Abstract
Description
Technical Field
[0001] The present application relates to the field of weaving technology, and in particular to a height adjustment tool for a fingerboard on a loom. Background Art
[0002] A loom is a machine used to process raw materials such as thread, silk, and hemp into threads and then weave them into cloth. A plurality of upper finger plates are usually arranged on the frame of the loom, which can press against the cloth to prevent the cloth from moving during the weaving process, thereby ensuring the weaving quality of the cloth.
[0003] During the operation of the loom, the upper fingerboard will deviate downward due to the vibration of the loom. After the deviation, the upper fingerboard can no longer effectively press against the cloth. At this time, the loom needs to be stopped and the height of the upper fingerboard needs to be adjusted using a wrench. However, due to the small gap between adjacent upper fingerboards, the wrench cannot be directly inserted into the gap to adjust the upper fingerboard. At this time, more auxiliary means are needed to complete the height adjustment of the upper fingerboard, which not only greatly increases the difficulty of adjusting the upper fingerboard, but also affects the weaving efficiency of the cloth. Utility Model Content

[0032] The present application is further described in detail below in conjunction with the accompanying drawings.
[0033] like Figure 2 As shown, the loom includes a frame 100 for carrying a cloth 102, a plurality of upper finger plates 101 arranged at intervals on the frame 100 for pressing the cloth 102, and a gap is provided between each two adjacent upper finger plates 101. The loom is of prior art, and the rest of the structure of the loom is not described here.
[0034] See also Figure 1-2As shown, a height adjustment tool for the upper finger plate of a loom is shown, which includes an adjusting rod 1 for inserting a gap, an adjusting head 2 arranged at the end of the adjusting rod 1, and a slot 3 for accommodating the upper finger plate 101 is opened on the adjusting head 2, and the slot 3 matches the outer contour of the upper finger plate 101.
[0035] When in use, the adjusting rod 1 can be directly inserted into the gap between adjacent upper finger plates 101, and then the slot 3 on the adjusting head 2 is put on the upper finger plate 101. The upper finger plate 101 can be conveniently lifted by turning the adjusting rod 1 downward, thereby achieving height adjustment of the upper finger plate 101, which greatly reduces the adjustment difficulty of the upper finger plate 101 and improves the adjustment efficiency, thereby improving the overall weaving efficiency of the fabric 102.
[0036] In this embodiment, combined with Figure 1 As shown, the adjusting head 2 is arranged on the side of the adjusting rod 1, and includes two parallel gear rods 21, the length direction of the two gear rods 21 is perpendicular to the length direction of the adjusting rod 1, and a slot 3 is formed between the two gear rods 21, and the slot direction is perpendicular to the length direction of the adjusting rod 1.
[0037] After the adjusting rod 1 is inserted into the gap, the two shift rods 21 located on the sides of the adjusting rod 1 can be directly engaged with the two sides of the upper finger plate 101, and the slot 3 can be directly engaged with the upper finger plate 101 on the side of the gap, so as to facilitate the adjustment of the upper finger plate 101; at the same time, the two shift rods 21 can respectively resist the two sides of the upper finger plate 101, and when the adjusting rod 1 is rotated, the two shift rods 21 can serve as a rotation fulcrum, so that the rotation of the adjusting rod 1 can be more labor-saving.
[0038] In this embodiment, both sides of the slot 3 are rough surfaces, on which lines 31 are arranged. The lines 31 can increase the friction between the slot wall of the slot 3 and the upper fingerboard 101, improve the clamping strength between the slot 3 and the upper fingerboard 101, and prevent the upper fingerboard 101 from falling off from the slot 3 during the adjustment process.
[0039] In this embodiment, the adjusting head 2 further includes a first connecting rod 22 connected to the adjusting rod 1 at one end, two shift rods 21 are connected to one side of the first connecting rod 22, and a side of the first connecting rod 22 away from the shift rod 21 has an arc-shaped clearance surface 23. When the adjusting head 2 adjusts the upper finger plate 101 on one side of the gap, the clearance surface 23 can provide clearance space for the upper finger plate 101 on the other side of the gap, thereby preventing the adjusting head 2 from touching the upper finger plate 101 on the other side of the gap during the adjustment process and causing the upper finger plate 101 to deviate.
[0040] In this embodiment, the height adjustment tool further includes a second connecting rod 4 whose two ends are respectively connected to the adjustment rod 1 and the first connecting rod 22, and the second connecting rod 4 is bent along the direction from the adjustment rod 1 to the first connecting rod 22 toward the direction of the vertical gear rod 21. The bent second connecting rod 4 can effectively prevent the adjustment rod 1 from touching the fabric 102 during the rotation process and causing damage to the fabric 102.
[0041] A clearance groove 5 is provided on the side of the second connecting rod 4, and the notch direction of the clearance groove 5 is the same as the notch direction of the clamping groove 3. The clearance groove 5 can prevent the adjusting rod 1 from interfering with the frame 100 during the rotation process.
[0042] In this embodiment, the adjusting head 2, the second connecting rod 4 and the adjusting rod 1 are integrally formed, which can ensure the structural strength of the adjusting head 2 and avoid relative fracture of the adjusting head 2 and the adjusting rod 1 during the adjustment process.
[0043] The implementation principle of a height adjustment tool in the embodiment of the present application is:
[0044] The adjusting rod 1 can be directly inserted into the gap between adjacent upper finger plates 101, and then the adjusting head 2 is moved sideways to make the slot 3 engage with the upper finger plate 101, and then the adjusting rod 1 is rotated downward, and the two gear rods 21 serve as the rotation fulcrums of the adjusting rod 1 respectively, and the three cooperate with each other to achieve the height adjustment of the upper finger plate 101.
[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
