Description

Technical Field

[0001] This utility model relates to the technical field of water jet loom accessories, and in particular to an adjustable nozzle mounting mechanism for a water jet loom. Background Technology

[0002] Water jet looms use water as the weft insertion medium. The jet of water generates frictional traction on the weft yarn, causing it to enter the shed and interweave with the warp yarns to form a fabric. The weft insertion device of a water jet loom includes a water pump, an inlet check valve installed at the water pump's inlet end, an outlet check valve installed at 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] The nozzle is fixed to the nozzle connector seat during installation. For example, Chinese Patent No. CN208309068U, with an authorization announcement date of January 1, 2019, discloses a nozzle connector seat for a water jet loom, which includes a fixed base for mounting on the frame of the water jet loom and a movable block for mounting the nozzle. The fixed base can be adjusted in the horizontal direction to adjust the installation position, and the movable block can be adjusted in the vertical direction to adjust the installation device, thereby ultimately adjusting the installation position of the nozzle.

[0004] However, in the aforementioned comparative patent, when adjusting the position of the base in the horizontal direction and the position of the movable block in the vertical direction, it is necessary to first unlock and fix the base and the movable block before it can be moved. After adjusting the position, it is necessary to fix it, which leads to the problem of inconvenience in adjustment. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable nozzle mounting mechanism for a water jet loom, which facilitates the adjustment of the nozzle mounting position.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an adjustable nozzle mounting mechanism for a water jet loom, comprising a base for mounting on the frame of the water jet loom, a horizontal adjusting seat slidably connected to the base in the horizontal direction, a vertical adjusting block slidably mounted on the horizontal adjusting seat in the vertical direction, and a nozzle mounted on the vertical adjusting block. The base has a first sliding groove extending horizontally and for sliding of the horizontal adjusting seat. The base has a first oblong hole communicating with the first sliding groove. A first limiting tooth groove is provided on the rear side of the base. One end of the horizontal adjusting seat has a first connecting shaft extending through the first oblong hole.

[0007] By adopting the above technical solution, the horizontal position of the nozzle can be adjusted by the horizontal adjusting seat, and the vertical position can be adjusted by the vertical adjusting block. When adjusting the position of the horizontal adjusting seat, an external force that overcomes the first compression spring is applied to the first limiting rack block, causing the first limiting rack block and the first limiting tooth groove to separate, thereby enabling the horizontal adjusting seat to be moved for position adjustment. After adjusting the position, the first limiting rack block is released, and under the reset action of the first compression spring, the first limiting rack block and the second limiting tooth groove are engaged to achieve fixation. Similarly, the position of the vertical adjusting block can be adjusted. Finally, the adjustment operation of the horizontal adjusting seat and the vertical adjusting block is convenient, which facilitates the adjustment of the nozzle installation position.

[0008] A further feature of this invention is that: the first limiting rack block is provided with a first lifting block to facilitate overcoming the elastic force of the first compression spring and thus separating the first limiting rack block and the first limiting tooth groove; and the second limiting rack block is provided with a second lifting block to facilitate overcoming the elastic force of the second compression spring and thus separating the second limiting rack block and the second limiting tooth groove.

[0009] By adopting the above technical solution, during the operation of applying an external force to the first limiting rack block to overcome the first compression spring, the first lifting block has the function of facilitating the application of force to the first limiting rack block, and similarly, the second lifting block has the function of facilitating the application of force to the second limiting rack block.

[0010] A further feature of this invention is that: a plurality of first limiting strips arranged in a circumferential array are provided on the periphery of the first connecting shaft, and the first limiting rack block is slidably disposed on the plurality of first limiting strips; a plurality of second limiting strips arranged in a circumferential array are provided on the periphery of the second connecting shaft, and the second limiting rack block is slidably disposed on the plurality of second limiting strips.

