Description

Technical Field

[0001] This invention relates to the field of glove machines, and specifically to a triangular system for glove machines. Background Technology

[0002] The basic structure of a computerized glove machine is as follows: between the left and right bases, there are front and rear needle beds. The needle beds have movable knitting needles in their needle grooves. The front and rear heads are equipped with triangular base plates, which move horizontally left and right with the knitting heads. Since there are various triangles on the triangular base plates, the needle selection, starting, and clearing actions are performed through the interaction between the triangles and the needle heels of the knitting needles (combination needles), thus completing various knitting functions.

[0003] Existing computerized glove machines generally connect the front and rear heads through a head connection device, and drive them through a drive device to achieve synchronous movement of the front and rear heads.

[0004] However, in this type of glove machine, the front and rear knitting heads are in an "idling" state for half of each round trip, without knitting gloves. Therefore, in the patent "CN114182422A" published in March 2022 by applicant Shi Xiaochuan, a solution was proposed: eliminating the knitting head connecting device and controlling the front and rear knitting heads separately through a servo motor, so that the glove machine can knit during the round trip of both the front and rear knitting heads. The claimed core technology of this function is in the following aspects: [D1 Specification Paragraph 0045]

[0005] "1. The front and rear needle guide heads are driven independently by two servo motors (other ordinary glove machines are driven by one motor for the front and rear needle guide heads). Of course, they can also be driven by one motor and converted by a mechanical structure to realize the conversion between the staggered movement and parallel movement of the front and rear needle guide heads;

[0006] Second, each yarn feeder is also driven independently by a stepper motor or servo motor;

[0007] 3. The starting triangle of the front and rear needle guide heads should be able to push up the needles on the needle bed and adjust the descent of the needles when moving in both left and right directions.

[0008] However, after research, the applicant believes that using a front servo motor and a rear servo motor to achieve differential operation, and to realize differential or synchronous reciprocating motion of the front and rear needle heads, requires high control precision for the two servo motors (the switch between differential and synchronous operation needs to be made), is difficult to debug, and is inconvenient to maintain.

[0009] Therefore, on August 9, 2023, the applicant applied for a glove knitting process, CN117026490A, which employs a multi-system synchronous operation method to achieve the above-mentioned purpose. The involved triangular system (including a triangular base plate and various triangles) is as follows... Figure 1 As shown, in the middle of the first triangular base plate 000, there is an integrated upper Zhongshan triangle 001 (which actually functions as two upper Zhongshan triangles in a regular glove machine, with a lower Zhongshan triangle on each of its left and right sides). Below the upper Zhongshan triangle 001, there are two adjacent elastic band triangles 002 (used for elastic band weaving), and a starting triangle 003 is set on both sides of the elastic band triangle. On each side of the upper Zhongshan triangle, there is also a density triangle (formerly known as a mesh triangle) 004.

[0010] After a period of production trials, the applicant further improved the aforementioned structure, such as... Figure 2 As shown, the two starting triangles (011, 012) are arranged in an overlapping manner, and the two elastic triangles (013, 014) located in the middle are placed on the left and right sides to simplify the size of the entire triangle system, shorten the needle path, and make knitting more efficient: the needles on the other side of the triangle base plate can start knitting before the needles on one side of the triangle base plate have finished knitting, thereby improving knitting efficiency (this principle is described in detail in the applicant's prior patent 202311509297.X filed on 2023.11.14, and will not be elaborated here).

[0011] To accommodate the above scheme and ensure the original weaving function, the density triangles on both triangular base plates have been improved: the sides (015, 016) of the density triangles on both sides of the first triangular base plate have been made into a swing-type structure, so that during normal weaving, as... Figure 2 The density triangle 015 indicates the unfolded state; when elastic band weaving is required, as shown... Figure 2 As shown in density triangle 016, starting from elastic band triangle 014, the swinging part of density triangle 016 is moved to the closed state. This design ensures that the elastic band triangles that have moved from the middle to both sides have a place to be installed, while also reducing the needle path when knitting the elastic band (by borrowing part of the space of the density triangle, and in conjunction with presser triangle 018 and guard triangle 019).

[0012] Correspondingly, the density triangle 017 located in the middle of the other second triangular base plate is made into a left-right swinging structure to match the overlapping starting triangles. This is also to ensure that the original function of the density triangle remains unchanged under the premise of shortening the stroke (refer to the applicant's earlier application 202323063331.3).

