Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to a paint spray drying device. Background Art

[0002] The paint drying device is a device used to accelerate the drying process of the coating after painting. It is widely used in the manufacturing industries such as automobiles, furniture, and electronic products. In the spraying process, the paint is evenly sprayed on the surface of the workpiece through a spray gun to form a protective layer and a decorative layer. The drying process after painting is crucial to the quality and production efficiency of the coating, and directly affects the adhesion, wear resistance and appearance of the coating.

[0003] The existing drying method is to place the sprayed parts in an oven and dry them by heating and air circulation in the oven. However, some parts are sprayed as a whole and need to be hung for drying. The hanging position of existing drying equipment is mostly fixed, and it is not easy to adjust the spacing according to the size of different parts. Too large a spacing will reduce production efficiency, and too small a spacing will cause collisions between parts, affecting quality. This requires a device to solve the above problems.

[0006] The hanging mechanism includes a chute, a movable block and a hanging ring. The chute is opened on one side of the connecting rod. The movable block is slidably arranged on the inner wall of the chute. The hanging ring is fixedly connected to the bottom of the movable block for hanging the product.

[0007] A driving mechanism is provided inside the shell for driving the connecting rod to move.

[0008] Optionally, the driving mechanism is a driving gear, and the driving gear is connected to the output end of the driving motor through a keyway.

[0009] Optionally, a rack is provided on the upper surface of the connecting rod, and the outer circular surface of the driving gear is engaged with the inner wall of the rack to drive the connecting rod to move.

[0010] Optionally, the internal thread of the movable block is connected with a fixing bolt, and one end of the fixing bolt is pressed against the inner wall of the connecting rod.

[0011] Optionally, a protective door is connected to the front of the shell via a hinge, and an auxiliary plate is provided at the opening of the drying chamber.

[0012] Optionally, an air intake mechanism is provided on one side of the shell, an exhaust mechanism is provided on the top of the shell, and a heating wire is provided in the air intake mechanism for heating the internal air.

[0013] The utility model provides a paint spray drying device, which has the following beneficial effects:

[0014] The utility model provides a paint drying device. Through the coordinated arrangement of a connecting rod, an expansion plate, an auxiliary hook and a hanging ring, parts to be dried can be hung at the bottom, so that hot air can dry the paint on the surface of the parts. Through the coordinated arrangement of a slide groove and a movable block, the position of the movable block can be adjusted by sliding the movable block in the slide groove, thereby adjusting the position of the hanging ring at the bottom of the movable block. When hanging parts of different sizes, the spacing between the hanging rings can be adjusted, which is convenient for adjustment during the drying operation and more flexible to adapt to different situations when used.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] See also Figures 1 to 4The utility model provides a technical solution: a paint spray drying device, comprising a shell 1, a drying chamber 2 is provided inside the shell 1, a retractable connecting rod 3 is provided on the inner top wall of the drying chamber 2, a hanging mechanism is provided at the bottom of the connecting rod 3, expansion plates 4 are fixedly connected to both sides of the connecting rod 3, and an auxiliary hook 5 is fixedly connected to the bottom of the expansion plate 4;

[0022] The hanging mechanism includes a chute 6, a movable block 7 and a hanging ring 8. The chute 6 is opened on one side of the connecting rod 3. The movable block 7 is slidably arranged on the inner wall of the chute 6. The hanging ring 8 is fixedly connected to the bottom of the movable block 7 for hanging the product.

[0023] A driving mechanism is provided inside the housing 1 for driving the connecting rod 3 to move.

[0024] The inner wall of the drying bin 2 is provided with a heat insulation mechanism to maintain the temperature inside the drying bin 2 and improve the energy utilization efficiency. The connecting rod 3 can be extended from the inside of the shell 1 to facilitate the operator to hang the parts on the bottom ring 8. The expansion plate 4 is provided on both sides of the connecting rod 3. At the same time, a plurality of auxiliary hooks 5 are provided at the bottom. When hanging the parts, the connecting rope can be used to hang on the auxiliary hook 5 to adjust the position of the parts to reduce the possibility of collision between parts. The movable block 7 can slide in the slide 6 to adjust the position of the bottom ring 8. A notch is provided at one end of the connecting rod 3 located inside the drying bin 2, and the number of movable blocks 7 in the slide 6 can be adjusted. The spacing and quantity are matched. The driving mechanism can drive the connecting rod 3 to move and extend or retract the connecting rod 3.
