Description

Technical Field

[0001] The present invention relates to the technical field of flat knitting machines, in particular to a garment flat knitting machine. Background Art

[0002] The computerized flat knitting machine is a double-needle plate latch needle weft knitting machine. The general knitting process is as follows: during the rising process of the knitting needle, the coil gradually withdraws from the needle hook, opens the needle latch, and withdraws the needle latch to hang on the needle bar; during the descending process of the knitting needle, the needle hook hooks the newly placed yarn and pulls and bends it into a coil, while the original coil is removed from the needle hook, and the new coil passes through the old coil and is connected in series with the old coil. The coil strings formed by numerous knitting needles are connected to each other to form a woven fabric. During knitting, in order to prevent the coil in the needle hook from rising with the rising of the knitting needle, that is, to prevent the coil from floating up, a pulling device is usually installed on the computerized flat knitting machine to continuously pull the woven fabric downward.

[0003] There are usually two types of pulling devices on existing computer flat knitting machines. One is a roller roller assembly symmetrically arranged front and back. When working, two symmetrical roller rollers with opposite rotation directions are used to clamp the fabric and pull it downward. It is used for fabrics that need to be pulled as a whole, such as a single piece of ordinary fabric; the other is based on the former, and a hook assembly is installed under the roller roller assembly. It is used for fabrics that need to be pulled locally, such as two-piece ready-made clothes. For example, when knitting sweaters, in order to achieve a scooped collar and inverted shoulders, it is necessary to locally pull the collar and shoulders of the sweater, which have inconsistent front and back lengths; in actual production, the above two types of computer flat knitting machines can only produce corresponding types of fabrics. For production companies, if they want to produce multiple types of fabrics, they can only establish corresponding production lines and purchase corresponding equipment. This not only increases the company's initial equipment investment costs, but also increases the company's land costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a garment knitting machine that can realize multiple uses and be converted into different modes according to actual production needs, thereby reducing production costs.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a garment knitting machine, comprising a pull-down mechanism, a pulling mechanism installed below the pull-down mechanism, and a lifting mechanism coordinated with the pulling mechanism, wherein the lifting mechanism can drive the pulling mechanism to move obliquely upward or obliquely downward relative to the pull-down mechanism; when the garment knitting machine is used to produce woven fabrics that require local pulling, the pulling mechanism will move to directly below the pull-down mechanism, and at this time the pull-down mechanism and the pulling mechanism operate in coordination; when the garment knitting machine is used to produce woven fabrics that require overall pulling, the pulling mechanism will move to obliquely below the pull-down mechanism until the pull-down mechanism and the pulling mechanism do not interfere with each other.

[0006] Furthermore, the pull-down mechanism includes symmetrically arranged clamping rollers.

[0007] Furthermore, the pulling mechanism includes a lifting frame that cooperates with the lifting mechanism.

[0008] Furthermore, the lifting mechanism includes a mounting plate, a driving device, a lifting device, and a sliding device that cooperates with the lifting device.

[0009] Furthermore, the mounting plate is provided with an arc-shaped sliding groove that cooperates with the lifting device.

[0010] Furthermore, the lifting device includes a rotating gear matched with the driving device, a lifting assembly matched with the lifting frame, and a transmission connecting rod connecting the lifting assembly and the rotating gear.

[0011] Furthermore, the transmission connecting rod is provided with a pulley that matches the arc-shaped sliding groove.

[0012] Furthermore, the lifting assembly includes a lifting rod matched with the lifting frame, a lifting block matched with the transmission connecting rod, and a lifting sleeve matched with the lifting block and the lifting rod.

[0013] Furthermore, the lifting frame is provided with a mounting position that matches the lifting rod and the lifting sleeve.

[0014] Furthermore, the sliding device includes a sliding seat and a sliding rod that cooperate with the lifting rod and the lifting block.

[0015] The beneficial effects of the present invention are:

[0016] The present invention provides a garment knitting machine, in which the pulling mechanism can move obliquely upward or downward relative to the pulling mechanism under the drive of the lifting mechanism, and the pulling mechanism can be adjusted to different positions according to needs. It can not only produce single-piece ordinary fabrics (that is, woven fabrics that need to be pulled as a whole) but also produce double-piece garments (that is, woven fabrics that need to be pulled locally), and can freely switch between the two modes according to actual production needs, realizing dual-purpose or even multi-purpose of one machine, and can produce different types of woven fabrics on one production line, which greatly improves production efficiency while saving the company's initial investment cost for equipment and land cost.
