A dustproof transmission structure for large circular knitting machines

Abstract

This application provides a dustproof transmission structure for a large circular knitting machine, including a large circular knitting machine body, a cabinet, a cabinet door, a vent, and a dustproof structure. This utility model forms a complete airflow channel through the air inlet on the side plate and the vent on the top of the cabinet, ensuring that cold air from the outside can smoothly enter the cabinet and carry away the heat of the transmission components to ensure heat dissipation efficiency. At the same time, the dustproof cover partially surrounds and protects against large particles of impurities, while the filter screen filters out fine impurities, achieving the dual effect of dust prevention and heat dissipation without disrupting airflow circulation. Addressing the problem of cumbersome cleaning in existing systems, workers only need to hold the handle and push the scraping structure. The slider slides along the slide rail, causing the scraper to adhere to the inside of the dustproof cover and the surface of the filter screen to scrape away impurities. The first telescopic structure and the second telescopic structure also provide left and right fine adjustment margins to reach the bottom corners of the dustproof cover for cleaning. Cleaning can be completed without disassembling parts, significantly reducing the workload of workers.

Description

Technical Field

[0001] This application relates to the field of large circular knitting machine technology, and in particular to a dustproof transmission structure for large circular knitting machines. Background Technology

[0002] During the operation of a circular knitting machine, the stability of its transmission system directly affects the quality and production efficiency of knitted products. Currently, the transmission system of a circular knitting machine is mainly divided into two types: semi-open and closed. Among them, the closed transmission structure is widely used in the field of knitting production because it can effectively isolate impurities such as flying fluff and dust from the external environment from entering the transmission mechanism. However, while the enclosed structure achieves a good sealing effect, it also makes it difficult to effectively dissipate the heat generated by the motor and gear meshing during the operation of the transmission system. To solve this heat dissipation problem, the existing technology often adopts the method of adding a cooling fan inside the transmission structure cabinet, and the fan drives the airflow to remove the heat. The existing technology has the following problems: In order to achieve airflow circulation, it is usually necessary to open air inlets on the side of the cabinet so that outside air can enter the cabinet and exchange heat before being exhausted by the fan. Since the fan will create negative pressure inside the cabinet when it runs, flying fluff and dust in the outside environment will be continuously attracted to the side air inlets under the airflow. After long-term use, they are very easy to accumulate in the hole walls and gaps, causing blockage, which prevents outside air from entering the cabinet smoothly. If not cleaned in time, some fine dust and flying fluff will also penetrate the gaps and enter the cabinet under the continuous action of airflow, affecting the stable operation of the transmission structure. The cleaning process for the workers is tedious and difficult, which greatly increases their workload. Utility Model Content

[0003] The purpose of this utility model is to provide a dustproof transmission structure for large circular knitting machines in order to solve the above-mentioned problems.

[0004] The technical solution of this application is implemented as follows: This application provides a dustproof transmission structure for a large circular knitting machine, including a large circular knitting machine body. A cabinet is fixedly installed on the outside of the machine body frame. The cabinet has an openable door and a ventilation port on the top. It also includes a dustproof structure embedded in either the left or right side of the cabinet. The dustproof structure includes a side panel embedded in either the left or right side of the cabinet. Several air inlets are arrayed on the side of the side panel away from the cabinet. The cabinet is connected to the outside through these air inlets. A dust cover is fixedly connected to the side panel away from the cabinet, forming a semi-enclosed area around the air inlets. The side panel away from the cabinet has symmetrical slide rails on both ends. A slider is slidably installed on the slide rail. An accordion-style protective sleeve is fitted on the slide rail. One end of the accordion-style protective sleeve is fixedly connected to the end of the slider, and the other end is fixedly connected to the end of the slide rail. A buckle is fixedly installed on the side panel away from the cabinet near the end of the slide rail. A scraping structure is fixedly connected to the left mounting surface of the slider. The scraping structure can move back and forth up and down along the height direction of the side panel corresponding to the dust cover through the sliding cooperation between the slider and the slide rail. After the scraping structure slides to the opening of the buckle, it can fit into the buckle to achieve positioning.

