[0002] Pre-coating refers to the process of pre-gluing and rewinding plastic film before laminating it with paper printed products. The pre-coating factory first applies glue on the film according to the specifications and format, then rewinds it for the user to choose, and then laminates it with the printed product. Laminating, also known as film pasting, is the processing technology of coating plastic film with adhesive, and bonding it with paper printed products after heating and pressurizing to form a paper-plastic integrated product.

[0003] In order to ensure the quality of the pre-coated film during its production, the thickness of the pre-coated film needs to be measured. However, during the transportation of the pre-coated film, the pre-coated film is prone to become loose and wrinkled, resulting in errors in the measurement of the pre-coated film. Therefore, a thickness gauge for pre-coated film is provided. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-2 The utility model provides a technical solution: a thickness gauge for pre-coated film, comprising a frame 1, on which a pre-coated film feeding roller 2, an adjusting roller mechanism, a thickness measuring mechanism and a pre-coated film receiving roller 5 are sequentially arranged; the pre-coated film feeding roller 2 and the pre-coated film receiving roller 5 synchronously and uniformly feed and discharge the pre-coated film, the pre-coated film feeding roller 2 is used for feeding the pre-coated film, the adjusting roller mechanism is used for adjusting the tension and wrinkles of the pre-coated film, the thickness measuring mechanism is used for measuring the thickness of the pre-coated film, and the pre-coated film receiving roller 5 is used for winding the measured pre-coated film, thereby completing the accurate measurement of the pre-coated film.

[0018] Specifically, the thickness measuring mechanism includes a mounting seat 4-1 arranged on the frame 1, the mounting seat 4-1 is arranged as an annular mounting seat, a laser thickness gauge 4-2 is arranged on the mounting seat 4-1, and a plurality of light source probes 4-3 and receiving probes 4-4 are respectively arranged on the mounting seat 4-1 and located on the upper and lower sides of the pre-coated film, the light source probes 4-3 and the receiving probes 4-4 are both electrically connected to the laser thickness gauge 4-2, and the light source probes 4-3 cooperate with the receiving probes 4-4 to detect multiple locations of the pre-coated film, thereby improving the detection efficiency of the pre-coated film, and transmitting the detected information to the laser thickness gauge 4-2 to realize the thickness measurement of the pre-coated film;

[0019] Specifically, the adjusting roller mechanism includes a plurality of fixed adjusting rollers 3-1 and a plurality of lifting adjusting rollers 3-2. The plurality of lifting adjusting rollers 3-2 are staggered with the plurality of fixed adjusting rollers 3-1. The plurality of fixed adjusting rollers 3-1 are arranged on a frame 1. The frame 1 is provided with a driving assembly for driving the plurality of lifting adjusting rollers 3-2 to rise and fall. During the conveying process of the pre-coated film, the lifting adjusting rollers 3-2 are driven to rise by the driving assembly, so that the lifting adjusting rollers 3-2 and the fixed adjusting rollers 3-1 are moved away from each other, so as to adjust the tension of the pre-coated film during the conveying process, so as to avoid the loosening of the pre-coated film and cause errors in the measurement of the pre-coated film.

[0020] Specifically, the driving assembly includes an electric cylinder 3-3 arranged on the frame 1, and a lifting seat 3-4 is provided at the output end of the electric cylinder 3-3. Several lifting and adjusting rollers 3-2 are jointly arranged on the lifting seat 3-4. A pressure sensor 3-5 is provided on the electric cylinder 3-3. The lifting seat 3-4 and several lifting and adjusting rollers 3-2 are driven to rise by the electric cylinder 3-3, so that the lifting and adjusting rollers 3-2 and the fixed adjusting rollers 3-1 are moved away from each other to adjust the tension of the pre-coated film during the conveying process. The pressure sensor 3-5 cooperates with the electric cylinder 3-3 to make the lifting and adjusting rollers 3-2 provide stable supporting force for the pre-coated film, thereby ensuring the stability of the tension during the conveying process and avoiding the loosening of the pre-coated film and causing errors in the measurement of the pre-coated film.

[0021] Specifically, the fixed adjustment roller 3-1 and the lifting adjustment roller 3-2 are both configured as centrally symmetrical bidirectional inclined groove flexible flattening rollers, which effectively avoid the positional displacement of the pre-coated film during the flattening process, and the inclined grooves on the fixed adjustment roller 3-1 and the lifting adjustment roller 3-2 are in opposite directions, thereby ensuring the flattening effect of the wrinkles on the pre-coated film. By flattening the wrinkles on the pre-coated film multiple times during the conveying process, errors in the measurement of the pre-coated film caused by wrinkles on the pre-coated film can be avoided.

[0022] Specifically, a pair of conveying rollers 6 are symmetrically provided at both ends of the mounting seat 4-1, and the gap between the two conveying rollers on the pair of conveying rollers 6 is adjusted to the maximum spacing through which the pre-coated film can pass, thereby effectively avoiding the oscillation of the pre-coated film due to the equipment body during the conveying process, and ensuring the stability of the pre-coated film when the pre-coated film enters the thickness measuring mechanism.

[0023] Working principle: During the use of the utility model, the thickness measuring mechanism is first started. During the conveying process of the pre-coated film, the electric cylinder 3-3 is started to drive the lifting seat 3-4 and several lifting adjustment rollers 3-2 to rise, so that the lifting adjustment rollers 3-2 and the fixed adjustment rollers 3-1 are moved away from each other to adjust the tension. During the rotation of the fixed adjustment rollers 3-1 and the lifting adjustment rollers 3-2, the flexible inclined groove flattens the wrinkles of the pre-coated film, thereby ensuring the accuracy of the pre-coated film thickness measurement.
