Description

Technical Field

[0001] This utility model belongs to the field of fiberglass septic tank production, and in particular relates to a winding device for processing fiberglass septic tanks. Background Technology

[0002] Fiberglass septic tanks are devices specifically designed for treating domestic sewage, made of synthetic resin as the matrix and glass fiber as the reinforcing material. They are small-scale environmental protection facilities used to treat and purify feces in domestic sewage. Their core function is to achieve preliminary sedimentation, fermentation and decomposition, and water filtration of sewage.

[0003] Fiberglass septic tanks are produced using mechanical winding or hand lay-up processes to form seamless cylindrical or square tanks. Currently, in the initial stages of fiberglass septic tank winding production, manual labor is required to hold the ends of the fiberglass yarn and press them onto the surface of a mold coated with a release agent to "fix the beginnings." This operation has significant drawbacks: firstly, manual labor involves repeatedly adjusting the pressing position around the mold, which is cumbersome and time-consuming, especially for large-diameter molds; secondly, the pressure applied manually is difficult to control precisely, resulting in poor adhesion. When the winding trolley starts pulling the fibers later, the fixed fiber ends are prone to loosening or even falling off, requiring rework. This not only affects production efficiency but may also lead to fiber accumulation on the mold surface due to repeated operations, impacting product surface quality.

[0004] Therefore, there is an urgent need to develop a winding device for processing fiberglass septic tanks that can fix the ends of the fiberglass yarn and compress it during the winding process. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the present invention provides a winding device for processing fiberglass septic tanks, which can fix the ends of fiberglass yarn and compress it during the winding process.

[0006] A winding device for processing fiberglass septic tanks includes a mounting frame, a winding assembly, a film feeding assembly, and a fixed mold assembly. The winding assembly is located at the rear of the mounting frame and can be used to wind molds of different lengths. The winding assembly drives the mold to rotate and wind. The film feeding assembly is located on the mounting frame in front of the winding assembly and has a coating function. During the material feeding process, the film feeding assembly coats the fiberglass yarn with a coating. The fixed mold assembly is installed behind the winding assembly, and its rear end rests on the mold fixed by the winding assembly to fix and compress the wound fiberglass yarn.

[0007] In a preferred embodiment of this utility model, the winding assembly includes a first electric track, a sliding frame, a Y-shaped frame, support wheels, a rotary motor, a connector, fastening bolts, and a mold body.

The first steering roller is rotatably mounted on the front of the movable frame. The support roller is rotatably mounted on the mounting frame behind the first steering roller. The lower pressure roller is rotatably mounted on the movable frame behind the support roller. The bottom of the lower pressure roller is lower than the bottom of the support roller. The storage frame is fixedly mounted on the movable frame at the lower pressure roller by bolts. The bottom of the lower pressure roller is inside the storage frame. The storage frame is used to store adhesive. The second steering roller is provided on the upper rear side of the movable frame. A roll of glass fiber yarn is placed on the feeding roller and then passes around the first steering roller, the support roller, the lower pressure roller, and the second steering roller in sequence.

[0009] In a preferred embodiment of the present invention, the fixed mold assembly includes a telescopic cylinder, an elastic frame, and a pressing roller. The telescopic cylinder is provided at the lower rear side of the movable frame, with the telescopic end of the telescopic cylinder facing the mold body. The telescopic end of the telescopic cylinder is connected to the elastic frame, which can elastically extend and retract back and forth.

The glass fiber yarn passes around the lower pressure roller and then passes between the squeezing roller and the scraping plate.

[0011] Compared with the prior art, this utility model has the following advantages: This utility model controls the extension of the telescopic cylinder to drive the pressing roller to move backward and press it onto the mold body, and fixes the ends of the glass fiber yarn between them. When the glass fiber yarn is wound, the ends do not need to be manually fixed, which facilitates the work. The glass fiber yarn under the lower pressing roller is immersed in adhesive. When the glass fiber yarn is wound, the adhesive can be automatically applied, which improves the automation level of the equipment. The scraper will scrape off the excess adhesive on the glass fiber yarn and spread the adhesive evenly at the same time. Attached Figure Description

The output shaft of the rotary motor 25 is connected to the connector 26. The mold body 28 is placed between the connector 26 and the support wheel 24. The left end of the mold body 28 is inserted into the connector 26 and fixed by fastening bolts 27. The rotary motor 25 can drive the mold body 28 to rotate.

