A circular knitting machine with lint cleaning function

Abstract

The application provides a large circular knitting machine with lint cleaning function, comprising a large circular knitting machine body and a lint removing structure. The lint cleaning and knitting can be carried out simultaneously through the collaborative design of the lint removing structure and the large circular knitting machine body. During work, the motor drives the installation disc to drive the scraping plate in the dust scraping structure to continuously rotate around the needle disc for cleaning. The lint around the needle disc and the triangular block can also be removed by the spray head in the two groups of dust scraping structures and the external air pump. The above two working states can complete the lint removal without stopping the machine, avoid production interruption caused by cleaning, effectively improve the continuous production time and overall production efficiency of the equipment, and automatically complete the lint cleaning without frequent manual intervention. Only by adjusting the pipe setting angle and confirming the working state in the early stage can the continuous and stable cleaning be realized, which reduces the labor intensity and labor cost and improves the reliability of lint cleaning.

Description

Technical Field

[0001] This application relates to the field of circular knitting machine technology, and in particular to a circular knitting machine with a lint removal function. Background Technology

[0002] Circular knitting machines are core equipment in the knitting industry for mass production of cylindrical knitted fabrics (such as underwear fabrics, sweatshirt fabrics, home textile fabrics, etc.). With their high-speed operation and continuous knitting characteristics, they are widely used in the processing of various yarns such as cotton spinning, chemical fiber, and blended yarns. They are key equipment for achieving efficient production in the modern knitting industry chain.

[0003] The existing technology has the following problems: In actual production, lint is easily generated and accumulated at the connection between the needle plate and the triangular block, and at the top of the triangular block. Lint accumulation will seriously affect the fabric quality. Lint that is not cleaned in time will enter the needle groove or triangular block track with the movement of the knitting needle, resulting in increased resistance to needle lifting and lowering, inaccurate reset, and problems such as missed needles and wrong needles.

[0004] Currently, the main method for handling hair dander is manual cleaning by stopping the machine. This method requires stopping the machine for 15-30 minutes every 2-4 hours, and it also has the problems of incomplete cleaning and reduced production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a large circular knitting machine with lint removal function in order to solve the above-mentioned problems.

[0006] The technical solution of this application is implemented as follows:

[0007] This application provides a large circular knitting machine with lint removal function, including a large circular knitting machine body. The outer periphery of the needle plate of the large circular knitting machine body is provided with a lint removal structure. The lint removal structure includes a chassis, which is sleeved on the outside of the needle plate of the large circular knitting machine body. A rotating disk is coaxially embedded on the top end face of the chassis. An installation disk is rotatably mounted on the top of the rotating disk. The installation disk is rotatably mounted on the top of the chassis through the rotating disk and sleeved on the outside of the needle plate of the large circular knitting machine body. Driven teeth are arrayed on the outer edge of the installation disk. A drive gear is meshed on the outer side of the driven teeth. The bottom of the drive gear is rotatably mounted on the top of the chassis. Its top is also coaxially connected to the output end of a motor through a coupling. A dust suction and scraping structure is provided on the top of the installation disk.

[0008] In one embodiment, the vacuum scraping structure includes a base, which is fixedly installed on the top surface of the mounting plate. A rotating shaft is fixedly installed on the top of the base. A connecting seat is rotatably installed on one side of the rotating shaft via a bearing. A connecting pipe is provided through the connecting seat. One end of the connecting pipe is connected to an air pump, and the other end passes through the connecting seat and is connected to an adjusting pipe. A connector is provided at the front end of the adjusting pipe. A scraper is fixedly provided at the bottom of the connector, and a nozzle is fixedly sleeved at the air outlet end of the connector.

[0009] In one embodiment, the adjusting tube is a hollow tubular structure, and the adjusting tube is made of a bendable and shape-adjustable elastic material, which can be manually bent to achieve shape adjustment at any angle.

