Description

Technical Field

[0001] This invention relates to the field of can-making equipment technology, and specifically to a fully automatic feeding device for conveying can-making iron sheets to can-making equipment. Background Technology

[0002] In the can-making process, stacks of round or square can-making iron sheets (tinplate sheets) need to be continuously fed one by one to the feed rollers of the can-making equipment (such as the feed rollers of a can-making punch press) so that the subsequent can-making equipment can stamp and form the iron sheets.

[0003] Traditional sheet metal feeding methods often employ actuating suction cups or friction wheels, but existing sheet metal feeding structures suffer from the following problems during the feeding process:

[0004] 1) When using friction wheels to feed iron sheets, the friction wheels are prone to rigid contact and sliding friction with the surface of the iron sheets, which can easily scratch the surface of the iron sheets. The scratches on the surface of the iron sheets will directly affect subsequent processes, resulting in a decrease in product yield and economic losses.

[0005] 2) When using a toggle suction cup for feeding, after the suction cup picks up the iron sheet, it needs to be toggled by a horizontal lever to move the iron sheet out of the material pile. During this toggle process, the edge or surface of the iron sheet is very likely to scrape against the adjacent iron sheet or the side wall of the material pile, resulting in scratches on the surface of the iron sheet and affecting the appearance quality of the canned product. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to address the deficiencies of the existing technology by providing a fully automatic feeding device and method that uses a drive mechanism, a transmission mechanism and a pallet transmission mechanism in conjunction with a material suction and distribution structure to achieve fully automatic cyclic movement of the feeding pallet, without manual intervention, improving feeding stability, increasing production efficiency, improving the degree of feeding automation, avoiding scratches on iron sheets and ensuring feeding quality.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] On one hand, the present invention provides a fully automatic feeding device for distributing, absorbing, and feeding sheet metal for can making, including a fully automatic feeding device installed at the feed guide roller of the can making equipment. The fully automatic feeding device includes a work frame and a material absorption and distribution structure, a feeding tray, and a feeding drive structure fixed to the work frame.

[0009] The work frame has annular channels on both sides, and a feeding platform for storing several can-making iron sheets is provided below the work frame.

[0010] The material suction and distribution structure is installed inside the work frame and located above the feeding platform;

[0011] The material suction and distribution structure includes a lifting mechanism and a material suction and distribution mechanism. The lifting mechanism is fixed above the material suction and distribution mechanism, and the material suction and distribution mechanism is located above the feeding platform.

[0012] The feeding drive structure includes a drive mechanism, a transmission mechanism, and two sets of pallet transfer mechanisms. The drive mechanism is fixed to one side of the work frame and connected to the transmission mechanism. The two sets of pallet transfer mechanisms are respectively connected to both ends of the transmission mechanism and are arranged in an annular channel. The two sets of pallet transfer mechanisms are respectively connected to both ends of the feeding pallet to drive the feeding pallet to move.

[0013] Furthermore, the material suction and distribution mechanism includes a suction cup fixing plate and a plurality of suction discs. The top of the suction cup fixing plate is fixed to the lifting mechanism, and the plurality of suction discs are distributed at intervals along the bottom edge of the suction cup fixing plate. The top of the plurality of suction discs is connected to the bottom of the suction cup fixing plate.

[0014] Furthermore, the lifting mechanism includes a lifting drive component, a lifting fixed frame, a guide mechanism, and a suction cup lifting sensor. The lifting drive component is fixed to the middle of the lifting fixed frame, the guide mechanism is fixed to the lifting fixed frame and located on both sides of the lifting drive component, the telescopic rod of the lifting drive component extends downward and is connected to the suction cup fixing plate of the material suction and distribution mechanism to drive the suction cup fixing plate to rise and fall, and the suction cup lifting sensor is fixed at the lower end of the lifting fixed frame.

[0015] Furthermore, the guiding mechanism includes two sliding shafts and two linear bearings.

The drive motor is fixed to the work frame through the motor mounting base, and the motor shaft of the drive motor passes through the motor mounting base and is connected to the transmission mechanism.

[0017] Furthermore, the transmission mechanism includes a driving wheel, a driven wheel, a synchronous belt, and a chain drive shaft. The motor shaft of the drive motor is connected to the driving wheel. The driven wheel is sleeved in the middle of the chain drive shaft. The synchronous belt is sleeved on the driving wheel and the driven wheel. The driving wheel is connected to the driven wheel via the synchronous belt. The two ends of the chain drive shaft are respectively connected to two sprockets on both sides above the work frame.

