Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a transmission device and a cloth rolling rack. Background Art

[0002] During the textile process, the machine's forward and reverse rotation modes need to be adjusted to suit the fabric's processing characteristics. This change in the machine's forward and reverse rotation also causes the reel gear on the reel to rotate in sync. However, the reel gear must maintain a constant forward rotation for proper fabric winding.

[0003] In the prior art, the machine is connected to the gearbox gear via bevel gears, which are then connected to the cloth roll gear via a chain drive. Therefore, when the machine's direction of rotation changes, the force is transmitted to the gearbox gear via the bevel gears, and then to the cloth roll gear via the chain drive, thereby driving the cloth roll gear to rotate synchronously. Therefore, to ensure that the cloth roll gear always rotates clockwise, when the machine's direction of rotation changes, the position of the bevel gears in the gearbox is changed, thereby changing the direction of the force transmitted to the gearbox gear by the bevel gears. This in turn adjusts the direction of the cloth roll gear accordingly to maintain clockwise rotation.

[0004] However, replacing the position of the bevel gear in the gearbox requires lifting out the entire cloth frame, which is labor-intensive, time-consuming, and has the risk of being hit or crushed. Utility Model Content

[0005] The purpose of the utility model is to provide a transmission device and a cloth rolling rack to solve the technical problem in the prior art that the direction of the cloth rolling gear is difficult to adjust.

[0021] The utility model has the advantages of:

[0022] The transmission device provided by the utility model is based on the principle that the transmission directions of two gears are same when the two gears are on the same side of the chain, and the transmission directions of the two gears are opposite when the two gears are on the opposite sides of the chain.

[0031] Embodiment one

[0032] Referring to Figure 1 And Figure 2The utility model discloses a transmission device including wave box gear 2, cloth winding gear 1, transmission chain 3 and auxiliary gear 4. Among them, wave box gear 2 is connected with machine table and can rotate synchronously with machine table, transmission chain 3 cloth winding gear 1 is connected with wave box gear 2 through transmission chain 3, and transmission chain 3 is detachably engaged with cloth winding gear 1 and wave box gear 2 respectively, transmission chain 3 and auxiliary gear 4 are selectively engaged, when transmission chain 3 and auxiliary gear 4 are engaged, wave box gear 2 and cloth winding gear 1 are located at both sides of transmission chain 3, otherwise, wave box gear 2 and cloth winding gear 1 are located at the same side of transmission chain 3.

[0033] The utility model discloses a transmission device, according to two gears in the same side of chain, then the transmission direction of two gears is same, two gears in both sides of chain, then the transmission direction of two gears is opposite. If machine table is reversed, under the condition that the position of bevel gear is not changed, the steering of wave box gear 2 will be reversed synchronously, at this time, make transmission chain 3 and auxiliary gear 4 engage, let cloth winding gear 1 and wave box gear 2 be located at both sides of transmission chain 3, so that cloth winding gear 1 can be realized just in the case where wave box gear 2 is reversed, if machine table is reversed, under the condition that the position of bevel gear is not changed, the steering of wave box gear 2 will be reversed synchronously, at this time, disconnect the engagement of transmission chain 3 and auxiliary gear 4, let cloth winding gear 1 and wave box gear 2 be located at the same side of transmission chain 3, so that cloth winding gear 1 also carries out in the case where wave box gear 2 is reversed. In conclusion, whether machine table is reversed or not, under the condition that the cloth rack is not disassembled again, the position of bevel gear is not changed, by adjusting the position of transmission chain 3, can keep cloth winding gear 1 always reversed, effectively solve the problem of cloth winding gear 1 steering in prior art, save the cost of manpower, shorten the adjustment time, improve the work efficiency.

[0034] The specific structure of the transmission device is described below.

[0035] Specifically, the auxiliary gear 4 is provided with at least two, and the plurality of auxiliary gears 4 are arranged at intervals. The plurality of auxiliary gears 4 work cooperatively to share the load in the transmission process, making the entire transmission process more stable, reducing faults and wear caused by uneven stress on a single auxiliary gear 4, and the cooperative action of the plurality of auxiliary gears 4 helps to reduce transmission error, making the rotation of the cloth winding gear 1 more accurate, thereby ensuring the quality of the cloth winding operation.

[0036] Further, the center distance of two adjacent auxiliary gears 4 is adjustable. By adjusting the center distance of adjacent auxiliary gears 4, different installation spaces and transmission layout requirements can be better adapted to, so that the transmission device can be installed and used in various complex working conditions, improving the adaptability and versatility of the transmission device. In addition, according to the actual working conditions, the center distance of the auxiliary gear 4 is reasonably adjusted, so that the transmission chain 3 can maintain appropriate tension during operation, reduce the slack or tightness of the transmission chain 3, and reduce the wear and fatigue of the transmission chain 3.

[0037] Specifically, each auxiliary gear 4 is installed on an independent sliding seat, and the sliding seat is connected with the fixed frame of the transmission device through a guide rail. The sliding seat is provided with a screw hole and is equipped with an adjusting bolt. One end of the adjusting bolt abuts against the sliding seat, and the other end passes through the long strip-shaped adjusting hole on the fixed frame and is fixed by a nut. When it is necessary to adjust the center distance of two adjacent auxiliary gears 4, the nut is first loosened, and then the adjusting bolt is rotated. The rotation of the adjusting bolt drives the sliding seat to move along the guide rail, thereby changing the position of the auxiliary gear 4 and realizing the adjustment of the center distance. After the adjustment is completed, the nut is tightened to fix the position of the sliding seat and ensure the stability of the auxiliary gear 4 in operation.

