Description

Technical Field

[0001] The invention relates to the technical field of pipe sealing, in particular to a wire mesh pipe sealing device. Background Art

[0002] Wire mesh pipe is an industry name for wire mesh plastic composite pipe, which is a new type of improved steel skeleton plastic composite pipe. This pipe is made of plasticized high-strength steel wire cross-woven into a mesh as the skeleton and thermoplastic polyethylene. The steel wire winding mesh is used as the skeleton reinforcement of the polyethylene plastic pipe, and high-density polyethylene (HDPE) is used as the core tube matrix. High-performance HDPE modified adhesive resin is used to tightly connect the steel wire skeleton with the inner and outer layers of high-density polyethylene, so that it has an excellent composite effect.

[0003] like Figure 1 As shown, the wire mesh pipe 10 includes a plastic inner layer 12, a wire mesh frame 11 and a plastic outer layer 13 which are sequentially distributed from the inside to the outside. Due to the existence of the wire mesh frame 11, the cut portion (i.e., the end face of the wire mesh pipe 10) needs to be sealed after cutting to prevent fluid and dust from entering between the wire mesh frames 11 and to prevent the wire mesh frame 11 from oxidizing and rusting and causing the pipe to delaminate. At present, the plastic ring butt welding sealing technology is commonly used to utilize the plastic ring and the pipe end face to be hot-melted butt-jointed. The specific sealing process is as follows: first, the end face of the wire mesh pipe is polished. After the end face is flattened, the oxide scale is removed, and then the pipe end face and the plastic ring are placed on both sides of the heating mold and hot-melted at the same time. After that, the plastic ring is immediately removed and crimped onto the pipe end face. Finally, the welding part is trimmed to complete the sealing of the wire mesh pipe. However, in the existing production process, the above sealing process is mostly carried out manually, the sealing quality is difficult to guarantee, and the automation level is low, resulting in low sealing efficiency. In view of this, we propose a wire mesh pipe sealing device. Summary of the invention

[0057] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0058] The present invention provides a wire mesh pipe sealing device, which is easy to operate, has a high degree of automation, and a high sealing efficiency, can greatly improve the sealing qualification rate, and only uses the material of the pipe itself for sealing, without the need for auxiliary materials for auxiliary sealing, thereby greatly saving costs.

[0059] Please refer to Figures 2 to 5 The present embodiment provides a wire mesh tube sealing device, which includes a sealing mechanism 20 and a slotting mechanism 30. The slotting mechanism 30 is used to process the end surface of the wire mesh tube 10 and form a sealing groove 10b with a plastic outer layer and a plastic inner layer as groove walls. The sealing groove 10b is an annular groove with the same center as the wire mesh tube. The sealing mechanism 20 includes a sleeve 21, a heating plate 22, an end plate 23 and a power assembly.

[0060] Specifically, the sleeve 21 has a first port and a second port relative to each other, and a receiving cavity 21a is provided inside the sleeve 21, which passes through the first port and the second port. The heating disc 22 is embedded in the first port and partially extends into the receiving cavity 21a. A heating groove 22a is provided at one end of the heating disc 22 located in the receiving cavity 21a, and the heating groove 22a is used to connect with the sealing groove 10b. The end plate 23 is installed at the second port and is provided with an opening connected to the receiving cavity 21a. A plurality of clamping blocks 29 are distributed in the opening at intervals around the center of the opening, and the plurality of clamping blocks 29 cooperate to clamp the wire mesh pipe 10. The power assembly is used to drive the heating disc 22 to move along the axial direction of the sleeve 21 to apply an extrusion force to the sealing groove 10b.

