[0028] When the above scheme is put into actual use, the steel pipe 2 to be used is sleeved on the outside of the internal threaded rod 9 and one end is placed close to the fixed plate 4, the bottom of the steel pipe 2 that has been cooled by thermoplastic molding is aligned with the conveyor belt 5 and placed above the bottom plate 1, the second motor 7 is started to drive the conveyor belt 5 to make the plastic pallet slide on the bottom plate 1, and when one end of the internal threaded rod 9 enters the interior of the plastic pallet, the alignment and cleaning component is started, and the alignment and cleaning component automatically cleans the burrs inside the plastic pallet, and controls the direction of the plastic pallet to align it with the steel pipe 2 and insert the steel pipe 2 into the plastic pallet. The advantage of this is that multiple steel pipes 2 can be installed into the interior of the pallet at the same time through the alignment and cleaning component, and the parts of the interior of the pallet that are inconvenient to clean can be deburred before installation, and the alignment is automatically performed during the process, so that the pallet can be aligned with the steel pipe 2 and installed, effectively improving the efficiency of the installation of the steel pipe 2 inside the pallet.

[0029] As a further solution of the present invention, the alignment cleaning assembly includes a connecting rod 6, which is rotatably sleeved on the outside of the internal threaded rod 9, one end of the connecting rod 6 is fixedly connected to the fixing plate 4, a first fixing ring 17 is fixedly connected to the connecting rod 6, a front end of the first fixing ring 17 is rotatably connected to a plurality of second rotating rods 14 distributed equidistantly, a front end of the second rotating rod 14 is rotatably connected to a first supporting plate 13, a front end of the first supporting plate 13 is rotatably connected to a first rotating rod 12, a front end of the first rotating rod 12 is rotatably connected to a first connecting ring 8, the first connecting ring 8 is spirally sleeved on the outside of the internal threaded rod 9, The first connecting ring 8 is rotatably connected to the connecting rod 6, a fixing sleeve 19 is fixedly connected to the connecting rod 6, a sliding sleeve 16 is slidably sleeved on the connecting rod 6, a reset spring 18 for resetting the sliding sleeve 16 is sleeved on the connecting rod 6, an alignment piece 10 is fixedly connected to the rear end of the first connecting ring 8, a slot 15 for docking with the alignment piece 10 is provided on the fixing sleeve 19, and the alignment piece 10 can pass through the slot 15 and contact the sliding sleeve 16, a plurality of first motors 3 are fixedly connected to the rear end of the fixing plate 4, and the output shafts of the first motors 3 respectively pass through the fixing plate 4 and are fixedly connected to the corresponding internal threaded rods 9;

[0030] When the above scheme is put into actual use, when the pallet slides along the conveyor belt 5 to the first support plate 13 and enters the reserved hole of the pallet, the first motor 3 is started to drive the internal threaded rod 9 to rotate, and the internal threaded rod 9 drives the first connecting ring 8 to slide backward, so that the first rotating rod 12 and the second rotating rod 14 are folded, and the first support plate 13 is extended outward until the first support plate 13 slides to a position in contact with the inner wall of the hole of the pallet. In this way, the pallet can be aligned through the contact between the first support plate 13 and the inner wall of the hole, so that the pallet maintains the position docking with the steel pipe 2. When the first support plate 13 docks with the inner wall of the pallet, the rotation of the first motor 3 is stopped. There are rollers on the first support plate 13 to reduce friction, so that after the first support plate 13 contacts the inner wall of the pallet, the first support plate 13 and the pallet can still slide relative to each other through the rollers.

[0031] As a further solution of the present invention, a second fixing ring 25 is fixedly connected to the connecting rod 6 at the rear side of the first fixing ring 17, a front end of the second fixing ring 25 is rotatably connected to a plurality of fourth rotating rods 24 that are equidistantly distributed, a front end of the fourth rotating rod 24 is rotatably connected to a second supporting plate 23, a front end of the second supporting plate 23 is rotatably connected to a third rotating rod 21, a front end of the third rotating rod 21 is rotatably connected to a second connecting ring 20, the second connecting ring 20 is spirally sleeved on the outside of the internal threaded rod 9, the second connecting ring 20 is rotatably connected to the connecting rod 6, and a blade 22 is fixedly connected to the second supporting plate 23;

After the first support plate 13 contacts the inner wall of the hole, the blade 22 on the second support plate 23 will contact the inner wall of the hole. As the tray slides, the blade 22 enters the inside of the hole of the tray and scrapes off the burrs on the hole, thereby achieving the effect of removing burrs from the inside of the tray.

