Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe processing technology, specifically to a port processing device for PP corrugated pipe production. Background Technology

[0002] Polypropylene (PP) corrugated pipes, as a type of high-performance plastic pipe, are widely used in municipal drainage and sewage systems, communication cable protection conduits, agricultural irrigation, and industrial fluid transportation due to their excellent chemical corrosion resistance, good flexibility, lightweight and high strength, and cost advantages. Their unique corrugated structure design not only enhances the ring stiffness and compressive strength of the material, but also effectively compensates for deformation caused by thermal expansion and contraction, ensuring long-term stability. However, during the extrusion molding process, due to factors such as the mold parting surface gap, the shear effect of molten material flow, and shrinkage deformation during cooling and shaping, burrs, flash, and other defects will inevitably form at both ends of the pipe.

[0003] For example, patent announcement number CN 218487990 U discloses a burr removal structure for plastic corrugated pipes, relating to the field of corrugated pipe processing technology. This utility model includes a mounting frame and a grinding assembly; the grinding assembly is rotatably fitted with the mounting frame; the mounting frame includes a support plate; a baffle is fixedly connected between the two support plates; a clamping component is slidably fitted with the sliding channel; a sliding clamping plate is slidably fitted with the sliding channel; compression springs are symmetrically fixedly connected between the sides of the fixed plate and the sliding clamping plate and the sliding channel; both the baffle and the sliding clamping plate have insertion holes. This utility model inserts both ends of the corrugated pipe into the insertion holes on the fixed plate and the sliding clamping plate respectively. Under the force of the corresponding compression springs, the sliding clamping plate presses the plastic corrugated pipe tightly against the baffle. Under the force of the corresponding compression springs, the fixed plate moves, causing one end of the corrugated pipe to be inserted between the inner and outer cylinders. Rotating the screw drives the arc-shaped clamping plate to press the end of the corrugated pipe tightly against the inner cylinder, achieving stable clamping and fixing of the corrugated pipe.

[0004] Based on the search of patent numbers and the shortcomings of existing technologies, the following was found:

[0005] Although this plastic corrugated pipe deburring structure can stably clamp the corrugated pipe, during use, the user needs to adjust the sliding clamp, the arc clamp, and the grinding plate in sequence during the positioning and grinding process. The average processing time for a single pipe is relatively long. Furthermore, when using the baffle and sliding clamp to position the corrugated pipe, the lack of a support structure makes it easy for the middle of the corrugated pipe to sag, causing the two ends of the corrugated pipe to shift towards the center. This makes it difficult to keep the end face of the corrugated pipe level, affecting the stability and flatness of subsequent grinding work. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 4 As shown, the present invention provides a port processing device for PP corrugated pipe production, including a support mechanism 1, the support mechanism 1 including a support frame 101, a support plate 102 fixedly connected to the top of the support frame 101, a positioning cylinder 103 fixedly connected to the top of the support plate 102, and a positioning mechanism 2 provided on the top of the support frame 101.

[0027] The positioning mechanism 2 includes an adjusting plate 201 that is movably connected to the top right side of the support frame 101. A movable plate 202 is slidably connected to the right side of the adjusting plate 201 via a slide rail. A first triangular plate 203 is fixedly connected to the bottom of the movable plate 202. A through hole 204 is provided at the bottom left side of the adjusting plate 201. An oblique column 205 is movably connected to the inner wall of the through hole 204. A support ring 206 is fixedly connected to the left side of the oblique column 205. The first triangular plate 203 is located at the top of the oblique column 205. A linkage mechanism 3 is provided at the top of the support frame 101.

[0028] The diameters of the angled post 205 and the support ring 206 are the same as the inner diameter of the through hole 204, which makes it easy for the angled post 205 to drive the support ring 206 to move left and right. At the same time, the support ring 206 is hollow, which reduces the overall weight and prevents the support ring 206 from tilting when it moves out of the through hole.

[0029] Thus, the linkage mechanism 3 includes a through groove 31, with a first sliding plate 32 slidably connected to the inner wall of the through groove 31. The top of the first sliding plate 32 is fixedly connected to the bottom of the adjusting plate 201. The top of the movable plate 202 is fixedly connected to a second triangular plate 33. The top of the adjusting plate 201 is slidably connected to a top plate 34 via a slide rail. The top of the support plate 102 is fixedly connected to a fixed plate 35 at the same horizontal position as the top plate 34. When the adjusting plate 201 drives the first sliding plate 32 to slide stably inside the through groove 31, it can simultaneously drive the top plate 34 to move closer to the fixed plate 35. When the top plate 34 contacts the fixed plate 35, and the adjusting plate 201 continues to move to the left, it can cause the top plate 34 to move along the surface of the second triangular plate 33, and at the same time, it can exert a downward pressure effect on it, thereby driving the movable plate 202 and the first triangular plate 203 to move downward and exert a pushing effect on the angled column 205.

