Description

Technical Field

[0001] This utility model relates to the field of aluminum can production equipment, and in particular to a spraying device for aluminum can production. Background Technology

[0002] During the aluminum can production process, a spraying device is used to spray the area around the aluminum can to form a protective film on the outer wall of the can, thereby protecting the area around the can and increasing its service life.

[0003] When aluminum cans are used for heat dissipation (such as heat dissipation shells for electronic devices) or need to be used as conductive components (such as electromagnetic shielding containers), it is not necessary to coat the entire outer wall of the aluminum can with a coating. Otherwise, it will affect the heat dissipation efficiency of the metal or damage its conductivity, and it will also waste the coating and increase production costs.

[0004] In the prior art, when spraying aluminum cans, the spraying device applicable to the above situation generally needs to position the aluminum can first, and then spray specific parts of the aluminum can with a spray gun. This may result in incomplete spraying of specific parts, poor uniformity of spraying, and reduced spraying efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a spraying device for aluminum can production that can perform comprehensive spraying on specific parts, improve the uniformity of spraying and the efficiency of spraying.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A spraying device for aluminum can production includes a support frame, a clamping mechanism, and two spraying mechanisms. The clamping mechanism includes two clamping plates arranged parallel to each other on the support frame, forming a clamping area for holding the aluminum can. The two spraying mechanisms are vertically mounted on the support frame. Each spraying mechanism includes a mounting frame, a spray box, a motor, a lead screw, a slider, a connecting pipe, and multiple nozzles. The mounting frame is mounted on the support frame, the lead screw is mounted on the mounting frame, and the slider is mounted on the lead screw. The connecting pipe has an inlet and multiple outlets. The inlet communicates with the spray box. Each outlet has a nozzle facing the clamping area. The motor is mounted on the mounting frame and is connected to the lead screw. The motor drives the lead screw to rotate, causing the slider and nozzles to move up and down along the axis of the lead screw to perform comprehensive spraying on specific areas of the aluminum can.

[0008] Furthermore, the clamping mechanism also includes a motor, a first screw, a second screw, a belt, a drive wheel, and a driven wheel. The first screw and the second screw are arranged parallel to each other on the bracket, and the two clamping plates are arranged parallel to each other on the first screw and the second screw. The axial direction of the first screw is perpendicular to the length direction of the clamping plate. The drive wheel is installed at one end of the first screw, and the driven wheel is installed at one end of the second screw. The belt is wound around the drive wheel and the driven wheel. The motor drives the drive wheel and the first screw to rotate and drives the driven wheel and the second screw to rotate, thereby adjusting the distance between the two clamping plates to accommodate aluminum cans of different sizes.

[0009] Furthermore, the clamping plate is provided with a clamping part, which matches the outer wall of the aluminum can, and the clamping area is formed between two opposite clamping parts.

[0010] Furthermore, the mounting frame includes a vertical plate and a horizontal plate. The vertical plate is vertically mounted on the bracket, the lead screw is mounted on the vertical plate, the horizontal plate is perpendicularly connected to the vertical plate, and the spray box and motor are both mounted on the horizontal plate.

[0011] Furthermore, the slider includes a sliding plate and a mounting plate. The sliding plate is mounted on the lead screw and located on the vertical plate. The mounting plate is fixedly connected to the sliding plate. A plurality of nozzles are equidistantly spaced on the mounting plate along its length.

[0012] Furthermore, the spraying mechanism also includes a control valve, which is disposed on the spray box to control the on / off state of the connecting pipe.

[0023] Figures 1-3 The present invention relates to a spraying device for aluminum can production, comprising a support 10, a clamping mechanism 20, and two spraying mechanisms 30.

[0024] In this embodiment:

[0025] The clamping mechanism 20 includes a motor 21, a first screw 22, a second screw 23, a belt 25, a drive wheel 26, a driven wheel 27, and two clamping plates 24.

[0026] The clamping plate 24 is provided with a clamping part 241, which matches the outer wall of the aluminum can, and a clamping area for clamping the aluminum can is formed between two opposing clamping parts 241.

[0027] The first screw 22 and the second screw 23 are arranged parallel to each other on the bracket 10. Two clamping plates 24 are arranged parallel to each other on the first screw 22 and the second screw 23. The axial direction of the first screw 22 is perpendicular to the length direction of the clamping plate 24. The driving wheel 26 is installed at one end of the first screw 22, and the driven wheel 27 is installed at one end of the second screw 23. The belt 25 is wound around the driving wheel 26 and the driven wheel 27. The motor 37 drives the driving wheel 26 and the first screw 22 to rotate and drives the driven wheel 27 and the second screw 23 to rotate, thereby adjusting the distance between the two clamping plates 24 to accommodate aluminum cans of different sizes, with a wide range of applications.

[0028] Two spraying mechanisms 30 are vertically mounted on the bracket 10. Each spraying mechanism 30 includes a mounting frame 31, a spray box 32, a motor 37, a lead screw 33, a slider 34, a connecting pipe 35, multiple spray nozzles 36, and a control valve 38.

[0029] Mounting bracket 31 includes a vertical plate 311 and a horizontal plate 312. The vertical plate 311 is vertically mounted on the bracket 10, the lead screw 33 is mounted on the vertical plate 311, and the horizontal plate 312 is vertically connected to the vertical plate 311. The spray box 32 and the motor 37 are both mounted on the horizontal plate 312.

[0030] The lead screw 33 is mounted on the mounting bracket 31. The slider 34 includes a slide plate 341 and a mounting plate 342. The slide plate 341 is mounted on the lead screw 33 and located on the vertical plate 311. The mounting plate 342 is fixedly connected to the slide plate 341 and is used to install multiple nozzles 36.

[0031] The connecting pipe 35 has an inlet and multiple outlets. The inlet is connected to the spray box 32. A nozzle 36 is installed at each outlet. The multiple nozzles 36 are equidistantly arranged on the mounting plate 342 along its length, with the nozzles 36 facing the clamping area.

[0032] The motor 37 is mounted on the mounting bracket 31 and is connected to the lead screw 33 for transmission. The motor 37 drives the lead screw 33 to rotate, thereby driving the slider 34 and the spray head 36 to move up and down along the axis of the lead screw 33 to perform full spraying on specific parts of the aluminum can.

[0033] The control valve 38 is installed on the spray box 32 to control the opening and closing of the connecting pipe 35.

[0034] In use, this application first uses two clamping plates 24 to hold the parts of the aluminum can that do not need to be painted, thus positioning the aluminum can. Then, the operator starts the painting mechanism 30, and the paint in the paint tank is sprayed out from multiple nozzles 36 along the connecting pipe 35, achieving painting of specific parts of the aluminum can. Furthermore, the nozzles 36 can be raised and lowered via the lead screw 33 and slider 34, resulting in more comprehensive and uniform painting and improved painting efficiency. In this application, the motor 37 drives the drive wheel 26 and the first screw 22 to rotate, which in turn drives the driven wheel 27 and the second screw 23 to rotate, thereby adjusting the distance between the two clamping plates 24 to accommodate aluminum cans of different sizes, thus having a wide range of applications.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
