[0030] In addition, in the description of the present application, the terms "first", "second" and the like are only used for distinguishing description, and cannot be understood as indicating or implying relative importance.

[0031] Reference Figures 1-8 For the first embodiment of the utility model, a rotating lifting appliance for plastic dipping is provided, which comprises a rack 1, a plastic dipping pool 2, a driving rod 3, a lifting track 4 and a lifting ring 5, the driving rod 3 can move vertically, horizontally and longitudinally relative to the rack 1, the lifting track 4 is arranged to slide up and down relative to the rack 1, the lifting ring 5 is arranged to rotate relative to the lifting track 4, the plastic dipping pool 2 is located below the lifting track 4, the driving rod 3 has a plurality of clamping portions 6, the lifting ring 5 has a toothed plate 7 coaxially arranged thereon, the clamping portion 6 is used for engaging with the toothed plate 7, and the driving rod 3 is used for driving the lifting ring 5 to rotate after moving.

[0032] In the embodiment, in the plastic dipping process, first, the lifting ring 5 hanging the workpiece is installed on the lifting track 4, when the lifting ring 5 carrying the workpiece slowly dips into the plastic dipping pool 2 under the action of the lifting track 4, the driving rod 3 first rises or falls by a certain distance, adjusts the position in the vertical direction, so that it approaches the height of the lifting ring 5. Then the driving rod 3 is accurately positioned in the horizontal transverse direction, so that the clamping portion 6 on the driving rod 3 engages with the toothed plate 7 on the lifting ring 5. Then the driving rod 3 moves forward and backward, due to the engagement relationship between the clamping portion 6 and the toothed plate 7, the toothed plate 7 starts to drive the lifting ring 5 to rotate under the pushing of the clamping portion 6, and the lifting ring 5 further drives the entire workpiece to rotate uniformly in the plastic dipping liquid. In the rotating process, each surface of the workpiece can fully contact with the plastic dipping liquid, so that the thickness of the plastic dipping layer is more uniform, thereby improving the plastic dipping quality and protection performance of the product, and reducing the rate of defective products due to uneven plastic dipping.

[0033] Further, it further comprises a vertical moving frame 8, a horizontal moving frame 9 and a longitudinal moving frame 10, the vertical moving frame 8 is arranged on the rack 1 and moves vertically, the horizontal moving frame 9 is arranged on the rack 1 and moves horizontally, the longitudinal moving frame 10 is arranged on the rack 1 and moves longitudinally, and the driving rod 3 is arranged on the longitudinal moving frame 10.

[0034] In this embodiment, when the lifting ring 5 carries the workpiece and slowly immerses into the dipping tank 2 under the action of the lifting rail 4 in the plastic dipping process, the vertical moving frame 8 is first started, and rises or falls by a certain distance to adjust the position of the driving rod 3 in the vertical direction, so that it approaches the height of the lifting ring 5. Then the horizontal moving frame 9 starts to work, and drives the driving rod 3 to accurately position in the horizontal transverse direction, so that the clamping part 6 on the driving rod 3 engages with the toothed plate 7 on the lifting ring 5. Subsequently, the longitudinal moving frame 10 pushes the driving rod 3 to move forward and backward, and due to the engagement relationship between the clamping part 6 and the toothed plate 7, the toothed plate 7 starts to drive the lifting ring 5 to rotate under the pushing of the clamping part 6.

[0035] Further, it further comprises a support 11, a roller 12, a connecting piece 13 and a hanger 14, the support 11 is movably arranged in the lifting rail 4, the roller 12 is rotatably arranged on the support 11, the connecting piece 13 is hingedly connected with the support 11 and the hanger 14 at two ends respectively, and the connecting piece 13 is at least two.

[0036] In this embodiment, when the lifting ring 5 is installed to the lifting rail 4, the roller 12 effectively reduces the friction force during movement due to its good rotating performance, so that the support 11 can smoothly travel on the lifting rail 4. When the support 11 reaches the specified position and stops moving, the hanger 14 will have a certain tendency to sway due to inertia. However, since the connecting piece 13 is hingedly connected with the support 11 and the hanger 14, this hinged structure allows the hanger 14 to slightly swing within a certain range relative to the support 11. Through the buffering of the hinged structure, the swaying energy is effectively dispersed, avoiding excessive impact on the whole hanger structure. Moreover, since at least two connecting pieces 13 are provided, the hanger 14 can be stably connected and supported from different positions.

[0037] Further, the connecting piece 13 comprises a vertical rod one 1301, a horizontal rod 1302 and a vertical rod two 1303, the top end of the vertical rod one 1301 is hingedly connected to the support 11, the bottom end is hingedly connected to the middle part of the horizontal rod 1302, the vertical rod two 1303 is two, the top ends of the two vertical rod two 1303 are hingedly connected to the two ends of the horizontal rod 1302 respectively, and the bottom ends of the two vertical rod two 1303 are hingedly connected to the hanger 14.