[0005] In one embodiment, the scraping structure includes a first connecting rod and a second connecting rod. The bottom of the first connecting rod has several sets of reinforcing ribs arranged in an array along its length direction, and is fixedly connected to the second connecting rod through the reinforcing ribs. A handle is fixedly installed on the left side of the reinforcing ribs. The bottom of the second connecting rod has several scraping plates arranged in an array along its length direction, which are adapted to the position of the dust cover. The left and right ends of the first and second connecting rods along their length directions are respectively fixedly connected to a first telescopic structure and a second telescopic structure. The right side of the first and second telescopic structures is fixedly installed on the left mounting surface of the slider by bolts, and through the sliding cooperation between the slider and the slide rail, the first connecting rod, the second connecting rod, and the scraping plates can be synchronously driven to reciprocate up and down along the height direction of the side plate corresponding to the dust cover.

[0006] In one embodiment, the first connecting rod and the second connecting rod are of equal length, and their ends are aligned along the length direction and arranged parallel to each other along the axial direction.

[0007] In one embodiment, the first telescopic structure and the second telescopic structure are the same structure; The first telescopic structure includes a first mounting plate and a second mounting plate. A top plate is fixedly installed at the top between the two, and a bottom plate is integrally formed at the bottom between the two. The first mounting plate and the second mounting plate are fixedly installed on the left mounting surface of the slider by bolts on the side facing the slider. A first outer cylinder and a second outer cylinder are symmetrically fixedly installed between the first mounting plate and the second mounting plate in the vertical direction. Both are provided with springs. The left ends of the first connecting rod and the second connecting rod pass horizontally through the first mounting plate and then pass through the cylinder walls of the first outer cylinder and the second outer cylinder respectively and extend into their interiors. They are fixedly connected to one end of the spring inside the first outer cylinder and the second outer cylinder respectively. The other end of the spring is fixedly connected to the inner bottom of the corresponding outer cylinder. The first mounting plate and the second mounting plate can slide together with the slider and the slide rail, and synchronously drive the first telescopic structure and the first connecting rod and the second connecting rod connected thereto to move back and forth up and down along the dust cover corresponding to the height direction of the side plate.

[0008] In one embodiment, the scraper includes a support rod, the top end of which is fixedly installed at the bottom of a second connecting rod. A crossbar is integrally formed on the bottom of the support rod facing the side plate. A connecting rod is fixedly installed on the bottom of the crossbar facing the side plate. A scraper is fixedly installed on the bottom of the connecting rod. The scraping surface of the scraper is in close contact with the inside of the dust cover.

[0009] In one embodiment, a scraper blade is integrally formed and extends downward from the bottom of the scraping surface of the scraper. The extension direction of the scraper blade is adapted to the scraping direction of the scraper blade and can move synchronously with the scraper blade to scrape away impurities accumulated at the bottom inside the dust cover.

[0010] In one embodiment, a filter screen is fitted into the opening of the dust cover, and the filter screen is in close contact with the scraping surface of the scraper.

[0011] In one embodiment, the scraping surface of the scraper is made of nylon, and the filter screen is made of polypropylene. When the scraping surface of the scraper rubs against the surface of the filter screen, a weak static electricity is generated, which can adsorb the lint and dust remaining on the surface of the filter screen.

[0012] The advantages or beneficial effects of the above technical solutions include at least the following: This application discloses a dustproof transmission structure for a large circular machine. The air inlet on the side plate and the air vent on the top of the cabinet form a complete airflow channel, ensuring that cold air from the outside can smoothly enter the cabinet and carry away the heat of the transmission components to ensure heat dissipation efficiency. At the same time, the dust cover partially surrounds and protects against large particles of impurities, and the filter screen filters out fine impurities, achieving the dual effect of dustproof and heat dissipation without disrupting the airflow circulation. Furthermore, the dust cover reduces the direct contact of impurities with the air inlet, and the filter screen, together with the scraper, generates weak static electricity through friction with the filter screen to adsorb residual fine impurities, greatly reducing the probability of air inlet hole wall accumulation and blockage and fine impurities penetrating the gaps and entering the cabinet. To address the cumbersome cleaning process of existing systems, workers only need to hold the handle and push the scraping mechanism. The slider moves along the slide rail, causing the scraper to adhere to the inside of the dust cover and the surface of the filter screen to remove impurities. The first and second telescopic structures also provide fine-tuning allowance to reach the bottom corners of the dust cover for cleaning. Cleaning can be completed without disassembling any parts, significantly reducing the workload of workers. Attached Figure Description

