Description

Technical Field

[0001] This utility model relates to the field of edge banding technology for sheet metal, specifically a hot bending device for edge banding strips in louver processing. Background Technology

[0002] In the manufacturing of louvers, the hot bending process of the edge banding is a key technology. It is mainly used to make the edge banding fit the curved corners or irregular structures of the louver frame, thereby improving the product's aesthetics, sealing, and durability.

[0003] Traditional edge banding machines typically bond edge banding strips to profiles by heating an adhesive. While edge banding strips have a certain degree of elasticity, making them adaptable to different profile shapes, the uneven stress distribution within the strip causes it to spring back. When the adhesive fails, the edge banding strip can easily separate from the profile and detach at bends. Utility Model Content

[0004] The purpose of this utility model is to provide a hot bending device for edge banding strips in louver processing. By reheating the profile that has already been edge-banded by an edge banding machine, the edge banding strip is softened at high temperature, eliminating the internal stress of the edge banding strip. Then, the edge banding strip is shaped by cooling, so that the edge banding strip fits the profile better and is less likely to separate and fall off, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot bending device for edge banding in louver processing, comprising: Baking oven; The baking oven has fixed frames on both sides. The fixed frames and the inner cavity of the baking oven are rotatably connected by bearings to conveying rollers for conveying louver profiles. The fixed frames and the outer side of the baking oven are provided with drive components for driving the conveying rollers. The oven is equipped with a heating frame inside the cavity, and an electric heating wire is installed inside the heating frame. The oven is also equipped with a heat circulation component for guiding hot air.

[0006] Preferably, the baking oven includes a base frame and a top cover. The top cover is hinged to the top of the base frame and is connected to the base frame. The base frame has inlet and outlet ports on both sides.

[0007] Preferably, the drive assembly includes a fixed box fixed to the base frame and the side of the fixed frame. The inner cavity of the fixed box is rotatably connected to a drive shaft via a bearing. Multiple sets of drive bevel gears are fixed on the drive shaft. One end of the conveying roller passes through the inner cavity of the fixed box and is fixed with a driven bevel gear meshing with the drive bevel gear. One end of the fixed box is fixed with a drive motor that drives the drive shaft.

[0008] Preferably, the thermal circulation assembly includes an air circulation pump fixed on the outer wall of the top cover. The air inlet of the air circulation pump is connected to an air inlet pipe. The end of the air inlet pipe away from the air circulation pump extends from the top of the top cover to the inner side of the top cover. A flow divider is fixed in the inner cavity of the base frame. Multiple sets of nozzles are connected to the inner side of the flow divider. The flow divider is connected to the air outlet of the air circulation pump through an air outlet pipe.

[0009] Preferably, a connecting spring is fixed at each of the four corners of the heating frame, and the end of the connecting spring away from the heating frame is fixed to the inner wall of the base frame.

[0010] Preferably, the outer side of the drive shaft is rotatably connected to multiple sets of support plates via bearings, and the support plates are fixed in the inner cavity of the fixed box.

[0011] Preferably, a temperature sensor is fixed on the inner wall of the base frame, and a PLC controller is provided on the outer side of the baking oven.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a drive assembly to drive a conveyor roller to transport the profile, allowing the profile with the edge banding strip to enter the baking oven. Then, with the help of a heat circulation assembly, the edge banding strip is subjected to concentrated heating treatment, softening it at high temperature. The softened edge banding strip then fits the profile better, thereby eliminating internal stress. After the profile is removed from the baking oven, the edge banding strip hardens again under natural cooling, making it fit the profile even better and less prone to deformation and detachment.

[0013] This invention places the heating frame above the distribution frame, which not only allows the heat generated by the electric heating wire to accumulate more quickly inside the top cover, providing a high-temperature environment for the baking oven, but also allows hot air to be sprayed outward from the nozzle along with the heat circulation component, concentrating the heat and facilitating the softening of the edge sealing strip.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides, for example Figures 1-5 The louver edge banding hot bending device shown includes: Baking oven 1; The baking oven 1 is fixed with fixed frames 2 on both sides. The fixed frames 2 and the inner cavity of the baking oven 1 are rotatably connected by bearings to conveying rollers 3 for conveying louver profiles. The fixed frames 2 and the outer side of the baking oven 1 are provided with drive components 4 for driving the conveying rollers 3. The oven 1 is equipped with a heating frame 5 inside the cavity, and an electric heating wire 6 is installed inside the heating frame 5. The oven 1 is also equipped with a heat circulation component 7 for guiding hot air. The profile is conveyed by the conveying roller 3 driven by the drive component 4, so that the profile with the edge banding strip enters the baking oven 1. Then, with the cooperation of the heat circulation component 7, the edge banding strip is subjected to centralized heating treatment, so that the edge banding strip is softened at high temperature. Then, the softened edge banding strip fits the profile better, thereby eliminating the internal stress of the edge banding strip. Afterwards, the profile is removed from the baking oven 1, and under natural cooling, the edge banding strip hardens again, and its shape fits the profile better, making it less likely to deform and fall off.

