Description

TECHNICAL FIELD

[0001] The utility model relates to a dip plastic equipment technical field, specifically, relates to a kind of lifting appliance structure for double track dip plastic. BACKGROUND

[0002] In industrial production, dip plastic process is widely used in the surface treatment of various metal products to give the product good protective, decorative and other special properties. The traditional dip plastic production line mostly adopts single track design, and its operating principle mainly depends on chain transmission system. Under this structure, the chain as a power transmission medium drives the lifting appliance installed thereon to operate stably. The lifting appliance undertakes the task of hanging workpieces and ensures that the workpieces can move along the predetermined track in the production process.

[0003] Most dip plastic production lines need to stop the lifting appliance above the dip tank, drive the dip tank to rise, so that the workpiece is immersed in the dip tank. However, due to the need to accommodate a sufficient amount of dip plastic liquid to meet the dip plastic needs of the workpiece, the dip tank is often large in size and heavy in weight. In the selection and design of the lifting mechanism, the power device and transmission structure capable of bearing the huge weight of the dip tank need to be considered, which not only increases the manufacturing cost of the equipment, but also makes the structure of the entire production line complex.

[0004] If the dip tank does not rise, but the lifting appliance descends, the lifting appliance needs to be disconnected from the chain first to descend, and the lifting appliance needs to be connected with the chain again when it is reset upward, so a detachable connection method needs to be designed. The traditional detachable connection method is complex, such as using a telescopic part to drive a clamping jaw to clamp or release the lifting appliance by opening or closing the clamping jaw. This method also needs to add a telescopic assembly to the chain, which increases the load and structural complexity of the chain.

[0005] In view of the problems existing in the prior art, the prior art has not been well solved, which has brought trouble to the normal work in the field, therefore, there is an urgent need for a lifting appliance structure for double track dip plastic to solve the above problems.

After the lifting track is lifted, the locking column enters or leaves the locking slot.

[0009] The conveying track is provided with a gap. After the lifting track is lifted, the lifting track enters the gap and is connected with the conveying track, or leaves the gap and drives the lifting device to approach the plastic dipping pool.

The bottom ends of the two vertical rods two are hingedly connected with the lifting frame.

[0012] Optionally, the device further comprises a rack, a three-dimensional moving mechanism and a driving rod. The three-dimensional moving mechanism is arranged on the rack. The driving rod can move vertically, horizontally and longitudinally by means of the three-dimensional moving mechanism. The lifting track is arranged to slide on the rack,

[0013] The driving rod is provided with a plurality of clamping portions. The lifting ring is arranged to rotate relative to the lifting frame. The lifting ring is coaxially provided with a toothed plate. The clamping portions are used to engage with the toothed plate. The driving rod is used to drive the lifting ring to rotate after moving.

[0014] Optionally, the three-dimensional moving mechanism comprises a vertical moving frame, a horizontal moving frame and a longitudinal moving frame. The vertical moving frame is arranged to move vertically on the rack. The horizontal moving frame is arranged to move horizontally on the rack. The longitudinal moving frame is arranged to move longitudinally on the rack. The driving rod is arranged on the longitudinal moving frame.

[0015] Optionally, the device further comprises a connecting rod. The connecting rod is arranged to swing on the lifting frame. The lifting ring is arranged to rotate on the connecting rod.

[0016] Optionally, the clamping portion is a cylinder arranged vertically.

[0017] Optionally, the locking slot has a V-shaped opening and the direction is downward.

[0018] Optionally, the lifting ring is V-shaped.

[0019] The working principle and beneficial effects of this utility model are as follows:

[0020] During normal operation of the dual-track dip coating production line, the drive chain circulates within the drive track, driving the connected lifting device forward stably on the conveyor track. At this time, the locking pin on the lifting device is positioned within the locking groove of the drive chain locking plate, with the two working closely together to ensure effective power transmission.

