Description

Technical Field

[0001] The utility model relates to the field of glove knitting machines, in particular to a glove knitting machine with elastic bands and a density triangle structure. Background Art

[0002] The basic structure of the computer glove machine is: between the left and right bases, there are front and rear needle beds, movable knitting needles are arranged in the needle grooves of the needle beds, and cam bottom plates are arranged on the split front and rear heads, and the cam bottom plates move left and right with the heads; because various cams are arranged on the cam bottom plates, the needles are selected, started and cleared through the interaction of the needle butts of the cams and the knitting needles (combination needles), so as to complete various knitting functions.

[0003] The existing computerized glove knitting machine generally connects the front and rear heads through a head connecting device, and is driven by a driving device to achieve synchronous movement of the front and rear heads.

[0004] However, when this type of glove machine is in operation, the front and rear heads are in an "idling" state for half of the process of one round trip, and gloves are not knitted. Therefore, in March 2022, the applicant Shi Xiaochuan published the patent "CN114182422A", which proposed a solution, that is, to cancel the head connection device, and the front and rear heads are respectively controlled by a servo motor, so that the glove machine can knit during the back and forth operation of the front and rear heads. The core functional technologies claimed are in the following aspects: [D1 specification paragraph 0045]

[0005] “First, the front and rear needle guide heads are driven independently by two servo motors (other ordinary glove machines have the front and rear needle guide heads driven by one motor). Of course, it can also be driven by one motor and converted by the mechanical structure to achieve the conversion between the offset motion and parallel motion of the front and rear needle guide heads;

[0006] Second, each yarn mouth is also independently driven by an independent stepper motor or servo motor;

[0007] 3. The needle lifting triangle of the front and rear needle guide heads can push the needles on the needle bed when moving in both directions, and adjust the range of the needle descent.

[0008] However, after research, the applicant believes that using the front servo motor and the rear servo motor to achieve differential operation and realize differential operation or synchronous reciprocating motion of the front guide needle head and the rear guide needle head requires high control accuracy of the two servo motors (switching between differential and synchronous is required), 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 adopts a multi-system synchronous operation method to achieve the above purpose, wherein the triangle system involved (the triangle system includes a triangle base plate and various triangles) is as follows Figure 1 As shown, in the middle of the first triangle bottom plate 000, an integrated upper Zhongshan triangle 001 is arranged (actually plays the role of two upper Zhongshan triangles of an ordinary glove machine, and a lower Zhongshan triangle is arranged on each side), two closely adjacent elastic triangles 002 (used for elastic weaving) are arranged below the upper Zhongshan triangle 001, and a needle raising triangle 003 is arranged on both sides of the elastic triangle, and a density triangle (formerly also called a mesh triangle) 004 is arranged on each side of the upper Zhongshan triangle.

[0010] After a period of production tests, the applicant has made improvements to the above structure, such as Figure 2 As shown, the two needle-casting triangles (011, 012) are arranged in an overlapping manner, and the two elastic triangles (013, 014) located in the middle are arranged on the left and right sides to simplify the size of the entire triangle system, shorten the needle movement trajectory of the knitting needles, and make knitting more efficient: when the knitting needles on the triangle bottom plate on one side have not yet completed knitting, the knitting needles on the triangle bottom plate on the other side have already started to cast on the needles, thereby improving the knitting efficiency (this principle is described in detail in the applicant's prior patent 202311509297.X with an application date of 2023.11.14, and will not be expanded).

[0011] In order to adapt to the above scheme and ensure the original weaving function, the density triangles on the two triangular bottom plates are improved: the density triangle sides (015, 016) on both sides of the first triangular bottom plate are made into a swinging structure. Figure 2 Density triangle 015 is in the unfolded state; when elastic band weaving is required, Figure 2 As shown in density triangle 016, start stitching from elastic triangle 014, and move the swing part of density triangle 016 to the closed state. This design not only ensures that the elastic triangles moved from the middle to the two sides have installation positions, but also reduces the needle track when knitting elastic (borrowing part of the space of the density triangle, and cooperating with the needle pressing triangle 018 and the needle guard triangle 019).