[0018] Among them, such as Figure 4 As shown: The baking oven 1 includes a base frame 101 and a top cover 102. The top cover 102 is hinged to the top of the base frame 101 and is connected to the base frame 101. The base frame 101 has inlet and outlet ports on both sides. By designing the structure of the baking oven 1, it is convenient to open the top cover 102 from the top of the base frame 101, which facilitates the maintenance of the equipment inside the baking oven 1.

[0019] Furthermore, such as Figure 3 As shown: The drive assembly 4 includes a fixed box 41 fixed to the side of the base frame 101 and the fixed frame 2. The inner cavity of the fixed box 41 is rotatably connected to the drive shaft 42 via bearings. Multiple sets of drive bevel gears 43 are fixed on the drive shaft 42. One end of the conveying roller 3 passes through the inner cavity of the fixed box 41 and is fixed with a driven bevel gear 44 meshing with the drive bevel gear 43. One end of the fixed box 41 is fixed with a drive motor 45 that drives the drive shaft 42. The drive motor 45 drives the drive shaft 42 to rotate, and then the drive shaft 42 drives the drive bevel gear 43 to rotate. The driven bevel gear 44 synchronously drives the conveying roller 3, which facilitates the transfer of the profile placed on the conveying roller 3, allowing it to enter from one side of the baking oven 1 and exit from the other side.

[0020] Preferred, such as Figure 4-5 As shown: The heat circulation assembly 7 includes an air circulation pump 71 fixed on the outer wall of the top cover 102. The air inlet of the air circulation pump 71 is connected to an air inlet pipe 72. The end of the air inlet pipe 72 away from the air circulation pump 71 passes through the top of the top cover 102 to the inner side of the top cover 102. A diversion frame 73 is fixed in the inner cavity of the base frame 101. The inner side of the diversion frame 73 is connected to multiple sets of nozzles 74 through a corrugated pipe. The diversion frame 73 is connected to the air outlet of the air circulation pump 71 through an air outlet pipe 75. The air outlet pipe 75 is a high-temperature resistant flexible hose. The air circulation pump 71 draws hot air from the top cover 102 into the diversion frame 73 through the air inlet pipe 72 and the air outlet pipe 75. Then, the hot air is sprayed outward from the nozzles 74, whose angle can be adjusted at will, to rapidly heat up the edge sealing strip area, ensuring that the edge sealing strip is completely softened, while not affecting the temperature change of the profile.

[0021] It is worth noting that, such as Figure 2 As shown: Connecting springs 8 are fixed at the four corners of the heating frame 5. The end of the connecting spring 8 away from the heating frame 5 is fixed to the inner wall of the base frame 101. The setting of the connecting spring 8 facilitates the connection of the heating frame 5 and at the same time provides vibration buffer for the electric heating wire 6 to avoid vibration causing the electric heating wire 6 to break.

[0022] In a further preferred embodiment, such as Figure 3 As shown: Multiple sets of support plates 9 are rotatably connected to the outer side of the drive shaft 42 via bearings. The support plates 9 are fixed in the inner cavity of the fixed box 41. The support plates 9 are designed to limit the drive shaft 42 and prevent the drive shaft 42 from being too long and causing it to shake during rotation, which would affect the meshing of the drive bevel gear 43 and the driven bevel gear 44.

[0023] In addition, such as Figure 1 and Figure 4 As shown: A temperature sensor 10 is fixed on the inner wall of the base frame 101, and a PLC controller 11 is set on the outside of the baking oven 1. By setting the temperature sensor 10, it is convenient to monitor the temperature inside the baking oven 1 in real time. Then, the PLC controller 11 can control the electric heating wire 6 and the drive motor 45 to regulate the temperature and the speed of the drive roller.

[0024] In practical use, the drive motor 45 and the electric heating wire 6 are started by the PLC controller 11. The electric heating wire 6 heats the air in the baking oven 1 based on the data feedback from the temperature sensor 10. Then, the profile sealed by the edge banding machine is placed on the conveyor roller 3. The drive motor 45 drives the drive shaft 42 to rotate. With the cooperation of the drive bevel gear 43 and the driven bevel gear 44, the conveyor roller 3 is rotated, transferring the profile into the baking oven 1. At the same time, the air circulation pump 71 draws the hot air out of the top cover 102 and introduces it into the diversion frame 73 from the air outlet 75. Then, it is sprayed outward from the nozzle 74. The hot air sprayed from the nozzle 74 rapidly heats up the edge banding strip on the profile, making it soften quickly. The edge banding strip adheres to the profile, eliminating internal stress. After the profile is removed from the baking oven 1, the edge banding strip cools naturally and is then reshaped and adhered to the outside of the profile.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
