Description

Technical Field

[0001] This utility model relates to the field of printing and die-cutting machine technology, specifically to a flywheel lubrication device for the main body of a printing and die-cutting machine. Background Technology

[0002] Die-cutting machines, also known as die-cutting machines or CNC punching machines, are mainly used for die-cutting, creasing, hot stamping, laminating, and automatic waste removal of non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic products, mobile phone pads, etc. They utilize steel blades, metal molds, and steel wire, applying pressure through a printing plate to cut printed materials or cardboard into specific shapes.

[0003] For example, a flywheel lubrication device for the main body of a printing and die-cutting machine, with authorization announcement number "CN216715114U," uses a circulating oil replenishment component to periodically replenish oil to the bearings, ensuring effective lubrication, significantly extending bearing life, eliminating the need for frequent bearing replacements, and improving processing efficiency. However, while this device extends bearing life through circulating oil replenishment, after each oil spraying lubrication, lubricating oil leaks from the bearings, leaving them in a state of insufficient lubrication after a period of use, resulting in poor lubrication performance. Utility Model Content

[0004] The purpose of this invention is to solve the problem of poor lubrication effect of the device, and to propose a flywheel lubrication device for the main body of a printing die-cutting machine.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a flywheel lubrication device for the main body of a printing die-cutting machine, including a main shaft and a flywheel. The outer wall of the main shaft is rotatably connected to the flywheel through a bearing. The outer wall of the main shaft is symmetrically provided with grooves. The flywheel is symmetrically provided with retraction structures at both ends. The main shaft abuts against the inner walls of two sets of first semicircular frames and second semicircular frames respectively through the grooves on its surface. One end of the first semicircular frame and the second semicircular frame abuts against each other.

[0007] Preferably, the recycling structure includes a support plate and a ring. One end of the ring is pressed against the flywheel. The outer wall of the ring is symmetrically fixed with support plates. Each support plate is fitted with two bolts through through holes on its surface. One end of each bolt on both sides is threadedly connected to the flywheel.

[0008] Preferably, the outer walls of the first and second semicircular frames are each fixedly connected with a plurality of through-hole blocks, and the plurality of through-hole blocks are all abutted together by screws and nuts.

[0009] Preferably, oil pipes are symmetrically fixedly connected to the outer walls of the first semicircular frames on both sides, and one end of each of the oil pipes passes through the first semicircular frame.

[0010] Preferably, one end of both the first and second semicircular frames is in contact with the flywheel, and a rubber pad is provided between the first and second semicircular frames.

[0011] This utility model proposes a flywheel lubrication device for the main body of a printing and die-cutting machine. Its advantages are as follows: through the cooperation of the recovery structure and the flywheel, lubricant is sprayed into the bearing inside the flywheel via an oil pipe, thus lubricating the flywheel. The lubricating oil inside the bearing flows out under the action of the flywheel's rotation and gravity. The inclined surfaces of the inner walls of the two circular rings help retain the lubricating oil, allowing excess lubricating oil to still contact the bearing. The rotation of the bearing ensures that the balls inside the bearing are in complete contact with the lubricating oil, maintaining a constant lubrication effect. By retaining the lubricating oil, the bearing remains lubricated during use, improving the device's lubrication efficiency. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] See attached document Figure 1-6In this embodiment, a flywheel lubrication device for the main body of a printing die-cutting machine includes a main shaft 1 and a flywheel 7. The outer wall of the main shaft 1 is rotatably connected to the flywheel 7 through a bearing. The outer wall of the main shaft 1 is symmetrically provided with grooves. The flywheel 7 is symmetrically provided with a retraction structure 2 at both ends. The main shaft 1 abuts against the inner walls of two sets of first semicircular frames 6 and second semicircular frames 4 through the grooves on its surface. One end of the first semicircular frame 6 and the second semicircular frame 4 abuts against each other.

[0021] Multiple through-hole blocks 3 are fixedly connected to the outer walls of the first semicircular frame 6 and the second semicircular frame 4. The multiple through-hole blocks 3 are all abutted by screws and nuts. Oil pipes 5 are symmetrically fixedly connected to the outer walls of the first semicircular frame 6 on both sides. One end of the multiple oil pipes 5 passes through the first semicircular frame 6. One end of the first semicircular frame 6 and the second semicircular frame 4 are in contact with the flywheel 7. A rubber pad is provided between the first semicircular frame 6 and the second semicircular frame 4.

[0022] The recycling structure 2 includes a support plate 202 and a ring 203. One end of the ring 203 is pressed against the flywheel 7. The support plate 202 is symmetrically fixed to the outer wall of the ring 203. The support plate 202 is respectively attached to two bolts 201 through through holes opened on its surface. One end of the bolts 201 on both sides is threadedly connected to the flywheel 7.

[0023] Working principle:

[0024] When lubricating the flywheel of the main unit of the printing and die-cutting machine:

[0025] The main shaft 1 of this device is installed at the center of the main body of the printing and die-cutting machine.

[0026] Installation process:

[0027] The operator places the two rings 203 onto the surface of the main shaft 1 and fixes the four support plates 202 to the surface of the flywheel 7 with four bolts 201. During the high-speed punching stage of the printing die-cutting machine, the flywheel 7 is used to maintain the stable speed of the main shaft 1 and avoid problems such as blade skipping and plate clogging caused by uneven material thickness, tool wear, or fluctuations in feeding speed. The two rings 203 can be fixed to the surface of the flywheel 7. The rubber gasket can seal between the rings 203 and the flywheel 7. The operator places the inner walls of the first semicircular frame 6 and the second semicircular frame 4 into the grooves on the surface of the main shaft 1, and at the same time, makes one end of the first semicircular frame 6 and the second semicircular frame 4 press against each other and seals them with rubber gaskets. The operator fixes the through-hole blocks 3 on the surface of the first semicircular frame 6 and the second semicircular frame 4 with four sets of bolts and nuts, so that the through-hole blocks 3 on both sides can limit the first semicircular frame 6 and the second semicircular frame 4 to the surface of the main shaft 1.

[0028] Lubrication process:

[0029] The external oil pump draws lubricating oil from the external container and transports it into the interior of oil pipe 5. The lubricating oil is then sprayed into the bearings inside the flywheel 7 through oil pipe 5. The external oil pump is periodically activated to lubricate the flywheel 7. The lubricating oil inside the bearings flows out under the rotation of the flywheel 7 and the force of gravity. The inclined surfaces of the inner walls of the two side rings 203 help retain excess lubricating oil, allowing it to contact the bearings again. The rotation of the bearings ensures that the balls inside the bearings are fully in contact with the lubricating oil. The contact maintains a constant lubrication effect. When there is too much excess lubricating oil, it will overflow from the ring 203 and enter the grooves inside the first semicircular frame 6 and the second semicircular frame 4. The operator periodically disassembles the first semicircular frame 6 and the second semicircular frame 4. A rubber plug is provided on the lower inner wall of the first semicircular frame 6 (it can be connected by compression, or if necessary, by threaded connection to ensure that the rubber plug is below the first semicircular frame 6). Pulling out the rubber plug will allow the internal lubricating oil to flow out and recover the excess lubricating oil.

[0030] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
