Description

Technical Field

[0001] The present invention relates to the field of pipe fitting processing, and particularly to an auxiliary support device for the production of HDPE hollow outer rib spiral wound pipes. Background Art

[0002] The HDPE hollow outer rib spiral wound pipe is a kind of hollow wall wound pipe. The product is composed of plastic HDPE profiles spirally wound and bonded. The stiffness and ring flexibility of the HDPE hollow outer rib spiral wound pipe are relatively good.

[0003] Currently, in the process of winding the HDPE profile, the HDPE profile needs to be wound around once first, and then sleeved on the conveying roller. The rotation of the conveying roller makes the HDPE profile continue to wind, so that the HDPE profile is wound into a hollow spiral tube shape. During the winding process, the HDPE profile is bonded by an adhesive, and the HDPE profile needs to be supported before shaping. However, the traditional auxiliary support device usually uses support rollers for support, which is difficult to fully support the inside and outside of the wound HDPE profile, making the wound HDPE profile prone to collapse and deformation. In addition, the adhesive at the gaps of the HDPE profile is squeezed out during the winding process, making the adhesive at the gaps of the HDPE profile uneven, which is not convenient for assisting in bonding the HDPE profile. Moreover, the traditional auxiliary support device has the problem that the limitation of the HDPE profile is not sufficient, resulting in a poor winding effect. Summary of the Invention

[0004] The present invention aims to address the disadvantages of the traditional auxiliary support device, such as being difficult to fully support the inside and outside of the wound HDPE profile, the adhesive at the gaps of the HDPE profile being uneven, and the limitation of the HDPE profile being insufficient. Furthermore, an auxiliary support device for the production of HDPE hollow outer rib spiral wound pipes is provided, which can more fully support the inside of the wound HDPE profile, thus better shaping the HDPE profile, and can also make the adhesive more uniform and more fully limit the HDPE profile, better assisting in the winding of the HDPE.

[0014] 3. A number of semi-circular protrusions on the pressing ring sequentially squeeze the rubber ball, causing the swing bar to swing reciprocally.

Detailed implementation mode

[0027] The following is only a preferred embodiment of the present invention, and does not limit the protection scope of the present invention accordingly.

[0028] Embodiment 1: An auxiliary support device for producing HDPE hollow outer rib spiral wound pipes, as Figures 1 - 10 shown, comprising a support chassis 1, a servo motor 2, a rotating rod 3, a mounting bracket 4, a support rotating shaft 5, a driving assembly, a guiding and limiting assembly, and an adhesive extrusion assembly. A servo motor 2 is fixedly connected to the upper part of the support chassis 1. Two rotating rods 3 are rotatably connected to the upper part of the support chassis 1. The two rotating rods 3 are symmetrically arranged. A mounting bracket 4 is fixedly connected to the upper part of the support chassis 1. Five support rotating shafts 5 are rotatably connected to the mounting bracket 4. One of the support rotating shafts 5 located below is fixedly connected to the output shaft of the servo motor 2. A driving assembly is arranged on the support chassis 1. The driving assembly is connected to the support rotating shaft 5. A guiding and limiting assembly is arranged on the support chassis 1. An adhesive extrusion assembly is arranged on the guiding and limiting assembly. When the servo motor 2 is started, the support rotating shaft 5 is driven by the driving assembly to convey the HDPE profile 701, so that the HDPE profile 701 is wound into shape. The guiding and limiting assembly conducts more sufficient guiding and limiting on the HDPE profile. During the winding process, the adhesive extrusion assembly extrudes the adhesive at the gap of the HDPE profile, making the adhesive at the gap of the HDPE profile more uniform and better assisting the winding and shaping of the HDPE.

[0029] The driving component includes a support ring frame 61, a straight tooth ring 62 and a straight gear 63. The support bottom frame 1 is provided with a support ring frame 61 at the upper part. A straight tooth ring 62 is rotatably connected to the support ring frame 61. One end of each support rotating shaft 5 is provided with a straight gear 63. All five straight gears 63 are meshed with the straight tooth ring 62. When the servo motor 2 is started, it drives one of the straight gears 63 and one of the support rotating shafts 5 to rotate. One of the straight gears 63 drives the straight tooth ring 62 to rotate, and the straight tooth ring 62 drives the other four support rotating shafts 5 to rotate. The five support rotating shafts 5 rotate to wind and convey the HDPE profile 701.

