Description

Technical Field

[0001] The present invention belongs to the technical field of computer flat knitting machines, and particularly relates to a single-groove double-needle needle plate. Background Art

[0002] A computer flat knitting machine is a double-needle bed latch needle weft knitting machine. Its cam device is like a set of planar cams. The needle feet of the knitting needles can enter the grooves of the cams. By moving the cam device, the knitting needles can make regular lifting movements in the needle grooves of the needle plate, and cooperate with the actions of the needle hooks and needle tongues to knit the yarn into a knitted fabric. The specific principle is as follows: During the upward movement of the knitting needle, the loop gradually exits the needle hook, the needle tongue is opened, and the needle tongue exits and hangs on the needle bar; during the downward movement of the knitting needle, the needle hook hooks the newly laid yarn and pulls it into a loop, while the original loop then exits the needle hook, and the new loop passes through the old loop and is connected in series with the old loop. The loop strings formed by numerous knitting needles are interconnected to form a knitted fabric.

[0003] Currently, during the operation of a computer flat knitting machine, a needle plate is required to install and fix multiple knitting needles. The single-groove double-needle needle plate can install the long needles and short needles simultaneously through one groove, without the need to install the long needles and short needles through two needle plates, reducing the weight of the machine head and increasing the working efficiency of the computer flat knitting machine.

[0004] However, during the use of the existing single-groove double-needle needle plate, although it has the functions of a double-layer needle plate, since the two knitting needles are located in one groove, they are prone to collision, resulting in damage to the knitting needles during long-term use.

[0005] Therefore, we propose a single-groove double-needle needle plate to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to propose a single-groove double-needle needle plate, which separates the first knitting needle and the second knitting needle placed in the same needle groove by setting a protective steel sheet to prevent the first knitting needle and the second knitting needle from colliding and wearing, improving the protection effect on the first knitting needle and the second knitting needle, and facilitating the extension of the service life of the knitting needles.

[0007] To achieve the above purpose, the present invention adopts the following technical solutions:

[0014] As a further preferred solution, the protective steel sheet includes a steel sheet body, and copper layers for directly contacting the first knitting needle or the second knitting needle are symmetrically electroplated on both sides of the steel sheet body.

[0015] Through the above technical solution, the setting of the copper layer can improve the protection effect on the first knitting needle and the second knitting needle, avoid friction damage between the first knitting needle and the second knitting needle and the protective steel sheet, and further improve the service life of the knitting needle.

[0016] As a further preferred solution, a fixing seat is detachably fixed to the bottom of the needle plate body, and the fixing seat is used for installation on a flat knitting machine device.

[0018] As a further preferred solution, an installation groove is opened in the middle of the upper end surface of the fixing seat, two vertical positioning columns are symmetrically fixed in the installation groove, the top ends of the positioning columns penetrate out of the upper end surface of the fixing seat, and a positioning groove is opened on the lower end surface of the needle plate body, and the top ends of the two positioning columns are inserted into both ends of the positioning groove.

[0019] Through the above technical solution, the needle plate body and the fixing seat can be quickly positioned by the cooperation of the positioning columns and the positioning groove.

[0020] As a further preferred solution, a driving lead screw is rotatably installed in the installation groove. Two opposite threads are symmetrically formed on the driving lead screw. Tightening columns are respectively sleeved on the two threads of the driving lead screw. The tops of the two tightening columns vertically extend into the positioning groove, and locking columns horizontally inserted into the inner wall of the positioning groove are formed on the side surfaces of the tops of the tightening columns.

[0021] Through the above technical solution, the tightening column can be driven to move by rotating the driving lead screw, and the locking column on the tightening column is horizontally inserted into the inner wall of the positioning groove to form a fixation.

[0022] As a further preferred solution, horizontally arranged fixing grooves are symmetrically formed on the inner walls at both ends of the positioning groove. The locking column horizontally penetrates the top end of the positioning column and is inserted into the fixing groove.

[0023] Through the above technical solution, the positioning groove is inserted and fixed with the locking column through the fixing groove.

[0024] As a further preferred solution, both ends of the driving lead screw respectively penetrate through the front and rear ends of the fixed seat, and knurled nuts are respectively formed on both ends.

[0025] Through the above technical solution, the driving lead screw can be rotated through the knurled nut.

[0026] As a further preferred solution, accommodating grooves are symmetrically formed at the positions where the driving lead screw penetrates through the front and rear ends of the fixed seat, and the knurled nuts are placed in the accommodating grooves.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0039] Refer to Figure 1, A single-slot double-needle needle plate, comprising a needle plate main body 1. At the upper end of the needle plate main body 1, there are multiple inserting slots 2, which are arranged along the length direction of the needle plate main body 1 between the two ends of the upper end face of the needle plate main body 1. A first inserting piece 3 and a second inserting piece 4 are symmetrically installed in the inserting slot 2. And the multiple inserting slots 2 are arranged along the width direction of the upper end face of the needle plate main body 1, and the adjacent inserting slots 2 are arranged equidistantly and parallelly, so that the first inserting piece 3 and the second inserting piece 4 can be regularly installed on the upper end face of the needle plate main body 1 to form multiple equidistant and parallel needle slots.

