Description

Technical Field

[0001] This utility model relates to the field of sanding processing technology, and in particular to a sanding machine that facilitates adjustment of roller spacing. Background Technology

[0002] The vertical nine-roller napping machine is a specialized piece of equipment used for napping textile fabrics. It gets its name from its core configuration of nine functional rollers and the fact that the fabric enters from the front and exits from the rear. It is often used to give pure cotton, chemical fiber and other fabrics a soft and delicate feel.

[0003] Most conventional nine-roller napping machines are equipped with two tension rollers to ensure tension during the core napping and fabric feeding / discharging stages. One of them is located between the napping roller group and the fabric feeding drive roller to stabilize the fabric tension in advance and prevent uneven napping caused by fabric loosening during napping. The other is located between the napping roller group and the discharge roller to prevent the fabric from deviating or wrinkling during the discharge stage after napping.

[0004] When using tension rollers, the spacing of the tension rollers needs to be adjusted to match the corresponding tension because the thickness and weight of the fabric to be abraded vary. Traditional tension rollers are mostly structured with separate adjustments at both ends. It is difficult to ensure that the adjustment distance or pressure at both ends is completely consistent during manual operation. If the number of turns of the bolts at both ends is different, it will cause the roller to tilt, which may cause the fabric to be torn or even damage the tension roller. Moreover, manual adjustment is prone to safety hazards. When using a cylinder-type adjustment method, if the piston rod movement speed is different, it will also cause uneven force on the tension roller, which will eventually cause the fabric to deviate during transmission and result in uneven abrasion depth.

[0018] 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.

[0019] Example: This example provides a grinding machine with easily adjustable roller gap. See [link to example]. Figure 1-4 The system includes a frame mounted on a napping machine, and a tension roller body 1 mounted on the frame. This napping machine is a vertical napping machine, typically equipped with two tension rollers; however, only one tension roller is described here. The tension roller and other rollers are vertically mounted on the vertical napping machine. A transmission component 3 is installed inside the napping machine. The transmission component 3 is configured to drive the tension roller body 1 to move relative to the frame, thereby adjusting the distance between the tension roller body 1 and the fabric. Both ends of the tension roller body 1 are detachably mounted with sliders 2 via mounting components 4. The mounting components 4 are used to adjust the tension roller body 1. The tension roller body 1 is fixed together with the slider 2. The two sliders 2 are arranged symmetrically and are convex in shape. The transmission component 3 includes a pair of threaded rods 301 with the same pitch. The threaded rods 301 are threaded through the sliders 2 and are used to drive the sliders 2 to move. The mounting component 4 includes fixing blocks 401 rotatably connected to both ends of the tension roller body 1. The two fixing blocks 401 are arranged symmetrically. A T-shaped block 402 is fixed on the side of the fixing block 401 away from the tension roller body 1. The fixing blocks 401 and the T-shaped block 402 are detachably installed inside the sliders 2.

[0020] Since the fixed block 401 is rotatably connected to the roller shaft of the tension roller body 1, in equipment such as the napping machine, the fabric (not shown in the figure) is always conveyed in close contact with the surface of the tension roller body 1. When the traction roller on the napping machine drives the fabric to move continuously, friction will be generated between the fabric and the roller surface of the tension roller body 1. This friction will be converted into torque to drive the tension roller body 1 to rotate. Since the tension roller body 1 itself is a freely rotatable structure, under the action of this torque, it will passively rotate synchronously with the conveying direction of the fabric. The friction of the fabric on the roller surface is sufficient to drive the tension roller body 1 to rotate smoothly, and the rotation speed will change synchronously with the fabric conveying speed, always maintaining a match.

[0021] The inner side of the frame is provided with a pair of symmetrical first slide grooves. The first slide grooves are convex in shape. Each slider 2 slides in the corresponding first slide groove. Each threaded rod 301 passes through the corresponding slider 2 and is rotatably connected in the corresponding first slide groove. The transmission component 3 also includes a synchronous pulley 302. One end of each pair of threaded rods 301 is fixedly provided with a synchronous pulley 302. The outer sides of the two synchronous pulleys 302 are fitted with the same synchronous belt 303. Driving one threaded rod 301 can drive the other threaded rod 301 to rotate synchronously. The transmission component 3 also includes a motor 304. The output shaft of the motor 304 is fixedly connected to the end of one of the threaded rods 301. The motor 304 is used to provide power to the threaded rod 301.

[0022] The motor 304 can be a YR series model. The YR series is equipped with a friction disc damping brake device, which stops quickly and can achieve rapid forward or reverse rotation. By quickly switching between forward and reverse rotation of the motor 304, the motor 304 can drive the threaded rod 301 to quickly switch between forward and reverse rotation, which facilitates timely adjustment of the roller pitch. Since the two threaded rods 301 have the same pitch and rotate synchronously, the tension roller body 1 can always remain horizontal when the roller pitch is adjusted.

