Description

Technical Field

[0001] The invention relates to the technical field of pre-networking devices, in particular to a polyester POY pre-networking device. Background Art

[0002] In the process of producing polyester yarn, after the workers have carried out processes such as oiling the yarn bundles, they also need to carry out a networking process on the yarn bundles to enhance the cohesion and strength of the yarn bundles. The pre-networking device is one of the important pre-networking devices in the polyester yarn networking processing.

[0003] When the existing pre-networking device is networking the polyester yarn, it is difficult to spray the oil mist evenly on the polyester yarn. The polyester yarn cannot be scraped before entering the nozzle chip. After the polyester yarn passes through the nozzle chip, it is also impossible to scrape off the excessive oil mist adhering to the surface of the polyester yarn, and multiple polyester yarns cannot be squeezed to make the multiple polyester yarns more tightly mixed. For this reason, we propose a polyester POY pre-networking device. Summary of the invention

[0004] The purpose of the present invention is to provide a polyester POY pre-network device to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions: a polyester POY pre-network device, comprising a base, a nozzle chip is fixedly mounted on the base, the hole on the nozzle chip is a circular hole, a compressed air connector is fixedly mounted on the side of the base, the compressed air connector is used to provide airflow to the nozzle chip, an oil nozzle is installed on the rear side of the base, and the oil nozzle is used to provide oil into the nozzle chip;

[0006] The airflow provided by the compressed air joint is used to blow the oil agent of the nozzle chip into oil mist, so that the oil mist can be evenly blown on the polyester yarn. The front and rear sides of the base are provided with scraping assemblies for the polyester yarn to pass through. A connecting plate is rotatably provided on the base, and a wire pressing rod is fixedly installed on the connecting plate. The wire pressing rod is provided with a plurality of grooves at equal intervals.

[0007] Preferably, the scraping assembly comprises a fixing plate fixedly mounted on the base, a plurality of placement grooves are formed on the fixing plate at equal intervals, and a wire guide is fixedly mounted in the placement groove.

[0008] Preferably, the wire guide and the circular hole are aligned with each other.

[0009] Preferably, two scraping blocks are fixedly connected to the opening of the wire guide.

[0010] Preferably, the scraping block is an arc-shaped block, and the gap between the two scraping blocks is smaller on one side and larger on the other side.

[0011] Preferably, the side with the larger gap between the two scraping blocks is the wire feeding end, and the side with the smaller gap is the wire outlet end.

[0012] Preferably, the distance between two adjacent wire guides is 6.5 mm.

[0013] Preferably, an elastic column is fixedly installed between the wire pressing rod and the connecting plate.

[0014] Preferably, the elastic column is made of rubber material.

[0015] Preferably, a wire guide wheel is rotatably connected in the groove on the wire pressing rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. Through the setting of the circular hole in the nozzle chip, the oil agent enters the nozzle chip through the oil nozzle, and the compressed air enters the nozzle chip through the compressed air joint to form an airflow. The airflow can blow the oil agent into oil mist. Since the cross-section of the circular hole is circular, when the polyester yarn passes through the circular hole, the oil mist can be evenly sprayed on the polyester yarn. The oil agent improves the uniformity of the oil film of a single polyester yarn, and can also make the polyester yarn bundle initially entangled, increase the bundling of the polyester yarn bundle, improve the defect of polyester yarn divergence, effectively reduce hairy yarns and broken yarns, and reduce the friction between the monofilaments, and make the monofilaments more cohesive, so that the subsequent twisting and unwinding process is smoother, and the spinning performance is improved.

[0018] Second, by setting the distance between two adjacent wire guides to 6.5 mm, the distance between two adjacent wire guides is narrow, the structure is compact, and the precision is high.

[0019] 3. The gap between the two scraping blocks is set to be smaller on one side and larger on the other side. The side with the larger gap is the wire inlet end, and the side with the smaller gap is the wire outlet end. The wire inlet end facilitates the polyester thread to pass through the circular hole on the nozzle chip, and then pass through the wire guide on the other side. Before the polyester thread enters the circular hole on the nozzle chip, the wire outlet end on one side (front side) of the base can preliminarily scrape off the hair on the polyester thread. After the nozzle chip is evenly coated with oil, the wire outlet end on the other side (rear side) of the base can scrape the polyester thread again. On the one hand, it can scrape off more oil so that the oil can be evenly coated on the polyester thread. On the other hand, it can extrude multiple polyester threads so that the multiple polyester threads are more tightly blended.

[0020] Fourth, the wire guide wheel is rotated and arranged on the groove. When the wire pressing rod contacts the polyester yarn, the wire guide wheel reduces the friction between the polyester yarn and the wire pressing rod. When the tension between the polyester yarns is too large, the elastic column has a certain elasticity. The wire pressing rod can be deflected under the action of a large tension, thereby avoiding the breakage of the polyester yarn due to excessive tension during the winding process of the polyester yarn.

