Description

Automatic recoating device

Technical field

The invention relates to an automatic recoating device.

Background technique

In the metal container manufacturing industry, chemical round cans are a typical product, and the production process is relatively complicated. The treated tinplate pieces are subjected to rounding, seam welding, flanging, welding of welding ears, and recoating. The solder lug is a connector for mounting with a handle. The existing main welding ear operation method: the welding headphone completes the work. When welding the earphones, it is generally necessary to first perform weld positioning on the barrel-shaped can body. The existing recoating method is mainly manual brushing, that is, after the welding lug is completed, the contact point of the inner ear of the tank needs to be recoated to prevent rusting of the part. The manual brushing efficiency is low, and it is unable to adapt to the existing automatic equipment, and the amount of brushing is not easy to control, and subjective.

Summary of the invention

In order to overcome the above disadvantages, it is an object of the present invention to provide an automatic recoating device.

In order to achieve the above object, the technical solution adopted by the present invention is: an automatic recoating device, comprising a frame, a recoating working head disposed on the frame and capable of entering the can body, and driving the recoating working head to move The driving device and the replenishing solution are delivered to the infusion tube on the recoating working head.

Further, the recoating work head includes a first body pushed up and down by the driving device, a second body connected to the first body and driven by the same, and corresponding to the contact point of the inner ear of the inner wall of the can body, the second body The end opposite the contact point of the welding ear is in detachable contact with the contact point of the welding ear, and the infusion tube conveys the replenishing liquid to the end of the second body opposite to the contact point of the welding ear.

Further, the first body and the second body are connected by a connecting rod, and two ends of the connecting rod are respectively hinged with the first body and the second body.

Further, the second body has two and symmetrically arranged, and respectively corresponds to the two soldering ear contact points of the inner wall of the can body.

Further, the moving direction of the second body is substantially horizontal.

Further, the recoating device further comprises a control valve for controlling the infusion volume and the infusion time of the infusion tube to the recoating working head.

Further, the automatic recoating device further includes a conveying device for conveying the can body to the underside of the recoating work head.

Further, the automatic recoating device further includes a top tank cylinder disposed on the frame and located under the recoating work head for pushing the tank to move down.

Due to the adoption of the above technical solution, the invention saves the manual coating 4-6 by adding the recoating device on the welding earphone, and can also adjust the speed of the actual production line, and the recoating device saves the labor by the recoating device. The waste of the replenishing solution is added during the recoating, and the amount of replenishing can be better controlled, so that the product is more uniformly applied without residue.

detailed description

The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings, in which the advantages and features of the invention can be more readily understood by those skilled in the art.

Referring to Figures 1 to 2, the automatic recoating device of the present embodiment includes a frame 1, a recoating working head 4 disposed on the frame 1 and accessible into the can body, and a drive for driving the recoating working head 4 to move. The device 5 delivers the replenishing solution to the infusion tube 6 on the recoating head 4.

The recoating work head 4 includes a first body 7 that is pushed up and down by the driving device 5, a second body 8 connected to the first body 7 and driven by the same, and corresponding to the contact points of the inner ear wall of the can body, the second body The end of the body 8 opposite the contact point of the soldering ear is detachably contacted with the contact point of the soldering ear, and the infusion tube 6 delivers the replenishing liquid to the end of the second body 8 opposite to the contact point of the soldering lug. The second body 8 has two symmetrical arrangements and respectively corresponds to two contact ear contacts of the inner wall of the can body. In a more preferred embodiment, the end of the second body 8 opposite to the contact point of the soldering ear is provided with a recoating head 3 which is made of a flexible material capable of adsorbing liquid, and one end of the infusion tube 6 and the replenishing solution The liquid storage container 10 is connected, and the other end is connected to the recoating head 3, and the replenishing liquid is directly sent to the recoating head 3. When the recoating is applied, the coating can be uniformly applied without scratching the inner wall of the can body.

In this embodiment, the first body 7 and the second body 8 are connected by a connecting rod 9, and the two ends of the connecting rod 9 are respectively hinged with the first body 7 and the second body 8, and the moving direction of the second body 8 is substantially Level. The first body 7 moves downward, pushing the two first bodies 8 to move to the inner wall of the can body respectively, and uniformly applies the replenishing liquid to the inner wall of the can body. When the first body 7 moves upward, the second body 8 moves backwards. The inner wall of the tank is separated and the filling operation is completed.

A control valve 11 is mounted on the infusion tube 6, and the control valve 11 is disposed between the liquid storage container 10 and the refilling working head 4 for controlling the infusion volume and the infusion time of the infusion tube 6 to the refilling working head 4, and controlling the valve 11 The sensing device is connected, and the principle of photoelectric induction is utilized. After each sensing body is sensed, the sensing device automatically opens the control valve 11 for a certain period of time, so as to achieve the effect of injecting a suitable replenishing solution downward, which can achieve The effect of recoating can save the waste of the replenishing solution, and will not cause the replenishing liquid to flow to the can body too much, nor will it drip on the recoating head 3.
