Description

Technical Field

[0001] This utility model relates to the technical field of hose production, and in particular to a PVC fiber reinforced hose inner mesh braiding machine. Background Technology

[0002] In the production process of PVC fiber-reinforced hoses, the inner tube is first produced by extrusion. Then, a fiber mesh is woven onto the surface of the inner tube using a crochet machine. Finally, an outer tube is extruded and laminated onto the outer layer of the mesh. In the prior art, many existing crochet machines, such as those in patent applications 202420041806.4, 201720093941.3, and 202120796273.7, only have the function of fiber weaving. However, for hoses with high strength requirements, such as fiber-reinforced hoses used in the chemical and machinery industries for conveying fluids, to improve the adhesion between the fiber mesh and the hose, workers need to manually apply a layer of adhesive to the surface of the inner tube before weaving the fiber mesh. The adhesive then enhances the adhesion between the fiber mesh and the inner tube. However, manually applying adhesive to the inner tube surface is labor-intensive and inconvenient. Therefore, a hose inner mesh crochet machine with adhesive application capabilities is needed. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a PVC fiber reinforced hose inner mesh braiding machine that can not only weave a mesh sleeve on the inner tube surface, but also apply glue to the inner tube surface, reducing labor intensity, and is easy to use and highly practical.

[0004] This utility model discloses a PVC fiber-reinforced hose inner mesh crochet machine, comprising a base plate and a crochet machine body, with the machine body mounted on the upper part of the base plate. It also includes a gluing mechanism, a guiding mechanism, a scraping mechanism, and a winding mechanism. The winding mechanism is located on the right side of the machine body, and the scraping mechanism is located on the left side, performing a scraping function. The gluing mechanism is mounted on the base plate and performs a gluing function. The guiding mechanism is also mounted on the base plate and performs a guiding function. During the production of fiber-reinforced hoses, gluing is applied to the surface of the inner tube during the process of weaving the fiber mesh onto the inner tube. During operation, the inner tube is guided by a guiding mechanism, allowing the gluing mechanism to apply glue to its surface. The glued inner tube then enters a scraping mechanism to remove excess glue, preventing the glue layer from becoming too thick. Next, the inner tube enters the crochet machine body, where a fiber mesh is crocheted onto its surface. This mesh adheres to the inner tube through the glue layer. Finally, a winding mechanism winds up the inner tube with the attached mesh. This process not only weaves a mesh onto the inner tube surface but also applies glue, reducing labor intensity and offering ease of use and high practicality.

[0005] Preferably, the glue-applying mechanism includes a housing, a motor, a glue-applying roller, and a spraying mechanism. The housing has a chamber. The motor is fixedly mounted at the front end of the housing and has a gearbox. The motor's output is connected to the glue-applying roller, which is rotatably mounted on the housing. The lower part of the glue-applying roller is located within the chamber of the housing. The output of the spraying mechanism is located above the glue-applying roller, and the input of the spraying mechanism communicates with the chamber of the housing. The chamber of the housing contains glue, and the lower part of the glue-applying roller is immersed in the glue within the chamber of the housing. When the inner tube needs to be glued to the crochet machine body, the winding mechanism and the crochet machine body and inner tube move to the right. As the inner tube moves to the right, it passes the upper end of the glue-applying roller. At the same time, the motor is turned on, and the motor drives the glue-applying roller to rotate. The rotating glue-applying roller transfers the glue in the box cavity to the lower end face of the inner tube. At the same time, the spraying mechanism is turned on, so that the glue in the box cavity is sprayed onto the upper end face of the inner tube. The glue is applied evenly to the surface of the inner tube, which facilitates the bonding between the inner tube and the fiber mesh sleeve.

[0006] Preferably, the spraying mechanism includes a delivery pump, a delivery pipe, and a nozzle. The delivery pump is fixedly installed on the housing, and the input end of the delivery pump is connected to the chamber of the housing. The output end of the delivery pump is connected to the nozzle through the delivery pipe. The nozzle is located above the coating roller, and the delivery pipe is fixedly installed on the housing. When the inner tube passes the upper end of the coating roller, the delivery pump is turned on, so that the adhesive in the housing chamber is sprayed sequentially through the delivery pipe and the nozzle onto the upper end surface of the inner tube, so as to uniformly coat the surface of the inner tube.

