Description

Technical Field

[0001] This application relates to the field of electrophoretic coating, specifically to a high-efficiency and energy-saving electrophoretic coating equipment. Background Technology

[0002] Electrophoretic coating is a coating method that uses an external electric field to cause pigment and resin particles suspended in an electrophoretic solution to migrate directionally and deposit onto a substrate surface. It features water solubility, non-toxicity, and a high degree of automation. The paint film formed by electrophoretic coating has the advantages of being full, uniform, smooth, and even. The hardness, adhesion, corrosion resistance, impact resistance, and penetration performance of electrophoretic paint films are significantly superior to other coating processes. Due to its excellent qualities and high environmental friendliness, it is gradually replacing traditional paint spraying.

[0003] In existing related technologies, when a workpiece is subjected to electrophoretic coating, it needs to be immersed in a degreasing tank, a phosphating tank and an electrophoretic tank in sequence, and it also needs to undergo multiple water washing operations in order to improve the quality of the paint film.

[0004] When a workpiece is immersed and processed in one tank and moves toward another tank, the surface of the workpiece and the lifting device carries a large amount of processing or cleaning fluid. If it enters the next tank directly, it will contaminate the processing fluid in the next tank. If it stays for a while before entering the next tank, it will reduce the overall coating efficiency. Utility Model Content

[0005] In order to overcome the problem in the prior art that the treatment liquid on the workpiece surface will cause cross-contamination and affect the film formation effect or coating efficiency, this application provides a high-efficiency and energy-saving electrophoretic coating equipment.

[0006] This application adopts the following technical solution: a high-efficiency and energy-saving electrophoretic coating equipment, comprising: a slide rail, with a crossbeam provided between a pair of slide rails, the crossbeam being slidable on the slide rail; a treatment tank, a plurality of treatment tanks being provided below the slide rails and spaced apart along the sliding direction of the crossbeam; a movable beam, one of the movable beams being provided below the crossbeam and connected to the crossbeam via a linear drive mechanism, the bottom center of the movable beam being provided with a hanger for hanging workpieces, and the bottom sides of the movable beam being provided with air blowers for blowing the hanger.

[0007] Optionally, the linear drive mechanism is used to drive the movable beam to reciprocate in the vertical direction.

[0008] Optionally, the bracket is provided with a plurality of hanging rods, the hanging rods are wavy and extend horizontally, and a plurality of air blowers are spaced apart along the length of the movable beam.

[0009] Optionally, each of the processing tanks is fitted with a liquid collection tank on its outer side, and a cavity is formed between the inner wall of the liquid collection tank and the outer wall of the processing tank; the movable beam is provided with a surrounding plate, and the four surrounding plates are arranged in a rectangular pattern, surrounding the movable beam and the hanging frame; when the hanging frame is lowered into the processing tank, the surrounding plate moves into the cavity.

[0010] Optionally, a pair of sidewalls along the length of the movable beam are provided with support rods and first electric push rods. The support rods extend horizontally, and the two enclosure panels are respectively and correspondingly installed on the support rods. The first electric push rods are used to push the enclosure panels connected to the support rods. A pair of second electric push rods are provided at the bottom of the movable beam, and both of the second electric push rods point to the ends of the movable beam. The remaining two enclosure panels are respectively and correspondingly installed on the second electric push rods.

[0011] Optionally, the enclosure plate connected to the support rod is parallel to the side wall along the length of the movable beam, and the enclosure plate connected to the second electric push rod is parallel to the side wall along the width of the movable beam.

[0012] Optionally, the first electric push rod and the corresponding enclosure plate, as well as the second electric push rod and the corresponding enclosure plate, are all connected by bolts.

[0013] Optionally, two adjacent enclosure panels are separated from each other and connected by a plurality of elastic ropes, which are spaced apart along the height direction of the enclosure panels.

[0014] Compared with the prior art, this application has the following advantages:

[0015] 1. By setting several air blowers at the bottom of the movable beam and on both sides of the hanger, and distributing the air blowers in two rows, the air blowers can effectively remove the treatment liquid carried on the surface of the hanger and the workpiece, and prevent different treatment liquids from mixing and affecting the treatment effect.

[0016] 2. By setting four rectangular partitions on the outside of the movable beam, the hanging rack, workpiece, and air blower are shielded, thus preventing the treatment fluid blown away by the air blower from splashing everywhere. At the same time, a collection tank is set on the outside of the treatment tank to collect the blown-away treatment fluid and to store the partitions, shortening the settling time of the workpiece before entering the next treatment tank and effectively improving the coating efficiency.

[0022] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] like Figures 1-4 As shown, the high-efficiency and energy-saving electrophoretic coating equipment includes a slide rail 1, a treatment tank 2, a movable beam 3, and a crossbeam 10. A pair of slide rails 1 are arranged in parallel, and the crossbeam 10 is positioned between the two slide rails 1. A mechanism such as a traveling motor can be installed on the crossbeam 10 to allow it to slide between the two slide rails 1. Simultaneously, a linear drive mechanism 31 is provided between the crossbeam 10 and the movable beam 3, allowing the movable beam 3 to move synchronously along the length of the slide rail 1 along the crossbeam 10, and also to reciprocate vertically. The linear drive mechanism 31 can be a hydraulic cylinder, a pneumatic cylinder, or a linear slide table, as long as it can perform the above actions. Several treatment tanks 2 are positioned below the slide rails 1 and the movable beam 3, and are spaced apart along the length of the slide rails 1. Thus, with the cooperation of the crossbeam 10 and the linear drive mechanism 31, the movable beam 3 can pass sequentially over the several treatment tanks 2 and move towards the tanks 2.

