Description

Technical Field

[0001] This utility model relates to the technical field of fabric heating equipment, and in particular to a heating device for a tenter frame. Background Technology

[0002] In traditional tenter frame machines, the fabric heating process mainly relies on hot air heating devices to achieve fabric drying and setting. Most existing heating devices use electric heating, steam, or gas to heat the air, and then transport the hot air through air ducts.

[0003] However, due to uneven airflow distribution, temperature fluctuations occur during heat transfer, which may lead to uneven heating of the fabric and even damage to the fabric surface. This is especially true when processing delicate or heavy fabrics, where localized overheating or underheating can easily occur. This phenomenon not only affects production efficiency but also reduces product quality.

[0004] To improve heating efficiency and uniformity, existing technologies have proposed incorporating different airflow guidance designs into hot air heating systems. However, these solutions cannot effectively address the issues of airflow unevenness and heat energy waste. Furthermore, the hot airflow has a certain velocity during drying, and different types of fabrics often require avoiding direct contact between excessively fast airflow and the fabric surface. When dealing with the heating requirements of different types of fabrics, these solutions lack flexible control capabilities and cannot separate heating zones for flexible feeding adjustments. This results in suboptimal temperature control and airflow distribution during the heating process, and makes it difficult to recover and regulate excess heat energy. Utility Model Content

[0005] The purpose of this invention is to address the deficiencies in the existing technology by proposing a heating device for a tenter frame.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A heating device for a tenter frame includes a frame with conveying ports on all four side walls. Each conveying port is fitted with a baffle plate. Inside the frame are a heat source frame and several flow-guiding heating mechanisms. The heat source frame is symmetrically distributed vertically. Several power pumps are located on one side of the heat source frame. Connecting pipes connected to the flow-guiding heating mechanisms are provided on the heat source frame. A support shaft that cooperates with the frame is located at the center of each flow-guiding heating mechanism. A mounting connecting sleeve is provided between the flow-guiding heating mechanism and the support shaft.

[0008] Furthermore, the two support shafts are connected by a coupling bracket mounted on the frame, which is used to enable the two connected support shafts to rotate in the same or opposite directions.

[0009] Several transition pipes are provided between the two heat source racks, and the transition pipes are equipped with switch valves.

[0010] Furthermore, the flow guiding heating mechanism includes a flow guiding shell and a plurality of flow guiding plates, the flow guiding plates being evenly distributed on the inner wall of the flow guiding shell, and the flow guiding plates being connected to the mounting connecting sleeve by a plurality of support rods;

[0011] The air guide shell has several air outlets that cooperate with the air guide plate.

[0012] Furthermore, both ends of the flow guide housing are provided with rotating plates that are connected to the connecting pipeline, and the rotating plates are connected to the mounting connecting sleeve by bearings.

[0013] Furthermore, the guide plate has an arc-shaped structure, one end of the guide plate is connected to the guide shell, and the other end forms a guide port with the inner wall of the adjacent guide plate, and the tangential direction of the guide plate is inclined to the tangent of the guide shell.

[0014] Furthermore, a guide wall is provided on one side of the air outlet, and the gap between the guide wall and the outer wall of the air guide housing is greater than the minimum distance of the air outlet.

[0015] Furthermore, a cutting frame that cooperates with the flow guide housing is provided on one side of the guide wall. The cutting frame is provided with a plurality of evenly distributed cutting guide plates, and the cutting guide plates are connected to the cutting frame by adjusting bolts.

[0016] Furthermore, the cutting guide plate is a triangular structure with an arc on one side wall, and the cutting guide plate is distributed along the air outlet array, and is evenly arranged from high to low from the middle position to both sides.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] Fabric heating is achieved by using a symmetrically distributed heat source and a flow-guiding heating mechanism. The flow-guiding heating mechanism can achieve precise airflow guidance and distribution, so that the hot airflow is evenly distributed on the fabric surface. The rotation design of the flow-guiding heating mechanism effectively disperses the high-pressure and high-speed airflow, maintaining a stable flow velocity during the heating and exhaust process. This avoids the airflow velocity being too fast and directly impacting local areas of the fabric, allowing different areas to experience different hot airflows. This makes the flow of hot airflow inside the flow-guiding shell more stable, avoiding violent fluctuations in hot airflow and ensuring temperature uniformity during the heating process.

[0019] By setting up transition pipes and a reverse rotation structure, hot airflow can be recycled, reducing energy waste. The connection between heat source racks and the airflow recycling design not only effectively maintain the temperature stability inside the heating zone, but also reduce heat energy consumption.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Reference Figure 1-5The heating device of the tenter frame includes a frame 1. Each of the four side walls of the frame 1 is provided with a conveying port 2. A baffle plate 3 is installed on the conveying port 2. The interior of the frame 1 is provided with a heat source frame 4 and several flow guiding heating mechanisms 5. The heat source frame 4 is symmetrically distributed vertically inside. Several power pumps 6 are provided on one side of the heat source frame 4. It should be noted that the heat source frame 4 has a rectangular shell structure. The heat source frame 4 is equipped with several electric heating elements such as electric heating tubes, heaters or electric heating wires to provide a heat source and heat the internal space of the heat source frame 4. The power pump 6 generates airflow and delivers the heated gas to the flow guiding heating mechanism 5 or other places.

[0030] The heat source frame 4 is equipped with a connecting pipe 7 that is connected to the flow guiding heating mechanism 5. The power pump can connect one or more connecting pipes 7 by adding a main pipe, and each power pump can independently deliver and output to one or more connecting pipes.

[0031] The flow guiding heating mechanism 5 has a support shaft 8 that cooperates with the frame 1 at the middle position. A motor is installed at the connection between the frame 1 and the support shaft 8 to provide a power source for the support shaft 8.

