Description

Technical Field

[0001] This utility model relates to a loom, specifically to an extended weft insertion shaft structure for a loom and an extended wide-width loom including the same. Background Technology

[0002] Chinese patent application CN201320834521.8 discloses a double conjugate cam beat-up mechanism for a loom. The double conjugate cam beat-up mechanism for a loom includes a reed seat, a beat-up shaft, and a rotating shaft. The reed seat is connected to the beat-up shaft via a support. A steel reed is provided on the reed seat. Both ends of the rotating shaft are connected to gear shafts. A transmission gear is provided above the gear shaft and meshes with the teeth of the gear shaft. A conjugate cam is connected to the transmission gear. Both ends of the beat-up shaft are connected to swing shafts corresponding to the transmission gears, and the swing shafts are connected to the transmission gears.

[0003] Although the double conjugate cam beat-up mechanism for looms achieves the transmission connection between the gear shaft and the beat-up shaft through the transmission gear and the conjugate cam, the double conjugate cam beat-up mechanism for looms still has the following drawbacks: the reed supports both ends of the beat-up shaft, and when the beat-up shaft is too long, the middle of the beat-up shaft is stressed during operation, and the beat-up shaft is prone to breakage. Therefore, how to increase the length of the beat-up shaft while ensuring the strength of the middle part of the beat-up shaft is an urgent problem to be solved. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model first discloses an extended weft insertion shaft structure for a loom, comprising: a first weft shaft body, a second weft shaft body, a frame, a support mechanism, and a connecting mechanism; the support mechanism is installed on the frame, the support mechanism supports the first end of the first weft shaft body, the second end of the first weft shaft body is supported by the frame, the support mechanism supports the first end of the second weft shaft body, the second end of the second weft shaft body is supported by the frame, both the first and second weft shaft bodies can rotate relative to the frame and the support mechanism; the center lines of the first and second weft shaft bodies are on a straight line, and the first and second weft shaft bodies are connected by a connecting mechanism.

[0007] Preferably, the support mechanism includes: a support base, a support ring, and a support bearing. The support base is equipped with a support ring and a support bearing on both sides. The support ring extends into the support base, and the support bearing extends into the support ring. The support bearing is used to support the first end of the first weft axis or the first end of the second weft axis.

[0008] Preferably, the connecting mechanism includes: a gear ring, a mounting plate fixed to the first end of the first weft shaft and the first end of the second weft shaft, the mounting plate protruding to form a rotating shaft, the rotating shaft being rotatably supported by a support mechanism, a gear extending from the side of the rotating shaft away from the mounting plate, the gear on the first weft shaft and the gear on the second weft shaft both extending into the gear ring.

[0009] Preferably, both the first end of the first weft axis body and the first end of the second weft axis body form a mounting head. The mounting head includes a first fixing plate, an intermediate plate, and a second fixing plate. The first fixing plate is connected to the first end of the first weft axis body or the first end of the second weft axis body. The first fixing plate is connected to the second fixing plate through the intermediate plate. The outer diameter of the intermediate plate is smaller than the outer diameter of the first fixing plate and the outer diameter of the second fixing plate. The mounting plate is mounted on the second fixing plate.

[0010] Preferably, the support base has an installation cavity, in which gears and gear rings are installed, and the installation cavity is closed by a cover.

[0011] Preferably, the outer wall of the support ring protrudes to form a fixing ring, and the fixing ring is mounted on the support base.

[0012] Preferably, the end of the support ring that extends into the mounting cavity extends to form a conical ring, the large end of the conical ring is fixed to the support ring, the small end of the conical ring extends into the end of the toothed ring, and the toothed ring is clamped by the conical rings on both sides.

[0013] Preferably, the tapered bearing is clamped between the outer wall of the tapered ring and the inner wall of the toothed ring end.

[0014] This utility model also discloses an extended wide-width loom, including: the extended beat-up beam structure of the loom as described above.

[0015] Preferably, the extended wide-width loom further includes: a first drive shaft, a second drive shaft, an intermediate connecting shaft, a first shaft connecting mechanism, and a second shaft connecting mechanism.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this application, the beat-up beam is divided into a first beat-up beam body and a second beat-up beam body, effectively splitting the original single beat-up beam into two sections. This lengthens the beat-up beam, which is further supported by a central support mechanism. This ensures support in the middle section when the beat-up beam is under stress during operation. The first ends of both the first and second beat-up beam bodies are located at the middle of the beat-up beam, preventing breakage due to lack of support in the middle. This achieves the goal of both maintaining the strength of the beat-up beam composed of the first and second beat-up beam bodies and extending its overall length. Increasing the length of the beat-up beam also increases the overall length of the loom, thereby widening the fabric width, improving production efficiency, and ensuring the lifespan of the beat-up beam.

[0018] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

Detailed Implementation

[0025] To make the technical means, creative features, achieved objectives and functions of this utility model clearer and easier to understand, the utility model will be further described below with reference to the accompanying drawings and specific embodiments:

[0026] Example 1:

[0027] like Figures 1 to 4 As shown, this embodiment discloses an extended weft bead structure for a loom, including: a first weft bead body 1, a second weft bead body 2, a frame 3, a support mechanism 4, and a connecting mechanism 5; the support mechanism 4 is installed on the frame 3, the support mechanism 4 supports the first end of the first weft bead body 1, the second end of the first weft bead body 1 is supported by the frame 3, the support mechanism 4 supports the first end of the second weft bead body 2, the second end of the second weft bead body 2 is supported by the frame 3, both the first weft bead body 1 and the second weft bead body 2 can rotate relative to the frame 3 and the support mechanism 4; the centerline of the first weft bead body 1 and the centerline of the second weft bead body 2 are on a straight line, and the first weft bead body 1 and the second weft bead body 2 are connected by the connecting mechanism 5.

