Description

Technical Field

[0001] The utility model relates to the technical field of door cover processing, in particular to a uniform heating device for a door strip forming machine and the door strip forming machine. Background Art

[0002] With increasing demands for aesthetically pleasing interior decoration and a growing focus on environmental performance, paint-free, multi-layer solid wood curved door moldings are gaining market favor due to their excellent decorative effects and environmentally friendly properties. During the door molding production process, to ensure precise bending while maintaining an intact surface, the door strips are typically pre-coated with a protective film and mechanically grooved at predetermined locations. The curved areas are then secured using adhesives such as hot melt adhesive and a door molding machine. Heating and insulation are crucial in this process, directly affecting the hot melt adhesive's fluidity and final curing properties, which in turn impacts the quality of the finished product.

[0003] Traditionally, the heating and heat preservation methods used in this type of bending process rely on external heat sources such as heat lamps to transfer heat to the target area through thermal radiation. However, this method has obvious shortcomings:

[0004] Slow heating speed: Since thermal radiation transfers energy indirectly, the heating process takes a long time.

[0005] Poor thermal insulation: Heat is easily lost to the surrounding environment, making it difficult to maintain the required temperature for a long time.

[0006] Low thermal energy utilization rate: A large amount of thermal energy fails to effectively act on the part to be heated, resulting in a waste of resources.

[0007] Uneven heating: Thermal radiation cannot ensure a uniform temperature rise across the entire heated surface, thus affecting the consistency of the final product.

[0008] In view of the above problems, it is particularly important to develop a new heating device that can improve heating efficiency, ensure heating uniformity, reduce energy consumption and is easy to operate. To this end, this application proposes a uniform heating device designed specifically for a door strip forming machine, aiming to overcome the defects in the prior art. Utility Model Content

[0019] Furthermore, it also includes a diverter box, and the two uniform heating devices are arranged in parallel on the frame, and the diverter box and the uniform heating device are connected through a pipeline.

[0020] The beneficial effects of the utility model are:

[0021] 1. Efficient Heating: The uniform heating device of this application can directly blow hot air onto the bend, transferring heat through a combination of heat conduction and convection, greatly improving the heating speed. Compared to traditional heating lamps that rely solely on heat radiation, this method can reach the required operating temperature more quickly, reducing waiting time and improving production efficiency.

[0022] 2. Uniform heating: This device allows the sheet to be heated evenly across the length of the square tube, facilitating bending and deformation, while avoiding local overheating or uneven cooling. This uniform heating helps improve the fluidity of the hot melt adhesive throughout the entire bending area, ensuring consistent and reliable bonding.

[0023] 3. Precise Positioning: The air outlet design allows the hot air to be directed directly at the bend, with precise positioning, concentrating the heat more precisely on the area that needs heating. This not only saves energy but also avoids unnecessary heat loss, ensuring the effectiveness of the heating process.

[0024] 4. Reduce heat loss: Due to the use of direct heating, heat loss to the surrounding air is reduced, and the utilization rate of heat energy is improved. This is not only beneficial to energy conservation and environmental protection, but also reduces production costs.

[0025] 5. Simplified system configuration: Only a single heat source is required at the air inlet on the pole to meet the entire heating demand, which simplifies the complexity of the heating system, reduces maintenance workload, and also reduces equipment investment costs.

[0026] 5. Improve product quality: The uniform and efficient heating process helps to better control the state of the hot melt adhesive, thereby ensuring the tight bonding of the bent part of the door strip and improving the structural strength and appearance quality of the final product.

[0027] 6. Easy to operate: The newly designed heating device has a compact structure, is easy to install, and can be easily integrated into existing production lines.

If the specific posture changes, the directional indications will also change accordingly.

[0039] The utility model provides a uniform heating device for a door strip forming machine and the door strip forming machine.

[0040] In this embodiment, referring to Figure 1-6 The door strip forming machine uses a uniform heating device, which includes a strip-shaped rod 1, the interior of the rod 1 has a hollow air through-hole 2, and the rod is provided with an air inlet 3 connected to the air through-hole, and the side of the rod is provided with an air outlet 4, and the air outlet 4 is provided with a guide mechanism 5, and the guide mechanism 5 is used to guide the wind direction from the air outlet.

