Description

Technical Field

[0001] This utility model belongs to the technical field of adhesive coating equipment, and specifically relates to a glass fiber adhesive coating equipment. Background Technology

[0002] Fiberglass coating refers to applying an adhesive (such as resin, glue, polymer coating, etc.) to the surface of fiberglass cloth (or fabric) to improve its mechanical properties, adhesion, corrosion resistance, or composite properties with other materials. When using fiberglass coating equipment to coat fiberglass, the tensile coefficient of the fiber is a crucial production reference factor. Due to the low initial tensile strength of fiberglass, it may vibrate or shift during the coating process, resulting in uneven coating thickness. This can reduce the quality of the fiberglass coating and affect the quality of the final product. Furthermore, insufficient tensile strength can cause the fiber to bear greater tensile stress during subsequent processing, increasing the risk of breakage. Therefore, a new structure is proposed to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a glass fiber coating equipment to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a glass fiber coating equipment, comprising: a tension adjustment assembly, wherein the tension adjustment assembly includes a mounting frame for mounting a lifting adjustment roller, and a fixing frame for mounting a fixed roller is provided on the outside of the mounting frame, wherein the fixed roller is located below the lifting adjustment roller;

[0005] The lifting and adjusting roller has several sets of extrusion grooves arranged sequentially from front to back on its curved surface. Adjacent sets of extrusion grooves are separated by a spacer ring. The fixed roller has several sets of extrusion rings arranged sequentially from front to back on its curved surface. Adjacent sets of extrusion rings are connected by a mating groove.

[0006] In a preferred embodiment, the tension adjustment component is installed on the upper right side of the workbench, an unwinding roller is installed on the right side of the tension adjustment component, a glue application box is provided on the left side of the tension adjustment component, and an immersion tank is provided on the right side inside the glue application box.

[0007] The coating box has a feed inlet on the right side and a discharge outlet on the left side. The coating box also has a drying box on the left side for drying glass fibers.

[0008] In a preferred embodiment, an electric push rod is vertically installed at the front and rear positions of the top of the fixed frame. The lower output end of the electric push rod is fixed to the top of the mounting frame via a push rod. A guide column is installed at the center of the top of the fixed frame. When the mounting frame moves up and down, the guide column can ensure the stability of the mounting frame's up and down movement, thereby ensuring the stability of the lifting and adjusting roller's up and down movement, so that several sets of extrusion grooves can accurately align with several sets of extrusion rings on the outer side of the fixed roller.

[0009] In a preferred embodiment, the bottom of the guide column is fixed to the center of the top of the mounting frame, a limiting block is provided at the top of the guide column, and the lower inner side of the mounting frame is connected to the lifting adjustment roller through a rotating shaft.

[0010] In a preferred embodiment, the length of the lifting adjustment roller is the same as the length of the fixed roller, the number of extrusion grooves is the same as the number of extrusion rings, and the width and depth of the extrusion grooves match the width and thickness of the extrusion rings.

[0011] In a preferred embodiment, both the extrusion ring and the extrusion groove are made of flexible rubber, a pressure sensor is installed inside the extrusion ring, and several sets of the extrusion grooves have the same specifications, as do several sets of the extrusion rings.

[0012] In a preferred embodiment, a take-up roller is installed on the left side of the glue-applying box. The rear side of the take-up roller is driven by a motor. The unwinding roller and the take-up roller have the same specifications and are arranged in parallel left and right.

[0013] In a preferred embodiment, the side of the spacer away from the center is arc-shaped, and the spacer is made of stainless steel. When the glass fiber comes into contact with the smooth stainless steel curved surface of the spacer, it will be divided by the curved surface and slide down into the extrusion grooves at the front and rear positions of the spacer. Therefore, by using several sets of spacers, several sets of glass fibers can be divided into the same number of parts as the number of extrusion grooves, which facilitates precise control of the glass fiber tension.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting a tension adjustment component, the tension adjustment component includes a lifting adjustment roller, a fixed roller, and a guide column. The lifting adjustment roller is installed on the lower inner side of the mounting frame. The top of the mounting frame is connected to the lower part of the two sets of electric push rods on the top of the outer fixed frame through two sets of push rods. The fixed roller is installed on the lower inner side of the fixed frame. The fixed roller is located below the lifting adjustment roller. Several sets of extrusion grooves are sequentially opened from front to back on the curved surface of the lifting adjustment roller. Several sets of pressure rings matching the specifications of the extrusion grooves are sequentially arranged from front to back on the curved surface of the fixed roller. The extrusion rings and the extrusion groove material are... The material is flexible rubber. In actual use, the glass fiber passes through the gap between the lifting adjustment roller and the fixed roller. At this time, the lifting adjustment roller moves downward under the action of the electric push rod, and causes several sets of extrusion grooves to move downward to the outside of several sets of extrusion rings, until the glass fiber inside the extrusion groove is squeezed between the extrusion ring and the extrusion groove. As the winding roller winds up, the glass fiber moves to the left. During this process, the tension of the glass fiber can be increased or decreased by adjusting the pressure between the lifting adjustment roller and the fixed roller. Therefore, the tension of the glass fiber during coating can be flexibly adjusted to improve the coating quality.

