[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0021] See also Figure 1-Figure 4 A workpiece preheating mechanism for a PUR edge banding glue machine comprises a box body 1 and a box door 2 hinged on one side of the box body 1, a heating chamber 101 is opened on one side of the box body 1 close to the box door 2, heating plates 3 are fixedly connected to both sides of the inner wall of the heating chamber 101, a rotating mechanism is connected to the upper surface of the outer wall of the box body 1, the other end of the rotating mechanism passes through the outer wall of the box body 1 and is connected to four connecting rods 7, the other ends of the four connecting rods 7 are also fixedly connected to a partition net 6, the bottom surface of the partition net 6 is connected to a supporting assembly, and the bottom surface of the supporting assembly is connected to the bottom surface of the heating chamber 101.
[0022] The PUR edge banding machine workpiece preheating mechanism in the utility model is similar to the existing edge banding machine workpiece preheating mechanism structure, such as the edge banding machine heating device disclosed in the patent with publication number CN220094912U. The main improvement of the utility model is that when the user preheats the workpiece through the edge banding machine box 1, the workpiece located between the connecting rod 7 and the partition 6 can be driven to rotate by the rotating mechanism, thereby making the workpiece heating and drying effect more uniform and faster, thereby improving work efficiency. Figures 1 to 4As shown, when the workpiece preheating mechanism of the PUR edge banding glue machine in the utility model is in use, first the workpiece to be preheated is placed above the partition net 6 and between the four connecting rods 7, then the box door 2 is closed, and then the heating plate 3 and the rotating mechanism are opened by an external controller. After the heating plate 3 is started, it will continuously release heat to the outside, thereby rapidly increasing the temperature inside the heating chamber 101. At the same time, after the rotating mechanism is started, it starts to drive the four connecting rods 7 and the partition net 6 to rotate, so that the four sides of the workpiece located on the four connecting rods 7 and the partition net 6 can be sequentially close to the heating plates 3 on both sides, thereby making the workpiece heated more evenly and faster, thereby improving work efficiency.
[0023] It should be specially explained here that the heating plate 3 is a general term for existing items that can provide heating effect, and here it can refer to a plate that has its own heating effect, such as a heating wire installed inside; it can also refer to the effect of transferring heat to the inside of the heating chamber 101 through this after being connected to an external heating mechanism, thereby heating the workpiece inside the heating chamber 101, without specific limitation.
[0024] Another point that needs to be emphasized is that the controller is a very mature technology in the existing technology, so it is not described in detail.
[0025] Please refer to Figure 1 , Figure 2 and Figure 4 The rotating mechanism includes a motor 4 and a top plate 10. The outer wall of the motor 4 is fixedly connected to the upper surface of the outer wall of the box body 1. The output shaft of the motor 4 passes through the outer wall of the box body 1 and is fixedly connected to the upper surface of the top plate 10. The upper surface of the top plate 10 is rotatably connected to the top surface of the heating chamber 101. The bottom surface of the top plate 10 is fixedly connected to one end of the four connecting rods 7 away from the partition net 6.
[0026] More specifically, when the workpiece begins to be preheated, the motor 4 is first started through an external controller. After the motor 4 is started, the output shaft drives the top plate 10 to rotate. After the top plate 10 rotates, it drives the four connecting rods 7 below to rotate, and then drives the partition net 6 to rotate, so that the tools placed on the partition net 6 can be rotated and preheated, making the heating more uniform.
[0027] Please refer to Figure 1 , Figure 2 and Figure 4 , four connecting rods 7 are respectively located at the four corners of the top plate 10 and the partition net 6. By arranging the four connecting rods 7 at the four corners of the top plate 10 and the partition net 6, the support can be made more stable.
[0028] Please refer to Figure 3 and Figure 4The bottom surface of the heating chamber 101 is provided with a rotation groove 102, and the end of the support assembly away from the partition 6 is located inside the rotation groove 102. By setting the rotation groove 102, firstly, a limit can be given to the support assembly to prevent the support assembly from shaking inside the heating chamber 101; secondly, when the support assembly rotates with the motor 4, a sliding track can be given to the support assembly.
[0029] Please refer to Figure 1-Figure 4 The supporting assembly includes a support plate 5, a plurality of support rods 8 and a turntable 9. The upper surface of the support plate 5 is fixedly connected to one end of the partition net 6 away from the connecting rod 7. The bottom surface of the support plate 5 is fixedly connected to the upper surfaces of the plurality of support rods 8. The other ends of the plurality of support rods 8 are fixedly connected to the upper surface of the turntable 9. The turntable 9 is located in the rotating groove 102, and the outer wall of the turntable 9 is slidably connected to the inner wall of the rotating groove 102.
[0030] More specifically, when the motor 4 drives the partition net 6 to rotate, the partition net 6 will also drive the support plate 5 to rotate, and then can drive several support rods 8 and the turntable 9 to rotate at the same time. Because the turntable 9 is in the rotating groove 102, it can rotate without affecting the rotation and will not fall off or shake.
[0031] Please refer to Figure 1 , Figure 2 and Figure 4 The partition net 6 and the four connecting rods 7 form a group, and a plurality of groups of partition nets 6 and four connecting rods 7 are arranged inside the heating chamber 101, and two adjacent groups of partition nets 6 and four connecting rods 7 are fixedly connected. By arranging a plurality of groups of partition nets 6 and four connecting rods 7, when preheating the workpieces, a plurality of workpieces can be preheated at the same time.
[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