[0018] Furthermore, each pallet conveying mechanism includes four sprockets and an annular conveying chain. The four sprockets are fixed at the four corners of the annular channel of the work frame.

[0020] On the other hand, the present invention also provides a fully automatic feeding method for distributing, sucking up, and feeding can-making iron sheets. The fully automatic feeding method, employing the aforementioned fully automatic feeding device, includes the following steps:

[0039] The present invention will now be described in detail with reference to the accompanying drawings, which form part of this specification. The principles of the invention are illustrated by means of embodiments, and other aspects, features, and advantages of the invention will become apparent from this detailed description. In the accompanying drawings, the same or similar parts in different figures are indicated by the same reference numerals.

[0040] like Figures 1-4As shown, Embodiment 1 of the present invention provides a fully automatic feeding device for distributing, absorbing, and feeding can-making iron sheets 6. This device includes a fully automatic feeding mechanism installed at the feed guide roller 71 of the can-making equipment 7. The fully automatic feeding device includes a work frame 1 and a suction and distribution structure 2, a feeding tray 3, and a feeding drive structure 4 fixed to the work frame 1. The work frame 1 has annular channels 11 on both sides, and a feeding platform 5 for storing several can-making iron sheets 6 is located below the work frame 1. The suction and distribution structure 2 is installed inside the work frame 1 and above the feeding platform 5. The suction and distribution structure 2 includes a lifting mechanism... The lifting mechanism 21 and the material suction and distribution mechanism 22 are provided. The lifting mechanism 21 is fixed above the material suction and distribution mechanism 22, which is located above the feeding platform 5. The feeding drive structure 4 includes a drive mechanism 41, a transmission mechanism 42, and two sets of pallet transmission mechanisms 43. The drive mechanism 41 is fixed to one side of the work frame 1 and connected to the middle of the transmission mechanism 42. The two sets of pallet transmission mechanisms 43 are respectively connected to both ends of the transmission mechanism 42 and are located in the annular channel 11. The two sets of pallet transmission mechanisms 43 are respectively connected to both ends of the feeding pallet 3 to drive the feeding pallet 3 to move. The present invention uses a lifting mechanism 21 to lower the material suction and distribution mechanism 22 onto the feeding platform 5. The material suction and distribution mechanism 22 then suctions the can-making iron sheet 6 on the feeding platform 5 to achieve the distribution of the can-making iron sheet 6. The lifting mechanism 21 then lifts the suction and distribution mechanism 22 to raise the suction and distribution mechanism 6. The driving mechanism 41 drives the transmission mechanism 42 to move the two sets of pallet transmission mechanisms 43. The two sets of pallet transmission mechanisms 43 move the empty feeding pallet 3 located at the upper end of the annular channel 11 along the annular path of the annular channel 11 to the lower part of the material suction and distribution structure 2 (i.e., the lower end of the annular channel 11). The material suction and distribution mechanism 22 places the suction and distribution mechanism 22 onto the feeding pallet 3. The driving mechanism 41 drives the transmission mechanism 42 to move the two sets of pallet transmission mechanisms 43 forward, so that the two sets of pallet transmission mechanisms 43 move the feeding pallet 3 containing the can-making iron sheet 6 to the feeding guide roller 71 of the can-making equipment 7. The fully automatic feeding device of this invention can sequentially pick up, lift and transfer the stacked can-making iron sheets 6 from the feeding platform 5 onto the feeding tray 3. The feeding tray 3 then conveys the can-making iron sheet 6 forward to the feeding guide roller 71 of the can-making equipment 7, realizing fully automatic feeding of the can-making iron sheet 6, reducing manual labor input, improving feeding efficiency, avoiding scratches on the can-making iron sheet 6 during the conveying process, protecting the can-making iron sheet 6, solving the problem of easy scratching of iron sheets in traditional push-type suction structures, and improving the stability of the can-making iron sheet 6 conveying process.

[0041] In this embodiment of the invention, the cross-section of the annular channel 11 is rectangular. The working frame 1 of the fully automatic feeding device serves as an integral support frame, which is welded from steel profiles and has sufficient rigidity and stability. The annular channel 11 set on both sides of the working frame 1 provides installation and operating space for the pallet transfer mechanism 43, and also serves to protect the pallet transfer mechanism 43.

