Description

Technical Field

[0001] The invention relates to the technical field of spiral winding of profiles, and in particular to a full-motion rolling spiral winding pipe forming machine. Background Art

[0002] Most of the existing urban underground sewage pipes are made of prefabricated cement pipes, but due to their large size and heavy weight, as domestic cities age, cement pipes under cities are affected by corrosion and changes in geological conditions. Many pipes have leakage problems but are difficult to repair. In the prior art, municipal pipes, especially large municipal pipes, mainly use cast iron pipes, cement pipes, etc. These pipes require large molds when they are made, and the transportation of products is very difficult. There are also defects such as poor acid and alkali corrosion resistance. With the vigorous promotion of urbanization construction, technological innovations in the field of water supply and drainage are also changing with each passing day. Cement pipes are gradually being replaced by spiral plastic pipes that are lightweight and have a long life.

[0003] In the prior art forming machine, when the spiral tube is wound and formed, the plate is clamped by the driving roller and the surrounding sleeve, driving the plate to rotate forward in a spiral shape, thereby forming a spiral tube. Therefore, during the spiral forming, the plate moves in the circumferential direction and the axial direction at the same time. Since the driving roller drives the plate to rotate, the gap between the driving roller and the surrounding sleeve is required to fix the plate, which applies a large pressure to the plate, making it very difficult for the plate to move in the axial direction, and will encounter a large resistance, resulting in low forming efficiency, affecting the production progress, and the large friction will also scratch the inner wall of the spiral tube, affecting the production quality. Summary of the invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a full-motion roller spiral winding tube forming machine, which can reduce the friction between the spiral tube and the driving roller, reduce the axial resistance of the spiral tube during forming, and improve production efficiency.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical scheme: a full-motion roller spiral winding tube forming machine, including a driving roller and a surrounding sleeve, the surrounding sleeve is arranged outside the driving roller, and a plurality of rollers are evenly arranged on the driving roller along the circumferential direction, and the rollers can rotate along the axial direction of the driving roller.

[0006] When the spiral tube is being formed, the inner wall contacts the roller. When the spiral tube moves axially, it slides axially through the roller, reducing the friction force in the axial direction, so that the spiral tube can be formed more smoothly.

[0007] The beneficial effect of the above-mentioned full-motion roller spiral winding tube forming machine is that the friction force on the inner wall of the spiral tube in the axial direction is reduced by the roller, so that the material is discharged faster and the production efficiency is improved.

[0008] Furthermore, a plurality of grooves are formed on the driving roller along the circumferential direction, and the roller is arranged in the grooves.

[0009] It is arranged in the groove so that the outer side of the roller is closer to the driving roller, thereby making the inner wall of the spiral tube closer to the driving roller, and the support is more stable when the driving roller drives the roller to form.

[0010] Furthermore, the roller comprises an outer roller, a connecting shaft and a bearing, threaded through holes are provided at both ends of the connecting shaft, threaded holes are provided at both sides of the groove, and the connecting shaft is connected to the driving roller by bolts;

[0011] The bearing is arranged on the connecting shaft, and the outer roller sleeve is arranged on the bearing.

[0012] The connecting shaft is fixed in the groove of the driving roller by bolts, and the outer roller rotates relative to the connecting shaft through the bearing.

[0013] Furthermore, the generatrix of the roller is in an arc shape and is concentric with the inner circle of the spiral tube, and the generatrix of the roller is always in contact with the inner wall of the spiral tube.

[0014] The arc-shaped roller always sticks to the inner wall of the spiral tube when rotating, further reducing the friction, making the spiral tube move more smoothly along the axial direction, and avoiding scratching the inner wall of the spiral tube.

[0015] Furthermore, the plurality of rollers are arranged as a roller group along the circumferential direction, and the driving roller is evenly provided with a plurality of roller groups along the axial direction.

[0016] Multiple roller groups can further reduce the friction on the inner wall of the spiral tube and form it faster.

