Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a cutting machine which is convenient for replacing a cutting blade. Background Art

[0002] As the name suggests, a cutting machine refers to a machine used to cut materials. It is a processing machine used to punch various flexible materials in industrial production.

[0003] The cutting heads used in existing cutting machines are fixed with bolts during installation. When the blade is damaged, the efficiency of replacing the blade is extremely low, which greatly affects the processing efficiency of the cutting machine. Moreover, if the blade is damaged during the cutting process, the material cannot be cut continuously. If the blade is replaced before cutting, the position of the blade relative to the material may not be on the previous cutting gap, which has an adverse effect on the quality of the processed material. To this end, we propose a cutting machine that is easy to replace the cutting head to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments.

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-4 The utility model is described in further detail.

[0026] Embodiment 1, refer to Figure 1-2 In this embodiment, in order to solve the problem that the cutting heads used in the existing cutting machines have low replacement efficiency, which greatly affects the processing efficiency of the cutting machines, and if the blade is damaged during the cutting process, the material cannot be cut continuously. If the material is cut after replacement, the position of the blade relative to the material may not be on the previous cutting gap, which has an adverse effect on the quality of the processed material. The utility model discloses a cutting machine that is convenient for replacing the cutting heads, including a workbench 1, and a cutting table 5 is provided on the upper end surface of the workbench 1. The cutting table 5 is plane-processed to facilitate the placement of the workpiece. A cutting groove 51 is provided on the cutting table 5, and the cutting groove 51 can make it easy to make way for the cutting knife. During the actual cutting process, the cutting knife is inserted into the cutting groove 51.

[0027] like Figure 1 , Figure 2 and Figure 3 A lifting assembly 2 is fixedly installed on the upper end of the workbench 1, and the lifting assembly 2 can provide driving force for the up and down movement of the cutting knife.

[0028] Specifically, the lifting assembly 2 includes a reduction motor 22, and the reduction motor 22 is connected to the control switch through a wire. The cutting groove 51 is arranged directly below the reduction motor 22. A support plate 27 for the reduction motor 22 is arranged on the workbench 1, and the support plate 27 can facilitate the auxiliary support of the reduction motor 22, so that the reduction motor 22 is fixed more stably.

[0029] Furthermore, a sliding seat 21 is threadedly connected to the output shaft of the reduction motor 22, a connecting terminal 25 is fixedly installed at the lower end of the sliding seat 21, and guide rods 23 are fixedly installed on the left and right sides of the upper end of the sliding seat 21, and the guide rods 23 are movably plugged into the workbench 1. After the reduction motor 22 is turned on, the output shaft of the reduction motor 22 rotates, and through the threaded connection between the output shaft of the reduction motor 22 and the sliding seat 21, and the guiding effect of the guide rods 23, at this time, the sliding seat 21 moves upward or downward along the output shaft of the reduction motor 22.

[0030] like Figure 1 and Figure 4 As shown, a cutter disc assembly 3 is connected and installed below the lifting assembly 2, and the cutter disc assembly 3 can facilitate the switching of the cutter head of the cutting machine.

[0031] Specifically, the cutter disc assembly 3 includes a cutter disc 31, on which a guide rod 32 is distributed in an annular shape. The guide rod 32 is fixedly mounted to the cutter disc 31, and the outer diameter of the guide rod 32 is equal to the inner diameter of the connecting end 25. The guide rod 32 is movably inserted into the connecting end 25, and the connecting end 25 and the output shaft of the reduction motor 22 are colinear. A cutting knife 33 is installed at the lower end of the cutter disc 31 by screw connection, and the cutting knife 33 is arranged below the cutter disc 31. The cutting knives 33 are distributed in an annular shape on the cutter disc 31. Before the cutting machine is used, multiple cutting knives can be installed on the cutter disc 31. During the cutting process, if the blade is damaged, the cutter disc 31 is rotated to replace another unused cutting knife, thereby further improving the cutting efficiency of the cutting knife.

[0032] In this example, a support seat 24 is fixedly mounted on the rear end of the sliding seat 21. The setting of the support seat 24 can space the center line of the knife disc 31 from the center line of the connecting end 25, thereby facilitating the switching of the cutting knife 33.

[0033] Furthermore, an adjusting rod 26 is rotatably connected to the upper end of the support seat 24, and a hole groove for the adjusting rod 26 to be inserted is provided on the support plate 27. A threaded sleeve 34 is threadedly connected to the lower part of the adjusting rod 26, and the threaded sleeve 34 is connected to the cutter disc 31 through a bearing. After the cutter disc 31 is restricted from rotating, a rotational driving force is provided to the threaded sleeve 34. Through the rotation of the threaded sleeve 34, the cutter disc 31 can be driven to move downward along the center line of the adjusting rod 26, so that the guide rod 32 is easily detached from the inside of the connecting end 25; after the guide rod 32 is detached from the inside of the connecting end 25, the cutter disc 31 is rotated, and only the switching operation of the cutting knife 33 is required. The switching can effectively ensure the position of the cutting knife 33 relative to the workpiece, further ensuring the processing effect of the workpiece.

[0034] The specific working principle is: this kind of cutting machine which is convenient for replacing the cutting blade head, when in use, before the cutting machine is used, multiple cutting blades can be installed on the blade disc, and in the cutting process, if the blade is damaged, the reduction motor 22 is stopped, the blade disc 31 is supported, and the blade disc 31 is restricted to rotate with the threaded sleeve 34; the threaded sleeve 34 is provided with a rotational driving force, and the rotation of the threaded sleeve 34 can drive the blade disc 31 to move downward along the center line of the adjusting rod 26, so that the guide rod 32 is easy to be separated from the inside of the connecting terminal 25; after the guide rod 32 is separated from the inside of the connecting terminal 25, the adjusting rod 26 is rotated to replace the position of the cutting blade 33, so that the unused cutting blade 33 corresponds to the upper and lower positions of the connecting terminal 25; the threaded sleeve 34 is rotated in the opposite direction, and the guide rod 32 of the unused cutting blade 33 can be inserted into the inside of the connecting terminal 25, so that the cutting processing needs of the cutting machine can be carried out.

[0035] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
