[0032] like Figures 1 to 5 As shown, this embodiment provides a feeding device of a hot stamping machine, which is used to feed a plurality of stacked papers to be hot stamped. The stacked papers to be hot stamped are stacked on a paper supporting mechanism, and the paper supporting mechanism drags the papers upward.

[0033] Specifically, the loading device of the present embodiment includes a right box body 1 and a left box body 2 arranged relatively to each other, a second workbench 27 arranged at the front ends of the right box body 1 and the left box body 2, a paper supporting mechanism arranged between the right box body 1 and the left box body 2 and carrying a plurality of stacked papers to be stamped and moving upward, a first crossbeam 11 arranged between the right box body 1 and the left box body 2, two horizontal sliders 12 slidably arranged on the first crossbeam 11, a longitudinal slide bar 13 slidably arranged in the horizontal sliders 12 along the longitudinal direction and connected to the paper supporting mechanism at the lower part, an extrusion assembly 14 and a rear stop mechanism 15 arranged on the first crossbeam 11 and placed between the two horizontal sliders 12, an air pipe 16 arranged between the right box body 1 and the left box body 2, a plurality of hose connectors 17 arranged on the air pipe 16, slide grooves 20 respectively opened on the inner sides of the right box body 1 and the left box body 2, a first crank arm 18 respectively arranged on the right box body 1 and the left box body 2, and a second crank arm 18 having one end axially connected to the first crank arm 18. A crank arm 19, an air nozzle connecting beam 21 whose end slides along the slide groove 20 and is sleeved on the other end of the second crank arm 19, a plurality of first air nozzles 22 arranged on the air nozzle connecting beam 21 and connected to the hose connector 17 one by one, a third motor connected to the first crank arm 18, a third rotating shaft 23 and a driving travel shaft 26 rotated between the right box body 1 and the left box body 2, a fourth motor connected to the third rotating shaft 23, a fifth motor connected to the driving travel shaft 26, a third crank arm 24 with one end fixed on the third rotating shaft 23, an extrusion wheel 25 arranged at the other end of the third crank arm 24, two groups of first horizontal linear motion modules 28 and a single paper sliding feed slot plate 29 arranged on the second workbench 27, a transverse sliding support plate 30 arranged between the two groups of first horizontal linear motion modules 28, and a second air nozzle 31 arranged on the transverse sliding support plate 30 and adsorbing and transmitting the paper to be stamped in the single paper sliding feed slot plate 29.

[0034] The paper supporting mechanism includes a first lower rotating shaft 3 and a second upper rotating shaft 4 arranged at the rear ends of the right box body 1 and the left box body 2, a first sprocket 5 respectively arranged at the ends of the first lower rotating shaft 3 and the second upper rotating shaft 4, a chain 6 meshing with the first sprocket 5 on the same side of the first lower rotating shaft 3 and the second upper rotating shaft 4, a second driving motor arranged in the right box body 1 or the left box body 2 and connected to the first lower rotating shaft 3 or the second upper rotating shaft 4, a longitudinal slide rail slider assembly 7 respectively arranged on the inner side of the right box body 1 and the left box body 2 in the longitudinal direction, a support frame 8 fixed on the longitudinal slide rail slider assembly 7 and connected to the chain 6, a mounting plate 9 arranged on the support frame 8, and a shock-absorbing pad 10 arranged on the mounting plate 9 and supporting the paper to be stamped. The bottom of the longitudinal slide bar 13 is fixedly connected to the mounting plate 9.

[0035] In this embodiment, the first sprocket 5 drives the chain 6, the first lower rotating shaft 3 and the second upper rotating shaft 4, and drives the support frame 8, the mounting plate 9 and the shock-absorbing pad 10 to move along the longitudinal slide rail slider assembly 7, so that several stacked papers to be stamped move upward. After the first air nozzle 22 absorbs and transports the top layer of paper, the paper to be stamped moves upward to fill the position of the top layer of paper. During transportation, the first crank arm 18 drives the air nozzle connecting beam 21 to approach the paper supporting mechanism, and absorbs the paper to be stamped on the paper supporting mechanism one by one, and pushes and places it on the driving travel shaft 26. The single paper sliding feed slot plate 29 is connected to the driving travel shaft 26, and then the second air nozzle 31 is used to absorb the paper to be stamped in the paper feeding and discharging slot, and is pushed and moved by the first horizontal linear motion module 28.

[0036] Among them, the single paper sliding feed trough plate 29 includes a rectangular tray 291 fixed on the second workbench 27, a tray beam 292 arranged in the rectangular tray 291 and arranged along the direction of the first beam 11, and a plurality of lower limit bars 293 arranged at the bottom of the tray beam 292, and a paper feed and discharge slot is arranged between the lower limit bar 293 and the lower inner wall of the rectangular tray 291.

[0037] In this embodiment, the pressing assembly 14 presses the topmost layer of paper to be stamped, and cooperates with the first suction nozzle to ensure reliable paper adsorption. The pressing assembly 14 includes a cylinder mounting seat 141 fixed on the first crossbeam 11, a cylinder 142 arranged on the cylinder mounting seat 141 along the longitudinal direction, and a pressing block 143 arranged at the bottom of the cylinder 142. The pressing block 143 is placed above the paper supporting mechanism.

[0038] Since the paper to be stamped is relatively smooth, when the squeezing component 14 squeezes and the first suction nozzle contacts, the lower layer of paper may vibrate due to the squeezing, causing the paper to slide backwards, that is, several stacked papers are not laid out flush in the longitudinal direction, and there may be a problem of being unable to load the paper. Therefore, the present embodiment provides a rear stop mechanism 15 to support the rear ends of the stacked papers, which includes a support rod mounting seat 151 fixed on the first crossbeam 11, a support rod mounting plate 152 fixed on the support rod mounting seat 151 by a screw, a horizontal support rod 153 provided between the support rod mounting seat 151 and the support rod mounting plate 152 and arranged along the feeding direction of the paper to be stamped, a longitudinal support rod connecting slide 154 slidably sleeved on the horizontal support rod 153, a longitudinal support rod 155 provided at the bottom of the longitudinal support rod connecting slide 154, a cross bar 156 fixed in the middle on the longitudinal support rod 155 and arranged along the direction of the first crossbeam 11, and a plurality of rear extrusion blocks 157 provided on the cross bar 156. A locking knob is provided on the longitudinal support rod connecting slide 154. When placing several stacked papers, release the locking knob on the longitudinal support rod connecting the slide 154, lower the paper support mechanism, place the several stacked papers, raise the paper support mechanism, and move it to the position to be loaded. Then push the longitudinal support rod 155, the cross bar 156 and the rear extrusion block 157, so that the rear extrusion block 157 fits the rear end of the several stacked papers, and then use the locking knob to lock the longitudinal support rod connecting the slide 154.

[0039] The above embodiments are only preferred embodiments of the present utility model and are not intended to limit the protection scope of the present utility model. Any changes that adopt the design principles of the present utility model and are made through non-creative labor on this basis should fall within the protection scope of the present utility model.
