Description

Technical Field

[0001] This invention relates to the field of electric cutting shears, and more particularly to an electric cutting shear with laser-assisted function. Background Technology

[0002] Electric cutting shears are a common fabric cutting tool used in the garment industry. Currently, electric cutting shears on the market typically consist of a frame and blades driven by a motor mounted on the frame. When using electric cutting shears, cutting lines need to be drawn on the fabric with chalk, and then the electric cutting shears are used to cut along these lines to ensure they are horizontal. In factory processing, marking lines for each batch of fabric is cumbersome. Furthermore, when operating electric cutting shears, the cutting direction can only be determined by feel and observation of the blade position, resulting in inaccurate fabric cutting and making the shears inconvenient to use. Summary of the Invention

[0003] The present invention aims to solve the problems existing in the prior art by providing an electric cutting scissors with laser-assisted function. It eliminates the need to pre-mark the fabric and allows users to intuitively see the cutting direction of the scissors, making the fabric cutting more precise and convenient to use.

[0004] The technical solution adopted by this invention to solve its technical problem is as follows: This electric cutting shears with laser-assisted function includes:

[0005] The machine frame includes a main body, a drive motor mounted on the main body, with a rotating shaft extending outward from the drive motor, a blade mounted on the rotating shaft and rotating, and a cutting direction guide that forms a guiding light in the cutting direction in front of the blade; and an auxiliary mounting part for detachably fixing the cutting direction guide. The auxiliary mounting part has an inner cavity, a first opening for the cutting direction guide to enter the inner cavity, and a second opening for the guiding light of the cutting direction guide to pass through. A positioning mechanism for fixing the cutting direction guide in a fixed direction within the inner cavity is provided inside the inner cavity.

[0006] Preferably, the positioning mechanism includes an arcuate surface disposed on the inner wall of the receiving cavity, a cylindrical housing disposed on the cutting direction guide corresponding to the arcuate surface, a positioning slot formed on the inner wall of the receiving cavity, and a positioning protrusion disposed on the outer side of the cutting direction guide.

[0007] Preferably, the positioning protrusion includes a mounting groove formed on the outside of the cylindrical shell and surrounding the shell, and a limiting ring fitted inside the mounting groove, with the limiting ring protruding from the outer surface of the cylindrical shell.

[0008] Preferably, the auxiliary mounting part includes a connecting part that can be detachably mounted on the frame body and an auxiliary fixing part for mounting the cutting direction guide.

[0009] Preferably, the receiving cavity is formed within the auxiliary fixing part, the first opening is formed on the auxiliary fixing part and communicates with the receiving cavity, and the second opening is formed at the front end of the auxiliary fixing part and communicates with the receiving cavity.

[0010] Preferably, the front end of the frame body has a positioning and mounting groove corresponding to the connecting part, and the connecting part can be detachably installed in the positioning and mounting groove.

[0011] Preferably, the accommodating cavity includes a light source mounting cavity located at the bottom of the accommodating cavity and a guide mounting cavity located outside the light source mounting cavity, with an arc-shaped surface formed on the inner wall of the guide mounting cavity.

[0012] Preferably, a protective frame is installed on the main body of the frame, located outside the blade, and the protective frame is provided with a shield covering the first opening.

[0013] Preferably, the positioning mounting groove has screw holes, the connecting part has threaded holes corresponding to the screw holes, and the frame has fixing screws that pass through the screw holes and are threaded into the threaded holes.

[0014] Preferably, the positioning mounting groove has a wiring hole that connects to the inside of the frame, and the inner end of the connecting part has a channel corresponding to the wiring hole and connecting to accommodate the inner cavity.

