Description

Technical Field

[0001] This utility model belongs to the technical field of gypsum board production equipment, and specifically relates to a fiberglass wire feeding device for a gypsum board forming machine. Background Technology

[0002] Gypsum board, as a lightweight, high-strength, and fire-resistant building material, is widely used in modern architectural decoration. Its excellent physical properties and ease of processing make it a preferred material for various applications such as interior partitions, ceilings, and walls. To ensure the strength and stability of gypsum board in practical applications, especially in situations with special structural strength requirements, introducing fiberglass strands to enhance its mechanical properties has become a common production process. The addition of fiberglass strands not only significantly improves the flexural strength and impact resistance of gypsum board but also effectively prevents cracking or deformation during long-term use.

[0003] However, traditional gypsum board production equipment was not designed with the need for fiberglass thread introduction in mind, resulting in a lack of efficient and convenient fiberglass thread feeding devices in actual production. This situation not only limits the widespread application of fiberglass thread in gypsum board production but also hinders further improvements in the performance and quality of gypsum boards.

[0004] To address this situation, patent CN211640423U proposes a fiberglass wire feeding device for gypsum board molding machines. This device, through a combination of a wire feeding bracket and an inlet bracket, achieves automatic feeding and uniform distribution of fiberglass wire into the gypsum board slurry. The inlet bracket ensures that the fiberglass wire is accurately fed into the pressing area of ​​the gypsum board molding machine, while the wire feeding bracket is responsible for stable supply and tension control of the fiberglass wire. This innovative design solves, to a certain extent, the technical challenges of introducing fiberglass wire, providing strong support for the production of fiberglass gypsum board.

[0005] Nevertheless, existing technologies still have some shortcomings. In particular, the device cannot flexibly adjust the spacing between fiberglass threads according to production needs, which to some extent limits the performance optimization and customized production of fiberglass gypsum boards in different application scenarios. For gypsum board products that pursue higher strength and more refined structural designs, flexible adjustment of the fiberglass thread spacing is especially important. Therefore, designing a fiberglass thread feeding device that can overcome the shortcomings of existing technologies and achieve adjustable fiberglass thread spacing has become an urgent technical problem to be solved in the gypsum board production field. Summary of the Invention

[0006] To address the shortcomings of the existing technology, this utility model provides a fiberglass wire feeding device for a gypsum board forming machine to solve the above problems.

[0007] This utility model discloses a fiberglass wire feeding device for a gypsum board forming machine, comprising a gantry frame with a crossbeam. A spool adjustment assembly and a wire ring adjustment assembly are respectively installed at both ends of the crossbeam. Each spool adjustment assembly and wire ring adjustment assembly includes a mechanism box containing a telescopic scissor fork. A slider is installed at each intersection of the telescopic scissor fork. An open groove adapted to the slider is provided on the mechanism box. A lead screw seat is installed on each slider at both ends of the telescopic scissor fork. A bidirectional lead screw connecting the two lead screw seats passes through the mechanism box. A spool shaft is installed at the top of each slider of the spool adjustment assembly, and a wire ring is installed at the bottom of each slider of the wire ring adjustment assembly.

[0008] Furthermore, a turntable is provided at the end of the bidirectional lead screw, an indicator is provided on the turntable, and a scale is provided on the mechanism box.

[0009] Furthermore, the turntable is equipped with a rotating handle.

[0010] Furthermore, a pivot bracket is provided on the crossbeam between the spool adjustment assembly and the ring adjustment assembly. A support pivot parallel to the bidirectional lead screw is mounted on the pivot bracket, and a bearing that cooperates with the support pivot is provided on the pivot bracket.

[0011] Furthermore, the height of the supporting shaft is higher than the top of the bobbin shaft.

[0012] Furthermore, the guide ring is a stainless steel ring.

[0013] Furthermore, the top end of the guide ring is provided with a screw end, which is screwed to the slider.

[0014] Furthermore, a rotating sleeve is provided on the spool shaft, and a supporting step is provided at the bottom of the rotating sleeve.

[0015] Compared with existing technologies, this wire feeding device achieves flexible adjustment of the fiberglass wire spacing through an innovative design of the wire spool and wire ring adjustment components, meeting different production needs and improving the performance and customization capabilities of fiberglass gypsum board. At the same time, the addition of the rotating sleeve simplifies the installation and replacement process of the fiberglass wire spool, thereby improving overall production efficiency and ease of operation.

[0022] To better understand this utility model, the following is in conjunction with... Figures 1 to 5 The embodiments of this utility model will be explained in detail below.

[0023] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all relative to the direction of the text. Figure 1 The directions are based on "front, back, left, right, up, down".

