Description

Technical Field

[0001] This utility model relates to the field of textile machinery technology, and specifically discloses a novel drive mechanism for needle rollers of a napping machine. Background Technology

[0002] The napping machine is a key piece of equipment in textile finishing. It uses a high-speed rotating needle roller to nap the surface of the fabric, causing the fiber ends to stand up and form a nap layer, thereby giving the fabric a fluffy, soft or special visual effect (such as blankets, peach skin, etc.). Its core component, the needle roller, is usually composed of a roller body with densely arranged steel needles.

[0003] Existing napping machine needle roller drive mechanism, such as Figure 1 As shown, the current method uses a two-stage V-belt drive, including a needle roller body 1, a drive wheel 2, and a drive motor 7. The needle roller body 1 and the drive wheel 2 are connected by a first belt 4. The outer wall of the drive wheel 2 is fixedly connected to a large conversion pulley 5 via a coupling. The output end of the drive motor 7 is fixedly connected to a motor pulley 6. The large conversion pulley 5 and the motor pulley 6 are connected by a second belt. This transmission method has high energy consumption, occupies space, and has complicated parts, resulting in high cost. Therefore, a new type of drive mechanism for the needle roller of a napping machine is needed to solve this problem. Utility Model Content

[0004] This utility model proposes a novel drive mechanism for the needle roller of a napping machine. It adopts a direct-drive motor and a single-stage belt drive, which saves energy, space and cost compared with the traditional solution. Furthermore, the transmission is stabilized by synchronously adjusting the double tension pulleys, which improves the uniformity of napping and the stability of operation.

[0005] This utility model is implemented as follows: a novel drive mechanism for a napping machine needle roller includes a needle roller body and a frame. A direct drive motor is installed on the outer wall of the frame, and a drive wheel is fixedly connected to the output end of the direct drive motor. The needle roller body and the drive wheel are connected by a first belt drive. The outer wall of the frame is provided with two tensioning wheels that abut against the first belt through an adjustment mechanism.

[0006] As a preferred embodiment of the novel drive mechanism for the needle roller of the napping machine according to this utility model, the adjustment mechanism includes a fixed block fixedly connected to the outer wall of the frame. The outer wall of the fixed block is threaded through and threaded with a threaded rod. The upper end of the threaded rod is rotatably connected to a movable block via a bearing. The outer wall of the movable block is hinged to two symmetrically distributed first connecting rods via a hinge seat. The outer wall of the frame is rotatably connected to two second connecting rods via a connecting shaft. The two tensioning wheels are rotatably connected to the outer wall of the second connecting rods via connecting shafts. The two first connecting rods are rotatably connected to the two second connecting rods via connecting shafts.

[0007] In a preferred embodiment of the novel drive mechanism for the needle roller of a napping machine according to this utility model, the moving block abuts against the frame.

[0008] As a preferred embodiment of the novel drive mechanism for a napping machine needle roller according to this utility model, a handle is fixedly connected to the outer wall of the threaded rod.

[0009] In a preferred embodiment of the novel drive mechanism for the needle roller of a napping machine according to this utility model, the upper end of the first connecting rod is rotatably connected to the middle part of the second connecting rod via a coupling shaft.

[0010] The beneficial effects of this utility model are:

[0011] 1. The needle roller drive mechanism of this raising machine adopts a direct drive motor combined with a single-stage belt drive, which significantly reduces energy consumption and space occupation compared with the traditional two-stage transmission scheme. Actual measurements show that a single 15kW motor can save up to 67,900 kWh of electricity per year.

[0012] 2. The two tensioning pulleys are synchronously and precisely adjusted through a threaded rod-connecting rod mechanical linkage. This design keeps the belt tension balanced and stable, and the adjustment process is simple and requires no disassembly. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0019] Please see Figure 2-3 A novel drive mechanism for a napping machine needle roller includes a needle roller body 1 and a frame 9. A direct drive motor 8 is installed on the outer wall of the frame 9. A drive wheel 2 is fixedly connected to the output end of the direct drive motor 8. The needle roller body 1 and the drive wheel 2 are connected by a first belt 4. Two tensioning wheels 3 that abut against the first belt 4 are provided on the outer wall of the frame 9 through an adjustment mechanism.

