Description

Technical Field

[0001] This utility model belongs to the field of composite material preparation technology, and relates to a device for preparing composite insulating shell material. Background Technology

[0002] Composite insulating housings are generally used in the petroleum and power industries for instruments requiring insulation and a certain level of strength. They must possess good insulation and sufficiently high strength. In the field of petroleum logging instruments, they are commonly used as outer protective housings for the test probe. These housings are installed outside the test probe to protect it. During use, the composite protective housing is in direct contact with the mud or wellbore. When electrical logging and acoustic logging instruments are lowered or raised, the test probe measures real-time parameters of each formation segment. The composite protective housing must have good insulation to avoid affecting the transmission of measurement signals and must withstand tensile and bending forces during use. Composite insulating shells are generally composed of composite fabric reinforced with epoxy resin. The length of composite insulating shells is generally between 1.5 meters and 4.5 meters, and the width of the composite fabric is generally up to 1.27 meters. In conventional methods for producing composite insulating shells longer than 1.27 meters, one method is to cut the composite fabric into strips about 10 centimeters wide, install the strips on a winding machine, and then spirally wind the strips back and forth on the surface of the mold after passing through an impregnation tank until the required thickness is achieved. The shells are then heated and cured. Composite insulating shells produced by this method have low tensile strength, a large coefficient of expansion in the longitudinal direction after heating, and poor product density. Another method is to cut the composite fabric to the required length along its length and lay it manually on the mold surface, overlapping a piece of fabric for each width of the fabric. During the winding process, the tension of the fiber fabric is inconsistent, and resin glue is usually applied with a brush to impregnate the composite fabric until the required thickness is achieved. The disadvantages of this method are: manual fabric laying makes the composite fabric prone to deformation, uneven tension, low degree of mechanization, large impact of human factors on product performance, poor product consistency, and many air holes in the product. Neither of these two methods can meet the requirements of composite insulation shells for high-strength use conditions. Summary of the Invention

[0003] The purpose of this invention is to provide a composite insulating shell material preparation device that avoids the disadvantages of uncontrollable quality in conventional manual operations, has a high degree of mechanization, produces products with high overall strength, and is suitable for mass production.

[0004] The technical solution of this utility model is:

[0005] A composite insulating shell material preparation apparatus includes a fabric roll correction mechanism and a fabric rolling mechanism, with a tensioning mechanism provided between the fabric roll correction mechanism and the fabric rolling mechanism; a fabric rolling motor is provided in the fabric rolling mechanism.

[0006] The fabric roll correction mechanism includes a control cabinet. Inside the control cabinet, multiple layers of interconnected fabric roll shafts are arranged from top to bottom. Each interconnected fabric roll shaft consists of several sub-roll shafts connected by universal joints. Both ends of the interconnected fabric roll shafts are connected to the control cabinet via ball bearing seats. The ball bearing seats serve as the fulcrum for each group of interconnected fabric roll shafts and also provide horizontal angle adjustment. The universal joints provide horizontal angle adjustment, torque transmission, and synchronous rotational speed.

[0007] Composite fabric is placed on the sub-roll fabric shaft. According to the different widths of the composite fabric, it is divided into a first width fabric roll and a second width fabric roll. The first width fabric roll is arranged in several layers from top to bottom, and the overlap seams of two adjacent first width fabric rolls are staggered. The second width fabric roll is placed on both sides of the bottom layer. All the composite fabrics on the sub-roll fabric shaft are gathered into two layers, first connected to the tensioning mechanism, and then passed through the tensioning mechanism into the rolling mechanism to form the final fabric roll.

[0008] All the first-width fabric rolls near the center, due to their staggered overlaps, are guaranteed to converge into two layers in the tensioning mechanism. However, the first-width fabric rolls at the edges cannot guarantee this. But by placing second-width fabric rolls on both sides, the requirement for all materials to form two layers is ensured. Different composite fabrics of different materials and widths can be placed on each sub-roll fabric shaft to meet various combination needs.

[0009] The tensioning mechanism is a device that can control the tension of a composite material fabric to a certain extent and allows it to rotate. The tension control mechanism is not limited to a magnetic powder tension controller.

[0010] Furthermore, a correction infrared monitoring mechanism is installed on the control cabinet.

[0011] Furthermore, the control cabinet is equipped with bearing frames of the same number as the serially connected fabric roll shafts, and each bearing frame is equipped with a linear motor, which is coaxially arranged with the serially connected fabric roll shafts.

[0012] The correction infrared monitoring mechanism is used to monitor whether the fabric roll on the fabric roll shaft has shifted. After sensing the shift of the fabric roll on the connected sub-roll shaft, the linear motor adjusts the fabric roll angle according to the control chip command.

