Description

Technical Field

[0001] The invention belongs to the technical field of cutting machines, and in particular relates to a paper pressing and feeding structure of a cutting machine workbench. Background Art

[0002] The cutting machine is a directional cutting machine with pre-planned cutting paths and contents. These cutting paths and contents have been written into software and stored by software engineers. The two-digit code corresponding to the cutting content is printed on the paper to be cut. Before the equipment cuts, there is a movable cutting tool, creasing tool, and video detection camera on the equipment. During the inspection process, the two-dimensional code is read to retrieve the stored cutting content and cutting trajectory, and then the program is executed to perform cutting, creasing, and other tasks until the work is completed.

[0003] The workbench arranged on the cutting machine is mainly used for conveying paper. The existing workbench does not exert uniform pressure on the paper during the paper feeding process, and the paper is prone to deviation, which will cause cutting errors during cutting, resulting in relatively large cutting errors. Therefore, it is necessary to develop a new workbench to improve it. Summary of the invention

[0004] The purpose of the present invention is to provide a paper pressing and feeding structure for a cutting machine workbench, which overcomes the shortcomings of the prior art and adopts multiple sets of paper pressing wheel structures to solve the problem of uneven paper pressing force causing paper deviation during the cutting process, thereby affecting the cutting quality; multiple sets of adjustable compression springs apply pressure to the end bearing of the upper paper pressing shaft assembly, which can be adjusted to a suitable pressing force as needed.

[0005] To solve the above problems, the technical solutions adopted by the present invention are as follows:

[0006] A paper pressing and feeding structure for a cutting machine workbench comprises an X-axis driving mechanism, a Y-axis driving mechanism, a paper feeding mechanism, a working platform and a pressure regulating mechanism.

[0007] The X-axis driving mechanism includes a secondary synchronous pulley, a secondary synchronous belt, a primary synchronous pulley, a primary synchronous belt and an X-axis driving motor.

[0008] The Y-axis driving mechanism includes a cutting trolley, a Y-axis driving motor and a crossbeam assembly. The cutting trolley is mounted on the crossbeam assembly through a track and is controlled by the Y-axis driving motor to move along the track.

The upper paper pressing shaft assembly is provided with a plurality of rubber wheels, and the lower paper pressing shaft assembly is provided with a plurality of thorn wheels.

[0010] The upper paper pressing shaft assembly and the lower paper pressing shaft assembly cooperate to form a paper pressing wheel structure. The paper pressing wheel structure is divided into multiple groups. The lower paper pressing shaft assembly on the multiple paper pressing wheel structures is fixed by a lower paper pressing bearing seat, and one end thereof extends to the outside of the lower paper pressing bearing seat and is connected to multiple primary synchronous pulleys through multiple secondary synchronous belts and multiple secondary synchronous belts. The multiple primary synchronous belt pulleys are connected to the X-direction drive motor through the primary synchronous belt.

[0011] End bearings are arranged at both ends of the upper paper pressing shaft assembly. The pressure regulating mechanism is arranged above the end bearings and is pressed on the end bearings to apply pressure to the end bearings of the upper paper pressing shaft assembly.

[0012] Furthermore, the primary synchronous pulley is a tensioning pulley, and the tensioning pulley is fixed by a tensioning pulley bracket.

[0013] Furthermore, the pressure regulating mechanism includes a pressure regulating bolt, a pressure spring, a guide column, a pressure block, a slide plate, an upper fixed plate, a lower fixed plate and a side wall plate. The lower fixed plate is installed on the working platform. A plurality of slots are arranged on the lower fixed plate. The end bearings are respectively arranged in the slots. The upper fixed plate is a C-shaped structure. The slide plate is arranged inside the upper fixed plate through the guide column and moves up and down along the guide column. A making way slot for the slide plate is arranged below the C-shaped structure. A plurality of conical holes are arranged on the slide plate. The pressure block is a conical structure adapted to the conical hole. The pressure block is installed at the position of the conical hole and extends out of the conical hole at the lower end. The upper end of the pressure regulating bolt is fixed above the C-shaped structure through a sliding sleeve, and the lower end is connected to the pressure block. The pressure spring is sleeved on the pressure regulating bolt.

[0014] Furthermore, the pressure regulating mechanism also includes a resistance tension spring, a switching handle, connecting bolt one and connecting bolt two. The middle of the switching handle is movably connected to the upper fixed plate through connecting bolt one, and the lower end is movably connected to the slide plate through connecting bolt two. The upper end of the switching handle is connected to the slide plate through a resistance tension spring. Under the action of the resistance tension spring, the switching handle is used to control the lifting and lowering of the pressure block. When lifting, it is convenient to disassemble and assemble the upper paper pressing shaft assembly. When lowering, the pressure block presses on the end bearing to fix the paper pressing shaft assembly.

[0015] Furthermore, the lower surface of the pressing block is an arc-shaped structure that cooperates with the end bearing.

[0016] Furthermore, the paper pressing wheel structure is composed of four groups.

[0017] Furthermore, the four groups of paper pressing wheel structures include three groups of paper pressing wheel structures located at the front and one group of paper pressing wheel structures located at the rear.

[0018] Furthermore, the four groups of paper pressing wheel structures include two groups of paper pressing wheel structures located at the front and two groups of paper pressing wheel structures located at the rear.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The use of multiple sets of paper pressing wheel structure solves the problem of uneven paper pressing force causing paper cutting process deviation, thus affecting the cutting quality;

[0021] 2. Use multiple sets of adjustable compression springs to apply pressure to the end bearing of the upper paper pressing shaft assembly, which can be adjusted to the appropriate clamping force as needed;

[0022] 3. Use more integrated working platform components to reduce the impact of manufacturing accuracy issues on cutting quality;

[0023] 4. The X-axis drive system adopts a multi-stage synchronous pulley mechanism to make the equipment more compact and reduce costs; at the same time, it ensures that multiple sets of paper pressing wheels run synchronously.

[0024] 5. Multiple groups of paper pressing wheel structures can be accurately switched to different working states. By operating the switching handle, the paper feeding mechanism and pressure regulating mechanism can be quickly and accurately switched to the paper pressing state and replacement state at the same time.