[0007] Preferably, the guiding mechanism includes three support plates and three guide rollers. The three support plates are all fixedly installed on the upper part of the base plate, and the three guide rollers are rotatably installed on the three support plates respectively. When the inner tube is coated with glue, the inner tube passes through the three guide rollers in sequence. The guidance of the inner tube by the three guide rollers facilitates the control of the movement trajectory of the inner tube.

[0008] Preferably, the glue scraping mechanism includes a bracket and an annular scraper, with the annular scraper fixedly mounted on the bracket. After the inner tube is coated with glue, it passes through the annular scraper and enters the crochet machine body. As the inner tube passes through the annular scraper, the annular scraper scrapes off excess glue from the surface of the inner tube, preventing the glue layer on the surface of the inner tube from becoming too thick and improving convenience.

[0009] Preferably, it also includes a collection box, which is fixedly installed on the base plate, and the bracket is fixedly installed on the upper end of the collection box. The upper end of the collection box is set as an opening. With the above configuration, after the annular scraper scrapes the glue on the surface of the inner tube, the glue will fall into the collection box for collection, which facilitates the collection of glue.

[0010] Preferably, the winding mechanism includes a vertical plate, a rotating shaft, a winding roller, and a drive motor. The vertical plate is fixedly mounted on the base plate, the drive motor is mounted on the vertical plate, the rotating shaft is rotatably mounted on the vertical plate, and the winding roller is fixedly mounted on the rotating shaft. The input end of the rotating shaft is connected to the drive motor. After the crochet machine body weaves the fibers into a mesh on the surface of the inner tube, one end of the inner tube is wound around the winding roller. Then, the drive motor is turned on, causing the rotating shaft to drive the winding roller to rotate. The rotating winding roller winds up the inner tube, which facilitates the winding of the inner tube.

[0011] Compared with the prior art, the advantages of this utility model are: it can not only weave a mesh sleeve on the surface of the inner tube, but also apply glue to the surface of the inner tube, which reduces labor intensity, is convenient to use, and has high practicality.

This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example

[0019] like Figures 1 to 5The PVC fiber-reinforced hose inner mesh crochet machine of this utility model includes a base plate 1, a crochet machine body 2, a glue application mechanism, a guiding mechanism, a glue scraping mechanism, and a winding mechanism. The crochet machine body 2 is installed on the upper end of the base plate 1.

The glue scraping mechanism has the function of scraping glue. The glue application mechanism is installed on the base plate 1 and has the function of applying glue. The guiding mechanism is installed on the base plate 1 and has the function of guiding. In the process of producing fiber-reinforced hoses, when it is necessary to apply glue to the surface of the inner tube 17 during the process of weaving the fiber mesh on the surface of the inner tube 17, the guiding mechanism guides the inner tube 17. The inner tube 17 is guided so that the glue-applying mechanism applies glue to its surface. After the glue is applied, the inner tube 17 enters the glue-scraping mechanism, which scrapes off excess glue from the surface of the inner tube 17 to prevent the glue layer from becoming too thick. Then, the inner tube 17 enters the crochet machine body 2, where the crochet machine body 2 crochets a fiber mesh onto the surface of the inner tube 17, allowing the mesh to adhere to the surface of the inner tube 17 through the glue layer. Finally, the winding mechanism winds up the inner tube 17 with the mesh attached. This method not only weaves a mesh onto the surface of the inner tube 17 but also applies glue to its surface, reducing labor intensity, making it convenient to use and highly practical.

