Description

Technical Field

[0001] This utility model relates to the field of adhesive spraying drying ovens, and in particular to a drying oven used in an automotive product adhesive spraying production line. Background Technology

[0002] In automobile manufacturing, adhesive spraying is widely used in the bonding, sealing, and vibration damping of parts. After the adhesive is sprayed, it needs to be cured in a drying oven to ensure bonding strength and product quality.

[0003] Traditional drying ovens typically use hot air circulation heating, with workpieces transported into the oven via a conveyor belt for drying. However, the conveyor belts are mostly flat, and the workpieces are placed directly on the conveyor belt, resulting in uneven heating of the part of the workpiece in contact with the conveyor belt. The hot airflow cannot fully surround the workpiece, especially for large or complex automotive parts, resulting in poor drying effect and affecting the quality of adhesive curing. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a drying oven for an automotive product adhesive spraying production line, which solves the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a drying oven for an automotive product adhesive spraying production line, comprising an oven body and a plate chain conveyor belt passing through the oven body, an air supply and heating component provided in the upper part of the oven body cavity, the plate chain conveyor belt comprising several plates, each plate having a movable top block, the plate chain conveyor belt having upper and lower layers, with a receiving plate provided between the upper and lower layers, and a guide groove provided on the receiving plate to cooperate with the top block; when the plate chain conveyor belt transports workpieces, the top block moves up and down along the guide groove, which can lift the workpieces on the receiving plate to suspend them in the air and fully expose them to the hot airflow.

[0006] Furthermore, an elastic element is fitted at the lower end of the top block, and the two ends of the elastic element are connected to the top block and the plate, respectively.

[0007] Furthermore, the guide groove includes an inner groove on the upper surface of the receiving plate and a protrusion at the bottom of the inner groove, and the transition between the protrusion and the inner groove is inclined.

[0008] Furthermore, the plate has an opening for the top block to pass through, the opening including a first hole for adapting to the top block and a second hole for accommodating the elastic element.

[0009] Furthermore, the air supply and heating assembly includes an air supply component and a heating component, with the air supply component located above the heating component.

[0010] Furthermore, the heating element includes a mounting plate and a heating tube disposed on the lower end face of the mounting plate.

[0011] Furthermore, the air supply component includes a rotary drive mounted on the top of the furnace body, the output end of which extends into the inner cavity of the furnace body and is equipped with multiple fan blades.

[0012] Furthermore, a telescopic rod is installed at the top of the furnace cavity, and the mounting plate is installed on the telescopic rod.

[0013] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, the operator places the workpiece after spraying glue on the plate chain conveyor belt, and it enters the furnace body with the conveyor belt. The air supply heating component is activated to generate a uniform hot airflow, which blows from top to bottom on the surface of the workpiece to accelerate the curing of the glue layer. When the conveyor belt is running, the top block on the plate moves along the guide groove of the receiving plate. At a specific position, it is lifted upward by the protruding structure of the guide groove, so that it is briefly suspended and separated from the conveyor belt. This action makes the bottom and sides of the workpiece completely exposed to the hot airflow, solving the problem of uneven local heating caused by contact with the conveyor belt in traditional drying methods.

[0014] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0019] Explanation of reference numerals in the attached diagram: Furnace body 10, air supply and heating assembly 11, air supply component 111, rotary driver 1111, fan blade 1112, heating element 112, mounting plate 1121, heating tube 1122, telescopic rod 12; Plate chain conveyor belt 20, plate 21, through 211, first hole 2111, second hole 2112, top block 22, elastic element 23; Receiver plate 30, guide groove 31, inner groove 311, protrusion 312. Detailed Implementation

[0020] Please refer to Figure 1-4As shown, it illustrates the specific structure of a preferred first embodiment of the present invention, which is a drying oven for an automotive product adhesive spraying production line. It includes an oven body 10 and a plate chain conveyor belt 20 passing through the oven body 10. An air-feeding heating component 11 is provided in the upper part of the inner cavity of the oven body 10. The plate chain conveyor belt 20 includes several plates 21, each plate 21 having a movable top block 22. The plate chain conveyor belt 20 has upper and lower layers, with a receiving plate 30 positioned between the upper and lower layers. The receiving plate 30 has a guide groove 31 that cooperates with the top block 22. When the plate chain conveyor belt 20 transports workpieces, the top block 22 moves up and down along the guide groove 31, lifting the workpieces on the receiving plate 30 and suspending them in the air, fully exposing them to the hot airflow. The operator places the workpiece after spraying glue on the plate chain conveyor belt 20, and it enters the furnace body 10 with the conveyor belt. The air supply heating component 11 is activated to generate a uniform hot airflow that blows from top to bottom on the surface of the workpiece to accelerate the curing of the glue layer. When the conveyor belt is running, the top block 22 on the plate 21 moves along the guide groove 31 of the receiving plate 30. At a specific position, it is pushed upward by the protruding structure 312 of the guide groove 31, so that it is briefly suspended and separated from the conveyor belt. This action makes the bottom and sides of the workpiece completely exposed to the hot airflow, solving the problem of uneven local heating caused by contact with the conveyor belt in traditional drying methods.

[0021] For example, an elastic element 23 is sleeved on the lower end of the top block 22, and the two ends of the elastic element 23 are connected to the top block 22 and the plate 21 respectively. The top block 22 can automatically reset under the action of the elastic element 23 to ensure smooth conveying of the workpiece.

[0022] For example, the guide groove 31 includes an inner groove 311 on the upper surface of the receiving plate 30 and a protrusion 312 at the bottom of the inner groove 311, with the transition between the protrusion 312 and the inner groove 311 being inclined. When the plate chain conveyor belt 20 is running, the top block 22 slides along the inner groove 311. When it reaches the protrusion 312, it is guided by the inclined transition section to gradually move upward, smoothly lifting the workpiece. After passing the protrusion 312, the top block 22 is reset under the action of the elastic member 23, and the workpiece falls back onto the conveyor belt, completing a dynamic drying cycle. In addition, the connection between the protrusion 312 and the inner groove 311 adopts a smooth inclined design to avoid rigid impact when the top block 22 moves, ensuring the continuity of lifting and lowering actions.

[0023] For example, the plate 21 has an opening 211 through which the top block 22 passes. The opening 211 includes a first hole 2111 that adapts to the top block 22 and a second hole 2112 that accommodates the elastic member 23. The diameter of the second hole 2112 is larger than that of the first hole 2111, forming a stepped hole structure, which provides sufficient installation and deformation space for the elastic member 23.

[0024] For example, the air supply and heating assembly 11 includes an air supply component 111 and a heating component 112, with the air supply component 111 located above the heating component 112. The air supply component 111 is located above the heating component 112, so that the heat generated when the heating component 112 heats up can be carried away by the airflow generated by the air supply component 111 and form a stable vertical hot air curtain that covers the entire working surface of the conveyor belt.

[0025] For example, the heating element 112 includes a mounting plate 1121 and a heating tube 1122 disposed on the lower end face of the mounting plate 1121. The heating tube 1122 may be an aluminum alloy heating tube.

[0026] The air supply component 111 includes a rotary driver 1111 mounted on the top of the furnace body 10. The output end of the rotary driver 1111 extends into the inner cavity of the furnace body 10 and is equipped with multiple fan blades 1112.

[0027] A telescopic rod 12 is provided at the top of the inner cavity of the furnace body 10, and a mounting plate 1121 is installed on the telescopic rod 12. Adjusting the telescopic rod 12 can adjust the distance between the mounting plate 1121 and the plate body 21 to adjust the heat of the vertical hot air curtain.

[0028] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
