Description

Technical Field

[0001] This utility model relates to the technical field of tenter frame accessories, specifically a slurry baffle adjustment device for tenter frame. Background Technology

[0002] Tentator sets are key pieces of equipment in the textile industry used for fabric finishing. Their main function is to mechanically stretch and heat-set fabrics to achieve predetermined width, shape, and stability, while also performing finishing processes such as softening, stiffening, and anti-slip treatments. Their core structure includes a fabric feeding device, guide rollers, an oven, and a cooling zone, and they are widely used in processing various fabrics such as cotton, synthetic fibers, and blends. When fabric is tensioned and conveyed through the guide rollers, especially during padding, sizing, or dyeing processes, sizing agents or liquids may splash. Sizing baffles physically confine the splashed liquid to a specific area, preventing contamination of other parts or fabrics. Some sizing baffles feature a height-adjustable or movable design, allowing the height to be adjusted according to the fabric conveying position and the degree of splashing.

[0003] A slurry baffle adjustment device for a tenter frame, application number 201610018755.3, includes a motor assembly and a transmission assembly. The motor assembly includes a motor, a coupling, and a drive shaft, all horizontally arranged. Two sets of transmission assemblies are installed at the middle and end positions of the drive shaft, respectively. Each set has two upper fixing blocks and one lower fixing block. The two upper fixing blocks are fixedly connected to the guide frame of the tenter frame, and the lower fixing block is connected to a connecting plate. The connecting plate is horizontal, and a slurry baffle is installed below it. This invention modifies the current design of the slurry baffle in tenter frames, which is screwed to the guide frame, allowing the slurry baffle to automatically rise or fall for easier cleaning.

[0004] This technical solution uses an electric actuator to drive a rotating shaft, which in turn drives a slurry baffle to move up and down via a linkage mechanism, thereby adjusting the height of the slurry baffle. However, this solution has several drawbacks. First, it is energy-intensive. After adjustment, the motor needs to be continuously powered to ensure the limit switch is engaged. If the motor is turned off or there is a power outage, the lack of a limit switch will cause the slurry baffle to easily move downwards due to gravity. The impact of this downward movement can easily damage the linkage and guide structures. Second, the structure is open, and slurry may splash onto the top of the slurry baffle, increasing the resistance to structural movement and aggravating structural wear. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a slurry baffle adjustment device for a tenter frame to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a slurry baffle adjustment device for a tenter frame, comprising a mounting frame and a baffle body. A servo motor is installed on one side inside the mounting frame, and a worm gear reducer is connected to the output end of the servo motor. A lead screw is connected to the output end of the worm gear reducer, and a first slide is connected to the top of the lead screw. A second slide is connected inside the baffle body, and connecting rods are connected between the first slide and the second slide, and between the mounting frame and the baffle body. An electromagnetic brake is installed at the lower part inside the mounting frame. A first baffle is connected to the outer surface of the mounting frame, and a second baffle is connected to the outer surface of the baffle body. Both the outer surfaces of the first baffle and the second baffle are connected to flexible baffles via fixed edge strips.

[0007] By adopting the above technical solution, the operator installs the mounting bracket into the tenter frame using bolts. When the height of the baffle body needs to be adjusted, the operator starts the servo motor. After the servo motor starts, its output drives the lead screw to rotate through the worm gear reducer. After the lead screw rotates, the position of the first slide is adjusted. At the same time, the first and second guide rails guide and prevent the first slide from rotating. The first slide, the second slide, the connecting rod, and the rotating shaft form a scissor lifting mechanism, thereby adjusting the height of the baffle body. Through the precise control of the servo motor and the increased control resolution of the worm gear reducer, compared with the technical solution mentioned in the background art, the height of the baffle body can be adjusted with higher precision. Furthermore, the worm gear reducer, in conjunction with the rotation of the lead screw, forms... The structure is self-locking, effectively preventing the baffle body from falling due to gravity when power is off and causing safety accidents. The electromagnetic brake automatically brakes when power is off, further improving the stability of the baffle body's height limit. Moreover, it does not require continuous power supply to the electromagnetic brake, making it energy-saving and environmentally friendly. The transmission structure inside the mounting frame is shielded by the first baffle, and the movable structure on the baffle body is shielded by the second baffle. In addition, to prevent splashed slurry from passing through due to changes in the gap between the mounting frame and the baffle body, the flexible baffle blocks this gap. The flexible baffle deforms itself during the lifting and lowering of the baffle body, dynamically compensating for the gap, effectively preventing slurry from splashing and adhering to the structure, increasing the structural running resistance.