[0017] Furthermore, the rollers of adjacent roller groups are staggered, and the generatrixes of the rollers of adjacent roller groups can be combined to form a circle and coincide with the inner diameter of the spiral tube.

[0018] The generatrix of adjacent roller groups forms a full circle, so that the friction force on the inner wall of the spiral pipe when it contacts the roller is more uniform, and the resulting pipe quality is better.

[0019] Furthermore, the surrounding sleeve includes a plurality of auxiliary rollers, an end face shield and a main engine mounting flange, one end of the driving roller is connected to a power source, and the main engine mounting flange is arranged on a side of the driving roller close to the power source;

[0020] One side of the driving roller in the circumferential direction is a feed port, and the auxiliary rollers are evenly arranged around the driving roller in the circumferential direction except the feed port, and the setting direction is parallel to the driving roller. The two ends of the auxiliary rollers are rotatably connected to the end face shield and the main machine mounting flange respectively.

[0021] The driving roller is driven to rotate by the power source, driving the sheet fed from the feeding port to be wound, and the main machine mounting flange is used to install the entire device. When the pipe is formed, the sheet rotates circumferentially, and the auxiliary roller guides the sheet to wind circumferentially, which can reduce friction, make circumferential forming smoother, and avoid the wear of the sheet when using a hard guide shell.

[0022] Furthermore, the auxiliary roller comprises a driven roller and a driving roller, and one end of the driving roller close to the main engine mounting flange passes through the main engine mounting flange and is connected to a power source.

[0023] The driven roller is not powered, but the active roller is powered. When the driving roller drives the plate to wrap circumferentially, the active roller can provide auxiliary force. At the same time, the driven roller and the plate rotate together, which can also reduce friction.

[0024] Furthermore, there are four active rollers, which are evenly arranged along the circumferential direction.

[0025] The four evenly distributed active rollers make the plate force more even and the spiral tube formed is of better quality.

[0026] Furthermore, a plurality of connection brackets are provided on the end face shield along the circumferential direction, and the other end of the connection bracket is connected to the main engine mounting flange.

[0027] The end face shield is connected to the main machine mounting flange through a connecting bracket to avoid deviation in the position of the driven roller. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] See also Figures 1 to 6 The present invention provides a full-motion roller spiral winding tube forming machine, including a driving roller 100 and a surrounding sleeve 300, wherein the surrounding sleeve 300 is sleeved outside the driving roller 100, and a feeding port 310 is provided on the surrounding sleeve 300, the plate is tilted and fed from the feeding port 310 into between the driving roller 100 and the surrounding sleeve 300, and driven by the driving roller 100, the plate rotates circumferentially and moves axially, and is spirally wound into a spiral tube.

[0037] Specifically, a plurality of rollers 210 and grooves are evenly arranged on the driving roller 100 along the circumferential direction, the number of rollers 210 is the same as the number of grooves, and the rollers 210 are arranged in the grooves. Figure 2 As shown, the roller 210 can rotate along the axial direction of the driving roller 100, and the roller 210 includes an outer roller 213, a connecting shaft 211 and a bearing 214. The connecting shaft 211 is arranged in the groove, and threaded through holes 212 are arranged at both ends, and threaded holes are also arranged on both sides of the groove. The connecting shaft 211 is fixed in the groove by bolts. The bearing 214 is arranged on the connecting shaft 211, and the roller 210 is sleeved on the bearing 214 and can rotate relative to the connecting shaft 211.

[0038] When the spiral tube is formed, the plate is clamped between the roller 210 and the surrounding sleeve 300. The driving roller 100 drives the plate to rotate circumferentially and discharge the plate axially. When moving axially, the inner wall of the spiral tube slides on the roller 210, thereby reducing friction, making the spiral tube discharge smoother and increasing production efficiency.