[0028] The support mechanism 4 includes a support base 40, a support ring 41, and a support bearing 42. Support rings 41 and support bearings 42 are installed on both sides of the support base 40. The support rings 41 extend into the support base 40, and the support bearings 42 extend into the support rings 41. The support bearings 42 support the first end of the first weft axis 1 or the first end of the second weft axis 2. This achieves support for the first end of the first weft axis 1 or the first end of the second weft axis 2, and ensures that both the first ends of the first weft axis 1 and the first ends of the second weft axis 2 can rotate smoothly relative to the support mechanism 4.

[0029] The connecting mechanism 5 includes a gear ring 51. Mounting discs 11 are fixed to the first end of the first weft shaft 1 and the first end of the second weft shaft 2. The mounting discs 11 protrude to form a rotating shaft, which is rotatably supported by a support mechanism 4. A gear 13 extends from the side of the rotating shaft away from the mounting discs 11. Both the gear 13 on the first weft shaft 1 and the gear 13 on the second weft shaft 2 extend into the gear ring 51. Gears 13 are fixed to the first end of the first weft shaft 1 and the first end of the second weft shaft 2, and the gear ring 51 meshes with the gears 13, enabling the first weft shaft 1 and the second weft shaft 2 to rotate together.

[0030] Mounting heads 14 are formed at the first end of the first weft shaft 1 and the first end of the second weft shaft 2. Each mounting head 14 includes a first fixing plate 141, an intermediate plate 142, and a second fixing plate 143. The first fixing plate 141 is connected to the first end of either the first weft shaft 1 or the first end of the second weft shaft 2. The first fixing plate 141 is connected to the second fixing plate 143 via the intermediate plate 142. The outer diameter of the intermediate plate 142 is smaller than the outer diameter of the first fixing plate 141 and the outer diameter of the second fixing plate 143. Mounting plates 11 are mounted on the second fixing plate 143. The structural design of the mounting head 14 allows for threaded holes to be drilled in the second fixing plate 143, facilitating the installation of the mounting plate 11 and the gear 13. The mounting plate 11 and the gear 13 are integrally formed in a mold.

[0031] The support base 40 has an installation cavity, in which the gear 13 and the gear ring 51 are installed. The installation cavity is sealed by a cover 400. The installation of the gear 13 and the gear ring 51 inside the installation cavity prevents external impurities from entering.

[0032] The outer wall of the support ring 41 protrudes to form a fixing ring 410, which is mounted on the support base 40. This allows the support ring 41 to be mounted on the support base 40 via the fixing ring 410.

[0033] Example 2:

[0034] The difference between this embodiment and embodiment 1 is that a conical ring 411 and a conical bearing 52 are added, while other structures remain unchanged.

[0035] like Figure 4 as well as Figure 5 As shown, the end of the support ring 41 that extends into the mounting cavity extends to form a conical ring 411. The large end of the conical ring 411 is fixed to the support ring 41, and the small end of the conical ring 411 extends into the end of the gear ring 51. The gear ring 51 is clamped by the two conical rings 411. This achieves the positioning of the gear ring 51 by the two conical rings 411, and at the same time, the conical ring 411 has the function of guiding the rotation of the gear ring 51. The conical ring 411, the support ring 41, and the fixing ring 410 are integrally formed in the mold. When installing the support ring 41, the conical ring 411 can be installed at the same time, reducing the installation steps of the conical ring 411 and improving production and installation efficiency. When installing the support ring 41, the conical ring 411 is pushed inward, and then the two conical rings 411 clamp the gear ring 51, thereby positioning the support gear ring 51 and avoiding excessive oscillation at the gear 13 due to the lack of support and guidance for the gear ring 51, thus reducing abnormal noise.

[0036] A tapered bearing 52 is clamped between the outer wall of the tapered ring 411 and the inner wall of the end of the toothed ring 51. This makes the rotation of the toothed ring 51 relative to the tapered ring 411 smoother.

[0037] Example 3:

[0038] This embodiment discloses an extended wide-width loom, including: an extended beat-up beam structure as described in Embodiment 1 or Embodiment 2.

[0039] The extended wide-width loom further includes: a first drive shaft 61, a second drive shaft 62, an intermediate connecting shaft 63, a first shaft connecting mechanism (not shown in the figure), and a second shaft connecting mechanism (not shown in the figure). The first end of the first drive shaft 61 is rotatably mounted on the frame 3. The second end of the first drive shaft 61 is fixed to one end of the intermediate connecting shaft 63 via the first shaft connecting mechanism. The intermediate connecting shaft 63 is rotatably mounted on the support mechanism 4. The other end of the intermediate connecting shaft 63 is fixed to the second end of the second drive shaft 62 via the second shaft connecting mechanism. The first end of the second drive shaft 62 is rotatably mounted on the frame 3. By extending the beating shaft, the length of the total drive shaft formed by the first drive shaft 61 and the second drive shaft 62 is also extended, ensuring that the middle of the total drive shaft is also supported.

[0040] 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 this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