[0061] The present application processes the end surface of the wire mesh tube 10 by using a slotting mechanism to form a sealing groove 10b with a plastic outer layer and a plastic inner layer as groove walls, and then extends one end of the wire mesh tube formed with the sealing groove 10b from the second port into the accommodating cavity 21a and abuts against the surface of the heating plate 22 located in the accommodating cavity 21a. At this time, the sealing groove 10b is inserted into the heating groove 22a, and then the power component is used to drive the heating plate 22 along the sleeve 21a. The heating plate 22 moves axially so that the heating plate 22 applies an extrusion force to the end of the steel wire mesh tube 10 with the sealing groove 10b, ensuring that the plastics on the two groove walls of the sealing groove 10b are wrapped by the heating groove 22a. At this time, under the heating effect of the heating plate 22, the plastic materials on both sides of the sealing groove 10b flow to the middle of the sealing groove 10b in a molten state, and after cooling, the steel wire mesh located in the sealing groove 10b is coated, thereby completing the sealing of the steel wire mesh tube 10. The device is easy to operate and has a high sealing qualification rate, which can greatly improve the sealing qualification rate, and only uses the material of the tube itself for sealing, without the need to use auxiliary materials for auxiliary sealing, which greatly saves costs.

[0062] In addition, after one end of the wire mesh tube 10 with the sealing groove 10b is inserted into the open end plate 23 and abutted against the heating plate 22, the clamping block 29 is adjusted to continuously approach the center of the end plate 23 until multiple clamping blocks 29 abut against the outer surface of the wire mesh tube 10, thereby clamping and fixing the wire mesh tube 10 to avoid loosening during the sealing process and affecting the sealing quality.

[0063] In actual use, Figure 6As shown, the sealing groove 10b at the end face of the steel wire mesh pipe 10 is V-shaped, and when the sealing groove 10b is inserted into the heating groove 22a, the groove top of the sealing groove 10b abuts against the groove bottom of the heating groove 22a. At this time, the steel wire is located in the sealing groove 10b, and the outer surface of the steel wire is abutted by the groove side wall of the sealing groove 10b. In other words, the steel wire completely falls into the sealing groove 10b, and when the heating plate 22 is turned on for heating, the heat will be transferred to the heating groove 22a, and then the groove side wall of the sealing groove 10b will be heated to form a molten state and flow to the center of the sealing groove 10b, thereby completely covering the steel wire.

[0064] For example, the two opposite ends of the sleeve 21 are defined as the first port and the second port respectively for the purpose of describing the direction in which the heating plate 22, the end plate 23 and the steel wire mesh tube 10 extend, and do not serve as a limitation. In other words, the heating plate 22 is installed at one end of the sleeve 21 as the first port, and the other end as the second port, which depends on the relative position of the heating plate 22.

[0065] Since one end of the wire mesh pipe 10 to be sealed extends into the accommodating cavity 21a and abuts against the heating plate 22, and when the sealing groove 10b is inserted into the heating groove 22a, the bottom surface of the heating groove 22a and the top surface of the sealing groove 10b may not be tightly abutted, which may easily lead to incomplete covering of the steel wire and cause poor sealing effect. In this regard, in this embodiment, the power component is used to drive the heating plate 22 to move only along the axial direction of the sleeve 21, and does not rotate relative to the rotating drum 251, that is: when the end of the wire mesh tube 10 to be sealed abuts against the heating plate 22, the power component is used to drive the heating plate 22 to approach the wire mesh tube 10 until the bottom surface of the heating groove 22a is tightly abutted against the top surface of the sealing groove 10b, ensuring that after the heating plate 22 heats the two groove walls of the sealing groove 10b, the plastic glue on both sides of the sealing groove 10b flows toward the center thereof, thereby completely covering the steel wire located in the sealing groove 10b, and achieving a better sealing effect.

[0066] Here, it should be noted that the heating disc 22 is driven to move only along the axial direction of the sleeve 21, which means that the heating disc 22 can be close to or away from the wire mesh tube 10, and the circumferential rotation of the heating disc 22 along the sleeve 21 is limited by an auxiliary workpiece, which can be achieved by the following structure, for example:

[0067] like Figure 7As shown, the sealing mechanism 20 further includes a pin block 210, the end surface of the sleeve 21 provided with the first port is provided with a first pin groove 10a, the outer circumference of the heating disc 22 is provided with a second pin groove 22e corresponding to the first pin groove 10a, the second pin groove 22e cooperates with the first pin groove 10a to form a pin hole, and the pin block 210 is inserted into the pin hole to limit the rotation of the heating disc 22. That is to say, after extending one end of the heating disc 22 provided with the heating groove 22a from the first port into the accommodating cavity 21a, and aligning the second pin groove 22e with the first pin groove 10a to form a pin hole, the pin block 210 is then inserted into the corresponding pin hole, so that the circumferential rotation of the heating disc 22 along the sleeve 21 is limited, and the heating disc 22 can only move along the axial direction of the sleeve 21.

