Description

Technical Field

[0001] The utility model relates to the technical field of light guide plate feeders, in particular to a light guide plate feeder capable of clamping and protecting. Background Art

[0002] A light guide plate is an optical component made of optical-grade acrylic or PC sheets with light guide points printed on them through technologies such as laser engraving, which allows light to stay on the surface of the sheet and emit light evenly. Its main function is to guide light to the desired location, improve lighting effects, and enhance visual effects. It is widely used in various occasions, such as shopping malls, offices, homes, museums, etc., to improve the lighting effects of displays and enhance display or decorative effects.

[0003] According to the transmission combination device for feeding light guide plates with announcement number CN205257480U, it includes a frame, a transmission mechanism and support and limit roller groups arranged on the frame on both sides along the feeding direction. The support and limit roller groups are connected to the frame through adjustment guide rails perpendicular to the feeding direction. The support and limit roller groups can move along the adjustment guide rails through the clamping device arranged on the frame. When in use, the support and limit roller group is used instead of the belt drive to ensure that no scratches will occur on the front and back sides of the light guide plate. However, this structure cannot fix and clamp the light guide plate during transportation, resulting in the light guide plate sliding and colliding with other objects during transportation, thereby causing scratches on the surface of the light guide plate, affecting the production quality of the light guide plate. Utility Model Content

[0004] The purpose of the present utility model is to provide a light guide plate feeder with clamping protection, so as to solve the problem proposed in the above background technology that the light guide plates are placed movably, which causes the light guide plates to slide and collide with other objects during transportation to produce scratches, thereby affecting the production quality of the light guide plates.

[0005] To achieve the above-mentioned object, the utility model provides the following technical solution: a light guide plate feeder capable of clamping and protecting, comprising a feeder body and an electric feed roller, wherein the electric feed roller is provided on the upper side of the feeder body, a mounting base is welded inside the feeder body, and a control box is installed on the upper side of the mounting base;

[0006] A mounting bracket is welded on the top of the feeder body, and an internal threaded cylinder is rotatably connected to the inside of the mounting bracket. The inside of the internal threaded cylinder is threadedly connected to the external threaded rod. One end of the external threaded rod is connected to the clamping frame. A bidirectional stepping motor is installed on the upper side of the mounting base. The output ends on both sides of the bidirectional stepping motor are connected to the rotating rod through a coupling. The outer sides of the two rotating rods and the internal threaded cylinder are connected to driving rollers, and a driving belt is provided on the outer side of the driving roller.

[0007] Preferably, a guide rod is welded to one side of the clamping frame, and the outer side of the guide rod is inserted through the through hole inside the mounting frame.

[0008] Preferably, a groove is provided inside the clamping frame, and electric push rods are installed on the mounting frame and the middle of the feeder body.

[0009] Preferably, adjacent sides of the two electric push rods are welded with mounting frames, electric feeding rollers are installed inside the two mounting frames, and the clamping frames are symmetrically arranged on the upper side of the feeder body.

[0010] Preferably, mounting grooves are provided inside the two clamping frames, and electric rods are installed in the middle of the clamping frames.

[0011] Preferably, one end of the electric rod is connected to the middle of the mounting plate, and an electric auxiliary roller is installed on the inner side of the mounting plate.

[0012] Preferably, the electrically auxiliary rollers are arranged at equal intervals inside the mounting plate, and the outer side of the mounting plate is plugged into the mounting groove on the adjacent side.

[0013] Compared with the existing technology, the beneficial effect of the utility model is that the light guide plate feeder with clamping protection can clamp and limit the two sides of the light guide plate, thereby avoiding sliding and offsetting of the light guide plate during movement, reducing the contact and collision of the light guide plate with other objects, and then effectively protecting the light guide plate to achieve the effect of limited protection. Two sets of feeding structures are provided, and the two sets of feeding results cooperate with each other to further improve the feeding efficiency of the light guide plate, and solve the problem that the light guide plate is placed movably, resulting in the light guide plate sliding and colliding with other objects during transportation to produce scratches, affecting the production quality of the light guide plate.

[0014] 1. The light guide plate feeder with clamping protection, in order to prevent the light guide plate from sliding during transportation, before conveying the light guide plate, first plug the light guide plate into the clamping frames on both sides, and start the bidirectional stepping motor on the upper side of the installation base plate, the output ends of the bidirectional stepping motor on both sides drive the rotating rod connected thereto to rotate through the coupling, and then drive the internal threaded barrel to rotate through the transmission action of the driving roller and the driving belt, and when the internal threaded barrel rotates, it acts on the internal external threaded rod thread, thereby driving the two clamping frames to move relative to each other to clamp and limit the light guide plate. The light guide plate feeder with clamping protection can prevent the light guide plate from sliding and deflecting during movement by clamping and limiting the two sides of the light guide plate, reduce the contact and collision of the light guide plate with other objects, and thus effectively protect the light guide plate to achieve the effect of position limiting protection;

[0015] 2. In order to improve the feeding effect of the light guide plate, the light guide plate feeder with clamping protection starts the electric rod installed in the middle of the clamping frame after the light guide plate is limited. The electric rod starts to push the mounting plate inside the mounting groove to the side where the light guide plate is located until the electric auxiliary roller on the inside of the mounting plate abuts against the edge of the light guide plate. At this time, the electric auxiliary roller is started to assist the electric feeding roller to achieve stable and efficient transportation of the light guide plate. The light guide plate feeder with clamping protection is provided with two sets of feeding structures. The two sets of feeding results cooperate with each other to further improve the feeding efficiency of the light guide plate. BRIEF DESCRIPTION OF THE DRAWINGS
