Description

Technical Field

[0001] The present invention particularly relates to a multi-channel queue cleaning device. Background Art

[0002] Powder spraying is the process of using corona discharge to adsorb powder coating onto workpieces. Powder spraying, also known as powder coating, is a new type of coating process that has developed rapidly in recent decades. The raw material used is plastic powder. When powder is applied to steel workpieces, the steel is isolated from air and water, thereby preventing steel from rusting and increasing the practical life of steel.

[0003] At present, semi-finished workpieces are often contaminated with oil, rust and other oxidized layers during processing, factory storage or transportation. These oil, oxidized layers, dust, fingerprints of operators and other pollutants not only affect the adhesion of the decorative coating layer on the surface of the product, but also cause particles and bubbles in the coating layer, and even cause the coating layer to fall off in pieces. Therefore, pre-treatment is a necessary process before coating processing. The conventional pre-treatment process is cleaning, which uses chemicals and clean water to clean the semi-finished workpiece to remove pollutants on the surface of the workpiece.

[0004] However, most of the existing workpiece cleaning and conveying methods use mesh belt conveying, suspended chain mesh belt conveying or roller conveying, which are used to automatically send the workpiece to be cleaned into the cleaning area for spray cleaning. The suspended chain conveying is only suitable for workpieces with specific hanging conditions and has a narrow scope of application. The general workpiece cleaning and conveying uses mesh belt conveying or roller conveying. When the above two methods are used, the cleaning spray water is easy to contaminate the chain sprocket of the conveying transmission, which can easily cause the chain to be damp and rusted for a long time, affecting subsequent use and accelerating damage.

[0033] The following specific implementation contents provide a variety of different embodiments or examples for implementing the present invention. Of course, these are only embodiments or examples and do not wish to be restrictive.

[0034] like Figure 1-Figure 7A multi-channel queue cleaning device shown in the figure comprises: a frame 1; a plurality of groups of conveying channels, which are arranged on the frame 1 and are evenly spaced and arranged along the same axial direction, and each group of conveying channels comprises two conveying chains 2 arranged at intervals and a plurality of carriers 3 connected between the two conveying chains 2; a plurality of carriers 4, which are respectively arranged on the carriers 3 in a one-to-one correspondence and can move up and down relative to the carriers 3, and each carrier 4 has a cavity 5 with an upper opening, in which a plurality of support rods 6 are arranged at intervals, and a workpiece positioning area is formed between the plurality of support rods 6; a lifting device, which is arranged on the frame 1 and is located below the carrier 4, It includes a top plate 7 and a cylinder 8 for driving the top plate 7 to move up and down, and the top plate 7 can move up and down to abut against the carrier 4; a spraying device, which is arranged on the frame 1 and is located correspondingly directly above the jacking device, includes a water tank 9 and a plurality of spray pipes 10 connected to the water tank 9, and a driving component 11 for driving the plurality of spray pipes 10 to rotate; wherein the spray pipe 10 is rotatably arranged below the water tank 9 through a water pipe rotating joint, and the lower end of the spray pipe 10 is connected to a spray box 12, and the spray box 12 is evenly distributed with a plurality of nozzles 13 along the circumference, and the nozzle of each nozzle 13 is facing below the center of the spray box 12.

[0035] Specifically, the workpiece is a cooker, and the bottom surface of the cooker is a spherical arc surface. The workpieces to be cleaned are placed in the carrier one by one, and a plurality of support rods in the carrier are supported along the circumference of the workpiece to support the lower side of the workpiece, so that the cooker is positioned and suspended in the carrier cavity. When the workpiece is sprayed, the water after the spraying and cleaning will be stored in the carrier cavity and will not flow to the conveying channel conveying chain, so that the conveying chain can be kept dry for a long time.

[0036] The carrier can move up and down relative to the carrier plate on the conveyor chain, and then through the cooperation of the jacking device and the spraying device, when the jacking device drives the carrier to move up and down relative to the carrier plate, the driving component of the spraying device drives the spray pipe to rotate, and then the nozzle on the spray box rotates accordingly, thereby realizing multi-directional spraying and flushing of the carrier and the workpiece.

[0037] Furthermore, a first drain pipe 41 connected to the cavity 5 is provided at the lower end of the carrier 4, and an electric valve 42 and a position switch 43 are respectively provided on the first drain pipe 41; a second drain pipe 44 is provided on the top plate 7 corresponding to the first drain pipe 41; the lower end of the second drain pipe 44 is connected to a transversely arranged third drain pipe 45; a recovery box 46 with an upper opening is provided on the frame 1, and one end of the third drain pipe 45 is located directly above the opening of the recovery box 46; the second drain pipe 44 can be displaced upward with the top plate 7 and sleeved on the lower end of the first drain pipe 41; when the lower end of the first drain pipe 41 is located in the second drain pipe 44, the position switch 43 can be triggered to control the opening of the electric valve 42 through an external controller.