[0011] By adopting the above technical solution, multiple first limiting strips can circumferentially limit the sliding of the first limiting rack block to prevent the first limiting rack block from rotating; similarly, multiple second limiting strips can prevent the second limiting rack block from rotating.

[0012] A further feature of this invention is that an adjusting screw, the upper end of which extends into the lower end of the second sliding groove, is threaded onto the horizontal adjusting seat, and the adjusting screw is used to press against the bottom of the vertical adjusting block.

[0013] By adopting the above technical solution, the adjusting screw can be pressed against the bottom of the vertical adjusting block to support and reinforce the bottom of the vertical adjusting block.

[0014] A further feature of this invention is that the upper end of the adjusting screw is provided with a rubber pad for pressing against the bottom of the vertical adjusting block.

[0015] By adopting the above technical solution, the rubber pad has the function of buffering during support.

[0016] A further feature of this invention is that the horizontal adjustment seat is in the shape of an inverted "T", and the horizontal adjustment seat includes a sliding end that is slidably connected in a first sliding groove, a connecting end that is connected to the sliding end and has a second sliding groove, and the adjusting screw is threadedly connected to the bottom of the connecting end.

[0017] By adopting the above technical solution, the horizontal adjustment seat includes a sliding end that is slidably connected in the first sliding groove and a connecting end that is connected to the sliding end and has a second sliding groove, thereby realizing the horizontal adjustment of the horizontal adjustment seat and the vertical adjustment of the vertical adjustment block.

At the same time, connecting brackets 14 for fixing to the frame of the water jet loom are respectively embedded at both ends of the base located in the first sliding groove 11. The connecting brackets 14 and the base 1 are detachably connected, and the base 1 can be fixed after the two connecting brackets 14 are installed.

[0027] For example, 1 to Figure 4As shown, the base 1 is provided with a first waist-shaped hole 12 communicating with the first sliding groove 11, and the base 1 is provided with a first limiting tooth groove 13 on the rear side. One end of the sliding end 21 of the horizontal adjustment seat 2 is provided with a first connecting shaft 51 that passes through the first waist-shaped hole 12. A first limiting toothed block 52 for embedding in the first limiting tooth groove 13 to achieve limiting is sleeved on the first connecting shaft 51. A first anti-detachment end cap 53 is provided at the end of the first connecting shaft 51. A first compression spring 54 is sleeved on the first connecting shaft 51 with both ends abutting between the first anti-detachment end cap 53 and the first limiting toothed block 52.

[0028] like Figure 3 and Figure 4 As shown, the first limiting rack block 52 is provided with a first lifting block 521 to facilitate the separation of the first limiting rack block 52 and the first limiting tooth groove 13 by overcoming the elastic force of the first compression spring 54. A plurality of first limiting strips 511 are arranged in a circumferential array on the periphery of the first connecting shaft 51, and the first limiting rack block 52 is slidably disposed on the plurality of first limiting strips 511.

[0029] like Figures 1 to 3 , Figure 5 As shown, the connecting end 22 of the horizontal adjustment seat 2 is provided with a second sliding groove 221 extending in the vertical direction and for the vertical adjustment block 3 to slide.

The rear side of the horizontal adjustment seat 2 is provided with a second limiting tooth groove 223. The lower end of the vertical adjustment block 3 is provided with a second connecting shaft 61 that passes through the second waist-shaped hole 222. A second limiting rack block 62 for embedding in the second limiting tooth groove 223 to achieve limiting is sleeved on the second connecting shaft 61. A second anti-detachment end cap 63 is provided at the end of the second connecting shaft 61. A second compression spring 64 with both ends abutting between the second anti-detachment end cap 63 and the second limiting rack block 62 is sleeved on the second connecting shaft 61.

[0030] like Figure 3 and Figure 5 As shown, the second limiting rack block 62 is provided with a second lifting block 632 to facilitate overcoming the elastic force of the second compression spring 64 and thus separating the second limiting rack block 62 from the second limiting tooth groove 223.
