Description

Technical Field

[0001] This utility model relates to the technical field of fiberglass tanks, and in particular to a fiberglass tank demolding and trimming device. Background Technology

[0002] After demolding, fiberglass tanks may have some burrs or other defects. At this point, the demolded fiberglass tanks need to be trimmed. Although existing trimming devices can trim fiberglass tanks, they generally use a grinding head. The grinding head works in conjunction with other transmission components to perform a comprehensive trimming of the fiberglass tank. This operation requires frequent adjustments to the position and angle of the grinding head, which not only wastes time but also reduces work efficiency. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a demolding and trimming device for fiberglass tanks.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A fiberglass tank demolding and trimming device includes a base plate, with vertical rods connected to the four corners of the base plate. Multiple sets of vertical rods are equipped with corresponding rollers, and the same sandpaper is wound and installed on the rollers. Arc-shaped plates are placed at each of the vertical rods. Multiple sets of round rods are connected to the base plate, and each round rod movably penetrates a corresponding frame. Springs are fitted to the outer walls of each round rod with clearance. One end of each spring is connected to the base plate, and the other end is connected to the corresponding frame. Rollers are rotatably connected to each frame, and each roller contacts the sandpaper.

[0006] Preferably, each of the multiple sets of vertical rods has multiple sets of tenons, and each of the multiple sets of tenons is movably connected to a tenon block, and each of the multiple sets of tenons is connected to the corresponding arc-shaped plate.

[0007] Preferably, each of the multiple sets of vertical rods and arc-shaped plates is movably connected with ball bearings, and each of the multiple sets of ball bearings is in contact with the corresponding roller.

[0008] Preferably, one end of each of the multiple sets of rollers and idlers is machined with a side plate, and one end of the sandpaper is in contact with the side plate in the corresponding direction.

[0009] Preferably, each of the multiple sets of rollers is connected to a rocker arm, each of the multiple sets of rocker arms is threaded with a bolt, and each of the multiple sets of bolts is threadedly connected to the corresponding vertical rod.

[0010] Preferably, the multiple sets of idlers are distributed at equal intervals.

[0011] Preferably, the hand grips of all the rocker arms are covered with anti-slip rubber sleeves.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Through the coordination of sandpaper, rollers, round rods, frames, support rollers, and springs, the fiberglass can is placed on the sandpaper section of multiple sets of support rollers and rotated with the help of external equipment. At this time, the downward pressure of the fiberglass can causes the multiple sets of support rollers to move with the elastic force of the springs and the frame to move in the lifting position of the round rod, quickly making appropriate contact between the sandpaper and fiberglass cans of different sizes. When the fiberglass can rotates, the sandpaper can be used for finishing work after demolding. It can also be sanded according to the shape of the outer wall, and can fit closely to the outer wall of the can, ensuring that every part is fully and evenly sanded, which greatly improves the sanding accuracy and quality, makes the surface of the fiberglass can smoother and flatter, improves the appearance quality of the product, and is relatively time-saving and ensures work efficiency.

[0014] 2. By using the combination of vertical rods, curved plates, sandpaper, tenons and mortises, and by connecting the curved plates and vertical rods with the tenons and mortises, disassembly and assembly operations can be carried out quickly. This makes it easy to disassemble and assemble the rollers, and then, according to the actual finishing needs after demolding of the fiberglass tank, appropriate sandpaper can be used for polishing.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figures 1 to 5 A fiberglass can demolding and finishing device includes a base plate 1, with vertical rods 2 connected to each of the four corners of the base plate 1. The base plate 1 serves as the basic load-bearing component of the entire device, providing a stable support surface. The vertical rods 2, extending vertically upwards from the base plate 1, form the basic frame of the device. This structural design ensures the stability of the entire device during operation, enabling it to withstand the forces generated by the fiberglass can and related operations. Multiple sets of vertical rods 2 are equipped with corresponding rollers 3, on which the same sandpaper 4 is wound and installed. The sandpaper 4 is the direct working component for grinding and finishing the fiberglass can, and its material and grit can be adjusted according to the surface condition of the fiberglass can and the grinding requirements. For example, for fiberglass cans with large surface roughness and many defects, coarser sandpaper 4 can be used for initial grinding to remove larger burrs and defects; while for fiberglass cans with higher surface requirements and needing fine finishing, finer sandpaper 4 can be used for final polishing. The design of the roller 3 facilitates the installation and replacement of the sandpaper 4, and also controls the tension of the sandpaper 4 to a certain extent, ensuring stability during the sanding process. Arc plates 9 are placed at multiple sets of vertical rods 2, and multiple sets of round rods 5 are connected to the base plate 1. The multiple sets of round rods 5 are movably connected to the corresponding frame 6, and the frame 6 can move up and down along the round rods 5. This movable connection method provides a key structural basis for the adaptive sanding function of the device. Springs 8 are fitted with gaps on the outer walls of multiple sets of round rods 5. One end of multiple sets of springs 8 is connected to the base plate 1, and the other end of multiple sets of springs 8 is connected to the corresponding frame 6. Rollers 7 are rotatably connected to multiple sets of frame 6, and multiple sets of rollers 7 are in contact with the sandpaper 4. Due to the close contact between the rollers 7 and the sandpaper 4, the sanding force can be effectively transmitted, ensuring the sandpaper 4's sanding effect on the outer wall of the fiberglass tank. When different fiberglass tanks have different specifications, the roller 7 can adaptively adjust its position under the action of the spring 8, so that the sandpaper 4 always maintains good contact with the outer wall of the tank, thereby realizing the sanding work adapted to the shape of the outer wall.

