Description

Technical Field

[0001] The utility model relates to the technical field of coating devices, and more particularly to a metal coating coating device used for parts processing. Background Art

[0002] With the development of science and technology and the progress of the times, people's requirements for all aspects of quality of life are getting higher and higher. With the processing of various metal parts, various types of pigments are sprayed on the surface of metal parts to extend the service life of metal parts and have a certain aesthetic appearance. Therefore, a metal coating coating device is needed.

[0003] The spraying of smaller non-standard hardware parts is mostly done by hanging them on a hanger. During use, multiple hardware parts need to be manually hung on the hanger one by one. During the hanging process, all spraying operations need to be suspended and spraying can only be carried out after all the hanging is completed.

[0004] In order to improve the spraying efficiency of small-sized parts, a tumble dryer has been developed on the market. It uses a rolling screen inside to turn the parts over by rotation, and then connects to the nozzle for uniform spraying. It is also equipped with a drying structure to blow hot air out of the screen to dry the sprayed parts, thus achieving the effect of spraying and drying layer by layer at the same time.

[0005] However, in actual use, the parts are always concentrated at the lower edge in the screen barrel. When there are too many parts, the parts block each other and the hot air can hardly reach every part. The spraying rate needs to be lowered and the drying power increased to ensure that each layer of paint can dry in time, which affects the drying efficiency of the parts and limits the number of parts that can be sprayed at the same time.

[0006] Therefore, in order to solve the above technical problems, the present application proposes a metal coating application device for parts processing. Utility Model Content

[0007] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a metal coating application device for parts processing.

[0008] To achieve the above-mentioned object, the present utility model provides the following technical solution: the metal coating application device for parts processing comprises a swing drying rack rotatably connected to the top of the cone through a connecting rod;

[0009] The swing drying rack includes a flip plate, and flip guard plates are provided at both ends of the flip plate in mirror symmetry, and side guard plates are provided on both sides of the flip plate to prevent the parts to be sprayed from sliding out. The flip guard plates are arranged in an arc shape with an opening facing inward so that the parts can be turned over along the arc for more uniform spraying. The flip guard plates and the flip plate are hollow inside and are connected to a drying assembly, and the flip guard plates and the flip plate are both provided with a mesh structure on the inner side for blowing out hot air to dry the coating on the surface of the parts;

[0010] A group of electric lifting rods are provided on each side of the frustum. The lifting ends of the electric lifting rods are rotatably connected to the side of the flip plate facing the frustum. By extending the electric lifting rod on one side and lowering the lifting rod on the other side, the opening of the flip plate can be tilted toward the side where the electric lifting rod is lowered. The parts are rolled and spread out on the flip plate for drying to avoid stacking and blocking each other.

[0011] Preferably, a contact component is provided at the connection between the flip plate and the frustum after rotation, and the contact component includes a protrusion arranged on the surface of the flip plate, a first electrode sheet is provided at the front end of the protrusion, a groove is provided on the slope of the frustum to facilitate the protrusion to be snapped into, and a second electrode sheet is provided at the bottom of the groove for contacting with the first electrode sheet to connect the circuit.

[0012] Preferably, a group of paint nozzles are respectively provided at both ends of the swing drying rack, the paint nozzles are installed on the support frame, and the paint nozzles are connected to a paint assembly for providing the required paint.

[0013] Preferably, the first electrode sheet and the second electrode sheet communication circuit are electrically connected to the paint nozzle brake switch, so as to control the paint spraying timing through the connection of the contact component, so that the paint nozzle switch on this side is triggered to open after the swing drying rack is flipped to the corresponding side.

[0014] Preferably, the groove is opened perpendicular to the frustum slope, and the depth of the groove is greater than the height of the protrusion to avoid limiting the rotation angle of the flip plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the utility model, a group of electric lifting rods are provided on both sides of the bottom of the swing drying rack. The swing drying rack is flipped by the lifting and lowering of the electric lifting rods, so that the parts can be evenly spread on the swing drying rack, achieving the technical effect of uniform drying and improving drying efficiency, thereby solving the problem in the prior art that the parts are always concentrated at the lower edge in the screen barrel. When there are too many parts, the parts block each other, and the hot air is difficult to blow to every part. It is necessary to reduce the spraying rate and increase the drying power to ensure that each layer of paint can be dried in time, which affects the drying efficiency of the parts and limits the number of parts that can be sprayed at the same time.

[0017] 2. In the present invention, a touch component is provided to control the opening of the paint nozzles on both sides. When the swing drying rack is flipped, the paint nozzles on the corresponding side will open to spray paint, thereby avoiding waste of paint and giving sufficient drying time to the parts, thereby improving drying efficiency.

