For example, it can be a fixed connection, a replaceable connection, or an integral connection. It can be a mechanical connection or an electrical connection.

[0032] When the traditional vacuum drum adsorbs products, it can only adsorb products on the entire circumferential surface and cannot change the position of the adsorption holes. When adsorbing small products, there is a problem of air leakage, resulting in insufficient adsorption capacity. This embodiment provides a vacuum drum, which effectively solves the technical problem that the position of the adsorption holes of the existing vacuum drum cannot be changed.

[0033] Please refer to Figures 1 - 5 , this embodiment of the present application provides a vacuum drum, including a vacuum drum body 1, a magnet 3, and a baffle 2; a plurality of vacuum adsorption holes 5 are provided on the surface of the vacuum drum body 1; the magnet 3 is embedded on the surface of the vacuum drum body 1; a through hole 7 is provided on the baffle 2, and the baffle 2 is movably adsorbed on the surface of the vacuum drum body 1 through the magnet 3.

[0034] More specifically, the baffle 2 can be made of iron metal or iron-containing metal, and a magnet can be directly embedded on the baffle 2 so that the baffle 2 is magnetically attracted by the magnet 3 on the vacuum drum; in order to ensure that the baffle 2 can move left and right on the surface of the vacuum drum body 1, the baffle 2 only covers part of the vacuum adsorption hole 5, and the uncovered vacuum drum surface forms the movable range of the baffle 2; baffles 2 of different specifications can be configured, and the through holes 7 on baffles 2 of different specifications are of different sizes. By selecting baffles 2 with through holes 7 of different apertures, the purpose of adjusting the adsorption air intake of the vacuum drum can be achieved.

[0035] The present application achieves the purpose of adjusting the actual suction hole position of the vacuum drum, the range of the negative pressure area of ​​the vacuum drum and the suction air volume of the vacuum drum, so that the vacuum drum is suitable for products of different specifications, and effectively solves the technical problem that the suction hole position of the existing vacuum drum cannot be changed.

[0036] Furthermore, in this embodiment, a chip avoidance groove is provided on the baffle 2. The chip avoidance groove can protect the chip when the vacuum drum absorbs the Inlay product, so as to prevent the chip from being contacted and rubbed with the vacuum drum and thus reducing or damaging the performance of the Inlay product.

[0037] Furthermore, in this embodiment, the chip avoidance groove is staggered with the through hole 7. Such arrangement can prevent the chip avoidance groove from interfering with the normal air intake of the through hole 7.

[0038] Furthermore, in this embodiment, the surface of the vacuum drum body 1 is provided with a long hole milling groove 6, and the vacuum adsorption hole 5 is opened in the long hole milling groove 6. By providing the long hole milling groove 6 on the surface of the vacuum drum body 1, a feed position and a retracting position can be provided for a processing tool on the surface of the vacuum drum body 1, so that the processing tool can be conveniently processed into the vacuum adsorption hole 5 on the surface of the vacuum drum body 1.

[0039] Furthermore, in this embodiment, the magnet 3 is staggered with the long hole milling groove 6. By staggering the magnet 3 with the long hole milling groove 6, it is possible to avoid the magnet 3 interfering with the normal suction of the vacuum adsorption hole 5.

[0040] Furthermore, in this embodiment, a plurality of partition bars 4 are installed on the vacuum drum body 1, and the plurality of partition bars 4 are arranged in a circular manner on the surface of the vacuum drum body 1; an adsorption area is formed between every two adjacent partition bars 4, and the baffle 2 is movably installed in each adsorption area. The surface of the vacuum drum body 1 can be subdivided into a plurality of mutually independent adsorption areas by the arrangement of the partition bars 4, so as to install each baffle 2.

[0041] Further, in this embodiment, the outer surface of the baffle 2 protrudes from the outer surface of the partition strip 4, that is, the outer surface of the baffle 2 is exposed from the outer surface of the partition strip 4, creating a height difference between the baffle 2 and the partition strip 4, which is more convenient for the partition strip 4 to cooperate with the tool during operation. When the vacuum drum and the cutting device cooperate, the partition strip 4 can serve as a cutter pad for the tool of the cutting device, so that the tool can cooperate with the partition strip 4 to cut the product adsorbed on the surface of the vacuum drum.

[0042] More specifically, in order to reduce the damage of the tool to the partition strip 4, the partition strip 4 can be made of a harder material; and during the cutting operation, the cutting length of the product is exactly an integer multiple of the adsorption area, so that the cutting position of the tool each time falls on the partition strip 4.

[0043] Further, in this embodiment, a plurality of baffles 2 arranged in series and not connected to each other are distributed between two adjacent partition strips 4. By setting the plurality of non-connected baffles 2, the positions between two baffles 2 can also be areas not covering the vacuum adsorption holes 5 except at both ends, so that there are multiple arrangements of the baffles 2 in a single adsorption area. Through different arrangements of the baffles 2, the purpose of adjusting the actual adsorption hole position of the vacuum drum, the range of the negative pressure area of the vacuum drum, and the adsorption air intake of the vacuum drum can be well achieved.

[0044] Further, in this embodiment, the total length of the baffles 2 located in the same adsorption area is less than the length of the adsorption area. This setting ensures that there are positions in the adsorption area that do not cover the vacuum adsorption holes 5, thus facilitating the left and right movement of each baffle 2.

[0045] Further, in this embodiment, connecting shaft sleeves 8 are provided at both ends of the vacuum drum body 1. The provision of the connecting shaft sleeves 8 facilitates the installation of the entire vacuum drum on the rotating shaft, so that the driving device can drive the entire vacuum drum to rotate.

[0046] The various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts among the various embodiments can be referred to each other.

[0047] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