[0024] This utility model discloses a fiberglass wire feeding device for a gypsum board forming machine, comprising a gantry frame 1 installed on the gypsum board forming machine 22. The gantry frame 1 has sufficient strength and stability to ensure the stable operation of the fiberglass wire feeding device on the gypsum board forming machine 22. A crossbeam 2 is provided on the gantry frame 1, which serves as the mounting base for the spool adjustment assembly 3 and the wire ring adjustment assembly 4, ensuring the accuracy and stability of the fiberglass wire feeding 21.

[0025] Both the spool adjustment assembly 3 and the ring adjustment assembly 4 include a mechanism box 5, inside which a telescopic scissor mechanism 6 is installed. A slider 7 is provided at each intersection of the telescopic scissor 6, and the slider 7 can slide within an open groove 8 on the mechanism box 5, thereby enabling the slider 7 to move horizontally. A lead screw nut 9 is respectively provided on the slider 7 at both ends of the telescopic scissor 6. A double-acting lead screw 10 is threaded through the mechanism box 5, with its two ends connected to the two lead screw nut 9s respectively. By rotating the double-acting lead screw 10, the two lead screw nut 9s can be driven to move on the double-acting lead screw 10, thereby driving the telescopic scissor 6 to extend and retract, thus adjusting the distance between the sliders 7.

[0026] Each slider 7 of the spool adjusting assembly 3 is topped with a spool shaft 11 for mounting the spool 20. To ensure smooth rotation of the spool 20, a rotating sleeve 18 is provided on the spool shaft 11. Lubricating oil is applied between the rotating sleeve 18 and the spool shaft 11, and a support step 19 is provided at the bottom of the rotating sleeve 18. The design of the rotating sleeve 18 makes the installation and replacement of the spool 20 more convenient. The operator only needs to place the spool 20 on the support step 19, align its center hole with the rotating sleeve 18, and then rotate the spool 20 to fix it to the spool shaft 11. The support step 19 provides additional support and limits the installation depth of the spool 20.

[0027] Each slider 7 of the wire ring adjusting assembly 4 is equipped with a guide ring 12 at its bottom. The guide ring 12 is used to lead the fiberglass thread 21 out of the spool and guide it into the slurry of the gypsum board molding machine 22. By adjusting the distance between the sliders 7 in the spool adjusting assembly 3 and the wire ring adjusting assembly 4, the spacing of the fiberglass thread 21 can be flexibly adjusted to meet different production needs.

[0028] To facilitate adjustment of the bidirectional lead screw 10, a turntable 13 is provided at its end. An indicator 14 is mounted on the turntable 13, and a scale 15 is mounted on the mechanism box 5. Rotating the turntable 13 drives the bidirectional lead screw 10 to rotate, thereby adjusting the spacing of the sliders 7. Simultaneously, by observing the position of the indicator 14 on the scale 15, the spacing of the sliders 7 can be precisely controlled. Furthermore, a rotating handle is provided on the turntable 13 for convenient rotation by the operator.

[0029] To further improve the stability and guidance of the fiberglass thread 21, a pivot bracket 16 is provided on the crossbeam 2 between the spool adjustment assembly 3 and the guide ring adjustment assembly 4. A support pivot 17 parallel to the bidirectional lead screw 10 is mounted on the pivot bracket 16. A bearing is provided on the support pivot 17 to support and guide the fiberglass thread 21 from the spool to the guide ring 12. The height of the support pivot 17 is higher than the top of the spool pivot 11, ensuring that the fiberglass thread 21 can be smoothly drawn out of the spool, pass around the support pivot 17, and finally pass through the guide ring 12 into the slurry of the gypsum board molding machine 22.

[0030] The guide ring 12 is made of stainless steel, which has excellent properties such as corrosion resistance and wear resistance, ensuring the stability and durability of the fiberglass wire 21 during long-term use. The top of the guide ring 12 is provided with a screw end, which is screwed onto the slider 7, making it easy to fix the guide ring 12 onto the slider 7 and achieving a firm connection between the guide ring 12 and the slider 7.

[0031] The usage and principle of this utility model:

[0032] First, adjust the spacing of the sliders 7 in the spool adjustment assembly 3 and the ring adjustment assembly 4 according to production needs. Precisely control the spacing of the sliders 7 by rotating the turntable 13 and observing the position of the indicator 14 on the scale 15. Then, place the spool 20 on the support step 19 of the rotating sleeve 18, aligning its center hole with the rotating sleeve 18, and rotate the spool 20 to fix it to the spool shaft 11. Next, lead the fiberglass thread 21 from the spool, pass it around the support shaft 17, and finally pass it through the guide ring 12 into the slurry of the gypsum board molding machine 22. By adjusting the tension and position of the fiberglass thread 21, ensure that it is evenly distributed in the gypsum board slurry, thereby producing high-performance fiberglass gypsum board.
