Description

Technical Field

[0001] This utility model relates to the field of melamine tableware molding technology, and specifically to a cleaning device for melamine tableware molding. Background Technology

[0002] Melamine tableware is a synthetic resin tableware made from melamine resin as the main raw material, pressed under high temperature and pressure. In its preparation process, molds are needed for auxiliary processing. However, since melamine tableware is made of plastic, some plastic residue will remain inside the mold during the molding process. For example, patent document CN220197251U discloses a mold cleaning device. This device, with the cooperation of a mold cleaning platform, a drain pipe and a control valve, can manually spray cooling water onto the mold while cleaning the debris on the inner wall of the mold. This not only cools the mold down but also removes the floating dust generated during the mold cleaning process, allowing the cooling water mixed with the floating dust to be discharged to the outside through the drain pipe.

[0003] However, the above-mentioned device cannot effectively clean the adhesive residue inside the mold, thus reducing the cleaning effect. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: A cleaning device for a melamine tableware molding die includes a vacuum cleaner and a vacuum hose. The vacuum hose is connected to the feed end of the vacuum cleaner. The lower end of the vacuum hose is connected to a collection cover. An mounting plate is fixedly installed on the upper end of the inner wall of the collection cover. A rotating shaft is rotatably installed inside the mounting plate. Multiple scrapers are provided at the bottom of the rotating shaft. The outer wall of the collection hood is provided with a driving mechanism, which is used to drive the rotating shaft and scraper to rotate.

[0007] Preferably, the driving mechanism includes a motor and a drive shaft. The drive shaft is located inside the collection shroud. The motor is fixedly mounted on the outer wall of the collection shroud, and the end of the output shaft passes through the collection shroud and is fixedly connected to the drive shaft.

[0008] Preferably, the blades of the plurality of scrapers extend beyond the collection cover and outward.

[0009] Preferably, a flow guide is fixedly installed inside the mounting plate, and the flow guide is rotatably sleeved on the outside of the rotating shaft and the drive shaft, with both ends of the flow guide being tapered.

[0010] Furthermore, the upper and lower sides of the mounting plate are both chamfered.

[0011] Preferably, the suction pipe is a corrugated pipe, and a positioning tube is fixedly sleeved at the lower end of the suction pipe. A handle is fixedly provided on the outer wall of the positioning tube, and the handle is used to control the suction pipe.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model discloses a cleaning device for melamine tableware molding molds.

[0019] This utility model provides, for example Figure 1-3 The cleaning device for a melamine tableware molding mold shown includes a vacuum cleaner 1 and a vacuum pipe 2. The vacuum pipe 2 is connected to the feed end of the vacuum cleaner 1. The lower end of the vacuum pipe 2 is connected to a collection cover 3. The upper end of the inner wall of the collection cover 3 is fixedly provided with a mounting plate 4. The mounting plate 4 is rotatably provided with a rotating shaft 5 inside. The bottom of the rotating shaft 5 is provided with multiple scrapers 6. The blades of the multiple scrapers 6 pass through the collection cover 3 and extend to the outside. The vacuum hose 2 is a corrugated hose. The lower end of the vacuum hose 2 is fixedly fitted with a positioning tube 12. The outer wall of the positioning tube 12 is fixedly fitted with a handle 13, which is used to control the vacuum hose 2. The outer wall of the collection cover 3 is provided with a drive mechanism, which is used to drive the rotating shaft 5 and the scraper 6 to rotate. The drive mechanism includes a motor 7 and a drive shaft 8. The drive shaft 8 is located inside the collection cover 3. The motor 7 is fixedly installed on the outer wall of the collection cover 3, and the end of the output shaft passes through the collection cover 3 and is fixedly connected to the drive shaft 8. The first bevel gear 9 and the second bevel gear 10 are respectively fixedly sleeved at one end of the drive shaft 8 and the rotating shaft 5, and the first bevel gear 9 and the second bevel gear 10 are configured to cooperate.

[0020] In order to seal and protect the mating parts of the rotating shaft and drive shaft, and to prevent impurities from entering the suction pipe and affecting the transmission stability, such as... Figure 2 As shown, the upper and lower sides of the mounting plate 4 are chamfered, and the inside of the mounting plate 4 is fixedly fitted with a flow guide 11. The flow guide 11 is rotatably sleeved on the outside of the rotating shaft 5 and the drive shaft 8. Both ends of the flow guide 11 are set in a pointed cone shape.

[0021] Working principle: First, connect the vacuum cleaner 1 to the power supply, hold the handle 13 on the outer wall of the positioning tube 12, and use the flexible characteristics of the vacuum tube 2 as a corrugated tube to adjust the position of the collection cover 3 so that the blades of the multiple scrapers 6 that protrude from the outside of the collection cover 3 fit into the residual impurity area on the inner wall of the melamine tableware molding mold. The motor 7 on the outer wall of the collection cover 3 is started. The output shaft of the motor 7 drives the drive shaft 8 to rotate inside the collection cover 3. The first bevel gear 9 at the end of the drive shaft 8 rotates synchronously. Since the first bevel gear 9 meshes with the second bevel gear 10 at the end of the rotating shaft 5, the first bevel gear 9 drives the second bevel gear 10 to rotate, thereby causing the rotating shaft 5 to rotate inside the mounting plate 4. When the rotating shaft 5 rotates, the multiple scrapers 6 at its bottom rotate accordingly. The blades of the rotating scrapers 6 scrape off the melamine resin residue impurities adhering to the inner wall of the mold, peeling the stubborn residue off the surface of the mold. At the same time, the vacuum cleaner 1 generates negative pressure, which forms suction inside the collection hood 3 through the suction pipe 2. The impurities scraped off by the scraper 6 enter the collection hood 3 under the action of suction. The chamfered design on the upper and lower sides of the mounting plate 4 can guide the impurities to flow towards the suction pipe 2, avoiding the accumulation of impurities on the surface of the mounting plate 4. In addition, the guide hood 11 (with pointed cones at both ends) inside the mounting plate 4 is sleeved on the outside of the rotating shaft 5 and the drive shaft 8. On the one hand, it can prevent impurities from entering the meshing part of the first bevel gear 9 and the second bevel gear 10, avoiding the impurities from affecting the transmission stability. On the other hand, it can also help guide the impurities to flow towards the suction pipe 2. Finally, the impurities are sucked into the vacuum cleaner 1 and collected through the collection hood 3 and the suction pipe 2. During the cleaning process, the positions of the collection cover 3 and the scraper 6 can be flexibly adjusted by the handle 13 to thoroughly clean the residue in different areas of the mold. After cleaning, turn off the motor 7 and the vacuum cleaner 1, remove the impurity collection component from the vacuum cleaner 1 for cleaning, and the entire mold cleaning operation can be completed.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
