Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle feeding, and more specifically to a screw feeder for PF corrugated pipe production. Background Art

[0002] A plastic corrugated pipe refers to a tubular elastic sensitive element formed by connecting foldable corrugated sheets made of plastic along the folding and telescoping direction. The corrugated pipe is widely used in instruments and meters. Its main purpose is to serve as a measuring element of a pressure measuring instrument, converting pressure into displacement or force. The corrugated pipe wall is relatively thin, with high sensitivity, and the measurement range is from dozens of pascals to dozens of megapascals.

[0003] In the existing production of plastic corrugated pipes, plastic is extruded by an extruder for plastic production. When feeding, a screw feeder is used to transport plastic particles into the extruder. The screw feeder mainly consists of a feed box and a screw conveyor rod driven by a motor. When feeding in the feed box, since the feed box is at a certain height from the ground, at this time, workers need to lift and turn over the loading box filled with raw materials, which is rather laborious and inconvenient. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a screw feeder for PF corrugated pipe production to solve the problems existing in the above-mentioned background art.

[0005] The utility model provides the following technical solution: A screw feeder for PF corrugated pipe production, including a feeder main body. Two mounting plates are fixedly connected to the side of the material frame of the feeder main body. An installation block is fixedly connected to the side of the mounting plate. A first installation shaft is fixedly connected to the opposite surfaces of the two installation blocks. A first annular seat is rotatably connected to the surface of the first installation shaft. An electric push rod is fixedly connected to the surface of the first annular seat. Rotating plates are rotatably connected to the opposite surfaces of the two mounting plates. A second installation shaft is fixedly connected to the opposite surfaces of the two rotating plates. A second annular seat is rotatably connected to the surface of the second installation shaft. The telescopic end of the electric push rod is fixedly connected to the surface of the second annular seat. A connecting strip is fixedly connected to the side of the rotating plate away from the mounting plate. A placing plate is fixedly connected to the lower surface of the connecting strip. A loading box is detachably installed on the upper surface of the placing plate. A moving wheel is fixedly connected to the lower surface of the loading box. A through hole for the moving wheel to pass through is opened on the upper surface of the placing plate. The setting of the moving wheel facilitates the pushing of the loading box after loading plastic particles, and the setting of the through hole can directly move the moving wheel into the through hole without lifting the loading box.

[0006] Further, a vertical plate is fixedly connected to the upper surface of the placement plate. The side surface of the bearing box is lapped with the side surface of the vertical plate. A connecting plate is fixedly connected to the side of the bearing box close to the vertical plate. A groove is formed in the side surface of the placement plate. The surface of the connecting plate is lapped with the inner wall of the groove. T-shaped grooves are formed in both the upper surface and the lower surface of the connecting plate. T-shaped inserts are slidably connected to the inner walls of the T-shaped grooves. A connecting spring is fixedly connected to the opposite surfaces of the T-shaped inserts and the T-shaped grooves. Both sides of the T-shaped insert are arc-shaped. Positioning grooves adapted to the T-shaped inserts are formed in both the inner top wall and the inner bottom wall of the groove. The surface of the T-shaped insert is lapped with the inner wall of the positioning groove. The settings of the T-shaped insert, the connecting spring, the connecting plate, and the vertical plate can fix the position of the bearing box on the placement plate and ensure stability.

[0007] Further, a box door is installed on the upper surface of the bearing box, and a handle is installed on the side surface of the bearing box. The number of the moving wheels is four, and the four moving wheels are arranged in a rectangular array on the lower surface of the bearing box. The lower surface of the bearing box is lapped with the upper surface of the placement plate.

[0008] The technical effects and advantages of the present utility model are as follows:

[0009] 1. For the screw feeding machine for PF corrugated pipe production, place the bearing box filled with plastic particle raw materials on the placement plate. The moving wheels move to the through holes of the placement plate. Start the electric push rod. The electric push rod drives the second installation shaft to rotate. At this time, the second installation shaft drives the rotating plate to rotate. The rotating plate drives the bearing box to rotate through the placement plate. At this time, the bearing box rotates above the hopper of the main body of the feeding machine, so that the feeding machine does not need to manually lift the bearing box, which is convenient for filling the feeding machine.

[0010] 2. For the screw feeding machine for PF corrugated pipe production, after placing the bearing box on the placement plate, push the bearing box so that the connecting plate is inserted into the groove of the placement plate. At this time, the arc surface of the T-shaped insert is forced to be received in the T-shaped groove, and the connecting spring is compressed. After the T-shaped insert moves to the position of the positioning groove, at this time, the T-shaped insert is inserted into the positioning groove under the elastic force of the connecting spring, so as to fix the position of the connecting plate and ensure the stability during the rotation of the bearing box. Pull the bearing box directly, and the arc surface of the T-shaped insert is also forced to be received, which is convenient for removing the bearing box. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] A vertical plate 13 is fixedly connected to the upper surface of the placing plate 10. The side of the receiving box 11 abuts against the side of the vertical plate 13. A connecting plate 14 is fixedly connected to the side of the receiving box 11 close to the vertical plate 13. A groove is opened on the side of the placing plate 10. The surface of the connecting plate 14 abuts against the inner wall of the groove. T-shaped grooves are opened on both the upper surface and the lower surface of the connecting plate 14. A T-shaped insert 15 is slidably connected to the inner wall of the T-shaped groove.

Positioning grooves adapted to the T-shaped insert 15 are opened on both the inner top wall and the inner bottom wall of the groove. The surface of the T-shaped insert 15 abuts against the inner wall of the positioning groove.

[0019] After placing the loading box 11 on the placing plate 10, push the loading box 11 to insert the connecting plate 14 into the groove of the placing plate 10. At this time, the arc surface of the T-shaped insert 15 is stressed and received in the T-shaped groove, and the connecting spring 16 is compressed. After the T-shaped insert 15 moves to the position of the positioning groove, at this time, the T-shaped insert 15 is inserted into the positioning groove under the elastic force of the connecting spring 16, thereby fixing the position of the connecting plate 14 and ensuring the stability during the rotation of the loading box 11.

[0021] Place the loading box 11 filled with plastic particle raw materials on the placing plate 10. The moving wheels 12 move into the through holes of the placing plate 10. Start the electric push rod 6. The electric push rod 6 pushes the second installation shaft 8 to rotate. At this time, the second installation shaft 8 drives the rotating plate 7 to rotate. The rotating plate 7 drives the loading box 11 to rotate through the placing plate 10. At this time, the loading box 11 rotates above the material box of the main body 1 of the feeding machine, so that the feeding machine does not need to manually lift the loading box 11, facilitating the filling of the feeding machine.

[0022] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
