Description

Technical Field

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

[0002] FRP pipe (Fiber Reinforced Plastic pipe) is a composite material pipe made of glass fiber as reinforcement material and resin as matrix material through winding, molding and other processes. It combines the high strength of glass fiber and the corrosion resistance of resin, and is widely used in water supply and drainage, chemical industry, petroleum, electricity, seawater desalination, sewage treatment and other fields.

[0003] In the cutting operation of FRP pipes, due to its special material, the cutting process will inevitably release a large amount of fine fiber debris and dust. These particles not only pose a hidden danger of environmental pollution, but also pose a direct threat to the health of on-site operators, and may cause irritation reactions through respiratory inhalation or skin contact. Traditionally, in order to alleviate this problem, water spraying dust reduction methods are often used, but this method often takes the form of direct spraying or excessive irrigation, which not only leads to serious waste of water resources, but more importantly, in the cutting area, especially the contact interface between the cutting disc and the FRP pipe, it is difficult to accurately deliver water, forming a blind spot for dust reduction, so that dust and fibers still have the opportunity to escape into the air and continue to harm the environment and human health.

[0004] Based on this, the invention discloses a cutting device for processing glass fiber reinforced plastic pipes. Summary of the invention

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] Existing cutting equipment will generate a lot of dust and fiber debris when cutting FRP pipes, while the traditional water spray dust reduction method is too wasteful and the dust reduction is not accurate.

[0053] To this end, the present invention provides a cutting device for glass fiber reinforced plastic pipe processing, see Figure 1 As shown, it includes a gantry 1 and a bracket 4, a roller 2 is provided on the bracket 4 to drive the glass fiber reinforced plastic pipe to rotate, a telescopic rod 5 is provided on the gantry 1, a mounting plate 6 is provided at the bottom end of the telescopic rod 5, a driving component 7 is provided at the bottom end of the mounting plate 6, and a cutting component 8 is provided at the output end of the driving component 7 to cut the glass fiber reinforced plastic pipe.

[0054] For details, see Figure 1 and Figure 3 As shown, a water adding component 9 is also provided on the gantry 1 for adding water to the cutting component 8. Figure 4 As shown, the cutting assembly 8 includes a first cutting disc 81 and a second cutting disc 82, the first cutting disc 81 is connected to the output end of the driving assembly 7, the first cutting disc 81 and the second cutting disc 82 are detachably connected, a plurality of cutting openings 84 are provided on the edges around the first cutting disc 81 and the second cutting disc 82 for cutting the glass fiber reinforced plastic pipe, a plurality of drainage grooves 83 are provided on the opposite sides of the first cutting disc 81 and the second cutting disc 82, a plurality of water injection grooves 85 are provided on the opposite sides of the first cutting disc 81 and the second cutting disc 82, and the water adding assembly 9 accurately adds water to the cutting position of the first cutting disc 81 and the second cutting disc 82 and the glass fiber reinforced plastic pipe through the drainage grooves 83 and the water injection grooves 85 to prevent dust and fiber debris from flying into the air; in addition, the first cutting disc 81 and the second cutting disc 82 are detachably connected to facilitate the subsequent cleaning of the drainage grooves 83 and the water injection grooves 85. At the same time, it should be noted that in the working state, the first cutting disc 81 and the second cutting disc 82 are fitted and fixedly connected.

[0055] For further information, see Figure 3-Figure 5 As shown, the driving assembly 7 includes a driving motor 71 fixedly mounted on the bottom end of the mounting plate 6 , the output end of the driving motor 71 is connected to a transmission shaft 72 , and a plurality of limit blocks 73 are fixedly mounted on the end of the transmission shaft 72 .

[0056] Among them, see Figure 4-Figure 5 and Figure 7As shown, a mounting disk 87 is fixedly provided on one side of the center position of the first cutting disk 81 close to the transmission shaft 72, and a plurality of limiting grooves 88 compatible with the limiting blocks 73 are opened on the mounting disk 87; thus, in the working state, the transmission shaft 72 is actually only fixedly connected to the mounting disk 87 on the first cutting disk 81, and the first cutting disk 81 and the second cutting disk 82 are driven to rotate through the carding and limiting of the limiting blocks 73 and the limiting grooves 88.