[0015] 2. By setting extrusion grooves, extrusion rings, and spacers, the extrusion grooves and extrusion rings are made of flexible rubber, while the spacers are made of stainless steel. The number of extrusion grooves is the same as the number of extrusion rings, and their positions are vertically opposite. The side of the spacers away from the center has an arc-shaped structure. During use, when the pressure between the extrusion grooves and extrusion rings is zero, several groups of glass fibers are located between the lifting adjustment roller and the fixed roller. As the lifting adjustment roller gradually moves closer to the fixed roller, the several groups of glass fibers are divided into several groups by the arc-shaped surfaces of the spacers and laid flat inside the extrusion grooves. Therefore, the final effect is that by setting several groups of spacers, several groups of glass fibers can be divided into several parts and laid flat inside the extrusion grooves, thereby improving the accuracy of glass fiber tension control.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only one aspect of the present utility model, and not all aspects. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 5 A glass fiber coating device includes a tension adjustment assembly 200, which includes a mounting frame 210 for mounting a lifting adjustment roller 220, and a fixing frame for mounting a fixed roller 230 on the outside of the mounting frame 210, with the fixed roller 230 located below the lifting adjustment roller 220.

[0026] The lifting adjustment roller 220 has several sets of extrusion grooves 221 arranged sequentially from front to back on its curved surface. Adjacent sets of extrusion grooves 221 are separated by a spacer ring 222. The fixed roller 230 has several sets of extrusion rings 231 arranged sequentially from front to back on its curved surface. Adjacent sets of extrusion rings 231 are separated by a docking groove 232.

[0027] The tension adjustment component 200 is installed on the upper right side of the workbench 100. The unwinding roller 110 is installed on the right side of the tension adjustment component 200. The glue application box 130 is provided on the left side of the tension adjustment component 200. The immersion tank is provided on the right side inside the glue application box 130.

[0028] The coating box 130 has a feed inlet on the right side and a discharge outlet on the left side. The coating box 130 also has a drying box on the left side for drying glass fibers.

[0029] An electric push rod 250 is vertically installed at the front and rear positions of the top of the fixed frame. The output end of the electric push rod 250 is fixed to the top of the mounting frame 210 through a push rod. A guide column 240 is installed at the center of the top of the fixed frame. When the mounting frame 210 moves up and down, the guide column 240 can ensure the stability of the mounting frame 210's up and down movement, thereby ensuring the stability of the lifting adjustment roller 220's up and down movement, so that several sets of extrusion grooves 221 can accurately align with several sets of extrusion rings 231 on the outside of the fixed roller 230.

[0030] The bottom of the guide column 240 is fixed to the center of the top of the mounting frame 210. A limit block is provided on the top of the guide column 240. The lower inner side of the mounting frame 210 is connected to the lifting adjustment roller 220 through a rotating shaft.

[0031] The length of the lifting adjustment roller 220 is the same as the length of the fixed roller 230, the number of extrusion grooves 221 is the same as the number of extrusion rings 231, and the width and depth of the extrusion grooves 221 match the width and thickness of the extrusion rings 231.

[0032] Both the extrusion ring 231 and the extrusion groove 221 are made of flexible rubber. A pressure sensor is installed inside the extrusion ring 231. Several sets of extrusion grooves 221 have the same specifications, and several sets of extrusion rings 231 have the same specifications.

[0033] A take-up roller 120 is installed on the left side of the glue application box 130. The rear side of the take-up roller 120 is driven by a motor. The unwind roller 110 has the same specifications as the take-up roller 120 and is arranged in parallel left and right.

