In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0037] Please refer to Figures 1-4 The present application provides a film roll forming mechanism, which comprises a rack 10, a first roller seat 20, a first roller 30, a second roller seat 40, a second roller 50 and an adjusting device 60.

[0038] Please refer to Figure 1 And Figure 2 The rack 10 is used to provide a mounting reference. The first roller seat 20, the second roller seat 40 and the adjusting device 60 are all mounted on the rack 10.

[0039] The second roller seat 40 can move away from or move close to the first roller seat 20. That is, the interval between the first roller seat 20 and the second roller seat 40 can be adjusted.

[0040] The first roller 30 is rotatably arranged on the first roller seat 20. The second roller 50 is rotatably arranged on the second roller seat 40. The second roller 50 and the first roller 30 have a gap for producing a film therebetween. It can be understood that by moving the second roller seat 40, the second roller 50 follows the movement, thereby adjusting the gap between the second roller 50 and the first roller 30, that is, adjusting the thickness of the film.

[0041] The adjusting device 60 is used to adjust the wedge block assembly 61 and the adjusting motor 62. The wedge block assembly 61 is located on the side of the second roller seat 40 away from the first roller seat 20, and the wedge block assembly 61 is arranged between the second roller seat 40 and the rack 10. The adjusting motor 62 can act on the wedge block assembly 61 to adjust the size of the wedge block assembly 61 between the second roller seat 40 and the rack 10.

[0042] It can be understood that the wedge assembly 61 is located on the side of the second roller seat 40 away from the first roller seat 20, and the wedge assembly 61 is arranged between the second roller seat 40 and the frame 10. By adjusting the motor 62 acting on the wedge assembly 61, the size of the wedge assembly 61 between the second roller seat 40 and the frame 10 is adjusted, at this time the second roller seat 40 moves relative to the frame 10, so that the size between the first roller seat 20 and the second roller seat 40 is adjusted, and the gap between the first roller 30 in the first roller seat 20 and the second roller 50 in the second roller seat 40 follows the adjustment, thereby realizing the adjustment of the film thickness. And because the wedge assembly 61 has a leverage effect, the driving force requirement is greatly reduced, so that the adjusting motor 62 can meet the demand, thereby making the structure more compact and reducing the floor area. In addition, the first roller 30 and the second roller 50 are extruded by the film during the extrusion process. The above-mentioned reaction force is applied to the wedge assembly 61, at this time the wedge assembly 61 can be frictionally engaged and rigidly supported to meet the required large pressure process production requirements.

[0043] It can be understood that the adjusting motor 62 can act on the wedge assembly 61 to reduce the size of the wedge assembly 61 between the second roller seat 40 and the frame 10, at this time the second roller seat 40 can continue to remain stationary due to friction.

[0044] For this purpose, in some embodiments, the film roller forming mechanism includes a return elastic member 70 connected between the second roller seat 40 and the frame 10, for making the second roller seat 40 have a tendency to move away from the first roller seat 20. That is, when the size of the wedge assembly 61 between the second roller seat 40 and the frame 10 is reduced, the return elastic member 70 provides elastic force to make the second roller seat 40 move away from the first roller seat 20, at this time the size of the gap between the first roller 30 and the second roller 50 changes. When the size of the wedge assembly 61 between the second roller seat 40 and the frame 10 increases, the return elastic member 70 is in the process of elastic potential.

[0045] The specific type of the return elastic member 70 is not limited, for example, it can be a tension spring. The number of tension springs can be one or more.

[0046] In some embodiments, the frame 10 includes a first frame body 11, a second frame body 12, and a connecting bracket 13 connecting the first frame body 11 and the second frame body 12, and the first frame body 11 and the second frame body 12 both surround the mounting groove 10a.

