Description

Technical Field

[0001] The present invention relates to the technical field of pipe processing, and more specifically, to a fully automatic sealing device and processing technology for a steel wire mesh skeleton pipe. Background Art

[0002] The steel wire mesh skeleton pipe is a new type of steel skeleton plastic composite pipe after improvement. This new type of pipe uses high-strength plastic-coated steel wire mesh skeleton and thermoplastic polyethylene as raw materials. The steel wire winding mesh is used as the skeleton reinforcement of the polyethylene plastic pipe. High-performance HDPE modified bonding resin is used to tightly connect the steel wire skeleton with the inner and outer layers of high-density polyethylene, making it have excellent composite effects. Because the high-strength steel wire reinforcement is coated in the continuous thermoplastic plastic, this composite pipe overcomes the respective disadvantages of steel pipes and plastic pipes, while maintaining the respective advantages of steel pipes and plastic pipes.

[0003] During the production process of the steel wire mesh skeleton pipe, the steel wires are exposed to the air after being cut at both ends. They will rust during storage or use, and the rusted steel wires will affect the pipe quality and even pose a risk of pipe explosion. Therefore, after extruding the steel wire mesh skeleton pipe, it is necessary to seal the end faces. In the prior art, there are mainly three methods for sealing the steel wires at both ends of the pipe: manually welding a sealing ring, injecting glue, or milling the end face steel wires and then melting the glue for sealing. These three sealing methods all have some disadvantages. For example, in the method of using a sealing ring: it is basically manual operation, the worker's labor intensity is high, the burrs need to be manually milled after sealing, which has a great impact on the on-site environment, and the cost of the sealing ring needs to be increased; in the method of injecting glue: it is necessary to add end face sealing injection materials, increasing the cost of auxiliary materials; in the method of milling the end face steel wires and then melting the glue for sealing: waste chips are generated during the milling process, affecting the on-site environment.

[0004] Therefore, designing a fully automatic sealing device and processing technology for a steel wire mesh skeleton pipe, which does not require manual operation, does not require adding auxiliary materials to increase additional costs, and does not require milling and will not affect the on-site environment, has become the direction of further improvement.

[0036] A positioning mechanism 5 is provided on one side of the glue melting and forming mechanism 4. Specifically, the positioning mechanism 5 includes an alignment cylinder 28, an alignment push plate 29, a lower positioning seat 30, a glue melting feed sensor 31, an upper pressing seat 32, and an upper pressing cylinder 33. The alignment cylinder 28 is fixedly installed on the outer side of the frame assembly 3, and the output end of the alignment cylinder 28 is connected to the alignment push plate 29; the lower positioning seat 30 is fixedly installed on the frame assembly 3, a glue melting feed sensor 31 is provided on one side of the lower positioning seat 30, the upper pressing seat 32 is vertically arranged above the lower positioning seat 30, and the upper end of the upper pressing seat 32 is adaptively connected to the upper pressing cylinder 33. The upper pressing cylinder 33 is fixedly installed at the upper end of the frame assembly 3.

[0037] At least one set of pipe transfer mechanism 6 is slidably provided between the frame assemblies 3. In the drawings of the present invention, two sets of pipe transfer mechanisms 6 are taken as an example for illustration. The pipe transfer mechanism 6 includes a pipe transfer frame 7, a feeding inclined rod 8, a slider connecting plate 9, a jacking assembly 10, a pipe transfer plate 11, a discharging inclined plate 12, a support positioning plate 13, and a turning rod 14. Pulleys 49 are provided at the bottom of the pipe transfer frame, and the pulleys 49 can slide on the slide rail 1. Feeding inclined rods 8 are relatively arranged on one side of the upper end of the pipe transfer frame 7. Figures 2 to 3As shown in the figure, the feeding diagonal rod 8 is composed of two staggered sections arranged at an obtuse angle. A feeding tube sensor 15 is attached to the back side of the feeding diagonal rod 8. A slider connecting plate 9 is arranged between the feeding diagonal rods 8. The bottom of the slider connecting plate 9 is slidably connected to the pipe transfer rack 7. A pipe transfer plate 11 is movably penetrated through the slider connecting plate 9 by a lifting assembly 10.

