Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, specifically to a weft insertion mechanism and a water jet loom. Background Technology

[0002] The weft insertion mechanism of the existing water jet loom includes a water pump, a connecting rod, and a cam. The cam is mounted on the wall plate via a camshaft and rotates with the camshaft. The connecting rod is mounted on the wall plate via a connecting rod shaft and can rotate around the connecting rod shaft. One end of the connecting rod is provided with a roller that contacts and engages with the cam, and the other end of the connecting rod is connected to the plunger of the water pump via a connecting piece. When the cam rotates, it drives the connecting rod to rotate through the roller, thereby realizing the reciprocating motion of the plunger of the water pump, thus completing the process of water pump suction and drainage. During operation, the cam drives the connecting rod to rotate via rollers. The outer diameter of the contact point between the cam and the rollers changes continuously from large to small and then back to large. As the outer diameter of the contact point changes, a radial force is generated between the cam and the rollers, and this radial force is constantly changing. This causes the ends of both the camshaft and the connecting rod shaft to vibrate due to the radial force. This is especially true for the camshaft that drives the cam to rotate. The cam is located at the end of the camshaft and is a certain distance from the camshaft bearing. This means that the end of the camshaft is affected not only by the weight of the cam but also by the radial force generated between the cam and the rollers. As a result, the vibration at the end of the camshaft is greater, which not only affects the service life of the camshaft bearings but also the stability of the water pump plunger's extension and retraction stroke. This makes it impossible to effectively guarantee the stability of the weft insertion process in the water jet loom, and it is easy to cause problems such as poor weft insertion that affect the fabric quality. Utility Model Content

[0003] The purpose of this invention is to overcome the aforementioned problems in the prior art and provide a weft insertion mechanism that can achieve stable weft insertion on a water jet loom, thereby effectively ensuring the quality of the fabric.

[0004] To achieve the above objectives, this utility model provides a weft insertion mechanism, which includes a water pump, a cam, and a connecting rod. The cam is mounted on the wall plate of a water jet loom via a camshaft, and the connecting rod is mounted on the wall plate via a connecting rod shaft. The mechanism is characterized in that it further includes a stabilizer, which includes a cam end and a fixed end.

[0005] The cam end is mounted on the first end of the cam shaft that extends out of the cam via a bearing;

[0006] The fixed end is fixedly disposed on the wall panel.

[0007] In an optional embodiment of the present invention, the stabilizer further includes a connecting rod end, which is fixedly disposed at the first end of the connecting rod shaft extending from the connecting rod.

[0008] In an optional embodiment of this utility model, the water pump includes an upper flange hole and an upper bolt, the upper bolt passing through the fixed end and the upper flange hole in sequence and being fixedly connected to the wall panel.

[0009] In an optional embodiment of the present invention, the stabilizer includes a central cutout to expose the connecting rod and the rollers on the connecting rod.

[0010] In an optional embodiment of this invention, the stabilizer is triangular.

[0011] In an optional embodiment of the present invention, a bearing cover is further included, which covers the outside of the bearing at the cam end and is fixedly connected to the stabilizer.

[0012] In an optional embodiment of this invention, the stabilizer is perpendicular to the camshaft.

[0013] This utility model also provides a water jet loom, including the aforementioned weft insertion mechanism.

[0014] This utility model's weft insertion mechanism incorporates a stabilizing frame. The cam end of the stabilizing frame is mounted on the first end of the cam shaft extending from the cam via a bearing. The fixed end of the stabilizing frame is fixedly mounted on the wall plate, thus connecting the first end of the cam shaft to the wall plate. The stabilizing frame effectively counteracts the gravity from the cam and the radial force from the roller through the support of the wall plate, solving the problem of poor weft insertion caused by cam shaft vibration in the prior art, and effectively ensuring product quality.

[0025] like Figure 1-4As shown, this utility model embodiment provides a weft insertion mechanism, which includes a water pump 1, a cam 2, and a connecting rod 3. The cam 2 is mounted on the wall plate 7 of the water jet loom via a camshaft 5, and the connecting rod 3 is mounted on the wall plate 7 via a connecting rod shaft 6. The weft insertion mechanism also includes a stabilizer 4, which includes a cam end 41 and a fixed end 43. The cam end 41 is mounted on the first end of the cam 2 extending from the camshaft 5 via a bearing. The fixed end 43 is fixedly mounted on the wall plate 7.

[0026] In this embodiment, the working relationship between the water pump of the weft insertion mechanism and the cam and connecting rod is prior art and will not be described in detail here.

[0027] In this embodiment, the structure of the stabilizer 4 is mainly used to establish a fixed connection between the first end of the camshaft 5 and the wall panel, so that the first end of the camshaft 5 is effectively supported. The structure of the stabilizer 4 is not specifically limited, as long as it can achieve the above function.

