Description

Technical Field

[0001] This invention relates to the field of moisture content detection technology, and more specifically, to an online automatic moisture content measurement device for glass fiber direct yarn products. Background Technology

[0002] Alkali-free glass fiber direct untwisted roving is a reinforcing material made from alkali-free glass fiber. It belongs to the category of alkali-free glass fiber direct yarn and is directly drawn through a spinneret. This product is divided into two categories according to the matching resin: thermosetting and thermoplastic. Thermosetting roving is suitable for unsaturated polyester resin, vinyl ester resin, epoxy resin and polyurethane resin. It is widely used in fiber winding, pultrusion molding, hand lay-up molding and other processes, as well as molding processes such as LFT, GMT and CFRT.

[0003] According to existing technology, in the industrial continuous production process of glass fiber direct yarn, the yarn spools are directly transferred off the production line after being wound and formed. The actual production conditions are complex, which leads to a number of practical operational problems. Traditional moisture content testing relies on manual handling, alignment, and weighing of yarn spools. With the fast pace of production and large volume of yarn spools, manual handling not only involves high labor input, but also reduces weighing accuracy due to inconsistent placement postures and tilting. At the same time, the manual operation mode is difficult to match the continuous testing requirements of the production line. Summary of the Invention

[0004] This invention provides an online automatic moisture content measurement device for glass fiber direct yarn products. It uses a fixed plate, support columns, and rotatable tiles to support the yarn bundle. The tiles flexibly conform to the yarn bundle, reducing interference from abnormal posture on the moisture content measurement results. This drives the gripping mechanism to complete lateral displacement, automatically transferring and placing the yarn bundle to be tested. A weighing device, paired with a matching tray, supports the yarn bundle, reducing swaying deviation during weighing. Moisture content is calculated based on weight data. This solves the problems mentioned in the background art, namely: inconsistent placement posture and tilting can further reduce weighing accuracy, and manual operation is difficult to match the continuous testing requirements of a production line.

[0005] To achieve the above objectives, an online automatic moisture content measuring device for glass fiber direct yarn products includes a vehicle body, multiple yarn spools, and a gripping device. A support frame is fixedly connected to the top of the vehicle body, and the multiple yarn spools are respectively arranged on both sides of the support frame. The gripping device is arranged on one side of the support frame and includes a placement plate located on one side of the yarn spool. Two sliders are fixedly connected to one side of the placement plate, and two moving blocks are slidably connected to the outside of each of the two sliders. A connecting plate is fixedly connected to the end of the two moving blocks at the same height away from the placement plate. Two clamping posts are fixedly connected to the end of the connecting plate near the yarn spool, and four clamping posts are arranged on the outside of the yarn spool. The support frame has a support component at one end near the yarn ball. The support component includes a fixed plate fixedly connected to one side of the support frame. Two support columns are fixedly connected to one end of the fixed plate near the yarn ball. Tiles are rotatably connected to the outside of the two support columns. The yarn ball is disposed outside the two tiles.

[0006] In the above technical solution, two sliding rods are fixedly connected to the ends of the two connecting plates that are close to each other. The two sliding rods that are close to each other are covered with sleeves. Two main cylinders are fixedly connected to one side of the placement plate. A connecting block is fixedly connected to the moving end of each of the two main cylinders. One side of the connecting block is fixedly connected to one side of the connecting plate.

[0007] Secondly, a geared disc is rotatably connected to one side of the placement plate, and a rack is fixedly connected to one end of each of the two connecting plates that are close to each other. The two racks mesh with the outside of the geared disc. Two sliding grooves are opened inside the placement plate, and the inner wall of the sliding groove slides in cooperation with the outside of the connecting block.

[0008] Furthermore, based on the above, the top of the placement plate is provided with a moving device, the moving device including a hanger, the hanger being located directly above the placement plate, two slide rails being fixedly connected inside the hanger, a slide being slidably connected outside the two slide rails, the bottom of the slide being fixedly connected to the top of the placement plate, and two auxiliary cylinders being fixedly connected to the top of the hanger, the moving ends of the two auxiliary cylinders being fixedly connected to the top of the slide.

