Description

Technical Field

[0001] This utility model is a multi-station tensioning structure for circular knitting fabric production, belonging to the field of circular knitting fabric production equipment. Background Technology

[0002] The multi-station tensioning structure for circular knitting fabric production is an equipment component applied in the circular knitting fabric production process. It is designed to ensure that the fabric maintains the appropriate tension during production and to clean up the generated lint, thereby improving production quality and efficiency.

[0003] In the current circular knitting fabric production process, a large amount of lint is generated. When the existing tensioning structure conveys the knitted fabric and adjusts the tension, the lint easily adheres to the tension roller and re-contaminates the fabric as the tension roller rotates. Even though some equipment is equipped with a negative pressure adsorption cleaning device, some lint still adheres to the roller surface of the tension roller due to static electricity, reducing the lint collection efficiency, affecting the fabric processing quality, and increasing the fabric defect rate.

[0004] In summary, this utility model provides a multi-station tensioning structure for circular knitting fabric production to solve the above-mentioned problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-station tensioning structure for circular knitting fabric production, so as to solve the problem mentioned in the background technology that the lint adsorbed on the surface of the tensioning roller due to static electricity is not easy to clean, which leads to an increase in the defect rate of the fabric.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station tensioning structure for circular knitting fabric production, comprising a base plate and two tensioning rollers. Support columns are fixedly installed around the top of the base plate, and a load-bearing plate is fixedly installed between the tops of the four support columns. Two electric lifting rods are fixedly installed on both sides of the bottom of the load-bearing plate. A mounting frame is fixedly installed between the output ends of every two electric lifting rods. An electric rotating shaft is installed between the bottom of the inner walls of the two mounting frames. The two tensioning rollers are rotatably mounted between the inner walls of the mounting frames via the two electric rotating shafts. Connecting plates are fixedly installed on both sides of the bottom of the two mounting frames. A fixing plate is fixedly installed between the bottoms of every two adjacent connecting plates. A lint cleaning component penetrates the bottom of the fixing plate, which is located at the bottom of the tensioning roller surface.

[0007] Furthermore, the lint removal assembly includes a dust collection box and a suction seat. The dust collection box is fixedly installed at the bottom of the fixed plate, and the suction seat is fixedly installed at the top of the fixed plate. A suction groove is formed on the top of the suction seat and directly below the tension roller. A silicone scraper is fixedly installed on one side of the top of the suction seat and at the bottom of the tension roller surface. An air pump is fixedly installed on one side of the dust collection box. An air extraction pipe is connected between the air inlet of the air pump and one side of the dust collection box. An air outlet pipe is connected to the air outlet of the air pump. A filter plate is horizontally embedded inside the dust collection box and above the air extraction pipe. Multiple conveying pipes are evenly connected from front to back at the bottom of the suction groove. The bottom end of the conveying pipe passes through the suction seat, the fixed plate, and the dust collection box in sequence and extends into the interior of the dust collection box.

[0008] Furthermore, the bottom of the main cross-section of the dust collection trough is inverted bucket shape, and the dust collection trough is connected to the dust collection box through multiple conveying pipes, and the conveying pipes are fixedly connected to the dust collection base.

[0009] Furthermore, the conveying pipe is fixedly connected to the fixed plate, and the conveying pipe is fixedly connected to the dust collection box.

[0010] Furthermore, the main cross-section of the silicone scraper is triangular, and the top of the silicone scraper is in contact with the roller surface of the tensioning roller.

[0011] Furthermore, the front of the dust collection box is fixed with a door by screws, and both sides of the inner wall of the dust collection box are provided with slots for fitting the filter plate.

[0012] Furthermore, the slots on both sides of the inner wall of the dust collection box are open at the end near the box door, and rubber strips are fixedly embedded in the slots on both sides of the inner wall of the dust collection box.

