TECHNICAL FIELD
[0001] The utility model relates to the technical field of fabric processing, in particular to a sofa fabric leveling mechanism. BACKGROUND
[0002] Sofa fabric refers to the textile material used to cover the surface of the sofa, which is an important part of the sofa, not only affects the appearance and comfort of the sofa, but also determines its durability, easy cleaning and environmental protection, with the improvement of people's living standards and the increase of home decoration demand, the types and performance of sofa fabric are also constantly enriched and improved.
[0003] At present, the sofa fabric on the market mainly has two kinds, one is leather fabric, and the other is knitted fabric, wherein the rough leveling process of knitted fabric is: feeding, guiding the knitted fabric from the feeding roller into the leveling device; hot steam treatment, the fabric passes through the hot steam box, and the steam softens the fabric; straightening and leveling, the fabric is preliminarily straightened and leveled; ironing treatment, the fabric passes through the ironing plate for ironing, and is further leveled; cooling, the leveled fabric is cooled by the fan to avoid affecting the subsequent treatment due to the high temperature of the fabric.
[0004] The knitted fabric on the market currently needs to be preliminarily straightened and leveled before ironing leveling in the leveling process, and this process is easy to cause excessive stretching of the knitted fabric, thereby causing damage to the knitted fabric, and omitting this process will cause wrinkles in the subsequent ironing process, thereby affecting the final product quality of the fabric, therefore, a leveling mechanism without damaging the fabric is designed. UTILITY MODEL CONTENT
[0005] Therefore, the utility model aims at providing a sofa fabric leveling mechanism to solve the technical problem that the traditional device may damage the fabric in the leveling process.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a sofa fabric smoothing mechanism, comprising a main body, two first rotating shafts connected between the two sides of the main body, and rollers sleeved on the outer sides of both first rotating shafts. Each roller is connected to a corresponding first rotating shaft with a first spiral spring, and the two rollers cooperate with each other. Two second rotating shafts are rotatably connected between the two sides of the main body behind the first rotating shafts, and the sides of the two second rotating shafts that are close to each other are connected to mutually cooperating detection blocks. Each of the two second rotating shafts is connected to a clamping block that cooperates with the corresponding detection block, and the two clamping blocks cooperate with each other. Two second rotating shafts are rotatably connected between the two sides of the main body behind the second rotating shafts. The main body has a third rotating shaft, and a rotating motor is installed inside the main body. The output end of the rotating motor is connected to two third rotating shafts respectively. A second spiral spring is connected to each of the two third rotating shafts. A traction wheel is sleeved on the outside of each of the two third rotating shafts, and a locking block is fixed inside each traction wheel. The outer ends of the two second spiral springs are engaged with the corresponding locking blocks. Each roller and traction wheel is engaged with the fabric, and the friction between the traction wheel and the fabric is greater than the friction between the roller and the fabric. Both detection blocks are in sliding contact with the fabric, and both clamping blocks are engaged with the fabric. A stop block is provided below the lower clamping block to engage with it, and a counterweight block is installed on the upper roller to engage with it.
[0007] By adopting the above technical solution, the fabric passes through the roller, then sequentially through the detection block and the traction wheel. Because the friction between the traction wheel and the fabric is greater than that between the roller and the fabric, the first rotating shaft cannot rotate. Therefore, during the rotation of the traction wheel, the roller rotates under the deformation of the corresponding first spiral spring. During this period, some wrinkles are generated on the fabric. When the wrinkles pass the detection block, they push the detection block to rotate backward along the second rotating shaft, thereby causing the clamping block to rotate inward and contact the fabric. This further causes the clamping block to continue rotating inward, thus completing the clamping of the fabric. At this time, the traction wheel continues to rotate, thus completing the stretching and flattening of the fabric. When the third rotating shaft continues to rotate and generates a certain torque, the second spiral spring deforms and disengages from the corresponding clamping block. At this time, the traction wheel contacts the restraint and stops traction on the fabric until the outer end of the second spiral spring contacts the clamping block again. During this second contact, the first spiral spring resets, pulling the fabric back through the roller, thereby releasing the clamping block. At this time, the traction wheel, which rotates again, pulls the fabric to move once more.