[0057] In addition, see Figure 4 , Figure 8 and Fig.13 As shown, a mounting groove 811 is provided at the center of the first cutting disc 81 and the second cutting disc 82, and a water storage box 111 is rotatably connected in the mounting groove 811. Fig. 9 and Fig.10 As shown, a plurality of first water inlets 89 corresponding to the drainage grooves 83 and a second water inlet 810 corresponding to the water injection grooves 85 are provided on the inner wall of the installation groove 811; it should be noted that the installation groove 811 is provided at the center position of the first cutting disk 81 and the second cutting disk 82.

[0058] Furthermore, see Figure 9-10 and Fig.13 As shown, the drainage groove 83 and the water injection groove 85 are arranged adjacent to each other and are the same in number. Several groups of drainage grooves 83 and water injection grooves 85 are evenly arranged. The water injection grooves 85 on the first cutting disc 81 and the second cutting disc 82 are symmetrically arranged. One end of the two water injection grooves 85 is connected to the second water injection port 810 on the mounting groove 811, and the other end passes through the edge of the first cutting disc 81 and the second cutting disc 82 to form a through opening; in this way, the water injection grooves 85 on the first cutting disc 81 and the second cutting disc 82 can jointly form a closed groove, which is convenient for subsequent water flow to flow from the second water injection port 810 into the water injection groove 85, and be thrown to the through opening at the edge of the first cutting disc 81 and the second cutting disc 82 by centrifugal force, so that water is directly applied to the cutting part with the glass fiber reinforced plastic pipe during cutting, so as to achieve precise water addition;

[0059] like Figure 7 and Fig.10 As shown, a water outlet 86 is provided in the drainage groove 83 adjacent to the mounting groove 811, and the first water injection port 89 is connected to the water outlet 86, and the inner diameter of the first water injection port 89 is larger than the inner diameter of the water outlet 86. It should be noted that the water injection groove 85 is arranged inside the first cutting disc 81 and the second cutting disc 82, and the drainage groove 83 is arranged on the outer surface of the first cutting disc 81 and the second cutting disc 82; it should also be noted that the end of the drainage groove 83 away from the mounting groove 811 is connected to the cutting port 84, and the end of the water injection groove 85 away from the mounting groove 811 is connected to the smooth surface of the outer edge of the first cutting disc 81 and the second cutting disc 82;

[0060] Firstly, the water outlet 86 is provided in the installation groove 811 so that when the water flows out of the water outlet 86, it can directly act on the cutting opening 84 along the drainage groove 83 by means of centrifugal force. It should be added that the drainage groove 83 is arranged on the outer surface of the first cutting disc 81 and the second cutting disc 82 because during the cutting process, especially when the edges of the first cutting disc 81 and the second cutting disc 82 have penetrated the glass fiber reinforced plastic pipe, the effect of the water injection groove 85 at the outermost edge of the first cutting disc 81 and the second cutting disc 82 on adding water to the cutting part will be reduced because it has passed through the glass fiber reinforced plastic pipe. At this time, the drainage groove 83 on the outer surface of the first cutting disc 81 and the second cutting disc 82 plays a major role in adding water, and it acts directly on the cutting opening 84. The water thrown out by the centrifugal force can add water to the cutting part more accurately and effectively. Secondly, the diameter of the first water injection port 89 is larger than that of the water outlet 86 in order to facilitate the water to quickly flow into the water outlet 86 after passing through the first water injection port 89. Fig.10 As shown by the dotted line, because the water outlet 86 is opened perpendicular to the outer surfaces of the first cutting disk 81 and the second cutting disk 82, the flow direction of the water is non-linear, so the flow rate needs to be increased to ensure that the water can flow out of the water outlet 86, and then directly acted upon by centrifugal force to flow to the cutting port 84 through the drainage groove 83.