[0013] The beneficial effects of this utility model are:

[0014] By installing a lint removal component below the tension roller surface, the silicone scraper of the lint removal component contacts the tension roller surface and effectively scrapes off lint when the tension roller rotates. Combined with the inverted bucket-shaped dust collection trough, the lint collection efficiency is greatly improved. The negative pressure generated by the air pump allows the lint to smoothly enter the dust collection box through the conveying pipe. The entire process prevents lint leakage and avoids it from adhering to the fabric again, effectively ensuring the quality of the fabric and reducing the defect rate caused by lint problems.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a multi-station tensioning structure for circular knitting fabric production, including a base plate 1 and two tensioning rollers 7. Support columns 2 are fixedly installed around the top of the base plate 1. A load-bearing plate 3 is fixedly installed between the tops of the four support columns 2. Two electric lifting rods 4 are fixedly installed on both sides of the bottom of the load-bearing plate 3. A mounting frame 5 is fixedly installed between the output ends of every two electric lifting rods 4. An electric rotating shaft 6 is installed between the bottom sides of the inner walls of the two mounting frames 5. The two tensioning rollers 7 are rotatably mounted between the inner walls of the mounting frames 5 via the electric rotating shafts 6. Connecting plates 8 are fixedly installed on both sides of the bottom of the two mounting frames 5. The electric lifting rods 4 are key components for adjusting the height of the tensioning rollers 7, and can adjust the height according to actual needs. To meet production needs, the position of the tension roller 7 is precisely controlled. When dealing with fabrics of different thicknesses, the electric lifting rod 4 can extend or shorten its output end to drive the mounting frame 5 to rise or fall, thereby maintaining the appropriate tension between the tension roller 7 and the fabric. The electric rotating shaft 6 can drive the tension roller 7 to rotate. During the fabric conveying process, the tension roller 7 not only plays the role of tensioning the fabric, but also assists in the fabric conveying during rotation. Moreover, by adjusting the speed of the electric rotating shaft 6, the tension of the fabric and the conveying speed can be further adjusted to meet the requirements of different production processes. A fixing plate 10 is fixedly installed between the bottoms of every two adjacent connecting plates 8. A lint cleaning component 9 penetrates the bottom of the fixing plate 10 and the bottom of the tension roller 7.

[0023] Please see Figure 2-4 The lint removal assembly 9 includes a dust collection box 91 and a suction seat 96. The dust collection box 91 is fixedly installed at the bottom of the fixing plate 10, and the suction seat 96 is fixedly installed at the top of the fixing plate 10. A suction groove 97 is provided on the top of the suction seat 96 and directly below the tension roller 7. A silicone scraper 99 is fixedly installed on one side of the top of the suction seat 96 and at the bottom of the roller surface of the tension roller 7. An air pump 92 is fixedly installed on one side of the dust collection box 91. An air extraction pipe 93 is connected between the air inlet of the air pump 92 and one side of the dust collection box 91, and an air outlet pipe 94 is connected to the air outlet of the air pump 92. A filter plate 95 is horizontally embedded inside the dust collection box 91 and above the air extraction pipe 93. Multiple conveying pipes 98 are evenly connected from front to back at the bottom of the suction groove 97. The bottom ends of the conveying pipes 98 pass through the suction seat 96 and the fixing plate in sequence. 10 extends into the dust collection box 91. The filter plate 95 is horizontally embedded inside the dust collection box 91 and located above the exhaust pipe 93. It can effectively filter the lint in the air, making the exhaust air cleaner and avoiding pollution to the production environment. The air pump 92 is the power source of the entire lint cleaning assembly 9. When the air pump 92 is started, it will draw the air out of the dust collection box 91 through the exhaust pipe 93, so that a negative pressure is formed in the dust collection box 91. Under the action of negative pressure, the lint in the suction groove 97 will be sucked into the dust collection box 91. After being filtered by the filter plate 95, the clean air is discharged through the exhaust pipe 94. The exhaust pipe 94 is bent at a right angle, and the exhaust port is not aligned with the conveyed fabric, so that the airflow discharged from the exhaust pipe 94 will not impact the conveyed fabric.

[0024] Please see Figure 2-3 The bottom of the main cross-section of the suction trough 97 is shaped like an inverted bucket. This shape design can better guide the lint into the suction trough 97 and improve the suction efficiency. The suction trough 97 is connected to the dust collection box 91 through multiple conveying pipes 98. The conveying pipes 98 are fixedly connected to the suction base 96, the fixed plate 10, and the dust collection box 91, ensuring that the lint will not leak during the conveying process. The main cross-section of the silicone scraper 99 is triangular. The top of the silicone scraper 99 is in contact with the roller surface of the tension roller 7. During the rotation of the tension roller 7, the silicone scraper 99 can scrape off the lint attached to the roller surface. The scraped lint will fall into the suction trough 97 and then be sucked into the dust collection box 91 through the conveying pipes 98.

