Description
Technical Field
[0001] The utility model belongs to the technical field of flat knitting machines, and in particular relates to a sinker, an insert, a tooth gap piece and a tooth gap structure. Background Art
[0002] On a computerized flat knitting machine, the sinker, the serration plate, and the insert are three separate components, each with distinct functions. The sinker primarily serves to pull and control the position of the loops and prevent yarn from floating, while the serration plate works in conjunction with the sinker to ensure accurate yarn guidance and tension control during the loop formation process. The insert primarily protects the needle bed and ensures precise needle movement.
[0003] With the development of knitting technology, the requirements for fabric density and precision are constantly increasing. The independent sinkers, tooth plates and inserts in the existing computer knitting machines are gradually showing some limitations when meeting higher standards of production requirements, especially on fine-gauge knitting machines. The existence of three independent components takes up a large space. Utility Model Content
[0004] The purpose of the utility model is to provide a sinker, an insert, a tooth gap plate and a tooth gap structure. The structure reduces the required space occupation by combining the functions of the sinker and the tooth gap plate, thereby making the thickness arrangement of the needle bed parts on the fine-gauge flat knitting machine more reasonable, enhancing the performance of each part and extending its service life.
[0005] In order to achieve the above technical purpose, the technical solution of the utility model is:
[0006] A sinker comprises a needle clock and a mounting hole. When the needle clock is driven by a cam, the sinker moves around the mounting hole. The sinker head has a loop-forming surface, and a line-pressing flange is provided above the loop-forming surface.
[0007] During knitting, the sinker cam controls the needle clock, driving the sinker to rotate about the mounting hole. When the sinker rises, the knitting needle hooks the yarn and ensures that the loop is formed on the loop-forming surface of the sinker, thus fulfilling the function of the tooth plate. When the sinker descends, the yarn hanging on the loop-forming surface of the sinker is pressed by the thread pressing flange and moves downward, allowing the loop to smoothly exit the loop-forming surface and prevent the loop from floating. In this way, the functions of the existing sinker and the tooth plate are integrated, so that the sinker only occupies one space in the original tooth plate or sinker, but can simultaneously perform the full functions of both. This is conducive to meeting the space requirements of fine-gauge flat knitting machines, and can also make the thickness arrangement of needle bed components on fine-gauge flat knitting machines more reasonable, thereby enhancing the performance of each component and extending its service life. In addition, because the loop is directly formed on the loop-forming surface of the sinker, when the sinker is pressed down, the loop naturally moves downward with the sinker. Then, in conjunction with the thread pressing flange, when the sinker is pressed to the bottom dead center, the loop naturally slides off the loop-forming surface. When the cloth piece is under the action of gravity and the pull of the lower winding cloth, the coil on the loop forming surface will no longer be stretched upward when the sinker rises, thus ensuring the stability of the second loop forming.
[0008] Specifically, the coil-forming surface is arc-shaped, and the arc-shaped coil-forming surface can better fit the coil, making it easier for the auxiliary flange to enter the coil and perform secondary extrusion on the coil.
[0009] Furthermore, the coil-forming surface is provided with an auxiliary flange. When the sinker moves up and down, the auxiliary flange can squeeze the coil again, making it easier for the coil to slide downward. Moreover, by controlling the range of the sinker's up and down movement, the auxiliary flange can selectively peel the coil from the spikes, allowing the coil to be transferred between the spikes.
[0010] In order to improve the stability of the sinker in lifting and lowering, a guide arc groove is opened on the head of the sinker. The circle of the guide arc groove is at the same point as the rotation center of the sinker. During installation, a shaft is passed through the guide arc groove and cooperates with the insert slot on the needle plate. When the sinker rotates around the mounting hole, the shaft slides in the guide arc groove, and the sinker can move up and down stably.
[0011] The utility model provides an insert, which comprises a mounting shaft hole and a front end surface of the insert is provided with a plurality of downwardly inclined spikes.
[0012] The insert is installed on the needle bed through the mounting shaft hole. During knitting, since the yarn is looped on the loop-forming surface, the coil will be tightly wrapped on the loop-forming surface of the sinker. The coil pressed down by the sinker can pass through the spikes (barbs) from top to bottom. The spikes (barbs) hook the coil, so that the coil can only slide down from top to bottom. In the case of no coil and no tension, such as when the cloth roller loses tension, the yarn is broken and the cloth is re-woven after falling, the front and back pieces are knitted separately, and during partial knitting, the spikes (barbs) can ensure that the coil does not float up, which is convenient for the next row of knitting.
[0013] A tooth mouth structure includes an insert and a sinker, the sinker includes a wire pressing flange and a coiling surface respectively arranged on the head of the sinker, the coiling surface is located below the wire pressing flange, the sinker is respectively provided with a needle clock and a mounting hole, when the needle clock is driven by a triangle, the sinker rotates around the mounting hole; the insert is provided with a mounting shaft hole, the front end surface of the insert has a plurality of downwardly inclined spikes; the coiling surface of the sinker corresponds to the front end surface of the insert, when the sinker sinks, the coil pressed down by the wire pressing flange passes through the spikes from top to bottom, and the spikes pull the coil thereon to prevent it from floating.