[0068] In addition, the connection method for the power component to drive the heating plate 22 to move along the axial direction of the sleeve 21 can adopt the conventional connection in the prior art, or can adopt the following connection structure, which is not limited.

[0069] Please refer to Figure 4 and Figure 8 In one embodiment, the power assembly includes a toothed disc 26 and a power member 24. The toothed disc 26 is rotatably disposed in the accommodating cavity. The toothed disc 26 is provided with a through hole communicating with the accommodating cavity 21a. The hole wall of the through hole is provided with a first transmission part 26b. The portion of the heating disc 22 located in the accommodating cavity 21a and extending into the through hole is provided with a second transmission part 22b. The second transmission part 22b is connected to the first transmission part 26b in a transmission manner to drive the heating disc 22 to move along the axial direction of the sleeve 21. The power member 24 is used to drive the toothed disc 26 to rotate along the circumferential direction of the sleeve 21. In this embodiment, the power member 24 is mounted on the outer surface of the sleeve 21, and the power member 24 can be a combination of a motor and a gearbox, but is not limited thereto.

[0070] In this embodiment, the heating disc 22 is partially extended into the accommodating chamber 21a and is extended into the through hole, and the second transmission part 22b is used to perform transmission connection with the first transmission part 26b, so that the toothed disc 26 can rotate relative to the heating disc 22, that is, when the power member 24 drives the toothed disc 26 to rotate, the toothed disc 26 rotates relative to the heating disc 22, and then the heating disc 22 can be driven to move along the axial direction of the sleeve 21 until the bottom surface of the heating groove 22a is tightly abutted against the top surface of the sealing groove 10b. In other words, the power member 24 is used to drive the rotation of the toothed disc 26 to provide the required power, and the transmission connection between the power member 24 and the toothed disc 26 can be a gear transmission method, or other transmission methods that can drive the toothed disc 26 to rotate in the accommodating chamber, which is not limited to this.

[0071] In addition, the first transmission part 26b and the second transmission part 22b can both be transmission threads, that is, a first transmission thread is arranged on the part of the heating plate 22 extending into the accommodating cavity 21a, and a corresponding second transmission thread is arranged on the hole wall of the through hole, so that the part of the heating plate 22 extending into the through hole realizes transmission connection by means of the first transmission thread and the second transmission thread cooperating with each other.

[0072] Reference Figure 8 Specifically, the power assembly also includes a plurality of adjusting teeth 27, which are embedded in the sleeve 21 along the circumferential intervals of the sleeve 21, and a first gear 26a is provided along the outer circumference of the toothed disc 26 at one end close to the adjusting teeth 27, and the adjusting teeth 27 are meshed with the first gear 26a, and the output end of the power member 24 is connected to at least one adjusting tooth 27 by transmission. In other words, a plurality of adjusting teeth 27 are embedded along the circumferential intervals of the sleeve 21 at one side close to the toothed disc 26, and the first gear 26a is meshed with the adjusting teeth 27. Since the output end of the power member 24 is connected to at least one adjusting tooth 27 by transmission, when the power member 24 drives the adjusting teeth 27 to rotate, the toothed disc 26 is driven to rotate, and then the heating disc 22 is driven to move along the axial direction of the sleeve 21 to apply an extrusion force to the sealing groove 10b. It should be noted that the first gear adopts a conical tooth, and correspondingly, the tooth portion of the adjusting tooth is also a conical tooth.

[0073] Before sealing the end face of the wire mesh tube 10, the tube needs to be descaled. Currently, the scale of the tube is removed manually using a peeling tool to facilitate subsequent sealing operations. However, the manual descaling method has poor descaling effect, high labor intensity, and a long time consumption, which leads to low sealing efficiency.

