[0037] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as there is no conflict between them.

[0038] Specific implementation method one: see Figures 1-9 Specifically, the feeding device for a heat transfer element rolling line according to the present application comprises a conveying platform 2, a pushing device 3, a guide device 4 and two rollers 5. The conveying platform 2 is connected to the guide device 4, and the guide device 4 is provided with two rollers 5 outside the outlet position at the end. The thin plate 1 is driven by a plurality of sets of synchronous pulleys arranged on the conveying platform 2 to move to the guide device 4. When the thin plate 1 moves to the guide device 4, the pushing device 3 and the thin plate 1 are in contact and push the thin plate 1 to move in the direction of the rollers 5. The pushing device 3 is arranged below the conveying platform 2 and the guide device 4. In the vertical direction, a part of the pushing device 3 overlaps the conveying platform 2, and the other part overlaps the guide device 4. The conveying platform 2 comprises a plurality of cantilever arms 6 and supports 7. The right half of the cantilever arm 6 is connected to the support 7, and the left half of the cantilever arm 6 is suspended and connected to the guide device 4. Synchronous pulleys are arranged on the cantilever arm 6, and a certain width is reserved between the cantilever arms 6. The pushing device 3 comprises two push hands 14, which are movably arranged at the upper end of the pushing device 3 and arranged in the gap between the cantilever arms 6. The push hands 14 can move back and forth in the gap left by the conveying platform 2 and the guide device 4 to push the thin plate 1.

[0039] The pushing device 3 further comprises a sliding table base 8, a sliding table 9, a sliding block 10, two transition frames 11 and two rotating cylinders 13. The sliding table 9 is arranged on the sliding table base 8, and the sliding table 9 is a high-precision sliding table. The main structure of the sliding table 9 is made of aluminum alloy. A high-rigidity lead screw is arranged on the sliding table 9, so that the sliding table 9 has small moving inertia and high-speed stability. The sliding block 10 is arranged on the lead screw. The lead screw is driven to rotate by a motor. The lead screw and the sliding block 10 are threadedly connected, so that the sliding block 10 moves forward and backward. One transition frame 11 is fixedly arranged on the sliding block 10 as a main transition frame by means of a flat key. The other transition frame 11 is slidably arranged on the sliding block 10 as a secondary transition frame. In operation, the position of the secondary transition frame is adjusted based on the main transition frame, so that the edges of the sheet 1 are kept parallel to the rolls 5 when the two transition frames 11 push the sheet 1 at the same time, thereby ensuring product quality. The rotating cylinder 13 is arranged on the transition frame 11 and connected with a pushing hand 14. The rotating cylinder 13 drives the pushing hand 14 to rotate, so that the pushing hand 14 is switched between an operating state and a non-operating state. The front end of the pushing hand 14 is provided with a magnet. When the pushing hand 14 contacts the stationary sheet 1, the magnet can be adsorbed to the sheet 1, thereby reducing the instability of the sheet 1. The rotating angle of the pushing hand 14 is 90 degrees. In operation, the pushing hand 14 is in a horizontal position. In the non-operating state, the pushing hand 14 is in a vertical position, as shown in FIG. 3. Figure 5

[0040] A lengthening rod 12 is arranged between the transition frame 11 and the rotating cylinder 13. The lengthening rod 12 is used to adjust the extension length of the pushing hand 14, so that the sliding table 9 does not interfere with the rolls 5 when the sheet 1 is short. The lengthening rod 12 is installed during the operation of processing short sheet materials and can be removed during the production of long sheet materials. The lengthening rod 12 and the transition frame 11 can be quickly positioned and installed through a positioning pin and a locking bolt.

[0041] Four adjusting mechanisms 17 are arranged at the bottom of the sliding table base 8. The adjusting mechanisms 17 adjust the level and height of the sliding table base 8, so that the relative height between the pushing hand 14 and the toothed belt of the synchronous pulley is consistent, and the relative positions among the sheet 1, the toothed belt and the pushing hand 14 are kept stable.

[0042] The guide device 4 comprises a support and a plurality of groups of guide structures. The plurality of groups of guide structures are arranged side by side on the upper end of the support 18, and a certain gap is left between adjacent two groups of guide structures. The gap is aligned with the gap between the cantilever 6, so that the pushing hand 14 can move forward and backward between the two gaps. One end of the guide structure is connected with the conveying platform 2, and the other end is provided with two rolls 5 on the outer side. The guide structure comprises two parallel guide plates 15. The guide plates 15 are mainly used to adjust the posture of the sheet 1 before entering the rolls 5, so that the sheet 1 smoothly enters the rolls 5.