[0021] Reference Figure 1 A dustproof transmission structure for a large circular knitting machine includes a large circular knitting machine body 1 and a dustproof structure 5. The large circular knitting machine body 1 is used for installation, connection, weaving, and other work, which is existing known technology and will not be described in detail. A cabinet 2 is fixedly installed on the outside of the frame of the large circular knitting machine 1. The cabinet 2 is used to provide physical protection for the internal transmission components, preventing the transmission components from being directly exposed to the outside and subjected to external collisions and wear, while providing a relatively enclosed installation and operating space for the transmission components. The cabinet 2 has an opening door 3 that can be opened and closed. The cabinet door 3 is used to close the opening of the cabinet 2, enhance the protection of the cabinet 2, and the opening and closing design makes it convenient for staff to open the cabinet 2 to inspect, maintain or debug the internal transmission components. Furthermore, a ventilation port 4 is provided through the top of the cabinet 2. The ventilation port 4 is used to allow air circulation between the inside of the cabinet 2 and the outside, which helps the transmission components inside the cabinet 2 to dissipate heat.

[0022] In one embodiment, reference is made to Figures 2-3The dustproof structure 5 is embedded on either the left or right side of the cabinet 2. The dustproof structure 5 is used to block dust, fluff and other impurities in the external environment from entering the interior through the air intake area of ​​the cabinet 2, so as to avoid impurities adhering to the transmission components and affecting their transmission accuracy and service life, and to ensure that the transmission structure inside the cabinet 2 is always in a relatively clean operating environment.

[0023] The dustproof structure 5 includes a side panel 51, which is embedded in either the left or right side of the cabinet 2. In this embodiment, the side panel 51 is embedded in the left side of the cabinet 2. The side panel 51 is used for installation and connection, and at the same time, it separates the inner and outer spaces of the cabinet 2 through its own structure, forming a dual effect of dustproof and air intake.

[0024] The side panel 51, away from the cabinet 2, has several air inlets 52 arranged in an array. The cabinet 2 is connected to the outside world through the air inlets 52. The air inlets 52 are the channels for air exchange between the cabinet and the outside world, providing the necessary cold air from the outside for heat dissipation of the internal transmission components of the cabinet 2 and ensuring airflow circulation. In this embodiment, eight air inlets 52 are provided. The presence of eight inlets can significantly improve air intake efficiency, ensuring that the fans inside the cabinet 2 can draw in enough cool outside air and improve heat dissipation efficiency.

[0025] A dust cover 53 is fixedly connected to the side panel 51 away from the cabinet 2 in a semi-enclosed manner to the overall opening area of ​​the air inlet 52. The number of dust covers 53 corresponds to the number of air inlets 52. The dust covers 53 are used to protect the air inlets 52, which can initially block large particles of flying fluff and dust from directly contacting the air inlets 52. At the same time, it provides space for the scraping structure 58 to work, reducing the probability of impurities directly adhering to the air inlets 52.

[0026] The side panel 51 is symmetrically provided with slide rails 54 on the left and right ends of the side away from the cabinet 2. The slide rails 54 serve as motion guides for the slider 55, limiting the sliding trajectory of the slider 55 and ensuring that the scraping structure 58 moves smoothly along the height direction of the side panel 51. A slider 55 is slidably mounted on the slide rail 54. The slider 55 is used to transmit its sliding motion along the slide rail 54 to the scraping structure 58, thereby driving the scraping structure 58 to perform up and down scraping action. An accordion-style protective sleeve 56 is fitted on the slide rail 54. One end of the accordion-style protective sleeve 56 is fixedly connected to the end of the slider 55, and the other end is fixedly connected to the end of the slide rail 54. It can extend and retract with the movement of the slider 55, which can isolate external dust and flying lint from entering the gap between the slide rail 54 and the slider 55, prevent the slide rail 54 from being contaminated and causing it to slide and jam, and protect the smooth operation of the slide rail 54.

