[0033] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0035] It should be noted that the terms "large diameter" and "small diameter" used herein are intended only to describe cans of varying diameters. They are not intended to limit the specific dimensions of cans, nor should they be construed as unclear or insufficiently disclosed. The technical solution of this application arises from the fact that cans of varying diameters have varying degrees of necking. Furthermore, the necking station discussed herein is prior art and, as it is not the focus of this application, its structure will not be further elaborated.

[0036] What needs to be understood is that purchasing goods from the middle does not necessarily mean purchasing from the exact middle. The middle is a relative concept.

[0037] See also Figure 1 、 Figure 2 and Figure 3 The embodiment of the present invention provides an intermediate loading device for necking and flanging cans, comprising a loading mechanism 1, a wax coating mechanism 2, and a transfer mechanism 3; the loading mechanism 1 is connected to the wax coating mechanism 2, and the wax coating mechanism 2 is connected to the transfer mechanism 3; the loading mechanism 1, the wax coating mechanism 2, and the transfer mechanism 3 form an intermediate loading station 4;

[0038] The loading mechanism 1 includes a loading flange 5 and a feeding turret 6; the unnecked can body is conveyed to the feeding turret 6 via the loading flange 5;

[0039] The wax coating mechanism 2 includes a wax coating main wheel 7, a wax coating ring gear 8, a wax coating sub-wheel 9 and a wax coating rubber roller 10; the feed turret 6 transports the can body to the wax coating station of the wax coating main wheel 7, the wax coating ring gear 8 and the wax coating sub-wheel 9 constitute a planetary gear train, and the wax coating rubber roller 10 is distributed at the wax coating station of the wax coating main wheel 7; the wax coating sub-wheel 9 drives the wax coating rubber roller 10 to drive the can body at the wax coating station;

[0040] The transfer mechanism 3 includes a transfer star wheel 11. The wax coating main wheel 7 transports the waxed can body to the transfer star wheel 11, and the can body is transferred to the necking station through the transfer star wheel 11.

[0041] Assist Figure 1 In this embodiment, the loading mechanism 1 and the wax coating mechanism 2 share a loading and waxing machine base 12. The loading mechanism 1 also includes a feed gear 13, a feed wheel shaft 14, a feed wheel bracket 15, and a mounting plate 16. The feed gear 13 is located on one side of the loading and waxing machine base 12, and the feed wheel shaft 14 is connected to the feed gear 13. The feed wheel shaft 14 passes through the loading and waxing machine base 12 and the feed wheel bracket 15. The mounting plate 16 is connected to the feed wheel bracket 15. The loading flange 5 is connected to the mounting plate 16. The feeding turret 6 is connected to the feeding wheel shaft 14. The loading mechanism 1 also includes a guard plate 17, which is connected to the mounting plate 16 via a positioning support 18. The feeding turret 6 is located in the gap between the guard plate 17 and the mounting plate 16. The waxing mechanism 2 also includes a waxing gear 19, a waxing wheel axle 20, and a waxing wheel bracket 21. The waxing gear 19 is located on one side of the incoming waxing machine base 12 and meshes with the feed gear 13. The waxing wheel axle 20 connects to the waxing gear 19 and passes through the incoming waxing machine base 12 and the waxing wheel bracket 21. The waxing main wheel 7 is connected to the waxing wheel axle 20. The guard plate 17 extends along the edge of the waxing main wheel 7 to the bottom of the waxing main wheel 7, and the mounting plate 16 also extends along the edge of the waxing main wheel 7 to the bottom of the waxing main wheel 7. The waxing mechanism 2 also includes a waxing baffle 22, which is connected between the guard plate 17 and the mounting plate 16. The waxing baffle 22 is connected to a waxing contact 23, which is connected to the waxing baffle 22 and is distributed outside the waxing station of the waxing main wheel 7. The wax coating contact 23 is provided with a cotton strip containing lubricant, and the wax coating sub-wheel 9 drives the wax coating rubber roller 10 to rotate the can body at the wax coating station; the can body at the wax coating station of the wax coating main wheel 7 contacts the cotton strip containing lubricant to be waxed.

