[0016] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.
[0017] The utility model discloses a PET film automatic winding machine, combined with Figures 1 to 3 As shown, it comprises a frame 1, a front end plate 2 is fixed to the front side of the frame 1, and a paper tube taking and placing mechanism 3, a paper tube pushing mechanism 4, a front and rear lateral movement mechanism 5 and a lifting and receiving material mechanism 6 are arranged on the frame 1, wherein:
[0018] The front end plate 2 is provided with an opening 20;
[0019] The paper tube pushing mechanism 4 is used to push the paper tube 100 to the material taking end of the paper tube taking and placing mechanism 3;
[0020] The paper tube picking and placing mechanism 3 is used to pick up the paper tube 100 and transfer the paper tube 100 laterally to the front side of the opening 20;
[0021] The moving end of the front-to-back transverse movement mechanism 5 is provided with a winding roller shaft 7, and the front-to-back transverse movement mechanism 5 is used to drive the winding roller shaft 7 to move forward and insert the paper roll 100 at the front side of the opening 20;
[0022] The winding roller 7 is used to drive the paper roll 100 to rotate to wind up the PET film;
[0023] The lifting material receiving mechanism 6 is located below the winding roller shaft 7, and the lifting material receiving mechanism 6 is used to support the material roll of the wound PET film.
[0024] During the operation of the winding machine, the paper roll 100 is first placed on the paper roll pushing mechanism 4, and the paper roll 100 is pushed to the material-receiving end of the paper roll picking and placing mechanism 3 by the paper roll pushing mechanism 4. After the paper roll picking and placing mechanism 3 picks up the paper roll 100, the paper roll picking and placing mechanism 3 moves horizontally to the left and right and moves the paper roll 100 horizontally to the front center position of the opening 20. Since the winding roller shaft 7 is aligned with the center position of the opening 20, when the front-back lateral movement mechanism 5 drives the winding roller shaft 7 to move forward, the paper roll 100 is moved horizontally to the front center position of the opening 20. During the movement, the winding roller 7 can pass through the opening 20 and be plugged into the paper roll 100, and then the paper roll taking and placing mechanism 3 retreats, and the winding roller 7 drives the paper roll 100 to rotate to perform the automatic winding task of the PET film. When the PET film layer of the specified number of turns is wound on the paper roll 100, the lifting and receiving mechanism 6 rises and carries the rolled material roll of the PET film, and then the front and rear transverse mechanism 5 drives the winding roller 7 to retreat, and the lifting and receiving mechanism 6 carries the rolled material roll of the PET film down to carry out the unloading work. Compared with the prior art, the utility model better realizes the automatic loading and loading of paper rolls, and can automatically unload after the winding is completed, so it has more automation performance and higher work efficiency. At the same time, the various mechanisms of the utility model are reasonably arranged and compact in structure, which can effectively save equipment space.
[0025] In order to facilitate the introduction of the PET film and to wind the PET film onto the paper roll 100 , in this embodiment, an auxiliary winding roller group 21 is provided on the front end plate 2 .
[0026] See also Figure 2 In this embodiment, the paper tube picking and placing mechanism 3 includes a left-right lateral movement mechanism 30 and a paper tube picking and placing clamp 31 provided at the moving end of the left-right lateral movement mechanism 30. The left-right lateral movement mechanism 30 is preferably a linear motion module, and the moving end of the left-right lateral movement mechanism 30 has a lateral movement arm 32, and the paper tube picking and placing clamp 31 is provided at the front end of the lateral movement arm 32.
[0027] As a preferred embodiment, the paper tube pushing mechanism 4 includes a pushing motion mechanism 40 and a pushing plate 41 provided at a moving end of the pushing motion mechanism 40 , and the moving direction of the pushing motion mechanism 40 is perpendicular to the moving direction of the left and right transverse movement mechanism 30 .
[0028] See also Figure 1 In the above structure, the pushing motion mechanism 40 is preferably a linear motion module extending forward and backward. In order to better abut with the paper tube 100, in this embodiment, the pushing plate 41 is a cross pushing plate.
[0029] In this embodiment, two parallel slide bars 42 are fixed on the frame 1, and the vertical position of the slide bars 42 is higher than the material pushing mechanism 40. The paper tube 100 is carried on the two slide bars 42, and the paper tube 100 can slide relative to the two slide bars 42. Among them, the vertical position of the two slide bars 42 is slightly higher than the material pushing mechanism 40. When the paper tube 100 is placed on the two slide bars 42 and when the push plate 41 pushes the paper tube 100, position interference between the paper tube 100 and the material pushing mechanism 40 can be avoided, thereby ensuring that the paper tube 100 is pushed forward straightly and stably.

The winding roller shaft 7 is arranged on the front-to-back traverse platform 50, and the front-to-back traverse platform 50 is provided with a motor assembly 52 for driving the winding roller shaft 7. The front-to-back traverse platform 50 is slidably matched with the frame 1 through a slide rail and a slider, and the linear cylinder 51 is used to push and pull the front-to-back traverse platform 50, thereby realizing the front-to-back movement function. The motor assembly 52 is preferably a servo motor, which can reliably drive the winding roller shaft 7 to operate.
