Description
Technical Field
[0001] This utility model relates to the field of heating device technology, and in particular to an easy-open lid engraving heating device. Background Technology
[0002] Easy-open lids are key components on food and beverage packaging containers. The engravings on the opening part need to be treated by a specific heating process before sealing to ensure airtightness while achieving easy-open performance. This heating process has high requirements for temperature uniformity, control precision, and processing efficiency.
[0003] Current technology typically employs heating equipment for easy-open lid scribing, consisting of a frame, a conveying system, a heating module, and a cooling system. The heating module often uses induction heating or resistance heating, generating an alternating magnetic field or Joule heating through electrical energy to locally and instantaneously heat specific areas of the easy-open lid as it moves to the heating station, altering its material microstructure to achieve the preset scribing characteristics. The conveying system is responsible for sequentially transporting the workpiece through each station, while the cooling system is used to cool and shape the stamped or heated workpiece.
[0004] In existing technological practices, easy-opening workpieces are often fixed in the heating station using simple mechanical limiting or pneumatic clamping. This makes it difficult to ensure that each workpiece can be accurately and consistently positioned during high-speed transport, leading to displacement of the heating area. This directly affects the uniformity of the engraving and the yield rate. In addition, oxide scale generated during the heating process, as well as coolant splashed in the subsequent cooling stage, accumulate in the equipment working area and on the workpiece surface. This not only pollutes the processing environment, but if impurities in the coolant are not effectively separated and filtered and are directly recycled, they will clog the spray pipes and affect the cooling effect, and may even damage the workpiece surface. Therefore, an easy-opening engraving heating device is proposed to solve the above problems. Utility Model Content

The waste liquid generated, mixed with impurities, flows into the filter chamber at its bottom. The baffle inside guides the water flow through the filter screen, and the impurities are intercepted. To prevent the filter screen from clogging, motor two of the filter assembly starts at regular intervals. Through the planar linkage mechanism composed of connecting column one, connecting plate one, connecting column two, connecting plate two, support column, rotating column and slider two, the scraper is driven to perform reciprocating scraping motion on the top of the filter screen, automatically removing the filter residue accumulated on the screen. This process realizes automatic cleaning of the processing environment and efficient filtration and recovery of coolant, significantly improving the recycling rate of coolant, ensuring the continuous and stable operation of the equipment and the cleanliness of the production environment.

[0043] Working principle: During operation, the easy-open cover workpiece is conveyed by the conveyor belt 5 to the heating station below the fastening mechanism 2. The hydraulic cylinder 23 is activated, pushing the rotating rod 24 at its drive end to move downward along the inner wall of the cross plate 211. The rotating rod 24 drives the top plate 25 to press down synchronously. Multiple cylinders 26 fixedly connected to the plate 25 descend accordingly. The cylinders 26 push the arc plate 27 on one side to move. The arc plate 27 is connected to the bottom slider 29 through the cylinder 28. The slider 29 descends smoothly under the constraint of the guide rail 210, ensuring that the arc surface on the inner side of the multiple arc plates 27 is completely in contact with the outer edge of the workpiece, thereby accurately clamping and positioning the workpiece. Subsequently, the heating column 212 fixed to the top of the guide rail 210 is energized, and the movable coil 213 inside generates a high-frequency induced magnetic field or resistance heat to quickly and evenly heat the specific engraved area of the workpiece. After the heating process is completed, the hydraulic cylinder 23 rises, driving the entire clamping unit to release the workpiece, and the conveyor belt 5 then sends it away from the heating station.
[0044] When the workpiece enters the area of the cleaning mechanism 3, motor 1 32 starts, driving the brush 33 at its front end to rotate at high speed, thoroughly cleaning the workpiece surface and processing area of any oxide scale and other impurities that may be attached. Simultaneously, the water spray pipe 34 installed inside the support plate 2 31 connects to cleaning fluid or coolant through a pipe 35 on one side, spraying it onto the cleaning plate 36 area to fully cool and clean the workpiece. The resulting waste liquid, mixed with impurities, flows into the filter chamber 37 at the bottom of the support plate 2 31. A baffle 38 inside the filter chamber 37 guides the water flow, and impurities are effectively intercepted by the filter screen 39 to prevent excessive... When filter screen 39 becomes clogged, motor 41 of filter assembly 4 starts periodically. Motor 41 drives connecting column 42 to rotate, which in turn drives scraper 49 to reciprocate and scrape the top of filter screen 39 through a planar linkage mechanism consisting of connecting plate 43, connecting column 44, connecting plate 45, support column 46, rotating column 47, and slider 48. This automatically removes the accumulated filter residue on the screen, keeping filter screen 39 clear. The filtered clean liquid is collected and recycled to water spray pipe 34 for reuse, thus effectively maintaining the cleanliness of the working area and achieving efficient recycling of coolant resources.
[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
