Description

Technical Field

[0001] The utility model relates to the technical field of knitting machinery, in particular to a Sanklin component and a hosiery knitting machine having the same. Background Art

[0002] During the production process of hosiery machines, the yarn often hangs too low or even falls to the underside of the needle latch, making it impossible to be effectively clamped and fixed by the needle. As a result, the coil becomes unstable during the subsequent knitting process, easily falling off or deforming, and prone to missed stitches or broken threads, resulting in defects, unevenness or holes on the fabric surface, seriously affecting product quality and production efficiency.

[0003] Chinese patent CN201721007786.5 discloses a knitting machine thread feed mechanism comprising a thread lift assembly, a transport assembly, and a thread feed assembly. The thread lift assembly is located on the knitting machine's feed side and is fixedly connected to the knitting machine. The transport assembly is located on one side of the thread lift assembly, on the knitting machine, and is fixedly connected to the knitting machine. The thread feed assembly is located on the knitting machine's feed side and also on one side of the transport assembly, and is fixedly connected to the knitting machine. The thread feed mechanism provided in this patent uses elastic coils to restrict the thread feed path, uses elastic tube clamps to smooth the fine yarn filaments, and ensures that the thread does not fuzz during transport. The thread is then fed into the device through the thread feed coil, and the input angle is adjusted by an adjustment rod, thereby improving the knitting quality and practical range of the device. However, this patent requires the additional provision of a thread lift frame and thread lift roller, as well as their corresponding connection structure. The thread lift assembly in this patent serves only to carry the transported thread and provide tension, and does not change the thread's hanging position.

[0004] In view of this, this application is hereby filed. Utility Model Content

[0005] The problem solved by the utility model is that in the production process of the existing hosiery knitting machine, the yarn often hangs at a low position or even falls to the lower side of the needle latch, which seriously affects the product quality and production efficiency.

[0006] The technical solution of the present utility model is achieved as follows:

[0007] A sinker assembly is used for a hosiery knitting machine. The sinker assembly includes a sinker track assembly. The sinker track assembly includes an upper track block and a lower track block. The upper track block and the lower track block are arranged relative to each other in a vertical direction. The gap between the upper track block and the lower track block is used to form a sinker track. The sinker track is used to provide a movement trajectory for the sinker. A thread lifting structure is provided between the upper track block and the lower track block. The thread lifting structure is used to enable the sinker to cooperate with the knitting needle of the hosiery knitting machine to guide the knitting thread to a position on the knitting needle close to the middle between the needle hook and the needle tongue.

[0008] The thread lifting structure is used to raise the position of the sinker when hanging the thread, so that it can contact the thread earlier, adjust the tension of the coil to make it more stable, and guide the thread to the correct position to prevent it from falling below the needle tongue, so that the knitting needle can effectively clamp and fix the thread, avoid deformation or falling off of the coil during the weaving process, and avoid defects, unevenness or holes caused by missed stitches or broken threads, thereby improving product quality and production efficiency.

[0009] Furthermore, the wire lifting structure includes a raised portion and a groove portion, the raised portion is arranged on the lower track block, the groove portion is arranged on the upper track block, and the raised portion and the groove portion are arranged correspondingly.

[0010] This setting only requires adding corresponding structures to the upper track block and the lower track block. In actual production, the raised portion is integrally formed with the lower track block, and the groove portion is directly formed on the upper track block. In this case, the number of parts in the hosiery knitting machine is not increased, and the accuracy of the thread hanging can be effectively improved, thereby improving product quality and production efficiency. It is simple and convenient.

[0011] Furthermore, the protrusion and the groove are trapezoidal structures.

[0012] Through the above-mentioned arrangement, the sinker can cooperate with the knitting needle relatively stably when the upper end face of the trapezoid is running to confine the knitting thread between the needle hook and the needle tongue, preventing the knitting thread from falling to the lower side of the needle tongue, so that the knitting thread can be effectively clamped and fixed by the knitting needle, thereby improving the stability of the knitting work, and improving product quality and production efficiency.

[0013] Furthermore, when the protrusion is at zero position, the angle between the protrusion and the needle cutter on the hosiery knitting machine is 60-65 degrees.

[0014] Furthermore, when the protrusion is at zero position, the angle between the protrusion and the needle cutter on the hosiery knitting machine is 63°.

[0015] Through the above arrangement, the position of the sinker is relatively raised when cooperating with the knitting needle to form a loop, thereby effectively guiding the knitting thread to the correct position between the needle hook and the needle tongue, ensuring the smooth progress of subsequent knitting.

