Description

TECHNICAL FIELD

[0001] The application relates to the technical field of sewing machines, in particular to a seamless knitted underpants sewing machine. BACKGROUND

[0002] The sewing machine is a kind of machine mainly used for sewing various fabrics and products, such as cotton, hemp, silk, wool and synthetic fiber fabric products.

[0003] In the related art, reference can be made to Chinese Invention Patent No. CN108884619A, which discloses a sewing machine having a sewing needle with a needle hole for inserting an upper thread therethrough; a shuttle having a tip that entangles the upper thread by capturing the upper thread to entangle the upper thread and a lower thread; a thread lifter having a small hole for inserting the upper thread therethrough, the small hole rising from a lower dead point to an upper dead point, thereby lifting the upper thread from a sewn object as a sewing object; a middle presser foot preventing the sewn object from being lifted; and a driving source driving the middle presser foot to stop at a constant height during the period of the action of the thread lifter and the rising of the small hole after the capturing of the shuttle on the upper thread is released.

[0004] However, the above-mentioned sewing machine generates a large amount of heat in the machine body after a long time of work, and the overheating of the machine body of the sewing machine easily leads to the damage of the internal working components of the sewing machine, thereby adversely affecting the sewing effect. CONTENT OF THE UTILITY MODEL

[0005] In order to reduce the heat of the machine body of the sewing machine itself after a long time of work, the application provides a seamless knitted underpants sewing machine.

[0006] The application provides a seamless knitted underpants sewing machine, which adopts the following technical scheme:

[0007] A seamless knitted underpants sewing machine, comprising a rack and a sewing machine body arranged on the rack, wherein a cooling mechanism for cooling the sewing machine body is arranged on the rack, and the cooling mechanism comprises:

[0008] A cooling plate head is arranged on the rack and abuts against the outer side wall of the sewing machine;

[0009] A cooling plate shell is arranged on the cooling plate head, and a sealed cooling cavity is formed between the cooling plate shell and the cooling plate head;

[0010] A cooling water tank is arranged on the rack, and the cooling water tank stores cooling liquid inside;

[0011] An outlet pipe and a return pipe are in communication with the cooling cavity and the cooling water tank, and a water pump is arranged on the outlet pipe;

[0012] The heat dissipation assembly is arranged on the rack and used for dissipating heat of the cooling liquid in the cooling water tank.

[0013] By adopting the above technical scheme, the cooling plate head is attached to the outer side wall of the sewing machine body, then the water pump is started to draw the cooling liquid into the outlet pipe, and the outlet pipe guides the cooling liquid into the cooling chamber formed by the cooling plate shell and the cooling plate head, thereby cooling the outer side wall of the sewing machine body, reducing the probability of overheating of the sewing machine body after long-time work; the cooling liquid after heat exchange with the outer side wall of the sewing machine body is guided into the cooling water tank by the return pipe, and is cooled by the heat dissipation assembly, thereby enabling the cooling liquid to be recycled.

[0014] Optionally, the heat dissipation assembly comprises:

[0015] The heat dissipation fan is rotationally arranged on the rack and electrically connected with the power supply of the sewing machine, and the heat dissipation fan blows air on the cooling water tank.

[0016] The heat dissipation thin pipes are arranged in the cooling water tank, and the cooling liquid entering the cooling water tank is uniformly distributed in the heat dissipation thin pipes.

[0017] By adopting the above technical scheme, the heat dissipation thin pipes are arranged in the cooling water tank, and the cooling liquid entering the cooling water tank is separated by the heat dissipation thin pipes, thereby increasing the heat dissipation area of the cooling liquid, and the heat dissipation fan blows air on the cooling water tank, thereby greatly improving the heat dissipation effect of the cooling liquid in the cooling water tank and completing the heat dissipation work of the cooling liquid.

[0018] Optionally, the cooling plate head is made of red copper material, the cooling plate shell is made of transparent acrylic material, the cooling plate head is provided with a connecting assembly, and the cooling plate head is detachably connected to the sewing machine body through the connecting assembly.

[0019] In the thermal conductivity coefficient of metal materials at 20℃, the thermal conductivity coefficient of pure copper is 398W / (m·K), which is only second to the thermal conductivity coefficient of silver, which is 427W / (m·K), and the cost of copper is much lower than that of silver, and the hardness of silver is too soft to cause deformation.

[0020] By adopting the above technical solution, using copper as the material for the cooling plate head ensures good heat conduction between the cooling plate head and the sewing machine body while keeping costs low, making it suitable for mass production. Using acrylic material for the cooling plate shell ensures its hardness and strength while significantly reducing its weight, making the cooling mechanism lighter and easier to move and transport. Furthermore, the transparent acrylic material allows workers to directly observe the coolant's operation within the cooling chamber, facilitating timely repairs in case of cooling mechanism malfunctions. Adding connecting components to the cooling plate head allows for easy replacement of the cooling plate head on the sewing machine body, and the cooling plate head can be used on different sewing machine bodies, expanding the applicability of the cooling mechanism.

