Description

Technical Field

[0001] This utility model relates to the field of water jet loom technology, and in particular to a weft insertion system for a water jet loom. Background Technology

[0002] Water jet looms use water as the weft insertion medium. The jet of water creates frictional traction on the weft yarn, drawing it into the shed where it interweaves with the warp yarns to form a fabric. The scissor assembly is mounted on the drive shaft via a transmission linkage. The weft insertion system of the water jet loom includes a water pump, an inlet check valve mounted on the water pump's inlet end, an outlet check valve mounted on the water pump's outlet end, an inlet pipe connected to the inlet check valve, an outlet pipe connected to the outlet check valve, and a nozzle connected to the outlet pipe.

[0003] For example, Chinese patent CN219731203U, with an authorization announcement date of September 22, 2023, discloses "A Multi-Jet Weft Insertion System for a Water Jet Loom". During installation, the connecting piece of the multi-connector is first fixed to the frame of the water jet loom, and the thread fastener is also fixed to the frame. Then, by adjusting the connection positions of multiple hoses and the thread fastener, the bending degree of the hoses can be adjusted, thereby regulating the resistance of the water flow within the hoses. Finally, with the help of a pressure sensor and a display, the water pressure entering the nozzles from the hoses is stabilized at a specific value or range, and the hoses are then fixed using a locking assembly. Ultimately, this improves the pressure uniformity of the water jets from multiple nozzles.

[0004] In the aforementioned comparative patent, because the water jet loom sprays water intermittently, each spray of water exerts a force on each hose. The portion of each hose located between the multi-connector and the wire fastener, and the portion located between the wire fastener and the nozzle, are prone to change in their bending shape after being subjected to the spray of water, thereby affecting the pressure of the spray of water. Utility Model Content

[0005] The purpose of this invention is to provide a weft insertion system for a water jet loom, which improves the pressure uniformity of the water jet.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a weft insertion system for a water jet loom, comprising a water pump, an inlet check valve installed at the inlet end of the water pump, an outlet check valve installed at the outlet end of the water pump, an outlet pipe connected to the outlet check valve, a multi-way connector connected to the outlet pipe, a connecting seat, a plurality of nozzles installed side by side on the connecting seat, a plurality of connecting hoses disposed between the multi-way connector and the plurality of nozzles, a pressure sensor disposed at the inlet end of the nozzle, a display connected to the pressure sensor signal, and a fixing assembly for fixing the plurality of connecting hoses, wherein the multi-way connector has a plurality of outlet connectors arranged side by side, and the distance between two adjacent outlet connectors is the same as the distance between two adjacent nozzles; the fixing assembly includes a mounting bracket for fixing on the frame of the water jet loom, a plurality of first adjusting components disposed at the upper end of the mounting bracket for adjusting the curvature of the connecting hoses near the nozzles, and a plurality of second adjusting components disposed at the lower end of the mounting bracket for adjusting the curvature of the connecting hoses near the outlet connectors.

[0007] The present invention is further configured as follows: the first adjustment component includes a base mounted on a mounting bracket and having a spherical groove larger than a semicircle, a spherical head movably disposed in the spherical groove, a locking knob bolt threaded to the base and used to abut against the periphery of the spherical head, a first support rod disposed on the spherical head, and a first plastic sleeve disposed at one end of the first support rod and for embedding a connecting hose.

[0008] A further feature of this invention is that the second adjustment assembly includes a lifting seat that is lifted and lowered on the mounting frame, an adjustment component disposed between the lifting seat and the mounting frame for adjusting the height of the lifting seat, a second support rod disposed on the lifting seat, and a second plastic sleeve disposed at one end of the second support rod for embedding a connecting hose.

[0009] A further feature of this invention is that the adjusting component includes a first adjusting knob bolt threadedly connected to the mounting bracket and having its upper end pressed against the lower surface of the lifting seat, and a second adjusting knob bolt threadedly connected to the mounting bracket and having its lower end pressed against the upper surface of the lifting seat.

[0010] A further feature of this invention is that the connecting hose is embedded in the first plastic sleeve and the second plastic sleeve and is wrapped with a flexible protective sleeve.

[0011] In summary, the beneficial effects of this utility model are:

[0012] 1. The multi-port connector has multiple water outlets arranged side by side, and the distance between two adjacent water outlets is the same as the distance between two adjacent nozzles. In this case, the multiple connecting hoses can be kept at a consistent angle and orientation after installation, thereby improving the pressure uniformity of the overall multi-jet water flow. At the same time, since the nozzles are installed at a horizontal angle and the water outlets are located below the nozzles, the connecting hoses will bend to a certain extent at both ends during connection. At this time, the degree of bending of the connecting hose near the nozzle is adjusted by the first adjustment component, and the angle of bending of the connecting hose near the water outlet is adjusted by the second adjustment component, thereby avoiding excessive bending angle and ensuring the smooth flow of the jet water in the connecting hose.

[0013] 2. At the first adjustment component, since the nozzle is installed at a downward horizontal angle, the bending angle of the connecting hose will be relatively large. At this time, by setting up the base, ball head, first support rod, and first plastic sleeve, the bending point of the connecting hose near the nozzle can be adjusted to avoid excessive bending angle.

