Description

Technical Field

[0001] This utility model relates to the field of woven bag production technology, and in particular to an adjustable feeding spindle. Background Technology

[0002] In the traditional production and processing of woven bags, the main steps to form a single woven bag include the proportioning and mixing of raw materials, drawing, weaving, coating, cutting, printing and sewing. In the weaving process, the weaving is generally carried out by continuously feeding materials through a feeding spindle.

[0003] In the existing technology, the spacing between the shaft edges of the feeding spindle is uniform. When it is necessary to speed up the weaving speed of the machine during production, a feeding spindle with a narrower shaft edge spacing is often used to speed up the feeding speed and ensure continuous material supply. Since the shaft edges of the feeding spindle are fixed and cannot be adjusted, multiple feeding spindles with different shaft edge spacings are usually required to cooperate with production, which increases material costs.

Detailed Implementation

[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Please see Figures 1-3In this embodiment of the present invention, an adjustable feeding spindle is provided. The spindle includes a shaft column 1, a bushing 2, and a shaft cover 3. The shaft column 1 has a positioning ridge 11 for positioning the bushing 2 on its axial surface. The positioning ridge 11 is arranged in the radial direction of the shaft column 1 such that the positioning ridge 11 is perpendicular to the cross-section of the shaft column 1. The bushing 2 has a positioning groove 21 inside it. The bushing 2 is sleeved on the shaft column 1. The positioning ridge 11 is inserted into the positioning groove 21 to restrict the bushing 2 from rotating on the shaft column 1. The shaft surface of the bushing 2 has a shaft ridge 22. The shaft cover 3 is detachably installed at both ends of the shaft column 1.

[0029] The working principle of this embodiment is as follows: During the production and processing of woven bags, if the operator needs to adjust the weaving speed of the weaving machine, the conveying speed of the feeding spindle needs to be changed simultaneously. The operator can replace the bushings 2 with different shaft edge spacing to achieve the conveying speed of the feeding spindle. The operator can first remove the shaft cover 3 so that the bushing 2 can be pulled out from the direction of the removed shaft cover 3, and then put the bushings 2 with different shaft edge spacing onto the shaft post 1. The shaft post 1 is provided with positioning ridges 11 for positioning the bushing 2. When installing the bushing 2, the operator can align the positioning groove 21 on the bushing 2 with the positioning ridge 11 and insert it to prevent the bushing 2 from rotating at the shaft post 1.

[0030] Further as Figures 1-2 As shown in the embodiment of this utility model, the bushing 2 includes a first bushing 23a and a second bushing 23b for replacing the shaft post 1. The first bushing 23a has a first shaft ridge 22 with a wider shaft ridge spacing on its shaft surface, and the second bushing 23b has a second shaft ridge 22 with a narrower shaft ridge spacing on its shaft surface.

[0031] The working principle of this embodiment is as follows: When the operator adjusts the braiding machine to use a slower braiding speed, a feeding spindle with a wider shaft edge spacing is required. When replacing the bushing 2 of the feeding spindle, the operator can install the first bushing 23a on the shaft post 1 to match the braiding speed of the braiding machine. When the braiding speed of the braiding machine increases, the shaft cover 3 can be removed first, so that the first bushing 23a can be pulled out from the direction of the removed shaft cover 3. Then, the positioning groove 21 in the second bushing 23b is aligned with the positioning edge 11 on the shaft post 1. Subsequently, the second bushing 23b is inserted into the shaft post 1, and the previously removed shaft cover 3 is installed back onto the shaft post 1. At this time, the assembly of the second bushing 23b and the shaft post 1 is completed. The narrower shaft edge 22 of the second shaft post 1 can provide a faster conveying speed during feeding to adapt to the faster braiding speed of the braiding machine.

[0032] Further as Figures 1-2 As shown in the embodiment of this utility model, the axial surface dimension of the shaft cover 3 is not less than the axial surface dimension of the shaft post 1. The shaft cover 3 is installed at both ends of the shaft post 1 and can be used to fix the shaft sleeve 2 so that it is locked on the shaft post 1.