[0021] Under normal conditions, the lifting rail and the conveying rail are connected to form a complete rail structure. When the lifting device moves to the lifting rail and the lifting rail begins to descend for the dip coating operation, as the lifting rail moves downward, the locking pins on the lifting device gradually disengage from the locking grooves of the drive chain locking plate. After the locking pins are completely disengaged from the locking grooves, the lifting device can independently descend into the dip coating tank with the lifting rail without being restricted by the drive chain. In the dip coating tank, the workpiece can undergo dip coating treatment smoothly.

[0022] After the dip coating is completed, the lifting track begins to rise and reset. Once the lifting track and the conveyor track are reassembled into a complete track structure, the locking pin accurately re-enters the locking groove. At this point, the drive chain can again drive the lifting device to continue moving along the conveyor track, transporting the dip-coated workpiece to subsequent curing, inspection, and other processes. The entire process is tightly and smoothly connected, ensuring the efficient and continuous operation of the production line.

[0023] This locking pin and locking groove mechanism ensures the effective separation and reconnection of the lifting device from the drive chain during the lifting process on the hoisting rail. Because the connection method of the locking pin and locking groove is simple and reliable, it does not place excessive load on the drive chain, and also reduces the high failure rate caused by complex connection structures.

[0038] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0039] Referring to Figures 1-9 For the first embodiment of the utility model, a kind of lifting appliance structure for double-track plastic dipping is provided, including drive track 1, conveying track 2, lifting track 3, plastic dipping pool 4, lifting appliance 5, drive chain 6, lock plate 7 and lock column 8, the drive track 1 and the conveying track 2 are arranged side by side, the lifting track 3 is set to lift and slide relative to the conveying track 2, the plastic dipping pool 4 is set below the lifting track 3,

[0040] The lifting appliance 5 is set to move relative to the length direction of the conveying track 2, for hoisting workpiece, the drive chain 6 is set to move in the drive track 1, the lock plate 7 is set on the drive chain 6, the lock plate 7 has lock groove 9, the lock column 8 is used to set on the lifting appliance 5, after the lifting track 3 lifts, the lock column 8 enters or separates from the lock groove 9,

[0041] The conveying track 2 has a gap, after the lifting track 3 lifts, enters the gap and is spliced with the conveying track 2, or separates from the gap and drives the lifting appliance 5 to be close to the plastic dipping pool 4.

[0042] In the embodiment, in the normal operation process of double-track plastic dipping production line, drive chain 6 circulates and moves in drive track 1, drives lifting appliance 5 connected therewith to stably move forward on conveying track 2.At this time, lock column 8 on lifting appliance 5 is in lock groove 9 of drive chain 6 lock plate 7, and the two are closely matched to ensure effective transmission of power.

[0043] Under normal conditions, lifting track 3 and conveying track 2 are spliced into complete track structure.When lifting appliance 5 moves to lifting track 3, and lifting track 3 starts to descend for plastic dipping operation, as lifting track 3 moves downward, lock column 8 on lifting appliance 5 gradually separates from lock groove 9 of drive chain 6 lock plate 7.After lock column 8 completely separates from lock groove 9, lifting appliance 5 can independently descend with lifting track 3 into plastic dipping pool 4, and will not be restricted by drive chain 6.In plastic dipping pool 4, workpiece can be smoothly subjected to plastic dipping treatment.

[0044] After plastic dipping is completed, lifting track 3 starts to rise and reset.When lifting track 3 and conveying track 2 are spliced into complete track structure again, lock column 8 accurately reenters lock groove 9, and at this time, drive chain 6 can drive lifting appliance 5 to continue moving along conveying track 2 again, conveying workpiece after plastic dipping to subsequent solidification, inspection and other process links, the whole process is closely connected and smooth, to ensure efficient continuous operation of production line.

[0045] The cooperation mechanism of the locking column 8 and the locking groove 9 ensures the effective separation and reconnection of the lifting tool 5 and the driving chain 6 during the lifting of the lifting tool 5 on the lifting rail 3. Since the connection mode of the locking column 8 and the locking groove 9 is simple and reliable, it does not add too much load to the driving chain 6, and reduces the problem of high failure rate caused by complex connection structure.