[0010] In one embodiment, the scraping end face of the scraper is inclined at a 15°-30° angle to the scraper body.

[0011] In one embodiment, the dust suction scraping structure is provided in no fewer than two sets.

[0012] In one embodiment, the chassis is a ring structure, and its bottom end face is fixedly connected to the fixed base of the large circular knitting machine body 1. The chassis is coaxially sleeved on the outside of the needle plate and the triangular block.

[0013] The advantages or beneficial effects of the above technical solutions include at least the following:

[0014] This application discloses a circular knitting machine with lint removal function. Through the coordinated design of the lint removal structure and the circular knitting machine body, lint removal and knitting can be carried out simultaneously. During operation, the motor drives the mounting plate to drive the scraper in the dust suction scraping structure to continuously rotate around the needle plate for cleaning. Alternatively, the nozzles in the two sets of dust suction scraping structures can be connected to an external air pump to achieve targeted removal of lint around the needle plate and triangular blocks.

[0015] Both of the above working states can complete the lint removal without stopping the machine, avoiding production interruptions caused by cleaning and effectively improving the continuous production time and overall production efficiency of the equipment;

[0016] Furthermore, the lint removal structure can automatically clean up lint. Only the initial adjustment of the tube's shaping angle and confirmation of the working status are needed to achieve continuous and stable cleaning, which reduces the intensity of manual operation and labor costs, and improves the reliability of lint cleaning.

[0029] Reference Figure 1 A circular knitting machine with lint removal function includes a circular knitting machine body 1. The circular knitting machine body 1 is used to undertake the knitting production function of knitted fabrics, which is existing known technology, so it will not be described in detail.

[0030] The outer periphery of the needle plate of the circular knitting machine body 1 is provided with a lint removal structure 2. The lint removal structure 2 is used to clean the lint, fuzz and other impurities generated around the needle plate during the knitting process, so as to reduce the interference of lint accumulation on the normal operation of the needle plate and ensure the stability of the knitting process.

[0031] In one embodiment, reference is made to Figures 2-4 The de-fluffing structure 2 includes a chassis 21, which is sleeved on the outside of the needle plate of the large circular knitting machine body 1. The chassis 21 is used for installation and connection, and provides a stable installation reference for components such as the rotating disc 22, the drive gear 25, and the motor 26. Its bottom end face is fixedly connected to the fixed base of the large circular knitting machine body 1 by bolts, and is sleeved on the outside of the needle plate of the large circular knitting machine body 1.

[0032] In one embodiment, the chassis 21 has a ring structure, and its bottom end face is fixedly connected to the fixed base of the large circular knitting machine body 1. The chassis 21 is coaxially sleeved on the outside of the needle plate and the triangular block.

[0033] The ring structure can adapt to the circumferential distribution of the needle plate and triangular blocks. When it is installed, it can avoid the rotating needle plate and avoid interfering with its knitting operation. At the same time, it provides a ring mounting reference for the rotating plate 22 and mounting plate 23 of the lint removal structure 2.

[0034] A rotating disk 22 is coaxially embedded on the top end face of the chassis 21. The rotating disk 22 has a ring structure, and its top is rotated with the bottom of the mounting disk 23 through a sliding bearing. Its function is to rotatably support the mounting disk 23 on the chassis 21, ensuring that the mounting disk 23 can rotate smoothly relative to the chassis 21.

[0035] A mounting plate 23 is rotatably mounted on the top of the rotating disk 22. The mounting plate 23 is rotatably mounted on the top of the chassis 21 via the rotating disk 22 and is sleeved on the outside of the needle plate of the large circular machine body 1. The mounting plate 23 is used to install the dust suction scraping structure 27, and it meshes with the drive gear 25 through the driven teeth 24 on the outer edge. Under the power drive, it rotates around the needle plate, driving the dust suction scraping structure 27 to expand the cleaning range.

