Description

Technical Field

[0001] This utility model relates to the field of large circular knitting machine technology, and in particular to a novel syringe holder structure. Background Technology

[0002] In circular knitting machines and other similar equipment, the cylinder is the core component that carries the knitting needles, and it is fixed to the machine via a cylinder holder. To ensure smooth needle movement, a continuous supply of lubricating oil is required to the cylinder. However, the existing cylinder holder structure has significant drawbacks: First, due to limitations in manufacturing precision, there are minute gaps between the mating surfaces of the syringe and the syringe base, resulting in poor sealing. Lubricating oil seeps out from these gaps and flows along the surface of the syringe base into the screw mounting holes used to secure the syringe. Although some structures use sealing gaskets for sealing, these gaskets are prone to aging or compression deformation after prolonged use, leading to seal failure. The accumulated lubricating oil eventually penetrates the sealing gasket and drips onto the fabric being woven below, forming oil stains (i.e., "oily cloth" or "dirty cloth"), severely affecting fabric quality and product grade. Secondly, traditional syringe holder structures lack effective fine-tuning capabilities. The horizontality (i.e., parallelism in the height direction) and concentricity with the syringe holder during installation depend entirely on the machining accuracy of the parts themselves. If the accuracy is out of tolerance, it is impossible to effectively compensate on-site, resulting in unstable syringe operation, affecting knitting quality. Moreover, the adjustment process is cumbersome, requiring replacement or regrinding of parts, which is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this invention is to provide a novel syringe holder structure to solve the above-mentioned problems.

[0004] The technical solution of this utility model is implemented as follows: This utility model provides a novel syringe holder structure, including a large plate, a syringe holder and a syringe. The syringe holder is mounted on the large plate, the syringe is mounted on the syringe holder, and the syringe holder is equipped with a syringe height adjustment mechanism and a syringe positioning mechanism. The syringe height adjustment mechanism includes a set screw, a first fixing bolt, and a lock nut. The set screw passes through the lock nut and is threaded onto the syringe base, with the top of the set screw fitting against the bottom surface of the syringe. The first fixing bolt is threaded onto the syringe base, and the syringe has a threaded hole for connection with the first fixing bolt. The syringe positioning mechanism includes a positioning block, a second fixing bolt, and a positioning bolt. The positioning block is attached to the syringe base. The second fixing bolt passes through the positioning block and is threadedly connected to the syringe base. The second fixing bolt and the positioning block are threadedly connected. The positioning bolt is threadedly connected to the positioning block, and one side of the positioning bolt is attached to the inner wall of the syringe. The syringe has a groove at the bottom and a protrusion embedded in the groove on the syringe base. The width of the groove is greater than the width of the protrusion. The syringe base is also provided with an oil guide groove that surrounds the syringe base and has a diameter smaller than the diameter of the protrusion.

[0005] In one embodiment, both the set screw and the first fixing bolt have internal hexagonal sockets on their heads. This design allows for operation with a standard hexagonal wrench, providing a large contact area, even force application, and reduced slippage, making it particularly suitable for space-constrained installation environments. This greatly facilitates the disassembly and adjustment of the mechanism, improves maintenance efficiency, and avoids the risk of stripping threads that may occur when using a screwdriver.

[0006] In one embodiment, the syringe height adjustment mechanism comprises multiple components, evenly distributed on the syringe base. This technical solution, through multi-point uniform adjustment, allows for more precise and stable correction of the syringe's levelness. The stress generated at a single adjustment point is relatively small, avoiding the problem of excessive force at a single point leading to syringe deformation or inaccurate adjustment, ensuring the overall flatness of the syringe mounting surface, and thus guaranteeing the stability of the syringe's operation.

[0007] In one embodiment, each syringe height adjustment mechanism is equipped with two set screws and one first fixing bolt. This technical solution adopts a "two-top-one-bolt" configuration, where the two set screws are responsible for precise local height adjustment, and the first fixing bolt is responsible for final tightening. This clearly defined structure ensures that the leveling and tightening operations do not interfere with each other. Fine adjustment is performed before tightening, guaranteeing that the adjustment accuracy is not lost during the tightening process, making the structure more scientific and reasonable.

[0008] In one embodiment, an oil storage tank is connected to the bottom of the oil guide groove. This design uses the oil guide groove to intercept and collect leaked lubricating oil, while the oil storage tank provides a dedicated space to temporarily store a certain amount of waste oil. This complete "guide-collection" system prevents lubricating oil from flowing disorderly across the syringe holder surface or overflowing from the oil guide groove, achieving controllable management of leaked lubricating oil. Only periodic cleaning of the oil storage tank is required, greatly improving the cleanliness and ease of maintenance of the equipment.