[0074] Please refer to Figure 5 and Figure 8In this regard, in one embodiment, the sealing mechanism 20 further includes a peeling assembly 25, which includes a rotating drum 251, a rotating ring 252, and a plurality of first blades 253. The rotating drum 251 is rotatably disposed in the accommodating cavity and is located between the end plate 23 and the toothed disc 26. The interior of the rotating drum 251 is provided with a cavity communicating with the opening and the through hole, and the end of the rotating drum 251 close to the toothed disc 26 is provided with a second gear 251a along the outer periphery of the rotating drum 251. The output end of the power member 24 is connected with a driving gear 28, which meshes with the second gear 251a to drive the rotating drum 251 to rotate along the circumference of the sleeve 21. The rotating ring 252 is disposed in the cavity, and the outer surface of the rotating ring 252 is provided with a third transmission part 252a, and the inner wall of the rotating drum 251 is provided with a fourth transmission part 251b, which is transmission-connected with the third transmission part 252a to drive the rotating ring 252 to move along the axial direction of the sleeve 21. A plurality of first cutting heads 253 are distributed on the inner wall of the rotating ring 252 around the center of the rotating ring 252 , and are used to cut the plastic outer layer of the wire mesh tube 10 .

[0075] For example, when sealing the steel wire mesh tube 10, one end of the tube provided with the sealing groove 10b is extended from the open end into the accommodating cavity 21a and pushed toward the first port so that the end face of the tube abuts against the heating plate 22. Then, the clamping block 29 is adjusted to continuously approach the center of the end plate 23 to clamp the tube. Then, the power member 24 is turned on to drive the active gear 28 to rotate, thereby driving the rotating drum 251 to rotate in the accommodating cavity. Since the rotating ring 252 is located on the rotating drum 251, the rotating ring 252 is located on the rotating drum 251. The swivel 252 is driven to rotate, and then the swivel 252 moves along the axial direction of the sleeve 21. During this process, a plurality of first cutter heads 253 installed on the inner wall of the swivel 252 cut the plastic outer layer 13 of the wire mesh pipe 10, thereby automatically removing the oxide layer of the plastic outer layer without manual cutting, reducing labor intensity and facilitating improving subsequent sealing efficiency.

[0076] Specifically, the third transmission part 252a and the fourth transmission part 251b can both use transmission threads, that is, a fourth transmission thread is provided on the inner wall of the rotating cylinder 251, and a third transmission thread that is compatible with the fourth transmission thread is correspondingly provided on the outer surface of the rotating ring 252, so that when the toothed disk 26 is driven to rotate, the rotating ring 252 realizes a rolling connection by matching the third transmission thread with the fourth transmission thread.

[0077] Please refer to Figure 7In one embodiment, a cooling cavity is provided inside the heating plate 22, and the cooling cavity is used to cool the heating plate 22. The heating plate 22 is provided with a liquid inlet 22c and a liquid outlet 22d connected to the cooling cavity. In this way, when the heating plate 22 heats the end surface of the steel wire mesh tube 10 to a predetermined time, the heating source of the heating plate 22 is disconnected, and one end of the cooling water pipe is plugged into the liquid inlet 22c, and one end of the water outlet pipe is plugged into the liquid outlet 22d, so that the cooling water is passed into the cooling cavity in a circulating manner, and then the heat in the heating plate 22 can be quickly taken away, and rapid cooling and temperature reduction can be achieved, thereby accelerating the cooling and forming of the end surface of the steel wire mesh tube 10.

[0078] Please refer to Figure 7 Since the sealing grooves 10b of different sizes need to use the heating grooves 22a of corresponding sizes, the required heating discs 22 need to be replaced according to the pipes of different diameters. In this regard, in one embodiment, a handle 211 is provided on the surface of the heating disc 22 away from the end plate 23 to facilitate the rapid replacement of the heating disc 22. For example, when the corresponding heating disc 22 needs to be replaced, it is only necessary to hold the handle 211 and pull the heating disc 22 away from the end plate 23 to achieve rapid replacement.