[0023] Both ends of the threaded rod 301 are provided with smooth rod sections. When the slider 2 slides to the smooth rod section, the threaded rod 301 rotates freely, preventing the slider 2 from getting stuck due to excessive rotation of the threaded rod 301. This avoids the tension roller body 1 from overtraveling due to excessive rotation of the threaded rod 301. Furthermore, since the slider 2 slides in the groove on the inner wall of the frame, when the operator pushes the slider 2 to the edge of the threaded section, the rotating thread can quickly engage with the internal threaded hole of the slider 2, thereby driving the slider 2 to continue moving through the threaded transmission, which improves the safety of the tension roller body 1 during adjustment.

[0024] The grinding machine of this utility model, by setting the transmission component 3, realizes the function of adjusting the roller gap of the tension roller body 1. The synchronous rotation of the two threaded rods 301 ensures that the tension roller body 1 can always remain horizontal when adjusting the roller gap, so that the roller body of the tension roller body 1 will not tilt when adjusting the roller gap, and the fabric will not deviate when the tension roller body 1 is conveying the fabric.

[0025] In the specific implementation process, such as Figure 2 , Figure 3 and Figure 4 As shown, a second slide groove is provided on one side of the slider 2. The second slide groove is T-shaped, and the T-shaped block 402 slides within the second slide groove. Since the T-shaped block 402 is fixedly connected to the fixed block 401, the tension roller body 1 can slide within the slider 2 through the T-shaped block 402, facilitating the installation of the tension roller body 1. The mounting component 4 also includes two U-shaped plates 403. The U-shaped plates 403 can be made of alloy steel, which has high tensile strength, typically 800-1200MPa, and a yield strength generally up to 600- With a strength of 900MPa and high rigidity at room temperature, it is not prone to plastic deformation even under long-term pressure and equipment vibration. The U-shaped plate 403 is used to fix the T-shaped block 402 inside the slider 2. The T-shaped block 402 is installed in the second groove opened on the slider 2 through the U-shaped plate 403. Each U-shaped plate 403 is set on the same side of the slider 2 and the T-shaped block 402. The same side of the slider 2 and the T-shaped block 402 has a slot with the same shape and depth as the U-shaped plate 403. The U-shaped plate 403 is engaged in the slot.

[0026] Both sides of the U-shaped plate 403 are threaded with bolts 404. The two bolts 404 are threaded through the U-shaped plate 403 and the slider 2 respectively and are threaded on both sides of the T-shaped block 402. Since both sides of the U-shaped plate 403 and the slider 2 have threaded holes, and both sides of the T-shaped block 402 have threaded grooves, and the threaded grooves and threaded holes are arranged coaxially, the bolts 404 are tightened so that the threads of the bolts 404 can be threaded through the U-shaped plate 403 and the slider 2 and threaded in the T-shaped block 402, so that the T-shaped block 402 is fixed in the slider 2. At this time, there is no gap between the T-shaped block 402, the slider 2 and the U-shaped plate 403, so that the tension roller body 1 will not shift on its own under the restriction of the slider 2.

[0027] The grinding machine of this utility model, by setting the mounting part 4, enables the tension roller body 1 to be mounted on the slider 2 through the mounting part 4, which facilitates the installation and disassembly of the tension roller body 1. By setting the T-shaped block 402, the tension roller body 1 can slide in the slider 2 through the T-shaped block 402, which facilitates the insertion or removal of the tension roller body 1 from the slider 2. By setting the U-shaped plate 403 and the bolt 404, the T-shaped block 402 can be tightly fixed in the slider 2, so that the tension roller body 1 will not shift on its own during use.

[0028] Specifically, the working principle and operation method of this utility model are as follows: In specific operations, the procedures are as follows; When installing the tension roller body 1, slide the T-shaped blocks 402 on both sides of the tension roller body 1 into the second groove opened on the slider 2, and engage the U-shaped plate 403 in the groove opened on the outside of the slider 2 and the T-shaped block 402. Since threaded holes are opened on both sides of the U-shaped plate 403 and the slider 2, and threaded grooves are opened on both sides of the T-shaped block 402, and the threaded grooves and threaded holes are arranged coaxially, tighten the bolt 404 so that the thread of the bolt 404 can thread through the U-shaped plate 403 and the slider 2 and be threadedly installed in the T-shaped block 402, so that the T-shaped block 402 is fixed in the slider 2. When it is necessary to adjust the roller gap of the tension roller body 1, start the motor 304 to drive a threaded rod 301 to rotate. Under the action of the synchronous pulley 302 and the synchronous belt 303, the two threaded rods 301 rotate synchronously, so that the slider 2 can be displaced under the rotation of the threaded rod 301, and the tension roller body 1 can be displaced synchronously with the slider 2.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
