[0026] The present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] Referring to Figures 1 to 3 , the present utility model provides a deviation rectification system for a release film, including a controller 91, a deviation rectification sensor 92, an electric driver 93, and a deviation rectification roller 94; the deviation rectification sensor 92 is electrically connected to the controller 91, the controller 91 is electrically connected to the electric driver 94, and the electric driver 93 drives the deviation rectification roller 94 to work; the deviation rectification sensor 92 is arranged near the running track of the release film 99 and close to the deviation rectification roller 94, and the deviation rectification roller 94 is arranged on the running track of the release film, for example Figure 2Among them, the deviation rectifying roller 94 is arranged on the running track of the release film 99 just after it comes out of the oven, and the deviation rectifying sensor 92 is arranged near the running track of the release film 99 just after it comes out of the oven (not shown). The deviation rectifying sensor 92 can detect the edge position of the release film 99, read out the deviation amount between the actual position of the edge of the release film 99 and the set position of the edge of the release film 99, convert this deviation amount into a voltage signal proportional to it, and the deviation rectifying sensor 92 sends this voltage signal to the controller 91. After the controller 91 amplifies and calibrates this voltage signal, it outputs it to the electric driver 93. The electric driver 93 drives the deviation rectifying roller 94 to perform a correction action according to the magnitude of the input signal, and guides the release film 99 to the preset position of the release film 99. The working procedures of the controller 91, the deviation rectifying sensor 92, and the electric driver 93 are easily designed by ordinary electronic engineers and are all prior arts, so no detailed description will be given here.
[0028] See Figure 2 , from left to right are gravure positive and reverse coating, microgravure coating, unwind traction, dust removal, reserved corona, unwind unit, rewind unit, rewind traction, rewind storage, and cooling traction; the above-mentioned various parts are the 1st oven to the 8th oven; all of these are prior arts, so no detailed description will be given here.
[0029] See Figure 2 , the deviation rectifying roller 94 of the release film deviation rectifying system is generally arranged on the running track of the release film just after it comes out of the oven, and can also be arranged at the rewind unit or unwind unit of the release film, or can also be arranged at the upper winding position of the slitting device (not shown); the deviation rectifying sensor 92 is arranged near the running track of the release film just after it comes out of the oven, and the deviation rectifying sensor 92 can also be arranged near the rewind unit or the unwind unit end. The controller 91 can be set together with the main console; the electric driver 93 is arranged near the deviation rectifying roller 94 to drive the deviation rectifying roller 94 to work.
[0030] The correction action of the deviation rectifying roller 94 is that the deviation rectifying roller 94 moves along the axial direction of the deviation rectifying roller 94.
[0031] See Figure 3 and Figure 4, the deviation rectifying roller 94 is a silica gel roller, including a cylindrical main shaft 941 in the middle, and a left shaft 942 and a right shaft 943 respectively connected to both ends of the main shaft 941; multiple parallel inclined grooves 9411 are arranged on the main shaft 941, and the function of the inclined grooves 9411 is to increase resistance and have a good anti-slip effect. The main shaft 941 can be made of silica gel with a hardness of 78 and a temperature resistance of about 170 °C. The surface of the main shaft 941 is smooth, wear-resistant and temperature-resistant. Generally speaking, the deviation rectifying roller 94 of the present utility model is a roller-shaped product with a metal or other material as the core and silica gel coated on the outside and vulcanized; the materials of the left shaft 942 and the right shaft 943 are generally metal materials, such as stainless steel, and of course other materials can also be used.
[0032] See Figure 3 and Figure 4 , each inclined groove is evenly arranged on the main shaft 941, and the distance T between two adjacent inclined grooves 9411 is 40 - 70 mm.
[0033] See Figure 4 and Figure 5 , the width K of the inclined groove is 1.5 - 2.5 mm.
[0034] See Figure 4 and Figure 6 , the depth H of the inclined groove is 1.3 - 2.3 mm.
[0035] See Figures 3 to 6 , for example, the dimensions of the deviation rectifying roller 94 of the applicant are as follows: the total length L1 is 2750 mm, the length L2 of the main shaft 941 is 1750 mm, the diameter D of the main shaft 941 is 150 mm, the diameters d of the left shaft 942 and the right shaft 943 are both 35 mm, the lengths L2 of the left shaft 942 and the right shaft 943 are both 500 mm, the distance T between two adjacent inclined grooves 9411 is 55 mm, the width K of each inclined groove is 2 mm, and the depth H of each inclined groove is 1.8 mm.
[0036] See Figure 2 , the deviation rectifying roller 94 of the release film deviation rectifying system is arranged on the running track of the release film 99 just after coming out of the oven, and its purpose is to ensure that the release film 99 coming out of the oven runs in a fixed direction. The principle is: when the deviation rectifying sensor 92 under the oven outlet and the deviation rectifying roller 94 detects that the release film 99 is offset, the deviation rectifying sensor 92 transmits the offset signal to the controller 91, and then the controller 91 transmits the signal to the electric driver 93, and the electric driver 93 drives the deviation rectifying roller 94, so that the deviation rectifying roller 94 moves left and right (that is, the deviation rectifying roller 94 moves along the axis direction of the deviation rectifying roller 94). Since the deviation rectifying roller 94 is a specific type of rubber roller, it has a good anti-slip effect on the left and right movement of the release film 99, so as to achieve the purpose of deviation rectification.
