Description

Technical Field

[0001] The utility model relates to the technical field of polyester, in particular to an oiling mechanism for polyester DTY yarn. Background Art

[0002] DTY (Draw-Textured Yarn) is the finished product after continuous or simultaneous stretching on a texturing machine and texturing in a twister. Before texturing, the DTY yarn requires surface oiling to protect the yarn, improve its quality, and prevent breakage. The existing oiling mechanism consists of an oil supply tank and an oiling brush. Oil in the oil supply tank is delivered to the oiling brush via a pipe, which then applies the oil to the surface of the polyester DTY yarn.

[0003] Regarding the above-mentioned related technologies, the inventors found that the oiling brush includes an oiling brush handle and bristles installed on the oiling brush handle. The bristles are in contact with the polyester DTY yarn, thereby applying oil to the surface of the DTY yarn. However, the surface of the DTY yarn away from the bristles cannot be evenly covered with oil, thereby reducing the uniformity of oiling the polyester DTY yarn, that is, reducing the quality of the product. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide an oiling mechanism for polyester DTY yarns, which solves the problem of uneven oiling of polyester DTY yarns.

[0005] To solve the above technical problems, the present invention adopts a technical solution: to provide an oiling mechanism for polyester DTY yarn, comprising: an oil storage box with an open top, V-shaped guide roller assemblies connected to both ends of the oil storage box, an oil immersion roller assembly connected to the inner cavity of the oil storage box near the bottom, a V-shaped guide roller assembly provided on one side of the oil immersion roller assembly in the horizontal direction, and a support roller provided on the other side, a lifting oil squeezing roller assembly provided above the support roller, and both ends of the support roller passing through the side wall of the oil storage box and being rotatably connected thereto;

[0006] It also includes a lifting mechanism for driving the V-shaped guide roller assembly to move up and down.

[0007] By adopting the above technical solution, when in use, an appropriate amount of oil is injected into the oil storage box to adhere to the surface of the polyester DTY yarn. After the oiled polyester DTY yarn passes around the V-shaped guide roller assembly at one end of the oil storage box, the polyester DTY yarn passes under the V-shaped guide roller assembly and is wound around the V-shaped guide roller assembly. Next, the polyester DTY yarn passes under the oil-immersed roller assembly and is wound around the oil-immersed roller assembly. The surface of the polyester DTY yarn is adhered to a lot of oil. After passing the oil-immersed roller assembly, the polyester DTY yarn is wound around the supporting roller. The lifting oil squeezing roller assembly squeezes the polyester DTY yarn, thereby squeezing out excess oil on the polyester DTY yarn, thereby enhancing the polyester DTY yarn. The uniformity of oil adhesion on the surface of the TY yarn improves the quality of the product. The polyester DTY yarn with excess oil squeezed out passes around the V-shaped guide roller assembly at the other end of the oil tank and enters the next process. According to actual needs, the V-shaped guide roller assembly is driven downward by operating the lifting mechanism to increase the length of the polyester DTY yarn immersed in the oil. Under the condition that the transmission speed of the polyester DTY yarn remains unchanged, more oil can be adhered to the surface of the polyester DTY yarn. The lifting mechanism is operated to drive the V-shaped guide roller assembly to move upward, so that the length of the polyester DTY yarn immersed in the oil is reduced. Under the condition that the transmission speed of the polyester DTY yarn remains unchanged, less oil is adhered to the surface of the polyester DTY yarn.

[0008] In a preferred example, the present invention can be further configured as follows: the V-shaped guide roller assembly includes a V-shaped guide roller body and a first U-shaped seat rotatably connected to both ends thereof, and the first U-shaped seat is connected to the oil tank body.

[0009] By adopting the above technical solution, the polyester DTY yarn changes its transmission direction after being wound on the V-shaped guide roller body one, and the V-shaped guide roller body one plays a guiding role for the polyester DTY yarn.

[0010] In a preferred example, the present invention can be further configured as follows: the oil-immersed roller assembly includes a V-shaped guide roller body and a fixing seat rotatably connected to both ends thereof, and the fixing seat is connected to the inner wall of the oil container body.

[0011] By adopting the above technical solution, after the polyester DTY yarn is wound on the second V-shaped guide roller body, the polyester DTY yarn is immersed in the oil of the oil tank body, thereby achieving the purpose of oiling.

[0012] In a preferred example, the present invention can be further configured as follows: the V-shaped guide roller assembly includes a V-shaped guide roller body and a second U-shaped seat rotatably connected to both ends thereof.

[0013] By adopting the above technical solution, the polyester DTY yarn is wound on the V-shaped guide roller body, and the lifting mechanism drives the V-shaped guide roller assembly to rise and fall in the vertical direction, thereby adjusting the length of the polyester DTY yarn immersed in the oil.

[0014] In a preferred example, the present invention can be further configured as follows: the lifting oil squeezing roller assembly includes an oil squeezing roller, a third U-shaped seat and a U-shaped frame connected to the top of the oil storage box, the two ends of the oil squeezing roller are rotatably connected to the third U-shaped seat, and a telescopic drive mechanism for driving the third U-shaped seat to rise and fall is installed on the U-shaped frame, and the telescopic drive mechanism includes a first electric push rod installed on the U-shaped frame and a first guide rod component arranged on both sides of the first electric push rod, the protruding end of the first electric push rod is connected to the third U-shaped seat, and the lower end of the first guide rod component is connected to the third U-shaped seat.

[0015] By adopting the above technical solution, the telescopic rod of the first electric push rod extends and contracts, thereby adjusting the minimum gap between the oil squeezing drum and the supporting drum, that is, adjusting the oil content attached to the surface of the polyester DTY yarn.

[0016] In a preferred example, the present invention can be further configured as follows: the lifting mechanism includes a horizontal support plate, a second electric push rod is installed on the horizontal support plate, second guide rod components are respectively provided on both sides of the second electric push rod, the protruding end of the second electric push rod is connected to the V-shaped guide roller assembly, and the lower end of the second guide rod component is connected to the V-shaped guide roller assembly.

[0017] By adopting the above technical solution, the telescopic rod of the second electric push rod extends and contracts, thereby driving the V-shaped guide roller assembly to move in the vertical direction, that is, adjusting the length of the polyester DTY yarn immersed in the oil.

[0018] In summary, the present invention has at least one of the following beneficial technical effects:

[0019] 1. When the transmission speed of the polyester DTY yarn remains unchanged, the telescopic rod of the second electric push rod extends and retracts, thereby driving the V-shaped guide roller assembly to move in the vertical direction, that is, adjusting the length of the polyester DTY yarn immersed in the oil, and the amount of oil adhered to the polyester DTY yarn will change to a certain extent.

[0020] 2. The telescopic rod of the first electric push rod extends and retracts to adjust the minimum gap between the oil squeezing drum and the supporting drum, that is, to adjust the oil content attached to the surface of the polyester DTY yarn. BRIEF DESCRIPTION OF THE DRAWINGS