[0008] Furthermore, a first guide rail is connected to the lower interior of the mounting bracket, and a second guide rail is connected to the back of the mounting bracket.

[0009] By adopting the above technical solution, the bottom of the first slide is supported by the first guide rail, and the upper back of the first slide is supported by the second guide rail, so that the first slide can be stably moved laterally inside the mounting frame.

[0010] Furthermore, the first slide is threadedly connected to the lead screw, and the first slide is slidably connected to the first guide rail and the second guide rail respectively.

[0011] By adopting the above technical solution, after the servo motor starts, the output end drives the lead screw to rotate through the worm gear reducer. After the lead screw rotates, the position of the first slide is adjusted. At the same time, the first guide rail and the second guide rail guide and prevent the first slide from rotating.

[0012] Furthermore, the second slide block is slidably connected to the baffle body, and the two ends of the two connecting rods are respectively rotatably connected to the first slide block, the second slide block, the mounting bracket, and the baffle body.

[0013] By adopting the above technical solution, the lead screw drives the first slide to move, which in turn drives one of the connecting rods to move. The rotation of the two connecting rods causes the second slide to move synchronously, and the rotation of the two connecting rods causes the baffle body to move up or down.

[0014] Furthermore, a pivot is connected between the two links, and one link is rotatably connected to the other link via the pivot.

[0015] By adopting the above technical solution, when the first sliding seat moves, it causes one end of one of the connecting rods to move. At this time, the rotation area between the two connecting rods is subjected to force, causing the two ends of the two connecting rods and the two connecting rods to rotate.

[0016] Furthermore, one end of the lead screw is connected to an electromagnetic brake.

[0017] By adopting the above technical solution, the electromagnetic brake automatically brakes when power is cut off, which can further improve the stability of the height limit of the baffle body.

[0018] Furthermore, the flexible baffle is fixedly connected to the edge strip by a silicone rubber adhesive.

[0019] By adopting the above technical solution, the two narrower sides of the flexible baffle are glued to the surface of the fixing strip using silicone rubber adhesive, thereby reinforcing the two narrower sides of the flexible baffle and preventing deformation of these two sides from affecting the connection stability.

[0020] Furthermore, the flexible baffle and the fixed edge strip are detachably connected to the first baffle and the second baffle respectively by bolts.

[0021] By adopting the above technical solution, when the flexible barrier is damaged or torn, the flexible barrier and the fixed edge strip can be disassembled and replaced by bolts, which is convenient for maintenance and provides a stable connection.

[0022] Furthermore, the main body of the baffle, the connecting rod, the second baffle and the fixed edge strip are all made of 6061-T6 aluminum alloy.

[0023] By adopting the above technical solutions, the structure below the connecting rod is mostly made of 6061-T6 aluminum alloy. Firstly, it has good corrosion resistance, secondly, it is lighter than other metals such as stainless steel, and it is also strong enough to reduce load and energy consumption.

[0024] Furthermore, the flexible baffle has a sandwich structure, with the inner core being nylon 66 fiber cloth and the outer layer being silicone rubber. The inner core and outer layer of the flexible baffle are fixed together by a vulcanization process.

