[0024] In the following description, a lot of specific details are set forth in order to fully understand the utility model, but the utility model can also be implemented in other ways different from the description, and those skilled in the art can make similar generalization without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0025] Secondly, "one embodiment" or "embodiment" referred to here means that specific features, structures or characteristics can be included in at least one implementation of the utility model. "In one embodiment" does not mean the same embodiment in different places in this specification, and is not an embodiment that is independent or alternative to other embodiments.

[0026] EMBODIMENT

[0027] REFERENCE Figs. 1-4 For the embodiment of the utility model, the embodiment provides a film winding equipment, which comprises,

[0028] The bearing mechanism 100 comprises a bearing seat 101, an axle rod 102 rotatably installed on the inner side of the bearing seat 101, a winding roller 103 fixedly installed on the outer surface of the axle rod 102 and a bearing seat 104 fixedly installed on the end of the axle rod 102.

[0029] The pushing mechanism 200 comprises a fixing base 201 arranged outside the bearing seat 101, a cylinder 202 fixedly installed outside the fixing base 201, and a machine shell 203 fixedly installed outside the cylinder 202.

[0030] The sensing mechanism 300 is used in cooperation with the pushing mechanism 200.

[0031] During the winding process, the compression roller 107 can uniformly apply pressure to the film, and the diaphragm is evenly wound on the winding roller 103, avoiding problems such as wrinkles and deviation, effectively solving the problem that the uneven winding of the diaphragm affects the coating effect of the next process and the quality of the finished product.

[0032] Specifically, the bearing mechanism 100 further comprises a swing assembly 105 arranged at the bottom of the bearing seat 101, a limiting assembly 106 arranged in the inner cavity of the bearing seat 101, and a compression roller 107 fixedly installed outside the limiting assembly 106.

[0033] Further, the pushing mechanism 200 further comprises an air inlet pipe head 204 fixedly installed at the top of the machine shell 203, a first piston rod 205 movably sleeved in the inner cavity of the cylinder 202, and a nut 206 fixedly installed outside the machine shell 203.

[0034] The cylinder 202 is connected with the second piston rod 302 of the linear displacement sensor 301, and the linear displacement sensor 301 is connected with the programmable logic controller 304a. At this time, the programmable logic controller 304a records the position data. During production, the first piston rod 205 of the cylinder 202 is connected with the swing arm 105a of the compression roller 107. When the compression roller 107 contacts with the film, with the increase of the diameter of the winding film, the swing arm 105a is affected by the pressure and then retreats, driving the first piston rod 205 to move, and then the second piston rod 302 connected with the nut 206 also moves correspondingly.

[0035] Preferably, the sensing mechanism 300 comprises a linear displacement sensor 301 arranged outside the pushing mechanism 200, a second piston rod 302 movably sleeved in the inner cavity of the linear displacement sensor 301, a spring 303 sleeved and installed on the outer surface of the second piston rod 302, and a control assembly 304 arranged at one end of the second piston rod 302. The other end of the second piston rod 302 is threadedly connected with the nut 206.

[0036] The linear displacement sensor 301 can accurately detect the position change of the second piston rod 302 and feed the value back to the programmable logic controller 304a. The programmable logic controller 304a controls the movement of the winding wall motor according to the received position data size, ensures the stable stress between the film and the pressure roller 107, and the pressure feedback mechanism based on the linear displacement sensor 301 and the programmable logic controller 304a can timely and efficiently feed the pressure of the pressure roller 107 to the programmable logic controller 304a. Compared with the existing way of using the light control motor to advance the position, the influence of external factors is small, and the stability of the film production process is greatly improved.

[0037] Further, the control assembly 304 includes a programmable logic controller 304a fixedly installed at the end of the second piston rod 302, a support frame 304b fixedly installed outside the programmable logic controller 304a, and a sensing element 304c fixedly installed outside the support frame 304b.

[0038] Further, the swing assembly 105 includes a swing arm 105a fixedly installed at the bottom of the pressure roller 107, a rectangular groove 105b opened in the inner cavity of the swing arm 105a, a connecting block 105c fixedly installed in the inner cavity of the rectangular groove 105b, a fixed block 105d fixedly installed outside the connecting block 105c, and a positioning block 105e fixedly installed outside the connecting block 105c. The positioning block 105e is fixedly connected with the end of the first piston rod 205.

[0039] The swing assembly 105 can make the pressure roller 107 swing flexibly through the cooperation of the swing arm 105a, the rectangular groove 105b, the connecting block 105c, the fixed block 105d and the positioning block 105e. The positioning block 105e is fixedly connected with the end of the first piston rod 205, ensuring that the swing of the pressure roller 107 is closely matched with the action of the pushing mechanism 200.

[0040] Further, the limiting assembly 106 includes a limiting groove 106a opened in the inner cavity of the bearing seat 101, a limiting sliding block 106b movably installed in the inner cavity of the limiting groove 106a, and a limiting guide rail 106c fixedly installed in the inner cavity of the limiting groove 106a. The bottom of the limiting sliding block 106b is movably clamped on the top of the limiting guide rail 106c, and the limiting sliding block 106b is rotatably connected with the end of the pressure roller 107.

[0041] The limiting assembly 106 uses the limiting groove 106a, the limiting sliding block 106b and the limiting guide rail 106c to accurately guide and limit the movement of the pressure roller 107, ensuring that the pressure roller 107 always maintains a stable movement trajectory during the working process.

[0042] In use, before production, the cylinder 202 of the pushing mechanism 200 is filled with air through the air inlet pipe head 204, the cylinder 202 retreats to drive the second piston rod 302 of the sensing mechanism 300 to retreat, and the programmable logic controller 304a records the position data of the linear displacement sensor 301 at this time;

[0043] During production, the pressure roller 107 is in contact with the film, and as the diameter of the rolled film increases, the swing arm 105a of the swing assembly 105 retreats under the influence of pressure, the first piston rod 205 is driven to move through the positioning block 105e, and then the second piston rod 302 connected with the nut 206 is moved, the linear displacement sensor 301 feeds back the detected value to the programmable logic controller 304a, and the programmable logic controller 304a controls the movement of the winding wall motor according to the size of the position data, so as to ensure that the force between the film and the pressure roller 107 is stable, and the film is evenly wound on the winding roller 103 of the bearing mechanism 100.

[0044] In summary, the winding of the film is realized through the winding roller 103 in the bearing mechanism 100, the swing arm 105a and the positioning block 105e in the swing assembly 105 cooperate with the first piston rod 205 of the pushing mechanism 200, so that the pressure roller 107 can swing flexibly and apply pressure uniformly, the limiting groove 106a, the limiting sliding block 106b and the limiting guide rail 106c of the limiting assembly 106 ensure the stable movement of the pressure roller 107, guarantee the smooth winding of the diaphragm and improve the quality of the finished product; at the same time, the linear displacement sensor 301 and the second piston rod 302 of the sensing mechanism 300 cooperate with the programmable logic controller 304a in the control assembly 304, which can efficiently feedback the pressure of the pressure roller 107 to the programmable logic controller 304a in time, and the influence of external factors is small, which greatly improves the stability of the film production process.
