Abstract
Description
Technical Field
[0001] This utility model relates to the field of tableware processing technology, and in particular to a melamine tableware decal device. Background Technology
[0002] Melamine tableware is a thermosetting plastic tableware made from melamine resin through high-temperature molding. It has advantages such as hardness, drop resistance, heat resistance, bright colors, and resistance to deformation, and is widely used in homes, restaurants, schools, and other places. Decal is one of its important decorative techniques, often using dry decals or water transfer decals. Pre-printed patterns are fixed to the surface of the tableware through high-temperature hot pressing or water transfer printing. This not only enhances the product's aesthetics and brand recognition, but also enables personalized and serialized visual designs. It is an important process in melamine products that integrates functionality and artistry.
[0003] In the melamine tableware decal process, the formed tableware blanks must first be placed on a conveyor to enter the decal station. However, since the decals have not yet been applied at this stage, the decal area on the tableware surface is exposed to the air. During the transmission process, problems such as electrostatic adsorption and air disturbance can easily occur due to dust, fibers, or particulate impurities in the environment. This causes dust to adhere to the decal surface, making it impossible for the pattern to fully adhere during the decal process, resulting in quality defects such as bubbles, wrinkles, or peeling, which directly affect the appearance and pass rate of the finished product. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where surface dust on tableware affects the decal application effect.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a melamine tableware decal device, comprising a conveyor for transporting melamine tableware, and further comprising: an electric push rod fixed to the upper part of the conveyor, the electric push rod being electrically connected to the conveyor; when the conveyor drives the tableware to move to the lower part of the electric push rod, the transport stops, and the moving part of the electric push rod moves downward; when the moving part of the electric push rod moves upward, the conveyor starts synchronously; a decal plate fixed to the moving part of the electric push rod, the decal plate being driven downward by the electric push rod to contact the tableware placed on the conveyor and perform a decal action; and a blower assembly disposed on the upper part of the conveyor, the blower assembly including a spray plate for connecting to an air source, the spray plate performing a dust removal action when the moving part of the electric push rod moves upward.
[0006] In at least some embodiments, the electric actuator is fixedly mounted on a support frame fixed to the upper part of the transmitter.

[0009] In at least some embodiments, a groove is provided on one side of the support frame, and the decal board is fixedly connected to a slide plate that is slidably installed inside the groove. The slide plate extends through the groove to the outside and is fixedly connected to a connecting seat.
[0010] In at least some embodiments, the lower part of the movable part of the air cylinder fixed on the upper part of the support frame is fixedly connected to the connecting seat, the spray plate is fixedly installed on one side of the support frame through a support plate, the output end of the air cylinder is connected to the spray plate through an air pipe, when the electric push rod moves upward, the conveyor is started, and the spray plate receives the gas transmitted by the air cylinder to blow and remove dust from the tableware that passes by.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0020] Implementation examples, based on Figures 1-4 ,like Figure 1 As shown in the figure, the melamine tableware decal device provided by this utility model integrates an electric push rod 4 to drive the decal assembly and a synchronous jet dust removal mechanism, thereby realizing automatic dust removal and decal linkage operation before decaling melamine tableware, effectively avoiding decal defects caused by dust, and improving decal quality and production efficiency.
[0021] The system includes a conveyor 1 for transporting melamine tableware. After the tableware is formed, it enters the decal area via the conveyor 1. During normal transport, the conveyor 1 continuously moves the tableware forward. The system also includes an electric push rod 4 fixed to the upper part of the conveyor 1. The electric push rod 4 is electrically connected to the conveyor 1. When the conveyor 1 drives the tableware to the lower part of the electric push rod 4, the transport stops, and the moving part of the electric push rod 4 moves downward. When the moving part of the electric push rod 4 moves upward, the conveyor 1 starts synchronously. A decal plate 5 is fixed to the moving part of the electric push rod 4, and the decal plate 5 is powered by the electric push rod 4. The drive moves downward and contacts the tableware placed on the conveyor 1 to perform the decal action. When the tableware moves to the designated decal position below the electric push rod 4, the conveyor 1 receives an electronic control signal and automatically stops running. The electric push rod 4 starts to move, and its moving part drives the decal plate 5 to move vertically downward, so that the pattern paper on the decal plate 5 is aligned and adhered to the upper surface of the tableware placed on the conveyor 1, completing one pressing action. Subsequently, while the electric push rod 4 drives the decal plate 5 to move upward and reset, the conveyor 1 starts synchronously, ready to convey the next piece of tableware to be decaled.
[0022] The blower assembly 6, located on the upper part of the conveyor 1, is activated in conjunction with the electric push rod 4 during the upward movement of the electric push rod 4 to prevent dust from falling onto the surface of the decal and causing bonding defects. The blower assembly 6 includes a spray plate 602 for connecting to the air source. When the moving part of the electric push rod 4 moves upward, the spray plate 602 performs a jet dust removal action. The blower assembly 6 is composed of a spray plate 602 connected to the air source. Under the electric control drive, compressed air is sprayed downward during the upward movement of the decal plate 5 to perform a short-term directional blowing on the surface of the next piece of tableware that is about to be conveyed to the decal position, removing any dust or particles that may be attached, and preparing a clean surface for the decal.