[0012] Correspondingly, the density triangle 017 located in the middle on the other second triangular bottom plate is made into a left-right swinging structure in order to cooperate with the staggered and overlapping needle-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 prior application 202323063331.3).

[0013] However, in the actual production application process, the applicant found that Figure 2When the medium-density triangles (0015, 0016) are in an expanded state, the butts of the knitting needles may be embedded in the expanded gaps under the tension of the yarn, which may easily increase the needle resistance of the knitting needles and may cause damage to the stitches.

[0014] Therefore, the inventor conducted further research and developed a glove machine elastic band and density triangle structure, which resulted in the present invention. Utility Model Content

[0015] The utility model aims to provide a glove knitting machine elastic band and density triangle structure, which can improve the glove elastic band knitting efficiency while maintaining the double-sided knitting function of the glove knitting machine, and will not affect the control of the density triangle on the needle butt of the knitting needle.

[0016] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0017] A glove machine elastic band, density triangle structure, including

[0018] A first triangular bottom plate, a first upper Zhongshan triangle is arranged in the middle of the first triangular bottom plate, first density triangles are arranged on both sides of the first upper Zhongshan triangle, corresponding first rubber triangles are arranged on the sides of the first density triangle, and the needle bevel of the first rubber triangle is located on the side close to the first density triangle;

[0019] A second triangular bottom plate, a second upper middle triangle is arranged on each side of the second triangular bottom plate, a second rubber triangle is arranged on the outer side below the second upper middle triangle, and the bevel direction of the second rubber triangle is opposite to the bevel direction of the first rubber triangle at the corresponding position.

[0020] In the concept of the utility model, in addition to avoiding the following Figure 2 In the 202323063331.3 shown, the needle heel will go up in the density triangle. Figure 2 The design shown also has the following features:

[0021] In this case, after the needle butt passes through the first density triangle, it directly passes through the first elastic triangle to pick up the elastic thread. The overall length of the elastic thread is controlled by the first needle pressing triangle. When the machine head runs in the opposite direction, although the elastic high-foot needle will pass through the first density triangle for a second pressing, the overall length of the elastic will not change. Figure 2 In the scheme shown in , after the first elastic triangle starts to eat the elastic thread, the overall length of the elastic thread is determined by the control depth of the first density triangle. During the knitting process, the control depth of the first density triangle is often deeper, which causes the elastic thread to become longer during the process of eating the thread, making it impossible to knit a smaller glove cuff.

[0022] Furthermore, a first needle pressing triangle is arranged on the first elastic triangle on one side of the first triangle bottom plate, and a needle guarding triangle is arranged on the first elastic triangle on the other side. The first needle pressing triangle or the needle guarding triangle and the respective first elastic triangle and the first density triangle form an elastic weaving channel.

[0023] The elastic band weaving channels on both sides of the first triangle bottom plate can enter the elastic band weaving channels after the density control of the first density triangle is completed. The trajectory of the elastic band weaving channel itself is consistent with the existing one, so the corresponding parts of the needle protection triangle or the needle pressing triangle need to be modified.

[0024] Furthermore, the first triangle bottom plate includes two needle raising triangles arranged below the first Zhongshan triangle, and the two needle raising triangles are partially overlapped so that the needle oblique edges thereof are staggered.

[0025] Furthermore, the elastic band braiding channel on one side of the second triangular bottom plate is formed by the second elastic band triangle and the second upper Zhongshan triangle, and the elastic band braiding channel on the other side is formed by the second elastic band triangle, the second upper Zhongshan triangle, and the second pressing needle triangle.

[0026] Furthermore, the second triangular bottom plate also includes a swinging density triangle and an auxiliary density triangle. The swinging density triangle is located between the two second upper Zhongshan triangles. When the lower end of the swinging density triangle swings to the left, its end is connected to the side end of the auxiliary density triangle on the left. When the lower end of the swinging density triangle swings to the right, its end is connected to the side end of the auxiliary density triangle on the right.

[0027] This arrangement is for preventing the butt of the knitting needle from entering the gap between the auxiliary density triangle and the swing density triangle.

[0028] Furthermore, the swing density triangle and the auxiliary density triangle are arranged in their respective slide grooves, and the swing density triangle and the auxiliary density triangle are linked.