[0024] A hanger 4 is provided at the bottom of the movable beam 3, and several hanging rods 40 are provided on the hanger 4. The hanging rods 40 are wavy and extend horizontally. Each hanging rod 40 can hang a workpiece, which increases the number of workpieces that can be hung on the hanger 4, thereby increasing the number of workpieces that can be electrophoretically coated in a single operation, thus improving coating efficiency. The hanger 4 is located at the center of the bottom of the movable beam 3. Several air blowers 5 are also provided on both sides of the bottom of the movable beam 3. The air blowers 5 are arranged in a straight line at the bottom of the movable beam 3. That is to say, there are two rows of air blowers 5 on both sides of the bottom of the movable beam 3. An air pump can be placed on the crossbeam 10 or the movable beam 3 to supply air to the air blowers 5. In this way, the air blowers 5 can spray air downwards, thereby blowing away the treatment liquid carried on the surface of the workpiece.

[0025] Each of the processing tanks 2 is fitted with a liquid collection tank 6 on its outer side. A cavity 60 is formed between the inner wall of the liquid collection tank 6 and the outer wall of the processing tank 2, meaning that the outer diameter of the liquid collection tank 6 is larger than the outer diameter of the processing tank 2. The movable beam 3 has two pairs of side walls. One pair of side walls extends along the length direction of the movable beam 3, and the other pair of side walls extends along the width direction of the movable beam 3. Support rods 32 are provided on each pair of side walls along the length direction of the movable beam 3. Two support rods 32 can be provided on each side wall. A surrounding plate 7 is provided on each of the two support rods 32 on the same side. In this way, the outer side of the movable beam 3 has two surrounding plates 7 that are parallel to the side walls along the length direction of the movable beam 3. Furthermore, a first electric push rod 33 is provided in the middle of each of the two side walls. The first electric push rod 33 is located between the two support rods 32, and the first electric push rod 33 is connected to the corresponding enclosure 7 by bolts 330. In this way, under the push of the first electric push rod 33, the enclosure 7 can slide on the support rod 32. That is to say, the corresponding enclosure 7 can move closer to or away from the side wall in the length direction of the movable beam 3.

[0026] At both ends of the bottom of the movable beam 3, there is a second electric push rod 34. Both second electric push rods 34 point towards the end of the movable beam 3 and extend and retract along the length of the movable beam 3. Below the movable beam 3, there are also two surrounding plates 7. These two surrounding plates 7 are parallel to the sidewalls of the movable beam 3 in the width direction and are connected to the second electric push rods 34 by bolts 330. In this way, the four surrounding plates 7 are arranged in a similar rectangular shape, and adjacent surrounding plates 7 are connected by several elastic ropes 70. These elastic ropes 70 are spaced apart along the height direction of the surrounding plates 7. Under the action of the second electric push rods 34, the corresponding surrounding plates 7 can move closer to or further away from the sidewalls of the movable beam 3 in the width direction.

[0027] The first electric push rod 33 and the second electric push rod 34 drive the four enclosure plates 7, enabling fine-tuning of the distance between them and thus the size of the space enclosed by the four enclosure plates 7. The hanger 4 and hanger rod 40 are both located inside the four enclosure plates 7, ensuring that the workpiece does not contact the enclosure plates 7 after being hung. When the hanger 4 and the workpiece are immersed in the treatment liquid in the treatment tank 2, the four enclosure plates 7 are fitted into the cavity 60, meaning they are located between the outer wall of the treatment tank 2 and the inner wall of the collection tank 6, ensuring that the arrangement of the enclosure plates 7 does not affect the normal processing of the workpiece. When the workpiece is processed and moved above the liquid surface in the processing tank 2, the air blower 5 begins to blow air towards the hanger 4 and the workpiece. At this time, under the cover of the four enclosure plates 7, the blown-out processing liquid will not splash everywhere, and can drip into the corresponding processing tank 2 or collection tank 6 after hitting the enclosure plates 7. This effectively prevents the pollution problem caused by the mixing of different processing liquids, and minimizes the standing time of the workpiece before entering the next processing tank 2, effectively improving the coating efficiency. Furthermore, the elastic rope 70 can easily fix the enclosure plates 7, preventing the air blower 5 from blowing the enclosure plates 7 away or overturning them when blowing air. At the same time, the elastic extension and contraction of the elastic rope 70 will not affect the adjustment of the position of the enclosure plates 7. Moreover, by increasing the density of the elastic rope 70 or replacing the elastic rope 70 with an elastic mesh, it is possible to prevent the processing liquid from flying out from the gap between two adjacent enclosure plates 7.

[0028] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
