Description

Technical Field

[0001] This utility model relates to the technical field of automotive interior product processing equipment, and more specifically, to an energy-saving press oven. Background Technology

[0002] In the processing of automotive interiors, interior products are usually molded to ensure that the final product can accurately fit the mold shape. Before molding, the base material of the interior product needs to be heated to soften the material and reduce its rigidity, so that it can be smoothly deformed under the pressure of the mold and avoid the mold pressing being blocked or the base material cracking due to the base material being too hard.

[0003] Existing pre-molding heating equipment mainly falls into three categories: resistance heating, infrared heating, and hot air circulation heating. Infrared heating, due to its rapid heating characteristic, is widely used in heating substrates for automotive interior products. However, after long-term use, the infrared heating tubes in infrared heating equipment typically undergo gradual oxidation or evaporation due to the high-temperature environment, leading to a decrease in their radiation efficiency and a significant increase in energy consumption. Furthermore, the lifespan of infrared heating tubes is relatively short, requiring regular replacement, which is detrimental to the industry's development needs for green production and energy conservation.

[0004] The above shortcomings need to be improved. Utility Model Content

[0005] In order to overcome the problem that the energy consumption of existing heating equipment increases significantly with the time of use, this utility model provides an energy-saving press oven.

[0014] According to the above-described scheme of this utility model, the feed support is provided with a driven rotating shaft.

[0020] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] It should be noted that when a component is referred to as "fixed," "set," or "connected" to another component, it may be located directly or indirectly on that other component. The terms "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or position based on the accompanying drawings, and are for ease of description only, and should not be construed as limiting the technical solution. The terms "first," "second," etc., are used for ease of description only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. "Many" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.

[0022] See Figures 1 to 5 As shown, this utility model provides an energy-saving press oven, comprising: an oven body 10, the oven body 10 including a heating chamber 11 and an oven support 12, the heating chamber 11 having a heating chamber, the upper end of the heating chamber having a ceramic heating platform 13, and the lower end of the heating chamber having an aluminum plate heating platform 14; a feeding bracket 20, the feeding bracket 20 being installed at one end of the feeding port of the oven body 10; a discharging bracket 30, the discharging bracket 30 being installed at one end of the discharging port of the oven body 10, and the discharging bracket 30 having a motor 31; and a conveyor belt 40, the two ends of the conveyor belt 40 being respectively installed on the feeding bracket 20 and the discharging bracket 30, the upper belt 41 of the conveyor belt 40 passing through the heating chamber and being driven by the motor 31.

[0023] In fact, both the ceramic heating plate 132 and the aluminum plate 141 are planar heating elements. Compared with traditional infrared heating tubes, the ceramic heating plate 132 has a larger heating area and more uniform heat distribution, forming a uniform thermal environment across the entire surface. In contrast, infrared heating tubes are linear or tubular heating elements, and heat diffuses through radiation, which can easily lead to localized hot spots, resulting in uneven heating of different parts of the workpiece and affecting processing consistency. Furthermore, the aluminum plate 141 can conduct heat through direct contact with the upper belt 41, greatly improving conversion efficiency and reducing ineffective heat loss into the air.

[0024] Furthermore, the ceramic heating platform 13 is uniformly equipped with ceramic fixing strips 131, and ceramic heating plates 132 are uniformly arranged on the ceramic fixing strips 131. The ceramic heating plates 132 are evenly distributed through the ceramic fixing strips 131, forming a grid-like layout, which can eliminate heating blind spots, avoid local overheating, and improve the heating uniformity of the product. Moreover, the ceramic material is resistant to high temperature and corrosion, which can reduce the deformation of the heating plates caused by thermal expansion or corrosion from acidic gases emitted by the interior substrate during heating, thus extending the service life. The ceramic heating platform is also provided with mounting parts 133, and the heating box is also provided with fixing parts 16. The ceramic heating platform is positioned on the fixing parts 16 through the mounting parts 133, and the height of the ceramic heating platform can be adjusted by the bolts connecting the mounting parts 133 and the fixing parts 16.

[0025] Furthermore, the aluminum plate heating platform 14 is uniformly covered with aluminum plates 141. Due to the high thermal conductivity of the aluminum plates 141, heat can be quickly transferred to the bottom of the product on the conveyor belt 40, shortening the preheating time. In addition, the aluminum plates 141 can also support the product substrate and play a load-bearing role.

