Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to a flexible loading system and a cutting machine. Background Technology

[0002] With the booming development of the aluminum can market and the increasing demand year by year, competition in the industry is becoming increasingly fierce. This has prompted aluminum can manufacturers to continuously improve production efficiency, reduce the thickness of raw materials to save production costs, and develop increasingly diverse specifications and types of cans in order to have a stronger market competitiveness.

[0003] A can cutting machine is a device used to cut aluminum cans. It requires a raw can conveying system to guide the raw cans continuously into the cutting machine for cutting. Currently, the mainstream can conveying system on the market uses a cage-like form equipped with baffles and guide rails, allowing the uncut cans to roll vertically into the cutting machine using their own weight. However, this method has several problems in actual production. The cans collide with each other, easily causing compression deformation or dents, resulting in a high scrap rate. Furthermore, because the cans are transferred by their own weight, they enter the cutting mechanism of the cutting machine without any gaps. When the cutting mechanism runs at high speed, the cans are prone to blockage and jamming. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a flexible loading system and a cutting machine.

[0005] The solution to the technical problem of this utility model is: Firstly, a flexible receiving system is proposed, including: Mounting rack; The guide structure includes a first guide rail and a second guide rail, which are respectively connected to the mounting bracket. The first guide rail and the second guide rail are arranged along a first direction and together form a curved track. The upper and lower ends of the curved track are respectively provided with openings. An infeed star wheel is located below the guide structure and is rotatably connected to the mounting frame; The limiting structure includes a first baffle and a second baffle. The first baffle and the second baffle respectively cover both sides of the curved track along the second direction and are respectively connected to the mounting frame. The first direction and the second direction are perpendicular to each other and are respectively perpendicular to the up and down directions.

[0006] This utility model has at least the following beneficial effects: the cans to be processed enter from the top of the curved track and roll downward along the curved track under their own weight. During the fall, the side wall of the curved track can provide a buffer for the cans, avoiding deformation between adjacent cans due to squeezing or collision, thus improving the qualification rate of the can products; and the setting of the feeding star wheel allows the cans to be fed into the processing position one by one, making the transfer of cans more orderly and smooth, reducing the situation of can jamming and blockage.

[0007] As a further improvement to the above technical solution, the opposing sides of the first baffle and the second baffle are both polished surfaces.

[0008] As a further improvement to the above technical solution, the infeed star wheel includes a rotating shaft and a dial wheel. The dial wheel is sleeved on the outer periphery of the rotating shaft. The rotating shaft extends along a second direction and is rotatably connected to the mounting bracket. The dial wheel is provided with multiple blades, which are arranged around the circumference of the rotating shaft.

[0009] As a further improvement to the above technical solution, the flexible loading system also includes an arc-shaped guide rail, which is connected to the lower end of the second guide rail and extends from the upper side of the loading star wheel along the outer periphery of the loading star wheel to the lower side of the loading star wheel. The rotating shaft is located below the first guide rail, and an interval track is formed between the rotating shaft and the arc-shaped guide rail. The upper end of the interval track is connected to the lower end of the curved track.

[0010] As a further improvement to the above technical solution, the blade is provided with a first contact surface and a second contact surface. The first contact surface and the second contact surface are connected to each other at the ends away from the rotating shaft to form an insertion end. The insertion end is used to insert into two adjacent cans.

[0011] As a further improvement to the above technical solution, the first contact surface of one of the blades and the second contact surface of an adjacent blade together form an arcuate groove, and the groove wall of the arcuate groove matches the outer wall of the can.

[0012] As a further improvement to the above technical solution, the rotating shaft is detachably connected to the mounting bracket, and the dial is detachably connected to the rotating shaft.

[0013] As a further improvement to the above technical solution, the limiting structure further includes a guide post and a guide sleeve. The guide post extends along the second direction, one end of the guide post is connected to the mounting bracket, and the other end of the guide post is inserted into the guide sleeve and slidably connected to the inner wall surface of the guide sleeve to extend or retract into the guide sleeve. The guide sleeve is connected to the first baffle.

[0024] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. The various technical features of this utility model can be combined interactively without contradicting each other.

[0025] Firstly, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model embodiment proposes a flexible loading system, including a mounting frame 100, a guide structure, a limiting structure, and a loading star wheel 600. It can be applied to a cutting machine and can solve the problem of cans 900 squeezing and bumping against each other in the existing conveying system of the cutting machine, improve the product qualification rate, and avoid the problems of loading blockage and can jamming.

[0026] In this embodiment, the guiding structure includes a first guide rail 200 and a second guide rail 300, and the limiting structure includes a first baffle 400 and a second baffle 500. The first guide rail 200, the second guide rail 300, the first baffle 400, and the second baffle 500 are respectively connected to the mounting frame 100. The first guide rail 200 and the second guide rail 300 are arranged along a first direction, and the first guide rail 200 and the second guide rail 300 together form a curved track 201. The first baffle 400 and the second baffle 500 are respectively disposed on both sides of the curved track 201 along a second direction, and the upper and lower ends of the curved track 201 are respectively provided with openings. The loading star wheel 600 is disposed below the guiding structure and is rotatably connected to the mounting frame 100.

