The automatic production device for glass fiber reinforced plastic grating comprises a curing unit 1 , a longitudinal winding unit 2 , a transverse winding unit 3 and a traction assembly 4 .

[0028] It should be noted that the preset trajectory refers to the trajectory of the yarn moving according to the appearance of the standard fiberglass grating. The first yarn winding column 21 and the second yarn winding column 32 are respectively located at the yarn turning points. The yarn is wound on the first yarn winding column 21 and the second yarn winding column 32 according to the trajectory, and the obtained yarn product has the same appearance as the standard fiberglass grating.

[0029] For specific implementation, see Figure 1 ,The solid arrow in the figure refers to the horizontal direction, and the dotted arrow refers to the vertical direction.

[0030] It should be noted that the curing medium is a resin, such as a two-component epoxy resin.

[0031] In specific implementation, the first winding cylinders 21 on both sides can move closer to or farther from each other in the longitudinal direction, and the first winding cylinder 21 and the second winding cylinder 32 are raised and lowered synchronously to ensure that the shape of the yarn does not change when the yarn moves as a whole. The axis of the first winding cylinder 21 and the axis of the second winding cylinder 31 are parallel to each other and parallel to the vertical direction respectively.

[0032] Compared with the prior art, the present embodiment provides an automated production system, in which the longitudinal winding unit 2 and the transverse winding unit 3 are in specific positions, and the traction head 41 drives the yarn to automatically wind it along a set trajectory around the first winding column 21 and the second winding column. After the yarn winding is completed, the first winding column 21 and the second winding column 31 drive the yarn into the solidification space, and solidify the yarn with the help of a solidifying medium; the entire production process has a low degree of manual participation, and the overall mechanized and automated production greatly reduces the labor intensity of employees, improves production efficiency, and shortens the overall production cycle; with the help of the first winding column 21 and the second winding column 31 to fix the shape of the yarn, the produced fiberglass grating is of good quality, the fiberglass gratings produced in batches have the same shape and stable quality, and there will be no situation where multiple fiberglass gratings have different sizes, thereby improving the yield rate.

[0033] In some embodiments, the first yarn winding column 21 is provided with a first receiving groove along its circumference, and the second yarn winding column 31 is provided with a second receiving groove along its circumference, and the first receiving groove and the second receiving groove are respectively used to receive the yarn, and the relative heights of the first receiving groove and the second receiving groove are the same. The provision of the first receiving groove and the second receiving groove can fix the position of the yarn when the yarn passes around the first yarn winding column 21 and the second yarn winding column 31, guide the position of the yarn when it slides, and prevent the yarn from falling off the first yarn winding column 21 or the second yarn winding column 31 when moving, thereby improving the stability and quality of the yarn winding.

[0034] In a specific implementation, the first accommodating groove and the second accommodating groove are both thread grooves, and the yarn moves along the threads of the thread grooves.

[0035] As another embodiment of the first accommodating groove and the second accommodating groove, the first accommodating groove and the second accommodating groove are annular grooves, a plurality of first accommodating grooves are provided, and a plurality of first accommodating grooves are spaced apart in the up-and-down direction.

[0036] In some embodiments, see Figure 3 The longitudinal winding unit 2 further includes two first telescopic frames 22, which are arranged on both sides of the curing unit 1 in the longitudinal direction. The top of the first telescopic frame 22 has a first lifting end that can be raised and lowered, and the first lifting end is provided with a guide rail 23 extending in the transverse direction. A plurality of first winding columns 21 are arranged on the corresponding guide rails 23 at intervals, and can move laterally along the corresponding guide rails 23. The first telescopic frame 22 can stably drive the first winding column 21 to move up and down, and then drive the wound yarn to enter the curing space for curing, thereby improving the flexibility of use. The setting of the guide rail 23 makes the distance between two adjacent first winding columns 21 adjustable, thereby increasing the flexibility of use.

[0037] In specific implementation, the first telescopic frame 22 includes a support frame and a plurality of lifting members, the plurality of lifting members are arranged on the top of the support frame at intervals along the lateral direction, the tops of the plurality of lifting members are respectively connected to the bottom of the guide rail 23, and the plurality of lifting members rise and fall synchronously.