[0046] Further, the lifting tool 5 comprises a support 501, a roller 502, a connecting piece 503, a hanger 504 and a lifting ring 505, the support 501 is movably arranged in the conveying rail 2, the roller 502 is rotatably arranged on the support 501, the connecting piece 503 is hingedly connected with the support 501 and the hanger 504 at two ends respectively, the connecting piece 503 is at least two, and the lifting ring 505 is arranged on the hanger 504.

[0047] In the embodiment, the roller 502 effectively reduces the friction when the lifting tool 5 moves, thanks to its good rotation performance, so that the lifting tool 5 can smoothly travel on the conveying rail 2 at a set speed. When the lifting tool 5 reaches the position of the lifting rail 3 and stops moving, the connection between the chain and the lifting tool 5 is released at this time, and the lifting tool 5 will have a certain tendency to sway due to inertia. However, since the connecting piece 503 is hingedly connected with the support 501 and the hanger 504, the hanger 504 can slightly swing within a certain range relative to the support 501, and the swaying energy is effectively dispersed through the buffering of the hinged structure, avoiding excessive impact on the entire lifting tool 5 structure. Moreover, since at least two connecting pieces 503 are provided, the hanger 504 can be stably connected and supported from different positions.

[0048] Further, the connecting piece 503 comprises a vertical rod one 5031, a horizontal rod 5032 and a vertical rod two 5033, the vertical rod one 5031 is hingedly connected at the top end to the support 501 and at the bottom end to the middle of the horizontal rod 5032, the locking column 8 is arranged on the vertical rod one 5031, and the vertical rod two 5033 is two, the top ends of the two vertical rod two 5033 are hingedly connected to the two ends of the horizontal rod 5032, and the bottom ends of the two vertical rod two 5033 are hingedly connected to the hanger 504.

[0049] In the embodiment, when the lifting tool 5 transitions from the conveying rail 2 to the lifting rail 3, the lifting tool 5 reaches the lifting rail 3 and stops moving, at this time the roller 502 stops rolling in the lifting rail 3, and the lifting tool 5 as a whole still has a tendency to continue moving forward due to inertia.

[0050] The top end of the vertical rod 5031 of the connecting piece 503 is hinged to the support 501, the bottom end is connected to the middle part of the horizontal rod 5032, and the lock column 8 is arranged on the vertical rod 5031, and the vertical rod 5033 connects the horizontal rod 5032 and the hanging bracket 504, and a parallelogram structure is formed among the horizontal rod 5032, the two vertical rods 5033 and the hanging bracket 504. In this way, the inertial force is effectively dispersed to the whole connecting piece 503, avoiding the structural damage or instability caused by the concentration of the inertial force in a certain position, and the design of the dispersed swing connecting piece 503 can effectively maintain the overall stability of the lifting tool 5.

[0051] Further, the rack 10, a three-dimensional moving mechanism arranged on the rack 10 and a driving rod 11 capable of moving vertically, horizontally and longitudinally by means of the three-dimensional moving mechanism are further included, and the lifting track 3 is arranged on the rack 10 and slides up and down,

[0052] The driving rod 11 has a plurality of clamping portions 12, the lifting ring 505 is arranged rotatably relative to the hanging bracket 504, a toothed plate 13 is coaxially arranged on the lifting ring 505, the clamping portions 12 are used for engaging with the toothed plate 13, and the driving rod 11 is used for driving the lifting ring 505 to rotate after moving.

[0053] Further, the three-dimensional moving mechanism includes a vertical moving frame 14, a horizontal moving frame 15 and a longitudinal moving frame 16, the vertical moving frame 14 is arranged on the rack 10 and moves vertically, the horizontal moving frame 15 is arranged on the rack 10 and moves horizontally, the longitudinal moving frame 16 is arranged on the rack 10 and moves longitudinally, and the driving rod 11 is arranged on the longitudinal moving frame 16.