[0042] The unnecked can body enters through the loading flange 5, with the can mouth facing inward. The can body is vacuum-sucked into the arc-shaped station of the feed turret 6. After rotating half a revolution with the feed turret 6, the can body is transferred to the waxing station corresponding to the waxing main wheel 7. Because the waxing sub-wheel 9 and the fixed waxing ring gear 8 form a planetary gear system, when the waxing main wheel 7 rotates, the waxing rubber roller 10, which is coaxial with the waxing sub-wheel 9, rotates simultaneously. As a result, the can body, vacuum-sucked on the waxing rubber roller 10, rotates with it. The outer surface of the can mouth contacts and slides against the wax liquid (lubricant, continuously supplied from the outside) sliver inside the waxing contact 23, coating the outer surface of the can mouth with the wax liquid. The coverage of the sliver ensures that the can mouth is coated for at least one revolution. After the waxing process is completed, the can body rotates below the waxing main wheel 7 and is then transferred to the transfer star wheel 11.

[0043] See also Figure 2In this embodiment, the transfer mechanism 3 further includes a transfer gear 24, a transfer axle 25, a transfer seat 26, and a transfer shaft frame 27. The transfer gear 24 is connected to the transfer axle 25, which passes through the transfer seat 26 and the transfer shaft frame 27. The transfer seat 26 is connected to the transfer shaft frame 27. The transfer star wheel 11 is connected to the transfer axle 25. The transfer star wheel 11 is also connected to an air distribution disk 28, which is connected to a vacuum connector 29.

[0044] Specifically, for the unnecked can body (small diameter) entering from the loading mechanism 1, after waxing, the waxing main wheel 7 will be rotated to the transfer star wheel 11, and the air distribution plate 28 and the vacuum joint 29 will use vacuum to adsorb the can body to the arc work station of the transfer star wheel 11. After the can body rotates 1 / 3 of a circle with the transfer star wheel 11, it will be handed over to the transfer wheel of the docking necking station.

[0045] Among them, for the can body (large diameter) that has been partially necked from the upstream necking station, it will be transferred from the corresponding passing wheel to the transfer star wheel 11, and the can body will be adsorbed into the arc work station of the transfer star wheel 11 by using vacuum. After the can body rotates 2 / 3 of a circle with the transfer star wheel 11, it will be handed over to the passing wheel of the next necking station.

[0046] Assist Figure 3 In this embodiment, a limiting mechanism 30 is also included, which includes a limiting seat plate 31, a linear guide rail 32, an adjusting slider 33, an adjusting slide 34, an adjusting frame 35, a movable baffle 36 on the tank bottom and a fixed baffle 37 on the tank mouth; the linear guide rail 32 is distributed at the upper end of the limiting seat plate 31, the adjusting slider 33 is connected to the linear guide rail 32, the adjusting slide 34 is connected to the adjusting slider 33, the lower end of the adjusting frame 35 is connected to the adjusting slide 34, the upper end of the adjusting frame 35 is connected to the movable baffle 36 on the tank bottom, the fixed baffle 37 on the tank mouth and the movable baffle 36 on the tank bottom are distributed outside the transfer station of the transfer star wheel 11; the distance between the movable baffle 36 on the tank bottom and the fixed baffle 37 on the tank mouth is changed by the adjusting frame 35, so that the transfer station of the transfer star wheel 11 can adapt to cans of different lengths. The limiting mechanism 30 further includes a limiting frame 38 , which is connected to the end of the linear guide rail 32 . The limiting frame 38 blocks the adjusting slide 34 on the adjusting slider 33 .

[0047] Specifically, a limiting mechanism 30 is provided to ensure the stability of the can body's axial position on the transfer star wheel 11 and enable normal can loading at the downstream necking station. Because the can mouth's axial position is relatively fixed, the fixed baffle 37 at the can mouth does not require frequent adjustment after initial installation. The movable baffle 36 at the can bottom slides axially on the linear guide 32 along with the adjustment bracket 35, adjustment slide 34, and adjustment slider 33, and can be fixed at any position within the permitted range to accommodate the production of can bodies of varying lengths.