[0039] Specifically, the generatrix of the roller 210 is arc-shaped and concentric with the inner circle of the spiral tube. When the roller 210 rotates, it can always be in close contact with the inner wall of the spiral tube, preventing the roller 210 from scratching the inner wall of the spiral tube and reducing the resistance to the inner wall of the spiral tube.

[0040] Specifically, Figure 3 and Figure 4 As shown, one circle of the roller 210 around the circumference constitutes a roller group 200. In the present embodiment, in order to further reduce the friction force, a plurality of roller groups 200 are evenly arranged along the axial direction on the driving roller 100. When the driving roller 100 drives the spiral tube to rotate and move along the axial direction, the plurality of roller groups 200 can further reduce the friction force and make the pipe discharge faster, and can also provide sufficient supporting force to drive the spiral tube to rotate.

[0041] In this embodiment, the rollers 210 of adjacent roller groups 200 are staggered, and the generatrix of the rollers 210 of adjacent roller groups 200 can enclose a complete circle and coincide with the inner diameter of the spiral tube. By staggering the roller groups 200, the stress of the pipeline can be evenly released during the axial movement.

[0042] Specifically, Figure 5 and Figure 6 As shown, the surrounding sleeve 300 includes a plurality of auxiliary rollers 350, an end face shield 330 and a main machine mounting flange 320. The main machine mounting flange 320 is arranged on the side of the driving roller 100 close to the power source for mounting the entire device, and the end face shield 330 is arranged on the outside of the other end of the driving roller 100. The auxiliary rollers 350 are evenly arranged around the circumference of the driving roller 100 except for the feeding port 310, and the setting direction of the auxiliary rollers 350 is parallel to the driving roller 100. The two ends of the auxiliary rollers 350 are respectively connected to the main machine mounting flange 320 and the end face shield 330.

[0043] When the driving roller 100 drives the sheet to wind, the other side of the sheet slides on the auxiliary roller 350. The auxiliary roller 350 not only plays a guiding role, but also drives the sheet to encounter less resistance when being bent into a tube. Compared with the traditional hard shell guiding method, the sheet is not easily damaged, thereby improving the quality of the spiral tube.

[0044] In this embodiment, if Figure 6As shown, the auxiliary roller 350 includes a driven roller 351 and an active roller 352. The driven roller 351 is not driven by power and rotates with the movement of the plate when the plate is wound. The end of the active roller 352 close to the main machine mounting flange 320 passes through the main machine mounting flange 320 and is connected to a power source. Specifically, there are four active rollers 352, which are evenly arranged along the circumference. The active roller 352 can help the driving roller 100 drive the plate to bend and be formed into a spiral tube, and the evenly arranged four active rollers 352 make the force on the plate more uniform.

[0045] Specifically, a plurality of connecting brackets 340 are provided circumferentially on the end shield 330, and the other end of the connecting bracket 340 is connected to the mainframe mounting flange 320. The end shield 330 is fixed by the connecting bracket 340 to prevent the auxiliary roller 350 from bearing too much weight and causing position deviation.

[0046] The working principle of the above-mentioned full-motion roller spiral winding tube forming machine is: start the driving roller 100 and the active roller 352, and feed the plate in an inclined position from the feeding port 310 of the surrounding sleeve 300. The distance between the roller 210 and the auxiliary roller 350 is the thickness of the plate. After the plate enters, the driving roller 100 drives the plate to rotate in the circumferential direction and move in the axial direction. The inner wall of the plate contacts the roller 210 and slides on the roller 210 when moving in the axial direction. The outer wall of the plate contacts the active roller 352 and the driven roller 351 and slides on the active roller 352 and the driven roller 351 when moving in the circumferential direction.

[0047] The use of the above-mentioned full-motion roller spiral winding tube forming machine can reduce the axial friction force of the spiral tube during forming, and make the spiral tube discharge smoother by means of rollers. At the same time, auxiliary rollers are arranged in the circumferential direction, which can guide the plate and reduce the friction of the plate in the circumferential direction. This not only improves production efficiency, but also improves product quality.