[0041] The above technical solution includes a strip-shaped rod with a hollow air hole inside for the circulation of hot air. An air inlet is provided at one end of the rod, connected to the air hole, for receiving hot air generated by an external heat source. Multiple air outlets are opened on the side of the rod, each equipped with a guide mechanism for directing the air outflow (for example, to the bend hot melt adhesive), ensuring that the hot air is blown accurately to the bend to be heated.

[0042] During use, the device is installed on a door strip forming machine, with the air outlet aligned with the bend of the panel to be bent, providing continuous heating. This application provides an efficient and uniform heating method. The guide mechanism ensures that the hot air is concentrated in the bend area, improving heating efficiency. The overall structure is simple, making it easy to install and maintain.

[0043] Specifically, the air through hole is a continuous through hole arranged along the length direction of the rod.

[0044] Air holes are arranged continuously along the length of the rod, forming a channel that runs through the entire rod. This ensures that hot air can flow smoothly from one end to the other, resulting in even distribution across the entire length. This ensures uniform distribution of hot air within the rod, preventing localized overheating. This allows the entire rod to serve as an effective heating area, improving heating coverage.

[0045] Specifically, the air inlet is connected to an air inlet butt joint 6 .

[0046] The air inlet is designed to connect to an air inlet butt-joint pipe, allowing for easy connection to an external hot air source, such as a hot air blower, ensuring smooth flow of hot air into the pole. This simplifies connection to the external heat source and facilitates installation and removal, ensuring a stable supply of hot air and improving controllability of the heating process.

[0047] Specifically, the guide mechanism includes a connecting plate 7 connected to the bottom of the rod, a guide plate 8 connected to the connecting plate, and a surrounding plate 9 arranged on both ends of the guide plate. A blowing opening 10 is formed between the guide plate, the surrounding plate and the side wall of the rod where the air outlet is provided.

[0048] The guide mechanism can precisely control the direction of hot air flow, making it more concentrated on the bend, thus enhancing the heating effect and reducing heat waste.

[0049] Specifically, there are multiple air outlets, which are arranged at intervals on the side of the rod.

[0050] Multiple air outlets are located on the side of the rod, spaced apart along its length. This allows hot air to reach the bend at multiple points simultaneously, improving heating uniformity. The number and location of the outlets can be adjusted to accommodate door strips of varying sizes and shapes.

[0051] Specifically, the guide mechanism surrounds at least one air outlet.

[0052] It ensures that each air outlet can play its due role, reduces heat loss and improves energy utilization.

[0053] Specifically, the bottom of the connecting plate is provided with a U-shaped groove 11, and the bottom of the rod is provided with a fixing hole 12.

[0054] There is a U-shaped groove at the bottom of the connecting plate, and a fixing hole is provided at the corresponding position at the bottom of the rod. The two are used together to conveniently fix the guide mechanism on the rod.

[0055] Specifically, the upper side of the rod portion has a supporting plane 13 .

[0056] A support surface is provided on the upper side of the rod to support the door strip to be bent, ensuring a smooth placement on the heating device. This support surface provides a stable platform for the door strip, facilitating handling during the heating process. This helps maintain the door strip's flatness during heating, improving the quality of the finished product.

[0057] The present application also provides a door strip forming machine, including a frame 14, a folding mechanism 15 and a uniform heating device, wherein the folding mechanism is arranged on both sides of the frame, the uniform heating device is arranged between the two folding mechanisms, and the plate to be bent is laid on the supporting plane of the uniform heating device.

[0058] The door strip forming machine consists of a frame, a folding mechanism, and the aforementioned uniform heating device. The folding mechanisms are located on either side of the frame, while the uniform heating device is located between the two folding mechanisms. The door strip (the sheet to be bent) is placed on the support surface of the uniform heating device for heating and subsequent bending. The integrated high-efficiency heating device improves the operating efficiency of the entire forming machine.

[0059] Specifically, it further includes a diverter box, and the two uniform heating devices are arranged in parallel on the frame. The diverter box and the uniform heating device are connected through a pipeline.

[0060] The door strip forming machine also includes a diverter box 16, and two uniform heating devices are arranged in parallel on the frame. The diverter box is connected to the uniform heating device through a pipeline and is responsible for evenly distributing the hot air to the two heating devices.
