Description

Technical Field

[0001] This utility model relates to the field of glass fiberboard production technology, and specifically to an edge grinding device for glass fiberboard. Background Technology

[0002] Fiberglass boards are formed by laminating prepreg sheets according to certain requirements. After lamination, they are cut to predetermined dimensions to form regularly sized boards. The edges of the cut fiberglass boards are prone to burrs, which can easily cut workers' hands during handling and stacking. Therefore, the edges need to be sanded.

[0003] In the existing technology, there are two main methods for grinding the edges of fiberglass boards: one is for workers to use electric angle grinders and belt sanders to complete the grinding work, which has the disadvantage of high labor intensity and the dust generated affecting the health of workers; the other is to use a robotic arm in conjunction with an electric grinding head to grind the edges. This method has a higher degree of automation, but the purchase cost of the robotic arm is also relatively high. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an edge grinding device for fiberglass boards that can automatically complete the burr grinding process on the edges of fiberglass boards at a relatively low cost.

[0005] The technical solution of this utility model is:

[0006] An edge grinding device for fiberglass boards, comprising:

[0007] The frame has a horizontal worktable fixed in the middle and a crossbeam on top;

[0008] The roller assembly is installed on the top surface of the workbench and conveys the fiberglass board in the front-to-back direction under the drive of the power mechanism.

[0009] The pressure plate assembly has a liftable support, and at least one roller is provided at the bottom of the support for pressing against the top surface of the fiberglass board;

[0010] Two grinding components, mounted on a crossbeam on the left and right sides of the fiberglass board, have motor-driven flexible grinding heads that contact the edges of the fiberglass board.

[0011] In a further embodiment, the pressure plate assembly includes a cylinder fixed to a crossbeam, with the cylinder's push rod suspended downwards and connected to the bracket. When the push rod moves, it drives the bracket to move up and down.

[0012] In a further embodiment, the grinding assembly includes a boom connected to a crossbeam, and the motor is fixed to the lower end of the boom.

[0013] In a further embodiment, the upper end of the boom is connected to the slider, a horizontally arranged guide rail is fixed on the crossbeam, the slider is fitted on the guide rail, and a locking screw for locking the position is installed on the slider.

[0014] In a further embodiment, the lower end of the flexible grinding head extends into the gap between the two rollers.

[0015] Compared with the prior art, this utility model has the following advantages: (1) This utility model uses roller group to transport glass fiber board, and the edge of glass fiber board is polished by two polishing components, which can remove burrs, eliminate the need for manual polishing, and reduce costs; (2) During polishing, the pressure plate component can apply pressure to the glass fiber board to prevent it from jumping, but does not affect its movement; (3) The spacing of the polishing components can be adjusted left and right to adapt to glass fiber boards of different specifications.

[0018] To enable those skilled in the art to more clearly understand the purpose, technical solution and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments, but the present utility model is not limited to the following embodiments.

[0019] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] like Figure 1 As shown, this embodiment provides an edge grinding device for fiberglass boards, including a frame-type frame 1, a horizontal worktable 2 fixed in the middle of the frame 1, and at least one crossbeam 3 on the top of the frame 1. A roller group 4 arranged in the front-back direction is installed on the top surface of the worktable 2. The roller group 4 is a powered roller group 4, which conveys fiberglass boards 5 in the front-back direction under the drive of a power mechanism.

[0021] A pressure plate assembly is provided below the crossbeam 3. This assembly includes a cylinder 13 fixed to the crossbeam 3. The push rod of the cylinder 13 is suspended downwards and connected to a horizontally arranged support 14. When the push rod moves, it drives the support 14 to move up and down. At least one roller 15 is provided at the bottom of the support 14 for pressing against the top surface of the fiberglass board 5. The rotation direction of the roller 15 is the same as that of the roller drum. Generally, the pressure plate assembly is located in the middle of the crossbeam 3.

[0022] Below the crossbeam 3, two grinding assemblies are located on the left and right sides of the fiberglass board 5. Each grinding assembly includes a boom 9 connected to the crossbeam 3. The lower end of the boom 9 is fixed to a motor 7 via a mounting plate 8. The output shaft of the motor is suspended and fixed with a flexible grinding head 6, which is used to contact the edge of the fiberglass board 5. The flexible grinding head 6 can accommodate positional deviations of the fiberglass board 5 within a certain range and is less prone to over-grinding. The flexible grinding head 6 is commercially available.

[0023] Since the fiberglass boards 5 come in various sizes, to improve adaptability, in this embodiment, the upper end of the boom 9 is connected to the slider 11, and a horizontally arranged guide rail 10 is fixed to the bottom of the crossbeam 3. The slider 11 is fitted onto the guide rail 10, and a locking screw 12 for locking the position is installed on the slider 11. The slider 11 can move along the guide rail 10 with the boom 9, motor 7, and grinding head, adjusting the distance between the two flexible grinding heads 6 to accommodate fiberglass boards 5 of different specifications.

[0024] In this embodiment, the lower end of the flexible grinding head 6 extends into the gap between the two rollers, ensuring that the bottom edge of the fiberglass board 5 is also ground, leaving no dead corners. The roller length is determined according to the thickness of the fiberglass board 5.

[0025] In this embodiment, when the fiberglass board 5 is conveyed on the roller assembly 4, it can be maintained in its posture using guide grooves and other guiding components, so that both the left and right edges of the fiberglass board 5 can contact the flexible grinding head 6 on the corresponding sides. This type of guiding structure is prior art and will not be described in detail here.

[0026] The working principle of this embodiment is as follows: the roller assembly 4 drives the fiberglass board 5 forward. When it reaches a predetermined position (which can be determined by a sensor), the cylinder 13 of the pressure plate assembly extends, and the roller 15 presses down onto the top surface of the fiberglass board 5. The applied pressure can be determined as needed. The flexible grinding head 6, driven by the motor 7, grinds the edges of the fiberglass board 5 along its path. After grinding is completed, the pressure plate assembly rises, waiting for the next fiberglass board 5.

[0027] In this embodiment, two edges can be sanded at once, and the sanding of all four edges of the fiberglass board 5 can be completed in two steps.

[0028] The above description is merely a preferred embodiment of this utility model. For those skilled in the art, various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
