The filter rod compounding machine can realize the slitting and compounding of multiple filter rods. The compounded filter rods are then transported to the molding machine for docking. Since the transfer speed of the filter rods in the filter rod compounding machine is slow and cannot adapt to the material receiving speed of the molding machine, a special transfer mechanism is required between the two.

[0018] The following is a detailed description of an embodiment of the present invention in conjunction with the accompanying drawings. This embodiment is based on the technical solution of the present invention and provides a detailed implementation method, but the protection scope of the present invention is not limited to the following embodiment.
[0019] like Figure 1-3 As shown, the spider arm variable pitch adapter plate for the filter rod compound machine described in the present invention is composed of a spider arm bearing part, a motion guide part and an adsorption control part.
[0020] Specifically, the spider hand bearing portion includes a pair of rotating disks 1.1, a first mounting hole 1.2 for passing a driving shaft is provided at the center of the rotating disk 1.1, and a plurality of second mounting holes 1.3 are evenly provided on the periphery of the rotating disk 1.1; a rotating shaft 2.1 is passed through the second mounting hole 1.3, and a spider hand 3.1 located between the rotating disks 1.1 is sleeved and fixedly connected on the rotating shaft 2.1, and an adsorption groove 3.2 parallel to the axis of the rotating disk 1.1 is provided at the front end of the spider hand 3.1, the adsorption groove 3.2 is connected to an adsorption channel 3.3 located inside the spider hand 3.1 and extending backward, and the adsorption channel 3.3 is connected to a vacuum channel 2.2 provided on the rotating shaft 2.1. Normally, the vacuum channel 2.2 is an L-shaped structure with openings respectively provided on the side and bottom of the rotating shaft 2.1. A connecting rod 2.3 arranged parallel to the rotating disk 1.1 is installed at the other end of the rotating shaft 2.1 opposite to the vacuum channel 2.2, and a follower bearing 2.4 which is not coaxial with the rotating shaft 2.1 is installed on the connecting rod 2.3.
[0021] The motion guide part includes a fixed cam plate 4.1 installed on one side close to the follower bearing 2.4. A guide groove 4.2 is provided on the inner side of the fixed cam plate 4.1. The guide groove 4.2 is an annular groove with an inner concave structure 4.3. The follower bearing 2.4 is sleeved and installed in the guide groove 4.2. When the follower bearing 2.4 passes through the inner concave structure 4.3 of the guide groove 4.2, the fixed connecting rod 2.3 deflects, driving the rotating shaft 2.1 and the spider hand 3.1 to rotate accordingly, so that the spider hand 3.1 is connected with the transfer wheel for transporting the composite filter rod, and the filter rod is transferred at an accelerated speed under the action of vacuum adsorption.
[0022] The adsorption control unit includes a fixed negative pressure chamber 5.1 installed on one side of the vacuum channel of the rotating shaft 2.1, and a first negative pressure hole 5.2 corresponding to the moving track of the rotating shaft 2.1 is opened on the fixed negative pressure chamber 5.1. When the rotating shaft 2.1 moves to a position corresponding to the first negative pressure hole 5.2, under the action of negative pressure suction, the composite filter rod falling on the adsorption groove 3.2 at the front of the spider hand 3.1 is tightly adsorbed. When the rotating disk 1.1 moves to a position outside the first negative pressure hole 5.2, the composite filter rod will be desorbed due to the loss of negative pressure adsorption, but at the same time it will be adsorbed and grabbed by the transmission equipment of the next process.
[0023] When the rotating shaft 2.1 rotates along the fixed negative pressure chamber 5.1 for a long time, the fixed negative pressure chamber 5.1 will be damaged due to friction. Therefore, a wear-resistant disk 6.1 is usually installed between the rotating disk 1.1 and the fixed negative pressure chamber 5.1, and a second negative pressure hole 6.2 corresponding to the position of the first negative pressure hole 5.2 is opened on the wear-resistant disk 6.1.
[0024] It should be noted that the rotating disk 1.1, the fixed cam disk 4.1, the fixed negative pressure chamber 5.1 and the wear-resistant disk 6.1 are all coaxially arranged, and the starting end of the first negative pressure hole 5.2 corresponds to the concave structure 4.3 of the guide groove 4.2.
[0025] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “front”, “rear”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.