[0009] In one embodiment, the syringe positioning mechanism comprises a plurality of components, evenly distributed on the syringe base. This design allows multiple positioning mechanisms to apply forces to the inner wall of the syringe from different directions, effectively correcting the radial runout of the syringe and ensuring its concentricity with the syringe base. The even distribution balances the corrective forces, preventing the syringe from tilting during adjustment and improving the accuracy and reliability of the adjustment.

[0010] In one embodiment, each syringe positioning mechanism is provided with two second fixing bolts and one positioning bolt. This technical solution adopts a "two-adjustment-one-fixation" configuration. The two second fixing bolts can firmly press the positioning block onto the syringe seat, ensuring the stability of the positioning block as an adjustment base. The positioning bolt is dedicated to radial fine adjustment. This structure ensures that the positioning block itself will not shift during concentricity adjustment, making the adjustment action more precise and effective.

[0011] In one embodiment, the first fixing bolt is provided with an anti-slip pad, which is located between the fixing bolt and the syringe seat.

[0012] Compared with the prior art, the technical solution provided by this utility model has the following significant advantages: 1. Highly efficient oil leak prevention: Through a labyrinthine "groove-protrusion" initial seal, combined with an annular oil guide groove located inside the protrusion, the flow direction of leaking lubricating oil is effectively changed, guiding it to a predetermined collection point. Together with an oil storage tank, this forms an active oil leak prevention system, fundamentally solving the industry problem of lubricating oil contaminating fabric surfaces. 2. Precisely Adjustable: Independently designed height and concentricity adjustment mechanisms allow for fine-tuning of the syringe's axial and radial positions, respectively. Simple screwing operations can compensate for machining errors, enabling rapid installation with high horizontality and concentricity of the syringe. This reduces reliance on absolute machining precision and improves assembly efficiency and quality. 3. Stable and reliable structure: Multiple adjustment and positioning mechanisms are evenly distributed, the design of separating the "adjustment" and "tightening" functions, and details such as the internal hexagon drive, so that the entire structure has high rigidity and stability while ensuring the adjustment function, ensuring that the syringe remains in a precise position even when running at high speed. 4. Easy Maintenance: The oil guide groove and oil storage tank facilitate waste oil collection and disposal; the internal hexagonal hole design simplifies assembly, disassembly, and debugging. The overall structure facilitates daily maintenance and upkeep, reducing the cost of equipment use and maintenance. Attached Figure Description

[0021] Reference Figures 1-8 A novel syringe holder structure includes a large plate 7, a syringe holder 1, and a syringe 2. The syringe holder 1 is mounted on the large plate 7, and the syringe 2 is mounted on the syringe holder 1. The syringe holder 1 is equipped with a syringe height adjustment mechanism 3 and a syringe positioning mechanism 4.

[0022] like Figure 7 As shown, the syringe height adjustment mechanism 3 penetrates the syringe base 1. During installation, first screw the anti-loosening nut 33 onto the set screw 31, then screw the set screw 31 into the threaded hole of the syringe base 1, so that its tip slightly contacts the bottom surface of the syringe 2. Using an Allen wrench to rotate each set screw 31, the local position of the syringe 2 can be precisely raised or lowered, thereby achieving overall leveling adjustment. After the leveling is correct, screw the first fixing bolt 32 into the syringe base 1 and into the threaded hole at the bottom of the syringe 2 to firmly secure the syringe 2. In this embodiment, three syringe height adjustment mechanisms 3 are evenly distributed, each mechanism containing two set screws 31 and one first fixing bolt 32 to achieve optimal leveling effect.

[0023] like Figure 8 As shown, the positioning block 41 of the syringe positioning mechanism 4 is fastened to the syringe base 1 by two second fixing bolts 42. Loosening the second fixing bolts 42 allows for coarse adjustment by moving the positioning block 41 as a whole. For fine adjustment, rotating the positioning bolt 43 so that its end abuts against the inner wall of the syringe 2 allows for fine adjustment of the radial position of the syringe 2, correcting its concentricity with the syringe base 1. After adjustment, tightening the second fixing bolts 42 secures the positioning block 41. Similarly, the syringe positioning mechanism 4 also has multiple mechanisms, such as three, evenly distributed, each mechanism containing two second fixing bolts 42 and one positioning bolt 43.