[0047] The first roller 30 has a first roller seat 20 at each end, and the second roller 50 has a second roller seat 40 at each end. The first roller seat 20 at one end of the first roller 30 and the second roller seat 40 at one end of the second roller 50 are arranged in the mounting groove 10a of the first frame body 11, and the first roller seat 20 at the other end of the first roller 30 and the second roller seat 40 at the other end of the second roller 50 are arranged in the mounting groove 10a of the second frame body 12.

[0048] It can be understood that the thickness of the film is directly affected by the parallelism between the first roller 30 and the second roller 50. By arranging the two first roller seats 20 and the two second roller seats 40 in the mounting groove 10a respectively, the first roller 30 and the second roller 50 have a common mounting reference, thereby improving the assembly accuracy to ensure the parallelism.

[0049] Please refer to Figure 2 and Figure 4 , in order to further improve the parallelism of the first roller 30 and the second roller 50. In some embodiments, the mounting groove 10a of the first frame body 11 and the mounting groove 10a of the second frame body 12 each have a first side wall 111 and a second side wall 112 opposite to each other. That is, the mounting groove 10a of the first frame body 11 has a first side wall 111 and a second side wall 112 opposite to each other, and the mounting groove 10a of the second frame body 12 also has a first side wall 111 and a second side wall 112 opposite to each other.

[0050] The first side wall 111 is provided with a top rod, which can be held on one side of the first roller seat 20 and the second roller seat 40, so that the first roller seat 20 and the second roller seat 40 abut against the second side wall 112. It can be understood that the top rod is held on one side of the first roller seat 20 and the second roller seat 40, so that the first roller seat 20 abuts against the second side wall 112, and the second roller seat 40 also abuts against the second side wall 112. At this time, the second side wall 112 serves as a positioning surface of the first roller seat 20 and the second roller seat 40, and the gap is eliminated by the holding of the top rod.

[0051] It can be understood that the surface of the second side wall 112 in contact with the first roller seat 20 and the second roller seat 40 is a plane. The above plane can obtain higher flatness and roughness through processing, thereby ensuring the positioning accuracy of the first roller seat 20 and the second roller seat 40.

[0052] The top rod can be connected to the first side wall 111 through a threaded structure. The reaction force during the holding process can be transmitted to the first side wall 111 through the thread, thereby avoiding the reverse effect on the holding effect.

[0053] The number of top rods is not limited and can be one or more. In some embodiments, the number of top rods is multiple, and part of the top rods hold the first roller seat 20 and the remaining top rods hold the second roller seat 40.

[0054] Referring to Figure 2 and Figure 4 , in order to reduce the resistance during the movement of the second roller seat 40. In some embodiments, the rack 10 comprises a sliding plate 81, which is located between the first side wall 111 and the second roller seat 40, and one side of the sliding plate 81 in the thickness direction abuts against the top rod, and the other side of the sliding plate 81 in the thickness direction abuts against the second roller seat 40. Among them, the other side of the sliding plate 81 in the thickness direction is provided with an oil guide groove.

[0055] It can be understood that by setting the oil guide groove, the friction between the other side of the sliding plate 81 in the thickness direction and the second roller seat 40 is reduced, thereby reducing the resistance of moving the second roller seat 40.

[0056] Among them, the oil guide groove is an open groove, which has an overall 8-shaped structure and has two triangularly arranged grooves in communication.

[0057] In order to further limit the positions of the first roller seat 20 and the second roller seat 40 in the axial direction of the first roller 30. In some embodiments, the rack 10 comprises a baffle plate 82, which is detachably mounted on the side of the first frame body 11 away from the second frame body and the side of the second frame body away from the first frame body. After the baffle plate 82 is installed, the baffle plate 82 is distributed at both ends of the first roller 30 and both ends of the second roller 50. Here, the axial direction of the first roller 30 is also the axial direction of the second roller 50.

[0058] In the plane perpendicular to the axial direction of the first roller 30, the projection of the first roller seat 20, the projection of the second roller seat 40 and the projection of the baffle plate 82 partially overlap. In this way, the baffle plate 82 can hinder the movement of the first roller seat 20 and the second roller seat 40 in the axial direction of the first roller 30, thereby limiting the axial positions of the first roller 30 and the second roller 50.