[0022] like Figure 3 and Figure 4As shown, the film feeding assembly 3 includes a second electric track 31, a moving frame 31a, a feeding roller 32, a first steering roller 33, a support roller 34, a lower pressure roller 35, a second steering roller 36, and a storage frame 37. The second electric track 31 is fixedly mounted on the front of the mounting frame 1 by bolts extending laterally. The moving frame 31a is fixedly connected to the slider of the second electric track 31 by bolts. The feeding roller 32 is rotatably mounted on the upper part of the moving frame 31a. The first steering roller 33 is rotatably mounted on the front of the moving frame 31a. A support roller 34 is rotatably mounted on the mounting frame 1 behind the first steering roller 33. A support roller 34 is provided, and a lower pressure roller 35 is rotatably mounted on a movable frame 31a on the rear side of the support roller 34. The bottom of the lower pressure roller 35 is lower than the bottom of the support roller 34. A storage frame 37 is fixedly provided on the movable frame 31a at the lower pressure roller 35 by bolts. The bottom of the lower pressure roller 35 is inside the storage frame 37, which is used to store adhesive. A second steering roller 36 is provided on the upper rear side of the movable frame 31a. A roll of glass fiber yarn is placed on a feeding roller 32 and then passes around the first steering roller 33, the support roller 34, the lower pressure roller 35, and the second steering roller 36 in sequence.

[0023] like Figure 6 As shown, the fixed mold assembly 5 includes a telescopic cylinder 51, an elastic frame 52, and a pressure roller 53. The telescopic cylinder 51 is provided on the lower rear side of the movable frame 31a. The telescopic end of the telescopic cylinder 51 faces the mold body 28. The telescopic end of the telescopic cylinder 51 is connected to the elastic frame 52. The elastic frame 52 can elastically extend and retract back and forth. The pressure roller 53 is rotatably provided at the rear end of the elastic frame 52. The pressure roller 53 is in contact with the surface of the mold body 28.

[0024] In use: First, add adhesive into the storage box 37. Place the rolled glass fiber yarn on the feeding roller 32, and then pass it sequentially around the first steering roller 33, support roller 34, lower pressure roller 35, and second steering roller 36. Then, control the telescopic cylinder 51 to shorten, causing the pressure roller 53 to disengage from the mold body 28. Next, place the end of the glass fiber yarn between the pressure roller 53 and the mold body 28, and control the telescopic cylinder 51 to extend, causing the pressure roller 53 to move backward and press against the mold body 28, thus fixing the end of the glass fiber yarn between them. In this way, the end does not need to be manually fixed during the winding of the glass fiber yarn, which facilitates the work. The glass fiber yarn below the lower pressure roller 35 is soaked in adhesive, and the adhesive can be automatically applied during the winding of the glass fiber yarn. The coating process improves the automation level of the equipment. Then, the control motor 25 starts working, driving the connector 26 to rotate clockwise, which in turn drives the mold body 28 to rotate. During the rotation of the mold body 28, the glass fiber yarn is wound around the mold body 28 for shaping. During the winding of the glass fiber yarn, the second electric track 31 drives the moving frame 31a and its components to move left and right, so that the glass fiber yarn is evenly wound on the mold body 28. After the glass fiber yarn is wound, the control equipment stops working and resets. Then, the fastening bolt 27 is unscrewed. Then, the first electric track 21 drives the moving frame 31a and its components to move to the right a certain distance, so that the mold body 28 is separated from the connector 26. Then, the mold body 28 is disassembled.

[0025] like Figure 5 As shown, it also includes a scraper assembly 4, which is located above and behind the lower pressure roller 35. The scraper assembly 4 includes a pressing roller 41 and a scraper plate 42. The pressing roller 41 is rotatably mounted above and behind the lower pressure roller 35. The scraper plate 42 is rotatably mounted on the front side of the pressing roller 41. The scraper plate 42 rests on the top of the pressing roller 41, and one end of the scraper plate 42 rests on the top of the pressing roller 41 and is tilted upward. The glass fiber yarn passes around the lower pressure roller 35 and then passes between the pressing roller 41 and the scraper plate 42. After the glass fiber yarn is coated with adhesive, when it passes through the scraper plate 42, the scraper plate 42 will scrape off the excess adhesive on the glass fiber yarn and spread the adhesive evenly.