[0029] After adopting the above scheme, the utility model has the following advantages compared with the prior art:

[0030] The double-sided knitting of the glove machine has been optimized, and the structure of the density triangle and the elastic triangle has been simplified, so that it can not only improve the efficiency of glove elastic knitting, but also will not affect the control of the density triangle on the needle butt, and finally realize the optimization of the production efficiency of the glove machine.

[0046] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0047] like Figure 5 As shown, a glove machine elastic band and density triangle structure comprises a first triangle bottom plate 1 and a second triangle bottom plate 2, wherein:

[0048] like Figure 3As shown, the first cam bottom plate 1 includes a first upper Zhongshan cam 15, two first lower Zhongshan cams (151, 152) are arranged below the first upper Zhongshan cam 15, and two first needle raising cams (16, 17) are arranged between the first lower Zhongshan cams (151, 152) and partially overlapped, and the needle bevels are staggered. At the same time, first density cams (11, 12) are arranged on both sides of the first upper Zhongshan cam 15. That is, the most basic knitting process of the glove machine is that after the needle butt of the knitting needle is selected, the needle is raised from the needle raising cam, and the yarn is raised along the needle passage between the upper and lower Zhongshan cams, and then lowered, and finally the pull-down amplitude of the coil is controlled by the density cam; and the staggered needle raising cams can make the time and space for the lifting and lowering of the front and rear needle beds more compact in double-sided knitting, so as to improve the knitting efficiency.

[0049] The needle starting position of the first rubber triangle 13 located on the left side of the first triangle bottom plate 1 is close to the low point of the first density triangle 11, and the needle starting position of the first rubber triangle 14 located on the right side of the first triangle bottom plate 1 is close to the low point of the first density triangle 12; a first needle pressing triangle 18 is arranged on the first rubber triangle 13, and a needle guarding triangle 19 is arranged on the first rubber triangle 14 on the other side. The first needle pressing triangle 18 or the needle guarding triangle 19 form an rubber weaving channel with their respective first rubber triangles and first density triangles; the rubber weaving channel can enter the rubber weaving channel after the density control of the first density triangle is completed, and the trajectory of the rubber weaving channel itself is consistent with the existing one, and is formed by modifying the corresponding parts of the needle guarding triangle or the needle pressing triangle.

[0050] like Figure 4 As shown, a second upper Zhongshan triangle (24, 25) is arranged on both sides of the second triangular bottom plate 2, and a second rubber triangle (22, 23) is arranged on the outer side below the second upper Zhongshan triangle. The rubber weaving channel on one side of the second triangular bottom plate is formed by the second rubber triangle 22 and the second upper Zhongshan triangle 24, and the rubber weaving channel on the other side is formed by the second rubber triangle 23, the second upper Zhongshan triangle 25, and the second needle pressing triangle 26. The needle raising direction of the second rubber triangle (22, 23) is opposite to the needle raising direction of the corresponding first rubber triangle on the first and third triangular bottom plates. The needle raising directions of the rubber triangles on the two triangular bottom plates are set to be opposite, and the normal operation of the rubber triangle is realized by the back and forth movement of the machine head.

[0051] The second triangle bottom plate 2 also includes a swinging density triangle 21 and an auxiliary density triangle (201, 202). The swinging density triangle 21 is located between the two second upper Zhongshan triangles. The swinging density triangle 21 and the auxiliary density triangle (201, 202) are arranged in their respective slide grooves, and the swinging density triangle 21 and the auxiliary density triangle (201, 202) are linked. When the lower end of the swinging density triangle 21 swings to the left, its end is connected to the side end of the auxiliary density triangle 201 on the left side. When the lower end of the swinging density triangle 21 swings to the right, its end is connected to the side end of the auxiliary density triangle 202 on the right side. This arrangement is to prevent the needle butt of the knitting needle from entering the gap between the auxiliary density triangle (201, 202) and the swinging density triangle 21.

[0052] The above are only specific embodiments of the present utility model. At the same time, all words such as "upper, lower, left, right, middle" involved in the present utility model are for reference only and are not absolutely limiting. Any non-substantial changes made using the present utility model shall be deemed as an infringement of the protection scope of the present utility model.