[0038] As another embodiment of the first telescopic frame 22, the first telescopic frame includes a support frame and a cylinder. Multiple cylinders are arranged at the bottom of the support frame along the up and down directions. The top of the support frame is connected to the guide rail 23. By controlling the extension distance of the piston rod of the cylinder, the top height of the first telescopic frame 22 is controlled.

[0039] In some embodiments, see Figure 1 and Figure 2 The guide rail 23 is also provided with a telescopic drive member 24, which is provided with a telescopic end that can be telescopic in the longitudinal direction. The first winding column 21 is provided on the corresponding telescopic end, and the telescopic end can drive the first winding column 21 to move longitudinally or transversely above the curing space. The telescopic drive member 24 is a cylinder or a telescopic motor, and the telescopic drive member 24 is provided on the guide rail 23. The telescopic end of the telescopic drive member 24 is telescopic in the longitudinal direction, driving the first winding columns 21 on both sides of the curing unit 1 to move closer to or away from each other. The provision of the telescopic drive member 24 simplifies the difficulty of operating the first winding column 21, the movement mode is simple and reliable, the manufacturing cost of the device is saved, and the movement control accuracy of the first winding column 21 is improved.

[0040] In some embodiments, see Figure 2 The transverse winding unit 3 further includes two second telescopic frames 32, which are arranged on opposite sides of the curing unit 1 in the transverse direction. The top of the second telescopic frame 32 has a second lifting end that can be raised and lowered, and a plurality of second winding cylinders 31 are arranged at intervals on the top of the corresponding second lifting ends. The second telescopic frame 32 supports a plurality of second winding cylinders 31 and drives the plurality of second winding cylinders 31 to rise and fall to complete the winding and curing steps. The second telescopic frame 32 can move up and down, which improves the flexibility of use. At the same time, it cooperates with the movement and lifting of the first winding cylinder 21 to ensure that the yarn will not be deformed or tilted when it is lifted and lowered, thereby ensuring the quality of curing.

[0041] In some embodiments, see Figure 1 The FRP grating automated production device further includes a closed housing 5, a sealed space is formed inside the closed housing 5, and the curing unit 1, the traction head 41, the plurality of first winding columns 21 and the plurality of second winding columns 31 are all in the sealed space. The closed housing 5 can provide a sealed space to prevent the environment from affecting the movement and molding of the yarn, avoid the influence of the environment, and ensure the molding quality of the FRP grating. The closed housing 5 can also block the curing medium in the curing space to prevent the harmful substances in the curing medium from volatilizing and affecting the health of employees.

[0042] In some embodiments, see Figure 3 The traction assembly 4 further includes a transmission rod 42 and a moving member 43. The moving member 43 can drive the transmission rod 42 to move in the longitudinal, transverse and up and down directions respectively. The transmission rod 42 includes a horizontal rod and a vertical rod connected to each other in an L shape. A traction head 41 is provided on the top of the vertical rod, and one end of the horizontal rod is connected to the moving member 43. The transmission rod 42 connects the moving member 43 and the traction head 41. The transmission rod 42 facilitates the movement of the traction head 41. The moving member 43 is away from the top of the curing space, which reduces the difficulty of installation and facilitates the overall assembly of the device. The transmission rod 42 is small in size, has a large moving space, and is flexible to use.

[0043] Based on the same inventive concept, refer to Figures 4 to 7 The present application also provides a glass fiber reinforced plastic grating production process, which is implemented based on the glass fiber reinforced plastic grating automated production device as in any one of the above embodiments, and the glass fiber reinforced plastic grating production process includes the following steps: S1: operating the multiple first winding posts 21 in the two longitudinal yarn groups 2 to approach each other in the longitudinal direction; S2: the traction head 41 drives the yarn to shuttle through the multiple first winding posts 21 in the transverse direction in a snake-like manner; S3: operating the multiple first winding posts 21 in the two longitudinal yarn groups 2 to move away from each other in the longitudinal direction, and adjusting the relative distance between the multiple first winding posts 21 so that the yarn is toothed shaped to form a longitudinal yarn layer; S4: the traction head 41 continues to drive the same yarn to snake-like wind a plurality of second winding columns 31 longitudinally to form a transverse yarn layer, and the longitudinal yarn layer and the transverse yarn layer cooperate to form a layer of yarn grid; S5: the traction head 41 drives the same yarn to move downward a specified distance, and repeats steps S2 and S4 to wind the yarn into a plurality of yarn grids stacked in the up and down directions; S6: the first winding column 21 and the second winding column 31 descend, so that the plurality of yarn grids enter the curing space for curing, and obtain the fiberglass grille.

