[0002] The cutting head is one of the most critical components of the cutting equipment. It is mainly used to cut various materials. It is similar to the "head" of the equipment and contains cutting blades and related devices to drive the blades. Its function is to precisely cut materials according to preset shapes, sizes and paths to meet the needs of different product manufacturing.

[0003] Current fabric cutting heads use blades to move up and down to cut the fabric, while cylinders drive pressure plates to move up and down to press fabrics of different thicknesses for easy cutting. However, current cutting heads are noisy and resonate during use, which causes additional vibration and displacement of the cutting head during the cutting process.

[0004] Therefore, it is necessary to provide an easily adjustable cutting head to solve the above-mentioned technical problems. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] First Embodiment

[0028] Please refer to the following: Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a cutting head that is easy to adjust, provided by this utility model; Figure 2 for Figure 1 The diagram shows a side view of the frame. An easily adjustable cutting head includes:

[0029] A frame 1, a sharpening assembly 5 is provided at the bottom of the frame 1, a locking assembly 6 is provided at the bottom of the frame 1, and a motor 8 is fixedly installed on the surface of the frame 1.

[0030] The balancing component 2 is disposed on one side of the frame 1. The balancing component 2 includes three pulleys 21, the surface of the pulleys 21 is provided with belts 22, the surface of the belts 22 is provided with eccentric wheels 23, and a connecting rod 24 is rotatably connected to one side of the eccentric wheel 23.

[0031] Cutting tool 3 is disposed at one end of the connecting rod 24;

[0032] Rotating component 4 is disposed at the bottom of the frame 1, and a cutter head assembly 7 is disposed at the bottom of the rotating component 4.

[0033] All three pulleys 21 are rotatably connected to one side of the frame 1, and the three pulleys 21 are driven by belts 22, and an eccentric wheel 23 is fixedly connected to one side of one pulley 21.

[0034] One of the three pulleys 21 is a pulley with two grooves, used for connection with the motor 8.

[0035] The output end of the motor 8 is connected to a pulley 21 through a transmission component, so that after the motor 8 starts, it drives the pulley to rotate to one side. The transmission component can be a pulley with a belt, a chain wheel with a chain, or a synchronous belt with a synchronous pulley.

[0036] The sharpening assembly 5 is used to sharpen the cutting tool 3 by means of a motor driving the sharpening process.

[0037] Rotating component 4 is used to change the cutting direction of the blade.

[0038] The cutter head assembly 7 is used to hold the fabric in place, prevent the fabric from becoming loose, and guide the cutting head.

[0039] One end of the connecting rod 24 is rotatably connected to the inside of the cutting tool 3.

[0040] The working principle of the easily adjustable cutting head provided by this utility model is as follows:

[0041] In use, when the motor 8 is started, the transmission component connected to the pulley 21 is rotated, causing the belt 22 to rotate to one side, which in turn drives the eccentric wheel 23 to rotate to one side. When the eccentric wheel 23 rotates to one side, it drives one end of the connecting rod 24 to move, thereby causing the cutter 3 to move up and down to cut the fabric.

[0042] Compared with related technologies, the easily adjustable cutting head provided by this utility model has the following advantages:

[0043] Beneficial effects:

[0044] This utility model provides an easily adjustable cutting head. Through the balancing component 2 and the motor 8, the cutter 3 moves up and down to cut the fabric. By using the eccentric wheel 23 driven by the belt 22, the motor speed can be increased, the noise generated by the cutting head can be reduced, the resonance phenomenon can be balanced, and the cutting quality can be improved. The motor 8 is fixed on the frame 1, which can effectively reduce the weight of the balancing component 2, making the cutting speed faster and more stable.

[0045] Second Embodiment

[0046] Please refer to the following: Figure 3 , Figure 4 and Figure 5 Based on the easily adjustable cutting head provided in the first embodiment of this application, the second embodiment of this application proposes another easily adjustable cutting head. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0047] Specifically, the second embodiment of this application provides an adjustable cutting head that differs in that the blade sharpening assembly 5 has two positioning grooves 9 inside, and positioning blocks 91 are slidably connected inside both positioning grooves 9.

[0048] Both positioning blocks 91 have a limiting groove 10 inside, and both limiting grooves 10 are slidably connected to a limiting block 11.

[0049] Two positioning blocks 91 are rotatably connected to the tops of the two whetstones of the whetstone assembly 5, and two positioning grooves 9 are opened inside the mounting bracket of the whetstone assembly 5. At the same time, two limiting grooves 10 are also opened inside the mounting bracket. After the two limiting blocks 11 are inserted into the two limiting grooves 10, they limit the positioning blocks 91.

[0050] A connecting plate 12 is fixedly connected to one side of the limiting block 11, and a fixing member 13 is provided inside the connecting plate 12.

[0051] One end of each of the two limiting blocks 11 is fixedly connected to one side of the connecting plate 12, and is located at both ends of the connecting plate 12 respectively.

[0052] The connecting plate 12 is used to simultaneously move the two limiting blocks 11 to one side when the connecting plate 12 moves to one side.

[0053] The fastener 13 includes a fixing hole, and a fixing pin is threaded into the fixing hole.

[0054] The fixing pin is a bolt, and the connecting plate 12 and the grinding tool assembly 5 are both provided with fixing holes that are compatible with the fixing pin. After the fixing pin is installed into the fixing hole, the connecting plate 12 and the grinding tool assembly 5 are fixed together.

[0055] The working principle of the easily adjustable cutting head provided by this utility model is as follows:

[0056] In use, after removing the fixing piece 13, moving the connecting plate 12 to one side causes the two limiting blocks 11 to move to one side, thus separating them inside the two limiting grooves 10. Then, moving the two sharpening stones of the sharpening assembly 5 downwards simultaneously causes the two positioning blocks 91 to move downwards inside the two positioning grooves 9, thus separating them and allowing the two sharpening stones to be detached.

[0057] When installing the two whetstones, insert the two positioning blocks 91 into the two positioning slots 9 respectively, insert the two limiting blocks 11 into the two limiting slots 10 respectively, move them to the appropriate position to one side, and then install the fixing piece 13.

[0058] Compared with related technologies, the easily adjustable cutting head provided by this utility model has the following advantages:

[0059] Beneficial effects:

[0060] This utility model provides an easily adjustable cutting head. By using the positioning groove 9 in conjunction with the positioning block 91, the limiting groove 10, the limiting block 11, the connecting plate 12, and the fixing member 13, the sharpening stone of the sharpening assembly 5 can be replaced, thereby making it convenient and quick to replace the two sharpening stones.

[0061] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