[0027] The first and second directions are set perpendicular to each other, and are respectively perpendicular to the up and down directions. For ease of description, the left and right direction will be referred to as the first direction, and the front and back direction as the second direction.

[0028] Understandably, the mounting bracket 100 provides installation space through its guide structure, limiting structure, and infeed star wheel 600. Both the first guide rail 200 and the second guide rail 300 extend vertically, with their opposing sides exhibiting a wavy shape and their sidewalls forming at least one S-shaped curved surface. This creates a curved track 201 between the first guide rail 200 and the second guide rail 300. The can 900 enters through the upper opening of the curved track 201. Under its own weight, the can 900 rolls downwards along the curved track 201. The sidewalls of the curved track 201 increase cushioning during the can 900's descent. Combined with the infeed star wheel 600, this effectively prevents squeezing and collisions between cans 900, maintaining the roundness of the can opening. Furthermore, the lower end of the curved track 201, through the action of the infeed star wheel 600, allows the cans 900 to be fed into the cutting machine one by one, making the transfer more orderly and smooth, reducing can jamming and blockage.

[0029] Understandably, the first baffle 400 and the second baffle 500 cover the front and rear sides of the curved track 201 to restrict the direction of movement of the can 900, ensure that the can 900 can roll downward on the curved track 201, and keep the can mouth side end face of each can 900 flush, so as to facilitate subsequent cutting processing.

[0030] In some embodiments, the opposing sides of the first baffle 400 and the second baffle 500 are both polished surfaces. The end face of the can 900 contacts the first baffle 400 and the second baffle 500. The smooth first baffle 400 and the second baffle 500 can reduce the resistance and scraping during the falling process of the can 900, and further avoid the situation of can jamming and stopping.

[0031] Specifically, in this embodiment, the first baffle 400 and the second baffle 500 are made of chrome-plated plates with polished surfaces.

[0032] In some embodiments, refer to Figure 5 The feed star wheel 600 includes a rotating shaft 620 and a dial wheel. The dial wheel is sleeved on the outer circumference of the rotating shaft 620, which extends in the front-to-back direction and is rotatably connected to the mounting bracket 100. The dial wheel is provided with multiple deflecting blades 610, which are arranged circumferentially around the rotating shaft 620. It can be understood that when the dial wheel rotates, the deflecting blades 610 can sequentially enter the curved track 201, separating adjacent cans 900 at the lower end of the curved track 201, thus achieving the effect of cans 900 entering the cutting machine one by one.

[0033] In this embodiment, the loading star wheel 600 has three leaflets 610.

[0034] In some embodiments, refer to Figure 4 The flexible loading system also includes an arc-shaped guide rail 700, which is connected to the lower end of the second guide rail 300. The upper side of the loading star wheel 600 extends along the outer periphery of the loading star wheel 600 to the lower side of the loading star wheel 600. The rotating shaft 620 is located below the first guide rail 200. The rotating shaft 620 and the arc-shaped guide rail 700 form an interval track 710. The upper end of the interval track 710 is connected to the lower end of the curved track 201.

[0035] Understandably, the arc-shaped guide rail 700 can guide the rolling direction of the can 900, allowing the can 900 to roll smoothly to the cutting mechanism of the cutting machine, and can work with the infeed star wheel 600 to limit the position of the can 900 when it rolls, further reducing the occurrence of collisions.

[0036] In this embodiment, when the dial rotates, the deflector blade 610 first enters the lower end of the curved track 201, separating two adjacent cans 900 at the lower end of the curved track 201. Driven by gravity, the cans 900 enter the spacer track 710. Within the spacer track 710, the cans 900 are separated by the deflector blade 610, preventing them from colliding and deforming. The gravity of the cans 900 drives the deflector blade 610 to continue rotating, and the cans 900 roll along the spacer track 710, entering the cutting mechanism of the cutting machine one by one.

[0037] In some embodiments, refer to Figure 4 and Figure 5The leaflet 610 is provided with a first contact surface 611 and a second contact surface 612. The ends of the first contact surface 611 and the second contact surface 612 away from the rotation axis 620 are connected to each other to form an insertion end 614. The insertion end 614 is used to insert between two adjacent cans 900. It can be understood that the distance between the first contact surface 611 and the second contact surface 612 gradually increases from the insertion end 614 towards the end of the rotation axis 620. After the insertion end 614 is inserted between the two cans 900, the distance between the two cans 900 will gradually increase to a preset spacing.

[0038] In some embodiments, the first contact surface 611 of a blade 610 and the second contact surface 612 of an adjacent blade 610 together form an arcuate groove 613. When the insertion end 614 of the blade 610 is inserted between two cans 900, the lower can 900 can enter the arcuate groove 613 corresponding to the first contact surface 611 of the blade 610. The upper can 900 contacts the second contact surface 612 of the blade 610. When the blade 610 rotates, the second contact surface 612 remains in contact with the outer wall of the upper can 900 until the can 900 enters the arcuate groove 613 corresponding to the second contact surface 612 of the blade 610. At this time, the insertion end 614 of the next blade 610 is inserted into the upper side of the can 900.

