Description

Technical Field

[0001] This utility model relates to the field of fiberglass pipe production, and in particular to a core mold gluing device for fiberglass pipes. Background Technology

[0002] In traditional FRP pipe production, the resin coating on the core mold surface is mainly applied manually or with semi-automatic equipment. Manual spraying is inefficient, and it is difficult to ensure uniform coating. Problems such as bubbles, sagging, and uneven thickness are common in the resin layer. Although simple automated spraying equipment has been introduced, it still has the following limitations: First, the resin layer after spraying lacks an integrated, real-time smoothing and air-venting process, still requiring manual scraping for later finishing, which is not only inefficient but also results in unsatisfactory flatness. Second, it cannot effectively handle excess adhesive and bubbles generated during spraying and scraping, and dripping waste adhesive can easily contaminate the work area and affect the coating quality. Third, the overall rigidity and motion precision of the equipment are insufficient, resulting in poor stability of the spraying path when dealing with large-sized core molds.

[0003] Therefore, there is an urgent need for a fully automated gluing device that integrates spraying, smoothing, and waste glue recycling functions, so as to achieve clean production while ensuring high uniformity and flatness of the core mold glue layer. Utility Model Content

[0004] In order to overcome the shortcomings of existing devices, this utility model provides a core mold gluing device for fiberglass pipes.

[0005] The technical solution of this utility model is as follows: A core mold gluing device for fiberglass pipes includes two mounting bases. A motor is mounted on the upper left side of each mounting base. Two rotating parts are rotatably connected to the top of each mounting base. The output shaft of the motor is connected to one of the rotating parts on the right side. A core mold is placed between the rotating parts. A drive assembly is installed between the mounting bases. The drive assembly consists of a drive motor, a lead screw, and a guide rod. A first mounting frame is mounted on the drive assembly. The first mounting frame is slidably connected to the guide rod and threadedly connected to the lead screw. A mounting component is placed on the rear side of each mounting base. A spraying assembly is mounted on the mounting component. The nozzle of the spraying assembly is connected to the top of the first mounting frame. A smoothing mechanism for smoothing the glue is provided on the first mounting frame.

[0006] Preferably, the smoothing mechanism includes a second mounting bracket, and two second mounting brackets are provided on the top of the first mounting bracket, each of which is rotatably connected to a smoothing roller.

[0007] Preferably, the system also includes a scraping mechanism, which includes a third mounting frame. The third mounting frame is located at the lower part of the first mounting frame. A scraping plate is mounted on the third mounting frame. The scraping plate is located on the lower side of the core mold. An inclined structure is provided on the upper side of the scraping plate. A groove is opened beside the inclined structure. A liquid outlet is opened in the groove. A drain pipe is connected to the liquid outlet.

[0008] Preferably, the mounting component has a guide groove on its top, and the first mounting bracket is slidably connected to the guide groove.

[0009] Preferably, the second mounting bracket is provided with reinforcing ribs.

[0010] Preferably, the scraping plate has an arc-shaped upper opening structure that fits the core mold.

[0011] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0012] This invention significantly improves the efficiency and quality of adhesive application by integrating spraying, smoothing, and scraping functions on a movable frame. The precise translation of the first mounting frame combined with the uniform rotation of the core mold achieves uniform and continuous spiral spraying. The smoothing roller follows and immediately eliminates bubbles and textures in the coating. The arc-shaped scraping plate then precisely scrapes away excess adhesive. Its inclined structure concentrates waste adhesive and bubbles into the groove, which are then actively discharged through the outlet and drain pipe, effectively avoiding secondary pollution.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] A core mold gluing device for fiberglass pipes, such as Figures 1-5 As shown, the system includes two mounting bases 1. A motor 2 is mounted on the upper left side of each mounting base 1. Two rotating parts 3 are rotatably connected to the top of each mounting base 1. The output shaft of the motor 2 is connected to one of the rotating parts 3 on the right side. A mandrel 4 is placed between the rotating parts 3. A drive assembly 5 is mounted between the mounting bases. The drive assembly 5 consists of a drive motor, a lead screw, and a guide rod. A first mounting bracket 6 is mounted on the drive assembly 5. The first mounting bracket 6 is slidably connected to the guide rod and threadedly connected to the lead screw. A mandrel 4 is placed on the rear side of each mounting base 1. Mounting component 7, on which a spraying assembly 8 is mounted, the nozzle tube of the spraying assembly 8 is connected to the top of the first mounting frame 6, the top of the mounting component 7 has a guide groove, the first mounting frame 6 is slidably connected to the guide groove, the first mounting frame 6 is provided with a smoothing mechanism 9 for smoothing the adhesive, the smoothing mechanism 9 includes a second mounting frame 91, the top of the first mounting frame 6 is provided with two second mounting frames 91, each of the second mounting frames 91 is rotatably connected to a smoothing roller 92, and each of the second mounting frames 91 is provided with a reinforcing rib 93.