[0030] The guiding and limiting component includes a support cylinder frame 71, a support block 72, guiding wheels 73, a fixing frame 74, limiting wheels 75 and a guiding frame 76. The support bottom frame 1 is provided with a support cylinder frame 71 at the upper part. A support block 72 is fixedly connected to the support cylinder frame 71. Two guiding wheels 73 are rotatably connected to the support block 72. The two guiding wheels 73 are symmetrically arranged. Six groups of fixing frames 74 are fixedly connected to the inner wall of the support cylinder frame 71. The number of each group of fixing frames 74 is seven. A limiting wheel 75 is rotatably connected to each fixing frame 74. A limiting groove is formed in each limiting wheel 75. Six guiding frames 76 are fixedly connected to the inner wall of the support cylinder frame 71. The six guiding frames 76 and the six groups of fixing frames 74 are arranged at intervals. A number of guiding grooves are formed on one side of the six guiding frames 76 close to each other. The HDPE profile 701 is placed between the six guiding frames 76 and the six groups of limiting wheels 75. During the process of winding the HDPE profile 701, the guiding grooves of the guiding frame 76 and the limiting grooves of the limiting wheels 75 can more fully limit the HDPE profile 701, so that the HDPE profile 701 can be wound better. One end of the HDPE profile 701 passes between the two guiding wheels 73 and passes through the support block 72. The two guiding wheels 73 guide the HDPE profile 701, and a number of support rotating shafts 5 are all in contact with the HDPE profile 701.

[0031] The adhesive extrusion component includes a large extrusion wheel 81, a mounting bracket 82, a support plate 83, a sliding frame 84, an extrusion spring 85 and a small extrusion wheel 86. Large extrusion wheels 81 are rotatably connected to one side of the two guiding frames 76 close to each other. The two large extrusion wheels 81 are symmetrically arranged. The two large extrusion wheels 81 are both in contact with the outer side of the HDPE profile 701. The two large extrusion wheels 81 can extrude and evenly apply the adhesive overflowing from the outer side of the HDPE profile 701. A mounting bracket 82 is fixedly connected to the lower part of the mounting frame 4. Two support plates 83 are fixedly connected to the mounting bracket 82. A sliding frame 84 is slidably connected to one side of each of the two support plates 83 away from each other. An extrusion spring 85 is connected between the sliding frame 84 and the support plate 83. Small extrusion wheels 86 are rotatably connected to one side of the two sliding frames 84 away from each other. The small extrusion wheels 86 are all in contact with the inner side of the HDPE profile 701. The small extrusion wheels 86 can extrude and evenly apply the adhesive overflowing from the inner side of the HDPE profile 701.

[0032] When the HDPE profile 701 needs to be wound into a tube, the worker passes one end of the HDPE profile 701 through the support block 72, then through between the two guide wheels 73, and then pushes the HDPE profile 701 to make the HDPE profile 701 contact one of the support rotating shafts 5. Then, the servo motor 2 is started. The servo motor 2 drives one of the support rotating shafts 5 located below and one of the spur gears 63 to rotate through the output shaft. One of the spur gears 63 drives the spur gear ring 62 to rotate, and the spur gear ring 62 drives the remaining spur gears 63 and support rotating shafts 5 to rotate, so that the five support rotating shafts 5 rotate simultaneously and push the HDPE profile 701, and the HDPE profile 701 can be conveyed. At the same time, the worker brushes the adhesive onto the HDPE profile 701. During the conveying process, the HDPE profile 701 will contact the limit groove of the limit wheel 75 and the guide groove of the guide frame 76. The limit groove of the limit wheel 75 and the guide groove of the guide frame 76 perform more sufficient limiting on the HDPE profile 701. The support rotating shaft 5 continuously conveys the HDPE profile 701, so that the HDPE profile 701 is wound into a hollow spiral tube shape between the limit groove of the limit wheel 75 and the guide groove of the guide frame 76. The adhesive bonds the HDPE profile 701. During the conveying process, the inner wall of the wound HDPE profile 701 contacts the small pressing wheel 86. Under the elastic force of the pressing spring 85, the small pressing wheel 86 presses the inner wall of the wound HDPE profile 701. At the same time, the outer wall of the wound HDPE profile 701 contacts the large pressing wheel 81, and the large pressing wheel 81 presses the outer wall of the wound HDPE profile 701. The inner and outer walls of the wound HDPE profile 701 are pressed simultaneously. The large pressing wheel 81 and the small pressing wheel 86 will take away the excess adhesive at the gap of the HDPE profile 701 and smear the excess adhesive onto the gap of the HDPE profile 701 where the adhesive is less, so that the adhesive at the gap of the wound HDPE profile 701 is more uniform, improving the winding effect of the HDPE profile 701. After the adhesive solidifies, the wound HDPE profile 701 is shaped. Then, the support rotating shaft 5 continues to convey the HDPE profile 701, so that the wound HDPE profile 701 contacts the two rotating rods 3, and the rotating rods 3 support the wound HDPE profile 701. When the HDPE profile 701 is wound to a certain length, the worker uses a tool to cut off the wound HDPE profile 701. After the winding is completed, the worker turns off the servo motor 2.

