The embodiments of this utility model will be described below based on its overall structure.
[0028] Reference Figures 1 to 5 In this embodiment of the present invention, a rough edge treatment device for plastic pallet production includes:
[0029] Operating console 1, with a conveyor belt 4 installed inside the operating console 1;
[0030] Pallet alignment mechanism 2 is installed above the operating table 1 and is used to clamp and align plastic pallets.
[0031] The pallet locking and rotating mechanism 3 is installed above the operating table 1 and is used to rotate the plastic pallet around its center.
[0032] The burr-removing mechanism 6 is used to adjust its position to remove burrs from the plastic tray.
[0033] The tray locking rotation mechanism 3 includes a second motor 31. The rotation shaft of the second motor 31 is fixedly connected to an upper rotating plate 32. Two sets of upper fixing blocks 33 are symmetrically fixedly connected above the upper rotating plate 32. Two sets of first electric telescopic rods 34 are fixedly connected to the sides of the two sets of upper fixing blocks 33 that are close to each other. The movable end of the first electric telescopic rod 34 is fixedly connected to an arc-shaped clamping plate 35. Several sets of concave wheels 36 are rotatably connected to the inner side of the arc-shaped clamping plate 35. A third motor 37 is fixedly connected above one set of arc-shaped clamping plates 35.
[0034] Using the above scheme: after the first electric telescopic rod 34 drives the arc-shaped clamping plate 35 to clamp the pallet, the third motor 37 drives the concave wheel 36 to rotate to form a rotating pair. When in contact with the pallet, the pallet is driven to rotate by friction transmission. The second motor 31 can drive the entire clamping assembly and the pallet to rotate through the upper rotating plate 32.
[0035] The pallet alignment mechanism 2 includes a first motor 21, the rotation shaft of the first motor 21 is fixedly connected to the lower turntable 22, and one end of two sets of long connecting arms 23 is rotatably connected below the lower turntable 22. The other end of the two sets of long connecting arms 23 is rotatably connected to a set of connecting rods 24. A side moving plate 25 is fixedly connected above the connecting rods 24, and multiple sets of clamping and pressing rollers 26 are rotatably connected to the inner side of the side moving plate 25.
[0036] Using the above scheme: when the first motor 21 drives the lower turntable 22 to rotate, the long connecting arm 23 cooperates with the connecting rod 24 to drive the symmetrically arranged side moving plates 25 to move synchronously towards each other. During this process, the clamping and pressing roller 26 applies radial clamping force to achieve centering when it contacts the tray, and reduces the displacement resistance through rolling friction.
[0037] The rough edge polishing mechanism 6 includes a second upper fixed plate 61, and two sets of third electric telescopic rods 62 are fixedly connected to the side of the second upper fixed plate 61. An electric polisher 63 is fixedly connected to the movable end of the third electric telescopic rod 62.
[0038] Using the above scheme: the third electric telescopic rod 62 compensates for the position of the electric grinder 63 according to the position of the tray, and drives the electric grinder 63 to grind the plastic tray when it is close to the rough edge position.
[0039] The operating table 1 includes a main table surface 11, two sets of symmetrical connecting rod through slots 12 are provided above the main table surface 11, and a discharge ramp 13 is provided above the main table surface 11.
[0040] Using the above scheme: the connecting rod through groove 12 and the connecting rod 24 form a dynamic seal to ensure the stability of the mechanism's movement. When the finished pallet is pushed to the discharge ramp 13 by the finished product unloading mechanism 5, it automatically slides down and discharges due to the tangential action of the gravity component.
[0041] It also includes a finished product unloading mechanism 5, which includes a first upper fixed plate 51, a second electric telescopic rod 52 embedded in the inner side of the first upper fixed plate 51, and an arc-shaped push plate 53 fixedly connected to the movable end of the second electric telescopic rod 52.
[0042] Using the above scheme: After the rough edges of the plastic pallet are polished, the second motor 31 drives the upper rotating plate 32 to rotate to a suitable angle, and the second electric telescopic rod 52 drives the arc-shaped push plate 53 to apply force along the tangent direction of the pallet. By utilizing the guiding characteristics of the arc surface, the pallet is accurately pushed to the discharge ramp 13.
[0043] The second motor 31 is embedded inside the main table 11. The rotating shaft of the second motor 31 passes through the upper part of the main table 11 and is fixedly connected to the lower turntable 22. The rotating shaft of the third motor 37 passes through the arc-shaped clamping plate 35 and is fixedly connected to one of the concave wheels 36. The first motor 21 is embedded inside the main table 11. The rotating shaft of the first motor 21 passes through the lower part of the main table 11 and is fixedly connected to the lower turntable 22. The connecting rod 24 passes through the connecting rod slot 12 and is fixedly connected to the side moving plate 25 above the main table 11. The concave wheels 36 and the clamping and pressing rollers 26 are both made of metal on the inside and covered with soft rubber on the outside. When the clamping and pressing rollers 26 squeeze the plastic tray, they can provide downward pressure so that the bottom of the plastic tray can be tightly attached to the conveyor belt 4. The first upper fixing plate 51 and the second upper fixing plate 61 are fixedly connected above the main table 11.
[0044] The working principle of this utility model is as follows: the plastic pallet is transported to the processing area of the main table 11 via the conveyor belt 4 inside the operating table 1. At this time, the clamping and pressing roller 26 is in the open state, and the side moving plate 25 is located at the extreme positions on both sides of the main table 11.
[0045] The first motor 21 drives the lower turntable 22 to rotate clockwise. Through the linkage between the long connecting arm 23 and the connecting rod 24, it drives the two sets of side moving plates 25 to move towards each other along the connecting rod through groove 12. When the clamping and pressing roller 26 contacts the edge of the pallet, it applies radial clamping force under the elastic deformation of the soft rubber layer. At the same time, the metal core makes the bottom of the pallet stick tightly to the conveyor belt 4 through the downward pressure. At this time, the conveyor belt 4 can drive the plastic pallet to move closer to the two sets of arc-shaped clamping plates 35.
[0046] The second motor 31 drives the upper rotating plate 32 to rotate to the clamping position. The first electric telescopic rod 34 pushes the two sets of arc-shaped clamping plates 35 to close, clamping the plastic pallet. The soft rubber layer of the concave wheel 36 forms frictional contact with the outer periphery of the pallet. The third motor 37 drives the pallet to rotate around its own axis through the active concave wheel 36. At this time, the third electric telescopic rod 62 drives the electric grinder 63 to move to the appropriate position, and the electric grinder 63 contacts and grinds the burr parts of the pallet, completing the circumferential grinding in conjunction with the pallet's rotation.
[0047] After grinding, the second motor 31 drives the entire clamping assembly to rotate via the upper rotating plate 32, rotating it to the discharge position. The second electric telescopic rod 52 pushes the arc-shaped push plate 53 to apply force along the tangent of the pallet. The guide arc surface of the arc-shaped push plate 53 guides the pallet to slide smoothly into the discharge ramp 13, and the pallet is automatically discharged by utilizing the component of gravity.
[0048] After the unloading of a single pallet is completed, each mechanism's actuator returns to its initial position, awaiting the next work cycle. The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
