Description

Technical Field

[0001] This invention relates to the field of combustion technology for stenters, specifically to an indirect combustion system for stenters. Background Technology

[0002] A tenter frame is a type of textile machinery primarily used for stretching and setting fabrics; it's an essential piece of equipment in every printing and dyeing factory. It heats air using heat sources such as heat transfer oil, steam, or natural gas, and a fan blows the heated air onto the fabric surface through an air spray box. The normal operating temperature inside the tenter frame's oven is generally 130–230℃. The fabric passes through the oven, taking approximately 15–90 seconds depending on the fabric type. During this process, the fabric evaporates moisture, and the fibers shrink and solidify to achieve the stretching and setting purpose. To effectively achieve these goals, the tenter frame needs to be equipped with a corresponding indirect combustion system.

[0003] However, in actual operation, the existing indirect combustion system of the stenter often results in low heat dissipation efficiency and high gas consumption due to the fact that most of the indirect combustion coils are connected to the outside of the oven to discharge unburned gas. This leads to higher user operating costs. At the same time, the limited hot air spray area of ​​the traditional combustion method can cause uneven temperature inside the combustion chamber. When excessively hot air blows onto the fabric surface, it can cause the fabric to turn yellow. In addition, during long-term transportation, the edges of the fabric surface are prone to wrinkles due to various external factors, which affects the drying effect of the fabric and reduces the stability of the entire processing. Summary of the Invention

[0004] To address the problems in the prior art, the present invention provides an indirect combustion system for a stenter.

[0006] The suction mechanism includes a mounting frame, a ventilation frame is fixedly connected to one side of the mounting frame, a breathable mesh is provided on the ventilation frame, a circulating fan body is provided inside the mounting frame, a filter screen is installed inside the mounting oven, and the filter screen is located on one side of the opening of the circulating fan body. A suction hood is provided on the side wall of the ventilation frame near the mounting frame, and the cross-section of the suction hood is funnel-shaped.

[0007] The diversion mechanism includes a guide plate, which is fixedly connected inside the vent frame. The guide plate has a V-shaped cross-section. A vertical plate is fixedly connected inside the mounting frame. A mesh is provided on the vertical plate. Multiple corrugated pipes are fixedly connected to the vertical plate. The guide plate has multiple through holes, which are arranged in a rectangular array. The corrugated pipes are provided in two groups of multiple pipes, and the multiple corrugated pipes in each group are arranged in an equilateral triangle.

[0008] Specifically, the transmission mechanism includes a support frame, with a support frame fixedly connected to each side of the oven, and a transmission belt body between the two supports. Support legs are fixedly connected to the support frame, and the support legs are generally L-shaped.

[0009] Specifically, the flattening mechanism includes a fixed block, a fixed block is fixedly connected to the top of one side of the support, a handwheel is provided on the fixed block, a lead screw is fixedly connected to the handwheel, the lead screw is rotatably connected to the inside of the fixed block, a movable block is slidably connected inside the fixed block, the lead screw and the movable block are threadedly connected, a flattening roller is rotatably connected to the movable block, and a baffle is fixedly connected to the top of one side of the fixed block, with one end of the baffle being arc-shaped.

[0010] Specifically, the heating mechanism includes a mounting block, which is fixedly connected to the interior of the mounting oven. A spray box body is installed inside the mounting block. The spray box body is provided with multiple nozzle bodies, which extend into the inner cavity of the mounting oven. A pipe connector is fixedly connected to the spray box body, and the air outlet of the circulating fan body is connected to the pipe connector.

[0011] The beneficial effects of this invention are:

[0012] (1) The indirect combustion system of the stenter described in this invention, when in use, the suction mechanism is set on the oven, and the diversion mechanism is set inside the suction mechanism. Through the cooperation of the suction mechanism and the diversion mechanism, the hot air for combustion heating is conveniently diverted and guided, ensuring uniform temperature distribution in all parts of the combustion chamber, avoiding excessive temperature of the fabric due to blowing, reducing yellowing of the fabric surface, and also making the combustion more complete, improving the heat dissipation efficiency of the heat dissipation pipe assembly, and reducing gas consumption; that is: in actual operation, the user can attach the corresponding gas pipe to the breathable net, and then connect the circulating fan body to the power supply, then the circulating fan body will guide and absorb the airflow, so that the airflow is drawn in from the breathable net, and the breathable net plays a certain filtering role on the airflow, then After entering the ventilation frame, the airflow passes through the burner body, facilitating ignition. The hot air then impacts the guide plate, which is then diverted and guided by the V-shaped guide plate. Next, the hot airflow contacts the vertical plate, where multiple corrugated pipes further distribute the airflow more evenly into the combustion chamber. The airflow then passes through the suction hood and filter before entering the circulating fan body, further diverting and guiding the hot air for combustion. This ensures uniform temperature distribution throughout the combustion chamber, preventing excessively high temperatures on fabrics and reducing yellowing. The multiple corrugated pipes also ensure more complete combustion, improving the heat dissipation efficiency of the heat sink assembly and reducing gas consumption.

