Problems solved by technology

At present, the commonly used splicing joint method on the automatic winder is to untwist the two yarns first, and then twist the two yarns to twist them together, because the two yarns are not completely entangled after untwisting and twisting Tight, especially the fiber at the end of the joint is entangled on the surface of the yarn with which it is jointed, and it is not effectively held, resulting in the end fiber not being fully involved in the yarn body, and it is easy to break when weaving

Embodiment 1

[0032] This embodiment provides a yarn joint bonding device.

[0033] A yarn splice bonding device, see figure 1 and figure 2 As shown, it includes a stocker 1, a heating and heat preservation part 2, a material extrusion part 3, a switch part, a positioning part and an induction part. The positioning part has a positioning groove 6 for the yarn to pass through, and the material extrusion part 3 is connected to the storage container 1, the sensing part is connected to the switch part, and the sensing part is an inductor; the switch part is a movable partition 4, and the movable partition 4 is slidably connected to the storage The feeder 1 is used to open or close the second opening. When the movable partition 4 is closed, see figure 1 shown; when the movable partition 4 is opened, see figure 2 shown.

[0034] The positioning component is connected to the stocker 1, and the positioning component has a plurality of channels 5, and the openings at both ends of the channel ...

Embodiment 2

[0040] This embodiment provides a method for using the yarn joint bonding device.

[0041] A method for using a yarn joint bonding device, comprising the steps of:

[0042] see image 3 As shown, the yarn is placed in the positioning groove 6 of the positioning part, the yarn advances at a certain speed, and when the yarn is not broken without jointing, the material extruding part 3 and the movable partition 4 are in the initial position;

[0043]When the sensing part receives the yarn knotting action signal, the switch part is turned on, and the multiple channels 5 on the positioning part are opened, the material extruding part 3 squeezes the stocker 1, and the hot melt adhesive in the stocker 1 passes through The channel 5 enters the yarn in the positioning groove 6, and the hot melt glue is sprayed onto the yarn joint and then cross-linked at normal temperature to make the yarn joint bonded, and the high temperature and sizing process in the subsequent dyeing and sizing pr...

Embodiment 3

[0051] This embodiment provides a method for using the yarn joint bonding device.

[0052] see image 3 As shown, in this embodiment, the second opening area of ​​the channel 5 on the positioning groove 6 in the yarn joint bonding device is 3mm 2 The distance between each adjacent channel 5 is 5 mm. When the yarn is not broken and does not need to be knotted, the heating and insulating part 2 outside the stocker 1 is heated and kept warm at a temperature of 100 ° C.

[0053] After the yarn breaks, the automatic knotting of the winding machine triggers the movable partition 4 in the yarn joint bonding device to be pulled out upwards, the channel 5 is opened, the positioning groove 6 determines the position of the joint, and the material extrusion part 3 starts to work at the same time. Through the channel 5, the hot melt adhesive is evenly distributed on the joints of the yarns, and the hot melt adhesive is quickly cross-linked at room temperature, so that the bonding between ...

Abstract

The invention discloses a yarn joint bonding device and a bonding method. The yarn joint bonding device includes a stocker, a heating and heat preservation part, a material extruding part, a switch part, a positioning part and an induction part. The material extruding part is connected to the stocker, and the heating and heat preservation part is sleeved On the outside of the stocker, the sensing part is connected to the switch part; the positioning part is connected to the stocker, and the positioning part has a positioning slot for yarn passing through, and the positioning part has multiple One end of the channel is opened on the inner wall of the positioning groove, the other end is opened on the storage container, and the switch component is connected to the storage container to open or close the channel. The yarn joint bonding device involved in the invention can improve the adhesive force at the yarn joint, is not easy to break at the yarn joint, has a simple structure, and can be operated automatically.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a yarn joint bonding device and bonding method. Background technique [0002] Winding is an essential process in the spinning process. At present, the commonly used splicing joint method on the automatic winder is to untwist the two yarns first, and then twist the two yarns to twist them together, because the two yarns are not completely entangled after untwisting and twisting Tightness, especially the fiber at the end of the joint is entangled on the surface of the yarn that is jointed with it, and it is not effectively held, which leads to the incomplete involvement of the end fiber in the yarn body, and it is easy to break when weaving. [0003] In the production and processing process of the actual loom, when the yarn with the joint is used as the warp yarn, due to the joint action of the tension of the loom, the friction force of the heald frame and the friction force of t...
