Description

Technical Field

[0001] This utility model relates to the field of weaving machine technology, specifically to a weaving machine pressing wheel. Background Technology

[0002] Looms, also known as spinning machines, weaving machines, cotton spinning machines, etc., were all early human-powered looms. Traditionally, looms that use yarn for weaving can be divided into two main categories: machine-woven looms and knitting looms. Machine-woven looms include the primitive shuttle looms and the newer shuttleless looms. Shuttleless looms mainly include rapier looms, air-jet looms, water-jet looms, and rapier looms. Knitting machines are divided into two main categories: warp knitting and weft knitting, with many subcategories within each category.

[0003] Currently, existing loom pressing wheels are connected to the shaft by multiple sets of bolts and nuts. Because the bolts are prone to loosening and causing the connection to detach, and disassembly and maintenance are extremely cumbersome and inconvenient, resulting in low work efficiency and greatly affecting the performance.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model provides, for example Figures 1-4 A pressing roller for a loom, as shown, includes:

[0025] Pressing wheel body 1;

[0026] The two ends of the pressing wheel body 1 are symmetrically provided with bosses 5. One end of the bosses 5 is detachably connected to a fixing cylinder 6. The fixing cylinder 6 is provided with a connecting shaft 7 at one end relative to the bosses 5.

[0027] A rubber sleeve 2 is provided on the outer wall of the pressure roller body 1. Based on this, the elasticity of the rubber sleeve 2 can prevent damage to the yarn.

[0028] Retaining rings 3 are symmetrically arranged on both sides of the outer wall of the rubber sleeve 2. Based on this, the retaining rings 3 can prevent the yarn from detaching from the pressure roller body 1.

[0029] The two ends of the pressing wheel body 1 are symmetrically provided with annular grooves 4, and the annular grooves 4 are located between the rubber sleeve 2 and the boss 5.

[0030] The side wall of the boss 5 has a slot 8 facing the fixed cylinder 6 in the middle, and the side wall of the boss 5 has a plurality of slots 9 arranged in a ring array with the slot 8 as the center. One end of the fixed cylinder 6 can be inserted into the slot 8, and the end of the fixed cylinder 6 inserted into the slot 8 has a plurality of locking posts 10 arranged in a ring array. The locking posts 10 can be inserted into the slots 9, and a locking component is provided between the locking posts 10 and the boss 5. A telescopic component is provided between the fixed cylinder 6 and the connecting shaft 7.

[0031] The telescopic assembly includes a first cavity 11 located inside the fixed cylinder 6 at one end relative to the locking post 10. A first spring 12 is fixed inside the first cavity 11 at one end. One end of the connecting shaft 7 extends into the first cavity 11 and is fixedly connected to the first spring 12.

[0032] The locking assembly includes a second cavity 15 disposed within the locking post 10. A second spring 16 is fixed to one end of the interior of the second cavity 15. A slider 17 is connected to one end of the second spring 16. A positioning post 13 is fixed to one end of the slider 17 relative to the second spring 16. One end of the positioning post 13 extends to the outside of the locking post 10. Multiple positioning holes 14 communicating with the locking groove 9 are arranged in a ring array on the outer side of the boss 5, and the positioning post 13 can be inserted and fitted into the positioning holes 14.

[0033] By inserting the end of the fixed cylinder 6 into the slot 8, and embedding multiple sets of locking pins 10 arranged in a ring array into the slot 9, and by inserting multiple sets of positioning pins 13 into each positioning hole 14 respectively, the fixed cylinder 6 can be locked onto the boss 5, and the connecting shaft 7 can be connected to the pressure wheel body 1.

[0034] During disassembly, each positioning post 13 is pressed with a tool, causing the positioning post 13 to squeeze the second spring 16 through the slider 17. Then, the positioning post 13 can retract and exit the positioning hole 14. After that, the fixing cylinder 6 is pulled, which can drive the first spring 12 to retract and move at the end of the connecting shaft 7. This allows the fixing cylinder 6 to drive multiple sets of locking posts 10 to exit the slot 8 and slot 9 respectively, thus quickly separating the fixing cylinder 6 from the boss 5. Then, the pressing wheel body 1 can be removed from the connecting shaft 7. The operation is simple and convenient, and the connection is stable and reliable, with good performance.