On the other side of the upper end of the pipe transfer rack 7, a turning rod 14 is movably arranged.

[0038] A mounting plate 24 is fixedly installed in the middle of the upper end of the pipe transfer rack 7. Three mounting holes are arranged side by side on the mounting plate 24. Second shaft sleeves 25 are fixedly installed in the mounting holes at both ends. A second positioning rod 26 is slidably installed in the second shaft sleeve 25.

[0039] The output shaft of a discharging air cylinder 27 is movably penetrated through the middle mounting hole. The upper end of the output shaft of the discharging air cylinder 27 is fixedly connected to the middle part of the discharging inclined plate 12. The lower end of the discharging air cylinder 27 is fixedly arranged at the lower end of the pipe transfer rack 7. The height of the discharging inclined plate 12 is slightly lower than the height of the supporting and positioning plate 13 to prevent the steel wire mesh skeleton pipe from being blocked during the sealing process. Only when the steel wire mesh skeleton pipe is sealed, the discharging air cylinder 27 jacks up, and at this time, the height of the discharging inclined plate 12 is higher than the height of the supporting and positioning plate 13, and the steel wire mesh skeleton pipe can smoothly roll down along the discharging inclined plate 12 to the area of the turning rod 14.

[0040] A turning air cylinder 16 is fixedly and obliquely arranged on the pipe transfer rack 7. The output end of the turning air cylinder 16 is connected to the bottom of the turning rod 14 through a turning joint 17. One end of the turning rod 14 is rotatably connected to the pipe transfer rack 7 through a hinge 18. A pipe transfer air cylinder 19 is fixedly installed inside the pipe transfer rack 7. The output end of the pipe transfer air cylinder 19 is connected to the middle of the bottom of the slider connecting plate 9 through a pipe transfer joint 20. In this embodiment, both the pipe transfer joint 20 and the turning joint 17 are I-shaped joints, which is convenient for receiving the steel wire mesh skeleton pushed by the turning rod 14 and then pushing the turning rod 14 by the turning air cylinder 16 to move the completed steel wire mesh skeleton pipe out of this equipment.

[0041] The lifting assembly 10 includes a lifting air cylinder 21, a first shaft sleeve 22, and a first positioning rod 23. Three through holes are arranged side by side on the slider connecting plate 9. First shaft sleeves 22 are fixedly installed in the through holes at both ends. A first positioning rod 23 is slidably installed in the first shaft sleeve 22. The upper end of the first positioning rod 23 is fixedly connected to the end of the pipe transfer plate 11. The output shaft of the lifting air cylinder 21 is movably penetrated through the middle through hole. The upper end of the output shaft of the lifting air cylinder 21 is fixedly connected to the middle part of the pipe transfer plate 11, so as to control the movement path of the pipe transfer plate 11 and avoid transfer errors.

[0042] A processing technology of a full-automatic sealing equipment for steel wire mesh skeleton pipes includes the following steps:

[0043] S1. The steel wire mesh skeleton pipe rolls into the equipment along the feeding inclined rod 8. The pipe inlet sensor 15 senses the entry of the steel wire mesh skeleton pipe, and the pipe moving mechanism 6 and the positioning mechanism 5 work together to position and fix the steel wire mesh skeleton pipe.

[0044] Specifically, step S1 is as follows: The steel wire mesh skeleton pipe rolls down along the feeding inclined rod 8 to this equipment. After the pipe inlet sensor 15 senses the entry of the steel wire mesh skeleton pipe, the alignment cylinder 28 extends to push the alignment push plate 29 to roughly position the left and right ends of the steel wire mesh skeleton pipe. Then, the lifting cylinder 21 rises upward to lift the steel wire mesh skeleton pipe. After the lifting cylinder 21 reaches the lifting position, the pipe moving cylinder 19 pulls the slider connecting plate 9 and drives the lifted steel wire mesh skeleton pipe into the support and positioning area. After reaching the position, the lifting cylinder 21 descends. At this time, the upper pressing cylinder 33 drives the upper pressing seat 32 to tightly press the steel wire mesh skeleton pipe onto the pressing block 48 in the lower positioning seat 30.

