Description

Technical Field

[0001] The present application belongs to the technical field of circular knitting machine equipment, and in particular relates to a circular knitting machine with a dust collection function. Background Art

[0002] Circular knitting machines, also known as circular weft knitting machines (or circular weft knitting machines), have developed rapidly due to their multiple loop forming systems (referred to in the industry as the number of yarn feed paths or loop forming paths, or simply paths), high speed, high output, fast pattern changes, good fabric quality, fewer steps, and strong product adaptability.

[0003] The existing foreign patent with publication number KR102590626B1 discloses a large circular knitting machine with a dust collection function, including: a circular table, a plurality of knitting needles arranged inside the circular table, a yarn guide for supplying yarn to the knitting needles through a yarn guide arranged on the upper side of a plurality of knitted fabrics, a needle and a knitting needle, a cam holder, a cylinder accommodated in a needle groove, a control cam opposite to the cylinder to control the knitting needles, and a cam ring supporting the cam holder; the dust collection unit is arranged around the outer periphery of the yarn guide, has a suction port formed in a direction opposite to the yarn guide, and collects foreign matter scattered around the yarn guide.

[0004] The above circular knitting machine collects fluff and other flying catkins through a dust collecting unit, and the dust collecting unit can be opened for easy maintenance, etc. However, the dust collecting units need to be opened manually one by one, which is inefficient. Improvements are made to this problem. Summary of the Invention

[0005] The purpose of this application is to address the above-mentioned technical problems and provide a circular knitting machine with a dust collection function, which can collect flying fluff and other fluff and is easy to open quickly for maintenance.

[0006] The present application provides a circular knitting machine with a dust collection function, comprising a circular knitting machine body, wherein the circular knitting machine body comprises:

[0007] A suction assembly, comprising a plurality of suction chambers evenly distributed in a circle;

[0008] Suction seat, installed on the circular knitting machine body;

[0009] A vacuum suction unit connected to the suction assembly;

[0010] An adjusting mechanism is installed between the suction seat and the suction assembly;

[0011] A rotary connector is mounted on the suction seat and is movably connected to the suction chamber;

[0012] Wherein, the adjustment mechanism is used to drive the suction chamber to rotate, and the suction chamber is provided with a suction port.

[0013] Several suction chambers are evenly distributed in a circle and hinged on the suction seat. The suction chambers are connected to the vacuum suction unit, so that the suction port of the suction chamber generates suction, sucks up the fluff and other flying catkins floating in the air and collects them, thereby improving the environment in the working space. When the suction assembly needs to be opened for maintenance of the circular knitting machine body, the suction chamber is driven to rotate outward through the adjustment mechanism to improve the efficiency of opening the suction chamber and reduce labor intensity. The rotating connector is used to connect the suction chamber and the vacuum suction unit. The rotating connector is movably connected to the suction chamber to ensure stable transmission of suction pressure when the suction chamber rotates.

[0014] Furthermore, the regulating mechanism includes:

[0015] The teeth are placed on a plurality of the suction chambers;

[0016] a gear, mounted on the suction seat and corresponding to the tooth portion;

[0017] A driving device is installed on the suction seat and is connected to the gear;

[0018] A connecting assembly is installed between two adjacent suction chambers, and the connecting assembly is used to control the simultaneous rotation of the suction chambers;

[0019] Wherein, the suction seat is provided with a limiting portion corresponding to the tooth portion.

[0020] The tooth portion is placed on the suction chamber, and the axis of the tooth portion is the same as the rotation axis of the suction chamber. The gear is engaged with the tooth portion. When the driving device drives the gear to rotate, the suction chamber is rotated. 2-4 suction chambers on the suction assembly are equipped with tooth portions, and all the suction chambers are connected through the connecting assembly. When multiple driving devices are driven at the same time, the suction chambers on the suction assembly are controlled to rotate and open at the same time, thereby further improving the opening efficiency of the suction chamber. The rotation stroke of the suction chamber is limited by the limit portion to control the position of the suction chamber in the working and open states.

[0021] Furthermore, the connection component includes:

[0022] A connecting sleeve, hinged to the suction chamber;

[0023] The connecting rod is inserted into the connecting sleeve, and two adjacent connecting rods are connected by ball joints;

[0024] The first spring is placed between the connecting sleeve and the connecting rod.

[0025] When the suction assembly is opened, all the suction chambers are opened simultaneously through the connecting assembly, and adjacent suction chambers are connected through the structure between the connecting sleeve and the connecting rod. The position of the suction chamber in the working state causes the connecting rod to retract into the connecting sleeve through the action of the first spring, so that the connecting assembly occupies a smaller space. When the suction chamber is in the open state, the connecting rod extends from the connecting sleeve, and the two adjacent connecting rods are connected by ball joints to ensure stable rotation of the suction chamber.

[0026] Furthermore, the suction assembly is provided with a folding piece, and the folding piece is installed between two adjacent suction chambers.

[0027] Adjacent suction chambers are connected by folding parts, which prevent flying catkins from passing through the gaps between the suction chambers and ensure that the suction chambers can rotate stably. The folding parts are connected to the side walls of the suction chambers by welding or fasteners such as screws. The folding parts are made of flexible rubber, plastic, plastic and other materials.

[0028] Furthermore, the suction seat includes:

[0029] Top block, movably installed in the suction seat;

[0030] a second spring, disposed between the top block and the suction seat;

[0031] a pressure sensor, abutting against the second spring;

[0032] Wherein, the suction chamber is provided with an abutment portion corresponding to the top block.

