Description

Technical Field

[0001] This utility model relates to the technical field of twisting machines, specifically a high-performance twisting machine that facilitates heat dissipation. Background Technology

[0002] A doubling twister is a twisting device, also known as a doubling machine. It mainly consists of a power unit, a doubling unit, and a transmission unit. It can twist and bond two or more single yarns into a ply, thereby enhancing the performance of the original yarn.

[0003] A search revealed that prior art, publication number CN214032792U, discloses a high-performance twisting machine with convenient heat dissipation. The machine includes a twisting machine body, a control box fixedly mounted on the left side of the body, a twisting shaft rotatably mounted on the upper part of the body, multiple yarn winding rollers detachably mounted on the twisting shaft, and a linear speed motor powered by the left end of the twisting shaft extending into the control box. A guide shaft rotatably mounted below the twisting shaft is located inside the machine body. During operation, this invention achieves precise heat dissipation for each spindle motor through horizontal heat pipes, precise heat dissipation for the overfeed motor through short heat pipes, precise heat dissipation for the linear speed motor through long heat pipes, and precise heat dissipation for each guide roller and each yarn winding roller through a cooling fan. This enables overall heat dissipation of the twisting machine, and allows for faster and better heat dissipation.

[0004] However, the following drawbacks still exist in this device and existing technology:

[0005] Existing twisting machines dissipate heat by exhausting cold air to the linear speed motor and overfeed motor, and to the transmission box. However, there is no heat dissipation structure at the contact points between the yarn and the conductor structure. This cannot effectively release the heat generated by friction on the conductor structure, and the resulting increase in conductor structure temperature will affect the yarn, reduce the heat dissipation efficiency of the twisting machine, and fail to meet the usage requirements. Utility Model Content

[0006] The purpose of this invention is to provide a high-performance twisting machine that facilitates heat dissipation.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A high-performance twisting machine with convenient heat dissipation includes a twisting machine body. The twisting machine body has an internal mounting cavity, inside which are housed a linear speed motor, an overfeed motor, and a spindle motor. These motors are connected to the twisting machine body via screws. A bobbin seat is located at the bottom of the twisting machine body and is rotatably connected to it. The lower end of the bobbin seat is connected to the output end of the spindle motor. A spindle tube is located above the bobbin seat and is inserted into the bobbin seat. A twisting spool and a guide shaft are located above the spindle tube and are rotatably connected to the twisting machine body. One end of each twisting spool and guide shaft is connected to the linear speed motor. The machine is connected to the output end of the overfeed motor. A yarn winding roller is provided on the twisting shaft, and a first guide roller is provided on the guide shaft. An air jet disc is provided on one side of each of the linear speed motor, overfeed motor, and spindle motor. A blower and a cooling box are provided at the bottom of the mounting cavity, and the blower and cooling box are connected to the main body of the twisting machine by screws. The blower and cooling box are connected in communication. A mounting frame is provided on one side of the first guide roller, and the mounting frame is connected to the main body of the twisting machine by screws. A flow cavity is provided inside the mounting frame, and a nozzle is provided on the inner side of the mounting frame. The nozzle is integrated with the mounting frame. A connecting pipe is provided between the cooling box, the mounting frame, and the air jet disc.

[0009] By adopting the above technical solution, the blower draws air and injects it into the cooling box equipment. The cooling box equipment cools the air and lowers its temperature. The cooled air is then sprayed through the connecting pipe and jet disc onto the linear speed motor, overfeed motor, and spindle motor. The cold air is used to cool the linear speed motor, overfeed motor, and spindle motor. The cooled air is then sprayed through the connecting pipe and nozzle onto the contact parts between the yarn and the conductor structure to cool the conductor structure and prevent frictional heating of the conductor structure from affecting the yarn.

[0010] Furthermore, a connecting frame is provided on one side below the guide shaft, and the connecting frame is connected to the main body of the twisting machine by screws. A second guide roller is provided on one side of the connecting frame. There are two second guide rollers, and the second guide rollers are rotatably connected to the connecting frame.

[0011] By adopting the above technical solution, the two second guide rollers and the first guide roller form a triangular structure, which can better guide the conveyed yarn.

[0012] Furthermore, a gas ring guide is provided below the connecting frame, and the gas ring guide is connected to the main body of the doubling machine by screws.

[0013] By adopting the above technical solution, the yarn passes through the air ring guide, which guides the pulled-out yarn, making the yarn move vertically upward, avoiding tension fluctuations during yarn winding, and improving the yarn forming quality.

[0014] Furthermore, a connecting rod is provided on one side below the twisting shaft, and the connecting rod is telescopically slidably connected to the main body of the twisting machine. A guide ring is provided above the connecting rod, and the guide ring is fixedly connected to the connecting rod. The guide ring is correspondingly arranged with the yarn winding roller.

[0015] By adopting the above technical solution, the yarn passes through the guide ring, which guides the wound yarn. The connecting rod moves horizontally back and forth, and as the connecting rod moves, it drives the guide ring to move synchronously, which facilitates the even winding of the yarn onto the yarn roll.

[0016] Furthermore, a metal mesh plate is provided on one side of the mounting cavity, and the metal mesh plate is connected to the body of the twisting machine by screws.

[0017] By adopting the above technical solution, the air in the installation cavity can be discharged through the metal mesh plate, and the heat released by the linear speed motor, overfeed motor and spindle motor can be transferred, thus preventing heat from accumulating in the installation cavity and being unable to be discharged.

[0018] Furthermore, an air inlet is provided on one side of the main body of the twisting machine, and the air inlet is located on the side of the blower. A filter screen is provided inside the air inlet, and the filter screen is integrated with the main body of the twisting machine.

[0019] By adopting the above technical solution, the filter screen filters the extracted air, preventing dust and lint from being sucked in and causing blockage of the jet structure, thus ensuring the stable use of the heat dissipation structure.

[0020] In summary, the beneficial technical effects of this utility model are as follows:

[0021] 1. The system employs a mounting frame, blower, cooling box, connecting pipe, nozzle, and jet disc. The blower draws air and injects it into the cooling box, where it is cooled to lower the air temperature. The cooled air is then sprayed through the connecting pipe and jet disc onto the linear speed motor, overfeed motor, and spindle motor to further cool them. The cooled air is then sprayed through the connecting pipe and nozzle onto the contact area between the yarn and conductor structure to cool the conductor structure, preventing friction and heat generation from affecting the yarn and improving heat dissipation efficiency.

[0022] 2. A metal mesh plate is used, which can expel air from the mounting cavity and transfer the heat released by the linear speed motor, overfeed motor and spindle motor, preventing heat from accumulating in the mounting cavity and improving heat dissipation efficiency.