[0016] Furthermore, the height of the protrusion is between 2-5 mm.

[0017] Furthermore, the height of the raised portion is 2.3 mm.

[0018] Through the above arrangement, the sinker is at a reasonable height, which effectively increases the height of the weaving thread so that it can be hung between the needle hook and the needle tongue, while also ensuring the safety of pointing to the weaving thread, which is conducive to the smooth progress of subsequent weaving work.

[0019] Furthermore, the width of the raised portion is between 10-13 mm.

[0020] Furthermore, the width of the raised portion is 11.5 mm.

[0021] Through the above arrangement, the position where the sinker and the thread lifting structure rise in coordination can be effectively limited, so that the weaving thread can be hung at an accurate position, thereby ensuring product quality and production efficiency.

[0022] The utility model also discloses a hosiery knitting machine, which comprises the Sanklin assembly as described above.

[0023] The advantages of the hosiery knitting machine over the prior art are the same as those of the Sanklin assembly, which will not be described in detail here.

[0024] Compared with the prior art, the present invention provides a Sanklin assembly and a hosiery knitting machine having the same, which has the following advantages:

[0025] By setting the thread lifting structure in the sinker assembly, the sinker piece can lift the thread to a position close to the middle of the knitting needle when assisting in thread hanging, achieving effective clamping and fixation of the needle on the thread, thereby ensuring that the thread is fully supported and guided during the looping process, preventing the coil from deforming or falling off during the weaving process, and effectively improving the product quality and production efficiency of the fabric. The utility model has a simple structure and does not require the addition of new parts. It effectively improves the accuracy of thread hanging, thereby improving product quality and production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] To make the purpose, technical solutions, and advantages of the present application more clear, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the accompanying drawings in the embodiments of the present application. In the accompanying drawings, components with the same structure or function are marked with the same reference numerals, and their repeated descriptions are omitted.

Therefore, they should not be understood as limiting the scope of protection of this application. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0032] A Sanklin assembly and a hosiery knitting machine having the same according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Example 1

[0034] This embodiment provides a Sinker assembly for a hosiery knitting machine, such as Figure 1 、 Figure 2 As shown, the sinker assembly includes a sinker track assembly, and the sinker track assembly includes an upper track block 100 and a lower track block 200. The upper track block 100 and the lower track block 200 are relatively spaced apart in the vertical direction, and the gap between the two is used to form a sinker track 300. The sinker track 300 is used to provide a motion trajectory for the sinker (not shown in the drawings). A thread lifting structure 400 is provided between the upper track block 100 and the lower track block 200. The thread lifting structure 400 is used to enable the sinker to cooperate with the knitting needle of the hosiery machine (not shown in the drawings) to guide the knitting thread to a position on the knitting needle close to the middle between the needle hook and the needle tongue.

[0035] In the prior art, hosiery knitting machines are generally equipped with a sinker assembly, in which a sinker track 300 is formed to provide a motion trajectory for the sinker. During operation, the sinker cooperates with the knitting needle to achieve thread lifting and coil formation. In this process, the sinker is used to help the thread be correctly positioned on the knitting needle to facilitate coil formation. The thread lifting structure 400 is used to improve the position of the sinker when hanging the thread, so that it can contact the thread earlier, adjust the tension of the coil to make it more stable, and guide the thread to the correct position to prevent it from falling below the needle tongue, so that the knitting needle can effectively clamp and fix the thread, avoid the phenomenon of coil deformation or falling off during the knitting process, and avoid defects, unevenness or holes caused by missed stitches or broken threads, thereby improving product quality and production efficiency. It should be noted that the structure of the sinker and the knitting needle cooperating to guide the thread and the knitting needle including the needle hook and needle tongue are both prior art and will not be repeated here.

[0036] As an embodiment of the present invention, the wire lifting structure 400 includes a protrusion 410 and a groove 420. The protrusion 410 is provided on the lower track block 200, and the groove 420 is provided on the upper track block 100. The protrusion 410 and the groove 420 are provided correspondingly. The corresponding provision of the protrusion 410 and the groove 420 means that the protrusion 410 is provided on a side of the lower track block 200 close to the sinker track 300 and is protruded toward the upper track block 100, and the groove 420 is provided on a side of the upper track block 100 close to the sinker track 300 and is recessed in a direction away from the sinker track 300, and the protrusion 410 and the groove 420 cooperate to form a portion of the sinker track 300. This setting only requires adding corresponding structures on the upper track block 100 and the lower track block 200. In actual production, the protrusion 410 is integrally formed with the lower track block 200, and the groove portion 420 is directly formed on the upper track block 100. In this case, the number of parts in the hosiery knitting machine is not increased, and the accuracy of the thread hanging can be effectively improved, thereby improving product quality and production efficiency. It is simple and convenient.