[0032] like Figure 1-4 As shown, a metal coating application device for parts processing includes a swing drying rack 2 rotatably connected to the top of a frustum 1 through a connecting rod 3;

[0033] The swing drying rack 2 includes a flip plate 22, with flip guard plates 21 provided at both ends of the flip plate 22 in mirror symmetry, and side guard plates 23 provided on both sides of the flip plate 22 to prevent the parts to be sprayed from slipping out. The flip guard plate 21 is set to an arc shape with an opening facing inward so that the parts can be turned over along the arc for more uniform spraying. The flip guard plate 21 and the flip plate 22 are hollow inside and are connected to the drying assembly, and the flip guard plate 21 and the flip plate 22 are both provided with a mesh structure on the inner side for blowing out hot air to dry the coating on the surface of the parts;

[0034] A set of electric lifting rods 4 are provided on each side of the cone 1. The lifting ends of the electric lifting rods 4 are rotatably connected to the side of the flip plate 22 facing the cone 1. The electric lifting rod 4 on one side is extended and the lifting rod on the other side is lowered. The swing drying rack 2 is rotatably connected to the top of the cone 1 through the connecting rod 3. The connection point can be used as a rotation point to tilt the opening of the flip plate 22 toward the side where the electric lifting rod 4 is lowered. The parts are rolled and spread out on the flip plate 22 for drying to avoid stacking and blocking each other.

[0035] The flip plate 22 rotates with the cooperation of the lifting rods on both sides until the bottom of the flip plate 22 is in contact with the surface of the frustum 1. The movement direction of the lifting rods on both sides is reversed, so that the flip plate 22 rotates in the opposite direction and the opening tilts toward the other side.

[0036] The parts to be sprayed are placed on the flip plate 22 of the swing drying rack 2. As shown in the accompanying drawings, the swing drying rack 2 is similar to a drawer with arc-shaped sides. The side guard plates 23 form a protection to prevent the parts from sliding when the flip plate 22 rotates. When the arc-shaped flip guard plate 21 is driven by the flip plate 22 to rotate to the lowest angle and lift up, the parts inside the flip guard plate 21 flip over and fall back onto the flip plate 22, completing the flip;

[0037] When the flip plate 22 rotates and tilts, the parts will remain spread out on the flip plate 22, so that the possibility of blocking between parts during spraying and drying is reduced, thereby improving the efficiency of spraying and drying;

[0038] Therefore, by arranging a set of electric lifting rods 4 on both sides of the bottom of the swing drying rack 2, the electric lifting rods 4 are raised and lowered to control the flipping of the swing drying rack 2, so that the parts can be evenly spread on the swing drying rack 2, achieving the technical effect of uniform drying and improving drying efficiency, thereby solving the problem in the prior art that the parts are always concentrated at the lower edge in the sieve barrel. When there are too many parts, the parts are blocked from each other, and the hot air is difficult to blow to every part. It is necessary to reduce the spraying rate and increase the drying power to ensure that each layer of paint can be dried in time, which affects the drying efficiency of the parts and limits the number of parts that can be sprayed at the same time.

[0039] A contact assembly 5 is provided at the connection between the flip plate 22 and the frustum 1 after rotation. The contact assembly 5 includes a protrusion 51 provided on the surface of the flip plate 22. A first electrode sheet 53 is provided at the front end of the protrusion 51. A groove 52 is provided on the slope of the frustum 1 to facilitate the insertion of the protrusion 51. A second electrode sheet 54 is provided at the bottom of the groove 52 for contacting the first electrode sheet 53 to connect the circuit.

[0040] A set of paint nozzles 7 are provided at each end of the swing drying rack 2. The paint nozzles 7 are mounted on the support frame 6, and the paint nozzles 7 are connected to a paint assembly for providing the required paint.

[0041] The first electrode sheet 53 and the second electrode sheet 54 are connected to the circuit and electrically connected to the brake switch of the paint nozzle 7, thereby controlling the paint spraying timing through the connection of the contact component 5, so that the paint nozzle 7 switch on the corresponding side is triggered to turn on after the swing drying rack 2 is turned to the corresponding side;

[0042] The groove 52 is opened perpendicular to the slope of the cone 1, and the depth of the groove 52 is greater than the height of the protrusion 51 to avoid limiting the rotation angle of the flip plate 22;

[0043] When the flip plate 22 rotates with the cooperation of the electric lifting rods 4 on both sides, after the flip plate 22 is attached to the frustum 1, the first pole piece will come into contact with the second pole piece, connecting the switch of the paint nozzle 7 on the corresponding side. At this time, the opening of the swing drying rack 2 is facing the paint nozzle 7 on the corresponding side. The switch is set to be closed with a delay, and the lifting rod pushes the flip plate 22 to rotate in the opposite direction. During this process, the paint nozzle 7 continues to spray according to the delay time and stops when the flip plate 22 rotates to the horizontal state;

[0044] Because the parts are relatively scattered on the flip plate 22, the existing method of setting a paint nozzle 7 above the rotation center will reduce the number of parts sprayed per unit time. If continuous spraying is set on both sides of the opening, the paint spraying will be sprayed on the bottom of the flip plate 22 instead of the parts when the opening of the swing drying rack 2 is facing away from the paint nozzle 7. Therefore, the intermittent spraying method on both sides is adopted to improve the spraying efficiency and avoid paint waste.

[0045] Therefore, by setting the touch component 5 to control the paint nozzles 7 on both sides to open, when the swing drying rack 2 is flipped, the paint nozzles 7 on the corresponding side will open to spray paint, avoiding paint waste while giving the parts enough drying time and improving drying efficiency.

[0046] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
