Screw rod rotates, drives the mount pad through the nut and reciprocates along guider, realizes the regulation of the back-and-forth movement of leather sheath roller on the mount pad, because the nut passes through spacing guider and installs on the mount pad, and is provided with the spring between nut and mount pad, like this, on the fixed basis in nut position, the leather sheath roller on mount pad, mount pad can compress the spring, under the effect of spring, has certain floating (along the mount pad in the front-back direction) effect for the nut, realizes adjusting the tractive force of fabric.
Specifically, the guiding device is a guiding rod, and the mounting seat moves on the guiding rod. As another structure, the guiding device comprises a sliding groove and a sliding block matched with the sliding groove, the sliding groove is positioned on the mounting seat, the sliding block is positioned on the base, or the sliding groove is positioned on the base, and the mounting seat moves back and forth on the base through the matching of the sliding groove and the sliding block.
The limiting guide device can realize the limiting effect on the movement of the nut on the mounting seat (namely limiting the maximum movement distance of the nut) while playing a guiding role on the movement of the nut on the mounting seat. In order to be convenient for realize above-mentioned function, spacing guider is the guide bar, guide bar one end is installed on the mount pad, the nut has the walking hole, the guide bar is installed in the walking hole, guide bar one end has the spacing head, the spacing head is greater than the walking hole. Thus, the nut can only move between the mounting point of the guide rod and the limiting head.
In order to facilitate installation, the installation hole is a step hole, and the spring is sleeved outside the screw rod and installed in the installation hole, so that one end of the spring is limited in the step hole, and the other end of the spring is limited by the nut. When the nut and the mounting seat are extruded, the spring is contracted, the nut and the mounting seat are close to each other (at the moment, the distance between the leather sleeve roller and the corresponding roller is increased), and after the extrusion force disappears, the spring is reset to drive the nut and the mounting seat to separate (at the moment, the distance between the leather sleeve roller and the corresponding roller is reduced).
In order to fix the screw, two ends of the screw are arranged on the base through bearings.
The screw rod can be adjusted by manpower, and also can be driven by external force, for example, one end of the screw rod is connected with a motor, and the motor drives the screw rod to rotate. At this time, in order to reduce the reaction force of fabric and drive the screw rod to motor one side displacement damage motor shaft, at the one end of connecting the motor, the screw rod passes through angular contact ball bearing and installs on the base. The angular contact ball bearing plays a role in isolation, and the motor shaft is prevented from being damaged by axial force.
The utility model has simple structure, realizes the adjustment of the traction force of the fabric under the action of the spring between the mounting seat and the nut on the basis of the fixed position of the mounting seat for mounting the leather sleeve roller, is suitable for the traction of the fabric with different thickness, and can be automatically adjusted.
Drawings
The utility model will be described in further detail with reference to the drawings and the detailed description.
FIG. 1 is a schematic diagram of the structure of the present utility model.
Fig. 2 is a schematic view of the structure of the mounting base and the base of the present utility model.
Fig. 3 is a schematic view of a base structure of the present utility model.
Detailed Description
As shown in fig. 1 to 3, the sub-roller unit (a plurality of sub-roller units are arranged together to form a roller) includes a leather sheath roller 1, the leather sheath roller 1 is mounted on a mounting seat 3, and the leather sheath roller 1 is driven to rotate on the mounting seat 3. Specifically, the leather sheath roller 1 is installed on the installation seat 3 through the support frames 2 on both sides, and on the support frames 2, the leather sheath roller 1 is driven to rotate through a motor, so that the function of a roller is realized.
The mount pad 3 passes through guider and installs on base 4, and base 4 can be installed on the horizontal pole through base mounting hole 5. The guide device is a guide rod 7, two guide rods 7 can be arranged left and right, and the mounting seat 3 moves on the guide rods 7. As another implementation structure, the guiding device comprises a sliding groove and a sliding block matched with the sliding groove, the sliding groove is positioned on the mounting seat 3, the sliding block is positioned on the base 4, or the sliding groove is positioned on the base 4, the sliding block is positioned on the mounting seat 3, and the mounting seat 3 moves back and forth on the base 4 through the matching of the sliding groove and the sliding block.
The mounting seat 3 is provided with a mounting hole 8, a screw rod 9 is arranged in the mounting hole 8, the screw rod 9 is rotatably arranged on the base 4, specifically, two ends of the screw rod 9 are arranged on the base 4 through bearings 14, the screw rod 9 can be adjusted by manpower or driven by external force, for example, one end of the screw rod 9 is connected with the motor 6 through a coupler 10, and the motor 6 drives the screw rod 9 to rotate. At one end of the connecting motor 6, the screw 9 is arranged on the base 4 through an angular contact ball bearing 15, and the angular contact ball bearing 15 plays a role in isolation, so that the motor shaft is prevented from being damaged by axial force. When the reaction force of the fabric drives the screw rod 9 to move to one side of the motor, the angular contact ball bearing 15 avoids damaging a motor shaft.
