Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of electromagnetic dryers, and in particular to an electromagnetic dryer for food cans. Background Technology
[0002] Based on the manufacturing process, metal cans are classified into two-piece and three-piece cans. Three-piece cans have a vertical weld seam along a straight line on the cylindrical wall. After the weld seam process, a protective layer needs to be applied to the weld area to provide acid and sulfur resistance without contaminating the contents. The applied area must be immediately heated and dried after application. Existing technology publication CN216898122U discloses an electromagnetic drying device for metal tubes, including a base, a drying chamber fixedly connected to one side of the base, a heating chamber fixedly connected to one side of the drying chamber, an electromagnetic heating plate fixedly connected to one side of the heating chamber, a flow guide hood fixedly connected to one side of the heating chamber, and a suction fan fixedly connected to the end of the flow guide hood away from the heating chamber via a pipe. A T-junction is fixedly connected to the outlet of the suction fan via a pipe. However, this method is inconvenient for adjusting the distance between the electromagnetic induction burner and the metal can, making it difficult to maintain the correct distance when dealing with different types of metal cans, thus compromising the drying effect. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides a food can electromagnetic dryer that can adjust the distance between the electromagnetic induction burner head and the metal can, ensuring the drying effect, making the adjustment movement more stable, and avoiding the shaking of the electromagnetic induction burner head during the movement.

The top of the dryer outer casing has left and right mounting holes for easy installation. A conveyor is installed in the middle of the bottom of the dryer outer casing. The electromagnetic induction burner head is installed inside the dryer outer casing via the adjusting component. A guiding component is installed between the electromagnetic induction burner head and the dryer outer casing. The heat dissipation component is installed inside the dryer outer casing. The conveyor transports the metal cans, and the adjusting component allows for adjustment of the distance between the electromagnetic induction burner head and the metal can to ensure drying effect. Simultaneously, the guiding component ensures smoother adjustment movement, preventing the electromagnetic induction burner head from shaking during operation. The heat dissipation component dissipates heat from the upper part of the dryer outer casing, controlling the temperature and preventing damage to the equipment.
[0005] Preferably, the adjusting components include a partition, a reducer, an adjusting motor, a threaded rod, a threaded sleeve, and an electromagnetic coil controller. The partition is installed inside the dryer's outer casing, the reducer is installed on the top of the dryer's outer casing, the input end of the reducer is connected to the output end of the adjusting motor, the output end of the reducer passes through the top of the dryer's outer casing and is fitted with a threaded rod, the threaded sleeve is screwed onto the outer wall of the threaded rod, and the bottom of the threaded sleeve passes through the partition and is fitted with an electromagnetic coil controller, which is connected to the electromagnetic induction furnace head. When the metal can moves below the electromagnetic coil controller, it is dried. Starting the adjusting motor drives the threaded rod to rotate through the reducer, pushing the threaded sleeve to slide on the partition, thereby adjusting the distance between the electromagnetic induction furnace head and the metal can, ensuring the drying effect.
[0006] Preferably, it also includes multiple limiting strips and limiting retaining rings. Multiple limiting strips are axially installed on the outer wall of the threaded sleeve. The limiting strips are slidably installed on the partition plate, and the limiting strips are installed at the top of the limiting strips. When the threaded sleeve moves on the partition plate, it drives the limiting strips to slide on the partition plate, thereby guiding and limiting the threaded sleeve.
[0007] Preferably, the guiding component includes two guide columns, multiple vertical rods, and multiple guide plates. Guide columns are symmetrically installed at the left and right ends of the top of the electromagnetic coil controller. The guide columns are slidably installed on the partition plate. A guide groove is opened on the inner wall of the rear side of the dryer outer casing. The vertical rods are installed in the guide groove. The guide plates are slidably installed inside the guide groove and on the outer wall of the vertical rod. The front end of the guide plate is connected to the electromagnetic coil controller. When the electromagnetic coil controller moves, it drives the guide columns to slide on the partition plate, and at the same time drives the guide plates to slide on the outer wall of the vertical rod and in the guide groove, so that the electromagnetic coil controller can adjust and move more smoothly, avoiding shaking of the electromagnetic induction furnace head during movement.
[0008] Preferably, the heat dissipation component includes two cooling water pipes and two connectors. The two cooling water pipes are connected and located above the partition inside the dryer's outer casing. The ends of the cooling water pipes pass through the outer wall of the dryer's outer casing and are fitted with connectors. During operation, the cooling water pipes are connected to the heat dissipation device through the connectors, allowing cooling water to flow inside the cooling water pipes, dissipating heat from inside the dryer's outer casing, controlling the temperature, and preventing damage to the equipment.
[0009] Preferably, it also includes two inspection doors and two sets of hinge chains. Two inspection ports are opened at the front end of the dryer outer casing, and the tops of the two inspection doors are hinged to the inspection ports by the hinge chains. Pulling the inspection doors can open the inspection ports, which facilitates internal inspection and maintenance.
[0010] Preferably, a conveying block is provided on the outer surface of the conveyor; when the conveyor conveys the iron can, the iron can is limited by the conveying block to prevent it from falling during the movement.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the metal can is conveyed by the conveyor, the distance between the electromagnetic induction furnace head and the metal can is adjusted by the adjustment component to ensure the drying effect, and the guide component makes the adjustment movement more stable, avoiding the electromagnetic induction furnace head from shaking during the movement. The heat dissipation component can dissipate heat to the upper side of the inner side of the dryer casing, control the temperature, and avoid damage to the equipment. Attached Figure Description
