Description

Technical Field

[0001] This application belongs to the technical field of pultruded sheet manufacturing, and specifically relates to a device for correcting the deviation of the release cloth in pultruded sheet production. Background Art

[0002] The use of the release cloth for pultruded sheet production is to separate the inner surface of the mold from the pultruded sheet through the release cloth when the mold extrudes the pultruded sheet, so as to prevent the surface of the pultruded sheet from adhering to the inner surface of the mold and making it difficult for the pultruded sheet to be demolded from the mold. The production of pultruded sheets is mainly carried out by solidifying the fiber bundle and resin together through extrusion. At the beginning, one end of the fiber bundle wound on the reel is pulled to one end of the production line, and then the reel winding the fiber bundle is coaxially sleeved on the rotation at the other end of the production line. After that, the fiber bundle between the two ends of the production line is continuously solidified by resin, and then the pultruded sheet is formed by extrusion through the mold. At this time, the mold is also located between the two ends of the production line, and the formed pultruded sheet is wound and collected by another reel. Therefore, when using the release cloth to prevent the pultruded sheet from adhering to the inner surface of the mold, it is necessary to make the release cloth parallel to the pultruded sheet and the projection of the length line of the release cloth in the horizontal plane parallel to the projection of the length line of the production line in the horizontal plane. If there is an angle between the projection of the length line of the release cloth in the horizontal plane and the projection of the length line of the production line in the horizontal plane, the release cloth cannot completely separate the pultruded sheet from the mold during the process of the mold extruding the pultruded sheet. Therefore, when installing the release cloth reel, it is necessary to adjust the angle between the projection of the length line of the release cloth in the horizontal plane and the projection of the length line of the production line in the horizontal plane. In the prior art, a reel wound with a release cloth is sleeved on a roller that is perpendicular to the length line of the production line and horizontal. Then, the worker visually estimates the angle (deviation correction) between the projection of the length line of the release cloth in the horizontal plane and the projection of the length line of the production line in the horizontal plane by means of line of sight standard, and then adjusts the axial position of the reel on the roller. Finally, the adjusted reel is relatively fixed to the roller. This method is inaccurate and highly correlated with the worker's work experience. Therefore, it is necessary to design a device for correcting the deviation of the release cloth during the production of pultruded sheets. Summary of the Utility Model

[0003] The main purpose of this application is to address the shortcomings of the prior art. By using a linear mover in cooperation with a reel installer on a rotating motor, a device for correcting the deviation of the release cloth in pultruded sheet production is designed, which can accurately and specifically adjust the offset of the release cloth relative to the pultruded sheet, and solves the problems of inaccurate deviation correction caused by visual estimation and high correlation with the worker's work experience.

[0008] Preferably, the drum installer includes a screw rod and two limit blocks. One end of the screw rod is coaxially and fixedly connected with the free end of the output shaft of the rotating motor. Each limit block is provided with a second threaded hole for cooperating with the screw rod. The projection of the limit block in the plane parallel to the second threaded hole is trapezoidal. When the two limit blocks are both located on the screw rod, the small-head ends of the trapezoids of the two limit blocks face each other. A limiter for limiting and fixing the limit blocks is arranged on the screw rod.

[0009] Preferably, the limiter includes a first limit nut. The outer diameter of the screw rod is smaller than the outer diameter of the output shaft of the rotating motor.

[0022] As shown Figures 1-5 in the figure, a device for rectifying the deviation of a demoulding cloth in the production of pultruded plates includes a linear mover. A rotating motor 1 is provided at the execution end of the linear mover. The output shaft of the rotating motor 1 is parallel to the moving direction of the linear mover, and a reel installer is fixedly provided on the output shaft of the rotating motor.

[0023] When producing the pultruded plate 18, the linear mover is fixedly placed on a bracket, and the bracket is installed on one side of the starting end of the production line for the pultruded plate 18. Then, the reel 17 wound with the demoulding cloth 16 is installed on the reel installer. Then, one end of the demoulding cloth 16 on the reel 17 is passed through the mold 14, so that when in the mold 14, the demoulding cloth 16 is located above the pultruded plate 18. Then, a winding roller (not shown in the figure) for winding the demoulding cloth 16 is installed between the terminal of the production line for the pultruded plate 18 and the mold 14. This is the usage of the demoulding cloth 16 in the process of producing the pultruded plate 18. In this embodiment, the axial movement of the rotating motor 1 is controlled by the linear mover, thereby driving the demoulding cloth 16 to move parallel to the length line of the pultruded plate 18 on the horizontal plane, thus realizing the function of rectifying the deviation. The rotating motor 1 realizes the function of slowly releasing the demoulding cloth 16 on the reel 17.