[0033] As a further solution of the present invention, the rear end of the connecting rod 6 is fixedly connected to a third fixing ring 31, the front end of the third fixing ring 31 is rotatably connected to a plurality of sixth rotating rods 30 that are equidistantly distributed, the front end of the sixth rotating rod 30 is rotatably connected to a third supporting plate 28, the front end of the third supporting plate 28 is rotatably connected to a fifth rotating rod 27, the front end of the fifth rotating rod 27 is rotatably connected to a third connecting ring 26, the third connecting ring 26 is spirally sleeved on the outside of the internal threaded rod 9, the third connecting ring 26 is rotatably connected to the connecting rod 6, and a stopper 29 is fixedly connected to the third supporting plate 28;

[0034] When the above scheme is put into actual use, when installing the steel pipe 2, the steel pipe 2 is slid to the position where the rear end contacts the front end of the stopper 29, and the internal threaded rod 9 rotates to drive the third connecting ring 26 to slide backward, and the third connecting ring 26 drives the fifth rotating rod 27 and the sixth rotating rod 30 to flip so that the third support plate 28 extends outward, and the steel pipe 2 is aligned through the third support plate 28 so that it is consistent with the position direction of the hole inside the pallet. When the pallet slides along the conveyor belt 5 to the position where it docks with the steel pipe 2, due to the restriction of the stopper 29 on the steel pipe 2, the steel pipe 2 will gradually enter the interior of the pallet, and the pallet will stop after sliding to the position where one end contacts the stopper 29. At this time, the docking of the steel pipe 2 and the pallet is completed, and the conveyor belt 5 can be rotated in the opposite direction to remove the pallet after the steel pipe 2 is installed from the bottom plate 1, and a new pallet and steel pipe 2 can be replaced and continued processing.

[0035] As a further solution of the present invention, the stopper 29 is sleeved with an anti-skid pad with a large friction coefficient;

[0036] When the above solution is put into actual use, the anti-skid pad plays a buffering role on the tray, so that the impact force when one end of the tray contacts the stopper 29 is partially weakened.

[0037] A production process for a plastic pallet, the process comprising the following steps:

[0038] Step 1: Sleeve the steel pipe 2 to be used on the outside of the internal threaded rod 9 and place one end close to the fixed plate 4;

[0039] Step 2: Align the bottom of the integrally thermoplastic-formed and cooled steel pipe 2 with the conveyor belt 5 and place it on the bottom plate 1;

[0040] Step 3: Start the conveyor belt 5 to drive the plastic pallet to slide on the bottom plate 1, and start the alignment cleaning component when one end of the internal threaded rod 9 enters the interior of the plastic pallet;

[0041] Step 4: The alignment cleaning component automatically cleans the burrs inside the plastic pallet, controls the direction of the plastic pallet so that it is aligned with the steel pipe 2, and inserts the steel pipe 2 into the plastic pallet.

[0042] Working principle: The steel pipe 2 to be used is sleeved on the outside of the internal threaded rod 9. When installing the steel pipe 2, the steel pipe 2 is slid to the position where the rear end contacts the front end of the stopper 29. The bottom of the steel pipe 2 after the integral thermoplastic molding and cooling is aligned with the conveyor belt 5 and placed above the bottom plate 1. The second motor 7 is started to drive the conveyor belt 5 to make the plastic pallet slide on the bottom plate 1.

[0043] When the pallet slides along the conveyor belt 5 to the first support plate 13 and enters the reserved hole of the pallet, the first motor 3 is started to drive the internal threaded rod 9 to rotate, and the internal threaded rod 9 drives the first connecting ring 8 to slide backward, so that the first rotating rod 12 and the second rotating rod 14 are folded, and the first supporting plate 13 is extended outward until the first supporting plate 13 slides to a position in contact with the inner wall of the hole of the pallet. In this way, the first supporting plate 13 is in contact with the inner wall of the hole, and the pallet can be aligned so that the pallet remains in the position of docking with the steel pipe 2. The rotation of the internal threaded rod 9 also drives the second connecting ring 20 to slide backward, and the second connecting ring 20 drives the third rotating rod 21 and the fourth rotating rod 24 to rotate, so that the second supporting plate 23 is extended outward like the first supporting plate 13, but the length of the third rotating rod 21 is not as long as the first rotating rod 12. After the first supporting plate 13 contacts the inner wall of the hole, the second The blade 22 on the support plate 23 will contact the inner wall of the hole. As the pallet slides, the blade 22 enters the inside of the pallet hole and scrapes off the burrs on the hole. The internal threaded rod 9 rotates to drive the third connecting ring 26 to slide backward. The third connecting ring 26 drives the fifth rotating rod 27 and the sixth rotating rod 30 to flip so that the third support plate 28 extends outward. The steel pipe 2 is positioned correctly through the third support plate 28 so that it is consistent with the position and direction of the hole inside the pallet. When the pallet slides along the conveyor belt 5 to the position where it docks with the steel pipe 2, due to the restriction of the stopper 29 on the steel pipe 2, the steel pipe 2 will gradually enter the inside of the pallet, and the pallet will stop after sliding to the position where one end contacts the stopper 29. At this time, the docking of the steel pipe 2 and the pallet is completed. The conveyor belt 5 can be rotated in the opposite direction to remove the pallet with the steel pipe 2 installed from the bottom plate 1, and a new pallet and steel pipe 2 can be replaced and the processing can continue.
