Description

Technical Field

[0001] This utility model relates to the technical field of metal barrel production equipment, and in particular to an auxiliary device for painting metal barrels. Background Technology

[0002] Metal drums are widely used for the transfer of various liquid materials. In order to prevent the metal drums from being corroded by the materials, an anti-corrosion coating needs to be sprayed on the inner wall of the metal drum during the production and processing process, so that there is a uniformly thick isolation film between the inner wall of the steel drum and the contents.

[0003] To increase the speed of coating the inner wall of metal drums, automatic spraying equipment is generally used. However, existing metal drum spraying equipment can only achieve single-function automatic spraying and cannot automatically load and unload the drums. Manual placement and removal of the metal drums are required, which greatly reduces the production efficiency. Utility Model Content

The feeding mechanism includes a feeding rotary arm and a rotating base. The feeding rotary arm is Y-shaped. Three feeding rotary arms are fixedly installed at equal intervals around the periphery of the rotating base. A drive shaft is fixedly installed at the bottom of the rotating base. The drive shaft is rotatably mounted on the material-carrying chassis via bearings. The material-carrying chassis has a feed inlet, a spraying outlet, and a feeding outlet in sequence. The clamping mechanism includes a clamping block and two clamping plates fixedly mounted on both sides of the clamping block. The device includes a clamping block with a roller groove on one side, in which a clamping roller is installed. A fixing frame is fixedly installed on one side of the bottom of the support plate, and a first motor is mounted on the fixing frame. A rotating through hole is opened at the bottom of the support plate. A reducer is powered to one end of the first motor. The feeding mechanism is fixedly installed on the support plate via a support column. The spraying mechanism is fixedly installed on the support plate. The clamping block is slidably mounted on the support plate. The clamping block and the spraying mechanism are located on one side of the spray nozzle. The clamping block is located below the spraying mechanism. One end of the drive shaft passes through the support plate and is powered to the output end of the reducer.

[0006] Preferably, the feeding arm has a clamping groove at one end near the metal bucket, and several rotating rollers are rotatably mounted in the clamping groove, with each roller protruding from the opening of the groove. The clamping groove is used to accommodate the metal bucket, and the rotating rollers fit snugly against the side of the metal bucket to facilitate its rotation.

[0007] Preferably, a connecting column is fixedly installed at the center of the top of the rotating base, and a protective cover is fixedly connected to the top of the connecting column. The protective cover has three receiving openings corresponding to the inlet, spray nozzle, and feed port, respectively.

Each reciprocating device includes a reciprocating connecting plate and an air pump. The reciprocating connecting plate is fixedly installed on one side of the clamping block, and the air pump is fixedly installed below the material-carrying chassis. One end of the air pump's push rod is fixedly connected to the reciprocating connecting plate. The air pump's push rod pushes the reciprocating connecting plate back and forth, causing it to drive the clamping block to reciprocate, thereby fixing the metal bucket.

[0009] Preferably, one end of the rotating shaft of the clamping roller protrudes through the roller groove and extends from the top of the clamping block. A second motor is fixedly mounted on the top of the clamping block, and the second motor is poweredly connected to the rotating shaft via a belt.

One side of the nozzle is fixedly mounted on one end of the short side of the spraying pipe, and one end of the long side of the spraying pipe is connected to an external paint pump. The spraying mechanism is mainly responsible for coating the metal bucket. Two fixed rods serve to fix the installation. The mounting plate connects the two fixed rods. The connecting plate is located below the mounting plate and is away from the metal bucket. The fourth motor drives the threaded rod to rotate. The connecting seat sleeved on the threaded rod moves up and down with the rotation of the threaded tube. The sliding rod keeps the connecting seat stable and prevents it from rotating. The spraying tube is fixedly installed below the connecting seat by the clamping block. One end of the tube is connected to the external paint pump, and the other end extends downward to connect to the spray nozzle, allowing the spray nozzle to penetrate into the metal bucket for spraying.

[0014] Preferably, a plurality of support legs are fixedly installed at the bottom of the support plate, and a protective skirt is fitted onto the bottom of the support plate. The support legs serve to support the entire device, and the protective skirt is used to protect the motor and the reducer.

[0037] In use, the metal drum 15 to be processed is first transported to the feed inlet 501 and the receiving inlet 109 by an external conveyor belt. When the metal drum 15 enters the feed inlet 501, several rotating rollers 106 on the inner wall of the feeding arm 101 come into contact with the outer wall of the metal drum 15. The first motor 302 starts and transmits power to the drive shaft 104 through the reducer 304, driving the rotating base 102 to rotate. The feeding arm 101 rotates accordingly. When the feeding arm 101 carrying the metal drum 15 rotates to the infrared fixed position... When the positioner 506 is in place, the rotating base 102 stops rotating. At this time, the metal barrel 15 is located on the rotating tray 504 in the spray nozzle 502. The clamping mechanism 2 is activated, and the air pump 602 pulls the reciprocating connecting plate 601, causing the clamping block 201 to move towards the metal barrel 15 until the clamping roller 203 on the clamping block 201 is in contact with the outer wall of the metal barrel 15, so that the metal barrel 15 is clamped by the clamping roller 203 and the rotating roller 106. At this time, the second motor 204 is activated and drives the clamping roller 203 to rotate via the belt. The roller 203 drives the metal bucket 15 to rotate on the rotating tray 504, the spraying mechanism 4 starts, and the fourth motor 9 drives the threaded rod 407 to rotate. The connecting seat 403, which is sleeved on the threaded rod 407 and the slide rod 7, moves the spraying pipe 401 and the nozzle 402 downward. When the nozzle 402 enters the spraying area in the metal bucket 15, the paint is pumped out from the external paint pump, passes through the spraying pipe 401, and finally sprays out from the nozzle 402. The fourth motor 9 rotates in the opposite direction, and the connecting seat 403 moves the spraying pipe 401 and the nozzle 402 downward. The upper displacement enables spraying inside the metal barrel 15. After spraying is completed, the connecting seat 403 continues to rise until the nozzle detaches from the metal barrel 15. At this time, the feeding arm 101 continues to rotate, transferring the sprayed metal barrel 15 to the feeding port 503. The feeding roller 507 in the feeding port 503 is driven by the third motor 508 to lower the metal barrel 15 and transfer it out of the feeding port. Repeating the above process can realize automatic loading and unloading of the metal barrel after spraying. The whole device has a compact structure, can save labor costs, and greatly improve production efficiency.