[0042] The feeding platform 5 provided in this invention can be a liftable platform that automatically rises as the iron sheet is consumed, keeping the height of the top iron sheet constant, or it can be a fixed platform.

[0043] like Figure 5 As shown, in a specific implementation, the material suction and distribution mechanism 22 of the present invention includes a suction cup fixing plate 221 and a plurality of suction plates 222. The top end of the suction cup fixing plate 221 is fixed to the lifting mechanism 21. The plurality of suction plates 222 are distributed at intervals along the bottom edge of the suction cup fixing plate 221, and the top end of the plurality of suction plates 222 is connected to the bottom end of the suction cup fixing plate 221 to form a stable adsorption plane. The lifting mechanism 21 drives the suction cup fixing plate 221 and the plurality of suction plates 222 below it to descend, so that the plurality of suction plates 222 descend to the feeding platform 5, and the plurality of suction plates 222 suck up the can-making iron sheet 6 on the feeding platform 5 to realize the distribution of the can-making iron sheet; then the lifting mechanism 21 drives the suction cup fixing plate 221 and the plurality of suction plates 222 below it to rise, and lifts up the can-making iron sheet 6 sucked on the plurality of suction plates 222. The present invention arranges several suction cups 222 on the edge of the bottom end of the suction cup fixing plate 221. This distribution method can provide the most balanced adsorption force, and is particularly suitable for adsorbing square or rectangular iron sheet materials.

[0044] In this embodiment of the invention, each suction disc 222 is fixed with a pneumatic interface 223 on its side. Each suction disc 222 is connected to one end of an air pipe through the pneumatic interface 223, and the other end of the air pipe is connected to a vacuum pump. The vacuum pump provides negative pressure to several suction discs 222.

[0045] The lifting mechanism 21 of the present invention includes a lifting drive component 211, a lifting fixed frame 212, a guide mechanism 213, and a suction cup lifting sensor 214. The lifting drive component 211 is fixed to the middle part of the lifting fixed frame 212. The guide mechanism 213 is fixed on the lifting fixed frame 212 and located on both sides of the lifting drive component 211. The telescopic rod of the lifting drive component 211 extends downward and is connected to the suction cup fixing plate 221 of the material suction and distribution mechanism 22 so as to drive the suction cup fixing plate 221 to rise and fall. The suction cup lifting sensor 214 is fixed at the lower end of the lifting fixed frame 212. The guide mechanism 213 includes two sliding shafts 2131 and two linear bearings 2132. The two sliding shafts 2131 are symmetrically fixed on the lifting and fixing frame 212 and located on both sides of the lifting drive component 211. The two linear bearings 2132 are respectively sleeved on the two sliding shafts 2131 and can slide up and down along the sliding shafts 2131. The lower ends of the two sliding shafts 2131 extend downward and are connected to the suction cup fixing plate 221 of the material suction and distribution mechanism 22. The lifting and fixing frame 212 serves as the basic frame of the entire lifting mechanism 21, used to fix and support the lifting drive component 211, sliding shafts 2131, and other components, providing fixation and support for the entire lifting mechanism 21. The drive motor 411 is preferably a stepper motor, which has a fast response speed to control signals and can quickly start, stop, and reverse. The lifting drive component 211 is preferably a cylinder, which serves as the lifting drive source and is fixedly installed in the middle of the lifting and fixing frame 212 by bolts or other fasteners. The cylinder body of the lifting drive component 211 is fixed on the lifting fixed frame 212, and its telescopic rod passes downward through the bottom of the lifting fixed frame 212. The lifting drive component 211 realizes the lifting and lowering of the material suction and distribution mechanism 22 by extending and retracting the telescopic rod. The two sliding shafts 2131 are preferably optical shafts or guide rails. The two sliding shafts 2131 are symmetrically fixed on the lifting fixed frame 212 and located on both sides of the lifting drive component 211. The two sliding shafts 2131 cooperate with the linear bearing 2132 to form a precise guiding mechanism 213 to ensure that the lifting process is along the correct direction. In the vertical direction, two linear bearings 2132 are respectively sleeved on two sliding shafts 2131, and can slide freely up and down on the sliding shafts 2131, converting sliding friction into rolling friction, which greatly reduces motion resistance and ensures the smoothness and accuracy of lifting and lowering motion. During the lifting and lowering process, due to the constraint of the guide mechanism 213, the suction cup fixing plate 221 can only make precise vertical reciprocating motion along the sliding shaft 2131, effectively preventing it from deviating, twisting or jamming during the lifting and lowering process, and ensuring the accuracy of the position of the can-making iron sheet 6 being picked up and released.