[0027] A buckle 57 is fixedly installed on the side panel 51 away from the cabinet 2 near the end of the slide rail 54. The buckle 57 is used to position and fix the scraping structure 58 by embedding and engaging when the scraping structure 58 is not working, so as to prevent the scraping structure 58 from shaking randomly and affecting the operation of the equipment.

[0028] A scraping structure 58 is fixedly connected to the left mounting surface of the slider 55. The scraping structure 58 can move up and down along the height direction of the side plate 51 corresponding to the dust cover 53 through the sliding cooperation between the slider 55 and the slide rail 54. After the scraping structure 58 slides to the opening of the buckle 57, it can be fitted into the buckle 57 to achieve positioning. The scraping structure 58 moves back and forth along the dust cover 53 to scrape away impurities such as lint and dust attached to the dust cover 53, keeping the dust cover clean and ensuring the ventilation efficiency of the air inlet 52.

[0029] In one embodiment, reference is made to Figures 4-5 The scraping structure 58 includes a first connecting rod 581 and a second connecting rod 582. The bottom of the first connecting rod 581 is provided with a number of reinforcing ribs 583 arranged in an array along its length direction, and is fixedly connected to the second connecting rod 582 through the reinforcing ribs 583. The first connecting rod 581 and the second connecting rod 582 form an integral structure through the reinforcing rib 583, which is used for installation and transmission of motion trajectory; In this embodiment, five sets of reinforcing ribs 583 are provided. The five sets of reinforcing ribs 583 can enhance the connection strength and overall structural rigidity of the two, prevent deformation under stress, and provide a fixed carrier for the handle 584.

[0030] A handle 584 is fixedly installed on the left side of the reinforcing rib 583. The handle 584 serves as the operating force point, making it convenient for the operator to hold and push the entire scraping structure 58. The scraping structure 58 is driven by human power to slide up and down with the slider 55.

[0031] The bottom of the second connecting rod 582 is arranged with several scraping plates 585 that are adapted to the position of the dust cover 53 along its length. The number of scraping plates 585 corresponds to the number of dust covers 53. The scraping plates 585 can be adjusted left and right and slid up and down with the second connecting rod 582. They can scrape off surface impurities along the inner side of the dust cover 53, and can also reach into the bottom area of ​​the dust cover 53 through small left and right flexible displacement to completely scrape out the accumulated flying lint, so as to avoid impurities remaining and blocking the air intake channel.

[0032] The first connecting rod 581 and the second connecting rod 582 are respectively fixedly connected to the left and right ends of their length direction by the first telescopic structure 586 and the second telescopic structure 587. The right side of the first telescopic structure 586 and the second telescopic structure 587 are fixedly installed on the left side mounting surface of the slider 55 by bolts. Through the sliding cooperation between the slider 55 and the slide rail 54, the first connecting rod 581, the second connecting rod 582 and the scraper plate 585 are synchronously driven to move up and down along the height direction of the side plate 51 corresponding to the dust cover 53. The first telescopic structure 586 and the second telescopic structure 587 serve as connecting bridges between the slider 55 and the first connecting rod 581 and the second connecting rod 582, transmitting the up-and-down sliding power of the slider 55 along the slide rail 54 to the first connecting rod 581 and the second connecting rod 582, thereby driving the scraper plate 585 to scrape up and down synchronously. It can also provide a small range of left and right extension, allowing the first connecting rod 581 and the second connecting rod 582 to slide slightly left and right, thereby driving the scraper plate 585 to scrape the corners or gaps at the bottom of the dust cover 53, avoiding cleaning dead corners caused by fixed position, and scraping the flying lint accumulated at the bottom of the dust cover 53 out of the cover.

[0033] The first connecting rod 581 and the second connecting rod 582 are of equal length, and their ends are aligned along the length direction and their axes are parallel. This structural design can form a symmetrical and uniform frame structure, and after being connected with the reinforcing rib 583, it can avoid local stress concentration and deformation. It can also ensure that the two move in parallel and synchronously without jamming when they are finely adjusted with the first telescopic structure 586 and the second telescopic structure 587 or when they slide with the slider 55. It can also make the scraper plate 585 at the bottom of the second connecting rod 582 evenly distributed and have a consistent scraping path, avoiding cleaning dead corners and ensuring a stable cleaning effect on the inside of the dust cover 53.

