Description

Technical Field

[0001] This utility model relates to the field of circular loom technology, specifically to a yarn conveying mechanism for a circular loom. Background Technology

[0002] Most existing circular loom workshops are two-story buildings, with the ground floor used to house the yarn rack and the second floor to house the circular loom, requiring a large and tall workshop space. Circular looms require a conveying mechanism for yarn transport and positioning during operation. However, ordinary conveying mechanisms are complex in structure, requiring holes to be drilled in them. During the initial threading, each yarn must be threaded through the positioning holes one by one, resulting in slow yarn handling and wasting a significant amount of manpower and time. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a yarn conveying mechanism for a circular loom. The mechanism has a simple structure, which makes the initial yarn handling more convenient, speeds up the initial yarn threading, and improves the production speed. It can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a yarn conveying mechanism for a circular loom, comprising a base, two vertical side plates fixed on the upper surface of the base, the two vertical side plates being located on the front and rear sides of the middle of the base, two sets of vertically distributed support rollers being arranged between the two vertical side plates, and two yarn positioning components being arranged on the upper surface of the base, the yarn positioning components being located at both ends of the vertical side plates, and universal guide wheels being arranged at the four corners of the lower surface of the base;

[0005] The yarn positioning component includes two vertical foot plates fixed to the upper surface of the base. Two lower limit components are provided between the two vertical foot plates. The two lower limit components correspond to the upper and lower sets of support rollers. Two upper and lower drive components are fixed to the upper surface of the base. Two upper limit plates are fixed between the two upper and lower drive components. The two upper limit plates correspond to the two lower limit components respectively. The upper surface of the lower limit component has a groove in the middle for the lower end of the upper limit plate to be inserted. When the lower end of the upper limit plate is inserted into the groove of the lower limit component, the yarn can be positioned.

[0006] Furthermore, each set of support rollers has no fewer than three rollers, which are evenly arranged in the horizontal direction. The outer side of the support rollers is evenly provided with annular yarn positioning grooves, and the cross-section of the yarn positioning grooves is V-shaped.

[0007] Furthermore, on the opposite side of the lower limiting member and the upper limiting plate, corresponding yarn clamping grooves are uniformly provided, and the yarn clamping grooves on the lower limiting member and the yarn clamping grooves on the upper limiting plate form limiting holes.

[0008] Furthermore, the up-and-down driving assembly includes a support fixed to one side of the base. A hydraulic telescopic column is fixed to the upper surface of the support, and a support frame is fixedly installed at the upper end of the hydraulic telescopic column. The extension and retraction of the hydraulic telescopic column can drive the support frame to move up and down. The support frame can drive the upper limit plate to move upward. During the first batch of threading, the upper limit plate is moved upward by the hydraulic telescopic column, which increases the gap between the lower limit member and the upper limit plate. After the yarn passes through, the gap between the lower limit member and the upper limit plate closes, so that the yarn is inside the limiting hole formed by the yarn clamping groove, thereby facilitating the first batch of threading.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the hydraulic telescopic column can drive the support frame to move up and down, and the support frame can drive the upper limit plate to move upward. During the first batch of yarn threading, the hydraulic telescopic column drives the upper limit plate to move upward, which increases the gap between the lower limit piece and the upper limit plate. After the yarn passes through, the lower limit piece and the upper limit plate close together, so that the yarn is inside the limiting hole formed by the yarn clamping groove. This facilitates the first batch of yarn threading. This circular loom yarn conveying mechanism has a simple structure, which makes the first yarn handling more convenient, speeds up the first threading, and improves the production speed.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4This utility model provides a technical solution: a yarn conveying mechanism for a circular loom, including a base 1, two vertical side plates 3 fixed on the upper surface of the base 1, the two vertical side plates 3 being located on the front and rear sides of the middle of the base 1, two sets of vertically distributed support rollers 4 being arranged between the two vertical side plates 3, and two yarn positioning components being arranged on the upper surface of the base 1, the yarn positioning components being located at both ends of the vertical side plates 3, and universal guide wheels 8 being arranged at the four corners of the lower surface of the base 1;

[0017] The yarn positioning component includes two vertical foot plates 7 fixed to the upper surface of the base 1. Two lower limit members 6 are provided between the two vertical foot plates 7, corresponding to the upper and lower sets of support rollers 4. Two upper and lower drive assemblies 2 are fixed to the upper surface of the base 1, and two upper limit plates 5 are fixed between the two upper and lower drive assemblies 2. The two upper limit plates 5 correspond to the two lower limit members 6 respectively, and the upper surface of the lower limit member 6 has a groove in the middle for the lower end of the upper limit plate 5 to be inserted. When the lower end of the upper limit plate 5 is inserted into the groove of the lower limit member 6, it can position the yarn. Each set of support rollers 4 has no fewer than three rollers, evenly arranged in the horizontal direction. A ring-shaped yarn positioning groove is evenly arranged on the outer side of the support roller 4. The yarn positioning groove has a V-shaped cross-section, and the bottom of the yarn positioning groove has a rounded chamfer to prevent clamping the yarn. Corresponding yarn clamping grooves are evenly arranged on the opposite side of the lower limit member 6 and the upper limit plate 5. The yarn receiving groove and the yarn receiving groove on the upper limit plate 5 form a limiting hole, and the front and rear sides of the yarn receiving groove are rounded to prevent the yarn from being worn off. The upper and lower drive assembly 2 includes a support 23 fixed to one side of the base 1. A hydraulic telescopic column 22 is fixed on the upper surface of the support 23. A support frame 21 is fixedly installed at the upper end of the hydraulic telescopic column 22. The extension and retraction of the hydraulic telescopic column 22 can drive the support frame 21 to move up and down. The support frame 21 can drive the upper limit plate 5 to move up and down. When threading yarn in a large batch for the first time, the upper limit plate 5 is moved up by the hydraulic telescopic column 22, which makes the gap between the lower limit piece 6 and the upper limit plate 5 larger. After the yarn passes through, the gap between the lower limit piece 6 and the upper limit plate 5 closes, so that the yarn is inside the limiting hole formed by the yarn receiving groove. This facilitates the threading of yarn in a large batch for the first time. This circular loom yarn conveying mechanism has a simple structure, which makes the initial yarn handling more convenient, speeds up the initial threading, and improves the production speed.

[0018] In use: The hydraulic telescopic column 22 can extend and retract to drive the support frame 21 to move up and down. The support frame 21 can then drive the upper limit plate 5 to move upward. During the first batch of threading, the hydraulic telescopic column 22 drives the upper limit plate 5 to move upward, which increases the gap between the lower limit piece 6 and the upper limit plate 5. After the yarn passes through, the gap between the lower limit piece 6 and the upper limit plate 5 closes, causing the yarn to be inside the limiting hole formed by the yarn clamping groove. This facilitates the first batch of threading and can also support the support roller 4 during the conveying process.

[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