[0030] The right side of the movable plate 202 is fixedly connected to a limiting frame 16. The limiting frame 16 is L-shaped and can prevent the top plate 34 from detaching from the second triangular plate 33, so that it is always at the top of the second triangular plate 33.

[0031] In addition, an installation groove 6 is provided on the left side of the adjustment plate 201. A first motor 7 is fixedly installed on the inner wall of the installation groove 6. A transmission rod 8 is fixedly connected to the output end of the first motor 7. A transmission gear 9 is fixedly installed on the surface of the transmission rod 8. A driven gear 10 is fixedly installed on the surface of the ring frame 4. The transmission gear 9 meshes with the driven gear 10.

[0032] An annular frame 4 is rotatably mounted inside the adjusting plate 201, and a grinding ring 5 is fixedly connected to the left side of the annular frame 4.

[0033] Furthermore, a second motor 11 is fixedly installed on the left side of the support frame 101. A lead screw 12 is fixedly connected to the output end of the second motor 11. The other end of the lead screw 12 passes through the first slide plate 32 and is rotatably connected to the right side of the inner wall of the support frame 101 through a bearing. The lead screw 12 is threadedly connected to the first slide plate 32.

[0034] The lead screw 12 is configured as a bidirectional lead screw, and a bearing seat 17 is movably installed in the middle of the surface of the lead screw 12. The bottom of the bearing seat 17 is fixedly connected to the bottom of the inner wall of the support frame 101.

[0035] The left side of the lead screw 12 is threaded with a second slide plate 13. The bottom of the second slide plate 13 is movably connected to the bottom of the inner wall of the support frame 101. The top of the second slide plate 13 is fixedly connected with a vertical plate 14. The right side of the vertical plate 14 is fixedly connected with a stabilizing plug 15 that engages with the inner wall of the positioning cylinder 103.

[0036] The bearing seat 17 can support the lead screw 12. The lead screw 12 can simultaneously drive the vertical plate 14 and the adjusting plate 201 to move towards the positioning cylinder 103. When the stabilizing plug 15 on the right side of the vertical plate 14 enters the positioning cylinder 103, the grinding ring 5 is in complete contact with the end face of the bellows. At this time, the second motor 11 is turned off, which allows the grinding ring 5 to continue grinding the end face of the bellows.

[0037] The working principle and usage process of this utility model are as follows: When in use, first push the corrugated pipe into the positioning cylinder 103 through the left side of the positioning cylinder 103, so that the end of the corrugated pipe that needs to be polished moves to the right side of the positioning cylinder 103. Then start the first motor 7, so that the output end of the first motor 7 drives the transmission rod 8 and the transmission gear 9 to rotate. The rotation of the transmission gear 9 can drive the ring frame 4 and the polishing ring 5 to rotate. Then start the second motor 11, so that the output end of the second motor 11 drives the lead screw 12 to rotate. The rotation of the lead screw 12 can simultaneously drive the first slide plate 32 and the second slide plate 13 to move closer to the positioning cylinder 103.

[0038] The first sliding plate 32 then drives the adjusting plate 201 to move to the left. When the top plate 34 of the adjusting plate 201 contacts the fixed plate 35 and continues to move to the left, the top plate 34 stops moving. Since the adjusting plate 201 continues to move to the left, the top plate 34 can continuously push the second triangle plate 33 and move along the surface of the second triangle plate 33, so that the second triangle plate 33 drives the movable plate 202 and the first triangle plate 203 to move downward in sequence. When the first triangle plate 203 contacts the beveled column 205 and continues to move downward, the first triangle plate 203 can push the beveled column 205 and the support ring 206 to move to the left inside the through hole 204, so that the support ring 206 gradually enters the interior of the bellows in the positioning cylinder 103, thereby providing a support effect for the inner wall of the bellows. When the grinding ring 5 contacts the end face of the bellows and continues to move to the left, it can provide a grinding effect for the end face.

[0039] At the same time, the rotation of the lead screw 12 can drive the second slide plate 13, the upright plate 14 and the stabilizing plug 15 to move to the right, so that the stabilizing plug 15 enters the interior of the positioning cylinder 103 and limits the left end of the bellows, further improving the stability of the bellows grinding. At this time, the lead screw 12 stops rotating, and the grinding ring 5 can continuously grind the bellows port.
