[0056] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0057] In the related art, a one-way circulating water flow is generally used to cool the cooling plate, and then the cable tie is cooled through the cooling plate. However, when the overall equipment has been running for a long time, the temperature of the water outlet side of the cooling plate will be significantly higher than the temperature of the water inlet side, resulting in uneven cooling of the cable tie near the water outlet side and the water inlet side, different forming speeds, and large defects in the shape of the cable tie.

[0058] To solve the above problems, refer to Figure 5 At least one embodiment provides a pipeline assembly, including: a main cooling pipe 1, the axis of the main cooling pipe 1 is axially through-arranged so that cooling water can flow through the main cooling pipe 1, and thus the main cooling pipe 1 can be divided into a water inlet pipe 11 and a water outlet pipe 12 along both ends, and a water inlet connecting pipe 13 is provided on one side of the water inlet pipe 11, and a water outlet connecting pipe 14 is provided on one side of the water outlet pipe 12. Through the above arrangement, a hose can be connected to the water inlet connecting pipe 13, and then the other end of the hose can be connected to the water outlet connecting pipe 14, thereby forming a cooling cycle. The entire pipeline assembly is placed in a specific device, which can be used as a cooling cycle to cool molten materials, such as the original molten raw material of cable ties. At the same time, based on the above arrangement, refer to Figure 6There is a connecting groove 15 between the outlet pipe 12 and the inlet pipe 11, so that the outlet pipe 12 and the inlet pipe 11 are directly connected. Inside the main cooling pipe 1, after the cooling water enters from the inlet pipe 11, part of the cooling water enters the cooling cycle through the inlet connecting pipe 13, while the other part of the cooling water directly passes through the connecting groove and enters the outlet pipe 12, and mixes with the cooling water in the outlet pipe 12. Since the water in the outlet pipe 12 has a significantly higher temperature after a round of cooling cycle, the temperature of the entire cooling cycle on the side close to the outlet pipe 12 is significantly higher than that on the side of the inlet pipe 11. Therefore, through the above arrangement, the water in the inlet pipe 11 can be introduced into the outlet pipe 12 to achieve the effect of heat exchange, thereby reducing the temperature of the cooling water in the outlet pipe 12.

[0059] On the other hand, the cooling efficiency of the water outlet pipe 12 only by diversion is limited, and the cooling cycle is not directly cooled, and the cooling will still be uneven. In order to solve the above problems, in at least one embodiment, a floating member 2 is also slidably arranged in the connecting groove, and the floating member 2 is spaced apart from the bottom wall of the connecting groove 15. The main cooling pipe 1 is located in the connecting groove and radially penetrates to one side so that the floating member 2 can slide along the opening direction, and the floating member 2 has a first position and a second position along the sliding direction. In turn, the opening size between the connecting groove and the water inlet pipe 11 and the water outlet pipe 12 is controlled. Reference Figure 6 That is, when the floating member 2 is at the axial position closest to the main cooling pipe 1, the floating member 2 is at the first position, and the gap between the floating member 2 and the bottom wall of the connecting groove is the smallest. At this time, the cooling water enters the water inlet pipe 11 and then splits, with most of it entering the cooling cycle through the water inlet connecting pipe 13, and a small part entering the water outlet pipe 12 through the connecting groove. Figure 7When the floating member 2 slides outward along the opening direction, the floating member 2 is in the second position, and the gap distance between the floating member 2 and the bottom wall of the connecting groove 15 increases, thereby increasing the water flow through the connecting groove. Further, one side of the floating member 2 extends into the water inlet pipeline 11 and corresponds to the water inlet connecting pipe 13. Specifically, the floating member 2 also includes a closing plate 26, which is installed on the floating seat 23 and extends into the inside of the water inlet pipeline 11 and corresponds to the position of the water inlet connecting pipe 13. When the floating member 2 slides outward, the closing plate 26 also slides in the direction of the water inlet connecting pipe 13 synchronously, until the floating member 2 reaches the second position, the closing plate 26 closes the water inlet of the water inlet connecting pipe 13. At this time, the cooling water cannot enter the water inlet connecting pipe 13, but completely enters the water outlet pipeline 12 through the connecting groove, and enters the cooling cycle from the water outlet connecting pipe 14, and then flows in the inner direction of the cooling cycle, that is, from the water outlet connecting pipe 14 to the water inlet connecting pipe 13. Thus, by making the cooling water flow in the reverse direction, the cooling water can fully cool the cooling cycle near the water outlet pipe 12, and the cooling water repeatedly switches between forward and reverse flow in the cooling cycle to ensure uniform temperature distribution in the cooling cycle. Figure 8 and Fig. 9 The floating member 2 has a diversion inlet 21 and a diversion outlet 22 which are connected to each other. The diversion inlet 21 corresponds to the water inlet connecting pipe 13, and the diversion outlet 22 corresponds to the water outlet pipeline 12. Figure 7 When the floating member 2 is in the second position, the cooling water enters the water outlet connecting pipe 14 through the connecting groove, and after returning to the water inlet connecting pipe 13, enters the floating member 2 from the diversion inlet 21, flows inside the floating member 2 to the diversion outlet 22, and returns to the water outlet pipeline 12 through the diversion outlet 22 and is discharged.

