[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] This utility model discloses a three-color ribbon cable extrusion machine, according to the attached... Figure 1-7 As shown, the device includes a feeding unit 1 and an extrusion unit 2. The extrusion unit 2 is connected to the outside of the feeding unit 1. The feeding unit 1 includes a housing 11 and a drive shaft 12. A feeding pipe 112 is inserted into the inside of the housing 11, and three sets of feeding pipes 112 are provided. The drive shaft 12 is inserted into the inside of the feeding pipe 112. The extrusion unit 2 includes an extrusion head 21 and a connector 22. A wire guide tube 213 is provided inside the extrusion head 21, and three sets of wire guide tubes 213 are provided. A discharge pipe 214 is connected to the outside of the extrusion head 21, and a fitting opening 215 is provided inside the discharge pipe 214. The connector 22 is connected to the outside of the extrusion head 21 and is used to connect to the feeding unit 1.

[0035] The simultaneous extrusion of three-color wires shortens the production cycle and significantly improves efficiency compared to the traditional step-by-step bonding process. The bonding port 215 inside the discharge tube 214 allows adjacent wires to adhere better during the extrusion process, preventing separation. The cooperation of the drive wheel 122, linkage wheel 123, and drive belt 124 ensures the synchronous rotation of the three sets of drive shafts 12, improving the stability of equipment operation and thus increasing production efficiency.

[0036] According to the appendix Figure 1-2 As shown, further, a hopper 111 is connected to the top of the housing 11, and the hopper 111 is connected to the conveying pipe 112.

[0037] According to the appendix Figure 1-4 As shown, a first cavity 113 is further provided on the inner side of the housing 11. The first cavity 113 is sleeved on the outside of the conveying pipe 112, and an electric heating wire 114 is inserted into the inner side of the first cavity 113.

[0038] According to the appendix Figure 1-4 As shown, a spiral pusher plate 121 is connected to the outside of the drive shaft 12. The spiral pusher plate 121 is used to push the raw material to move inside the conveying pipe 112.

[0039] According to the appendix Figure 1-3 As shown, specifically disclosed, one set of transmission shaft 12 has a transmission wheel 122 sleeved on its outer side, and the other two sets of transmission shaft 12 have linkage wheels 123 sleeved on their outer sides. The transmission wheel 122 has a transmission belt 124 sleeved on its outer side, and the transmission belt 124 has two sets respectively sleeved on the outer side of the two sets of linkage wheels 123.

[0040] According to the appendix Figure 1-7 As shown, it is particularly important to emphasize that a partition plate 211 is provided on the inner side of the extrusion head 21. The partition plate 211 divides the internal space of the extrusion head 21 to form a second cavity 212, which is sleeved on the outside of the conduit 213.

[0041] According to the appendix Figure 1-7 As shown, it is particularly important to emphasize that the inner side of the discharge pipe 214 is provided with a fitting opening 215, which allows adjacent wires to be bonded together.

[0042] According to the appendix Figure 1-7 As shown, the connector 22 is sleeved on the outside of the drive shaft 12, and a connecting square tube 221 is connected to the outside of the connector 22. The connecting square tube 221 is connected to the second cavity 212 inside the connector 22.

[0043] Working Principle: During operation, three different colored raw materials are added from the three hoppers 111 into their corresponding feed pipes 112. The drive unit is activated, rotating the drive shaft 12 with the drive wheel 122. Through the transmission belt 124, the other two sets of drive shafts 12 with linkage wheels 123 rotate synchronously. As the drive shaft 12 rotates, the spiral pusher plate 121 pushes the raw material forward within the feed pipe 112. Simultaneously, the electric heating wire 114 heats the raw material within the feed pipe 112, maintaining its appropriate fluidity. The raw material enters the second cavity 212 of the extruder head 21 through the connector 22 and the connecting square tube 221. It is then extruded through the threading tube 213 and wrapped around the outside of the wire, entering the inside of the discharge pipe 214. At this point, the uncooled and solidified adjacent wire sheaths adhere together through the bonding opening 215, forming a three-color ribbon cable.