[0013] (2) The indirect combustion system of the setting machine described in this invention, when in use, the flattening mechanism is set on the transmission mechanism. Through the flattening mechanism, it is convenient to flatten the edge of the conveyed fabric during operation, so as to avoid the fabric from wrinkling due to various external factors, thus ensuring the drying effect of the fabric and improving the stability of the entire processing process; that is, in actual operation, the user can grasp and rotate the handwheel in advance, and the rotation of the handwheel will drive the screw to rotate together. As the screw rotates, it will drive the moving block to move continuously inside the fixed block. The moving block moves and then drives the flattening roller on it to move together until the flattening roller touches the surface of the conveyed fabric, thus making it convenient to flatten the edge of the conveyed fabric during operation, so as to avoid the fabric from wrinkling due to various external factors, thus ensuring the drying effect of the fabric and improving the stability of the entire processing process.

[0014] (3) The indirect combustion system of the setting machine described in this invention, when in use, the heating mechanism is set inside the oven. Through the heating mechanism, the hot air blown to the fabric surface is further differentiated and guided, reducing the generation of overheated airflow, thereby further reducing the damage to the fabric surface and avoiding the yellowing of the fabric; that is, after the hot airflow enters the body of the circulating fan, it will then enter the body of the spray box through the pipe joint, and then be sprayed out through multiple nozzles to dry the fabric, thereby further differentiating and guiding the hot air blown to the fabric surface, reducing the generation of overheated airflow, thereby further reducing the damage to the fabric surface and avoiding the yellowing of the fabric.

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0025] like Figures 1-7 As shown, the indirect combustion system of the stenter of the present invention includes a placement oven 1, a transmission mechanism 2 on the placement oven 1, a flattening mechanism 3 on the transmission mechanism 2, a suction mechanism 4 on the placement oven 1, a burner body 5 and a flow diversion mechanism 6 inside the suction mechanism 4, and a heating mechanism 7 inside the placement oven 1.

[0026] The suction mechanism 4 includes a mounting frame 401, a ventilation frame 402 fixedly connected to one side of the mounting frame 401, a ventilation net 403 provided on the ventilation frame 402, a circulating fan body 404 provided inside the mounting frame 401, a filter screen 405 installed inside the mounting oven 1, and the filter screen 405 is located on one side of the opening of the circulating fan body 404. A suction hood 406 is provided on the side wall of the ventilation frame 402 near the mounting frame 401, and the cross-section of the suction hood 406 is funnel-shaped.

[0027] The diversion mechanism 6 includes a guide plate 601, which is fixedly connected inside the vent frame 402. The guide plate 601 has a V-shaped cross-section. A vertical plate 602 is fixedly connected inside the mounting frame 401. A mesh 603 is provided on the vertical plate 602. Multiple corrugated pipes 604 are fixedly connected to the vertical plate 602. The guide plate 601 has multiple through holes arranged in a rectangular array. The corrugated pipes 604 are arranged in two groups of multiple pipes, with each group of multiple corrugated pipes 604 arranged in an equilateral triangle. In use... The suction mechanism 4 is mounted on the oven 1, and the diversion mechanism 6 is located inside the suction mechanism 4. Through the cooperation of the suction mechanism 4 and the diversion mechanism 6, the hot air for combustion heating is easily diverted and guided, ensuring uniform temperature distribution throughout the combustion chamber, preventing excessively high temperatures on the fabric, reducing yellowing of the fabric surface, and also allowing for more complete combustion, improving the heat dissipation efficiency of the heat dissipation pipe assembly, and reducing gas consumption. In actual operation, the user can attach the corresponding gas pipe to the breathable mesh 403, and then... When the circulating fan body 404 is powered on, it guides and absorbs the airflow, drawing it in through the vent mesh 403. The vent mesh 403 filters the airflow. After entering the vent frame 402, the airflow passes through the burner body 5 for ignition. The hot airflow then impacts the guide plate 601, which is V-shaped and diverts the flow. Finally, the hot airflow contacts the vertical plate 602. The multiple corrugated pipes 604 installed on the vertical plate 602 further ensure a more uniform distribution of airflow into the combustion chamber. The airflow then passes through the suction hood 406 and the filter screen 405 and enters the circulating fan body 404, thus facilitating the diversion and guidance of the hot air for combustion heating. This ensures uniform temperature distribution throughout the combustion chamber, prevents excessively high temperatures from blowing onto the fabric, and reduces yellowing of the fabric surface. At the same time, the multiple corrugated pipes 604 also ensure more complete combustion, improve the heat dissipation efficiency of the heat dissipation pipe assembly, and reduce gas consumption.

