Description

Technical Field

[0001] This utility model relates to the field of putty technology, and in particular to a baking device for putty. Background Technology

[0002] The main purpose of putty is to fill and repair defects such as pits, pinholes, cracks and small welds on the substrate, so as to achieve a smooth and even surface on the substrate before topcoat. It is widely used in train manufacturing, ship manufacturing, bus manufacturing, engineering machinery manufacturing, machine tool and mechanical equipment manufacturing, automobile repair, furniture, molds, concrete buildings and various metal products, wood products and fiberglass products that require filling and repair.

[0003] Chinese patent CN218722953U discloses a baking device for putty, including a machine base. A support rod is fixedly connected to the bottom of the top of the machine base. A motor is fixedly connected to the top of the support rod on its left side away from the machine base. A control panel is fixedly connected to the right side of the support rod near the top. A gear is fixedly connected to the right side of the motor. A transmission rod meshes with the gear, and a rotating hole is formed inside the gear. By adding a support rod to the top of the machine base and installing a conveyor belt in the middle of the support rod, a conveyor belt conveying effect is achieved, ensuring uniform speed and even baking of the putty. This solves the problem of uneven baking and incomplete hardening of putty caused by traditional handheld baking devices, reducing the possibility of incomplete hardening caused by handheld devices. However, due to the fixed position of the heating rod and the inconsistent distance from the product, this patent will have the problem of uneven heating. In addition, the heating chamber is open at both the front and the back, which causes the hot air inside the heating chamber to convect with the cold air outside. A large amount of heat is lost from the openings, which not only makes it difficult to maintain the internal temperature, but also causes the heating rod to run at a high load continuously, resulting in a significant increase in energy consumption.

Finally, the air is heated by the hot air blower 16 to form hot air. The hot air is sent into the air supply duct 22 through the hot air duct 16, the hot air tee connector 18 and the air supply duct 19 in sequence, and blown towards the items to be baked through the air outlet 23.

[0029] Working Principle: Items coated with putty are placed on a conveyor belt. As the items approach the entrance of the baking hood, the roller shutter motor at the entrance operates, causing the roller shutter rollers to retract and open the baking hood entrance. The items enter the baking hood under the influence of the conveyor belt. The roller shutter mechanism at the entrance rotates, releasing the roller shutter. Under the action of a counterweight, the roller shutter moves downwards along a vertical groove until it almost contacts the conveyor belt, thus covering the entrance. The roller shutter mechanism at the exit closes the exit. A hot air blower starts, sending hot air into the air duct and blowing it out from multiple air nozzles 23 to bake the items. After baking, the roller shutter mechanism at the exit operates, retracting the roller shutter onto the roller shutter rollers and opening the exit. The baked items leave the baking hood under the influence of the conveyor belt. Subsequently, the roller shutter mechanism at the exit operates, lowering and closing the roller shutter, awaiting the next batch of items to enter. This completes one baking process.