[0038] In addition, in order to ensure the smoothness and precision of the movement of the sliding seat, the guide rail adopts a high-precision linear guide rail and is regularly lubricated with lubricating grease.

[0039] In addition, the cloth winding gear 1 is located between the auxiliary gear 4 and the gearbox gear 2. The cloth winding gear 1 in the intermediate position can more directly receive the force from the auxiliary gear 4 and the gearbox gear 2, reduce the loss and deviation of the force in the transmission process, and help to balance the stress distribution of the entire transmission system.

[0040] Specifically, the gear ratio of the gearbox gear 2 and the cloth winding gear 1 is 1:2 to 1:5. Such a gear ratio range can ensure that the cloth winding gear 1 obtains appropriate speed and torque under the drive of the gearbox gear 2, meeting the requirements of different cloth winding processes. For cloth winding operations that require higher torque but lower speed, a larger gear ratio can provide sufficient power; and for some cases that require higher speed, a smaller gear ratio can increase the speed of the cloth winding gear 1.

[0041] More specifically, the diameter of the winding gear 1 is larger than the diameter of the gearbox gear 2. The winding gear 1 with larger diameter has relatively lower rotating speed and relatively larger torque under the same transmission ratio, which is beneficial to provide sufficient force to wind the cloth during the winding process, especially for the cloth with heavy weight or requiring larger tension, so as to ensure the tightness and stability of the winding. Moreover, the larger diameter of the winding gear 1 can reduce the linear speed change per revolution, so that the winding speed is more uniform, thereby improving the precision and quality of the winding, and reducing the shaking and deviation of the cloth during the winding process. In some cases, the working speed of the winding gear 1 can be changed by adjusting the rotating speed of the gearbox gear 2. Since the winding gear 1 has larger diameter, even if the rotating speed of the gearbox gear 2 changes to a certain extent, the speed change of the winding gear 1 is relatively small, which is beneficial to more accurately control the winding speed.

[0042] During the operation of the device, the tension of the transmission chain 3 can change due to factors such as temperature change and component wear, therefore, the transmission device further comprises a tension gear 5, which is meshingly connected with the transmission chain 3, and the tension gear 5 is used to adjust the tension of the transmission chain 3. The presence of the tension gear 5 can be conveniently adjusted at any time, so that the transmission device can adapt to different working conditions, and ensure the close meshing between the transmission chain 3 and each gear, thereby effectively transmitting power and ensuring transmission efficiency.

[0043] Specifically, the tension gear 5 is installed on a movable bracket. The bracket is fixed on the fixed frame of the transmission device by bolts, and a long strip-shaped adjustment hole is provided on the fixed frame. The wheel shaft of the tension gear 5 is installed at one end of the bracket, and the wheel shaft and the bracket are connected by a bearing to ensure that the tension gear 5 can rotate freely. When it is necessary to adjust the tension of the transmission chain 3, the bolts fixing the bracket are first loosened. Then, according to the relaxation of the transmission chain 3, the bracket is pushed along the adjustment hole, so that the tension gear 5 approaches or moves away from the transmission chain 3. When the tension gear 5 moves to the appropriate position and the transmission chain 3 reaches the required tension, the bolts are tightened again to fix the position of the bracket, thereby completing the adjustment process of the tension of the transmission chain 3.

[0044] More specifically, the tension gear 5 is located between the gearbox gear 2 and the winding gear 1, which can better balance the transmission force between the gearbox gear 2 and the winding gear 1, reduce the gear wear and failure caused by uneven distribution of transmission force, and also make the path of the transmission chain 3 more reasonable, reduce the bending and twisting of the transmission chain 3, and reduce the tension change of the transmission chain 3, thereby improving the efficiency and stability of the transmission.

[0045] In other embodiments, the tension gear 5 can also be arranged at other positions of the transmission chain 3, and the arrangement position and number of the tension gear 5 are not limited herein and can be adaptively adjusted according to actual needs.

[0046] It is worth noting that the surface of the tension gear 5 is made of wear-resistant material to increase the friction with the transmission chain 3 and reduce the wear of the transmission chain 3. Meanwhile, a locking nut is arranged on the axle of the tension gear 5 to prevent the axle from loosening during operation.

[0048] The embodiment of the present application also provides a cloth winding frame, which comprises a main body, and the main body is provided with the transmission device described above, so that the cloth winding gear 1 can be quickly and accurately adjusted according to the change of the machine turning, and the turning is always kept in order, so that efficient and stable cloth winding operation is realized, and the production efficiency is improved. Since the transmission device avoids the complex disassembly and assembly operation for adjusting the turning of the cloth winding gear 1, the operation of the cloth winding frame is more convenient, and the working strength of the operator is reduced. Meanwhile, the risk of equipment damage caused by disassembly and assembly is also reduced, the maintenance cost and the maintenance difficulty are reduced, the cloth frame does not need to be lifted out as a whole for adjustment, the probability of safety accidents such as bruising and crushing is reduced, and a safer working environment is provided for the operator.
