Description

Technical Field

[0001] The utility model relates to the field of knitting equipment, in particular to a lower needle cylinder for an automatic velvet cutting machine. Background Art

[0002] The velvet cutting machine, also known as the loop velvet cutting machine, cuts the terry loops of textiles during weaving, so that the surface of the fabric is covered with smooth velvet. The velvet cutting machine can cut velvet on both sides, or cut velvet on one side and keep the other side as terry loops, or cut velvet partially to form a pattern of velvet loops coexisting and lining each other. The characteristics of the velvet cutting machine are that the textiles become soft and comfortable to use, and have stronger moisture absorption and softness than ordinary textiles.

[0003] The patent document with the patent number of CN214736465U discloses a lower needle cylinder of a long-pile knitting machine, which is characterized in that: the outer peripheral surface of the lower needle cylinder is formed with a plurality of first needle grooves and a plurality of second needle grooves extending vertically and arranged circumferentially, the first needle grooves and the second needle grooves are arranged alternately, the first needle grooves are movably provided with lower knitting needles, and the second needle grooves are movably provided with knife-hook combination needles;

[0004] The following deficiencies still exist in its practical application: as the use time of the velvet cutting machine increases, dust and lint are easily accumulated in the needle groove. Therefore, in order to ensure the stability and efficiency of the machine, the operator needs to regularly check and clean the needle groove. The existing cleaning method usually uses an air gun for blowing, which easily causes dust and lint to fly to other parts of the equipment, and the cleaning effect is poor; at the same time, the processing of the traditional needle barrel mouth is to directly mill the groove on the needle barrel steel material, and then harden it through quenching, and polish it with a steel brush. In this way, the hardness of the barrel mouth cannot be achieved and the hardness is uneven. In particular, some strongly acidic fabrics are prone to wear of the barrel mouth, resulting in an increase in the defective rate of the fabric, and the coil surface is prone to fuzzing and damage. When one of the milling grooves is damaged, the entire needle barrel needs to be replaced, and the maintenance cost is high. Utility Model Content

DETAILED DESCRIPTION

[0030] In order to make the embodiments of the utility model, all belong to the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but only represents the selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] In the description of the present utility model, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as referring to the purpose, technical solutions and advantages of the methods. To be clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, not all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work indicate or imply relative importance or implicitly indicate the number of indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0032] As the existing velvet cutting machine is used for a longer time, the knitting needle groove is prone to accumulate dust and lint. Therefore, in order to ensure the stability and efficiency of the machine, the operator needs to regularly check and clean the knitting needle groove. The existing cleaning method usually uses an air gun for blowing, which easily causes dust and lint to fly to other parts of the equipment, and the cleaning effect is poor; at the same time, the processing of the traditional needle barrel mouth is directly milling grooves on the needle barrel steel material, and then hardened by quenching, and polishing is also rolling polishing with a steel brush. In this way, the hardness of the barrel mouth cannot be achieved and the hardness is uneven. In particular, some strongly acidic fabrics are prone to wear of the barrel mouth, resulting in an increase in the defective rate of the fabric, and the coil surface is prone to linting and damage. When one of the milling grooves is damaged, the entire needle barrel needs to be replaced, and the maintenance cost is high. In order to solve the above technical problems, this case proposes the following technical solutions:

[0033] Reference Figures 1 to 9 As shown, a lower needle cylinder for an automatic velvet cutting machine, the structure of which includes: a lower needle cylinder body 1, a plurality of inserting pieces 2 arranged on the outer peripheral surface of the lower needle cylinder body 1, the outer periphery of the lower needle cylinder body 1 is evenly provided with a plurality of inserting piece grooves 11 arranged vertically and in parallel, the inserting piece 2 includes a first inserting piece 21 arranged in the inserting piece groove 11, and a second inserting piece 22 close to the outer peripheral surface of the lower needle cylinder body 1 and aligned and connected below the first inserting piece 21, the gap between two adjacent first inserting pieces 21 is a knitting needle groove, the spacing of the knitting needle groove is the same as the thickness of the first inserting piece 21 and the second inserting piece 22, the side of the second inserting piece 22 away from the lower needle cylinder body 1 is also provided with a mounting seat 23 for connecting the second inserting piece 22 in series, the mounting seat 23 is provided with a bolt hole 24 connected with the large plate gear of the velvet cutting machine; the lower needle cylinder body 1 is also provided with a detachable cylinder mouth steel sheet 3 at the cylinder mouth;

[0034] Therefore, when it is necessary to clean the dust and fluff in the needle groove of the lower needle cylinder of the velvet cutting machine, the bolts of the bolt holes 24 on the mounting seat 23 are unscrewed to make the mounting seat 23 active, and then the second plug-in piece 22 is driven by the mounting seat 23 to lean against the outer circumference of the lower needle cylinder body 1 and rotate leftward. At this time, the top of the second plug-in piece 22 is separated from the first plug-in piece 21. At the same time, when the second plug-in piece 22 is aligned with the knitting needle groove and stuck in the bottom of the knitting needle groove, the mounting seat 23 is driven to move upward, so that the dust and fluff accumulated in the knitting needle groove are scraped upward by the second plug-in piece 22, which can effectively avoid the situation that the dust and fluff fly to other parts of the equipment due to air gun cleaning, and the cleaning efficiency is high. After cleaning, the second plug-in piece 22 is aligned and installed to the bottom of the first plug-in piece 21, and the mounting seat 23 is connected to the large disc gear by bolts, which is simple to operate.