[0015] The beneficial effects of this invention are as follows: A cutting direction guide and an auxiliary mounting part are installed at the front of the frame to accurately position and install the cutting direction guide so that a guiding light beam is formed in the cutting direction of the blade. The auxiliary mounting part has an arc-shaped surface that mates with the cutting direction guide of the cylindrical housing and a positioning groove that mates with the positioning protrusion on the outer side of the cutting direction guide. This ensures accurate installation and positioning of the cutting direction guide, thereby aligning the light emission point of the guiding light beam with the cutting direction of the blade. This allows the guiding light beam to be adjusted to coincide with the cutting direction of the blade, thus ensuring precise cutting. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] See attached document Figure 1 As shown: This embodiment discloses an electric cutting shear with laser-assisted function, including: a frame body 1,

[0025] The drive motor 2 is mounted on the frame body 1, the rotating shaft 3 is set in the drive motor 2 and extends outward, and the blade 4 is mounted on the rotating shaft 3 and rotates together with the rotating shaft 3; when in use, hold the frame body 1 by hand and move the frame body 1 by hand, so that the rotating blade 4 cuts the fabric below.

[0026] Since the cutting direction of the electric cutting shears is entirely controlled by the operator's hand, to further enhance the cutting accuracy of the electric cutting shears, the electric cutting shears in this embodiment also include a cutting direction guide 5 and an auxiliary mounting part 6; wherein, the cutting direction guide 5 is used to form a guiding light in the cutting direction in front of the blade 4; the auxiliary mounting part 6 is used to detachably fix the cutting direction guide 5, specifically, as shown in... Figure 4 As shown, the auxiliary mounting part 6 in this embodiment has an inner cavity 7, a first opening 8 for the cutting direction guide 5 to enter the inner cavity 7, and a second opening 9 for the guide light of the cutting direction guide 5 to pass through. A positioning mechanism for positioning the cutting direction guide 5 in a fixed direction in the inner cavity 7 is provided in the inner cavity 7.

[0027] Furthermore, such as Figure 4 and 5As shown, the positioning mechanism includes an arc-shaped surface 7-1 disposed on the inner wall of the receiving cavity 7, a cylindrical housing 7-2 disposed on the cutting direction guide 5 corresponding to the arc-shaped surface 7-1, a positioning slot 7-3 formed on the inner wall of the receiving cavity 7, and a positioning protrusion disposed on the outer side of the cutting direction guide 5; in this embodiment, the cutting direction guide 5 can be a light emitter, specifically an infrared emitter; for example Figure 3 and 5 As shown, during installation, the positioning protrusion engages with the positioning slot 7-3, limiting the cutting direction guide 5 in the front-to-back direction. Simultaneously, the outer surface of the cylindrical housing 7-2 on the cutting direction guide 5 contacts and positions itself against the arc-shaped surface 7-1, thereby ensuring accurate positioning of the cutting direction guide 5. Furthermore, by engaging the positioning protrusion with the positioning slot 7-3, the displacement of the cutting direction guide 5 in the front-to-back direction is limited.

[0028] Specifically, such as Figure 4 and 5 As shown, the auxiliary installation part 6 in this embodiment includes a connecting part 6-1 detachably mounted on the frame body 1 and an auxiliary fixing part 6-2 for mounting the cutting direction guide; wherein, the front end of the frame body 1 has a positioning mounting groove 10 corresponding to the connecting part 6-1, the connecting part 6-1 is detachably mounted in the positioning mounting groove 10, and in order not to affect the normal rotation of the blade 4, the height of the outer plane of the connecting part 6-1 is lower than or equal to the height of the outer plane of the frame body 1. At the same time, the connecting part 6-1 can be a square structure and a rounded chamfer is designed on one side edge of the connecting part 6-1, and the corresponding positioning mounting groove 10 is also set accordingly, thereby avoiding errors in the installation position and installation direction of the connecting part 6-1. The installation is more reasonable; and through the positioning mounting groove 10 and the connecting part 6-1 that matches the structure of the positioning mounting groove 10, the position of the auxiliary mounting part 6 is accurately installed, thereby further ensuring the accuracy of the installation position of the cutting direction guide 5; specifically, in this embodiment, the positioning mounting groove 10 has a screw hole 13, and the connecting part 6-1 has a threaded hole 14 corresponding to the screw hole 13. The frame 1 is provided with a fixing screw that passes through the screw hole 13 and is threaded into the threaded hole 14. The connecting part 6-1 is detachably installed on the frame 1 by the fixing screw. At the same time, the large end of the fixing screw is located inside the frame on the side away from the blade 4, thereby reducing the installation gap between the frame 1 and the blade 4 and preventing thin wires from getting stuck.