[0020] In this embodiment: the direct drive motor 8 is started, which drives the drive wheel 2 to rotate, and then drives the needle roller body 1 to rotate through the first belt 4. This transmission method changes from the previous two-stage transmission of V-belt to a single-stage transmission of V-belt, which saves energy, saves space, and also saves costs. According to the calculation of a 15kW three-phase asynchronous motor, the annual cumulative energy saving of a single motor is about 67,900 kWh (15kW). Moreover, the position of the two tensioning wheels 3 can be adjusted according to the belt tension through the adjustment mechanism to make the needle roller body 1 rotate stably.

[0021] As a technical optimization of this utility model, the adjustment mechanism includes a fixed block 10 fixedly connected to the outer wall of the frame 9. A threaded rod 11 is threaded through and threaded to the outer wall of the fixed block 10. A movable block 12 is rotatably connected to the upper end of the threaded rod 11 via a bearing. Two symmetrically distributed first connecting rods 13 are hinged to the outer wall of the movable block 12 via a hinge seat. Two second connecting rods 14 are rotatably connected to the outer wall of the frame 9 via a coupling shaft. Two tensioning wheels 3 are rotatably connected to the outer wall of the second connecting rods 14 via coupling shafts. The two first connecting rods 13 are rotatably connected to the two second connecting rods 14 via coupling shafts.

[0022] In this embodiment: rotating the threaded rod 11 causes the moving block 12 to move upward or downward, which in turn drives the two first connecting rods 13 to drive the two second connecting rods 14 to rotate synchronously relative to each other or in opposite directions. The two second connecting rods 14 further drive the two tensioning wheels 3 to move synchronously relative to each other or in opposite directions, thereby adjusting the distance between the two tensioning wheels 3, so that the first belt 4 maintains close contact with the needle roller body 1 and the drive wheel 2, so that the power can be stably transmitted to the needle roller body 1.

[0023] As a technical optimization of this utility model, the movable block 12 abuts against the frame 9.

[0024] In this embodiment: by abutting the moving block 12 against the frame 9, the moving block 12 is prevented from rotating axially with the threaded rod 11.

[0025] As a technical optimization of this utility model, the outer wall of the threaded rod 11 is fixedly connected with a handle.

[0026] In this embodiment, a handle is fixedly connected to the outer wall of the threaded rod 11 to facilitate rotation of the threaded rod 11.

[0027] As a technical optimization of this utility model, the upper end of the first connecting rod 13 is rotatably connected to the middle part of the second connecting rod 14 via a coupling.

[0028] In this embodiment, the upper end of the first connecting rod 13 is rotatably connected to the middle part of the second connecting rod 14 via a coupling, so that the second connecting rod 14 can be rotated by the first connecting rod 13.

[0029] The working principle and usage process of this utility model: When in use, the direct drive motor 8 is started, the direct drive motor 8 drives the drive wheel 2 to rotate, and then drives the needle roller body 1 to rotate through the first belt 4. This transmission method changes from the previous two-stage transmission of V-belt to a single-stage transmission of V-belt, which saves energy, saves space, and also saves costs.

[0030] When adjusting the tension wheel 3, the threaded rod 11 is rotated, which drives the moving block 12 to move up or down. This, in turn, drives the two first connecting rods 13 to rotate the two second connecting rods 14 synchronously or in opposite directions. The two second connecting rods 14 further drive the two tension wheels 3 to move synchronously or in opposite directions, thereby adjusting the distance between the two tension wheels 3. This ensures that the first belt 4 is in close contact with the needle roller body 1 and the drive wheel 2, so that the power can be stably transmitted to the needle roller body 1.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