[0039] Understandably, the groove wall of the arc groove 613 matches the outer wall of the can 900. When the can 900 enters the arc groove 613, it can limit the shaking of the can 900 and further prevent the can 900 from bumping or hitting.

[0040] In some embodiments, the rotating shaft 620 is detachably connected to the mounting bracket 100, and the dial wheel is detachably connected to the rotating shaft 620. This configuration allows for quick changeover of the infeed star wheel 600, and operators can select a dial wheel of appropriate size based on the actual diameter of the can 900, resulting in greater versatility.

[0041] In some embodiments, refer to Figure 1 The limiting structure also includes a guide post and a guide sleeve 800. The guide post extends in the front-to-back direction, with one end connected to the mounting bracket 100 and the other end inserted into the guide sleeve 800 and slidably connected to the inner wall of the guide sleeve 800. The guide sleeve 800 is connected to the first baffle 400. It can be understood that the guide post can extend or retract into the guide sleeve 800, thereby adjusting the position of the first baffle 400 and changing the distance between the first baffle 400 and the second baffle 500 to accommodate tanks 900 of different lengths.

[0042] Understandably, the outer wall of the guide post and the inner wall of the guide sleeve 800 can slide relative to each other. The operator can adjust the length of the guide post extending out of the guide sleeve 800 by pushing and pulling, thereby changing the distance between the first baffle 400 and the second baffle 500, realizing rapid changeover, greatly improving the efficiency of changeover work, and reducing downtime.

[0043] In some embodiments, refer to Figure 1 and Figure 3 The first guide rail 200 includes two first guide plates 210, arranged front to back. The second guide rail 300 includes two second guide plates 310, also arranged front to back. It can be understood that the two first guide plates 210 are located on the front and rear sides of the inlet star wheel 600, respectively, and the two second guide plates 310 are located on the front and rear sides of the inlet star wheel 600, respectively. The dial of the inlet star wheel 600 can move in and out of the position between the two first guide plates 210 and reach the curved rail 201, separating the can 900 and making the installation structure between the guide structure and the inlet star wheel 600 more compact. Furthermore, the two first guide plates 210 and the two second guide plates 310 can support the front and rear ends of the can 900, which also contributes to the smooth entry of the can 900.

[0044] In some embodiments, the two first guide plates 210 and the two second guide plates 310 are respectively mounted on the mounting bracket 100 by screws. The operator can disassemble and replace the first guide plates 210 and the second guide plates 310 to change the width of the curved track 201 in the left and right directions, so as to accommodate the entry of tanks 900 of different diameters and achieve quick changeover.

[0045] It is understandable that the distance between the two first guide plates 210 and the distance between the two second guide plates 310 can be the same or different.

[0046] Secondly, this utility model embodiment proposes a cutting machine, which includes a flexible feeding system as described in any of the embodiments of the first aspect above. It is understood that the flexible feeding system is located at the inlet of the cutting machine. Due to the flexible feeding system, collisions between cans 90° are reduced, thereby improving product quality and accelerating changeover adjustments, saving downtime caused by changeovers.

[0047] In some embodiments, the cutting machine further includes a shearing star wheel 110 and a cutting mechanism. The cutting mechanism is positioned facing the shearing star wheel 110 and is capable of cutting the raw cans that enter the shearing star wheel 110. The shearing star wheel 110 is located at the exit of the spacer track 710. The raw cans separated by the infeed star wheel 600 can enter the cutting position of the cutting mechanism under the drive of the shearing star wheel 110, and the cutting mechanism cuts the raw cans.

[0048] The raw can rolls downwards along the curved track 201. The curved track 201 effectively reduces the impact between adjacent raw cans, preventing flattening of the raw cans due to compression on the wall surface and thus reducing roundness. It also effectively reduces bumps and scratches. When the raw can reaches the infeed star wheel 600, the infeed star wheel 600 separates the raw cans and feeds them one by one to the shearing star wheel 110. Driven by the shearing star wheel 110, the can enters the cutting position of the cutting mechanism to complete the mouth shearing operation. After the shearing action is completed, the can 900 leaves the cutting position under the action of the shearing star wheel 110 and is sent to the discharge track 120 of the cutting machine, where it is discharged to the next process. Figure 4 The installation positions of the shear star wheel 110 and the discharge track 120 are shown in the image.

[0049] After testing, it was found that due to the implementation of the flexible inbound system, the single-machine production speed of the cutting machine increased from 350 cans per minute to 500 cans per minute, greatly improving production efficiency.

[0050] Because the cutting machine adopts the aforementioned flexible feeding system, it also possesses all the beneficial effects brought about by the aforementioned flexible feeding system, which will not be elaborated upon here.

[0051] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
