Description

Technical Field

[0001] The utility model relates to the technical field of polytetrafluoroethylene glass cloth production, and more specifically to a glue feeding device for polytetrafluoroethylene glass cloth production. Background Art

[0002] PTFE glass cloth is made of suspended PTFE emulsion and impregnated with high-performance alkali-free glass fiber cloth. It is a high-performance, multi-purpose new product that meets sampling requirements.

[0003] In the process of producing glass fiber cloth, it is necessary to feed glue to it. The existing glue feeding device feeds glue in a small range, that is, only a straight line of glue is formed on the surface of the glass cloth. In the process of flattening the glue, part of the glue will remain on the glass cloth, and in some positions of the glass cloth, the glue has already flowed out before it is applied. The glue is not replenished in time, resulting in the problem of uneven glue feeding. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model aims to provide a glue feeding device for producing polytetrafluoroethylene glass cloth.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a glue feeding device for polytetrafluoroethylene glass cloth production, comprising a conveying component, a transfer component installed on one side of the top of the conveying component, and two groups of adjustment components symmetrically installed on both sides of the transfer component, and the side wall of each group of adjustment components is installed with a glue feeding component.

[0006] Wherein, the two groups of adjustment components both include a support plate installed on the side wall of the corresponding transfer component, the bottom of the support plate is connected to a connecting plate, and the glue feeding component is installed inside the connecting plate.

[0007] The two groups of glue inlet components both include a mounting seat rotatably connected to the inside of the corresponding connecting plate, a glue inlet pipe is installed inside the mounting seat, and the bottom end of the glue inlet pipe extends to the bottom of the corresponding mounting seat and is connected to a glue inlet head.

[0008] The utility model is further configured as follows: the conveying assembly includes a base and two upright frames symmetrically installed on the top of the base, a plurality of rollers are rotatably connected between the two upright frames, and the plurality of rollers are arranged in sequence from right to left, and the plurality of rollers are alternately arranged in layers.

[0009] The utility model is further configured as follows: a glue storage groove is provided on the top of the base and between the two upright frames, and a plurality of the rotating rollers located at the lower layer are embedded in the glue storage groove.

[0010] By adopting the above technical solution, the glass cloth is continuously wound around the outer wall of the layered roller during transportation, and is tensioned by continuous guidance. After the glass cloth is glued, it passes through multiple rollers, and the multiple rollers cooperate to squeeze and flatten the glue on the surface of the glass cloth, and the excess glue falls into the glue storage tank for collection, avoiding waste.

[0011] The utility model is further configured as follows: the transfer assembly includes a support frame installed on one side of the top of the base, the top of the support frame is arranged in an I-shape, two groups of first electric linear guides are symmetrically and horizontally installed on both sides of the support frame, the two sides of the first electric linear guides that repel each other are respectively slidably connected to the second electric linear guides, and the two support plates are respectively vertically slidably connected to the side walls of the corresponding second electric linear guides.

[0012] The utility model is further configured as follows: a driving gear is arranged on one side of the connecting plate, a driven gear is installed on one end of the rotating shaft close to the driving gear, and a synchronous belt is connected between the driving gear and the driven gear.

[0013] The utility model is further configured as follows: a servo motor is installed inside the two connecting plates, and the output end of the servo motor extends to the outside of the side wall of the connecting plate and is connected to the driving gear.

[0014] By adopting the above technical scheme, during the conveying process of the glass cloth, the glue is coated on the surface of the glass cloth by using the glue feeding pipe and the glue feeding head, and during the coating process, the servo motor drives the driving gear to rotate. Since the driving gear and the driven gear are driven by the synchronous belt, when the driving gear rotates, the synchronous belt transmission can make the driven gear rotate by itself, and when the driven gear rotates, it can drive the rotating shaft and the mounting seat to swing synchronously, and the mounting seat drives the glue feeding pipe and the glue feeding head to swing, so as to adjust the angle of the glue feeding head, and two S-shaped glues can be coated on the surface of the glass cloth by using two sets of glue feeding pipes and glue feeding heads, which greatly improves the coverage area and uniformity of the glue feeding.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] (1) By setting an adjustment component and using a servo motor to provide drive, the rotating shaft and the mounting seat swing synchronously, and the mounting seat drives the glue feeding pipe and the glue feeding head to swing, thereby adjusting the angle of the glue feeding head. By using two sets of glue feeding pipes and glue feeding heads, two S-shaped glues can be coated on the surface of the glass cloth, which greatly improves the coverage area and uniformity of the glue feeding.

[0017] (2) By setting up a glue storage tank and rollers, the glass cloth is continuously wound around the outer wall of the layered rollers during transportation, and is continuously guided to tension the glass cloth. After the glue is fed into the glass cloth, the glass cloth passes through multiple rollers, which cooperate to squeeze and flatten the glue on the surface of the glass cloth, and the excess glue falls into the glue storage tank for collection, thereby avoiding waste.

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0028] See also Figure 1-4 , the utility model provides the following technical solutions:

[0029] For example, see Figure 1The invention discloses a glue feeding device for producing polytetrafluoroethylene glass cloth, comprising a conveying component 1, a transfer component 2 installed on one side of the top of the conveying component 1, and two groups of adjusting components 3 symmetrically installed on both sides of the transfer component 2. The side walls of each group of adjusting components 3 are installed with glue feeding components 4. The conveying component 1 is used to guide and convey the polytetrafluoroethylene glass cloth. During the conveying process of the glass cloth, the transfer component 2 drives the adjusting component 3 and the glue feeding component 4 to move to the top surface of the glass cloth, and the glue feeding component 4 is used to continuously apply glue to the surface of the glass cloth. At the same time, the adjusting component 3 drives the glue feeding component 4 to swing, so that the glue forms an S shape on the surface of the glass cloth, and the two groups of glue feeding components 4 swing at the same time, so that there are two groups of S-shaped glue, which greatly improves the coverage and uniformity of the glue feeding.