[0054] In the embodiment, in the dipping process of the double-track dipping production line, when the lifting tool 5 carrying the workpiece slowly dips into the dipping tank 4 under the action of the lifting track 3, the vertical moving frame 14 is first started and rises or falls by a certain distance, the position of the driving rod 11 in the vertical direction is adjusted, and the driving rod 11 is close to the height of the lifting ring 505 of the lifting tool 5. Then, the horizontal moving frame 15 starts to work and precisely positions the driving rod 11 in the horizontal transverse direction, so that the clamping portions 12 on the driving rod 11 engage with the toothed plate 13 on the lifting ring 505. Subsequently, the longitudinal moving frame 16 drives the driving rod 11 to move forward and backward, and due to the engagement relationship between the clamping portions 12 and the toothed plate 13, the toothed plate 13 starts to drive the lifting ring 505 to rotate under the pushing of the clamping portions 12, and the lifting ring 505 further drives the hanging bracket 504 and the whole workpiece to rotate uniformly in the dipping liquid. In the rotating process, each surface of the workpiece can fully contact with the dipping liquid, so that the thickness of the dipping layer is more uniform, thereby improving the dipping quality and protection performance of the product and reducing the rate of defective products caused by uneven dipping.

[0055] Further, a connecting rod 17 is swingably arranged on the hanger 504, and the hanger ring 505 is rotatably arranged on the connecting rod 17.

[0056] In the embodiment, at the moment when the clamping portion 12 on the driving rod 11 contacts the toothed plate 13 on the hanger ring 505, the connecting rod 17 is swingably arranged on the hanger 504, and the connecting rod 17 automatically swings slightly according to the slight impact force generated when the clamping portion 12 approaches, so as to effectively buffer the impact force generated at the moment when the clamping portion 12 contacts the toothed plate 13.

[0057] With the buffering of the connecting rod 17, the clamping portion 12 and the toothed plate 13 can smoothly mesh, and then the vertical moving frame 16 continues to move, drives the hanger ring 505 to rotate through the meshing relationship between the clamping portion 12 and the toothed plate 13, and the hanger ring 505 drives the workpiece to stably rotate in the plastic dipping liquid, so that the plastic dipping liquid uniformly wraps the surface of the workpiece.

[0058] Further, the clamping portion 12 is a vertical cylinder.

[0059] In the embodiment, at the moment when the clamping portion 12 contacts the toothed plate 13, the connecting rod 17 swings slightly to eliminate the impact force. In this process, even if the toothed plate 13 changes position due to the swing of the connecting rod 17, since the clamping portion 12 is a cylinder and has a relatively long length, the toothed plate 13 can still smoothly mesh with the clamping portion 12 after the swing, the circumferential surface of the clamping portion 12 can well adapt to the offset of the toothed plate 13, and the clamping portion 12 can still mesh with the toothed plate 13.

[0060] Further, the locking slot 9 has a V-shaped opening and faces downward.

[0061] In the embodiment, after the lifting device 5 is reset by rising along the lifting rail 3, the lifting device 5 needs to be reconnected with the driving chain 6, that is, the locking column 8 on the lifting device 5 needs to enter the locking slot 9 on the locking plate 7 of the driving chain 6. Since the locking slot 9 has a V-shaped opening and faces downward, even if there is a certain lateral deviation between the locking column 8 and the locking slot 9, the locking column 8 will first contact the edge of the V-shaped opening of the locking slot 9, and the guiding effect of the V-shaped opening will guide the locking column 8 to gradually slide along the inclined surface of the opening to the bottom of the locking slot 9, so as to realize accurate connection with the driving chain 6.

[0062] Further, the hanger ring 505 is V-shaped.

[0063] In the embodiment, when it is needed to install a hook on the hanger ring 505 to hang the workpiece, since the hanger ring 505 has a V-shaped structure, the connecting part of the hook is placed in the groove of the hanger ring 505, and the hook can keep a relatively fixed position in the hanger ring 505 and is not easy to fall off or deviate.

[0064] 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.