[0036] The outer edge of the mounting disc 23 is provided with driven teeth 24, which are used to mesh with the drive gear 25 to convert the power transmitted by the drive gear 25 into the rotational motion of the mounting disc 23, thereby driving the dust suction scraping structure 27 to rotate around the needle disc and expand the cleaning range.

[0037] Drive gear 25 is meshed with the outer side of driven gear 24. The bottom of drive gear 25 is rotatably mounted on the top of chassis 21. Its top is also coaxially connected to the output end of motor 26 via a coupling. The bottom of drive gear 25 is rotatably mounted on the top of chassis 21 via bearing. Drive gear 25 is used to transmit the power of motor 26 to driven gear 24 of mounting plate 23, driving mounting plate 23 to rotate.

[0038] The top of the mounting plate 23 is equipped with a dust-scraping structure 27, which can rotate synchronously with the mounting plate 23 to scrape off lint and perform targeted adsorption.

[0039] In one embodiment, reference is made to Figure 5 The vacuum scraping structure 27 includes a base 271, which is fixedly installed on the top surface of the mounting plate 23. The base 271 is used for installation and connection, and its bottom is detachably fixed to the top surface of the mounting plate 23 by bolts.

[0040] A rotating shaft 272 is fixedly installed at the top of the base 271. The rotating shaft 272 is vertically fixed to the top of the base 271 by welding. It cooperates with the connecting seat 273 through a bearing to provide rotational support for the connecting seat 273, so that the connecting seat 273 can rotate around the rotating shaft 272, thereby adjusting the cleaning angle of the scraper 277 and the fixed nozzle 278.

[0041] A connecting seat 273 is rotatably mounted on one side of the rotating shaft 272 via a bearing. The connecting seat 273 is used to install the connecting pipe 274, and by rotating around the rotating shaft 272, it drives the scraper 277 and the nozzle 278 to adjust their spatial positions to match the gap between the needle plate and the triangular block.

[0042] A connecting pipe 274 is provided through the connecting seat 273. One end of the connecting pipe 274 is connected to an air pump. In this embodiment, the connecting pipe 274 is made of rigid pipe, such as PVC pipe or metal pipe. The connecting pipe 274 is used to form an airflow channel between the air pump and the regulating pipe 275, providing an airflow transmission path for lint adsorption or airflow jetting.

[0043] The other end of the connecting pipe 274 passes through the connecting seat 273 and is connected to an adjusting pipe 275. The adjusting pipe 275 is used to allow the user to adjust the spatial posture of the scraper 277 and the nozzle 278, so as to clean up the hair more efficiently.

[0044] The front end of the regulating pipe 275 is connected to a connector 276, which is used for installation and connection.

[0045] A scraper 277 is fixedly provided at the bottom of the connector 276. The scraper 277 adopts a corresponding fixing method according to the material of the connector 276. For example, it is integrally injection molded with the plastic connector 276, and fixed with the metal connector 276 by laser welding.

[0046] The scraper 277 is used to rotate with the mounting plate 23 and adjust the angle of the tube 275 to physically scrape away the lint accumulated in the gap between the needle plate and the triangular block, and at the top of the triangular block.

[0047] Furthermore, the air outlet end of the connector 276 is fixedly fitted with a nozzle 278. The nozzle 278 is used to concentrate the negative pressure airflow or high pressure airflow transmitted by the connecting pipe 274 to the scraping area of ​​the scraper 277, quickly adsorb the scraped hair, and prevent the hair from falling again or accumulating in the gap between the blowing needle plate and the triangular block, or at the top of the triangular block.

[0048] In one embodiment, the regulating pipe 275 is a hollow tubular structure. The regulating pipe 275 is hollow tubular and can serve as an airflow channel to connect the connecting pipe 274 and the connector 276 to realize airflow transmission.