[0043] ​The guiding structure further comprises several damping magnets 16 movably arranged between the two guiding plates 15, which adjust the magnetic force on the sheet 1 by adjusting the height to increase the friction between the sheet 1 and the guiding plates 15, so that the moving sheet 1 is smoothly and controllably stopped at the predetermined position. When the pusher 14 rapidly accelerates or decelerates to push the sheet 1, the sheet 1 has a certain damping, which prevents the sheet 1 from being thrown out due to inertia when the pusher 14 rapidly decelerates to stop (waiting for feeding the sheet 1 into the roller), thereby affecting the rolling effect. At the same time, the feeding time can also be greatly reduced. Three photoelectric switches are further arranged on the guiding device, which are used to detect three different positions of the sheet 1, so as to perform relevant actions at the corresponding positions, and finally feed the sheet 1 into the roller 5 at a fixed position to meet the production process requirements (i.e. the requirement for the wave: the starting positions of the waves of the sheets 1 of different lengths after being rolled into a certain shape are consistent, so the pusher 14 is required to feed the sheet 1 when the roller 5 rotates to a fixed angular position).

[0044] The sheet 1 is a thin steel sheet with a thickness of 0.5-1.2 mm, which is obtained by uncoiling, straightening and fixed-length shearing from a steel coil, and has a parallelogram or rectangular shape with a length ranging from 90-1050 mm and a width ranging from 300-1500 mm.

[0045] The specific working process of the feeding device special for the heat transfer element rolling line is explained as follows:

[0046] Firstly, the plate shearing machine cuts the coil into sheets 1 according to the feeding sequence, and the sheets 1 are sequentially dropped onto the conveying platform 2 and conveyed to the guiding device 4. The guiding device 4 is provided with three photoelectric switches, which are used to detect the positions of the sheets 1 and determine the next action. When the sheet 1 passes through the first photoelectric switch (sheet positioning detection switch), the pusher 3 receives the sheet positioning instruction, and the pusher 3 is switched from the initial state (the pusher 14 is in the falling state, and the sliding block 10 is in the rear end position) to the working state (the pusher 14 is lifted, and the sliding block 10 is started to move forward). When the sheet 1 reaches the second photoelectric switch (slow start point of the sliding block 10), the pusher 3 starts to move forward at a slow speed. At this time, the sheet 1 is located above the damping magnets 16 of the guiding device 4. Due to the combined force of the attractive force of the damping magnets 16 and the friction force of the guiding plates 15 being opposite to the movement direction of the sheet 1, the sheet 1 is closely attached to the magnets of the pusher 14 and is arranged. When the sheet 1 reaches the third photoelectric switch (stop and wait), the pusher 3 stops at this position and waits until the roller 5 rotates to the specified angular position, and then the pusher 3 feeds the sheet 1 into the roller 5 at a slow speed. After the above-mentioned actions are completed, the pusher 3 immediately retreats to the initial position at a high speed, the rotary cylinder 13 is reset, and the pusher 14 falls. While the pusher 3 retreats at a high speed, the second sheet 1 passes above the pusher 3, and the two achieve dynamic intersection, thereby greatly reducing the waiting time of each component and improving the production efficiency of the equipment.

[0047] Summarize the above implementation case, the heat transfer element rolling line special feeding device of the utility model, overcome the existing heat transfer element rolling production line produces many defective products and waste, the problem of low material comprehensive utilization rate, through the continuous conveying platform 2 carries thin plate 1, push hand 14 pushes thin plate to guide device to push roll 5, after the completion of a thin plate 1 push, immediately reset and push the next thin plate 1, realize the seamless connection of work cycle, dynamic cross between two work cycles, in the case where the first work cycle has not ended, the second work cycle has started, the feeding device production speed is 12 pairs / min on average, can reach 13-14 pairs / min at most, greatly improve production efficiency, the heat transfer element rolling line special feeding device of the utility model, the components involved in high-speed motion in push device all adopt lightweight design, select aluminum alloy material, reduce the number, volume and weight of moving parts, improve the rigidity of equipment while reducing the moving load, improve the stability of equipment, reduce motor load and starting time at the same time, greatly reduce the equipment load, energy consumption loss and failure rate, improve the production efficiency of equipment at the same time, the heat transfer element rolling line special feeding device of the utility model, through the guide device 4 set up, the deflection condition of thin plate 1 rolling process is greatly reduced, reduces the scrap rate, improves the comprehensive material utilization rate by 0.5% to a certain extent.