[0034] In one embodiment, reference is made to Figures 6-7 The first telescopic structure 586 and the second telescopic structure 587 are the same structure. This structure design can ensure that the support force and limiting accuracy of the two on the first connecting rod 581 and the second connecting rod 582 are consistent, ensuring that the scraping structure 58 moves synchronously and is subjected to balanced force when sliding up and down. At the same time, it can realize the commonality of parts to simplify design and production, and also reduce assembly difficulty and later maintenance costs. The first telescopic structure 586 includes a first mounting plate 5861 and a second mounting plate 5862. A top plate 5863 is fixedly disposed at the top between the two, and a bottom plate 5864 is integrally formed at the bottom between the two. The first mounting plate 5861 and the second mounting plate 5862 are fixedly mounted on the left mounting surface of the slider 55 by bolts on the side facing the slider 55. The first mounting plate 5861 and the second mounting plate 5862 serve as the basic frame of the first telescopic structure 586, mainly used for installation and connection, while transmitting the movement of the slider 55 to the entire telescopic structure. The top plate 5863 and the bottom plate 5864 are used to enhance the connection rigidity between the first mounting plate 5861 and the second mounting plate 5862, prevent them from deforming under stress, and ensure the stability of the installation.

[0035] A first outer cylinder 5865 and a second outer cylinder 5866 are symmetrically fixed between the first mounting plate 5861 and the second mounting plate 5862 in the vertical direction. The first outer cylinder 5865 and the second outer cylinder 5866 serve as mounting cavities for the spring 5867 and movement guides for the first connecting rod 581 and the second connecting rod 582, restricting the spring 5867, the first connecting rod 581 and the second connecting rod 582 to extend and retract only in the horizontal direction, thus preventing deviation.

[0036] Both are equipped with a spring 5867 inside the outer cylinder. One end is connected to the connecting rod and the other end is fixed to the bottom of the outer cylinder. The spring provides buffering and restoring force through its own elastic deformation, allowing the first connecting rod 581 and the second connecting rod 582 to slide slightly left and right, driving the scraper plate 585 to clean the dead corners of the dust cover 53, and at the same time scraping the flying fluff accumulated at the bottom of the dust cover 53 out of the cover.

[0037] The left ends of the first connecting rod 581 and the second connecting rod 582 pass horizontally through the first mounting plate 5861, respectively, and then pass through the cylinder walls of the first outer cylinder 5865 and the second outer cylinder 5866 and extend into their interiors. They are fixedly connected to one end of the spring 5867 inside the first outer cylinder 5865 and the second outer cylinder 5866, respectively. The other end of the spring 5867 is fixedly connected to the inner bottom of the corresponding outer cylinder. The first connecting rod 581 and the second connecting rod 582 form a rigid limiting constraint through the first mounting plate 5861, the second mounting plate 5862, the first outer cylinder 5865, and the second outer cylinder 5866. Their lateral displacement is strictly limited, and lateral movement can only occur when a preset external force is applied to perform a push-pull operation.

[0038] The first mounting plate 5861 and the second mounting plate 5862 can move up and down synchronously along the dust cover 53 corresponding to the height direction of the side plate 51 as the slider 55 slides and engages with the slide rail 54.

[0039] In one embodiment, reference is made to Figure 8The scraper 585 includes a support rod 5851. The top end of the support rod 5851 is fixedly installed at the bottom of the second connecting rod 582. A crossbar 5852 is integrally formed on the bottom of the support rod 5851 facing the side plate 51. A connecting rod 5853 is fixedly installed on the bottom of the crossbar 5852 facing the side plate 51. The support rod 5851, the crossbar 5852 and the connecting rod 5853 serve as connecting carriers to transmit the movement trajectory of the second connecting rod 582 and ensure that the installation position of the scraper 5854 corresponds to the inside of the dust cover 53.