[0014] The sinker and insert are installed on the needle bed through the mounting hole and the mounting shaft hole respectively. During knitting, the sinker triangle controls the needle clock to drive the sinker to rotate around the mounting hole. When the sinker rises, the knitting needle hooks the yarn and smoothly forms a loop on the loop-forming surface of the sinker. When the sinker descends, the yarn hanging on the loop-forming surface of the sinker is pressed by the thread pressing flange and moves downward, so that the looped coil can smoothly exit the loop-forming surface and avoid the coil floating up. In this way, the functions of the sinker and the tooth plate can be integrated into one, so that the sinker only occupies one space position in the original tooth plate or sinker, but can realize all the functions of both at the same time, thereby meeting the space requirements of the fine-gauge flat knitting machine, and making the thickness arrangement of the needle bed parts on the fine-gauge flat knitting machine more reasonable, thereby enhancing the performance of each part and extending its service life.
[0015] In addition, through the composition of the sinker and the spiked insert, when the cloth roller loses tension, the broken yarn falls and the cloth is re-woven, the front and back pieces are woven separately, and during partial weaving, the yarn is looped on the sinker. At this time, the spiked insert pierces the coil, so that the coil can only slide down from top to bottom, which can ensure that the coil does not float up in the absence of tension, facilitating the next row of weaving.
[0016] The sinker provided by the present invention integrates the functions of an existing sinker and a tooth-gap piece. When using a sinker in the prior art, the corresponding functions can also be achieved by changing the structure of the tooth-gap piece. Specifically, the present invention provides a tooth-gap piece including a connecting shaft hole, and the front end of the tooth-gap piece has a plurality of downwardly inclined spikes. The spikes also function to hook the coil so that the coil can only slide down from top to bottom. When there is no coil and no tension, the spikes (barbs) can prevent the coil from floating, facilitating the next row of knitting.
[0017] The utility model integrates the functions of the sinker and the tooth plate into one, which can not only give full play to the functions of the two but also save space, optimize the thickness layout of each part on the needle bed of the fine-gauge flat knitting machine, improve the utilization efficiency of each part, and effectively extend its service life; and through the combination of the sinker and the inlay with spikes, the coil can be further prevented from floating up, which facilitates the knitting action of the next row.

[0022] Reference Figures 1 to 3 , a tooth mouth structure, including an insert 8 and a sinker 1. In this embodiment, the head of the sinker 1 is close to the needle tongue side, and the tail of the sinker 1 is close to the triangle side.
[0023] Specifically, a wire pressing flange 2 and a ring forming surface 3 are respectively provided at the head of the sinker 1. The wire pressing flange 2 and the sinker 1 are integrally formed. The ring forming surface 3 is located below the wire pressing flange 2 and is arc-shaped. The wire pressing flange 2 is inclined downward, and the bottom of the wire pressing flange 2 and the top of the ring forming surface 3 constitute a wire pressing arc surface 10. The tail of the sinker 1 is respectively provided with a needle clock 4 and a mounting hole 7. When the needle clock 4 is driven by a triangle, the sinker 1 rotates around the mounting hole 7; in other embodiments, the mounting hole 7 can be an arc-shaped groove that can enable shaft parts to be installed.
[0024] In the middle of the loop-forming surface 3 , there is an arc-shaped auxiliary flange 5 on the loop-forming surface 3 .
[0025] A guide arc groove 6 is provided on the head of the sinker 1 , and the guide arc groove 6 extends from a side close to the wire pressing flange 2 to a side close to the bottom of the coil forming surface 3 , and the circle where the guide arc groove 6 is located is cocentric with the mounting hole 7 .
[0026] The front end surface of the insert 8 corresponds to the loop-forming surface 3 of the sinker 1. The front end surface of the insert 8 is provided with a plurality of spikes 9, which are serrated. The spikes 9 are integrally formed with the insert 8, and the heads of the spikes 9 are arranged downward. The insert 8 is provided with a mounting shaft hole 11. In other embodiments, a toothed piece or component with its front end made into a barb can also achieve this function.
[0027] During knitting, the sinker 1 rises, allowing the knitting needle to hook the yarn and smoothly form a loop on the looping surface 3 of the sinker 1. Then the sinker 1 drops, and the yarn hanging on the looping surface 3 of the sinker 1 is pressed by the thread pressing flange 2 and moves downward. Under the action of the gravity of the cloth and the tension of the lower winding cloth, the looped coil is smoothly withdrawn from the looping surface 3. The sinker 1 drops, and the yarn hanging on the looping surface 3 of the sinker 1 is pressed by the thread pressing flange 2 and moves downward, so that the looped coil is smoothly withdrawn from the looping surface 3. At the same time, when the sinker 1 rises again, the spikes 9 on the inlay 8 hook the coil to prevent the coil from floating.
[0028] When the sinker 1 and insert 8 are not used, and the sinker and insert in the prior art are used, the tooth plate of the utility model can be used, which includes a connecting shaft hole, and the front end surface of the tooth plate has a plurality of downwardly inclined spikes (the structure is the same as Figure 3 The spikes 9 on the front end of the middle panel 8 also have the function of hooking the coil so that the coil can only slide down from top to bottom. When there is no coil and no tension, the spikes (barbs) can ensure that the coil does not float, making it easier to knit the next row.
[0029] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
