Description

Technical Field

[0001] This utility model relates to spray curing, and in particular to an electron beam spray curing device. Background Technology

[0002] In the spraying process of workpieces, there is an existing electron beam spraying and curing device. This device has a spraying chamber, and the spraying equipment and electron beam curing equipment are installed inside the spraying chamber. The workpiece is sprayed, and after spraying, the electron beam curing equipment outputs an electron beam that acts on the coating on the workpiece surface, causing the coating to cure rapidly. However, because the electron beam can react with oxygen in the air, producing ozone, which is harmful to humans, the spraying chamber needs to be sealed during the spraying and curing process to prevent ozone leakage. This means that during the spraying and curing process, the workpiece to be sprayed cannot continuously enter the spraying chamber, and the sprayed workpiece cannot continuously leave the spraying chamber, resulting in low spraying efficiency and limiting its widespread application. Utility Model Content

[0003] The purpose of this invention is to solve the problem of low efficiency in preventing ozone generation mentioned in the background art, and to design an electron beam spray curing device.

[0004] To achieve the above objectives, the technical solution of this utility model is an electron beam spraying and curing device, comprising a conveying device, an electron beam housing, an automatic spraying nozzle, an electron beam lamp, a feeding pipe, and a photoelectric sensor. The electron beam housing is installed on the upper part of the conveying device, and a feeding pipe is installed at the front end inside the electron beam housing. An automatic spraying nozzle is connected to the lower end of the feeding pipe, and a photoelectric sensor is installed at the front end of the automatic spraying nozzle. An electron beam lamp is installed at the rear end inside the electron beam housing.

[0005] Furthermore, a bracket is installed at the lower end of the conveying device, and a roller is installed at each end of the bracket. A motor is installed below the roller, and the crown gear on the motor is perpendicularly connected to the spur gear on the roller. A conveyor belt is fitted around the roller, and a product fixing module is installed above the conveyor belt.

[0006] Furthermore, a cleaning device is installed at the front end of the conveying device, with a dust suction port at the lower front end of the cleaning device, a cleaning net installed at the upper inside of the cleaning device, a centrifugal fan installed at the upper outside of the cleaning device, and a valve at the lower rear end of the cleaning device.

[0007] Furthermore, the electron beam lamp is installed in the middle of the isolation cover, and a blower is connected to the outside of the isolation cover. The rear end of the blower is connected to a nitrogen pipe.

[0008] Furthermore, the automatic spray nozzle has a feed inlet in the middle, and a first air inlet and a second air inlet on each side of the automatic spray nozzle.

[0009] Beneficial effects:

[0010] This invention provides an electron beam spraying curing device with the following advantages: Through its structural design, the device utilizes the rotation of a centrifugal fan to draw air from inside the cleaning device to the outside, creating a momentary vacuum inside. Since the external atmospheric pressure is higher than the internal atmospheric pressure, suction is generated inside the cleaning device, drawing dust in through the suction port. The cleaning screen inside the device retains the dust, which can then be discharged through a valve at the bottom, keeping the product clean and allowing the coating to adhere better to the product surface. An automatic spray nozzle is connected to the material conveyor. The tube and photoelectric sensor can emit laser irradiation, receive the signal through diffuse reflection, convert the light signal into an electrical signal, calculate the distance, and detect whether the product has been delivered to the correct position. When the product is delivered to the correct position and the laser irradiation distance reaches the set value, the photoelectric sensor will emit an electrical signal, and the automatic spraying nozzle will spray the product. The blower guides nitrogen gas to generate an airflow from inside the electron beam chamber to the outside of the electron beam chamber. This prevents oxygen from outside the electron beam chamber from flowing into the electron beam chamber, thus preventing contact between the electron beam and oxygen during the curing process and the generation of ozone that is harmful to the body. This utility model does not require operation in a vacuum environment and can operate continuously to improve production efficiency. Attached Figure Description

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "set / set up," "sleeve," "connection," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Please see Figure 1-5 This utility model provides a technical solution: an electron beam spraying and curing device, including a conveying device 1, an electron beam housing 2, a paint nozzle 3, a material conveying pipe 6, a photoelectric sensor 18, and an electron beam lamp 4. The electron beam housing 2 is installed on the upper part of the conveying device 1. The material conveying pipe 6 is installed at the front end inside the electron beam housing 2. The lower end of the material conveying pipe 6 is connected to an automatic spraying nozzle 3. The photoelectric sensor 18 is installed at the front end of the automatic spraying nozzle. The electron beam lamp 4 is installed at the rear end inside the electron beam housing 2.

[0021] In this utility model, a bracket 22 is installed at the lower end of the conveying device 1, and a roller 19 is installed at each end of the bracket 22. The roller 19 is fitted with a conveyor belt 21, and a product fixing module is installed above the conveyor belt 21. The roller 22 is connected to the crown gear on the motor 20 through its own spur gear. The power is transmitted to the roller to rotate through the vertical gear connection. The roller drives the conveyor belt to move through friction, so that the products can automatically flow into the production line.

[0022] In this utility model, a cleaning device 7 is installed at the front end of the conveying device 1. The front end of the lower part of the cleaning device 7 has a dust suction port 13. A cleaning net 15 is installed at the upper end inside the cleaning device. A centrifugal fan 16 is installed at the upper end outside the cleaning device 7. A valve 17 is installed at the rear end of the lower part of the cleaning device 7. Keeping the product clean allows the coating to adhere better to the product surface.

[0023] In this invention, the electron beam lamp 4 is installed in the middle of the isolation cover 8, and the rear end of the blower 5 is connected to the nitrogen pipe 9. The blower guides the nitrogen to generate an airflow from inside the electron beam box to outside the electron beam box. In this way, oxygen outside the electron beam box cannot flow into the electron beam box, preventing contact between the electron beam and oxygen during the curing process and the generation of ozone that is harmful to the body.

[0024] In this invention, the automatic spray nozzle 3 has a feed inlet in the middle and a first air inlet 11 and a second air inlet 12 on each side, so that the sprayed paint is atomized and evenly sprayed onto the product surface.

[0025] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0026] In this implementation plan:

[0027] First, power on this utility model, turn on the PLC control system, start the conveyor device, and let the motor on the conveyor device transmit power to the spur gear on the roller through the crown gear on the motor, drive the roller to rotate, and the roller drives the conveyor belt to convey the product through friction.

[0028] When the cleaning device is activated, the centrifugal fan inside the device draws air out, creating a momentary vacuum inside. Since the outside atmospheric pressure is higher than the inside atmospheric pressure, suction is generated inside the device, drawing dust in through the suction port. The cleaning screen inside the device retains the dust, which can then be discharged through the valve at the bottom of the device.

[0029] When the automatic spraying device is started, the photoelectric sensor can emit laser irradiation, receive the signal through diffuse reflection, convert the light signal into an electrical signal, calculate the distance, and detect whether the product has been delivered to the correct position. When the product is delivered to the correct position and the laser irradiation distance reaches the set value, the photoelectric sensor will send an electrical signal to the automatic spraying nozzle to spray the paint onto the product. Then, the product is conveyed to the isolation hood by the conveying device, where the paint is cured by the electron beam lamp.

[0030] Start the blower to deliver nitrogen into the isolation chamber, creating an airflow from inside the electron beam chamber to the outside. This prevents oxygen from the outside air from flowing into the electron beam chamber, while the airflow generated by the nitrogen also effectively cools the cured product.

[0031] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
