Description

Technical Field

[0001] This utility model application relates to the field of polyurethane foam technology, specifically an oven for using environmentally friendly polyurethane foam adhesive in wall panel bonding. Background Technology

[0002] Polyurethane foam is a single-component or two-component polymeric foam material with polyurethane prepolymer as the main component. It expands and cures through a chemical reaction, forming a closed-cell or open-cell foam structure with bonding, sealing, filling and thermal insulation functions. Its characteristics include high expansion rate, excellent adhesion, low thermal conductivity and good waterproof and shockproof performance. According to the application, it can be divided into building joint filling type, pipe insulation type and industrial bonding type; according to the fire rating, it is divided into B1 flame retardant, B2 flame retardant and B3 ordinary grade. It is widely used in building joint sealing, door and window installation, cold chain insulation and automobile manufacturing and other fields. It needs to be used with a special glue gun during construction. After curing, it has the characteristics of secondary processing such as sanding and painting.

[0003] To improve the adhesion of polyurethane foam, high-viscosity polyols or isocyanates are often added. To ensure the fluidity of these materials during use, they often need to be preheated in an oven. However, traditional ovens often use a layered structure, which leads to inefficient use of space. Furthermore, materials at the bottom of the oven tend to reach the target temperature faster, thus affecting the optimal usage time of the materials. Summary of the Invention

[0004] To address the problems of traditional layered ovens failing to effectively utilize space and inconsistent baking times for raw materials in different locations, this invention provides an environmentally friendly oven for bonding polyurethane foam to wall panels, thus solving the aforementioned issues.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An oven for bonding environmentally friendly polyurethane foam to wall panels includes an oven shell with a sealed door at the front end. A fan is fixed to the bottom inside the oven shell, and several heating tubes are fixed to the rear end inside the oven shell. Two rotating disks are symmetrically rotatably connected to the upper part of the oven shell, and a connecting rod is fixed between the two rotating disks. A servo motor is fixed to one side of the outside of the oven shell, and the output end of the servo motor is fixedly connected to one of the rotating disks. Several support rods are symmetrically fixed between the two rotating disks, and two mounting sliders are movably mounted on each support rod. A hook is rotatably connected to the bottom end of each mounting slider.

[0007] Furthermore, each of the support rods is symmetrically rotatably connected to two limiting plates, a lead screw is provided above the support rod, the lead screw is rotatably connected to the two limiting plates, a control wheel is fixed in the middle of the lead screw, the control wheel is located between the two limiting plates, and the lead screw is threadedly connected to the mounting slider.

[0008] Furthermore, an observation window is provided at the front end of the oven shell, and air inlets that cooperate with the fan are provided on the lower sides of the oven shell.

[0009] Furthermore, the fan is located directly below the rotating disk, and the height of the rotating disk is greater than two-thirds of the internal height of the oven shell.

[0010] Furthermore, the screw threads at both ends of the control wheel are in opposite directions, and the length of the screw is less than the length of the support rod.

[0011] Furthermore, the limiting plate is located at the center of the support rod, and the length between the two limiting plates is the same as the length of the control wheel.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, a servo motor drives a rotating disk to rotate, which in turn drives a support rod to rotate. This causes the support rod to rotate the raw materials hanging on the mounting slider, ensuring that the baking time of the raw materials on each support rod inside the oven is uniform. The rotation method also makes it easier for workers to load materials, solving the problems of traditional layered ovens not being able to effectively utilize space and the unstable baking time of raw materials in different positions.

[0014] 2. In this utility model, a limiting plate is rotatably set on the support rod, and a lead screw is rotatably set inside the limiting plate. The operator controls the lead screw to rotate through the control wheel, which in turn causes the lead screw to drive the hanging slider to slide on the support rod. This makes it easy to adjust the position of the two hooks, solving the problem that when the container for holding raw materials is large, a single hook cannot effectively hang the load and two hooks are needed to hang the load together.

[0021] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 An oven for bonding environmentally friendly polyurethane foam to wall panels includes an oven shell 1, a sealed door 2 at the front end of the oven shell 1, a fan 4 fixed at the bottom inside the oven shell 1, several heating tubes 5 fixed at the rear end inside the oven shell 1, two rotating disks 6 symmetrically rotatably connected to the upper part inside the oven shell 1, a connecting rod 7 fixed between the two rotating disks 6, a servo motor 8 fixed to one side of the outside of the oven shell 1, the output end of the servo motor 8 fixedly connected to one of the rotating disks 6, several support rods 9 symmetrically fixed between the two rotating disks 6, two hanging sliders 10 movably mounted on each support rod 9, and a hook 11 rotatably connected to the bottom end of each hanging slider 10, so that the servo motor 8 drives the container inside the oven shell 1 to rotate and bake evenly.

[0023] Specifically, an observation window 3 is provided at the front end of the oven shell 1, and air inlets 15 are provided on the lower sides of the oven shell 1 to cooperate with the fan 4. The fan 4 is located directly below the rotating plate 6. The height of the rotating plate 6 is greater than two-thirds of the internal height of the oven shell 1, so as to avoid the rotating plate 6 from easily moving to the bottom of the oven shell 1 and colliding with it.

[0024] As an optimization solution, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, each support rod 9 is symmetrically rotatably connected to two limiting plates 13. A lead screw 12 is provided above the support rod 9. The lead screw 12 is rotatably connected to the two limiting plates 13. A control wheel 14 is fixed in the middle of the lead screw 12. The control wheel 14 is located between the two limiting plates 13. The lead screw 12 is threadedly connected to the hanging slider 10, so that the distance between the two hooks 11 can be adjusted.

[0025] Specifically, the screws 12 at both ends of the control wheel 14 have opposite thread directions, the length of the screw 12 is less than the length of the support rod 9, the limiting plate 13 is located at the center of the support rod 9, and the length between the two limiting plates 13 is the same as the length of the control wheel 14, making it easier for the operator to rotate the screw 12.

[0026] Working principle: The worker opens the sealed door 2, and then, according to the required container volume, selects to rotate the control wheel 14. The control wheel 14 drives the lead screw 12 to rotate, which in turn drives the hanging slider 10 to slide on the support rod 9. Simultaneously, the hanging slider 10 moves the hook 11, allowing the worker to move the hook 11 to the designated position and hang the container on it. At the same time, the servo motor 8 is activated, causing the rotating disk 6 to rotate. This rotating disk 6 then moves the support rod 9, simultaneously moving another support rod 9 in front of the worker. The staff hangs another container on another hook 11 using the above method. When the support rod 9 moves, the container moves the hook 11 under the action of gravity. At the same time, the hook 11 drives the hanging slider 10 to rotate on the support rod 9. The hanging slider 10 also drives the limiting plate 13 to rotate on the support rod 9. After the staff finishes hanging the container, they start the fan 4 and the heating tube 5 to heat the inside of the oven shell 1. At the same time, the fan 4 improves the baking efficiency inside the oven shell 1 through airflow. At this time, the staff can observe the baking progress inside the oven shell 1 through the observation window 3.
