Description

Technical Field

[0001] The present application relates to the technical field of tobacco packaging, and in particular to a feeding pusher connection structure. Background Art

[0002] In tobacco packaging, a rigid packing unit (such as the ZB48) includes a rigid strip and strip wrapper (such as the YB618). This unit features a feeder that pushes five rows of two-layer cigarette packs out of the pack elevator, through the sleeve, and into the turret.

[0003] In the current structure, the feeder pusher utilizes linear bearings mounted on two guide rods for linear motion, with its operation controlled by a cam. Specifically, the feeder pusher operates as a slider-crank mechanism, with the cam's rotational motion converted into linear motion by the slider, which then drives the feeder pusher in a linear reciprocating motion along the guide rods. After prolonged use, the feeder pusher experiences a vertical downward torque due to its own weight, and this applies uneven forces to the linear bearings and the two guide rods, causing significant wear on the guide rods and linear bearings. Furthermore, the feeder pusher may sag slightly, causing it to strike the sleeve during its reciprocating motion. This can cause defects and smoke at best, or even damage the equipment at worst.

[0004] How to improve the stability of the feeding pusher is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0005] In order to solve the above technical problems, the purpose of the present utility model is to provide a feeding pusher connection structure that can improve the stability of the feeding pusher.

[0006] The technical solutions provided by this utility model are as follows:

[0007] A feeding pusher connection structure is used to connect the feeding pusher so that the feeding pusher moves under the drive of a driving mechanism. The feeding pusher connection structure includes a fixing part, a connecting rod, and a rolling part. A guide rail groove is provided at the lower part of the fixing part. The lower end of the connecting rod is fixedly connected to the other end of the feeding pusher away from the guide rod, and the upper end is fixedly connected to the rolling part. The rolling part is accommodated in the guide rail groove so that the feeding pusher can move linearly along the guide rail groove.

[0008] Preferably, the rolling element includes a pin and two bearings. The pin is fixed to the upper end of the connecting rod, and the two bearings are respectively fixed on both sides of the pin.

[0009] Preferably, the rolling element further includes a plurality of snap rings, and the inner and outer sides of each bearing are fixed to the pin shaft via snap rings.

[0010] Preferably, on the fixing member, the length of the guide rail groove is equal to or slightly greater than the length of the guide rod, and the remaining part is a solid structure.

[0011] Preferably, both ends of the fixing member are respectively fixed on the equipment bracket.

[0012] Preferably, one end of the feeding pusher is movably connected to the guide rod and can move linearly along the guide rod under the drive of the driving mechanism, and the lower end of the connecting rod is fixedly connected to the other end of the feeding pusher away from the guide rod.

[0013] Compared to the existing technology, the feed pusher connection structure of the present invention is provided with a fixing member, a connecting rod, and a rolling member. The lower end of the connecting rod is fixedly connected to the feed pusher to restrain the feed pusher's tendency to move downward due to gravity. This can significantly improve the stability of the feed pusher, thereby improving the stability of cigarette pack forming and reducing the number of feed pusher interference blockages. At the same time, it ensures product quality and improves the stability of equipment operation. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0021] It should be noted that when an element is referred to as being “fixed on” or “set on” another element, it can be directly on the other element or indirectly set on the other element; when an element is referred to as being “connected to” another element, it can be directly connected to the other element or indirectly connected to the other element.

[0022] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0025] like Figures 1 to 5 As shown, this embodiment provides a feeding push handle connection structure. One end of the feeding push handle 1 is movably connected to a guide rod (not shown), and can move linearly along the guide rod under the drive of the driving mechanism 2 (the direction of movement is as shown in FIG. Figure 1 The driving mechanism 2 may adopt an existing structure, such as a cylinder.

[0026] The feeding pusher connection structure includes a fixing part 3, a connecting rod 4, and a rolling part 5. A guide rail groove 31 is provided at the lower part of the fixing part 3. The lower end of the connecting rod 4 is fixedly connected to the other end of the feeding pusher 1 away from the guide rod, and the upper end is fixedly connected to the rolling part 5. The rolling part 5 is accommodated in the guide rail groove 31, so that the feeding pusher 1 can move linearly along the guide rail groove 31. In this way, a virtual constraint is added by using the fixing part 3, the connecting rod 4, and the rolling part 5 to constrain the tendency of the feeding pusher 1 to move downward due to gravity, thereby significantly improving the stability of the feeding pusher, thereby improving the stability of cigarette pack forming, and reducing the number of interference and blockages caused by the feeding pusher. At the same time, product quality is guaranteed and the stability of equipment operation is improved.

[0027] In this embodiment, the rolling element 5 comprises a pin 51, two bearings 52, and multiple snap rings 53 (four in this embodiment). The pin 51 is fixed to the upper end of the connecting rod 4. The two bearings 52 are secured to the pin 51 via snap rings 53 mounted on the inner and outer sides. The bearings 52 enable the rolling element 5 to roll within the guide rail groove 31. Of course, in other embodiments, the rolling element 5 may employ other structures. In this embodiment, each bearing 52 is secured to the pin 51 via snap rings 53 on the inner and outer sides. Of course, in other embodiments, other structures may be employed to secure the bearings to the pin. However, the snap ring structure provides simplicity and ease of assembly and disassembly.

[0028] In this embodiment, the length of the guide rail groove 31 on the fixing member 3 is equal to or slightly greater than the length of the guide rod, and the remaining portion is a solid structure, so that the rigidity of the fixing member 3 is higher.

[0029] In this embodiment, both ends of the fixing member 3 are fixed to the equipment bracket 6. The equipment bracket 6 is generally fixed by punching holes on the wall panel and the body, and then the fixing member 3 is fixed by the equipment bracket 6 on both sides.

[0030] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