[0008] The present invention is further configured such that the outer periphery of the two second spiral springs is connected to an inner wheel that slides in contact with the corresponding locking block.
[0009] By adopting the above technical solution, the inner wheel is used to regulate the relative position of the traction wheel.
[0010] The present invention is further configured such that a steam jet assembly is installed inside the main body in front of the first rotating shaft, and the output end of the steam jet assembly is connected to a steam nozzle, which is in conjunction with the fabric.
[0011] By adopting the above technical solution, the steam ejected from the steam nozzle softens the fabric and increases the toughness of the fabric surface, preventing damage to the fabric during the subsequent leveling process.
[0012] The present invention is further configured such that an ironing device that cooperates with the fabric is installed inside the main body behind the third rotating shaft.
[0013] By adopting the above technical solution, the flattened fabric is finally shaped by an ironing device.
[0014] The present invention is further configured such that a soft brush, which is compatible with the fabric, is installed inside the main body in front of the steam nozzle.
[0015] By adopting the above technical solution, a soft brush is used to clean dust and debris from the surface of fabric.
[0016] The present invention is further configured such that a dust collection device is installed inside the main body, and the suction end of the dust collection device is located at the soft brush.
[0017] By adopting the above technical solution, the dust collection device is used to collect flying dust and prevent the dust from falling back onto the fabric.
[0018] The present invention is further configured such that traction conveyor belts penetrating both ends of the main body are installed on both sides of the interior of the main body, and the traction conveyor belts cooperate with the fabric.
[0019] By adopting the above technical solution, the traction conveyor belt is used to guide the fabric through the soft brush, steam nozzle, roller, detection block, traction wheel and ironing device in sequence.
[0020] In summary, the present invention has the following main advantages:
[0021] This invention uses a detection block to identify wrinkled areas on the fabric surface, and then uses a clamping block and a traction wheel to flatten the wrinkled areas. Then, the second spiral spring disengages from the corresponding locking block, thereby releasing the restriction between the clamping block and the traction wheel, so as to avoid affecting the subsequent flattening of the fabric and preventing excessive stretching and damage to the fabric.

Detailed Implementation
[0027] 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.
[0028] The embodiments of this utility model will be described below based on its overall structure.
[0029] A sofa fabric leveling mechanism, such as Figures 1-4As shown, the device includes a main body 1. Two first rotating shafts 6 are connected between the two sides of the main body 1. Rollers 8 are fitted onto the outer sides of both first rotating shafts 6. Each roller 8 is connected to a corresponding first rotating shaft 6 via a first spiral spring 7. The two rollers 8 cooperate with each other. Two second rotating shafts 9 are rotatably connected between the two sides of the main body 1, located behind the first rotating shafts 6. Detection blocks 10 are connected to the sides of the two second rotating shafts 9 that are close to each other. Clamping blocks 11 are connected to the two second rotating shafts 9, cooperating with the corresponding detection blocks 10. The clamping blocks 11 cooperate with each other. Two third rotating shafts 15 are rotatably connected to the rear of the main body 1. A rotating motor is installed inside the main body 1, and the output end of the rotating motor is connected to the two third rotating shafts 15 respectively. A second spiral spring 14 is connected to each of the two third rotating shafts 15. A traction wheel 12 is sleeved on the outside of each of the two third rotating shafts 15, and a locking block 13 is fixed inside each traction wheel 12. The outer ends of the two second spiral springs 14 are engaged with the corresponding locking blocks 13. Each roller 8 and traction wheel 12 is engaged with the fabric, and the friction between the traction wheel 12 and the fabric is greater than the friction between the roller 8 and the fabric. Both detection blocks 10 are in sliding contact with the fabric, and both clamping blocks 1... All components are designed to work with the fabric. A stop block is positioned below the lower clamping block 11, and a counterweight is mounted on the upper roller 8. After passing through the roller 8, the fabric passes sequentially through the detection block 10 and the traction wheel 12. Because the friction between the traction wheel 12 and the fabric is greater than that between the roller 8 and the fabric, the first rotating shaft 6 cannot rotate. Therefore, during the rotation of the traction wheel 12, the roller 8 rotates under the deformation of the corresponding first spiral spring 7. During this period, some wrinkles are formed on the fabric. When the wrinkles pass through the detection block 10, they push the detection block 10 to rotate backward along the second rotating shaft 9, thereby driving the clamping block. The clamping block 11 rotates inward to make contact with the fabric, thereby driving the clamping block 11 to continue rotating inward to complete the clamping of the fabric. At this time, the traction wheel 12 continues to rotate to complete the stretching and flattening of the fabric. When the third rotating shaft 15 continues to rotate and generates a certain torque, the second spiral spring 14 deforms and disengages from the corresponding locking block 13. At this time, the traction wheel 12 contacts the restraint and stops traction on the fabric until the outer end of the second spiral spring 14 contacts the locking block 13 again. During this period, the first spiral spring 7 resets and pulls the fabric back through the roller 8, thereby releasing the clamping of the clamping block 11. At this time, the traction wheel 12, which rotates again, pulls the fabric to move again.
