Description

Technical Field

[0001] This application relates to the field of heat curing technology for sprayed products, and in particular to a temperature regulation structure and curing oven based on the product's operating path. Background Technology

[0002] In the spraying process, when a product, such as a small product—like a thermos cup blank—needs to be heated and cured after the spraying operation, a curing oven, also known in the industry as a drying oven, is required.

[0003] Currently, common curing ovens typically use a method of supplying air or heating the entire surface when heating and curing products inside. However, this method cannot adjust the heating and curing temperature at different locations along the product's path, making it difficult to achieve uniform heating and curing of the coating, and ultimately hindering the improvement of product quality. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a temperature regulation structure and curing oven based on the product's running path. By setting several air outlets along the product's running path and an air outlet adjustment plate that can adjust the size of the air outlets, the heating and curing temperature of the product at different positions along the running path can be adjusted, resulting in a very uniform heating and curing effect and a real and effective improvement in product quality.

[0005] As a first aspect of this disclosure, a temperature regulation structure based on a product operating path is provided, comprising: an air supply jacket and a plurality of adjustable air supply structures, wherein the air supply jacket is disposed above the product and extends to cover the product operating path, the adjustable air supply structures are disposed in the air supply jacket, the adjustable air supply structures are arranged sequentially along the product operating path, the adjustable air supply structure includes an air outlet and an air outlet adjustment plate, the air outlet is opened in the air supply jacket, and the air outlet adjustment plate is slidably connected to the air supply jacket and changes the size of the air outlet by sliding.

[0006] In one feasible implementation, the product operating path is a one-way operating path, and the adjustable air supply structure is uniformly arranged along the one-way operating path.

[0007] In one feasible implementation, the product operating path includes a reversible operating path, and the adjustable air supply structure is evenly arranged along the reversible operating path and the non-reversible operating path, respectively, and the distance between the outermost operating path and the adjacent middle operating path is greater than the distance between two adjacent middle operating paths.

[0008] In one feasible implementation, the reversing running path and the non-reversing running path are arranged in parallel intervals along the length of the furnace body, and the reversing running path and the non-reversing running path are connected to form a continuous running path, with the reversing running path and the non-reversing running path forming an arc-shaped connection at the end.

[0009] In one feasible implementation, the single adjustable air supply structure has multiple air outlets, and these multiple air outlets are arranged evenly along the product running path. The air outlet adjustment plate in the single adjustable air supply structure can simultaneously cover the multiple air outlets.

[0010] In one feasible implementation, the air outlet adjusting plate has a sliding hole, and a guide mounting post is installed on the air supply interlayer. The air outlet adjusting plate is fitted onto the guide mounting post through the sliding hole to achieve a sliding connection between the air outlet adjusting plate and the air supply interlayer.

[0011] In one feasible implementation, the air outlet adjusting plate further includes a sliding operation part, which protrudes outward relative to the air outlet adjusting plate.

During the sliding process of the return air vent adjustment plate, the through holes can achieve two return air vent modes: one is to keep one row of return air vents in a fully open state while the other row of return air vents can be adjusted in size; the other is to adjust both rows of return air vents from a fully open state to a fully closed state.

[0015] As a second aspect of this disclosure, a curing oven is provided, the curing oven including an oven body, the oven body being provided with the temperature regulation structure set according to the product running path as described above, the curing oven also including a conveyor chain and a plurality of product fixing fixtures mounted on the conveyor chain, the products being mounted on the product fixing fixtures to be heated and cured in the oven body along the running path of the conveyor chain.

[0028] To better understand the technical solutions provided in the embodiments of this specification, the technical solutions of the embodiments of this specification will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this specification and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this specification, rather than limitations on the technical solutions of this specification. In the absence of conflict, the embodiments of this specification and the technical features in the embodiments can be combined with each other.

[0029] The following is in conjunction with the appendix Figure 1-10 This application describes a temperature regulation structure and curing oven based on a product operation path setting.

[0030] A temperature regulation structure based on the product's running path according to an embodiment of this utility model includes: an air supply jacket 10 and several adjustable air supply structures 20. The air supply jacket 10 is located above the product 30 and extends to cover the product's running path. The adjustable air supply structures 20 are located in the air supply jacket 10 and are arranged sequentially along the product's running path. Each adjustable air supply structure 20 includes an air outlet 21 and an air outlet adjustment plate 22. The air outlet 21 is opened in the air supply jacket 10, and the air outlet adjustment plate 22 is slidably connected to the air supply jacket 10 and changes the size of the air outlet 21 by sliding.

[0031] By configuring the air supply jacket 10 and the adjustable air supply structure 20, the hot air volume is adjusted at different locations along the product's operating path. Adjusting the hot air volume changes the heating temperature at those locations, thus allowing for temperature regulation of the product 30 at different points along its operating path. This promotes uniform heating and curing of the product coating, thereby improving product quality. If different heating and curing temperatures are required in the early, middle, and late stages of curing, the temperature can be adjusted at different locations along the product's operating path using the corresponding adjustable air supply structures 20, achieving the desired temperature.

[0032] It should be noted that in some implementations, the air supply jacket 10 is designed to match the conventional rectangular structure of the curing oven 40, forming a rectangular plate structure, and the adjustable air supply structure 20 is sequentially arranged on the air supply jacket 10 along the product running path.

[0033] In some implementations, the product operating path is a single-pass path, and the adjustable air supply structure 20 is uniformly arranged along this single-pass path. Here, a single-pass path can be understood as the product 30 entering from one end of the curing oven 40 and exiting directly from the opposite end, without any intermediate backtracking. For example, it could enter from one end of the curing oven 40 along its length and exit from the other end. In this implementation, the adjustable air supply structure 20 is sequentially arranged at different positions along this single-pass path, thereby achieving temperature regulation at different locations.

