The same reference numbers in the drawings represent the same elements or similar elements. Although various aspects of the embodiments are illustrated in the drawings, the drawings are not necessarily drawn to scale unless specifically indicated.

[0023] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any implementation described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations.

[0024] In addition, for the purpose of better illustrating the present application, numerous specific details are given in the following specific embodiments. Those skilled in the art should understand that the present application can also be implemented without some specific details. In some examples, methods, means, elements well known to those skilled in the art are not described in detail, so as to highlight the main idea of the present application.

[0025] Please refer to Figures 1-4 As a transverse single pushing and double pushing mechanism of a middle package machine, the utility model discloses a pushing structure, the pushing structure includes: mounting plate 2, fixed on workbench 1, rectangular ring groove 5 is formed on mounting plate 2, fixed piece 7 moves along rectangular ring groove 5 and is guided by two-dimensional guide 4 mounted on mounting plate 2, pushing unit moves synchronously with fixed piece 7, driving part is installed on mounting plate 2 and is used to drive fixed piece 7 to move to drive pushing unit to move along meandering trajectory.

[0026] In the embodiment, the driving member cooperates with the rectangular ring groove 5 and the two-dimensional guide 4 to enable the fixing member 7 to drive the pushing unit to move along the meandering trajectory stably, to realize the transverse pushing of the paper towel package, and to enable the pushing unit to return to the initial position quickly after pushing the last group of paper towel packages, so as to prepare for the next pushing and not to interfere with the movement of the next group of paper towel packages, thereby improving the work efficiency, and the rectangular ring groove 5 limits and guides the movement of the fixing member 7, to ensure the accuracy of the movement trajectory.

[0027] Further, referring to Figure 2 and Figure 4 , the driving member comprises a driving source 3, an output shaft of the driving source 3 is connected with a driving shaft 12 which is rotatably installed on the mounting plate 2, an oscillating connecting rod 6 is fixed on the driving shaft 12, and the oscillating connecting rod 6 is movably connected with the fixing member 7; the oscillating connecting rod 6 is formed with a slot hole 601 along the length direction thereof, the fixing member 7 is fixed with a connecting shaft 11 which can penetrate through the slot hole 601, and a roller 10 located in the rectangular ring groove 5 is rotatably installed on one end of the connecting shaft 11 which extends into the rectangular ring groove 5.

[0028] When the driving source 3 is started, the driving shaft 12 is driven to rotate, thereby driving the oscillating connecting rod 6 fixed thereon to oscillate along the circumference, when the oscillating connecting rod 6 oscillates, the connecting shaft 11 is limited by the slot hole 601, and the roller 10 on the connecting shaft 11 is located in the rectangular ring groove 5, so that the oscillating connecting rod 6 drives the fixing member 7 to move in the oscillating process, thereby avoiding the possible jamming or poor movement due to the rigid connection.

[0029] Meanwhile, the two-dimensional guide 4 is arranged, so that the fixing member 7 does not rotate when moving, thereby enabling the fixing member 7 to move stably along the predetermined meandering trajectory in the two-dimensional plane, and the two-dimensional guide 4 changes the position adaptively when the fixing member 7 moves, to drive the pushing unit to perform the meandering trajectory movement.

[0030] The roller 10 is arranged, so that the roller 10 rolls in the rectangular ring groove 5, to reduce the friction when the fixing member 7 moves, and to reduce the generation of vibration and noise.

[0031] The driving source 3 can be selected according to the actual needs, such as a motor, and the like, and thus the embodiment will not be described in detail.

[0032] It should be noted that the length of the slot hole 601 is greater than the diameter of the connecting shaft 11, so that the fixing member 7 can displace relative to the oscillating connecting rod 6, to ensure that the oscillating connecting rod 6 can drive the fixing member 7 to move when oscillating to different angles.

[0033] Further, referring to Figure 3The two-dimensional guide 4 comprises a first guide rail 401 fixed on the mounting plate 2, a connecting seat 403 with a first sliding block 402 and a second sliding block 404 fixed on two sides, the first sliding block 402 being in sliding connection with the first guide rail 401, and a second guide rail 405 in sliding connection with the second sliding block 404, wherein the pushing unit and the fixing member 7 are both fixed with the second guide rail 405.

[0034] When the driving source 3 drives the driving shaft 12 to rotate, the swing connecting rod 6 swings to drive the fixing member 7 to move, the first sliding block 402 slides on the first guide rail 401, and the second sliding block 404 slides on the second guide rail 405, so that the two-dimensional guide 4 can flexibly adapt to the movement of the fixing member 7, and ensure that the pushing unit moves along the accurate meandering track.

[0035] The pushing unit comprises a connecting frame 8 transversely arranged and fixed at one end with the second guide rail 405, and the other end of the connecting frame 8 is fixed with a pushing member 9, wherein the pushing member 9 in the embodiment is a common pushing structure in the existing bag machine, and thus the embodiment will not be described in detail.

[0036] As another embodiment of the utility model, please refer to Figures 5-7 When the pushing structure is provided with two pushing units, the two pushing units alternately perform the pushing action under the phase difference of the respective meandering tracks, and the mounting plates 2 of the two pushing structures are fixed through a plurality of fixing frames 14.

[0037] Specifically, when the pushing structure is provided with two pushing units, the driving shafts 12 of the two pushing structures are fixed through a fixed connecting shaft 13, the fixed connecting shaft 13 is connected with the driving source 3 through a transmission belt, the driving source 3 can simultaneously drive the two driving shafts 12 to synchronously rotate, so as to ensure that the phase difference between them is stable and unchanged, and the driving source 3 in the embodiment is arranged between the two mounting plates 2.

[0038] In detail, under the phase difference of the respective meandering tracks, when one pushing unit performs the pushing action, the other pushing unit is in the state of returning to the initial position or preparing for pushing, so as to alternately perform the pushing action and alternately push, thereby effectively improving the overall work efficiency.

[0039] It is apparent for a person skilled in the art that the present application is not limited to the details of the above-described exemplary embodiments, but that it can be implemented in other concrete forms without departing from the spirit or the essential characteristics of the present application.