[0060] refer to Figure 8 and Fig. 9 The floating member 2 includes an integrally arranged floating seat 23 and a guide ring 24. The floating seat 23 is adapted to the opening size of one side of the connecting groove, so that the floating seat 23 is limited at the opening of the connecting groove and can slide along the connecting groove. The guide ring 24 is arranged in an annular shape, surrounding the outer side of the main cooling pipe 1. A guide pipeline 231 is provided inside the floating seat 23, and an annular pipeline 241 is provided inside the guide ring 24. The guide pipeline 231 is connected to the annular pipeline 241, and the guide pipeline 231 is connected to the guide inlet 21, and the annular pipeline 241 is connected to the guide outlet 22. So that after the cooling water enters the guide pipeline 231 from the guide inlet 21, it can then enter the annular pipeline 241 and reach the guide outlet 22 from the annular pipeline 241.

[0061] In addition, in order to allow the cooling water in the annular pipe to enter the water outlet pipe 12, the guide ring 24 is provided with an insert block 25, and a matching groove 121 is opened on one side of the water outlet pipe 12. The insert block 25 is inserted into the matching groove 121, and the guide outlet 22 is located at the end of the insert block 25 away from the guide ring 24. Figure 6 When the floating member 2 is located at the first position, the diversion outlet 22 is contracted in the matching groove 121, and the matching groove 121 closes the diversion outlet 22; Figure 7 When the floating member 2 is located at the second position, the diversion outlet 22 is inserted into the water outlet pipeline 12 so that the annular pipeline 241 is connected to the water outlet pipeline 12.

[0062] In order to control the connection and disconnection between the water inlet connecting pipe 13 and the floating seat 23, in some embodiments, reference Figure 5 A transition pipeline 131 is provided on the side of the water inlet connecting pipe 13 facing the floating seat 23, and the transition pipeline 131 corresponds to the flow guiding pipeline 231. With the above arrangement, when the floating member 2 is located at the first working position, the transition pipeline 131 and the flow guiding pipeline 231 are arranged in a staggered manner, and the cooling water in the water inlet connecting pipe 13 enters the cooling cycle. Figure 7 When the floating member 2 is located at the second position, the transition pipeline 131 is aligned with the guide pipeline 231 , and the cooling water in the water inlet connecting pipe 13 enters the guide pipeline 231 through the transition pipeline 131 .

As an option, a shallow groove surrounding the water cooling plate 3 is opened on the outer wall of the water cooling plate 3, and the outlet of the extruder head 6 is directly opposite to the shallow groove. The extruder head 6 can be connected to other raw material conveying equipment, and the molten raw material of the cable tie is conveyed into the extruder head 6, and the extruder head 6 sprays the molten raw material into the shallow groove, cools in the shallow groove, and forms a strip. An electrostatic generator 7 is arranged between the extruder head 6 and the water cooling plate 3, and the electrostatic generator 7 can ensure that the molten raw material sprayed by the extruder head 6 is attached to the shallow groove under the action of static electricity.

The water inlet and the water outlet of the spiral cooling groove 31 can be connected to the water inlet connecting pipe 13 and the water outlet connecting pipe 14 respectively through a hose, so that the cooling water can repeatedly flow forward and reverse in the spiral cooling groove 31.

[0065] refer to Figure 3 In some embodiments, a driving motor 43 and a reducer 44 are installed on the equipment rack 4. The reducer 44 is installed at the movable end of the driving motor 43, and the output end of the reducer 44 is connected to the main cooling pipe 1. The equipment rack 4 can output torque through the driving motor 43, and transmit the torque to the main cooling pipe 1 through the reducer 44, so that the main cooling pipe 1 rotates. On the other hand, the ends of the water inlet pipe 11 and the water outlet pipe 12 are both installed with a rotary joint 5 for connecting the water supply pipe, and do not need to rotate with the main cooling pipe 1.