[0024] like Figure 3 and Figure 4As shown, the bottom of the syringe 2 has an annular groove 21, and the syringe base 1 has a corresponding annular protrusion 11. The protrusion 11 is embedded in the groove 21, forming the first line of defense. Crucially, the width of the groove 21 is greater than the width of the protrusion 11; this gap allows for adjustment. On the inner side of the protrusion 11, closer to the center of the syringe base, the syringe base 1 has an annular oil guide groove 5 machined around its edge. Any lubricating oil seeping from the mating surfaces of the syringe 2 and syringe base 1 will first be blocked by the protrusion 11 and then guided into the oil guide groove 5 due to capillary action and gravity. Figure 7 As shown, the bottom of the oil guide trough 5 is preferably provided with holes to connect a detachable oil storage tank 6 or an oil storage tank with a discharge port to achieve centralized collection of leaked oil.

[0025] Working principle: First, align the groove 21 of syringe 2 with the protrusion 11 of syringe base 1. Second, use the set screws 31 of the syringe height adjustment mechanism 3 at each point to initially level the syringe 2. Then, use the positioning bolts 43 of the syringe positioning mechanism 4 to fine-tune the concentricity of the syringe 2. During the adjustment process, it can be repeatedly checked until the levelness and concentricity meet the requirements. Finally, tighten all the first fixing bolts 32 and the second fixing bolts 42 in sequence to complete the installation. During equipment operation, leaked lubricating oil will be effectively collected by the oil guide groove 5 and the oil storage groove 6 system.

[0026] In one embodiment, both the set screw 31 and the first fixing bolt 32 have hexagonal sockets on their heads. This design allows for operation with a standard hexagonal wrench, providing a large contact area, even force application, and reduced slippage, making it particularly suitable for space-constrained installation environments. This greatly facilitates disassembly and assembly of the mechanism, improves maintenance efficiency, and avoids the risk of stripping threads that may occur when using a screwdriver.

[0027] In one embodiment, the syringe height adjustment mechanism 3 is provided in multiple parts and evenly distributed on the syringe base 1. This technical solution can achieve more precise and stable correction of the syringe's levelness through multi-point uniform adjustment. The stress generated at a single adjustment point is small, avoiding the problem of syringe deformation or inaccurate adjustment caused by excessive force at a single point, ensuring the overall flatness of the syringe mounting surface, and thus guaranteeing the stability of the syringe operation.

[0028] In one embodiment, each syringe height adjustment mechanism 3 is provided with two set screws 31 and one first fixing bolt 32. This technical solution adopts a "two-top-one-bolt" configuration, where the two set screws are responsible for precise local height adjustment, and the first fixing bolt is responsible for final tightening. This clearly defined structure ensures that the leveling operation and the tightening operation do not interfere with each other. Fine adjustment is performed before tightening, ensuring that the adjustment accuracy is not lost during the tightening process, making the structure more scientific and reasonable.

[0029] In one embodiment, the bottom of the oil guide groove 5 is connected to an oil storage tank 6. This design uses the oil guide groove to intercept and collect leaked lubricating oil, while the oil storage tank provides a dedicated space to temporarily store a certain amount of waste oil. This complete "guide-collection" system prevents lubricating oil from flowing disorderly across the syringe holder surface or overflowing from the oil guide groove, achieving controllable management of leaked lubricating oil. Only periodic cleaning of the oil storage tank is required, greatly improving the cleanliness and ease of maintenance of the equipment.

[0030] In one embodiment, the syringe positioning mechanism 4 is provided in multiple units and evenly distributed on the syringe base 1. This technical solution allows multiple positioning mechanisms to apply forces to the inner wall of the syringe from different directions, which can effectively correct the radial runout of the syringe and ensure its concentricity with the syringe base. The even distribution balances the corrective forces, preventing the syringe from tilting during adjustment and improving the accuracy and reliability of the adjustment.

[0031] In one embodiment, each syringe positioning mechanism 4 is provided with two second fixing bolts 42 and one positioning bolt 43. This technical solution adopts a "two-adjustment-one-fixation" configuration. The two second fixing bolts can firmly press the positioning block onto the syringe seat, ensuring the stability of the positioning block as an adjustment base. The positioning bolt is dedicated to radial fine adjustment. This structure ensures that the positioning block itself will not shift during concentricity adjustment, making the adjustment action more precise and effective.

[0032] In one embodiment, the first fixing bolt 32 is provided with an anti-slip pad, which is located between the fixing bolt 32 and the syringe seat 1.