[0033] Example 2: On the basis of Example 1, as Figure 2 、 Figure 6 and Figure 11As shown in the figure, it further includes an internal support assembly. The internal support assembly is arranged on the support rotating shaft 5. The internal support assembly is connected to the support chassis 1. The internal support assembly includes a cam 91, a support rod 92, a support frame 93, an internal support frame 94, a return spring 95 and a circular frame 96. A cam 91 is fixedly connected to one end of each support rotating shaft 5 away from the spur gear 63. A support rod 92 is fixedly connected to the upper part of the support chassis 1. The support rod 92 passes through the mounting bracket 82. A support frame 93 is fixedly connected to the support rod 92. Five internal support frames 94 are slidably connected to the support frame 93. The cam 91 contacts the internal support frame 94. When the cam 91 rotates, it will intermittently squeeze the internal support frame 94, causing the internal support frame 94 to intermittently open, so that the internal support frame 94 can more fully support the inside of the HDPE profile 701. A return spring 95 is connected between each internal support frame 94 and the support frame 93. A circular frame 96 is fixedly connected to one end of the support rod 92 close to the support frame 93.

[0034] When the support rotating shaft 5 rotates, it will drive the cam 91 to rotate. The cam 91 will intermittently squeeze the internal support frame 94, causing the five internal support frames 94 to move away from each other. When the cam 91 continues to rotate and no longer squeezes the internal support frame 94, the return spring 95 resets and drives the internal support frame 94 to reset. In this way, the five internal support frames 94 expand and contract reciprocally, so that the five internal support frames 94 intermittently support the inside of the wound HDPE profile 701 more fully, which can further shape the wound HDPE profile 701 and make the wound HDPE profile 701 better maintain its shape.

[0035] Embodiment 3: On the basis of Embodiment 2, as Figure 5 and Figure 7As shown in the figure, it further includes a pressing component. The pressing component is arranged on one of the support rotating shafts 5. The pressing component is connected to the mounting frame 4. The pressing component includes a pressing ring 101, a fixed bracket 102, a limiting strip 103, a swinging strip 104, a spring piece 105, a pressing roller 106, a pressing rod 107 and a rubber ball 108. A pressing ring 101 is arranged on one of the support rotating shafts 5 located above. A fixed bracket 102 is fixedly connected to the top of the mounting frame 4. A limiting strip 103 is fixedly connected to the fixed bracket 102. A swinging strip 104 is rotatably connected to the limiting strip 103. A spring piece 105 is connected between the swinging strip 104 and the limiting strip 103. Five pressing rollers 106 are rotatably connected to one side of the swinging strip 104 away from the fixed bracket 102. Four pressing rollers 106 are rotatably connected to one side of the limiting strip 103 away from the fixed bracket 102. A number of pressing rollers 106 are all in contact with the side of the HDPE profile 701. A pressing rod 107 is fixedly connected to the swinging strip 104. A rubber ball 108 is arranged at one end of the pressing rod 107 away from the swinging strip 104. A number of semi-circular protrusions are arranged on one side of the pressing ring 101 close to the swinging strip 104. The rubber ball 108 will sequentially contact a number of semi-circular protrusions on the pressing ring 101. The rotation of the pressing ring 101 will cause a number of semi-circular protrusions to sequentially press the rubber ball 108, causing the rubber ball 108, the pressing rod 107 and the swinging strip 104 to swing intermittently. The swinging strip 104 and the pressing rollers 106 on the swinging strip 104 will intermittently press the side of the HDPE profile 701, making the HDPE profile 701 wind more tightly.

[0036] One of the support rotating shafts 5 located above rotates to drive the pressing ring 101 to rotate. A number of semi-circular protrusions on the pressing ring 101 sequentially press the rubber ball 108. A number of semi-circular protrusions on the pressing ring 101 press the rubber ball 108, the pressing rod 107 and the swinging strip 104 to swing. When a number of semi-circular protrusions on the pressing ring 101 are separated from the rubber ball 108, the spring piece 105 drives the swinging strip 104, the pressing rod 107 and the rubber ball 108 to reset. In this way, the swinging strip 104 swings reciprocally. The pressing rollers 106 on the swinging strip 104 will press the wound HDPE profile 701, making the HDPE profile 701 wind more tightly and further better assisting in HDPE winding.

[0037] Embodiment 4: On the basis of Embodiment 3, as Figure 3 、 Figure 6 and Figure 8 shown, it further includes a top frame 111 and a scraper 112. A top frame 111 is fixedly connected to the top of the mounting frame 4. A scraper 112 is fixedly connected to the top frame 111. The scraper 112 is in contact with the HDPE profile 701.

[0038] During the winding process of the HDPE profile 701, the scraper 112 will scrape off the excess burrs on the side of the HDPE profile 701 and can smooth the side of the HDPE profile 701, making the winding of the HDPE profile 701 more flat and improving the winding effect.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