[0030] The outer periphery of the two second spiral springs 14 is connected to an inner wheel 16 that slides in contact with the corresponding locking block 13. The inner wheel 16 is used to regulate the relative position of the traction wheel 12.
[0031] Inside the main body 1, in front of the steam nozzle 5, there is a soft brush 3 that matches the fabric. The soft brush 3 is used to clean dust and debris from the surface of the fabric.
[0032] The main body 1 is equipped with a dust collection device 4, and the suction end of the dust collection device 4 is located at the soft brush 3. The dust collection device 4 is used to collect flying dust and prevent dust from falling back onto the fabric.
[0033] Inside the main body 1, in front of the first rotating shaft 6, a steam jet assembly is installed, and the output end of the steam jet assembly is connected to a steam nozzle 5. The steam nozzle 5 is in conjunction with the fabric, and the steam jetted from the steam nozzle 5 softens the fabric and increases the toughness of the fabric surface, preventing damage to the fabric during the subsequent leveling process.
[0034] Inside the main body 1, behind the third rotating shaft 15, is an ironing device 17 that works with the fabric. The flattened fabric is then ironed by the ironing device 17 to achieve its final shaping.
[0035] Both sides of the interior of the main body 1 are equipped with traction conveyor belts 2 that run through both ends of the main body 1. The traction conveyor belts 2 cooperate with the fabric and are used to guide the fabric to pass through the soft brush 3, steam nozzle 5, roller 8, detection block 10, traction wheel 12 and ironing device 17 in sequence.
[0036] Working principle: The traction conveyor belt 2 guides the fabric sequentially through the soft brush 3, steam nozzle 5, roller 8, detection block 10, traction wheel 12, and ironing device 17. The soft brush 3 cleans dust and debris from the fabric surface, while the dust collection device 4 collects airborne dust to prevent it from falling back onto the fabric. The cleaned surface then passes through the steam nozzle 5. The steam from the nozzle softens the fabric and increases its surface toughness, preventing damage during subsequent leveling. The fabric then passes through roller 8, detection block 10, and traction wheel 12. Because the friction between the traction wheel 12 and the fabric is greater than that between the roller 8 and the fabric, the first rotating shaft 6 cannot rotate. Therefore, as the traction wheel 12 rotates, the roller 8 rotates under the deformation of the corresponding first spiral spring 7. During this process, some wrinkles are created on the fabric. When the fabric passes the detection block 10, it pushes the detection block 10 to rotate backward along the second rotating shaft 9, thereby causing the clamping block 11 to rotate inward and come into contact with the fabric. This causes the clamping block 11 to continue rotating inward, thus clamping the fabric. At this time, the traction wheel 12 continues to rotate, thereby stretching and flattening the fabric. When the third rotating shaft 15 continues to rotate and generates a certain torque, the second spiral spring 14 deforms and disengages from the corresponding locking block 13. At this time, the traction wheel 12 contacts the restraint and stops traction on the fabric until the outer end of the second spiral spring 14 contacts the locking block 13 again. During this period, the first spiral spring 7 resets and pulls the fabric back through the roller 8, thereby releasing the clamping block 11. At this time, the traction wheel 12 rotates again and pulls the fabric to move. Finally, the flattened fabric passes through the ironing device 17 under the traction of the traction wheel 12 to complete the final shaping of the fabric.