[0048] Assist Figure 4 、 Figure 5 and Figure 6Through the technical solution of the present invention, the present technical solution can be added as an intermediate loading station 4 at the appropriate position of the original necking station of the necking and flanging machine according to the number of necking stages required for small-diameter cans. The intermediate loading station 4 has the functions of loading, waxing, and transmission, and the transfer gear 24 can slide axially to control the transmission and cutting of power. When producing large-diameter cans, the product cans enter from one end of the equipment and simply pass through the intermediate loading station 4. When producing small-diameter cans, the product cans bypass the useless necking stations and enter directly from the entrance of the intermediate loading station 4. After completing the necessary number of necking stages, they enter the flanging and subsequent processes. In this way, when producing small-diameter cans, it is only necessary to disassemble and assemble the conversion parts at the necessary functional stations, saving the investment cost of the conversion parts and the conversion time; and the transfer gear 24 of the intermediate loading station 4 can be slid out of position to stop the useless functional stations upstream from rotating, thereby saving energy consumption.

[0049] In summary, the present invention is provided with a loading mechanism 1, a wax coating mechanism 2 and a transfer mechanism 3; the loading mechanism 1 is connected to the wax coating mechanism 2, and the wax coating mechanism 2 is connected to the transfer mechanism 3; the loading mechanism 1, the wax coating mechanism 2 and the transfer mechanism 3 form an intermediate loading station 4; the loading mechanism 1 includes a loading flange 5 and a feeding turret 6; the unnecked can body is transported to the feeding turret 6 through the loading flange 5; the wax coating mechanism 2 includes a wax coating main wheel 7, a wax coating gear ring 8, a wax coating sub-wheel 9 and Wax coating rubber roller 10; the feeding turret 6 transports the can body to the wax coating station of the wax coating main wheel 7, the wax coating ring gear 8 and the wax coating sub-wheel 9 constitute a planetary gear system, and the wax coating rubber roller 10 is distributed at the wax coating station of the wax coating main wheel 7; the wax coating sub-wheel 9 drives the wax coating rubber roller 10 to drive the can body at the wax coating station; the transfer mechanism 3 includes a transfer star wheel 11, and the wax coating main wheel 7 transports the waxed can body to the transfer star wheel 11, and the can body is handed over to the necking station through the transfer star wheel 11. The unnecked can body enters through the loading flange 5, with the can mouth facing inward. The can body is vacuum-sucked into the arc-shaped station of the feed turret 6. After rotating half a revolution with the feed turret 6, the can body is transferred to the waxing station corresponding to the waxing main wheel 7. Because the waxing sub-wheel 9 and the fixed waxing ring gear 8 form a planetary gear system, when the waxing main wheel 7 rotates, the waxing rubber roller 10, which is coaxial with the waxing sub-wheel 9, rotates simultaneously. As a result, the can body, vacuum-sucked on the waxing rubber roller 10, rotates with it. The outer surface of the can mouth contacts and slides against the wax liquid (lubricant, continuously supplied from the outside) on the inside of the waxing contact 23, coating the outer surface of the can mouth with the wax liquid (lubricant, continuously supplied from the outside). The wax liquid is then applied to the outer surface of the can mouth, with the coverage of the waxing sliver ensuring at least one revolution of the can mouth. After the waxing process is completed, the can body is transferred below the waxing main wheel 7 and then transferred to the transfer star wheel 11. For unnecked can bodies (small diameter) entering from the loading mechanism 1, after waxing, they will be transferred from the waxing main wheel 7 to the transfer star wheel 11. The air distribution plate 28 and vacuum joint 29 use vacuum to absorb the can body into the arc position of the transfer star wheel 11. After the can body rotates 1 / 3 of a circle with the transfer star wheel 11, it is transferred to the transfer wheel of the docking necking station. For can bodies (large diameter) that have been partially necked from the upstream necking station, they will be transferred from the corresponding transfer wheel to the transfer star wheel 11. The can body is sucked into the arc position of the transfer star wheel 11 using vacuum. After the can body rotates 2 / 3 of a circle with the transfer star wheel 11, it is transferred to the transfer wheel of the next necking station. In order to ensure the stability of the can body's axial position on the transfer star wheel 11 and enable normal can loading at the downstream necking station, a limiting mechanism 30 is provided. Because the axial position of the can mouth is relatively fixed, the fixed baffle 37 of the can mouth does not require frequent adjustment after initial installation. The movable baffle 36 at the can bottom can slide axially on the linear guide 32 along with the adjustment frame 35, the adjustment slide 34, and the adjustment slider 33, and can be fixed at any position within the allowable range to accommodate the production of can bodies of different lengths. This invention improves the efficiency of can conversion, saves auxiliary labor, reduces the investment in conversion parts, and significantly reduces energy consumption in the production of small-diameter cans.

In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