[0021] Optionally, the connection component includes:

[0022] A first connecting plate and a second connecting plate, both of which are vertically slidably mounted on the cooling plate head;

[0023] The first connecting bolt and the second connecting bolt are both threaded onto the cooling plate head and pass through the first connecting plate and the second connecting plate respectively. The heads of the first connecting bolt and the second connecting bolt are respectively pressed against the first connecting plate and the second connecting plate. The first connecting plate and the second connecting plate clamp the sewing machine body under the action of the first connecting bolt and the second connecting bolt.

[0024] By adopting the above technical solution, loosening the first connecting bolt and the second connecting bolt allows the first connecting plate and the second connecting plate to move closer to or further apart from each other, thereby disassembling and fixing the cooling plate head to the sewing machine body. When the cooling plate head needs to be fixed to the sewing machine body, tightening the first connecting bolt and the second connecting bolt causes the heads of the first connecting bolt and the second connecting bolt to press against the first connecting plate and the second connecting plate respectively, thereby driving the first connecting plate and the second connecting plate to clamp the sewing machine body, thus completing the work of fixing the cooling plate head to the sewing machine body.

[0025] Optionally, two sliding plates are horizontally slidably disposed at the top and bottom of the cooling plate head, respectively, and the first connecting plate and the second connecting plate are respectively disposed on the two sliding plates. The cooling plate head is provided with a fixing component for fixing the position of the sliding plates.

[0026] By adopting the above technical solution, two sliding plates are horizontally slidably installed at the top and bottom of the cooling plate head, respectively. By unlocking the fixing components, the position of the sliding plates can be adjusted, thereby adjusting the relative position between the first connecting plate and the second connecting plate and the cooling plate head. This facilitates the connection between the cooling plate head and sewing machine bodies of different shapes, expanding the adaptability of the cooling plate head during installation.

[0027] Optionally, the fixing component includes:

[0028] The fixed block has a horizontal sliding groove on its cooling plate head, and the fixed block is slidably disposed in the sliding groove, and the sliding plate is disposed on the fixed block;

[0029] A fixed rod is provided, and a vertical moving groove is provided on the fixed block. The fixed rod is vertically slidably disposed on the moving groove.

[0030] A fixed spring is provided on the bottom wall of the sliding groove and connected to a fixed rod. Under the action of the fixed spring, the fixed rod extends out of the sliding groove and abuts against the inner wall of the sliding groove.

[0031] A compression component, which is mounted on a fixed block and is used to drive the fixed spring to compress.

[0032] By adopting the above technical solution, the compression component drives the fixed spring to compress. The compression of the fixed spring causes the fixed rod to move into the moving groove and disengage from the inner wall of the sliding groove. This allows the fixed block to be moved to adjust the position of the slide plate. After the adjustment is completed, the compression component is unlocked, and the fixed rod is pressed against the inner wall of the sliding groove under the action of the fixed spring, thereby limiting the position of the fixed block and completing the fixation of the slide plate position.

[0033] Optionally, the compression component is a compression rod, which is vertically slidably mounted on the fixed block and connected to the fixed rod.

[0034] By adopting the above technical solution, the compression rod is moved to drive the fixed rod to move. The fixed rod moves and compresses the fixed spring, so the fixed rod moves into the moving groove and disengages from the inner wall of the sliding groove. The fixed block can then be moved to adjust the position of the slide plate. After the adjustment is completed, the compression rod is released, and the fixed rod is pressed against the inner wall of the sliding groove under the action of the fixed spring, thereby limiting the position of the fixed block and completing the fixation of the slide plate position.

[0035] Optionally, the surface of the cooling plate head is nickel-plated.

[0036] By adopting the above technical solution, since copper itself has poor oxidation resistance, the surface of the cooling plate head made of copper will turn black after a long period of use and is prone to many scratches, which is very unsightly. Therefore, nickel plating is applied to the surface of the cooling plate head to make the cooling plate bright and beautiful and improve the strength of the plate.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. By attaching the cooling plate head tightly to the outer wall of the sewing machine body, the water pump is started to draw coolant into the outlet pipe, which then guides the coolant into the cooling chamber formed by the cooling plate shell and the cooling plate head. This cools the outer wall of the sewing machine body, reducing the probability of the machine body overheating after prolonged operation. After heat exchange with the outer wall of the sewing machine body, the coolant returns to the cooling water tank through the return pipe and is cooled by the heat dissipation components, thus allowing the coolant to be recycled.

[0039] 2. By installing multiple heat dissipation tubes inside the cooling water tank, the coolant entering the tank is separated by these tubes, thereby increasing the heat dissipation area of ​​the coolant. At the same time, the cooling fan blows air onto the cooling water tank, greatly improving the heat dissipation effect of the coolant within the tank and completing the heat dissipation work of the coolant.

[0040] 3. By plating nickel on the surface of the cooling plate head, the cooling plate becomes bright and beautiful, and the plate strength is improved. Attached Figure Description