[0061] For details, see Figure 1 and Figure 3 As shown, the water adding assembly 9 includes a water tank 91 arranged on the gantry 1, and the water tank 91 is connected with a spiral tube 92, and the spiral tube 92 is connected to the water adding pipe 93. The spiral tube 92 is used to increase the length of the water adding pipe 93, and the water adding pipe 93 is connected to the water storage box 111. In this way, when the telescopic rod 5 drives the cutting assembly 8 to move up and down, the water adding pipe 93 can also move accordingly without being restricted by the length.

[0062] For further information, see Fig.11 , Fig.13 and Fig.15 As shown, a plurality of openings 112 are provided around the water storage box 111, and the openings 112 are adapted to the widths of the two symmetrically arranged first water injection ports 89, and the number of the openings 112 is the same as the number of the second water injection ports 810; the reason why the width of the openings 112 is set to be adapted to the width of the two first water injection ports 89 is because the first cutting disc 81 and the second cutting disc 82 both have the first water injection ports 89, and the second water injection port 810 is formed by merging two water injection grooves 85, and secondly, the number thereof is required to be the same as the second water injection port 810, which paves the way for the cyclic pumping and water injection actions mentioned below, so that it can be ensured that the water storage box 111 is connected to the second water injection port 810 at the same time, or is connected to the first water injection port 89 at the same time, or the first water injection port 89 and the second water injection port 810 are sealed at the same time.

[0063] Preferably, see Figure 2 and Figure 3 As shown, an axial flow impeller 74 is rotatably connected in the water storage box 111, and the axial flow impeller 74 is fixedly connected to the end of the transmission shaft 72. It should be added here that the end of the transmission shaft 72 extends into the water storage box 111 and is fixedly connected to the axial flow impeller 74, so that the rotation of the transmission shaft 72 can drive the axial flow impeller 74 and the first cutting disk 81 and the second cutting disk 82 to rotate synchronously, and the water storage box 111 is fixedly connected to the mounting plate 6 through a connecting rod, and the outer wall of the water storage box 111 fits with the inner wall of the mounting groove 811. The water storage box 111 is fixed compared to the mounting plate 6, and the first cutting disk 81 and the second cutting disk 82 rotate, so that the water storage box 111 rotates relative to the mounting groove 811. In addition, the water storage box 111 and the mounting groove 811 are sealed and rotatably connected to the mounting groove 811, ensuring that the water storage box 111 will not affect the rotation of the first cutting disk 81 and the second cutting disk 82, while ensuring the sealing between the opening 112 and the first water injection port 89 and the second water injection port 810.

[0064] Furthermore, Figure 12-Figure 17 As shown, the first cutting disc 81 and the second cutting disc 82 rotate, and the opening 112 on the water storage box 111 and the first water injection port 89 and the second water injection port 810 on the mounting groove 811 work as follows:

[0065] The first state, such as Fig.13 As shown, when the opening 112 and the second water injection port 810 rotate to overlap, the water in the water storage box 111 is sent into the second water injection port 810 by gravity and the centrifugal force of the axial flow impeller 74, and then flows into the cutting position through the water injection groove 85 by centrifugal force; at this time, the first water injection port 89 is in a sealed state;

[0066] The second state, such as Fig.15 As shown, the opening 112 overlaps with the two first water inlets 89, and the water in the water storage box 111 enters the first water inlet 89. At this time, the second water inlet 810 is sealed, so that the water in the water storage box 111 will only be sent to the first water inlet 89, and then flow out through the water outlet 86, and then be sent to the cutting port 84 along the drainage groove 83 by centrifugal force, so that it acts on the cutting position;

[0067] The third state, such as Fig.17 As shown, the opening 112 coincides with the inner wall of the mounting groove 811. Fig.17The dotted line part shows that at this time, the first water injection port 89 and the second water injection port 810 are both sealed. At this time, except for the connection with the water supply pipe 93, the other openings 112 in the entire water storage box 111 are all sealed, so the negative pressure generated by the rotation of the axial flow impeller 74 of the water storage box 111 can pump water from the water tank 91 through the water supply pipe 93; then the opening 112 continues to overlap with the second water injection port 810, and the cycle continues, so that the water storage box 111 can always keep pumping water from the water tank 91, and then the centrifugal force of the axial flow impeller 74 is used to send water to the second water injection port 810 and the first water injection port 89 in order, and then it is sealed again for pumping water;

