Description

Technical Field

[0001] This utility model relates to the field of textile machinery and equipment technology, and in particular to a cloth grading machine length adjustment device. Background Technology

[0002] As a key piece of equipment in textile processing for neatly stacking fabric, the core function of a fabric stacking machine is to arrange fabric in an orderly manner according to specific length requirements, facilitating subsequent production processes such as cutting and sewing. With the continuous upgrading of the textile industry's demand for automated and refined production, the performance of fabric stacking machines directly affects production efficiency and product quality. In particular, the functionality and reliability of the length adjustment device have become important factors restricting production levels.

[0003] Currently, fabric stacking machines on the market face numerous problems in practical applications that urgently need to be addressed. Regarding fabric securing, traditional fabric stacking machines have a relatively simple pressing structure design, unable to flexibly adjust the pressing force and position according to the actual needs after adjusting the fabric length. After the stacking machine completes the length adjustment, due to the lack of an effective pressing and limiting mechanism, the fabric is prone to slippage and displacement during continuous stacking, leading to problems such as wrinkles and uneven stacking, making it difficult to achieve stable and efficient continuous stacking operations.

[0004] Regarding the accuracy of length adjustment, a length adjustment device for a fabric stacking machine is proposed, referring to the existing authorized patent CN 222159313 U. This device uses a motor to drive a guide frame to move left and right to stack the fabric. Its structure is simple, and by controlling the forward and reverse rotation of the motor, the left and right movement of the guide frame is controlled, thus controlling the length of the stacked fabric. While the technical solution in the aforementioned authorized patent can achieve precise length adjustment, in actual use, when the length is too large, the swing arm swings with a large amplitude, causing the angle between the swing arm and the worktable to gradually increase during the swing. In this situation, there is significant resistance when controlling the motor to reverse, leading to increased motor load and affecting the smoothness of the stacking operation. Furthermore, prolonged exposure to this state can easily damage the motor, reducing the efficiency of the fabric stacking machine and limiting its applicability in different production scenarios, failing to meet the needs of modern textile enterprises for efficient and continuous production.

[0005] Therefore, this utility model proposes a cloth tying machine length adjustment device to solve the above problems.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0040] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0041] Reference Figure 1-8 A fabric grading machine length adjustment device includes a fabric grading machine frame 1, a U-shaped frame 11, two pressure strips 12, a mounting base 2, a cylinder 3, and a fabric guide frame 4. The U-shaped frame 11 is fixedly installed on the top of the fabric grading machine frame 1. The fabric grading machine frame 1 has four guide openings. Slider 122 is slidably installed in two guide openings on the same side. The same mounting shaft 121 is rotatably installed on the side of the two sliders 122 that are close to each other. Two support rods are radially fixedly installed on the mounting shaft 121. The two pressure strips 12 are respectively hinged to the two support rods and arranged in parallel to each other. A motor 123 is fixedly installed on the slider 122 located on the rear side. The output shaft of the motor 123 is axially fixedly connected to the mounting shaft 121, which can control the pressure strips 12 to perform pressing and limiting operations on the fabric as needed.

[0042] Two parallel toothed plates 132 are slidably mounted on the front side of the fabric lining machine frame 1. The two toothed plates 132 are fixedly connected to the corresponding sliders 122. A motor 13 is fixedly mounted on the front side of the fabric lining machine frame 1. A drive gear 131 is fixedly sleeved on the output shaft of the motor 13. The drive gear 131 meshes with the two toothed plates 132 and can adjust the spacing of the mounting shafts 121 on both sides as needed. The mounting base 2 is rotatably mounted on the inner walls of the front and rear sides of the U-shaped frame 11. The cylinder 3 is slidably mounted on the mounting base 2. The fabric guide frame 4 is hinged to the working end of the cylinder 3 and slidably mounted horizontally on the fabric lining machine frame 1.

[0043] A rack 31 is fixedly mounted on the cylinder 3. A mounting slot is provided on the mounting base 2. A rotating pin is rotatably mounted in the mounting slot. A worm gear 34 and a transmission gear 35 are fixedly sleeved on the rotating pin. The transmission gear 35 meshes with the rack 31. A motor 32 is fixedly mounted on the mounting base 2. The output shaft of the motor 32 extends into the mounting slot and a worm 33 is fixedly mounted thereon. The worm 33 meshes with the worm gear 34. The height of the cylinder 3 can be adjusted as needed, and the stability of the cylinder 3 after the height adjustment is completed can be ensured.