[0040] At the same time, in cooperation with Figure 2 , in the needle slot formed between the adjacent first inserting piece 3 and the second inserting piece 4, a first knitting needle 301 and a second knitting needle 401 are correspondingly installed, and a protective steel sheet 5 is arranged between the first knitting needle 301 and the second knitting needle 401, so that the protective steel sheet 5 can be used to separate the first knitting needle 301 and the second knitting needle 401 placed in the same needle slot to prevent the first knitting needle 301 and the second knitting needle 401 from colliding and wearing, which can improve the protection effect on the first knitting needle 301 and the second knitting needle 401 and is beneficial to extending the service life of the knitting needle. And in specific implementation, as Figure 3 shown, the protective steel sheet 5 includes a steel sheet main body 501, and copper layers 502 for directly contacting the first knitting needle 301 or the second knitting needle 401 are symmetrically electroplated on both sides of the steel sheet main body 501. Therefore, through the setting of the copper layers 502, the protection effect on the first knitting needle 301 and the second knitting needle 401 can be improved to avoid friction damage between the first knitting needle 301 and the second knitting needle 401 and the protective steel sheet 5, and further improve the service life of the knitting needle.

[0041] Referring to Figure 1 , Figure 4 and Figure 5 , a fixing seat 6 is detachably fixed to the bottom of the needle plate main body 1, and the fixing seat 6 is used for installing on the corresponding components of the flat knitting machine equipment. Thus, the needle plate main body 1 can be detachably installed by using the fixing seat 6, so that the needle plate main body 1 can be conveniently disassembled and assembled from the flat knitting machine equipment to facilitate the disassembly, assembly and maintenance of the needle plate main body 1 in the later stage.

[0042] In specific implementation, in cooperation with Figure 6 , a mounting groove 7 is opened in the middle of the upper end face of the fixing seat 6, and two vertical positioning columns 701 are symmetrically fixed in the mounting groove 7. The top ends of the positioning columns 701 penetrate out of the upper end face of the fixing seat 6, and a positioning groove 9 is opened on the lower end face of the needle plate main body 1. The top ends of the two positioning columns 701 are inserted into both ends of the positioning groove 9, so that the needle plate main body 1 and the fixing seat 6 can be quickly positioned by the cooperation of the positioning columns 701 and the positioning groove 9.

[0043] Meanwhile, a driving lead screw 8 is rotatably installed in the installation groove 7. Two opposite threads are symmetrically formed on the driving lead screw 8. Tightening columns 10 are respectively sleeved on the two threads of the driving lead screw 8. The tops of the two tightening columns 10 vertically extend into the positioning groove 9. A locking column 11 horizontally inserted into the inner wall of the positioning groove 9 is formed on the side surface of the top of the tightening column 10. Horizontally arranged fixing grooves 901 are symmetrically opened on the inner walls at both ends of the positioning groove 9. Specifically, the locking column 11 horizontally penetrates the top end of the positioning column 701 and is inserted into the fixing groove 901, so that the positioning groove 9 can form plug-in fixation with the locking column 11 through the fixing groove 901.

[0044] Therefore, the user can drive the tightening column 10 to move by rotating the driving lead screw 8, and the locking column 11 on the tightening column 10 is horizontally inserted into the inner wall of the positioning groove 9 to form fixation. During specific implementation, both ends of the driving lead screw 8 respectively pass through the front and rear ends of the fixing seat 6, and screw caps 801 are respectively formed thereon, so that the user can rotate the driving lead screw 8 through the screw caps 801. Accommodation grooves 601 are symmetrically opened at the positions where the driving lead screw 8 passes through the front and rear ends of the fixing seat 6. The screw caps 801 are placed in the accommodation grooves 601, so that the accommodation grooves 601 can be used to accommodate the screw caps 801 to prevent the screw caps 801 from protruding and affecting the overall installation and use of the device.

[0045] Working principle: When in use, the single-groove double-needle needle plate can fix the fixing seat 6 on the corresponding component of the flat knitting machine by using existing technical means. Then, the needle plate body 1 can be quickly positioned on the fixing seat 6 by docking the positioning column 701 with the positioning groove 9 on the lower end surface of the needle plate body 1. At this time, the driving lead screw 8 can be rotated by screwing the screw cap 801, so that the two tightening columns 10 on the driving lead screw 8 move away from each other. Thus, the locking column 11 at the top of the tightening column 10 penetrates the top of the positioning column 701 and is horizontally inserted and fixed with the fixing groove 901 in the positioning groove 9 to install the needle plate body 1 on the fixing seat 6. Therefore, during maintenance, the needle plate body 1 can be quickly disassembled and assembled from the fixing seat 6, which is beneficial for the staff to carry out maintenance work and is convenient to use.

[0046] Meanwhile, when the needle plate body 1 is used after being installed on the fixed seat 6, the first knitting needle 301 and the second knitting needle 401 can be installed in the needle slots formed between the first insert piece 3 and the second insert piece 4 in the insert piece slot 2, and the protective steel sheet 5 is used to separate the first knitting needle 301 and the second knitting needle 401 in the same needle slot, so as to prevent the first knitting needle 301 and the second knitting needle 401 from colliding and wearing, and to achieve the protection effect during the process of realizing the protection function. Meanwhile, during the process of preventing the knitting needles from wearing, the protective steel sheet 5 is in contact with the first knitting needle 301 and the second knitting needle 401 through symmetric copper layers 502 provided on both sides of the steel sheet body 501 by electroplating. Therefore, the low-strength property of the copper layer 502 can be utilized to further improve the protection effect on the first knitting needle 301 and the second knitting needle 401, which is beneficial to extending the service life of the knitting needles.

[0047] As mentioned above, the above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