[0024] As a preferred method, the linear mover includes a fixed seat 2, a lead screw 3, and a handle 4. The lead screw 3 is rotatably provided on the fixed seat 2. One end of the lead screw 3 is provided with the handle 4 outside the fixed seat 2. A slider 13 is slidably provided on the fixed seat 2. A threaded hole threadedly connected between the two ends of the lead screw 3 is provided on the slider 13. The rotating motor 1 is fixedly provided outside the fixed seat 2 on the slider 13. The lead screw 3 is parallel to the output shaft of the rotating motor 1. A plurality of scale lines 12 are arranged on the fixed seat 2 along the axial direction of the lead screw 3. A lead screw rotation limiter is provided on the fixed seat 2. In this way, by providing the lead screw 3, the handle 4, and the fixed seat 2, during the process of rectifying the deviation, the user rotates the handle 4 by hand to realize the rotation of the lead screw 3, and further enables the fixed seat 2 to drive the rotating motor 1 to move along the axial direction of the transmission motor 1, thus realizing the function of linear movement, and thus realizing the rectification of the deviation.

[0025] As a preferred embodiment, the lead screw rotation limiter includes a first screw hole 5 and a bolt 6. The first screw hole 5 is provided on the side wall of the fixed seat 2. The axis of the first screw hole 5 is perpendicular to the upper surface of the fixed seat 2. The lower end of the first screw hole 5 is located directly above the lead screw 3. The length of the bolt 6 is greater than the distance from the upper end of the first screw hole 5 to the lead screw 3. One end of the bolt 6 extends into the first screw hole 5 and is threadedly connected to the first screw hole 5. After such a setting, after the deviation correction is completed, by screwing the bolt 6 into the first screw hole 5, it abuts against the lead screw 3 to prevent the lead screw 3 from moving again after the position of the winding drum 17 is adjusted. When deviation correction is required, the bolt 6 is directly loosened from the first screw hole 5 so that the lower end of the bolt 6 no longer contacts the lead screw 3, and then the lead screw 3 can be rotated by manually rotating the handle 4.

[0026] As a preferred embodiment, the drum installer includes a screw rod 7 and two limit blocks 8. One end of the screw rod 7 is coaxially and fixedly connected to the free end of the output shaft of the rotating motor 1. Each limit block 8 is provided with a second screw hole 15 that cooperates with the screw rod 7. The projection of the limit block 8 in the plane parallel to the second screw hole 15 is trapezoidal. When both limit blocks 8 are located on the screw rod 7, the small-head ends of the trapezoids of the two limit blocks 8 face each other. A limiter for limiting and fixing the limit block 8 is provided on the screw rod 7. After such a setting, the winding drum 17 wound with the demolding cloth 16 is fixed on the screw rod 7 through the two limit blocks 8, thereby realizing the function of fixing the winding drum 17 wound with the demolding cloth 16. The setting of the screw rod 7 facilitates adjusting the distance between the two limit blocks 8, thereby facilitating the function of fixing the demolding cloth 16 with different widths on the screw rod 7; the setting method that the projection of the limit block 8 in the plane parallel to the second screw hole 15 is trapezoidal ensures the coaxiality (concentricity) of the winding drum 17 and the screw rod 7 when the winding drum 17 wound with the demolding cloth 16 is fixed on the screw rod 7, that is, ensures the coaxiality (concentricity) of the winding drum 17 and the output shaft of the rotating motor 1, so as to ensure the uniform speed of the rotating motor 1 releasing the demolding cloth 16.

[0027] As a preferred embodiment, as Figure 1 shown, the limiter includes a first limit nut 9. The outer diameter of the screw rod 7 is smaller than the outer diameter of the output shaft of the rotating motor 1. When both limit blocks 8 and the first limit nut 9 are located on the screw rod 7, the first limit nut 9 is located on the side of the two limit blocks 8 facing away from the rotating motor 1. After such a setting, the output shaft of the rotating motor 1 plays a limiting role, so that only one first limit nut 9 is needed to limit the position of the winding drum 17 on the screw rod 7, thereby preventing the winding drum 7 from moving axially on the screw rod 7.

[0028] As a preferred embodiment, the stopper includes a fixing nut 10 and a second limiting nut 11. The fixing nut 10 is coaxially and fixedly provided at one end of the screw rod 7 facing the rotating motor 1. The outer diameter of the second limiting nut 11 is larger than the outer diameter of the screw rod 7. When the two limiting blocks 8 and the second limiting nut 11 are both located on the screw rod 7, the limiting block 8 is located on the side of the fixing nut 10 facing away from the rotating motor 1, and the second limiting nut 11 is located on the side of the two limiting blocks 8 facing away from the fixing nut 10. After such a setting, the drum 17 is fixed on the screw rod 7 by a fixing nut 10 and a second limiting nut 11, and this design method does not need to consider the size relationship between the outer diameter of the screw rod 7 and the outer diameter of the output shaft of the rotating motor 1.

[0029] As a preferred embodiment, as Figure 2 shown, the outer diameter of the screw rod 7 is greater than or equal to the outer diameter of the output shaft of the rotating motor 1.