[0009] Meanwhile, a support rod is fixedly connected to the bottom of the hanger, a pad is fixedly connected to the bottom of the support rod, a weighing device is fixedly connected to the top of the pad, a tray is fixedly connected to the top of the bearing end of the weighing device, the top of the tray is provided with a receiving part, and the shape of the receiving part is adapted to the outer periphery of the yarn ball. A main QR code is affixed to one side of the support frame, a secondary QR code is affixed to the top of the support frame, and a conveyor belt is provided at the bottom of the vehicle body.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: In this online automatic moisture content measurement device for glass fiber direct yarn products, a fixed plate and support column, along with rotatable tiles, provide support for the yarn bundle. The tiles flexibly conform to the yarn bundle, reducing interference from abnormal posture on the moisture content measurement results. A clamping structure is formed by a slider, moving block, connecting plate, and clamping column. The clamping range is adjusted under the transmission action of the main cylinder, rack, and toothed disc. The rack and toothed disc also ensure that the center of each clamping is consistent. The combination structure of the slider and sleeve can constrain the movement trajectory of the components. The moving structure composed of the hanger, slide rail, and auxiliary cylinder drives the entire gripping mechanism to complete the lateral displacement, automatically completing the transfer and placement of the yarn bundle to be tested. The weighing device, along with a matching tray, supports the yarn bundle, reducing swaying deviation during weighing. The moisture content is calculated based on the weight data. Two types of QR code labels are placed on the surface of the equipment to bind product production and testing information, facilitating subsequent quality traceability. Attached Figure Description

[0013] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0014] Inconsistent placement postures and tilting can further reduce weighing accuracy, and manual operation modes are difficult to match the continuous testing requirements of production lines.

[0015] Therefore, in view of the above-mentioned problems, the present invention discloses an online automatic measurement device for the moisture content of glass fiber direct yarn products, with reference to... Figure 1 - Figure 6 As shown, the device includes a vehicle body 1, multiple yarn bundles 3, and a gripping device 6. A support frame 2 is fixedly connected to the top of the vehicle body 1. The multiple yarn bundles 3 are respectively arranged on both sides of the support frame 2. The gripping device 6 is arranged on one side of the support frame 2. The gripping device 6 includes a placement plate 601 located on one side of the yarn bundles 3. Two sliders 602 are fixedly connected to one side of the placement plate 601. Two moving blocks 603 are slidably connected to the outside of the two sliders 602. A connecting plate 604 is fixedly connected to the end of the two moving blocks 603 at the same height away from the placement plate 601. Two clamping posts 605 are fixedly connected to the end of the connecting plate 604 near the yarn bundles 3. The four clamping posts 605 are arranged on the outside of the yarn bundles 3. Multiple sets of clamping columns 605 form a ring-shaped structure to hold the yarn bundle 3, preventing slippage and collision during transportation and protecting the integrity of the fiberglass yarn. A main QR code 4 is attached to one side of the support frame 2, and a secondary QR code 9 is attached to the top of the support frame 2. The combination of the main QR code 4 and the secondary QR code 9 enables the recording of individual product information, which facilitates the collection of production data and quality traceability, and makes it easier for subsequent process review and quality control. A conveyor belt 8 is set at the bottom of the vehicle body 1, which enables continuous material flow and is suitable for online continuous operation mode.

[0016] refer to Figure 5 - Figure 8 As shown, two sliding rods 607 are fixedly connected to the ends of the two connecting plates 604 that are close to each other. The two sliding rods 607 that are close to each other are fitted with sleeves 606 to form a sliding guide structure to constrain the movement trajectory of the connecting plates 604. Two main cylinders 608 are fixedly connected to one side of the placement plate 601. Connecting blocks 609 are fixedly connected to the moving ends of the two main cylinders 608. One side of the connecting block 609 is fixedly connected to one side of the connecting plate 604. The cylinders provide stable power output to realize the automatic opening and closing of the clamping structure and reduce manual intervention. A geared disc 610 is rotatably connected to one side of the placement plate 601. A rack 611 is fixedly connected to the end of each of the two connecting plates 604 that are close to each other. The two racks 611 mesh with the outside of the geared disc 610. Through the synchronous meshing transmission between the geared disc 610 and the racks 611 on both sides, the clamping structures on both sides are symmetrically and synchronously displaced, ensuring that the opening and closing action of the clamping column 605 is coordinated and consistent, avoiding uneven clamping force caused by unilateral offset, and also evenly distributing the clamping force to prevent local pressure damage to the yarn ball 3. Two sliding grooves 612 are opened inside the placement plate 601. The inner wall of the sliding groove 612 slides and the outside of the connecting block 609. The opening of the sliding groove 612 facilitates the sliding of the connecting block 609 inside the placement plate 601.

