Detailed Description
The invention is described in detail below with reference to the drawings and the detailed description.
As shown in FIG. 1, the automatic film collecting device of the polaroid die punch comprises a bracket, a polarized light belt traction roller, a middle rotating roller, a polaroid receiving table and a waste material collecting roller.
The polarized light belt traction roller comprises an upper traction roller and a lower traction roller, and two ends of the upper traction roller and the lower traction roller are respectively movably arranged in the bracket. The bearing blocks at two ends of the upper traction roller can move up and down in the fixing groove of the support, a pressing spring is arranged in the fixing groove, the lower end of the pressing spring is connected with the bearing block, the upper end of the pressing spring is movably connected with the bottom end of the screw rod, the screw rod is in threaded connection with the support at the top of the fixing groove, and the pressing pressure of the spring on the bearing blocks can be adjusted by rotating the screw rod. The upper traction roller and the lower traction roller are mutually parallel and elastically abutted. One end of the lower traction roller is connected with a traction motor and is driven to rotate by the traction motor. The polarized light belt punched by the cutting die is pressed and pulled when passing between the upper traction roller and the lower traction roller, and the moving speed of the polarized light belt is controlled.
The transfer roller is arranged between the lower traction roller and the polaroid receiving table, and the roller surface at the top of the transfer roller is at the same height as the roller surface at the top of the lower traction roller, so that the polarizing belt horizontally moves between the polarizing belt and the transfer roller support, and the polaroid is prevented from being separated from the polarizing belt in advance. The two ends of the transfer roller are rotatably connected to the bracket, and the transfer roller can rotate freely. A waste material downward rotating gap is arranged between the transfer roller and the feeding port of the polaroid receiving table. After the polarizer is separated from the polarizing belt, the remaining polarizing belt becomes a waste material. The polarized light belt is forced to draw, bend and rotate because the polarized light belt passes through the transfer roller and then suddenly enters the waste material downward-rotating gap, and the front end of the polaroid is tilted and separated from the polarized light belt due to self elasticity.
A polarizer receiving plate is arranged on the feeding port of the polarizer receiving table. The width of the gap between the polaroid receiving plate and the intermediate rotating roller is adjustable, so that the gap between the polaroid receiving plate and the intermediate rotating roller is minimized, the front end of the polaroid can be extended onto the polaroid receiving plate by slightly tilting, the polaroid can be prevented from entering the waste material down-rotating gap to the greatest extent, and the polaroid can be stripped from the polarizing band more effectively. The upper plate surface of the polaroid receiving plate is lower than the upper end of the transfer roller and is positioned on one side of the transfer roller, so that a larger ejection space and ejection time are reserved above the polaroid receiving plate for the polaroid, and the front end of the polaroid is tilted more effectively. The polarizer stripped by the polarizer receiving plate is automatically pushed onto the polarizer receiving table.
The waste material roll-up roller sets up in the support bottom, and waste material roll-up roller one end is connected with the roll-up motor and rotates through roll-up motor drive. The waste material winding roller collects waste materials through rotating winding, and pulls the polarized light belt behind the polarizer pulling roller to enable the polarized light sheet to be actively peeled off on the polarizer receiving plate.
As shown in FIG. 1, the device further comprises a pressing roller, wherein the pressing roller is arranged above the transfer roller, two ends of the pressing roller are fixedly connected with the support, and a polarized light band pass gap is reserved between the pressing roller and the transfer roller. The pressing roller is used for pressing the polarized light belt above the transfer roller, so that the upward tilting of the polarized light belt above the transfer roller is reduced, the tilting separation elasticity of the front end of the polaroid during downward rotation is increased, and the polaroid is more effectively separated from the polarized light belt.
