The rubber roller is driven by the loading cylinder to swing around a hinge point. The utility model discloses a rubber roll also adopts the initiative drive mode, does not need the tension of fabric to provide driving torque, can realize lower tensile continuous operation, avoids causing the damage to the fabric surface. The rubber roller is driven by the loading cylinder and the swing arm to swing up and down, so that the fabric can be conveniently loaded, and meanwhile, the pressure and the tension of the fabric can be conveniently adjusted.
Description
Technical Field
The utility model belongs to the technical field of weaving printing and dyeing equipment, especially, relate to a low tension straight roller device.
Background
The straight roller device is generally used for realizing the functions of padding liquid materials, washing and the like in printing and dyeing equipment, and the fabric shape is easy to control because the fabric is wrapped on the metal roller and the rubber roller in the whole process of the straight roller section. As shown in figure 1, the running path of the straight-roller slot fabric 1 is composed of a lower row of steel rollers 2 and an upper row of rubber rollers 5, the shaft ends of the steel rollers 2 are fixed on the straight-roller slot body through bearing seats, the rubber rollers 5 are located on the two adjacent steel rollers, the fabric 1 firstly passes through the steel rollers 2, then passes through the extrusion point between the steel rollers and the upper sizing roller, then is wrapped on the rubber rollers 5, then enters the next steel roller through the next extrusion point, and is sequentially and repeatedly circulated.
The upper rubber covered roller of the traditional straight roller groove runs in a passive mode, the rotating driving torque comes from the tangential friction force provided by the lower steel roller through the fabric, when the running speed of the machine changes, the rubber covered roller needs additional tangential friction force to obtain the acceleration close to the steel roller, the normal fabric has no serious effect, but when sensitive fabric is processed, the speed difference between the rubber covered roller and the steel roller is increased due to lower processing tension and soft fabric characteristics, and the synchronization failure is caused.
Disclosure of Invention
The utility model aims to provide a mode that sets up driving motor for the rubber roll breaks away from its low tension straight roll groove to the reliance of the tangential friction power that is provided by the fabric to the demand of sensitive fabric.
The utility model discloses a realize above-mentioned purpose, adopt following technical scheme:
a low-tension straight roller groove comprises a lower row of steel rollers and an upper row of rubber rollers, wherein the steel rollers are driven by a motor to rotate, and a fabric is wrapped on the surfaces of the steel rollers and the rubber rollers to run in a transmission manner; the method is characterized in that: the rubber roller is driven by a motor. The rubber roller also adopts a motor-driven active rotation mode, and for low-tension and soft fabrics, the rubber roller can synchronously rotate with the steel roller without depending on the friction force of the fabrics, so that the fabrics are driven to move forwards, and the damage to the surfaces of the fabrics is avoided.
It is further characterized in that: the rubber roller is driven by the loading cylinder to swing around a hinge point. The rubber roller is driven to swing by the loading cylinder, so that the rubber roller can be lifted, and cloth threading or maintenance operation is facilitated.
Further: the shaft end of the rubber roller is installed at one end of the swing frame, and the other end of the swing frame is hinged to the hinged point.
Further: tension detection rollers are arranged between the upper row of adjacent rubber rollers at intervals. The tension of the fabric is detected through the tension detection rollers arranged at intervals and fed back to the driving devices of the steel roller and the rubber roller, so that the tension of the fabric is stable.
Preferably: the swing frame is connected with the hinged point through a bearing, and the shaft end of the rubber roller is connected with the swing frame through a bearing. And the bearing of the rubber roll and the bearing of the swing frame are both self-aligning bearings. The self-aligning bearing is adopted, so that the left end and the right end of the rubber roller and the steel roller can be kept in contact, and the fabric is in a good extrusion state.
Preferably: the diameters of the steel roller and the rubber roller are the same. The same diameter can ensure that the steel roller and the rubber roller have the same linear velocity and angular velocity when rotating synchronously, and ensure the surface quality of the fabric.
It is further characterized in that: after the rubber roller is pressed down, the rubber roller is only contacted with one steel roller arranged at the lower row, so that the fabric has only one extrusion point between the rubber roller and the steel roller.
The utility model discloses a rubber roll also adopts the initiative drive mode, does not need the tension of fabric to provide driving torque, can realize lower tensile continuous operation, avoids causing the damage to the fabric surface. The rubber roller is driven by the loading cylinder and the swing arm to swing up and down, so that the fabric can be conveniently loaded, and meanwhile, the pressure and the tension of the fabric can be conveniently adjusted.

Detailed Description
As shown in figure 2, the low-tension straight roller groove comprises a lower row of steel rollers 2 and an upper row of rubber rollers 5 which have the same diameter, and a fabric 1 is wrapped on the surfaces of the steel rollers 2 and the rubber rollers 5 and runs in a transmission mode. The steel roller 2 and the rubber roller 5 are driven by a motor to rotate. The rubber roller 5 also adopts an active rotation mode driven by a motor, and for low-tension and soft fabrics, the rubber roller can synchronously rotate with the steel roller 2 without depending on the friction force of the fabrics, so that the fabrics 1 are driven to move forward, and the damage to the surface of the fabrics 1 is avoided. Tension detection rollers 8 are arranged between the adjacent rubber rollers 5 on the upper row at intervals. The tension of the fabric is detected by the tension detection rollers 8 arranged at intervals and fed back to the driving devices of the steel roller 2 and the rubber roller 5, so that the stability of the tension of the fabric 1 is ensured.
The axle head of rubber roll 5 passes through aligning bearing 7 to be installed in the one end of rocker 4, and the other end of rocker 4 articulates on pin joint 3 through aligning bearing 7, and rubber roll 5 is driven by loading cylinder 6 and is encircleed the swing of pin joint 3. The rubber roller 5 is driven to swing by the loading cylinder 6, so that the lifting of the rubber roller 5 can be realized, and the cloth threading or maintenance operation is convenient. The self-aligning bearing 7 is adopted, so that the left end and the right end of the rubber roller 5 and the steel roller 2 can be kept in contact, and the fabric 1 is in a good extrusion state.
The utility model discloses during operation, rubber roll 5 only contacts with a steel roll 2 of discharging down after pushing down for fabric 1 only has an extrusion point between rubber roll 5 and steel roll 2.