[0079] Please refer to Fig. 9 In one embodiment, the slotting mechanism 30 includes a rotating disk 31 and a driving member 33. The rotating disk 31 has a first surface 31a and a second surface 31b opposite to each other. The first surface 31a is provided with a plurality of second cutter heads 32, and the plurality of second cutter heads 32 are distributed around the center of the rotating disk 31 at intervals. The output end of the driving member 33 is connected to the second surface 31b, and is used to drive the rotating disk 31 to rotate, so as to drive the second cutter head 32 to rotate and process the wire mesh frame at the end face of the wire mesh frame tube 10 to form a sealing groove. That is to say, when processing the wire mesh frame at the end face of the wire mesh frame tube 10, the second cutter head 32 is aligned with the position where the wire mesh frame tube 10 end face needs to be slotted, and the toothed disk 26 is driven to rotate by the driving member 33 to drive the second cutter head 32 installed on the rotating disk 31 to rotate, thereby completing the processing of the wire mesh frame at the end face of the wire mesh frame tube 10 to form a sealing groove 10b. The slotting mechanism 30 is easy to operate, has high slotting efficiency, and is conducive to accelerating the sealing efficiency. It should be noted that the first surface 31 a is the surface of the rotating disk 31 facing the end surface of the wire mesh tube 10 , and the second surface 31 b is the surface of the rotating disk 31 facing away from the end surface of the wire mesh tube 10 .

[0080] Furthermore, a plurality of mounting holes are provided on the first surface 31a, and the plurality of mounting holes are spaced around the center of the rotating disk 31, and the second blade head 32 is inserted into the mounting holes, so that the second blade head 32 can be detachably mounted on the rotating disk 31. In other words, when there is a need for sealing grooves 10b of different calibers, the second blade heads 32 of different sizes can be replaced, without replacing the rotating disk 31 and the second blade head 32 as a whole.

[0081] During the grooving process, workers need to constantly monitor the grooving process, and grinding debris can easily splash, which can cause certain dangers. Fig.10 The slotting mechanism 30 further includes a retaining ring 34, which is covered on the outer periphery of the rotating disk 31 and cooperates with the first surface 31a of the rotating disk 31 to form a processing cavity 35 with an opening. That is, when the end face of the wire mesh tube 10 is slotted, the end face of the wire mesh tube 10 extends into the processing cavity 35, and the retaining ring 34 can effectively block the flying debris to prevent it from splashing onto the worker's face or eyes, which can play a protective role. In addition, an observation hole 34a is provided on the retaining ring 34 so that the worker can observe the slotting through the observation hole 34a.

[0082] Furthermore, the slotting mechanism 30 further includes a plurality of clamping blocks 36, which are spaced around the center of the rotating disk 31 and are distributed in the processing cavity 35, and the plurality of clamping blocks 36 cooperate to clamp the wire mesh tube 10. That is, after the end face of the wire mesh tube 10 is inserted into the processing cavity 35, the plurality of clamping blocks 36 are adjusted so that they are constantly close to the wire mesh tube 10 until they are in contact with the outer surface of the wire mesh tube 10, so that the wire mesh tube 10 can be clamped, thereby avoiding shaking during the slotting process and affecting the quality of the slotting.

[0083] Please refer to Fig.11 and Fig.12Since the steel wire mesh tube 10 is easily squeezed and dented during transportation or transfer, when the end surface of the steel wire mesh tube 10 is processed, the sealing groove formed is uneven, which affects the sealing quality. In this regard, in one embodiment, the steel wire mesh tube 10 sealing device also includes a support mechanism 40, and the support mechanism 40 includes a support rod 41 and a locking column 46. A sliding sleeve 42 is slidably connected to the rod body of the support rod 41, and a plurality of first rod bodies 43 extend outward from the outer periphery of the sliding sleeve 42. The support rod 41 extends into one end of the steel wire mesh tube 10, and a plurality of second rod bodies 44 are movably connected along the circumference of the support rod 41, and the plurality of second rod bodies 44 correspond to the plurality of first rod bodies 43 one by one; the locking column 46 is telescopically arranged on the sliding sleeve 42, and the locking column 46 passes through one end of the sliding sleeve 42 for contacting with the support rod 41 to lock the sliding sleeve 42 on the support rod 41. Among them, one end of the first rod body 43 close to the sliding sleeve 42 is rotatably connected to the sliding sleeve 42, one end of the second rod body 44 close to the support rod 41 is rotatably connected to the support rod 41, and one end of the second rod body 44 away from the support rod 41 is rotatably connected to a support block 45, and the support block 45 is used to abut against the inner wall of the wire mesh tube 10, and one end of the first rod body 43 away from the sliding sleeve 42 is rotatably connected to the second rod body 44.