[0017] refer to Figure 3 As shown, a support component 5 is provided at one end of the support frame 2 near the yarn bundle 3. The support component 5 includes a fixed plate 51 fixedly connected to one side of the support frame 2. Two support columns 52 are fixedly connected at one end of the fixed plate 51 near the yarn bundle 3. Tiles 53 are rotatably connected to the outside of the two support columns 52. The yarn bundle 3 is placed outside the two tiles 53. The rotating tiles 53 provide flexible support for the yarn bundle 3. The tiles 53 can adaptively rotate and fit with the placement and removal of the yarn bundle 3, stably supporting the weight of the yarn bundle 3, thereby maintaining the integrity of the overall structure of the yarn bundle 3.

[0018] refer to Figure 7 As shown, a moving device 7 is provided on the top of the placement plate 601. The moving device 7 includes a hanger 71, which is located directly above the placement plate 601. Two slide rails 72 are fixedly connected inside the hanger 71, and a slide 73 is slidably connected to the outside of the two slide rails 72. The bottom of the slide 73 is fixedly connected to the top of the placement plate 601. The sliding cooperation between the slide rails 72 and the slide 73 ensures that the overall lateral movement is stable. Two auxiliary cylinders 74 are fixedly connected to the top of the hanger 71. The moving ends of the two auxiliary cylinders 74 are fixedly connected to the top of the slide 73. The auxiliary cylinders 74 provide linear driving force to drive the overall directional displacement of the gripping mechanism, reducing manual operation and adapting to the continuous operation rhythm of the production line.

[0019] Refer again Figure 7 As shown, a support rod 75 is fixedly connected to the bottom of the hanger 71, a pad 76 is fixedly connected to the bottom of the support rod 75, a weighing device 77 is fixedly connected to the top of the pad 76, and a tray 78 is fixedly connected to the top of the bearing end of the weighing device 77. The top of the tray 78 is provided with a receiving part, and the shape of the receiving part is adapted to the outer periphery of the yarn ball 3, so that the yarn ball 3 is placed in a regular position, avoiding deviation during the weighing process, reducing the interference of external force factors on the weighing data, and thus ensuring the accuracy of the moisture content measurement results of glass fiber direct yarn.

[0020] Working principle of the invention: During operation, the conveyor belt 8 continuously delivers multiple yarn balls 3 to the vicinity of the support frame 2. Each yarn ball 3 has a main QR code 4 attached to one side of the support frame 2 and a secondary QR code 9 attached to the top. When the yarn ball 3 reaches the designated work station, the scanning system automatically reads the main and secondary QR codes 9, associates the individual information of the yarn ball 3 with the current location, and records it, providing a basis for subsequent quality traceability and data collection.

[0021] The main cylinder 608 extends, pushing the connecting plate 604 towards the yarn bundle 3 via the connecting block 609. The connecting plate 604 drives the two clamping posts 605 to retract synchronously, forming a ring-like structure around the yarn bundle 3. Simultaneously, the gear disc 610 meshes with the double-sided racks 611, ensuring symmetrical and synchronous displacement of the clamping mechanisms on both sides, evenly distributing the clamping force, and preventing localized pressure damage to the yarn bundle 3. The clamping posts 605 maintain stable movement thanks to the guiding structure formed by the slide rod 607 and the sleeve 606.

[0022] While the clamping column 605 embraces the yarn ball 3, the tile 53 supports the yarn ball 3. The tile 53 rotates around the support column 52, adapting to the shape of the yarn ball 3 and bearing the weight of the yarn ball 3. When the clamping column 605 clamps tightly, the yarn ball 3 is lifted away from the tile 53, and the tile 53 rotates back to its original position.

[0023] The auxiliary cylinder 74 pushes the slide 73 to move laterally along the slide rail 72. The bottom of the slide 73 is fixedly connected to the placement plate 601, thereby driving the entire gripping device 6 and the yarn ball 3 to move horizontally above the weighing device 77. The hanger 71, support rod 75 and pad 76 provide support to ensure that there is no shaking during the movement.

[0024] The main cylinder 608 on the lower connecting plate 604 is started, placing the yarn ball 3 on the tray 78. The weighing device 77 reads the wet weight data of the yarn ball 3 in real time, binds it with the yarn ball 3 ID previously scanned and entered, and transmits it to the control system. The control system automatically calculates the moisture content based on the known dry weight of the yarn ball 3 and the measured wet weight. The result is stored in association with the information of the yarn ball 3 and fed back to the production line management system. After weighing is completed, the gripping device 6 clamps the yarn ball 3 again and puts the yarn ball 3 back on the surface of the tile 53 in its original position.