[0013] However, in actual production and application, the applicant discovered that... Figure 2When the medium-density triangle (0015, 0016) is in the unfolded state, the needle heel may be embedded in the unfolded gap under the tension of the yarn, which can easily increase the needle's resistance and may damage the needle.

[0014] Therefore, the inventors conducted further research and developed a triangular system for glove machines, which led to this invention. Summary of the Invention

[0015] The purpose of this invention is to provide a triangular system for a glove machine that solves the technical problems mentioned in the background art while retaining the double-sided knitting function of the glove machine.

[0016] To achieve the above objectives, the technical solution of the present invention is as follows:

[0017] A glove machine triangular system includes a first triangular base plate, which includes a first upper central triangular horn disposed in the middle, and first density triangular horns disposed on both sides of the first upper central triangular horn, with corresponding elastic band triangular horns disposed on the sides of the first density triangular horns. The first density triangular horn includes a telescopic part located on the side of the main body, which can extend or retract relative to the main body. When the telescopic part is in the extended state, the density triangular horn works normally. When the telescopic part is in the retracted state, an elastic band knitting needle passage is formed between the elastic band triangular horn and the first density triangular horn.

[0018] In the applicant's prior patent, the swinging part of the first density triangle was used to achieve the above function, but there was a problem that the needle heel would rise when the needle was moving. However, after adopting the technical solution of this application, the bottom of the telescopic part is a continuous boundary, and there is no problem that the needle heel moves up when the needle is pressed. Furthermore, through the movement of the telescopic part itself, the channel can be made open when the elastic band is being knitted, so as to ensure that the functions that the applicant needs to obtain in a series of improvements can be realized.

[0019] Furthermore, the retraction of the telescopic part is achieved through the action of the knitting needle: the side of the telescopic part near the elastic band triangle is an inclined surface. When the elastic band is being knitted, the heel of the knitting needle enters along the inclined surface of the telescopic part and presses the telescopic part into the first triangular base plate.

[0020] This method can eliminate the need for an active control drive source for the telescopic part, and the needle pressure alone can be used to push out the needle path during the weaving of the elastic band.

[0021] Furthermore, the extension of the telescopic part is achieved by a return spring located on its back.

[0022] During normal knitting, the needle heel moves from one side of the body of the first density triangle. During this process, the telescopic part is always extended under the action of the return spring and will not retract due to the action of the needle heel.

[0023] Furthermore, the telescopic part located on the left side of the first triangular base plate has a slope that is lower on the left and higher on the right; the telescopic part located on the right side of the first triangular base plate has a slope that is lower on the right and higher on the left.

[0024] Furthermore, the starting position of the elastic band triangle located on the left side of the first triangular base plate is on the left, and the starting position of the elastic band triangle located on the right side of the first triangular base plate is on the right; the starting direction of the corresponding elastic band triangle on the second triangular base plate is opposite to the starting direction of the elastic band triangle on the first and third triangular base plates.

[0025] Because the needle-feeding process of the entire triangular base plate is more compact, in order to prevent the elastic triangles on the front and rear triangular base plates from interfering with each other, the starting direction of the elastic triangles on the two triangular base plates is set to be opposite, and the normal operation of the elastic triangles is achieved by the back-and-forth movement of the machine head.

[0026] Furthermore, it also includes a second triangular base plate, which includes a swing density triangle and an auxiliary density triangle. The swing density triangle is located between two second upper mountain triangles. When the lower end of the swing density triangle swings to the left, its end connects with the side end of the auxiliary density triangle on the left. When the lower end of the swing density triangle swings to the right, its end connects with the side end of the auxiliary density triangle on the right.

[0027] This setting is also to prevent the needle heel from entering the gap between the auxiliary density triangle and the oscillation density triangle.

[0028] Furthermore, the oscillating density triangle and the auxiliary density triangle are set in their respective grooves, and the oscillating density triangle and the auxiliary density triangle are linked together.

[0029] Furthermore, the first triangular base plate includes two starting triangles located below the first upper mountain triangle, with the two starting triangles partially overlapping each other so that their stitching hypotenuses intersect.

[0030] By adopting the above solution, the present invention has the following advantages compared with the prior art:

[0031] By optimizing the double-sided knitting of the glove machine, the structure of the density triangle and elastic triangle positions was further simplified, so that it can improve the knitting efficiency of the elastic band without affecting the control of the density triangle on the needle heel, thus ultimately optimizing the production efficiency of the glove machine.