[0034] The side of the spacer ring 222 away from the center is arc-shaped. The spacer ring 222 is made of stainless steel. When the glass fiber comes into contact with the smooth stainless steel curved surface of the spacer ring 222, it will be divided by the curved surface and slide down into the extrusion groove 221 at the front and rear positions of the spacer ring 222. Therefore, by using a number of spacer rings 222, a number of glass fibers can be divided into the same number of parts as the number of extrusion grooves 221, which facilitates the precise control of the glass fiber tension.

[0035] Example 1: Please refer to Figures 1 to 5In actual use, the tension adjustment assembly 200 includes a fixed frame, a mounting frame 210, a lifting adjustment roller 220, and a fixed roller 230. The fixed frame is installed above the worktable 100, and the mounting frame 210 is located inside the fixed frame. An electric push rod 250 is vertically installed at the front and rear positions of the top of the fixed frame. The output ends of the two sets of electric push rods 250 are fixed to the top of the mounting frame 210 via a push rod. A lifting adjustment roller 220 is installed on the lower inner side of the mounting frame via a rotating shaft. The horizontal height of the lifting adjustment roller 220 is lower than the horizontal height of the bottom of the mounting frame 210. A fixed roller 230 is installed on the lower inner side of the fixed frame, below the lifting adjustment roller 220. Several sets of extrusion grooves 221 are sequentially formed on the curved surface of the lifting adjustment roller 220 from front to back. A stainless steel material is provided between two adjacent sets of extrusion grooves 221. The spacer 222 and the fixed roller 230 have several sets of extrusion rings 231 arranged sequentially from front to back on the curved surface. The extrusion rings 231 are equipped with pressure sensors. A docking groove 232 is opened between two adjacent sets of extrusion rings 231. The number of extrusion rings 231 is the same as the number of extrusion grooves 221, and the width and thickness of the extrusion rings 231 match the width and depth of the extrusion grooves 221. A unwinding roller 110 is installed on the right side of the lifting adjustment component. A coating box 130 is installed on the left side of the lifting adjustment component. A soaking tank is provided on the right side of the coating box 130. A drying box is provided on the left side of the coating box 130 (the coating and drying of glass fiber inside the coating box 130 is existing technology, and its internal structure and working principle will not be described here). A take-up roller 120 is installed on the left side of the coating box 130. The take-up roller 120 is driven to take up by a motor at the rear.

[0036] In actual use, several groups of glass fibers are released from the outside of the unwinding roller 110 and pass to the left between the lifting adjustment roller 220 and the fixed roller 230. At this time, the pressure between the lifting adjustment roller 220 and the fixed roller 230 is zero. Two sets of electric push rods 250 are activated, and the mounting frame 210 is pushed downward along the inner side of the fixed frame through two sets of push rods. This causes the lifting adjustment roller 220 to gradually move downward and approach the fixed roller 230 until several groups of extrusion grooves 221 move to the outside of the extrusion grooves 221. As the lifting adjustment roller 220 continues to descend, several groups of glass fibers inside the extrusion grooves 221 are gradually squeezed between the upper surface of the inner side of the extrusion grooves 221 and the upper surface of the extrusion ring 231. The tension change of the glass fibers can be monitored in real time by the pressure sensor. Therefore, by controlling the up and down movement of the lifting adjustment roller 220, the pressure between the extrusion ring 231 and the extrusion groove 221 can be controlled, thereby controlling the tension of the glass fibers. This greatly improves the quality of glass fiber coating.

[0037] Example 2: Please refer to Figures 3 to 5The extrusion ring 231 and the extrusion groove 221 are both made of flexible rubber to prevent damage to the glass fiber when they are squeezed together. The spacer ring 222 is made of stainless steel and has an arc-shaped structure on the side away from the center. When the bottom of the lifting adjustment roller 220 gradually approaches the top of the fixed roller 230, several groups of glass fibers gathered together come into contact with and are divided by several groups of spacers 222. Since the side of the spacer ring 222 away from the center is arc-shaped, the glass fibers are divided when they come into contact with the arc surface and slide along the arc surface of the spacer ring 222 into the extrusion groove 221 on the front and back sides of the spacer ring 222. Therefore, several groups of glass fibers are divided into the same number of parts as the number of extrusion grooves 221 by several groups of spacers 222 and are laid flat on the inner upper surface of the extrusion groove 221. Therefore, the final effect is that several groups of glass fibers can be divided into the same number of parts as the number of extrusion grooves 221, thereby improving the accuracy of glass fiber tension control and thus improving the quality of glass fiber coating.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