[0037] As a partially optional embodiment, the protrusion 410 is a trapezoidal structure. Figure 2 As shown, it is arranged along the track surface of the lower track block 200. Through the above arrangement, the sinker can cooperate with the knitting needle relatively stably when running on the upper end face of the trapezoid to confine the knitting thread between the needle hook and the needle tongue, avoiding the knitting thread from falling to the lower side of the needle tongue, so that the knitting thread can be effectively clamped and fixed by the knitting needle, thereby improving the stability of the knitting work, and improving product quality and production efficiency.

[0038] Specifically, when the raised portion 410 is at the zero position, the angle between it and the needle cutter on the hosiery machine is 60-65 degrees. Preferably, when the raised portion 410 is at the zero position, the angle between it and the needle cutter on the hosiery machine is 63 degrees. The needle cutter is a heel needle cutter. The specific structure and installation position of the heel needle cutter belong to the existing technology, and this application does not improve the heel needle cutter. The zero position is also the existing technology in the hosiery machine and will not be described in detail here. Through the above-mentioned arrangement, the position of the sinker is relatively raised when cooperating with the knitting needle to form a loop, thereby effectively guiding the yarn to the correct position between the needle hook and the needle tongue, ensuring the smooth progress of subsequent knitting.

[0039] In a preferred embodiment of this embodiment, the height of the raised portion 410 is between 2 and 5 mm. Preferably, the height of the raised portion 410 is 2.3 mm. The height of the raised portion 410 refers to the vertical distance between the bottom surface of the raised portion 410 where it connects to the lower track block 200 and the top surface of the raised portion 410. The movement trajectory and position of the sinker plate have a significant impact on yarn introduction and loop formation. During the knitting process, the sinker plate must work closely with the needles to ensure that the yarn is woven into the fabric at the correct position. If the sinker plate is positioned too low, it cannot effectively control loop tension and cannot guide the yarn to the correct position between the needle hook and the needle latch. If the sinker plate is positioned too high, it will cause excessive loop tension and may even damage the needles or fabric. This arrangement ensures that the sinker plate is at a reasonable height, effectively raising the yarn height so that it can be hooked between the needle hook and the needle latch, while also ensuring secure thread guidance, facilitating smooth subsequent knitting.

[0040] In this embodiment, the width of the raised portion 410 is between 10-13 mm. Preferably, the width of the raised portion 410 is 11.5 mm. It should be understood that the raised portion 410 is arranged along the track surface of the lower track block 200. Since the projection of the track surface on the horizontal plane is a circular ring, the projection of the raised portion 410 on the horizontal plane is an arc. After the arc-shaped raised portion 410 is stretched, its shape is a trapezoid. The width of the raised portion 410 is the length of the chord connecting the two ends of the projection of the bottom arc line of the raised portion 410 close to the radial outside of the track surface on the horizontal plane. Through the above-mentioned arrangement, the position of the rising and falling pieces in conjunction with the lifting structure 400 can be effectively limited, so that the weaving thread can be hung in an accurate position, ensuring product quality and production efficiency.

[0041] As one optional embodiment, the top width of the raised portion 410 is between 4 and 7 mm. Preferably, the top width of the raised portion 410 is 5.5 mm. It should be understood that the top width of the raised portion 410 is the length of the chord connecting the two ends of the horizontal projection of the arc line of the top end of the raised portion 410, which is close to the radially outer side of the track surface. Through the above arrangement, the sinker can maintain a stable height at a certain distance when assisting the knitting needles in looping, thereby stably guiding the yarn into the position between the needle hook and the needle tongue, providing a guarantee for the subsequent knitting quality.

[0042] Preferably, the connection points between the bottom ends of the raised portion 410 and the lower track block 200 are smoothly transitioned through arcs, and the two corners of the top of the raised portion 410 are also smoothly transitioned through arcs. This arrangement ensures the smooth movement of the sinker, allowing the hosiery knitting machine to operate stably.

[0043] It should be noted that the groove portion 420 corresponding to the protrusion 410 is also a trapezoidal structure, and its corresponding position and size relationship are also set corresponding to the protrusion 410, so that the sinker can move smoothly.
