Description

Ribbon loom driving seat adjustment mechanism

technical field

The invention relates to an adjustment mechanism for a transmission seat of a loom loom, which is an adjustment mechanism arranged between the top frame and the transmission seat of a loom. Through the adjustment mechanism, the position of the transmission seat on the top frame can be adjusted, thereby controlling the tightness of the belt. To achieve the effect of convenient adjustment and precise control.

Background technique

The driving seat of the ribbon loom is a midpoint of the power transmission of the ribbon loom. It is generally fixed on the top frame of the loom. When the power of the main motor is transmitted to the drive shaft in the drive seat along the machine side by the , and then the drive shaft transmits the power downward from the top frame to provide various powers required for the control and operation of the ribbon loom; the general ribbon loom is based on the requirements of the transmission characteristics, which uses a belt to transmit power, but the well-known It is because the belt cannot be cut into long strips like a chain during installation, and then the two ends of the belt are joined after being installed in place; and the belt will inevitably stretch due to fatigue after a period of use, so the operator must timely Adjust the relative position between the two pulleys to facilitate the loading and unloading of the belt or provide the appropriate tension of the belt to ensure the stability of power transmission. This means that the distance between the two opposite pulleys must be designed as an adjustable structure.

In view of the structure of the existing belt loom driving seat, its structural configuration is as shown in Figure 5, and the driving seat 80 is fixedly arranged on the top frame 90, and the driving seat 80 is basically frame-shaped. One side is a joint plate 82 coupled to the top frame 90, and two side plates 84 are combined on both sides of the joint plate 82. On the two side plates 84, a shaft-through hole 840 penetrating is provided. In the shaft-through hole 840 Both sides are provided with elongated holes 842 respectively, and fixed screw holes 844 are formed under the shaft passing holes 840, and the second bearing seat 86 is assembled with the assembly bolts 862 and nuts 864 on the shaft passing shafts outside the two side plates 84 of the transmission seat 80 respectively. At the hole 840, the transmission shaft 70 passes through the bearing 860 inside the bearing seat 86 and the shaft passing hole 840 of the transmission seat 80, and the belt pulley 72 is assembled at the end of the transmission shaft 70; Fix a fixed block 88 to the fixed screw hole 844 outside the side plate 84, and assemble an adjusting screw rod 882 on the fixed block 88; The relative position of the outer side is used to adjust the position of the transmission shaft 70 relative to the transmission seat 80, thereby achieving the effect of adjusting the tightness of the belt.

When the operator wants to replace the belt or adjust the tightness of the belt, he will loosen the assembly bolt 862 that fixes the bearing seat 86, and then push the bearing seat 86 through the adjustment screw 882 on the fixed block 88, so that the assembly bolt 862 can move along the long shape. The hole 842 is shifted to change the relative position between the transmission shaft 70 and the transmission seat 80, and then drives the pulley 72 to shift to adjust the tightness of the belt. After adjusting to the position, tighten the assembly bolt 862 to complete the adjustment. action.

It can be seen from Fig. 6 that the existing adjustment mechanism is operated by the adjustment screw 882 on the outside of the two side plates 84 of the transmission seat 80 to adjust the height of the two bearing seats 86 respectively, which is very likely to cause the bearings on both sides to be damaged during the adjustment. Seats 86 are at different heights, which will affect the concentricity of the bearings 860 in the two bearing seats 86. When the centers of the bearings 860 in the two bearing seats 86 are skewed, it will make the assembly at the end of the transmission shaft 70 Belt pulley 72 produces deflection, and this situation will inevitably cause the belt to squeeze to one side during operation and abnormal wear occurs, which affects the service life of the belt.

In addition, in Fig. 6, it can be seen that the bearing seat 86 on the right side has been pushed upwards, while the bearing seat 86 on the left side is still at a lower position, which is the actual situation of adjusting the existing drive seat 80 ; It can be seen in the figure that when the general operator is adjusting, he must first adjust the bearing seat 86 on one side, and then adjust the bearing seat 86 on the other side. The adjustment screw 882 can only be rotated after the bolt 862 is loosened, but in fact, it is often found that the operator is too lazy to climb up and down on both sides of the loom to loosen the assembly bolt 862, and often loosens the assembly bolt 862 on one side first, that is, rotates the adjustment screw 882. Adjust the relative height of the bearing seat 86 on this side, and then change to the other side for adjustment, but under this operation, if the assembly bolt 862 of the left bearing seat 86 is not loosened, the bearing seat 86 on the right side will be changed. height, then between the transmission shaft 70 and the bearing in the bearing seat 86 on the left side, an abnormal torsion force will be produced, and the structure of the bearing will be destroyed; and the height of the bearing seat 86 on one side is adjusted first, and then the height of the other side is adjusted. On the one hand, the tightness of the belt must be taken into account. It is very difficult to adjust the bearing seats 86 on both sides to the same height. The concentricity of the two bearings 860 is a problem caused by the incomplete design of the existing drive seat adjustment mechanism.