[0028] In this embodiment, the cam end 41 of the stabilizer 4 is engaged with the first end of the protruding cam 2 of the camshaft 5 through a bearing, which can fix the first end of the camshaft 5 without affecting the normal rotation of the camshaft 5.

[0029] In the existing technology, when cam 2 drives connecting rod 3 to rotate via roller 30 on connecting rod 3, an interactive radial force is generated between cam 2 and roller 30. This causes the end of camshaft 5 furthest from wall plate 7 to receive not only the weight of the cam but also the radial force from the roller. The combined force of these two forces causes irregular vibration of camshaft 5. The vibration of camshaft 5 during operation affects the service life of the bearings that mate with camshaft 5 and also affects the stability of the weft insertion process. Because the vibration of camshaft 5 directly affects the normal working stroke of the plunger of water pump 1, it can easily lead to poor weft insertion, thereby affecting the fabric quality.

[0030] This utility model's weft insertion mechanism, by setting a stabilizing frame 4, has its cam end 41 mounted on the first end of the cam 2 extending from the cam shaft 5 via a bearing, and its fixed end 43 fixedly mounted on the wall plate 7, so that the first end of the cam shaft 5 and the wall plate 7 are fixedly connected together by the stabilizing frame 4. The stabilizing frame 4 can effectively counteract the gravity from the cam 2 and the radial force from the roller 30 through the support of the wall plate 7, solving the problem of poor weft insertion caused by the vibration of the cam shaft 5 in the prior art, thus effectively ensuring product quality.

[0031] Optionally, since the connecting rod 3 is also a certain distance from the wall plate 7, it is driven by the cam and the water pump to swing back and forth during operation. Therefore, the end of the connecting rod shaft 6 extending out of the wall plate is also prone to vibration due to various forces, which will also affect the stability of the weft insertion operation. To solve this problem, the stabilizer 4 also includes a connecting rod end 42, which is fixedly set at the second end of the connecting rod 3 extending out of the connecting rod shaft 6. By setting the connecting rod end 42 of the stabilizer 4, the connecting rod shaft 6 and the end of the cam shaft 5 extending out of the wall plate are connected as one unit. This not only solves the stability problem of the connecting rod shaft 6, but also prevents relative movement between the cam shaft 5 and the connecting rod shaft 6. Even if the equipment vibrates as a whole due to external influences, it will not interfere with the cooperation between the rollers of the cam and the connecting rod, making the overall structure of the weft insertion mechanism more stable and robust.

[0032] Furthermore, although the water pump is fixed to the wall panel 7, it is also part of the weft insertion mechanism. To prevent the entire equipment from vibrating and affecting the coordination between the water pump, cam, and connecting rod, the water pump 1 includes an upper flange hole 10 and upper bolts 11. The upper bolts 11 are sequentially passed through the fixed end 43 of the stabilizer 4 and the upper flange hole 10 to fix it to the wall panel 7. This not only makes the water pump, cam, and connecting rod an effective whole, achieving resonance at the same frequency and unaffected by external influences, but also makes full use of the existing upper flange hole connection structure of the water pump, further reducing processing costs.

[0033] Preferably, since the stabilizer 4 is located on the outermost side away from the wall panel 7, in order to facilitate viewing the cooperation between the cam and the roller and the rotation of the connecting rod, the stabilizer 4 includes a central hollow 44 to expose the connecting rod 3 and the roller 30 on the connecting rod 3. Moreover, setting the stabilizer 4 in a hollow shape can also reduce the overall weight of the stabilizer 4 and prevent it from affecting its support function due to excessive weight.

[0034] Furthermore, in order to achieve better support for the first end of the camshaft and connecting rod shaft by the stabilizer 4, the stabilizer 4 is triangular.

[0035] Optionally, in order to protect the bearing between the stabilizer and the camshaft, a bearing cover 8 can be provided, which covers the outside of the bearing at the cam end 41 and is fixedly connected to the stabilizer 4.

[0036] Alternatively, in order to more effectively support the first ends of the camshaft 5 and the connecting rod shaft 6, the stabilizer 4 is set to be perpendicular to the camshaft 5, so that the stabilizer 4 can provide more stable and effective support to both.

[0037] An embodiment of this utility model also discloses a water jet loom, including the above-mentioned weft insertion mechanism. The water jet loom of this utility model has a more stable weft insertion mechanism, which can fully guarantee the stability of the weft insertion process, thereby effectively ensuring the fabric quality.

[0038] This utility model of a fabric roll bearing seat enables convenient and efficient assembly and disassembly of the fabric roll bearing, effectively avoiding the problem of the fabric roll bearing getting stuck and difficult to disassemble in the prior art.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