[0025] By adopting the above technical solution, the surface layer of the flexible baffle is made of silicone rubber, and the main body of the flexible baffle is also made of silicone rubber. It has good flexibility and fatigue resistance and can be deformed to achieve the purpose required by this technical solution. The inner core is made of nylon fiber cloth to reinforce the silicone rubber, thereby improving the tear resistance and load-bearing capacity of the flexible baffle. Moreover, the nylon 66 fiber cloth is resistant to temperatures above 200 degrees Celsius, while the vulcanization temperature of silicone rubber is usually between 150 and 200 degrees Celsius. This facilitates the vulcanization and fixation of the nylon 66 fiber cloth and the silicone rubber without causing the fiber cloth to burn or its performance to be significantly affected.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model utilizes a servo motor, worm gear reducer, lead screw, and electromagnetic brake. The servo motor provides precise control, while the worm gear reducer increases control resolution, enabling more accurate adjustment of the baffle body height. Furthermore, the worm gear reducer, in conjunction with the lead screw, creates a self-locking structure, effectively preventing the baffle body from falling due to gravity during power outages and causing safety accidents. The electromagnetic brake automatically brakes upon power failure, further improving the stability of the baffle body height limit. Moreover, it eliminates the need for continuous power to the electromagnetic brake, resulting in energy saving and environmental protection, and enhancing safety.

[0028] 2. By setting up a first baffle and a second baffle, the first baffle blocks the transmission structure inside the mounting frame, and the second baffle blocks the movable structure on the baffle body, effectively preventing the phenomenon of slurry splashing and adhering to the structure, thus increasing the structural running resistance; reducing the phenomenon of slurry splashing increasing resistance.

[0029] 3. By setting up a fixed edge strip and a flexible baffle, this utility model avoids the phenomenon that splashed slurry can pass through due to changes in the gap between the mounting frame and the baffle body. The flexible baffle blocks this gap, and the flexible baffle deforms itself during the lifting and lowering of the baffle body to dynamically compensate for the gap, thereby effectively preventing slurry from passing through and increasing the blocking effect.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1:

[0039] A slurry baffle adjustment device for a tenter frame, such as Figures 1-5 As shown, the device includes a mounting frame 1 and a baffle body 2. A first guide rail 6 is connected to the lower part of the mounting frame 1, and a second guide rail 7 is connected to the back of the mounting frame 1. A servo motor 3 is installed on one side of the mounting frame 1. A worm gear reducer 4 is connected to the output end of the servo motor 3, and a lead screw 5 is connected to the output end of the worm gear reducer 4. An electromagnetic brake 12 is installed at the lower part of the mounting frame 1. One end of the lead screw 5 is connected to the electromagnetic brake 12. Through the precise control of the servo motor 3 and the increased control resolution of the worm gear reducer 4, the height of the baffle body 2 can be adjusted with higher precision. The worm gear reducer 4 rotates in conjunction with the lead screw 5 to form a self-locking structure, effectively preventing the baffle body 2 from falling due to gravity when the power is off and causing a safety accident. The electromagnetic brake 12 automatically brakes when the power is off, which can further improve the stability of the height limit of the baffle body 2. Moreover, the electromagnetic brake 12 does not need to be continuously powered to maintain the height, which is energy-saving and environmentally friendly.

[0040] A first baffle 13 is connected to the outer surface of the mounting frame 1, and a second baffle 14 is connected to the outer surface of the baffle body 2. Both the outer surfaces of the first baffle 13 and the second baffle 14 are connected to flexible baffles 16 via fixed edge strips 15. The flexible baffles 16 and the fixed edge strips 15 are detachably connected to the first baffle 13 and the second baffle 14 respectively by bolts. The flexible baffles 16 are fixedly connected to the fixed edge strips 15 by silicone rubber adhesive. The first baffle 13 shields the transmission structure inside the mounting frame 1, and the second baffle 14 shields the movable structure on the baffle body 2. In order to prevent the phenomenon that splashed slurry can pass through due to the change in the gap between the mounting frame 1 and the baffle body 2, the flexible baffles 16 shield this gap. Moreover, the flexible baffles 16 deforms itself during the lifting and lowering of the baffle body 2, dynamically compensating for the gap, effectively preventing the phenomenon that splashed slurry adheres to the structure and increases the structural running resistance.