[0029] Correspondingly, the inner cavity 7 is formed within the auxiliary fixing part 6-2, the first opening 8 is formed on the auxiliary fixing part 6-2 and communicates with the inner cavity 7, and the second opening 9 is formed at the front end of the auxiliary fixing part 6-2 and also communicates with the inner cavity 7; based on this, in order to ensure the stable installation of the cutting direction guide 5, such as Figure 3As shown, in this embodiment, a protective frame 11 located outside the blade 4 is installed on the main body 1 of the frame. The protective frame 11 is provided with a shielding part 12 covering the first opening 8. The protective frame 11 is detachably connected to the main body 1 of the frame by screws, and the corresponding shielding part 12 covers the outside of the first opening 8 to limit the cutting direction guide 5, thereby preventing the cutting direction guide 5 from falling out of the first opening 8.

[0030] Specifically, in this embodiment, the right end of the cylindrical shell 7-2 is positioned and installed by contact between the positioning protrusion and the blocking part 12, thereby limiting the freedom of the cutting direction guide 5 in the front-back, left-right, and up-down directions. After the cutting direction guide 5 is installed, the light emission point of the guiding light of the cutting direction guide 5 is exactly on the same horizontal plane as the blade 4. Since the rotation of the cutting direction guide 5 in this embodiment is limited only by friction, when the guiding light emitted by the cutting direction guide 5 does not coincide with the blade 4, it is only necessary to rotate the cutting direction guide 5 by hand to make the position of the guiding light coincide with the blade 4. Furthermore, in this embodiment, the light emission point of the front end of the cutting direction guide 5 is located inside the second opening 9. After installation, the operator can directly rotate the cutting direction guide 5 inside the second opening 9 to adjust the emission angle of the guiding light, thereby making the position of the guiding light coincide with the blade 4.

[0031] Furthermore, in this embodiment, the positioning protrusion includes a mounting groove 7-4-1 formed on the outside of the cylindrical housing 7-2 and surrounding the housing 7-2, and a limiting ring 7-4-2 fitted inside the mounting groove 7-4-1. The limiting ring 7-4-2 protrudes from the outer surface of the cylindrical housing 7-2. In this embodiment, the limiting ring 7-4-2 can be made of elastic rubber material. The limiting ring 7-4-2 fits onto the outside of the mounting groove 7-4-1 through elastic deformation, making it more convenient to install the limiting ring 7-4-2. At the same time, when the cutting direction guide 5 is positioned and installed by the shielding part 12, the shielding part 12 presses the limiting ring 7-4-2 made of elastic rubber material inward, so that the cutting direction guide 5 fits tightly with the shielding part 12. At the same time, the thickness of the limiting ring 7-4-2 can be slightly greater than the groove width of the mounting groove 7-4-1, so that the cutting direction guide 5 can be stably installed in the receiving cavity 7 of the auxiliary mounting part 6.

[0032] Furthermore, such as Figure 5As shown, in order to increase the ambient brightness when the electric cutter is in use, the accommodating cavity 7 in this embodiment includes a light source mounting cavity 7-5 located at the bottom of the accommodating cavity 7 and a guide mounting cavity 7-6 located outside the light source mounting cavity 7-5. The arc-shaped surface 7-1 is formed on the inner wall of the guide mounting cavity 7-6. Thus, in this embodiment, a light source can be installed in the light source mounting cavity 7-5, and the light from the light source can also be emitted from the second opening 9, thereby illuminating the front of the blade 4 to facilitate the cutting and observation of the blade 4.

[0033] Specifically, such as Figure 3 and 6 As shown, in this embodiment, a wiring hole 15 is opened on the positioning mounting groove 10 to connect the inner side of the frame 1. The inner end of the connecting part 6-1 is opened with a channel 16 corresponding to the wiring hole 15 and connected to accommodate the inner cavity 7. In this embodiment, the frame 1 is also provided with a control element for controlling the start and stop of the drive motor 2. After the cutting direction guide 5 and the light source are installed, they can be connected to the control element in the frame 1 through the channel 16 and the wiring hole 15 to control the start and stop of the light source of the cutting direction guide 5.
