and fixing the hook 7 between the clamping blocks 1009, thereby limiting and fixing the hanger 6 at the bottom of the hook 7 and the workpiece, preventing the workpiece from contacting or colliding due to wind force during spraying, and effectively improving the applicability of the hanger.

[0022] Mounting rod 1006 is perpendicular to hanging rod 4. A pair of rotating shafts 1004 are fixedly connected axially to both ends of the second slide rod 1003. A pair of limiting rods 1005 are rotatably connected to the end of one rotating shaft 1004 away from the second slide rod 1003. The limiting rods 1005 are perpendicular to the rotating shafts 1004. After the first slide rod 1002 and the second slide rod 1003 move to the clamping position, the limiting rods 1005 at both ends of the second slide rod 1003 are rotated, causing the limiting rods 1005 to rotate to the outside of both sides of the vertical rod 2, thus limiting the second slide rod 1003 and preventing it from loosening during workpiece spraying.

[0023] Please see Figure 4 The hanger 6 includes several horizontally parallel placement rods 8, and the side walls of the placement rods 8 are evenly provided with several connection holes 9. When hanging the workpiece, it is evenly placed outside the connection holes 9 on the side walls of the placement rods 8 to avoid collision and contact between adjacent workpieces.

[0024] Several rollers 11 are rotatably connected to the bottom of the base 1. The rollers 11 allow for quick transfer of the hanger, improving its versatility.

[0025] Working principle: During spraying, the workpiece is evenly hung on the hanger 6. During hanging, the workpiece is evenly placed outside the connecting holes 9 on the side wall of the placement rod 8 to avoid collisions between adjacent workpieces. Then, the fully loaded hanger 6 is hung in the hanging hole 5 at the bottom of the hanging rod 4 through the hook 7 at the top. During hanging, the hook 7 is positioned in the middle of the clamping block 1009, and the clamping block 1009 quickly positions the hook 7. After the hanger 6 is hung, the second slide rod 1003 is pushed axially towards the limit frame 1001, causing the rack 1008 on its side wall to move accordingly. When the rack 1008 moves, it drives the gear 1007 meshing with it to rotate, causing the rack 1008 on the other side of the gear 1007 to rotate along the same direction. The movement begins in the opposite direction, causing the first slide bar 1002 and the second slide bar 1003 to move towards each other. This causes the clamping block 1009 between the first slide bar 1002 and the second slide bar 1003 to move towards each other, synchronously limiting and fixing the hook 7 between the clamping blocks 1009. This limits and fixes the hanger 6 at the bottom of the hook 7 and the workpiece, preventing the workpiece from contacting or colliding with the wind during spraying, effectively improving the applicability of the hanger. After the first slide bar 1002 and the second slide bar 1003 move to the clamping position, the limiting rods 1005 at both ends of the second slide bar 1003 are rotated, causing the limiting rods 1005 to rotate to the outside of both sides of the vertical bar 2, limiting the second slide bar 1003 and preventing it from loosening during workpiece spraying.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
