Description

Technical Field

[0001] This utility model belongs to the field of steel portable can processing and manufacturing, and specifically relates to an automatic spraying device for portable cans. Background Technology

[0002] Steel portable cans are used to store refined chemical substances such as acids, alkalis, alcohols, gases, and liquids. These tanks are widely used in North China and, depending on the material, generally include: polyethylene tanks, polypropylene tanks, fiberglass tanks, ceramic tanks, and steel portable cans. In terms of cost-effectiveness, steel portable cans are currently considered the best, offering excellent corrosion resistance, high strength, and long service life. The surface of steel portable cans needs to be painted to ensure their corrosion resistance.

[0003] Currently, the can processing workshop still uses manual spray guns to spray paint the cans. The disadvantage of this method is that the spraying efficiency is too low, which affects the efficiency of can processing and manufacturing. Utility Model Content

[0004] The purpose of this invention is to provide an automatic spraying device for portable cans, which can automatically spray paint onto portable cans, greatly improving spraying efficiency and increasing the degree of automation.

[0005] The purpose of this utility model is achieved as follows: An automatic spraying device for a portable can includes a C-shaped fixed base, on which a plurality of rotatable driven gears are arranged at intervals along the circumference. A circular rotating frame is correspondingly provided in the middle of the fixed base. A gear ring is provided on the outer periphery of the rotating frame corresponding to each driven gear. The gear ring of the rotating frame meshes with the corresponding driven gear. A plurality of universal wheels are provided at the bottom of the rotating frame. The driven gears are connected to a rotary drive mechanism. A vertical support frame is provided on the rotating frame. A plurality of inclined hanging rods are provided on the support frame. A top mounting frame is provided corresponding to the support frame. A plurality of downward-facing spray nozzles are installed on the top mounting frame.

[0006] As a further improvement of this utility model, the gear ring is C-shaped, and the support frame includes two symmetrically arranged side supports on the rotating frame. Between the two side supports are several transverse mounting beams arranged sequentially from top to bottom. Each mounting beam has several upwardly inclined hanging rods evenly spaced along its length. The canister is suspended by these hanging rods.

[0007] As a further improvement of this utility model, the hanging rods on the two adjacent mounting beams are staggered along the length direction.

[0008] As a further improvement of this utility model, the top mounting bracket is circular, and multiple paint supply pipes are provided on the lower side of the top mounting bracket. Each paint supply pipe has multiple nozzles spaced apart along its length. Several vertical support columns are provided on the lower side of the outer edge of the top mounting bracket, evenly distributed circumferentially. The paint supply pipes are connected to the paint pipes, and the paint is delivered to the nozzles by a pump for spraying the can.

[0009] As a further improvement of this utility model, the support column is supported on the ground, and a pit is provided below the fixed seat and the rotating frame. A collection trough is provided in the pit, and a grid plate is provided above the collection trough at the corresponding position of the pit. The fixed seat and the rotating frame are mounted on the grid plate. Excess paint after spraying enters the collection trough.

[0010] As a further improvement of this utility model, the rotary drive mechanism includes a vertical gantry frame corresponding to each driven gear. A transverse rotating shaft is rotatably mounted on the upper part of the frame. Both ends of the rotating shaft are provided with bevel gears. Either end of the rotating shaft passes through the corresponding bevel gear and is connected to a reduction motor. A transmission rod is vertically mounted on the frame, rotatably below both bevel gears. The upper end of the transmission rod is provided with a bevel gear that meshes with the corresponding bevel gear, and the lower end of the transmission rod is provided with a driving gear. The two driving gears are located at both ends of the C-shaped fixed base, and are meshed with a gear ring. The reduction motor drives the rotating shaft to rotate, the bevel gears drive the bevel gears to rotate, and the transmission rod rotates. The gear ring rotates via the driving gears. The two driving gears and the bevel gears rotate in opposite directions. One driving gear meshes with the gear ring, and the two driving gears drive the gear ring to reciprocate.

[0011] In operation, the portable can to be painted is suspended on a hanging rod, with the rod inserted into the can's opening. A reduction motor drives a rotating shaft, which in turn drives a second bevel gear. This rotation of the transmission rod, in turn, drives a gear ring to rotate via a drive gear. The two drive gears and the second bevel gear rotate in opposite directions, causing the gear ring to reciprocate. This rotation of the rotating frame, along with the steel portable can on the support frame, causes the spray nozzle to automatically spray paint onto the can. Compared to existing technologies, the advantages of this invention are: it enables automatic painting of portable cans, significantly improving painting efficiency and achieving a higher degree of automation.
