Description

Technical Field

[0001] This invention relates to the field of fiberglass cloth weaving machine technology, and in particular to an adjustable reed assembly for an electronic grade fiberglass cloth weaving machine. Background Technology

[0002] Electronic-grade fiberglass cloth is a basic material for printed circuit boards and is widely used in various electronic fields. It is woven using electronic cloth weaving machines.

[0003] In an electronic fabric weaving machine, the reed is composed of multiple reed blades arranged and connected at intervals. The warp yarns pass through each reed blade, thereby combing the warp yarns of the fabric and beating the weft, so that the warp and weft interweave to form the fabric surface.

[0004] When the required fabric width increases, the number of head lengths needs to be adjusted accordingly. Due to the limitation of reed length, increasing the number of head lengths can easily lead to insufficient reed space, making it impossible to install the weft detector and thread the yarn clips. Replacing the reed with a longer one requires reinstalling the weft detector and threading the yarn clips, thus reducing work efficiency. Summary of the Invention

[0005] The summary section of this invention provides a brief overview of the concepts, which will be described in detail in the detailed description section that follows. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0006] Some embodiments of the present invention provide a width-adjustable reed assembly for an electronic-grade fiberglass cloth weaving machine to solve the technical problems mentioned in the background section above.

[0007] Some embodiments of the present invention provide an adjustable reed assembly for an electronic-grade fiberglass cloth weaving machine, comprising a main reed, a secondary reed, a reed seat, and a pressure block, wherein... The main reed and the secondary reed are detachably connected in an interlocking manner. The secondary reed is used to install the weft detector and thread the yarn. The reed base is provided with an assembly groove for placing the main reed and the auxiliary reed; the pressure block is installed between the main reed, the auxiliary reed and the assembly groove to fix the main reed and the auxiliary reed.

[0008] Optionally, the two surfaces of the assembly groove are a straight wall and an inclined wall, respectively.

[0009] Optionally, the bottoms of the main reed and the auxiliary reed are engaged with the bottom surface of the assembly groove; the main reed and the auxiliary reed are engaged with the straight wall of the assembly groove.

[0010] Optionally, the pressure block has an inclined surface, the slope of which is the same as the slope of the inclined wall of the assembly groove.

[0011] Optionally, in the assembled state, the inclined surface of the pressure block presses against the inclined wall of the assembly groove, so that the main reed and the auxiliary reed are tightly joined to the straight wall of the assembly groove.

[0012] Optionally, the height of the pressure block is the same as the height of the assembly groove.

[0013] Optionally, a pressure plate is provided at the upper end of the pressure block and the assembly groove, and the pressure plate, pressure block and assembly groove are fixedly connected by bolts.

[0014] Optionally, the connection end of the main reed and the secondary reed is provided with a cutting surface; in the assembled state, the two cutting surfaces are joined together, and the thickness of the connection is the same as the thickness of the main reed and the secondary reed.

[0015] Optionally, the cutting surface of the main reed is provided with a first protrusion and a first groove, and the cutting surface of the secondary reed is correspondingly provided with a second groove and a second protrusion; in the assembled state, the first protrusion and the first groove cooperate with the second groove and the second protrusion respectively to achieve a fitting connection.

[0016] Optionally, connecting holes are made on the cutting surfaces of the main reed and the secondary reed, and bolts are passed through the connecting holes to securely connect the main reed and the secondary reed.

[0017] The above embodiments of the present invention have the following beneficial effects: When the fabric width increases, remove the pressure block to separate the main reed and the auxiliary reed. There's no need to disassemble the weft detector or re-thread the yarn. After replacing the main reed with the wider one, connect it to the auxiliary reed, and then reinstall the pressure block. Because the weft detector remains installed on the auxiliary reed and the yarn is always threaded during the main reed replacement process, the steps of disassembling the weft detector and re-threading the yarn are eliminated, significantly improving work efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0024] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1 to 4 The adjustable reed assembly for an electronic-grade fiberglass cloth weaving machine of the present invention includes a main reed 1, a secondary reed 2, a reed seat 3, a pressure block 4, and a pressure plate 5.

[0026] The main reed 1 and the auxiliary reed 2 are detachably connected and fitted together. The reed seat 3 is used to hold the main reed 1 and the auxiliary reed 2. Specifically, the reed seat 3 is provided with an assembly groove, the two sides of which are a straight wall and an inclined wall, respectively.

[0027] In the assembled state, the bottoms of the main reed 1 and the auxiliary reed 2 are engaged with the bottom surface of the assembly groove, and one side of the main reed 1 and the auxiliary reed 2 is engaged with the straight wall. The aforementioned pressure block 4 has an inclined surface and is installed between the other side of the main reed 1 and the auxiliary reed 2 and the inclined wall. The slope of the inclined wall is adapted to the slope of the pressure block 4, so that during the installation process, the pressure block 4 can continuously press the main reed 1 and the auxiliary reed 2 until they are tightly engaged with the straight wall of the assembly groove.

[0028] The height of the pressure block 4 is set to be the same as the height of the assembly groove. After the pressure block 4 is installed, the top surface of the pressure block 4 is flush with the upper end surface of the assembly groove.

[0029] Furthermore, a pressure plate 5 is provided at the upper end of the pressure block 4 and the assembly groove. The pressure plate 5 is provided with multiple connecting holes 51. Correspondingly, the pressure block 4 is provided with a through connecting hole 41. The upper end and bottom surface of the assembly groove are provided with connecting holes 31 and 32, respectively. The pressure block 4 can be fixed by multiple bolts passing through the connecting holes 51, 31, 51, 41, and 32, so that the main reed 1 and the auxiliary reed 2 are tightly engaged with the straight wall of the assembly groove, preventing the main reed 1 and the auxiliary reed 2 from moving relative to the reed seat 3, thereby ensuring the quality of each weft insertion.

[0030] Please see Figure 2 , Figure 4 and Figure 5 The main reed 1 and the secondary reed 2 are detachably fitted together. Specifically, the right end of the main reed 1 and the left end of the secondary reed 2 ( Figure 2 The cutting is performed in the direction of the main reed 1. A first protrusion 11 and a first groove 12 are provided on the cutting surface of the main reed 1, and a second groove 22 and a second protrusion 21 are provided on the cutting surface of the secondary reed 2. In the assembled state, the two cutting surfaces are joined together, and the thickness of the joint is the same as the thickness of the main reed 1 and the secondary reed 2, which facilitates the fixing of the pressure block 4.

[0031] The first protrusion 11 and the first groove 12 of the main reed 1 respectively mate with the second groove 22 and the second protrusion 21 to achieve a fitted connection. Connecting holes 13 and 23 can be respectively opened on the cutting surfaces of the main reed 1 and the secondary reed 2. Bolts are passed through these connecting holes 13 and 23 to further secure the main reed 1 and the secondary reed 2 on top of the fixing by the pressure block 4.

[0032] The aforementioned weft detector can be installed on the secondary reed 2, and the yarn for the offset can be threaded through the secondary reed 2. When the fabric width increases, first remove the pressure plate 5 and pressure block 4, and separate the main reed 1 and secondary reed 2. Without disassembling the weft detector or re-threading the yarn for the offset, simply connect the replaced, wider main reed 1 to the secondary reed 2, and then install the pressure block 4 and pressure plate 5. In other words, this eliminates the need to disassemble the weft detector and re-thread the yarn for the offset, thus significantly improving work efficiency.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention 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; and these 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 the present invention.