[0040] A scraper 5854 is fixedly installed at the bottom of the connecting rod 5853. The scraping surface of the scraper 5854 is in close contact with the inside of the dust cover 53. When the scraper 5854 slides up and down with the overall structure, it can scrape off the flying fluff, dust and other impurities attached to the inside of the dust cover 53.

[0041] In one embodiment, reference is made to Figure 9 The scraper 5854 has a scraper blade 5855 integrally formed at the bottom of the scraping surface and extends downward. The extension direction of the scraper blade 5855 is adapted to the scraping direction of the scraper 5854 and can move synchronously with the scraper 5854 to scrape away the impurities accumulated at the bottom inside the dust cover 53.

[0042] In one embodiment, reference is made to Figures 10-11 A filter screen 531 is fitted into the opening of the dust cover 53. The filter screen 531 is in close contact with the scraping surface of the scraper 5854. The filter screen 531 is used to block external flying fluff, dust and other impurities from entering the equipment through the opening of the dust cover 53, so as to avoid contamination of internal components. By sliding the scraping surface of the scraper 5854 up and down, impurities attached to the filter screen 531 can be scraped off, preventing the filter screen 531 from becoming clogged and ensuring its continuous permeability. At the same time, cleaning can be completed without disassembling the filter screen 531, taking into account dust prevention, continuous filtration and convenient maintenance.

[0043] The scraping surface of the scraper 5854 is made of nylon, and the filter screen 531 is made of polypropylene. When the scraping surface of the scraper 5854 rubs against the surface of the filter screen 531, a weak static electricity is generated. This static electricity can adsorb the lint and dust remaining on the surface of the filter screen 531.

[0044] At the same time, it should be noted that the side panel 51 and the dust cover 53 must be made of insulating material to block the electrostatic conduction path and prevent electrostatics from spreading to the internal equipment of the cabinet 2. This ensures the adsorption effect of electrostatics on impurities and prevents electrostatic interference or damage to the components inside the cabinet 2.

[0045] Working principle: When the transmission structure of the main body 1 of the large circular machine is running, the cabinet 2 first closes the opening through the cabinet door 3 to protect the internal transmission components from collision and wear. At the same time, the air vent 4 on the top of the cabinet 2 and the air inlet 52 on the side plate 51 form an airflow channel. Outside cold air enters the cabinet 2 through the air inlet 52, carries away the heat of the transmission components, and is discharged from the air vent 4 to achieve heat dissipation. The dust cover 53 of the side panel 51 corresponding to the air inlet 52 initially blocks large particles of impurities, and the filter 531 at the opening of the dust cover 53 further filters fine impurities to prevent impurities from entering the cabinet 2 and affecting the accuracy and life of the transmission components. When impurities adhere to the dust cover 53 or filter screen 531, the operator holds the handle 584 to push the scraping structure 58. The slider 55 slides up and down along the slide rail 54 with the push force and drives the scraping structure 58 to move synchronously. The scraping plate 585 fits against the inner side of the dust cover 53 and the surface of the filter screen 531 to scrape away impurities. The first telescopic structure 586 and the second telescopic structure 587 can also provide left and right fine adjustment margins to allow the scraping plate 585 to penetrate into the bottom corners of the dust cover 53 to remove accumulated fluff. At the same time, it scrapes the fluff accumulated at the bottom of the dust cover 53 out of the cover. When the scraping structure 58 is not working, it can be embedded in the buckle 57 to fix it to prevent shaking. During the sliding of slider 55, the accordion-style protective sleeve 56 extends and retracts to prevent dust from entering the slide rail 54 and slider 55, thus avoiding jamming. The first connecting rod 581 and the second connecting rod 582 are of equal length, aligned at both ends and parallel in axis, and are reinforced by the reinforcing rib 583 to enhance rigidity, ensuring that the scraping structure 58 moves synchronously without jamming and that the scraping path of the scraping plate 585 is consistent. Meanwhile, the weak static electricity generated by the friction between the scraper 5854 of the scraper 585 and the filter 531 can adsorb the fine impurities remaining on the filter 531 to increase the cleaning effect, while the insulating material of the side plate 51 and the dust cover 53 can block the conduction of static electricity to the transmission components inside the cabinet 2, avoiding static interference or damage to the components.
