Description

Technical Field

[0001] The utility model relates to the field of PC composite film production equipment, in particular to a PC composite film edge material rolling-up mechanism. Background Art

[0002] PC / PMMA composite film is made by co-extrusion of PC and PMMA, which combines the high impact strength and bending resistance of PC material with the good hardness and wear resistance of PMMA material, so as to improve the overall toughness of the material. PC / PMMA composite film is high-definition and transparent, with high gloss and strong printability. After texture production, it can obtain a good streamer and colorful glass effect; after hardening, the drop resistance is greatly improved, and there is no signal shielding, which can perfectly replace glass for mobile phone back cover and touch window.

[0003] In the production process of PC / PMMA composite film, in order to ensure the quality of the produced film, the edge material needs to be cut off during the winding process. For example, the utility model patent with publication number CN214520637U provides a trimming and winding mechanism, which includes a bracket, on which a guide roller for guiding the film is installed, one side of the bracket is used for trimming the edge of the film and is provided with a trimming mechanism, and a winding mechanism corresponding to the trimming mechanism is provided; the winding mechanism includes: a bottom plate fixed on the bracket, on which a slide rail is provided; a sliding seat that slides along the slide rail, on which a winding roller for winding waste material and a driving motor for driving the winding roller are installed. During the process of film roll forming and discharging, the edge of the film is trimmed to control the width of the film roll, and the trimmed waste edge is automatically collected by the winding mechanism to improve production efficiency.

[0004] The utility model patent with publication number CN 215848548 U discloses a composite film trimming device, including a bracket, on which a guide roller for guiding a film is installed, and a trimming mechanism is provided on one side of the bracket, and the trimming mechanism includes: a base fixed to the bracket, on which a guide rail is provided; and a cutter seat slidingly matched along the guide rail is provided, and a cutter is installed on the cutter seat. The edge of the film is trimmed during the discharge process of the roll film, and the width of the roll film can also be controlled at the same time, without the need for trimming treatment later, thereby improving production efficiency.

[0005] The edge trimming and winding mechanism in the above-mentioned prior art is directly integrated into the film winding device, and the waste edge processing is completed directly during winding to realize the control of the film roll width. However, it is more difficult to remove the edge material roll, and it is necessary to observe the thickness of the edge material roll from time to time and disassemble it in time to avoid the edge material roll being too large and affecting normal production. Utility Model Content

[0006] In view of the problems existing in the prior art, the utility model provides a PC composite film edge material winding mechanism, which can be independently installed on different trimming equipment, and uses an angle-adjustable guide column and a tension wheel to control the winding tension of the edge material on the winding disk.

[0007] A PC composite film edge material winding mechanism comprises a base, on which is provided:

[0008] Angle-adjustable guide column with a guide groove in the middle for the edge material to pass through;

[0009] A tension wheel is mounted on a movable swing arm;

[0010] The winding plate is driven by a motor installed on the base to wind up the edge material;

[0011] The limiting rod is used to control the swing amplitude of the swing arm.

[0012] In the present application, the edge material to be wound up passes through the guide groove in the guide column, bypasses the tension wheel, and is wound around the winding material disk; the tension of the edge material is adjusted simultaneously by using the angle-adjustable guide column and the tension wheel, and the limit rod is used to control the swing angle of the swing arm.

[0013] Preferably, the middle portion of the swing arm is connected to a rotating shaft passing through the base, a fan-shaped sensing portion is provided at the end of the rotating shaft, and a sensor cooperating with the sensing portion is provided on the base.

[0014] As the thickness of the edge material on the winding disk continues to increase, the tension wheel gradually moves upward, driving the fan-shaped sensing part at the end of the rotating shaft to move. When the fan-shaped sensing part completes the escape from the touch range of the sensor, the sensor sends a signal to control the guide column to adjust the angle.

[0015] Further preferably, the sensing portion includes a first sensing portion and a second sensing portion which are arranged at a right angle, and the sensor includes a first sensor and a second sensor which cooperate with the first sensing portion and the second sensing portion respectively.

[0016] The utility model adopts two fan-shaped first sensing parts and second sensing parts, and is equipped with a first sensor and a second sensor; the first sensing part cooperates with the first sensor to send a signal to control the angle of the guide column and adjust the tension of the edge material; the second sensing part cooperates with the second sensor to send a signal to control the winding material tray to stop winding the material. The guide column is driven by an adjustment motor installed on the base, and the adjustment motor controls the rotation of the guide column according to the signal of the sensor. The motor stops driving the winding material tray to rotate according to the signals of the first sensor and the second sensor.

[0017] To facilitate installation of the tension wheel, preferably, the swing arm includes two parallel swing brackets, and the tension wheel is installed at one end between the two swing brackets.

[0018] The limit rod is used to control the maximum swing amplitude of the swing arm to avoid collision between the tension wheel and the winding material disk. Preferably, the limit rod is a screw rod, and the end thread is engaged in the positioning hole on the base; further, the positioning holes are multiple and evenly spaced and at different heights, or the width of the swing arm can be adjusted as needed to adapt to winding material disks of different diameters.

[0019] The utility model has the advantages of simple structure, convenient operation, and can be independently installed on different trimming equipments. The winding tension of the trimming material on the winding and receiving tray is controlled by the cooperation of the guide column with adjustable angle and the tension wheel.
