With the development of industry, the spray curing of various mechanical parts has gradually been transformed into a spray curing process in the form of a production line. For example, a constant temperature curing furnace for curing spray powder disclosed on the China Patent Network (publication announcement number CN218013879U) is shown. When such a device is in use, by setting the curing furnace body to a double-layer structure of an inner frame of the curing furnace and an insulating outer frame, and leading the temperature in the inner frame of the curing furnace to the insulating outer frame through the return air duct, the uniform and constant temperature of each part in the inner frame of the curing furnace is ensured through the cooperation of the electric heating wire.

[0003] However, the curing ovens used in the aforementioned patents and in the current market still have some shortcomings. The existing method uses hot air flow to evenly distribute heat throughout the curing oven for heating and curing. However, this hot air easily loses energy during circulation, often failing to evenly distribute heat to all locations, resulting in insufficient heating and curing stability. Therefore, those skilled in the art have provided a curing oven for a spray coating production line to address the issues raised in the aforementioned background technology. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] See also Figure 1-4The utility model provides a technical solution for a curing furnace for a spraying production line: a curing furnace for a spraying production line, comprising a support frame 1, a chain plate conveyor 2 is arranged on the top of the support frame 1, and the transmission chain plates of the chain plate conveyor 2 are arranged with multiple sets of tooling mechanisms, the tooling mechanisms include multiple sets of transmission chain plates 21 arranged along the transmission direction of the chain plate conveyor 2, the upper end of the plate frame of the transmission chain plates 21 is symmetrically provided with two sets of support seats 10, and the top of the support of each set of support seats 10 is installed with a material placement tool 4, the furnace body of the baking furnace 3 is arranged with multiple sets of support booms 8, and the bottom end of the arm of the support boom 8 is provided with a transmission rack 9 for driving the material placement tool 4 to rotate, and the middle part of the swivel seat of the support seat 10 is provided with There is a differential gear A11, and the differential gear A11 and the transmission rack 9 are meshed and connected through the differential gear B12. When the curing furnace is used to perform a curing process on the sprayed mechanical parts, the mechanical parts to be cured are placed in the loading fixture 4 in sequence, and then the loading fixture 4 loaded with mechanical parts is transported to the baking oven 3 in sequence under the transmission drive of the chain plate conveyor 2. When the loading fixture 4 is transported to the inside of the baking oven 3, based on the meshing transmission of the differential gear A11, the differential gear B12 and the transmission rack 9, the horizontal thrust is converted into a rotational thrust, which pushes the loading fixture 4 on the support seat 10 to rotate, so that the mechanical parts maintain the state of self-rotation and transportation, and perform all-round heating and curing work.

[0026] A baking oven 3 covering the chain plate conveyor 2 is provided at the upper end of the support frame 1, and an electric heating plate 7 opposite to the material placing tool 4 is symmetrically provided inside the furnace body of the baking oven 3. The electric heating plate 7 is a heating wire structure. By controlling the electric heating plate 7 as a heat source, a heating and curing chamber is formed in the baking oven 3 to heat and cure the mechanical parts conveyed in a circulation manner.

[0027] Electric-controlled opening and closing doors 5 are symmetrically installed on both sides of the furnace body of the baking oven 3. The electric-controlled opening and closing doors 5 include side support seats 51. An electric telescopic rod 52 is provided in the middle of the support of the side support seat 51, and an opening and closing door 54 is provided at the telescopic end of the electric telescopic rod 52. The support of the side support seat 51 is symmetrically connected on both sides with a lifting guide rod 53 fixedly connected to the opening and closing door 54. The opening and closing of the opening and closing door 54 is driven by controlling the electric telescopic rod 52. When the material loading tooling 4 is circulated and transported, the opening and closing door 54 is cyclically opened and closed, and the material loading tooling 4 enters and exits the baking oven 3. Then, by closing the opening and closing door 54, the heat loss in the baking oven 3 is reduced.

[0028] A flue gas purifier 6 is installed above the furnace body of the baking furnace 3. The flue gas purifier 6 includes a purification cylinder 61.

A purification filter element 62 is installed inside the core tube of the purification cylinder 61. The purification filter element 62 is a multi-layer filter element structure, and the multi-layer filter element is a stainless steel filter mesh and an activated carbon filter mesh from the outside to the inside. By controlling the operation of the blower 63, under the conductive combination of the purification cylinder 61 and the flue gas pipeline 64, the flue gas generated by the curing in the baking furnace 3 is adsorbed, and the flue gas is discharged after being filtered and purified by the purification filter element 62, thereby reducing the overflow of flue gas and the pollution of the on-site working environment.

[0029] The working principle of the present invention is as follows: when a curing process is performed on mechanical parts after spraying using a curing oven, the mechanical parts to be cured are sequentially placed in the loading fixture 4, and then the loading fixture 4 loaded with the mechanical parts is sequentially transported into the baking oven 3 under the transmission drive of the chain plate conveyor 2. When being transported into the baking oven 3, the opening and closing door 54 of the electric-controlled opening and closing door 5 is controlled to open and close, serving as the entrance of the loading fixture 4. When the loading fixture 4 is transported into the baking oven 3, the meshing transmission of the differential gear A11, the differential gear B12 and the transmission rack 9 converts the horizontal thrust into the rotational thrust, pushing the loading fixture 4 on the support seat 10 to rotate, so that the mechanical parts maintain the state of self-rotation and transportation, and are subjected to all-round heating and curing work by the electric heating plate 7.

[0030] After the mechanical parts are cured and transported to the other end, the cured mechanical parts are circulated out by opening the opening and closing door 54 of the electric-controlled opening and closing door 5 at the other end. At this time, the mechanical parts can be taken out. Then, in this way, the mechanical parts are subjected to a continuous and uninterrupted curing process in the form of a production line, which improves the curing efficiency while ensuring the comprehensiveness of the curing.

[0031] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