[0013] Furthermore, the fabric rolling mechanism also includes a support box, a linear slide rail at the top of the support box, two sets of bearing seats slidingly arranged in the linear slide rail, two fabric rolling rollers arranged in parallel in the two sets of bearing seats, a butterfly spring between the bearing seat near the tensioning mechanism and the side of the support box; and a pressure roller that can be adjusted up and down is provided directly above the middle position of the two fabric rolling rollers.

[0014] The adjustable pressure roller at the top, along with the butterfly springs and linear guide rails, allows the opening and closing of the pressure roller and the two fabric winding rollers to be adjusted as needed. This design ensures that during the winding process, as the winding diameter changes, the butterfly springs provide pre-pressure. The number of butterfly springs can be adjusted to achieve the effect of pressing the fabric layers together. As the winding thickness of the fabric layer increases, controllable pressure is continuously provided.

[0015] This utility model has the following technical effects:

[0016] This invention utilizes universal joints to connect several sub-roll shafts into a single, longer roll shaft in the fabric winding correction mechanism. This design can accommodate fabrics of varying widths. Furthermore, by employing multi-layered, interconnected roll shafts, it is possible to wind composite fabrics of different specifications, significantly improving winding efficiency. Within the fabric winding mechanism, the combined action of adjustable pressure rollers, disc springs, and linear guides allows the three pressure rollers to adjust their opening and closing angles as needed, adapting to different fabric thicknesses.

[0017] This new type of equipment avoids the disadvantages of uncontrollable quality in conventional manual operation. It has a high degree of mechanization, produces products with high overall strength, and is suitable for mass production. Attached Figure Description

[0025] The fabric roll correction mechanism 1 includes a control cabinet 101. Inside the control cabinet 101, multiple layers of serially connected fabric roll shafts 102 are arranged from top to bottom. Each serially connected fabric roll shaft 102 is composed of several sub-fabric roll shafts 1021 connected by universal joints 1022. Both ends of the serially connected fabric roll shafts 102 are connected to the control cabinet 101 via ball bearing seats 103. The ball bearing seats 103 serve as the fulcrum for each group of serially connected fabric roll shafts 102 and also provide horizontal angle adjustment. The universal joints 1022 provide horizontal angle adjustment, torque transmission, and synchronous rotational speed.

[0026] Composite fabric is provided on the sub-roll fabric shaft 1021. According to the different widths of the composite fabric, it is divided into a first width fabric roll K1 and a second width fabric roll K2. The first width fabric roll K1 is arranged in several layers from top to bottom, and the overlap seams of two adjacent first width fabric rolls K1 are staggered. The second width fabric roll K2 is arranged on both sides of the bottom layer. All the composite fabrics on the sub-roll fabric shaft 1021 are gathered into two layers, first connected to the tensioning mechanism 3, and then passed through the tensioning mechanism 3 into the rolling mechanism 2 to form the final fabric roll.

[0027] All the first width fabric rolls K1 near the middle are guaranteed to converge into two layers in the tensioning mechanism 3 due to the staggered arrangement of their overlaps. However, the first width fabric rolls K1 at the edges cannot be guaranteed to do so. But when the second width fabric rolls K2 are set on both sides, the requirement that all materials form two layers is guaranteed.

[0028] The tensioning mechanism 3 is a device that can control the tension of the composite material fabric to a certain extent and allows it to rotate. The tension control mechanism is not limited to a magnetic powder tension controller.

[0029] The control cabinet 101 is equipped with a correction infrared monitoring mechanism. The control cabinet 101 is also equipped with bearing frames 104 in the same number as the serially connected fabric roll shafts 102. Each bearing frame 104 is equipped with a linear motor 105, which is coaxially arranged with the serially connected fabric roll shafts 102.

[0030] The correction infrared monitoring mechanism is used to monitor whether the fabric roll on the fabric roll shaft has shifted. After sensing the shift of the fabric roll on the connected sub-roll shaft, the linear motor adjusts the fabric roll angle according to the control chip command.

[0031] The fabric rolling mechanism 2 also includes a support box 202. A linear slide rail 203 is provided at the top of the support box 202. Two sets of bearing seats 204 are slidably arranged in the linear slide rail 203. Two fabric rolling rollers 205 are arranged in parallel in the two sets of bearing seats 204. A butterfly spring 206 is provided between the bearing seat 204 near the side of the tensioning mechanism 3 and the side of the support box 202. A pressure roller 207 that can be adjusted up and down is provided directly above the middle position of the two fabric rolling rollers 205.

[0032] The adjustable pressure roller 207 at the top, along with the butterfly spring 206 and the linear guide rail 203, allows the opening and closing of the pressure roller 207 and the two fabric winding rollers 205 to be adjusted as needed. This design ensures that during the winding process, as the winding diameter changes, the butterfly spring 206 provides pre-pressure. The number of butterfly springs 206 can be adjusted to achieve the effect of pressing the fabric layer. As the winding thickness of the fabric layer increases, controllable pressure is continuously provided.