[0026] Specifically, in this utility model, a heat insulation platform 15 is provided at the bottom of the heating box 11, and heat insulation cotton 151 is evenly laid on the heat insulation platform 15 to effectively block the transfer of heat to the external environment and reduce the energy consumption of the heating equipment during operation.

[0027] In this invention, a limiting shaft 17 is provided below the heating chamber 11. The limiting shaft 17 is mounted on the oven support 12 via a vertical bearing 171. The lower belt 42 of the conveyor belt 40 is positioned below the limiting shaft 17. The limiting shaft 17 allows for precise positioning of the lower belt 42 of the conveyor belt 40, preventing the lower belt 42 from sagging or deviating due to its own weight. This ensures synchronous transmission of the upper and lower belts 42 of the conveyor belt 40, without affecting the workpiece conveying speed. Furthermore, the vertical bearing 171 has a strong load-bearing capacity and low rotational resistance, reducing friction between the limiting shaft 17 and the support, lowering the power load on the motor 31, and improving the stability of the conveyor belt 40 during operation.

[0028] Furthermore, the upper belt 41 of the conveyor belt 40 passes through the heating chamber and is positioned above the aluminum plate heating platform 14. This belt directly adheres to the aluminum plate heating platform 14, allowing the workpiece to be in close contact with the heat source during transport. This reduces the air insulation layer between the workpiece and the platform, improving heat transfer efficiency and shortening heating time. In practice, the heating temperature range of the press oven is typically below 300℃, and in actual use does not exceed 280℃. The conveyor belt 40 is made of Teflon mesh belt, which possesses excellent properties such as high temperature resistance, corrosion resistance, non-adhesion, fire retardancy, and breathability, effectively coping with high temperatures and corrosive gases emitted from automotive interior product substrates.

[0029] Furthermore, the discharge bracket 30 has a drive gear 32 on its motor 31, a transmission shaft 33 on its drive shaft 33, and a transmission gear 34 on its transmission shaft 33. The drive gear 32 and the transmission gear 34 are connected by a chain 35. A bearing 36 is mounted on the transmission shaft 33, and a bearing housing 37 is fitted around the bearing 36. The bearing housing 37 is mounted on the discharge bracket 30. The feed bracket 20 has a driven shaft 21.

[0030] In fact, in this utility model, the conveyor belt 40 is annularly sleeved on the outside of the driven shaft 21 of the feeding bracket 20 and the transmission shaft 33 of the discharging bracket 30, and multiple rollers 43 are installed on the feeding bracket, the oven bracket and the discharging bracket to support the conveyor belt.

[0031] Specifically, the oven body 10 is provided with a cabinet door 18 at the upper end. The cabinet door 18 is installed above the heating chamber 11 by a top pressing block 19. The cabinet door 18 is also provided with a handle 181 to facilitate the maintenance and replacement of the heating platform.

[0032] In fact, in this utility model, the press oven is also equipped with an emergency button 38. When the press oven malfunctions, the emergency button 38 can be pressed to pop out the locking block, thereby restricting the operation of the transmission shaft 33.

[0033] Furthermore, the press oven of this utility model is also equipped with an electrical box 50, which is used to control the power supply of the entire oven and to allocate independent power supplies to the ceramic heating platform 13, the aluminum plate heating platform 14, the motor 31, etc., so as to avoid a single circuit failure affecting the overall equipment.

[0034] In this embodiment, the operation steps of the press oven equipment are as follows: First, the product substrate to be baked is placed on the conveyor belt 40 of the feeding bracket 20. The operation of the motor 31 is controlled by the electrical box 50. The drive gear 32 on the motor 31 drives the chain 35 to rotate, so that the transmission gear 34 drives the transmission shaft 33 to rotate. When the transmission shaft 33 rotates, the bearing 36 reduces the frictional resistance with the discharge bracket 30, so as to quickly transfer the product substrate on the conveyor belt 40 of the feeding bracket 20 to the heating box 11 through the feeding port. Then, the baking time of the product substrate is set by the electrical box 50. The product substrate is baked by the ceramic heating platform 13 and the aluminum plate heating platform 14. The heat loss is reduced by the heat insulation cotton 151 under the heating box 11 to improve the energy utilization rate. Finally, the baked product substrate is transported to the conveyor belt 40 of the discharge bracket 30 through the discharge port. The product substrate is then molded by the subsequent molding equipment.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