[0023] In this embodiment, multiple sets of tenons 12 are provided at each of the multiple sets of vertical rods 2, and tenons 11 are movably connected to each of the multiple sets of tenons 12. The multiple sets of tenons 11 are respectively connected to the corresponding arc-shaped plates 9. Through the cooperation of the tenons 11 and the tenons 12, the arc-shaped plates 9 can be quickly installed and disassembled, which facilitates the replacement and maintenance of the rollers 3. For example, when it is necessary to replace rollers 3 of different specifications or with severe wear, simply remove the arc-shaped plates 9 to easily take out the rollers 3 for replacement. At the same time, different sandpaper 4 can also be replaced for repair work. Ball bearings 10 are movably connected to the multiple sets of vertical rods 2 and arc-shaped plates 9. The multiple sets of ball bearings 10 are respectively in contact with the corresponding rollers 3. The introduction of ball bearings 10 greatly reduces the friction of the rollers 3 during rotation and improves the rotation efficiency of the rollers 3. During the loading and unloading of sandpaper 4, the rollers 3 need to rotate frequently. If the friction is too high, it will not only increase the labor intensity of the operator, but may also cause uneven wear or breakage of the sandpaper 4. The presence of the ball bearing 10 allows the roller 3 to rotate more smoothly, ensuring the stable loading and unloading of the sandpaper 4, and also extending the service life of the sandpaper 4 and the roller 3. Multiple sets of rollers 3 and support rollers 7 have side plates machined at one and the other ends. These side plates act as guides, ensuring the stability of the sandpaper 4. One and the other ends of the sandpaper 4 are in contact with the corresponding side plates. Multiple sets of rollers 3 are connected to rocker arms 13, and each rocker arm 13 is threaded with a bolt 14. Each bolt 14 is threaded onto a corresponding vertical rod 2. The rocker arm 13 is the handle used by the operator to control the rotation of the roller 3. By turning the rocker arm 13, the loading and unloading of the sandpaper 4 can be achieved. The bolt 14 is used to fix the roller 3 after the sandpaper 4 is adjusted to the appropriate position, preventing it from rotating accidentally during sanding. When it is necessary to replace the sandpaper 4 or adjust the tension of the sandpaper 4, first loosen the bolt 14, then turn the rocker arm 13 to perform the corresponding operation. After the operation is completed, tighten the bolt 14. Multiple sets of rollers 7 are evenly distributed to ensure the stability of the frame 6 during the lifting process, so that the rollers 7 can evenly adapt to the shape of the fiberglass tank. The handles of multiple sets of rocker arms 13 are all covered with anti-slip rubber sleeves.

[0024] The working principle of this embodiment is as follows: During use, external equipment brings the demolded fiberglass can into contact with the sandpaper 4 area on multiple sets of rollers 7. At the same time, with the help of downward pressure, the multiple sets of rollers 7 will make contact according to the specifications of the fiberglass can, so that the sandpaper 4 can fully contact the fiberglass can. After contact, the bolt 14 is connected to the thread of the vertical rod 2 to lock the roller 3, restricting the release and retraction of the sandpaper 4. With the help of external equipment to rotate the fiberglass can, the fiberglass can will be fully repaired and polished by the sandpaper 4. After the repair work is completed, the rotation of the rocker arm 13 can be used to retract and release the sandpaper 4 on the roller 3 to replace the sandpaper 4 in the area of ​​the roller 7, so as to ensure the subsequent repair operation of the fiberglass can. Alternatively, the arc plate 9 can be separated from the vertical rod 2, the roller 3 can be disassembled, and the sandpaper 4 can be replaced as a whole to meet the needs of using different sandpaper 4 for repairing and polishing different fiberglass cans.