[0068] Through the above-mentioned cyclic process of pumping and delivering water, the purpose of completing accurate water addition in order and steps is achieved, and at the same time, the purpose of accurate water addition can be achieved in two stages: the initial cutting and after the first cutting disk 81 and the second cutting disk 82 pass through the fiberglass pipe, thereby avoiding the disadvantage of being unable to accurately add water after the first cutting disk 81 and the second cutting disk 82 pass through the fiberglass pipe. Moreover, through the above cyclic process, water is added purposefully in steps, which not only improves the efficiency of water addition, but also greatly saves water, and also eliminates the water pump component, saving costs.

[0069] In addition, Figure 1-Figure 3 As shown, a water receiving pool 3 is also provided on the bracket 4, and a guide cover 10 is fixedly provided on the mounting plate 6. The guide cover 10 is of a semicircular structure, and one end of the bottom of the guide cover 10 is fixedly provided with a groove facing the water receiving pool 3. The guide cover 10 is located directly above the first cutting disc 81 and the second cutting disc 82, and is of a semi-wrapped structure for the first cutting disc 81 and the second cutting disc 82. The guide cover 10 is used to block the water thrown out of the drainage groove 83 and the water injection groove 85, and drain it into the water receiving pool 3; it should be noted that after the above-mentioned cycle of adding water and pumping water, and the action of adding water The drainage groove 83 and the water injection groove 85 on the first cutting disk 81 and the second cutting disk 82 directly act on the cutting position, so that the disadvantage of sewage splashing will be reduced, so the size of the baffle can be reduced to optimize the space, and then only the deflector 10 is set here, and a groove is set at the bottom of the deflector 10 to directly introduce the sewage into the water receiving pool 3. In addition, the width of the deflector 10 is slightly larger than the width of the first cutting disk 81 and the second cutting disk 82 after being combined, and there is a rotation space left in the deflector 10 and the first cutting disk 81 and the second cutting disk 82.

[0070] Working principle:

[0071] During specific operation, the FRP pipe is placed on the roller 2, and then the roller 2 drives the FRP pipe to rotate, then the driving motor 71 is started, and then the first cutting disc 81 and the second cutting disc 82 act on the FRP pipe through the telescopic rod 5, and the FRP pipe rotates to complete the cutting of one circle;

[0072] The transmission shaft 72 of the driving motor 71 rotates and drives the first cutting disc 81 and the second cutting disc 82 to rotate after being engaged with the limiting groove 88 on the mounting disc 87 through the limiting block 73, and the first cutting disc 81 and the second cutting disc 82 are in a merged state, and then the end of the transmission shaft 72 located in the water storage box 111 drives the axial flow impeller 74 to rotate, and then when the opening 112 of the water storage box 111 and the first water injection port 89 and the second water injection port 810 on the mounting groove 811 in the center of the first cutting disc 81 and the second cutting disc 82 are staggered, the water storage box 111 is only connected to the water filling pipe 93, so that the axial flow impeller 74 forms a negative pressure in the water storage box 111 to pump water, and then when the first water injection port 89 and the second water injection port 810 rotate respectively When it coincides with the opening 112, the water pumped in is sent into the first water inlet 89 and the second water inlet 810 by the gravity of the water itself and the centrifugal force of the axial flow impeller 74, and then, with the help of the centrifugal force of the rotation of the first water inlet 89 and the second water inlet 810, the water is added to the cutting port 84 and the smooth edges of the first water inlet 89 and the second water inlet 810 through the drainage groove 83 and the water injection groove 85 respectively, and then the water is directly applied to the cutting area in stages to achieve dust reduction and a wetting effect specifically for fiber debris and dust in the deep cutting area; thereby effectively solving the problem that the existing cutting equipment will generate a large amount of dust and fiber debris when cutting fiberglass pipes, and the traditional water spray dust reduction is too wasteful and inaccurate.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