[0023] Through the precise coordination of this action sequence, an automatic cyclic process of dust removal, decal application, and transmission is achieved, improving the reliability of decal application and the level of automation of the entire production line.
[0024] like Figure 2 , Figure 3 and Figure 4 As shown, in this embodiment, the automatic control of the decal application action is achieved by setting a cooperative structure between the electric push rod 4 and the decal plate 5.
[0025] The support frame 3 fixed on the upper part of the conveyor 1 is fixedly installed with the electric push rod 4. The moving part of the electric push rod 4 is a telescopic shaft. The telescopic shaft of the electric push rod 4 passes through the support frame 3 and is fixedly connected to the decal plate 5 which is slidably installed inside the support frame 3. When the conveyor 1 transmits the tableware to the preset decal position, the electronic control system controls the conveyor 1 to stop running. At the same time, the electric push rod 4 receives the control signal, and its telescopic shaft extends downward, driving the decal plate 5 to move down together. The decal plate 5 is installed inside the support frame 3 by sliding. Its bottom is provided with a decal groove 7 that matches the shape of the tableware, which can accurately place the tableware located in the conveyor belt placement groove 9. After the decaling action is completed, the electric push rod 4 retracts, and the decal plate 5 rises and resets, completing one cycle of decaling operation.
[0026] A motor 2 is fixedly installed on one side of the conveyor 1. The output end of the motor 2 is fixedly connected to the drive shaft of the conveyor 1. The conveyor 1 is driven by the motor 2 installed on one side. The output shaft of the motor 2 is fixedly connected to the transmission shaft of the conveyor 1, which drives the conveyor belt to rotate. The upper part of the conveyor belt of the conveyor 1 is provided with a placement groove 9 for placing tableware. The decal plate 5 is provided with a decal groove 7 that matches the shape of the tableware. The placement groove 9 on the conveyor belt can stably position the melamine tableware and prevent positional displacement during the transmission or decaling process. This structural design achieves efficient and precise decaling function through electronic control linkage, which significantly improves the consistency and automation level of melamine tableware decals.
[0027] like Figure 2 and Figure 3 As shown, in this embodiment, in order to achieve the surface dust removal function before decal application, a sliding guide and blower assembly 6 linkage structure is designed on one side of the support frame 3 of the decal device.
[0028] A groove 8 is provided on one side of the support frame 3. The decal board 5 is fixedly connected to a slide plate 606 that is slidably installed inside the groove 8, so that the decal board 5 maintains vertical guidance and smooth sliding when it performs the decal application under the drive of the electric actuator 4. The slide plate 606 extends through the groove 8 to the outside and is fixedly connected to a connecting seat 605. The lower part of the movable part of the air cylinder 604, which is fixed to the upper part of the support frame 3, is fixedly connected to the connecting seat 605. A spray plate 602 is fixedly installed on one side of the support frame 3 through a support plate 601. The output end of the air cylinder 604... The air pipe 603 is connected to the spray plate 602. When the electric push rod 4 moves upward, the conveyor 1 is started, and the spray plate 602 receives the gas transmitted by the air cylinder 604 to blow and remove dust from the tableware that passes by. After the decal application is completed, during the process of the electric push rod 4 driving the decal plate 5 to move upward and reset, the air cylinder 604 simultaneously drives the spray plate 602 to start the jet action. That is, after the spray plate 602 receives the compressed gas output by the air cylinder 604, it blows downward to briefly remove dust from the next piece of tableware that is about to enter the decal position.
[0029] During this process, the conveyor 1 operates synchronously, and the tableware moves forward continuously, completing the automatic cycle of decal application, upward movement, dust removal, and feeding. This design combines the up and down stroke of the decal application action with the reasonable embedding of the dust removal action, making full use of the structural linkage relationship. This ensures that dust removal before decal application does not increase the additional time cost, while significantly reducing the probability of dust particles affecting the adhesion quality of the pattern, further improving the overall production yield and automation level.
[0030] The working principle of this utility model is as follows: The melamine tableware decal device provided by this utility model achieves coordinated control of the decal application and dust removal actions by setting an electric push rod 4, a decal plate 5, and a blower assembly 6 on the conveyor 1. When the conveyor 1 transports the tableware to the preset decal position, the electronic control system stops the conveyor 1. The electric push rod 4 drives the decal plate 5 to move vertically downward to complete the decal application. Then, while the electric push rod 4 returns to its original position, the air cylinder 604 and the spray plate 602 located on the support frame 3 are linked to perform a jet dust removal operation, which blows the next piece of tableware that is about to enter the decal position to remove dust from its surface. Throughout the process, the decal plate 5 is guided and slid by the slide groove 8 to maintain stable alignment. The spray plate 602 is supplied with air by the air cylinder 604 through the air pipe 603 to complete directional blowing. After the decal application is completed, the conveyor 1 is restarted to send out the decaled tableware, and the next piece of tableware enters the decal position, thereby realizing a continuous automatic cycle of decal application, dust removal, and transmission, which significantly improves the accuracy, cleanliness, and production efficiency of decal application.
[0031] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