[0028] Specifically, the transmission mechanism 2 includes a support 201. A support 201 is fixedly connected to each side of the oven 1, and a transmission belt body 203 is provided between the two supports 201. Support legs 202 are fixedly connected to the support 201, and the support legs 202 are generally L-shaped. In use, the support 201 and support legs 202 are used to support and fix the entire device. In actual operation, the transmission belt body 203 is used to facilitate the transportation of the corresponding fabrics.

[0029] Specifically, the flattening mechanism 3 includes a fixed block 301, which is fixedly connected to the top of one side of the support 201. A handwheel 302 is provided on the fixed block 301, and a lead screw 303 is fixedly connected to the handwheel 302. The lead screw 303 is rotatably connected inside the fixed block 301. A moving block 304 is slidably connected inside the fixed block 301. The lead screw 303 and the moving block 304 are threaded together. A flattening roller 305 is rotatably connected to the moving block 304. A baffle 306 is fixedly connected to the top of one side of the fixed block 301, and one end of the baffle 306 is arc-shaped. In use, the flattening mechanism 3 is mounted on the conveying mechanism 2, allowing for the smoothing of the edges of the conveyed fabric during operation. To prevent wrinkles in the fabric due to various external factors, ensuring the subsequent drying effect and improving the stability of the entire processing, the user can grip and rotate the handwheel 302 beforehand. The rotation of the handwheel 302 drives the lead screw 303 to rotate as well. As the lead screw 303 rotates, it drives the moving block 304 to move continuously inside the fixed block 301. The movement of the moving block 304 then drives the flattening roller 305 on it to move together until the flattening roller 305 comes into contact with the surface of the conveyed fabric. This facilitates the smoothing of the edges of the conveyed fabric during operation, preventing wrinkles caused by various external factors, ensuring the subsequent drying effect and improving the stability of the entire processing.

[0030] Specifically, the heating mechanism 7 includes a mounting block 701, which is fixedly connected inside the mounting oven 1. A spray box body 702 is installed inside the mounting block 701. Multiple nozzle bodies 703 are provided on the spray box body 702, extending into the inner cavity of the mounting oven 1. A pipe connector 704 is fixedly connected to the spray box body 702, and the air outlet of the circulating fan body 404 is connected to the pipe connector 704. In use, the heating mechanism 7 is placed inside the mounting oven 1, and through the heating mechanism 7, thereby... The hot air blown onto the fabric surface is further differentiated and guided, reducing the generation of overheated airflow, which further reduces damage to the fabric surface and prevents the fabric from yellowing. Specifically, after the hot airflow enters the interior of the circulating fan body 404, it will then enter the interior of the spray box body 702 through the pipe joint 704, and then be sprayed out through multiple nozzle bodies 703 to dry the fabric. This further differentiates and guides the hot air blown onto the fabric surface, reducing the generation of overheated airflow, which further reduces damage to the fabric surface and prevents the fabric from yellowing.

[0031] In use, the present invention firstly uses the bracket 201 and support legs 202 to facilitate the support and fixation of the entire device. During actual operation, the conveyor belt body 203 facilitates the transportation of the corresponding fabric. In actual operation, the user can grasp and rotate the handwheel 302 beforehand. The rotation of the handwheel 302 drives the lead screw 303 to rotate together. As the lead screw 303 rotates, it drives the moving block 304 to move continuously inside the fixed block 301. The movement of the moving block 304 then drives the flattening roller 305 on it to move together until the flattening roller 305 comes into contact with the conveyed fabric. The surface is smoothed to facilitate the flattening of the edges of the conveyed fabric during operation, preventing wrinkles caused by various external factors, thus ensuring the subsequent drying effect and improving the stability of the entire processing. Next, during operation, the user attaches the corresponding gas pipe to the breathable mesh 403, then connects the circulating fan body 404 to the power supply. The circulating fan body 404 then guides and absorbs the airflow, drawing it in through the breathable mesh 403. The breathable mesh 403 filters the airflow. After entering the ventilation frame 402, the airflow passes through... The burner body 5 facilitates the ignition of the airflow. Subsequently, this hot airflow impacts the guide plate 601, which is then diverted and guided by the V-shaped guide plate 601. Next, this hot airflow contacts the vertical plate 602, where multiple corrugated pipes 604 further ensure a more uniform distribution of the airflow entering the combustion chamber. The airflow then passes through the suction hood 406 and filter 405 before entering the circulating fan body 404. This facilitates the diversion and guidance of the hot air for combustion heating, ensuring uniform temperature distribution throughout the combustion chamber and preventing drafting. To prevent the fabric from overheating and yellowing, the multiple corrugated pipes 604 ensure more complete combustion, improve the heat dissipation efficiency of the heat dissipation pipe assembly, and reduce gas consumption. Furthermore, after the hot airflow enters the circulating fan body 404, it enters the spray box body 702 through the pipe joint 704, and is then sprayed out through multiple nozzle bodies 703 to dry the fabric. This further disperses and guides the hot air blowing onto the fabric surface, reducing the generation of overheated airflow and further reducing damage to the fabric surface, thus preventing the fabric from yellowing.