[0047] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0048] As can be seen from the prior patent applications provided in the background art, the existing density triangles all move up and down relative to the base plate to control the glove knitting size (i.e., the lower the density triangle is pressed, the larger the knitted glove size). Therefore, those skilled in the art would not and have no incentive to set the density triangle as a separate front-to-back telescopic structure. This invention, however, first develops a triangle system based on the goal of achieving double-sided knitting of gloves, then optimizes this system, and solves the discovered technical problems during the optimization process, thus arriving at the technical concept of this invention. Specific embodiments are shown below:

[0049] like Figure 3 As shown, a triangular system for a glove machine includes a first triangular base plate 1 and a second triangular base plate 2, wherein:

[0050] The first triangular base plate 1 includes a first upper central mountain triangle 15. Below the first upper central mountain triangle 15 are two first lower central mountain triangles (151, 152). Between the first lower central mountain triangles (151, 152) are two partially overlapping first starting triangles (16, 17) with staggered needle paths. Simultaneously, first density triangles (11, 12) are located on both sides of the first upper central mountain triangle 15. The most basic knitting process of the glove machine is as follows: after the needle heel is selected, the needle starts from the starting triangle, rises along the needle path between the upper and lower central mountain triangles to hook the yarn, then descends, and finally the density triangle controls the pull-down amplitude of the loop. The staggered starting triangles allow for a more compact time and space for the raising and lowering of the needles on the front and rear needle beds in double-sided knitting, thereby improving knitting efficiency.

[0051] Unlike prior patents, the first density triangles (11, 12) include a main body (111, 112) and telescopic parts (101, 102). The telescopic parts (101, 102) are located on the sides of their respective main bodies (111, 112) and can extend or retract relative to the main body. The side of the telescopic parts (101, 102) closest to the elastic band triangle is sloped. When knitting the elastic band, the heel of the knitting needle enters along the slope of the telescopic parts (101, 102) and presses the telescopic parts (101, 102) into the base plate 1 of the first triangle. Figure 4 , Figure 5 As shown, the telescopic part 101 located on the left side of the first triangular base plate 1 has a slope 1011 that is lower on the left and higher on the right, so that when the knitting needle enters from the left, the telescopic part can be pressed into the triangular base plate; the telescopic part 102 located on the right side of the first triangular base plate 1 has a slope that is lower on the right and higher on the left, so that when the knitting needle enters from the right, the telescopic part can be pressed into the triangular base plate.

[0052] The repositioning of the telescopic parts (101, 102) is achieved by a return spring located on their back. During normal knitting, after descending from the needle path of the first upper cam 15, the needle heel descends along the side of the first density cam (11, 12), while the needle heel travels from one side of the body of the first density cam (11, 12). During this process, the telescopic parts (101, 102) remain extended under the action of the return spring and are not retracted by the needle heel. Figure 5 For example, during the process from the low point 113 of the main body to the low point 103 of the telescopic part, the needle heel of the knitting needle is continuously subjected to the action of the telescopic part and will not move upward, that is, the density triangle is in normal working condition.

[0053] Meanwhile, the starting position of the first elastic triangle 13 located on the left side of the first triangular base plate 1 is on the left, and the starting position of the first elastic triangle 14 located on the right side of the first triangular base plate 1 is on the right; the starting direction of the corresponding elastic triangle on the second triangular base plate 2 is opposite to the starting direction of the elastic triangle on the first and third triangular base plates. By setting the starting direction of the elastic triangles on the two triangular base plates to be opposite, the normal operation of the elastic triangle is achieved by the back-and-forth movement of the machine head.

[0054] The pressure pin triangle 18 and the protective pin triangle 19 on the first triangular base plate have the same structure and function as those in the prior patent, and will not be elaborated here.

[0055] The second triangular base plate 2 includes a swing density triangle 21 and auxiliary density triangles (201, 202). The swing density triangle 21 is located between two second upper mountain triangles. The swing density triangle 21 and the auxiliary density triangles (201, 202) are set in their respective grooves, and the swing density triangle 21 and the auxiliary density triangles (201, 202) are linked. When the lower end of the swing density triangle 21 swings to the left, its end connects with the side end of the auxiliary density triangle 201 on the left. When the lower end of the swing density triangle 21 swings to the right, its end connects with the side end of the auxiliary density triangle 202 on the right. This arrangement is also to prevent the heel of the knitting needle from entering the gap between the auxiliary density triangles (201, 202) and the swing density triangle 21.

[0056] The above are merely specific embodiments of the present invention. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in the present invention are for reference only and are not absolute limitations. Any non-substantial modifications made using the present invention shall be considered as infringing upon the protection scope of the present invention.