[0059] It can be understood that when the baffle plate 82 abuts against the second roller seat 40, there will be a frictional resistance between the baffle plate 82 and the second roller seat 40. In some embodiments, a guide bearing is arranged between the baffle plate 82 and the second roller seat 40, which can guide the sliding of the second roller seat 40.

[0060] The specific structure of the adjusting device 60 is not limited, as long as it can adjust the size of the wedge block assembly 61 between the second roller seat 40 and the rack 10 through the adjusting motor 62.

[0061] Referring to Figure 3 In some embodiments, the adjusting device 60 comprises a speed reducer 63 and a lead screw assembly 64, the adjusting motor 62 is drivingly connected with the speed reducer 63, the speed reducer is drivingly connected with the lead screw assembly 64, and the adjusting motor 62 is perpendicular to the lead screw assembly 64.

[0062] The speed reducer 63 can increase the output torque of the adjusting motor 62, thereby reducing the size and output power of the adjusting motor 62, and reducing the cost. By arranging the adjusting motor 62 perpendicularly to the screw assembly 64, the overall size of the adjusting motor 62 and the screw assembly 64 in the axial direction of the screw assembly 64 can be reduced, thereby facilitating installation.

[0063] It can be understood that the first roller 30 can be fixed relative to the frame 10. Figure 2 The wedge assembly 61 includes two wedges 611 that cooperate with each other, one of which is connected to the screw assembly 64 and is driven to move by the screw assembly 64 to adjust the size of the two wedges 611 as a whole between the second roller seat 40 and the frame 10.

[0064] The wedge 611 has a wedge surface, and the wedge surfaces of the two wedges 611 are opposite to each other. The screw assembly 64 includes a screw and a screw nut, one wedge 611 is connected to the screw nut, the screw rotates to drive the screw nut and the wedge 611 to move relative to the other wedge 611, at this time the wedge surfaces of the two wedges 611 slide relative to each other, thereby adjusting the size of the two wedges 611 as a whole between the second roller seat 40 and the frame 10.

[0065] It can be understood that the first roller 30 can be fixed relative to the frame 10.

[0066] It can be understood that the first roller 30 can be fixed relative to the frame 10. Figure 1 In some embodiments, the film roller forming mechanism includes a roller driving device 90, the roller driving device 90 includes a roller motor 91 and a gear 92, the roller motor 91 is drivingly connected to the first roller 30, and the gear 92 is arranged on the first roller 30 and the second roller 50. The gear 92 of the first roller 30 and the gear 92 of the second roller 50 are meshed with each other and have the same number of teeth. It should be noted that when the second roller moves, the spacing between the two gears 92 changes slightly, and the above change does not affect the meshing of the gears.

[0067] It can be understood that the roller motor 91 drives the first roller 30 to rotate, and the gear 92 arranged on the first roller 30 rotates, thereby driving the gear 92 arranged on the second roller 50 and the second roller 50 to rotate. Since the gear 92 of the first roller 30 and the gear 92 of the second roller 50 have the same number of teeth, the first roller 30 and the second roller 50 rotate at the same speed.

[0068] The roller motor 91 and the first roller 30 are connected through a shaft coupling 93. The shaft coupling 93 can compensate for the axial, radial and angular deviations between the first roller 30 and the main shaft of the roller motor 91 due to manufacturing, installation, etc., and has the ability to absorb vibration and impact, thereby reducing the degree of vibration of the roller motor 91 transmitted to the first roller 30, and reducing the impact on film production.

[0069] The utility model embodiment has been explained in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiment, still can make various changes in the knowledge range of the ordinary skill of the art person who possesses under the premise of not departing from the utility model tenet. Besides, the embodiment and the feature in the embodiment of the utility model can be combined mutually under the condition of not conflicting.