[0038] In this embodiment, when the support 11 reaches the designated position and stops moving, the whole lifting tool still has a tendency to continue moving forward due to the inertia. The top end of the vertical rod one 1301 of the connecting piece 13 is hinged to the support 11, the bottom end is connected to the middle part of the horizontal rod 1302, and the vertical rod two 1303 is connected to the horizontal rod 1302 and the lifting bracket 14. A parallelogram structure is formed among the horizontal rod 1302, the two vertical rod twos 1303 and the lifting bracket 14. In this way, the inertial force is effectively dispersed to the whole connecting piece 13, avoiding the structural damage or instability caused by the concentration of the inertial force in a certain part. The design of the swingable connecting piece 13 can effectively maintain the overall stability of the lifting tool.

[0039] Further, the connecting rod 15 is swingably arranged on the lifting bracket 14, and the lifting ring 5 is rotatably arranged on the connecting rod 15.

[0040] In this embodiment, at the moment when the clamping part 6 on the driving rod 3 contacts the toothed plate 7 on the lifting ring 5, the connecting rod 15 is swingably arranged on the lifting bracket 14. The connecting rod 15 will automatically swing slightly according to the slight impact force generated when the clamping part 6 approaches, which can effectively buffer the impact force generated at the moment when the clamping part 6 contacts the toothed plate 7.

[0041] With the buffering of the connecting rod 15, the clamping part 6 and the toothed plate 7 can smoothly mesh, and then the vertical moving frame 10 continues to move, driving the lifting ring 5 to rotate through the meshing relationship between the clamping part 6 and the toothed plate 7. The lifting ring 5 drives the workpiece to stably rotate in the plastic dipping liquid, so that the plastic dipping liquid uniformly wraps the surface of the workpiece.

[0042] Further, the swing lock piece 16 is hingedly arranged on the lifting track 4. The swing lock piece 16 has a first end and a second end. The first end has a lock part 17. The lifting track 4 has a lock hole 18. After the swing lock piece 16 swings, the lock part 17 enters or exits the lock hole 18, which is used to block the roller 12 in the lifting track 4.

[0043] Further, the cross beam 19 is arranged on the rack 1. After the lifting track 4 lifts, the cross beam 19 abuts or cancels the abutment of the second end of the swing lock piece 16, which is used to drive the swing lock piece 16 to swing.

[0044] In this embodiment, in the normal state, the cross beam 19 abuts the second end of the swing lock piece 16. At this time, the first end of the swing lock piece 16 is lifted, the lock part 17 is located above the lock hole 18 and does not enter the lock hole 18, and the roller 12 can freely roll in the lifting track 4.

[0045] When the lifting track 4 begins to descend for the plastic dipping operation, the crossbeam 19 gradually comes out of contact with the second end of the swing lock 16 as the lifting track 4 descends, and when the lifting track 4 descends to a certain distance, the crossbeam 19 no longer presses the second end of the swing lock 16. At this time, the swing lock 16 begins to swing around the middle hinge point under the gravity of the lock 17, and the lock 17 gradually enters the lock hole 18, thereby effectively blocking the rollers 12 in the lifting track 4, so that the hanging ring 5 is fixed at the current position during the lifting process, and the shaking during the lifting process is avoided.

[0046] After the plastic dipping is completed, the lifting track 4 begins to rise, and when it rises to a certain height, the crossbeam 19 again contacts and presses the second end of the swing lock 16, so that the first end of the swing lock 16 is lifted, the lock 17 is separated from the lock hole 18, and the rollers 12 can freely roll in the lifting track 4, facilitating the unloading.

[0047] The cooperation of the swing lock 16 and the crossbeam 19 realizes the automatic stabilization of the hanging ring 5 during the lifting process. When the lifting track 4 descends, no additional power or complex control device is needed, and the lock 17 is automatically inserted into the lock hole 18 by the gravity of the swing lock 16, so that the rollers 12 are blocked, and the hanging ring 5 is prevented from moving on the lifting track 4 due to accidental external force or shaking. The design structure is relatively simple, and only the swing lock 16, the crossbeam 19, and the lock hole 18 on the lifting track 4 are needed, without complex electronic control or hydraulic drive system, thereby reducing the failure rate and maintenance cost of the equipment.

[0048] Further, the clamping part 6 is a vertical cylinder.

[0049] In this embodiment, the connecting rod 15 slightly swings to eliminate the impact force at the moment when the clamping part 6 contacts the toothed plate 7. In this process, even if the position of the toothed plate 7 changes due to the swing of the connecting rod 15, since the clamping part 6 is a cylinder and has a relatively long length, the toothed plate 7 can still smoothly engage with the clamping part 6 after the swing, and the circumference of the clamping part 6 can well adapt to the deviation of the toothed plate 7, and still engage with the clamping part 6.

[0050] Further, the hanging ring 5 is V-shaped.

[0051] In this embodiment, when it is needed to install a hook on the hanging ring 5 to hang a workpiece, since the hanging ring 5 is V-shaped, the connecting part of the hook is placed in the groove of the hanging ring 5, and the hook can be kept in a relatively fixed position in the hanging ring 5 and is not easy to fall off or deviate.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
