Description

Technical Field

[0001] The utility model relates to the technical field of cutting, in particular to a glass fiber reinforced plastic pultruded pipe cutting device. Background Art

[0002] FRP pultruded pipes are mainly used in the fields of power cable protection casings, etc. They are composed of an inner braided layer, an intermediate layer and an outer braided layer. They are formed by pultrusion process. This material is reinforced with high-strength glass fiber composite materials, which are wound, cured and composited. During the production process, it is formed into a long pipe, which needs to be cut in sections according to the customized size to ensure that the size and shape of the product meet the requirements. A slitting machine is needed for cutting. First, mark the cutting position on the outside of the pultruded pipe according to the required size, and then install it on the driving roller of the slitting machine. By driving it to rotate, it cooperates with the movable cutting tool to cut the pultruded pipe into sections. Since the pipe is made of composite materials such as glass fiber and resin, more fiber debris will be generated during the cutting process. On the one hand, the fiber debris will float into the air, and the inhalation of the staff will affect the respiratory health. On the other hand, the debris will accumulate on the workbench, and the subsequent cleaning will be more laborious. If it stays between the cutting tool and the pipe for a long time, burrs will appear on the cutting surface, and the cutting quality will be poor. Utility Model Content

[0027] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0028] Example

[0029] As mentioned in the background technology, since the FRP pultruded pipe is made of composite materials such as glass fiber and resin, it is easy to generate a lot of fiber debris during the cutting process. The inventor found in the factory that part of the limiting debris generated floats in the air, and part falls on the cutting platform 1, which is easy to affect the respiratory health of the staff and increase the burden of cleaning the cutting platform 1 later. In addition, due to the presence of debris, burrs often appear on the cutting surface. Therefore, the inventor has made improvements and innovations on the basis of the existing slitting machine and designed a chip removal component 7. The chip removal component 7 can move with the cutting tool 5, which greatly reduces the floating of fiber debris. The following is a detailed explanation in conjunction with the diagram.

[0030] This embodiment provides a glass fiber reinforced plastic pultruded pipe cutting device, see Figure 1 and Figure 2, including a cutting platform 1, a driving roller 2 is installed on the upper end of the cutting platform 1 through a frame, and the driving roller 2 is arranged near the front end of the cutting platform 1, the driving roller 2 is rotatably installed, and the driving roller 2 is driven to rotate by a power device 3. In this embodiment, the power device 3 adopts the form of a driving motor and a belt combination, and the driving motor of the driving roller 2 is arranged at the bottom of the cutting platform 1.

[0031] In this embodiment, a cutting tool 5 is provided on the cutting platform 1 on one side of the driving roller 2. The rotation of the cutting tool 5 adopts the rotation drive form of the existing slitting machine. The cutting tool 5 is installed on the tool table 4, and the tool table 4 can move along the extension (length) direction of the driving roller 2. It can be seen in the figure that the tool table 4 is provided with a driving component, which is connected to the cutting tool 5 and is driven to move by a lead screw in the prior art. No unnecessary details are given, which can drive the cutting tool 5 to move in a direction close to or away from the driving roller 2, and can cut pipes of different diameters installed on the driving roller 2. The movement of the tool table 4 is driven by a lead screw sleeve combination 15 provided on the cutting platform 1. The sleeve is installed at the bottom of the tool table 4 and is threadedly connected to the lead screw. The lead screw is driven to rotate by the driving motor, thereby driving the tool table 4 to move along the extension direction of the driving roller 2.

[0032] As one of the main technical concepts of the utility model, a mounting plate 6 is provided on the cutting platform 1 on the other side of the driving roller 2, and the mounting plate 6 can move in a direction close to or away from the driving roller 2. In order to achieve the movement of the mounting plate 6 and the stability when it is stationary, two racks 10 are provided on the cutting platform 1, and an opening is provided on the side of the mounting plate 6 away from the centrifugal fan 72, the width of the opening is greater than the maximum distance between the two racks 10, and a driving shaft 11 is rotatably connected in the opening, and a gear 12 meshing with the rack 10 is installed on the outer side of the driving shaft 11. By setting the gear 12 and the rack 10, the mounting plate 6 can be pushed to move, and by the meshing of the gear 12 and the rack 10, a limit can be provided for the mounting plate 6 when it is stationary, to avoid displacement of the mounting plate 6 due to vibration or linkage, thereby ensuring its stability.