As shown in FIG. 1, the polarizer receiving platform further comprises a transparent cover plate, wherein the transparent cover plate covers the upper part of the feed inlet of the polarizer receiving platform, the upper end of the transparent cover plate is connected with the pressing roller, and the lower end of the transparent cover plate is lapped in the polarizer receiving platform. The transparent cover plate can be turned upwards around the pressing roller to be opened. The transparent cover plate is used for covering the polaroid in the stripping process, so that the polaroid can be prevented from bouncing and scattering in the stripping process, the stripped polaroids can be concentrated together, and the subsequent arrangement is convenient. Meanwhile, due to the transparency of the transparent cover plate, workers can conveniently observe the stripping effect and the accumulation quantity of the polaroids below the transparent cover plate, and faults can be conveniently discharged in time and the polaroids can be conveniently cleaned.
As shown in fig. 1, the transparent cover plate is a flexible cover plate or the upper end of the transparent cover plate is flexibly connected with the pressure blocking roller through an adhesive tape. The flexible cover plate has better elasticity, is convenient for the transparent cover plate to turn up and open, simultaneously provides better flexible buffering for the polaroid in the stripping process, and further reduces the bouncing of the polaroid. The transparent cover plate is connected to the pressing roller through the adhesive tape, so that the transparent cover plate can be integrally turned over by utilizing the flexibility of the adhesive tape, and the turning-over and opening degree of the transparent cover plate is larger.
As shown in fig. 1, the upper table surface of the polarizer receiving table is an inclined surface, and the other end position of the upper table surface of the polarizer, which is far away from the feed inlet, is lower, for example, is inclined downwards by 25 degrees, so that the polarizer can automatically move to the other end bottoming position of the polarizer receiving table, the situation that the polarizer is stacked too high at one end of the feed inlet and the polarizer is turned over to change the front and back surfaces is avoided.
As shown in fig. 1, the upper plate surface of the polarizer receiving plate is white. Because the polaroid is transparent gray or transparent brown, the observation is not easy, and the white background color is arranged on the polaroid receiving plate, the color of the polaroid can be highlighted, and then the segment of the sheet can be observed conveniently, and the number and the stacking thickness of the segment of the sheet can be observed conveniently.
As shown in fig. 1, the scrap collecting roller side is provided with scrap slots. The waste material slot is used for inserting the waste material head, so that the waste material rolling roller can rapidly start rolling the polarized light belt waste material, and the waste material rolling device is more convenient and efficient.
As shown in fig. 1, the scrap winding roller is disposed below the transfer roller and near one side of the polarized light belt traction roller, so that the downward bending angle of the polarized light belt is greater than 90 °, for example 110 °, after passing through the transfer roller, the bending angle of the polarized light belt is greater and the time for maintaining the greater bending angle is longer, thereby further promoting the polarizer after passing through the transfer roller to tilt up and separate from the polarized light belt.
As shown in fig. 1, the winding motor is an adaptive motor. When the self-adaptive motor works, the magnitude of the generated electromagnetic torque can be automatically adjusted within a certain range to adapt to the change of the load. The self-adaptive motor can keep the tension of the polarized light closing belt, avoid pulling the polarized light belt out, ensure that the polarized light belt is tightly attached to the transfer roller, and ensure the bending angle of the polarized light belt when passing through the transfer roller, thereby further promoting the polarizer after passing through the transfer roller to tilt up and separate from the polarized light belt.
As shown in fig. 1, the utility model also comprises a polarized light belt limiting wheel, the polarized light belt limiting wheel is arranged before the polarized light belt inlet of the polarized light belt traction roller, the wheel surface of the polarized light belt limiting wheel faces to the side edge of the polarized light belt, the wheel shaft of the polarized light belt limiting wheel is arranged in the movable groove at the tail end of the cutting table, the polarized light belt limiting wheel can move left and right in the movable groove, and the polarized light belt limiting wheel can be locked by a butterfly bolt. The polarizing belt limiting wheel comprises a left limiting wheel and a right limiting wheel, and the distance between the left limiting wheel and the right limiting wheel is adjustable. The polarizing belt limiting wheels are used for limiting the left and right positions of the polarizing belt entering between the polarizing belt traction rollers, so that the polarizing belt is prevented from being skewed, and faults are reduced.
