Definitions

  • the present invention relates to a needle bed transmission mechanism for a warp knitting machine with a single needle bed, and specifically discloses a needle bed crankshaft-connecting rod mechanism for a warp knitting machine with a single needle bed.
  • Warp knitting machine is a knitting machine that uses chemical fibers as the raw material to knit apparel fabrics, underwear fabrics, swimsuit fabrics, curtain fabrics, household fabrics and industrial fabrics. As the warp knitting machine only uses warps to knit fabrics, it has been very popular in the textile industry thanks to the advantages such as short industrial process for production, high production efficiency, a great number of fabric varieties, low investments and low energy consumption.
  • the cam-type transmission mechanism has been extensively used as the needle bed transmission mechanism for existing warp knitting machines. Since the cam has relatively high inertia and centrifugal force during rotation, the operating speed of the machine is affected, and the production efficiency of the machine cannot be further improved.
  • the object of the present invention is to overcome the problems above by providing a needle bed crankshaft-connecting rod mechanism for a warp knitting machine with a single needle bed, which can effectively shorten the stroke of the needle bed connecting rod mechanism, such that its vibration and inertia are low, and the machine can be operated at a higher speed, thereby improving the production efficiency.
  • a plurality of grooves is formed on the connecting rod frame, and the crankshaft is fixed in the grooves and can rotate freely.
  • one end of the connecting rod a is connected with the crankshaft, and the other end thereof is connected with a pin shaft a and can rotate around the pin shaft a.
  • a clamping device is disposed at the connection between the connecting rod a and the crankshaft, and the contact surface of the clamping device with the crankshaft is a circular-arc concave surface with a bearing shell installed thereon.
  • the pin shaft a is further connected with the connecting rod b
  • the connecting rod b is divided into two parts, left and right, which are arranged symmetrically and in parallel on two sides of the pin shaft a and can rotate around the pin shaft a.
  • the other end of the connecting rod b is connected with the pin shaft b and can rotate around the pin shaft b.
  • two ends of the pin shaft a and the pin shaft b are provided with a connecting rod c and a connecting rod d, respectively, and they can all rotate around the pin shafts.
  • the connecting rod c and the connecting rod d are both provided with a plurality of protruding columns a and columns b, the columns are sheathed by steel jackets, and the steel jackets are installed into the grooves of the connecting rod frame.
  • a connecting rod e is disposed at the central position of the pin shaft b, the connecting rod e can rotate around the pin shaft b, the connecting rod e is provided with a fastening device thereon for adjusting the tightness between the connecting rod e and the pin shaft b, and the other end of the connecting rod e is connected with the looping part.
  • connecting rod frame 2. crankshaft, 3. connecting rod a, 4. connecting rod c, 5. column a, 6. pin shaft a, 7. connecting rod b, 8. connecting rod d, 9. column b, 10. pin shaft b, 11. connecting rod e.
  • a needle bed crankshaft-connecting rod mechanism for a warp knitting machine with a single needle bed is mainly composed of a connecting rod frame 1, a crankshaft 2, a plurality of connecting rods 3, 4, 7, 8, 11 and pin shafts 6, 10.
  • a plurality of grooves is formed on the connecting rod frame 1, and the crankshaft 2 is fixed in the grooves and can rotate freely.
  • One end of the connecting rod a3 is connected with the crankshaft 2, and the other end thereof runs into a pin shaft a6 and can rotate around the pin shaft a6.
  • a clamping device is disposed at the connection between the connecting rod a3 and the crankshaft 2, and the contact surface of the clamping device with the crankshaft 2 is a circular-arc concave surface, the clamping device is divided into two parts with a bearing shell installed in each of the parts, the bearing shell is formed with a small hole thereon, the separated two parts sheathe the crankshaft 2 and are fastened by tightening screws through the threaded holes on two sides of the two parts, a lubrication system injects oil into the small holes, such that a thin oil film is formed between the bearing shell and the crankshaft 2.
  • the advantage of such a practice is that the rotation of the crankshaft 2 becomes smoother, and the friction between the crankshaft 2 and the bearing shell is reduced. As a result, the crankshaft 2 is very well protected, the operating load on the power device and the force applied mutually on the transmission parts are reduced, and the machine operates more steadily and smoothly while electric power is saved.
  • the pin shaft a6 is further connected with the connecting rod b7, the connecting rod b7 is divided into two parts, left and right, which are arranged symmetrically and in parallel on two sides of the pin shaft a6 and can rotate around the pin shaft a6.
  • the other end of the connecting rod b7 is connected with the pin shaft b10 and can rotate around the pin shaft b10.
  • the pin shaft a6 and the pin shaft b10 are parallel to each other, two ends thereof are provided with a connecting rod c4 and a connecting rod d8, respectively, and they can all rotate around the pin shafts.
  • the connecting rod c4 and the connecting rod d8 are both provided with a plurality of protruding columns a5 and columns b9, the columns are sheathed by steel jackets, and the steel jackets are installed into the grooves of the connecting rod frame.
  • a connecting rod e11 is disposed at the central position of the pin shaft b10, the connecting rod e11 can rotate around the pin shaft b10, the connecting rod e11 is provided with a fastening device thereon for adjusting the tightness between the connecting rod e11 and the pin shaft b10, and the other end of the connecting rod e11 is connected with the looping part.
  • the transmission device drives the crankshaft 2 to rotate, and the crankshaft 2 drives, via the needle bed connection rod, the looping part to make looping motion.