[0033] Further as Figure 3As shown in the embodiment of this utility model, the two ends of the shaft post 1 are provided with first threads 12, and one end of the shaft cover 3 is provided with a threaded hole. The first threads 12 of the shaft post 1 correspond to the threaded hole of the shaft cover 3. The two ends of the shaft post 1 are respectively threaded to the shaft cover 3. The connection method between the shaft cover 3 and the shaft post 1 includes, but is not limited to, threaded connection, and can also be achieved through tenon and mortise connection or adhesive connection.

[0034] Further as Figure 3 As shown in the embodiment of this utility model, the shaft 1 includes a connecting shaft 13 and a connecting cylinder 14. The two ends of the connecting shaft 13 are provided with a first thread 12, and the inner wall of the connecting cylinder 14 is provided with an internal thread. The internal thread corresponds to the first thread 12. The positioning ridge 11 is provided on the axial surface of the connecting shaft 13 such that the positioning ridge 11 is perpendicular to the cross-section of the connecting shaft 13.

[0035] The working principle of this embodiment is as follows: the connecting shaft 13 and the connecting cylinder 14 can be set in multiple sections, and shaft columns 1 of different lengths can be installed. Specifically, the connecting shaft 13 is threaded to both sides of the connecting cylinder 14 to form a shaft column 1. The above steps can be repeated to form multiple shaft columns 1. Then, the connecting cylinder 14 is set between each shaft column 1 to connect the multiple shaft columns 1 together.

[0036] Further, such as Figure 3 As shown, the connecting shaft 13 includes a first connecting shaft 13a, a second connecting shaft 13b, and a third connecting shaft 13c. The connection sequence from left to right is as follows: one end of the first connecting shaft 13a is threaded to one end of the first connecting cylinder 14; the other end of the first connecting cylinder 14 is threaded to one end of the second connecting shaft 13b; the other end of the second connecting shaft 13b is threaded to one end of the second connecting cylinder 14; and the other end of the second connecting cylinder 14 is threaded to one end of the third connecting shaft 13c. By repeating the above steps, shafts 1 of different lengths can be assembled, so that the feeding spindle can adapt to different feeding lengths.

[0037] Further as Figure 1 and Figures 4-7As shown in this embodiment of the present invention, the feeding spindle further includes a hinge block 4 and a connecting block 5. One end of the hinge block 4 is detachably connected to the left side of the shaft column 1, and one end of the connecting block 5 is detachably connected to the right side of the shaft column 1. The hinge block 4 includes a first base 41, a first hinge shaft 42, and a first locking cover 43. The first base 41 has a first groove 411, and the first groove 411 has a first through hole 412. The first hinge shaft 42 has a hinge end 421 that hinges to the first through hole 412. The right side of the first hinge shaft 42 is rotatably connected to the shaft column 1. On the left side, the first locking cover 43 is detachably installed on the upper end of the first base 41 to restrict the rotation of the hinge shaft. The connecting block 5 includes a second base 51, a second hinge shaft 52, and a second locking cover 53. The second base 51 has a second groove 511, and a second through groove 512 is provided on the groove surface of the second groove 511. The second hinge shaft 52 has an extension end 521 that is movably installed in the second through groove 512. The left side of the second hinge shaft 52 is rotatably connected to the right side of the shaft post 1. The second locking cover 53 is detachably installed on the upper end of the second base 51.

[0038] The working principle of this embodiment is as follows: When the operator needs to replace the bushing 2 to adapt to different weaving speeds, firstly, the first locking cover 43 and the second locking cover 53 are disassembled, so that the rotating column can be rotated upward with the first through hole 412 as the axis. The bushing cover 3 at the end of the rotating column facing the connecting block 5 is disassembled, so that the bushing 2 to be replaced can be taken out from this direction. After taking out the bushing 2 to be replaced, the bushing 2 with a suitable shaft edge spacing is inserted into the shaft column 1 from this direction. The bushing cover 3 is then installed to complete the replacement of the bushing 2. Then, the shaft column 1 is rotated downward to reset the second hinge shaft 52 to the second through groove 512. The first locking cover 43 is then installed on the original first base 41, and the second locking cover 53 is installed on the original second base 51, thereby completing the replacement of the bushing 2. By setting the hinge block 4 and the connecting block 5, the feeding spindle is made more convenient and faster to replace the bushing 2, which is conducive to improving production efficiency.
