Description

The utility model relates to devices for cleaning the surfaces of the needle beds of flat knitting machines, in particular using jets under pressure or spraying [B08B3/00, B08B3/02, B08B13/00].

Known from the prior art is a FULLY AUTOMATIC COMPUTERIZED MACHINE FOR CLEANING THE NEEDLE PLATE OF A FLOOR KNITTING MACHINE [CN210160018, publ. 03.20.2020], characterized in that it includes a working surface for placing the needle plate to be washed, and the working surface is equipped with horizontal and vertical guides. The longitudinally moving water spray head is equipped with an inlet for collecting waste water on the working surface. The washing wastewater flows out from the wastewater collection inlet and is previously treated by a circulating filter device connected to the water spray head. The working surface is a bowl-type working surface, it has two parallel rods located along the X-axis guides, which are equipped with Y-axis guides in the longitudinal direction, and the water spray head is installed on the Y-axis guides and can make reciprocating movements in the longitudinal direction, Driven by the Y-axis servo motor, as well as the Y-axis guide and water spray head can make reciprocating movements in the longitudinal direction, driven by the X-axis servo motor.

Also known is a DEVICE FOR WASHING NEEDLE CLOTH FOR COMPOSITE NEEDLES [JP7204557, publ. 01/16/2023], the operating principle of which is that the needle bed, which is removed from the flat knitting machine and installed in the washing tank of the needle washing device, is washed with a liquid such as washing solution, water, etc., which is ejected from the nozzle. The nozzle is attached to a needle bar, which can move along the surface of the needle bed. The compound needle is placed in the needle groove of the needle bed. While maintaining the position of the slider, a jet of liquid is released from the nozzle into the mortar to drive the needle main body to move the needle main body into the needle groove so that the relative position between the needle main body and the slider is switched to ensure reliable and efficient washing.

The common disadvantages of the above analogues are the stationary placement of the needle bar inside the body, which eliminates the possibility of rotation of the needle bar during washing, as well as the constant distance from the nozzle to the needle bar, which limits the functionality of the device.

Implementation of a utility model.

A vertical type device for washing the needle beds of flat knitting machines consists of a housing (Fig. 1) containing a base 1, a cover 2, side walls 3, a rear wall 4 and doors 5 containing rubber seals 6 and made with the possibility of opening them inside the housing.

An axis 7 is mounted to the base 1 and the cover 2, in the upper and lower parts of which holders 8 of variable length are fixed (Fig. 2), made with the possibility of installing needle beds of various sizes on them. In one embodiment, the axis 7 rotates through the operation of electric motors (not shown in the figures).

Inside the housing, along one of the side walls 3 (Fig. 3 and 4), a vertical guide 9 is mounted, to which a side guide 10 is mounted perpendicularly, made with the ability to move in a vertical plane along the vertical guide 9 by means of the operation of the electric motor of the side guide 11.

A central guide 12 is mounted to the side guide 10, perpendicular to it and parallel to the base 1 and the rear wall 4, and is configured to move in a horizontal plane along the side guide 10 by means of the operation of the electric motor of the central guide 13.

A nozzle 14 is mounted on the central guide 12, connected to a water supply device (not shown in the figures) and configured to move along the central guide 12 by operation of the electric motor of the nozzle 15.

The proposed technical solution works as follows.

The needle bar 16 is placed inside the device for washing the needle bars of flat knitting machines and its end parts are secured to the holders 8 (Fig. 2).

The doors 5 are hermetically closed and the supply of water with detergent under pressure is turned on through the nozzle 14 towards the plane of the needle bar 16.

In various embodiments, the needle bar 16 is rotated by an electric motor or left stationary, and the nozzle 14, by remotely controlling the electric motor 15, is moved along the central guide 12 (Fig. 3 and 4), while the central guide 12, by remotely controlling the electric motors of the central guide 13, is moved to horizontal plane along the side guide 10, and the side guide 10, by remotely controlling the electric motors of the side guide 11, is moved in a vertical plane along the vertical guide 9, and thus the needle bar 16 is washed from contaminants.

If it is not possible to supply power or water to the body of the device for washing the needle beds of flat knitting machines, the needle bed 16 is washed manually using an external washing tool (Fig. 5) supplying water under high pressure.

In this embodiment, the bell of the washing tool 17 is placed inside the housing, the doors 5 are closed (in this case, the seals 6 ensure tightness and prevent water from penetrating through the doors 5 outside the body) and the needle bar 16 is washed manually, moving the bell of the washing tool 17 in the directions required by the operator.

The specified technical result - increasing the efficiency of devices for washing the needle beds of flat knitting machines - is achieved due to the following factors:

making the holders rotatable, which facilitates access of the washing jet of washing liquid to any selected area of the surface of the needle bar, including its rear and end parts;

performing a guide with the ability to move in the direction to the surface of the object being cleaned and back, which provides flexible control of the accuracy of the direction, intensity and coverage area of the cleaning liquid beam;

making doors containing seals, which allows you to organize a sealed, liquid-free manual cleaning using an external washing tool in conditions where there is no possibility of supplying power or water to the device body.

The vertical orientation of the housing helps to improve the performance characteristics of the device in terms of reducing the area required to accommodate the device, as well as in terms of simplifying access to all parts of the needle bar.

In 2023, the applicant produced an experimental prototype of a device for washing the needle beds of flat knitting machines, which was subjected to laboratory and production tests in comparison with a device in regular use, manufactured in accordance with the description of the prototype.

The tests confirmed the advantages in the operating efficiency of the experimental sample compared to the prototype in terms of reducing washing time by 12...14% while achieving equal quality of cleaning the needle bar and reducing washing liquid consumption by 10...12%.

The above embodiments of a device for washing the needle beds of flat knitting machines illustrate, but do not limit the set of all possible embodiments of the utility model.

The proposed device for washing the needle beds of flat knitting machines is a product that has structural integrity and is produced in compliance with the established technological process at the manufacturer.