[0049] Furthermore, the regulating tube 275 is made of a flexible material that can be bent and shaped. One end is connected to the protruding end of the connecting tube 274 through a sealing sleeve and fastened with a hose clamp, while the other end is sealed and connected to the connector 276. In this embodiment, the regulating tube 275 is made of a metal corrugated tube, which can be manually bent to achieve shaping and adjustment at any angle. It can flexibly adapt to the complex gap between the needle plate and the triangular block, ensuring that the scraper 277 and the nozzle 278 are accurately aligned for efficient cleaning.

[0050] In one embodiment, the scraping end face of the scraper 277 is inclined at a 15° angle to the scraper body. The 15° angle design can conform to the connection gap contour of the needle plate and the triangular block, increase the contact area between the scraping end face and the hair accumulation area, and improve the thoroughness of hair scraping.

[0051] At the same time, it reduces the direct impact on the surface of the needle plate and triangular block during scraping, and avoids scratching precision parts;

[0052] Furthermore, the 15° tilt angle design guides the scraped hairs to slide towards the nozzle 278, making it easier for the nozzle 278 to simultaneously absorb the hairs, preventing the hairs from falling back into the gaps or inside the machine, and ensuring cleaning efficiency.

[0053] In one embodiment, the vacuum scraping structure 27 is provided in two sets, which work together. One set physically scrapes away the lint from the gap between the needle plates using the scraper 277, while the nozzle 278 sprays high-pressure airflow to break up the stubborn lint and blow out the lint remaining in the gap.

[0054] The other group uses nozzle 278 to create negative pressure suction, simultaneously and quickly sucking away the lint scraped and broken up by the first group, preventing the lint from scattering again and greatly improving the efficiency and thoroughness of lint cleaning.

[0055] Working principle:

[0056] The main body 1 of the circular knitting machine is responsible for the knitting production of the fabric, while the lint removal structure 2 simultaneously cleans up lint around the outer periphery of the needle plate.

[0057] Specifically, there are two working states:

[0058] Point cleaning state: At this time, the nozzle 278 is connected to the external air pump pipeline, and the mounting plate 23 is kept fixed to avoid pipe entanglement. The two sets of nozzles 278 spray high-pressure airflow and generate negative pressure respectively. The nozzle 278 that sprays high-pressure airflow can break up the stubborn hair scraped off by the scraper 277 and blow out the hair residue in the gap of the needle plate, while the nozzle 278 that generates negative pressure is used to quickly suck away hair and surrounding impurities.

[0059] The scraper 277 works in conjunction with the rotating needle disc of the circular knitting machine to scrape off lint from the surface of the needle disc. A precisely controlled micro-gap is provided between the scraper 277 and the needle disc. This gap can effectively prevent the scraper 277 from scratching the needle tips and abrading the needle track on the needle disc, avoiding quality defects such as skipped stitches and missing stitches in the fabric due to needle deformation and needle jamming. At the same time, the 15° tilt angle design of the scraper 277 can guide the scraped needle disc lint to slide down towards the nozzle 278, ensuring cleaning efficiency.

[0060] If it is necessary to fine-tune the position of the nozzle 278 when connecting the nozzle 278 pipeline, the motor 26 can be controlled to drive the installation plate to rotate at low speed. At the same time, the pipeline can be manually combed in real time to avoid tangling. After adjustment, the fixed state can be restored and the operation can continue.

[0061] Rotary scraping state: At this time, no external air pump pipeline is required. After the motor 26 starts, it drives the drive gear 25 to rotate through the coupling. The drive gear 25 meshes with the driven gear 24 on the outer edge of the mounting plate 23, causing the mounting plate 23 to rotate smoothly around the needle plate with the help of the rotating plate 22. The dust suction scraping structure 27 rotates synchronously with the mounting plate 23. During the rotation, the scraper 277 thoroughly scrapes away the hair around the needle plate and the triangular block. In this working state, the scraper 277 should also have a precisely controlled small gap between it and the needle plate.
