Description

Shearing device of circular towel knitting machine

technical field

The utility model relates to a shearing device, in particular to a shearing device of a circular knitting towel knitting machine, which enables the knitting terry cloth and shearing operations to be completed together and improves the working efficiency of the knitting machine.

Background technique

Generally, the shearing operation of terry cloth is usually first knitted into terry cloth on a circular knitting machine, and then the cloth is placed on another shearing machine for shearing operation. This operation method is not only cumbersome, but also inefficient. It is to cut off the top part of the pile weave (please refer to Figure 7-2), which not only causes material loss, but also needs to be trimmed many times to achieve the neat effect of pile piles with the same length, so the cost is too high and it is very expensive. not ideal.

Therefore, in order to improve the above shortcomings, some people in the industry have developed a machine that can perform shearing operations while knitting terry cloth. For example, China Taiwan New Patent Announcement No. 208294, it is provided with an inclined plane below the groove of the raising needle. The knife blade cuts off the old loop under the groove while the raising needle rises and the knitting needle hooks the yarn to weave a new loop, so as to achieve the purpose of shearing. Although this method can achieve the effect of shearing, however The yarn has a certain degree of toughness, and it is easy to wear the blade during operation, so it cannot be replaced frequently after long-term use. There are also some manufacturers who have developed two pieces of sliver sheets with different structures, such as China Taiwan New Patent Announcement No. 235625 patent, it is to utilize two raw gram sheets to advance and press the yarn while cutting off the old loops on the raising needles in the mode of clipping, to achieve the purpose of shearing, although this kind of structure is also It can achieve the effect of shearing, but because two different structures of sliver have to be placed in the sliver slot sequentially, the pre-work before knitting fabric is very troublesome, and the precision control of the sliver is difficult and timely. Its structure is relatively complicated, which is easy to cause failure or cannot completely cut off the long and short hairs that have been "missed".

Utility model content

The main technical problem to be solved by the utility model is to overcome the above-mentioned defects existing in the prior art, and provide a shearing device of a circular knitting towel knitting machine. After looping, the raising needle is lowered to pull down the loop with its groove, and then the yarn cutter is advanced to penetrate into the cutting opening of the raising needle, and then the loop is cut off to achieve the purpose of shearing.

The technical scheme that the utility model solves its technical problem adopts is:

A shearing device of a circular knitting towel knitting machine, characterized in that the front end of the raw gram sheet is provided with a thinner blade to form a cutting knife, and a through cutting hole is set at a proper position on the top of the raising needle, when the knitting needle When the hook pulls the yarn to weave the terry cloth surface, a terry loop will be formed in the groove of the raising needle, and then the yarn cutter is advanced so that the blade penetrates into the burr opening of the raising needle, and the loop yarn on the raising needle is cut off at the same time thread, so that the knitting needle and hook can weave the terry cloth surface and shear the wool together.

In the shearing device of the aforementioned circular knitting towel knitting machine, the blade angle of the yarn cutter is designed to be 90 degrees vertically, which is a better implementation angle.

Compared with the existing technology, the beneficial effect of the utility model is that the structure is simple, and there will be less failure during operation, and the terry can be easily cut off without causing wear and tear on the parts, so that the knitting terry cloth and shearing operations can be Complete together, improve the working efficiency of the knitting machine.

Detailed ways

Please refer to Fig. 1-3, the basic components of the utility model are the same as those of a general circular knitting towel knitting machine. It enters the groove of the raw gram cylinder 8, and its movement trajectory is controlled by the yarn cutter triangle 6. The raising needle 2 is provided with a through cutting hole 21 at an appropriate position on its top, and a plurality of raising needles 2 The knitting needles 3 are respectively placed in the grooves of the upper needle cylinder 71, and their movement trajectories are also controlled by the upper triangle 4. control.

With the above-mentioned components, please refer to 4-6. When the raising needle 2 rises, the knitting needle 3 advances the hooked yarn and the ground yarn for knitting, and a pile loop will be formed in the groove 23 of the raising needle 2. At this time, the raising needle 2 is lowered and the loop is pulled down by the upper edge of the groove 23 to make the loop tight, and then the yarn cutter 1 is advanced to penetrate into the cutting edge 21 of the raising needle 1 with its blade 11, and then The loop is cut off to complete the shearing action. Repeat this action to knit the looped cloth surface with 3 hooks of the knitting needle and complete the shearing operation together.

It is worth mentioning that, when the utility model device pulls down the pile loop by the upper edge of the raising needle 2 through its groove 23, the yarn of the pile loop is tightened on the end surface of the cut wool 21, so when the yarn cutter 1 When the blade 11 of the yarn cutter touches the loop, the loop can be cut off effortlessly, and the blade 11 of the yarn cutter 1 will not be worn out. If the blade 11 is not sharp due to long-term use, the blade can be removed and re-sharpened 11 openings, so it can be used repeatedly without frequent replacement of the yarn cutter. It will not cause material loss after shearing with a shearing machine.

The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the utility model, All still belong to within the scope of the technical solution of the utility model.

In summary, the utility model fully meets the needs of industrial development in terms of structural design, practicability and cost-effectiveness, and the disclosed structure also has an unprecedented innovative structure, novelty, creativity and practicability, and meets the needs of industrial development. According to the requirements of the new patent requirements, the application is filed in accordance with the law.