[0035] In addition, a detachable tube mouth steel sheet 3 can be used, and a steel sheet made of a specific material can be selected for installation according to the properties of the knitted material, thereby avoiding wear of the tube mouth by strongly acidic fabrics, improving the quality of the finished fabric, and when one of the steel sheets is damaged, it can be removed and replaced separately, thereby reducing the equipment maintenance cost.

[0036] Furthermore, in order to ensure that the second plug-in piece 22 is installed in place and stably connected to the first plug-in piece 21, a first connecting section 221 and a second connecting section 222 are sequentially provided on the top of the second plug-in piece 22 along the circumference of the lower syringe body 1, and the first connecting section 221 and the second connecting section 222 are distributed in a stepped manner; the bottom of the first plug-in piece 21 is respectively provided with a first protrusion 211 and a second protrusion 212 corresponding to the first connecting section 221 and the second connecting section 222. Therefore, during installation, the first connecting section 221 of the second plug-in piece 22 is close to the first protrusion 211, and the second connecting section 222 is close to the second protrusion 212. At the same time, since the first protrusion 211 and the second protrusion 212 are also arranged in this stepped manner, they can play a limiting role to prevent the second plug-in piece 22 from being positioned, thereby further improving the stability of the connection between the first plug-in piece 21 and the second plug-in piece 22.

[0037] Among them, the tops of the first connecting section 221 and the second connecting section 222 are provided with inclined surfaces that gradually tilt downward from the inside to the outside. Therefore, when the mounting seat 23 drives the second plug-in piece 22 to move upward to scrape off the dirt in the knitting needle groove, the scraped dirt is discharged outward along the inclined surface, avoiding the accumulation of dirt on the top of the second plug-in piece 22, which requires more physical strength when scraping.

[0038] In addition, the mounting seat 23 is provided with a clearance groove 25 located between two adjacent second inserts 22 and corresponding to the knitting needle groove. The clearance groove 25 is connected to the bottom of the knitting needle groove, thereby ensuring that the knitting needle can move up and down and avoiding collision between the knitting needle and the mounting seat 23 during operation.

[0039] Furthermore, in order to facilitate the installation of the first plug-in piece 21, two trapezoidal grooves are provided in sequence from top to bottom on the side of the first plug-in piece 21 facing the lower syringe body 1, and a trapezoidal platform matching the trapezoidal groove is provided in the plug-in piece slot 11. Therefore, during the installation process, the first plug-in piece 21 is aligned with the plug-in piece slot 11, and the trapezoidal groove of the first plug-in piece 21 is correspondingly connected to the trapezoidal platform in the plug-in piece slot 11, which is simple to operate.

[0040] At the same time, the second plug-in piece 22 on the outer periphery of the lower needle cylinder body 1 is composed of six mounting seats 23 connected in series, and gaps are formed at both ends of two adjacent mounting seats 23, and the size of the gap is the spacing of the knitting needle groove. Therefore, when cleaning, one mounting seat 23 can be removed separately for descaling according to the cleanliness of different parts of the lower needle cylinder. When any mounting seat 23 drives the second plug-in piece 22 to rotate, there is enough gap to ensure that the second plug-in piece 22 is aligned with the knitting needle groove after rotation, thereby scraping off the dirt in the corresponding knitting needle groove.

[0041] Specifically, a plurality of limiting steps 12 aligned with the insert slot 11 are evenly arranged on the barrel mouth of the lower syringe body 1, and a placement slot 13 is formed between two adjacent limiting steps 12, and a barrel mouth steel sheet 3 is arranged in the placement slot 13, and a fixing groove 31 matching the placement slot 13 is arranged on the side of the barrel mouth steel sheet 3 facing the lower syringe body 1. Therefore, during installation, the special glue for the circular machine insert is applied to the surfaces of the placement slot 13 and the fixing groove 31 respectively, and then the fixing groove 31 of the barrel mouth steel sheet 3 is connected to the placement slot 13. When the barrel mouth steel sheet 3 is worn by the strongly acidic fabric, the damaged barrel mouth steel sheet 3 can be replaced separately to reduce the replacement cost. At the same time, the steel sheet can be made of special hardness material and can be removed and processed separately. The syringe mouth is smoother and more delicate through vibration grinding, so that the syringe mouth remains smooth and wear-resistant for a long time, and the fabric coil is less worn and preserved more completely.

[0042] In addition, an extended protrusion 32 is also provided on the top of the tube mouth steel sheet 3, which can make the plush coil and the plush yarn coil fit more closely, and the weaving and undoing are smoother, which greatly reduces fabric defects and raw material loss.

[0043] The lower needle cylinder body 1 is evenly distributed with dust removal holes 14 penetrating both sides of the lower needle cylinder body 1 near the cylinder mouth, so as to collect dirt in the knitting needle groove through the dust removal holes 14 .

[0044] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