[0021] It also includes a scraping mechanism 10, which includes a third mounting frame 106. The third mounting frame 106 is provided at the lower part of the first mounting frame 6. A scraping plate 101 is installed on the third mounting frame 106. The scraping plate 101 is located on the lower side of the core mold 4. The scraping plate 101 has an arc-shaped upper opening structure that fits the core mold 4. A sloped structure 102 is provided on the upper side of the scraping plate 101. A groove 103 is opened on the side of the sloped structure 102. A liquid outlet 104 is opened in the groove 103. A drain pipe 105 is connected to the liquid outlet 104.

[0022] It should be noted that when the fiberglass pipe core mold 4 gluing device is in operation, the operator first places the core mold 4 to be coated horizontally between the rotating parts 3 on the top of the two mounting seats 1 for clamping. The motor 2 located on the left mounting seat 1 is then started. The motor 2 drives the rotating parts 3 to rotate synchronously, thereby causing the clamped core mold 4 to rotate stably around its own axis. Simultaneously, the drive motor of the drive assembly 5 between the mounting seats 1 is started. The motor outputs power to drive the lead screw to rotate precisely. Since the first mounting bracket 6 is engaged with the lead screw through a threaded pair and connected to the guide rod through a sliding pair, under the rotational drive of the lead screw and the limiting constraint of the guide rod, the first mounting bracket 6 moves horizontally linearly along the axial direction of the core mold 4. The spraying assembly 8 mounted on the mounting part 7... The spray nozzle is fixedly connected to the top of the first mounting bracket 6, so it moves with the first mounting bracket 6. The rotating mandrel 4, combined with the horizontally moving spray nozzle, allows the adhesive sprayed by the spraying component 8 to evenly and continuously cover the outer surface of the mandrel 4, forming a preliminary adhesive layer. The movement trajectory of the first mounting bracket 6 is limited by the guide groove on the top of the mounting component 7, ensuring smooth and precise movement. During this process, the smoothing mechanism 9, located on the top of the first mounting bracket 6, works synchronously. The two second mounting brackets 91 of this mechanism are fixed on the moving first mounting bracket 6. The smoothing rollers 92 mounted on each second mounting bracket 91 rotate with the rotation of the mandrel 4, and their elastic surfaces tightly press and roll over the outer surface of the mandrel 4 that has just been sprayed. The applied wet adhesive layer undergoes immediate and continuous rolling and smoothing operations to remove internal air bubbles, eliminate spray marks, and improve the density and smoothness of the adhesive layer. The reinforcing ribs 93 on the second mounting frame 91 effectively ensure the overall structural rigidity and operational stability of the mechanism under pressure. Following the smoothing process, the scraping mechanism 10 installed at the lower part of the first mounting frame 6 comes into play. The scraping mechanism 10 includes a third mounting frame 106 fixed to the first mounting frame 6, which supports a specially designed scraping plate 101. The scraping plate 101 is located below the rotating mandrel 4, and its structure is an upward-opening arc shape, with the arc surface closely fitting the outer contour of the mandrel 4. When the first mounting frame 6 carries the scraping plate 101 along... When the core mold 4 moves along the axial direction, the scraper plate 101 performs a secondary finishing process on the glue layer that was smoothed in the previous step. It uses its precise arc-shaped scraping edge to further smooth the glue layer and adjust the thickness. In particular, the scraper plate 101 has a carefully arranged inclined structure 102 on its upper side. During the scraping process, this inclined surface can effectively collect the excess glue that is scraped or overflowed from the surface of the core mold 4, as well as any possible micro-bubble impurities. The collected waste glue flows along the inclined surface and flows into the groove 103 opened next to the inclined structure 102. The bottom of the groove 103 is provided with a liquid outlet 104, and the collected waste glue and impurities are continuously and orderly discharged from the working area through the connected drain pipe 105, so as to avoid contaminating the glue surface of the core mold 4 that has been treated or affecting the subsequent glue coating quality.