[0038] Specifically, in the initial state, the electric valve on the first drain pipe is in a closed state, and then the cavity of the carrier is in a storage state capable of storing clean water. When the top plate in the jacking device is driven by the cylinder to move upward, the second drain pipe on the top plate can move upward to cover the lower end of the first drain pipe under the carrier, and then the position switch on the first drain pipe is triggered when covered by the second drain pipe, and an electrical signal is sent to control the electric valve on the first drain pipe to open. Then, when the carrier is lifted and moved up and down to receive the spray water, the spray water in the carrier can be transported to the recovery box for collection through the first drain pipe, the second drain pipe and the third drain pipe in turn, thereby effectively avoiding the problem of clean water being contaminated by the conveyor chain and causing the long-term moisture of the conveyor chain to aggravate damage. In addition, the timely drainage of the carrier is convenient for the subsequent addition of multiple spray cleaning devices for spray cleaning, so as to meet the cleaning requirements of semi-finished workpieces using different chemical agents and clean water.

[0039] Furthermore, the driving member 11 includes a plurality of transmission sprockets 21 and a driving sprocket 22, and a motor 23 for driving the driving sprocket 22 to rotate. The plurality of transmission sprockets 21 are arranged on the spray pipe 10 in a one-to-one correspondence, and a chain 24 is connected between the plurality of transmission sprockets 21 and the driving sprocket 22. Then, the driving sprocket is driven by the motor to rotate, so that the plurality of transmission sprockets are driven to rotate through the chain, so as to realize the rotation of the plurality of spray pipes.

[0040] Furthermore, the frame 1 is provided with pressure plates 31 on both sides of each group of conveying channels, and push rods 32 are movably inserted on both sides of the carrier 4. The two push rods 32 can move relatively close to or away from each other. The frame 1 is provided with an adjusting component 33 that can drive the two pressure plates 31 to move relatively close to or away from each other. The pressure plates 31 can be displaced one by one to abut against one end of the push rods 32, so that the two push rods 32 move relatively close to each other to clamp the workpiece.

[0041] Specifically, the pressure plates on both sides of each group of conveying channels are pressed against the push rods one by one, so that the push rods on both sides of the carrier are relatively moved closer, so that the push rods can clamp and fix the workpieces in the carrier, and the distance between the pressure plates on both sides of the same conveying channel can be adjusted by the adjusting component, so as to meet the clamping and pressing positioning requirements of different workpiece widths.

[0042] Furthermore, the adjusting member 33 includes a guide shaft 34 and a plurality of screw rods 35 respectively arranged on the frame 1, wherein the screw rod 35 is rotatably arranged on the frame 1, and the pressure plate 31 is movably sleeved on the guide shaft 34 through a linear bearing, and the ends of the plurality of screw rods 35 are respectively provided with transmission gears 36, and adjacent transmission gears 36 are meshed with each other, and the screw rod 35 has a first thread segment and a second thread segment respectively, and the thread rotation direction of the first thread segment is opposite to the thread rotation direction of the second thread segment, and the pressure plates 31 on both sides of the same conveying channel are respectively threadedly sleeved on the first thread segment and the second thread segment in a one-to-one corresponding manner.

[0043] Specifically, the transmission gears between the screws are used to transmit the information to each other, so that the user can turn one of the screws to drive all the screws to rotate through the transmission gears. Since the thread rotation directions of the first thread segment and the second thread segment on the screw are opposite, the pressure plates respectively located on the first thread segment and the second thread segment can be adjusted to move relatively closer or farther along the guide shaft as the screw rotates.

[0044] Furthermore, the pressing plate 31 includes a straight plate 37 arranged parallel to the conveying direction of the conveyor chain 2, and inclined guide plates 38 respectively arranged at both ends of the straight plate 37, and a vertical plate 39 is arranged on the straight plate 37 corresponding to the position of the jacking device. When one end of the ejector rod is displaced and abuts against the inclined guide plate driven by the conveyor chain, the ejector rods on both sides of the carrier are respectively displaced toward the center of the workpiece through the guidance of the inclined guide plate, and when the ejector rod abuts against the straight plate, the ejector rod is in a clamping state of clamping and pressing the workpiece.

[0045] Furthermore, a ball 30 is movably embedded on one end of the push rod 32 for contacting with the pressure plate 31, and a rubber sleeve 40 is provided on one end of the push rod 32 for contacting with the workpiece. The ball can reduce the friction force when contacting with the pressure plate, thereby reducing wear, and the rubber sleeve can increase the friction force between the cavity and the workpiece, thereby increasing the firmness of the workpiece clamping.

[0046] Furthermore, the push rod 32 is provided with a first flange 51 and a second flange 52 at intervals, the first flange 51 is located in the cavity 5, the second flange 52 is located outside the carrier 4, and a spring 53 is abutted between the second flange 52 and the carrier 4 on the push rod 32, and the two push rods 32 are initially in a relatively distant active state through the spring 53. Then, when the push rod is disengaged from the straight plate abutment in the pressure plate as the conveyor chain moves, the elastic force of the spring can automatically release the clamping and positioning of the workpiece.

[0047] Furthermore, a plurality of the spraying devices and the lifting devices are arranged at intervals along the conveying direction of the conveying chain 2. Different spraying devices spray different medicines or clean water to meet the multi-station spray cleaning.

[0048] In conjunction with the drawings and the above, the basic principles and main features of the present invention and the advantages of the present invention are shown and described. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