[0044] It should be noted that, see Figure 5 The relative distance between the multiple first yarn winding cylinders 21 is adjusted in step S3 to arrange the yarn in a toothed shape, which is the same as the yarn layout of the finished product, to facilitate the subsequent winding work, and to avoid adjusting the preset path of the yarn during the winding process. In specific implementation, the relative distance between the multiple telescopic driving members 24 on the guide rail 23 is adjusted to divide the two first yarn winding cylinders 21 into a group, and the relative distance between the two adjacent groups is equal to the relative maximum distance between the two first yarn winding cylinders 21 in the same group.

[0045] It should be noted that during the production of the FRP grating, after the first winding columns 21 move away from each other, they no longer move in the horizontal direction. The traction head 41 drives the yarn to only repeat steps S2 and S4. The yarn first snakes around the first winding column 21 in a horizontal direction, and then snakes around multiple second winding columns 31 in a longitudinal direction.

[0046] Compared with the prior art, the FRP grating production process provided in the present embodiment provides an automated production system, in which the longitudinal winding unit 2 and the transverse winding unit 3 are in specific positions, and the traction head 41 drives the yarn to automatically wind it along a set trajectory around the first winding column 21 and the second winding column 31. After the yarn winding is completed, the first winding column 21 and the second winding column 31 drive the yarn into the curing space, and the yarn is cured with the help of a curing medium; the entire production process has a low degree of manual participation, and the overall mechanized and automated production greatly reduces the labor intensity of employees, improves production efficiency, and shortens the overall production cycle; with the help of the first winding column 21 and the second winding column 31 to fix the shape of the yarn, the produced FRP grating is of good quality, the mass-produced FRP gratings have the same shape and stable quality, and there will be no situation where multiple FRP gratings have different sizes, thereby improving the yield rate. During production, the yarn is repeatedly wound along the first yarn winding column 21 and the second yarn winding column 31, and the first yarn winding column 21 and the second yarn winding column 31 stably guide and position the yarn to ensure that the yarn movement trajectory is regular, thereby improving the structural strength and stable quality of the produced fiberglass reinforced plastic grating; the yarn is first fixed and then cured, so that there is no need to adjust the position of the yarn during the curing process, which simplifies the complexity of the curing step and improves work efficiency.

[0047] In some embodiments, step S6 specifically includes the first winding column 21 and the second winding column 31 descending synchronously, allowing the yarn grid to enter the curing space, pouring resin on the yarn grid in the curing space, making the yarn grid completely impregnated with resin, and controlling the temperature and pressure to cure the yarn layer. The temperature and pressure are controlled to cure the yarn layer, and the yarn layer is first shaped, and then the resin is poured, without considering the problem of shaping while pouring, which reduces the manufacturing difficulty. In specific implementation, the temperature is controlled to be between 80-150°C, and the control time is between 2-4 hours.

[0048] In some embodiments, step S1 specifically includes: defining the first winding column of one of the two first yarn groups as the first column, defining the first winding column of the other of the two first yarn groups as the second column, and multiple first columns and multiple second columns approach each other until the centers of the multiple first columns and the centers of the multiple second columns are located in the same vertical plane, and multiple first columns and multiple second columns are arranged in a staggered manner in the horizontal direction, and the traction head 41 drives the yarn to snake around the first column and the second column in sequence in the horizontal direction. This embodiment provides a preset trajectory of the yarn and a method for winding the yarn. The yarn wound through this preset path has the same structure as the finished product and has high strength, ensuring production quality.

[0049] When it is implemented specifically, refer to the figure. First, the yarn is wound around a first column, then moves longitudinally to bypass two second columns, then moves longitudinally to bypass two first columns, and repeats this process to form a toothed line shape. When winding on the second winding column 31, the yarn is wound from the first column / second column to the second winding column 31, and the yarn moves transversely to the second winding column 31 on the other side. After bypassing two second winding columns 31 on the same side, the yarn is moved transversely to the first side again to be wound around two second winding columns 31, and repeats this process to form a toothed line shape.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
