DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4The utility model provides a technical solution: a water retaining device for a water jet loom, comprising an intermediate supporting sheet 1, a first bracket 2, a side locking bolt 3, a side locking hole 4, a back clamp 5, a positioning bolt 6, a front clamp 7, a positioning nut 8, an intermediate water retaining cloth 9, a second bracket 10, a front locking bolt 11, a front locking hole 12, a positioning frame 13, a shrinking water retaining cloth 14 and an extrusion bolt 15, wherein one end of the intermediate supporting sheet 1 is vertically penetrated and installed with the first bracket 2, a side locking bolt 3 is installed on the side of one end of the intermediate supporting sheet 1, the end of the side locking bolt 3 is connected with the side locking hole 4, the side locking hole 4 is opened on the side of the first bracket 2, a back clamp 5 is fixed to the rear side of the bottom surface of the intermediate supporting sheet 1, and a back clamp 5 is fixed to the top of the front surface of the back clamp 5. Positioning bolt 6, the positioning bolt 6 passes through the hole opened on the front clamp 7, and a positioning nut 8 is installed at the end of the positioning bolt 6. The top of the front clamp 7 is connected and fixed to the front side of the bottom of the middle supporting sheet 1, and the inner bottom of the back clamp 5 and the front clamp 7 are both in contact with the top of the middle water retaining cloth 9. The other end of the middle supporting sheet 1 is vertically penetrated and installed with a second bracket 10, and the front side of the other end of the middle supporting sheet 1 is installed with a front locking bolt 11, and the end of the front locking bolt 11 is connected to the front locking hole 12, and the front locking hole 12 is opened on the front side of the second bracket 10, and the other end of the middle supporting sheet 1 is connected and fixed to the top of the rear side of the positioning frame 13, and a shrinking water retaining cloth 14 is installed in the positioning frame 13, and an extrusion bolt 15 is installed on the front side of the positioning frame 13.

[0021] In this example, the side locking bolts 3 and the side locking holes 4 are vertically distributed with respect to the first bracket 2, and the side locking holes 4 are evenly spaced on one side of the first bracket 2. The above structural design enables the relative position of the first bracket 2 and the middle supporting plate 1 to be conveniently adjusted and stably fixed.

[0022] The back clip 5 and the front clip 7 are both spring steel sheets, and are symmetrically distributed front and back about the center of the middle supporting thin plate 1. The above structural design makes the back clip 5 and the front clip 7 have strong elasticity and can stably clamp and fix the top of the middle water retaining cloth 9.

[0023] The positioning bolts 6 are distributed horizontally with equal intervals, and the horizontal plane where the centers of the positioning bolts 6 are located is higher than the horizontal plane where the centers of the back clip 5 and the front clip 7 are located. The above-mentioned structural design ensures that the bottom of the back clip 5 and the front clip 7 can fit with the top of the middle water retaining cloth 9 over a large area, thereby ensuring the stable installation of the middle water retaining cloth 9.

[0024] The center of the front locking hole 12 and the center of the side locking hole 4 are on the same horizontal plane, and the front locking holes 12 are distributed at equal intervals. The above structural design enables the relative position of the second bracket 10 and the middle support plate 1 to be easily adjusted and stably fixed, and can cooperate with the first bracket 2 to ensure that the middle support plate 1 is installed horizontally.

[0025] The front view shape of the positioning frame 13 is an elongated "凵" shape. Extrusion bolts 15 are installed at equal intervals on both sides of the front of the positioning frame 13. The above structural design can stably position the relatively narrow shrinkage water blocking cloth 14 and ensure the shielding effect of the shrinkage water blocking cloth 14.

[0026] Working principle: When using this device, first move the middle support thin plate 1 up and down to make the middle support thin plate 1 slide relative to the first support 2 and the second support 10 until the middle water blocking cloth 9 is aligned with the water spraying position of the water jet loom. Then screw the side locking bolt 3 into the aligned side locking hole 4 and screw the front locking bolt 11 into the aligned front locking hole 12 to stably fix the middle support thin plate 1.

[0027] When the size of the required shrinkage water blocking cloth 14 is small, select a middle water blocking cloth 9 of normal size. Place the top of the middle water blocking cloth 9 as Figure 2 shown between the back clamping piece 5 and the front clamping piece 7, rotate the positioning nut 8 to squeeze the front clamping piece 7 to fit with the back clamping piece 5, squeeze and fix the middle water blocking cloth 9. Then select a positioning frame 13 of appropriate size, connect and fix the rear side of the top of the positioning frame 13 to a suitable position on the front side of the middle support thin plate 1, insert the shrinkage water blocking cloth 14, and rotate the extrusion bolt 15 to squeeze and fix the edge of the shrinkage water blocking cloth 14.

[0028] If the size of the required shrinkage water blocking cloth 14 is large, then directly do not install the positioning frame 13 and the shrinkage water blocking cloth 14, select a middle water blocking cloth 9 with a longer vertical length for installation,省去 the installation and debugging of the positioning frame 13 and the shrinkage water blocking cloth 14, and comprehensively shield the splashing water flow. This is the working principle of the water blocking device for this water jet loom.
