[0002] As we all know, in the pultrusion process, the straightness of the pultruded product is one of the key parameters for determining whether the pultrusion process is stable and whether the pultruded product meets the standards. Poor straightness will lead to a large amount of product waste, and the pultruded finished product will also be scrapped. In the double-exit pultrusion process, controlling the straightness of the double-exit pultruded product is particularly important and challenging. Existing double-exit pultrusion production lines are faced with the problem of too narrow center distance between double-exit pultruded products and small gaps between products. The existing single-exit straightness clamping device can no longer meet the straightness control requirements of double-exit products. Summary of the Invention

[0014] In the figure, the utility model is provided with a main frame 1, which consists of a bottom plate and two side plates. Two guide rails 9 are installed in parallel at the lower position between the two side plates. Two sliders 8 are mirror-set on each guide rail 9. An L-shaped mobile platform 3 is fixed on the slider 8. A wire hole extender 10 is connected to the outside of the mobile platform 3. A fixed wire hole 2 is processed on the top of the mobile platform 3. A screw connected to the wire hole extender 10 is screwed into the fixed wire hole 2. The other end of the wire hole extender 10 is threadedly matched with one end of the adjusting screw 11. The other end of the adjusting screw 11 is positioned on the outside of the side plate through a locking retaining ring 6. A scale 5 is installed on the inner side of the upper end of the side plate. A width adjustment slot 7 is processed on the lower side of the mobile platform 3. Two sets of T-nuts 18 are vertically installed at the lower part of the width adjustment slot 7. The lower end of the screw 13 is screwed together with the T-nut 18. The bottom of the main shaft screw 13 is provided with a step and is tightly fitted with a fixing gasket 17. The main shaft screw 13 is provided with an inner bearing support sleeve 15, and the inner bearing support sleeve 15 is provided with an outer bearing support sleeve 16 through the bearing 14. The main shaft screw 13, the bearing 14, the inner bearing support sleeve 15, the outer bearing support sleeve 16, the fixing gasket 17 and the T-nut 18 constitute the clamping roller 4. The two ends of the bottom plate are processed with long horizontal fixing slots 19 for fixing the main frame 1 and moving left and right for adaptive installation. A front plate 21 is installed between the front sides of the two side plates, and the front plate 21 is processed with long vertical fixing slots 20 for fixing the main frame 1 and realizing the up and down movement of the device to meet the installation requirements of different scenarios.

[0015] The two pultruded products 12 after solidification are passed through the two clamping rollers 4 on the left and the two clamping rollers 4 on the right of the device (as shown in FIG. Figure 2 、 3As shown), it is then pulled out through the traction machine. Before starting, first screw the main shaft screw 13 on the top of the clamping roller 4 to adjust the gap width between the left and right clamping rollers 4 to be consistent with the width of the pultruded product 12. If the straightness of the pultruded product 12 changes, it is necessary to loosen the locking ring 6 before turning the adjusting screw 11. Then, according to the length of the cut product, measure the bending direction and value of its straightness. According to the bending direction, screw the adjusting screw 11 to push the mobile platform 3 to the right or left. The mobile platform 3 then drives the clamping roller 4 and the slider 8 to move on the track 9, that is, drives the pultruded product 12 to move left and right. After the adjustment is completed, tighten the locking ring 6. As shown Figure 4 As shown, the inner bearing support sleeve 15 and the outer bearing support sleeve 16 provide radial support and fixation for the bearing 14. The inner bearing support sleeve 15 is tightly fitted with the spindle screw 13, the outer bearing support sleeve 16 (i.e., the roller surface) is tightly fitted with the outer circle of the bearing 14, and the inner circle of the bearing 14 is tightly fitted with the spindle screw 13. This forms a stable roller shaft structure. The spindle screw 13 is equipped with a T-nut 18, which can be inserted into the width adjustment slot 7. When the spindle screw 13 is rotated, the T-nut 18 is stuck, and the spindle screw 13 can be tightened. In addition, the bottom of the spindle screw 13 is provided with a step and is tightly fitted with a fixing gasket 17. Its function is to provide a larger contact surface with the movable platform 3 and provide a handle for tightening the spindle screw 13, so that the clamping roller 4 is firmly fixed.
