Description

Technical Field

[0001] The utility model relates to the technical field of test paper folding, in particular to an eight-fold test paper folding machine. Background Art

[0002] The practice test papers used by students nowadays are generally made up of multiple octave test papers bound together into a booklet. When using, several sheets are torn off as needed. Before binding the test papers into a book, they generally need to be folded. However, traditional manual folding is inefficient and the folding is not neat. In order to avoid this situation, most manufacturers use paper folding machines to fold the test papers and then bind them.

[0003] For example, Chinese patent announcement No. CN219058081U discloses a high-speed paper folding machine. When in use, the telescopic feeding plate is first driven to turn to the stacking mechanism through the rotating mechanism, and the previously prepared stacking material is pushed to the top of the telescopic feeding plate by the pushing plate, and the moving seat is driven to move by the moving driving mechanism. At the same time, the rotating mechanism turns the telescopic feeding plate to the direction of the material placement plate, and the material is sent to the top of the material placement plate by the telescopic rod. The positioning stud in the material placement and unloading mechanism descends and adapts to the avoidance groove. After passing through the avoidance groove, the telescopic rod drives the telescopic feeding plate to be retracted, and the positioning stud blocks the material so that it falls on the top of the material placement plate, completing the loading; when the equipment needs to be moved, the telescopic oil cylinder is started to extend the universal wheel to contact the ground, and the supporting foot is propped up to move the equipment, and the universal wheel can be retracted after the movement is completed.

[0004] However, the high-speed paper folding machine in the above application uses a push plate to push the paper during the feeding process, which may cause the paper to curl during the pushing process, thereby affecting the subsequent folding process. Therefore, there are certain limitations.

[0005] To this end, we urgently need to provide an eight-fold test paper folding machine. Utility Model Content

[0006] The purpose of the utility model is to provide an eight-fold test paper folding machine to solve the problem that the high-speed paper folding machine proposed in the above-mentioned background technology adopts a push plate to push the feeding method during the feeding process, which may cause the paper to curl during the pushing process, thereby affecting the subsequent folding.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an eight-fold test paper folding machine, comprising a conveying platform and a support frame, the support frame is installed on the left side of the conveying platform, a loading device is arranged above the conveying platform, and a folding device is arranged above the support frame.

[0008] The feeding device comprises a storage unit and a feeding unit.

[0009] The material storage unit includes a conveyor belt, a paper material box, a paper outlet, and an observation window. The conveyor belt is installed inside the conveyor platform, the paper material box is fixedly connected to the right side of the upper surface of the conveyor platform, the paper outlet is opened at the bottom of the left outer surface of the paper material box, and the observation window is installed at the center of the right outer surface of the paper material box. The eight-fold test paper is placed inside the paper material box, and then the conveyor belt is started by the power component. The test paper is output from the paper outlet on the left side of the bottom of the paper material box through the conveyor belt. The material is continuously loaded, which improves the efficiency of folding and rolling. The setting of the observation window can observe the remaining amount of the test paper inside the paper material box in real time, and the test paper can be added in time.

[0010] A further improvement is that the feeding unit includes a stretching assembly, a rotating bearing, a rotating shaft, and a pressing wheel. Two groups of the stretching assemblies are respectively installed on the front and rear sides of the upper surface of the conveying platform. The two rotating bearings are respectively fixedly connected to the top of the stretching assembly. The front and rear ends of the rotating shaft are respectively rotatably connected to the inside of the rotating shaft. Five pressing wheels are equidistantly fixedly connected to the outer surface of the rotating shaft. The test paper is conveyed to the left through the conveyor belt. The friction force of the test paper drives the rotating shaft inside the pressing wheel to rotate inside the rotating bearing, so that the test paper is limited and flattened by the pressing wheel to prevent it from curling and affecting subsequent processing.

[0011] A further improvement is that the stretching assembly includes a stretching spring, a limiting sleeve, and a limiting slide rod, the stretching spring is fixedly connected between the conveying platform and the rotating bearing, the limiting sleeve is fixedly connected to the upper surface of the conveying platform and is located inside the stretching spring, the limiting slide rod is slidably connected to the inside of the limiting sleeve, and its top is fixedly connected to the rotating bearing. In order to ensure that there is a certain friction between the pressing wheel and the test paper, the rotating bearing is pulled downward by the elasticity of the stretching spring, thereby pulling the pressing wheel downward so that it is attached to the surface of the test paper. The elasticity of the stretching spring can be used to adapt to test papers of different thicknesses, thereby improving the applicability of the device.

[0012] A further improvement is that the five groups of feeding units are equidistantly installed on the upper surface of the conveying platform, and limit and flatten the test paper throughout the entire process of conveying the test paper to avoid curling of the test paper.

[0013] A further improvement is that the folding device comprises a folding unit and a rolling unit;

[0014] The folding unit includes a mounting frame, an electric lifting rod, and a folding plate. The mounting frame is fixedly connected to the top right side of the support frame, the electric lifting rod is installed on the lower surface of the mounting frame, and the folding plate is fixedly connected to the bottom of the electric lifting rod.

[0015] A further improvement is that the winding unit includes a synchronous motor, a fixed bearing seat, a rotating shaft, and a winding roller, the synchronous motor is installed at the top front end of the support frame, the fixed bearing seat is fixedly connected to the right side of the top front end of the support frame, the rotating shaft is connected to the output end of the synchronous motor and is rotatably connected to the inside of the fixed bearing seat, and the winding roller is fixedly connected to the right side of the outer surface of the rotating shaft.

[0016] A further improvement is that two sets of winding units are symmetrically installed at the front and rear ends of the support frame with the center line of the support frame as the axis, and the folding plate vertically corresponds to the gap between the two winding rollers. When the test paper is transported to the winding rollers, the synchronous motor is started to drive the rotating shaft to rotate inside the fixed bearing seat, thereby driving the winding roller outside the rotating shaft to rotate downward, and at the same time, the electric lifting rod is started to drive the folding plate to move downward, so that the test paper is pressed and folded.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] 1. The eight-fold test paper folding machine places the eight-fold test paper inside the paper box, and then starts the conveyor belt through the power component. The test paper is output from the paper outlet on the left side of the bottom of the paper box through the conveyor belt. The material is continuously loaded, which improves the folding efficiency. The setting of the observation window can observe the remaining amount of the test paper inside the paper box in real time, and add the test paper in time.

[0019] 2. In this eight-fold test paper folding machine, the test paper is conveyed to the left through a conveyor belt. The friction of the test paper drives the rotating shaft inside the pressure wheel to rotate inside the rotating bearing, so that the test paper is limited and flattened by the pressure wheel to avoid folding and affecting subsequent processing.

[0020] 3. In order to ensure a certain friction between the pressure wheel and the test paper, the eight-fold test paper folding machine uses the elasticity of the stretch spring to pull the rotating bearing downward, thereby pulling the pressure wheel downward to make it adhere to the surface of the test paper. The elasticity of the stretch spring can be used to adapt to test papers of different thicknesses, thereby improving the applicability of the device.

[0021] 4. For this eight-fold test paper folding machine, when the test paper is transported to the winding roller, the synchronous motor is started to drive the rotating shaft to rotate inside the fixed bearing seat, thereby driving the winding roller outside the rotating shaft to rotate downward, and at the same time, the electric lifting rod is started to drive the folding plate to move downward, thereby pressing and folding the test paper.
