[0002] The performance of the bottom plate in the computer flat knitting machine will directly affect the weaving function of the computer flat knitting machine. The design of the existing same-speed tuck structure of the bottom plate of the computer flat knitting machine is not reasonable. At present, the movement of the same-speed tuck triangle is mainly completed by electromagnets and connecting rods. The transmission structure through electromagnets and connecting rods is unstable, the mechanism is subjected to impact loads and the noise is loud, which reduces the performance of the bottom plate of the computer flat knitting machine and affects the weaving function of the computer flat knitting machine.

[0003] Prior art publication number CN215517855U discloses a straight needle selection computer flat knitting machine bottom plate with a same-speed lifting eye structure, including a same-speed lifting eye triangle, the same-speed lifting eye triangle is movably embedded in the middle and upper parts of the left needle connecting eye triangle and the right needle connecting eye triangle on the bottom plate body, when the same-speed lifting eye triangle protrudes from the bottom plate body, the lifting eye triangle contacts the heel of the needle selection plate; when the same-speed lifting eye triangle is retracted into the bottom plate body, the left needle connecting eye triangle and the right needle connecting eye triangle contact the heel of the needle selection plate. The utility model uses a stepping motor to control the needle transfer cam and the same-speed lifting eye cam in the structure, so that the mechanism switches between the needle transfer action and the lifting eye action, making the operation more stable and efficient, and a stepping motor is more cost-saving, greatly increasing the work efficiency.

[0061] A sealing ring 718 is fixedly arranged above the inner wall of the sliding cavity 716, and the sealing ring 718 can prevent the lubricating oil inside the bottom plate body 1 of the flat knitting machine from leaking out. A second spring installation cavity 719 is opened below the sliding cavity 716, and a second spring 720 is wound around the outer surface of the sliding rod 717, and the lower end of the second spring 720 is fixedly connected to the bottom of the second spring installation cavity 719, and the outer surface of the sliding rod 717 is fixedly connected to the upper end of the second spring 720.

[0062] The working principle of the same-line tuck structure of the bottom plate of a straight-selection needle computerized flat knitting machine based on Example 1 is as follows:

[0063] First, when using this base plate, the flat knitting machine connecting column 8 in this base plate is connected to the computer flat knitting machine, and the circuit of the computer flat knitting machine is connected to the circuit of this base plate so that this base plate can be controlled and operated by the computer flat knitting machine.

[0064] Second, when the base plate needs to perform the lifting operation, the computer flat knitting machine is used to control the motor 71 in the base plate to work. The motor 71 drives the screw 72 to rotate. The rotation of the screw 72 drives the sliding block 713 to move in the sliding groove 73. When the sliding block 713 moves, it drives the ejection block 714 to move. The movement of the ejection block 714 applies an upward squeezing force to the lower end of the sliding rod 717, thereby pushing the sliding rod 717 to move upward. When the sliding rod 717 moves upward, the second spring 720 is deformed by the pulling force of the sliding rod 717 to store energy, and then automatically resets after the sliding rod 717 loses the squeezing force of the ejection block 714.

[0065] Third, because there are two groups of ejection blocks 714, the ejection blocks 714 can eject the connecting and transition triangles 721 and the right tuck triangle 722 at one time to perform the right tuck work of the base plate, or eject the connecting and transition triangles 721 and the left tuck triangle 723 to perform the left tuck work of the base plate. The advantage of doing so is that the left and right tuck work of the base plate can be switched more quickly.

[0066] Fourth, when the sliding block 713 slides, the sliding block 713 can push the lubricating oil in the sliding groove 73, the top block sliding groove 74 and the oil flow cavity 75 to flow. When the oil in the oil flow cavity 75 flows, it passes through the filter cavity 76. After the oil enters the filter cavity 76, it is filtered by the filter element 79, thereby extending the use time of the lubricating oil in the base plate and reducing the maintenance times of the base plate.

[0067] Fifth, at the same time, when the filter element 79 needs to be replaced, the gate plate 712 is pulled to the left. When the gate plate 712 moves to the left, the first spring 711 is deformed by the leftward thrust of the gate plate 712 to store energy. After the leftward thrust of the gate plate 712 is released, the gate plate 712 can be automatically reset to close automatically, and then the filter element 79 can be taken out. When replacing the filter element 79, the positioning slide groove 77 and the positioning block 78 can be used to quickly install the new filter element 79 into the filter chamber 76, making it more convenient to replace the filter element 79 in the bottom plate.

[0068] The utility model provides a straight-select needle computerized flat knitting machine bottom plate peer tuck structure through improvement, and is provided with a sliding block 713, and is used to push out the connecting tuck transition triangle 721 and the right tuck triangle 722 to carry out the right side tuck work of the bottom plate, or to push out the connecting tuck transition triangle 721 and the left tuck triangle 723 to carry out the left side tuck work of the bottom plate, and the advantage of this is that the left and right side tuck work of the bottom plate can be switched more quickly; at the same time, a filter element 79 is provided, and is used to push the sliding groove 73, the top block sliding groove 74 and the lubricating oil in the oil flow cavity 75 to flow into the filter cavity 76, and then be filtered by the filter element 79, thereby extending the use time of the lubricating oil in the bottom plate, thereby reducing the maintenance times of the bottom plate.

[0069] The above shows and describes the basic principle, main features and advantages of the utility model, and the standard parts used in the utility model can be purchased from the market, and special-shaped parts can be customized according to the description and the drawings. The specific connection methods of each part adopt mature conventional means such as bolts, rivets, welding, etc. in the prior art. Machinery, parts and equipment all adopt conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art, which will not be described in detail here.

[0070] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