[0046] The movement process of the lifting mechanism 21 driving the suction cup fixing plate 221 is as follows:

[0047] When it is necessary to raise several suction cups 222, the telescopic rod of the lifting drive component 211 extends downward. Since the cylinder body of the lifting drive component 211 is fixed on the lifting fixed frame 212, the telescopic rod will push the suction cup fixing plate 221 connected to it and several suction cups 222 below the suction cup fixing plate 221 to move downward as a whole. During the lifting and lowering process, the telescopic rod of the lifting drive component 211 will drive two linear bearings 2132 to slide downward synchronously along two sliding shafts 2131. The guide mechanism 213 composed of the sliding shafts 2131 and the linear bearings 2132 ensures that the suction cup fixing plate 221 and several suction cups 222 remain horizontal and stable during the descent.

[0048] When it is necessary to lower several suction discs 222, the telescopic rod of the lifting drive component 211 retracts upward, pulling the suction disc fixing plate 221, several suction discs 222 and linear bearing 2132 to move upward along the sliding shaft 2131, and rises smoothly under the constraint of the guide mechanism 213.

[0049] Regarding the material feeding and dispensing operation process of the material feeding and dispensing structure 2:

[0050] First, the telescopic rod of the lifting drive 211 extends downward, pushing the entire material suction and distribution mechanism 22 to descend vertically along the guide mechanism 213 until several suction discs 222 contact the surface of the can-making iron sheet 6 on the feeding platform 5. At this time, the external vacuum pump starts, causing negative pressure to be generated inside the suction discs 222, which firmly adsorbs the can-making iron sheet 6.

[0051] Subsequently, the telescopic rod of the lifting drive component 211 retracts upward, causing the material suction and distribution mechanism 22, which adsorbs the can-making iron sheet 6, to rise smoothly.

[0052] Finally, when the feeding pallet 3 is transported to the bottom of the suction mechanism by the pallet transfer mechanism 43, the vacuum is released, and the can-making iron sheet 6 of the suction mechanism is released onto the feeding pallet 3, completing one suction and transfer operation.

[0053] The present invention provides power for the lifting of the suction cup fixing plate 221 and several suction cups through the lifting drive component 211, and realizes the smooth operation of the lifting mechanism 21 by utilizing the high-precision guide mechanism 213 composed of symmetrically arranged sliding shafts 2131 and linear bearings 2132.

[0054] In other embodiments, the lifting drive 211 may also be an electric push rod, a combination of a stepper motor and a ball screw, etc.

[0055] like Figures 5-9As shown, in a specific implementation, the drive mechanism 41 of the present invention includes a drive motor 411 and a motor mounting base 412. The drive motor 411 is fixed to one side of the motor mounting base 412, and the transmission mechanism 42 is fixed to the other side of the motor mounting base 412. The drive motor 411 is fixed to the work frame 1 through the motor mounting base 412, and the motor shaft of the drive motor 411 passes through the motor mounting base 412 and is connected to the transmission mechanism 42. The transmission mechanism 42 includes a drive wheel 421, a driven wheel 423, a timing belt 422, and a chain drive shaft 424. The motor shaft of the drive motor 411 is connected to the drive wheel 421, the driven wheel 423 is sleeved in the middle of the chain drive shaft 424, the timing belt 422 is sleeved on the drive wheel 421 and the driven wheel 423, and the drive wheel 421 is connected to the driven wheel 423 through the timing belt 422. The two ends of the chain drive shaft 424 are respectively connected to two sprockets 431 on both sides above the work frame 1. The present invention drives the drive wheel 421 to rotate via the drive motor 411, and drives the driven wheel 423 and the chain drive shaft 424 to rotate under the transmission action of the synchronous belt 422.

[0056] In this embodiment of the invention, each pallet transfer mechanism 43 includes four sprockets 431 and annular transfer chains 432. The four sprockets 431 are fixed at the four corners of the annular channel 11 of the work frame 1. The annular transfer chains 432 are disposed within the annular channel 11 and are fitted around the four sprockets 431 at the four corners of the annular channel 11 and are engaged with the four sprockets 431. The two ends of the feeding pallet 3 are respectively connected to the sides of the annular transfer chains 432 of the two pallet transfer mechanisms 43. In specific implementation, among the pallet transfer mechanisms 43, the sprocket 431 located at the upper front of the annular channel 11 of the work frame 1 is the driving sprocket 431 (driven by the chain drive shaft 424), and the other three sprockets 431 are driven sprockets 431. The annular transfer chains 432 are made of stainless steel, and the tooth profile of the sprockets 431 matches the link of the annular transfer chains 432.