[0020] like Figure 1 and Figure 3 The glue-applying mechanism includes a housing 3, a motor 4, a glue-applying roller 5, and a spraying mechanism. The housing 3 has a chamber. The motor 4 is fixedly mounted at the front end of the housing 3 and has a gearbox. The output end of the motor 4 is connected to the glue-applying roller 5, which is rotatably mounted on the housing 3. The lower part of the glue-applying roller 5 is located within the chamber of the housing 3. The output end of the spraying mechanism is located above the glue-applying roller 5, and the input end of the spraying mechanism communicates with the chamber of the housing 3. The chamber of the housing 3 contains glue, and the lower part of the glue-applying roller 5 is immersed in the glue within the chamber of the housing 3. When the inner tube 17... When it is necessary to apply glue to the body 2 of the crochet machine, the winding mechanism and the body 2 of the crochet machine and the inner tube 17 move to the right. While the inner tube 17 moves to the right, it passes the upper end of the glue application roller 5. At the same time, the motor 4 is turned on, and the motor 4 drives the glue application roller 5 to rotate. The rotating glue application roller 5 transfers the glue in the chamber of the box 3 to the lower end face of the inner tube 17. At the same time, the spraying mechanism is turned on, so that the glue in the chamber of the box 3 is sprayed onto the upper end face of the inner tube 17. The glue is evenly applied to the surface of the inner tube 17, which facilitates the bonding between the inner tube 17 and the fiber mesh sleeve.

[0021] like Figure 1 , Figure 3 and Figure 4The spraying mechanism includes a delivery pump 6, a delivery pipe 7, and a nozzle 8. The delivery pump 6 is fixedly installed on the housing 3. The input end of the delivery pump 6 is connected to the chamber of the housing 3, and the output end of the delivery pump 6 is connected to the nozzle 8 through the delivery pipe 7. The nozzle 8 is located above the coating roller 5. The delivery pipe 7 is fixedly installed on the housing 3. When the inner tube 17 passes the upper end of the coating roller 5, the delivery pump 6 is turned on, so that the adhesive in the chamber of the housing 3 is sprayed onto the upper end surface of the inner tube 17 through the delivery pipe 7 and the nozzle 8 in sequence, so as to uniformly coat the surface of the inner tube 17.

[0022] like Figure 1 and Figure 2 The guiding mechanism includes three support plates 9 and three guide rollers 10. The three support plates 9 are fixedly installed on the upper end of the base plate 1, and the three guide rollers 10 are rotatably installed on the three support plates 9 respectively. When the inner tube 17 is coated with glue, the inner tube 17 passes through the three guide rollers 10 in sequence. The three guide rollers 10 guide the inner tube 17, which facilitates the control of the movement trajectory of the inner tube 17.

[0023] like Figure 1 and Figure 5 The glue scraping mechanism includes a bracket 11 and an annular scraper 12, with the annular scraper 12 fixedly mounted on the bracket 11. After the inner tube 17 is coated with glue, it passes through the annular scraper 12 and enters the crochet machine body 2. As the inner tube 17 passes through the annular scraper 12, the annular scraper 12 scrapes off the excess glue from the surface of the inner tube 17, preventing the glue layer on the surface of the inner tube 17 from becoming too thick and improving convenience.

[0024] like Figure 5 The system also includes a collection box 13, which is fixedly mounted on the base plate 1. A bracket 11 is fixedly mounted on the upper end of the collection box 13, and the upper end of the collection box 13 is set as an opening. With the above arrangement, after the annular scraper 12 scrapes the glue on the surface of the inner tube 17, the glue will fall into the collection box 13 for collection, which facilitates the collection of glue. The winding mechanism includes a vertical plate 14, a rotating shaft 15, a winding roller 16, and a drive motor. The vertical plate 14 is fixedly mounted on the base plate 1, the drive motor is mounted on the vertical plate 14, the rotating shaft 15 is rotatably mounted on the vertical plate 14, and the winding roller 16 is fixedly mounted on the rotating shaft 15.

After the crochet machine body 2 weaves the fibers into a mesh on the surface of the inner tube 17, one end of the inner tube 17 is wound around the winding roller 16. Then, the drive motor is turned on, so that the rotating shaft 15 drives the winding roller 16 to rotate. The rotating winding roller 16 winds up the inner tube 17, which facilitates the winding of the inner tube 17. Example

[0025] Based on Example 1, a drying mechanism is added. The drying mechanism is located between the crochet machine body 2 and the winding mechanism. The drying mechanism can use an electric heating lamp or a hot air blower to promote the curing of the glue on the surface of the inner tube 17.