[0033] In order to support the mounting plate 6 and reduce the meshing pressure between the gear 12 and the rack 10, a slide rail 13 is arranged on the cutting platform 1 outside the rack 10, and a slide block 14 is arranged at the bottom of the mounting plate 6 to slide with the slide rail 13. The setting of the slide block 14 can support the mounting plate 6, and the slide block 14 should be arranged at the bottom of the mounting plate 6 on the side away from the gear 12. The height setting should ensure that the bottom of the mounting plate 6 does not contact the rack 10. When the mounting plate 6 slides, the slide block 14 slides back and forth along the slide rail 13. When cutting, the mounting plate 6 is pushed to move, driving the centrifugal fan 72 to move to a position close to the pipe installed on the driving roller 2, keeping the distance between the air inlet and the pipe at about 10 cm, and ensuring that the debris is sucked away and collected as soon as possible.

[0034] On the basis of the above structure, a chip removal assembly 7 is movably arranged on the mounting plate 6, and the chip removal assembly 7 is connected to one side of the tool platform 4 through a telescopic rod 8. When the tool platform 4 moves, the chip removal assembly 7 is connected to the tool platform 4 through a telescopic rod 8. Figure 3 , which can drive the chip removal component 7 to move with it. Specifically, the chip removal component 7 includes a bottom plate 71 movably mounted on the mounting plate 6, and a centrifugal fan 72 is mounted on the bottom plate 71. The air inlet of the centrifugal fan 72 faces the side of the driving roller 2, and the air inlet of the centrifugal fan 72 is in the same vertical plane as the cutting tool 5. It can be ensured that when the centrifugal fan 72 moves with the tool platform 4, the air inlet of the centrifugal fan 72 is always in a position flush with the cutting tool 5, and the generated dust can be immediately removed. The debris is sucked away and collected. The specific location where the debris is collected is that the air outlet of the centrifugal fan 72 is connected to the debris box 75 through the bellows 74. The setting of the bellows 74 can cooperate with the movement of the centrifugal fan 72 on the bottom plate 71. The air outlet is connected to the debris box 75. Specifically, the bottom plate 71 of the chip removal assembly 7 is connected to the telescopic rod 8 on the side close to the driving roller 2. Through the linkage of the telescopic rod 8, the tool table 4 drives the bottom plate 71 to move, and then drives the centrifugal fan 72 on the bottom plate 71 to move.

[0035] Moreover, in order to realize the translation of the base plate 71 on the mounting plate 6 along with the tool table 4, a slide groove 9 is opened on the mounting plate 6, and the slide groove 9 is opened along the extension direction of the driving roller 2, wherein the slide groove 9 is opened with two, and a slider 73 sliding with the slide groove 9 is set at the bottom of the base plate 71, and the slider 73 is set corresponding to the slide groove 9. Two sliders 73 are set respectively to slide with the corresponding slide grooves 9, thereby realizing the sliding of the base plate 71 on the mounting plate 6, and the setting of the two slide grooves 9 makes the translation of the base plate 71 more stable.

[0036] On the basis of the above structure, the length difference between the slide groove 9 and the slider 73 is not less than the length of the driving roller 2, and the slide groove 9 is arranged at the middle position of the mounting plate 6, so as to ensure that the position of the centrifugal fan 72 moving with the bottom plate 71 can cover the entire driving roller 2, which not only ensures that the cutting tool 5 can be cut at any position and prevents the cutting tool 5 from being limited, but also enables the centrifugal fan 72 to cooperate with the cutting tool 5 to perform chip removal at any cutting position.