[0044] A support bar is fixedly installed inside the U-shaped frame 11. An electromagnet 36 is fixedly installed on the side of the support bar near the mounting base 2. A counterweight block 37 is fixedly installed on the lower side of the mounting base 2 near the electromagnet 36. After the cylinder 3 retracts, the electromagnet 36 attracts the counterweight block 37, causing it to tilt towards the electromagnet 36, thus facilitating the retraction of the cylinder 3. This enables the reversing operation of the guide frame 4. At the same time, the counterweight block 37 causes the center of gravity of the mounting base 2 to shift to the right. This allows the cylinder 3 to retract and control the guide frame 4 to move from the right to the left to below the mounting base 2, thus enabling a direct leftward reversing operation.

[0045] Specifically, in order to ensure that the slider 122 maintains stable sliding within the guide opening, and to precisely control the pressure strip 12 to press stably onto the fabric, and to control the pressure strip 12 to quickly detach when the limit state needs to be released, two slide rods 124 are fixedly installed within the guide opening. Both slide rods 124 are slidably connected to the slider 122, and motor 123 is a servo motor.

[0046] Specifically, two support blocks are fixedly installed on the front side of the fabric lining machine frame 1, and the two toothed plates 132 are slidably connected to the two support blocks to ensure the stability of the toothed plates 132 during operation.

[0047] Specifically, in order to facilitate operators to better control the accuracy of cylinder 3 height adjustment, thereby enabling the adjustment of the code length, a scale 311 is embedded and fixedly installed on the front side of rack 31.

[0048] Specifically, in order to ensure that the guide frame 4 slides stably along the fabric stacking machine frame 1, guide blocks 41 are fixedly installed on both the front and rear sides of the guide frame 4. Strip openings are opened on the inner walls of both the front and rear sides of the fabric stacking machine frame 1, and the two guide blocks 41 are slidably installed in the corresponding strip openings.

[0049] The circuits, electronic components, and module mechanisms involved all employ existing technologies, which can be fully implemented by those skilled in the art, and need no further explanation. The content protected by this application does not involve any improvement to the software, circuits, or methods.

[0050] Working principle:

[0051] In operation, the operator first connects the power supply and passes the fabric to be neatly stacked through the guide frame 4. Simultaneously, the starting motor 123 drives the mounting shaft 121 to rotate, which in turn drives the support rod and pressure strip 12 to rotate until the pressure strip 12 presses and limits one end of the fabric, ensuring the stability of the fabric during stacking. Then, the starting motor 13 drives the drive gear 131 to rotate, which in turn drives the two toothed plates 132 to move closer or further apart. The two toothed plates 132 drive the corresponding sliders 122 to slide within the guide opening until the distance between the pressure strips 12 on both sides matches the length of the fabric. Next, according to the required length, the operator starts the starting motor 32 to drive the worm gear 33 to rotate, which in turn drives the worm wheel 34 to rotate. The worm wheel 34 drives the transmission gear 35 to rotate, which in turn drives the rack 31 to slide on the mounting base 2. The rack 31 then drives the cylinder 3 to slide on the mounting base 2 until the height of the cylinder 3 meets the length adjustment requirements. Meanwhile, the operator can better control the height adjustment accuracy of cylinder 3 by observing the scale 311. Finally, the operator controls cylinder 3 to extend, and cylinder 3 drives the guide frame 4 to slide laterally along the fabric stacking machine frame 1 until the fabric is stacked to the designated position. The operator then controls the pressure strip 12 on that side to press and limit it. Then, the operator controls cylinder 3 to retract, and cylinder 3 drives the guide frame 4 to retract to the initial position. At this time, the electromagnet 36 is activated, and the electromagnet 36 attracts the counterweight block 37, causing the mounting base 2 to move closer to the electromagnet. The direction of 36 is tilted, which facilitates the extension of cylinder 3 again. After cylinder 3 extends again, it drives the guide frame 4 to continue to slide laterally along the fabric stacking machine frame 1, thereby realizing the reversing operation of the guide frame 4. At the same time, under the action of the counterweight block 37, the center of gravity of the mounting base 2 can be shifted to the right. Then, after cylinder 3 retracts again and controls the guide frame 4 to move from the right side to the left to directly below the mounting base 2, there will be a force to the left, thus realizing the direct left reversing operation. This is repeated until the fabric is stacked.