[0030] See also Figure 1 and Figure 2 The conveying assembly 1 includes a base 11 and two stands 13 symmetrically installed on the top of the base 11. A plurality of rollers 14 are rotatably connected between the two stands 13, and the plurality of rollers 14 are arranged in sequence from right to left. The plurality of rollers 14 are alternately arranged in layers. During the conveying process, the glass cloth is continuously wound around the outer walls of the layered rollers 14, and is continuously guided, thereby tensioning the glass cloth.

[0031] See also Figure 1 and Figure 2 A glue storage groove 12 is provided at the top of the base 11 and between the two upright frames 13. A plurality of rollers 14 located at the lower layer are embedded in the glue storage groove 12. The transfer component 2, the adjustment component 3 and the glue feeding component 4 are all located before the conveying component 1. That is, the glass cloth is continuously guided and conveyed by the plurality of rollers 14 after the glue is fed. Therefore, the plurality of rollers 14 cooperate to squeeze and flatten the glue on the surface of the glass cloth, and the excess glue falls into the glue storage groove 12 for collection.

[0032] See also Figure 1 and Figure 2 The transfer assembly 2 includes a support frame 21 installed on one side of the top of the base 11. The top of the support frame 21 is set in an I-shape. Two groups of first electric linear guides 22 are symmetrically and horizontally installed on both sides of the support frame 21. The repelling sides of the two first electric linear guides 22 are respectively slidably connected with second electric linear guides 23. The first electric linear guide 22 and the second electric linear guide 23 are both stepper motor linear guide slide modules, that is, the stepper motor is used to drive the slide to slide on the linear guide, and the first electric linear guide 22 uses its own slide to drive the second electric linear guide 23 to slide horizontally, thereby adjusting the horizontal position of the second electric linear guide 23.

[0033] See also Figure 1 and Figure 2The two adjustment components 3 both include support plates 31 mounted on the corresponding second electric linear guide rails 23. The two support plates 31 are respectively vertically slidably connected to the side walls of the corresponding second electric linear guide rails 23. The bottom of the support plates 31 is connected with a connecting plate 32. The glue feeding component 4 is installed inside the connecting plate 32. The second electric linear guide rail 23 drives the corresponding support plate 31 to move up and down in the height direction to adjust the position through its own slide seat, thereby adjusting the height of the connecting plate 32 and the glue feeding component 4, so that the glue feeding component 4 can be close to the glass cloth for glue feeding operation.

[0034] See also Figure 3 and Figure 4 A servo motor 33 is installed inside each of the two connecting plates 32. The output end of the servo motor 33 extends to the outside of the side wall of the connecting plate 32 and is connected to a driving gear 34. A driven gear 36 is installed at one end of the rotating shaft 37 close to the driving gear 34. A synchronous belt 35 is connected between the driving gear 34 and the driven gear 36. The servo motor 33 is used to drive the driving gear 34 to rotate. Since the driving gear 34 and the driven gear 36 are driven by the synchronous belt 35, when the driving gear 34 rotates, the synchronous belt 35 is driven to make the driven gear 36 rotate.

[0035] See also Figure 3 and Figure 4 , the two groups of glue feeding components 4 both include a mounting seat 41 rotatably connected to the inside of the corresponding connecting plate 32, a glue feeding pipe 42 is installed inside the mounting seat 41, the bottom end of the glue feeding pipe 42 extends to the bottom of the corresponding mounting seat 41 and is connected to a glue feeding head 43, the two connecting plates 32 are both rotatably connected to the inside of the rotating shaft 37, the side wall of the mounting seat 41 is sleeved and connected to the outer wall of the rotating shaft 37, and both ends of the rotating shaft 37 extend to both sides of the corresponding connecting plate 32, when the driven gear 36 rotates, the rotating shaft 37 and the mounting seat 41 can be driven to swing synchronously, the mounting seat 41 drives the glue feeding pipe 42 and the glue feeding head 43 to swing, so as to adjust the angle of the glue feeding head 43, and two S-shaped glues can be coated on the surface of the glass cloth by using the two groups of glue feeding pipes 42 and the glue feeding head 43, which greatly improves the coverage area and uniformity of the glue feeding.

[0036] Specifically, the staff first connects the glue outlet of the external glue feeding device with the glue inlet pipe 42, and then continuously winds the glass cloth around the outer wall of the layered roller 14, thereby tensioning the glass cloth through continuous guiding.

[0037] During the conveying process of the glass cloth, the glue is applied on the surface of the glass cloth by the glue feeding pipe 42 and the glue feeding head 43, and during the coating process, the servo motor 33 drives the driving gear 34 to rotate. Since the driving gear 34 and the driven gear 36 are driven by the synchronous belt 35, when the driving gear 34 rotates, the synchronous belt 35 drives, so that the driven gear 36 can rotate. When the driven gear 36 rotates, it can drive the rotating shaft 37 and the mounting seat 41 to swing synchronously. The mounting seat 41 drives the glue feeding pipe 42 and the glue feeding head 43 to swing, so as to adjust the angle of the glue feeding head 43. By using two sets of glue feeding pipes 42 and the glue feeding head 43, two S-shaped glues can be applied on the surface of the glass cloth, which greatly improves the coverage area and uniformity of the glue feeding.

[0038] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