[0032] An installation connecting sleeve 14 is provided between the flow guiding heating mechanism 5 and the support rotating shaft 8. The installation connecting sleeve is used to install different numbers of flow guiding heating mechanisms 5 at different positions on the support rotating shaft 8 to separate different heating areas. The fabric enters from the bottom of the flow guiding heating mechanism 5 or between two flow guiding heating mechanisms 5 distributed vertically, and leaves the frame 1 after being heated, thus completing the heating process. The flow guiding heating mechanism 5 and the heat source frame 4 are both symmetrically distributed vertically. Depending on the different heating requirements of the fabric, the fabric can be heated by entering and exiting in a direction perpendicular to the axis of the flow guiding heating mechanism 5 or by entering and exiting in a direction parallel to the axis of the flow guiding heating mechanism 5.

[0033] The two supporting shafts 8 are connected by a coupling frame 9, which is mounted on the frame 1. The coupling frame 9 is used to make the two connected supporting shafts 8 rotate in the same direction or in opposite directions. The opposite rotation is achieved by installing a coaxial opposite rotation structure inside the coupling frame 9 to connect two identical gear disks to the supporting shafts 8, and the rotation in opposite directions is achieved by bevel gears.

[0034] Coaxial rotation is achieved by installing a coaxial rotating structure coupling inside the coupling frame 9.

[0035] Several transition pipes 10 are provided between the two heat source racks 4. Switch valves are provided on the transition pipes 10. The transition pipes 10 can connect the two heat source racks 4 and circulate the hot air, so that the part covered by the heat source racks 4 can be indirectly heated, so that the heating space inside the rack 1 will not have large temperature changes.

[0036] Reference Figure 1-5 In a specific embodiment of this application, the flow guiding heating mechanism 5 includes a flow guiding shell 11 and a plurality of flow guiding plates 12. The flow guiding plates 12 are evenly distributed on the inner wall of the flow guiding shell 11. The flow guiding plates 12 are connected to the mounting connecting sleeve 14 through a plurality of support rods 13. The support rotating shaft 8 drives the flow guiding shell 11 to rotate through the mounting connecting sleeve 14.

[0037] Both ends of the flow guide housing 11 are provided with rotating plates 16 connected to the connecting pipe 7. The rotating plates 16 and the mounting connecting sleeve 14 are connected by bearings. The rotation of the flow guide housing 11 will not cause the rotating plates 16 to rotate synchronously, so that the heat source frame 4 can continuously receive airflow through the connecting pipe 7 and ensure that the airflow intake direction remains unchanged.

[0038] The air guide housing 11 is provided with several air outlets 15 that cooperate with the air guide plate 12. The air guide plate 12 is used to guide the hot airflow to the air outlets 15 and discharge the airflow from the air outlets 15. Because the air guide plate 12 is connected by the support rod 13 and rotates continuously, the hot airflow will be dispersed by the support rod 13 during the process from the inside of the air guide housing 11 to the discharge. The hot airflow enters the interior through the connecting pipe 7. The airflow direction of the connecting pipe 7 is the same as the axis of the air guide housing 11. The high-pressure and high-speed airflow will not be discharged directly from the air outlets 15, but will be dispersed and guided before being discharged, so as to avoid damage to the fabric due to the excessively fast airflow velocity of the hot air.

[0039] The guide plate 12 has an arc-shaped structure. One end of the guide plate 12 is connected to the guide shell 11, and the other end forms a guide port with the inner wall of the adjacent guide plate 12. The tangential direction of the guide plate 12 is inclined to the tangent of the guide shell 11.

[0040] A guide wall 17 is provided on one side of the air outlet 15. The gap between the guide wall 17 and the outer wall of the guide housing 11 is greater than the minimum distance between the air outlet 15. Because the guide plate 12 has an arc-shaped structure, after being tilted along the tangent, several guide plates 12 will form a spiral structure. After the guide housing 11 drives the guide plate 12 to rotate, clockwise rotation and counterclockwise rotation can respectively achieve adjustments such as exporting internal airflow or importing external airflow. When exporting airflow, the internal hot airflow can be cut and guided, and pressure equalization is achieved according to the set air outlet mode of the air outlet 15. To achieve uniform heating, the airflow is introduced by rotating in the opposite direction to the output. Similarly, the airflow enters the interior of the guide housing 11 through the same route. The airflow collected in the opposite direction is then output to the heat source rack 4 or other locations via the power pump 6 and the connecting pipe 7, realizing the circulation, recovery and reuse of heat flow. During this process, the stability of the area at the position of the reverse rotating guide heating mechanism 5 will be reduced, achieving a temperature difference between different heating division areas, reducing the instantaneous temperature of the fabric surface space, and enabling fine-tuning while keeping the heating parameters constant.

[0041] A cutting frame 18 is provided on one side of the guide wall 17 to cooperate with the flow guide housing 11. The cutting frame 18 is provided with several evenly distributed cutting guide plates 19, and the cutting guide plates 19 are connected to the cutting frame 18 by adjusting bolts.

[0042] The cutting guide plate 19 is a triangular structure with an arc on one side wall. The cutting guide plate 19 is distributed in an array along the air outlet 15, and is evenly arranged from high to low from the middle position to both sides. It is easy to see from the above design that the distribution array of the cutting guide plate 19 can guide the direction of the gas flow from the air outlet 15, so that the air flow can flow in the set direction. Before and after implementation, the installation angle of the cutting guide plate 19 can be adjusted by adjusting the bolts, so that the final air outlet direction is not limited to a fixed direction and can adapt to more operating environments and needs.

[0043] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
