Description

Technical Field

[0001] This utility model relates to a self-weighting fabric cutting machine, belonging to the field of garment fabric cutting equipment. Background Technology

[0002] Electric scissors are handheld power tools that use an electric motor to drive the working head through a transmission mechanism for cutting operations. They mainly consist of an electric motor, a gearbox, an eccentric shaft-linkage mechanism, a switch, a battery, and blades. In garment production lines, they are used to cut garment pieces into front pieces, back pieces, sleeve pieces, etc. For example, large cutting machines are not flexible enough for small areas such as collars and cuffs, so electric fabric cutting machines are used.

[0003] However, in practice, when the fabric is too thin and has many layers, lightweight electric scissors generally lack sufficient power. During the cutting process, if the fabric layers are not completely cut, they will shift, and the electric scissors will also shift due to the movement of the fabric. Secondly, existing electric scissors have a high center of gravity, and when cutting thick fabrics, they lack power and are unstable, relying entirely on manual handling.

[0004] Therefore, this utility model provides a self-weighting fabric cutting machine with a counterweight function. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a self-weighting fabric cutting machine with a counterweight function.

[0006] This utility model is implemented as follows:

[0007] A self-weighted fabric cutting machine includes a cutting blade, a coupling, a motor, a metal shaft, and a counterweight. The motor is enclosed in a first housing, and the output end of the motor is mechanically connected to the center position of the cutting blade via the coupling.

[0008] The top surface of the first housing is detachably and fixedly connected to the head end of the metal shaft, and one or more counterweights are detachably and fixedly connected to the metal shaft.

[0009] As a further improvement, the present invention also includes a controller and a battery compartment. The controller is vertically fixed to the tail end of the metal shaft by a bracket. The battery compartment is detachably fixed to the controller and is electrically connected to the controller.

[0010] As a further improvement, the controller and motor are connected by signals.

[0011] As a further improvement, the cross-sectional shape of the counterweight is an incomplete circle.

[0012] As a further improvement, the arc length of the outer surface of the counterweight is one-half to four-fifths of the circumference of the circle in which it is located.

[0013] As a further improvement, the inner surface of the counterweight is provided with a magnetic sheet.

[0014] As a further improvement, the battery compartment includes a second outer shell, metal contacts, a cap, and a battery; the number of metal contacts is distributed on the end face of the controller that contacts the second outer shell, the second outer shell contains one or more batteries, and the other end of the second outer shell is sealed with a cap so that the battery contacts the metal contacts to supply power to the controller.

[0015] As a further improvement, the metal contact can be circular or sheet-like in shape.

[0016] The beneficial effects of this utility model are:

[0017] The motor of this invention is located at the front, on one side of the cutting blade, which lowers the center of gravity of the equipment structure. During the production stage, different numbers of counterweights are installed according to the actual fabric classification, such as thick fabric, thin fabric, and medium-thickness fabric. Fewer counterweights are more suitable for thick fabrics, while more counterweights are more suitable for thin fabrics. This increases the weight of the equipment, lowers the center of gravity, and improves the stability of the equipment. For operators with less strength, this also improves the stability during the cutting process.

[0018] The counterweight of this utility model has a built-in limiting structure, making it easy to install and disassemble. It can adjust the position of the counterweight on the metal shaft and can also stack counterweights on the metal shaft. During later maintenance, the third outer shell of the equipment can be disassembled to readjust the number of counterweights, or it can be left unadjusted, offering high flexibility.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] Reference Figures 1 to 5 As shown, this embodiment provides a specific implementation of a self-weighting fabric cutting machine, including a cutting blade 10, a coupling 20, a motor 40, a metal shaft 50, and a counterweight 60. The motor 40 is enclosed in a first housing, and the output end of the motor 40 is mechanically connected to the center position of the cutting blade 10 through the coupling 20.

[0029] The top surface of the first housing is detachably and fixedly connected to the head end of the metal shaft 50, and one or more counterweights 60 are detachably and fixedly connected to the metal shaft 50.

[0030] The present invention also includes a controller 70 and a battery compartment 80. The controller 70 is vertically fixed to the tail end of the metal shaft 50 by a bracket. The battery compartment 80 is detachably fixed to the controller 70 and is electrically connected to the controller 70.

[0031] Furthermore, the controller 70 and the motor 40 are connected by signals.

[0032] Furthermore, the motor 40 can also be selected with a power between 100W and 1000W, and is small in size, light in weight, and has high torque.

[0033] The present invention also includes a third housing 30, which includes a handle for shielding the controller 70 and the battery compartment 80, and the handle is also provided with a switch for controlling the operation of the controller 70. The third housing 30 also includes a cover for shielding the cutting blade 10, the coupling 20, the motor 40, the metal shaft 50, and the counterweight 60.

[0034] In the above technical solution, the motor 40 of this utility model is positioned at the front and located on one side of the cutting blade 10, which lowers the center of gravity of the equipment structure. In the production stage, according to the actual fabric classification, such as thick fabric, thin fabric, and moderately thick fabric, different numbers of counterweights 60 are selected for installation. Fewer counterweights are more suitable for thick fabrics, while more counterweights 60 are more suitable for thin fabrics, thereby increasing the weight of the equipment, lowering the center of gravity, and improving the stability of the equipment. For operators with less strength, this also improves the stability during the cutting process.

[0035] In one specific embodiment, the cross-sectional shape of the counterweight 60 is an incomplete circle.

[0036] Furthermore, the arc length of the outer surface of the counterweight 60 is one-half to four-fifths of the circumference of the circle in which it is located.

[0037] Furthermore, the inner surface of the counterweight 60 is provided with a magnetic sheet 601.

[0038] In this embodiment, combined with Figures 3 to 4 As shown, the counterweight 60 of this utility model has a built-in limiting structure, making it easy to install and disassemble. It can adjust the position of the counterweight 60 on the metal shaft 50, and can also stack the counterweight 60 on the metal shaft 50. During later maintenance, the third outer shell 30 of the equipment can be disassembled to readjust the number of counterweights 60, or it can be left unadjusted, which is highly flexible.

[0039] In other embodiments, the material of the counterweight 60 includes, but is not limited to, barite, lead, ductile iron, malleable cast iron, ultra-low carbon stainless steel, aluminum-copper alloy, aluminum-silicon alloy, aluminum-magnesium alloy, titanium-based alloy, and nickel-based alloy, etc., and the counterweight 60 is directly machined using cast iron technology, which is simple and easy to operate.

[0040] In this embodiment, the battery compartment 80 includes a second outer shell 801, metal contacts 802, a cylindrical cover 803, and a battery 804. Several metal contacts 802 are distributed on the end face of the controller 70 that contacts the second outer shell 801. The second outer shell 801 contains one or more batteries 804, and the other end of the second outer shell 801 is sealed with a cylindrical cover 803. This allows the battery 804 to contact the metal contacts 802 to supply power to the controller 70, and also allows the battery 804 to be connected to the motor 40 via wires.

[0041] Furthermore, the metal contact 802 is circular or sheet-like in shape.

[0042] The above technical solution describes in detail the structure and principle of the battery compartment 80, which enables the device battery 804 to supply power to the controller 70 and the motor 40, ensuring the normal operation of the device.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