[0057] The motion principle of the feeding tray 3 is as follows:

[0058] Start the drive motor 411, which drives the drive wheel 421 to rotate. Under the transmission action of the synchronous belt 422, the drive wheel 423 and the chain drive shaft 424 on the drive wheel 423 rotate. Since the two ends of the chain drive shaft 424 are connected to the sprockets 431 located on both sides above the work frame 1, the power is directly transmitted to the two sprockets 431 through the chain drive shaft 424, causing the two sprockets 431 to rotate synchronously. During the rotation of the sprockets 431, the annular transmission chain 432 meshing with it will drive along the annular path. The circular path movement of channel 11 is such that, since the two ends of the feeding tray 3 are connected to the circular transmission chain 432 of the circular channel 11 on both sides of the work frame 1, when the circular transmission chain 432 moves in a circular motion, the feeding tray 3 will also move along with it, so that the feeding tray 3 moves to the suction and distribution mechanism 22, so that the can-making iron sheet 6 sucked on the suction and distribution mechanism 22 is transferred to the feeding tray 3, and then the feeding tray 3 transports the can-making iron sheet 6 to the feeding guide roller 71 of the can-making equipment 7, realizing the continuous cycle operation of feeding and empty return of the feeding tray 3.

[0059] The present invention uses a double-sided synchronous pallet transmission mechanism 43 to drive the feeding pallet 3 to move, which ensures the stability and accuracy of the feeding pallet 3 during the movement process, avoids problems such as deviation and jamming during the conveying of the can-making iron sheet 6, and ensures that the can-making iron sheet 6 carried on the feeding pallet 3 can be accurately delivered to the position of the feeding guide roller 71 of the can-making equipment 7.

[0060] This invention features tray guide rails 12 fixed at both the upper and lower ends of the annular channel 11, and chain guide rails 13 fixed at both the upper and lower ends of the annular channel 11, with the chain guide rails 13 mounted on the tray guide rails 12. The tray guide rails 12 inside the annular channel 11 facilitate the movement of the feeding tray 3 along the annular channel 11 by the annular transmission chain 432. The chain guide rails 13 inside the annular channel 11 facilitate the movement of the annular transmission chain 432 along the annular path of the annular channel 11 during the rotation of the sprocket 431. Specifically, this invention also features a chain limiting plate 14 fixed to the outer upper end of the annular channel 11. When the annular transmission chain 432 moves along the annular channel 11, the chain limiting plate 14 acts as a limit, preventing the annular transmission chain 432 from being thrown out of the annular channel 11 and improving operational safety.

[0061] The working process of the fully automatic feeding device in Embodiment 1 is as follows:

[0062] Initial state: The feeding tray 3 is located at the rear end of the upper part of the annular channel 11 of the work frame 1 (i.e., the position close to the operator).

[0063] Material suction and distribution: Activate the lifting drive component 211 of the material suction and distribution structure 2 to extend the telescopic rod of the lifting drive component 211, which drives several suction discs 222 to descend above the feeding platform 5. The suction discs 222 contact the uppermost can-making iron sheet 6 of the feeding platform 5. Activate the vacuum pump to generate negative pressure in the suction discs 222, which suck up the uppermost can-making iron sheet 6 of the feeding platform 5. Subsequently, the telescopic rod of the lifting drive component 211 retracts, which drives the suction discs 222 and the iron sheet they suck up to rise, realizing the vertical lifting of the can-making iron sheet 6 and completing the material suction and distribution action.

[0064] Material transfer: Drive motor 411 starts, driving drive wheel 421 to rotate. Under the transmission action of synchronous belt 422, driven wheel 423 and chain drive shaft 424 on driven wheel 423 to rotate. Chain drive shaft 424 drives two sprockets 431 to rotate synchronously. During the rotation of sprockets 431, the annular transmission chain 432 will move, causing the annular transmission chain 432 to move the empty feeding tray 3 from the rear end of the upper part of the annular channel 11 to the front end of the lower part of the annular channel 11, that is, to stop directly below the suction and distribution structure 2. Drive motor 411 is turned off, and feeding tray 3 stops moving.