[0045] S2. Based on S1, the melt - glue forming mechanism 4 moves towards the positioned and fixed steel wire mesh skeleton pipe to perform melt - glue forming on both ends of the steel wire mesh skeleton pipe.

[0046] Specifically, step S2 is as follows: The servo - driven electric cylinder 35 moves to push the melt - glue forming mechanism 4 towards the steel wire mesh skeleton pipe. The end face of the steel wire mesh skeleton pipe enters the melt - glue forming mechanism 4 after being guided by the pipe inlet inner support ring 43 and the pipe inlet outer support ring 44. The end face of the steel wire mesh skeleton pipe contacts the melt - glue plate 37 and compresses the floating spring 47. When the servo - set torque is reached, the electric cylinder 35 stops moving and maintains this position for a certain period of time. The plastic on the end face of the steel wire mesh skeleton pipe melts through the heat of the heating plate 38. After reaching the preset time, the electric cylinder 35 drives the melt - glue forming mechanism 4 to retreat along the route of the melt - glue guide rail 41. After retreating to the set position, the forming cylinders 45 fixedly arranged at the upper and lower ends of the pipe inlet mounting frame 39 output simultaneously relative to each other, and the two forming dies 46 are closed in the middle of the pipe inlet mounting frame 39. After the forming dies 46 are closed, the electric cylinder 35 pushes the melt - glue forming mechanism 4 towards the steel wire mesh skeleton pipe, so that the end face of the steel wire mesh skeleton pipe is firmly pressed into the forming die 46 to form the end - face rubber material. When the set torque is reached, the electric cylinder 35 stops working and maintains this state until the preset pressure - holding time.

[0047] S3. Based on S2, after the melt - glue forming of the steel wire mesh skeleton pipe is completed and the time is up, the electric cylinder 35 then drives the melt - glue forming mechanism 4 to retreat along the route of the melt - glue guide rail 41 back to the origin.

[0048] S4. Based on S3, the pipe moving mechanism 6 moves the steel wire mesh skeleton pipe out of the processing area. Specifically, the discharging cylinder 27 jacks up, the steel wire mesh skeleton pipe rolls down along the discharging inclined plate 12 to the area of the turning rod 14, and then the turning cylinder 16 pushes the turning rod 14 to move the completed steel wire mesh skeleton pipe out of this equipment and turn it to the subsequent transfer trolley.

[0049] It should be explained that the slide rail 1, industrial control box 2, each cylinder, each sensor, and electric cylinder 35 used in the present invention are all common models that can be purchased on the market. The industrial control box 2 controls the sliding distance of the frame assembly 3, the extension or retraction of each cylinder, the induction of each sensor, the operation of the electric cylinder 35, and the processing time of the melting plate 37 and the heating plate 38. The control connection methods involved are also easily achievable by those skilled in the art in the prior art and are not the innovation points of the present invention. Therefore, the specific control connection methods are not marked in the figure and are not described in detail.

[0050] The overall equipment of the present invention is simple. After the two ends of the steel wire mesh skeleton pipe are cut, no additional auxiliary materials are required, and the self-fusing end face plastic is used to achieve the purpose of sealing, greatly reducing the use cost; the sealing and forming process is carried out by a fully automatic device, without waste chips generated, and does not affect the environment of the operation workshop; it saves labor costs, without manual intervention throughout the process, at least one post-production personnel can be saved for each production line, and it can be applicable to pipes of different diameters and lengths to achieve automatic sealing. Sealing and forming can be achieved without precise positioning, which is convenient to use and has good economic benefits.

[0051] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of the rights of the present invention. Therefore, modifications, equivalent changes, improvements, etc. made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