[0084] For example, before the end surface of the wire mesh tube 10 is grooved, the sliding sleeve 42 is first moved to drive the first rod 43 to slide, so that the second rod 44 is pulled inwardly to retract, thereby driving the support block 45 to retract inwardly, and then the entire support mechanism 40 is extended into the interior of the wire mesh tube 10. At this time, the support block 45 does not contact the inner wall of the wire mesh tube 10, and then the support rod 41 is driven to rotate, so that the sliding sleeve 42 is pushed to extend into the inner wall of the wire mesh tube 10. One end of the wire mesh tube 10 slides, thereby driving the first rod 43 to push the second rod 44 outward, thereby pushing the support block 45 to continuously approach the inner wall of the wire mesh tube 10, until the support block 45 is close to the inner wall of the wire mesh tube 10 and the support rod 41 cannot be rotated, indicating that the support is in place. At this time, tightening the lock column 46 can complete the support of the wire mesh tube 10, avoiding the collapse of the wire mesh tube 10 and causing poor grooving effect. In addition, in this embodiment, the above-mentioned rotating connection can be specifically hinged, but is not limited to this.

[0085] In one embodiment, the support block 45 is made of plastic material. Specifically, the plastic material can be rubber, so that after the support block 45 abuts against the inner wall of the wire mesh tube 10, it can effectively prevent the inner wall of the wire mesh tube 10 from being scratched.

[0086] In one embodiment, the end surface of the support block 45 that contacts the inner wall of the wire mesh tube 10 is arc-shaped. That is, when the support block 45 contacts the inner wall of the wire mesh tube 10, the arc-shaped end surface of the support block 45 will be close to the arc-shaped inner wall surface of the wire mesh tube 10, which has a better supporting effect.

[0087] In one embodiment, the support rod 41 is provided with anti-skid grooves 41a on the rod body at one end away from the second rod body 44, so that workers can increase friction when holding it, facilitate operation, and effectively prevent slipping and inability to operate.

[0088] The working process of the present invention is:

[0089] The entire support mechanism 40 is extended into the interior of the wire mesh tube 10, and the support rod 41 is driven to rotate, so that the sliding sleeve 42 is pushed to slide toward the end extending into the wire mesh tube 10, thereby driving the first rod body 43 to push the second rod body 44 outward, so as to push the support block 45 to continuously approach the inner wall of the wire mesh tube 10, until the support block 45 is close to the inner wall of the wire mesh tube 10 and the support rod 41 cannot be rotated, indicating that the support is in place, and at this time, the lock column 46 is tightened to complete the support function of the wire mesh tube 10;

[0090] The second cutter head 32 is aligned with the position where the end surface of the wire mesh tube 10 needs to be grooved, and the toothed disc 26 is driven to rotate by the driving member 33 to drive the second cutter head 32 installed on the rotating disc 31 to rotate, so as to process the wire mesh at the end surface of the wire mesh tube 10 to form a sealing groove 10b;

[0091] One end of the steel wire mesh pipe 10 with the sealing groove 10b is extended from the second port into the accommodating cavity and abuts against the surface of the heating plate 22 in the accommodating cavity. At this time, the sealing groove 10b is inserted into the heating groove 22a, and then the power component is used to drive the heating plate 22 to move along the axial direction of the sleeve 21, so that the heating plate 22 applies an extrusion force to the end of the steel wire mesh pipe 10 with the sealing groove 10b, ensuring that the plastic on both sides of the sealing groove 10b is wrapped by the heating groove 22a. At this time, under the heating action of the heating plate 22, the plastic material on both sides of the sealing groove 10b forms a molten state and flows to the middle thereof. After cooling, the steel wire in the sealing groove 10b is coated, thereby completing the sealing of the steel wire mesh pipe 10.

[0092] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