[0041] See Figures 1-4 In the above embodiment, a first slide block 8 is connected to the top of the lead screw 5. The first slide block 8 is threadedly connected to the lead screw 5. The first slide block 8 is slidably connected to the first guide rail 6 and the second guide rail 7 respectively. A second slide block 9 is connected inside the baffle body 2. The second slide block 9 is slidably connected to the baffle body 2. A connecting rod 10 is connected between the first slide block 8 and the second slide block 9 and between the mounting bracket 1 and the baffle body 2. The two ends of the two connecting rods 10 are rotatably connected to the first slide block 8, the second slide block 9, the mounting bracket 1 and the baffle body 2 respectively. A rotating shaft 11 is connected between the two connecting rods 10. One connecting rod 10 is rotatably connected to the other connecting rod 10 through the rotating shaft 11. The first slide block 8, the second slide block 9, the connecting rod 10 and the rotating shaft 11 form a scissor lifting mechanism, thereby changing and adjusting the height of the baffle body 2.

[0042] Example 2:

[0043] Based on the above embodiment one, to increase structural stability, the following settings are now implemented.

[0044] See Figures 1-5 In the above embodiments, the baffle body 2, the connecting rod 10, the second baffle 14 and the fixed edge strip 15 are all made of 6061-T6 aluminum alloy. The structure below the connecting rod 10 is mostly made of 6061-T6 aluminum alloy, which has good corrosion resistance, is lighter than other metals such as stainless steel, and has high strength, thus reducing load and energy consumption.

[0045] Example 3:

[0046] Based on the above embodiment 1, in order to increase the strength of the flexible baffle 16, the following settings are now adopted.

[0047] See Figure 1 and Figure 5In the above embodiments, the flexible baffle 16 is a sandwich structure. The inner core of the flexible baffle 16 is nylon 66 fiber cloth, and the outer layer of the flexible baffle 16 is silicone rubber. The main body of the flexible baffle 16 is silicone rubber, which has good flexibility and fatigue resistance and can be deformed to achieve the purpose required by this technical solution. The inner core is made of nylon fiber cloth to reinforce the silicone rubber, thereby improving the tear resistance and load-bearing capacity of the flexible baffle. The inner core and the outer layer of the flexible baffle 16 are fixed by a vulcanization process. The nylon 66 fiber cloth is resistant to temperatures above 200 degrees Celsius, while the vulcanization temperature of silicone rubber is usually between 150 and 200 degrees Celsius. This facilitates the vulcanization and fixation of the nylon 66 fiber cloth and the silicone rubber without causing the fiber cloth to burn or its performance to be greatly affected.

[0048] The implementation principle of this utility model is as follows: First, the operator installs the mounting bracket 1 into the tenter frame using bolts. When it is necessary to adjust the height of the baffle body 2, the operator turns on the servo motor 3. After the servo motor 3 starts, its output end drives the lead screw 5 to rotate through the worm gear reducer 4. After the lead screw 5 rotates, it adjusts the position of the first slide block 8. At the same time, the first guide rail 6 and the second guide rail 7 guide and prevent the first slide block 8 from rotating. The first slide block 8, the second slide block 9, the connecting rod 10, and the rotating shaft 11 form a scissor lifting mechanism, thereby adjusting the height of the baffle body 2. Through the precise control of the servo motor 3 and the increased control resolution of the worm gear reducer 4, the height of the baffle body 2 can be adjusted with higher precision compared to the technical solutions mentioned in the background art. Moreover, the worm gear reducer 4, in conjunction with the rotation of the lead screw 5, forms a self-locking structure, effectively preventing the baffle body 2 from falling due to gravity when the power is off, thus avoiding safety accidents. Furthermore, the electromagnetic brake 12 automatically brakes when the power is off, which can further improve the stability of the height limit of the baffle body 2. Moreover, the electromagnetic brake 12 does not need to be continuously powered on, which is energy-saving and environmentally friendly.

[0049] The transmission structure inside the mounting frame 1 is blocked by the first baffle 13, and the movable structure on the baffle body 2 is blocked by the second baffle 14. In order to prevent the phenomenon that splashed slurry can pass through due to the change in the gap between the mounting frame 1 and the baffle body 2, the flexible baffle 16 blocks this gap. The flexible baffle 16 deforms itself during the lifting and lowering of the baffle body 2 to dynamically compensate for the gap, effectively preventing the phenomenon that splashed slurry adheres to the structure and increases the structural running resistance.