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 6 The present invention provides a technical solution: a polyester POY pre-network device, comprising a base 1, a nozzle chip 2 is fixedly mounted on the base 1, the hole on the nozzle chip 2 is a circular hole 5, a compressed air connector 3 is fixedly mounted on the side of the base 1, the compressed air connector 3 is used to provide airflow to the nozzle chip 2, and an oil nozzle 4 is installed on the rear side of the base 1, and the oil nozzle 4 is used to provide oil into the nozzle chip 2.

[0030] The air flow provided by the compressed air connector 3 is used to blow the oil agent in the nozzle chip 2 into oil mist, so that the oil mist can be evenly blown on the polyester yarn. The front and rear sides of the base 1 are provided with scraping assemblies 6 for the polyester yarn to pass through. A connecting plate 7 is rotatably provided on the base 1, and a wire pressing rod 8 is fixedly installed on the connecting plate 7. A plurality of grooves are provided on the wire pressing rod 8 at equal intervals.

[0031] By setting the circular hole 5 in the nozzle chip 2, the oil agent enters the nozzle chip 2 through the oil nozzle 4, and the compressed air enters the nozzle chip 2 through the compressed air joint 3 to form an airflow. The airflow can blow the oil agent into oil mist. Since the cross-section of the circular hole 5 is circular, when the polyester yarn passes through the circular hole 5, the oil mist can be evenly sprayed on the polyester yarn. The oil agent improves the uniformity of the oil film of a single polyester yarn, and can also make the polyester yarn bundle initially entangled, increase the bundling of the polyester yarn bundle, improve the defect of the divergence of the polyester yarn strips, effectively reduce hairy yarns and broken yarns, and reduce the friction between the monofilaments, and make the monofilaments more cohesive, so that the subsequent twisting and unwinding process is smoother, and the spinning performance is improved.

[0032] Furthermore, the wire scraping assembly 6 includes a fixing plate 61 fixedly mounted on the base 1 , a plurality of placement grooves are formed on the fixing plate 61 at equal intervals, and a wire guide 62 is fixedly mounted in the placement groove.

[0033] The polyester thread first passes through the thread guide 62 on the front side of the base 1 , then passes through the circular hole 5 in the nozzle chip 2 , and passes through the thread guide 62 on the rear side of the base 1 .

[0034] Furthermore, the wire guide 62 and the circular hole 5 are aligned with each other.

[0035] Furthermore, two wire scraping blocks 63 are fixedly connected to the opening of the wire guide 62 .

[0036] Furthermore, the scraping block 63 is an arc-shaped block, and the gap between the two scraping blocks 63 is smaller on one side and larger on the other side.

[0037] The gap between the two scraping blocks 63 is set to be smaller on one side and larger on the other side. The wire inlet end 64 facilitates the polyester thread to pass through the circular hole 5 on the nozzle chip 2, and then pass through the wire guide 62 on the other side. Before the polyester thread enters the circular hole 5 on the nozzle chip 2, the wire outlet end 65 on the front side of the base 1 can preliminarily scrape off the hair on the polyester thread.

[0038] Furthermore, the side with a larger gap between the two scraping blocks 63 is a wire feeding end 64 , and the side with a smaller gap is a wire outlet end 65 .

[0039] After the polyester yarn is evenly coated with oil through the nozzle chip 2, the wire outlet end 65 on the other rear side of the base 1 can scrape the polyester yarn again. On the one hand, it can scrape off more oil so that the oil can be evenly coated on the polyester yarn. On the other hand, it can squeeze multiple polyester yarns so that the multiple polyester yarns are more tightly mixed.

[0040] Furthermore, the distance between two adjacent wire guides 62 is 6.5 mm, so that the distance between two adjacent wire guides 62 is narrow, the structure is compact, and the precision is high.

[0041] Furthermore, an elastic column 9 is fixedly installed between the wire pressing rod 8 and the connecting plate 7 .

[0042] Furthermore, the elastic column 9 is made of rubber material, and the rubber material has a certain elasticity.

[0043] Furthermore, a wire guide wheel 10 is rotatably connected in the groove on the wire pressing rod 8 .

[0044] When the wire pressing rod 8 contacts the polyester yarn, the wire guide wheel 10 reduces the friction between the polyester yarn and the wire pressing rod. When the tension between the polyester yarns is too large, the elastic column 9 has a certain elasticity. The wire pressing rod 8 can deflect under the action of a large tension, thereby avoiding the polyester yarn from breaking due to excessive tension during the winding process.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