[0033] An abutment portion is provided on the suction chamber where no tooth portion is provided. When the suction portion rotates, the abutment portion acts on the top block, controlling the second spring corresponding to the top block to be compressed first and then reset. When the driving device controls the corresponding suction chamber to be in a working or open stroke end position, it is ensured that all the suction chambers are at the end of the stroke. However, when the gear drive tooth portion rotates and is not at the stroke end, the position of the suction chamber is detected by the pressure sensor.

[0034] Furthermore, the suction chamber and the rotary connector are connected via a sealed bearing.

[0035] The sealed bearing ensures the sealing performance between the suction chamber and the rotating connection, ensuring that the suction chamber can stably absorb flying catkins.

[0036] The beneficial effects of this application are:

[0037] 1. The suction chamber is connected to the vacuum suction unit so that the suction port of the suction chamber generates suction to absorb and collect the fluff and other flying catkins floating in the air to ensure the environment in the working space.

[0038] 2. When the suction assembly needs to be opened for maintenance of the circular knitting machine body, the suction chamber is driven to rotate outward through the adjustment mechanism to improve the efficiency of opening the suction chamber and reduce labor intensity.

[0039] 3. When the suction component is opened, all the suction chambers are opened simultaneously through the connection component. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] The adjustment mechanism 400 is used to drive the suction chamber 210 to rotate, and the suction chamber 210 is provided with a suction port 211 .

[0058] Several suction chambers 210 are evenly distributed in a circle and hinged on the suction seat 300. The suction chambers 210 are connected to the vacuum suction unit so that the suction port 211 of the suction chamber 210 generates suction to absorb and collect the fluff and other flying catkins floating in the air, thereby improving the environment in the working space. When the suction assembly 200 needs to be opened for maintenance of the circular knitting machine body 100, the suction chamber 210 is driven to rotate outward through the adjustment mechanism 400 to improve the efficiency of opening the suction chamber 210 and reduce labor intensity. The rotating connector 500 is used to connect the suction chamber 210 and the vacuum suction unit. The rotating connector 500 is movably connected to the suction chamber 210 to ensure stable transmission of suction pressure when the suction chamber 210 rotates.

[0061] The teeth 410 are placed on a plurality of the suction chambers 210;

[0062] The gear 420 is mounted on the suction base 300 and corresponds to the tooth portion 410;

[0063] The driving device 430 is mounted on the suction base 300 and connected to the gear 420;

[0065] The suction seat 300 is provided with a limiting portion 450 corresponding to the tooth portion 410 .

[0066] The tooth portion 410 is placed on the suction chamber 210, and the axis of the tooth portion 410 is the same as the rotation axis of the suction chamber 210. The gear 420 is engaged with the tooth portion 410. When the driving device 430 drives the gear 420 to rotate, the suction chamber 210 is rotated. 2-4 suction chambers 210 on the suction assembly 200 are installed with the tooth portion 410, and all the suction chambers 210 are connected through the connecting assembly 440. When multiple driving devices 430 are driven at the same time, the suction chambers 210 on the suction assembly 200 are controlled to rotate and open at the same time, thereby further improving the opening efficiency of the suction chamber 210. The limiting portion 450 is used to limit the rotation stroke of the suction chamber 210 to control the position of the suction chamber 210 in the working and open states.

[0067] Furthermore, the connection component 440 includes:

[0068] The connecting sleeve 441 is hinged to the suction chamber 210;

[0069] The connecting rod 442 is inserted into the connecting sleeve 441, and two adjacent connecting rods 442 are connected by ball joints;

[0070] The first spring 443 is disposed between the connecting sleeve 441 and the connecting rod 442 .

[0071] When the suction assembly 200 is opened, all the suction chambers 210 are controlled to open at the same time through the connecting assembly 440, and the adjacent suction chambers 210 are connected through the structure between the connecting sleeve 441 and the connecting rod 442. The position of the suction chamber 210 in the working state causes the connecting rod 442 to retract into the connecting sleeve 441 through the action of the first spring 443, so that the connecting assembly 440 occupies a smaller space. When the suction chamber 210 is in the open state, the connecting rod 442 extends from the connecting sleeve 441, and the two adjacent connecting rods 442 are connected by ball joints to ensure the stable rotation of the suction chamber 210.

[0072] Furthermore, the suction assembly 200 is provided with a folding piece 220 , and the folding piece 220 is installed between two adjacent suction chambers 210 .

[0073] Adjacent suction chambers 210 are connected by folding parts 220, so that flying catkins are not easy to pass through the gaps between the suction chambers 210, and the suction chambers 210 can be rotated stably. The folding parts 220 are connected to the side walls of the suction chambers 210 by welding or fasteners such as screws. The folding parts 220 are made of flexible rubber, plastic, plastic and other materials.

When the suction portion rotates, the abutment portion 212 acts on the top block 310, controlling the second spring 320 corresponding to the top block 310 to be compressed first and then reset. When the driving device 430 controls the corresponding suction chamber 210 to be in a working or open stroke end position, it is ensured that all the suction chambers 210 are at the end of the stroke. However, when the gear 420 drives the tooth portion 410 to rotate and is not at the stroke end, the position of the suction chamber 210 is detected by the pressure sensor 330.

[0081] Furthermore, the suction chamber 210 and the rotary connector 500 are connected via a sealed bearing.