[0025] Please see Figure 3-4The dust collection box 91 has a door fixed to the front with screws. This design facilitates the cleaning and maintenance of the inside of the dust collection box 91. When the dust and debris in the dust collection box 91 accumulate to a certain level, the operator can easily open the door to clean out the dust and debris. Both sides of the inner wall of the dust collection box 91 are provided with slots for fitting the filter plate 95. The end of the slots on both sides of the inner wall of the dust collection box 91 near the door is open, which facilitates the installation and removal of the filter plate 95. In addition, rubber strips are fixedly embedded in the slots. The rubber strips can play a sealing role to prevent dust and debris from leaking out from the gap between the slots and the filter plate 95.

[0026] Detailed Implementation: In the multi-station production process of circular knitting fabrics, the fabric production requirements of different stations vary. The multi-station tensioning structure of this utility model can specifically meet these requirements. For fabrics of different thicknesses, the electric lifting rod 4 serves as the core adjustment component, receiving intelligent instructions from the control system or manually set parameters. Since parameters can be set independently for each station, the electric lifting rod 4 of each station can individually extend or shorten its output end according to the fabric thickness information of its station, thereby driving the mounting frame 5 to rise or fall. Because the tension roller 7 is mounted on the mounting frame 5, the distance between the tension roller 7 and the fabric at each station can be flexibly changed, thereby independently adjusting the tension of the fabric by the tension roller 7 at each station. This ensures that the fabric at each station maintains a suitable tension state throughout the production process. The electric rotating shaft 6 drives the tension roller 7 to rotate. During the fabric conveying process, the rotation of the tension roller 7 not only tensions the fabric but also assists in the fabric conveying process. Furthermore, by adjusting the rotation speed of the electric rotating shaft 6, the rotation speed of the tension roller 7 can be changed, thereby further adjusting the tension and conveying speed of the fabric to meet the requirements of different production processes.

[0027] When the tension roller 7 rotates, the silicone scraper 99 that is in contact with its roller surface begins to work. The silicone scraper 99 is triangular in shape, with its top end in contact with the roller surface of the tension roller 7. During the rotation of the tension roller 7, it can scrape off the lint attached to the roller surface. The scraped lint will fall into the dust collection groove 97 at the top of the dust collection seat 96. The bottom of the main cross section of the dust collection groove 97 is shaped like an inverted bucket. This shape is conducive to guiding the lint to concentrate and improving the dust collection efficiency.

[0028] The air pump 92, as the power source of the lint cleaning component 9, draws air from the dust collection box 91 through the suction pipe 93 after starting, creating a negative pressure inside the dust collection box 91. Under the action of negative pressure, the lint in the suction groove 97 is sucked into the dust collection box 91. The lint enters the dust collection box 91 through the conveying pipe 98. Since the conveying pipe 98 is fixedly connected to the suction seat 96, the fixing plate 10 and the dust collection box 91, leakage of lint during the conveying process is effectively prevented. The lint entering the dust collection box 91 is blocked by the filter plate 95 horizontally embedded above the suction pipe 93. The filter plate 95 can effectively filter the lint in the air, so that the filtered clean air is discharged through the exhaust pipe 94, avoiding pollution to the production environment. The exhaust pipe 94 is bent at a right angle, so that the airflow discharged from the exhaust pipe 94 will not impact the conveyed fabric.

[0029] When the lint accumulates to a certain level inside the dust collection box 91, the operator can open the door on the front of the dust collection box 91, which is fixed with screws, to clean the inside of the dust collection box 91. The inner walls of the dust collection box 91 have slots on both sides that are fitted with filter plates 95. The slots are open at the end near the door, making it convenient for the operator to install and remove the filter plates 95 for cleaning or replacement. The rubber strips fixedly embedded in the slots play a sealing role, preventing lint from leaking from the gap between the slots and the filter plates 95, and ensuring the normal operation of the lint cleaning system.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