[0034] In some implementations, the product running path may include a reversible running path. The adjustable air supply structure 20 is evenly distributed along both the reversible and non-reversible running paths, with the distance between the outermost running path and the adjacent middle running path being greater than the distance between two adjacent middle running paths. This arrangement allows for multiple product running paths within the curing oven 40, enabling repeated and continuous curing of the product 30. This is particularly advantageous for the miniaturization of the curing oven 40 and is also more environmentally friendly and energy-efficient. Compared to a single-pass running path, for products with consistent heating and curing requirements, the length of the curing oven in this implementation can be significantly reduced, decreasing the floor space and truly achieving a miniaturized design for the curing oven 40. Furthermore, the spacing between adjacent running paths adopts the above-mentioned setting style. This is mainly because when product 30 enters the curing oven 40 and is located in the middle of the four running paths, the required hot air volume is large and the temperature requirement is higher. At this time, the four running paths in the middle are closer together, and the adjustable air supply structure 20 is set more densely, which is conducive to increasing the air volume to obtain a higher heating and curing temperature.

[0035] refer to Figure 2 , Figure 3 In this specific implementation, the curing oven 40 is equipped with 6 operating paths, including 3 non-returning operating paths and 3 returning operating paths. Thus, the curing oven 40 simultaneously has 6 operating paths, allowing the coating of product 30 to be continuously and sequentially heated and cured along these 6 operating paths. The returning and non-returning operating paths are arranged parallel and spaced along the length of the curing oven 40, and are connected to form a continuous operating path. The returning and non-returning operating paths connect at their ends in an arc shape. This design ensures that the operating paths are arranged in an orderly back-and-forth manner along the width of the curing oven 40, allowing for a reasonable width of the curing oven 40 without being excessively wide and hindering its miniaturization design.

[0036] In this embodiment of the invention, the single adjustable air supply structure 20 has multiple air outlets 21, which are evenly arranged sequentially along the product running path. The air outlet adjustment plate 22 in the single adjustable air supply structure 20 simultaneously covers all the multiple air outlets 21. In this configuration of the adjustable air supply structure 20, the air outlets 21 are also arranged along the product running path, allowing air to be supplied directly to the product 30 below, providing positive heating with minimal heat loss. Furthermore, the air outlet adjustment plate 22 has sufficient coverage area to accommodate gradual adjustment of the air outlet 21 size from large to small.

[0037] In this embodiment of the invention, the air outlet adjusting plate 22 has a sliding hole 23, and a guide mounting post 24 is installed on the air supply interlayer 10. The air outlet adjusting plate 22 is fitted onto the guide mounting post 24 through the sliding hole 23 to achieve a sliding connection between the air outlet adjusting plate 22 and the air supply interlayer 10. Simultaneously, the air outlet adjusting plate 22 also has a sliding operation part 25, which protrudes outward relative to the air outlet adjusting plate 22 to facilitate operation during sliding.

[0038] In this embodiment of the invention, a return air interlayer 50 is further included. The return air interlayer 50 is disposed below the conveyor chain 60 that conveys the product 30 and extends to cover the product running path. A plurality of adjustable return air structures 70 are sequentially arranged on the return air interlayer 50 along the product running path. Specifically, the adjustable return air structure 70 includes a return air inlet 71 and a return air inlet adjusting plate 72. The return air inlet 71 is opened in the return air interlayer 50, and the return air inlet adjusting plate 72 is slidably connected to the return air interlayer 50 and changes the size of the return air inlet 71 by sliding.

[0039] With the above settings, the product 30 is also equipped with the adjustable return air structure 70 below the conveyor chain 60, and it is also set along the product running path. In this way, with the dual settings of the upper adjustable air supply structure 20 and the lower adjustable return air structure 70, the temperature of the product 23 at different positions on the running path can be adjusted more accurately, so that the heating and curing temperature of the product 30 from top to bottom can be effectively controlled, and at the same time, hot air can be discharged from the return air jacket 50 with precise air volume.

[0040] In some implementations, the return air inlets 71 in the single-adjustable return air structure 70 are arranged in two rows, with two return air inlets 71 arranged along the product running path in each row. The return air inlet adjusting plate 72 is provided with through holes 73 arranged in a single row, each containing two holes arranged along the product running path. The through holes 73 can achieve two return air inlet modes during the sliding process of the return air inlet adjusting plate 72: one is to keep one row of return air inlets 71 in a fully open state, while the size of the other row of return air inlets 71 can be adjusted; the other is to adjust both rows of return air inlets 71 from a fully open state to a fully closed state.

[0041] With the above settings, compared to the adjustable air supply structure 20 above product 30, the number of return air vents 71 is increased, and the adjustable return air structure 70 below has a larger return air volume when returning air. This is mainly because the heating and curing temperature below is not as high as above, so the gas after heating and curing needs to be quickly discharged in the return air state.

[0042] A curing oven 40 according to an embodiment of the present invention includes the temperature regulation structure set according to the product running path as described above. Hot air is supplied from the air supply jacket 10 through the air outlet 21 to heat and dry the product 30 below. After being heated and dried, the hot air is discharged from the return air jacket 50 below and returns to the heating box 80 at the top of the curing oven 40. After heating, the hot air continues to heat and dry the product 30 below through the air supply jacket 10 under the action of the circulating fan 90. This cycle forms a continuous heating and drying process, which meets the requirements of energy saving and environmental protection.