[0065] Discharge: Several suction discs 222 of the suction and distribution structure 2 break the vacuum and smoothly release the can-making iron sheet 6 onto the feeding tray 3;

[0066] Feeding: The drive motor 411 starts again, driving the feeding tray 3 carrying the can-making iron sheet 6 to continue moving forward until the feeding tray 3 reaches the feeding guide roller 71 of the can-making equipment 7. The feeding guide roller 71 of the can-making equipment 7 will take over the can-making iron sheet 6 and send it into the stamping station. At the same time, the feeding tray 3, driven by the annular transmission chain 432, begins to return to the upper rear end starting position along the lower part of the annular channel 11, preparing for the next cycle.

[0067] Throughout the entire feeding process, the fully automatic feeding device ensures that the can-making sheet 6 only contacts the flat feeding tray 3, and there is no forced movement of any lateral parts. This perfectly avoids scratching the can-making sheet 6 and ensures the conveying quality of the can-making sheet 6.

[0068] The feeding tray 3 of the present invention includes a plurality of material-supporting shafts, which are spaced apart and arranged side by side between the annular transmission chains 432 of the annular channels 11 on both sides of the work frame 1. The two ends of each material-supporting shaft are respectively connected to the side of the annular transmission chains 432 of the annular channels 11 on both sides of the work frame 1. The feeding tray 3 adopts multiple material-supporting shafts arranged side by side at intervals, which can provide a stable support surface and is very suitable for the material-supporting and conveying of can-making iron sheets 6. Compared with the integral plate structure, the interval design saves more materials, reduces the overall weight, and lowers the manufacturing cost.

[0069] Embodiment 2 of the present invention provides a fully automatic feeding method for feeding 6-piece can-making iron sheets. The fully automatic feeding method employs a fully automatic feeding device for feeding, suction, and delivery of 6-piece can-making iron sheets. This fully automatic feeding method includes the following steps:

[0070] Step S1) The lifting mechanism 21 of the material suction and distribution structure 2 lowers the material suction and distribution mechanism 22 to the feeding platform 5, and the material suction and distribution mechanism 22 adsorbs the single sheet of can making iron 6 at the top of the feeding platform 5.

[0071] Step S2) The lifting mechanism 21 lifts the material suction and distribution mechanism 22, and lifts the can-making iron sheet 6 adsorbed by the material suction and distribution mechanism 22.

[0072] Step S3) Start the drive mechanism 41 of the feeding drive structure 4. The drive mechanism 41 drives the transmission mechanism 42 to move the two sets of pallet transfer mechanisms 43 to move the feeding pallet 3 located at the upper rear end of the annular channel 11 to the bottom of the suction and distribution structure 2.

[0073] Step S4) The material suction and distribution mechanism 22 of the material suction and distribution structure 2 releases the adsorbed can-making iron sheet 6, causing it to fall onto the feeding tray 3;

[0074] Step S5) The drive mechanism 41 of the feeding drive structure 4 drives the transmission mechanism 42 again, so that the transmission mechanism 42 drives the pallet transmission mechanism 43 to move, and transports the feeding pallet 3 carrying the can-making iron sheet 6 to the feeding guide roller 71 of the can-making equipment 7.

[0075] The fully automatic feeding method provided by this invention completes the entire process from material sorting and transfer to feeding automatically without human intervention. It has a high degree of automation, which greatly improves production efficiency, reduces the intensity of manual labor, and reduces labor costs.

[0076] Compared with the prior art, the technical solution disclosed in the above embodiments has the following beneficial effects:

[0077] In the above embodiments, the fully automatic feeding device of the present invention picks up the can-making iron sheet 6 through the suction and distribution structure 2, and the feeding tray 3 receives and transports the can-making iron sheet 6. During the entire process, no parts such as levers directly contact the surface of the can-making iron sheet 6, which effectively avoids the problem of scratching the can-making iron sheet 6 during the transportation process and ensures the aesthetic appearance of the canned product. In addition, through the cooperation of the drive mechanism 41, the transmission mechanism 42 and the tray transmission mechanism 43, the fully automatic cyclic movement of the feeding tray 3 can be realized. With the automatic suction action of the suction and distribution structure 2, no manual intervention is required, which improves the production efficiency of feeding.

[0078] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of this application. All equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