[0014] 3. At the second adjustment component, by adjusting the height of the second plastic sleeve, the angle of the connecting hose between the water outlet connector and the second plastic sleeve is changed, thereby avoiding excessive bending angle;

[0015] 4. The flexible protective sleeve can achieve shock absorption and cushioning, while eliminating the gap at the connection with the first plastic sleeve and the second plastic sleeve. Attached Figure Description

[0021] This specific embodiment is merely an explanation of the present invention and is not intended to limit the scope of the invention.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Example: A weft insertion system for a water jet loom, such as Figure 1 As shown, it includes a water pump 1, an inlet check valve 2 installed on the inlet end of the water pump 1, an outlet check valve 3 installed on the outlet end of the water pump 1, an outlet pipe 4 connected to the outlet check valve 3, a multi-way connector 5 connected to the outlet pipe 4, a connecting seat 6, multiple nozzles 7 installed side by side on the connecting seat 6, multiple connecting hoses 8 disposed between the multi-way connector 5 and the multiple nozzles 7, a pressure sensor 9 disposed on the inlet end of the nozzles 7, a display 10 connected to the pressure sensor 9, and a fixing assembly 11 for fixing the multiple connecting hoses 8.

[0024] like Figure 1 and Figure 2 As shown, the multi-port connector 5 has multiple outlet connectors 51 arranged side by side, and the spacing between two adjacent outlet connectors 51 is the same as the spacing between two adjacent nozzles 7; the fixing assembly 11 includes a mounting bracket 11-1 for fixing on the frame of the water jet loom, multiple first adjusting assemblies 11-2 arranged on the upper end of the mounting bracket 11-1 for adjusting the curvature of the connecting hose 8 near the nozzle 7, and multiple second adjusting assemblies 11-3 arranged on the lower end of the mounting bracket 11-1 for adjusting the curvature of the connecting hose 8 near the outlet connector 51.

[0025] like Figures 2 to 4As shown, the first adjustment assembly 11-2 includes a base 11-21 mounted on the mounting bracket 11-1 and having a spherical groove larger than a semicircle, a spherical head 11-22 movably disposed in the spherical groove, a locking knob bolt 11-23 threadedly connected to the base 11-21 and used to abut against the periphery of the spherical head 11-22, a first support rod 11-24 disposed on the spherical head 11-22, and a first plastic sleeve 11-25 disposed at one end of the first support rod 11-24 and for the insertion of the connecting hose 8.

[0026] like Figures 2 to 4 As shown, the second adjustment assembly 11-3 includes a lifting seat 11-31 that is lifted and lowered on the mounting frame 11-1, an adjusting member 11-32 disposed between the lifting seat 11-31 and the mounting frame 11-1 for adjusting the height of the lifting seat 11-31, a second support rod 11-33 disposed on the lifting seat 11-31, and a second plastic sleeve 11-34 disposed at one end of the second support rod 11-33 for embedding the connecting hose 8. The adjusting member 11-32 includes a first adjusting knob bolt 11-321 threadedly connected to the mounting frame 11-1 and with its upper end abutting against the lower surface of the lifting seat 11-31, and a second adjusting knob bolt 11-322 threadedly connected to the mounting frame 11-1 and with its lower end abutting against the upper surface of the lifting seat 11-31.

[0027] like Figures 2 to 4 As shown, a flexible protective sleeve 12 is provided at the positions of the first plastic sleeve 11-25 and the second plastic sleeve 11-34, and the connecting hose 8 is embedded in them.

[0028] Implementation effect: The multi-port connector 5 has multiple water outlet connectors 51 arranged side by side, and the distance between two adjacent water outlet connectors 51 is the same as the distance between two adjacent nozzles 7. At this time, the multiple connecting hoses 8 can be installed at a consistent angle and orientation, thereby improving the pressure uniformity of the overall multi-jet water flow. At the same time, since the nozzles 7 are installed at a horizontal angle and the water outlet connectors 51 are located below the nozzles 7, the two ends of the connecting hoses 8 will be bent to a certain extent when connected. At this time, the degree of bending of the connecting hoses 8 near the nozzles 7 is adjusted by the first adjusting component 11-2, and the angle of bending of the connecting hoses 8 near the water outlet connectors 51 is adjusted by the second adjusting component 11-3, thereby avoiding excessive bending angle and ensuring the smooth flow of the jet water flow in the connecting hoses 8.

[0029] At the first adjustment assembly 11-2, because the nozzle 7 is installed at a downward horizontal angle, the bending angle of the connecting hose 8 will be relatively large. The base 11-21, ball head 11-22, first support rod 11-24, and first plastic sleeve 11-25 allow adjustment of the bending point of the connecting hose 8 near the nozzle 7, preventing excessive bending. At the second adjustment assembly 11-3, adjusting the height of the second plastic sleeve 11-34 changes the angle of the connecting hose 8 between the water outlet connector 51 and the second plastic sleeve 11-34, thus preventing excessive bending. The flexible protective sleeve 12 provides shock absorption and eliminates gaps at the connection points with the first and second plastic sleeves 11-25 and 11-34.
