Description

Technical Field

[0001] The utility model relates to an anti-paper jam structure for a paper feeding platform of a paper separator, belonging to the technical field of paper separators. Background Art

[0002] A paper separator is a device used to separate large sheets of paper into smaller pieces. It is commonly used in offices, printing shops, and other places that handle large quantities of paper. A paper separator can quickly and accurately cut large sheets of paper into the desired size, improving work efficiency. Some paper separators also feature automatic paper feeding and cutting functions, making operation more convenient and faster. Furthermore, the cutting thickness and speed can be adjusted to accommodate different paper types and thicknesses.

[0003] During the use of existing paper separators, cardboard is generally stacked on the paper feeding platform and then manually pushed into the paper separator. However, when the equipment is running, the position of the paper feeding platform is fixed, which makes it easy for the lightweight cardboard stacked on the paper feeding platform to get stuck at both ends and unable to descend when being fed out. Therefore, it is urgent to improve the structure of the paper feeding platform to prevent paper jams. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide an anti-paper jam structure for a paper feeding platform of a paper separator to prevent the occurrence of paper jams.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0006] A paper jam prevention structure for a paper feeding platform of a paper separator, comprising:

[0007] A paper feeding platform is slidably connected to the front side wall of the paper separator body, and a vibration component is connected between the paper feeding platform and the front side wall of the paper separator body;

[0008] A disassembly component is installed on the vibration component.

[0009] Preferably, the vibration component includes two symmetrically arranged sliders fixed on a side wall of the paper feeding platform close to the front side wall of the paper separator body. The cross-section of the sliders is a convex structure, and the sliders are slidably connected in the slide groove provided on the front side wall of the paper separator body.

[0010] Preferably, the bottom end of the slider is movably connected with a spring, and the bottom end of the spring is fixed with an insert block with an I-shaped cross-section. The insert blocks are movably inserted into slots provided on the front side wall of the paper splitter body, and the slots are connected to the corresponding slide grooves. The insert blocks are threaded with a hand screw a, and one end of the hand screw a after being tightened is threadedly connected to the screw hole provided on the inner wall of the slot.

[0011] Preferably, a U-shaped rod is fixed to the bottom end of the paper feeding platform, and a cam is movably overlapped on the inner bottom wall of the U-shaped rod. The cam is installed on the outside of the output shaft of the motor through a disassembly part, and the motor is fixed on the front side wall of the paper separator body.

[0012] Preferably, the disassembly and assembly part includes a spline sleeve fixed in the camshaft hole, and a limit block with a circular vertical cross-section is fixed to the outer side of the output shaft of the motor, and the side of the limit block facing away from the motor is movably overlapped with one end of the spline sleeve.

[0013] Preferably, a plurality of spline bars arranged in a ring array are fixedly connected to the outer side of the output shaft of the motor, and the spline sleeve is movably mounted on the plurality of spline bars and the outer side of the output shaft.

[0014] Preferably, a hand screw b is threadedly connected to the spline sleeve, and one end of the hand screw b is pressed against the outer side of the output shaft after being locked.

[0015] The beneficial effects of the utility model are:

[0016] (1) The vibration component provided by the utility model, when the motor is started, causes the cam to rotate, and cooperates with the action of the U-shaped rod and the two springs, so that the paper feeding platform can be shaken up and down on the front side wall of the paper separator through the two sliders, so that the lightweight cardboard stacked on the paper feeding platform is not easily stuck at both ends and cannot be lowered when being fed out, effectively ensuring the stability during manual paper feeding.

[0017] (2) Through the disassembly and assembly parts provided by the present invention, when the springs need to be replaced, the two hand screws a can be loosened, so that the two springs can be easily replaced after long-term use, avoiding elastic failure caused by long-term use. Secondly, the rotational movement of the cam causes continuous friction between the U-shaped rod and it. When the cam needs to be replaced, the cam fixed to the outside of the spline sleeve can be removed from the multiple spline bars and the outside of the output shaft by loosening the hand screws b, thereby facilitating the replacement of the cam and being easy to use.
